DETAILED DESCRIPTION
[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0038] Embodiment one
[0039] In the prior art, in order to improve the efficiency of the recycling process, the person skilled in the art usually uses a mechanical arm equipped with a gripper to grab and remove the junction box on the photovoltaic panel. Then, the mechanical arm moves to place the removed junction box in the storage container. However, during the movement of the mechanical arm, the junction box may shake on the gripper, which sometimes causes the junction box to fall accidentally, thereby affecting the smooth progress of the subsequent process.
[0040] Therefore, in order to solve the above problems and realize the function of improving the stability of the junction box on the mechanical arm, the utility model discloses a junction box removing mechanism for waste photovoltaic panels, referring to Figure 1 、 Figure 2 and Figure 4 , including a processing table 1 and a mechanical arm 6, the processing table 1 is provided with a positioning frame, the mechanical arm 6 is movably connected to the positioning frame, and one end of the mechanical arm 6 towards the processing table 1 is provided with a gripper 10, the gripper 10 is suitable for clamping the junction box on the photovoltaic panel, specifically, one end of the mechanical arm 6 provided with the gripper 10 is also provided with a pressing mechanism, including a pressing rod 14 and a telescopic rod, the pressing rod 14 penetrates the midpoint of the central axis of the end of the mechanical arm 6, and the pressing rod 14 is located on the inner side of the gripper 10, the telescopic rod is arranged in the interior of the mechanical arm 6, and one end of the telescopic rod is connected with the pressing rod 14, the telescopic rod is suitable for pushing the pressing rod 14 out of the mechanical arm 6, wherein when the telescopic rod pushes the pressing rod 14 out of the mechanical arm 6, the pressing rod 14 abuts against the top of the junction box.
[0041] In this embodiment, by the arrangement of the pressing mechanism, when the junction box is clamped by the gripper 10 and the mechanical arm 6 starts to move on the positioning frame, the pressing rod 14 will be stretched out from the mechanical arm 6 under the driving of the telescopic rod and abut against the junction box clamped on the gripper 10. At this time, the pressing rod 14 and the gripper 10 support can form a longitudinal clamping force, and at the same time, the two grippers 10 can produce a transverse clamping force, so as to limit the junction box on the gripper 10 to avoid the situation that the junction box falls from the mechanical arm 6 due to shaking.
[0042] For example, when the jaw 10 successfully clamps the wire box, the wire box is in the clamping state of the jaw 10, but only by the clamping force of the jaw 10, when the mechanical arm 6 moves, the wire box may still shake due to its own weight, inertia and external vibration and other factors. At this time, through the action of the telescopic rod, the telescopic rod pushes the pressing rod 14 out of the mechanical arm 6, so that the pressing rod 14 moves towards the top of the wire box, and when the pressing rod 14 collides with the top of the wire box, it will exert a downward pressure on the wire box. The pressure and the clamping force of the jaw 10 on the wire box together provide a more stable fixation for the wire box. Specifically, the jaw 10 mainly constrains the wire box from the side (horizontal direction), which generates a horizontal clamping force to prevent the wire box from moving in the horizontal direction; and the pressing rod 14 applies pressure to the wire box from the top (vertical direction), which limits the movement of the wire box in the vertical direction.
[0043] It can be understood that the jaw 10 is provided with at least two, and the jaw 10 is L-shaped. When the jaw 10 clamps the wire box, the end of the jaw 10 needs to be inserted into the gap between the wire box and the photovoltaic panel, and then the two jaws 10 are tightened, and the mechanical arm 6 is lifted upward, so as to disassemble the wire box.
[0044] As preferred, the surface of the jaw 10 is provided with a convex strip 17, wherein the convex strip 17 is arranged in an inclined manner. Through this structure, the friction between the jaw 10 and the wire box is increased, so that the jaw 10 is more stable when clamping the wire box and is not easy to slip off. At the same time, the setting of the convex strip 17 can also play a guiding role, so that the jaw 10 is more easily inserted into the gap between the wire box and the photovoltaic panel, and the disassembly efficiency is improved.
