Technical Field

[0001] This invention relates to the field of loading and unloading technology for processing equipment, and in particular to a buffer device and a drilling device. Background Technology

[0002] The existing automatic loading and unloading mechanisms of drilling machines and other processing equipment are some distance from the main body of the drilling machine. In practical applications, a transition mechanism needs to be added in this space to transport the workpieces from the automatic loading and unloading mechanism to the processing equipment. This results in the existing loading and unloading mechanism occupying a large production space and requiring a large area of ​​the workshop production base, which in turn leads to low space utilization in the workshop and is not conducive to maximizing production efficiency.

[0045] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following is for reference. Figures 1-10 A caching device 100 according to an embodiment of the first aspect of the present invention is described.

[0047] refer to Figure 2 and Figure 3 According to an embodiment of the present invention, the buffer device 100 can be used in a drilling device 1004. The drilling device 1004 may include a main unit 200 and a buffer device 100. The main unit 200 includes a bed 201 and a conveying assembly disposed on the bed 201. The buffer device 100 is used to convey and receive workpieces to and from the main unit 200. The buffer device 100 includes a mounting frame 1 and a material rack 2.

[0048] The material rack 2 is movably mounted on the mounting frame 1 along a first direction and a second direction. The material rack 2 can be used to store and transfer workpieces 300. The second direction is parallel to the direction in which the material rack 2 transfers workpieces 300. For example, the first direction is up and down, and the second direction can be left and right. The material rack 2 has a first position and a second position. In the first position, the material rack 2 is adapted to dock with the conveying assembly of the host machine 200 to transfer the workpieces 300 on the material rack 2 to the host machine 200 for processing. In the second position, the material rack 2 is adapted to dock with the self-moving feeding device 1002 to transfer the workpieces 300 on the self-moving feeding device 1002 to the material rack 2. That is, the self-moving feeding device 1002 can replenish the material rack 2 with workpieces 300. Optionally, at this time, the material rack 2 can stop transferring workpieces 300 to the host machine 200.

[0049] For example Figure 2As shown, the main machine 200 has a bed 201, on which a base 203 for placing workpieces 300 can be provided. The conveying assembly can be flush with the base 203 to transfer the workpieces 300 on the material rack 2 to the base 203 for processing. The mounting frame 1 can be provided on one side of the bed 201 in the left-right direction, and the mounting frame 1 is arranged adjacent to the bed 201. The material rack 2 is movably mounted on the mounting frame 1 along a first direction and a second direction, wherein the first direction is the up-down direction and the second direction is the left-right direction. The material rack 2 has a first position and a second position on the mounting frame 1. When it is necessary to transfer the workpiece 300 to the host 200, the material rack 2 is controlled to move to the first position to dock with the transfer component of the host 200 to transfer the workpiece 300. After the workpiece 300 is transferred, the material rack 2 can be controlled to return to the second position to receive the workpiece 300 replenished by the mobile feeding device 1002. This cycle is repeated. The material rack 2 can temporarily store the workpiece 300 transported by the mobile feeding device 1002 and promptly transport the workpiece 300 to the host 200 for processing. Thus, the buffer device 100 continuously feeds the host 200.

[0050] According to the embodiments of the present invention, the buffer device 100, compared with the related art schemes that require an additional transition mechanism between the automatic loading / unloading device and the host 200 to transfer the workpiece 300, allows the material rack 2 to be movably disposed on the mounting frame 1 along the first and second directions. This enables the mounting frame 1 to directly move the material rack 2 to the position where it docks with the host 200 to transfer the workpiece 300 to the host 200 for processing. In this way, the mounting frame 1 can be placed close to the host 200, eliminating the need for an additional transition mechanism between the buffer device 100 and the host 200. This reduces the area occupied in the production workshop, improves space utilization, and also improves the loading / unloading efficiency of the host 200, which is conducive to maximizing production efficiency.

