Description

Technical Field

[0001] This invention relates to the field of automotive parts testing technology, specifically to a testing device for automotive handles. Background Technology

[0002] As a crucial component of the vehicle body, car door handles not only fulfill basic functions such as opening / closing doors and trunks, but are also key operational parts for occupants to escape in emergencies (such as when the vehicle falls into water or experiences electrical failure). Their functional stability directly impacts life safety. With the continuous improvement of automotive safety regulations, various countries and regions have successively introduced mandatory standards for vehicle emergency unlocking systems. According to the draft for comments on the mandatory national standard "Safety Technical Requirements for Automobile Door Handles" released by the Ministry of Industry and Information Technology in September 2025, the new regulations require that exterior door handles must retain a hand operating space of no less than 60 mm in length, 20 mm in width, and 25 mm in depth in any state, and must be equipped with a mechanical release function to ensure that the door can be manually opened after a power outage. This ensures that even in extreme scenarios such as vehicle power failure or electronic component malfunction, occupants can still unlock and escape through mechanical operation.

[0003] Against this backdrop, the mechanical unlocking performance testing of car handle assemblies (including the handle body, external cable, and end unlocking head) has become an indispensable quality control step in the automobile production process. Existing car handles include traditional mechanical, hidden pop-out, hidden rotating, hidden flip-in, semi-hidden, and handle-less types. Under the new regulations, hidden pop-out and handle-less types will be phased out, and the remaining types of car handles need to ensure operability and safety.

[0004] Currently, the industry's testing of the mechanical unlocking performance of car handles still relies primarily on manual inspection, supplemented by random sampling and special inspections. This approach has several insurmountable drawbacks: First, the consistency of manual inspection results is poor, failing to meet the precise quality control requirements of mass production, while random sampling and special inspections cannot guarantee that all produced car handles meet safety standards. Second, the testing efficiency is low, making it difficult to match the high-paced production rhythm of modern production lines. Third, there is a lack of data traceability capabilities; manually recorded test data is prone to errors and omissions, and it is difficult to link with the production management system, making it impossible to achieve full lifecycle traceability of product quality and source analysis of problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a detection device for automobile handles.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a detection device for car handles, including an outer frame and a conveying mechanism. The front and rear ends of the conveying mechanism are connected to the workshop conveying equipment. A positioning mechanism is provided inside the outer frame. A visual detector, a cable management mechanism and a detection mechanism are arranged in sequence in the conveying direction inside the outer frame. The positioning mechanism is located on the lower side of the detection mechanism. The detection mechanism includes a fixed frame and a positioning mechanism. A liftable baffle is provided on the rear side of the fixed frame. A lifting platform for driving the positioning mechanism to move up and down and laterally is provided on the inner side of the fixed frame. A gripping mechanism is provided on the positioning mechanism. The handle assembly is transported to the interior of the outer frame via the conveying mechanism. The cable management mechanism pushes the outer cable of the handle assembly to one side. After being blocked by the baffle, the positioning mechanism straightens the handle assembly housing. Then, the positioning mechanism of the detection mechanism moves with the lifting platform. After the positioning mechanism positions the handle assembly, the gripping mechanism lifts the handle. The vision detector detects the displacement distance of the unlocking head at the end of the outer cable.

[0007] As an improvement: the positioning mechanism includes a third cylinder and a moving platform. The third cylinder drives the gripping mechanism to move up and down inside the moving platform. A second cylinder is provided on the fixed frame. The second cylinder drives the lifting platform to move up and down inside the fixed frame. A second motor and a sliding rod are provided on the lifting platform. A threaded rod is provided at the output end of the second motor. A threaded hole that mates with the threaded rod and a guide hole that slides with the sliding rod are provided on the moving platform.

