To effectively solve the heat dissipation problem, it is usually chosen to embed a high-thermal-conductivity metal block in the PCB for heat dissipation. Before embedding the metal block, it is generally necessary to brown the metal sheet to clean and roughen the surface of the metal block and improve the bonding strength of the metal block.

[0003] The traditional method of browning metal sheets is to manually stick a high temperature resistant tape on the carrier frame, then manually stick the metal block on the tape, and then drag the carrier frame through the horizontal browning line to perform the browning process. The traditional method is not only time-consuming and labor-intensive, but also has very low work efficiency. Summary of the invention

[0006] It can be seen from the above scheme that by setting a material moving device, it is used to push the workpieces continuously conveyed from the material trough to the bottom of the tape one by one, so that the two adjacent workpieces pasted on the tape maintain a preset distance; by setting a downward pressing glue sticking device, it is used to automatically stick the workpiece on the tape instead of manual operation; by setting a tape pulling device, it is used to pull the tape according to a preset distance, and reserve enough space for the subsequent workpieces, so as to achieve the purpose of the preset distance between two adjacent workpieces; by setting a lifting tape sticking device, it is used to drive the carrier frame to move toward the tape, so that the tape between two adjacent workpieces is automatically stuck on the carrier frame, and the workpiece is located in the through hole of the carrier frame, which is convenient for subsequent browning treatment; by setting a cutting device, it is used to automatically cut off the tape after a row of workpieces are pasted on the carrier frame, so as to facilitate the next sticking operation. The present invention replaces traditional manual operations with automated operations, which has the advantages of saving time, saving manpower, reducing costs and improving efficiency.

[0007] A further solution is that the supporting plate and the lower pressing plate extend toward one side of the cutting device along the extending direction of the adhesive tape respectively, and the width of the lower pressing plate is greater than the width of the adhesive tape.

[0008] It can be seen from the above scheme that by arranging the supporting part and the lower pressure plate to extend along the extension direction of the tape, when the lower pressure plate is pressed down, multiple workpieces can be pressed by the lower pressure plate at the same time, that is, each workpiece is pressed against the tape for multiple times, which is beneficial to improve the bonding strength between the workpiece and the tape; by arranging the supporting plate to extend downwardly toward the bottom of the cutting device so as to be as close as possible to the cutting position of the tape, it is beneficial to avoid the elongation and deformation of the tape during cutting, thereby ensuring the cutting effect and efficiency.

[0014] It can be seen from the above scheme that by providing the steering wheel, on the one hand, the purpose of steering the tape is achieved, and on the other hand, it can also play a tensioning role, making it easier for the workpiece to be well adhered to the tape.

[0015] A further solution is that the tape pulling device further comprises a mounting frame, the mounting frame is arranged along the extending direction of the tape, the clamping claw is movably arranged on the mounting frame, and the height of the clamping claw corresponds to the height of the tape.

[0016] It can be seen from the above solution that by arranging the clamping claw on the mounting frame, the clamping claw can move back and forth at a preset height, ensuring that the clamping claw can clamp the tape.

[0017] A further solution is that the jacking tape device also includes a tape translation seat, which is arranged below the tape, and the lifting platform is arranged on the tape translation seat, and the tape translation seat can drive the lifting platform to move along the direction perpendicular to the extension of the tape.

[0018] It can be seen from the above scheme that after a section of tape is pasted on the carrier frame, the lifting platform can be driven to move along the direction perpendicular to the extension of the tape through the tape translation seat, which is convenient for pasting the next section of tape, so that multiple parallel sections of tape can be pasted on the carrier frame at the same time, which is beneficial to increase the number of workpieces on the carrier frame.

[0019] A further solution is that a plurality of mutually matching saw teeth are arranged inside the clamping opening of the clamping jaw.

[0020] It can be seen from the above scheme that the provision of saw teeth is helpful to improve the clamping force between the tape and the clamping claws, thereby avoiding accidental separation of the tape and the clamping claws.

