Description

Technical Field

[0001] The utility model relates to the field of photovoltaic component production, in particular to a spacing adjustment mechanism and a film pasting device. Background Art

[0002] Photovoltaic modules are usually packaged by a backplane, a lower layer of adhesive film, a battery string group, an upper layer of adhesive film and a glass plate. There are gaps between two adjacent battery cells in a battery string group and between two adjacent battery strings. The light energy irradiated into these gaps is difficult to be directly absorbed or utilized. In order to improve the utilization rate of light energy, the industry uses reflective film strips on the backplane at positions corresponding to the gaps between cells and strings. The reflective film strips reflect the light energy irradiated into the above gap positions onto the glass plate, and then reflect it onto the battery cells through the glass plate, so as to fully utilize the light energy in the gaps.

[0003] The reflective film strips are applied by a film laminating machine, which includes multiple film laminating heads arranged side by side and spaced apart. The multiple film laminating heads apply the reflective film strips released from multiple rolls to the backboard at the same time. For backboards of different sizes, the reflective film strips are applied at different positions, and the spacing between the film laminating heads needs to be adjusted each time the backboard pattern is changed. The existing film laminating head spacing adjustment mechanism has a spacing adjustment drive component corresponding to each film laminating head. The excessive number of spacing adjustment drives makes the overall structure of the spacing adjustment mechanism more complicated and costly. Utility Model Content

The translation driving assembly 2 is also used to drive the first mounting plate 5 locked and connected by the locking assembly 3 to move to a specified position; the positioning assembly 4 is connected to the first mounting plate 5 in a one-to-one correspondence, and the positioning assembly 4 is used to position the first mounting plate 5 on the back plate 1 after the corresponding first mounting plate 5 moves to the specified position.

[0045] Optionally, a first slide rail extending along a first horizontal direction is installed on the back plate 1, and each first mounting plate 5 is slidably mounted on the first slide rail via a slider.

[0046] When the distance between the film laminating heads needs to be adjusted, the film laminating heads can be installed one-to-one on the first mounting plate. The optional working process of the distance adjustment mechanism in the embodiment of the present application is as follows:

[0047] First, the locking assembly 3 is driven by the translation driving assembly 2 to move to the first mounting plate 5 at the position to be adjusted, and the locking assembly 3 is controlled to be locked and connected with the first mounting plate 5;

[0048] Next, the translation drive assembly 2 drives the first mounting plate 5 to move, so as to adjust the position of the film laminating head installed on the first mounting plate 5. After the adjustment is in place, the positioning assembly 4 corresponding to the first mounting plate 5 is controlled to position the first mounting plate 5 on the back plate 1.

[0049] Finally, the locking assembly 3 is unlocked from the first mounting plate 5 and driven by the translation driving assembly 2 to move to the first mounting plate 5 at the next position to be adjusted.

[0050] By repeating the above operation, the position adjustment of all the first mounting plates 5 can be realized, that is, the position adjustment of all the film laminating heads can be realized.

[0051] It can be seen that the spacing adjustment mechanism provided in the present application can complete the spacing adjustment of all film laminating heads through only one translation drive component, and has a simple structure and low cost.

[0052] It should be noted that since the spacing adjustment of the film heads is only required when the back plate pattern is changed, the back plate pattern is not changed frequently during the actual production process, so the spacing adjustment mechanism of the present application will not affect the production efficiency.

[0053] like Figures 1 to 3As shown, optionally, the translation drive assembly 2 includes a motor 21, a gear 22, a rack 23 and a movable plate 24, wherein: the movable plate 24 is slidably mounted on the back plate 1 along a first horizontal direction; the rack 23 is mounted on the back plate 1 and extends along the first horizontal direction; the motor 21 is mounted on the movable plate 24, the gear 22 is mounted on the driving end of the motor 21 and meshes with the rack 23; and the locking assembly 3 is mounted on the movable plate 24.

[0054] like Figures 1 to 3 As shown, optionally, the locking assembly 3 is arranged above each first mounting plate 5, and the locking assembly 3 includes a first telescopic drive member 31 and a first plug 32. The upper end of each first mounting plate 5 is provided with a first slot 51 that cooperates with the first plug 32, and the first plug 32 is installed at the driving end of the first telescopic drive member 31; the first telescopic drive member 31 is used to drive the first plug 32 to rise to disengage from the first slot 51, so that the locking assembly 3 is unlocked from the first mounting plate 5 to be adjusted; the first telescopic drive member 31 is also used to drive the first plug 32 to descend to abut against the first slot 51, so that the locking assembly 3 is locked and connected to the first mounting plate 5 to be adjusted.

[0055] Optional, such as Figure 2 As shown, the first slot 51 is a V-shaped slot with an opening facing upward. The design of the V-shaped slot can ensure that the first plug 32 can be inserted smoothly and can be centered after insertion, thereby improving the position adjustment accuracy of the first mounting plate 5.

