Description

Technical Field

[0001] This invention relates to the field of coil forming technology, and more particularly to a winding machine. Background Technology

[0002] Traditional winding machines typically only have the function of winding to form coils. However, in the coil forming process of coreless motors, after winding, the coil still needs to undergo processes such as flattening, flattening and heating, rounding, and tinning. These different processes require transferring and switching the coil between different machines, making it difficult to effectively improve the overall operation. Therefore, there is an urgent need for a more seamless winding process to improve coil production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a winding machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this invention is: A winding machine includes: a winding device having a rotatable winding die; a shaping device having two hot pressing dies that can move closer to or further away from each other; a wire taking device having a wire taking clamp movable between the winding die and the two hot pressing dies; a rounding device including a die core and a rounding die that can move closer to or further away from the die core, the rounding die having a plurality of dies arranged around the die core; a first transfer device including a first transfer clamp that can enter or exit between the two hot pressing dies, a second transfer clamp movable between the first transfer clamp and the die core, and a lever rotatable around the die core; a soldering device including a solder pot and a soldering fixture, the soldering fixture being rotatable closer to or further away from the solder pot; and a second transfer device having a third transfer clamp movable between the die core and the soldering fixture.

[0005] This technical solution has at least the following beneficial effects: During operation, the winding is rotated outside the winding mold to form a coil. Then, the take-up clamp in the take-up device approaches the winding mold and takes out the coil outside the winding mold. The coil is flattened and then moved between two hot pressing molds. The two hot pressing molds heat and press the coil to flatten and shape it, and eliminate stress rebound. After hot pressing is completed, the first transfer clamp in the first transfer device enters between the two hot pressing molds and clamps the coil. Then, the two hot pressing molds move away from each other and are released. At this time, the coil can be moved out between the two hot pressing molds. The second transfer clamp moves closer to the first transfer clamp, clamps out the coil in the first transfer clamp, and transfers it to the outside of the mold core. Then, the pressing mold moves closer to the mold core and presses one side of the coil to shape it on the mold core. On the outside, the coil is rotated around the mold core starting from the position where the coil is pressed against the mold core, so that the coil bends around the mold core. Multiple rounding molds are brought close to the outside of the mold core in sequence along the circumference of the mold core to complete the rounding of the coil along the circumference of the mold core. Then, the third transfer clamp in the second transfer device approaches the mold core, takes out the coil formed on the outer circumference of the mold core upward, and transfers it to the tinning fixture for positioning. Rotating the tinning fixture can bring the coil close to the tin pot for tinning. After completion, the tinning fixture is reversed to reset. In this way, the coil can automatically complete the flattening, flattening heating, rounding and tinning processes after winding, reducing manual intervention, saving the time of transferring the coil between different devices, and greatly improving the efficiency of coil winding and forming.

[0030] Reference Figure 1A winding machine includes a winding device 100, a shaping device 200, a wire taking device 300, a rounding device 400, a first transfer device 500, a tinning device 600, and a second transfer device 700. The winding device 100 has a rotatable winding mold 130; the shaping device 200 has two hot-pressing molds 210 that can move closer to or further away from each other; the wire taking device 300 has a wire taking clamp that can move between the winding mold 130 and the two hot-pressing molds 210; the rounding device 400 includes a mold core 410 and a rounding mold 420 that can move closer to or further away from the mold core 410. The hot press mold 420 is provided with a plurality of components surrounding the mold core 410; the first transfer device 500 includes a first transfer clamp 510 that can enter or exit between the two hot press molds 210, a second transfer clamp 520 that can move between the first transfer clamp 510 and the mold core 410, and a lever 530 that can rotate around the mold core 410; the soldering device 600 includes a solder pot 610 and a soldering fixture, the soldering fixture being rotatable toward or away from the solder pot 610; the second transfer device 700 has a third transfer clamp 710 that can move between the mold core 410 and the soldering fixture.

