Description

Technical Field

[0001] This utility model relates to a size detection device, specifically a lithium battery casing size detection device. Background Technology

[0002] Lithium batteries are batteries that use metallic lithium or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. They are divided into lithium metal batteries (non-rechargeable) and lithium-ion batteries (rechargeable). The core difference between the two lies in whether they contain metallic lithium and whether they support cyclic charging and discharging.

[0003] The lithium battery casing is an important component of lithium-ion batteries, primarily serving to fix and completely seal the internal electrochemical system. Based on different packaging technologies, lithium battery casings can be divided into two types: rigid casing and flexible casing. Each type can be further classified into three shapes: cylindrical, square, and pouch.

[0004] The most common type of lithium battery on the market is square, which means that the size of the lithium battery needs to be measured, and a testing device is usually needed for the measurement.

[0005] Most existing testing instruments use automated measurement, which has limitations such as high complexity and cumbersome operation, and also has certain limitations in clamping lithium battery casings. Summary of the Invention

[0006] The purpose of this invention is to provide a lithium battery casing size detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A lithium battery casing size detection device includes a detection frame, and a synchronous clamping mechanism is provided on the top of the detection frame;

[0009] The synchronous clamping mechanism includes a baffle and a clamping plate, which operate relative to or away from each other to clamp the lithium battery casing.

[0010] A flexible pushing mechanism is also provided on one side of the clamping plate, and a laser rangefinder is provided on one side of the clamping plate. The laser rangefinder is used for distance measurement. The flexible pushing mechanism includes a switch, which is used to turn on the laser rangefinder so that the laser rangefinder can emit a laser beam to measure the distance.

[0011] The top of the testing frame is provided with a column, and the top of the column is provided with a shelf plate.

[0012] The lithium battery casing size detection device described above: a cylinder is provided on the top of the detection frame, and the output shaft of the cylinder is connected to a synchronous clamping mechanism. The synchronous clamping mechanism further includes a first rack, a gear, and a second rack. The first rack and the second rack are slidably disposed on the detection frame, and both the first rack and the second rack mesh with the gear. The gear is rotatably connected to the column through a bearing.

[0013] The lithium battery casing size detection device described above: a slide rail is provided on the top of the detection frame, and a slider is slidably disposed on the slide rail. The top of the slider is connected to both the first rack and the second rack.

[0014] The lithium battery casing size detection device described above: the baffle is disposed on the second rack, and the clamping plate is elastically disposed on the first rack.

[0015] The lithium battery casing size detection device described above: a round rod is provided on one side of the clamping plate, a spring is sleeved on the round rod, and one end of the round rod is connected to a switch to push the switch to turn on the laser rangefinder.

[0016] The lithium battery casing size detection device described above: a guide ring is provided at the top of the first rack, the guide ring is sleeved around the switch, and the switch is slidably connected to the guide ring.

[0017] The lithium battery casing size detection device described above has a guide groove on the clamping plate and a guide post that is slidably arranged thereon, with one end of the guide post being fixedly connected to the guide ring.

[0018] The lithium battery casing size detection device described above: the guide post is set at a height higher than the top of the lithium battery casing, and the position of the guide post can be adjusted according to the height of different types of lithium battery casings.

[0019] Compared with the prior art, the beneficial effects of this utility model are: by setting up a synchronous clamping mechanism and using the principle of a laser rangefinder, this utility model facilitates the synchronous clamping of the lithium battery casing before measurement, thereby improving the accuracy of the measurement data.

[0020] This utility model also sets the switch of the laser rangefinder as an elastic switch. When the lithium battery casing is uneven, the casing will first squeeze the clamping plate, and the clamping plate will move to one side of the guide ring. At the same time, it will squeeze the spring. Utilizing the spring's reset action, the clamping plate will fit tightly with the lithium battery casing, thereby further improving the accuracy of the laser rangefinder's emission position and the actual size of the lithium battery, and thus further improving the measurement accuracy.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-6 As an embodiment of the present utility model, the lithium battery casing size detection device includes a detection frame 1, and a synchronous clamping mechanism is provided on the top of the detection frame 1.

[0030] The synchronous clamping mechanism includes a baffle 8 and a clamping plate 9, which operate relative to each other or in opposite directions to clamp the lithium battery casing.

[0031] A flexible pushing mechanism is also provided on one side of the clamping plate 9, and a laser rangefinder 12 is provided on one side of the clamping plate 9. The laser rangefinder 12 is used for distance measurement. The flexible pushing mechanism includes a switch 13, which is used to turn on the laser rangefinder 12 so that the laser rangefinder 12 can emit a laser beam to measure the distance.

[0032] The top of the testing frame 1 is provided with a column 16, and the top of the column 16 is provided with a frame plate 17.

[0033] In this embodiment, a synchronous clamping mechanism is installed on the top of the testing frame 1. The lithium battery casing can be clamped by the synchronous clamping mechanism, and then the laser rangefinder 12 is used to measure the size.

