Description

Technical Field

[0001] This invention relates to the field of compressive strength testing technology, specifically to a compressive strength testing device for the production of battery covers made of fiber materials. Background Technology

[0002] With the advancement of technology and the enhancement of environmental awareness, fiber materials have been increasingly widely used in the production of battery covers due to their advantages such as being lightweight, high-strength, environmentally friendly, and recyclable. However, fiber material battery covers need to meet strict standards in terms of compressive strength to ensure their safety and reliability during use. Therefore, it is particularly important to test the compressive strength of fiber material battery covers. Currently, there are some devices on the market for testing the compressive strength of battery covers made of fiber materials. These devices usually use traditional testing methods, such as pressing a heavy object directly onto the battery cover and evaluating its compressive strength by observing the degree of deformation or cracking of the battery cover. In addition, some advanced devices have introduced sensors and data processing systems, which can more accurately measure the deformation and stress distribution of the battery cover during the compression process. Although existing technologies have made some progress in testing the compressive strength of fiber material battery covers, some significant shortcomings still exist: Insufficient test accuracy: Traditional heavy object testing methods often cannot accurately control the impact force and impact time, resulting in large errors in the test results. At the same time, since the heavy object may rebound during the fall, it will cause a secondary impact on the battery cover, further affecting the accuracy of the test. Complex operation and low efficiency: Although some existing advanced devices can improve the accuracy of testing, the operation process is relatively complex and requires professional personnel to operate and maintain them. This not only increases production costs but also reduces testing efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a compressive strength testing device for the production of battery covers made of fiber materials, thus solving the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a compressive strength testing device for producing battery covers of fiber materials, comprising a base, a fixed frame fixedly connected to the top of the base, guide rods fixedly connected to both sides of the base, an impact component that moves downward to impact the battery cover on the guide rods, a control component that locks the impact component on the fixed frame, and anti-rebound components that prevent the impact component from rebounding downward on both sides of the base. The anti-rebound assembly includes mounting blocks fixedly installed on both sides of the bottom of the base, a fixing plate between the two mounting blocks, a second vertical rod fixedly connected to one side of the top of the fixing plate, a horizontal bar fixedly connected to the side of the second vertical rod near the impact assembly, and a stop block for preventing the counterweight plate from rebounding slidably connected to the horizontal bar.

[0005] As a further preferred embodiment of this technical solution, a second damping spring sleeved on the crossbar is provided between the stop block and the second vertical rod, and a sleeve block is fixedly connected to the outer wall of the stop block.

[0006] As a further preferred embodiment of this technical solution, a first vertical rod is fixedly connected to one side of the top of the fixed plate.

The second mounting bracket is located above the mounting bracket. A lever plate is rotatably connected to the mounting bracket. Protruding rods are fixedly connected to both sides of the lever plate and at the lower position. A pressure rod is rotatably connected to the second mounting bracket. The top of the pressure rod is in contact with the bottom side wall of the sleeve block, and the bottom side wall of the pressure rod is in contact with the upper side wall of the lever plate.

[0007] As a further preferred embodiment of this technical solution, the bottom of the sleeve block near the pressure rod is provided with a first rounded corner, the pressure rod near the top of the first vertical rod is provided with a second rounded corner, and a third damping spring is provided between the second vertical rod and the first vertical rod, with the third damping spring located above the second mounting bracket.

[0008] As a further preferred embodiment of this technical solution, a rotating shaft is rotatably connected to the mounting block, a first bevel gear is fixedly connected to the outer end of the rotating shaft, a disc is rotatably connected to both ends of the fixing plate, a second bevel gear that meshes with the first bevel gear is fixedly connected to the center of the disc shaft, and a toggle rod is provided on the side wall of the disc, and the positions of the toggle rod and the protruding rod correspond to each other.

[0009] As a further preferred embodiment of this technical solution, synchronous pulleys are provided on the rotating shaft and the fixed frame, and the two synchronous pulleys are driven by a synchronous belt.

[0010] As a further preferred embodiment of this technical solution, the rear end of the base is provided with sliding grooves on both sides. A first rectangular groove and a second rectangular groove are provided from top to bottom at the sliding groove. The second rectangular groove is connected to the first rectangular groove and the sliding groove. A positioning rod is fixedly connected to the inner wall of the first rectangular groove. A sleeve rod is slidably connected to the positioning rod. A first damping spring is sleeved on the outer wall of the positioning rod. A right-angle block and a rectangular block are fixedly connected to the outer walls of both ends of the sleeve rod, respectively. A collar is sleeved on the outer wall of the sleeve rod, and multiple collars are fixedly connected by a connecting rod. A first cylinder is fixedly installed on the base at the upper and lower ends of the connecting rod.