[0008] As an improvement: the gripping mechanism includes a lifting plate, a third motor, an arc-shaped plate and an outer cover. The lifting plate is connected to the outer cover, the output end of the third cylinder is connected to the outer cover, the third motor is located inside the outer cover, the lifting plate is provided with side plates and through slots, the third motor drives the arc-shaped plate to rotate between the side plates, one end of the arc-shaped plate is provided with a lifting claw that can extend out of the through slot, and pressure sensors are provided at the end and inside of the lifting claw.

[0009] As an improvement: the bottom of the mobile platform is provided with a mounting plate, and the mounting plate is provided with multiple positioning components, including an adjusting rod and a positioning rod. The adjusting rod is hinged to the side of the mounting plate and fastened with nuts. The positioning rod is installed at the end of the adjusting rod by two nuts. When detecting the hidden rotating handle, a pressure rod is installed at the bottom of the mounting plate.

[0010] As an improvement: the conveying mechanism includes a conveyor belt, a cross frame, a swing frame, a cylinder, a drive roller, a guide roller, a swing roller, and a motor. One end of the cross frame is hinged to the swing frame. The drive roller and the guide roller are rotatably mounted on the cross frame. The swing roller is rotatably mounted on the swing frame. The conveyor belt is mounted on the drive roller, the guide roller, and the swing roller. The motor drives the drive roller to rotate the conveyor belt. The cylinder is hinged inside the outer frame. The output end of the cylinder is hinged to the swing frame.

[0011] As an improvement: a wire plate for placing external wires is provided on one side of the cross frame, a side baffle is provided on the outside of the wire plate, a background platform for placing the unlocking head is provided near the material input end of the wire plate, and a vision detector is located above the background platform.

[0012] As an improvement: the cable management mechanism includes a stand, a trough plate, a motor, and pulleys. The two ends of the stand are connected to the trough plate and the outer frame respectively. Two pulleys are rotatably located inside the trough plate. The output end of the motor is connected to one of the pulleys. The two pulleys are connected by belt drive. Multiple rubber strips are evenly distributed on the outer side of the belt.

[0013] As an improvement: the positioning mechanism includes multiple fixed rods, each fixed rod is equipped with a cylinder four, the output end of the cylinder four is equipped with a positioning push platform, and the positioning push platform is equipped with a groove that matches the shape of the selected point on the handle assembly housing.

