Description

Technical Field

[0001] This utility model relates to the field of board separation fixture technology, specifically a board separation fixture for limiting and anti-collision components of circuit boards. Background Technology

[0002] In the field of circuit board processing and manufacturing, the depaneling process is an important step in separating multi-panel circuit boards into single qualified products. To ensure that the circuit boards are not damaged during the depaneling process and that the depaneling accuracy meets the standards, it is usually necessary to use a depaneling fixture to position and fix the circuit boards. Therefore, the structural rationality of the depaneling fixture directly affects the processing quality and production efficiency of the circuit boards.

[0003] Existing board separation fixtures lack structural designs capable of achieving precise initial positioning when limiting the circuit board, making it difficult to guarantee the accuracy of the initial placement position of the circuit board. In the pressing stage, the fit between the pressing components and the fixture body is not stable enough, and there is a lack of reliable fixing points to constrain the offset of the pressing components, which makes the circuit board prone to loosening during the pressing process. At the same time, there is a lack of effective suction and straightening devices between the fixture's cover and the base plate, which cannot further enhance the stability of their fit. This makes the circuit board prone to offset or even collision during the separation process, which may not only damage the integrity of the circuit board, but also reduce the reliability and accuracy of the separation operation, making it difficult to meet the requirements of high-precision circuit board processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a board separation fixture for circuit board limiting and anti-collision components, thereby solving the problems mentioned in the background art, such as reduced reliability and accuracy of board separation operations, and difficulty in meeting the requirements of high-precision circuit board processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a board separation fixture for limiting and preventing collisions on circuit boards, comprising: The base plate has a first limiting hole at the corner of its upper surface and a second limiting hole on both sides of its upper surface. A pressure cap is disposed on the upper surface of the base plate. A circuit board is provided on the lower surface of the pressure cap. A page chain fixing device is installed on the upper surface of the base plate. Fixing points of the fixing device are evenly distributed on the upper surface of the page chain fixing device. The page chain is set on both sides of the upper surface of the page chain fixing device. The upper surface of the page chain has a first fixing point and a second fixing point below the first fixing point. The upper surface of the pressure cover is equipped with a magnetic suction device.

[0006] Preferably, the upper surface of the base plate is equipped with limiting points and a handle position. The limiting points can accurately position the components placed on the base plate to ensure the accuracy of the component's position during the installation process. The handle position allows the operator to quickly and comfortably pick up or place the entire panel jig, improving work efficiency.

[0007] Preferably, the handle is a notch formed at the edge of the base plate, and the inner wall of the notch has an arc-shaped transition surface, so that the operator can directly contact the edge of the circuit board through the notch, which is convenient for picking up and putting down the circuit board.

[0008] Preferably, a limiting device is installed on the upper surface of the base plate, and the surface of the limiting device is provided with limiting fixing points, which can be tightly matched with the circuit board to improve the limiting effect.

[0009] Preferably, the surface of the circuit board is provided with a hemispherical protrusion, and the surface of the limiting device is provided with an arc-shaped positioning groove. The hemispherical protrusion is installed inside the arc-shaped positioning groove, which can fix the circuit board.

[0010] Preferably, the upper surface of the circuit board is equipped with suction plates at positions corresponding to the magnetic suction device. The magnetic suction device and the suction plates are fully attached. When the cover presses the circuit board, the magnetic suction device and the suction plates are fully attached and attracted, preventing the circuit board from lifting in some areas.

[0011] Compared with the prior art, this utility model provides a board separation fixture for limiting and anti-collision components of circuit boards, which has the following beneficial effects: This board separation fixture for circuit board positioning and anti-collision components uses a first and second limiting hole on the base plate to initially position the circuit board, ensuring accurate initial positioning. Then, a pressure cap fastens the circuit board and uses a hinge chain for pressing. The hinge chain, through its first and second fixing points, cooperates with the fixing points of the hinge chain fixing device to ensure stable pressing and prevent displacement. Simultaneously, the pressure cap utilizes a magnetic attraction device to achieve attraction and fixation through the pressure cap fixing points, further enhancing the stability of the fit between the pressure cap and the base plate. Through the synergistic effect of these structures, the entire process effectively prevents the circuit board from loosening, shifting, or colliding during the separation process, protecting the integrity of the circuit board and improving the reliability and accuracy of the separation operation.

[0014] 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.

