Description

Technical Field

[0001] This specification relates to the field of automation equipment technology, and in particular to an EVA small material placement device. Background Technology

[0002] Solar cells are the most important production link in the photovoltaic industry. EVA is a kind of encapsulant film that is laid on a glass plate and sandwiches the solar cells in the solar panel. It plays a protective role such as insulation, waterproofing, aging resistance, and supporting the cells. The laying accuracy of EVA directly affects the quality of solar cell modules.

[0003] In the manufacturing process of photovoltaic modules, there is a gap in the EVA film at the lead-in location to allow the lead to pass through and be exposed. To fill the gap in the EVA film, small pieces of EVA insulation are usually used to cover the gap to prevent the molten material from being squeezed out of the gap after the film melts during the lamination process.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] Please see Figures 1 to 5 This application provides an EVA small material placement device, including a first mounting plate 1 and a plurality of placement mechanisms 5.

[0034] The first mounting plate 1 is horizontally positioned. A first slide rail 2 extending along a first direction X is provided on the bottom surface of the first mounting plate 1. Multiple placement mechanisms 5 are slidably connected to the first slide rail 2. The multiple placement mechanisms 5 are spaced apart along the first direction X. Each placement mechanism 5 includes a second mounting plate 51, a first driving member 52, a third mounting plate 54, a small material fixing assembly 57, and a lead wire straightening assembly 58.

[0035] The second mounting plate 51 is horizontally positioned and slidably connected to the first slide rail 2. The first driving member 52 is connected to the second mounting plate 51 and is used to drive the second mounting plate 51 to slide on the first slide rail 2, thereby allowing independent adjustment of the position of each placement mechanism 5 in the first direction X, so that each placement mechanism 5 corresponds to the position where EVA small materials need to be placed. The third mounting plate 54 is vertically positioned and fixedly connected to one end of the second mounting plate 51 along the second direction Y. The third mounting plate 54 has a second slide rail 55 and a third slide rail 56 on opposite sides in the second direction Y, respectively. Both the second slide rail 55 and the third slide rail 56 extend along the vertical direction Z. The second slide rail 55 is located on the side away from the second mounting plate 51, and the third slide rail 56 is located on the side closer to the second mounting plate 51. The small material fixing assembly 57 is slidably connected to the second slide rail 55 and is used to grip and place EVA small materials. The lead wire correction component 58 is slidably connected to the third slide rail 56 and is used to correct the lead wires on the photovoltaic module to the correct position, so that the holes on the EVA material can be aligned with the lead wires and placed down.

[0036] It should be noted that the first direction X, the second direction Y, and the vertical direction Z are mutually perpendicular, and the first direction X and the second direction Y are two mutually perpendicular directions in the horizontal plane.

[0037] The EVA small material placement device provided in this embodiment allows multiple placement mechanisms 5 to be slidably connected to the first slide rail 2 of the first mounting plate 1, thereby enabling the simultaneous placement of multiple EVA small materials and improving placement efficiency. Furthermore, each placement mechanism 5 is equipped with a small material fixing component 57 and a lead wire correction component 58. Before placing the EVA small material using the small material fixing component 57, the lead wire correction component 58 can be used to correct the lead wires on the photovoltaic module to the correct position, thereby improving placement accuracy.

[0038] In this embodiment, such as Figure 3 As shown, the small material fixing assembly 57 includes a second driving member 571 and a fourth mounting plate 572. The fourth mounting plate 572 is vertically arranged and slidably connected to the second slide rail 55. The second driving member 571 is connected to the fourth mounting plate 572 and is used to drive the fourth mounting plate 572 to slide on the second slide rail 55, thereby causing the EVA small material to move in the vertical Z direction.

[0039] In one embodiment, the small material fixing component 57 includes a suction cup 573 for adsorbing the upper surface of the EVA small material. After the small material is placed in position, the suction cup 573 stops adsorbing and separates from the small material. The suction cup 573 is fixedly installed on the side of the fourth mounting plate 572 away from the third mounting plate 54. This embodiment corresponds to the case where only one layer of EVA small material needs to be placed and the hole is a single circular hole.

[0040] In another embodiment, the small material fixing assembly 57 includes two gripper assemblies 574 for gripping the EVA small material on opposite sides in the first direction X. After the small material passes through the lead wire, the gripper assemblies 574 can release the small material. The two gripper assemblies 574 are mounted on the side of the fourth mounting plate 572 away from the third mounting plate 54. The gripper assembly 574 includes a fixed gripper 5741 and a movable gripper 5742. The movable gripper 5742 is connected to a third driving member 5743 for driving the movable gripper 5742 to move in the vertical direction Z to move closer to or away from the fixed gripper 5741. This embodiment corresponds to the case where two layers of EVA small material need to be placed.

