Description

Technical Field

[0001] The present invention relates to the technical field of battery protective shells, and in particular to a lightweight, impact-resistant battery protective shell quality detection device. Background Art

[0002] A battery protective casing is an outer shell used to protect batteries from external physical damage, chemical corrosion, or accidental short circuits. This type of casing can be applied to a variety of battery types, including but not limited to mobile phone batteries, laptop batteries, electric vehicle batteries, and battery packs in energy storage systems. Battery protective casings are an essential component for ensuring safe battery operation, and it is crucial to select the appropriate material and design based on the needs of different application scenarios.

[0003] Existing battery protective casing quality inspection devices typically use tests such as extrusion, mechanical impact, and simulated collision to complete the quality inspection of the battery protective casing. Since existing battery protective casing quality inspection devices mostly perform segmented inspections, they cannot simultaneously detect the extrusion and mechanical impact of the battery protective casing. This causes an offset during the quality inspection of the battery protective casing, resulting in deviations in the quality inspection data and reducing the accuracy of the inspection device for the battery protective casing quality inspection.

[0004] At the same time, the battery protective shell quality inspection device lacks the classification and processing of qualified products and defective products, which requires staff to manually screen the battery protective shells, causing defective products to flow into the market, thereby reducing the efficiency of the overall device in inspecting the quality of the battery protective shells and affecting the quality of the subsequent use of the battery protective shells. Therefore, the existing battery protective shell quality inspection device needs to be improved to a certain extent. Summary of the Invention

[0016] Preferably, the outer wall of the fixing frame is slidably connected to a push ring, and the outer wall of the push ring is fixedly connected to a cylinder, one end of the cylinder is fixedly connected to a No. 2 bearing ring, and the inner wall of the No. 2 bearing ring is slidably connected to a No. 3 fixing rod.

[0017] Preferably, the cylinder forms a rotating structure through the No. 2 bearing ring and the No. 3 fixed rod, and the push ring forms a telescopic structure through the cylinder, the baffle forms a pushing structure through the fixed frame and the push ring, and the baffle forms an angle adjustment structure through the No. 2 adjustment ring and the adjustment frame.

[0018] In order to solve the above technical problems, the present invention also proposes a lightweight impact-resistant battery protective shell quality detection device and a method for using the lightweight impact-resistant battery protective shell quality detection device, which includes the following steps:

[0019] Step 1: First, place the battery protective shell body to be inspected above the conveying device, and then start the No. 1 motor set on the outside of the frame. At this time, the No. 1 motor drives the conveying device to work, so that the conveying device drives the battery protective shell body to convey. When one end of the battery protective shell body contacts the baffle, the No. 2 motor is started. At this time, the No. 2 motor drives the No. 1 transmission rod to rotate, so that the No. 1 bevel gear fixed on the outer wall of the No. 1 transmission rod rotates synchronously, thereby driving the meshing No. 2 bevel gear to rotate through the No. 1 bevel gear, and then driving the No. 2 bevel gear fixed at the other end to rotate synchronously through the connecting rod, so that the No. 2 bevel gear drives the No. 1 transmission rod to rotate through the second No. 1 bevel gear;

[0020] Since the inner wall of the bevel gear set is fixedly connected to the No. 1 transmission rod and the No. 1 threaded rod, the No. 1 threaded rod rotates synchronously with the No. 1 transmission rod through the bevel gear set, so that the No. 1 threaded rod drives the threaded sleeve connected to the outer wall to be telescopically adjusted along the positioning frame, thereby driving the two extrusion plates to move toward the center through the two threaded sleeves, and then the extrusion plates drive the sliding rod to slide and adjust along the positioning frame, so that the two extrusion plates perform an extrusion test on the battery protective shell body, and at the same time complete the position limiting of the battery protective shell body;

[0021] Step 2: When the No. 1 transmission rod drives the No. 1 bevel gear to rotate through the No. 2 motor, the No. 1 bevel gear drives the meshing No. 3 bevel gear to rotate, so that the No. 3 bevel gear drives the No. 2 transmission rod to rotate. Since the No. 1 fixed rod and the No. 2 transmission rod are provided on the inner wall of the transmission, the No. 1 fixed rod is driven by the transmission to adjust synchronously, and then the No. 1 fixed rod drives the fixed ring to rotate. At this time, the fixed ring drives the adjusting roller to perform circular motion through the connecting rod, so that the adjusting roller contacts the protrusion during the movement.

