Description

Technical Field

[0001] The present application belongs to the technical field of copper foil detection, and in particular relates to a cutting sampler and a cutting method for copper foil detection. Background Art

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate of the circuit board, which serves as the conductor of the PCB. It is easy to adhere to the insulating layer, accept the printed protective layer, and form a circuit pattern after corrosion.

[0003] In order to ensure that the copper foil meets the standards during the production process, testing is required. During the testing, cutting and sampling are required, and then the samples are tested. The existing cutting sampler (for example: CN218098360U) can only take one sample at a time, and the sampling efficiency is low. If the middle position of the copper foil needs to be sampled, two cutting operations are required in succession, which is inconvenient to operate. The two cutting operations are performed separately, which is prone to the phenomenon of copper foil adhesion, displacement and dislocation. Therefore, it is necessary to develop a new cutting sampler for copper foil testing. Summary of the invention

[0004] The purpose of the present application is to provide a cutting sampler and cutting method for copper foil detection, so as to solve the problem that the existing cutting sampler proposed in the above background technology can only take one sample at a time, the sampling efficiency is low, and if the middle position of the copper foil needs to be sampled, two cutting operations are required in succession, which is inconvenient to operate, and the two cutting operations are carried out separately, which is easy to cause the copper foil to stick, deviate and misalign.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A cutting sampler for copper foil detection comprises a sampling base, wherein the upper surface of the sampling base is provided with a plurality of clamping frames, a clamping screw is threadedly mounted on the clamping frame, a handle and a clamping plate are respectively mounted on the top and bottom ends of the clamping screw, and two clamping frames opposite to each other are used in cooperation with each other, wherein a plurality of the clamping frames on one side are fixedly mounted on the upper surface of the sampling base, wherein the clamping frames on the other side are movably mounted on the upper surface of the sampling base, a sliding plate is fixedly mounted on the side surface of the movably mounted clamping frame, a sliding frame is slidably mounted on the outer surface of the sliding plate, the sliding frame is fixedly mounted on the upper surface of the sampling base, a sliding locking rod is slidably mounted on the sliding frame, and the top end of the sliding locking rod is fixedly mounted on the upper surface of the sampling base An operating disk is installed, a plurality of sliding locking grooves are opened on the surface of the sliding plate, the bottom end of the sliding locking rod is inserted into the inner wall of the sliding locking groove, a lower support seat is movably provided on the side of the sampling base, a locking bolt is threadedly installed on the lower support seat, and the tail end of the locking bolt is in contact with the side of the sampling base, an upper support frame is rotatably installed on the lower support seat, a two-way threaded rod is rotatably installed on the inner wall of the upper support frame, a handwheel is fixedly installed on one end of the two-way threaded rod, threaded plates are threadedly installed on the outer surfaces of two sections of the threads of the two-way threaded rod, a connecting plate is fixedly installed on the side of the threaded plate, a tool protection shell is fixedly installed on the side of the connecting plate, and a sampling knife is movably arranged in the tool protection shell.

[0007] By adopting the above scheme, a sampling base is set to be used in conjunction with multiple pressing frames, and two pressing frames opposite to each other on the left and right are used in conjunction with a pressing screw and a pressing plate, so that the pressing operation of multiple copper foil strips can be realized, and the up and down movement of the sampling knife is used to realize the synchronous cutting and sampling of multiple samples, thereby improving the cutting and sampling efficiency, and the upper support frame is used in conjunction with the lower support seat, and the lower support seat can be adjusted in position by moving left and right, and used in conjunction with two sampling knives, the middle position of the copper foil can be sampled, and the sampling position is adjustable. By movably setting the pressing frame on one side on the sampling base, the distance between the two pressing frames opposite to each other on the left and right can be adjusted to meet the needs of different lengths. The copper foil strip is pressed and fixed for use, which improves the universality of use. By setting a two-way threaded rod in conjunction with a threaded plate, the distance between the two tool protection shells can be adjusted, and then the distance between the two sampling knives can be adjusted to meet the use of sampling lengths of different lengths, and the upper support frame can be rotated relative to the lower support seat. When placing the copper foil strip, the lower support seat is rotated and opened for easy operation. By setting a tool protection shell in conjunction with a sliding column and a spring, the tool protection shell has a protective effect on the sampling knife, avoiding the safety hazard of the sampling knife outer packaging. When cutting is required, the sampling knife moves downward out of the tool protection shell to achieve sampling, which is easy to operate.

[0008] As a preferred embodiment, an L-shaped slide bar is fixedly installed on the side of the movable pressing frame, and an L-shaped slide groove for the L-shaped slide bar to slide is provided on the upper surface of the sampling base.

[0011] By adopting the above scheme, spring one is provided, and when the sliding lock rod is disengaged from the sliding lock slot, spring one is deformed. Therefore, the elastic force of spring one can be used to drive the sliding lock rod to slide back and insert into the sliding lock slot, thereby improving the convenience of the sliding locking operation.

