Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a clamping device for etching processing of multilayer circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) are essential components in electronic devices, used to support and connect various electronic components.

[0003] Patent CN219938616U discloses a fixture for processing circuit boards. It includes a worktable with a movable groove. A movable block is located within the movable groove, and the movable block is movably positioned within the groove via a movable component. A lead screw groove is located within the movable block, and a bidirectional lead screw is rotatably mounted within the lead screw. A first clamping component and a second clamping component are movably mounted on the bidirectional lead screw. While this patent uses the first and second clamping components for fixation, it only allows clamping one circuit board at a time. For tasks requiring the processing of a large number of circuit boards, this increases production time. Furthermore, the bidirectional lead screw drives the clamping blocks to hold the circuit board, directly squeezing the circuit board with the two clamping blocks without a buffer structure, resulting in excessive clamping force and potential problems such as circuit board cracking.

[0004] Therefore, there is a need for a multilayer circuit board etching clamping device that can simultaneously hold multiple circuit boards. Utility Model Content

[0005] To overcome the shortcomings of existing patents, which can only clamp one circuit board at a time, increasing production time for tasks requiring the processing of a large number of circuit boards, and whose bidirectional screw-driven clamping blocks directly squeeze the circuit board without a buffer structure, resulting in excessive clamping force and causing circuit board cracking, this utility model provides a multi-layer circuit board etching processing clamping device that can clamp multiple circuit boards simultaneously.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a multilayer circuit board etching and clamping device, comprising a processing table, and further comprising a first guide rod, a first sliding plate, a slide rod, a clamping plate, a first elastic element, a second elastic element, a cylinder, a guide plate, and limiting blocks. Three sets of first guide rods are fixedly connected to the processing table. A first sliding plate is slidably mounted on the first guide rod. A second elastic element is sleeved on the first guide rod, with both ends of the second elastic element connected to the processing table and the first sliding plate, respectively. Two slide rods are slidably mounted on the first sliding plate, with a clamping plate fixedly connected between the two slide rods. A first elastic element is sleeved on the slide rod, with both ends of the first elastic element connected to the clamping plate and the first sliding plate, respectively. A cylinder is mounted on the processing table, and a guide plate is mounted on the telescopic rod of the cylinder. Six limiting blocks are fixedly connected to the processing table.

[0007] Furthermore, it also includes a mounting base, a second guide rod, a screw, a dual-axis motor, a second sliding plate, and a positioning plate. The mounting base is fixedly connected to the worktable, and the second guide rod is fixedly connected to the mounting base. The dual-axis motor is mounted on the worktable, and screws are mounted on both output shafts of the dual-axis motor via couplings. The screws rotate on the mounting base, and the second sliding plate is threaded onto the screw. The second sliding plate slides on the second guide rod, and three positioning plates are fixedly connected to the second sliding plate.

[0008] Preferably, it also includes a placement plate, which is fixedly connected to the worktable.

[0009] Furthermore, it also includes limit plates, with four limit plates fixedly connected to the placement plate.

[0010] Furthermore, four triangular reinforcing ribs are fixedly connected to the workbench.

[0011] Furthermore, the positioning plate is made of rubber.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By activating the cylinder, the extension rod of the cylinder extends and drives the guide plate to move backward to squeeze the second elastic element. The guide plate moves backward and simultaneously squeezes the six first sliding plates to move inward. The inward movement of the first sliding plates drives the clamping plate and the two sliding rods to move inward. After the clamping plate contacts the circuit board, the circuit board squeezes the clamping plate to move outward. The clamping plate drives the two sliding rods to move outward and simultaneously squeezes the first elastic element. In this way, three circuit boards can be clamped at the same time. Moreover, the clamping plate can automatically adjust its position according to the actual size of the circuit board and provide appropriate clamping force through the compression of the elastic element to avoid damage to the circuit board caused by uneven pressure.

