Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic module production technology, and in particular relates to a film strip material box, a film strip feeding unit, and a film strip placement device. [Background Technology]

[0002] Photovoltaic modules are composed of crystalline silicon solar cells, tempered glass, and encapsulation materials stacked in different sequences and then laminated to form a laminate. During lamination, heating melts the encapsulant film on the upper and / or lower layers of the busbar, positioning one end of the busbar within the laminate. After lamination, air bubbles (missing encapsulant film) can appear, affecting module quality. To address this, encapsulant strips are placed at locations prone to bubble formation, facilitating re-encapsulation during lamination. Previously, these placement operations were often performed manually, which was inefficient and costly.

[0003] To address the aforementioned issues and achieve a high degree of automation in the production line, a specialized adhesive strip placement device has been designed. For example, the adhesive strip material box, adhesive strip feeding unit, and adhesive strip placement device disclosed in Chinese Patent Publication No. CN217655848U include a glass transfer and positioning device, a feeding device, and a transfer device. The feeding device includes an adhesive strip feeding box. However, in this solution, the adhesive strip feeding box can only store adhesive strips of a fixed size. If adhesive strips of different sizes need to be placed, adhesive strip feeding boxes of different sizes need to be prepared. Photovoltaic modules of the same size may require adhesive strips of different sizes, not to mention that photovoltaic modules themselves come in various sizes. Therefore, if the adhesive strip feeding box can only store adhesive strips of a fixed size, a large number of adhesive strip feeding boxes need to be prepared, which is not only costly but also occupies a large amount of space.

[0004] Therefore, it is necessary to provide a film strip material box, a film strip feeding unit, and a film strip placement device to solve the above-mentioned technical problems. [Utility Model Content]

After adjusting the position of the first enclosure 321, tighten the first fastener to adjust the length of the receiving cavity 33.

[0060] Method 2: Adjust the width of the receiving cavity 33 to accommodate adhesive strips of different widths. The method for adjusting the width of the receiving cavity 33 is as follows: Loosen the second fastener, move the position of the second enclosure 322 back and forth so that the second mounting hole 3223 corresponds to another second positioning hole. After adjusting the position of the second enclosure 322, tighten the second fastener to adjust the width of the receiving cavity 33.

[0061] Method 3: Simultaneously adjust the length and width of the receiving cavity 33 to accommodate adhesive strips of different lengths and widths. The method for adjusting the length and width of the receiving cavity 33 is as follows: Loosen the first fastener, move the position of the first enclosure 321 left and right so that the first mounting hole 3213 corresponds to another first positioning hole. After adjusting the position of the first enclosure 321, tighten the first fastener. At the same time, loosen the second fastener, move the position of the second enclosure 322 back and forth so that the second mounting hole 3223 corresponds to another second positioning hole. After adjusting the position of the second enclosure 322, tighten the second fastener to achieve the adjustment of the length and width of the receiving cavity 33.

[0062] The adhesive strip feeding unit 3 also includes a first driving member 36 and a movable seat 37 driven by the first driving member 36 to move along the X or Y direction. The adhesive strip material box 3a is detachably mounted on the movable seat 37. Specifically, the base plate 31 is detachably mounted on the movable seat 37. The movable seat 37 is mounted on the frame 6 via a slide rail slider. The first driving member 36 is a cylinder or a motor.

[0063] The movable seat 37 is provided with a receiving groove 371 for accommodating the base plate 31. The receiving groove 371 is provided with a positioning pin 372 for positioning the base plate 31. The width of the receiving groove 371 is set in the same shape as the width of the base plate 31. After the base plate 31 is positioned in the receiving groove 371, the base plate 31 is fixed to the movable seat 37 by the third fastener 38. If it is necessary to remove the base plate 31, loosen the third fastener 38 and then remove the base plate 31 from the receiving groove 371, so that the adhesive strip box 3a can be removed.

[0064] In this embodiment, the third fastener 38 is set as an indexing pin. In other embodiments, the third fastener can be set as a bolt, screw, pin or other fastening structure, and there is no limitation here.

