The board 4 to be conveyed can be a PCB board, and its thickness and vertical placement height can be determined according to actual production needs.

[0022] Optionally, the conveying device may include a frame, which may be made of high-strength steel welded together or aluminum profile assembled together, having sufficient rigidity and stability. The frame may be placed on the floor of the production workshop, and the lifting unit 3 may be fixed to the frame.

[0023] The upper conveyor module 2 and the lower conveyor module 1 can be fixed on the frame, and the upper conveyor module 2 and the lower conveyor module 1 are arranged at intervals. The plate to be transported 4 passes between the upper conveyor module 2 and the lower conveyor module 1 in a vertical manner. When the plate is transported by the conveyor belt, the upper conveyor module 2 and the lower conveyor module 1 contact the plate to be transported 4 and form a structure that restricts the plate to be transported 4 from tilting through their own structure (such as having a groove or clamping the plate to be transported 4 on the side that contacts the plate to be transported 4).

[0024] Optionally, the lower conveying module 1 includes a lower conveying component, and the upper conveying module 2 includes an upper conveying component 21. The lower conveying module 1 and the upper conveying component 21 are opposite to and in contact with the plate to be conveyed 4 to fix and convey the plate to be conveyed 4. The lifting unit 3 is fixed to the side of the lower conveying component and / or the upper conveying component 21 away from the plate to be conveyed 4.

[0025] In one embodiment, the lifting unit 3 can be fixed on the lower conveying component, and during transmission, the distance between the lower conveying component and the upper conveying component 21 can be adjusted according to the height of the plate 4 to be transmitted, thereby adapting to plate 4 of different heights.

[0026] Optionally, the lifting unit 3 includes a lifting bracket 32 ​​and a lifting drive assembly 31. One end of the lifting bracket 32 ​​is fixed to the lower conveying assembly and / or the upper conveying assembly 21, and the lifting drive assembly 31 is connected to the other end of the lifting bracket 32 ​​to drive the lifting bracket 32 ​​to lift.

[0027] Optionally, the lifting drive assembly 31 can be fixed to the frame, and the lifting drive assembly 31 can drive the lower conveying assembly and / or the upper conveying assembly 21 to move up and down along the height direction of the plate to be conveyed 4. The lifting drive assembly 31 can drive the lifting bracket 32 ​​to move up and down via cylinders, motors, and other power mechanisms. Each lifting bracket 32 ​​can be connected to one lifting drive assembly 31, or a single lifting drive assembly 31 can be connected to two or more lifting brackets 32.

[0028] Optionally, when the lower conveying component and / or the upper conveying component 21 is a strip structure, the number of lifting brackets 32 can be two or more, which can be fixed at both ends or multiple positions of the strip structure to ensure that the lower conveying component and / or the upper conveying component 21 rises and falls smoothly.

[0029] In one embodiment, the lifting unit 3 can be fixed on the lower conveying assembly, and the number of lifting brackets 32 can be two. The lower conveying assembly is a strip structure, and the lifting brackets 32 are fixedly connected to both ends of the strip structure. The lifting drive assembly 31 drives the lifting brackets 32 at both ends of the lower conveying assembly to rise and fall synchronously.

[0030] Optionally, the lifting drive assembly 31 includes a lifting driver 315, a transmission rod 311, and a screw 313. The lifting driver 315 is drive-connected to the transmission rod 311, and the transmission rod 311 is provided with a worm gear. The screw 313 is threadedly connected to the lifting bracket 32, and a worm wheel 312 is fixed to one end of the screw 313. The worm wheel 312 is drive-connected to the worm gear. The lifting driver 315 can be a motor, and the lifting height of the lifting bracket 32 ​​is controlled by controlling the speed of the motor.

[0031] In one embodiment, a fixing plate 316 may be provided on one side of the lifting driver 315, and the lifting driver 315 is fixed on the fixing plate 316. A driven wheel 317 and a pulse disk 318 may be provided on the transmission rod 311. The driving end of the lifting driver 315 is connected to the driven wheel 317 (e.g., via a toothed belt) and drives the driven wheel 317 to rotate, thereby driving the transmission rod 311 to rotate. The edge of the pulse disk 318 has multiple spaced grooves. The fixing plate 316 is opposite to the pulse disk 318, and the fixing plate 316 is provided with a pulse sensor 310 corresponding to each groove. The pulse sensor 310 can emit a pulse signal when it detects a groove on the pulse disk 318, and then detect the rotational speed of the transmission rod 311 through the pulse signal. Specifically, the pulse sensor 310 can be a photoelectric sensor.

[0032] Optionally, the horizontal rotation of the transmission rod 311 is converted into the vertical rotation of the screw 313 by the worm and worm wheel 312, and the rotation of the screw 313 drives the lifting bracket 32 ​​to rise and fall. To protect the worm and worm wheel 312, the lifting drive assembly 31 may also include a protective housing 314, with the worm and worm wheel 312 housed within the protective housing 314, and the screw 313 and transmission rod 311 inserted into the protective housing 314.

