Description

Technical Field

[0001] This invention relates to the field of automotive processing equipment technology, specifically to an auxiliary device for assembling automotive parts. Background Technology

[0002] In the process of automobile manufacturing, workers need to install internal parts of the vehicle body. Due to the narrow interior of the car, it is not convenient for large machinery to enter. Currently, the installation is mostly done manually by workers. In order to improve assembly efficiency, major manufacturers use some auxiliary assembly equipment during the assembly process to increase production capacity. According to a Chinese patent with authorization announcement number CN113199234B, an auxiliary device for automobile parts assembly is disclosed. It can assist workers in delivering parts and screws in the assembly line operation during automobile manufacturing. Workers do not need to walk around frequently to pick up parts and screws, saving time and effort. It can also accurately control the number of screws picked up, avoiding workers from missing or picking up the wrong screws, thus improving work efficiency.

[0003] This automotive parts assembly auxiliary device supplies bolts via belt conveyor. However, due to differences in assembly speed among different workers, it is difficult for the device to ensure that the conveyor speed is synchronized with the workers' assembly speed. If the assembly speed of the workers is lower than the conveyor belt's feeding speed, bolts will accumulate at the assembly station. Furthermore, the device is insufficient in supplying bolts of different types, failing to meet the requirement of freely switching between different bolt types during assembly. Therefore, we propose an automotive parts assembly auxiliary device to solve the above-mentioned technical problems. Summary of the Invention

[0043] As a preferred embodiment of the present invention, it further includes:

[0044] The louvers are located on the lower part of the outer surface of the profile cabinet, and multiple louvers are provided. The louvers are used for heat dissipation of the stepper locking motor.

[0045] As a preferred embodiment of the present invention, it further includes:

[0046] An acrylic guard plate is fixedly installed on the lower part of the side of the pre-storage hopper away from the cross bracket. The acrylic guard plate is used to protect the feeding section and the adjustment section.

[0047] Compared with the prior art, the beneficial effects of the present invention are:

[0048] 1. In this invention, the output shaft of the locking motor drives the active gear to rotate, and the driven gear further drives the central vertical shaft and the cross bracket to rotate together. The rotation of the cross bracket drives the four feeding parts to rotate together, and the feeding part containing the corresponding model and specification of bolts is rotated to face the assembly station. The setting of the switching part makes it convenient to select bolts of different specifications, which is highly practical.

[0049] 2. In this invention, by pulling the bolt located between the two clamping flaps downward, the bolt's nut applies a downward squeezing force to the two clamping flaps, causing the two clamping flaps to rotate downward along the outer wall of the clamping flaps at a certain angle, and then the bolt can be pulled out directly. This is convenient to operate and greatly improves assembly efficiency.

[0050] 3. In this invention, during the process of the clamping flip plate rotating downwards and then upwards to reset, the trigger block will rotate twice, causing the trigger rod of the trigger switch to extend outwards and then be squeezed back by the trigger block. When the trigger rod of the trigger switch retracts, it transmits the reset signal of the clamping flip plate to the controller. The controller immediately starts the servo motor, causing its output shaft to drive the active pulley to rotate. The rotation of the active pulley, through the transmission between the power belt and the driven pulley, further drives the feeding horizontal shaft and the grooved wheel to rotate at a certain angle, conveying the bolt in the groove of the grooved wheel to the top of the two clamping flip plates. Under the action of gravity, the bolt naturally falls from the groove of the grooved wheel to the top of the two clamping flip plates. Since the gap between the clamping flip plates is smaller than the diameter of the bolt nut, the bolt is stuck between the two clamping flip plates and remains in a vertical position, waiting for the worker to pick it up next time, thus achieving on-demand supply and preventing bolts from accumulating at the assembly station.

