Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0041] The wire outer coating removal machine disclosed in the present invention is described below in conjunction with the accompanying drawings. It can be used to remove paint layers, coating layers, insulating coating rubber, casings, etc. on the surfaces of various wires. In this embodiment, the paint removal of motor winding flat copper wire is used as an example for description. The motor winding flat copper wire has four sides that need to be painted, as shown in the attached figure. Figure 1 As shown, the wire outer coating removal machine includes

[0042] The wire pressing assembly 1 comprises an upper module 11 and a lower module 12, one of which is connected to a lifting mechanism 13 for driving the upper module 11 to move up and down relative to the other module;

[0043] The removal segment clamping assembly 2 is located at the rear side of the wire pressing assembly 1 (in this solution, the position where the wire passes first is the front, and the position where the wire passes later is the rear), and has a structure for clamping the removal segment;

[0044] The moving mechanism 3 is a structure that is connected to the removal section clamping assembly 2 and drives the removal section clamping assembly 2 to move back and forth linearly relative to the wire pressing assembly 2.

[0045] The wire clamping assembly 1 fixes the area on the wire where the outer coating does not need to be removed through the upper module 11 and the lower module 12, so as to facilitate the subsequent removal of the area where the coating needs to be removed by the clamping assembly 2 through a scraper.

[0046] As attached Figure 1 As shown, the position of the upper module 11 is fixed, and the upper module 11 is detachably plugged into the slot 171 of the upper mold fixing plate 17, and the upper module 11 has a portion 113 protruding from the slot 171, so as to facilitate the plugging and unplugging operation of the upper module 11. The upper module 11 is fixed to the upper mold fixing plate 17 by a quick lock handle 16 located on the side of the upper mold fixing plate 17, so that the upper mold can be easily replaced to adapt to different wires.

[0047] As attached Figure 2 , Attachment Figure 3 As shown, in order to ensure accurate positioning of the upper module 11 and the lower module, a positioning groove 112 is provided at the center of the bottom surface of the upper module. The top of the lower module is provided with a positioning boss 123 which is directly opposite to the positioning groove 112. A rectangular limiting notch 121 is formed on the top of the positioning boss 123. The size of the notch 121 decreases from the inlet end to the outlet end. The depth of the limiting notch 121 can be slightly smaller than the thickness and width of the motor winding flat copper wire. Limiting grooves 122 are respectively formed on both sides of the positioning boss 123 on the lower module 12. A guide pin 14 is arranged in the limiting groove 122. The outer periphery of the guide pin 14 is sleeved with a spring 15 extending to the surface of the lower module. One end of the spring is fixed to the bottom of the limiting groove 122, and the other end of the spring abuts against the bottom of the lower limiting groove 111 formed on the upper module 11 corresponding to the position of the guide pin and the spring when the upper module 11 and the lower module 12 are pressed together, thereby playing a buffering role to avoid deformation and damage of the transition of the motor winding flat copper wire caused by a large impact force when the upper module 11 and the lower module 12 are pressed together.

[0048] As attached Figure 1 As shown, the bottom of the lower module 12 is connected to the lifting mechanism 13 that drives it to rise and fall. The lifting mechanism 13 is preferably a lifting cylinder. The upper mold fixing plate 17 is arranged on two support plates 18 located on both sides of the lifting cylinder.

[0049] As attached Figure 1 , Attachment Figure 4As shown, the removal section clamping assembly 2 is used to clamp the two opposite sides of the part that needs to be painted by a pair of scrapers 26 thereon, and when the moving mechanism 3 drives the entire removal section clamping assembly 2 to move backward, the paint layer is completely hung out backward from the contact point between the scraper and the wire. The removal section clamping assembly 2 specifically includes a vertical plate 21, and a driving device 22 is provided on the rear side of the vertical plate 21. The driving device 22 is preferably a clamping cylinder, and the piston rod of the clamping cylinder passes through the vertical plate 21 and is connected to one end (lower end) of a transmission plate 23 on the front side of the vertical plate 21, and the other end (upper end) of the transmission plate 23 is pivotally connected to the pivot connection seat at the upper end of the vertical plate 21. A connecting plate 29 can be twistedly arranged at the center of the movable plate 23 relative to the movable plate 23, and the connecting plate 29 can be slidably mounted on a fixed shaft 210 vertically arranged on the front side of the vertical plate 21. The connecting plate 29 is provided with connecting seats 220 on the left and right sides of the fixed shaft 210, each of which is pivotally connected to one end of a transmission rod 24, and the other end of each transmission rod 24 is pivotally connected to one end of a swing arm 25, and the other end of the swing arm 25 is provided with a scraper 26, and the middle part of each swing arm 25 is pivotally connected to a fixed support block 27, and the transmission rod 24, swing arm 25 and scraper 26 on one side are symmetrically arranged with the transmission rod 24, swing arm 25 and scraper 26 on the other side. In addition, the spacing between the two scrapers 26 corresponds to the position of the notch 121 on the lower module 12.

