[0020] The following is a detailed description of three implementation methods of the present application in conjunction with the accompanying drawings.

[0021] The first implementation method: The present invention provides a welding plate of a wick automatic welding device, see Figure 1-4 , including a fixed base 1, a rotating disk 2, a heating block 3 and a linkage mechanism.

[0022] Among them, a driving motor 4 is installed at the center of the fixed base 1, and an annular wire-dropping groove 101 with the center of the fixed base 1 as the center is provided at the upper end of the fixed base 1. The rotating disk body 2 is rotatably installed on the upper end of the fixed base 1, and the output end of the driving motor 4 is fixedly connected to the center of the rotating disk body 2. A positioning hole 201 is provided on the rotating disk body 2, and the positioning hole 201 is located just above the wire-dropping groove 101. Two heating blocks 3 are provided at the upper and lower openings of the positioning hole 201. Installation grooves 202 for horizontal sliding installation of the two heating blocks 3 are provided at the upper and lower openings of the positioning hole 201, and the two installation grooves 202 located at the openings on the same side of the positioning hole 201 are symmetrically arranged 180 degrees, wherein the width of the installation groove 202 is greater than the aperture of the positioning hole 201.

[0023] The linkage mechanism is installed between the fixed base 1, the rotating disk 2 and the heating block 3, so that when the driving motor 4 drives the rotating disk 2 to rotate, the two heating blocks 3 located at the same side of the positioning hole 201 move synchronously toward or away from each other.

[0024] The welding disk of the automatic wick welding device is provided with a linkage mechanism. When the driving motor 4 drives the rotating disk body 2 to rotate, the two heating blocks 3 located at the hole openings on the same side of the positioning hole 201 reciprocate and synchronously approach or move away. During the process of the two heating blocks 3 approaching synchronously, the glass tube is heated and squeezed, so that the end part of the glass tube and the copper wire are welded together. After the welding is completed, the two heating blocks 3 move away synchronously, and the material can be unloaded, and the material can be loaded before the two heating blocks 3 approach each other and cross the positioning hole 201, thereby realizing continuous non-stop welding operation, and the upper and lower end parts of the glass tube can be welded at the same time, and the welding efficiency is higher.

[0025] Specifically, Figure 2-Figure 4 It is shown that the linkage mechanism includes a fixed gear ring 5, a moving gear 6, a bidirectional threaded rod 7 and a linkage assembly 8. The fixed gear ring 5 is arranged cocentrically with the output shaft of the driving motor 4, and the fixed gear ring 5 is fixed to the upper end of the fixed base 1. An annular groove matching the fixed gear ring 5 is arranged on the rotating disk body 2. The moving gear 6 is rotatably installed on the inner side of the rotating disk body 2, and the moving gear 6 is meshed with the fixed gear ring 5. The bidirectional threaded rod 7 is horizontally arranged and rotatably installed on the inner side of the installation groove 202. The two heating blocks 3 located at the same side opening of the positioning hole 201 are symmetrically threadedly sleeved on the two ends of the bidirectional threaded rod 7. The two ends of the bidirectional threaded rod 7 are symmetrically provided with bidirectional threads, so that when the bidirectional threaded rod 7 always rotates in the same direction, the two heating blocks 3 located at the same side opening of the positioning hole 201 reciprocate and synchronously approach or move away.

[0026] More specifically, Figure 4 It is shown that the linkage assembly 8 includes bevel gear 1 81, bevel gear 2 82, bevel gear 3 83 and bevel gear 4 84. Bevel gear 1 81 is coaxially fixed with the moving gear 6. Bevel gear 2 82 is rotatably installed on the inner side of the rotating disk body 2 and meshes with bevel gear 1 81. Bevel gear 3 83 is coaxially fixed with bevel gear 2 82. Bevel gear 4 84 is coaxially fixed with the bidirectional threaded rod 7 and meshes with bevel gear 3 83.

[0027] Based on the matching arrangement of the above structure, when the driving motor 4 drives the rotating disk body 2 to rotate, the moving gear 6 rotates under the meshing action with the fixed gear ring 5, thereby driving the bevel gear 1 81 to rotate, and the bevel gear 1 81 drives the bevel gear 3 83 to rotate through the bevel gear 2 82, and the bevel gear 3 83 drives the bidirectional threaded rod 7 to rotate through the bevel gear 4 84. When the bidirectional threaded rod 7 always rotates in the same direction, the two heating blocks 3 located at the same side of the positioning hole 201 move reciprocatingly and synchronously close to or away from each other, thereby realizing the continuous welding operation of the wick.

