[0002] For large-sized solar panels, when using suction cup assemblies to grip and load them, multiple suction cups can be set to reduce the suction force at a single point and avoid causing damage from excessive suction. However, when changing solar panel products of different sizes, new suction cup assemblies need to be replaced, which results in poor versatility and cumbersome replacement. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multi-size solar panel suction cup gripping mechanism that does not require replacement of the suction cup assembly when changing solar panel products of different sizes.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a suction cup gripping mechanism for solar panels of various sizes, comprising a housing, a negative pressure suction cup, a suction cup base, a throttling connector, a sealing sleeve, a sealing ball, and a support plate; The housing has an air passage interface and an inner cavity. The top of the negative pressure suction cup is sealed and fixedly installed on the suction cup seat. Multiple suction cup seats are linearly distributed and screwed and sealed and fixedly installed on the housing. The air passage interface and suction cup seats are connected to the inner cavity. The throttling connector is sealed and fixedly installed on the suction cup seat. The support plate is screwed and fixedly installed on the bottom of the throttling connector. The sealing sleeve is sleeved and installed on the bolt. The sealing sleeve is clamped and fixed between the support plate and the throttling connector. The throttling connector has a first through hole. The sealing sleeve has a second through hole. The second through hole is coaxial with the first through hole. The diameter of the second through hole is 1.8-2.5 times the diameter of the first through hole. The sealing ball is located in the second through hole and placed on the support plate. The diameter of the sealing ball is 0.75-0.8 times the diameter of the second through hole. The support plate is provided with several third through holes connected to the second through hole. The diameter of the third through hole is 0.05-0.1 times the diameter of the first through hole. The spacing between the edges of adjacent negative pressure suction cups is set to 5-10mm.

[0005] Preferably, it also includes a carrier plate, which is fixedly installed on the housing, and a joint post is fixedly provided at the center of the carrier plate.

[0006] Preferably, it also includes a spring telescopic rod and a control module.

[0008] Preferably, the center of the top surface of the tray is set as a concave structure, the sealing ball is placed on the concave structure, and the third through hole is located inside the concave structure.

[0009] Compared with existing technologies, the advantages of this invention are: the small spacing between adjacent negative pressure suction cups on the suction cup gripping mechanism allows for the installation of a larger number of negative pressure suction cups, thereby reducing the suction force of a single negative pressure suction cup on the solar panel and preventing damage from excessive suction. Furthermore, the sealing ball can seal the first through hole of unused negative pressure suction cup assemblies, ensuring the airtightness of the inner cavity. When replacing solar panels of different sizes, there is no need to replace the suction cup assembly, demonstrating its strong versatility. Attached Figure Description

[0013] The present invention will now be described in detail with reference to specific embodiments: Figure 1 and Figure 2 The suction cup gripping mechanism for solar panels of various sizes shown includes a housing 1, a negative pressure suction cup 3, a suction cup base 5, a throttling connector 6, a sealing sleeve 7, a sealing ball 8, and a support plate 9. The housing 1 has an air passage interface 11 and an inner cavity 10. The top of the negative pressure suction cup 3 is sealed and fixedly installed on the suction cup seat 5. Multiple suction cup seats 5 are linearly distributed and screwed and sealed and fixedly installed on the housing 1. The air passage interface 11 and the suction cup seat 5 are both connected to the inner cavity 10. The throttling connector 6 is sealed and fixedly installed on the suction cup seat 5. The support plate 9 is screwed and fixedly installed on the bottom of the throttling connector 6 by bolts 72. The sealing sleeve 7 is sleeved and installed on the bolts 72. The sealing sleeve 7 is clamped and fixed between the support plate 9 and the throttling connector 6. The throttling connector 6 has a first through hole 61, and the sealing sleeve 7 has a second through hole 71. The second through hole 71 is connected to the first through hole. The first through hole 61 is coaxially arranged. The diameter of the second through hole 71 is 1.8-2.5 times the diameter of the first through hole 61. The sealing ball 8 is located inside the second through hole 71 and placed on the support plate 9. The diameter of the sealing ball 8 is 0.75-0.8 times the diameter of the second through hole 71. The support plate 9 is provided with several third through holes 91 that are connected to the second through hole 71. The diameter of the third through hole 91 is 0.05-0.1 times the diameter of the first through hole 61. The support plate 9 is fixedly installed with a sealing ring 92, which is slidably installed on the inner wall of the suction cup seat 5 to increase the airtightness between the support plate 9 and the inner wall of the suction cup seat 5.

[0014] The spacing between the edges of adjacent negative pressure suction cups 3 is set to 5-10mm to accommodate a larger number of negative pressure suction cup 3 components.

[0015] It also includes a carrier plate 2, which is fixedly installed on the housing 1. A connector post 21 is fixedly provided at the center of the carrier plate 2 so that the suction cup assembly can be connected and fixed to the automated robotic arm.

[0016] It also includes a spring telescopic rod 4 and a control module. The sleeve of the spring telescopic rod 4 is fixedly installed on the housing 1. A touch switch 41 is fixedly installed on the rod of the spring telescopic rod 4. The touch switch 41 is connected to the control module and the power supply module through a circuit. After the negative pressure suction cup 3 picks up the solar panel, the solar panel presses against the touch switch 41, causing it to generate an electrical signal, which is sent to the control module. The control module is connected to an audible alarm system to detect whether the negative pressure suction cup 3 has picked up the solar panel. When changing to solar panel products of different sizes, the negative pressure suction cup 3 around the touch switch 41 is always used to grab the solar panel to ensure that the success of the grabbing is monitored. Under normal circumstances, a pressure sensor is installed in the inner cavity 10 of the housing 1. The touch switch 41 can still play a monitoring role in the event of a pressure sensor failure.

[0017] The number of third through holes 91 is set to 13 to ensure the flow of negative pressure airflow and to give the negative pressure suction cup 3 sufficient suction force.

[0018] The top surface of the tray 9 is set with a concave structure at the center. The sealing ball 8 is placed on the concave structure. The third through holes 91 are all arranged in a ring inside the concave structure. In this way, the sealing ball 8 is located at the center of the concave structure. The airflow through the third through hole 91 can more easily blow the sealing ball 8 upward to block the first through hole 61.

[0019] The air interface 11 is connected to the negative pressure generating device through a pipeline and a solenoid valve. When the negative pressure generating device is started, the negative pressure suction cup 3 contacts the solar panel and picks it up. If the negative pressure suction cup 3 is not fully used, under the action of atmospheric pressure, the sealing ball 8 in the second through hole 71 is blown upward to seal the first through hole 61, ensuring the airtightness of the inner cavity 10 and preventing the negative pressure suction cup 3 that has been picked up from falling.
