DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0032] like Figure 1-2 As shown, the specific structure of the present invention is: a multi-coil winding equipment, including a frame 1, a winding skeleton mechanism 2 and a pay-off device 6 for placing a wire coil, the winding skeleton mechanism 2 includes a winding seat 11 arranged on the frame 1, a skeleton plate 12 is installed on the winding seat 11 by bolts, and at least two rows of die seat groups are arranged on the skeleton plate 12, each row of die seat groups has at least two die seats 13, and a conductor rod 14 is arranged between adjacent die seat groups. Each die seat 13 is equipped with a winding skeleton, and the winding seat 11 is provided with a wire pressing structure 15 for pressing the end of the wire harness; the winding seat 11 is provided with a winding device 5, the winding device 5 can drive the wire harness to move in the three axes of XYZ so that the wire harness is wound on the winding skeleton in turn, and the winding skeleton includes a core plate 19 passing through the die seat 13, and one end of the core plate 19 passing through the die seat 13 is equipped with a detachable cover plate 20, and the core plate 19 part between the cover plate 20 and the die seat 13 is a winding area.

[0033] The specific winding operation of the multi-link coil of the present application is as follows: first, the starting end of the wire harness of the unwinding device 6 is manually pulled out and passed through the winding device 5, and then the end is pulled to the wire pressing structure 15 and pressed by the end of the wire pressing structure 15, and then the subsequent wire harness can be driven by the winding device 5 to be guided by the guide rod 14 and then wound on the winding skeleton in sequence. Taking four winding skeletons, two in each row as an example, the winding order is lower left, upper left, lower right, and upper right; complete the winding of all winding skeletons (the wire harness is wound between the cover plate 20 and the mold base 13 with a core Plate as the central skeleton for winding), the wire harness can be cut off, and the wire pressing structure 14 can be loosened on the end, and then the cover plate 20 can be removed, and then the core plate 19 can be pulled out, so that the multi-link coil can fall freely. A feed port 7 can be opened on the frame, and a collection box 8 can be placed under the feed port 7, so that the multi-link can be collected, and then the core plate 19 and the cover plate 20 can be installed, and the end can be sent to the wire pressing structure 14 by manual pulling again to complete the end pressing, and then the above winding operation can be repeated to complete the continuous winding of the multi-link coil.

[0034] like Figure 2 As shown, the winding seat 11 is located on both sides of the skeleton plate 12 and is respectively provided with a first wire pressing device 16 and a second wire pressing device 17. The first wire pressing device 16 and the second wire pressing device 17 are used to press the wire harness and energize the wire harness, and a cutter is also provided in the second wire pressing device 17 to press and cut the wire harness after winding is completed; after the wire pressing structure 14 presses the end, the wire harness is first driven by the winding device 5 to pass through the first wire pressing device 16 and is pressed by the first wire pressing device 16, and then the winding is carried out. After the winding of the multi-connected coil is completed, the wire harness is moved to the second wire pressing device 17, pressed by the second wire pressing device 17, and cut off, and then the wire harness is energized by the first wire pressing device 16 and the second wire pressing device 17, so that the wound multi-connected coil can be energized, so that the coil can be shaped, and the multi-connected coil can be cut after shaping. In this process, manual work can be performed to prepare the end wire pulling for the next winding.

[0035] like Figure 3-4 As shown, the upper and lower sides of the parts where the core plate 19 and the cover plate 20 cooperate are provided with pressure block cooperation grooves 25, and the upper and lower ends of the cover plate 20 are provided with rotatable and right-angled pressure blocks 22, one end of the pressure block 22 cooperates with the pressure block cooperation groove 25, and the upper and lower sides of the other end cooperate with the pressure column 23 and the elastic component 24 respectively. When there is no external force on the pressure column 23, the spring component 24 supports the pressure block 22 so that the pressure block 22 is inserted into the pressure block cooperation groove 25.

[0036] In order to facilitate the cutting of the winding skeleton, it is necessary to facilitate the disassembly and assembly of the cover plate 20 and the core plate 19. This solution designs the structure of the joint between the cover plate 20 and the core plate 19. During installation, it is only necessary to press the pressure column 23 inward to compress the spring component 24, so that the pressure block 22 can be rotated outward, so that the cover plate 20 can be directly sleeved on the core plate 19, and then the internal pressure of the pressure column is released. Under the action of the recovery of the spring component 24, the pressure block 22 is rotated inward, and then the pressure block 22 is pressed into the pressure block matching groove 25, so that the clamping of the cover plate 20 and the core plate 19 is completed. When disassembly is required, the pressure column 23 is also pressed inward to compress the spring component 24, so that the pressure block 22 can be rotated outward and come out of the pressure block matching groove 25, and then the cover plate 20 is translated outward to complete the disassembly.

