Description

Technical Field

[0001] This application relates to the field of semiconductor equipment technology, and more specifically, to a positioning fixture and engraving equipment. Background Technology

[0002] With the rapid development of the semiconductor industry, substrates are generally marked with lasers to identify components. Laser marking is a surface treatment process based on optical principles. To ensure printing accuracy, a laser marking positioning fixture is required. However, in practice, the heat generated by laser printing can easily cause the substrate to collapse and deform; simultaneously, dust generated during printing can adhere to the printing platform, causing contamination of the back side of the substrate during subsequent printing. All of these problems can adversely affect the subsequent ball-mounting process. Utility Model Content

[0003] The purpose of this application is to provide a positioning fixture and engraving equipment. By cooperating with a support platform and at least two fixing parts, the workpiece to be printed can be stably fixed to ensure positioning accuracy and avoid collapse and deformation of the workpiece. At the same time, the groove can directly accommodate the debris generated when the workpiece is engraved, so as to avoid the debris contaminating the workpiece and the platform, thereby ensuring the quality of subsequent processing.

[0004] The embodiments of this application are implemented as follows: A first aspect of this application provides a positioning fixture, including a base and at least two fixing members disposed on the base. The base has a groove located between the at least two fixing members along the line connecting them. A support platform is disposed within the groove. The support platform supports a workpiece to be printed and clamps the workpiece with the cooperation of the at least two fixing members, while the groove accommodates debris generated during the engraving process. This positioning fixture, through the cooperation of the support platform and the at least two fixing members, can stably fix the workpiece to ensure positioning accuracy, preventing collapse and deformation, and can also directly accommodate debris generated during engraving, preventing debris from contaminating the workpiece and the platform, thereby ensuring the quality of subsequent processing.

[0005] As one possible implementation, it also includes a connector, wherein the sidewall of the groove is provided with a mounting hole, each of the fixing members is provided with a connecting hole, and the connector passes through the connecting hole and the mounting hole so that the fixing member is assembled on the base.

[0006] As one possible implementation, a locking nut is also included. The outer wall of the connector is provided with threads, and the connecting hole is a strip-shaped hole. The locking nut is used to engage with the connector thread to lock the fixing member at any position within the strip-shaped hole.

[0007] As one possible implementation, a locking nut is also included. The outer wall of the connector is provided with threads, and there are multiple connecting holes. The multiple connecting holes are distributed at intervals along the line connecting the at least two fixing members. The locking nut is used to engage with the connecting member threadedly to lock the fixing member in any one of the connecting holes.

[0008] In one possible implementation, the fastener is a U-shaped structure, with the openings of two adjacent U-shaped structures arranged opposite to each other, so that the two adjacent U-shaped structures together form a limiting space to limit and accommodate the workpiece to be printed within the limiting space.

[0009] As one possible implementation, a stepped groove is provided on the side wall of the U-shaped structure, and the workpiece to be printed can be positioned and accommodated on any surface of the stepped groove.

[0010] In one possible implementation, the fasteners are L-shaped, with four fasteners distributed at the four corners of the workpiece to be printed, so that the four fasteners together form a limiting space to contain the workpiece to be printed within the limiting space.

[0011] In one possible implementation, the number of the grooves is at least one, and at least one groove is provided between two adjacent fasteners.

[0012] In one possible implementation, the number of support platforms is at least one, and the height of the support platform is equal to the height of the sidewall of the groove.

[0013] A second aspect of this application provides an engraving device, including the aforementioned positioning fixture. This positioning fixture, through a support platform and at least two fixing members, can stably fix the workpiece to be printed to ensure positioning accuracy, thereby preventing the workpiece from collapsing or deforming. It can also directly accommodate debris generated during engraving via grooves, preventing debris from contaminating the workpiece and the platform, thus ensuring the quality of subsequent processing.

