Description

Technical Field

[0001] This invention belongs to the field of integrated circuit processing, and specifically discloses a chip mounting device for integrated circuit processing. Background Technology

[0002] In the processing and manufacturing of integrated circuits, surface mount technology is the core link of modern electronic assembly. As a key piece of equipment on the SMT production line, the placement device is responsible for placing miniature electronic components onto the predetermined positions on the circuit board at high speed and with high precision. Its standard process includes a series of automated operations such as conveying the circuit board by the conveyor belt, performing visual positioning, picking up and placing components. The positioning accuracy and stability of the entire system are the key to ensuring the yield of the final product.

[0003] However, when the object to be placed is a circular integrated circuit board, traditional placement equipment faces severe challenges. The primary problem lies in positioning and fixing. Circular circuit boards lack effective reference edges for guidance and limitation on the conveyor belt, making them prone to offset and rotation. This results in the inability to accurately center them at the placement station, causing initial positioning errors. At the same time, during the placement process, when the placement head presses down, uneven support or unstable force can cause the edges of the circuit board to lift. This instability directly causes the component to shift or tilt at the moment of contact with the pad, resulting in skewed placement and seriously affecting the product's placement yield and quality.

The anti-slip sleeve is made of silicone material. The two adjusting rollers are located on both sides of the outer wall of one of the circuit board workpieces.

[0011] Preferably, there are two sets of clamping mechanisms, with each clamping mechanism located above the two conveyor belts. Each clamping mechanism includes a rotating block, and there are two sets of rotating blocks. One side of each rotating block is connected to one side of an L-shaped plate. A rotating rod is rotatably connected to the lower end of each rotating block. One end of each rotating rod is connected to a connecting block. A cylinder is connected to the middle of the upper end of each connecting block. The output ends of each cylinder extend through to the lower end of the two connecting blocks.

[0012] Preferably, both cylinders are connected to a pressing block at their lower ends, and the lower ends of the two pressing blocks are in contact with the upper end of the circuit board workpiece.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The centering mechanism uses a combination of adjusting rods and adjusting rollers. Utilizing the self-centering principle, it reliably eliminates the offset and rotation of the circular plate during transport. At the same time, the displacement mechanism moves synchronously with the conveyor belt, ensuring that there is no secondary displacement during the movement of the circuit board workpiece from the centering station to the placement station. This allows the placement equipment to always operate on the precisely calibrated workpiece, fundamentally eliminating placement skew caused by positioning errors.

[0016] The displacement mechanism allows the centering mechanism, clamping mechanism, and side stabilizing mechanism to move with the circuit board workpiece to the placement station, ensuring the stability of the circuit board workpiece during the placement process.

[0017] Through the combined action of the clamping mechanism and the side stabilizing mechanism, the circuit board workpiece is clamped from above and supported from the side in all directions. The clamping mechanism applies controllable flexible pressure from above, which suppresses the warping of the circuit board workpiece caused by its own stress or mounting impact. Meanwhile, the arc-shaped L-shaped support block provides support from the side and the lower edge at the same time, which enhances the deformation resistance and overall rigidity of the circuit board workpiece at the moment of mounting, ensuring that the mounting surface always remains flat and effectively avoiding defects such as mounting skew.

The vision inspection frame 11 can identify the position of the circuit board workpiece 12. The displacement mechanism is responsible for carrying and accurately transferring the centering mechanism, the clamping mechanism, and the side stabilizing mechanism. The L-shaped plate 16 is used to install the centering, clamping, and side stabilizing mechanisms. The centering mechanism realizes the automatic centering and position correction of the circular circuit board workpiece 12. The clamping mechanism applies controllable downward pressure to prevent the circuit board workpiece 12 from tilting or shifting during processing. The side stabilizing mechanism provides auxiliary support and clamping from the side to enhance the overall stability of the circuit board workpiece 12 during the placement process. The vertical slide rail 2, the vertical slider 3, the horizontal slide rail 4, and the adjusting slider can be used to drive the chip placement equipment 5 to achieve precise movement.

