Description

Technical Field

[0001] This utility model relates to the field of marking equipment technology, and more specifically to a fully automatic marking equipment for cutting tools. Background Technology

[0002] With the continuous improvement of automation in manufacturing, the requirements for marking information on precision parts such as cutting tools during production are becoming increasingly stringent. Traditional tool marking methods mainly rely on manual operation, typically involving operators manually placing the tool into a fixture and starting the marking equipment. This method has several problems: the entire marking process requires manual clamping, placement, and starting, resulting in high labor intensity, slow operation speed, and low efficiency; manual clamping and positioning are prone to introducing errors, leading to inconsistent marking positions.

[0003] Therefore, developing a fully automatic tool marking device with high marking efficiency and high marking position consistency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a fully automatic knife marking device with high marking efficiency and high marking position consistency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully automatic marking device for cutting tools, comprising:

[0007] The material tray includes an upper material tray and an lower material tray;

[0008] A turntable, the top of which is provided with an engraving position and a central rotation position;

[0009] A laser marking machine, wherein the laser emitting end of the laser marking machine corresponds to the marking position, and marks the tool at the marking position;

[0010] The robotic arm has grippers at its clamping end for gripping cutting tools.

[0011] The beneficial effects of adopting the above technical solution are that the entire process of tool loading, positioning, marking and unloading is automated through material trays, turntables, laser marking machines and robotic arms, which significantly reduces manual intervention, improves marking efficiency and ensures the consistency of marking position.

[0012] Preferably, the loading tray and unloading tray are arranged side by side on the top of the material platform; the top of the material platform is provided with a sliding groove, and the bottom of both the loading tray and the unloading tray is provided with a slider, which is placed in the sliding groove. The loading tray, unloading tray and material platform adopt a sliding groove-slider sliding engagement to realize the rapid insertion and removal and precise positioning of the material trays.

[0013] Preferably, a locking mechanism is provided on the side of the material platform. The locking mechanism includes a locking plate, a rotating shaft, a swing arm, and a locking cylinder. The rotating shaft is rotatably connected to the material platform. The locking plate is fixedly connected to the rotating shaft. One end of the swing arm is fixedly connected to the rotating shaft, and the other end is connected to the telescopic end of the locking cylinder. The locking cylinder is located at the bottom of the material platform. The telescopic movement of the locking cylinder sequentially drives the swing arm, the rotating shaft, and the locking plate to rotate, and the locking plate presses against the upper and lower material trays. The locking mechanism utilizes the linkage of the locking cylinder, swing arm, rotating shaft, and locking plate to synchronously press or release all material trays at once, preventing material tray displacement during marking and improving overall stability and safety.

[0014] Preferably, the gripper includes a picking gripper and a dispensing gripper; both the picking gripper and the dispensing gripper are disposed at the gripping end of the robot arm. The simultaneous configuration of the picking gripper and the dispensing gripper at the end of the robot arm enables parallel "picking and dispensing" actions, reducing the robot arm's idle travel and increasing output per unit time.

[0015] Preferably, a turntable motor is provided at the bottom of the turntable, the turntable motor is connected to the turntable, and drives the turntable to rotate. The turntable motor is a servo motor, and the turntable's marking position and intermediate rotation position are switched by forward and reverse rotation.

[0016] Preferably, the engraving position and the transfer position are located on the same diameter of the turntable, and the turntable is rotated 180° to achieve the swapping of the engraving position and the transfer position.

[0017] Preferably, the robotic arm is connected to a linear drive mechanism, which drives the robotic arm to move along the X-axis, Y-axis, and Z-axis.

[0018] Preferably, the marking equipment also includes an operating table, on which the material tray, turntable, laser marking machine, robotic arm and linear drive mechanism are all mounted.

[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a fully automatic marking device for cutting tools, the beneficial effects of which are:

[0020] (1) In this utility model, the marking is performed at the marking position, which ensures accurate positioning and consistent marking accuracy. At the same time, the intermediate position is set up to ensure that the printing tool is ready at the intermediate position during marking, so that the tool can mark continuously, which can effectively improve the marking efficiency.

[0021] (2) The marking equipment in this utility model reduces manual operation and greatly reduces labor intensity and manpower requirements. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] This utility model embodiment discloses a fully automatic marking device for cutting tools, including:

[0047] Material tray 1, which includes: upper material tray 11 and lower material tray 12;

[0048] Turntable 2, with an engraving position 21 and a central rotation position 22 on its top;

[0049] Laser marking machine 3, the laser emitting end of laser marking machine 3 corresponds to the marking position 21, and marks the tool 4 at the marking position 21;

[0050] Robotic arm 5, the clamping end of robotic arm 5 is equipped with grippers for gripping the cutting tool.

[0051] To further optimize the above technical solution, the loading tray 11 and the unloading tray 12 are arranged side by side on the top of the material platform 6; a sliding groove 61 is provided on the top of the material platform 6, and a slider 13 is provided at the bottom of both the loading tray 11 and the unloading tray 12, with the slider 13 placed in the sliding groove 61. There are three loading trays 11 and three unloading trays 12, arranged side by side on the top of the material platform 6.

[0052] To further optimize the above technical solution, the end of the slide 61 near the locking plate 71 is open and the end away from the locking plate 71 is closed, so that the locking plate 1 can be used to press the material tray 1.

