[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] First embodiment
[0035] Please refer to Figure 1 , Figure 2 , Figure 3 , where Figure 1 is a schematic structural diagram of the first embodiment of a new energy battery housing airtightness and missing parts detector provided by the present invention; Figure 2 is Figure 1 the schematic structural diagram of the external three-dimensional shown; Figure 3 is Figure 1 the schematic structural diagram of the back of the overall structure shown. A new energy battery housing airtightness and missing parts detector includes: a fixing frame 1;
[0036] A workbench 2, the workbench 2 is fixedly installed on the top of the fixing frame 1;
[0037] A slide rail 3, the slide rail 3 is fixedly installed on the top of the outside of the fixing frame 1, the front and back sides of both sides of the slide rail 3 are slidably connected with slide seats 4, the top of the slide seat 4 is fixedly installed with a connecting column 5, the top of the connecting column 5 is fixedly installed with a fixing plate 6, and the top of the fixing plate 6 is fixedly installed with a cylinder 7;
[0038] A connecting frame 8, the connecting frame 8 is fixedly installed at the bottom of the output end of the cylinder 7, and the bottom of the connecting frame 8 is fixedly installed with a plurality of mounting seats 9, and the bottom of each of the plurality of mounting seats 9 is fixedly installed with a positioning structure and a missing parts detection mechanism 10.
[0039] A control chassis 11 is fixedly installed on the right side of the connecting column 5.
[0040] The control chassis 11 controls the work of all components and displays the working state.
[0041] The cylinder 7 cooperates with the connecting frame to press the housing, and then high-pressure steam and liquid are introduced for pressure holding test. If there is no pressure drop during the three-minute pressure holding, it is qualified.
[0042] Sensors are installed in the missing parts detection mechanism. If there are normal parts, they will be pushed against and there will be a normal display. If parts are missing, such as missing screws or welding, etc., an abnormality will be prompted.
[0043] The working principle of a new energy battery housing airtightness and missing parts detector provided by the present invention is as follows:
[0044] By placing its battery housing on the workbench 2, then starting the cylinder 7, due to the extending operation of the cylinder 7, it pushes the connecting frame 8 downward, and then due to the downward movement of the connecting frame 8, it drives the mounting seat 9, the missing part detection mechanism 10, and the positioning structure to move downward. When the bottom of the connecting frame 8 contacts the top of the housing and exerts a certain degree of extrusion on it, it is sufficient. When the housing has poor airtightness, it will deform when being extruded, while when its sealing is good, it will not deform.
[0045] During the airtightness detection, the positioning structure positions the housing, and at the same time, the sensor in the missing part detection mechanism 10 conducts the missing part detection and induction work.
[0046] After one detection work is completed, by pushing the connecting column 5, due to the force movement of the connecting column 5, it drives the sliding seat 4 to move on the surface of its slide rail 3. At the same time, the connecting frame 8, the cylinder 7, the mounting seat 9, the missing part detection mechanism 10, and the control chassis 11 move synchronously to other positions of the housing and then conduct the detection work at other positions.
[0047] Compared with the related technology, a new energy battery housing airtightness and missing part detection machine provided by the present invention has the following beneficial effects:
[0048] Through the mutual cooperation among structures such as the fixing frame 1, the workbench 2, the slide rail 3, the sliding seat 4, the connecting column 5, the fixing plate 6, the cylinder 7, the connecting frame 8, the mounting seat 9, and the missing part detection mechanism 10, the cylinder 7 can push the connecting frame 8, the mounting seat 9, the missing part detection mechanism 10, and the positioning structure downward until the bottom of the connecting frame 8 contacts the top of the battery housing and exerts extrusion on it, thus conducting the airtightness detection work, and the missing part detection work is carried out by the missing part detection mechanism 10. The two work synchronously, so time can be saved and work efficiency can be improved.
