Description

Technical Field

[0001] The present invention relates to the technical field of heat sink product manufacturing, and particularly relates to a laser graphic processing tooling 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 a ceramic material, and a thin film circuit is a circuit formed by depositing a metal or dielectric thin film with a micron-level thickness on the surface of the substrate. The thin film circuit with a ceramic substrate as the core dielectric material has been widely used in the communication and aerospace fields due to its advantages of high interconnect density and micron-level line accuracy.

[0003] The metallization preparation of the circuit pattern of the traditional thin film circuit cannot meet the lateral transmission ability. The Chinese patent application with the publication number CN117979560A describes a method for manufacturing a thin film circuit heat sink product with a side circuit, including the following steps: S1, the first cleaning and post-cleaning treatment, taking a ceramic substrate for the first cleaning and post-cleaning treatment; S2, the first cutting, cutting parallelly from one end of the ceramic substrate along the width direction or the length direction to form a processing area and a first support end and a second support end connected to both ends of the processing area. In the processing area, base strips and strip-shaped grooves are arranged alternately; S3, the second cleaning and drying; S4, magnetron sputtering, magnetron sputtering to form a magnetron sputtered metal layer of a Ti layer, a Pt layer, and an Au layer; S5, the second cutting, cutting off the first support end and the second support end to form mutually independent and separated base strips; S6, laser processing, laser processing the base strips to form product patterns on the base strips; S7, the third cleaning and drying; S8, the third cutting, cutting the base strips into mutually independent and separated single products.

[0004] In step S4, the metal layer exists on both the front surface and its adjacent side surface, and at this time, it is a complete metal surface. In S6, it is necessary to perform 2 laser scanning operations on the front surface and the side surface respectively to remove part of the metal layer and retain the product pattern. In step S6, generally, the base strips are clamped to ensure the positioning characteristics of the laser scanning. Since the size of the base strips is 0.2 mm in thickness, 3 cm in length, and 0.5 cm in width, and its thickness dimension is particularly small, under the spring pressure, due to the deformation of the base strips caused by being strongly clamped and unable to be released, and the white base is a rigid body to block, due to the small dimension in the thickness direction and the small side contact surface, it is easy to generate bouncing when assembled under the laser, resulting in the base strips being in an inclined state. Since the laser will perform margin scanning during the scanning of the pattern, it will scan to the side surface, resulting in serious defects in the side surface pattern. Summary of the Invention

[0005] The object of the present invention is to provide a laser pattern 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 left and right ends.

[0006] To solve the above technical problems, the present invention adopts the following solutions: In the first aspect, a laser pattern processing tooling for a product with a side circuit heat sink includes a base, an active part is provided on the base, a support surface for supporting one side end of the base strip is provided on the base, and an active surface for pressing the base strip against the support surface is provided on the active part. Arc-shaped spring pieces are provided on both the support surface and the active surface, and the arc-shaped spring pieces on the support surface protrude towards the arc-shaped spring pieces on the active surface. Its function is that through the setting of the arc-shaped spring pieces, the rigid fixation of the original support surface and the active surface to the base strip 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 it is clamped and assembled under the laser or tilting of the base strip caused by bouncing.

[0007] 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 active 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 force 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.

[0008] Further, the rigid section is sleeved on the arc-shaped spring piece in a ring shape, the rigid section is located in the middle of the protrusion of the arc-shaped spring piece, and the middle part of the protrusion of the arc-shaped spring piece is flat. Its function is that through the design of the shape of the middle part of the protrusion of the arc-shaped spring piece, the rigid section can be stuck on the middle part of the protrusion of the arc-shaped spring piece.

[0009] Further, a guiding groove extending along the length direction of the base is provided on the top surface of the base, the active part is arranged in the guiding groove, a spring is provided between one end of the active part and the base, a base placing groove perpendicular to the guiding groove is provided on the top surface of the base, an active part placing groove perpendicular to the guiding groove is provided on the active part, the support surface is the side wall of the base placing groove facing the spring, and the active surface is the side wall of the active part placing groove facing away from the spring.

[0010] Furthermore, the length of the arc-shaped spring piece on the support surface is greater than the length of the arc-shaped spring piece on the movable surface. Its function is that since the support 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 support surface and the movable surface, the middle parts of the arc-shaped spring pieces on the support surface can correspond to the middle parts of the arc-shaped spring pieces on the movable surface.

[0011] Furthermore, 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, multiple base strips can be clamped and fixed simultaneously.

