Description

Technical Field

[0001] The invention belongs to the technical field of pad printing machines, and in particular relates to a double-module double-pad pad printing machine. Background Art

[0002] Pad printer is a printing device that uses a soft and deformable silicone rubber head to transfer the ink on the printing plate to the surface of the product. As a type of gravure printing, it is widely used in plastics, toys, glass, metals, ceramics, electronics, IC sealing and other fields.

[0003] In the pad printing operation of the mobile phone middle frame, a mobile phone middle frame needs to be pad printed at two positions on one side, and a total of four positions on both sides. However, the current existing technology can only use single-glue pad printing. Single-glue pad printing will cause uneven force on the product, and one side will drop when pressed down, while the other side will not be stressed and will be lifted, resulting in a large pad printing offset problem. The pad printing of the mobile phone middle frame requires pad printing at four positions. The single-glue pad printing technology can only print one point at a time, and one product needs to be pad printed four times. Therefore, the pad printing efficiency is low. To improve the efficiency of the single-glue head technology, it is necessary to increase the workstation, which will also increase the size of the entire machine, and thus the entire machine occupies a large area. Summary of the invention

[0004] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a double-module double-pad pad printer.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A double-module double-pad pad printer, comprising a frame, on which two sets of double-pad mechanisms are installed in parallel, and the double-pad mechanisms include a support, which is in an inverted double T shape, and on which two sets of single-pad mechanisms are installed;

[0007] The single glue head mechanism includes a slide rail installed on the inner side wall of the support and a mounting plate installed on the top of the support, the slide rail is slidably mounted with a slider, the slider is mounted with a moving frame, the moving frame is rectangular, the moving frame passes through the support, a threaded sleeve is mounted at the top center of the moving frame, the mounting plate is mounted with a mounting frame, the mounting frame is mounted with a motor, the output end of the motor is connected with a screw rod, the screw rod is rotatably mounted on the support, and the screw rod thread matches the threaded sleeve;

[0008] An XYR three-axis motion platform is installed at the bottom of the moving frame, a rubber head seat is installed at the output end of the XYR three-axis motion platform, and a rubber head is installed on the rubber head seat.

[0009] It is further defined that a drag chain is installed between the mobile rack and the rack. With this design, the drag chain can wrap the wires, cables and other components of the mechanical equipment to prevent them from being damaged due to external friction, impact or other factors when moving, and the overall appearance is better.

[0010] It is further defined that the support is equipped with a sensor, and the movable frame is equipped with a sensor plate whose position is adapted to the sensor. Such a design can monitor the moving position of the movable frame, and then monitor the moving position of the rubber head at the lower end to prevent overtravel and collision problems.

[0011] It is further defined that a coupling is installed between the motor and the screw rod. Such a design can compensate for axial, radial and angular deviations between the motor and the screw rod, and efficiently transmit motion and torque.

[0012] It is further defined that both side surfaces of the XYR three-axis motion platform are equipped with correctors. With this design, the correctors monitor the moving state of the XYR three-axis motion platform in real time and compare it with the preset position. Once a deviation is found, it is corrected immediately. This precise position adjustment ensures that the XYR three-axis motion platform can move according to the predetermined trajectory and position. The presence of the correctors can significantly improve the positioning accuracy of the XYR three-axis motion platform, thereby meeting the needs of high-precision processing or experiments.

[0013] It is further defined that the frame is composed of square tubes. Such a design is easy to purchase, light and easy to move, easy to weld and splice, and has good load-bearing and supporting effects.

[0014] It is further defined that a limit block is installed inside the mobile frame. With this design, the support cooperates with the limit block to limit the descending position of the mobile frame to prevent the mobile frame from falling when a malfunction occurs, causing a collision accident with the rubber head below.

[0015] It is further defined that a spacer block is installed between the output end of the XYR three-axis motion platform and the rubber head seat. Such a design, to a certain extent, expands the movable distance of the mobile frame and expands the scope of use.

[0016] The beneficial effects of the present invention are as follows:

[0017] The operation mode of the dual-module dual-pad structure in the present invention realizes the simultaneous operation of two groups of dual-pad structures, that is, it can realize the alternating pad printing of two workstations at the same time, thereby improving the pad printing efficiency. Moreover, compared with the structure of a single pad, the structure of the dual-pad can pad print two pad printing positions at the same time, so there is no problem of uneven force on the product when pad printing with a single pad.

