Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to an automatic mold cleaning machine. Background Art

[0002] The current cleaning devices for precision packaging molds can be divided into two structures. One is to clamp the disassembled mold in the mechanism, and achieve the purpose of automatic cleaning by combining the rotation of the clamping mechanism with the cleaning mechanism. However, this is prone to splashing, especially splashing of the cleaning liquid, which can easily endanger the operator and damage other mechanisms in the equipment. In addition, taking out the mold for cleaning and maintenance not only consumes time and manpower, but also indirectly increases costs.

[0003] At the same time, this type of structure has the disadvantages of high site occupancy and inconvenient movement. Second, the dry ice cleaning mechanism is assembled in a closed box, and the dry ice particles are mixed with compressed gas and then sprayed out from the discharge port. The operator can perform cleaning work through an external air pipe and nozzle. Although this type of structure is equipped with casters for easy mobility, such manual cleaning has the disadvantages of low efficiency, unstable cleaning effect and non-fixed cleaning path. At the same time, due to the low temperature nature of dry ice, condensed water will be generated inside the equipment when the equipment is working due to the large temperature difference between the inside and the outside, but the two existing structures currently do not have components to deal with condensation.

[0004] The powdered dry ice cleaning machine disclosed in the existing utility model patent CN208680046U crushes the whole block of dry ice by pushing and cutting it, and combines it with a high-pressure gas source so that the high-pressure gas and the powdered dry ice are mixed in the mixing chamber and then sprayed out through the nozzle to achieve the purpose of cleaning. Although it can achieve the purpose of cleaning precision equipment, it is limited to manual operation by the operator, the cleaning route is not fixed, the cleaning effect is unstable, and it cannot be used in large-scale industrial production.

The condensed water is collected in the water receiving box 17 through a drain pipe 142. The water receiving box 17 is detachably arranged in the frame 1 for easy replacement. Figure 2 , Fig. 9Since the temperature of dry ice is -78.5℃, the temperature difference between the inside and outside of the equipment is large during operation, and condensation will occur inside the equipment. Therefore, a water tank 14 is provided below the dry ice crushing device 12 to store the generated condensed water. A drain pipe 142 is provided on the water tank 14, and the water discharged from the drain pipe 142 will fall into the water tank 17. The water tank 17 is replaceable, and the operator can replace the water tank 17 by opening the sheet metal double door 6. The water tank 14 is provided with a through hole through which the air pipe can pass. In order to prevent the outflow of water, an annular baffle 141 is provided around the through hole.

[0038] The PLC controller 29 is mainly electrically connected to various pneumatic components, the dry ice crushing device 12, the lifting device 3 and the robot control cabinet 15, and the robot control cabinet 15 is used to control the cleaning robot 8. When in use, the dry ice crushing device 12 and the cleaning robot can be controlled through the control panel 10 according to the contamination of the semiconductor packaging mold to be cleaned, including the moving speed of the telescopic cylinder 1277, the rotation speed of the face cutting knife disc, the pressure of the compressed air, etc., and the movement trajectory and movement speed of the cleaning robot 8 can also be controlled.

[0039] refer to Figure 2 , Figure 6 , the compressed air source inlet 26 is connected to the mixing bin 122 through the water filter device 16. Various pneumatic components are arranged in the second layer of the frame 1, and a compressed air source inlet 26 is arranged at the back of the equipment to provide driving airflow for various pneumatic components. The left side of the water filter 16 is an air inlet, which is first connected to the compressed air source inlet 26 to filter out oil, water and solid pollutants in the compressed gas of the main pipeline. The exhaust hole on the right side of the water filter 16 is provided with two branches, one of which is connected to the left side of the high platform threaded ball valve 20, and the other is connected to the left side of the gas treatment two-way connection 24. The upper side of the high platform threaded ball valve 20 is equipped with a coupling 21, which is used to connect with the reducer 22. The upper side of the reducer 22 is equipped with a second motor 23, which is used to drive the switch state of the high platform threaded ball valve 20 to control the circulation of the airflow. The right side of the high platform threaded ball valve 20 is connected to the electric control check valve 19, which is used to prevent the airflow from flowing back. The right side of the electric-controlled one-way valve 19 is connected to the compressed gas inlet 1223 of the mixing bin 122, so as to provide airflow to the mixing bin 122.

[0040] refer to Figure 7The cleaning robot 8 is arranged on the top of the frame 1 and fixed on the panel 9. The tool end of the cleaning robot 8 is equipped with a tool quick-change plate 81, which is convenient for fast clamping and replacing the nozzle bracket 82. The bottom of the nozzle bracket 82 is symmetrically equipped with a nozzle clamping plate 83 for clamping and fixing the cleaning nozzle 84. Figure 8 The nozzle outlets 842 of the cleaning nozzle 84 are symmetrically distributed, which is convenient for cleaning the upper mold and the lower mold of the semiconductor packaging mold at the same time. The air pipe is connected through the nozzle feed port 841, and the dry ice jet can reach a supersonic state after being accelerated inside the nozzle and is ejected from the nozzle outlet 842, which is easy to clean the stains that are difficult to handle on the mold surface.

[0041] During operation, the dry ice is stored in the dry ice storage chamber 126, and the push plate 1272, driven by the telescopic cylinder 1277, pushes the whole dry ice to one side of the surface cutting disc of the ice cutting device. After the first motor 121 is started, the first motor 121 drives the small sprocket 123, and the small sprocket 123 drives the large sprocket 125 via the chain, and the large sprocket 125 drives the surface cutting disc to cut the dry ice, thereby achieving the purpose of automatically cutting dry ice. The dry ice particles obtained after cutting fall into the mixing bin 122 under the action of gravity, and one side of the mixing bin 122 is a compressed gas inlet 1223. After being filtered, the compressed gas continuously provides airflow to the mixing tank 1222. After the airflow is mixed with the dry ice particles, it is blown out from the discharge port 1221. The discharge port 1221 is connected to the discharge connector 13. The other end of the discharge connector 13 is externally connected to the air pipe. After the other end of the air pipe is connected to the cleaning nozzle 84, a dry ice jet can be provided for the cleaning robot 8. After the cleaning robot 8 reaches the designated position according to the set planned route, it can clean the upper and lower molds of the semiconductor packaging mold. The operator only needs to control the cleaning robot 8, the dry ice crushing device 12 and other devices on the control panel 10. The setting of the cleaning robot 8 can effectively ensure the health and safety of the operator. In addition, the equipment is not only miniaturized but also equipped with casters, which is easy to move and can change the cleaning position at will according to the cleaning occasion. In addition, the entire cleaning process does not require the removal of the mold, and it can be cleaned with electricity. Since dry ice has a low temperature property, condensation may occur during operation. A large water receiving tank 14 and a large water receiving box 17 are installed in the device to handle condensed water caused by the condensation to a certain extent.

[0042] Through the scheme of this embodiment, the degree of automation is high, the work efficiency can be improved, and the condensed water is effectively treated to prevent the condensed water from damaging the equipment.
