[0026] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0027] See also Figures 1 to 4 The present invention is a resistor element screening, cleaning and drying integrated machine, comprising a feeding device 1, a vibrating device 2, a cleaning device 3 and a drying device 4 arranged in sequence along the conveying direction, the screening, cleaning and drying integrated machine further comprising a guide assembly 5, the guide assembly 5 passing through the vibrating device 2, the cleaning device 3 and the drying device 4;

[0028] The vibration device 2 includes an inner cylinder 21, an outer cylinder 22, a weight member 23, a first driving member 24, and an elastic member 25. The central axis of the inner cylinder 21 coincides with the central axis of the outer cylinder 22. The inner cylinder 21 and the outer cylinder 22 are spaced apart to form a receiving cavity. The weight member 23 is disposed in the receiving cavity and contacts the inner cylinder 21. The first driving member 24 is disposed in the outer cylinder 22 and drives the weight member 23 to swing.

[0029] The number of the elastic members 25 is at least three, and the three elastic members 25 are arranged in the accommodating cavity. The two ends of the elastic members 25 are connected to the inner tube 21 and the outer tube 22 respectively.

[0030] The central axis of the guide assembly 5 coincides with the central axis of the inner cylinder 21 , and the external resistance element slides along the guide assembly 5 .

[0031] Specifically, in this embodiment, the resistance element is an annular varistor, and the annular varistor to be cleaned from the outside is fed one by one by the feeding device 1. The feeding device 1 includes a vertical pipe and a bend. The inner diameter of the vertical pipe and the inner diameter of the bend are both larger than the radial specifications of the annular varistor. The bend is connected to the vertical pipe and the vibration device 2. The vibration device 2 includes an inner cylinder 21, an outer cylinder 22, a gravity member 23, a first driving member 24, an elastic member 25 and a guide assembly 5. A paddle and a paddle driving member are installed in the bend. The paddle driving member drives the paddle to rotate to control a single annular varistor to enter the guide assembly 5 of the vibration device 2 in sequence. Preferably, the radial specification of the inner cylinder 21 is 2 mm larger than the radial specification of the annular varistor. The external annular varistor is sleeved on the guide assembly 5. There are multiple elastic members 25, and multiple elastic members 25 are arranged around the outer wall of the inner cylinder 21. Each The two ends of the elastic member 25 are respectively connected to the inner cylinder 21 and the outer cylinder 22. The gravity member 23 is spherically placed above the inner cylinder 21. The first driving member 24 adopts a servo motor to drive the cam rotation structure to drive the gravity member 23 to swing with the central axis of the inner cylinder 21 as the central axis. During the swinging process of the gravity member 23, the inner cylinder 21 is in a vibrating state under the pressure of the gravity member 23. The setting of the elastic member 25 enables the inner cylinder 21 to quickly return to its original position. The inner cylinder 21 touches the external annular varistor during the vibration process. During the vibration process, the annular varistor causes the heavier portion to rotate downward and be in the same plane. The heavier portion is also the part where impurities gather, so it is convenient to perform local focused cleaning on the portion of the annular varistor where impurities are concentrated, thereby improving production efficiency and the stability of production quality. At the same time, the vibration process causes the annular varistor to slide along the guide assembly 5.

[0032] By arranging an inner cylinder 21, an outer cylinder 22, a gravity member 23, a first driving member 24, and an elastic member 25 in the vibration device 2, multiple annular varistors to be cleaned are in a vibrating state while sliding along the guide assembly 5, so that the parts with higher specific gravity are located at the bottom, thereby facilitating the focused cleaning of areas with more impurities, improving cleaning efficiency, ensuring the stability of production quality, and meeting production requirements.

[0033] The guide assembly 5 includes a rotating shaft 51, a support shaft 52 and a connecting member 53. The rotating shaft 51 and the support shaft 52 are arranged in parallel and at a distance from each other. The rotating shaft 51 and the support shaft 52 are connected by a connecting member 53. There are three support shafts 52. Three support shafts 52, one rotating shaft 51 and multiple connecting members 53 constitute the guide assembly 5, thereby improving the stability of the structure of the guide assembly 5.

[0034] The support shaft 52 is provided with helical teeth, and the helical teeth are arranged along the length direction of the support shaft 52 .

[0035] The vibration device 2 also includes a second driving member, which drives the rotating shaft 51 to rotate. The second driving member (not shown) drives the rotating shaft 51 to rotate, and the synchronous support shaft 52 rotates. The setting of the helical teeth causes the annular varistors to move along the conveying direction and enter the next process one by one.

[0036] The cleaning device 3 includes a cleaning agent nozzle 31, a brush head assembly 32 and a clean water nozzle 33. The cleaning agent nozzle 31, the brush head assembly 32 and the clean water nozzle 33 are arranged in sequence on the inner cylinder 21 along the conveying direction. First, the cleaning agent nozzle 31 sprays the cleaning liquid, and the cleaning liquid adheres to the surface of the annular varistor. The brush head assembly 32 applies pressure to the surface of the annular varistor to clean it. The clean water nozzle 33 sprays clean water to flush the dirt on the surface of the annular varistor to complete the cleaning process.

[0037] The drying device 4 includes a plurality of heating elements 41 and a plurality of fixing parts 42. The fixing parts 42 are arranged on the inner wall of the inner cylinder 21. The heating element 41 is installed on the fixing parts 42. The light beam emitted by the heating element 41 is arranged at an angle to the central axis of the inner cylinder 21. The heating element 41 is annular and fixed on the fixing part 42. The fixing part 42 is connected to the inner wall of the inner cylinder 21. The angle of the fixing part 42 is adjustable so that the light beam emitted by the heating element 41 is irradiated at different positions on the surface of the annular varistor, so that the surface of the annular varistor is heated evenly, thereby achieving the purpose of rapid drying.

[0038] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
