Description

Technical Field

[0001] The present invention belongs to the field of mechanical technology, and relates to a laser-engraved QR code device, in particular to a full-automatic laser engraver, a laser engraving method and a processing assembly line. Background Art

[0002] In the production of electronic products, laser engraving technology is often used to mark information on electronic products, and the products are inspected after laser engraving. At present, the loading and unloading of laser engraving equipment usually uses a manipulator to clamp, or multiple sets of transverse movement modules cooperate to grab the products and then place them on the laser engraving fixture, resulting in an increase in equipment costs. In the prior art, the time for laser engraving a single electronic product is twice the time for inspecting a single electronic product, resulting in an extended operation time for the process.

[0003] For example, the Chinese patent literature has disclosed an automatic laser engraver [Chinese Patent No.: CN202021559139.7]. The present utility model discloses an automatic laser engraver, which includes a base, a first laser engraving turntable mechanism, a second laser engraving turntable mechanism, a first laser engraver, a second laser engraver and a workpiece translation device. Laser engraving fixtures are provided on the first laser engraving turntable mechanism and the second laser engraving turntable mechanism, and each laser engraving fixture is provided with adjacent first workpiece positioning parts and second workpiece positioning parts. The workpiece translation device transfers the workpiece in the laser engraving fixture on the first laser engraving turntable mechanism to the laser engraving fixture on the second laser engraving turntable mechanism. The advantage of this setting is that in the process of laser engraving, two workpieces can be loaded at the same time, and two workpieces can be produced at the same time after laser engraving, so that the production capacity of the laser engraving process is the same as that of the inspection process.

[0004] In the above technical solution, multiple transfer devices are used to transfer products between processes, resulting in a complex overall equipment layout. The product flow path is long and a multi-directional turning path, which not only increases the equipment cost and the product sales price, but also leads to a lack of fluency in the process flow, and thus easily causes problems such as deviations during product transfer. In addition, due to the long flow path, the transfer time between processes is extended. In addition, in the above technical solution, the product is transferred by the planar rotation of the turntable, so that the product makes a planar circular displacement, resulting in a change in the turning angle. And the difficulty of accurately positioning the planar angle is relatively high, resulting in low product positioning accuracy, large product processing errors and an increase in the defective rate.

Specific embodiments

[0042] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0043] Embodiment 1

A laser welding head 27 is erected above the transfer and positioning mechanism; the transfer and positioning mechanism includes a vertically arranged transfer disk 8. A plurality of material-inserting ports are evenly arranged along the circumference of the transfer disk 8. The material-inserting ports are rotationally aligned with the pushing component / pulling component. An assembly rack 12 is erected on the outer periphery of the transfer disk 8. Clamping components are arranged on both sides of the assembly rack 12, and a positioning component is arranged on the top side of the assembly rack 12.

[0045] The conveying and feeding mechanism includes a crosswise feeding electric cylinder 2. The crosswise feeding electric cylinder 2 is drivingly connected to a feeding lifter 3. A feeding gripper 4 is connected to the lifting end of the feeding lifter 3. A feeding table 5 is connected between the crosswise feeding electric cylinder 2 and the transfer disk 8. The feeding gripper 4 reciprocates above the feeding table 5. The crosswise feeding electric cylinder 2 drives the feeding lifter 3 to reciprocate horizontally by means of sliding drive. The feeding lifter 3 is specifically any one of a cylinder, a hydraulic cylinder, an electric cylinder, and an electric push rod. The feeding gripper 4 is driven by the feeding lifter 3 to realize height lifting. A plurality of suction cups are arranged on the bottom surface of the feeding gripper 4, and products are adsorbed by vacuum pumping.

