Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic equipment, and in particular relates to a mechanism capable of grasping, lifting and transporting a solar cell string. Background Art

[0002] In photovoltaic equipment, a transport mechanism is required to transport the battery string to the next process, and at the same time, it must ensure that the battery cells do not break during the transport process. The existing transport mechanism has the following defects in the process of transporting the battery string: 1. The overall structure is relatively complex, occupies a large space, and has a high production cost; 2. The position accuracy of the battery string after transport is poor and cannot be well adapted to the position; 3. The battery cells of the battery string are prone to breakage or hidden cracks during the transport process.

[0003] For example, a Chinese utility model patent with authorization announcement number CN 216638111 U discloses a suction cup assembly, a battery string grasping mechanism and a battery string handling device, which can grasp and handle a battery string group composed of multiple battery strings, but its disadvantages are: complex structure, large space occupation and high production cost.

[0007] Preferably, the translation assembly comprises a linear module mounted on the crossbeam, and the linear module is slidably connected to a connecting member via a slider.

[0008] Preferably, the lifting assembly includes a bracket connected to the connecting member 1, and at least one set of ball screw linear transmission mechanism is arranged on the bracket. The ball screw linear transmission mechanism is slidably connected to the connecting member 2, and the lower end of the connecting member 2 is connected to the linear rail mounting plate through a connecting plate.

[0009] Preferably, the ball screw linear transmission mechanism includes a screw and a linear guide rail 2 arranged on a bracket, the upper end of the screw is connected to a driving member 2 through a coupling, a screw nut is provided on the screw, the screw nut is connected to the connecting member 2, and the linear guide rail 2 is slidably connected to the connecting member 2 through a slider 2.

[0010] Preferably, two groups of the ball screw linear transmission mechanisms are provided.

[0011] Preferably, each of the two lead screws is provided with a synchronous pulley, and the two synchronous pulleys are connected by a transmission belt.

[0012] Preferably, the first driving member and the second driving member are both servo motors.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The driving member 1 drives the bidirectional screw to rotate, so that the clamps on the two clamp fixing plates gradually approach to clamp the battery string and make contact with the battery cells; by rotating the driving member 1 in the opposite direction, the clamps on the two clamp fixing plates gradually move away from each other to release the battery string, thus achieving more reliable grasping and releasing, avoiding damage to the battery string, and the grasping assembly is installed at the lower end of the lifting assembly, and its structure occupies little space, which is convenient for equipment integration;

[0015] 2. By symmetrically installing two sets of ball screw linear transmission mechanisms on both sides of the translation assembly, the stability of the grab assembly is improved to avoid deviation. At the same time, the battery string is lifted to a safe height by the lifting assembly and then translated and transported, which improves the overall safety and reliability;

[0016] 3. When the battery string is translated, it is translated through the linear module, which has high reliability and can be directly installed on the rack, with simple structure and easy installation;

[0017] 4. The battery string can be clamped by the clamping claw, which can clamp battery strings of different sizes and has a wide range of uses;

[0018] In summary, the utility model clamps the battery string through the grasping assembly, and at the same time drives the battery string on the grasping assembly to rise through the lifting assembly, and then the translation assembly drives the battery string to move to the next process, thereby reducing the movement space, and no breakage occurs during the transportation of the battery cells, thereby improving the product yield and ensuring work efficiency.

[0028] In this embodiment, the bidirectional screw rod 12 is driven to rotate by the driving member 11, so that the claws 15 on the two claw fixing plates 14 gradually approach to clamp the battery string and come into contact with the battery cells; by rotating the driving member 11 in the opposite direction, the claws 15 on the two claw fixing plates 14 gradually move away from and release the battery string, thereby achieving more reliable grasping and releasing and avoiding damage to the battery string. The grasping component 1 is installed at the lower end of the lifting component 3, and its structure occupies a small space, which is convenient for equipment integration.

[0029] In addition, Teflon or silicone can be pasted on the clamping jaws 15 to protect the battery string and prevent it from slipping during the clamping process.

[0030] Embodiment 2:

[0031] like Figure 4-5 As shown, a grasping lifting and transporting mechanism is different from Example 1 in that the translation assembly 2 includes a linear module 21 installed on the beam 6, and the linear module 21 is slidably connected to the connecting member 5 through a slider.

[0032] Furthermore, the lifting assembly 3 includes a bracket 39 fixedly connected to the connecting member 1 5, and at least one set of ball screw linear transmission mechanism is arranged on the bracket 39. The ball screw linear transmission mechanism is slidably connected to the connecting member 2 37, and the lower end of the connecting member 2 37 is connected to the linear rail mounting plate 16 through the connecting plate 38.

[0033] Furthermore, the ball screw linear transmission mechanism includes a screw 33 and a linear guide rail 34 arranged on a bracket 39, the upper end of the screw 33 is connected to a driving member 31 through a coupling, a screw nut 36 is provided on the screw 33, the screw nut 36 is connected to a connecting member 37, and the linear guide rail 34 is slidably connected to the connecting member 37 through a slider 35.

[0038] By moving the lifting assembly 3 and the translation assembly 2, the grabbing assembly 1 is moved to the position of the battery string, and the driving member 11 drives the bidirectional screw 12 to rotate, so that the two jaws 15 on the jaw fixing plates 14 gradually approach to clamp the battery string and make contact with the battery cells, thus realizing a more reliable grabbing method; then the driving member 2 31 in the lifting assembly 3 drives the screw 33 to rotate, and then drives the battery string on the grabbing assembly 1 to rise through the connecting member 2 37 and the connecting plate 38, and then translates and transports it when it is lifted to a safe height, and then starts the driving member 3 22 on the linear module 21, and drives the lifting assembly 3 and the battery string on the grabbing assembly 1 to translate to the next process position through the linear module 21, and then the driving member 11 is rotated in the opposite direction, and the jaws 15 on the two jaw fixing plates 14 gradually move away from the released battery string.