[0022] The adjusting roller drives the protrusion and the adjusting rod to push, and then the adjusting rod drives the punching hammer to adjust the angle along the positioning frame. Since the pressure adjustment mechanism assembly is arranged between the adjusting rod and the protective shell, the protective shell compresses and adjusts the pressure adjustment mechanism assembly when the adjusting rod adjusts the angle. When the adjusting roller is disengaged from the protrusion, the adjusting rod is reset through the pressure adjustment mechanism assembly, so that the adjusting rod drives the punching hammer to punch the battery protective shell body, completing the extrusion test of the battery protective shell body and the punching test at the same time.

[0023] Step 3: When the staff needs to adjust the force of the punching test of the punching hammer, the No. 1 adjusting ring is rotated to drive the threaded ring to rotate along the adjusting sleeve. Since the inner wall of the threaded ring is threadedly connected to the No. 2 threaded rod, the length of the No. 2 threaded rod is adjusted by the threaded ring, and then the No. 2 threaded rod drives the connecting frame to be adjusted synchronously. Since the outer walls of the connecting frame and the No. 1 mounting frame are both engaged and connected with hooks, the connecting frame and the No. 1 mounting frame adjust the stretching length of the reset spring through the hook, so that the subsequent adjusting rod changes the strength of the return force of the reset spring, thereby completing the adjustment of the impact force of the battery protective shell body;

[0024] Step 4: When the inspector needs to classify the battery protective shell body, the cylinder is activated to drive the push ring to adjust the extension and contraction. Since the outer wall bearing of the push ring is connected to the fixed frame, the fixed frame pushes the baffle through the push ring, and then the baffle is adjusted along the adjustment frame through the No. 2 adjustment ring. At the same time, the cylinder rotates along the No. 3 fixed rod through the No. 2 bearing ring, ensuring the stability of the baffle angle adjustment;

[0025] When the battery protective shell body is detected to be qualified, the baffle drives the second adjustment ring to rotate 90 degrees along the adjustment frame through the tension of the cylinder, so that the qualified battery protective shell body is conveyed along the conveying device. When the battery protective shell body is detected to be unqualified, the baffle rotates 45 degrees so that the battery protective shell body is conveyed to the top of the conveying frame through the baffle. At this time, the conveying roller rotates through the positioning rod so that the battery protective shell body slides along the conveying roller, completing the processing of the unqualified battery protective shell body.

[0026] Compared with the prior art, the beneficial effects of the present invention are: the quality detection device for a lightweight and impact-resistant battery protective shell;

[0027] 1. Through the No. 1 bevel gear, threaded sleeve, driver and protective shell, gear transmission is combined with thread telescopic adjustment to complete the extrusion of both sides of the battery protective shell body. At the same time, a belt is used for synchronous transmission and reset adjustment to complete the stamping of the battery protective shell body. This solves the problem that the existing lightweight and impact-resistant battery protective shell quality inspection device cannot synchronously detect the extrusion and mechanical impact of the battery protective shell, thereby facilitating the staff to synchronously detect the extrusion and mechanical impact of the battery protective shell, improving the staff's efficiency in inspecting the quality of the battery protective shell, and preventing the battery protective shell from offsetting during quality inspection, resulting in deviation in quality inspection data, thereby ensuring the accuracy of the inspection device for the quality of the battery protective shell;

[0028] 2. The pressure adjustment mechanism component is provided, and the thread adjustment is used to drive the stretching length adjustment to complete the adjustment of the spring rebound force strength. This solves the problem that the existing lightweight impact-resistant battery protective shell quality inspection device cannot adjust the punching strength of the battery protective shell body. This facilitates the staff to adjust the punching strength of the battery protective shell, ensures the stability of the punching strength of the battery protective shell by the staff, and saves the time of the inspection personnel in adjusting the punching strength. It improves the efficiency of the lightweight impact-resistant battery protective shell quality inspection device for battery protective shell quality inspection and increases the practicality of the overall device.

