Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic module production technology, and in particular relates to a photovoltaic module conveying device with high reliability and rotation function. [Background Technology]

[0002] The entire manufacturing process of photovoltaic modules involves multiple steps, including stringing, stacking, microscopic inspection, pre-lamination EL inspection, lamination, edge trimming, visual inspection, framing, junction box installation, potting, curing, backside cleaning, insulation withstand voltage testing, frontside cleaning, IV testing, post-lamination EL inspection, final inspection, sorting, and packaging. After potting and curing, or after backside and frontside cleaning, some areas may remain uncleaned, requiring manual wiping of oily areas or cleaning of residual EVA or silicone from the photovoltaic modules. To improve the efficiency of manual wiping and maintain the overall production cycle of the assembly line, multiple cleaning stations are needed for simultaneous cleaning operations. Chinese Patent Publication No. CN220563480U discloses a photovoltaic module cleaning support and conveying platform with a rotating function. A lifting support platform is set in the space between two parallel and independent conveyor lines, and a sufficiently large rotating support platform is set on the lifting support platform. The rotating support platform is horizontally rotated on the support frame via a turntable, which can meet the multi-angle rotation operation requirements of photovoltaic modules during cleaning and inspection. However, this solution still has the following two problems:

[0003] (1) The rotating support platform is directly installed on the upper surface of the turntable. The installation between the two horizontal planes has no limit in the front-back or left-right directions, making positioning difficult during installation, which leads to difficulties in installing the rotating support platform.

[0004] (2) In order to ensure a sufficiently large support area, the lifting support platform is equipped with a sufficiently large support frame. In order to ensure the stability of the support frame’s up and down movement, cylinders are installed at the four corners of the support frame to drive the support frame to lift. The structure of the above-mentioned lifting support platform is complex, occupies a large space, and is not conducive to the layout of the production line.

[0005] Therefore, it is necessary to provide a photovoltaic module conveying device with high reliability and rotation function to solve the above-mentioned technical problems. [Utility Model Content]

It can improve the overall reliability of the rotating support mechanism, and the overall structure is simple, occupies little space, and is conducive to the layout of the production line.

[0007] The present invention achieves the above objectives through the following technical solution: a photovoltaic module conveying device with high reliability and rotation function, comprising a frame, a module conveying line disposed on the frame, a lifting module disposed between the module conveying lines, and a rotating support mechanism driven by the lifting module to move up and down;

[0008] The rotating support mechanism includes a lifting plate, a rotating component mounted on the lifting plate and capable of rotating around a vertical axis, a rotating support platform fixed to the upper end of the rotating component, and an angle locking module mounted on the lifting plate and locking the rotation angle position of the rotating support platform.

[0010] Furthermore, the component conveying line includes a pair of support profiles arranged parallel to the frame, a drive motor fixed on the support profiles, and a conveyor belt arranged on the support profiles and driven by the drive motor for cyclic conveying. The lifting module and the rotating support mechanism are arranged between the two conveyor belts.

[0011] Furthermore, the frame is provided with a support plate for mounting the lifting module between the component conveying lines. The lifting module includes a lifting drive component mounted on the support plate and a lifting rod that is driven by the lifting drive component to move up and down.

[0012] Furthermore, a plurality of guide rods are provided between the support plate and the lifting plate, and each guide rod is provided with a linear bearing at the position where it contacts the support plate.

[0013] Furthermore, the rotating assembly includes a rotating shaft disposed on the lifting plate and capable of rotating about a vertical axis, and a rotating seat fixed to the top of the rotating shaft.

[0014] Furthermore, a plurality of bearings are provided on the outer periphery of the rotating shaft, and a bearing sleeve is installed on the lifting plate by a plurality of screws, and the rotating shaft is rotatably disposed within the bearing sleeve via the bearings.

[0015] Furthermore, the lower end of the rotating shaft is provided with an upper limit stop to restrict the rotating shaft from moving upward along the axial direction. The diameter of the rotating seat is larger than that of the rotating shaft, and the lower surface of the rotating seat can contact the screw or the bearing sleeve to achieve the lower limit of the rotating shaft.

[0016] Furthermore, the outer periphery of the rotating seat is provided with a plurality of locking notches, and a pair of angle locking modules are provided and symmetrically arranged on the front and rear sides of the rotating seat.

