[0001] The utility model belongs to the technical field of wire processing, and particularly relates to a glue coating device for wire parallel connection. Background Art

[0002] After the power wire is processed, wire parallel connection may be required according to different application requirements. When performing wire parallel connection, glue needs to be applied to both sides of the wire, and then the wires are adhered. The utility model patent with the publication number CN209849178U discloses a wire bonding device, which applies glue to the wire through a glue coating roller, and then removes the glue at the bottom of the wire through a glue removing roller covered with sponge or wool felt, and then performs subsequent parallel connection and adhesion. When removing the glue adhered to the bottom of the wire by this device, since the sponge or wool felt will reach a saturated state after adsorbing a certain amount of glue, it is necessary to frequently replace the sponge or wool felt, so improvements are necessary. Content of the Utility Model

[0003] To solve the above-mentioned defects of the prior art, the present application provides a glue coating device for wire parallel connection, which can scrape the glue at the bottom of the wire through a scraper. Compared with adsorbing the glue at the bottom of the wire by sponge or wool felt, it is not necessary to frequently replace the sponge or wool felt.

Detailed implementation manners

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] An embodiment of the present application provides a glue - applying device for wire parallel connection, as Figures 1-5 shown, which includes a glue pool 1, a glue - scraping plate 5 and a pair of feeding rollers 3.

[0026] Specifically, a glue - applying roller 2 is rotatably connected in the glue pool 1. The glue - applying roller 2 is connected to a rotating mechanism for driving the glue - applying roller 2 to rotate. The axial direction of the glue - applying roller 2 is parallel to the length direction of the glue pool 1. A plurality of first annular grooves 201 for accommodating the electric wires 4 are arranged axially on the glue - applying roller 2 in an array. The top of the first annular groove 201 protrudes above the top of the glue pool 1. A pair of feeding rollers 3 rotating in opposite directions are arranged at intervals on one side of the glue pool 1 for conveying the electric wires 4. The glue - scraping plate 5 is arranged between the feeding rollers 3 and the glue pool 1. The included angle between the side of the glue - scraping plate 5 facing the glue pool 1 and one side of the glue pool 1 is less than 90 degrees. A plurality of arc - shaped grooves 501 corresponding to the first annular grooves 201 are opened at the top of the glue - scraping plate 5 for accommodating the electric wires 4 passing through the top of the first annular grooves 201.

[0027] During actual use, a plurality of the electric wires 4 in the electric wires 4 are respectively placed in the plurality of first annular grooves 201 of the glue - applying roller 2. Then, the front ends of the electric wires 4 are placed between the pair of feeding rollers 3, and the plurality of electric wires 4 are respectively located in the plurality of arc - shaped grooves 501 on the glue - scraping plate 5. Then, the rotating mechanism is controlled to drive the glue - applying roller 2 to rotate, so that the first annular grooves 201 adhere to glue, and thus the electric wires 4 passing through the first annular grooves 201 are coated with glue. At the same time, the pair of feeding rollers 3 are controlled to rotate in opposite directions to drive the electric wires 4 to move. During the movement of the electric wires 4, since the bottom of the electric wires 4 abuts against the arc - shaped grooves 501, the glue adhered to the bottom will be scraped off by the scraping plate, so that only the two sides of the electric wires 4 have glue for subsequent parallel connection and adhesion.

[0028] Specifically, the height of the arc-shaped groove 501 is less than the radius of the wire 4. When the wire 4 is located in the arc-shaped groove 501, the two sides of the wire 4 do not contact the arc-shaped groove 501, preventing the glue adhered to the two sides of the wire 4 from being scraped off and affecting the subsequent wire merging and adhesion.

[0029] Specifically, referring to Figure 4 , a plurality of second annular grooves 301 for accommodating the wire 4 are axially arranged in an array on one of the feeding rollers 3. When the wire 4 is being conveyed, the wire 4 can be limited to prevent it from shifting. More specifically, a pair of feeding rollers 3 are respectively rotatably connected between two pairs of fixing plates 302. A pair of feeding rollers 3 are respectively connected to the output shafts of two second driving motors 303. A pair of accommodating holes 304 are provided at the bottoms of the upper pair of fixing plates 302. A pair of guide rods 305 corresponding to the accommodating holes 304 are provided on each of the lower pair of fixing plates 302. The guide rods 305 are slidably connected in the corresponding accommodating holes 304, and springs 306 are sleeved on the guide rods 305. The two ends of the springs 306 are respectively connected to the upper fixing plate 302 and the lower fixing plate 302. By connecting the upper and lower fixing plates 302 with the springs 306, when a wire 4 with a larger diameter is placed between the pair of feeding rollers 3, the upper feeding roller 3 can move upward. Since the pulling force of the springs 306 will squeeze the wire 4, a frictional force is generated on the wire 4, so as to realize the conveyance of the wire 4 with a larger diameter.

[0030] Specifically, referring to Figure 1 、 Figure 3 , on the other side of the glue pool 1, a pair of guide rollers 7 are arranged at intervals. The pair of guide rollers 7 are arranged in an array along the width direction of the glue pool 1, and a plurality of third annular grooves 701 for accommodating the wire 4 are axially arranged on each of the pair of guide rollers 7. When applying glue, first pass the wire 4 through between the pair of guide rollers 7 from above and make the wire 4 located in the third annular grooves 701, and then wind the wire 4 upward to the top of the first annular groove 201 of the glue application roller 2, which can prevent the wire 4 from deflecting during conveyance and avoid the situation of the wire 4 being wound.

[0031] Preferably, referring to Figure 3 , the bottom of the glue scraping plate 5 is connected to one side of the glue pool 1. A plurality of diversion grooves 502 are provided inside the glue scraping plate 5. The plurality of diversion grooves 502 are respectively located below the plurality of arc-shaped grooves 501. A plurality of feed holes 101 are provided on one side of the glue pool 1. The plurality of feed holes 101 are respectively communicated with the plurality of diversion grooves 502. When the glue adhered to the bottom of the wire 4 is scraped off by the glue scraping plate 5, it will flow into the glue pool 1 through the diversion grooves 502 and the feed holes 101, and the glue can be reused.

[0032] Specifically, referring to Figure 1 、 Figure 2, the rotating mechanism includes a worm gear 601, a worm 602, and a first driving motor 6. The glue applicator roller 2 is rotatably connected to the glue pool 1 through a rotating shaft 202. One end of the rotating shaft 202 passes through the glue pool 1 and is connected to the worm gear 601. The worm 602 is meshed and connected below the worm gear 601. The output shaft of the first driving motor 6 is connected to the worm gear 601. Through the cooperation of the worm gear 601 and the worm 602, the rotation speed of the glue applicator roller 2 can be controlled at a relatively low speed to prevent the glue from being thrown out due to the too fast rotation speed of the glue applicator roller 2.

[0033] The above are only some embodiments listed in this application and are not used to limit this application.
