Description

Technical Field

[0001] The utility model belongs to the technical field of crystal processing and relates to a special-shaped crystal printing fixture. Background Art

[0002] Due to their beauty and unique optical effects, crystal and glass materials are increasingly widely used in automotive parts. In order to improve product consistency and efficiency, special printing fixtures are used in the processing of crystal and glass automotive products.

[0003] In the processing of crystal and glass automotive products, since there are cumulative tolerances in the processing and manufacturing of both products and printing fixtures, how to ensure that the products are firmly positioned on the printing fixture is an issue that must be solved. However, the existing printing fixtures have the problems of complex structure and high cost.

[0004] For this reason, Chinese Patent Application (Application No.: 201420787837.0) discloses an automatic positioning and bearing fixture for glass printing, including a fixture body. A glass printing bearing cavity for placing printing products is provided on the fixture body, and vacuum suction holes for adsorbing and fixing the printing products are provided in the glass printing bearing cavity. A first pick-and-place groove for picking and placing printing products is also provided on the fixture body, and the first pick-and-place groove communicates with the glass printing bearing cavity. A positioning adjustment groove and a positioning spring are also provided on the fixture body. The positioning adjustment groove is located outside the glass printing bearing cavity. A positioning movable block is located in the positioning adjustment groove and presses against the outside of the printing product. The positioning movable block includes a first positioning movable block in the X-axis direction and a second positioning movable block in the Y-axis direction. The positioning spring presses between the first positioning movable block and the fixture body, and the positioning spring presses between the second positioning movable block and the fixture body.

[0005] However, the above method has the following defects: 1. There are many styles of crystal and glass automotive products, and different products have different thicknesses. In this fixture, the printing bearing cavity, the first pick-and-place groove, and the positioning adjustment groove are all provided on the fixture body, that is, the thickness of the products that can be carried is fixed. If different styles of products need to be processed, the entire fixture needs to be redesigned, with poor applicability and high cost. 2. There are many styles of crystal and glass automotive products, and some products have irregular shapes. In this fixture, the first positioning movable block and the second positioning movable block clamp and fix the product under the action of the spring. The shapes of the first positioning movable block and the second positioning movable block are fixed. If an irregular-shaped product is encountered, the first positioning movable block and the second positioning movable block may only contact part of the surface of the product, affecting the stable and reliable fixation of the product, with poor applicability. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the above problems in the existing technology and propose a special-shaped crystal printing jig. The technical problem to be solved by the utility model is: how to improve the applicability of the printing jig and reduce the cost.

[0007] The purpose of the utility model can be achieved through the following technical solutions: a special-shaped crystal printing jig, including a jig body, the upper surface of the jig body is provided with a connecting installation groove and a clearance groove, characterized in that a positioning plate is embedded in the installation groove, the positioning plate is abutted against the groove wall of the installation groove and a clearance space is formed between the groove wall of the clearance groove, and the upper surface of the positioning plate is provided with a positioning groove for the crystal product to be embedded.

[0008] The crystal product is embedded in the positioning groove, and the product surface is against the positioning groove wall to achieve product positioning. When the positioning plate is embedded in the installation groove, the positioning plate is against the installation groove wall and a clearance space is formed between the positioning plate and the groove wall of the clearance groove. The installation groove limits the rotation and movement of the positioning plate in the circumferential direction, and the clearance groove leaves operating space for the staff to take and put the positioning plate. The installation groove plays a positioning role for the positioning plate, and the positioning plate plays a positioning role for the product. For products of different thicknesses and different shapes and contours, targeted matching positioning grooves are engraved to make the shape of the positioning groove fit the shape of the corresponding product, so that regular or irregular shaped products can be stably and reliably embedded in the positioning groove to achieve reliable and stable positioning of the product. The positioning plate can be flexibly replaced on the same fixture body to meet the processing needs of different styles of products, and then the mother-and-child sets are uniformly used on one machine for printing, which improves applicability and reduces costs. The clearance groove provides sufficient space for the staff to take and put the positioning plate, which is conducive to ensuring stable and reliable pick-and-place operations, improving the convenience and safety of operations, and improving production efficiency.

