The device includes a frame mechanism comprising a contour base and a product structure. The product structure includes a rear cover positioned above the contour base, a lamp holder mounted below the rear cover, and a dimming screw connecting the lamp holder and the rear cover in the middle. This device solves the problem of wire insulation wear, electrical connection stability, and safety issues caused by forcibly pulling the wire to maintain a taut state after assembling the wire and plug and closing the headlight cover. The device utilizes a connecting tube penetrating the plug and through-hole to provide a guiding foundation.

Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and more specifically, to an automatic assembly and re-inspection device for automotive lighting dimming modules and its assembly and re-inspection process. Background Technology

[0002] Vehicle lights are an indispensable and critical component of a vehicle, primarily responsible for functions such as driving illumination and signal warning. Their performance and stability are crucial to overall vehicle safety, directly impacting driving safety at night and in complex road conditions. The headlight dimming module, as the core control unit of the headlights, is mainly responsible for adjusting parameters such as the beam height and horizontal angle. It can dynamically adjust the beam range according to actual conditions such as vehicle load and road conditions, ensuring that the driver can clearly see the road while avoiding glare for oncoming vehicles. It is a vital component for improving driving safety.

[0003] Currently, in the assembly process, four wires are first manually threaded through the through holes in the headlight rear cover. Then, the headlight assembly and headlight rear cover are assembled, and the dimming module is fixed in the designated mounting position on the headlight housing. By pulling the wires, the plugs are brought in and inserted into the through holes. Then, the wires are pulled one by one to keep them taut, thus achieving wire lead-out and sealing fixation. After that, the assembly equipment is used to press the headlight rear cover and headlight assembly together, and the headlight angle is adjusted by driving the dimming bolt to achieve the standard.

[0004] Currently, during the assembly of wires and plugs, and the subsequent assembly of headlight covers, the plugs are inserted and fixed by manually pulling the wires, and then the wires are pulled taut one by one. However, when the headlights are assembled with the rear cover, the plugs exert a reverse squeezing force on the wires inside the rear cover, causing the originally taut wires to bend and deform. If the wires are forcibly pulled to maintain their tautness, the friction between the wires and the inner wall of the plugs will be further aggravated, which may cause wear on the wire insulation layer and affect the stability and safety of the electrical connection. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an automatic assembly and re-inspection device for vehicle headlight dimming modules and its assembly and re-inspection process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly and re-inspection device for vehicle headlight dimming modules, comprising a frame mechanism, wherein the frame mechanism includes a contouring seat.

[0012] The present invention is further configured such that: the pressing assembly includes a gantry frame and a lifting cylinder installed on the top of the base frame, a lifting frame is slidably connected to one side of the gantry frame, the top end of the piston rod of the lifting cylinder is connected to the lifting frame, a pressing adjustment mechanism is installed at the bottom of the lifting frame, and the driving assembly is installed below the pressing adjustment mechanism.

[0013] The present invention is further configured such that: the pressing adjustment mechanism includes two first columns symmetrically connected to the bottom of the lifting frame, and two second columns symmetrically connected to the top of the base frame, the two first columns and the two second columns being arranged correspondingly, and a pressure head is installed on one side of the bottom of the lifting frame, the pressure head being adapted to the top of the rear cover.

[0014] The bottom of the lifting frame is equipped with a bracket, and the bottom of the bracket is equipped with two positioning rods, which are correspondingly set with two mounting screws. The top of the bracket is equipped with a servo motor, the output end of which passes through the bottom of the bracket and is connected to a rotating head. The bottom of the rotating head has a screwing groove that corresponds to the top of the dimming screw. The drive assembly is installed at the bottom of the bracket.

[0015] The present invention is further configured such that: the wire assembly further includes a first tube body disposed inside the connecting tube, a second tube body is rotatably connected inside the first tube body via a bearing, a second cross spring plate is connected to the bottom end of the first tube body, and a first cross spring plate is connected to the outer wall of the bottom end of the first tube body.