[0014] The advantages of this invention compared to existing technologies are as follows: This invention achieves full-process automation of automotive handle assembly inspection through the collaborative design of the outer frame, conveying mechanism, visual detector, cable management mechanism, placement mechanism, and inspection mechanism. This effectively solves the problems of high reliance on manual labor, low accuracy, and slow efficiency in existing inspection methods. It meets the stringent inspection requirements of new regulations for the mechanical unlocking function of automotive handles, providing a stable, accurate, and efficient quality control solution for automotive production lines. Simultaneously, it is adaptable to the inspection of various handle specifications, significantly improving inspection versatility and data traceability capabilities, while reducing labor costs and material waste. Specifically: 1. The entire process of conveying, cable management, placement, positioning, gripping, and inspection of the handle assembly can be completed without manual intervention. The visual detector accurately measures the displacement distance of the unlocking head, and the pressure sensor of the gripping mechanism monitors the operating force in real time, avoiding subjective human error. The inspection accuracy is greatly improved compared to manual methods, ensuring that the inspection results meet the regulatory standards and production quality requirements. It can be adapted to the high-speed production rhythm of modern production lines, eliminate bottlenecks in the inspection process, and ensure the continuity of mass production. 2. The adjusting rod and positioning rod of the positioning mechanism can be flexibly adjusted in angle and height. When testing hidden rotating handles, only the pressure rod needs to be installed. There is no need to replace the entire testing component. It can be compatible with the testing of various specifications of handle assemblies such as traditional mechanical, hidden rotating, hidden inward flip, and semi-hidden, reducing equipment replacement and matching costs. 3. The cable management mechanism uses soft rubber strips to comb the outer cables and prevent damage; the gripping mechanism uses pressure sensors to control the gripping force to prevent the handle from deforming or being damaged; the conveying mechanism can automatically sort out unqualified products, reducing the risk of manual contact. At the same time, each mechanism uses guide grooves, slide bars and other components to limit the movement trajectory, ensuring stable operation and reducing the probability of equipment failure. 4. During the testing process, key data such as the displacement of the unlocking head and the operating force are automatically recorded, which facilitates linkage with the production management system and enables full life-cycle traceability of product quality. When an abnormality occurs during testing, the problematic batch and cause can be quickly located, providing data support for production line quality improvement and reducing the risk of unqualified products entering the market.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 6 and attached Figure 11 As shown, a detection device for car handles includes an outer frame 1 and a conveying mechanism 2. The conveying mechanism 2 is connected to the workshop conveying equipment at both ends. A positioning mechanism 7 is provided inside the outer frame 1. The outer frame 1 contains a visual detector 8, a cable management mechanism 9, and a detection mechanism 3 arranged sequentially in the conveying direction. The positioning mechanism 7 is located on the lower side of the detection mechanism 3. The detection mechanism 3 includes a fixing frame 4 and a positioning mechanism 5. A liftable baffle 46 is provided on the rear side of the fixing frame 4. The driving positioning mechanism 5 is provided on the inner side of the fixing frame 4 for lifting and lateral movement. The lifting platform 42 and the positioning mechanism 5 are equipped with a gripping mechanism 6. The handle assembly 00 is transported to the outer frame 1 via the conveying mechanism 2. The cable management mechanism 9 pushes the outer cable 02 of the handle assembly 00 to one side. After being blocked by the baffle 46, the positioning mechanism 7 straightens the handle assembly 00 housing. Then, the positioning mechanism 5 of the detection mechanism 3 moves with the lifting platform 42. After the positioning mechanism 5 positions the handle assembly 00, the gripping mechanism 6 lifts the handle 01. The vision detector 8 detects the displacement distance of the unlocking head 03 at the end of the outer cable 02.

[0030] This car handle detection device solves problems such as poor universality of handle detection, delivery and positioning deviation, lack of cable management ability for external wires 02, and adaptability and stability of gripping and detection during the detection process of car handle assembly 00 through the coordinated cooperation of various mechanisms. It achieves accurate detection of the force required for the action of handle 01 and the action of the unlocking head 03 at the end of the external wire 02 of handle assembly 00.

[0031] After the car handle detection device is started, the handle assembly 00 is first transported to the docking position with the input end of the conveyor mechanism 2 via the workshop conveyor equipment. Then, the conveyor mechanism 2 smoothly transports the handle assembly 00 to the detection area inside the outer frame 1. During the movement of the handle assembly 00 with the conveyor mechanism 2, the cable management mechanism first sorts out the outer wires 02 on the handle assembly 00 and pushes them to one side to facilitate the subsequent placement of the unlocking head 03 in the detection area of ​​the vision detector 8. When the handle assembly 00 is transported to the preset position corresponding to the detection mechanism 3, the baffle 46 on the rear side of the fixing frame 4 will descend with the lifting platform 42 to block the handle assembly 00 and stop its movement. At this time, the conveyor mechanism 2 stops. Then, the positioning mechanism 7 starts to work to adjust the position of the housing of the handle assembly 00, straighten any housing that may be offset, and ensure that the overall position of the handle assembly 00 meets the requirements of subsequent positioning and detection.

[0032] After the positioning is completed, the lifting platform 42 in the detection mechanism 3 starts to descend again, driving the positioning mechanism 5 to move up, down and laterally according to the actual position of the handle assembly 00, so that the positioning mechanism 5 accurately fits the handle assembly 00. After the positioning operation is completed, the gripping mechanism 6 moves the handle 01 in the handle assembly 00 (pulling outward or pushing inward). At this time, the handle 01 drives the unlocking head 03 through the steel wire inside the outer wire 02. Finally, the vision detector 8 starts the detection program to accurately detect the displacement distance of the unlocking head 03 and record the detection data, completing one detection process of the handle assembly 00. After the detection is completed, each mechanism resets, waiting for the next handle assembly 00 to enter the detection area.

