DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 A glue dispensing device in this embodiment includes a base 1 and a shell 2. A turntable 3 and a glue dispensing robot arm 5 are arranged on the top of the base 1, and a gas processing mechanism 4 is arranged on the top of the shell 2.

[0023] The glue dispensing robot arm 5 can accurately move the glue dispensing head according to the pre-set path and position data, so that the glue is accurately applied on the circuit board.

[0024] A controller is disposed on the front side of the base 1 , and the controller can set the path and position data of the dispensing robot 5 , and can also start the motor 6 and the fan 401 through the controller.

[0025] The gas processing mechanism 4 includes a fan 401, which is fixedly installed on the inner bottom wall of the shell 2, and a filter box 402 is fixedly installed on the top of the shell 2. A connecting port 403 is provided between the fan 401 and the bottom of the filter box 402, and an exhaust port 404 is provided on the top of the filter box 402. A filter screen 405 and an activated carbon plate 406 located on the top of the filter screen 405 are movably installed inside the filter box 402.

[0026] The air inlet of the fan 401 is located above the turntable 3, and the air outlet of the fan 401 is located at the bottom of the connecting port 403. Through the fan 401, the volatilized gas during dispensing can be introduced into the interior of the filter box 402 through the connecting port 403 for treatment.

[0027] Since the filter box 402 is provided with a filter 405 and an activated carbon plate 406 inside, when the introduced gas enters the filter box 402, the filter 405 first filters the impurities in the gas, and then the activated carbon plate 406 adsorbs the tiny particles and harmful chemicals in the gas to further purify the gas. The double filtering mechanism is adopted, so that the dispensing device can significantly reduce the possible adverse effects on the environment and human body.

[0028] The filter 405 and the activated carbon plate 406 are both fixedly installed with handles on the front side, and the filter 405 and the activated carbon plate 406 are plug-in connected, so when replacing the filter 405 and the activated carbon plate 406, you only need to pull the filter 405 and the activated carbon plate 406 out of the filter box 402 through the handle, which is convenient for maintenance.

[0029] Four circuit board placement areas 301 are arranged on the top of the rotating disk 3 , and positioning members 302 are arranged inside the four circuit board placement areas 301 .

[0030] When dispensing glue, four circuit boards can be placed on the turntable 3 at the same time, and the circuit boards can be fixed by the positioning members 302 to ensure the stability of the circuit boards when placed on the turntable 3, thereby improving the precision of dispensing glue.

[0031] The four positioning members 302 each include a groove 31. Two grooves 31 are provided at the bottom of the four circuit board placement areas 301. A slider 32 is slidably installed inside each of the two grooves 31. A spring 33 is fixedly installed between the inner wall of each groove 31 and the side wall of the slider 32. A positioning plate 34 is fixedly installed on the top of each slider 32.

[0032] Through the cooperation of the slider 32 and the spring 33 , the position of the positioning plate 34 can be stably moved left and right, thereby fixing the circuit board.

[0033] A motor 6 is fixedly installed on the inner bottom wall of the cavity, and the output shaft of the motor 6 is fixedly connected to the bottom center of the turntable 3. Under the action of the motor 6, the turntable 3 can be rotated to rotate the next circuit board to the dispensing head of the dispensing robot arm 5 for continuous dispensing work.

[0034] When implementing, follow these steps:

[0035] 1) First, four circuit boards are placed in four circuit board placement areas 301, and the four circuit boards are fixed by the positioning members 302. First, the two positioning plates 34 are pulled outward, and the two positioning plates 34 drive the bottom slider 32 to slide in the groove 31 and compress the spring 33. At this time, the circuit board is placed in the circuit board placement area 301, and the positioning plates 34 are released. The elastic force of the spring 33 is released so that the circuit board is fixed between the two positioning plates 34;

[0036] 2) Then, the dispensing path of the dispensing robot arm 5 is set by the controller so that the dispensing head of the dispensing robot arm 5 is located above one of the circuit boards to perform the dispensing work;

[0037] 3) When dispensing glue on the next circuit board, the motor 6 drives the turntable 3 to rotate, and the next circuit board is moved to the bottom of the dispensing robot arm 5. This process is repeated, and four circuit boards can be dispensed glue continuously.

[0038] 4) When the dispensing work starts, the fan 401 is started. The fan 401 introduces the gas generated during the dispensing into the filter box 402 through the connecting port 403. After being filtered by the filter screen 405 and the activated carbon plate 406, the gas is discharged from the exhaust port 404.

[0039] In summary, the dispensing device, by setting up a gas processing mechanism 4, the fan 401 introduces volatile gases into the filter box 402, the filter box 402 filters out harmful components, and the purified gas is released into the environment through the exhaust port 404, thereby avoiding direct discharge of gas generated by dispensing, reducing environmental pollution, and protecting the air quality of the working environment.
