Description

[0001] This application is a divisional application. The original application has the application number "202211324616.5" and the application date is "October 27, 2022". The invention title is "High-efficiency winding machine". Technical Field

[0002] This invention relates to the field of winding machines, and particularly to a clamping mechanism and a corresponding winding machine. Background Technology

[0003] Electric motors are a common type of drive device, and with the development of technology, many processes in motor manufacturing are now performed by machines. For example, the operation of winding enameled wire around the stator is now primarily done by winding machines. Currently, there are various types of winding machines on the market, such as double-head stator winding machines and four-head stator winding machines designed to improve efficiency. Furthermore, the ends of the enameled wire need to be stripped after winding, so some winding machines with stripping mechanisms also exist. However, existing winding machines require a considerable downtime for loading and unloading operations after processing, which affects work efficiency.

[0004] Therefore, it is necessary to provide a clamping mechanism and a corresponding winding machine to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a clamping mechanism and a corresponding winding machine to solve the problem of low efficiency caused by the need to stop the winding machine for loading and unloading operations in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a clamping mechanism, which includes a first clamp, a second clamp, a transfer frame, a first rotary drive unit, and a second rotary drive unit;

[0007] The output end of the first rotary drive unit is provided with a connector for sliding connection with the first clamp or the second clamp. The two ends of the connector are a loading end and a unloading end, respectively. The transfer frame is connected to the output end of the second rotary drive unit. The transfer frame is provided with a first sliding member and a second sliding member. The transfer frame rotates to make the first sliding member engage with the loading end or the unloading end of the connector, or to make the second sliding member engage with the loading end or the unloading end of the connector. When the first sliding member engages with the loading end, the second sliding member engages with the unloading end. When the first sliding member engages with the unloading end, the second sliding member engages with the loading end. The first clamp can slide and switch positions between the connector, the first sliding member, and the second sliding member. The second clamp can slide and switch positions between the connector, the first sliding member, and the second sliding member.

[0008] In this invention, both the first clamp and the second clamp include a clamp base and a clamping rod rotatably connected to the outside of the clamp base. The top end of the clamp base is provided with a receiving hole for placing a product. The two ends of the clamping rod are a clamping end and a control end, respectively. A spring is provided between the control end and the clamp base. The spring is used to compress the clamping rod so that the clamping end clamps the product in the receiving hole.

[0009] The clamping mechanism further includes a clamping control component located on the side near the feeding end. The clamping control component includes a first sliding drive part and a pressing rod connected to the output end of the first sliding drive part. The pressing rod rotates the clamping rod by sliding and pressing it, causing the clamping end to release the product.

[0010] The first sliding drive unit is a motor lead screw assembly, the pressing rod is connected to the lead screw of the motor lead screw assembly via a lead screw drive, and the clamping control assembly further includes a guide rod parallel to the lead screw, with the pressing rod slidably connected to the guide rod.

[0011] In addition, the second rotary drive unit is a ring gear that is coaxially rotatably sleeved on the outer periphery of the output end of the first rotary drive unit;

[0012] The clamping control assembly also includes a gear rack connected to the extrusion rod. When the distance between the extrusion rod and the clamping rod is greater than or equal to a set distance, the gear rack is connected to the ring gear. When the distance between the extrusion rod and the clamping rod is less than the set distance, the gear rack is separated from the ring gear.

[0013] Furthermore, a transfer gear is connected between the ring gear and the gear rack for transmission.

[0014] In addition, a clamping rod is symmetrically arranged on each side of the clamping seat. The clamping control component includes a pressing rod corresponding to each of the two clamping rods. The two pressing rods are symmetrically connected to both sides of the gear rack. Either pressing rod on each side presses either clamping rod, and the linkage component causes both clamping rods to release the product.

[0015] Furthermore, a clamping rod is symmetrically arranged on each side of the clamping seat, and the clamping control component includes a pressing rod corresponding to each of the two clamping rods, with the two clamping rods being the first clamping rod and the second clamping rod, respectively.

