Description

Technical Field

[0001] The present invention specifically relates to a compressive strength detection device for battery housing production. Background Art

[0002] With the wide application of lithium-ion batteries in fields such as electric vehicles and energy storage systems, the safety issues of batteries have become increasingly prominent. As a key component for protecting the internal structure of the battery, the compressive strength of the battery housing is directly related to the overall safety and reliability of the battery. Therefore, strict compressive strength detection of the battery housing has become an important means to ensure battery safety.

[0003] For example, the publication number is CN117347152A. This invention discloses a compressive strength detection device for battery housing in new energy vehicle production, including a base, a workbench, and a mounting frame. A moving seat is fixedly installed inside the mounting frame. By setting a cylinder, a pressing plate, and a detection rod, the hydraulic cylinder pushes the pressing plate to squeeze the battery. When the second screw rotates, the second moving block drives the detection seat to move, and the detection rod detects the battery. The detection rod transmits the signal to the corresponding cylinder position, and the cylinder ejects the corresponding battery, and the detection is fast and simple.

[0004] In the above-mentioned prior art, the staff places the battery housing in the placement groove, squeezes the battery through the hydraulic cylinder pushing the pressing plate, and then detects it through the detection rod. If the detected housing is unqualified, the battery housing is ejected by the cylinder. However, in the daily use of the battery, impacts may also occur from the side, and the above-mentioned and traditional detection methods are all for front compressive strength detection. Therefore, there will be deviations in the compressive strength data. For this reason, we propose a compressive strength detection device for battery housing production. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, the staff inserts the battery housings into both sides of the first placement box. The conveying of the chain can drive the movement of the first placement box. The first placement box moves into the interior of the detection cover, and the movement of the first placement box can drive the movement of the support movable head. The support movable head drives the guide slider to move through the guide support rod. The guide slider slides along the track of the guide groove. Since two high and low points are arranged in the middle of the guide groove, the first placement box is in an inclined state after moving to this position, and the two high and low points are opposite, so the inclined states of the first placement box are opposite. When reaching the high and low points, the movement stops. Through the compressive detection of the detection rod and the detection head, the side detection of the housing is realized, improving the accuracy of the detection data. When the housing is detected, the backing plate and the fixed support rod can support the first placement box, avoiding the instability of the housing during the compressive detection and the damage of the first placement box.

[0024] 2. In the present invention, by setting the second collection box, when unqualified housings appear during the compressive detection of the housing, some housings will have fragments flying off, and the second collection box can collect the flying fragments, thus avoiding the fragments flying around. When detecting for a long time and a certain amount of fragments are collected inside the second collection box, the screw rod can be rotated. The screw rod drives the pushing plate to push the fragments inside the second collection box, so that the fragments fall into the collection box through the second discharge port for collection.

[0025] 3. In the present invention, the chain drives the first placement box to move, so as to transport the outer shell. When it is transported to the mounting rack, the flatness detector detects the compression surface of the outer shell. If the compression surface is intact, the second cylinder on the right is started. The second cylinder drives the second synchronization plate to rise, and the second synchronization plate drives the unloading block to rise. Moreover, the unloading block passes through the area where the outer shells on both sides of the first placement box are located, so as to squeeze the outer shell into the collection groove on the right for collection. If the detected outer shell is damaged, the second cylinder on the left is started, so that the damaged outer shell falls into the collection groove on the left for collection. And when the first placement box carrying the damage moves gradually downward, the debris carried on the surface slides into the first collection box for collection, avoiding such debris falling to other places and making it difficult to collect.

Detailed implementation manners

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-9 , the present invention provides a technical solution: a battery housing production compressive testing device, including:

[0038] A workbench 1, on which a detection component for pressing the battery is provided;

[0039] A driving component, arranged in the middle of the inner side of the workbench 1, and a chain 34 for conveying the battery is installed on the driving component;

[0040] A placement component, arranged on the chain 34 for placing the battery;

[0041] A collection component, arranged on the inner side of the workbench 1 and corresponding to the lower part of the detection component, for collecting the damaged battery housing during detection;

[0042] A collection groove 14, arranged at the bottom end of the inner side of the workbench 1, and a discharge component for pushing the battery out of the placement component is provided on one side of the inner side of the workbench 1 corresponding to the collection groove 14;

[0043] Wherein, a guide groove 13 for tilting the placement component is opened on the inner wall of the workbench 1.