[0050] Thus, when the piston rod of the driving device 22 is extended, the distance between the two scrapers 26 can be driven to decrease through the above structure, thereby clamping the flat copper wire of the motor winding located between them; when the piston rod of the driving device 22 is retracted, the distance between the two scrapers is enlarged, thereby releasing the material.

[0051] In addition, in order to effectively meet the requirements of different removal lengths, such as Figure 5 As shown, a removal length adjustment block 28 located between the two scrapers 26 is arranged on the support block 27 and can be adjusted in position. The specific adjustment is achieved through the following structure, that is, the removal length adjustment block 28 is L-shaped, and a waist-shaped hole 281 is formed on its cross bar. A connecting groove is arranged on the top of the support block 27. The removal length adjustment block 28 is connected to the support block by a bolt passing through the waist-shaped hole and screwed to the connecting groove. The corresponding position of the waist-shaped hole and the connecting groove can be adjusted to adjust the position of the removal length adjustment block 28, thereby adjusting the distance between it and the scraper 26 to achieve the adjustment of the removal length.

[0052] At the same time, if attached Figure 5As shown, a workpiece limiting groove 282 is formed on the removal length adjustment block 28, and the workpiece limiting groove 282 is aligned with the position of the notch 121. When the workpiece passes through the notch 121 and passes through two scrapers, it extends into the workpiece limiting groove 281, thereby limiting the length to be removed; and a sensor is provided on the front side of the removal length adjustment block 28 to determine whether there is a motor winding flat copper wire entering the removal length adjustment block 28.

[0053] Furthermore, in order to meet the different thicknesses of the paint layer, coating layer or outer covering layer of different wires, it is necessary to make the distance between the blades of the two scrapers 26 adjustable to meet the different removal depth requirements. Figure 1 , Attachment Figure 6 , Attachment Figure 7 As shown, a removal depth adjustment mechanism 4 is provided on the front side of the vertical plate 21, and the removal depth adjustment mechanism 4 includes a bracket 42 fixed on the vertical plate 21, and the bracket 42 is approximately a gantry. A clamping shaft is telescopically provided on the bracket 42, and the clamping shaft 22 abuts against the piston rod of the driving device 22 (clamping cylinder) when it is extended, thereby limiting the extension length of the piston rod, and then limiting the rotation distance of the transmission plate 23, and finally limiting the distance between the cutting edges of the two scrapers 26 to achieve depth control.

[0054] Among them, as attached Figure 6 , Attachment Figure 7 As shown, the clamping shaft 41 is limited in the limiting hole 421 of the bracket 42, and its length is greater than the limiting hole 421. A spring 45 is sleeved on the outer periphery of the clamping shaft 41, one end of the spring 45 abuts on the limiting step of the clamping shaft 41, and the other end abuts on the limiting step of the limiting hole 421. The inner end of the clamping shaft 41 is an inclined surface and abuts against the inclined surface of a wedge block 43. The wedge block 43 is slidably arranged in the sliding groove 422 on the bracket 42, and is connected to a micrometer 44 that drives it. The wedge block 43 is adjusted by the micrometer 44, so that the clamping shaft 41 can be driven to extend or retract under the reaction force of the spring 45.

[0055] As attached Figure 1 As shown, the moving mechanism 3 includes a base plate 31, on which the vertical plate 21 of the removal segment clamping assembly 2 is arranged. The base plate 31 is slidably arranged on a guide rail 32 and connected to a cylinder 33 that drives it to move. The cylinder shaft of the cylinder 33 is in an extended state under normal circumstances.

