[0038] The following will describe the implementation of the present invention in detail with reference to the accompanying drawings in the embodiment diagram of the present invention.

[0039] The transmission device for the glove box transition compartment provided in this embodiment includes two or more stacked transmission plates; a sliding assembly is provided between the transmission plates, and a motor and a rack corresponding to the motor are also provided; the upper transmission plate is driven by the motor and cooperates with the rack to make the upper transmission plate slide along the length direction of the lower transmission plate based on the sliding assembly; on the top transmission plate, a material pushing assembly is provided, and the material is pushed along the length direction of the transmission plate through the material pushing assembly.

[0040] The sliding assembly includes a rail and a slider that cooperates with the rail. A rack is provided on the lower surface of the upper transmission plate, and a motor is provided on the upper surface of the lower transmission plate. The rail is fixed to the upper surface of the lower transmission plate, and the slider is mounted on the rail. The lower surface of the upper transmission plate is fixed to the slider, and the gear on the motor engages with the rack. Furthermore, two sets of sliding assemblies are provided between the transmission plates. The two sets of sliding assemblies are symmetrically arranged on either side of the transmission plates, and the direction of the slide rails is parallel to the length of the transmission plates.

[0041] The material push assembly includes a cylinder, a magnetic switch and a cylinder slider mounted on the cylinder, and a paddle mounted on the slider. The paddle is fixed to the slider at one end and free at the other, extending perpendicularly and upwardly from the topmost conveyor plate. Driven by the cylinder, the paddle moves along the length of the topmost conveyor plate. Furthermore, there are two sets of material push assemblies, both mounted on the topmost conveyor plate; these two sets push the material in opposite directions.

[0042] In one embodiment, a photoelectric sensing assembly is positioned between the transmission plates to detect the movement of the transmission plates. The photoelectric sensing assembly includes a sensing plate and a photoelectric switch, each secured to opposing surfaces of two adjacent transmission plates. Two photoelectric switches are provided, spaced a certain distance apart and arranged along the length of the transmission plates in the path of the sensing plate.

[0043] In one of the embodiments, a drag chain is further provided on the bottom transmission plate, and the bending direction of the drag chain is consistent with the length direction of the bottom transmission plate; a drag chain mounting block is provided on the upper transmission plate adjacent to the bottom transmission plate, and the upper end of the drag chain is fixed on the drag chain mounting block.

[0044] In one embodiment, a material limiting assembly and a material detection device are also provided on the top-level transmission plate; the material limiting assembly is arranged at intervals along the circumferential direction of the top-level transmission plate to form a material movement area; the material detection device is arranged on the side where the material enters to detect whether there is material.

[0045] It's worth noting that if the transmission device is placed upright on a flat surface, the stacked transmission plates are described from bottom to top. Therefore, the upper, lower, and topmost transmission plates mentioned in this embodiment are relative positional descriptions. That is, relative to the transmission plates on the lower layer, the upper transmission plate is adjacent to and located above it; and relative to the transmission plates on the upper layer, the lower transmission plate is adjacent to and located below it. Furthermore, the number of stacked transmission plates is determined based on demand. If there are two layers of stacked transmission plates, the topmost transmission plate is equivalent to the upper transmission plate, and the bottommost transmission plate is equivalent to the lower transmission plate.

[0046] See Figures 1 to 6 , which is a schematic structural diagram of a transmission device of a glove box transition compartment provided in this embodiment. The transmission plate is arranged in three layers, namely, from bottom to top, the first transmission plate 1, the second transmission plate 13 and the third transmission plate 28.