[0033] Combined with appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 8 As shown, the positioning mechanism 5 includes a third cylinder 51 and a moving platform 52. The third cylinder 51 drives the gripping mechanism 6 to move up and down inside the moving platform 52. The fixed frame 4 is equipped with a second cylinder 41, which drives the lifting platform 42 to move up and down inside the fixed frame 4. The lifting platform 42 is equipped with a second motor 43 and a sliding rod 421. The output end of the second motor 43 is equipped with a threaded rod 44. The moving platform 52 is equipped with a threaded hole 521 that mates with the threaded rod 44 and a guide hole 522 that slides with the sliding rod 421.

[0034] Combined with appendix Figure 7As shown, the front end of the fixed frame 4 is provided with a proximity switch 45, the rear side of the fixed frame 4 is provided with a guide platform 47, the rear side of the lifting platform 42 is provided with an outer support rod 422, the outer support rod 422 is slidably engaged with the inner groove of the guide platform 47, the top of the baffle 46 is slidably engaged with the inner groove of the guide platform 47, and a spring 48 is connected between the outer support rod 422 and the top of the baffle 46.

[0035] The positioning mechanism 5 and the fixed frame 4 work together to solve problems such as insufficient lateral and longitudinal movement accuracy of the positioning mechanism 5, deviation of the lifting platform 42, lack of buffering in the limit of the baffle 46, and deviation of the gripping position of the handle 01, providing a precise and stable positioning and support foundation for the inspection of the handle assembly 00.

[0036] When the handle assembly 00 is transported to the preset area at the front end of the fixed frame 4 via the conveying mechanism 2, the proximity switch 45 at the front end of the fixed frame 4 first detects the handle assembly and then sends a signal to trigger subsequent actions. At this time, the baffle 46 in the inner groove of the guide platform 47 on the rear side of the fixed frame 4 moves downward under the action of the drive structure until it reaches the preset height, blocking the handle assembly 00 and stopping its movement. During this process, the cylinder 41 on the fixed frame 4 is activated, causing the lifting platform 42 to descend. The outer support rod 422 drives the top of the baffle 46 to slide smoothly along the inner groove of the guide platform 47 through the spring 48. At this time, the spring 48 between the outer support rod 422 and the top of the baffle 46 is in a natural state, preparing for subsequent buffering.

[0037] After the handle assembly 00 is positioned and the positioning mechanism 7 aligns the handle assembly 00 housing, the cylinder 41 on the fixed frame 4 is restarted, driving the lifting platform 42 to move downward along the fixed frame 4. The outer support rod 422 on the rear side of the lifting platform 42 slides synchronously along the inner groove of the guide plate 47, ensuring that the lifting platform 42 always moves smoothly along the preset trajectory. At the same time, the motor 43 on the lifting platform 42 is started, and the threaded rod 44 at its output end begins to rotate. Through cooperation with the threaded hole 521 on the moving platform 52, it drives the moving platform 52 to move laterally along the slide rod 421. The guide hole 522 of the moving platform 52 slides tightly with the slide rod 421, limiting the offset of the moving platform 52, so that the positioning mechanism 5 moves accurately to directly above the handle assembly. During this process, as the lifting platform 42 descends, the spring 48 is compressed, giving the positioning mechanism 5 and the gripping mechanism 6 room to move.

