[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example

[0038] The present invention provides a three-gun vacuum epoxy resin glue filling device for capacitors, such as Figure 1-Figure 11 As shown, it includes an operating platform 1, which is a rectangular box structure, which is spliced ​​by prefabricated steel profiles and plates. Several pulleys are installed at the bottom of the operating platform 1. The number of pulleys is 4, all of which are fixed to the bottom of the operating platform 1 by bolts, and the pulley structure has a self-locking function. An operating box 2 is installed on the top of the operating platform 1. The operating box 2 is a rectangular structure with a hollow interior. It is welded by a whole piece of steel plate, so that it has good sealing performance. A partition 203 is installed in the operating box 2. The partition 203 is welded to the inner wall of the operating box 2. The partition 203 divides the operating box 2 into two operating spaces, which are a first chamber 210 and a second chamber 209. A first inlet and outlet 201 is opened on the partition 203, and the first inlet and outlet 201 is rectangular. Both sides of the first inlet and outlet 201 are provided with a groove structure. A second inlet and outlet 202 is provided on the side wall of the operation box 2, and the second inlet and outlet 202 is communicated with the second chamber 209, and the first inlet and outlet 201 is directly opposite to the second inlet and outlet 202. The second inlet and outlet 202 is also rectangular.

[0039] First sealing plates 204 are installed on both sides of the first inlet and outlet 201. The first sealing plates 204 are in the shape of plates. A driving mechanism is installed in the partition 203. When the driving mechanism drives one of the first sealing plates 204 to move, the other sealing plate is relatively stationary. Fixing mechanisms for fixing the material tray 12 are installed on the opposite side walls of the two first sealing plates 204.

[0040] A second sealing plate 501 is installed in the second inlet and outlet 202, and a positioning mechanism for driving the second sealing plate 501 to rotate is installed on the side wall of the operation box 2. A material conveying mechanism is arranged on the outer side wall of the operation box 2.

[0041] Two sets of vacuum pumping equipment are installed in the operating platform 1, which are connected to the first chamber 210 and the second chamber 209 respectively. The vacuum pumping equipment is conventional technology. A glue coating mechanism for coating glue is installed in the first chamber 210.

[0042] In actual use, the first chamber 210 and the second chamber 209 need to be evacuated separately by using vacuum equipment.

[0043] The operation steps are as follows: the two first sealing plates 204 are respectively located on both sides of the first inlet and outlet 201 under the drive of the driving mechanism, and the first inlet and outlet 201 is closed, so that the first chamber 210 and the second chamber 209 are separated and not connected to each other. Then the first chamber 210 is exhausted by the vacuum device to keep it in a vacuum state. The driving mechanism drives the first sealing plate 204 seat close to the second chamber 209 to move clockwise, so that the first sealing plate 204 remains horizontal in the second chamber 209, and then the second sealing plate 501 is driven by the regulating machine to remove the shielding of the second inlet and outlet 202. At this time, the material tray 12 is transported from the second inlet and outlet 202 to the second chamber 209 by the material conveying mechanism, and the material tray 12 is seated on the first sealing plate 204 located in the second chamber 209. The fixing mechanism located on the first sealing plate 204 fixes the material tray 12. Then the second sealing plate 501 is driven by the regulating machine to shield the second inlet and outlet 202 again, isolating it from the atmospheric environment. The second chamber 209 is vented by a vacuum device to maintain a relative vacuum state. Then, the first sealing plate 204 near the second chamber 209 is driven by a driving mechanism to move counterclockwise, and the tray 12 enters the first inlet and outlet 201 driven by the first sealing plate 204. Until it contacts the first sealing plate 204 placed in the first chamber 210 and is fixed by a fixing mechanism arranged on the first sealing plate 204. The first sealing plate 204 near the first chamber 210 is driven by a driving mechanism to move counterclockwise again, so that the first sealing plate 204 moves to the first chamber and maintains a horizontal state. Another first sealing plate 204 serves to isolate the first chamber 210 from the second chamber 209. The gluing mechanism located in the first chamber 210 performs a gluing operation on the sensor to be processed. The above structure effectively blocks the air from entering the first chamber 210, causing air to exist inside the colloid applied to the sensor, making it easy for bubbles to form on the glue surface, and there is a risk of unstable product appearance quality and quality defects in the packaging effect of the product.

[0044] In some technical solutions of the present invention, the material transmission mechanism includes a mounting frame 6 mounted on the outer wall of the operating box 2, and the mounting frame 6 is L-shaped and made of prefabricated steel. A conveyor belt 602 connected end to end is rotatably provided on the mounting frame 6, and two transmission shafts 601 connected to the conveyor belt 602 are rotatably provided on the mounting frame 6. The two ends of the conveyor belt 602 are in a straight state under the action of two transmission rollers. The material of the conveyor belt 602 is rubber material, which has outstanding wear resistance. Under the joint drive of the conveyor belt 602 and the transmission shaft 601, the material tray 12 can be smoothly fed into the first inlet and outlet 201 and placed on the first sealing plate 204 in the second chamber 209, so as to speed up the feeding efficiency of the above structure for the sensor glue coating. A first drive motor 208 connected to one of the transmission shafts 601 is installed on the mounting frame 6. The first drive motor 208 is a servo motor, which makes it easy for the operator to accurately transport the corresponding material tray 12 to the specified position. The complete material tray 12 is relative to the input and output in the operation box 2, which improves the convenience of the operator operating the above structure to perform gluing operations.

Through the above structure, the second chamber 209 can also maintain the same vacuum environment as the first chamber 210, avoiding air from mixing into the first chamber 210 from the second chamber 209. Ensure that the above structure completes the gluing operation of the sensor with quality and quantity. The fifth drive motor 5 connected to the positioning shaft 502 is installed on the positioning frame 503.

A first sealing groove adapted to the first sealing ring 211 is provided on the side wall of the partition 203. In this way, when the first sealing plate 204 is attached to the partition 203 under the drive of the driving mechanism, a part of the first sealing ring 211 located on the first sealing plate 204 will be embedded in the first sealing groove, and under the action of the inflation of the inflation device, the first sealing ring 211 expands in the first sealing groove to fill the gap between the two, so as to avoid the problem of the first chamber 210 being not tightly sealed. It is prevented that after the air and other substances enter the first chamber 210, air appears on the glue-coated surface of the colloid and the sensor, and bubbles are generated.