[0023] like Figures 1-3As shown: There are four sets of support blocks 7. The lower ends of multiple support blocks 7 are connected to the upper sides of the machine housing 1 respectively. One end of multiple hydraulic cylinders 8 extends through to one side of the support block 7. There are four sets of hydraulic cylinders 8. The two moving plates 9 slide above the machine housing 1. The two moving plates 9 slide below the two vertical slide rails 2. The vision inspection frame 11 is located above the two conveyor belts 10. The upper end of the machine housing 1 is equipped with a placement rack 6 on the side corresponding to the patching device 5. There are two sets of moving slide rails 14. One side of the two moving slide rails 14 is connected to one side of the inner wall of the two mounting slots 13 respectively. There are two sets of centering mechanisms. The two centering mechanisms are located above the two conveyor belts 10 respectively. Four sets of support blocks 7 are symmetrically distributed on both sides of the chassis 1 to provide balanced support, and the overall conveying mechanism is fixed by connecting with the chassis 1. Four sets of hydraulic cylinders 8 are symmetrically arranged to adjust the spacing of the moving plates 9.

The placement frame 6 is set on the side of the placement equipment 5 for component supply. Two sets of moving slide rails 14 are fixed in two mounting slots 13 respectively to provide a guiding foundation for the displacement mechanism. The moving slide rails 14 are electrically controlled slide rails. Two sets of centering mechanisms are set above the two conveyor belts 10 respectively to realize the centering operation of the circuit board workpiece 12.

[0024] like Figures 4-7 As shown: The centering mechanism includes a drive motor 17. The upper end of the drive motor 17 is connected to the lower end of the L-shaped plate 16. A rotating rod 18 is connected to the lower end of the L-shaped plate 16 on the side corresponding to the drive motor 17. A first rotating gear 19 is connected to the outer wall of the output end of the drive motor 17. A second rotating gear 20 is meshed with one side of the first rotating gear 19. The inner wall of the second rotating gear 20 is connected to the outer wall of the rotating rod 18. Adjusting rods 21 are connected to the lower ends of the first rotating gear 19 and the second rotating gear 20. The two adjusting rods 21 are V-shaped. A first miniature electric telescopic rod 22 is connected to one side of the upper end of the two adjusting rods 21. The lower ends of the two first miniature electric telescopic rods 22 extend through to the outer wall of the two adjusting rods 21. Adjusting rollers 23 are connected to the lower ends of the two first miniature electric telescopic rods 22. Anti-slip sleeves are provided on the outer walls of the adjusting rollers 23. The anti-slip sleeves are made of silicone material. The two adjusting rollers 23 are located on both sides of the outer wall of one of the circuit board workpieces 12. The drive motor 17 transmits power synchronously to the two adjusting rods 21 through the meshing of the first rotating gear 19 and the second rotating gear 20, thereby driving the two adjusting rods 21 to perform opening and closing actions. The first micro electric telescopic rod 22 can adjust the lifting and lowering of the roller 23, so that it can be raised to avoid obstacles during non-working periods and lowered to contact the edge of the circuit board workpiece 12 during working periods. The adjusting roller 23, which is covered with a silicone anti-slip sleeve, moves forward and backward synchronously from four directions under the drive of the adjusting rod 21. Using the principle of automatic centering, it can achieve fast and accurate centering of the circular circuit board workpiece 12, and the entire process effectively protects the surface of the circuit board workpiece 12 through flexible contact.

