Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically to a positioning reference compensation cutting machine for PCB copper-clad laminates. Background Technology

[0002] The positioning reference compensation cutting machine for PCB copper-clad laminates is a key piece of equipment in the PCB (Printed Circuit Board) production process for precisely cutting copper-clad laminates. As the basic material for PCB manufacturing, copper-clad laminate is made by impregnating reinforcing materials such as electronic fiberglass cloth with resin, and then hot-pressing one or both sides with copper foil. It has a significant impact on PCB performance.

[0003] Before cutting PCB copper-clad laminates, positioning blocks are needed to determine the reference. However, during transportation or stacking, copper-clad laminates are prone to edge warping and local corner bending (especially thin copper-clad laminates). Traditional fixing blocks cannot make the deformed parts fit the reference, resulting in positioning deviation and a high rate of dimensional deviation after cutting. If the copper-clad laminate is directly pressed and reset with force, it is easy to cause the copper-clad laminate to crack. Therefore, a positioning reference compensation cutting machine for PCB copper-clad laminates is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a positioning reference compensation cutting machine for PCB copper-clad laminates, which solves the problem that in the prior art, PCB copper-clad laminates need to rely on positioning blocks to determine the reference before cutting. However, during the transportation or stacking of copper-clad laminates, edge warping and local corner bending are easy to occur (especially for thin copper-clad laminates). Traditional fixing blocks cannot make the deformed parts fit the reference, resulting in positioning deviation and a high rate of dimensional deviation after cutting. If the copper-clad laminate is directly pressed and reset with hard force, it is easy to cause the copper-clad laminate to crack.

[0005] This utility model provides the following technical solution: a positioning reference compensation cutting machine for PCB copper-clad laminate, including a processing table, two sets of symmetrically arranged mounting brackets fixedly connected to the bottom end of the processing table, two sets of straight grooves opened at the top end of the processing table, a cutting machine fixedly connected to the top end of the processing table, a translation component provided between the inner side of each mounting bracket and the top end of each straight groove, a rotation component provided at the top end of each translation component, a clamping component provided at the outer end of each rotation component, and a pressing component provided at the top end of each clamping component.

[0006] As a preferred embodiment of the above technical solution, the translation component includes a cylinder, which is fixedly installed on the inner side of the mounting frame. A connecting plate is installed on the telescopic end of the cylinder, and the top end of the connecting plate is inserted into a straight groove. A mounting box is fixedly connected to the top end of the connecting plate.

[0007] As a preferred embodiment of the above technical solution, the rotating assembly includes a motor, which is fixedly installed on the outer side of the mounting box. A bidirectional threaded rod is installed on the output end of the motor, and the side end of the bidirectional threaded rod is rotatably disposed on the inner side of the mounting box. A guide rod is fixedly connected between the inner sides of the mounting box.

[0008] As a preferred embodiment of the above technical solution, the clamping assembly includes two sets of threaded sleeves, both sets of threaded sleeves are threaded to the outer end of the bidirectional threaded rod, the side end of each threaded sleeve is sleeved on the outer end of the guide rod, and a right-angle clamp is fixedly connected to the side end of each threaded sleeve.

[0009] As a preferred embodiment of the above technical solution, the pressure-reducing assembly includes a second cylinder, which is fixedly installed on the top of the right-angle clamp, and a pressure plate is installed on the telescopic end of the second cylinder.

[0010] As a preferred embodiment of the above technical solution, a rubber pad is fixedly connected to the bottom end of the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention involves placing the copper-clad laminate on the processing table, activating the inner translation component of the mounting frame, which drives the top rotating component to move along the straight groove to the edge of the board. The rotating component drives the clamping component to clamp the board for initial positioning.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: a positioning reference compensation cutting machine for PCB copper-clad laminates, including a processing table 1, two sets of symmetrically arranged mounting brackets 101 fixedly connected to the bottom end of the processing table 1, two sets of straight grooves 102 opened at the top end of the processing table 1, a cutting machine 2 fixedly connected to the top end of the processing table 1, a translation component 3 provided between the inner side of each mounting bracket 101 and the top end of each straight groove 102, a rotation component 4 provided at the top end of each translation component 3, and the outer end of each rotation component 4... Each component is equipped with a clamping assembly 5, and each clamping assembly 5 has a pressing assembly 6 at its top. By placing the copper-clad board on the processing table 1, the inner translation assembly 3 of the mounting frame 101 is activated, which drives the top rotating assembly 4 to move along the straight groove 102 to the edge of the board. The rotating assembly 4 drives the clamping assembly 5 to clamp the board and initially position it. If the board is warped, the pressing assembly 6 on the clamping assembly 5 is activated to flexibly flatten the deformed area to prevent cracking, thus solving the traditional positioning deviation problem. Then the cutting machine 2 cuts according to the program, and the board is stable without deviation, reducing the dimensional deviation rate.

[0016] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, the translation component 3 includes a cylinder 301, which is fixedly installed on the inner side of the mounting frame 101. A connecting plate 302 is installed on the telescopic end of the cylinder 301. The top of the connecting plate 302 is inserted into the straight groove 102. A mounting box 303 is fixedly connected to the top of the connecting plate 302. In practice, when the PCB copper-clad laminate positioning reference compensation cutting machine is operating, the copper-clad laminate to be processed is first placed stably on the top of the processing table 1 to ensure that the board is roughly centered. Then, the translation components 3 in the two sets of symmetrical mounting frames 101 at the bottom of the processing table 1 are started. After the cylinder 301 of each set of translation components 3 is powered on, the telescopic end pushes the connecting plate 302 fixed thereto and slides smoothly along the straight groove 102 at the top of the processing table 1. The mounting box 303 welded to the top of the connecting plate 302 moves synchronously with it until the two sets of mounting boxes 303 reach the left and right edges of the copper-clad laminate respectively and are matched with the edge spacing of the board, thus finding the initial position for the clamping action.

