Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] This embodiment provides a multi-glue mixing and potting system, which aims to increase the number of glue tanks, enable them to be automatically switched in the potting equipment, and add the function of automatically cleaning the pipelines of the filling mechanism, so as to achieve the purpose of quickly replacing different glues.

[0033] Reference Figure 1 、 Figure 2 The multi-glue mixing and potting system shown in the figure includes: a plurality of AB glue generating devices 1, two glue mixing devices 2, one cleaning liquid generating device 3, one compressed air generating device 4, one first transposition module 5 and one second transposition module 6.

[0034] A plurality of AB glue generating devices 1 are connected to the first transposition module 5, and the first transposition module 5 is used to drive the plurality of AB glue generating devices 1 to move synchronously, so that one of the AB glue generating devices 1 moves to the potting station.

[0035] The cleaning liquid generating device 3 and the compressed air generating device 4 are arranged at the cleaning station.

[0036] The two glue mixing devices 2 are connected to the second transposition module 6, and the second transposition module 6 is used to drive the two glue mixing devices 2 to move synchronously, so that one of the glue mixing devices 2 moves to the potting station and is connected to the AB glue generating device 1 also located at the potting station, and the other glue mixing device 2 moves to the cleaning station and is connected to the cleaning liquid generating device 3 and the compressed air generating device 4 also located at the cleaning station.

[0037] The working principle of the multi - glue mixing and potting system includes:

[0038] Step 1, potting AB glue: An AB glue generating device 1 is connected to a glue mixing device 2 at the potting station, and the mixed AB glue is filled onto the surface of the circuit board.

[0039] Step 2, replacing AB glue: The first transposition module 5 and the second transposition module 6 drive another AB glue generating device 1 to be connected to another glue mixing device 2 at the potting station. At this time, the used glue mixing device 2 is connected to a cleaning liquid generating device 3 and a compressed air generating device 4 at the cleaning station. The cleaning liquid generating device 3 outputs cleaning liquid to the glue mixing device 2 to clean it, and then the compressed air generating device 4 outputs dry air to the glue mixing device 2 to dry it.

[0040] A waste liquid bucket is provided at the cleaning station, and the mixed liquid of the residual AB glue and the cleaning liquid inside the glue mixing device 2 flows into the waste liquid bucket.

[0041] Reference Figure 5 , the AB glue generating device 1 includes: two glue cartridges 11, two first liquid pumps 12 and two first stop valves 13. Each glue cartridge 11 is sequentially connected to a first liquid pump 12 and a first stop valve 13, and is fixedly connected to the actuator of the first transposition module 5.

[0042] The first liquid pump 12 is preferably a screw pump. The first liquid pump 12 is used to transport the glue from the glue cartridge 11 to the glue mixing device 2, and the first stop valve 13 is used to close the output end of the AB glue generating device 1 to prevent glue leakage when the AB glue generating device 1 is separated from the glue mixing device 2.

[0043] Reference Figure 1 , Figure 2 , Figure 3 , the first transposition module 5 adopts a servo screw slide 63. A double - layer bracket 65 is provided on the slider of the servo screw slide 63. Two glue cartridges 11 are installed on the upper layer of the double - layer bracket 65, two first liquid pumps 12 are installed on the lower layer of the double - layer bracket 65, and the first stop valves 13 are installed on the suspension connected to one side of the double - layer bracket 65.

[0044] Reference Figure 3 , Figure 4 , the glue mixing device 2 includes: a mixing tube 21 and a pushing cylinder 22.

[0045] The mixing tube 21 has two pressurizing chambers 211, one mixing chamber 212, two input ends and one output end. Each input end of the mixing tube 21 is connected to a pressurizing chamber 211 and the output end of a first stop valve 13, and the output end of the mixing tube 21 is connected to the mixing chamber 212.

[0046] The two pressurizing chambers 211 are not connected to each other. Both of the two pressurizing chambers 211 are connected to the mixing chamber 212. The pressurizing chamber 211 is cylindrical in shape. A pressurizing piston 213 is arranged inside the pressurizing chamber 211. The actuating part of the pushing cylinder 22 passes through the mixing pipe 21 to connect to the pressurizing piston 213, so as to drive the pressurizing piston 213 to move along the axis of the pressurizing chamber 211.

