Description

Technical Field

[0001] This utility model relates to the field of insulator production technology, and in particular to a finished product screening device for glass insulator production. Background Technology

[0002] An insulator is a substance that does not conduct electric current under normal conditions; it is also called a dielectric. The characteristics of an insulator are that the positive and negative charges in the molecules are tightly bound together, and there are very few charged particles that can move freely. Its resistivity is very high, above 107 ohm-meters. Therefore, under normal circumstances, the macroscopic current formed by the movement of free charges under the action of an external electric field can be ignored, and it is considered a non-conductive substance. Most common insulators are made of glass. In the production process of insulators, since the size of each insulator part is different, a screening device is needed to screen the insulators.

[0003] A search revealed that patent CN211463851U discloses a screening device for manufacturing porcelain insulators. By incorporating a vibrating motor, the screen frame shakes, accelerating the screening speed and improving efficiency. A spring further intensifies the shaking, further enhancing efficiency. A stirring rod, activated by a stirring motor, rotates the stirring shaft, stirring the porcelain insulators and clearing blockages. A weighing device allows for the weighing of the insulators, screening those that do not meet the weight requirements. An inclined plate prevents insulators from falling into the weighing hopper. An electronic display screen provides a clear view of the insulator weight, further improving screening efficiency.

[0004] Insulators are insulators used on high-voltage lines and belong to the category of insulators. This patent uses vibration to screen insulators during use. Since insulators are made of various materials, such as ceramics and glass, screening these two types of insulators by vibration can easily cause ceramics and glass to break due to excessive vibration amplitude. Furthermore, the excessive falling distance of the insulators after screening can also easily cause them to break due to impact force, resulting in poor protection for the insulators and room for improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a finished product screening device for glass insulator production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A finished product screening device for glass insulator production includes a screening table, a positioning frame fixedly connected to the upper surface of the screening table, an industrial camera fixedly connected to the upper surface of the positioning frame, an industrial control host fixedly connected to the left side of the positioning frame, a hydraulic push rod fixedly connected to the right side of the positioning frame, a push plate fixedly connected to the output end of the hydraulic push rod, a screening groove formed on the upper surface of the screening table, a slot formed on the front of the screening table, a collection frame inserted into the inner wall of the slot, a screening assembly fixedly connected to the inner wall of the screening groove, the screening assembly including a fixed frame, a strip frame fixedly connected to the upper surface of the fixed frame, and a conveyor belt installed on the inner wall of the strip frame.

[0008] Preferably, the camera end of the industrial camera extends to the lower surface of the positioning frame, and the positions of the industrial camera and the push plate correspond to the positions of the conveyor belt.

[0009] Preferably, a sliding groove is provided on the left side of the fixed frame, a movable frame is slidably connected to the inner wall of the sliding groove, a drive motor is fixedly connected to the inner bottom wall of the fixed frame, a lead screw is fixedly connected to the output end of the drive motor, a strip groove is provided on the inner wall of the sliding groove, a slider is slidably connected to the inner wall of the strip groove, the top end of the lead screw is rotatably connected to the inner top wall of the fixed frame, and the slider is threadedly connected to the lead screw. When the lead screw rotates, it can drive the slider to move up and down in the strip groove.

[0010] Preferably, the left side of the slider is fixedly connected to the right side of the movable frame, the electric push rod is fixedly connected to the surface of the rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the rotating frame. When the electric push rod drives the strip plate to tilt through the round shaft and the movable frame, the electric push rod itself can also rotate on the inner wall of the rotating shaft and the rotating frame, without affecting the normal tilting effect of the strip plate.

[0011] Preferably, the upper surface of the movable frame is provided with a rectangular groove, and a rotating frame is fixedly connected to the inner bottom wall of the rectangular groove. An electric push rod is rotatably connected to the inner wall of the rotating frame via a rotating shaft. The output end of the electric push rod is fixedly connected to the movable frame via a round shaft. A strip plate is slidably connected to the upper surface of the movable frame, and a rotating plate is fixedly connected to the lower surface of the strip plate. The rotating plate is rotatably connected to the inner wall of the rectangular groove via a round rod. Buffer components are fixedly connected to the four corners of the upper surface of the strip plate, and a screening frame is fixedly connected to the top of the buffer components. The output end of the electric push rod is rotatably connected to the round shaft, and the round shaft is fixedly connected to the inner wall of the movable frame. After the output end of the electric push rod extends, it can drive the movable frame to move left and right below the strip plate via the round shaft, thereby causing the strip plate to rotate and tilt around the round rod.

