[0036] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0037] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0038] According to an embodiment of the utility model, on the one hand, a feeder 100 is provided, comprising a buffer streamline 1, a feeding mechanism 2 and a pick-and-place mechanism 3. The buffer streamline 1 is used to convey a pile of auxiliary materials; the feeding end of the feeding mechanism 2 is docked with the discharging end of the buffer streamline 1, and the feeding mechanism 2 is used to output a single sheet of auxiliary materials 300; the pick-and-place mechanism 3 is docked with the discharging end of the feeding mechanism 2, and the pick-and-place mechanism 3 is suitable for picking and placing a single sheet of auxiliary materials 300.

[0039] The feeder 100 provided in this embodiment can be used to cache and convey the auxiliary material pile by setting the buffer streamline 1, and the auxiliary material 300 is loaded from the buffer streamline 1. By setting the feeding mechanism 2, the feeding end of the feeding mechanism 2 and the discharging end of the buffer streamline 1 are docked, so that the auxiliary material 300 on the buffer streamline 1 can enter the feeding mechanism 2, and the feeding mechanism 2 can output the auxiliary material 300 in a single sheet, avoiding the loading of multiple auxiliary materials 300. By setting the picking and placing mechanism 3, the picking and placing mechanism 3 can grab a single auxiliary material 300 and place the auxiliary material 300 on the flow conveying line 200 of the auxiliary material 300, so as to realize the single loading of the auxiliary material 300. Through the coordination relationship among the buffer streamline 1, the feeding mechanism 2 and the picking and placing mechanism 3, the single loading of the auxiliary material 300 can be realized, avoiding the joint loading of multiple auxiliary materials 300, and ensuring a good picking and placing effect.

[0040] In addition, by setting a cache streamline 1 and changing the length and running speed of the cache streamline 1, the cache capacity when the auxiliary material 300 is loaded can be increased, so that the cache time is not less than 1.5 hours.

[0041] Specifically, the buffer streamline 1 includes a conveyor belt 11 , which provides conveying power toward the material dispensing mechanism 2 and can transport the auxiliary material pile to the material dispensing mechanism 2 .

[0042] The buffer streamline 1 also includes a guide mechanism, which includes two upright guide plates, which are respectively arranged on both sides of the conveyor belt 11. By setting the guide mechanism, the auxiliary material 300 on the conveyor belt 11 can be guided to ensure the neat movement of the auxiliary material 300.

[0043] Specifically, the auxiliary material 300 includes sulfur-free paper, foam, and cardboard. The auxiliary material 300 is placed piece by piece or stacked one by one in the buffer flow line 1. The buffer flow line 1 can drive the auxiliary material pile to move toward the material delivery mechanism 2.

[0044] In one embodiment, the material delivery mechanism 2 includes a material trough connected to the discharge end of the buffer streamline 1 and a material blocking assembly 22 arranged on the discharge side of the material trough. The material blocking assembly 22 is suitable for blocking the auxiliary material pile. A discharge gap is left between the material blocking assembly 22 and the bottom of the material trough. The discharge gap is suitable for passing a single auxiliary material 300 located at the bottom of the auxiliary material pile.

[0045] By setting a material trough, the material trough is butted with the discharge end of the buffer streamline 1, and the auxiliary material pile flowing out of the buffer streamline 1 enters the material trough. Since the material has not been discharged yet, the auxiliary material pile in the buffer streamline 1 directly enters the material trough under the conveying power of the buffer streamline 1. Therefore, the auxiliary material 300 in the material trough is still a pile of stacked sheets. By setting the blocking component 22, the blocking component 22 can block the auxiliary material pile, and a discharge gap is left between the blocking component 22 and the bottom of the material trough. Therefore, at least part of the single auxiliary material 300 located at the bottom of the material pile can enter the discharge gap, which is convenient for subsequent single discharge.

[0046] In one embodiment, the material feeding mechanism 2 also includes a conveying component 21 located downstream of the material blocking component 22 along the conveying direction, and the conveying component 21 includes a supporting roller group and a conveying roller group. The conveying roller group is arranged above the supporting roller group. A conveying gap for a single sheet of auxiliary material 300 to pass through is provided between the conveying roller group and the supporting roller group. A feeding roller is provided between the conveying gap and the discharging gap. The feeding roller is used to convey the single sheet of auxiliary material 300 from the discharging gap to the conveying gap.