[0038] After the positioning mechanism 5 is in place, cylinder 3 51 starts, driving the gripping mechanism 6 to move downward inside the moving platform 52 until the gripping mechanism 6 makes close contact with the handle 01 and completes the gripping. After the gripping is completed, cylinder 3 51 reverses its action, driving the gripping mechanism 6 to move upward and lift the handle. During this process, the gripping mechanism 6 detects the stroke and tension curve of the handle 01, and the positioning mechanism 7 detects the stroke of the handle 01 and the action curve of the unlocking head 03. After the detection is completed, cylinder 3 51 reverses its action again to drive the gripping mechanism 6 to lower the handle, motor 2 43 rotates in the opposite direction to drive the moving platform 52 to reset, cylinder 2 41 drives the lifting platform 42 to rise and reset, the outer support rod 422 rises with the lifting platform 42 and the spring 48 returns to its original state, and drives the baffle 46 to rise and reset. At this time, the conveying mechanism 2 starts, conveying the tested handle assembly 00 and conveying the next handle assembly 00 to the position, starting a new round of positioning and support process.

[0039] Combined with appendix Figure 8 and attached Figure 10 As shown, the gripping mechanism 6 includes a lifting plate 61, a motor 62, an arc-shaped plate 63, and an outer cover 64. The lifting plate 61 is connected to the outer cover 64, the output end of the cylinder 51 is connected to the outer cover 64, the motor 62 is located inside the outer cover 64, the lifting plate 61 is provided with a side plate 611 and a through groove 613, the output end of the motor 62 is provided with a gear 621, the arc-shaped plate 63 is provided with a ring tooth 634 that meshes with the gear 621, the outer side of the arc-shaped plate 63 is provided with an arc-shaped slide table 633, the side plate 611 is provided with an arc-shaped slide groove 612 that slides with the arc-shaped slide table 633, one end of the arc-shaped plate 63 is provided with a lifting claw 631 that can extend out of the through groove 613, and pressure sensors 632 are provided at both the end and the inner side of the lifting claw 631.

[0040] The gripping mechanism 6, through the coordinated design of its components, addresses key issues such as gripping angle deviation, improper force control leading to handle damage, insufficient stability after gripping, and inability to monitor the gripping status in real time. This ensures accurate and stable gripping of the handle 01 in the handle assembly 00, providing a reliable guarantee for the subsequent displacement detection of the unlocking head 03.

[0041] When the moving platform 52 of the positioning mechanism 5 drives the gripping mechanism 6 to move precisely above the handle 01, the cylinder 3 51 starts, and its output end pushes the outer cover 64 to move downward. The outer cover 64 drives the lifting plate 61 connected to it to descend synchronously, so that the gripping mechanism moves closer to the handle 01 until it reaches the preset gripping position. At this time, the cylinder 3 51 stops moving, and the gripping mechanism is in the ready-to-grip state. Subsequently, the motor 3 62 inside the outer cover 64 starts, and its output end drives the gear 621 to rotate. Since the gear 621 meshes with the ring tooth 634 of the arc plate 63, the rotation of the gear 621 drives the arc plate 63 to rotate along the arc groove 612 of the side plate 611 of the lifting plate 61. During this process, the arc slide 633 on the outer side of the arc plate 63 slides smoothly along the arc groove 612, providing guidance for the rotation of the arc plate 63 and preventing the arc plate 63 from deviating.

[0042] As the arc plate 63 rotates, the lifting claw 631 at one end gradually extends out of the through groove 613 of the lifting plate 61 and fits against the inner contour of the handle 01. After the pressure sensor 632 at the end of the lifting claw 631 contacts the inner side of the handle 01, the rotation of the arc plate 63 stops. At this time, the lifting claw 631 has firmly and undamagedly locked the handle 01, completing the gripping action. After the gripping is completed, the cylinder 51 moves in the opposite direction, and its output end pulls the outer cover 64, causing the lifting plate 61 and the gripped handle 01 to move upward. The pressure sensor 632 on the inner side of the lifting claw 631 stops the rotation of the arc plate 63. During the lifting process of the handle 01, the pressure value of the lifting claw in contact with the handle 01 is monitored in real time. When the pressure sensor 632 detects that the pressure value reaches the preset safe gripping range, the sensor sends a signal to the control system, and the control system then controls the cylinder 3 51 to stop rotating. During this process, the pressure sensor 632 on the inside of the lifting claw 631 continuously monitors the pressure value. If an abnormal pressure occurs within the reasonable lifting stroke of the lifting claw 631 (such as the pressure drop caused by the handle loosening or the pressure rise caused by jamming), an alarm signal is issued, indicating that there is a problem with the handle assembly 00.

