Disclosed are two synchronous winding paths formed after winding a wire, and a specific winding structure for realizing such winding paths. This allows the wire conveying structure that needs to convey products on both sides at the same time to avoid the need to set up two wires separately. The method of realizing two synchronous paths through a wire not only reduces the production cost of the equipment, but also reduces the synchronous restriction structure of the two lines during the movement because the driving of a wire causes the two paths to move simultaneously, thereby improving the accuracy of wire conveying.

[0025] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0026] For some special products, reels are used for winding before and after processing, such as lithium battery pole pieces. When such products are processed in detail, wires are often needed for threading. When threading lithium battery pole pieces, steel wires are used as wires for threading, forming a line pulled by wire 7 to drive the product. When driving the wire 7 to thread, a threading rod is also set on the wire 7 to fix the product. In order to ensure the stability of the threading rod running on the wire 7, a wire 7 path is generally set at each end of the threading rod, and the threading rod is driven synchronously by two wires 7 to thread.

[0027] Reference Figure 1 The present application discloses a method for threading a single wire 7, comprising a first threading path 1 and a second threading path 2, wherein the first threading path 1 and the second threading path 2 are connected and move synchronously, and a first starting position 11 and a first ending position 12 are provided on the first threading path 1, and the second threading path 2 comprises a second starting position 21 and a second ending position 22, and the starting position and the ending position of the two threading paths are both correspondingly provided in the Y-axis direction. For the convenience of description, the movement direction of the threading path is set to the Y-axis direction, so the bottom of the support member is taken as the base, and the direction in which the support member extends upward is the Z-axis direction. The two end supports on the support member need to be connected, and the winding structure is provided on the end supports, so the direction in which the end supports are connected is set to the X-axis direction. The first threading path 1 is formed between the first starting position 11 and the first ending position 12, and the second threading path 2 is formed between the second starting position 21 and the second ending position 22. The lengths of the first threading path 1 and the second threading path 2 are the same, and the first threading path 1 and the second threading path 2 are provided in parallel on the plane formed by the X-axis and the Y-axis. The two threading paths are interconnected, realizing the process of forming two threading paths by winding a wire 7 in different directions. The two threading paths are interconnected. When one of the threading paths moves, the other will also move synchronously, and the synchronization process is precise, which improves the accuracy of the threading process.

[0028] See also Figure 2 To realize the interconnection between two parallel belt-threading paths, a single wire 7 belt-threading structure is also required, including a head-end belt-threading assembly 8, a tail-end belt-threading assembly 9 and a wire 7, wherein the wire 7 includes a head end and a tail end, and the wire 7 sequentially bypasses the head-end belt-threading assembly 8 and the tail-end belt-threading assembly 9, wherein the head end and the tail end of the wire 7 are connected at the beginning of the head-end belt-threading assembly 8 to form a circular belt-threading path, and the wire 7 connected at the head end and the tail end forms two parallel paths between the head-end belt-threading assembly 8 and the tail-end belt-threading assembly 9, and the two paths are synchronously moved by the driving of the head-end belt-threading assembly 8 and the tail-end belt-threading assembly 9, and the head-end belt-threading assembly 8 and the tail-end belt-threading assembly 9 are correspondingly arranged. In addition, two groups of wire 7 outlets are arranged at both ends of the head-end belt-threading assembly 8 and the tail-end belt-threading assembly 9, and the wire 7 is connected and connected at the two groups of wire 7 outlets of the head-end belt-threading assembly 8 and the two groups of outlets of the tail-end belt-threading assembly 9, thus forming two mutually parallel belt-threading paths. In addition, a winding structure is provided between the two outlets of the head-end threading component 8 and the tail-end threading component 9. After the wire 7 is wound in different directions by the winding structure, a wire 7 is formed to complete two threading paths on the head-end threading component 8 and the tail-end threading component 9.

[0029] A variety of turning paths are also provided between the two belt-threading paths formed by the serial connection of a wire 7, so that the first belt-threading path 1 and the second belt-threading path 2 can run in parallel and synchronously. The various turning paths correspond to the winding structures on the head-end belt-threading assembly 8 and the tail-end belt-threading assembly 9, and different winding structures can form a variety of turning paths. The second turning path is formed between the first starting position 11 and the second ending position 22, and the first turning path is formed between the first ending position 12 and the second starting position 21. The first turning path and the second turning path form the connection between the first belt-threading path 1 and the second belt-threading path 2. Only the turning path can change the movement direction of the wire 7 at this position, so that a wire 7 can turn from one movement direction to another, and the starting point and end point of the two belt-threading paths are the same, and the movement process is synchronized, which greatly increases the running accuracy of the belt-threading path, and the transmission structure formed by the winding of a wire also greatly simplifies the structural form of synchronously driving two wires 7 at the same time, saving costs.

