Description

Technical Field

[0001] This invention relates to the field of American hinge testing technology, specifically to an American hinge testing buffer time machine. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can be made of movable components or foldable materials. Hinges are mostly installed on cabinets and are mainly classified by material into stainless steel hinges and iron hinges. To provide a better experience, hydraulic hinges (also known as damping hinges) have emerged. Their feature is that they provide a buffer function when the cabinet door is closed, minimizing the noise caused by the door colliding with the cabinet body.

[0003] American-style hinges are a type of damping hinge, such as the American-style damping hinge disclosed in patent (publication number: CN109538046A), which includes a hinge cup assembly for hinged assembly of main body via a rotating arm. The hinge cup assembly includes: a hinge cup with a hinge cup cavity, a base with a cavity located in the hinge cup cavity, and a damper disposed in the base and movable relative to the cavity of the base.

[0004] For American hinges, the key indicator for judging their opening and closing performance lies in the stability of the buffer closing time during the closing process. For example, CN209459879U discloses an automatic hinge testing machine, including a base, several hinge fixtures fixed on the base to secure the hinges, a torque detection mechanism, a springback detection mechanism arranged linearly opposite to the torque detection mechanism, and a belt transmission mechanism driving the hinge fixtures. In the above technical solution, when performing torque and springback time tests, it is necessary to wait for the opening and closing process of the tested American hinge to complete before testing the next buffer hinge. In the testing of large batches of American hinges, with common American hinge buffer closing times ranging from 4 to 8 seconds, the waiting time for the American hinge to buffer close significantly affects the testing efficiency. Therefore, a buffer time testing machine for American hinges is proposed to solve the above problems. Summary of the Invention

Detailed Implementation

[0037] 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.

[0038] Please see Figure 1-3This embodiment of an American-style hinge testing buffer time machine includes a frame 1, a test platform 2 fixed to the top surface of the frame 1, a turntable 3 fixed to the bottom inner side of the test platform 2, a table surface 4 fixed to the top of the turntable 3, and the turntable 3 is used to drive the table surface 4 to rotate 90 degrees. Four sets of hinge seats 5 for placing hinges are fixed around the four sides of the upper surface of the table surface 4, with six hinge seats 5 in each set. A conveying mechanism 6 for conveying hinges is provided at the rear end of the top surface of the test platform 2, and a flipping mechanism 7 for flipping hinges is provided at the rear of the frame 1. The test platform 2 is equipped with a clamping mechanism 8 above it for clamping and moving the hinge. The left end of the upper surface of the test platform 2 is equipped with a testing mechanism 9 for quickly testing the hinge. The front end of the test platform 2 is equipped with a non-conforming product unloading mechanism 10 for convenient unloading of non-conforming products. The right end of the upper surface of the test platform 2 is equipped with a conforming product unloading mechanism 11 for convenient unloading of conforming products. Below the conforming product unloading mechanism 11 is a pushing mechanism 12 for driving the hinge to move. The right end of the test platform 2 is fixed with a conforming product unloading cover 13 located below the conforming product unloading mechanism 11.

[0039] It should be noted that the turntable 3 can drive the table 4 to rotate 90 degrees. This is a relatively conventional technical means in the prior art. Therefore, the structure and working principle of the turntable 3 will not be described in detail in this application.

[0040] Please see Figure 4-5 In order to achieve intermittent conveying of the hinge, the conveying mechanism 6 in this embodiment includes a conveying frame 601 fixed to the rear end of the top of the test bench 2. The top of the conveying frame 601 is fixed with two parallel support plates 602. The inner side of the conveying frame 601 is respectively provided with a lifting component 603 and a moving component 604.

[0041] The lifting assembly 603 includes two sets of first sleeves 6031 fixed to the bottom inner side of the conveyor frame 601, with four sleeves in each set. A first slide rod 6032 is slidably connected to the inner side of each sleeve 6031. A lifting plate 6034 is fixed to the top of each slide rod 6032, and a first cylinder 6033 is fixed to the bottom of the lifting plate 6034. The first cylinder 6033 is fixed to the bottom surface of the conveyor frame 601. The moving assembly 604 includes components fixed to... The second cylinder 6041 is located on the lower surface of the lifting plate 6034. The output shaft of the second cylinder 6041 is fixed with a connecting seat 6042. The top of the connecting seat 6042 is fixed with a push plate 6043, and the push plate 6043 is located between two support plates 602. The bottom surface of the push plate 6043 is fixed with multiple first slide blocks 6045. The outer surface of the first slide block 6045 is slidably connected with a first slide rail 6044, and the bottom end of the first slide rail 6044 is fixed to the upper surface of the lifting plate 6034.

[0042] In this embodiment, the conveying mechanism 6 is extended and retracted by the output shaft of the first cylinder 6033, which drives the first slide rod 6032 to slide within the first sleeve 6031. This causes the lifting plate 6034 to drive the moving component 604 to rise and fall, causing the push plate 6043 to move upward and lift the hinges located on the two support plates 602. At the same time, the output shaft of the second cylinder 6041 retracts, causing the push plate 6043 to drive the first slide block 6045 to move horizontally on the first slide rail 6044, thereby driving the hinges on the push plate 6043 to move. After the movement is completed, the output shaft of the first cylinder 6033 retracts, causing the push plate 6043 to drive the hinges to descend as a whole, and the hinges move back to the two support plates 602.

