Description

Technical Field

[0001] This utility model relates to the field of resistor assembly technology, specifically to a resistor assembly device for a car door anti-pinch strip wiring harness. Background Technology

[0002] In the automotive manufacturing industry, the performance of door anti-pinch strips is directly related to driving safety, and the assembly quality of its internal wiring harness and resistors is a key factor determining the stability of the anti-pinch strip's function. With the continuous improvement of safety standards in the automotive industry and the increasing demand for production efficiency, traditional door anti-pinch strip wiring harness resistor assembly equipment has gradually become unable to meet actual production needs. Many technical shortcomings have been exposed in core processes such as wire stripping, resistor positioning and testing, and wire pressing, which seriously restricts the improvement of production efficiency and product quality.

[0003] Existing assembly equipment typically employs a fixed, rigid wire clamping structure, lacking adaptive adjustment capabilities. It can only clamp wires of a specific diameter, requiring frequent replacement of clamping components when dealing with wires of different specifications. This not only makes the operation cumbersome but also significantly increases process changeover time. Furthermore, due to the lack of guidance in the clamping structure, wires are prone to jamming when placed into the wire slot, often requiring manual adjustment and severely impacting process continuity. Additionally, the wire ejection mechanism is mostly a single-point drive mode, with a limited ejection position that can only act on a fixed part of the wire. This often results in the wire's beginning or end remaining in the wire slot, requiring secondary manual cleaning and further reducing wire stripping efficiency. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This door anti-pinch strip wiring harness resistor assembly equipment utilizes two sets of bow-shaped diaphragm springs with inclined tops, in conjunction with a flexible push plate to form an adaptive clamping mechanism. The inclined surface guides the wires smoothly into the first wire slot, preventing jamming during insertion. The flexible push plate is made of soft material and can be positioned at three points: the beginning, end, and middle of the clamped wire. Simultaneously, using three sets of linearly arrayed ejector components—the first counterweight, the first spring, and the first push rod—corresponding to the beginning, middle, and end of the wire, the counterweight simultaneously ejects the stripped wires when the first placement box rotates. Then, the first counterweight is reset via the first spring, allowing the first push rod to retract to its initial state. The diaphragm spring also drives the flexible push plate to reset through its own elasticity, thus eliminating waiting time and further improving the continuity of the wire stripping process.

[0015] 2. This door anti-pinch strip wiring harness resistor assembly equipment utilizes a convex pin in the mounting assembly to form a spherical engagement with the ball groove of the resistor body. Combined with the return reset of a third spring, this securely locks the resistor body within the second placement box. Even with slight vibrations during equipment operation, the convex pin, through the limiting effect of the ball groove's inner wall, prevents the resistor from shifting laterally or longitudinally. Simultaneously, the sensor light's color change—green light indicating positioning completion and red light indicating finished product ejection—provides real-time feedback on the resistor's status. An industrial camera, aligned with the sensor light's longitudinal and horizontal axes, captures the sensor light signals in real-time. If an anomaly occurs, such as a green light indicating the resistor is not in position or a red light indicating the finished product has not been ejected, the equipment can be immediately stopped to prevent defective semi-finished products from flowing to the next workstation, thereby reducing rework costs due to human error.