[0009] The above-mentioned special-shaped crystal printing jig has two clearance grooves, which are respectively located on opposite sides of the installation groove. The clearance grooves are located on both sides of the installation groove, that is, when the positioning plate is placed in the installation groove, the clearance space formed between the positioning plate and the groove wall of the clearance groove is located on both sides of the positioning plate. When the staff takes and places the positioning plate, the positioning plate is evenly stressed, which reduces the risk of deformation or accidental falling caused by uneven stress on the positioning plate during the taking and placing process, prolongs the service life of the positioning plate, and ensures the convenience, stability and reliability of the operation of replacing the positioning plate.

[0010] In the above-mentioned special-shaped crystal printing jig, the said clearance groove is a square groove. The processing of the square groove is relatively easy, and it can usually be realized by common processes such as milling and laser cutting. The geometric shape of the square groove makes it easier to clean the inside, providing sufficient space for the staff to take and place the positioning plate, while reducing the production and maintenance costs.

[0011] For the above-mentioned special-shaped crystal printing fixture, the positioning plate is a square plate, and the shape of the cross-section of the installation groove is adapted to the shape of the cross-section of the positioning plate. The positioning plate being a square plate with a regular shape can be stacked very conveniently, saving vertical space. By stacking multiple square plates together, staff can achieve more efficient storage without occupying too much lateral space. The shape of the cross-section of the installation groove is adapted to the shape of the cross-section of the positioning plate, that is, the installation groove is a square groove. The shape of the square groove provides a larger contact surface, which can effectively disperse the force applied to the positioning plate, thereby enhancing the stability of the positioning plate. In addition, the square groove is easier to identify visually. For operators, it can quickly determine whether the positioning plate is placed in place, reducing the possibility of operation errors and further improving the convenience of operation.

[0012] For the above-mentioned special-shaped crystal printing fixture, the four corners of the positioning plate are chamfered. The chamfer design can prevent staff from being scratched by sharp edges when picking up and placing the positioning plate.

[0013] For the above-mentioned special-shaped crystal printing fixture, there is a smooth transition between the groove wall of the installation groove and the groove wall of the relief groove. The smooth transition design can eliminate the sharp edges between the groove wall of the installation groove and the groove wall of the relief groove, reducing the risk of staff being scratched during operation. In addition, the smooth transition design can reduce the friction during the picking up and placing of the positioning plate, reduce the degree of wear, extend the service life of the positioning plate and the fixture body, and reduce the maintenance and replacement costs.

[0014] For the above-mentioned special-shaped crystal printing fixture, the depth of the installation groove is the same as the depth of the relief groove. The unified depth design simplifies the manufacturing process of the fixture, makes the processing process more convenient, and reduces the production cost.

[0015] Compared with the prior art, the present special-shaped crystal printing fixture has the following advantages:

[0016] 1. In the present special-shaped crystal printing fixture, the installation groove positions the positioning plate, and the positioning plate positions the product. For products with different thicknesses and different shape profiles, targeted engraved matching positioning grooves are made so that the shape of the positioning groove fits the shape of the corresponding product, enabling products with regular or special shapes to be stably and reliably embedded in the positioning groove, realizing reliable and stable positioning of the product.

[0017] 2. In the present special-shaped crystal printing fixture, the positioning plate can be flexibly replaced on the same fixture body to adapt to the processing requirements of different styles of products, and then the mother and son sets are uniformly used for printing on a machine table, improving the applicability and reducing the cost.

[0018] 3. In this special-shaped crystal printing fixture, the relief groove provides sufficient space for the operator to pick up and place the positioning plate, which helps ensure the stability and reliability of the picking and placing operations, improves the convenience and safety of the operations, and enhances the production efficiency.

