[0022] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0023] Embodiment 1, in combination with the attached Figure 1-3 A detection device for go pieces includes a conveyor belt device body 1 with a belt body 11, flanges 12 are provided on both sides of the outer belt surface of the belt body 11 to prevent go pieces from overflowing, a feeding hopper 2 matching the belt body 11 is provided at one end of the conveyor belt device body 1, a guide plate 3 is provided at the other end of the conveyor belt device body 1, which is inclined up and down and the upper end is correspondingly fitted with the outer belt surface of the belt body 11, a brush plate 4 capable of moving go pieces is provided above the conveyor belt device body 1, and a detection device body 5 is provided above the conveyor belt device body 1 at positions corresponding to the brush plate 4 and the guide plate 3.

[0024] As needed, the detection device body 5 includes an image processing module 52 for collecting images of go pieces on the outer surface of the belt body 11, for obtaining the images of go pieces collected by the image acquisition module 51, and for processing and analyzing the images, and an alarm module 53 for issuing alarm information; the image processing module 52 signal is connected to the image acquisition module 51, and the alarm module 53 signal is connected to the image processing module 52; that is, when the image processing module 52 processes and analyzes the go piece image, it is found that the corresponding go piece surface has defects, such as cracks, etc., the control system of the detection device controls the alarm module 53 to issue an alarm message to remind the staff to sort out the go pieces.

[0025] Furthermore, the detection device body 5 may also have a light source for auxiliary lighting.

[0026] It should be noted that: since the image processing module 52 adopts the equipment in the prior art, its working principle will not be described in detail here.

[0027] It should be noted that: before use, a collection box needs to be placed below the lower end of the guide plate 3 to place the Go pieces scattered on the ground after detection.

[0028] When in use, first pour the go pieces to be detected into the feeding hopper 2, and then move the go pieces to be detected through the discharge port of the feeding hopper 2 to the outer surface of the belt body 11. At this time, there are two postures of the go pieces. The first is that the base plate at the bottom of the go piece contacts the outer surface of the belt body 11; the second is that the oblate top of the go piece contacts the outer surface of the belt body 11. The go pieces in this posture cannot be detected by the detection device body 5. After the go pieces pass through the brush plate 4, since the base plate of the go pieces in the first posture contacts the outer surface of the belt body 11, the posture is relatively stable, so it will not turn over. Since the oblate top of the go piece in the second posture contacts the outer surface of the belt body 11, the go piece in this posture is unstable, so it will turn over after being blocked by the brush plate 4 and become the go piece in the first posture; then it is detected by the detection device body 5. When the detection device body 5 detects that there is a defect on the surface of a go piece, the alarm module 53 sounds an alarm to remind the staff. At this time, the staff can sort out the go piece. The go piece without defects on the surface moves to the rear end of the conveyor belt equipment body 1, is shoveled off by the guide plate 3, and falls into the collection box.

[0029] As needed, multiple image acquisition modules 51 and alarm modules 53 can be arranged at intervals along the width direction of the conveyor belt equipment body 1, and the two are arranged one by one, so that the conveyor belt equipment body 1 can be divided into multiple areas along the width. For example, since the image acquisition module 51 has two left and right modules, when the image of a go piece captured by the image acquisition module 51 on the left is analyzed, the alarm module 53 on the left sends an alarm signal. At this time, the area where the staff determines the go piece on the conveyor belt equipment body 1 can be narrowed down, and the position of the go piece can be determined more conveniently.

[0030] As needed, the conveyor belt equipment body 1 includes a mounting frame 13, an active roller 14 is provided at one end of the top of the mounting frame 13 corresponding to the guide plate 3, and a passive roller 15 is provided at the other end of the top of the mounting frame 13. The active roller 14 and the passive roller 15 are transmission-coordinated with the belt body 11.

[0031] Furthermore, in order to prevent the top of the belt body 11 from sagging and affecting the normal operation of the brush plate 4 and the detection device body 5, a support slide 16 for supporting the inner belt surface of the upper belt body 11 is provided at the top of the mounting frame 13 between the active roller 14 and the passive roller 15; in this way, the support slide 16 supports the inner top surface of the belt body 11 to ensure that the upper section of the belt body 11 is in a horizontal posture.

[0032] Furthermore, a slide groove 131 is provided at one end of the top of the mounting frame 13 which is away from the guide plate 3, and the end of the passive roller 15 is movably connected to the slide groove 131 through a slider 17; the mounting frame 13 is also provided with a tensioning spring 18 which can make the slider 17 have a tendency to move away from the active roller 14; in this way, the slider 17 can be pushed outward by the tensioning spring 18, so that the passive roller 15 has a tendency to move away from the active roller 14, thereby making the belt body 11 in a tensioned posture.

[0033] As required, the hopper 2 includes an outer plate 21, and both sides of the outer plate 21 are provided with side panels 22 extending inwardly, and the two side panels 22 are slidably matched with inner panels 23 on the sides away from the outer plate 21, so that the size of the discharge port of the hopper 2 can be changed by sliding the inner panels 23;

[0034] Furthermore, the inner surfaces of the two side panels 22 are provided with slots that are inclined up and down or up and down, and the inner panel 23 is inserted into the slots. By moving the inner panel 23 up and down or up and down, the function of changing the size of the discharge port of the hopper 2 is realized, thereby controlling the speed of the go pieces being discharged, and preventing the go pieces from piling up near the discharge port in the inner cavity of the hopper 2. Specifically, a bracket for fixing the hopper 2 is provided at the end of the conveyor belt device body 1 corresponding to the hopper 2.

[0035] Embodiment 2, combined with the attached Figure 1-2 A detection device for go pieces, based on the first embodiment, a fixed bracket 6 is provided at a position below the guide plate 3 on the conveyor belt equipment body 1, the outer end of the fixed bracket 6 is hinged to the guide plate 3, and a tension spring 7 is provided between the fixed bracket 6 and the lower plate surface of the guide plate 3, so that the upper end of the guide plate 3 is in close contact with the outer belt surface of the belt body 11.

[0036] In this way, the guide plate 3 can be pulled by the tension spring 7 so that the upper end of the guide plate 3 is in close contact with the outer surface of the belt body 11, thereby preventing a gap from appearing between the upper end of the guide plate 3 and the outer surface of the belt body 11, resulting in the inability to shovel off the go pieces, causing the go pieces to accumulate at the rear end of the belt body 11.

[0037] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