[0018] The present invention achieves an effect of four times the efficiency of a single-pad pad printing machine, while the installation space required is much smaller than that of four single-pad pad printing machines, thus saving floor space. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1 to Figure 4 As shown, the double-module double-pad pad printer of the present invention comprises a frame 1, on which two sets of double-pad mechanisms 2 are installed in parallel, and the double-pad mechanisms 2 comprise a support 21, which is in an inverted double T shape, and on which two sets of single-pad mechanisms 3 are installed;

[0030] The single glue head mechanism 3 includes a slide rail 31 installed on the inner side wall of the support 21 and a mounting plate 32 installed on the top of the support 21. The slide rail 31 is slidably mounted with a slider 33, and the slider 33 is mounted with a moving frame 34. The moving frame 34 is rectangular and passes through the support 21. A threaded sleeve 35 is installed at the center of the top of the moving frame 34. The mounting plate 32 is mounted with a mounting frame 36. The mounting frame 36 is mounted with a motor 37. The output end of the motor 37 is connected to a screw rod 38. The screw rod 38 is rotatably mounted on the support 21, and the screw rod 38 is threadedly matched with the threaded sleeve 35.

[0031] An XYR three-axis motion platform 39 is installed at the bottom of the moving frame 34 . A glue head seat 310 is installed at the output end of the XYR three-axis motion platform 39 . A glue head 311 is installed on the glue head seat 310 .

[0032] Preferably, a drag chain 4 is installed between the movable frame 34 and the frame 1. With this design, the drag chain can wrap the wires, cables and other components of the mechanical equipment to prevent them from being damaged by external friction, impact or other factors when moving, and the overall appearance is better. In fact, the way of bundling the wires can also be considered according to the specific situation.

[0033] Preferably, the support 21 is installed with a sensor 5, and the movable frame 34 is installed with a sensing plate 6 which is adapted to the position of the sensor 5. Such a design can monitor the moving position of the movable frame 34, and then monitor the moving position of the rubber head 311 at the lower end to prevent overtravel and collision problems. In fact, measures to monitor the moving position of the movable frame 34 can also be considered according to specific circumstances.

[0034] Preferably, a coupling 7 is installed between the motor 37 and the screw rod 38. Such a design can compensate for the axial, radial and angular deviations between the motor 37 and the screw rod 38, and efficiently transmit motion and torque. In fact, the selection of the coupling 7 can also be considered according to specific circumstances.

[0035] Preferably, the two side surfaces of the XYR three-axis motion platform 39 are installed with a deflection corrector 8. With this design, the deflection corrector 8 monitors the moving state of the XYR three-axis motion platform 39 in real time and compares it with the preset position. Once a deviation is found, it is corrected immediately. This precise position adjustment ensures that the XYR three-axis motion platform 39 can move according to the predetermined trajectory and position. The presence of the deflection corrector 8 can significantly improve the positioning accuracy of the XYR three-axis motion platform 39, thereby meeting the needs of high-precision processing or experiments.

In fact, the structure and material selection of the frame 1 can also be considered according to specific circumstances.

[0037] It is preferred that a limit block 9 is installed inside the mobile frame 34. With this design, the support 21 cooperates with the limit block 9 to limit the descending position of the mobile frame 34 to prevent the mobile frame 34 from falling when a malfunction occurs, causing a collision accident with the rubber head 311 below. In fact, limit protection measures can also be considered according to specific circumstances.

[0038] Preferably, a pad block 10 is installed between the output end of the XYR three-axis motion platform 39 and the rubber head seat 310. Such a design expands the movable distance of the movable frame 34 to a certain extent and expands the scope of use. In fact, the height size of the pad block 10 can also be considered according to specific circumstances.

[0039] In this embodiment, when the double-module double-pad pad printer is used, the motor 37 drives the screw 38 to rotate, and under the effect of the threaded sleeve 35, the slider 33 limited by the slide rail 31 and the moving frame 34 installed on the slider 33 are displaced in the support 21, thereby realizing the displacement of the XYR three-axis motion platform 39 installed at the lower side, and then realizing the up and down movement of the pad 311;

[0040] In actual processing, the pad head 311 moves downward to start taking the pattern ink, then moves upward and rises, the product to be printed moves to the bottom of the pad head 311, the pad head 311 moves downward to start pad printing, after the pad printing is completed, the pad head 311 returns to its original position, the product completed with pad printing leaves the bottom of the pad head 311, and then the pad printing machine is equipped with a cleaning structure to clean the pad head 311, thus completing a pad printing process;

[0041] In this structure, two rubber heads 311 realize simultaneous pad printing, ensuring the pad printing effect and improving the pad printing efficiency. Furthermore, the dual-module structure realizes the purpose of alternating pad printing or synchronous pad printing, and two pad printings can be realized in the same process step, further improving the pad printing efficiency.