[0029] 3. Through the classification and conveying mechanism components and conveying racks, the cylinder is used to drive the push ring for telescopic adjustment. At this time, the push ring pushes the baffle through the fixed frame, so that the baffle can be adjusted along the adjustment frame through the No. 2 adjustment ring for angle adjustment, thereby completing the subsequent classification and conveying of the battery protective shell body after inspection, solving the problem that the existing battery protective shell quality inspection device cannot classify qualified products and defective products, thereby facilitating the staff to quickly screen the battery protective shells, improving the efficiency of subsequent staff in classifying the battery protective shells, and preventing manual screening errors by inspection personnel, resulting in defective products flowing into the market, thereby ensuring the quality of the battery protective shells used in the subsequent market.

The inner wall of the conveying rack 32 is fixedly connected with a positioning rod 33, and the outer wall bearing of the positioning rod 33 is connected to the conveying roller 34.

[0045] The specific implementation method is as follows: through the classification and conveying mechanism assembly 31 and the conveying frame 32, the cylinder 3106 is used to drive the push ring 3105 to perform telescopic adjustment. At this time, the push ring 3105 pushes the baffle 3103 through the fixed frame 3104, so that the baffle 3103 is adjusted along the adjustment frame 3101 through the No. 2 adjustment ring 3102 to complete the subsequent classification and conveying of the battery protective shell body 4 after inspection, solving the problem that the existing battery protective shell quality inspection device cannot classify and process qualified products and defective products, thereby facilitating the staff to quickly screen the battery protective shell, improving the efficiency of subsequent staff in classifying and processing the battery protective shell, and preventing the inspection personnel from making mistakes in manual screening, resulting in defective products flowing into the market, thereby ensuring the quality of the battery protective shell used in the subsequent market.

[0046] Working principle: When using the device for detecting the quality of lightweight and impact-resistant battery protective shells, first place the battery protective shell body 4 to be detected above the conveying device 3, and then start the No. 1 motor 2 arranged on the outside of the frame 1. At this time, the No. 1 motor 2 drives the conveying device 3 to work, so that the conveying device 3 drives the battery protective shell body 4 to be conveyed. When one end of the battery protective shell body 4 contacts the baffle 3103, start the No. 2 motor 5. At this time, the No. 2 motor 5 drives the No. 1 transmission rod 6 to rotate, so that the No. 1 bevel gear 7 fixed on the outer wall of the No. 1 transmission rod 6 rotates synchronously, thereby driving the meshing No. 2 bevel gear 8 to rotate through the No. 1 bevel gear 7, and then driving the No. 2 bevel gear 8 fixed at the other end to rotate synchronously through the connecting rod 9, so that the No. 2 bevel gear 8 drives the No. 1 transmission rod 6 to rotate through the second No. 1 bevel gear 7;

[0047] Since the inner wall of the bevel gear set 11 is fixedly connected to the No. 1 transmission rod 6 and the No. 1 threaded rod 12, the No. 1 threaded rod 12 rotates synchronously with the No. 1 transmission rod 6 through the bevel gear set 11, so that the No. 1 threaded rod 12 drives the threaded sleeve 13 threadedly connected to the outer wall to perform telescopic adjustment along the positioning frame 16, thereby driving the two extrusion plates 14 to move toward the center through the two threaded sleeves 13, and then the extrusion plates 14 drive the sliding rod 15 to slide and adjust along the positioning frame 16, so that the two extrusion plates 14 perform an extrusion test on the battery protective shell body 4, and at the same time complete the limitation of the battery protective shell body 4;

[0048] When the No. 1 transmission rod 6 drives the No. 1 bevel gear 7 to rotate through the No. 2 motor 5, the No. 1 bevel gear 7 drives the meshing No. 3 bevel gear 17 to rotate, so that the No. 3 bevel gear 17 drives the No. 2 transmission rod 18 to rotate. Since the No. 1 fixed rod 20 and the No. 2 transmission rod 18 are provided on the inner wall of the transmission 19, the No. 1 fixed rod 20 is driven by the transmission 19 to adjust synchronously, and then the No. 1 fixed rod 20 drives the fixing ring 23 to rotate. At this time, the fixing ring 23 drives the adjusting roller 25 to perform a circular motion through the connecting rod 24, so that the adjusting roller 25 contacts the protrusion 29 during the movement.

