[0032] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0033] In the following description, the example details are given to provide a deeper understanding of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. It should be understood that the specific embodiments are only used to explain the utility model, and are not used to limit the utility model.

[0034] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0035] In order to solve the above-mentioned technical problems, the present application provides a PCB board auxiliary processing structure based on a screw structure, please refer to the attached Figure 1 To Attachment Figure 6, including a base, a transport roller 1 and a screw structure 5: sliding guide rails are arranged on both sides of the base 5; a plurality of drive motors 6 are arranged at one end of the base; the number of transport rails 1 matches the number of drive motors 6, and a first mounting frame 14 and a second mounting frame 15 are arranged at both ends of the transport rail 1, and the first mounting frame 14 and the second mounting frame 15 are connected to the sliding guide rails correspondingly; the first mounting frame 14 is provided with a through hole matching the number of drive motors 6; the number of screw structures 5 matches the number of drive motors 6, one end of any screw structure 5 is connected to the output shaft of the drive motor 6 correspondingly, and the other end is assembled together on the sliding guide rail. On the mounting part; any screw rod structure 5 is sleeved with a screw nut part 51, and multiple screw rod structures 5 are jointly penetrated on all the first mounting frames 14 through perforations, and the screw nut part 51 is fixedly connected to any first mounting frame 14; during specific operation, multiple screw rod structures 5 rotate in the first direction and the second direction following the output shaft of the drive motor 6, and the spacing between the multiple transport rollers can be adjusted by means of the screw nut part 51, thereby ensuring the basic function of being able to adapt to the transportation of PCB boards 4 of different widths, and multiple drive motors can be uniformly assembled at one end of the base, which is convenient for technical personnel to carry out inspection and maintenance.

[0036] In a specific solution, any driving motor 6 is connected to the screw structure 5 via a transmission chain; the transmission chain enables the driving motors to be more centrally arranged in the same area.

[0037] After the transportation of the completed PBC board, the PCB board 4 needs to be clamped to ensure that the processes such as patch can be carried out smoothly. Therefore, it also includes a lifting platform 2 located between any two transportation rails; the two sides of the PCB board 4 are placed on the two transportation rails 1 for transportation; one side of any transportation rail 1 is also provided with a limit plate 12, and the other side is provided with a top plate device 3, and the top plate device 3 is provided with a pressure sensor on the side close to the lifting platform; it can be understood that the screw structure 5, the sliding guide rail and the transportation rail 1 are matched to realize the adaptive transportation of PCB boards of different widths, and then the lifting platform 2, the limit plate 12 and the top plate device 3 are used to realize the PCB boards 4 of different thicknesses. The PCB board 4 is clamped for subsequent processing such as patching. When working, the extrusion pressure sensor 31 is lifted by the lifting platform 2 and indirectly abuts the PCB board 4. The pressure sensor 31 collects the extrusion pressure of the lifting platform 2. At this time, the limit plate 12 and the top plate device 3 clamp the PCB board 4 together. When the pressure collected by the pressure sensor 31 reaches the expected pressure, the lifting platform 2 stops lifting and maintains the lifting height until the PCB board 4 is processed. There is no need for technicians to input the clamping distance multiple times as in the prior art to adapt the thickness of the PCB board 4 for clamping, thereby achieving a higher degree of automated production effect, effectively improving the production efficiency of PCB boards, and reducing the difficulty of using the equipment.

[0038] In the specific scheme, the transport track 1 includes a conveyor belt 11; the area between the limit plate 12 and the first surface of the conveyor belt 11 forms a transport channel; when working, the PCB board is placed on the first surface of the conveyor belt for transportation, and after the PCB board is located at the specified position, the lifting platform is lifted to force the top plate device to abut against the second surface of the conveyor belt, so that the top plate device and the limit plate jointly clamp the PCB board; it is worth mentioning that the arrangement of the conveyor belt 11 can be arranged by a power motor combined with a plurality of sets of driven wheels 27 structures, which is in the prior art, so it will not be described in detail; the lifting platform 2 rises and pushes the top plate device 3 when working, so that the push plate The device 3 moves toward the second side of the conveyor belt 11 and pushes the conveyor belt 11 until the top plate device and the limit plate jointly clamp the PCB board 4. At this time, the pressure sensor 31 constantly detects the pressure formed by the top plate device 3 abutting against the second side of the PCB board 4. When the pressure sensor 31 reaches the expected threshold value, the lifting platform 2 maintains the rising height and clamps the PCB board 12 in combination with the limit plate to realize subsequent processes such as patching. After the patching is completed, the lifting platform descends, and the conveyor track transports the PCB board that has completed the patching process, so as to automatically process the next PCB board and repeat the above processing steps.