[0051] 4. In this invention, the rotation of the adjusting screw generates a threaded thrust effect between it and the adjusting seat, causing one adjusting seat, which is threadedly connected to the adjusting screw, to move along the axial direction of the guide rod. Simultaneously, the movement of this adjusting seat drives the reversing gear to rotate via the push bar and rack connected to it. The rotation of the reversing gear further drives another rack and push bar to move in the opposite direction, thereby driving the other adjusting seat to move. This adjusts the distance between the two adjusting seats, which in turn adjusts the spacing between the two clamping flaps. This makes it suitable for feeding bolts of different thicknesses, thus expanding the applicability of this device. Attached Figure Description

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Please see Figures 1 to 8The technical solution provided by the present invention specifically includes the following embodiments:

[0063] An auxiliary device for assembling automotive parts includes a profile cabinet 100; a switching section 200 disposed on the top of the profile cabinet 100 and extending into the interior of the profile cabinet 100; four feeding sections 300 disposed around the switching section 200; two adjusting sections 400 disposed on the bottom sides of the feeding sections 300; a controller 500 disposed on the left side of the profile cabinet 100; and a trigger switch 600 disposed inside the feeding sections 300.

[0064] For further details, please refer to [link / reference]. Figures 1-3 As shown:

[0065] The switching unit 200 includes a central vertical shaft 201, which is rotatably mounted at the top center of the profile cabinet 100; a cross bracket 202, which is fixedly mounted on the upper part of the outer wall of the central vertical shaft 201, and the feeding unit 300 is fixedly mounted on the end of the cross bracket 202 by fixing bolts; a driven gear 203, which is fixedly mounted on the lower part of the outer wall of the central vertical shaft 201; a stepper locking motor 204, which is fixedly mounted on the inner side of the upper surface of the profile cabinet 100, and the output shaft of the stepper locking motor 204 extends to the top periphery of the profile cabinet 100, and the stepper locking motor 204 is electrically connected to the controller 500; and a driving gear 205, which is fixedly mounted on the output of the stepper locking motor 204, and the driving gear 205 and the driven gear 203 mesh with each other, and the gear ratio of the driving gear 205 and the driven gear 203 is 1:9.

[0066] Specifically, by inputting instructions to the controller 500, the controller 500 controls the stepper locking motor 204 to start, causing its output shaft to drive the drive gear 205 to rotate. This, in turn, drives the central vertical shaft 201 and the cross bracket 202 to rotate together through the transmission action of the driven gear 203. The rotation of the cross bracket 202 causes the four feeding parts 300 to rotate together. After the feeding part 300 containing the corresponding bolts is rotated to an angle facing the assembly station, the stepper locking motor 204 stops running and locks its output shaft, preventing the adjusted feeding part 300 from rotating again and ensuring stability. The switching part 200 facilitates the selection of bolts of different specifications, making it highly practical.

[0067] Furthermore, refer to Figures 2-8 As shown:

[0068] The feeding unit 300 includes a pre-storage hopper 301, which is fixedly installed at the end of the cross bracket 202 for storing bolts; a feeding frame 302, which is fixedly installed at the bottom of the pre-storage hopper 301, and the interior of the feeding frame 302 is connected to the interior of the pre-storage hopper 301; a feeding horizontal shaft 303, which is rotatably installed inside the feeding frame 302 along the radial direction of the central vertical shaft 201; and a grooved wheel 304, which is located inside the feeding frame 302 and fixedly installed on the outer wall of the feeding horizontal shaft 303, with a gap of 1.5 to 2.0 mm between the outer wall of the grooved wheel 304 and the inner wall of the feeding frame 302.

[0069] The feeding unit 300 also includes a driven pulley 305, fixedly mounted on the rear of the outer wall of the feeding horizontal shaft 303, used to drive the feeding horizontal shaft 303 to rotate. A servo motor 306 is fixedly mounted on the outer surface of the pre-storage hopper 301, and the servo motor 306 is electrically connected to the controller 500; a driving pulley 307 is fixedly mounted on the output shaft of the servo motor 306; a power belt 308 is fixedly mounted around the driven pulley 305 and the driving pulley 307, used to transmit power from the driving pulley 307 to the driven pulley 305; and two adjusting seats 309 are located around the pre-storage hopper 301, symmetrically distributed about the axis of the feeding horizontal shaft 303, triggering a switch 60. 0 is fixedly installed inside one of the adjusting seats 309 along the radial direction of the feeding horizontal axis 303; the shaft pin 3010 is fixedly set on both sides of the adjusting seat 309; the clamping flap 3011 is rotatably set on the outer wall of the two adjusting seats 309 located on both sides of the shaft pin 3010; the torsion spring 3012 is fixedly set on the periphery of the shaft pin 3010, and the torsion spring 3012 is fixedly installed between the adjusting seat 309 and the shaft pin 3010, for the rotational reset of the clamping flap 3011; the torsion spring 3012 is fixedly set in the middle of the inner side of the clamping flap 3011 near the trigger switch 600, and the side of the trigger block 3013 away from the feeding horizontal axis 303 abuts against the end of the trigger rod of the trigger switch 600.

