Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and in particular relates to a circuit board processing and dividing device. Background Art

[0002] When an integrated circuit board is being processed, the substrate of the circuit board must be cut before it can be put into use, and the cutting of the circuit board requires the use of a corresponding cutting device.

[0003] Chinese patent publication number CN220528294U discloses an integrated circuit board processing and segmenting device, comprising a support body, a slide bar, a segmenting assembly, and a positioning assembly. The support body is arranged in an I-shape, with slide bars positioned on either side of the support body. The segmenting assembly slides on the slide bars, and the positioning assembly is located on one side of the upper portion of the support body. A slide groove is provided in the middle of the support body. The positioning assembly includes a positioning frame, opposing screws, a moving block, a clamping block, a handle, a limit rod, a support spring, and a limit block. This device utilizes vertical rotary cutting, cutting from the side of the circuit board. This allows for clamping at the corners and center of the board, increasing segmentation stability.

[0004] However, in actual use, since the height of the cutting head is indirectly controlled by the pressing plate, and the spring will drive the cutting head away from the circuit board when there is no external force, the worker needs to keep pressing the pressing plate at all times during cutting, and the worker also needs to move the cutting head along the cutting direction. As a result, the worker not only needs to have close contact with the cutting head, but also needs to manually maintain the stability of the cutting device. This makes the device more dangerous and labor-intensive to use, and the method of moving the cutting head while keeping the height of the cutting head unchanged by manpower has poor stability. Utility Model Content

[0005] The utility model is intended to provide a circuit board processing and dividing device to solve the problems of the prior art mentioned above, such as high risk, high labor consumption and poor stability during use.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions: a circuit board processing and cutting device, including a processing table, and

[0007] A clamping mechanism is slidably arranged on the processing table and is used to clamp and limit the circuit board;

[0008] The control unit includes a first linear pair, a mounting frame, a second linear pair, and a lifting pair, wherein the first linear pair is mounted on the processing table, the mounting frame is mounted on the first linear pair, the second linear pair is arranged on the mounting frame, the first linear pair is perpendicular to the second linear pair, and the lifting pair is mounted on the second linear pair;

[0009] The cutting unit is installed at the bottom of the lifting pair.

[0010] The principle and effect of this technical solution:

[0011] 1. Through the joint arrangement of the first linear pair, the second linear pair and the lifting pair, the horizontal position and height of the cutting unit are controlled by the electrical control system, eliminating the need for manual control, thereby ensuring the safety of the cutting operation and eliminating the need for manual operation of the cutting unit position, saving manpower. At the same time, the movement of the cutting unit is mechanically controlled by the first linear pair, the second linear pair and the lifting pair, resulting in higher stability.

[0012] 2. The circuit board is clamped by a clamping mechanism to ensure the stability of the circuit board position.

[0013] The utility model is further configured as follows: the clamping mechanism includes a placing table, an adjusting unit and a baffle; the placing table is slidably arranged on the processing table; the baffle is L-shaped when viewed from above; and baffles are respectively arranged on all four sides of the placing table; the adjusting unit is installed in the placing table and is used to control the position of the baffle relative to the placing table.

[0014] The principle and effect of this technical solution: An adjustment unit controls the position of the surrounding baffles relative to the placement table, allowing them to abut the four corners of the circuit board on the placement table. This provides a clamping function for the circuit board, keeping it stable during cutting and applying no pressure after cutting, thus preventing the circuit board from being displaced or damaged by pressure.

[0015] The utility model is further configured as follows: the adjustment unit includes an adjustment head, a bidirectional screw and an adjustment plate. The interior of the placement table is provided with a sliding cavity. The bidirectional screw is rotatably installed in the sliding cavity, and one end of the bidirectional screw extends to the outside of the placement table and is connected to the adjustment head. Two adjustment plates are symmetrically arranged on the bidirectional screw, and the adjustment plates slide in cooperation with the sliding cavity. A transmission plate is fixed to the inner side of the baffle, and the end of the transmission plate extends into the sliding cavity and slides in cooperation with the side of the adjustment plate away from the center of the placement table. The transmission plate is arranged obliquely relative to the adjustment plate.

[0016] The principle and effect of this technical solution: the rotation of the bidirectional screw can be controlled by rotating the adjusting head, and the rotation of the bidirectional screw can drive the two adjusting plates to move closer or farther away from each other, and the transmission plate and the adjusting plate slide together, and the transmission plate is tilted relative to the adjusting plate. At the same time, the movement of the transmission plate is restricted by the placement table, and thus a crank slider structure is formed between the transmission plate, the bidirectional screw and the adjustment plate. The baffle can be indirectly controlled to move closer to or away from the four sides of the placement table through the adjusting head, and then the internal dimensions between the baffles can be changed synchronously by synchronously controlling the baffle to move closer to or away from the placement table, so that the placement table can adapt to the sizes of circuit boards of different sizes, and can abut and clamp circuit boards of different sizes on all sides.

