Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to an optical disc transmission mechanism and device. Background Technology

[0002] Space is limited in fully automatic optical disc burning and printing equipment. As the structure of these devices becomes increasingly compact, and data security requirements become more stringent, effectively utilizing space to output optical discs to the outside of the device without opening the door and enabling rapid switching of output modes has become a crucial task in the overall structural design.

[0003] Based on a space-constrained device structure, this design aims to meet users' needs for optical disc output while allowing them to quickly switch between output modes. Currently, the conventional optical disc output method involves a robotic arm grasping the disc to be output, moving it above the output disc track, and releasing the disc. The disc then slides out along the track under its own weight into the output drum below the device's output port. This method requires a sufficient tilt angle for the disc to slide out smoothly, a smooth and flat track surface, and a significant amount of vertical space. Therefore, the conventional optical disc output method cannot meet the needs of compact devices. Summary of the Invention

[0041] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0042] Example 1

[0043] This utility model embodiment provides an optical disc transmission mechanism, such as... Figures 1-8As shown, the optical disc transport mechanism includes a drive component (e.g., a motor 22, a synchronous pulley 23, a synchronous belt 24, and a smooth idler wheel 25), a guide rail 32, and a transport tray 1;

[0044] The transfer tray is set on the guide rail 32, and the drive component is connected to the transfer tray 1 to drive the transfer tray 1 to slide back and forth along the guide rail 32 between a preset first transfer position and a second transfer position to transfer optical discs.

[0045] The conveying pallet 1 has a tray opening and an opening and closing structure (e.g., formed by the first end of the pallet block 15 and one side edge of the pallet opening and closing plate 14); the position of the opening and closing structure corresponds to the position of the tray opening; the opening and closing structure includes a preset closed state and an open state.

[0046] In the closed state, the opening and closing structure is used to support the target object; the target object is an optical disc or a detachable tray 12; the tray 12 can be used to support the optical disc; in the open state, the opening and closing structure forms the optical disc dropping area.

[0047] The optical disc transport mechanism provided in this embodiment of the present invention has a transport tray mounted on a guide rail 32. A driving component is connected to the transport tray 1, thereby driving the transport tray 1 to slide back and forth along the guide rail 32 between a preset first transport position and a second transport position to transport optical discs. The first and second transport positions are set according to actual conditions and are not specifically limited here. The transport tray has a drop opening and an opening / closing structure; the position of the opening / closing structure corresponds to the drop opening position, thus enabling switching of transport modes. In the first transport mode, during the transport process, the opening / closing structure remains closed while moving between the first and second transport positions. The opening / closing structure carries a detachable tray, which carries the optical disc. Upon reaching the second transport position, the carried optical disc can be removed. In the second transport mode, the opening / closing structure is closed at the first transport position, directly carrying the optical disc. Upon reaching the second transport position, the opening / closing structure is triggered to open, and the optical disc falls from the opening / closing structure. The optical disc transport mechanism provided in this embodiment of the present invention has a compact structure, occupies little height space, effectively meets the needs of compact devices, and allows for simple and quick switching of transport modes.

[0048] In some embodiments, the transfer tray 1 further includes a tray plate 11, a tray opening and closing plate 14, and a carrier component (e.g., which may be composed of a tray block 15);

[0049] The pallet plate 11 is provided with a tray drop opening; the pallet opening and closing plate 14 and the tray carrier component are provided on the first side of the pallet plate 11, and the first end of the tray carrier component and one side edge of the pallet opening and closing plate 14 form an opening and closing structure.

[0050] In the closed state, the first end of the tray component and the edge of the tray opening and closing plate 14 are used to carry the target object;

[0051] In the open state, the space formed by the first end of the carrier component and the edge of the tray opening plate 14 constitutes the optical disc dropping area.

[0052] Optionally, the pallet opening and closing plate 14 can move back and forth relative to the pallet plate along the guide rail direction; the pallet opening and closing plate 14 is connected to the pallet component via a linkage component (e.g., a stepped screw 19);

[0053] When the pallet opening and closing plate 14 is in the preset initial position of the pallet, the first end of the pallet component and the pallet opening and closing plate 14 are in the closed state; the first end of the pallet component and the edge of the pallet opening and closing plate 14 protrude inward toward the pallet opening.

[0054] When the pallet opening and closing plate is in the preset target position of the pallet plate, the pallet opening and closing plate can be used to rotate the pallet component through relative movement and linkage components, so that the first end of the pallet component and the pallet opening and closing plate 14 are in the open state, and the first end of the pallet component and the edge of the pallet opening and closing plate 14 are retracted to the outside of the pallet opening edge.

[0055] In some embodiments, the optical disc transport mechanism has a first transport mode and a second transport mode; a disc baffle component (e.g., composed of 4 disc baffle posts 13) is provided around the disc drop opening on the second side of the tray.

