The side of the rotating platform 700 away from the second linear movement module 200 is provided with a jig 201. The jig 201 is used for placing the workpiece to be processed. The vision assembly 300 comprises a camera 301, a storage and a display screen 303. The camera 301 is arranged on the second linear movement module 200 or the base 500. The jig 201 can be moved to a position corresponding to the camera 301. The storage is used for storing images. The display screen 303 is used for displaying image information. The first linear movement module 110 can drive the plurality of pad printing heads 107 to move in the Y-axis direction. The second linear movement module 200 can drive the jig 201 to move in the X-axis direction. The rotating platform 700 can drive the jig 201 to rotate.

[0030] The base 500 provides stable support for the pad printing die set 100, so that the pad printing process is more stable and efficient. The pad printing die set 100 is provided with a first linear movement module, which is used to drive the pad printing head to move in the Y-axis direction, facilitating pad printing processing of the workpiece to be processed. The second linear movement module 200 is provided with a jig 201, and the workpiece to be processed is placed on the jig 201. The second linear movement module 200 can drive the jig 201 to move in the X-axis direction, so that the workpiece to be processed on the jig 201 moves to the pad printing die set 100, facilitating pad printing processing of the pad printing die set 100. The rotating platform 700 can drive the jig 201 to rotate, so as to facilitate the workpiece to be processed to correspond to the pad printing head 107. The camera is mainly used to shoot the image information of the workpiece to be processed on the jig 201, and then compare it with the standard image in the memory. Through the existing comparison model, the X-axis direction displacement, Y-axis direction displacement and rotation angle parameters required for adjustment of the pad printing die set 100 are compared and obtained, and are displayed to the operator through the display screen 303. The operator adjusts the pad printing die set 100 or adjusts the second linear movement module 200 through the specific image information and parameters on the display screen 303, so that the pad printing processing of the pad printing die set 100 on the workpiece to be processed is more accurate and precise. Such a setting mode enables the multi-station pad printing device 1000 with calibration function to quickly and simply provide the currently required adjustment parameters through image information comparison, so that the error between the current workpiece to be processed and the required standard is more intuitive and accurate, and the operator can more conveniently and accurately control the pad printing die set 100 and the second linear movement module 200 for adjustment, so as to realize accurate positioning and fine adjustment of the pad printing process of the multi-station pad printing device 1000 with calibration function, and ensure the accuracy of the pad printing process of the multi-station pad printing device 1000 with calibration function.

[0031] Among them, the camera in the visual assembly 300 can quickly and accurately capture the image of the workpiece to be processed, the memory is used to save the standard image information, and the real-time image data shot by the camera 301, and support for subsequent processing is provided by comparing these image data.

[0032] It should be noted that in this embodiment, the camera 301 and the memory are used to compare the real-time image information, which facilitates the user to adjust and control the multi-station pad printing device 1000 with calibration function. Then, the operator manually controls the adjustment and control of the pad printing die set 100.

[0033] Specifically, the display screen 303 is used to display image information, the camera 301 in the visual assembly 300 is used to shoot and read the image information of the workpiece to be processed, and is compared with the standard information in the memory, so as to subsequent pad printing processing of the workpiece to be processed. Therefore, the display screen 303 can help the user to more conveniently and intuitively observe the image information of the workpiece to be processed, and control and adjust the multi-station pad printing device 1000 with calibration function according to the image information, so as to ensure the smooth progress of the printing process.

[0034] It should be noted that the memory in the embodiment is a programmable logic controller (PLC). The PLC is a digital operation electronic system specially designed for application in industrial environment. It uses a programmable memory to store instructions for performing logic operations, sequential control, timing, counting and arithmetic operations in its internal memory, and controls various types of mechanical equipment or production processes through digital or analog input and output.

[0035] Among them, the rotating platform 700 is arranged between the second linear motion module 200 and the jig 201, and the rotating platform 700 can drive the jig 201 to rotate, further enhancing the movement ability of the jig 201 and the workpiece to be processed. In addition to the linear motion of the jig 201 and the workpiece to be processed arranged on the jig 201 driven by the second linear motion module 200, the workpiece to be processed can also be driven to rotate by the rotating platform 700 to facilitate the processing and observation of the workpiece to be processed. The rotating platform 700 provides an additional rotating function, so that the workpiece to be processed can rotate during processing, improving the flexibility and diversity of the multi-station pad printing device 1000 with calibration function when processing workpieces.

[0036] It is easy to understand that the workpiece to be processed is placed on the rotating platform 700, so that the workpiece to be processed can be processed at different angles by rotating on the rotating platform 700, which is beneficial to realize the multi-angle processing requirement and improve the processing precision and efficiency.

