Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of PCB board separation devices, and in particular relates to a clamping and moving mechanism for a PCB board separation device. Background Technology
[0002] During PCB manufacturing, the PCB is split into multiple boards. A splitting device is used to cut the PCB and improve efficiency. A typical PCB splitting device includes a worktable with a rotatable serrated cutting blade and a pushing mechanism to move the PCB. The PCB is placed on the worktable, aligned with the cutting blade, and then the pushing mechanism moves the PCB to complete the splitting process.
[0003] In existing PCB board slitting devices with similar technical solutions, the pushing mechanism pushes the PCB board from one side during cutting. Since PCB boards are generally thin, the resistance of the cutting force can easily cause the PCB board to deform, so there is an urgent need to improve this. Utility Model Content
[0004] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a clamping and moving mechanism for a PCB board separating device, which solves the problem that the PCB board is easily deformed due to the obstruction of the cutting force when the PCB board is pushed to move in the existing separating device.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a clamping and moving mechanism for a PCB board separating device, set on the worktable of the separating device, includes a clamping plate, the clamping plate including an upper plate, a lower plate, a vertical plate and a rear plate, the upper plate and the lower plate are arranged in parallel, and the upper plate and the lower plate are connected on the right side by the vertical plate, the rear plate is connected and set on the rear side of the upper plate and the lower plate, and the net distance between the upper plate and the lower plate matches the thickness of the PCB board; the upper plate and the rear plate are provided with a notch near the left side to avoid the slitting blade, the notch is aligned with the slitting blade of the separating device, the top surface of the lower plate is provided with a slot at the position corresponding to the notch, and a removable material box is provided in the slot; the left side of the vertical plate is connected to a push plate that can move left and right through a telescopic component, and the clamping plate is set on the worktable that can move back and forth through a front and back moving mechanism.
[0006] As a further improvement of this utility model, the upper plate is made of a transparent material.
[0007] As a further improvement of this utility model, the bottom of the clamping plate is provided with multiple traveling wheels, and the worktable of the plate separating device is provided with a traveling rail that cooperates with the traveling wheels.
[0008] As a further improvement of this utility model, the front and rear moving mechanism includes a screw and a guide rod. The front and rear ends of the screw are rotatably mounted on the worktable of the plate separating device, and one end of the screw is connected to a motor that drives its rotation. The front and rear ends of the guide rod are fixedly mounted on the worktable of the plate separating device. Both the screw and the guide rod pass through the lower plate, and the screw is threadedly connected to the lower plate, while the guide rod is slidably connected to the lower plate.
[0009] As a further improvement of this utility model, a gap is provided between the bottom of the push plate and the lower plate.
[0010] As a further improvement of this utility model, a rubber pad is provided on the side of the push plate that contacts the PCB board.
[0011] As a further improvement of this utility model, the upper plate is provided with a plurality of adjusting bolts.
[0012] Compared with the prior art, this utility model has the following advantages: 1. By setting the clamping plate moving mechanism as a clamping plate structure, and the clamping plate includes an upper plate, a lower plate, a vertical plate, and a rear plate, with a notch on the upper plate and a slot on the lower plate corresponding to the notch, the PCB board can be directly inserted into the clamping plate during slitting, with the rear side of the PCB board pressing against the rear plate of the clamping plate. Then, the telescopic component drives the push plate to move, aligning the PCB board's slitting position with the slitting blade. At this point, the slitting blade can be opened, and the forward and backward moving mechanism can be activated. The forward and backward moving mechanism drives the clamping plate to move backward, completing the first slitting of the PCB board. When slitting again, the telescopic component continues to drive the push plate to move to the left, aligning the PCB board's second slitting position with the slitting blade, and then slitting is performed. For the third slitting, the second slitting steps are repeated, which is simple and convenient, avoiding the troublesome problems caused by repeated positioning.
[0013] In addition, during the slitting process, the upper and lower plates of the clamping plate have a clamping and limiting effect on the entire PCB board. Only the slitting position is provided with a notch to allow the slitting blade to pass. Therefore, the overall clamping effect on the PCB board is good, preventing the PCB board from deforming under the obstruction of cutting.
[0014] In addition, by setting a slot in the lower plate, interference with the slitting blade is avoided. A receiving box is set in the slot, so that the debris generated by slitting can be received, which helps to keep the worktable of the slitting device clean.
[0015] 2. By making the upper plate transparent, it is easy to observe the situation inside the clamping plate, thus facilitating operation.
[0016] 3. By setting multiple traveling wheels at the bottom of the clamping plate and setting a traveling rail on the worktable of the plate separating device, a certain amount of support and guidance can be provided for the bottom of the clamping plate, thus maintaining the accuracy of the clamping plate guidance.
[0017] 4. By setting the forward and backward movement mechanism as a screw, guide rod and motor mechanism, the motor is started and drives the screw to rotate. After the screw rotates, it will drive the clamping plate to move back and forth, which is simple and convenient to operate.
[0018] 5. By setting multiple adjusting bolts on the upper plate, when making slight adjustments to the thickness of the PCB board, the adjusting bolts can be turned so that the bottom of the adjusting bolt is above the PCB board, without restricting the movement of the PCB board and reducing the swaying of the PCB board in the vertical direction.
[0019] 6. By creating a gap between the bottom of the push plate and the lower plate, friction can be reduced and wear can be avoided. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.
[0022] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.
