Description

Technical Field

[0001] The present invention relates to the technical field of battery packaging, and in particular to a photovoltaic battery packaging device. Background Art

[0002] Individual solar cells have very poor mechanical strength. Silicon wafers are only 200μm thick, making them thin and fragile. Since cells operate outdoors, they can be damaged by wind, rain, sandstorms, hail, and other natural weather conditions. Therefore, encapsulation is a critical step in solar photovoltaic cell production. The front of the panels must be made of tempered glass for both strength and light transmittance. A solar photovoltaic cell generally consists of a glass cover, a silicon solar cell, and a cassette-like bottom plate. The encapsulation steps are: first, place the silicon solar cell into the inner cavity of the cassette-like bottom plate, then place the glass cover on the top surface of the cassette-like bottom plate, and finally, seal with glue.

[0003] During the solar photovoltaic cell packaging process, various components need to be transported. Since the glass cover plate is relatively thin, in order to avoid damaging the edge area of ​​the glass cover plate, most of the time, a negative pressure suction cup is used to adsorb and clamp the glass cover plate. However, the negative pressure suction cup lacks a centering positioning function. The sizes of the various components are different, especially the box-type lower bottom plate has the largest size. When the glass cover plate is placed on the box-type lower bottom plate, it is necessary to ensure that the glass cover plate is just above the box-type lower bottom plate. At this time, manual fine-tuning of the position of the glass cover plate is required, which affects production efficiency. Based on this, the present invention proposes a photovoltaic cell packaging device. Summary of the Invention

[0015] Preferably, the positioning mechanism includes a first electric cylinder, the lower end of the first electric cylinder is fixedly connected to the upper end of the fixed plate, and the movable end of the first electric cylinder is installed with a clamping plate.

[0016] Preferably, a stepped surface is provided on one end of the clamping plate close to the fixing plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention realizes the clamping and centering of photovoltaic cell packaging components by setting up a clamping mechanism. When grabbing a component, the second electric cylinder first drives the negative pressure suction cup to descend and contact the component located on the loading station, and the component is adsorbed by the negative pressure suction cup. Then, the second electric cylinder drives the component to move between the four clamping plates, and the four first electric cylinders are started at the same time, so that the four clamping plates approach the component synchronously. When the component is about to approach the clamping plate, the negative pressure suction cup stops sucking air, and the clamping plate supports the component through the stepped surface. As the clamping plate contacts the component, the component is centered, and then the negative pressure suction cup starts sucking air again, generating negative pressure to adsorb the component. The centering of the component is ensured throughout the whole process.

[0021] (2) When stacking glass cover plates of smaller size, the position of the movable plate is first adjusted upward by the second electric cylinder so that the glass cover plate is located on the upper side of the step surface. When the clamping plate is driven by the conveying mechanism to move in the vertical downward direction, the clamping plate is just located on the outer side of the box-type lower base plate, and the upper wall of the step surface is just on the upper end edge of the box-type lower base plate, which facilitates the glass cover plate to directly enter the inner cavity of the box-type lower base plate, thereby improving the assembly accuracy and production efficiency.

[0022] (3) By setting up a placement mechanism to adjust the height of the upper end surface of the parts, when assembling solar photovoltaic cells of different thicknesses, the distance between the upper end surface of the parts of different thicknesses and the conveying mechanism can be made consistent, that is, the movement stroke of the conveying mechanism is ensured to be consistent, thereby improving the applicability of the device.

[0023] (4) A transport mechanism is provided to transport the parts from the transport mechanism to the placement mechanism. During the transport process, the parts are first raised in the plumb direction to prevent them from colliding with other objects during transportation, then moved horizontally to the top of the placement mechanism, and finally moved downward in the plumb direction to the top of the placement mechanism.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1-10 This embodiment proposes a photovoltaic cell packaging device, including a mounting frame 1 mounted above a transport mechanism 4, a conveying mechanism 2 arranged on the mounting frame 1, a clamping mechanism 3 installed on the conveying mechanism 2, and a placement mechanism 5 arranged below the mounting frame 1. The placement mechanism 5 and the transport mechanism 4 are symmetrically distributed with the conveying mechanism 2 as the center.

[0042] The transport mechanism 4 is used to transport the photovoltaic cell packaging components to the loading station. In this embodiment, the transport mechanism 4 adopts a belt conveyor in the prior art.

[0043] The transport mechanism 2 and the clamping mechanism 3 cooperate to grab the photovoltaic cell packaging components located on the loading station and transfer the photovoltaic cell packaging components to the placement mechanism 5 .