[0047] The feeding mechanism 2 is provided with a conveying assembly 21, which can drive the single auxiliary material 300 in the discharge gap forward by friction, so that the blocking assembly 22 cooperates with the conveying assembly 21 to ensure that only one auxiliary material 300 is discharged each time, thereby realizing the feeding of a single auxiliary material 300. Since the discharge gap and the conveying gap are connected, the feeding roller located between the discharge gap and the conveying gap can bring the auxiliary material 300 at the bottom of the auxiliary material pile from the discharge gap to the conveying gap, and then the conveying roller group drives the auxiliary material 300 to flow out of the conveying gap, thereby realizing the feeding of a single auxiliary material 300.

[0048] Specifically, the transmission component 21 has two roller groups spaced apart above and below, which are a supporting roller group and a conveying roller group located above the supporting roller group. Since a conveying gap is provided between the supporting roller group and the conveying roller group, and the conveying gap and the discharge gap are butted against each other, and are connected via a feeding roller located between the conveying gap and the discharge gap, the surface of the feeding roller contacts the front end surface of the auxiliary material 300 located in the discharge gap, and the feeding roller rolls, thereby moving the auxiliary material 300 from the discharge gap to the transmission gap, and the surface of the auxiliary material 300 entering the transmission gap contacts the surface of the conveying roller group, thereby, the rotation of the conveying roller group can drive the auxiliary material 300 to continue to move forward, and the auxiliary material 300 continues to move forward driven by the conveying roller group until it leaves the transmission gap, thereby realizing the delivery of a single sheet of auxiliary material 300.

[0049] It should be noted that the material dispensing mechanism 2 in the accompanying drawings is a simplified schematic diagram with some components omitted. The structure of the material dispensing mechanism 2 is the same as the working principle of the card dispensing machine. Those skilled in the art are able to know the specific structure of the material dispensing mechanism 2, and the specific structure of the material dispensing mechanism 2 will not be introduced here.

[0050] In one embodiment, the material dispensing mechanism 2 further comprises a material receiving box 23 disposed at the discharging end of the material dispensing mechanism 2 , and the material receiving box 23 is used to receive the single sheet of auxiliary material 300 discharged from the conveying gap.

[0051] By arranging a receiving box 23 at the discharge end of the material discharging mechanism 2, the receiving box 23 can be used to receive the bottom sheet of auxiliary material 300 emitted from the conveying gap, that is, the auxiliary material 300 coming out of the conveying gap directly enters the receiving box 23, and the contour of the inner cavity of the receiving box 23 is adapted to the outer contour of the auxiliary material 300. After the auxiliary material 300 falls into the receiving box 23, the receiving box 23 can position the auxiliary material 300 to ensure that the auxiliary material 300 emitted each time is positioned at the same position, which is convenient for the subsequent material retrieving machine to retrieve the material.

[0052] In one embodiment, the picking and placing mechanism 3 includes a moving component 31 arranged along the conveying direction and an adsorption component 32 arranged on the moving component 31. The moving component 31 is suitable for driving the adsorption component 32 to move along the conveying direction, and the adsorption component 32 is suitable for absorbing or releasing the auxiliary material 300 issued by the material issuing mechanism 2.

[0053] The pick-and-place mechanism 3 can drive the adsorption component 32 to move by setting a moving component 31, and the adsorption component 32 can adsorb the auxiliary material 300 issued by the material issuing mechanism 2. After the adsorption component 32 adsorbs the auxiliary material 300, it can move along the conveying direction through the moving component 31 and release the auxiliary material 300 to a designated position. In one embodiment of the photovoltaic cell production system 1000, a flow conveyor line 200 is set below the adsorption component 32. After the adsorption component 32 adsorbs the auxiliary material 300 from the receiving box 23, it transfers and releases the auxiliary material 300 onto the flow conveyor line 200 under the drive of the moving module, so that the auxiliary material 300 follows the flow conveyor line 200 to the next station.

[0054] Specifically, the adsorption component 32 includes a vacuum suction cup, and the auxiliary material 300 is adsorbed by the vacuum suction cup to achieve stable placement.

[0055] In one embodiment, the moving assembly 31 includes a guide rail arranged along the conveying direction, a sliding seat slidably connected to the guide rail, and a driving mechanism for driving the sliding seat to move, and the adsorption assembly 32 is arranged on the sliding seat.

[0056] By providing a guide rail and a sliding seat slidably connected to the guide rail, and the adsorption assembly 32 is arranged on the sliding seat, the driving mechanism is activated to drive the sliding seat to slide on the guide rail, so that the adsorption assembly 32 slides on the guide rail with the sliding seat. Specifically, the driving mechanism includes a cylinder.

