Description

Technical Field

[0001] The present invention relates to a pulling belt device for rapid cell type change positioning, belonging to the field of lithium battery transportation. Background Art

[0002] With the rapid development of the lithium battery industry, square lithium-ion batteries have currently become the preferred choice for many digital and electrical products. Compared with cylindrical batteries, such batteries have stronger plasticity and can also be customized according to the specific requirements of the products to be equipped. This has also resulted in different sizes of such batteries. There is no clear standard division like that of cylindrical batteries, neither in the manufacturing process nor in the application standards. In the production process of square lithium-ion batteries, due to the prevalence of customized production, there are thousands of models of such batteries on the market. It is difficult to uniformly divide the processing technology and transportation equipment. Different batteries need to be transported on different transportation lines, and the existing conveyor lines can usually only transport one model of battery at a time, resulting in reduced efficiency in transporting different models of batteries and being prone to confusion during transportation. Once the manipulator makes a wrong sorting, it is also impossible to detect unreasonable placement of the battery during transportation, thus leading to unreasonable placement of the battery. Summary of the Invention

[0003] In order to solve the above problems, the present invention proposes a pulling belt device for rapid cell type change positioning, which can not only adapt to different models of square batteries for transportation or assembly, but also perform appropriate detection and protection on the batteries during this process, improving the practical and safety performance of the device.

[0039] In some embodiments of the present invention, adjusting feet are provided at the bottom of the first support frame 201 to adjust the levelness of the first linear conveyor line 202.

[0040] In some embodiments of the present invention, the second linear conveyor line 302 includes a second linear conveyor frame 310, a second conveyor belt 320, and a second driving mechanism 330. A drag chain frame 311 is provided at the input end of the linear conveyor frame 310.

[0041] In some embodiments of the present invention, the second linear conveyor line 302 is a one-way transportation. A roller 340 for maintaining the tension of the second conveyor belt 320 is provided at the bottom of the second linear conveyor frame 310. The number and position of the rollers 340 are set according to the actual length of the second conveyor belt 320, and the distance between the rollers 340 is constant.

[0044] In some embodiments of the present invention, the battery sorting manipulator 102 includes a robotic arm 120 and jaws 130.

[0045] In some embodiments of the present invention, the robotic arm 120 includes a rotating base 121, a moving arm 122, and a driving device 123. The rotating base 121 is installed on the top of the bracket 101, and the rotating base 121 has a rotating part that can rotate around a vertical central axis. The driving device 123 is disposed on the rotating base 121, and the power output end of the driving device 123 is connected to the rotating part of the rotating base 121 for driving the rotating part to rotate around the vertical central axis of the rotating base 121. The moving arm 122 is disposed on the rotating base 121, with one end connected to the rotating part of the rotating base 121 and the other end installed with a gripper 130. The driving device 123 is not limited to being driven in a pneumatic or electric manner.

[0046] In some embodiments of the present invention, the rotation angle of the robotic arm 120 is 180° to 360°, and the gripper 130 is installed at the end of the robotic arm 120, facilitating the transfer of the battery on the first linear conveyor 202 to the corresponding second conveyor belt 320 of the second linear conveyor 302 disposed perpendicular to each other.

[0047] In some embodiments of the present invention, the gripper 130 further includes a first detection mechanism 140. The first detection mechanism 140 includes a first sensor mounting bracket 141 and a first sensor 142. The first sensor mounting bracket 141 is disposed on the side of the clamping block 1323, and the first sensor mounting bracket 141 is provided with an arc-shaped groove 1411. The first sensor is a laser distance measuring sensor and is installed on the arc-shaped groove 1411.

[0048] In some embodiments of the present invention, the arc-shaped groove 1411 is a 90° circular arc groove, and the first sensor 142 is movably installed on the arc-shaped groove 1411 and can rotate 90°, so as to perform positioning detection on the battery.

[0049] In some embodiments of the present invention, the light source ray angle of the first sensor 142 varies based on square lithium batteries of different lengths, measures and determines the arrival situation of the battery, and detects whether it is of the same length. If the length is too small, it cannot be detected, and the corresponding alarm unit is connected to remind the staff to replace the battery.

[0050] In some embodiments of the present invention, the clamping block 1323 is made of an insulating material, such as EPDM rubber, which can be used as a commonly used direct contact type insulating material in the production and transportation of lithium batteries. Its excellent corrosion resistance and heat resistance can face various battery abnormal situations.

[0051] In some embodiments of the present invention, there are four sets of the buffer connection components 150, which are respectively arranged at the four corners of the mounting base. The buffer connection components 150 include linear bearings 151, guide rods 152 and springs 153. The linear bearings 151 are fixedly inserted through the fixing plate 1321; the guide rods 152 are slidably inserted through the linear bearings 151.

The quality and test variation data among lithium batteries of the same specification level are similar. This design uses the quality comparison before and after the battery is clamped to help the staff further judge the specification differences of the battery. The increase in the battery weight will cause the deformation of the spring, thereby causing the installation position sensed by the sensor to drop. If the difference in the drop height is too large or too small, it will be detected and an alarm will be triggered to remind the staff to replace the battery.

[0052] In some embodiments of the present invention, the buffer connection component 150 further includes a second detection mechanism 160 for monitoring the clamping and transporting actions of the clamping jaws. The second detection mechanism 160 includes a second sensor mounting bracket 161 and a second sensor 162. The second sensor mounting bracket 161 is arranged on the side surface of the fixing plate 1321 and is provided with an induction piece at the top; the second sensor 162 is mounted on the side surface of the mounting base 131 and is spaced vertically opposite to the second sensor mounting bracket 161. The second sensor 162 is provided with a detection slot for the induction piece to be inserted. During use, the induction piece can move up and down under the pulling of the spring, and thus the depth of insertion into the detection slot can be adjusted, causing the light emitted by the second sensor 162 to change, thereby detecting the model information of the battery.

Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
