Abstract
Description
Technical Field
[0001] This utility model relates to an automatic step-by-step glazing device for disc-shaped suspension porcelain insulators, belonging to the technical field of porcelain insulator manufacturing equipment. Background Technology
[0002] As a critical insulating component in power transmission lines, the quality of porcelain insulators directly affects the safe and stable operation of the power grid. Traditional porcelain insulator glazing processes are mostly manual, resulting in low efficiency, uneven glaze layers, and high labor intensity.
[0003] To improve performance, some insulators currently use different glazes on the shed and the head (gluing section). The glaze on the shed prioritizes appearance and electrical properties, such as gloss, while the glaze on the gluing section uses compression glaze, focusing more on the mechanical strength of the ceramic component. Given the differences in function, formulation, and coefficient of expansion of these two glazes, strict control must be exercised during the glazing process to avoid excessive mixing of the two glazes, which could affect the mechanical and insulating properties of the insulator and increase the zero-value rate of the product. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, this utility model proposes an automatic step-by-step glazing device for disc-shaped suspension porcelain insulators. Compared to manual glazing, this device applies glaze to the head and umbrella disc of the porcelain insulator blank in steps using a mechanical device, resulting in high consistency of glazing quality, good uniformity of the glaze layer, stable product performance, and high production efficiency.
[0005] This utility model relates to an automatic step-by-step glazing equipment for disc-shaped suspension porcelain insulators, including: a glazing station, a drying station, a tape wrapping station, and a glazing robot.
[0006] The glazing station is equipped with a compression glaze tank and an electric porcelain glaze tank;
[0007] The drying station is equipped with a drying chamber, which contains a drying mechanism.
[0008] The tape winding station is equipped with a dry blank rotating fixture; the dry blank rotating fixture is equipped with a rotating mechanism and a dry blank placement platform, the dry blank placement platform is fixed on the rotating mechanism, and the rotating mechanism is set on the fixture lifting and transfer mechanism; the fixture lifting and transfer mechanism is equipped with a lifting component and a translation component; the lifting component is set on the translation displacement end of the translation component, and the rotating mechanism is set on the lifting displacement end of the lifting component.
[0009] The corresponding tape winding station is equipped with a tape feeding mechanism, including: a tape tray, a stripping plate and a magnetic powder separator; the tape tray is used to hold the tape roll, and the stripping plate is set between the tape tray and the magnetic powder separator to peel the tape and the tape substrate;
[0010] Glazing robotic arms are used to grab and transfer dry blanks.
[0011] The corresponding tape winding station is also equipped with a sensor to measure the height position of the head of the dry blank; preferably, a through-beam infrared sensor is used.
[0012] Compared with the prior art, the present invention has the following technical effects:
[0013] 1) The head of the blank of the disc suspension porcelain insulator can be first coated with compressed glaze, and after the glaze is dried, it can be wrapped with tape for protection. Then, the umbrella part of the blank of the disc suspension porcelain insulator can be coated with electric porcelain glaze. This can avoid excessive contact between electric porcelain glaze and compressed glaze, reduce the scrap rate, and ensure that the disc suspension porcelain insulator has excellent electrical and mechanical properties.
[0014] 2) The tape wrapping is done mechanically, which ensures the consistency of the wrapping height. Attached Figure Description

Detailed Implementation
[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0018] Example 1
[0019] like Figure 1 As shown, this embodiment includes: a glazing station, a drying station, a tape wrapping station, and a glazing robot 400; the glazing robot is used to grab and transfer dry blanks between the glazing station and the drying station, as well as between the tape wrapping station and the glazing station.
[0020] The glazing station is equipped with a compression glaze tank 101 and an electric porcelain glaze tank 102.