[0014] The beneficial effects of the embodiments of this application include: The positioning fixture includes a base and at least two fixing members disposed on the base. A groove is provided on the base, and along the line connecting the at least two fixing members, the groove is located between the at least two fixing members. A support platform is disposed within the groove. The support platform supports the workpiece to be printed and clamps it in cooperation with the at least two fixing members, while the groove accommodates debris generated during the engraving process. This application effectively supports the workpiece to be printed through the support platform and effectively clamps it through the fixing members, providing a double fixation effect and preventing the bottom of the workpiece from being suspended, thus avoiding collapse and deformation caused by heat or impact during engraving. Furthermore, the groove collects debris, preventing debris accumulation on the bottom of the workpiece or the surface of the engraving platform during engraving. After engraving, cleaning is simple and can be completed, ensuring the subsequent processing quality of the workpiece. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Please refer to the reference. Figures 1 to 4 This application provides a positioning fixture 100, including a base 10 and at least two fixing members 20 disposed on the base 10. A groove 11 is provided on the base 10, and along the line connecting the at least two fixing members 20, the groove 11 is located between the at least two fixing members 20. A support platform 111 is disposed within the groove 11. The support platform 111 supports the workpiece 200 to be printed and clamps the workpiece 200 to be printed through the cooperation of the at least two fixing members 20, so as to accommodate the debris generated during the engraving of the workpiece 200 through the groove 11. This positioning fixture 100, through the cooperation of the support platform 111 and the at least two fixing members 20, can stably fix the workpiece 200 to be printed to ensure positioning accuracy and prevent the workpiece from collapsing and deforming. It can also directly accommodate the debris generated during the engraving of the workpiece through the groove 11, preventing debris from contaminating the workpiece and the platform, thereby ensuring the quality of subsequent processing.

[0022] It should be noted that the positioning fixture 100 includes a base 10 and at least two fixing members 20. The base 10 can be made of high-strength materials (such as aluminum alloy, acrylic sheet, or engineering plastic) to ensure no deformation when supporting the workpiece 200 to be printed and the fixing members 20, and to adapt to workpieces 200 of different weights. The overall size of the base 10 can be designed according to the size of the workpiece 200 to be printed. The larger the base 10, the larger the size of the workpiece 200 that the engraving equipment can engrave. The groove 11 is formed on the upper surface of the base 10 and can be centrally distributed along the line connecting the at least two fixing members 20. For example, the two fixing members 20 are centered along the line connecting the base 10. The base 10 is distributed along its length, and the groove 11 is located between the two along the length of the base 10. Its shape and size can be adapted to the engraving area of ​​the workpiece 200 to be printed. For example, a circular workpiece 200 to be printed corresponds to an arc-shaped groove 11, and a square workpiece 200 to be printed corresponds to a rectangular groove 11, so as to ensure that the engraving debris falls directly into the groove 11 and can eventually be discharged through the groove 11. For example, a chip removal hole is designed at the bottom of the groove 11, which is then removed by negative pressure or by gravity. Alternatively, the groove 11 can be directly connected along the line perpendicular to the connection of at least two fixing members 20 to avoid the accumulation of debris in the groove 11.

[0023] A support platform 111 is provided within the groove 11. The support platform 111 can be an integrally formed or detachable protrusion (such as a cylindrical boss or a rectangular boss) within the groove 11. Its top surface can be flush with the upper surface of the base 10, or in other words, as... Figures 1 to 3 As shown, there is at least one support platform 111. The height of each support platform 111 is equal to the height of the side wall of the groove 11, so as to ensure that the support platform 111 can effectively support the workpiece 200 after it is placed. At the same time, the fixing member 20 can effectively clamp the workpiece 200 to avoid the weight of the workpiece 200 being entirely pressed on the support platform 111. The top area of ​​the support platform 111 can be 30% to 50% of the bottom area of ​​the workpiece, which not only ensures the stability of the support platform 111 in supporting the workpiece 200, but also allows space for debris to fall, so as to avoid affecting the discharge of debris.

[0024] During actual assembly, firstly, the workpiece 200 to be printed (such as a substrate) is placed on the support platform 111 within the groove 11, ensuring that the engraving area of ​​the workpiece 200 is directly above the groove 11. Secondly, the actual position of the fixing member 20 is adjusted according to the size of the workpiece 200 to achieve a dual fixing effect of "support platform 111 supporting the bottom and fixing member 20 clamping the edge," thereby ensuring that the workpiece 200 will not wobble. Finally, the actual position of the workpiece 200 is checked through the visual positioning system of the engraving equipment. If there is a deviation, the actual position of the fixing member 20 can be finely adjusted to ensure that the positioning accuracy of the workpiece 200 meets the engraving requirements, and then engraving can proceed.