[0011] As a further preferred embodiment of this technical solution, the impact assembly includes a counterweight plate slidably mounted on a guide rod. Connecting plates are fixedly connected to both sides of the rear end of the counterweight plate, and the positions of the connecting plates and the right-angle blocks correspond to each other. Horizontal plates are fixedly connected to the left and right ends of the counterweight plate, and the positions of the horizontal plates and the stop blocks correspond to each other. Extension blocks are fixedly mounted on the counterweight plate on both sides of the horizontal plates, and the extension blocks are fixedly connected to the timing belt. A T-shaped block is connected to the top of the counterweight plate through a second cylinder. A striking block is fixedly connected to the bottom of the counterweight plate. The striking block is used to perform impact testing on the battery cover.

[0012] As a further preferred embodiment of this technical solution, the control component includes a second cylinder fixedly installed on the top of the fixed frame, a rack fixedly connected to the output end of the second cylinder, gears installed at the bottom of the fixed frame meshing on both sides of the rack, and a locking rod that is compatible with the T-block fixedly connected to the outer wall of the gear.

[0013] Compared with existing technologies, it has the following advantages: Through a carefully designed anti-rebound component, the anti-rebound action is automatically triggered after the impact component impacts the battery cover. This mechanism effectively prevents the impact component from rebounding and causing a secondary impact on the battery cover, thus ensuring the independence and accuracy of each impact test. Due to the precise design and automated operation of the anti-rebound component, it can quickly and effectively prevent the impact component from rebounding after impact, avoiding test errors caused by secondary impacts. This greatly improves the accuracy and reliability of the test, making the test results more accurate and credible.

[0014] The entire testing device has a compact structure and the components work together closely and efficiently. For example, the transmission of the synchronous belt and synchronous pulley, as well as the meshing of the bevel gears, achieves precise synchronization of the impact action and the anti-rebound action. This design not only improves the working efficiency of the device but also reduces the failure rate. Furthermore, since the testing device can automatically complete the impact test and the anti-rebound action, it greatly saves the time of manual operation. This not only improves production efficiency but also reduces the test error caused by human error.

[0015] By moving the connecting plates on both sides of the counterweight plate to the top of the right-angle block, the initial positions of the counterweight plate and the striking block can be easily adjusted. This adjustment mechanism allows testers to precisely set the impact force of the striking block on the battery cover when it falls, according to different test requirements. This flexibility ensures that the test can cover a wider range of impact conditions, improving the comprehensiveness and accuracy of the test. When an impact test is required, activating the first cylinder can automatically move the connecting rod, collar, rectangular block, sleeve rod, and right-angle block. The result of this series of actions is that the right-angle block fully enters the second rectangular slot, thereby releasing the counterweight plate and causing it to move the striking block downwards under the action of gravity, applying an impact to the battery cover. This automated testing process not only improves testing efficiency but also reduces errors caused by human operation. The introduction of the first damping spring provides stable resistance to the movement of the sleeve rod, which helps to maintain the stability of the system when adjusting the position of the counterweight plate. At the same time, when the right-angle block is fully entered into the second rectangular slot, the compression state of the first damping spring also ensures that the counterweight plate can fall smoothly when released, avoiding impact fluctuations caused by sudden release, thereby improving the accuracy of the test.

[0016] By controlling the limit of the T-block by the control component, the timing of when the counterweight plate and the striking block at its bottom begin to fall for impact testing can be precisely controlled. This precise control ensures that the impact force and timing of the striking block on the battery cover are consistent in each test, thereby improving the accuracy and repeatability of the test.

