[0048] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0049] Reference Figure 1 , 2 As shown, in some embodiments of the present application, an automatic feeding structure is provided, including: a feeding assembly and a pushing assembly. The feeding assembly is used to transfer the workpiece from bottom to top. The pushing assembly is located above the feeding assembly, and the pushing assembly is used to push the workpiece transferred to the downstream position of the feeding assembly away from the feeding assembly, and the workpiece at the downstream position of the feeding assembly is the workpiece lifted to the top of the feeding assembly by the feeding assembly.

[0050] The loading assembly includes a side plate 11, a transmission unit 12, a base 17 and a top plate 18, and the workpiece is loaded on the transmission unit 12. The push assembly includes a drive unit 22 and a push rod 23, and the push rod 23 is installed at the power output end of the drive unit 22. The transmission unit 12 transfers the workpiece to the vicinity of the push rod 23, and the push rod 23 pushes the workpiece away from the transmission unit 12. The base 17 and the top plate 18 are respectively located below and above the side plate 11.

[0051] Specifically, the transmission unit 12 includes a conveyor belt, a baffle 121, and a receiving seat 122. The receiving seat 122 is detachably connected to the conveyor belt and is transferred upward by the conveyor belt. The base 17 and the top plate 18 are respectively arranged at the upstream and downstream ends of the conveyor belt. The baffle 121 is located on one side of the receiving seat 122, and the stop surface of the baffle 121 in contact with the workpiece is parallel to the plane passed by the receiving seat 122. Exemplarily, the conveyor belt includes a driving wheel, a driven wheel, and a motor. The driving wheel and the driven wheel are connected by a transmission chain. The receiving seat 122 is detachably connected to the transmission chain, and the receiving seats 122 are evenly arranged on the transmission chain. The driving wheel is installed on the power output end of the motor, and the driven wheel rotates with the driving wheel through the transmission chain, and the receiving seat 122 installed on the transmission chain can move in a straight line direction. During the movement of the receiving seat 122, the baffle 121 remains stationary, and the workpiece located on the receiving seat 122 will slide on the stop surface of the baffle 121.

[0052] More specifically, the feeding assembly further includes a power unit 13 and an adjusting unit 14. The power unit 13 is传动连接 with the adjusting unit 14, and the adjusting unit 14 drives the baffle 121 to adjust the distance between the baffle 121 and the receiving seat 122. The side plates 11 are located at both ends of the baffle 121 and the receiving seat 122, and the conveyor belt, the power unit 13, and the adjusting unit 14 are installed on the side plates 11.

[0053] Further, the receiving seat 122 has a loading surface 1221, and the baffle 121 is arranged close to the side of the receiving seat 122 adjacent to the loading surface 1221. The loading surface 1221 has a first contact surface and a second contact surface, and the first contact surface and the second contact surface form a V-shaped surface. The workpiece is simultaneously tangent to the first contact surface, the second contact surface, and the stop surface of the baffle 121.

[0054] Reference Figure 5 、 6 As shown, the workpiece includes a first workpiece 31 and a second workpiece 32. The radius of the first workpiece 31 is r1, and the radius of the second workpiece 32 is r2. Among them, the sizes of the first workpiece 31 and the second workpiece 32 are not the same. Specifically, r1 < r2. When changing from transporting the first workpiece 31 to transporting the second workpiece 32, the power unit 13 and the adjusting unit 14 drive the baffle 121 to move away from the receiving seat 122. In this solution, through the three points of contact of the workpiece with the first contact surface, the second contact surface, and the stop surface, it is ensured that the workpiece can be stably loaded on the receiving seat 122 and the baffle 121. And the contact points of the first workpiece 31 and the second workpiece 32 with the first contact surface, the second contact surface, and the stop surface are not the same, so as to be compatible with workpieces of different sizes.

[0055] In some embodiments of the present application, reference Figure 3 、 4 It should be noted that there is an unclear expression "传动连接" in the translation of item , which may need to be further determined according to the specific context. You can provide more accurate information for a more precise translation.As shown, the adjustment unit 14 includes a screw rod 141 and a threaded seat 143. The threaded seat 143 is threadedly connected to the screw rod 141. The threaded seat 143 is fixedly mounted on the baffle 121. The power unit 13 drives the screw rod 141 to rotate, thereby driving the threaded seat 143 and the baffle 121 to move along the axial direction of the screw rod 141.

