[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] To more clearly express the purpose of this invention and the technical solutions of its embodiments, this invention is placed on a horizontal plane, with the direction perpendicular to the horizontal plane being the vertical direction, the upper part being the top, and the lower part being the bottom.

[0035] As shown in the figure, this utility model discloses a strip soldering connection fixture, including a detachably connected base 1 and a top cover 2. A first strip 31 and a second strip 32 are arranged overlappingly between the base 1 and the top cover 2. Both the first strip 31 and the second strip 32 have positioning holes 34. The base 1 and / or the top cover 2 are provided with a plurality of conical teeth 11 corresponding to the positioning holes 34. The top cover 2 is provided with a hollowed-out welding window 21. At least a portion of the overlap 33 of the first strip 31 and the second strip 32 is disposed in the welding window 21. A welding rod passes through the welding window 21 to weld the first strip 31 and the second strip 32 of the overlap 33, so that the two are integrated into a single structure and the length of the strip 3 is extended.

[0036] The connecting fixture can be used in conjunction with a winding machine and is located at the feed end of the winding machine.

[0037] In existing technology, the material strip 3 is placed on a conveyor table and fed to a winding machine. Then, hollow coils made of wire are welded one by one into the material strip 3 using a welding machine. During the process of conveying the material strip 3 to the winding machine on the conveyor table, because the material strip 3 is divided into multiple segments and the length of each segment is limited, it cannot be guaranteed that the winding machine can continuously convey the material strip 3 without stopping. The operation of the winding machine must be paused and another segment of material strip is put in. This repeated stopping and starting of the winding machine accounts for too large a proportion of the production time, resulting in the technical problem of low machine production efficiency. However, with the material strip soldering connection fixture of this application, it is only necessary to use the connection fixture to connect and fix the two material strips before the material strip 3 is conveyed to the winding machine. The operator or the robot arm can then use the soldering rod to solder the overlapping part 33. The fixture can then be disassembled in the vertical direction, so that the first material strip 31 and the second material strip 32 can be integrated into a single structure and the material strip can be lengthened. The whole operation process is very simple and quick, allowing the winding machine to be continuously fed with material strips without stopping, greatly improving the machine production efficiency.

[0038] Specifically, in one embodiment of this utility model, the strip 3 is provided with two rows of positioning holes 34, which are circular in shape. The two rows of positioning holes 34 are placed symmetrically along the central axis L and arranged in sequence with the same spacing. Both the first strip 31 and the second strip 32 are provided with welding holes 35 for welding.

[0039] Furthermore, the overlapping area of ​​the material strip overlap 33 is smaller than the surface area of ​​the base 1 and slightly larger than the area of ​​the welding window 21. The overlapping area includes four positioning holes 34, two on each side of the axis L. The main location for soldering is the welding hole 35 in the overlapping area. If the overlapping area only includes two positioning holes 34, one on each side, after the soldering connection is completed, it cannot be guaranteed that the first material strip 31 and the second material strip 32 have a good fixing effect, especially in the vertical direction, which is prone to loosening, and will affect the production effect of the subsequent conveying and winding machine.

[0040] Specifically, in one embodiment of this utility model, the welding window 21 in the upper cover 2 is elongated and extends vertically, with the long side of the elongated shape perpendicular to the axis L. That is, the width of the welding window 21 is greater than the width of the strip 3, so that the operator can solder the overlapping part 33 of the strip through the welding window 21.

[0041] Specifically, in one embodiment of this utility model, the upper cover 2 and / or the base 1 are provided with a clearance portion 4, and the material strip 3 is disposed in the clearance portion 4. This structural design can cooperate with the conical teeth 11 to make the material strip 3 snap between the base 1 and the upper cover 2, avoiding wear on the base 1 and / or the upper cover 2 due to long-term use. In the connecting fixture, the clearance portion 4 is mainly disposed in the upper cover 2, corresponding to the material strip 3. At the same time, the clearance portion 4 can also be disposed in the base 1, or part of it can be disposed in the base 1 and the other part can be disposed in the upper cover 2, which can also achieve the effect of fixing and snapping the material strip 3.

