Description

Technical Field

[0001] The utility model relates to product processing equipment, in particular to laser engraving equipment for products. Background Art

[0002] Laser engraving, also known as laser engraving or laser marking, is a surface treatment process that uses optical principles. Laser engraving offers advantages such as fast marking speed, beautiful image quality, high resolution, durability, wide application range, safety and reliability, high accuracy, consistent results, high speed, low cost, and strong anti-counterfeiting capabilities. Currently, this process is widely used in cosmetic packaging (such as lipstick tubes and air cushions). Utility Model Content

[0003] The technical problem solved by the utility model is to provide a mechanical structure which can adapt to a variety of products and can perform laser engraving on multiple sides of the products.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a multi-product multi-surface laser engraving mechanism, comprising a conveyor line arranged on a working base plate, and a transfer mechanism arranged on the conveyor line. The working base plate is divided into a loading station and a laser engraving station according to the conveying direction of the conveyor line. A number of laser engraving machines are provided on the laser engraving station, and the number of laser engraving machines faces different surfaces of the product. The transfer mechanism comprises a base movably coordinated with the conveyor line, a left limit plate fixedly arranged on the left side of the base, a right limit plate arranged on the right side of the base, a horizontal horizontal cylinder installed on the bottom of the base and connected to the right limit plate, as well as a front limit plate fixedly arranged at the front end of the base, a horizontal longitudinal cylinder arranged on the right side of the base, a rotating cylinder installed on the horizontal longitudinal cylinder, and a rear limit plate installed on the rotating cylinder.

[0005] The base has a front stop plate on the front, a left stop plate on the left side, and a right stop plate on the right side. The rear stop plate is upright and located on the right side of the base. This creates a loading notch at the rear of the base, allowing products to be placed on the base from top to bottom. For larger products, the rear of the product may protrude backwards through the loading notch, allowing the notch to accommodate products of varying sizes.

[0006] The transfer mechanism is located at the loading station. The product is placed on the base. The horizontal transverse cylinder drives the right limit plate to move toward the left limit plate. The left and right limit plates clamp the product left and right. The horizontal longitudinal cylinder drives the rotary cylinder and the rear limit plate to move backward, so that the rear limit plate is located on the right side behind the product. After that, the rotary cylinder drives the rear limit plate to rotate 90 degrees to the left and downward. The rear limit plate is horizontal and located behind the product. After that, the horizontal longitudinal cylinder resets and drives the rear limit plate forward. The rear limit plate and the front limit plate clamp the product front and back. In this way, the front, back, left and right of the product are effectively positioned. The positioning reference is the front limit plate and the left limit plate fixed on the base. Due to the movable setting of the right limit plate and the rear limit plate, the transfer mechanism can accommodate products of various sizes and clamp them.

[0007] Under the transmission of the conveyor line, the transfer mechanism comes to the laser engraving station, and several laser engraving machines perform laser engraving on different surfaces of the product.

[0008] The base is provided with a transverse clearance groove, and the right limit plate is provided with a right limit plate extension extending downward. The right limit plate extension is located in the transverse clearance groove, and the horizontal transverse cylinder is connected to the right limit plate extension. The transverse clearance groove provides conditions for the right limit plate to clamp the product.

[0009] The loading station is equipped with a rotary gripper mechanism, consisting of a rotating body mounted on a bracket, a turntable connected to the rotating body, vertical loading cylinders mounted on either side of the turntable, and gripper cylinders mounted on the vertical loading cylinders. The rotating body is pivotally connected to the bracket and can be driven by a motor mounted on the bracket through a transmission mechanism. While the gripper cylinder on one side of the turntable grips a product on the loading conveyor line, the gripper cylinder on the other side places the gripped product on the transfer mechanism. The turntable then rotates 180 degrees, and the unloaded gripper cylinder grips the product on the loading conveyor line, while the other gripper cylinder places the gripped product on the transfer mechanism. This repeated process improves work efficiency.

[0010] The conveyor line consists of a horizontal guide rail and a horizontal screw mounted on a working base. The horizontal screw is driven by the conveyor line motor. The base is equipped with a slider that mates with the horizontal guide rail and is connected to the screw nut. Driven by the horizontal screw, the transfer mechanism moves back and forth between the loading station and the laser engraving station.

[0011] The laser engraving machine includes a top laser engraving machine and a side laser engraving machine. The top laser engraving machine is installed on the first column, and the side laser engraving machine is installed on the second column. The top laser engraving machine engraves the top surface of the product, while the side laser engraving machine engraves the side of the product.

[0012] The first column is equipped with a first vertical screw mechanism, whose screw nut is connected to the first lifting base. The top laser engraving machine is mounted on the first lifting base. A motor driving the first vertical screw mechanism is located at the top of the first column. The second column is equipped with a second vertical screw mechanism, whose screw nut is connected to the second lifting base. The side laser engraving machine is mounted on the second lifting base. A handle driving the second vertical screw mechanism is located at the top of the second column. Driven by the motor, the top laser engraving machine can be raised and lowered along the first column to accommodate different products. Workers can manually rotate the handle to drive the side laser engraving machine to raise and lower according to the product.

