Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a laser marking machine. Background Technique

[0002] Processing on a composite material film using a laser marking machine is a common production method for making temporary license plates nowadays.

[0003] The commonly used laser marking machine generally includes a long strip-shaped carrier board, which is positioned above the conveying platform along the width direction of the conveying platform. The material storage mechanism is positioned above the conveying platform and is arranged opposite to the carrier board. Moreover, a number of roller frames are arranged at intervals along the conveying direction of the conveying platform on the conveying platform, which are used to flatten and tension the composite material film during the conveying process. A number of laser marking heads driven by cylinders are installed on one side surface of the carrier board, and these laser marking heads are arranged at intervals along the width direction of the conveying platform. Under the driving action of the cylinders, the number of laser marking heads can move up and down to achieve marking processing on the composite material film.

[0004] However, in the actual production process, the marking speed of the laser marking machine is not matched with the conveying speed of the composite material film by the conveying platform. Usually, the conveying speed of the conveying platform is faster than the marking speed of the laser marking machine, which results in the formed composite material film not meeting the actual manufacturing standards required. Therefore, in the prior art, in order to effectively avoid this phenomenon, generally, a material storage mechanism arranged opposite to the laser marking machine is set on the conveying platform, so that the composite material film first passes through the material storage mechanism for turnover and then is output through the conveying platform, thereby reducing the speed and buffering the conveying speed of the composite material film, so that the conveying speed of the conveying platform and the marking speed of the laser marking machine tend to be consistent, and further ensuring the marking quality.

[0005] However, in recent years, with the continuous improvement of living standards, consumers' demand for purchasing cars has also increased day by day. Therefore, the demand for the number of temporary license plates is also increasing more and more. Thus, the demand for this converted composite material film is also continuously increasing. Using the above-mentioned laser marking machine for production work, although it can ensure that the quality of the produced composite material film meets the standards, the production efficiency is extremely limited and cannot meet the actual production requirements. Summary of the Invention

[0006] The purpose of the utility model is to propose a laser marking machine in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is: how to improve the production efficiency of the composite material film.

[0007] The object of the present utility model can be achieved by the following technical solutions: A laser marking machine, comprising a plurality of marking heads, characterized in that the laser marking machine further comprises two sets of oppositely arranged mounting frames, each set of the mounting frames comprising a mounting plate, a positioning plate and a fixing plate which are strip-shaped and horizontally arranged, the positioning plate is slidably connected to the fixing plate along the length direction of the fixing plate, the mounting plate is slidably connected to the positioning plate along the length direction of the positioning plate and can be positioned, and a plurality of the marking heads are fixedly arranged at intervals along the length direction on the side surfaces of the two mounting plates facing each other.

[0008] The laser marking machine assembles the marking heads through the mounting plate, and connects the mounting plate and the positioning plate in a sliding connection manner. Since the composite material films are bundled, when spread out, they have a very long length and a very considerable weight. In the prior art, it is very inconvenient to manually adjust the position of the composite material films. During the marking work, the worker can slide and adjust the initial position of the mounting plate according to the requirements of the marking position, and make it remain positioned at this position after the adjustment. Thus, the initial positions of the marking heads on each mounting plate can be re-determined according to the marking positions of composite material films of different sizes, thereby ensuring the processing accuracy. During the production process, there is no need to move and adjust the position of the composite material films, ensuring convenient operation. And on this basis, the positioning plate is also connected to the fixing plate in a sliding connection manner. During the marking work, the positioning plate can drive the mounting plate to reciprocate along the length direction of the fixing plate, that is, to realize that each marking head can reciprocate along the width direction of the conveying platform during the marking work. Thus, it is ensured that each marking head can perform one-time processing on the composite material film in each area of the composite material film. On the basis of the above structure, the present application adopts a cooperation and collaborative processing method of two sets of laser marking machines to replace the storage mechanism and the laser marking machine in the prior art. While reasonably utilizing the space on the conveying platform, the actual conveying speed of the conveying platform is adapted by the simultaneous operation of the two sets of laser marking machines, which can effectively avoid the situation that the marking speed and the conveying speed do not match, ensure that the quality of the marked composite material film meets the production requirements, and at the same time, on the basis of this advantage, ensure the further improvement of production efficiency.

