[0033] Figure 1 , is a schematic diagram of the structure of a photovoltaic screen limiting device in an embodiment.

[0034] In this embodiment, if Figure 1 As shown, the photovoltaic screen limiting device includes a bearing mechanism 10 , an adsorption mechanism 20 and a clamping mechanism 30 .

[0035] The adsorption mechanism 20 is disposed on the carrying mechanism 10 and can adsorb the film surface of the photovoltaic screen.

[0036] The carrying mechanism 10 may be a functional structure arranged below the adsorption mechanism 20 and the clamping mechanism 30 in the vertical direction, and capable of carrying the adsorption mechanism 20 and the clamping mechanism 30. The adsorption mechanism 20 may be a functional structure arranged above the carrying mechanism 10 in the vertical direction, and capable of adsorbing the film surface of the photovoltaic screen under the action of vacuum adsorption to positionally constrain the end surface of the photovoltaic screen near the middle area, and capable of sensing the vacuum adsorption action. Optionally, the carrying mechanism 10 may be a jig bottom plate. The adsorption mechanism 20 may be a vacuum adsorption jig.

[0037] The adsorption mechanism 20 includes an adsorption component 220 and an adsorption sensing component 240. The adsorption sensing component 240 is connected to the adsorption component 220, and the adsorption sensing component 240 can sense the pressure value of the adsorption component 220; the adsorption component 220 is arranged on the surface of the supporting mechanism 10 close to the photovoltaic screen, and can adsorb the film surface of the photovoltaic screen; the adsorption sensing component 240 is arranged on the side of the supporting mechanism 10 away from the photovoltaic screen.

[0038] The adsorption component 220 may be a functional component that is vertically disposed above the carrier mechanism 10 and directly opposite to the lower surface of the photovoltaic screen, and is capable of adsorbing the film surface of the photovoltaic screen under vacuum adsorption. The adsorption sensing component 240 may be a functional component that is vertically disposed below the carrier mechanism 10 and connected to the adsorption component 220, and is capable of sensing the vacuum adsorption effect between the adsorption component 220 and the film surface of the photovoltaic screen. Optionally, the adsorption component 220 may be a fixture body. The adsorption sensing component 240 may be a vacuum pressure switch.

[0039] Through the coordinated working relationship between the adsorption component 220 and the adsorption sensing component 240 in the adsorption mechanism 20, it is possible to realize the position constraint of the end face of the photovoltaic screen near the middle area while detecting the vacuum adsorption effect between the adsorption component 220 and the membrane surface of the photovoltaic screen in real time, thereby improving the damage to the photovoltaic screen caused by excessive vacuum adsorption, and further improving the limiting and fixing effect of the adsorption mechanism 20 on the photovoltaic screen.

[0040] The clamping mechanism 30 is arranged outside the adsorption mechanism 20, and includes a clamping limit assembly 320 and a clamping drive assembly 340. The clamping drive assembly 340 can drive the side of the photovoltaic screen to abut against the clamping limit assembly 320. The clamping limit assembly 320 and the clamping drive assembly 340 are relatively arranged outside the adsorption mechanism 20. The clamping drive assembly 340 can abut against the first side of the photovoltaic screen and drive the second side of the photovoltaic screen to abut against the clamping limit assembly 320. The first side and the second side are opposite sides of the photovoltaic screen.

[0041] The clamping mechanism 30 may be a functional structure that is arranged above the carrier mechanism 10 and outside the adsorption mechanism 20 in the vertical direction, and can drive the side of the photovoltaic screen to abut against the clamping limit assembly 320 to constrain the position of the photovoltaic screen away from the side of the adsorption mechanism 20. The clamping limit assembly 320 may be a functional component that is arranged above the carrier mechanism 10 in the vertical direction, arranged on the outside of the adsorption mechanism 20 opposite to the clamping drive assembly 340, and can abut against the side of the photovoltaic screen away from the adsorption assembly 220 to constrain the position of the photovoltaic screen. The clamping drive assembly 340 may be a functional component that is arranged above the carrier mechanism 10 in the vertical direction, arranged on the outside of the adsorption mechanism 20 opposite to the clamping limit assembly 320, and can abut against the side of the photovoltaic screen away from the adsorption assembly 220 to drive the photovoltaic screen to move toward the clamping limit assembly 320.

[0042] The clamping drive assembly 340 includes a first clamping drive assembly and a second clamping drive assembly, and the driving direction of the first clamping drive assembly is perpendicular to the driving direction of the second clamping drive assembly. The clamping limit assembly 320 includes a first clamping limit assembly and a second clamping limit assembly, and the first clamping limit assembly and the first clamping drive assembly are arranged opposite to each other, and the second clamping limit assembly and the second clamping drive assembly are arranged opposite to each other.