[0013] By adopting the above solution, the trapezoidal slide bar is used in conjunction with the trapezoidal slide groove, which can ensure the stable sliding of the lower support seat and avoid separation between the lower support seat and the sampling base.

[0014] As a preferred implementation, a limit plate is fixedly mounted on the side of the upper support frame, and the limit plate is arranged in close contact with the upper surface of the sampling base.

[0015] By adopting the above solution, the setting of the limiting plate can play a supporting effect, so that the upper support frame can maintain good position stability.

[0016] As a preferred implementation, a plurality of guide rods are fixedly mounted on the inner wall of the upper support frame, and the threaded plate is slidably mounted on the outer surfaces of the plurality of guide rods.

[0017] By adopting the above scheme, the setting of the guide rod plays a supporting and guiding effect on the threaded plate, which can prevent the threaded plate from moving, shaking and tilting under the rotation of the bidirectional threaded rod, thereby ensuring the good levelness of the tool protective shell.

[0018] As a preferred embodiment, a plurality of sliding columns are slidably installed on the upper surface of the tool protection shell, an operating plate is fixedly installed on the top of the sliding column, the bottom end of the sliding column is fixedly connected to the sampling knife, and a plurality of springs are fixedly installed between the operating plate and the tool protection shell.

[0019] By adopting the above scheme, by pressing the operating panel downward, the sliding column can be driven to drive the sampling knife to move downward and out of the tool protective shell, thereby realizing cutting and sampling. At this time, spring 2 is deformed, so after releasing the pressure on the operating panel, the elastic force of spring 2 can be used to drive the sampling knife to quickly reset and retract into the tool protective shell, thereby improving the convenience of operation.

[0020] A copper foil cutting method, which uses the aforementioned cutting sampler for copper foil detection to cut the copper foil, comprises the following steps:

[0021] S100, when in use, first rotate and unfold the upper support frame, so that the upper support frame rotates to the upper part of the upper support frame and is offset from the sampling base;

[0022] S200, then adjust the position of the movable clamping frame according to the length of the copper foil strip to be cut and sampled, pull the operating disk during adjustment, the operating disk drives the sliding lock rod to move out of the sliding lock slot, at this time the spring 1 is deformed and the movable clamping frame is unlocked, the movable clamping frame is supported to move left and right to adjust the position, after adjusting to the desired position, release the operating disk, use the elastic force of the spring 1 to drive the sliding lock rod to reset and insert it into the relative sliding lock slot to achieve locking;

[0023] S300, then put the two ends of the copper foil strip into the left and right opposite pressing frames in turn, rotate the pressing screw to drive the pressing plate to move downward, so as to achieve the pressing and fixing of the copper foil strip;

[0024] S400, then adjust the sampling position according to the sampling needs, screw out the locking bolt during adjustment, then the lower support seat is unlocked and can slide left and right, after sliding to the desired position, screw in the locking bolt, then the lower support seat is locked;

[0025] S500, then reversely rotating the upper support frame so that the upper support frame rotates until the tool protection shell is located directly above the sampling base;

[0026] S600, then the distance between the two sampling knives is adjusted according to the sampling length. During the adjustment, the bidirectional threaded rod is rotated to drive the two threaded plates to be relatively close to or away from each other, thereby driving the two tool protection shells to be relatively close to or away from each other, thereby achieving the distance adjustment between the sampling knives in the two tool protection shells. After the adjustment is completed, the rotation of the bidirectional threaded rod is stopped;

[0027] S700, then press the operation panel with both hands respectively, the operation panel drives the sliding column to move downward, and then drives the sampling knife to move downward to achieve sampling. After the sampling is completed, release the operation panel with your hands. At this time, the elastic force of spring 2 will drive the sampling knife to move upward and reset it into the tool protection shell.

[0028] Compared with the prior art, the beneficial effects of this application are:

[0029] The cutting sampler for copper foil detection is used by arranging a sampling base to cooperate with multiple pressing frames, and using two pressing frames opposite to each other on the left and right to cooperate with a pressing screw and a pressing plate, so as to realize the pressing operation of multiple copper foil strips, and realize the synchronous cutting and sampling of multiple samples by using the up and down movement of the sampling knife, thereby improving the cutting and sampling efficiency, and using the upper support frame to cooperate with the lower support seat, the lower support seat can be adjusted in position left and right, and used with two sampling knives, the middle position of the copper foil can be sampled, and the sampling position is adjustable;

[0030] The cutting sampler for copper foil detection is configured such that a pressing frame on one side is movably arranged on a sampling base, so that the distance between the two pressing frames opposite to each other on the left and right sides can be adjusted, which satisfies the need for pressing and fixing copper foil strips of different lengths, thereby improving universality of use. By arranging a bidirectional threaded rod in conjunction with a threaded plate, the distance between the two tool protection shells can be adjusted, thereby adjusting the distance between the two sampling knives, which satisfies the need for sampling of different lengths. The upper support frame can be rotated relative to the lower support seat, and the lower support seat can be rotated and opened when placing the copper foil strip, which is convenient for operation.
