Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, and in particular relates to a rotary conveying mechanism. [Background Technology]

[0002] Photovoltaic modules are generally rectangular plate structures. On the photovoltaic module production line, photovoltaic modules sometimes need to be transported horizontally, sometimes vertically, and sometimes the direction needs to be adjusted left and right or front and back. That is, when photovoltaic modules are transported, the angle of the photovoltaic modules needs to be rotated. If this is done manually, it will waste manpower and the production efficiency will be low.

[0003] To achieve automated conveying, a rotary conveying mechanism is designed. For example, Chinese Patent Publication No. CN222312008U discloses a rotary conveying mechanism for liquid crystal panels, which includes a conveying component and a reversing component. The conveying component has at least two parallel conveying shafts, and the material to be conveyed is mounted on multiple conveying shafts, transporting the material along a first direction. The reversing component includes a mounting plate and a reversing drive device that drives the mounting plate to move. The reversing drive device includes a lifting part and a rotating part. In this design, the rotating part can drive the mounting plate to rotate, thereby realizing the reversing action of the photovoltaic module. The rotating part includes a rotator directly connected to the mounting plate and driving the mounting plate to rotate. The rotator uses a servo motor. Therefore, in this design, the servo motor directly drives the mounting plate to rotate, and the servo motor drives the mounting plate and the photovoltaic module to rotate to a set angle. Furthermore, photovoltaic (PV) modules are relatively large in size and weight. They are attached to a mounting plate via vacuum adsorption, and both the PV module and the mounting plate tend to rotate in opposite directions. On one hand, the rotation angle of the PV module will shift, affecting subsequent power delivery. On the other hand, since the output shaft of the servo motor is directly connected to the mounting plate, the reverse rotation of the PV module will cause the servo motor's output shaft to also tend to rotate in the opposite direction. When the load attempts to rotate in the opposite direction, the servo motor may need to output greater torque to maintain direction, leading to increased current, potentially exceeding the rated value and causing coil overheating. This can result in internal coil heating and aging of the enameled wire within the servo motor. Moreover, the reverse torque will cause changes in the servo motor's speed, and the change in back electromotive force caused by the reverse rotation will affect the motor's electrical performance, increasing energy consumption and heat generation, and reducing the servo motor's lifespan.

[0004] Therefore, it is necessary to provide a rotary conveying mechanism to solve the above-mentioned technical problems. [Utility Model Content]

[0005] The main purpose of this utility model is to provide a rotary conveying mechanism that can prevent the photovoltaic module from reversing after rotating at a set angle, prevent the photovoltaic module from shifting at an angle after rotation, and prevent the quality problems caused by debris sticking to the photovoltaic module.

[0006] This utility model achieves the above objective through the following technical solution: a rotary conveying mechanism, comprising:

[0007] A conveying unit for conveying photovoltaic modules includes several conveying wheel shafts arranged in parallel and a rotary drive module that drives the several conveying wheel shafts to rotate simultaneously. Several conveying wheels for conveying photovoltaic modules are coaxially arranged on each of the conveying wheel shafts.

[0008] A rotating unit, used to lift the photovoltaic module on the conveying unit and rotate the photovoltaic module, includes a lifting drive, a lifting plate driven by the lifting drive, and a rotating support module rotatably mounted on the lifting plate to support the photovoltaic module. The lifting plate is provided with a drive module that drives the rotating support module to rotate around a vertical axis and an angle locking module that locks the rotation angle of the rotating support module.

[0009] Furthermore, the rotating support module includes a first rotating shaft rotatably mounted on the lifting plate, a rotating seat mounted on the first rotating shaft, and a rotating support platform fixed to the top of the rotating seat and extending outwards to support the photovoltaic module.

[0010] Furthermore, the rotating support platform includes a mounting plate disposed on the top of the rotating seat, a support frame disposed on the mounting plate, and a support component disposed on the top of the support frame. The support component is provided with a plurality of adsorption holes, and a gas channel for communicating with a negative pressure device is formed between the support frame and the support component. All the adsorption holes are in communication with the gas channel.

