Description

Technical Field

[0001] This utility model relates to the field of production and processing technology, specifically a novel conveyor track structure. Background Technology

[0002] PCB printing machines are used to print circuits on printed circuit boards (PCBs). During printing, the PCB is fixed on the machine's work platform, and the printing device prints the circuit. Currently, in existing PCB printing machine platforms, after one PCB is printed, the next PCB cannot enter until the previous one has been conveyed out, resulting in long waiting times and reduced production efficiency. Since different types of PCBs have different thicknesses, printing on PCBs of varying thicknesses requires maintaining an optimal printing height. However, most current PCB printing machines still require manual adjustments to the work platform height when processing PCBs of different thicknesses, which is time-consuming, labor-intensive, and inefficient. Therefore, providing a novel conveyor track structure is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] The purpose of this invention is to provide a novel conveyor track structure to solve the aforementioned technical problems. This invention, through a dual conveyor belt design, enables a waiting-for-board function. As the printed PCB board is conveyed out, the next PCB board can simultaneously enter, eliminating the need to wait for the previous board to exit before it re-enters, thus reducing waiting time and improving production efficiency. Simultaneously, a lifting and adjusting component is included to achieve automatic height adjustment, catering to the printing needs of various PCB boards. It is flexible, convenient, and highly practical.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A novel conveyor track structure includes a support platform, with Y-axis sliding components on both sides of the support platform along the Y-axis direction, and track bases on both sides of the support platform along the X-axis direction. A conveyor track is provided above the track bases, and a first conveyor component, a second conveyor component, and a lifting adjustment component are installed on the conveyor track. The first conveyor component is located on one side of the second conveyor component along the X-axis direction, and the upper end of the lifting adjustment component is connected to the conveyor track. The lifting adjustment component can drive the conveyor track to move up and down along the Z-axis direction.

[0006] Furthermore, the first conveying component includes a first driving member and a first conveying synchronous wheel. The first driving member is fixed on the side of the conveying track away from the support platform, and the output end of the first driving member passes through the support platform and is connected to the first conveying synchronous wheel.

[0007] Furthermore, the first conveying assembly also includes a first conveyor belt, a plurality of first conveying synchronous pulleys, a plurality of first synchronous pulleys, and a plurality of first supporting synchronous pulleys. The first conveyor belt, the first conveying synchronous pulleys, the first synchronous pulleys, and the first supporting synchronous pulleys are all installed on the side of the conveying track close to the support platform, and the first conveyor belt is wound around the first conveying synchronous pulleys, the first synchronous pulleys, and the first supporting synchronous pulleys.

[0008] Furthermore, the lifting adjustment assembly includes a lifting drive component, a lifting timing belt, a lifting transmission wheel, and several lifting timing wheels. The lifting drive component is fixed on the lower track base. The output end of the lifting drive component passes through the track base and is connected to the lifting transmission wheel. The lifting timing wheels are located on both sides of the lifting transmission wheel. The lifting timing belt is wound around the lifting transmission wheel and the lifting timing wheels.

[0009] Furthermore, the lifting adjustment assembly also includes a lead screw shaft, a lead screw nut, and a bearing. The lead screw nut is threadedly and movably sleeved on the lead screw shaft. The upper end of the lead screw nut is connected to the transmission track. The bearing is located between the lead screw nut and the lifting synchronous wheel. The lower end of the lead screw shaft is connected to the lifting synchronous wheel. The rotation of the lifting synchronous wheel drives the lead screw shaft to rotate.

[0010] Furthermore, the lifting adjustment assembly also includes a guide rail, a slider, and a guide connecting block. The guide rail is fixedly installed on the track base, the slider is slidably connected to the guide rail, one side of the slider is connected to the guide connecting block, and the upper end of the guide connecting block is connected to the conveying track. When the slider slides up and down along the guide rail, it can drive the conveying track to move up and down.

[0011] Furthermore, the Y-axis sliding assembly includes a Y-axis slide rail and a Y-axis sliding block. The Y-axis slide rail is symmetrically mounted on the support platform, and the Y-axis sliding block is slidably connected to the Y-axis slide rail. The upper end of the Y-axis sliding block is connected to the track base.