[0030] As the first implementation of the present application, the first turning path includes a first connection path 13 and a first buffer path 14. The first connection path 13 and the first belt-threading path 1 are arranged in parallel on the plane formed by the Y axis and the Z axis. The first buffer path 14 is located at both ends of the first connection path 13, and the first connection path 13 is connected to the first end position 12 and the second start position 21 through the first buffer path 14. The wire 7 has formed the first belt-threading path 1 when it passes through the first start position 11 and reaches the first end position 12. In order to enable the same wire 7 to continue to form the second belt-threading path 2 parallel to the first belt-threading path 1, the end of the first belt-threading path 1 and the beginning of the second belt-threading path 2 are connected, so that the connection between the first belt-threading path 1 and the second belt-threading path 2 is formed. The specific connection process is as follows: the first buffer path 14 includes a first tail end buffer path and a second head end buffer path, the first tail end buffer path is a Z-axis path set at the first end position 12 and the end of the first connection path 13; the second head end path includes a Z-axis buffer path set at the second start position 21 and an X-axis buffer path connecting the Z-axis buffer path and the end of the first connection path 13. The buffer path set along the Z axis at the first end position 12 and the end of the first connection path 13 ensures that the first connection path 13 is set at the bottom of the first tape threading path 1, and the turning buffer path set along the X axis and the Z axis at the other end of the first connection path 13 ensures that the first connection path 13 is not only set at the bottom of the first tape threading path 1 but also that the first tape threading path 1 is located on the same plane. This layout makes the structure of the overall tape threading path clearer, easier to set the corresponding winding structure, and simple overall, and the wires 7 do not interfere with each other, and the running speed is easier to control.

[0031] For the second strapping path 2, the second wearing process has been completed from the second starting position 21 to the second ending position 22. In order to enable the first strapping path 1 and the second wearing path to circulate, the tail of the second strapping path 2 is connected to the starting position of the first strapping path 1. Its connection method is similar to the connection method between the ending position of the first strapping path 1 and the starting position of the second strapping path 2, specifically: the second turning path includes a second connection path 23 and a second buffer path 24, the second connection path 23 and the first connection path 13 are arranged in parallel on the plane formed by the Y axis and the X axis, the second buffer path 24 is located at both ends of the second connection path 23, and the second connection path 23 is connected to the second ending position 22 and the first starting position 11 through the second buffer path 24. The second buffer path 24 includes a second tail end buffer path and a first head end buffer path, the second tail end buffer path includes a Z-axis buffer path set at the second end position 22 and an X-axis buffer path connecting the Z-axis buffer path and the second connection path 23; the first head end path includes a Z-axis buffer path set at the second start position 21 and an X-axis buffer path connecting the Z-axis buffer path and the end of the second connection path. The buffer path set along the Z axis at the second end position 22 and the end of the second connection path 23 ensures that the second connection path 23 is set at the bottom of the second threading path 2, and in order to ensure that the second connection path 23 does not overlap with the first connection path 13, a buffer path extending downward in the Z axis is set at the first start position 11 and the second end position 22, and a connection path in the X-axis direction connected to the end of the second connection path 23 is set between the two Z-axis buffer paths and the second connection path 23, so that the second connection path 23 and the first connection path 13 are ensured to be located in the same plane, and the two connection paths do not interfere with each other. In addition, for paths that intersect during the turning process, an arc-shaped buffer position can be set at the intersection so that the two paths do not interfere with each other, or the auxiliary path length of one of the paths can be directly adjusted so that the two paths are staggered and do not interfere with each other.

[0032] Reference Figure 3 , Figure 4, corresponding to the above-mentioned turning path structure in which a wire 7 is passed through two directions to form different threading paths, a wire threading mechanism is designed, including a driving structure 6 and a winding structure, the driving structure 6 is used to drive the winding structure, the winding structure includes an active component 3, a winding component 4 and a driven component 5, the active component 3 is connected to the driving structure 6, and is driven to rotate by the driving structure 6; in addition, a support is provided, the support includes two end supports arranged in the Z-axis direction and a connecting support connecting the two end supports, the winding structure is arranged on the two end supports, and the driving structure 6 is arranged on the connecting support. Since the support is installed on a certain structure, the driving structure 6 and the winding structure are both arranged on the support, so the bottom of the support is used as the base, the direction in which the support extends upward is the Z-axis direction, the two end supports on the support need to be connected, and the winding structure is arranged on the two end supports, so the direction in which the two end supports are connected is set to the X-axis direction, and the direction perpendicular to the X-axis direction and the Z-axis direction is the Y-axis direction.