[0044] Preferably, the placing component includes a first placing box 41. At both ends of the first placing box 41 close to one side of the chain 34, slide rails 46 are fixedly connected. A support movable head 47 is slidably connected to the middle of the slide rails 46. A guiding support rod 48 is rotatably connected to the middle of the support movable head 47. One end of the guiding support rod 48 away from the first placing box 41 is rotatably connected to a guiding slider 49, and the guiding slider 49 is slidably connected to the guiding groove 13. At the bottom end of the first placing box 41, a backing plate 410 is slidably connected to the ends of the slide rails 46 close to each other. A fixed support rod 411 is fixedly connected to the bottom end of the backing plate 410, and the fixed support rod 411 is fixedly connected to the workbench 1. At the middle of the first placing box 41 close to one side of the chain 34, a connecting shaft 43 is fixedly connected. A support shaft 44 is rotatably connected to the middle of the connecting shaft 43. A fixed seat 45 is fixedly connected to the side of the support shaft 44 close to the chain 34. The fixed seats 45 are arranged in an annular array at equal intervals and fixed on the outer side of the chain 34. Discharge slots 42 are formed at both ends of the first placing box 41 away from the chain 34. The driving component includes a motor 31, a rotating shaft 32 and a gear 33. The motor 31 is arranged at the end of the inner side of the workbench 1, and one end of the motor 31 is connected to the rotating shaft 32. A gear 33 matching with the chain 34 is installed on the rotating shaft 32. The detecting component includes a detecting cover 21. The detecting cover 21 is fixed on the top of the workbench 1. First cylinders 22 are fixedly connected to the middle of the detecting cover 21 at equal intervals. The bottom ends of the first cylinders 22 penetrate through the detecting cover 21 and are aligned with the second collecting box 51. A first synchronizing plate 23 is fixedly connected to the bottom ends of the first cylinders 22. Detecting rods 24 are fixedly connected to both sides of the bottom end of the first synchronizing plate 23. A detecting head 25 is fixedly connected to the bottom end of the detecting rod 24.

[0045] In this embodiment, the staff inserts the battery housing into both sides of the first placement box 41, starts the motor 31. When the motor 31 starts, it drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the gear 33 to rotate, the gear 33 drives the chain 34 to rotate, and the chain 34 drives the first placement box 41 to be transported. The first placement box 41 moves into the interior of the detection cover 21, and the movement of the first placement box 41 can drive the support moving head 47 to move. The support moving head 47 drives the guide slider 49 to move through the guide support rod 48. The guide slider 49 slides along the track of the guide groove 13. Since two sets of high and low points are arranged in the middle of the guide groove 13, the first placement box 41 is in an inclined state after moving here, and the support moving head 47 will slide along the track of the slide rail 46, so that the first placement box 41 can be tilted smoothly. And the two sets of high and low points are opposite, so the inclined states of the first placement box 41 are opposite. When reaching the high and low points, the movement stops. Start the first cylinder 22, and the first cylinder 22 pushes the first synchronous plate 23 to move downward. The first synchronous plate 23 pushes the detection rod 24 and the detection head 25 to move. Through the compressive detection of the detection rod 24 and the detection head 25, the side detection of the housing is realized, improving the accuracy of the detection data. When the housing is detected, the backing plate 410 and the fixed support rod 411 can support the first placement box 41 to prevent the housing from being unstable during the compressive detection and the first placement box 41 from being damaged. When the detection from the high and low points is completed, it is conveyed to the bottom end of the leftmost first synchronous plate 23, and the leftmost detection rod 24 and detection head 25 perform a front detection on the housing.

[0046] As Figure 1 - Figure 9 As shown, the collection assembly includes a second collection box 51. The second collection boxes 51 are arranged at equal intervals and fixed in the middle of the workbench 1 where the chain 34 is located, and are located at the bottom end of the fixed support rod 411 and are fixedly connected to the fixed support rod 411. A second discharge port 53 is opened on one side of each second collection box 51; A lead screw 52 is rotatably connected to the middle of the second collection box 51. One end of the lead screw 52 passes through the second discharge port 53. A push plate 54 is threadedly connected to the end of the lead screw 52 located inside the second collection box 51. The push plate 54 is slidably connected to the second collection box 51 and the fixed support rod 411.

[0047] In this embodiment, when unqualified housings appear during the compressive detection of the housing, some housings will have fragments flying off, and the second collection box 51 can collect the flying fragments, thus preventing the fragments from scattering everywhere. When detecting for a long time and a certain amount of fragments are collected inside the second collection box 51, the lead screw 52 can be rotated. The lead screw 52 drives the push plate 54 to push the fragments inside the second collection box 51, so that the fragments fall into the collection box 12 through the second discharge port 53 for collection.

