Description

Technical Field

[0001] This invention belongs to the field of automotive sun visor technology, and particularly relates to a sun visor pivot assembly and testing machine. Background Technology

[0002] A car sun visor is installed on the windshield of the driver's / passenger's cabin to block the glare of the sun. It can be folded down to block sunlight when in use and folded up to fit flush against the roof when not in use. Sun visors are typically made of knitted fabrics, imitation suede, PVC film, or other materials covered with plastic, EPP, or PU foam.

[0003] Currently, most automotive sun visors are assembled manually between the panel and the pivot, and then sent to specialized testing equipment to test the product performance. This production method is inefficient and highly dependent on manual labor. There is a lack of automated equipment that integrates installation and testing, making it difficult to improve production efficiency. Therefore, there is an urgent need for a sun visor pivot assembly and testing machine to solve this problem. Summary of the Invention

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Reference Figures 1 to 11 The present invention discloses a sunshade pivot assembly and testing machine, comprising: a frame structure and a sunshade transfer mechanism 1, a flipping test mechanism 2, a pivot moving mechanism 4 and a sunshade fixing mechanism 5 installed in the frame structure;

[0058] The sun visor fixing mechanism 5 is provided with a fixing part for installing the sun visor body and a first moving part for adjusting the position of the fixing part. The first moving part moves the fixing part to the assembly position.

[0059] The rotating shaft moving mechanism 4 is located on one side of the sunshade fixing mechanism 5. The rotating shaft moving mechanism 4 is provided with a mounting part for installing the sunshade shaft and a horizontal rotating part for adjusting the position of the mounting part. After the mounting part fixes the sunshade shaft, the horizontal rotating part rotates the sunshade shaft back and forth and pushes it into the rotating shaft mounting position of the sunshade.

[0060] The sun visor transfer mechanism 1 is located on the other side of the sun visor fixing mechanism 5. The sun visor transfer mechanism 1 is provided with a clamping part and a second moving part. The clamping part is used to clamp the assembled sun visor as a whole, and the second moving part allows the clamping part to switch between the assembly position and the detection position.

[0061] The flip test mechanism 2 is located on the side of the sunshade transfer mechanism 1 away from the sunshade fixing mechanism 5. The flip test mechanism 2 is equipped with a detection part, which is located at the detection position. The detection part is used to detect the overall physical performance of the sunshade that has been moved to the detection position.

[0062] During operation, workers install the sun visor body onto the fixing part and the sun visor shaft onto the mounting part. The first moving part of the sun visor fixing mechanism 5 drives the fixing part to move to the preset assembly position. Simultaneously, the rotating shaft moving mechanism 4 located on one side starts working. The mounting part moves the fixed sun visor shaft, and then the horizontal rotating part drives the mounting part to smoothly push the shaft into the rotating shaft mounting hole fixed on the sun visor fixing mechanism 5 during reciprocating rotation, completing the precision pressing and initial engagement of the rotating shaft. After assembly, the sun visor transfer mechanism 1 located on the other side of the sun visor fixing mechanism 5 immediately activates. Its clamping part accurately clamps the assembled sun visor shaft, and then the second moving part drives the clamping part to transfer the product from the assembly position to the inspection position. At this position, the inspection part of the flipping test mechanism 2 is in place, automatically testing the physical properties of the delivered sun visor, such as flipping torque, damping smoothness, and upper pressure. The entire process is integrated and carried out in an orderly manner within the frame structure. Its core effect lies in realizing the fully automated integration of sun visor hinge assembly and performance testing. Through the coordination of sun visor fixing mechanism 5 and hinge moving mechanism 4, the accuracy and consistency of hinge assembly are ensured. Through the connection of sun visor transfer mechanism 1, seamless flow between assembly and testing stations is realized, improving efficiency. Finally, the flipping testing mechanism 2 completes the quality inspection closed loop, thereby significantly improving production cycle time, product qualification rate and process stability, and greatly reducing the intensity of manual operation and intervention.

