[0030] The pad printing module 400 is used to perform pad printing on the pipe to be processed, which is placed on the jig assembly 300. A pad 403 is connected to the three-dimensional movable module 401. The pad 403 is driven by the three-dimensional movable module 401 to move to the ink device 404 to dip ink, then move to the pipe to be processed for pad printing. The base 100 is provided with a rotating ring 101, on which several jig assemblies 300 are mounted. The jig assembly 300 includes a bracket 301 mounted on the rotating ring 101 and a connecting post 302 rotatably connected to the bracket 301. The connecting post 302 is used to connect the pipe to be processed. A fixed disk 102 is provided at the inner ring of the rotating ring 101, and the rotating ring 101 can rotate relative to the fixed disk 102. A plurality of drive modules 200 are arranged in a ring shape on the outer ring of the fixed disk 102, so the fixture assembly 300 provided on the rotating ring 101 can be driven by the rotating ring 101 to rotate and correspond to the plurality of drive modules 200 provided on the fixed disk 102 in sequence. The connecting plate 204 on the driving module 200 can be moved relative to the base 100 by being driven by the translation driving component 201, and the driving shaft 205 arranged on one side of the connecting plate 204 can be rotated relative to the connecting plate 204 by being driven by the rotation driving component 202. Since the driving shaft 205 can be engaged and connected with the connecting column 302, it is locked with the connecting column 302, and the connecting column 302 and the pipe to be processed set on the connecting column 302 are driven by the rotation driving component 202 to rotate, so as to facilitate the pad printing module 400 arranged in an automated moving device 1000 for multi-angle pad printing on the circumference of a pipe to perform pad printing on the pipe to be processed set on the connecting column 302. At the same time, a plurality of jig assemblies 300 are provided on the rotating ring 101, and a plurality of connecting columns 302 are provided on the bracket 301. A pipe to be processed can be provided on each connecting column 302, so the automated mobile device 1000 for multi-angle pad printing on the circumference of the pipe can perform pad printing on a plurality of pipes to be processed at the same time, and can perform multi-angle pad printing on the circumference of the same pipe to be processed, so that the pad printing process of the pipe to be processed is greatly facilitated, the efficiency of the multi-angle pad printing process of the pipe to be processed is improved, and the production and processing costs are reduced.

[0031] Specifically, in the pad printing module 400, the pad head 403 is positioned on the side of the three-dimensional movable module 401 facing the ink device 404. This allows the pad head 403 to have a greater range of movement and flexibility, allowing it to better adapt to the different sizes and shapes of pipes to be processed. This makes the automated mobile device 1000 for multi-angle pad printing around pipes more flexible and suitable for pad printing needs of various specifications and sizes of pipes to be processed. In addition, the positioning of the pipes to be processed by the jig assembly 300 and the actual operation of pad printing can be completed automatically by the device, reducing the need for manual operation, improving production efficiency, and reducing the possibility of human error.

[0032] It should be noted that in this embodiment, a rotary drive member is provided on the base 100, and a turntable is provided on the rotary drive member. A fixed plate 102 is provided on the turntable. The fixed plate 102 partially shields the turntable to form the rotating ring 101 in this embodiment. To enable the turntable to rotate relative to the fixed plate 102, a groove can be provided on the turntable, with a thrust ball bearing disposed within the groove. The bottom of the fixed plate 102 is fixedly connected to the shaft raceway at the bottom of the thrust ball bearing, and the turntable is fixedly connected to the shaft raceway at the top of the bearing. This enables relative rotation of the turntable relative to the fixed plate 102. Alternatively, the rotary drive member's rotating shaft can pass directly through the turntable, and a bearing can be provided on the rotating shaft passing through one side of the turntable. The rotating shaft is fixed to the inner ring of the bearing, and the fixed plate 102 is fixed to the outer ring of the bearing. This can also achieve stationary movement of the fixed plate 102 relative to the base 100. Or a swivel 101 is directly set on the base 100, and a driving member is set at the center of the swivel 101. The driving member is connected to the swivel 101 through an extension rod to drive the swivel 101 to rotate, and a fixed disk 102 is set on the driving member to realize the rotation of the swivel 101 relative to the fixed disk 102.