[0016] The linkage assembly includes a first linkage rod, a second linkage rod, a first transmission rod, and a second transmission rod;

[0017] The first linkage rod is slidably connected to the clamp seat, the first transmission rod is rotatably connected to the clamp seat, one end of the first transmission rod is connected to the first linkage rod, the other end is connected to the control end of the first clamp rod, and the end of the first linkage rod away from the first transmission rod is connected to the control end of the second clamp rod.

[0018] The second linkage rod is slidably connected to the clamp seat, the second transmission rod is rotatably connected to the clamp seat, one end of the second transmission rod is connected to the second linkage rod, the other end is connected to the control end of the second clamp rod, and the end of the second linkage rod away from the second transmission rod is connected to the control end of the first clamp rod.

[0019] The first linkage rod and the second linkage rod are centrally symmetrical about the central axis of the fixture seat, and the first transmission rod and the second transmission rod are centrally symmetrical about the central axis of the fixture seat.

[0020] Furthermore, the first linkage rod is provided with a receiving groove, and a fixed column is provided in the receiving groove. The first transmission rod is movably connected to the fixed column through a long strip groove.

[0021] In this invention, a limiting member for restricting the rotation of the ring gear is movably disposed on the base. The limiting member has a triangular structure, with a positioning part at one end and triggering parts at the other two ends. The ring gear has positioning holes corresponding to the positioning parts. The two triggering parts are respectively located on both sides of the radial line of the ring gear perpendicular to the gear rack. Both triggering parts are located on the movement trajectory of the gear rack. Before the gear rack meshes with the ring gear, it squeezes the triggering parts, causing the positioning part to disengage from the restriction on the ring gear.

[0022] The clamping mechanism further includes a loading / unloading drive assembly, which includes a second sliding drive unit, a sliding seat, a third rotary drive unit, and a push rod. The sliding seat is slidably disposed on the base and driven to slide by the second sliding drive unit. The third rotary drive unit is fixedly disposed on the sliding seat. The push rod is rotatably disposed on the sliding seat and connected to the output end of the third rotary drive unit. The rotation axis of the push rod is parallel to the sliding trajectory of the sliding seat. The push rod is provided with a first extension rod for pushing the first clamp to slide and a second extension rod for pushing the second clamp to slide.

[0023] The present invention also includes a winding machine that uses the above-mentioned clamping mechanism, the winding machine further including a base, a winding mechanism, a moving module, a wire cutting and clamping mechanism, and a wire feeding mechanism;

[0024] The movable module, the clamping mechanism, and the wire feeding mechanism are all mounted on the base. The movable module is positioned between the wire feeding mechanism and the clamping mechanism. The winding mechanism is positioned on the side of the movable module closer to the clamping mechanism. The enameled wire fed out by the wire feeding mechanism passes through the winding mechanism. The clamping mechanism holds a product to be wound, and the winding mechanism pulls the enameled wire to be wound onto the product. The wire cutting and clamping mechanism is mounted on the base. The wire cutting and clamping mechanism is used to clamp the wire end, and after winding is completed, the wire cutting and clamping mechanism cuts the enameled wire closest to the product.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the winding machine of the present invention can drive the transfer frame to rotate, so that the first sliding joint and the second sliding joint can be switched to dock at the loading end or unloading end of the connector, thereby allowing the first clamp and the second clamp to cyclically switch positions on the connector, the first sliding joint and the second sliding joint, so that loading and unloading operations can be performed simultaneously with the winding operation, thereby improving work efficiency.

[0041] Existing winding machines require a considerable amount of time to stop for loading and unloading after the product is finished, which affects work efficiency.

[0042] The following is a first embodiment of a winding machine provided by the present invention that can solve the above-mentioned technical problems.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 This is a schematic diagram of the structure of the first embodiment of the winding machine of the present invention. Figure 2 This is a schematic diagram illustrating the operating principle of the first and second clamps in the first embodiment. Figure 3 for Figure 2 View is a schematic diagram of the structure after removing the first and second clamps.

[0044] In the diagram, units with similar structures are represented by the same labels.