[0012] Preferably, the buffer assembly includes a sleeve, a buffer spring is fixedly connected to the inner bottom wall of the sleeve, a pressure plate is slidably connected to the inner wall of the sleeve, a top rod is fixedly connected to the upper surface of the pressure plate, the top end of the top rod is fixedly connected to the lower surface of the screening frame, and a rubber pad is fixedly connected to the inner bottom wall of the screening frame.

[0013] Preferably, the end of the buffer spring away from the inner bottom wall of the sleeve is fixedly connected to the lower surface of the pressure plate.

[0014] Preferably, the top end of the sleeve has a circular through hole that matches the top rod, and the position of the screening frame corresponds to the position of the screening trough. The screening frame can fall from the screening trough, so that the insulator inside the screening frame can fall into the collection frame after tilting.

[0015] The beneficial effects of this utility model are as follows:

[0016] By setting up the screening component, during use, the screening frame can contact the screened insulator, and at the same time, the drive motor drives the movable frame to move downward through the lead screw and slider, which can greatly shorten the falling stroke of the insulator, thereby avoiding the problem of glass insulator breaking during the falling process and improving the protection effect of the insulator.

[0017] By incorporating a buffer component, the elasticity of the rubber pad and the reaction force generated by the buffer spring can reduce the impact force generated when the insulator falls off the conveyor belt, thereby further improving the buffering effect on the glass insulator.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1 , Figure 2 and Figure 3 A finished product screening device for glass insulator production includes a screening table 1, a positioning frame 2 fixedly connected to the upper surface of the screening table 1, an industrial camera 3 fixedly connected to the upper surface of the positioning frame 2, the camera end of the industrial camera 3 extending to the lower surface of the positioning frame 2, an industrial control host 4 fixedly connected to the left side of the positioning frame 2, a hydraulic push rod 5 fixedly connected to the right side of the positioning frame 2, and a push plate 6 fixedly connected to the output end of the hydraulic push rod 5.

[0025] The upper surface of the screening table 1 is provided with a screening groove, and the front of the screening table 1 is provided with a slot. A collection frame 7 is inserted into the inner wall of the slot. A screening assembly is fixedly connected to the inner wall of the screening groove. The screening assembly includes a fixed frame 8. A strip frame 9 is fixedly connected to the upper surface of the fixed frame 8. A conveyor belt 10 is installed on the inner wall of the strip frame 9. The positions of the industrial camera 3 and the push plate 6 are corresponding to the positions of the conveyor belt 10. A sliding groove is provided on the left side of the fixed frame 8. A movable frame 11 is slidably connected to the inner wall of the sliding groove. A drive motor 12 is fixedly connected to the inner bottom wall of the fixed frame 8. A lead screw 13 is fixedly connected to the output end of the drive motor 12. A strip groove is provided on the inner wall of the sliding groove. A slider 14 is slidably connected to the inner wall of the strip groove. The top end of the lead screw 13 is rotatably connected to the inner top wall of the fixed frame 8, and the slider 14 is threadedly connected to the lead screw 13. The left side of the slider 14 is fixedly connected to the right side of the movable frame 11.

