Description

Technical Field

[0001] This utility model relates to the technical field of copper wire processing equipment, and specifically to a bidirectional positioning mechanism for flat copper wire. Background Technology

[0002] The processing of enameled copper wire involves spraying multiple layers of insulating varnish onto the outer wall of the conductive copper wire, which not only prevents rust but also provides insulation. Enameled copper wire is a major raw material for products such as motors, electrical appliances, and household appliances. In particular, the continuous and rapid growth of the power industry and the rapid development of household appliances in recent years have brought a wide range of applications for enameled copper wire. The stator winding of a flat copper wire motor is made of flat copper wire. During the stator winding manufacturing process, a certain length of insulating varnish needs to be removed from both ends of the flat copper wire. The thickness and length of the varnish removal are required to meet the welding process and electrical performance requirements of the subsequent varnish-removed part of the flat copper wire.

[0003] The positioning accuracy of flat copper wire directly affects the accuracy of enamel removal at its stripping end. If the enamel is not completely removed, problems such as weak welds, incomplete soldering, or insufficient weld strength may occur during soldering. If too much enamel is removed, reaching the copper wire layer, the wire diameter is reduced, leading to decreased conductivity. Existing enamel stripping devices, such as those disclosed in CN 218534190 U, use positioning devices around the flat copper wire, but do not position the ends. Due to the smooth surface of the flat copper wire, it is prone to slippage during the enamel removal process due to the friction of the scraper, thus affecting the stripping accuracy. Furthermore, the relatively soft nature of flat copper wire makes it easy for hard positioning at the ends to damage them, affecting the length and integrity of the stripped end, and consequently the stripping effect. Therefore, ensuring precise positioning and integrity of the stripped end of the flat copper wire is a pressing issue that needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bidirectional positioning mechanism for flat copper wires.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A bidirectional positioning mechanism for flat copper wire includes a fixed connecting block, a top positioning component, and an end positioning component. The bottom of the fixed connecting block is provided with a horizontally extending first limiting groove, and the distal end of the fixed connecting block is provided with a vertically extending second limiting groove. The bottom of the second limiting groove is connected to the top of the first limiting groove. The end positioning component includes a slider and an end positioning cylinder. The slider is slidably disposed in the first limiting groove and is driven by the end positioning cylinder to move horizontally relative to the bottom of the second limiting groove. The distal end of the slider forms a positioning step surface that matches the end of the copper wire with the enamel removed. The top positioning component includes a pressure block and a top positioning cylinder. The pressure block is slidably disposed in the second limiting groove and is driven by the top positioning cylinder to move vertically relative to the positioning step surface. The bottom of the pressure block and the positioning step surface together define the enamel removed end of the copper wire.

[0007] Preferably, the end positioning cylinder is vertically fixed to the top of the fixed connecting block, and its driving end is fixedly connected to a vertically extending connecting rod, which drives the connecting rod to move vertically relative to the proximal end of the slider. The proximal end of the slider has an inclined insertion hole, and the bottom of the connecting rod has an inclined insertion block that matches the inclined insertion hole. The inclined insertion block is inserted into the inclined insertion hole to drive the slider to move horizontally.

[0008] Preferably, the width of the vertical part of the connecting rod is greater than the width of the inclined block, and the fixed connecting block is provided with a guide hole that matches the vertical part of the connecting rod, so that the connecting rod can move vertically along the guide hole.

[0009] Preferably, an end positioning block is detachably fixed to the distal end of the slider, and the top surface of the end positioning block forms the positioning step surface.

[0010] Preferably, the top positioning cylinder is also vertically fixed to the top of the fixed connecting block, and the pressure block is fixed to the driving end of the top positioning cylinder and driven by it to move vertically along the second limiting slide groove.

[0011] Preferably, the cross-section of the second limiting groove is I-shaped, which includes an inner limiting part and an outer limiting part that are connected to each other. The inner limiting part is located inside the fixed connecting block, and the outer limiting part is formed by the inward indentation of the side of the fixed connecting block, and the length of the outer limiting part is greater than that of the inner limiting part.

[0012] Preferably, the pressure block matches the second limiting groove, and a top positioning block is detachably fixed at the bottom of the pressure block, the top positioning block being slidably disposed within the outer limiting portion.

[0013] Preferably, the outer side of the top positioning block is flush with the outer side of the end positioning block, and the bottom of the outer side of the top positioning block has a limiting notch, the inner contour of the limiting notch matches the outer contour of the copper wire, and the width of the limiting notch is smaller than that of the copper wire.

