Description

Technical Field

[0001] This utility model relates to the field of new energy battery cell module assembly technology, and in particular to a precision positioning battery cell NG trolley. Background Technology

[0002] A battery cell is the basic component of a battery, typically encapsulated in a metal casing, and converts chemical energy into electrical energy through a chemical reaction. A battery cell consists of a positive electrode, a negative electrode, a separator, and an electrolyte. The positive and negative electrodes are separated by the separator, and the electrolyte helps maintain ion flow. The performance characteristics of a battery cell include capacity, voltage, cycle life, and safety, which directly affect the overall performance of the battery.

[0003] There are various types of battery cells, the most common being lithium-ion batteries, nickel-metal hydride batteries, and lead-acid batteries. Lithium-ion batteries are widely used in various electronic devices, such as mobile phones, laptops, and electric vehicles, due to their high energy density and long cycle life. Furthermore, battery cells come in various packaging structures, including cylindrical, prismatic, and pouch cells, each with its own unique advantages, disadvantages, and application scenarios.

[0004] In electric vehicles, the battery cell is the core component of the power battery, determining key performance indicators such as energy density, power performance, safety, and lifespan. Battery cells are connected in series and parallel to form battery modules, and multiple modules are then connected in series to form a battery pack, creating a combined unit that directly provides electrical energy. The battery pack also includes electrical connections, a cooling system, and insulation protection components to ensure overall performance and safety.

[0005] As production capacity increases, the demand for battery cells also grows. The stability of battery cells determines the yield of the production line. NG (Not Qualified) battery cells need to be removed from the line promptly during testing. If they are manually removed one by one, it severely impacts the finished product output. Therefore, NG battery cells need to be removed from the line by equipment. This places high demands on the precision of the NG cart, requiring a positioning accuracy of ±0.01mm. This ensures the timely removal of NG battery cells. Furthermore, the NG cart can control the position of battery cells by area, distinguishing NG types such as voltage NG, internal resistance NG, K-value NG, capacity NG, edge voltage NG, charge / discharge NG, etc. Summary of the Invention

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0037] First, combine Figures 1-3 This invention describes a precision positioning NG cell trolley according to an embodiment of the present invention, used for precision positioning of the NG trolley 100, and has a wide range of applications.

[0038] like Figures 1-3 As shown, an embodiment of the present invention provides a precision positioning battery cell NG trolley, comprising an NG trolley 100, a positioning mechanism, and multiple rows of photoelectric sensors 300.

[0039] Specifically, such as Figures 1-3 As shown, the top of the NG cart 100 is provided with multiple rows of fixing slots 101 for placing NG cells 400. The bottom of the NG cart 100 is provided with casters and the top is provided with a handle to facilitate the movement of the NG cart 100.

[0040] Specifically, such as Figures 1-3 As shown, the positioning mechanism is used to position and lock the NG cart 100. The positioning mechanism includes a positioning frame body 201 and a positioning assembly. The positioning assembly is used to lock and position the NG cart 100 on the positioning frame body 201. The positioning assembly includes a tilting cylinder 202, a clamping plate 203, and a clamped component (not shown in the figure). The tilting cylinder 202 is mounted on the positioning frame body 201, and its output end has a tilting component; the clamping plate 203 is mounted on the positioning frame body 201; and the clamped component is mounted on the NG cart 100. By controlling the rotation of the tilting component through the tilting cylinder 202, the clamped component can be locked between the tilting component and the clamping plate 203, thereby achieving the positioning and locking of the NG cart 100.

[0041] Specifically, such as Figures 1-3 As shown, multiple rows of photoelectric sensors 300 are mounted on the positioning mechanism. The number and position of the multiple rows of photoelectric sensors 300 correspond one-to-one with the number and position of the multiple rows of fixing slots 101, and are used to detect whether NG cells 400 are placed in the corresponding multiple fixing slots 101 respectively.

[0042] Furthermore, such as Figures 1-3 As shown, a precision positioning NG cell trolley according to an embodiment of the present invention further includes: a BASE board 102, the BASE board 102 is disposed on the top of the NG trolley 100, multiple rows of fixing slots 101 are formed on the BASE board 102, and each row of fixing slots 101 is provided with an elongated hole 103. A photoelectric sensor 300 detects whether there is an NG cell 400 on the fixing slot 101 through the corresponding elongated hole 103.

[0043] Furthermore, such as Figures 1-3 As shown, the positioning mechanism also includes a pair of guide frames 204, which are arranged on both sides of the outer end of the positioning frame body 201 to guide the NG trolley 100 into the positioning mechanism.

[0044] Furthermore, such as Figures 1-3 As shown, the positioning mechanism also includes: multiple guide wheels 205 and two guide plates 206. The multiple guide wheels 205 are arranged on both sides of the positioning frame body 201; the two guide plates 206 are arranged on both sides of the inside of the NG carriage 100. When the NG carriage 100 is pushed into the positioning mechanism, the guide wheels 205 roll on the corresponding guide plates 206, thereby providing internal guidance for the pushing of the NG carriage 100.

[0045] Furthermore, such as Figures 1-3As shown, the positioning mechanism also includes two buffers 207 and two buffer members 208. The two buffers 207 are disposed at the top end of the positioning frame body 201; the two buffer members 208 are disposed at the top end of the NG trolley 100. The two buffers 207 and the two buffer members 208 are used for cushioning when the trolley is pushed in.

[0046] Furthermore, such as Figures 1-3 As shown, the positioning mechanism also includes a pair of position detection sensors 209, which are disposed at the top end of the positioning frame body 201 and are used to detect whether the NG trolley 100 is in position.

[0047] Furthermore, such as Figures 1-3 As shown, the bottom of the positioning frame body 201 is provided with fixing feet 210 for fixing the positioning frame body 201 to a designated external ground.

[0048] Working principle:

[0049] 1. When the battery cell is 400NG (e.g., the voltage NG, internal resistance NG, K value NG, capacity NG, edge voltage NG, charge / discharge NG of battery cell 400), the robot places the part according to the set NG type. When the position on the NG cart 100 is full and is detected by the photoelectric sensor 300, a full material signal is sent. At the same time, the tilting cylinder 202 is opened, and a person comes to push the cart.

[0050] 2. After manually pushing out the full NG trolley 100, push the empty trolley to the corresponding position. The NG trolley 100 enters the positioning mechanism along the inner and outer guides. When the NG trolley 100 is pushed into place and detected by the position detection sensor 209, it indicates that the NG trolley 100 is in place. Then the tilting cylinder 202 runs and locks the NG trolley 100.

[0051] 3. The robot places the NG battery cells 400 one by one into the corresponding fixed slots 101. Whenever a battery cell 400 is placed into the corresponding fixed slot 101, the battery cell 400 detection photoelectric sensor 300 will detect the battery cell 400 and send the corresponding signal to the robot.

[0052] Above, refer to Figures 1-3 A precision positioning battery cell NG trolley according to an embodiment of the present invention is described, which has the following beneficial effects:

[0053] 1. The NG trolley 100 and the positioning mechanism adopt both internal and external guidance to ensure that the trolley is pushed to the corresponding position normally.

[0054] 2. After the trolley is in place, the cylinder locks and fixes the NG trolley 100, ensuring that the trolley's position will not be moved due to human error, ensuring the accuracy of loading and unloading the battery cell 400, and enabling the robot to accurately grab and discharge the battery cell 400 without damaging it.

[0055] 3. Installing the sensor that detects the presence or absence of battery cell 400 on the positioning mechanism greatly reduces costs, and the number of sensors will not increase with the increase in the number of vehicles.
