Description

Technical Field

[0001] This invention relates to the field of coil welding technology, and in particular to a welding apparatus for coils. Background Technology

[0002] A coil is a spiral structure formed by winding conductive materials (such as copper or aluminum wire) on an insulating frame, iron core, or magnetic core in a certain pattern. In the actual production and processing, the coil undergoes winding, shaping and fixing, end stripping, and terminal connection. In order to ensure a stable connection between the coil and the terminal, a welding device is used for the process.

[0003] Existing welding equipment generally requires the use of a pre-stripping device to remove the insulation jacket from the coil connection end. The two are independently distributed, which increases the actual processing and transportation costs. At the same time, the coil is usually manually placed and calibrated before contacting the terminal for welding. For the needs of large-scale production, it is difficult to perform positioning and calibration conveniently. The manual labor intensity is high and it is easy to cause accidental bending of the pins. The overall welding efficiency is generally low. Summary of the Invention

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0037] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a welding device for coils. The welding device for coils includes a bearing component 1, a feeding component 2, and a fixing component 3. By setting the feeding component 2, multiple positioning can be performed in advance during the calibration and alignment process. As the alignment action proceeds, a straightening operation is performed to ensure the accuracy of subsequent welding. At the same time, the initial wire cutting operation is completed. As the alignment action further proceeds, a stripping operation is actively performed after the secondary wire cutting is completed. The degree of manual intervention is small, the operation is quick and convenient, and the processing cost is low. There is no need to add wire stripping equipment or bear the secondary transfer cost.

[0038] Specifically, the supporting component 1 includes a worktable 11, a first electric push rod 12 is provided on the top of the worktable 11, and a welded part 12-1 is fixed to the output end of the first electric push rod 12.

[0039] The welding component 12-1 includes a horizontal plate fixed to the output end of the first electric push rod 12 and multiple welding heads fixed to the bottom of the horizontal plate. Under the drive of the first electric push rod 12, the multiple welding heads will gradually move downward.

[0040] Specifically, the feeding assembly 2 is located on the top of the workbench 11 and includes a feeding seat 21 slidably connected to the top of the workbench 11. A lower mold base 21-5 is fixed to one side of the feeding seat 21. A second electric push rod 22 is fixed to the top of the workbench 11. A guide 23 is fixed to the top of the workbench 11. A positioning component 24 is provided on the feeding seat 21. A processing component 25 is provided on the feeding seat 21, including a movable rod 25-1 rotatably connected to the feeding seat 21. A support plate 25-2 is fixed to the outer ring of the movable rod 25-1. A movable frame 25-3 is fixed to one side of the support plate 25-2. An upper mold base 25-4 is fixed to the bottom of the movable frame 25-3. Displacement bars 25-5 are slidably connected to both the upper mold base 25-4 and the lower mold base 21-5. A peeling component 25-6 is provided on one side of both the upper mold base 25-4 and the lower mold base 21-5. A coil body 26 is placed inside the feeding seat 21.

[0041] By setting the positioning component 24, multiple coil bodies 26 can be positioned simultaneously during the advancement of the second electric push rod 22, so as to ensure the stability of the subsequent actions of the coil bodies 26.

[0042] Specifically, the fixing component 3 is set on the top of the workbench 11, including a fixing seat 31 fixed to the top of the workbench 11, a terminal body 32 is placed in the fixing seat 31, and a placement groove 31-1 is opened in the fixing seat 31 and slidably connected to the terminal body 32.

[0043] Multiple terminal bodies 32 can be stored and positioned through the placement slot 31-1. Since the terminal body 32 has a regular shape and a certain degree of hardness, it can be easily aligned and placed into the placement slot 31-1 during placement. Example 2

[0044] Reference Figures 2 to 12 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0045] Specifically, storage frames 21-1 are fixed on both sides of the feeding seat 21, a material groove 21-2 is opened on the top of the feeding seat 21, a horizontal groove 21-3 is opened on one side of the feeding seat 21, an auxiliary groove 21-4 is opened inside the feeding seat 21, a pressing seat 22-1 is fixed at the output end of the second electric push rod 22, and coil pins 26-1 are fixed at both ends of the coil body 26.

[0046] The guide 23 includes a toothed plate 23-1 fixed on the worktable 11, and a protruding rod 23-2 is fixed at one end of the toothed plate 23-1.

[0047] The positioning component 24 includes a first slider 24-1 that is slidably connected in the transverse groove 21-3. A displacement plate 24-2 is slidably connected to one side of the first slider 24-1. A connecting rod 24-3 is rotatably connected to the displacement plate 24-2. A positioning head 24-4 is rotatably connected to the other end of the connecting rod 24-3.

[0048] As shown in the attached diagram of the instruction manual. Figure 7 As shown, the first slider 24-1 has an inclined side, and one end of it passes through the storage frame 21-1 and slides into contact with the pressure seat 22-1. When the pressure seat 22-1 slides, it will contact the inclined side of the first slider 24-1 and press against the first slider 24-1 to cause displacement.

