After the left XY loading module or the right XY loading module places the photovoltaic module frame on the wafer carrier plate, it is detected by the wafer detection photoelectric sensor. The Z-axis mover causes the wafer carrier plate to move downward by a distance equal to the thickness of the photovoltaic module frame, ensuring that the discharging height of the photovoltaic module frame by the loading module is consistent each time. This simplifies the structure of the loading module, enables counting, precisely controls the number of magazines loaded, and gives an alarm in a timely manner when the magazine is full, facilitating the timely replacement of the magazine.

[0027] 2. Taking the right XY loading module as an example in the present invention, when the loading module adsorbs and transports the photovoltaic module frame on the receiving conveyor belt to the storage unit, XY movement is achieved through the first X-axis module and the first Y-axis module, enabling the right XY loading module to serve two groups of receiving conveyor belts and storage units. By using the time when the wafer carrier plate descends after the photovoltaic module frame is discharged and detected by the wafer detection photoelectric sensor in a single storage unit, the right XY loading module transfers the photovoltaic module frame to the other group of receiving conveyor belts and storage unit, realizing alternate discharging and improving the loading efficiency.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0040] 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 present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0041] Embodiment 1

[0042] Please refer to Figures 1-8 , the present invention provides a technical solution: a clip - type alternating material receiving device for a photovoltaic module frame after tin storage, including:

[0043] Frame 1;

[0044] A conveying module, which includes a plurality of receiving conveyor belts 2 arranged in parallel, and one end of the receiving conveyor belt 2 extends to the discharge port of the soldering furnace;

[0045] A storage module, which includes a plurality of storage units 3 arranged in parallel, and one storage unit 3 corresponds to one receiving conveyor belt 2 in position;

[0046] A material receiving module, which is used to adsorb and transport the photovoltaic module frame 9 on the receiving conveyor belt 2 to the storage unit 3. The material receiving module includes a left XY material receiving module 4 and a right XY material receiving module 5 symmetrically arranged on the left and right sides of the frame 1;

[0047] Among them, the storage unit 3 includes a Z-axis mover 31, a magazine seat 32, a wafer carrier 33 and a magazine 34. The magazine seat 32 is arranged on the upper side of the Z-axis mover 31, the magazine 34 is placed in the magazine seat 32, one side of the magazine seat 32 is provided with an opening for the magazine 34 to move in or out, a wafer detection photoelectric sensor 321 is arranged at the top opening of the magazine seat 32, a lifting slider 311 is arranged on the Z-axis mover 31, and the wafer carrier 33 is fixedly installed on the lifting slider 311. The wafer carrier 33 passes through the magazine seat 32 and the magazine 34.

[0048] Guide grooves 323 are arranged on a pair of opposite side walls of the magazine seat 32, and limiting sliders corresponding to the guide grooves 323 in position are arranged on the surface of the magazine 34. The limiting sliders are slidably connected in the guide grooves 323. When the magazine 34 is placed in the magazine seat 32, the position of the magazine 34 in the vertical direction is locked through the sliding connection between the limiting sliders and the guide grooves 323, preventing the position of the magazine 34 from shifting, so that the wafers can be placed smoothly.

[0049] A magazine detection switch 322 is also arranged on the side wall of the magazine seat 32. The magazine detection switch 322 is used to detect whether there is a magazine 34 in the magazine seat 32, and prompt the staff to replenish the magazine 34 in time, so as to avoid the material receiving module directly placing the wafers (i.e., the photovoltaic module frame 9) in the magazine seat 32.

[0050] A shield 11 is arranged on the frame 1, and the position of the shield corresponds to the receiving conveyor belt 2. The shield 11 shields the receiving conveyor belt 2 at the material receiving position to protect the adsorption process of the photovoltaic module frame 9 from being disturbed.

[0051] Working principle: The photovoltaic module frame 9 after storing tin output from the discharging port of the soldering furnace enters the receiving conveyor belt 2 and continues to be conveyed, and is placed in the storage unit 3 by the left XY receiving module 4 or the right XY receiving module 5. During the process of placing the photovoltaic module frame 9 in the magazine 34 within the storage unit 3, in the initial state, the wafer support plate 33 moves to a top surface height consistent with the top surface height of the magazine seat 32. After the left XY receiving module 4 or the right XY receiving module 5 places the photovoltaic module frame 9 on the wafer support plate 33, it is detected by the wafer detection optoelectronic device 321, and the Z-axis mover 31 causes the wafer support plate 33 to move downward by a distance equal to the thickness of the photovoltaic module frame 9, so that the discharging height of the photovoltaic module frame 9 is consistent each time by the receiving module, simplifies the structure of the receiving module, and can achieve counting, accurately control the receiving quantity of the magazine 34, and give an alarm in time when the magazine 34 is full, and replace the magazine 34 in time.

