[0002] Nowadays, LED lamps have become the mainstream of lighting. Lighting up LED lamp beads requires LED driving circuits. Generally, LEDs use small LED lamp circuits to achieve constant voltage drive, constant current drive, PWM drive, etc.

[0003] When producing LED lamp circuit boards, sometimes it is necessary to separate a circuit board into two or more pieces according to reasonable lines without affecting its effectiveness. Cutting circuit boards is the basis of PCBA processing. Sometimes, in the production process, it is necessary to divide a large circuit board into multiple small circuit boards. The circuit boards are adhered by residual materials. At this time, the board separator can come in handy. The board separator can cut off the residual materials connected by the large circuit board and separate it into multiple small circuit boards, thereby facilitating subsequent process processing and production. When conventional circuit boards are cut, the residual materials adhering between the small circuit boards need to be cut off. After the residual materials are cut off, the small circuit boards are detached. When cutting, the detached circuit boards will be mixed with the cut circuit board residual materials. When people take away the cut circuit boards, they need to remove the mixed residual materials first, which is more troublesome.

[0004] In view of this, the utility model provides a plate slitting device for an LED circuit board which can cut off the residual material adhered to the circuit board at the same time, separate the residual material and the circuit board, avoid mixing the residual material and the circuit board, eliminate the need for secondary cleaning, and improve the slitting efficiency.

DETAILED DESCRIPTION

[0019] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0020] Embodiment 1: A plate cutting device for LED circuit board, such as Figure 1-5As shown, it includes a base 1, a cavity 2, a discharge plate 3, a discharge trough 31, a shell 4, a connecting plate 5, an electric slide rail 6, a guide rail 7, a guide groove 71, a connecting block 8, a cutting machine 81 and an adjusting rod 9. The base 1 is provided with a cavity 2, and a discharge plate 3 is welded on the upper part of the base 1. The discharge plate 3 is provided with a discharge trough 31. The cut surplus material will be separated from the circuit board on the discharge plate 3 through the discharge trough 31. The upper part of the discharge plate 3 is provided with a groove for limiting the moving position of the circuit board. The top of the base 1 is fixedly installed with a shell 4, and the shell 4 is made of a material with higher hardness and can provide better supporting force. The discharge plate 3 passes through the lower part of the shell 4, and the lower part of the shell 4 contacts with the top of the discharge plate 3. The discharge plate shell 4 is fixedly connected to the rear side of the connection plate 5, and the front of the connection plate 5 is connected to the electric slide rail 6. The electric slide rail 6 is composed of a driving motor, a transmission screw and a support The housing 4 is composed of a transmission motor on the electric slide 6, which is installed at the rear of the connecting plate 5. The output shaft of the transmission motor passes through the connecting plate 5 and is connected to the transmission screw in the support frame of the electric slide 6. The transmission screw of the electric slide 6 is threadedly connected with a sliding block 61, and the sliding block 6 will move with the movement of the electric slide 6. Two guide rails 7 are connected to the left and right sides of the sliding block 6. The two guide rails 7 are arranged in a front-to-back staggered manner at the same height. Connecting blocks 8 are slidably provided in the guide rails 7, and cutting machines 81 are installed on the connecting blocks 8. Adjusting rods 9 are rotatably provided in the guide rails 7, and the adjusting rods 9 are inserted into the connecting blocks 8 in the guide rails 7 on the same side. Rotating the adjusting rods 9 can adjust the position of the connecting blocks 8 between the guide rails and are threadedly connected to the connecting blocks 8. Guide grooves 71 are provided on the left and right sides of the upper part of the housing 4, and the adjusting rods 9 slide in the guide grooves 71 as the guide rails 7 on the sliding block move.

