Description
An automatic feeding device for an SMT printing machine Technical Field
[0001] This utility model relates to the technical field of automatic feeding equipment for SMT printing machines, specifically to an automatic feeding device for an SMT printing machine. Background Technology
[0002] SMT printing machines, also known as solder paste printing machines, generally consist of mechanisms for mounting the circuit board, applying solder paste, imprinting, and conveying the circuit board. Patent CN202121553136.7 discloses an automatic feeding device for an SMT printing machine. This device vertically places the circuit boards to be printed inside a material tray, with the circuit boards partially outside the tray. Adjacent circuit boards are separated by dividers. A picking mechanism then places the circuit boards from the tray onto a conveyor belt. After picking up one circuit board, the tray slides, allowing the next circuit board to reach its designated position for easy retrieval by the picking mechanism. This achieves automatic feeding for the SMT printing machine, improving its feeding efficiency. However, because the material tray is not easily disassembled, the circuit boards still need to be manually inserted one by one after being picked up, which is inconvenient. Therefore, we propose an automatic feeding device for an SMT printing machine. Summary of the Invention
[0003] To address the problems in the existing technology, this utility model provides an automatic feeding device for an SMT printing machine.
[0004] The technical solution adopted by this utility model to solve its technical problem is an automatic feeding device for an SMT printing machine, including a machine base. The top surface of the machine base is provided with an adjustment groove, and an adjustment screw is rotatably installed in the groove. A slide seat is slidably installed in the groove and screwed to the screw, and there are two sets of slide seats. A reducer that is driven by the screw is bolted to the outer wall surface of the machine base, and a servo motor is installed at the power input end of the reducer.
[0005] The top surface of the slide block is bolted with a tray that fits the machine base, and the top surface of the tray block is integrally constructed with a locking block for limiting the position. There are multiple sets of locking blocks, and the top surface of the tray block is provided with a material frame that fits the locking block.
[0006] By adopting the above technical solution, during the use of the automatic feeding equipment for SMT printing machines, the servo motor on the outside of the machine can operate and drive the lead screw on the inside of the slide to rotate under the operation of the reducer. This causes the two sets of slide blocks that are slidably connected on the inside of the slide block to be synchronously screwed together with the lead screw and slide in the slide block under the screwing force. Then, the position of the two sets of slide blocks can be easily adjusted according to the needs of use, and the position between the material frame on the slide block surface and the robot arm can be easily adjusted according to the needs of use. This allows for continuous feeding of the robot arm and convenient feeding of the SMT printing machine.
[0007] During the use of the material frame for holding circuit boards, the material frame can directly engage with the tray on the surface of the slide. Under the limiting action of multiple sets of locking blocks, the material frame can be stably placed on the surface of the tray and can change position as the tray moves. At the same time, the material frame is easy to disassemble, making it convenient to directly disassemble the material frame and replace it with a material frame full of circuit boards after the automatic feeding of circuit boards inside the material frame is completed.
[0008] Specifically, pull holes are provided on both sides of the outer periphery of the material frame, and there are multiple sets of pull holes.
[0009] By adopting the above technical solution, the perforation makes it easier to assemble and disassemble the material frame.
[0010] Specifically, a protective rubber pad is adhered to the top surface of the tray.
[0011] By adopting the above technical solution, the rubber pad has good elasticity, which helps to reduce the scratches caused by friction between the pallet and the material frame.
[0012] Specifically, the pallet and the material frame are each equipped with magnetic blocks that are magnetically connected to each other, and there are multiple sets of magnetic blocks.
[0013] By adopting the above technical solution, the magnetic blocks between the pallet and the material frame can be magnetically connected to each other, which facilitates the improvement of the stability of the material frame when it is placed on the surface of the pallet.
[0014] Specifically, the top surface of the machine tool is provided with grooves, and there are multiple sets of grooves. The bottom surface of the tray is integrally constructed with convex strips that fit the grooves, and there are multiple sets of convex strips.
[0015] By adopting the above technical solution, the convex strip and the groove fit together, which helps to improve the stability of the pallet when sliding on the machine surface, so that the pallet can support the material frame more stably.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The technical solution of this application, through the design of a chute, lead screw, slide block, reducer, servo motor, and material frame, enables the servo motor on the outside of the machine to operate and drive the lead screw on the inside of the chute to rotate under the operation of the reducer. This allows the two sets of slide blocks, which are slidably connected on the inside of the chute, to synchronously screw together with the lead screw and slide within the chute under the screwing force. This allows for easy adjustment of the positions of the two sets of slide blocks according to usage requirements, and also facilitates the adjustment of the position between the material frame on the slide block surface and the robot arm. This allows for easy switching according to usage requirements, thereby continuously feeding the robot arm and facilitating feeding the SMT printer.
[0018] 2. The technical solution of this application, through the design of the tray and the locking block, allows the material frame containing the circuit boards to be directly engaged with the tray on the surface of the slide during use. Under the limiting action of multiple sets of locking blocks, the material frame can be stably placed on the surface of the tray and can change position as the tray moves. At the same time, the material frame is easy to disassemble, making it convenient to directly disassemble the material frame and replace it with a material frame full of circuit boards after the automatic feeding of the circuit boards inside the material frame is completed, thereby improving the feeding efficiency.

[0026] During use, the servo motor 6 on the outside of the machine 1 operates and drives the lead screw 3 on the inside of the slide 2 to rotate under the operation of the reducer 5. This causes the two sets of slide blocks 4, which are slidably connected on the inside of the slide 2, to be synchronously screwed together with the lead screw 3 and slide in the slide 2 under the force of the screwing. The position of the two sets of slide blocks 4 can be easily adjusted according to the needs of use, and the position between the material frame 9 on the surface of the slide block 4 and the robot arm can be easily switched according to the needs of use, so as to continuously feed the robot arm and facilitate the feeding of the SMT printer.

[0030] As shown in Figures 1 and 2, a protective rubber pad 12 is adhered to the top surface of the tray 7.
[0031] When in use, the rubber pad 12 has good elasticity, which helps to reduce the scratches caused by friction between the pallet 7 and the material frame 9.
[0032] As shown in Figures 1 and 2, the pallet 7 and the material frame 9 are each equipped with magnetic blocks 11 that are magnetically connected to each other, and there are multiple sets of magnetic blocks 11.