[0047] The working principle of the glue mixing device 2 is as follows: The two glue cartridges 11 respectively deliver glue to the two pressurizing chambers 211 through their respective first liquid pumps 12 and first stop valves 13. During the potting operation, the pushing cylinder 22 drives the two pressurizing pistons 213 to move inside the pressurizing chambers 211, so that the glue is squeezed into the mixing chamber 212. The fully mixed glue flows out through the output end of the mixing pipe 21. The pushing cylinder 22 and the pressurizing piston 213 perform a reset action between two potting operations.

[0048] Further, referring to Figure 4 , each of the two pressurizing pistons 213 is connected with a piston rod 214. The two piston rods 214 are connected to the actuating part of the pushing cylinder 22 through a connecting rod 221. The pushing cylinder 22 drives the two pressurizing pistons 213 to move synchronously at the same time.

[0049] Referring to Figure 6 , the cleaning liquid generating device 3 includes a cleaning liquid cartridge 31, a second liquid pump 32, a second stop valve 33 and a four-way joint 34. The cleaning liquid cartridge 31, the second liquid pump 32, the second stop valve 33 and one port of the four-way joint 34 are sequentially connected and are all fixedly connected to the frame. The other two ports of the four-way joint 34 are respectively used to connect the two input ends of the glue mixing device 2, and the remaining one port of the four-way joint 34 is used to connect the output end of the compressed air generating device 4.

[0050] Referring to Figure 6 , the compressed air generating device 4 includes an air compressor 41, a compressed air storage cylinder 42 and a third stop valve 43. The air compressor 41, the compressed air storage cylinder 42 and the third stop valve 43 are sequentially connected and are all fixedly connected to the frame.

[0051] Among them, the third stop valve 43 serves as the output end of the compressed air generating device 4 and is connected to the remaining one port of the four-way joint 34.

[0052] It should be noted that Figure 6 the four-way joint 34 shown in

[0053] substantially has five ports. Among them, two ports have the same function and are both connected to the output end of the second liquid pump 32.

[0054] The cleaning liquid cartridge 31 is used to store the cleaning liquid. When the second shut-off valve 33 is opened and the third shut-off valve 43 is closed, the second liquid pump 32 is used to transport the cleaning liquid from the cleaning liquid cartridge 31 to the two pressurizing chambers 211 of the mixing tube 21. The cleaning liquid flows along the sequence of the pressurizing chamber 211, the mixing chamber 212, and the waste liquid bucket, so as to clean the glue remaining inside the mixing tube 21.

[0055] The air compressor 41 is used to generate compressed air and transport the compressed air to be stored inside the compressed air storage cylinder 42. When the second shut-off valve 33 is closed and the third shut-off valve 43 is opened, the compressed air is transported to the two pressurizing chambers 211 of the mixing tube 21 after passing through the pressure reducing valve, the third shut-off valve 43, and the four-way joint 34. The dry air flows along the sequence of the pressurizing chamber 211, the mixing chamber 212, and the waste liquid bucket, so as to blow out the mixed liquid of the cleaning liquid and the glue remaining inside the mixing tube 21.

[0056] Reference Figure 3 、 Figure 4 The second transposition module 6 includes a turntable 61 and a sliding table 63. The axis of the turntable 61 is arranged in the vertical direction. Two sliders capable of moving in the horizontal direction are arranged on the sliding table 63. Each slider is respectively connected to a bracket 65. The mixing tube 21 and the pushing cylinder 22 are both fixedly connected to the bracket 65.

[0057] The turntable 61 includes a motor 62. The turntable 61 is driven by the motor 62, so as to realize the automatic rotation of the sliding table 63. The two glue mixing devices 2 perform circular motion through the turntable 61 to exchange positions, so as to change the working positions of each glue mixing device 2.

[0058] The sliding table 63 includes a wide finger cylinder 64. The two sliders are driven by the wide finger cylinder 64, so as to realize the automatic translation of the glue mixing device 2.

[0059] Furthermore, quick-connect female connectors are provided at the output ends of the first shut-off valves 13. Quick-connect female connectors are also provided at the two output ports of the four-way joint 34. Quick-connect male connectors are installed at the two input ends of the mixing tube 21. The moving direction of the slider is parallel to the plugging direction of the quick-connect male connector. The quick-connect female connector is used to quickly plug in or disconnect from the quick-connect male connector, so that the input end of the glue mixing device 2 can be connected to both ends of the two first shut-off valves 13 or the four-way joint 34 through the horizontal movement of the sliding table 63.