[0016] The present invention is further configured such that: the driving assembly includes a fixed plate disposed below the bracket and a bearing plate disposed below the fixed plate; two first cylinders are symmetrically mounted on the top of the bearing plate; the piston rods of the two bearing plates are connected to the fixed plate; two guide rods are connected to the bottom of the fixed plate; the bottom of the guide rods extends to the bottom of the bearing plate and is connected to a mounting bracket; a sleeve is inserted through the middle of the mounting bracket; a rod is connected to the middle of the bottom surface of the fixed plate; the bottom end of the rod penetrates the bearing plate and extends into the inside of the sleeve.

[0017] The present invention is further configured such that: the diameter of the connecting pipe is smaller than the inner diameter of the sleeve; two protrusions are symmetrically connected to the inner sidewall of the sleeve; and two positioning grooves are symmetrically opened on the top of the outer wall of the connecting pipe, with the two positioning grooves corresponding to the two protrusions.

[0018] The top of the second tube is symmetrically connected to two blocks. The bottom of the rod is provided with a slot. The inner sidewall of the slot is symmetrically provided with two grooves and two placement slots. The two grooves and two placement slots are alternately arranged. The bottom of the groove is through. A cavity is provided inside the slot and above the grooves and placement slots. The top of the bracket is equipped with a second cylinder.

[0020] An automated assembly and re-inspection process for vehicle headlight dimming modules, using the automated assembly and re-inspection equipment for vehicle headlight dimming modules as described above, includes the following steps:

[0021] S1. Pass the wire assembly through the inside of the plug and use the wire assembly to help position the four wires, with the plug positioned close to the connector.

[0022] S2. Then connect the wire assembly to the drive assembly and use the drive assembly to control the wire assembly, causing the plug to be pulled upward, causing the plug to move upward along the outer wall of the four wires and be inserted into the through hole. Then the wire assembly removes the restriction on the wires and plug and moves out.

[0023] S3. Then, the pressing component squeezes the back cover and simultaneously screws the dimming screw, causing the angle of the lamp holder to change. The screwing angle is precisely controlled. After the dimming screw is screwed, the testing component detects the angle of the lamp holder to determine whether the product structure meets the standard. After the determination is completed, the staff removes the product structure and removes the wire assembly from below the drive component.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] (1) The connecting pipe provides a guide base through the plug and the through hole. The swing plate hinged linkage block extends and retracts along the through groove, so that the block extends and forms a stable force support point with the bottom of the plug. When the wire assembly is pulled, the plug can be moved up along the axis of the connecting pipe, which replaces the uncertain guidance method of manually pulling the wire, avoids the misalignment of the plug, and ensures the accuracy of the through hole sealing.

[0026] (2) By bringing the plug closer to the connector to shorten the wire length to less than the distance between the connector and the back cover, the redundant length of the wire is shortened, reducing bending deformation. At the same time, the component guides the plug to slide along the wire extension direction, reducing the relative friction coefficient between the two. This achieves the goal of reducing wire bending when the lamp holder and the back cover are combined, avoiding insulation wear, and ensuring electrical connection stability and safety.

[0027] (3) By setting the first cross spring plate, the second cross spring plate, the swing plate, the support block and the drive component of the wire assembly, and cooperating with the pressing adjustment mechanism and the test component, the cross spring plate clamps the wire to provide a reverse force, the drive component drives the plug to move, the servo motor precisely adjusts the dimming screw, and the infrared rangefinder detects the angle, thereby reducing the wire pulling strength, realizing the precise adjustment of the lamp holder angle and the rapid judgment of the product quality.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0052] Please see Figures 1-16 The present invention provides the following technical solutions:

[0053] Example 1, see Figure 1 and Figure 2 An automatic assembly and re-inspection device for vehicle headlight dimming modules includes a frame mechanism 1, which includes a contouring seat 12 and a base frame 11. The contouring seat 12 is installed on the top of the base frame 11, and a frame body 13 is also installed on the top of the base frame 11. The base frame 11 and the frame body 13 form the main body of the device. The contouring seat 12 is set on the top of the base frame 11 and is used to place the vehicle headlights for convenient subsequent assembly and re-inspection.

