Description

Technical Field

[0001] The utility model relates to the field of laser marking machines, in particular to a protective cover for laser marking machines. Background Art

[0002] A laser marking machine is a device that uses a laser beam to mark the surface of a workpiece. When in use, the workpiece needs to be clamped on the workpiece table. At this time, the laser head on the laser marking machine will generate a high-temperature laser beam, thereby forming a permanent mark on the surface of the workpiece. In view of the fact that the laser marking machine will generate a laser beam during operation, a protective cover is usually installed on the outside for safety reasons. Some protective covers, whether in the open or closed state, are located outside the laser marking machine, occupying a certain space from the outside, making the protective cover more susceptible to collision or interference from external objects, thereby affecting its normal opening and closing function, and may even cause a decrease in protective performance.

[0003] After searching, Chinese patent announcement number: CN219465119U discloses a protective cover for a laser marking machine, including a base and a cover body. The base is provided with a laser marking machine and a workpiece table. Guide rails are provided on both sides of the base. Both sides of the cover body are slidably connected to the guide rails. A driving mechanism for driving the cover body to move is provided on the base. A passing area is provided at the front end of the cover body. Door panel guide grooves are provided on both sides of the passing area. A lifting door panel is connected between the door panel guide grooves on both sides. A lifting driving device for driving the lifting door panel to move up and down is provided on the cover body. The utility model facilitates the clamping and taking of the workpiece through the movement of the cover body, and the movement of the cover body and the opening and closing of the lifting door panel are respectively completed by the driving mechanism and the lifting driving device, without manual operation, and is more convenient to use.

[0004] In the above technology, although there are certain improvements through the designed structure, it still has certain defects.

[0033] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a protective cover for a laser marking machine, including a marking machine body 1. The marking machine body 1 is a prior art, which is used for marking by laser and can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A through groove 1 3 is provided at the top of the front surface of the marking machine body 1, and a through groove 2 4 is provided at the front end of the inner wall of the through groove 1 3. The through groove 1 3 is connected to the through groove 2 4 to ensure that the connection distance between the clamping plate 22 and the rectangular shell 23 can be smoothly adjusted. A limiting groove 5 is provided on the inner wall of the through groove 2 4. A protective component 2 is provided on the inner wall of the marking machine body 1. A through groove 3 7 is provided on the upper surface of the marking machine body 1. The inner wall of the through groove 3 7 A rectangular groove 8 is provided, a cleaning component 9 is provided on the upper surface of the marking machine body 1, and the protection component 2 includes a protection frame 21. The protection frame 21 can prevent splashing impurities from injuring the operator, thereby improving safety. The protection frame 21 is slidably connected to the inner wall of the marking machine body 1, and a spring 25 is fixedly connected to the lower surface of the protection frame 21, and there are multiple groups of springs. The spring 25 always pushes the protection frame 21 to move upward through its own elasticity, ensuring that the protection frame 21 can be opened quickly, thereby improving convenience. At the same time, multiple groups are provided to ensure the smoothness of the movement. The bottom end of the spring 25 is fixedly connected to the inner wall of the marking machine body 1, and the top of the front surface of the protection frame 21 is fixedly connected to a rectangular shell 23, and the rectangular shell 23 contacts the inner wall of the through groove 3.

[0034] Reference Figure 4 , Figure 6The cleaning assembly 9 includes a cleaning shell 91, which contacts the inner wall of the through groove 7. A rectangular plate 92 is slidably connected to the inner wall of the cleaning shell 91. A clamping plate 93 is fixedly connected to the rear surface of the rectangular plate 92. The clamping plate 93 is adapted to the rectangular groove 8 to ensure the stability of the connection. The clamping plate 93 contacts the inner wall of the rectangular groove 8.

[0035] Reference Figure 3 The rear end of the upper surface of the marking machine body 1 is fixedly connected with a laser instrument support frame 10, and a sealing groove 6 is provided on the lower surface of the laser instrument support frame 10. A sealing strip 26 is fixedly connected to the upper surface of the protective frame 21. The sealing strip 26 is adapted to the sealing groove 6, and the connection is more stable under the action of a spring 25, thereby ensuring the sealing effect of the protective frame 21 and improving the protection. The top end of the sealing strip 26 contacts the inner wall of the sealing groove 6.

[0036] Reference Figure 3 , Figure 5 The inner wall of the rectangular shell 23 is slidably connected with a snap-on plate 22, and the front end of the snap-on plate 22 contacts the inner wall of the through groove 24. A rubber block 27 is fixedly connected to the lower surface of the snap-on plate 22. The rubber block 27 is made of rubber and has a certain elasticity. At the same time, the lower surface is set as an arc surface to ensure that the rubber block 27 can smoothly push the inner wall of the limiting groove 5. The rubber block 27 contacts the inner wall of the limiting groove 5. A transparent observation window 24 is fixedly connected to the inner wall of the front end of the protective frame 21, which is convenient for the operator to observe the product processing status. The transparent observation window 24 is made of transparent material.

