Description

Technical Field

[0001] The present invention relates to the field of detection equipment, and in particular to a new energy battery detection device and a method for using the same. Background Art

[0002] With the continuous development of new energy batteries, battery product quality testing is particularly important, especially when used in mobile vehicles. As a power source, new energy batteries need to have impact resistance, and during the impact process, the battery surface needs to have the ability to resist puncture. Therefore, puncture detection is a key link in battery testing.

[0003] Existing equipment for battery puncture detection all performs puncture by pressing down, that is, in an explosion-proof cabinet, after placing the battery in the detection position, the puncture mechanism is driven to press down by the pressing mechanism to perform puncture detection on the battery. When performing battery puncture detection, the puncture mechanism will replace different types of puncture needles according to different puncture detection requirements. When connecting the puncture needle, the existing puncture mechanism clamps one end of the puncture needle through an adjustable sleeve clamp, and then the puncture needle and the clamp synchronously follow the pressing mechanism to perform battery puncture. When replacing the puncture needle, the existing puncture mechanism relies on opening the sleeve clamp. The clamping groove of this clamp is squeezed on the outer wall of the puncture needle by the internal ball and spring, so as to squeeze and clamp the puncture needle. Therefore, the radius of the groove body that wraps the puncture needle will exceed the radius of the outer wall of the puncture needle. In this way, the clamping cooperation between the balls is required when clamping the puncture needle.

[0004] Since the puncture needle needs to be replaced by constantly opening and closing the sleeve clamp, the vertical clamping of the puncture needle cannot be guaranteed, which makes the detection data inaccurate. Moreover, since the puncture needle needs to be replaced by repeatedly opening and closing the sleeve clamp, such puncture needle replacement operation is also time-consuming and labor-intensive. In view of this, this solution proposes a new energy battery detection device and its use method to solve the above problems. Summary of the Invention

The placement support plate 5 is positioned at the bottom end of the detection chamber through the positioning bolt 501.

[0068] It should be noted that the threaded end of the positioning bolt 501 is exposed in the inspection chamber, and both ends of the placement support plate 5 are provided with a bayonet, which can be used to place the placement support plate 5 on the outer wall of multiple positioning bolts 501, and then use a nut to thread the placement support plate 5 from the top and the threaded end of the positioning bolt 501, so that the placement support plate 5 is squeezed and installed using the nut.

[0069] A pressing mechanism is provided on the top of the detection chamber and is used for reciprocating movement in the vertical direction;

[0070] Specifically, the pressing mechanism includes:

[0071] The pressing cylinder 6 is provided at the top of the detection chamber, and a pressing rod 601 is provided at the output end of the pressing cylinder 6;

[0072] The guide rod 7 is fixedly connected to the top of the detection chamber and is located on the side of the pressing cylinder 6. A connecting guide plate 8 is sleeved between the outer wall of the guide rod 7 and the outer wall of the pressing rod 601.

[0073] It should be noted that one end of the connecting guide plate 8 and the lower pressure rod 601 is a fixed sleeve, so that the connecting guide plate 8 and the lower pressure rod 601 move synchronously in the vertical direction, while the one end of the connecting guide plate 8 and the guide rod 7 is a sliding sleeve, so that under the support and restriction of the guide rod 7, the lower pressure rod 601 can slide stably in the vertical direction.

[0074] The puncture mechanism is arranged at the output end of the pressing mechanism. The puncture mechanism includes a bearing part, a puncture part and an adjusting part. The adjusting part is arranged in the bearing part, and the puncture part is arranged at the bottom of the adjusting part. The puncture position of the puncture part is adjusted by rotating the adjusting part after pressing down. The bearing part is fixed to the end of the pressing rod 601 away from the pressing cylinder 6.

[0075] Specifically, the bearing portion includes:

[0076] The upper carrying box 9 has a connecting sleeve 901 at the top thereof, and the connecting sleeve 901 is sleeved on the bottom of the lower pressing rod 601;

[0077] The lower carrier box 10 is arranged at the bottom end of the upper carrier box 9, a flange 11 is arranged between the lower carrier box 10 and the upper carrier box 9, the adjustment part is arranged between the lower carrier box 10 and the upper carrier box 9, and the puncture part is inserted and connected to the bottom end of the lower carrier box 10.

