Description

Technical Field

[0001] This utility model relates to the field of lithium battery thickness detection technology, and in particular to a rapid lithium battery thickness detection device. Background Technology

[0002] Thickness testing of lithium batteries is one of the important steps to ensure battery quality and performance. During the production and quality control process, accurate measurement of battery thickness not only helps to ensure battery consistency and reliability, but also helps to identify problems that may affect battery safety and lifespan.

[0003] The existing announcement number CN211576141U, entitled "A Lithium Battery Pack Thickness Detection Device," includes a mounting frame. A placement plate is slidably engaged at the bottom of the inner cavity of the mounting frame. Multiple positioning holes are formed on the placement plate. Clamping blocks are installed between the top surface of the placement plate and the positioning holes. Sliding grooves are formed on the top of the inner walls of both sides of the mounting frame, and sliding blocks are slidably engaged within these grooves. Two fixing rods are fixedly installed between the outer walls of two adjacent sliding blocks. A mounting plate is slidably sleeved on the fixing rods, and a measuring rod is slidably engaged on the mounting plate. A ball bearing is rotatably engaged at the bottom end face of the measuring rod. A scale is provided on the outer wall of the measuring rod. According to the size of the lithium battery pack, the base plate is engaged with the positioning holes using cylindrical pins and diamond pins, achieving one-sided two-pin positioning. This allows for the positioning and fixing of lithium battery packs of different sizes, facilitating detection with the top surface of the base plate as a reference.

[0004] However, when testing the thickness of the lithium battery pack, it is necessary to first fix the lithium battery pack on the placement plate, and then push the placement plate to carry the lithium battery pack to the mounting frame for testing. This testing method requires manual disassembly and assembly of the lithium battery pack on the placement plate. The disassembly and assembly process is cumbersome and not conducive to quickly completing the height testing of multiple lithium battery packs, which affects the efficiency of the height testing of multiple lithium battery packs. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a rapid lithium battery thickness detection device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a lithium battery thickness rapid detection device, comprising a transport component, a detection component, and a warning component. The transport component includes a transport frame, on which a belt roller is horizontally rotatably connected, and a transport belt is tensioned and installed on the belt roller. A transport motor is horizontally fixed at one end of the transport frame, and the output end of the transport motor is fixed on the belt roller shaft. Perforated plates are horizontally fixed on both sides of the transport frame. The detection component includes a rod, which is vertically slidably assembled on the perforated plate, and a warning component is vertically fixed on the bottom surface of the rod. The first spring has its top end fixed to the perforated plate. The top of the rod frame has a horizontally fixed perforated plate, and a perforated plate rotating frame is vertically slidably assembled below the perforated plate. A pressure roller is horizontally fixed on the bottom surface of the perforated plate rotating frame. The warning component includes a sliding frame, which is vertically fixed to the top surface of the perforated plate. A slider is vertically slidably assembled in the sliding frame. A power connector is vertically mounted through the slider. A warning light is vertically electrically connected to the top surface of the power connector. A terminal block is vertically assembled on the top surface of the rod frame, and a top post is vertically fixed to the top of the terminal block. The top post is plugged into the power connector.

[0007] As a preferred embodiment, a rubber post is vertically fixed on the top surface of the pole, and the top of the rubber post is vertically assembled and connected to the bottom of the terminal post.

[0008] As a preferred embodiment, a sleeve is horizontally fixed on the top surface of the slotted plate, and positioning rods are horizontally slidably inserted into both ends of the sleeve.

[0009] As a preferred embodiment, perforated strips are vertically fixed on both sides of the top surface of the perforated plate rotating frame, and the perforated strips of the perforated plate rotating frame are slidably connected in the perforated slot plate.

[0010] As a preferred embodiment, a second spring is sleeved on the positioning rod, and the two ends of the second spring are respectively fixed to the end of the positioning rod and the end of the sleeve.

[0011] As a preferred embodiment, multiple scale lines are horizontally opened on one side of the slide frame along the vertical direction, and an adjusting screw is assembled through the vertical thread on the top surface of the slide frame, with the bottom end of the adjusting screw rotatably connected to the top surface of the slider.

