[0002] In the inspection of car lights, the quality of the headlight cover directly affects the lighting effect and service life of the car lights. After the injection molding of the headlight cover and headlight shell and other injection molded parts are completed, the headlight cover needs to be inspected to ensure the effect after being put into use.

[0003] A strength testing device for the production of new energy vehicle headlight covers, with publication number CN221405197U, has the following problem raised in its background technology: during the testing process, the strength performance of the same impact object when hitting the same position of the headlight cover with different forces is also very different. However, the device is not able to implement relevant tests for this situation.

[0004] Based on the existing technology, there are the following problems: The existing vehicle lamp cover strength detection device usually adopts the traditional multi-point clamping method to fix the vehicle lamp cover, which results in that the position where the multi-point clamping mechanism contacts the vehicle lamp cover and the position where the multi-point clamping mechanism does not contact the vehicle lamp cover have different support strengths after collision or extrusion, thereby reducing the detection accuracy and not being suitable for the actual use of the vehicle lamp cover. The vehicle lamp cover is broken during the detection process. The existing vehicle lamp cover strength detection device is not convenient for collecting and cleaning the generated fragments, and is not convenient for long-term detection and use. Referring to the above application documents, although it is convenient to perform strength detection on the vehicle lamp cover from different angles, when the vehicle lamp cover is subjected to strength detection, the support strengths of the clamped part and the non-clamped part are different, which affects the accuracy of the strength detection and is not convenient for collecting and cleaning the fragments generated during the detection process, and is not convenient for long-term use. There are certain deficiencies. In order to solve the above problems, an intelligent strength detection device and method based on vehicle lamp injection molding mold processing are proposed.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 , an intelligent strength detection device based on the processing of the injection molding mold of the lamp, comprising a body 1, a fixing mechanism 2 arranged on the inner side of the body 1 for fixing the lamp cover, a collecting mechanism 3 arranged at the bottom of the fixing mechanism 2 for cleaning the debris in the detection process, and a detection mechanism 4 arranged on the inner side of the body 1 for detecting the strength of the lamp cover; See also Figure 6 , Figure 7 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.16 and Fig.17 , the fixing mechanism 2 comprises: The turntable 21 is rotatably disposed on the inner side of the body 1. The side wall of the turntable 21 is provided with a shielding component 24 for shielding debris. The side of the turntable 21 away from the detection mechanism 4 is provided with a limiting component 23 arranged in a ring array. The limiting component 23 includes; A fixed seat 231 is fixedly arranged on a side of the turntable 21 away from the detection mechanism 4. A movable plate 233 arranged symmetrically with respect to the center point of the fixed seat 231 is movably arranged on the side of the fixed seat 231 away from the turntable 21. A limiting groove 2391 is provided on the side of the movable plate 233 close to the fixed seat 231. A limiting hole 2392 is provided on the inner wall of the limiting groove 2391. A limiting sleeve 239 is sleeved on the inner wall of the limiting sleeve 239. A screw 26 is sleeved on the inner wall of the limiting sleeve 239. The first limiting slot 235 is formed on a side of the fixing seat 231 close to the rotating disk 21 , so that the screw rod 26 extends along the first limiting slot 235 to a side of the fixing seat 231 close to the rotating disk 21 .

[0024] The outer surface and inner surface of the longitudinal section of the limiting sleeve 239 are respectively designed in a regular hexagon and a circular shape, and the inner wall of the limiting groove 2391 is designed in a regular hexagon and is adapted to the outer wall of the limiting sleeve 239; The inner diameter of the limiting groove 2391 is larger than the inner wall diameter of the limiting hole 2392, so as to limit the limiting sleeve 239 embedded in the limiting groove 2391, and after the limiting sleeve 239 is embedded in the limiting groove 2391, the side of the limiting sleeve 239 close to the rotating disk 21 is in contact with the side of the fixing seat 231 away from the rotating disk 21, and the fixing mechanism 2 also includes; The second limiting grooves 25 are opened in a circular array on the side wall of the turntable 21 and are arranged corresponding to the positions of the first limiting grooves 235 so that the screw rod 26 extends along the first limiting grooves 235 and the second limiting grooves 25 to the side of the turntable 21 away from the fixing seat 231.

