Description

Technical Field

[0001] The utility model relates to the technical field of battery string production, in particular to a grabbing piece rotating device. Background Art

[0002] The positive and negative metal contacts of the back-contact cell are distributed on the back of the cell. In a photovoltaic module made of back-contact cells, the number of cells is an even number, and the number of welding strips on the surface of the cell is an even number. The cells at the same position in two adjacent cell strings are placed in opposite directions. Therefore, when making two adjacent cell strings, the placement angle of all cells in one of the cell strings needs to be adjusted.

[0003] In the prior art, the battery cells used in the battery string are usually bisection battery cells, that is, bisection battery cells that are evenly divided into two pieces from a whole battery cell. After the whole battery cell is divided into bisection battery cells, the two bisection battery cells are very close to each other. Using a robot to grab a single bisection battery cell and rotate it 180 degrees to adjust the placement angle of the battery cell is inefficient and affects the production speed of the battery string.

[0025] The technical solution and technical effects of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0026] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature can include the first and second features directly contacting, and can also include the first and second features not directly contacting but contacting through another feature between them. Moreover, the first feature "above", "above" and "above" the second feature include the first feature directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0027] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must be provided with a specific direction, constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present utility model. It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish the first feature from the second feature, and do not necessarily require or imply any such actual relationship or order between these features.

[0028] like Figure 1As shown, in the utility model, the battery cell is two half-piece battery cells cut from a whole battery cell, and the two battery cells belonging to the same whole battery cell are close to each other. Before the placement angle is adjusted, the chamfers of the two battery cells are far away from each other, and after the placement angle is adjusted, the chamfers of the two battery cells are close to each other. The gripping and rotating device provided by the utility model is used to adjust the placement angle of the two battery cells and rotate the two battery cells 180 degrees respectively.

[0029] like Figure 2 and Figure 3 As shown, the grab piece rotating device includes: a mounting plate 10, a distance adjustment mechanism, a first rotating mechanism 31, a second rotating mechanism 32, a first suction cup 41 and a second suction cup 42. The distance adjustment mechanism is arranged on the mounting plate 10. The distance adjustment mechanism includes a first moving block 21 and a second moving block 22 that can reciprocate along a first horizontal direction. The first moving block 21 and the second moving block 22 are slidably connected to the mounting plate 10. The first rotating mechanism 31 and the second rotating mechanism 32 are respectively arranged on the first moving block 21 and the second moving block 22. The first suction cup 41 and the second suction cup 42 are respectively connected to the rotating end of the first rotating mechanism 31 and the rotating end of the second rotating mechanism 32. When the distance adjustment mechanism controls the first moving block 21 and the second moving block 22 to approach or move away from each other, the first suction cup 41 and the second suction cup 42 can approach or move away from each other. The first rotating mechanism 31 and the second rotating mechanism 32 are respectively used to control the rotation angles of the first suction cup 41 and the second suction cup 42. The first moving block 21 and the second moving block 22 are both slidably connected to the mounting plate 10 through a slider and a guide rail, the guide rail is fixed to the bottom of the mounting plate 10, and a limit block is provided next to the end of the guide rail to prevent the first moving block 21 and the second moving block 22 from being separated from the guide rail. The first rotating mechanism 31 and the second rotating mechanism 32 can be electric, hydraulic, or pneumatic rotating devices.

[0030] In the present invention, after the first suction cup 41 and the second suction cup 42 each absorb a battery cell, the distance adjustment mechanism separates the two battery cells by a distance until the two battery cells do not collide with each other when rotating, the first rotation mechanism 31 and the second rotation mechanism 32 respectively rotate the two battery cells 180 degrees, the distance adjustment mechanism then brings the two battery cells closer by a distance, the first suction cup 41 and the second suction cup 42 release the two battery cells, and the placement angle adjustment of the two battery cells is completed. The gripping and rotating device can adjust the placement angles of the two battery cells at the same time, and the battery cell angle adjustment efficiency is high.

[0031] Recombination Figure 4 and Figure 5In an optional embodiment of the utility model, the distance adjustment mechanism further includes a distance adjustment motor 23, a first rack 24 and a second rack 25. The distance adjustment motor 23 is fixed on the mounting plate 10. The first rack 24 and the second rack 25 are respectively fixed on the first moving block 21 and the second moving block 22.

The first rack 24 and the second rack 25 are arranged in parallel and are respectively located on both sides of the gear. When the distance adjustment motor 23 is working, the gear rotates, driving the first rack 24 and the second rack 25 to move simultaneously. The first rack 24 and the second rack 25 respectively drive the first moving block 21 and the second moving block 22 to move simultaneously, so that the first suction cup 41 and the second suction cup 42 move simultaneously to adjust the distance.

When the distance adjustment motor 23 is working, the driving wheel 26 rotates, drives the belt 28 to rotate, and drives the first moving block 21 and the second moving block 22 to move simultaneously, so that the first suction cup 41 and the second suction cup 42 move simultaneously to adjust the distance.

[0033] In the utility model, the first rack 24 and the second rack 25 are used to adjust the distance between the first suction cup 41 and the second suction cup 42 compared to using the belt 28. The first rack 24 and the second rack 25 occupy a small space, and a shorter mounting plate 10 can meet the assembly requirements of the first rack 24 and the second rack 25. The cost of the first rack 24 and the second rack 25 is higher than that of the belt 28.

[0034] In an optional embodiment of the utility model, a proximity switch 50 is provided beside the first suction cup 41 and the second suction cup 42, which is used to detect the distance between the first suction cup 41 and the second suction cup 42 and the battery sheet and provide instructions to control the working state of the first suction cup 41 and the second suction cup 42. The proximity switch 50 is fixed to the first moving block 21 and the second moving block 22, or to the main body of the first rotating mechanism 31 and the second rotating mechanism 32 that does not participate in the rotation.

[0035] In an optional embodiment of the present invention, the first rotating mechanism 31 and the second rotating mechanism 32 are rotating cylinders.

[0037] In the present invention, the first suction cup 41 and the second suction cup 42 may be contact suction cups or non-contact suction cups. Preferably, the first suction cup 41 and the second suction cup 42 are Bernoulli suction cups.

[0038] like Figure 8 As shown, in an optional embodiment of the utility model, the grabbing sheet rotating device further includes a translation driving mechanism 60, the driving end of the translation driving mechanism 60 is drivingly connected to the mounting plate 10, driving the mounting plate 10 to reciprocate along the first horizontal direction or the second horizontal direction, and the first horizontal direction and the second horizontal direction are perpendicular. After the grabbing sheet rotating device adjusts the placement angle of the two battery sheets, the translation driving mechanism 60 can be used to transport the battery sheets to the next station, so that the robot can grab the adjusted battery sheets.
