[0001] The utility model belongs to the technical field of photovoltaic modules, and particularly relates to a protective device for printing patterns on the frame of a photovoltaic module. Background Art

[0002] A photovoltaic module with printable patterns is a new type of product that combines photovoltaic technology with graphic design. Such a module not only has the power generation function of a traditional photovoltaic module but also can print various patterns on the surface of the module through specific technical means, thereby increasing its aesthetics and artistry. This kind of photovoltaic module has various uses. For example, it can be combined with the building appearance to form a beautiful and practical building-integrated photovoltaic system, or it can be used in public places such as parks and squares, which is both beautiful and practical.

[0003] Printing patterns on a photovoltaic module is not limited to the surface of the battery cells. It can also be printed on the photovoltaic backplane, frame, etc. The frame is a visible part of the photovoltaic module. Printing patterns can increase the recognition and aesthetics of the module. If the patterns on the frame need to be determined after installation (such as customized according to the on-site environment or customer requirements), or if patterns need to be printed on multiple parts of the photovoltaic module, the patterns can be printed on the frame after assembling the photovoltaic module. The methods of pattern printing are diverse. For example, spraying technology can be used, but during the spraying process, other parts of the photovoltaic module (such as the photovoltaic backplane and photovoltaic glass) are easily contaminated by the splashed paint, which can easily affect the appearance and performance of the photovoltaic module. Summary of the Utility Model

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1

[0037] As Figures 1 to 4 shown, the present invention provides a protective device for printing patterns on the frame of a photovoltaic module, including a covering assembly 1 for covering the front and back of the photovoltaic module; the covering assembly 1 includes two covering mechanisms 11 symmetrically distributed, and each covering mechanism 11 includes a driving part 111 and a covering part 112 installed on the driving part 111. The driving part 111 is used to drive the covering part 112 to approach or move away from the photovoltaic module; the two covering parts 112 are respectively used to cover the front and back of the photovoltaic module.

[0038] After the photovoltaic module is assembled, pattern printing treatment is carried out on its frame. Specifically, this treatment process can be completed by an operator, an existing device, or a combination of both. For example, in some cases, this treatment process is completed by means of spraying technology. During operation, the paint is evenly sprayed on the frame surface through a spray gun or a spraying machine to form the required pattern or design. This operation can also be completed by means of other structures or objects (such as templates).

[0039] Before the pattern printing treatment, the covering assembly 1 operates, and the two driving parts 111 are started to drive the two covering parts 112 to cover the front (i.e., the side with photovoltaic glass) and the back (i.e., the side with photovoltaic backplane) of the photovoltaic module respectively, so as to avoid more other parts of the photovoltaic module being contaminated due to the pattern printing treatment; when using spraying technology, due to improper control of the pressure and angle of the spray gun, the sprayed material may fly out in the form of tiny droplets, and these flying droplets are easily attached to the adjacent photovoltaic glass and photovoltaic backplane, causing contamination; while through the setting of the covering assembly 1, the splashed paint can be prevented from contaminating the photovoltaic glass and photovoltaic backplane, preventing these two key surfaces of the photovoltaic module from being contaminated, thereby ensuring the cleanliness of the photovoltaic module during the frame pattern printing process, protecting its appearance and performance from being damaged, and at the same time improving the efficiency and safety of the printing operation.

[0040] Optionally, the driving part 111 is set as a single-axis robot or an existing similar device.

[0041] Optionally, the covering part 112 is set as a plate-like structure and its size is adapted to the photovoltaic glass or the photovoltaic backplane.

[0042] It should be noted that after the two covering parts 112 cover the front and back of the photovoltaic module respectively, on the one hand, the above-mentioned protection function can be achieved; on the other hand, the two covering parts 112 can cooperate to fix the photovoltaic module to prevent it from moving during the printing process; on the third hand, the two covering parts 112 can separate the photovoltaic module from the ground, avoid the photovoltaic module from being polluted by the ground and facilitate the graphic printing on the bottom surface of the frame.

[0043] Embodiment 2

[0044] In this embodiment, driving members 2 are installed at the bottoms of the driving parts 111. The driving members 2 are used to adjust the positions of the corresponding driving parts 111 in the vertical direction, and the two driving members 2 can cooperate to adjust the position of the photovoltaic module in the vertical direction.

[0045] Optionally, the driving member 2 is set as a scissor lift or a similar existing device.

[0046] Through the setting of the driving member 2, the position of the photovoltaic module in the vertical direction can be adjusted, so as to adapt to graphic printing devices of different sizes, facilitate graphic printing on the frame from below the frame, and also facilitate the operation and observation of the operator.

[0047] Embodiment 3

[0048] In this embodiment, covering members 3 are detachably sleeved outside the covering parts 112. The covering members 3 are used to limit the dispersion range of the sprayed material and the dispersion range of the waste gas.

[0049] It should be noted that during the spraying process, various harmful substances will be emitted. These substances constitute the main components of the spraying waste gas, specifically including: volatile organic compounds, including hydrocarbons, alcohols, aldehydes, ketones, ethers, esters, amines, etc.; paint mist. During the spraying process, part of the paint will be suspended in the air in the form of tiny droplets to form paint mist. The paint mist not only pollutes the air, but also adheres to equipment, walls and the ground, increasing the cleaning difficulty; other harmful substances. The spraying waste gas may also contain harmful substances such as heavy metals, dust, acid mist, etc. These substances have potential hazards to human health and the environment.

