Description

Technical Field

[0001] This utility model relates to the field of battery gas detection equipment technology, specifically to a novel suction gun device and suction gun system. Background Technology

[0002] A helium suction gun detector is a specialized device that uses helium as a tracer gas, combined with mass spectrometry or thermal conductivity sensor technology, to perform high-precision leak detection in sealed systems. Its core principle is to collect gas near suspected leak points using a suction gun, quickly analyze the helium concentration within the gas, and thus locate and quantify the amount of leakage.

[0003] However, when the suction gun helium detector is used to detect leaks in battery packs, uneven surfaces at the detection points on the battery pack or low precision in controlling the movement of the suction gun can cause excessive impact loads when the suction gun collides with the object being tested. This can damage the detection tube or cause the entire device to be destroyed due to the impact force being transmitted to the suction gun. This can affect the use of the suction gun helium detector. Utility Model Content

[0004] The first aspect of this utility model aims to solve the technical problem that excessive impact load caused by the collision between the suction gun and the object to be tested can damage the gas detection tube or cause the overall device to be destroyed due to the transmission of the collision force to the suction gun. The present invention provides a novel suction gun device that can buffer the collision force between the gas detection tube and the detection position by setting a buffer component, thereby preventing the continuous transmission of the collision force to the main body of the suction gun device.

[0005] To achieve the above objectives, this utility model provides a novel suction gun device, including an air tube assembly, a mounting frame, and a motion assembly. The mounting frame includes a first mounting plate, a second mounting plate, and a buffer assembly. The first mounting plate is positioned above the second mounting plate, the buffer assembly is positioned between the first and second mounting plates, the motion assembly is connected to the first mounting plate, and the air tube assembly is mounted on the second mounting plate. The motion module adjusts the position of the air tube assembly relative to the test location, facilitating the air tube assembly's proximity to the test location for helium absorption and leakage detection. During dynamic testing, the motion module first moves the air tube assembly to a position close to the test part, then sequentially scans each test location along a predetermined route to check for leaks. When the air tube assembly collides with the test object under the driving action of the motion assembly, the buffer assembly buffers the impact load, preventing damage to the air tube assembly and the suction gun device.

[0006] Preferably, the buffer assembly includes multiple guide posts and linear bearings. The guide posts are positioned at the edges of the first and second mounting plates. The first mounting plate has guide holes, and the linear bearings are installed within the guide holes. The upper ends of the guide posts are slidably connected to the linear bearings, and the bottoms of the guide posts are connected to the second mounting plate. The sliding cooperation between the linear bearings and the guide posts ensures precise guidance and stable movement of the second mounting plate and its connected air tubing assembly. Upon impact, the second mounting plate receives an upward impact load and moves along the axial direction of the guide posts, preventing misalignment and slippage of the second mounting plate and its installed air tubing assembly due to force displacement. This ensures a smooth buffering process without generating additional lateral destructive forces.

[0007] Preferably, the buffer assembly further includes an elastic element sleeved on the outer wall of the guide post, with its two ends abutting against the opposing surfaces between the first and second mounting plates, respectively. When the air tube assembly collides, the spring is compressed or stretched, converting the instantaneous impact force into the elastic potential energy of the spring, significantly weakening the impact force and avoiding damage caused by hard contact. Simultaneously, after the collision, the spring can drive the detection head to reset, without affecting subsequent detection.

[0008] Preferably, the gas tube assembly includes a gas detection tube and a gas clearing tube. The gas detection tube is used to absorb gas at the detection location before detection, and the gas clearing tube is used to absorb excess gas before the gas detection tube is used; and / or, the bottom of the gas detection tube and the gas clearing tube has an arc-shaped structure. Before the gas detection tube is used, the gas near the detection location is continuously absorbed by the gas clearing tube, which ensures that the gas absorbed by the gas detection tube at the detection location is the gas that is immediately leaking from the battery pack. The gas detection tube and the gas clearing tube work together to improve the measurement accuracy of the gas detection tube. Furthermore, by setting the suction port position at the lower end of the gas detection tube and the gas clearing tube to an arc-shaped structure, the detection location can be reached by only slightly tilting after being inserted, under the coordinated action of the motion component, even in narrow or offset detection locations, thus accommodating more detection locations.