[0012] Furthermore, the Y-axis sliding assembly also includes a Y-axis lead screw and a slide rod connecting seat. The Y-axis lead screw is installed at the lower end of the support platform, and a nut bracket is threaded onto the Y-axis lead screw. One side of the nut bracket is connected to the slide rod connecting seat, and the upper end of the slide rod connecting seat is connected to the track base.

[0013] Furthermore, the Y-axis sliding assembly also includes a Y-axis sliding drive, a Y-axis synchronous belt, a Y-axis transmission wheel, several Y-axis synchronous wheels, and several Y-axis rotating wheels.

The Y-axis rotating wheel is sleeved on one end of the Y-axis lead screw, and the Y-axis synchronous belt is wound around the Y-axis transmission wheel and the Y-axis rotating wheel.

[0014] Furthermore, the inner side of the conveying track is provided with an upper limiting part, and the upper end of the track base is provided with a lower limiting part, the lower limiting part being movable within the upper limiting part.

[0015] The present invention provides a conveyor track structure with the following advantages:

[0016] 1. The conveyor track structure of this utility model, by setting a first conveyor component and a second conveyor component on the conveyor track, i.e. a double conveyor belt design, can realize the board waiting function. When the printed PCB board is conveyed out, the next PCB board can be put in at the same time, without waiting for the PCB board to go out before the board is put in, reducing waiting time, improving production efficiency, and is highly practical.

[0017] 2. This utility model can handle PCB boards of different thicknesses and can achieve automatic height adjustment to meet the printing needs of various PCB boards. It connects to a lifting synchronous wheel via two lead screw shafts and is synchronously connected via a lifting synchronous belt. The middle lifting transmission wheel is connected to the lifting drive component. The lifting drive component drives the lifting transmission wheel to rotate, which, in conjunction with the lifting synchronous belt, lifting transmission wheel, and lifting synchronous wheel, drives the lead screw shaft to rotate. The rotation of the lead screw shaft drives the lead screw nut to move up and down, which in turn drives the conveyor track to move up and down, thereby realizing the lifting and lowering of the conveyor track. This adjustment can accommodate products of different thicknesses, making it flexible, convenient, and highly practical. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the product of this utility model will be further described in detail below with reference to the embodiments and accompanying drawings.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figure 1 and Figure 2As shown, a novel conveying track structure includes a support platform 1. Y-axis sliding components 2 are provided on both sides of the support platform 1 along the Y-axis direction. Track bases 3 are provided on both sides of the support platform 1 along the X-axis direction. A conveying track 4 is provided above the track bases 3. A first conveying component 5, a second conveying component 6, and a lifting adjustment component 7 are installed on the conveying track 4. The first conveying component 5 is located on one side of the second conveying component 6 along the X-axis direction. The upper end of the lifting adjustment component 7 is connected to the conveying track 4, and the lifting adjustment component 7 can drive the conveying track 4 to move up and down along the Z-axis direction.

[0032] It should be noted that this utility model, by setting a first conveyor component 5 and a second conveyor component 6 on the conveyor track 4, i.e., a dual conveyor belt design, can realize the board waiting function. When the printed PCB board is conveyed out, the next PCB board can be put in, without waiting for the PCB board to go out before it is put in, which improves the production efficiency and has strong practicality.

[0033] like Figure 2 and Figure 3 As shown, the first conveying assembly 5 includes a first driving member 8 and a first conveying synchronous wheel 9. The first driving member 8 is fixed on the side of the conveying track 4 away from the support platform 1, and the output end of the first driving member 8 passes through the support platform 1 and connects to the first conveying synchronous wheel 9. In this embodiment, the first driving member 8 can be a motor. The first driving member 8 drives the first conveying synchronous wheel 9 to rotate.