[0037] Reference Figures 1-3 The base 500 is provided with a first sliding rail 501 extending in the vertical direction, and a sliding platform 502 in sliding connection with the first sliding rail 501, and the second linear motion module 200 is arranged on the sliding platform 502.

[0038] The first sliding rail 501 extending in the vertical direction is arranged on the base 500, and the sliding platform 502 in sliding connection with the first sliding rail 501, so that the sliding platform 502 can stably move in the vertical direction, ensuring that the movement process of the sliding platform 502 remains stable.

[0039] It should be noted that in the embodiment, the screw rod 111 and the hand wheel are arranged on the sliding platform 502, the rotating movement of the hand wheel is converted into the linear movement of the sliding platform 502 through the direct connection of the hand wheel and the screw rod 111.

[0040] With reference to Figure 2 , Figure 4 and Figure 5 , the pad printing module 100 further comprises a rack 101 and a plurality of first sliding assemblies 106, the first linear movement module 110 is arranged in the rack 101, the first linear movement module 110 comprises a rotating driving member 113, a screw rod 111 and a moving table 112, the screw rod 111 is in transmission connection with the rotating driving member 113, the screw rod 111 is in threaded connection with the moving table 112, opposite sides of the moving table 112 are respectively provided with lifting modules 104, the bottom of the two lifting modules 104 is connected with a first mounting plate 105, the first sliding assembly 106 is arranged on the side of the first mounting plate 105 away from the lifting module 104, and the pad printing head 107 is connected on each first sliding assembly 106, so that the pad printing head 107 can slide along the extension direction of the first mounting plate 105 or slide along the direction perpendicular to the extension direction of the first mounting plate 105.

[0041] The rack 101 protects and seals the electronic components and mechanical structures in the pad printing module 100 to avoid the influence and interference of the external environment on the electronic components. The first linear movement module 110 is arranged in the rack 101, the screw rod 111 is in transmission connection with the rotating driving member 113, and the screw rod 111 is in threaded connection with the moving table 112, so that when the rotating driving member 113 drives the screw rod 111 to rotate, the moving table 112 can move due to the rotation of the screw rod 111 because the screw rod 111 remains fixed relative to the rack 101, thereby realizing the movement of the moving table 112 and the pad printing head 107 relative to the rack 101 in the Y-axis direction.

[0042] On the other hand, the lifting module 104 is arranged on the opposite sides of the moving table 112, the bottom of the two lifting modules 104 is connected with the first mounting plate 105, and the pad printing head 107 is connected on the first mounting plate 105, so that the pad printing head 107 is driven to move vertically through the driving of the lifting module 104. Through the above structural arrangement, the pad printing head 107 has the movement ability in the vertical direction and the Y-axis direction, the movement range of the pad printing head 107 is improved, and the movement of the pad printing head 107 and the subsequent pad printing processing of the workpiece to be processed are facilitated.

[0043] Among them, the moving table 112 can move linearly through the first linear movement module 110, realizing the accurate movement and control of the pad printing head 107 in the Y-axis direction. The lifting module 104 can accurately control and move the first mounting plate 105 in the vertical direction, thereby ensuring the accuracy of the printing position.

[0044] Specifically, the design of the two lifting modules 104 makes the first mounting plate 105 stable and smooth during vertical movement, improving the stability of the multi-station pad printing device 1000 with calibration function.

[0045] Specifically, the pad printing head 107 is slidably connected to the first mounting plate 105 through the first sliding assembly 106, so that the pad printing head 107 can move smoothly along the extension direction of the first mounting plate 105 or perpendicular to the extension direction of the first mounting plate 105, making the pad printing process more convenient and stable.

[0046] Reference Figure 5 The first mounting plate 105 is provided with a guide column 1051 facing the moving table 112, and the moving table 112 is provided with a linear bearing 1121 corresponding to the guide column 1051, and the guide column 1051 is slidably connected to the moving table 112 through the linear bearing 1121.

[0047] The linear bearing 1121 is installed in the moving table 112, and the guide column 1051 moves relative to the moving table 112 through the sliding connection between the linear bearing 1121. The guide column 1051 can effectively realize the positioning and guiding function of the movement of the first mounting plate 105 relative to the moving table 112 when the first mounting plate 105 is vertically moved by the lifting module 104, ensuring the accuracy of the movement of the first mounting plate 105 relative to the moving table 112, and improving the positioning accuracy and stability of the multi-station pad printing device 1000 with calibration function.

