Description

Technical Field

[0001] The utility model relates to the technical field of laser marking, in particular to a high-speed laser marking device. Background Art

[0002] A laser marking machine is a device that uses a laser beam as a processing medium and, through computer control, performs high-speed and high-precision non-contact engraving, marking, or cutting on the surface of materials. It utilizes the high energy density characteristics of the laser to quickly and clearly mark information such as text, patterns, and two-dimensional codes on the surfaces of various materials. It has the advantages of fast marking speed, high precision, no wear, and strong permanence, and is widely used in fields such as product identification, anti-counterfeiting traceability, and personalized customization in industrial production.

[0003] A highly automated high-speed laser marking device with the publication number CN214721497U includes a bracket; an operating table is provided inside the bracket, a rotating device is installed at the central position on the top of the operating table, and a laser pen is installed on one side of the laser machine; in the utility model, a protection mechanism is installed on the top of the rotating device. An infrared emitter emits an infrared beam that irradiates the inner top of the L-shaped baffle. When a person accidentally puts their hand into the top of the rotating device, the infrared beam is blocked and then the industrial controller receives the instruction, and then sends the instruction to the host to stop the laser machine from working. A purification mechanism is equidistantly installed inside the L-shaped baffle. The suction force generated by the rotation of the fan conveys external gas into the device. Then, under the action of a high-voltage electric field, a large number of positive and negative oxygen ions are generated by the plasma generator to deodorize the gas, and the deodorized and purified gas will be discharged from the other side of the device, thereby improving the working environment of people.

[0004] However, during the laser marking process of the existing device on materials, only one working station for placing materials is provided. At this time, there is a waste of time involved in loading and unloading materials, resulting in the inability of the laser marking machine to operate when replacing materials, causing a waste of time and thus reducing the laser marking efficiency. Summary of the Utility Model

Detailed Embodiments

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as upper, lower, left, right, front, rear, inner and outer that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model and do not specifically limit the present utility model.

[0025] Embodiment: A high-speed laser marking device, as Figure 1 and Figure 2 shown, includes a supporting box 1, a support frame 2, a laser marking assembly 3 and a control panel 4. The bottom of the supporting box 1 is connected to the support frame 2. The laser marking assembly 3 and the control panel 4 are installed on the supporting box 1. The control panel 4 is used to control the laser marking assembly 3 to complete the laser marking work. It also includes a material changing assembly and a discharging assembly. A material changing assembly is provided on the supporting box 1 for replacing the materials for laser marking. A discharging assembly is provided on one side of the supporting box 1 for discharging the marked materials.

[0026] As Figure 2 and Figure 3 shown, the material changing assembly includes a rotating disk 5, a placing rack 6, a motor 61, a driving shaft 62, a driving frame 63 and a positioning frame 64. The rotating disk 5 is rotatably connected to the middle of the supporting box 1. The placing rack 6 is hinged to the rotating disk 5 and is located around the rotating disk 5. The motor 61 is installed at the bottom of the supporting box 1. The output shaft of the motor 61 is connected to the driving shaft 62. The driving shaft 62 is rotatably connected inside the supporting box 1. The driving shaft 62 is connected to the driving frame 63. The bottom of the rotating disk 5 is connected to the positioning frame 64. The driving frame 63 is in transmission cooperation with the positioning frame 64.

[0027] As Figure 4 and Figure 5 shown, the discharging assembly includes a blanking plate 7, a medium-length cylinder 71, a roller seat 72, a reset pulling rope 73, a reset spring 74 and a top plate 75. The bottom of one side of the supporting box 1 is connected to a downwardly inclined blanking plate 7. The medium-length cylinder 71 is installed at the bottom of the upper end of the blanking plate 7. The top of the medium-length cylinder 71 is connected to the roller seat 72. The roller seat 72 is in pressing cooperation with the placing rack 6. The top plate 75 is slidably connected inside the rotating disk 5. The number of the top plates 75 is the same as that of the placing racks 6. One end of the reset pulling rope 73 is connected to the bottom of the placing rack 6, and the other end is connected to the top plate 75. A reset spring 74 is provided inside the rotating disk 5. One end of the reset spring 74 away from the placing rack 6 is connected to the top plate 75, and the other end is connected inside the rotating disk 5. When the placing rack 6 is inclined for discharging, the reset spring 74 is in a compressed state. The control panel 4 is electrically connected to the medium-length cylinder 71 and the motor 61 respectively.

[0028] As Figure 4 shown, it also includes a buffer sponge 8. The upper surface of the blanking plate 7 is connected with a buffer sponge 8 for buffering the movement of the materials.

