[0022] Embodiment 1:

[0023] Combined with Figures 1-4As shown in the figure, an automatic chip mounter for a circuit board provided by the utility model includes a machine body 1. A support rod 103 and a fixing plate 104 are fixedly arranged on the machine body 1. A motor 2 is fixedly arranged on the fixing plate 104. A lead screw 201 is fixedly arranged at the output end of the motor 2. A jacking plate 203 is spirally arranged on the lead screw 201. A stabilizing rod 202 is slidably arranged on the jacking plate 203. A feeding plate 3 is slidably arranged on the support rod 103. A storage pipe 302 and a hydraulic cylinder 5 are fixedly arranged on the feeding plate 3. A feeding port 301 is formed on the feeding plate 3. An adjusting sleeve 303 is slidably arranged on the storage pipe 302. A spring 304 is fixedly arranged on the adjusting sleeve 303. A conveyor belt 4 is rotatably arranged below the adjusting sleeve 303. A placement groove 401 is formed on the conveyor belt 4. A receiving plate opening 101 and a limiting groove 102 are formed on the machine body 1. The receiving plate opening 101 is located on one side of the conveyor belt 4. The conveyor belt 4 is rotatably connected to the machine body 1. The width of the limiting groove 102 is equal to the width of the corresponding placement groove 401, and the depth of the limiting groove 102 is equal to the depth of the corresponding placement groove 401. The fixing plate 104 is fixedly connected to the support rod 103. The lead screw 201 is rotatably connected to the fixing plate 104. One end of the stabilizing rod 202 is fixedly connected to the fixing plate 104, and the other end of the stabilizing rod 202 is fixedly connected to the machine body 1. The jacking plate 203 is movably connected to the upper surface of the machine body 1. The storage pipe 302 is fixedly connected to the bottom of the feeding plate 3. The diameter of the storage pipe 302 is equal to the diameter of the feeding port 301. The adjusting sleeve 303 is slidably connected to the outer wall of the storage pipe 302. One end of the spring 304 is fixedly connected to the adjusting sleeve 303, and the other end of the spring 304 is fixedly connected to the bottom of the feeding plate 3. The storage pipe 302 is located in the middle of the spring 304. The side of the feeding plate 3 is fixedly connected to the telescopic end of the hydraulic cylinder 5. The fixed end of the hydraulic cylinder 5 is fixedly connected to the machine body 1. An electromagnetic valve is arranged in the adjusting sleeve 303. The adjusting sleeve 303 is located above the conveyor belt 4.

[0024] Specifically, a fixed plate 104 is fixedly welded on the support rod 103 of the machine body 1, and a motor 2 is fixedly installed on the fixed plate 104 to provide support for the motor 2. A lead screw 201 is provided at the output end of the motor 2 so that the motor 2 can control the rotation of the lead screw 201. A jacking plate 203 is helically connected to the lead screw 201, and the jacking plate 203 is slidably connected to two stabilizing rods 202. When the lead screw 201 drives the jacking plate 203 to rotate, it will be blocked by the stabilizing rods 202 and thus move up and down along the stabilizing rods 202. A feeding plate 3 is also slidably connected to the support rod 103. The feeding plate 3 is fixedly connected to the telescopic end of a hydraulic cylinder 5 so that the hydraulic cylinder 5 can control the feeding plate 3 to slide back and forth on the support rod 103. A feeding port 301 is formed on the feeding plate 3, and a storage pipe 302 is fixedly welded to the bottom of the feeding plate 3 so that the patches can be stored in the storage pipe 302. An adjusting sleeve 303 is slidably connected to the outer wall of the storage pipe 302. A spring 304 is fixedly welded to the adjusting sleeve 303, and the other end of the spring 304 is fixedly connected to the bottom of the feeding plate 3. The spring 304 surrounds the storage pipe 302 so that when the adjusting sleeve 303 slides on the storage pipe 302, it can compress the spring 304, and the spring 304 can also push the adjusting sleeve 303. An electromagnetic valve is installed in the adjusting sleeve 303 so that the staff can control the patches in the storage pipe 302 to fall. A conveyor belt 4 is also installed on the machine body 1. A placement groove 401 is formed on the conveyor belt 4. A limiting groove 102 is formed on the machine body 1. The depth and width of each limiting groove 102 and the corresponding placement groove 401 are equal so that different types of circuit boards can enter the placement groove 401 through the limiting groove 102 to complete classified placement. The adjusting sleeve 303 is located above the conveyor belt 4 so that the patches can be pasted on the circuit board. A board receiving opening 101 is formed on the machine body 1, and the board receiving opening 101 is located on one side of the conveyor belt 4. When the conveyor belt 4 rotates, the circuit boards that have completed pasting will fall from the board receiving opening 101 and thus be collected by the staff for convenient operation.

[0025] Working principle and usage process of the utility model: First, the hydraulic cylinder 5 is used to control the feeding plate 3 to slide backward on the support rod 103 so that each adjusting sleeve 303 is located on the upper surface of the lifting plate 203. At this time, different types of circuit boards are transported from the limiting groove 102 to their respective placing grooves 401 through the transport device. Subsequently, the motor 2 is started to control the rotation of the lead screw 201, causing the lifting plate 203 to rise. When the height of the lifting plate 203 is higher than the height of all circuit boards, the hydraulic cylinder 5 is started to control the feeding plate 3 to move forward, causing the adjusting sleeve 303 to leave the surface of the lifting plate 203. At this time, the adjusting sleeve 303 will be pushed downward due to the elasticity of the spring 304, so that each adjusting sleeve 303 contacts the corresponding circuit board, completing the chip mounting operation. As the conveyor belt 4 rotates, the circuit boards on the placing groove 401 will fall from the board receiving port 101 and thus be collected. Then, the lifting plate 203 is controlled to descend to a height lower than that of all adjusting sleeves 303, and the hydraulic cylinder 5 is used to control the adjusting sleeves 303 to reach the lifting plate 203. By repeating the above operations, the automatic chip mounting of multiple types of circuit boards can be completed.

[0026] It should be understood that the above specific embodiments of the present utility model are only used for illustrative explanation or interpretation of the principle of the present utility model, and do not constitute a limitation to the present utility model.
