[0002] Appearance inspection refers to the use of automated equipment and technology to inspect the appearance of products to ensure that they meet design requirements and customer standards. This inspection method plays a vital role in quality control and can help companies improve production efficiency and product quality and reduce defective product rates. Appearance inspection includes color, texture, shape, size and other aspects to ensure that products meet design requirements and customer standards.

[0003] However, the existing appearance inspection setup requires the product to be positioned at a specified position during inspection (inspecting the size of the product), so that two pairs of clamping structures are controlled to move by two driving sources to achieve synchronous horizontal and lateral clamping. The operation is relatively complicated and the production cost is high.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0023] Embodiment 1: like Figures 1 to 10 As shown, an online sorting machine for detecting appearance defects of products includes a conveying detection unit 100, a fixed guide unit 200 and a reversing push unit 300. The conveying detection unit 100 includes a feeding roller conveyor belt 101. Two dividing roller conveyor belts 102 in opposite directions are installed at the end of the feeding roller conveyor belt 101. The dividing roller conveyor belt 102 is arc-shaped. The feeding roller conveyor belt 101 and the dividing roller conveyor belt 102 can transport products. The feeding roller conveyor belt 101 and the dividing roller conveyor belt 102 are prior arts, and the working principle is not repeated here. An appearance detection probe 1053 is installed on the top of the feeding roller conveyor belt 101.

[0024] The fixed guide unit 200 includes a positioning plate 201, which is installed at the connection between the feeding roller conveyor belt 101 and the dividing roller conveyor belt 102. A pair of insertion rods 2011 are slidably installed on the positioning plate 201, and a locking block 202 is installed on the insertion rod 2011. A sliding rod 203 is movably inserted inside the locking block 202, and a pressing plate 2031 is installed at one end of the sliding rod 203, and an extrusion block 2034 is installed at the other end of the sliding rod 203. An adjusting motor 204 is installed on the side wall of the feeding roller conveyor belt 101, and a pressing plate 2042 is installed on the output end of the adjusting motor 204. The adjusting motor 204 drives the pressing plate 2042 to rotate, and the pressing plate 2042 covers the locking block 202. A top plate 205 is installed on the side wall of the pressing plate 2042, and a slope 2051 is installed on the top plate 205. The slope 2051 rotates synchronously with the pressing plate 2042, and the slope 2051 and the extrusion block 2034 squeeze each other; when the product moves along the feeding roller conveyor belt to the surface of the positioning plate, the operator starts the adjusting motor, and the adjusting motor drives the pressing plate to rotate toward the center. When the pressing plate rotates, the pressing plate can press the product between the positioning plate and the insertion rod, thereby achieving the purpose of positioning. When the pressing plate rotates, the top plate on the surface of the pressing plate can contact the extrusion block. As the top plate rotates, the slope will squeeze the extrusion block, and the extrusion block pushes the insertion rod to slide. The insertion rod moves the pressure plate at the end toward the center, thereby squeezing the product on the surface of the pressure plate. Finally, the product is positioned horizontally and vertically through a driving source, which makes the operation simpler and convenient for appearance detection probes.