[0013] The utility model provides a mechanical structure for an automated laser engraving device, which is beneficial for the laser engraving device to be adaptable to a variety of products and capable of laser engraving multiple surfaces of the products. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1 、 Figures 3 to 5 A multi-product multi-surface laser engraving mechanism compatible with multiple products includes a conveyor line 20 arranged on a working base plate 10, and a transferring mechanism 30 arranged on the conveyor line. The working base plate is divided into a loading station and a laser engraving station according to the conveying direction of the conveyor line. Several laser engraving machines are provided on the laser engraving station, and the several laser engraving machines face different surfaces of the product. The transferring mechanism 30 includes a base 31 movably coordinated with the conveyor line, a left limit plate 32 fixedly arranged on the left side of the base, a right limit plate 33 arranged on the right side of the base, a horizontal horizontal cylinder 331 installed at the bottom of the base and connected to the right limit plate, as well as a front limit plate 34 fixedly arranged at the front end of the base, a horizontal longitudinal cylinder 351 arranged on the right side of the base, a rotating cylinder 352 installed on the horizontal longitudinal cylinder, and a rear limit plate 35 installed on the rotating cylinder.

[0029] The base 31 is provided with a transverse groove 310 , and the right limit plate 33 is provided with a right limit plate extension 332 extending downward. The right limit plate extension is located in the transverse groove, and the horizontal transverse cylinder 331 is connected to the right limit plate extension.

[0030] like Figure 1 、 Figure 2 The loading station is equipped with a rotary clamping mechanism 40, which includes a rotating body 41 mounted on a bracket, a turntable 42 connected to the rotating body, vertical loading cylinders 43 mounted on both sides of the turntable, and a clamping cylinder 44 mounted on the vertical loading cylinder. The rotating body 41 is pivotally connected to the bracket and can be driven by a motor mounted on the bracket through a transmission mechanism.

[0031] like Figure 1 The conveyor line 20 includes a horizontal guide rail 21 and a horizontal screw 22 installed on the working base plate 10. The horizontal screw is driven by the conveyor line motor 23. The base 31 is provided with a slider that cooperates with the horizontal guide rail, and the base is connected to the screw nut.

[0032] The laser engraving machine includes a top laser engraving machine 51 and a side laser engraving machine 52 . The top laser engraving machine is installed on a first column 53 , and the side laser engraving machine is installed on a second column 54 .

[0033] A first vertical screw mechanism is provided on the first column 53, the screw nut of the first vertical screw mechanism is connected to the first lifting seat 531, the top laser engraving machine 51 is installed on the first lifting seat, and a motor 532 for driving the first vertical screw mechanism is provided on the top of the first column; a second vertical screw mechanism is provided on the second column 54, the screw nut of the second vertical screw mechanism is connected to the second lifting seat 541, the side laser engraving machine 52 is installed on the second lifting seat, and a handle 542 for driving the second vertical screw mechanism is provided on the top of the second column.

[0034] A front stop plate 34 is located in front of the base 31, a left stop plate 32 is located on the left side of the base, and a right stop plate 33 is located on the right side of the base. A rear stop plate 35 is in an upright position and located on the right side of the base 31. Thus, the rear of the base becomes a loading notch, and products 90 are placed from top to bottom on the base 31. If the product is large, the rear of the product may protrude backward from the loading notch, thus accommodating products of different sizes.

[0035] While the gripper cylinder 44 on one side of the turntable 42 is gripping a product on the loading conveyor line, the gripper cylinder on the other side of the turntable places the gripped product on the transfer mechanism 30. The turntable 42 then rotates 180 degrees, and the unloaded gripper cylinder 44 grips the product on the loading conveyor line, while the other gripper cylinder places the gripped product on the transfer mechanism 30. This process repeats, with the rotating gripper mechanism 40 transferring products from the loading conveyor line to the transfer mechanism 30 one by one.

[0036] The transfer mechanism 30 is located at the loading station. The product is placed on the base 31. The horizontal transverse cylinder 331 drives the right limit plate 33 toward the left limit plate 32, clamping the product horizontally with the left and right limit plates. The horizontal longitudinal cylinder 351 drives the rotary cylinder 352 and the rear limit plate 35 to move backward, positioning the rear limit plate 35 to the right, 90 degrees behind the product. The rotary cylinder 352 then drives the rear limit plate 35 to rotate 90 degrees left and downward, positioning the rear limit plate 35 horizontally and behind the product. The horizontal longitudinal cylinder 351 then resets, driving the rear limit plate 35 forward. The rear limit plate 35 and the front limit plate 34 clamp the product front-to-back. In this way, the product is effectively positioned front, back, left, and right. The positioning reference is the front limit plate 34 and left limit plate 32 fixed to the base 31. Due to the movable arrangement of the right limiting plate 33 and the rear limiting plate 35 , the transfer mechanism 30 can accommodate products of various sizes and clamp them.

[0037] Under the transmission of the conveyor line 20, the transfer mechanism 30 comes to the laser engraving station, the top laser engraving machine 51 laser engraves the upper surface of the product, and the side laser engraving machine 52 laser engraves the side of the product.

[0038] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation method and application scope. The content of this specification should not be understood as limiting the present invention.