[0012] Furthermore, the arc-shaped spring piece on the support surface includes connecting parts arranged at the left and right ends of the protrusion. 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 support surface. An embedding groove for the embedding block to be embedded and move along the length direction of the base placement groove is arranged on the support surface. Its function is that through the setting of the embedding block and the embedding groove, the arc-shaped spring piece on the support 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 support surface on the movement of the movable part in the guiding groove, and at the same time, the arc-shaped spring piece on the support surface can be moved to a position corresponding to the arc-shaped spring piece on the movable surface when clamping the base strip is required.

[0013] Furthermore, the embedding groove penetrates through the side wall of the base and is arranged at the bottom of the support 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 setting 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.

[0014] Further, 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 connection 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 connection 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 connection part, the communication port, the through port, the clamping shaft, and the clamping holes, the bending degree of the arc spring piece can be adjusted by moving the connection part to different clamping holes and connecting the clamping shaft through the connection 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.

[0015] In a second aspect, a laser graphic processing method for a side-circuit heat sink product includes the following steps: S1, pull the movable part to leave a space for placing the base strip between the supporting surface and the movable surface; S2, place the base strip between the arc spring pieces on the supporting surface and the arc spring pieces on the movable surface, and the fixing of the base strip is completed.

[0016] The beneficial effects of the present invention are as follows: 1. Through the setting of the arc spring pieces, the original rigid fixing of the base strip by the supporting surface and the movable surface is converted into elastic fixing of the relative two side ends of the base strip, so that the pressure received by the base strip during clamping can be released onto the arc spring pieces, thereby avoiding deformation or tilting of the base strip caused by bouncing when the base strip is clamped and assembled under the laser. 2. Through the setting of the contact surface, the line contact between the arc spring piece and the base strip can be changed into surface contact, and the friction force between the arc spring piece and the base strip can be increased by increasing the contact area between the arc spring piece and the base strip, so that the arc spring pieces on the relative two sides of the base strip can firmly clamp the base strip.

On the movable part 2, there is a movable surface 4 for pressing the base strip against the support surface 3. Arc-shaped spring pieces 5 are provided on both the support surface 3 and the movable surface 4, and the arc-shaped spring pieces 5 on the support surface 3 and the arc-shaped spring pieces 5 on the movable surface 4 bulge towards each other. Its function is that through the setting of the arc-shaped spring pieces 5, the original rigid fixation of the support surface 3 and the movable surface 4 to the base strip 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 or tilting of the base strip caused by bouncing when the base strip is clamped and assembled under the laser.

[0023] Specifically, as Figure 2 shown, on the arc-shaped spring piece 5, there is a rigid section 6, and on the rigid section 6, there is a contact surface 7 for directly contacting the base strip. The contact surface 7 on the support surface 3 and the contact surface 7 on the movable 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 by increasing the contact area of the contact surface 7 between the arc-shaped spring piece 5 and the base strip, the friction force between the arc-shaped spring piece 5 and the base strip can be increased, so that the arc-shaped spring pieces 5 on the relative two sides of the base strip can firmly clamp the base strip.

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

[0026] 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 length of the arc-shaped spring piece 5 on the support surface 3 and the length of 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.

[0027] 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 part placement grooves 11 are distributed along the length direction of the movable part 2 on the movable part 2.

Its function is that through the design of the number of the base placement grooves 10 and the movable part placement grooves 11, a plurality of base strips can be clamped and fixed simultaneously.

[0028] Specifically, as Figure 4 shown, the arc-shaped spring piece 5 on the support surface 3 includes connecting parts 12 arranged at the left and right ends of the protrusion. An embedding block 13 for connecting the two connecting parts 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 setting 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 part 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 part 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 required.

[0029] Specifically, as Figure 3 shown, the embedding groove 14 penetrates through the side wall of the base 1 and is arranged at the bottom of the support surface 3. A connecting strip 15 connecting the bottom surfaces of all the embedding blocks 13 is further included, and the connecting strip 15 is located below the base placement groove 10. Its function is that through the setting 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 prevented from being blocked by the connecting strip 15, enabling the base strip to be smoothly processed by laser.

[0030] 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 spring piece 5 can be adjusted by moving the connecting part 12 to different clamping holes 21 and connecting the clamping shaft 20 through the connecting part 12 to connect with the clamping hole 21, so as to adapt to base strips of different sizes.

[0032] 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 segments 6 on the arc spring piece 5 on the support surface 3 correspond to the rigid segments 6 on the arc 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 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, thereby 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; 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 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.
