Description

Technical Field

[0001] This invention relates to the field of mechanical winding equipment technology, specifically to an automatic foil winding machine for non-woven semi-dry adhesive tape used in transformer manufacturing. Background Technology

[0002] In the field of mechanical manufacturing, screw-type workpieces often require the wrapping of non-woven semi-dry adhesive tape to improve structural strength and wear resistance. Traditionally, this process relies on lathes and manual labor. The specific operation procedure is as follows: one end of the screw is clamped onto the lathe chuck, and the other end is fixed by the tailstock center. The operator holds the non-woven semi-dry adhesive tape with their left hand and wraps it back and forth as the lathe rotates. The fingers act as the tape support axis, and the thumb adjusts the wrapping tightness.

[0003] This traditional operating mode has many drawbacks: First, manual control of the tightness leads to inconsistent workpiece winding tightness, requiring frequent caliper measurements of thickness, resulting in poor product consistency; Second, when the lathe stops, the motor will continue to rotate due to inertia after the emergency stop button is triggered, and the high gear torque when the clutch is in neutral also results in inertial rotation, and over-clutching can easily cause the machine to reverse, causing personal injury; Third, operation requires experienced personnel and a high degree of concentration, making it a high-barrier and high-risk operation.

[0004] Existing technologies lack dedicated automated equipment for winding non-woven semi-dry adhesive tape, which cannot simultaneously solve multiple problems such as quality and safety. Therefore, there is an urgent need for a dedicated device that can achieve automated winding, ensure safety and quality, and reduce energy consumption. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic foil winding machine for transformer manufacturing using non-woven semi-dry adhesive tape, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic foil winding machine for transformer manufacturing using a non-woven semi-dry adhesive tape, comprising a worktable, a control terminal on the inner side of the worktable, a first motor fixedly mounted on the top of the worktable, an electric gripper on the output shaft of the first motor, a sliding seat slidably connected to the top of the worktable, a pin on the inner side of the sliding seat, a tightening bolt threaded to the bottom of the sliding seat, and an automatic winding mechanism on the top of the worktable; the automatic winding mechanism comprises a second motor, a support, and a movable seat, the second motor being fixedly mounted on the top of the worktable, the support being fixedly connected to the top of the worktable, a threaded rod rotatably connected to the inner side of the support, and the movable seat being slidably connected to the worktable. At the top of the platform, a threaded sleeve is fixedly connected to the front end of the movable seat, a connecting column is fixedly connected to the top of the movable seat, and a mounting column is fixedly connected to the front end of the connecting column. A sliding groove is formed on the surface of the mounting column, and a compression spring is installed inside the sliding groove. A clamping block is slidably connected inside the sliding groove through the compression spring. A ball bearing is installed on the top of the clamping block. A hydraulic piston chamber is fixedly connected through the side of the mounting column, and a connecting chamber is fixedly connected through the top of the hydraulic piston chamber. A piston rod A is slidably connected inside the connecting chamber, and a piston rod B is slidably connected inside the hydraulic piston chamber. A non-woven semi-dry adhesive tape is sleeved on the surface of the clamping block, and an anti-fall-off mechanism is provided on the top of the clamping block. A damping and deceleration mechanism is provided inside the sliding groove.

[0007] According to the above technical solution, the output shaft of the second motor is fixedly connected to the threaded rod, and the threaded sleeve is threadedly connected to the threaded rod. Turning on the second motor can drive the threaded rod to rotate, and the rotation of the threaded rod will cooperate with the threaded sleeve to drive the moving seat to move laterally.

[0008] According to the above technical solution, the end of the clamping block away from the slide groove is set as an inclined surface. The top of the ball initially contacts the inner side of the non-woven semi-dry adhesive tape. The clamping block, together with the compression spring and the ball, will simply limit the non-woven semi-dry adhesive tape, and the ball allows the non-woven semi-dry adhesive tape to continue to rotate.

[0009] According to the above technical solution, the diameter of the connecting chamber is smaller than the diameter of the hydraulic piston chamber. The end of the piston rod A away from the connecting chamber is fixedly connected to the abutment block. When the piston rod B moves to the right, it will drive the piston rod A in the connecting chamber to move downward through the hydraulic pressure in the hydraulic piston chamber. The downward movement of the piston rod A can drive the abutment block to move downward.