[0045] This embodiment provides a winding machine, which includes a base 11, a clamping mechanism 12, a winding mechanism 13, a moving module 14, and a wire feeding mechanism 15. The moving module can refer to the XYZ moving module commonly found in the prior art.

[0046] The movable module 14, clamping mechanism 12, and wire feeding mechanism 15 are all mounted on the base 11. The movable module 14 is positioned between the wire feeding mechanism 15 and the clamping mechanism 12. The winding mechanism 13 is positioned on the side of the movable module 14 closest to the clamping mechanism 12. The enameled wire fed out by the wire feeding mechanism 15 passes through the winding mechanism 13. The product to be wound is mounted on the clamping mechanism 12, and the enameled wire is wound onto the product by the winding mechanism 13. A wire cutting and clamping mechanism 18 is also provided on the base 11. The wire cutting and clamping mechanism 18 can clamp the wire end, allowing the winding mechanism 13 to move and pull the enameled wire for winding. After winding is completed, the wire cutting and clamping mechanism 18 cuts the enameled wire closest to the product.

[0047] It is understood that the winding mechanism 13, the moving module 14, and the wire feeding mechanism 15 can all adopt the structures in the prior art, which will not be described in detail in this embodiment.

[0048] The winding machine in this embodiment can also be equipped with a varnish stripping mechanism 16. Various varnish stripping mechanism assemblies are available on the market. The varnish stripping mechanism 16 can adopt a structure from the prior art, and its structural principle can be found in the varnish stripping mechanism described in patent document CN 203481615U. The varnish stripping mechanism 16 is located on the side of the moving module 14 near the wire feeding mechanism 15. The enameled wire fed out by the wire feeding mechanism 15 passes through the varnish stripping mechanism 16 and is then led onto the winding mechanism 13. The varnish stripping mechanism 16 can strip the insulating varnish from the enameled wire at the tail end of the product, facilitating subsequent electrical connections of the wound product.

[0049] Please refer to Figures 2-4 In this embodiment, the clamping mechanism 12 includes a clamp 121, a transfer frame, a first rotation drive unit, and a second rotation drive unit. In this embodiment, two clamps 121 are provided. For clarity, the two clamps 121 are referred to as the first clamp 121a and the second clamp 121b.

[0050] The first rotary drive unit can be a motor. The output end of the first rotary drive unit is provided with a connector 124 for sliding connection with the first clamp 121a or the second clamp 121b. The two ends of the connector 124 are a loading end and a unloading end, respectively. Figure 3The lower end of connector 124 is the feeding end, and the upper end is the unloading end.

[0051] The transfer frame is connected to the output end of the second rotary drive unit. The transfer frame is provided with a first sliding member 123 and a second sliding member 125. The transfer frame rotates so that the first sliding member 123 is connected to the loading end or unloading end of the connector 124, or the second sliding member 125 is connected to the loading end or unloading end of the connector 124. When the first sliding member 123 is connected to the loading end, the second sliding member 125 is connected to the unloading end. When the first sliding member 123 is connected to the unloading end, the second sliding member 125 is connected to the loading end.

[0052] like Figure 3 When the connector 124, the first sliding member 123, and the second sliding member 125 are aligned in a straight line, the first clamp 121a can slide and switch positions among the connector 124, the first sliding member 123, and the second sliding member 125, and the second clamp 121b can slide and switch positions among the connector 124, the first sliding member 123, and the second sliding member 125. It is also understood that elastic telescopic positioning posts for positioning the clamp 121 can be provided on the connector 124, the first sliding member 123, and the second sliding member 125. These elastic telescopic positioning posts can be referenced from... Figure 3 The reference number 1231.

