Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, specifically an automated toy laser marking machine. Background Technology

[0002] Toy laser marking machines are laser marking devices specifically designed for the toy industry. They are mainly used to engrave various information on the surface of toys. Laser marking machines utilize high-energy-density lasers to locally irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thus leaving a permanent mark. When a crystal rod is excited, it emits a highly focused laser beam that scans the workpiece along a fixed trajectory. The laser energy is instantly converted into heat energy, causing the surface material of the workpiece to undergo a rapid physical or chemical reaction, thereby engraving numbers, symbols, and icons on the workpiece surface. It is widely used in toy production.

[0003] However, in practice, it has been noted that when marking toys, the toys are usually disassembled into individual parts for marking. When marking toy parts, a certain period of time needs to be waited for the toy parts to remain still. However, in actual use, if the marking machine is hit or the toy parts are affected by airflow, the toy parts will shift, resulting in the marking pattern shifting and affecting the marking accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an automated laser marking machine for toys. By using elastic positioning posts arranged in a rectangular array within a limiting frame, the staggered positions of these posts create positioning grooves for the toy based on its size and shape. This allows for rapid positioning of the toy before marking, ensuring it is directly beneath the laser marker and guaranteeing marking accuracy. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated toy laser marking machine includes a worktable, a laser marking device above the worktable, and a positioning mechanism for positioning the toy directly below the laser marking device. The positioning mechanism is fixedly connected to the worktable, and a positioning mounting slot for mounting the positioning mechanism is provided on the worktable.

[0007] The positioning mechanism includes an electromagnetic adsorber fixed in the positioning mounting slot. The electromagnetic adsorber is equipped with a limiting frame that is bolted to the worktable, and the limiting frame is movably connected with elastic positioning columns in a rectangular array.

[0008] As a further technical solution of this utility model, the elastic positioning column includes a sliding column placed in the limiting frame, and a T-shaped magnetic isolation seat that penetrates the limiting frame is fixedly connected to the bottom of the sliding column, and an armature is embedded in the bottom of the T-shaped magnetic isolation seat.

[0009] As a further technical solution of this utility model, the electromagnetic adsorber includes an insulating plate bolted to the positioning mounting groove, and an electromagnet column corresponding to the armature is fixedly connected above the insulating plate, and the electromagnet column is located above the armature.

[0010] As a further technical solution of this utility model, the limiting frame includes an insulating outer frame, the bottom of which is fixedly connected to a limiting base plate, and the limiting base plate is provided with a through hole corresponding to the T-shaped magnetic isolation seat, and the end of the T-shaped magnetic isolation seat slides in cooperation with the through hole.

[0011] As a further technical solution of this utility model, each of the T-shaped magnetic isolation seats is fitted with a reset spring on the outside, and the reset spring is located above the limiting base plate, while the other end of the reset spring is attached to the bottom of the sliding column, and the armature is located below the limiting base plate.

[0012] As a further technical solution of this utility model, the positioning mechanism is provided with a lifting and moving frame fixedly connected to the worktable at the rear, and an extension arm is installed on the side of the lifting and moving frame, which is parallel to the top of the worktable, and the end of the extension arm is fixedly connected to the laser marking device.

[0013] As a further technical solution of this utility model, a display is fixedly connected to the side of the lifting and moving frame away from the extension arm, and an electrical controller fixedly connected to the workbench is provided below the display.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, pressing down on the sliding column moves the armature below the sliding column into the magnetic field range of the electromagnet column, thereby causing the electromagnet column to generate a downward attractive force on the sliding column. At this time, the attractive force generated by the electromagnet column is greater than the spring force of the return spring. Therefore, the pressed sliding column is lower than the top of the insulating outer frame, while the other sliding columns that are not pressed, because the armature below them has not entered the magnetic field range of the electromagnet column, remain flush with the top of the insulating outer frame under the action of the return spring.

[0016] 2. In this utility model, since the sliding columns are arranged in a rectangular array, the height difference between multiple elastic positioning columns creates a groove for positioning on the elastic positioning columns. Furthermore, since the sliding columns are arranged in a rectangular array, the height between the elastic positioning columns at different positions can be adjusted at any time according to the size and shape of the toy, thereby enabling quick positioning of toy parts of different shapes and improving work efficiency.

[0017] 3. In this utility model, the bottom limiting plate of the insulating outer frame is provided with a through hole corresponding to the sliding column, and the T-shaped magnetic isolation seat slides in cooperation with the through hole. The insulating outer frame limits the sliding columns arranged in a rectangular array, and the sliding cooperation between the T-shaped magnetic isolation seat and the through hole can ensure that the sliding column moves vertically, prevent the sliding column from deviating during movement, and improve the positioning effect.

Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-7 This utility model provides an automated toy laser marking machine, including a worktable 1, a laser marking device 6 above the worktable 1, and a positioning mechanism for positioning the toy directly below the laser marking device 6. The positioning mechanism is fixedly connected to the worktable 1, and a positioning mounting groove 9 for mounting the positioning mechanism is provided on the worktable 1.

[0029] The positioning mechanism includes an electromagnetic adsorber 11 fixed in the positioning mounting groove 9. The electromagnetic adsorber 11 is provided with a limiting frame 7 bolted to the workbench 1, and the limiting frame 7 is movably connected with elastic positioning columns 8 in a rectangular array.

[0030] Furthermore, the elastic positioning post 8 includes a sliding post 81 placed in the limiting frame 7, and a T-shaped magnetic isolation seat 82 that penetrates the limiting frame 7 is fixedly connected to the bottom of the sliding post 81, and an armature 84 is embedded in the bottom of the T-shaped magnetic isolation seat 82.