[0025] like Figure 7 As shown: There are two sets of clamping mechanisms, which are located above the two conveyor belts 10 respectively. Each clamping mechanism includes a rotating block 24. There are two sets of rotating blocks 24. One side of each rotating block 24 is connected to one side of the L-shaped plate 16. The lower end of each rotating block 24 is rotatably connected to a rotating rod 25. One end of each rotating rod 25 is connected to a connecting block 26. The upper middle part of each connecting block 26 is connected to a cylinder 27. The output ends of each cylinder 27 extend through to the lower end of each connecting block 26. The lower end of each cylinder 27 is connected to a pressing block 28. The lower end of each pressing block 28 contacts the upper end of the circuit board workpiece 12. The lower end of each pressing block 28 is made of a flexible material. One middle part of each rotating rod 25 is rotatably connected to an adjusting electric telescopic rod 29. One end of each adjusting electric telescopic rod 29 is rotatably connected to one side of the L-shaped plate 16. Two sets of clamping mechanisms are hinged to one side of the L-shaped plate 16 via rotating blocks 24, forming a swingable clamping arm. The angle position of the rotating rod 25 is changed by adjusting the electric telescopic rod 29. When the rotating rod 25 is adjusted to be in position above the circuit board workpiece 12, the cylinder 27 pushes the lower pressure block 28 to perform the clamping action. The lower pressure block 28 clamps the circuit board workpiece 12, ensuring the safety and non-damage of the clamping process of the circuit board workpiece 12. The clamping function can be effectively completed without interfering with the conveying of the circuit board workpiece 12.

[0026] like Figures 8-9As shown: There are two sets of side stabilizing mechanisms. Each side stabilizing mechanism includes two sets of fixing blocks 30. One side of each of the two fixing blocks 30 is connected to one side of each of the two L-shaped plates 16. The upper middle of each of the two fixing blocks 30 is connected to a second miniature electric telescopic rod 31. The lower ends of the two second miniature electric telescopic rods 31 extend through to the lower ends of the two fixing blocks 30. The lower ends of the two second miniature electric telescopic rods 31 are connected to lifting blocks 32. The middle of one side of each of the two lifting blocks 32 is connected to a diagonal rod 33. A connecting plate 34 is connected between the two diagonal rods 33. The lower part of one side of the connecting plate 34 is connected to... Two miniature electric telescopic rods 35 are connected. One end of each of the two miniature electric telescopic rods 35 extends through to one side of the connecting plate 34. One end of each miniature electric telescopic rod 35 is connected to a support block 36. The support block 36 is located on one side of one of the circuit board workpieces 12. The cross-sectional shape of the support block 36 is L-shaped. The overall shape of the support block 36 is arc-shaped. The overall shape of the support block 36 is in contact with one side of the outer wall of the circuit board workpiece 12. A buffer pad is connected to one side of the support block 36. The buffer pad is L-shaped. One side of the buffer pad is in contact with one side of the circuit board workpiece 12. The side stabilizing mechanism is installed on one side of the L-shaped plate 16 via the fixing block 30. The second micro electric telescopic rod 31 controls the lifting and lowering of the entire clamping assembly, realizing the switching between the working position and the avoidance position. The inclined rod 33 and the connecting plate 34 form a cantilever frame located on the side of the circuit board workpiece 12. The third micro electric telescopic rod 35 controls the horizontal movement of the arc-shaped L-shaped support block 36. When the mechanism is working, the support block 36 moves forward under horizontal drive, and its L-shaped inner surface simultaneously fits the side and lower edge of the circuit board workpiece 12, thereby realizing the lateral limiting and bottom lifting of the circular circuit board workpiece 12, forming a stable and reliable lateral constraint.

[0027] Working principle: At the beginning of the device, the movable slider 15, the L-shaped plate 16 and the centering mechanism, the clamping mechanism and the side stabilizing mechanism installed on it are located in the initial position on one side of the patch device 5.

[0028] The hydraulic cylinder 8 drives the moving plate 9 to adjust the spacing between the two conveyor belts 10 to accommodate circular circuit board workpieces 12 of different sizes. Subsequently, the conveyor belts 10 transport the circuit board workpieces 12 forward.