[0051] In some embodiments, reference Figure 2 The second position is located on the upper side of the bed 201, and the material rack 2 overlaps with the bed 201 in at least part in the second direction. In other words, the projection of the material rack 2 and the bed 201 in the horizontal plane overlaps with at least part. In this way, when the material rack 2 needs to be replenished, the material rack 2 can make room in the first position to make room for the self-moving feeding device 1002 to replenish the workpiece 300, thereby reducing obstacles on the walking channel 1003 of the self-moving feeding device 1002, thus facilitating the operation of the self-moving feeding device 1002 and helping to improve the replenishment efficiency of the buffer device 100 while reducing the space occupied by the buffer device 100.

[0052] According to some embodiments of the present invention, reference Figures 3-7The mounting frame 1 may include a main frame 101 and a first auxiliary support 103. The first auxiliary support 103 is movably mounted on the main frame 101 along a first direction, and the material rack 2 is movably mounted on the first auxiliary support 103 along a second direction. The main frame 101 is provided with a first driving mechanism 3, which is connected to the first auxiliary support 103 to drive the first auxiliary support 103 to translate along the first direction. The first auxiliary support 103 is provided with a first translation mechanism 4, which is connected to the material rack 2 to drive the second auxiliary support 23 to translate along the second direction. Thus, the overall structure is relatively simple and easy to manufacture and assemble.

[0053] For example Figure 2 As shown, the main frame 101 can be roughly formed as a cuboid frame. The main frame 101 is arranged adjacent to the bed 201 of the main machine 200. The first auxiliary support 103 is slidably arranged inside the main frame 101 in the vertical direction. The material rack 2 is slidably arranged inside the first auxiliary support 103 in the horizontal direction. The first drive mechanism 3 is arranged on the main frame 101. The first drive mechanism 3 is connected to the first auxiliary support 103 to drive the first auxiliary support 103 to move up and down in the vertical direction. The first translation mechanism 4 is connected to the material rack 2 to drive the second auxiliary support 23 to move horizontally in the horizontal direction. In this way, through the cooperation of the first auxiliary support 103 and the main frame 101 and the cooperation of the material rack 2 and the first auxiliary support 103, the material rack 2 can be sent to the first position to dock with the conveying component of the main machine 200 to transfer the workpiece 300, or the material rack 2 can be sent to the second position to receive the workpiece 300 conveyed by the moving feeding device 1002.

[0054] In some embodiments, the first translation mechanism 4 can be connected to the first drive mechanism 3 by a floating joint. This ensures that after the first auxiliary support 103 moves to a suitable position in the first direction under the drive of the first drive mechanism 3, the material rack 2 can move in the second direction under the drive of the first translation mechanism 4. This avoids the material rack 2 from colliding with the bed 201 of the host 200 when it moves in the second direction from a low position, such as the first position.

[0055] According to some embodiments of the present invention, reference Figures 3-8The material rack 2 may include a second auxiliary support 23, a frame 21, and a hopper mechanism 22. The second auxiliary support 23 is movably disposed on the first auxiliary support 103 along a second direction. A first translation mechanism 4 is connected to the second auxiliary support 23 to drive the second auxiliary support 23 to translate along the second direction. The frame 21 can be generally formed as a cuboid frame structure, disposed on the second auxiliary support 23, and the frame 221 can translate relative to the second auxiliary support 23 along a first direction. Both side walls of the frame 21 along a third direction are formed as flat plates. The hopper mechanism 22 is disposed within the frame 21 and can translate relative to the frame 21 along a second direction. The hopper mechanism 22 can be used to receive and store workpieces conveyed by the self-moving feeding device 1002 and to transfer workpieces to the main unit 200. The second auxiliary support 23 is provided with a second translation mechanism 6. The second translation mechanism 6 is adapted to drive the hopper mechanism 22 to translate relative to the frame 21 in the second direction. In this way, through the cooperation of the second auxiliary support 23 and the first auxiliary support 103, the entire rack 2 can be translated in the second direction. Through the cooperation of the frame 21 and the second auxiliary support 23, the entire frame 21 and the hopper mechanism 22 can be translated in the first direction, thereby sending the hopper mechanism 22 to a suitable height. Through the cooperation of the hopper mechanism 22 and the second translation mechanism 6, the hopper mechanism 22 can be sent to a suitable position in the horizontal direction.