[0043] After the displacement detection of the unlocking head 03 is completed, cylinder 3 51 drives the gripping mechanism 6 to descend and reset to the gripping position. Motor 3 62 rotates in the opposite direction, driving gear 621 to drive the arc plate 63 to rotate in the opposite direction. The lifting claw 631 gradually retracts into the through groove 613, disengaging from the handle 01. Cylinder 3 51 restarts, driving the gripping mechanism 6 to reset, waiting for the next time to cooperate with the positioning mechanism 5 to complete a new handle gripping action.

[0044] Combined with appendix Figure 9As shown, the bottom of the moving platform 52 is provided with a mounting plate 53, and the mounting plate 53 is provided with a plurality of positioning components 55. The positioning component 55 includes an adjusting rod 551 and a positioning rod 552. The adjusting rod 551 is hinged to the side of the mounting plate 53 and fastened with nuts. The positioning rod 552 is installed at the end of the adjusting rod 551 by two nuts. When the hidden rotating handle 01 is detected, a pressure rod 54 is installed at the bottom of the mounting plate 53.

[0045] The positioning component 55, through the combination design of the adjusting rod 551 and the positioning rod 552, mainly solves the problems that traditional positioning structures cannot adapt to handle assemblies 00 of different specifications and shapes, and that the fixed positioning position leads to deviation, providing accurate and flexible positioning support for handle testing.

[0046] Before conducting routine handle 01 testing, the positioning component 55 needs to be adjusted according to the model of handle assembly 00: First, loosen the nut connecting the adjusting rod 551 to the side of the mounting plate 53, rotate the adjusting rod 551 around the hinge point to a position that matches the positioning point of the handle assembly 00 housing, ensuring that the positioning rod 552 can accurately fit the positioning point of the handle assembly 00 housing. After the angle adjustment is completed, tighten the nut to lock the position of the adjusting rod 551. Next, loosen the nuts on the upper and lower sides of the positioning rod 552, and according to the height of handle 01, move the positioning rod 552 up and down along the mounting hole at the end of the adjusting rod 551 so that the end of the positioning rod 552 just contacts the preset positioning point of the handle assembly 00. After the height adjustment is completed, tighten the nuts on the upper and lower sides of the positioning rod 552 respectively to fix the height of the positioning rod 552, completing the preliminary debugging of the positioning component 55.

[0047] When the moving platform 52 moves the mounting plate 53 and positioning component 55 to the corresponding position of the handle assembly 00 along with the lifting platform 42, the positioning rod 552 of the positioning component 55 first contacts the positioning point of the handle assembly 00. When testing the traditional mechanical, hidden flip-up, and semi-hidden handles 01, there is no need to install the pressure rod 54. After the positioning component 55 completes the positioning, the handle 01 is opened by the gripping mechanism 6. If the hidden rotating handle 01 is being tested, after the positioning component 55 completes the positioning, the pressure rod 54 at the bottom of the mounting plate 53 will move towards the pressing point of the handle 01 until the pressure rod 54 presses up the other end of the hidden rotating handle 01, causing the hidden rotating handle 01 to rotate open.

[0048] During the process of gripping the handle 01 by the gripping mechanism 6 and driving the handle 01 to rise and fall for testing, the positioning component 55 always maintains stable contact with the positioning point of the handle assembly 00. After the displacement detection of the unlocking head 03 is completed, the gripping mechanism 6 lowers the handle 01, and the moving table 52 drives the mounting plate 53 and the positioning component 55 to reset with the lifting table 42. If the specifications of the handle 01 to be tested later change, the above adjustment steps can be repeated to adjust the angle and height of the positioning component 55, or the pressure rod 54 can be installed or removed as needed to adapt to the testing of the new specifications of the handle.