[0025] The limiting component 23 also includes: The fixed plate 232 is fixedly arranged on the side of the fixed seat 231 away from the rotating disk 21, and is symmetrically arranged with respect to the center point of the fixed seat 231. The first slide groove 234 is provided on the side of the fixed plates 232 close to each other, and the inner walls on both sides of the first slide groove 234 extend to the outside of the fixed plate 232. The first slide grooves 234 are provided with first sliders symmetrically arranged with respect to the center point of the first slide groove 234. The first sliders are provided with disassembly and assembly components 238 on the side of the first sliders close to each other, and the first sliders are connected to the movable plate 233 through the disassembly and assembly components 238. The screw rod 236 is rotatably arranged on the side wall of the fixed plate 232 and extends into the first slide groove 234. The screw rod 236 is designed as a bidirectional screw rod 236. The side wall of one end of the screw rod 236 located in the first slide groove 234 is threadedly connected to the first slider to make the movable plates 233 approach or move away from each other. The side wall of one end of the screw rod 236 located outside the fixed plate 232 is fixedly sleeved with a first gear. A rotating rod is rotatably arranged on one side of the turntable 21 close to the fixed seat 231. The two ends of the side wall of the rotating rod are respectively fixedly sleeved with a second gear and a bevel gear 237. The two sides of the second gear are respectively meshed with the two first gears.

[0026] In the specific implementation, the screw 26 for fixing the lamp housing is extended along the limiting hole 2392, the inner wall of the limiting sleeve 239, the first limiting slot 235 and the second limiting slot 25 to the side of the turntable 21 close to the detection mechanism 4, and then the screw 26 is rotated, and the screw hole installation part of the lamp housing is connected with the side wall of the end of the screw 26 located on the turntable 21 close to the detection mechanism 4, so as to fix the lamp housing, and since the lamp cover and the lamp housing are usually connected by means of buckles and glue, the connection between the lamp cover and the lamp housing is a prior art and is not described here, so as to connect the lamp cover with the lamp housing, so as to fix the lamp cover, and after the lamp cover and the lamp housing are connected, the strength of the lamp cover is tested, so as to facilitate the subsequent detection mechanism 4 to perform strength testing on the lamp cover, and during the strength testing, it is convenient to grasp the strength of the connection between the lamp cover and the lamp housing, so as to facilitate grasping the stability of the lamp cover connected to the lamp housing after impact or pressure; When performing strength testing on lamp covers of different sizes, the corresponding lamp shells need to be installed first. To this end, by rotating the screw rod 236, the screw rod 236 drives the first slider to move closer to or away from each other along the first slide groove 234 during the rotation process, thereby adjusting the position of the movable plate 233 to be suitable for lamp shells of different sizes, thereby facilitating the fixing of lamp covers of different sizes. Different lamp shells use different screw rods 26. To this end, the movable plate 233 is separated from the first slider by the disassembly assembly 238. The movable plate 233 is separated from the side of the fixed plate 232 