Description

Technical Field

[0001] This invention belongs to the technical field of automated processing equipment for automotive clock spring components, specifically relating to an automated production equipment for clock spring cables. Background Technology

[0002] The clock spring, also known as the steering wheel airbag clock spring, is a core safety component that connects the driver's side airbag to the vehicle's wiring harness. The flat cable inside needs to be fitted with connecting pieces with pins at both ends. The production process requires multiple steps, including cable punching inspection, inkjet coding traceability, connecting piece riveting, spot welding to remove fly wire, full electrical performance inspection, and UV coating and curing of the weld points.

[0003] The current processing of flat cables for automotive clock springs uses a segmented, single-machine, independent operation, with each process relying on separate equipment and manual handling of workpieces, which has many drawbacks: 1. The cable pretreatment process is fragmented: cable punching, hole position detection, inkjet printing, and QR code verification are done on multiple machines with manual loading and unloading, resulting in poor processing consistency, defective products cannot be removed online in advance, and serious waste of raw materials; 2. Insufficient reliability of connection between connecting piece and cable: Traditionally, only spot welding is used. Long-term reciprocating twisting and pulling of the steering wheel can easily cause the weld to break. Some riveting and welding equipment does not have an integrated conveyor line. The riveting and welding stations are separated, and secondary transfer can cause positioning misalignment. After welding, the molten metal flying wires between the weld points can easily connect to adjacent copper wires. After installation, short circuits can cause airbag failure. There is no automated flying wire removal mechanism. Relying on manual cleaning can easily scratch the weld points. 3. Delayed and one-sided electrical testing: After welding, manual handheld multimeters are used for point-by-point testing, which cannot simultaneously test both ends of the cable. The four tests of continuity, resistance, insulation and short circuit are performed in steps, resulting in a high rate of missed detections. Manually recorded data cannot be traced. 4. Lack of solder joint protection procedures: Currently, there is a lack of protective adhesive coating process for clock spring cables, and there is no synchronous UV curing station, which makes solder joints prone to oxidation and desoldering. 5. Workpiece carriers cannot circulate automatically: The existing production line only has a forward conveying channel. After the finished product is unloaded, the empty tooling needs to be manually carried back, which occupies manpower, lengthens the cycle time, and limits the degree of automation. 6. Poor workpiece positioning accuracy: There is no unified tooling for each machine, each machine loads and unloads materials separately, resulting in large repeated positioning errors. The lifting and locking structure is missing, causing workpieces to shift during processing and resulting in a low yield rate. 7. Low level of automation, large labor load, long cycle time of single process, making it difficult to adapt to the requirements of large-scale production of automotive parts with high reliability and traceability. Summary of the Invention

[0004] The main objective of this invention is to provide an automated production equipment for clock spring cables, addressing the technical shortcomings of existing equipment such as segmented single-machine processing, manual transfer, inability to automatically return tooling, poor positioning accuracy, insufficient connection strength, potential short circuits due to fly filaments, incomplete electrical testing, poor adhesive coating consistency, and lack of production traceability. This equipment achieves continuous automated processing of flat cables from raw material feeding to finished product curing. It features forward conveying channels and reverse return channels to enable fully automated carrier circulation, simultaneously completing processing at both ends, dual rigid positioning, automated fly filament removal, synchronous electrical inspection at both ends, and triaxial precision adhesive coating and curing.

[0012] As a further preferred embodiment of the above technical solution, the adhesive application device further includes an adhesive application module and a curing module, wherein: The adhesive application module includes a first adhesive application unit and a second adhesive application unit.