[0063] The frame structure includes a base 3 and a top frame 8, which are fixed to the base 3. A display screen and an alarm are installed on the top frame 8. The display screen is used to display test data, and the alarm will sound an audible and visual alarm when a defective product is detected. The sunshade transfer mechanism 1, the flip test mechanism 2, the rotating shaft moving mechanism 4, and the sunshade fixing mechanism 5 are all installed on the base 3. The base 3 is equipped with a discharge ramp 6 and an electrical compartment 7. The electrical compartment 7 is used to house electrical equipment such as controllers and power adapters. The inlet end of the discharge ramp 6 corresponds to and is connected to the outlet end of the test position. After the movable end of the sunshade transfer mechanism 1 moves the entire sunshade to the test position, and the flip test mechanism 2 completes the test, the entire sunshade is released directly at the test position, causing it to fall onto the discharge ramp 6, thus outputting a qualified product.

[0064] As an optional implementation, the sunshade transfer mechanism 1 further includes a first base 106, the fixed end of the second moving part is fixedly connected to the first base 106, and the first base 106 is fixed to the frame structure;

[0065] The second moving part includes:

[0066] The fixing plate 103 is fixedly connected to the first base 106;

[0067] The sliding mounting plate 102 is horizontally slidably fitted with the fixed plate 103;

[0068] The fixed end of the cable chain 101 is fixedly connected to the fixed plate 103, and the movable end of the cable chain 101 is fixedly connected to the sliding mounting plate 102.

[0069] The lifting plate 110 is vertically slidably engaged with the sliding mounting plate 102.

[0070] The fixed end of the first telescopic cylinder 107 is fixedly connected to the sliding mounting plate 102, and the movable end of the first telescopic cylinder 107 is fixedly connected to the lifting plate 110.

[0071] The bottom ends of the lifting plate 110 are respectively fixed with the fixed ends of the first gripper 105 and the second gripper 111.

[0072] In the sun visor rotating shaft assembly and testing machine, after the second moving part of the sun visor transfer mechanism 1 is activated, its fixed plate 103 serves as a basic support, driving the sliding mounting plate 102 to slide horizontally, realizing the lateral transfer from the assembly station to the testing station. Simultaneously, the drag chain 101 extends and retracts synchronously during the sliding process, effectively protecting internal cables or air pipes. Upon reaching the testing station, the first telescopic cylinder 107 actuates, pushing the lifting plate 110 downwards vertically, allowing the first gripper 105 and the second gripper 111, fixed at the bottom of the lifting plate, to accurately clamp the assembled sun visor. Subsequently, the first telescopic cylinder 107 rises, and the second moving part moves in the opposite direction, smoothly transporting the product back. The entire process, through a combination of horizontal sliding and vertical lifting motion, achieves rapid and precise transfer of the sun visor between stations, and the arrangement of the drag chain 101 ensures the reliability and lifespan of the mechanism's movement.

[0073] As an optional implementation, a second slide rail 108 and a slide rod 109 are fixed on the fixed plate 103, and the sliding mounting plate 102 slides in cooperation with the fixed plate 103 through the second slide rail 108 and the slide rod 109.

[0074] A first slide rail 104 is fixedly connected to the sliding mounting plate 102, and the lifting plate 110 slides vertically with the sliding mounting plate 102 through the first slide rail 104.

[0075] The second slide rail 108 and the slide rod 109 guide the sliding mounting plate 102 to slide horizontally, while the first slide rail 104 guides the lifting plate 110 to slide vertically. Together, they achieve a smooth and precise composite movement of the gripper, improving the accuracy and reliability of the transfer positioning.

[0076] As an optional implementation, the flipping test mechanism 2 also includes:

[0077] The second base 203 is fixed to the frame structure;

[0078] The first reducer 202 has its fixed end fixedly connected to the second base 203, and its output shaft is fixedly connected to the fixed end of the detection unit.

[0079] The first motor 201 is fixed at its fixed end to the second base 203, and the output shaft of the first motor 201 is shaft-connected to the input shaft of the first reducer 202.

[0080] After the first motor 201 starts, its output power is adjusted in speed and torque via the first reducer 202, thereby driving the detection unit fixed to it to perform a precise flipping action to conduct physical performance testing on the entire sun visor; the entire transmission mechanism is stably supported by the second base 203. This structure ensures the smoothness of power transmission and the accuracy of angle control during the testing process.

