Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module production technology, specifically to a film strip pulling mechanism. Background Technology

[0002] Applying reflective film strips to the busbar of a photovoltaic module can reflect light incident on the surface of the busbar to other parts of the solar cell for absorption, thereby increasing power generation efficiency.

[0003] In the prior art, the reflective film strips affixed to the surface of the busbar are provided by a film roll. A film puller holds one end of the reflective film strip and pulls it out of the film roll. It is then cut by a cutter. The part of the reflective film strip not held by the film puller is adsorbed by the film carrier platform. The film puller releases the end of the reflective film strip above the film carrier platform. As the released end falls onto the film carrier platform, it naturally curls due to internal stress and cannot be laid flat on the surface of the film carrier platform, affecting the subsequent film strip transfer process.

Detailed Implementation

[0026] The technical solution and effects of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] In the description of this utility model, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this utility model, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them.

[0028] like Figures 1-4As shown, this utility model provides a film strip pulling mechanism for preparing reflective film strips attached to the busbar in photovoltaic modules. It includes a film pulling hand 100, a film carrier stage 200, a cutter assembly 300, and a vertical pressing assembly 400. Along the length of the film strip, the film pulling hand 100 is reciprocally positioned above the film carrier stage 200. The film carrier stage 200 has a cutter assembly 300 and a vertical pressing assembly 400 at one end or both ends. The cutter assembly 300... 0 is located between the film pulling hand 100 and the vertical pressing film assembly 400; the film carrier stage 200 is provided with a plurality of adsorption holes 210, which are linearly spaced along the length of the film strip; the film pulling hand 100 includes a moving plate 110 and a clamp 120 disposed on the moving plate 110, the clamp 120 and the cutter assembly 300 are respectively disposed in correspondence; the moving plate 110 is provided with a film spreading member 500, which is located at the front end of the clamp 120.

[0029] The movable plate 110 is connected to the drive mechanism and can reciprocate along the length of the film strip. The clamp 120 is used to hold the end of the film strip, and the end of the film strip held by the clamp 120 moves with the movable plate 110, which can pull out the film strip. The cutter assembly 300 is used to cut the pulled-out film strip, and the vertical pressing assembly 400 is used to press and fix the film strip before cutting, which is beneficial for the cutter assembly 300 to cut the film strip. After the film strip is cut, the film pulling hand 100 pulls the film strip to the corresponding position on the film carrier 200. At this time, the part of the film strip not held by the clamp 120 falls onto the film carrier 200 under the influence of gravity and is attracted by the adsorption hole 210. After the clamp 120 opens to release the end of the film strip, the film spreading member 500 spreads the end of the film strip so that it is attracted by the adsorption hole 210 and will not curl again. The film carrier 200 can carry one long film strip or multiple short film strips at the same time.

[0030] like Figure 4 As shown, in an optional embodiment of this utility model, the film spreading member 500 is an air blowing block, which has downward-facing air blowing holes. The air blowing block has a gas channel, one end of which is connected to an external air source, and the other end is connected to the air blowing holes. After the clamp 120 releases the end of the film strip, air is blown through the air blowing holes. The airflow can flatten the end of the film strip onto the film carrier stage 200, where it is then adsorbed by the adsorption holes.

[0031] In another optional embodiment of this utility model, the film spreading component 500 is a height-adjustable sponge roller. The sponge roller is sleeved on a rotating shaft, and the rotating shaft can be driven by a cylinder to raise and lower, thereby raising and lowering the sponge roller. The cylinder can be fixed to the moving plate 110 by a cylinder seat. After the clamp 120 releases the end of the film strip, the sponge roller moves down to press the end of the film strip and flatten it on the film carrier stage 200, where it is then adsorbed by the adsorption holes.