[0053] To further optimize the above technical solution, a locking mechanism 7 is provided on the side of the material platform 6. The locking mechanism 7 includes a locking plate 71, a rotating shaft 72, a swing rod 73, and a locking cylinder 74. The rotating shaft 72 is rotatably connected to the material platform 6. The locking plate 71 is fixedly connected to the rotating shaft 72. One end of the swing rod 73 is fixedly connected to the rotating shaft 72, and the other end is connected to the telescopic end of the locking cylinder 74. The locking cylinder 74 is located at the bottom of the material platform 6. The telescopic movement of the locking cylinder 74 sequentially drives the swing rod 7372, the rotating shaft, and the locking plate 71 to rotate. The locking plate 71 presses against the upper material plate 11 and the lower material plate 12. The extension and retraction of the locking cylinder 74 can drive the swing rod 73 to rotate. The rotation of the swing rod 73 will drive the rotating shaft 72 to rotate, which in turn will drive the locking plate 71 to rotate. The rotation of the locking plate 71 will press the loading plate 11 or the unloading plate 12 tightly. There are multiple locking plates 71, and the positions of the locking plates 71 correspond one-to-one with the loading plate 11 and the unloading plate 12, which can ensure that each loading plate 11 and the unloading plate 12 is securely locked.

[0054] To further optimize the above technical solution, the gripper includes a material-grabbing gripper 51 and a material-releasing gripper 52; both the material-grabbing gripper 51 and the material-releasing gripper 52 are located at the gripping end of the robotic arm 5. The division of labor between the material-grabbing gripper 51 and the material-releasing gripper 52 can improve work efficiency.

[0055] To further optimize the above technical solution, a turntable motor is installed at the bottom of the turntable 2. The turntable motor is connected to the turntable 2 and drives the turntable 2 to rotate.

[0056] To further optimize the above technical solution, the engraving position 21 and the intermediate transfer position 22 are located on the same diameter of the turntable 2, and the turntable 2 is rotated 180° to realize the swapping of the engraving position 21 and the intermediate transfer position 22. Two positions for placing the cutting tool 4 are set up: the engraving position 21 and the intermediate transfer position 22. When the cutting tool 4 at the engraving position 21 is engraving, the robot arm 5 places the cutting tool 4 on the intermediate transfer position 22. After engraving is completed, the turntable motor drives the turntable 2 to rotate 180°, transferring the engraved cutting tool 4 to the intermediate transfer position 22. The robot arm 5 then picks up the material and places it into the unloading tray 12. At the same time, after the robot arm 5 has placed the material, it will pick up the material again and place it on the intermediate transfer position 22. The unengraved cutting tool 4 is transferred to the engraving position 21 for engraving. After engraving is completed, the turntable motor drives the turntable 2 to rotate 180° in the opposite direction, transferring the engraved cutting tool 4 to the intermediate transfer position 22. The reciprocating alternation between the engraving position 21 and the intermediate transfer position 22 can ensure the continuity of the engraving operation and effectively improve the engraving efficiency.

[0057] To further optimize the above technical solution, clamps are provided at the engraving position 21 and the intermediate rotation position 22 of the turntable 2 to position the tool 4.

[0058] To further optimize the above technical solution, the robotic arm 5 is connected to a linear drive mechanism 8, which drives the robotic arm 5 to move along the X, Y, and Z axes. The linear drive mechanism 8 is a linear module that uses a motor to drive a slider to move on a slide rail, thereby realizing the movement of the robotic arm 5 in the three directions of the X, Y, and Z axes.

[0059] To further optimize the above technical solution, the marking equipment also includes an operating table 9, a material tray 1, a turntable 2, a laser marking machine 3, a robotic arm 6, and a linear drive mechanism 8, all of which are mounted on the operating table 9.

[0060] Work process:

[0061] The staff places a batch of four cutting tools to be marked into the loading tray 11, and pushes the loading tray 11 and unloading tray 12 into place along the slide groove 61 of the material table 6; the locking cylinder 74 extends, and drives the locking plate 71 to rotate through the swing rod 73 and the rotating shaft 72, firmly fixing the loading tray 11; the linear drive mechanism 8 drives the robot arm 5 to move above the loading tray 11, and the picking gripper 51 picks up the first cutting tool 4; the robot arm 5 continues to move, accurately placing the cutting tool 4 at the clamping position 22 of the turntable 2, and the clamping position 22 immediately clamps the cutting tool 4; the turntable motor starts, the turntable 2 rotates 180°, the clamping position 22 and the clamping position 21 exchange positions, and the cutting tool 4 then enters the laser marking position. The laser marking machine 3 marks the tool 4 on the marking position 21. After completion, the turntable motor rotates 180° in the opposite direction again, and the marked tool 4 is sent back to the transfer position 22. The unloading gripper 52 of the robot arm 5 picks up the marked tool 4 on the transfer position 22, moves it and releases it to the adjacent unloading tray 12. Then the picking gripper 51 puts the new tool 4 to be marked into the transfer position 22. Repeat the above steps to realize the continuous cycle of "loading-transfer-marking-reset-unloading-loading" until all the tools in the loading tray 11 are marked. The operator pulls out the full unloading tray 12 and replaces it with an empty tray. The equipment can continue the next round of operation without stopping.