[0042] Specifically, in one embodiment of this utility model, the surface of the base 1 is provided with a plurality of conical teeth 11. The conical teeth 11 can help the operator to accurately position and fix the strip 3. When the strip 3 is placed on the base 1, the conical teeth 11 can be embedded in the positioning hole 34 to ensure that the strip 3 remains stable during the soldering process. At the same time, the conical teeth 11 can also be set in the upper cover 2 to correspond to the positioning hole 34 on the strip 3, which can also achieve the effect of fixing the strip 3.

[0043] Furthermore, the upper cover 2 is provided with a clearance hole 22 corresponding to the conical tooth 11. This structural design allows the conical tooth 11 to remain embedded in the clearance hole 22 after passing through the positioning hole 34 in the material strip 3, thereby fixing the material strip 3 and the upper cover 2 in sequence. At the same time, if the upper cover 2 is provided with the conical tooth 11, the clearance hole 22 can also be provided on the surface of the base 1 to achieve the same effect.

[0044] Specifically, in one embodiment of this utility model, at least a portion of the conical teeth 11 are disposed on the base 1 and corresponding to the welding window 21. Since the welding rod passes through the welding window 21 of the upper cover 2 to solder the strip 3, the conical teeth 11 cannot be installed at the position of the welding window 21. That is, only a portion of the conical teeth 11 corresponding to the welding window 21 can be installed on the base 1. The specific number of the portion of the conical teeth 11 depends on the size of the welding window 21.

[0045] Specifically, in one embodiment of this utility model, the base 1 and / or the upper cover 2 have eight conical teeth 11, symmetrically placed along the central axis L of the strip 3, with four on each side. The distance between the conical teeth 11 on both sides and the central axis L varies with different strip models. The placement of the conical teeth 11 corresponds to the positioning holes 34. The four conical teeth 11 in the middle area correspond to the four positioning holes 34 of the overlapping part 33. The function of the four conical teeth 11 in the outer area is to ensure that the first strip 31 and the second strip 32 can maintain a straight line along the central axis L during soldering. Increasing the number of conical teeth 11 in the outer area can further improve the effect of keeping the strip 3 in a straight line, but it will increase the production cost of the strip soldering connection fixture and prolong the operation time. Considering all factors, the number of eight conical teeth 11 and their placement are most suitable.

[0046] Furthermore, the conical tooth 11 has a conical top 111 that gradually extends downwards to the middle of a first cylinder 112, and continues downwards to the bottom of a larger diameter cylinder 113. The function of the conical top 111 is to facilitate the operator in more easily aligning the positioning holes 34 in the material strip 3 with the conical tooth 11. If the shape of the conical top 111 is cylindrical, and there are 8 positioning holes 34 that need to be inserted, it will greatly prolong the alignment time, lengthen the operation time, and affect production efficiency. After passing through the top 111 of the cone from top to bottom, the hole 34 reaches the middle 112 of the first cylinder. The diameter of the middle 112 of the first cylinder is equal to the diameter of the positioning hole 34, which further fixes the material strip 3 in the horizontal direction. Only part of the middle 112 of the first cylinder and the top 111 of the cone are exposed on the surface of the base 1, while the other part of the middle 112 of the first cylinder and the bottom 113 of the cylinder are fixed inside the base 1, so that the conical teeth 11 are completely fixed in the vertical and horizontal directions.

[0047] Specifically, in one embodiment of this utility model, the base 1 is provided with a guide post 12. The guide post 12 includes a hemispherical top 121, gradually extending downward to the middle 122 of a second cylinder, and continuing downward to the bottom 123 of a hemispherical structure. This hemispherical structure design allows the guide post 12 to be accurately aligned with the corresponding hole. The base 1 is provided with a cylindrical hole 13 for installing the guide post 12. The cylindrical hole 13 is a cylinder located inside the base 1, extending upward to the surface of the base 1 but not downward. During assembly, the guide post 12 is simply aligned with the cylindrical hole 13 and pushed towards the bottom of the base 1 to complete the assembly. This exposes a portion of the middle 122 of the second cylinder and the top 121 of the hemispherical structure on the surface of the base 1. The diameter of the middle 122 of the second cylinder is slightly larger than the diameter of the cylindrical hole 13, creating an interference fit, thus fixing the guide post 12 in the base 1.

