Description

Technical Field

[0001] The utility model relates to the field of solar cells, and relates to a lifting device for a cavity upper cover of a side wall passivation coating device and a coating device. Background Art

[0002] Solar cells are semiconductor devices that convert sunlight directly into electrical energy. They are environmentally friendly, green and renewable, so in today's energy shortage situation, solar cells have broad development prospects. In the production process of solar cells, coating plays a vital role in improving the conversion efficiency of cells. The most common method is to use circular cavity coating equipment to coat solar cells.

[0003] In the prior art, all circular cavity coating equipment is designed with a flip cover. The upper cover of the cavity needs to be flipped 90 degrees. Because the flip cover is lifted by a lever, it requires a high lifting force and requires the purchase of very expensive equipment. After flipping, the angle of the top cover is almost perpendicular to the ground, occupying the upper space.

[0004] It can be seen that overcoming the deficiencies of the prior art, providing an improved cavity cover, reducing the requirements for lifting force, and ultimately achieving cost reduction and efficiency improvement have become technical challenges that need to be urgently solved by those skilled in the art.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the following embodiments are only some specific implementation methods of the utility model, but not all embodiments. The following exemplary embodiment description is only illustrative and does not limit the utility model and its application or use. Based on the description of the utility model, all other technical solutions obtained by ordinary technicians in this field without creative labor are within the scope of protection of the utility model.

[0027] For ease of description, the present invention uses spatially relative terms, such as "above", "above", "on the upper surface of", "above", etc., to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figures. It should be understood that the spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above" or "above" will be positioned as "below" or "below". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0028] like Figure 1 As shown, the first aspect of the utility model is a jacking device, comprising: a reducer, a servo motor, a power conversion mechanism 2, a guide rod 3, a linear bearing, and an assembly mechanism 4.

[0029] The reducer and the servo motor constitute the power mechanism 1, but are not limited thereto. The power mechanism 1 may also include other suitable power supply devices as required. The power mechanism 1 is used to provide power for the jacking device. The servo motor is the source of power output. After calculation, a suitable reduction ratio is selected to increase the output torque to meet the power requirements for jacking.

[0030] The power conversion mechanism 2 is arranged above the power mechanism 1, and preferably includes an electric cylinder, but it is not limited thereto. The power conversion mechanism 2 may also include other suitable devices for converting power as needed. The power conversion mechanism 2 is a bearing mechanism for power output, which converts the power output of the power mechanism 1 into lifting power. The electric cylinder uses various motors to drive various screws to rotate, which are converted into linear motion through nuts, and push the slide to perform reciprocating linear motion along various guide rails like a cylinder. The electric cylinder is preferably a T-type screw rod, which is small in size, very flexible in design, very low in noise, and has good corrosion resistance. It can be used to meet the requirements of vertical applications and self-locking functions.

[0031] The guide rod 3 and the linear bearing constitute a moving mechanism, which is arranged on both sides of the power mechanism 1 and is used to move in the vertical direction for lifting. The linear bearing can withstand a large load and plays a guiding role during lifting to prevent overall deviation. The guide rod 3 is connected to the assembly mechanism 4 via the linear bearing.

[0032] The assembly mechanism 4 is connected to the power conversion mechanism 2 and the moving mechanism, and is used to assemble the lifting device with the cavity cover, and preferably includes a floating joint. Due to errors in processing and assembly, the equipment cannot achieve the ideal accuracy and requirements when lifting. Therefore, a floating joint is used within the range of ensuring accuracy to ensure that the floating range during lifting covers the error of the equipment and ensure smooth operation.

[0033] The second aspect of the utility model is a side wall passivation coating device, which includes the lifting device involved in the first aspect of the utility model. The lifting device is arranged on both sides of the cavity, the weight to be lifted is calculated to make the required power and speed requirements, and the motor is rotated according to the calculation result, and the upper cover is lifted from both sides through lifting.

[0034] The jacking device of the utility model is used to carry out the coating process of the coating equipment, which solves the problem of equipment requiring large output force, and solves the problem of flipping and occupying the top space without using a flip cover. It is connected to the cavity plate during installation, avoiding the adverse consequences of being connected to the ground and being very inconvenient to adjust. It is easy to install, reduces costs and improves production efficiency.

[0035] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