[0021] Before processing and cutting, the circuit board is processed and divided into multiple individual small circuit boards from a whole circuit board. The individual circuit boards are arranged in multiple pieces of leftover materials for cutting. Usually, there are horizontal or vertical rows between the small circuit boards, and one of the rows is not adhered to each other, and the other side is connected by leftover materials. At this time, when people cut off the leftover materials between each horizontal row or each vertical row of the whole circuit board, the whole row of small circuit boards at the adhesion will all fall off individually. Initially, the distance between the two cutting machines 81 is adjusted according to the size of the individual small circuit boards on the whole circuit board: turn the adjusting rod 9, the connecting block 8 threaded on the adjusting rod 9 will move its position, and the distance between the two cutting machines 81 is adjusted by adjusting the two adjusting rods 9. , to ensure that the distance between the two cutting machines 81 is just consistent with the size of the long side or wide side of the small circuit board, the sliding block 61 is located at the rear position of the electric slide rail 6, and the whole circuit board to be cut is placed on the discharge plate 3. It should be noted that the placement direction of the whole circuit board placed on the discharge plate 3 is consistent with the direction of the residual material adhesion position and the cutting direction of the cutting machine 81. The circuit board on the discharge plate 3 is pushed into the housing 4. When the positions of the two cutting machines 81 are exactly opposite to the residual material adhesion on both sides of the circuit board to be cut, the two cutting machines 81 are started, and the cutting machines 81 rotate, and then the transmission motor on the electric slide rail 6 is started, and the transmission motor is controlled to rotate forward, driving the sliding block 61 on the electric slide rail 6 to move forward, so that The connecting block 8 and the cutting machine 81 on the sliding block 61 are driven to move forward, and the adjusting rod 9 connected to the guide rail 7 will slide in the guide groove 71 with the movement of the sliding block 61. Since the cutting machine 81 on the right is at a slightly forward position at the same height as the cutting machine 81 on the left, when the left side of the single small circuit board block has completely cut off the left side, the cutting machine 81 on the left has not yet cut off all the left materials connected to the same small circuit board. This is beneficial to avoid cutting off the left materials at the same time during cutting. When the small circuit board falls off, it may be driven by the rotational potential energy of the two rotating cutting machines 81, and then bounce up and hit other parts of the device, causing damage to the cut circuit board. When the sliding block 61 on the electric slide rail 6 moves to the front, the control The electric slide rail 6 stops, and the cutter 81 on the right will cut off the remaining material adhering to the small circuit board in one piece. The cut remaining material will fall into the cavity 2 in the base 1 through the discharge chute 31. The cutter 81 on the left will cut off the entire row of small circuit boards and separate them into individual grooves on the discharge plate 3. At this time, people will push the entire circuit board to be cut to the right to the same position as the previous cutting. The cut small circuit board will be pushed out of the shell 4 on the discharge plate 3, and then the transmission motor on the electric slide rail 6 is controlled to reverse, driving the sliding block 61 to move backward, and the circuit board will continue to be cut by the rotating cutter 81. Repeat the above cutting steps. After the cutting is completed, the electric slide rail 6 and the two cutters 81 are turned off.

[0022] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a lower hopper 10 is also included. The rear of the discharge plate 3 is connected to the lower hopper 10, and the front of the lower hopper 10 is connected to the base 1. The lower hopper 10 is arranged in a high rear and low front shape, so that the cut residual materials can slide out of the device through the lower hopper 10, which is convenient for collection and cleaning.

[0023] like Figure 2 As shown, it also includes a connecting frame 11, the bottom of the electric slide rail 6 is firmly welded with the connecting frame 11, and the lower part of the connecting frame 11 is rotatably connected to no less than three rollers 12. The rollers 12 will contact the surface of the circuit board on the discharge plate 3 and can stabilize the circuit board being cut.

[0024] When the circuit board is pushed into the shell 4 on the discharge plate 3, the top side of the circuit board will contact the roller 12. When the two cutting machines 81 are working, the roller 12 connected to the connecting frame 11 can stabilize the circuit board being cut to prevent the small circuit board from being displaced by force during cutting, thereby affecting the cutting effect. The remaining material cut off by the right cutting machine 81 will fall into the lower hopper 10 below through the lower chute 31, and the remaining material will slide from the inclined lower hopper 10 to the outside of the device for easy collection and cleaning.

[0025] In a preferred embodiment, the unloading plate 3 is made of a soft colloid material, which causes less damage to the sliding surface of the circuit board.

[0026] In a preferred embodiment, the electric slide rail 6 runs smoothly without shaking, so as to avoid the cutting machine 81 being shaken by force during cutting, thereby affecting the cutting effect.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