[0023] This utility model discloses a clamping and moving mechanism for a PCB board separating device. (Refer to...) Figure 1 and Figure 3A clamping and moving mechanism for a PCB board separating device is provided, mounted on the worktable 1 of the separating device, and includes a clamping plate 2. The cross-sectional shape of the clamping plate 2 is an inverted U-shape, such as... Figure 2 and Figure 3 As shown, the clamping plate 2 includes an upper plate 21, a lower plate 22, a vertical plate 23, and a rear plate 24. The upper plate 21 and the lower plate 22 are arranged in parallel, and their right sides are connected and fixed by the vertical plate 23. The rear plate 24 is fixedly connected to the rear side of the upper plate 21 and the lower plate 22. The net distance between the upper plate 21 and the lower plate 22 matches the thickness of the PCB board 8, and the net distance is generally set to 2mm. The standard thickness of the PCB board 8 is 1.6mm. The upper plate 21 and the rear plate 24 have a notch 25 near the left side to avoid the slitting blade 7. The notch 25 is aligned with the slitting blade 7 of the board separating device. The width of the notch 25 is preferably 3cm to leave slitting space. The top surface of the lower plate 22 has a slot 26 at a position corresponding to the notch 25. The width of the slot 26 is the same as the width of the notch 25. A removable material box 27 is placed within the slot 26. The material box 27 can be bolted to the slot 26 or attached to it with Velcro. A movable push plate 28 is connected to the left side of the vertical plate 23 via a telescopic member 29. A gap is provided between the bottom of the push plate 28 and the lower plate 22 to reduce friction and prevent wear. Furthermore, a rubber pad is provided on the side of the push plate 28 that contacts the PCB board 8. In this embodiment, the telescopic member 29 can be an electric push rod, with its extension rod fixed to the push plate 28. The clamping plate 2 is movable back and forth on the worktable 1 via a forward and backward moving mechanism 3.
[0024] In this embodiment, as Figure 1 As shown, the upper plate 21 can be made of transparent material, such as transparent PVC board, to facilitate observation of the situation inside the clamping plate 2, thereby facilitating operation.
[0025] In addition, such as Figure 1 As shown, the bottom of the clamping plate 2 is provided with multiple traveling wheels 4, and the worktable 1 of the separating device is fixedly provided with a traveling rail 5 that cooperates with the traveling wheels 4. By providing multiple traveling wheels 4 at the bottom of the clamping plate 2 and providing a traveling rail 5 on the worktable 1 of the separating device, a certain support and guidance can be provided for the bottom of the clamping plate 2, thus maintaining the guiding accuracy of the clamping plate 2.
[0026] In this embodiment, as Figure 1 and Figure 2As shown, the forward and backward moving mechanism 3 includes a screw 31 and a guide rod 32. The screw 31 is rotatably mounted on the worktable 1 of the separating device at both ends, and one end of the screw 31 is connected to a motor 33 that drives its rotation. The guide rod 32 is fixedly mounted on the worktable 1 of the separating device at both ends. Both the screw 31 and the guide rod 32 pass through the lower plate 22, and the screw 31 is threadedly connected to the lower plate 22, while the guide rod 32 is slidably connected to the lower plate 22. By configuring the forward and backward moving mechanism 3 as a mechanism of screw 31, guide rod 32, and motor 33, starting the motor 33 drives the screw 31 to rotate, which in turn drives the clamping plate 2 to move forward and backward, making operation simple and convenient.
[0027] In addition, the upper plate 21 is provided with a plurality of adjusting bolts 8; therefore, when the thickness of the PCB board 8 is slightly adjusted, the adjusting bolts 8 can be turned so that the bottom of the adjusting bolts 8 is above the PCB board 8, and the movement of the PCB board 8 is not restricted, thereby reducing the swaying of the PCB board 8 in the vertical direction.
[0028] This utility model sets the clamping plate 2 moving mechanism as the structure of the clamping plate 2, which includes an upper plate 21, a lower plate 22, a vertical plate 23, and a rear plate 24. The upper plate 21 has a notch 25, and the lower plate 22 has a slot 26 at the position corresponding to the notch 25. Therefore, during the cutting process, the PCB board 8 can be directly inserted into the clamping plate 2, with the rear side of the PCB board pressing against the rear plate 24 of the clamping plate 2. Then, the telescopic member 29 drives the push plate 28 to move, aligning the cutting position of the PCB board 8 with the cutting blade 7. At this time, the cutting blade 7 can be opened, and the front and rear moving mechanism 3 can be started. The front and rear moving mechanism 3 drives the clamping plate 2 to move backward, completing the first cutting of the PCB board 8. When cutting again, the telescopic member 29 continues to drive the push plate 28 to move to the left, aligning the second cutting position of the PCB board 8 with the cutting blade 7, and then cutting is performed. For the third cutting, the second cutting steps are repeated, which is simple and convenient, avoiding the troublesome problem caused by repeated positioning.
[0029] In addition, during the cutting process, the upper plate 21 and lower plate 22 of the clamping plate 2 have a clamping effect on the entire PCB board 8, and only allow the cutting blade 7 to pass at the cutting position. Therefore, the overall clamping effect on the PCB board 8 is good, preventing the deformation of the PCB board 8 caused by the cutting obstruction.
[0030] In addition, by setting a slot 26 on the lower plate 22, interference with the slitting blade 7 is avoided. A receiving box 27 is set in the slot 26, so that the debris generated by slitting can be received, which makes it easier to keep the worktable 1 of the slitting device clean.
