[0056] Photovoltaic technology is a new energy technology that converts solar energy into electrical energy. With the continuous development of the photovoltaic industry, higher and higher requirements are put forward for the production efficiency of photovoltaic wafers. To improve the transfer efficiency, an automated handling mechanism is often used in the photovoltaic production line to achieve material handling between different workstations.

[0057] In the prior art, the handling mechanism is often a conveyor belt structure, and the longest handling distance of the material is the length of the conveyor belt. There are often multiple process chambers for processing on the photovoltaic production line, and the substrate needs to enter different process chambers for process treatments such as coating. Therefore, if a conveyor belt transmission structure is adopted, structures such as conveyor belts and conveyor belt racks need to be fixedly arranged in each process chamber, which will cause the volume of each process chamber to be relatively large, resulting in a relatively large floor space for the entire photovoltaic production line.

[0058] In the first aspect of the embodiments of the present application, a handling mechanism is proposed. The handling mechanism includes a base 100, a first sliding member 200, a carrying assembly 300, and a transmission member 400, as Figure 1 and Figure 2As shown, the base 100 includes two first mounting seats 120 which are respectively arranged on both sides of the base 100 along the second direction. On two opposite side surfaces of the first mounting seat 120, first racks 110 are respectively arranged, and both the first mounting seat 120 and the first racks 110 extend along the first direction. The first slider 200 is slidably connected to the base 100. As Figure 2 , Figure 5 and Figure 6 shown, on both sides of the first slider 200 along the second direction, chutes are respectively arranged, and on the first mounting seat 120, slide rails are arranged. Thus, the first slider 200 can slide on the base 100 through the cooperation of the chutes and the slide rails. Both the chutes and the slide rails extend along the first direction. Thus, when the first slider 200 is driven, it can move relative to the base 100 along the first direction.

[0059] The carrying component 300 is used for carrying the material 800, and the material 800 can be a substrate or other workpieces. The carrying component 300 is slidably connected to the first slider 200. As Figures 4 to 6 shown, the carrying component 300 includes a second slider 310. The first slider 200 is provided with a chute, and on the lower wall of the second slider 310, a slide rail is arranged. Through the cooperation of the chute and the slide rail, when the second slider 310 is driven, it can move relative to the first slider 200 along the first direction, thereby driving the entire carrying component 300 and the carried material 800 to move. It should be noted that the carrying component 300 further includes two second racks 320. As Figure 2 shown, the second racks 320 extend along the first direction, and the two second racks 320 are respectively connected to two side walls of the second slider 310 along the second direction.

[0060] The transmission member 400 is fixedly connected to the first slider 200. When the first slider 200 moves on the base 100, the transmission member 400 can move accordingly. The transmission member 400 includes a first gear 410 and a second gear 420. Among them, the first gear 410 meshes with the first rack 110, and the second gear 420 meshes with the second rack 320. It should be noted that the first gear 410 and the second gear 420 can rotate synchronously. For example, as Figures 1 to 3 shown, the first gear 410 and the second gear 420 are arranged in sequence along the vertical direction. Both the first gear 410 and the second gear 420 are sleeved on the same transmission shaft 430 and can rotate synchronously with the transmission shaft 430. Thus, when either the first gear 410 or the second gear 420 rotates, it can drive the other to rotate through the transmission shaft 430. Or, in some other embodiments, the first gear 410 and the second gear 420 can also achieve synchronous rotation through the cooperation of other transmission structures such as a gear set.

[0061] When the first sliding member 200 moves relative to the base 100, the bearing assembly 300 moves relative to the base 100 along with the movement of the first sliding member 200. The bearing assembly 300 drives the first gear 410 to move relative to the first rack 110, so that the first gear 410 rotates during the movement and drives the second gear 420 to rotate synchronously. Since the second gear 420 is meshed with the second rack 320, the rotation of the second gear 420 drives the second rack 320 to move, thereby driving the bearing assembly 300 to extend or retract relative to the first sliding member 200.

