[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5. This power module manufacturing double-sided chip mounter provides a technical solution:

[0025] The first embodiment includes an outer housing 1 and multiple surface mount components 2. The outer housing 1 is provided with a moving mechanism 3, and multiple surface mount platforms 4 are mounted on the moving mechanism 3. The top of the surface mount platform 4 is provided with a clamping component 5 for clamping the circuit board to be mounted. The moving mechanism 3 is used to drive the surface mount platform 4 to move in the X-axis and Y-axis directions. A cleaning mechanism is provided above the surface mount platform 4. The cleaning mechanism includes a cleaning component 6, a driving component 8 and an air supply component 9.

[0026] The cleaning component 6 includes a slide rail 61, a movable frame 62 slidably connected to the surface of the slide rail 61, a rotating rod 63 rotatably connected inside the movable frame 62, and an air pipe 64 fixedly connected to one end of the rotating rod 63. Multiple nozzles 65 are fixedly connected at equal intervals at the bottom of the air pipe 64. The driving component 8 is used to drive the movable frame 62 to move back and forth. The air supply component 9 supplies air to the air pipe 64 and sprays it out through the nozzles 65, cleaning the surface of the circuit board under the back and forth movement. An angle limiting component 7 is provided on the rotating rod 63, and the angle limiting component 7 is used to limit the angle of the nozzles 65 after adjustment.

[0027] The drive assembly 8 includes a drive motor 81, which is fixedly connected to the back of the moving frame 62. The output end of the drive motor 81 is fixedly connected to a drive gear 82, and the back of the placement stage 4 is fixedly connected to a rack 83. The drive gear 82 and the rack 83 mesh and transmit power.

[0028] The gas supply assembly 9 includes a gas supply component 91, which is fixed to the back of the outer casing 1. The gas outlet of the gas supply component 91 is connected to a hose 92, and the gas outlet of the hose 92 is connected to the air pipe 64.

[0029] Before mounting the circuit board, the surface of the circuit board is cleaned by the cleaning component 6. During cleaning, air is supplied to the air pipe in the cleaning component 6 through the air supply component 9 and sprayed out, thereby removing dust from the surface of the circuit board by blowing air, ensuring the quality of mounting.

[0030] The second embodiment differs from the first embodiment in that: the angle limiting component 7 includes a limiting wheel 71, which is fixedly connected to the surface of the rotating rod 63. The limiting wheel 71 consists of a disc portion and multiple limiting teeth, which are fixed at equal intervals on the surface of the disc. A support plate 72 is fixedly connected to the moving frame 62. A limiting rod 73 is slidably connected inside the support plate 72. One end of the limiting rod 73 is located in the gap between the multiple limiting teeth. A limiting spring 74 is sleeved on the surface of the limiting rod 73 below the support plate 72. One end of the limiting spring 74 is fixedly connected to the bottom of the support plate 72, and the other end of the limiting spring 74 is fixedly connected to the limiting rod 73.

[0031] The nozzle 65 angle of the air supply assembly 6 can be adjusted, and the nozzle 65 angle is limited by the angle limiting assembly 7 when adjusting the nozzle 65 angle. After the angle is adjusted, the dust can be blown away, thereby improving the convenience of the device when using it.

[0032] In use, the circuit board is placed on the mounting table 4 and the clamping assembly 5 is activated for clamping. After clamping, the drive motor 81 is activated to rotate the drive gear 82, and with the cooperation of the rack 83, the moving frame 62 moves back and forth. The movement of the moving frame 62 drives the air pipe 64 to move, and the movement of the air pipe 64 drives the nozzle 65 to move. At the same time, the air supply component 91 is activated, and the air enters the air pipe 64 through the hose 92 and is sprayed out through the nozzle 65, thereby cleaning the surface of the circuit board by reciprocating airflow. In addition, the angle of the nozzle 65 is adjusted so that the dust can be blown away better. Rotating the rotating rod 63 changes the angle of the nozzle 65. While rotating the rotating rod 63, it drives the limiting wheel 71 to rotate. The rotating wheel 71 pushes the limiting rod 73 to move downward. After the limiting wheel 71 stops rotating, under the action of the limiting spring 74, the end of the limiting rod 73 enters the gap between the limiting teeth, thereby limiting the limiting wheel 71 and limiting the adjusted angle of the nozzle 65.