[0016] 3. The door anti-pinch strip wiring harness resistor assembly equipment uses a fourth cylinder, a fisheye connector, and a lever for transmission. The lever uses the base as a fulcrum and the fisheye connector eliminates transmission gaps, ensuring that the downward pressure of the pressing head is uniform. This allows the lever structure to amplify the pressing force, achieving tight pressing with a small output. The pressing head is always aligned with the connection between the resistor and the wire, thus avoiding poor contact caused by misalignment. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 10 A door anti-pinch strip wiring harness resistor assembly device includes a support plate 1. The outer wall of the support plate 1 is respectively provided with a partition 2, a final platform 7, a first conveying body 11, and a baffle 20. A first guide groove 3 is opened at the top of the partition 2. One end of a connecting column 5 is fixedly mounted on the outer wall of the partition 2, and a right-side guide plate 4 is fixedly mounted at the other end of the connecting column 5. A window 6 is opened on the outer wall of the partition 2. A first cylinder 10 is fixedly installed at the top of the partition 2, and an industrial camera 9 is fixedly installed at the bottom of the partition 2. A left-side guide plate 8 is fixedly installed on the outer wall of the final platform 7. A first placement box 12 is provided on the outer wall of the first conveying body 11. The outer wall of the placement box 12 is provided with a second guide groove 13. The inner cavity of the first placement box 12 is provided with a wire stripping assembly 14. The telescopic end of the first cylinder 10 is fixedly installed with a slider 15. The bottom of the slider 15 is fixedly installed with a second cylinder 16. The telescopic end of the second cylinder 16 is provided with a mounting plate 17. The top of the mounting plate 17 is fixedly installed with a rotary cylinder 18. The outer wall of the output shaft of the rotary cylinder 18 is fixedly installed with a gripper body 19. The inner wall of the baffle 20 is provided with a second conveying body 21. The outer wall of the second conveying body 21 is provided with an installation assembly 22. The top of the baffle 20 is respectively provided with a spot welding body 23 and a wire pressing assembly 24.

[0030] In the above structure, by spot welding the main body 23, after the connection between the resistor body 224 and the wire is pressed together, when the baffle 20 passes over the top of the spot welding main body 23, the spot welding main body 23 will spot weld and fix the connection, thereby realizing the assembly and fixation between the resistor body 224 and the wire.

[0031] In a preferred embodiment: the first guide groove 3, the first cylinder 10, the slider 15, the second cylinder 16, the mounting plate 17, the rotary cylinder 18 and the gripper body 19 are regarded as a set of movable components, and there are two sets of such movable components, which are respectively set to correspond to the two ends of the wire.

[0032] In the above structure, by starting with one end of the wire, the first cylinder 10 is activated, causing its extension end to drive the slider 15 to slide along the inner wall of the first guide groove 3. This moves the second cylinder 16, mounting plate 17, rotary cylinder 18, and gripper body 19 to the gripping position of one end of the wire. Subsequently, by activating the rotary cylinder 18, its rotating end drives the gripper body 19 to rotate 90 degrees to the right. At this time, the gripper body 19 aligns with the wire stripped from the gap between the right side plate 4 and the outer wall of the partition 2, thus gripping the beginning of the wire. Another movable component then performs the same operation to grip the end of the wire. The wire is then rotated 90 degrees from right to left by restarting the rotary cylinder 18, causing its rotating end to drive the gripper body 19 and the clamped wire. Then, by operating the first cylinder 10, its telescopic end drives the first conveyor body 11 to retract to the position corresponding to the second wire groove 222. At this time, when the wire is above the second wire groove 222, the second cylinder 16 is started, causing its telescopic end to drive the mounting plate 17, the rotary cylinder 18, the gripper body 19, and the wire clamped by the gripper body 19 to move downward. Then, by operating the gripper body 19, the clamped wire is released and placed into the inner cavity of the second wire groove 222 for the next work station to operate.

[0033] In a preferred embodiment: the wire stripping assembly 14 includes a third cylinder 141 fixedly mounted on the outer wall of the first placement box 12, a guide block 142 fixedly mounted on the telescopic end of the third cylinder 141, a first wire groove 144 opened in the inner cavity of the first placement box 12, a first square groove 145 opened in the inner wall of the first placement box 12, a cutter 143 fixedly mounted on the bottom of the guide block 142, a diaphragm spring 146 provided in the inner cavity of the first wire groove 144, a flexible push plate 147 fixedly mounted on the outer wall of the diaphragm spring 146, a first sliding groove 148 opened in the inner wall of the first square groove 145, an ejector 149 provided in the inner cavity of the first square groove 145, the ejector 149 including a first counterweight 1491 provided in the inner cavity of the first square groove 145, a first spring 1492 provided on the top of the first counterweight 1491, and a first push rod 1493 fixedly mounted on the top of the first counterweight 1491;