[0031] As described above, during operation, the winding die 130 rotates to form a coil. Then, the take-up clamp in the take-up device 300 approaches the winding die 130, takes out the coil from the outside of the winding die 130, flattens the coil, and moves it between the two hot pressing dies 210. The two hot pressing dies 210 heat and press the coil to flatten and shape it, and eliminate stress rebound. After hot pressing, the first transfer clamp 510 in the first transfer device 500 enters between the two hot pressing dies 210 and clamps the coil. Then, the two hot pressing dies 210 move away from each other and are released. At this time, the coil can be moved out between the two hot pressing dies 210. The second transfer clamp 520 moves closer to the first transfer clamp 510, clamps out the coil in the first transfer clamp 510, and transfers it to the outside of the die core 410. Then, the pressing die 420 moves closer to the die core 410 and presses one side of the coil to shape it on the die core 410. 10. On the outside, the lever 530 starts from the position where the coil is pressed against the mold core 410 and rotates the coil around the mold core 410, so that the coil is bent around the mold core 410. Multiple rounding molds 420 are brought close to the outside of the mold core 410 in sequence along the circumference of the mold core 410 to complete the rounding of the coil along the circumference of the mold core 410. Then, the third transfer clamp 710 in the second transfer device 700 approaches the mold core 410, takes the coil formed on the outer circumference of the mold core 410 upward, and transfers it to the tinning fixture for positioning. Rotating the tinning fixture can bring the coil close to the tin pot 610 for tinning. After completion, the tinning fixture is reversed and reset. In this way, the coil can automatically complete the flattening, flattening heating, rounding and tinning processes after winding, reducing manual intervention, saving the time of transferring the coil between different devices, and greatly improving the efficiency of coil winding and forming.

[0032] The wire take-up clamp can remove and flatten the coil located outside the winding mold 130. It has various structural forms. In this embodiment, the wire take-up clamp includes a wire take-up base 311, a wire take-up drive 312, a rack, a transmission gear 313, and clamping rods 314. Two clamping rods 314 are slidably connected to the wire take-up base 311 in the left-right direction, and two sliders 315 are slidably connected to the two clamping rods 314 in the front-back direction. The transmission gear 313 is rotatably connected to the wire take-up base 311. The wire take-up drive 312 is induced to drive the rack, allowing it to move back and forth. The wire take-up drive 312 can be driven by a cylinder, electric screw, or hydraulic cylinder. The rack meshes with the transmission gear 313. Connecting rods 316 are connected to the left and right sides of the transmission gear 313 on the rotation axis, and two connecting rods 316 are rotatably connected to two sliders 315. When the wire take-up clamp needs to clamp both sides of the coil, the wire take-up drive 312 drives the rack to move, and the rack transmits power to the transmission gear 313, thereby driving the two connecting rods 316 on the transmission gear 313 to rotate around the axis of the transmission gear 313. When the two connecting rods 316 rotate from the left and right sides of the axis of the transmission gear 313 to the front and rear sides of the axis of the transmission gear 313, the two connecting rods 316 can drive the two clamping rods 314 to move closer to each other, thereby achieving the following: first lightly clamp both sides of the coil, and after the coil is released from the winding mold 130, the clamping force is increased to flatten the coil. After completion, the wire take-up drive 312 drives the rack to move in the opposite direction, causing the transmission gear 313 to reverse, thereby driving the two clamping rods 314 to move away from each other.

[0033] Since the wire take-up clamp needs to remove the coil from the outside of the winding mold 130, it is natural that the wire take-up device 300 has a drive structure that can drive the wire take-up clamp to move. Specifically, the wire take-up device 300 includes a wire take-up horizontal movement drive, a wire take-up vertical movement drive, and a wire take-up slide plate. The wire take-up vertical movement drive is set on the wire take-up horizontal movement drive and can drive the wire take-up vertical movement drive to move left and right. The wire take-up slide plate is set on the wire take-up vertical movement drive and can drive the wire take-up slide plate to move back and forth. The wire take-up horizontal movement drive and the wire take-up vertical movement drive can be driven by a cylinder, an electric screw, or a hydraulic cylinder, etc. The wire take-up base 311 is connected to the wire take-up slide plate. During operation, the wire take-up longitudinal movement drive moves the wire take-up slide forward, which moves the wire take-up clamp closer to the winding mold 130. Then, the wire take-up slide slide backward, which moves the wire take-up clamp to remove the wound coil from the winding mold 130. Then, the wire take-up lateral movement drive moves the wire take-up clamp to move the coil to face the shaping device 200. Finally, the wire take-up longitudinal movement drive moves the wire take-up clamp to move the coil between the two hot pressing molds 210, realizing the removal, flattening and transfer of the coil.