[0050] Considering the existence of the above waste gas, generally, the present utility model is used in cooperation with existing suction devices and waste gas treatment devices. The suction device recovers the waste gas and then introduces it into the waste gas treatment device, and then the waste gas treatment device processes it.

[0051] Optionally, the covering member 3 is set as a plate-like structure, and an installation hole is provided in the middle thereof. The size of the installation hole is adapted to the size of the covering part 112, and the covering part 112 is placed in the installation hole.

[0052] The covering member 3 can be separated from the covering part 112, and covering members 3 of different sizes can be selected according to actual situations.

[0053] Through the arrangement of the two covering parts 3, the dispersion direction of the waste gas is restricted, so that the waste gas can be recovered in cooperation with the existing suction device.

[0054] When the setting template is used in cooperation with graphic printing equipment such as a spraying machine, the two covering parts 3 can also be used in cooperation to fix the template.

[0055] Example 4

[0056] In this embodiment, a plurality of jacks 31 are provided on the covering part 3;

[0057] It further includes a plurality of support parts 4. The number of the support parts 4 is the same as the number of the jacks 31. Each support part 4 is slidably connected to the inner wall of each jack 31 in a one-to-one correspondence. The support part 4 is used to support the template. The support part 4 can cooperate with the covering part 3 to fix the template. The support part 4 can be separately arranged from the jack 31.

[0058] The use of the template is mentioned above. Here, the template is further described. The template method is often used in the spraying graphics technology. In the specific operation process of the template method, it is necessary to make a template that matches the size of the frame and has the required graphics (multiple separately arranged templates can also be used). The graphic part on the template is usually open, while the non-graphic part is blocked. When making the template, according to the design requirements, use a suitable material (such as metal, plastic or paper) to make the template, and engrave or cut out the required graphics on the template. When using the template, place the template accurately on the surface of the frame to ensure the correct position of the graphics, and then use a spray gun or spraying equipment to evenly spray the paint on the surface of the frame. Due to the blocking effect of the template, the paint will only be sprayed on the graphic part. After the paint dries, remove the template, and the required graphics will appear on the frame. In some cases, it is also possible to set the template to cover a partial area of the frame surface and then spray. After spraying, the surface of the frame is colored, while the area covered by the template is not colored but also forms a pattern. The shape, size, etc. of the template can be adjusted according to the actual situation. The template can also be bonded to a connecting structure such as a connecting rod. When the connecting structure contacts other structures and is supported, the template can also be supported.

[0059] During the spraying process, the template needs to be stably attached to the frame. If the template is placed on the top of the frame, no additional fixation is required. However, when the template is attached to the side wall or bottom wall of the frame, an additional fixing or supporting structure needs to be set.

[0060] The support part 4 is supported by the covering part 3, and it can support the template to achieve stable attachment of the template to the frame. Taking the case where the template is a single one and matches the size of the frame as an example, if the template is attached to the side wall of the frame, only need to move a single support part 4 to make it fit the bottom of the template to support the template.

[0061] It should be noted that when the size of the template matches the frame, the two covering parts 3 can cooperate to fit and fix the template. At this time, the two covering parts 3 cooperate with the supporting part 4 used above; it should be emphasized that when the width of the template is appropriate, that is, when the template contacts the two covering parts 3 after fitting with the frame, the two covering parts 3 can achieve the above-mentioned fixing effect.

[0062] The size of the supporting part 4 can be adjusted according to the actual situation to adapt to templates of different sizes.

[0063] The number, size and distribution of the jacks 31 can all be adjusted according to the actual situation.

[0064] Embodiment 5

[0065] In this embodiment, some of the jacks 31 are arranged at the bottom ends of the two covering parts 3.

[0066] When some of the jacks 31 are arranged at the bottom ends of the two covering parts 3, the corresponding supporting part 4 can support the template that fits with the bottom wall of the frame.

[0067] Multiple jacks 31 can be arranged at the bottom ends of both covering parts 3, so as to adapt to the situation where the bottom wall of the frame fits with multiple separated templates.

[0068] Embodiment 6

[0069] In this embodiment, some of the jacks 31 are arranged at both ends of the two covering parts 3 along their own width direction, and the width direction of the covering part 3 is perpendicular to the vertical direction.

[0070] When some of the jacks 31 are arranged at both ends of the two covering parts 3 along their own width direction, the corresponding supporting part 4 can support the template that fits with the side wall of the frame.

[0071] Multiple jacks 31 can be arranged at both ends of both covering parts 3 along their own width direction, so as to adapt to the situation where the side wall of the frame fits with multiple separated templates.

[0072] Embodiment 7

[0073] In this embodiment, the jacks 31 opened on the same covering part 3 are set as the same group of jacks 31, and the supporting parts 4 slidingly connected to the hole walls of the jacks 31 belonging to the same group are set as the same group of supporting parts 4;

[0074] It further includes two connecting pieces 5, and the two connecting pieces 5 are respectively attached to two groups of supporting parts 4, and the supporting parts 4 belonging to the same group are detachably connected to the same connecting piece 5.

[0075] The arrangement of the connecting piece 5 enables some of the supporting parts 4 to move synchronously, thereby reducing the operation steps and avoiding the need to move several supporting parts 4 one by one in the case of using several templates.

[0076] Each of the support parts 4 belonging to the same group is detachably connected to the same connecting member 5, and this connecting member 5 is the connecting member 5 closest to it among the two connecting members 5.