[0048] Specifically, through the sliding connection of the guide column 1051 and the linear bearing 1121, the friction and vibration of the moving table 112 during movement can be reduced, the running stability of the multi-station pad printing device 1000 with calibration function can be improved, and the energy consumption can be reduced.

[0049] It is easy to understand that through the connection of the guide column 1051 and the linear bearing 1121, the deviation and error of the first mounting plate 105 during movement relative to the moving table 112 can be effectively reduced, the reliability and stability of the multi-station pad printing device 1000 with calibration function can be improved, and the long-term stable operation of the multi-station pad printing device 1000 with calibration function can be ensured.

[0050] Reference Figure 6The second slide rail 1052 is arranged on the side of the first mounting plate 105 away from the lifting module 104 and extends along the length direction of the first mounting plate 105. The first slide assembly 106 includes a plurality of first sliding blocks 1061 and second sliding blocks 1062. The first sliding blocks 1061 are in sliding connection with the second slide rail 1052. The side of the first sliding blocks 1061 away from the second slide rail 1052 is provided with a third slide rail 10611. The second sliding blocks 1062 are in sliding connection with the third slide rail 10611. The arrangement direction of the second slide rail 1052 is perpendicular to the arrangement direction of the third slide rail 10611. The end of the second sliding blocks 1062 is connected with the pad printing head 107.

[0051] The first slide assembly 106 can increase the flexibility between the pad printing head 107 and the first mounting plate 105, so that the pad printing head 107 can move relative to the first mounting plate 105 through the first slide assembly 106, and the flexibility and applicability of the pad printing head 107 are higher. In the first slide assembly 106, the arrangement direction of the second slide rail 1052 is perpendicular to the arrangement direction of the third slide rail 10611, so the movement direction of the first sliding blocks 1061 and the second sliding blocks 1062 is perpendicular to each other, so that the pad printing head 107 has a larger movement range, so that the multi-station pad printing device 1000 with the calibration function can more conveniently and quickly complete the pad printing processing of the workpiece to be processed. At the same time, the multi-stage sliding connection mode of the first slide assembly 106 can provide more stable support and smooth movement, which helps to maintain the precision of the multi-station pad printing device 1000 with the printing position fine adjustment and calibration function.

[0052] The arrangement direction of the second slide rail 1052 is perpendicular to the arrangement direction of the third slide rail 10611, so that the pad printing head 107 can move in two perpendicular directions, so that the pad printing head 107 has a larger movement range and can be more flexible to move to the pad printing groove 10811 for ink dipping, and to the workpiece to be processed for pad printing processing. The pad printing head 107 is arranged on the first slide assembly 106, so that the pad printing head 107 can be accurately moved, and the accuracy and stability of the printing position fine adjustment are ensured.

[0053] It should be noted that the first mounting plate 105 and the second slide rail 1052 are integrally formed.

[0054] Reference Figure 4 and Figure 8The pad printing module 100 further comprises a plurality of ink assemblies 108, which are arranged one-to-one with the pad printing heads 107. The ink assembly 108 comprises an ink supply platform 1081, an ink cartridge 1082, and a pushing mechanism 1083. The ink supply platform 1081 is arranged on the rack 101. The ink cartridge 1082 is arranged on the ink supply platform 1081 and is in sliding connection with the ink supply platform 1081. The side of the ink supply platform 1081 away from the ink cartridge 1082 is provided with a pad printing groove 10811. The pushing mechanism 1083 is arranged on the rack 101 and can push the ink cartridge 1082 to move to the pad printing groove 10811.

[0055] The ink cartridge 1082 can flow the ink inside to the pad printing groove 10811 to ensure that the ink in the pad printing groove 10811 is sufficient, and to maintain the stability and uniformity of the ink supply. The pushing mechanism 1083 is arranged corresponding to the ink cartridge 1082. The pushing mechanism 1083 can push the ink cartridge 1082 to move to the pad printing groove 10811, so that the movement control of the ink cartridge 1082 and the supply and control of the ink to the pad printing groove 10811 are more accurate and convenient, and the working efficiency of the ink assembly 108 is improved.

[0056] In actual use, the pad printing head 107 is driven in the horizontal direction by the rotating drive 113 and the lead screw 111, and the lifting module 104 is driven in the vertical direction, so that the pad printing head 107 can move in a larger range, and the pad printing head 107 can conveniently dip the ink from the pad printing groove 10811 to complete the pad printing processing of the workpiece. The movement of the pad printing head 107 in the horizontal direction and the vertical direction enables the pad printing head 107 to complete the processing work of dipping the ink and pad printing the workpiece. The pad printing head 107 has relatively flexible mobility, so that the multi-station pad printing device 1000 with the calibration function can adapt to workpieces of different sizes and dimensions, and the accuracy and flexibility of pad printing processing are improved.

