Description

Technical Field

[0001] The invention relates to the technical field of heat sink product manufacturing, and in particular to a laser pattern processing tool and a processing method for a heat sink product with a side circuit. Background Art

[0002] A ceramic substrate is a circuit board made of ceramic material as the base, while a thin-film circuit is a circuit formed by depositing a metal or dielectric film with a thickness of microns on the surface of the substrate. Thin-film circuits with ceramic substrates as the core dielectric material are widely used in the fields of communications and aerospace due to their high interconnection density and micron-level line accuracy.

[0003] The metallization circuit pattern of the traditional thin film circuit cannot meet the lateral transmission capacity. The Chinese patent application with publication number CN117979560A describes a method for making a thin film circuit heat sink product with a side circuit, including the following steps:

[0004] S1, first cleaning and post-cleaning treatment, taking the ceramic substrate for first cleaning and post-cleaning treatment;

[0005] S2, the first cutting, cutting parallel to one end of the ceramic substrate in the width direction or the length direction to form a processing area and a first supporting end and a second supporting end connected to both ends of the processing area, wherein the base strips and the strip grooves are arranged alternately in the processing area;

[0006] S3, second washing and drying;

[0007] S4, magnetron sputtering, magnetron sputtering to form a Ti layer, a Pt layer, and a Au layer;

[0008] S5, cutting for the second time, cutting and removing the first supporting end and the second supporting end to form base strips that are independent and separated from each other;

[0009] S6, laser processing, laser processing the base strip to form product graphics on the base strip;

[0010] S7, third washing and drying;

[0011] S8, the third cutting, cutting the base strips into separate individual products.

[0012] In step S4, the metal layer exists on the front side and its adjacent side, and at this time it is a complete metal surface. In S6, it is necessary to perform two laser scanning operations on the front side and the side respectively to remove part of the metal layer and retain the product pattern. In step S6, generally, the base strip is clamped to ensure the positioning characteristics of the laser scanning. Since the size of the base strip is 0.2 mm in thickness, 3 cm in length, and 0.5 cm in width, its thickness dimension is particularly small. Under the spring pressure, due to the deformation of the base strip under strong clamping and unable to release, the white base is a rigid body to block. Due to the small size in the thickness direction and the small side contact surface, it is easy to bounce when assembled under the laser, resulting in the base strip being in an inclined state. Since the laser will perform margin scanning during scanning, it will scan to the side, resulting in serious side pattern defects. Summary of the Invention

[0013] The purpose of the present invention is to provide a laser graphic processing tooling and processing method for a product with a side circuit heat sink, which can absorb the pressure on the base strip, thereby avoiding deformation or bouncing and tilting of the base strip due to the pressure at both ends.

[0014] To solve the above technical problems, the present invention adopts the following solutions:

[0015] In a first aspect, a laser graphic processing tooling for a product with a side circuit heat sink includes a base. An activity member is provided on the base. A support surface for supporting one side end of the base strip is provided on the base. An activity surface for pressing the base strip against the support surface is provided on the activity member. Arc-shaped spring pieces are provided on both the support surface and the activity surface, and the arc-shaped spring pieces on the support surface and the arc-shaped spring pieces on the activity surface protrude towards each other. Its function is that through the setting of the arc-shaped spring pieces, the rigid fixation of the base strip by the original support surface and the activity surface is converted into elastic fixation of the relative two side ends of the base strip, so that the pressure received by the base strip when being clamped can be released to the arc-shaped spring pieces, thereby avoiding deformation of the base strip when being clamped and assembled under the laser or tilting of the base strip caused by bouncing.

[0016] Further, a rigid section is provided on the arc-shaped spring piece, and a contact surface for directly contacting the base strip is provided on the rigid section. The contact surfaces on the support surface and the activity surface are arranged in parallel. Its function is that through the setting of the contact surface, the line contact between the arc-shaped spring piece and the base strip can be changed into surface contact, and the friction between the arc-shaped spring piece and the base strip can be increased by increasing the contact area between the arc-shaped spring piece and the base strip, so that the arc-shaped spring pieces on the relative two sides of the base strip can firmly clamp the base strip.

[0017] Further, the rigid section is sleeved on the arc-shaped spring piece in a sleeve shape. The rigid section is located in the middle of the convex part of the arc-shaped spring piece, and the middle part of the convex part of the arc-shaped spring piece is flat. Its function is that through the design of the shape of the middle part of the convex part of the arc-shaped spring piece, the rigid section can be clamped on the middle part of the convex part of the arc-shaped spring piece.