[0033] It should be noted that in this embodiment, four rotation holes 3011 are provided on the bracket 301, so four connecting posts 302 are provided for rotational connection with the bracket 301. Accordingly, each drive module 200 is provided with four drive shafts 205 correspondingly connected to the connecting posts 302. Furthermore, 12 jig assemblies 300 are provided on the swivel 101, and five drive modules 200 are provided on the base 100 for driving each of the jig assemblies 300. Four pad printing modules 400 are also provided on the base 100. Therefore, in actual use, the pipe to be processed must first be mounted on the connecting posts 302. The jig assemblies 300 are then driven to rotate relative to the drive modules 200 via the swivel 101. The drive shafts 205 of the drive modules 200 are then connected to the connecting posts 302, driving the pipe to be processed to rotate. The pad printing module 400, located on the base 100, then performs pad printing on the pipe to be processed using the three-dimensional moving module 401 and the pad 403. Then, the rotating ring 101 drives the jig assembly 300 to move to the next driving module 200 and the pad printing module 400 for the next pad printing process.

[0034] refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 The translation drive assembly 201 includes a base plate 2012, a connecting block 2013, a first linear drive member 2011 and a slide rail 2014. The base plate 2012 is fixed to the fixed disk 102. The first linear drive member 2011 is fixed to the base plate 2012. The cantilever end of the first linear drive member 2011 is connected to the connecting plate 204. The slide rail 2014 is provided on the base plate 2012. The connecting block 2013 is slidably connected to the base plate 2012 through the slide rail 2014. The connecting block 2013 is connected to the connecting plate 204 is connected, the rotation drive assembly 202 includes a second linear drive member 2021, a mounting plate 2023, a rack 2024 and a plurality of gears 2022, the second linear drive member 2021 is installed on the connecting plate 204 through the mounting plate 2023, the gears 2022 are connected to the drive shaft 205 in a one-to-one correspondence, the second linear drive member 2021 is connected to the rack 2024, the rack 2024 is slidably connected to the connecting plate 204, and the rack 2024 is meshedly connected to the plurality of gears 2022.

[0035] On the one hand, the translation drive assembly 201 includes a base plate 2012, a connecting block 2013, a first linear drive member 20111 and a slide rail 2014. The base plate 2012 is fixedly connected to the base. The first linear drive member 20111 in the linear drive assembly 201 is arranged on the base plate 2012. The cantilever end of the first linear drive member 20111 is connected to the connecting plate 204, and the connecting plate 204 is connected to the base plate 2012 through the sliding connection between the connecting block 2013 and the slide rail 2014. Therefore, the first linear drive member 2011 can drive the connecting plate 204 and the drive shaft 205 set on the connecting plate 204 to move relative to the base 100, ensuring that the drive shaft 205 can move to the connecting column 302 to achieve the snap fit between the drive shaft and the connecting column 302.

[0036] On the other hand, the rotary drive assembly 202 includes a gear 2022, a second linear drive member 2021, and a mounting plate 2023. The second linear drive member 2021 is mounted on the side of the connecting plate 204 away from the drive shaft 205 via the mounting plate 2023, and the gear 2022 is arranged corresponding to the drive shaft 205 and is arranged on the other side of the connecting plate 204. Therefore, the second linear drive member 202 is connected to the rack 2024, and the rack 2024 is slidably connected to the connecting plate 204, so that the rack 2024 can move relative to the connecting plate 204 under the drive of the second linear drive member 202; at the same time, the rack 2024 is engaged with a plurality of gears 2022, so that the second linear drive member 202 can synchronously drive multiple gears 2022 to rotate at the same time, thereby realizing the driving gear 2022 to drive the driving shaft 205 to rotate relative to the connecting plate 204, so that the driving shaft 205 can correspond to the connecting column 302 in the setting direction, and after the driving shaft 205 is engaged and connected with the connecting column 302, the driving shaft 205 can drive the connecting column 302 to rotate, thereby facilitating the pad printing module 400 to pad print the pipe to be processed on the connecting column 302.

[0037] Specifically, a bracket 301 is provided on the base 100, and a rotation 3011 is provided on the bracket 301. The connecting column is rotatably connected to the bracket 301 through the rotating hole 3011, and the connecting column 302 is engaged with the drive shaft 205. The above arrangement can ensure that the pipe to be processed maintains precise positioning and angle with the jig assembly 300 during the pad printing process, thereby ensuring the accuracy and consistency of the pad printing processing of multiple pipes to be processed by the pad printing module 400, and the pad printing processing of the same pipe to be processed by multiple pad printing modules 400.

