Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery detection, in particular to a device for detecting the height of terminals of automotive lithium batteries. Background Art

[0002] In the pure electric vehicle industry, lithium batteries are widely used due to their high energy density, long life and other characteristics. During the assembly process of lithium batteries, multiple lithium batteries need to be assembled into a housing to form a battery pack, and then the opposite terminals are connected to each other through connecting wires. Among them, the connecting wires are fixed to the electrode posts of the battery pack through the terminals. After the fixing is completed, the height of the terminals needs to be measured, mainly to prevent the high height caused by the terminals not being tightened from affecting subsequent assembly.

[0003] At present, the existing terminal measuring devices mainly use hard steel rulers or vernier calipers for measurement, and only single terminals can be measured one by one during measurement, which may affect the measurement efficiency of lithium battery terminals. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a device for detecting the height of terminals of automotive lithium batteries that can overcome or at least partially solve the above problems.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for detecting the height of terminals of automotive lithium batteries includes: a pressing plate, and further includes: a housing fixedly arranged on the pressing plate; a plurality of sliding rods hermetically and slidably arranged on the pressing plate, and the sliding rods are matched with the terminals of the lithium battery; a spring fixedly arranged between the sliding rod and the pressing plate; a detection tube arranged on the housing; and a plurality of scale lines equidistantly arranged on the outer side of the detection tube.

[0007] Furthermore, it further includes a measuring table for placing the lithium battery pack. The measuring table is symmetrically and fixedly connected with a first cylinder, and the output ends of the two first cylinders are both fixedly connected with the housing. A controller is fixedly connected to the measuring table.

[0008] Preferably, a plurality of filling blocks are fixedly connected to the pressing plate.

[0009] In order to facilitate the measurement of different lithium battery terminals, further, a transparent barrel is fixedly connected to the housing. The transparent barrel is coaxially arranged with the detection tube. A sealing plate is hermetically and slidably arranged in the transparent barrel. The detection tube is fixedly arranged on the sealing plate. A driving assembly for adjusting the lifting of the sealing plate is arranged on the housing.

[0010] Preferably, the driving assembly includes second cylinders symmetrically and fixedly connected to the housing. A connecting plate is fixedly connected between the output ends of the two second cylinders, and connecting rods are symmetrically and fixedly connected between the connecting plate and the sealing plate.

[0011] To prevent liquid from overflowing, further, a round hole is provided on the connecting plate, and a liquid level sensor matching the round hole is provided on the measuring table.

[0012] Compared with the prior art, the present utility model provides a device for detecting the height of automotive lithium battery terminals, having the following beneficial effects:

[0013] 1. For the device for detecting the height of automotive lithium battery terminals, by controlling the two first cylinders to extend a specified distance through the controller, the pressing plate is pressed on the outer shell of the battery pack. At this time, the lower ends of multiple sliding rods all contact the upper surface of the lithium battery terminals. And the terminals that are not fully tightened will protrude a certain distance. If there are terminals that are not tightened in the lithium battery battery pack to be measured, at this time, the protruding lithium battery terminals squeeze the sliding rods to move upward, squeezing the water in the housing. At this time, the water in the housing enters the detection tube. By observing the liquid level in the detection tube before and after measurement, it is judged whether there are lithium battery terminals that are not tightened in the area to be measured. If there are terminals that are not tightened, then further measure the terminals of each lithium battery, thereby effectively improving the efficiency of measuring the height of lithium battery terminals.

[0014] 2. For the device for detecting the height of automotive lithium battery terminals, the position of the sealing plate is adjusted by two second cylinders, thereby adjusting the liquid level in the detection tube, so that different lithium battery terminals can be measured.

[0015] 3. For the device for detecting the height of automotive lithium battery terminals, during the measurement process, the liquid level information in the detection tube is obtained in real time through the liquid level sensor. When the liquid level reaches the specified height and there are more terminals that are not tightened at this time, the controller controls the first cylinder to stop extending, thereby effectively preventing the water in the housing from overflowing from the detection tube.

