[0081] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0082] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0083] Please refer to Figure 1-11 This utility model provides a workstation.

[0084] refer to Figure 1 As shown, the workstation provided by this utility model includes a frame 100, a working mechanism 300, and a multi-axis mounted robot 400. The multi-axis mounted robot 400 and the working mechanism 300 are mounted on the frame 100 and integrated into a workstation.

[0085] refer to Figure 2 The working mechanism 300 includes a vision unit 301 and / or a processing unit 302. The working mechanism 300 can perform visual inspection and / or processing on the workpiece mounted on the mounting end of the multi-axis mounting robot 400.

[0086] The working mechanism 300 may include only the vision unit 301 or the processing unit 302, or it may have both the vision unit 301 and the processing unit 302. The vision inspection unit is mainly used for visual inspection of workpieces, such as inspecting the condition of the workpiece surface, and / or visually positioning the workpiece.

[0087] The visual inspection performed by the vision unit 301 can be to inspect the surface of the workpiece, to perform visual positioning of the workpiece, or both.

[0088] The processing unit 302 can be an assembly unit, a cleaning unit, or other processing unit that processes workpieces. The cleaning unit includes one or more of a wiping mechanism, a blowing mechanism, a dry ice mechanism, and a plasma mechanism. The cleaning unit can clean the workpiece.

[0089] refer to Figure 16 As shown, the cleaning unit may include a sponge 3021, an eraser 3022, a brush 3023, a polishing wheel 3024, and a rotating module 3025. The rotating module 3025 can be driven to rotate, which can make the sponge 3021, eraser 3022, brush 3023, and polishing wheel 3024 rotate, so as to flexibly replace the cleaning head.

[0090] The processing unit 302 can perform one or more of the following: wiping, blowing, dry ice treatment, and plasma treatment. Dry ice treatment utilizes compressed air to propel high-speed jets of extremely low-temperature dry ice particles onto the workpiece surface. The kinetic energy of the high-speed impact breaks down the contaminant layer, the thermal shock caused by the ultra-low temperature embrittles and cracks the contaminant layer, and the instantaneous sublimation of the dry ice generates a massive volume expansion that peels off the contaminant layer, achieving a highly efficient, wear-free, and residue-free cleaning effect. Plasma treatment reconstructs surface properties at the atomic / molecular level, achieving a transformation from "inert" to "active," with effects far exceeding traditional solvent cleaning or polishing.

[0091] The "processed workpiece" referred to in this utility model refers to the workpiece after being processed by the working mechanism 300. It can be a workpiece that has undergone visual inspection and positioning processing by the vision unit, or a workpiece that has only undergone cleaning or other operations processing by the processing unit 302, or a workpiece that has been processed by both the vision inspection unit and the processing unit 302 at the same time.

[0092] The processing of the workpiece by the working mechanism referred to in this utility model may be the processing by only the vision inspection unit, such as the vision unit performing visual inspection and positioning processing on the workpiece; it may also be the processing by only the processing unit 302, such as the cleaning processing of the workpiece by the processing unit 302; or it may be the processing by both the vision inspection unit and the processing unit 302.

[0093] refer to Figure 17 and Figure 1-11 The multi-axis robot 400 includes a robotic arm body and an output joint 42, which is connected to the tail end of the robotic arm body.

[0094] refer to Figure 3 , Figure 6 The output joint 42 has a mounting end 4211, which is the end that mounts the workpiece and can be used to mount the workpiece.

[0095] refer to Figure 3 The main body of the robotic arm includes a mounting end and a swing arm 4a connected between the mounting end and the output joint 42. The swing arm 4a can drive the output joint 42 to swing relative to the mounting end, so that the mounting end 4211 of the output joint 42 moves closer to or further away from the working mechanism 300.

[0096] This utility model integrates the working mechanism 300 and the multi-axis robot 400 into a single workstation via a frame, reducing the involvement of humans in the production process. It enables automated collaborative work between the multi-axis robot 400 and the working mechanism 300, completely replacing manual operation and reducing labor costs.

[0097] This utility model's workstation uses a multi-axis loading robot 400 to load workpieces. The swing arm of the multi-axis loading robot 400 moves the loaded workpiece, enabling direct or indirect loading and unloading. Furthermore, the swinging of the multi-axis loading robot 400's arm allows the loading end to approach the working mechanism 300, aligning the workpiece loaded at the loading end with the working mechanism 300, which then processes the workpiece. The multi-axis loading robot 400 and the working mechanism 300 can work collaboratively, greatly improving work efficiency.

