Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing, and in particular to a watch dial engraving device. Background Technology

[0002] In the watch manufacturing process, it is necessary to engrave words on the dial. Laser marking machines are usually used for this purpose. Laser marking machines use a high-energy laser beam to irradiate the surface of the material. By controlling the power and speed of the laser beam, marks of different depths and shapes can be made on the surface of various materials, such as text, numbers, patterns, and barcodes. It is widely used in the manufacturing of smartwatches.

[0003] For example, patent document CN222725730U discloses a watch dial engraving device with a dual-station feeding assembly. The operation of the second rotary cylinder can drive the fixed block and the connecting plate to rotate, thereby realizing the switching of two sets of watch dial fixtures through the operation of the second rotary cylinder. This facilitates the simultaneous unloading and loading of one set of watch dials while processing the other set, improving production efficiency. Furthermore, the watch dial fixtures are connected to the screw threadedly through the connecting block, allowing the watch dial fixtures to be assembled and disassembled, and thus replaced with watch dial fixtures of different sizes.

[0004] Although the above-mentioned device is equipped with a detachable dial fixture to accommodate dials of different sizes, it requires multiple sizes of dial fixtures for use. The dial fixtures themselves do not have the function of adjusting the size. A large number of dial fixtures require separate storage space, and it is necessary to search for the appropriate size when changing dial fixtures, which makes it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a watch dial engraving device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A watch dial engraving device includes a body, a laser marking mechanism mounted on the top of the body, a feeding mechanism on the top of the body, a feeding plate with two material slots, two V-shaped clamping plates inside the material slots, a transmission box fixed to the bottom of the feeding plate, a motor fixed to the top of the body, the output shaft of the motor fixedly connected to the transmission box, an elastic reset mechanism and a clamping and pushing mechanism inside the feeding plate, the elastic reset mechanism being fixedly connected to the clamping plate near the center of the feeding plate, the clamping and pushing mechanism being fixedly connected to the clamping plate away from the center of the feeding plate, a squeezing ring fixed to the top of the body for pushing the clamping and pushing mechanism to move, a transmission mechanism inside the transmission box for synchronously reversing the elastic reset mechanism and the clamping and pushing mechanism, and a through groove at the bottom of the feeding plate for avoiding the elastic reset mechanism and the clamping and pushing mechanism.

[0008] Preferably, the clamping and pushing mechanism includes a movable sleeve, which is slidably connected to one end of the feeding plate. One end of the movable sleeve extends into the material groove and is fixedly connected to a clamping plate. An adjusting screw is threaded into the movable sleeve, one end of which abuts against the inner wall of the extrusion ring. A second L-shaped rod is fixedly connected to the bottom of the movable sleeve, which passes through the through groove and extends into the transmission box.

[0009] Preferably, the elastic reset mechanism includes a movable rod that is slidably connected inside the feed plate. One end of the movable rod extends into the feed trough and is fixedly connected to a clamping plate. The other end of the movable rod is fixedly connected to a spring, which is located inside the feed plate. A first L-shaped rod is fixedly connected to the bottom of the movable rod. The first L-shaped rod passes through the through slot and extends into the transmission box.

[0010] Preferably, the transmission mechanism includes a first rack and a second rack arranged parallel to each other, the first rack being fixedly connected to a first L-shaped rod, the second rack being fixedly connected to a second L-shaped rod, and a gear meshing between the first rack and the second rack, the gear being rotatably installed inside the transmission box.

[0011] Preferably, the end of the adjusting screw near the extrusion ring is set to a hemispherical shape.

[0012] Preferably, the inner wall of the front end of the extrusion ring is provided with two left-right symmetrical inclined surfaces, and a release surface is provided between the two inclined surfaces in a smooth transition. The diameter of the release surface is larger than the diameter of the inner wall of the extrusion ring and smaller than the diameter of the outer wall of the extrusion ring.

[0013] The beneficial effects are as follows: The feeding plate is equipped with two material slots. The feeding plate is driven to rotate by a motor, realizing dual-station loading and unloading, ensuring processing efficiency. When the feeding plate rotates, the clamping and pushing mechanism and the extrusion ring squeeze each other, causing the clamping and pushing mechanism to drive one feeding plate to move. Through the transmission mechanism and the elastic reset mechanism, the other clamping plate moves, thereby clamping the dial. By adjusting the length of the clamping and pushing mechanism, the stroke of the clamping plate can be changed, thus adapting to dials of different sizes, making it more convenient to use.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6 As shown, a watch dial engraving device includes a body 1, a laser marking mechanism 2 mounted on the top of the body 1, and a feeding mechanism 4 on the top of the body 1. The feeding mechanism 4 includes a feeding plate 401 with two material slots 402, enabling dual-station loading and unloading. When one station is in processing position, the watch dial at the other station can be removed and a new watch dial to be processed can be placed in, thus improving processing efficiency. Two V-shaped clamping plates 5 are provided in the material slots 402, which can stably clamp watch dials of different diameters. A transmission box 403 is fixed to the bottom of the feeding plate 401, and a motor 3 is fixed to the top of the body 1. The output shaft of the motor 3 is connected to the transmission box 403. The machine body 1 is fixedly connected to a transmission box 403 and a feeding plate 401, which are driven by a motor 3 to rotate, thus realizing the interchange of two workstations. The feeding plate 401 is equipped with an elastic reset mechanism 6 and a clamping and pushing mechanism 7. The elastic reset mechanism 6 is fixedly connected to a clamping plate 5 on the side close to the center of the feeding plate 401, and the clamping and pushing mechanism 7 is fixedly connected to a clamping plate 5 on the side away from the center of the feeding plate 401. The top of the machine body 1 is fixed with a squeezing ring 9 for squeezing and pushing the clamping and pushing mechanism 7 to move. The transmission box 403 is equipped with a transmission mechanism 8 for making the elastic reset mechanism 6 and the clamping and pushing mechanism 7 move synchronously in opposite directions. The bottom of the feeding plate 401 is provided with a through groove 404 for avoiding the elastic reset mechanism 6 and the clamping and pushing mechanism 7.

