As shown in fig. 1, in the present embodiment, the buffer conveying apparatus includes at least one housing box 20, and the housing box 20 can be used as a container for carrying the carriers 40 to house one or more carriers 40. Fig. 6 is a schematic perspective view of a housing box 20 according to an embodiment of the present utility model, and fig. 7 is a schematic front view of a housing box 20 according to an embodiment of the present utility model. Referring to fig. 6 and 7, the receiving box 20 includes at least one receiving groove 21, the receiving groove 21 includes an opening through which the carrier 40 passes, and the receiving groove 21 is shaped to match the carrier 40 so that the carrier 40 can be positioned and received in the receiving groove 21. In an alternative embodiment, the housing box 20 includes a plurality of receiving slots 21 for receiving a plurality of carriers 40, so that space can be fully utilized to realize the buffering of the carriers 40 and the workpieces carried by the carriers 40. The plurality of receiving grooves 21 of the receiving box 20 may be spaced apart to separate the plurality of carriers 40, so as to facilitate the removal and placement of the carriers 40. A partition may be provided between adjacent accommodating grooves 21 to completely partition the different accommodating grooves 21; alternatively, the adjacent accommodating grooves 21 may have a hollow structure smaller than the carrier 40, so that the carrier 40 is prevented from falling from one accommodating groove 21 to the other accommodating groove 21, and the weight of the accommodating box 20 is reduced.

Referring to fig. 1 to 3, in the present embodiment, the buffer conveying apparatus includes two loading and unloading assemblies 30, each loading and unloading assembly 30 is disposed in one loading and unloading area B1 or B2 of the two loading and unloading areas B1, B2 corresponding to the loading and unloading assembly 30, that is, one of the two loading and unloading assemblies 30 is disposed in the loading and unloading area B1, and the other is disposed in the unloading and unloading area B2.

The structure of the two loading and unloading assemblies 30 may be substantially identical. Referring to fig. 8 and 9, each loading and unloading assembly 30 includes a loading and unloading device 31 and a carrying device 32, respectively, wherein the carrying device 32 is used for driving the accommodating box 20 to move between the buffer channel 10 and the loading and unloading area, and the carrying device 32 includes a carrying table 321 for carrying the accommodating box 20; the loading and unloading device 31 is disposed at one side of the carrying device 32, and is configured to load the carrier 40 into the accommodating groove 21 of the accommodating box 20 carried by the carrying table 321 or to take out the carrier 40 from the accommodating groove 21 of the accommodating box 20 carried by the carrying table 321. The loading and unloading device 31 includes a positioning table 311 for positioning the carrier 40, the positioning table 311 is disposed on a side of the loading and unloading device 31 near the carrying table 321, and the loading and unloading device 31 can drive the carrier 40 to move between the positioning table 311 and the carrying box 20 carried by the carrying table 321, so as to realize loading and unloading of the carrier 40 relative to the carrying box 20. By the cooperation of the loading and unloading device 31 and the carrying device 32, loading and unloading of the carrier 40 in the housing box 20 and transfer of the housing box 20 between the buffer area a and the loading and unloading areas B1 and B2 can be realized, and transfer of the carrier 40 between the buffer area a and the loading and unloading areas B1 and B2 can be realized.

Referring to fig. 9, when the carrying device 32 takes the storage cassette 20, the storage cassette 20 is placed on the stage 321 in a predetermined posture, so that the loading and unloading device 31 loads and unloads the carrier 40 to and from the storage cassette 20. When the housing cartridge 20 is placed on the carrying table 321, the plurality of housing grooves 21 of the housing cartridge 20 are arranged along the first axis direction, and the openings of the housing grooves 21 are disposed in the second axis direction of the housing cartridge 20, which intersects the first axis direction, for example, the included angle between the first axis direction and the second axis direction may be 80 °, 90 °, 100 °, or the like. For example, referring to fig. 7, the arrangement direction of the plurality of accommodating grooves 21 of the accommodating cassette 20 is substantially perpendicular to the opening direction of the accommodating groove 21. The first axis direction may be any direction in space, for example, may be a vertical axis direction (or an up-down direction), and the specific direction of the first axis direction is not limited in the embodiment of the present utility model.

In one embodiment, when the housing box 20 has a plurality of housing slots 21 and the plurality of housing slots 21 are aligned along the first axis direction (for example, the housing box 20 in fig. 6 and 7), the handling device 32 may include a first driving mechanism 322, where the first driving mechanism 322 is connected to the carrying table 321 and is used to drive the housing box 20 on the carrying table 321 to move along the first axis direction. When the position of the positioning table 311 is relatively fixed, the first driving mechanism 322 drives the carrying table 321, so that the accommodating grooves 21 aligned with the positioning table 311 in the accommodating box 20 can be switched between different accommodating grooves 21, and the plurality of carriers 40 can be respectively placed into different accommodating grooves 21 from the positioning table 311, so that the plurality of carriers 40 are stacked in the accommodating box 20, or the plurality of carriers 40 stacked in the accommodating grooves 21 at different positions in the accommodating box 20 can be sequentially moved out onto the positioning table 311. When the plurality of receiving grooves 21 of the receiving box 20 are arranged at equal intervals along the first axis direction, the first driving mechanism 322 can adopt a step driving mode, so that each receiving groove 21 of the receiving box 20 can be aligned with the positioning table 311 more accurately under the driving of the first driving mechanism 322. Optionally, the first driving mechanism 322 may include a screw sliding table, which is beneficial to smoothly driving the accommodating box 20, so as to avoid damage or displacement caused by large vibration of the workpiece on the carrier 40 in the accommodating box 20.

Referring to fig. 9 and 10, in one embodiment, the conveyance device 32 includes a mounting frame 323 and a first conveyance mechanism 324.

