Description

Technical Field

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

[0002] PCB stands for Printed Circuit Board, an important electronic component. It serves as the support for electronic components and provides electrical connections for them. The PCB depaneling process is a crucial step in PCB manufacturing, affecting the PCB's electrical performance, mechanical strength, appearance quality, and other fundamental characteristics. Therefore, a PCB depaneling device is needed.

[0003] A Chinese patent with authorization announcement number CN213152504U discloses a PCB separation device, belonging to the field of PCB processing technology. It includes a bracket, on which a separation plate and a stamping die are provided. The separation plate and the bracket are fixedly connected. The separation plate is provided with a release hole. The stamping die is located above the separation plate. The stamping die is provided with a separation column at the position corresponding to the release hole. The bracket is provided with a driving component for raising and lowering the stamping die. This application has the effect of reducing the labor intensity of workers and improving work efficiency.

[0004] However, the above solution still has some problems. When separating PCBs, debris will be generated and adsorbed on the PCB. If the PCB is collected directly by a drawer, it will be necessary to clean the separated PCB again, which will reduce the PCB processing efficiency. Therefore, a PCB separation device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a PCB depaneling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a PCB depaneling device, including: a base, a first support groove symmetrically opened inside the base, a fixing groove symmetrically opened inside the first support groove, a water tank movably connected inside the base, a second support groove opened inside the water tank, a separation plate placed on the second support groove, support rods fixedly connected to both sides of the water tank, the support rods slidably connected inside the first support groove, a positioning block fixedly connected to one side of the support rod, the positioning block slidably connected inside the first support groove, a fixing pad fixedly connected to the upper surface of the positioning block, the fixing pad movably connected inside the fixing groove, a first spring fixedly connected to the inner wall of the fixing pad, one end of the first spring fixedly connected to one side of the positioning block, pulling the water tank outwards from the base, causing the fixing pad to move from the rear fixing groove to below the front fixing groove, and under the push of the first spring, the fixing pad enters the front fixing groove, thus fixing the position of the water tank and preventing the water tank from falling out of the base.

[0007] Preferably, the base has a sliding groove inside, and a receiving plate is slidably connected inside the sliding groove. The base has symmetrically opened limit grooves, and a slider is slidably connected inside the limit groove. The sliding groove supports the receiving plate, and the limit groove restricts the movement range of the slider, thereby ensuring the stability of the receiving plate during device operation.

[0008] Preferably, one side of the slider is fixedly connected to one side of the receiving plate, and the slider extends above the base. The movement range of the slider is limited by the positioning groove, so that when the slider moves the receiving plate, the receiving plate can be prevented from falling off the base.

[0009] Preferably, a lower clamping plate is symmetrically fixedly connected to the upper surface of the base, a second spring is fixedly connected to the upper surface of the lower clamping plate, a bolt is threaded into the lower clamping plate, and a limit rod is fixedly connected to the upper surface of the lower clamping plate. The limit rod restricts the movement range of the upper clamping plate, and the limit rod is square, thereby preventing the upper clamping plate from rotating when it moves, thus improving the fixing strength to both sides of the PCB.

[0010] Preferably, an upper clamping plate is slidably connected to the limiting rod, one side of the upper clamping plate is fixedly connected to one end of the second spring, the bolt is threaded inside the upper clamping plate, and anti-slip pads are fixedly connected to one side of both the upper and lower clamping plates. The bolt is screwed into the upper and lower clamping plates to fix the position of the upper clamping plate, thereby fixing both sides of the PCB that need to be separated, and avoiding the impact on the separation quality due to PCB movement during the separation process.

[0011] Preferably, a support frame is fixedly connected to one side of the base, a cylinder is fixedly connected to the support frame, and a stamping plate is fixedly connected to the output end of the cylinder. After the PCB is fixed, the cylinder is started to drive the stamping plate to move down, so that the PCB can be separated.

[0012] The advantages of this invention are as follows: After the PCB is separated, it falls onto the separation plate. Because the water in the tank can submerge the PCB, it can separate the PCB from the debris on its surface. The debris falls into the bottom of the tank through the through holes on the separation plate. Then, the tank is pulled outward from the base, so that the separation plate is completely removed from the base. The separation plate is then lifted upward, so that it is removed from the tank. The PCB after separation can be collected from its surface. At the same time, because the debris settles at the bottom of the tank, it is ensured that the PCB after separation is in a clean state and does not need to be cleaned again afterward, thereby improving PCB processing efficiency.

[0013] This invention involves pulling the upper clamping plate upward along the limiting rod while simultaneously stretching the second spring. Then, the two sides of the PCB to be separated are inserted between the two sets of lower and upper clamping plates. The upper clamping plate is released, and the second spring retracts, causing the upper clamping plate to move downward, so that the two sets of anti-slip pads are in contact with the sides of the PCB. Finally, bolts are screwed into the upper and lower clamping plates to fix the sides of the PCB, thereby preventing the PCB from moving during the separation process and affecting the separation quality.