[0018] Further, a guiding groove extending along the length direction of the base is provided on the top surface of the base. The movable part is arranged in the guiding groove. A spring is provided between one end of the movable part and the base. A base placement groove perpendicular to the guiding groove is provided on the top surface of the base. A movable part placement groove perpendicular to the guiding groove is provided on the movable part. The supporting surface is the side wall of the base placement groove facing the spring, and the movable surface is the side wall of the movable part placement groove facing away from the spring.

[0019] Further, the length of the arc-shaped spring piece on the supporting surface is greater than the length of the arc-shaped spring piece on the movable surface. Its function is that since the supporting surface is arranged in a dislocation manner with the movable surface in the length direction of the guiding groove, through the design of the lengths of the arc-shaped spring pieces on the supporting surface and the movable surface, the middle parts of the arc-shaped spring pieces on the supporting surface can correspond to the middle parts of the arc-shaped spring pieces on the movable surface.

[0020] Further, at least two base placement grooves are distributed along the length direction of the guiding groove on the base, and at least two movable part placement grooves are distributed along the length direction of the movable part on the movable part. The number of base placement grooves is equal to the number of movable part placement grooves. Its function is that through the design of the numbers of the base placement grooves and the movable part placement grooves, a plurality of base strips can be clamped and fixed simultaneously.

[0021] Further, the arc-shaped spring piece on the supporting surface includes connecting parts arranged at the left and right ends of the convex part. An embedding block for connecting the two connecting parts on the arc-shaped spring piece is connected to the arc-shaped spring piece on the supporting surface. An embedding groove for the embedding block to be embedded and move along the length direction of the base placement groove is provided on the supporting surface. Its function is that through the arrangement of the embedding block and the embedding groove, the arc-shaped spring piece on the supporting surface can be moved out of the guiding groove during the movement of the movable part in the guiding groove, avoiding the influence of the arc-shaped spring piece on the supporting surface on the movement of the movable part in the guiding groove, and at the same time, the arc-shaped spring piece on the supporting surface can be moved to a position corresponding to the arc-shaped spring piece on the movable surface when clamping the base strip is needed.

[0022] Further, the embedding groove penetrates through the side wall of the base and is arranged at the bottom of the supporting surface. A connecting strip connecting the bottom surfaces of all the embedding blocks is further included, and the connecting strip is located below the base placement groove. Its function is that through the arrangement of the connecting strip, the arc-shaped spring pieces on all the embedding blocks can be driven to move together, which is convenient to use; through the design of the position of the connecting strip, the space above the base strip can be prevented from being blocked by the connecting strip, enabling the base strip to be smoothly processed by laser.

[0023] Furthermore, an adjustment groove parallel to the embedding groove is provided on one side of the embedding block facing the base placement groove. An extension part for extending into the adjustment groove is provided at one end of the connecting part facing the adjustment groove. The length of the adjustment groove is greater than the width of the guiding groove. A communication port communicating with the adjustment groove is provided at the top of the connecting strip. A through port for communicating with the communication port is provided on the top surface of the base within 3 cm from the guiding groove. A clamping shaft for passing through the communication port and the through port is provided through the connecting part. A plurality of clamping holes for inserting the clamping shaft are evenly distributed along the length direction of the bottom surface of the adjustment groove. Its function is that through the settings of the adjustment groove, the connecting part, the communication port, the through port, the clamping shaft, and the clamping holes, the bending degree of the arc-shaped spring piece can be adjusted by moving the connecting part to different clamping holes and connecting the clamping shaft through the connecting part to connect with the clamping hole, so as to adapt to base strips of different sizes. It can not only clamp the left and right ends of the base strip to make the upper or lower end of the base strip face upward, but also clamp the upper and lower ends of the base strip to make the left or right end of the base strip face upward.

[0024] Second aspect, a laser graphic processing method for a product with a side circuit heat sink, comprising the following steps:

[0025] S1, pull the movable part to leave a space for placing the base strip between the supporting surface and the movable surface;

[0026] S2, place the base strip between the arc-shaped spring pieces on the supporting surface and the arc-shaped spring pieces on the movable surface, and the fixation of the base strip is completed.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. Through the setting of the arc-shaped spring pieces, the original rigid fixation of the base strip by the supporting surface and the movable surface is converted into elastic fixation of the relative two side ends of the base strip, so that the pressure received by the base strip when being clamped can be released to the arc-shaped spring pieces, thereby avoiding the deformation of the base strip easily caused by being clamped and assembled under the laser or the inclination of the base strip caused by bouncing.

