TECHNICAL FIELD

[0001] The present application relates to the technical field of inductor production, in particular to a coil forming and processing device for manufacturing inductors. BACKGROUND

[0002] The manufacturing process of integrally formed inductors is generally to place the wound coil in a mold, then inject or press the magnetic powder mixed with the adhesive into the mold, and completely cover the coil; under high temperature and high pressure, the magnetic powder and the adhesive are solidified to form a solid and dense whole structure, that is, the magnetic core and the coil are integrated. This process makes the inductor have better structural stability, higher saturation current and lower loss.

[0003] During the manufacturing process of the inductor element, the enameled wire needs to be processed into a coil, and then the two terminals of the coil are welded with the material belt. During the process of processing the wire bundle into a coil, the end of the wire bundle is usually fixed on the winding column, and then the winding column is driven to rotate around its own axis by the rotating mechanism, while the winding column is driven to slide along its own axis direction by the moving mechanism, so as to wind the wire bundle on the outer wall of the winding column to form a spiral structure; after winding is completed, the end of the wire bundle is cut off, that is, the required coil is formed; then the coil on the winding column is moved to the next station for welding by the transfer mechanism. The manufacturing process of the inductor element has many procedures, so a forming and processing device capable of balancing work efficiency and processing precision is needed. SUMMARY

DETAILED DESCRIPTION

[0050] The following Figures 1-15 The application is further described in detail.

[0051] Embodiment 1: The embodiment of the application discloses a coil forming processing device for manufacturing inductors. Figure 1 The coil forming processing device for manufacturing inductors comprises a machine 1 and a shaping mechanism 7, a stripping mechanism 8, a conveying mechanism 2, a winding mechanism 3, a transfer mechanism 4 and a welding mechanism 5 arranged on the machine 1 in sequence, and the mechanisms are matched with each other and can jointly complete the manufacturing process from enameled wire to inductor coil and then to welding with a piece, thereby helping to improve work efficiency and processing precision.

[0052] Referring to Figure 1 and Figure 2In the embodiment, the top surface of the machine table 1 is horizontally arranged. The shaping mechanism 7 is provided with four groups, two groups are arranged on one side of the machine table 1, and the other two groups are arranged on the other side of the machine table 1, so that four winding enameled wires can be shaped at the same time, which helps to improve the work efficiency. The shaping mechanism 7 comprises a mounting plate 71 and a plurality of rollers 72 rotatably connected to the same side of the mounting plate 71, and the axes of the plurality of rollers 72 are parallel. The mounting plate 71 is provided with two; one of the mounting plates 71 is vertically arranged, and the axes of the rollers 72 on the mounting plate 71 are horizontally arranged; the other mounting plate 71 is horizontally arranged, and the axes of the rollers 72 on the mounting plate 71 are vertically arranged. The rollers 72 are provided with wire grooves, and the enameled wires move in the wire grooves, which can avoid the enameled wires from deviating relative to the rollers 72 during movement. The enameled wires pass between the rollers 72, and the rollers 72 can exert pressure on the enameled wires in different directions, so that the enameled wires are gradually stretched and straightened during movement, thereby shaping the winding enameled wires into straight lines.

[0053] With reference to Figure 1 and Figure 3 , the stripping mechanism 8 is provided with four groups, two groups are arranged on one side of the machine table 1, and the other two groups are arranged on the other side of the machine table 1, and each group of the stripping mechanism 8 corresponds to a shaping mechanism 7. The stripping mechanism 8 comprises a motor, a belt transmission assembly and a stripping knife. The output shaft of the motor is arranged along the length direction of the machine table 1, the belt transmission assembly comprises a belt and two pulleys matched with the belt, one of the pulleys is coaxially fixedly connected with the output shaft of the motor, and the other pulley is coaxially fixedly connected with the stripping knife. Thus, the motor can drive the stripping knife to rotate through the belt transmission assembly, and the enameled wire passes through the stripping knife, so that the rotating stripping knife can scrape off the wire skin on the outside of the enameled wire, thereby completing the stripping process.