[0010] According to the above technical solution, the anti-fall-off mechanism includes an opening groove, a connecting rod, and a toothed rod B. The opening groove is opened at the top of the abutting block, and a sliding rod is slidably connected through the bottom of the opening groove. A sliding cylinder is fixedly connected to the top of the sliding rod, and a telescopic spring is provided inside the sliding cylinder. An arc block is slidably connected inside the sliding cylinder through the telescopic spring. A toothed rod A is fixedly connected to the bottom of the sliding rod, and a gear is fixedly connected to the surface of the connecting rod. The toothed rod B is fixedly connected to the top of the hydraulic piston chamber.

[0011] According to the above technical solution, the end of the arc block away from the telescopic spring initially protrudes from the top of the abutment block, the arc surface of the arc block faces the inclined surface of the abutment block, the straight surface of the arc block can prevent the non-woven semi-dry adhesive tape from detaching from the abutment block, and the arc surface of the arc block will retract into the interior of the slide cylinder when it is squeezed.

[0012] According to the above technical solution, the rack A meshes with the gear, the teeth on the rack B are matched with the teeth on the gear, the friction between the arc block and the slide is less than the friction between the slide and the opening groove, when the gear moves downward it will mesh with the rack B and thus rotate, when the gear rotates it will drive the rack A to move downward relative to the gear, when the arc surface of the arc block is squeezed and moves into the slide, it will not drive the slide to move downward.

[0013] According to the above technical solution, the damping and retardation mechanism includes a fixed column, a connecting pipe is provided on the surface of the fixed column, a one-way valve is provided inside the connecting pipe, and a damping component is provided inside the fixed column.

[0014] According to the above technical solution, the damping component includes a first oil chamber, a second oil chamber, and a connecting chamber. The first oil chamber, the second oil chamber, and the connecting chamber are all opened inside the fixed column. Hydraulic oil is provided inside the first oil chamber and the second oil chamber. A piston rod C is slidably connected inside the first oil chamber, and a piston rod D is slidably connected inside the second oil chamber.

[0015] According to the above technical solution, the two ends of the connecting pipe are respectively connected to the first oil chamber and the second oil chamber. The first oil chamber and the second oil chamber are connected through a connecting cavity. The diameter of the connecting cavity is smaller than the diameter of the first oil chamber and the second oil chamber. The hydraulic oil in the first oil chamber can flow into the second oil chamber through the connecting pipe and the connecting cavity. When the hydraulic oil in the second oil chamber flows into the first oil chamber only through the smaller diameter connecting cavity, it will be subject to greater hydraulic resistance.

[0016] This invention provides an automatic foil winding machine for transformer manufacturing using a non-woven semi-dry adhesive tape. It has the following advantages:

[0017] (1) By setting up an automatic winding mechanism, when it is necessary to wind the screw with non-woven semi-dry adhesive tape, the non-woven semi-dry adhesive tape can be placed on the surface of four sets of clamping blocks from right to left. The clamping blocks, together with the compression spring and the ball, will limit the non-woven semi-dry adhesive tape in a simple way, similar to a lathe chuck. Then, the end of the non-woven semi-dry adhesive tape is wound around the screw held by the electric gripper. The first motor and the second motor are turned on. The first motor drives the screw held by the electric gripper to rotate, and the second motor drives the threaded rod to rotate, causing the moving seat to move laterally. At this time, the non-woven semi-dry adhesive tape rotates under the action of traction force and is wound around the surface of the screw, achieving uniform winding without manual intervention.

[0018] (2) By setting up an anti-detachment mechanism, the present invention allows the non-woven semi-dry adhesive tape to be placed on the surface of four sets of clamping blocks from right to left. During the simple limiting process of the non-woven semi-dry adhesive tape by the clamping blocks, compression springs and balls, the straight surface of the arc block can prevent the non-woven semi-dry adhesive tape from accidentally detaching from the clamping block during the winding process. When the piston rod B is pulled to the right to move the four sets of clamping blocks toward the center of the mounting column to remove the non-woven semi-dry adhesive tape, the slide cylinder will drive the arc block to move downward and retract into the opening groove to prevent affecting the removal of the non-woven semi-dry adhesive tape.

