Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

These terms are mainly used to better describe the present utility model and its embodiments, rather than to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0055] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to the specific circumstances.

[0056] In addition, the terms "installed", "set up", "provided with", "connected", and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or constituent parts. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0057] In addition, terms such as "first", "second", "third", "fourth", etc. are mainly used to distinguish different devices, components, or constituent parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components, or constituent parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0058] During the production process of a workpiece, quality inspection of the workpiece is an important process and a crucial step for controlling the quality of the workpiece. The steps for quality inspection of the workpiece are as follows: First, the workpiece is manually loaded at the loading and unloading station; then, the manipulator drives the workpiece to the positioning station to position the workpiece; after positioning is completed, the manipulator drives the workpiece to the inspection station to inspect the workpiece; finally, after the inspection is completed, the manipulator brings the workpiece back to the loading and unloading station, and the workpiece is unloaded manually. In the process of quality inspection of the workpiece, positioning the workpiece is relatively important. From positioning the workpiece to inspecting the station, there is often a loss of accuracy, which in turn affects the inspection effect of the workpiece quality, and thus affects the yield of workpiece production.

[0059] In the related art, when inspecting the quality of a workpiece, it is necessary to complete the positioning of the workpiece through two positioning processes. It positions two adjacent sides of the workpiece respectively. First, it positions a pair of sides of the workpiece at one positioning station. After positioning is completed, the manipulator grabs the workpiece and moves it to the next positioning station to position the other pair of sides of the workpiece. In this way, there are more processes for positioning the workpiece, and the inspection after positioning the workpiece may affect the inspection effect due to loss of some positioning accuracy.

[0060] Based on this, the present application discloses a positioning mechanism that can achieve simultaneous positioning of the four sides of a workpiece at one positioning station, with relatively high positioning accuracy, avoiding loss of positioning accuracy during the transportation process between two positioning stations when the workpiece is positioned at two positioning stations, reducing the positioning processes, improving the efficiency of positioning the workpiece, and thus improving the efficiency of the entire inspection process of the workpiece.

[0061] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0062] Please refer toFigure 1 and Figure 2 , Figure 1 is a schematic structural diagram of the positioning mechanism 100 disclosed in the embodiment of the present application. Figure 2 is Figure 1 a top view of the positioning mechanism 100 in . The present application discloses a positioning mechanism 100, which is used to position a workpiece transported to the positioning station 301. The workpiece includes a first side, a second side opposite to the first side, a third side adjacent to the first side, and a fourth side opposite to the third side. Specifically, the positioning mechanism 100 includes a first positioning component 1, a second positioning component 2, and a base 6. The first positioning component 1 and the second positioning component 2 are both arranged on the base 6.

[0063] The first positioning component 1 includes a first positioning member 11 and a second positioning member 12. The first positioning member 11 and the second positioning member 12 are arranged on both sides of the positioning station 301 along the first horizontal direction X. The first positioning member 11 can reciprocate along the first horizontal direction X and is used to position the first side and the second side of the workpiece. The second positioning component 2 includes a third positioning member 21 and a fourth positioning member 22. The third positioning member 21 and the fourth positioning member 22 are arranged on both sides of the positioning station 301 along the second horizontal direction Y. The third positioning member 21 can reciprocate along the second horizontal direction Y and is used to position the third side and the fourth side of the workpiece. The second horizontal direction Y is perpendicular to the first horizontal direction X.

