Description

Technical Field

[0001] This utility model relates to the technical field of circuit board conveying devices, and in particular to circuit board processing and transmission devices. Background Technology

[0002] Circuit boards, also known as printed circuit boards, are crucial components in the electronics manufacturing industry. Circuit board conveying devices can automatically complete the transfer of circuit boards on the production line, significantly improving production efficiency. Through precise control and a stable transmission mechanism, circuit boards can be quickly transported from one process stage to another, reducing the time and labor intensity of manual handling and enabling the production line to operate continuously and efficiently.

[0003] In existing circuit board processing and conveying devices, a large number of support rollers are used to lift the conveyor belt. However, in the face of machining deviations and assembly errors, traditional conveyor belts can hardly ensure that the circuit boards they lift are in a plane. During the transmission process, the circuit boards are prone to shaking on the conveyor belt. Circuit boards with soldered electronic components are prone to damage due to poor stability and significant shaking during high-speed transmission. At the same time, the shaking can easily cause the circuit boards to shift during transmission. Utility Model Content

Side plates are provided on the left and right sides of the driven wheel and the drive wheel, and the driven wheel and the drive wheel are rotatably connected between the two side plates.

[0007] Preferably, one of the side plates is provided with a drive motor that can rotate the drive wheel on the side opposite to the drive wheel, and the bottom of the side plate is provided with a downwardly extending support leg.

[0009] Preferably, the bottom of the tray is provided with a guide rod corresponding to the shock-absorbing spring. The guide rod can pass through the inner diameter of the shock-absorbing spring. A damper is also provided between the tray and the plate. The front and rear sides of the tray also include downwardly curved arc plates.

[0010] Preferably, the side of the second board facing the circuit board has a through screw hole, and the side wall of the side plate has a through elongated hole with the length direction of the elongated hole pointing to the upper and lower sides.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a circuit board processing transmission device, including a conveyor belt 121 capable of conveying circuit boards 4. A buffer section is provided at the inner diameter of the conveyor belt 121, and an anti-deviation section is provided at the top of the conveyor belt 121 to reduce the deviation of the circuit board 4. The buffer section includes a shock-absorbing spring 31, and a support plate 33 capable of conforming to the conveyor belt 121 is provided at the top of the shock-absorbing spring 31. The anti-deviation section includes two anti-deviation plates 21 located above the conveyor belt 121, and a drive plate 21 is inserted between the two anti-deviation plates 21. The bidirectional threaded screw 23 moves in opposite directions. The anti-deviation plate 21 includes a front alignment plate 211, which is offset to one side. The alignment plates 211 of the two anti-deviation plates 21 can form an "eight"-shaped opening. The vibration generated by the circuit board 4 being transmitted at high speed on the conveyor belt 121 is absorbed by the shock-absorbing spring 31 of the buffer part. The two anti-deviation plates 21, which can approach each other, can limit the circuit board 4 on the conveyor belt 121 and reduce the deviation of the circuit board 4. The inner diameter of the conveyor belt 121 is provided with a tensioning device for the conveyor belt 121. The driven wheel 111 and drive wheel 112 are arranged in a front-to-back configuration, with the drive wheel 112 located behind the driven wheel 111. Side plates 12 are provided on the left and right sides of the driven wheel 111 and drive wheel 112, respectively. The driven wheel 111 and drive wheel 112 are rotatably connected between the two side plates 12. The driven wheel 111 and drive wheel 112 support the conveyor belt 121, enabling the conveyor belt 121 to carry the circuit board 4. The side plates 12 connect the driven wheel 111 and drive wheel 112. The driven wheel 111 and the drive wheel 112 are positioned. The driven wheel 111 and the drive wheel 112 are connected to the side plate 12 by bearing rotation. One of the side plates 12 is provided with a drive motor that can rotate the drive wheel 112 on the side away from the drive wheel 112. The bottom of the side plate 12 is provided with a downwardly extending support leg 11. The drive wheel 112 is driven to rotate by the drive motor, so that the conveyor belt 121 has the power to transmit. The support leg 11 supports the side plate 12 to prevent the conveyor belt 121 from contacting the ground.