[0029] Four placing racks 6 are hinged on the rotating disk 5. The ones located below the laser marking assembly 3 are at the marking position, the ones located above the blanking plate 7 are at the blanking position, the position opposite to the marking position is the loading position, and the position opposite to the blanking position is the waiting position. Thus, after the staff turns on the control panel 4 and the laser marking assembly 3, the marking pattern and the moving track of the laser marking assembly 3 are programmed through the control panel 4. After the setting is completed, the laser marking assembly 3 can work according to the set program to mark the materials. When loading, the staff places the materials to be marked on the placing rack 6, and then turns on the motor 61. The motor 61 drives the driving rack 63 to rotate through the driving shaft 62. The driving rack 63 is in transmission cooperation with the positioning rack 64. Every time the driving rack 63 rotates 180 degrees, the positioning rack 64 rotates 90 degrees, thereby driving the rotating disk 5 to rotate 90 degrees, and the four placing racks 6 change positions. The placing rack 6 that has completed loading moves below the laser marking assembly 3 for marking. The marked materials follow the placing rack 6 and move to the blanking plate 7. Since the control panel 4 is electrically connected to the medium-length air cylinder 71 and the motor 61 respectively, when programming the control panel 4, the rotation speed of the motor 61 and the starting time of the medium-length air cylinder 71 can be controlled. According to the time required for the laser marking assembly 3 to mark, the rotation speed of the motor 61 is controlled. During the period when the driving rack 63 is disengaged from the positioning rack 64, the medium-length air cylinder 71 completes the blanking work. The specific steps are as follows: After the medium-length air cylinder 71 is started, the roller seat 72 rises, the roller seat 72 jacks up the placing rack 6, and the placing rack 6 rotates around the rotating disk 5 and rotates towards the blanking plate 7 side, so as to pour out the marked materials in the placing rack 6 and slide along the blanking plate 7 to complete the blanking. At this time, the rotating placing rack 6 pulls the reset pull rope 73, and the top plate 75 moves along with the reset pull rope 73, compressing the reset spring 74. Then the medium-length air cylinder 71 pulls the roller seat 72 to reset downward. Since the reset spring 74 is in a compressed state, after the placing rack 6 loses the support of the roller seat 72, under the action of the resilience of the reset spring 74, the top plate 75 slides back to its original position, and the placing rack 6 is pulled downward by the reset pull rope 73 to complete the reset. When the materials contact the blanking plate 7, they contact the buffer sponge 8 on the blanking plate 7, playing a buffering role to protect the materials.

[0030] As Figure 6 and Figure 7As shown in the figure, it further includes a clamping rod 9, a limiting plate 91, a small air cylinder 92, a rack 93, a gear 94, a V-shaped connecting rod 95, an elastic member 96 and a guide rod 97. The limiting plate 91 is slidably connected to the outside of the placement rack 6. Small air cylinders 92 are installed at both ends of the placement rack 6. The piston rod of the small air cylinder 92 is in transmission cooperation with the limiting plate 91. A plurality of placement grooves are provided on the placement rack 6 for placing materials to be marked. A guide rod 97 is connected inside the placement rack 6. The clamping rod 9 is slidably connected to the guide rod 97. A gear 94 is provided in the middle of the placement groove. The gear 94 is rotatably connected inside the placement rack 6. The guide rod 97 and the gear 94 are at different heights. The transverse guide rod 97 penetrates through all the placement grooves of the placement rack 6. Racks 93 are connected to the bottoms of the clamping rod 9 on the side close to the limiting plate 91 and the clamping rod 9 on the side far from the limiting plate 91, and both racks 93 are engaged with the gear 94. The rack 93 connected to the clamping rod 9 on the side close to the limiting plate 91 is fixedly connected to the limiting plate 91. A V-shaped connecting rod 95 is connected to the bottom of the limiting plate 91 connected to the rack 93. The V-shaped connecting rod 95 is located inside the placement rack 6, and the two V-shaped connecting rods 95 are slidably engaged with each other. An elastic member 96 is sleeved on the transverse guide rod 97. One end of the elastic member 96 is connected to the placement rack 6, and the other end is connected to the limiting plate 91 not connected to the rack 93. A rubber pad is provided inside the clamping rod 9 for protecting the material. When the clamping rod 9 is stationary, the elastic member 96 is in a stretched state.

[0031] The small air cylinder 92 is also electrically connected to the control panel 4. The control panel 4 controls the small air cylinder 92 to perform corresponding operations according to the position of the small air cylinder 92. The placement rack 6 rotates with the rotating disk 5. When it rotates to the feeding position, the small air cylinder 92 pushes the limit plate 91 to slide outwards. The limit plate 91 pulls the rack 93, and the rack 93 connected to the limit plate 91 pulls a clamping rod 9 to slide outwards. The sliding rack 93 meshes with the gear 94, and the gear 94 pushes another meshing rack 93 to slide inwards. Since the two clamping rods 9 connected with the V-shaped connecting rod 95 slide to both sides, the restriction on the other two clamping rods 9 is released. When the clamping rod 9 is stationary, the elastic member 96 is in a stretched state. Therefore, the elastic member 96 retracts and pulls the clamping rod 9 to slide along the guide rod 97. Since the guide rod 97 and the gear 94 are at different heights, the clamping rod 9 slides on the guide rod 97 without affecting the rotation of the gear 94. At this time, all four clamping rods 9 slide along the guide rod 97, leaving enough space in the middle to facilitate the placement of materials. Subsequently, the rotating disk 5 rotates another 90 degrees, and the placement rack 6 enters the waiting area. At this time, the control panel 4 controls the small air cylinder 92 to pull back the limit plate 91, thereby pulling the rack 93. Through the meshing of the gear 94, the clamping rod 9 connected with the rack 93 clamps the material towards the middle, and the V-shaped connecting rod 95 moves with the clamping rod 9, thereby pulling the clamping rod 9 connected with the elastic member 96 to slide towards the middle, clamping the material from all around to complete the fixation of the material. When the small air cylinder 92 pulls back the limit plate 91, when the force received is greater than the set threshold value, it indicates that the clamping rod 9 has clamped the material. At this time, the small air cylinder 92 is locked, so that the clamping rod 9 and the limit plate 91 maintain the current state, so that the material smaller than the placement groove can be centered in the placement groove to ensure the marking effect. When rotating towards the discharging position, the small air cylinder 92 pushes the limit plate 91 again to release the fixation of the material, without affecting the discharging work of the medium-long air cylinder 71, and the clamping rods 9 remain in a dispersed state, which is convenient for feeding when moving to the feeding position, thereby completing one cycle of work. By repeating this process, it can work continuously without waiting.

[0032] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