[0011] 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. The angle locking module includes a locking cylinder and a locking block that is driven by the locking cylinder to move horizontally and then extends into the locking notch to lock the rotating seat.

[0012] Furthermore, a sensor is provided on the lifting plate, and a sensing element is provided on the rotating base to cooperate with the sensor for signal sensing.

[0013] Furthermore, the drive module includes a first drive member disposed on the lifting plate, a movable frame driven by the first drive member to move closer to or away from the rotating seat, and a drive assembly disposed on the movable frame and driving the rotating seat to rotate about a vertical axis.

[0014] Furthermore, the drive assembly includes a first motor mounted on the movable frame, a second rotating shaft driven by the first motor to rotate about a vertical axis, and a drive wheel fixed to the top of the second rotating shaft and cooperating with the rotating seat for transmission.

[0015] Furthermore, two conveying units are symmetrically arranged front and rear, and the conveying height and conveying direction of the two conveying units are consistent. A first clearance space is formed between the two conveying units to avoid the rotating support module. A second clearance space is formed in the middle of each conveying unit to avoid the rotating support module. A first auxiliary support wheel for supporting the photovoltaic module is provided in the first clearance space, and a second auxiliary support wheel for supporting the photovoltaic module is provided in the second clearance space.

[0016] Furthermore, the rotary drive module includes a drive shaft disposed at one end of the conveyor wheel shaft and perpendicular to the conveyor wheel shaft, and a drive assembly for driving the drive shaft to rotate. The drive shaft is provided with a plurality of drive wheels, and one end of the conveyor wheel shaft is provided with a driven wheel that cooperates with the drive wheels for transmission.

[0017] Furthermore, the drive assembly includes a second motor, a drive shaft driven by the second motor to rotate around a vertical axis, and a drive gear disposed at the end of the drive shaft. A driven gear that meshes with the drive gear is disposed on the drive shaft.

[0018] Compared with the prior art, the beneficial effects of the rotary conveying mechanism of this utility model are as follows:

[0019] (1) The drive module is set to approach the rotating support module and drive the rotating support module to rotate by a set angle. The angle locking module locks the angle of the rotating support module. That is, the locking cylinder drives the locking block to extend into the locking notch to lock the rotating seat, thereby locking the angle position of the rotating support module. This can prevent the photovoltaic module from reversing after rotating by a set angle, and also prevent the photovoltaic module from shifting at an angle after rotation.

[0020] (2) The drive module and the rotating support module are set up separately and independently. When the rotating support module needs to rotate, the first drive component of the drive module drives the moving frame to move the drive assembly closer to the rotating seat. The first motor drives the second rotating shaft to rotate the drive wheel. The drive wheel drives the rotating seat and rotates the rotating support module by a set angle. After the photovoltaic module has rotated, the first drive component of the drive module drives the moving frame to move the drive assembly away from the rotating seat. That is, the drive assembly and the rotating support module are set up separately. This will not cause the output shaft of the first motor to reverse. This can solve the problem of short life of the servo motor caused by the reverse rotation of the photovoltaic module in the prior art.

[0021] (3) The conveying unit uses a conveying wheel to convey photovoltaic modules. The conveying wheel is disc-shaped and thin. The contact surface between the conveying wheel and the photovoltaic module is close to line contact. It is difficult for debris to adhere to the conveying surface of the conveying wheel. That is, it is difficult for debris to be transferred to the photovoltaic module through the conveying wheel. Therefore, using the conveying wheel provided in this solution to convey photovoltaic modules can avoid the quality problems caused by debris sticking to the photovoltaic module and improve the quality of the photovoltaic module.

