Description

Technical Field

[0001] The utility model relates to the technical field of chip varistor production devices, and more specifically, to an intelligent sorting device for zinc oxide resistor chips. Background Art

[0002] A zinc oxide resistor chip is a non-linear resistor element made mainly of zinc oxide. Under a certain voltage, its resistance value is very small, while when the voltage exceeds a certain value, the resistance increases sharply. Different application scenarios have different performance requirements for resistor chips. Through sorting, resistor chips that meet specific requirements can be selected. Secondly, sorting can ensure the consistency of product quality, avoid the mixing of resistor chips with large performance differences, and improve the reliability of the overall product.

[0003] In the Chinese utility model patent, such as the utility model of CN221157729U, a sorting device for chip varistors is disclosed, including a sorting box. In the sorting process, through the cooperation of a motor, an adjusting shaft and a reversing plate, the sorting mechanism of the device can be effectively simplified, the complexity of the sorting mechanism can be reduced, facilitating its maintenance and overhaul, and it has high performance.

[0004] However, during the use of the above technology, when sorting resistor chips, only two different types of resistor chips can be sorted out, reducing the fineness and efficiency of sorting. In actual use, the sorting device may classify based on more performance indicators. For example, considering parameters such as the withstand voltage ability and energy absorption ability of resistor chips, they are classified into categories with different performance levels of high, medium, and low. This can enable resistor chips with different qualities and performances to be more accurately applied to corresponding products, improving the quality and reliability of the overall product.

The technical problem to be solved by the utility model is that when sorting resistor chips, only two different types of resistor chips can be sorted out, reducing the fineness and efficiency of sorting.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A baffle is fixedly installed on the side surface of the conveying table.

[0008] A plurality of drive boxes are symmetrically installed on the top surface of the rotating base. A sorting box is rotatably connected to the top surface of each drive box. Each drive box drives the rotation of the sorting box through a drive mechanism. A fixed shaft is fixedly installed in each sorting box.

[0014] In a preferred embodiment, a square groove is formed in each fixed shaft, and each square column is inserted into the correspondingly positioned square groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in conjunction with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1-4 , the intelligent sorting device for zinc oxide varistor chips includes a conveying table 1 and a rotating seat 2. A detection box 5 is fixedly installed on the top surface of the conveying table 1. A conveyor belt 6 is rotatably connected inside the conveying table 1. A guiding mechanism is provided on the top surface of the conveying table 1. A baffle 7 is fixedly installed on the side surface of the conveying table 1;

[0026] On the top surface of the rotating seat 2, a plurality of driving boxes 3 are symmetrically installed. On the top surface of each driving box 3, a sorting box 4 is rotatably connected. Each driving box 3 drives the rotation of the sorting box 4 through a driving mechanism. A fixed shaft 14 is fixedly installed inside each sorting box 4. A plurality of rotating plates 13 are rotatably connected to the outside of each fixed shaft 14. An assembly seat 19 is fixedly installed on the outside of each rotating plate 13. A pin 16 is elastically connected inside each assembly seat 19. A plurality of card slots 15 are formed on the top surface of each sorting box 4, and each pin 16 is inserted into the corresponding card slot 15.

[0027] As Figures 1-4 shown, the specific implementation method is as follows: By setting the guiding mechanism, each conveyed varistor chip is located at the center of the conveyor belt 6, which is convenient for falling into the corresponding sorting box 4. Through the rotating seat 2, a plurality of sorting boxes 4 can be alternately rotated under the conveying table 1, which is convenient for taking out the varistor chips in the full sorting box 4 without affecting the normal detection of the detection line. By setting the driving mechanism and the rotating plates 13, the sorting box 4 can be divided into multiple areas by a plurality of rotating plates 13 to correspond to different qualities. The driving mechanism drives the corresponding area to correspond to the baffle 7, and then the varistor chips fall into this area. By setting the pins 16, the fixed shafts 14, and the card slots 15, the size of each area can be adjusted by rotating the rotating plates 13, and at the same time, the rotating plates 13 are fixed by the pins 16 being clamped in the card slots 15.

[0028] Each driving mechanism includes a motor 12, and each motor 12 is fixedly installed on the bottom wall of the driving box 3. The output shaft of each motor 12 penetrates the driving box 3 and is fixedly installed with a square column 18, and each square column 18 is inserted into the corresponding fixed shaft 14.

[0029] By the square column 18 being clamped in the fixed shaft 14, the fixed shaft 14 can be driven to rotate by the rotation of the square column 18, and then the sorting box 4 is driven to rotate.

[0030] The diversion mechanism includes a plurality of electric telescopic rods 8, and the plurality of electric telescopic rods 8 are respectively symmetrically installed on the two inner side walls of the conveying table 1. A plurality of electric telescopic rods 8 on the same side are all commonly installed with a diversion plate 9.

[0031] The electric telescopic rod 8 can drive the diversion plate 9 to move towards the central axis direction of the conveying table 1, thereby pushing the resistor sheet to remain in the central part of the conveying table 1.

[0032] The diversion mechanism further includes two fixed seats 11, and the two fixed seats 11 are respectively symmetrically installed on the two inner side walls of the conveying table 1. An elastic band 10 is fixedly connected inside each fixed seat 11, and the other end of each elastic band 10 is fixedly connected to the side surface of the corresponding diversion plate 9.

[0033] Through the movement of the diversion plate 9, the elastic band 10 is tensioned and is in an inclined state through the elastic band 10, thereby expanding the diversion range.

[0034] The upper end surface of each assembly seat 19 is fixedly connected with a spring 17, and the other end of each spring 17 is fixedly connected to the top end of the pin 16.

[0035] A square groove is formed in each fixed shaft 14, and each square column 18 is inserted into the corresponding square groove.

[0036] When the utility model is in use, the conveyor belt 6 is driven to rotate in the conveying table 1 by an external drive source, and then the resistor sheet is placed above the conveyor belt 6, thereby conveying the resistor sheet. Then, by starting a plurality of electric telescopic rods 8, the diversion plate 9 is driven to move, thereby tensioning the elastic band 10. The side surface of the elastic band 10 and the outer side of the diversion plate 9 block the resistor sheet, thereby realizing the diversion of the resistor sheet and making the resistor sheet always located in the central part of the conveyor belt 6;

[0037] Then, the pin 16 is lifted upward and the rotating plate 13 is rotated. The size of different regions can be adjusted according to the yield rate of each grade of the resistor sheet. Then, the pin 16 is released, and under the action of the spring 17, the pin 16 is inserted into the card slot 15 to fix the rotating plate 13;

[0038] Then, the resistor sheet is conveyed into the detection box 5. The detection box 5 detects the resistor sheet and differentiates the grades. Then, an electrical signal is transmitted to the motor 12, and the sorting box 4 is driven to rotate by driving the motor 12, so that this region is aligned with the baffle 7, thereby making the resistor sheet fall into the specifically divided region of the corresponding grade;

[0039] Next, when the resistor chips in the sorting box 4 are full, the rotating base 2 can be driven to rotate by an external drive circle, moving another sorting box 4 to the bottom of the conveying table 1. Then, the fixed shaft 14 can be directly disengaged from the square column 18, so that the sorting box 4 can be removed from the drive box 3, and then the resistor chips can be taken out.

[0040] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