[0043] Please see Figure 6-8 To facilitate the flipping of the hinge, the flipping mechanism 7 in this embodiment includes a base 701 fixed to the rear end of the upper surface of the frame 1. Two support plates 702 are fixed to the top surface of the base 701. A flipping motor 703 is fixed to the left end of the top surface of the base 701.

A pressing plate 706 for pressing material is fixed to the output shaft of the third cylinder 705. A placement seat 707 for placing the hinge is fixed to the rear end of the upper surface of the flipping seat 704.

[0044] In this embodiment, the flipping mechanism 7 is driven by the output shaft of the third cylinder 705 to move the pressure plate 706 and press down on the hinge to prevent the hinge from detaching from the placement seat 707 during the flipping process. Then, the output shaft of the flipping motor 703 drives the flipping seat 704 to rotate 90 degrees, thereby flipping the hinge.

[0045] Please see Figure 9 To facilitate the clamping and movement of the hinge, the clamping mechanism 8 in this embodiment includes multiple first vertical rods 801 fixed to the left and right sides of the rear end of the upper surface of the test platform 2. A mounting plate 802 is fixed to the top of each of the multiple first vertical rods 801. Multiple second sleeves 803 are fixed to the mounting plate 802. Second sliding rods 804 are slidably connected to the inner walls of the second sleeves 803. A fourth cylinder 805 is fixed at the center of the upper surface of the mounting plate 802. A base plate 806 is fixed to the output shaft of the fourth cylinder 805. The front end of the lower surface of the base plate 806 is fixed to... There is a fifth cylinder 807. The left and right ends of the lower surface of the base plate 806 are fixed with second slide rails 808. The outer surface of the second slide rails 808 is slidably connected with second slide blocks 809. The bottom ends of the two sets of second slide blocks 809 are fixed with connecting plates 810. The front and rear ends of the lower surface of the connecting plate 810 are fixed with two sets of clamping cylinders 811.

The output shaft of the fifth cylinder 807 is fixed with the front end of the connecting plate 810.

[0046] In this embodiment, the clamping mechanism 8 is driven by the output shaft of the fourth cylinder 805 to lift the base plate 806, while the output shaft of the fifth cylinder 807 drives the connecting plate 810 to move horizontally in conjunction with the second slide rail 808 and the second slide block 809. One set of clamping cylinders 811 drives the pneumatic grippers 812 to clamp and move the hinge on the support plate 602 to the placement seat 707 on the flipping mechanism 7, and another set of pneumatic grippers 812 moves the hinge that has been flipped on the flipping mechanism 7 to the corresponding hinge seat 5.

The output shaft of the seventh cylinder 911 is fixed to the moving plate 910. A pusher 912 located above the hinge to be tested is fixed to the left end of the moving plate 910.

[0048] In this embodiment, the testing mechanism 9 is driven by the output shaft of the sixth cylinder 902 to raise and lower the detector 904 to the height corresponding to the hinge. The output shaft of the seventh cylinder 911 drives the moving plate 910 to move, so that the pusher 912 pushes the hinge to close. When the hinge is closing, it will contact the detector 904. By judging the buffer time of the hinge closing, it is determined whether the hinge is qualified.

[0049] Please see Figure 12 In order to collect defective hinges, the defective product unloading mechanism 10 in this embodiment includes a defective product unloading cover 1004 fixed to the front end of the test bench 2.

Third sliding rods 1104 are slidably connected to the inner walls of the third sleeves 1103. A lower plate 1105 is fixed to the bottom end of each of the multiple third sliding rods 1104. A ninth cylinder 1106 is fixed at the center of the upper surface of the upper plate 1102, and the output shaft of the ninth cylinder 1106 is fixed to the upper surface of the lower plate 1105. A tenth cylinder 1107 is fixed to the left end of the lower surface of the lower plate 1105. The front and rear ends of the lower surface of the lower plate 1105 are... Each end is fixed with a fourth slide block 1109. The outer surface of the fourth slide block 1109 is slidably connected with a fourth slide rail 1108. The lower surface of the two fourth slide rails 1108 is fixed with a cylinder seat 1110. The output shaft of the tenth cylinder 1107 is fixed to the left end of the cylinder seat 1110.

The output shaft of the twelfth cylinder 1115 is fixed with an auxiliary plate 1116.

[0052] In this embodiment, the qualified product unloading mechanism 11 is driven by the output shaft of the ninth cylinder 1106 to move the lower plate 1105 up and down, the tenth cylinder 1107 to move the cylinder seat 1110 horizontally, the eleventh cylinder 1111 to hook the hanging plate 1112 to hook the qualified hinge and move it above the qualified product unloading cover 13, and finally the output shaft of the twelfth cylinder 1115 to move the auxiliary plate 1116, thereby performing the unloading operation on the qualified hinge located on the hanging plate 1112.