[0039] In this embodiment, sensors 13 are provided at both ends of the transport track 1; it is not difficult to understand that the feeding state and the discharging state of the PCB board 4 can be identified and judged by the sensor 13, and a corresponding counter can be added to unify the transport quantity of the PCB board 4.

[0040] In the present embodiment, the lifting platform 2 is composed of a platform plate 21 and a plurality of lifting screw rod structures 22, and the platform plate 21 is jointly sleeved on the screw nuts of the plurality of lifting screw rod structures 22; it is not difficult to understand that any lifting screw rod structure 22 includes a threaded screw rod and a screw rod nut, the screw rod thread is sleeved on the threaded screw rod, and the screw rod nut is dispersedly fixedly assembled on the platform plate 21, and the lifting screw rod structure 22 is started, the threaded screw rod and the screw rod nut rotate relative to each other, and the screw rod nut drives the platform plate 21 to lift, and based on the dispersed screw rod nut assembly method, the platform plate 21 is not easy to tilt during the lifting process, and thus the lifting platform 2 will not be linked to the top plate device 3 to tilt against the second side of the PCB board 4, causing the PCB board 4 in transportation to tilt, or causing the pressure touch sensor to be unable to be used simultaneously.

[0041] Among them, it also includes a screw cylinder 23 whose number is equal to that of the lifting screw structure 22. The threaded screw of the lifting screw structure 22 is correspondingly assembled in the screw cylinder 23. The screw cylinder 23 is used to provide a rotational force to the threaded screw, so that the threaded screw and the screw nut seat move relative to each other. One end of the lifting screw structure 22 protruding from the screw cylinder 23 is sleeved with a synchronous wheel, and all the synchronous wheels are meshed on the same synchronous belt 24; in the preferred embodiment, it also includes a driving motor 25, which is meshed with the synchronous belt 24 to drive the lifting screw structure 22 to move synchronously; it is not difficult to understand that by rotating the driving motor 25, through The synchronous belt 24 drives all the lifting screw structures 22 to work at the same time, so that the platform plate 21 is lifted steadily and vertically to mortgage the top plate device 3, and the top plate device 3 squeezes the second side of the transmission belt to support the PCB board 4 until the transportation is completed, ensuring that the top plate device 3 will not cause the PCB board 4 to tilt when abutting, making the transportation of the PCB board 4 more stable; if tilting occurs, firstly, the pressure sensor 31 is difficult to work normally and cannot detect the lifting pressure of the lifting platform 2 on the top pressure device, then the PCB board 4 is also easily affected by the top plate device 3 and tilted, affecting the transmission.

[0042] In the actual installation process, multiple sets of lifting screw rod structures 22, drive motors 25, etc. are arranged between two transport rails 1, so the space requirement for assembly is higher. Therefore, in the present embodiment, a connecting plate 26 is also included, one side of the connecting plate 26 is commonly connected to the multiple sets of lifting screw rod structures 22, and the other side is connected to the platform plate 21; the plate area of ​​the connecting plate 26 is smaller than the plate area of ​​the platform plate 21; one side of the connecting plate 26 is directly connected to the multiple sets of lifting screw rod structures 22 to ensure vertical stability during the lifting process and prevent tilting, and then the second side of the connecting plate 26 is connected to the platform plate 21 to increase the area of ​​the actual expanded working surface, thereby ensuring that the top plate devices 3 on both sides can be lifted by the top plate devices 3.

[0043] In this embodiment, multiple sets of driven wheels 27 are also included, and the driven wheels 27 are jointly meshed with the synchronous belt 24; the driven wheels 27 can increase the rotation smoothness of the synchronous belt 24, making the simultaneous movement of the multiple sets of lifting screw structures 22 more stable, thereby making the lifting and lowering of the platform plate 21 more stable.

[0044] The advantages of the utility model are:

[0045] Multiple lead screw structures rotate in the first direction and the second direction following the output shaft of the drive motor. The spacing between the multiple transport rollers can be adjusted by means of the lead screw nut, thereby ensuring the basic function of being able to adapt to the transportation of PCB boards of different widths. Multiple drive motors can be uniformly assembled at one end of the base, which is convenient for technicians to carry out inspection and maintenance.

[0046] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
