Technical Field

[0001] This application relates to the technical field of capacitor production, and in particular to a liquid coating apparatus for capacitor surfaces. Background Technology

[0002] Capacitor coating technology is a crucial step in the manufacturing of electronic components, directly affecting the performance and reliability of capacitors. Currently, with the miniaturization and high performance of electronic devices, the requirements for capacitor coating processes are becoming increasingly stringent. Traditional coating methods mainly include dip coating, spray coating, and spin coating.

[0003] Currently, a capacitor surface liquid coating device includes a pool body containing a coating liquid; a support plate is fixedly connected to the pool body, and the capacitor leads are connected to the support plate so that the capacitor casing is placed in the pool body for coating treatment.

[0004] However, since the position of the support plate relative to the pool body is fixed, the position of the capacitor relative to the pool body is also fixed, which results in poor applicability. Utility Model Content

[0005] To improve applicability, this application provides a liquid coating apparatus for capacitor surfaces.

[0006] This application provides a liquid coating device for capacitor surfaces, which adopts the following technical solution: A capacitor surface liquid coating device includes a box, a pool, a hanging block, and a lifting mechanism. The pool is disposed on the box, and the hanging block is disposed on the box via the lifting mechanism, with the hanging block located above the pool.

[0007] By adopting the above technical solution, the coating liquid is placed in the pool, and the capacitor is hung on the hanging block; the lifting mechanism is activated, and the lifting mechanism drives the hanging block to rise and fall, which in turn drives the capacitor to rise and fall, thereby changing the position of the capacitor relative to the coating liquid in the pool; therefore, the capacitor surface liquid coating device provided in this application can improve applicability.

[0008] Optionally, the lifting mechanism includes a support block, an electric actuator, a lifting plate, a lifting rod, and a lifting block. The support block is disposed on the housing, the electric actuator is disposed on the support block, and the lifting plate is disposed on the piston rod of the electric actuator. The lifting rod is disposed on the lifting plate, the lifting block is disposed on the lifting rod, and the hanging block is disposed on the lifting block.

[0009] By adopting the above technical solution, the electric actuator is activated, which drives the lifting plate to move. The lifting rod on the lifting plate drives the lifting block to move, and the lifting block drives the hanging block to move, thereby changing the position of the hanging block.

[0010] Optionally, the lifting block is provided with a connecting assembly connected to the lifting rod. The connecting assembly includes a first connecting block, a second connecting block, a third connecting block, and a connecting bolt. The first connecting block is connected to the lifting block and has a receiving groove for placing the lifting rod. The third connecting block and the second connecting block are both disposed on the first connecting block, and a clamping groove communicating with the receiving groove is formed between the second connecting block and the third connecting block. The third connecting block has a first through hole, and the second connecting block has a first threaded hole. The connecting bolt passes through the first through hole and is threadedly connected to the first threaded hole.

[0011] By adopting the above technical solution, the end of the lifting rod away from the lifting plate is placed in the receiving groove of the first connecting block, and then the connecting bolt is threaded through the first through hole and threaded into the first threaded hole. The clamping groove will undergo a certain deformation, so the first connecting block will press against the lifting rod. The connecting component not only allows the lifting block to be detachably connected to the lifting rod, but also allows the position of the lifting block relative to the lifting rod to be adjusted as needed, thereby improving applicability.

[0012] Optionally, the lifting block includes a fourth connecting block, a fifth connecting block, and an adjusting component. The fourth connecting block is connected to the lifting rod, the fifth connecting block is mounted on the fourth connecting block via the adjusting component, and the hanging block is mounted on the fifth connecting block.

[0013] By adopting the above technical solution, the fifth adjusting block can be moved relative to the fourth adjusting block by adjusting the component as needed, so that the fifth adjusting block can move the hanging block, thereby changing the position of the hanging block and improving its applicability.

[0015] By adopting the above technical solution, rotating the screw cap causes the adjusting screw to rotate, which changes the length of the threaded connection between the adjusting screw and the second threaded hole, thereby causing the fifth connecting block to move relative to the fourth connecting block.