[0057] Specifically, the ink cartridge 1082 is in sliding connection with the ink supply platform 1081 and can be slid to the pad printing groove 10811 by the pushing of the pushing mechanism 1083 to supply ink to the pad printing groove 10811, so as to facilitate subsequent pad printing processing. This design enables the ink cartridge 1082 to be stably and slidably connected with the ink supply platform 1081, and facilitates the connection between the ink cartridge 1082 and the pad printing groove 10811, which helps to ensure the stable supply of ink.

[0058] It should be noted that in the present embodiment, the side of the ink cartridge 1082 facing the ink supply platform 1081 is provided with an ink leakage hole. The ink leakage hole helps to control the flow of ink into the pad printing groove 10811 to ensure that the ink in the pad printing groove 10811 is sufficient, and facilitates subsequent pad printing processing.

[0060] The ink supply platform 1081 is slidably connected with the rack 101 through the second sliding assembly 109, so as to realize the multidirectional movement of the ink supply platform 1081 relative to the rack 101, thereby expanding the flexibility and applicability of the multi-station transfer printing device 1000 with the calibration function in use. The second mounting plate 1091 in the second sliding assembly 109 is provided with the fourth sliding rail 1092, a plurality of third sliding blocks 1093 are slidably connected with the fourth sliding rail 1092, the third sliding block 1093 is further provided with the fifth sliding rail 10931, the fourth sliding block 1094 is slidably connected with the fifth sliding rail 10931, and the ink supply platform 1081 is connected on the side of the fourth sliding block 1094 away from the fifth sliding rail 10931. The setting direction of the fourth sliding rail 1092 is perpendicular to the setting direction of the fifth sliding rail 10931, so that the ink supply platform 1081 can move in two directions, thereby expanding the movement ability of the ink supply platform 1081 and further enhancing the movement ability and applicability of the multi-station transfer printing device 1000 with the calibration function.

[0061] Specifically, the multi-stage sliding connection of the second sliding assembly 109 can enhance the movement ability of the ink supply platform 1081, reduce friction, improve the stability and precision of the sliding of the second sliding assembly 109, and help to ensure the accurate movement of the ink supply platform 1081.

[0062] The setting direction of the fourth sliding rail 1092 is perpendicular to the setting direction of the fifth sliding rail 10931, so that the movement directions of the third sliding block 1093 and the fourth sliding block 1094 are perpendicular to each other, that is, the ink supply platform 1081 can move in two mutually perpendicular horizontal directions, so that the movement ability of the ink supply platform 1081 is better and the movement range is larger.

[0063] It should be noted that the second mounting plate 1091 and the fourth sliding rail 1092 are integrally formed.

[0064] Reference Figure 4 and Figure 8The pushing mechanism 1083 comprises a linear driving element, a pushing rod 10832 and a plurality of limiting clamps 10833 connected with each other. The linear driving element is arranged in the rack 101, the pushing rod 10832 is connected with the linear driving element through the rack 101, one end of the pushing rod 10832 away from the rack 101 is connected with a connecting plate 10844, and the plurality of limiting clamps 10833 are arranged on the side of the connecting plate 10844 away from the pushing rod 10832. The limiting clamps 10833 are used for clamping the ink cartridge 1082.

[0065] The linear driving element in the pushing mechanism 1083 is arranged on one side of the rack 101, and the pushing rod 10832 is connected with the linear driving element through the rack body of the rack 101, so as to realize the driving of the linear driving element on the pushing rod 10832. The limiting clamps 10833 are arranged on the end of the pushing rod 10832 away from the linear driving element, and the limiting clamps 10833 can drive the ink cartridge 1082 to move to the pad printing groove 10811 due to the driving of the pushing rod 10832, so that the ink cartridge 1082 supplies ink to the pad printing groove 10811. The above arrangement can make the ink supply process of the ink cartridge 1082 to the pad printing groove 10811 more convenient and fast, and improve the supply efficiency of the pad printing process. In actual use, the pushing mechanism 1083 drives the ink cartridge 1082 to move, and when the ink cartridge 1082 moves to the pad printing groove 10811, the ink in the ink cartridge 1082 is exposed to the pad printing groove 10811. After the pad printing groove 10811 is filled with ink, the ink cartridge 1082 is driven back to the initial position by the pushing mechanism 1083.