[0049] Thus, the adjusting roller 25 drives the protrusion 29 and the adjusting rod 27 to push, and then the adjusting rod 27 drives the punching hammer 28 to adjust the angle along the positioning frame 16. Since the pressure adjustment mechanism assembly 30 is arranged between the adjusting rod 27 and the protective shell 21, the protective shell 21 cooperates with the pressure adjustment mechanism assembly 30 to compress and adjust the pressure adjustment mechanism assembly 30 when the adjusting rod 27 adjusts the angle. When the adjusting roller 25 is disengaged from the protrusion 29, the adjusting rod 27 is reset by the pressure adjustment mechanism assembly 30, so that the adjusting rod 27 drives the punching hammer 28 to punch the battery protective shell body 4, completing the extrusion test of the battery protective shell body 4 and the punching test at the same time.

[0050] When the staff needs to adjust the force of the punching test of the punching hammer 28, the No. 1 adjusting ring 3007 is rotated at this time, so that the No. 1 adjusting ring 3007 drives the threaded ring 3006 to rotate along the adjusting sleeve 3008. Since the inner wall of the threaded ring 3006 is threadedly connected to the No. 2 threaded rod 3005, the length of the No. 2 threaded rod 3005 is adjusted by the threaded ring 3006, and then the No. 2 threaded rod 3005 drives the connecting frame 3004 to be synchronously adjusted. Since the outer walls of the connecting frame 3004 and the No. 1 mounting frame 3001 are both engaged and connected with the hook 3002, the connecting frame 3004 and the No. 1 mounting frame 3001 adjust the stretching length of the return spring 3003 through the hook 3002, so that the subsequent adjusting rod 27 changes the strength of the rebound force of the return spring 3003, thereby completing the adjustment of the impact force of the battery protective shell body 4;

[0051] When the inspector needs to classify the battery protective shell body 4, the cylinder 3106 is activated to drive the push ring 3105 to perform telescopic adjustment. Since the outer wall bearing of the push ring 3105 is connected to the fixing frame 3104, the fixing frame 3104 pushes the baffle 3103 through the push ring 3105, and then the baffle 3103 is adjusted along the adjustment frame 3101 through the second adjustment ring 3102. At the same time, the cylinder 3106 rotates along the third fixing rod 3108 through the second bearing ring 3107, thereby ensuring the stability of the angle adjustment of the baffle 3103.

[0052] When the battery protective shell body 4 is detected to be qualified, the baffle 3103 drives the second adjusting ring 3102 to rotate 90° along the adjusting frame 3101 through the pulling force of the cylinder 3106, so that the qualified battery protective shell body 4 is conveyed along the conveying device 3. When the battery protective shell body 4 is detected to be unqualified, the baffle 3103 is rotated 45°, so that the battery protective shell body 4 is conveyed to the top of the conveying frame 32 through the baffle 3103. At this time, the conveying roller 34 is rotated by the positioning rod 33, so that the battery protective shell body 4 slides along the conveying roller 34, completing the processing of the unqualified battery protective shell body 4.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

