DETAILED DESCRIPTION

[0040] A preferred embodiment is given below and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0041] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0042] Example 1

[0043] like Figure 1 As shown, embodiment 1 of the present invention provides a testing method, comprising the following steps:

[0044] S1: transport material 1 to the test position on conveyor belt 2;

[0045] S2: lift the material 1 on the test position;

[0046] S3: The grabbing element 42 extends into the testing position and grabs the material 1;

[0047] S4: Test material 1.

[0048] Specifically, in the testing method of this embodiment 1, the test position refers to the position at which the material 1 is to be grasped while being conveyed on the conveyor belt 2. This position is used to allow the grasping element 42 space to grasp the material 1 when the material 1 is lifted. The testing method of this embodiment 1 achieves automated control of the material 1 testing, resulting in higher efficiency and better results.

[0049] like Figure 2As shown, as a preferred embodiment of the present invention, in the testing method of Example 1, before step S1, a further step S0 is included: transporting material 1 to a waiting position on conveyor belt 2 located before the testing position, and lifting material 1 from the waiting position. Specifically, the waiting position is provided and step S0 is added before step S1 so that when material 1 is grabbed from the testing position for testing, the conveyor belt 2 remains free of material 1, forming a system that tests material 1 one by one at fixed time intervals.

[0050] like Figure 3 As shown, as a preferred embodiment of the present invention, in the testing method of Example 1, step S3 further includes: S31: After the gripping element 42 is extended into the testing position, the material 1 on the testing position falls onto the gripping element 42. Specifically, after the material 1 on the testing position is lifted up, the gripping element 42 is extended under the material 1 in the testing position, and then the material 1 falls onto the gripping element 42 by gravity and connects with the gripping element 42. Finally, the gripping element 42 is withdrawn from the testing position.

[0051] like Figure 4 As shown, as a preferred embodiment of the present invention, in the testing method of Example 1, after step S4, the following steps are further included: S5: the gripping element 42 grips the tested material 1 and transports it to the testing position on the conveyor belt 2; S6: the material 1 at the testing position is lifted and the gripping element 42 is withdrawn; S7: the material 1 at the testing position drops onto the conveyor belt 2. Specifically, steps S5, S6, and S7 are the reverse steps of steps S1, S2, and S3. Adopting steps S5, S6, and S7 of this preferred embodiment can maintain the stability and accuracy of the entire material 1 testing system, keeping all materials 1 in a consistent rhythm throughout the entire testing process, thereby improving the efficiency and effectiveness of material 1 testing.

[0052] like Figure 5 As shown, as a preferred embodiment of the present invention, in the testing method of Example 1, step S7 further includes: S71: Material 1 in the waiting position is dropped onto conveyor belt 2. Specifically, before material 1 is transported to the testing position, a waiting position is set on conveyor belt 2. Material 1 in this waiting position is simultaneously lifted up along with material 1 in the testing position. Material 1 in the waiting position waits for the material 1 in the testing position to be tested before simultaneously dropping onto conveyor belt 2. In this preferred embodiment, the waiting position ensures that no material 1 is on conveyor belt 2 during testing, thereby forming a material 1 testing system that tests each material 1 one by one.

[0053] Example 2

[0054] like Figures 6 to 9As shown, embodiment 2 of the present invention provides a material retrieving device, which includes: a lifting mechanism 3 and a gripping mechanism 4, wherein the lifting mechanism 3 is disposed on the conveyor belt 2 and is used to lift the material 1 on the conveyor belt 2; the gripping mechanism 4 is disposed on the side of the conveyor belt 2 and is used to grip the material 1. Specifically, the lifting mechanism 3 lifts the material 1, and the gripping mechanism 4 grips the material 1 for testing. This realizes automated control of the material 1 testing process and improves the efficiency and testing effect of the material 1.

[0055] As a preferred embodiment of the present invention, in the reclaiming device of Example 2, the lifting mechanism 3 includes a lifting cylinder 31, a lifting base plate 32, and two lifting frames 33; the lifting base plate 32 is connected to the conveyor belt 2; the lifting cylinder 31 is connected to the lifting base plate 32; the two lifting frames 33 are connected to the lifting base plate 32 and are respectively located on both sides of the conveyor belt 2; and the lifting cylinder 31 and the lifting base plate 32 are disposed below the conveyor belt 2. According to this preferred embodiment, when the material 1 is transported to the testing position, the lifting cylinder 31 at the testing position lifts the lifting base plate 32 and the two lifting frames 33, and the two lifting frames 33 lift the material 1 from both sides of the conveyor belt 2.

[0056] As a preferred embodiment of the present invention, in the reclaiming device of Example 2, along the conveying direction of the conveyor belt 2, each lifting frame 33 is provided with a support portion 331 at each end, and the four support portions 331 jointly support the material 1. Through this preferred embodiment, the four corners of the material 1 are supported and positioned.

[0057] As a preferred embodiment of the present invention, in the reclaiming device of Example 2, each support portion 331 is magnetically attracted to the material 1. In this preferred embodiment, the material 1 is magnetically attracted to the two lifting frames 33, thereby preventing the lifting frames 33 from being displaced due to collisions during the lifting of the material 1.