[0057] In one embodiment, the pick-and-place mechanism 3 further includes a rotating assembly 33, which includes a turntable 331 rotatably connected to the moving assembly 31, and the adsorption assembly 32 is disposed on the turntable 331, which is suitable for driving the adsorption assembly 32 to rotate to a set angle.

[0058] The pick-and-place mechanism 3 is provided with a rotating assembly 33, and the rotating assembly 33 is provided with a turntable 331, and the adsorption assembly 32 is provided on the turntable 331, so that the rotation of the turntable 331 can drive the adsorption assembly 32 to rotate, thereby driving the rotation of the auxiliary material 300 adsorbed by the adsorption assembly 32. By setting the rotation angle of the turntable 331, the rotation angle of the auxiliary material 300 can be controlled to achieve the angle adjustment when the auxiliary material 300 is placed. In one embodiment of the photovoltaic cell production system 1000, the conveying direction of the flow conveyor line 200 below the adsorption assembly 32 is perpendicular to the discharge direction of the auxiliary material 300 in the feeder 100, so the auxiliary material 300 adsorbed by the adsorption assembly 32 needs to be rotated 90 degrees, so the turntable 331 can drive the adsorption assembly 32 to rotate back and forth 90 degrees. Of course, the rotation angle is not limited to this, and can be determined according to actual needs.

[0059] In one embodiment, the loader 100 is provided with two working layers spaced apart from each other, each working layer is provided with a cache flow line 1, a material delivery mechanism 2 and a pick-and-place mechanism 3, and the cache flow line 1, the material delivery mechanism 2 and the pick-and-place mechanism 3 in the same working layer are connected in sequence.

[0060] By arranging two cache streamlines 1, material delivery mechanisms 2 and pick-and-place mechanisms 3 at intervals in the upper and lower parts, and connecting the cache streamlines 1, material delivery mechanisms 2 and pick-and-place mechanisms 3 located in the same working layer in sequence, a loader 100 can realize simultaneous loading of the upper and lower layers, which can double the efficiency of loading the auxiliary materials 300.

[0061] The feeder 100 provided in this embodiment has a modular splicing design for the feeding, dispensing and discharging of the auxiliary material 300 through the buffer streamline 1 feeding, the dispensing mechanism 2 dispensing a single sheet of material, and the pick-and-place mechanism 3 for stable picking and placing, so as to facilitate the functional selection of customers. Customers can customize the material buffering time to meet the production needs of different customers. The feeder 100 has a simple overall structure, reliable functions, high expandability and strong compatibility.

[0062] According to an embodiment of the utility model, on the other hand, a photovoltaic cell production system 1000 is also provided, including a conveyor line 200 and a loader 100 of any one of the above technical solutions; the conveyor line 200 is arranged below the pick-up and placement mechanism 3 of the loader 100, and the pick-up and placement mechanism 3 is suitable for placing a single sheet of auxiliary material 300 on the conveyor line 200.

[0063] Since the photovoltaic cell production system 1000 provided in this embodiment includes the above-mentioned material loader 100, the auxiliary materials 300 are buffered, sent out individually, and stably picked up and put away as required on site through the buffer streamline 1, the material delivery mechanism 2, and the pick-and-place mechanism 3. Since the flow conveyor line 200 of the photovoltaic cell production system 1000 is located below the pick-and-place mechanism 3, the auxiliary materials 300 grabbed by the pick-and-place mechanism 3 are directly placed on the flow conveyor line 200.

[0064] In addition, because the photovoltaic cell production system 1000 includes the loader 100 and has all the beneficial effects of the loader 100, they are not described in detail here.

[0065] In one embodiment, two conveyor lines 200 are arranged at intervals in the upper and lower parts, and the two conveyor lines 200 are respectively arranged below the pick-and-place mechanisms 3 in the two working layers.

[0066] In one embodiment, the buffer flow line 1, the material delivery mechanism 2 and the pick-and-place mechanism 3 are all provided in two layers, and accordingly, the flow conveyor line 200 is also provided in two layers, so that the production efficiency of the photovoltaic cells can be improved.

[0067] In one embodiment, a plurality of flow trays 2001 are arranged on the assembly line, and the pick-and-place mechanism 3 places the sucked auxiliary materials 300 in the flow trays 2001 .

[0068] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
