The present invention fixes the headlight cover through the headlight shell, thereby facilitating strength detection in line with the actual situation. Compared with the traditional multi-point clamping mechanism, the support effects on the headlight cover at the contact and non-contact positions are different, resulting in different degrees of fragmentation at the clamping position and the unclamped position, affecting the accuracy of strength detection. By making the headlight shell fully contact the edge, i.e., the bending position, of the headlight cover, it is convenient to master the strength at the edge of the headlight cover during the strength detection process, so as to perform intelligent strength detection on the headlight cover.

Description

Technical Field

[0001] The present invention relates to the technical field of strength detection, and specifically to an intelligent strength detection device and method for headlight injection molding dies processing. Background Art

[0002] In headlight detection, the quality of the headlight cover directly affects the lighting effect and service life of the headlight. After the injection-molded parts such as the headlight cover and the headlight housing of the headlight are completed in injection production, it is necessary to randomly inspect the headlight cover to ensure the effect after being put into use.

[0003] A strength detection device for new energy vehicle headlight cover production with the publication number of CN221405197U has a problem proposed in its background art: during the detection process, the strength performance is quite different when the same impact object impacts the same position of the lamp cover with different forces. However, this device fails to perform relevant tests on this situation.

[0004] Based on the existing technologies, the following problems exist:

[0005] The existing headlight cover strength detection devices usually fix the headlight cover in a traditional multi-point clamping manner, resulting in different supporting forces at the positions where the multi-point clamping mechanism contacts and does not contact the headlight cover after impact or extrusion, reducing the detection accuracy, and not conforming to the actual use situation of the headlight cover. During the detection process, when the headlight cover is broken, the existing headlight cover strength detection devices are not convenient for collecting and cleaning the generated fragments, and are not convenient for long-term detection and use. Referring to the above application documents, although it is convenient to perform strength detection on the headlight cover from different angles, when the headlight cover is subjected to strength detection, the supporting forces on the clamped part and the unclamped part are different, affecting the accuracy of strength detection, and not being convenient for collecting and cleaning the fragments generated during the detection process, and not being convenient for long-term use, there are certain deficiencies. To solve the above problems, an intelligent strength detection device and method for headlight injection molding dies processing are proposed. Summary of the Invention

[0038] 1. The present invention fixes the headlight housing through the limit component to fix the headlight cover. After the headlight cover is pressed or impacted, the supporting effect of the headlight cover is in line with the actual situation, so as to facilitate strength detection in line with the actual situation. Compared with the traditional multi-point clamping mechanism, the supporting effects of the positions where the headlight cover is in contact and not in contact are different, resulting in different degrees of fragmentation at the clamped position and the unclamped position, affecting the accuracy of strength detection. By making the headlight housing fully contact the edge, i.e., the bending position, of the headlight cover, it is convenient to master the strength of the edge of the headlight cover during the strength detection process, so as to perform intelligent strength detection on the headlight cover.

[0039] 2.

[0040] 3. The present invention rotates the turntable to facilitate the alignment of the headlight cover fixed by the limit component with the detection mechanism, so as to facilitate the strength detection of the headlight cover in the horizontal position by the detection mechanism, and is convenient for installing multiple headlight covers to improve the efficiency of strength detection. The rotation of the turntable facilitates the fragments during the detection process to fall downward, so as to facilitate the shielding component to collect the fragments.

[0041] 4. The present invention blocks the fragments during the detection process through the shielding component, so as to facilitate the collection of the fragments splashed during the strength detection of the headlight cover and the headlight housing, etc., and is convenient for maintaining the cleanliness of the detection environment.

[0068] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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.

[0069] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 3, An intelligent strength detection device for headlight injection molding molds, including a body 1, further including a fixing mechanism 2 arranged inside the body 1 for fixing the headlight cover, a collection mechanism 3 arranged at the bottom of the fixing mechanism 2 for cleaning debris during the detection process, and a detection mechanism 4 arranged inside the body 1 for detecting the strength of the headlight cover;

[0070] Please refer to Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 16 and Figure 17 , the fixing mechanism 2 includes:

[0071] A turntable 21, rotatably arranged inside the body 1. A shielding component 24 for shielding debris is arranged on the side wall of the turntable 21. A limiting component 23 arranged in an annular array is arranged on the side of the turntable 21 away from the detection mechanism 4. The limiting component 23 includes;

[0072] A fixed seat 231, fixedly arranged on the side of the turntable 21 away from the detection mechanism 4. A moving 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 opened on the side of each moving plate 233 close to the fixed seat 231. A limiting hole 2392 is opened on the inner wall of the limiting groove 2391. A limiting sleeve 239 is sleeved on the inner wall of the limiting groove 2391. A screw rod 26 is sleeved on the inner wall of the limiting sleeve 239;

[0073] A first limiting through groove 235 is opened on the side of the fixed seat 231 close to the turntable 21, so that the screw rod 26 extends to the side of the fixed seat 231 close to the turntable 21 along the first limiting through groove 235.

