[0057] In the embodiment, by arranging multiple independent trays 2 on the material platform 1, the corresponding materials can be conveniently stored in each tray 2, and then the overturning unit 4 can be adjusted and aligned to different trays 2 through the horizontal movement of the moving platform 3, and the overturning of the tray can be realized through the contact between the overturning unit 4 and the tray 2 and the up-down operation of the overturning unit 4, thereby effectively improving the automation degree and overturning efficiency of the application.

[0059] According to an embodiment of the application, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , the overturning unit 4 comprises a support seat 41, an arc-shaped tooth adjusting structure 42, a flexible needle structure 43 and a first driving device 44. In the embodiment, the arc-shaped tooth adjusting structure 42 and the first driving device 44 are installed on the support seat 41; the flexible needle structure 43 is arranged on the arc-shaped tooth adjusting structure 42 and used for connecting with the lifting control end of the tray 2. In the embodiment, the first driving device 44 is connected with the arc-shaped tooth adjusting structure 42 and used for adjusting the height of the flexible needle structure 43. In the embodiment, the first driving device 44 can be realized by an electric motor, and the lifting height of the arc-shaped tooth adjusting structure 42 can be accurately controlled through the rotation speed of the controller, so as to accurately control the inclination angle of the tray 2.

[0060] According to an embodiment of the application, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , the arc-shaped tooth adjusting structure 42 comprises an arc-shaped rack 421, a driving gear 422, a guide wheel 423 and an eccentric wheel 424. In the embodiment, the guide wheel 423 and the eccentric wheel 424 are arranged on the opposite sides of the arc-shaped rack 421 in the radial direction and abut against the arc-shaped rack 421 respectively; and the arc-shaped rack 421 is arranged in mesh with the driving gear 422 on one side in the radial direction. In the embodiment, the flexible needle structure 43 is connected with the upper end of the arc-shaped rack 421.

[0061] According to an embodiment of the application, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, according to an embodiment of the present application, the driving gear 422 is arranged to mesh with the radially outer side of the arc-shaped rack 421, the guide wheel 423 is arranged on the same side of the driving gear 422 relative to the arc-shaped rack 421, and the driving gear 422 and the guide wheel 423 are spaced apart above the guide wheel 423. In this embodiment, the driving gear 422, the guide wheel 423 and the eccentric guide wheel 424 are arranged in a triangular shape, thereby achieving connection with the arc-shaped rack 421 and three-point positioning of the arc-shaped rack 421, effectively ensuring the positioning stability of the arc-shaped rack 421 and the operation precision of the arc-shaped rack 421. In this embodiment, two meshing racks 421a are arranged side by side on the radially outer side of the arc-shaped rack 421, and a groove-shaped structure for positioning is formed between the two meshing racks 421a. In this embodiment, the meshing rack 421a is used to mesh with the driving gear 422, thereby achieving accurate control of the movement position of the arc-shaped rack 421.

[0062] In this embodiment, the driving gear 422 includes an intermediate limiting portion 422a and meshing gear portions 422b arranged coaxially on both sides of the intermediate limiting portion 422a. The intermediate limiting portion 422a is in the form of a circular plate-shaped body, and its radial dimension is greater than the radial dimension of the meshing gear portions 422b, thereby achieving a protruding arrangement, and the driving gear 422 forms a combined gear structure with a protruding intermediate portion. In this embodiment, the axial thickness of the protruding portion of the intermediate limiting portion 422a is consistent with the spacing between the two meshing racks 421a, so as to be embedded between the two meshing racks 421a and achieve rolling contact with the radially outer side of the arc-shaped rack 421. Through the above arrangement, the driving gear 422 effectively has an axial limiting effect, thereby further achieving stable positioning of the arc-shaped rack 421.

[0063] In this embodiment, the meshing gear portions 422b are connected to the meshing racks 421a.