[0048] As Figure 1 - Figure 9As shown in the figure, the unloading assembly includes a second cylinder 61. The second cylinder 61 is fixed to one side of the collection tank 14. The top end of the second cylinder 61 is fixedly connected to a second synchronization plate 62. Both sides of the top end of the second synchronization plate 62 are fixedly connected to unloading blocks 63. A first discharge port 11 is arranged at equal intervals on one side of the workbench 1. The first discharge port 11 communicates with the second discharge port 53. A collection box 12 is fixedly connected to the bottom end of the workbench 1 where the first discharge port 11 is located. An installation frame 15 is fixedly connected to one side of the workbench 1 close to the collection tank 14. A flatness detector 16 is fixedly connected to the middle of the side of the installation frame 15 close to the workbench 1. A first collection box 17 is fixedly connected to the bottom end of the workbench 1 where the installation frame 15 is located, and the first collection box 17 is located at the top end of the left collection tank 14.

[0049] In this embodiment, the model of the flatness detector 16 is ZLDS202. The chain 34 continues to drive the first placement box 41 to move for transporting the outer shell. When it is transported to the installation frame 15, the flatness detector 16 detects the compression surface of the outer shell. If the compression surface is intact, the right second cylinder 61 is started. The second cylinder 61 drives the second synchronization plate 62 to rise. The second synchronization plate 62 drives the unloading blocks 63 to rise, and the unloading blocks 63 pass through the area where the outer shells on both sides of the first placement box 41 are located, so as to squeeze the outer shell into the right collection tank 14 for collection. If the detected outer shell is damaged, the left second cylinder 61 is started, so that the damaged outer shell falls into the left collection tank 14 for collection. And when the first placement box 41 carrying the damage moves gradually downward, the debris carried on the surface slides into the first collection box 17 for collection, avoiding the difficulty of collecting such debris falling to other places. Therefore, continuous detection is realized.

[0050] Working principle and usage process of the present invention: First, the staff inserts the battery housing into both sides of the first placement box 41, starts the motor 31. The start of the motor 31 drives the rotation of the rotating shaft 32, the rotating shaft 32 drives the rotation of the gear 33, the gear 33 drives the rotation of the chain 34, and the chain 34 drives the transportation of the first placement box 41. The first placement box 41 moves into the interior of the detection cover 21, and the movement of the first placement box 41 can drive the movement of the support movable head 47. The support movable head 47 drives the guide slider 49 to move through the guide support rod 48. The guide slider 49 slides along the track of the guide groove 13. Since two high and low points are provided in the middle of the guide groove 13, the first placement box 41 is in an inclined state after moving to this position, and the support movable head 47 will slide along the track of the slide rail 46, so that the first placement box 41 can be smoothly inclined. And the two high and low points are opposite, so the inclined states of the first placement box 41 are opposite. When reaching the high and low points, the movement stops. Start the first cylinder 22, the first cylinder 22 pushes the first synchronous plate 23 to move downward, the first synchronous plate 23 pushes the detection rod 24 and the detection head 25 to move, and through the compressive detection of the detection rod 24 and the detection head 25, the side detection of the housing is realized, improving the accuracy of the detection data. When the housing is detected, the backing plate 410 and the fixed support rod 411 can support the first placement box 41 to prevent the housing from being unstable during the compressive detection and the first placement box 41 from being damaged. When the detection from the high and low points is completed, it is conveyed to the bottom of the first synchronous plate 23 on the leftmost side, and the leftmost detection rod 24 and the detection head 25 perform a front detection on the housing. And when there are unqualified housings during the compressive detection of the housing, some housings will have fragments flying off, and the second collection box 51 can collect the flying fragments, thus preventing the fragments from flying around. When detecting for a long time and a certain amount of fragments are collected inside the second collection box 51, the lead screw 52 can be rotated. The lead screw 52 drives the push plate 54 to push the fragments inside the second collection box 51, so that the fragments fall into the collection box 12 through the second discharge port 53 for collection. Then the chain 34 continues to drive the first placement box 41 to move and transport the housing. When it is transported to the mounting frame 15, the flatness detector 16 detects the compressive surface of the housing. If the compressive surface is intact, start the second cylinder 61 on the right side. The second cylinder 61 drives the second synchronous plate 62 to rise, the second synchronous plate 62 drives the unloading block 63 to rise, and the unloading block 63 passes through the area where the housings are located on both sides of the first placement box 41, so as to squeeze the housing into the right collection groove 14 for collection. If the detected housing is damaged, start the second cylinder 61 on the left side, so that the damaged housing falls into the left collection groove 14 for collection. And when the damaged first placement box 41 moves gradually downward while carrying the fragments on its surface, the fragments slide into the first collection box 17 for collection, preventing such fragments from falling to other places and being difficult to collect. Therefore, continuous detection is achieved.
