[0035] Example 1

[0036] like Figure 1 , Figure 2 , Figure 3As shown, the unloading device for lock testing in this embodiment includes a divider turntable 1 and an unloading rack 2 installed on the testing table 3. The divider turntable 1 achieves continuous transfer of locks through the cooperation of a fixed inner plate 11 and a movable outer plate 12. The movable outer plate 12 has at least one unloading station 14, and a fixed fixture 13 is provided at the unloading station 14. At least 6 fixed fixtures 13 are evenly distributed on the movable outer plate 12. The fixed fixture is a long strip block with spaced cutouts. It has fixed limiting blocks at both ends that fit into the lock to be tested, and limiting posts and fixing holes for connection around the perimeter. It is used to fix the lock to be tested in the horizontal direction. There is a height difference between the middle and the sides of the fixed fixture. In this embodiment, there are 8 fixed fixtures distributed at intervals. The unloading station 14 is provided with an unloading rack 2 at the corresponding testing table 3. The unloading rack 2 is constructed of aluminum profiles, and its height can be adjusted by adjusting the feet to adapt to the testing requirements of different specifications of locks.

When the lock is detected, the conveyor line is opened and the counting function is triggered. In conjunction with the PLC control system, real-time statistics of production data are realized.

[0037] Example 2

[0038] like Figure 4 , Figure 5 , Figure 6As shown, after the servo motor 51 of the servo rotating part 5 is rigidly connected to the reducer 52, it is fixed to the steel plate fixing plate 53 by M8 hexagon socket bolts. The servo motor 51 is a product of Mitsubishi Corporation. The fixing column 54 is made of chrome-plated round steel and the fixing plate 53 is connected to the fixing seat 55 by four M10 bolts. One end of the fixing seat 55 is fixedly connected to the unloading rack 2 by the clip protrusion 551. The other end of the fixing seat is equipped with a seated bearing 56. The lower end of the seated bearing 56 is connected to a rotating plate 57 that follows the rotation. The rotating plate 57 is made of aviation aluminum alloy to ensure a balance between lightweight and rigidity.

[0039] The reducer 52 is connected to the bearing 56 via a coupling 510. The coupling 510 is a plum blossom-shaped flexible coupling, which compensates for installation errors and reduces vibration and noise. An annular protrusion 511 is provided between the coupling 510 and the bearing 56. A set of limit stops 512 are provided on the fixed seat 55 to limit the rotation of the annular protrusion within 150 degrees, which strictly limits the rotation angle. The annular protrusion 511 is distributed at a right angle to the rotating plate 57 as a calibration mark, which improves the repeatability control accuracy of the material handling part 6.

[0040] The rotating plate 57 has a vertical connecting plate 58 at its end. The connecting plate and the rotating plate are connected by a right-angle piece 59. The connecting plate is connected to the material handling part 6.

[0041] Example 3

[0042] like Figure 7 As shown, the material handling unit 6 includes a lifting cylinder 61 mounted on the other side of the connecting plate. A first limiting block 62 is fixed to the bottom side of the lifting cylinder 61, and a strip-shaped slider 63 is fixed to the outside of the lifting cylinder 61. The strip-shaped slider 63 is fixed on a sliding plate 64 with a matching groove. A second limiting block 65 is provided on the side of the sliding plate, which is perpendicular to the first limiting block 62. The lifting cylinder 61 is made of SMC brand, and with the precision guide rail structure of the strip-shaped slider 63 and the sliding plate 64, vertical lifting without swaying is achieved. The first limiting block 62 and the second limiting block 65 are made of wear-resistant cast iron, and the spacing is finely adjusted by bolts to ensure the consistency of the lifting limit position. The end of the movable rod 67 of the lifting cylinder 61 is engaged in a fixed block 68 with a matching groove. The movable rod 67 and the sliding plate 64 are parallel to each other and fixed on the fixed block.

[0043] The slide plate 64 is fixed to the cylinder fixing block 69 of the gripper cylinder 610 by bolts. The gripper cylinder 610 adopts a parallel opening and closing type, and the clamping force can be adjusted in the range of 5-20N by the pressure regulating valve. A stable limiting protrusion 611 is provided at the junction of the cylinder fixing block 69 and the bottom surface of the gripper cylinder 610. The gripping part of the gripper cylinder 610 is provided with a pair of gripper blocks that are fitted and fixed to the outer contour of the lock to be tested. The gripper blocks are customized according to the shape of the lock and are made of food-grade silicone wrapped with high-strength nylon to avoid pinching and ensure gripping firmness. The gripper thickness of the gripper blocks matches the height difference between the middle and the sides of the fixed fixture.

[0044] The bottom of the cylinder fixing block 69 is also fixed with a pressure plate 612 that passes through the gripper cylinder, and pressure handles 613 are provided at both ends of the pressure plate. The pressure plate 612 is made of stainless steel, and the pressure handles 613 assist in positioning while the gripper is gripping, preventing the lock from shifting during the transfer process.

[0045] The working process of this utility model is as follows: when the fixed fixture carrying the lock moves to the unloading station 14, the unloading component 4 on the unloading rack 2 starts working: the servo rotating part 5 drives the picking part 6 to accurately grab the tested lock, and transfers it to the OK conveyor line 71 or NG conveyor line 72 of the transmission part 7 according to the test results. Among them, the NG part finally enters the storage compartment 721 with the touch combination lock 722. After that, the servo rotating part 5 drives the picking part to reset to the unloading station, forming a fully automatic closed-loop process.

[0046] This utility model does not improve any software programs or methods; it only improves the structure. The methods or software programs involved in the debugging and control of the PLC control device and related sensors are all based on existing methods or software program design books, manuals or product manuals by those skilled in the art, combined with the functions involved in the principles and effects of this utility model, and can be implemented by writing their own programs.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