[0025] The reversing push unit 300 includes a fixed block 301, which is installed at the connection between the feeding roller conveyor belt 101 and the dividing roller conveyor belt 102. A reversing motor 302 is installed on the fixed block 301, and the output end of the reversing motor 302 and the back of the positioning plate 201 are connected to each other. A pair of rocker arms 303 are rotatably installed on the side wall of the fixed block 301, and a guide slider 3032 is rotatably installed on each pair of rocker arms 303, and the guide slider 3032 is movably connected to the insertion rod 2011, and a synchronization rod 305 is installed on the insertion rod 2011. A fixed plate 306 is installed on the side wall of the positioning plate 201, and a combination groove is opened on the fixed plate 306, and the combination groove includes an inclined groove 3061 and a flat groove 3062, and the synchronization rod 305 and the combination groove are slidably connected. After the inspection is completed, the operator can start the reversing motor to control the deflection of the positioning plate with the product. When the positioning plate deflects, the insertion rod on one side can move toward the center under the positioning of the rocker arm, thereby pushing the product to move, and the insertion rod on the other side slides along the inclined groove under the positioning of the rocker arm, so that the insertion rod retracts into the inner side of the positioning plate, making it convenient for the horizontally moving insertion rod to push the entire product to move, so that the product moves to the designated material separation roller conveyor belt, thereby achieving the purpose of sorting.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, in a specific embodiment, a plurality of pairs of support legs 103 are installed at the bottom of the feeding roller conveyor belt 101 and the dividing roller conveyor belt 102, and the support legs 103 serve the purpose of support. A cross beam 1031 is installed between the adjacent support legs 103 in the transverse direction, and the heights of the adjacent cross beams 1031 are different. A reinforcing rib 1032 is installed between the adjacent support legs 103 in the longitudinal direction, and the reinforcing rib 1032 is cross-shaped. The cross beam 1031 and the reinforcing rib 1032 improve the structural strength of the equipment.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, further, a pair of guide blocks 104 are installed on the feeding roller conveyor belt 101, and a gap is left between the pair of guide blocks 104. The side wall of the guide block 104 away from the positioning plate 201 is provided with an inclined surface 1041, and the other side of the guide block 104 is provided with an arc surface 1042, and the arc surface 1042 is slidably connected to the end of the pressing plate 2042. An adjustment plate 1043 is installed between the pair of guide blocks 104 through bolts. The feeding roller conveyor belt 101 can drive the product to slide on its surface. During the sliding process, the product can be guided by the guide block 104 to ensure that the product is always located at the center of the feeding roller conveyor belt 101, and the adjustment plate 1043 can control the position of the guide block 104, thereby controlling the purpose of the gap.

[0028] Embodiment 2: The difference between the above embodiment and this embodiment is that: Figure 2 and Figure 3 As shown, a transverse plate 1051 is installed on the outer shell of the appearance detection probe 1053, and the transverse plate 1051 is horizontally installed on the top of the feeding roller conveyor belt 101. Support arms 105 are installed at both ends of the transverse plate 1051. The bottom of the support arm 105 is welded to the outer wall of the feeding roller conveyor belt 101, and an inclined plate 1052 is installed on the inner wall of the support arm 105. The end of the inclined plate 1052 is interconnected with the bottom of the transverse plate 1051.

[0029] like Figure 4 , Figure 5 and Figure 6As shown, in a specific embodiment, a sliding cavity 2021 is provided inside the locking block 202, a baffle 2033 is slidably provided inside the sliding cavity 2021, one end of the baffle 2033 is connected to the sliding rod 203, the other end of the baffle 2033 is connected to the extrusion block 2034, and the surface of the extrusion block 2034 is chamfered, an anti-slip groove 2032 is provided at the end of the pressing plate 2031, an extrusion spring 2035 is sleeved on the sliding rod 203, one end of the extrusion spring 2035 is clamped on the inner wall of the sliding cavity 2021, and the other end of the extrusion spring 2035 is clamped on the baffle 2033. A rotating shaft 2041 is installed at the output end of the regulating motor 204, and the rotating shaft 2041 and the pressing plate 2042 are connected to each other, a bearing seat is installed at the end of the rotating shaft 2041, and the side wall of the pressing plate 2042 and the slope 2051 are connected to each other. The adjusting motor 204 can rotate the rotating shaft 2041, and the rotating shaft 2041 can drive the pressing plate 2042 to move toward the center. When the pressing plate 2042 rotates to the center position, the pressing plate 2042 can squeeze the product on the positioning plate 201, thereby achieving the purpose of preliminary fixation. When the pressing plate 2042 rotates, the top plate 205 on the side wall of the pressing plate 2042 can be released from the extrusion block 2034. With the continuous rotation, the slope 2051 on the side wall of the top plate 205 can squeeze the extrusion block 2034. At this time, the extrusion block 2034 drives the baffle 2033 to slide inside the sliding cavity 2021. The sliding of the baffle 2033 can compress the extrusion spring 2035. The extrusion spring 2035 is used to facilitate the subsequent resetting operation. When the baffle 2033 slides, the insertion rod 2011 on the baffle 2033 slides synchronously inside the sliding cavity 2021 to move the pressing plate 2031 toward the center. The movement of the pressing plate 2031 toward the center can squeeze and fix the product, and the stability is improved by the anti-slip groove 2032.