[0032] In an optional embodiment of this utility model, both ends of the film carrier stage 200 are provided with a cutter assembly 300 and a vertical film pressing assembly 400. Each clamp 120 includes an upper clamping jaw 121 and a lower clamping jaw 122. The middle part of the upper clamping jaw 121 is hinged to the moving plate 110, and one end of the lower clamping jaw 122 is fixed to the moving plate 110. A bidirectional cylinder 130 is also fixed on the moving plate 110. The bidirectional cylinder 130 is located between the two clamps 120, and the two piston rods of the bidirectional cylinder 130 are respectively hinged to the non-clamping ends of the two upper clamping jaws 121. The bidirectional cylinder 130 can sequentially control the two clamps 120 to open or close, so that the film pulling hand 100 can pull out the film strip from two directions, thereby improving the film strip pulling efficiency.

[0033] In an optional embodiment of this utility model, a limiting plate 220 is provided on the film carrier stage 200. The limiting plate 220 is located on both sides of the adsorption hole 210. When the film puller 100 pulls the cut film strip, the part of the film strip that is not clamped falls between the limiting plates 220 on both sides of the adsorption hole 210, which can prevent the film strip from shifting in its width direction.

[0034] In an optional embodiment of this utility model, the film strip pulling mechanism further includes a rotary film pressing assembly 600. The rotary film pressing assembly 600 includes a first mounting base 610, a first cylinder 620, and a rotary pressing plate 630. The first mounting base 610 is fixed to the film carrier stage 200. The first cylinder 620 is fixed on the first mounting base 610. The middle part of the rotary pressing plate 630 is hinged to the first mounting base 610, and the piston rod of the first cylinder 620 is hinged to one end of the rotary pressing plate 630. The first cylinder 620 can drive the rotary pressing plate 630 to rotate, so as to press it against the film carrier stage 200 or separate it from the film carrier stage 200. Before the clamp 120 releases the film strip, the first cylinder 620 can drive the rotary pressing plate 630 to press the film strip. After the film strip is fixed, the clamp 120 releases the film strip, and the film strip will not move in its length direction.

[0035] like Figure 5 As shown, in an optional embodiment of this utility model, the cutter assembly 300 includes a second mounting base 310, a second cylinder 320, an upper cutter 330, and a lower cutter 340. The second mounting base 310 is reciprocating along the length of the film strip. The second cylinder 320 and the lower cutter 340 are fixed on the second mounting base 310. The piston rod of the second cylinder 320 is connected to the upper cutter 330, which is located above the lower cutter 340. The second mounting base 310 is provided with a first film strip channel 311. The first film strip channel 311 is used for the film strip to pass through. The second cylinder 320 drives the upper cutter 330 to move towards the lower cutter. The upper cutter 330 and the lower cutter 340 cooperate to cut the film strip. Since the second mounting base 310 is reciprocating along the length of the film strip, after cutting the film strip, the second mounting base 310 moves backward to expose the end of the next section of the film strip, which is convenient for the film puller 100 to hold.

[0036] like Figure 6 and 7 As shown, in an optional embodiment of this utility model, the vertical film pressing assembly 400 includes a base plate 410, a third mounting base 420, a third cylinder 430, and a pressing block 440. The third mounting base 420 is vertically fixed on the base plate 410, and the third cylinder 430 is fixed on the third mounting base 420. The piston rod of the third cylinder 430 is connected to the pressing block 440, which faces the base plate 410. The third mounting base 420 is provided with a second film strip channel. The second film strip channel is used for the film strip to pass through. The third cylinder 430 drives the pressing block 440 to move downward, which can press the film strip onto the base plate 410, thus fixing it before the cutter assembly 300 cuts the film strip.

[0037] In an optional embodiment of this utility model, a support 450 is provided on the base plate 410, and a rotatable roller 460 is provided on the support 450. The roller 460 is located on one side of the entrance of the second membrane strip channel. The membrane strip passes under the roller 460, and the roller 460 is used to limit the upward movement of the membrane strip. Further, a membrane strip guide groove 411 is formed on the edge of the base plate 410, and the roller 460 is located above the membrane strip guide groove 411. An annular groove 461 is formed on the circumferential surface of the roller 460. The membrane strip guide groove 411 is an inclined groove to facilitate the insertion of the membrane strip, and the membrane strip is located in the annular groove 461 to limit the movement of the membrane strip in its width direction.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the present utility model.
