Description

Technical Field

[0001] The present invention relates to the technical field of coil de-insulation, and particularly to a multi-station laser de-insulation fixing device. Background Art

[0002] In order to achieve a relatively high insulation strength, traction motors generally use copper or aluminum wires with sintered films or coated impregnating varnishes to make windings. After the winding is completed and the wire is inserted, the lead wire heads of the winding need to be welded and connected according to a certain principle. Therefore, it is necessary to remove the insulating layer of the electromagnetic wire used for the winding. Whether the insulating layer of the copper wire uses a film, the glue coated on the film surface cures at a certain temperature, making the film closely adhere to the copper or aluminum wire; if impregnating varnish is used, it is also closely cured with the copper conductor. Then, during on-site production, both the reliability of removal and the operation efficiency need to be considered. Therefore, certain tools or methods must be used to remove this insulating layer.

[0003] In the existing coil de-insulation technology, generally, copper or aluminum wires are held by hand, and the insulation is removed by using operating equipment or other methods. Among them, the manual holding and fixing method has a large manual labor intensity, a cumbersome operation process, and is not convenient for the construction of operating equipment; in addition, when using the existing operating equipment for de-insulation operations, there are also problems with poor insulation removal effects.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] In the case where the operator manually operates the coil, the present invention discloses a multi-station laser insulation removal and fixing device. Among them, the present invention uses a pneumatic fixture to clamp the coil, and a servo motor is used to drive the fixture to rotate a certain angle to drive the coil to rotate, so as to meet the requirements of the laser device for removing the insulation on each surface of the coil lead head. On this basis, a double-station is also designed to alternately switch the loading and unloading station and the working station for cyclic operation, so as to achieve the purpose of shortening the operation time.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0041] The multi-station laser insulation removal and fixing device provided by the embodiment of the present invention, as Figure 1 and Figure 2 shown, includes: a first-station fixing device 100; the first-station fixing device 100 includes:

[0042] a mounting plate 110 for mounting the coil 600;

[0043] a coil side surface fixture 120 disposed on the mounting plate 110 for clamping both side surfaces of the coil 600; based on this clamping structure, the present solution realizes the fixing of the coil 600 in the width direction;

[0044] a coil height direction fixture 130 disposed on the mounting plate 110 for pressing the coil 600 vertically; similarly, based on this pressing structure, the present solution realizes the fixing of the coil 600 in the height direction;

[0045] a coil nose fixture 140 disposed on the mounting plate 110 for clamping the nose 620 of the coil 600 near the lead head 610. Based on this clamping structure, the present solution realizes the fixing of the nose 620 of the coil 600 near the lead head 610.

[0046] From the above technical solutions, it can be seen that in the multi-station laser insulation removal and fixing device provided by the embodiment of the present invention, through the actions of the coil side surface fixture, the coil height direction fixture and the coil nose fixture respectively, the clamping and fixing of the coil in the width direction, height direction and nose part are realized, thereby replacing the manual holding fixing method, effectively reducing the labor intensity of the operator, and at the same time making it more convenient for the laser device to perform insulation removal operations.

[0047] In this solution, as Figure 2 shown, the coil side surface fixture 120 includes:

[0048] Two alignment clamps 121 are provided on the mounting plate 110. This design has the characteristics of simple structure, easy manufacturing, and reliable clamping. Among them, the alignment clamp 121 can be in the shape of a plate, a block, or a column. In order to simplify the manufacturing process of the coil side fixture 120 and reduce its manufacturing cost, as Figure 2 shown, preferably, the alignment clamp 121 adopts a block structure. Of course, in order to achieve multi-point clamping on the entire side of the coil 600; correspondingly, the number of coil side fixtures 120 is multiple groups and is evenly distributed along the length direction of the mounting plate 110.

[0049] Furthermore, in order to adjust the clamping distance of the coil side fixture 120 to be suitable for coils 600 of different widths; correspondingly, the two alignment clamps 121 can be arranged on the mounting plate 110 to move towards or away from each other. This design enables the coil side fixture 120 to adjust its clamping distance according to the width of different coils 600 to meet the side clamping requirements of coils 600 in different forms. Of course, the movement mode of the above two alignment clamps 121 can be realized through the structure of the fixture guide rail, which will not be elaborated here.

[0050] Specifically, as Figure 2 shown, the coil height direction fixture 130 includes:

[0051] A rotary pressing cylinder 131 provided on the mounting plate 110;

[0052] A pressing rod 132 connected to the output end of the rotary pressing cylinder 131 and used to press the top of the coil 600. In this solution, the coil height direction fixture 130 is designed in this way to be able to adjust its pressing height according to the height of different coils 600 to meet the pressing requirements of coils 600 of different heights. This design has the characteristics of simple operation and good fixture versatility. Similarly, in order to achieve multi-point pressing on the top of the coil 600; correspondingly, the number of coil height direction fixtures 130 is also multiple groups and is evenly distributed along the length direction of the mounting plate 110.