[0034] In a preferred embodiment: the diaphragm spring 146 and the flexible push plate 147 are considered as a set of movable components, and there are two sets of such movable components, which are symmetrically arranged. The cross-section of the two diaphragm springs 146 is arc-shaped, and the top of the two diaphragm springs 146 is inclined. The outer wall of the guide block 142 is slidably fitted to the inner wall of the second guide groove 13. The first slide groove 148 and the ejector 149 are considered as a set of movable components, and there are three sets of such movable components, which are arranged in a linear array. The outer walls of the three first counterweights 1491 are slidably fitted to the inner walls of the three first slide grooves 148. The outer walls of the three first push rods 1493 are through-connected to the inner wall of the first guide groove 144. One end of the three first springs 1492 overlaps with the top of the first counterweight 1491, and the other end overlaps with the inner wall of the first square groove 145.

[0035] In the above structure, the wire is first placed into the first wire groove 144 inside the first placement box 12. During this second placement, the two sets of diaphragm springs 146, which are arc-shaped with inclined tops, will have their middle ends elastically inserted. Since the tops of the diaphragm springs 146 are inclined, the inclined surfaces act as guides during wire insertion, facilitating the wire's smooth entry into the first wire groove 144. Secondly, because the middle end of the first wire groove 144 is convex, it is pushed towards both sides of the inner wall of the first wire groove 144 by the pressure of the wire. This causes the first wire groove 144, located at the beginning and end of the wire, to be lifted by the pressure at its middle end. This causes the beginning and end of the wire to lift simultaneously, pushing the flexible push plate 147 to clamp and position the wire from its beginning, end, and middle ends. After the wire is clamped and positioned, the third cylinder 141 is activated, causing its extension end to drive the guide block 142. The wire slides along the inner wall of the second guide groove 13. At this time, the cutter 143 at the bottom of the guide block 142 will move synchronously, causing the cutter 143 to peel off the coating of the wire. The peeled wire, driven by the first conveying body 11, moves in a straight line. When the first conveying body 11 turns from top to bottom at a turning point in its straight line movement, the first counterweight 1491, due to its own weight, falls along the inner wall of the first slide groove 148 because the top opening of the first wire groove 144 is at the lower end after the turn. Simultaneously, the first counterweight 1491 drives the first... Spring 1492 is compressed, and simultaneously, the outer wall of the first push rod 1493 extends from the inner cavity of the first square groove 145 to the inner cavity of the first wire groove 144 under the fall of the first counterweight 1491. At this time, the wire stripped from the inner cavity of the first wire groove 144 will be pushed out of the inner cavity of the first wire groove 144 by the top of the first push rod 1493, so that the movable assembly composed of the three sets of ejector parts 149 and the first slide groove 148 corresponds to the middle end, end end and beginning end of the wire respectively. At the same time, after the wire is pushed out of the inner cavity of the first wire groove 144, the middle end of the diaphragm spring 146 is reset due to the elastic force. Then, the beginning end and end of the diaphragm spring 146 are synchronously driven without the push of the middle end. The push plate 147 is reset to allow for clamping and positioning of the wire again. The ejected wire will then be guided by the right-side plate 4 located at the corner of the first conveyor body 11 to the gap between the right-side plate 4 and the partition 2. The wire can then be clamped at the gap through the window 6 to perform the next work operation. At the same time, when the first wire groove 144 is reset from the lower end to the upper end by the drive of the first conveyor body 11, the first counterweight 1491 will be reset by the rebound of the first spring 1492. This will cause the first push rod 1493 to retract into the inner cavity of the first square groove 145 due to the reset of the first counterweight 1491, thus preparing for the next ejection.