[0016] Optionally, the housing has a receiving cavity and a fourth through hole communicating with the receiving cavity, and the end of the lifting rod away from the lifting plate passes through the fourth through hole; the housing is provided with a guide assembly, the guide assembly includes a guide rod and a fixing plate, one end of the guide rod is connected to the housing and the other end is connected to the fixing plate, and the lifting plate has a fifth through hole for the guide rod to pass through.

[0017] By adopting the above technical solution, when the lifting plate moves, the fixing rod will slide in the fifth through hole of the lifting plate, thereby reducing the phenomenon of the lifting plate moving off course.

[0018] Optionally, the box body is provided with a covering mechanism, which includes a barrier block, a covering block and an adjustment component. The barrier block is disposed on the box body and has a receiving cavity. The pool body is located in the receiving cavity, and the covering block covers the receiving cavity through the adjustment component.

[0019] By adopting the above technical solution, when the capacitor is located in the coating liquid inside the pool, the adjustment component is activated. The adjustment component drives the cover block to move, so that the cover block covers the accommodating cavity, which can reduce the phenomenon of impurities entering the pool.

[0020] Optionally, the adjustment assembly includes an adjustment cylinder and an adjustment block, the cylinder body of the adjustment cylinder is hinged to the enclosure block, the adjustment block is disposed on the cover block, and the piston rod of the adjustment cylinder is hinged to the adjustment block.

[0021] By adopting the above technical solution, the adjusting cylinder is activated, and the piston rod of the adjusting cylinder will drive the adjusting block to move, which in turn drives the covering block to move.

[0022] Optionally, there are two lifting blocks, and the pool body is located between the two lifting blocks; each lifting block has a first placement slot, and a support mechanism is provided above the pool body. The support mechanism includes a support block and a sixth connecting block. There are two support blocks and two sixth connecting blocks. The two ends of the two sixth connecting blocks are respectively connected to the two support blocks. The two support blocks are respectively located in the first placement slots of the two lifting blocks, and each of the two support blocks has a second placement slot. The two ends of the hanging block are respectively located in the second placement slots of the two support blocks.

[0023] By adopting the above technical solution, when it is necessary to coat the capacitor, the capacitor is first hung on the hanging block, and then the two ends of the hanging block are respectively snapped into the second placement slots of the two support blocks; then the operator holds the two sixth connecting blocks to realize the transfer of the support blocks, and places the two support blocks into the first placement slots of the two lifting blocks respectively. In this way, when the lifting blocks move, the lifting blocks will drive the two support blocks to move, and the two support blocks will drive the position of the hanging block to change.

[0024] Optionally, the pool body is provided with two partition plates, which together form a coating area with the pool body. The remaining space in the pool body is located in the outflow area. The box body is provided with a circulation mechanism, which includes a circulation box, a connecting pipe, a power pump, an inlet pipe, and an outlet pipe.

One end of the outlet pipe is connected to the circulation box and the other end is connected to the pool body, and the outlet pipe communicates with the outflow area.

[0025] By adopting the above technical solution, the power pump is started, and the power pump brings the coating liquid in the circulation tank into the coating area through the connecting pipe and the inlet pipe.

A connecting bolt is provided on the third connecting block 253, and the first through hole and clamping groove on the third connecting block 253 at the end of the connecting bolt away from its own nut are threadedly connected to the first threaded hole on the second connecting block 252.

[0039] When the connecting bolt is threaded into the first threaded hole on the second connecting block 252 and the connecting bolt abuts against the third connecting block 253, the clamping groove will undergo a certain deformation, and the first connecting block 251 will abut against the lifting rod 24, thereby fixing the first connecting block 251 on the lifting rod 24.

[0040] refer to Figure 3 and Figure 4 The pool body 12 is located between four lifting rods 24, with two lifting rods 24 on one side of the pool body 12 and two more lifting rods 24 on the other side. A lifting block 3 is provided on both sides of the pool body 12, and the first connecting block 251 of the two lifting rods 24 located on the same side of the pool body 12 is connected to the lifting block 3.