[0048] Furthermore, the upper cover 2 is provided with a guide hole 23 corresponding to the guide post 12. The guide hole 23 is cylindrical in shape and runs through the top and bottom. Because the size of the guide post 12 is larger than the conical tooth 11, during installation, the operator only needs to align the guide hole 23 into the guide post 12 to complete the connection between the base 1 and the upper cover 2.

[0049] In another embodiment, the guide hole 23 is provided in the base 1 and the guide post 12 is provided in the upper cover 2, which can also achieve the above effect.

[0050] Specifically, in one embodiment of this utility model, at least two guide posts 12 are provided and positioned diagonally on the connecting fixture. The purpose of this structural design is that as long as the operator can align the guide hole 23 into the guide post 12, the width of the welding window 21 can be guaranteed to be greater than the width of the strip 3, and there is no situation of reverse installation, thereby reducing operation time and improving production efficiency.

[0051] Specifically, in one embodiment of this utility model, because the conical tooth 11 is a countersunk pin, the base 1 is provided with a countersunk hole 14 corresponding to the conical tooth 11. The countersunk hole 14 is vertically connected and consists of two parts, which are cylindrical in shape with different diameters and are interconnected. The upper part 141 of the cylindrical hole extends upwards to the surface of the base 1, and the lower part 142 of the cylindrical hole with a larger diameter extends downwards to the bottom surface of the base 1. When assembling the conical tooth 11 onto the base 1, it is only necessary to align the top 111 of the conical tooth with the countersunk hole 14 on the bottom surface of the base 1. The countersunk hole 14 is pushed towards the surface of the base 1. It should be noted that the diameter of the middle part 112 of the first cylinder is slightly larger than the diameter of the upper part 141 of the cylindrical hole, and the diameter of the bottom part 113 of the cylinder is slightly larger than the diameter of the lower part 142 of the cylindrical hole. During the pushing process, an interference fit is generated. Due to the difference in diameter between the two parts, the conical tooth 11 can be engaged in the countersunk hole 14. The middle part 112 of the first cylinder and the top part 111 of the conical body are exposed on the surface of the base 1, so that the conical tooth 11 is fixedly installed in the base 1.

[0052] The working principle of this utility model is explained in detail below:

[0053] During assembly, firstly, the six positioning holes 34 at the end of the first strip 31 are inserted into the six conical teeth 11 in the base 1 near the direction of the first strip 31. The second strip 32 is operated in the opposite direction, so that there are four positioning holes 34 in the overlapping area of ​​the first strip 31 and the second strip 32, and each overlapping positioning hole 34 can be inserted into the same conical tooth 11. Then, the guide hole 23 in the upper cover 2 is inserted into the guide post 12, so that the strip 3 is fixed between the base 1 and the upper cover 2 in both vertical and horizontal directions. Subsequently, the operator or the robotic arm uses a soldering rod to solder the overlapping part 33 of the strip through the soldering window 21 in the upper cover 2. After completion, the upper cover 2 is disassembled vertically upward and the base 1 is vertically downward, so that the strip 3 can be lengthened on the conveyor table, and the winding machine can be continuously conveyed with strip without stopping.

[0054] The innovation of this utility model lies in:

[0055] During the process of conveying the strip onto the winding machine, the strip soldering connection fixture can extend the strip on the conveyor, ensuring that the winding machine is continuously conveyed without stopping. The whole process is simple and easy to operate, and the cost is low. Only an operator or robotic arm, soldering rod, and the strip soldering connection fixture are needed to improve the machine's production efficiency.

This narrative style of the specification is merely for clarity.