[0033] In addition, in order to be able to pass through two synchronous paths, an auxiliary connecting wheel 44 is also provided on the winding assembly 4. The auxiliary connecting wheel 44 is located on any group of the winding assemblies 4 of the head end threading assembly 8 and the tail end threading assembly 9, and the auxiliary connecting wheels 44 on the head end threading assembly 8 and the tail end threading assembly 9 are arranged correspondingly. The two auxiliary winding wheels are used to wrap the wire 7 from the head end conduction assembly to the tail end threading assembly 9.

[0034] The winding assembly 4 is correspondingly provided with two groups, and the rollers in the two symmetrically arranged winding assemblies 4 are also relatively arranged. It is difficult to extend a wire from one group of rollers and directly wind it on the roller on the opposite side, which easily causes the wire to fall off. Therefore, a connecting winding wheel 43 is provided on both groups of winding assemblies 4, and the axis of the connecting winding wheel 43 is arranged in the Z-axis direction. The connecting winding wheel 43 is used for winding the same wire between the two groups of winding assemblies 4. The axles of the ordinary driving wheel 31 and other guide wheels are arranged in the X-axis direction, which causes the side of the roller to rotate in the Z-axis and Y-axis directions. If the axle of the connecting winding wheel 43 is arranged in the Z-axis direction, the roller of the connecting winding wheel 43 will rotate in the X-axis and Y-axis directions. In this way, the wire extending from the driving wheel 31 or other auxiliary wheels can be directly wound on the connecting wire wheel, and then transmitted to other rollers arranged on the opposite side through the two connecting wire wheels, so as to realize the process of two relatively arranged wire driving structures 6 passing a wire through a belt. This avoids the trouble of having two sets of wire driving structures 6 each pass a wire through and then drive them separately, thus saving production costs and improving the operating accuracy of the structure.

[0035] For the active component 3 directly driven by the driven structure 6, it is necessary to connect with the driving structure 6 on the support. The active component 3 includes a driving wheel 31 and a driving shaft 32. The driving shaft 32 is arranged in the X-axis direction. The driving shaft 32 is connected to the driving structure 6. The driving wheel 31 is provided with two groups. The two groups of driving wheels 31 are respectively arranged at the two ends of the driving shaft 32, but not at the end of the driving shaft 32. The end of the driving shaft 32 is installed on the bearing seat, and the driving wheel 31 and the bearing seat are arranged at intervals. The two groups of driving wheels 31 are respectively located in the same plane with the two symmetrically arranged groups of winding components 4, that is, they are located in the same plane with the adjusting guide wheel 41 and the fixed guide wheel 42 on the winding components 4. In this way, the wire bypassed from the driving wheel 31 can be directly wound on the adjusting guide wheel 41 or the fixed guide wheel 42 on the same plane to form a complete winding structure. The driving structure 6 drives the two groups of driving wheels 31 by driving the driving shaft 32. The driving structure 6 can be set as a driving motor. The height of the driving motor arranged on the connecting support is consistent with the height of the active component 3 on the winding structure, or there is a small deviation between the height of the driving motor and the height of the active shaft 32. Then the driving motor is connected to the active shaft 32 of the active component 3 through a gear assembly, so that the driving motor can drive the active shaft 32 to rotate when it rotates, and at the same time drive the active wheel 31 set on the active shaft 32 to rotate.

[0036] In addition, two bearing seats are provided at both ends of the driving shaft 32, and the driving shaft 32 is fixed to the support member through the two bearing seats. The bearing seat is a bearing seat with a tensioning structure, and the bearing seat can be tensioned during use to ensure the stability of the rotation of the driving shaft 32 in the bearing seat.

[0037] The winding assembly 4 also includes an adjusting guide wheel 41 and a fixed guide wheel 42, the axes of which are both arranged in the X-axis direction, and the adjusting guide wheel 41 and the fixed guide wheel 42 are both located above the driving wheel 31, and the adjusting guide wheel 41 and the fixed guide wheel 42 are respectively arranged on both sides above the driving wheel 31. When winding, the two ends of the wire extending from both sides of the driving wheel 31 can be wound around the adjusting guide wheel 41 and the fixed guide wheel 42 respectively, and then wound around the connecting winding wheel 43 and the driven wheel 51 through the buffering of the adjusting guide wheel 41 and the fixed guide wheel 42, so as to complete the winding process of the winding assembly 4 on one side.

[0038] The fixed guide wheel 42 is installed on the support members at both ends through a fixed block and a guide wheel shaft. The guide wheel shaft of the fixed guide wheel 42 is directly fixed on the fixed mounting block. The fixed mounting block is fixed on the support members at both ends through bolts, and an adjustable bolt groove is also provided on the fixed mounting block. The fixed mounting block can be adjustably set on the support members at both ends through the adjustable bolt groove.