[0047] The first transfer plate 1 is connected to the transition chamber via screws. Sliding assemblies are symmetrically arranged on both sides of the top surface of the first transfer plate 1. These assemblies include first rails 2 and first sliders 21 that mate with the first rails 2. The orientation of the first rails 2 aligns with the length of the first transfer plate 1. The first rails 2 are screwed onto the top surface of first rail mounting blocks 3, which are secured to the top surface of the first transfer plate 1 via screws. First rail stoppers 4 are also provided at each end of the first rails 2 and are secured to the first transfer plate 1 via screws. A drag chain 5 is also provided on the first transmission plate 1. The lower end of the drag chain 5 is mounted on the first transmission plate 1 by screws, and the upper end of the drag chain 5 is fixed to the drag chain mounting block 6 by screws. The drag chain mounting block 6 is mounted on the lower surface of the second transmission plate 13 by screws, and the bending direction of the drag chain 5 is consistent with the length direction of the bottom plate; the first servo motor 7 is located next to the drag chain 5, and the first servo motor mounting seat 8 is mounted on the end face close to the shaft by screws. The lower surface of the first servo motor mounting seat 8 is in close contact with the upper surface of the first transmission plate 1 and is fixed to the first transmission plate 1 by screws. The orientation of the motor 7 is aligned with the width of the first transmission plate 1. A first gear 9 is keyed to the shaft of the first servo motor 7 and secured with stops at both ends. A first rack 10 meshes with the first gear 9 and is screwed to the lower surface of the second transmission plate 13. The orientation of the first rack 10 aligns with the length of the second transmission plate 13. Two first photoelectric switches 11 are also located on the sides of the upper rail of the first transmission plate 1. These switches are spaced a certain distance apart, along the length of the first transmission plate 1, in the path of the sensor plate. A first sensor plate 12 is screwed to the center of the side of the second transmission plate 13. As the second transmission plate 13 moves, the first sensor plate 12 moves between the detection slots of the two first photoelectric switches 11. It is worth noting that the positions of the first photoelectric switches 11 and the first sensor plate 12 can be interchanged, as long as they can detect and sense whether the second transmission plate 13 has reached a specific position or state during movement. This is not limited to the positional relationship described in this embodiment.

[0048] The lower surface of the second transmission plate 13 is fixed to first sliders 21 on either side, and the first sliders 21 and the second transmission plate 13 are connected by screws. Sliding assemblies are symmetrically arranged on both sides of the upper surface of the second transmission plate 13. These sliding assemblies include second rails 14 and second sliders 141 that cooperate with the second rails 14. The orientation of the second rails 14 aligns with the length of the second transmission plate 13. The second rails 14 are screwed to the upper surface of the second rail mounting blocks 15, which are screwed to the upper surface of the second transmission plate 13. Second rail stoppers 16 are also provided at each end of the second rails 14, and are secured to the second transmission plate 13 by screws. A long rectangular through-hole is provided along the length of the second rail 14, deviating to the left side of the second transmission plate 13. The length of this through-hole matches the maximum motion path of the second servo motor 17.

[0049] A second servo motor 17 is mounted vertically on the lower surface of the second transmission plate 13. The end surface of the second servo motor 17, located closest to the shaft, passes through a through-hole in the second transmission plate 13 and is screwed to a second servo motor mounting bracket 18. The second servo motor mounting bracket 18 is screwed to the upper surface of the second transmission plate 13. A second gear 19 is fixed to the shaft of the second servo motor 17 using a flat key. A second rack 20 meshes with the second gear 19 and is screwed to the lower surface of a third transmission plate 28. The orientation of the second rack 20 aligns with the length of the third transmission plate 28. Two second photoelectric switches 21 are also located in the center of the upper surface of the second transmission plate 13. These two second photoelectric switches 21 are spaced a certain distance apart and arranged along the length of the second transmission plate 13, along the path of the sensor plate's movement. A second sensor plate 22 is screwed to the center of the lower surface of the third transmission plate 28. As the third transmission plate 28 moves, the second sensor plate 22 moves between the detection slots of the two second photoelectric switches 21. It is worth noting that the positions of the second photoelectric switch 21 and the second sensor plate 22 can be interchanged, as long as they can detect and sense whether the third transmission plate 28 has reached a specific position or state during movement, and are not limited to the position relationship described in this embodiment.

[0050] The lower surface of the third transfer plate 28 is fixed to the second sliders 141 on either side, connected to the third transfer plate 28 by screws. A material push assembly is located on the lower surface of the third transfer plate 28, near the second rack 20. This assembly includes a cylinder, a magnetic switch 26 and a cylinder slider 261 mounted on the cylinder, and a paddle 27 mounted on the slider. Two sets of material push assemblies are mounted on the third transfer plate 28. These two sets of material push assemblies push material in opposite directions, one for pushing material out of the glove box and the other for pushing material into the glove box. Two long rectangular through-holes are provided in the center of the third transfer plate 28, their lengths matching the maximum travel path of the cylinder in the material push assembly.

[0051] The cylinders in the two material propulsion assemblies are designated as the feed cylinder 23 and the discharge cylinder 24, respectively. These cylinders are preferably rodless cylinders. Each cylinder is equipped with two sets of magnetic switches 26, which detect the piston position. These cylinders are arranged along the length of a third conveyor plate 28. Cylinder mounting blocks 25 are screwed onto the lower surface of the third conveyor plate 28. These blocks secure the ends of the cylinders 23 and 24 to the lower surface of the third conveyor plate 28. Cylinder sliders 261 are respectively provided on the feed cylinder 23 and the discharge cylinder 24, and a paddle 27 is provided on the cylinder slider 261. One end of the paddle 27 is fixed on the cylinder slider 261, and the other end is a free end. The free end is perpendicular to the third transmission plate 28 and extends upward through the through hole on the third transmission plate 28 for a part of its length, so that it can push the material located on the upper surface of the third transmission plate 28 to move with the movement of the cylinder slider 261; it is worth noting that the two paddles 27 push the material in opposite directions.