[0049] Second Embodiment
[0050] Please refer to Figure 4 、 Figure 5 and Figure 6 Based on a new energy battery housing airtightness and missing part detection machine provided in the first embodiment of the present application, the second embodiment of the present application proposes another new energy battery housing airtightness and missing part detection machine. The second embodiment is only a preferred way of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0051] Specifically, the difference of a new energy battery housing airtightness and missing parts detector provided by the second embodiment of the present application lies in that for a new energy battery housing airtightness and missing parts detector, first sliding grooves 12 are provided on both the front and back of the bottom of the fixing frame 1, and first sliders 13 are slidably connected inside the first sliding grooves 12.
[0052] Through the mutual cooperation among the first sliding grooves 12, the first sliders 13 and the fixing columns 14, it is possible to store the moving base 15 and the backing plate 21 inside the fixing frame 1 when not in use, thereby saving the usage space.
[0053] A fixing column 14 is fixedly installed inside the first slider 13, and a moving base 15 is fixedly installed on the left side of the fixing column 14.
[0054] Rollers are fixedly installed on both the front and back of the left side of the bottom of the moving base 15, and the moving base 15 is supported by the contact between the rollers and the ground, avoiding the instability of the left side part being suspended.
[0055] Second sliding grooves 16 are provided on the periphery of the front of the moving base 15, second sliders 17 are slidably connected inside the second sliding grooves 16, and a linkage column 18 is fixedly installed inside the second slider 17.
[0056] A double-axis telescopic rod 19 is fixedly installed inside the linkage column 18, and the fixed end of the double-axis telescopic rod 19 is fixedly installed on the front of the moving base 15 through a connecting block.
[0057] Through the mutual cooperation between the second sliding grooves 16 and the second sliders 17, it is possible to improve the stability of the movement of the linkage column 18 and at the same time improve the force distribution of the linkage column 18, avoiding the situation that the force acts completely on the linkage column 18 and causing it to fail completely.
[0058] Connecting rods 20 are rotatably connected to both the front and back of the top of the linkage column 18, and a backing plate 21 is rotatably connected to the top of the connecting rods 20.
[0059] Third sliding grooves 22 are provided on both sides of the front of the backing plate 21, third sliders 23 are slidably connected inside the third sliding grooves 22, and a push column 24 is fixedly installed on the front of the third slider 23.
[0060] A communication groove 25 is provided on the front of the backing plate 21 and inside the third sliding groove 22, a threaded rod 26 is arranged inside the communication groove 25, and a threaded block 27 is sleeved on the surface of the threaded rod 26.
[0061] Both sides of the threaded block 27 are fixedly installed on the inner side of the third slider 23 through mounting posts, and a motor 28 is fixedly installed at the bottom of the threaded rod 26 and at the bottom of the backing plate 21.
[0062] The working principle of a new energy battery case airtightness and missing part detector provided by the present invention is as follows:
[0063] Just place its case on the backing plate 21 and on the right side of the push post 24. Subsequently, start the double-shaft telescopic rod 19. Through the retraction of the double-shaft telescopic rod 19, the linkage column 18 is driven to move from the outside to the inside. Then, through the movement of the linkage column 18, the second slider 17 is driven, causing the second slider 17 to move from the outside to the inside in the second chute 16. Then, through the movement of the linkage column 18, the connecting rod 20 is driven to move. Subsequently, due to the angular change generated by the movement of the connecting rod 20, the backing plate 21 and the case are pushed upward until they move upward to a suitable position.
[0064] Subsequently, the motor 28 can be started. Through the rotation of the motor 28, the threaded rod 26 is driven to rotate. Then, due to the rotation of the threaded rod 26, the threaded block 27 sleeved on its surface is driven to move, and the threaded block 27 moves inside its communication groove 25. Subsequently, due to the movement of the threaded block 27, the third slider 23 is driven, causing the third slider 23 to move from the left to the right inside its third chute 22. Through the movement of the third slider 23, the push post 24 is driven to move from the left to the right. Then, due to the movement of the push post 24, the case is pushed, causing the case to move to the right on the top of the backing plate 21. Thus, the case is pushed from the backing plate 21 onto the detection platform on the fixed frame 1.
[0065] When not in use, the moving base 15 can be pushed to the right, causing the moving base 15 to move to the right under force and drive the fixed column 14 to move. Then, through the movement of the fixed column 14, the first slider 13 is driven, causing the first slider 13 to move from the left to the right in the first chute 12, so that structures such as the moving base 15 and the backing plate 21 are retracted inside the fixed frame 1 for storage.