[0027] There are two relief grooves 3, which are respectively located on both sides of the installation groove 2. Specifically, the relief grooves 3 are symmetrical about the installation groove 2. The relief grooves 3 are located on both sides of the installation groove 2 and are symmetrical about the installation groove 2. That is, when the positioning plate 4 is placed in the installation groove 2, the relief space formed between the positioning plate 4 and the groove wall of the relief groove 3 is located on both sides of the positioning plate 4 and is symmetrical about the installation groove 2. When the staff takes and places the positioning plate 4, the positioning plate 4 is evenly stressed, reducing the risk of deformation or accidental dropping caused by uneven stress on the positioning plate 4 during the taking and placing process, extending the service life of the positioning plate 4, and ensuring the convenience, stability and reliability of the operation of replacing the positioning plate 4.

[0028] The relief groove 3 is a square groove, and the positioning plate 4 is a square plate. The shape of the cross-section of the installation groove 2 is adapted to the shape of the cross-section of the positioning plate 4, that is, the installation groove 2 is a square groove. The processing of square grooves is relatively easy and can usually be achieved through common processes such as milling and laser cutting. Moreover, the geometric shape of the square groove makes it easier to clean inside, providing enough space for the staff to operate when taking and placing the positioning plate 4, while reducing production and maintenance costs. The positioning plate 4 is a square plate with a regular shape and can be easily stacked, saving vertical space. By stacking multiple square plates together, users can achieve more efficient storage without occupying too much horizontal space. The installation groove 2 is designed as a square, providing a larger contact surface, which can effectively disperse the force applied to the positioning plate 4, thereby enhancing the stability of the positioning plate 4. In addition, the square groove is easier to identify visually. For operators, it can quickly judge whether the positioning plate 4 is placed in place, reducing the possibility of operation errors and further improving the convenience of operation.

[0029] The four corners of the positioning plate 4 are chamfered, and there is a smooth transition between the groove wall of the installation groove 2 and the groove wall of the relief groove 3. The chamfer design can prevent the staff from being scratched by sharp edges when taking and placing the positioning plate 4. The smooth transition design can eliminate the sharp edges between the groove wall of the installation groove 2 and the groove wall of the relief groove 3, reducing the risk of the staff being scratched during the operation. In addition, the smooth transition design can reduce the friction during the taking and placing of the positioning plate 4, reduce the degree of wear, extend the service life of the positioning plate 4 and the jig body 1, and reduce the maintenance and replacement costs.

[0030] The depth of the installation groove 2 is the same as the depth of the relief groove 3. The unified depth design simplifies the manufacturing process of the jig, makes the processing process simpler, and reduces the production cost.

[0031] The crystal product is embedded in the positioning groove 5, and the surface of the product abuts against the groove wall of the positioning groove 5 to realize the positioning of the product. When the positioning plate 4 is embedded in the installation groove 2, the positioning plate 4 abuts against the groove wall of the installation groove 2 and forms a relief space with the groove wall of the relief groove 3. The installation groove 2 circumferentially restricts the rotation and movement of the positioning plate 4, while the relief groove 3 leaves an operating space for the staff to take and place the positioning plate 4.

[0032] The mounting groove 2 positions the positioning plate 4, and the positioning plate 4 positions the product. For products of different thicknesses and different shapes and contours, matching positioning grooves 5 are specifically engraved to make the shape of the positioning groove 5 match the shape of the corresponding product, so that products with regular or irregular shapes can be stably and reliably embedded in the positioning groove 5, achieving reliable and stable positioning of the product. The positioning plate 4 can be flexibly replaced on the same jig body 1 to meet the processing needs of products of different styles. The positioning plate 4 and the jig body 1 form a mother-and-child set, which can be used for machine printing on one machine. The installation and disassembly process is relatively simple, which is convenient for maintenance and replacement, and reduces costs. The clearance groove 3 provides sufficient space for the staff to operate the positioning plate 4, which is conducive to ensuring the stable and reliable operation of the pick-and-place operation, improving the convenience and safety of the operation, and improving production efficiency.