[0054] See Figure 3 , Figures 6-9 The product structure 4 is placed on top of the contour base 12. The product structure 4 includes a back cover 41 set above the contour base 12, a lamp holder 43 installed below the back cover 41, and a dimming screw 44 connecting the lamp holder 43 and the back cover 41 in the middle. The bottom of the lamp holder 43 is connected to a connector 48, and the top of the connector 48 is connected to four wires 49. A plug 47 is set above the connector 48, and the wires 49 pass through the plug 47. The top of the back cover 41 has a through hole 42 that matches the plug 47. Two lamp bodies 46 are installed at the bottom of the lamp holder 43. Two mounting screws 45 are symmetrically threaded at the bottom of the back cover 41. The bottom of the two mounting screws 45 is hinged to the top of the lamp holder 43 using a ball joint.

[0055] The lamp body 46 is mounted on the lamp holder 43, and the lamp holder 43 is connected to the back cover 41 by mounting screws 45 and dimming screws 44. That is, the mounting screws 45 hinge the two sides of the lamp holder 43 to the back cover 41, and the middle part of the lamp holder 43 is mounted by the dimming screws 44. When the dimming screws 44 are rotated, the angle of the lamp holder 43 can be adjusted, and the illumination angle of the lamp body 46 changes synchronously, thereby achieving the purpose of dimming.

[0056] The lamp body 46 is connected to the connector 48 via a wire. The connector 48 is connected to and transmits power via a wire 49. The wire 49 extends to the outside through the through hole 42. In order to position the wire 49 and seal the through hole 42, a plug 47 is used to assist in positioning the wire 49. Then the plug 47 is inserted into the through hole 42 to achieve the purpose of sealing.

[0057] See Figures 1-5 The frame mechanism 1 is equipped with a pressing component 2. When the product structure 4 is placed on top of the contour base 12, the pressing component 2 is used to press down the back cover 41 and tighten the dimming screw 44, thereby adjusting the angle of the lamp holder 43. The specific structure of the pressing component 2 is as follows:

[0058] The pressing assembly 2 includes a gantry frame 21 mounted on the top of the base frame 11 and a lifting cylinder 24. A lifting frame 22 is slidably connected to one side of the gantry frame 21. The top of the piston rod of the lifting cylinder 24 is connected to the lifting frame 22. A pressing adjustment mechanism 23 is installed at the bottom of the lifting frame 22. The lifting cylinder 24 is used to drive the lifting frame 22 to slide on the side wall of the gantry frame 21, thereby adjusting the height of the pressing adjustment mechanism 23. The pressing adjustment mechanism 23 is used to press down the product structure 4 and to obtain and tighten the dimming screw 44. The specific structure of the pressing adjustment mechanism 23 is as follows:

[0059] See Figures 1-5 The pressing and adjusting mechanism 23 includes two first columns 231 symmetrically connected to the bottom of the lifting frame 22, and two second columns 232 symmetrically connected to the top of the base frame 11. The two first columns 231 and the two second columns 232 are respectively arranged. A pressure head 236 is installed on one side of the bottom of the lifting frame 22. The pressure head 236 is adapted to the top of the rear cover 41. A bracket 233 is installed at the bottom of the lifting frame 22. Two positioning rods 234 are installed at the bottom of the bracket 233. The two positioning rods 234 are respectively arranged to correspond to two mounting screws 45. A servo motor 237 is installed at the top of the bracket 233. The output end of the servo motor 237 passes through the bottom of the bracket 233 and is connected to a rotating head 235. The bottom of the rotating head 235 is provided with a screwing groove that corresponds to the top of the dimming screw 44.