[0021] A further solution is that the cutting device includes a cutting head and a cutting drive assembly, the cutting head is arranged at the ends of the lower pressure plate and the support plate, the cutting drive assembly drives the cutting head to move toward the tape, and in the extension direction of the tape, the cutting head has a preset distance from the end of the support plate and the end of the lower pressure plate respectively.

[0038] See also Figure 1 and Figure 2 The workpiece gluing and taping machine provided by the present invention is mainly used to produce or assist in the production of 5G products, that is, the present invention is mainly used to assist in the production of metal sheets embedded in PCBs for 5G products, so as to facilitate the browning treatment of the metal sheets to improve the production efficiency of the metal sheets. The metal sheets in this embodiment are copper sheets.

[0039] The workpiece gluing and taping machine comprises a working platform 1, a feeding device 2, a material moving device 3, a gluing pressing device 4, a tape pulling device 5, a lifting and taping device 6 and a cutting device 7. The working platform 1 is a rectangular box structure, and the feeding device 2, the material moving device 3, the gluing pressing device 4, the tape pulling device 5, the lifting and taping device 6 and the cutting device 7 are all arranged on the working platform 1. For the convenience of explanation, the feeding direction of the feeding device 2 is set to the X direction, the direction perpendicular to the feeding direction in the horizontal plane is set to the Y direction, and the vertical direction is set to the Z direction.

[0040] The feeding device 2 includes a feeding platform 21, a trough 22 and two vibrators 23. The trough 22 extends along the X direction and is simultaneously arranged on two vibrators 23. The vibrators 23 are linear vibrators 23. Each vibrator 23 has the same vibration frequency and is used to drive the workpiece 9 placed in the trough 22 to automatically move from the feeding end of the trough 22 to the discharging end of the trough 22, that is, to drive the workpiece 9 to move along the X direction to the material moving device 3. The feeding platform 21 is located on one side of the width direction of the trough 22, and is used to temporarily store the workpiece 9, so as to facilitate manual placement of the workpieces 9 on the feeding platform 21 one by one into the feeding end of the trough 22. In this embodiment, the width of the trough 22 is equal to or slightly greater than the length of the workpiece 9, and the workpiece 9 is placed in the trough 22 in a horizontal manner.

[0041] See also Figures 3 to 9 , a material pushing platform, an in-place detection device and a material moving device 3 are arranged at the discharge end of the trough 22, and the material pushing platform is flush with the bottom of the trough 22. The in-place detection device includes a detection mounting seat 8 and an in-place detector (not shown in the figure), the detection mounting seat 8 is arranged above the material pushing platform, and the in-place detector is an optical fiber sensor, which is arranged on the detection mounting seat 8 and emits detection light toward a preset position to detect whether the workpiece 9 is delivered in place, and if it is detected in place, the material moving device 3 is triggered to perform a material moving action. The preset position refers to the outer side of the discharge end of the trough 22, that is, the closest position where the workpiece 9 just leaves the trough 22 from the discharge end of the trough 22, so that when the workpiece 9 reaches the preset position, the workpiece 9 can move along the extension direction perpendicular to the trough 22 under the push of an external force, that is, move along the Y direction.

[0042] The material moving device 3 includes a material moving mounting seat 31, a material moving Y-direction translation seat 32, a material moving X-direction translation seat 33, a material pushing block 34 and a material pushing drive assembly 35. The material moving mounting seat 31 is arranged on the working platform 1, the material moving Y-direction translation seat 32 is arranged on the material moving mounting seat 31 and can move along the Y direction; the material moving X-direction translation seat 33 is arranged on the material moving Y-direction translation seat 32 and can move along the X direction; the material pushing drive assembly 35 and the material pushing block 34 are both arranged on the material moving X-direction translation seat 33, and the material pushing drive assembly 35 is preferably a cylinder, which is used to drive the material pushing block 34 to move along the Y direction. In this embodiment, the material moving Y-direction translation seat 32 and the material moving X-direction translation seat 33 both realize their respective movement adjustment through a screw transmission structure, which is a conventional technical means in the field and will not be described in detail here.

