[0048] In addition, the applicant improved the sealing welding process of the power component filling tube by setting a sealing edge at the sealing end 103 to replace the manual operation of adding welding wire to the temperature sensing tube 100, thereby reducing the production steps of the welding process, reducing the production difficulty, and improving the production quality.

[0049] In one embodiment, the material positioning component 3 includes a first positioning bracket 31 arranged on the fixed base 11, a first positioning cylinder 32 arranged on the first positioning bracket 31, and a first positioning block 33 arranged at the output end of the first positioning cylinder 32; the welding rod positioning component 5 includes a second positioning bracket 51 arranged on the fixed base 11, a second positioning cylinder 52 arranged on the second positioning bracket 51, and a second positioning block 53 arranged at the output end of the second positioning cylinder 52.

In this way, the depth of the welding rod inserted into the sealing edge is limited to ensure that after the welding coil 601 melts the sealing edge, the molten material formed by the sealing edge can fully seal the gap between the welding rod and the sealing end 103.

[0050] In one embodiment, the welding rod feeding component 4 includes a welding rod conveying assembly 41, a material guide assembly 42, and a clamping and feeding assembly 43; the material guide assembly 42 includes a material guide track 421, and a rotating unit 422 arranged at the end of the material guide track 421; the clamping and feeding assembly 43 includes a clamping unit 431, a lifting unit 432 for driving the clamping unit 431 to perform a lifting action, and a translation unit 433 for driving the clamping unit 431 to perform a translation action. Specifically, the welding rod conveying assembly 41 includes a vibrating conveying disc and a buffer unit arranged below the material guide track 421. The welding rod is conveyed to the material guide track 421 by the vibrating conveying disc, and the buffer unit absorbs the vibration impact generated by the vibrating conveying disc, so that the welding rod is continuously conveyed to the material guide track 421 and provides a certain conveying thrust. In this way, the welding rod conveying assembly 41 conveys the welding rod to the material guide track 421 and continues to push the welding rod to move toward the end of the material guide track 421, the rotating unit 422 changes the horizontally placed welding rod to a vertical position, the clamping unit 431 clamps the welding rod, the lifting unit 432 drives the clamping unit 431 to perform a lifting action, and the translation unit 433 drives the clamping unit 431 to perform a translation action, thereby conveying the welding rod to the sealing circle edge of the sealing end 103.

[0051] In one embodiment, the rotating unit 422 includes a rotating cylinder 423 and a rotating block 424 arranged at the output end of the rotating cylinder 423; the rotating block 424 is provided with an insertion blind hole; in this way, after the welding rod passes through the material guide track 421, the front end of the welding rod is inserted into the insertion blind hole, and the rotating cylinder 423 drives the rotating block 424 to rotate, and the welding rod changes from a horizontal placement state to a vertical placement state.

In this way, the lifting component 61 drives the high-frequency welding component 62 to perform an ascending action, and when the rotating component 12 drives the temperature-sensing tube 100 on the welding workbench 13 to rotate to the welding station, the lifting component 61 drives the high-frequency welding component 62 to perform a descending action, and the welding coil 601 is inserted into the sealing end 103, and the welding coil 601 heats and melts the sealing edge, thereby sealing and connecting the sealing end 103 and the welding rod.

[0053] In one embodiment, the unloading component 7 includes an unloading lifting assembly 71 disposed on the fixed base 11, an unloading rotating assembly 72 disposed on the unloading lifting assembly 71, and a clamping unloading assembly 73 disposed at the output end of the unloading rotating assembly 72; the clamping unloading assembly 73 includes a first clamping unit 74 for clamping the temperature-sensitive tube 100, and a second clamping unit 75 for clamping the capillary. In this way, the temperature-sensitive tube 100 and the capillary are clamped and fixed by the first clamping unit 74 and the second clamping unit 75, respectively, so that the power member that completes the welding action is clamped and fixed, the clamping assembly 141 releases the clamping action of removing the clamping assembly 141, the unloading lifting assembly 71 drives the clamping unloading assembly 73 to move downward, and the unloading rotating assembly 72 drives the clamping unloading assembly 73 to rotate 90 degrees, so that the power member that completes the welding action is converted from a vertical state to a horizontal state, and the clamping unloading assembly 73 releases the power member, thereby completing the unloading action.

