Description

Technical Field

[0001] This invention relates to the field of rectifier bridge technology, specifically to a rectifier bridge assembly device for automotive alternators. Background Technology

[0002] A rectifier bridge is an electronic device that converts alternating current (AC) into direct current (DC), and it is widely used in power supplies, motor control, and electronic equipment. It achieves rectification of AC power through the unidirectional conductivity of its internal diodes. A rectifier bridge typically consists of a semi-finished bridge, a plastic housing, and an insulating plate. After the individual parts of the rectifier bridge are completed, the components need to be assembled; usually, the plastic housing is press-fitted onto the semi-finished bridge.

[0003] Existing rectifier bridge assembly equipment typically assembles semi-finished rectifier bridges and plastic housings by first placing the plastic housing on the semi-finished rectifier bridge, and then pressing it onto the bridge using a stamping mechanism. This assembly method requires stopping the transport of the semi-finished rectifier bridge during the placement of the plastic housing, prolonging the assembly time and reducing efficiency. Furthermore, it cannot guarantee the proper alignment between the plastic housing and the semi-finished rectifier bridge, potentially leading to a mismatch and damage to both during subsequent stamping, thus increasing assembly costs.

[0004] Therefore, there is a need to provide a rectifier bridge assembly device for automotive alternators, which aims to solve the above problems. Summary of the Invention

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0046] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0047] In one embodiment of the present invention, see Figures 1-2 An assembly device for a rectifier bridge for an automotive alternator includes a bracket 1. The bracket 1 is provided with a transport component 2 for transporting a semi-finished rectifier bridge 8. The transport component 2 is provided with a positioning component 3 that is movably engaged with the bracket 1. The positioning component 3 is used to position the semi-finished rectifier bridge 8. The bracket 1 is equipped with a transmission component 4 located above the transport component 2. The transmission component 4 is movably equipped with a swing component 5 that is movably fitted with a plastic housing 9. The swing component 5 is provided with an adjustment component 7. The end of the bracket 1 near the loading end of the semi-finished rectifier bridge 8 is equipped with a placement component 6 located above the positioning component 3. The placement component 6 is movably engaged with the swing component 5.

[0048] In this embodiment, the stable transportation and centered positioning of the semi-finished rectifier bridge 8 can be achieved through the cooperation of the transport component 2 and the positioning component 3. This can meet the transportation and positioning needs of semi-finished rectifier bridges 8 of different specifications, improving the applicability of the device. Through the cooperation of the transport component 2, the transmission component 4, the swing component 5 and the placement component 6, the single transfer of the plastic shell 9 and the precise assembly of the semi-finished rectifier bridge 8 and the plastic shell 9 can be achieved, avoiding the low efficiency of step-by-step transfer and assembly. Through the placement component 6, the plastic shell 9 can be automatically pushed to the right, facilitating the extraction of the plastic shell 9 on the right side. It has the effects of stable transportation, flexible centered positioning, efficient and precise assembly, flexible linkage, automatic pushing, reliable structure and convenient operation.

[0049] The bracket 1 includes symmetrically arranged side plates and a horizontal plate connecting the two side plates. Support plates are installed at both ends of the bottom of the side plates to provide stable support for the device.

[0050] In one embodiment of the present invention, see Figures 1-3 The transport component 2 includes a first rotating roller (not shown in the figure) and a second rotating roller (not shown in the figure) respectively rotatably disposed at both ends of the support 1. The first rotating roller and the second rotating roller are connected by a transport belt 205. A support plate (not shown in the figure) located in the inner ring of the transport belt 205 is installed inside the support 1. The support plate is used to support the transport belt 205 above. A rotary motor 201 connected to the end of the first rotating roller is installed on the side wall of the support 1. The other end of the first rotating roller is connected to a first pulley 202. One end of the second rotating roller is connected to a second pulley 204. The first pulley 202 and the second pulley 204 are connected by a first synchronous belt 203.