[0054] With reference to Figure 3 , the machine table 1 is further provided with a guide rod 9 and a lead screw 10 along the length direction of the machine table 1, the guide rod 9 is fixedly connected to the top wall of the machine table 1, and the lead screw 10 is rotatably connected to the top wall of the machine table 1 around the axis thereof. The machine table 1 is further provided with a sliding plate 11, and the stripping mechanism 8 is arranged on the top wall of the sliding plate 11; the sliding plate 11 is slidably arranged on the guide rod 9, and the sliding plate 11 is threadedly connected with the lead screw 10. Thus, rotating the lead screw 10 can drive the sliding plate 11 to slide, thereby facilitating adjustment of the initial position of the stripping mechanism 8. The end of the lead screw 10 is fixedly connected with a hand wheel, thereby facilitating rotation of the lead screw 10; the friction angle of the thread on the lead screw 10 is greater than the guide angle, thereby the lead screw 10 has self-locking ability, and when the lead screw 10 stops rotating, the sliding plate 11 can be locked at the current position, thereby ensuring normal work of the stripping mechanism 8. After the stripping treatment by the stripping mechanism 8, the straight enameled wires form a straight wire harness, and then continue to be conveyed. The sliding plate 11 is provided with two, which are respectively located on the two sides of the machine table 1, and each sliding plate 11 corresponds to two groups of stripping mechanisms 8.

[0055] Referring to Figure 1 and Figure 4 , the conveying mechanism 2 is provided with two groups and is located at two sides of the machine table respectively, and each conveying mechanism 2 can convey two wire harnesses simultaneously. The conveying mechanism 2 comprises a third linear driving member 21, a sliding seat 22 and a fourth linear driving member 23. The third linear driving member 21 is a linear motor; in other embodiments, the third linear driving member 21 can also be a pneumatic cylinder. The third linear driving member 21 is fixedly installed on the top wall of the machine table 1 along the length direction of the machine table 1. The sliding seat 22 is fixedly installed on the movable end of the third linear driving member 21, so that the third linear driving member 21 can drive the sliding seat 22 to slide horizontally. The fourth linear driving member 23 is a pneumatic cylinder; in other embodiments, the fourth linear driving member 23 can also be an electric push rod; the cylinder body of the fourth linear driving member 23 is fixedly installed on the sliding seat 22, and the piston rod of the fourth linear driving member 23 is vertically downward. The end of the piston rod of the fourth linear driving member 23 is fixedly installed with a pressing block, and the bottom wall of the pressing block can abut against the sliding seat 22. The wire harness passes between the sliding seat 22 and the pressing block, and when the pressing block is located above the wire harness and the pressing block does not contact the wire harness, the wire harness can move normally and be conveyed; when the fourth linear driving member 23 drives the pressing block to move downward and makes the pressing block abut tightly against the wire harness on the sliding seat 22, the sliding of the wire harness relative to the sliding seat 22 is limited, so that the wire harness can be moved simultaneously when the third linear driving member 21 drives the sliding seat 22 to slide horizontally, thereby realizing the conveying of the wire harness.

[0056] Since the length of the third linear driving member 21 is limited, when the sliding seat 22 moves to the end of the third linear driving member 21, the fourth linear driving member 23 drives the pressing block to move upward to release the wire harness, and then the third linear driving member 21 drives the sliding seat 22 to slide reversely and reset to the initial state; then the fourth linear driving member 23 drives the pressing block to move downward again to press and fix the wire harness on the sliding seat 22, so that the wire harness can be conveyed forward continuously.

[0057] Referring to Figure 1 and Figure 4 , each sliding seat 22 in the conveying mechanism 2 at each side of the machine table 1 is provided with two, and each sliding seat 22 is used for conveying one wire harness. Referring to Figure 4 , the two sliding seats 22 located at the same side of the machine table 1 are fixedly connected through a connecting plate 12, and one of the sliding seats 22 is fixedly connected with the movable end of the third linear driving member 21, so that the two sliding seats 22 can slide synchronously under the action of the third linear driving member 21, which is helpful to simplify the structure. In addition, the two ends of each sliding seat 22 are fixedly connected with guide cylinders 221, and the guide cylinders 221 at the two ends of each sliding seat 22 are coaxially arranged; the wire harness passes through the guide cylinders 221, so that the wire harness is not easy to deviate during the conveying process.

[0058] Referring toFigure 5 and Figure 6 The winding mechanism 3 is provided with two groups, which are located on the two sides of the machine table 1 respectively, and each group of winding mechanism 3 can realize winding of two wire harnesses. The winding mechanism 3 comprises a winding column 31, a connecting seat 32 and a rotating lifting assembly 33. The inside of the machine table 1 is hollow, which is convenient for placing parts; the rotating lifting assembly 33 is provided with two groups and is arranged in an upper and lower interval, one group of rotating lifting assembly 33 is located above the top wall of the machine table 1, and the other group of rotating lifting assembly 33 is located in the inside of the machine table 1 (refer to Figure 9 ). The movable end of the rotating lifting assembly 33 located above the top wall of the machine table 1 is connected with the winding column 31, and the winding column 31 is vertically arranged; the movable end of the rotating lifting assembly 33 located in the inside of the machine table 1 is connected with the connecting seat 32, and the connecting seat 32 is located below the winding column 31; the outer side of the connecting seat 32 is provided with a clamping assembly 35 for clamping the end of the wire harness.