[0049] A first spring 24-11 is fixed on one side of the first slider 24-1, and the other end of the first spring 24-11 is fixed in the transverse groove 21-3. The connection between the connecting rod 24-3 and the auxiliary groove 21-4, and the connection between the positioning head 24-4 and the auxiliary groove 21-4 are slidably connected. A second spring 24-5 is fixed on one side of the displacement plate 24-2, and the other end of the second spring 24-5 is fixed on the feeding seat 21.

[0050] The first spring 24-11 can keep the first slider 24-1 partially placed inside the storage frame 21-1 without the action of external force.

[0051] The second spring 24-5 provides an elastic connection force to the displacement plate 24-2, keeping the displacement plate 24-2 close to the feed seat 21 when no external force is applied, so that the positioning head 24-4 retracts into the auxiliary groove 21-4 under the connection of the connecting rod 24-3; similarly, when the displacement plate 24-2 moves away from the feed seat 21, the positioning head 24-4 will gradually extend.

[0052] A gear 25-11 is fixed to the outer ring of the movable rod 25-1 and meshes with the toothed plate 23-1. A second slider 25-51 is fixed to one end of the displacement bar 25-5, and a third spring 25-52 is sleeved on the second slider 25-51.

[0053] Auxiliary seats 25-31 are fixed on one side of both the movable frame 25-3 and the feeding seat 21. One end of the second slider 25-51 passes through the auxiliary seat 25-31 and is slidably connected to the auxiliary seat 25-31. One end of the third spring 25-52 is fixed on the second slider 25-51, and the other end of the third spring 25-52 is fixed on the auxiliary seat 25-31.

[0054] By using gear 25-11 and toothed plate 23-1, as gear 25-11 gradually moves, the fixed toothed plate 23-1 can make gear 25-11 rotate, thereby driving the movable rod 25-1 to rotate.

[0055] The upper mold base 25-4 and the lower mold base 21-5 work together to position and store the coil pins 26-1.

[0056] In its initial state, the second slider 25-51 protrudes from the protruding rod 23-2, and one side of the second slider 25-51 is inclined, as shown in the attached diagram of the instruction manual. Figure 8As shown, when the second slider 25-51 moves along with the feeder 21, the guide 23 will contact the inclined surface of the second slider 25-51, so that the second slider 25-51 will be squeezed and move inward automatically.

[0057] The third spring 25-52 provides elastic support for the second slider 25-51, preventing the second slider 25-51 from shifting arbitrarily.

[0058] The auxiliary seat 25-31 can be used to position and guide the movement of the second slider 25-51, thereby improving the displacement stability of the second slider 25-51.

[0059] The coil body 26 includes two semi-circular cutters 25-61 that are rotatably connected to the upper mold base 25-4 and the lower mold base 21-5 respectively. A support rod 25-62 is fixed on the displacement bar 25-5. A guide block 25-68 is fixed to one end of the support rod 25-62. A movable bar 25-63 is rotatably connected between the semi-circular cutter 25-61 and the displacement bar 25-5.

[0060] Both the upper mold base 25-4 and the lower mold base 21-5 are provided with a discharge roller 25-64 on one side. The discharge roller 25-64 has a guide groove 25-65 and is slidably connected to the guide block 25-68. Both ends of the discharge roller 25-64 are rotatably connected to an auxiliary frame 25-66. The auxiliary frame 25-66 is fixed at the connection between the upper mold base 25-4 and the lower mold base 21-5. Both ends of the discharge roller 25-64 are fitted with a torsion spring 25-67. One end of the torsion spring 25-67 is fixed to the discharge roller 25-64, and the other end of the torsion spring 25-67 is fixed to the auxiliary frame 25-66.

[0061] The semi-circular cutter 25-61 protrudes from the outer ring of the coil pin 26-1. That is, after the upper mold base 25-4 and the lower mold base 21-5 are fully engaged, the guide block 25-68 will pierce into the insulating sleeve of the coil pin 26-1 to achieve the initial cutting effect.

[0062] As the displacement bar 25-5 moves, the semi-circular cutter 25-61 will rotate at a certain angle under the connection of the movable bar 25-63, which is used to perform secondary cutting at the connection between the two semi-circular cutters 25-61, ensuring that the insulating sleeve on the coil pin 26-1 can be disconnected properly.

[0063] When the displacement bar 25-5 moves, the support rod 25-62 moves synchronously, and then the guide block 25-68 cooperates with the guide groove 25-65 to make the discharge roller 25-64 actively and slowly rotate forward. The torsion spring 25-67 stores energy. Therefore, when the second slider 25-51 passes through the protrusion 23-2 and no longer contacts the protrusion 23-2, the third spring 25-52 elastically supports the displacement bar 25-5 to quickly reset, and the torsion spring 25-67 releases synchronously. This not only makes the displacement bar 25-5 move quickly, but also links the discharge roller 25-64 to quickly reverse, and discharges the cut insulation sleeve.

