Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component processing, in particular to a battery stringing platform and a battery stringing device. Background Art

[0002] In the production process of photovoltaic module battery strings, a method of using adhesive strips to attach welding tapes to pre-fix the battery cells is currently proposed. This method requires that the battery cells, welding tapes and corresponding adhesive strips be placed one by one on the stringing platform and then gradually stringed together. After the corresponding battery cell assembly is placed on the stringing platform, in order to prevent the sliding position of the battery cell assembly from shifting, a corresponding adsorption structure needs to be set on the stringing platform to fix the battery cell assembly and the welding tape and adhesive strip parts thereon. The traditional adsorption method is achieved by pumping and vacuuming. However, in order to ensure the adsorption effect, the number and setting method of the pumps are relatively cumbersome, resulting in increased costs. However, using a small number of pumps makes it difficult to achieve good adsorption of the battery cell areas of each part, that is, it is difficult to ensure a good adsorption effect.

In the drawings, the thickness of regions and layers are exaggerated for clarity. The same reference numerals in the drawings represent the same or similar structures, and thus their detailed description will be omitted.

[0026] The described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention.

In other cases, known structures, materials or operations are not shown or described in detail to avoid blurring the various aspects of the present invention.

[0027] The following example describes a battery stringing platform and a battery stringing device of the present utility model. This example is only a part of the embodiments of the present utility model, but the protection scope of the present utility model is not limited to this. All other embodiments obtained by ordinary technicians in this field without creative work should be included in the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 7 According to an embodiment of the utility model, a battery stringing platform is provided, including a support plate 1, which serves as a mounting carrier for the upper components. The support plate 1 is provided with a plurality of vacuum generating components 2 along its length extension direction, and each of the vacuum generating components 2 is provided with an adsorption plate 3, that is, in the utility model, one adsorption plate 3 is only provided with one vacuum generating component 2. For details, see Figure 4 and Figure 5As shown, the vacuum generating assembly 2 includes a mounting plate 21 and an air inlet flat nozzle 22 and an air outlet flat nozzle 23 assembled in the mounting plate 21, the air outlet end face of the air inlet flat nozzle 22 is opposite to the air inlet end face of the air outlet flat nozzle 23 and is spaced apart to form a negative pressure adsorption area, a negative pressure port 211 connected to the negative pressure adsorption area is formed on the mounting plate 21, the adsorption plate 3 is assembled on the top surface of the mounting plate 21 and a negative pressure cavity 100 is formed between the two (that is, the adsorption plate 3 and the mounting plate 21), the negative pressure port 211 is connected to the negative pressure cavity 100, and an adsorption hole is formed on the top surface of the adsorption plate 3, it can be understood that the flow cross-sections of the aforementioned air inlet flat nozzle 22 and the air outlet flat nozzle 23 are both rectangular The length and width of the rectangle are reasonably selected according to the corresponding application conditions. Of course, when selecting the length and width of the rectangle, the negative pressure effect formed by the vacuum generator in the negative pressure generating area should also be taken into account. The specific size of the aforementioned rectangle can be reasonably designed in combination with experiments. In order to achieve the vacuum negative pressure effect, the aforementioned air inlet flat nozzle 22 has an air inlet flat mouth with a flow area gradually shrinking along the first direction (not marked in the figure), and the air outlet flat nozzle 23 has an air outlet flat mouth with a flow area gradually expanding along the first direction (not marked in the figure), so that the vacuum generating component 2 in the utility model can use the Bernoulli principle to achieve the vacuum negative pressure effect. The aforementioned first direction can specifically be a horizontal direction perpendicular to the length extension direction of the support plate 1.

[0029] In this technical solution, since the air inlet flat nozzle 22 and the air outlet flat nozzle 23 are both flat structures, the negative pressure generating area formed can be a larger rectangular area, so that only one vacuum generating device of the utility model can be used to achieve adsorption of a larger length or width for an adsorption object with a certain length (such as rubber strips and / or welding strips, battery cells), without the need to configure multiple suction pumps in the prior art to achieve multi-point adsorption of larger-sized adsorption objects. The structural design is simple and the manufacturing cost of the mechanism is low.

[0030] In a preferred embodiment, the vacuum generating assembly 2 further includes a flat nozzle mounting seat 25, the flat nozzle mounting seat 25 forms a flat nozzle mounting hole (not marked in the figure) penetrating the first side and the second side thereof along the first direction, the air inlet flat nozzle 22 is assembled on the upstream side of the flat nozzle mounting hole, the air outlet flat nozzle 23 is assembled on the downstream side of the flat nozzle mounting hole, the flat nozzle mounting seat 25 further includes a third side between the first side and the second side, the third side is formed with a through hole connected to the flat nozzle mounting hole, the through hole is arranged opposite to the negative pressure port 211. In this technical solution, the flat nozzle mounting seat 25 serves as a mounting carrier for the air inlet flat nozzle 22 and the air outlet flat nozzle 23, and can lock the relative positional relationship between the two. At the same time, a corresponding fixed connection structure is also formed on the flat nozzle mounting seat 25, such as a threaded connection structure or a snap connection structure, etc., to facilitate assembly. In some embodiments, the air inlet flat nozzle 22 is entirely inserted into the flat nozzle mounting hole, and the air inlet portion of the air outlet flat nozzle 23 is inserted into the flat nozzle mounting hole.

