Description

Technical Field

[0001] The utility model relates to the technical field of electrode sheet laser engraving, in particular to an electrode sheet laser engraving jig. Background Art

[0002] Laser engraving is a surface treatment process that uses the light energy of a laser beam to burn out patterns or text on the surface of a product. It mainly uses a high-energy-density laser beam to partially irradiate the surface of the material, causing physical or chemical changes on the surface of the material, thereby leaving a permanent mark.

[0003] In the laser engraving process, flexible fixtures or vacuum adsorption technology are generally used to ensure that the product can be stably and accurately placed in the processing position. However, these positioning technologies can only be applied to products of conventional shapes. For products with spherical surfaces, due to the complexity of the surface characteristics, flexible fixtures and vacuum adsorption technologies are difficult to effectively achieve accurate positioning. More importantly, due to the unevenness of the reference surface on which the product is placed, this will cause deviations when projecting the graphics onto the product surface, which in turn causes the problem of the processed product size exceeding the expected tolerance. Utility Model Content

[0004] Based on this, the utility model provides an electrode sheet laser engraving jig with a simple structure and easy use. A positioning cavity is provided on the top surface of the light-transmitting carrier plate. The supporting surface of the supporting table is matched with the outer surface of the electrode sheet, and the guide table is used for precise limiting to ensure that no deviation occurs during the processing. This dual positioning design not only improves the processing accuracy, but also greatly reduces the errors that may occur during the processing.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See also Figures 1 to 7 , is an electrode sheet laser engraving jig of an embodiment of the utility model, comprising a fixing plate 10, and a light-transmitting carrier plate 20 detachably mounted on the top surface of the fixing plate 10; the light-transmitting carrier plate 20 is used to position the electrode sheet 30. In this embodiment, the electrode sheet 30 is provided with a convex spherical surface facing the light-transmitting carrier plate 20.

[0027] The bottom surface of the fixing plate 10 is extended upward to form a receiving cavity 11, which is used to position and install a backlight source (not shown). The bottom surface of the fixing plate 10 is also provided with a wire groove 12 on one side corresponding to the receiving cavity 11, and the power cord of the backlight source is matched to pass through the wire groove 12.

[0028] A through hole 13 in a rectangular shape is provided in the middle of the fixed plate 10, and support platforms 14 protrude inward from the inner walls on the opposite sides of the fixed plate 10 corresponding to the through hole 13. The top surface height of the support platform 14 is smaller than the top surface height of the fixed plate 10. The height difference between the support platform 14 and the fixed plate 10 is utilized to position the light-transmitting supporting plate 20 and install it in the through hole 13, wherein the support platform 14 is used to abut against the light-transmitting supporting plate 20.

[0029] In this embodiment, an internal thread hole 15 is provided in the middle of the support platform 14 .

[0030] like Figures 4 to 6 As shown, the middle of the top surface of the light-transmitting carrier plate 20 is inwardly concavely provided with a positioning cavity 21 (such as Figure 6 The inner contour of the positioning cavity 21 corresponds to the outer contour of the electrode sheet 30. The light-transmitting carrier plate 20 is provided with guide platforms 22 at opposite ends corresponding to one side of the positioning cavity 21. The top of the guide platform 22 is provided with an inclined surface 220, and the bottom end of the inclined surface 220 faces the inside of the positioning cavity 21, so as to guide the electrode sheet 30 to slide into the positioning cavity 21.

[0031] A supporting platform 23 is convexly provided on one side of the light-transmitting carrier plate 20 corresponding to each guide platform 22, and the two supporting platforms 23 are arranged in a mirror image along the midline a of the positioning cavity 21. A supporting surface 230 is provided on the top of the supporting platform 23, and the supporting surface 230 is a concave spherical surface; the supporting surface 230 is used to match and fit the electrode sheet 30 to achieve the effect of positioning and supporting.

[0032] Furthermore, the supporting surfaces 230 of the two supporting platforms 23 are located on the same spherical surface, and the centers of the two supporting surfaces 230 coincide with the midline a of the positioning cavity 21 .

[0033] Since the supporting surface 230 is a concave spherical surface, and the side of the electrode sheet 30 facing the light-transmitting carrier plate 20 is a convex spherical surface, the two can be well matched and fit together. This design allows the center of gravity of the electrode sheet 30 to naturally slide onto the center line a of the positioning cavity 21 when the electrode sheet 30 is placed in the positioning cavity 21, thereby significantly enhancing the positioning effect of the electrode sheet 30 in the positioning cavity 21.

[0034] In actual work, the operator only needs to put the electrode sheet 30 into the positioning cavity 21. With the guidance of the inclined surface 220, the electrode sheet 30 will smoothly slide toward the two supporting platforms 23. As the electrode sheet 30 slides along the supporting surface 230, its center of gravity will naturally move to the center line a of the positioning cavity 21, thereby ensuring that the electrode sheet 30 is accurately positioned inside the positioning cavity 21. At this time, the arc edge of the electrode sheet 30 will contact the arc-shaped inner wall of the positioning cavity 21, and the straight edge of the electrode sheet 30 will contact the inner wall of the guide platform 22, which is equivalent to completely limiting the electrode sheet 30 inside the positioning cavity 21. This design further enhances the stability and positioning effect of the electrode sheet 30 in the positioning cavity 21, ensuring that no deviation will occur during the processing. This double positioning design not only improves the processing accuracy, but also greatly reduces the errors that may occur during the processing. Then, by using a high-brightness bulb as a backlight source, combined with a color filter and an optical system, the image of the electrode sheet 30 is projected onto the screen, so that the processing reference position of the electrode sheet 30 can be more accurately identified during processing. Figure 7 As shown, two circular gold dots 31 are retained on the top surface of the electrode sheet 30, and the other positions are removed by laser engraving. Thus, it is ensured that the gold dot positions can be accurately retained to meet the processing requirements.

[0035] In addition, considering the flexibility and tolerance of practical applications, a reserved gap of 0.02 mm is provided between the inner wall of the positioning cavity 21 and the outer contour of the electrode sheet 30. The existence of this tiny gap not only ensures that the electrode sheet 30 can be smoothly placed and positioned in the positioning cavity 21, but also provides room for error tolerance for tiny errors that may occur during its manufacturing and installation process.

[0036] In this embodiment, the light-transmitting carrier plate 20 is a white POM light-transmitting carrier plate having good light-transmitting performance.

[0037] In this embodiment, the light-transmitting carrier plate 20 is integrally formed, and its structure is decomposed for the convenience of description in this embodiment.

[0038] In this embodiment, through holes 24 are respectively provided on opposite sides of the light-transmitting carrier plate 20. The through holes 24 and the internal threaded holes 15 are respectively provided with bolts 25 passing through the through holes 24 and then screwed into the internal threaded holes 15, so that the installation between the light-transmitting carrier plate 20 and the fixing plate 10 can be achieved.

[0039] The above-mentioned electrode sheet laser engraving jig has a simple structure and is easy to use. A positioning cavity 21 is provided on the top surface of the transparent supporting plate 20. The supporting surface 230 of the supporting platform 23 is matched with the outer surface of the electrode sheet 30, and the guide platform 22 is used for precise limiting to ensure that the electrode sheet 30 will not be offset during the processing. This double positioning design not only improves the processing accuracy, but also greatly reduces the errors that may occur during the processing.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