[0098] refer to Figure 3 and Figure 17 In a preferred embodiment, the main body of the robotic arm includes a lifting arm 10, which moves up and down in the vertical direction, causing the output joint 42 to move closer to or further away from the working mechanism 300 in the vertical direction.

[0099] refer to Figure 3 and Figure 17 The robotic arm body has multiple swing arms 4a, which are stacked vertically within the upper frame 100. The rotation axis of each swing arm 4a extends vertically along axis c. The swing arms 4a are distributed sequentially from the front end (the end where the robot is mounted) to the rear end (the mounting end) of the multi-axis mounted robot 400, with their length direction being horizontal. This invention's multi-axis mounted robot 400 occupies relatively little space in terms of height; the height from the bottom to the top of the swing arms is less than 500mm, and can even be less than 300mm, achieving a larger working space while occupying less space.

[0100] refer to Figure 3 , Figure 6 ,and Figure 17 At least one swing arm 4a extends horizontally along its length, and the swing arm can drive the output joint 42 to move horizontally toward or away from the working mechanism 300. When it is necessary to receive or transfer materials, the swing arm can drive the output joint 42 to move horizontally away from the working mechanism 300. When the working mechanism 300 needs to process the workpiece, the swing arm can drive the output joint 42 to move horizontally toward the working mechanism 300, with the mounting end opposite to the working mechanism 300.

[0101] In this embodiment, the swing arm 4a extends horizontally and drives the output joint 42 to move horizontally, thus limiting the swing arm's range of motion to the horizontal direction and reducing its vertical space occupation. Since the swing arm does not occupy vertical space, the working mechanism 300 and the multi-axis mounted robot 400 can be vertically spaced on the frame 100. In other words, from the perspective of the workstation's height, one of the working mechanism 300 and the multi-axis mounted robot 400 is above the other; that is, the working mechanism 300 can be above the multi-axis mounted robot 400 (including directly above and to the side), or the multi-axis mounted robot 400 can be above the working mechanism 300 (including directly above and to the side). With the working mechanism 300 and the multi-axis mounted robot 400 vertically spaced on the frame 100 working together, the swing arm can drive the mounting end to move horizontally, making the workstation layout more rational and compact.

[0102] refer to Figure 6 When the swing arm drives the mounting end 4211 to move horizontally away from the working mechanism 300, the workpiece can be mounted by loading and unloading.

[0103] refer to Figure 3 The swing arm drives the mounting end 4211 to move horizontally closer to the working mechanism 300. When working with the working mechanism 300, the working mechanism 300 processes the workpiece mounted on the mounting end. The space occupied by the swing arm movement of the multi-axis mounting robot 400 and the space occupied by the working mechanism 300 can be reasonably arranged, resulting in higher work efficiency and a smaller workstation footprint.

[0104] refer to Figure 17 In a preferred embodiment, the swing arm includes a first swing arm 20, a second swing arm 30, a robotic arm, and a robotic arm 40. The first swing arm 20, the second swing arm 30, and the robotic arm 40 are stacked vertically. The lifting arm 10 is connected to the first swing arm 20. The second swing arm 30 swings relative to the first swing arm 20, and the robotic arm 40 swings relative to the second swing arm 30. The rotation axes of the first swing arm 20, the second swing arm 30, and the robotic arm 40 extend vertically. The first swing arm 20, the second swing arm 30, and the robotic arm 40 are distributed sequentially from the head end to the tail end of the robotic arm. The output joint 42 is located at the tail end of the robotic arm 40. This allows the multi-axis robotic arm to swing at multiple angles, resulting in a more compact structure and more flexible use.

[0105] refer to Figure 17In a preferred embodiment, the lifting arm 10 is connected to the head end of the first swing arm 20, the first swing arm 20 is connected to the lifting arm 10 through the first swing arm joint, the head end of the second swing arm 30 is connected to the tail end of the first swing arm 20 through the second swing arm joint, and the head end of the robotic arm 40 is connected to the tail end of the second swing arm 30 through the robotic arm joint. The pivots of the first swing arm 20, the second swing arm 30, and the robotic arm 40 are located in the first swing arm joint, the second swing arm joint, and the robotic arm joint, respectively. The pivots of the first swing arm 20, the second swing arm 30, and the robotic arm 40 are hollow structures. Cables pass through the lifting arm 10, the pivot of the first swing arm 20, the pivot of the first swing arm 20, the pivot of the second swing arm 30, the second swing arm 30, and the pivot of the robotic arm 30 in sequence and extend into the robotic arm 40.