[0013] 2. By starting the dual-axis motor, the two output shafts of the dual-axis motor drive the two screws to rotate. The screws drive the second sliding plate to move inward along the second guide rod. At the same time, the second guide rod drives the three positioning plates to move inward, so that the six positioning plates push the circuit board and thus accurately position the circuit board, thereby placing the circuit board at the center of the processing point and ensuring processing accuracy.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example 1: A clamping device for etching multilayer circuit boards, see reference. Figures 1-6As shown, the assembly includes a processing table 1, a first guide rod 2, a first sliding plate 3, a slide rod 4, a clamping plate 5, a first elastic element 6, a second elastic element 7, a cylinder 8, a guide plate 9, and a limiting block 10. Three sets of first guide rods 2 are evenly spaced and fixedly connected to the processing table 1, with two first guide rods 2 forming a group. A first sliding plate 3 is slidably mounted on each first guide rod 2. A second elastic element 7 is sleeved on each first guide rod 2, with both ends of the second elastic element 7 connected to the processing table 1 and the first sliding plate 3, respectively. The upper part of the first sliding plate 3... The sliding mechanism has two sliding rods 4, and a clamping plate 5 is bolted between the ends of the two sliding rods 4. A first elastic element 6 is sleeved on the sliding rod 4, and the two ends of the first elastic element 6 are connected to the clamping plate 5 and the first sliding plate 3 respectively. A cylinder 8 is installed at the front of the processing table 1. A guide plate 9 is installed on the telescopic rod of the cylinder 8. When the guide plate 9 moves backward, it can simultaneously squeeze the six first sliding plates 3 to move inward. Six limiting blocks 10 are fixedly connected to the worktable, and the guide plate 9 slides on the six limiting blocks 10.

[0023] See Figure 1 As shown, it also includes a placement plate 17, which is fixedly connected to the front of the worktable.

[0024] See Figure 1 As shown, it also includes limiting plates 18. Four limiting plates 18 are fixedly connected to the top of the placement plate 17 at even intervals. The four limiting plates 18 are located at the four corners of the placement plate 17 respectively.

[0025] See Figures 1-6 As shown, four triangular reinforcing ribs are fixedly connected to the workbench.

[0026] See Figure 1 and Figure 4 As shown, the positioning plate 16 is made of rubber.

[0027] When clamping the circuit boards, first place the three circuit boards on the three clamping points of the processing table 1, so that one circuit board is between two clamping plates 5. Then, activate the cylinder 8. The extension rod of the cylinder 8 extends, causing the guide plate 9 to move backward and compress the second elastic element 7. The second elastic element 7 is compressed accordingly. As the guide plate 9 moves backward, it also compresses the six first sliding plates 3, causing them to move inward. The inward movement of the first sliding plates 3 causes the clamping plate 5 and the two sliding rods 4 to move inward. After the clamping plate 5 contacts the circuit board, the circuit board compresses the clamping plate 5 and moves it outward. The clamping plate 5 then moves the two sliding rods 4 outward and compresses the first elastic element 6. The first elastic element 6 is then compressed. Compression allows for the simultaneous clamping of three circuit boards. The clamping plate 5 automatically adjusts its position according to the actual size of the circuit board and provides appropriate clamping force through the compression of the elastic element, preventing damage to the circuit board due to uneven pressure. After clamping, the circuit board can be processed. The placement plate 17 can support the circuit board to be processed, and the four corner limiting plates 18 limit the circuit board to be processed. After processing, the finished circuit board is removed, and the first elastic element 6 drives the two sliding rods 4 and the clamping plate 5 to reset. Then, the extension rod of the driving cylinder 8 retracts, driving the guide plate 9 to reset. The second elastic element 7 then drives the first sliding plate 3 and the components above it to reset.

[0028] Example 2: Based on Example 1, refer to Figure 1 , Figure 4 and Figure 5 As shown, it also includes a mounting base 11, a second guide rod 12, a screw 13, a dual-axis motor 14, a second sliding plate 15, and a positioning plate 16. The mounting base 11 is fixedly connected to the center of the worktable. The second guide rod 12 is bolted to the left side of the mounting base 11. The dual-axis motor 14 is mounted on the worktable. Screws 13 are mounted on both output shafts of the dual-axis motor 14 via couplings. The screws 13 rotate on the mounting base 11. The second sliding plate 15 is threaded onto the screw 13. The second sliding plate 15 slides on the second guide rod 12. Three positioning plates 16 are fixedly connected to the second sliding plate 15 at even intervals. The positioning plates 16 are located between the two clamping plates 5.

[0029] After clamping is completed, the dual-axis motor 14 is started. The two output shafts of the dual-axis motor 14 drive the two screws 13 to rotate. The screws 13 drive the second sliding plate 15 to move inward along the second guide rod 12. At the same time, the second sliding plate 15 drives the three positioning plates 16 to move inward, so that the six positioning plates 16 push the circuit board and accurately position the circuit board, so that the circuit board is located at the center of the processing point, ensuring processing accuracy. After positioning is completed, the output shaft of the dual-axis motor 14 drives the screws 13 to reverse, so that the second sliding plate 15 and the positioning plates 16 are reset.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