[0078] It should be noted that the top cross-sections of the upper carrier box 9 and the lower carrier box 10 are both circular, and the upper carrier box 9 is sealed at the top and open at the bottom, while the lower carrier box 10 is open at the top and semi-open at the bottom, that is, there is a ring plate blocking structure at the part of the bottom close to the outer ring wall, and two sets of flanges 11 are respectively fixedly connected to the outer wall of the bottom end of the upper carrier box 9 and the outer wall of the top end of the lower carrier box 10. When the upper carrier box 9 and the lower carrier box 10 are connected, bolts are passed through the two sets of flanges 11, so that a closed connection between the upper carrier box 9 and the lower carrier box 10 can be achieved;

[0079] A connecting sleeve 901 is welded and fixed on the top of the upper supporting box 9. The inner wall radius of the connecting sleeve 901 is the same as the outer wall radius of the bottom of the lower pressure rod 601. Therefore, after the connecting sleeve 901 is put on the bottom of the lower pressure rod 601, it is inserted and locked with screws, so that the lower pressure rod 601 and the upper supporting box 9 are detachably fixedly connected through the connecting sleeve 901.

[0080] Specifically, the adjustment department includes:

[0081] The carrying swivel 12 is rotatably inserted into the lower carrying box 10. The bottom end of the carrying swivel 12 is fixedly connected to the mounting block 1201. A supporting spring 13 is provided between the bottom end of the carrying swivel 12 and the bottom inner wall of the lower carrying box 10. The puncture portion includes a puncture needle 1202, which is threadedly inserted into the bottom end of the mounting block 1201. A plurality of arc-shaped blocks 1203 are provided on the top of the carrying swivel 12.

[0082] It should be noted that the outer wall radius of the carrying swivel 12 is the same as the inner wall radius of the lower carrying box 10, and the carrying swivel 12 can rotate and move vertically in the lower carrying box 10. The mounting block 1201 is a pancake-shaped structure, which is fixedly connected to the bottom end of the carrying swivel 12 and can be integrated with the carrying swivel 12 by welding. The outer wall radius of the mounting block 1201 is the same as the opening radius of the bottom of the lower carrying box 10, thereby ensuring that the mounting block 1201 can intersperse and slide vertically with the lower carrying box 10.

[0083] A plurality of threaded grooves are provided around the outer ring wall of the bottom end of the mounting block 1201, and one end of the puncture needle 1202 is spike-shaped, and the other end adopts a threaded structure, through which the threaded structure is threadedly matched with the threaded groove, so that multiple groups of puncture needles 1202 with different spike shapes are connected around the bottom end of the mounting block 1201.

[0084] The positioning sleeve 14 is sleeved on the inner wall of the upper carrier box 9. The bottom end of the positioning sleeve 14 is provided with a positioning slot 1401. The top of the arc-shaped card block 1203 is connected with the positioning slot 1401.

[0085] It should be noted that the positioning sleeve 14 is fixedly connected to the inner wall of the upper carrying box 9. Through the insertion of the positioning slot 1401 and the arc-shaped block 1203, the positioning sleeve 14 supports the structure at the carrying swivel 12 to move upward, thereby limiting the vertical upward movement of the carrying swivel 12, and the positioning slot 1401 and the arc-shaped block 1203 are inserted and connected close to the half of the outer ring wall of the carrying swivel 12.

[0086] The pressing sleeve 15 is inserted into the upper supporting box 9, and the pressing sleeve 15 is slidably inserted into the middle of the positioning sleeve 14. A pressing slot 1501 is provided at the bottom end of the pressing sleeve 15. The pressing sleeve 15 squeezes the supporting ring 12 through the inner wall of the pressing slot 1501 to rotate downward.

[0087] It should be noted that the pressing slot 1501 is a continuous wavy groove structure at the bottom end of the pressing sleeve 15, and the pressing slot 1501 and the arc-shaped block 1203 are interlaced and connected close to the half of the inner ring wall of the bearing swivel 12. Therefore, when the pressing sleeve 15 is pressed down, the inner wall of the pressing slot 1501 squeezes the arc-shaped block 1203 downward. At the same time, since the outer walls of the pressing slot 1501 and the arc-shaped block 1203 are both arc-shaped structures, Therefore, in the process of squeezing each other against the wall, the arc-shaped block 1203 will rotate when moving downward, and the rotation angle is half of the coverage range of the positioning slot 1401. When the downward pressure on the sleeve 15 is cancelled, the arc-shaped block 1203 is squeezed and interlaced with the positioning slot 1401. At this time, the arc-shaped block 1203 drives the carrying ring 12 to rotate, so that the arc-shaped block 1203 and the positioning slot 1401 are mounted against the wall.