[0060] The lifting cylinder 24 is used to drive the lifting frame 22 and the pressing adjustment mechanism 23 to move down, causing the first column 231 and the second column 232 to dock. The rotating head 235 is sleeved on the top of the dimming screw 44, the pressing head 236 presses on the top of the back cover 41, and the two positioning rods 234 press on the top of the two mounting screws 45. Then the servo motor 237 drives the rotating head 235 to rotate, causing the dimming screw 44 to be rotated. At this time, since the two sides of the lamp holder 43 are hinged by the mounting screws 45, the dimming screw 44 will drive the middle part of the lamp holder 43 to move, and the angle of the lamp holder 43 will change. By presetting the rotation angle of the rotating head 235, the feed length of the dimming screw 44 can be controlled, thereby precisely adjusting the angle of the lamp holder 43.

[0061] See Figure 16 The bottom of the frame mechanism 1 is equipped with a test component 6. The test component 6 is used to test the swing angle of the lamp holder 43, and then determine whether the angle of the lamp holder 43 is within the preset swing angle range after the dimming screw 44 is precisely turned, and further determine whether the product structure 4 is a good product.

[0062] In the second embodiment, during the assembly of the wire 49 and the plug 47 and the subsequent closing of the headlight cover, the plug 47 is inserted and fixed by manually pulling the wire 49, and the wire 49 is pulled taut one by one. However, when the headlight bracket 43 and the rear cover 41 are merged, the plug 47 will exert a reverse squeezing force on the wire 49 inside the rear cover 41, causing the originally taut wire 49 to bend and deform. If the wire 49 is forcibly pulled to maintain its taut state, it will further aggravate the friction between the wire 49 and the inner wall of the plug 47, which may cause wear on the insulation layer of the wire 49 and affect the stability and safety of the electrical connection.

[0063] See Figures 7-11 For this purpose, a wire assembly 5 is provided. The wire assembly 5 is used to assist the operator in threading the wire 49. The specific structure of the wire assembly 5 is as follows:

[0064] See Figures 7-11 The wire assembly 5 includes a connecting tube 51 that passes through the plug 47, a swing plate 53 hinged inside the connecting tube 51, and a support block 58 connected to the bottom of the swing plate 53. The outer wall of the connecting tube 51 has a through groove 57 that mates with the support block 58. The operator first passes the connecting tube 51 through the bottom of the plug 47 and through the through hole 42. Then, the operator pinches the two swing plates 53 and brings them close to each other. The support block 58 extends out from the inside of the through groove 57 and fits against the bottom of the plug 47. At this time, pulling the wire assembly 5 will move the plug 47 upward and help it be inserted into the through hole 42 to complete the sealing. This setting allows the plug 47 to be accurately inserted into the through hole 42, preventing the plug 47 from being misaligned when manually pulling the wire 49 to guide it.

[0065] In the conventional method, if the length of the wire 49 between the plug 47 and the connector 48 is too long after the lamp holder 43 and the back cover 41 are combined, the wire 49 will be bent between the lamp holder 43 and the back cover 41, which will affect the sealing of the plug 47 and the pulling and tightening of the wire 49. If the length is too short, the plug 47 cannot be pulled out when the staff pulls the wire 49.

[0066] Therefore, after the wire assembly 5 passes through the plug 47, the plug 47 moves closer to the connector 48, which shortens the length of the wire 49 between the plug 47 and the connector 48, and the length is less than the distance between the connector 48 and the back cover 41. When the lamp holder 43 and the back cover 41 are combined, the degree of bending of the wire 49 between them is reduced. Then, by pulling the wire assembly 5 upward, the plug 47 slides along the extension direction of the wire 49, which not only guides the direction of the plug 47, but also reduces the possibility of the outer sheath of the wire 49 being scratched and damaged.

[0067] Specifically, the connecting tube 51 provides a precise guiding foundation by passing through the plug 47 and the through hole 42. In conjunction with the hinged linkage block 58 of the swing plate 53, it extends and retracts along the through groove 57, so that after the block 58 extends, it forms a stable force support point with the bottom of the plug 47. When the wire assembly 5 is pulled, the plug 47 can be moved upward along the axis of the connecting tube 51, which replaces the uncertain guiding method of manually pulling the wire 49, avoids the misalignment of the plug 47, and ensures the accuracy of sealing the through hole 42.