[0062] It should be noted that the first rack 110 and the second rack 320 are respectively located on both sides of the transmission member 400, so that the first sliding member 200 and the bearing assembly 300 move in the same direction. That is, the bearing assembly 300 can move along with the first sliding member 200 relative to the base 100, and the bearing assembly 300 can also move in the same direction as the first sliding member 200 to extend further, and the bearing assembly 300 can extend or retract compared to the base 100, thereby having a larger conveying range.

[0063] As Figure 7 The embodiment shown is used as an example for explanation, wherein Figure 7 The upper figure is a schematic diagram of the transport mechanism in its initial state. Figure 7 The lower figure is a schematic diagram of the conveying mechanism in the extended state. When the conveying mechanism of the first aspect of the present application is applied to the photovoltaic production line of the third direction of the present application, there are process chambers 700 for coating, drying or other process treatments on the left and right sides of the conveying mechanism. When the material 800 is placed on the supporting assembly 300, the conveying mechanism can drive the first sliding member 200 to move to the left relative to the base 100 by means of a driving motor 510, an electric cylinder, a pneumatic cylinder, etc. At the same time, the supporting assembly 300 is driven to move to the left relative to the first sliding member 200 to further extend, and the supporting assembly 300 can move relative to the base 1 00 extends out and extends into the chamber on the left, waiting for the material 800 to be processed in the process chamber 700. It should be noted that "the process chamber 700 processes the material 800" may refer to taking the material 800 away for processing in the process chamber 700 through structures such as a robotic arm and a carrier table, so that the carrier assembly 300 can retract to its original position unloaded; or, in the process chamber 700, the material 800 on the carrier assembly 300 can be directly subjected to process treatments such as coating, and the carrier assembly 300 transports the material 800 back to its original position after the processing is completed. Thereafter, the carrier assembly 300 can also transport the material 800 to the chamber on the right for the next process treatment. It can be understood that the order of transporting left first and then right or right first and then left can be determined according to the specific process steps, or, in other embodiments, the transport mechanism only transports on one side.

[0064] Based on the above, it can be found that the carrying component 300 of the handling mechanism of the present application realizes two-stage telescoping, and can extend or retract relative to the base 100. Therefore, its conveying range is not limited to the length range of the base 100, and has a larger conveying range. The carrying component 300 can extend into the process chamber 700 of the process device for process treatments such as coating, without fixedly arranging transmission structures such as a conveyor belt 330 and a frame in the process chamber 700, avoiding the long-term occupation of the space in the process chamber 700, so that the spatial layout in the process chamber 700 can be optimized to further reduce the volume of the process device, and further reduce the floor area of the entire photovoltaic production line.

[0065] It can be understood that when coating treatment needs to be carried out in the process chamber, if the conveyor belt structure in the prior art is adopted, on the one hand, it will long-term occupy the space in the process chamber, causing the device to be bulky. On the other hand, since the conveyor belt is in the process chamber, it will be coated with a film layer. When the next substrate is placed on the conveyor belt, the film layer on the conveyor belt may adhere to the substrate, thus affecting the subsequent coating quality of the substrate. In the present application, by using the handling mechanism with such a telescoping structure, after the substrate is placed in the process chamber 700, the carrying component 300 of the handling mechanism can be retracted, and then the coating treatment can be carried out, thus avoiding the handling mechanism from being coated, ensuring the cleanliness of the handling mechanism, and reducing the risk of the substrate being contaminated during transportation.

[0066] In some embodiments, as Figure 1 , Figure 2 and Figure 6 shown, the first rack 110 is arranged inside the first mounting seat 120, the second rack 320 is arranged outside the second sliding member 310, and the transmission member 400 is arranged between the first mounting seat 120 and the first sliding member 200. Commutation is carried out through the racks on different sides of the gear, so that the moving directions of the first sliding member 200 and the carrying component 300 can be kept consistent. Moreover, by arranging the second rack 320 outside the second sliding member 310 and the first rack 110 inside the first mounting seat 120, in the projection along the vertical direction, the projection area of the first sliding member 200 is entirely within the projection area of the base 100, which helps to reduce the volume of the first sliding member 200, thereby reducing the load for the driving component 500 to drive the first sliding member 200 to move.