[0043] One end of the pusher block 34 away from the pusher drive assembly 35 is located on the pusher platform and outside the discharge end of the trough 22. The extension direction of the pusher block 34 is perpendicular to the extension direction of the trough 22, and the extension length of the pusher block 34 is greater than the width of the trough 22. The pusher drive assembly 35 drives the pusher block 34 to move from the first side in the width direction of the trough 22 to the second side in the width direction of the trough 22, that is, the pusher block 34 moves along the Y direction to press the glue sticking device 4 downward. When the pusher block 34 pushes the workpiece 9 to press the glue sticking device 4 downward, the middle part of the pusher block 34 always blocks the discharge end of the trough 22.

[0044] The downward pressure glue sticking device 4 and the material moving device 3 are arranged correspondingly along the width direction of the material trough 22, and the material trough 22 is located between the material moving device 3 and the downward pressure glue sticking device 4. The downward pressure glue sticking device 4 includes a downward pressure mounting seat 41, a supporting plate 42, a lower pressing plate 43, an adhesive tape 44, and a downward pressure driving assembly 45. The supporting plate 42 is arranged on the downward pressure mounting seat 41, and the supporting plate 42 is flush with the material pushing platform, or the end of the material pushing platform away from the material moving device 3 extends into the downward pressure mounting seat 41 and forms the supporting plate 42. The latter is preferably selected in this embodiment. The lower pressing plate 43 and the supporting plate 42 are arranged correspondingly up and down, and the adhesive tape 44 is arranged between the supporting plate 42 and the lower pressing plate 43 along the X direction. The adhesive surface of the adhesive tape 44 is arranged downward and a preset space is set between the adhesive tape 44 and the supporting plate 42. The material pushing block pushes the workpiece 9 to move to the preset space, so that the workpiece 9 is located in the preset space, and the adhesive tape 44 is located between the lower pressing plate 43 and the workpiece 9. The pressing drive assembly 45 is arranged on the pressing mounting seat 41 and connected to the pressing plate 43, and is used to drive the pressing plate 43 to move toward the supporting plate 42 along the Z direction, that is, the pressing plate 43 drives the tape 44 to move toward the workpiece 9, so that the tape 44 is adhered to the surface of the workpiece 9.

[0045] Combination Figure 5 and Figure 6The supporting plate 42 and the lower pressing plate 43 extend toward one end of the cutting device 7 along the X direction, respectively, and the extension length of the two is greater than the total length of the multiple workpieces 9. In this embodiment, it is preferably greater than the total length of six workpieces 9, so that each workpiece 9 located below the lower pressing plate 43 can be pressed down by the lower pressing plate 43 for multiple times to ensure the reliability of the bonding between each workpiece 9 and the adhesive tape 44. The interval between two adjacent workpieces 9 located directly below the lower pressing plate 43 is a preset distance, which can be equal or unequal, and the preset distance can be achieved by controlling the pushing interval time of the pushing block 34 through a pre-set control program. The right ends of the supporting plate 42 and the lower pressing plate 43 are close to the bottom of the cutting device 7, so that the cutting device 7 cuts the adhesive tape 44 at a position close to the ends of the supporting plate 42 and the lower pressing plate 43. After being cut, the adhesive tape 44 still partially protrudes from the right end plates of the supporting plate 42 and the lower pressing plate 43, which is convenient for the adhesive tape pulling device 5 to clamp and pull the next section of the adhesive tape 44.

[0046] A guide block 46 is provided on the support plate 42, and the guide block 46 is flush with the discharge end of the trough 22. The guide block 46 extends along the moving direction of the push block 34, so that when the push block 34 pushes a workpiece 9 to move along the Y direction, the workpiece 9 can always move close to the guide block 46, thereby preventing the workpiece 9 from being offset in the X direction. In the vertical direction, the height of the guide block 46 is less than the thickness of the workpiece 9.

