People familiar with this technology can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. It should be understood that these embodiments are only to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field can make some non-essential improvements and adjustments to the present invention based on the content of the above invention; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figures 1-10 A dipping device for a wound resistor includes a main body 1, a dipping tank 2, a rack 3, a transmission chain system 4 and a conveyor belt 7. A longitudinal partition 6 is provided in the middle of the main body 1, which divides the interior of the main body 1 into a drying area 11 and a dipping area 12. An operation area opening 8 is provided on the main body 1 near the dipping area 12. Two dipping tanks 2 are spaced apart from each other in the dipping area 12. A conveyor belt 7 is provided at the bottom of the dipping area 12. Several staggered partitions 5 are provided in the drying area 11, and there is a distance between the partitions 5 and the main body 1. Several driving wheels 13 are provided in the dipping area 12 and the drying area 11, one of the driving wheels 13 is connected to a driving motor, and a transmission chain system 4 is wound around the several driving wheels 13. Several clamping mechanisms 48 and gear assemblies 46 are provided in the transmission chain system 4. The gear assembly 46 can be used to adjust the rotation angle of the clamping mechanism 48. The transmission chain system 4 forms a closed loop around several drive wheels 13, and the transmission chain system 4 sequentially passes through the dipping tank 2 in the dipping area 12, the partition plate 5 in the drying area 11, and the conveyor belt 7. Racks 3 are provided at the two dipping tanks 2, and the racks 3 can be used in conjunction with the gear assembly 46 of the transmission chain system 4; racks 3 are provided at both the dipping tank 2 and the conveyor belt 7.

[0042] In addition, an exhaust port 9 is provided at the top of the dipping area 12 and the drying area 11, and an air inlet 10 is provided at the bottom of the drying area 11. The travel of the transmission chain system 4 in the drying area 11 is serpentine. The serpentine structure can increase the travel of the transmission chain system 4 in the drying area 11, thereby improving the drying time of the wound resistor.

[0043] During use, the worker inserts the winding resistor into the clamping mechanism 48 of the transmission chain system 4 at the opening 8 of the operating area, and then the clamping mechanism 48 clamps the winding resistor. When the clamped winding resistor moves with the transmission chain system 4 to the dipping tank 2, the rack 3 and the transmission chain system 4 work together to rotate the winding resistor to be immersed in the dipping tank 2 and move in the dipping tank 2. When it is about to leave the dipping tank 2, the rack 3 and the transmission chain system 4 act again to rotate the winding resistor and leave the dipping tank 2. Then, it is guided by the driving wheel 13 and the transmission chain system 4, and cooperates with the rack 3 to allow the winding resistor to enter the dipping tank 2 again. The winding resistor is immersed in the dipping tank 2 and moves. As the transmission chain system 4 leaves the dipping tank 2 and enters the drying area 11, the wound resistor performs a serpentine motion around several partition plates 5 in the drying area 11, and finally enters the dipping area 12 from the drying area 11. When entering above the conveyor belt 7, the clamping mechanism 48 is loosened, so that the wound resistor falls off from the transmission chain system 4, completing the dipping work. A rack 3 is also provided above the conveyor belt 7. The rack 3 can rotate the clamping mechanism 48 of the transmission chain system 4, so that the wound resistor that has not fallen off falls off; when the clamping mechanism 48 leaves above the conveyor belt 7, it begins to close. When it runs to the bottom of the opening 8 of the operating area, the clamping mechanism 48 opens again, making it convenient for workers to put in new wound resistors to be dipped.

[0044] See Figure 2-Figure 6 The transmission chain system 4 is provided with a guide slide 41, a chain 42, a push-pull rod 43, a guide pull rod 44, a mounting frame 45, a gear assembly 46, a mounting plate 47, a clamping mechanism 48 and a linkage rod 49. Two groups of chains 42 are arranged side by side, and each group of chains 42 is driven by the driving wheel 13. The outer sides of the two chains 42 arranged side by side are each provided with a guide slide 41, and a mounting frame 45 is installed on the inner chain plate of the chain 42. A circular through hole is provided on the pin shaft of the chain 42 near the mounting frame 45, and the circular through hole can be passed through by the push-pull rod 43. The push-pull rod 43 is connected to the upper part of the guide pull rod 44. The guide pull rod 44 is a T-shaped structure, and a guide slider 410 is provided at the end of the guide pull rod 44, and the guide slider 410 can slide in the guide slide 41.

[0045] The relative position between the guide rod 44 and the push-pull rod 33 can be adjusted to adjust the distance between two clamping mechanisms 48 in the same row.

[0046] A gear assembly 46 is provided on the side of the mounting frame 45 away from the inner chain plate. A mounting plate 47 is provided on the side of the gear assembly 46 away from the mounting frame 45. A clamping mechanism 48 is provided on the mounting plate 47. A linkage rod 49 is provided between two clamping mechanisms 48 in the same row. The two ends of the linkage rod 49 are respectively connected to the two clamping mechanisms 48. One of the clamping mechanisms 48 is provided with a guide block, and the linkage rod 49 can slide in the guide block. The end of the mounting frame 45 close to the inner chain plate is a hollow bracket 4501, which is connected to the hollow bracket 4501. It is connected to a rotating shaft frame 4502, which is provided with a rotating shaft 4503. The gear assembly 46 can rotate around the rotating shaft 4503. A ratchet is provided between the gear assembly 46 and the rotating shaft 4503, so the gear assembly 46 can only rotate in one direction; in addition, when the mounting frame 45 of different lengths is replaced, the distance between the two clamping mechanisms 48 arranged in the same row will change. At this time, the relative position of the linkage rod 49 will also change accordingly. The linkage rod 49 can ensure that the two clamping mechanisms 48 in the same row rotate synchronously.