Detailed Implementation Methods

[0035] Please refer to Figures 1-8 This embodiment is a rotary conveying mechanism 100, which includes:

[0036] The conveying unit 1 is used to convey photovoltaic modules. It includes a plurality of conveying wheel shafts 11 arranged in parallel and a rotary drive module 12 that drives the plurality of conveying wheel shafts 11 to rotate simultaneously. Each conveying wheel shaft 11 is coaxially provided with a plurality of conveying wheels 13 for conveying photovoltaic modules.

[0037] The rotating unit 3 is used to lift the photovoltaic module on the conveying unit 1 and rotate the photovoltaic module. It includes a lifting drive 31, a lifting plate 32 driven by the lifting drive 31 to perform lifting and lowering actions, and a rotating support module 33 rotatably mounted on the lifting plate 32 to support the photovoltaic module. The lifting plate 32 is provided with a drive module 34 that drives the rotating support module 33 to rotate around a vertical axis and an angle locking module 35 that locks the rotation angle of the rotating support module 33.

[0038] The lifting drive component 31 is mounted on the frame 2. In this embodiment, the lifting plate 32 is rectangular; therefore, two lifting drive components 31 are arranged on the left and right sides, respectively, on the two short sides of the lifting plate 32, to facilitate the stability of the lifting movement of the lifting plate 32. In other embodiments, the number and installation position of the lifting drive components 31 can be set according to the design. In this embodiment, the lifting drive component 31 is set as a cylinder, but it can also be set as a servo motor, which can be adjusted according to the actual application and is not limited here. To further ensure the stability of the lifting movement of the lifting plate 32, several guide rods 36 are movably mounted on the frame 2. The guide rods 36 are all mounted on the frame 2 through linear bearings 37, and the top ends of the guide rods 36 are fixed to the lifting plate 32. The use of linear bearings 37 can ensure the stability of the lifting movement of the lifting plate 32.

[0039] The rotating support module 33 includes a first rotating shaft 331 rotatably mounted on the lifting plate 32, a rotating seat 332 mounted on the first rotating shaft 331, and a rotating support platform 334 fixed to the top of the rotating seat 332 and extending outwards to support the photovoltaic module.

[0040] A plurality of first bearings are fitted around the outer periphery of the first rotating shaft 331. A first bearing sleeve 336 is mounted on the lifting plate 32 via a plurality of screws. The first rotating shaft 331 is rotatably mounted within the first bearing sleeve 336 via the first bearings, thereby rotatably mounting the first rotating shaft 331 on the frame 2. A limiting member 337 is fitted around the bottom outer periphery of the first rotating shaft 331. The limiting member 337 abuts against the inner ring of the lower first bearing, limiting the first rotating shaft 331 and preventing it from moving upward. The first rotating shaft 331 is a stepped shaft, and its shoulder abuts against the inner ring of the upper first bearing, limiting the first rotating shaft 331 and preventing it from moving downward.

[0041] The rotating support platform 334 is fixed to the top of the rotating base 332 by several screws. The rotating support platform 334 includes a mounting plate 3343 on the top of the rotating base 332, a support frame 3341 on the mounting plate 3343, and a support component 3342 on the top of the support frame 3341. The upper surfaces of the support component 3342 are all on the same plane and contact the photovoltaic module during rotation. The support frame 3341 is made of metal profile and can support photovoltaic modules of different weights, ensuring the stability of the rotating support platform 334. To prevent the support component 3342 from scratching the photovoltaic module, the support component 3342 can be made of silicone or other plastic materials; the material of the support component 3342 is not limited here. To ensure close contact between the photovoltaic module and the support component 3342 and prevent the photovoltaic module from sliding, the support component 3342 is provided with several adsorption holes 3344. A gas channel is formed between the support frame 3341 and the support component 3342, which is connected to a negative pressure device (not shown in the figure). The adsorption holes 3344 are all connected to the gas channel, and under the action of the negative pressure device (not shown in the figure), the support component 3342 adsorbs the photovoltaic module, preventing the photovoltaic module from sliding relative to the rotating support platform 334 during rotation.

