It is a device that accurately places surface mount components on the PCB pads by moving the placement head.

[0003] A search has revealed a Chinese patent publication numbered CN 213485269 U, which discloses a fully automatic intelligent patch machine. This utility model addresses the technical issues of limited placement, requiring individual patch cassette replacements, and lacking object fixation. The machine, comprised of a lifting transmission mechanism and a position-limiting control mechanism, allows for flexible adjustment of patch placement, facilitates rapid patching operations, and automatically replaces cassettes and secures patched objects, improving patch accuracy.

[0004] The smart placement machine in the above patent still has certain shortcomings. During the process of placement processing of PCB boards, there are extremely strict requirements for the cleanliness of the inside of the placement machine. If there is dust on the PCB board, it is easy for the components to directly press dust, fibers and other impurities on the board surface or holes of the PCB board, resulting in subsequent failures such as poor contact of the components. The existing side heat dissipation and ventilation equipment of the smart placement machine has poor filtering performance for dust in the air, which will cause dust in the air to enter the interior of the placement machine and fall on the PCB board surface, thereby affecting the service life and quality of the product. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an intelligent placement machine, which solves the problem that the existing side heat dissipation and ventilation equipment of the intelligent placement machine has poor dust filtering performance in the air, which causes dust in the air to enter the interior of the placement machine and fall on the PCB board, thereby affecting the service life and quality of the product.

[0012] Preferred technical solution four: the side ventilation duct is curved to facilitate air intake and dust prevention.

[0016] Compared with the existing technology, the present invention provides an intelligent placement machine with the following beneficial effects:

[0017] (1) The utility model provides a SMT machine ventilation component and a SMT machine heat dissipation component on the SMT machine main box. Before the external airflow enters the interior of the SMT machine main box, it will be filtered and adsorbed by the moisture adsorption cotton strips in the SMT machine ventilation component, and then the dust particles will be filtered again by the dust filter provided in the air inlet filter pipe, thereby greatly improving the interception of dust during the ventilation process of the SMT machine main box and avoiding the influence of dust on the operation of the SMT machine main box. The heat dissipation fan in the SMT machine heat dissipation component can actively exhaust the hot air generated inside the SMT machine main box, thereby avoiding damage to components caused by too slow heat dissipation from the heat dissipation port.

[0026] See also Figure 1-4 A smart placement machine includes a placement machine main box 1, a placement machine control box 2 is arranged on the side of the placement machine main box 1, a placement machine ventilation component 3 for dust-proof ventilation is arranged on the top of the placement machine main box 1, and a placement machine heat dissipation component 4 for heat dissipation is arranged on the top of the side of the placement machine main box 1.

[0027] The SMT machine ventilation assembly 3 includes a top vent 301 arranged at the top of the SMT machine main box 1, the top of the top vent 301 is connected to the air inlet filter tube 302, the top of the air inlet filter tube 302 is provided with a top closing cover 303, the bottom end of the top closing cover 303 is vertically provided with a middle connecting rod 304, the bottom end of the middle connecting rod 304 is provided with a dust filter 305, and the dust filter 305 is slidably inserted into the bottom of the air inlet filter tube 302.

[0028] Two side ventilation pipes 306 are symmetrically arranged on both sides of the air inlet filter pipe 302. One end of the side ventilation pipe 306 is open, and the other end of the side ventilation pipe 306 is connected to the air inlet filter pipe 302. A moisture absorption cotton strip 307 is arranged in the side ventilation pipe 306. Two inner cavity support blocks 308 are symmetrically arranged on both sides of the bottom end of the moisture absorption cotton strip 307. The inner cavity support block 308 is connected to the inner wall of the side ventilation pipe 306.

[0029] The heat dissipation assembly 4 of the placement machine includes a heat dissipation port 401 opened on the top side of the placement machine main box 1, a heat dissipation fan 402 is installed in the heat dissipation port 401, an external connecting tube 403 and a tube mouth closing plate 404 are provided on the outside of the heat dissipation port 401, a tube mouth filter 405 is provided in the middle of the tube mouth closing plate 404, both ends of the tube mouth closing plate 404 are inserted into the external connecting tube 403, and the outside of the external connecting tube 403 is fixedly connected to the tube mouth closing plate 404 and the external connecting tube 403 by an inserted fixing bolt 406.

[0030] Example 2: The difference between this example and Example 1 is that an external thread is provided on the outer side of the top end of the air inlet filter tube 302, and an internal thread is provided on the inner wall of the bottom end of the top closing cover 303, and the air inlet filter tube 302 and the top closing cover 303 are fixedly connected by threads.

[0031] This makes it more convenient for users to disassemble the dust filter 305 provided in the air inlet filter tube 302 .

[0032] Embodiment 3: The difference between this embodiment and embodiment 1 is that the side ventilation pipe 306 is curved to facilitate air intake and dust prevention.

[0033] The dust in the air can be better blocked by the moisture adsorbing cotton strip 307.

[0034] Embodiment 4: The difference between this embodiment and embodiment 1 is that a support block is provided at the bottom end of the side ventilation pipe 306, and the support block is connected to the main box 1 of the placement machine.

[0035] The side ventilation pipes 306 are more stably arranged on both sides of the air inlet filter pipe 302.

[0036] In this embodiment, since the existing intelligent placement machine's side heat dissipation and ventilation equipment has poor dust filtering performance in the air, dust in the air will enter the placement machine and fall on the PCB board, thereby affecting the product's service life and quality.

[0037] In summary, in a specific implementation, by providing a SMT ventilation component 3 and a SMT heat dissipation component 4 at the ventilation and heat dissipation positions on the SMT main box 1 respectively, when ventilation is required in the SMT main box 1, air can enter the air inlet filter tube 302 through the side ventilation tube 306, and then enter the top vent 301 through the air inlet filter tube 302, and supply air to the interior of the SMT main box 1 through the top vent 301, thereby preventing the internal components of the SMT main box 1 from being damaged due to excessive operating temperature.

[0038] When the air passes through the side ventilation pipe 306, the moisture in the air is filtered and adsorbed by the moisture adsorption cotton strips 307 set in the side ventilation pipe 306, so that the water vapor in the air can be effectively removed. When the air enters the air inlet filter pipe 302, it will be filtered again by the dust filter 305 to filter out the polluted particles in the air, thereby preventing dust and moisture from entering the main box 1 of the placement machine and affecting the placement operation.

[0039] The SMT machine heat dissipation component 4 is arranged at the top end of the side of the SMT machine main box 1. The cooling fan 402 in the SMT machine heat dissipation component 4 can actively exhaust the hot air generated inside the SMT machine main box 1 when powered on, thereby preventing the heat dissipation port 401 from dissipating heat too slowly and causing damage to components. The barrel filter 405 arranged on the side of the cooling fan 402 can effectively block dust in the air and prevent dust from entering the interior of the SMT machine main box 1, which will not affect the SMT processing on the PCB board.
