[0002] In the current process of interfacing PCBs (Printed Circuit Boards) with processing equipment (e.g., inkjet printers), precise PCB movement is a key factor in ensuring processing quality.

[0003] In existing technologies, lifting devices are typically built into upstream equipment (e.g., flipping machines) to vertically transport PCBs to a conveyor belt, which then transports the PCBs to the processing station of the processing equipment for docking. However, the upstream equipment has a complex structure, and installing lifting devices within it is costly and requires significant maintenance. Utility Model Content

[0004] The technical problem to be solved by this application is that the existing technology of building a lifting device in the upstream equipment to vertically transport the PCB to the conveyor belt and then transporting the PCB to the processing station of the processing equipment to achieve docking with the processing equipment has the problem of high cost. Therefore, this application provides a conveying mechanism and processing equipment.

[0005] To address the aforementioned issues, this application provides a conveying mechanism, including a lifting frame, a mounting beam, a first drive assembly, a conveyor belt, and a second drive assembly. The conveyor belt is disposed on the mounting beam, and the first drive assembly drives the conveyor belt to move, thereby conveying the circuit board along a first direction.

[0006] The upper end of the lifting frame is fixedly connected to the mounting beam, and the second drive assembly is used to drive the lifting frame and the mounting beam to reciprocate in the vertical direction to support the circuit board.

[0007] Optionally, the number of mounting beams and conveyor belts is at least two, with at least two mounting beams arranged at intervals along the second direction on the lifting frame, and each conveyor belt arranged on a corresponding mounting beam. The first drive assembly can drive all the conveyor belts to synchronously transport the circuit board along the first direction; wherein the first direction intersects with the second direction.

[0008] Optionally, the number of the first drive components is at least two, and the output end of each first drive component is connected to a corresponding conveyor belt.

[0009] Optionally, the first drive assembly includes a first drive motor, a drive wheel, and a driven wheel. The drive wheel and the driven wheel are spaced apart on the mounting beam along the first direction. The conveyor belt surrounds the outer peripheral surface of the drive wheel and the outer peripheral surface of the driven wheel. The drive wheel is fixedly connected to the output end of the first drive motor. The first drive motor drives the drive wheel and then drives the conveyor belt to transport the circuit board along the first direction.

[0010] Optionally, the first drive assembly further includes a transfer component, a connecting plate is provided on the side of the mounting beam near the lifting frame, the first drive motor is arranged on the connecting plate, the transfer component is connected between the drive wheel and the output end of the first drive motor, and the first drive motor drives the drive wheel to rotate through the transfer component.

[0011] Optionally, the transfer component includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a rotating shaft. The rotating shaft is rotatably connected to the mounting beam about a first axis and extends along a second direction. The extension direction of the first axis is parallel to the second direction.

[0012] The driving wheel and the first synchronous wheel are fixedly connected to the rotating shaft at intervals along the second direction. The second synchronous wheel is fixedly connected to the output end of the first drive motor. The synchronous belt wraps around the outer circumferential surface of the first synchronous wheel and the outer circumferential surface of the second synchronous wheel. The first direction intersects the second direction.

[0013] Optionally, the conveying mechanism further includes a guide rail, which is arranged on one side of the lifting frame and extends vertically.

[0016] According to the conveying mechanism of this application embodiment, when the conveyor belt needs to receive a circuit board (PCB), the second drive component drives the lifting frame to move upward. Since the lifting frame is fixedly connected to the mounting beam, the mounting beam, along with the conveyor belt mounted on it, also rises. During the rising process, the conveyor belt gradually approaches and connects with the PCB conveyed from the upstream equipment, smoothly receiving the PCB on the conveyor belt. After receiving, the first drive component starts, driving the conveyor belt to move along a first direction (usually horizontal), conveying the PCB received on the conveyor belt forward until the PCB is conveyed to the next working state position, completing the entire conveying process. By integrating the lifting function and the conveyor belt conveying function into one unit, the lifting device in the upstream equipment (folding machine) is successfully eliminated, simplifying the structure of the upstream equipment and significantly reducing manufacturing and maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] like Figures 1 to 3 As shown, one embodiment of this application provides a conveying mechanism, including a lifting frame 1, a mounting beam 2, a first drive assembly 3, a conveyor belt 4, and a second drive assembly 5. The conveyor belt 4 is disposed on the mounting beam 2, and the first drive assembly 3 is used to drive the conveyor belt 4 to move so as to convey the circuit board along a first direction.