[0059] Therefore, when the clamping assembly 35 clamps and fixes the end of the wire harness on the connecting seat 32, the winding column 31 and the connecting seat 32 move downward together, at the same time, the connecting seat 32 rotates around the vertical axis, so that the wire harness can be wound on the winding column 31 from bottom to top; then the winding column 31 and the connecting seat 32 move upward together, at the same time, the connecting seat 32 continues to rotate around the vertical axis, so that the wire harness can be wound on the winding column 31 from top to bottom; that is, during winding, the movable ends of the two groups of rotating lifting assemblies 33 arranged in an upper and lower interval move synchronously, and each vertical sliding of the movable end of the rotating lifting assembly 33 can complete winding of a layer of coil, and the number of winding layers of the coil in the radial direction thereof can be selected according to needs. In the present scheme, the coil is wound with two layers of inside and outside.

[0060] Refer to Figure 6 The winding mechanism 3 further comprises a cutting assembly 36, which is provided with two groups corresponding to the two wire harnesses on the same side of the machine table 1. The cutting assembly 36 comprises a first cylinder 361 and a cutter 362, the cylinder body of the first cylinder 361 is fixedly connected to the top wall of the machine table 1, and the piston rod of the first cylinder 361 is arranged along the width direction of the machine table 1; the end of the piston rod of the first cylinder 361 is fixedly connected with the cutter 362.

[0061] The end of the wire harness is in a separated state from the pressing block of the fourth linear driving member 23 during the winding process, so that the wire harness can be conveyed along the length direction of the wire harness, thereby smoothly completing the winding process. After the winding process of the end of the wire harness on the winding column 31 is completed, the piston rod of the fourth linear driving member 23 is extended, so that the pressing block is lowered and the wire harness is tightly fixed on the sliding seat 22; at this time, the end of the wire harness away from the winding column 31 is tightly fixed on the sliding seat 22, and the end of the wire harness close to the winding column 31 is fixed on the connecting seat 32 by the clamping assembly 35, so that the first cylinder 361 drives the cutter 362 to slide outwards, thereby cutting the end of the wire harness, so that the wire harness is separated from the coil after winding, and the subsequent transfer of the formed coil is facilitated.

[0062] It should be noted that since the wire harness is formed after the enameled wire is stripped, the wire harness has certain viscosity. After the wire harness is wound on the outer wall of the winding column 31 and cut, the wire harness will adhere to the outer wall of the winding column 31.

[0063] In the embodiment, the cutting process of the end of the wire harness is completed by a single cutter 362, and in other embodiments, two cutters 362 can be provided for cutting the wire harness. For example, a pneumatic clamp jaw is fixedly installed at the end of the piston rod of the first cylinder 361, both movable ends of the pneumatic clamp jaw slide in the vertical direction, and the sliding directions of the two movable ends of the pneumatic clamp jaw are opposite; one cutter is fixedly installed at each movable end of the pneumatic clamp jaw, and the side close to each other of the two cutters is a blade; thus, after the winding of the wire harness is completed, the first cylinder 361 drives the pneumatic clamp jaw and the cutters to translate, and the two cutters are located on the upper and lower sides of the wire harness, respectively, and then the pneumatic clamp jaw drives the two cutters to approach each other to cut the wire harness; then the piston rod of the first cylinder 361 is retracted, so that the starting clamp jaw and the cutters are away from the wire harness, thereby avoiding interference with the subsequent process. Alternatively, a cutter is arranged at one movable end of the pneumatic clamp jaw, and a pressing plate is arranged at the other movable end of the pneumatic clamp jaw, and the pneumatic clamp jaw drives the cutter and the pressing plate to approach each other, thereby cutting the wire harness.