[0056] In the first delivery mode, the opening and closing structure is always in the closed state, and the first end of the tray component and the edge of the tray opening and closing plate 14 are used to support the tray 12; the first end of the tray component, the edge of the tray opening and closing plate 14, the tray 12, the drop plate opening and the tray retainer component constitute the space for accommodating the optical disc.

[0057] For example, the tray 12 is clamped onto the tray block 15 and the tray opening and closing plate 14. The four baffle posts 13 and the tray 12 form a space for holding an optical disc. The optical disc is picked up by the robotic arm inside the equipment and placed into the space. The conveyor tray is fastened to the guide rail slider. One side of the conveyor tray 1 is fastened by the timing belt 24. The rotation of the motor shaft 22 drives the timing pulley 23 fastened to the motor shaft to rotate. The timing pulley 23 drives the timing belt 24 to rotate. The rotation of the timing belt 24 drives the conveyor tray 1 to slide back and forth along the guide rail as a guide. The conveyor tray is output to the outside of the equipment through the equipment output port.

[0058] In the second delivery mode, when the tray opening and closing plate is in the initial position, the first end of the tray component and the edge of the tray opening and closing plate are used to carry the optical disc; the first end of the tray component, the edge of the tray opening and closing plate, the disc drop opening and the disc retainer constitute a space for accommodating the optical disc; when the tray opening and closing plate is in the target position, the first end of the tray component and the tray opening and closing plate are in the open state.

[0059] In some embodiments, the linkage component includes a rotating shaft (e.g., formed by a stepped screw 19); the tray opening and closing plate 14 is connected to the second end of the tray component; the rotating shaft passes through the tray component and is fixed to the second side of the tray plate 11;

[0060] The second side of the pallet plate 11 is also provided with one or more limiting guide components (for example, it can be composed of 6 stepped screws 16); the pallet opening and closing plate is connected to the conveyor pallet by one or more tension springs 18, and the pallet opening and closing plate is provided with one or more guide grooves, and a limiting guide component is provided in each guide groove.

[0061] Each guide groove is used to guide the movement direction of the corresponding limiting guide component and restrict the movement position of the corresponding limiting guide component, so that the pallet opening and closing plate moves back and forth between the initial position and the target position relative to the pallet plate.

[0062] Each tension spring is used to provide tension to the corresponding limiting guide member at the first end of the guide groove to bring the pallet opening plate to the initial position, or to provide tension to the limiting guide member at the second end of the guide groove to move the pallet opening plate from the target position to the initial position.

[0063] In some embodiments, the optical disc transport mechanism further includes a first movable limiting component (e.g., a limiting post 4), which is used to be mounted on the device on which the optical disc transport mechanism is installed; the tray opening and closing plate is also provided with a second movable limiting component (e.g., a portion on the tray opening and closing plate that fixes a tension spring) that cooperates with the first limiting component.

[0064] The first and second movement limiting components are used to move the pallet opening and closing plate relative to the pallet plate.

[0065] For example, when switching the transmission mode, the tray 12 on the transmission tray 1 is removed, the optical disc is carried by the tray block, the upper limit stop is fastened to the output port side of the device, the transmission tray slides out to the front end of the output port, the tray opening and closing plate is blocked by the second movement limit component by the limit stop, the tray opening and closing plate pulls the tray block 15 to rotate, the tray block 15 rotates open, and the optical disc falls into the optical disc drum fastened below the output port of the device.

[0066] The optical disc transmission mechanism provided in the various embodiments of this utility model has a compact structure and supports rapid switching of output modes.

[0067] Based on the above embodiments, specific embodiments are provided below.

[0068] like Figure 1As shown, a specific embodiment of an optical disc transport mechanism includes a guide rail mounting bracket 31 fixedly installed on the device, a guide rail 32 fastened to the guide rail mounting bracket, a transport tray 1 fastened to the guide rail slider, a motor mounting bracket 21 fixedly installed on the device, a stepper motor 22 and a smooth idler wheel 25 fastened to the motor mounting bracket, a synchronous pulley 23 fastened to the rotating shaft of the stepper motor 22, the synchronous pulley 23 driving a synchronous belt 24, and the synchronous belt 24 being fastened to one side of the transport tray 1 by a synchronous belt clamping block 26.

[0069] like Figures 2-5 As shown, four baffle posts 13 are fastened to the transfer tray plate 11. The four baffle posts 13, two tray blocks 15, and tray opening and closing plate 14 are fastened by two stepped screws 19. The two stepped screws 19 serve as the rotation axis of the two tray blocks 15, and six stepped screws 16 serve as guide limit pins for the tray opening and closing plate 14. Two spring supports 17 are fastened below the transfer tray plate 11, and two tension springs 18 are fastened to the two spring supports 17 and the tray opening and closing plate 14. Through the tension of the two tension springs 18, the tray opening and closing plate 14 and the two tray blocks 15 are kept in the closed state, and the tray plate 12 is clamped above the tray blocks 15 and the tray opening and closing plate 14. The tray plate 12, the four baffle posts 13, and the transfer tray plate 11 form a space for receiving optical discs.