[0064] In the embodiment, the meshing gear portion 422b and the intermediate limiting portion 422a are coaxially sleeved on the rotating shaft of the first driving device 44 in sequence. In order to ensure the installation stability of the meshing gear portion 422b, a locking connection assembly is arranged on the outer side of the meshing gear portion 422b away from the first driving device 44 to achieve the fixed installation of the meshing gear portion 422b. In the embodiment, the locking connection assembly comprises a long strip-shaped connecting plate body and a threaded connecting piece. Three through holes are arranged on the long strip-shaped connecting plate body (of course, other numbers can be arranged, and the positions can be adjusted according to actual needs). Correspondingly, threaded holes are arranged on the meshing gear portion 422b (that is, any meshing gear portion 422b on the two sides of the intermediate limiting portion 422a) and the rotating shaft of the first driving device 44 that need to be connected. After the three through holes on the connecting plate body are aligned with the threaded holes, the threaded connecting piece is used to connect and fix them. Through the locking connection assembly and the multi-position fixing mode, the looseness caused by long-time operation is effectively avoided, and the operation accuracy and stability of the arc-shaped tooth adjusting structure 42 are more effectively ensured.

[0065] In the embodiment, due to the protruding arrangement of the intermediate limiting portion 422a, the radial outer side surface thereof can abut against the bottom surface of the groove-shaped structure formed at the middle position of the arc-shaped rack 421 (that is, the radial outer side surface of the arc-shaped rack 421), thereby achieving the stable meshing and limiting of the driving gear 422 to the arc-shaped rack 421. In the embodiment, the radial outer side surface of the intermediate limiting portion 422a can be arranged as a plane or a conical surface, and the abutting positions on the arc-shaped rack 421 can be correspondingly matched. In particular, when the outer side surface of the intermediate limiting portion 422a is arranged as a conical surface, it has a certain self-positioning effect on the arc-shaped rack 421, thereby benefiting the stable operation of the arc-shaped rack 421.

[0066] In the embodiment, the guide wheel 423 is embedded between the two meshing racks 421a, and the axial thickness of the embedded part of the guide wheel 423 is consistent with the interval between the meshing racks 421a. In the embodiment, the radial outer side surface of the guide wheel 423 also abuts against the bottom surface of the groove-shaped structure formed between the two meshing racks 421a, thereby benefiting the stable support of the arc-shaped rack 421. In addition, the radial outer side surface of the guide wheel 423 can be arranged as a plane or a conical surface, and the abutting positions on the arc-shaped rack 421 can be correspondingly matched. In particular, when the radial outer side surface of the guide wheel 423 is arranged as a conical surface, it has a certain self-positioning effect on the arc-shaped rack 421, thereby benefiting the stable operation of the arc-shaped rack 421.

[0067] In the embodiment, the radially inner side of the arc-shaped rack 421 is provided with an embedded groove 421b, and the eccentric roller 424 is embedded in the embedded groove 421b. In the embodiment, the radially outer side surface of the eccentric roller 424 is in contact with the bottom of the embedded groove 421b, so as to limit the arc-shaped rack 421. In addition, the radially outer side surface of the eccentric roller 424 can be a flat surface or a tapered surface, and the abutting position on the arc-shaped rack 421 can also be matched accordingly. In particular, when the radially outer side surface of the eccentric roller 424 is a tapered surface, it has a certain self-positioning effect on the arc-shaped rack 421, thereby ensuring the stable operation of the arc-shaped rack 421.

[0068] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , according to an embodiment of the present application, the support seat 41 comprises a vertical supporting plate 411 and a horizontal connecting plate 412.

In the embodiment, the first driving device 44 is fixedly connected to the vertical supporting plate 411, and the rotating shaft of the first driving device 44 penetrates the vertical supporting plate 411 and is connected to the driving gear 422. In addition, the first driving device 44 is arranged above the horizontal connecting plate 412.

[0069] In the embodiment, since the driving gear 422 is driven by the first driving device 44, the installation position of the driving gear 422 corresponds to the fixed position of the first driving device 44, and the guide roller 423 and the eccentric roller 424 are rotatably connected to the vertical supporting plate 411 in order to limit the arc-shaped rack 421.