[0053] Please refer to Figure 2 In this embodiment, the clamping mechanism 12 further includes a loading / unloading drive assembly, which includes a second sliding drive unit 25, a sliding seat 22, a third rotary drive unit 23, and a push rod 24. The sliding seat 22 is slidably mounted on the base 11 and is driven to slide by the second sliding drive unit 25. The third rotary drive unit 23 is fixedly mounted on the sliding seat 22. The push rod 24 is rotatably mounted on the sliding seat 22 and connected to the output end of the third rotary drive unit 23. The rotation axis of the push rod 24 is parallel to the sliding trajectory of the sliding seat 22. The push rod 24 is provided with a first extension rod 211 for pushing the first clamp 121a to slide and a second extension rod 212 for pushing the second clamp 121b to slide. The third rotary drive unit 23 drives the push rod 24 to rotate, which allows the first extension rod 211 to avoid being positioned relative to the first clamp 121a and the second extension rod 212 to avoid being positioned relative to the second clamp 121b, so that the first extension rod 211 and the second extension rod 212 can drive the clamp 121 in the next round.

[0054] like Figure 2In this configuration, the first clamp 121a is connected to the connector 124. After the product on the first clamp 121a is wound, the first clamp 121a is pushed onto the first sliding member 123, and the second clamp 121b, carrying the unwound product, is pushed onto the connector 124. Furthermore, when the product on the second clamp 121b is being wound, the transfer frame rotates, causing the first sliding member 123 and the second sliding member 125 to switch positions. Simultaneously, the wound product is moved to the side closest to the operator, who can then perform sorting, unloading, and reloading operations. The unloading and winding operations do not interfere with each other, resulting in high efficiency.

[0055] Please refer to Figure 4 In this embodiment, both the first clamp 121a and the second clamp 121b include a clamp base 1211 and a clamping rod rotatably connected to the outside of the clamp base 1211. The top end of the clamp base 1211 is provided with a receiving hole for placing the product, and the two ends of the clamping rod are a clamping end and a control end (e.g., ...) Figure 4 In the middle, the top end of the clamping rod is the clamping end and the bottom end is the control end. A spring 1214 is provided between the control end and the clamping seat 1211. The spring 1214 is used to squeeze the clamping rod so that the clamping end clamps the product in the receiving hole.

[0056] The clamping mechanism 12 also includes a clamping control component 122, located near the loading end. The clamping control component 122 includes a first sliding drive unit and a pressing rod 1222 connected to the output end of the first sliding drive unit. The pressing rod 1222 rotates via a sliding pressing clamp, causing the clamping end to release the product. It should be noted that in this embodiment, the first sliding drive unit is a motor screw assembly. The pressing rod 1222 is driven by the screw 1221 and is equipped with a guide rod 1224 parallel to the screw 1221. The pressing rod 1222 and the guide rod 1224 are slidably connected. Of course, the first sliding drive unit can also be other linear drive mechanisms from the prior art.

[0057] The second rotary drive unit is a ring gear 126 coaxially rotatably sleeved on the outer periphery of the output end of the first rotary drive unit. It can be understood that the second rotary drive unit could also be a structure such as a motor that directly drives the transfer frame, but in this embodiment, the transfer frame is directly made into a gear structure and connected to the moving part of the clamping control component 122 for transmission, which saves costs and is convenient to control.

[0058] Please refer to Figures 4-7Specifically, the clamping control assembly 122 also includes a rack 1223, which is connected to the pressing rod 1222. When the distance between the pressing rod 1222 and the clamping rod is greater than or equal to a set distance, the rack 1223 is connected to the ring gear 126. When the distance between the pressing rod 1222 and the clamping rod is less than the set distance, the rack 1223 is separated from the ring gear 126. That is, during the sliding process of the pressing rod 1222, it first drives the rack 1223 to slide, and then drives the ring gear 126 to rotate, thereby causing the first sliding member 123 and the second sliding member 125 to switch positions, transferring the wound product to the side closer to the operator. Only then will the pressing rod 1222 slide to control the clamping of the wound product.

[0059] It is understandable that an intermediate gear 1261 can be set between the ring gear 126 and the gear rack 1223 to facilitate the design of the transmission ratio.

[0060] In this embodiment, a clamping rod is symmetrically arranged on both sides of the clamping base 1211. The clamping control component 122 includes a pressing rod 1222 that corresponds one-to-one with the two clamping rods. For clarity, the two clamping rods are referred to as the first clamping rod 1212 and the second clamping rod 1213.