[0021] The drying station is equipped with a drying chamber 201, and a drying mechanism 202 is installed in the drying chamber 201. The drying chamber 201 is located on the opposite side of the glazing robot 400 and opens towards the direction of the dry blank. By setting the drying chamber 201, it can isolate the entry of cold air from the outside to a certain extent, so as to avoid the cold air from affecting the drying effect. The drying mechanism 202 consists of an electric heating tube and a high-power blower, which can generate hot air in a short time to promote the rapid drying of the compressed glaze at the head of the blank.
[0022] The tape winding station is equipped with a dry blank rotating fixture 300; the dry blank rotating fixture 300 is equipped with a rotating mechanism and a dry blank placement platform 301, the dry blank placement platform 301 is fixed on the rotating mechanism (not shown in the figure), the rotating mechanism is preferably a direct drive turntable; the rotating mechanism is set on the fixture lifting and transfer mechanism (not shown in the figure); the fixture lifting and transfer mechanism is equipped with a lifting component and a translation component, the lifting component is set on the translation displacement end of the translation component, and the rotating mechanism is set on the lifting displacement end of the lifting component; the lifting component and the translation component are preferably linear motor modules respectively.
[0023] The corresponding tape winding station is also equipped with a tape feeding mechanism 500 and a sensor 600.
[0024] The tape feeding mechanism 500 includes: a tape tray 501, a stripping plate 502, and a magnetic powder separator 503; the tape tray 501 is used to hold tape rolls, which are placed horizontally; the stripping plate 502 is located between the tape tray 501 and the magnetic powder separator 503, and has an inclined opening for peeling the tape from the tape substrate; the magnetic powder separator 503 is used to control the tape tension.
[0025] Sensor 600 is fixed on the bracket and is used to sense the head of the dry blank.
[0026] In this embodiment, the dry blank of the disc-shaped suspension porcelain insulator is first placed upside down on the dry blank placement platform 301. Then, the dry blank is lifted out of the dry blank placement platform 301 by the glazing robot 400. During the lifting, the robot makes contact with the umbrella disc near the head. The dry blank is then transferred to the compressed glaze pool 101 so that the head of the dry blank is wetted with compressed glaze.
[0027] After applying the compressed glaze, the dry blank is transferred to the drying station and placed in the dry blank placement platform 301. The rotating mechanism drives the dry blank placement platform 301 to rotate, and the drying mechanism 202 dries the compressed glaze on the head of the dry blank during this process. After drying the compressed glaze, the translation component in the jig lifting and transfer mechanism drives the dry blank placement platform 301 to translate and move the dry blank to the tape winding station. Then, the lifting component in the jig lifting and transfer mechanism drives the dry blank placement platform 301 to rise and fall until the sensor 600 detects that the bottom of the umbrella tray is aligned with the top of the tape at the feeding plate 502. The operator guides the dry blank to attach one end of the tape to the head of the dry blank, and the rotating mechanism drives the dry blank to rotate, so that the tape is wrapped around the head of the dry blank. According to the width of the tape and the length of the head of the dry blank, the lifting component raises and lowers the dry blank during the rotation of the rotating mechanism, and the dry blank is gradually wrapped with tape during the rotation of the dry blank. To ensure that the tape completely covers the head of the dry blank without leaving any gaps, the head circumference l, tape width d, rotation speed v1, and lifting speed v2 should achieve the following relationship: This allows the head of the dry blank with compressed glaze to be completely wrapped with tape. Based on the length of the head of the dry blank, the lifting height of the lifting component is set. After reaching the corresponding height, the lifting component stops lifting and the rotating mechanism stops rotating. The translation component in the jig lifting and transfer mechanism moves the blank a certain distance away, so that the tape is removed from the substrate. Then, the tape is cut with a blade, and the tape wrapping operation is completed.
[0028] Afterwards, the glazing robot 400 clamps the head of the dry blank, flips the dry blank 180° and immerses it in the electric porcelain glaze pool 102, so that all the parts of the dry blank that have not been coated with compressed glaze are completely wetted with electric porcelain glaze, and then it is dried, thus completing the glazing operation of the dry blank.
[0029] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