[0106] refer to Figure 18 Compared to traditional four-axis systems, it offers a larger workspace and occupies less space; compared to traditional six-axis systems, the workspace is comparable, but the space occupied is even smaller. This significantly reduces the size of the workstation, making the overall workstation more compact. The workspace and space occupied by a traditional four-axis system are as follows... Figure 18 As shown in Figure A, the workspace and footprint of a traditional six-axis system are as follows: Figure 18 As shown in Figure B, the working space and occupied space of the robot arm of this utility model are as follows. Figure 18 As shown in C.

[0107] refer to Figure 17 and Figure 20 ,and Figure 22 In the preferred embodiment, the axis c of the swing arm is not parallel to the axis of the output joint, and the length direction of the swing arm connected to the output joint is perpendicular to the axis of the output joint. The axis of the output joint is also the first axis a, so that the output joint can provide rotation in other directions to flexibly adjust the position and direction of the mounting end 4211.

[0108] refer to Figure 19-22In a preferred embodiment, the swing arm connected to the output joint is called the robotic arm 40. The output end of the output joint 42 is provided with an output portion 421. The output portion 421 itself can be a mounting end, or the output portion 421 can be connected to a mounting end 4211. The robotic arm 40 includes a main body 4001, a first protrusion 4002, and a second protrusion 4003. The first protrusion 4002 and the second protrusion 4003 extend in the same direction relative to the main body 4001. The first protrusion 4002 and the second protrusion 4003 are spaced apart, such that the main body 4001, the first protrusion 4002, and the second protrusion 4003 are spaced apart. A joint mounting position 4004 is formed between 003. The output joint 42 is connected to the first protrusion 4002 and the second protrusion 4003 on both sides, respectively. The output joint 42 is installed in the joint mounting position 4004. A flip motor 404 is installed inside the robotic arm 40. A transmission space 402 is provided on one side of the robotic arm 40. A transmission mechanism 41a is installed in the transmission space 402. The transmission mechanism 41a is connected to the output joint 42 and the flip motor 404, respectively, and is used to drive the output joint 42 to rotate relative to the robotic arm 40 around the first rotating axis a. An output part 421 that rotates around the second rotating axis b is provided on the output joint 42. The first rotating axis and the second rotating axis are not parallel. Furthermore, the first rotating axis a and the second rotating axis b are perpendicular.

[0109] In this invention, when the output joint rotates relative to the main body of the robotic arm 40 around the first pivot a, the orientation of the mounting end can be changed, allowing the mounting end to face the working mechanism 300 and cooperate with the working mechanism 300 to process the workpiece. When there are two mounting robots 400, their mounting ends can rotate to face each other, realizing the transfer of workpieces between the two mounting robots 400. The output part 421 can rotate around the second pivot b, realizing the rotation of the workpiece at the mounting end, thus better realizing the processing of the workpiece.

[0110] The workstation provided by this utility model enables a compact multi-axis robot to rotate in multiple directions, making its movement more flexible and convenient, while occupying less space.

[0111] The main body 4001, the first protrusion 4002, and the second protrusion 4003 form a recessed joint mounting position 4004 for mounting the output joint, making the structure more compact. At the same time, the transmission mechanism 41a is set on one side of the robotic arm 40, so that the transmission space can provide rotational power for the output joint mounted in the joint mounting position 4, while making the structure more compact.

[0112] refer to Figure 19-22In a preferred embodiment, the robotic arm 40 has a transmission space 402 on one side and a wiring space 401 on the other side. A cable 50 is installed in the wiring space 401. The robotic arm 40 also has a receiving cavity 403 located between the wiring space 401 and the transmission space 402. A drive and flip motor 404 is installed in the receiving cavity 403. The drive includes a first drive and a second drive. The first drive is connected to the flip motor 404, and the second drive is connected to the transmission motor. The receiving cavity 403 communicates with the transmission space 402. The input end of the transmission mechanism located in the transmission space 402 is connected to the flip motor 404 located in the receiving cavity 403, and the output end is connected to the output joint 42. The receiving cavity 403 communicates with the wiring space 401. A portion of the cable powers the flip motor 404 in the receiving cavity 403, and a portion enters the wiring space 401 from the receiving cavity 403, then exits the wiring space 401 and connects to the output part 421 of the output joint 42. By setting up transmission spaces 402 and wiring spaces 401 on both sides and setting up a receiving cavity 403 in the middle, the motor, transmission mechanism and wiring can be reasonably arranged, enabling multi-axis rotation in a compact structure and improving the flexibility of the robotic arm.

