Description

Technical Field

[0001] This utility model relates to the technical field of workpiece conveying, specifically to a track docking mechanism for rotating two workpieces by 90 degrees. Background Technology

[0002] In modern industrial production, workpieces assembled in the previous stage need to be rotated 90° vertically before being fed into the subsequent conveyor line. Currently, multi-axis robots are commonly used for workpiece transfer. However, in practice, when two workpieces need to be transferred at once, the multi-axis robot requires two sets of spaced grippers, and precise control of their rotation and movement is crucial. This significantly increases equipment costs. Furthermore, the repeated forward and backward movements of the multi-axis robot hinder product transfer efficiency. Therefore, there is an urgent need to develop a mechanism capable of reliably transferring two workpieces after a 90-degree rotation, thereby improving transfer efficiency and reducing equipment costs. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a track docking mechanism that allows for the rotation of two workpieces by 90 degrees, which improves product transfer efficiency and reduces the cost of transfer equipment.

[0005] The first material rail includes a dual workpiece loading station and a dual workpiece buffer station, and the first material rail is provided with a linearly arranged first track groove.

[0006] The second material channel includes a second track groove, the width of which is adapted to the width of a workpiece that has been rotated 90°, and the conveyor belt of the second material channel is used to transport the workpiece.

[0007] A shift fork mechanism includes a shift fork lever and a shift fork body. The shift fork body is provided with a first double workpiece notch assembly and a second double workpiece notch assembly. The two notches of the double workpiece notch assembly are arranged to align with the corresponding positions of two workpieces.

[0008] A shift fork drive assembly drives the shift fork mechanism to move parallel to the first material rail and drives the shift fork mechanism to move away from or towards the first track groove.

[0009] Workpiece pushing cylinder;

[0010] And a flipping assembly, which includes a flipping carrier and a flipping drive mechanism, wherein the flipping drive mechanism drives the flipping carrier to flip 90 degrees vertically and return to its original position 90 degrees.

[0011] A flipping component is provided at the inlet position of the second material channel. After the flipping carrier of the flipping component drives the two workpieces to flip 90 degrees, they are positioned at the inlet of the second material channel. The piston end of the workpiece pushing cylinder pushes the two workpieces toward the second track groove of the second material channel. A flipping component is provided at the outlet position of the first material track. In the initial state when the flipping carrier of the flipping component is not flipped, it is positioned at the outlet of the first material track.

[0012] Its further features are:

[0013] The workpiece is a workpiece with an open top. The flipping carrier includes a carrier cavity and a carrier flipping end. The carrier cavity is provided with a protruding positioning corresponding to the open top of the workpiece, which ensures that the workpiece will not fall out of the carrier cavity during the vertical flipping process.

[0014] The vehicle's flipping end is provided with a keyway input hole, and the rotation output shaft of the flipping drive mechanism is connected to the keyway input hole through a key structure to ensure that the flipping is stable and reliable.

[0015] The flipping drive mechanism includes front and rear drive cylinders, a linear rack, a gear, a rotary output shaft, and a mounting base. The output ends of the front and rear drive cylinders are connected to the linear rack, the linear rack meshes with the gear located above it, the gear and the rotary output shaft are fixedly connected, and the rotary output shaft is inserted into the keyway input hole of the flipping end of the carrier and supported at both ends by the positioning holes of the mounting base.

[0017] The shift fork drive assembly includes left and right rodless cylinders and front and rear slide rail cylinders. The output ends of the left and right rodless cylinders are fixedly mounted with the front and rear slide rail cylinders, and the output ends of the front and rear slide rail cylinders are fixedly connected to the shift fork rod. The left and right rodless cylinders drive the two workpieces located at the double workpiece loading station to move to the double workpiece buffer station, and at the same time drive the two workpieces located at the double workpiece buffer station to move into the carrier cavity in the initial state of the flipping carrier before it is flipped. The front and rear slide rail cylinders drive the shift fork mechanism to move away from or towards the first track groove, thereby completing the set action.

[0018] The front end of the second feed channel is also provided with a guide block, which is installed on the front end of the second track groove to ensure that the workpiece is reliably pushed.

[0019] After adopting this utility model, the previous process transports the workpiece to be processed to the corresponding position of the first track groove of the double workpiece loading station of the first material rail. The shift fork drive assembly drives the shift fork mechanism to move parallel along the first material rail and move the two workpieces of the double workpiece loading station to the double workpiece buffer station, and finally move them into the carrier cavity in the initial state of the flipping carrier before it is flipped. Then, the flipping carrier is flipped 90 degrees under the drive of the flipping drive mechanism. After the flipping carrier of the flipping assembly drives the two workpieces to flip 90 degrees, they are aligned with the inlet of the second material channel. The piston end of the push workpiece cylinder pushes the two workpieces into the second track groove of the second material channel. Then, the conveyor belt of the second material channel transports the two workpieces to the rear. Then, the push workpiece cylinder resets and the flipping carrier resets. The above process is repeated to realize continuous double workpiece flipping and docking transportation, which improves the product transfer efficiency and reduces the cost of transfer equipment.
