[0002] In the field of semiconductor manufacturing and processing, graphite boats are key components for carrying and transporting semiconductor materials. After welding, especially after welding in a chain welding furnace, they need to be removed for the next step of semiconductor material cleaning. Traditionally, this process may rely on manual operation, that is, the operator needs to manually remove the graphite boat from the welding equipment and then transfer it to other equipment or a workbench for manual loading.

[0003] Manual magazine loading often has speed and accuracy limitations, which can lead to a decrease in overall production line efficiency. Especially in large-scale production, manual loading can become a production bottleneck, impacting overall output. Furthermore, the high risk of human error is a significant issue with manual loading. During the loading process, operators may make mistakes due to fatigue, lack of concentration, or other factors, such as inserting the wrong magazine or damaging the magazine or chip. These errors not only lead to product quality issues but can also damage production equipment, increasing repair and replacement costs. Summary of the Invention

DETAILED DESCRIPTION

[0024] The matrix-type semiconductor lead frame linear fully automatic magazine loading machine of the present application is further described in detail with reference to the accompanying drawings, but is not intended to limit the present application.

[0025] Depend on Figures 1 to 4 As shown, a matrix type semiconductor lead frame linear fully automatic magazine loading machine includes a base plate 1, on which a graphite boat material carrier 9, a lead frame conveying carrier 11 and a magazine carrier 12 are sequentially arranged.

[0026] The graphite boat carrier 9 is provided with a limit rod 901, which is used to limit the graphite boat 13 placed on the graphite boat carrier 9 to facilitate the subsequent transportation of the graphite boat 13. The lead frame conveying carrier 11 is provided with a conveyor belt, which corresponds to the magazine carrier 12 one by one.

[0027] A first horizontal linear module 3 is mounted on the bottom plate 1 , a second vertical linear module 7 is mounted on the sliding portion of the first horizontal linear module 3 , and a lead frame suction plate 8 is connected below the sliding portion of the second vertical linear module 7 .

[0028] A graphite boat unloading platform 10 is provided between the graphite boat carrying platform 9 and the lead frame conveying platform 11 .

[0029] The base plate 1 is provided with a second horizontal linear module 4. Both the first horizontal linear module 3 and the second horizontal linear module 4 are electric linear modules. The first horizontal linear module 3 and the second horizontal linear module 4 are fixed to the conveyor bracket 2 at intervals, and the bottom of the conveyor bracket 2 is fixedly connected to the base plate 1.

[0030] The sliding portion of the second horizontal linear module 4 is provided with a first vertical linear module 5 , and a graphite boat suction plate 6 is connected below the sliding portion of the first vertical linear module 5 .

[0031] The graphite boat suction plate 6 and the lead frame suction plate 8 are both provided with vacuum suction pens, which are connected to the vacuum supply equipment through a hose.

[0032] The first vertical linear module 5 and the second vertical linear module 7 each include a vertically arranged slide rail and a telescopic device connected to the fixed portion of the slide rail. The telescopic device utilizes a pneumatic cylinder, and the end of the telescopic rod of the telescopic device is connected to the graphite boat suction plate 6 and the lead frame suction plate 8 via the slider of the slide rail.

[0033] During operation, the machine is first reset as follows: the second horizontal linear module 4, via the first vertical linear module 5, moves the graphite boat suction plate 6 to the leftmost side of the conveyor 2. Simultaneously, the first horizontal linear module 3, via the second vertical linear module 7, moves the lead frame suction plate 8 to the rightmost side of the conveyor 2. The loaded graphite boat 13 is manually stacked on the graphite boat loading platform 9, and two empty magazines are placed on two side-by-side magazine platforms 12.

[0034] After completing the above steps, the equipment is started. The graphite boat suction plate 6 is driven by the second horizontal linear module 4 to the top of the graphite boat material carrier 9. At this time, the first vertical linear module 5 is turned on, driving the graphite boat suction plate 6 down to the graphite material tray position.

[0035] The graphite boat suction plate 6 is equipped with a sensor and a vacuum buffer suction pen. When the sensor detects contact with the graphite boat 13, the vacuum suction pen is activated. After the graphite boat suction plate 6 absorbs the graphite boat 13, the first vertical linear module 5 drives the graphite boat suction plate 6 back to the upper position.

[0036] The graphite boat material carrier 9 is provided with limiting rods 901 , and the graphite boat 13 is clamped between the limiting rods 901 , which limit the graphite boat 13 to facilitate the subsequent transportation of the graphite boat 13 .

[0037] The graphite boat suction plate 6 moves to the top of the graphite boat unloading platform 10, and the graphite boat suction plate 6 and the graphite boat with the material sucked move downward. The graphite boat unloading platform 10 is provided with a positioning pin 1001, an ejection rod 1002 and a sensor.

[0038] When the positioning pins 1001 align with the graphite boat positioning holes 1301 on the graphite boat 13, the graphite boat 13 continues to move downward. The ejector pins 1002 overcome the friction between the lead frame 14 and the lead frame positioning pins 15, ejecting the lead frame 14. Once the sensor detects that the graphite boat 13 has been placed, the vacuum pen of the graphite boat suction plate 6 is closed, and the graphite boat suction plate 6 returns to its upper position. The graphite boat suction plate 6 then moves to the top of the graphite boat material carrier 9 and waits.

[0039] Afterwards, the lead frame suction plate 8 and its components are driven by the first horizontal linear module 3 to move above the graphite boat unloading platform 10 , that is, above the lead frame 14 loaded on the graphite boat.

[0040] Second vertical linear module 7 drives lead frame suction plate 8 downward to lead frame 14 on the graphite boat. Lead frame suction plate 8 is equipped with a vacuum buffer suction pen. After the vacuum pen is activated to suck lead frame 14, lead frame suction plate 8 and its suctioned lead frame 14 return to the upper position.

[0041] The lead frame suction plate 8 and the sucked lead frame 14 are moved above the lead frame transfer platform 11. The vacuum pen is then turned off, and the lead frame 14 is placed on the lead frame transfer platform 11. The lead frame transfer platform 11 is equipped with a transfer motor and a lead frame conveyor belt. When the transfer motor is activated, the conveyor belt drives the lead frame into the magazine on the magazine platform 12. The magazine then moves upward one space, driven by the magazine platform 12.

[0042] When the graphite boat 13 on the graphite boat unloading platform 10 has completed unloading, the graphite boat suction plate 6 and its components are moved again to above the graphite boat carrying platform 9 for the next round of operation.

[0043] The program is run in a loop. When the magazine on the magazine carrier 12 is full, the program will automatically load the sucked frame lead 14 into the magazine on the magazine carrier 12. When both magazines are full, the program enters a pause state and waits for manual replacement of the two magazines.

[0044] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