[0036] In a preferred embodiment: the mounting assembly 22 includes a second placement box 221 fixedly mounted on the outer wall of the second conveying body 21. The inner wall of the second placement box 221 is provided with a second wire groove 222, a circular groove 223, and a second square groove 226. A resistor body 224 is disposed within the cavity of the second placement box 221. A ball groove 225 is formed on the inner wall of the resistor body 224. A second sliding groove 227 is formed on the inner wall of the second square groove 226. A sensor light 228 is disposed on the top of the second placement box 221. A mounting member 229 is disposed within the cavity of the second placement box 221. The mounting member 229 includes a... A second counterweight 2291 is placed inside the second square groove 226. A second spring 2292 is provided on the top of the second counterweight 2291. A second push rod 2293 is fixedly mounted on the top of the second counterweight 2291. A convex pin 2294 and a third spring 2299 are respectively provided inside the circular groove 223. One end of the third push rod 2295 is fixedly installed on the outer wall of the convex pin 2294. A striker 2297 is fixedly installed on the other end of the third push rod 2295. An annular gasket 2296 is fixedly installed on the inner wall of the circular groove 223. A sensor switch 2298 is provided on the inner wall of the circular groove 223.

[0037] In a preferred embodiment: the bottom of the resistor body 224 is sloped, and the outer wall of the slope is slidably fitted against the outer wall of the convex pin 2294. The circular groove 223, the ball groove 225, the sensor lamp 228, the convex pin 2294, the third push rod 2295, the annular washer 2296, the striker 2297, the sensor switch 2298, and the third spring 2299 are considered as a set of movable components, and there are two sets of such movable components, which are symmetrically arranged with the resistor body 224 as the center. One end of the two convex pins 2294 is spherical and is adapted to the shape of the inner wall of the ball groove 225. The outer wall of the other end of the two convex pins 2294 is slidably fitted against the inner wall of the circular groove 223. The two third springs 2299 are located at the middle of the convex pin 2294 and the annular washer 2296. One end of the second spring 2292 is connected to the outer wall of the convex pin 2294, and the other end is connected to the outer wall of the annular gasket 2296. The outer walls of the two third push rods 2295 are connected to the inner wall of the annular gasket 2296. The two sensor switches 2298 are located on one side of the striker 2297 and are electrically connected to the two sensor lights 228. The outer wall of the second counterweight 2291 is slidably attached to the inner wall of the second slide groove 227. One end of the second spring 2292 is connected to the top of the second counterweight 2291, and the other end is connected to the inner wall of the second square groove 226. The top of the second push rod 2293 is located at the bottom of the resistor body 224, and the outer wall of the second push rod 2293 is connected to the inner wall of the second placement box 221. The sensor lights 228 and the industrial camera 9 are horizontally aligned in the longitudinal direction.