[0043] The first clamping drive assembly and the second clamping drive assembly can both be drive cylinders. The first clamping limit assembly and the second clamping limit assembly can both be positioning stop pins. During the photovoltaic screen positioning process, the drive cylinder abuts against one side of the photovoltaic screen and drives the photovoltaic screen to move toward the positioning stop pin arranged opposite to the current cylinder until the other side of the photovoltaic screen abuts against the positioning stop pin, thereby clamping and fixing the side of the photovoltaic screen.

[0044] Through the coordinated action relationship among the clamping drive component 340, the clamping limit component 320 and the adsorption mechanism 20 in the clamping mechanism 30, it is possible to realize position constraint on the end face of the photovoltaic screen close to the middle area while realizing position constraint on the side of the photovoltaic screen away from the adsorption mechanism 20. That is, adding the abutting and clamping effect of the clamping mechanism 30 in the area where the vacuum adsorption effect of the adsorption mechanism 20 is relatively weak can enhance the position constraint effect on the photovoltaic screen with a larger size, thereby improving the limiting and fixing effect of the photovoltaic screen.

[0045] It should be noted that, for photovoltaic screens with smaller sizes, the adsorption component 220 in the adsorption mechanism 20 only performs vacuum adsorption on the corners and end faces of the photovoltaic screen, and cooperates with the clamping drive component 340 and the clamping limit component 320 in the clamping mechanism 30 to positionally constrain the sides of the photovoltaic screen, which can also improve the limiting and fixing effect of the photovoltaic screens with smaller sizes. In addition, depending on the size and clamping requirements of the photovoltaic screen, the clamping drive component 340 and the clamping limit component 320 in the clamping mechanism 30 can positionally constrain the two sides of the photovoltaic screen, or they can positionally constrain the four sides of the photovoltaic screen, thereby meeting the different limiting and fixing requirements of photovoltaic screens of different sizes, further improving the feasibility of the photovoltaic screen limiting device, and expanding the scope of practical application.

[0046] Figure 2 , is a schematic diagram of the structure of a photovoltaic screen limiting device in an embodiment.

[0047] In this embodiment, if Figure 2 As shown, the photovoltaic screen limiting device also includes a visual positioning mechanism 40 and a lifting mechanism 50.

[0048] The visual positioning mechanism 40 includes a backlight source 420 and a visual camera 440 (not shown). The backlight source 420 is disposed on a side of the supporting mechanism 10 away from the photovoltaic screen, and the visual camera 440 is disposed above the supporting mechanism 10 in a vertical direction.

[0049] The visual positioning mechanism 40 may be a functional structure that is vertically disposed above and below the supporting mechanism 10 and is capable of optically analyzing the position of the photovoltaic screen.

[0050] The lifting mechanism 50 is arranged on the side of the carrying mechanism 10 away from the photovoltaic screen, and can drive the carrying mechanism 10, the adsorption mechanism 20 and the clamping mechanism 30 to rise and fall to a preset height. The lifting mechanism 50 includes a lifting drive assembly 520 and a slide rail assembly 540, and the lifting drive assembly 520 can drive the carrying mechanism 10, the adsorption mechanism 20 and the clamping mechanism 30 to move along the extension direction of the slide rail assembly 540.

[0051] The lifting mechanism 50 may be a functional structure that is arranged below the supporting mechanism 10 in the vertical direction and can drive the supporting mechanism 10, the adsorption mechanism 20 and the clamping mechanism 30 to move in the vertical direction. The lifting drive assembly 520 may be a functional assembly that is arranged below the supporting mechanism 10 in the vertical direction, is slidably connected to the slide rail assembly 540, and can drive the supporting mechanism 10, the adsorption mechanism 20 and the clamping mechanism 30 to move along the extension direction of the slide rail assembly 540. The slide rail assembly 540 may be a functional assembly that is slidably connected to the lifting drive assembly 520 and can constrain the movement direction of the lifting drive assembly 520. Optionally, the lifting mechanism 50 may be a height lifting module. The lifting drive assembly 520 may be a table-type lifting body. The slide rail assembly 540 may be a guide rail slider.

[0052] Through the backlight source 420 and the visual camera 440 in the visual positioning mechanism 40, the horizontal position information of the photovoltaic screen can be collected and analyzed, and the film surface of the photovoltaic screen can be observed, so as to limit and detect the horizontal position of the photovoltaic screen; through the lifting drive assembly 520 and the slide rail assembly 540 in the jacking mechanism 50, the vertical position of the photovoltaic screen can be adjusted, which is convenient for the subsequent marking and cutting of the photovoltaic screen, thereby improving the feasibility and scope of application of the photovoltaic screen limiting device.

