[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic winding equipment for power transformer production involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-3 An automatic winding device for power transformer production includes an outer frame 1, a first motor 2 fixedly installed at the top of the outer frame 1, a drive screw 3 fixedly installed on the output shaft of the first motor 2, a limit rod 4 fixedly installed inside the outer frame 1, a vertical plate 5 fixedly installed at the bottom of the outer frame 1, a side assembly 6 fixedly installed on one side of the vertical plate 5, a first track rod 7 and a second track rod 8 fixedly installed on the vertical plate 5 respectively, a secondary track rod 9 movably installed at one end of the first track rod 7, an unlocking assembly 10 fixedly installed at the upper and lower ends of the outer frame 1 respectively, a wire harness placement cylinder 11 movably sleeved on the drive screw 3 and the limit rod 4, and a winding support assembly 12 placed on the first track rod 7 and the second track rod 8.

[0031] Compared with existing technologies, this application, by setting up a winding support assembly 12 that can be conveyed and fitted with an outer cylinder, utilizes a side component 6 to lock the winding support assembly 12 after it moves to the corresponding position. The side component 6 then drives the winding support assembly 12 and the outer cylinder to rotate, thus enabling the winding of the wire harness released from the wire harness placement cylinder 11. Furthermore, the wire harness placement cylinder 11, driven by the first motor 2, drives the drive screw 3 to rotate, achieving a uniform and slow movement of the wire harness placement cylinder 11 on the drive screw 3. By simply changing and adjusting the pitch of the drive screw 3 and the speed of the first motor 2, various wire harness winding requirements can be met, greatly increasing the applicability of the equipment. The vertically moving wire harness placement cylinder 11 also enables continuous winding of the wire harness, significantly improving the efficiency of the equipment. Additionally, by setting up an adjustable winding support assembly 12, the outer cylinder is fitted onto the winding support assembly 12, and then pushed... The wire is fed to the side assembly 6 for winding. After the winding support assembly 12 is connected, it can be locked by inserting the core rod 124 at the bottom with the pin head 69. This allows the drive of the inner motor 66 to be transmitted to the winding support assembly 12 for overall rotation and winding. After insertion, the core rod 124 moves upward, causing the inner support structure 128 to unfold and support the outer cylinder, ensuring the stability of the outer cylinder and the winding effect. After winding, the movement of the wire harness placement cylinder 11 drives the unlocking assembly 10 to transmit the downward push rod 1210, which in turn causes the pin head 69 to retract. In this way, during the subsequent feeding process of the winding support assembly 12, the wound outer cylinder can be pushed out for unloading. Before pushing out, the wire harness is cut by the cutting knife 64, so that the wound outer cylinder can be discharged before winding another outer cylinder, so as to replenish the wound outer cylinder in time, ensuring the continuous operation of the entire equipment and further improving the efficiency of the equipment.

[0032] Please see Figures 1-5 An automatic winding device for power transformer production includes a side assembly 6, which includes a side bracket 61. A short rod 62 is fixedly installed on one side of the side bracket 61, and a hydraulic telescopic rod 63 is fixedly installed at one end of the side bracket 61. A cutting blade 64 is fixedly installed at the end of the hydraulic telescopic rod 63. A tray 65 is fixedly installed at one end of the short rod 62. An internal motor 66 is installed in the middle of the tray 65. A mating protrusion 67 is fixedly installed on the output shaft of the internal motor 66. A groove is opened at one end of the mating protrusion 67, and a first spring 68 is fixedly installed in the groove. A pin head 69 is fixedly installed at one end of the first spring 68.