[0009] In the above laser marking machine, a driving motor is installed on the positioning plate. On one side surface of the fixing plate facing the positioning plate, a rack is fixed along the length direction. A gear meshing with the rack is fixed on the driving shaft of the driving motor. As a specific solution, the driving motor fixed on the positioning plate and having a gear at the driving end is matched with the rack fixed on the fixing plate, so that under the drive of the driving motor, the positioning plate can drive the carrying plate to perform automatic reciprocating movement along the length direction of the fixing plate. As an alternative solution, a lead screw can also be fixed on the driving end of the driving motor, and a nut is fixed on the surface of the fixing plate. The driving motor drives the lead screw to rotate and thread-fit with the nut, so as to achieve the effect that the driving positioning plate can drive the carrying plate to perform automatic reciprocating movement along the length direction of the fixing plate.

[0010] In the above laser marking machine, on one side surface of the fixing plate facing the positioning plate, a first slide rail is also fixed along the length direction. A first slider is fixed on one side surface of the positioning plate facing the fixing plate. The first slider is slidably connected to the first slide rail. And the first slide rail and the first slider provided between the fixing plate and the positioning plate are connected in a sliding fit manner, so as to play a role in connecting the fixing plate and the positioning plate, and can play a guiding effect on the positioning plate.

[0011] In the above laser marking machine, there are two first slide rails, which are arranged close to the two side edges of the surface of the fixing plate. There are four first sliders, which are arranged close to the circumferential corners of the surface of the positioning plate. Two of the first sliders are slidably connected to one of the first slide rails, and the other two first sliders are slidably connected to the other first slide rail. This further ensures the connection stability between the positioning plate and the fixing plate.

[0012] In the above laser marking machine, two heightening rods are fixed on one side surface of the fixing plate facing the positioning plate along the horizontal direction. The two heightening rods are arranged close to the two side edges of the surface of the positioning plate. The two first slide rails are fixed on the two heightening rods. Through this setting, the two first slide rails are arranged closer to the positioning plate. While ensuring that the first slider and the first slide rail can be fully slidably matched, it ensures that sufficient space is provided for the connection between the gear on the motor shaft and the rack, thereby avoiding interference.

[0013] In the above-mentioned laser marking machine, a second slide rail is fixed along the length direction on the side surface of the positioning plate facing the mounting plate, and a second slider is fixed on the side surface of the mounting plate facing the positioning plate, and the second slider is slidably connected with the second slide rail. Through this arrangement, the second right slider cooperates with the second slide rail to slide and connect to achieve the position adjustment of the mounting plate, and on the basis of this solution, after the adjustment is completed, the mounting plate and the positioning plate can be screwed and locked with screws, thereby avoiding the position deviation of the mounting plate during the marking process.

[0014] In the above-mentioned laser marking machine, the two slide rails are arranged near the two side edges of the positioning plate, the four sliders are arranged near the circumferential corners of the mounting plate, two of the sliders are slidably connected to one of the two slide rails, and the other two sliders are slidably connected to the other two slide rails. This further ensures the connection stability between the mounting plate and the positioning plate.

[0015] Compared with the existing technology, this laser marking machine has the following advantages:

[0016] 1. The marking head is installed through the carrying plates on the two sets of carrying racks, and the marking machine is installed on the conveying platform. The marking work is carried out through the marking heads on the two sets of carrying racks, thereby eliminating unnecessary material storage mechanisms on the basis of the existing technology, and reasonably utilizing the space on the conveying platform, effectively controlling the production cost while ensuring the marking work efficiency.

