[0002] Sheet metal is a smooth, flat metal semi-finished product rolled from a slab. Its length and width are much greater than its thickness. It is widely used in mechanical engineering, construction and other fields. Furniture sheet metal is one type of sheet metal. Furniture sheet metal refers to various board materials used to make furniture, mainly including wood-based panels and other material panels.

[0003] In the furniture board processing process, traditional feeding tables rely on manual visual inspection of the remaining amount of boards, which has problems of low efficiency and high misjudgment rate. Moreover, nowadays, most boards are stacked and then fed in conjunction with robotic arms and other components. It is difficult to know the remaining amount of boards in this process, which can easily lead to delays in replenishment response and affect the continuity of the production line.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal feeding device with a photoelectric distance sensing mechanism, comprising a support platform, a placement platform, and a conveyor belt. Limiting rods are fixed on both sides of the front and rear ends of the placement platform. A first set of rods is fixed at the upper end of the end face of the limiting rods. An electric push rod is installed inside the first set of rods. The telescopic end of the electric push rod is connected to one end of a second set of rods. A photoelectric sensor is installed at the other end of the second set of rods. A vertical rod is fixed on the top of the support platform at the left side of the placement platform. A first telescopic rod is installed on the side of the vertical rod. A pushing block is connected to the side of the first telescopic rod. The pushing block is located above the placement platform.

[0006] As a further technical solution of this utility model, the limiting rods are symmetrically distributed about the central axis of the placement platform, the placement platform and the limiting rods are welded and fixed together, and a gravity sensor is installed inside the top of the placement platform.

[0007] As a further technical solution of this utility model, a working motor is installed inside the support platform, the output end of the working motor is connected to a transmission disc, and an adjustment box is fixed to the top of the transmission disc.

[0008] As a further technical solution of this utility model, a servo motor is installed at the top of the adjustment box, a threaded rod is installed inside the adjustment box, a threaded block is connected to the outside of the threaded rod, and a first rod body is fixedly connected to the side of the threaded block by a guide block.

[0009] As a further technical solution of this utility model, a fourth telescopic rod is installed inside the first rod body, and a second rod body is connected to the side of the fourth telescopic rod body. A guide rail is fixed at the upper and lower positions inside the first rod body, and a slider is fixed at the upper and lower positions on the side of the second rod body.

[0010] As a further technical solution of this utility model, the guide rails are symmetrically distributed about the central axis of the first rod, the sliders are symmetrically distributed about the central axis of the second rod, and the guide rails pass through the interior of the sliders to form a sliding connection.

[0012] As a further technical solution of this utility model, a notch is formed in the clamping frame, and a third telescopic rod is installed at the front and rear positions of the inner wall of the notch, and a clamping plate is connected to the end face of the third telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the sheet material feeding device with photoelectric distance sensing mechanism not only improves the residual material detection capability, but also improves the sheet material clamping capability and pushing capability of the sheet material feeding device.

[0014] (1) By fixing the placement platform at the top of the support platform, the sheet metal can be stacked above the placement platform. The limiting rod is fixed at the front and rear of the placement platform to limit the sheet metal. The first set of rods is installed at the upper position of the end face of the limiting rod. During normal testing, the photoelectric sensor can be used to monitor the remaining amount. When the range of material replenishment is reached, the electric push rod in the first set of rods can be activated to retract the photoelectric sensor. Then, the clamping frame is used to clamp the sheet metal, and the working motor is activated to drive the transmission disk to rotate. First, the direction of the clamping frame is adjusted, and then the servo motor is activated to drive the threaded rod to rotate. The height position of the clamping frame is adjusted by the threaded block and the threaded rod. Finally, the clamping frame is used to replenish the sheet metal, thereby improving the continuity of the work.

[0015] (2) The connection between the second telescopic rod and the clamping frame is completed by using the connecting block. A notch is opened in the clamping frame. At this time, after the third telescopic rod works, the clamping plate can be pushed to move back and forth. Therefore, the distance between the two clamping plates can be adjusted, which facilitates the clamping of the plate by the two clamping plates. In this way, the clamping ability of the plate is improved in the working process.

[0016] (3) By fixing the vertical rod at the top of the support platform in the direction of the placement platform, the first telescopic rod is installed on the side of the vertical rod. Therefore, when pushing the material, the first telescopic rod can be activated to push the push block to move laterally. The push block pushes the plate material to the position of the conveyor belt for conveying. In this process, the vertical rod can be designed as a sleeve rod, which makes it convenient to adjust the height position of the vertical rod, thereby improving the overall pushing capacity in the working process.