[0029] When the circuit board workpiece 12 is conveyed to the underside of the vision inspection frame 11, the vision system identifies it. Once the workpiece is detected to be in place, the conveyor belt 10 immediately stops running, causing the workpiece to stop between the two moving sliders 15.

[0030] Subsequently, the two centering mechanisms begin to operate. First, the two first micro electric telescopic rods 22 move synchronously, driving the adjusting rollers 23 at their lower ends to move downwards, so that the adjusting rollers 23 are located at the edge of the circuit board workpiece 12 and ensure that they can contact the outer surface of the circuit board workpiece 12. Then, the drive motor 17 starts, driving the first rotating gear 19 to rotate, and the second rotating gear 20 meshing with it rotates in the opposite direction, thereby driving the two V-shaped adjusting rods 21 to close synchronously. Through the guiding principle of the V-shaped structure, the four adjusting rollers 23 contact and guide the circular circuit board workpiece 12 from different directions, automatically correcting and forcing the center of the circular circuit board workpiece 12 to be aligned, thus completing the precise positioning.

[0031] After the circuit board workpiece 12 is aligned, the electric telescopic rod 29 is extended and retracted, pushing the rotating rod 25 to rotate around the rotating block 24, and the lower pressure block 28 is precisely swung above the circuit board workpiece 12. Then, the cylinder 27 drives the lower pressure block 28 to move downward, using the flexible material at its lower end to press the circuit board workpiece 12 firmly onto the surface of the conveyor belt 10, effectively suppressing any possible warping of the circuit board workpiece 12.

[0032] While the clamping mechanism is working, the side stabilizing mechanism is activated. The second micro electric telescopic rod 31 drives the lifting block 32 and the connected support block 36 to descend to an appropriate height. Then, the third micro electric telescopic rod 35 pushes the support block 36, which has an arc-shaped L-shaped structure, forward horizontally, so that the inner buffer pad tightly fits and supports the side and lower edge of the circuit board workpiece 12, thereby achieving lateral auxiliary support and clamping.

[0033] After the above fixing is completed, the two conveyor belts 10 are started again, driving the circuit board workpiece 12 to move. The electrically controlled moving slide rail 14 is started, precisely driving the moving slider 15, which drives the circuit board workpiece 12, which has been firmly fixed, and the entire centering, pressing and stabilizing mechanism to move smoothly. The circuit board workpiece 12, the centering mechanism, the pressing mechanism and the side stabilizing mechanism all maintain synchronous movement until they reach the preset position directly below the placement equipment 5. The moving slide rail 14 and the conveyor belt 10 stop synchronously.

[0034] Driven by the vertical slide rail 2, the vertical slider 3, the horizontal slide rail 4, and the adjusting slider, the placement equipment 5 performs precise positioning, picks up the component from the placement rack 6, and performs placement operation on the circuit board workpiece 12, which is already in an absolutely stable state.

[0035] After the patch is applied, the third micro electric telescopic rod 35 retracts, pulling the support block 36 backward horizontally; the second micro electric telescopic rod 31 retracts, lifting the support block 36 to a safe height; the cylinder 27 drives the lower pressure block 28 to retract upward; the adjusting electric telescopic rod 29 moves, swinging the rotating rod 25 back to its initial position; the drive motor 17 reverses, driving the two adjusting rods 21 to open synchronously, causing the adjusting roller 23 to move outward; subsequently, the first micro electric telescopic rod 22 retracts, lifting the adjusting roller 23 upward, completely detaching it from the circuit board workpiece 12 and returning it to its initial height.

[0036] Each stabilizing mechanism resets in sequence and retracts upward to move away from the circuit board workpiece 12. Then, the electrically controlled moving slide rail 14 drives the moving slider 15 to move the whole to the initial position. The conveyor belt 10 restarts, sends out the circuit board workpiece 12 that has been mounted, and begins the next work cycle.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