[0013] As a further preferred technical solution to the above technical solution, the overall working process of the equipment is as follows: Step 1, Cable Pre-treatment and Feeding: The cable feeding device feeds out flat cables through the unwinding mechanism, and the traction mechanism feeds the cables to the punching mechanism to complete the punching at both ends. The CCD camera at the hole position detects the appearance and size of the punched holes. Cables with poor punching are directly rejected. Qualified cables enter the laser marking station to be engraved with traceability QR codes. The QR code CCD camera verifies the integrity of the QR code. Cables with unqualified QR codes are diverted and scrapped. Qualified pre-treated cables are cut and then conveyed to the riveting device feeding area. Step 2, Connecting Piece Fixing and Cable Pre-fitting: The riveting device's transmission module enters the connecting piece loading position, the lifting unit raises and locks the placement base, and the external robot places the connecting piece with the punched mounting head on the first and second end placement blocks. The stabilizing cylinder clamps and fixes the connecting piece laterally. The lifting unit lowers and unlocks, the placement module is transferred to the cable pre-installation position, the lifting unit is raised and positioned again, and the first and second cable clamping units simultaneously grab the pre-processed flat cable, and the punched holes at both ends of the cable are respectively fitted onto the punched mounting heads of the connecting pieces on both sides. The gripper is reset. Step 3, Simultaneous Mechanical Riveting at Both Ends: The placement module is transported to the riveting position along the first continuous conveying channel. The lifting unit locks the base, and the first and second end riveting units simultaneously press down the riveting heads to squeeze the punching installation heads flat, thereby achieving mechanical riveting and fixing of the flat cable and the connecting piece. After riveting is completed, the riveting unit resets, the lifting unit descends, and the placement module is transported to the welding device. Step 4, Double-sided synchronous spot welding and automated fly wire removal: The placement module is transported to the welding position, the lifting unit is raised and locked, the first and second welding units operate synchronously, the upper and lower welding guns press against each other to complete double-sided spot welding at both ends of the cable, forming multiple sets of independent welding areas with gaps; after welding, the placement module is transferred to the fly wire removal position, the lifting unit is repositioned, the protrusion of the fly wire removal pressure block is inserted into the gap of the welding area to cut off the connecting fly wire, eliminating the risk of short circuit; after the fly wire is cleaned up, the placement module is transferred to the electrical performance testing device; Step 5, synchronous electrical performance testing at both ends: When the placement module arrives at the testing position, the lifting unit is raised and locked, and the testing units on both sides descend synchronously, contacting the connecting pins of the connecting piece, and synchronously performing electrical tests including continuity, DC resistance, insulation withstand voltage, and short circuit; bind a QR code to store all test data, and workpieces with electrical defects are marked as defective products, which are then automatically diverted, and qualified workpieces are transported to the gluing device with the transmission module; Step 6, Weld Joint Adhesive Application and Synchronous UV Curing: Qualified workpieces are conveyed to the adhesive application position, the lifting unit locks the base, and the first and second adhesive application units work in three-axis linkage to evenly apply UV protective adhesive to both ends of the weld joints; after adhesive application, the placement module is transferred to the curing position, positioned corresponding to the lifting unit, and the curing lamps on both sides synchronously irradiate the weld joints downwards, allowing the UV adhesive to fully cure and form an insulating protective layer; after curing, the lifting unit unlocks, and the transmission module conveys the placement module carrying the finished product to the unloading station, where the robot arm removes the finished product to obtain the completed workpiece; the unloaded placement module switches to the return module of the adhesive application device, and sequentially passes through the return modules corresponding to the electrical performance testing device, welding device, and riveting device along the second continuous conveying channel, returning to the front end of the riveting device, completing the full cycle of the placement module.