[0034] The wire taking device 300 also has a structure for clamping and positioning the wire ends of the coil. Specifically, the wire taking device 300 includes a wire end clamping drive 321 and wire clamping plates 322. The wire end clamping drive 321 is connected to the wire taking base 311 and is driven by two wire clamping plates 322. The wire end clamping drive 321 can drive the two wire clamping plates 322 to move closer or further apart. The wire end clamping drive 321 can be a cylinder, electric lead screw, or hydraulic cylinder, etc. In practical applications, the wire end clamping drive 321 is mounted on the wire taking slide plate and can move back and forth with the wire taking slide plate. When it is necessary to remove the wound coil from the winding mold 130, the wire end clamping drive 321 drives the two wire clamping plates 322 to move closer together, clamping multiple wire ends on the top side of the coil. This helps to shape multiple wire ends and prevents the wire ends from shifting during the movement.

[0035] As a specific structural embodiment of the shaping device 200, the shaping device 200 includes a shaping drive 220, which is connected to two hot pressing molds 210. The shaping drive 220 can be a pneumatic gripper or an electric gripper. The shaping drive 220 can drive the two hot pressing molds 210 to move closer or further away from each other. On the side of the two hot pressing molds 210 facing each other, there are respectively provided a clearance through groove 211 that can avoid the wire take-up clamp and the first transfer clamp 510. When the take-up clamp moves between the two hot pressing molds 210, the take-up clamp is directly opposite the clearance slots 211 on the two hot pressing molds 210. At this time, the two hot pressing molds 210 approach each other to heat-press and shape the coil without interfering with the two clamping rods 314 of the take-up clamp. Then the two clamping rods 314 move away from each other to loosen the clamping of the coil and move out of the clearance slots 211. After the heat pressing and shaping of the coil is completed, the first transfer clamp 510 extends into the clearance slots 211 to clamp the coil, while the two hot pressing molds 210 move away from each other to release the clamping of the coil. At this time, the second transfer clamp 520 can move close to the coil and clamp the top position of the coil, thereby transferring the coil to the next station.

[0036] As a specific embodiment of the first transfer device 500, the first transfer device 500 includes a first longitudinal drive, a second longitudinal drive, a first transverse drive, and a first lifting drive. The first transfer clamp 510 is disposed on the first longitudinal drive, which can drive the first transfer clamp 510 to move closer to or further away from the two hot press molds 210. The first transverse drive is disposed on the second longitudinal drive, which can drive the first transverse drive to move back and forth. The first lifting drive is disposed on the first transverse drive, which can drive the first lifting drive to move left and right. The first transfer clamp 510 is disposed on the first lifting drive, which can drive the first transfer clamp 510 to move up and down. In practical applications, the first longitudinal drive, the second longitudinal drive, the first transverse drive, and the first lifting drive can all be driven by a cylinder, a hydraulic cylinder, or an electric screw, etc. During operation, the second longitudinal drive, the first transverse drive, and the first lifting drive provide driving forces for the second transfer clamp 520 to move forward, backward, left, right, and up and down, respectively, thereby enabling the first transfer clamp 510 to move between the second transfer clamp 520 and the mold core 410.

[0037] The first transfer device 500 may have an independent drive source for moving the lever 530, or it may share a drive structure with the second transfer clamp 520. Specifically, the first transverse drive is equipped with a telescopic drive, which is connected to the lever 530. The telescopic drive can be a cylinder, an electric screw, or a hydraulic cylinder. During operation, when the second transfer clamp 520 is needed, the telescopic drive moves the lever 530 upward to avoid the lever 530 interfering with the movement of the second transfer clamp 520. When the lever 530 is needed, the second transfer clamp 520 moves upward, while the telescopic drive moves the lever 530 downward. The second longitudinal drive and the first transverse drive provide driving force for the lever 530 to move forward, backward, left, and right, thereby causing the lever 530 to rotate around the outer circumference of the mold core 410.

[0038] The second transfer device 700 includes a drive structure that can move the third transfer clamp 710. Specifically, the second transfer device 700 includes a second lateral drive and a second lifting drive. The second lifting drive is mounted on the second lateral drive and can move the second lifting drive left and right. The third transfer clamp 710 is mounted on the second lifting drive and can move the third transfer clamp 710 up and down. In practical applications, both the second lateral drive and the second lifting drive can be cylinders, electric lead screws, or hydraulic cylinders. During operation, the second lateral drive and the second lifting drive provide driving forces to the third transfer clamp 710 for left-right and up-down movement, respectively, thereby causing the third transfer clamp 710 to move back and forth between the mold core 410 and the soldering fixture.