[0066] Compared with the related technology, a new energy battery case airtightness and missing part detector provided by the present invention has the following beneficial effects:
[0067] Through the mutual cooperation among structures such as the first sliding groove 12, the first sliding block 13, the fixed column 14, the moving base 15, the second sliding groove 16, the second sliding block 17, the linkage column 18, the double-axis telescopic rod 19, the connecting rod 20, the backing plate 21, the third sliding groove 22, the third sliding block 23, the pushing column 24, the communication groove 25, the threaded rod 26, the threaded block 27, the motor 28, etc., the battery housing can be transported onto the backing plate 21 and then pushed onto the workbench 2 for inspection before the inspection of the battery housing, without the need for workers to lift it to an appropriate height and then place it on the workbench 2. Therefore, the labor intensity of workers can be reduced, and the situation of lumbar muscle strain caused by long-term labor during lifting can be avoided.
[0068] Third Embodiment
[0069] Please refer to Figure 7 and Figure 8 Based on a new energy battery housing airtightness and missing parts detector provided in the first embodiment of the present application, another new energy battery housing airtightness and missing parts detector is proposed in the third embodiment of the present application. The third embodiment is only a preferred manner of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.
[0070] Specifically, the difference of a new energy battery housing airtightness and missing parts detector provided in the third embodiment of the present application is that, for a new energy battery housing airtightness and missing parts detector, fourth sliding grooves 29 are opened at the four peripheries of the top of the workbench 2, fourth sliding blocks 30 are slidably connected inside the fourth sliding grooves 29, nuts 31 are fixedly installed on the outer sides of the fourth sliding blocks 30, and locking bolts 32 are arranged inside the nuts 31.
[0071] Through the mutual cooperation between the fourth sliding groove 29 and the fourth sliding block 30, the position of pressing the housing can be changed according to the actual situation, thus improving the adaptability of the overall structure in use.
[0072] A square hollow column 33 is rotatably connected inside the locking bolt 32, and an extension column 34 is arranged inside the square hollow column 33.
[0073] The extension column 34 can be drawn out from the square hollow column 33, so the use length of the square hollow column 33 is changed, and thus the pressing work can be carried out on housings of different widths.
[0074] The working principle of a new energy battery housing airtightness and missing parts detector provided by the present invention is as follows:
[0075] By placing its housing on the workbench 2 and then inserting the housing through the gap between the top of the workbench 2, the extension column 34 and the square hollow column 33, the square hollow columns 33 and the extension column 34 at four different positions are located at the top of the housing while the housing is at the top of the workbench 2. Then, by pulling the extension column 34 inward, the extension column 34 is forced to extend outward from the inside of its square hollow column 33 to extend the service length of the square hollow column 33.
[0076] Subsequently, manually rotate the locking bolt 32 and control the square hollow column 33 so that the locking bolt 32 does not drive the square hollow column 33 to rotate when it rotates. Subsequently, due to the rotation of the locking bolt 32 and the fact that the nut 31 is in a stationary state, the locking bolt 32 moves downward inside the nut 31 as it rotates. Then, the downward movement of the locking bolt 32 drives the square hollow column 33 and the extension column 34 to move downward until the housing is pressed against the workbench 2 by the square hollow column 33 and the extension column 34.
[0077] When using the square hollow column 33 and the extension column 34, the fourth slider 30 can be pushed to cause the fourth slider 30 to move in the fourth chute 29, thereby driving the service positions of the square hollow column 33 and the extension column 34 until they are adjusted to appropriate positions.
[0078] Compared with the related art, a new energy battery housing airtightness and missing parts detector provided by the present invention has the following beneficial effects:
[0079] Through the mutual cooperation among structures such as the fourth chute 29, the fourth slider 30, the nut 31, the locking bolt 32, the square hollow column 33, and the extension column 34, the housing can be fixed on the workbench 2 during the detection work, avoiding the situation of position deviation during the detection work or before waiting for detection. Therefore, the stability of the housing detection work can be improved.
[0080] The above are only embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