[0064] In this embodiment, when the workpiece is located at the positioning station 301, the first positioning member 11 of the first positioning component 1 moves along the first horizontal direction X to position the first side and the second side of the workpiece, and the third positioning member 21 of the second positioning component 2 moves along the second horizontal direction Y to position the third side and the fourth side of the workpiece. In this way, on one positioning station, the first positioning member 11 and the second positioning member 12 can position the first side and the second side of the workpiece in the first horizontal direction X, and the third positioning member 21 and the fourth positioning member 22 can position the third side and the fourth side of the workpiece in the second horizontal direction Y. Positioning the workpiece on one positioning station can avoid the phenomenon of loss of positioning accuracy when the workpiece is positioned at two positioning stations respectively. For example, the workpiece is first positioned at the first positioning station for the first side and the second side of the workpiece. After positioning, a manipulator is used to transport the workpiece to the second positioning station, and then the third side and the fourth side of the workpiece are positioned at the second positioning station. At this time, when the manipulator transports the workpiece from the first positioning station to the second positioning station, it cannot be guaranteed that the workpiece will not move, so it cannot be guaranteed that the positioning accuracy of the first side and the second side of the workpiece when it is at the first positioning station will not change.

[0065] In addition, by adopting the solution of this embodiment, on the one hand, the first positioning component 1 positions the first side and the second side of the workpiece along the first horizontal direction X, while the second positioning component 2 positions the third side and the fourth side of the workpiece along the second horizontal direction Y perpendicular to the first horizontal direction X. This design of two directions and two components ensures the accurate fixation of the workpiece in the plane and improves the detection accuracy. On the other hand, the design of the first positioning member 11 reciprocating along the first horizontal direction X and the third positioning member 21 reciprocating along the second horizontal direction Y enables the positioning mechanism to adapt to workpieces of different sizes and specifications, enhancing the versatility and flexibility. For workpieces of large or small sizes, accurate positioning can be achieved by adjusting the positions of the first positioning member 11 and the third positioning member 21.

[0066] It should be noted that in addition to the first positioning member 11 of the first positioning component 1 being able to reciprocate along the first horizontal direction X, it is also possible that while the first positioning member 11 reciprocates along the first horizontal direction X, the second positioning member 12 can also reciprocate along the first horizontal direction X. Similarly, the fourth positioning member 22 of the second positioning component 2 can also reciprocate along the second horizontal direction X. This embodiment does not make specific limitations on this.

[0067] Furthermore, referring to Figure 1 , the positioning mechanism 100 further includes a first driving component 13. The first driving component 13 is connected to the first positioning member 11 to drive the first positioning member 11 to move relative to the second positioning member 12 along the first horizontal direction X. It should be noted that the first driving component 13 is not only connected to the first positioning member 11, but also connected to the second positioning member 12. Or, the first driving component 13 is connected to the second positioning member 12 to drive the second positioning member 12 to move relative to the first positioning member 11 along the first horizontal direction X. That is to say, the first driving component 13 only drives the first positioning member 11 to move along the first horizontal direction X, or the first driving component 13 only drives the second positioning member 12 to move along the first horizontal direction X, or the first driving component 13 drives the first positioning member 11 and the second positioning member 12 to move simultaneously, approaching or moving away from each other along the first horizontal direction X.

[0068] Driving the positioning member to move along the first horizontal direction X through the first driving component 13 realizes the automatic movement of the positioning member without manual adjustment of the position. This not only reduces the labor intensity of the operator, but also significantly improves the work efficiency. The automatic positioning of the first driving component 13 can accelerate the turnover speed of the workpiece and improve the overall production efficiency.

[0069] It can be understood that the first driving component 13 can be a motor or a cylinder, etc. Exemplarily, when the first driving component 13 is a motor, since the motor usually has stable output characteristics and good durability, it can maintain stable performance under long-term and high-frequency use. Therefore, using the motor to drive the positioning member to reciprocate along the first horizontal direction X ensures the stability and reliability of the positioning member during the positioning process, and can reduce the downtime and production losses caused by failures.