[0029] 2. Through the setting of the contact surface, the line contact between the arc-shaped spring piece and the base strip can be changed into surface contact, and the friction force between the arc-shaped spring piece and the base strip is increased by increasing the contact area between the arc-shaped spring piece and the base strip, so that the arc-shaped spring pieces on the relative two sides of the base strip can firmly clamp the base strip.

An active part 2 is provided on the base 1. A supporting surface 3 for supporting one side end of the base strip is provided on the base 1. An active surface 4 for pressing the base strip against the supporting surface 3 is provided on the active part 2. Arc-shaped spring pieces 5 are provided on both the supporting surface 3 and the active surface 4. The arc-shaped spring piece 5 on the supporting surface 3 and the arc-shaped spring piece 5 on the active surface 4 protrude towards each other. Its function is that through the setting of the arc-shaped spring pieces 5, the rigid fixation of the base strip by the original supporting surface 3 and the active surface 4 is converted into elastic fixation of the relative two side ends of the base strip, so that the pressure received by the base strip when being clamped can be released onto the arc-shaped spring pieces 5, thereby avoiding deformation of the base strip when it is clamped and assembled under the laser or tilting of the base strip caused by bouncing.

[0042] Specifically, as Figure 2 shown, a rigid section 6 is provided on the arc-shaped spring piece 5. A contact surface 7 for directly contacting the base strip is provided on the rigid section 6. The contact surface 7 on the supporting surface 3 and the contact surface 7 on the active surface 4 are arranged in parallel. Its function is that through the setting of the contact surface 7, the line contact between the arc-shaped spring piece 5 and the base strip can be changed into surface contact, and the friction force between the arc-shaped spring piece 5 and the base strip can be increased by increasing the contact area of the contact surface 7 between the arc-shaped spring piece 5 and the base strip, so that the arc-shaped spring pieces 5 on the relative two sides of the base strip can firmly clamp the base strip.

[0043] Specifically, as Figure 2 shown, the rigid section 6 is sleeved on the arc-shaped spring piece 5 in a sleeve shape. The rigid section 6 is located in the middle of the protrusion of the arc-shaped spring piece 5, and the middle part of the protrusion of the arc-shaped spring piece 5 is flat.

In the length direction of the active part 2, the length of the limiting block is less than the length of the limiting groove. A cover plate can be provided above the spring 9 and the limiting groove to prevent the active part 2 from bouncing up.

[0045] Specifically, as Figure 2As shown, the length of the arc-shaped spring piece 5 on the support surface 3 is greater than the length of the arc-shaped spring piece 5 on the movable surface 4. Its function is that since the support surface 3 is arranged offset from the movable surface 4 in the length direction of the guide groove 8, through the design of the lengths of the arc-shaped spring piece 5 on the support surface 3 and the arc-shaped spring piece 5 on the movable surface 4, the middle part of the arc-shaped spring piece 5 on the support surface 3 can correspond to the middle part of the arc-shaped spring piece 5 on the movable surface 4.

[0046] Specifically, as Figure 1 , Figure 3 shown, at least two base placement grooves 10 are distributed along the length direction of the guide groove 8 on the base 1, and at least two movable member placement grooves 11 are distributed along the length direction of the movable member 2 on the movable member 2. The number of the base placement grooves 10 is equal to the number of the movable member placement grooves 11. Its function is that through the design of the numbers of the base placement grooves 10 and the movable member placement grooves 11, multiple base strips can be clamped and fixed simultaneously.

[0047] Specifically, as Figure 4 shown, the arc-shaped spring piece 5 on the support surface 3 includes connecting portions 12 provided at the left and right ends of the protrusion. An embedding block 13 for connecting the two connecting portions 12 on the arc-shaped spring piece 5 is connected to the arc-shaped spring piece 5 on the support surface 3. An embedding groove 14 for the embedding block 13 to be embedded and move along the length direction of the base placement groove 10 is provided on the support surface 3. Its function is that through the arrangement of the embedding block 13 and the embedding groove 14, the arc-shaped spring piece 5 on the support surface 3 can be moved out of the guide groove 8 during the movement of the movable member 2 in the guide groove 8, avoiding the influence of the arc-shaped spring piece 5 on the support surface 3 on the movement of the movable member 2 in the guide groove 8, and at the same time, the arc-shaped spring piece 5 on the support surface 3 can be moved to a position corresponding to the arc-shaped spring piece 5 on the movable surface 4 when clamping the base strip is needed.