[0038] In the above structure, by first inserting the resistor body 224 into the inner cavity of the second placement box 221, since the bottom of the resistor body 224 is inclined, the inclined surface will first contact the outer wall of the convex pin 2294 with one end spherical, thereby squeezing the convex pin 2294 and causing the other end of the convex pin 2294 to slide along the inner wall of the circular groove 223. At this time, the sliding convex pin 2294 will drive the third push rod 2295, which is fixed to it, to slide through the inner wall of the annular pad 2296. At the same time, the third spring 2299 provided on one side of the convex pin 2294 will slide and compress, thereby causing the other end of the annular pad 2296 to drive the striker 2297 to move closer to the sensor switch 2298, so that the striker 2297... When contact is made with sensor switch 2298, sensor switch 2298 is activated, causing sensor light 228 to emit a green light. At this time, after resistor body 224 is fully inserted into the inner cavity of second placement box 221, its convex pin 2294 will align with ball groove 225, causing convex pin 2294 to be reset by the rebound of third spring 2299, thereby inserting into the inner cavity of ball groove 225 to fix resistor body 224. At this time, circular groove 223 will disengage from sensor switch 2298, so that sensor light 228 will still emit a green light to capture information when passing industrial camera 9. Next, after the stripped wire is placed into the inner cavity of second wire groove 222, the wire and resistor body 224 are assembled. The connection point is pressed together by the wire pressing assembly 24, and then the connection point is spot welded together by the spot welding body 23. At this time, the wire and the resistor body 224 are in the assembled state. When the second conveying body 21 transports the second placement box 221 to its corner, the second placement box 221 turns from top to bottom. At this time, the second counterweight 2291 located in the inner cavity of the second square groove 226 will slide down the inner wall of the second slide groove 227 to the other end due to its own weight. The second spring 2292 set on the top of the second counterweight 2291 will be compressed due to the fall of the second counterweight 2291. At the same time, the second push rod 2293 set on the top of the second counterweight 2291 will extend out due to the sliding of the second counterweight 2291. The inner cavity of the square slot 226, due to the alignment of the top of the second push rod 2293 with the position of the resistor body 224, causes the resistor body 224 to exit the inner cavity of the second placement box 221 due to the push of the second push rod 2293. At this time, the convex pin 2294, the third push rod 2295, the third spring 2299, the annular washer 2296, the striker 2297, and the sensor switch 2298, through the same operation described above, enable the striker 2297 to contact the sensor switch 2298 again. When it contacts the sensor switch 2298 again, it will activate the sensor light 228, turning its green light into red. This indicates that the resistor body 224 and the wire assembled in the inner cavity of the second placement box 221 will slide down to the top of the final platform 7 via the left guide plate 8.This allows workers to easily assemble terminals on the other end of the wire. Simultaneously, when the second placement box 221 rotates from downward to upward, its second counterweight 2291 is reset by the rebound of the second spring 2292. Then, the second push rod 2293 retracts into the inner cavity of the second square groove 226 as the second counterweight 2291 resets, facilitating reuse.

[0039] In a preferred embodiment: the pressure assembly 24 includes a fourth cylinder 241 fixedly mounted on the outer wall of the baffle 20, a fisheye connector 242 is provided at the telescopic end of the fourth cylinder 241, a connecting plate 243 is rotatably connected to the top of the fisheye connector 242, a base 244 is fixedly mounted on the top of the baffle 20, a lever 245 is rotatably connected to the inner wall of the base 244, and a pressing head 246 is provided on the outer wall of the lever 245;

[0040] In a preferred embodiment: the cross-section of the lever 245 is inclined, and one end of the inclined surface is rotatably connected to the outer wall of the connecting plate 243, and the other end is fixedly connected to the pressing head 246 with the base 244 as the fulcrum. The pressing head 246 is located at the top of the connection between the resistor body 224 and the wire.

[0041] In the above structure, after the industrial camera 9 detects the red information of the sensor light 228, it controls the activation of the fourth cylinder 241 via a sensor. This causes the extension end of the fourth cylinder 241 to move the fisheye connector 242 upwards. The upwardly moving fisheye connector 242, through its connected connecting plate 243, pulls one end of the lever 245 upwards. Since the cross-section of the lever 245 is inclined and uses the base 244 as a fulcrum, when one end of the lever 245 is pushed, the other end rotates along the base 244, causing it to move upwards. The pressing head 246 moves downward. Since the pressing head 246 is located at the top of the connection between the resistor body 224 and the wire, its downward movement can apply pressure to the connection between the resistor body 224 and the wire, pressing the two tightly together, enhancing the firmness of the connection and preventing loosening during subsequent use. Secondly, when the fisheye connector 242 and the lever 245 move downward through the telescopic end of the fourth cylinder 241, the pressing head 246 moves upward, and the pressing head moves away after being pressed, so as to press the connection between the next set of resistor bodies 224 and the wire.