[0026] A rectangular groove is provided on the upper surface of the movable frame 11. A rotating frame 15 is fixedly connected to the inner bottom wall of the rectangular groove. An electric push rod 17 is rotatably connected to the inner wall of the rotating frame 15 via a rotating shaft 16. The electric push rod 17 is fixedly connected to the surface of the rotating shaft 16. The rotating shaft 16 is rotatably connected to the inner wall of the rotating frame 15. A movable frame 19 is fixedly connected to the output end of the electric push rod 17 via a round shaft 18. The output end of the electric push rod 17 is rotatably connected to the round shaft 18. The round shaft 18 is fixedly connected to the inner wall of the movable frame 19. A strip plate 20 is slidably connected to the upper surface of the movable frame 19. A rotating plate 21 is fixedly connected to the lower surface of the strip plate 20. The rotating plate 21 is rotatably connected to the inner wall of the rectangular groove via a round rod 22. Buffer components are fixedly connected to the four corners of the upper surface of the strip plate 20. A screening frame 23 is fixedly connected to the top of the buffer components.

[0027] The conveyor belt 10 transports insulators of different sizes. When it moves to the position frame 2, the industrial camera 3 can visually inspect the size of each insulator. After the inspection, it automatically determines whether the insulator needs to be screened. When a large insulator is detected, the hydraulic push rod 5 is automatically started and the push plate 6 drives the insulator to move to the left until it falls into the screening frame 23. At this time, the drive motor 12 drives the movable frame 11 to descend as a whole through the lead screw 13 and the slider 14. After it descends to a suitable height, the electric push rod 17 is started and the strip plate 20 is tilted to the left through the round shaft 18 and the movable frame 19, so that the insulator in the screening frame 23 can fall into the collection frame 7, completing the screening operation of insulators of different sizes.

[0028] Example 2: Refer to Figure 1 , Figure 2 and Figure 4 The buffer assembly includes a sleeve 24, a buffer spring 25 fixedly connected to the inner bottom wall of the sleeve 24, a pressure plate 26 slidably connected to the inner wall of the sleeve 24, one end of the buffer spring 25 away from the inner bottom wall of the sleeve 24 fixedly connected to the lower surface of the pressure plate 26, a top rod 27 fixedly connected to the upper surface of the pressure plate 26, a circular through hole adapted to the top rod 27 is opened at the top of the sleeve 24, and the position of the screening frame 23 corresponds to the position of the screening trough. The top of the top rod 27 is fixedly connected to the lower surface of the screening frame 23, and a rubber pad 28 is fixedly connected to the inner bottom wall of the screening frame 23.

[0029] After the insulator is pushed onto the conveyor belt 10 by the push plate 6 and falls into the screening frame 23, the rubber pad 28 first contacts the insulator and absorbs part of the impact force using its own elasticity. At the same time, the screening frame 23 can drive the four push rods 27 and the pressure plate 26 to squeeze the buffer spring 25. The reaction force generated by the buffer spring 25 absorbs part of the impact force again, thus ensuring that the insulator will not be damaged after falling into the screening frame 23, further improving the protection effect of the insulator.

[0030] Working principle: First, the processed insulators are placed on the conveyor belt 10 for conveying. When passing the positioning frame 2, the industrial camera 3 can automatically detect the size of each insulator. After detecting a larger insulator, the hydraulic push rod 5 is automatically activated, driving the push plate 6 to move to the left. The push plate 6 can push the larger insulator to the position above the screening frame 23. At this time, the rubber pad 28 can deform to absorb part of the impact force generated by the insulator falling downward. At the same time, the screening frame 23 can drive the pressure plate 26 to squeeze the buffer spring 25 through the top rod 27. The deformation and reaction force generated by the buffer spring 25 can absorb part of the impact force, thereby improving the protection of the insulator. To enhance protection, after the insulator falls onto the screening frame 23, the drive motor 12 lowers the slider 14 via the lead screw 13, thereby lowering the movable frame 11 as a whole. Once the frame reaches a suitable height, the electric push rod 17 is activated and tilts the strip plate 20 via the round shaft 18 and the movable frame 19. Simultaneously, the electric push rod 17 can also rotate on the inner wall of the rotating frame 15 via the rotating shaft 16, causing the strip plate 20 to tilt the screening frame 23. At this point, the insulator inside the screening frame 23 can slide from the screening frame 23 into the collection frame 7, completing the screening operation for insulators of different sizes. This shortens the distance the insulator falls, thereby improving the protection effect on the insulator and preventing the glass insulator from breaking.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
