[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] like Figure 1-5As shown, a photovoltaic panel picking and placing device includes a vehicle body 1 on which a mechanical arm assembly 2 is arranged, the mechanical arm assembly 2 includes a first arm body 21, a second arm body 22 and a lifting arm 23, the second arm body 22 is rotatably arranged on the first arm body 21, and the lifting arm 23 is slidably arranged on the second arm body 22, and the connecting end 233 of the lifting arm 23 is provided with a grabbing assembly 3 for grabbing the photovoltaic panel, and a ring-shaped flexible resistance member 25 is symmetrically fixedly connected to the first side surface and the second side surface of the second arm body 22, and the cross-section of the flexible resistance member 25 is semicircular, and a plate-shaped portion 231 is provided on the lifting arm 23, and the plate-shaped portion 231 is located between the grabbing assembly 3 and the second arm body 22, and the mounting end 232 of the lifting arm 23 is movably connected with a locking end cover 24, and the lifting arm 23 is driven to slide back and forth so that the locking end cover 24 and the plate-shaped portion 231 contact the flexible resistance member 25 in sequence.

[0024] Specifically, such as Figure 1 As shown, a walking wheel group 12 is provided at the bottom of the vehicle body 1, wherein the walking wheel group 12 can be a universal wheel 121, or an ordinary roller or track. A mounting portion 11 for mounting a mechanical arm assembly 2 is provided on the top of the vehicle body 1, and a mounting hole 13 is provided on the mounting portion 11, which is used to mount a first rotating shaft 213 of the first arm body 21, and a lifting arm 23 is slidably provided on the second rotating hole 223 of the second arm body 22. A grabbing assembly 3 is provided at the end of the mechanical arm assembly 2 for picking up and carrying photovoltaic panels, and flexible resistance members 25 are provided on the top and bottom surfaces of the second arm body 22. When the lifting arm 23 is driven to slide so that the gripping member on it When the lifting component 3 drives the photovoltaic panel to move up and down, the plate-shaped portion 231 gradually contacts the flexible resistance member 25 during the rising process of the lifting arm 23 to reduce the operating speed of the lifting arm 23, and then the lifting arm 23 gradually stops to reduce the negative acceleration when stopping. Similarly, when the lifting arm 23 descends, the locking end cover 24 can contact the flexible resistance member 25 to reduce the negative acceleration when stopping. The flexible resistance member 25, the locking end cover 24 and the plate-shaped portion 231 are used to reduce the negative acceleration at the moment when the lifting arm 23 grabs the photovoltaic panel and moves it into place and stops instantly, thereby preventing the photovoltaic panel from falling from the grabbing component 3 and being damaged.

[0025] In the above technical solution, a robotic arm assembly 2 is provided on the vehicle body 1, and a grabbing assembly 3 is provided at the end of the robotic arm assembly 2 to pick up, place and transport the photovoltaic panels, and flexible resistance members 25 are provided on the top and bottom surfaces of the second arm body 22. When the lifting arm 23 is driven to slide so that the grabbing assembly 3 thereon drives the photovoltaic panels to move up and down, the plate-shaped portion 231 gradually resists against the flexible resistance member 25 during the rising process of the lifting arm 23 to reduce the running speed of the lifting arm 23, and then the lifting arm 23 gradually stops to reduce the negative acceleration when stopping. Similarly, when the lifting arm 23 descends, the locking end cover 24 can resist the flexible resistance member 25 to reduce the negative acceleration when stopping. The flexible resistance member 25, the locking end cover 24 and the plate-shaped portion 231 are used to reduce the negative acceleration at the moment when the lifting arm 23 grabs the photovoltaic panel and transports it into place and stops instantly, thereby preventing the photovoltaic panel from falling from the grabbing assembly 3 and being damaged.

[0026] As an embodiment further provided by the present invention, the grasping assembly 3 includes a base 31 and a sliding seat 33 slidably arranged on the base 31, the base 31 is symmetrically fixedly connected with a fixed suction cup group 32, the sliding seat 33 is located between the fixed suction cup groups 32, the sliding seat 33 is fixedly connected with a movable suction cup group 34, and an elastic member 36 is symmetrically arranged in the base 31, the elastic member 36 drives the sliding seat 33 to slide so that the end of the movable suction cup group 34 is located below the end of the fixed suction cup group 32.