[0113] refer to Figure 19-22 In a preferred embodiment, the robotic arm 40 has a main cover 4031 that can close the opening of the receiving cavity 403. Opening the cover facilitates the installation, maintenance, and replacement of the driver and the tilting motor 404, while also allowing for better cable routing. After installation, closing the opening of the receiving cavity 403 with the main cover 4031 provides better waterproofing and dustproofing. In this embodiment, the transmission mechanism is a synchronous pulley transmission mechanism or a gear transmission mechanism.

[0114] refer to Figure 19-22 In a preferred embodiment, the openings of both the wiring space 401 and the transmission space 402 are arranged facing outwards. In this embodiment, "outwards" refers to... Figure 20 and 22 As shown, the opening directions of the accommodating cavity 403, the wiring space 401, and the transmission space 402 are all different, which can save space and facilitate the maintenance of wiring and transmission mechanisms.

[0115] refer to Figure 19-22 In a preferred embodiment, the robotic arm 40 has a first side cover 4011 and a second side cover (not shown) that can close the opening of the wiring space 401 and the opening of the transmission space 402, which can facilitate installation and provide waterproof and dustproof protection.

[0116] refer to Figure 19-22In a preferred embodiment, the joint mounting position 4004 is located between the transmission space 402 and the wiring space 401. The wiring space 401 extends from the main body 4001 to the first protrusion 4002, and the transmission space 402 extends from the main body 4001 to the second protrusion 4003. The receiving cavity 403 is disposed on the main body 4001. In this embodiment, the robotic arm 40 has a recessed position for mounting the output joint 42. Simultaneously, the wiring space 401 and the transmission space 402 are formed by utilizing the first protrusion 4002 and the second protrusion 4003 on both sides of the joint mounting position 4004. The transmission and wiring within the main body 4001 are transmitted to the output joint 42 through the first protrusion 4002 and the second protrusion 4003. The structure is very compact, with high space utilization. This results in better dynamic response and more sensitive reaction when the robotic arm changes position.

[0117] refer to Figure 3-4 and Figure 6-7 The working mechanism 300 and the multi-axis robot 400 are mounted on the frame 100 at vertical intervals, meaning that from the height of the workstation, one of the working mechanism 300 and the multi-axis robot 400 is above the other. (Reference) Figure 3 This can be because the working mechanism 300 is located above (either directly above or to the side above) the multi-axis robot 400, for reference. Figure 6-7 Alternatively, the multi-axis robot 400 can be positioned above (directly above and to the side above) the working mechanism 300. This allows for a more compact and rational workstation layout, without occupying too much horizontal or vertical space. The workstation of this invention integrates both the multi-axis robot 400 and the working mechanism 300 onto the frame 100, and the cooperative operation of the multi-axis robot 400 and the working mechanism 300 is completed within the upper frame 102, resulting in a more compact workstation structure.

[0118] refer to Figure 3-4 The frame 100 of this invention may include a lower frame 103 and an upper frame 102, which are separated by a partition 104. The swing arm 4a and output joint of the working mechanism 300 and the multi-axis mounted robot 400 are located within the upper frame 102. The lower frame 103 is equipped with electrical components connected to the working mechanism 300 and the multi-axis mounted robot 400. The swing arm 4a swings within the space formed by the upper frame 102. The mounting positions of the working mechanism 300 and the multi-axis mounted robot 400 on the upper frame 102 are arranged vertically at intervals.

[0119] refer to Figure 1-9In a preferred embodiment, the working mechanism 300 is suspended above the upper frame 102, while the swing arm 4a and output joint 42 are located below the upper frame 102. The robot 400 is positioned below the working mechanism 300. The swing arm 4a of the robot 400 can drive the output joint 42 horizontally towards the working mechanism 300 to handle the workpiece; the swing arm 4a can also drive the output joint 42 horizontally away from the working mechanism 300 to perform loading, unloading, or transfer operations. The working mechanism 300 is suspended above the upper frame 102, while the swing arm and output joint are located below the upper frame 102, maximizing the use of the workstation's vertical space and minimizing its footprint.

