Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a photovoltaic component rotation reversing device. Background Art

[0002] Photovoltaic modules are devices used to convert sunlight into electricity. They are typically assembled from photovoltaic panels and frames. Translational conveying mechanisms are frequently used during the manufacturing process. Because photovoltaic panels typically have long and short sides, the frames are also distinguished during assembly. Transportation may require the panels or modules to be rotated.

[0003] Chinese patent CN 113335845A discloses a heavy-duty rotary conveying mechanism, comprising a fixed seat, a rotating base, a rotary reducer, a rotating frame, and a first conveying mechanism. The first conveying mechanism is used to convey products. The rotary reducer can allow the rotating frame to rotate around a vertical axis above the rotating base, thereby controlling the conveying direction of the first conveying mechanism. The first conveying mechanism also includes a pallet guide device, which includes a plurality of guide wheels and a mounting seat. The plurality of guide wheels are evenly distributed along the length of the mounting seat and are rotatably arranged on the top surface of the mounting seat. However, the guide wheels here cannot hinder the movement of the product along the conveying direction of the first conveying mechanism, so this conveying mechanism is suitable for products with smaller dimensions and a length significantly greater than the width. If the product is large, the center of gravity is likely to deviate from the center of rotation. Once the rotation speed is fast, the product may slip and become dangerous.

[0004] Therefore, it is necessary to improve the rotary reversing device to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a photovoltaic component rotation reversing device, which can use the front roller and the rear roller to clamp and center the photovoltaic panel, so that the photovoltaic panel will not fall off the conveying mechanism due to sliding during rotation.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions: a photovoltaic component rotation and reversing device, comprising a fixed bracket, a conveying mechanism located above the fixed bracket, and a rotating mechanism that drives the conveying mechanism to rotate around a vertical axis relative to the fixed bracket. The conveying mechanism is also provided with a correction mechanism, and the correction mechanism comprises a front blocking assembly arranged on the discharge side of the conveying mechanism and a rear blocking assembly arranged on the feed side of the conveying mechanism. At least one of the front blocking assembly and the rear blocking assembly is two, each front blocking assembly comprises a front roller and a front lifting cylinder that drives the front roller to rise and fall, and each rear blocking assembly comprises a rear roller, a rear lifting cylinder that drives the rear roller to rise and fall, and a correction cylinder that drives the rear lifting cylinder to move along the conveying direction of the conveying mechanism.

[0007] Specifically, the conveying mechanism includes a rotating bracket and a synchronous belt line arranged in the middle of the rotating bracket.

[0008] Furthermore, the rotating bracket is provided with a plurality of rollers in pairs on both sides of the conveying direction of the synchronous belt line, and the highest point of the rollers is 0-2 mm lower than the conveying surface of the synchronous belt line.

[0009] Furthermore, the rotating mechanism includes a slewing bearing, a servo motor, a reducer and a transmission gear. The slewing bearing is fixed to the upper part of the fixed bracket, the reducer is fixed on the rotating bracket, and the servo motor drives the transmission gear to rotate around the vertical axis through the reducer. The transmission gear is located below the fixed bracket and engages with the slewing bearing.

[0010] The beneficial effects of the technical solution of this utility model are:

[0011] When the photovoltaic panel is fed along a synchronous belt line, the rear rollers of this rotary reversing device lower below the conveyor surface, clearing the feed path. However, the front rollers rise first. The two front rollers determine the final resting position of the photovoltaic panel. Once the panel contacts the two front rollers, the rear rollers rise again and cooperate with the front rollers to clamp the panel. This prevents the panel from moving forward or backward along the conveyor, preventing it from sliding and falling off the conveyor as it rotates. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below with reference to specific embodiments.

[0024] Example:

[0025] like Figure 1 As shown, a photovoltaic module rotation reversing device 1 of the present invention includes a fixed bracket 11, a conveying mechanism 12 located above the fixed bracket 11, a rotating mechanism 13 driving the conveying mechanism 12 to rotate around a vertical axis relative to the fixed bracket 11, and a correction mechanism 14 is also provided on the conveying mechanism 12.

[0026] like Figure 2 As shown, the conveying mechanism 12 includes a rotating bracket 121 and a synchronous belt line 122 arranged on the upper part of the rotating bracket 121. The rotating bracket 121 is provided with a plurality of rollers 123 on both sides of the conveying direction of the synchronous belt line 122. The highest point of the roller 123 is 0-2 mm lower than the conveying surface of the synchronous belt line 122.

[0027] The conveyor mechanism 12 relies on a synchronous belt line 122 to transport the photovoltaic panels 2. The synchronous belt line 122 provides the power for transporting the panels 2. If the panels 2 are large in the left-right direction of transport, rollers 123 can extend the support width. When the rollers 123 contact the lower surface of the panel 2, they will follow the movement, preventing the sides of the panel 2 from sagging and causing a panel explosion. The rollers 123 also help prevent the panel 2 from tipping over due to a narrow support area.

