DETAILED DESCRIPTION

[0022] The technical scheme of the present application will be described clearly and completely in combination with specific embodiments. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments.

[0023] Embodiment: a heating film electric measuring device, like Figs. 1-3As shown, including a U-shaped plate 1, a pair of feeding box 2 and discharging box 3 fixedly connected to both ends of the U-shaped plate 1 respectively, a rotating shaft one 4 rotatably arranged in the U-shaped plate 1, a servo motor one 5 driving the rotating shaft one 4 to rotate, a pair of driving pulleys 6 fixed to the rotating shaft one 4, a pair of driven pulleys 7 rotatably arranged in the inner walls of both sides of the U-shaped plate 1 respectively, two belts 8 respectively sleeved on the two pairs of driving pulleys 6 and driven pulleys 7, a lifting plate one 9 liftingly arranged in the feeding box 2, a lifting assembly 10 driving the lifting plate to lift, a rotating shaft two 11 rotatably arranged in the U-shaped plate 1 and located between the belt 8 and the feeding box 2, a servo motor two 12 driving the rotating shaft two 11 to rotate, a turnover plate 13 one end of which is fixedly connected to the rotating shaft one 4 and located between the two belts 8 and turns over, a suction assembly 14 arranged on one side of the turnover plate 13 and capable of sucking the heating film in the feeding box 2, an ohmmeter 15 fixed to the side of the U-shaped plate 1, an air cylinder 16 vertically fixed to the inner bottom of the U-shaped plate 1 and located between the two belts 8, a lifting plate two 17 horizontally fixedly connected to the upper end of the piston rod of the air cylinder 16 and located between the two belts 8 and moves up and down, a red meter pen 18 and a black meter pen 19 vertically fixed to the top of the lifting plate two 17 and connected to the positive and negative electrodes of the ohmmeter 15;

[0024] The opening height of the feeding box 2 and the discharging box 3 is not more than the conveying height of the belt 8, when the turnover plate 13 is parallel to the feeding box 2, the suction assembly 14 on one side of the turnover plate 13 contacts and sucks the heating film, when the turnover plate 13 is parallel to the middle of the two belts 8, the heating film sucked by the suction assembly 14 is horizontally placed on the two belts 8; the driving pulley 6 and the driven pulley 7 are close to the discharging box 3 and the feeding box 2 respectively, and the turnover plate 13 is located between the two driven pulleys 7; the servo motor one 5 and the servo motor two 12 are fixed to the outer wall of one side of the U-shaped plate 1, both ends of the rotating shaft one 4 and the rotating shaft two 11 are rotatably arranged out of the two sides of the U-shaped plate 1 respectively, and one end of the rotating shaft one 4 and the rotating shaft two 11 arranged out of the side of the U-shaped plate 1 is connected to the output end of the servo motor one 5 and the servo motor two 12 respectively.

[0025] Furthermore, the lifting assembly 10 includes a square groove 10a opened on the outer wall of the loading box 2, a slide plate 10b that slides vertically in the square groove 10a, a pair of elongated holes 10c opened at the bottom of the square groove 10a and communicating with the inside of the loading box 2, a pair of connecting blocks 10d fixed to one side of the slide plate 10b and respectively passing through the two elongated holes 10c and connecting to the lifting plate 9, a screw 10e that is vertically rotatably set inside the square groove 10a and passes through the slide plate 10b, a nut 10f fixed to the bottom of the slide plate 10b and threadedly connected to the screw 10e, a small motor 10g fixed to the outer wall of the loading box 2 and whose output end rotates into the square groove 10a, a bevel gear 10h fixed to the lower end of the screw 10e, and a bevel gear 10i fixed to the output end of the small motor 10g and meshing with the bevel gear 10h. The square groove 10a is located on one side of the loading box 2 connected to the U-shaped plate 1, and the screw 10e is located vertically between the two elongated holes 10c.

[0026] By employing the aforementioned lifting assembly 10, when the lifting plate 9 needs to be raised or lowered, firstly, the small motor 10g drives the bevel gear 10i to rotate, causing the bevel gear 10i to mesh with the bevel gear 10h. Then, the bevel gear 10h drives the screw 10e to rotate, causing the threaded connecting nut 10f to slide the square groove 10a opposite to the slide plate 10b. Finally, the slide plate 10b drives the lifting plate 9 inside the feeding box 2 to rise or fall through the connecting block 10d, thereby ensuring that the uppermost heating film inside the feeding box 2 is flush with the opening of the feeding box 2, so that the adsorption assembly 14 can adsorb and carry it away.

[0027] Furthermore, the adsorption assembly 14 includes four suction cups 14a fixedly disposed on one side of the flipping plate 13, an air suction pipe 14b fixedly disposed on the other side of the flipping plate 13, an air suction channel 14c opened inside the flipping plate 13 and connecting the four suction cups 14a and the air suction pipe 14b, and an air suction pump 14d fixed to the bottom of the U-shaped plate 1 and connected to the air suction pipe 14b. The suction cups 14a are located on the side of the flipping plate 13 that faces the opening of the loading box 2, and the air suction pipe 14b is a flexible hose with a length that can adapt to the flipping movement of the flipping plate 13. By using the above-mentioned adsorption assembly 14, when the suction cups 14a contact the surface of the heating film, the air suction pump 14d will automatically work and extract the air inside the suction cups 14a through the air suction pipe 14b and the air suction channel 14c, thereby reducing the air pressure inside the suction cups 14a and firmly adsorbing the surface of the heating film, thus achieving the transfer effect of the heating film in conjunction with the flipping movement of the flipping plate 13.