[0015] This utility model provides a technical solution: a board separation fixture for limiting and anti-collision components of circuit boards. Please refer to [link / reference]. Figure 1 It includes a base plate 1, a first limiting hole 2 is provided at the corner of the upper surface of the base plate 1, and a second limiting hole 3 is provided on both sides of the upper surface of the base plate 1. A pressure cap 4 is disposed on the upper surface of the base plate 1. A circuit board 5 is disposed on the lower surface of the pressure cap 4. A chain fixing device 6 is mounted on the upper surface of the base plate 1. Please refer to [link / reference]. Figure 3 The upper surface of the page chain fixing device 6 is evenly provided with fixing points 61; Page chain 7 is set on both sides of the upper surface of page chain fixing device 6. The upper surface of page chain 7 has a first fixing point 71 and a second fixing point 72 below the first fixing point 71. A magnetic suction device 8 is installed on the upper surface of pressure cover 4.

[0016] The circuit board 5 is placed on the base plate 1, and the cover 4 is pressed onto the circuit board 5 by the page chain 7 device. Then, the cover 4 has two fixing points that are attracted and fixed by the magnetic attraction device 8.

[0017] The circuit board 5 is initially positioned by the first limiting hole 2 and the second limiting hole 3 on the base plate 1 to ensure accurate initial positioning. Then, the cover 4 fastens the circuit board 5 and presses it together with the page chain 7. The page chain 7 cooperates with the fixing point 61 of the fixing device 6 of the page chain fixing device 6 through the first fixing point 71 and the second fixing point 72 on it to ensure that the pressing process is stable and not easy to shift. At the same time, the cover 4 uses the magnetic attraction device 8 on it to achieve attraction and fixation through the fixing point of the cover 4, further enhancing the stability of the fit between the cover 4 and the base plate 1. Through the synergistic effect of the various structures, the circuit board 5 is effectively prevented from loosening, shifting or colliding during the separation process, which not only protects the integrity of the circuit board 5, but also improves the reliability and accuracy of the separation operation.

[0018] Please see Figure 1 The upper surface of the base plate 1 is fitted with a limited location 9. Please refer to [link / reference]. Figure 2 The upper surface of the base plate 1 is equipped with a handle position 10 and a limiting point 9, which can accurately position the parts placed on the base plate 1 to ensure the accuracy of the parts' position during the installation process. The handle position 10 allows operators to quickly and comfortably pick up or place the entire panel jig, improving work efficiency.

[0019] The handle 10 is a notch opened at the edge of the base plate 1. The inner wall of the notch has an arc-shaped transition surface, allowing the operator to directly contact the edge of the circuit board 5 through the notch, making it convenient to pick up and put down the circuit board 5.

[0020] Please see Figure 1 A limit device 11 is installed on the upper surface of the base plate 1. Please refer to [link / reference]. Figure 4 The surface of the limiting device 11 is provided with limiting fixing points 12, which can be tightly fitted with the circuit board 5 to improve the limiting effect.

[0021] Please see Figure 5 The surface of circuit board 5 is fitted with hemispherical protrusions 14, please refer to [reference needed]. Figure 4 The surface of the limiting device 11 is provided with arc-shaped positioning grooves 15, and the hemispherical protrusions 14 are installed inside the arc-shaped positioning grooves 15 to fix the circuit board 5.

[0022] Please see Figure 5 The upper surface of the circuit board 5 is equipped with suction plates 13 at the corresponding positions of the magnetic suction device 8. The magnetic suction device 8 and the suction plates 13 are completely attached. When the cover 4 presses the circuit board 5, the magnetic suction device 8 and the suction plates 13 are completely attached and attracted, preventing the circuit board 5 from being partially lifted.

[0023] By placing the circuit board 5 into the base plate 1, and limiting it through the limiting device 11 of the circuit board 5 and the limiting fixing point 12 of the pressure cover 4, the fixture makes full use of the limiting fixing point 12 and the magnetic suction device 8 to limit and fix it, thus avoiding the technical problems of the circuit board 5 not being able to be fixed and floating deviation during the division.

[0024] In operation, the circuit board 5 is initially positioned precisely through the first limiting hole 2, the second limiting hole 3, and the limiting point 9 on the base plate 1. Simultaneously, the limiting device 11 on the base plate 1 tightly engages with the circuit board 5 through its limiting fixing point 12, and the hemispherical protrusion 14 on the surface of the circuit board 5 is further fixed within the arc-shaped positioning groove 15 on the surface of the limiting device 11. Next, the pressure cover 4 is fastened to the circuit board 5, and the page chain 7 is used for pressing. The page chain 7, through the first fixing point 71, the second fixing point 72, and the fixing point 61 of the page chain fixing device 6, ensures stable pressing. Finally, the pressure cover 4 uses its magnetic suction device 8 to completely adhere and attract the corresponding suction piece 13 on the upper surface of the circuit board 5. The two fixing points of the pressure cover 4 achieve suction and fixation. Throughout the process, the various structures work together to effectively prevent the circuit board 5 from loosening, shifting, or colliding during the separation process, solving the technical problems of the circuit board 5 not being able to be fixed and floating deviation during separation.