[0031] The aforementioned mounting plate 21 is also constructed with an air intake chamber 2101 and an air exhaust chamber 2102, wherein the air intake chamber 2101 is located on the upstream side of the air intake flat nozzle 22, and is connected to the exhaust port of an external pressure air source (such as a compressor) through an air intake joint 24, and the exhaust chamber 2102 is located on the downstream side of the air outlet flat nozzle 23, and is provided with a corresponding silencer grille to reduce the exhaust noise of the air outlet flat nozzle 23 in a deflecting manner.

[0032] See Figure 4 As shown, a groove 33 is formed on the bottom surface of the adsorption plate 3, and the negative pressure port 211 is located in the area corresponding to the groove 33. A sealing ring 213 is clamped between the notch end surface of the groove 33 and the bottom surface of the adsorption plate 3. The sealing ring 213 can specifically be a rubber sealing ring to ensure the sealing effect of the negative pressure chamber 100.

[0033] In some embodiments, the top surface of the adsorption plate 3 has a solder strip accommodating groove 31 extending along the length extension direction of the support plate 1, and the solder strip accommodating groove 31 passes through both ends of the adsorption plate 3. The solder strip accommodating groove 31 can accommodate the solder strip pre-positioned on the battery cell, thereby ensuring the stable positioning of the battery cell assembly.

[0034] See Figure 6As shown, in some embodiments, the adsorption holes include a plurality of first adsorption holes 321 formed in the solder strip receiving groove 31, and each of the first adsorption holes 321 is spaced apart in the length direction of the solder strip receiving groove 31, so as to achieve reliable adsorption and positioning of the rubber strip pasted on the outside of the solder strip; and / or, the adsorption holes include a plurality of second adsorption holes 322 formed in the area between two adjacent solder strip receiving grooves 31, and each of the second adsorption holes 322 is spaced apart in the length direction of the adsorption plate, so as to achieve reliable adsorption and positioning of the battery cell and the rubber strip thereon.

[0035] See Figure 1 and Figure 2 As shown, the adsorption plate 3 includes a first adsorption plate 301 and a second adsorption plate 302, wherein the length of the first adsorption plate 301 (that is, the dimension in the length extension direction of the support plate 1) is greater than the length of the second adsorption plate 302, and the first adsorption plate 301 and the second adsorption plate 302 are alternately arranged in the length extension direction of the support plate 1, and the adsorption holes also include a plurality of third adsorption holes 323, and the third adsorption holes 323 are located on the top surface area at both ends of the length of the first adsorption plate 301.

[0036] In this technical solution, the length of the first adsorption plate 301 is greater than that of the second adsorption plate 302, and the third adsorption holes 323 are respectively arranged at the two end regions of the length of the first adsorption plate 301, so that the third adsorption holes 323 can be used to reliably adsorb the shading strips at both ends of the battery cell (the aesthetic tape used to fill the blank space between the battery cells) . It should be noted that the aforementioned first adsorption hole 321, the second adsorption hole 322 and the third adsorption hole 323 are all connected to the same negative pressure chamber 100.

[0037] Since there is an error in the spacing between battery cells when they are placed, and the error of a single cell is usually between 0.5 and 2 mm, the position of the shading strip is easily offset when multiple cells are placed. The shading strip is adsorbed by an adsorption groove, but in order to improve the adsorption effect, a number of vacuum adsorption holes (i.e., the third adsorption holes 323) are opened in the adsorption groove corresponding to the shading strip area to communicate with the negative pressure chamber 100, thereby ensuring good adsorption capacity of the shading strip adsorption area. However, in order to cover the shading strip area with the adsorption holes when fewer third adsorption holes 323 are opened, in some embodiments, the third adsorption holes 323 are staggered left and right along the width direction of the first adsorption plate 301 to ensure that when the shading strip is in different positions, at least one column of adsorption holes in these areas can act on the shading strip.

[0038] In some embodiments, a heating element 41 is further provided in the mounting plate 21, and the heating element 41 is used to heat the mounting plate 21, so as to achieve heating of the rubber strip, improve the viscosity of the rubber strip, and make the bonding between the rubber strip and the battery cell more firmly, especially when the rubber strip is made of EVA material, the aforementioned heating element 41 can ensure its bonding effect on the battery cell. In a specific embodiment, the heating element 41 is an electric heating tube, which is inserted into the mounting plate 21 perpendicular to the length extension direction of the support plate 1 and is arranged horizontally. The use of the electric heating tube has high heating efficiency and the structure and control are relatively simple. In another preferred embodiment, the mounting plate 21 is also provided with a temperature detection component (not shown in the figure), such as a temperature sensor, so as to be able to detect the temperature in real time to achieve the regulation of the platform temperature.

[0039] The utility model also provides a battery string device, see Figure 7 As shown, it includes a battery stringing platform 200, and the battery stringing platform 200 is the above-mentioned battery stringing platform. The battery stringing device also includes a platform moving drive component 300. The battery stringing platform 200 has two groups. The platform moving drive component 300 is used to drive each group of the battery stringing platforms 200 to independently lift or independently reciprocate to form an alternating operation of the battery stringing platform 200. Specifically, each battery stringing platform 200 can be lifted and lowered on the corresponding track and moved left and right (in Figure 7 The positions shown are for reference only) so that it can improve the continuity of battery stringing and improve work efficiency.

[0040] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
