[0033] In actual use, the detection device 100 first carries the workpiece 200 by the carrier 213, the two ends of the workpiece 200 extend out of the carrier 213 along the first direction, and the lower surface of the workpiece 200 has a gap with the upper surface of the carrier 211, then the elastic member 23 elastically pushes the positioning member 22 to move towards the bearing body 212, so that the positioning member 22 pushes the workpiece 200 to the bearing body 212 to position the workpiece 200 to the carrier 213, then the first light source 32 emits the first light along the second direction towards the first detection member 31, the first light is irradiated to the first detection member 31 through the light transmission groove 11, the through groove 2111 and the workpiece 200, so that the first light forms a contour light along the second direction on the periphery of the workpiece 200, the first detection member 31 receives the contour light formed by the first light and obtains the image of the workpiece 200 to detect the workpiece 200 along the second direction, finally the rotating disc assembly 10 rotates the positioning assembly 20 to the front of the second light source 34, the second light source 34 emits the second light along the third direction towards the second detection member 33, because the lower surface of the workpiece 200 has a gap with the upper surface of the carrier 211, the second light forms a contour light along the third direction on the periphery of the workpiece 200, the second detection member 33 receives the contour light formed by the second light and obtains the image of the workpiece 200 to detect the workpiece 200 along the third direction, so that the first detection member 31 and the second detection member 33 respectively obtain the contour light formed on the periphery of the workpiece 200 along the second direction and the third direction, which improves the clarity of the image of the workpiece 200 obtained by the first detection member 31 and the second detection member 33, and further improves the detection accuracy.

[0034] Referring to Figure 2 and Figure 3 In some embodiments, the side of the carrier 211 away from the rotating disc assembly 10 is provided with two recess grooves 2112, and the two recess grooves 2112 are respectively arranged on the two sides of the carrier 213 along the first direction, and the second light irradiates to the second detection member 33 along the third direction through the recess groove 2112.

[0035] In this way, by arranging the two recess grooves 2112 on the two sides of the carrier 213 along the first direction, a large enough gap is formed between the lower surface of the workpiece 200 carried by the carrier 213 and the upper surface of the carrier 211, so that the second light irradiates to the second detection member 33 along the third direction through the recess groove 2112, avoiding that the carrier 211 blocks the contour light formed by the second light, which is beneficial to improve the detection accuracy of the second detection member 33.

[0036] Referring to Figure 3 In some embodiments, the side of the carrier 213 away from the carrier frame 21 is provided with a positioning groove 2131, the positioning groove 2131 is matched with the workpiece 200 and penetrates through the carrier 213 along the first direction, and the positioning groove 2131 is used to position the workpiece 200 along the third direction.

[0037] Therefore, by setting the positioning groove 2131 matched with the workpiece 200 to receive the workpiece 200, the positioning groove 2131 positions the workpiece 200 along the third direction, so that the workpiece 200 is stably kept in the placement position and the placement orientation on the carrier 213, avoiding the workpiece 200 from shaking during the detection process, and facilitating to ensure the detection stability of the workpiece 200.

[0038] Please continue to refer to Figure 3 In some embodiments, the groove wall of the positioning groove 2131 comprises a positioning plane 2132 and a guide inclined surface 2133, the positioning plane 2132 is vertically connected with the groove bottom of the positioning groove 2131, and the guide inclined surface 2133 is obliquely arranged relative to the positioning plane 2132 and connected with an end of the positioning plane 2132 away from the loading body 211, the guide inclined surface 2133 is used for guiding the workpiece 200 to move into the positioning groove 2131, so that the positioning plane 2132 positions the workpiece 200 along the third direction.

[0039] Therefore, by setting the above-mentioned positioning plane 2132 and guide inclined surface 2133, during the process of placing the workpiece 200 on the carrier 213, the guide inclined surface 2133 can guide the workpiece 200 to move into the positioning groove 2131, so that the positioning plane 2132 positions the workpiece 200 along the third direction, facilitating the workpiece 200 to be smoothly placed on the carrier 213.

[0040] Please refer to Figure 2 and Figure 3 In some embodiments, the positioning member 22 comprises a positioning part 221 and a poking part 222, the positioning part 221 is arranged on the through groove 2111 and extends out of the loading body 211 away from the turntable assembly 10, the positioning part 221 and the groove wall of the through groove 2111 respectively abut the two ends of the elastic member 23, the positioning part 221 is used for positioning the workpiece 200 along the first direction under the elastic action of the elastic member 23, and the poking part 222 is rotationally connected with the loading body 211 and connected with an end of the positioning part 221 adjacent to the turntable assembly 10, the poking part 222 is used for driving the positioning part 221 to move away from the abutting body 212 under the action of an external force.

[0041] Therefore, by setting the positioning part 221 to extend out of the loading body 211 away from the turntable assembly 10, it is ensured that the end of the positioning part 221 away from the turntable assembly 10 stably positions the workpiece 200 to the abutting body 212, and by setting the poking part 222, it is convenient for an operator or an external driving device to act on the positioning member 22, so as to stably drive the poking part 222 to drive the positioning part 221 to move away from the abutting body 212, facilitating the workpiece 200 to be detected to replace the workpiece 200 after detection and be placed on the carrier 213.

[0042] Please refer to Figure 3In some embodiments, the loading body 211 comprises a loading plate 2113, two limiting rods 2114, a rotating shaft 2115, and two support plates 2116. The two support plates 2116 are arranged to support the loading plate 2113 at intervals. A through slot 2111 is formed in the loading plate 2113. The carrier 213 is arranged on the upper surface of the loading plate 2113 at intervals with the abutting body 212 along the first direction. The two limiting rods 2114 are arranged on both sides of the through slot 2111 and connected with the lower surface of the loading plate 2113. The actuating portion 222 is rotatably connected between the two limiting rods 2114 through the rotating shaft 2115.

