Description

Technical Field

[0001] The invention relates to a double-color PCR plate automatic pad printing leak detection production line, belonging to the technical field of PCR plate production. Background Art

[0002] PCR plates are widely used in genetics, biochemistry, immunology, medicine and other fields. They are not only used in basic research such as gene separation, cloning and nucleic acid sequence analysis, but can also be used for disease diagnosis or anywhere there is DNA or RNA. They are disposable consumables in the laboratory.

[0003] Among them, the two-color 96-well PCR plate is one of the important products. The production process is generally one-time injection molding, pad printing, secondary injection molding, leak detection, etc. In the existing technology, there is a problem of insufficient production continuity. Generally, it is necessary to manually collect the workpieces obtained by the primary injection molding equipment, send them to the pad printing equipment for pad printing, and then manually transport them to the secondary injection molding equipment for secondary injection molding. Finally, they need to be leak-tested one by one through the leak detection equipment, and manually screened for good and defective products. The production efficiency is low and the equipment occupies a large space. Summary of the Invention

[0004] The present invention proposes an automatic pad printing leak detection production line for two-color PCR plates, which aims to overcome the above-mentioned shortcomings of the prior art and realize the automatic pad printing leak detection production of two-color PCR plates.

[0005] The technical solution of the present invention is as follows: the automatic pad printing leak detection production line for two-color PCR plates comprises a first injection molding machine, a lifting material receiving tray mechanism, a pad printing device, a material unloading belt, a transfer belt, a material loading belt line mechanism, a lifting material unloading mechanism, a finished product lifting and transverse material receiving mechanism, an NG material receiving box and a finished product unloading belt, which are arranged adjacent to each other in sequence. A discharging manipulator is provided between the first injection molding machine and the lifting material receiving tray mechanism, a rotary conveying and sucking mechanism is provided next to the lifting material receiving tray mechanism, a pad printing loading mechanism is provided next to the rotary conveying and sucking mechanism, and the pad printing loading mechanism is fed to the material unloading belt by the rotary conveying and sucking mechanism. The unloading material belt extends and passes through the pad printing equipment in the middle. A transverse lifting robot is provided between the pad printing loading mechanism and the unloading material belt. A clamping, flipping and transferring mechanism is provided between the loading belt line mechanism and the lifting and unloading mechanism. A second injection molding machine is provided next to the finished product lifting and transverse material receiving mechanism. A picking and unloading mechanism is provided above the lifting and unloading mechanism, the second injection molding machine and the finished product lifting and transverse material receiving mechanism as a whole. The middle of the finished product lifting and transverse material receiving mechanism passes through the arc detection mechanism. A transverse lifting and discharging mechanism is provided above the end of the finished product lifting and transverse material receiving mechanism, the NG material receiving box and the end of the finished product unloading material belt as a whole. After a single injection molding cycle in the first injection molding machine, the PCR plate is moved by the discharge robot to the lifting receiving tray mechanism. The lifting receiving tray mechanism descends, and the rotary transport suction mechanism deflects and moves it to the pad printing loading mechanism. From there, it is moved to the pad printing equipment for pad printing. It is then transported forward by the transverse lifting robot to the unloading conveyor, from which it moves to the transfer conveyor, and then to the loading belt line mechanism. It is then flipped over by the gripping and flipping transfer mechanism and moved to the lifting unloading mechanism. The unloading mechanism then moves it to the second injection molding machine for a second injection molding cycle. After completion, the unloading mechanism removes the plate and places it on the finished product lifting and transverse receiving mechanism. The finished product lifting and transverse receiving mechanism descends and moves, passing through an arc detection mechanism for leak detection during movement. It then continues forward. If a good product is found, it is delivered to the finished product unloading conveyor for discharge by the transverse lifting discharge mechanism. If a defective product is found, it is deposited into the NG receiving box by the transverse lifting discharge mechanism. This enables automated pad printing and leak detection production of two-color PCR plates.

Positioning support posts are provided on the top surface of the transverse transfer mounting bracket. The PCR plate taken from the second injection molding machine by the material taking and discharge mechanism is placed on the array positioning posts of the finished product discharge block. The lifting drive cylinder, assisted by the lifting guide posts, drives the finished product tray downward, which is then driven transversely by the finished product transverse transfer module. When the tray reaches below the arc detection mechanism, it stops for leak detection and is then delivered to the end, where it is delivered to the NG receiving box or finished product discharge belt by the transverse lifting and discharge mechanism.

[0057] During operation, the PCR plate taken from the second injection molding machine 13 by the material taking and discharging mechanism 14 is placed on the array positioning column 158 of the finished product discharge block 157, and the lifting drive cylinder 154 drives the finished product tray 156 to descend with the assistance of the lifting guide column 155, and then is driven to move horizontally by the finished product transverse module 151. When it moves to the bottom of the arc detection mechanism 16, it pauses for leak detection and is then sent to the end, and is sent to the NG material receiving box 17 or the finished product unloading belt 18 by the transverse lifting and discharging mechanism.