[0028] The upper end of the lifting frame 1 is fixedly connected to the mounting beam 2. The second drive assembly 5 is used to drive the lifting frame 1 and the mounting beam 2 to reciprocate vertically to support the circuit board. In this embodiment, the lifting height of the lifting frame 1 and the mounting beam 2 is precisely controlled by the second drive assembly 5, ensuring accurate transmission of the PCB from the upstream equipment (turnover machine) to the processing equipment (inkjet printer). By integrating the lifting function and the conveyor belt 4 into one unit, the need for a separate lifting device in the upstream equipment is avoided, the number of internal components in the upstream equipment is reduced, the overall structure is simplified, and thus the equipment cost is significantly reduced.

[0029] In one embodiment, there are at least two mounting beams 2 and at least two conveyor belts 4. The at least two mounting beams 2 are arranged at intervals along a second direction on the lifting frame 1. Each conveyor belt 4 is arranged on a corresponding mounting beam 2. The first drive assembly 3 can drive all the conveyor belts 4 to synchronously convey the circuit board along the first direction; wherein the first direction intersects the second direction. In this embodiment, the first direction is the auxiliary direction. Figure 2 In the X direction, the first direction is the attached Figure 2 In the Y direction. The circuit board is placed on multiple conveyor belts 4, which coordinate to transport the circuit board. The design of multiple conveyor belts 4 can distribute the weight and pressure of the circuit board, reduce the load on a single conveyor belt 4, thereby improving the stability and reliability of the transport. For larger or heavier circuit boards, it can effectively prevent the conveyor belts 4 from malfunctioning or being damaged due to excessive load.

[0030] In one embodiment, the number of first drive components 3 is at least two, and the output end of each first drive component 3 is connected to a corresponding conveyor belt 4. In this embodiment, one drive component independently drives one conveyor belt 4. Even if one drive component fails, the other drive components can still continue to work, thereby reducing the risk of the entire system being paralyzed due to a single point of failure and enhancing the reliability and stability of the system.

[0031] Please see Figure 2 In one embodiment, the first drive assembly 3 includes a first drive motor 31, a drive wheel 32, and a driven wheel 33. The drive wheel 32 and the driven wheel 33 are spaced apart along a first direction on the mounting beam 2. The conveyor belt 4 surrounds the outer circumferential surfaces of the drive wheel 32 and the driven wheel 33. The drive wheel 32 is fixedly connected to the output end of the first drive motor 31. The first drive motor 31 drives the conveyor belt 4 to transport the circuit board along the first direction by driving the drive wheel 32. In this embodiment, the first drive motor 31 directly drives the conveyor belt 4 through the drive wheel 32, resulting in a short power transmission path, high efficiency, and ensuring that the conveyor belt 4 transports the circuit board along the first direction at a stable speed.

[0032] Please see Figure 2 In one embodiment, the first drive assembly 3 further includes a transfer component 34. A connecting plate 7 is provided on the side of the mounting beam 2 near the lifting frame 1. The first drive motor 31 is arranged on the connecting plate 7. The transfer component 34 connects the drive wheel 32 and the output end of the first drive motor 31. The first drive motor 31 drives the drive wheel 32 to rotate through the transfer component 34. In this embodiment, by setting the first drive motor 31 on the connecting plate 7 and driving the drive wheel 32 to rotate through the transfer component 34, the first drive motor 31 can avoid collisions with the PCB during PCB transportation, ensuring the safe and stable operation of the production process.

[0033] Please see Figure 2 In one embodiment, the transfer component 34 includes a first synchronous pulley 341, a second synchronous pulley 342, a synchronous belt 343, and a rotating shaft 344. The rotating shaft 344 is rotatably connected to the mounting beam 2 about a first axis and extends along a second direction. The extension direction of the first axis is parallel to the second direction.