[0070] In some embodiments, referring to Figure 1 , the positioning mechanism 100 further includes a second driving component 23, and the second driving component 23 is connected to the third positioning member 21 to drive the third positioning member 21 to move along the second horizontal direction Y. Similarly, similar to the first driving component 13, the second driving component 23 is not only connected to the third positioning member 21, but the second driving component 23 is also connected to the fourth positioning member 22, or the second driving component 23 is simultaneously connected to the third positioning member 21 and the fourth positioning member 22. That is to say, the second driving component 23 not only drives the third positioning member 21 to move relative to the fourth positioning member 22 along the second horizontal direction X, but also enables the second driving component 23 to drive the fourth positioning member 22 to move relative to the third positioning member 21 along the second horizontal direction Y, or the second driving component 23 can be connected to the third positioning member 21 and the fourth positioning member 22 to drive the third positioning member 21 and the fourth positioning member 22 to move simultaneously, approaching or separating from each other along the second horizontal direction Y. Using the second driving component 23 to drive the third positioning member 21 to move along the second horizontal direction Y can ensure the stability and reliability of the third positioning member 21 during the positioning process. At the same time, the second driving component 23 realizes the automatic movement of the third positioning member 21, and can avoid misoperations when manually operating the movement of the third positioning member 21. Here, the second driving component 23 is similar in structure to the first driving component 13 in the above embodiments, and will not be elaborated in this embodiment.

[0071] Optionally, as Figure 1As shown, the first positioning component 1 further includes a first slide rail 14 and a first slider 15. The first slide rail 14 is arranged on the base 6 along the first horizontal direction X. The first slider 15 is arranged on the first positioning member 11. The first positioning member 11 is slidably connected to the first slide rail 14 through the first slider 15, so that the first positioning member 11 can move along the first horizontal direction X. The second positioning component 2 further includes a second slide rail 24 and a second slider 25. The second slide rail 24 is arranged on the base 6 along the second horizontal direction Y. The second slider 25 is arranged on the third positioning member 21. The third positioning member 21 is slidably connected to the second slide rail 24 through the second slider 25, so that the third positioning member can move along the second horizontal direction Y. It should be noted that the first slider 15 can also be arranged on the second positioning member 12, and the second positioning member 12 is slidably connected to the first slide rail 14 through the first slider 15, or the first slider 15 can also be arranged on the first positioning member 11 and the second positioning member 12, and both the first positioning member 11 and the second positioning member 12 are slidably connected to the first slide rail 14 through the first slider 15. Similarly, the second slider 25 can also be arranged on the fourth positioning member 22, and the fourth positioning member 22 is slidably connected to the second slide rail 24 through the second slider 25, or the second slider 25 can also be arranged on the third positioning member 21 and the fourth positioning member 22 at the same time, and both the third positioning member 21 and the fourth positioning member 22 are slidably connected to the second slide rail 24 through the second slider 25 at the same time. That is to say, the first positioning member 11 is slidably connected to the first slide rail 14 through the first slider 15, so that the first positioning member 11 can move relative to the second positioning member 12 along the first horizontal direction X, or the first positioning member 11 and the second positioning member 12 are slidably connected to the first slide rail 14 through the first slider 15, so that the first positioning member 11 and the second positioning member 12 can approach or move away from each other along the first horizontal direction X.

[0072] In this way, the positioning member realizes movement by the way of sliding connection between the slide rail and the slider, which can make the positioning member move along the preset direction, and can ensure the accuracy and stability of the positioning member during the movement. In addition, the structures of the slide rail and the slider are relatively simple, easy to clean and maintain. When needed, the worn parts can be conveniently replaced to ensure the continuous and stable operation of the equipment.

[0073] In some embodiments, such as Figure 1 and Figure 2As shown in the figure, the first slider 15 includes a first positioning slider 151 and a second positioning slider 152. The first positioning slider 151 is arranged on the first positioning member 11, and the second positioning slider 152 is arranged on the second positioning member 12. The first driving member 13 includes a first pulley 17, a second pulley 18, a first fixing plate 171 and a second fixing plate 181. The first pulley 17 and the second pulley 18 are arranged at intervals along the first horizontal direction X on both sides of the base 6. The first pulley 17 and the second pulley 18 are connected by a belt. The first fixing plate 171 and the second fixing plate 181 are installed on the belt. The first fixing plate 171 is fixedly connected to the first positioning slider 151, and the second fixing plate 181 is fixedly connected to the second positioning slider 152. The first pulley 17 and the second pulley 18 rotate synchronously, and the belt drives the first positioning slider 151 and the second positioning slider 152 to reciprocate along the first horizontal direction X, so that the first positioning member 11 and the second positioning member 12 approach or move away from each other.