[0034] Initially, the lithium battery casing is placed onto the support plate 17. By activating the synchronous clamping mechanism, the baffle 8 and clamping plate 9 operate synchronously, clamping the lithium battery casing at both ends. When one side of the baffle 8 blocks one side of the lithium battery casing, the other side of the clamping plate 9 will also block the other side of the lithium battery casing simultaneously. This ensures that the inner diameter of the lithium battery casing is between the baffle 8 and the clamping plate 9. The laser rangefinder 12 on one side of the clamping plate 9 emits a laser beam that can be projected onto the surface of the baffle 8. Based on the principle of the laser rangefinder 12, the distance between the laser rangefinder 12 emission point and the baffle 8 is the size of the lithium battery casing, thus completing the measurement.

[0035] As a further embodiment of this utility model, a cylinder 2 is provided on the top of the testing frame 1. The output shaft of the cylinder 2 is connected to a synchronous clamping mechanism. The synchronous clamping mechanism further includes a first rack 3, a gear 4, and a second rack 5. The first rack 3 and the second rack 5 are slidably disposed on the testing frame 1. Both the first rack 3 and the second rack 5 mesh with the gear 4. The gear 4 is rotatably connected to the column 16 through a bearing.

[0036] In this embodiment, when the output shaft of cylinder 2 is pushed outward, the first rack 3 will move to the side opposite to cylinder 2, and the first rack 3 will drive the gear 4 to rotate. Since the gear 4 and the second rack 5 are also meshed on the other side, the second rack 5 will move synchronously in the opposite direction relative to the first rack 3. Therefore, the first rack 3 and the second rack 5 will move in opposite directions synchronously, widening the distance between the baffle 8 and the clamping plate 9, making it easier to put the lithium battery case in.

[0037] Since the center of gear 4 is connected to column 16 via a bearing, it does not affect the rotation of gear 4.

[0038] With the set synchronous clamping mechanism, synchronous relative and opposite operation can be achieved through a simple mechanical structure.

[0039] As a further embodiment of this utility model, the top of the detection frame 1 is provided with a slide rail 6, and a slider 7 is slidably disposed on the slide rail 6. The top of the slider 7 is connected to both the first rack 3 and the second rack 5.

[0040] In this embodiment, a slider 7 is installed at the bottom of both the first rack 3 and the second rack 5, and the slider 7 slides on the slide rail 6. By setting the slide rail 6 and the slider 7 at the bottom of the first rack 3 and the second rack 5 to cooperate in operation, the first rack 3 and the second rack 5 can run more stably.

[0041] As a further embodiment of this utility model, the baffle 8 is disposed on the second rack 5, and the clamping plate 9 is elastically disposed on the first rack 3.

[0042] In this embodiment, the second rack 5 drives the baffle 8 to run when it runs. Similarly, the first rack 3 drives the clamping plate 9 to run when it runs, so that the distance between the baffle 8 and the clamping plate 9 can be reduced or increased. This allows the distance between the two to be adapted to the lithium battery casing of different sizes, and also allows the dimensions of different surfaces of the lithium battery casing to be measured.

[0043] As a further embodiment of this utility model, a round rod 10 is provided on one side of the clamping plate 9, and a spring 11 is sleeved on the round rod 10. One end of the round rod 10 is connected to the switch 13 so as to push the switch 13 to open the laser rangefinder 12.

[0044] In this embodiment, a round rod 10 is installed on one side of the clamping plate 9. One end of the round rod 10 is configured to push the switch 13. Since the surface of the lithium battery casing may be uneven, the switch 13 is made elastic. When the clamping plate 9 blocks the uneven part of the lithium battery casing, it will squeeze the clamping plate 9. The clamping plate 9 will squeeze one end of the round rod 10, which will also squeeze the spring 11. Both the clamping plate 9 and the round rod 10 will squeeze one side of the switch 13, thereby opening the switch 13, which means turning on the laser rangefinder 12.

[0045] As a further embodiment of this utility model, a guide ring 14 is provided at the top of the first rack 3, the guide ring 14 is sleeved around the switch 13, and the switch 13 is slidably connected to the guide ring 14.

[0046] In this embodiment, from Figure 3 As can be seen, there is a certain distance between the guide ring 14 and the clamping plate 9 on one side. When the switch 13 is turned on, the clamping plate 9 will reduce the distance between itself and the guide ring 14.

[0047] As a further embodiment of this utility model, the clamping plate 9 is provided with a guide groove and a guide post 15 is slidably provided thereon, one end of the guide post 15 being fixedly connected to the guide ring 14.

[0048] Meanwhile, a circular groove is also provided on the clamping plate 9 to prevent the laser beam emitted by the laser rangefinder 12 from being blocked.

[0049] In this embodiment, a guide groove is provided on the clamping plate 9, and a guide post 15 is connected to one side of the guide ring 14. The guide post 15 is to make the clamping plate 9 more stable when running towards the guide ring 14.

[0050] As a further embodiment of this invention, the guide post 15 is set at a height higher than the top of the lithium battery casing, and the position of the guide post 15 can be adjusted by the height of different types of lithium battery casings.

[0051] In this embodiment, the height of the guide post 15 on the clamping plate 9 is designed to be adjustable because there are many different types and sizes of lithium battery casings. Therefore, the height of the guide post 15 on the clamping plate 9 needs to be designed to be adjustable so as not to affect the measurement of the size of the lithium battery casing.

[0052] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