[0030] like Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, further, a mounting plate 3011 is welded to the side wall of the fixed block 301, and the mounting plate 3011 is fitted with the outer frame of the material-dividing roller conveyor belt 102, and a locking bolt is screwed between the outer frame of the material-dividing roller conveyor belt 102 and the mounting plate 3011, and a positioning rod 3013 is installed on the outer frame of the material-dividing roller conveyor belt 102, and a plug hole 3012 is opened at the bottom of the fixed block 301, and the plug hole 3012 and the positioning rod 3013 are movably plugged. The plug hole 3012 and the positioning rod 3013 serve the purpose of positioning.

[0031] Embodiment 3: The difference between the above embodiment and this embodiment is that: Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, a mounting bracket 3021 is installed on the side wall of the commutation motor 302, and the mounting bracket 3021 is connected to the side wall of the fixed block 301, and a synchronous shaft 3022 is installed on the output end of the commutation motor 302, and a fixing seat 3014 is rotatably installed on the synchronous shaft 3022, and the fixing seat 3014 is welded to the side wall of the fixed block 301, and a positioning seat 3023 is fixedly installed on the synchronous shaft 3022, and the positioning seat 3023 and the positioning plate 201 are connected to each other. The commutation motor 302 drives the synchronous shaft 3022 to rotate, and the positioning seat 3023 on the synchronous shaft 3022 can drive the entire positioning plate 201 to rotate.

[0032] like Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in a specific embodiment, a guide groove 3033 is horizontally opened on the positioning plate 201, the guide groove 3033 and the guide slider 3032 are slidably connected, and the insertion rod 2011 is inserted in the guide groove 3033, and a synchronization plate 3031 is installed on the side wall of the guide slider 3032, the synchronization plate 3031 and the rocker arm 303 are rotatably connected, and the synchronization plate 3031 is slidably fitted on the back of the positioning plate 201, and a guide protrusion 3051 is set at the bottom of the synchronization rod 305, and the guide protrusion 3051 is slidably set on the flat groove 3062. When the positioning plate 201 rotates counterclockwise, the height of the left side of the positioning plate 201 becomes lower as a whole, and then a guide slider 3032 is slidably provided on the guide slot 3033 of the positioning plate 201. At this time, the synchronous plate 3031 on the guide slider 3032 is limited by the rocker arm 303 as a whole, and then the guide slider 3032 on the left side moves to the left along the guide slot 3033, and the insertion rod 2011 inside the guide slider 3032 has a tendency to move to the left as a whole, and then the synchronization rod 305 and the guide protrusion 3051 on the side wall of the insertion rod 2011 slide synchronously. At this time, the guide protrusion 3051 on the synchronization rod 305 slides on the inclined slot 3061 in the combination slot, and then the synchronization rod 305 as a whole moves in the direction of the inclined slot 3061. At this time, the synchronization rod 305 and the insertion rod 2011 on the surface can be pulled to be compressed into the positioning plate 201.

[0033] like Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, further, a positioning groove 3042 is provided on the back of the positioning plate 201, and a positioning slider 304 is slidably arranged on the positioning groove 3042, and a guide rod 3043 is movably arranged inside the positioning slider 304, and both ends of the guide rod 3043 are installed on the side walls of the positioning groove 3042, and a return spring 3044 is sleeved on the guide rod 3043, one end of the return spring 3044 is clamped on the side wall of the positioning groove 3042, and the other end of the return spring 3044 is clamped on the side wall of the positioning slider 304, and a connecting plate 3041 is installed on the side wall of the positioning slider 304, and the connecting plate 3041 and the synchronous plate 3031 are connected to each other. When the guide slider 3032 slides, the synchronous plate 3031 on the side wall of the guide slider 3032 drives the connecting plate 3041, and the connecting plate 3041 drives the positioning slider 304 to slide in the positioning slide groove 3042, and the positioning slider 304 also slides on the guide rod 3043 at this time, playing a guiding role, and the reset spring 3044 can be compressed during the sliding process, and the reset operation is convenient for the later stage through the reset spring 3044 The implementation principle of an online sorting machine for detecting product appearance defects in this embodiment is as follows: The operator first places the product on the feeding roller conveyor belt 101 , which can drive the product to slide on its surface. During the sliding process, the product can be guided by the guide block 104 to ensure that the product is always located at the center of the feeding roller conveyor belt 101 .