[0058] As a preferred embodiment of the present invention, in the material-retrieving device of Example 2, the jacking mechanism 3 further includes a connecting plate 34 and two jacking guide pillars 35. The jacking cylinder 31 and the two jacking guide pillars 35 are respectively connected to the upper surface of the connecting plate 34. The two jacking guide pillars 35 are respectively located on both sides of the jacking cylinder 31. The two jacking guide pillars 35 are arranged in a one-to-one correspondence with the two jacking frames 33, and each jacking frame 33 slides up and down along the corresponding jacking guide pillars 35. Through this preferred embodiment, the two jacking guide pillars 35 and the jacking cylinder 31 are all connected to a connecting plate 34, and the jacking frame 33 is controlled to rise and fall along the two jacking guide pillars 35 by the jacking cylinder 31, thereby avoiding the phenomenon that the jacking base plate 32 and the two jacking frames 33 rotate when there is only the jacking cylinder 31 but no two jacking guide pillars 35.

[0059] As a preferred embodiment of the present invention, in the retrieving device of Example 2, the grabbing mechanism 4 includes a body 41, a grabbing element 42, a grabbing cylinder 43, and a grabbing guide rod 44. The grabbing guide rod 44 is disposed on the body 41 and is perpendicular to the conveyor belt 2. The grabbing cylinder 43 is coaxially mounted on the grabbing guide rod 44. The grabbing element 42 is connected to the grabbing cylinder 43 and is configured to slide along the grabbing guide rod 44 and extend between the material 1 and the conveyor belt 2 to grab the material 1. This preferred embodiment ensures that the grabbing element 42 can extend into or out of the conveyor belt 2 in the horizontal direction, perpendicular to the conveyor belt 2, and can quickly and accurately grab the material 1.

[0060] As a preferred embodiment of the present invention, in the retrieving device of Example 2, the gripping mechanism 4 further includes a gripping guide rail 45 and a slider 46. The gripping guide rail 45 is disposed on the body 41 and connected to the gripping element 42. The gripping guide rail 45 is parallel to the gripping guide rod 44. The slider 46 is connected to the body 41, and the gripping guide rail 45 is slidably connected to the slider 46. This preferred embodiment ensures that when the gripping element 42 moves in the horizontal direction, it will not be displaced horizontally parallel to the conveyor belt 2 or vertically perpendicular to the conveyor belt 2.

[0061] As a preferred embodiment of the present invention, in the retrieving device of Example 2, the gripping element 42 includes a plurality of positioning protrusions 421. These protrusions 421 are disposed on the surface of the gripping element 42 facing the material 1 and are used to position the material 1. This preferred embodiment enhances the gripping strength of the gripping element 42 on the material 1, ensuring that the speed of the gripping movement of the gripping element 42 in the horizontal direction perpendicular to the conveyor belt 2 is not limited by concerns that the material 1 may fall during the gripping process, thereby improving efficiency to a certain extent.

[0062] As a preferred embodiment of the present invention, in the material reclaiming device of Example 2, the material reclaiming device further includes a stop mechanism 5, which is provided on the conveyor belt 2 and is used to stop the material 1. Through this preferred embodiment, before the material 1 is about to reach the test position, the stop mechanism 5 is ready to stop the material 1 from moving forward, thereby ensuring that the jacking mechanism 3 has a certain amount of time to complete the jacking process, and at the same time, there is no need to control the conveyor belt 2 to start and stop continuously to consume the service life of the conveyor belt 2. In this preferred embodiment, the stop mechanism 5 can not only be provided in front of the material 1 in the transport direction, but can also be relatively provided at the rear of the material 1 at the test position, so that the two stop mechanisms 5 form a clamping and positioning effect, positioning the material 1 at the test position, and preventing the material 1 from undergoing large displacement.

[0063] As a preferred embodiment of the present invention, in the material retrieving device of Example 2, the stop mechanism 5 includes a stop bracket 51, a stop cylinder 52, a stop element 53, and a sensing element 54. The stop bracket 51 is connected to the conveyor belt 2 and is located between the two belts of the conveyor belt 2. The stop cylinder 52 is connected to the stop bracket 51, and the stop element 53 is connected to the stop cylinder 52. The stop element 53 is used to extend and retract in a direction perpendicular to the conveyor belt 2. The sensing element 54 is connected to the stop bracket 51 and is used to sense the material 1. According to this preferred embodiment, when the material 1 is about to reach the test position, the sensing element 54 responds, causing the stop element 53 to extend to block the transportation path of the material 1, limiting the material 1 to the test position. After the material 1 completes the test and falls back onto the conveyor belt 2, the stop element 53 retracts to allow the material 1 to continue to be transported on the conveyor belt 2.

[0064] As a preferred embodiment of the present invention, in the reclaiming device of Example 2, a limiting notch 11 is provided on the material 1, and the stopping element 53 includes a stopping surface 531 for stopping the material 1. The structure of the stopping surface 531 is designed to cooperate with the structure of the limiting notch 11. Through this preferred embodiment, the interaction between the limiting notch 11 and the matching stop surface 531 prevents the material 1 from shifting in a direction perpendicular to the conveyor belt 2. Furthermore, the stopping mechanism 5 is provided at both ends of the material 1 along the direction in which the material 1 is transported, which can further enhance the clamping and positioning effect of the stopping mechanism 5 on the material 1.
