[0027] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0028] The solar cell assembly laminating machine of the utility model comprises a frame library for storing frames. The frame library comprises a frame 8, a frame taking and placing mechanism 22 and a frame placing rack 20. The frame taking and placing mechanism is used to place the frame on the frame placing rack 20, or to take the frame from the frame placing rack, or to take the frame from the frame placing rack and place the frame on the frame placing rack. The frame placing rack is arranged on the main frame body 21 and supported by the main frame body. The top of the frame forms a plane for supporting the frame. The frame placing rack is used to support and store the frames stacked on each other.

[0029] like Figure 1-Figure 5 As shown, the basic structure of the frame 8 of the utility model is the same as the prior art, and its basic structure is a hollow frame. Since most solar cell modules are rectangular parts, the inner side of the frame is mostly rectangular, and the frame is also rectangular as a whole. The difference is that the frame body can be magnetically conductive as a whole or in part, so that the frame can be attracted with the magnetic attraction component of the magnetic attraction device. In order to make the frame body magnetic, the material for making the frame body can be made of magnetic conductive material. Preferably, a plurality of magnetic conductive components, such as a plate 5 of magnetic conductive material, are arranged at intervals on the frame body, so that the frame body is partially magnetic. Taking the frame as a rectangular frame as an example, a plate 5 with good magnetic conductivity is arranged on the upper surface of the frame body. The plate 5 can be an annular plate with the same shape as the frame body. When it is an annular plate, the four sides of the frame are all magnetic. It can also be a sheet. When it is a sheet, at least two oppositely arranged frames are equipped with plates. The plates are dispersedly arranged on the upper surface of the frame body, preferably evenly distributed on the upper surface of the frame body, and preferably, the plates are arranged on the two oppositely arranged long sides of the frame body. The pasting board is fixedly connected to the frame body by adhesive tape or glue, or by fasteners, or by riveting. The frames are stacked on the frame placement rack, and the frames are stacked opposite to each other, and the positions of the pasting boards are opposite to each other, which is convenient for taking and placing the frames.

[0030] In order to prevent the metal frame from scratching the transmission cloth and glass, and the glue overflowing from the components from adhering to the frame, it is best to configure a flexible protective layer outside the frame. The flexible protective layer is wrapped and covered on the surface of the frame. High-temperature cloth is usually used as the flexible protective layer. The flexible protective layer and the frame are usually connected by bonding or winding. At this time, the magnetic conductive component can be set on the outside of the flexible protective layer or on the inside of the flexible protective layer, and is directly fixed to the frame through a fixing piece or by bonding.

[0031] The frame pick-up and placement mechanism 22 of the utility model includes a magnetic device fixing frame 9, a magnetic device moving device (not shown in the figure), and a magnetic device 10. A plurality of magnetic devices are fixedly arranged below the magnetic device fixing frame 9. The magnetic device moving device can move the magnetic device fixing frame and the magnetic device located below the magnetic device fixing frame to a desired position. The magnetic device moving device is a prior art and will not be described in detail.

[0032] like Figure 3 and Figure 4 As shown, the magnetic device in the utility model is fixedly arranged on the edge of the magnetic device fixing frame 9 through a connecting seat 13. The magnetic device adopts a device or component that can be magnetized and demagnetized, for example, an electromagnet or a magnetic cylinder or a magnetic electric cylinder can be used. The magnetic device is fixedly connected to the magnetic device fixing frame through a connecting seat 13. The number of magnetic devices corresponds to the number and position of the magnetic components on the frame, so that the frame can be firmly attracted and moved. When the magnetic device is magnetized, it can have a magnetic attraction with the magnetic frame, so that it can be attracted together with the frame and move the frame under the drive of the magnetic device moving device. When it loses magnetism, the frame can be released so that the frame is placed in the target position. The magnetic cylinder is a prior art and can be purchased on the market. For example, the SGM-30 magnetic cylinder with the brand of KSOE. Kosol can be selected. In order to make the frame be attracted by the magnetic attraction device, the positional relationship between the magnetic attraction devices is consistent with the positional relationship between the frame or the magnetic conductive components on the frame. When the magnetic attraction device is located directly above the frame, the magnetic attraction device can face the magnetic conductive components, and when the magnetic attraction device falls, it attracts the frame.

[0033] When the laminating machine of the utility model stores frames in the frame warehouse, the magnetic suction device moving device drives the magnetic suction device with the frame attracted to move to a predetermined position above the frame placement rack, and drives the magnetic suction device to fall to the predetermined position and then loses magnetism, and the frame is placed on the frame placement rack, and this cycle is repeated to stack the frames one by one on the frame placement rack. When it is necessary to take the frame from the frame placement rack, the magnetic suction device moving device drives the frame taking and placing mechanism to move to the top of the frame and fall, and the magnetic suction device generates a suction force with the frame after being magnetized, so as to attract the frame, and the magnetic suction device moving device moves the frame to the target position.