[0027] Specifically, such as Figure 4As shown, the sliding seat 33 is located between the two groups of fixed suction cup groups 32, so the movable suction cup group 34 provided on the sliding seat 33 is located between the fixed suction cup groups 32, and the sliding seat 33 is pushed and slid by the elastic member 36 inside the base 31 so that the end of the movable suction cup group 34 is located below the end of the fixed suction cup group 32. When the lifting arm 23 descends to vacuum the photovoltaic panel, the movable suction cup group 34 on the sliding seat 33 first contacts the surface of the photovoltaic panel, and as the lifting arm 23 continues to descend, the movable suction cup group 34 retracts into the base 31 together with the sliding seat 33 due to the friction with the surface of the photovoltaic panel, and then the fixed suction cup group 32 contacts the surface of the photovoltaic panel and adsorbs. At this time, the grasping component 3 completes the grasping of the photovoltaic panel, and the sliding The seat 33 and the elastic member 36 make the movable suction cup group 34 movable and the end portion is located below the fixed suction cup group 32. When the photovoltaic panel is placed on an uneven surface and is slightly tilted, the movable suction cup group 34 can first contact the surface of the photovoltaic panel for adsorption, and then a group of fixed suction cup groups 32 are adsorbed on the surface of the photovoltaic panel to complete the adsorption of the slightly tilted photovoltaic panel, which can avoid the problem that traditional suction cup groups are difficult to adsorb and grasp tilted plate-like objects. It should be noted that each group of fixed suction cup groups 32 shares an air source to avoid the situation where one group of fixed suction cup groups 32 is not blocked when adsorbing the tilted photovoltaic panel, resulting in pressure leakage, and the air pressure needs to be adjusted so that the two groups of suction cup groups can complete the adsorption of the photovoltaic panel surface.

[0028] As an embodiment further provided by the present invention, a connecting portion 311 for an external air pipe is symmetrically arranged on the base 31, and a main connecting hole 312 connected to the fixed suction cup group 32 is opened on the connecting portion 311. A connecting valve 35 connected to the outside world is symmetrically fixedly connected on the base 31, and a secondary connecting hole 316 is opened on the base 31 to connect the connecting valve 35 with the main connecting hole 312.

[0029] Specifically, such as Figure 4As shown, both the fixed suction cup group 32 and the movable suction cup group 34 are provided with adsorption holes 4, and the air pipe is connected to the adsorption hole 4 of the fixed suction cup group 32 through the main connecting hole 312. The connecting part 311 is used to connect the air pipe to the air source. The main connecting hole 312 and the connecting valve 35 are connected to the main connecting hole 312 through the secondary connecting hole 316. When the lifting arm 23 descends to allow the fixed suction cup group 32 and the movable suction cup group 34 to grab the photovoltaic panel, the lifting arm 23 rises, the first arm body 21 and the second arm body 22 rotate to drive the photovoltaic panel to the specified position, and then the lifting arm 23 descends to the specified position, the air source stops running, and then the connection The valve 35 is opened to allow the outside world to communicate with the main connecting hole 312 through the secondary connecting hole 316, so that the negative pressure suction in the adsorption hole 4 of the fixed suction cup group 32 disappears. Since suction still exists in the adsorption hole 4 of the movable suction cup group 34 due to air tightness after the air source disappears, the movable suction cup group 34 is still adsorbed on the photovoltaic panel, and the sliding seat 33 slides downward under the force of the photovoltaic panel. At this time, the elastic member 36 and the suction of the movable suction cup group 34 play a buffering role in the fall of the photovoltaic panel, reducing the speed at which the photovoltaic panel is placed, reducing the impact on it when it is placed, and avoiding it from being damaged by a large impact when it is lowered from the grasping component 3.

[0030] As a further embodiment provided by the present invention, a hollow cavity 313 is opened in the base 31, the sliding seat 33 is slidably set in the hollow cavity 313, a sliding groove 314 is symmetrically opened in the hollow cavity 313, and a sliding part 331 is symmetrically set on the sliding seat 33, and the sliding part 331 is slidably set in the sliding groove 314.

[0031] Specifically, such as Figure 4 As shown, a hollow cavity 313 is opened in the base 31, and the sliding seat 33 is slidably set in the hollow cavity 313. When the sliding seat 33 slides in the hollow cavity 313, the sliding part 331 slides in the sliding groove 314, and the sliding part 331 and the sliding groove 314 are used to increase the sliding stability of the sliding seat 33.