[0074] The outer surface and the inner surface of the longitudinal section of the limiting sleeve 239 are respectively designed as regular hexagons and circles. The inner wall of the limiting groove 2391 is designed as a regular hexagon and is adapted to the outer wall of the limiting sleeve 239;

[0075] The inner diameter of the limiting groove 2391 is larger than the inner wall diameter of the limiting hole 2392 to limit the limiting sleeve 239 embedded in the limiting groove 2391. After the limiting sleeve 239 is embedded in the limiting groove 2391, the side of the limiting sleeve 239 close to the turntable 21 fits with the side of the fixed seat 231 away from the turntable 21. The fixing mechanism 2 further includes;

[0076] A second limiting through groove 25 is opened in an annular array on the side wall of the turntable 21 and is arranged corresponding to the position of the first limiting through groove 235, so that the screw rod 26 extends to the side of the turntable 21 away from the fixed seat 231 along the first limiting through groove 235 and the second limiting through groove 25.

[0077] The limiting component 23 further includes:

[0078] Fixing plates 232, fixedly arranged on the side of the fixed seat 231 away from the turntable 21 and arranged symmetrically with respect to the center point of the fixed seat 231. On the sides of the fixing plates 232 close to each other, first sliding grooves 234 are formed. The inner walls on both sides of the first sliding grooves 234 extend to the outside of the fixing plates 232. In the first sliding grooves 234, first sliders arranged symmetrically with respect to the center point of the first sliding grooves 234 are placed. On the sides of the first sliders close to each other, disassembly and assembly components 238 are provided. The first sliders are connected to the moving plate 233 through the disassembly and assembly components 238;

[0079] A lead screw 236 is rotatably arranged on the side wall of the fixing plate 232 and extends into the first sliding groove 234. The lead screw 236 is designed as a bidirectional lead screw 236. One end side wall of the lead screw 236 in the first sliding groove 234 is threadedly connected to the first slider, so that the moving plates 233 approach or move away from each other. On the end side walls of the lead screw 236 outside the fixing plate 232, first gears are fixedly sleeved. On the side of the turntable 21 close to the fixed seat 231, a rotating rod is rotatably arranged. On the side wall at both ends of the rotating rod, a second gear and a bevel gear 237 are fixedly sleeved respectively. The two side parts of the second gear are meshed with the two first gears respectively.

[0080] During 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 through groove 235 and the second limiting through groove 25 to the side of the turntable 21 close to the detection mechanism 4. Then, the screw 26 is rotated, and the screw hole installation part of the lamp housing is connected to the side wall of one end of the screw 26 on the side of 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 prior art and will not be elaborated here. Thus, the lamp cover is connected to the lamp housing to facilitate the fixing of the lamp cover. And after the lamp cover and the lamp housing are connected, the strength of the lamp cover is detected, which is convenient for the subsequent detection mechanism 4 to detect the strength of the lamp cover. And when the strength detection is carried out, it is convenient to master the strength at the connection between the lamp cover and the lamp housing, so as to facilitate mastering the stability of the connection between the lamp cover and the lamp housing after the lamp cover is impacted or pressed;

[0081] When performing strength detection on lamp housings of different sizes, it is first necessary to install the corresponding lamp shells. For this purpose, by rotating the lead screw 236, the first slider is driven to approach or move away from each other along the first chute 234 during the rotation of the lead screw 236, thereby adjusting the position of the moving plate 233 to be applicable to lamp shells of different sizes, so as to facilitate the fixing of lamp housings of different sizes. Moreover, different lamp shells use different screws 26. For this reason, the moving plate 233 is separated from the first slider through the disassembly and assembly component 238, so that the moving plate 233 is disengaged from the side where the fixed plate 232 approaches each other, so as to take out the limit sleeve 239 from the limit groove 2391, thereby replacing the limit sleeve 239 corresponding to the lamp shell to limit the screw 26, avoiding the situation of fixing looseness due to the gap between them after the screw 26 passes through the limit sleeve 239, or the situation where the screw 26 cannot pass through the inner wall of the limit sleeve 239, so as to be applicable to lamp shells of different sizes and thus fix lamp housings of different sizes;

