Description
Technical Field
[0001] This utility model relates to the field of automatic core board alignment technology, specifically an automatic alignment device for large-size core boards. Background Technology
[0002] Core boards are important electronic components, serving as the support for electronic components and the carrier for their electrical interconnection. During core board processing, alignment devices are required to align the core boards so that they can be gripped by robotic arms later.
[0003] Existing core board alignment devices most commonly use mechanical fingers to push the core board along its four sides for center alignment. However, due to errors in the repeatability of the mechanical fingers during this pushing process, the center alignment accuracy of the core board is insufficient. Current center alignment methods use the four sides of the core board as a reference, thus requiring high flatness and parallelism of the four sides. Since large-sized core boards themselves have low edge precision and are prone to curling and deformation, the center alignment effect is unsatisfactory. Therefore, technological innovation and design optimization are needed to optimize an automatic alignment device for large-sized core boards. Utility Model Content
[0004] Existing core board alignment devices most commonly use mechanical fingers to push the core board along its four sides for center alignment. However, due to errors in the repeatability of the mechanical fingers during the pushing process, the center alignment accuracy of the core board is insufficient. Current center alignment methods use the four sides of the core board as a reference, thus requiring high flatness and parallelism of the four sides. Since large-sized core boards are inherently less precise on their four sides and prone to warping and deformation, the center alignment effect is unsatisfactory. To address these issues, this application provides an automatic alignment device for large-sized core boards. A movable industrial camera, along with limiting holes, determines the position of the core board. A sliding mechanism adjusts a moving plate, allowing the core board to move with the moving plate for secondary precise alignment, improving the alignment accuracy. Simultaneously, a rotary clamping mechanism clamps the core board, enhancing its stability during movement with the moving plate.
[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0006] An automatic alignment device for large-size core boards includes:
[0007] A base plate, wherein a placement plate is provided on the top of the base plate;
[0008] A support plate is located between a placement plate and a base plate. The support plate has left and right movable plates on both sides of its top. A left and right centering screw module is located on the top of the support plate, capable of moving the left and right movable plates left and right. The support plate also has front and rear movable plates on its other two sides of its top. A front and rear centering screw module is located on the top of the support plate, capable of moving the front and rear movable plates back and forth. Both the front and rear centering screw modules and the Zuoyou centering screw module are driven by a motor to rotate the screw. The screw drives the sliding movement within the slide groove. The slider is fixedly connected to the left and right movable plates and the front and rear movable plates, thereby driving the left and right movable plates and the front and rear movable plates to slide. A sliding mechanism is provided between the support plate and the base plate, enabling the support plate to slide.
[0009] Four industrial cameras are located at the four edges of the top of the base plate. The top of the support plate is provided with a front and rear camera drive mechanism and a left and right camera drive mechanism that can drive the industrial cameras to move. The front and rear camera drive mechanism and the left and right camera drive mechanism drive the industrial cameras to move through hydraulic rods.
[0010] A rotary clamping mechanism is located on the front and rear moving plates and the left and right moving plates, and is used to clamp the core plate in conjunction with the placement plate.
[0011] In one possible implementation, the sliding mechanism includes fixed blocks at the four corners of the top of the base plate, a movable block on the top of the fixed blocks, a sliding groove on the top of the fixed blocks, a sliding block inside the sliding groove, the sliding block being fixedly connected to the movable block, a sliding groove on the top of the movable block, a sliding groove 2 inside the sliding groove 2, the top of the sliding block 2 being fixedly connected to the bottom of the support plate, and two electric push rods on the top of the base plate. Under the action of the electric push rods, the support plate can be moved, the support plate can drive the sliding block 2 to slide in the sliding groove 1, and the movable block can drive the sliding block 1 to slide in the sliding groove 1, thereby completing the left-right and vertical movement of the support plate. At the same time, the fixed blocks and the movable blocks also support the support plate.
[0012] In one possible implementation, the two electric actuators are arranged perpendicularly to each other, and two fixed plates are fixed to the bottom of the support plate. The output ends of the two electric actuators respectively abut against the two fixed plates, so that the electric actuators can push the support plate through the fixed plates.
[0013] In one possible implementation, the rotary pressing mechanism includes a drive motor that can be fixed to the top of the left and right moving plates and the front and rear moving plates. An electric push rod is fixed to the output end of the drive motor, and a connecting plate is fixed to the output end of the electric push rod. A pressure block is fixed to the bottom of the connecting plate. The motor can drive the electric push rod to rotate, and the electric push rod can drive the pressure block to press the core plate, thereby improving the stability of the core plate when it moves with the support plate.
[0014] In one possible implementation, a rubber pad is fixed to the bottom of the pressure block to prevent damage to the core board.
[0015] In one possible implementation, limiting holes are provided on both the left and right moving plates and the front and rear moving plates. The limiting holes are located on the moving trajectory of the industrial camera, which facilitates the precise alignment of the steel plate by means of the core plate and the positions of the four limiting holes that block the four limiting holes.
[0016] In one possible implementation, the placement plate has several slots, and the output end of the electric push rod 2 can slide inside the slots on the placement plate, so that the electric push rod 2 can drive the clamping block to move on the placement plate.
[0017] In summary, this utility model has at least one of the following beneficial technical effects:
[0018] 1. The position of the core board is determined by setting a movable industrial camera in conjunction with the limiting hole. Then, the moving plate is adjusted by the sliding mechanism so that the core board moves with the moving plate, and the core board is precisely aligned a second time, which improves the alignment accuracy of the core board.