[0037] like Figure 6-8 As shown, the frame 1 is provided with a cover plate movable device 4, and the cover plate movable device 4 includes a cover plate movable seat 31 arranged on the frame 1, and a cover plate movable cylinder 32 is arranged on the cover plate movable seat 31, and the cover plate movable cylinder 32 is connected to a cover plate movable block 33, and a cover plate clamping cylinder 34 is arranged on the cover plate movable block 33, and the cover plate clamping cylinder 34 is connected to two groups of cover plate clamping blocks 35 that can move toward or away from each other, and the cover plate clamping block 35 cooperates with the cover plate clamping opening 21 opened on the cover plate 20, and the cover plate clamping block 35 is provided with a pressure column matching groove 36 that cooperates with the pressure column 23. When the cover plate clamping block 35 is clamped and matched with the cover plate clamping opening 21, the pressure column 23 enters into the pressure column matching groove 36 and is pressed into the cover plate 20 for a section, so that the pressure block 22 rotates and disengages from the pressure block matching groove 25.

[0038] In order to reduce manual operation, the present application designs the cover plate disassembly and assembly into an automatic structure. When disassembly is required, the cover plate clamping cylinder 34 is first used to drive the cover plate clamping block 35 and the cover plate clamping cylinder 34 to translate as a whole, so that the position of the cover plate clamping block 35 corresponds to the cover plate 20, and then the cover plate clamping cylinder 34 is used to drive the cover plate clamping block 35 to move toward each other, so that the cover plate clamping block 35 is clamped to the cover plate clamping opening 21 of the cover plate 20. At this time, the pressure column 23 is in the pressure column matching groove 36 and is pressed inward by the pressure column matching groove 36, so that The spring component 24 is compressed to rotate the pressure block 22 and disengage from the pressure block matching groove 25, and then the cover plate clamping cylinder 34 is used to drive the cover plate clamping block 35 and the cover plate clamping cylinder 34 to translate as a whole, so that the cover plate 20 can be moved away; when the cover plate 20 needs to be assembled, it is only necessary to drive the cover plate clamping block 35 and the cover plate clamping cylinder 34 to translate as a whole through the cover plate clamping cylinder 34, so that the cover plate 20 is sleeved on the core plate 19, and then the cover plate clamping cylinder 34 drives the cover plate clamping block 35 to move backwards, and the installation of the cover plate 20 and the core plate 19 can be completed.

[0039] like Figure 5As shown, a core plate movable device 3 is arranged on the frame 1, and the core plate movable device 3 includes a core plate movable seat 26 arranged on the frame 1, a core plate movable cylinder 27 is arranged on the core plate movable seat 26, and the core plate movable cylinder 27 is connected to a core plate clamping structure 28.

[0040] In order to facilitate material unloading, the core plate is also designed to be an automatically movable structure with a simple structure, and only requires the core plate movable cylinder 27 to drive the core plate clamping structure 28 to move horizontally.

[0041] like Figure 5-6 As described above, all the core plates 19 matched with the same row of mold base groups are clamped by a core plate clamping structure 28, and all the cover plate clamping blocks 35 matched with all the cover plates 20 matched with the same row of mold base groups are matched with the same cover plate clamping cylinder 34.

[0042] The core plates 19 at the same height are driven by the same core plate movable cylinder 27 to move horizontally, and the cover plates 20 at the same height are driven by the same cover plate clamping cylinder 34 to synchronously clamp and place multiple groups of cover plate clamping blocks 35, which can simplify the structure.

[0043] like Figure 9-10 As shown, the winding device 5 includes an X-axis movable structure 41 arranged on the winding seat 11, the X-axis movable structure 41 is connected to the Y-axis movable structure 42, the Y-axis movable structure 42 is connected to the Z-axis movable structure 43, the Z-axis movable structure drives the winding movable seat 44, the upper and lower parts of the winding movable seat 44 are provided with wire wheels 45, and the lower end of the winding movable seat 44 is provided with a wire nozzle 46, the wire harness passes through the wire nozzle 46, and the winding movable seat 44 is provided with a wire clamping structure 47, the wire clamping structure 47 includes a wire clamping seat 48 arranged on the winding movable seat 44, and the wire clamping seat 48 is provided with a wire clamping cylinder 49 perpendicular to the wire harness between the two guide wheels 45, and the wire clamping cylinder 49 is connected to a wire clamping block 50, and the wire clamping block 50 is used to press the wire harness between the two guide wheels 45 onto the winding movable seat 44.

[0044] The winding structure is operated as follows: first, manually pass the wire harness end of the wire-releasing device 6 through the upper and lower wire wheels 45 in sequence, and then pass through the wire nozzle 46, and then be pressed by the wire pressing structure 14. After that, the wire nozzle 46 can be driven by the three-axis motion structure to perform three-axis motion, so that the wire harness can be driven to wind on the winding frame. Through the cooperation of the wire wheel and the wire nozzle 46, the wire harness can be well controlled to run according to the trajectory set by the three-axis motion structure to achieve precise winding. After the winding of the multiple coils is completed, the wire clamping block 50 is driven to move by the wire clamping cylinder 49, and then the wire harness between the two guide wheels 45 is pressed against the winding movable seat 44 by the wire clamping block 50, and then the wire harness is cut. In this way, when winding the next group of multiple coils, it is ensured that the wire harness end will not move randomly, which is convenient for manual wire pulling.
