The following embodiments are only used to more clearly illustrate the technical solution of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0023] Embodiment 1:

[0024] As Figures 1-3 shown, this embodiment provides a conveying mechanism adapted to high - speed sorting of multi - gear battery cells, including a sorting component 1, a feeding component 5, and a discharging component 6. The sorting component 1 includes a bracket 2, a walking component 3 arranged on the bracket 2, and a manipulator 4 arranged on the walking component 3; the feeding component 5 and the discharging component 6 are both arranged on the side of the bracket 2; for the target battery cell at a predetermined position on the feeding component 5, the walking component 3 moves the manipulator 4 to the predetermined position on the bracket 2, picks up the target battery cell and places it at the predetermined position on the discharging component 6 to achieve multi - gear battery cell sorting.

[0025] The feeding component 5 includes a plurality of first conveyor lines 51 arranged in parallel. The first conveyor lines 51 convey in the direction approaching the bracket 2; the first conveyor lines 51 are used to transport the fully - loaded battery cell trays 7, and battery cell slots are evenly distributed along rows and columns on the battery cell trays 7. A first photoelectric sensor is arranged on the first conveyor lines 51, and the first photoelectric sensor is used to detect whether the battery cell tray 7 reaches the predetermined position on the first conveyor lines 51. After the battery cell tray 7 reaches the predetermined position, the first conveyor lines 51 stop working and the manipulator 4 starts working.

[0026] The loading component 5 includes a plurality of second conveying lines 52 arranged in parallel. The second conveying lines 52 convey in a direction away from the bracket 2. The first conveying line 51 is used to transport the empty battery cell trays 7. The main function of the second conveying lines 52 is to transport the empty battery cell trays 7 back. Here, moving the battery cell trays 7 on the first conveying line 51 to the second conveying lines 52 can be done manually or by setting additional components, which will not be elaborated here.

[0027] The unloading component 6 includes a plurality of conveyor belts 61 arranged in parallel. Each conveyor belt 61 corresponds to a battery cell of a certain grade. The conveyor belts 61 convey in a direction away from the bracket 2. Limiting members 62 are evenly spaced on the conveyor belts 61, and battery cell pits are formed between adjacent limiting members 62. By the manipulator 4 picking up the target battery cells and placing them on the corresponding conveyor belts 61, only one grade of battery cells appears on each conveyor belt 61, so as to summarize and send out the battery cells of the same grade.

[0028] A second photoelectric sensor is arranged in the battery cell pit closest to the bracket 2 on the conveyor belt 61. The second photoelectric sensor is used to detect whether there is a battery cell in the battery cell pit. When the second photoelectric sensor detects that there is a battery cell in the first battery cell pit close to the bracket 2, the conveyor belt 61 works, moving the first battery cell pit to the second battery cell pit, and so on, always ensuring that the first battery cell pit is empty.

[0029] The traveling component 3 includes an orbital box 31 arranged on the bracket 2. A first rectangular groove 32 is opened at the top of the orbital box 31 along the traveling direction. A second rectangular groove 33 is opened at the bottom of the first rectangular groove 32 along the traveling direction. Guide rails 34 are arranged on both sides of the first rectangular groove 32 along the traveling direction, and sliders 35 are configured on the guide rails 34. Mounting plates 36 are fixed to the tops of the two sliders 35. A rack 37 is arranged in the second rectangular groove 33 along the traveling direction, and a gear 38 is meshed with the rack 37. A motor 39 is arranged on the top of the mounting plate 36. The main shaft of the motor 39 passes through the mounting plate 36 and the first rectangular groove 32 to the second rectangular groove 33 and is connected to the gear 38. The manipulator 4 is fixed to the top of the mounting plate 36. The function of the traveling component 3 is to drive the manipulator 4 to move, thereby expanding the working range of the manipulator 4.

[0030] The manipulator 4 includes a robotic arm 41, a lifting component 42, and a clamping part 43. The robotic arm 41 includes a vertical arm 411, a first cross arm 412, and a second cross arm 413. The bottom of the vertical arm 411 is fixed to the traveling component 3. Two ends of the first cross arm 412 are respectively rotatably connected to the top of the vertical arm 411 and one end of the second cross arm 413. The other end of the second cross arm 413 is fixed to the lifting component 42, and the output end of the lifting component 42 is fixed to the clamping part 43.

[0031] The lifting component 42 is an electric push rod or a telescopic cylinder.

[0032] The clamping part 43 includes a spring assembly 431 and a jaw cylinder 432. The spring assembly 431 includes a frame body 4311 and a spring column 4312. The spring column 4312 includes a column shell, a column pin embedded in the column shell, and a spring sleeved on the column pin; the column shell is fixed to the inner wall of the bottom of the frame body 4311, the column pin passes through the bottom of the frame body 4311 and is connected to the jaw cylinder 432, and both ends of the spring are in contact with the outer wall of the bottom of the frame body 4311 and the top of the jaw cylinder 432 respectively. Due to the buffering effect of the spring column 4312, it avoids the clamping part 43 from squeezing the battery cell during operation; at the same time, a photoelectric sensor can also be added to the clamping part 43 to detect the distance of surrounding objects and achieve the anti-collision function.

[0033] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
