Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically to a PCB board processing alignment device. Background Technology

[0002] In the PCB manufacturing process, in order to ensure that subsequent processing components (such as drilling, cutting, etc.) can be accurately aligned with specific positions on the PCB, an alignment device is needed to clamp and fix the PCB.

[0003] In the prior art, a PCB circuit board processing alignment and anti-deviation device with the publication number "CN220292270U" uses the setting of connecting blocks and mounting plates to make the rack move to the right. Through the meshing of the rack and gear, another set of racks moves to the left, driving the two sets of mounting blocks to move towards the center of the worktable. This causes the two sets of adjusting plates to move closer to each other, limiting the PCB circuit board and preventing alignment deviation during processing.

[0004] However, the above technical solutions and existing technologies have the following drawbacks: While this alignment and anti-deviation device can limit the movement of the PCB circuit board, in actual use it can only clamp and fix the left and right sides of the PCB circuit board, and cannot further limit the front and rear sides. This leads to the PCB circuit board shifting back and forth during subsequent processing, indicating that the limiting range needs improvement. Furthermore, the clamping structure in this anti-deviation device lacks a corresponding limiting structure to restrict the range of inward movement, making it very easy for the adjusting plate to clamp the PCB circuit board with excessive force during actual use. Once this happens, the PCB circuit board is prone to cracking and damage, thereby reducing the yield rate of the PCB circuit board and making its practicality poor. Utility Model Content

[0005] The purpose of this invention is to provide a PCB board processing alignment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A PCB board processing alignment device includes an alignment platform, on the upper surface of which a PCB board is placed. A fixing component is provided on the rear side of the upper surface of the alignment platform for clamping and fixing the PCB board. An auxiliary positioning component is provided on the front side of the upper surface of the alignment platform for blocking and positioning the front end of the PCB board.

[0007] Preferably, the fixing assembly includes a positioning clamp, a support platform, a bidirectional threaded rod, a guide cavity, and a first servo motor. The support platform is fixedly connected to the rear side of the upper surface of the positioning platform. The first servo motor is installed on the left end face of the support platform. The transmission end of the first servo motor is connected to the bidirectional threaded rod. Positioning clamps are threaded on both the left and right sides of the annular side of the bidirectional threaded rod. A guide cavity is opened on the front end face of the support platform, and the guide cavity matches the positioning clamp.

[0008] Preferably, a limit stop is installed on the right side of the upper surface of the support platform, and the limit stop matches the support platform. An extension piece is provided on the side of the limit stop, and a first internal thread through hole is opened on the front end face of the limit stop. A first fixing screw is installed inside the first internal thread through hole.

[0009] Preferably, the auxiliary positioning component includes a blocking block, an external threaded rod, a second servo motor, a limiting groove, and a moving block. The second servo motor is installed on the front end face of the alignment platform, and the transmission end of the second servo motor is connected to the external threaded rod. The moving block is threaded on the annular side of the external threaded rod, and the blocking block is connected to the upper end face of the moving block. A limiting groove is formed on the front side of the upper end face of the alignment platform, and the limiting groove matches the moving block.

[0010] Preferably, a follower rod is provided at the middle position of the front end face of the blocking block, and a limit stop ring is fitted on the front side of the annular side of the follower rod. A second internal threaded through hole is provided on the left side of the annular side of the limit stop ring, and a second fixing screw is installed inside the second internal threaded through hole.

[0011] Preferably, a second soft adhesive sheet is attached to the rear end face of the blocking block, and a support piece is fixedly connected to the front side of the upper end face of the alignment platform.

[0012] Preferably, a first soft rubber sheet is pasted on the inner wall of the positioning clamp, the positioning clamp is L-shaped, and an installation block is fixedly connected to the side of the alignment platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By controlling the second servo motor to rotate forward, the second servo motor can drive the blocking block to move backward through the external threaded rod and the moving block to block and limit the front end of the PCB board, while the support table will block and limit the rear end of the PCB board, thereby further positioning the front and rear ends of the PCB board. 2. By fixing the limiting bracket to the required position on the upper end of the support platform through the first fixing screw and the first internal thread through hole, the limiting bracket can block and limit the inward movement of the positioning clamp, so that the positioning clamp is in the same position each time it moves inward, avoiding the situation where the positioning clamp is clamped and fixed with excessive force, which may cause the PCB board to be damaged. 3. By fixing the limiting ring to the required position on the annular side of the follower rod with the second fixing screw and the second internal thread through hole, the support plate can restrict the backward moving blocking block through the limiting ring and the follower rod, so as to avoid the blocking block from exerting too much force on the PCB board and causing the PCB board to be damaged, thereby ensuring the yield of the PCB board.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: Example 1: A PCB board processing alignment device includes an alignment platform 1, with a mounting block 11 fixedly connected to the side of the alignment platform 1. The mounting block 11 facilitates the worker to install and fix the alignment platform 1 on the processing table. A PCB board 3 is placed on the upper surface of the alignment platform 1. A fixing component 4 is provided on the rear side of the upper surface of the alignment platform 1, and the fixing component 4 is used to clamp and fix the PCB board 3. An auxiliary positioning component 2 is provided on the front side of the upper surface of the alignment platform 1, and the auxiliary positioning component 2 is used to block and position the front surface of the PCB board 3 to prevent the PCB board 3 from shifting during subsequent processing.

