DETAILED DESCRIPTION

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

[0034] Please refer to Figure 1-8 ;

[0035] The material sheet described in the present invention can be made of a metal sheet with a smaller width than that in the prior art, which greatly saves production costs; it is also made by stamping in the production process, specifically including a connecting sheet 11 and a connecting sheet 21 arranged in parallel, with a plurality of connecting ribs 3 connected between the two, and the relative positions of the connecting sheet 11 and the connecting sheet 21 are fixed by the connecting ribs 3; a plurality of electrodes 12 are arranged on the inner side of the connecting sheet 11, and a plurality of electrodes 22 are arranged on the inner side of the connecting sheet 21, and the electrodes 12 and the electrodes 22 correspond to each other and are staggered and close to the opposite connecting sheet. The one-to-one pair referred to in this embodiment It should mean that one electrode 12 and one electrode 22 form a group. Although the electrode 12 and the electrode 2 22 are staggered at this time, they are matched one by one when used, and the center line between the connecting piece 1 11 and the connecting piece 2 21 is used as the boundary. The electrode 1 12 extends toward the connecting piece 2 21, and the electrode 2 22 extends toward the connecting piece 1 11. The lengths of the electrode 1 12 and the electrode 2 22 referred to in this embodiment are the same as those in the prior art. Therefore, the electrode 1 12 and the electrode 2 22 can cross the center line and be as close to the connecting piece 2 21 and the connecting piece 1 11 as possible, respectively, so that the space of the formed sheet is greatly reduced;

[0036] In other words, metal sheets with smaller widths can be used as production materials. Assuming that the principle requires a metal sheet with a width of 30 mm as the production material, a metal sheet with a width of 20 mm can be used as the production material by adopting the structure of the present invention. It can be seen here that the raw materials are saved by 30%, and the waste generated in the stamping process will also be greatly reduced, which greatly reduces the waste of materials in the production process and saves production costs.

[0037] In the subsequent coil welding process, the connecting rib 3 and the connecting piece 21 need to be cut off before the position of the electrode 22 can be moved. Figure 2 and Figure 3 In this embodiment, one electrode 12 and one electrode 22 form one welding position, and the connecting rib 3 is arranged between the two welding positions. When cutting, the connecting piece 21 is divided into several sections, and each section is connected with one electrode 22, that is, each cutting can only form one welding position, and can only weld one coil;

[0038] Or several welding positions are grouped together, and the connecting rib 3 is arranged between two groups. When cutting, the connecting piece 21 is divided into several sections, each section is connected with several electrodes 22, that is, each cutting can form several welding positions, and multiple coils can be welded.

[0039] The present invention discloses a method for using a displaced ultra-narrow sheet for induction coil welding, referring to Figure 5-Figure 8 , including the above-mentioned dislocated ultra-narrow sheet, the specific steps are as follows:

[0040] S1: Feed the sheet into the welding equipment, wherein the welding equipment is provided with a narrow channel 41 and a wide channel 42 in the same direction, wherein the width of the narrow channel 41 is adapted to the initial state of the sheet, and the width of the wide channel 42 is adapted to the width of the sheet after the coil is welded, and a clamping fixture 5 is provided between the narrow channel 41 and the wide channel 42 to reciprocate between the two. The sheet first enters the narrow sheet, and the connecting piece 2 21 is clamped by the clamping fixture 5. In this embodiment, since the connecting piece 1 11 is not cut, the narrow channel 41 and the wide channel 42 are connected together on one side of the connecting piece 1 11, and the side corresponding to the connecting piece 2 21 has a movable notch for the reciprocating movement of the clamping fixture 5;

[0041] Herein, one embodiment of the clamping fixture 5 is listed, which specifically includes a bearing plate 51 for supporting part of the second connecting piece 21, a guide rod 55 is received around the bearing plate 51, a pressing plate 52 is slidably connected to the guide rod 55, a fixing plate 53 is provided above the pressing plate 52, the fixing plate 53 is fixedly connected to the guide rod 55, a spring 54 is provided between the fixing plate 53 and the pressing plate 52, and a positioning rod 56 is provided at the bottom of the pressing plate 52, the positioning rod 56 can be inserted into the through hole 23 of the second connecting piece 21, and passes through the bearing plate 51;

[0042] Furthermore, an ejection mechanism 67 is also provided, which can specifically be a combination of a cylinder and a push rod, and the pressure plate 52 extends laterally from the supporting plate 51 to correspond to the push rod. During operation, the cylinder drives the push rod to move upward, thereby pushing the pressure plate 52 to compress the spring 54 to move upward, and at the same time, the positioning rod 56 is pulled out from the supporting plate 51, so that the pressure plate 52 and the supporting plate 51 are in an open state, and the material sheet can enter therein. When a certain stroke is reached, the cylinder drives the push rod to move downward, and under the action of the spring 54, the pressure plate 52 moves downward to form a clamping state with the supporting plate 51 to the connecting piece 21, and at the same time, the positioning rod 56 passes through the through hole 23 of the connecting piece 21 to fix it.

