Description

Technical Field

[0001] This utility model belongs to the field of laser engraving technology, specifically relating to an automatic laser focus adjustment device for laser engraving watch cases. Background Technology

[0002] Laser engraving machines, also known as laser marking machines or laser engraving machines, are devices that use a laser beam to engrave permanent marks on the surface of materials or inside transparent materials. Their working principle is based on the chemical and physical effects of laser light on matter. When a material absorbs the laser light instantaneously, a physical or chemical reaction occurs, thus engraving marks, patterns, or text on the surface. In the watchmaking industry, the watch case, as a core exterior component, directly determines the product's visual quality and market competitiveness through the precision and consistency of the laser-engraved patterns (such as brand logos, model markings, and decorative patterns).

[0003] The existing technology includes a laser engraving machine with patent publication number CN221516516U that can quickly prevent displacement. This patent uses rollers to facilitate movement of the laser engraving machine, causing the positioning plate to move downwards and move the connected anti-slip pads to the ground. This suspends the rollers connected to the machine housing from the ground, fixing the machine housing in the moving position, thus achieving both movement and rapid automatic fixation to prevent displacement. However, in practical use, it still has the following shortcomings: In practice, when using this laser engraving machine, the product is placed directly on the placement plate, requiring manual adjustment of the product's position so that the laser engraving machine can label the designated location. Manual operation is slow and lacks precision. Furthermore, since the wire and plastic materials may contain additives, pigments, or other chemical components, when the laser beam engraves labels on these products, some additives or pigments may decompose due to heat, generating waste gas that could harm human health and the environment.

[0004] Therefore, there is a need for an automatic laser focus adjustment device for laser engraving watch cases, which solves the problems of needing to manually adjust the position of the product and generating exhaust gas when the laser beam engraves labels on these products in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic laser focus adjustment device for laser engraving on watch cases, comprising a body, a laser engraving head, a clamping mechanism, a display screen, and a gas collection mechanism. The laser engraving head is disposed above the body, the clamping mechanism is disposed below the laser engraving head, the display screen is disposed on the upper right side of the body, and the gas collection mechanism is disposed on both sides of the clamping mechanism.

[0007] It should be noted in the solution that the clamping mechanism consists of a mounting frame, buttons, connecting lines, a fixed shaft, a rotating disk, a rotating rod, a connecting block, a moving block, a clamping block, an electric push rod, and a placement plate. The mounting frame is fixedly connected to the top of the machine body, the buttons are symmetrically fixedly connected to the front of the mounting frame, the connecting lines are located inside the mounting frame, and the placement plate is fixedly connected to the upper center of the mounting frame.

[0009] Furthermore, it should be noted that the top plate of the mounting frame is symmetrically provided with cross grooves that are adapted to the moving block, and the clamping block is provided with an anti-slip layer on the side near the center of the support plate.

[0010] In a preferred embodiment, the electric push rod is fixedly connected to the inside right side of the connecting line, and the two ends of the connecting line are respectively connected to the button and the electric push rod. The extended end of the electric push rod is fixedly connected to the bottom surface of the right-side moving block.

[0011] In a preferred embodiment, the gas collection mechanism comprises an air pump, a collection box, an air delivery pipe, an adjustable pipe, a gas collection head, a fixing block, a fixing cylinder, a telescopic column, a threaded rod, and a top block.

[0013] In a preferred embodiment, the top block is rotatably connected to the side of the threaded rod near the telescopic column, and the other end of the threaded rod is fixedly connected to a turntable.

At the same time, the negative pressure generated by the air pump can collect the waste gas generated during the engraving process, filter it and then discharge it to effectively avoid air pollution.

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides an automatic laser focus adjustment device for laser engraving on watch cases, including a body 1, a laser head 2, a clamping mechanism 3, a display screen 4, and a gas collection mechanism 5. The laser head 2 is located above the body 1, the clamping mechanism 3 is located below the laser head 2, the display screen 4 is located on the upper right side of the body 1, and the gas collection mechanism 5 is located on both sides of the clamping mechanism 3.

[0025] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the clamping mechanism 3 consists of a mounting frame 301, a button 302, a connecting line 303, a fixed shaft 304, a rotating disk 305, a rotating rod 306, a connecting block 307, a moving block 308, a clamping block 309, an electric push rod 310, and a placement plate 311. The mounting frame 301 is fixedly connected to the top of the machine body 1. The button 302 is symmetrically fixedly connected to the front of the mounting frame 301. The connecting line 303 is located inside the mounting frame 301. The placement plate 311 is fixedly connected to the upper center of the mounting frame 301.

[0026] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the fixed shaft 304 is fixedly connected to the inside of the mounting frame 301, the rotating disk 305 is rotatably connected to the outside of the fixed shaft 304, the rotating rod 306 is symmetrically rotatably connected to the lower periphery of the rotating disk 305, the connecting block 307 is rotatably connected to the other end of the rotating rod 306, the moving block 308 is fixedly connected to one side of the connecting block 307, the clamping block 309 is fixedly connected to the top of the moving block 308, the top plate of the mounting frame 301 is symmetrically provided with cross grooves that are adapted to the moving block 308, and the clamping block 309 is provided with an anti-slip layer on the side near the center of the support plate.