[0033] Optionally, the upper part of the lifting bracket 32 ​​may be provided with a mounting base 324. The mounting base 324 is provided with a screw hole corresponding to the screw 313. The screw 313 is threadedly connected to the screw hole. When the screw 313 rotates, the mounting base 324 rises and falls accordingly, thereby driving the lifting bracket 32 ​​to rise and fall.

[0034] Optionally, the lifting bracket 32 ​​may include a guide column 321, a top seat 323, and a base 326. The base 326 is fixed on the upper conveying assembly 21 or the lower conveying assembly. The bottom of the guide column 321 is fixed on the base 326, and the top is fixedly connected to the top seat 323. One side of the mounting base 324 is fixed to the side of the top seat 323.

[0035] In one embodiment, to ensure that the lifting bracket 32 ​​moves up and down in a fixed direction, the lifting bracket 32 ​​may further include a bushing 322, which can be fixed to the frame of the conveying device. There may be two guide posts 321, with the bushing 322 fitted onto each guide post 321, thus restricting the guide post 321 from moving up and down in a fixed direction. To prevent dust and oil from entering and affecting lifespan and accuracy, a rubber ring is provided at the end of the bushing 322 for sealing. The rubber ring is compressed between the bushing 322 and the guide post 321, effectively isolating external contaminants while allowing the guide rod to slide smoothly, ensuring the long-term reliability of the lifting unit 3.

[0036] Optionally, the conveying device also includes a detection component 5, which is located on one side of the lifting bracket 32 ​​and is used to detect the lifting height of the lifting bracket 32 ​​and trigger an alarm. The detection component 5 can detect whether the lifting bracket 32 ​​has returned to its origin or whether its travel has exceeded limits (such as crossing the origin or the descent height exceeding a predetermined threshold). The conveying device can issue an audible and visual alarm or indicate that it is currently operating normally based on the detection results of the detection component 5, allowing operators to promptly understand the device's operating status and avoid transmission failures caused by improper adjustments.

[0037] Optionally, the mounting base 324 is connected to the lifting drive assembly 31 via a transmission connection. The mounting base 324 is provided with a limiting plate 325 on the side near the detection assembly 5. The detection assembly 5 includes a detection plate 51, a first detection sensor 52, and a second detection sensor 53. The first detection sensor 52 and the second detection sensor 53 are located on the side of the detection plate 51 near the limiting plate 325, and the setting heights of the first detection sensor 52 and the second detection sensor 53 are different. The first detection sensor 52 and the second detection sensor 53 are used to issue trigger signals when the limiting plate 325 passes by or leaves, thereby determining the current lifting height of the lifting bracket 32. When the limiting plate 325 triggers the first detection sensor 52, it means that the lifting bracket 32 ​​has returned to the initial origin position. When the limiting plate 325 triggers the second detection sensor 53, it means that the descent height of the lifting bracket 32 ​​has reached the preset maximum threshold. At this time, the device will stop driving the lifting bracket 32 ​​to continue to descend and issue a warning signal to remind the operator to avoid structural collision failure caused by exceeding the travel limit.

[0038] Optionally, the detection plate 51 can be fixed to the frame. The first detection sensor 52 and the second detection sensor 53 can be photoelectric sensors, Hall sensors, or other sensors that can emit a trigger signal when the limit plate 325 approaches. A two-stage protection function can be set up using the first detection sensor 52 and the second detection sensor 53. The first stage of the first detection sensor 52 is position detection, serving as origin correction; the second stage is a light alarm (e.g., when the limit plate 325 rises and crosses the origin). The second stage of the lower photoelectric sensor is an alarm protection to prevent damage to the plate (e.g., when the second detection sensor 53 detects the limit plate 325 and triggers an alarm).

[0039] Optionally, the detection component 5 can be installed only on the entry side of the plate 4 to be transferred in the conveying device, so as to detect whether the lifting stroke of the lifting unit 3 meets the requirements before the plate 4 to be transferred is transferred.

[0040] Optionally, the upper conveying assembly 21 includes an upper conveying frame 212, a connecting rod 213, an elastic element 211, and a conveying wheel 214. The connecting rod 213 and the conveying wheel 214 are located on both sides of the board to be conveyed 4. The connecting rod 213 and the conveying wheel 214 on the same side of the board to be conveyed 4 are rotatably connected. The connecting rod 213 is fixed to the side of the upper conveying frame 212 near the board to be conveyed 4. The bottom of the conveying wheel 214 contacts the board to be conveyed 4, and the top extends through the movable groove of the upper conveying frame 212 to the side of the upper conveying frame 212 away from the connecting rod 213 and is connected to one end of the elastic element 211. The length of the movable groove corresponds to the range of motion of the top. The conveying wheels 214 connected to both ends of the elastic element 211 are located on different sides of the board to be conveyed 4. When PCBs of different thicknesses pass by, the elastic deformation of the elastic element 211 automatically adapts to the boards of different thicknesses, while maintaining a flexible clamping force on the board. This avoids rigid clamping that could damage the PCB and ensures the stability of the clamping, preventing the board from shifting or shaking during the conveying process. Specifically, the elastic element 211 can be a tension spring, which has a simple and reliable structure, is easy to install and maintain, and has a low cost.

