Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component production, and particularly relates to an electrode wrapping and clamping mechanism capable of adapting to multi-size patch components. Background Art

[0002] To improve the surface insulation performance and protection of patch-type electronic component products, it is often necessary to apply a protective agent coating to the non-electrode area of the product. Especially for high-voltage patch products with kilovolts, it is necessary to insulate and protect the ceramic body part between the two electrodes to prevent surface arc ignition.

[0003] The current operation method uses a spraying operation technique. A fixed chuck corresponding to the product size is used to wrap and block the electrode area of the product, and an atomizing nozzle sprays the unblocked area in the middle of the product. Finally, the surface of the product is dried to cure the coating.

[0004] Disadvantages of the prior art:

[0005] 1. The chuck is a fixed part, and a plastic sleeve is used to wrap the two ends of the electrode to prevent the spraying liquid from being sprayed onto the electrode area of the product. Therefore, the chuck needs to have a high matching degree with the product size and there should be no excessive gap. Therefore, in order to adapt to various sizes of products, it is necessary to customize various types and models of chucks, which consumes costs and increases management difficulties;

[0006] 2. Due to the drying operation involved, the chuck may be deformed after aging, and there is a risk of electrode scraping during the process of the chuck moving towards the electrode. Summary of the Invention

[0007] The purpose of the utility model is to provide an electrode wrapping and clamping mechanism capable of adapting to multi-size patch components. According to different sizes of patch components, the forward pushing stroke of the semi-conical push head is determined, so that the rotating clamping arms fix the two electrode ends of the corresponding size of patch components, thereby adapting to multi-size patch component products and achieving the effect of saving tooling.

[0008] The technical solution of the utility model is: an electrode wrapping and clamping mechanism capable of adapting to multi-size patch components, including two chuck assemblies symmetrically arranged on the two electrode ends of the patch component on the left and right respectively. The chuck assembly includes a movable base with a circular perforation in the center position, a cylindrical push rod fixedly connected to the output end of a micro motor and capable of making a reciprocating motion back and forth along the circular perforation, a semi-conical push head arranged at the front end of the cylindrical push rod, and four groups of rotating clamping arms arranged on the movable base and evenly distributed around the semi-conical push head; at the same time, a heat-resistant silicone film for wrapping the two electrode ends of the patch component is covered on the top of the rotating clamping arm.

[0009] As a preferred technical solution, the rotating clamping arm includes a support rod vertically arranged on the movable base, an L-shaped rotating arm rotatably connected to the top of the support rod, a clamping jaw arranged at the top end of the L-shaped rotating arm and bent inward, and a rotating wheel arranged at the bottom end of the L-shaped rotating arm and capable of rolling along the surface of the semi-conical push head.

[0010] As a preferred technical solution, a cylindrical guide tube for the front and back reciprocating movement of the cylindrical push rod is arranged on the lower surface of the movable base, and the inner diameter of the cylindrical guide tube matches the diameter of the cylindrical push rod.

[0011] As a preferred technical solution, the middle part of the upper section of the L-shaped rotating arm is connected to the top of the support rod through a rotating shaft.

[0012] As a preferred technical solution, the heat-resistant silica gel film is fixed to the outer side wall of each clamping jaw through fastening screws.

[0013] As a preferred technical solution, the rotating wheel is a rubber roller.

[0014] As a preferred technical solution, the L-shaped rotating arm and the clamping jaw are integrally formed.

[0015] The advantages of the present utility model are as follows:

[0016] 1. The present utility model can be adapted to the electrode wrapping and clamping mechanisms of multi-size patch components. According to different sizes of patch components, the forward pushing stroke of the semi-conical push head is determined, so that the rotating clamping arm fixes the two electrode ends of the corresponding size of patch components, thereby adapting to multi-size patch component products, achieving the effect of saving tooling.

[0017] 2. The present utility model uses a heat-resistant silica gel film to wrap the two electrode ends of the patch component. The heat-resistant silica gel film is not only heat-resistant but also elastic, which can effectively reduce the risk of electrode end abrasion and improve the overall service life at the same time.