[0039] After the coil is rounded, the wire ends at both ends need to be twisted. Therefore, in this embodiment, the second transfer device 700 is equipped with a twisting clamp 720 that can move close to or away from the mold core 410. The twisting clamp 720 can rotate around an axis in the vertical direction. The twisting clamp 720 moves to the mold core 410, clamps the two wire ends at both ends, and twists them, which further improves the convenience of coil processing and forming. In addition, a wire cutting clamp can be provided on the side of the mold core 410. After the wire ends are twisted and formed, the wire cutting clamp moves to the twisted wire ends to trim and shape them.

[0040] In practical applications, a third lifting drive is also provided on the second lateral movement drive. The second lateral movement drive can drive the third lifting drive to move left and right. The third lifting drive is equipped with a twisting motor, which can drive the twisting motor to move up and down. The third lifting drive can be a cylinder, electric lead screw, or hydraulic cylinder, etc. The twisting motor is connected to the twisting clamp 720. During operation, the second lateral movement drive and the third lifting drive drive the twisting clamp 720 to move left and right and up and down, and the twisting motor drives the twisting clamp 720 to rotate.

[0041] As a specific embodiment of the soldering fixture, the soldering fixture includes a rotary drive 620, a rotating frame 630, a positioning drive, and a positioning block 640. The rotating frame 630 has a positioning groove on its top side. The rotary drive 620 is connected to the rotating frame 630 and can drive the rotating frame 630 to rotate, causing the positioning groove to face upwards or towards the solder pot 610. The positioning drive is disposed on the rotating frame 630 and is connected to the positioning block 640. The positioning drive can drive the positioning block 640 to move closer to or away from the positioning groove. In practical applications, the rotary drive 620 can be a rotary cylinder or a motor, while the positioning drive can be a cylinder, an electric lead screw, or a hydraulic cylinder. The third transfer clamp 710 transfers the coil to the positioning groove on the top side of the rotating frame 630. The positioning groove limits the coil. Then, the positioning drive moves the positioning block 640 closer to the positioning groove, so that the positioning block 640 abuts against the outside of the coil, improving the positioning effect of the coil. Next, the rotation drive 620 drives the rotating frame 630 to rotate, so that the end of the coil is immersed in the solder pot 610 for soldering. After completion, the rotation drive 620 drives the rotating frame 630 to reverse and reset. In this way, the coil can be automatically soldered.

[0042] The winding device 100 is mainly used to form coils. In this embodiment, the winding device 100 includes a winding mechanism, a lead wire mechanism, a hook wire mechanism, a side pressing mechanism, and an upper pressing mechanism. The winding mechanism has a rotating base 110 that can rotate about a horizontal axis. The rotating base 110 is provided with a wire clamping part 120 and a winding mold 130. An openable and closable wire clamping space is formed in the wire clamping part 120. The lead wire mechanism has a lead wire frame 141 that can move between the wire clamping part 120 and the winding mold 130. A lead wire nozzle 142 is provided on the bottom side of the lead wire frame 141. The hook wire mechanism has a lead wire nozzle that can... The hook 151 that moves between the lead tip 142 and the winding mold 130; the side pressing mechanism is provided with side pressing seats 161 on the left and right sides of the winding mold 130 respectively; the two side pressing seats 161 can be close to or away from the winding mold 130 respectively; the side of the two side pressing seats 161 close to the winding mold 130 is respectively connected to a side pressing block 162; at least one side pressing seat 161 is connected to a wire cutter 163; the upper pressing mechanism has a chuck 171 that can move close to or away from the top side of the winding mold 130; the chuck 171 has an openable clamping space.