[0120] refer to Figure 5 In a preferred embodiment, when the lifting arm 10 carrying the robot 400 is retracted, it can be partially or completely embedded in the lower frame 103, so that the lifting arm 10 does not occupy the working space of the upper frame 102, thereby enabling the upper suspended working mechanism 300 of the upper frame 102 to also be structurally compact in the vertical direction.

[0121] refer to Figure 3 When the lifting arm of the robot 400 is extended, it can be inserted into the upper frame 102, driving the mounting end to move closer to or further away from the working mechanism 300 in the vertical direction, so as to cooperate well with the working mechanism 300 in working.

[0122] When the lifting arm of the multi-axis robot 400 of this invention is retracted, it can be partially or completely embedded in the lower frame 103, allowing the multi-axis robot 400 to achieve a lifting effect without excessively occupying the working space of the upper frame 102. The height of the multi-axis robot 400's arm in the working space of the upper frame 102 can be less than 500mm, or even less than 300mm. This results in a larger working space in the upper frame 102 while occupying less space, leading to a higher space utilization rate for the upper frame 102.

[0123] refer to Figure 1-6 , Figure 8-9 , Figure 11In a preferred embodiment, the workstation may include a picking robot 200 that cooperates with the multi-axis mounted robot 400 to transfer workpieces. Here, "cooperative transfer" can refer to the picking robot 200 and the multi-axis mounted robot 400 directly cooperating to transfer workpieces, or it can refer to the picking robot 200 and the multi-axis mounted robot 400 indirectly cooperating to transfer workpieces through a transfer area. The picking robot 200 is mounted on the upper frame 102 via its fixing part 201. By integrating the multi-axis mounted robot 400, the picking robot 200, and the working mechanism 300 onto a single frame 100, a more integrated and compact structure is achieved. The picking robot 200's picking arm can swing between the inside and outside of the upper frame 102, realizing the transfer of workpieces outside the upper frame 102 to the inside of the upper frame 102. By having the picking robot 200 extend outside the frame 100 to pick up materials, this utility model can reduce the space required for the horizontal swing of the arm of the carrying robot 400. At the same time, by having the picking robot 200 transfer workpieces, workpieces outside the workstation can be transferred to the workstation without occupying processing time, which can save the volume of the workstation's loading and unloading mechanism.

[0124] refer to Figure 1-6 , Figure 8-9 , Figure 10-11 ,and Figure 12-15 In a preferred embodiment, the material handling robot 200 can be used for loading and unloading. The material handling robot 200 includes a fixed part 201, a connecting arm, and a material handling arm 204 connected in sequence. The material handling arm 204 has a material handling end 2041, which is mainly used to carry the workpiece 700.

[0125] The fixing part 201 is used to fix the picking robot 200, which can fix the picking robot 200 on the frame 100.

[0126] The connecting arm swings relative to the fixed part 201, thereby driving the material handling arm 204 to swing. (Reference) Figure 5 The swinging of the connecting arm allows the picking arm 204 to move in both the x and z directions of the workstation. In this embodiment, the x-direction refers to the direction in which the workpiece can be transferred within the frame 100, for example, the direction in which the workpiece is transferred from outside the frame 100 to inside the frame 100; or, for example, the direction in which the workpiece is transferred within the frame 100. (Reference) Figure 1-6 The material handling robot 200 can be a three-axis robot. (Reference) Figure 11 The material handling robot 200 can also be a four-axis robot.

[0127] refer to Figure 4-5 , Figure 12-15In a preferred embodiment, the material handling robot 200 includes a first connecting arm 202 connected to the fixed part 201 and a second connecting arm 203 connected to the material handling arm 204. The first connecting arm 202 connected to the fixed part 201 moves relative to the fixed part 201 in the x and z directions, thereby enabling the material handling arm 204 to move in the x and z directions of the workstation.

[0128] This invention allows for direct loading and unloading of workpieces via a combination of a picking robot 200 and a multi-axis loading robot 400. For example, the picking end of the picking robot 200 can rotate to transfer workpieces to the multi-axis loading robot 400. The picking robot 200 can also move workpieces outside the frame 100 to a transfer area inside the frame 100 near the multi-axis loading robot 400, allowing the multi-axis loading robot 400 to directly load or unload workpieces from the transfer area. By combining the picking robot 200 and the multi-axis loading robot 400, this invention saves time on loading and unloading for the multi-axis loading robot 400, improving workpiece processing efficiency. Furthermore, the picking robot 200 can transfer workpieces from outside the workstation to inside without interrupting processing time, saving space required for loading and unloading mechanisms within the workstation.