[0019] (3) By setting up a damping and slowing mechanism, the present invention allows the piston rod B to be pulled to the right so that the four sets of clamping blocks move toward the center of the mounting column and remove the non-woven semi-dry adhesive tape. When the piston rod B is released and the compression spring rebounds to drive the clamping blocks to return to their original position, the first oil chamber, the second oil chamber, the connecting chamber and other structures will provide greater hydraulic resistance to prevent the compression spring from driving the clamping blocks to bounce back quickly and cause personal injury. At the same time, it can also prevent the compression spring from driving the clamping blocks to bounce back and forth. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figures 1-10One embodiment of the present invention is as follows: an automatic foil winding machine for non-woven semi-dry adhesive tape used in transformer manufacturing, comprising a worktable 1, a control terminal 2 disposed on the inner side of the worktable 1, a first motor 3 fixedly mounted on the top of the worktable 1, an electric gripper 4 disposed on the output shaft of the first motor 3, a sliding seat 5 slidably connected to the top of the worktable 1, a pin 6 disposed on the inner side of the sliding seat 5, a tightening bolt 7 threadedly connected to the bottom of the sliding seat 5, and an automatic winding mechanism 8 disposed on the top of the worktable 1; the automatic winding mechanism 8 comprises a second motor 81, a bracket 82, and a movable seat 84, the second motor 81 being fixedly mounted on the top of the worktable 1, and the bracket 82 being fixedly connected to the worktable 1. At the top, a threaded rod 83 is rotatably connected to the inner side of the bracket 82. A movable seat 84 is slidably connected to the top of the worktable 1. A threaded sleeve 85 is fixedly connected to the front end of the movable seat 84. The output shaft of the second motor 81 is fixedly connected to the threaded rod 83. The threaded sleeve 85 is threadedly connected to the threaded rod 83. Turning on the second motor 81 can drive the threaded rod 83 to rotate. The rotation of the threaded rod 83, in conjunction with the threaded sleeve 85, drives the movable seat 84 to move laterally. A connecting post 86 is fixedly connected to the top of the movable seat 84. A mounting post 87 is fixedly connected to the front end of the connecting post 86. A groove 88 is formed on the surface of the mounting post 87. A compression spring 89 is installed inside the groove 88. An internal clamping block 810 is slidably connected via a compression spring 89. A ball bearing 811 is located on the top of the clamping block 810. A hydraulic piston chamber 812 is penetrated and fixedly connected to the side of the mounting post 87. A connecting chamber 813 is penetrated and fixedly connected to the top of the hydraulic piston chamber 812. A piston rod A814 is slidably connected inside the connecting chamber 813. A piston rod B815 is slidably connected inside the hydraulic piston chamber 812. The diameter of the connecting chamber 813 is smaller than the diameter of the hydraulic piston chamber 812. The end of the piston rod A814 furthest from the connecting chamber 813 is fixedly connected to the clamping block 810. When the piston rod B815 moves to the right, it will be driven by the hydraulic pressure within the hydraulic piston chamber 812. The piston rod A814 inside the receiving chamber 813 moves downward, which can drive the pressing block 810 to move downward. The surface of the pressing block 810 is fitted with a non-woven semi-dry adhesive tape 816. The end of the pressing block 810 away from the slide groove 88 is set as an inclined surface. The top of the ball 811 initially abuts against the inner side of the non-woven semi-dry adhesive tape 816. The pressing block 810, together with the compression spring 89 and the ball 811, will provide a simple limit to the non-woven semi-dry adhesive tape 816, and the ball 811 allows the non-woven semi-dry adhesive tape 816 to continue to rotate. The top of the pressing block 810 is provided with an anti-drop mechanism 9, and the inside of the slide groove 88 is provided with a damping and deceleration mechanism 10.

