DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a PCB double-panel cylinder edge clamping board feeding machine comprises a cabinet 1, two board feeding adjustment seats 2 are arranged above the cabinet 1, and the two board feeding adjustment seats 2 are symmetrical, and the two board feeding adjustment seats 2 form a board feeding channel, and two groups of threaded seats 3 are connected to the bottom of the two board feeding adjustment seats 2, and a group of threaded seats 3 is two, and the inner sides of the two groups of threaded seats 3 are threadedly connected with width adjustment rods 4, and the width adjustment rod 4 drives the threaded seat 3 to move position by rotating, and the width adjustment rod 4 is a forward and reverse screw, and the threaded seat 3 drives the board feeding adjustment seat 2 to move position at the same time when it is in the moving position, and the distance between the two board feeding adjustment seats 2 is changed, so as to adapt to PCB boards of different sizes and transport PCB boards of various sizes.

[0023] One side of the two board feeding adjustment seats 2 is rotatably connected with multiple board feeding conveying wheels 5, and the multiple board feeding conveying wheels 5 are arranged at equal distances. The board feeding conveying wheels 5 can provide rolling support for the PCB board to avoid friction between the PCB board and the board feeding adjustment seat 2, which causes PCB wear.

[0024] A rodless cylinder runway 6 is connected to the upper surface of the cabinet 1, and power is provided for moving the PCB board through the rodless cylinder runway 6. An alligator clip 7 is connected to the upper surface of the rodless cylinder runway 6, and an adjusting mechanism 8 is arranged inside the alligator clip 7. A first cylinder 9 is connected to the upper surface of the rodless cylinder runway 6, and power is provided for the alligator clip 7 through the first cylinder 9 so that the alligator clip 7 can be closed. The rodless cylinder runway 6 can provide power for moving the PCB board to push the PCB board to move its position. The output end of the first cylinder 9 is slidably connected to one end of the alligator clip 7. One side of the two board feeding adjustment seats 2 is connected to a support seat 10, and the inner bottom walls of the two support seats 10 are connected to a second cylinder 11. The output end of the second cylinder 11 is connected to a push block 12, and one side of the push block 12 is rotatably connected to a support plate cone wheel 13. The second cylinder 11 can provide power for moving the support seat 10, and drive the support plate cone wheel 13 to move its position while the support seat 10 moves its position.

[0025] The inner wall of the support seat 10 is connected to a guide rail 14, and a slide groove 15 is provided on the inner side of the push block 12. The inner wall of the slide groove 15 is slidably connected to the outer surface of the guide rail 14. The support seat 10 is guided by the guide rail 14 to improve its stability during sliding and provide more stable support for the push plate cone wheel.

[0026] A motor 16 is installed on one side of the cabinet 1, and the output end of the motor 16 is connected to one end of the width adjustment rod 4. The motor 16 is used as a power source to drive the width adjustment rod 4 to rotate. The outer surfaces of the two width adjustment rods 4 are connected with pulleys 17, and the outer surfaces of the pulleys 17 are sleeved with a transmission belt 18, and the pulleys 17 are connected through the transmission belt 18. When the width adjustment rod 4 rotates, the other pulley 17 is driven to rotate through the transmission belt 18. After the pulley 17 rotates, it drives the other width adjustment rod 4 to rotate synchronously, so that both ends of the feeding plate adjustment seat 2 have a driving force, which can prevent the feeding plate adjustment seat 2 from tilting and getting stuck.

[0027] The opening size of the crocodile clip 7 can be adjusted by the adjusting mechanism 8, so that the crocodile clip 7 can clamp PCB boards of different thicknesses. The adjusting mechanism 8 includes a screw rod 801, the outer surface of the screw rod 801 is threadedly connected to the inner side of the crocodile clip 7, the outer surface of the screw rod 801 is threadedly connected to an adjusting block 802, one side of the adjusting block 802 is in contact with the outer surface of the crocodile clip 7, and one end of the screw rod 801 located inside the crocodile clip 7 is connected to a pressing plate 803 for fixed-point rotation. By rotating the adjusting block 802, the pressing plate 803 can be driven to move up and down to change the clamping distance of the crocodile clip 7. The upper surface of the pressing plate 803 is connected to a guide rod. 804, the outer surface of the guide rod 804 is slidably connected to the inner side of the crocodile clip 7. When the lead screw drives the pressure plate 803 to move up and down to adjust the position, the guide rod 804 can limit the pressure plate 803 to rotate together with the lead screw 801. The outer part of the lead screw 801 is sleeved with a spring 805, one end of the spring 805 is connected to the upper surface of the pressure plate 803, and the other end of the spring 805 is connected to the inner wall of the crocodile clip 7. When the crocodile clip 7 drives the pressure plate 803 to clamp the PCB board, the pressure plate 803 pushes the spring 805 to contract. The spring 805 can play a buffering role to avoid wear on the surface of the PCB board during clamping.

[0028] It should be noted that in actual use of the device, when it is necessary to adjust the spacing between the feeding plate adjustment seats 2, first start the motor 16 to drive the width adjustment rod 4 to rotate. The width adjustment rod 4 drives the threaded seat 3 to move while rotating, and the threaded seat 3 pushes the feeding plate adjustment seat 2 to move. After the feeding plate adjustment seat 2 is adjusted to the set spacing, turn off the motor 16. When the alligator clip 7 clamps PCB boards of different thicknesses, the screw rod 801 is driven to move by rotating the adjustment block 802. When the screw moves, it also drives the pressure plate 803 to move. The pressure plate 803 changes the clamping spacing inside the alligator clip 7 by moving its position.