[0037] Reference Figure 4 , Figure 6 The front surface of the rectangular plate 92 is elastically connected to a magnetic block 95 through a spring 2 94. The spring 2 94 itself has a certain elasticity, and its own elasticity can ensure that the rectangular plate 92 and the magnetic block 95 are in a level state. No matter who squeezes the spring 2 94, it will be reset by its elasticity. The magnetic block 95 is slidably connected to the inner wall of the cleaning shell 91 near the front side of the rectangular plate 92. One end of the spring 2 94 is fixedly connected to the front surface of the rectangular plate 92, and the other end of the spring 2 94 is fixedly connected to the rear surface of the magnetic block 95.

[0038] Reference Figure 4 A through slot 99 is provided on the upper surface of the cleaning shell 91, and a push plate 98 is slidably connected to the inner wall of the through slot 99. The lower surface of the push plate 98 is fixedly connected to the upper surface of the rectangular plate 92. The front surface of the magnetic block 95 contacts the magnetic plate 97. The magnetic block 95 and the magnetic plate 97 are special-shaped poles and will attract each other when in contact to ensure the stability of the connection. A cleaning cotton strip 96 is fixedly connected to the front surface of the magnetic plate 97, and the front surface of the cleaning cotton strip 96 contacts the rear surface of the transparent observation window 24.

[0039] Working principle: When the protection frame 21 needs to be opened, it is only necessary to pull the clamping plate 22 forward, and then push the rectangular shell 23 and the clamping plate 22 downward together. The rectangular shell 23 will drive the protection frame 21 to move downward, and the sealing strip 26 will also move downward with the protection frame 21 to break away from the inner wall of the sealing groove 6. At this time, the protection frame 21 will squeeze the spring 1 25 downward, and the rectangular shell 23 will completely enter the inner wall of the through groove 1 3. At this time, the clamping plate 22 is pushed back to make it enter the inner wall of the through groove 2 4. At this time, the rubber block 27 will enter the inner wall of the through groove 2 4 along with the clamping plate 22, and enter the inner wall of the limit groove 5 to form a clamping connection. In this way, the protective frame 21 can be hidden in the inner wall at the bottom end of the marking machine body 1 to avoid interfering with the operator's work. When it needs to be opened for protection, it is only necessary to pull the clamping plate 22. At this time, the rubber block 27 will be squeezed and separated from the inner wall of the limiting groove 5 until the front end of the clamping plate 22 is completely separated from the inner wall of the through groove 2 4. At this time, the clamping plate 22 can be loosened, and the spring 1 25 will push the protective frame 21 to move in the opposite direction through its own elasticity to protect the workbench. At this time, the sealing strip 26 will also be inserted into the inner wall of the sealing groove 6 as the protective frame 21 moves in the opposite direction for protection. It is quick and convenient, and the work efficiency is improved.

[0040] In the process of opening and closing the protection frame 21, the cleaning cotton strip 96 will always be in close contact with the inner wall of the protection frame 21 through the elasticity of the second spring 94. When the transparent observation window 24 overlaps with the cleaning cotton strip 96, the second spring 94 will use its own elasticity to make the cleaning cotton strip 96 contact with the surface of the transparent observation window 24. At this time, the cleaning cotton strip 96 can clean the transparent observation window 24. When the cleaning cotton strip 96 needs to be replaced, it is only necessary to push the push plate 98, and the push plate 98 will drive the rectangular plate 92 to move, and the rectangular plate 92 will drive the card plate 93 to move until the card plate 93 is completely separated from the inner wall of the rectangular groove 8. At this time, the cleaning shell 91 can be replaced. First, disassemble it from the inner wall of the through groove three 7. At this time, pull the cleaning cotton strip 96 to separate the magnetic plate 97 from the magnetic block 95. When installing, the cleaning cotton strip 96 and the magnetic block 95 can be magnetically connected together through the magnetism of the magnetic plate 97. At this time, put the cleaning shell 91 into the inner wall of the through groove three 7, and push the push plate 98 to make the rectangular plate 92 squeeze the spring two 94, and at the same time make the card plate 93 enter the interior of the cleaning shell 91 until the card plate 93 and the rectangular groove 8 are completely overlapped. At this time, loosen the push plate 98. The spring two 94 will push the rectangular plate 92 to move in the opposite direction through its own elasticity, and make the card plate 93 inserted into the inner wall of the rectangular groove 8, thus completing the installation.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