[0051] In this embodiment, the rotary motor 201 drives the first rotary roller to rotate clockwise. The first rotary roller is connected to the first pulley 202, the first synchronous belt 203 and the second pulley 204 to drive the second rotary roller to rotate synchronously. This can drive the conveyor belt 205 to rotate clockwise. The conveyor belt 205 drives the semi-finished rectifier bridge 8 to move synchronously by driving the positioning component 3 located on it to move synchronously. This can realize the feeding of the semi-finished rectifier bridge 8 and the transportation of the assembled finished product, improve the assembly efficiency of the device and avoid the low efficiency of manual handling.

[0052] The first pulley 202 has the same size as the second pulley 204, which ensures that the rotation speed of the conveyor belt 205 is stable.

[0053] In one embodiment of the present invention, see Figures 1-3 The positioning component 3 includes guide ring grooves 301 symmetrically arranged on one side of the bracket 1. Several pairs of retaining rings 302 are evenly distributed on the conveyor belt 205. A first placement frame 304 located on the outer side of the conveyor belt 205 is movably arranged between each pair of retaining rings 302. Both ends of the first placement frame 304 are provided with rotating posts 303 that rotate with the retaining rings 302. The outer end of the rotating post 303 is movably engaged with the guide ring groove 301. A first electric cylinder 305 is symmetrically installed on the inner side wall of the first placement frame 304. The ends of the first electric cylinders 305 that are close to each other are connected to clamps 306 that slide with the first placement frame 304.

[0054] In this embodiment, initially, the symmetrically arranged clamping plates 306 are far apart from each other. When the semi-finished rectifier bridge 8 is placed on the first placement frame 304 and located between the symmetrically arranged clamping plates 306, the first electric cylinder 305 extends towards the center of the first placement frame 304 and pushes the clamping plates 306 to move synchronously. The symmetrically arranged clamping plates 306 clamp the semi-finished rectifier bridge 8 by moving closer to each other. Through the rotational engagement of the rotating column 303 and the retaining ring 302, and the movable engagement of the rotating column 303 and the guide ring groove 301, the stability of the position of the first placement frame 304 can be ensured, avoiding the first placement frame 304 from shifting after one rotation, thus improving the assembly accuracy.

[0055] The clamping plates 306 are provided with V-shaped grooves on their adjacent sides for clamping the semi-finished rectifier bridge 8. The V-shaped grooves can clamp the four corners of the semi-finished rectifier bridge 8, thereby achieving the centering positioning of the semi-finished rectifier bridge 8. This can meet the centering positioning requirements of semi-finished rectifier bridges 8 of different specifications, facilitate the precise assembly between the semi-finished rectifier bridge 8 and the plastic shell 9, help reduce assembly errors and scrap rate, and improve the yield.

[0056] In one embodiment of the present invention, see Figures 1-7 The transmission assembly 4 includes mounting plates 401 symmetrically arranged on both sides of the bracket 1. The upper parts of the two mounting plates 401 are connected by a guide plate 410. A rotating rod 405 is rotatably provided between the two mounting plates 401. The rotating rod 405 is provided with an inclined ring groove 406. A sliding seat 407 that slides with the inclined ring groove 406 is movably provided on the rotating rod 405. The sliding seat 407 slides with the guide plate 410. A first hinge post 407 is provided on the sliding seat 407. 1. A movable slide frame 408 is slidably provided on two mounting plates 401. The end of the movable slide frame 408 is provided with a second hinge post 4081. A hinge plate 409 is rotatably connected between the second hinge post 4081 and the first hinge post 4071. One end of the rotating rod 405 is connected to a fourth pulley 404. The end of the second rotating roller away from the second pulley 204 is connected to a third pulley 402. A second synchronous belt 403 is connected between the third pulley 402 and the fourth pulley 404.