[0070] Specifically, as shown in the attached document Figure 4As shown, the worker pulls the bolt located between the two clamping flaps 3011 downwards. The bolt's nut applies a downward squeezing force to the two clamping flaps 3011, causing them to rotate downwards along the outer wall of the clamping flaps 3011 by a certain angle. This downward rotation of the clamping flaps 3011 causes the torsion spring 3012 to elastically deform, generating a rebound force. When the bolt's nut slides out from between the two clamping flaps 3011, the rebound force of the torsion spring 3012 causes the clamping flaps 3011 to rotate upwards along the outer wall of the shaft pin 3010 to reset. During the downward and upward rotation of the clamping flaps 3011, the trigger block 3013 rotates twice, causing the trigger rod of the trigger switch 600 to extend outwards and then be squeezed back by the trigger block 3013. When the trigger switch 600 touches... After the launcher retracts, it transmits the reset signal of the clamping flip plate 3011 to the controller 500. The controller 500 immediately starts the servo motor 306, causing its output shaft to drive the drive pulley 307 to rotate. The rotation of the drive pulley 307, through the transmission effect of the power belt 308 and the driven pulley 305, further drives the feeding horizontal shaft 303 and the grooved wheel 304 to rotate at a certain angle, conveying the bolts located in the groove of the grooved wheel 304 to the top of the two clamping flip plates 3011. Under the action of gravity, the bolts naturally fall from the groove of the grooved wheel 304 to the top of the two clamping flip plates 3011. Since the gap between the clamping flip plates 3011 is smaller than the diameter of the bolt nut, the bolts are stuck between the two clamping flip plates 3011 and remain in a vertical position, waiting for the worker to pick them up next time, thus achieving on-demand supply and preventing bolts from accumulating at the assembly station.

[0071] Furthermore, refer to Figures 4-8 As shown:

[0072] The adjusting unit 400 includes an adjusting screw 401, which is rotatably mounted on one side of the feeding frame 302 along the radial direction of the feeding horizontal axis 303. The adjusting screw 401 passes through one of the adjusting seats 309 and is threadedly connected to the through hole of the adjusting seat 309. Guide rods 402 are fixedly mounted on the outer surface of the feeding frame 302 along the radial direction of the feeding horizontal axis 303. There are four guide rods 402 on the outer surface of the same feeding frame 302. The four guide rods 402 are equally divided on both sides about the central axis of the feeding frame 302, and the two guide rods located on both sides of the feeding frame 302 are... An adjusting seat 309 is slidably connected to guide rods 402 distributed on both sides of the feeding frame 302; a pusher 403 is fixedly installed at one end of the adjusting seat 309, and the pusher 403 is bent at a right angle; a rack 404 is fixedly installed on the top of the pusher 403; a positioning shaft 405 is fixedly installed on the outer surface of the feeding frame 302 along the axial direction of the feeding horizontal shaft 303; a reversing gear 406 is rotatably installed on the outer wall of the feeding horizontal shaft 303, and the reversing gear 406 meshes with the upper and lower racks 404 to move the upper and lower racks 404 synchronously.

[0073] Specifically, by rotating the adjusting screw 401 and the adjusting seat 309 to generate a threaded thrust, one adjusting seat 309, which is threadedly connected to the adjusting screw 401, moves along the axial direction of the guide rod 402. At the same time, the movement of the adjusting seat 309 drives the reversing gear 406 to rotate through the push bar 403 and rack 404 connected to it. The rotation of the reversing gear 406 further drives the other rack 404 and push bar 403 to move in the opposite direction, thereby driving the other adjusting seat 309 to move. The distance between the two adjusting seats 309 is adjusted. Adjusting the distance between the two adjusting seats 309 is also adjusting the distance between the two clamping flaps 3011, thus making it suitable for feeding bolts of different thicknesses and improving the applicability of this device.