where they are close to each other, so that the limiting sleeve 239 is taken out from the limiting groove 2391, so as to replace the limiting sleeve 239 corresponding to the lamp housing, so as to limit the screw rod 26, and avoid the situation that the screw rod 26 is loosened due to the gap between them after passing through the limiting sleeve 239, or the situation that the screw rod 26 cannot pass through the inner wall of the limiting sleeve 239, so as to adapt to lamp housings of different sizes, and thus fix lamp covers of different sizes; By making the limiting sleeve 239 embedded in the movable plate 233 along the limiting groove 2391, and by making the inner wall diameter of the limiting hole 2392 smaller than the inner diameter of the limiting groove 2391, when the limiting sleeve 239 is embedded in the limiting groove 2391, the side wall of the movable plate 233 located outside the limiting hole 2392 limits the limiting sleeve 239, and when the movable plate 233 is connected to the first slider through the disassembly assembly 238, the limiting sleeve 239 is fitted with the side of the fixing seat 231 away from the rotating disk 21, so that the two ends of the limiting sleeve 239 are limited, so that the limiting sleeve 239 can be replaced easily while ensuring its stability; By making the inner wall of the limiting sleeve 239 circular, when the screw 26 passes through the limiting hole 2392 and the inner wall of the limiting sleeve 239, the rotation of the screw 26 is not affected, which is convenient for fixing the lamp housing, thereby facilitating the actual fixing of the lamp cover. The outer wall of the limiting sleeve 239 fits the inner wall of the limiting groove 2391 and both are designed in a regular hexagonal shape, thereby limiting the limiting sleeve 239 to prevent it from rotating and improving stability. The headlight cover is fixed by the headlight shell. Since the bending part of the side wall of the headlight cover is in full contact with the headlight shell, after the headlight cover is compressed or impacted, the supporting effect of the headlight cover is in line with reality, so it is convenient to carry out strength testing in line with reality. Compared with the traditional method of fixing the headlight cover by multi-point clamping for strength testing, the headlight cover can be fixed by the headlight shell. The different supporting effects of the positions where the traditional multi-point clamping mechanism contacts and does not contact the headlight cover after being compressed or impacted during the testing process can be reduced, thereby reducing the different crushing degrees at the clamping position and the non-clamping position, which affects the accuracy of the strength testing. Moreover, by making the headlight shell fully contact with the edge of the headlight cover, i.e. the bending position, it is convenient to grasp the strength at the edge of the headlight cover during the strength testing process, so as to carry out intelligent strength testing on the headlight cover. By rotating the turntable 21, it is convenient to make the headlight cover fixed by the limit assembly 23 correspond to the position of the detection mechanism 4, so that the detection mechanism 4 can perform strength detection on the headlight cover in the horizontal position, and it is convenient to install multiple headlight covers to improve the efficiency of strength detection. The rotation of the turntable 21 makes it convenient for fragments to fall downward during the detection process, thereby facilitating the collection of the shielding assembly 24.