[0057] The swing assembly 5 includes a first guide groove 501 disposed on the mounting plate 401 and a second guide groove 502 disposed on the movable slide frame 408. A pin 504 is installed on one side wall of the mounting plates 401 that are close to each other. A movable slot plate 505 is symmetrically and movably disposed between the two mounting plates 401. The movable slot plate 505 is provided with a strip groove 5051 that movably engages with the pin 504. The two movable slot plates 505 are connected by a connecting plate 506 at one end away from the pin 504. A sliding column 503 is provided on the side wall of the movable slot plate 505 away from the connecting plate 506, which slidably engages with the first guide groove 501 and the second guide groove 502 respectively. A vacuum pump 507 is symmetrically and movably disposed on the connecting plate 506. An air suction hood 508 is connected to the bottom of the vacuum pump 507.

[0058] The first guide groove 501 includes a first vertical groove 5011 and a horizontal groove 5013. The ends of the first vertical groove 5011 and the horizontal groove 5013 that are close to each other are connected by a first inclined groove 5012. The second guide groove 502 includes a second inclined groove 5021 and a second vertical groove 5022. The height of the second inclined groove 5021 is the same as the height of the first vertical groove 5011. The vertical height of the first guide groove 501 is the same as the vertical height of the second guide groove 502.

[0059] The adjustment assembly 7 includes a third guide groove 701 disposed on the movable slot plate 505, a sliding frame 702 movably disposed between the two movable slot plates 505 and slidingly engaged with the third guide groove 701, a fourth guide groove 704 symmetrically disposed on the sliding frame 702 and slidingly engaged with the air pump 507, a second electric cylinder 703 connected between the connecting plate 506 and the sliding frame 702, a driven gear 707 rotatably disposed on the sliding frame 702 and located between the two air pumps 507, an adjustment groove 708 symmetrically distributed on the driven gear 707 and slidingly engaged with the air pump 507, a driving gear 706 rotatably disposed on the sliding frame 702 and meshing with the driven gear 707, and the driving gear 706 connected to an adjustment motor 705 disposed at the bottom of the sliding frame 702.

[0060] In this embodiment, in the initial state, the sliding seat 407 is located at the end of the rotating rod 405 away from the second hinge post 4081, the included angle between the hinge plate 409 and the rotating rod 405 is at its minimum value, the sliding post 503 is in sliding engagement with the lowest point of the first vertical groove 5011 and the lowest point of the second inclined groove 5021 respectively, and the pin 504 is in sliding engagement with the end of the strip groove 5051 away from the connecting plate 506. At this time, the semi-finished rectifier bridge 8 and the plastic shell 9 are in the assembly completion stage.

[0061] The rotary motor 201 drives the first pulley 202 to rotate synchronously by driving the first rotary roller. The first pulley 202 drives the second pulley 204 to rotate synchronously by connecting to the first synchronous belt 203. The second pulley 204 drives the third pulley 402 to rotate synchronously by connecting to the second rotary roller. The third pulley 402 drives the fourth pulley 404 to rotate by connecting to the second synchronous belt 403. The fourth pulley 404 drives the rotating rod 405 to rotate synchronously. The rotating rod 405 drives the sliding seat 407 to reciprocate on the rotating rod 405 by sliding engagement between the inclined ring groove 406 and the sliding seat 407 and the guide plate 410.

[0062] As the sliding seat 407 moves toward the end of the rotating rod 405 that is close to the second hinge post 4081, the sliding seat 407 pushes the movable slide frame 408 away from the rotating rod 405 by rotating it with the hinge plate 409 and sliding it with the mounting plate 401. The angle between the hinge plate 409 and the rotating rod 405 increases, and the movable slide frame 408 drives the second guide slide groove 502 to move synchronously.