[0041] Optionally, the connecting rods 213 and conveyor wheels 214 on the upper conveyor frame 212 can be symmetrically arranged. During transmission, the connecting rods 213 and conveyor wheels 214 clamp the board 4 to be transmitted, preventing the board 4 from tipping over. The diameter of the lower part of the conveyor wheel 214 can be larger than the diameter of the connecting rod 213, and the surface of the wheel can be knurled for anti-slip treatment to increase the friction between it and the PCB board, further improving transmission stability and preventing slippage or deviation.

[0042] Optionally, the lower conveying assembly includes a drive shaft 13, a lower magnetic wheel, an upper magnetic wheel 12, and a guide wheel 11. The upper magnetic wheel 12 and the guide wheel 11 are connected one-to-one. The guide wheel 11 is arranged along the movement direction of the board 4 to be conveyed to transport the board 4. The lower magnetic wheel is located below the upper magnetic wheel 12 and fixed on the drive shaft 13. The drive shaft 13 is used to drive the lower magnetic wheel to rotate, thereby driving the upper magnetic wheel 12 and the guide wheel 11 to rotate, and thus driving the PCB board located between the upper conveying module 2 and the lower conveying module 1 to move in a preset direction. Each lower magnetic wheel can correspond to one upper magnetic wheel 12. The use of magnetic wheels for non-contact transmission eliminates the need for direct gear meshing, reducing wear caused by transmission meshing, lowering operating noise, and preventing contaminants such as lubricating oil from falling onto the PCB board and causing contamination, thus ensuring the cleanliness of PCB production and processing. The surface of the guide wheel 11 may have a flexible anti-slip layer, which may be a polyurethane rubber sleeve. This layer can buffer rigid contact while ensuring friction, thus preventing scratches on the edges of the PCB board.

[0043] Alternatively, the magnetic wheel may not be provided in the lower conveying assembly. Instead, a gear or other transmission mechanism connected to the guide wheel 11 may be provided to drive the guide wheel 11 to rotate.

[0044] Optionally, the lower conveyor assembly may also include a translation driver, on which a gear 15 can be driven. The translation driver is connected to the gear 15, and drives the lower magnetic wheel to rotate via the gear 15. Specifically, the translation driver may be a motor, which can be connected to the gear 15 via a chain.

[0045] Optionally, the lower conveying assembly may include a mounting bracket 14 with a mounting plate 141, a guide wheel 11 and an upper magnetic wheel 12 mounted on the mounting plate 141 bracket, and the guide wheel 11 and the upper magnetic wheel 12 rotatably fixed on the mounting plate 141.

[0046] In one embodiment, the guide wheel 11 has an annular groove corresponding to the plate 4 on the side that contacts the plate 4 to be transferred. The lower part of the plate 4 to be transferred is located in the annular groove, which plays an auxiliary limiting role in the vertical state of the plate 4 to be transferred, preventing the plate from tilting to the side during the transfer process and further improving the transfer stability.

[0047] The PCB conveying device provided in this application includes: a lower conveying module 1, used to contact the bottom of the board 4 to be conveyed and to convey the board 4; an upper conveying module 2, located above the lower conveying module 1, used to contact the top of the board 4 to cooperate with the lower conveying module 1 to movably fix the board 4; the lower conveying module 1 and / or the upper conveying module 2 are provided with a lifting unit 3, which is used to adjust the distance between the lower conveying module 1 and the upper conveying module 2 to adapt to boards 4 of different heights. This embodiment of the application can adjust the distance between the lower conveying module 1 and the upper conveying module 2 through the lifting unit 3, without replacing the conveying device or manually disassembling and modifying the structure, thus adapting to PCBs of different heights and specifications and enabling stable transmission. This reduces the equipment cost investment brought by multi-specification customized conveying devices and saves the time spent on manual structural adjustments, effectively improving the overall efficiency of PCB production and processing. At the same time, it can accurately adjust the clamping distance according to the actual height of the PCB to be conveyed, avoiding transmission jams, offsets, or even slippage caused by improper manual adjustment, ensuring the stability of the PCB transmission process, and thereby improving the yield of PCB processing.

[0048] According to one aspect of the embodiments of this application, a PCB production equipment is provided. The equipment may include a PCB conveying device as described in the above embodiments. The equipment may use the PCB conveying device to transfer a PCB board to a processing position or to remove a processed PCB board from the processing position.