[0033] In this embodiment, it should be noted that the other end of the side bracket 61 is fixedly installed on the outer side of the upright plate 5, the cutting blade 64 is set at the height of the middle part of the tray 65, the internal motor 66 is a dual-axis motor, one end of the interlocking protrusion 67 is flush with the surface of the tray 65, the upper and lower edges of the tray 65 are rounded, the pin head 69 protrudes from the top of the interlocking protrusion 67 when no external force is applied, and the number of thread turns in the middle part of the drive screw 3, which is the same length as the height of the tray 65, is less than one turn. In this way, the surface of the tray 65 forms a support connection to the end of the winding support assembly 12, and then the internal... The internal motor 66 rotates to drive the pin head 69 to rotate, which in turn drives the winding support assembly 12 to rotate as a whole to wind the wire harness. Under the drive of the first motor 2, the drive screw 3 rotates, which also drives the wire harness placement cylinder 11 to move up and down. This realizes the automatic winding of the wire harness. Since the winding support assembly 12 can be set at both the upper and lower ends of the tray 65, the winding support assembly 12 at the upper and lower ends can be wound separately. That is, after one end is wound, the winding support assembly 12 at the other end can be wound without stopping the machine, and the winding support assembly 12 at the end that has been wound can be removed at the same time, which greatly improves the working efficiency of the equipment.

[0034] Please see Figures 1-3 An automatic winding device for power transformer production includes an unlocking component 10. The unlocking component 10 includes a limiting short rod 101. A pressure rod 102 is movably sleeved on the limiting short rod 101. A connecting rope 103 is fixedly installed in the middle of one side of the pressure rod 102. An elastic rope 104 is fixedly installed in the middle of the other side of the pressure rod 102. A connecting rod 105 is fixedly installed at one end of the elastic rope 104.

[0035] In this embodiment, it should be noted that the limiting short rod 101 is fixedly installed on the inner upper and lower surfaces of the outer frame 1, one end of the pressure rod 102 is located above the middle of the top of the winding support assembly 12, one end of the connecting rope 103 is fixedly connected to the outer frame 1, and the connecting rod 105 is fixedly connected to the end of the wire harness placement cylinder 11. After winding is completed on a winding support assembly 12, the pressure rod 102 can be pulled to move under the reverse movement of the wire harness placement cylinder 11 until one end of it presses down on the end of the winding support assembly 12, thereby achieving the locking and limiting of the winding support assembly 12 and the upright plate 5. This ensures that the two can be separated for unloading, and also facilitates the subsequent reinstallation of the winding support assembly 12 that needs to be wound, ensuring the continuity of use of the entire device.

[0036] Please see Figures 2-10An automatic winding device for power transformer production includes a winding support assembly 12, which includes a chassis 121. A support ring 122 is fixedly installed on the outer side of the chassis 121. A vertical insertion rod 123 is fixedly installed on the upper surface of the chassis 121. A core rod 124 is movably sleeved on the vertical insertion rod 123. A limit slot 125 is opened on the side of the core rod 124. A docking groove 126 is opened at the bottom end of the core rod 124. A vertical rod 127 is movably installed inside the core rod 124. An inner support structure 128 is fixedly installed at the top of the chassis 121. A cover plate 129 is installed at the top of the inner support structure 128. A push rod 1210 is movably installed in the middle of the cover plate 129.

[0037] In this embodiment, it should be noted that the edge of the chassis 121 that contacts the tray 65 has a rounded corner structure. The support ring 122 is supported and suspended on the first track rod 7 and the second track rod 8. The auxiliary track rod 9 is rotatable around one end of the first track rod 7, and the distance between the rotatable end and the opposing second track rod 8 is the same as the diameter of the chassis 121. An inner spring is connected at the connection between the vertical insertion rod 123 and the core rod 124. The bottom end of the core rod 124 penetrates the chassis 121 and is provided with a protrusion. When the bottom end of the core rod 124 contacts the surface of the chassis 121, the protrusion extends out to the other side of the chassis 121. The cross-section of the mating groove 126 and the cross-section of the mating protrusion 67 are both regular polygons and are compatible. The bottom end of the vertical rod 127 is provided with an end block inside the mating groove 126, and the shape and size of the end block are the same as the cross-sectional shape and size of the mating groove 126. The top end of the vertical rod 127 is also provided with... The end block, push rod 1210, and the top of the inner support structure 128 are detachably abutted. This allows the rounded corners of the base 121 to prevent conflict when it moves to the position of the tray 65. The rounded corners of the base 121 also ensure downward pressure on the pin head 69, allowing the pin head 69 to smoothly align with the docking slot 126. This enables the inner motor 66 to drive the winding support assembly 12 to rotate and wind the wire harness. After the pin head 69 is aligned, it also lifts the vertical rod 127, facilitating the unlocking process after winding by pressing the pin head 69 with the unlocking component 10. This ensures the normal loading and unloading of the winding support assembly 12. After the base 121 aligns with the tray 65, the core rod 124 moves upward, allowing the inner support structure 128 to extend and support the outer cylinder, ensuring the stability and reliability of the winding process.