[0049] Combined with appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the conveying mechanism 2 includes a conveyor belt 21, a cross frame 22, a swing frame 23, a cylinder 24, a drive roller 25, a guide roller 26, a swing roller 27, and a motor 28. One end of the cross frame 22 is hinged to the swing frame 23. The drive roller 25 and the guide roller 26 are rotatably mounted on the cross frame 22, and the swing roller 27 is rotatably mounted on the swing frame 23. The conveyor belt 21 is mounted on the drive roller 25, the guide roller 26, and the swing roller 27. The motor 28 drives the drive roller 25 to rotate the conveyor belt 21. The cylinder 24 is hinged inside the outer frame 1, and the output end of the cylinder 24 is hinged to the swing frame 23. When the swing frame 23 is horizontal, it cooperates with the workshop conveying equipment to complete the material conveying. When the swing frame 23 is in an inclined state, it conveys the material to the waste collection box.

[0050] Combined with appendix Figure 3 and attached Figure 4 As shown, a wire plate 221 for placing the outer wire 02 is provided on one side of the cross frame 22. A side baffle 222 is provided on the outer side of the wire plate 221. A background platform 223 for placing the unlocking head 03 is provided near the material input end of the wire plate 221. The vision detector 8 is located above the background platform 223.

[0051] The conveying mechanism 2, through the collaborative design of multiple components, focuses on solving problems such as the inability of traditional conveying equipment to adapt to handle assemblies 00 of different heights, the disorderly arrangement of external wires 02 and unlocking heads 03 during the conveying process affecting detection, and insufficient conveying stability. It provides a stable and orderly guarantee for the transmission of handle assemblies 00 from the workshop conveying equipment to the detection area.

[0052] During the conveying process, motor 28 drives the drive roller 25 on the cross frame 22 to rotate, and the drive roller 25 drives the conveyor belt 21 to move. The conveyor belt 21 maintains a uniform and stable operation under the guidance of the guide roller 26 and the support of the swing roller 27. At this time, the handle assembly 00 is placed at the input end of the conveyor belt 21 (the position of the drive roller 25). After the handle assembly 00 enters the outer frame 1, the outer wire 02 of the handle assembly 00 is pushed onto the wire plate 221 on one side of the cross frame 22 by the wire management mechanism 9. Under the obstruction of the side stop bar 222, the outer wire 02 moves on the wire plate 221. The unlocking head 03 at the end of the outer wire 02 can move to the background platform 223 with the movement of the handle assembly 00, so that the unlocking head 03 is within the detection range of the vision detector 8.

[0053] Simultaneously, driven by the conveyor belt 21, the handle assembly 00 is smoothly transported to the inspection area. After the inspection is completed, the qualified handle assembly 00 is transported to the end of the conveyor belt 21 and transferred to the conveying equipment at the rear of the workshop. The unqualified handle assembly 00 will first be transported to the end of the conveyor belt 21 (leaving the interior of the outer frame 1), and then the cylinder 24 is activated. The output end of the cylinder 24 pulls the swing frame 23 to rotate around the hinge point with the cross frame 22. The swing frame 23 drives the swing roller 27 on it to rotate synchronously, so that the swing frame 23 tilts downward and transports the unqualified handle assembly 00 to the collection box below.

[0054] Combined with appendix Figure 2 and attached Figure 12 As shown, the cable management mechanism 9 includes a frame 91, a trough plate 92, a motor 93, and pulleys 94. The two ends of the frame 91 are connected to the trough plate 92 and the outer frame 1, respectively. Two pulleys 94 are rotatably located inside the trough plate 92. The output end of the motor 93 is connected to one of the pulleys 94. The two pulleys 94 are connected by a belt 95. Multiple rubber strips 96 are evenly arranged on the outer side of the belt 95.