[0064] Referring to Figure 7 and Figure 8In order to guarantee the winding effect of the coil, the top wall of the connecting seat 32 is fixedly connected with a connecting block 321, a vertical guide groove 3211 is formed in the top of the connecting block 321, the guide groove 3211 is a circular groove, the axis of the guide groove 3211 is coaxially arranged with the rotating axis of the connecting seat 32, and the cross-sectional diameter of the guide groove 3211 is the same as the diameter of the winding column 31. When winding, the bottom end of the winding column 31 is first inserted into the guide groove 3211, at this time, a part of the winding column 31 is located outside the guide groove 3211, so that the wire harness can be wound on the outer wall of the part of the winding column 31 located outside the guide groove 3211. The guide groove 3211 can guide the winding column 31, so that after the end of the winding column 31 is inserted into the guide groove 3211, the winding column 31 and the connecting block 321 can rotate around the same axis, thereby guaranteeing the uniformity of winding.

[0065] Referring to Figure 8 , the connecting block 321 is provided with a receiving groove 3212, a stop block 3213 is fixedly connected to the inner wall of the receiving groove 3212, the stop block 3213 is vertically arranged, and the top end of the stop block 3213 is located above the top wall of the connecting block 321. The clamping assembly 35 is arranged outside the connecting block 321, and the clamping assembly 35 can tightly fix the end of the wire harness on the stop block 3213, so that the end of the wire harness can rotate together with the connecting seat 32 and the connecting block 321 during the winding process.

[0066] Referring to Figure 7 and Figure 8 , the clamping assembly 35 includes an abutting piece 351, an elastic piece, a pushing ring 352, and a second linear drive 353. The abutting piece 351 includes a vertical fixedly connected abutting rod 3511 and a connecting rod 3512, and the abutting rod 3511 and the connecting rod 3512 together form an L-shaped structure. The end of the connecting rod 3512 close to the abutting rod 3511 is hinged to the connecting seat 32, and the hinge axis is horizontal; the elastic piece is a torsion spring, and the elastic piece is fixedly connected between the connecting rod 3512 and the connecting seat 32, and in the normal state, the torsion spring is in a twisted state, so that the top end of the abutting rod 3511 tightly abuts in the receiving groove 3212, at this time, the abutting rod 3511 is in a vertical state, and the connecting rod 3512 is in a horizontal state. The second linear drive 353 is a pneumatic cylinder, the cylinder body of the second linear drive 353 is fixedly connected to the rotary lifting assembly 33 corresponding to the connecting seat 32 (referring to Figure 11 ); in other embodiments, the second linear drive 353 can also be an electric push rod. The piston rod of the second linear drive 353 is vertically upward, and the end of the piston rod of the second linear drive 353 is fixedly connected with the pushing ring 352, the pushing ring 352 is sleeved outside the connecting seat 32, the pushing ring 352 is located below the connecting rod 3512, and the pushing ring 352 is used to abut against the bottom end of the connecting rod 3512.

[0067] In normal state, the top end of the abutting rod 3511 abuts against the block 3213; when the second linear driving element 353 drives the abutting ring 352 to move upward, the abutting ring 352 can push the end of the connecting rod 3512 to move upward, so that the connecting rod 3512 drives the abutting rod 3511 to rotate, and the top end of the abutting rod 3511 can be separated from the block 3213; since the wire harness is horizontally conveyed into the area between the top end of the abutting rod 3511 and the top end of the block 3213, when the piston rod of the second linear driving element 353 is retracted, the elastic element can drive the abutting rod 3511 to rotate reversely, and at this time, the abutting rod 3511 can abut the end of the wire harness against the top end of the block 3213, so as to complete the fixation of the end of the wire harness.

[0068] The top end of the abutting rod 3511 is provided with a notch, so that the end of the wire harness can be abutted between the notch on the abutting rod 3511 and the block 3213, thereby ensuring the abutting fixation effect of the end of the wire harness.

[0069] Referring to Figure 9 , Figure 10 and Figure 11 , the rotary lifting assembly 33 is provided with two groups, the rotary lifting assembly 33 located above the top wall of the machine table 1 is used to drive the winding column 31 to rotate and lift, and the rotary lifting assembly 33 located inside the machine table 1 is used to drive the connecting seat 32 to rotate and lift. Referring to Figure 10 , the rotary lifting assembly 33 corresponding to the winding column 31 will be taken as an example for description, which is located above the machine table 1 and includes a linear module 331, a driving motor 332, a pulley set 333 and a rotating drum 334. The fixed end of the linear module 331 is fixedly arranged on the machine table 1, the linear module 331 is vertically arranged, the movable end of the linear module 331 is fixedly connected with the support plate 13, and the linear module 331 can drive the support plate 13 to slide in the vertical direction; the linear module 331 is used to drive the lifting process of the winding column 31, and the linear module 331 has high movement precision, so that the winding column 31 can slide in the vertical direction accurately in the winding process, thereby ensuring the winding effect.