[0018] The fixing component 4 includes a positioning clamp 41, a support platform 42, a bidirectional threaded rod 44, a guide cavity 45, and a first servo motor 46. The support platform 42 is fixedly connected to the rear side of the upper end face of the alignment platform 1. The support platform 42 is connected to the alignment platform 1 by welding. The support platform 42 can support the first servo motor 46 and the bidirectional threaded rod 44. The first servo motor 46 is installed on the left end face of the support platform 42. The first servo motor 46 is connected to an external servo controller through wires. When working, the first servo motor 46 can drive the bidirectional threaded rod 44 to rotate forward or reverse.

[0019] The first servo motor 46 is connected to a bidirectional threaded rod 44 at its transmission end. The external threads on the left and right sides of the annular side of the bidirectional threaded rod 44 rotate in opposite directions, so that the rotating bidirectional threaded rod 44 can drive the positioning clamps 41 on both sides to move synchronously in opposite directions. Positioning clamps 41 are threaded on both sides of the annular side of the bidirectional threaded rod 44. The positioning clamps 41 are L-shaped and can clamp and fix the PCB board 3. A guide cavity 45 is opened on the front end face of the support platform 42, and the guide cavity 45 matches the positioning clamps 41. The guide cavity 45 not only facilitates the lateral movement of the positioning clamps 41 inside the support platform 42, but also limits the positioning clamps 41 to prevent them from shaking or shifting during use.

[0020] A limit stop 43 is installed on the right side of the upper surface of the support platform 42. The limit stop 43 matches the support platform 42 and is concave in shape. The limit stop 43, which matches the support platform 42 and is concave in shape, can block and limit the positioning clamp 41 on the right side, preventing the positioning clamp 41 from clamping the PCB board 3 with excessive clamping force. An extension piece 431 is provided on the side of the limit stop 43. The extension piece 431 and the limit stop 43 are an integral structure. The extension piece 431 prevents the limit stop 43 from being used during operation. To prevent left-right swaying or shaking, the limit stop 43 is designed to ensure its stability. The front end of the limit stop 43 has a first internal threaded through hole 432, and a first fixing screw 433 is installed inside the first internal threaded through hole 432. The first internal threaded through hole 432 and the first fixing screw 433 can fix the limit stop 43 to the upper end of the support platform 42 for use. A first soft rubber sheet 411 is pasted on the inner wall of the positioning clamp 41. The first soft rubber sheet 411 prevents hard contact between the positioning clamp 41 and the PCB board 3, which could cause damage.

[0021] Example 2: Based on Embodiment 1, in this embodiment, by controlling the second servo motor 23 to rotate forward, the second servo motor 23 can drive the blocking block 21 to move backward through the external threaded rod 22 and the moving block 28 to block and limit the front end of the PCB board 3. The support platform 42 will block and limit the rear end of the PCB board 3, thereby further positioning the front and rear ends of the PCB board 3. The limiting ring 24, follower rod 26 and support plate 25 can prevent the blocking block 21 from exerting too much force when blocking and limiting the PCB board 3, which could cause the PCB board 3 to be damaged.

[0022] The auxiliary positioning component 2 includes a blocking block 21, an external threaded rod 22, a second servo motor 23, a limiting groove 27, and a moving block 28. The second servo motor 23 is installed on the front end face of the alignment platform 1. The second servo motor 23 is connected to an external servo controller via wires. When working, the second servo motor 23 can drive the external threaded rod 22 to rotate forward or backward. The transmission end of the second servo motor 23 is connected to the external threaded rod 22. The moving block 28 is installed on the annular side thread of the external threaded rod 22. The upper end face of the moving block 28 is connected to the blocking block 21. The blocking block 21 and the moving block 28 are an integral structure. When the external threaded rod 22 rotates, it can drive the blocking block 21 to move back and forth through the moving block 28. A limiting groove 27 is opened on the front side of the upper end face of the alignment platform 1, and the limiting groove 27 matches the moving block 28. The limiting groove 27 can limit the moving block 28 and prevent the moving block 28 from deviating or swinging during movement.