[0033] In use, the electric gripper 4 clamps one end of the screw. After loosening and tightening the bolt 7, the sliding seat 5 moves, causing the ejector pin 6 to contact the other end of the screw, thus maintaining the stability of the screw. The non-woven semi-dry adhesive tape 816 is placed on the surface of the four sets of clamping blocks 810 from right to left. Initially, the inner side of the non-woven semi-dry adhesive tape 816 contacts the inclined surface of the four sets of clamping blocks 810 and generates pressure, causing the four sets of clamping blocks 810 to move towards the center of the mounting post 87. The compression spring 89 is compressed. Subsequently, the non-woven semi-dry adhesive tape 816 moves to the ball bearing 811, and the pressure is released. The clamping block 810, in conjunction with the compression spring 89 and the ball bearing 811, provides a simple limit to the non-woven semi-dry adhesive tape 816, while the ball bearing 811 allows the non-woven semi-dry adhesive tape 816 to continue rotating. The end of the non-woven semi-dry adhesive tape 816 is then wound around the screw held by the electric gripper 4. The first motor 3 and the second motor 81 are then activated. The first motor 3 drives the screw held by the electric gripper 4 to rotate, and the second motor 81 drives the threaded rod 83 to rotate. The rotation of the threaded rod 83, in conjunction with the threaded sleeve 85, causes the moving seat 84 to move laterally. 4. Lateral movement drives the connecting post 86 and the mounting post 87 to move, thereby driving the non-woven semi-dry adhesive tape 816 to move laterally. At this time, the non-woven semi-dry adhesive tape 816 rotates under the action of traction force and wraps around the surface of the screw, achieving uniform winding without manual intervention, and the tension is maintained within the preset range to ensure that all workpieces are wound with consistent tightness. After winding is completed, the non-woven semi-dry adhesive tape 816 can be cut and the screw can be replaced for the next set of winding work. When the non-woven semi-dry adhesive tape 816 is consumed and needs to be removed, pull the piston rod B815 to the right. When piston rod B815 moves to the right, it will drive piston rod A814 in connecting chamber 813 to move into connecting chamber 813 via hydraulic pressure in hydraulic piston chamber 812. The movement of piston rod A814 can drive the pressing block 810 to move, so that the four sets of pressing blocks 810 move back to the center of mounting post 87. Then the used non-woven semi-dry adhesive tape 816 can be removed. When piston rod B815 is released, compression spring 89 drives pressing block 810 and piston rod A814 to move in opposite directions to restore their original positions. Hydraulic pressure drives piston rod B815 to move to the left to restore its original position.

[0034] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the anti-detachment mechanism 9 includes an opening groove 91, a connecting rod 97, and a toothed rod B99. The opening groove 91 is formed at the top of the abutment block 810, and a sliding rod 92 is slidably connected through the bottom of the opening groove 91. A sliding cylinder 93 is fixedly connected to the top of the sliding rod 92. A telescopic spring 94 is provided inside the sliding cylinder 93, and an arc block 95 is slidably connected inside the sliding cylinder 93 through the telescopic spring 94. The end of the arc block 95 away from the telescopic spring 94 initially protrudes from the top of the abutment block 810, and the arc surface of the arc block 95 faces the inclined end of the abutment block 810. The straight surface of the arc block 95 can prevent the non-woven semi-dry adhesive tape 816 from detaching from the abutment. When the arc surface of block 810 and arc block 95 is compressed, it retracts into the interior of slide cylinder 93. A toothed rod A96 is fixedly connected to the bottom of slide rod 92. A connecting rod 97 is fixedly connected to the bottom of the pressing block 810. A gear 98 is fixedly connected to the surface of connecting rod 97. A toothed rod B99 is fixedly connected to the top of hydraulic piston chamber 812. Toothed rod A96 meshes with gear 98, and the teeth on toothed rod B99 match the teeth on gear 98. The friction between arc block 95 and slide cylinder 93 is less than the friction between slide cylinder 93 and opening groove 91. When gear 98 moves downwards, it meshes with toothed rod B99, causing rotation. The rotation of gear 98 drives toothed rod A96 to move downwards relative to gear 98. When the arc surface of the arc block 95 is compressed and moves into the slide cylinder 93, it will not cause the slide cylinder 93 to move downward. The damping and deceleration mechanism 10 includes a fixed column 101, a connecting pipe 102 is provided on the surface of the fixed column 101, a one-way valve is provided inside the connecting pipe 102, and a damping assembly 103 is provided inside the fixed column 101. The damping assembly 103 includes a first oil chamber 1031, a second oil chamber 1032, and a connecting chamber 1033. The first oil chamber 1031, the second oil chamber 1032, and the connecting chamber 1033 are all opened inside the fixed column 101. Hydraulic oil is provided inside the first oil chamber 1031 and the second oil chamber 1032. The first oil chamber 1031 is slidably connected to a... The piston rod C1034 is slidably connected to the piston rod D1035 inside the second oil chamber 1032. The two ends of the connecting pipe 102 are respectively connected to the first oil chamber 1031 and the second oil chamber 1032. The first oil chamber 1031 and the second oil chamber 1032 are connected through the connecting cavity 1033. The diameter of the connecting cavity 1033 is smaller than the diameter of the first oil chamber 1031 and the second oil chamber 1032. The hydraulic oil in the first oil chamber 1031 can flow into the second oil chamber 1032 through the connecting pipe 102 and the connecting cavity 1033. When the hydraulic oil in the second oil chamber 1032 flows into the first oil chamber 1031 only through the smaller diameter connecting cavity 1033, it will encounter greater hydraulic resistance.