[0027] The anti-slip layer on the clamp 309 contacts the dial, achieving stable clamping of dials of different sizes and improving clamping stability.

[0028] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the electric push rod 310 is fixedly connected to the inside right side of the connecting line 303. The two ends of the connecting line 303 are respectively connected to the button 302 and the electric push rod 310. The extended end of the electric push rod 310 is fixedly connected to the bottom surface of the right moving block 308.

[0029] Pressing button 304 controls the start and stop of the electric push rod 310, thereby controlling the movement distance of the clamping block 309, thus clamping dials of different sizes and improving the convenience of control.

[0030] As can be seen from the above working process: by pressing the button 302, the four clamping blocks 309 can be driven to move synchronously in opposite directions through the clamping mechanism 3. With the anti-slip layer on the inner side of the clamping block 309, a uniform wrapping clamping can be formed on watch cases of different sizes, effectively avoiding the problem of watch case displacement in traditional manual clamping. At the same time, the cross groove on the top plate of the mounting frame 301 provides precise guidance for the moving block 308, further ensuring the positioning accuracy of the clamping block 309, so that the watch case is always directly below the laser head, ensuring the stability of the focal position.

[0031] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the air collection mechanism 5 consists of an air pump 501, a collection box 502, an air delivery pipe 503, an adjustable pipe 504, an air collection head 505, a fixing block 506, a fixing cylinder 507, a telescopic column 508, a threaded rod 509, and a top block 510. The air pump 501 is fixedly connected to the upper back of the body 1. The collection box 502 is located at the output end of the air pump 501. The air delivery pipe 503 is connected to the input end of the air pump 501. The adjustable pipe 504 is symmetrically arranged at both ends of the air delivery pipe 503. The air collection head 505 is fixedly connected to the end of the adjustable pipe 504. The fixing block 506 is located between the air delivery pipe 503 and the adjustable pipe 504.

[0032] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the fixed cylinder 507 is fixedly connected to the top of the machine body 1, the telescopic column 508 is slidably connected to the inside of the fixed cylinder 507, the fixed block 506 is fixedly connected to the telescopic column 508, and the threaded rod 509 is threadedly connected to the front of the fixed cylinder 507, and the threaded rod 509 extends into the inside of the fixed cylinder 507.

[0033] The adjustable tube 504 allows for fine-tuning of the angle of the gas collecting head 505, which improves the collection of exhaust gas and enhances the performance of the mechanism.

[0034] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the top block 510 is rotatably connected to the threaded rod 509 on the side near the telescopic column 508, and the other end of the threaded rod 509 is fixedly connected to a turntable.

[0035] The turntable drives the threaded rod 509 to rotate, causing the top block 510 to fit tightly against the outer surface of the telescopic column 508, which can fix the position of the telescopic column 508 and facilitate operation by the user.

[0036] The solution has the following working process: When in use, the watch case to be engraved is placed on the placement plate 311. The electric push rod 310 is started by controlling the button 304. The extended end of the electric push rod 310 pushes the right moving block 308 to move in the cross groove inside the support plate. Due to the rotational connection between the rotating disk 305, the rotating rod 306, and the connecting block 307, the rotating disk 305 is driven to rotate, thereby driving the other three rotating rods 306 to rotate, which in turn drives the moving block 308 and the clamping block 309 to move, so that the four clamping blocks 309 move towards each other. The anti-slip layer on the clamping block 309 contacts the watch dial, realizing stable clamping of watch dials of different sizes, so that the watch dial is stably placed under the laser head 2.

[0037] Then, the telescopic column 508 is moved inside the fixed cylinder 507 to control the height of the gas collecting head 505, so that it can absorb the waste gas of the engraved product. The turntable is rotated, and the top block 510 is moved towards the telescopic column 508 through the threaded rod 509, so that the surface of the telescopic column 508 is fixed to abut, thus completing the adjustment of the height of the gas collecting head 505. Finally, the laser head 2 is controlled to engrave the product. At the same time as engraving, the air pump 501 is started, and the generated gas is collected in sequence through the gas collecting head 505, the adjustable pipe 504 and the air supply pipe 503 into the collection box 502 for gas filtration to avoid direct emission and air pollution.

[0038] In summary: The clamping mechanism 3 allows four clamping blocks 309 to move synchronously in opposite directions when the button 302 is pressed. Combined with the anti-slip layer on the inner side of the clamping blocks 309, this provides a uniform, enveloping clamping effect on watch cases of different sizes, effectively avoiding the watch case shifting problem encountered in traditional manual clamping. Simultaneously, the cross groove on the top plate of the mounting frame 301 provides precise guidance for the moving block 308, further ensuring the positioning accuracy of the clamping blocks 309 and keeping the watch case always directly below the laser head, guaranteeing a stable focal position. The gas collection mechanism 5 allows for flexible adjustment of the gas collection head 505's posture according to the watch case size and engraving position, ensuring that the distance between the gas collection head 505 and the engraving area remains within the optimal absorption range. Furthermore, the negative pressure generated by the air pump 501 collects the waste gas produced during the engraving process, filters it, and then releases it, effectively preventing air pollution.