[0061] Please refer to Figure 4 and Figure 5 The clamping control assembly 122 also includes a first linkage rod 1216, a second linkage rod 1217, a first transmission rod 1215, and a second transmission rod 1218.

[0062] The first linkage rod 1216 is slidably connected to the clamp seat 1211, and the first transmission rod 1215 is rotatably connected to the clamp seat 1211. One end of the first transmission rod 1215 is connected to the first linkage rod 1216, and the other end is connected to the control end of the first clamping rod 1212. The end of the first linkage rod 1216 away from the first transmission rod 1215 is connected to the control end of the second clamping rod 1213. Please refer to... Figure 7 It is understood that the first linkage rod 1216 is provided with a receiving groove 12161, and a fixed post 12162 is provided in the receiving groove 12161. The first transmission rod 1215 is movably connected to the fixed post 12162 through a long strip groove, so as to adapt to the cooperation between various components during the rotation of the first transmission rod 1215.

[0063] The second linkage rod 1217 is slidably connected to the clamp seat 1211, the second transmission rod 1218 is rotatably connected to the clamp seat 1211, one end of the second transmission rod 1218 is connected to the second linkage rod 1217, and the other end is connected to the control end of the second clamping rod 1213. The end of the second linkage rod 1217 away from the second transmission rod 1218 is connected to the control end of the first clamping rod 1212.

[0064] The first linkage 1216 and the second linkage 1217 are centrally symmetrical about the central axis of the clamp seat 1211, and the first transmission rod 1215 and the second transmission rod 1218 are centrally symmetrical about the central axis of the clamp seat 1211.

[0065] Furthermore, a pressing rod 1222 is symmetrically connected to each side of the gear rack 1223. Either pressing rod 1222 on either side can press either clamping rod, causing the two clamping rods to release the product. In this way, the gear rack 1223 can control the release of the product from the clamping rods in two batches with one back-and-forth sliding motion.

[0066] Please refer to Figure 6 and Figure 8 Furthermore, a limiting member 127 for restricting the rotation of the ring gear 126 is movably disposed on the base 11. The limiting member 127 has a triangular structure. The limiting member 127 is elastically slidably embedded in the base 11 in conjunction with a spring. One end of the limiting member 127 is provided with a positioning part 1271, and the other two ends are provided with trigger parts 1272. Under the action of the elastic force of the spring, both the positioning part 1271 and the trigger part 1272 protrude from the surface of the base 11.

[0067] The ring gear 126 is provided with positioning holes corresponding to the positioning part 1271. Two trigger parts 1272 are located on either side of the radial line of the ring gear 126 perpendicular to the rack 1223. Both trigger parts 1272 are located on the movement trajectory of the rack 1223. Before the rack 1223 meshes with the ring gear 126, the rack 1223 can squeeze the trigger parts 1272, causing the positioning part 1271 to retract and disengage from the ring gear 126. Then, the rack 1223 can drive the ring gear 126 to rotate. For example... Figure 6 When the gear rack 1223 slides close to the ring gear 126 from different sides, it will squeeze different trigger parts 1272.

[0068] The loading and unloading working principle of the winding machine in this embodiment is as follows: Please refer to... Figure 2 First, the clamping control component 122 drives the clamping rod to open. Then, a product that needs to be wound can be placed on the second clamp 121b. Then, the second sliding drive unit 2 and the third rotary drive unit 23 cooperate to control the first extension rod 211 to push the first clamp 121a to slide onto the first sliding member 123, and control the second extension rod 212 to push the second clamp 121b to slide onto the connector 124. In this way, the first rotary drive unit can drive the second clamp 121b to rotate, and cooperate with the winding mechanism 13 to wind the wire.