[0034] The drive pulley 32 and the first synchronous pulley 341 are fixedly connected to the rotating shaft 344 at intervals along the second direction. The second synchronous pulley 342 is fixedly connected to the output end of the first drive motor 31. The synchronous belt 343 surrounds the outer circumferential surfaces of the first synchronous pulley 341 and the second synchronous pulley 342. The first direction intersects the second direction. In this embodiment, the combination of the first synchronous pulley 341, the second synchronous pulley 342, and the synchronous belt 343 realizes the power transmission between the first drive motor 31 and the drive pulley 32, ensuring that the drive pulley 32 rotates at a precise speed and rhythm, thereby enabling the conveyor belt 4 to stably transport the circuit board and ensuring the positional accuracy and speed consistency of the circuit board during the transport process.

[0035] In one embodiment, the conveying mechanism further includes a guide rail 6, which is arranged on one side of the lifting frame 1 and extends vertically. The lifting frame 1 is slidably connected to the guide rail 6. The second drive assembly 5 can drive the lifting frame 1 to reciprocate along the guide rail 6 to receive the circuit board. In this embodiment, when the second drive assembly 5 drives the lifting frame 1 to reciprocate, the guide rail 6 can effectively restrict the movement trajectory of the lifting frame 1, making it move only in the vertical direction. This reduces swaying and offset during the lifting process, thereby ensuring the positional accuracy of the mounting beam 2, conveyor belt 4, and circuit board installed on the lifting frame 1 during the lifting process, which helps to accurately receive the PCB conveyed by the upstream equipment.

[0036] Please see Figure 3 In one embodiment, the second drive assembly 5 includes a second drive motor 51, a lead screw 52, ​​and a mounting base 53. The lead screw 52 is fixedly connected to the output end of the second drive motor 51 and extends vertically. The mounting base 53 is arranged on the lifting frame 1. The lead screw 52 has an external thread, and the inner hole of the mounting base 53 has an internal thread. The lead screw 52 is threadedly connected to the inner hole of the mounting base 53. In this embodiment, the second drive motor 51 drives the lead screw 52 to rotate, and the rotation of the lead screw 52 is converted into the linear lifting motion of the lifting frame 1. This ensures the vertical movement accuracy of the lifting frame 1, thereby improving the positioning accuracy of the entire conveying mechanism. Simultaneously, the threaded connection has good self-locking performance, which can maintain the stability of the lifting frame 1 during lifting and preventing positional deviation of the lifting frame 1 due to external forces or vibrations, ensuring the smoothness and reliability of the lifting process.

[0037] In one embodiment, there are two guide rails 6, spaced apart along a second direction, with a lead screw 52 positioned between them; the first and second directions intersect. In this embodiment, the two guide rails 6 spaced apart along the second direction provide more stable support for the lifting frame 1. Compared to a single guide rail 6, the double guide rails 6 better distribute the weight and movement forces of the lifting frame 1, reducing swaying and offset, and improving the stability of the lifting process. The lead screw 52 positioned between the two guide rails effectively prevents the lifting frame 1 from twisting during lifting. The symmetrical arrangement of the guide rails 6 and the central position of the lead screw 52 ensure smoother vertical movement of the lifting frame 1, avoiding decreased accuracy and equipment damage caused by twisting.

[0038] According to the conveying mechanism of this application embodiment, when the conveyor belt 4 needs to receive a circuit board (PCB), the second drive assembly 5 drives the lifting frame 1 to move upward. Since the lifting frame 1 is fixedly connected to the mounting beam 2, the mounting beam 2, along with the conveyor belt 4 mounted on it, also rises. During the rising process, the conveyor belt 4 gradually approaches and connects with the PCB conveyed from the upstream equipment, smoothly receiving the PCB on the conveyor belt 4. After receiving, the first drive assembly 3 starts, driving the conveyor belt 4 to move along a first direction (usually horizontal), conveying the PCB received on the conveyor belt 4 forward until the PCB is conveyed to the next working state position, completing the entire conveying process. By integrating the lifting function and the conveyor belt 4 conveying function into one unit, the lifting device in the upstream equipment (folding machine) is successfully eliminated, simplifying the structure of the upstream equipment and significantly reducing manufacturing and maintenance costs.

[0039] In addition, one embodiment of this application provides a processing device, including the conveying mechanism described in the above embodiment.

[0040] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