[0070] Referring to Figure 10 , the driving motor 332 is fixedly installed on the support plate 13, and the output shaft of the driving motor 332 vertically downward; the axis of the rotating drum 334 is vertically arranged, and the rotating drum 334 is rotationally connected to the support plate 13 about the axis thereof; the pulley set 333 is connected between the output shaft of the driving motor 332 and the rotating drum 334, so that the driving motor 332 can drive the rotating drum 334 to rotate through the pulley set 333. The bottom end of the rotating drum 334 is connected with the winding column 31, so that the rotating drum 334 can drive the winding column 31 to rotate when the rotating drum 334 rotates, thereby driving the rotating process of the winding column 31.

[0071] Referring to Figure 10 andFigure 11 The two rotating and lifting assemblies 33 are identical in structure but different in installation position, so the structure of the rotating and lifting assembly 33 corresponding to the connecting seat 32 will not be repeated here.

[0072] Thus, when winding, the end of the wire harness is first clamped and fixed on the connecting block 321, then the winding column 31 is lowered and the bottom end of the winding column 31 is inserted into the guide groove 3211 at the top of the connecting block 321, then the winding column 31 and the connecting seat 32 are synchronously rotated, and at the same time, the winding column 31 and the connecting seat 32 are synchronously lowered; since one end of the wire harness is drawn out of the guide cylinder 221, and the installation height of the guide cylinder 221 remains constant, as the winding column 31 and the connecting seat 32 rotate and lower, the wire harness can be prevented from rotating in place, so that the end of the wire harness is gradually wound on the outer wall of the winding column 31; after winding the required number of turns along the axis direction of the winding column 31, the winding column 31 and the connecting seat 32 change the moving direction, at this time the winding column 31 and the connecting seat 32 rotate and move upwards at the same time, that is, the external coil can be wound; after the winding process is completed, the rotation and lifting of the winding column 31 and the connecting seat 32 are stopped, at this time the end of the wire harness is cut off by the cutting assembly 36.

[0073] With reference to Figure 10 The lower pressing cylinder 14 is vertically downward, and the piston rod end of the lower pressing cylinder 14 is fixedly installed with a pushing piece 141, and the bottom end of the pushing piece 141 is provided with a V-shaped groove, so that when the abutting piece 351 in the clamping assembly 35 is in a separated state from the stop block 3213, the lower pressing cylinder 14 drives the pushing piece 141 to move downward, and the pushing piece 141 can push the end of the wire harness to move downward, so that the end of the wire harness moves to between the abutting piece 351 and the stop block 3213, and the abutting piece 351 can be conveniently used to abut and fix the end of the wire harness on the stop block 3213; the V-shaped groove at the bottom end of the pushing piece 141 can play a guiding role, and can avoid the wire harness from being offset to both sides when pushing the wire harness downward.

[0074] With reference to Figure 12 and Figure 13Further, the winding mechanism 3 further comprises a first linear drive 34, which is a pneumatic cylinder. In other embodiments, the first linear drive 34 can also be an electric push rod. The first linear drive 34 is fixedly installed on the support plate 13 of the movable end of the linear module 331 above the machine table 1, and the piston rod of the first linear drive 34 is vertically downward. The end of the piston rod of the first linear drive 34 is fixedly connected with a connecting rod 341, which is vertically arranged and coaxially arranged in the inner hole of the rotating drum 334. The bottom end of the connecting rod 341 is fixedly connected with the top end of the winding column 31. The connecting rod 341 and the rotating drum 334 can slide relative to each other, so that when the connecting rod 341 moves upward relative to the rotating drum 334, the connecting rod 341 can drive the winding column 31 to move upward, and under the limiting action of the bottom end of the rotating drum 334, the coil sleeved on the outer wall of the winding column 31 can be separated from the winding column 31. The connecting rod 341 is fixedly provided with a clamping block, and the inner wall of the rotating drum 334 is provided with a clamping groove, and the clamping block is vertically and slidably connected in the clamping groove, so that the connecting rod 341 and the rotating drum 334 cannot rotate relative to each other, so that when the rotating drum 334 rotates, the connecting rod 341 can be driven to rotate together, thereby driving the winding column 31 to rotate, so that the rotating and lifting assembly 33 can realize the rotating drive of the winding column 31.