[0056] Meanwhile, the power unit 13 includes a rotating shaft 131, and an adjusting hand wheel 133 is installed on one end of the rotating shaft 131. Moving wheels are installed on the rotating shaft 131 and the screw rod 141, and the rotating shaft 131 and the moving wheels of the screw rod 141 are connected by a synchronous belt 16. A shaft seat 112 is also installed on the side plate 11, and the rotating shaft 131 is rotatably connected to the shaft seat 112, so that the rotating shaft 131 rotates relative to the side plate 11. Although not shown in the figure, it can be understood that the screw rod 141 can also rotate relative to the side plate 11, and therefore, a shaft seat 112 is installed on the side plate 11, and the screw rod 141 is rotatably connected to the shaft seat 112.

[0057] Specifically, the conveyor belt is installed on one side of the side plate 11 close to the receiving seat 122, and the power unit 13 and the adjustment unit 14 are installed on the other side of the receiving seat 122. A through slide groove is provided on the surface of the side plate 11, and the threaded seat 143 passes through the slide groove, and the threaded seat 143 can slide along the slide groove.

[0058] Further, at least two adjustment units 14 are installed on the same side plate 11, and two screw rods 141 are respectively arranged above and below the rotating shaft 131. The rotating shaft 131 is installed with driving wheels 132 that are the same in number as the adjustment units 14, and the driving wheels 132 on the rotating shaft 131 are connected to the driven wheels 142 on the screw rod 141 in a one-to-one correspondence through a synchronous belt 16. Exemplarily, the number of adjustment units 14 installed on the same side plate 11 is two. Two driving wheels 132 are sequentially distributed on the rotating shaft 131, and the two driving wheels 132 are connected to the driven wheels 142 on the screw rod 141 in a one-to-one correspondence through two synchronous belts 16.

[0059] Furthermore, the base 17 is used to be arranged on the bottom surface, and the base 17 is connected to the side plate 11 and the baffle 121. In this solution, the base 17 and the stop surface of the baffle 121 are arranged at an acute angle, that is, the receiving seat 122 transmits the workpiece along a straight line direction inclined relative to the base 17, and the baffle 121 is arranged close to the side of the acute angle formed by the plane through which the receiving seat 122 passes and the base 17. It is ensured that the workpiece is pressed on the receiving seat 122 and the baffle 121, and the stability of the workpiece during the transmission process is improved.

[0060] In some embodiments of the present application, Figure 1 As shown, the loading assembly further includes a guide unit 15 , which is disposed close to the base 17 .

[0061] The guide unit 15 includes a guide plate 151 and a telescopic rod 152. The guide plate 151 is pivotally connected to the side plate 11 of the feeding assembly, and the telescopic rod 152 is connected to the base 17 and the bottom surface of the guide plate 151. By controlling the length of the telescopic rod 152, the angle formed by the guide plate 151 and the transmission direction of the conveyor belt can be adjusted to facilitate the guide plate 151 to align with the transfer device of workpieces of different specifications. The transfer device is specifically a functional structure located at the upstream end of the automatic feeding structure. Since the automatic feeding structure in this solution is used for transfer, the transfer device located at the upstream end of the automatic feeding structure can be other common functional structures in transfer equipment such as a color station structure, a material separation structure, and a stacking structure.

[0062] Furthermore, the push assembly includes a mounting seat 21, which is connected to the top plate 18, and the drive unit 22 is mounted on the mounting seat 21, so that the push rod 23 is close to the downstream end of the conveyor belt. In this solution, the cross-sectional area of ​​the push rod 23 gradually decreases toward the conveyor belt, so that the end of the push rod 23 that pushes the workpiece is pointed, and the contact area between the push rod 23 and the workpiece is reduced, thereby reducing the risk of collision between the push rod 23 and the workpiece.

[0063] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific implementations. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be understood to be within the scope of protection of the present application.