[0042] Working principle: First, the wire is placed into the first wire groove 144 inside the first placement box 12. During the wire insertion process, two sets of bow-shaped diaphragm springs 146 with inclined tops play a guiding role, guiding the wire smoothly into the first wire groove 144. At the same time, the protruding structure at the middle of the first wire groove 144 is pushed to both sides under the pressure of the wire, causing the first and last ends of the diaphragm springs 146 to tilt up, thereby pushing the flexible push plate 147 to clamp and position the wire from the first, last, and middle ends, preventing the wire from shifting during the stripping process. After the wire is positioned, the third cylinder 141 is activated, and its telescopic end drives the guide block 142 to slide along the inner wall of the second guide groove 13. The cutter 143 fixed at the bottom of the guide block 142 moves synchronously, so that the cutter 143 corresponds to the first wire groove 144. During the movement, the insulation of the wire is cut open, exposing the wire core. At this time, after the stripping is completed, the first conveying body 11 continues to drive, driving the first placement box 12. 2. Move to the corner position. At this time, the first placement box 12 turns from the upper end to the lower end. Due to gravity, the first counterweight 1491 in the inner cavity of the first square groove 145 falls along the inner wall of the first sliding groove 148. During the fall, the first spring 1492 is compressed, and at the same time, the first push rod 1493 extends from the inner cavity of the first square groove 145 to the inner cavity of the first wire groove 144, pushing the stripped wire out of the inner cavity of the first wire groove 144, so that the stripped wire is guided through the right side plate 4 to the space between the right side plate 4 and the partition 2. At the gap, waiting for subsequent grabbing, the diaphragm spring 146 resets under its own elastic force, driving the flexible push plate 147 back to its initial state, preparing for the next step of wire clamping, so that the first conveying body 11 continues to transmit, the first placement box 12 resets from the lower end to the upper end under the drive of the first conveying body 11, so that the first counterweight 1491 resets under the rebound of the first spring 1492, and the first push rod 1493 retracts into the inner cavity of the first square groove 145, thereby completing the reset of the wire stripping assembly 14;

[0043] Next, when the resistor body 224 is inserted into the inner cavity of the second placement box 221, since the bottom of the resistor body 224 is inclined, its inclined surface first contacts the spherical end of the convex pin 2294 and squeezes the convex pin 2294 to slide along the inner wall of the circular groove 223. During the sliding of the convex pin 2294, it drives the third push rod 2295 fixed thereto to slide through the inner wall of the annular gasket 2296, and at the same time compresses the third spring 2299, so that the striker 2297 at the other end of the third push rod 2295 moves with the convex pin 2294. When the striker 2297 contacts the sensor switch 2298, the sensor switch 2298... Triggering the system, the sensor light 228 illuminates green, indicating that the resistor body 224 is being installed. Once the resistor body 224 is fully inserted into the inner cavity of the second placement box 221, its convex pin 2294 aligns with the ball groove 225 on the inner wall of the resistor body 224. The convex pin 2294 is then reset by the return action of the third spring 2299, with one spherical end inserted into the inner cavity of the ball groove 225, thus securing the base 244. At this time, the convex pin 2294 drives the third push rod 2295 and the striker 2297 to reset, disengaging the striker 2297 from the sensor switch 2298. The sensor light 228 remains green during this time, facilitating subsequent industrial processes. Camera 9 detects and provides a signal, then activates the first cylinder 10 to drive the slider 15 to slide along the inner wall of the first guide groove 3, causing it to move the second cylinder 16, mounting plate 17, rotary cylinder 18, and gripper body 19 together to the wire gripping position at the gap between the right-side plate 4 and partition 2. Subsequently, the rotary cylinder 18 is activated, causing the gripper body 19 to rotate 90 degrees to the right, aligning the gripper body 19 with the stripped wire, so that the gripper body 19 closes to grip one end of the wire. The other set of moving components grips the other end of the wire in the same operation, causing both sets of moving components to simultaneously activate the rotary cylinder 18, moving the gripper body 19 and the gripped wire from the right... Rotate 90 degrees to the left to adjust the wire posture. Then, the first cylinder 10 drives the slider 15 to retract the entire assembly until the wire corresponds to the second wire groove 222 in the inner cavity of the second placement box 221. Subsequently, the second cylinder 16 is activated, and its extension end drives the mounting plate 17, the rotary cylinder 18, the gripper body 19 and the wire to move downward. When the wire reaches the top of the second wire groove 222, the gripper body 19 is released, and the wire is placed in the inner cavity of the second wire groove 222, realizing the initial docking of the wire with the resistor body 224. Then, the second conveying body 21 is activated, driving the second placement box 221 to move towards the wire pressing assembly 24.