[0046] The pushing component includes a pusher 6. A pushing block 7 is fixedly connected to the telescopic shaft of the pusher 6. An introduction notch is opened on the side wall of the feeding table 5. The pushing block 7 enters and exits the loading cavity of the feeding table 5 through the introduction notch. The pusher 6 is specifically any one of a cylinder, a hydraulic cylinder, an electric cylinder, and an electric push rod. By extending the telescopic shaft of the pusher 6, the pushing block 7 is driven to push the product in the feeding table 5 into the transfer disk 8. The crosswise feeding electric cylinder 2 is fixedly installed on the feeding rack, and the pusher 6 is fixedly installed below the feeding rack, thereby saving the assembly space. At the same time, the structural layout is reasonable, which is convenient for connecting the pushing action after the feeding action and improving the feeding efficiency.

[0047] The center of the transfer disk 8 is fixedly penetrated by a rotating shaft 9. The rotating shaft 9 passes through the assembly frame 12 to form a rotational connection. A support is erected on the workbench, and a rotating motor 11 is fixedly installed on the support. The rotating motor 11 is in transmission connection with the rotating shaft 9 through a coupling 10. The rotating motor 11 provides the rotational driving force for the transfer disk 8, and at the same time controls the stop and positioning rules of the transfer disk 8. The rotational transmission is carried out through the coupling 10, and at the same time, the rotational speed of the transfer disk 8 is adjusted.

[0048] The transfer disk 8 includes two disks arranged oppositely. The centers of the two disks are fixedly connected by an integral column.

The horn-shaped opening facilitates the import and export of products and avoids pinching or scratching the surface of the products.

[0049] The clamping component includes lifters 13 located on both sides of the assembly frame 12. The lifters 13 drive the lifting claws 15 to lift and lower. The lifting claws 15 have an L-shaped claw body, and the top surface of the cross bar of the L-shaped claw body has a downward-inclined slope. The bottom right-angle part of the product is correspondingly supported by the L-shaped claw body, and the contact area with the bottom edge of the product is reduced through the downward-inclined slope, so that both the supporting effect can be realized and the product can be prevented from being scratched. The lifter 13 is specifically any one of a cylinder, a hydraulic cylinder, an electric cylinder, and an electric push rod. The two side lifters 13 simultaneously lift the lifting claws 15 to realize the jacking effect on the product.

[0050] In this embodiment, the lifting end of the lifter 13 on one side is directly fixedly connected to the lifting claw 15, so a horizontal fixed point is formed on this side; the lifting end of the lifter 13 on the other side is fixedly connected to the gripper 14, and then the translation end of the gripper 14 is fixedly connected to the lifting claw 15, so a horizontal moving point is formed on this side. First, the gripper 14 moves the lifting claw 15 inward to cooperate with the lifting claw 15 at the fixed point to firmly clamp the product horizontally, and then the two side lifters 13 synchronously lift the product. The gripper 14 is specifically any one of a cylinder, a hydraulic cylinder, an electric cylinder, and an electric push rod.

[0051] The material positioning component includes lower presses 16 symmetrically and fixedly arranged at the top ends of both sides of the assembly frame 12. A positioning plate 17 is driven to lift and lower synchronously between the two lower presses 16. At least one rotating lower press cylinder 18 is penetrated through the positioning plate 17, and a clamping gap is formed between the rotating press head 19 of the rotating lower press cylinder 18 and the positioning plate 17. The lower press 16 is specifically any one of a slide table cylinder, a hydraulic cylinder, an electric cylinder, and an electric push rod. The lower press 16 drives the positioning plate 17 to descend to form a blocking for the product to turn and lean against, and the rotating press head 19 of the rotating lower press cylinder 18 is swung to the surface of the product, so that the top edge of the product is located in the clamping gap to form a fixation.

[0052] The conveying and material receiving mechanism includes a transverse material receiving electric cylinder 24. The transverse material receiving electric cylinder 24 is drivingly connected to a material receiving lifter 25. A material receiving gripper 26 is connected to the lifting end of the material receiving lifter 25. A blanking table 20 is connected between the transverse material receiving electric cylinder 24 and the transfer tray 8. The material receiving gripper 26 reciprocates above the blanking table 20. The transverse material receiving electric cylinder 24 drives the material receiving lifter 25 to reciprocate horizontally in a sliding drive manner. The material receiving lifter 25 is specifically any one of a cylinder, a hydraulic cylinder, an electric cylinder, and an electric push rod. The material receiving lifter 25 drives the material receiving gripper 26 to achieve height lifting. A plurality of suction cups are arranged on the bottom surface of the material receiving gripper 26, and the product is adsorbed by vacuum pumping.

