Description

Technical Field

[0001] This application relates to the technical field of circuit board processing, and specifically relates to a circuit board printing and conveying device. Background Art

[0002] In the production process of circuit boards, conveying is the key to connecting all production links. Through an efficient conveying device, it can ensure that the circuit boards move stably and quickly on the production line, thereby improving production efficiency and reducing production costs. At the same time, a good conveying device can also reduce the wear and damage of the circuit boards during conveying and ensure product quality.

[0003] Patent No. CN 214826889 U discloses a printed circuit board conveying device. Under the action of the gravity of the printed board, slider one slides downward and the spring is compressed downward, thereby absorbing the impact force generated when the circuit board falls onto the upper surface of the carrier plate, playing a buffering and protecting role for the circuit board, and ensuring that the circuit board will not be damaged during the process of falling vertically onto the upper surface of the carrier plate. By fixing rubber pads on both the upper surface of the carrier plate and the rear side of the buffer plate, this can further enhance the buffering and protecting effect on the circuit board in the horizontal and vertical directions.

[0004] However, in use, it has the following defects:

[0005] Although a buffer plate is used to buffer the circuit board in the horizontal direction, during the forward sliding process of the buffer plate, the electronic components on its surface may be damaged due to friction, and may shift under the action of inertia, affecting normal processing. Summary of the Utility Model

[0006] The purpose of this application is to provide a circuit board printing and conveying device, which solves the problems that in the process of the buffer plate sliding forward, the electronic components on its surface may be damaged due to friction, and after the circuit board reaches the processing position, it may shift under the action of inertia, affecting normal processing as mentioned in the background art.

[0007] To achieve the above object, the present application provides the following technical solution: A circuit board printing and conveying device, including a bottom block, a fixing frame, a placement plate and a threaded rod. Side grooves are penetrated through the front and rear side walls of the fixing frame. A slide rod is fixedly connected between the left and right inner side walls of the side groove. A side slider is slidably connected to the surface of the slide rod. The front and rear ends of the placement plate are respectively fixedly connected to the side walls of the front and rear side sliders. A limiting groove is horizontally opened at the center of the top end of the placement plate; A top groove is opened at the center of the top end of the fixing frame. The left and right sides inside the top groove are both slidably connected with top sliders. A second shock absorber is fixedly connected between the side wall of the top slider and the inner side wall close to the edge of the fixing frame. The top end of the top slider is fixedly connected with a support plate. Screws are horizontally threadedly connected to both side surfaces of the support plate. One end of the screw penetrates through the support plate and is threadedly connected to a limiting plate through a bearing. The bottom protrusion of the limiting plate is slidably connected horizontally inside the limiting groove.

[0008] In this technical solution, after the fixing frame reaches the processing position, it stops. At this time, the placement plate and the circuit board will continue to move forward under the action of inertia, thereby pushing the top slider to slide in the top groove. The second shock absorber can absorb and buffer the extrusion of the top slider, and then push the top slider and the placement plate back to their original positions. During this process, the side slider will also slide horizontally on the slide rod, thus ensuring the stability of the placement plate and improving the protection effect on the circuit board; Rotate the screw to drive the limiting plate to move towards the center of the placement plate, restricting and constraining the circuit board from both sides, so that the circuit board can move and reset synchronously with the placement plate, avoiding damage caused by the circuit board sliding alone, and can adapt to circuit boards of different sizes, improving the practicability of the device.

[0009] As an alternative solution to the technical solution of the present application, a buffer groove is opened at the top end of the bottom block. A support block is slidably connected up and down inside the buffer groove. A number of first shock absorbers are fixedly connected between the bottom of the support block and the inner bottom of the buffer groove.

[0010] As an alternative solution to the technical solution of the present application, both ends of the threaded rod are respectively threadedly connected to the surfaces of the mounting blocks on both sides. Two limiting rods are fixedly connected between the mounting blocks on both sides of the threaded rod. The limiting rods are located at the horizontal position of the threaded rod and on the front and rear sides of the threaded rod. The threaded rod and the limiting rods both penetrate through the side wall of the bottom block below the buffer groove, and the threaded rod is threadedly connected to the bottom block.

[0011] As an alternative solution to the technical solution of the present application, a servo motor is fixedly connected to the outer side wall of the mounting block at the horizontal position of the threaded rod. The outer end of the transmission shaft of the servo motor is fixedly connected to one end of the threaded rod.

[0012] As an alternative solution of the technical solution of the present application, the top surface of the top slider is located on the same horizontal plane as the top surface of the placement plate, and the bottom surface of the limiting plate is attached to the surface of the placement plate.

[0013] As an alternative solution of the technical solution of the present application, the left and right side surfaces of the placement plate are respectively fixedly connected to the side walls of the left and right top sliders.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] 1. Through the top groove, side groove, sliding rod, top slider and side slider, the present application can buffer the inertia of the circuit board. After the fixing frame reaches the processing position and stops, at this time, the placement plate and the circuit board will continue to move forward under the action of inertia, thereby pushing the top slider to slide in the top groove. The second shock absorber can absorb and buffer the extrusion of the top slider, and then push the top slider and the placement plate back to their original positions. During this process, the side slider will also slide horizontally on the sliding rod, thus ensuring the stability of the placement plate, thereby improving the protection effect on the circuit board.

[0016] 2. Through the support plate, screw rod, limiting plate and limiting groove, the present application can keep the circuit board and the placement plate synchronized. Rotate the screw rod to drive the limiting plate to move towards the center of the placement plate, restricting and constraining the circuit board from both sides, so that the circuit board can move and reset synchronously with the placement plate, avoiding damage caused by the circuit board sliding alone, keeping it in place, and being able to adapt to circuit boards of different sizes, improving the practicality of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the following will further elaborate in combination with specific embodiments.