[0032] As a further embodiment provided by the present invention, a penetration hole 315 communicating with the hollow cavity 313 is defined on the base 31 .

[0033] Specifically, the base 31 is provided with a penetration hole 315 connected to the hollow cavity 313 , and the air pipe can be passed through the penetration hole 315 into the hollow cavity 313 to be installed on the movable suction cup group 34 to provide suction for the adsorption hole 4 of the movable suction cup group 34 .

[0034] As a further embodiment provided by the present invention, a first rotating hole 211 is defined on the first arm 21 , and a second rotating shaft 221 is provided on the second arm 22 . The second rotating shaft 221 is rotatably disposed in the first rotating hole 211 .

[0035] Specifically, such as Figure 3 As shown, a first rotating hole 211 is provided on the first arm body 21, and a second rotating shaft 221 is provided on the second arm body 22. When the second arm body 22 rotates, the second rotating shaft 221 rotates in the first rotating hole 211. The second rotating shaft 221 and the first rotating hole 211 are used to increase the rotational stability of the second arm body 22 and reduce the impact when the robotic arm assembly 2 moves.

[0036] As an embodiment further provided by the present invention, a rotation groove 212 is provided on the first arm body 21, and an inclined support portion 222 is provided on the second rotating shaft 221. The first end of the support portion 222 is connected to the second arm body 22, and the second arm body 22 is driven to rotate so that the support portion 222 rotates along the rotation groove 212.

[0037] Specifically, such as Figure 3 As shown, a rotation groove 212 is provided on the first arm body 21, and an inclined support portion 222 is provided on the second rotating shaft 221. The first end of the support portion 222 is connected to the second arm body 22. When the second arm body 22 rotates, the support portion 222 rotates along the rotation groove 212 to further increase the rotational stability of the second arm body 22. Secondly, the support portion 222 can also be regarded as a rib to increase the self-strength of the second arm body 22 and increase the service life of the second arm body 22.

[0038] Working principle: First, the robotic arm assembly 2 is driven by the motor to move, so that the lifting arm 23 descends to vacuum the photovoltaic panel. The movable suction cup group 34 on the sliding seat 33 first contacts the surface of the photovoltaic panel, and as the lifting arm 23 continues to descend, the movable suction cup group 34 retracts into the base 31 together with the sliding seat 33 due to the friction with the surface of the photovoltaic panel, and then the fixed suction cup group 32 contacts the surface of the photovoltaic panel and adsorbs. At this time, the grasping assembly 3 completes the grasping of the photovoltaic panel, and uses the sliding seat 33 and the elastic member 36 to make the movable suction cup group 34 movable and the end portion located below the fixed suction cup group 32. When the photovoltaic panel is placed on an uneven surface and slightly tilted, the movable suction cup group 34 can first contact the surface of the photovoltaic panel for adsorption, and then a group of fixed suction cup groups 32 are adsorbed on the surface of the photovoltaic panel to complete the adsorption of the slightly tilted photovoltaic panel. The lifting arm 23 rises, and during the rising process of the lifting arm 23, the plate-shaped portion 231 gradually conflicts with the flexible resistance member 25 to lower the lifting arm 23, and then the lifting arm 23 gradually stops to reduce the negative acceleration when stopping, then the first arm 21 and the second arm 22 rotate to drive the photovoltaic panel to the specified position, then the lifting arm 23 descends to the specified position, the air source stops running, and then the connecting valve 35 is opened to allow the outside to communicate with the main connecting hole 312 through the secondary connecting hole 316, so that the negative pressure suction in the adsorption hole 4 of the fixed suction cup group 32 disappears. After the air source disappears, the adsorption hole 4 of the movable suction cup group 34 is still airtight. Although there is suction, the movable suction cup group 34 is still adsorbed on the photovoltaic panel, and the sliding seat 33 slides downward due to the force of the photovoltaic panel. At this time, the suction of the elastic member 36 and the movable suction cup group 34 acts as a buffer for the fall of the photovoltaic panel. When the lifting arm 23 descends, the locking end cover 24 can resist the flexible resistance member 25 to reduce the negative acceleration when stopping; when the second arm body 22 rotates, the support part 222 rotates along the rotation groove 212 to further increase the rotation stability of the second arm body 22.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
