Description

Technical Field

[0001] This utility model relates to the field of inverter manufacturing technology, specifically to a ceramic plate arrangement mechanism. Background Technology

[0002] Inverters typically contain multiple power components, which generate significant heat and require heat sinks to dissipate it effectively. Ceramic plates serve as the heat transfer intermediaries connecting the power components and the heat sinks. To improve the contact and adhesion between the ceramic plate surface and both the power components and the heat sink, thermal grease is applied to both surfaces of the ceramic plate.

[0003] The existing method of applying thermal grease to ceramic heat sinks is inefficient and has significant limitations. Currently, the ceramic heat sinks are manually placed on a fixture, grease is applied to one side of the heat sink, the heat sink is placed on the fixture, and then the fixture and heat sink are rotated 180 degrees to transfer the ceramic heat sink onto the heat sink. After removing the fixture, grease is applied to the other side of the ceramic heat sink on the heat sink. Because this requires multiple handling and rotations, and especially when the heat sink is large and heavy, the entire process is time-consuming, labor-intensive, and has high labor costs and intensity.

[0004] In order to improve the efficiency of ceramic sheet adhesive application, the applicant intends to propose a suction cup device to assist in the adhesive application and installation of ceramic sheets, and at the same time, needs to propose a ceramic sheet arrangement mechanism that can improve the efficiency of placing ceramic sheets onto the suction cup device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a ceramic sheet stacking mechanism.

[0006] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a ceramic sheet arranging mechanism, used to automatically arrange ceramic sheets on a suction cup device, the suction cup device including a ceramic sheet placement seat, the bottom surface of which is provided with multiple ceramic sheet positioning grooves for placing ceramic sheets;

[0007] The ceramic tile arranging mechanism includes a linear shifting mechanism and a ceramic tile arranging box. The linear shifting mechanism is mounted on the ceramic tile placement seat of the suction cup device. A quick positioning structure is provided between the ceramic tile arranging box and the slider of the linear shifting mechanism. The ceramic tile arranging box has a stacking cavity for stacking ceramic tiles. The bottom of the stacking cavity has a lower opening for the ceramic tiles to fall. Under the drive of the linear shifting mechanism, the lower opening of the stacking cavity of the ceramic tile arranging box is sequentially matched with each ceramic tile positioning slot arranged in a row on the ceramic tile placement seat.

[0008] This invention only requires pre-positioning multiple ceramic sheets in the ceramic sheet arrangement box. As the linear displacement mechanism drives the ceramic sheet arrangement box to move, the ceramic sheets are then placed into the ceramic sheet positioning slots on the suction cup device. This increases the arrangement speed of ceramic sheets on the suction cup device and improves work efficiency.

[0009] Furthermore, the linear shifting mechanism includes a rodless cylinder, a slice switch, and a slice reversing valve. The air inlet of the slice switch is connected to the air outlet of the air pump via a pipeline, and the air outlet of the slice switch is connected to the air inlet of the slice reversing valve via a pipeline. The first air outlet of the slice reversing valve is connected to one air port of the rodless cylinder, and the second air outlet of the slice reversing valve is connected to the other air port of the rodless cylinder.

[0010] Furthermore, a speed control valve is installed at both ports of the rodless cylinder.

[0011] By adopting the above-mentioned preferred solution, the pneumatic linear displacement mechanism of the rodless cylinder helps to make the suction cup device lighter.

[0012] Furthermore, the rapid positioning structure includes a positioning iron plate fixedly installed on the slider of the linear displacement mechanism, and a magnet and a positioning pin fixedly installed on the lower surface of the ceramic sheet stacking box. The positioning iron plate is provided with a positioning hole that matches the positioning pin.

[0013] The above-mentioned preferred solution facilitates quick docking between the ceramic sheet stacking box and the suction cup device, thereby improving work efficiency.

[0014] Furthermore, with the thickness of the ceramic sheet as d, the groove depth of the ceramic sheet positioning groove of the ceramic sheet placement seat as a, and the distance between the bottom surface of the stacking cavity of the ceramic sheet stacking box and the upper surface of the ceramic sheet placement seat as b, then, 0 <a<d,d-a<b<2d-a。

[0015] Furthermore, the lower opening of the stacking cavity is provided with outwardly flared chamfered surfaces on both sides perpendicular to the moving direction of the ceramic sheet stacking box. The angle between the chamfered surfaces and the horizontal plane is 40-60°, and the distance of the chamfered surfaces in the height direction is c, then c = 2d - a - b + 0.2 mm.

[0016] By adopting the above-mentioned preferred scheme, the bottom ceramic sheet can enter the ceramic sheet positioning groove at an angle at the front end in the forward direction, thereby improving the smoothness and reliability of ceramic sheet placement. Attached Figure Description

Chamfered surfaces 424 that expand outward are provided on both sides perpendicular to the moving direction of the ceramic chip arranging box at the lower opening of the stacking cavity 421. The included angle between the chamfered surface 424 and the horizontal plane is 40 - 60°, and the distance of the chamfered surface 424 in the height direction is c, then c = 2d - a - b + 0.2 mm.

[0051] The method for applying thermal grease to ceramic heat sinks includes the following steps:

[0052] Step 1: Divide the first ceramic plate positioning groove of the heat sink into multiple areas, make a relay positioning frame, design through positioning ports on the relay positioning frame to match the multiple areas, make a suction cup device to match the through positioning ports, and make the position of the second ceramic plate positioning groove on the suction cup device to match the first ceramic plate positioning groove in the through positioning port.

Apply thermal conductive silicone grease to the first exposed surface of the ceramic sheet.

[0055] Step 4: Flip the suction cup device 180 degrees and place it inside the through positioning hole of the relay positioning frame;

[0056] Step 5: Blow air into the main gas channel through the gas control mechanism. The airflow in the vacuum suction cup blows the ceramic sheet into the first ceramic sheet positioning groove on the radiator, and then removes the suction cup device.

[0057] Step 6: Apply thermal grease to the exposed second surface of the ceramic plate on the heat sink.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model.