[0021] Please see Figure 2 - Figure 5 In this embodiment, there are two buffer sections. A second buffer section 342 is installed on the side of the side plate 12 near the circuit board 4. A first buffer section 341 is located below the side of the second buffer section 342 near the circuit board 4. The bottom of the first buffer section 341 supports the shock-absorbing spring 31. The two buffer sections support both sides of the conveyor belt 121, increasing the stability of the conveyor belt 121. The first buffer section 341 supports the shock-absorbing spring 31 to prevent it from falling off. The bottom of the support plate 33 is provided with a guide rod 311 corresponding to the shock-absorbing spring 31. The guide rod 311 can pass through the inner diameter of the shock-absorbing spring 31. A damper 32 is also provided between the support plate 33 and the first plate 341. The front and rear sides of the support plate 33 also include downwardly curved arc plates 331. The guide rod 311 limits the shock-absorbing spring 31 to prevent it from shaking or twisting. The damper 32 can tighten the support plate 33 to prevent the shock-absorbing spring 31 from bouncing excessively. The second plate 342 has a through screw hole 35 on the side facing the circuit board 4. The side wall of the side plate 12 has a through elongated hole 120. The length of the elongated hole 120 is square. The screw hole 35 can move up and down within the elongated hole 120, pointing to both the upper and lower sides. The bottom of the side plate 12, corresponding to the position of the elongated hole 120, has a top hole 123 that communicates with the elongated hole 120. By inserting screws through the elongated hole 120 and the screw hole 35, the height of the buffer section can be easily adjusted. Bolts can be inserted into the top hole 123 to limit the screws within the elongated hole 120, reducing the possibility of the buffer section sliding down due to gravity. The tops of the side plates 12 at both ends are respectively provided with fixing plates 24, and a bidirectional threaded screw 2 is rotatably connected between the two fixing plates 24. 3. Guide rods 22 are provided on the front and rear sides of the bidirectional threaded screw 23. The guide rods 22 can pass through the anti-deviation plate 21. A servo motor 231 is installed on the side of one of the anti-deviation plates 21 away from the bidirectional threaded screw 23. The servo motor 231 can drive the bidirectional threaded screw 23 to rotate. The bidirectional threaded screw 23 facilitates the movement of the anti-deviation plates 21 towards or away from each other, which is convenient for correcting the deviation of circuit boards 4 of different widths. The servo motor 231 can precisely control the distance between the two anti-deviation plates 21 to avoid damage to the circuit board 4 caused by pressure.

[0022] During operation, the robotic arm places the circuit board 4 onto the conveyor belt 121 of the circuit board processing conveyor. The drive motor drives the drive wheel 112 to rotate, which in turn drives the conveyor belt 121 and the driven wheel 111 to move together. When the conveyor belt 121 carries the circuit board 4 and moves at high speed, the vibration generated by the conveyor belt 121 is transmitted to the top of the pallet 33 and can be absorbed to a certain extent by the damping spring 31. At the same time, the damper 32 pulls on the bottom of the pallet 33 to prevent the pallet 33 from being damaged by the damping spring 31. The elasticity of the circuit board causes violent bouncing. The circuit board processing and transmission device drives the servo motor 231 to rotate according to the pre-set program, so that the anti-deviation plates 21 on both sides are close to the circuit board 4. Specifically, the distance between the anti-deviation plate 21 and the edge of the width of the circuit board 4 is one millimeter. The anti-deviation plate 21 is not in contact with the conveyor belt 121. When the servo motor 231 drives the bidirectional threaded screw 23 to rotate, the nut seat on the anti-deviation plate 21 drives the anti-deviation plate 21 to move. At the same time, the guide rod 22 limits the two sides of the anti-deviation plate 21 to prevent the anti-deviation plate 21 from rotating.

[0023] Through the above steps, the shock-absorbing spring 31 absorbs the vibration generated by the high-speed transmission of the circuit board 4 on the conveyor belt 121, and the two anti-deviation plates 21 that can approach each other can reduce the deviation of the circuit board 4, so as to solve the problem that the circuit board processing conveyor device in the prior art has poor stability, obvious shaking during high-speed transmission, which leads to damage to the circuit board and causes the circuit board to deviate during transmission.
