Description

Technical Field

[0001] This utility model relates to the field of coil forming technology, and in particular to a winding device. Background Technology

[0002] Traditional single-axis winding machines have low automation levels and are only suitable for winding micro-coils, resulting in low production efficiency. While multi-axis winding machines have emerged to increase output per unit time, these machines suffer from inconsistent winding accuracy across different stations due to the cumulative mechanical errors caused by multi-axis synchronous motion. This leads to problems in areas such as turn count consistency, wire uniformity, and tension stability, making it difficult to meet the high-precision requirements for coil production. Therefore, there is an urgent need for a production device with higher winding efficiency and accuracy. Utility Model Content

[0003] The purpose of this utility model is to provide a winding device 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 utility model is: A winding device includes: a winding mechanism having a rotating base rotatable about a horizontal axis, the rotating base having a wire clamping part and a winding mold, the wire clamping part having an openable and closable wire clamping space; a wire guiding mechanism having a wire guiding frame movable between the wire clamping part and the winding mold, the bottom side of the wire guiding frame having a wire guiding nozzle; a wire hooking mechanism having a hook needle movable between the wire guiding nozzle and the winding mold; a side pressing mechanism having side pressing seats respectively located on the left and right sides of the winding mold, the two side pressing seats being respectively close to or away from the winding mold, the side of the two side pressing seats close to the winding mold being respectively connected to a side pressing block, at least one of the side pressing seats being connected to a wire cutting knife; and an upper pressing mechanism having a chuck movable close to or away from the top side of the winding mold, the chuck having an openable and closable clamping space.

[0005] This technical solution has at least the following beneficial effects: The wire to be wound is fed to the lead nozzle on the bottom side of the lead frame, and the wire extends from the bottom end of the lead nozzle. The lead nozzle can be moved to the clamping part, opening the clamping space inside the clamping part. The wire is placed into the clamping space and then clamped by the clamping part. At this time, moving the lead nozzle can pull the wire to the winding mold. The turntable rotates, causing the winding mold to rotate, thus realizing the winding of the wire on the winding mold. After the set number of turns, the hook moves between the lead nozzle and the winding mold, hooks the wire, and moves to the bottom of the winding mold. The hook rotates and twists the wire into a head on the coil. Then the hook retracts the head, the winding mold rotates, and continues to wind the wire on the winding mold. This process is repeated, which can form multiple heads on the coil during winding. After the coil is wound, the lead nozzle moves past the wire cutter to cut the wire. The external wire take-up clamp and wire head clamp approach the winding mold to take the wire. The clamps hold the coil wound on both sides of the winding mold, while the wire end clamps hold the wire end formed on the outside of the winding mold. Since the wire take-up clamp and the wire end clamp have adhesive force at the position where they abut against the coil, in order to ensure that the wire take-up clamp and the wire end clamp can be firmly attached to the outside of the coil, two side pressure seats in the side pressure mechanism approach the winding mold respectively, driving the two side pressure blocks 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. The clamp head then clamps the two sides of the wire end clamp, further clamping the wire end clamp to the two sides of the wire end, thus ensuring that the wire take-up clamp and the coil, and the wire end clamp and the wire end are in full contact. Then, the two side pressure seats move away from the winding mold respectively, and the clamp head also opens the clamping space. The wire take-up clamp and the wire end clamp together bring the coil out of the winding mold through adhesive force. In this way, the winding mold can automatically wind the wire and automatically twist it on the coil to form a wire end, reducing manual intervention and greatly improving winding efficiency and quality.

[0006] As a further improvement to the above technical solution, the lead frame is provided with a lead wheel, a wire pressing drive and a fixing block. The lead wheel is located above the fixing block, and the wire pressing drive is connected to the wire pressing block. The wire pressing drive can drive the wire pressing block to move closer to or away from the fixing block.

The push-pull drive is connected to the transmission rod, which passes through the transmission sleeve and connects to the wedge rod. The wedge rod is located between the upper die and the lower die. The top and bottom surfaces of the wedge rod are inclined towards each other in a direction away from the transmission rod. An upper elastic element is provided between the rotating base and the upper die, which presses the upper die against the top surface of the wedge rod. A lower elastic element is provided between the rotating base and the lower die, which presses the lower die against the bottom surface of the wedge rod.

[0009] As a further improvement to the above technical solution, the hooking mechanism includes a forward and backward translation drive, a hooking horizontal movement drive, a hooking lifting drive, and a second motor.

The hooking lifting drive is mounted on the hooking horizontal movement drive and can drive the hooking lifting drive to move left and right. The second motor is mounted on the hooking lifting drive and can drive the hooking lifting drive to move up and down. The second motor is connected to the hook needle and can drive the hook needle to rotate around an axis in the up and down direction.

[0010] As a further improvement to the above technical solution, the lead wire mechanism includes a lead wire lateral movement drive and a lead wire lifting drive. The lead wire lateral movement drive is disposed on the front-to-back translation drive, and the front-to-back translation drive can drive the lead wire lateral movement drive to move back and forth. The lead wire lifting drive is disposed on the lead wire lateral movement drive, and the lead wire lateral movement drive can drive the lead wire lifting drive to move left and right. The lead wire frame is disposed on the lead wire lifting drive, and the lead wire lifting drive can drive the lead wire frame to move up and down.

[0011] As a further improvement to the above technical solution, the forward and backward translation drive includes a first sliding group, a translation drive source, and a second sliding group. The translation drive source is connected to a first pressure block and a second pressure block. The translation drive source can drive the first pressure block and the second pressure block to move back and forth.

[0026] Reference Figure 1 A winding device includes a winding mechanism, a lead-in mechanism, a hook-in mechanism, and a side-pressing mechanism. The winding mechanism has a rotating base 110 rotatable about a horizontal axis, on which a wire clamping portion 120 and a winding mold 130 are provided. The wire clamping portion 120 has an openable and closable wire clamping space. The lead-in mechanism has a lead-in frame 141 movable between the wire clamping portion 120 and the winding mold 130, with a lead-in nozzle 142 on its bottom side. The hook-in mechanism has a hook 151 movable between the lead-in nozzle 142 and the winding mold 130. The side-pressing mechanism has side-pressing seats located on the left and right sides of the winding mold 130. 161, the two side pressure seats 161 can be close to or away from the winding mold 130 respectively, and the two side pressure seats 161 are respectively connected to the side of the winding mold 130. At least one of the side pressure seats 161 is connected to a wire cutter 163; the upper pressure 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. In practical applications, the chuck 171 includes a clamping drive and a clamping block. The clamping drive can be a pneumatic finger or an electric finger. The clamping drive drives the two clamping blocks to move closer or further away from each other, thereby forming an openable clamping space between the two clamping blocks.

[0027] As described above, 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 within 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. 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 on the winding die 130. This process is repeated to create multiple head shapes on the coil during winding. When the coil is finished winding, the lead tip 142 moves past the wire cutter to cut the wire, and the external wire pick-up clamp comes into contact with the wire head clamp. 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 head clamp is tightened on both sides, and the wire end clamp is further tightened on 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