[0074] Furthermore, refer to Figures 1-2 As shown:

[0075] It also includes a cabinet door 101, which is rotatably mounted on the front of the profile cabinet 100, and the cabinet door 101 is installed with the profile cabinet 100 via hinges.

[0076] By setting cabinet door 101, it is easy to open the profile cabinet 100. On the one hand, it is convenient to maintain the stepper locking motor 204 in the future. On the other hand, it can close the interior of the profile cabinet 100 and improve the storage effect of the profile cabinet 100.

[0077] It also includes louvers 102, which are opened on the lower part of the outer surface of the profile cabinet 100, and multiple louvers 102 are provided.

[0078] By opening the louver 102, the stepper locking motor 204 can be cooled, thus preventing damage to the stepper locking motor 204 due to poor heat dissipation.

[0079] It also includes an acrylic guard plate 700, which is fixedly installed on the lower part of the side of the pre-storage hopper 301 away from the cross bracket 202. The acrylic guard plate 700 is used to protect the feeding part 300 and the adjustment part 400.

[0080] In this solution, an auxiliary device for assembling automotive parts allows for the independent placement of bolts of different models through four pre-storage bins 301. The device is easily moved to the assembly station by the casters at the bottom of the profile cabinet 100, and the controller 500 is oriented towards the assembly station for easy operation.

[0081] When bolts are needed, the worker inputs a command to the controller 500, which then controls the stepper locking motor 204 to start, causing its output shaft to drive the drive gear 205 to rotate. This, in turn, drives the central vertical shaft 201 and the cross bracket 202 to rotate together through the transmission action of the driven gear 203. The rotation of the cross bracket 202 causes the four feeding parts 300 to rotate together. After the feeding part 300 containing the corresponding bolts is rotated to an angle facing the assembly station, the stepper locking motor 204 stops running and locks its output shaft, preventing the adjusted feeding part 300 from rotating again and ensuring stability.

[0082] As attached Figure 4 As shown, the worker pulls the bolt located between the two clamping flaps 3011 downwards. The bolt's nut applies a downward squeezing force to the two clamping flaps 3011, causing them to rotate downwards along the outer wall of the clamping flaps 3011 by a certain angle. This downward rotation of the clamping flaps 3011 causes the torsion spring 3012 to elastically deform, generating a rebound force. When the bolt's nut slides out from between the two clamping flaps 3011, the rebound force of the torsion spring 3012 causes the clamping flaps 3011 to rotate upwards along the outer wall of the shaft pin 3010 to reset. During the downward and upward rotation of the clamping flaps 3011, the trigger block 3013 rotates twice, causing the trigger rod of the trigger switch 600 to extend outwards and then be squeezed back by the trigger block 3013. When the trigger switch 600 touches... After the launcher retracts, it transmits the reset signal of the clamping flip plate 3011 to the controller 500. The controller 500 immediately starts the servo motor 306, causing its output shaft to drive the drive pulley 307 to rotate. The rotation of the drive pulley 307, through the transmission between the power belt 308 and the driven pulley 305, further drives the feeding horizontal shaft 303 and the grooved wheel 304 to rotate at a certain angle, conveying the bolt in the groove of the grooved wheel 304 to the top of the two clamping flip plates 3011. Under the action of gravity, the bolt naturally falls from the groove of the grooved wheel 304 to the top of the two clamping flip plates 3011. Since the gap between the clamping flip plates 3011 is smaller than the diameter of the bolt nut, the bolt is stuck between the two clamping flip plates 3011 and remains in a vertical position, waiting for the worker to pick it up next time, thus achieving on-demand supply and preventing bolts from accumulating at the assembly station.

[0083] This device generates a threaded thrust effect between the adjusting screw 401 and the adjusting seat 309 by rotating the adjusting screw 401. This causes one adjusting seat 309, which is threadedly connected to the adjusting screw 401, to move axially along the guide rod 402. Simultaneously, the movement of this adjusting seat 309 drives the reversing gear 406 to rotate via the push bar 403 and rack 404 connected to it. The rotation of the reversing gear 406 further drives the other rack 404 and push bar 403 to move in the opposite direction, thereby driving the other adjusting seat 309 to move. This adjusts the distance between the two adjusting seats 309, which in turn adjusts the spacing between the two clamping flaps 3011. This allows the device to assist in feeding bolts of different thicknesses, thus expanding its applicability.

[0084] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