[0053] During the photovoltaic screen scribing and cutting process, the photovoltaic screen is placed on the upper surface of the carrier mechanism 10 (such as the fixture bottom plate), the adsorption component 220 (such as the fixture body) in the adsorption mechanism 20 adsorbs the film surface of the photovoltaic screen, and the adsorption sensing component 240 (such as a vacuum pressure switch) in the adsorption mechanism 20 displays the pressure value between the adsorption component 220 (such as the fixture body) and the film surface of the photovoltaic screen and can output an abnormal warning signal; the clamping drive component 340 (such as a driving cylinder) in the clamping mechanism 30 presses and drives the side screen of the photovoltaic screen to move. The frame moves toward the clamping limit assembly 320 (such as a positioning stop pin) until the side frame of the photovoltaic screen abuts against the clamping limit assembly 320 (such as a positioning stop pin); in addition, the backlight source 420 in the visual positioning mechanism 40 cooperates with the visual camera 440 for positioning, and the lifting drive assembly 520 (such as a desktop lifting body) in the lifting mechanism 50 drives the supporting mechanism 10, the adsorption mechanism 20 and the clamping mechanism 30 to rise and fall along the extension direction of the slide rail assembly 540 (such as a guide rail slider) until the preset height is reached for subsequent photovoltaic screen scribing and cutting.

[0054] In the process of photovoltaic screen scribing and cutting, Figure 3 to Figure 4 As shown, the adsorption mechanism 20 arranged on the supporting mechanism 10 can adsorb the film surface of the photovoltaic screen under the action of vacuum adsorption, so as to realize the position constraint of the end face of the photovoltaic screen close to the middle area. At the same time, the clamping mechanism 30 arranged on the outside of the adsorption mechanism 20 includes a clamping limit component 320 and a clamping drive component 340. The clamping drive component 340 can drive the side of the photovoltaic screen to abut against the clamping limit component 320, so as to realize the position constraint of the side of the photovoltaic screen away from the adsorption mechanism 20, that is, the abutting and clamping effect of the clamping mechanism 30 is added in the area where the vacuum adsorption effect of the adsorption mechanism 20 is relatively weak, so as to enhance the position constraint effect on the photovoltaic screen with larger size, thereby improving the problem of relatively poor fixing effect of the photovoltaic screen due to the limited vacuum adsorption area when processing the photovoltaic screen with larger size, effectively improving the limiting and fixing effect of photovoltaic screens of different sizes, and thus meeting the higher requirements for the production efficiency of the photovoltaic screen.

[0055] The present application also provides a processing device, which includes the photovoltaic screen limiting device in the above embodiment; the processing equipment also includes a horizontal transfer device, which can drive the photovoltaic screen limiting device to move in a horizontal direction.

[0056] The horizontal transfer device is provided with a mounting mechanism and a two-dimensional motion platform, one side of the mounting mechanism is connected to the photovoltaic screen limiting device, and the other side of the mounting mechanism is connected to the two-dimensional motion platform.

[0057] The division of the modules in the above photovoltaic screen limiting device is only for illustration. In other embodiments, the photovoltaic screen limiting device can be divided into different modules as needed to complete all or part of the functions of the above photovoltaic screen limiting device.

[0058] The photovoltaic screen limiting device and processing equipment provided in the above-mentioned embodiments can, during the photovoltaic screen scribing and cutting process, have an adsorption mechanism arranged on the supporting mechanism capable of adsorbing the film surface of the photovoltaic screen under the action of vacuum adsorption, thereby realizing position constraint of the end face of the photovoltaic screen close to the middle area, and at the same time, a clamping mechanism arranged on the outside of the adsorption mechanism includes a clamping limiting component and a clamping driving component, and the clamping driving component can drive the side of the photovoltaic screen to abut against the clamping limiting component, thereby realizing position constraint of the side of the photovoltaic screen away from the adsorption mechanism, that is, adding the abutting and clamping effect of the clamping mechanism 30 in the area where the vacuum adsorption effect of the adsorption mechanism is relatively weak, thereby enhancing the position constraint effect on photovoltaic screens with larger sizes, thereby improving the problem of relatively poor fixing effect of the photovoltaic screen due to the limited vacuum adsorption area when processing photovoltaic screens with larger sizes, effectively improving the limiting and fixing effect of photovoltaic screens of different sizes, thereby meeting higher requirements for photovoltaic screen production efficiency, and having important economic value and promotion and practical value.