[0055] The cable management mechanism 9, through the coordinated design of belt drive and rubber strips, focuses on solving problems such as messy placement of the outer cable 02 during the conveying of the handle assembly 00, easy damage to the outer cable 02 during cable management, and mismatch between cable management efficiency and conveying rhythm, thus providing a foundation for subsequent positioning and detection.

[0056] Before starting the entire testing device, the position of the cable management mechanism 9 needs to be adjusted according to the preset combing direction of the outer cable 02 of the handle assembly and the height of the conveyor belt 21 of the conveying mechanism 2. By connecting the upright 91 and the outer frame 1, the height and angle of the trough plate 92 are finely adjusted so that the belt 95 and rubber strip 96 on the inner side of the trough plate 92 can accurately correspond to the approximate position of the outer cable 02 of the handle assembly on the conveyor belt 21, ensuring that the rubber strip 96 can effectively contact the outer cable 02 during operation. After the adjustment is completed, the upright 91 is fixed to ensure the stability of the cable management mechanism.

[0057] When the conveyor belt 21 of the conveyor mechanism 2 drives the handle assembly 00 to move towards the detection area, and the handle assembly 00 is about to reach the bottom of the cable management mechanism 9, the motor 4 93 of the cable management mechanism 9 starts. The output end of the motor 4 93 drives the pulley 94 connected to it to rotate. The pulley 94 drives the pulley 94 on the other side to rotate synchronously through the belt 95, so that the belt 95 runs at a constant speed along the track inside the trough plate 92. The rubber strip 96 on the outside of the belt 95 moves synchronously with the belt and enters the cable management state.

[0058] As the conveyor belt 21 continues to transport, the disordered outer wires 02 of the handle assembly 00 gradually approach the operating rubber strip 96. The rubber strip 96 that first contacts the outer wires 02 uses its own softness and moderate friction to push the outer wires 02, which are off-center from the preset position, to the designated side. The subsequent continuously moving rubber strips 96 sort out the outer wires 02 in turn, further adjusting the placement of the outer wires 02, ensuring that the outer wires 02 are laid flat on the wire plate 221 on one side of the conveyor belt 21 along the preset direction, avoiding the outer wires 02 being messy and disorderly, and ensuring that the unlocking head 03 moves to the background table 223 and is within the detection range of the vision detector 8.

[0059] Combined with appendix Figure 11 As shown, the positioning mechanism 7 includes multiple fixed rods 71, and a cylinder 72 is provided on the fixed rod 71. The output end of the cylinder 72 is provided with a positioning push table 73, and the positioning push table 73 is provided with a groove that matches the shape of the selected point on the handle assembly housing 00.

[0060] The positioning mechanism 7 mainly solves the problem that after the handle assembly 00 is conveyed by the conveying mechanism 2 and the cable management mechanism 9, the housing is prone to positional deviation and angular skew, which makes it impossible for the subsequent detection mechanism 3 to accurately position and grasp it. It provides the detection mechanism 3 with a accurately positioned housing state.

[0061] Once the handle assembly 00, after cable management, is conveyed by the conveyor mechanism 2 to a preset position below the testing mechanism 3, and the baffle 46 stops the handle assembly from moving, the positioning mechanism 7 is activated. Multiple cylinders 72 on the fixing rods 71 ​​operate synchronously, pushing the positioning pusher 73 towards the handle assembly 00 housing until the pusher is in contact with the housing. Then, cylinders 72 apply thrust according to a preset stroke, causing the housing to move in the correct direction, correcting any offset or tilt, and positioning the housing in the standard position for the testing mechanism 3. After positioning, the positioning pusher 73 fixes the handle assembly 00, preventing displacement during the testing process. After testing, cylinders 72 reset the positioning pusher 73, awaiting the arrival of the next handle assembly 00. The entire process is synchronized with the action rhythm of the testing mechanism 3, ensuring efficient connection.

[0062] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