[0081] As an optional implementation, the detection unit includes a gripper base 206, which is coaxially fixed to the output shaft of the first reducer 202. The gripper base 206 is provided with two third grippers 205, which are slidably engaged with the gripper base 206. A driving member is also provided, which causes the two third grippers 205 to move closer or further apart. A first pressure sensor 204 is fixed on the third gripper 205, and the first pressure sensor 204 is located between the two third grippers 205.

[0082] It also includes a pressure detection mechanism 9, which is fixed inside the frame structure. The pressure detection mechanism 9 is used to detect the pressure generated by the sun visor on the pressure detection mechanism 9 after the third gripper 205 flips the sun visor body and the third gripper 205 is released.

[0083] The driving components are a counter-threaded screw and a motor. The two ends of the counter-threaded screw are respectively threaded into the corresponding third jaws 205. The third jaws 205 are slidably engaged with the jaw base 206. The fixed end of the motor is fixed to the jaw base 206. The output shaft of the motor is coaxially fixed to the counter-threaded screw.

[0084] During the testing phase, the driving mechanism of the testing unit is activated, causing the opposing threaded screws to rotate. This drives the two third grippers 205 to slide synchronously towards or away from each other on the gripper base 206, precisely gripping or releasing the entire sun visor transported to the testing position by the sun visor transfer mechanism 1. Subsequently, the first reducer 202 drives the gripper base 206 and the gripped sun visor to perform a flipping action, while the first pressure sensor 204 monitors the gripping force in real time. After the flipping test is completed, the third grippers 205 are released, and the sun visor body naturally returns to its original position. At this time, the pressure detection mechanism 9, located within the frame structure, detects the pressure exerted on it by the sun visor body in its free state. This design achieves dual automated detection of the sun visor's flipping performance and its self-stability after resetting. Through the coordinated data acquisition of the first pressure sensor 204 and the pressure detection mechanism 9, the accuracy of the product's torque adaptability and durability assessment is effectively improved.

[0085] As an optional implementation, the pressure detection mechanism 9 includes a fixing member 901, which is fixed to the frame structure. The fixing member 901 is fixedly connected to a fixing platform 902, and a pressure sensor head 903 is provided on the fixing platform 902.

[0086] After the sun visor completes the flipping test in the flipping test mechanism 2 and is released by the third gripper 205, the visor naturally falls back, generating pressure on the pressure sensor head 903 set on the fixed platform 902. This pressure data is collected in real time to evaluate the sun visor's restoring force in its free state. The entire pressure detection mechanism 9 is securely installed through the fastener 901, ensuring the stability of the testing process and the accuracy of the results.

[0087] As an optional implementation, the rotating shaft moving mechanism 4 also includes a third base 406, which is fixed to the frame structure. The fixed end of the horizontally rotating part is fixedly connected to the third base 406, and the movable end of the horizontally rotating part is fixedly connected to the mounting part.

[0088] The horizontal rotating part includes a second telescopic cylinder 404, the fixed end of which is fixedly connected to a third base 406. The movable end of the second telescopic cylinder 404 slides with the third base 406 via a third slide rail 401. The movable end of the second telescopic cylinder 404 is fixedly connected to the fixed end of a second reducer 405. The input shaft of the second reducer 405 is shaft-connected to the output shaft of a second motor 403. The fixed end of the second motor 403 is fixedly connected to the movable end of the second telescopic cylinder 404. The output shaft of the second reducer 405 is fixedly connected to the mounting part.

[0089] The mounting section includes a shaft fixing mold 402, which is coaxially fixed to the output shaft of the second reducer 405.

[0090] When the rotating shaft moving mechanism 4 starts working, the sun visor shaft is already installed on the rotating shaft fixing mold 402. The piston rod of the second telescopic cylinder 404 extends, pushing its movable end and the entire installation to move smoothly horizontally along the third slide rail 401 towards the sun visor fixing mechanism 5, achieving precise horizontal feeding. At the same time, the second motor 403 starts, and the output power, after being adjusted and increased in torque by the second reducer 405, drives the rotating shaft fixing mold 402 and the sun visor shaft on it to rotate together. This combined motion allows the shaft to be precisely inserted into the rotating shaft mounting hole of the sun visor body while rotating at a uniform speed, completing the precision pressing. The second motor 403 and the second reducer 405 are both fixed to the movable end of the second telescopic cylinder 404, and are stably supported by the third base 406. This design, through the coordinated action of the horizontally rotating part, combines rotational motion and linear propulsion, ensuring the centering of the shaft assembly, the uniformity of the meshing depth, and the stability of the operation process.

