Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a battery production batching weighing device which is convenient for adjusting weights. Background Art

[0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Lithium batteries need to be tested for various aspects of performance after production, and weight testing requires the use of a weight detection device.

[0003] When it is necessary to weigh the ingredients for battery production, they are generally weighed by weights on a weighing device. For example, a lithium battery production detection device with publication number CN211978054U includes a fixed seat, both ends of the top outer wall of the fixed seat are fixedly connected to support frames, and the top outer walls of the two support frames are fixedly connected to weighing sensors, the top outer wall of the fixed seat is fixedly connected to a support column, and both ends of the top outer wall of the support column are fixedly connected to a fixed plate, and the outer walls of the opposite sides of the two fixed plates are connected to the same connecting shaft through a bearing.

[0004] This weighing device places the battery in the weight frame and the item frame, and then the battery raw materials and weights are judged as the connecting rod tilts. However, during the tilting of the connecting rod, the raw materials themselves are easily spilled and lost due to the tilted connecting rod. At the same time, if the required weight is too heavy, several weights will be stacked and fixed in a limited space. The stacked weights will tilt with the connecting rod, and their own height will be too high, which will bring additional torque to the connecting rod, causing errors in the balance of both ends of the connecting rod. This affects the accuracy of the raw materials for battery production and is inconvenient to add weights later. Summary of the invention

[0032] The center of the top surface of the mounting plate 13 is provided with a detection structure 3, and two setting plates 31 of the detection structure 3 are fixedly connected to the top surface of the mounting plate 13. The two mounting plates 13 are arranged along the vertical direction, and the two mounting plates 13 are parallel to each other and have a gap. Transmission grooves 32 are provided on the surfaces of the two mounting plates 13, and a detection rod 33 is rotatably provided in the gap between the mounting plates 13 on both sides. Transmission shafts 34 are fixedly provided on the two sides of the detection rod 33 close to the mounting plate 13, and the transmission shaft 34 extends into the transmission transmission groove 32 for transmission connection, so that the detection rod 33 can rotate in the gap of the setting plate 31 through the transmission shaft 34. Rotating shafts 35 are rotatably provided at both ends of the detection rod 33, and rotating blocks 36 are fixedly connected to the surface of the rotating shaft 35. Adsorption magnets 37 are fixedly connected to the side of the rotating blocks 36 close to the fixed box 21 on both sides, and the adsorption magnets 37 are mutually adsorbed with the side close to the nearest permanent magnet.

[0033] A weight structure 4 is provided on the top surface of one of the placement plates 23, and a fixed weight 41 of the weight structure 4 is fixedly connected to the top surface of the placement plate 23. The fixed weight 41 is located at the center of the top surface of the placement plate 23, and a vertical rod 43 is fixedly connected to the center of the top surface of the fixed weight 41, and a clamping plate 44 is fixedly connected to the top of the vertical rod 43. A plurality of disassembly weights 42 are detachably provided on the top of the fixed weight 41, and the top surface of the disassembly weight 42 is provided with a vertical rod 43 and a clamping plate 44 that are the same as the top surface of the fixed weight 41.

The superposition height of the vertical groove 45 and the horizontal groove 46 is the same as the superposition height of the vertical rod 43 and the engaging plate 44 .