[0056] Furthermore, there are two first auxiliary supports 103, which are located on opposite sides of the material rack 2 along a third direction. Each first auxiliary support 103 is located between the material rack 2 and the main frame 101. More specifically, the two first auxiliary supports 103 are located on opposite sides of the second auxiliary support 23 along a third direction. Each first auxiliary support 103 is located between the second auxiliary support 23 and the main frame 101. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0057] For example Figure 2 and Figure 3 As shown, the first auxiliary support 103 is roughly formed as a quadrilateral frame structure, and the second auxiliary support 23 is formed as a cuboid frame structure. The second auxiliary support 23 is located inside the main frame 101 and is spaced apart from the main frame 101. The two first auxiliary supports 103 are respectively located between the second auxiliary support 23 and the main frame 101 in two gaps in the third direction. The first auxiliary support 103 and the main frame 101 can be engaged in the upper limit in the second direction, and the second auxiliary support 23 and the first auxiliary support 103 can be engaged in the upper limit in the first direction. In this way, it can be ensured that the first auxiliary support 103 drives the material rack 2 to move up and down together in the first direction, while the second auxiliary support 23 can drive the frame 21 and the hopper mechanism 22 to move translationally together in the second direction.

[0058] According to some embodiments of the present invention, reference Figure 2 and Figure 3The first driving mechanism 3 can be one of a cylinder, an electric cylinder, a linear motor, or a lead screw drive mechanism. Taking a cylinder as an example, the bottom end of the first driving mechanism 3 is fixed to the main frame 101, and the top end of the piston rod of the first driving mechanism 3 is connected to the first auxiliary support 103. The piston rod can drive the first auxiliary support 103 to move in the vertical direction. The first translation mechanism 4 can also be one of a cylinder, an electric cylinder, a linear motor, or a lead screw drive mechanism. Taking a cylinder as an example, the first translation mechanism 4 can be horizontally fixed to the first auxiliary support 103, and the piston rod of the first auxiliary support 103 is connected to the second auxiliary support 23. In this way, the piston rod can drive the second auxiliary support 23 to move in the horizontal direction. Thus, the first driving mechanism 3 and the first translation mechanism 4 are widely available, easy to obtain, and have low cost. At the same time, they are easy to maintain later.

[0059] According to some embodiments of the present invention, the first auxiliary support 103 is slidably engaged with the main frame 101, the material rack 2 is slidably engaged with the first auxiliary support 103, and more specifically, the second auxiliary support 23 is slidably engaged with the first auxiliary support 103. This is beneficial to improving the stability of the movement of the material rack 2.

[0060] According to some embodiments of the present invention, reference Figure 2 and Figure 3 The first auxiliary support 103 is connected to the main frame 101 via a first sliding assembly. The first sliding assembly may include two first slide rails 102 and two first sliders 104. The two first slide rails 102 extend vertically and are positioned opposite each other and spaced apart along a second direction. The two first sliders 104 correspond one-to-one with the two first slide rails 102 and are slidably engaged. One of the first slide rails 102 and the first sliders 104 is located on the main frame 101, and the other is located on the first auxiliary support 103. For example, the first slide rail 102 may be located on the main frame 101 and the first slider 104 may be located on the first auxiliary support 103, or the first slide rail 102 may be located on the first auxiliary support 103 and the first slider 104 may be located on the main frame 101. In this way, the stability of the first auxiliary support 103 when moving along the first direction can be improved by sliding connection. At the same time, the structure is relatively simple and easy to assemble and maintain.

