[0026] The following is combined with Figure 1-8 This application is described in further detail.

[0027] Reference Figures 1 to 3The embodiment of the present application discloses a material unloading device of a battery cell heating device 100, including a material picking robot 1 and a battery cell transfer mechanism 2, wherein the material picking robot 1 is used to grab the battery cell 200 on the heating tray 101 in the battery cell heating device 100, and transfer the battery cell 200 to the battery cell transfer mechanism 2, and the battery cell transfer mechanism 2 is used to move the battery cell 200 horizontally from the inside to the outside; the material picking robot 1 includes a Z-axis lifting platform 11, a horizontal lifting arm 12, a mounting frame 13 and a plurality of mechanical grippers 14, the Z-axis lifting platform 11 is used to drive the horizontal lifting arm 12 to rise and fall, the mounting frame 13 is arranged on the horizontal lifting arm 12, and the plurality of mechanical grippers 14 are arranged on the mounting frame 13.

[0028] The Z-axis lifting platform 11 of this embodiment has only lifting function and does not have horizontal movement function. The number of the mechanical clamps 14 is specifically eight, which are arranged horizontally in parallel, greatly improving the material unloading efficiency and meeting the needs of large-scale production.

[0029] The battery cell heating device 100 is provided with a fork mechanism, which can selectively push out the heating tray 101. By controlling the pushing distance, all the battery cells 200 on the heating tray 101 can be grabbed out by relying on the lifting action of the material picking robot 1 without changing the horizontal position of the material picking robot 1.

[0030] Reference Figures 4 to 6 The mechanical clamp 14 includes a two-way opening and closing cylinder 141, a first battery cell pressing cylinder 142, a second battery cell pressing cylinder 143, a first L-shaped clamp 144 and a second L-shaped clamp 145. The two-way opening and closing cylinder 141 is used to drive the first L-shaped clamp 144 and the second L-shaped clamp 145 to clamp and move away from each other to grab or release the battery cell 200. The first battery cell pressing cylinder 142 is used to press the battery cell 200 on the first L-shaped clamp 144, and the second battery cell pressing cylinder 143 is used to press the battery cell 200 on the second L-shaped clamp 145. The first battery cell pressing cylinder 142 and the second battery cell pressing cylinder 143 can stably press the battery cell 200 on the first L-shaped clamp 144 and the second L-shaped clamp 145 to prevent displacement during the transfer process, which affects the transfer accuracy, and can also prevent the battery cell 200 from falling.

[0031] Reference Figure 5 and Figure 6, anti-collision detection frames 146 are provided on both cylinder shafts of the two-way opening and closing cylinder 141, and the first L-shaped clamping jaw 144 and the second L-shaped clamping jaw 145 are elastically slidably arranged on the anti-collision detection frames 146 on both sides, respectively, and a displacement detector 147 is provided on the anti-collision detection frame 146 for detecting the movement of the first L-shaped clamping jaw 144 and the second L-shaped clamping jaw 145 on the anti-collision detection frame 146. By arranging elastic parts such as springs, the first L-shaped clamping jaw 144 and the second L-shaped clamping jaw 145 have a certain floating elasticity in the vertical direction. When the first L-shaped clamping jaw 144 or the second L-shaped clamping jaw 145 is blocked in the vertical direction, it will be displaced upward relative to the anti-collision detection frame 146. At this time, when the displacement detector 147 detects the displacement, it is considered that the first L-shaped clamping jaw 144 or the second L-shaped clamping jaw 145 has collided with an external object, and an alarm signal can be generated, and the machine is stopped for inspection, thereby improving the safety of the unloading device.