[0048] Specifically, as Figure 3 shown, the embedding groove 14 penetrates through the side wall of the base 1 and is provided at the bottom of the support surface 3. It further includes a connecting strip 15 connecting the bottom surfaces of all the embedding blocks 13, and the connecting strip 15 is located below the base placement groove 10. Its function is that through the arrangement of the connecting strip 15, the arc-shaped spring pieces 5 on all the embedding blocks 13 can be driven to move together, which is convenient to use; through the design of the position of the connecting strip 15, the space above the base strip can be avoided being blocked by the connecting strip 15, enabling the base strip to be smoothly laser processed.

[0049] Specifically, as Figure 4As shown in the figure, on one side of the embedding block 13 facing the base placement groove 10, there is an adjustment groove 16 parallel to the embedding groove 14. At one end of the connecting part 12 facing the adjustment groove 16, there is an extension part 17 for extending into the adjustment groove 16. The length of the adjustment groove 16 is greater than the width of the guiding groove 8. On the top of the connecting strip 15, there is a communication port 18 communicating with the adjustment groove 16. On the top surface of the base 1, within 3 CM from the guiding groove 8, there is a through port 19 for communicating with the communication port 18. A clamping shaft 20 for passing through the communication port 18 and the through port 19 is provided through the connecting part 12. On the bottom surface of the adjustment groove 16, a plurality of clamping holes 21 for inserting the clamping shaft 20 are evenly distributed along the length direction of the adjustment groove 16. The embedding block 13 is provided with a through hole for the clamping shaft 20 to pass through. Its function is that through the settings of the adjustment groove 16, the connecting part 12, the communication port 18, the through port 19, the clamping shaft 20, and the clamping holes 21, the bending degree of the arc-shaped spring piece 5 can be adjusted by moving the connecting part 12 to different clamping holes 21 and connecting with the clamping hole 21 by passing the clamping shaft 20 through the connecting part 12, so as to adapt to base strips of different sizes. It can not only clamp the left and right ends of the base strip to make the upper or lower end of the base strip face upward, but also clamp the upper and lower ends of the base strip to make the left or right end of the base strip face upward.

[0050] In a second aspect, a laser pattern processing method for a side-circuit heat sink product includes the following steps:

[0051] S1. Pull the movable part 2 to leave a space for placing the base strip between the supporting surface 3 and the movable surface 4;

[0052] S2. Place the base strip between the arc-shaped spring pieces 5 on the supporting surface 3 and the arc-shaped spring pieces 5 on the movable surface 4, and the fixing of the base strip is completed.

[0053] The working principle of this embodiment is described as follows: As Figure 5 shown, when it is necessary to clamp the left and right end faces of the base strip, first pull the movable part 2 to make the movable part placement groove 11 and the embedding groove 14 correspond and communicate. Then push the connecting strip 15 to push the embedding block 13 into and through the movable part placement groove 11, so that the rigid sections 6 on the arc-shaped spring piece 5 on the supporting surface 3 correspond to the rigid sections 6 on the arc-shaped spring piece 5 on the movable surface 4. Then fix the embedding block 13 and the clamping hole 21 near the edge of the adjustment groove 16 through the clamping shaft 20, and expand the base strip between two adjacent arc-shaped spring pieces 5 arranged oppositely, so that both the left and right ends of the base strip are in contact with the contact surface 7, thus completing the clamping of the left and right end faces of the base strip, and enabling the bottom or top surface of the base strip to face upward for laser processing from top to bottom;

[0054] As Figure 6As shown, when it is necessary to clamp the left and right end faces of the base strip, the clamping shaft 20 is pulled out, the embedding block 13 is moved to the center position of the adjustment slot 16, and the clamping shaft 20 is passed through the embedding block 13 and the clamping hole 21 in the center position on the adjustment slot 16, so that the arching amplitude of the arc-shaped spring piece 5 on the support surface 3 is increased and fixed. Combined with the action of the spring 9, the front and back surfaces of the base strip can be clamped, so that the bottom surface or the top surface of the base strip can face upward for laser processing from top to bottom.

[0055] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. According to the technical essence of the present invention, within the spirit and principle of the present invention, any simple modification, equivalent replacement, and improvement made to the above embodiments still fall within the protection scope of the technical solution of the present invention.