[0088] Furthermore, a pressing block 16 is provided at the top of the pressing sleeve 15, and the pressing block 16 is connected to the middle part of the upper supporting box 9 in the vertical direction. A limiting groove 902 is provided on the inner wall of the insertion point between the upper supporting box 9 and the pressing block 16, and a limiting slider 1601 is fixedly connected to the outer wall of the pressing block 16, and the limiting slider 1601 is slidably inserted and connected in the limiting groove 902.

[0089] It should be noted that, with the sliding cooperation between the limiting slide groove 902 and the limiting slider 1601, the pressing sleeve 15 can slide stably in the vertical direction and ensure that the pressing sleeve 15 will not rotate, so that under the squeezing of the pressing sleeve 15, the arc-shaped block 1203 drives the supporting swivel 12 to rotate.

[0090] In a second embodiment, the present invention provides a method for using a new energy battery detection device. The method adopts the new energy battery detection device of the first embodiment, and includes the following steps:

[0091] The first step is to open the closing mechanism to expose the inspection chamber and check the various mechanisms inside the inspection chamber to ensure that the device can be operated;

[0092] It should be noted that the snap-fit ​​connection between the lock block 3 and the lock frame 4 is opened, and then the closed door 2 is opened to check the connection of the pressing mechanism.

[0093] The second step is to install and adjust the placement mechanism and place the battery pack to be tested on top of the placement mechanism;

[0094] It should be noted that the support plate 5 is positioned through the threaded cooperation between the nut and the positioning bolt 501, and then the new energy battery to be tested is placed on the top of the support plate 5, and the battery detection position needs to be aligned with the geometric center of the support plate 5.

[0095] The third step is to adjust the puncture mechanism. First, check the stability of the connection between the load-bearing part and the output end of the pressing mechanism. After ensuring the connection is stable, press the adjustment part to rotate the puncture part. Suspend the puncture site to be used directly above the center of the placement mechanism. At the same time, check that the puncture mechanism remains in a vertical position.

[0096] It should be noted that when it is necessary to adjust different puncture needles 1202, the pressing sleeve 15 is pressed in the vertical direction. At this time, the pressing slot 1501 squeezes the arc-shaped block 1203. When the pressing slot 1501 is squeezed to the bottom of the arc-shaped block 1203, the arc-shaped block 1203 moves down and is moved out by the inner wall of the positioning slot 1401. At this time, the pressing sleeve 15 continues to be pressed down. At this time, the pressing slot 1501 continues to squeeze the arc-shaped block 1203. When the arc-shaped block 1203 drives the carrying swivel 12 to move downward, it also drives the carrying swivel 12 to rotate. At this time, the mounting block 1201 and the puncture needle 1202 move downward and rotate synchronously, and when the carrying swivel 12 moves downward, it squeezes the supporting spring 13 to cause it to contract under force.

[0097] When the contact is pressed against the pressing sleeve 15, the arc-shaped block 1203 moves upward and cooperates with the inner wall of the positioning slot 1401 to squeeze and rotate the supporting ring 12. At this time, the supporting ring 12 ends its rotation and the adjustment of a set of puncture needles 1202 is completed.

[0098] By using the above method, different puncture needles 1202 can be adjusted to keep them above the detection position of the battery to be detected.

[0099] The fourth step is to close the sealing mechanism to ensure that the detection chamber is tightly sealed, and then start the explosion-proof cabinet 1. At this time, the pressing mechanism drives the puncture mechanism to press down and perform a downward puncture test on the battery placed on the top of the mechanism.

[0100] It should be noted that after the explosion-proof cabinet 1 is powered on, the downward pressure cylinder 6 drives the downward pressure rod 601 to move downward. At this time, under the guidance of the connecting guide plate 8 and the guide rod 7, the downward pressure rod 601 drives the puncture mechanism to move downward, so that the puncture needle 1202 squeezes and punctures the battery when moving downward.

[0101] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