[0017] As one implementation method in this embodiment, such as Figure 1 and Figure 2As shown, the rotating assembly 4 includes a motor 401, which is fixedly mounted on the outer side of the mounting box 303. A bidirectional threaded rod 402 is mounted on the output end of the motor 401. The side end of the bidirectional threaded rod 402 is rotatably disposed on the inner side of the mounting box 303. A guide rod 403 is fixedly connected between the inner sides of the mounting box 303. The clamping assembly 5 includes two sets of threaded sleeves 501, both sets of which are threadedly connected to the outer end of the bidirectional threaded rod 402. The side end of each threaded sleeve 501 is sleeved on the outer end of the guide rod 403. All are fixedly connected with right-angle clamps 502. During implementation, the rotating component 4 on the outside of the mounting box 303 is started. The output end of the motor 401 drives the internal bidirectional threaded rod 402 to rotate. Since the screw sleeve 501 is fitted on the guide rod 403 inside the mounting box 303, the guide rod 403 restricts the circumferential rotation of the screw sleeve 501. The rotation of the bidirectional threaded rod 402 is converted into the relative movement of the two sets of screw sleeves 501 along the guide rod 403. The right-angle clamps 502 on the side of the screw sleeve 501 move closer and slowly clamp the copper-clad plate from both sides to achieve initial positioning and prevent the overall displacement of the plate during subsequent processing.

[0018] As one implementation method in this embodiment, such as Figure 4 As shown, the pressing component 6 includes a second cylinder 601, which is fixedly installed on the top of the right-angle clamp 502. The telescopic end of the second cylinder 601 is equipped with a pressing plate 602, and the bottom end of the pressing plate 602 is fixedly connected to a rubber pad 603. In practice, if the copper-clad laminate has edge warping or local folding, the pressing component 6 at the top of the corresponding right-angle clamp 502 is activated. The telescopic end of the second cylinder 601 pushes the pressing plate 602 down. The rubber pad 603 (a highly elastic material that can buffer pressure) at the bottom end of the pressing plate 602 first contacts the deformed part. As the second cylinder 601 applies force, the rubber pad 603 transmits force evenly through elastic deformation, flexibly flattening the deformed part, so that the edge of the board fits the positioning reference. This avoids cracking caused by traditional hard pressing and solves the positioning deviation problem of the fixed stop not being able to adapt to the deformation.

[0019] Working principle: When the PCB copper clad laminate positioning reference compensation cutting machine is working, the copper clad laminate to be processed is first placed stably on the top of the processing table 1 to ensure that the board is roughly centered. Then, the translation components 3 in the two sets of symmetrical mounting frames 101 at the bottom of the processing table 1 are started. After the cylinder 301 of each set of translation components 3 is powered on, the telescopic end pushes the connecting plate 302 fixed thereto and slides smoothly along the straight groove 102 at the top of the processing table 1. The mounting box 303 welded to the top of the connecting plate 302 moves synchronously with it until the two sets of mounting boxes 303 reach the left and right edges of the copper clad laminate respectively and match the distance between the edges of the board, thus finding the initial position for the clamping action.

[0020] Next, the rotating assembly 4 on the outside of the mounting box 303 is started. The output end of the motor 401 drives the internal bidirectional threaded rod 402 to rotate. Since the threaded sleeve 501 is fitted on the guide rod 403 inside the mounting box 303, the guide rod 403 restricts the circumferential rotation of the threaded sleeve 501. The rotation of the bidirectional threaded rod 402 is converted into the relative movement of the two sets of threaded sleeves 501 along the guide rod 403. The right-angle clamping plate 502 on the side of the threaded sleeve 501 moves closer and slowly clamps the copper-clad plate from both sides to achieve initial positioning and prevent the overall displacement of the plate during subsequent processing.

[0021] If the copper-clad laminate has warped edges or localized bends, the pressing component 6 at the top of the corresponding right-angle clamp 502 is activated. The telescopic end of cylinder 2 601 pushes the pressing plate 602 downward. The rubber pad 603 (a highly elastic material that can buffer pressure) at the bottom of the pressing plate 602 first contacts the deformed part. As cylinder 2 601 applies force, the rubber pad 603 transmits force evenly through elastic deformation, flexibly flattening the deformed part and making the edge of the board fit the positioning reference. This avoids cracking caused by traditional hard pressing and solves the positioning deviation problem caused by the fixed stop not being able to adapt to the deformation.

[0022] Once the positioning compensation is complete, the cutting machine 2 at the top of the processing table 1 is started to cut the copper-clad board according to the preset program. At this time, the board is firmly clamped and the deformation has been compensated. There is no offset during cutting, which greatly reduces the dimensional deviation rate. After processing, each component is reversed and reset. The pressure plate 602 moves up, the right angle clamp 502 is released, and the mounting box 303 returns to the initial position, which facilitates quick replacement of new boards. The whole process is automated, which reduces human error, shortens the processing cycle, and balances cutting accuracy and efficiency, effectively solving the core shortcomings of traditional cutting.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