[0019] The technical solutions in the embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Combining Figures 1-8 As shown, the present invention provides a technical solution: a compressive strength testing device for the production of battery covers made of fiber materials, including a base 1, a battery cover to be tested placed on the base 1, a fixed frame 2 fixedly connected to the top of the base 1, guide rods 3 fixedly connected to both sides of the base 1, an impact component 4 for impacting the battery cover by moving downward on the guide rods 3, a control component 5 for locking the impact component 4 on the fixed frame 2, and anti-rebound components 6 for preventing the impact component 4 from rebounding downward on both sides of the base 1; The anti-rebound assembly 6 includes mounting blocks 61 fixedly installed on both sides of the bottom end of the base 1. A fixing plate 66 is provided between the two mounting blocks 61. A second vertical rod 68 is fixedly connected to one side of the top of the fixing plate 66. A horizontal rod 69 is fixedly connected to the side of the second vertical rod 68 near the impact assembly 4. A stop block 610 for preventing the counterweight plate 41 from rebounding is slidably connected to the horizontal rod 69. A second damping spring 612 is provided between the stop block 610 and the second vertical rod 68 and sleeved on the horizontal rod 69. A sleeve block 611 is fixedly connected to the outer wall of the stop block 610, and a first rounded corner 613 is provided at the bottom of the sleeve block 611 near the pressure rod 618. A first vertical rod 67 is fixedly connected to one side of the top of the fixing plate 66. A mounting bracket 614 and a second mounting bracket 615 are fixedly connected to the side of the first vertical rod 67 near the second vertical rod 68. The second mounting bracket 615 is located above the mounting bracket 614. A lever 616 is rotatably connected to the mounting bracket 614. A protruding rod 617 is fixedly connected to the side and below. A pressure rod 618 is rotatably connected to the second mounting bracket 615. The top of the pressure rod 618 is in contact with the bottom side wall of the sleeve block 611, and the bottom side wall of the pressure rod 618 is in contact with the upper side wall of the lever plate 616. A second rounded corner 620 is provided on the side of the pressure rod 618 near the top of the first vertical rod 67. The second rounded corner 620 and the first rounded corner 613 facilitate the movement and reset of the stop block 610 and the sleeve block 611 after the test. A third damping spring 619 is provided between the second vertical rod 68 and the first vertical rod 67. The third damping spring 619 is located above the second mounting bracket 615. The elastic force of the third damping spring 619 pushes the pressure rod 618 to rotate, so that the top of the pressure rod 618 contacts the bottom outer wall of the sleeve block 611, so that the pressure rod 618 blocks the sleeve block 611, thereby ensuring that the battery cover can effectively prevent its rebound after being impacted, and ensuring the accuracy of the test. A rotating shaft 62 is rotatably connected to the mounting block 61. A first bevel gear 65 is fixedly connected to the outer end of the rotating shaft 62. A disc 621 is rotatably connected to both ends of the fixing plate 66. A second bevel gear 622 that meshes with the first bevel gear 65 is fixedly connected to the center of the disc 621. A toggle lever 623 is provided on the side wall of the disc 621, and the positions of the toggle lever 623 and the protrusion 617 correspond to each other. The rotating shaft 62 and the fixed frame 2 are provided with synchronous pulleys 63, and the two synchronous pulleys 63 are driven by the synchronous belt 64.

[0021] In an embodiment of the present invention, when the counterweight plate 41 moves downward in the mechanical device and drives the extension block 44, the extension block 44 moves downward accordingly, thereby effectively driving the synchronous belt 64 to rotate. The rotation of the synchronous belt 64 is transmitted to the synchronous pulley 63, causing the rotating shaft 62 and the first bevel gear 65 to rotate accordingly. The first bevel gear 65 meshes with the second bevel gear 622. Therefore, when the first bevel gear 65 rotates, the second bevel gear 622, as well as the disk 621 and the actuating rod 623 connected to it, will also rotate accordingly. At this time, the rotation of the actuating rod 623 will actuate the cam 617, thereby driving the actuating plate 616 to rotate counterclockwise. Figure 8 As shown, the counterclockwise rotation of the lever 616 will push the pressure rod 618 to rotate clockwise under the elastic force of the third damping spring 619, ensuring that the pressure rod 618 always maintains its blocking effect on the sleeve block 611. As the counterweight plate 41 moves downward and impacts the battery cover, it rebounds upward due to the impact force. This rebound, via the extension block 44, causes the synchronous belt 64 to rotate in the opposite direction. The reverse rotation of the synchronous belt 64 then causes the synchronous pulley 63, the rotating shaft 62, and the first bevel gear 65 to rotate in the opposite direction. The reverse rotation of the first bevel gear 65 causes the second bevel gear 622, the disc 621, and the actuating lever 623 to also rotate in the opposite direction. The reverse rotation of the actuating lever 623 actuates the cam 617, thereby causing the dial plate 616 to rotate clockwise. Figure 8 As shown, the clockwise rotation of the lever 616 will push the pressure rod 618 to rotate counterclockwise and compress the third damping spring 619. At this time, the pressure rod 618 no longer blocks the sleeve block 611, causing the stop block 610 to move inward under the elastic force of the second damping spring 612. The inward movement of the stop block 610 will block the horizontal plate 43 after it moves upward, thereby preventing the counterweight plate 41 from falling back under the action of gravity and causing a secondary impact on the battery cover. In this way, after the impact component 4 impacts the battery cover, it will automatically trigger the anti-rebound component 6, causing the stop block 610 to move inward and prevent the impact component 4 from impacting the battery cover a second time. This series of actions ensures that the test results of each impact test are more accurate and improves the accuracy and reliability of the test.

