Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing equipment, in particular to a PCB board processing alignment device. Background Art

[0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board, printed circuit board, which is an important electronic component. PCB board is the support of electronic components and the provider of electrical connections for electronic components. During the processing of PCB board, the position of PCB circuit board needs to be adjusted. Some existing adjustment devices are manually operated, but this not only wastes time, but also manual operation is prone to errors. Therefore, some alignment devices that do not require manual adjustment of PCB board position have appeared.

[0003] For example, a Chinese utility model patent disclosed in the Chinese patent publication with publication number CN213403668U and authorization announcement date June 8, 2021 discloses a PCB board processing alignment device, including a bracket, a rectangular alignment platform supported on the top surface of the bracket, an adjustment arm and an adjustment spring arranged on the side of the alignment platform; the adjustment arm includes four and is respectively located in the middle position of the four sides of the alignment platform, the adjustment arm is slidably connected with the alignment platform, each adjustment arm extends perpendicular to the corresponding side of the alignment platform and its end away from the alignment platform exceeds the upper surface of the alignment platform; the adjustment spring includes four and is matched with the four said adjustment arms respectively, one end of each adjustment spring is fixed to the end of the corresponding adjustment arm away from the alignment platform, and the other end is fixed to the middle position of the corresponding side of the alignment platform,

[0004] However, in actual use, although the above device adjusts the position of the PCB board by arranging two groups of adjustment arms and two groups of adjustment springs on the side of the alignment platform, the arm head of the adjustment arm can only move to the edge of the alignment platform. In this way, when the size of the PCB board is smaller than the alignment platform, the adjustment arm cannot clamp and position the PCB board, thereby reducing the application range of the device. In addition, when the device clamps and positions the PCB board, the adjustment arm is driven to move by the tension of the contraction and rebound of the adjustment spring, thereby achieving the clamping and positioning of the PCB board. However, with such a design, it is more troublesome for people to put the PCB board on the alignment platform. Four people are required to stand on the four sides of the alignment platform respectively and pull the adjustment arm at the same time so that the PCB board can be smoothly placed on the alignment platform. This method not only wastes time, but also wastes manpower, greatly reducing work efficiency. Utility Model Content

[0005] The utility model aims to provide a PCB board processing alignment device to solve the problem that the existing PCB board is not convenient for rapid positioning during the processing.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-5The utility model provides a technical solution: a PCB board processing alignment device, including a workbench 1, a first motor 2 is fixedly connected to the top center of the workbench 1, a gear 3 is fixedly connected to the output end of the first motor 2, racks 4 are respectively meshed and connected at both ends of the gear 3, a support rod 5 is fixedly connected at one end of the rack 4, the top of the support rod 5 extends above the workbench 1 and is slidably connected to the workbench 1, a moving plate 6 is fixedly connected to the top of the support rod 5, L-shaped plates 7 are respectively slidably connected at both ends of the moving plate 6, a second motor 8 is fixedly connected to one end of the moving plate 6, a bidirectional threaded rod 9 is fixedly connected to the output end of the second motor 8, and the bidirectional threaded rod 9 is threadedly connected to the L-shaped plate 7,

[0024] In this embodiment, one end of the L-shaped plate 7 is parallel to the moving plate 6, and the other end is perpendicular to the moving plate 6, and the inner sides of the L-shaped plates 7 at both ends of the moving plate 6 are both oriented toward the middle of the moving plate 6, and at the same time, the L-shaped plates 7 on the two moving plates 6 are both oriented toward the middle of the workbench 1, so that the four L-shaped plates 7 can smoothly clamp and position the PCB board. In addition, the bidirectional threaded rod 9 is arranged on the side of the moving plate 6 away from the L-shaped plate 7, and the two L-shaped plates 7 are symmetrically arranged at both ends of the bidirectional threaded rod 9.

[0025] During operation, the PCB board is first placed between the two movable plates 6 on the top of the workbench 1, and then the first motor 2 is turned on. Under the drive of the first motor 2, the gear 3 will rotate, thereby driving the two racks 4 to move synchronously in the opposite direction. When the racks 4 move, the support rod 5 will be driven to move, and then the movable plate 6 will move. In this way, the two movable plates 6 will move synchronously in the opposite direction under the drive of the first motor 2. During the movement of the movable plate 6, the L-shaped plate 7 will be driven to move. When the side of the L-shaped plate 7 parallel to the movable plate 6 contacts the PCB board, the two ends of the PCB board can be adjusted and positioned. In actual operation, after the L-shaped plate 7 clamps the two ends of the PCB board, the first motor 2 can be turned on again to drive the gear 3 to rotate in the opposite direction, thereby driving The movable L-shaped plate 7 moves a little distance in the direction away from the PCB board (the length of the distance needs to be less than the length of the side wall of the L-shaped plate 7 at one end perpendicular to the movable plate 6). The purpose of this is to facilitate the L-shaped plate 7 to adjust the positions of the other two ends of the PCB board more easily, and avoid the situation where the other two ends are difficult to adjust the positions due to the L-shaped plate 7 clamping the two ends of the PCB board. Then, the two-way threaded rod 9 is driven to rotate by the second motor 8, thereby driving the two L-shaped plates 7 to move synchronously in the opposite direction. When the side of the L-shaped plate 7 perpendicular to the movable plate 6 contacts the PCB board, the other two ends of the PCB board can be adjusted and positioned. In this way, under the mutual cooperation of the first motor 2 and the second motor 8, the four L-shaped plates 7 can clamp and position the PCB board.

