Description

Technical Field

[0001] The utility model relates to the technical field of mold etching, in particular to an etching mold component with accurate positioning. Background Art

[0002] Etching is a technique that uses chemical reactions or physical impact to remove part of a material. Etching technology can be divided into two categories: wet etching and dry etching. It was first used to make printing embossed plates such as copper plates and zinc plates. It is also widely used to reduce the weight of instrument panels, nameplates, and thin workpieces that are difficult to process with traditional processing methods. After continuous improvement and development of process equipment, it can also be used for the processing of precision etching products of electronic thin-film parts in the aviation, machinery, and chemical industries. Especially in the semiconductor process, etching is an indispensable technology.

[0003] In the mold etching process, a laser transmitter is required to first laser engrave the mold surface, so the fixed positioning of the mold is also particularly important. Traditional positioning devices are generally directly fixed, and their accuracy is mainly determined by the scale lines on the surface. For example, the patent with publication number CN218694971U discloses an etching mold assembly with precise positioning, which can quickly adjust the positions of the first clamping plate and the second clamping plate according to the position where the mold needs to be etched. The position of the first clamping plate can be accurately adjusted by the matching setting of the first scale value and the first pointer, and the position of the second clamping plate can be accurately adjusted by the matching setting of the second scale value and the second pointer. The mold can be quickly and accurately positioned, making the positioning of the mold relatively simple, and achieving the effect of improving the processing efficiency. However, there is a positioning error by using the matching between the scale lines and the pointer, and the laser transmitter is located above the fixed mold. It is impossible to ensure that the position to be engraved and the laser transmitter are kept on the same vertical line in the vertical direction, resulting in the position to be laser engraved cannot be accurately determined at the bottom of the laser transmitter, which is inconvenient for actual use.

After accurate positioning, the mounting block 4 is rotated 180 degrees by using the adjustment mechanism, so that the laser emitter 7 faces directly downward, and the laser pen 8 and the laser emitter 7 are located on the same straight line. Therefore, after rotating 180 degrees, the laser emitter 7 can be exactly aligned with the point that needs to be laser engraved. In the process of engraving with the laser emitter 7, the mold body 12 can be driven to move by using the first driving mechanism and the second driving mechanism again, so that different positions of the mold body 12 can be located at the bottom end of the laser generator to process different shapes.

[0028] Furthermore, the fixing mechanism includes two clamping blocks 13, and a sliding groove is provided on the surface of the connecting plate 16. The two clamping blocks 13 are slidably connected inside the sliding groove. The inside of the sliding groove is rotatably connected with a first screw 14.

A rack 9 is fixedly installed on the output port of the cylinder 11, and a gear 6 is fixedly installed on the surface of the rotating shaft 5. The rack 9 and the gear 6 are meshed. When the adjusting mechanism is in use, the cylinder 11 is started, and the cylinder 11 drives the rack 9 to move, so that the rack 9 drives the gear 6 to rotate, and then the gear 6 drives the rotating shaft 5 to rotate on the connecting frame 2, so that the rotating shaft 5 drives the mounting block 4 to rotate, and then the mounting block 4 can drive the laser pen 8 and the laser emitter 7 to flip 180 degrees, so that the laser pen 8 and the laser emitter 7 are always in the same straight line in the vertical direction, the position will not be offset, and can be accurately positioned.

[0030] Furthermore, a long plate 10 is fixedly mounted on the side wall of the rack 9, and the long plate 10 is slidably connected to the long groove 3. By providing the long plate 10 to support the rack 9, the rack 9 is more stable when moving, which is convenient for actual operation.

[0031] In summary, when in use, firstly, the mold body 12 is fixed on the surface of the placement plate 19 by using the fixing mechanism, the laser pen 8 is turned on, so that the laser point projected by the laser pen 8 can be located on the mold body 12, and the mold body 12 is driven to move forward and backward and left and right by using the first driving mechanism and the second driving mechanism, so that the position of the mold body 12 that needs to be laser engraved is moved to the laser point projected by the laser pen 8, and the laser point irradiation method is used to determine the position that needs to be laser engraved, so as to improve its accuracy. After accurate positioning, the mounting block 4 is rotated 180 degrees by using the adjustment mechanism, so that the laser emitter 7 faces directly downward, and the laser pen 8 and the laser emitter 7 are located on the same straight line, so that the laser emitter 7 rotates After turning 180 degrees, it can be just aligned with the point that needs laser engraving. In the process of engraving with the laser emitter 7, the first driving mechanism and the second driving mechanism can be used again to drive the mold body 12 to move, so that different positions of the mold body 12 can be located at the bottom of the laser generator to process different shapes.

The laser emitter 7 and the laser pen 8 are on the same vertical line, and the position will not be offset. Accurate engraving can be achieved, which improves the accuracy of etching and facilitates actual operation. When the first driving mechanism is in use, the third motor 20 is started. The third motor 20 drives the third screw 21 to rotate, and the rotation of the third screw 21 drives the placement plate 19 to move forward and backward, so that the placement plate 19 drives the second driving mechanism and the mold body 12 to move forward and backward, which is convenient for practical use and improves the accuracy of etching. When the second driving mechanism is in use, the second motor 18 is started, and the second motor 18 drives the second screw 17 to rotate. The rotation of the second screw 17 drives the connecting plate 16 to slide left and right. The sliding of the connecting plate 16 to the left and right drives the placement plate 19 to move left and right, and then the placement plate 19 drives the mold body 12 to move left and right. When the fixing mechanism is in use, the first motor 15 is started, and the first motor 15 drives the first screw 14 to rotate. The rotation of the first screw 14 drives the two clamping blocks 13 to move closer to each other. Thereby, the clamping block 13 clamps and fixes the mold body 12 on the surface of the placement plate 19, so that the position of the placement plate 19 will not shift during etching, making the etching more accurate. When the adjustment mechanism is in use, the cylinder 11 is started, and the cylinder 11 drives the rack 9 to move, so that the rack 9 drives the gear 6 to rotate, and then the gear 6 drives the rotating shaft 5 to rotate on the connecting frame 2, so that the rotating shaft 5 drives the mounting block 4 to rotate, and then the mounting block 4 can drive the laser pen 8 and the laser emitter 7 to flip 180 degrees, so that the laser pen 8 and the laser emitter 7 are always in the same straight line in the vertical direction, the position will not shift, and can be accurately positioned.
