1, introductive go up oneself 80 time metaphase produces the century since the car, carry by low Duan Xianggao gradually as product of car of Chang'an automobile group, by onefold breed to much breed, by small car to own brand car the development of whole set, the solder deliver a child of Chang'an produces what much breed, hi-tech applies in great quantities stage by stage on the line to solder equipment, solder the applied limits of domain new technology is ceaseless also and patulous. Through 20 old and long-term practice, inapplicable solder deliver a child produces equipment to be washed out gradually, mature to function, suit to solder car product line needs and the facility with use larger amount, chang'an and equipment manufacturer formed long-term strategy collaboration to study associate, be opposite all sorts of soldering then equipment is optimized ceaselessly, offerred much performance stability, fault rate for car solder wiring price of low, sex compares expensive high grade product. At present Chang'an automobile group applies solder equipment can divide roughly it is 4 kinds: Solder directly equipment kind, tool clamping apparatus kind, buckle combine pressure kind, detect tool kind. The article basically solders in the light of above the equipment use in Chang'an automobile group the problem of circumstance, existence, and the technical promotion of expectation undertakes description and brief analysis. 2, solder directly equipment kind solder directly equipment is to incite what make with this kind of equipment workpiece is together through soldering means agglutinate to solder equipment, what at present the company basically has the following sort is direct solder equipment: Robot of solder of machine of overhead suspension spot welding, dummy, automatic solder, spot welding, arc welding machine implement welder of column of welder of protruding of nut of welder of person, MIG, stationary, snail. Machine of spot welding of overhead suspension of engine of spot welding of ◆ overhead suspension -- the company basically uses Tianjin the product of 7 Gao Ke, performance of this product whole is quite steady, use convenient, safeguard convenient, it is Chang'an company is received in car solder at present the most extensive soldering is used on product line equipment. Pass the collaboration of Chang'an and supplier, the supplier is on the foundation of machine of overhead suspension spot welding, development gave system of group control of engine of overhead suspension spot welding, undertake to machine of overhead suspension spot welding divisional region centralizes pilot system namely. The main function of group control system is to three-phase voltage undertakes real time monitoring, through be restricted to hold control the method ensures the real time of voltage of electrified wire netting is balanced, offer for machine of the spot welding inside real time supervisory system at the same time assure directly, make solder product quality is more stable. This kind of equipment uses in also had produced a few problems: Basically be to solder craft parameter missing, silicon controlled rectifier is direct now and then cause the trouble such as transformer spontaneous combustion. Solder of dummy of ◆ dummy solder, automatic solder -- it is outside of have the aid of solder one kind when the spare parts that solders to connect clamp of not expedite, common solder to cannot solder to soldering on product line artificially undertakes, assisting an orgnaization through solder clamp namely aspirant travel solders, the spare parts position that assists an orgnaization to be brought to need to solder is finished thereby solder. Automatic solder -- be opposite through can making up Cheng controller namely the athletic contrail of solder clamp and solder parameter undertakes automata, make solder clamp undertakes soldering automatically according to the regulation of craft. Two kinds of distinction are in dummy solder, automatic solder not to need artificial operation at automatic solder, dummy solder needs artificial operation. These two kinds solder the trouble of means is little, performance is steady, solder quality is good, but ask to spare parts quality (namely spare parts consistency asks) taller, when asking like short of of spare parts precision easy cause solder equipment malfunction. Can make up Cheng controller to already applied car solder to receive product line in great quantities at present, the following trend is not to use dummy to use automatic solder solder, completely, reduce artificial operation intensity to reduce the moving cost of the enterprise then. Robot of ◆ spot welding, arc welding machine implement robot of person spot welding -- the company used the most typical robot on the world such as COMAU, KUKA, ABB in great quantities at present. No matter the sort of robot, robot noumenon breakdown all less, most equipment malfunction is by the solder that installs on robot arm clamp is reached solder controller is caused. Robot solder clamp controls means to servo control and pneumatic control two kinds of fashion, at present the company is used most is clamp of servo control solder. Servo solder clamp is taller to the precision requirement of the spare parts, if the precision short of of the spare parts asks, the fault rate of clamp of robot servo solder is met very tall, and uphold charge big, spare parts cost is higher also, the cost that goes against an enterprise is managing. The maintenance of pneumatic solder clamp cost is relatively inferior, and safeguard go to the lavatory, the attaint rate that the precision of the spare parts causes to equipment clamp of opposite servo solder is inferior. Arc welding machine implement person -- the company uses robot of brand of two Japan OTC at present, arc solder performance is steady, use reach safeguard convenient, because application is too little incorrect its undertake labor. Welder of MIG of ◆ MIG welder -- common says carbon dioxide protects solder, performance of this equipment whole is steady, fault rate is low, among them the easy attaint of welding torch part that an inadequacy is MIG welder. Because of company application is the MIG welder that American Lincoln offers money, belong to entrance equipment, spare parts is costly (basically point to welding torch) . Through research of Chang'an technology personnel and old practice, at present the welding torch spare parts of this welder uses domestic form a complete set basically already, thereby greatly managing use cost and maintain cost. The another defect of MIG welder is the smoke in using a process, dirt bigger, the company receives product line to use the area of this kind of equipment in car solder, the smoke evacuation that deployed production of American Tang Nasen company at the same time removes dust equipment, in order to make sure the professional health of worker of the operation on product line and work environment do not get pollution.
