Description

Technical Field

[0001] This application relates to the field of coil processing technology, and in particular to a coil lead cutting machine fixture. Background Technology

[0002] During the coil manufacturing process, tin beads are generated after the ends of the coil leads are tinned. The leads need to be aligned to ensure the structural regularity of the coil, and excess tin beads need to be removed to avoid tin bead residue affecting the subsequent assembly and performance of the coil.

[0003] In related technologies, the alignment of coil leads and the removal of solder beads are mainly done manually. Operators use clamps to tidy up the coil leads and use brushes to remove excess solder beads to meet the production quality requirements of the coil.

[0004] However, manual processing relies on the operator's skill and operational stability, which can lead to low efficiency in tidying up coil leads and removing solder balls. This makes it difficult to adapt to the pace of large-scale production, and manual operation can result in low consistency in coil quality due to differences in operating habits and other factors. Utility Model Content

[0005] To address the aforementioned problems, this application provides a coil lead cutting machine fixture.

[0006] The coil lead cutting machine fixture provided in this application adopts the following technical solution: A coil cutting machine fixture includes a base, a first shaping blade, a second shaping blade, a first cutting blade, and a second cutting blade. The first shaping blade is fixed to the base and disposed in the middle of the base. The second shaping blade, the first cutting blade, and the second cutting blade are slidably disposed on the base in a horizontal direction. The first shaping blade and the second shaping blade are disposed opposite to each other, as are the first cutting blade and the second cutting blade. The first cutting blade is disposed below the first shaping blade, and the second cutting blade is disposed below the first shaping blade. The first shaping blade is provided with an insertion groove, and the second shaping blade is provided with an insertion block. The insertion block is inserted into the insertion groove. Both the first cutting blade and the second cutting blade are provided with cutting edges. When the first cutting blade and the second cutting blade slide relative to each other, the cutting edges abut against each other.

[0007] By adopting the above technical solution, the insertion slot can pre-position the coil pins. When the second shaping blade slides horizontally, the insertion block and the insertion slot engage. The relative movement between the insertion block and the insertion slot automatically straightens the coil end. The sliding process is stable and controllable, ensuring that the pin straightening effect of each batch of coils is consistent. This solves the problem of low processing quality consistency caused by differences in habits during manual operation. At the same time, when the first and second cutting blades slide relative to each other horizontally, their cutting edges abut each other, which can cut off the solder ball part of the coil pin, replacing the manual method of cleaning solder balls with a brush. The mechanical cutting action is fast and continuous, which greatly improves the solder ball removal efficiency and can adapt to the pace of large-scale production. Through the automatic straightening of the shaping blade and the cutting of the cutting blade, the end processing of the coil pins is automated, which not only improves the processing efficiency but also ensures the stability of the processing quality.

[0008] Preferably, both the insertion slot and the insertion block are V-shaped, and both the top of the insertion block and the top of the insertion slot are provided with arc grooves. The insertion block is inserted into the insertion slot, and the edge of the arc groove abuts against it.

[0009] By adopting the above technical solution, the V-shaped insertion slot and insertion block, through the guiding effect of the inclined surface, can automatically center and position the coil end during the insertion process, ensuring that the coil does not shift during straightening. When the edge of the arc groove at the top of the insertion slot and the insertion block abuts, it can fit with the contour of the coil pin. The soft contact of the arc surface of the arc groove enhances the wrapping of the coil pin, ensuring that the coil pin end is evenly straightened when the insertion block and the insertion slot slide relative to each other. This avoids the problem of incomplete straightening caused by uneven force or difference in operating angle when manually straightening with clamps, further ensuring the accuracy of subsequent solder bead cutting and improving the overall automation level of the process.

[0010] Preferably, it further includes a first driving cylinder and a second driving cylinder, the first driving cylinder and the second driving cylinder are fixedly connected to the base, the piston rod of the first driving cylinder is fixedly connected to the first cutter, the second driving cylinder is fixedly connected to the second shaping blade and the second cutter, and the first driving cylinder and the second driving cylinder are connected to an external air supply device.

[0011] By adopting the above technical solution, the external air supply equipment can provide a continuous and stable air source for the first and second drive cylinders, ensuring that the driving force output of the first and second drive cylinders is uniform and consistent. When the piston rod of the second drive cylinder drives the second shaping blade to slide, the stable driving force of the second drive cylinder can ensure that the plug block and the plug slot are accurately plugged in, ensuring that the coil pins are evenly straightened. At the same time, the first and second drive cylinders drive the first and second cutters to slide relative to each other, ensuring that the blades accurately contact and stabilize the solder ball part of the coil pins to be cut off. This avoids the problem of incomplete straightening caused by uneven force or difference in operating angle when manually straightening with clamps. In addition, the mechanical action driven by the first and second drive cylinders is fast and can be continuously cycled, which greatly improves the overall efficiency of wire sorting and solder ball cutting, and can adapt to the pace of large-scale production.