[0022] Example 2: Combination Figure 3As shown, based on Embodiment 1, the base 1 has sliding grooves 11 on both sides of the rear end. A row of first rectangular grooves 12 and second rectangular grooves 13 are opened from top to bottom at the sliding grooves 11. The second rectangular grooves 13 are connected to the first rectangular grooves 12 and sliding grooves 11. A positioning rod 14 is fixedly connected to the inner wall of the first rectangular groove 12. A sleeve rod 15 is slidably connected to the positioning rod 14. A first damping spring 17 is sleeved on the outer wall of the positioning rod 14. A right-angle block 16 and a rectangular block 18 are fixedly connected to the outer walls of both ends of the sleeve rod 15, respectively. A collar 19 is sleeved on the outer wall of the sleeve rod 15. Multiple collars 19 are fixedly connected by a connecting rod 110. A first cylinder 111 is fixedly installed on the base 1 at the upper and lower ends of the connecting rod 110.

[0023] In an embodiment of the present invention, if it is necessary to adjust the initial position of the counterweight plate 41 and the striking block 46 during the battery cover impact test, it can be achieved by simply moving the connecting plates 42 on both sides of the counterweight plate 41 to the top of the right-angle block 16. This adjustment allows us to change the impact force of the striking block 46 on the battery cover when it falls, so that different impact forces can be applied to the battery cover for accurate impact testing according to different test requirements. When the counterweight plate 41 and the striking block 46 need to be moved downwards for impact testing, the operator can activate the first cylinder 111. This action will cause the connecting rod 110 and the collar 19 to move to one side of the positioning rod 14. As the collar 19 moves, the rectangular block 18, the sleeve 15, and the right-angle block 16 will also move towards the positioning rod 14, and will compress the first damping spring 17. As a result of this series of actions, the right-angle block 16 is completely inserted into the second rectangular groove 13, ensuring that the right-angle block 16 is no longer located at the bottom of the counterweight plate 41. At this time, the counterweight plate 41 will drive the striking block 46 to move downwards under the action of gravity, and apply an impact to the battery cover to complete the impact test.

[0024] Example 3: Combination Figure 2 As shown, based on Embodiment 2, the impact assembly 4 includes a counterweight plate 41 slidably mounted on the guide rod 3. Connecting plates 42 are fixedly connected to both sides of the rear end of the counterweight plate 41, and the positions of the connecting plates 42 and the right-angle block 16 correspond to each other. Horizontal plates 43 are fixedly connected to the left and right ends of the counterweight plate 41, and the positions of the horizontal plates 43 and the stop block 610 correspond to each other. Extension blocks 44 are fixedly mounted on the counterweight plate 41 on both sides of the horizontal plates 43, and the extension blocks 44 are fixedly connected to the synchronous belt 64. A T-shaped block 45 is connected to the top of the counterweight plate 41 through a second cylinder 51. By opening the second cylinder 51, the T-shaped block 45 can be driven to move up and down at the top of the counterweight plate 41. A striking block 46 is fixedly connected to the bottom of the counterweight plate 41. The striking block 46 is used to perform impact testing on the battery cover.

[0025] In an embodiment of the present invention, after the control component 5 stops performing limit control on the T-block 45, the right-angle block 16 is controlled to start moving into the interior of the base 1. This action causes the right-angle block 16 to no longer obstruct the counterweight plate 41 and releases the restriction on the counterweight plate 41. Therefore, the counterweight plate 41 begins to move downward under the influence of its own weight, thereby enabling the striking block 46 to perform an impact test on the battery cover located on the base 1. As the counterweight plate 41 moves downward, it can also drive the horizontal plate 43 and the extension block 44 to move downward together. As the extension block 44 moves downward, it will further cause the timing belt 64 to rotate on the timing pulley 63.

[0026] Example 4: Combination Figure 2 As shown, based on Embodiment 1, the control component 5 includes a second cylinder 51 fixedly installed on the top of the fixed frame 2. A rack 52 is fixedly connected to the output end of the second cylinder 51. Gears 53 installed at the bottom of the fixed frame 2 are meshed on both sides of the rack 52. A locking rod 54 that is compatible with the T-block 45 is fixedly connected to the outer wall of the gear 53.

[0027] In an embodiment of the present invention, when it is necessary to release the counterweight plate 41, the second cylinder 51 is activated to drive the rack 52 downward. The rack 52 drives the meshing gears 53 on both sides to rotate, which in turn causes the gears 53 to drive the locking rod 54 to rotate outward, so that the locking rod 54 no longer acts as a locking mechanism. Under its own weight, the counterweight plate 41 drives the striking block 46 to move downward and impact the battery cover.