[0068] By bringing the plug 47 closer to the connector 48 to shorten the length of the wire 49 to less than the distance between the connector 48 and the back cover 41, the redundant length of the wire 49 is shortened, reducing bending deformation. At the same time, the component guides the plug 47 to slide along the extension direction of the wire 49, reducing the relative friction coefficient between the two. This reduces the bending of the wire 49 when the lamp holder 43 and the back cover 41 are combined, avoids insulation wear, and ensures the stability and safety of the electrical connection.

[0069] In Example 3, since there is a connection point between the wire 49 and the connector 48, the wire 49 may be pulled when the plug 47 is pulled. If the wire 49 is excessively taut inside the headlight, the point of impact will be at the connection point between the wire 49 and the connector 48, causing the connection point between the wire 49 and the connector 48 to crack and become poorly contacted.

[0070] For this purpose, please refer to Figures 7-11The wire assembly 5 also includes a first tube 54 disposed inside the connecting tube 51. The first tube 54 is rotatably connected to a second tube 55 via a bearing. The bottom end of the first tube 54 is connected to a second cross spring plate 501, and the outer wall of the bottom end of the first tube 54 is connected to a first cross spring plate 59. When the entire wire assembly 5 passes through the bottom of the plug 47, the first cross spring plate 59 and the second cross spring plate 501 are both below the plug 47. After the top of the connecting tube 51 passes through the plug 47, the four wires 49 are guided and separated by the cooperation of the first cross spring plate 59 and the second cross spring plate 501. Then the plug 47 moves closer to the connector 48, which shortens the length of the wires 49 between the plug 47 and the connector 48, and the length is less than the distance between the connector 48 and the back cover 41.

[0071] Subsequently, by rotating the first cross spring plate 59, the first cross spring plate 59 and the second cross spring plate 501 are misaligned and separated. The first cross spring plate 59 and the second cross spring plate 501 cooperate to assist in clamping the four wires 49. Then, the bolts are tightened to fix the axial angle of the first tube body 54 and the second tube body 55. Then, by pressing the two swing plates 53 to swing towards the center position of the connecting tube 51, the two support blocks 58 swing out from the inside of the through groove 57 and fit against the bottom position of the plug 47. The swing plate 53 and the connecting tube 51 are connected by a damping hinge to ensure the angle of the swing plate 53 after swinging.

[0072] See Figures 12-15 Below the pressing component 2, a driving component 3 is provided. The driving component 3 is installed at the bottom of the bracket 233. When the wire 49 is clamped by the first cross spring plate 59 and the second cross spring plate 501, the driving component 3 is used to connect with the wire assembly 5, thereby facilitating the driving of the wire assembly 5 for subsequent operations. The specific structure of the driving component 3 is as follows:

[0073] See Figures 12-15 The drive assembly 3 includes a fixed plate 31 disposed below the bracket 233 and a support plate 33 disposed below the fixed plate 31. Two first cylinders 32 are symmetrically mounted on the top of the support plate 33. The piston rods of the two support plates 33 are connected to the fixed plate 31. Two guide rods 34 are connected to the bottom of the fixed plate 31. The bottom of the guide rods 34 extends to the bottom of the support plate 33 and is connected to a mounting bracket 35. A sleeve 36 is inserted through the middle of the mounting bracket 35. A rod 39 is connected to the middle of the bottom surface of the fixed plate 31. The bottom end of the rod 39 passes through the support plate 33 and extends into the inside of the sleeve 36. The sleeve 36 and the mounting bracket 35 are locked together by bolts. The first cylinders 32 are used to drive the support plate 33 to move up and down, thereby driving the guide rods 34, the mounting bracket 35 and the sleeve 36 to move up and down.