[0017] The utility model is further configured as follows: an air suction hole is opened on the placement table.

[0018] The principle and effect of this technical solution: the setting of the suction hole enables the installation of a suction pipe inside the placement table, and the suction pump is connected to the outside. The suction pump provides suction, so that the circuit board is firmly adsorbed on the placement table, thereby improving the stability of the circuit board placed on the placement table. After being divided, the adsorption force of the suction hole can keep the divided circuit board in a stable state, thereby improving the stability of the circuit board placement.

[0019] The utility model is further configured as follows: notches are respectively opened on the four sides of the top of the placement table, a load-bearing plate is fixed on the inner side of the baffle, the load-bearing plate is adapted to the notches, and the top surface of the load-bearing plate is flush with the top surface of the placement table.

[0020] The principle and effect of this technical solution: through the setting of the notch and the load-bearing plate, the load-bearing plate can move along with the movement of the baffle, and therefore, regardless of the size of the circuit board, the baffle can not only abut and block the side panels of the circuit board, but also provide support for the circuit board through the load-bearing plate, so that the circuit board can remain stable relative to the placement table after being divided, thereby avoiding the situation where the circuit board tips over from the placement plate after being divided, and improving the stability of the placement table in clamping and placing the circuit board.

[0021] The utility model is further configured as follows: the first linear pair includes an electric slide rail, the cross section of the mounting frame is in an inverted U shape, the electric slide rails are respectively installed on both sides of the processing table, and the bottom of the side wall of the mounting frame is connected to the electric slide rails.

[0022] The principle and effect of this technical solution are as follows: the mounting frame is driven to move as a whole by an electric slide rail, so that the mounting frame can drive the cutting unit to move horizontally in one direction, thereby completing the function of dividing the circuit board on the clamping mechanism in this direction, and cooperating with the second straight line pair so that the cutting unit can move in a certain direction on the plane to complete the cutting of the circuit board.

[0023] The utility model is further configured as follows: the second linear pair includes a reciprocating motor, a reciprocating screw and a slider; the cross-section of the mounting frame is an inverted U-shape; a slide groove is provided on the top of the mounting frame; the reciprocating screw is rotatably installed in the slide groove; the reciprocating motor is fixed to the outer wall of the mounting frame; one end of the reciprocating screw extends to be connected to the movable end of the reciprocating motor; the slider slides in the slide groove; the slider is threadedly mounted on the reciprocating screw; and the lifting pair is connected to the slider.

[0024] The principle and effect of this technical solution: the reciprocating screw is driven to rotate by a reciprocating motor, and the slider is respectively matched with the slide and the reciprocating screw, and then the reciprocating motor can control the slider to reciprocate along the slide, thereby driving the lifting pair and the cutting unit to reciprocate horizontally and linearly, so that the cutting unit can move in a specified direction to complete the cutting of the circuit board on the clamping mechanism, and cooperate with the first linear pair to enable the cutting unit to move in a certain direction on the plane to complete the cutting of the circuit board.

[0025] The utility model is further configured as follows: the lifting pair includes a mounting plate, a lifting motor, a lifting screw, a top plate, a lifting rod, a bottom plate and a limit block; the mounting plate is mounted on the second linear pair; the lifting motor is fixed on the mounting plate; the lifting rod is slidably inserted on the mounting plate; the top plate is fixed to the top of the lifting rod; the bottom plate is fixed to the bottom of the lifting rod; the lifting screw is threadedly inserted on the top plate; the top of the lifting screw is fixed to the limit block; the bottom of the lifting screw is connected to the movable end of the lifting motor; and the cutting unit is mounted on the bottom plate.

[0026] The principle and effect of this technical solution: the top plate and the bottom plate are connected by a lifting rod, so that the top plate and the bottom plate can be lifted and lowered relative to the mounting plate, and at the same time the lifting rod can also guide and limit the movement of the top plate and the bottom plate, so that the cutting unit can only move up and down under the action of the lifting pair, and the lifting screw is controlled to rotate by the lifting motor, and then the lifting screw can drive the top plate to move along the lifting screw, thereby controlling the height of the cutting unit.

[0027] The utility model is further configured as follows: the cutting unit comprises a cutting motor and a cutting head, the cutting motor is fixed to the top of the base plate, the top of the cutting head passes through the base plate and is connected to the movable end of the cutting motor.

[0028] The principle and effect of this technical solution: by installing the cutting motor and the cutting head on the base plate, the height of the cutting motor and the cutting head relative to the base plate will not change, so that the torque and other resistances experienced by the cutting motor during cutting will not change, thereby protecting the cutting head and the cutting motor, and the cutting motor can always be stably connected to the base plate.