[0025] During actual engraving, firstly, the engraving equipment (such as a laser engraving machine or CNC milling cutter) engraves the surface of the workpiece 200 to be printed. The resulting debris falls directly into the groove 11 below under the action of gravity, avoiding accumulation on the surface of the workpiece 200 or the engraving platform. Secondly, due to the depth and width design of the groove 11, it can be ensured that the debris will not overflow within a certain period of time. Finally, after the engraving is completed, the workpiece 200 to be printed is removed, and the debris in the groove 11 is poured out, or the chip removal hole is opened to be sucked away by negative pressure or dropped by gravity.

[0026] Compared to existing technologies, this application effectively supports the workpiece 200 to be printed through the support platform 111, and also effectively clamps the workpiece 200 to be printed through the fastener 20. This not only provides a double fixation effect for the workpiece 200 to be printed, but also prevents the bottom of the workpiece 200 to be printed from being suspended, thereby avoiding collapse and deformation of the workpiece 200 to be printed due to heat or impact during engraving. In addition, this application also uses the groove 11 to collect debris, preventing debris from accumulating on the bottom of the workpiece 200 to be printed or on the surface of the engraving platform during engraving. After engraving, cleaning can be completed with simple cleaning, thereby ensuring the subsequent processing quality of the workpiece 200 to be printed.

[0027] As one possible implementation method, such as Figures 1 to 4 As shown, the positioning fixture 100 also includes a connector 30. The side wall of the groove 11 is provided with a mounting hole, and each fixing member 20 is provided with a connecting hole 21. The connector 30 passes through the connecting hole 21 and the mounting hole so that the fixing member 20 is assembled on the base 10.

[0028] It should be noted that the positioning fixture 100 also includes a connector 30 (such as a pin). Mounting holes are provided on both opposite sidewalls (such as the left and right sidewalls) of the groove 11, and a connecting hole 21 is provided on each fixing member 20. During actual assembly, according to the size of the workpiece to be processed, the connecting hole 21 of the fixing member 20 is aligned with the mounting hole on the sidewall of the groove 11, and then the connector 30 is passed through the connecting hole 21 and tightened to the mounting hole, thus assembling the fixing member 20 onto the base 10. In this way, the fixing member 20 and the base 10 are designed to be detachable, facilitating the replacement of components separately.

[0029] As one possible implementation method, such as Figures 1 to 4 As shown, in some embodiments, the positioning fixture 100 further includes a locking nut 40, the outer wall of the connector 30 is provided with threads, the connecting hole 21 is a strip hole, and the locking nut 40 is used to engage with the connector 30 in a threaded manner to lock the fixing member 20 at any position in the strip hole.

[0030] It should be noted that the positioning fixture 100 also includes a locking nut 40, the outer wall of the connector 30 is provided with threads, and the connecting hole 21 is a strip hole. The extension direction of the strip hole is along the line connecting at least two fixing parts 20. In actual assembly, the locking nut 40 and the connector 30 are initially in a loose state so that the connector 30 can slide freely relative to the strip hole. The actual position of the fixing part 20 relative to the base 10 can be flexibly adjusted according to the size of the workpiece to be processed. After the fixing part 20 moves to the target position, the locking nut 40 and the connector 30 are tightened to lock the fixing part 20 in the current position (i.e., the target position) so that the fixing part 20 can fix the workpiece 200 to be printed.

[0031] As one possible implementation method, such as Figures 1 to 4 As shown, in some other embodiments, the positioning fixture 100 further includes a locking nut 40, the outer wall of the connector 30 is provided with threads, and there are multiple connecting holes 21. The multiple connecting holes 21 are distributed at intervals along the line connecting at least two fixing members 20. The locking nut 40 is used to engage with the connector 30 to lock the fixing member 20 in any one of the connecting holes 21.

