[0033] Referring to Figure 2 and Figure 3 As shown, the positioning and overturning mechanism 2 comprises a base 21, an overturning plate 22, a connecting shaft 28, a positioning assembly 23, a first driving assembly 24 and a second driving assembly 25. The base 21 is installed on the bottom plate 11, and the overturning plate 22 is rotatably connected with the base 21 through the connecting shaft 28. The positioning assembly 23 is rotatably arranged on the overturning plate 22 and used for positioning the workpiece to be processed 100. The first driving assembly 24 is arranged on the bottom plate 11 and connected with the overturning plate 22, and used for driving the overturning plate 22 to overturn around the length direction of the overturning plate 22 to drive the positioning assembly 23 to make overturning movement. The second driving assembly 25 is arranged on the overturning plate 22 and connected with the positioning assembly 23, and used for driving the positioning assembly 23 to rotate around an axis perpendicular to the overturning plate 22. The first driving assembly 24 can comprise a servo motor which can drive the overturning plate 22 to rotate by any angle within 180°.

[0034] When processing the workpiece to be processed 100, the workpiece to be processed 100 can be positioned by the positioning assembly 23, then the overturning plate 22 is driven by the first driving assembly 24 to make overturning movement to drive the workpiece to be processed 100 to overturn to a suitable inclined position, then the workpiece to be processed 100 is processed by the processing mechanism 3, then the positioning assembly 23 is driven by the second driving assembly 25 to rotate to drive the workpiece to be processed 100 to rotate by a certain angle, and the workpiece to be processed 100 is continuously processed by the processing mechanism 3, so as to complete the processing operation of the workpiece to be processed 100. The present application can automatically overturn and position small workpieces such as shrapnel by the positioning and overturning mechanism 2, and can realize efficient automatic production by cooperating with devices such as laser welding machines and code scanning guns, reduce the labor intensity of workers and improve the production efficiency. Meanwhile, the positioning and overturning mechanism 2 is designed as a modular structure as a whole, and can form a system by cooperating with various automatic devices and assemblies.

[0035] Referring to Figure 4 As shown in the figure, the positioning assembly 23 comprises a positioning member 231, an adsorption plate 232, a plurality of vacuum suction cups 233 and a ventilation pipe 234. The positioning member 231 comprises a positioning portion 231b and a connecting convex column 231c. The positioning portion 231b is arranged on one side of the turnover plate 22, and the positioning portion 231b is provided with a positioning groove 231a. The adsorption plate 232 is provided with a plurality of adsorption holes 232a, and the adsorption plate 232 is arranged in the positioning groove 231a, so that the adsorption plate 232 and the bottom wall of the positioning groove 231a form a vacuum cavity. The plurality of vacuum suction cups 233 are arranged on the adsorption plate 232 and located at the adsorption holes 232a. The connecting convex column 231c is connected with the positioning portion 231b, and the connecting convex column 231c is rotatably arranged in the turnover plate 22. The connecting convex column 231c is provided with an airflow passage, and the airflow passage is communicated with the vacuum cavity. The ventilation pipe 234 is connected with the connecting convex column 231c, and the ventilation pipe 234 can be connected with an external vacuum equipment. When the workpiece 100 to be processed is placed in the positioning groove 231a, the external vacuum equipment can be used to suck air, so as to realize the adsorption and fixation of the workpiece 100 to be processed by the vacuum suction cups 233.

[0036] In this embodiment, the positioning member 231 is rotatably connected with the turnover plate 22, and a special positioning groove 231a is designed on the positioning member 231 according to the processing requirements of the product. The adsorption plate 232 is arranged in the positioning groove 231a, so that the positioning, rotation and vacuum adsorption are combined into one, the positioning effect is improved, and the product structure is simplified.