[0061] The second auxiliary support 23 and the first auxiliary support 103 are connected by a second sliding assembly. The second sliding assembly includes two second slide rails 25 and two second sliders 24. The second slide rails 25 extend along a second direction. The two second slide rails 25 can be arranged opposite each other and spaced apart along a first direction. The two second sliders 24 correspond one-to-one with the two second slide rails 25 and are adapted to each other. One of the second slide rails 25 and the second slider 24 is located on the first auxiliary support 103 and the other is located on the second auxiliary support 23. For example, the second slide rail 25 can be located on the first auxiliary support 103 and the second slider 24 can be located on the second auxiliary support 23, or the second slide rail 25 can be located on the second auxiliary support 23 and the second slider 24 can be located on the first auxiliary support 103. In this way, the stability of the second auxiliary support 23 when moving along the second direction can be improved by sliding cooperation. At the same time, the structure is relatively simple and easy to assemble and maintain.

[0062] In some embodiments, reference Figure 7 and Figure 8 The hopper mechanism 22 may include multiple sub-hopper mechanisms 221, which are arranged along a first direction. Each sub-hopper mechanism 221 can move relative to the frame 21 along a second direction. Each sub-hopper mechanism 221 is suitable for receiving and storing workpieces conveyed by the self-moving feeding device 1002 and transferring workpieces to the host machine 200. The second translation mechanism 6 can be detachably connected to any sub-hopper mechanism 221 to drive the corresponding sub-hopper mechanism 221 to translate along the second direction. When it is necessary to convey the workpiece 300 stored on any sub-hopper mechanism 221 to the host machine 200, the sub-hopper mechanism 221 can be moved along the first direction to a position flush with the second translation mechanism 6, and then the second translation mechanism 6 and the sub-hopper mechanism 221 can be connected by transmission. In this way, the workpiece 300 can be conveyed layer by layer, with a high degree of automation, which can improve the conveying efficiency of the workpiece 300.

[0063] Furthermore, each layer of sub-bin mechanism 221 includes a bin frame 2211 and a conveying mechanism 2213. The conveying mechanism 2213 is located on the bin frame 2211 and is used to support and transfer the workpiece 300. The bin frame 2211 is provided with a mating part 2212. The second translation mechanism 6 includes a driving member 61 and a push plate 62. The push plate 62 can be connected to the driving member 61 for transmission. The driving member 61 is used to drive the push plate 62 to translate along the second direction. The push plate 62 is suitable for separable engagement with the mating part 2212 of any layer of sub-bin mechanism 221. In this way, the movement is relatively simple and the reliability is high.

[0064] For example Figure 9As shown, the conveying mechanism 2213 includes a conveyor belt 2214 and a drive motor 2215. The conveying direction of the conveyor belt 2214 is parallel to the second direction. The output end of the drive motor 2215 is connected to one end of the conveyor belt 2214. The conveyor belt 2214 is located on the upper side of the hopper frame 2211. At least one end of the hopper frame 2211 along the third direction has a mating member 2212. The mating member 2212 is formed as a mating post, and the mating post extends along the third direction. The second translation mechanism 6 includes a drive member 61 and a push plate 62. The drive member 61 can be one of a cylinder, an electric cylinder, a linear motor, or a lead screw drive mechanism. The push plate 62 can be separable from the mating column in the first direction and limited in the second direction. In this way, when the workpiece 300 on any layer of sub-bin mechanism 221 is transported to the host machine 200, the sub-bin mechanism 221 can be moved along the first direction first, so that the mating part 2212 on the bin frame 2211 of the sub-bin mechanism 221 is limited in the push plate 62. Then, the drive member 61 drives the push plate 62 to move along the second direction to move the sub-bin mechanism 221 out of the frame 21. Finally, the conveyor belt 2214 transports the workpiece 300 to the host machine 200.