[0045] At the same time, the inside of the mechanical arm 6 is provided with a driving member for controlling the telescopic rod, and the driving member can be a cylinder or a motor.
[0046] Embodiment two
[0047] On the basis of embodiment one, in order to improve the stability of the jaw 10 in the tightening and loosening process, referring to Figure 3 The utility model also includes a connecting column 12 and a storage cavity 16 for connecting the connecting column 12 and the storage cavity 16, the connecting column 12 is arranged on the side of the jaw 10 towards the mechanical arm 6, the storage cavity 16 is opened on the mechanical arm 6, and the opening of the storage cavity 16 and the connecting column 12 are located in the same plane.
[0048] In the embodiment, the connecting column 12 is inserted into the receiving cavity 16, and a spring is sleeved on the connecting column 12 and abuts between the clamping jaw 10 and the opening of the receiving cavity 16. Through the arrangement, when the clamping jaw 10 performs the tightening or loosening action, the connecting column 12 slides in the receiving cavity 16, and the spring sleeved on the connecting column 12 generates an elastic force on the clamping jaw 10, so that the movement of the clamping jaw 10 is more stable and smooth. When the clamping jaw 10 is tightened, the spring is compressed and stores elastic potential energy; when the clamping jaw 10 is loosened, the spring releases the elastic potential energy and assists the clamping jaw 10 to return to the initial position, thereby avoiding the situation that the clamping jaw 10 deviates or moves unstably due to inertia or other external force factors, and further improving the stability and reliability of the entire clamping process.
[0049] It should be noted that the clamping jaw 10 is externally connected with the driving part 11 away from the mechanical arm 6, the driving part 11 includes a telescopic arm, the telescopic arm drives the clamping jaw 10 to perform horizontal reciprocating movement, and the telescopic arm is controlled by an external cylinder or motor.
[0050] Embodiment three
[0051] On the basis of the embodiment two, in order to further improve the stability of the clamping jaw 10, referring to Figures 2-3 The utility model also includes a guide assembly, the guide assembly includes a guide part and a limiting block 13, the guide part is arranged on the mechanical arm 6 and is located above the clamping jaw 10, a guide groove 15 is formed on the side of the guide part facing the clamping jaw 10, the limiting block 13 is arranged on the top of the clamping jaw 10 and is embedded in the guide groove 15, and the guide groove 15 is located in the same direction as the connecting column 12.
[0052] In the embodiment, the guide groove 15 and the limiting block 13 cooperate to guide and limit the movement track of the clamping jaw 10, so that the clamping jaw 10 can move stably along the track of the guide groove 15 during the tightening and loosening process, and the situation that the clamping jaw 10 shakes or deviates during the movement is avoided, and the stability and accuracy of the clamping jaw 10 clamping the line box are further improved.
[0053] Further, in order to ensure that the guide assembly can more accurately guide the movement of the clamping jaw 10, the structure of the guide groove 15 of the guide part can be optimized. A wear-resistant layer is arranged in the guide groove 15, such as a wear-resistant plastic or metal coating, so that the wear of the limiting block 13 when sliding in the guide groove 15 is reduced, and the service life of the guide assembly is prolonged. At the same time, a buffer device, such as a rubber buffer pad, is arranged at both ends of the guide groove 15, so that when the limiting block 13 moves to both ends of the guide groove 15, the buffer device can absorb impact energy and prevent the limiting block 13 from colliding with the end of the guide groove 15, thereby avoiding damage caused by the collision and ensuring the normal operation of the guide assembly.

[0057] Further, the transverse shaft 3 is provided with a first lead screw 4, and the first lead screw 4 is transversely arranged in the moving piece 5 to drive the moving piece 5 to make horizontal reciprocating motion along the width direction of the machining table 1, so that when the first lead screw 4 rotates, the mechanical arm 6 can be driven to displace horizontally on the X axis.
