Description

TECHNICAL FIELD

[0001] The present application relates to the field of circuit board production, in particular to a motor control circuit board production and transportation pushing device. BACKGROUND

[0002] The circuit board generally refers to a flat board used for assembling electronic components, and the circuit board has many lines and components, which can be connected to realize the function of electronic components. In the current circuit board production factory, the circuit board is usually stacked in the SMT loading and unloading frame. Since the SMT loading and unloading frame is acid and alkali resistant, oil stain resistant, high temperature resistant, non-toxic and odorless, and easy to clean, the circuit board is stacked in the SMT loading and unloading frame, which can facilitate the transportation, distribution, storage, circulation processing and other links.

[0003] At present, there are two ways to place the circuit board on the SMT loading and unloading frame. One is to manually insert the PCB into the partition layer of the SMT loading and unloading frame by hand, but this way is high in labor cost and low in work efficiency, and is not suitable for factory mass production. The second is to use the circuit board loading machine on the market, which first transports the SMT loading and unloading frame to a high place, and then inserts the PCB into the SMT loading and unloading frame by the equipment, and slowly lowers the SMT loading and unloading frame until it is full. But this way needs to repeatedly lift and lower the SMT loading and unloading frame, which increases the energy consumption of the loading process and increases the production cost. The SMT loading and unloading frame is made of metal, and there is a safety hazard in the process of lifting it. Repeatedly lifting and lowering it will cause the equipment to be worn out, resulting in unstable fixation, which may cause it to directly fall from a high place and cause a safety accident. SUMMARY

[0031] As shown in Figure 1 , Figure 3 and Figure 4 , the mounting seat 11 is provided with the driving mechanism 3 which can make the two feeding conveyor belt 21 self operation, the driving mechanism 3 includes the servo motor 31 for providing power for the operation of feeding conveyor belt 21, the output shaft of servo motor 31 is connected with the rotating shaft of the left feeding conveyor belt 21 through the transmission belt, after starting the servo motor 31, the left feeding conveyor belt 21 will rotate synchronously through the transmission belt and the output shaft of servo motor 31; the pulley I 32 is arranged on the rotating shaft of the feeding conveyor belt 21 at the top, which can rotate with the rotating shaft of the feeding conveyor belt 21; the guide rail 34 is arranged vertically on the mounting seat 11; and the pulley II 33 can slide on the guide rail 34, the transmission belt is wound between the two pulley I 32 and pulley II 33, which can make the two pulley I 32 and pulley II 33 rotate at the same time, and the right pulley I 32 and the feeding conveyor belt 21 connected with it are provided with a gear box, under the action of the gear box, the operation direction of the two feeding conveyor belt 21 is opposite.

[0032] As shown in Figure 1 and Figure 5As shown, the mounting base 11 is also provided with a distance adjusting mechanism 4 capable of adapting the two material conveying belts 21 to circuit boards of various sizes. The distance adjusting mechanism 4 includes a cylinder II 41 for pushing the material conveying belt 21 on the right, which can push the material conveying belt 21 on the right to slide on the mounting base 11 to change the distance between the two material conveying belts 21, so that circuit boards of different sizes can be clamped between the two material conveying belts 21; and a drive rod 42 for adjusting the position of the pulley II 33 on the guide rail 34. The drive rod 42 is rotatably connected with the material conveying belt 21 on the right and the pulley II 33. When the drive rod 42 slides with the material conveying belt 21, it drives the pulley II 33 to rise and fall on the guide rail 34, so that the transmission belt can be straightened between the pulley I 32 and the pulley II 33.

[0033] As shown in Figure 1 and Figure 6 , the top of the mounting base 11 is provided with a feeding mechanism 5. The feeding mechanism 5 includes a support groove frame 51 with an opening at the top for the passage of circuit boards; two mounting plates 52 symmetrically arranged on the material conveying belt 21 on the right and capable of moving synchronously therewith; the two mounting plates 52 are triangular and fixed by bolts, stable in structure; and a conveying belt 53 laid on the two mounting plates 52 for conveying and feeding circuit boards. The output end of the conveying belt 53 is located above the opening of the support groove frame 51.

[0034] As shown in Figure 1 , Figure 7 and Figure 8 , the support groove frame 51 is provided with a guide mechanism 6 for assisting the clamping of circuit boards between the two material conveying belts 21. The guide mechanism 6 includes a reciprocating cylinder 61 capable of rotating on the mounting plate 52 and having an inclined annular groove in the cylinder body; a protruding column 62 capable of being detached and replaced and slidingly fitted with the groove on the reciprocating cylinder 61. When the reciprocating cylinder 61 rotates, the protruding column 62 slides in the inclined annular groove. Due to the particularity of the inclined annular groove, the protruding column 62 presents a reciprocating motion in the horizontal direction with the mounting plate 52 as the reference; a guide roller frame 63 slidingly connected with the support groove frame 51 for guiding the placement of circuit boards, the guide roller frame 63 is arranged obliquely to the lower left and can reciprocate with the protruding column 62; a cogwheel 64 arranged on the output shaft of the conveying belt 53, which rotates synchronously with the output shaft of the conveying belt 53; and a full gear 65 arranged on the reciprocating cylinder 61 and meshing with the toothed part of the cogwheel 64. The rotation of the cogwheel 64 drives the rotation of the full gear 65, and the reciprocating cylinder 61 also rotates accordingly.