[0075] It should be noted that the inner hole diameter of the rotating drum 334 is slightly larger than the diameter of the winding column 31, so that when the first linear drive 34 drives the connecting rod 341 and the winding column 31 to move upward, the winding column 31 can slide into the inner hole of the rotating drum 334, and the coil attached to the outer wall of the winding column 31 cannot slide into the inner hole of the rotating drum 334, so that the separation of the coil and the winding column 31 can be realized. In this application, since the linear module 331 has high precision, the driving of the winding column 31 during the lifting process is realized by the linear module 331, so that the movement amount of the winding column 31 in the vertical direction during the winding process can be accurately controlled, and the winding effect is guaranteed; the movement precision of the ordinary cylinder is low, so that the separation of the winding column 31 and the coil is realized by the cylinder, which can reduce the equipment cost while ensuring the rapid discharging.

[0076] Referring to Figure 5 and Figure 6 , the transfer mechanism 4 is provided with two groups, which are respectively located on both sides of the machine table 1. The transfer mechanism 4 is used for moving the coil to the welding mechanism 5, so that the welding mechanism 5 welds the terminals and the sheet of the coil. Referring to Figure 6The transfer mechanism 4 includes a sliding drive assembly 41, a support plate 42, and a support block 43. The sliding drive assembly 41 includes a first linear motor 411, a second cylinder 412, and a third cylinder 413. The fixed end of the first linear motor 411 is fixedly mounted on the top wall of the machine base 1, and the first linear motor 411 is arranged along the width direction of the machine base 1. The cylinder body of the second cylinder 412 is fixedly connected to the movable end of the first linear motor 411, and the second cylinder 412 is arranged along the length direction of the machine base 1. The cylinder body of the third cylinder 413 is fixedly connected to the piston rod end of the second cylinder body, and the piston rod of the third cylinder 413 is vertically upward. Therefore, with the joint cooperation of the first linear motor 411, the second cylinder 412, and the third cylinder 413, the movable end of the sliding drive assembly 41 can slide in the X-axis, Y-axis, and Z-axis directions.

[0077] In this embodiment, for ease of description, a three-dimensional Cartesian coordinate system is introduced, with the X-axis defined as extending along the width direction of the machine tool 1, the Y-axis defined as extending along the length direction of the machine tool 1, and the Z-axis defined as extending along the height direction of the machine tool 1.

[0078] The support plate 42 is fixedly connected to the piston rod end of the third cylinder 413 via a bracket. The support plate 42 is elongated and horizontal. The support plate 42 is positioned along the width of the machine base 1. The support block 43 is fixedly connected to the support plate 42 by bolts. There are two support blocks 43 arranged at intervals, and each support block 43 corresponds to a winding post 31. A guide protrusion 431 is fixedly provided on the top wall of the support block 43. The guide protrusion 431 can be inserted into the coil from the bottom, thereby guiding and positioning the coil. The side wall of the support block 43 is also provided with two positioning grooves 432 arranged at intervals. The two positioning grooves 432 correspond to the two terminals of the coil, respectively. Therefore, when the coil is inserted outside the guide protrusion 431, the two terminals of the coil are inserted into the two positioning grooves 432 respectively, which can further enhance the positioning effect of the coil and ensure the stable transfer of the coil.

[0079] In this embodiment, the transfer process of the support plate 42 is achieved by one linear motor and two cylinders. In other embodiments, other types of linear drive components can also be used, such as three linear motors or three electric push rods.

[0080] Reference Figure 5The welding mechanism 5 includes a first welding assembly 51, a bending assembly 52, and a second welding assembly 53 sequentially arranged on the machine base 1. A strip of material is threaded through the first welding assembly 51, the bending assembly 52, and the second welding assembly 53. One end of the strip is wound in a strip reel, and the other end is pulled outwards and then conveyed to the welding mechanism 5. A feeding mechanism 15 for conveying the strip is provided on the outer side of the machine base 1. The feeding mechanism 15 mainly includes a motor and a turntable. The motor drives the turntable to rotate through a transmission component, which in turn drives the strip reel mounted on the turntable to rotate, thereby completing the strip conveying process.

[0081] The first welding assembly 51 and the second welding assembly 53 are used to weld the coil terminals to the sheet material on the strip. Both the first welding assembly 51 and the second welding assembly 53 adopt resistance welding. Resistance welding melts the workpiece by means of the resistance heat generated when current passes through the workpiece. The bending assembly 52 includes an upper die, a lower die, and lifting cylinders. There are two lifting cylinders, both vertically fixed to the top wall of the machine base 1. The piston rods of the two lifting cylinders face each other. The upper die is fixedly connected to the end of the piston rod of the upper lifting cylinder, and the lower die is fixedly connected to the end of the piston rod of the lower lifting cylinder. Therefore, under the action of the lifting cylinders, the upper die and the lower die approach each other and press against the sheet material, which can fold the bent part on the sheet material upward and make the bent part cover the outside of the coil terminals, so as to prevent the coil from falling off accidentally during the conveying process, thereby ensuring the processing quality.