[0053] Please see Figure 15-18To further facilitate the unloading of qualified hinges, the pushing mechanism 12 in this embodiment includes a pushing seat 1201 fixed to the right end of the upper surface of the test bench 2. Both the front and rear ends of the pushing seat 1201 are rotatably connected to a stroke frame 1206. The stroke frame 1206 has a hook-shaped stroke groove 1207.

The output shaft of the fourteenth cylinder 1209 is hinged to the rotating block 1203.

[0054] In this embodiment, the pushing mechanism 12 is raised and lowered by the output shaft of the thirteenth cylinder 1205, which drives the rotating rod 1202 to move upward. At the same time, the stroke frame 1206 rotates along the push seat 1201, and the rotating rod 1202 moves along the stroke groove 1207. Meanwhile, the output shaft of the fourteenth cylinder 1209 extends and retracts, further driving the rotating rod 1202 to move along the stroke groove 1207. This causes the stroke frame 1206 to drive the push plate 1208 to move, so that the push plate 1208 pushes the hinge to perform a flipping action.

[0055] It should be noted that the control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0056] The working principle of the above embodiments is as follows:

[0057] Conveying: An external robotic arm loads the hinge to be inspected onto two support plates 602. Then, the output shaft of the first cylinder 6033 extends and retracts, causing the first slide rod 6032 to slide within the first sleeve 6031. This causes the lifting plate 6034 to move the moving component 604, raising and lowering the push plate 6043 and lifting the hinge on the two support plates 602. Simultaneously, the output shaft of the second cylinder 6041 retracts, causing the push plate 6043 to move the first slide block 6045 horizontally on the first slide rail 6044, thereby moving the hinge on the push plate 6043. After the movement is complete, the output shaft of the first cylinder 6033 retracts, causing the push plate 6043 to lower the hinge as a whole. The hinge then moves back onto the two support plates 602, completing a period of intermittent movement. By repeating the above steps, intermittent conveying of the hinge can be achieved.

[0058] Clamping and moving: When the hinge moves to the end of the support plate 602, the output shaft of the fourth cylinder 805 drives the base plate 806 to move up and down, while the output shaft of the fifth cylinder 807 drives the connecting plate 810 to move horizontally in conjunction with the second slide rail 808 and the second slide block 809. One set of clamping cylinders 811 drives the pneumatic grippers 812 to clamp and move the hinge on the support plate 602 to the placement seat 707 on the flipping mechanism 7, and another set of pneumatic grippers 812 moves the hinge that has been reversed on the flipping mechanism 7 to the corresponding hinge seat 5.

[0059] Flipping: The output shaft of the third cylinder 705 drives the pressure plate 706 to move and press the hinge to prevent the hinge from detaching from the placement seat 707 during the flipping process. Then, the output shaft of the flipping motor 703 drives the flipping seat 704 to rotate 90 degrees, thereby flipping the hinge and opening it. Then, the clamping mechanism 8 clamps and moves the hinge. In this process, the hinge is continuously moved from the conveying mechanism 6 to the flipping mechanism 7, and finally moved to the hinge seat 5.

[0060] Test: The turntable 3 drives the platform 4 to rotate 90 degrees, thereby moving the hinge to be tested to the test mechanism 9. Then, the output shaft of the sixth cylinder 902 drives the detector 904 to rise and fall to the height corresponding to the hinge. The output shaft of the seventh cylinder 911 drives the moving plate 910 to move, so that the pusher 912 pushes the hinge to close. When the hinge is closing, it will contact the detector 904. By judging the buffer time of the hinge closing, the quality of the hinge can be determined.

[0061] Non-conforming product unloading: For non-conforming products, the hinge after testing is rotated again by the turntable 3, so that the hinge is at the non-conforming product unloading mechanism 10. The output shaft of the eighth cylinder 1002 drives the push rod 1003 to move, thereby pushing the hinge on the hinge seat 5 out and moving it to the non-conforming product unloading cover 1004 for recycling.

[0062] Qualified Product Recycling: For qualified products, the turntable 3 rotates again, causing the hinge to move to the push mechanism 12. The output shaft of the thirteenth cylinder 1205 rises and falls, driving the rotating rod 1202 upward. Simultaneously, the stroke frame 1206 rotates along the push seat 1201, and the rotating rod 1202 moves along the stroke groove 1207. At the same time, the output shaft of the fourteenth cylinder 1209 extends and retracts, further driving the rotating rod 1202 to move along the stroke groove 1207. This causes the stroke frame 1206 to drive the push plate 1208 to move, thus... The push plate 1208 pushes the hinge to flip, and then the output shaft of the ninth cylinder 1106 drives the lower plate 1105 to move up and down. The tenth cylinder 1107 drives the cylinder seat 1110 to move horizontally. The eleventh cylinder 1111 drives the hanging plate 1112 to hook the qualified hinge and move it above the qualified product unloading cover 13. Finally, the output shaft of the twelfth cylinder 1115 drives the auxiliary plate 1116 to move, thereby performing the unloading operation on the qualified hinge located on the hanging plate 1112, thus completing the entire testing process.
