[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight, generally composed of a photovoltaic panel and a frame. The frame of the photovoltaic panel has the advantages of protecting the photovoltaic panel, improving the power generation efficiency, and enhancing the structural stability. Therefore, each photovoltaic panel needs to be installed with a frame before leaving the factory. The existing frame installation generally uses a conveyor belt and a robotic arm to cooperate to achieve fully automatic frame installation for the photovoltaic panel. In order to adapt to the needs of installation and circularity, some existing photovoltaic panels are designed in shapes such as circular, elliptical, and triangular.

[0003] However, the existing automatic frame installation equipment can often only be applied to specific types of photovoltaic panels and frames such as rectangles and squares, and has limited adaptability to photovoltaic panels with different thicknesses, materials or designs, non-standard sizes or special-shaped photovoltaic panels, which limits the flexibility of the production line and the diversity of products.

[0004] Therefore, an automatic assembly device for photovoltaic panel frames is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an automatic assembly device for photovoltaic panel frames, so as to overcome the defect that the existing automatic installation equipment for photovoltaic panel frames cannot grasp and assemble special-shaped frames other than quadrilaterals. The specific technical solutions are as follows:

[0006] The automatic assembly device for photovoltaic panel frames includes a photovoltaic panel conveyor belt, an adaptive grasping device, a frame conveyor belt, and an automatic assembly device. The photovoltaic panel conveyor belt is located on one side of the frame conveyor belt, and the automatic assembly device is located below the photovoltaic panel conveyor belt for assembling the photovoltaic panel on the conveyor belt with the frame.

[0007] The adaptive grasping device is located between the photovoltaic panel conveyor belt and the frame conveyor belt. The adaptive grasping device includes a moving unit, a top plate, a support rod, a connecting rod, a telescopic claw, a first electric trolley, a second electric trolley, an electric push rod, a positioning rod, a screw drive assembly, and a motor. The top plate is connected to the moving unit, and the moving unit is used to move the top plate between the photovoltaic panel conveyor belt and the frame conveyor belt.

[0008] Three sliding grooves are provided on the top plate. The first electric trolley is symmetrically installed in the middle sliding groove, and the second electric trolley is symmetrically installed at both ends of the sliding grooves on both sides of the top plate. The lead screw drive assembly is installed on the side of the first electric trolley away from the top plate. One end of the connecting rod is connected to the lead screw drive assembly, and the telescopic gripper is installed at the other end of the connecting rod. The electric push rod is installed on the side of the first electric trolley away from the top plate, and the electric push rod is located on the side of the first electric trolley close to the center of the top plate. One end of the positioning rod is connected to the output end of the electric push rod, the motor is installed on the first electric trolley, and the output end of the motor is connected to the input end of the lead screw drive assembly;

[0009] One end of the support rod is installed on the side of the second electric trolley away from the top plate, and the telescopic gripper is rotatably installed on the other side of the support rod and can rotate and fit according to the shape of the frame. Each of the second electric trolley and the first electric trolley operates independently.

[0010] Preferably, a torsion spring is installed between the support rod and the telescopic gripper for resetting when the telescopic gripper releases the frame.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment, refer to Figures 1 to 3 .

[0024] The photovoltaic panel conveyor belt is located on one side of the frame conveyor belt. The photovoltaic panel conveyor belt and the frame conveyor belt sequentially transport the photovoltaic panels and frames to be assembled to a designated area for assembly. When the telescopic claw 4 touches the frame, the telescopic claw 4 will rotate and adjust to be located below the photovoltaic panel conveyor belt according to the shape of the frame, so as to assemble the photovoltaic panel on the conveyor belt with the frame.

[0025] The adaptive grasping device is located between the photovoltaic panel conveyor belt and the frame conveyor belt and is used to grasp the special-shaped frame onto the automatic assembly device. The adaptive grasping device can grasp both curved and flat shapes, so it can adapt to any shape such as circular, elliptical, and triangular, etc.

[0026] The adaptive grasping device includes a moving unit, a top plate 1, a support rod 2, a connecting rod 3, a telescopic claw 4, a first electric trolley 5, a second electric trolley 6, an electric push rod 7, a positioning rod 8, a lead screw transmission assembly, and a motor 9. The top plate 1 is connected to the moving unit, and the moving unit is used to move the top plate 1 between the photovoltaic panel conveyor belt and the frame conveyor belt.

[0027] There are three sliding grooves 10 or more than three sliding grooves 10 formed on the top plate 1. The number of the sliding grooves 10 is odd, so that the positioning rod 8 can be fixed at the middle part of the frame. The first electric trolley 5 is symmetrically installed in the middle sliding groove 10, and the second electric trolley 6 is symmetrically installed at both ends of the sliding grooves 10 on both sides of the top plate 1. The screw drive assembly is installed on the side of the first electric trolley 5 away from the top plate 1. One end of the connecting rod 3 is connected with the screw drive assembly. The motor 9 is installed on the first electric trolley 5, and the output end of the motor 9 is connected with the input end of the screw drive assembly. The connecting rod 3 is driven by the motor 9 to drive the screw assembly to move horizontally, so that the connecting rod 3 can move towards or away from the electric push rod 7, and clamp the frame fixed by the positioning rod 8. The first electric trolley 5 can adjust the positions of the electric push rod 7 and the positioning rod 8 according to the size and position of the frame.