[0012] Preferably, it also includes a waste recycling box, a support seat is provided on the upper surface of the base, the support seat is fixed on the base, the first shaping blade is fixed on the upper surface of the support seat, the support seat is provided with a sliding groove, and the waste recycling box is slidably disposed in the sliding groove.

[0013] By adopting the above technical solution, the support base is fixed to the base and carries the first shaping blade, providing a stable installation foundation for the first shaping blade. At the same time, the sliding groove provides a stable sliding path for the waste recycling box, so that the sliding groove can accurately connect with the cutting areas of the first and second cutting blades, efficiently collecting solder ball waste. Moreover, the sliding setting facilitates quick removal and cleaning of the waste recycling box, ensuring the cleanliness of the production environment.

[0014] Preferably, the side wall of the support base is provided with a clearance groove, and the first cutter and the second cutter are slidably disposed in the clearance groove, and the clearance groove is in communication with the sliding groove.

[0015] By adopting the above technical solution, the clearance groove restricts the movement direction of the cutter through the limiting effect, ensuring the stability of the relative sliding trajectory of the first cutter and the second cutter, thereby ensuring that the cutting edges of the first cutter and the second cutter can accurately abut against each other, achieving precise cutting of the solder ball part of the coil lead. The clearance groove is connected to the sliding groove, so that the solder ball waste generated by the first cutter and the second cutter can fall directly into the waste recycling box in the sliding groove.

[0016] Preferably, it also includes a cover plate, which is fixed to the upper surface of the first shaping blade, and the cover plate is provided with a limiting groove.

[0017] By adopting the above technical solution, operators can directly place the coil in the limiting groove. The limiting groove can standardize the placement of the coil, ensure that the coil pins are accurately aligned with the insertion slot, reduce the coil position deviation caused by the randomness of operation during manual placement, and keep the initial placement state of each coil consistent.

[0018] Preferably, the waste recycling box is provided with a limiting plate, the waste recycling box is built into the support base, and the limiting plate abuts against the outer wall of the support base.

[0019] By adopting the above technical solution, the limiting plate can restrict the sliding position of the waste recycling box in the sliding groove, ensuring that the waste recycling box is always directly below the first cutter and the second cutter, thereby ensuring that the solder ball waste generated by the first cutter and the second cutter can fall accurately into the box, so that the waste recycling box can reduce the impact of positional deviation on waste collection during continuous production.

[0020] Preferably, the waste recycling box is provided with a handle, which is fixed to the side wall of the waste recycling box.

[0021] By adopting the above technical solution, the handle provides a clear point of force for the operator to pick up and put down the waste recycling box. The operator can easily slide the waste recycling box out of the sliding groove by holding the handle, so as to quickly clean up the solder ball waste collected inside. After cleaning, the recycling box can be accurately slid back into the sliding groove by the handle. The stable positioning of the waste recycling box is achieved by the contact between the limiting plate and the outer wall of the support base.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The insertion slot is pre-positioned for the coil pins. When the second shaping blade slides, the insertion block and the insertion slot are engaged. The relative movement of the insertion block and the insertion slot automatically straightens the coil pins, ensuring consistent processing results for each batch. This solves the problem of low quality consistency caused by differences in habits during manual operation. At the same time, when the first and second cutting blades slide relative to each other, the cutting edges of the first and second cutting blades abut against each other and can cut off the solder beads on the coil pins, replacing the manual cleaning method. This improves the output efficiency to adapt to large-scale production and ensures the stability of processing quality. 2. Both the insertion slot and the insertion block are V-shaped, and an arc groove is set at the top of the insertion slot and the insertion block. The V-shaped inclined surface guides the coil pins to be automatically centered during insertion, reducing offset during straightening. When the two arc grooves come into contact, they fit the outline of the coil pins, ensuring that the coil pins are evenly straightened when the insertion block and the insertion slot slide relative to each other. This avoids the problem of local misalignment caused by uneven force or angle difference during manual straightening, further ensuring the accuracy of subsequent solder ball cutting and improving the automation level of the overall process. 3. The cover plate is fixed to the upper surface of the first shaping knife and is provided with a limiting groove. The operator can place the coil in the limiting groove to standardize the placement of the coil, ensure that the coil pins are accurately aligned with the insertion slot, reduce the positional deviation of manual placement, and keep the initial placement state of each coil consistent.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses a jig for a coil lead cutting machine. (Refer to...) Figure 1A coil lead cutting machine fixture includes a base 1, a support 10, a first shaping blade 2, a second shaping blade 3, a first cutting blade 4, a second cutting blade 5, a first driving cylinder 6, a second driving cylinder 7, a waste recycling box 8, and a cover plate 9. The support 10 is fixed to the upper surface of the middle part of the base 1, the first shaping blade 2 is fixed on the support 10, and the second shaping blade 3, the first cutting blade 4, and the second cutting blade 5 are slidably disposed on the base 1 in the horizontal direction. The first shaping blade 2 and the second shaping blade 3 are disposed opposite each other to tidy up the coil leads, and the first cutting blade 4 and the second cutting blade 5 are disposed opposite each other to cut off the solder bead portion of the coil leads.