[0028] like Figure 4 As shown, the correction mechanism 14 includes a pair of front blocking assemblies 141 arranged side by side on the discharge side of the conveying mechanism 12 and a pair of rear blocking assemblies 142 arranged side by side on the feed side of the conveying mechanism, each front blocking assembly 141 includes a front roller 1411 and a front lifting cylinder 1412 for driving the front roller 1411 to rise and fall, and each rear blocking assembly 142 includes a rear roller 1421, a rear lifting cylinder 1422 for driving the rear roller 1421 to rise and fall, and a correction cylinder 1423 for driving the rear lifting cylinder 1422 to move along the conveying direction of the conveying mechanism 12.

[0029] The conveying surface of the synchronous belt line 122 is highly stable, and the front lifting cylinder 1412 is used to control the front roller 1411 to switch between being above and below the conveying surface. Similarly, the rear lifting cylinder 1422 will control the rear roller 1421 to switch between being above and below the conveying surface. The return cylinder 1423 is used to control the front roller 1411 to move closer to or away from the rear roller 1421. The initial distance between the front roller 1411 and the rear roller 1421 in the front-to-back direction is greater than the dimension of the photovoltaic panel 2 in the front-to-back direction. When the synchronous belt line 123 is feeding, the rear roller 1421 drops below the conveying surface to make way for the feeding path, but the front roller 1411 will rise first. The two front rollers 1411 determine the final resting position of the photovoltaic panel 2. After the photovoltaic panel 2 contacts the two front rollers 1411, the rear roller 1421 rises and cooperates with the front rollers 1411 to clamp the photovoltaic panel 2. This prevents the photovoltaic panel 2 from moving forward and backward along the conveying direction. Therefore, when the conveying mechanism 12 rotates, the photovoltaic panel 2 will not slide and fall off the conveying mechanism 12. In actual applications, it is also possible to have two front blocking assemblies 141 and one rear blocking assembly 142, or one front blocking assembly 141 and two rear blocking assemblies 142. As long as the two side-by-side blocking assemblies can determine the position of one edge of the photovoltaic panel 2, the front-to-back position and angle of the photovoltaic panel 2 can be stabilized after clamping.

[0030] like Figure 3 As shown, the rotating mechanism 13 includes a slewing support 131, a servo motor 132, a reducer 133 and a transmission gear 134. The slewing support 131 is fixed to the upper part of the fixed bracket 11, the reducer 133 is fixed to the inner side of the conveying mechanism 12, the servo motor 132 is axially horizontal, and the servo motor 132 drives the transmission gear 134 to rotate around the vertical axis through the reducer 133. The transmission gear 134 is engaged with the slewing support 131. The highest point of the rotating mechanism 13 is lower than the conveying surface of the conveying mechanism 12.

[0031] The servo motor 132 is positioned horizontally, allowing the rotating mechanism 13 to be completely concealed within the conveyor mechanism 12, resulting in a compact structure and low equipment height. The speed reducer 133 features low cost, precise control, and simple maintenance. It reduces the speed and increases the torque output by the servo motor 132, thereby enabling the transmission gear 134 to generate sufficient driving force to rotate the conveyor mechanism 12 and its load. The slewing bearing 131 supports the conveyor mechanism 12 and, by cooperating with the transmission gear 134, enables the conveyor mechanism 12 to rotate about its vertical axis. This provides excellent load-bearing capacity, high transmission efficiency, and relatively low cost.

[0032] The working process of this equipment is:

[0033] 1. The feeding side of the synchronous belt line 122 faces the incoming material direction, and the photovoltaic panel 2 moves forward along the synchronous belt line 122 until it hits the two raised front rollers 1411;

[0034] 2. When the photovoltaic panel 2 completely passes over the rear roller 1421, the rear roller 1421 rises and then moves forward along the conveying direction. The rear roller 1421 and the front roller 1411 clamp and center the photovoltaic panel 2;

[0035] 3. The servo motor 132 starts to rotate. Under the reaction force of the slewing bearing 131 on the transmission gear 134, the conveying mechanism 12 rotates 90 degrees, so that the feeding side of the synchronous belt line 122 is aligned with the discharging direction, and the servo motor 132 stops.

[0036] 4. The rear roller 1421 is reset, and the synchronous belt line 122 is reversed, so that the photovoltaic panel 2 is sent out in the other direction of 90° from the feeding direction;

[0037] 5. If the photovoltaic panel 2 does not need to turn during the conveying process, the front roller 1411 descends, and the synchronous belt line 122 directly sends the photovoltaic panel 2 to the discharge side.

[0038] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
