Description

Technical Field

[0001] The invention relates to the technical field of coils, and in particular to a coil production system. Background Art

[0002] The motor coil is one of the indispensable parts in the production of micro motors. The motor coil is wound by enameled wire. The coil manufacturing process includes winding, flattening, wire end removal, wire management and other processes. For example, the patent with announcement number CN202749982U discloses a motor coil winding machine, including a wire management mechanism, a winding mechanism and a wire clamping mechanism installed on a frame for clamping the wire. The wire management mechanism is provided with a positioning mechanism for positioning the coil frame. The wire clamping mechanism is arranged between the wire management mechanism and the positioning mechanism. The wire management mechanism and the winding mechanism automatically wind the wire around the PIN pin of the coil frame and the coil frame, and the wire is clamped off by the wire clamping mechanism after winding.

[0003] During the coil winding process, the coil volume is small and the copper wire is thin. After the coil winding is completed, the coil wire ends are in a chaotic irregular bending state. Therefore, the coil wire ends need to be straightened and then inserted into the molten tin solution to coat the wire ends with tin solder. For example, the patent with publication number CN102647053A discloses an automatic straightening device for the wire ends of micro motor coils. The clamp with the coil clamped is automatically transferred to the blowing device, and the wire ends on the coil are automatically straightened with high-pressure gas. Although it reduces the use of manual labor to a certain extent and improves the process efficiency, it needs to use high-pressure gas with a pressure of 0.45 to 0.6 MPa during use. If it is not operated properly, it is very easy to affect the safety of the entire device. Summary of the invention

The clamping jaw 622 includes a clamping jaw arm 6221 and a clamping jaw hand 6222 which are fixedly connected in sequence. In this embodiment, the clamping jaw arm 6221 and the clamping jaw hand 6222 are integrally formed, and one end of the clamping jaw arm 6221 is fixedly connected to the bottom end of the side wall of the clamping jaw frame 621. In this embodiment, the cross-section of the clamping jaw hand 6222 is L-shaped, and the top end of the clamping jaw hand 6222 is located on the clamping jaw arm 6221. An arc-shaped groove is arranged at the bottom end of the clamping jaw hand 6222. The bottom end of the clamping jaw hand 6222 encloses a cavity 623 for accommodating a coil. A gap is left between the bottom end of the clamping jaw hand 6222 and the clamping frame 621, and the positioning column 611 is located directly below the cavity 623.

[0082] The top of the clamping frame 621 is fixedly connected to the clamping plate 624 through the support base 627; a through hole is provided on the top wall of the clamping plate 624, one end of the guide rod 625 passes through the through hole, and the clamping plate 624 is movably sleeved on the guide rod 625. The piston end of the seventh cylinder is fixedly connected to the bottom end of the clamping plate 624.

[0083] In order to improve the degree of automation of the coil production system in this embodiment, a control device is also included. The control device in this embodiment is the existing technology. The winding device 1, the flattening device 2, the wire cutting device 3, the heating device 4, the rounding device 5 and the wire sorting device 6 are all electrically connected to the control device.

[0084] The working principle of this embodiment is as follows: the enameled wire passes through the tensioner and enters the wire nozzle from the tensioner, the first motor 112 drives the winding die 111 to rotate, thereby winding the enameled wire on the wire nozzle onto the winding die 111, and the first cylinder drives the wire nozzle to move back and forth along the axis of the winding die 111, so that the enameled wire is wound onto the winding die 111 along the axis of the winding die 111.

[0085] During the winding process of the enameled wire, the hook needle 131 is driven by the first XYZ three-axis moving unit to hook the enameled wire, and the third motor drives the hook needle 131 to rotate to twist the enameled wire into an electrode head. During the twisting process, in order to prevent the coil on the winding mold 111 from moving, the second cylinder is extended and retracted to drive the fixed plate 122 to move toward the winding mold 111, and the pressure block is pressed on the side wall of the coil.

[0086] After the coil is wound, the second XYZ three-axis moving unit 22 drives the clamping and flattening manipulator to move to the winding die 111, and the clamping piece 211 moves to both sides of the coil, clamps the coil through the fourth cylinder, removes the coil from the winding die 111, and then clamps the coil through the fourth cylinder to flatten the coil.

[0087] The flattened coil is moved by the second XYZ three-axis moving unit 22 to the opening of the first tool 32, the fifth cylinder drives the first tool 32 and the second tool 33 to move relative to each other, the second tool 33 moves into the opening of the first tool 32, and the first tool 32 and the second tool 33 cooperate to cut off the excess thread ends on the coil.

[0088] The second XYZ three-axis moving unit 22 drives the clamping piece 211 to move into the cavity of the heating device 4, and the heating block 41 heats the coil after being clamped flat, and the heated coil is transferred to the rotating shaft 511 by the first manipulator. The rounding cylinder 512 completes the rounding work in sequence, the tape rolling cylinder drives the tape conveyor 515 to move toward the rotating shaft 511, and the tape is adhered to the initially rounded coil. The tape pressing block cylinder drives the tape pressing block to move toward the rotating shaft 511 to press the tape on the coil, and the rotating cylinder rotates to drive the tape to be wound around the coil.