[0082] By embedding the limit sleeve 239 into the moving plate 233 along the limit groove 2391, and by making the inner wall diameter of the limit hole 2392 smaller than the inner diameter of the limit groove 2391, so that after the limit sleeve 239 is embedded into the limit groove 2391, the side wall of the moving plate 233 located outside the limit hole 2392 limits the limit sleeve 239. And when the moving plate 233 is connected to the first slider through the disassembly and assembly component 238, the limit sleeve 239 fits against the side of the fixed seat 231 away from the turntable 21, thereby limiting both ends of the limit sleeve 239, facilitating the replacement of the limit sleeve 239 while ensuring its stability;

[0083] By designing the inner wall of the limit sleeve 239 to be circular, the rotation of the screw 26 is not affected when the screw 26 passes through the inner walls of the limit hole 2392 and the limit sleeve 239, which is convenient for fixing the lamp shell, so as to facilitate the actual fixing of the lamp housing. Moreover, the outer wall of the limit sleeve 239 fits against the inner wall of the limit groove 2391, and both are designed to be regular hexagons, thereby limiting the limit sleeve 239 to prevent it from rotating and improving stability;

[0084] The lamp housing is used to fix the lamp cover. Since the bent part of the side wall of the lamp cover is in full contact with the lamp housing, after the lamp cover is pressed or impacted, the supporting effect on the lamp cover conforms to the actual situation, which is convenient for carrying out strength detection according to the actual situation. Moreover, compared with the traditional method of fixing the lamp cover by multi-point clamping for strength detection, after being pressed or impacted during the detection process, the supporting effects of the traditional multi-point clamping mechanism on the lamp cover at the contact and non-contact positions with the lamp cover are different, resulting in different degrees of fragmentation at the clamped position and the unclamped position, affecting the accuracy of strength detection. And by making the lamp housing in full contact with the edge, i.e., the bent position, of the lamp cover, it is convenient to master the strength of the edge of the lamp cover during the strength detection process, so as to perform intelligent strength detection on the lamp cover;

[0085] By rotating the turntable 21, it is convenient to make the lamp cover fixed by the limiting component 23 correspond to the position of the detection mechanism 4, so as to facilitate the detection mechanism 4 to perform strength detection on the lamp cover in the horizontal position, and it is also convenient to install multiple lamp covers, improving the efficiency of strength detection. And by rotating the turntable 21, it is convenient for the fragments during the detection process to fall downward, so as to facilitate the shielding component 24 to collect them.

[0086] The fixing mechanism 2 further includes:

[0087] The first servo motor 22 is fixedly arranged inside 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 the end of the first rotating shaft away from the first servo motor 22 is fixedly connected to the turntable 21, so that the first servo motor 22 drives the turntable 21 to rotate;

[0088] The bevel gear disk 27 is rotatably arranged at the center of the side of the turntable 21 close to the fixed seat 231, and the bevel gear disk 27 meshes with the bevel gear 237. The inner wall of the bevel gear disk 27 is fixedly sleeved with a sleeve rod 29. The sleeve rod 29 is designed to be hollow. 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 inside the machine body 1. The output shaft of the second servo motor 28 is fixedly provided with a second rotating shaft. Transmission gears that mesh with each other are fixedly arranged on the side wall of the second rotating shaft and the outer wall of the sleeve rod 29, so that the second servo motor 28 drives the bevel gear disk 27 to rotate.

[0089] During specific implementation, start the first servo motor 22. The output shaft of the first servo motor 22 drives the first rotating shaft to rotate through the coupling. 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 meshes and transmits along the bevel gear disk 27. At this time, the second servo motor 28 can be rotated to avoid movement obstacles of the first servo motor 22 and the second servo motor 28, and it is convenient to adjust the position of the moving plate 233;

[0090] Start the second servo motor 28. The second servo motor 28 drives the second rotating shaft to rotate through a coupling. The second rotating shaft drives the sleeve rod 29 to rotate through a transmission gear. The sleeve rod 29 drives the bevel gear disk 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 lead screw 236 to rotate, facilitating the synchronous adjustment of the positions of multiple moving plates 233 and being convenient for actual adjustment and use. Through the meshing direction of the bevel gear 237 and the bevel gear disk 27 and the thread connection direction between the lead screw 236 and the first slider, it is convenient to make the moving plates 233 approach or move away from each other, thus facilitating actual operation;

[0091] An installation plate is fixedly arranged inside the machine body 1. The top of the installation plate is fixedly connected to the bottoms of the first servo motor 22 and the second servo motor 28, facilitating the fixation of the first servo motor 22 and the second servo motor 28. Moreover, both the first rotating shaft and the second rotating shaft are rotatably connected to the installation plate, ensuring the stability of rotation.