[0074] Further, the second slider 25 includes a third positioning slider 251 and a fourth positioning slider 252. The third positioning slider 251 is arranged on the third positioning member 21, and the fourth positioning slider 252 is arranged on the fourth positioning member 22. The second driving member 23 includes a third pulley 27, a fourth pulley 28, a third fixing plate 271 and a fourth fixing plate 281. The third pulley 27 and the fourth pulley 28 are arranged at intervals along the second horizontal direction Y on both sides of the base 6. The third pulley 27 and the fourth pulley 28 are connected by a belt. The third fixing plate 271 and the fourth fixing plate 281 are installed on the belt. The third fixing plate 271 is fixedly connected to the third positioning slider 251, and the fourth fixing plate 281 is fixedly connected to the fourth positioning slider 252. The third pulley 27 and the fourth pulley 28 rotate synchronously, and the belt drives the third positioning slider 251 and the fourth positioning slider 252 to reciprocate along the second horizontal direction Y, so that the third positioning member 21 and the fourth positioning member 22 approach or move away from each other.

[0075] In this way, since the first pulley 17 and the second pulley 18, as well as the third pulley 27 and the fourth pulley 28 are respectively connected by belts, they can ensure the synchronous movement of the first positioning slider 151 and the second positioning slider 152, as well as the third positioning slider 251 and the fourth positioning slider 252, so that when the first pulley 17 and the second pulley 18 rotate, the first positioning member 11 and the second positioning member 12 approach or move away synchronously. Similarly, when the third pulley 27 and the fourth pulley 28 rotate, the third positioning member 21 and the fourth positioning member 22 can approach or move away synchronously. This synchronism ensures that the relative position relationship of the positioning members remains consistent during the movement. By using pulley and belt drive, the relative positions between the first positioning member 11 and the second positioning member 12, as well as the third positioning member 21 and the fourth positioning member 22 can be precisely controlled. Due to the smoothness and predictability of belt drive, it helps to meet the high-precision positioning requirements. In addition, the maintenance of the belt drive system is relatively simple, and it is also easier to replace the belt or adjust the drive parameters, which reduces the maintenance cost and time cost of the equipment.

[0076] In some embodiments, as Figure 2 shown, the first positioning assembly 1 further includes a first position sensor 16, and the first position sensor 16 includes an induction end and an output end. The induction end of the first position sensor 16 is connected to the first positioning member 11, and the output end of the first position sensor 16 is electrically connected to the first driving member 13. The output end of the first position sensor 16 outputs the position information sensed by the induction end of the first position sensor 16 to the first driving member 13 to control the reciprocating movement of the first positioning member 11. At the same time, the second positioning assembly 2 further includes a second position sensor 26, and the second position sensor 26 includes an induction end and an output end. The induction end of the second position sensor 26 is connected to the third positioning member 21, and the output end of the second position sensor 26 is electrically connected to the second driving member 23. The output end of the second position sensor 26 outputs the position information sensed by the induction end of the second position sensor 26 to the second driving member 23 to control the reciprocating movement of the third positioning member 21.

[0077] In this way, when positioning the workpiece, during the movement of the first positioning member 11 and the third positioning member 21, the first position sensor 16 and the second position sensor 26 can sense the position information of the first positioning member 11 and the third positioning member 21 in real time, and transmit this information to the first driving member 13 and the second driving member 23 through the output end, so as to accurately grasp the position states of the first positioning member 11 and the third positioning member 21. Moreover, through the electrical connection with the driving member, the first position sensor 16 or the second position sensor 26 realizes the closed-loop control of the movement of the first positioning member 11 or the third positioning member 21. When it is detected that the first positioning member 11 or the third positioning member 21 deviates from the predetermined position, the system can immediately adjust the output of the first driving member 13 or the second driving member 23, so that the first positioning member 11 or the third positioning member 21 quickly returns to the correct position, thereby improving the accuracy and stability of positioning. In addition, the first position sensor 16 and the second position sensor 26 can realize the automatic acquisition and processing of position information, enabling the system to achieve automatic control, reducing manual operations, improving production efficiency, and reducing operation errors.