[0014] Preferably, it further includes a mounting connecting block, wherein the fixing connecting block is fixedly disposed on the top of the mounting connecting block, and the mounting connecting block has connecting holes on both sides for connection.

[0015] The beneficial effects of this utility model are mainly reflected in:

[0016] 1. A top positioning mechanism is set to position the vertical position of the copper wire, and an end positioning mechanism that can slide horizontally relative to the top positioning mechanism is set to position the horizontal position of the copper wire. By using the sliding nature of the end positioning mechanism, hard contact between the positioning step surface and the end of the copper wire to remove the enamel is avoided, thus ensuring the integrity of the end of the enamel removal device. At the same time, the horizontal and vertical positions of the copper wire are defined from both the end and top directions to prevent the copper wire from sliding, thereby achieving precise positioning of the end of the copper wire to remove the enamel, in conjunction with the enamel removal device.

[0017] 2. The end positioning blocks and top positioning blocks can be detachably set to adapt to different types of copper wires, improving the flexibility of use and expanding the range of applications;

[0018] 3. The end positioning cylinder uses the inclined insertion block and inclined insertion hole of the connecting rod to convert the vertical movement of the connecting rod into horizontal movement to drive the slider to move, so that the end positioning cylinder can be set on the top of the fixed connecting block to reduce space occupation.

However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0026] like Figures 1 to 4 As shown, this utility model discloses a bidirectional positioning mechanism for flat copper wire, including a fixed connecting block 1, a top positioning component, and an end positioning component. The bottom of the fixed connecting block 1 is provided with a horizontally extending first limiting groove 101, and the distal end of the fixed connecting block 1 is provided with a vertically extending second limiting groove 102, the bottom of the second limiting groove 102 communicating with the top of the first limiting groove 101. The end positioning component includes a slider 301 and an end positioning cylinder 302. The slider 301 is slidably disposed within the first limiting groove 101 and... Driven by the end positioning cylinder 302, the slider 301 moves horizontally relative to the bottom of the second limiting slide groove 102. The distal end of the slider 301 forms a positioning step surface 303 that matches the end of the copper wire 4 with the paint removal end. The top positioning component includes a pressure block 201 and a top positioning cylinder 202. The pressure block 201 is slidably disposed in the second limiting slide groove 102 and is driven by the top positioning cylinder 202 to move vertically relative to the positioning step surface 303. The bottom of the pressure block 201 and the positioning step surface 303 together define the paint removal end of the copper wire 4.

[0027] This solution uses a top positioning mechanism to position the vertical position of the copper wire 4, and an end positioning mechanism that can slide horizontally relative to the top positioning mechanism to position the horizontal position of the copper wire 4. The sliding nature of the slider 301 in the end positioning mechanism prevents hard contact between the positioning step surface 303 and the paint-removing end of the copper wire 4, ensuring the integrity of the paint-removing end. Simultaneously, it limits the horizontal and vertical positions of the copper wire 4 from both the end and top directions, preventing slippage and achieving precise positioning of the paint-removing end of the copper wire 4 to cooperate with the paint-removing device.

[0028] Preferably, the fixed connecting block 1 is a cuboid to minimize its structure, and its axial extension is adapted to the extension direction of the copper wire 4.

[0029] Specifically, the end positioning cylinder 302 is vertically fixed to the top of the fixed connecting block 1. The end positioning cylinder 302 can be directly set on the top of the fixed connecting block 1, or a support frame can be set on the top of the fixed connecting block 1 to fix the end positioning cylinder 302. The driving end of the end positioning cylinder 302 moves vertically. The driving end is fixed to a vertically extending connecting rod 304 and drives the connecting rod 304 to move vertically relative to the proximal end of the slider 301. The proximal end of the slider 301 has an inclined insertion hole 305. The bottom of the connecting rod 304 has an inclined insertion block 3041 that matches the inclined insertion hole 305. The inclined insertion block 3041 is inserted into the inclined insertion hole 305 to drive the slider 301 to move horizontally. The angle of the inclined insertion block 3041 is adapted to the angle of the inclined insertion hole 305 so that the two slide in close contact, thereby enhancing the smoothness of the sliding of the inclined insertion block 3041. The specific angle of the two is determined according to the distance that the slider 301 needs to move.

[0030] Furthermore, the width of the vertical rod portion of the connecting rod 304 is greater than the width of the inclined insertion block 3041, and the fixed connecting block 1 is provided with a guide hole 103 that matches the vertical rod portion of the connecting rod 304, so that the connecting rod 304 moves vertically along the guide hole 103, thereby improving the smoothness of the movement of the connecting rod 304.