[0063] During the sliding engagement of the slide column 503 and the second inclined groove 5021, the adhesion between the suction hood 508 and the plastic shell 9 is first released to avoid the drawback of the subsequent upward movement of the suction hood 508 causing the plastic shell 9 to move upward. Since the slide column 503 can only move vertically in the first vertical groove 5011, when the second guide groove 502 moves towards the horizontal groove 5013, the second inclined groove 5021 drives the slide column 503 to move upward by sliding engagement with the slide column 503 and sliding engagement with the first vertical groove 5011. The slide column 503 drives the movable groove plate 505 and the connecting plate 506 to move upward synchronously by the movable engagement of the strip groove 5051 and the pin 504. The connecting plate 506 drives the suction hood 508 to move upward by the movable engagement of the suction pump 507 and the movable connection of the adjusting component 7 and the suction pump 507. The connection between the suction hood 508 and the plastic shell 9 is released, which facilitates the continued transportation of the assembled finished product and the subsequent transportation of the semi-finished product rectifier bridge 8.

[0064] When the sliding column 503 moves upward and begins to slide into the bottom of the second vertical groove 5022, the sliding column 503 begins to slide into the first inclined groove 5012. The moving slide frame 408 continues to move away from the rotating rod 405. The second vertical groove 5022 drives the movable groove plate 505 to rotate upward by sliding into the sliding column 503, sliding into the first inclined groove 5012, and sliding into the strip groove 5051 and the pin 504. The movable groove plate 505 drives the air pump 507 and the suction hood 508 to rotate synchronously by connecting to the connecting plate 506.

[0065] When the sliding column 503 moves to its highest point and begins to slide into the horizontal groove 5013, the sliding column 503 still slides into the second vertical groove 5022. At this time, the movable groove plate 505 rotates 90 degrees, and the movable sliding frame 408 continues to move away from the rotating rod 405. The second vertical groove 5022 drives the movable groove plate 505 to move closer to the placement component 6 by sliding into the sliding column 503, sliding into the first inclined groove 5012, and sliding into the strip groove 5051 and the pin 504. The sliding column 503 drives the air pump 507 and the suction hood 508 to move synchronously by driving the movable groove plate 505 and the connecting plate 506 to move synchronously. The cooperation of 507 and suction hood 508 can adsorb the plastic shell 9 located on the far right of the placement component 6, realizing the single gripping of the plastic shell 9. At this time, the included angle between the hinge plate 409 and the rotating rod 405 is at its maximum value. When the rotating rod 405 continues to rotate, the sliding seat 407 pushes the moving slide frame 408 closer to the rotating rod 405 by rotating it with the hinge plate 409 and sliding it with the mounting plate 401. The included angle between the hinge plate 409 and the rotating rod 405 becomes smaller. The moving slide frame 408 drives the second guide slide groove 502 to move synchronously. The sliding seat 407 begins to move towards the end of the rotating rod 405 away from the second hinge post 4081.

[0066] The sliding column 503 drives the movable slot plate 505 to move away from the placement component 6 by sliding engagement with the second vertical slot 5022 and the horizontal slot 5013. The movable slot plate 505 drives the plastic shell 9 to move horizontally synchronously by the suction hood 508 being in contact with the plastic shell 9. Next, the sliding column 503 drives the movable slot plate 505 to rotate downward by sliding engagement with the second vertical slot 5022 and the first inclined slot 5012, so that the movable slot plate 505 rotates from a horizontal state to a vertical state. During this process, the plastic shell 9 rotates synchronously. Then, the sliding column 503 drives the movable slot plate 505 to move downward by sliding engagement with the second inclined slot 5021 and the first vertical slot 5011. The movable slot plate 505 drives the plastic shell 9 to move vertically downward by connecting to the connecting plate 506 and by the suction hood 508 being in contact with the plastic shell 9.

[0067] When the semi-finished rectifier bridge 8 moves directly below the plastic housing 9, the plastic housing 9 is assembled with the semi-finished rectifier bridge 8 by moving vertically downwards. This allows for a one-time operation of gripping and assembling the plastic housing 9, avoiding the separate steps of placing the plastic housing 9 on the semi-finished rectifier bridge 8 and assembling the semi-finished rectifier bridge 8 and the plastic housing 9, thus improving assembly efficiency.