[0027] The clamping and pushing mechanism 7 includes a movable sleeve 701, which is slidably connected to one end of the feeding plate 401. One end of the movable sleeve 701 extends into the material groove 402 and is connected to a clamping plate 5 by screws. An adjusting screw 702 is threadedly connected to the movable sleeve 701. One end of the adjusting screw 702 abuts against the inner wall of the extrusion ring 9. A second L-shaped rod 703 is fixedly connected to the bottom of the movable sleeve 701. The second L-shaped rod 703 passes through the through groove 404 and extends into the transmission box 403.

[0028] The inner wall of the front end of the extrusion ring 9 is provided with two symmetrical inclined surfaces 901. A release surface 902 is smoothly transitioned between the two inclined surfaces 901. The diameter of the release surface 902 is larger than the diameter of the inner wall of the extrusion ring 9 and smaller than the diameter of the outer wall of the extrusion ring 9. The initial state is when the adjusting screw 702 is in contact with the release surface 902. When the feeding plate 401 rotates, it drives the adjusting screw 702 to make a circular motion. When the adjusting screw 702 moves from the release surface 902 to the inclined surface 901, the adjusting screw 702 is squeezed and drives the movable sleeve 701 to move. The movable sleeve 701 drives the clamping plate 5 to move. By rotating the adjusting screw 702... 2. This allows the adjustable screw 702 to extend and retract within the movable sleeve 701, thereby changing the overall length of the movable sleeve 701 and the adjusting screw 702. For example, when the overall length of the movable sleeve 701 and the adjusting screw 702 increases, initially, the clamping plate 5 will be closer to the center of the material trough 402, thus enabling the clamping of smaller dials. Conversely, when the overall length of the movable sleeve 701 and the adjusting screw 702 decreases, it can clamp larger dials. Therefore, by simply rotating the adjusting screw 702 to adjust the overall length of the movable sleeve 701 and the adjusting screw 702, different sized dials can be accommodated, making it more convenient to use. The end of the adjusting screw 702 near the extrusion ring 9 is set in a hemispherical shape to reduce the friction between the adjusting screw 702 and the extrusion ring 9, making the movement of the adjusting screw 702 smoother.

[0029] The elastic reset mechanism 6 includes a movable rod 601, which is slidably connected inside the feed plate 401. One end of the movable rod 601 extends into the feed trough 402 and is fixedly connected to a clamping plate 5. The other end of the movable rod 601 is fixedly connected to a spring 602, which is located inside the feed plate 401. The spring 602 is always in a stretched state, that is, the spring 602 always applies a pulling force to the movable rod 601. This pulling force has the function of driving the movable rod 601 to move towards the center of the feed plate 401. A first L-shaped rod 603 is fixedly connected to the bottom of the movable rod 601. The first L-shaped rod 603 passes through the through groove 404 and extends into the transmission box 403.

[0030] The transmission mechanism 8 includes a first rack 801 and a second rack 802 arranged in parallel. The first rack 801 is fixedly connected to the first L-shaped rod 603, and the second rack 802 is fixedly connected to the second L-shaped rod 703. A gear 803 meshes between the first rack 801 and the second rack 802, and the gear 803 is rotatably installed inside the transmission box 403.

[0031] Working principle: In use, the dial to be processed is placed in the front material trough 402. The motor 3 drives the transmission box 403 and the feeding plate 401 to rotate. The feeding plate 401 drives the adjusting screw 702 to make a circular motion. The adjusting screw 702 moves from the release surface 902 to the inclined surface 901. During the movement of the adjusting screw 702 on the inclined surface 901, the adjusting screw 702 is squeezed and drives the movable sleeve 701 to move. The movable sleeve 701 drives the clamping plate 5 and the second L-shaped rod 703 to move. The second L-shaped rod 703 drives the second rack 802 to move. The second rack 802 drives the gear 803 to rotate. The gear 803 drives the first rack 801 to move. The first rack 801 drives the first… The L-shaped rod 603 moves, causing the movable rod 601 to move. The movable rod 601 then moves the other clamping plate 5, bringing the two clamping plates 5 closer together to hold the dial. When the dial moves below the laser marking mechanism 2, laser marking begins. After processing, the loading plate 401 rotates again. As the adjusting screw 702 moves from the inclined plane 901 to the release surface 902, the spring 602 rebounds and pulls the movable rod 601 back to its original position. Through the transmission of the first rack 801, the second rack 802, and the gear 803, the second L-shaped rod 703 drives the movable sleeve 701 back to its original position. The two clamping plates 5 then release the processed dial, which can then be removed.

[0032] When processing dials of different sizes, the adjusting screw 702 is rotated to extend and retract within the movable sleeve 701, thereby changing the overall length of the movable sleeve 701 and the adjusting screw 702. For example, when the overall length of the movable sleeve 701 and the adjusting screw 702 increases, the clamping plate 5 will be closer to the center of the material groove 402 in the initial state, thus enabling the clamping of smaller dials. Conversely, when the overall length of the movable sleeve 701 and the adjusting screw 702 decreases, it can clamp larger dials. Therefore, by simply rotating the adjusting screw 702 to adjust the overall length of the movable sleeve 701 and the adjusting screw 702, different sizes of dials can be accommodated, making it more convenient to use.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