[0034] like Figure 3 As shown, the first conveying assembly 5 further includes a first conveyor belt 10, a plurality of first conveying synchronous pulleys 11, a plurality of first synchronous pulleys 12, and a plurality of first supporting synchronous pulleys 13. The first conveyor belt 10, the first conveying synchronous pulleys 11, the first synchronous pulleys 12, and the first supporting synchronous pulleys 13 are all mounted on the side of the conveying track 4 near the supporting platform 1. The first conveyor belt 10 is wound around the first conveying synchronous pulleys 11, 12, and 13. The second conveying assembly 6 has the same structure as the first conveying assembly 5, so it will not be described in detail here.

[0035] It should be noted that when the first driving component 8 drives the first conveying synchronous wheel 9 to rotate, the PCB board is conveyed in cooperation with the first conveying synchronous wheel 11, the first synchronous wheel 12, and the first supporting synchronous wheel 13. The first conveying synchronous wheel 11, the first synchronous wheel 12, and the first supporting synchronous wheel 13 are all mounted on the conveying track 4 via rotating shafts.

[0036] like Figure 3 and Figure 5As shown, the lifting adjustment assembly 7 includes a lifting drive component 14, a lifting timing belt 15, a lifting transmission wheel 16, and several lifting timing wheels 17. The lifting drive component 14 is fixed on the lower track base 3. The output end of the lifting drive component 14 passes through the track base 3 and connects to the lifting transmission wheel 16. The lifting timing wheels 17 are located on both sides of the lifting transmission wheel 16. The lifting timing belt 15 is wound around the lifting transmission wheel 16 and the lifting timing wheels 17. In this embodiment, the lifting drive component 14 can be a motor.

[0037] like Figure 5 and Figure 7 As shown, the lifting adjustment assembly 7 also includes a lead screw shaft 18, a lead screw nut 19, a bearing, and a clamping roller 20. The lead screw nut 19 is threadedly fitted onto the lead screw shaft 18. The upper end of the lead screw nut 19 is connected to the conveying track 4. The bearing is located between the lead screw nut 19 and the lifting synchronous wheel 17. The lower end of the lead screw shaft 18 is connected to the lifting synchronous wheel 17. The rotation of the lifting synchronous wheel 17 drives the lead screw shaft 18 to rotate.

[0038] It should be noted that this utility model can handle PCB boards of different thicknesses and can achieve automatic height adjustment to meet the printing needs of various PCB boards. It is connected to the lifting synchronous wheel 17 by two lead screw shafts 18 and synchronously connected by the lifting synchronous belt 15. The middle lifting transmission wheel 16 is connected to the lifting drive component 14. The lifting drive component 14 drives the lifting transmission wheel 16 to rotate. With the cooperation of the lifting synchronous belt 15, the lifting transmission wheel 16 and the lifting synchronous wheel 17, the lead screw shaft 18 is driven to rotate. The rotation of the lead screw shaft 18 drives the lead screw nut 19 to move up and down. The up and down movement of the lead screw nut 19 drives the transmission track 4 to move up and down, thereby realizing the lifting and lowering of the transmission track 4, and thus adjusting it to adapt to products of different thicknesses.

[0039] like Figure 5 As shown, the lifting adjustment assembly 7 also includes a guide rail 21, a slider 22, and a guide connecting block 23. The guide rail 21 is fixedly installed on the track base 3. The slider 22 is slidably connected to the guide rail 21. One side of the slider 22 is connected to the guide connecting block 23. The upper end of the guide connecting block 23 is connected to the conveying track 4. A limiting protrusion 24 is provided on one side of the guide connecting block 23. When the slider 22 slides up and down along the guide rail 21, it can drive the conveying track 4 to move up and down.

[0040] like Figure 4 As shown, the lifting adjustment assembly 7 also includes a limiting block 25, which is fixed on the lower track base 3. A limiting hole is provided on the inner side of the limiting block 25, and the limiting protrusion 24 of the guide connecting block 23 can slide up and down in the limiting hole.

[0041] It should be noted that the cooperation of the guide rail 21, slider 22, guide connecting block 23 and limit block 25 can restrict the rotation of the lead screw nut 19, so that the lead screw nut 19 can only move up and down, thereby driving the transmission track 4 to adjust the height. At the same time, it can also improve the stability of the up and down movement process, thereby improving the overall working stability.