[0129] refer to Figure 1 and Figure 5 In a preferred embodiment, the connecting arm drives the picking arm 204 to move along the x and z directions of the workstation. When the picking robot 200 and the multi-axis mounting robot 400 transfer workpieces, the picking robot 200 rotates until its picking end 2041 is opposite to the mounting end 4211 of the multi-axis mounting robot 400, so that the picking robot 200 and the multi-axis mounting robot 400 can transfer workpieces.

[0130] refer to Figure 4-5 , Figure 12-15In a preferred embodiment, the fixing part 201, the first connecting arm 202, the second connecting arm 203 and the picking arm 204 are connected in sequence, and the fixing part 201 and the second connecting arm 203 are respectively rotatably connected to the two ends of the first connecting arm 202. The first connecting arm 202 includes a first end 202a and a second end 202b. The first end 202a of the first connecting arm 202 is connected to the second connecting arm 203, and the second end 202b of the first connecting arm 202 is connected to the fixing part 201. The second connecting arm 203 includes a first end 203a and a second end 203b. The first end 203a of the second connecting arm 203 is connected to the picking arm 204, and the second end 203b of the second connecting arm 203 is connected to the first connecting arm 202. The picking arm 204 includes a picking end 204a and a connecting end 204b. The connecting end 204b is connected to the second connecting arm 203. The picking end 204a is the end away from the connecting end 204b. The fixing part 201 includes a first end 201a and a second end 201b. The first end 201a of the fixing part 201 is connected to the first connecting arm 202, and the second end 201b of the fixing part 201 is the end away from the first end 201a.

[0131] refer to Figure 14 The first connecting arm 202 can rotate more than 360° relative to the fixed part 201, resulting in a large range of space for the second connecting arm 203 and the picking arm 204 to move as a whole. The second connecting arm 203 can rotate more than 360° relative to the first connecting arm 202, resulting in a large range of space for the picking arm 204 to move. The picking arm 204 can rotate more than 360° relative to the second connecting arm 203. The axial rotation axes of the first connecting arm 202, the second connecting arm 203, and the picking arm 204 are parallel.

[0132] refer to Figure 12-14In a preferred embodiment, the fixing part 201 is connected to the side of the first connecting arm 202 away from the second connecting arm 203. The first connecting arm 202 and the picking arm 204 are connected to the same side of the second connecting arm 203, making the swing arm more compact. At the same time, the length of the second connecting arm 203 is greater than the length of the first connecting arm 202, so that the rotation of the second connecting arm 203 in any state is not hindered by the picking arm 204. There is a rotational space between the first end 203a and the second end 203b of the second connecting arm 203, through which the second end 202b of the first connecting arm 202 can pass. When the second connecting arm 203 rotates, the second end 202b of the first connecting arm 202 can pass through this rotational space. The first connecting arm 202 and the picking arm 204 never come into contact, and the rotation of the second connecting arm 203 is not hindered. This allows the rotation angle range of the second connecting arm 203 relative to the first connecting arm 202 in any state to be greater than 360°. This results in the picking robot 200 having a compact structure, occupying little space, and having a large effective working space for flexible operation.

[0133] refer to Figure 13 When the material handling robot 200 rotates to its retracted state, the second connecting arm 203 can swing to overlap with the second end 202b of the first connecting arm 202. The first connecting arm 202 substantially overlaps one side of the second connecting arm 203 in the length direction, so that the first end 202a, the second end 202b of the first connecting arm 202 and the material handling arm 204 are sequentially arranged on the same side of the second connecting arm 203 facing the fixing part 201 along the length direction of the second connecting arm 203. The first connecting arm 202 can rotate to overlap with the second end 201b of the fixing part 201, and the fixing part 201 substantially overlaps one side of the first connecting arm 202 in the length direction. When the material handling robot 200 is not working, it can be retracted into a more compact structure, without occupying much space in the workstation.