[0012] As a preferred option, the bottom surface of the transport frame is fixed and assembled using fixing screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: First, based on the required height of the lithium battery to be tested, the vertical movement height of the junction box in the sliding frame is adjusted to meet the height requirements of the lithium battery to be tested. The terminals and junction box are electrically connected to the external power supply line. The lithium battery pack to be tested is placed on the conveyor belt of the transport component. The transport motor is started to drive the conveyor belt, which in turn drives the lithium battery pack. As the lithium battery pack moves, the pressure roller is raised, pushing the perforated plate frame upwards and pulling the lifting rod frame vertically upwards on the perforated plate. Then, the rod frame pulls the first spring to deform, causing the top column on the top surface of the rod frame to move upwards. When a non-standard lithium battery pack is encountered during testing, the upward movement of the top column on the top surface of the rod frame increases, allowing the top column to insert into the junction box, thereby powering the warning light and issuing a warning for timely handling by the testing personnel. Simultaneously, large batches of lithium battery packs can be transported one by one to the testing component for testing, facilitating the rapid completion of height testing for multiple lithium battery packs, thus improving the efficiency of height testing for multiple lithium battery packs.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0026] like Figures 1 to 5As shown, a rapid lithium battery thickness detection device includes a transport component 1, a detection component 2, and a warning component 3. The transport component 1 includes a transport frame 11, on which a belt roller is horizontally rotatably connected, and a transport belt 12 is tensioned and installed on the belt roller. A transport motor 15 is horizontally fixed at one end of the transport frame 11, and the output end of the transport motor 15 is fixed on the belt roller shaft. Perforated plates 13 are horizontally fixed on both sides of the transport frame 11. The detection component 2 includes a rod 21, which is vertically slidably assembled on the perforated plate 13. A first spring 22 is vertically fixed on the bottom surface of the rod 21, and the top end of the first spring 22 is fixed to the perforated plate. On the top of the pole frame 21, a slotted plate 23 is horizontally fixed, and a rotating frame 24 is vertically slidably assembled below the slotted plate 23. A pressure roller 25 is horizontally fixed on the bottom surface of the rotating frame 24. The warning element 3 includes a sliding frame 31, which is vertically fixed on the top surface of the slotted plate 13. A slider 32 is vertically slidably assembled in the sliding frame 31. A power connector 33 is vertically mounted through the slider 32. A warning light 34 is vertically electrically connected to the top surface of the power connector 33. A terminal 27 is vertically assembled on the top surface of the pole frame 21, and a top post 28 is vertically fixed to the top of the terminal 27. The top post 28 is inserted into the power connector 33. A rubber column 26 is vertically fixed on the top surface of the frame 21, and the top of the rubber column 26 is vertically assembled and connected to the bottom of the terminal block 27. The bottom surface of the transport frame 11 is fixed and assembled by fixing screws 14. In use, first, according to the height requirement of the lithium battery to be tested, adjust the vertical movement height of the power connector 33 in the slide frame 31 to meet the height requirement of the lithium battery to be tested. Connect the terminal block 27 and the power connector 33 to the external power supply line. Place the lithium battery pack to be tested on the transport belt 12 of the transport component 1. Start the transport motor 15 to drive the transport belt 12 to run, and drive the lithium battery pack to run. When the lithium battery pack is running, the pressure roller 2 is raised. 5. Push the perforated plate rotating frame 24 upward and pull the lifting rod 21 vertically upward on the perforated plate 13. Then, the rod 21 pulls the first spring 22 to deform, and the top column 28 on the top surface of the rod 21 moves upward. When encountering non-standard lithium battery packs during testing, the upward movement of the top column 28 on the top surface of the rod 21 increases, so that the top column 28 is inserted into the power receiving cup 33, thereby supplying power to the warning light 34 and issuing a warning to facilitate timely handling by the testing personnel. At the same time, a large batch of lithium battery packs are transported one by one to the testing piece 2 using the transport component 1 for testing, which facilitates the rapid completion of the height testing of multiple lithium battery packs, thus improving the efficiency of the height testing of multiple lithium battery packs.

[0027] In one embodiment, such as Figure 4 and Figure 5As shown, a sleeve 231 is horizontally fixed on the top surface of the slotted plate 23, and positioning rods 232 are horizontally slidably inserted into both ends of the sleeve 231. Perforated strips are vertically fixed on both sides of the top surface of the perforated plate rotating frame 24, and the perforated strips of the perforated plate rotating frame 24 are slidably connected in the slotted plate 23. A second spring 233 is sleeved on the positioning rod 232, and the two ends of the second spring 233 are respectively fixed to the end of the positioning rod 232 and the end of the sleeve 231. In order to meet the requirements of rapid lithium battery thickness detection, the vertically adjustable perforated plate rotating frame 24 is installed on the slotted plate 23. When adjusting the spacing on the slot plate 23, the positioning rod 232 is pulled and slid horizontally in the sleeve 231, compressing the second spring 233 to deform. The positioning rod 232 is pulled out of the hole strip of the perforated plate rotating frame 24, and then the perforated plate rotating frame 24 is pulled vertically in the slot plate 23 to adjust the spacing of the perforated plate rotating frame 24 installed on the slot plate 23. Then, the positioning rod 232 is released, and under the deformation force of the second spring 233, the positioning rod 232 is pushed into the hole strip of the perforated plate rotating frame 24, limiting and ensuring the spacing of the perforated plate rotating frame 24 installed on the slot plate 23.

[0028] In one embodiment, such as Figure 5 As shown, multiple scale lines 311 are horizontally opened on one side of the slide frame 31 along the vertical direction, and an adjusting screw 35 is vertically threaded through the top surface of the slide frame 31. The bottom end of the adjusting screw 35 is rotatably connected to the top surface of the slider 32. In use, firstly, according to the space required for the height of the lithium battery to be tested, the adjusting screw 35 is rotated to push the slider 32 to move vertically in the slide frame 31. According to the scale lines 311 on the outside of the slide frame 31, the vertical movement height of the power receiving cup 33 in the slide frame 31 is adjusted to meet the height requirements of the lithium battery to be tested.

[0029] In this embodiment, the process begins by rotating the adjusting screw 35 to push the slider 32 vertically within the slide frame 31, based on the required height of the lithium battery to be tested. The vertical movement height of the power connector 33 within the slide frame 31 is adjusted according to the scale lines 311 on the outer side of the slide frame 31 to meet the required lithium battery height. The terminal 27 and the power connector 33 are then electrically connected to the external power supply line. The lithium battery pack to be tested is placed on the transport belt 12 of the transport component 1, and the transport motor is started. 15 drives the conveyor belt 12 to run, which in turn drives the lithium battery pack. When the lithium battery pack is running, the pressure roller 25 is raised, which pushes the perforated plate rotating frame 24 to move upward and pulls the rod frame 21 to move vertically upward on the perforated plate 13. Then the rod frame 21 pulls the first spring 22 to deform, and the top column 28 on the top surface of the rod frame 21 moves upward. When a non-compliant lithium battery pack is encountered during testing, the upward movement of the top column 28 on the top surface of the rod frame 21 increases, so that the top column 28 is inserted into the power receiving cup 33, thereby supplying power to the warning light 34 and issuing a warning so that the testing personnel can deal with it in a timely manner.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