[0065] The handling and placement mechanism 4 includes an XZ axis drive module 41 and a handling frame 42 that moves along the XZ direction driven by the XZ axis drive module 41. The bottom of the handling frame 42 is provided with a suction cup unit 43 for adsorbing adhesive strips.

The XZ axis drive module 41 includes a first motor 411, a first support plate 412 that moves in the X direction driven by the first motor 411, and a second motor 413 mounted on the support plate. The handling frame 42 moves in the Z direction driven by the second motor.

[0066] Since adhesive strips need to be placed on the two short sides of the photovoltaic module, this embodiment provides two adhesive strip feeding units 3, located on the left and right sides of the module conveyor line 1, respectively. To improve placement efficiency, two handling and placement mechanisms 4 are provided above the module conveyor line 1. Each handling mechanism 4 is equipped with a suction cup unit 43. The two handling and placement mechanisms 4 work simultaneously, respectively adsorbing the adhesive strips on the corresponding adhesive strip feeding units 3 and placing them on the two short sides of the photovoltaic module. Since the adhesive strip cassette 3a needs to be placed manually onto the adhesive strip feeding unit 3, a safety light curtain 7 is provided on the outside of the adhesive strip feeding unit 3 of the frame 6 to prevent personnel from entering the placement machine and getting injured. If personnel enter the placement machine, the safety light curtain 7 will trigger an alarm to prevent injury.

[0067] In other embodiments, only one adhesive strip feeding unit 3 and one transport and placement mechanism 4 may be provided. However, two suction cup units 43 are provided on the transport frame 42, which sequentially pick up two adhesive strips from one adhesive strip feeding unit 3 and transport and place them onto the two short sides of the photovoltaic module. If multiple adhesive strips need to be applied, multiple suction cup units 43 can be provided on the transport frame 42, which sequentially pick up multiple adhesive strips from one adhesive strip feeding unit 3 and transport and place them onto the photovoltaic module. The number and position of the adhesive strip feeding unit 3 and the transport and placement mechanism 4 are not limited and can be adjusted according to the actual processing efficiency and the size of the placement machine.

[0068] The module conveyor line 1 is driven by a motor to rotate the shaft, which in turn drives the belt to transport the photovoltaic modules. It is equipped with four parallel belts to improve the stability of the transport. Two or three belt lines can also be set, depending on the actual situation, and there is no limitation here.

[0069] The front end of the component conveying line 1 is equipped with a blocking module 5 to prevent the photovoltaic modules from being conveyed forward. The blocking module 5 includes a blocking component 51 that blocks the photovoltaic modules and a blocking cylinder 52 that drives the blocking component 51 to rotate or lift.

[0070] In this embodiment, two sets of alignment modules 2 are provided and located on the left and right sides of the module conveyor line 1 to align the two opposite sides of the photovoltaic module. The alignment module 2 includes an alignment cylinder 21, a moving rod 22 driven by the alignment cylinder 21 to move closer to or away from the photovoltaic module, and an alignment wheel 23 fixed on the moving rod 23.

[0071] In other embodiments, a correction component is also provided at the rear end of the component conveyor line 1. The correction component is existing technology and can be designed using existing technology, so it will not be described in detail here.

[0072] In order to increase the support area of ​​the module conveying line 1, support wheels 8 for supporting photovoltaic modules are also provided at both ends of the module conveying line 1.

[0073] When the film strip box, film strip feeding unit and film strip placement device 100 provided in this solution are used, after the photovoltaic module is transported to the module conveying line 1, the blocking module 5 blocks the photovoltaic module from continuing to be transported forward. The aligning cylinders 21 on both sides of the photovoltaic module drive the aligning wheel 23 to approach the side of the photovoltaic module and align the photovoltaic module. At the same time, the conveying and placement mechanism 4 on both sides starts to work. The XZ axis drive module 41 drives the conveying frame 42 to move to the film strip feeding unit 3. The suction cup unit 43 adsorbs the film strip. The XZ axis drive module 41 drives the conveying frame 42 to move to the short side of the photovoltaic module and place the film strip on the short side of the photovoltaic module.

[0074] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