[0064] The coil body 26 is actually equipped with an insulating frame, iron core or magnetic core for winding and forming. The positioning head 24-4 is placed in the inner hole of the insulating frame, iron core or magnetic core to complete the positioning operation, and will not cause friction damage to the coil body 26 itself.

[0065] In use, the operator places the coil body 26 into the material trough 21-2 without worrying about the inclination angle of the coil pins 26-1, simplifying the placement operation. Then, the operator controls the second electric push rod 22 to extend and drive the pressure seat 22-1 to slide within the storage frame 21-1 until the pressure seat 22-1 contacts the storage frame 21-1. As the second electric push rod 22 continues to extend, it can drive the feeding seat 21 to move closer to the fixing component 3, so that the coil pins 26-1, after calibration and wire stripping, are placed into the placement groove 31-1 and aligned with the terminal body 32. At this time, the operator controls the first electric push rod 12 to extend and perform welding processing by the welding component 12-1.

[0066] During the above process, when the pressing seat 22-1 slides within the storage frame 21-1, it will first contact the first slider 24-1 and squeeze the first slider 24-1. The first spring 24-11 is compressed to push the displacement plate 24-2 away from the feeding seat 21. The second spring 24-5 is stretched. With the cooperation of the connecting rod 24-3, the positioning head 24-4 is placed in the center of the coil body 26, which can position the coil body 26.

[0067] As the second electric push rod 22 extends further, causing the feed seat 21 to shift as a whole, the engagement of the gear 25-11 and the toothed plate 23-1 causes the movable rod 25-1 to drive the support plate 25-2 to rotate. This, in conjunction with the upper mold base 25-4, can move the coil pin 26-1, causing the coil body 26 to rotate around the positioning head 24-4 until the coil pin 26-1 is positioned between the upper mold base 25-4 and the lower mold base 21-5.

[0068] When the upper mold base 25-4 rotates and closes, the semi-circular cutter 25-61 will perform preliminary cutting on the insulating sleeve on the coil pin 26-1.

[0069] After the upper mold base 25-4 is rotated and closed, the gear 25-11 and the toothed plate 23-1 no longer mesh. At this time, when the feed seat 21 continues to move, the second slider 25-51 will contact the protrusion 23-2, causing the displacement bar 25-5 to move. In conjunction with the movable bar 25-63, the semi-circular cutter 25-61 rotates at a certain angle to complete the secondary cutting process, ensuring that the insulating sleeve can be easily removed.

[0070] During the secondary cutting operation, the guide block 25-68 and the guide groove 25-65 cooperate to make the discharge roller 25-64 rotate slowly. The torsion spring 25-67 stores energy. After the secondary cutting is completed, the second slider 25-51 passes over the protrusion 23-2. At this time, with the cooperation of the torsion spring 25-67 and the third spring 25-52, the discharge roller 25-64 can rotate quickly to discharge the separated insulating sleeve. Example 3

[0071] Reference Figures 4 to 12 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0072] Specifically, see the attached diagram in the instruction manual. Figure 7 As shown, the storage frame 21-1 has a through groove on its side to meet the space requirements of the first slider 24-1. The pressing seat 22-1 is L-shaped. While meeting the connection with the output end of the second electric push rod 22, it can pass through the storage frame 21-1 and slide to connect with the storage frame 21-1. This not only ensures the displacement stability of the pressing seat 22-1, but also prevents the pressing seat 22-1 from detaching from the storage frame 21-1 when it retracts excessively.

[0073] As shown in the attached diagram of the instruction manual. Figure 7 and Figure 9 As shown, a crossbar is fixed to the inner wall of the transverse groove 21-3. The crossbar passes through the first slider 24-1 and is slidably connected to the first slider 24-1 to improve the stability of the first slider 24-1's movement. The first spring 24-11 is sleeved on the crossbar to prevent the first spring 24-11 from bending and deforming arbitrarily.

[0074] One end of the movable rod 25-1 is rotatably connected to the feed seat 21 via a damping bearing. With this design, the movable rod 25-1 can be kept at the corresponding angle by utilizing the friction of the damping bearing without the action of external force.

[0075] As shown in the attached diagram of the instruction manual. Figure 10 As shown, the part of the displacement bar 25-5 embedded in the lower mold base 21-5 has a T-shaped design. This design can ensure the stability of the movement of the displacement bar 25-5 and prevent the displacement bar 25-5 from detaching from the lower mold base 21-5; similarly, it can also prevent the displacement bar 25-5 from detaching from the upper mold base 25-4.

[0076] The top of the workbench 11 is provided with a material drop chute 11-1, the bottom of the workbench 11 is bolted to a collection box 11-2, the top of the workbench 11 is fixed with a support frame 12-2, and the first electric push rod 12 is bolted to the top of the support frame 12-2.

[0077] The inner diameter of the collection box 11-2 is larger than the inner diameter of the drop chute 11-1. The collection box 11-2 can collect the insulating sleeves that fall through the drop chute 11-1 after cutting, which is beneficial for subsequent centralized processing.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