[0035] In use, the non-woven semi-dry adhesive tape 816 is placed on the surface of the four sets of clamping blocks 810 from right to left. During the simple limiting process of the non-woven semi-dry adhesive tape 816 by the clamping blocks 810, compression springs 89, and ball bearings 811, the inner side of the non-woven semi-dry adhesive tape 816 initially contacts and presses against the arc surface of the arc block 95. The arc surface of the arc block 95, under pressure, moves into the slide cylinder 93, compressing the telescopic spring 94. At the same time, it does not cause the slide cylinder 93 to move downward. When the non-woven semi-dry adhesive tape 816 passes the arc block 95, the telescopic spring 94 rebounds, causing the arc block 95 to move downward. 5. When the tape re-emits, the straight surface of the arc block 95 prevents the non-woven semi-dry adhesive tape 816 from accidentally detaching from the clamping block 810 during the winding process. When the piston rod B815 is pulled to the right to move the four sets of clamping blocks 810 towards the center of the mounting post 87 to remove the non-woven semi-dry adhesive tape 816, the gear 98 moves downward and meshes with the rack B99, causing it to rotate. When the gear 98 rotates, it drives the rack A96 to move downward relative to the gear 98. The movement of the rack A96 drives the slide rod 92 and the slide cylinder 93 to move, thereby causing the arc block 95 to retract into the opening groove 91, preventing it from affecting the non-woven tape. When the semi-dry adhesive tape 816 is removed, and the compression spring 89 drives the clamping block 810 to return to its original position, the rack B99, in conjunction with the gear 98, drives the rack A96 to return to its original position. The slide rod 92 and the slide cylinder 93 move in opposite directions to return to their original positions, and the arc block 95 protrudes again from the clamping block 810. As the four sets of clamping blocks 810 move toward the center of the mounting post 87, the clamping blocks 810 move downward along the slide groove 88, which will drive the piston rod D1035 to move downward. At this time, the hydraulic oil in the first oil chamber 1031 will flow into the second oil chamber 1032 through the connecting pipe 102 and the connecting cavity 1033. The piston rod C When piston rod C1034 moves downward, the hydraulic resistance is relatively small. When compression spring 89 rebounds and drives the retaining block 810 to return to its original position, piston rod D1035 moves upward. The hydraulic oil in the second oil chamber 1032 flows into the first oil chamber 1031 only through the smaller diameter connecting chamber 1033. When piston rod C1034 moves upward, it will be subject to greater hydraulic resistance. This slows down the rebound speed of compression spring 89 and prevents compression spring 89 from driving the retaining block 810 to bounce back and forth, which could cause personal injury. It also prevents compression spring 89 from driving the retaining block 810 to bounce back and forth.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
