Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-6 , a PCB pin quick plug-in device, comprising a workbench 1, four guide tubes 2 are fixedly connected to the top of the workbench 1, and a support spring 201 fixedly connected to the top of the workbench 1 is wound on the surface of the guide tube 2, one end of the support spring 201 is fixedly connected to a U-shaped moving plate 3 slidably connected to the surfaces of multiple guide tubes 2, a PCB board body 13 is arranged in the U-shaped moving plate 3 (a plurality of through holes are arranged on the PCB board body 13, which facilitates the pins of light-emitting diodes to pass through, so that the light-emitting diodes are connected to the PCB board body 13), a relatively arranged U-shaped card frame 301 is fixedly connected to the inner side of the U-shaped moving plate 3, the PCB board body 13 is located between the two U-shaped card frames 301, a compression spring 203 (the elastic coefficient of the compression spring 203 is greater than the elastic coefficient of the support spring 201) wound on the surface of the guide tube 2 is fixedly connected to the top of the U-shaped moving plate 3, and a driving plate 4 slidably connected to the guide tube 2 is fixedly connected to the top of the guide tube 2. A limit plate 202 in contact with the top of the driving plate 4 is fixedly connected to the top of the guide tube 2.

[0023] Furthermore, one end of the driving plate 4 is fixedly connected to a relatively arranged sliding rod 8, and a connecting rod 9 is fixedly connected between the sliding rods 8 (the driving plate 4, the U-shaped movable plate 3 and the PCB board body 13 are driven downward by the connecting rod 9 and the sliding rod 8, so that the pins of the light-emitting diode are connected to the PCB board body 13), and the top of the workbench 1 is fixedly connected to a vertical plate 7, and one end of the vertical plate 7 is provided with a sliding groove that is slidably connected to the sliding rod 8.

[0024] It should be noted that: a mounting groove is provided at one end of the driving plate 4, in which a rotating shaft 5 is rotatably connected, one end of the rotating shaft 5 passes through the driving plate 4 (the part of the rotating shaft 5 passing through the driving plate 4 is provided with anti-slip grooves, and its large friction force can prevent the cam 6 from rotating under the action of its own weight), a plurality of cams 6 are fixedly connected to the surface of the rotating shaft 5 (the cam 6 can bend the pins of the light-emitting diodes passing through the through holes), a movable groove slidably connected to the rotating shaft 5 is provided at one end of the vertical plate 7, a gear ring 501 is fixedly connected to the surface of the rotating shaft 5, and a tooth plate 701 is fixedly connected to one end of the vertical plate 7 (the gear, the rotating shaft 5 and the cam 6 are driven to rotate through the tooth plate 701 to bend the pins of the light-emitting diodes).

[0025] It is worth noting that: a fixed plate 10 is fixedly connected to the top of the workbench 1, an electric push rod 11 is fixedly connected to one end of the fixed plate 10, a placement frame 12 is fixedly connected to one end of the electric push rod 11, a plurality of arc frames 1202 are fixedly connected to the bottom end of the placement frame 12 (the arc frames 1202 are used to place light-emitting diodes, and the light-emitting diodes in the arc frames 1202 are placed inverted), and a resistance plate 1201 is fixedly connected to one end of the placement frame 12.

[0026] A further advantage of adopting the above method is that the above device does not require the staff to constantly flip the PCB board body 13, and does not require the staff to constantly bend the pins of the light-emitting diodes, which saves time and labor while improving the connection efficiency between the PCB board body 13 and the light-emitting diode pins.

[0027] It is worth noting that the electric push rod 11 pushes the placement frame 12 and the light-emitting diode in the placement frame 12 to move, and drives the resistance plate 1201 to move until the resistance plate 1201 is moved to contact with the vertical plate 7. At this time, the pin of the light-emitting diode is located below the via hole.

[0028] When the utility model is in use: when it is necessary to connect the light-emitting diodes with the PCB board body 13, the staff puts a plurality of light-emitting diodes upside down in the arc frame 1202, and then the staff starts the electric push rod 11, the electric push rod 11 pushes the placement frame 12 and the light-emitting diodes in the arc frame 1202 to move, and drives the contact plate 1201 to move, and moves the contact plate 1201 to contact with the vertical plate 7, at this time, the pin of the light-emitting diode is located below the through hole, and then the staff holds the connecting rod 9 and moves the connecting rod 9 downward, drives the driving plate 4 to move downward through the connecting rod 9 and the sliding rod 8, and the driving plate 4 moves downward and presses the U-shaped moving plate 3 through the compression spring 203, so that the U-shaped moving plate 3 moves downward and drives the PCB board body 13 to move downward (the downward movement of the U-shaped moving plate 3 will compress the supporting spring 201), and moves the PCB board body 13 downward until it contacts with the light-emitting diode, and at this time, the pin of the light-emitting diode passes through the through hole on the PCB board body 13;

[0029] When the drive plate 4 moves downward, the gear ring 501 contacts the tooth plate 701 and the gear ring 501 continues to move downward. The gear ring 501 rotates under the action of the tooth plate 701. The rotation of the gear ring 501 drives the shaft 5 and multiple cams 6 to rotate. The rotation of the cam 6 pushes the pins passing through the through holes to tilt, causing the pins to bend. Then the staff loosens the connecting rod 9, so that the U-shaped movable plate 3 and the PCB board body 13 are reset under the action of the supporting spring 201 and the driving plate 4 under the action of the compression spring 203, and drives the light-emitting diode connected to the PCB board body 13 to move upward. Then the staff takes the PCB board body 13 out of the two U-shaped card frames 301 and welds it. The above device does not require the staff to constantly flip the PCB board body 13, and does not require the staff to constantly bend the pins of the light-emitting diodes. It saves time and effort while improving the connection efficiency between the PCB board body 13 and the light-emitting diode pins.

[0030] The staff can place different light-emitting diodes and PCB board body 13 in the arc frame 1202 and the U-shaped card frame 301, and then connect them.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