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a PCB separation device includes: a base 1, a first support groove 2 symmetrically formed inside the base 1, a fixing groove 3 symmetrically formed inside the first support groove 2, a water tank 4 movably connected inside the base 1, a second support groove 5 formed inside the water tank 4, a separation plate 6 placed on the second support groove 5, support rods 7 fixedly connected to both sides of the water tank 4, the support rods 7 slidably connected inside the first support groove 2, a positioning block 8 fixedly connected to one side of the support rod 7, the positioning block 8 slidably connected inside the first support groove 2, a fixing pad 9 fixedly connected to the upper surface of the positioning block 8, the fixing pad 9 movably connected inside the fixing groove 3, a first spring 10 fixedly connected to the inner wall of the fixing pad 9, one end of the first spring 10 fixedly connected to one side of the positioning block 8, a sliding groove 11 formed inside the base 1, a receiving plate 13 slidably connected inside the sliding groove 11, a limiting groove 12 symmetrically formed on the base 1, a slider 14 slidably connected inside the limiting groove 12, one side of the slider 14 fixedly connected to one side of the receiving plate 13, and the slider 14 extending above the base 1;

[0023] PCB depaneling is a crucial step in PCB manufacturing, affecting the PCB's electrical performance, mechanical strength, and appearance quality. Therefore, a PCB depaneling device is needed. In actual use, after depaneling, the PCB falls onto the receiving board 13. Two sets of sliders 14 are pulled to both sides along the limiting groove 12, causing the receiving board 13 to separate. The depaneled PCB above the receiving board 13 is blocked by the base 1 and falls onto the separation plate 6. Because the water in the water tank 4 can submerge the depaneled PCB, it can separate the PCB from its surface debris. The debris falls through the through holes on the separation plate 6 into the bottom of the water tank 4. Then, the water tank 4 is pulled outward from the base 1, causing the support rods 7 and positioning blocks 8 on both sides to move along the first support groove 2. This causes the fixing pad 9 to move from the rear fixing groove 3 to below the front fixing groove 3. Under the push of the first spring 10, the fixing pad 9 enters the front fixing groove 3, thus fixing the position of the water tank 4 and preventing the water tank 4 from falling out of the base 1. At the same time, the separating plate 6 is completely removed from the base 1. The separating plate 6 is lifted upwards and removed from the water tank 4, so that the PCB after separation can be collected. Since the debris settles at the bottom of the water tank 4, the PCB after separation is kept clean and does not need to be cleaned again, thereby improving the PCB processing efficiency. After the device is used, the water tank 4 is completely pulled out from the base 1, and the separation plate 6 and the inside of the water tank 4 can be cleaned for the next use.

[0024] Please see Figure 1-5As shown, a lower clamping plate 15 is symmetrically fixedly connected to the upper surface of the base 1. A second spring 16 is fixedly connected to the upper surface of the lower clamping plate 15. A bolt 17 is threadedly connected to the inside of the lower clamping plate 15. A limit rod 18 is fixedly connected to the upper surface of the lower clamping plate 15. An upper clamping plate 19 is slidably connected to the limit rod 18. One side of the upper clamping plate 19 is fixedly connected to one end of the second spring 16. The bolt 17 is threadedly connected to the inside of the upper clamping plate 19. Anti-slip pads 20 are fixedly connected to one side of both the upper clamping plate 19 and the lower clamping plate 15. A support frame 21 is fixedly connected to one side of the base 1. A cylinder 22 is fixedly connected to the support frame 21. A stamping plate 23 is fixedly connected to the output end of the cylinder 22.

[0025] Pull the upper clamping plate 19 upward along the limiting rod 18, while simultaneously stretching the second spring 16. Then, insert both sides of the PCB to be separated between the two sets of lower clamping plates 15 and the upper clamping plate 19. Release the upper clamping plate 19, and the tension on the second spring 16 decreases, causing it to retract. At the same time, the upper clamping plate 19 moves downward along the limiting rod 18, so that the two sets of anti-slip pads 20 are in contact with the sides of the PCB. Then, screw the bolts 17 into the upper clamping plate 19 and the lower clamping plate 15 to fix the position of the upper clamping plate 19, thereby fixing both sides of the PCB to be separated. This prevents the PCB from moving during the separation process and affecting the separation quality. After fixing the PCB, start the cylinder 22 to move the stamping plate 23 downward, and the PCB can be separated.

[0026] Working principle: The upper clamping plate 19 is pulled upward along the limiting rod 18, simultaneously stretching the second spring 16. Then, the two sides of the PCB to be separated are inserted between the two sets of lower clamping plates 15 and the upper clamping plate 19. The upper clamping plate 19 is released, and the second spring 16 retracts, causing the upper clamping plate 19 to move downward, so that the two sets of anti-slip pads 20 are in contact with the sides of the PCB. Then, bolts 17 are screwed into the upper clamping plate 19 and lower clamping plate 15 to fix the position of the upper clamping plate 19, thereby fixing the two sides of the PCB to be separated. The starting cylinder 22 drives the stamping plate 23 downward, thus performing the PCB separation operation. After the PCB is separated, it falls onto the receiving plate 13. The two sets of sliders 14 are pulled to both sides along the limiting groove 12, causing the receiving plate 13 to separate, thus completing the PCB separation. The PCB is blocked by the base 1 and falls onto the separation plate 6. Then, the water tank 4 is pulled out of the base 1, which drives the support rods 7 and positioning blocks 8 on both sides to move along the first support groove 2. This moves the fixing pad 9 from the rear fixing groove 3 to the front fixing groove 3, fixing the position of the water tank 4. The separation plate 6 is then lifted up, so that the separation plate 6 is removed from the water tank 4. The PCB after separation can be collected. Since the debris settles at the bottom of the water tank 4, the PCB after separation is kept clean and does not need to be cleaned again, thus improving the PCB processing efficiency. After the device is used, the water tank 4 is completely pulled out of the base 1, and the separation plate 6 and the inside of the water tank 4 can be cleaned for the next use.
