[0002] In the field of semiconductor manufacturing and related precision electronic component production, silver film as a core functional material, its processing procedures such as mounting have very high requirements on production precision, efficiency and process stability. Silver film fixture as a key carrier for carrying silver film for processing, its flow efficiency and positioning accuracy in the production equipment directly determine the beat speed and product yield of the whole production line.

[0003] At present, the traditional production line in the industry still widely relies on manual operation mode in the feeding and discharging and inter-station flow of silver film fixture. The operator needs to manually carry the silver film fixture from the storage area to the working position of the processing equipment, and then manually transfer the fixture from the working position to the recycling area after the silver film processing is completed. However, the manual operation mode has the following defects: Firstly, the efficiency of manual carrying and placing is low, the time consumption of single operation is long, and it is difficult to maintain a stable operation rhythm, which cannot meet the demand of modern semiconductor production for high beat and high capacity. Secondly, the consistency of manual operation is poor, and the placing force and position deviation of different operators or the same operator at different times are different, which leads to low positioning accuracy of silver film fixture in the working position, and easily causes quality problems such as silver film mounting deviation, which seriously affects the product yield. Thirdly, too many manual intervention links not only increase the labor cost, but also increase the risk of fixture damage or silver film pollution caused by human error (such as fixture collision and misplacement), which further reduces the stability of the production process.

[0032] AsFigures 6-8 As shown, the automatic storage mechanism 4 includes a second cylinder 41 mounted on the bottom of the rack 1, the telescopic end of the second cylinder 41 is mounted with a second support plate 42, the rack 1 on both sides of the second support plate 42 is mounted with a limiting mechanism 43 for one-way lifting of the product and a storage frame for storing the finished product, when the jig is transported to the storage position, the conveying belt 21 transports the finished jig to above the second support plate 42, the second cylinder 41 is extended when the cylinder is lifted, driving the second support plate 42 to rise, lifting the jig upward, when the jig contacts the limiting mechanism 43, the wedge block 433 of the limiting mechanism 43 rotates around the hinge point (compressing the second return spring 434), smoothly passing upward, when the jig is one-way limited, when the jig rises to the specified height of the storage frame, the second cylinder 41 is retracted, the second support plate 42 is lowered, at this time the wedge block 433 of the limiting mechanism 43 is returned under the action of the second return spring 434, the flat side of the sharp part 435 of the wedge block 433 abuts against the bottom of the jig, preventing the jig from falling back, realizing the orderly stacking and storage of the jig, avoiding the chaotic accumulation of the jig at the storage position, without manual real-time removal of the finished product, prolonging the single production cycle and improving the continuous operation efficiency of the production line.

[0033] The limiting mechanism 43 includes a mounting seat 431 fixed on both sides of the rack 1, U-shaped blocks 432 are fixed at both ends of the mounting seat 431, wedge blocks 433 are arranged in the U-shaped blocks 432, the wedge blocks 433 have sharp parts 435 for providing supporting force to the product at one end, the other end of the wedge blocks 433 is hinged with the U-shaped blocks 432, and the hinge of the wedge blocks 433 and the U-shaped blocks 432 is mounted with second return springs 434, when the jig rises, the sharp part 435 of the wedge block 433 is pressed by the bottom of the jig, the wedge block 433 rotates around the hinge point, and the second return spring 434 is compressed, so that the jig can smoothly pass upward; After the jig is lifted into position, the second cylinder 41 drives the second support plate 42 to descend, the jig loses support and has a falling tendency, at this time the second return spring 434 rebounds, driving the wedge block 433 to return to normal, the sharp part 435 abuts against the bottom of the jig, forming one-way locking, fixing the jig in the storage frame, the sharp part 435 is designed to improve the contact stability with the jig, ensuring reliable limiting and avoiding the jig from falling back, the second return spring 434 drives the wedge block 433 to automatically return to normal without additional power, simplifying the structure and reducing energy consumption.

[0034] As Figures 3-5As shown, the automatic feeding mechanism 5 includes a gripper 51 with an automatic rebound effect and a cylinder lifting mechanism 52 for automatically clamping and releasing the product by triggering the gripper 51. The cylinder lifting mechanism 52 is installed at the inner bottom of the frame 1, and the gripper 51 is symmetrically installed on both sides of the frame 1. A guide frame 53 for storing products to be processed is provided on the frame 1 at the gripper 51. Through the cooperation of the cylinder lifting mechanism 52 and the gripper 51, the silver film fixture is ensured to fall in an orderly manner in a single piece, improving the continuity of fixture falling and effectively solving the problems of transmission channel jamming and fixture stacking damage caused by multiple fixtures falling at the same time in manual placement or simple mechanisms.