[0082] Therefore, before welding the coil and the strip, the sliding drive assembly 41 drives the coil to move below the strip, and then lifts the coil upward, so that the bottom end of the coil is engaged between the corresponding two pieces on the strip. Then, the strip is conveyed to move the coil, and the first welding assembly 51 welds the coil terminals to the pieces on the strip. The current for this welding is small, and only a preliminary fixation is needed. Then, the welded strip is conveyed, and the bending assembly 52 bends the bent part of the piece on the strip upward, so that the bent part covers the outside of the coil terminals. Then, the bent strip is conveyed, and the second welding assembly 53 welds the coil terminals to the pieces on the strip again. The current for this welding is greater than the current for the previous welding, so that the coil and the pieces are firmly connected together.

[0083] The machine table 1 is also provided with a cutting mechanism 16 at the end of the welding mechanism 5, and the cutting mechanism 16 is provided with a feeding mechanism 17 at the end away from the welding mechanism 5. The cutting mechanism 16 can cut the long strip-shaped material into multiple sections through the cutting tool on the cylinder and the cylinder, and then each section of the cut material can be transported to the feeding mechanism 17, and the feeding mechanism 17 can transport the material to the next process and cut the material pieces on the material to form independent coils; then the subsequent forming is carried out to form an inductor.

[0084] The implementation principle of the embodiment 1 is that the coil forming processing device realizes the automatic manufacturing from the enameled wire to the formed inductor coil and the welding fixation with the material piece through the cooperation of multiple mechanisms. The shaping mechanism 7 shapes the wound enameled wire into a straight line, the stripping mechanism 8 strips the outer skin of the enameled wire, the conveying mechanism 2 conveys the wire bundle formed after stripping to the winding mechanism 3, the winding mechanism 3 winds the wire bundle into a coil, and the cutting assembly 36 cuts the end of the wire bundle after winding, so that the wound coil is separated from the wire bundle which has not been wound, and the coil is temporarily attached to the outer wall of the winding column 31 at this time; then the transfer mechanism 4 moves the coil to the welding mechanism 5, the welding mechanism 5 welds the terminals of the coil and the material piece, and then the material with the welded coil is continuously conveyed forward, and finally the cutting of the cutting mechanism 16 can obtain multiple sections of the material, and each section of the material is welded with multiple coils, and then the intermediate product of the material with the welded coil is conveyed to the subsequent process through the feeding mechanism 17.

[0085] Embodiment 2: refer to Figure 14 The difference between the embodiment and the embodiment 1 is that the machine table 1 is also provided with a detection mechanism and an adjusting mechanism 6 in the embodiment, the detection mechanism is used for detecting the position of the wire bundle end, and the adjusting mechanism 6 is used for adjusting the length of the wire bundle over the connecting seat 32. The detection mechanism and the adjusting mechanism 6 cooperate to better control the length of the wire bundle for forming the coil, so that the length of the wire bundle meets the requirements, and the length of the wire bundle is not too short or too long, which affects the subsequent forming effect.

[0086] In the embodiment, the detection mechanism includes an industrial camera, which is fixedly installed on the top of the machine table 1 and located on the side close to the connecting seat 32. The industrial camera can capture the image of the wire bundle end, and the position of the wire bundle end is determined through image processing technology, so as to judge whether the conveying distance of the wire bundle end meets the requirements. Since the position of the cutting assembly 36 is fixed, the position of the wire bundle end after being cut is fixed; the number of winding turns of the wire bundle can also be controlled through the rotating lifting assembly 33; therefore, as long as the conveying distance of the wire bundle end meets the requirements, the initial position of the wire bundle can be kept constant, so that the length of the wire bundle for forming the coil is not too short or too long.

[0087] In other embodiments, the detection mechanism can also be provided as a measuring grating, which can sense the position of the wire bundle end through the shielding of light, so as to determine whether the conveying distance of the wire bundle end meets the requirements, and if so, the winding of the wire bundle end can be performed to form a coil; if not, the wire bundle can be adjusted by the adjusting mechanism 6 until the end of the wire bundle is at the required position.