[0042] like Figures 1 to 4 As shown, the Y-axis sliding assembly 2 includes a Y-axis slide rail 26 and a Y-axis sliding block 27. The Y-axis slide rail 26 is symmetrically installed on the support platform 1, and the Y-axis sliding block 27 is slidably connected to the Y-axis slide rail 26. The upper end of the Y-axis sliding block 27 is connected to the track base 3.

[0043] like Figures 1 to 4 As shown, the Y-axis sliding assembly 2 also includes a Y-axis lead screw 28 and a slide rod connecting seat 29. The Y-axis lead screw 28 is installed at the lower end of the support platform 1. A nut bracket 30 is threaded onto the Y-axis lead screw 28. One side of the nut bracket 30 is connected to the slide rod connecting seat 29. The upper end of the slide rod connecting seat 29 is connected to the track base 3.

[0044] like Figures 1 to 4 As shown, the Y-axis sliding assembly 2 further includes a Y-axis sliding drive 31, a Y-axis synchronous belt 32, a Y-axis transmission wheel 33, several Y-axis synchronous wheels 34, and several Y-axis rotating wheels 35. The Y-axis sliding drive 31 is fixed to the lower end of the support platform 1, and its output end is connected to the Y-axis transmission wheel 33. The Y-axis rotating wheels 35 are sleeved on one end of the Y-axis lead screw 28, and the Y-axis synchronous belt 32 is wound around the Y-axis transmission wheel 33 and the Y-axis rotating wheels 35. In this embodiment, the Y-axis sliding drive 31 can be a motor.

[0045] It should be noted that the Y-axis sliding component 2 can drive the track base 3 on one side to move along the Y-axis direction, thereby driving the conveyor track 4 to move along the Y-axis direction, thereby adjusting the width. This allows it to adapt to PCB boards of various sizes for printing, making it flexible and convenient to use.

[0046] like Figure 6 As shown, the inner side of the conveying track 4 is provided with a limiting upper part 36, and the upper end of the track base 3 is provided with a limiting lower part 37. The limiting lower part 37 is located inside the limiting upper part 36, and the conveying track 4 and the track base 3 are connected in a movable limiting insertion.

[0047] It should be noted that when the height adjustment component moves the conveyor track 4 upward, the lower limit 37 moves away from the upper limit 36. After printing is completed, the lifting adjustment component 7 moves the conveyor track 4 back to its original position, and the lower limit 37 is located within the upper limit 36.

[0048] like Figures 1 to 4 As shown, a baffle 38 is also installed on the track base 3, which is used to improve the stability of the PCB board during printing.

[0049] like Figure 1 As shown, the conveying track 4 is also provided with several steel mesh vacuum holes 39, which firmly fix the steel mesh and PCB board on the printing platform by vacuum adsorption, ensuring that there is no displacement or shaking during the printing process, thereby ensuring printing accuracy.

[0050] It should be noted that printing platforms are typically equipped with a vacuum system, including a vacuum pump and vacuum tubing 40. The stencil vacuum holes 39 are connected to the vacuum pump via the vacuum tubing 40, forming a closed vacuum channel. When the vacuum pump starts, it extracts air from the stencil vacuum holes 39 and the connected channel, creating a negative pressure environment in that area. Because the stencil vacuum holes 39 are in a vacuum state with extremely low pressure, while the area where the PCB board contacts the stencil is open to the outside atmosphere and has relatively high pressure, this pressure difference ensures that the PCB board is tightly adhered to the stencil, preventing movement or shifting during printing and guaranteeing printing accuracy and quality.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Those skilled in the art can readily implement the present utility model according to the accompanying drawings and the above description. However, any modifications, alterations, or equivalent changes made by those skilled in the art without departing from the scope of the present utility model's technical solution, based on the disclosed technical content, are all equivalent embodiments of the present utility model. Furthermore, any equivalent changes, alterations, or evolutions made to the above embodiments based on the essential technology of the present utility model still fall within the technical solution of the present utility model.