[0047] Combination Figure 8 and Fig. 9 A stop assembly 47 is provided on the side of the support plate 42 away from the push block 34.

The stop mounting seat 471 is set on the downward pressing mounting seat 41, the screw 473 is threadedly connected to the stop mounting seat 471 and extends along the Y direction, and the control handle 472 and the stop block 474 are respectively set at both ends of the screw 473. The end of the stop block 474 away from the screw 473 is located on the support plate 42 and below the tape 44. In the vertical direction, the top wall of the stop block 474 is lower than the top wall of the workpiece 9. The screw 473 is driven to rotate by rotating the control handle 472 to control the stop block 474 to move along the Y direction, so that the distance from the stop block 474 to the center of the width direction of the tape 44 is adjustable, which is convenient for adapting to the downward pressing and gluing operation of workpieces 9 of different lengths, and ensures that each workpiece 9 of different specifications can be bonded to the tape 44 at its own middle position.

[0048] In this embodiment, the width of the adhesive tape 44 is smaller than the length of the workpiece 9, and the adhesive tape 44 is extended along the width direction of the workpiece 9 and pasted on the middle part of the workpiece 9, and the two ends of the workpiece 9 in the length direction are exposed outside the adhesive tape 44. The width of the lower pressing plate 43 is larger than the length of the workpiece 9, and the length of the workpiece 9 is larger than the width of the adhesive tape 44, so that each time the lower pressing plate 43 is pressed down, it can act on the entire width of the adhesive tape 44, which is convenient for ensuring the pasting effect of the adhesive tape 44 and improving the bonding reliability of the adhesive tape 44 and the workpiece 9.

[0049] Combination Figure 3 , Figures 10 to 12 The tape pulling device 5 includes an unwinding assembly 51, a steering wheel 52, a mounting frame 53, a clamping claw moving seat 54 and a clamping claw 55.

The steering wheel 52 is arranged on the pressing mounting seat 41 and is located above the working platform 1, that is, in the Z direction, the height of the lower edge of the steering wheel 52 is higher than the height of the upper edge of the unwinding wheel 511. The steering wheel 52 and the unwinding wheel 511 are both arranged parallel to the Y direction. The middle part of the tape 44 is wound around the surface of the steering wheel 52 to achieve the purpose of steering and tensioning. The second end of the tape 44 passes under the lower pressing plate 43 and extends along the X direction, that is, extends to the tape pulling device 5.

[0050] The mounting frame 53 is set as a gantry frame. The mounting frame 53 is set on the working platform 1 along the X direction. A clamping jaw translation driving assembly 531 is set on the mounting frame 53. The clamping jaw moving seat 54 is set on the mounting frame 53.

The clamping jaw 55 is preferably a pneumatic clamping jaw. In the Z direction, the height of the clamping jaw 55 corresponds to the height of the second end of the tape 44, so that the clamping jaw 55 can clamp the second end of the tape 44 and pull the tape 44 to move along the X direction to the lifting and pasting tape device 6. In order to better clamp the tape 44, a plurality of mutually matching saw teeth are set on both inner sides of the clamping opening of the clamping jaw 55.

At this time, the lower pressure plate 43 is kept in a pressed state, and the carrier frame 65 is driven to rise in the Z direction through the lifting drive assembly 64, so that the tape 44 is bonded to the carrier frame 65; then, the lower pressure plate 43 is kept in a pressed state, and the cutting head 72 moves downward to cut off the tape 44; then, the clamp 55 releases the tape 44, and the tape pasting translation seat 61 drives the carrier frame 65 to move a preset distance along the Y direction to prepare for the next bonding operation. At the same time, the clamp 55 clamps the next section of tape 44, ready to start the next bonding operation.
