  • the fixing member can be two spaced-apart step pins, which cooperate with the two pin holes at the bottom of the tray to fix the tray in the cache rack 460, thereby positioning the tray and preventing the tray from shaking or falling.
  • multiple storage positions can be set on the storage board 462, such as 4, 6, 8, 10 or other values.
  • the fixing member is an elastic contact member
  • the position is a positioning groove
  • the elastic contact member is disposed in the positioning groove
  • the elastic contact member is when the container is placed in the positioning groove. It can contact the container and produce elastic deformation to position the container and prevent the container from shaking or falling.
  • Different experimental supplies can be placed on different storage boards 462 in the buffer rack 460, for example, one layer is used to place containers, and the other layer is used to place trays.
  • the buffer rack 460 when the buffer rack 460 is disposed on the side wall of the sealed chamber, the buffer rack 460 directly disposes the storage plate 462 on the side wall, thereby further saving space.
  • the distance between the lowest storage board 462 in the buffer rack 460 (that is, the storage board closest to the bottom wall) and the bottom wall is greater than the height of the functional unit 400 placed between the buffer rack 460 and the robot arm 300, so that the robot arm 300 can be avoided When taking and placing experimental supplies from the storage plate 462, the functional unit 400 interferes with the storage plate 462.
  • the glove box system 1000 also includes a transfer rack 420.
  • the transfer rack 420 is disposed on the bottom wall of the sealed chamber.
  • the robot arm 300 drives the pallet transfer clamp 530 to place the pallet on the transfer rack 420.
  • the robot arm 300 drives the transfer rack 420.
  • the container transfer gripper moves the containers in the pallet to the functional unit 400 .
  • the transfer rack 420 is specifically used for container transfer. For example, when the experimental supplies obtained by the exchange warehouse 210 are trays containing multiple test tubes, when the test tubes in the tray are to be tested, the entire tray cannot be sent to the functional unit 400 for experiments. At this time, the tray can be placed on the transfer rack 420, and the test tubes can be taken out one by one.
  • the transfer rack 420 includes a plurality of transfer racks 420 with different heights. The higher the transfer rack 420, the farther away from the robotic arm 300 is. This can prevent the high transfer rack 420 from interfering with the low transfer rack 420.
  • the transfer rack 420 may be disposed close to the switching device 200 .
  • the plurality of transfer racks 420 include a first transfer rack 470 , a single pallet rack 480 and a second transfer rack 490 .
  • the height of the first transfer rack 470 can be set to 120mm
  • the height of the second transfer rack 490 and the single pallet rack 480 can be set to 90mm
  • the first transfer rack 470 and the second transfer rack 490 can be used to place container pallets.
  • the single pallet rack 480 can be used to place tip trays or filter tip trays.
  • the transfer rack 420 includes a placement plate.
  • the placement plate is provided with step pins, and the step pins are used to be plugged into pin holes provided at the bottom of the pallet. And/or, both ends of the placement plate are provided with tray clamping parts to clamp the tray.
  • the step pins or clamping parts position the pallet to prevent the pallet from shaking or being picked up by the robotic arm 300 .
  • the placement plates of the first transfer rack 470 and the second transfer rack 490 are provided with step pins
  • the placement plates of the single pallet rack 480 are provided with step pins and clamping parts.

Abstract

La présente demande divulgue un système de boîte à gants, comprenant un corps de boîte, un dispositif d'échange, un bras mécanique, une unité fonctionnelle et une pièce. Le corps de boîte est pourvu d'une chambre scellée, et le dispositif d'échange est monté dans le corps de boîte pour transférer un article expérimental entre l'extérieur et la chambre scellée. Le bras mécanique, l'unité fonctionnelle et la pièce sont tous situés dans la chambre scellée. La pièce est reliée au bras mécanique, et le bras mécanique entraîne la pièce à se déplacer, de sorte que la pièce entraîne l'article expérimental à se déplacer du dispositif d'échange à l'unité fonctionnelle, et entraîne l'article expérimental à se déplacer de l'unité fonctionnelle au dispositif d'échange. L'unité fonctionnelle est utilisée pour stocker l'article expérimental et/ou pour effectuer une tâche expérimentale à l'aide de l'article expérimental. Un processus d'expérience présente un degré élevé d'automatisation, ne nécessite pas de participation à un grand nombre d'expérimentateurs, comprend un cycle de préparation d'échantillon court, et présente un taux de réussite d'expérience élevé.