[0044] Specifically, the transport mechanism 2 includes a mounting plate 21, the mounting plate 21 is fixedly connected to the mounting frame 1 and is located in front of the cross plate 11, the front end of the mounting plate 21 is provided with a second U-shaped groove 22 that runs through the front and back, the two ends of the second U-shaped groove 22 are respectively located directly above the transport mechanism 4 and the placement mechanism 5, the second U-shaped groove 22 matches the first U-shaped groove 12, the middle part of the front end of the mounting plate 21 is rotatably connected to the driving rod 28, the front end of the driving rod 28 is provided with a driving groove 281 that runs through the front and back, and the length of the driving groove 281 satisfies the guide rod 27 in the first U In order to meet the need for rotation within the second U-shaped groove 12, the driving groove 281 is slidably connected to a guide rod 27, which is slidably connected to the second U-shaped groove 22. The front end of the guide rod 27 is rotatably connected to the vertical rod 26. A transverse guide rail 23 is installed at the lower front end of the mounting plate 21, and a transverse slider 24 is slidably connected to the transverse guide rail 23. The front end of the transverse slider 24 is installed with a vertical guide rail 25. The vertical guide rail 25 is slidably connected to the vertical rod 26. The vertical rod 26 and the transverse guide rail 23 are arranged perpendicular to each other, and the vertical rod 26 is parallel to the plumb bob. When transporting parts, the rotation of the driving rod 28 drives the guide rod 27 to move within the second U-shaped groove 22. In the horizontal direction, the guide rod 27 performs linear motion in the direction of the transverse guide rail 23, and in the vertical direction, the guide rod 27 performs lifting motion in the direction of the vertical guide rail 25.

[0045] Based on the above scheme, in this embodiment, the rotation of the driving rod 28 is driven by a motor 29. Specifically, the conveying mechanism 2 also includes a motor 29, the front end of the motor 29 is fixedly connected to the rear end of the horizontal plate 11, and the output end of the motor 29 passes through the horizontal plate 11 and the mounting plate 21 and is fixedly connected to the side of the driving rod 28 away from the guide rod 27.

[0046] In order to enable the guide rod 27 to move in the second U-shaped groove 22 to maintain a horizontal state, in this embodiment, the mounting frame 1 includes a transverse plate 11, a first U-shaped groove 12 is opened at the front end of the transverse plate 11, and the guide rod 27 is slidably connected to the first U-shaped groove 12.

[0047] Specifically, the clamping mechanism 3 includes a fixing plate 31, the upper end of which is fixedly connected to the lower end of the vertical rod 26. Positioning mechanisms 32 are provided on all four sides of the upper end of the fixing plate 31, and a suction mechanism 33 is provided at the lower end of the fixing plate 31. The suction mechanism 33 grasps the component, and the positioning mechanism 32 realizes the centering of the component.

[0048] Based on the above solution, the suction mechanism 33 includes a second electric cylinder 332, the upper end of which is fixedly connected to the lower end of the fixed plate 31. A movable plate 331 is mounted on the movable end of the second electric cylinder 332, and several negative pressure suction cups 333 are mounted on the lower end of the movable plate 331. When the clamping mechanism 3 moves to directly above the loading station, the movable end of the second electric cylinder 332 extends, driving the movable plate 331 downward. The movable plate 331 then drives the negative pressure suction cups 333 downward until they contact the component. The negative pressure suction cups 333 then draw air in, generating negative pressure to grasp the component.

[0049] The positioning mechanism 32 includes a first electric cylinder 321, the lower end of which is fixedly connected to the upper end of the fixed plate 31.

The clamping plate 322 moves when the movable end of the first electric cylinder 321 is extended or retracted, and the two clamping plates 322 on opposite sides move synchronously, achieving central positioning of the component in that direction.

[0050] Due to the different sizes of various components, especially the largest size of the cassette bottom plate, when placing the glass cover plate on the cassette bottom plate, it is necessary to ensure that the glass cover plate is just above the cassette bottom plate, that is, the cassette bottom plate needs to be positioned when placing the glass cover plate. In this embodiment, the clamping plate 322 is provided with a stepped surface 3221 at one end close to the fixed plate 31; when stacking smaller glass cover plates, the position of the movable plate 331 is first adjusted upward by the second electric cylinder 332 so that the glass cover plate is located on the upper side of the stepped surface 3221. When the clamping plate 322 is driven by the conveying mechanism 2 to move in a vertical downward direction, the clamping plate 322 is just located on the outside of the cassette bottom plate, and the upper wall of the stepped surface 3221 is just on the upper edge of the cassette bottom plate, so that the glass cover plate can directly enter the inner cavity of the cassette bottom plate.

[0051] On the basis of the above solution, in order to improve the stability of the clamping plate 322 during movement, in this embodiment, a limit rod 323 is installed on the end of the clamping plate 322 close to the fixed plate 31. The limit rod 323 movably passes through a fixed block 324, and the fixed block 324 is fixedly connected to the fixed plate 31. The guide limit function is activated by the limit rod 323.

[0052] The placement mechanism 5 is used to place photovoltaic cell packaging components, and the placement mechanism 5 moves along the plumb direction so that the height of the upper end surface of the photovoltaic cell packaging components remains unchanged.

[0053] When assembling solar photovoltaic cells of varying thicknesses, in order to ensure that the distance between the upper end surfaces of components of varying thicknesses and the transport mechanism 2 is consistent, that is, to ensure that the transport mechanism 2 has a consistent travel range, in this embodiment, the placement mechanism 5 includes a base plate 51, an oil cylinder 52 mounted on the upper end of the base plate 51, a tray 53 mounted on the upper end of the oil cylinder 52, and telescopic columns 531 mounted between the four corners of the lower end of the tray 53 and the base plate 51.