[0014] The beneficial effects of this invention are as follows: 1. Two-way dual-channel fully automatic circulation of carriers eliminates the need for manual return of tooling: This invention sets up a first continuous forward conveying channel and a second continuous reverse return channel. After the material is finished and unloaded, the empty placement module automatically returns to the starting point of the production line. There is no need for manual handling of tooling, which greatly reduces labor, shortens the production cycle, and realizes truly unmanned continuous production. 2. Fully integrated continuous automated production: This invention integrates cable pretreatment, riveting, welding to remove fly wire, electrical full inspection, and glue coating and curing into a single production line. The module is placed for material transfer, eliminating manual handling of workpieces. The processing cycle of a single cable is greatly shortened, reducing production costs. 3. Riveting and welding composite connection to improve tensile reliability: The front mechanical riveting fixes the cable and connecting piece, and then double-sided spot welding is performed. The double-combined structure resists the reciprocating torsion and pulling of the steering wheel, and prevents the airbag from breaking due to weld point breakage, which significantly improves driving safety performance. 4. Automated elimination of fly wire short circuit hazards: After welding, a fly wire crushing mechanism is provided. The pressure block protrusion is precisely inserted into the gap of the welding area to automatically remove connected fly wires, replacing manual cleaning, avoiding the risk of copper wire short circuit and airbag failure, while also preventing manual scratching of the solder joint. 5. Dual rigid positioning for high machining accuracy: Each station is equipped with a lifting insert locking base and a stable cylinder clamping connecting plate for dual limiting, ensuring no workpiece offset or shaking, precise alignment for riveting, welding, and gluing, and a significant reduction in defect rate. 6. Simultaneous processing at both ends doubles production efficiency: Riveting, welding, wire cleaning, electrical testing, and adhesive curing are all set up with symmetrical dual units on the left and right sides, which can complete the processing of both ends of the cable simultaneously without the need for two separate operations, making it suitable for mass production lines. 7. Online inspection and traceability of cable pretreatment: The cable feeding process integrates punching visual inspection and QR code inkjet printing re-inspection. Unqualified raw materials are rejected in advance, and QR codes are bound to the full process data of a single product to achieve full life cycle quality traceability. 8. Electrical synchronous testing, full coverage: The synchronous probes on both sides complete the continuity, resistance, insulation and short circuit tests at one time, with no missed tests. It automatically marks and diverts defective products to avoid electrical faults after the finished products are off the production line. 9. Triaxial precision glue application and synchronous UV curing: The X / Y / Z triaxial glue application head is compatible with multiple specifications of solder joints, and the glue application amount is uniform and controllable. The synchronous curing lamp quickly cures the protective glue, isolates the solder joint oxidation, and improves the insulation performance and structural strength of the solder joint. 10. The entire line is centrally controlled and managed, including forward conveying, reverse transmission, processing sequence and testing data of each workstation. The equipment linkage logic is stable, fault alarms are automatic, and production data can be stored and traced for a long time. Attached Figure Description

[0028] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0029] In the preferred embodiments of the present invention, those skilled in the art should note that the bell springs, cables, and connecting pieces involved in the present invention can be considered as prior art.

[0030] Preferred embodiment.

[0031] This invention discloses an automated production equipment for clock spring cables, comprising a cable feeding device, a riveting device, a welding device, an electrical performance testing device, and a gluing device arranged sequentially along the production direction, as well as a placement module 100 that circulates throughout the entire production line, wherein: The placement module 100 serves as a unified circulating carrier for the entire line, used to carry and position the connecting piece and flat cable. After being transferred by each transmission module, the cable flows sequentially through each station of riveting, welding, electrical performance testing, and gluing. It works in conjunction with a stabilizing cylinder to clamp the workpiece and a lifting unit to achieve rigid limiting during processing, ensuring consistent positioning throughout the entire process. like Figure 11 As shown, the placement module 100 includes a placement base 110, a plurality of first-end placement blocks 120, a plurality of second-end placement blocks 130, and a plurality of stabilizing cylinders 140. The first-end placement blocks 120 and the second-end placement blocks 130 are respectively distributed on the top two sides of the placement base 110, and the stabilizing cylinders 140 are provided on the side of the first-end placement blocks 120 and the side of the second-end placement blocks 130. The stabilizing cylinders 140 are used to fix the connecting pieces 2 installed on the first-end placement blocks 120 and the second-end placement blocks 130 (the connecting pieces are moved to the corresponding placement blocks by the connecting piece handling gripper, and then the connecting pieces are fixed by the stabilizing cylinders. In the riveting device, this facilitates the subsequent cable clamping module to attach the two ends of the cable to the mounting head of the connecting piece. In other devices, it is used to stabilize the cable between the two connecting pieces, which facilitates welding, electrical performance testing, and gluing processes).