[0038] Specifically, the first linear drive 2011 drives the connecting plate 204 and the drive shaft 205 to move relative to the base plate 2012, and the second linear drive 202 drives the rack 2024 to move linearly relative to the connecting plate 204. The teeth on the rack 2024 mesh with the teeth of the gear 2022, converting the linear motion of the rack 2024 into rotational motion of the gear 2022, thereby driving the drive shaft 205 to rotate relative to the connecting plate 204, thereby achieving rotational control of the processing pipe to ensure printing quality and accuracy. The engagement of the drive rail 203 with the connecting column 302 can effectively prevent the processing pipe from deflecting or shaking during the pad printing process, ensuring the stability and accuracy of the processing pipe during the pad printing process.

[0039] refer to Figure 3 and Figure 4 The connecting column 302 includes a holding portion 3021, a rotating portion 3022 and a connecting portion 3023 connected in sequence. The rotating portion 3022 is rotatably connected to the bracket 301. The rotating portion 3022 is provided with a limit block 3024 for limiting the bracket 301. The holding portion 3021 is provided with a clamping groove 30211. The driving shaft 205 is provided with a clamping protrusion 203 corresponding to the clamping groove 30211. The connecting portion 3023 is used to connect the pipe to be processed.

[0040] During actual use, the pipe to be processed is first set on the connecting column 302, and the jig assembly 300 can be rotated relative to the base 100 via the swivel 101, so that the jig assembly 300 set on the swivel 101 rotates to correspond to the drive module 200 set on the base 100. The drive shaft 205 on the drive module 200 is first controlled to rotate by the rotary drive assembly 202 so that the direction and angle of the drive shaft 205 correspond to the engaging groove 30221. Then, the linear drive assembly 201 drives the drive shaft 205 and the connecting plate 204 to move relative to the base 100 so that the drive shaft 205 engages with the engaging groove 30211. Thereafter, the drive shaft 205 is again driven to rotate by the rotary drive assembly 202, thereby driving the connecting column 302 and the pipe to be processed set on the connecting column 302 to rotate relative to the base 100. Afterwards, the swivel 101 rotates, driving the jig assembly 300 and the pipe to be processed mounted on the jig assembly 300 to move to the next pad printing module 400 for the next pad printing process. Therefore, with this arrangement, the swivel 101 can be used to drive the jig assembly 300 and the pipe to be processed to different pad printing modules 400, allowing pad printing to be performed on the pipe at multiple angles around the pipe.

[0041] The connecting column 302 includes a retaining portion 3021, a rotating portion 3022, and a connecting portion 3023, which are sequentially connected. The rotating portion 3022 is configured to be rotatably connected to the rotating hole 3011. A locking groove 30211 is provided on the side of the retaining portion 3021 facing the drive module 200 and engages with the retaining protrusion 203 provided on the drive shaft 205. The connecting portion 3023 is configured to connect to the pipe to be processed. A stopper 3024 is provided on the rotating portion 3022. The stopper 3024 cooperates with the retaining portion 3021 to retain the support 301, preventing displacement and shaking of the connecting column 302 relative to the support 301. Furthermore, the stopper 3024 serves to limit and position the pipe to be processed on the connecting portion 3023, preventing displacement and shaking of the pipe during the pad printing process. The above arrangement can ensure that the connecting column 302 maintains precise positioning and angle with the pipe to be processed and the driving module 200 during the pad printing process, thereby ensuring the accuracy and consistency of the pad printing process.

[0042] Specifically, the end of the drive shaft 205 is provided with a latching protrusion 203, and the latching portion 3021 is provided with a latching groove 30211 that engages with the latching protrusion 203, thereby enhancing the motion control and connection stability of the drive module 200 over the connecting column 302 and the pipe to be processed on the connecting column 302. In this embodiment, the latching portion 3021, the rotating portion 3022, and the connecting portion 3023 included in the connecting column 302 can be manufactured by integral molding or connected by a detachable connection. Therefore, in actual use, different sizes and models of connecting portions 3023 can be replaced to correspond to pipes to be processed of different sizes and models. This makes the automated mobile device 1000 for multi-angle pad printing on the circumference of pipes more flexible and applicable to a wider range of applications, and can meet the pad printing needs of different pipes to be processed.

