[0079] Please refer to Figure 8 As shown, a scale 813 is installed on the top of the body 1, and an electromagnet 814 is installed on the top of the scale 813. The scale 813 is made of iron material, and the left end of the scale 813 is located on the same vertical plane as the middle of the front side of the box 102.

[0080] It can be understood by those skilled in the art that the output end of the fifth stepping motor 804 drives the fifth lead screw 802 to rotate, so that the L-shaped plate 805 slides left and right along the fifth guide rod 803, thereby changing the position of the L-shaped plate 805; the output end of the second transmission motor 812 drives the driving gear 808 to rotate, so that the rotating circle 809 rotates, driving all the driven gears 807 to rotate synchronously, and then all the tooth plates 810 slide synchronously toward the center position of the mounting plate 806, so that all the clamping blocks 811 also move synchronously toward the center position of the mounting plate 806;

[0081] It is worth mentioning here that the clamping block 811 and the rotating circle 809 are offset, that is, the height of the clamping block 811 is higher than the rotating circle 809, so that the rotating circle 809 will not affect the movement of the clamping block 811; in addition, the mounting plate 806 is designed so that when the refrigerant hose passes through the through hole 103 on the right side of the box body 102, it will enter the interior of the mounting plate 806, and all the clamping blocks 811 will move toward the center of the mounting plate 806 to cover the outer surface of the refrigerant hose, and through this clamping method, during the subsequent coating process, the refrigerant hose is always located inside the mounting plate 806 and will not fall off.

[0082] Working principle and use process of this device: In order to clearly express the working principle of the present invention, we use Figure 1For the sake of perspective, in real life, the refrigerant hose of the air conditioner is very easy to bend. In the present invention, the refrigerant hose is bundled together with two sets of cable ties 202 to form a refrigerant hose roll 201. The purpose of this is that when the robot arm 3 grabs it and places it on the placement table 101, it will not become loose, thereby ensuring the continuity of the robot arm 3 feeding the material. In addition, by installing a counterweight block 203 inside the initial end of the refrigerant hose roll 201, the purpose of this is that this end of the refrigerant hose roll 201 will remain in a vertical state (such as Figure 1 shown);

[0083] First, the output end of the driving motor 511 drives the rotating rod 510 to rotate to a horizontal position, thereby driving the two groups of clamping plates 516 to rotate to a horizontal position, and the two groups of clamping plates 516 reach the position of the counterweight block 203 through the cooperation of the output end of the second stepper motor 504 and the output end of the third stepper motor 508, and the output end of the servo motor 515 drives the screw rod 513 to rotate, so that the two groups of clamping plates 516 are close to each other, clamping the initial end of the refrigerant hose roll 201, and then the output end of the driving motor 511 drives the rotating rod 510 to rotate to a vertical position, thereby driving the two groups of clamping plates 516 to rotate to a vertical position, so that the initial end of the refrigerant hose roll 201 that was originally in a vertical state becomes a horizontal state;

[0084] The two groups of cable ties 202 on the refrigerant hose roll 201 are in relative positions, and when the robot arm 3 puts down the refrigerant hose roll 201 on the placement table 101, the positions of the two groups of cable ties 202 are located directly below the lifting member 407. Through the cooperation of the output end of the first stepper motor 404 and the output end of the electric push rod 406, the positions of the two groups of cutters 409 are respectively adapted to the positions of the two groups of cable ties 202, and then the output end of the cylinder 416 is extended to drive the movable block 414 to move, so that the cutters 409 on both sides are close to each other, and the two groups of cable ties 202 are cut off in turn;

[0085] Then, the second screw rod 502 is driven to rotate by the output end of the second stepper motor 504, so that the two sets of clamping plates 516 move to the right, thereby extending the initial end of the refrigerant hose roll 201 into the interior of the box body 102, and then the initial end of the refrigerant hose roll 201 can be passed through the through hole 103 on the right side of the box body 102 through the cooperation of the output end of the fourth stepper motor 603 and the output end of the electric lifting rod 605. In the present invention, the process of sending the refrigerant hose out of the box body 102 is always performed by the second tube drawing assembly 6;

[0086] The refrigerant hose located in the box 102 drives the first gear 702 to rotate at the output end of the first transmission motor 703, and drives the first nozzle 707 and the second nozzle 708 to rotate. The first nozzle 707 is connected to the external anti-corrosion paint to coat the surface of the refrigerant hose, and a drying lamp (not shown in the figure) is also provided on the rotating gear ring 706 to quickly heat dry the paint sprayed on the surface of the refrigerant hose;

[0087] The above-mentioned whole process is to explain the continuous coating of the refrigerant hose. It is worth mentioning that the present invention has another feature. When the air conditioner is installed in real life, the required length of the refrigerant hose is within several threshold ranges, so the refrigerant hose needs to be cut later. The present invention can mark the cutting position to facilitate the subsequent cutting process. The specific steps are as follows:

[0088] According to actual needs, the position of the electromagnet 814 is adjusted. When the electromagnet 814 is energized, it will be adsorbed on the scale 813. When the L-shaped plate 805 moves to contact the electromagnet 814, the L-shaped plate 805 will stop moving, and the left end of the scale 813 is located on the same vertical plane as the middle of the front side of the box 102, that is, it is also located on the same vertical plane as the middle of the second nozzle 708.

[0089] When the initial end of the refrigerant hose roll 201 extends out of the box body 102, it will enter the interior of the mounting plate 806, and the output end of the second transmission motor 812 drives the driving gear 808 to rotate, so that all the clamping blocks 811 move synchronously toward the center of the mounting plate 806 to clamp the initial end of the refrigerant hose roll 201, and then the output end of the fifth stepper motor 804 drives the fifth screw rod 802 to rotate, so that the L-shaped plate 805 moves to the right and contacts the electromagnet 814, and then cooperates with the second pulling tube assembly 6, so that the refrigerant hose is in a straightened state, and then under the action of the output end of the first transmission motor 703, the second nozzle 708 sprays a brightly colored paint on the refrigerant hose to mark the later cutting part;

[0090] After the first mark is applied, the refrigerant hose is always located inside the mounting plate 806. Under the push of the second tube pulling assembly 6, the first mark is located inside the mounting plate 806. The clamping block 811 clamps the first mark, and then repeats the above steps to complete the second mark application. Similarly, all marks are applied on the refrigerant hose roll 201. The whole process is automated to meet the needs of the staff.

[0091] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