[0067] It can be understood that in other embodiments, the first rack 110 can also be arranged outside the base 100, the two sides of the second sliding member 310 are protruded with mounting seats, and the second rack 320 is arranged on the relative inner sides of the mounting seats, which can also realize the co-directional driving of the carrying component 300 and the first sliding member 200.

[0068] In some embodiments, the transmission member 400 further includes a transmission shaft 430, asFigures 3 to 6 As shown, both ends of the transmission shaft 430 are respectively connected to the first gear 410 and the second gear 420. The transmission member 400 further includes a second mounting seat 440, which is located between the first gear 410 and the second gear 420, and is respectively fixedly connected to the first sliding member 200 and rotatably connected to the transmission shaft 430, enabling the transmission member 400 to move synchronously with the first sliding member 200. The first gear 410 and the second gear 420 are respectively fixedly connected to the transmission shaft 430, that is, both the first gear 410 and the second gear 420 rotate synchronously with the transmission shaft 430, so as to transmit power to the second gear 420 when the first sliding member 200 is driven to move and drive the carrying assembly 300 to move in the same direction.

[0069] In some embodiments, the material 800 can be directly placed on the second sliding member 310, and the relative position between the material 800 and the second sliding member 310 does not change during the operation of the handling mechanism. In other embodiments, the carrying assembly 300 further includes a conveyor belt 330 to adjust the position of the material 800 on the carrying assembly 300. Specifically, as Figure 1 、 Figure 2 and Figure 7 shown, the conveyor belt 330 is arranged on the second sliding member 310 and can be wound around the second sliding member 310 and move relative to the second sliding member 310. The conveyor belt 330 is used to carry the material 800, and the material 800 can be directly placed on the conveyor belt 330. When the conveyor belt 330 moves, it can drive the material 800 to move relative to the second sliding member 310.

[0070] In some more specific embodiments, the carrying assembly 300 may further include a driving member (not shown in the figure), and the driving member is arranged on the second sliding member 310 and is used to drive the conveyor belt 330 to move so as to drive the material 800 to move.

[0071] In other specific embodiments, the conveyor belt 330 is driven by the relative movement of the first sliding member 200 and the second sliding member 310. Specifically, the conveyor belt 330 includes a first section 331 and a second section 333 arranged in parallel, and the first section 331 and the second section 333 are respectively located on the upper and lower sides of the second sliding member 310. It can be understood that when the conveyor belt 330 rotates, the moving directions of the first section 331 and the second section 333 are opposite.

[0072] The conveyor belt 330 further includes a connecting member 332, and the connecting member 332 is connected to the first section 331 and can be connected to the first sliding member 200 so that the first section 331 of the conveyor belt 330 is connected to the first sliding member 200. The connecting member 332 can be such as Figure 2 and Figure 9The shown splint structure enables the connecting member 332 to move synchronously with the first section 331, and then connects the connecting member 332 to the first sliding member 200; the connecting member 332 can also be a structure such as a screw, which is passed through the conveyor belt 330 and fixedly connected to the first sliding member 200, and the structure of the connecting member 332 is not specifically limited.

[0073] When the second sliding member 310 moves relative to the first sliding member 200, the conveyor belt 330 is driven to move by the movement of the second sliding member 310, and the moving direction of the second section 333 is the same as the moving direction of the second sliding member 310, so that the material 800 can be further moved along the moving direction of the second sliding member 310 under the drive of the conveyor belt 330, realizing the third-level telescoping.