[0023] A follower rod 26 is provided at the middle position of the front end face of the blocking block 21, and the follower rod 26 is inserted inside the support plate 25. The follower rod 26 is connected to the blocking block 21 by welding. The follower rod 26 can move synchronously with the blocking block 21. A limit ring 24 is fitted on the front side of the annular side of the follower rod 26. The limit ring 24 can block and limit the follower rod 26 to prevent it from moving too far backward, so that the blocking block 21 is in the same position every time it moves backward. A second internal threaded through hole 241 is opened on the left side of the annular side of the limit ring 24. The second fixing screw 29 is installed in the threaded part. The second internal thread through hole 241 and the second fixing screw 29 can fix the limiting ring 24 at the required position on the annular side of the follower rod 26. The rear end face of the blocking block 21 is attached with a second soft rubber sheet 211. The second soft rubber sheet 211 prevents the blocking block 21 from making hard contact with the PCB board 3 and causing damage. The front side of the upper end face of the alignment plate 1 is fixedly connected with a support plate 25. The support plate 25 is connected to the alignment plate 1 by welding. The support plate 25 can not only support and limit the follower rod 26, but also block the limiting ring 24.

[0024] Working principle: During the processing of PCB board 3, the operator first controls the first servo motor 46 to drive the bidirectional threaded rod 44 to reverse, causing the bidirectional threaded rod 44 to drive the left and right sets of positioning clamps 41 to move inward synchronously. The first soft plastic sheet 411 will move synchronously with the positioning clamps 41. During this process, the operator uses a measuring ruler to measure and adjust the distance between the two sets of first soft plastic sheets 411 until the distance between the two sets of first soft plastic sheets 411 is the same as the width of the left and right sides of PCB board 3. At this time, the limit stop 43 can be placed on the support table. 42 is placed on the right side of the upper end face, and the right end face of the limiting bracket 43 is made to fit against the left end face of the positioning clamp 41 on the right side. Then, the first fixing screw 433 is rotated and fixed in the first internal thread through hole 432 with the help of a wrench. In this way, the limiting bracket 43 is fixed on the upper end of the support platform 42 for use, so that the limiting bracket 43 can block and limit the positioning clamp 41 on the right side, so that the positioning clamp 41 is in the same position each time it moves inward, and avoids the positioning clamp 41 from being too strong when clamping and fixing the PCB board 3, which may cause damage to the PCB board 3. Then, the second servo motor 23 is controlled to drive the external thread rod 22 to reverse, so that the reversed external thread rod 22 drives the blocking block 21 to move backward through the moving block 28. During this process, the staff uses a measuring ruler to measure and adjust the distance between the second soft film 211 and the support platform 42 until the distance between the second soft film 211 and the support platform 42 is adjusted to be the same as the front and rear width of the PCB board 3. At this time, the limiting ring 24 is fitted from front to back onto the annular side of the follower rod 26, and the rear end face of the limiting ring 24 is made to fit with the front end face of the support piece 25. Then, the second fixing screw 29 is rotated and fixed in the second internal thread through hole 241 with the help of an external wrench, so that the limiting ring 24 is fixed to the annular side of the follower rod 26 to limit it, so that the blocking block 21 is in the same position every time it moves backward, avoiding the blocking block 21 from being in the same position during the backward movement of the blocking block 21 to block and limit the PCB board 3, which may cause damage to the PCB board 3. This ensures the yield of the PCB board 3. After the limit stop 43 and the limit stop ring 24 are both installed in place, the first servo motor 46 and the second servo motor 23 are controlled to reverse, causing the positioning clamp 41 and the blocking block 21 to move outward a certain distance (see reference). Figure 2 At this point, the PCB board 3 to be processed can be placed flat on the alignment table 1. During this process, the rear end face of the PCB board 3 needs to be in contact with the front end face of the support table 42. After placement, the first servo motor 46 is controlled to drive the positioning clamps 41 on both sides to move inward synchronously through the bidirectional threaded rod 44 to clamp and fix the PCB board 3. During this process, the limit stop 43 will block and limit the positioning clamps 41 that have moved inward a certain distance to prevent the positioning clamps 41 from clamping and fixing the PCB board 3. Sometimes, excessive force can cause damage. After the PCB board 3 is clamped in place by the positioning clamping plate 41, the second servo motor 23 is controlled to drive the blocking block 21 to move backward through the external threaded rod 22 and the moving block 28 to block and limit the front end of the PCB board 3. During this process, the follower rod 26 and the limiting ring 24, which move together with the blocking block 21, will block and limit the blocking block 21 after it moves a certain distance backward, so as to prevent the blocking block 21 from moving too far when blocking and limiting the PCB board 3 and being damaged by clamping (see reference). Figure 1 This ensures the yield rate of PCB board 3. Then, the staff can carry out subsequent processing on PCB board 3. After the PCB board 3 is processed, the staff only needs to control the first servo motor 46 and the second servo motor 23 to reverse, so that the positioning clamp 41 and the blocking block 21 can move forward and unlock. At this time, the staff can take away the processed PCB board 3.