[0043] In the winding device 100, the wire to be wound is fed to the lead nozzle 142 on the bottom side of the lead frame 141, and the wire extends from the bottom end of the lead nozzle 142. The lead nozzle 142 can be moved to the clamping part 120, opening the clamping space inside the clamping part 120. The wire is placed into the clamping space, and then the clamping part 120 clamps the wire. At this time, moving the lead nozzle 142 can pull the wire to the winding mold 130. The rotating base 110 rotates, causing the winding mold 130 to rotate, thereby realizing the winding of the wire on the winding mold 130. During the winding process, after the set number of turns, the hook 151 moves between the lead tip 142 and the winding die 130, hooks the wire, and moves below the winding die 130. The hook 151 rotates, twisting the wire into a head on the coil. Then, the hook 151 retracts the head, and the winding die 130 rotates to continue winding the wire onto it. This process is repeated to create multiple head shapes on the coil during winding. Once the coil is wound, the lead tip 142 moves past the wire cutter to cut the wire. The wire clamp and head clamp are then removed. Approaching the winding mold 130, the wire take-up clamp clamps the two sides of the coil wound on the outside of the winding mold 130, while the wire end clamp clamps the formed wire end on the outside of the winding mold 130. Since the wire take-up clamp and wire end clamp have adhesive force at the point where they abut against the coil, to ensure that the wire take-up clamp and wire end clamp can be firmly attached to the outside of the coil, two side pressure seats 161 in the side pressure mechanism approach the winding mold 130 respectively, causing two side pressure blocks 162 to abut against the two sides of the wire take-up clamp, further clamping the wire take-up clamp to the two sides of the coil. Meanwhile, the clamp head 171... The wire end clamp is tightened on both sides, further clamping the wire end clamp to both sides of the wire end, thereby ensuring full contact between the wire take-up clamp and the coil, and between the wire end clamp and the wire end. Then, the two side pressure seats 161 move away from the winding mold 130 respectively, and the clamping head 171 also opens the clamping space. The wire take-up clamp and the wire end clamp jointly bring the coil out of the winding mold 130 through adhesive force. In this way, the wire can be automatically wound by rotating the winding mold 130, and the wire end can be automatically twisted on the coil to form a wire end, reducing manual intervention and greatly improving winding efficiency and quality.

[0044] The wire clamping part 120 on the rotary seat 110 is mainly used for clamping the wire. It has various structural forms. In this embodiment, the wire clamping part 120 includes a wire clamping sleeve, a movable rod, a wire clamping block, a spring, and a wire clamping drive. The wire clamping sleeve is connected to the rotary seat 110. One end of the movable rod passes through the wire clamping sleeve and is connected to the wire clamping block. The other end of the movable rod passes through the rotary seat 110 and forms a limiting shoulder. The spring is sleeved on the outside of the movable rod. The two ends of the spring abut against the limiting shoulder and the rotary seat 110, respectively. The spring can drive the movable rod to move closer to the wire clamping drive through the limiting shoulder, so that the wire clamping block abuts against the end of the wire clamping sleeve. The wire clamping drive is connected to a top pressure member. The wire clamping drive can drive the top pressure member to abut against or move away from the limiting shoulder. In practical applications, the wire clamping drive can be a cylinder, an electric lead screw, or a hydraulic cylinder, etc. When the wire clamping drive is not working, the top pressure component is away from the limit shoulder. At this time, the spring drives the movable rod to move closer to the wire clamping drive through the limit shoulder, so that the wire clamping block abuts against the end of the wire clamping sleeve, maintaining the clamping state of the wire. When it is necessary to loosen the clamping of the wire, the wire clamping drive is working, driving the top pressure component to abut against the limit shoulder, and pushing the movable rod through the limit shoulder, driving the wire clamping block away from the end of the wire clamping sleeve, thereby loosening the wire.

[0045] To better control the loosening and releasing of the wire, in this embodiment, the wire guide frame 141 is provided with a wire guide wheel 143, a wire pressing drive 144, and a fixing block 145. The wire guide wheel 143 is located above the fixing block 145. The wire pressing drive 144 is connected to the wire pressing block. The wire pressing drive 144 can drive the wire pressing block to move closer to or away from the fixing block 145. In practical applications, the wire pressing drive 144 can be a cylinder, an electric lead screw, or a hydraulic cylinder, etc. The wire to be wound passes through the lead roller 143, which guides and stabilizes the wire. Then it is pulled between the fixed block 145 and the pressure block, and then passes through the lead nozzle 142. During operation, if the wire needs to be released for winding, the pressure drive 144 drives the pressure block away from the fixed block 145, releasing the clamping force on the wire. When the lead nozzle 142 needs to move the wire, the pressure drive 144 drives the pressure block closer to the fixed block 145 to press the wire. At this time, the lead nozzle 142 can move the wire more stably.