[0052] Embodiment 2

[0053] On the basis of the above embodiment, the following technical solutions for improvement are further made in this embodiment: The receiving conveyor belt 2 includes a conveying frame 21, a conveyor belt unit 22, a position detection optical fiber 23, a material blocking cylinder 24, a receiving position detection optical fiber 25 and a baffle 26. A material blocking piece 211 is provided at one end of the conveying frame 21. Two parallel conveyor belt units 22 are provided on the conveying frame 21. The photovoltaic module frame 9 is placed on the conveyor belt of the conveyor belt unit 22. The position detection optical fiber 23, the material blocking cylinder 24 and the receiving position detection optical fiber 25 are arranged in sequence along a straight line between the two conveyor belt units 22. Symmetrically arranged baffles 26 are provided on both sides of the conveying frame 21, and a guiding inclined surface 261 is provided at the end of the baffle 26.

[0054] The photovoltaic module frame 9 output from the discharging port of the soldering furnace is introduced into the receiving conveyor belt 2 through the guiding inclined surface 261 of the baffle 26 to realize the alignment of the photovoltaic module frame 9, and then is conveyed forward through the conveyor belt unit 22. When the photovoltaic module frame 9 is blocked by the material blocking piece 211 and detected by the receiving position detection optical fiber 25, the piston of the material blocking cylinder 24 extends upward to block the subsequent photovoltaic module frame 9 from continuing to be conveyed, so that the photovoltaic module frame 9 at the receiving position can be taken away by the receiving module without being affected.

[0055] The position detection optical fiber 23 is used to detect whether there is a lack of material on the receiving conveyor belt 2.

[0056] Embodiment 3

[0057] On the basis of the above embodiment, the following technical solutions for improvement are further made in this embodiment: A first waist-shaped hole 262 is provided on the baffle 26.

[0058] The first waist-shaped hole 262 enables the adjustable distance between the side edges 26 on both sides of the conveying rack 21, flexibly adjusts the distance according to the width of the photovoltaic module frame 9, improves the positioning effect on the photovoltaic module frame 9, and facilitates subsequent adsorption and picking.

[0059] Embodiment 4

[0060] Based on the above embodiments, the following further improved technical solutions are made in this embodiment: The right XY material receiving module 5 includes a first X-axis module 51, a first Y-axis module 52, a first lifting cylinder 53, a first adsorption rack 54, and a first suction nozzle 55. The first Y-axis module 52 is slidably connected to the first X-axis module 51, the first lifting cylinder 53 is slidably connected to the first Y-axis module 52, the first adsorption rack 54 is fixedly installed on the piston rod of the first lifting cylinder 53, and the first suction nozzle 55 is fixedly installed on the first adsorption rack 54. The left XY material receiving module 4 has the same structure and working principle as the right XY material receiving module 5.

[0061] Taking the right XY material receiving module 5 as an example, when the material receiving module adsorbs and transports the photovoltaic module frame 9 on the material receiving conveyor belt 2 to the storage unit 3, XY movement is achieved through the first X-axis module 51 and the first Y-axis module 52, so that the right XY material receiving module 5 can take into account two groups of material receiving conveyor belts 2 and storage units 3. Using the time when the material piece detection photoelectric 321 in a single storage unit 3 detects the lowering of the material piece support plate 33 after the photovoltaic module frame 9 is placed, the right XY material receiving module 5 transfers the photovoltaic module frame 9 to the other group of material receiving conveyor belts 2 and storage units 3 to achieve alternate feeding and improve the material receiving efficiency.

[0062] Embodiment 5

[0063] Based on the above embodiments, the following further improved technical solutions are made in this embodiment: The first suction nozzle 55 is fixedly installed on the mounting piece 551, and a second waist-shaped hole 552 is provided on the mounting piece 551. The locking bolt passes through the second waist-shaped hole 552 and is then fixedly installed on the first adsorption rack 54.

[0064] When the first suction nozzle 55 is installed on the first adsorption rack 54 through the mounting piece 551, the position can be flexibly adjusted by using the second waist-shaped hole 552 on the mounting piece 551 to achieve the adsorption of different specifications of material pieces.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