Two adjusting screws 331 and two swivel caps 332 are provided on one fourth connecting block 31.

[0042] The operator's two hands simultaneously rotate the two caps 332, which drive the two adjusting screws 331 to rotate, causing the thread length of the two adjusting screws 331 and the second threaded hole on the fifth connecting block 32 to change. In this way, the fifth connecting block 32 will move relative to the fourth connecting block 31.

[0043] refer to Figure 3 and Figure 4 Each of the two fifth connecting blocks 32 has a first placement groove 321. A supporting mechanism 5 is provided between the two fourth connecting blocks 31. The supporting mechanism 5 includes two supporting blocks 51, which are respectively engaged with the first placement grooves 321 on the two fifth connecting blocks 32. Each of the two supporting blocks 51 has multiple second placement grooves 511 on the side of each other.

The two sixth connecting blocks 52 are located above the two supporting blocks 51.

[0044] The operator holds the two sixth connecting blocks 52 with both hands and moves the six connecting blocks 52. The two sixth connecting blocks 52 will drive the two supporting blocks 51 to move, so that the two supporting blocks 51 are respectively engaged in the two first placement slots 321 of the two fifth connecting blocks 32.

[0045] refer to Figure 1 and Figure 5 The covering mechanism 4 includes a containment block 41, which is fixedly connected to the upper end of the housing 11.

An adjustment block 432 is fixedly connected to the covering block 42, and the piston rod of the adjustment cylinder 431 is hinged to the adjustment block 432.

[0046] When the adjusting cylinder 431 is activated, the piston rod of the adjusting cylinder 431 will drive the adjusting block 432 to move, and the adjusting block 432 will drive the covering block 42 to move, so that the covering block 42 covers the receiving cavity 411.

[0047] In this embodiment, the coating liquid is an insulating liquid or a liquid adhesive.

[0048] The implementation principle of Embodiment 1 of this application is as follows: The operator first hangs the capacitor on the hanging block 13, and then the two ends of the hanging block 13 with the capacitor are respectively snapped into the second placement slots 511 of the two support blocks 51; then the operator holds the sixth connecting block 52 with both hands and moves the sixth connecting block 52, so that the two support blocks 51 are respectively snapped into the first placement slots 321 on the two fifth connecting blocks 32; so that the capacitor on the hanging block 13 is located in the coating area 121 of the pool body 12.

[0049] Start the electric actuator 22, causing the lifting rod 24 to move the first connecting block 251. The first connecting block 251 moves the fourth connecting block 31, and the fourth connecting block 31 moves the fifth connecting block 32. The two fifth connecting blocks 32 will then move the two supporting blocks 51, which in turn move the hanging block 13. The hanging block 13 will then move the capacitor. When fine-tuning is needed, the operator rotates the two caps 332 on the same fourth connecting block 31, causing the fifth connecting block 32 to move relative to the fourth connecting block 31.

[0050] Then, start the adjusting cylinder 431 to cover the receiving cavity 411 with the cover block 42. Finally, start the power pump 63 to allow the coating liquid in the circulation tank 61 to enter the coating area 121, and then flow back to the circulation tank 61 through the outflow area 122 and the liquid outlet pipe 65.

[0051] Example 2 refer to Figure 6 and Figure 7 The difference from Embodiment 1 is that a stabilizing component 7 is provided on the fifth connecting block 32.

An adjusting rack 72 is integrally provided on the stabilizing block 71. An adjusting shaft 73 is rotatably connected to the fifth connecting block 32, and an adjusting rack 72 that meshes with an adjusting gear 74 is keyed to the adjusting shaft 73.

[0052] Rotating the adjusting shaft 73 causes the adjusting gear 74 to rotate, which in turn causes the adjusting rack 72 to move. The adjusting rack 72 then causes the stabilizing block 71 to move, thus pressing the stabilizing block 71 against the support block 51 located in the first placement groove 321, thereby improving the stability of the support block 51 within the first placement groove 321.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