[0078] Further, referring to Figure 1 and Figure 2 , the positioning mechanism 100 further includes a lifting module 3, and the lifting module 3 is connected to the second positioning member 12 to drive the second positioning member 12 to lift. After the workpiece is positioned, it is necessary to move the workpiece out of the positioning station 301 along the first horizontal direction X. At this time, the lifting module 3 needs to drive the second positioning member 12 to rise to prevent the workpiece from colliding with the second positioning member 12 during the process of moving out of the positioning station 301, thereby causing damage to the surface of the workpiece.

[0079] In some embodiments, in combination with Figure 1 and Figure 2 , the first positioning assembly further includes a connecting member 19. The second positioning member 12 is connected to the base 6 through the connecting member 19. The lifting module 3 includes a driving member 31 and a connecting plate 32. The connecting plate 32 is connected to the connecting member 19. The driving member 31 is fixedly connected to the connecting plate 32. The second positioning member 12 is connected to the driving member 31, and the driving member 31 drives the second positioning member 12 to move in the vertical direction. Through the control of the driving member 31, it can be ensured that the movement of the second positioning member 12 in the vertical direction is accurate and error-free, thereby improving the working efficiency of the entire system. The connecting plate 32 is arranged on the connecting member 19 connected to the base 6, which provides a solid support for the entire lifting module 3, enhances the stability of the lifting module 3, and reduces the deviation and error caused by vibration or external force.

[0080] It should be noted that the driving member 31 can be a motor or a cylinder, and this embodiment does not make specific limitations thereto. Exemplarily, the driving member 31 is a cylinder. After the workpiece is positioned, the cylinder acts to raise the second positioning member 12 by a certain height, so that the workpiece can be removed from the positioning station 301 without colliding with the second positioning member 12. Using a cylinder to control the lifting of the second positioning member 12 can, after the workpiece is positioned, ensure that the second positioning member 12 is raised to exactly the height allowing the workpiece to be removed by precisely controlling the stroke of the cylinder, thus avoiding collision with the workpiece and ensuring the smoothness of the operation.

[0081] In some embodiments, the height of the first positioning member 11 needs to be lower than that of the second positioning member 12. On the one hand, the feeding direction of the workpiece is the same as the first horizontal direction X. When the workpiece is fed, it is fed from one side of the first positioning member 11. Setting the height of the first positioning member 11 lower than that of the second positioning member 12 facilitates the feeding of the workpiece from one side of the first positioning member 11 and prevents the workpiece from colliding with the first positioning member 11 during feeding. On the other hand, initially positioning with the first positioning member 11 of lower height and then precisely fixing with the second positioning member 12 of higher height helps to gradually reduce the positioning error of the workpiece and improve the final positioning accuracy.

[0082] In some embodiments, as Figure 1 shown, the heights of the first positioning member 11 and the second positioning member 12 are higher than the heights of the third positioning member 21 and the fourth positioning member 22. In other words, the horizontal plane where the first positioning member 11 and the second positioning member 12 of the first positioning assembly 1 are located is staggered up and down from the horizontal plane where the third positioning member 21 and the fourth positioning member 22 of the second positioning assembly 2 are located, and the horizontal plane where the first positioning member 11 and the second positioning member 12 are located is above the horizontal plane where the third positioning member 21 and the fourth positioning member 22 are located. This can avoid the third positioning member 21 and the fourth positioning member 22 interfering with or even colliding with the first positioning member 11 and the second positioning member 12 during the process of clamping the workpiece when positioning small-sized workpieces, and can extend the service life of the positioning mechanism 100.

