Description

Technical Field

[0001] This utility model mainly relates to the field of PCB board conveying technology, specifically a conveying assembly line for PCB board processing workshops. Background Technology

[0002] A PCB, or Printed Circuit Board, is a board used for the mechanical support and electrical connection of electronic components. It achieves electrical connections between electronic components by printing conductive patterns (usually copper foil) onto an insulating substrate. PCBs are an indispensable component of modern electronic devices and are widely used in computers, communication equipment, consumer electronics, industrial control, and other fields.

[0003] Traditional conveyor lines lack automatic flipping mechanisms. When double-sided processing or inspection of PCBs is required, workers have to frequently flip the PCBs manually. This manual operation not only greatly increases the workload but also significantly reduces production efficiency and makes it impossible to flexibly adjust the equipment according to the specific size of the PCBs, which greatly limits the applicability of the equipment. Utility Model Content

[0004] This utility model mainly provides a conveyor line for PCB board processing workshops to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A conveyor line for a PCB manufacturing workshop includes a base plate and a first placement plate. A mounting plate is fixedly connected to one side of the top of the base plate, and an adjustment mechanism is provided on one side of the mounting plate. A limiting mechanism is provided on the side of the mounting plate away from the adjustment mechanism. A connecting plate is fixedly connected to the top of the base plate on the side away from the mounting plate, and a second placement plate is fixedly installed on the top of the connecting plate.

[0007] Both the first and second placement plates are provided with conveyor belts on one side, and both the first and second placement plates are provided with a flipping mechanism between the two conveyor belts on one side.

[0008] Preferably, the adjustment mechanism includes a first motor, a threaded rod, and an adjustment block. The first motor is fixedly installed on one side of the mounting plate, and the output shaft of the first motor is connected to the threaded rod through the mounting plate via a rotating shaft. One end of the threaded rod is fixedly connected to the connecting plate via a rotating shaft, and the outer side of one end of the threaded rod is threadedly connected to the adjustment block. The top of the adjustment block is fixedly connected to one side of the bottom of the first placement plate.

[0009] Preferably, the limiting mechanism includes a limiting rod and a limiting block. The mounting plate is fixedly connected to the limiting rod on the side away from the adjusting mechanism, and one end of the limiting rod is fixedly connected to the connecting plate. The outer side of one end of the limiting rod is movably connected to the limiting block through a mounting hole, and the top of the limiting rod is fixedly connected to the other side of the bottom of the first placement plate.

[0010] Preferably, the threaded connection between the threaded rod and the adjusting block has rolling balls for rolling friction.

[0011] Preferably, the number of conveyor belts is four, with two on one side of the first placement plate and two on one side of the second placement plate.

[0012] Preferably, the flipping mechanism includes a second motor, a flipping plate, a mounting bracket, an electric push rod, and a pressing block. The second motor is fixedly connected to one side of both the first and second placement plates, and the output shaft of the second motor passes through the first and second placement plates via a rotating shaft to form the flipping plate. The mounting bracket is fixedly connected to both sides of the top of the flipping plate, and an electric push rod is fixedly connected to both sides of the inner top wall of the mounting bracket. At the same time, a pressing block is fixedly connected to the bottom of the electric push rod.

[0013] Preferably, the pressing block is made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The flipping mechanism enables efficient PCB board flipping. The conveyor belt precisely transports the PCB board to the area below the pressing block inside the mounting frame. The electric push rod is activated, driving the pressing block to descend until it makes close contact with the edge of the PCB board. Since the pressing block is made of rubber, scratches or other damage to the PCB board surface are avoided. Then, the second motor is activated, and its output shaft drives the flipping plate to rotate precisely, completing the PCB board flipping operation. After flipping, the electric push rod is activated again, driving the pressing block to rise, thereby releasing the PCB board. The conveyor belt on the other side then transports the flipped PCB board to the next process. The entire flipping process is not only efficient and smooth, but also provides comprehensive protection for the PCB board, effectively improving production efficiency and product quality.

[0016] The adjustable mechanism allows for flexible adjustment to accommodate PCBs of different sizes. When adjusting the distance between the first and second placement plates, simply start the first motor. Its output shaft will drive the threaded rod to rotate, which in turn moves the adjusting block along the thread direction. This allows the first placement plate to move closer to or further away from the second placement plate, flexibly handling PCBs of different sizes. This greatly improves the equipment's versatility and adaptability, meeting diverse production needs. The ball bearings at the threaded connection between the threaded rod and the adjusting block use rolling friction instead of traditional sliding friction, effectively reducing wear between mechanical parts, lowering the risk of equipment failure due to long-term operation, improving transmission efficiency, and thus extending the service life of the device.