[0027] The fixing mechanism 2 also includes: The first servo motor 22 is fixedly arranged on the inner side of the machine body 1. The output shaft of the first servo motor 22 is fixedly provided with a first rotating shaft through a coupling. The side wall of one end of the first rotating shaft away from the first servo motor 22 is fixedly connected to the rotating disk 21, so that the first servo motor 22 drives the rotating disk 21 to rotate. The bevel gear plate 27 is rotatably arranged at the center of one side of the turntable 21 close to the fixed seat 231, and the bevel gear plate 27 is meshed with the bevel gear 237. The inner wall of the bevel gear plate 27 is fixedly sleeved with a sleeve rod 29, and the sleeve rod 29 is hollow in design. The inner wall of the sleeve rod 29 is rotatably connected to the side wall of the first rotating shaft. A second servo motor 28 is fixedly arranged on the inner side of the body 1, and the output shaft of the second servo motor 28 is fixedly arranged with a second rotating shaft through a coupling. The side wall of the second rotating shaft and the outer wall of the sleeve rod 29 are fixedly provided with mutually meshing transmission gears, so that the second servo motor 28 drives the bevel gear plate 27 to rotate.

[0028] In a specific implementation, the first servo motor 22 is started, and the output shaft of the first servo motor 22 drives the first rotating shaft to rotate through the coupling, and the first rotating shaft drives the turntable 21 to rotate. When the first servo motor 22 drives the turntable 21 to rotate, the bevel gear 237 is meshed and driven along the bevel gear plate 27, and the second servo motor 28 can be rotated at this time to avoid movement obstacles between the first servo motor 22 and the second servo motor 28, so as to facilitate the adjustment of the position of the movable plate 233; The second servo motor 28 is started, and the second servo motor 28 drives the second rotating shaft to rotate through the coupling, and the second rotating shaft drives the sleeve rod 29 to rotate through the transmission gear, and the sleeve rod 29 drives the bevel gear plate 27 to rotate, thereby driving the bevel gear 237, the rotating rod and the second gear to rotate, so as to drive the first gear and the screw rod 236 to rotate, so as to facilitate the synchronous adjustment of the positions of the multiple moving plates 233, and facilitate the actual adjustment and use. The meshing direction of the bevel gear 237 and the bevel gear plate 27 and the threaded connection direction of the screw rod 236 and the first slider are matched, so as to facilitate the moving plates 233 to move closer to or farther away from each other, so as to facilitate the actual operation; A mounting plate is fixedly provided on the inner side of the machine body 1, and the top of the mounting plate is fixedly connected to the bottom of the first servo motor 22 and the second servo motor 28 to facilitate fixing the first servo motor 22 and the second servo motor 28, and the first rotating shaft and the second rotating shaft are both rotatably connected to the mounting plate to ensure the stability of rotation.

[0030] In a specific implementation, the movable plate 233 is moved to the side where the fixed plate 232 is close to each other. During this process, the movable plate 233 squeezes the plug block 2381 to overcome the elasticity of the first spring and move upward along the groove. When the slot and the plug block 2381 are vertically aligned, the plug block 2381 moves downward under the action of the first spring to be embedded in the slot, thereby connecting the first slider and the movable plate 233. When separating the movable plate 233 and the first slider, a conical rod is inserted along the pull groove to move the plug block 2381 upward along the slot to separate the plug block 2381 from the movable plate 233, thereby facilitating the separation of the movable plate 233 from the first slider. See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 , the shielding component 24 includes: The rotating ring 243 is arranged on the side wall of the rotating disk 21.

A moving assembly 241 arranged in an annular array and used to drive the retaining ring 244 to move is provided between the rotating ring 243 and the retaining ring 244. In a specific implementation, before the detection mechanism 4 detects the vehicle lamp cover, the moving assembly 241 drives the retaining ring 244 to approach the detection mechanism 4, so that the inner wall of the retaining ring 244 is located outside the vehicle lamp cover, so that during the detection process of the vehicle lamp cover, the splashed fragments of the vehicle lamp cover are blocked in the retaining ring 244, thereby reducing the splashing of the vehicle lamp cover, and facilitating long-term use; The rotating ring 243 and the turntable 21 can rotate relative to each other through the annular slider and the annular groove 242, so that the retaining ring 244 and the turntable 21 can rotate relative to each other, so that during the rotation of the turntable 21, the fragments splashed between the headlight cover, the headlight shell and the retaining ring 244 can fall downward, so that the splashed fragments can fall to the bottom inner wall of the retaining ring 244 to facilitate collection of the fragments.

[0031] See also Fig. 9 and Fig.10 , the mobile component 241 includes: The movable groove 2411 is opened on the outer wall of the rotating ring 243. The top inner wall and the bottom inner wall of the movable groove 2411 are both provided with a second sliding groove 2413. The second sliding groove 2413 is placed inside. A second slider is fixedly provided on the side where the second sliders are close to each other. The connecting plate 2416 is fixedly connected to the inner wall of the retaining ring 244.

[0033] In a specific implementation, when the retaining ring 244 is brought close to the detection mechanism 4, the third electromagnet 2415 and one of the first electromagnets 2414 are started, thereby driving the connecting plate 2416 to move along the second slide groove 2413 and the movable groove 2411 through repulsion, so as to drive the retaining ring 244 to move, so as to collect debris during the detection process, and expose the side of the turntable 21 away from the detection mechanism 4 to avoid affecting the disassembly and assembly of the movable plate 233. When the retaining ring 244 is away from the detection mechanism 4, the second electromagnet 2412 and the other first electromagnet 2414 are started, and the retaining ring 244 is driven to move in the direction through repulsion to avoid affecting the installation of the headlight cover and the headlight shell.

