[0028] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0029] In the present invention, for the sake of simplicity, the feeding device or the discharging device is abbreviated as the feeding device / discharging device, and the feeding transmission platform or the discharging transmission platform is abbreviated as the feeding transmission platform / discharging transmission platform. Figure 1As shown, the automatic lifting type photovoltaic module laminator of the structure of the utility model is a laminator, including a laminator mainframe, a laminator lifting mechanism, and at least a feeding device or a discharging device. The laminator mainframe includes an upper box and a working platform, and a rubber sheet is arranged on the upper box as a laminating component. The rubber sheet is fixed at the opening of the upper box body by a rubber sheet fixing device, and the opening of the upper box body is sealed by the rubber sheet. When laminating, the upper box and the working platform are closed, and the rubber sheet separates the two into an upper vacuum chamber and a lower vacuum chamber. The feeding device includes a feeding transmission platform, which is docked with the working platform of the laminator mainframe B to transmit the components to be laminated to the working platform of the laminator mainframe, and the discharging device includes a discharging transmission platform, which is docked with the working platform of the laminator mainframe to receive and transmit the laminated components. When the laminator is multi-layer, it includes a laminator mainframe arranged up and down in multiple layers and a feeding transmission platform or a discharging transmission platform arranged up and down in multiple layers, and the working platform of each layer is docked with the feeding transmission platform or the discharging transmission platform of the corresponding layer. The rubber sheet lifting mechanism B3 is arranged on the top of the frame of the main body B of the laminator, near one end of the feeding device / discharging device A. The rubber sheet lifting mechanism lifts the rubber sheet from one side of the feeding device / discharging device to the feeding transfer platform / discharging transfer platform of the feeding device / discharging device A, and the rubber sheet lifting can be completed. If the laminator has multiple layers, it can be lifted to the feeding transfer platform / discharging transfer platform of the feeding device / discharging device of the corresponding layer. For example, when it is two layers, it is transferred from the first layer position 1 of the feeding device / discharging device A to the first layer working platform B1 or from the second layer position A2 to the second layer working platform B2.

[0030] like Figure 3As shown, the rubber sheet lifting mechanism of the utility model structure includes a swing arm 5 and a swing arm bracket. The swing arm bracket includes a fixed column 1, an upper connecting plate 3 and a lower connecting plate 2. The fixed column is vertically arranged, and its upper and lower ends are respectively fixedly connected to the upper connecting plate and the lower connecting plate to form a stable bracket. The lower connecting plate is fixedly connected to the top of the frame. The swing arm 5 includes a swing arm column 501 and a swing arm crossbeam 502.

The swing arm crossbeam 502 is located above the feeding device / discharging device, and the projection of the cantilever end of the swing arm crossbeam falls on the feeding transmission platform / discharging transmission platform. Preferably, an inclined swing arm reinforcement rod 503 is provided, the lower end of which is fixedly connected to the swing arm column, and the upper end of which is fixedly connected to the cantilever end of the swing arm beam. It supports and strengthens the swing arm beam. It also includes a lifting device, which includes a flexible lifting rope, a pulling device and a reversing device. One end of the flexible lifting rope is provided with a lifting device, such as a hook 10 or a snap hook, and the other end is used to connect with the pulling device. The reversing device is located at the cantilever end of the swing arm beam. The end of the flexible lifting rope provided with the lifting device is reversed by the reversing device and then droops, and the other end is pulled vertically or horizontally by the pulling device. The reversing device can be a simple pulley or a steering wheel. Better yet, the structure of the utility model is adopted. Figure 5 As shown, the structure of the preferred reversing device 8 includes a base 801, a limiting shaft 802, a reversing roller 803, and a reversing shaft 804. The base includes left and right side vertical plates 808 and a horizontal plate connecting the left and right vertical plates. The limiting shaft 802 is rotatably fixed between the left and right vertical plates of the base 801. The reversing shaft 804 is fixedly arranged between the left and right vertical plates of the base 801 and is located below or obliquely below the limiting shaft, and is at a certain distance from the limiting shaft for the flexible lifting rope to pass through. The reversing roller 803 is rotatably arranged on the reversing shaft 804 through a bearing 807, so that the reversing roller 803 can rotate freely. Positioning sleeves 805 are arranged on both sides of the reversing roller 803 for axial positioning of the reversing roller 803. Flexible lifting ropes such as steel wire ropes 9 pass between the limiting shaft 802 and the reversing roller 803. When being pulled, the flexible lifting rope is limited by the left and right vertical plates, the limiting shaft and the reversing roller, so that its position does not deviate. Except steel wire rope, cable, chain etc. can be used as flexible lifting rope. Preferably, both ends of reversing roller 803 are provided with baffle plate 809, and baffle plate 809, reversing roller 803 and limiting shaft 802 form limiting space.