[0070] In the specific implementation process, the robotic arm inside the device grabs the optical disc and places it into the optical disc receiving space 7 of the transfer tray 1. The rotation of the motor shaft of the stepper motor 22 drives the synchronous pulley 23, which is fastened to the motor shaft, to rotate. The rotation of the synchronous pulley 23 drives the synchronous belt 24 to rotate. The synchronous belt 24 is fastened to the transfer tray 1. The rotation of the synchronous belt 24 drives the transfer tray 1 to slide out of the device output port and stop at a set position outside the device output port, guided by the guide rail 32. After the user takes away the optical disc and operates the device, the motor shaft of the stepper motor 22 rotates in the opposite direction, which drives the synchronous belt 24 to rotate through the synchronous pulley 23. The synchronous belt 24 drives the transfer tray 1 to slide into the device and stop at the initial position, guided by the guide rail 32.

[0071] like Figure 6 and 7 As shown, switch the transmission mode, remove the tray 12, tighten two limit stops 4 on the output port side of the device, tighten the optical disc drum device 5 below the output port, tighten the drum device 5 below the output port with two screws 6, and tighten the drum 52 on the drum bracket 51 with four screws 53.

[0072] Four baffle posts 13, tray plate 11, tray opening and closing plate 14 and two tray blocks 15 form a space 8 for holding an optical disc.

[0073] In the specific implementation process, the robotic arm inside the equipment grabs the optical disc and places it into the optical disc receiving space 8 of the conveyor tray 1. The rotation of the motor shaft of the stepper motor 22 drives the synchronous pulley 23, which is fastened to the motor shaft, to rotate. The rotation of the synchronous pulley 23 drives the rotation of the synchronous belt 24, which is fastened to the conveyor tray 1. The rotation of the synchronous belt 24 causes the conveyor tray 1 to slide out of the equipment output port along the guide rail 32. Two limit posts 4 fastened to the side of the equipment output port prevent the tray opening and closing plate 14 from moving further outward. The conveyor tray 11 continues to move forward under the drive of the synchronous belt 24. The tray opening and closing plate 14 moves relative to the conveyor... The pallet 11 moves backward, and the six stepped screws 16 fastened to the conveyor pallet 11 serve as guides and limits. The pallet opening and closing plate 14 drives the two pallet blocks 15 to rotate. The two stepped screws 19 fastened to the conveyor pallet 11 serve as the rotation axis of the pallet blocks 15. When the conveyor pallet 1 stops at the position set outside the equipment output port, the pallet opening and closing plate 14 completely leaves the drop port of the conveyor pallet 11, and the two pallet blocks 15 rotate completely away from the drop port of the conveyor pallet 11. The optical disc falls from the drop port of the conveyor pallet 11 into the tray 52 below the equipment output port. The tray 52 is fastened to the tray bracket 51.

[0074] The reverse rotation of the motor shaft of the stepper motor 22 causes the conveyor pallet 11 to slide into the equipment under the guidance of the guide rail 32, driven by the synchronous belt 24. The pallet opening and closing plate 14 moves away from the two limiting posts 4 fastened to the output side of the equipment. Under the pull of the two tension springs 18 fastened to the pallet opening and closing plate 14 and the two spring pillars 17 fastened to the conveyor pallet 11, the pallet opening and closing plate 14 moves forward relative to the conveyor pallet 11. Guided and limited by the four stepped screws 16 and two stepped screws 19 fastened to the conveyor pallet 11, the pallet opening and closing plate 14 returns to its initial position relative to the conveyor pallet 11. The pallet opening and closing plate 14 drives the two pallet blocks 15 to rotate in the opposite direction. With the two stepped screws 19 fastened to the conveyor pallet 11 as the rotation axis, the two pallet blocks 15 rotate back to their initial position relative to the conveyor pallet 11. The conveyor pallet 1 returns to its initial position under the control of the stepper motor 22.

[0075] This specific embodiment of the optical disc transport mechanism includes a guide rail bracket and a guide rail fastened to the device. The guide rail serves as a guide for the optical disc output mechanism. A transport tray is fastened to the guide rail slider. A motor, a motor bracket, and a timing belt are fastened to one side of the transport tray. The timing belt is fastened to one side of the transport tray and drives the transport tray to slide in and out back and forth under the guidance of the guide rail. It supports quick switching of transport modes. The tray is removed from the transport tray, and two limiting posts are fastened to the device output port side. An output disc drum is fastened below the device output port. When the optical disc output mechanism outputs to the outside of the device port, the two limiting posts block the tray opening and closing plate below the transport tray. The transport tray continues to move outward, and the tray opening and closing plate drives the tray block to rotate. The tray opening and closing plate and the tray block leave the transport tray and fall into the disc drum below the output port.