[0034] When the magnetic device is connected to the magnetic device fixing frame, it is best to set an elastic buffer device 12. The elastic buffer device is set between the magnetic device and the connecting seat. When the magnetic device is attached to a magnetic conductive component such as a sticker, a contact buffer is provided to prevent the frame from being deformed and misaligned. In a better embodiment, the elastic buffer device is a spring 14 or an elastic block. When it is a spring, the spring is preferably sleeved outside the guide column 15. One end of the guide column is fixedly connected to the magnetic device, and the other end passes through the through hole set on the connecting seat and is limited by the axial limit device 16. The axial limit device is a limit nut, a limit plate, etc. set on the other side of the guide column. The spring is located between the connecting seat and the magnetic device. The guide column and the connecting seat are movably connected. In the utility model, the frames stored in the frame library are all frames whose frame bodies have magnetism.

[0035] In order to prevent or minimize displacement of the frame when removing the frame, when a frame made of magnetic conductive material is used, the magnetic component is magnetized only when it is attached to the frame. When a magnetic conductive component such as a sticker is set on the frame, the magnetic component of the magnetic device is attached to the sticker before it is magnetized. In order to prevent the frame from shifting when placing the frame, the magnetic component needs to be demagnetized and the frame released only after the frame completely falls onto the supporting surface.

[0036] It is best to set up a control device and a detection device for detecting the position of the magnetic suction component and the frame body. For example, a position detection device 1 is set to detect whether the magnetic suction component is in place with the frame. The position detection device 1 is electrically connected to the input end of the control device, and the magnetic suction device moving device and the magnetic suction device are both electrically connected to the output end of the control device. When taking the frame, the position detection device 1 detects whether the magnetic suction component of the magnetic suction device is in place with the magnetic conductive component. When it is detected that the magnetic suction components of all the magnetic suction devices are in place with the sticker, the control device controls the magnetic suction device to obtain magnetism so that the magnetic suction component is attracted to the sticker. When the frame is placed, the position detection device 1 detects that all the magnetic suction components are in place or the entire frame is in place. After the frame is in place, the control device controls the magnetic device to lose magnetism, so that the frame falls into place smoothly, which can prevent the frame from moving due to inconsistent magnetic attraction time or release time of the magnetic device, causing inaccurate position and deformation of the frame. This position detection device 1 can be a position sensor such as a proximity switch, and a position detection device 2 is set to detect the distance between the magnetic device and the board. The position detection device 2 is connected to the control device by electrical signals. When taking the frame, when the position detection device 2 detects that the distance between the magnetic device and the board reaches the set distance, the control device reduces the downward speed of the moving device of the magnetic device, so that the magnetic device slowly approaches the board to prevent the frame from being impacted and deformed. Similarly, when placing the frame, when the position detection device 2 detects that the distance between the magnetic device's magnetic component and the frame stored on the frame placement rack reaches the set distance, the control device reduces the downward speed of the moving device of the magnetic device, so that the magnetic device slowly approaches the frame and its board to prevent the frame from being impacted and deformed. The position detection device 2 can use a photoelectric sensor.

[0037] In the laminating machine of the utility model, the magnetic suction component of the magnetic suction device switches between two states of magnetization and demagnetization. When taking the frame, it is magnetized, and when placing the frame, it is demagnetized. Therefore, when taking the frame, the magnetic suction device only needs to attract the magnetic frame from the top of the frame to hold the frame. When taking the frame, it will not affect other frames, and will not collide with the frame below because the manipulator needs to be inserted under the frame when grabbing the frame. When taking the frame, it will not cause damage to the frame below, and will not cause the misalignment of the frame. The frames can be stacked together one by one from bottom to top for storage, and there is no need to set pads between the frames, thereby increasing the number of frames stored in the frame warehouse. When placing the frame, the moving device of the magnetic suction device drives the magnetic suction device to press the attracted frame onto the frame located at the top of the frame placement rack and then demagnetizes the magnetic suction device. In this way, the frame can lose the grip of the magnetic suction device after being fully supported. The stability of the frame placement is good, and the frame is not easy to be misaligned when placed.

[0038] Preferably, when taking the frame, the magnetic device moving device first drives the magnetic device fixing frame and the magnetic device to the top of the frame frame, and then descends, so that the magnetic device falls from the top of the board and contacts the frame, and the contact time of each magnetic component and each board is consistent, so that the position of the frame frame is protected when the magnetic component contacts the frame, which is conducive to keeping the position accuracy of the frame in the frame library, and preventing the frame in the frame library from shifting and affecting the removal of the next frame. With the device of the utility model, since the magnetic device and the magnetic conductive component of the frame are relative to each other, and the frame is grabbed by the surface-to-surface attraction, the frame will not be deformed when grabbing the frame. When placing the frame, the magnetic device moving device drives the magnetic device and the attracted frame to fall from the top of the frame on the placement rack. After the frame completely falls to the frame below or above the placement rack, the magnetic attraction is released to release the frame. The position of the frame can be consistent with the predetermined position during the process of taking and placing, and the stability of the frame position can be guaranteed.

[0039] In the laminating machine of the utility model, the frame warehouse can be set above or beside the frame return line to store the frames accumulated due to the change of production rhythm or to supplement the frames for the return line. It can also be placed outside the laminating machine to supply frames to the laminating machine or to take frames out of the laminating equipment for storage. The frame warehouses can be set at the same time in the above-mentioned positions, or only in one or several positions. In the laminating machine of the utility model, a magnetic suction device moving device can be set separately for the frame warehouse, or a frame picking and placing mechanism in the return line or a frame picking and placing mechanism of the feeding workbench or the discharging workbench can be used to realize the warehousing and storage of frames.