[0092] Please refer to Figure 14 and Figure 15 , the disassembly and assembly component 238 includes:

[0093] The insertion block 2381 is movably arranged on one side where the first sliders approach each other. Grooves are formed on one side where the first sliders approach each other. The side wall of the insertion block 2381 is sleeved in the groove. A plug rod 2383 is fixedly arranged on the top of the insertion block 2381;

[0094] The fixing ring 2382 is fixedly sleeved on the inner wall of the groove. The inner wall of the fixing ring 2382 is sleeved on the side wall of the plug rod 2383. A first spring is sleeved on the side wall of the plug rod 2383 and on the side where the insertion block 2381 and the fixing ring 2382 approach each other. One end of the plug rod 2383 located at the top of the fixing ring 2382 is designed to protrude outward, so that the protruding part at the top of the plug rod 2383 is in a stop fit with the fixing ring 2382, thereby restricting the separation of the plug rod 2383 from the fixing ring 2382. Slots adapted to the insertion block 2381 are formed on the top and bottom of the moving plate 233. A dial groove communicating with the slot is formed on the side wall of the moving plate 233. The top and bottom of the moving plate 233 are respectively attached to one side where the fixing plates 232 approach each other.

[0095] In specific implementation, the moving plate 233 is moved to the side where the fixing plate 232 is closer to each other. During this process, the moving plate 233 squeezes the insertion block 2381 to move upward along the groove against the elasticity of the first spring. When the slot is vertically aligned with the insertion block 2381, the insertion block 2381 moves downward under the action of the first spring to be embedded in the slot, thereby connecting the first slider and the moving plate 233. When separating the moving plate 233 and the first slider, a conical rod is inserted along the dial groove, etc., so that the insertion block 2381 moves upward in the slot, so that the insertion block 2381 is separated from the moving plate 233, thereby facilitating the separation of the moving plate 233 from the first slider;

[0096] Please refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , the shielding assembly 24 includes:

[0097] A rotating ring 243 is provided on the side wall of the turntable 21. An annular chute 242 is provided on the side wall of the turntable 21. An annular slider is placed inside the annular chute 242. The outer wall of the annular slider is fixedly connected to the inner wall of the rotating ring 243. A retaining ring 244 is movably provided on the outer wall of the rotating ring 243. 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.

[0098] In specific implementation, before the detection mechanism 4 detects the 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 lamp cover. During the detection of the lamp cover, the splashed fragments such as the lamp cover are blocked inside the retaining ring 244, reducing the splashing of the lamp cover everywhere and facilitating long-term use;

[0099] Through the annular slider and the annular chute 242, the rotating ring 243 and the turntable 21 can rotate relative to each other, so that the retaining ring 244 and the turntable 21 can rotate relative to each other. During the rotation of the turntable 21, it is convenient for the fragments splashed between the lamp cover, the lamp housing and the retaining ring 244 to fall downward, so that it is convenient for the splashed fragments to fall to the bottom inner wall of the retaining ring 244, so as to facilitate the collection of the fragments.

[0100] Please refer to Figure 9 and Figure 10 , the moving assembly 241 includes:

[0101] A moving groove 2411 is opened on the outer wall of the rotating ring 243. Second chutes 2413 are opened on the top inner wall and the bottom inner wall of the moving groove 2411. Second sliders are placed inside the second chutes 2413. A connecting plate 2416 is fixedly provided on the side of the second sliders close to each other. The connecting plate 2416 is fixedly connected to the inner wall of the retaining ring 244.

[0102] The moving component 241 further includes:

[0103] The first electromagnet 2414 is fixedly arranged on both sides of the connecting plate 2416. The second electromagnet 2412 and the third electromagnet 2415 are respectively fixedly arranged on the inner walls of both sides of the moving groove 2411. The sides of the second electromagnet 2412 and one of the first electromagnets 2414 that are close to each other are the same-pole magnetic poles, and the sides of the third electromagnet 2415 and the other first electromagnet 2414 that are close to each other are the same-pole magnetic poles.