[0068] Meanwhile, by controlling the extension and retraction of the second electric cylinder 703, the distance between the sliding frame 702 and the connecting plate 506 can be adjusted, thereby adjusting the height of the suction hood 508 to meet the assembly operations of plastic shells 9 of different heights. When the size of the plastic shell 9 is large, the adjusting motor 705 drives the drive gear 706 to rotate. The drive gear 706 meshes with the driven gear 707, the driven gear 707 rotates with the sliding frame 702, and the adjusting groove 708 slides with the suction pump 507 to drive the two suction pumps 507 to move away from each other. The suction pumps 507 drive the corresponding suction hoods 508 to move synchronously to meet the adsorption operation of the larger plastic shell 9. The adjusting component 7 improves the applicability of the device by cooperating with the positioning component 3.

[0069] In one embodiment of the present invention, see Figures 1-9 The placement component 6 includes a second placement frame 602 disposed above the positioning component 3 for temporarily storing the plastic shell 9. The second placement frame 602 has an opening at one end near the transmission component 4. The two side walls of the second placement frame 602 are connected to the bracket 1 through a fixing frame 603. A second push plate 604 is slidably disposed inside the second placement frame 602 to abut against the plastic shell 9. A first spring 605 is connected between the left end of the second placement frame 602 and the second push plate 604. An abutment plate 606 is rotatably disposed at the bottom of the end of the second placement frame 602 near the opening to abut against the plastic shell 9. A movable plate 607 is connected to the end of the abutment plate 606 away from the plastic shell 9. A second spring 608 is connected between the movable plate 607 and the bottom of the second placement frame 602. A first push plate 601 is disposed at one end of the suction hood 508 to movably abut against the second spring 608.

[0070] In this embodiment, in the initial state, several plastic shells 9 are sequentially attached to one end of the second placement frame 602 near the transmission component 4. The first spring 605 is in a contracted state. The second push plate 604 abuts against one plastic shell 9 at the end away from the transmission component 4. The abutting plate 606 abuts against one plastic shell 9 at the end near the transmission component 4. The second spring 608 is in a contracted state, which can position the several plastic shells 9.

[0071] After the suction hood 508 rotates to a horizontal position, the connecting plate 506 moves closer to the second placement frame 602, causing the suction pump 507 and the suction hood 508 to move synchronously, so that the suction hood 508 is in contact with the outer wall of the plastic shell 9. Through the suction pump 507, the suction hood 508 is stably adsorbed on the surface of the plastic shell 9. During this process, before the suction hood 508 contacts the outer wall of the plastic shell 9, the outer end of the first push plate 601 contacts the movable plate 607 first. As the suction hood 508 continues to move closer to the plastic shell 9... At the same time, the suction hood 508 drives the first push plate 601 to move synchronously, and the movable plate 607 is connected to the abutment plate 606 and the abutment plate 606 is rotated in conjunction with the second placement frame 602 to drive the abutment plate 606 to rotate downward. The second spring 608 is stressed and contracts, which can release the abutment of the plastic shell 9 on the side close to the transmission component 4, so that the plastic shell 9 on the side close to the transmission component 4 is in a movable state. When the suction hood 508 is in contact with the outer wall of the corresponding plastic shell 9, the adsorption of the plastic shell 9 is realized.

[0072] When the connecting plate 506 moves away from the second placement frame 602 and drives the air pump 507 and the suction hood 508 to move synchronously, it can drive the plastic shell 9 being adsorbed to move synchronously, thereby realizing the gripping of the plastic shell 9. The suction hood 508 drives the first push plate 601 to move synchronously, releasing the first push plate 601 from the contact with the movable plate 607. The second spring 608 extends and pushes the movable plate 607 and the contact plate 606 to rotate upward, which can realize the re-clamping of the plastic shell 9 on the second placement frame 602, which facilitates the subsequent adsorption operation of the plastic shell 9.

[0073] The length of the abutment plate 606 is less than the length of the movable plate 607, and the first push plate 601 is set as an L-shaped plate to avoid interference with the adsorption of the plastic shell 9.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