[0017] Furthermore, the upper surface of the rotating seat is provided with the contour mounting groove, and the rotating arm is installed in the contour mounting groove by bolts.

[0018] Furthermore, the support member is a support plate or several support rods fixed on the rotating arm.

[0019] Compared with the prior art, the advantages of this utility model of a photovoltaic module conveying device with high reliability and rotation function are as follows:

[0020] (1) The rotating assembly includes a rotating shaft that is mounted on the lifting plate and can rotate around the vertical axis, and a rotating seat fixed to the top of the rotating shaft. The upper surface of the rotating seat is provided with a contour mounting groove.

Detailed Implementation Methods

[0034] Please refer to Figures 1-5 This embodiment is a highly reliable photovoltaic module conveying device 100 with a rotating function. The highly reliable photovoltaic module conveying device 100 with a rotating function includes a frame 1, a module conveying line 2 disposed on the frame 1, a lifting module 3 disposed between the module conveying lines 2, and a rotating support mechanism 4 driven by the lifting module 3 to move up and down. The rotating support mechanism 4 includes a lifting plate 41, a rotating component 42 disposed on the lifting plate 41 and capable of rotating around a vertical axis, a rotating support platform 43 fixed to the upper end of the rotating component 42, and an angle locking module 44 disposed on the lifting plate 41 and locking the rotation angle position of the rotating support platform 43. The rotating support platform 43 includes a rotating arm 431 and a support member 432 fixed to the rotating arm 431 and supporting the photovoltaic module. The upper end of the rotating component 42 is provided with a conforming mounting groove 428 that conforms to the rotating arm 431 and is used to position and install the rotating arm 431.

[0035] The component conveyor line 2 includes a pair of support profiles 21 arranged parallel to each other on the frame 1, a drive motor 22 fixed on the support profiles 21, and a conveyor belt 23 arranged on the support profiles 21 and driven by the drive motor 22 for cyclic conveying. The two conveyor belts 23 achieve synchronous rotation transmission through a drive shaft 24, which can ensure the synchronicity of the transmission. The lifting module 3 and the rotating support mechanism 4 are arranged between the two conveyor belts 23, occupying little space and facilitating the layout of the production line.

[0036] A support plate 11 for mounting a lifting module 3 is provided between the component conveyor line 2 and the frame 1. The lifting module 3 includes a lifting drive component 31 mounted on the support plate 11 and a lifting rod 32 driven by the lifting drive component 31 to move up and down. The lifting drive component 31 can be a cylinder or a servo motor, which is not limited here. To ensure the stability of the vertical movement of the rotary support mechanism 4, several guide rods 33 are provided between the support plate 11 and the lifting plate 41. Each guide rod 33 is provided with a linear bearing 34 at the contact position with the support plate 11. The guide rods 33 and the linear bearings 34 can ensure the stability of the vertical movement of the rotary support mechanism 4.

[0037] The rotating assembly 42 includes a rotating shaft 421 disposed on the lifting plate 41 and capable of rotating about a vertical axis, and a rotating seat 422 fixed to the top of the rotating shaft 421.

[0038] Several bearings are provided on the outer periphery of the rotating shaft 421, and a bearing sleeve 424 is installed on the lifting plate 41 by several screws 411. The rotating shaft 421 is rotated and installed in the bearing sleeve 424 through the bearings.

[0039] In this embodiment, the lifting drive 31 drives the lifting rod 32 to rise and push the rotating shaft 421, thereby causing the lifting plate 41 to move upward. The rotating shaft 421 is rotatably installed inside the bearing sleeve 424. In order to limit the axial movement of the rotating shaft 421, an upper limit member 426 is provided at the lower end of the rotating shaft 421 to limit the axial upward movement of the rotating shaft 421. In this embodiment, the upper limit member 426 is a limiting ring sleeved on the lower end of the rotating shaft 421. The outer periphery of the limiting ring is provided with a plurality of limiting blocks 4261 extending into the bottom end face of the bearing. When the lifting drive 31 drives the lifting rod 32 to rise and push the rotating shaft 421, thereby causing the lifting plate 41 to move upward, the limiting blocks 4261 abut against the bottom end face of the bearing to limit the upward movement of the rotating shaft 421. The diameter of the rotating seat 422 is larger than that of the rotating shaft 421. When the rotating shaft 421 is in a low position, the lower surface of the rotating seat 422 can contact the screw 411 or the bearing sleeve 424 to achieve the lower limit of the rotating shaft 421. If the top of the screw 411 is higher than the upper surface of the bearing sleeve 424, the lower surface of the rotating seat 422 contacts the screw 411 to achieve the lower limit of the rotating shaft 421. If the top of the screw 411 is lower than the upper surface of the bearing sleeve 424, the lower surface of the rotating seat 422 contacts the bearing sleeve 424 to achieve the lower limit of the rotating shaft 421.