[0104] In specific implementation, when the retaining ring 244 is moved closer to the detection mechanism 4, the third electromagnet 2415 and one of the first electromagnets 2414 are started, so as to drive the connecting plate 2416 to move along the second sliding groove 2413 and the moving groove 2411 through the repulsive force, so as to drive the retaining ring 244 to move, which is convenient for collecting the debris during the detection process, and the side of the turntable 21 away from the detection mechanism 4 is exposed, avoiding affecting the disassembly and assembly of the moving plate 233. When the retaining ring 244 moves 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 opposite direction through the repulsive force, avoiding affecting the installation of the lamp cover and the lamp housing.

[0105] Please refer to Figure 18 , the detection mechanism 4 includes:

[0106] The electric slide rail 41 is fixedly arranged inside the machine body 1 and is located on the side of the base 31 away from the turntable 21. The sliding end of the electric slide rail 41 is fixedly provided with a robotic arm 42. The free end of the robotic arm 42 is fixedly provided with a hydraulic rod 43. The telescopic shaft of the hydraulic rod 43 is fixedly provided with a pressing head 45. The bottom of the telescopic shaft of the hydraulic rod 43 is fixedly provided with a pressing plate 44 adapted to the abutting block 34.

[0107] In specific implementation, the positions and angles of the pressing head 45 and the pressing plate 44 are adjusted through the electric slide rail 41 and the robotic arm 42, which is convenient for the hydraulic rod 43 to drive the pressing head 45 and the pressing plate 44 to move, so as to squeeze or impact the lamp cover through the pressing head 45, etc., so as to perform strength detection on the lamp cover, and through the movement of the pressing plate 44, it is convenient to cooperate with the collection component to process the debris.

[0108] Embodiment 2, please refer to Figure 2 , Figure 3 and Figure 4 , the different technical solution of this embodiment compared with Embodiment 1 is that the collection mechanism 3 includes:

[0109] The base 31 is fixedly arranged inside 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 at the top of the base 31 fits with the bottom of the outer wall of the retaining ring 244. Limited position grooves are provided on both sides of the top of the base 31, and limited position members 35 that move along the inner walls of the limited position grooves are sleeved inside the limited position grooves. The tops of the limited position members 35 are fixedly connected to both sides of the bottom of the scraping plate 32 to limit the movement of the scraping plate 32. Guide rods are fixedly arranged on both inner walls of the limited position grooves, and the side walls of the guide rods are sleeved inside the inner walls of the limited position members 35. A second spring is sleeved on the side wall of the guide rod and on the side of the limited position member 35 away from the turntable 21. The limited position member 35 is designed to be hollow;

[0110] The scraping plate 32 is movably arranged in the concave part at the top of the base 31. A connecting plate 33 is fixedly arranged on the side of the scraping plate 32 away from the turntable 21. A threaded rod is threadedly connected to the top of the connecting plate 33. A resisting block 34 is fixedly arranged at the top of the threaded rod. The bottom of the threaded rod extends to the bottom of the connecting plate 33, and one end of the threaded rod at the bottom of the connecting plate 33 protrudes outward. A third spring is sleeved on the side wall of the threaded rod at the bottom of the connecting plate 33 and on the top of the protruding part of the threaded rod. The connecting plate 33 is designed in a U shape.

[0111] During specific implementation, when the retaining ring 244 approaches the detection mechanism 4, the scraping plate 32 always fits with the lower end of the retaining ring 244 under the action of the second spring. Thus, during the detection process, the debris inside the retaining ring 244 moves along the inner wall of the retaining ring 244 to the top of the scraping plate 32 and the concave part at the top of the base 31, facilitating the collection of debris during the detection process. After the detection mechanism 4 finishes detection, the telescopic shaft of the hydraulic rod 43 moves away from the turntable 21. At this time, the position of the pressing plate 44 is adjusted through the robotic arm 42, so that when the pressing plate 44 moves away from the turntable 21, it drives the resisting block 34 to move, thereby driving the connecting plate 33 and the scraping plate 32 to move away from the turntable 21, scraping the debris in the concave part at the top of the base 31, etc., to make it move away from the turntable 21, facilitating long-term use;

[0112] When the pressing head 45 and the pressing plate 44 approach the turntable 21, the robotic arm 42 is reset so that the pressing plate 44 does not contact the resisting block 34. Thus, under the action of the second spring, the scraping plate 32 fits with the retaining ring 244, facilitating the collection of debris. The height of the resisting block 34 is adjusted through the threaded rod, and in cooperation with the robotic arm 42, it is convenient to adapt to the use of lamp covers of different sizes.

[0113] The electronic devices such as the first servo motor 22 of the present invention are all connected to an external power supply and a controller through wires for actual control and use. This is prior art and will not be elaborated here.
