Description

Technical Field

[0001] The utility model relates to the technical field of material turning devices, in particular to a material turning mechanism. Background Art

[0002] During the machining process, workpieces often need to be flipped over for the next step. For example, a rectangular, long workpiece removed from a forming machine may have three concave sides and only one flat side. This flat side must face downward during subsequent sintering to prevent deformation. The conventional method involves manually flipping workpieces one by one, which requires a significant amount of manpower, is inefficient, and results in high processing costs. Furthermore, manual operation can easily lead to omissions, negatively impacting subsequent processing.

[0003] Chinese invention patent application publication number CN 109648381 A discloses an automatic material turning mechanism. The mechanism comprises a base on which a turning plate, driven by a rotary power unit, is rotatably mounted. The turning plate defines a receiving slot for receiving the product, and two material retaining devices are positioned on the top and bottom surfaces of the turning plate, surrounding each slot. This mechanism requires a robot to first load the workpiece into the slot before turning the material. While this saves manpower, the need to place the product into the slot requires high precision and results in low production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Based on these descriptions, a person skilled in the art will be able to implement the present invention. Furthermore, the embodiments of the present invention described below generally represent only a portion of the present invention, rather than all of the embodiments. Therefore, all other embodiments derived by a person skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0022] A turning mechanism is used to turn the workpiece 5 over to facilitate the next process. Figure 1 As shown, the turning mechanism includes a conveyor belt 1 for placing and conveying workpieces 5, and a stepper motor 3 is provided on one side of the conveyor belt 1 to provide power for the operation of the conveyor belt 1. At the same time, in order to place the workpiece 5 stably, the conveyor belt 1 is arranged horizontally.

[0023] A second mounting base 44 is mounted on the frame of the conveyor belt 1. A vertical rod 43 is positioned above the second mounting base 44. A positioning block 42 is located at the upper end of the vertical rod 43. A suspension rod 41 is mounted on the positioning block 42 and is positioned parallel to the conveyor belt 1. A sensing device 4 is mounted on the suspension rod 41 to detect whether a workpiece 5 on the conveyor belt 1 is within a target area. The sensing device 4 can slide on the suspension rod 41 and rotate relative to the suspension rod 41 to facilitate adjustment of its sensing area.

[0024] The stepper motor 3, conveyor belt 1, and sensor 4 cooperate to facilitate the flipping of the workpiece 5 by the flipping mechanism. Specifically, when the workpiece 5 is placed on the running conveyor belt 1, the sensor 4 senses the workpiece 5, and the conveyor belt 1 stops. In this embodiment, the sensor 4 is a color mark sensor. The robot places the workpiece 5 on the conveyor belt 1 at a specific angle. The color block on the workpiece 5 is detected by the color mark sensor, and the conveyor belt 1 stops. The flipping component in the flipping mechanism flips the workpiece 5. After the flip, the workpiece 5 is no longer recognized by the color mark sensor, and the conveyor belt 1 resumes operation, transporting the workpiece 5 to the next process step.

[0025] The turning mechanism also includes a turning assembly for turning over the workpiece 5 placed on the conveyor belt 1. The turning assembly is arranged on the other side of the conveyor belt 1, that is, the turning assembly and the sensing device 4 are respectively located on both sides of the conveyor belt 1. The turning assembly includes an adjusting member 21, a lifting member 22, and a driving member 23. The adjusting member 21 and the lifting member 22 are arranged above the conveyor belt 1. The lifting member 22 controls the raising and lowering of the adjusting member 21 so that it can contact the workpiece 5. The adjusting member 21 turns the workpiece 5 through static friction. The driving member 23 drives the adjusting member 21 to move in the conveying direction of the workpiece 5, thereby causing the workpiece 5 to turn 90 degrees.

[0026] In order to prevent the adjusting member 21 from damaging the workpiece 5 when in contact with the workpiece 5, a flexible material layer is provided on the lower end surface of the adjusting member 21. In this embodiment, the flexible material layer is foam.

[0027] In addition, in order to ensure that the sensing device 4 can promptly identify the product after the adjusting member 21 completes flipping the product, the sensing area of ​​the sensing device 4 corresponds to the working area of ​​the adjusting member 21 .

[0028] The driving member 23 includes a track 231, a screw rod 232, and a motor 233. The track 231 and screw rod 232 are arranged in parallel and parallel to the conveyor belt 1. The motor 233 is disposed at one end of the screw rod 232 and is used to drive the screw rod 232 to rotate. Furthermore, a first mounting seat 221 is provided on the track 231 and screw rod 232, and the lifting member 22 is connected to the track 231 and screw rod 232 via the first mounting seat 221. Therefore, starting the motor 233 can drive the lifting member 22 to move horizontally, thereby driving the adjustment member 21 connected to the lifting member 22 to move in the same manner. In this embodiment, the motor 233 of the driving member 23 is a servo motor.

[0029] In this embodiment, the lifting member 22 is the fixed end of the cylinder, which is connected to the track 231 and the screw rod 232 through the first mounting base 221. The adjusting member 21 is the moving end of the cylinder. The cylinder is vertically arranged with the moving end arranged below the fixed end and can move in the vertical direction.

[0030] Workpiece 5 is placed on conveyor belt 1, which stops. The cylinder's moving end extends downward until it presses against workpiece 5. Screw rod 232 and the servo motor drive the cylinder's fixed end to move horizontally along track 231, causing static friction to cause the workpiece 5 beneath the cylinder's moving end to flip 90 degrees. Furthermore, foam is placed on the lower end of the cylinder's moving end to prevent damage to the workpiece 5 when pressed against it.

[0031] The method of using the turning mechanism disclosed in this embodiment is as follows:

[0032] Workpiece 5 is placed on conveyor belt 1 by the robot. The color mark sensor senses workpiece 5, and conveyor belt 1 stops. The moving end of the cylinder moves downward, pressing against workpiece 5. The servo motor and screw 232 then drive the fixed end of the cylinder to move horizontally, causing workpiece 5 to flip 90 degrees. After flipping, workpiece 5 is no longer sensed by the color mark sensor. Stepper motor 3 and conveyor belt 1 resume operation, transporting workpiece 5 to the designated location. Using a flipping mechanism instead of manual flipping avoids wasted human resources, saves production time, and improves production efficiency.