[0056] In addition, since the motor winding flat copper wire has four surfaces to be depainted, and their lengths and widths are different, the depainting needs to be done in two steps. In addition, in order to avoid repeatedly adjusting the distance between the two scrapers to adapt to the requirements of different sizes, as shown in the attached Figure 1As shown, the wire outer coating removal machine includes two groups of the wire pressing components 1, the removal section clamping components 2 and the moving mechanism 3, and the extension direction of the blade edges of the scrapers 26 of the two removal section clamping components 2 is vertical, that is, the blade edges of the two scrapers 26 of one removal section clamping component 2 extend in the horizontal direction, and the blade edges of the two scrapers 26 of the other removal section clamping component 2 extend in the vertical direction. Therefore, when depainting the flat copper wire of the same type of motor set, the paint on both sides can be removed on one removal section clamping component 2, and then the paint on the other two sides can be removed on the other removal section clamping component 2. At this time, there is no need to repeatedly adjust the scraper 26.

[0057] Furthermore, in order to prevent the paint layer or coating from adhering to the cutting edge of the scraper and affecting the reliability of subsequent paint removal of the scraper, an air nozzle (not shown in the figure) for blowing air toward the cutting edge of the scraper is provided on the scraper side of the removal section clamping assembly 2, and the air nozzle is connected to an air supply device (not shown in the figure). The air nozzle, the air supply device and their connection are all prior art and will not be described in detail here.

[0058] At the same time, the entire above-mentioned mechanism is arranged on a base, and, as shown in the attached Figure 8 As shown, a protective plate 5, an operation panel 6, an electrical and start-up control cabinet 7 (which may be a PLC control) and the like are also provided on the periphery of the wire pressing assembly 1, the removing segment clamping assembly 2 and the moving mechanism 3, which are all prior arts and will not be described in detail. A loading port 8 corresponding to the gap between the upper module and the lower module of the wire pressing assembly 1 is provided on the front protective plate.

[0059] The working process of the above-mentioned wire outer coating removal machine will be described in detail below, which is as follows:

[0060] S1, first adjust the removal length adjustment block 28 to the set removal length position and adjust the scraper 26 to the set removal depth through the removal depth adjustment mechanism 4 according to the required removal length and depth requirements; when adjusting the depth, the wedge block is driven by adjusting the knob of the micrometer, and then the wedge block drives the clamping shaft 41.

[0061] S2, then, the flat copper wire of the motor winding is extended from the loading port 8 on one side, passes between the upper module and the lower module and goes deep into the limit groove of the removal length adjustment block 23. At this time, the sensor senses the workpiece, and the piston rod of the lifting cylinder extends to drive the lower module to move toward the upper module. After the piston rod is extended into place, the upper module and the lower module clamp and fix the flat copper wire of the motor winding.

[0062] S3, at this time, the cylinder shaft of the clamping cylinder of the removal section clamping assembly 2 extends out, and the lower end of the transmission plate 22 rotates around its upper end, thereby driving the connecting plate 29 to move along the fixed axis 210 toward the wire clamping assembly 1, and the connecting plate 29 drives the two transmission rods 24 to move forward at one end connected to the connecting plate 29, so that the other ends of the two transmission rods 24 push the swing arm 25 to rotate around the connection axis with the support block 27, and the distance between the two scrapers 26 is reduced, thereby clamping the flat copper wire of the motor winding passing through the scraper 26.

[0063] S4, then, the piston rod of the cylinder 33 of the moving mechanism 3 retracts, thereby driving the base plate to move toward the rear side (away from the wire clamping assembly 1), and the base plate drives the removal section clamping assembly 2 to move as a whole away from the wire clamping assembly 1, so that the two scrapers 26 are opened from their clamping position to remove the paint at the rear end.

[0064] S5, after the paint removal on both sides is completed, each cylinder is reset, the motor winding flat copper wire is pulled out from the feed port, inserted from the feed port on the other side, and then steps S2-S4 are repeated to complete the paint removal on the other two sides.

[0065] There are many implementation methods of the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