[0043] refer to Figure 6 and Figure 7 The ink device 404 includes an ink cartridge 4041, a pushing mechanism 4042 and a platform 4043 arranged at the bottom of the three-dimensional movable module 401. The pushing mechanism 4042 is arranged on the three-dimensional movable module 401 and corresponds to the ink cartridge 4041. The ink cartridge 4041 is filled with ink, and the ink cartridge 4041 is provided with an ink leakage hole on the side facing the platform 4043. The platform 4043 is provided with a pad printing groove 40431. The pushing mechanism 4042 can push the ink cartridge 4041 to move to the pad printing groove 40431. The pad printing module 400 also includes a lifting mechanism 402. The rubber head 403 is connected to the three-dimensional movable module 401 through the lifting mechanism 402.

[0044] Ink cartridge 4041 is provided with an ink leakage hole on the side facing platform 4043. This hole helps control the flow of ink into pad printing tank 40431, ensuring sufficient ink within pad printing tank 40431 and maintaining a stable and uniform ink supply. A pushing mechanism 4042 is provided corresponding to ink cartridge 4041 and is capable of pushing ink cartridge 4041 to pad printing tank 40431. This makes the movement and control of ink cartridge 4041, as well as the supply and control of ink into pad printing tank 40431, more precise and convenient, thereby improving the operating efficiency of ink device 404.

[0045] Specifically, the rubber head 403 is connected to the three-dimensional movable module 401 through the lifting mechanism 402, which further expands the moving range of the rubber head 403, allowing the rubber head 403 to move in a larger range, so that the rubber head 403 can easily dip ink from the pad printing groove 40431 to complete the pad printing processing of the pipe to be processed.

[0046] Specifically, the lifting mechanism 402 enables the vertical raising and lowering of the pad 403 to facilitate ink application and pad printing of the pipe to be processed. The flexible mobility of the pad 403 allows it to adapt to pipes of varying sizes and dimensions, enhancing the flexibility and adaptability of pad printing. The large range of motion and high flexibility of the pad printing module 400 facilitate pad printing operations, making it easier for operators to complete pad printing operations and improving the production efficiency of the automated mobile device 1000 for multi-angle pad printing of pipe circumferences.

[0047] refer to Figure 6 and Figure 7 The pushing mechanism 4042 includes a third linear driving member 40423, a pushing rod 40421 and a limiting clamp 40422 which are interconnected. The third linear driving member 40423 is arranged on one side of the three-dimensional movable module 401. The pushing rod 40421 passes through the three-dimensional movable module 401 and is connected to the third linear driving member 40423. The limiting clamp 40422 is arranged at one end of the driving rod away from the third linear driving member 40423. The limiting clamp 40422 clamps the ink cartridge 4041.

[0048] The third linear drive member 40423 in the push mechanism 4042 is positioned on one side of the three-dimensional movable module 401. The push rod 40421 passes through the frame of the three-dimensional movable module 401401 and connects to the third linear drive member 40423, enabling the third linear drive member 40423 to drive the push rod 40421. A limit clamp 40422 is positioned at the end of the push rod 40421 facing away from the third linear drive member 40423. Driven by the push rod 40421, the limit clamp 40422 can move the ink cartridge 4041 to the pad printing tank 40431, allowing the ink cartridge 4041 to supply ink to the pad printing tank 40431 through the ink leakage hole. This arrangement facilitates and accelerates the ink supply process from the ink cartridge 4041 to the pad printing tank 40431, thereby improving the ink supply efficiency of the pad printing process. During actual use, the pushing mechanism 4042 drives the ink cartridge 4041 to move. When the ink cartridge 4041 moves to the pad printing groove 40431, the ink in the ink cartridge 4041 is exposed to the pad printing groove 40431 through the ink leakage hole. After the pad printing groove 40431 is filled with ink, the ink cartridge 4041 is brought back to its original position by the pushing mechanism 4042.