[0042] In this embodiment, the support frame 3341 includes a first profile and a second profile extending horizontally and arranged parallel to each other front to back. Two third profiles extend forward from the first profile, and two fourth profiles extend backward from the second profile. Each profile has a support component 3342 at its upper end that contacts the photovoltaic module. The first, second, third, and fourth profiles together form a cross-shaped structure, which increases the support area and ensures the stability of the support. In other embodiments, the structure of the support frame 3341 can be set according to actual conditions and can be a rectangular frame or other structures. The specific structure of the support frame 3341 is not limited here.

[0043] The outer periphery of the rotating base 332 is provided with several locking notches 3321. Angle locking modules 35 are provided in pairs and symmetrically arranged on the front and rear sides of the rotating base 332. Each angle locking module 35 includes a locking cylinder 351 and a locking block 352 driven by the locking cylinder 351 to move horizontally and extend into the locking notches 3321 to lock the rotating base 332. In this embodiment, four locking notches 3321 are provided. When the rotating support module 33 rotates 90°, 180°, 270°, or 360°, the rotating support platform 43 can be locked. In other embodiments, other numbers of locking notches 3321 can be provided, allowing the rotating support module 33 to be locked when rotated to other angles. The number of locking notches 3321 is set according to the actual angle of rotation and is not limited here. A sensor 38 is installed on the lifting plate 32, and a sensor 39 is installed on the rotating seat 332 to sense signals in conjunction with the sensor 38. The sensor 38 senses the rotation signal of the rotating seat 332. When the rotating seat 332 rotates to the correct position, the locking cylinder 351 extends and inserts the locking block 352 into the locking notch 3321 to lock the angle of the rotating support module 33. The drive module 34 can approach the rotating support module 33 and drive the rotating support module 33 to rotate by a set angle. The angle locking module 35 locks the angle of the rotating support module 33. That is, the locking cylinder 351 drives the locking block 352 to extend into the locking notch 3321 to lock the rotating seat 332, thereby locking the angle position of the rotating support module 33. This can prevent the photovoltaic module from reversing after rotating by a set angle, and can also prevent the photovoltaic module from shifting its angle after rotation.

[0044] The drive module 34 includes a first drive member 341 mounted on the lifting plate 32, a movable frame 342 driven by the first drive member 341 to move closer to or away from the rotating seat 332, and a drive assembly 343 mounted on the movable frame 342 that drives the rotating seat 332 to rotate around a vertical axis. The first drive member 341 can be a cylinder or a servo motor, depending on the actual situation, and is not limited here. The drive assembly 343 includes a first motor 3431 mounted on the movable frame 342, a second rotating shaft 3432 driven by the first motor 3431 to rotate around a vertical axis, and a drive wheel 3433 fixed to the top of the second rotating shaft 3432 and cooperating with the rotating seat 332 for transmission. The second rotating shaft 3432 is rotatably mounted on the movable frame 342 via a second bearing. The movable frame 342 is movably mounted on the lifting plate 32 via a slide rail slider, and the lifting plate 32 is provided with a clearance opening 321 to avoid the drive assembly 343. The drive module 34 and the rotating support module 33 are set separately and independently. When the rotating support module 33 needs to rotate, the first drive component 341 of the drive module 34 drives the moving frame 342 to move the drive assembly 343 closer to the rotating seat 332. The first motor 3431 drives the second rotating shaft 3432 to rotate the drive wheel 3433. The drive wheel 3433 drives the rotating seat 332 and the rotating support module 33 to rotate by a set angle. After the photovoltaic module has rotated, the first drive component 341 of the drive module 34 drives the moving frame 342 to move the drive assembly 343 away from the rotating seat 332. That is, the drive assembly 343 and the rotating support module 33 are set separately, which will not cause the output shaft of the first motor 3431 to have a tendency to reverse. This can solve the problem of short life of servo motor caused by photovoltaic module reversal in the prior art.