[0032] It should be noted that the positioning fixture 100 also includes a locking nut 40. The outer wall of the connector 30 is threaded, and there are multiple connecting holes 21. These connecting holes 21 are spaced apart along the line connecting at least two fixing members 20. During actual assembly, one connecting hole 21 can be flexibly selected and aligned with the mounting hole according to the size of the workpiece to be processed. Then, the connector 30 is passed through the connecting hole 21 and the mounting hole, and tightened with the locking nut 40 to lock the fixing member 20 within the connecting hole 21, thus fixing the workpiece 200 to be printed. Alternatively, there can be multiple mounting holes, spaced apart along the line connecting at least two fixing members 20. During actual assembly, one connecting hole 21 can be flexibly selected and aligned with one mounting hole according to the size of the workpiece to be processed. Then, the connector 30 is passed through the connecting hole 21 and the mounting hole, and tightened with the locking nut 40 to lock the fixing member 20 within the mounting hole, thus fixing the workpiece 200 to be printed.

[0033] As one possible implementation method, such as Figures 1 to 4 As shown, in this embodiment, the fixing member 20 is a U-shaped structure, and the openings of two adjacent U-shaped structures are arranged opposite to each other so that the two adjacent U-shaped structures together form a limiting space to limit and accommodate the workpiece 200 to be printed within the limiting space.

[0034] It should be noted that the fixing member 20 has a U-shaped structure. The width of the opening of the U-shaped structure should be slightly larger than the width of the workpiece 200 to be printed, so as to ensure that the workpiece 200 can be smoothly placed in without shaking. The depth of the U-shaped groove of the U-shaped structure (i.e., the length along the line connecting at least two fixing members 20) should be able to cover the edge of the workpiece 200 to a certain extent, so as to further improve the clamping and limiting effect of the fixing member 20 on the workpiece 200 to be printed. The openings of two adjacent U-shaped structures are arranged opposite to each other. For example, the opening of the U-shaped structure on the left faces to the right and the opening of the U-shaped structure on the right faces to the left, so as to form a gripper structure. The two adjacent U-shaped structures together form a limiting space. The shape and size of the limiting space depend on the shape and size of the workpiece 200 to be printed. It is only necessary to ensure that the workpiece 200 to be printed can be contained and limited within the limiting space.

[0035] Furthermore, as one possible implementation method, such as Figures 1 to 4 As shown, a stepped groove 22 is provided on the side wall of the U-shaped structure, and the workpiece 200 to be printed can be positioned and accommodated on any platform of the stepped groove 22.

[0036] It should be noted that the side wall of the U-shaped structure is provided with stepped grooves 22, which form a "layered limiting space" through the platform of different heights. In other words, the opening width of the U-shaped structure has multiple dimensions, so that the workpiece 200 to be printed can select the appropriate platform according to its own width. Thus, the workpiece 200 to be printed can be accommodated in the limiting space of different platforms, so that the same set of U-shaped fasteners 20 can simultaneously accommodate multiple sizes of workpieces 200 to be printed. This solves the limitation of traditional fasteners that can only adapt to workpieces of fixed size, and greatly improves the versatility of the positioning fixture 100 while ensuring positioning accuracy.

[0037] Similarly to the above embodiments, in other embodiments, the fastener 20 can also be an L-shaped structure, with four fasteners 20 distributed at the four corners of the workpiece 200 to be printed, so that the four fasteners 20 together form a limiting space to limit and accommodate the workpiece 200 to be printed within the limiting space. The specific principle will not be described in detail here.

[0038] As one possible implementation method, such as Figures 1 to 3As shown, there is at least one groove 11, with at least one groove 11 provided between two adjacent fixing members 20 to ensure that the capacity of the groove 11 can meet the chip production of a single engraving. Each groove 11 contains at least one support platform 111 to ensure that even when the distance between two adjacent fixing members 20 is large, a greater number of support platforms 111 can still effectively support the workpiece 200 to be printed. The multiple support platforms 111 within each groove 11 can be distributed along the line connecting at least two fixing members 20, or perpendicular to the line connecting at least two fixing members 20. Alternatively, when the groove 11 is sufficiently large, the multiple support platforms 111 within each groove 11 can be arranged in a matrix to increase the support for the bottom of the workpiece 200 to be printed.

[0039] This application also provides an engraving device, such as a laser engraving device, including the aforementioned positioning fixture 100. Since the structure and beneficial effects of the positioning fixture 100 have been described in detail in the foregoing embodiments, they will not be repeated here.

[0040] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0041] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