[0009] Preferably, the gas detection tube includes a rigid tube section and a flexible tube section connected together. The rigid tube section is mounted on a second mounting plate, which has a mounting hole through which the rigid tube section connects. Alternatively, the flexible tube section is mounted on a first mounting plate, which has a through hole. A second support frame is mounted on the first mounting plate, connecting the flexible tube section. The through hole allows the flexible tube section to pass through and move. The rigid tube section is positioned and connected to the second mounting plate through the mounting hole, enabling it to transmit the impact force to the second mounting plate when subjected to an impact load. This drives the second mounting plate to move upward and compress a buffer spring for cushioning. Under the action of the second support frame, the flexible tube section is stably mounted on the first mounting plate and passes through the through hole to connect with the rigid tube section. Under the cushioning effect, the flexible tube section adapts and adjusts within the through hole.

[0010] The second aspect of this invention aims to solve the technical problem of low positioning accuracy in existing technologies. Furthermore, the mounting bracket is equipped with a positioning sensor for identifying the position of the gas detection tube, and an auxiliary calibration block is provided at the suction port of the gas detection tube. The positioning sensor can identify the relative gap between the suction port of the gas detection tube and the measurement position. Furthermore, the auxiliary calibration block at the suction port position, with its preset geometric features, enables the positioning sensor to quickly identify the suction port position of the gas detection tube, providing an absolute positioning reference for the tube and facilitating precise positioning of the suction gun at each measurement location.

[0011] The third aspect of this invention aims to solve the technical problem that some test locations are too limited, and the gas cleaning tube is prone to interference with the detection location. Further, the mounting frame includes a lifting module and a first support frame. The output end of the lifting module is connected to the first support frame, and the gas cleaning tube is mounted on the first support frame. The lifting module is used to adjust the height of the gas cleaning tube at the detection location; and / or, the second mounting plate has a through hole. In this solution, the relative height between the gas cleaning tube and the detection location is adjusted by the lifting module. If the detection location is too narrow, the gas cleaning tube is raised by the lifting module before it extends into the detection location, avoiding interference between the gas cleaning tube and the area around the detection location when the gas detection tube extends into the detection location, thus preventing interference with the insertion and detection of the gas detection tube.

[0012] A suction gun system includes a novel suction gun device and a detection component for detecting the gas absorbed by the gas detection tube.

[0013] The beneficial effect of this utility model is that when the air tube assembly collides with the object to be tested under the driving action of the motion component, the buffer component can buffer the impact load and avoid damage to the air tube assembly and suction gun device.

When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0018] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0019] Example 1

[0020] As attached Figure 1 To be continued Figure 2 As shown, this embodiment provides a novel suction gun device, including an air tube assembly 1, a mounting frame 2, and a motion assembly. The mounting frame 2 includes a first mounting plate 21, a second mounting plate 22, and a buffer assembly 3. The first mounting plate 21 is disposed opposite to the second mounting plate 22. The buffer assembly 3 is disposed between the first mounting plate 21 and the second mounting plate 22. The motion assembly is connected to the first mounting plate 21, and the air tube assembly 1 is mounted on the second mounting plate 22.

[0021] The position of the air tube assembly 1 relative to the test location is adjusted by the motion module, allowing the air tube assembly 1 to approach the test location for helium absorption and leakage detection. In dynamic testing, the motion module first moves the air tube assembly 1 to a position close to the test part, and then scans each test location sequentially along a predetermined route to check for leaks. When the air tube assembly 1 collides with the test object under the driving action of the motion module, the buffer component 3 can buffer the impact load to prevent damage to the air tube assembly 1 and the suction gun device.

[0022] The buffer assembly 3 includes multiple guide posts 31 and linear bearings 32. The multiple guide posts 31 are disposed at the edge positions of the first mounting plate 21 and the second mounting plate 22. The first mounting plate 21 has guide holes, and the linear bearings 32 are installed in the guide holes. The upper ends of the guide posts 31 are slidably connected to the linear bearings 32, and the bottom of the guide posts 31 is connected to the second mounting plate 22.

[0023] The linear bearing 32 slides with the guide post 31, which enables the second mounting plate 22 and its connected air pipe assembly 1 to move precisely and stably. When there is a collision, the second mounting plate 22 receives an upward impact load and moves along the axial direction of the guide post 31. This can prevent the second mounting plate 22 and its installed air pipe assembly 1 from being misaligned or stuck due to force offset, ensuring a smooth buffering process without generating additional lateral destructive force.