[0074] Furthermore, as Figure 2 and Figure 8 shown, the bearing assembly 300 further includes two rollers 340, and the two rollers 340 are respectively arranged at both ends of the second sliding member 310. The conveyor belt 330 is wound around the second sliding member 310 and the rollers 340. The arrangement of the rollers 340 helps to reduce the frictional resistance when the conveyor belt 330 moves, so as to improve the transmission efficiency. As Figure 9 shown, the connecting member 332 includes a first connecting portion 3321 located inside the conveyor belt 330 and a second connecting portion 3322 located outside the conveyor belt 330. The first connecting portion 3321 and the second connecting portion 3322 are connected to clamp the conveyor belt 330.

[0075] Wherein, a first tooth portion (not shown in the figure) is arranged on the inner peripheral side of the conveyor belt 330, and the first tooth portions are evenly distributed on the inner peripheral side of the conveyor belt 330. A second tooth portion (not shown in the figure) is arranged on the outer peripheral side of the roller 340. The first tooth portion and the second tooth portion are engaged to reduce the probability of the conveyor belt 330 and the roller 340 slipping during transmission and improve the accuracy of the conveyor belt 330 transmission. Correspondingly, as Figure 9 shown, a third tooth portion 3323 is arranged on the side of the first connecting portion 3321 facing the conveyor belt 330. The third tooth portion 3323 can be engaged with the first tooth portion to limit the relative displacement between the connecting member 332 and the conveyor belt 330 and reduce the probability of slipping between the connecting member 332 and the conveyor belt 330, thereby improving the load capacity of the conveyor belt 330.

[0076] Alternatively, in some other embodiments, the conveyor belt 330 has a smooth surface structure. Correspondingly, there is no need to provide a convex tooth structure on the outer peripheral side of the roller 340. To achieve the connection and fixation of the conveyor belt 330 and the connecting member 332, at least one of the two opposite side surfaces of the first connecting portion 3321 and the second connecting portion 3322 is provided with a first groove (not shown in the figure), that is, the first connecting portion 3321 or the second connecting portion 3322 is provided with a first groove, or both the first connecting portion 3321 and the second connecting portion 3322 are provided with first grooves. When the first connecting portion 3321 and the second connecting portion 3322 are clamped together, the first groove forms a space for the conveyor belt 330 to pass through, and the groove wall of the first groove abuts against the conveyor belt 330, so that the conveyor belt 330 is clamped and connected by the first connecting portion 3321 and the second connecting portion 3322.

[0077] Taking the embodiments shown in Figure 1 、 Figure 2 and Figure 7 as an example, when the first slider 200 is driven to move leftward, the carrier assembly 300 moves leftward synchronously with the first slider 200, and the second slider 310 is driven by the second gear 420 to move further leftward relative to the first slider 200. Thus, a relative movement occurs between the first slider 200 and the second slider 310. It can be understood that the moving direction of the first slider 200 relative to the second slider 310 is rightward. Thus, the first slider 200 drives the first section 331 to move rightward through the connecting member 332. The moving direction of the second section 333 is opposite to that of the first section 331. Thus, the second section 333 carrying the material 800 moves leftward, realizing a further leftward movement of the material 800 relative to the second slider 310.

[0078] It can be understood that through this three-stage telescopic transmission structure, the handling mechanism obtains a larger transmission range, and the entire structure can be realized with only one driving source, with a relatively simple structure and low manufacturing cost.

[0079] Furthermore, it can be understood that when the conveyor belt 330 is too loose, the transmission efficiency is affected, and when the conveyor belt 330 is too tight, the service life of the conveyor belt 330 is affected. Therefore, it is necessary to ensure that the tightness of the conveyor belt 330 is within a suitable range. Furthermore, in this embodiment, a structure for facilitating the adjustment of the tightness of the conveyor belt 330 is also provided.

[0080] Specifically, as shown in Figure 1 、 Figure 8 and Figure 10As shown, mounting portions 311 connected to the rollers 340 are respectively provided at both ends of the second sliding member 310. An installation groove 312 extending in the first direction is formed in the mounting portion 311. Both ends of the roller shaft 341 of the roller 340 are respectively inserted into the installation grooves 312 on both sides to be mounted in the middle of the mounting portions 311 on both sides. A threaded member 342 is further connected to the mounting portion 311. The threaded member 342 is threadedly connected to the mounting portion 311, and its end abuts against the roller shaft 341. Thus, when the threaded member 342 rotates, its end can push the roller shaft 341 to move in the installation groove 312 to adjust the distance between the two rollers 340, thereby adjusting the tightness of the conveyor belt 330.