At this time, the No. 1 motor (2) drives the conveying device (3) to work, so that the conveying device (3) drives the battery protective shell body (4) to convey. When one end of the battery protective shell body (4) contacts the baffle (3103), start the No. 2 motor (5). At this time, the No. 2 motor (5) drives the No. 1 transmission rod (6) to rotate, so that the No. 1 bevel gear (7) fixed on the outer wall of the No. 1 transmission rod (6) rotates synchronously, thereby driving the meshing No. 2 bevel gear (8) to rotate through the No. 1 bevel gear (7), and then driving the No. 2 bevel gear (8) fixed at the other end to rotate synchronously through the connecting rod (9), so that the No. 2 bevel gear (8) drives the No. 1 transmission rod (6) to rotate through the second No. 1 bevel gear (7); Since the inner wall of the bevel gear set (11) is respectively fixedly connected with the No. 1 transmission rod (6) and the No. 1 threaded rod (12), the No. 1 threaded rod (12) rotates synchronously with the No. 1 transmission rod (6) through the bevel gear set (11), so that the No. 1 threaded rod (12) drives the threaded sleeve (13) threadedly connected to the outer wall to perform telescopic adjustment along the positioning frame (16), thereby driving the two extrusion plates (14) to move toward the center through the two threaded sleeves (13), and then the extrusion plates (14) drive the sliding rod (15) to slide and adjust along the positioning frame (16), so that the two extrusion plates (14) perform an extrusion test on the battery protective shell body (4), and at the same time complete the limit of the battery protective shell body (4); Step 2: When the No. 1 transmission rod (6) drives the No. 1 bevel gear (7) to rotate through the No. 2 motor (5), the No. 1 bevel gear (7) drives the meshing No. 3 bevel gear (17) to rotate, so that the No. 3 bevel gear (17) drives the No. 2 transmission rod (18) to rotate. Since the inner wall of the transmission device (19) is provided with the No. 1 fixed rod (20) and the No. 2 transmission rod (18), the No. 1 fixed rod (20) is driven by the transmission device (19) to perform synchronous adjustment, and then the No. 1 fixed rod (20) drives the fixed ring (23) to rotate. At this time, the fixed ring (23) drives the adjusting roller (25) to perform circular motion through the connecting rod (24), so that the adjusting roller (25) contacts the protrusion (29) during the movement; Thus, the adjusting roller (25) drives the protrusion (29) and the adjusting rod (27) to push, and then the adjusting rod (27) drives the punching hammer (28) to adjust the angle along the positioning frame (16). Since the pressure adjustment mechanism assembly (30) is arranged between the adjusting rod (27) and the protective shell (21), when the adjusting rod (27) adjusts the angle, the protective shell (21) cooperates with the pressure adjustment mechanism assembly (30) to perform compression adjustment on the pressure adjustment mechanism assembly (30). When the adjusting roller (25) is separated from the protrusion (29), the adjusting rod (27) is reset through the pressure adjustment mechanism assembly (30), so that the adjusting rod (27) drives the punching hammer (28) to punch the battery protective shell body (4), and completes the extrusion test of the battery protective shell body (4) and the punching test at the same time; Step 3: When the staff needs to adjust the force of the punching test of the punching hammer (28), the first adjusting ring (3007) is rotated so that the first adjusting ring (3007) drives the threaded ring (3006) to rotate along the adjusting sleeve (3008). Since the inner wall of the threaded ring (3006) is threadedly connected with the second threaded rod (3005), the length of the second threaded rod (3005) is adjusted by the threaded ring (3006), and the second threaded rod (3005) drives the second threaded rod (3005) to rotate. The movable connecting frame (3004) is adjusted synchronously. Since the outer walls of the connecting frame (3004) and the first mounting frame (3001) are both engaged and connected with the hook (3002), the connecting frame (3004) and the first mounting frame (3001) adjust the stretching length of the return spring (3003) through the hook (3002), so that the subsequent adjustment rod (27) changes the strength of the resilience of the return spring (3003), thereby completing the adjustment of the impact force of the battery protective shell body (4); Step 4: When the inspector needs to classify the battery protective shell body (4), the cylinder (3106) is started to drive the push ring (3105) to perform telescopic adjustment. Since the outer wall bearing of the push ring (3105) is connected to the fixed frame (3104), the fixed frame (3104) pushes the baffle (3103) through the push ring (3105), and then the baffle (3103) is adjusted along the adjustment frame (3101) through the second adjustment ring (3102). At the same time, the cylinder (3106) is rotated along the third fixed rod (3108) through the second bearing ring (3107), thereby ensuring the stability of the angle adjustment of the baffle (3103); When the battery protective shell body (4) is found to be qualified, the baffle (3103) drives the second adjustment ring (3102) to rotate 90° along the adjustment frame (3101) through the pulling force of the cylinder (3106), so that the qualified battery protective shell body (4) is transported along the conveying device (3); when the battery protective shell body (4) is found to be unqualified, the baffle (3103) rotates 45°, so that the battery protective shell body (4) is transported to the top of the conveying frame (32) through the baffle (3103), and the conveying roller (34) rotates through the positioning rod (33), so that the battery protective shell body (4) slides along the conveying roller (34), and the unqualified battery protective shell body (4) is processed.