[0038] Please see Figures 8-9An automatic winding device for power transformer production includes an inner support structure 128, which includes a base plate 1281. A support rod 1282 is fixedly installed on the lower surface of the base plate 1281. A crossbar 1283 is movably installed on the support rod 1282. A second spring 1284 is fixedly installed inside the crossbar 1283. A support plate 1285 is fixedly installed at one end of the crossbar 1283.

[0039] In this embodiment, it should be noted that the base plate 1281 has a threaded groove in the middle, and the cover plate 129 has a protruding rod in the middle of the side near the base plate 1281. The protruding rod also has a threaded groove on its outside, and the two can be threadedly connected. The push rod 1210 has end blocks at both ends, and the bottom end block can abut against the vertical rod 127. The bottom end of the support rod 1282 is fixedly connected to the surface of the base plate 121. The support rods 1282 are arranged in pairs, and each pair is located at the position of the horizontal rod 1283. The crossbar 1283 is movably inserted into the crossbar and slidably set. The two ends of the second spring 1284 are respectively fixedly installed inside the crossbar 1283 and on the crossbar, and are retracted when not under force. In this way, after the winding support assembly 12 is connected to the side assembly 6, the core rod 124 can be lifted by the interlocking protrusion 67, thereby causing one end of the crossbar 1283 to be supported and unfolded. In this way, the support plate 1285 can support the outer cylinder in the center, thereby ensuring stability and reliability in the subsequent winding process.

[0040] Working principle: The outer cylinder to be wound is placed on the winding support assembly 12, and then the winding support assembly 12 is placed on the first track rod 7 and the second track rod 8. When pushed above the tray 65, the surface of the tray 65 will first squeeze the core rod 124 to contract, thereby causing the end of the horizontal rod 1283 to disengage from the limiting slot 125, and then support the outer cylinder in an unfolded shape. At the same time, after the pin head 69 is inserted into the docking slot 126, it will abut against the vertical rod 127 and move upward, forming a lock with the core rod 124. The inner motor 66 is started to drive the mating protrusion 67 to rotate, thereby driving the entire winding support assembly 12 to rotate. The wire harness extending from the wire harness reel placed on the wire harness placement cylinder 11 is wound onto the winding support assembly 12 during the rotation of the winding support assembly 12. At the same time, the first motor 2 will also drive the drive screw 3 to rotate, thereby driving the wire harness placement cylinder 11 to release the wire harness. Simultaneously, the wire harness moves up and down synchronously to achieve automatic winding. After winding on the winding support assembly 12 on one side of the tray 65, the wire harness placement cylinder 11 moves to the winding support assembly 12 on the other side after passing the tray 65. The wire harness is then fixed in the original slot of the outer cylinder on the winding support assembly 12. As it rotates, it moves to the position of the cutting knife 64. The hydraulic telescopic rod 63 is activated to drive the cutting knife 64 to move and cut the wire harness wound on the tray 65. During the subsequent downward movement, the connecting rod 105 pulls the elastic rope 104 to drag the pressure rod 102 until it squeezes the push rod 1210. This causes the push rod 1210 to squeeze the vertical rod 127 downward and push the pin head 69 out of the docking groove 126, thereby releasing the lock between the winding support assembly 12 and the side assembly 6. Then, the outer cylinder of the winding number is discharged, and the winding support assembly 12 is replenished for the next winding.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