[0045] In this embodiment, two conveying units 1 are symmetrically arranged front and rear. The conveying height and conveying direction of the two conveying units 1 are consistent. A first clearance space 15 is formed between the two conveying units 1 to avoid the rotating support module 33. The first profile and the second profile will move within the first clearance space 15. A first auxiliary support wheel 17 supporting the photovoltaic module is provided at the first clearance space 15 and between the first profile and the second profile to prevent the photovoltaic module at the first clearance space 15 from sagging. Each of the two conveying units 1 includes a plurality of parallel conveying wheel shafts 11 and a rotating drive module 12 that drives the plurality of conveying wheel shafts 11 to rotate simultaneously. A plurality of conveying wheels 13 for conveying photovoltaic modules are coaxially arranged on each conveying wheel shaft 11. A second clearance space 16 is formed in the middle of each conveying unit 1 to avoid the rotating support module 33. The distance between two adjacent conveying wheel shafts 11 in the middle is greater than the distance between two adjacent conveying wheel shafts 11 in other positions, thus forming the second clearance space 16. The third profile and the fourth profile will move within the second clearance space 16. A second auxiliary support wheel 18 is provided at the second clearance space 16 and between the third profile and the fourth profile to support the photovoltaic module, which can prevent the photovoltaic module at the second clearance space 16 from sagging.

[0046] Both the front end of the conveyor wheel axle 11 of the front conveyor unit 1 and the rear end of the conveyor wheel axle 11 of the rear conveyor unit are equipped with side guard wheels 14 to prevent the photovoltaic modules from shifting position. The two conveyor units 1 together convey the photovoltaic modules, and the two side guard wheels 14 can limit and correct the front and rear sides of the photovoltaic modules to prevent the photovoltaic modules from shifting position during transportation. The side guard wheels 14 can be made of plastic or rubber to avoid scratching the photovoltaic modules, or other materials. The material of the side guard wheels 14 is not limited here.

[0047] The rotary drive module 12 includes a drive shaft 121 disposed at one end of the conveyor wheel shaft 11 and perpendicular to the conveyor wheel shaft 11, and a drive assembly 122 for driving the drive shaft 121 to rotate. The drive shaft 121 has several driving wheels 123, and one end of the conveyor wheel shaft 11 has a driven wheel 124 that cooperates with the driving wheels 123 for transmission. Both the conveyor wheel shaft 11 and the drive shaft 121 are rotatably mounted on the frame 2 via bearings. The several driving wheels 123 on the drive shaft 121 and the several driven wheels 124 at the ends of the conveyor wheel shafts 11 cooperate one-to-one for transmission. Rotation of the drive shaft 121 can drive the several conveyor wheel shafts 11 to rotate simultaneously.

[0048] The drive assembly 122 includes a second motor 1221, a drive shaft 1222 driven by the second motor 1221 to rotate around a vertical axis, and a drive gear 1223 disposed at the end of the drive shaft 1222. A driven gear 1224 meshes with the drive gear 1223 on the drive shaft 121. When the second motor 1221 operates, it causes the drive shaft 1222 to drive the drive gear 1223 to rotate. The drive gear 1223 meshes with the driven gear 1224, thereby driving the drive shaft 121 to rotate. A plurality of driving wheels 123 on the drive shaft 121 correspond one-to-one with the driven wheels 124 at the ends of a plurality of conveyor wheel shafts 11, thereby driving the plurality of conveyor wheel shafts 11 to rotate simultaneously. The rotation of the plurality of conveyor wheel shafts 11 drives the rotation of a plurality of conveyor wheels 13 to achieve the conveying of photovoltaic modules.

[0049] To ensure low operating noise and high transmission torque, the driving gear 1223 and driven gear 1224 of the meshing transmission are made of different materials: one is plastic and the other is metal. Transmission occurs through the combination of metal and plastic, which provides good self-lubrication, increases transmission torque, and reduces operating noise. The driving gear 123 and driven gear 124 of the meshing transmission are both gear drives. The pair of driving and driven gears 123 and 124 in the meshing transmission are also made of different materials: one is plastic and the other is metal. Transmission occurs through the combination of metal and plastic, which provides good self-lubrication, increases transmission torque, and reduces operating noise.