[0019] 2. The core board can be clamped by the rotating clamping mechanism, which helps to improve the stability of the core board when it moves with the moving plate. Attached Figure Description

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] This embodiment describes the specific structure of an automatic alignment device for large-size core boards, as detailed in the following reference. Figures 1-5 As shown, an automatic alignment device for large-size core boards includes:
[0028] Base plate 3, with a placement plate 1 on top of base plate 3;
[0029] Support plate 4 is located between placement plate 1 and base plate 3. Left and right moving plates 10 are provided on both sides of the top of support plate 4. A left and right centering screw module 6 is provided on the top of support plate 4 to drive the left and right moving plates 10 to move left and right. Front and rear moving plates 9 are provided on the other two sides of the top of support plate 4. A front and rear centering screw module 13 is provided on the top of support plate 4 to drive the front and rear moving plates 9 to move front and rear. Both the front and rear centering screw module 13 and the centering screw module are driven by a motor to rotate the screw. The screw drives the sliding movement within the groove. The slider is fixedly connected to the left and right moving plates 10 and the front and rear moving plates 9, thereby driving the left and right moving plates 10 and the front and rear moving plates 9 to slide. A sliding mechanism is provided between support plate 4 and base plate 3 to drive support plate 4 to slide.
[0030] Four industrial cameras 12 are located at the four edges of the top of the base plate 3. The top of the support plate 4 is equipped with a front and rear camera drive mechanism 23 and a left and right camera drive mechanism 5 that can drive the industrial cameras 12 to move. The front and rear camera drive mechanism 23 and the left and right camera drive mechanism 5 drive the industrial cameras 12 to move through hydraulic rods.
[0031] A rotary clamping mechanism is located on the front and rear moving plate 9 and the left and right moving plate 10, and is used to clamp the core plate in conjunction with the placement plate 1.
[0032] Existing core board alignment devices most commonly use a mechanical finger to push the core board along its four sides for center alignment. However, due to errors in the repeatability of the mechanical finger's positioning accuracy during this pushing process, the center alignment accuracy of the core board is insufficient. Current center alignment methods use the four sides of the core board as a reference, thus requiring high overall flatness and parallelism of the four sides. Since large-sized core boards themselves have low edge precision and are prone to curling and deformation, the center alignment effect is unsatisfactory, necessitating a secondary alignment to improve accuracy.
[0033] The sliding mechanism includes fixed blocks 7 at the four corners of the top of the base plate 3. The top of the fixed blocks 7 is provided with a movable block 14. The top of the fixed blocks 7 is provided with a sliding groove 18. The sliding groove 18 is provided with a sliding block 19. The sliding block 19 is fixedly connected to the movable block 14. The top of the movable block 14 is provided with a sliding groove 2 17. The sliding block 2 16 slides inside the sliding groove 2 17. The top of the sliding block 2 16 is fixedly connected to the bottom of the support plate 4. The top of the base plate 3 is provided with two electric push rods 15. Under the action of the electric push rods 15, the support plate 4 can be moved. The support plate 4 can drive the sliding block 2 16 to slide in the sliding groove 18. The movable block 14 can drive the sliding block 19 to slide in the sliding groove 18, thereby completing the left and right and vertical movement of the support plate 4. At the same time, the fixed blocks 7 and the movable blocks 14 also support the support plate 4.
[0034] In addition, the two electric push rods 15 are set perpendicular to each other, and two fixed plates are fixed at the bottom of the support plate 4. The output ends of the two electric push rods 15 abut against the two fixed plates respectively, so that the electric push rods can push the support plate 4 through the fixed plates.
[0035] Furthermore, the rotary pressing mechanism includes a drive motor 20 that can be fixed to the top of the left and right moving plate 10 and the front and rear moving plate 9. An electric push rod 21 is fixed to the output end of the drive motor 20, and a connecting plate 22 is fixed to the output end of the electric push rod 21. A pressure block 2 is fixed to the bottom of the connecting plate 22. The motor can drive the electric push rod 21 to rotate, and the electric push rod 21 can drive the pressure block 2 to press the core plate, thereby improving the stability of the core plate when it moves with the support plate 4.
[0036] It is worth noting that a rubber pad is fixed to the bottom of the pressure block 2 to prevent damage to the core board.
[0037] In one possible implementation, limiting holes 11 are provided on both the left and right moving plate 10 and the front and back moving plate 9. The limiting holes 11 are located on the moving trajectory of the industrial camera 12, which facilitates the precise alignment of the steel plate by means of the core plate and the positions of the four limiting holes 11 that block the four limiting holes.
[0038] More importantly, the placement plate 1 has several slots 8, and the output end of the electric push rod 21 can slide inside the slots 8 on the placement plate 1, so that the electric push rod 21 can drive the clamping block to move on the placement plate 1.
[0039] When the staff needs to align the core board, the robotic arm places the large core board to be aligned onto the placement plate 1. The left and right centering screw modules 6 and the front and rear centering screw modules 13 are activated, sending the rotary clamping mechanism to the edge of the core board. Then, the rotary clamping mechanism is activated to clamp the edge of the core board. Next, the front and rear camera drive mechanism 23 and the left and right camera drive mechanism 5 are activated to move the industrial camera 12. The industrial camera 12 moves to the bottom of the limiting hole 11 and is activated. The industrial camera 12 takes pictures and adjusts the placement plate 1 according to the size of the core board blocking the limiting hole 11, thereby achieving precise alignment of the core board.
[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