[0069] Simultaneously, the first sliding drive unit drives the pressing rod 1222 to slide, which in turn drives the gear rack 1223 to slide, and then drives the ring gear 126 to rotate. This causes the first sliding member 123 and the second sliding member 125 to switch positions, moving the first clamp 121a to the side closer to the operator. Then, the pressing rod 1222 continues to slide, pressing the clamping rod on the first clamp 121a, causing the clamping end to loosen. If there are finished products on the first clamp 121a at this time, the products are removed and tidied up. Then, the next product that needs to be wound is placed on the first clamp 121a. Subsequently, the clamping control component 122 pushes the product that needs to be wound into the loading position, and the clamping control component 122, in conjunction with the transfer frame, pushes the finished product out of the loading position, thus forming a work cycle.

[0070] This completes the loading and unloading process of the winding machine in this embodiment.

[0071] The following is a second embodiment of a winding machine provided by the present invention that can solve the above-mentioned technical problems. The main difference between this embodiment and the first embodiment lies in the different driving structure of the clamping control component for the clamping rods. In the first embodiment, a single pressing rod controls the movement of two clamping rods through a transmission rod and a linkage rod, with a gear rack sliding back and forth, and the pressing rods on both sides controlling the clamping rods to release the product once each. In this embodiment, two pressing rods correspondingly control the movement of two clamping rods, with a gear rack sliding back and forth, and the two pressing rods controlling the clamping rods to release the product only once. This embodiment eliminates the need for transmission rods, linkage rods, and other such structures.

[0072] In this embodiment, the same or unchanged structures as in the first embodiment are represented by the same reference numerals.

[0073] This embodiment provides a winding machine, which includes a base 11, a clamping mechanism 12, a winding mechanism 13, a moving module 14, and a wire feeding mechanism 15.

[0074] The movable module 14, clamping mechanism 12, and wire feeding mechanism 15 are all mounted on the base 11. The movable module 14 is positioned between the wire feeding mechanism 15 and the clamping mechanism 12. The winding mechanism 13 is positioned on the side of the movable module 14 closest to the clamping mechanism 12. The enameled wire fed out by the wire feeding mechanism 15 passes through the winding mechanism 13. The product to be wound is mounted on the clamping mechanism 12, and the enameled wire is wound onto the product by the winding mechanism 13. A wire cutting and clamping mechanism 18 is also provided on the base 11. The wire cutting and clamping mechanism 18 can clamp the wire end, allowing the winding mechanism 13 to move and pull the enameled wire for winding. After winding is completed, the wire cutting and clamping mechanism 18 cuts the enameled wire closest to the product.

[0075] It is understood that the winding mechanism 13, the moving module 14, and the wire feeding mechanism 15 can all adopt the structures in the prior art, which will not be described in detail in this embodiment.

[0076] Please refer to Figures 2-4 In this embodiment, the clamping mechanism 12 includes a clamp 121, a transfer frame, a first rotation drive unit, and a second rotation drive unit. In this embodiment, two clamps 121 are provided. For clarity, the two clamps 121 are referred to as the first clamp 121a and the second clamp 121b.

[0077] The output end of the first rotary drive unit is provided with a connector 124 for sliding connection with the first clamp 121a or the second clamp 121b. The two ends of the connector 124 are the loading end and the unloading end, respectively. The transfer frame is connected to the output end of the second rotary drive unit. The transfer frame is provided with a first sliding member 123 and a second sliding member 125. The transfer frame rotates so that the first sliding member 123 abuts against the loading end or the unloading end of the connector 124, or so that the second sliding member 125 abuts against the loading end or the unloading end of the connector 124. When the first sliding member 123 abuts against the loading end, the second sliding member 125 abuts against the unloading end, and when the first sliding member 123 abuts against the unloading end, the second sliding member 125 abuts against the loading end.

[0078] like Figure 3 When the connector 124, the first sliding member 123, and the second sliding member 125 are aligned in a straight line, the first clamp 121a can slide and switch positions among the connector 124, the first sliding member 123, and the second sliding member 125, and the second clamp 121b can slide and switch positions among the connector 124, the first sliding member 123, and the second sliding member 125.