[0056] Optional, such as Figure 2 As shown, the first telescopic driving member 31 includes a first horizontal support plate 311, a first transmission plate 312 and a first cylinder 313. The first horizontal support plate 311 is fixedly mounted on the driving end of the translation driving assembly 2, the first cylinder 313 is mounted on the first horizontal support plate 311, the first transmission plate 312 is arranged below the first horizontal support plate 311 and is drivingly connected to the first cylinder 313, and a guide rod is used to implement sliding guidance between the first transmission plate 312 and the first horizontal support plate 311, and the first plug 32 is mounted on the first transmission plate 312.

[0057] The first plug 32 is driven by the first telescopic driving member 31 to extend into or out of the first slot 51 on the first mounting plate 5, so as to lock or unlock the first mounting plate 5. The structure is simple, easy to implement and low in cost.

[0058] like Figure 3As shown, optionally, the positioning component 4 includes a mounting frame 41 and an electromagnet 42, and the spacing adjustment mechanism also includes a magnetic plate 8, wherein: the mounting frame 41 and the first mounting plate 5 are respectively arranged on opposite sides of the back plate 1, and the back plate 1 is provided with a first avoidance channel 11 for the lower end of the mounting frame 41 to pass through, and the first avoidance channel 11 extends along the first horizontal direction; the lower end of the mounting frame 41 is fixedly connected to the first mounting plate 5 after passing through the first avoidance channel 11, and the upper end of the mounting frame 41 is slidably connected to the back plate 1; the electromagnet 42 is installed on the mounting frame 41, and the magnetic plate 8 is installed on the back plate 1 and arranged opposite to each electromagnet 42, and the magnetic plate 8 extends along the first horizontal direction, and the electromagnet 42 is used to adsorb the magnetic plate 8 after the corresponding first mounting plate 5 moves to the specified position, so as to position the first mounting plate 5 on the back plate 1.

[0059] When the first mounting plate 5 is adjusted into place, the corresponding electromagnet 42 is energized, and the electromagnet 42 can adsorb the magnetic plate 8 to achieve positioning of the first mounting plate 5 and prevent the first mounting plate 5 from deviating from the specified position; when the position of the first mounting plate 5 needs to be adjusted, the corresponding electromagnet 42 is powered off to release the electromagnet 42 from adsorbing the magnetic plate 8. The above-mentioned positioning component 4 has a simple structure, is easy to implement, and has low cost.

[0060] like Figure 3 As shown, optionally, the positioning component 4 also includes an elastic component, and the electromagnet 42 is installed on the mounting frame 41 through the elastic component, and the elastic component is configured to elastically press the electromagnet 42 against the magnetic attraction plate 8.

[0061] By setting an elastic component, the electromagnet 42 is always elastically pressed against the magnetic attraction plate 8. When an unexpected power outage causes the electromagnet 42 to be unable to adsorb the magnetic attraction plate 8, the first mounting plate 5 can be positioned on the back plate 1 by relying on the pressure of the elastic component. When the position of the first mounting plate 5 needs to be adjusted, the translation drive component 2 can overcome the pressure of the elastic component and drive the first mounting plate 5 to translate.

[0062] like Figure 3 As shown, optionally, the elastic component includes at least two guide columns 43 and a push plate 44, each guide column 43 is horizontally arranged, one end of each guide column 43 is slidably connected to the mounting frame 41, and the other end of each guide column 43 is fixedly connected to the push plate 44, and a spring 45 is mounted on the guide column 43 between the push plate 44 and the mounting frame 41, and the electromagnet 42 is installed on the push plate 44, and the spring 45 presses the electromagnet 42 against the magnetic attraction plate 8 through the push plate 44.

[0063] Usually, each laminating head on the laminating machine is equipped with a material roll, which continuously supplies reflective film strips to the laminating head. In order to ensure the tension of the reflective film strips, a film strip tensioning rod is usually set between each material roll and the corresponding laminating head. The film strips released by the material roll bypass the film strip tensioning rod and enter the laminating head. When adjusting the spacing of the laminating heads, if the film strip tensioning rod is not adjusted synchronously at the same time, the film strips may not be tensioned or deviate, affecting the smooth laminating of the reflective film strips.

[0064] In order to solve the above problems, the spacing adjustment mechanism of the embodiment of the present application also includes a plurality of second mounting plates 6 arranged above the first mounting plate 5 and corresponding to the first mounting plate 5 one by one, the second mounting plates 6 are connected to the corresponding first mounting plates 5 through a positioning assembly 4, and each second mounting plate 6 is slidably mounted on the back plate 1 along the first horizontal direction; the locking assembly 3 is located between the first mounting plate 5 and the second mounting plate 6, and the locking assembly 3 is used to synchronously lock or unlock the first mounting plate 5 to be adjusted and the corresponding second mounting plate 6.

[0070] The first plug 32 and the second plug 34 are synchronously driven to extend and retract by the first telescopic driving member 31 and the second telescopic driving member 33, so as to realize synchronous locking or unlocking of the first mounting plate 5 and the second mounting plate 6, which has a simple structure, is easy to realize and has low cost.