[0040] The outer periphery of the rotating base 422 is provided with several locking notches 425. Angle locking modules 44 are provided in pairs and symmetrically arranged on the front and rear sides of the rotating base 422. Each angle locking module 44 includes a locking cylinder 441 and a locking block 442 driven by the locking cylinder 441 to move horizontally and extend into the locking notches 425 to lock the rotating base 422. In this embodiment, two locking notches 425 are provided, allowing the rotating support platform 43 to be locked when it rotates 180° or 360°. In other embodiments, more than two locking notches 425 can be provided, allowing the rotating support platform 43 to be locked when it rotates to other angles. The number of locking notches 425 is not limited here. A sensor 45 is provided on the lifting plate 41, and a sensor 423 is provided on the rotating seat 422 to cooperate with the sensor 45 to sense signals. The sensor 45 senses the rotation signal of the rotating seat 422. When the rotating seat 422 rotates to the position, the locking cylinder 441 extends and inserts the locking block 442 into the locking notch 425 to lock the angle of the rotating support platform 43.

[0041] The upper surface of the rotating base 422 is provided with a contour mounting groove 428. During installation, the middle of the rotating arm 431 is placed and positioned into the contour mounting groove 428, and then locked with several bolts 427. The contour mounting groove 428 facilitates the positioning of the rotating arm 431 and also limits its forward and backward movement, reducing the difficulty of installation and improving the reliability between the rotating arm 431 and the rotating base 422. The two ends of the rotating arm 431 extend to the left and right sides of the rotating base 422. When the rotating arm 431 rotates, it can rotate freely within a 360° range with the rotating base 422 as the center, making it convenient for workers to clean stains on any part of the photovoltaic module. Support members 432 are provided on both sides of the rotating arm 431. The support members 432 at both ends of the rotating arm 431 jointly support the photovoltaic module, ensuring the stability of the photovoltaic module support.

[0042] The longitudinal cross-sectional shape of the rotating arm 431 can be square, circular, or other polygonal. Correspondingly, the shape of the contour mounting groove 428 can be contoured to match the longitudinal cross-sectional shape of the rotating arm 431, and there are no restrictions here. The shape of the rotating arm 431 is preferably square, which facilitates the front and rear positioning of the rotating arm 431 and can improve the reliability between the rotating arm 431 and the rotating seat 422.

[0043] The support component 432 is a support plate or several support rods fixed on the rotating arm 431, or other support structures. This is set according to the actual situation, as long as it can support the photovoltaic module.

[0044] When using the highly reliable photovoltaic module conveying device 100 with rotating function provided in this solution, after the photovoltaic module is conveyed to its position via the module conveyor line 2, the lifting drive component 31 drives the lifting rod 32 to rise, pushing the rotating shaft 421 and thus causing the lifting plate 41 to move upward to the set height. This allows the support component 432 to lift the photovoltaic module upward. Operators can then check the cleanliness of certain areas of the photovoltaic module surface within their reach. If stains are found, they can be wiped with a cleaning cloth. The rotating support platform 43 can be manually pushed, allowing the photovoltaic module to rotate freely within a 360° range. Manual cleaning is performed on any part of the photovoltaic module. After the area is inspected and cleaned, the direction of the photovoltaic module in the subsequent work station needs to be rotated 180° around the vertical axis or kept in the initial direction. Therefore, the rotating support platform 43 is rotated to an angle of 180° or 360°. After the sensor 45 senses that the rotating support platform 43 has rotated into place, the locking cylinder 441 actively drives the locking block 442 to extend and lock the angle position of the rotating support platform 43. Then, the lifting drive component 31 drives the lifting rod 32 to descend, and the photovoltaic module falls back onto the module conveyor line 2 and is transported to the subsequent work station, completing the cleaning action of the photovoltaic module.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