[0017] 2. In each group of mounting frames, the mounting plate can slide and position along the length direction of the positioning plate, so that the position of each marking head on the mounting plate corresponding to the composite material film can be accurately adjusted before marking. In addition, the positioning plate, the mounting plate and the marking heads can be driven during the marking process through the transmission cooperation of the driving motor and the rack, ensuring unmanned operation during the entire marking process.

Specific implementation manner

[0025] The following are specific embodiments of the present invention and, in combination with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0026] As Figure 1 shown in Figure 2 the figure, this laser marking machine includes two sets of carrying racks 2 arranged oppositely. Combining Figures 3 - 6 with Figure 3 the figure, each set of carrying racks 2 includes a horizontally arranged carrying plate 21, a positioning plate 22, and a fixing plate 23 that are in a long strip shape. The carrying plate 21, the positioning plate 22, and the fixing plate 23 are arranged in parallel. As

[0027] shown in Figures 4 - 6As shown in the figure, on the circumferential corners of the side plate surface of the positioning plate 22 facing the fixed plate 23, a first slider 222 is fixed. On the side plate surface of the fixed plate 23 facing the positioning plate 22, two square rod-shaped heightening rods 233 are fixed horizontally. The two heightening rods 233 are arranged close to the two side edges of this side plate surface of the fixed plate 23, and two first slide rails 232 are also fixed on this side plate surface of the fixed plate 23. The two first slide rails 232 are horizontally arranged and are fixedly connected to the two heightening rods 233 in a one-to-one correspondence. Among them, two first sliders 222 are slidably connected to one of the first slide rails 232, and the other two first sliders 222 are slidably connected to the other first slide rail 232. A shaft-passing hole penetrating through its two side surfaces is opened at one end of the positioning plate 22. A driving motor 221 whose driving end is perpendicular to the plate surface of the positioning plate 22 is fixed on the positioning plate 22. The driving end of the driving motor 221 passes through the shaft-passing hole and is fixed with a gear 2211. On the side plate surface of the fixed plate 23 facing the positioning plate 22, a rack 231 is fixed between the two first slide rails 232 and is horizontally arranged, and the gear 2211 meshes with the rack 231.

[0028] It is worth mentioning that the two sets of mounting frames 2 of this laser marking machine are both fixed on the conveying platform through the fixed plate 23 with bolts, so that the two sets of mounting frames 2 are arranged oppositely.

[0029] Working principle: Before operation, the worker can adjust the position of the mounting plate 21 according to composite material films of different sizes, that is, push or pull the mounting plate 21, so that it slides on the positioning plate 22 through the cooperation of the second slide rail 223 and the second slider 211, ensuring that the initial positions of the marking heads 1 on the mounting plate 21 coincide with the processing positions of the composite material films conveyed on the conveying platform. It should be mentioned here that during the subsequent working process, the position of the mounting plate 21 remains stationary relative to the positioning plate 22. Therefore, after the position of the mounting plate 21 is adjusted, the worker can screw and lock the mounting plate 21 to the positioning plate 22 through bolts, so as to ensure that the mounting plate 21 can be firmly positioned on the positioning plate 22. Then the worker can start the driving motor 221, so that the rotation of the gear 2211 meshes with the rack 231, thereby driving the positioning plate 22 to move back and forth along the length direction of the fixed plate 23 under the combined drive of the gear 2211 and the rack 231 and the guiding of the first slider 222 and the first slide rail 232, driving the mounting plate 21 and the marking heads 1. In addition, the marking heads 1 move up and down relative to the conveying platform under the drive of the air cylinders, thereby ensuring that the marking work can be carried out in a manner of unmanned intelligent control.

Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0031] Although terms such as marking head 1, carrying frame 2, carrying board 21, slider two 22, positioning plate 221, driving motor 2211, gear 2211, slider one 211, slide rail two 223, fixing plate 23, rack 231, slide rail one 232, heightening rod 233 are used more frequently herein, the possibility of using other terms is not excluded.