[0074] See Figures 12-15The diameter of the connecting pipe 51 is smaller than the inner diameter of the sleeve 36. Two protrusions 38 are symmetrically connected to the inner wall of the sleeve 36. Two positioning grooves 52 are symmetrically opened on the top of the outer wall of the connecting pipe 51. The two positioning grooves 52 are corresponding to the two protrusions 38. Two blocks 56 are symmetrically connected to the top of the second pipe body 55. A slot 303 is opened at the bottom of the rod body 39. Two grooves 301 and two placement grooves 302 are symmetrically opened on the inner wall of the slot 303. The two grooves 301 and two placement grooves 302 are alternately arranged. The bottom of the groove 301 is through. A cavity is provided inside the slot 303 and above the grooves 301 and placement grooves 302. A second cylinder 37 is installed on the top of the bracket 233. The piston rod of the second cylinder 37 passes through the top of the bracket 233 and is connected to the top of the fixing plate 31.

[0075] The second cylinder 37 pushes the wire assembly 5 downwards as a whole. The operator inserts the top end of the connecting pipe 51 into the sleeve 36. At the same time, the protrusion 38 slides into the positioning groove 52. The top ends of the two blocks 56 and the second pipe 55 slide into the slot 303 through the two grooves 301. Then, by synchronously rotating the connecting pipe 51, the second pipe 55, and the first pipe 54, the protrusion 38 can slide and be limited inside the positioning groove 52. The two blocks 56 are displaced within the cavity of the slot 303 to their placement position. Once the slot 302 is engaged, the two first cylinders 32 are activated, causing the support plate 33 and mounting bracket 35 to move upwards. At this time, the mounting bracket 35 and sleeve 36 are locked together with bolts. Therefore, when the mounting bracket 35 moves upwards, it causes the sleeve 36 and connecting pipe 51 to move upwards as a whole. The connecting pipe 51 then pulls the swing plate 53 and support block 58 upwards. The support block 58 provides lifting force to the bottom of the plug 47, causing the plug 47 to slide upwards along the outer wall of the wire 49 until the plug 47 is inserted into the through hole. Inside 42, during this process, because the first cross spring plate 59 and the second cross spring plate 501 maintain the clamping state of the wire 49, and the first tube 54 and the second tube 55 do not move with the connecting tube 51 moving upward, the wire 49 will continue to be clamped. When the wire 49 is pulled upward, the first cross spring plate 59 and the second cross spring plate 501 provide a reverse downward force to the wire 49, reducing the intensity of the pull. After the movement is completed, the worker rotates the second tube 55 by rotating the rod 39. This causes the first cross spring plate 59 and the second cross spring plate 501 to return to their overlapping state. Then, the connecting pipe 51 is controlled to move downward, thereby squeezing the first cross spring plate 59 and the second cross spring plate 501, causing them to bend and retract into the connecting pipe 51. At this time, the squeezing block on the outer wall of the first pipe body 54 squeezes the two swing plates 53, causing the tilted swing plates 53 to swing to a vertical state. The support block 58 retracts into the through groove 57, and the second cylinder 37 drives the wire assembly 5 to move upward as a whole. The wire assembly 5 moves out from the inside of the plug 47.

[0076] Subsequently, the lifting cylinder 24 drives the lifting frame 22 and the pressing adjustment mechanism 23 to move down, the first column 231 and the second column 232 dock, the rotating head 235 is sleeved on the top of the dimming screw 44, the pressing head 236 presses on the top of the back cover 41, and the two positioning rods 234 press on the top of the two mounting screws 45. Then, the servo motor 237 drives the rotating head 235 to rotate, causing the dimming screw 44 to rotate. At this time, since the two sides of the lamp holder 43 are hinged by the mounting screws 45, the dimming screw 44 will drive the middle part of the lamp holder 43 to move, and the angle of the lamp holder 43 will change. By presetting the rotation angle of the rotating head 235, the feed length of the dimming screw 44 can be controlled, thereby precisely adjusting the angle of the lamp holder 43.

