Description

Technical Field

[0001] This utility model relates to the field of material tray device technology, and in particular to an improved material tray device. Background Technology

[0002] A tray device is a commonly used part transfer and placement device in a workshop, used for temporary storage of parts during the transfer process.

[0003] Traditional aluminum shell material trays are often stackable material trays, which have multiple storage structures on the material tray, allowing multiple target workpieces to be temporarily stored in a stacked manner. During use, a whole row of workpieces can be manually taken out at the same time, stored neatly and orderly, which is convenient for batch loading in the next process.

[0004] However, current technologies often use multi-axis robots for workpiece transfer to eliminate manual handling and transfer. Traditional tray structures lack a pushing mechanism, and the grippers at the end of the robot arm have difficulty picking up parts one by one, resulting in low automation adaptability. Therefore, it is necessary to improve them. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an improved material tray device that can intermittently lift the workpieces in each row to cooperate with the robot arm to load and position each workpiece one by one, thereby improving the automation adaptability of the material tray device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an improved material tray device, including a base frame, a material tray, and a lifting mechanism. The material tray is rotatably mounted on the base frame and is driven by an intermittent drive device to achieve intermittent rotational engagement at equal intervals. The periphery of the material tray is provided with multiple stacking sections, each stacking section being spaced apart along the circumferential direction. Each stacking section is provided with a stacking positioning structure, which has a stacking space extending vertically for stacking and placing workpieces. A tray movably mounted vertically is installed inside the stacking space. The periphery of the material tray is also provided with multiple clearance notches, each clearance notch being located at the bottom of the corresponding stacking space. The lifting mechanism includes a lifting bracket and a lifting plate. The lifting bracket is fixedly mounted on one side of the base frame and is provided with a vertical guide rod. The lifting plate is slidably mounted on the guide rod and is driven by a lifting drive device. The lifting plate passes through the corresponding clearance notches and contacts the bottom of the corresponding trays to lift and deliver the workpieces arranged in rows in the corresponding stacking positioning structures one by one.

[0007] In a further technical solution, the stacking positioning structure includes multiple limiting rods, each of which is spaced apart along the edge trajectory of the target workpiece to form a stacking space that matches the target workpiece. Each limiting rod acts on the workpiece placed in the stacking space to limit its movement.

[0008] In a further technical solution, the projected shape of the lifting plate matches the distribution trajectory shape of each limiting rod in the corresponding stacked positioning structure. The edge of the lifting plate is provided with multiple sliding connection parts that match the limiting rods. The sliding connection parts include sleeve holes and / or notches. The lifting plate is slidably connected to each limiting rod in the corresponding stacked positioning structure through the sliding connection parts.

[0009] In a further technical solution, in the same stacked positioning structure, the clearance notch is located at the middle position of the bottom of the corresponding stacked space, and the corresponding limiting rods are symmetrically distributed on both sides of the clearance notch.

[0010] In a further technical solution, the front end of the lifting plate is formed with a lifting abutment that matches the clearance notch. The upper surface of the lifting abutment is flat and fits tightly against the bottom surface of the corresponding tray.

[0011] In a further technical solution, the intermittent drive device includes a cam divider, a reducer, and a drive motor, which are respectively fixedly installed on the base frame. The cam divider, reducer, and drive motor are connected in sequence. The cam divider is located at the center of the base frame, and a shaft connection is provided at the top of the cam divider. A shaft is provided at the center of the bottom surface of the material tray, and the shaft is inserted into the shaft connection of the cam divider to realize the intermittent rotation of the material tray at equal intervals.

[0012] In a further technical solution, six stacked positioning structures are set, and these six stacked positioning structures are distributed at equal intervals on the edge of the tray.

[0013] In a further technical solution, the lifting support includes a top plate, a vertical plate, and a bottom plate. The bottom plate is fixedly installed on the base frame. The vertical plate is vertically arranged, with its bottom end fixed to the bottom plate. The top plate is horizontally arranged, with one side of the top plate fixed to the top of the vertical plate. The top plate is located directly above the bottom plate, and the two are arranged parallel to each other. The upper and lower ends of the guide rod are fixed to the top plate and the bottom plate, respectively. The lifting drive device includes a drive screw, with the upper and lower ends of the drive screw rotatably connected to the top plate and the bottom plate, respectively. The drive screw is parallel to the guide rod. The lifting plate is equipped with a screw pair and a linear bearing. The screw pair is threadedly connected to the drive screw, and the linear bearing is slidably sleeved on the guide rod.

[0014] In a further technical solution, a motor base is provided at the bottom of the base plate, and a servo reducer and a servo motor are provided on the motor base. The servo reducer is fixed to the motor base, and the servo motor is connected to the input end of the servo reducer. The servo reducer has an output shaft, and the output shaft of the servo reducer is provided with a drive pulley. The bottom end of the drive screw is provided with a driven pulley, and a synchronous belt is wound between the drive pulley and the driven pulley.

The wireless limit switches, servo motor and intermittent drive device are electrically connected to the control circuit respectively.

[0016] The advantages of this invention compared to the prior art after adopting the above structure are: 1. By using a material tray that rotates intermittently at equal angles in conjunction with a lifting mechanism, workpieces placed in a stacked positioning structure and arranged in rows are lifted and sent out one by one, so that each workpiece on the material tray can be discharged at the same height and posture. This is combined with the loading and positioning of the robotic arm fixture to improve the automation adaptability of the material tray device and optimize the human-machine interaction in the semi-automatic production line.

[0017] 2. The cam divider drives the material tray to rotate intermittently at equal intervals, so that each row of workpieces can be accurately lifted and discharged by the lifting mechanism in sequence. The structure is simple and the operation is stable and reliable.

[0018] 3. The tray, which is slidably connected to the limit rod, supports and lifts the rows of workpieces one by one for output, preventing the workpieces from collapsing and ensuring that the output posture of each workpiece remains horizontal. This ensures the stability of the loading and positioning coordination with the robot arm fixture and further improves the reliability of the equipment.

[0019] 4. The lifting plate is driven by a servo motor to push the material upward. By utilizing the output characteristics of the servo motor, the stacked workpieces can be discharged with high precision intermittent lifting. This ensures that the top workpiece is at the same height when it is positioned and loaded by the robotic arm, further improving the reliability of the automated adaptation of the material tray device.