[0053] The material pulling assembly includes a material puller 22 located below the blanking table 20. A pull bar 23 is fixedly connected to the telescopic shaft of the material puller 22. The end of the pull bar 23 is turned up to form a hook. The pull bar 23 extends into the transfer tray 8 so that the hook is located at the inner end of the material embedding port. The material puller 22 is specifically any one of a cylinder, a hydraulic cylinder, an electric cylinder, and an electric push rod. By extending the telescopic shaft of the material puller 22, the hook of the pull bar 23 reaches the inner end of the material embedding port. When the transfer tray 8 rotates downward and the product contacts the hook, the material puller 22 retracts the telescopic shaft and uses the hook of the pull bar 23 to hook out the product from the inner end of the material embedding port and translate it to the blanking table 20. The transverse material receiving electric cylinder 24 is fixedly installed on the material receiving frame, and the material puller 22 is fixedly installed below the material receiving frame, thus saving assembly space. At the same time, the structural layout is reasonable, which is convenient for connecting the material receiving action after the material pulling action and improving the blanking efficiency.

[0054] The blanking table 20 extends guide plates to both sides of the transfer tray 8. Guide rails 21 are arranged on the guide plates. The pull bar 23 extends out from the gap between the two guide plates. During the process of the pull bar 23 hooking out the product outward, the two side edges of the product are supported on the guide rails 21 and slide along them, thereby improving the stability of product blanking and avoiding deviation or falling off.

8. The full-automatic laser engraving machine according to claim 7, characterized in that the blanking table extends guiding plates towards both sides of the transfer disk. Guide rails are arranged on the guiding plates. The pull bar extends out from the gap between the two guiding plates on both sides.

9. A laser engraving method using the full-automatic laser engraving machine according to any one of claims 1-8, characterized in that it includes the following steps: 1), driving the loading jaw to descend through the loading lifter, adsorbing the product through the loading jaw, and translating the product through the transverse loading electric cylinder and placing it on the loading table; 2), driving the push block to push the product in the loading table into the corresponding and connected material-inserting opening on the transfer disk by extending the telescopic shaft of the pusher; 3), driving the transfer disk to rotate clockwise by 90° through the rotating motor so that the material-inserting opening carries the product and is set upwards; 4), driving the positioning plate to descend through the lower presser, so that the top edge of the product in the vertical state abuts against the positioning plate to form a positioning block; 5), first horizontally clamping the product firmly by the inward-translating lifting claw of the gripper cooperating with the fixed lifting claw on the other side, and then synchronously lifting the product by the lifters on both sides; 6), swinging the rotary pressure head to the other surface of the product through the rotary lower pressure cylinder, so that the top edge of the product is located in the clamping gap to form a fixation; 7), starting the laser welding head to perform two-dimensional code laser engraving on the top edge of the product; 8), the rotary lower pressure cylinder swings the rotary pressure head in the reverse direction to disengage from the product surface, and the lower presser drives the positioning plate to rise, so that the positioning plate is separated from the top edge of the product; 9), driving the transfer disk to continue rotating clockwise by 90° through the rotating motor so that the material-inserting opening carries the product and is set horizontally; 10), retracting the telescopic shaft of the puller through the puller and using the hook of the pull bar to hook out the product from the material-inserting opening, and translating it to the blanking table; 11), driving the receiving jaw to descend through the receiving lifter, adsorbing the product through the receiving jaw, and translating the product through the transverse receiving electric cylinder for recycling.

10. A processing assembly line, characterized in that it includes the full-automatic laser engraving machine according to any one of claims 1 to 8.