[0028] Further, the top of the U-shaped plate 1 is horizontally fixedly provided with a top plate 20, and the baffle is located between the red watch pen 18 and the black watch pen 19. The top plate 20 is fixedly provided with a fixed positioning block 20a on the side close to the belt 8, which can position the upper surface of the heating film when the red watch pen 18 and the black watch pen 19 contact the positive and negative electrodes of the heating film. In addition to avoiding the heating film being lifted by the red watch pen 18 and the black watch pen 19, the contact between the positive and negative electrodes of the heating film and the red watch pen 18 and the black watch pen 19 is also stable.

[0029] Further, the inside of the U-shaped plate 1 is rotatably provided with a rotating shaft three 21, and the rotating shaft three 21 is rotatably provided at both ends of the U-shaped plate 1. The U-shaped plate 1 is fixedly provided with a small motor two 22 on one side, and the output end of the small motor two 22 is connected to one end of the rotating shaft three 21. The rotating shaft three 21 is horizontally located above the belt 8, and is fixedly provided with a pair of movable positioning plates 23 which can position the end of the heating film. The rotating shaft three 21 penetrates the fixed positioning block 20a, and the two movable plates on the rotating shaft three 21 are located on both sides of the fixed positioning block 20a. When the positive and negative electrodes of the heating film are aligned with the red watch pen 18 and the black watch pen 19, the movable positioning plate 23 will position the front end of the heating film in a vertical state, thereby avoiding the heating film being slightly moved forward under the influence of the belt 8 stopping suddenly, which causes the red watch pen 18 and the black watch pen 19 to be misaligned with the positive and negative electrodes of the heating film. After the heating film is tested, the small motor two 22 drives the rotating shaft three 21 to rotate, so that the movable positioning plate 23 connected to the rotating shaft three 21 is turned to a horizontal state parallel to the belt 8, so that the heating film can leave from below the fixed positioning plate.

[0030] Further, the end of the feeding box 2 away from the U-shaped plate 1 is provided with a gap one 2a, and the gap one 2a penetrates the top of the feeding box 2. The end of the discharging box 3 away from the U-shaped plate 1 is provided with a gap two 3a, and the gap two 3a penetrates the top of the discharging box 3. By using the above-mentioned gap one 2a and gap two 3a, it is convenient for the staff to put a bunch of heating films into the feeding box 2 or take them out of the discharging box 3.

[0031] Further, the top of the feeding box 2 is fixedly provided with a pair of right-angled triangular baffles one 2b, and the two baffles one 2b are flush with the two sides of the feeding box 2, respectively. The top of the discharging box 3 is fixedly provided with a pair of right-angled triangular baffles two 3b, and the two baffles two 3b are flush with the two sides of the discharging box 3, respectively. By using the above-mentioned baffles one 2b and baffles two 3b, the heating film can smoothly leave the feeding box 2 and smoothly enter the discharging box 3.

[0032] Further, a plurality of support rollers 1a are rotatably arranged on the inner walls of the two side edges of the U-shaped plate 1, and the support rollers 1a are located in the middle of the belt 8 and support the inside of the upper side of the belt 8. By using the above-mentioned support rollers 1a, the stability of the belt 8 conveying the heating film can be further improved.

[0033] Working principle of the embodiment:

[0034] When it is necessary to test the resistance value of the heating film, first, the heating film is stacked in the feeding box 2; then the lifting assembly 10 drives the lifting plate 9 to lift, so that the uppermost heating film is flush with the top opening of the feeding box 2; then the servo motor 2 drives the rotating shaft 2 to rotate, so that the turnover plate 13 connected to one end of the rotating shaft 2 is turned over; after the turnover plate 13 is parallel to the upper side of the feeding box 2, the suction assembly 14 automatically sucks the uppermost heating film of the feeding box 2; then the servo motor 2 drives the rotating shaft 2 to rotate in the opposite direction, so that the turnover plate 13 is turned over to the horizontal position between the two belts 8, and the heating film sucked by the suction assembly 14 is transferred from the feeding box 2 to the position above the two belts 8 under the driving of the turnover plate 13; then the suction assembly 14 stops working to release the suction of the heating film, and at the same time, the servo motor 1 drives the rotating shaft 1 to rotate, and drives the belt 8 to work through the driving pulley 6 and the driven pulley 7, so that the belt 8 conveying the heating film approaches the test position in the middle of the U-shaped plate 1; after the positive and negative electrodes of the heating film are aligned with the red and black pen 18 and 19 on the lifting plate 2, the servo motor 1 stops working, and the cylinder 16 drives the lifting plate 2 to approach the heating film, so that the pen head of the red and black pen 18 and 19 contacts the heating negative electrode, at this time, the resistance value of the heating film can be easily obtained by reading the display value on the ohmmeter 15; finally, after the heating film is tested, the servo motor 1 continues to work, so that the belt 8 conveying the heating film approaches the discharging box 3 and falls into the discharging box 3, thereby completing the electrical testing of the heating film. Compared with the traditional manual testing, the above-mentioned automatic testing process of the resistance value of the heating film not only has high efficiency and low labor cost, but also the belt 8 conveying the heating film is stable and safe, and is not easy to cause damage to the heating film, so the safety is better.