[0065] Furthermore, there can be multiple mating parts 2212, which can be spaced apart along the second direction. The push plate 62 has multiple limiting grooves 621 spaced apart along the second direction. The number of limiting grooves 621 is the same as the number of mating parts 2212 and corresponds one-to-one. Each mating part 2212 is suitable for being separably inserted into the corresponding limiting groove 621. Since the mating parts 2212 move up and down along the first direction with the hopper frame 2211 before being inserted into the limiting groove 621, the direction in which the mating parts 2212 are inserted into or pulled out of the limiting groove 621 is the first direction. Thus, by having multiple mating parts 2212 cooperate with the multiple limiting grooves 621 on the push plate 62, the stability and reliability of the sub-hopper mechanism 221 when moving along the second direction can be improved.

[0066] In some embodiments, reference Figure 8 A guide hole 211 is formed on the side wall of the frame 21, and the guide hole 211 extends along the second direction. The mating part 2212 is movably inserted through the guide hole 211 along the second direction, for example... Figure 8As shown, the frame 21 is generally formed into a cuboid structure. A guide hole 211 is formed on at least one side wall of the frame 21 along a third direction. The guide hole 211 penetrates the side wall of the frame 21 along the third direction and extends along the second direction. The mating part 2212 is formed into a column shape. The mating part 2212 is inserted into the guide hole 211 along the third direction. The mating part 2212 can move along the extension direction of the guide hole 211, thereby driving the sub-bin mechanism 221 to translate along the second direction. In this way, through the sliding engagement of the guide hole 211 and the mating part 2212, the movement of the sub-bin mechanism 221 in the second direction can be smoother and more reliable.

[0067] According to some embodiments of the present invention, reference Figures 5-7 The second auxiliary support 23 is also provided with a second lifting mechanism 5. The second lifting mechanism 5 is connected to the frame 21 to drive the frame 21 to move along the first direction. In this way, when the first driving mechanism 3 has raised the first auxiliary support 103 to the highest position and the frame 21 still has room to rise, or when the first driving mechanism 3 has not driven the first auxiliary support 103 to rise, the second lifting mechanism 5 can also drive the frame 21 to perform lifting and lowering movements to ensure that each layer of sub-bin mechanism 221 in the frame 21 can be raised and lowered to a suitable position to cooperate with the second translation mechanism 6, thereby completing the conveying of the workpiece 300.

[0068] According to some embodiments of the present invention, the mounting frame 1 is provided with a first stop assembly (not shown in the figure). The first stop assembly may include an upper stop and a lower stop. The upper stop and the lower stop can respectively determine the upper limit position and the lower limit position when the first auxiliary support 103 moves up and down in the first direction, thereby preventing the first auxiliary support 103 from detaching from the mounting frame 1 and ensuring the reliability of the movement of the first auxiliary support 103 and the material rack 2 in the first direction.

[0069] Similarly, a second stop assembly (not shown in the figure) may be provided on the first auxiliary support 103. The second stop assembly may include a first sub-stop and a second sub-stop. The first sub-stop and the second sub-stop can respectively determine the two limit positions of the second auxiliary support 23 when it makes a translational movement in the second direction, thereby preventing the second auxiliary support 23 from detaching from the first auxiliary support 103 and ensuring the reliability of the material rack 2's movement in the second direction.

[0070] The drilling apparatus 1004 according to a second aspect of the present invention is described below.

[0071] The drilling device 1004 according to an embodiment of the present invention may include: a host 200 and a cache device 100.

[0072] The main unit 200 includes a bed 201 and a conveying assembly mounted on the bed 201. A buffer device 100 is used to convey and receive workpieces to and from the main unit 200. The buffer device 100 includes a mounting frame 1 and a material rack 2. The material rack 2 is movably mounted on the mounting frame 1 along a first direction and a second direction. The material rack 2 can be used to store and transfer workpieces. The second direction is parallel to the direction in which the material rack 2 transfers workpieces; for example, the first direction can be vertical, and the second direction can be horizontal. The material rack 2 has a first position and a second position. In the first position, a second translation mechanism 6 drives the material rack 2 to convey and receive workpieces along the second direction. In the second position, the material rack 2 is adapted to receive workpieces from the self-moving feeding device 1002.