[0031] Preferably, the swing arm column is rotatably connected to the upper connecting plate and the lower connecting plate through a rotating device 4. Figure 4As shown, the rotating device 4 includes a vertical shaft 401, a bearing with a seat 402, a bearing sleeve 403, a thrust bearing 404, and a dust cover 405. The vertical shaft 401 is fixedly arranged with the swing arm column 501, that is, fixed as one with the swing arm, and both ends of the vertical shaft 401 are rotatably connected with the upper connecting plate and the lower connecting plate through the bearing with a seat 402. A thrust bearing 404 is also arranged at the lower end of the vertical shaft 401 to increase the vertical upward thrust. The thrust bearing 404 is arranged in the bearing sleeve 403, and the bearing sleeve 403 is fixedly arranged on the lower connecting plate 2. A dust cover 405 is also arranged on the upper part of the thrust bearing 404. The thrust bearing is clamped above the lower connecting plate 2 and below the dust cover to prevent dust from entering. The bearing with a seat is located below the lower connecting plate.

[0032] As shown in the figure, the pulling device can be a manual pulling device or an electric pulling device. For example, the following structure can be used. Figure 3 As shown, a motor and a winch unit 6 equipped with a limiting unit 7 can be used as a pulling device to pull the flexible lifting rope. The winch unit 6, the limiting unit 7 and the motor are all fixedly arranged on the swing arm cross beam 502 at one end close to the vertical axis 401. The winch unit 6 is a finished product that can be purchased on the market. The wire rope is used as a flexible lifting rope. One end of the wire rope is wound around the winch of the winch unit, and the other end is bypassed by the reversing device and fixed with a lifting device. The motor drives the winch to rotate, thereby retracting and releasing the wire rope 9 wound around the winch, and the limiting unit 7 is used to ensure that the position of the wire rope 9 is within the normal working range. The wire rope 9 is vertically positioned through the reversing device 8, and the lifting device arranged at the end can use a hook 10, preferably a rotating hook. The rotation has quick release and self-locking functions, and can also rotate freely, so it is convenient to adjust the direction after lifting the rubber sheet C. Combined with Figure 2 As shown, when in use, the swing beam 502 is swung in the horizontal plane so that its cantilever end extends to the outside of the feeding and conveying platform / discharging platform of the feeding device / discharging device, and the rolled rubber sheet C is hung on the lifting device of the rubber sheet lifting mechanism B3, and the wire rope is reeled in to lift the rubber sheet so that it is higher than the feeding and conveying platform / discharging conveying platform of the layer height of the installed rubber sheet, and then it is swung back to lift the rubber sheet to the first layer A1 or the second layer A2 of the feeding device / discharging device A, and then the direction of the lifting device is manually adjusted to put the rolled rubber sheet C into the appropriate position of the feeding device / discharging device A, and then the lifting device of the rubber sheet lifting mechanism B3 is released to lay the rolled rubber sheet C flat on the first layer A1 or the second layer A2 of the feeding device A, and finally the rubber sheet is conveyed to the working platform of the laminating machine host B through the feeding and conveying platform / discharging conveying platform and the photovoltaic module conveying device, and if it is a multi-layer laminating machine, it is conveyed to the working platform of the corresponding layer.

[0033] Of course, the winch device can also be arranged on the ground or other equipment. As long as the swing arm cross beam can swing, and the reversing point of the flexible lifting rope is located at the cantilever end of the swing arm cross beam, it is possible to lift the rubber sheet onto the feeding transmission platform / discharging transmission platform.

[0034] like Figure 6 As shown, a fixed pulley block can also be used instead of the winch unit 6 as the pulling device, the fixed pulley 1 is arranged at one end of the swing arm beam close to the feeding device / discharging device, the fixed pulley 2 is located below the fixed pulley 1, and the end of the flexible lifting rope opposite to the end connected to the lifting device is fixed. Figure 7 As shown, a movable pulley block can also be used as a pulling device. At this moment, the changing and drawing device adopts a fixed pulley, which is arranged below the cantilever end of the swing arm cross beam, and the movable pulley block is connected with the fixed pulley.

[0035] like Figure 8 and Fig. 9 As shown, a hand chain hoist or electric hoist can also be used as the pulling device, and the hand chain hoist or electric hoist is arranged at the end of the cantilever end of the swing arm cross beam. In this case, since the lifting point of the pulling device is at the same position as the pulling device, both are located at the end of the cantilever end of the swing arm cross beam, there is no need to set a separate reversing device.

[0036] The rubber sheet lifting mechanism provided by the utility model can very conveniently lift and transport the rubber sheet, greatly saving manpower and ensuring personal safety. The structure is simple and the reliability is high.