[0024] The buffer assembly 3 also includes an elastic element 33 sleeved on the outer wall of the guide post 31, with both ends of the elastic element 33 abutting against the opposing surfaces between the first mounting plate 21 and the second mounting plate 22, respectively. When the air tube assembly 1 collides, the spring is compressed or stretched, converting the instantaneous impact force into the elastic potential energy of the spring, significantly weakening the impact force and avoiding damage caused by hard contact. At the same time, after the collision, the spring can drive the detection head to reset, without affecting subsequent detection.

[0025] The guide post 31 cooperates with the linear bearing 32 to achieve smooth sliding of the first mounting plate and the second mounting plate. During the sliding process, the elastic element 33 is compressed and stretched, converting the impact force into elastic potential energy, thus achieving buffering. In this embodiment, the elastic element 33 can be a compression spring.

[0026] The tracheal assembly 1 includes a gas detection tube 11 and a gas clearing tube 12. The gas detection tube 11 is used to absorb the gas at the detection location for detection, and the gas clearing tube 12 is used to absorb excess gas before the gas detection tube 11 is used; and / or, the bottom of the gas detection tube 11 and the gas clearing tube 12 are arc-shaped structures.

[0027] Before the gas detection tube 11 is put into operation, the gas near the detection position is continuously absorbed by the gas clearing tube 12. This ensures that the gas absorbed by the gas detection tube 11 at the detection position is the gas that is leaking from the battery pack immediately. The gas detection tube 11 and the gas clearing tube 12 work together to improve the measurement accuracy of the gas detection tube 11. Furthermore, the suction port at the lower end of the gas detection tube 11 and the gas clearing tube 12 is set as an arc-shaped structure. When the detection position is narrow or offset to the side, it can reach the detection position by only slightly tilting after entering, under the coordinated action of the moving components, which can adapt to more detection positions.

[0028] The gas detection tube 11 includes a rigid tube section 111 and a flexible tube section 112 connected to each other. The rigid tube section 111 is mounted on a second mounting plate 22. The second mounting plate 22 has a mounting hole 23, and the rigid tube section 111 is connected to the mounting hole 23.

[0029] The flexible hose 112 is mounted on the first mounting plate 21. The first mounting plate 21 has a through hole 24. A second support frame 6 is mounted on the first mounting plate 21. The second support frame 6 is connected to the flexible hose 112. The through hole 24 is used for the flexible hose 112 to pass through and move.

[0030] The rigid tube 111 is positioned and connected to the second mounting plate 22 through the mounting hole 23, so that when the rigid tube 111 receives an impact load, it can transmit the impact force to the second mounting plate 22, drive the second mounting plate 22 to move upward and squeeze the buffer spring for buffering. The flexible tube 112 is stably installed on the first mounting plate 21 under the action of the second support frame 6, and passes through the through hole 24 to connect with the rigid tube 111. Under the buffering effect, the flexible tube 112 adapts and adjusts within the through hole 24.

[0031] Example 2

[0032] Based on Example 1, in order to ensure high accuracy in the arrival of the tracheal tube assembly 1 at the detection position, the mounting bracket 2 is equipped with a positioning sensor 7 for identifying the position of the tracheal tube 11, and an auxiliary calibration block 8 is provided at the suction port of the tracheal tube 11.

[0033] The positioning sensor 7 can identify the relative gap between the suction port of the gas detection tube 11 of the suction gun device and the measurement position. An auxiliary calibration block 8 is set at the suction port position of the gas detection tube 11. Through the preset geometric features of the auxiliary calibration block 8, the positioning sensor 7 can quickly identify the suction port position of the gas detection tube 11, providing an absolute positioning reference for the gas detection tube 11, which can facilitate the suction gun device to accurately position itself at each measurement position.

[0034] With the cooperation of positioning sensor 7 and auxiliary calibration block 8, the distance between gas detection tube 11 and detection position is controlled at 2~6mm.

[0035] To address the technical problem of interference between the air purification tube 12 and the detection position due to the limited testing location, the mounting frame 2 further includes a lifting module 4 and a first support frame 5. The output end of the lifting module 4 is connected to the first support frame 5, and the air purification tube 12 is mounted on the first support frame 5. The lifting module 4 is used to adjust the height of the air purification tube 12 at the detection position; and / or, the second mounting plate 22 has a through hole 24.

[0036] The relative height between the gas cleaning tube 12 and the detection position is adjusted by the lifting module 4. If the detection position is too narrow, the gas cleaning tube 12 is raised by the lifting module 4 before the gas detection tube 11 is inserted into the detection position. This avoids interference between the gas cleaning tube 12 and the detection position when the gas detection tube 11 is inserted into the detection position, which would affect the insertion and detection of the gas detection tube 11.