[0077] See Figure 16 The test component 6 includes two support frames 61 installed at the bottom of the base frame 11. Infrared rangefinders 62 are installed on the side walls of the two support frames 61. The two infrared rangefinders 62 are matched with the front and rear positions of the lamp holder 43. Test ports are opened at the bottom of the base frame 11 and the contour base 12. After the product structure 4 is placed on the top of the contour base 12 and the dimming screw 44 is turned, the height of the front and rear of the lamp holder 43 is tested by the infrared rangefinder 62. Then, it is determined whether the angle of the lamp holder 43 is within the preset swing angle range after the dimming screw 44 is precisely turned, and further, it is determined whether the product structure 4 is a good product.

[0078] Specifically, by setting the first cross spring plate 59, the second cross spring plate 501, the swing plate 53, the support block 58 and the drive component 3 of the wire assembly 5, in conjunction with the pressing and adjusting mechanism 23 and the testing component 6, the cross spring plate clamps the wire 49 to provide a reverse force, the drive component 3 drives the plug 47 to move, the servo motor 237 precisely adjusts the dimming screw 44, and the infrared rangefinder 62 detects the angle, thereby reducing the pulling strength of the wire 49, achieving precise adjustment of the lamp holder 43 angle and rapid judgment of product quality.

[0079] Example 4: An automated assembly and re-inspection process for a vehicle headlight dimming module, using the aforementioned automated assembly and re-inspection equipment for a vehicle headlight dimming module, includes the following steps:

[0080] S1. Pass the wire assembly 5 through the inside of the plug 47 and use the wire assembly 5 to assist in positioning the four wires 49, while the plug 47 is positioned close to the connector 48.

[0081] The more specific steps in S1 are as follows:

[0082] S11. Pass the entire wire assembly 5 through the bottom of the plug 47. At this time, the first cross spring plate 59 and the second cross spring plate 501 are both below the plug 47, and the top of the connecting tube 51 passes through the plug 47. The four wires 49 are guided and separated by the cooperation of the first cross spring plate 59 and the second cross spring plate 501.

[0083] S12. Then, the plug 47 moves closer to the connector 48, which shortens the length of the wire 49 between the plug 47 and the connector 48, and the length is less than the distance between the connector 48 and the back cover 41.

[0084] S13. Then, by rotating the first cross spring plate 59, the first cross spring plate 59 and the second cross spring plate 501 are misaligned and separated. The first cross spring plate 59 and the second cross spring plate 501 cooperate to assist in clamping the four wires 49. Then, the bolts are tightened to fix the axial angle of the first tube body 54 and the second tube body 55.

[0085] S14. Then, by pressing the two swing plates 53 to swing towards the center of the connecting pipe 51, the two support blocks 58 swing out from the inside of the through groove 57 and fit against the bottom of the plug 47. The swing plates 53 and the connecting pipe 51 are connected by a damping hinge to ensure the angle of the swing plates 53 after swinging.

[0086] S2. Then connect the wire assembly 5 to the drive assembly 3, and use the drive assembly 3 to control the wire assembly 5, causing the plug 47 to be pulled upward, causing the plug 47 to move upward along the outer wall of the four wires 49 and be inserted into the through hole 42. Then the wire assembly 5 removes the restriction on the wires 49 and the plug 47 and moves out.

[0087] The more specific steps of S2 are as follows:

[0088] S21. Then, the second cylinder 37 pushes the wire assembly 5 down as a whole. The worker inserts the top of the connecting pipe 51 into the sleeve 36. At the same time, the protrusion 38 slides into the positioning groove 52. The tops of the two blocks 56 and the second pipe 55 slide into the slot 303 through the two grooves 301. Then, by synchronously rotating the connecting pipe 51, the second pipe 55 and the first pipe 54, the protrusion 38 can slide and be limited inside the positioning groove 52. The two blocks 56 are displaced in the cavity of the slot 303 to the position of the placement groove 302 to complete the snap-fit.