[0032] Reference Figure 2 and Figure 3 In this embodiment, the horizontal lifting arm 12 is relatively long. Due to the heavy weight of the mounting frame 13 and the multiple mechanical grippers 14, the center of gravity is seriously offset, which greatly affects the lifting of the Z-axis lifting platform 11. To this end, the material-retrieving manipulator 1 in this embodiment also includes an upper hanging plate 15, a counterweight block 16, a belt 17 and a guide slide 18. The upper hanging plate 15 is fixedly arranged on the frame of the battery core heating device 100. The belt 17 passes through the pulleys at both ends of the upper hanging plate 15, and the two ends are respectively connected to the counterweight block 16 and the middle part of the horizontal lifting arm 12. The counterweight block 16 is slidably arranged in the guide slide 18. By setting the counterweight block 16 to pull the center of gravity of the load of the Z-axis lifting platform 11 back to the center line position and balance the weight on both sides of the belt 17, the requirements for the Z-axis lifting platform 11 can be reduced. The material-retrieving manipulator 1 also includes an auxiliary guide rail 19, which is arranged on the frame of the battery core heating device 100, and the horizontal lifting arm 12 is slidably arranged on the auxiliary guide rail 19. By adding the auxiliary guide rail 19, the horizontal lifting arm 12 can move more smoothly and further reduce the adverse effects of the center of gravity offset.

[0033] Reference Figure 7 and Figure 8The battery cell transfer mechanism 2 includes a Y-axis moving platform 21 and a battery cell fixing fixture 22. The Y-axis moving platform 21 is used to drive the battery cell fixing fixture 22 to move horizontally, and the battery cell fixing fixture 22 is used to receive and fix the battery cell. The battery cell fixing fixture 22 includes a bottom plate 221 and a plurality of guide limit blocks 222 arranged on the bottom plate 221. The plurality of guide limit blocks 222 are used to perform peripheral positioning on the battery cell. The guide limit blocks 222 also have a centering effect, which plays a role in secondary positioning of the battery cell. A battery cell sensor 23 is also provided on the bottom plate 221, which is used to detect the presence or absence of the battery cell, to prevent the material removal robot 1 from failing to release the material, causing the battery cell transfer mechanism 2 to be transported empty, thereby improving safety and intelligence.

[0034] The specific process of the feeding device of the present application grabbing the battery cell is as follows: first, one of the heating trays 101 is pushed out a distance, the Z-axis lifting platform 11 drives the horizontal lifting arm 12 and the mechanical clamp 14 to descend, and reaches the battery cell position, the two-way opening and closing cylinder 141 is actuated, the first L-shaped clamp 144 and the second L-shaped clamp 145 are clamped together to grab the battery cell 200, and then the first battery cell pressing cylinder 142 and the second battery cell pressing cylinder 143 are actuated to press the battery cell 200; then the Z-axis lifting platform 11 drives the horizontal lifting arm 12, the mechanical clamp 14 and the battery cell 200 to rise; the heating tray 101 is retracted, and the Z-axis lifting platform 11 drives the horizontal lifting arm 12, the mechanical clamp 14 and the battery cell 200 to descend, and the battery cell 200 is placed on the battery. On the cell fixing fixture 22, the first cell pressing cylinder 142 and the second cell pressing cylinder 143 are actuated, and the cell 200 is no longer pressed, the two-way opening and closing cylinder 141 is actuated, the first L-shaped clamp 144 and the second L-shaped clamp 145 are opened, and the cell 200 is released, and the Z-axis lifting platform 11 drives the horizontal lifting arm 12 and the mechanical clamp 14 to rise and return to the initial position; the Y-axis moving platform 21 drives the cell fixing fixture 22 to move horizontally, and the cell 200 is transferred out, and the robot of the next process takes away the cell 200 on the cell fixing fixture 22; repeat the above actions, after the cell 200 on the current heating tray 101 is taken out, the other heating tray 101 is unloaded to achieve continuous unloading and improve unloading efficiency.

[0035] The implementation principle of the present application is as follows: the material picking robot 1 and the battery cell transfer mechanism 2 provided in the present application have a short stroke, a small size, and are easy to arrange; and both the material picking robot 1 and the battery cell transfer mechanism 2 are single-axis moving mechanisms with a simple moving trajectory, and the requirement for avoiding surrounding parts is greatly reduced. Since a horizontal lifting arm 12 is provided, the Z-axis lifting platform 11 can be arranged away from the heating tray 101, and is not likely to affect the entry and exit of the heating tray 101; the material picking robot 1 and the battery cell transfer mechanism 2 can grab or transfer multiple battery cells 200 at a time, thereby improving the unloading efficiency.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
