The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0032] Please refer to Figures 1 to 4The application provides an auxiliary frame discharging device, which comprises a conveying member 10 and a support 20, the conveying member 10 is arranged on the support 20, the conveying member 10 has a supporting surface 101 for supporting an auxiliary frame, and the auxiliary frame discharging device further comprises a lifting assembly 30, the lifting assembly 30 comprises a lifting part 310 which can move up and down, the lifting part 310 has a lifting surface 301 for lifting the auxiliary frame, as shown by a dashed line in Figure 4 , the lifting assembly 30 further comprises a driving member 320 for driving the lifting part 310 to move between a first position and a second position, when the lifting part 310 is in the first position, as shown in Figure 4 , the lifting surface 301 is higher than the supporting surface 101; when the lifting part 310 is in the second position (not shown), the lifting surface 301 is lower than or flush with the supporting surface 101.

[0033] It can be understood that the auxiliary frame is generally a rectangular frame, and the auxiliary frame is used to assist the process of aligning the edges of a front glass and a back glass, and the auxiliary frame needs to be removed after the front glass and the back glass are laminated into a laminated piece. The auxiliary frame discharging device in the embodiment is used to assist the auxiliary frame, and the use mode is as follows: the auxiliary frame and the laminated piece are in the direction of the orthographic projection of the supporting surface 101 of the conveying member 10, the laminated piece with the auxiliary frame moves to the upper side of the auxiliary frame discharging device on the conveying member 10, and the opposite two side lengths of the auxiliary frame are just above the lifting part 310 of the lifting assembly 30, at this time, the lifting part 310 is driven by the driving member 320 to move from the second position to the first position, and the auxiliary frame is lifted from the supporting surface 101 to the first position, the lifting part 310 does not contact the laminated piece, so that the laminated piece is still on the supporting surface 101. Then the auxiliary frame at the first position is removed by using manual or automatic mode, so that the removal work of the auxiliary frame is completed.

[0034] It can be understood that, in the process of removing the auxiliary frame from the first position, due to the supporting effect of the lifting part 310 on the auxiliary frame, the auxiliary frame can be prevented from falling down during the process of removal and transportation, so that the auxiliary frame is prevented from mistakenly hurting the laminated piece, and the product qualified rate of the laminated piece is improved.

[0035] Further, the rotating member 311 can be a universal wheel with multiple rotating directions, so that the auxiliary frame can be removed from the first position from any direction. The rotating member 311 can also have only one rotating direction, as long as the auxiliary frame can be removed from the rotating member 311, and the application does not limit this. Further, when the rotating member 311 has only one rotating direction and the second position is the position where the lifting surface 301 is flush with the supporting surface 101, the direction of removing the auxiliary frame from the rotating member 311 is the same as the direction of transporting the auxiliary frame by the conveying member 10, so that the auxiliary frame can move with the conveying member 10.

[0036] Illustratively, the driving member 320 can use a cylinder, a hydraulic cylinder, an electric push rod, an electric screw rod, a screw lift, a scissor lift, a magnetostrictive actuator, a worm gear, a gear rack, etc. with a lifting function, and the present application does not limit this. It can be understood that the driving member 320 has an extendable driving shaft 321, and the driving shaft 321 is connected with the lifting part 310. Similarly, the conveying member 10 can be a belt, and can also be a chain, a roller, etc. capable of conveying the laminated piece with the auxiliary frame, and the present application does not limit this.

[0037] In one embodiment, the lifting part 310 is provided with a plurality of rotating members 311, and the rotating members 311 are used in sliding cooperation with the auxiliary frame, so that the auxiliary frame can be moved away from one side of the rotating members 311. The surface in contact between the rotating members 311 and the auxiliary frame constitutes the lifting surface 301. In this way, the friction between the auxiliary frame and the rotating members 311 can be reduced, the auxiliary frame can be conveniently moved away from the rotating members 311, and the burden of manually removing the auxiliary frame can be reduced.

[0038] It can be understood that the auxiliary frame has a long side and a short side, and the auxiliary frame can be moved along the long side or the short side, and the present application does not limit this.

[0039] In one embodiment, referring to Figure 2 , the lifting part 310 further includes a first rod 313, the extension direction of the first rod 313 intersects with the direction in which the conveying member 10 conveys the auxiliary frame, and the driving member 320 drives the first rod 313 to move between a first position and a second position; the rotating member 311 is arranged on the first rod 313, and the movement direction of the auxiliary frame on the rotating member 311 is the same as the extension direction of the first rod 313.

[0040] It can be understood that the laminated piece and the photovoltaic module are generally produced using a production line, that is, the upstream and / or downstream of the conveying member 10 is further connected with other structures. In the present embodiment, the movement direction of the auxiliary frame on the rotating member 311 intersects with the direction in which the conveying member 10 conveys the auxiliary frame, that is, the auxiliary frame is not moved away from the direction in which the auxiliary frame is conveyed by the conveying member 10. When the auxiliary frame unloading device in the present embodiment is installed to the original production line, the auxiliary frame unloading device will not affect the work of the production line, and the universality of the auxiliary frame unloading device is improved.