[0028] The telescopic claw 4 is installed at the other end of the connecting rod 3. The opening size of the telescopic claw 4 is adjusted by a cylinder. When the first electric trolley 5 and the second electric trolley 6 move, the cylinder opens the opening of the telescopic claw 4 to the maximum. When it moves to the specified position, the cylinder contracts the opening of the telescopic claw 4 to be equal to the thickness of the frame, so as to grab the frame. The electric push rod 7 is installed on the side of the first electric trolley 5 away from the top plate 1 through bolts, and the electric push rod 7 is located on the side of the first electric trolley 5 close to the center of the top plate 1. One end of the positioning rod 8 is connected with the output end of the electric push rod 7. The positioning rod 8 is used to extend to the other side of the telescopic claw 4 relative to the frame and fit with the frame before the telescopic claw 4 grabs the frame, so as to avoid the telescopic claw 4 pushing the frame when grabbing the frame and causing the frame to shift.

[0029] One end of the support rod 2 is installed on the side of the second electric trolley 6 away from the top plate 1. The telescopic claw 4 is rotatably installed on the other side of the support rod 2 and can be rotated and fitted according to the shape of the frame. Each second electric trolley and the first electric trolley 5 operate independently according to the transmission signal of the single-chip microcomputer. Therefore, the present application can realize the grabbing of asymmetric frames.

[0030] A torsion spring is installed between the support rod 2 and the telescopic claw 4, which is used for resetting after the telescopic claw 4 releases the frame, so as to avoid the problem that the opening of the telescopic claw 4 does not face the frame when the telescopic claw 4 grabs the next frame, and ensure that the telescopic claw 4 can stably grab the frame.

[0031] A sensor 11 is installed on the telescopic gripper 4. The telescopic sensor 11 is electrically connected to the corresponding first electric trolley 5 and second electric trolley 6. When the sensor 11 detects the frame, the first electric trolley 5 and the second electric trolley 6 stop moving. By means of the sensor 11, the moving accuracy of the first electric trolley 5 and the second electric trolley 6 is further improved, avoiding the collision between the telescopic gripper 4 and the frame and causing damage to both. The sensor 11 here can be a proximity switch, an infrared sensor 11, a capacitance sensor 11, etc.

[0032] The positioning rod 8 is semi-cylindrical. A brushless motor 9 is installed between the electric push rod 7 and the first electric trolley 5. When the positioning rod 8 needs to fix the frame, it moves to the specified position driven by the first electric trolley 5, and the electric push rod 7 drives the positioning rod 8 to extend. At this time, the semi-cylinder does not contact the frame, and the arc surface faces away from the frame. After the electric push rod 7 stops starting, the brushless motor 9 drives the positioning rod 8 to rotate, so that the arc surface faces the frame and is tangent to and fits the frame. After the telescopic gripper 4 completes the grasping, the brushless motor 9 drives the positioning rod 8 to rotate, the arc surface faces away from the frame, and the electric push rod 7 drives the positioning rod 8 to contract, reducing the friction between the positioning rod 8 and the frame and avoiding damage to the face.

[0033] The positioning rod 8 is made of a polymer material, such as materials with a hardness lower than that of aluminum alloy, such as rubber and plastic. Since the frame of the photovoltaic panel is generally made of aluminum alloy, the positioning rod 8 can be prevented from damaging the frame.

[0034] In summary, the operation process of the automatic assembly equipment for the photovoltaic panel frame is as follows: the photovoltaic panel conveyor belt and the frame conveyor belt transport the photovoltaic panel and the frame to the specified area. The moving unit drives the top plate 1 to move directly above the frame, and the electric push rod 7 drives the positioning rod 8 to extend to fix the frame. The telescopic gripper 4 on the connecting rod 3 moves towards the frame and grabs the frame under the drive of the lead screw drive assembly. The telescopic gripper 4 on the support rod 2 moves towards the frame under the drive of the second electric trolley 6. When the telescopic gripper 4 touches the frame, the telescopic gripper 4 will rotate and adjust according to the shape of the frame, and finally realize the grasping of the frame. The moving unit drives the top plate 1 to move to the photovoltaic panel. When the telescopic gripper 4 touches the frame, the telescopic gripper 4 will rotate and adjust according to the shape of the frame and install the frame on the telescopic gripper 4 at the edge of the photovoltaic panel to complete the assembly of the photovoltaic panel and the frame. Then the photovoltaic panel conveyor belt and the frame conveyor belt transport the next group of photovoltaic panels and frames to the specified area, and so on in a cycle.