[0034] See also Fig.18 , the detection mechanism 4 includes: The electric slide rail 41 is fixedly arranged on the inner side of the machine body 1 and is located on the side of the base 31 away from the turntable 21. A mechanical arm 42 is fixedly arranged at the sliding end of the electric slide rail 41. A hydraulic rod 43 is fixedly arranged at the free end of the mechanical arm 42. A pressure head 45 is fixedly arranged on the telescopic shaft of the hydraulic rod 43. A stop plate 44 adapted to the stop block 34 is fixedly arranged on the bottom of the telescopic shaft of the hydraulic rod 43.

[0035] In the specific implementation, the positions and angles of the pressure head 45 and the abutment plate 44 are adjusted by the electric slide rail 41 and the mechanical arm 42, so that the hydraulic rod 43 drives the pressure head 45 and the abutment plate 44 to move, thereby squeezing or impacting the headlight cover through the pressure head 45 to test the strength of the headlight cover, and the movement of the abutment plate 44 facilitates the cooperation with the collection assembly to process the debris.

[0036] For example 2, please refer to Figure 2 , Figure 3 and Figure 4 The technical solution of this embodiment is different from that of the first embodiment in that the collection mechanism 3 includes: The base 31 is fixedly arranged on the inner side of the machine body 1 and is located at the bottom of the outer wall of the retaining ring 244. The top of the base 31 is designed to be concave, and the concave part of the top of the base 31 fits with the bottom of the outer wall of the retaining ring 244. Limiting grooves are provided on both sides of the top of the base 31. The inside of the limiting grooves is sleeved with limiting members 35 that move along the inner wall of the limiting grooves. The top of the limiting member 35 is fixedly connected to both sides of the bottom of the scraper 32 to limit the movement of the scraper 32. Guide rods are fixedly arranged on the inner walls of both sides of the limiting groove, and the side walls of the guide rods are sleeved on the inner wall of the limiting member 35. The side walls of the guide rods and the side of the limiting member 35 away from the rotating disk 21 are sleeved with a second spring. The limiting member 35 is designed to be hollow. The scraper 32 is movably arranged in the recessed part at the top of the base 31, and a connecting plate 33 is fixedly provided on the side of the scraper 32 away from the turntable 21. A threaded rod is threadedly connected to the top of the connecting plate 33, and a stop block 34 is fixedly provided on the top of the threaded rod.

A third spring is sleeved on the side wall of one end of the threaded rod at the bottom of the connecting plate 33 and on the top of the protruding part of the threaded rod, and the connecting plate 33 is U-shaped.

[0037] In specific implementation, when the retaining ring 244 is close to the detection mechanism 4, the scraper 32 is always in contact with the lower end of the retaining ring 244 under the action of the second spring, so that during the detection process, the debris in the retaining ring 244 is moved through the inner wall of the retaining ring 244 to the top of the scraper 32 and the top concave part of the base 31, so as to collect the debris in the detection process. When the detection mechanism 4 completes the detection, the telescopic shaft of the hydraulic rod 43 is away from the turntable 21. At this time, the position of the abutment plate 44 is adjusted by the mechanical arm 42, so that the abutment plate 44 drives the abutment block 34 to move when it is away from the turntable 21, thereby driving the connecting plate 33 and the scraper 32 away from the turntable 21, so as to scrape the debris in the top concave part of the base 31 and keep it away from the turntable 21, which is convenient for long-term use. When the pressure head 45 and the stop plate 44 are close to the turntable 21, they are reset by the mechanical arm 42 so that the stop plate 44 is not in contact with the stop block 34. Therefore, under the action of the second spring, the scraper 32 fits with the retaining ring 244 to facilitate the collection of debris. The height of the stop block 34 is adjusted by the threaded rod, and by cooperating with the mechanical arm 42, it is convenient to adapt to different sizes of car headlight covers.
