[0043] Embodiment 1

[0044] Please refer to Figures 1-8 , the present invention provides a technical solution: a double-station turnover box receiving device for a photovoltaic module frame after melting tin in a soldering furnace, including:

[0045] Frame 1;

[0046] The conveyor belt group includes a plurality of receiving conveyor belts 2 arranged in parallel. One end of the receiving conveyor belt 2 extends to the discharge port of the soldering furnace, and the receiving conveyor belt 2 is used to convey the photovoltaic module frame 9;

[0047] The receiving module includes an X-axis double-slider linear module 3, a left YZ module 4, a right YZ module 5, and a receiving box 6. The X-axis double-slider linear module 3 is provided with a first slide and a second slide. The left YZ module 4 is fixedly installed on the first slide, the right YZ module 5 is fixedly installed on the second slide, and the receiving box 6 is arranged on the front side of the conveyor belt group;

[0048] The right YZ module 5 includes a Y-axis linear module 51, a Z-axis lead screw module 52, a lifting frame 53, a vacuum generator 54, and a suction nozzle 55. The Y-axis linear module 51 is fixedly installed on the second slide, the Z-axis lead screw module 52 is fixedly installed on the sliding seat of the Y-axis linear module 51, the lifting frame 53 is fixedly installed on the sliding seat of the Z-axis lead screw module 52, a plurality of suction nozzles 55 are arranged on the lifting frame 53, the vacuum generator 54 is fixedly installed on the lifting frame 53, and the suction nozzle 55 is connected to the vacuum generator 54 through an air pipe.

[0049] The left YZ module 4 and the right YZ module 5 have the same structure and working principle. Taking the right YZ module 5 as an example, the right YZ module 5 realizes the movement in the X-axis direction through the slide of the X-axis double-slider linear module 3, realizes the movement in the YZ direction of the lifting frame 53 through the Y-axis linear module 51 and the Z-axis lead screw module 52. The vacuum generator 54 is used to make the suction nozzle 55 generate negative pressure, so that after the suction nozzle 55 adsorbs the photovoltaic module frame 9 from the conveyor belt group, it can move in the XYZ directions and place the photovoltaic module frame 9 into the receiving box 6.

[0050] The blanking conveyor belt 2 includes a support frame 21, a conveyor belt unit 22, a first detection optical fiber 23, a second detection optical fiber 24, and a blocking cylinder 25.

The first detection optical fiber 23 and the second detection optical fiber 24 are arranged in sequence along a straight line between the two conveyor belt units. The blocking cylinder 25 is arranged between the first detection optical fiber 23 and the second detection optical fiber 24.

[0051] When the photovoltaic module frame 9 output by the soldering furnace enters the blanking conveyor belt 2, it is driven forward by the belt of the conveyor belt unit 22. After the photovoltaic module frame 9 is conveyed past the first detection optical fiber 23, it is blocked by the baffle 211 at the end of the support frame 21 and detected by the second detection optical fiber 24, determining that there is a photovoltaic module frame 9 at the loading position of the blanking conveyor belt 2. At this time, the piston rod of the blocking cylinder 25 drives the block to move upward, blocking the photovoltaic module frame 9 on the conveyor belt unit 22 from continuing to be conveyed forward, so that the photovoltaic module frame 9 at the loading position can be taken away by the material receiving module without being affected.

[0052] Symmetrically arranged shielding covers 12 are provided on both sides of the frame 1. It effectively protects and hides the adsorption and transfer process of the photovoltaic module frame 9, improving the safety of material receiving.

[0053] Working principle: When the photovoltaic module frame is output from the soldering furnace, it is continuously conveyed by the conveyor belt group and is sucked and placed in the material receiving box 6 by the left YZ module 4 and the right YZ module 5 at the material receiving module. The left YZ module 4 and the right YZ module 5 independently realize the movement in the X-axis direction through the two sliders of the X-axis double-slider linear module 3. The left YZ module 4 and the right YZ module 5 alternately place the photovoltaic module frame 9 on the conveyor belt group into a single material receiving box 6. After a material receiving box 6 is filled, the full material receiving box 6 is replaced, and at the same time, the photovoltaic module frame 9 is placed in another material receiving box 6, realizing the two-station blanking of the photovoltaic module frame and effectively improving the material receiving efficiency.

A bending edge 621 is arranged at the top of the edge baffle 62, realizing the separation and positioning of the two material receiving boxes 6, and facilitating the accurate feeding of the left YZ module 4 and the right YZ module 5.

[0059] A bevel 622 is arranged at the end of the edge baffle 62 to prevent the edge baffle 62 from affecting the handling of the material receiving box 6 and facilitate the replacement of the material receiving box 6.

[0060] A partition plate 63 is arranged on the intermediate baffle 61. The cross-section of the partition plate 63 is in a "T" shape. The top plate of the partition plate 63 extends to the upper side of the material receiving box 6. The partition plate 63 is detachably installed on the intermediate baffle 61 by bolt connection. On the one hand, the top plate of the partition plate 63 cooperates with the bending edge 621 of the edge baffle 62 to position the material receiving box 6.