[0032] The riveting device, welding device, electrical performance testing device, and gluing device are each equipped with an independent transmission module 200 and a return module (not shown). The transmission modules 200 are connected end to end to form a first continuous conveying channel, which is used to carry and drive the placement module 100 carrying the cable to be transferred sequentially along the cable production direction. The return modules are connected end to end to form a second continuous conveying channel, which is used to carry and drive the empty placement module 100 to be transferred sequentially along the production reverse direction (after the gluing device completes the gluing, the cable is unloaded, and the empty placement module is transferred to the riveting device through the return module, where a new cable and connecting piece are put in again), thereby realizing the circulation of the entire line carrier. like Figure 12As shown, the transmission module 200 is used to drive the placement base 110 to move; the transmission module 100 includes a first transmission belt mounting frame 210, a second transmission belt mounting frame 220, a first transmission belt 230, a second transmission belt 240, and a transmission belt drive motor 250. The first end of the first transmission belt mounting frame 210 and the first end of the second transmission belt mounting frame 220 are each provided with a drive wheel 260, and the second end of the first transmission belt mounting frame 210 and the second end of the second transmission belt mounting frame 220 are each provided with a driven wheel 270. The first transmission belt 230 is located on the first transmission belt mounting frame 210 and is installed between the corresponding drive wheel and driven wheel. The second transmission belt 240 is located on the second transmission belt mounting frame 220 and is installed between the corresponding drive wheel and driven wheel. The first transmission belt 230 and the second transmission belt 240 are used to support the placement base 110; the transmission belt drive motor 250 is used to simultaneously drive the two drive wheels (thereby driving the transmission belts to move on their respective transmission belt mounting frames).

[0033] It is worth mentioning the transmission module. In the riveting device, firstly, the drive base is moved to the connecting piece placement position, and the connecting piece is placed using the connecting piece handling gripper; then, when it is necessary to fit the punched hole of the flat cable onto the corresponding punched mounting head, the transmission module moves the base to the pre-installation position, and the cable clamping module's two grippers perform the pre-installation; then, the transmission module moves the base to the riveting position, and the riveting is performed using the riveting module. After completion, the base is moved to the adjacent transmission module of the welding device. In the welding device, firstly, the placement base is driven to move to the welding position and welding is performed by the welding module; then, the placement base is moved to the wire-flying processing position and processed by the wire-flying processing module. After completion, the placement base is moved to the adjacent transmission module of the electrical performance testing device. In the electrical performance testing device, the drive placement base is moved to the electrical performance testing position, processed by the testing unit, and then the placement base is moved to the adjacent transmission module of the glue application device. In the adhesive application device, the placement base is driven to move to the adhesive application position, and adhesive is applied through the adhesive application module; then, the placement base is moved to the curing position, and processed by the curing module. After completion, the placement base is moved to the adjacent transfer module of the next process for corresponding processing.

[0034] Each of the transmission modules 200 has multiple lifting units 280 at its bottom and is located at a corresponding processing position. Each lifting unit 280 includes a lifting cylinder 281, a lifting plate 282, and a number of positioning pins 283. The lifting plate 282 is fixedly installed on the driving end of the lifting cylinder 281, and the positioning pins 283 are fixedly installed on the top of the lifting plate 282. The positioning pins 283 are used to be inserted into the bottom insertion hole 111 of the placement base 110.