[0070] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, according to an embodiment of the present application, the turnover unit 4 further comprises a photoelectric sensor 45 for detecting the material in the tray 2. In the present embodiment, the photoelectric sensor 45 is fixedly supported on the vertical support plate 411 and is located adjacent to the driving gear 422 on the same side of the vertical support plate 411. In the present embodiment, the photoelectric sensor 45 is connected to the vertical support plate 411 through a sensor support, wherein the sensor support is a plate-shaped body and is fixedly supported on the side of the vertical support plate 411. In the present embodiment, a mounting track is provided on the sensor support, and the photoelectric sensor 45 is connected to the mounting track through a connecting member. In the present embodiment, the mounting track is an arc-shaped track, so that the mounting height and angle of the photoelectric sensor 45 can be adjusted along the track to achieve detection of the tray 2.

In the present embodiment, the spring 434 is located in the mounting cavity 431a; one end of the top rod 433 is in abutment with the spring 434, and the other end is used for mounting the end cap 435.

[0072] In the present embodiment, the needle structure body 431 is in a regular block structure, so as to be conveniently fixedly connected to the upper end of the arc-shaped rack 421. In the present embodiment, the needle structure body 431 has a certain length, and one end thereof is fixedly connected to the upper end of the arc-shaped rack 421, and the other end thereof is arranged in radial extension along the arc-shaped rack 421.

In addition, when the flexible top pin structure 43 is connected with the tray, the spring 434 can be appropriately in a compressed state, and then in the process of driving the tray to overturn, the elastic force of the spring 434 can be used to elastically control the extension length of the top rod 433, so that the tray can be effectively prevented from being separated from the end cap 435 during the overturning process, especially when the tray vibrates or other accidents occur, the stable connection can still be maintained.

Specifically, the sliding rails in the first sliding rail assembly 32 are fixed on the lower side of the material platform 1 in the transverse direction, and two first sliding rail assemblies 32 are arranged in parallel and at intervals to ensure the stability of the connection.

[0080] To further illustrate the present application, the working process of the present application is further described.

[0081] The turnover mechanism of the present application is installed on the corresponding station through the material platform 1 to realize the corresponding sorting operation. In this embodiment, a plurality of trays 2 are arranged side by side along the transverse direction of the material platform 1, and since each tray 2 is independent, each tray 2 can be turned over through the rotating connection end.

[0082] After receiving the system signal, the driving motor 333 of the second driving device 33 drives the gear part 332 to move along the rack part 331, thereby driving the moving support 31 to adjust the relative position of the flexible needle structure 43 of the turnover unit 4 and the tray 2 along the transverse direction of the material platform 1. In this embodiment, during the operation of the moving platform 3, the photoelectric sensor 45 arranged on the turnover unit 4 detects the material in each tray, and when detecting the presence of material, the second driving device 33 stops driving the transverse movement of the moving support 31.

In this embodiment, since the third driving device 35 is a linear telescopic device, the position of the flexible needle structure 43 and the tray 2 can be adjusted according to the telescopic length, so that the flexible needle structure 43 can be stably inserted into the groove on the tray 2 after the third driving device 35 is telescoped to the position;

[0084] Furthermore, the first driving device 44 drives the driving gear 422 in the arc-shaped tooth adjustment structure 42 to rotate, so as to synchronously realize the movement of the arc-shaped rack 421, thereby driving the flexible ejector structure 43 to move upward. In this embodiment, when the flexible ejector structure 43 is inserted into the material tray 2, the center of the arc-shaped rack 421 coincides with the rotation center of the material tray 2 (i.e., the rotation connection position of the rotation connection end), thereby realizing the lifting of the lifting control end of the material tray 2.

[0085] Furthermore, after the control tray 2 is flipped into position and the user removes the material, the first drive device 44 causes the drive gear 422 to run in the opposite direction, causing the lifting control end of the tray 2 to fall back to the initial position. Then, the third drive device 35 starts to run, driving the flipping unit 4 to move away from the tray 2, so that the flexible ejector pin structure 43 is separated from the tray. Then, the aforementioned process is repeated to achieve the flipping action of different trays.

[0086] Of course, if it is necessary to put materials into the material tray, the above-mentioned flipping process can be achieved by selecting the empty material tray 2, which will not be described in detail here.

[0087] The above description is merely an example of a specific solution of the present invention. For any devices and structures not described in detail herein, it should be understood that they are implemented using common devices and methods already available in the art.

[0088] The above description is merely one embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