[0073] According to the present invention, by setting the buffer device 100 in the above embodiment, the workpiece loading efficiency of the drilling equipment 1004 is improved, while the space occupancy rate of the drilling equipment 1004 is reduced.

[0074] Further, refer to Figures 3-7 According to some embodiments of the present invention, reference is made to Figures 3-7 The mounting frame 1 may include a main frame 101 and a first auxiliary support 103. The first auxiliary support 103 is movably mounted on the main frame 101 along a first direction, and the material rack 2 is movably mounted on the first auxiliary support 103 along a second direction. The main frame 101 is provided with a first driving mechanism 3, which is connected to the first auxiliary support 103 to drive the first auxiliary support 103 to translate along the first direction. The first auxiliary support 103 is provided with a first translation mechanism 4, which is connected to the material rack 2 to drive the second auxiliary support 23 to translate along the second direction. Thus, the overall structure is relatively simple and easy to manufacture and assemble.

[0075] For example Figure 2 As shown, the main frame 101 can be roughly formed as a cuboid frame. The main frame 101 is arranged adjacent to the bed 201 of the main machine 200. The first auxiliary support 103 is slidably arranged inside the main frame 101 in the vertical direction. The material rack 2 is slidably arranged inside the first auxiliary support 103 in the horizontal direction. The first drive mechanism 3 is arranged on the main frame 101. The first drive mechanism 3 is connected to the first auxiliary support 103 to drive the first auxiliary support 103 to move up and down in the vertical direction. The first translation mechanism 4 is connected to the material rack 2 to drive the second auxiliary support 23 to move horizontally in the horizontal direction. In this way, through the cooperation of the first auxiliary support 103 and the main frame 101 and the cooperation of the material rack 2 and the first auxiliary support 103, the material rack 2 can be sent to the first position to dock with the conveying component of the main machine 200 to transfer the workpiece 300, or the material rack 2 can be sent to the second position to receive the workpiece 300 conveyed by the moving feeding device 1002.

[0076] In some embodiments, the first translation mechanism 4 can be connected to the first drive mechanism 3 by a floating joint. This ensures that after the first auxiliary support 103 moves to a suitable position in the first direction under the drive of the first drive mechanism 3, the material rack 2 can move in the second direction under the drive of the first translation mechanism 4. This avoids the material rack 2 from colliding with the bed 201 of the host 200 when it moves in the second direction from a low position, such as the first position.

[0077] refer to Figures 7-9 The material rack 2 may include a second auxiliary support 23, a frame 21, and a hopper mechanism 22. The second auxiliary support 23 is movably disposed on the first auxiliary support 103 along a second direction. A first translation mechanism 4 is connected to the second auxiliary support 23 to drive the second auxiliary support 23 to translate along the second direction. The frame 21 can be generally formed as a cuboid frame structure, disposed on the second auxiliary support 23, and the frame 221 can translate relative to the second auxiliary support 23 along a first direction. Both side walls of the frame 21 along a third direction are formed as flat plates. The hopper mechanism 22 is disposed within the frame 21 and can translate relative to the frame 21 along a second direction. The hopper mechanism 22 can be used to receive and store workpieces conveyed by the self-moving feeding device 1002 and to transfer workpieces to the main unit 200. The second auxiliary support 23 is provided with a second translation mechanism 6. The second translation mechanism 6 is adapted to drive the hopper mechanism 22 to translate relative to the frame 21 in the second direction. In this way, through the cooperation of the second auxiliary support 23 and the first auxiliary support 103, the entire rack 2 can be translated in the second direction. Through the cooperation of the frame 21 and the second auxiliary support 23, the entire frame 21 and the hopper mechanism 22 can be translated in the first direction, thereby sending the hopper mechanism 22 to a suitable height. Through the cooperation of the hopper mechanism 22 and the second translation mechanism 6, the hopper mechanism 22 can be sent to a suitable position in the horizontal direction.