[0089] The rounded coil is grasped by the second manipulator and moved to the positioning column 611 through the fourth moving unit of the XYZ three-axis. The seventh cylinder drives the clamping plate 624 to move up and down along the guide rod 625, thereby driving the clamping plate 624 to move up and down, and the clamping arm 6221 moves downward, and the clamping hand 6222 moves toward the positioning column 611, adjusting the moving distance and the size of the cavity 623 to allow the coil to enter the cavity 623, and the clamping arm 6221 moves upward, thereby automatically straightening the coil ends of a fixed size.

[0090] Beneficial effects of this embodiment: This embodiment adopts a winding device 1 to wind the coil, adopts a flattening device 2 to flatten the coil, adopts a wire cutting device 3 to cut off excess wire ends on the coil, adopts a heating device 4 to heat the flattened coil, adopts a rounding device 5 to round the heated coil, and uses a wire sorting device 6 to straighten the coil wire ends, which can replace manual labor, reduce the workload of the staff, and ensure the consistency of the coil assembly quality. The production system in this embodiment can automatically straighten the coil wire ends without using high-pressure gas, which can improve the safety of the device and reduce the safety risks of the operators.

[0091] Example 2

[0092] The difference between this embodiment and embodiment 1 is that: Fig.10 and Fig.11 As shown, the top end of the clamp arm 6221 is rotatably connected to the clamp frame 621 , and also includes a buffer adjustment unit, a retaining spring 632 and a baffle 626 . The positioning mechanism also includes a top claw 613 and an eighth cylinder 614 .

[0093] The buffer adjustment unit includes a buffer positioning member. In this embodiment, the buffer positioning member is a ball plunger 631. The head of the ball plunger 631 is located inside the side wall of the clamp frame 621, and the tail of the ball plunger 631 passes through the side wall of the clamp arm 6221 and is installed on the side wall of the clamp arm 6221. The installation method of the ball plunger 631 is the existing technology.

[0094] The side wall of the clamp arm 6221 is hinged to the side wall of the clamp frame 621, and the clamp frame 621 is fixedly installed with a fixing seat facing the side wall of the clamp arm 6221. A through hole is opened in the side wall of the fixing seat, and the side wall of the clamp arm 6221 is provided with a groove. The fixing seat is located in the groove, and a rotating shaft 511 (not shown) is installed in the through hole. One end of the rotating shaft 511 passes through the clamp arm 6221 and the through hole, and the other end of the rotating shaft 511 extends to the outer wall of the clamp arm 6221. Baffles 626 are fixedly installed at both ends of the rotating shaft 511.

[0095] A retaining spring 632 is installed on the rotating shaft 511 . The installation and adjustment methods of the retaining spring 632 are prior art. The degree of opening and closing of the clamping claw hand 6222 is adjusted by arranging the retaining spring 632 in cooperation with the ball plunger 631 .

[0096] One end of the top claw 613 is fixedly connected to the telescopic end of the eighth cylinder 614, and the connection method is the existing technology. The top claw 613 is located on one side of the positioning column 611. The eighth cylinder 614 is telescopic to make the top claw 613 close to or away from the bottom end of the coil side wall. The eighth cylinder 614 is installed on the fixed block 612. In order to reduce the influence of the top claw 613 on the wire arrangement, the top claw 613 is wedge-shaped, and the smaller end of the top claw 613 is set close to the positioning column 611.

[0097] The working principle of this embodiment is as follows: according to the coils of different specifications, the ball plunger 631 is turned to adjust the distance between the clamp arm 6221 and the clamp frame 621, thereby adjusting the opening and closing amplitude of the clamp hand 6222. When the distance between the top wall of the clamp arm 6221 and the top wall of the clamp frame 621 increases, the size of the cavity 623 decreases. When the distance between the top wall of the clamp arm 6221 and the top wall of the clamp frame 621 decreases, the cavity 623 increases, so that the cavity 623 for accommodating the coil formed between the clamp hands 6222 can match the coil. Then the seventh cylinder is started to drive the clamp arm 6221 to move downward, so that the clamp hand 6222 moves toward the positioning column 611, and the coil enters the cavity 623. Then the seventh cylinder drives the clamp arm 6221 to move upward, thereby straightening the coil thread ends.

[0098] Beneficial effects of this embodiment: by providing the ball plunger 631, one end of the clamp arm 6221 is rotatably connected to the clamp frame 621, so that the distance between the clamp arm 6221 and the clamp frame 621 can be adjusted, thereby straightening the wire ends of coils of different specifications.

[0099] By extending the eighth cylinder 614 and pressing the top claw 613 against the side wall of the coil, the coil can be prevented from following the movement of the clamp hand 6222 when it moves up and down. By extending the eighth cylinder 614 and pressing the top claw 613 against the bottom end of the coil side wall, the top claw 613 can be prevented from affecting the up and down movement of the clamp hand 6222.

In this embodiment, there are two positioning mechanisms and two wire-managing mechanisms. The top claw 613 and the eighth cylinder 614 are located on the same fixed block 612, and the wire ends of two coils can be managed at the same time.

[0102] This embodiment also includes a connecting plate 64. The cross-section of the support base 627 is L-shaped. The connecting plate 64 is installed between the support base 627 and the side wall of the clamping claw plate 624. The two support bases 627 are connected by the connecting plate 64. The piston end of the seventh cylinder (not shown) is fixedly connected to the bottom end of the connecting plate 64, and the clamping claw arm 6221 is driven to move up and down at the same time by the seventh cylinder.