[0049] Specifically, the pushing rod 40421 in the pushing mechanism 4042 passes through the three-dimensional movable module 401 and is connected to the linear drive component 40423, and the limiting clamp 40422 at the other end of the driving rod 40421 is clamped and connected to the ink cartridge 4041 to stabilize the connection between the pushing mechanism 4042 and the ink cartridge 4041, so that the pushing mechanism 4042 pushes the ink cartridge 4041 on the platform 4043 more stably and is less likely to shake or deflect, thereby ensuring stability and printing quality during the pad printing process.

[0050] refer to Figure 1 、 Figure 2 and Figure 8 The automated mobile device 1000 for multi-angle pad printing on the circumference of a pipe fitting also includes a loading mechanism 500. The loading mechanism 500 includes a first conveyor belt 501, a second conveyor belt 502, a storage bin 504 and a grabbing module 503 arranged on the base 100. One end of the first conveyor belt 501 is against the second conveyor belt 502, and the other end is connected to the storage bin 504. The storage bin 504 is used to store pipe fittings to be processed. The grabbing module 503 is arranged adjacent to the second conveyor belt 502. The grabbing module 503 can grab the pipe fittings to be processed on the second conveyor belt 502 and install the pipe fittings to be processed on the connecting column 302.

[0051] The loading mechanism 500 can realize an automated loading process, which facilitates the pad printing processing of the pipe to be processed by the automated mobile device 1000 for multi-angle pad printing around the pipe, saves time in the entire processing process, and improves the efficiency of pad printing. The first conveyor belt 501 and the second conveyor belt 502 are arranged on the base 100, and the two are offset, so that the workpiece can be moved from the first conveyor belt 501 to the second conveyor belt 502, so that the pipe to be processed can be moved smoothly and quickly to the grabbing module 503, which facilitates the grabbing module 503 to install the pipe to be processed on the connecting column 302. The grabbing module 503 can grab the pipe to be processed transported on the second conveyor belt 502 and install the pipe to be processed on the connecting column 302, which is convenient for subsequent pad printing processing. The above-mentioned setting method saves the time required for the loading process and improves the efficiency of pad printing processing of the pipe to be processed.

[0052] Specifically, the first conveyor belt 501, the second conveyor belt 502, and the storage bin 504 enable automated loading and transport of pipes to be processed, improving loading speed. The grabbing module 503 can attach pipes to be processed, transported on the second conveyor belt 502, to the connecting column 302, improving loading accuracy. This configuration of the loading mechanism 500 reduces the need for manual operation and improves the production efficiency of pad printing.

[0053] Specifically, the loading mechanism 500 is compact and occupies little space. One end of the first conveyor belt 501 abuts against the second conveyor belt 502, and the other end is connected to the storage bin 504. The grabbing module 503 is adjacent to the second conveyor belt 502, which is suitable for operation in a limited space.

[0054] In this embodiment, the direction of movement of the first conveyor belt 501 for moving the pipes to be processed is perpendicular to the direction of movement of the second conveyor belt 502 for moving the pipes to be processed. This arrangement reduces the space occupied by the loading mechanism 500, making the automated mobile device 1000 for multi-angle pad printing around pipes more compact. Furthermore, this design allows the first and second conveyor belts 501, 502 to move in independent directions, allowing for independent control of each other, thus achieving flexibility and precision in the transportation and loading of the pipes to be processed.

[0055] refer to Figure 1 、 Figure 2 and Figure 8 The grabbing module 503 includes a first linear motion module 5031, a connecting seat 5032 and a plurality of rotating motors 5033 which are interconnected. The connecting seat 5032 is connected to the first linear motion module 5031. The plurality of rotating motors 5033 are respectively arranged on one side of the connecting seat 5032 away from the first linear motion module 5031. A first manipulator 5034 is provided at the end of the rotating motor 5033.

[0056] The first linear motion module 5031 controls multiple rotary motors 5033 and the first manipulator 5034 mounted on the rotary motors 5033 to move relative to the base 100. This expands the range of motion of the gripping module 503, facilitating the first manipulator 5034's proximity to the second conveyor belt 502 to grasp the pipes to be processed and their placement near the jig assembly 300. The rotary motors 5033 control the first manipulator 5034 to grasp the pipes to be processed, adjust them to a uniform orientation and position, and then install them on the connecting column 302, ensuring uniformity and consistency during subsequent multi-angle pad printing.