[0066] The end of the pushing rod 10832 away from the rack 101 is connected with a connecting plate 10844. The limiting clamps 10833 and the pushing rod 10832 are connected through the connecting plate 10844, so that the pushing force of the pushing rod 10832 can be transmitted to the connecting plate 10844, and then the connecting plate 10844 uniformly disperses to each limiting clamp 10833, so that the pushing force received by each limiting clamp 10833 is consistent as much as possible, and the movement of the limiting clamp 10833 driving the ink cartridge 1082 is more stable.

[0067] Specifically, the pushing rod 10832 in the pushing mechanism 1083 is connected with the linear driving assembly through the rack 101, and the limiting clamps 10833 on the other end of the driving rod are clamped and connected with the ink cartridge 1082, so that the connection between the pushing mechanism 1083 and the ink cartridge 1082 is stable, and the pushing mechanism 1083 pushes the ink cartridge 1082 on the ink supply platform 1081 more stably, and is not easy to shake or deviate, thereby ensuring the stability and printing quality in the pad printing process.

[0068] It should be noted that in the embodiment, the push rod 10832 is provided with a connecting plate 10844, and the connecting plate 10844 is provided with a plurality of limiting clips 10833, which are arranged one by one with the ink cartridge 1082.

[0069] With reference to Figure 1 and Figure 3 The multi-station pad printing device 1000 with the calibration function further comprises an operation panel 600, which is located on the pad printing module 100.

[0070] Specifically, the operation panel 600 is located on the pad printing module 100, and an operator can conveniently set, adjust and control the multi-station pad printing device 1000 with the calibration function through the operation panel 600, thereby improving the convenience and efficiency of the operation of the multi-station pad printing device 1000 with the calibration function.

[0071] The operation panel 600 can realize the transmission and interaction of information of the multi-station pad printing device 1000 with the calibration function, and an operator can set parameters through the operation panel 600, control the operation of the multi-station pad printing device 1000 with the calibration function, and obtain feedback information through the display screen 303, so that the operation of the multi-station pad printing device 1000 with the calibration function is more intelligent and humanized.

[0072] With reference to Figure 1 and Figure 2 The pad printing module further comprises a cleaning assembly, a fixed plate of the cleaning assembly, and shafts arranged on opposite sides of the fixed plate, the fixed plate is connected with the rack, and the fixed plate is located on a side of the ink supply platform away from the rack, a cleaning belt is sleeved on one of the shafts, the cleaning belt is covered on the surface of the fixed plate, and the other shaft is used for recycling the cleaning belt.

[0073] The design of the cleaning assembly helps to maintain the clean state of the pad printing module. By cleaning the pad printing heads, the influence of pollution and dust on the printing quality of the pad printing heads can be avoided, and good pad printing effect can be ensured every time. In actual use, after each pad printing head moves to the pad printing groove to dip the ink pigment and processes the workpiece, the pad printing head moves to the fixed plate, and the cleaning belt covered on the fixed plate performs a pad printing action to paste the excess pigment on the pad printing head on the cleaning belt. After the excess pigment of the plurality of pad printing heads is cleaned on the cleaning belt, the one-side shaft rotates to recycle the dirty cleaning belt, and the other-side shaft rotates to cover the cleaning belt on the surface of the fixed plate.

[0074] Specifically, by cleaning the pad printing head by smearing the excess ink pigment on the cleaning belt, the possibility of contamination of the workpiece during the pad printing process can be reduced, and the pad printing effect of the multi-station pad printing device with calibration function can be improved.

[0075] The cleaning assembly has a simple structure, so that the cleaning process of the pad printing head is more convenient and efficient. The cleaning action can be performed during the movement of the pad printing head and the pad printing process, which can quickly and effectively clean the pad printing head, reduce the influence and interference on the normal pad printing process, and improve the production efficiency.

[0076] Reference Figure 2 The visual assembly 300 further comprises a light supplement lamp 302 connected with the second linear movement module 200 or the base 500, and the light supplement lamp 302 is located below the camera 301 and is correspondingly arranged with the camera 301.

[0077] The light supplement lamp 302 can provide additional light source for the camera 301, helping the camera 301 to obtain clearer and more uniform brightness images. This helps to improve the image performance of the visual assembly 300 and improve the quality and clarity of the image data. The setting of the light supplement lamp 302 can reduce the influence of uneven illumination and improve the image quality and stability of the camera 301. This helps to improve the detection accuracy of the visual system and reduce the error rate.

[0078] The light supplement effect of the light supplement lamp 302 can reduce shadows and reflections and improve the contrast of the image. This helps the camera 301 to more accurately identify the marks or reference points on the surface of the workpiece, thereby improving the accuracy of image information analysis and comparison.