[0035] The gripper 51 includes a U-shaped plate 511, with fixing plates 512 fixed to the inner walls of both ends of the U-shaped plate 511. A clamping plate 513 is hinged between the two fixing plates 512. A first return spring is installed at the hinge point between the clamping plate 513 and the fixing plate 512, allowing the clamping plate 513 to tilt at an angle around the hinge point within the fixed base. The gripper 51 uses the U-shaped plate 511 as its mounting base. The fixing plates 512 are fixed to the inner walls of the U-shaped plate 511, and the clamping plate 513 is hinged between the two fixing plates 512, with the first return spring installed at the hinge point. The clamping plate 513 can tilt around the hinge point. Automatic reset is achieved through spring force. When the cylinder lifting mechanism 52 rises, the pusher acts on the clamping plate 513, causing it to tilt around the hinge point, and the gripper 51 opens, allowing the bottom fixture to fall. When the cylinder lifting mechanism 52 descends, the pusher disengages from the clamping plate 513, and the first reset spring drives the clamping plate 513 back to the center, re-engaging the upper fixture, allowing only a single fixture to fall to the conveyor belt 21. The first reset spring ensures that the gripper 51 has an automatic rebound limit function, avoiding transmission jamming or fixture damage caused by multiple fixtures falling at the same time, and ensuring the continuity and reliability of fixture feeding.

[0036] The clamping plate 513 includes a connecting plate 5131. One end of the connecting plate 5131 is integrally formed with a boss 5133. The boss 5133 has an inclined surface on the side near the cylinder lifting mechanism 52. The two ends of the boss 5133 are provided with mounting holes for hinge connection. The other end of the connecting plate 5131 is integrally formed with two flanges 5132 for supporting the product. The flanges 5132 are perpendicular to the connecting plate 5131, forming a fixture support surface. When the roller 525 of the cylinder lifting mechanism 52 rises, the roller 525 slides along the inclined surface, which can smoothly push the clamping plate 513 to tilt, reducing mechanical jamming. The flanges 5132 form a bottom support for the fixture in the guide frame 53, preventing the fixture from shifting during storage. At the same time, it ensures that after the single fixture is separated, it can fall accurately into the support area of ​​the flanges 5132 and then smoothly transition to the conveyor belt 21.

[0037] The cylinder lifting mechanism 52 includes a first cylinder 521 installed at the bottom of the frame 1. A first support plate 522 is fixed to the telescopic end of the first cylinder 521. Pushing members are fixed on both sides of the first support plate 522 for tilting the clamping plate 513 during the lifting process. The first cylinder 521 drives the first support plate 522 to lift and lower. During lifting, the first support plate 522 drives the pushing members to rise. The pushing members act on the boss 5133, causing the gripper 51 to open. At the same time, the first support plate 522 receives the falling single piece of fixture. During descent, the first support plate 522 drives the pushing members to descend. The gripper 51 closes under the action of the return spring. The fixture on the first support plate 522 descends with the support plate to the conveyor belt 21. The cylinder drive has the characteristics of fast response speed and stable power, ensuring that the lifting and lowering actions are precise and controllable. The first support plate 522 serves as a transition carrier for the fixture, preventing the fixture from falling directly from the guide frame 53 to the conveyor belt 21 and causing impact, thus protecting the fixture and the silver film from damage.

[0038] The pushing component includes a connecting rod 523, the upper end of which is fixed to the side wall of the first support plate 522, and the lower end of which is fixed to a mounting plate 524. The connecting rod 523 and the mounting plate 524 form an L-shaped structure. A rolling wheel 525 is rotatably mounted on the mounting plate 524. When the first support plate 522 rises, the rolling wheel 525 rises with the mounting plate 524 and rolls along the inclined surface of the boss 5133 of the clamping plate 513, converting sliding friction into rolling friction and smoothly pushing the clamping plate 513 to tilt. When descending, the rolling wheel 525 rolls in the opposite direction along the inclined surface, without interfering with the reset of the clamping plate 513, greatly reducing the frictional loss between the pushing component and the boss 5133 of the clamping plate 513, reducing mechanical noise, improving the smoothness of the opening and closing of the gripper 51, and further ensuring the stability of the unloading action and the life of the component.

[0039] The first support plate 522 and the second support plate 42 both include a support frame 421 for fixing to the telescopic end of the cylinder. A bearing plate 422 is bolted onto the support frame 421. The bearing plate 422 is in direct contact with the fixture and undertakes the functions of supporting and transitioning the fixture. When the bearing plate 422 is worn due to long-term use or needs to be adapted to different sizes of fixtures, the bearing plate 422 can be replaced by removing the bolts without replacing the entire support plate.

[0040] The guide frame 53 consists of a frame 1 and a first partition 531, and the storage frame consists of a frame 1 and a second partition 44. Both the first partition 531 and the frame 1, and the second partition 44 and the frame 1, form enclosed rectangular storage areas. These areas limit the jig's movement in the left-right and front-back directions, preventing it from shifting or tilting during storage or transfer. This ensures the jig remains in the precise position for feeding or storing, improving subsequent separation and transfer accuracy. The enclosed rectangular storage area can accommodate multiple jigs stacked together, and the partitions prevent the stacked jigs from shifting. The tilting mechanism ensures the stability of batch storage and facilitates initial manual batch loading. The partitions can be flexibly adjusted in installation position according to the fixture size (e.g., by adjusting the partition spacing with bolts). It can adapt to different specifications of silver film fixtures without replacing the entire frame, improving the equipment's versatility. The frame 1 is directly used as the supporting side of the frame, and only the partitions need to be added to form a storage frame. Compared with independently processing the complete frame, it reduces material usage and processing steps, thus lowering production costs. At the same time, the connection structure between the frame 1 and the partitions is simple, facilitating installation and maintenance.