[0054] In one embodiment, the material clamping component 14 further includes an overhead component 15; the material clamping component 141 includes a positioning seat 142 with a clamping groove, a clamping block 143 disposed on the positioning seat 142, and a clamping spring that presses the clamping block 143 toward the clamping groove, and the clamping groove and the inner side surface of the clamping block form a clamping space for clamping the temperature sensing tube 100. In this way, the overhead component 15 presses the clamping spring to keep the clamping block 143 away from the clamping groove, thereby realizing the loading or unloading action of the power piece.

[0055] In one embodiment, the clamping block 143 is provided with a guide column, the positioning seat 142 is provided with a guide hole adapted to the guide column, the guide column is provided with a column head end for pressing the clamping spring, one end of the clamping spring presses the positioning seat 142, and the other end presses the column head end, so that the clamping block 143 is close to the clamping groove.

[0056] In a specific embodiment, the top assembly 15 includes a top cylinder and a top plate driven by the top cylinder. In this way, the top cylinder drives the top plate to press toward the column head end, and the clamping spring is compressed to make the clamping block 143 away from the clamping groove, thereby realizing the loading action or unloading action of the power piece.

[0057] In one embodiment, the welding device 2 further includes a detection component 8, which includes a loading detection component and a reflow detection component; the loading detection component is arranged in front of the welding rod feeding component 4, and is used to detect whether the clamping component 141 is clamped with a temperature-sensitive tube 100; the reflow detection component is arranged behind the unloading component 7, and is used to detect whether the clamping component 141 is clamped with a power part that completes the welding action. In this way, the loading detection component detects whether the clamping component 141 is clamped with a temperature-sensitive tube 100 in front of the welding rod feeding component 4, so as to avoid the clamping component 141 running empty; the reflow detection component detects whether the clamping component 141 is clamped with a power part that completes the welding action behind the unloading component 7, so as to avoid the unsuccessful unloading of the unloading component 7, which causes the clamping component 141 to clamp a power part to perform a cyclic action. Specifically, only when the loading detection component detects that the clamping component 141 clamps the temperature sensing tube 100 and the reflux detection component detects that the clamping component 141 does not clamp the power part, the rotating component 12 will receive the driving signal to drive the welding workbench 13 to rotate, thereby causing the clamping component 141 to perform a cyclic action.

[0058] In one embodiment, the sealing end 103 includes a limiting inner convexity arranged in the sealing rim. Specifically, before the temperature-sensing cylinder 100 welded with the liquid-filled tube is clamped to the material clamping assembly 141 or before the welding rod feeding component 4, the sealing rim of the sealing end 103 is processed by the limiting forming component to form a limiting inner convexity. In this way, the sealing rim forms a socket adapted to the welding rod, and the limiting inner convexity protrudes from the inner wall of the sealing rim, i.e., the socket, to form a bulge, thereby limiting the depth of the welding rod inserted into the sealing end 103, and preventing the welding rod from falling into the cylinder body 101 when the welding rod is pushed into the sealing end 103 in the next step.

[0059] On the one hand, a power component liquid filling pipe sealing welding process in an embodiment of the present invention is applied to a power component liquid filling pipe sealing welding device, comprising the following steps:

[0060] S1. Clamp the material onto the clamping assembly, and the rotating component drives the welding workbench to rotate;

[0065] S6. The unloading component removes the welded power parts from the clamping assembly.

[0066] In this way, by improving the sealing welding process of the power component filling tube, a sealing round edge is set at the sealing end to replace the manual operation of adding welding wire to the temperature sensing tube, the production steps of the welding process are reduced, the production difficulty is reduced, and the production quality is improved.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