[0031] By adopting the above technical solution, since the sliding columns 81 are arranged in a rectangular array, the height difference between the multiple elastic positioning columns 8 forms a groove for positioning on the elastic positioning columns 8. Furthermore, since the sliding columns 81 are arranged in a rectangular array, the height between the elastic positioning columns 8 at different positions can be adjusted at any time according to the size and shape of the toy, thereby enabling the rapid positioning of toy parts of different shapes.

[0032] Furthermore, the electromagnetic adsorber 11 includes an insulating plate 111 bolted to the positioning mounting groove 9, and an electromagnet post 112 corresponding to the armature 84 is fixedly connected above the insulating plate 111, and the electromagnet post 112 is located above the armature 84.

[0033] Furthermore, the limiting frame 7 includes an insulating outer frame 71, the bottom of which is fixedly connected to a limiting base plate 72, and the limiting base plate 72 is provided with a through hole 73 corresponding to the T-shaped magnetic shielding seat 82, and the end of the T-shaped magnetic shielding seat 82 is slidably engaged with the through hole 73.

[0034] By adopting the above technical solution, the limiting base plate 72 at the bottom of the insulating outer frame 71 is provided with a through hole 73 corresponding to the sliding column 81, and the T-shaped magnetic shielding seat 82 slides and engages with the through hole 73. The insulating outer frame 71 limits the sliding column 81 arranged in a rectangular array, and the sliding engagement between the T-shaped magnetic shielding seat 82 and the through hole 73 can ensure that the sliding column 81 moves vertically, prevent the sliding column 81 from deviating during movement, and improve the positioning effect.

[0035] More specifically, each of the T-shaped magnetic isolation seats 82 is fitted with a reset spring 83 on its outer side, and the reset spring 83 is located above the limiting base plate 72, while the other end of the reset spring 83 is in contact with the lower part of the sliding column 81, and the armature 84 is located below the limiting base plate 72.

[0036] Furthermore, the positioning mechanism is provided with a lifting and moving frame 3 fixedly connected to the worktable 1 at the rear, and an extension arm 5 is installed on the side of the lifting and moving frame 3, which is parallel to the top of the worktable 1, and the end of the extension arm 5 is fixedly connected to the laser marking device 6.

[0037] Furthermore, a display 4 is fixedly connected to the side of the lifting and moving frame 3 away from the extension arm 5, and an electrical controller 10 fixedly connected to the workbench 1 is provided below the display 4.

[0038] By adopting the above technical solution, pressing down on the sliding column 81 moves the armature 84 below the sliding column 81 into the magnetic field range of the electromagnet column 112, thereby causing the electromagnet column 112 to generate a downward attraction force on the sliding column 81. At this time, the attraction force generated by the electromagnet column 112 is greater than the spring force of the return spring 83. Therefore, the pressed sliding column 81 is lower than the top of the insulating outer frame 71, while the other unpressed sliding columns 81, because the armature 84 below them has not entered the magnetic field range of the electromagnet column 112, remain flush with the top of the insulating outer frame 71 under the action of the return spring 83.

[0039] More specifically, the electrical controller 10 is equipped with a switch to control the current of the electromagnet column 112, and the switch is electrically connected to the coil on the electromagnet column 112. The electrical controller 10 is also equipped with a switch to control the current of the display 4 and the laser marking device 6. When the switch is turned on, the laser marking device 6 will enter the standby state.

[0040] The display 4 and the laser marking device 6 are electrically connected via a data connection cable. The pattern stored on the display 4 is transmitted to the laser marking device 6 after digital-to-analog conversion. The laser marking device 6 then emits a laser beam downwards, and the corresponding pattern is etched onto the surface of the toy by the high temperature of the laser beam (the above laser marking technology adopts conventional technology in this field, and its working principle is well known to those skilled in the art, so it will not be described in detail).

[0041] Furthermore, when the sliding column 81 moves downward, it will squeeze the return spring 83 until the armature 84 below the sliding column 81 enters the magnetic field adsorption range of the electromagnet column 112. At this time, the downward attraction of the electromagnet column 112 is greater than the elasticity of the return spring 83.

[0042] When the reset spring 83 is fully extended, the armature 84 below the sliding column 81 is located above the magnetic field range of the electromagnet column 112. At this time, the electromagnet column 112 will not generate an attraction force on the armature 84. In daily use, it is necessary to strengthen the inspection, maintenance and upkeep of each component, especially the spring. When the spring is fatigued or deformed and is no longer able to perform the reset function, it needs to be replaced in time.

[0043] The working principle of this utility model is as follows: First, the electromagnet column 112 on the electromagnetic adsorber 11 is energized. The electromagnet column 112 generates a magnetic field around it. At this time, the armature 84 below the sliding column 81 is positioned above the magnetic field, so the magnetic field generated by the electromagnet column 112 is insufficient to attract the armature 84. Then, the toy is pressed downwards, and according to the shape of the toy, the sliding column 81 at the corresponding position moves downwards, causing the armature 84 below the sliding column 81 to adhere to the electromagnet column 112. This allows the armature 84 to enter the magnetic field generated by the electromagnet column 112, and the electromagnet column 112 can attract the armature 84. 4. Adsorption occurs, while parts not pressed remain at the top. Based on the different heights of the sliding columns 81, positioning grooves are formed on the elastic positioning columns 8 arranged in a rectangular array. Before marking, toy parts can be directly placed into the grooves for quick positioning, positioning the toy directly below the laser marker 6. Then, the electrical controller 10 powers on the laser marker 6 and the display 4. The graphics on the display 4 are converted into digital signals and transmitted to the laser marker 6, enabling the laser marker 6 to perform marking operations on the toy surface. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