[0134] refer to Figure 13 In the retracted state, where the first connecting arm 202 substantially overlaps one side of the second connecting arm 203 along its length, the first connecting arm 202 can rotate more than 360° around the fixed part 201. This allows the second connecting arm 203 and the picking arm 204 to rotate more than 360° around the fixed part 201. When a large effective space is not required, the picking robot 200 can be flexibly adjusted to a retracted state. In this state, the first connecting arm 202 substantially overlaps one side of the second connecting arm 203 along its length, and movement is achieved by rotating the first connecting arm 202, saving space. The picking robot 200 of this invention can flexibly adjust its effective working space and occupied space.

[0135] refer to Figure 15In a preferred embodiment, the fixing part 201 and the second connecting arm 203 are connected to the same side of the first connecting arm 202. In the retracted state, the first connecting arm 202 can swing to overlap with the second end of the fixing part 201, so that the first end and the second end of the fixing part 201 and the first end of the second connecting arm 203 are sequentially arranged on the same side of the first connecting arm 202 along the length direction of the first connecting arm 202. When the picking robot 200 is not working, it can be retracted into a more compact structure, without occupying much space in the workstation. There is a second rotation space between the first end 201a of the fixing part 201 and the first end 203a of the second connecting arm 203, through which the second end 201b of the fixing part 201 can pass. When the first connecting arm 202 rotates, the second end 201b of the fixing part 201 can pass through the second rotation space, so that the rotation angle range of the first connecting arm 202 in any state can be greater than 360°. There is a third transmission space between the connecting end 204b of the picking arm 204 and the second end 202b of the first connecting arm 202, through which the picking end 204a can pass. In the retracted state, the picking end 204a can retract into the third transmission space.

[0136] refer to Figure 1-4 , Figure 6-11 In a preferred embodiment, the multi-axis mounted robot 400 referred to in this utility model may have multiple components, including a first multi-axis mounted robot 400a and a second multi-axis mounted robot 400b.

[0137] refer to Figure 8 The first multi-axis loading robot 400a and the second multi-axis loading robot 400b can rotate until their output joints are facing each other, enabling workpiece transfer between the two loading robots 400. This allows one multi-axis loading robot 400 to load or unload workpieces while its loading end is away from the working mechanism 300, while the workpiece loaded by the other multi-axis loading robot 400 cooperates with the working mechanism 300 to process the workpiece, improving the workstation's efficiency and the flexibility of loading and unloading.

[0138] Furthermore, the workpiece transfer between the two carrying robots 400 can also realize the workpiece reversal during transfer, allowing the inspection surface of the carried workpiece to be reversed, enabling the working mechanism 300 to process different surfaces of the workpiece, and realizing multiple possibilities for flexible operation of the workstation. Specifically: after the first multi-axis carrying robot 400a carries a workpiece, its carrying end can be rotated so that the first part of the workpiece's surface faces the working mechanism 300, so that the working mechanism 300 processes the first part of the workpiece's surface (including processing by the vision unit 301 and / or the processing unit 302). The carrying end of the first multi-axis carrying robot 400a can also be rotated to transfer the workpiece with the first part of its surface processed to the second multi-axis carrying robot 400b. After receiving the workpiece transferred by the first multi-axis carrying robot 400b, its carrying end can be rotated so that the second part of the workpiece's surface faces the working mechanism 300, so that the working mechanism 300 processes the second part of the workpiece's surface.

[0139] In this utility model, the working mechanism 300 processes the workpiece, including processing performed by the vision unit 301 and / or the processing unit 302. For example, the vision unit 301 may perform visual positioning processing or visual inspection processing, or the processing unit 302 may perform cleaning processing, or the processing may include processing performed by both the vision unit 301 and the processing unit 302.

[0140] In this invention, the working mechanism 300 for treating the first part of the workpiece surface and the working mechanism 300 for treating the second part of the workpiece surface can be the same working mechanism 300 or different working mechanisms 300.

[0141] In this invention, the first part of the surface and the second part of the surface are different. For example, when the first multi-axis mounting robot 400a is mounted, the working mechanism 300 processes the front side of the workpiece, and when the second multi-axis mounting robot 400b is mounted, the working mechanism 300 processes the back side of the workpiece. This enables the detection and processing of multiple sides of the workpiece within a compact workstation, resulting in higher efficiency.

At this time, the output joints of the two robots can be at the same height (basically at the same height, allowing for a certain measurement error). When the two multi-axis mounting robots 400 transfer workpieces in the horizontal direction of the workstation, both multi-axis robots can be located below the working mechanism 300, or both multi-axis robots can be located above the working mechanism 300, or one multi-axis mounting robot 400 can be located below the other multi-axis mounting robot 400.