[0046] The winding mechanism includes a drive structure that can rotate the winding die 130. Specifically, the winding mechanism includes a first motor and a transmission sleeve 111. The first motor is driven by the transmission sleeve 111 and can drive the transmission sleeve 111 to rotate. The rotating base 110 is connected to the transmission sleeve 111. The first motor provides a rotational driving force to the transmission sleeve 111, thereby driving the winding die 130 on the rotating base 110 to rotate. In practical applications, the first motor and the transmission sleeve 111 can transmit power through a synchronous pulley and a synchronous belt. Specifically, a first synchronous pulley is driven by the first motor, a second synchronous pulley is provided on the outside of the transmission sleeve 111, and a synchronous belt connects the first and second synchronous pulleys.

[0047] After the coil is wound around the outside of the winding mold 130, in order to facilitate the removal of the coil from the winding mold 130, in this embodiment, the winding mechanism further includes a push-pull drive, a transmission rod 112, and a wedge rod 113. The winding mold 130 includes an upper mold 131 and a lower mold 132 that are slidably connected to the rotating base 110 in the vertical direction. The push-pull drive is connected to the transmission rod 112. The push-pull drive can be a drive source such as a cylinder, an electric screw, or a hydraulic cylinder. The push-pull drive can drive the transmission rod 112 to move along the shaft of the transmission sleeve 111 within the transmission sleeve 111. The transmission rod 112 passes through the transmission sleeve 111 and is connected to the wedge rod 113. 3. Located between the upper mold 131 and the lower mold 132, the top and bottom surfaces of the wedge rod 113 are inclined towards each other in a direction away from the transmission rod 112. An upper elastic element 114 is provided between the rotating seat 110 and the upper mold 131. The upper elastic element 114 presses the upper mold 131 against the top surface of the wedge rod 113. A lower elastic element 115 is provided between the rotating seat 110 and the lower mold 132. The lower elastic element 115 presses the lower mold 132 against the bottom surface of the wedge rod 113. The upper elastic element 114 and the lower elastic element 115 are mainly used to provide elastic force in the vertical direction and can be springs, torsion springs or other elastic structural components. When winding is required on the winding die 130, the push-pull drive moves the wedge rod 113 away from the drive rod 112 via the transmission rod 112. Since the top and bottom surfaces of the wedge rod 113 are inclined away from the drive rod 112, the wedge rod 113 guides the upper die 131 and lower die 132 to slide upwards and downwards respectively, causing the upper elastic element 114 and lower elastic element 115 to further deform elastically. At this point, the upper die 131 and lower die 132 are in a state of mutual separation, forming the internal cavity shape of the wound coil. When the coil is wound, the pull drive drives the wedge rod 113 to move closer to the drive rod 112 via the transmission rod 112. At this time, the top and bottom surfaces of the wedge rod 113 reduce the top pressure on the upper mold 131 and the lower mold 132 in the vertical direction. The upper elastic element 114 and the lower elastic element 115 can push the upper mold 131 and the lower mold 132 closer to the wedge rod 113 respectively, so that the upper mold 131 and the lower mold 132 move closer to each other, and the top pressure on the inside of the coil is removed. In this way, the coil can be easily removed from the winding mold 130.

[0048] The hooking mechanism includes a drive structure that can move or rotate the hook 151. Specifically, the hooking mechanism includes a forward and backward translation drive, a hook lateral movement drive 152, a hook lifting drive 153, and a second motor 154. The hook lateral movement drive 152 is mounted on the forward and backward translation drive and can move the hook lateral movement drive 152 forward and backward. The hook lifting drive 153 is mounted on the hook lateral movement drive 152 and can move the hook lifting drive 153 left and right. The second motor 154 is mounted on the hook lifting drive 153 and can move the second motor 154 up and down. The second motor 154 is connected to the hook 151 and can drive the hook 151 to rotate around an axis in the up and down direction. In practical applications, the forward and backward translation drive, the hook lateral movement drive 152, and the hook lifting drive 153 can be driven by electric screws, cylinders, or hydraulic cylinders. During operation, the forward and backward translation drive, the hook line lateral movement drive 152, and the hook line lifting drive 153 can respectively provide driving force to the hook 151 in the forward, backward, left and right, and up and down directions, so that the hook 151 moves closer to the lead wire nozzle 142, hooks the wire and moves it to the bottom of the winding mold 130. Then the second motor 154 works to wind the wire that has been hooked to the bottom of the winding mold 130 to form a wire end. During this process, the hook line lifting drive 153 can drive the hook 151 to move upward for fine adjustment, thereby compensating for the amount of tightening of the wire when winding it and preventing the wire from being torn. After completion, the hook 151 is driven to withdraw the wire end.