[0078] In some embodiments, reference Figure 2 The second position is located on the upper side of the bed 201, and the material rack 2 overlaps with the bed 201 in at least part in the second direction. In other words, the projection of the material rack 2 and the bed 201 in the horizontal plane overlaps with at least part. In this way, when the material rack 2 needs to be replenished, the material rack 2 can make room in the first position to make room for the self-moving feeding device 1002 to replenish the workpiece 300, thereby reducing obstacles on the walking channel 1003 of the self-moving feeding device 1002, thus facilitating the operation of the self-moving feeding device 1002 and helping to improve the replenishment efficiency of the buffer device 100 while reducing the space occupied by the buffer device 100.

[0079] In some embodiments, when the rack 2 of the buffer device 100 conveys or receives workpieces to the host 200, the host 200 does not stop working. In this way, the operation of the buffer device 100 can be prevented from affecting the operation of the host 200, and production efficiency can be guaranteed.

[0080] The caching device 100 according to a third aspect of the present invention is described below.

[0081] The buffer device 100 according to an embodiment of the present invention can be used in a drilling device 1004. The drilling device 1004 may include a host 200 and a buffer device 100. The host 200 includes a bed 201 and a conveying assembly disposed on the bed 201. The buffer device 100 is used to convey and receive workpieces to the host 200.

[0082] The material rack 2 is movably mounted on the mounting frame 1. For example, the material rack 2 can be translatably mounted on the mounting frame 1 along a first direction and a second direction, wherein the first direction is the up-down direction and the second direction is the left-right direction. The material rack 2 has a first position and a second position on the mounting frame 1. When it is necessary to transfer a workpiece 300 to the host machine 200, the material rack 2 is controlled to move from the second position to the first position. After the workpiece 300 is transferred, the material rack 2 can be controlled to return to the second position to receive a replenished workpiece 300 from the mobile feeding device 1002. This cycle continues, and the material rack 2 can receive and temporarily store the workpiece 300 transported by the mobile feeding device 1002 and promptly transport the workpiece 300 to the host machine 200 for processing. Thus, the buffer device 100 continuously feeds the host machine 200.

[0083] According to the embodiments of the present invention, the buffer device 100, compared with the related art schemes that require an additional transition mechanism between the automatic loading / unloading device and the host 200 to transfer the workpiece 300, allows the material rack 2 to be movably mounted on the mounting frame 1. This enables the mounting frame 1 to directly move the material rack 2 to a position where it docks with the host 200 to transfer the workpiece 300 to the host 200 for processing. In this way, the mounting frame 1 can be placed close to the host 200, eliminating the need for an additional transition mechanism between the buffer device 100 and the host 200. This reduces the area occupied in the production workshop, improves space utilization, and also improves the loading / unloading efficiency of the host 200, which is conducive to maximizing production efficiency.

[0084] In some embodiments, reference Figure 2The second position is located on the upper side of the bed 201, and the material rack 2 overlaps with the bed 201 in at least part in the second direction. In other words, the projection of the material rack 2 and the bed 201 in the horizontal plane overlaps with at least part. In this way, when the material rack 2 needs to be replenished, the material rack 2 can make room in the first position to make room for the self-moving feeding device 1002 to replenish the workpiece 300, thereby reducing obstacles on the walking channel 1003 of the self-moving feeding device 1002, thus facilitating the operation of the self-moving feeding device 1002 and helping to improve the replenishment efficiency of the buffer device 100 while reducing the space occupied by the buffer device 100.

[0085] Furthermore, the second position is higher than the first position. The second position is used for loading or releasing the rack 2 by the buffer device 100. Since the second position is higher than the first position, the rack 2 can make room for the space at the first position, so as to make room for the self-moving feeding device 1002 to replenish the workpiece 300 of the rack 2, thereby reducing obstacles on the walking channel 1003 of the self-moving feeding device 1002, so as to better load the workpiece for the buffer device 100, or release the rack 2 onto the bed 201.

