DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0030] See also Figures 1 to 6 The defective product rejection mechanism 100 of the capped resistor ceramic matrix includes a frame 1, a screen drum 2, a driving mechanism 3 and a first collecting box 4; the screen drum 2 is rotatably installed on the frame 1 along its radial axis, and the opposite ends of the screen drum 2 are respectively provided with a feed port 21 and a discharge port 22, and the screen drum 2 is gradually inclined downward in the direction from the feed port 21 to the discharge port 22, and the inner side wall of the screen drum 2 is provided with a plurality of screen holes 23, and the plurality of screen holes 23 are arranged at intervals along the circumference of the screen drum 2, and the aperture of the screen holes 23 is larger than the diameter of the ceramic rod 210 and smaller than the diameter of the cap 220; the driving mechanism 3 is arranged on the frame 1, and the driving mechanism 3 is connected to the screen drum 2 for driving the screen drum 2 to rotate; the first collecting box 4 is arranged on the frame 1, and the first collecting box 4 is adapted to the length of the screen drum 2, and the first collecting box 4 extends into the screen drum 2, and the box opening is arranged upward.

[0031] In the defective product rejection mechanism 100 for a capped resistor ceramic matrix provided by the utility model, the first collection box 4 is arranged in the screen drum 2, and the first collection box 4 is installed on the frame 1, and will not rotate with the screen drum 2, and the box opening of the first collection box 4 is arranged upward. When it is used specifically, the capped resistor ceramic matrix 200 is firstly put into the screen drum 2 from the feed port 21, and then the screen drum 2 rotates, and the aperture of the screen hole 23 is larger than the diameter of the ceramic rod 210 and smaller than the diameter of the cap 220. If there are defective products, this The end of the defective product without the cap 220 will be stuck in the sieve hole 23 and rotate with the sieve drum 2. When the defective product rotates to a high place, it will fall into the first collecting box 4 under the action of its own gravity. The diameters of both ends of the qualified products are larger than the aperture of the sieve hole 23 and will not be stuck by the sieve hole 23. Similarly, under the action of its own gravity, it will move from the discharge port 22 to the outside of the sieve drum 2. In this way, the capped resistor ceramic matrix 200 can be screened to remove the defective products. The structure is simple, easy to use, and has a high removal efficiency, which reduces the labor intensity of workers.

[0032] See also Figure 6 It should be noted that the capped resistor ceramic substrate 200 includes a ceramic rod 210 and two caps 220 . The caps 220 are disposed at opposite ends of the ceramic rod 210 . The diameter of the caps 220 is greater than the diameter of the ceramic rod 210 .

[0033] Specifically, in order to prevent the defective products from accumulating in the first collecting box 4 and causing them to overflow outside the first collecting box 4, in this embodiment, the first collecting box 4 is further provided with a collecting port 41, the collecting port 41 is connected to the box space inside the first collecting box 4, and the collecting port 41 extends from the discharge port 22 to the outside of the screen drum 2. In this way, the defective products can be discharged to the first collecting box 4 through the collecting port 41, thereby preventing the defective products from accumulating, reducing the load of the first collecting box 4, and extending the service life of the first collecting box 4.

[0034] Specifically, since the first collecting box 4 is arranged in the screen drum 2, it is inconvenient to collect the defective products in the first collecting box 4. Therefore, in the present embodiment, the first collecting box 4 is arranged to be gradually inclined downward in the direction from the feed port 21 to the discharge port 22. Such an arrangement allows the defective products to be discharged from the collecting port 41 to the outside of the first collecting box 4 under the action of their own gravity, which is convenient to use.

[0035] Specifically, in order to screen the capped resistor ceramic matrix 200 as comprehensively as possible, it is necessary to make the capped resistor ceramic matrix 200 stay in the sieve drum 2 for as long as possible for screening, so the inclination of the sieve drum 2 is smaller, and relative to the first collecting box 4, defective products need to be discharged as quickly as possible. Therefore, in this embodiment, the inclination angle of the first collecting box 4 is greater than the inclination angle of the sieve drum 2. With this arrangement, defective products can be discharged as quickly as possible.

[0036] Specifically, in order to improve the screening efficiency, a plurality of sieve holes 23 constitute a sieve hole group, and a plurality of sieve hole groups are provided, and the plurality of sieve hole groups are arranged at intervals along the radial direction of the sieve drum 2 .

Each roller 31 is rotatably installed on the frame 1 along its own axial direction. Both rollers 31 are in contact with the outer side surface of the screen drum 2. The driving motor 32 is connected to one of the rollers 31 for driving the roller 31 to rotate. Specifically, both ends of each roller 31 are fixedly mounted on the frame 1 through bearing seats, and the distance between the two rollers 31 is smaller than the diameter of the sieve drum 2. The sieve drum 2 is placed on the two rollers 31, and the two rollers 31 are consistent in radial direction with the sieve drum 2. When in use, the driving motor 32 drives one of the rollers 31 to rotate. Since the roller 31 is in contact with the sieve drum 2, there is friction between the two. When the roller 31 rotates, the sieve drum 2 is driven to rotate by the friction, and the other roller 31 plays a role of cooperating with the roller 31 to support the sieve drum 2 on the one hand, and plays a role of auxiliary rolling on the other hand. With this arrangement, the sieve drum 2 can be detachably mounted on the two rollers 31, which is convenient for replacing the sieve drum 2, and the driving mechanism 3 can drive different models of sieve drums 2.

[0038] Specifically, the outer periphery of the roller 31 and the outer periphery of the screen drum 2 are both provided with anti-slip structures.

In this embodiment, the capped resistor ceramic matrix defective product removal mechanism 100 also includes a second collection box 5, which is arranged on the frame 1 and directly below the sieve cylinder 2. With this arrangement, the defective products can be collected by the second collection box 5 to prevent them from being scattered around the periphery of the equipment.

[0040] Specifically, the specific form of the sieve drum 2 is not limited. In the present embodiment, the sieve drum 2 includes two mounting plates 24 and a plurality of mounting columns 25. The two mounting plates 24 are spaced apart along a first direction, and each mounting plate 24 is arranged in a ring shape. The plurality of mounting columns 25 are located between the two mounting plates 24, and the plurality of mounting columns 25 are spaced apart along the circumference of the mounting plates 24. Both ends of each mounting column 25 are respectively connected to the two mounting plates 24, wherein the gap between two adjacent mounting columns 25 constitutes the sieve hole 23.

[0041] Specifically, in order to enhance the connection strength of the sieve drum 2, the sieve drum 2 also includes a plurality of connecting plates 26 and a plurality of connecting columns 27. The connecting plates 26 are arranged in a ring shape. The plurality of connecting plates 26 are located between the two mounting plates 24 and are arranged at intervals along the first direction. Each of the connecting plates 26 is sleeved on the outer periphery of the plurality of connecting columns 27. The plurality of connecting columns 27 are arranged at intervals along the circumference of the mounting plate 24. Each of the connecting columns 27 passes through the two ends of the plurality of connecting plates 26 and is respectively connected to the two connecting plates 26.

[0042] Specifically, the defective capped resistor ceramic matrix rejection mechanism 100 also includes a loading device and a collecting box.