[0049] The lead-in mechanism has a drive structure that can move the lead-in nozzle 142. This drive structure can be independent of the drive structure in the hook-in mechanism. However, to reduce the number of drive sources, the lead-in mechanism and the hook-in mechanism can share some drive sources. Specifically, the lead-in mechanism includes a lead-in horizontal movement drive 146 and a lead-in lifting drive 147. The lead-in horizontal movement drive 146 is mounted on the front-to-back translation drive, which can move the lead-in horizontal movement drive 146 back and forth. The lead-in lifting drive 147 is mounted on the lead-in horizontal movement drive 146, which can move the lead-in lifting drive 147 left and right. The lead-in frame 141 is mounted on the lead-in lifting drive 147, which can move the lead-in frame 141 up and down. In practical applications, the lead-in horizontal movement drive 146 and the lead-in lifting drive 147 can use drive sources such as cylinders, electric screws, or hydraulic cylinders. The forward and backward translation drive, the lead wire lateral movement drive 146, and the lead wire lifting drive 147 can respectively drive the lead wire frame 141 to move in the forward, backward, left and right, and up and down directions, thereby adjusting the position of the lead wire nozzle 142.

[0050] When the hooking mechanism and the lead-in mechanism share a single forward and backward translational drive for power, in order to achieve independent driving force for the hook 151 or lead-in tip 142 to move in the forward and backward direction and reduce the driving load, in this embodiment, the forward and backward translational drive includes a first sliding group 155, a translational drive source 156, and a second sliding group 157. The translational drive source 156 is driven by a first pressure block 158 and a second pressure block 159. The translational drive source 156 can drive the first pressure block 158 and the second pressure block 159 to move back and forth. The translational drive source 156 can be a cylinder, an electric lead screw, or a hydraulic cylinder, etc. The first sliding group 155 has a first sliding plate that can be elastically moved forward, and the hooking lateral movement drive 152 is disposed on the first sliding plate. The hook line lateral movement drive 152 is provided with a first transmission block that can move closer to or away from the first pressure block 158. In practical applications, the hook line lateral movement drive 152 is provided with a drive source such as a cylinder, electric screw, or hydraulic cylinder to drive the first transmission block closer to or away from the first pressure block 158. The second sliding group 157 has a second sliding plate that can move forward elastically. The lead wire lateral movement drive 146 is provided on the second sliding plate. The lead wire lateral movement drive 146 is provided with a second transmission block that can move closer to or away from the second pressure block 159. In practical applications, the lead wire lateral movement drive 146 is provided with a drive source such as a cylinder, electric screw, or hydraulic cylinder to drive the second transmission block closer to or away from the second pressure block 159.The first slide plate in the first sliding assembly 155 can slide in the front-to-back direction. Due to its internal elastic structure, the first slide plate can move forward to the end of its stroke without external force. Similarly, the second slide plate in the second sliding assembly can slide in the front-to-back direction. Due to its internal elastic structure, the second slide plate can move forward to the end of its stroke without external force. When it is necessary to move the hook 151 backward, the first transmission block on the first slide plate approaches and abuts against the first pressure block 158. At this time, the translation drive source 156 drives the first pressure block 158 and the second pressure block 159 to move backward simultaneously. Since the first pressure block 158 and the first transmission block are in contact with each other, power can be transmitted to the first slide plate synchronously, causing the hook 151 to move backward. When the translation drive source 156 drives the first pressure block 158 and the second pressure block 159 to move backward simultaneously, the first transmission block 158 and the second pressure block 159 can move backward simultaneously. When the first slide plate moves forward, it moves forward under the action of elastic force, causing the hook 151 to move forward and maintaining the contact between the first pressure block 158 and the first transmission block. Similarly, when it is necessary to drive the lead tip 142 to move backward, the second transmission block on the second slide plate approaches and abuts against the second pressure block 159. At this time, the translation drive source 156 drives the first pressure block 158 and the second pressure block 159 to move backward at the same time. Since the second pressure block 159 and the second transmission block are in contact with each other, the power can be transmitted to the second slide plate in a synchronized manner, causing the lead tip 142 to move backward. When the translation drive source 156 drives the first pressure block 158 and the second pressure block 159 to move forward, the second slide plate moves forward under the action of elastic force, causing the lead tip 142 to move forward and maintaining the contact between the second pressure block 159 and the second transmission block.

