Description

Technical Field

[0001] This utility model belongs to the field of thermal grease coating technology, and in particular relates to a rapid positioning thermal grease coating device. Background Technology

[0002] Thermal grease, commonly known as heat dissipation paste, is applied to electronic components for heat conduction and dissipation, thereby ensuring the stable electrical performance of electronic instruments and meters. Currently, when manually applying thermal grease to inverters during assembly, operators first use a roller brush to fully coat the inverter's heat dissipation surface before screwing it onto the plastic casing. While this brushing method is efficient, it can cause thermal grease to get into the threaded holes of the inverter's heat dissipation surface, making subsequent screw removal difficult. This method of applying thermal grease all over the surface also results in material waste and increased production costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to improve the thermal grease coating device for quickly locating specific heat dissipation areas on the heat dissipation surface of a frequency converter.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a rapid positioning thermal grease coating device, comprising a tooling table, a base plate, a telescopic cylinder, columns, a support, a clamping block, a guide rod, a spring, a guide sleeve, a brush plate seat, and a coating brush. The base plate is fixedly installed at the bottom of the tooling table, the cylinder body of the telescopic cylinder is fixedly installed on the base plate, the piston rod of the telescopic cylinder slides through the top surface of the tooling table, four columns are rectangularly distributed and fixedly installed on the top surface of the tooling table, the guide sleeve and the brush plate seat are both fixedly sleeved on the top of the four columns, the guide sleeve has a guide hole inside, and the front side of the guide sleeve has a feeding opening. The support is fixedly installed on the top of the telescopic cylinder. Four guide rods are distributed in pairs, symmetrically distributed at their inner ends and fixedly installed on the support. The clamping block is slidably sleeved on the outer end of the guide rod. The outer end of the guide rod is screwed with an anti-disengagement stop ring acting on the outer end face of the clamping block. The spring is sleeved on the guide rod. The two ends of the spring act on the support and the clamping block respectively. The clamping block is slidably installed in the guide sleeve. Under the action of the spring force, the clamping block is always pressed against the inner wall of the guide sleeve. The contact surface between the clamping block and the guide sleeve is set as an inclined structure. The coating brush is fixedly installed on the brush plate seat. The brush plate seat is provided with a coating through hole for the frequency converter to pass through.

[0005] Preferably, the guide hole is configured as a square hole structure.

[0006] Preferably, an elastic rubber pad is fixedly provided on the clamping surface of the clamping block.

[0007] Preferably, an anti-slip rubber pad is fixedly attached to the bottom surface of the base plate.

[0008] Compared with the prior art, the advantages of this utility model are: this device places the frequency converter on the support, and the piston rod of the telescopic cylinder extends, which can realize the clamping and positioning of the frequency converter by the clamping block. It has the advantage of fast positioning speed. At the same time, it can also push the frequency converter upward to contact the coating brush plate. The first through hole corresponding to the coating brush plate can apply thermal grease to specific positions on the heat dissipation surface of the frequency converter, which can avoid the waste of thermal grease material and the problem of brushing thermal grease into the threaded hole.

[0013] The present invention will now be described in detail with reference to specific embodiments:

[0014] like Figures 1 to 3The illustrated rapid positioning thermal grease coating device includes a fixture 1, a base plate 11, a telescopic cylinder 2, columns 3, a support 4, a clamping block 41, a guide rod 42, a spring 43, a guide sleeve 5, a brush plate seat 6, and a coating brush 7. The base plate 11 is fixedly installed at the bottom of the fixture 1. The cylinder body of the telescopic cylinder 2 is fixedly installed on the base plate 11, and the piston rod of the telescopic cylinder 2 slides through the top surface of the fixture 1. Four columns 3 are rectangularly distributed and fixedly installed on the top surface of the fixture 1. The guide sleeve 5 and the brush plate seat 6 are both fixedly sleeved on the top of the four columns 3. The guide sleeve 5 has a guide hole 51 inside and a feeding opening on the front side. The support 4 is fixedly installed on the top of the telescopic cylinder 2. The unit has four guide rods 42 distributed symmetrically in pairs on their inner ends and fixedly installed on the support 4. The clamping block 41 is slidably sleeved on the outer end of the guide rod 42. The outer end of the guide rod 42 is screwed with an anti-disengagement stop ring acting on the outer end face of the clamping block 41. The spring 43 is sleeved on the guide rod 42. The two ends of the spring 43 act on the support 4 and the clamping block 41 respectively. The clamping block 41 is slidably installed in the guide sleeve 5. Under the action of the spring force of the spring 43, the clamping block 41 is always pressed against the inner wall of the guide sleeve 5. The contact surface between the clamping block 41 and the guide sleeve 5 is set as an inclined structure. The coating brush 7 is fixedly installed on the brush plate seat 6. The brush plate seat 6 is provided with a coating through hole for the frequency converter 10 to pass through.

[0015] The guide hole 51 is configured as a square hole structure, which can restrict the degree of freedom of the clamping block 41 in the front and back directions, and prevent the combination of clamping block 41, support 4 and piston rod of telescopic cylinder 2 from rotating.

[0016] An elastic rubber pad 44 is fixedly provided on the clamping surface of the clamping block 41. The elastic rubber pad 44 has the characteristic of being compressible, which can prevent the clamping block 41 from having excessive stroke close to the inverter 10, which would cause the inverter 10 housing to be squeezed and damaged.

[0017] An anti-slip rubber pad is fixedly attached to the bottom surface of the base plate 11. The anti-slip rubber pad can improve the stability of the device when placed on the operating table and play an anti-slip role.

[0018] The inverter 10 is placed on the support 4 through the loading opening. The piston rod of the telescopic cylinder 2 is extended outward, pushing the support 4 and the clamping block 41 upward. Under the guiding action of the inclined structure, the clamping block 41 overcomes the elastic force of the spring 43 and moves closer to the inverter 10 to clamp and fix it. At this time, the heat dissipation surface of the top of the inverter 10 is located in the coating through hole. The operator uses the coating brush 7 with the corresponding position of the first through hole to apply thermal conductive silicone grease to the specific heat dissipation area on the top surface of the inverter 10. After the operation is completed, the piston rod of the telescopic cylinder 2 retracts, driving the support 4 and the clamping block 41 downward. Under the action of the elastic force of the spring 43, the clamping block 41 moves outward, releasing the action on the inverter 10, and the inverter 10 can be removed.