[0053] In this solution, as Figure 3 shown, the coil nose fixture 140 includes:

[0054] A blocking fixture 141 used to be arranged at the end of the mounting plate 110 close to the laser device and cooperate with the outer side of the nose 620; based on this structure, this solution not only facilitates the blocking and positioning of the outer side of the nose 620, but also helps to accurately position different insulation removal lengths; of course, in order to avoid assembly interference between the blocking fixture 141 and the lead head 610; correspondingly, the blocking fixture 141 is provided with a mounting hole for cooperating with the lead head 610 of the coil 600;

[0055] A pin 142 disposed on the mounting plate 110 for clamping the inner side of the nose portion 620. Specifically, in this solution, the blocking fixture 141 is first used to achieve the blocking and positioning of the outer side of the nose portion 620. On this basis, the pin 142 is used to achieve the clamping and fixing of the inner side of the nose portion 620, that is, the clamping and fixing of the inner and outer sides of the nose portion 620 is achieved to prevent the lead head 610 of the coil 600 from moving, thereby ensuring the stability of the insulation removal operation of the lead head 610.

[0056] Further, in order to clamp different thicknesses (different number of turns) of the nose portion 620, it is required that the pin 142 can move relative to the blocking fixture 141 along the center line of the coil 600, so as to facilitate the adjustment of the clamping distance between the two to meet the clamping requirements of the nose portion 620 with different thicknesses; correspondingly, as Figure 3 shown, the pin 142 is movably disposed on the mounting plate 110 along the center line of the coil side fixture 120.

[0057] In this solution, in order to achieve the clamping and rotation of the coil 600 to meet the requirement of the laser device for removing the insulation on each surface of the lead head 610 of the coil 600, it is required that the first station fixing device 100 can rotate a certain angle so that each surface of the lead head 610 is in the focal plane of the laser device to achieve the effect of removing all the insulation of the lead head 610; correspondingly, as Figure 2 shown, the first station fixing device 100 further includes:

[0058] A fixed seat; the mounting plate 110 is rotatably disposed on the top of the fixed seat in the horizontal direction;

[0059] A mounting plate driving mechanism 800 disposed on the fixed seat for driving the mounting plate 110 to rotate.

[0060] To further optimize the above technical solution, as Figure 1 shown, the multi-station laser insulation removal fixing device provided by the embodiment of the present invention further includes: a second station fixing device 200; the structure of the second station fixing device 200 is the same as that of the first station fixing device 100;

[0061] A turntable 300; the first station fixing device 100 and the second station fixing device 200 are arranged in parallel and in opposite directions on the turntable 300, and are equally distributed on both sides of the center of the turntable 300; it should be noted that, Figure 1 the turntable 300 shown in

[0062] A turntable driving mechanism for driving the turntable 300 to rotate 180 degrees. This solution is designed in this way to facilitate the realization of a freely switchable dual-station working mode. Specifically, one of the first-station fixing device 100 and the second-station fixing device 200 can be used as the fixing device for the insulation removal station, and the other as the fixing device for the loading and unloading station. Then, through rotation, their free conversion is realized. In this way, it helps to achieve the continuous operation of the coil 600, thereby greatly improving the operation efficiency of the coil 600.

[0063] Further, to facilitate the rotation of the turntable 300 by 180 degrees, so that the first-station fixing device 100 and the second-station fixing device 200 can be respectively and sequentially switched between the laser insulation removal station and the loading and unloading station. Specifically, as Figure 1 shown, the turntable driving mechanism includes: a cam divider 410 and a driving motor;

[0064] The input end of the cam divider 410 is connected to the output end of the driving motor, and the output end is connected to the bottom of the turntable 300. In this solution, the turntable driving mechanism is designed in this way, having the characteristics of simple structure, stable rotation and long service life.

[0065] Still further, as Figure 1 shown, the multi-station laser insulation removal fixing device provided by the embodiment of the present invention further includes:

[0066] A guide rail 500 provided on the turntable 300; both the first-station fixing device 100 and the second-station fixing device 200 can move along the guide rail 500;

[0067] A first driving mechanism for driving the first-station fixing device 100 to move along the guide rail 500;

[0068] A second driving mechanism for driving the second-station fixing device 200 to move along the guide rail 500. In this solution, the guide rail 500 is a double-guide rail structure and is equidistantly distributed on both sides of the center of the turntable 300. Among them, the first-station fixing device 100 and the second-station fixing device 200 are respectively located on both sides of the guide rail 500; this solution is designed in this way. On the one hand, it is convenient to move the fixing device of the loading and unloading station to the outer edge of the turntable 300, thus facilitating the loading and unloading of the operator. On the other hand, it is convenient to move the fixing device of the insulation removal station towards the center of the turntable 300 so that the coil is close to the laser device, thereby facilitating the insulation removal operation of the laser device.

[0069] The following further introduces this solution in combination with specific embodiments:

[0070] In order to improve the insulation removal method of the coil, a CO2 laser device is used to remove the insulation of the coil lead head. In order to reduce the labor intensity of the operator, the fixture provided by the present invention is used to effectively fix the coil; at the same time, in order to improve the operation efficiency, a double-station is also adopted to facilitate simultaneous work.