The first conveying mechanism 324 is configured to drive the accommodating box 20 to move relative to the carrying device 32, so that the accommodating box 20 moves out of the carrying device 32 or receives the accommodating box 20 and moves the accommodating box 20 to a predetermined position in the carrying device 32. The specific form of the first transfer mechanism 324 may be selected to be suitable for stably moving the housing cartridge 20 according to actual needs, and for example, the first transfer mechanism 324 may be a belt transfer mechanism, a robot, a cylinder assembly, or the like.

For example, referring to fig. 9 and 10, the lifting mechanism 326 may drive the carrying platform 321 to move upwards to separate the housing box 20 from the surface of the first conveying mechanism 324, and when the first conveying mechanism 324 is required to drive the housing box 20 out of the carrying device 32, the carrying platform 321 moves downwards and may move below the surface of the first conveying mechanism 324 contacting with the housing box 20, so that the first conveying mechanism 324 can smoothly drive the housing box 20, and the blocking of the housing box 20 by the carrying platform 321 is avoided.

The present embodiment does not limit the specific shape of the mounting frame 323, and the mounting frame 323 may be formed in any shape that can facilitate stable connection with other components of the carrying device 32 and can allow the housing box 20 to be smoothly moved out and in. Alternatively, the mounting frame 323 includes a top plate 3231 and a bottom plate 3232 spaced apart a predetermined distance and disposed opposite to each other. The lifting mechanism 326 is disposed on the bottom plate 3232, the carrier 321 is disposed near the bottom plate 3232 and opposite to the top plate 3231, and the lifting mechanism 326 drives the carrier 321 to move relative to the top plate 3231 to change the distance between the carrier 321 and the top plate 3231.

Alternatively, the positioning mechanism 325 positions the housing box 20 in a direction intersecting the first axis direction on the stage 321.

The positioning mechanism 325 may use clamping, pin hole positioning, or other possible positioning means to position the housing cartridge 20. In an alternative embodiment, the positioning mechanism 325 positions the housing cartridge 20 in such a manner that two opposite directions perpendicular to the first axis direction are clamped against each other. In one embodiment, the positioning mechanism 325 includes a positioning plate 3251, a platen 3252, and a platen drive mechanism 3253. The positioning plate 3251 is connected to an end of the top plate 3231 away from the buffer area a, the pressing plate 3252 is disposed at an end of the top plate 3231 near the buffer area a, the positioning plate 3251 and the pressing plate 3252 are disposed opposite to each other at intervals along two opposite directions perpendicular to the first axis direction, and an area for positioning the housing box 20 is defined between the positioning plate 3251 and the pressing plate 3252. The platen driving mechanism 3253 is connected to the platen 3252 for driving the platen 3252 to move relative to the positioning plate 3251 to approach and separate from the positioning plate 3251. When a part of the accommodating box 20 enters the area defined by the positioning plate 3251 and the pressing plate 3252, the pressing plate 3252 can be driven by the pressing plate driving mechanism 3253 to move towards the direction close to the positioning plate 3251, so that the accommodating box 20 is pressed on the surface of the positioning plate 3251, and the accommodating box 20 is positioned; when the housing cassette 20 needs to be released, the platen driving mechanism 3253 only needs to drive the platen 3252 to move in a direction away from the positioning plate 3251. In order to avoid the blocking of the positioning mechanism 325 by the removal and the movement of the cassette 20 into and out of the handling device 32, the lifting mechanism 326 may be used to move the cassette 20 to avoid the pressing plate 3252 and the positioning plate 3251 when the cassette 20 needs to be removed from the handling device 32. In contrast to fig. 11 and 12, the lift mechanism 326 drives the carrier 321 in the first axis direction between the first station and the second station. Referring to fig. 11, when the carrier 321 moves to the first station, the housing magazine 20 on the carrier 321 is away from the first conveying mechanism 324 and is partially located in the area defined by the positioning plate 3251 and the pressing plate 3252, at which time the housing magazine 20 can be positioned by the positioning mechanism 325; referring to fig. 12, when the carrier 321 moves to the second station, the receiving box 20 on the carrier 321 contacts the first conveying mechanism 324 and is far away from the area defined by the positioning plate 3251 and the pressing plate 3252, and the receiving box 20 can be moved out of or into the conveying mechanism by the driving of the first conveying mechanism 324.

The loading and unloading driving device 313 can also drive the second joint 316 to connect with the carrier 40 and move between the material inlet and outlet channel 314 and the positioning table 311, so as to drive the carrier 40 to move between the material inlet and outlet channel 314 and the positioning table 311 beyond the spacer 315. The spacer 315 can prevent the carrier 40 from being mixed between the material inlet and outlet channel 314 and the positioning table 311, and simultaneously allow the carrier 40 to be transmitted to the outside and the loading and unloading operations between the carrier 40 and the receiving box 20 to be performed simultaneously without mutual interference, which is beneficial to improving the working efficiency. Optionally, the spacer 315 has a avoidance notch 3151 communicating with the material inlet and outlet channel 314 and the positioning table 311, where the position of the avoidance notch 3151 is configured to avoid the first engaging member 312 when the loading and unloading driving device 313 drives the first engaging member 312 to move, so as to avoid the first engaging member 312 from colliding with the spacer 315.

The manner in which the handling drive 313 drives the first engagement member 312 and the second engagement member 316 may be by motor drive, hydraulic drive, belt drive or other possible means. The different actions of the loading and unloading driving device 313 can be driven by the same driving mechanism or driven by different driving mechanisms. In an alternative embodiment, the handling drive 313 includes a mounting block 3131, a second drive mechanism 3132, and a fourth drive mechanism 3134.