[0043] For further reference Figure 3 In some embodiments, an arc-shaped protrusion 2221 is arranged on the side of the actuating portion 222 facing the elastic member 23. The arc-shaped protrusion 2221 is arranged between the two limiting rods 2114 and sleeved on the rotating shaft 2115. The arc-shaped protrusion 2221 is used to avoid the limiting rods 2114 when the actuating portion 222 rotates.

[0044] In this way, by arranging the arc-shaped protrusion 2221, the actuating portion 222 can avoid the limiting rods 2114 when rotating between the two limiting rods 2114. Thus, the rotating angle range of the actuating portion 222 is improved, which is conducive to ensuring that the actuating portion 222 stably positions the workpiece 200 to the abutting body 212.

[0045] For further reference Figure 3 In some embodiments, the loading body 211 further comprises a mounting slot 2117. The mounting slot 2117 is formed in the slot wall of the through slot 2111 away from the abutting body 212. The mounting slot 2117 is used to accommodate and limit the elastic member 23.

[0046] In this way, by accommodating the elastic member 23 in the mounting slot 2117, the mounting slot 2117 limits the elastic force direction of the elastic member 23. Thus, it is ensured that the elastic member 23 stably provides elastic force along the first direction and drives the positioning portion 221 to rotate towards the abutting body 212.

[0047] For further reference Figure 1 In some embodiments, the rotating disc assembly 10 comprises a fixing member 12 and a rotating disc 13.

The rotating disc 13 is provided with a light-transmitting slot 11. The first detection member 31 and the second detection member 33 are arranged at intervals along the circumference of the rotating disc 13. The first detection member 31 and the first light source 32 are arranged on opposite sides of the rotating disc 13 along the third direction. The rotating disc 13 is used to drive the workpiece 200 to rotate, so that the first detection member 31 and the second detection member 33 detect the workpiece 200 in sequence. Exemplarily, the rotating disc 13 can be any rotating portion, rotating body or rotating plate capable of driving the workpiece 200 to rotate, such as a rotating sheet connected with a rotating motor.

[0048] Therefore, by setting the specific structure of the rotating disc assembly 10, the workpiece 200 positioned by the positioning assembly 20 is moved along the circumference of the rotating disc 13, so that the first detection member 31 and the second detection member 33 detect the workpiece 200 in turn, avoiding the mutual interference of the first light and the second light when the workpiece 200 is detected at the same position, thereby improving the detection accuracy, and facilitating the reasonable layout of the detection device 100.

[0049] Specifically, the number of the positioning assemblies 20 is multiple, and the multiple positioning assemblies 20 are arranged at intervals along the circumference of the rotating disc 13. The rotating disc 13 is provided with multiple light transmission grooves 11, and the multiple light transmission grooves 11 correspond to the multiple positioning assemblies 20 one by one. In this way, by setting multiple positioning assemblies 20, the workpiece can be simultaneously loaded and detected, which is beneficial to improve the detection efficiency.

[0050] Please continue to refer to Figure 1 In some embodiments, the detection device 100 further comprises a loading assembly 40, which is arranged adjacent to the rotating disc assembly 10.

For example, the loading assembly 40 can be any loading member, loading part or similar loading body capable of moving the workpiece 200, such as a mechanical hand.

[0051] In this way, by setting the loading assembly 40 described above, the workpiece 200 to be detected is loaded to the carrier 213, which realizes the rapid loading of the workpiece 200 to the positioning assembly 20, effectively reduces the overall operation time of the detection device 100, and improves the detection efficiency.

[0052] The working process of the detection device 100 described above is as follows:

[0053] Firstly, the loading assembly 40 places the workpiece 200 on the carrier 213. The carrier 213 receives the workpiece 200 through the positioning groove 2131 to position the workpiece 200 along the third direction. The two ends of the workpiece 200 extend out of the carrier 213 along the first direction, and the lower surface of the workpiece 200 has a certain gap with the upper surface of the carrier 211.

[0054] Then, the elastic member 23 elastically pushes the positioning member 22 towards the abutting body 212, so that the positioning member 22 pushes the workpiece 200 to the abutting body 212 to position the workpiece 200 to the carrier 213 along the first direction.

[0055] Then, the rotary disc 13 drives the workpiece 200 to move above the first light source 32, the first light source 32 emits the first light along the second direction towards the first detection member 31, the first light is irradiated to the first detection member 31 through the light-transmitting groove 11, the through groove 2111 and the workpiece 200, so that the first light forms the contour light along the second direction on the circumferential side of the workpiece 200, the first detection member 31 receives the contour light formed by the first light and obtains the image of the workpiece 200, so as to detect the workpiece 200 along the second direction;

[0056] Finally, the rotary disc 13 drives the workpiece 200 to continue to rotate, so that the second light source 34 and the second detection member 33 are located at opposite sides of the workpiece 200 along the third direction respectively, the second light source 34 emits the second light along the third direction towards the second detection member 33, and since the lower surface of the workpiece 200 and the upper surface of the loading body 211 have a certain gap, the second light forms the contour light along the third direction on the circumferential side of the workpiece 200, the second detection member 33 receives the contour light formed by the second light and obtains the image of the workpiece 200, so as to detect the workpiece 200 along the third direction, so that the first detection member 31 and the second detection member 33 obtain the contour light formed on the circumferential side of the workpiece 200 along the second direction and the third direction respectively, so as to improve the definition of the image of the workpiece 200 obtained by the first detection member 31 and the second detection member 33, and further improve the detection accuracy.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited.