[0041] Further, the extension direction of the first rods 313 is perpendicular to the direction in which the conveying member 10 conveys the auxiliary frame, and the number of the first rods 313 is two, and the two first rods 313 are arranged on the outer sides of the support 20 and are oppositely arranged, and the rotating members 311 are correspondingly arranged on the two first rods 313, and the distance between the two oppositely arranged rotating members 311 is equal to the length of the short side of the auxiliary frame, so that the auxiliary frame can be moved away along the long side direction of the auxiliary frame. It can be understood that when the front glass and the back glass are laminated, the auxiliary frame is arranged on the bottom surface and the side surface of the laminated member. Before the laminated member with the auxiliary frame is placed on the conveying member 10, the laminated member with the auxiliary frame needs to be turned over to turn the auxiliary frame to the top of the laminated member, so that the auxiliary frame and the laminated member can be separated in a manner of lifting only the auxiliary frame without lifting the laminated member. In the embodiment, the rotating member 311 is arranged on the first rod 313, and the auxiliary frame can be moved away along the long side direction of the auxiliary frame, which can be adapted to the pipeline for turning over along the long side of the auxiliary frame, so that the difficulty of turning over the laminated member with the auxiliary frame is reduced, and the probability of accidents in the turning over process is also reduced, thereby improving the product qualification rate of the laminated member.

[0042] In one embodiment, the lifting part 310 further comprises a plurality of connecting rods 312 extending in the up-down direction, and the connecting rods 312 are correspondingly arranged with the rotating members 311, the rotating members 311 are rotatably arranged on the upper ends of the connecting rods 312, and the lower ends of the connecting rods 312 are fixedly connected to the first rods 313. It can be understood that the conveying member 10 has a certain height in the direction of gravity, and the conveying member 10 has a bottom surface opposite to the supporting surface 101, and the bottom surface moves synchronously with the supporting surface 101. The connecting rod 312 increases the distance between the rotating member 311 and the first rod 313, so that the first rod 313 can be arranged away from the bottom surface of the conveying member 10, so that the activity range of the first rod 313 can be increased, and the movement of the conveying member 10 can be avoided, thereby reducing the running accidents of the auxiliary frame discharging device.

[0043] In one embodiment, the rotating member 311 is a roller, and the rotating member 311 is arranged on the upper end of the connecting rod 312 through a bearing. In this way, not only can the friction between the auxiliary frame and the rotating member 311 be reduced, and the auxiliary frame can be conveniently moved away from the rotating member 311, thereby reducing the burden of manual removal of the auxiliary frame, but also the roller is convenient and easy to obtain, thereby saving production costs.

[0044] In one embodiment, the conveying member 10 further has a vertical surface 102 extending in the direction in which the conveying member 10 conveys the auxiliary frame, and the vertical surface 102 is provided with the rotating members 311 on both sides. In this way, the distance between the adjacent rotating members 311 can be reduced, and the auxiliary frame can be prevented from falling off the rotating member 311 when moving on the rotating member 311, and the auxiliary frame can be prevented from accidentally injuring the laminated member, thereby improving the product qualification rate of the laminated member.

[0045] Illustratively, the conveying members 10 are belts, and the number of the belts is four. Each of the belts is provided with a plurality of rotating members 311 on both sides. In this way, the distance between adjacent rotating members 311 can be further reduced by increasing the number of the rotating members 311, so as to avoid the auxiliary frame from falling off the rotating members 311 when the auxiliary frame moves on the rotating members 311. In other embodiments, the belts can also be of other numbers, which are not limited in the present application.

[0046] In one embodiment, the lifting assembly 30 further comprises a fixing part 330 mounted on the support 20, and the driving member 320 is fixed to the fixing part 330. The driving shaft 321 of the driving member 320 is connected with the first rod 313. In this way, the space occupied by the support 20 can be reused to reduce the volume of the auxiliary frame blanking device.

[0047] Further, the lifting part 310 of the lifting assembly 30 further comprises a second rod 314, and both ends of the second rod 314 are fixedly connected with the two first rods 313. The fixing part 330 comprises a third rod 331 and a fourth rod 332. The extending direction of the third rod 331 is the same as that of the second rod 314, and the extending direction of the fourth rod 332 is the same as that of the first rod 313. The third rod 331 and the fourth rod 332 are fixedly connected, and the fourth rod 332 is mounted on the support 20. One end of the driving member 320 without the driving shaft 321 is fixed to the third rod 331, and the driving shaft 321 of the driving member 320 is connected with the first rod 313 through the second rod 314.

[0048] Illustratively, the number of the second rods 314 is two. In this way, the pressure of the first rod 313 on the end of each second rod 314 can be reduced, and the lifting part 310 is more stable. The number of the second rods 314 can also be other numbers, which are not limited in the present application. Further, the number of the driving members 320 is also two, and each driving member 320 is connected with one second rod 314. In this way, the output of each driving member 320 can be reduced, and the service life of the driving member 320 is prolonged. The number of the driving members 320 can also be other numbers, which are not limited in the present application. The number of the third rods 331 and / or the fourth rods 332 is two. In this way, not only the structure of the fixing part 330 can be stabilized, but also the fixing part 330 can be avoided from being too bulky to reduce the burden on the assembly line. The number of the third rods 331 and / or the fourth rods 332 can also be other numbers, which are not limited in the present application.

[0049] In one embodiment, with reference to Figure 1The support 20 comprises a cross beam 210 and a longitudinal beam 220, the cross beam 210 and the longitudinal beam 220 are fixedly connected, and the cross beam 210 and the longitudinal beam 220 surround an internal space 201, and the driving member 320 is located in the internal space 201. In this way, not only the driving member 320 can be avoided from being damaged, but also the internal space 201 occupied by the support 20 can be reused.

[0052] In one embodiment, the number of the first rods 313 is two, and the two first rods 313 are arranged on the outer sides of the internal space 201 and are arranged oppositely.