[0039] As for the adjusting guide wheel 41, the adjusting guide wheel 41 is arranged on the support member through the adjusting structure, and the adjusting structure adjusts the adjusting guide wheel 41 in the Z-axis direction. The adjusting structure includes an adjusting cylinder and a pressure regulating valve, and the pressure regulating valve is connected to the cylinder shaft of the adjusting cylinder. The pressure regulating valve is used to control the cylinder. The side of the pressure regulating valve is also provided with an adjusting track, and the two sides of the pressure regulating valve cooperate with the adjusting track, and the pressure regulating valve slides and adjusts on the adjusting track. The pressure regulating valve controls the adjusting cylinder and drives the adjusting guide wheel 41 through the adjusting zone port, so that the adjusting guide wheel 41 arranged on the adjusting structure can be adjusted according to the length of the wire, and at the same time, the loose wire can be tensioned to ensure that the wire is in a stable state during operation.

[0040] The driven assembly 5 is arranged above the winding assembly 4. The driven wheel 51 arranged above the winding assembly 4 is the winding position of the wire. The wire can extend from the driven wheel 51 and extend to the next workstation. In order to ensure that the driven wheels 51 on the two end support frames rotate synchronously, the two driven wheels 51 are connected by a connecting shaft. The driven assembly 5 includes a driven wheel 51 and a driven shaft 52. The driven wheel 51 is provided with two groups. The two groups of driven wheels 51 are respectively located at the two ends of the driven shaft 52. The driven wheel 51 is a rotating wheel whose axis is arranged in the X-axis direction and is located in the same plane as the driving wheel 31. Two seat bearings are also provided at both ends of the driven shaft 52, and the driven shaft 52 is fixed to the support member through the two seat bearings. The installation method of the driven wheel 51 and the driven shaft 52 is similar to that of the driving wheel 31 and the driving shaft 32. Both are arranged on the two end supports through seat bearings, and the driving shaft 32 and the connecting support are arranged at the bottom of the two end supports, and the driven shaft 52 is arranged at the top of the two end supports. In order to ensure the stability of the vertically arranged two end supports, a connecting shaft is also arranged on the top of the two end supports, and the two ends of the connecting shaft are directly fixed on the two end supports on both sides, thereby increasing the stability of the upper ends of the two end supports.

[0041] For the present belt threading mechanism, the two driven wheels 51 of the head-end belt threading assembly 8 are the starting positions of the belt threading path, and the two driven wheels 51 on the tail-end belt threading path are the ending positions of the two belt threading paths. The first belt threading path 1 and the second belt threading path 2 extend from the two ends of the driven wheels 51 of the head-end belt threading assembly 8 respectively, and extend to the tail-end belt threading assembly 9, winding around the two driven wheels 51 to form the first belt threading path 1 and the second belt threading path 2. The wire 7 connected to the first belt threading path 1 is wound on the winding structure of the head-end belt threading assembly 8, on the winding assembly 4 on one side of the winding structure, through the adjusting guide wheel 41, the fixed guide wheel 42, the connecting winding wheel 43 and the auxiliary connecting wheel 44 to form the first head-end buffer path; the wire 7 connected to the second belt threading path 2 is on the winding structure of the head-end belt threading assembly 8 on the opposite side, similar to the wire 7 extending from the first belt threading assembly, bypassing the adjusting guide wheel 41, the fixed guide wheel 42, and the connecting winding wheel 43 to form the second head-end buffer path. The wire 7 extending from the tail end threading assembly 9 of the two threading paths is wound on the winding structure of the tail end threading assembly 9 on one side, bypassing the adjusting guide wheel 41, the fixed guide wheel 42, the connecting winding wheel 43 and the auxiliary connecting wheel 44 to form a first head and tail end buffer path; the wire 7 connected to the second threading path 2 is similar to the wire 7 extending from the first threading assembly on the winding structure of the tail end threading assembly 9 on the opposite side, bypassing the adjusting guide wheel 41, the fixed guide wheel 42, and the connecting winding wheel 43 to form a second tail end buffer path. At the same time, the second tail end buffer path also includes a path formed by the connecting winding wheel 43 on one side of the head end threading assembly 8 to the connecting winding wheel 43 on the other side. The second tail buffer belt path also includes a path formed by the connecting winding wheel 43 on one side of the tail end threading assembly 9 to the connecting winding wheel 43 on the other side. Finally, the wire 7 extending from the first head end buffer path formed on one side of the head end threading assembly 8 is connected with the wire 7 extending from the second tail end threading path on the tail end threading assembly 9 through the connecting wire reel 43 on one side and the auxiliary connecting wheel 44 on one side, forming a second connection path 23.