[0022] A circuit board printing and conveying device, as shown in Figures 1 to 2 , includes a bottom block 1, a fixing frame 4, a placing plate 7 and a threaded rod 15. Side grooves 5 are penetrated and opened on the front and rear side walls of the fixing frame 4. A sliding rod 6 is fixedly connected between the left and right inner side walls of the side groove 5. A side slider 601 is slidably connected to the surface of the sliding rod 6. The front and rear ends of the placing plate 7 are respectively fixedly connected to the side walls of the front and rear side sliders 601. A limiting groove 14 is horizontally opened at the center of the top end of the placing plate 7. A top groove 8 is opened at the center of the top end of the fixing frame 4. The left and right sides inside the top groove 8 are both slidably connected with top sliders 10. A second shock absorber 9 is fixedly connected between the side wall of the top slider 10 and the inner side wall of the top groove 8 close to the edge of the fixing frame 4. The top end of the top slider 10 is fixedly connected with a support plate 11. Screws 12 are horizontally threadedly connected to both side surfaces of the support plate 11. One end of the screw 12 penetrates through the support plate 11 and is threadedly connected to a limiting plate 13 through a bearing. The bottom protrusion of the limiting plate 13 is slidably connected horizontally inside the limiting groove 14. The placing plate 7 and the circuit board push the top slider 10 to slide in the top groove 8 under the action of inertia. The second shock absorber 9 can absorb and buffer the extrusion of the top slider 10, and then push the top slider 10 and the placing plate 7 back to their original positions. During this process, the side slider 601 will also slide horizontally on the sliding rod 6, thus ensuring the stability of the placing plate 7. The screw 12 drives the limiting plate 13 to move towards the center of the placing plate 7, restricting the circuit board from both sides, so that the circuit board can move and reset synchronously with the placing plate 7, avoiding damage caused by the independent sliding of the circuit board and improving the protection effect.

[0023] Specifically, as shown in Figure 2 , a buffer groove 101 is opened at the top end of the bottom block 1. A support block 3 is slidably connected up and down inside the buffer groove 101. A number of first shock absorbers 2 are fixedly connected between the bottom of the support block 3 and the inner bottom of the buffer groove 101. The support block 3 moves up and down in the buffer groove 101 under the action of the first shock absorbers 2, thereby buffering the vibration from the up and down directions and improving the protection effect on the circuit board.

[0024] It should be noted that, as shown in Figure 1 and Figure 2As shown in the figure, both ends of the threaded rod 15 are threadedly connected to the surfaces of the mounting blocks 17 on both sides. And two limiting rods 16 are fixedly connected between the mounting blocks 17 on both sides of the threaded rod 15. The limiting rods 16 are located at the horizontal position of the threaded rod 15 and on the front and back sides of the threaded rod 15. Both the threaded rod 15 and the limiting rods 16 penetrate through the side wall of the bottom block 1 below the buffer groove 101, and the threaded rod 15 is threadedly connected to the bottom block 1. The limiting rods 16 can keep the bottom block 1 stable when the threaded rod 15 rotates to drive the bottom block 1 to move. And the lengths of the threaded rod 15 and the limiting rods 16 are determined according to the on-site processing requirements.

[0025] It should be noted that, as Figure 2 shown, a servo motor 18 is fixedly connected to the outer side wall of the mounting block 17 at the horizontal position of the threaded rod 15. The outer end of the transmission shaft of the servo motor 18 is fixedly connected to one end of the threaded rod 15. After the servo motor 18 is started, it drives the threaded rod 15 to rotate, so that the bottom block 1 moves horizontally on the surface of the threaded rod 15.

[0026] It should be noted that, as Figure 2 shown, the top surface of the top slider 10 is on the same horizontal plane as the top surface of the placement plate 7, and the bottom surface of the limiting plate 13 is in contact with the surface of the placement plate 7, so as to ensure that the limiting plate 13 can clamp and limit circuit boards of different thicknesses.

[0027] It should be noted that, as Figure 2 shown, the left and right side surfaces of the placement plate 7 are respectively fixedly connected to the side walls of the left and right top sliders 10, so as to ensure that the top sliders 10 can push the placement plate 7 back to its original position when resetting.

[0028] During actual use, the circuit board is placed on the placement board 7. The servo motor 18 starts to rotate the moving threaded rod 15, causing the bottom block 1 with the fixed frame 4 on it to move horizontally, thereby transporting and processing the circuit board. Through the top groove 8, side groove 5, sliding rod 6, top sliding block 10 and side sliding block 601, the inertia of the circuit board can be buffered. After the fixed frame 4 reaches the processing position, it stops. At this time, the placement board 7 and the circuit board will continue to move forward under the action of inertia, thus pushing the top sliding block 10 to slide in the top groove 8. The second shock absorber 9 can absorb and buffer the extrusion of the top sliding block 10, and then push the top sliding block 10 and the placement board 7 back to their original positions. During this process, the side sliding block 601 will also slide horizontally on the sliding rod 6, thereby ensuring the stability of the placement board 7, improving the protection effect on the circuit board. At the same time, through the support plate 11, screw rod 12, limit plate 13 and limit groove 14, the circuit board and the placement board 7 can be kept in synchronization. Rotating the screw rod 12 drives the limit plate 13 to move towards the center of the placement board 7, restricting and constraining the circuit board from both sides, so that the circuit board can move and reset synchronously with the placement board 7, avoiding damage caused by the circuit board sliding alone, and can adapt to circuit boards of different sizes, improving the practicability of the device.