[0041] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the small material fixing component 57 includes a suction cup 573 and two gripper assemblies 574, so the placement mechanism 5 can be used to place one layer of small material or two layers of small material, thus having a wider range of applications. The two gripper assemblies 574 are respectively located on both sides of the suction cup 573 along the first direction X, that is, the two gripper assemblies 574 are symmetrically arranged on both sides of the suction cup 573 in the first direction X.

[0042] Preferably, a visual positioning camera is fixedly installed above the placement mechanism 5 to detect whether the lead wire is aligned in place, which is suitable for cases where the holes of EVA small materials are double I-shaped holes.

[0043] like Figure 3 and Figure 5 As shown, the lead wire correction assembly 58 includes a fourth driving member 581, a fifth mounting plate 582, and a correction unit 585. The fifth mounting plate 582 is vertically arranged and slidably connected to the third slide rail 56. The fourth driving member 581 is connected to the fifth mounting plate 582 and is used to drive the fifth mounting plate 582 to slide on the third slide rail 56, thereby causing the correction unit 585 to move in the vertical direction Z. The correction unit 585 is mounted on the bottom of the fifth mounting plate 582 and faces the small material fixing assembly 57.

[0044] Specifically, the bottom of the fifth mounting plate 582 is provided with a fourth slide rail 583 extending along the second direction Y. The lead wire correction assembly 58 also includes a connecting block 584 slidably connected to the fourth slide rail 583. The correction unit 585 is connected to the side of the connecting block 584 facing the small material fixing assembly 57, so that the correction unit 585 can move along the second direction Y to approach or move away from the lead wire. When the hole of the EVA small material is a round hole, the correction unit 585 moves away from the lead wire in the second direction Y and its function is not needed; when the hole of the EVA small material is a double I-shaped hole, the correction unit 585 moves closer to the lead wire in the second direction Y and its correction function is needed to assist in the placement of the small material.

[0045] In this embodiment, in order to ensure the stability of the structure, a support plate 59 is fixedly provided between the second mounting plate 51 and the third mounting plate 54.

[0046] like Figure 2 As shown, there are two first slide rails 2, which are spaced apart in the second direction Y. The second mounting plate 51 is connected to the two first slide rails 2 via two sliders 4. The first driving member 52 is located between the two first slide rails 2.

[0047] Specifically, the bottom surface of the first mounting plate 1 is provided with a rack 3 extending along the first direction X, and the output end of the first driving member 52 is connected to a gear 53 that meshes with the rack 3, thereby enabling the placement mechanism 5 to move on the first slide rail 2.

[0048] It should be noted that in the description of this specification, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this specification, unless otherwise stated, "a plurality of" means two or more.

[0049] Any numerical values ​​cited herein include all values ​​ranging from a lower limit to an upper limit, increasing by one unit, with at least two units between any lower and any higher value. For example, if the quantity of a component or the value of a process variable (e.g., temperature, pressure, time, etc.) is described as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in this specification. For values ​​less than 1, a unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1, etc. These are merely examples intended for explicit expression, and it can be assumed that all possible combinations of values ​​listed between the minimum and maximum values ​​are explicitly described in this specification in a similar manner.

[0050] Unless otherwise stated, all ranges include the endpoints and all numbers between them. The terms "approximately" or "about" used with ranges apply to both endpoints of the range. Thus, "approximately 20 to 30" is intended to cover "approximately 20 to approximately 30," including at least the specified endpoints.

[0051] All articles and references disclosed herein, including patent applications and publications, are incorporated herein by reference for various purposes. The term “substantially constitutes…” used to describe a combination should include the identified elements, components, parts, or steps, as well as other elements, components, parts, or steps that do not substantially affect the essential novelty of the combination. The use of the terms “comprising” or “including” to describe combinations of elements, components, parts, or steps herein also contemplates embodiments substantially constituted by such elements, components, parts, or steps. The use of the term “may” herein is intended to indicate that any described attribute included by “may” is optional.

[0052] Multiple elements, components, parts, or steps can be provided by a single integrated element, component, part, or step. Alternatively, a single integrated element, component, part, or step can be divided into multiple separate elements, components, parts, or steps. The use of "a" or "an" to describe an element, component, part, or step does not imply the exclusion of other elements, components, parts, or steps.

[0053] It should be understood that the above description is for illustrative purposes and not for limitation. Many embodiments and applications beyond the provided examples will be apparent to those skilled in the art upon reading the above description. Therefore, the scope of this teaching should not be determined by reference to the above description, but rather by reference to the appended claims and the full scope of their equivalents. For purposes of completeness, all articles and references, including patent applications and publications, are incorporated herein by reference. The omission of any aspect of the subject matter disclosed herein in the preceding claims is not intended as a waiver of that subject matter, nor should it be construed as an indication that the inventors have not considered that subject matter as part of the disclosed utility model subject matter.