[0035] It is worth mentioning the lifting unit. When the placement base is moved to the corresponding processing position via the transmission module, such as the connecting piece placement position, pre-installation position, riveting position, welding position, wire handling position, electrical performance testing position, glue application position, curing position, etc., the lifting cylinder is activated, which moves the lifting plate upward and inserts the positioning pin into the bottom socket. This lifts the placement base, causing it to detach from the two transmission belts, thus fixing the placement base in its current position for processing by the corresponding processing module.

[0036] When the placement module moves to the riveting position, welding position, electrical performance testing position, or adhesive application position, the corresponding lifting unit is activated, the positioning pin is inserted into the bottom hole of the placement base to lift the base, and the bidirectional clamping connecting piece of the stabilizing cylinder forms a double positioning. After processing is completed, the lifting unit descends and unlocks, and the placement module is transferred downstream with the transmission module. After the finished product is unloaded, the unloaded placement module switches to the return transmission module and is transported in reverse along the second continuous conveying channel to the front end of the riveting device for recycling.

[0037] The cable feeding device is used for feeding flat cable raw materials and sequentially completes cable pretreatment including cable end punching, punch hole position CCD visual inspection, cable surface coding, coding QR code CCD visual re-inspection, and cable cutting. The cable feeding device includes a cable unwinding mechanism, a punching mechanism, a hole-position CCD camera, a laser marking mechanism, a QR code reading CCD camera, and a cable conveying and traction mechanism. The cable unwinding mechanism continuously conveys flat cables, and the punching mechanism punches holes at both ends of the cable to accommodate matching connector mounting heads. The hole-position CCD camera captures images of the punched holes and determines whether the hole size and position are qualified. The laser marking mechanism engraves a traceability QR code on the cable surface. The QR code CCD camera scans the QR code to complete information verification, and unqualified cables are rejected in advance.

[0038] For riveting devices, such as Figure 1-4 As shown in Figures 11-12. The riveting device is used to place the cut cable into the placement module and to simultaneously and mechanically rivet the connecting piece with the punched mounting head to the punched holes at both ends of the cable; it also includes a cable clamping module and a riveting module, wherein: The cable clamping module is used to clamp both ends of the cable 1 and place them respectively at the corresponding connecting pieces 2 located on the placement block. It includes a first cable clamping unit 310 and a second cable clamping unit 320. The first cable clamping unit 310 is used to clamp one end of the cable 1 and the second cable clamping unit 320 is used to clamp the other end of the cable 1. The first cable clamping unit 310 and the second cable clamping unit 320 both include a horizontal cable clamping driver 311, a vertical cable clamping driver 312, and a cable clamping gripper 313. The vertical cable clamping driver 312 is installed at the driving end of the horizontal cable clamping driver 311, and the cable clamping gripper 313 is installed at the driving end of the vertical cable clamping driver 312. (The first / second cable clamping unit grabs the cable with several punches at both ends from the cable loading point and places it at the connecting piece. The connecting piece is provided with a corresponding punch mounting head (preferably conical), so that the punches are fitted into the punch mounting head to complete the pre-installation; specifically, the punches at one end of the cable are fitted into the mounting head of the connecting piece located at the first end placement block, and the punches at the other end of the cable are fitted into the mounting head of the connecting piece located at the second end placement block).

[0039] The riveting module includes a plurality of first-end riveting units 330 and a plurality of second-end riveting units 340. The first-end riveting units 330 are located above the first-end placement block 120 and are used to rivet the connecting piece 2 and the cable 1 located on the first-end placement block 120. The second-end riveting units 340 are located above the second-end placement block 130 and are used to rivet the connecting piece 2 and the cable 1 located on the second-end placement block 130.