[0044] When the second placement box 221 moves below the wire pressing assembly 24, the industrial camera 9 captures the red light signal of the sensor 228, determining that the resistor body 224 and the wire have been initially connected. The industrial camera 9 then activates the fourth cylinder 241 via a sensor, causing the extension end of the fourth cylinder 241 to move the fisheye connector 242 upwards. This upward movement of the fisheye connector 242, through its connected connecting plate 243, pulls one end of the lever 245 upwards. Since the cross-section of the lever 245 is inclined and uses the base 244 as a fulcrum, when one end of the lever 245 is... When pushed, the other end of the base 244 rotates and drives the pressing head 246 to move downward. Since the pressing head 246 is located at the top of the connection between the resistor body 224 and the wire, its downward movement can apply pressure to the connection between the resistor body 224 and the wire, pressing the two tightly together, enhancing the firmness of the connection and preventing loosening during subsequent use. Secondly, when the fisheye connector 242 and the lever 245 move downward through the telescopic end of the fourth cylinder 241, the pressing head 246 moves upward, and the pressing head moves away after being pressed, so as to press the connection between the next set of resistor bodies 224 and the wire.

[0045] Simultaneously, the second conveying body 21 continues to move the pressed resistor body 224 and the wire towards the spot welding body 23. When the connection reaches below the spot welding body 23, the spot welding body 23 is activated. According to the preset welding parameters, spot welding is performed on the pressed connection between the resistor body 224 and the wire. During the spot welding process, the high temperature causes the wire core and the connection end of the resistor body 224 to fuse together, forming a stable welding point, thus completely achieving the fixed assembly of the two. After the spot welding is completed, the second conveying body 21 moves the second placement box 221 to the corner position. After the second placement box 221 moves to the corner position, it turns from the upper end to the lower end. Under the action of gravity, the second counterweight 2291 in the inner cavity of the second square groove 226 falls along the inner wall of the second slide groove 227, compressing the second spring 2292. At the same time, it drives the second push rod 2293 to extend from the inner cavity of the second square groove 226 to the inner cavity of the second placement box 221, pushing the assembly complete. The resistor body 224 and the wire exit the inner cavity of the second placement box 221. During this process, the convex pin 2294 is squeezed and slid, which drives the third push rod 2295 and the striker 2297 to move, so that the striker 2297 contacts the sensor switch 2298 again, causing the sensor light 228 to switch from green to red, indicating that the finished product has been ejected. The finished product is guided by the left guide plate 8 and slides to the top of the final platform 7, waiting for the worker to assemble the other end of the wire with terminals. Next, the second conveying body 21 drives the second placement box 221 to reset from the lower end to the upper end, so that the second counterweight 2291 is reset under the rebound action of the second spring 2292, and the second push rod 2293 will retract into the inner cavity of the second square groove 226. At the same time, the convex pin 2294, the third push rod 2295, and the striker 2297 are reset under the action of the third spring 2299, so that the sensor light 228 returns to the red light state, thus preparing to enter the next round of assembly cycle. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