[0089] S22. After the snap-fit ​​is completed, the two first cylinders 32 are activated. The two first cylinders 32 drive the bearing plate 33 and the mounting bracket 35 to move upward. At this time, the mounting bracket 35 and the sleeve 36 are locked together by bolts. Therefore, when the mounting bracket 35 moves upward, it drives the sleeve 36 and the connecting pipe 51 to move upward as a whole. The connecting pipe 51 pulls the swing plate 53 and the support block 58 to move upward. The support block 58 provides lifting force to the bottom of the plug 47. The plug 47 slides upward along the outer wall of the wire 49 until the plug 47 is inserted into the through hole 42.

[0090] S23. During this process, since the first cross spring plate 59 and the second cross spring plate 501 maintain the clamping state of the wire 49, and the first tube 54 and the second tube 55 do not move with the connecting tube 51, the wire 49 will continue to be clamped. When the wire 49 is pulled upward, the first cross spring plate 59 and the second cross spring plate 501 provide the wire 49 with a downward force in the opposite direction, reducing the intensity of the pull.

[0091] S24. After the movement is completed, the operator rotates the second tube 55 by rotating the rod 39, causing the first cross spring plate 59 and the second cross spring plate 501 to return to the overlapping state. Then, the connecting tube 51 is controlled to move down, thereby squeezing the first cross spring plate 59 and the second cross spring plate 501, causing them to bend and retract into the inside of the connecting tube 51. At this time, the squeezing block on the outer wall of the first tube 54 squeezes the two swing plates 53, causing the tilted swing plates 53 to swing to the vertical state. The support block 58 is retracted into the inside of the through groove 57. The second cylinder 37 drives the wire assembly 5 to move up as a whole, and the wire assembly 5 is moved out from the inside of the plug 47.

[0092] S3. Subsequently, the pressing component 2 presses against the back cover 41 and simultaneously screws the dimming screw 44, causing the angle of the lamp holder 43 to change. The screwing angle of the dimming screw 44 is precisely controlled. After the dimming screw 44 is screwed, the testing component 6 detects the angle of the lamp holder 43 to determine whether the product structure 4 meets the standard. After the determination is completed, the staff removes the product structure 4 and removes the wire assembly 5 from below the drive component 3.

[0093] The more specific steps for S3 are as follows:

[0094] S31. Subsequently, the lifting cylinder 24 drives the lifting frame 22 and the pressing adjustment mechanism 23 to move down, the first column 231 and the second column 232 dock together, the rotating head 235 is sleeved on the top of the dimming screw 44, the pressing head 236 presses on the top of the back cover 41, and the two positioning rods 234 press on the top of the two mounting screws 45.

[0095] S32. Then, the servo motor 237 drives the rotating head 235 to rotate, causing the dimming screw 44 to rotate. At this time, since the two sides of the lamp holder 43 are hinged by the mounting screw 45, the dimming screw 44 will drive the middle of the lamp holder 43 to move, and the angle of the lamp holder 43 will change.

[0096] S33. By setting the rotation angle of the rotating head 235, the feed length of the dimming screw 44 is controlled, thereby precisely adjusting the angle of the lamp holder 43. After the adjustment is completed, the height change of the lamp holder 43 is measured by two infrared rangefinders 62 to determine whether it meets the standard.

[0097] The more specific steps in S33 are:

[0098] S331. If the measured height is within the adjustment range, it is judged as a good product.

[0099] S332. If the measured height is not within the adjustment range, drive the dimming screw 44 to rotate in the opposite direction to the limit state, then rotate it forward again to the preset angle and number of turns, and then judge again. If the measured height is within the adjustment range, then judge it as a good product through step S331.

[0100] S333. If the height is still not within the adjustment range after re-inspection, it is determined that the back cover 41 and the lamp holder 43 have deformation or quality problems, and it is necessary to replace the parts and measure again.

[0101] S334. After the judgment is completed, the staff will remove the product structure 4 and remove the wire assembly 5 from below the drive assembly 3.

[0102] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