[0026] The workbench 1 is provided with a first through groove 10 just above the rack 4, and the first through groove 10 is slidably connected to the support rod 5. In this embodiment, the design of the first through groove 10 allows the top of the support rod 5 to smoothly extend to the top of the workbench 1 and to be smoothly slidably connected to the workbench 1, so that when the first motor 2 drives the gear 3 to rotate, the rack 4 can move smoothly, and drive the support rod 5 to move, and then drive the movable plate 6 to move.

[0027] The first slide grooves 11 are respectively provided at the two ends of the top of the workbench 1, and the first sliders 12 are respectively fixedly connected at the two ends of the bottom of the movable plate 6. The first slide grooves 11 are slidably connected to the first sliders 12. In the present embodiment, since the two racks 4 are respectively arranged on both sides of the gear 3, the rack 4 is not located at the center line of the movable plate 6, and the support rod 5 is fixedly connected to the top of the rack 4. Therefore, the connection between the support rod 5 and the movable plate 6 is not the center line of the bottom of the movable plate 6, so the support rod 5 may still shake when driving the movable plate 6 to move. Therefore, by respectively opening the first slide grooves 11 at the two ends of the top of the workbench 1, and arranging the first sliders 12 at the two ends of the bottom of the movable plate 6, the first slide grooves 11 and the first sliders 12 are slidably connected together, so that the movable plate 6 will be more stable when moving.

[0028] A second through groove 13 is provided on the top of the movable plate 6, and a connecting block 14 is fixedly connected to the top of one end of the L-shaped plate 7 on the movable plate 6. The connecting block 14 is slidably connected to the second through groove 13, and the connecting block 14 is threadedly connected to the bidirectional threaded rod 9. In the present embodiment, since the movement of the two L-shaped plates 7 is achieved by the second motor 8 driving the bidirectional threaded rod 9 to rotate, and the L-shaped plate 7 and the bidirectional threaded rod 9 are respectively located on both sides of the movable plate 6, in order to allow the bidirectional threaded rod 9 to be smoothly threadedly connected to the L-shaped plate 7, a second through groove 13 is opened on the movable plate 6, and a connecting block 14 is set on the L-shaped plate 7, so that one end of the connecting block 14 extends to one end of the bidirectional threaded rod 9, so that the L-shaped plate 7 can be smoothly threadedly connected to the bidirectional threaded rod 9.

[0029] A collar 15 is fixedly connected to one end of the connecting block 14 away from the L-shaped plate 7, and the collar 15 is threadedly connected to the bidirectional threaded rod 9. In this embodiment, the design of the collar 15 allows the connecting block 14 to be smoothly threadedly connected to the bidirectional threaded rod 9, wherein an internal thread is provided in the collar 15, so that the collar 15 can be smoothly threadedly connected to the bidirectional threaded rod 9.

[0030] The movable plate 6 is provided with a second slide groove 16 below the second through groove 13, and the L-shaped plate 7 is fixedly connected with a second slider 17 below the connecting block 14. The second slide groove 16 is slidably connected to the second slider 17. In this embodiment, in order to make the L-shaped plate 7 move more stably under the drive of the bidirectional threaded rod 9, a second slide groove 16 is opened on the movable plate 6, and a second slider 17 is set on the L-shaped plate 7, so that the second slide groove 16 and the second slider 17 are slidably connected together, so that the L-shaped plate 7 will be more stable when moving.

[0031] A rubber pad 18 is provided on the inner side of the L-shaped plate 7. In this embodiment, in order to prevent the L-shaped plate 7 from damaging the PCB board when clamping and positioning the PCB board, a rubber pad 18 is provided on the inner side of the L-shaped plate 7 to protect the PCB board.

[0032] Support legs 19 are fixedly connected to the four corners of the bottom of the workbench 1. In the present embodiment, since the first motor 2, gear 3, rack 4 and other structures are arranged at the bottom of the workbench 1, in order to allow the first motor 2, gear 3, rack 4 and other structures to operate normally, four support legs 19 are arranged at the bottom of the workbench 1, so that the first motor 2, gear 3, rack 4 and other structures are kept away from the ground, so that the first motor 2, gear 3, rack 4 and other structures can operate normally.

[0033] Working principle: When in use, first place the PCB board between the two movable plates 6 on the top of the workbench 1, and then turn on the first motor 2. Driven by the first motor 2, the gear 3 will rotate, thereby driving the two racks 4 to move synchronously in the opposite direction. When the racks 4 move, the support rods 5 will be driven to move, and then the movable plate 6 will move. In this way, the two movable plates 6 will move synchronously in the opposite direction under the drive of the first motor 2. During the movement of the movable plate 6, the L-shaped plate 7 will be driven to move. When the side of the L-shaped plate 7 parallel to the movable plate 6 contacts the PCB board, the two ends of the PCB board can be adjusted and positioned. In actual operation, after the L-shaped plate 7 clamps the two ends of the PCB board, the first motor 2 can be turned on again to drive the gear 3 to rotate in the opposite direction. Then, the L-shaped plate 7 is driven to move a certain distance away from the PCB board (the length of the distance needs to be less than the length of the side wall of the L-shaped plate 7 at one end perpendicular to the movable plate 6). The purpose of this is to facilitate the L-shaped plate 7 to adjust the positions of the other two ends of the PCB board more easily, and to avoid the situation where the other two ends are difficult to adjust the positions due to the L-shaped plate 7 clamping the two ends of the PCB board. Then, the second motor 8 drives the bidirectional threaded rod 9 to rotate, thereby driving the two L-shaped plates 7 to move synchronously in the opposite direction. When the side of the L-shaped plate 7 perpendicular to the movable plate 6 contacts the PCB board, the other two ends of the PCB board can be adjusted and positioned. In this way, under the mutual cooperation of the first motor 2 and the second motor 8, the four L-shaped plates 7 can clamp and position the PCB board.