[0040] Both the first-end riveting unit 330 and the second-end riveting unit 340 include a vertical riveting cylinder 331, a riveting pressure head mounting seat 332, and a riveting pressure head 333. The riveting pressure head mounting seat 332 is installed on the drive end of the vertical riveting cylinder 331, and the riveting pressure head 333 is fixedly installed on the riveting pressure head mounting seat 332. (When riveting is required, the vertical riveting cylinder is activated, which simultaneously drives the riveting pressure head mounting seat and the riveting pressure head to move downward, so that the riveting pressure head applies force to the mounting post of the connecting piece with the cable, flattening the conical tip, thereby fixing the connecting piece to both ends of the cable. If riveting is not performed and the connecting end of the connecting piece is directly welded to the connecting end of the cable, then in actual use, the cable will continuously rotate with the steering wheel, and the tensile strength of the weld is poor, which will lead to the weld breaking, directly affecting product quality and safety.)

[0041] More specifically, the cable 1 is a flat cable with several punches 11 at both ends (avoiding the copper wires in the cable); the connecting piece 2 is provided with several punched mounting heads 21, and the punches 11 are fitted onto the corresponding punched mounting heads 21.

[0042] The working process of the riveting device is as follows: Step 1: Connecting piece loading and positioning / locking station: The transmission belt drive motor 250 of the transmission module 200 drives the drive wheel 260 and the driven wheel 270 to rotate, and transports the placement base 110 of the placement module 100 to the connecting piece loading station through the first transmission belt 230 and the second transmission belt 240. When the lifting unit 280 below the workstation is activated, the lifting cylinder 281 pushes the lifting plate 282 upward, and the positioning pin 283 is inserted into the bottom hole of the placement base 110, lifting the placement base 110 away from the conveyor belt and completing rigid locking to prevent processing from shaking and shifting. The external connecting piece handling gripper places the connecting piece with the conical punch mounting head onto the first end placement block 120 and the second end placement block 130 on the placement base 110, respectively. The stabilizing cylinders 140 on the sides of each placement block extend to press and fix the connecting plates, preventing the connecting plates from shifting. After the material is fed, the lifting cylinder 281 drives the lifting plate 282 to descend, the positioning pin 283 disengages from the base insertion hole, and the placement base 110 falls back onto the surface of the conveyor belt.

[0043] Step 2: Automatic clamping and splicing of flat cables at the pre-installation station: The conveyor belt continues to operate, transporting the placement base 110 carrying the connecting piece to the cable clamping pre-assembly station; The lifting unit 280 at this workstation is raised again, and the positioning pin 283 locks the base 110 in place. When the cable clamping module 300 is started, the first cable clamping unit 310 and the second cable clamping unit 320 operate synchronously: the cable clamping horizontal driver 311 drives the gripper to move laterally to the cable feeding area, and the cable clamping vertical driver 312 controls the cable clamping gripper 313 to descend and grip the flat cable. The gripper moves the cable back to the top of the placement module, aligns the pre-drilled holes at both ends of the flat cable with the conical punch mounting heads of the connecting plates on the first placement block 120 and the second placement block 130, and completes the pre-fitting and positioning of the cable and the connecting plates. The gripper releases the cable and resets, the lifting unit 280 descends, and the placement base 110 is transferred to the riveting station by the conveyor belt.

[0044] Step 3: Simultaneous riveting and forming station at both ends: The transmission module 200 transports the placement base 110 to the riveting station, and the lifting unit 280 lifts the base and locks it in place. The riveting module 400 starts synchronously, and the first riveting unit 330 and the second riveting unit 340 press down at the same time: the riveting vertical cylinder 331 drives the riveting pressure head mounting seat 332 and the riveting pressure head 333 to move downward. The 333 riveting head presses the conical punch mounting head protruding from the connecting piece, flattening the conical tip so that the connecting piece firmly clamps the end of the flat cable, achieving mechanical riveting fixation; After the riveting pressure is maintained, the vertical riveting cylinder 331 retracts upwards, and the riveting pressure head is reset as a whole.