[0034] When the product slides to the end of the feeding roller conveyor belt 101, the adjusting motor 204 can be started, the adjusting motor 204 can rotate the rotating shaft 2041, and the rotating shaft 2041 can drive the pressing plate 2042 to move toward the center. When the pressing plate 2042 rotates to the center position, the pressing plate 2042 can squeeze the product on the positioning plate 201, thereby achieving the purpose of preliminary fixation.

[0035] When the pressing plate 2042 rotates, the top plate 205 on the side wall of the pressing plate 2042 can be released from the extrusion block 2034. With the continuous rotation, the slope 2051 on the side wall of the top plate 205 can squeeze the extrusion block 2034. At this time, the extrusion block 2034 drives the baffle 2033 to slide inside the sliding cavity 2021. The sliding of the baffle 2033 can compress the extrusion spring 2035. The extrusion spring 2035 is used to facilitate the subsequent resetting operation. When the baffle 2033 slides, the insertion rod 2011 on the baffle 2033 slides synchronously inside the sliding cavity 2021 to move the pressing plate 2031 toward the center. The movement of the pressing plate 2031 toward the center can squeeze and fix the product, and the stability is improved by the anti-slip groove 2032.

[0036] Through the above operations, the longitudinal and lateral positioning of the product can be achieved, ensuring that the detection is more accurate.

[0037] Then the operator starts the appearance inspection probe 1053, determines whether the product meets the requirements through the appearance inspection probe 1053, and sends the inspection result to the computer. The computer controls the reversing motor 302 to start, thereby allowing the product to flow to different conveyor belts. The appearance inspection probe 1053 is a prior art, and its working principle will not be repeated here.

[0038] When the detection is completed, the operator starts the adjustment motor 204 in reverse, thereby unlocking the lateral positioning and the longitudinal positioning, so as to facilitate the product to flow to the material distribution roller conveyor belt 102.

[0039] The commutation motor 302 rotates forward or reverse according to the received signal.

[0040] When the reversing motor 302 rotates counterclockwise ( Fig. 9 As a reference), at this time, the reversing motor 302 drives the synchronous shaft 3022 to rotate counterclockwise, and the positioning seat 3023 on the synchronous shaft 3022 can drive the entire positioning plate 201 to rotate counterclockwise.

[0041] When the positioning plate 201 rotates counterclockwise, the product on the positioning plate 201 rotates synchronously, and the product rotates in an inclined state.

[0042] When the positioning plate 201 rotates counterclockwise, the height of the left side of the positioning plate 201 becomes lower as a whole, and then a guide slider 3032 is slidably provided on the guide slot 3033 of the positioning plate 201. At this time, the synchronous plate 3031 on the guide slider 3032 is limited by the rocker arm 303 as a whole, and then the guide slider 3032 on the left side moves to the left along the guide slot 3033, and the insertion rod 2011 inside the guide slider 3032 has a tendency to move to the left as a whole, and then the synchronization rod 305 and the guide protrusion 3051 on the side wall of the insertion rod 2011 slide synchronously. At this time, the guide protrusion 3051 on the synchronization rod 305 slides on the inclined slot 3061 in the combination slot, and then the synchronization rod 305 has the direction of moving toward the inclined slot 3061 as a whole, and at this time, the synchronization rod 305 and the insertion rod 2011 on the surface can be pulled to be compressed into the positioning plate 201, and finally the insertion rod 2011 can be made not to contact the surface product.

[0043] When the positioning plate 201 rotates counterclockwise, the height of the right side of the positioning plate 201 becomes higher as a whole. Through the limit of the rocker arm, the guide slider 3032 can be driven to slide to the left along the guide slot 3033, and the right side insertion rod 2011 slides to the right along the flat slot 3062. Therefore, the right side insertion rod 2011 can push the product to move, so that the product can be separated from the positioning plate 201 smoothly, and the material separation roller conveyor belt 102 can drive the product to move as a whole, thereby achieving the purpose of sorting.

[0044] When the guide slider 3032 slides, the synchronous plate 3031 on the side wall of the guide slider 3032 drives the connecting plate 3041, and the connecting plate 3041 drives the positioning slider 304 to slide in the positioning slide groove 3042. At this time, the positioning slider 304 also slides on the guide rod 3043, which plays a guiding role. In addition, the reset spring 3044 can be compressed during the sliding process, and the reset operation is facilitated by the reset spring 3044 at a later time.