[0034] When using this battery production ingredient weighing device that is easy to adjust the weight, the battery production ingredients to be weighed are placed on the top surface of the placement plate 23 with an empty top surface. At this time, the placement plate 23 and the sliding column 22 slide downward under the gravity of the battery production ingredients above, and the buffer spring 25 at the bottom of the sliding column 22 buffers the sliding column 22 to prevent the buffer column from descending too quickly and causing the battery production ingredients to spill. After the force on the placement plate on the top surface of the sliding column 22 and the force on the buffer spring 25 are balanced, the sliding column 22 stops at the specified position. The sliding column 22 drives the connecting block 27 to move and change its height, so that the connecting block 27 drives the permanent magnet 28 to slide in the limit groove 26. The disassembly weight 42 is superimposed on the top surface of the fixed weight 41, thereby changing the force on the sliding column 22 below, so that the sliding column 22 on the other side drives the connecting block 27 and the permanent magnet 28 to move to a certain height for fixing. During the sliding process of the permanent magnets 28 on both sides, the permanent magnets 28 adsorb the adsorption magnets 37 in the air, so that the adsorption magnets 37 drive the detection rod 33 to rotate. The transmission shaft 34 on the surface of the detection rod 33 slides in the transmission groove 32, and the detection rod 33 adjusts the height of both sides through the transmission shaft 34, so that the detection rod 33 is driven to move during the movement of the permanent magnets 28. The rotating blocks 36 are rotatably arranged at both ends of the detection rod 33, so that the adsorption magnets 37 arranged on one side of the rotating block 36 are always opposite to the permanent magnets 28, so that the mutual magnetic force between them is at the maximum. The buffer spring 25 on the bottom surface of the sliding column 22 buffers and decelerates the descending speed of the sliding column 22, and can also prevent the permanent magnets 28 and the adsorption magnets 37 from separating from each other at too fast a speed. At this time, observe the current position of the detection rod 33. When the detection rod 33 is not in a horizontal position, the connection blocks 27 on both sides of the surface are not at the same height, and the battery production raw materials and weights on the top surface of the trays 23 on both sides are different in weight, the weights are added or removed until the detection rod 33 is in a horizontal position. At this moment, the connecting blocks 27 on both sides are at the same height, and the raw materials and weights on the top surfaces of the plates 23 on both sides are the same weight, and the weight reading is the weight of the raw materials for the battery. The fixed weight 41 and the disassembly weight 42 can be quickly disassembled and assembled. The vertical rod 43 and the engaging plate 44 are pinched to make the disassembly weight 42 suspended. The disassembly weight 42 is located on the side above the fixed weight 41, so that the vertical groove 45 and the horizontal groove 46 of the disassembly weight 42 are directly opposite to the vertical rod 43 and the engaging plate 44 on the top surface of the fixed weight 41. Then the engaging plate 44 extends into the horizontal groove 46 for engagement, and the vertical rod 43 extends into the vertical groove 45 for positioning. When the disassembly weight 42 moves to the top of the fixed weight 41, the vertical rod 43 and the engaging plate 44 on the top surface of the disassembly weight 42 are loosened, so that the disassembly weight 42 is placed on the top surface of the fixed weight 41. Repeating the above steps can stack the disassembly weight 42 on the top surface of the disassembly weight 42 for installation. When removal is required, the vertical rod 43 and the engaging plate 44 of the uppermost removal weight 42 are lifted, and the lower removal weight 42 slides downward in the transverse groove 46 , and the transverse groove 46 lifts the lower removal weight 42 in mid-air.Then, the disassembly weight 42 above the fixed weight 41 is slid to release the connection, and all the disassembly weights 42 can be removed by lifting the uppermost disassembly weight 42 .

[0035] Working principle of the present invention: The present invention is a battery production ingredient weighing device that is easy to adjust the weight. By setting a weighing structure 2 and a detection structure 3, the sliding column 22 is subjected to the gravity of the battery production raw materials and weights above, driving the connecting block 27 and the permanent magnet 28 to move. The permanent magnets 28 on both sides can adsorb the adsorption magnets 37, thereby driving the detection rod 33 to rotate; by observing whether the detection rod 33 is in a horizontal state, it can be judged whether the weights of the items on both sides are the same; the bottom buffer spring 25 can buffer and decelerate the movement of the sliding column 22, preventing the battery raw materials from splashing out from above, and also preventing the permanent magnet 28 and the adsorption magnet 37 from separating; the transmission shaft 34 of the detection structure 3 can slide in the transmission slot 32 to adapt to the permanent magnets 28 of different heights on both sides. A weight structure 4 is provided, the weight structure 4 is located on the top surface of the placement plate 23, the fixed weight 41 of the weight structure 4 is located at the center of the top surface of the placement plate 23, and the disassembly weight 42 is continuously stacked on the top surface of the fixed weight 41. The weight structure 4 as a whole presses the center of the sliding column 22 to balance the force on the sliding column 22, thereby avoiding uneven pressure of the top surface weight on the sliding column 22, thereby providing force to other places and causing inaccurate displacement, thereby affecting the accuracy of weighing raw materials for battery production.