[0047] In this embodiment, refer to 7 , the gear assembly 46 includes a ring gear 4601 and a ratchet assembly 4602. One end of the ratchet assembly 4602 is fixedly connected to the rotating shaft 4503. The end of the ring gear 4601 away from the mounting frame 45 is fixedly connected to the mounting plate 47. The ring gear 4601 can rotate around the rotating shaft 4503. A plurality of balls that can only move in one direction are provided between the ring gear 4601 and the ratchet assembly 4602. A ball slide is provided on the inner side wall of the ring gear 4601.

[0048] During use, when the ring gear 4601 encounters the rack 3 during movement, it will cause the ring gear 4601 to rotate. The rotation of the ring gear 4601 will drive the mounting plate 47 to rotate, but the rotation of the ring gear 4601 will not cause the ratchet assembly 4602 to rotate, thereby ensuring the stability of the operation of the entire transmission chain system 4.

[0049] In this embodiment, the structure of the rack 3 can be continuous or discontinuous, see Figure 8 In this embodiment, the rack 3 adopts a discontinuous structure, and the intermittent spacing is set according to the tooth pitch, so as to accurately adjust the rotation angle of the gear assembly 46.

[0050] See Figure 3-Figure 6The clamping mechanism 48 includes a support frame 4801, a rotating shaft mounting block 4802, a clamping claw 4803, a pushing slider 4804, a slip ring 4806 and a tension spring 4808. The support frame 4801 is connected to the mounting plate 47, and the support frame 4801 is also fixedly connected to the rotating shaft mounting block 4802. The rotating shaft mounting block 4802 is rotatably connected to a rotating arm 4805 through a detachable pin shaft. The inner side of the rotating arm 4805 is provided with a pushing slider 4804, and the pushing slider 4804 is connected to the push-pull rod 43. The structure of the rotating arm 4805 is similar to the structural principle of the elbow pliers or the right-angle pliers. The rotating arm 4805 can be opened and closed. The rotating arm 4805 is used in conjunction with the clamping claw 4803. When the rotating arm 4805 moves inward, the clamping claw 4803 opens. Conversely, when the rotating arm 4805 moves outward, the clamping claw 4803 is closed. The clamping claw 4803 is used to clamp one leg of the wound resistor.

[0051] Two symmetrically arranged slip rings 4806 are provided on the pushing slider 4804, and the slip rings 4806 are respectively mounted on the two handles of the rotating arm 4805. Therefore, when the pushing slider 4804 moves toward the position close to the clamping jaw 4803, the slip ring 4806 will drive the rotating arm 4805 to open, thereby closing the clamping jaw 4803. When the pushing slider 4804 moves toward the mounting plate 47, the rotating arm 4805 will shrink and close inward, thereby opening the clamping jaw 4803.

[0052] In addition, a protrusion 4810 is provided on the clamping jaw 4803 for further clamping the wound resistor; a guide rod 4809 is provided on the rotating shaft mounting block 4802, and two limit blocks 4807 are provided on the pushing slider 4804 corresponding to the rotating shaft mounting block 4802. The guide rod 4809 can pass through the limit block 4807, and a tension spring 4808 is provided on the guide rod 4809 between the limit block 4807 and the rotating shaft mounting block 4802.

[0053] See Figure 9 When in use, a rubber sleeve is provided on the outside of the clamping mechanism 48 to prevent the coating material from splashing into the interior of the mechanism and affecting the operation of the entire mechanism.

[0054] The guide slide 41 is extended outward near the conveyor belt 7 and the operation area opening 8. Figure 2As shown in the guide slide 41 structure, when the guide slider 410 runs here, the guide slider 410 moves outward to drive the guide pull rod 44 to move outward, the guide pull rod 44 drives the push-pull rod 43 to move outward, and the push-pull rod 43 drives the push slider 4804 to move outward. The process of pushing the slider 4804 will cause the rotating arm 4805 to retract inward, thereby causing the clamping claw 4803 to open. The opening of the clamping claw 4803 will cause the winding resistor to fall. In order to ensure that the winding resistor falls normally, the clamping mechanism 48 above the conveyor belt 7 is affected by the rack 3 and will be in a downward position. state, therefore, when the clamping jaws 4803 are opened, the wound resistor will fall under the action of gravity; similarly, the clamping jaws 4803 at the opening 8 of the operating area are set to be in an upward state, so that when the worker inserts the wound resistor into the opened clamping jaws 4803, the wound resistor will not fall. After the winding resistor is inserted, the guide slide 41 contracts inward, and at this time it will drive the movement of the slider 4804 again, so that the rotating arm 4805 is opened, and then the clamping jaws 4803 clamp the wound resistor. During this process, the clamping mechanism 48 is in an upward movement process to ensure that the wound resistor will not fall.

[0055] Example 2

[0056] See Figure 10 , a dipping device for a wound resistor, including all the contents of embodiment body 1. In addition, the clamping jaw 4803 is provided with a clamping groove 4811, and the bottom of the clamping groove 4811 is provided with a plurality of grooves 4812.

[0057] The technical effect achieved by this embodiment is that the arrangement of the clamping groove 4811 enables Figure 11 The wire-wound resistor shown can also be well fixed. In addition, the shape of the clamp 4803 can be designed according to different wire-wound resistors. The clamp 4803 can also be installed in a detachable manner, so as to facilitate the adaptation of different types of wire-wound resistors and facilitate the modification of equipment.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