[0035] When the circuit board is inserted into the MT feeding and discharging frame, the worker needs to start the servo motor 31, and under the action of the pulley I 32, the pulley II 33 and the transmission belt, the two feeding conveyors 21 start to operate, and the feeding conveyor 21 on the right will rotate in the opposite direction under the action of the gear box, then the worker only needs to place the circuit board on the conveying belt 53, and use the conveying belt 53 to transport the circuit board to the guide roller frame 63, and then the circuit board is inserted into the partition on the feeding conveyor 21 on the left along the inclined roller, and when the conveying belt 53 is operating, the reciprocating cylinder 61 will rotate under the meshing action of the missing gear 64 and the full gear 65, so that the protruding column 62 moves horizontally, the guide roller frame 63 is pulled out, and the right end of the circuit board falls on the partition on the feeding conveyor 21 on the right, so that the partition between the two feeding conveyors 21 is filled, then the worker needs to start the cylinder I 22, and use the feeding plate 23 to push all the circuit boards into the SMT feeding and discharging frame placed on the conveying seat 12, so that the SMT feeding and discharging frame can be filled with circuit boards without the need to adjust the SMT feeding and discharging frame, and if the size of the circuit board changes, the worker can start the cylinder II 41 to move the feeding conveyor 21 on the right, so as to adjust the distance between the two feeding conveyors 21, and at the same time, the driving rod 42 drives the pulley II 33 to slide in the guide rail 34, so that the transmission belt between the pulley I 32 and the pulley II 33 is kept straight, and the worker needs to disassemble the original protruding column 62 and replace it with a protruding column 62 with appropriate length, so that the end part can continue to slide in the groove on the reciprocating cylinder 61, so that the device can be applied to circuit boards of different sizes. Example 2

[0036] On the basis of example I, in order to facilitate the input and output of the SMT feeding and discharging frame, as Figure 1 , Figure 9 and Figure 10As shown, the conveyor base 12 is equipped with a conveying mechanism 7 for transporting SMT loading and unloading racks. The conveying mechanism 7 includes a feeding roller frame 71 that can slide vertically on the conveyor base 12 to assist in the transport of the SMT loading and unloading racks. The feeding roller frame 71 initially slides down due to its own gravity and does not contact the SMT loading and unloading racks, thus preventing the SMT loading and unloading racks from shaking or shifting due to the rolling of the rollers on the feeding roller frame 71 when the circuit boards are pushed into the SMT loading and unloading racks; an electric push rod 72 that provides power for the sliding of the feeding roller frame 71; a lifting plate 73 located at the bottom of the feeding roller frame 71; and a slider 74 that can move synchronously with the output shaft of the electric push rod 72 and cooperates with the lifting plate 73. The front half of the bottom of the lifting plate 73 is flat. The rear half is set as an inclined surface. When the slider 74 slides along the inclined surface, it will lift the lifting plate 73 and the feeding roller frame 71. The thickness of the rear half of the lifting plate 73 is thicker than that of the front half, and the difference in thickness is equal to the maximum distance that the feeding roller frame 71 can slide on the conveyor seat 12. When the slider 74 moves to the rear end of the lifting plate 73, the feeding roller frame 71 is just lifted up to contact the SMT loading and unloading rack. The worker can easily transport the SMT loading and unloading rack after it is filled with circuit boards using the feeding roller frame 71.

[0037] like Figure 1 , Figure 11 and Figure 12 As shown, the conveyor base 12 is also equipped with a limiting mechanism 8 that can limit the placement position of the SMT loading and unloading rack. The limiting mechanism 8 includes a wedge-shaped rod 82 that is slidably disposed on the lifting plate 73, and a spring is provided between the wedge-shaped rod 82 and the lifting plate 73; a limiting rod 81 connected to the wedge-shaped rod 82 and slidingly extending out of the conveyor base 12, Two limiting rods 81 are symmetrically arranged on both sides of the wedge rod 82. The limiting rods 81 extending out of the conveyor seat 12 have a beveled surface on the side away from each other, while the side closer to each other is straight. A contact cylinder 83 is set on the slider 74 and can slide with the wedge rod 82. The end of the wedge rod 82 that engages with the contact cylinder 83 is inclined downward, and the downward height is equal to the height of the limiting rod 81 extending out of the conveyor seat 12. When an empty SMT loading / unloading rack is transported to the conveyor seat 12, the SMT loading / unloading rack will slide along the beveled surface of the limiting rod 81 extending out of the conveyor seat 12 and get stuck between the two limiting rods 81, making it unable to move, which facilitates the subsequent insertion of circuit boards. After the circuit board is loaded, the slider 74 slides and contacts the downward inclined end of the wedge rod 82, pressing down the wedge rod 82 and causing the limiting rod 81 to move downward at the same time, no longer obstructing the SMT loading / unloading rack, allowing it to be transported out smoothly.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