[0079] Please refer to Figure 2 In this embodiment, the clamping mechanism 12 further includes a loading / unloading drive assembly, which includes a second sliding drive unit 25, a sliding seat 22, a third rotary drive unit 23, and a push rod 24. The sliding seat 22 is slidably mounted on the base 11 and is driven to slide by the second sliding drive unit 25. The third rotary drive unit 23 is fixedly mounted on the sliding seat 22. The push rod 24 is rotatably mounted on the sliding seat 22 and connected to the output end of the third rotary drive unit 23. The rotation axis of the push rod 24 is parallel to the sliding trajectory of the sliding seat 22. The push rod 24 is provided with a first extension rod 211 for pushing the first clamp 121a to slide and a second extension rod 212 for pushing the second clamp 121b to slide. The third rotary drive unit 23 drives the push rod 24 to rotate, which allows the first extension rod 211 to avoid being positioned relative to the first clamp 121a and the second extension rod 212 to avoid being positioned relative to the second clamp 121b, so that the first extension rod 211 and the second extension rod 212 can drive the clamp 121 in the next round.

[0080] like Figure 2In this configuration, the first clamp 121a is connected to the connector 124. After the product on the first clamp 121a is wound, the first clamp 121a is pushed onto the first sliding member 123, and the second clamp 121b, carrying the unwound product, is pushed onto the connector 124. Furthermore, when the product on the second clamp 121b is wound, the transfer frame rotates, causing the first sliding member 123 and the second sliding member 125 to switch positions. Simultaneously, the wound product is transferred to the side closest to the operator, who can then perform sorting, unloading, and reloading operations. The unloading and winding operations do not interfere with each other, resulting in high efficiency.

[0081] Please refer to Figure 4 In this embodiment, both the first clamp 121a and the second clamp 121b include a clamp base 1211 and a clamping rod rotatably connected to the outside of the clamp base 1211. The top end of the clamp base 1211 is provided with a receiving hole for placing the product. The two ends of the clamping rod are a clamping end and a control end, respectively. A spring 1214 is provided between the control end and the clamp base 1211. The spring 1214 is used to squeeze the clamping rod so that the clamping end clamps the product in the receiving hole.

[0082] The clamping mechanism 12 also includes a clamping control component 122, which is located on the side near the feeding end. The clamping control component 122 includes a first sliding drive part and a pressing rod 33 connected to the output end of the first sliding drive part. The pressing rod 33 rotates by sliding the pressing clamp rod, causing the clamping end to release the product.

[0083] The second rotary drive unit is a ring gear 126 that is coaxially rotated and sleeved on the outer periphery of the output end of the first rotary drive unit.

[0084] Please refer to Figure 9 and Figure 10 The clamping control assembly 122 also includes a connecting rod 35 and a gear rack 1223. The connecting rod 35 is fixedly connected to one of the pressing rods 33, and the gear rack 1223 is slidably connected to the end of the connecting rod 35 away from the pressing rod 33 (the sliding direction is...). Figure 9 (Vertical direction of view) A guide groove 34 is provided on the base 11. The guide groove 34 includes a first guide section 341, a second guide section 342, a first bending section 345 and a second bending section 346. The first bending section 345 and the second bending section 346 are located at the two ends of the first guide section 341, and the first bending section 345 connects the first guide section 341 and the second guide section 342, and the second bending section 346 connects the first guide section 341 and the second guide section 342.

[0085] The gear rack 1223 is provided with a guide post 361 that is slidably connected to the guide groove 34. When the guide post 361 slides within the first guide section 341, the gear rack 1223 is connected to the ring gear 126 in a transmission manner. When the pressing rod 33 slides close to the clamp 121, the guide post 361 slides within the first guide section 341.

[0086] When the guide post 361 slides within the second guide section 342, the gear rack 1223 and the ring gear 126 are separated by a set distance. As the pressing rod 33 slides away from the clamp 121, the guide post 361 slides within the second guide section 342.