[0028] Among them, there are multiple positioning holes 201, and the multiple positioning holes 201 are equidistantly distributed on the circumference of the rotating disk body 2 with the center of the rotating disk body 2 as the center of the circle. The appropriate bidirectional threaded rod 7, movable gear 6 and fixed gear ring 5 can be selected according to actual needs. By utilizing the cooperation of the three, the rotating disk body 2 can perform welding operations on multiple wicks at the same time, and the welding efficiency is higher. Only two are taken as examples in the attached figure.

[0029] The ends of the two heating blocks 3 located at the same side of the positioning hole 201 and close to each other are coated with a high-temperature resistant non-stick coating, which can effectively prevent the glass liquid from adhering to the surface of the heating block 3.

[0030] Working principle: the glass tube is placed in the positioning hole 201 by a manipulator, and then the copper wire is placed inside the glass tube, and the bottom end of the copper wire falls into the wire drop groove 101. During the process of the driving motor 4 driving the rotating disk 2 to rotate, the moving gear 6 rotates under the meshing action with the fixed gear ring 5, thereby driving the bevel gear 1 81 to rotate, and the bevel gear 1 81 drives the bevel gear 3 83 to rotate through the bevel gear 2 82, and the bevel gear 3 83 drives the bidirectional threaded rod 7 to rotate through the bevel gear 4 84. When the bidirectional threaded rod 7 always rotates in the same direction, the two heating blocks 3 located at the same side of the hole opening of the positioning hole 201 reciprocate and synchronously approach or move away. During the process of the two heating blocks 3 approaching synchronously, the glass tube is heated and squeezed, so that the port part of the glass tube is welded to the copper wire. After the welding is completed, the two heating blocks 3 move away synchronously, and the manipulator can be used for unloading, and the manipulator can be used for loading before the two heating blocks 3 approach each other to cross the positioning hole 201, so as to realize continuous non-stop welding operation, and the upper and lower port parts of the glass tube can be welded at the same time, and the welding efficiency is higher.

[0031] Second implementation method: This embodiment is based on the embodiment 1, and the following structure is added, so that the present application has the function of uniformly heating the end of the glass tube, and the specific configuration is as follows: Figure 7 As shown, the heating block 3 includes a mounting portion 31, a heating portion 32 and an elastic connecting portion 33. The mounting portion 31 is threadedly sleeved on the outer side of the bidirectional threaded rod 7. A plurality of heating portions 32 and elastic connecting portions 33 are correspondingly arranged, and the plurality of heating portions 32 are respectively connected to the ends of two mounting portions 31 located at the same side openings of the positioning hole 201 through the plurality of elastic connecting portions 33. When the elastic connecting portion 33 is not subjected to external force, the ends of the plurality of heating portions 32 away from the mounting portion 31 form an arc surface that matches the surface of the glass tube.

[0032] Among them, the lengths of the multiple heating parts 32 are the same, and the lengths of the multiple elastic connecting parts 33 are different, so that when the elastic connecting parts 33 are not subjected to external forces, the ends of the multiple heating parts 32 away from the mounting part 31 form an arc surface that matches the surface of the glass tube, ensuring that the end surface of the glass tube is always in contact with the multiple heating parts 32, so that the heating is more uniform and the welding effect is better.

[0033] It should be further explained that the relative sliding limit between the heating parts 32 and the heating parts 32 and between the heating parts 32 and the inner wall of the installation groove 202 ensures that the heating parts 32 can stably reciprocate horizontally.

[0034] The third implementation method: This embodiment is based on the embodiment 1, and the following structure is added, so that the present application has the effect of cooling the welding point, and the specific configuration is as follows: Figure 8 and Fig. 9 As shown, as a further supplement to the present application, an elastic airbag 9 is installed on the inner side of the rotating disk 2, and a pressing block 10 in contact with the elastic airbag 9 is installed on the end of the heating block 3 close to the positioning hole 201; The elastic airbag 9 is provided with an air inlet and an air outlet, both of which are provided with a one-way valve, a first air passage 203 connected to the air inlet is provided on the side of the rotating disc 2 away from the positioning hole 201, and a second air passage 204 connected to the air outlet is provided on the side of the rotating disc 2 close to the positioning hole 201; The opening between the second air passage 204 and the positioning hole 201 is inclined toward one side of the installation groove 202 , and a third air passage 102 communicating with the wire drop groove 101 is provided at the side end of the fixed base 1 .

[0035] Based on the above matching settings, when the two heating blocks 3 located at the openings on the same side of the positioning hole 201 approach each other, the pressure block 10 is moved away from the elastic airbag 9, and the elastic airbag 9 inhales air through the air inlet under the action of its own elastic force to complete the reset expansion. When the two heating blocks 3 located at the openings on the same side of the positioning hole 201 move away from each other, the pressure block 10 is moved closer to the elastic airbag 9, and the elastic airbag 9 is exhausted through the air outlet under pressure. The exhausted airflow takes away the heat from the welding points at both ends of the glass tube, which has a certain cooling effect.

[0036] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