[0083] In some embodiments, as Figure 1As shown, the positioning mechanism 100 further includes a plurality of positioning posts 4. A plurality of mounting through holes 5 are provided on the first positioning member 11, the second positioning member 12, the third positioning member 21 and the fourth positioning member 22. The mounting through holes 5 are used to mount the positioning posts 4, and the positioning posts 4 contact the workpiece to complete positioning. On the one hand, through the contact of the plurality of positioning posts 4 with the workpiece, multi-point positioning is achieved. Compared with single-point or few-point positioning, multi-point positioning can more evenly disperse the binding force received by the workpiece, reduce deformation or deviation caused by uneven single-point force, thereby improving the positioning accuracy; on the other hand, the simultaneous action of the plurality of positioning posts 4 makes the workpiece more stable during the positioning process and is not easily affected by external factors. The position changes, ensuring the accuracy of the detection result after positioning.

[0084] Further, the plurality of mounting through holes 5 are arranged at intervals of 10 mm to adapt to different sizes of workpieces. Different workpieces may require different positioning points. Arranging the plurality of mounting through holes 5 at intervals of 10 mm can adapt to workpieces of various shapes and sizes. When positioning different workpieces, according to the size of the workpiece, the positioning posts 4 are installed on the mounting through holes 5 arranged at intervals. It should be noted that one positioning post 4 is correspondingly installed in one mounting through hole 5, and there may be no mounting through hole 5 or at least one mounting through hole 5 between every two adjacent positioning posts 4 to match the size of the workpiece, and then position the workpiece, which enhances the versatility and applicability of the positioning mechanism.

[0085] Optionally, the positioning posts 4 on the first positioning member 11 and the second positioning member 12 are arranged downward along the vertical direction, and the positioning posts 4 on the third positioning member 21 and the fourth positioning member 22 are arranged upward along the vertical direction. In this way, by arranging the positioning posts 4 in the upper and lower directions, the height difference between the first positioning assembly 1 and the second positioning assembly 2 can be compensated, and a more comprehensive constraint can be formed on the workpiece during positioning. The simultaneous positioning in the upper and lower directions reduces the freedom degree of the workpiece in the vertical direction, thereby enhancing the stability of the positioning. At the same time, because the positioning posts 4 are arranged at intervals, arranging the positioning posts 4 in the upper and lower directions also helps to prevent the positioning posts 4 on the first positioning member 11 and the second positioning member 12 from interfering with the positioning posts 4 on the third positioning member 21 and the fourth positioning member 22 when positioning a workpiece with a smaller size.

[0086] Participate Figure 3 and Figure 4 , Figure 3 is a schematic structural diagram of the detection device disclosed in the embodiment of the present application, Figure 4 is Figure 3Top view of the detection device. The present application discloses a detection device 300, which includes a positioning station 301, a code reading station 302, a detection station 303, a carrier module 304, and a positioning mechanism 100 as described in the foregoing embodiments. The positioning station 301 is used to position the workpiece, the code reading station 302 is used to read the identification code of the workpiece, the detection station 303 is used to detect the workpiece, and the carrier module 304 is used to carry the workpiece. Moreover, the carrier module 304 can drive the workpiece to move from the positioning station 301 to the code reading station 302 and from the code reading station 302 to the detection station 303. The detection device 300 adopting the positioning mechanism 100 can detect the workpiece while ensuring the positioning accuracy, improving the detection accuracy. At the same time, the positioning mechanism 100 can complete the positioning on the positioning station 301, without the need to position the workpiece successively on two stations, avoiding the loss of the positioning accuracy of the workpiece due to the transportation between the two positioning stations, improving the positioning accuracy, and further improving the detection efficiency.