[0086] The following is for reference. Figure 1 and Figure 2 An automated processing production line 1000 according to an embodiment of a fourth aspect of the present invention is described.

[0087] An automated processing production line 1000 according to an embodiment of the present invention includes: a multi-row sub-production line 1001 and a self-moving feeding device 1002.

[0088] The multi-row sub-production lines 1001 can be arranged at intervals along the second direction. A walking channel 1003 is defined between two adjacent rows of sub-production lines 1001. Each row of sub-production lines 1001 includes multiple drilling devices 1004 as described in the above embodiments. Multiple drilling devices 1004 belonging to the same row of sub-production lines 1001 are arranged along a third direction, which is perpendicular to the first direction and perpendicular to the second direction. The self-moving feeding device 1002 can move on the ground. For example, the self-moving feeding device 1002 can be an AGV (Automated Guided Vehicle). The self-moving feeding device 1002 can move along the third direction within the walking channel 1003. The self-moving feeding device 1002 is adapted to transfer the workpiece 300 to be processed to the buffer device 100. Then, the buffer device 100 transfers the workpiece 300 to the host 200 for processing. Optionally, the buffer device 100 can also transfer the processed workpiece 300 to the self-moving feeding device 1002.

[0089] According to the embodiments of the present invention, the automated processing production line 1000 is equipped with a buffer device 100 as described in the above embodiments for each drilling device 1004, which reduces the floor space of the entire production line and improves the feeding efficiency of the entire production line.

[0090] The working principle of the automated processing production line 1000 according to an embodiment of the present invention is described below:

[0091] When the buffer device 100 does not need to transfer the workpiece 300 to the host machine 200, to avoid interference or collision between the buffer device 100 and the self-moving feeding device 1002 in the travel channel 1003, the first drive mechanism 3 can be controlled to drive the first auxiliary support 103 to move upwards to a position flush with the top of the bed 201 of the host machine 200. Then, the first translation mechanism 4 can be controlled to drive the second auxiliary support 23 to move the material rack 2 along the second direction to the upper side of the bed 201, thereby clearing the travel channel 1003. Finally, after the material rack 2 is in place, the control module sends a command to the self-moving feeding device 1002 to ensure that the self-moving feeding device 1002 can pass safely. At the same time, in this state, the self-moving feeding device 1002 can transfer the workpiece 300 to the buffer device 100.

[0092] When the buffer device 100 needs to transfer the workpiece 300 to the host 200, the material rack 2 is moved from the upper side of the bed 201 and returned to its initial position on the mounting frame 1 through the cooperation of the first drive mechanism 3 and the first translation mechanism 4. At this time, the material rack 2 can block the travel channel 1003 of the self-moving feeding device 1002. Then, the control module controls the second lifting mechanism 5 to drive the frame 21 to rise, so that the mating part 2212 of the sub-material bin mechanism 221 of the target layer is limited to the push plate 62 of the second translation mechanism 6. Then, the second translation mechanism 6 is controlled to drive the sub-material bin mechanism 221 to move along the second direction and dock with the base 203 or the receiving track of the host 200. Finally, the conveying mechanism 2213 on the sub-material bin mechanism 221 is controlled to output the workpiece 300 to the host 200. At the same time, in this state, the self-moving feeding device 1002 is in a prohibited passage state to prevent collisions.

[0093] Optionally, position detection devices can be provided for the first drive mechanism 3, the first translation mechanism 4, the second lifting mechanism 5, and the second translation mechanism 6 respectively. For example, the position detection device can be a magnetic sensor. This allows the control module to determine the position of the material rack 2 by acquiring the movement positions of the first drive mechanism 3, the first translation mechanism 4, the second lifting mechanism 5, and the second translation mechanism 6, thereby providing a basis for the passage control of the self-moving feeding device 1002.
