Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit boards, and in particular to a PCB circuit board pushing structure. Background Art

[0002] With the development of science and technology, PCB circuit boards are used more and more widely in life. After the PCB circuit boards are processed, they need to be pushed from the conveyor to the PCB circuit board storage rack for storage to prevent improper storage of the PCB circuit boards, which may damage the electronic components on the PCB circuit boards and affect their subsequent use.

[0003] After searching, Chinese patent application number CN202320688624.1 discloses a circuit board conveying device with a pushing function. When pushing the material, the utility model uses an infrared detector to detect the position of the circuit board, and then the front end of the pushing plate is lifted under the action of a spring and aligned with the rear end of the circuit board. Then the pushing assembly continues to move forward, and the front end of the pushing plate abuts against the circuit board and continues to move, using inertia to complete a pushing operation. However, the pushing plate needs to move back and forth a long distance during the pushing process, so the interval between two pushing operations is long, which reduces the work efficiency. At the same time, when the PCB circuit board is large and the distance between the two mounting plates needs to be adjusted, the above-mentioned device can only be adjusted from one side. After the adjustment, the pushing plate is not located in the middle. Therefore, it is easy to cause uneven force on the PCB circuit board during the pushing process, which reduces the pushing effect. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 The utility model provides a technical solution: a PCB circuit board pushing structure, including a bottom plate 10, movable plates 20 arranged on the left and right sides of the bottom plate 10, a conveying belt 30 arranged on one side of the movable plate 20 for conveying the PCB circuit board, and an infrared detector 40 arranged on the left movable plate 20, a base 50 and a support frame 60 are arranged on the top of the bottom plate 10, a double-axis motor 51 is arranged on the top of the base 50, and the output shafts of the double-axis motor 51 are fixed with adjusting threaded rods 5101, and the two adjusting threaded rods 5101 respectively penetrate the two movable plates 20.

[0028] It should be noted that the conveyor belt 30 is used to transport the PCB circuit board, and the infrared detector 40 can be used to detect the position of the PCB circuit board.

[0029] Among them, the left and right sides of the two movable parts 20 are both provided with first limiting rods 5102, and the side of the base 50 is provided with a circular hole for the left first limiting rod 5102 to pass through, and the support frame 60 and the base 50 are located on the same horizontal line.

[0030] At the same time, a threaded hole is opened on the left side of the movable plate 20, and the adjusting threaded rod 5101 passes through the threaded hole and is threadedly connected thereto. The threads on the outer surfaces of the two adjusting threaded rods 5101 are in opposite directions. The dual-axis motor 51 can drive the adjusting threaded rod 5101 to rotate forward and backward. During the rotation, the distance between the two movable plates 20 can be adjusted, which is convenient for adjustment according to the size of the PCB circuit board.

[0031] See also Figure 2 A driving motor 61 is disposed at the center of the inner bottom wall of the support frame 60, a screw rod 6101 is fixed to the output shaft of the driving motor 61, a connecting seat 6102 is disposed on the outer surface of the screw rod 6101, and a first connecting arm 6103 is disposed on one side of the connecting seat 6102,

[0032] Among them, a second connecting arm 6104 is provided at the other end of the connecting seat 6102, and the inner bottom wall of the support frame 60 is provided with a second limiting rod 6105 that penetrates to the top of the second connecting arm 6104. The second limiting rod 6105 can limit the connecting seat 6102 to prevent the connecting seat 6102 from rotating with the screw rod 6101 during the rotation process.

[0033] At the same time, a screw hole is opened at the center of the top surface of the connecting seat 6102, and the screw rod 6101 passes through the screw hole and is threadedly connected thereto. The driving click 61 drives the screw rod 6101 to rotate, thereby driving the connecting seat 6102 to move up and down, further facilitating the normal pushing work.

[0034] In addition, the first connecting arm 6103 is in an "L" shape, so that the fixing frame 6202 is located above the connecting seat 6102, which is convenient for pushing materials. The top end of the screw rod 6101 is lower than the bottom end of the conveyor belt 30, avoiding the PCB circuit board from interfering with the fixing frame 6202 during transportation. The pushing plate 6205 is in a "semi-cylindrical" shape.

[0035] See also Figure 3 A fixing frame 6201 is provided on one side of the first connecting arm 6103, and fixing rods 6202 are provided on both the left and right sides of the fixing frame 6201. A moving plate 6203 is provided on the outer surfaces of the two fixing rods 6202, and a return spring 6204 is provided on one end of the outer surface of the fixing rod 6202. A push plate 6205 is provided on one side of the moving plate 6203.

[0036] Among them, a fixing hole 6206 is opened on the left side of the support frame 60, and the two ends of the reset spring 6204 are abutted between the moving plate 6203 and the inner wall of the fixed frame 6201. The elastic potential energy of the reset spring 6204 can be used to enable the push plate 6205 to push the PCB circuit board.

[0037] See also Figure 4 A driving bevel gear 6301 is disposed on the outer surface of the screw rod 6101 , a driven bevel gear 6302 is disposed on one side of the driving bevel gear 6301 , a rotating rod 6303 is disposed at one end of the driven bevel gear 6302 , and the rotating rod 6303 is rotatably connected to the inner wall of the support frame 60 .

[0038] Among them, a winding wheel 6304 is arranged on the outside of the rotating rod 6203, a ring 6305 is arranged on one side of the movable plate 6203, two guide wheels 6306 are arranged on one side of the fixed frame 6201, and the right guide wheel 6306 is arranged on the left side of the fixing hole 6206. A pull rope 6307 is arranged on the ring 6305, which can reduce the friction between the pull rope 6307 and increase its service life.

[0039] At the same time, the left guide wheel 6306 is aligned with the fixing hole 6206, and the other end of the pull rope 6307 is wrapped around the outer surface of the winding wheel 6304.

[0040] In addition, the pull rope 6307 passes through the two fixing holes 6206 and fits with the two guide wheels 6306 respectively.

[0041] Specifically, the working principle of this PCB circuit board pushing structure is as follows: when in use, first adjust the distance between the two movable plates 20 according to the size of the PCB circuit board, specifically, drive the two adjusting threaded rods 5101 to rotate through the dual-axis motor 51, and the adjusting threaded rods 5101 can move the two movable plates 20 to the opposite side or the opposite side during the rotation until they are adjusted to a suitable position, and then use the conveyor belt 30 to transport the PCB circuit board. When the PCB circuit board is transported to the right end of the conveyor belt 30, the infrared detector 40 detects the position of the PCB circuit board and starts the drive motor 61. At this time, the screw rod 6101 rotates and drives the fixing frame 6201 to move upward The driven bevel gear 6302 rotates, and the driven bevel gear 6302 rotates. The driven bevel gear 6302 rotates, and the winding wheel 6304 rotates. At this time, the pull rope 6307 is gradually loosened from the outer surface of the winding wheel 6304. At the same time, the push plate 6205 moves to the side close to the PCB circuit board under the action of the reset spring 6204 and completes a pushing process. After completing a pushing process, the driving motor 61 drives the screw rod 6101 to rotate in the opposite direction, and further drives the fixed frame 6201 to move to the initial position. During this process, the winding wheel 6304 reels the pull rope 6307.

[0042] It should be noted that the specific models and specifications of the dual-axis motor 51, drive motor 61, conveyor belt 30 and infrared detector 40 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0043] The power supply and principles of the dual-axis motor 51, the drive motor 61, the conveyor belt 30 and the infrared detector 40 are clear to those skilled in the art and will not be described in detail herein.
