Description

Technical Field

[0001] The utility model relates to the technical field of IC carrier plate processing equipment, and more specifically, to a carrier plate in-and-out box handling mechanism. Background Art

[0002] With the rapid development of new packaging technologies such as BGA, CSP, and FC, higher requirements are put forward for the line width, line pitch, through holes, etc. of packaging substrates. The previous mid- to low-end wire bonding type carrier plates have been gradually replaced by high-end flip chip type substrates, and thus developed from wire bonding to the direct-through solder ball method. The solder ball diameter has also developed from more than 100 microns to the current 40 - 60 microns, and the ball pitch is 60 - 80 microns with high precision. In order to ensure reliable conduction of each IO between the chip and the carrier plate during packaging and prevent mutual connection between adjacent IOs, higher requirements are placed on the overall flatness and height of the solder balls on the chip and the carrier plate after ball implantation.

[0003] Among them, existing solder ball leveling equipment generally uses a manipulator for feeding. The manipulator can transfer the carrier plate into the flattening mechanism, but the solder ball leveling equipment cannot use a magazine type cartridge for feeding, and cannot take out and feed the carrier plates stored in the magazine type cartridge.

[0025] As Figure 2 and Figure 3 shown, the gripper movement adjustment device 37 can be mounted on the transfer plate movement driving device 35 through the gripper mounting bracket 38. The gripper movement adjustment device 37 is connected to the gripper 36 and can drive it to move horizontally.

The limiting plate spacing adjustment device 39 is mounted on the Z-axis lifting seat 32. The limiting plate spacing adjustment device 39 is in transmission connection with the two guiding and limiting plates 310 and can drive the two guiding and limiting plates 310 to move away from or close to each other.

[0028] Specifically, the limiting plate spacing adjustment device 39 can include a limiting plate adjustment bracket 391, a limiting plate adjustment driving motor 392, a limiting plate adjustment driving lead screw 393, a limiting plate adjustment lead screw mounting seat 394, a first limiting plate adjustment nut seat 395, a second limiting plate adjustment nut seat 396, a limiting plate adjustment synchronous pulley 397, and a limiting plate adjustment synchronous belt 398. The limiting plate adjustment bracket 391 is mounted on the Z-axis lifting seat 32. The limiting plate adjustment driving motor 392 is mounted on one side surface of the limiting plate adjustment bracket 391. The limiting plate adjustment driving lead screw 393 is mounted on one end surface of the limiting plate adjustment bracket 391 through the limiting plate adjustment lead screw mounting seat 394 and is perpendicular to the moving direction of the transfer plate 34 for entry and exit. The limiting plate adjustment driving motor 392 is in transmission connection with the limiting plate adjustment driving lead screw 393 through the limiting plate adjustment synchronous pulley 397 and the limiting plate adjustment synchronous belt 398 and can drive it to rotate.

The limiting plate adjustment driving motor 392 can drive the two guiding and limiting plates 310 to move through the limiting plate adjustment driving lead screw 393 to achieve the width adjustment function, so that the carrier plate in-and-out box handling mechanism 3 can adapt to more carrier plates with different widths.

[0029] To make the movement of the guiding and limiting plate 310 smooth and stable, the two guiding and limiting plates 310 can be respectively slidably connected to the limiting plate guide 312 installed at the top of the limiting plate adjusting bracket 391 through the limiting plate sliders 311.

[0030] Preferably, as Figure 4 shown, on the outer sides of the head ends of the two guiding and limiting plates 310, there are respectively provided limiting plate lifting driving devices 313.

Among them, the limiting plate lifting driving device 313 can preferably be set as a limiting plate lifting cylinder. The material taking and limiting plate 314 can limit the carrier plate in the vertical direction.

[0031] The working principle of the present utility model is as follows:

[0032] When taking the plate, the moving driving device 35 of the loading and unloading plate can drive the loading and unloading plate 34 to move into the inner part of the upper-layer magazine (square layered magazine) to pull out the specified carrier plate in the direction of the gripper 36. Then, the gripper moving and adjusting device 37 drives the gripper 36 to move and grip the carrier plate. The moving driving device 35 of the loading and unloading plate drives the loading and unloading plate 34 to reset. When a manipulator moves over to take the material later, the gripper 36 releases the carrier plate, and the gripper moving and adjusting device 37 drives the gripper 36 to reset. Subsequently, the manipulator grips and takes away the carrier plate.

[0033] When the manipulator conveys the processed carrier plate back, the gripper moving and adjusting device 37 drives the gripper 36 to move and grip the carrier plate. The moving driving device 35 of the loading and unloading plate drives the loading and unloading plate 34 to move towards the gripper 36. Then, the Z-axis lifting driving module 31 drives the loading and unloading plate 34 and the carrier plate placed on the loading and unloading plate 34 to move downward until it moves to the entrance of the lower-layer magazine. After moving in place, the gripper 36 releases the carrier plate, and the moving driving device 35 of the loading and unloading plate drives the loading and unloading plate 34 to convey the carrier plate into the inner part of the magazine.

[0034] In summary, the present utility model can stably take out the carrier plate from the inner part of the magazine, and can also smoothly convey the processed carrier plate to the magazine. Its operation is stable and reliable, which can prevent the carrier plate from falling, and has an online automatic width-adjusting transportation function, and can be applicable to carrier plate products with different plate widths.

[0035] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
