Description

Technical Field

[0001] This utility model relates to the field of semiconductors, and in particular to the field of semiconductor product transportation technology, specifically a chip carrier refilling device. Background Technology

[0002] In the chip carrier tray assembly process, the chip trays need to be stacked to a specified number before being transported to the pick and place machine for loading.

[0003] Currently, the chip carrier assembly is assembled in a semi-automatic manner. Technicians need to place the material frames into the designated area of ​​the conveyor belt, and then a robotic arm will stack and assemble the materials. This has the following problems:

[0004] The consistency of the manually placed material frame is poor. When the robotic arm releases the material, the edge of the chip tray will interfere with the inner wall of the material frame. At the same time, because the height of the robotic arm does not change when releasing the material, there is a small probability that the chip tray position at the bottom of the material frame will tilt. When this happens, technicians need to assist in intervening to correct the chip tray position. During the manual intervention process, if the force of the manual movement is not well controlled, the chip may be lifted, resulting in defective parts flowing out in subsequent processes. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a chip carrier disk feeding device to solve the difficulties of the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a chip carrier disk feeding device, comprising:

[0038] This invention proposes a chip carrier disk replenishment device for use in the chip carrier disk assembly and coding process. This invention does not limit the specifications of the chips carried by the chip carrier disk, but the structure of the lifting and receiving module 2 and the chip carrier disk positioning and sorting group 3 is particularly suitable for fully automatic chip carrier disk assembly and coding.

[0039] Overall, the chip carrier replenishment device proposed in this utility model mainly includes: a lifting and receiving module 2 and a chip carrier positioning and sorting group 3. (See also...) Figure 1 It shows the arrangement relationship between the lifting and receiving module 2 and the chip carrier positioning and sorting group 3.

[0040] When using the chip tray replenishment device proposed in this utility model, the stepping cylinder 22 in the lifting and receiving module 2 drives the tray 24 to move upward along the chip tray corner positioning push block 35. After the robotic arm stacks the chip trays on the top of the tray 24, the sliding cylinder 32 in the chip tray positioning and sorting group 3 pushes the chip tray corner positioning push block 35 to abut against the chip tray and correct the chip tray position. Then the stepping cylinder 22 steps downward and retracts, repeating the cycle until the chip tray group with the completed stacking is removed from the tray 24. At the same time, the bottom of the chip tray group contacts the conveyor belt 11 in the double belt conveyor 1. The double belt conveyor 1 transports the chip tray group to the next process. With the lifting and receiving module 2 and the chip tray positioning and sorting group 3, there is no need for manual intervention to stack the chip trays with the material frame, realizing full automation and reducing labor costs.

[0041] The aforementioned double belt conveyor 1 serves as the main carrier for transporting chip trays. It is responsible for transporting the chip trays that have been stacked from the lifting and receiving module to the next process, thereby achieving stable transmission of the chip trays and ensuring the continuity of the entire material collection process.

[0042] The aforementioned lifting and receiving module 2 is bolted to the bottom of the double belt conveyor 1 below the unloading point of the robotic arm. The pallet 24 at the top of the lifting and receiving module 2 is located between the two conveyor belts 11 of the double belt conveyor 1. It is used to receive the chip trays placed from the unloading point of the robotic arm, and to lift and position them. Through the cooperation of the stepping cylinder and the balance bar, the height of the pallet can be precisely adjusted to ensure the flatness of the chip trays. At the same time, it provides an operating basis for the chip tray positioning and sorting group, ensuring that the chip trays remain stable during the lifting process. The lifting and receiving module 2 includes: cylinder mounting plate 21, stepping cylinder 22, pallet 24, linear bearing 25, balance bar 26, stop head 27 and shock absorption spring 28. The cylinder mounting plate 21 is bolted to the bottom of the double belt conveyor 1, providing stable installation support for the stepping cylinder 22 and ensuring that the position of the stepping cylinder 22 is fixed during operation.

[0043] A stepping cylinder 22 is bolted to the center of the bottom of a cylinder mounting plate 21. A cylinder rod 23, passing through the center of the stepping cylinder 22, extends vertically upwards through the cylinder mounting plate 21. The stepping cylinder 22 controls the extension and retraction of the cylinder rod 23 to achieve the vertical lifting and lowering of the tray 24, thereby adjusting the height of the chip tray and coordinating it with the chip tray positioning and sorting group 3 for positioning and stacking operations. The tray 24, bolted to the top of the cylinder rod 23, directly receives the chip tray placed from the robotic arm's unloading point, providing a support platform for the chip tray and ensuring its stability during lifting. Linear bearings 25 are mounted on the cylinder mounting plate around the stepping cylinder 22, providing guidance for the balance bar 26 and ensuring that the balance bar 26 can only move in a straight line. Linear motion ensures the balance of tray 24 during lifting and lowering; the balance bar 26 passes through the center of the linear bearing 25 and is connected to tray 24 at the top by bolts; the function of the balance bar 26 is to maintain the balance of tray 24 during lifting and lowering, prevent tray 24 from tilting, and ensure the stability of chip carrier placement; the stop head 27 is located at the bottom of the balance bar, and when the balance bar 26 descends to the lowest position, the stop head 27 can play a limiting role to prevent the balance bar 26 from descending excessively, protecting the equipment and chip carrier; the top of the shock-absorbing spring 28 is connected to the stop head 27 and is fitted on the outside of the balance bar 26; the shock-absorbing spring 28 plays a buffering role during the descent of the balance bar 26, reducing the impact force generated when the balance bar 26 collides with the stop head 27, protecting the equipment and chip carrier.

[0044] The aforementioned chip tray positioning and sorting assembly 3 is located around the lifting and receiving module 2. It is installed on the outer wall of the dual-belt conveyor 1 away from the drive belt, and performs corner positioning and sorting on the chip trays placed on the pallet, ensuring that the chip trays are neatly placed on the pallet. The chip tray positioning and sorting assembly 3 includes an L-shaped connecting plate 31, a sliding cylinder 32, and chip tray corner positioning push blocks 35. The L-shaped connecting plate 31 is located around the lifting and receiving module and is bolted to the outer wall of the dual-belt conveyor 1 away from the drive belt, providing installation support for the sliding cylinder 32 and ensuring its stable installation.

[0045] The slide cylinder 32 is bolted to the top of the L-shaped connecting plate 31. An L-shaped slide is mounted on the top of the slide cylinder 32. A support plate 34 is bolted to the top of the L-shaped slide 33. The L-shaped slide 33 and the support plate 34 are combined to form a T-shape. The slide cylinder controls the movement of the L-shaped slide 33 to drive the chip tray corner positioning push block to position the chip tray. The chip tray corner positioning push block 35 is bolted to the side of the L-shaped slide and the support plate near the tray 24, forming an L-shape. When the chip tray is placed on the tray 24, the slide cylinder 32 drives the L-shaped slide 33 and the support plate 34 to move, causing the chip tray corner positioning push block 35 to approach the corner of the chip tray and push the chip tray to the correct position, thus achieving the positioning and arrangement of the chip tray.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