[0057] Specifically, the first manipulator 5034 is used to grip the pipe to be processed. The rotary motor 5033 can control the rotation of the first manipulator 5034 to achieve precise gripping and release of the pipe to be processed, ensuring accurate and stable gripping. Through the cooperation of the rotary motor 5033 and the first manipulator 5034, the gripping module 503 can achieve fast and precise gripping, improving the efficiency and stability of the gripping operation, which is conducive to improving the overall production efficiency of the automated mobile device 1000 for multi-angle pad printing on the circumference of pipes.

[0059] The second linear motion module 602 is used to control the movement of the second manipulator 603 so that the second manipulator 603 can approach the swivel 101 and the third conveyor belt 601. The second manipulator 603 is used to remove the pipe to be processed from the connecting column 302 after the pad printing process is completed, and move the pipe to be processed to the third conveyor belt 601 for unloading. Among them, the second manipulator 603 is connected to the second linear motion module 602, so that the second manipulator 603 can have a larger range of movement, and can more conveniently perform the grasping and unloading work. The coordinated movement of the second manipulator 603 and the third conveyor belt 601 ensures the accuracy and stability of the unloading action. The third conveyor belt 601 is used to move the pipe to be processed out of the automated mobile device 1000 for multi-angle pad printing on the circumference of the pipe. The above-mentioned setting method improves the degree of automation of the automated mobile device 1000 for multi-angle pad printing on the circumference of the pipe, and can realize automatic unloading of the pipe to be processed after pad printing, thereby improving production efficiency and reducing the need for manual operation.

[0060] Specifically, the second linear motion module 602 is arranged between the third conveyor belt 601 and the rotating ring 101, which can facilitate the second robot 603 to clamp the pipe to be processed that has completed the pad printing process on the jig assembly 300, and can move to the third conveyor belt 601 to complete the unloading work, thereby improving the overall processing efficiency of the automated mobile device 1000 for multi-angle pad printing on the circumference of the pipe.

[0061] It should be noted that, in this embodiment, the third conveyor belt 601 is provided with support feet and is connected to the ground through the support feet, but part of the third conveyor belt 601 is provided on the base 100 to facilitate the cooperation between the second robot 603 and the third conveyor belt 601 in unloading.

The curing module 700 is disposed on the third conveyor belt 601 . The curing module 700 is used to cure the ink on the pipe to be processed.

[0063] Curing module 700 is used to cure the pipes after pad printing. This ensures that the ink on the pipes is solidified and dried, preventing issues such as ink scratching and smudging. This ensures the yield and completeness of the multi-angle pad printing process around the pipes, improving production efficiency and reducing production costs. Curing module 700 is located on third conveyor belt 601 and automatically performs the curing process during the unloading process after pad printing. This enables automatic curing of the pipes, reduces manual intervention, and improves production efficiency.

[0064] Specifically, the curing module 700, positioned on the third conveyor belt 601, automates the curing process while the pipes are being unloaded, saving time and improving production efficiency. Curing is performed immediately after pad printing, eliminating waiting time and shortening the production cycle. Furthermore, placing the curing module 700 on the third conveyor belt 601 makes the entire production process more compact and efficient, reducing space waste.

[0065] It should be noted that, in this embodiment, the curing module 700 can be a curing process using LED irradiation curing or a heating curing process.

The camera 800 is used to monitor the angle and position of the pipe to be processed on the second conveyor belt 502.

[0067] Camera 800 is used to detect whether there are any pipes being processed on the first and second conveyor belts 501, 502. It can also determine the placement angle of the pipes to be processed, helping the gripping module 503 in the loading mechanism 500 adjust the angle of the pipes to be processed so that they can be installed on the jig assembly 300 at a uniform angle. Camera 800 is installed on the base 100 and corresponds to the second conveyor belt 502. The automated mobile device 1000, which facilitates multi-angle pad printing around the pipes, can observe the position and status of the pipes to be processed through camera 800, enabling real-time monitoring of the pipes to be processed. The camera 800 can also identify information such as the position and angle of the pipes to be processed, providing an accurate reference for subsequent pad printing operations.

[0068] Specifically, camera 800 helps the system accurately locate the pipe to be processed.