[0043] S2: The clamping fixture 5 and the end of the narrow channel 41 form a cutting position 59, and the connecting rib 3 and the second connecting piece 21 are cut off by the cutting mechanism 65, so that the section fixed by the clamping fixture 5 is separated from the connecting piece 1 11 and the second connecting piece 21, and the part fixed by the clamping fixture 5 is separated from the connecting piece 1 11 and the second connecting piece 21;

[0044] There are other implementation methods based on the cutting step. In one embodiment, two cutting assemblies are arranged in the narrow channel 41 in the welding equipment. Before entering the clamping fixture 5, the second connecting piece 21 is cut by the first cutting assembly. At this time, this part is still connected to the first connecting piece 11 through the connecting rib 3, and is driven forward by the connecting piece 11, and then the connecting rib 3 is cut by another cutting assembly; or the connecting rib 3 is cut first, and then the second connecting piece 21 is cut, and the same technical effect can be achieved;

[0045] In another embodiment, the second connecting piece 21 is cut into several small segments in advance when the sheet is stamped and formed, and the several small segments are connected to the first connecting piece 11 through the connecting rib 3 to maintain the continuity of the sheet;

[0046] S3: The clamping fixture 5 drives the separation section to move. The bottom of the clamping fixture 5 is provided with a moving mechanism that drives it to move. Specifically, it can be two small electric push rods distributed at 90°, or refer to the relevant structural principles of the Chinese public patent document "CN21463008U, a manipulator that can rotate 90 degrees". Finally, the clamping fixture 5 is transitioned from one end of the narrow channel 41 to one end of the block channel, so that the electrode 2 22 on the separation section is horizontally aligned with the electrode 1 12 on the connecting sheet 1 11. At this time, at least one welding position is formed, which is no different from the welding position formed by the sheet in the prior art.

[0047] After the welding is completed, the connecting piece 11 and the cut part are reconnected with the help of the coil as a connecting medium. After the clamping fixture 5 is reopened, it can drive the whole to move forward. Finally, under the action of the excitation mechanism, the clamping fixture 5 returns to one end of the narrow channel 41.

[0048] The use method of the present invention is customized for the dislocated ultra-narrow sheet, meeting the special distribution requirements of the electrode 1 12 and the electrode 2 22, and realizing industrialized daily production.

[0049] The present invention is further described with respect to welding equipment;

[0050] Specifically, it includes a support seat 61 for carrying the sheet, and a coaxially distributed narrow channel 41 and a wide channel 42 are provided on the support seat 61. On one side of the connecting piece 21, an "L"-shaped limit bar hole 62 is provided on the support seat 61. The limit bar hole 62 is set at the notch and is used to limit the range of movement of the clamping fixture 5. A small mobile platform 63 is connected to the bottom of the clamping fixture 5. Driven by the small mobile platform 63, the clamping fixture 5 slides along the "L"-shaped track and shuttles between the narrow channel 41 and the wide channel 42. The moving distance end of the clamping fixture 5 in the present invention has high precision requirements, so the small mobile platform 63 in this embodiment can use a cross micro linear motor module with a maximum stroke of 50mm;

[0051] The clamping jig 5 clamps the connecting piece 21 and then cuts it. The cutting mechanism 65 used in this embodiment is the same as the prior art, only the size and shape of the cutter are changed, and then the clamping jig 5 is driven by the small mobile platform 63 to move along the "L" track, that is, the track adapted to the limit bar hole 62. The clamping jig 5 moves from one end of the narrow channel 41 to one end of the wide channel 42, so that the electrode 22 and the electrode 1 12 correspond to each other, and then the coil is placed and the lead wire of the coil is connected and fixed to the electrode 1 12 and the electrode 2 22 respectively using the welding assembly 64. At this time, the cut connecting piece 21 and the connecting piece 1 11 are reconnected together through the coil. After the welding is completed, the clamping fixture 5 releases the connecting piece 21, and then the conveying mechanism 66 can drive the connecting piece 1 11 and the connecting piece 21 to move along the wide channel 42, and finally the small mobile platform 63 drives the clamping fixture 5 to reset; the conveying mechanism 66 in this embodiment can be a combination of a cylinder, a fixing frame and a pin, and the pin is inserted into the through hole 23 of the connecting piece 1 11 and the connecting piece 2 21, and then pushed forward by the cylinder; the clamping fixture 5 is further described below;

[0052] Specifically, it includes a bearing plate 51, a fixed plate 53 is connected to the upper side of the bearing plate 51 through a plurality of guide columns, a pressing plate 52 is movably connected to the guiding column, a spring 54 is arranged between the pressing plate 52 and the fixed plate 53, a movable column 57 passing through a limit bar hole 62 is arranged at the bearing bottom, a movable plate 58 is connected to the movable column 57, one side of the pressing plate 52 horizontally extends out of the end face of the support seat 61, and its protruding part corresponds to the ejection mechanism 67. Since the movement stroke of the pressing plate 52 is very short, the ejection mechanism 67 used in this embodiment can be a small electric push rod, and the specific implementation method of moving from one end of the narrow channel 41 to one end of the wide channel 42 is the same as that mentioned above, which is not repeated here, and this embodiment is described with respect to the reset process;

[0053] In this embodiment, one side of the pressure plate 52 horizontally extends out of the end face of the support seat 61, and the lower end face of the protruding part is a plane. A flat plate is provided at the output end of the ejection mechanism 67, and the flat plate and the lower end face of the pressure plate 52 are parallel to each other. Therefore, when the clamping fixture 5 is in a moving state, the two produce relative friction, which can achieve that the clamping fixture 5 still keeps the carrier plate 51 and the pressure plate 52 in an open state during the resetting process, so that the connecting piece 21 can enter therein; of course, in order to make it smoother, a corresponding "L"-shaped track, etc. can be provided on the lower end face of the pressure plate 52.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementations that can be understood by those skilled in the art.