[0051] The first sliding assembly 155 mainly has an elastic structural component that pushes the first slide plate to maintain a forward movement tendency. Specifically, the first sliding assembly 155 includes a first slide block and a first elastic component. The first slide plate is slidably connected to the first slide block in the front-back direction. The first elastic component is disposed between the first slide block and the first slide plate. The first elastic component tends to push the first slide plate forward to the end of its stroke. The first elastic component can be an elastic structure such as a spring or a spring rod. When the first pressure block 158 pushes the first transmission block backward, it can drive the first slide plate to move backward and cause the first elastic component to further deform elastically. When the first pressure block 158 removes the pressure on the first transmission block, the first slide plate moves forward under the elastic force of the first elastic component. Similarly, the second sliding assembly 157 mainly has an elastic structural component that pushes the second slide plate to maintain a forward movement tendency. Specifically, the second sliding assembly 157 includes a second slide block and a second elastic component. The second slide plate is slidably connected to the second slide block in the front-back direction. The second elastic component is disposed between the second slide block and the second slide plate. The second elastic component tends to push the second slide plate forward to the end of its stroke. The second elastic component can be an elastic structure such as a spring or a spring rod. When the second pressure block 159 pushes the second transmission block backward, it can drive the second slide plate to move backward and cause the second elastic component to further deform elastically. When the second pressure block 159 removes the pressure on the second transmission block, the second slide plate moves forward under the elastic force of the second elastic component.

[0052] The inner side of the side-pressure mechanism has a drive source that can drive the two side-pressure seats 161 to move left and right. Specifically, the side-pressure mechanism includes two side-pressure drives 164 and two slide rods 165. The two side-pressure drives 164 respectively drive the two slide rods 165 to move left and right. The two side-pressure seats 161 are respectively connected to the two slide rods 165. The side-pressure drives 164 can be driven by a cylinder, an electric lead screw, or a hydraulic cylinder. The two slide rods 165 are slidably connected to the fixed structure of the external device, which can improve the stability of the movement. The two side-pressure drives 164 drive the two slide rods 165 to move left and right, thereby causing the side-pressure seats 161 on the two slide rods 165 to move closer to or away from the winding mold 130. In practical applications, the two slide rods 165 are staggered in the vertical direction to improve space utilization.

[0053] The pressing mechanism has a drive structure that can move the chuck 171. Specifically, the pressing mechanism includes a pressing longitudinal drive 172 and a pressing lifting drive 173. The pressing lifting drive 173 is disposed on the pressing longitudinal drive 172. The pressing longitudinal drive 172 can drive the pressing lifting drive 173 to move back and forth. The pressing lifting drive 173 is connected to the chuck 171 and can drive the chuck 171 to move up and down. The pressing longitudinal drive 172 and the pressing lifting drive 173 can be driven by a cylinder, an electric lead screw or a hydraulic cylinder or other drive source. The upper pressure longitudinal movement drive 172 and the upper pressure lifting drive 173 can respectively provide driving force for the chuck 171 to move in the front-back and up-down directions. When the external wire end clamp clamps the wire end on the top side of the coil, the upper pressure longitudinal movement drive 172 and the upper pressure lifting drive 173 provide driving force for the chuck 171 to move to both sides of the wire end clamp, and then further press the two sides of the wire end clamp to ensure that the wire end clamp and the wire end are in full contact. After completion, the chuck 171 is driven to return to the reset position.

[0054] To ensure that the wire can be removed from the clamping part 120 when the coil is removed, in this embodiment, a pusher plate 166 is connected to one of the side pressure seats 161. The pusher plate 166 forms a pusher groove at a position below the clamping space. The wire being fed from the clamping part 120 to the winding mold 130 is aligned with the pusher groove. When the side pressure seat 161 approaches the winding mold 130, the pusher plate 166 can drive the wire to move, causing the wire to leave the clamping part 120, thereby improving the smoothness of removing the coil from the winding mold 130.