[0081] In some embodiments, the handling mechanism further includes a drive assembly 500. The drive assembly 500 includes a lead screw 520 and a drive motor 510. The lead screw 520 is passed through the threaded seat of the first sliding member 200 and is threadedly connected to the first sliding member 200. One end of the lead screw 520 is connected to the output shaft of the drive motor 510. Thus, the drive motor 510 can drive the lead screw 520 to rotate, and the rotation of the lead screw 520 can drive the first sliding member 200 to move.

[0082] Furthermore, as Figure 1 and Figure 2 shown, a straight bevel gear is provided at one end of the lead screw 520 connected to the output shaft of the drive motor 510. The output shaft of the drive motor 510 is arranged in the vertical direction, and a straight bevel gear is also provided on the output shaft. Thus, the two straight bevel gears mesh with each other to change the power output direction of the drive motor 510.

[0083] In a second aspect embodiment of the present application, a handling device is proposed. As Figure 11 shown, the handling device includes the handling mechanism mentioned in any of the above embodiments.

[0084] Furthermore, the handling device is further provided with a lifting mechanism 600. The lifting mechanism 600 is connected to the handling mechanism and is used to drive the handling mechanism to move in the vertical direction. In some embodiments, a structure such as a hydraulic cylinder or a cylinder that can withstand a large load can be directly used to drive the handling mechanism to move in the vertical direction. In the embodiments of the present application, the load of the handling mechanism is dispersed by multi-point support, and jacking is achieved through a first driving member 610.

[0085] Specifically, as Figure 12As shown, the lifting mechanism 600 includes a first driving member 610, a plurality of first rotating shafts 620, a plurality of second rotating shafts 630, two transfer members 640 and four lifting members 650, and the four lifting members 650 are respectively located at the four corners of the base 100 to disperse the load and provide stable support. The two transfer members 640 are respectively arranged on both sides of the first driving member 610 along the second direction, and are connected to the first driving member 610 through the first rotating shaft 620, so that the power output by the first driving member 610 is transmitted to the transfer member 640 through the first rotating shaft 620. The lifting members 650 are grouped in pairs, and each group of lifting members 650 is respectively arranged on both sides of a transfer member 640 along the first direction, and is connected to the transfer member 640 through the second rotating shaft 630, so that the power output by the first driving member 610 is transmitted to the lifting member 650 through the transfer member 640 and the second rotating shaft 630. That is, the first driving member 610 drives the first rotating shaft 620 and the second rotating shaft 630 to rotate in sequence, and the lifting member 650 can convert the rotation of the second rotating shaft 630 into a driving force in the up and down directions to drive the transport mechanism to rise or fall.

[0086] In other embodiments, the two transfer members 640 may also be respectively disposed on both sides of the first driving member 610 along the first direction, so that the lifting members 650 are respectively disposed on both sides of the transfer member 640 along the second direction.

[0087] It is understandable that the lifting mechanism 600 is also provided with sensing plates and sensors to detect the amount of movement of the transport mechanism in the vertical direction, thereby assisting in controlling the start and stop timing of the first driving member 610, and thereby being able to raise or lower the transport mechanism to a specific position.

[0088] The third aspect of the present application proposes a photovoltaic production line, which includes a process device and the transport device mentioned in the above embodiment, and the transport device can lift the transport mechanism to a height not lower than the supporting platform to transfer the material 800 to the supporting platform.

[0089] It can be understood that during the transfer process of the conveying device, the lifting mechanism 600 first lifts the conveying mechanism to a position above the loading platform, then the conveying mechanism transports the material 800 to the top of the loading platform, and then the lifting mechanism 600 descends to place the material 800 on the loading platform.

[0090] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