[0033] Furthermore, the first drive cylinder 6 drives the first cutter 4 to slide along the length of the base plate, the second drive cylinder 7 drives the second shaping cutter 3 and the second cutter 5 to slide along the length of the base plate, the waste recycling box 8 is slidably disposed in the support seat 10 for recycling waste, and the cover plate 9 is fixed to the upper surface of the first shaping cutter 2 for limiting the coil.

[0034] Reference Figure 2 Specifically, the base 1 is the basic support component of the entire fixture. The support seat 10 is fixed to the upper surface of the base 1 and located in the middle of the base 1. The support seat 10 provides a mounting position for the first shaping blade 2. The first shaping blade 2 is fixed to the upper surface of the support seat 10, as shown in the figure. Figure 3 The first shaping blade 2 is provided with a insertion groove 21, which is V-shaped. In this embodiment, there are six insertion grooves 21, and the top of the insertion groove 21 is provided with an arc groove 11.

[0035] Furthermore, the second shaping blade 3 is slidably mounted on the base 1 in a horizontal direction. The second shaping blade 3 is equipped with insertion blocks 31, which are also V-shaped. There are six insertion blocks 31 in total. (Refer to...) Figure 4 Furthermore, the top of the plug-in block 31 is also provided with an arc groove 11. The plug-in block 31 is plugged into the plug groove 21. When the second shaping blade 3 slides towards the first shaping blade 2, the plug-in block 31 is inserted into the plug groove 21, and the edges of the two arc grooves 11 abut against each other. This kind of cooperation can effectively organize the coil pins and keep the coil pins in a neat state.

[0036] This demonstrates that, since both the insertion slot 21 and the insertion block 31 are designed with a V-shaped structure, the inclined surface of the V-shaped structure guides the automatic centering and positioning of the coil pins during the insertion and engagement process, ensuring that the coil does not shift during the straightening process. When the second shaping blade 3 slides horizontally, the relative movement of the insertion slot 21 and the insertion block 31 can stably and automatically straighten the ends of the coil pins. The arc groove 11 at the top of the insertion slot 21 abuts against the edge of the arc groove 11 at the top of the insertion block 31, making the arc surface and the outline of the coil pins form a soft fit, thereby enhancing the wrapping of the pins and achieving synchronous straightening of the coil pins. This avoids the problem of inadequate local processing caused by differences in force or angle deviation during manual operation, ensuring the straightening consistency of each batch of coil pins and improving the positioning accuracy of subsequent solder bead cutting through precise geometric matching, ultimately achieving an automated upgrade of the coil processing process.

[0037] In addition, the cover plate 9 is fixed to the upper surface of the first shaping knife 2. The cover plate 9 is provided with a limiting groove 91. The limiting groove 91 can further limit the coil. The operator can directly place the coil in the limiting groove 91. The limiting groove 91 can standardize the placement position of the coil and ensure that the coil pins are accurately aligned with the insertion slot 21. This reduces the problem of coil position deviation caused by arbitrary operation during manual placement and keeps the initial placement state of each coil consistent.

[0038] Reference Figure 5 Furthermore, the sliding action of the second shaping blade 3 can be realized by the second driving cylinder 7. The second driving cylinder 7 is fixedly connected to the base 1, and a second connecting seat 14 is provided between the second driving cylinder 7 and the second shaping blade 3. The piston rod of the second driving cylinder 7 is fixedly connected to the second connecting seat 14, and the second shaping blade 3 is fixedly connected to the second connecting seat 14. When the external air supply device supplies air to the second driving cylinder 7, the piston rod of the second driving cylinder 7 pushes the second shaping blade 3 to slide.

[0039] Reference Figure 6 On the other hand, the first cutter 4 is located below the first shaping cutter 2, and the second cutter 5 is located below the second shaping cutter 3. The first cutter 4 and the second cutter 5 are arranged opposite each other. Both the first cutter 4 and the second cutter 5 are provided with a cutting edge 12. When the first cutter 4 and the second cutter 5 slide relative to each other for a certain distance, the cutting edge 12 abuts. The side wall of the support base 10 is provided with a relief groove 101. The first cutter 4 and the second cutter 5 slide and are arranged in the relief groove 101. The relief groove 101 provides space for the movement of the cutter.