[0037] Referring to Figure 5 As shown in the figure, the second driving assembly 25 comprises a driving cylinder 251, a sliding plate 252, a steering yoke 253 and a connecting member 254. The steering yoke 253 is sleeved on the connecting convex column 231c. The sliding plate 252 is slidably arranged on the side of the turnover plate 22 away from the positioning portion 231b. One end of the connecting member 254 is connected with the sliding plate 252, and the other end of the connecting member 254 is limited with the steering yoke 253. The driving cylinder 251 is arranged on the turnover plate 22, and the driving cylinder 251 is connected with the sliding plate 252, for driving the sliding plate 252 to move linearly, so as to drive the positioning member 231 to rotate around the axis perpendicular to the turnover plate 22. The maximum rotation angle of the steering yoke 253 is 110°. When the positioning member 231 is driven to rotate, the rotation angle of the positioning member 231 can be adjusted by controlling the moving distance of the sliding plate 252.

[0038] In this embodiment, the sliding plate 252 is driven to move linearly by the driving cylinder 251, and then the sliding plate 252 drives the steering yoke 253 to rotate, so as to drive the positioning member 231 to rotate around the axis perpendicular to the turnover plate 22. The driving structure is simple and stable.

[0039] Continuing to refer to Figure 5As shown, the positioning and flipping mechanism 2 further includes a slide rail 26 and a plurality of sliders 27. The slide rail 26 is disposed on the side of the flip plate 22 facing away from the positioning portion 231b. The plurality of sliders 27 are slidably connected to the slide rail 26. The sliding plate 252 is connected to the plurality of sliders 27, thereby enabling the sliding plate 252 to move relative to the flip plate 22 along the length direction of the slide rail 26. In this embodiment, the provision of the slide rail 26 and the sliders 27 reduces friction during movement of the sliding plate 252, thereby making the movement of the sliding plate 252 smoother.

[0040] In some embodiments, the second drive assembly 25 may further include a buffer and a vacuum sensor. The buffer and the sliding plate 252 are both located on the same side of the flip plate 22. The buffer is used to cushion the movement of the sliding plate 252, thereby preventing the sliding plate 252 from being damaged due to excessive speed during movement. The vacuum sensor is located on the positioning member 231 and is used to confirm whether there is material in the positioning groove 231a.

[0041] Continue to refer to Figure 3 As mentioned above, there are multiple positioning assemblies 23. In this embodiment, there are five positioning assemblies 23. The multiple positioning assemblies 23 are spaced apart along the length of the flip plate 22, and the sliding plate 252 is connected to each positioning assembly 23. When the first drive assembly 24 drives the flip plate 22 to flip, it can drive each positioning assembly 23 to flip synchronously. When the drive cylinder 251 drives the sliding plate 252 to move linearly, it can drive each positioning assembly 23 to rotate synchronously.

[0042] Continue to refer to Figure 1 As shown, the processing mechanism 3 includes a servo slide 31 and a processing component 32. The servo slide 31 is arranged on the support 12, and the processing component 32 is arranged on the servo slide 31, so that the servo slide 31 can drive the processing component 32 to move along the length direction of the flip plate 22 to realize the processing of the workpiece 100 to be processed positioned by each positioning component 23 in sequence, such as scanning, welding, marking, etc.

[0043] The application takes the machining assembly 32 as an example to illustrate the code scanning process. When scanning the code, the mechanical hand can take out the plurality of materials (workpieces to be machined) welded from the tray and place them in the positioning groove 231a of each positioning assembly 23, and then start the device. The overturning plate 22 is driven to overturn to a preset inclined position by the servo motor, so that the side of each material is perpendicular to the code scanning lens. Then, the code scanning lens is driven to move along the arrangement direction of each positioning assembly 23 under the action of the servo sliding table 31, so that the code scanning lens scans each material in turn. After the first group of two-dimensional code scanning is completed, the driving cylinder 251 is extended, the sliding plate 252 is driven to move linearly, and the sliding plate 252 drives the steering yoke 253 to rotate in the movement process, so as to drive the positioning assembly 23 and the material to rotate 90°, so that the second group of two-dimensional code is perpendicular to the code scanning lens. Then, the code scanning lens scans each material in turn. After the second group of two-dimensional code scanning is completed, the servo motor returns to the original position, so that the material is placed horizontally. Then, the mechanical hand takes back the material and places the unscanned material again. The above process is repeated to complete the scanning of all materials. The application can position five materials at a time, which improves the production efficiency. Moreover, the automatic code scanning replaces manual code scanning, which further improves the production efficiency.

[0044] The above is only the preferred embodiment of the application, but the protection scope of the application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