[0050] In this embodiment, for ease of manufacturing, the driven gear 1224 and the driving wheel 123 on the transmission shaft 121 are made of the same material, both being metal, while the driving gear 1223 and the driven wheel 124 are made of plastic. In other embodiments, the materials of the driven gear 1224 and the driving wheel 123 can be adjusted according to actual conditions. No restrictions are imposed here, as long as a metal-plastic transmission method can be achieved.

[0051] In other embodiments, both the driving wheel 123 and the driven wheel 124 that cooperate in the transmission are provided with magnetic wheels, and the two magnetic wheels cooperate in the transmission.

[0052] The conveyor wheel 13 is disc-shaped and relatively thin. The conveyor wheel 13 uses its outer periphery to convey photovoltaic modules, and the thickness of the conveyor wheel 13 gradually decreases from the center to the outer periphery. Because the outer periphery of the conveyor wheel 13 is very thin, the contact surface between the conveyor wheel 13 and the photovoltaic module is close to line contact. It is difficult for debris to adhere to the conveying surface of the conveyor wheel 13. That is, it is difficult for debris to be transferred to the photovoltaic module through the conveyor wheel 13. Therefore, using the conveyor wheel 13 provided in this solution to convey photovoltaic modules can avoid quality problems caused by debris sticking to the photovoltaic module and can improve the quality of the photovoltaic module.

[0053] The conveying unit 1 is equipped with a photoelectric sensor to detect whether the photovoltaic module has been conveyed to the correct position. To prevent environmental debris from falling onto the photovoltaic module, conveying unit 1, or rotating unit 3, the rotating conveying mechanism 100 also includes a fan and a filter. The fan and filter work together to achieve a cleanliness level of 1000, meeting the cleanliness requirements of the module and improving the cleanliness of the rotating conveying mechanism 100. This prevents quality problems caused by debris adhering to the photovoltaic module and improves the quality of the photovoltaic module. The number and installation position of the fan and filter are not limited in this embodiment and can be adjusted according to actual conditions. Since the photovoltaic module production process involves heating that melts the adhesive, the surface temperature of the photovoltaic module will rise. The fan blows air onto the surface of the photovoltaic module, which can reduce the surface temperature of the photovoltaic module and prevent the components on the rotating conveying mechanism 100 from overheating, thus improving the service life of the rotating conveying mechanism 100.

[0054] When the rotary conveying mechanism 100 provided in this solution is applied, the front and rear conveying units 1 jointly convey photovoltaic modules. After the photoelectric sensor detects that the photovoltaic modules have been conveyed to the correct position, the front and rear conveying units 1 stop conveying. The lifting drive 31 drives the lifting plate 32 to rise to a set height, so that the rotating support platform 334 lifts the photovoltaic modules upward and away from the conveying unit 1. The first drive 341 drives the moving frame 342 to approach the rotating seat 332. At this time, the drive wheel 3433 contacts and engages with the rotating seat 332. Simultaneously, the first motor 3431 drives the second rotating shaft 3432 to rotate the drive wheel 3433. The drive wheel 3433 drives the rotating seat 332 to rotate by a set angle, i.e., rotates... The rotating support module 33 and the rotating seat 332 rotate together at a set angle, such as 90°, 180°, 270° or 360°. After the sensor 38 senses that the rotating seat 332 has rotated to the correct position, the locking cylinder 351 drives the locking block 352 to extend and lock the angle position of the rotating support module 33. The first driving component 341 drives the moving frame 342 away from the rotating seat 332. The first motor 3431 stops driving the second rotating shaft 3432 to rotate. Then the lifting driving component 31 drives the lifting plate 32 to descend. The locking cylinder 351 of the angle locking module 35 drives the locking block 352 to retract. At the same time, the photovoltaic module falls back onto the front and rear conveying units 1 and is conveyed to the subsequent work station.

[0055] 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.
