[0002] As a widely used electronic component in electronic devices, capacitors have strict requirements for their performance and reliability. High-performance polyurethane potting compound has high elasticity and flexibility, which can adapt to the size changes of capacitors in different environments, buffer external impacts, and protect internal components.

[0003] Current high-performance polyurethane potting compound filling devices for capacitors often experience air leakage and empty suction during material intake, leading to insufficient filling volume. Additionally, capacitor potting compound dries easily and must be properly stored before filling to prevent excessive exposure to air, which could cause blockage of the filling device.

[0004] To address the aforementioned issues, a high-performance polyurethane potting compound filling device for capacitors is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a high-performance polyurethane potting compound filling device for capacitors, which solves the problem in the background art that the filling head of the current high-performance polyurethane potting compound filling device for capacitors has air leakage and empty suction when sucking material, resulting in insufficient filling volume. At the same time, the potting compound for capacitors is easy to dry and must be properly stored before filling to prevent the raw material from being excessively exposed to the air, which would cause the filling device to be blocked.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-performance polyurethane potting compound filling device for capacitors, comprising a fixing mechanism, a filling conveying mechanism fixedly disposed at the upper end of the fixing mechanism, a filling adjustment mechanism disposed at the output end of the filling conveying mechanism, the fixing mechanism comprising a housing, a conveying assembly for conveying filling bottles fixedly disposed on the housing, the filling conveying mechanism comprising a negative pressure pump box fixedly disposed at the upper end of the fixing mechanism, a filling adjustment mechanism connected to one end of the negative pressure pump box, a filling tube for conveying potting compound fixedly disposed on one side of the fixing mechanism, the filling adjustment mechanism comprising a negative pressure tube connected to the negative pressure suction end of the negative pressure pump box, a filling outer frame connected to the output end of the filling tube, the filling outer frame being fixedly disposed, a suction assembly being vertically disposed between the filling outer frame and the negative pressure tube, a sealing element being sealed at the lower end of the filling outer frame, and a negative pressure plug being movably engaged inside the sealing element.

[0007] Preferably, the fixing mechanism further includes a support frame fixedly installed on the upper end of the chassis, a vertical plate connected to one side of the conveying component, a drive motor installed on one side of the conveying component, and an L-shaped frame screwed to the upper end of the vertical plate.

[0008] Preferably, a filter tube is connected to one side of the negative pressure pump box, a fixing member is fixedly installed on one side of the negative pressure pump box, and a lifting component is fixedly installed at the upper center of the fixing member.

[0009] Preferably, the lifting assembly includes a telescopic rod fixedly disposed at the upper center of the fixing member, and a lifting frame is provided at the output end of the telescopic rod, the lifting frame being interlocked with the suction assembly.

[0010] Preferably, the output end of the dispensing tube is connected to a dispensing tube, and the dispensing tube is in communication with the filling frame.

[0011] Preferably, the suction assembly includes a lifting block that engages with the lifting frame and a piston connected to the lower end of the suction assembly.

[0013] Preferably, the negative pressure plug has a transverse groove and an oblique opening at its lower end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides a high-performance polyurethane potting compound filling device for capacitors. By setting a sealing line for the potting compound through the filling tube, the sealing line is raised to prevent drying and reduce the amount of material left after filling. This solves the problem that the current high-performance polyurethane potting compound for capacitors is prone to drying and must be properly stored before filling to prevent the raw material from being excessively exposed to the air, which can lead to blockage of the filling device.

[0016] 2. This utility model provides a high-performance polyurethane potting compound filling device for capacitors. Through the combination of a filling adjustment mechanism and a filling conveying mechanism, a negative pressure pump box achieves negative pressure drive. Before filling, the negative pressure pump box needs to be started to expel the air in the negative pressure pipe, so that the negative pressure plug, which is movable at the lower end of the negative pressure pipe, moves up to block the negative pressure pipe. Then, the suction component is driven to rise, sucking the potting compound from the filling pipe into the cavity between the suction component and the filling frame. After that, the negative pressure pump box is closed, and the suction component is driven to press down, so that the negative pressure plug moves down. The potting compound can be squeezed downward through the negative pressure plug and the sealing element to complete the filling. The filling quantity can be achieved by controlling the lifting distance of the suction component. The negative pressure blocking setting of the negative pressure plug effectively prevents empty suction, solving the problem that the filling head of the current high-performance polyurethane potting compound filling device for capacitors has air leakage and empty suction when sucking material, resulting in insufficient filling volume.

[0028] Specifically, the housing 11 serves a fixing function, the support frame 12 drives the filling bottle to move and align with the filling adjustment mechanism 3 to complete the filling.

A lifting component 23 is fixedly installed at the upper center of the fixing component 22. The filter tube 211 and the negative pressure tube 33 are connected to the two ends of the negative pressure pump. The fixing component 22 supports the lifting component 23. The lifting component 23 realizes filling control.

[0033] The lifting assembly 23 includes a telescopic rod 231 fixedly installed at the upper center of the fixing member 22. The output end of the telescopic rod 231 is provided with a lifting frame 232. The lifting frame 232 is engaged with the suction assembly 32. The telescopic rod 231 drives the lifting frame 232 to lift the suction assembly 32.

The dispensing tube 241 is connected to the side end of the suction assembly 32 at the lowest pressing position, so that the suction assembly 32 can pick up the potting glue when it moves upward.

[0035] Example 2:

[0036] Combination Figure 6 and Figure 7 The suction component 32 includes a lifting block 321 that is engaged with the lifting frame 232, and a piston 322 connected to the lower end of the suction component 32.
