Description

Technical Field

[0001] This utility model relates to automated equipment, and more particularly to an automatic loading and unloading device for IC carrier boards. Background Technology

[0002] With the development of the times, industrial production technology is also developing rapidly, and automated equipment is being used more and more in industrial production. As a key carrier connecting chips and printed circuit boards, IC carrier boards play an important role in electrical connection, physical support and heat dissipation. During the processing of IC carrier boards, they need to be electroplated. During the electroplating process, the IC carrier boards need to be fixed on the hanger. After the electroplating is completed, the IC carrier boards are removed from the hanger. Currently, the above operations are usually done manually for loading and unloading. Manual loading and unloading is not only time-consuming and labor-intensive, but it is also easy to damage the IC carrier boards during the operation. In the industrial field that emphasizes cost reduction and efficiency improvement, it lacks competitiveness and is not conducive to large-scale promotion and industrialized production.

The hanger group 5 located on the front of the base 1 can detach from the base 1 in the vertical direction under the drive of the lifting mechanism 3. In use, the IC carrier board 7 is fixed by the hanger, and then two hanger sets 5 are hung on the base 1. The clamping mechanism 2 clamps the bottom end of the hanger to prevent it from shaking. The opening clamping mechanism 6, driven by the approach mechanism 4, approaches the hanger set 5 located on the front of the base, and then drives the hanger to release the IC carrier board 7, thereby realizing the unloading of the IC carrier board 7. After the IC carrier board 7 is unloaded, a new IC carrier board 7 is replaced. Then, the opening clamping mechanism 6 drives the hanger to clamp the new IC carrier board 7. Then, the hanger set 5 located on the front of the base 1 moves upward and detaches from the base 1 under the drive of the lifting mechanism 3, so as to prevent the hanger set 5 located on the back of the base from obstructing the hanger set 5 located on the back of the base 1. Then, the opening clamping mechanism 6, driven by the approach mechanism 4, moves to the hanger set 5 near the back of the base 1 and loads and unloads the IC carrier board 7 on the hanger set 5, thereby realizing the automated loading and unloading of the IC carrier board 7.

The clamping block 24 can clamp or release the bottom end of the hanger. The first cylinder 21 drives the rack 22 to move up and down, thereby driving the spur gear 25 and the first rotating shaft 23 to rotate. This drives the clamping blocks 24 on the two first rotating shafts 23 to swing in opposite directions. When the two clamping blocks 24 swing in opposite directions, the clamping blocks 24 can clamp the bottom end of the hanger. Conversely, they can release the hanger.

When it is necessary to drive the clamping mechanism 6 closer to the hanger group 5, the second motor 41 drives the two third rotating shafts 43 to rotate through the second T-shaped steering gear 42. The third rotating shafts 43 drive the transmission shaft 44 to rotate, and the transmission shaft 44 drives the lead screw 45 to rotate, thereby driving the clamping mechanism 6 fixed to the lead screw nut 46 to move closer to the hanger group 5 in the horizontal direction.

[0032] Optionally, in this embodiment, each hanging group 5 is provided with three hanging devices.

[0033] Operation process: First, hang the two fixture assemblies 5 with IC carrier boards 7 fixed on them on the base 1. Then, the positioning cylinder 12 pushes the connecting frame 51 so that the side wall of the first positioning block 52 is flush with the side wall of the first fixing seat 11. Next, the first cylinder 21 drives the clamping block 24 to clamp the bottom end of the fixture to fix it. Then, the approach mechanism 4 drives the opening mechanism 6 to approach the fixture assembly 5 located on the front of the base 1. After the opening mechanism 6 drives the spring piece 58 to disengage from the slot, the fixing block 56 releases the IC carrier board 7. At this time, the matching unloading mechanism (such as a robotic arm with a suction cup) removes the IC carrier board 7 and replaces it with a new IC carrier board 7. Then, the second cylinder 62 drives the push The seat 610 presses the spring 58 to reset the spring 58 and fixes the new IC carrier board 7 through the fixing block 56. After all the IC carrier boards 7 on the hanger group 5 on the front of the base 1 have been replaced, the lifting mechanism 3 drives the hanger group 5 to move upward and separate from the base 1. Then the approach mechanism 4 drives the clamping mechanism 6 to approach the hanger group 5 on the back of the base 1 and replace the IC carrier board 7 on the hanger group 5 according to the process of the previous hanger group 5. During the process of replacing the IC carrier board 7 on the hanger group 5 on the back of the base 1, the hanger group 5 that is lifted by the lifting mechanism 3 can be removed. This process is repeated to realize the automated loading and unloading of IC carrier boards 7.
