[0002] SMT stands for surface mount technology. In the field of electronics manufacturing, the development of SMT has continuously increased the performance requirements of placement machines. As electronic products develop towards miniaturization, high integration and high performance, the requirements for the accuracy and quality of electronic component placement are becoming increasingly stringent.

[0003] After searching, the Chinese patent announcement number is: CN218868450U, which discloses an SMT placement machine, including a chassis, hinges fixedly connected to both sides of the front of the chassis, and a chassis door installed on one side of the hinge, a base fixedly connected to the bottom of the chassis, a workbench welded to the inner wall of the chassis, and a limit assembly set on the top of the workbench, a manual wheel connected to one side of the workbench, a lifting mechanism installed on the inner wall of the chassis, and a placement mechanism fixedly connected to the bottom of the lifting mechanism. The SMT placement machine is provided with a manual wheel, a screw, a first moving block, a first clamping plate, a second moving block, a second clamping plate, a spring and a limit plate. The screw is rotated by rotating the manual wheel. Because the threads on both sides of the screw rotate in opposite directions, the first clamping plate and the second clamping plate clamp and limit the circuit board. The spring on the first clamping plate can buffer the clamping pressure to a certain extent to prevent excessive pressure from damaging the circuit board, thereby achieving a buffering and limiting effect on the circuit board. However, before the patch is placed, a lot of dust will remain on the PCB board, which will affect the processing effect when it reaches the body for patch placement. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides an SMT placement machine, which aims to improve the problem in the prior art that dust remains on the PCB board and affects the processing effect when it reaches the machine body for placement.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 3, the utility model provides an embodiment: an SMT patch machine, including a body 1, a feed port 3 is opened on the right side of the body 1, a connector 4 is fixedly connected to the inner top of the feed port 3, a blower 5 is fixedly connected to the left side of the bottom of the connector 4, a fixed plate 6 is fixedly connected to the right side of the bottom of the connector 4, an electrostatic adsorption strip 7 is fixedly connected to the inner side of the fixed plate 6, a workbench 8 is fixedly connected to the inside of the body 1, a patch board 9 is arranged on the right side of the top of the workbench 8, and the top of the patch board 9 is arranged at the bottom of the connector 4.

[0040] Specifically, by opening a feed port 3 on the body 1 and arranging a blower 5, dust and impurities on the surface of the patch board 9 entering from the feed port 3 can be cleaned to ensure that the patch surface is clean, thereby improving the bonding and stability of the electronic components and the patch board 9, ensuring the quality of the patch, and adsorbing static electricity in the patch board 9 and the surrounding environment through the electrostatic adsorption strip 7 to prevent damage caused by static electricity, further improving the quality and reliability of the patch, and conveniently storing the circuit board workpiece to be mounted through the loading position 11. The loader 13 can quickly transfer the SMT parts to the top of the workbench 8 to fit with the patch board 9. The degree of automation is high, which greatly shortens the patch time and improves work efficiency.

[0041] Refer to the attached Figure 4 The clamping mechanism 2 includes two slide rails 201, the outer walls of the two slide rails 201 are slidably connected to the sliders 202, the adjacent sides of the two sliders 202 are fixedly connected to the telescopic rods 203, the adjacent sides of the two telescopic rods 203 are fixedly connected to the clamping blocks 204, and the adjacent sides of the two clamping blocks 204 are fixedly connected to the gaskets 205, which prevent the clamping blocks 204 from scratching the patch board 9. The outer wall of the patch board 9 is arranged on the adjacent side of the two gaskets 205;

[0042] Specifically, through the sliding of the slider 202 on the slide rail 201 and the cooperation of the telescopic rod 203 and the clamping block 204, the patch board 9 can be tightly clamped and stably moved on the workbench 8. The setting of the gasket 205 further increases the stability of the clamping, avoiding the patch board 9 from being scratched by the clamping block 204. The telescopic rod 203 can be retracted to leave space for larger patch boards 9, avoiding the squeezing of the patch board 9 by the clamping block 204, so that it can adapt to patch boards 9 of different sizes, thereby improving the versatility and flexibility of the patch machine.

[0043] Refer to the attached Figure 1 and attached Figure 5 The outer wall of the loading position 11 of the body 1 is provided with an observation window 12, which is convenient for observing the situation inside the loading position 11.

The pads 15 can play a role in shock absorption and anti-slip. The maintenance door 16 on the rear side of the body 1 provides convenience for the repair and maintenance of the placement machine.

[0045] Working principle: The loading position 11 at the top of the machine body 1 is used to store the circuit board workpiece to be mounted. When the patch needs to be mounted, first, the patch board 9 to be mounted is fed in from the feed port 3 on the right side of the machine body 1. When the patch board 9 enters the feed port 3, the controller 18 starts the blower 5 on the left side of the bottom of the connector 4 to start working, blowing out a strong air flow to clean the surface of the patch board 9. At the same time, the electrostatic adsorption strip 7 adsorbs the static electricity on the patch board 9 or the surrounding environment. Then the patch board 9 reaches the bottom of the loading position 11, and the loader 13 loads the board. The SMT parts in position 11 are transferred to the top of the workbench 8 and fitted with the patch board 9 to complete the patch work. The two slide rails 201 are fixed to the bottom of the workbench 8 to provide a stable track for the movement of the slider 202. Through the connection of the slider 202, the telescopic rod 203 and the clamping block 204, the two clamping blocks 204 can tightly clamp the patch board 9 and move it. When the size of the patch board 9 is large, the two telescopic rods 203 can be retracted to leave space for the larger patch board 9 to avoid the clamping block 204 from squeezing the patch board 9.