[0052] The third transmission plate 28 is also provided with a material limiting assembly and a material detection device 29. The material limiting assembly includes a number of material limiting blocks 31, which are arranged at intervals along the upper surface of the third transmission plate 28 in a circumferential direction to form a material movement area. In this embodiment, the material movement area is rectangular, and the material moves within this rectangular area to prevent it from falling. There are two sets of material detection devices 29, which are arranged near the periphery of the material movement area and located on the side where the material enters. In this embodiment, the two sets of material detection devices 29 are located on the left periphery of the material movement area and are arranged at both ends of the left side. The material detection device 29 is mounted on the material detection device mounting block 30 by screws, and the material detection device mounting block 30 is also mounted on the upper surface of the third transmission plate 28 by screws. The material detection device 29 can be a photoelectric switch, a proximity switch, a laser sensor, etc., preferably a photoelectric switch.

[0053] It is worth noting that when the transmission plate is set to three or more layers, its structure is similar to the three-layer transmission plate structure provided in this embodiment. The structure of the added intermediate layer transmission plate can be set with reference to the structure of the second transmission plate 13, which will not be elaborated here.

[0054] When materials need to be transferred into the glove box, the transition chamber is filled with air and the outer door is opened. The first servo motor 7 receives the control signal and runs, driving the second transfer plate 13 and the third transfer plate 28 to move to the designated position outside the glove box along the first slide rail 2 and the second slide rail 14 respectively, and the first sensor plate 12 moves with the second transfer plate 13. The function of the first photoelectric switch 11 is to detect the position of the first sensor plate 12 to ensure that the moving stroke of the second transfer plate 13 and the third transfer plate 28 are between the two first photoelectric switches 11 to avoid collision. At the same time, the second The servo motor 17 receives the control signal and runs, driving the third transmission plate 28 to move along the second slide rail 14 to the specified position outside the glove box, and the function of the second photoelectric switch 21 is the same as that of the first photoelectric switch 11. Then, the material is placed by hand or by a robotic arm into the material movement area surrounded by the material limit block 31 on the third transmission plate 28. Then, the material detection device 29 detects the position of the material and transmits the signal to the host computer; then the host computer controls the operation of the feeding cylinder 23, and the cylinder slider 261 on the feeding cylinder 23 drives the paddle 27 to push the material to move. The magnetic switch 26 at the end of the feeding cylinder 23 detects the position of the cylinder slider 261 and transmits the signal to the host computer. The host computer then controls the feeding cylinder 23 to operate, and the cylinder slider 261 drives the paddle 27 to return to its original position. The magnetic switch 26 set at the original position detects the position of the cylinder slider 261 and transmits the signal to the host computer. The host computer then controls the first servo motor 7 and the second servo motor 17 to operate, driving the second transmission plate 13 and the third transmission plate 28 along the first slide rail 2 and the second slide rail 14. , moves to its original position inside the glove box, at which time the first slider 21 and the second slider 141 are respectively in the middle position of the first slide rail 2 and the second slide rail 14; then the transition cabin closes its door and is filled with the same gas as that in the glove box. When the pressure is appropriate, the inner door is opened, and then the host computer controls the first servo motor 7 and the second servo motor 17 to operate, driving the second transmission plate 13 and the third transmission plate 28 to move along the first slide rail 2 and the second slide rail 14 into the designated position inside the glove box, and then the human hand or the robotic arm in the glove box takes the material, completing the material transmission.

[0055] The transmission device for the glove box transition compartment provided by the present invention utilizes a motor-driven gear mechanism to transmit materials. The motor enables high-precision position control and high positioning accuracy, meeting the high positioning accuracy requirements of a robotic arm. The motor exhibits high reliability during repeated transmission. Maintenance is relatively simple, requiring only regular checks of the motor and controller status. Furthermore, a material propulsion assembly is provided on the third transmission plate 28 to propel material between the leading and trailing ends of the third transmission plate 28 along its length, thereby increasing the length of the material exiting the bin to 1.5 times the length of the transmission device. Two sets of material detection devices 29 are also provided on the third transmission plate 28 to detect the placement of the material. A material limit assembly is also provided to limit the movement of the material on the third transmission plate 28, thereby determining the material's position and facilitating the robotic arm's grasping of the material.

[0056] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