[0087] A first one-way limiting rod 343 is provided for elastic rotation between the first bending section 345 and the first guide section 341, such as Figure 10 The first one-way limiting rod 343 revolves around the first rotating shaft 3431. It can be understood that a torsion spring can be connected between the first rotating shaft 3431 and the base 11 so that the first one-way limiting rod 343 is held in place. Figure 10 The diagram shows the state where the first bent section 345 and the first guide section 341 are separated. The first one-way limiting rod 343 has a curved structure and is used to one-way limit the guide post 361 from sliding from the first bent section 345 to the first guide section 341.

[0088] A second one-way limiting rod 344 is provided for elastic rotation between the second bending section 346 and the second guide section 342, such as Figure 10 The first one-way limiting rod 343 revolves around the second rotating shaft 3441. The second one-way limiting rod 344 has a curved structure and is used to one-way limit the guide post 361 from sliding from the second bent section 346 to the second guide section 342.

[0089] It is understandable that, such as Figure 10 The first bending section 345 extends to the right with an extension section. After the gear rack 1223 is disengaged from the ring gear 126, the extrusion rod 33 continues to slide to extrude the clamping rod. During this process, the guide post 361 slides within the extension section.

[0090] The clamping base 1211 has a clamping rod symmetrically arranged on each side. The clamping control assembly 122 includes a pressing rod 33 corresponding to the clamping rods on both sides of the clamping base 1211. The two pressing rods 33 simultaneously press the two clamping rods to release the product. Figure 9 The two extrusion rods 33 slide close to each other to extrude pressure on the clamping rods on both sides of the clamping seat 1211, or the two extrusion rods 33 slide away from each other, resulting in very stable control of the clamping rods.

[0091] In this embodiment, the clamping control assembly 122 includes a first drive rod 31 and a second drive rod 32. The first drive rod 31 is provided with a first transmission section and a first optical axis section, and the second drive rod 32 is provided with a second transmission section and a second optical axis section. Figure 9 The transmission section and the optical axis section are simply divided into a dotted area and an undotted area. One extrusion rod 33 is connected to the first transmission section and is slidably connected to the second optical axis section to form a sliding guide. The other extrusion rod 33 is connected to the second transmission section and is slidably connected to the first optical axis section to form a sliding guide. This makes the sliding very stable.

[0092] The working principle of this embodiment is largely the same as that of the first embodiment, combined with... Figure 2 and Figure 9 The difference lies in the following: When the first sliding drive unit drives the pressing rod 33 to slide, it first drives the gear rack 36 to slide. At this time, the guide post 361 on the gear rack 36 slides within the first guide section 341. The gear rack 1223 and the ring gear 126 can mesh, and then the ring gear 126 can be driven to rotate. This causes the first sliding member 123 and the second sliding member 125 to switch positions, moving the first clamp 121a to the side closer to the operator. Then, the pressing rod 33 continues to slide, and the gear rack 1223 and the ring gear 126 will disengage. The pressing rod 33 will press the clamping rod on the first clamp 121a, causing the clamping end to loosen. If there is a finished product on the first clamp 121a at this time, the product is removed and tidied up. Then, the next product that needs to be wound can be placed on the first clamp 121a.

[0093] After the new product requiring winding is placed, the first sliding drive unit drives the pressing rod 33 to slide away from the first clamp 121a. Due to the restriction of the first one-way limiting rod 343, the guide post 361 slides towards the second guide section 342 for reset. Therefore, during the reset process, the gear rack will not form a transmission engagement with the ring gear 126. Then, under the restriction of the second one-way limiting rod 344, the guide post 361 enters the first guide section 341, thus forming a working cycle.

[0094] The winding machine of this invention can drive the transfer frame to rotate, allowing the first and second sliding joints to switch between the loading and unloading ends of the connector. This enables the first and second clamps to cyclically switch positions on the connector, the first sliding joint, and the second sliding joint. When one clamp is connected to the connector, the winding operation can be performed. The rotation of the transfer frame rotates and outputs the wound product from the first or second sliding joint. Then, the operator can perform loading and unloading and product assembly operations. The winding operation can be performed simultaneously with the loading and unloading operation, resulting in high work efficiency. The advantages of this equipment are even more obvious when there are multiple processing stations.

[0095] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