[0091] As an optional implementation, the sunshade fixing mechanism 5 further includes a fourth base 510, which is fixed to the frame structure. The fixed end of the first movable part is fixedly connected to the fourth base 510, and the movable end of the first movable part is connected to the fixed part.

[0092] The fourth base 510 provides a stable mounting foundation for the first moving part, ensuring that its driven fixed part remains stable during the movement to the assembly position, thereby establishing a precise positioning reference for the subsequent shaft press-fitting process.

[0093] As an optional implementation, the first moving part includes:

[0094] The sliding seat 505 and the fourth base 510 are slidably engaged. The fourth base 510 is fixed with a fourth slide rail 514. A slider 509 slides on the fourth slide rail 514 and is fixed to the sliding seat 505.

[0095] The third telescopic cylinder 504 has its fixed end fixedly connected to the fourth base 510, and its movable end fixedly connected to the sliding seat 505. The fixed part is connected to the sliding seat 505.

[0096] When the first moving part is working, the movable end of the third telescopic cylinder 504 extends or retracts, driving the sliding seat 505 to slide horizontally along the fourth slide rail 514 fixed on the fourth base 510; the slider 509 is precisely matched with the fourth slide rail 514, providing smooth movement guidance and support for the sliding seat 505. Through the precise stroke control of the third telescopic cylinder 504, the fixed part connected to the sliding seat 505 is moved to the preset assembly position, thereby ensuring accurate positioning of the sunshade panel during assembly and providing a stable reference for pressing in the rotating shaft.

[0097] As an optional implementation, the fixing part includes:

[0098] The sunshade mold 501 has a sunshade plate body groove. The sunshade mold 501 is used to put the sunshade plate body. The sunshade mold 501 is fixed with a mold mounting seat 507. The mold mounting seat 507 is fixed with a sliding seat 505.

[0099] The fixed block 511 is slidably mounted on the sliding seat 505. The movable end of the fifth telescopic cylinder 508 is fixedly connected to the fixed block 511, and the fixed end of the fifth telescopic cylinder 508 is fixedly connected to the sliding seat 505.

[0100] The lifting base 503 is fixed to the fixed block 511. The fixed end of the fourth telescopic cylinder 506 is fixedly connected to the lifting base 503. The movable end of the fourth telescopic cylinder 506 is fixedly connected to the pressing block 502. The pressing block 502 and the lifting base 503 slide vertically together.

[0101] It also includes two rotary telescopic cylinders 513. The fixed ends of the two rotary telescopic cylinders 513 are symmetrically fixed to the fourth base 510. The movable ends of the rotary telescopic cylinders 513 are fixed to pressure claws 512. When the movable ends of the rotary telescopic cylinders 513 retract, the pressure claws 512 are made vertical and pressed against the outside of the sunshade mold 501.

[0102] In the sun visor shaft assembly and testing machine, the operator first places the sun visor body into the groove of the sun visor mold 501 for initial positioning. Then, two rotary telescopic cylinders 513 are activated; their movable ends first rotate to adjust the angle, then retract linearly, causing the pressure claws 512 fixed to their movable ends to press vertically downwards, pressing them firmly against the sun visor mold 501 from the outside, achieving initial peripheral fixation of the mold and the visor body. Next, the fifth telescopic cylinder 508 actuates, driving the fixing block 511 to slide on the sliding seat 505, thereby adjusting the horizontal position of the lifting base 503 fixed thereto. Finally, the fourth telescopic cylinder 506 extends, pushing the lowering block 502 vertically down along the lifting base 503, applying downward pressure to the sun visor body already placed in the mold, completing the final precise clamping. The mold mounting seat 507 ensures a stable connection between the sun visor mold 501 and the sliding seat 505. The fixing part achieves non-direct contact locking of the outside of the mold through the cooperation of the rotary telescopic cylinder 513 and the pressure claw 512.