[0045] Step 4: Finished product transfer and unloading, entering the cycle: After the riveting process is completed, the lifting unit 280 descends and unlocks, and the base 110 falls back onto the conveyor belt. The conveyor belt drives the placement base 110 to transport downstream, sending the riveted clock spring cable into the next processing step.

[0046] For welding equipment, such as Figure 5-8 As shown in Figures 11-12. The welding device is used for simultaneous double-sided spot welding of the welding area of ​​the riveted cable and connecting piece, and automatically presses off and removes welding wire; it also includes a welding module and a wire handling module (…). Figure 5 Two placement modules are shown, just in different positions: one for soldering and one for wire finishing (there is actually only one placement module). The welding module includes a plurality of first welding units 410 and a plurality of second welding units 420. The first welding units 410 are located on the side close to the first placement block 120 and are used to weld the connecting piece 2 located on the first end placement block 120 and one end of its connecting cable 1. The second welding units 420 are located on the side close to the second placement block 130 and are used to weld the connecting piece 2 located on the second end placement block 130 and the other end of its connecting cable 1. The first welding unit 410 and the second welding unit 420 both include a welding horizontal actuator 411, a welding connecting plate 412, a first welding vertical actuator 413, a second welding vertical actuator 414, an upper welding torch 415, and a lower welding torch 416, wherein: The welding connection plate 412 is installed on the drive end of the welding horizontal driver 411, the first welding vertical driver 413 is installed on the top of the welding connection plate 412 and the second welding vertical driver 414 is installed on the bottom of the welding connection plate 412, the upper welding gun 415 is installed on the drive end of the first welding vertical driver 413 and faces downward, and the lower welding gun 416 is installed on the drive end of the second welding vertical driver 414 and faces upward. (When the drive placement base moves to the welding position through the transmission module, the first welding unit and the second welding unit at both ends are driven simultaneously. The horizontal driver moves the welding connection plate close to the corresponding placement block, so that the upper welding gun is above the placement block and the lower welding gun is below the placement block. Then the first welding vertical driver and the second welding vertical driver are started, respectively driving the upper welding gun to move down to the upper welding position of the connecting piece and the cable, and driving the lower welding gun to move up to the lower welding position of the connecting piece and the cable. The upper and lower parts are welded by the welding gun, thereby completing the welding of the cable and the connecting piece.)

[0047] The wire-flying processing module is located downstream of the welding module and includes a first wire-flying processing unit 430 and a second wire-flying processing unit 440. The first wire-flying unit 430 is located on the side close to the first placement block 120 and is used to perform wire-flying processing on the connecting piece 2 located on the first placement block 120 and one end of its welding cable 1. The second wire-flying unit 440 is located on the side close to the second placement block 130 and is used to perform wire-flying processing on the connecting piece 2 located on the second placement block 130 and the other end of its welding cable 1.

[0048] Both the first fly filament processing unit 430 and the second fly filament processing unit 440 include a fly filament processing horizontal driver 431, a fly filament processing vertical driver 432, and a fly filament processing pressure block 433. The fly filament processing vertical driver 432 is mounted on the drive end of the fly filament processing horizontal driver 431, and the fly filament processing pressure block 433 is mounted on the drive end of the fly filament processing vertical driver 432. The pressure end of the fly filament processing pressure block 433 has several protrusions 434 (when the cable and connecting piece are welded, and the drive placement base moves to the fly filament processing position via the transmission module, the horizontal driver...). The actuator and vertical actuator move the fly wire removal block above the welding point. Because the welding point is not a single, integrated weld, but rather consists of multiple independent welding areas (corresponding to different copper wires and connecting pins in the cable), with gaps between adjacent welding areas, fly wires may occur during the welding process. These fly wires connect the welding areas, potentially causing short circuits and other malfunctions during subsequent use. Therefore, this needs to be addressed. The specific solution is as follows: the vertical cylinder moves the fly wire removal block downwards, and multiple protrusions are inserted into the corresponding gaps to break and remove the fly wires.