[0088] The adjusting mechanism 6 is provided in four groups, and each group of the machine table 1 is provided with two groups, which correspond to the two sliding seats 22. Referring to Figure 14 , the adjusting mechanism 6 includes a fifth linear drive 61, a support 63, and a clamping piece 62. The fifth linear drive 61 is a linear motor, which is arranged along the length direction of the machine table 1; the fifth linear drive 61 is fixedly installed on the top wall of the machine table 1, and the fifth linear drive 61 is located on the side of the conveying mechanism 2 away from the winding mechanism 3. The support 63 is fixedly connected to the movable end of the fifth linear drive 61, so that the fifth linear drive 61 can drive the support 63 to slide. The clamping piece 62 is a pneumatic cylinder, the cylinder body of the clamping piece 62 is fixedly connected to the support 63, and the piston rod of the clamping piece 62 is vertically downward. The wire bundle passes between the piston rod of the clamping piece 62 and the support 63, so that the piston rod of the clamping piece 62 extends out to tightly fix the wire bundle on the support 63, so that when the fifth linear drive 61 drives the support 63 to slide, it can drive the wire bundle to move, so that the wire bundle slides along the linear direction of itself until the end of the wire bundle moves to the required position, and then the subsequent winding process is performed. In other embodiments, the clamping piece 62 can also be an electric push rod.

[0089] In the process of driving the wire bundle to move by the adjusting mechanism 6, the end of the piston rod of the fourth linear drive 23 is in a separated state from the sliding seat 22, so that the adjusting mechanism 6 can smoothly drive the wire bundle to move, thereby adjusting the position of the wire bundle end.

[0090] It should be noted that the two sliding seats 22 are fixedly connected, so that the two sliding seats 22 can be driven to move synchronously by one third linear drive 21; when an accident occurs, the moving distances of the wire bundles corresponding to the two sliding seats 22 are different, the corresponding wire bundle can be driven to move by the adjusting mechanism 6, thereby realizing independent adjustment of a certain wire bundle, so that the two wire bundles can be adjusted separately, thereby ensuring the adjustment effect.

[0091] Embodiment 3: Referring to Figure 15The difference between the embodiment and embodiment 1 is that the detection mechanism and the adjusting mechanism 6 are further arranged on the machine table 1 in the embodiment, the detection mechanism is used for detecting the position of the wire harness end, and the adjusting mechanism 6 is used for adjusting the length of the wire harness over the connecting seat 32. The detection mechanism and the adjusting mechanism 6 cooperate with each other, so that the length of the wire harness for forming the coil can be better controlled, so that the length of the wire harness meets the requirements, and the length of the wire harness is prevented from being too short or too long, thereby affecting the subsequent use effect.

[0092] The detection mechanism includes an industrial camera, the industrial camera is fixedly installed on the top of the machine table 1 and located on the side close to the connecting seat 32, the industrial camera can shoot the image of the wire harness end, and the position of the wire harness end is determined through image processing technology, so that whether the conveying distance of the wire harness end meets the requirements is determined. Since the position of the cutting assembly 36 is fixed, the position of the wire harness end cut off is fixed, and the number of winding turns of the wire harness can also be controlled through the rotating and lifting assembly 33. Therefore, only the conveying distance of the wire harness end meets the requirements, the initial position of the wire harness can be kept constant, so that the length of the wire harness for forming the coil is prevented from being too short or too long.

[0093] The adjusting mechanism 6 is provided with four groups, two groups are arranged on each side of the machine table 1 and correspond to the two sliding seats 22 respectively. Referring to Figure 15 The adjusting mechanism 6 includes a pneumatic finger 64, a cutter 65 and a bottom plate 66. The pneumatic finger 64 is fixedly connected to the top wall of the machine table 1, and the active end of the pneumatic finger 64 slides in the vertical direction. The cutter 65 is fixedly connected to one of the active ends of the pneumatic finger 64, and the bottom plate 66 is fixedly connected to the other active end of the pneumatic finger 64. The cutting edge of the cutter 65 and the bottom plate 66 slide in the vertical direction and can abut each other. Therefore, only a certain distance of the wire harness is conveyed slightly forward, so that the end of the wire harness overcomes the cutter 65, and then the pneumatic finger 64 drives the cutter 65 and the bottom plate 66 to abut each other, so that the end of each wire harness is kept in the same position, thereby ensuring the conveying accuracy of the wire harness.

[0094] Further, the pneumatic finger 64 is detachably fixedly connected to the top wall of the machine table 1 through bolts, so that the installation position of the pneumatic finger 64 can be adjusted as required, which is more convenient.

[0095] The above is an optional embodiment of the application, which does not limit the protection scope of the application, therefore: any equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