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0024] Please refer to the appendix carefully. Figure 1-4A conveyor line for a PCB manufacturing workshop includes a base plate 1 and a first placement plate 2. A mounting plate 3 is fixedly connected to one side of the top of the base plate 1, and an adjustment mechanism 4 is provided on one side of the mounting plate 3 for adjusting the distance between the first placement plate 2 and a second placement plate 7 to accommodate PCBs of different sizes. The adjustment mechanism 4 includes a first motor 401, a threaded rod 402, and an adjustment block 403. The first motor 401 is fixedly mounted on one side of the mounting plate 3, and its output shaft passes through the mounting plate 3 via a rotating shaft to connect to the threaded rod 402. One end of the threaded rod 402 is fixedly connected to a connecting plate 6 via the rotating shaft. The outer side of the threaded rod 402 is threadedly connected to the adjustment block 403. The top of the adjustment block 403 is connected to... The bottom side of the first placement plate 2 is fixedly connected. Driven by the first motor 401, the threaded rod 402 rotates, thereby driving the adjusting block 403 to move along the thread direction, realizing the position adjustment of the first placement plate 2. The threaded connection between the threaded rod 402 and the adjusting block 403 has rolling friction balls 10. Rolling friction replaces sliding friction, which can reduce mechanical damage and increase its service life. In addition, the mounting plate 3 is provided with a limiting mechanism 5 on the side away from the adjusting mechanism 4. The limiting mechanism 5 includes a limiting rod 501 and a limiting block 502. The limiting rod 501 is fixedly connected to the mounting plate 3 on the side away from the adjusting mechanism 4. One end of the limiting rod 501 is fixedly connected to the connecting plate 6. The outer side of the limiting rod 501 is open to the connecting plate 6. A limiting block 502 is movably connected through the mounting hole. The top of the limiting block 502 is fixedly connected to the other side of the bottom of the first placement plate 2 to prevent the first placement plate 2 from shifting or shaking during adjustment, ensuring the stability and reliability of the device. A connecting plate 6 is fixedly connected to the top of the base plate 1 on the side away from the mounting plate 3, and a second placement plate 7 is fixedly installed on the top of the connecting plate 6. A conveyor belt 8 is provided on one side of both the first placement plate 2 and the second placement plate 7. There are four conveyor belts 8 in total, with two on one side of the first placement plate 2 and two on one side of the second placement plate 7. A flipping mechanism 9 is provided between the two conveyor belts on both sides of the first placement plate 2 and the second placement plate 7. The flipping mechanism 9 includes a first... The system comprises two motors 901, a flip plate 902, a mounting bracket 903, an electric push rod 904, and a pressing block 905. A second motor 901 is fixedly connected to one side of both the first placement plate 2 and the second placement plate 7. The output shaft of the motor 901 passes through the first placement plate 2 and the second placement plate 7 via a rotating shaft to form a flip plate 902. Mounting brackets 903 are fixedly connected to both sides of the top of the flip plate 902. Electric push rods 904 are fixedly connected to both sides of the inner top wall of the mounting brackets 903. A pressing block 905 is fixedly connected to the bottom of the electric push rods 904. The pressing block 905 is made of rubber, which has good elasticity and wear resistance, providing appropriate cushioning when pressing the PCB board and protecting it from damage.

[0025] The specific operation method of this utility model is as follows:

[0026] In use, the conveyor belt 8 transports the PCB board to the inside of the mounting frame 903 under the pressing block 905. The electric push rod 904 is activated to descend, which in turn drives the pressing block 905 to descend until the pressing block 905 contacts the edge of the PCB board. Since the pressing block 905 is made of rubber, it will not scratch the PCB board. Then, the second motor 901 is activated so that its output shaft drives the flipping plate 902 to rotate 180 degrees. After the flipping is completed, the electric push rod 904 drives the pressing block 905 to move upward, thereby releasing the PCB board. Then, the other side of the conveyor belt 8 transports the PCB board to the next process.

[0027] When the required spacing between the first placement plate 2 and the second placement plate 7 is needed, the first motor 401 is started, causing its output shaft to drive the threaded rod 402 to rotate, which in turn drives the adjusting block 403 to move. This causes the first placement plate 2 to move closer to or further away from the second placement plate 7, thereby adjusting the width between the first placement plate 2 and the second placement plate 7. This method is suitable for PCB boards of different sizes. The ball bearings 10 at the threaded connection between the threaded rod 402 and the adjusting block 403 use rolling friction instead of sliding friction, which can significantly reduce mechanical wear, improve transmission efficiency, and increase the service life of the device.

[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