[0049] Preferably, the welding point 2 between the cable 1 and the connecting piece is provided with multiple independent welding areas 31 and gaps 32 are provided between adjacent welding areas 31.

[0050] The electrical performance testing device is used to simultaneously perform electrical performance tests such as continuity, DC resistance, insulation withstand voltage, and short circuit at the welding points at both ends of the cable. For adhesive application devices, such as Figure 9-12 As shown. The adhesive application device is used to simultaneously apply UV adhesive and cure it under UV light at the solder joints at both ends of the cable. It also includes an adhesive application module and a curing module, wherein: The adhesive application module includes a first adhesive application unit 510 and a second adhesive application unit 520. The first adhesive application unit 510 is located on the side close to the first placement block 120 and is used to apply adhesive to one end of the connecting piece 2 and its welding cable 1 located on the first placement block 120. The second adhesive application unit 520 is located on the side close to the second placement block 130 and is used to apply adhesive to the other end of the connecting piece 2 and its welding cable 1 located on the second placement block 130. The first glue application unit 510 and the second glue application unit 520 both include a first glue application horizontal driver 511 (X-axis), a second glue application horizontal driver 512 (Y-axis), a glue application vertical driver 513 (Z-axis), and a glue application head 514. The second glue application horizontal driver 512 is installed at the drive end of the first glue application horizontal driver 511, and the glue application vertical driver 513 is installed at the drive end of the second glue application horizontal driver 512. The glue application head 514 is installed at the drive end of the glue application vertical driver 513. (After the cable and connecting piece are welded and the wire is scraped, the drive placement base is moved to the glue application position through the transmission module. The first / second horizontal driver and the vertical driver move the glue application head above the welded area. The vertical cylinder drives the glue application head to move down, thereby applying UV glue to the welded area.)

[0051] The curing module is located downstream of the adhesive coating module and includes a first curing unit 530 and a second curing unit 540. The first curing unit 530 is located on the side close to the first placement block 120 and is used to cure the connecting piece 2 located on the first end placement block 120 and one end of its welding cable 1. The second curing unit 540 is located on the side close to the second placement block 130 and is used to cure the connecting piece 2 located on the second end placement block 130 and the other end of its welding cable 1.

[0052] The first curing unit 530 and the second curing unit 540 both include a curing bracket 531 and a curing lamp 532. The curing lamp 532 is fixedly installed on the curing bracket 531 and the curing lamp 532 shines downward (when the glue is applied, the drive placement base moves to the curing position through the transmission module, and the glued area at the welding point is irradiated by the curing lamp, thereby curing the glued area).

[0053] The working process of the adhesive application device is as follows: The workflow of this invention is as follows: 1. Loading: The cables and connecting pieces that have been welded and are located in the placement module of the previous process are transferred to the transmission module 200 of this device. 2.

Conveying to the curing position: After the adhesive is applied, the lifting unit descends, the conveyor belt moves the placement base to the curing position, and the lifting unit locks the workpiece again; 5.

[0054] The overall workflow of the equipment is as follows: Step 1, Cable Pre-treatment and Feeding: The cable feeding device feeds out flat cables through the unwinding mechanism, and the traction mechanism feeds the cables to the punching mechanism to complete the punching at both ends. The CCD camera at the hole position detects the appearance and size of the punched holes. Cables with poor punching are directly rejected. Qualified cables enter the laser marking station to be engraved with traceability QR codes. The QR code CCD camera verifies the integrity of the QR code. Cables with unqualified QR codes are diverted and scrapped. Qualified pre-treated cables are cut and then conveyed to the riveting device feeding area. Step 2, Connecting Piece Fixing and Cable Pre-fitting: The riveting device's transmission module enters the connecting piece loading position, the lifting unit raises and locks the placement base, and the external robot places the connecting piece with the punched mounting head on the first and second end placement blocks. The stabilizing cylinder clamps and fixes the connecting piece laterally.
