[0033] Referring to Figure 1 , Figure 2 and Figure 5The buffer mechanism 2 comprises an inclined plane plate 201 fixed on the left side of the detection table 1, which provides a basic supporting slope for the buffering process. The top of the inclined plane plate 201 is connected with two slide rails 203, the outer wall of the two slide rails 203 and the force receiving claw 204 form a sliding connection relationship, the bottom of the force receiving claw 204 is provided with two sliding grooves 206, and the inner wall of the two force receiving claws 204 and the outer wall of the two slide rails 203 are matched with each other, so that the force receiving claw 204 can slide on the slide rail 203, avoiding the phenomenon of shaking and deviation. The left side of the inclined plane plate 201 is fixedly connected with a limiting plate 202, and the left side of the limiting plate 202 is fixedly connected with a spring arm 205. The right side of the spring arm 205 is fixedly connected with the left side of the force receiving claw 204. The spring arm 205 can be limited by the limiting plate 202, and is located between the force receiving claw 204 and the limiting plate 202. When the injection molded part 24 after detection slides down along the inclined plane plate 201 and contacts the force receiving claw 204, the force receiving claw 204 will slide along the slide rail 203 under the impact force of the injection molded part 24. At this time, the spring arm 205 will be elastically deformed, so as to effectively absorb the impact force of the injection molded part 24 and convert it into the elastic potential energy of the spring arm 205, thereby realizing the buffering protection of the injection molded part 24, ensuring that the injection molded part 24 can stop smoothly on the inclined plane plate 201, avoiding damage caused by collision and affecting the subsequent processing process.

[0034] With reference to Figure 1 , Figure 3 and Figure 4 , the plurality of rollers 10 are in contact with the middle outer wall of the injection molded part 24 in a fitted state, which can ensure that the injection molded part 24 can still roll on the detection table 1 when the injection molded part 24 is moved. The outer wall of the two gear wheels 12 is in meshing connection with the bottom of the two gear racks 13. When the brake motor 11 starts, the gear wheel 12 will rotate under the gear rack 13, converting the rotary power of the brake motor 11 into the linear movement power of the connecting plate 4, controlling the left and right position movement of the detection arm 7 on the detection table 1. The outer wall of the middle of the two detection arms 7 is fixedly connected with a force receiving block 15, and the bottom outer wall of the force receiving block 15 is fixedly connected with a force receiving block 16. The two force receiving blocks play a supporting role in the structure of the detection arm 7. A plurality of rollers 17 are rotatably connected on the adjacent side of the two force receiving blocks 16 and the two force receiving blocks 15. The outer wall of the roller 17 is in contact with the outer wall of the detection table 1. When the detection arm 7 moves, the roller 17 can roll on the outer wall of the detection table 1, greatly reducing the friction, making the movement of the detection arm 7 more smooth.

[0035] With reference to Figure 1 , Figure 2 and Figure 3The top left side of the detection table 1 is fixedly connected with an indicator light 19. When there is a quality problem during the detection process, the indicator light 19 can intuitively convey relevant information to the operator by lighting up the light. On the right side of the indicator light 19, a loudspeaker 18 is connected. The loudspeaker 18 cooperates with the indicator light 19 to further enhance the effect of information transmission. Two lighting strips 20 are fixedly connected to the top outer wall of the detection table 1. The two lighting strips 20 provide sufficient lighting environment for the detection area, so that the operator can clearly see the details of the injection molding part 24 when observing the injection molding part 24. The top right side of the detection table 1 is fixedly connected with a control panel 21. The control panel 21 can set and adjust the parameters of the detection device. The bottom four corners of the detection table 1 are connected with support legs 22. The support legs 22 provide support for the detection table 1. The bottoms of the plurality of support legs 22 are fixedly connected with anti-skid pads 23. The anti-skid pads 23 can increase the friction between the support legs 22 and the ground, and improve the stability of the detection table 1.

[0036] Working principle: The injection molding part 24 is placed on the two guide rails 14 on the top of the detection table 1, and its two ends can roll on the guide rails 14, which is convenient for adjusting the detection angle. During detection, the brake motor 11 is started, and its output end drives the gear 12 to rotate. Since the gear 12 is engaged with the rack 13 at the bottom of the detection table 1, the rotation of the gear 12 will be converted into linear motion, thereby driving the connecting plate 4 and the detection arm 7 and the telescopic module 6 connected thereto to move left and right on the detection table 1. The detection arm 7 can slide in the moving groove 1 3, and the telescopic module 6 can slide left and right in the moving groove 2 5 and can be telescoped up and down. When the telescopic module 6 is telescoped to the appropriate position, the control clamp 9 clamps the injection molding part 24, and the roller 1 0 in the inner wall of the control clamp 9 contacts the injection molding part 24, so that the injection molding part 24 can still roll to the left on the detection table 1 in the clamped state. At this time, the plurality of light sensors 8 in the inner wall of the detection arm 7 detect the surface condition of the injection molding part 24. When the injection molding part 24 rolls around, the light sensors 8 transmit the data sensed to realize comprehensive detection of the injection molding part 24, complete the entire detection process and obtain accurate detection results.

[0037] And, when the injection molding piece 24 completes detection, it slides downward along the inclined plane plate 201 under the action of gravity, because the inclined plane plate 201 has a certain inclination angle, the injection molding piece 24 will obtain a certain speed and kinetic energy, when it contacts the force claw 204, the force claw 204 is impacted by the injection molding piece 24, so that the force claw 204 slides along the slide rail 203 in a specified direction, in the sliding process of the force claw 204, the spring arm 205 connected to the left side of the force claw 204 is compressed because of the movement of the force claw 204, the restoring force of the spring arm 205 is opposite to the impact force direction of the injection molding piece 24 to the force claw 204, so as to gradually offset the kinetic energy of the injection molding piece 24, under the limiting of the limiting plate 202 to the spring arm 205, it is ensured that the buffering process is carried out in a controllable range, when the spring arm 205 finally completely absorbs the kinetic energy of the injection molding piece 24, the injection molding piece 24 will stay on the inclined plane plate 201 under the support of the force claw 204, waiting for subsequent collection, protecting the injection molding piece 24 from appearance defect problems caused by collision, guaranteeing the smooth progress of product quality and subsequent processing flow.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the utility model have described, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principles of the utility model, should be contained in the protection scope of the utility model.