[0040] This demonstrates that during the sliding process, the cutting edges 12 of the first cutter 4 and the second cutter 5 abut against each other, which can quickly cut off the solder ball portion of the coil pin, replacing the traditional manual method of brushing off solder balls. This significantly improves processing efficiency and adapts to the needs of large-scale production. The clearance groove 101 ensures the stability of the relative sliding trajectory of the first cutter 4 and the second cutter 5 by constraining the movement direction of the first cutter 4 and the second cutter 5. Thus, the entire process of cutting the solder ball portion of the coil pin is automated on the basis of automatic straightening. This solves the problem of solder ball residue or over-cutting caused by angle deviation or uneven force in manual operation, and ensures the stability of cutting quality.

[0041] Furthermore, the sliding of the first cutter 4 is driven by the first drive cylinder 6, which is fixedly connected to the base 1. A first connecting seat 13 is provided between the first cutter 4 and the first drive cylinder 6. The piston rod of the first drive cylinder 6 is fixedly connected to the first connecting seat 13. The first cutter 4 is fixedly connected to the first connecting seat 13. When the external air supply device supplies air to the first drive cylinder 6, the piston rod of the first drive cylinder 6 pushes the first cutter 4 to slide. The second cutter 5 is fixedly connected to the second connecting seat 14. When the external air supply device supplies air to the second drive cylinder 7, the piston rod of the second drive cylinder 7 pushes the second cutter 5 to slide.

[0042] Reference Figure 7 Furthermore, a sliding groove 102 is provided inside the support base 10, and the waste recycling box 8 is slidably disposed within the sliding groove 102. A handle 81 is fixedly provided on the side wall of the waste recycling box for operators to pull out and clean the waste. At the same time, the waste recycling box 8 is provided with a limiting plate 82. When the waste recycling box 8 is placed inside the sliding groove 102, the limiting plate 82 abuts against the outer wall of the support base 10, constraining the position of the sliding waste recycling box 8 to ensure that the waste recycling box 8 is always directly below the first cutter 4 and the second cutter 5, thereby achieving accurate collection of solder ball waste. The handle 81 provides the operator with a clear point of force application, allowing the waste recycling box 8 to slide smoothly out along the sliding groove 102 to complete the emptying operation of the waste recycling box 8. The waste recycling box 8 can also be accurately reset into the sliding groove 102 by holding the handle 81. Finally, the positioning of the waste recycling box 8 is achieved by the abutment action of the limiting plate 82 and the support base 10. In addition, the sliding groove 102 is connected to the clearance groove 101, so that the solder ball waste generated by the first cutter 4 and the second cutter 5 can fall directly into the waste recycling box 8 in the sliding groove 102.

[0043] The implementation principle of a coil lead cutting machine fixture in this application embodiment is as follows: The operator pushes the waste recycling box 8 along the sliding groove 102 of the support base 10 until the limiting plate 82 abuts against the outer wall of the support base 10, ensuring that the waste recycling box 8 is directly below the first cutter 4 and the second cutter 5. Then, the operator places the coil in the limiting groove 91 of the cover plate 9, so that the coil leads are accurately placed into the insertion groove 21 of the first shaping blade 2. An external air supply device supplies air to the second drive cylinder 7. The piston rod of the second drive cylinder 7 pushes the second shaping blade 3 to slide towards the first shaping blade 2 through the second connecting seat 14. The insertion block 31 moves with the second shaping blade 3 and inserts into the insertion groove 21, so that the coil leads are evenly straightened, completing the shaping.

[0044] While the coil leads are being straightened evenly, an external air supply device drives the first drive cylinder 6. Since the second drive cylinder 7 is also fixedly connected to the second cutter 5, the first drive cylinder 6 drives the first cutter 4 to slide through the first connecting seat 13, and the second drive cylinder 7 drives the second cutter 5 to slide synchronously through the second connecting seat 14. The two first cutters 4 and the second cutter 5 move relative to each other along the relief groove 101 of the support seat 10, and the cutting edge 12 gradually comes into contact, cutting off the solder ball part of the coil leads. The solder ball waste generated by cutting falls into the waste recycling box 8.

[0045] After the cutting is completed, the first drive cylinder 6 and the second drive cylinder 7 drive the second shaping blade 3, the first cutting blade 4 and the second cutting blade 5 to reset, waiting for the next operation. When the waste material in the waste recycling box 8 accumulates to a certain amount, the operator holds the handle 81 and pulls the waste recycling box 8 out along the sliding groove 102. After cleaning, the waste recycling box 8 is pushed back to its original position through the handle 81. The limiting plate 82 abuts against the outer wall of the support seat 10 to achieve the positioning of the waste recycling box 8.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