[0016] The parts not involved in this device are the same as or can be implemented by the prior art. The present utility model effectively improves the efficiency of measuring the height of lithium battery terminals and can measure different lithium battery terminals.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Embodiment 1: Refer to Figures 1-4 , a device for detecting the height of automotive lithium battery terminals, including: a pressing plate 2, and further including: a housing 201, fixedly arranged on the pressing plate 2; a plurality of slide bars 202, hermetically and slidably arranged on the pressing plate 2, and the slide bars 202 are matched with the terminals of the lithium battery; a spring 203, fixedly arranged between the slide bars 202 and the pressing plate 2; a detection tube 306, arranged on the housing 201; a plurality of scale lines 307, equidistantly arranged on the outer side of the detection tube 306.

[0024] It further includes a measuring table 1 for placing the lithium battery pack. First cylinders 101 are symmetrically and fixedly connected to the measuring table 1. The output ends of the two first cylinders 101 are fixedly connected to the housing 201. A controller 102 is fixedly connected to the measuring table 1.

[0025] When batch measuring the terminal height on a lithium battery, place the lithium battery pack on the measuring table 1 and position it appropriately. Control the two first cylinders 101 to extend a specified distance through the controller 102 so that the pressing plate 2 presses on the battery pack housing. At this time, the lower ends of multiple sliding rods 202 are all in contact with the upper surface of the lithium battery terminals. And the terminals that are not fully tightened will protrude by a certain distance. If there are any un-tightened terminals in the lithium battery pack to be measured, the protruding lithium battery terminals will squeeze the sliding rods 202 to move upward, squeezing the water in the housing 201. At this time, the water in the housing 201 enters the detection tube 306. By observing the liquid level in the detection tube 306 before and after measurement, it is judged whether there are any un-tightened lithium battery terminals in the area to be measured. If there are un-tightened terminals, further measure the terminals of each lithium battery, thus effectively improving the efficiency of measuring the height of lithium battery terminals.

[0026] Embodiment 2: Refer to Figures 1-4 , a device for detecting the height of automotive lithium battery terminals, which is basically the same as Embodiment 1. Further, a plurality of filling blocks 204 are fixedly connected to the pressing plate 2.

[0027] By providing a plurality of filling blocks 204, where the filling blocks 204 are made of lightweight foam, the water injection volume in the housing 201 is effectively reduced.

[0028] A transparent barrel 3 is fixedly connected to the housing 201. The transparent barrel 3 is coaxially arranged with the detection tube 306. A sealing plate 304 is hermetically slidable in the transparent barrel 3. The detection tube 306 is fixedly arranged on the sealing plate 304. A driving component for adjusting the lifting of the sealing plate 304 is provided on the housing 201.

[0029] The driving component includes second cylinders 301 symmetrically and fixedly connected to the housing 201. A connecting plate 302 is fixedly connected between the output ends of the two second cylinders 301. Connecting rods 305 are symmetrically and fixedly connected between the connecting plate 302 and the sealing plate 304.

[0030] A round hole 303 is provided on the connecting plate 302. A liquid level sensor 103 matching the round hole 303 is provided on the measuring table 1.

[0031] When measuring the lithium battery terminals with different reserved heights between the battery pack housing and the battery terminals, adjust the position of the sealing plate 304 through the two second cylinders 301, thereby adjusting the liquid level in the detection tube 306, so that different lithium battery terminals can be measured.

[0032] During the measurement process, the liquid level sensor 103 is used to obtain the liquid level information in the detection tube 306 in real time. When the liquid level reaches the specified height and there are many untightened terminals at this time, the controller 102 controls the first cylinder 101 to stop extending, thereby effectively preventing the water in the housing 201 from overflowing from the detection tube 306.

[0033] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