[0087] In some embodiments, as Figure 5 shown, the carrier module includes a carrier table 3041 and a rotation driving component 3042. The carrier table 3041 is used to carry the workpiece, and the rotation driving component 3042 is connected to the carrier table 3041 to drive the carrier table 3041 to rotate. When the workpiece is transported from the code reading station 302 to the detection station 303, it is necessary to detect the four sides of the workpiece. The carrier table 3041 rotates driven by the rotation driving component 3042, so as to realize the rotation of the workpiece on the carrier table 3041 at the detection station 303 to detect the four sides of the workpiece. Using the rotation driving component 3042 to drive the carrier table 3041 to rotate, on the one hand, it can realize the rotational positioning of the carrier table 3041 and the workpiece thereon through the control of the rotation driving component 3042, which is suitable for workpieces that need to be detected at multiple angles; on the other hand, compared with manually rotating the carrier table 3041, driving the carrier table 3041 to rotate by the rotation driving component 3042 can significantly reduce the error during the rotation process and improve the detection accuracy.

[0088] Exemplarily, the rotation driving component 3042 can be a motor, and the motor can ensure the stability and reliability of driving the carrier table 3041 to rotate.

[0089] Furthermore, referring to Figure 5 , an adsorption disk 3041a is provided on the carrier table 3041, and the adsorption disk 3041a is used to adsorb the workpiece on the carrier table 3041. Using the adsorption disk 3041a to fix the workpiece on the carrier table 3041 is relatively stable, which can avoid the position deviation of the workpiece during the movement between the positioning station 301, the code reading station 302, and the detection station 303, thus affecting the final detection result. At the same time, adsorbing the workpiece by the adsorption disk 3041a can also prevent the workpiece from falling off the carrier table 3041 during the rotation of the carrier table 3041.

[0090] In some embodiments, referring to Figure 5 , the detection device 300 further includes a support frame 305 and a barcode reader 306. The support frame 305 is fixedly arranged above the positioning mechanism 100, and the barcode reader 306 is installed on the support frame 305 for identifying the workpiece located at the barcode reading station 302. Installing the barcode reader 306 on the support frame 305, and the support frame 305 is fixedly arranged above the positioning mechanism 100. The support frame 305 provides a stable installation foundation for the barcode reader 306. Such a layout makes the structure of the detection device 300 more compact, and the floor area of the device is smaller. At the same time, using the barcode reader 306 to read the barcode of the workpiece reduces manual intervention, which can not only save labor costs but also significantly improve work efficiency. The barcode reading station 302 is located between the positioning station 301 and the detection station 303. The barcode of the workpiece can be read when the workpiece is moved out of the positioning station 301, which can improve the detection efficiency of the detection device 300.

[0091] The detection process of the detection device 300 of the present application will be briefly described below:

[0092] First, when the carrier module 304 is located at the positioning station 301, the workpiece is loaded onto the carrier 3041 from one side of the first positioning member 11 of the positioning mechanism 100, and the adsorption disk 3041a is used to fix the workpiece;

[0093] Secondly, the positioning mechanism 100 positions the workpiece on the carrier 3041, that is, the first positioning member 11 and the second positioning member 12 of the positioning mechanism 100 move simultaneously along the first horizontal direction X under the drive of the first driving member 13, and the third positioning member 21 and the fourth positioning member 22 move simultaneously along the second horizontal direction Y under the drive of the second driving member 23, so that the first positioning member 11 and the second positioning member 12 approach each other along the first horizontal direction X, and the third positioning member 21 and the fourth positioning member 22 approach each other along the second horizontal direction Y to complete the positioning of the workpiece;

[0094] Furthermore, after the positioning mechanism 100 completes the positioning of the workpiece, the second positioning member 12 is raised to a certain height under the drive of the driving member 31, and then the carrier 3041 drives the workpiece to move from the positioning station 301 to the detection station 303 along the first horizontal direction X. During the movement, the barcode reader 306 identifies the workpiece passing through the barcode reading station 302;

[0095] Finally, the carrier 3041 drives the workpiece to move to the detection station, and the rotation driving member 3042 drives the carrier 3041 to rotate to complete the detection of the four sides of the workpiece. After the workpiece is detected, the carrier 3041 drives the workpiece to move back to the positioning station 301 to unload the workpiece.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