[0031] Preferably, the width of the vertical rod portion of the connecting rod 304 is not less than the maximum width of the inclined insertion block 3041, so that a concave portion is formed between the vertical rod portion of the connecting rod 304 and the inclined insertion block 3041, and a convex portion that matches the concave portion is formed at the inclined insertion hole 305 of the slider 301. The concave portion and the convex portion match to form a final limit on the downward movement of the connecting rod 304, so as to avoid excessive downward movement and excessive movement of the slider 301.

[0032] The end positioning cylinder uses the inclined insertion block 3041 and the inclined insertion hole 305 to convert the vertical movement of the connecting rod 304 into horizontal movement to drive the slider 301 to move. This allows the end positioning cylinder 302 to be positioned on top of the fixed connecting block 1, reducing space occupation. The top positioning cylinder 202 is also vertically fixed on top of the fixed connecting block 1. Preferably, the top positioning cylinder 202 and the end positioning cylinder 302 are arranged side by side to optimize the structural layout and reduce space occupation. The pressure block 201 is fixed to the driving end of the top positioning cylinder 202 and is driven by it to move vertically along the second limiting slide groove 102.

[0033] The second limiting groove 102 has an I-shaped cross section and includes an inner limiting part and an outer limiting part that are connected to each other. The inner limiting part is located inside the fixed connecting block 1, and the outer limiting part is formed by the inward recess of the side of the fixed connecting block 1. The length of the outer limiting part is greater than that of the inner limiting part. The pressure block 201 matches the second limiting groove 102.

[0034] To improve the compatibility between the pressure block 201 and the slider 301, an end positioning block 306 is detachably fixed to the distal end of the slider 301. The top surface of the end positioning block 306 forms the positioning step surface 303. The specific length and inner contour of the end positioning block 306 are adapted to the length of the paint-removing end of the copper wire 4. A top positioning block 203 is detachably fixed to the bottom of the pressure block 201. The top positioning block 203 is slidably disposed within the outer limiting part to slide along the inner wall of the outer limiting part. The setting of the outer limiting part limits the position of the top positioning block 203 so that its bottom is directly opposite the end positioning block 306, making the outer surface of the top positioning block 203 flush with the outer surface of the end positioning block 306; at the same time, the outer limiting part makes the movement of the top positioning block 203 more stable and smooth.

[0035] The end positioning block 306 and the top positioning block 203 can be fixed to the slider 301 and the pressure block 201 in any suitable manner, such as by screwing. The replaceability of the end positioning block 306 and the top positioning block 203 ensures that they are always compatible with the paint removal end of the copper wire 4 to meet the paint removal end requirements of different lengths or to adapt to copper wires 4 of different specifications, thus ensuring accurate positioning of the copper wire 4.

[0036] Furthermore, the bottom of the outer side of the top positioning block 203 has a limiting notch 2031. The inner contour of the limiting notch 2031 matches the outer contour of the copper wire 4, and the width of the limiting notch 2031 is smaller than that of the copper wire 4. After the top positioning block 203 is pressed down, the limiting notch 2031 will limit the left and right direction of the copper wire 4, ensuring that the side of the copper wire 4 at the paint removal end protrudes outward from the outer side of the top positioning block 203 and the end positioning block 306, so as to facilitate the paint removal operation.

[0037] The copper wire 4 has a smooth surface, and the positioning step surface 303 slides against the surface of the copper wire 4, allowing the positioning step surface 303 to slide relative to the copper wire 4. To reduce friction, the sliding distance of the slider 301 is usually short, and the extension direction of the copper wire 4 is opposite to the scraping direction of the paint, to ensure the stability of the copper wire 4 during the paint scraping process.

[0038] In addition, the device also includes a mounting connection block 5, the fixed connection block 1 is fixedly mounted on the top of the mounting connection block 5, and the mounting connection block 5 has connection holes on both sides for connection, for mounting on the surface of other devices.

[0039] The working principle of this utility model is as follows:

[0040] First, place the copper wire 4 on the positioning step surface 303. At this time, it is not necessary to align the end position of the copper wire 4 to avoid hard contact between the end of the copper wire 4 and the end wall of the positioning step surface 303. Then, activate the top positioning cylinder 202 to drive the pressure block 201 to press down, so that the top positioning block 203 presses the top of the copper wire 4 to form a top limit. Next, activate the end positioning cylinder 302 to drive the connecting rod 304 to press down, drive the slider 301 to move horizontally, and the positioning step surface 303 moves horizontally at the same time and abuts against the end of the copper wire 4 to form an end limit.

[0041] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0042] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
