Description

Technical Field

[0001] This utility model relates to the field of chip loading machine technology, specifically a chip loading machine. Background Technology

[0002] Die bonding is the process of attaching a chip to a substrate using die bond adhesive, also known as die bonding or die mounting. Die bonding involves two processes: 1. Eutectic bonding: This process uses the temperature of the equipment to melt the metal on the back of the chip, then bonds the chip to the base island position on the substrate. The base island position on the substrate also has a silver plating layer to ensure adhesion. 2. Dispensing: This process involves applying adhesive, also known as silver paste, to the base island position on the substrate to enhance adhesion. This is essentially an additional step on top of the eutectic bonding process. After dispensing, a pin on the bottom of the chip lifts it up, and then a nozzle picks it up and applies it to the adhesive on the substrate island. Currently, chip bonding is usually done by a single robotic arm continuously picking up the chips and placing them on the substrate island. However, because it requires picking up chips one by one, the efficiency of chip bonding is reduced. Furthermore, due to the separate setup of the conveyor, the die bonder and the conveyor need to be adjusted to coordinate, resulting in insufficient linkage. Therefore, we have proposed a chip bonding machine. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 6 A chip mounting machine includes a main frame 1, with conveying devices fixedly connected to both sides of the main frame 1. A support column 2 is fixedly connected to the top of the conveying devices, and a top plate 3 is fixedly connected to the top of the support column 2. A suction cup mechanism is installed on the main frame 1. The two conveying devices can respectively convey the chip and the substrate frame. A motor 4 is fixedly connected to the top of the main frame 1, and a central gear 9 is fixedly connected to the output shaft of the motor 4. Driven by the motor 4, the central gear 9 can rotate. The motor 4 is existing technology and will not be described in detail here. A first gear 11 and two second gears 12, connected to the main frame 1 by pins, mesh with the outer side of the central gear 9. Driven by the central gear 9, the chip and substrate frame 3 are respectively conveyed to the main frame 1. The first gear 11 and the second gear 12 are rotatable. The outer ring plate 8 is meshed with the outer side of the first gear 11. Driven by the first gear 11, the outer ring plate 8 can rotate. The suction cup mechanism is installed on the outer ring plate 8. Driven by the outer ring plate 8, the suction cup mechanism can perform circumferential motion. A limiting ring plate 17 that can drive the suction cup mechanism to move downward is fixedly connected to the outer side of the main frame 1. At the same time, a linkage mechanism is connected between the second gear 12 and the conveying device. Through the linkage mechanism, the rotation of the outer ring plate 8 can be transmitted with the conveying device, so that they can cooperate, making it more convenient to use and requiring only one drive source, thus making it more energy-efficient.

[0021] Please see Figures 1 to 6The suction cup mechanism includes a suction cup mechanism body 18, a spring 19, a spring plate 20, and a protrusion 21. The top of the suction cup mechanism body 18 is slidably sleeved with the outer ring plate 8, allowing the suction cup mechanism body 18 to slide vertically relative to the outer ring plate 8. The spring plate 20 is slidably sleeved on the suction cup mechanism body 18, allowing the spring plate 20 to slide vertically relative to the suction cup mechanism body 18. The top of the spring plate 20 is fixedly connected to the spring 19, and the top of the spring 19 is fixed to the outer side of the top of the suction cup mechanism body 18. Under the action of the spring force of the spring 19, the suction cup mechanism body 18 can be pushed to return to its original position, thereby causing the protrusion 21 to return to its original position. The bottom end of the suction cup mechanism body 18 passes through the middle of the limiting ring plate 17 and is fixed to the protrusion 21. The top of the protrusion 21 is arc-shaped, allowing the protrusion 21 to pass smoothly through the sinking block 22.

[0022] Please see Figures 1 to 6 The limiting ring plate 17 has a hollow annular shape in the middle, and a sinking block 22 with an arc-shaped bottom surface is fixedly connected to the limiting ring plate 17 directly above the conveying device, so that the protrusion 21 can pass through more smoothly. Under the action of the sinking block 22, the protrusion 21 can move down to pick up and put in the chip. The top of the protrusion 21 abuts against the bottom of the limiting ring plate 17, and the bottom of the spring plate 20 abuts against the top of the limiting ring plate 17, so that the spring plate 20 can always abut against the limiting ring plate 17 to drive the suction cup mechanism body 18 to reset.

[0023] Please see Figures 1 to 5 The conveying device includes a conveyor frame 5, a placement trough 6, toothed rollers 10, and a toothed belt 13. The conveyor frame 5 is fixedly installed on both sides of the main frame 1. Multiple toothed rollers 10 are connected inside the conveyor frame 5 by shaft pins, so that the toothed rollers 10 can rotate in a fixed position on the conveyor frame 5. The outer sides of the toothed rollers 10 are engaged with a toothed belt 13, which in turn enables the toothed rollers 10 to drive the toothed belt 13 to rotate. The outer side of the toothed belt 13 is provided with a separate placement base island frame and a chip placement trough 6, which enables the base island frame and the chip to be transported stably.

[0024] Please see Figures 1 to 5The linkage mechanism includes a transmission rod 7, a third gear 14, a fourth gear 15, and a linkage rod 16. The bottom of the second gear 12 is fixedly connected to the transmission rod 7. Driven by the second gear 12, the transmission rod 7 can rotate. The bottom end of the transmission rod 7 is fixedly connected to the third gear 14. Driven by the transmission rod 7, the third gear 14 can rotate. The bottom of the third gear 14 is engaged with the fourth gear 15. Driven by the third gear 14, the fourth gear 15 can rotate. One side of the fourth gear 15 is fixedly connected to the linkage rod 16, which extends into the main frame 1. Driven by the fourth gear 15, the linkage rod 16 can rotate. One end of the linkage rod 16 is fixed to the toothed roller 10 in the middle. Driven by the linkage rod 16, the toothed roller 10 can rotate.

[0025] In summary, when this chip loading machine is in use, the central gear 9 rotates under the drive of the output shaft of the motor 4. Under the drive of the central gear 9, the first gear 11 rotates, which in turn rotates the outer ring plate 8, causing the suction cup mechanism on it to rotate. When the protrusion 21 rotates to the sinking block 22, the sinking block 22 causes the protrusion 21 to move down and pick up the chip from one conveyor. When it moves to another conveyor, the sinking block 22 causes the protrusion 21 to move down again, allowing the chip to be placed on the base island frame. Under the drive of the central gear 9, the second gear 12 rotates, which in turn drives the transmission rod 7 to rotate, which in turn drives the third gear 14 to rotate. Under the drive of the third gear 14, the fourth gear 15 drives the linkage rod 16 to rotate, which in turn causes the toothed roller 10 to rotate, allowing the two toothed belts 13 to transport the chip and the base island frame.
