Description

Technical Field

[0001] This utility model relates to an automatic loading and unloading mechanical device for pad printing machines. Background Technology

[0002] Pad printing is a printing method that can print text, graphics, and images on the surface of irregularly shaped objects, and it is now becoming an important specialty printing method. For example, the text and patterns on the surface of toy parts are printed using this method, achieving a one-time printing process.

[0003] To achieve fully automated pad printing operations and reduce the labor intensity of pad printing operators, many pad printing machines are equipped with corresponding loading and unloading robots. For example, utility model application number 201921510781.3 discloses a pad printing device using an automatic turntable, which describes a robot arm comprising: a material picking head, a material picking head lifting mechanism, and a material picking head traversing mechanism. The material picking head is mounted on the material picking head lifting mechanism, and the material picking head lifting mechanism is mounted on the material picking head traversing mechanism. The material picking head is described as a suction cup. However, in actual toy pad printing processes, a single robot arm as a loading and unloading device suffers from slow loading and unloading speeds. Even if automated loading and unloading can be achieved, the low efficiency fails to improve the printing production efficiency of the pad printing machine. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic loading and unloading mechanical device for pad printing machines.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An automatic loading and unloading mechanism for a pad printing machine includes a frame, a pad printing turntable mounted on the frame, a loading conveyor frame located inside the frame, a unloading conveyor frame located outside the frame and aligned with the loading conveyor frame, and a dual-arm loading and unloading mechanism fixedly mounted on the frame and spanning the pad printing turntable. The dual-arm loading and unloading mechanism includes two parallel support columns of the same height, a horizontal plate fixed to the two support columns by bolts, two guide columns fixedly mounted to the horizontal plate by an auxiliary plate, a slide plate located on one side of the horizontal plate and assembled with the guide columns, a transverse cylinder mounted at one end of the horizontal plate and assembled with the slide plate, and a loading robot and an unloading robot mounted on the slide plate with identical structures.

[0007] Preferably, the two ends of the slide are fixed with mounting plates by bolts; the upper and lower ends of the mounting plates are provided with round holes for mounting guide columns, and the mounting plates are also provided with mounting holes between the two round holes for docking with the output end of the transverse cylinder.

[0008] Preferably, support plates are welded to both sides above the slide, and the loading and unloading robots are fixedly installed through the support plates.

[0009] Preferably, an L-shaped bracket is welded to the cylinder body of the transverse cylinder near the output end.

[0010] Preferably, the loading robot includes a lifting cylinder fixedly installed with the slide plate, an L-shaped plate located below the lifting cylinder and fixedly installed with the output end of the lifting cylinder, and a material-picking suction cup fixedly installed at the lower end of the L-shaped plate by screws.

[0011] Preferably, the height of the loading conveyor is lower than the height of the unloading conveyor.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The design of the dual robotic arm loading and unloading mechanism enables automatic loading and unloading of items, reducing the need for manual operation and improving production efficiency. In addition, the cooperation between the loading and unloading robotic arms makes the whole process smoother, reducing the time for handling items and the need for manual intervention.

[0014] 2. Driven by the transverse cylinder, the slide can move smoothly laterally, ensuring the accuracy and speed of loading and unloading, improving the working efficiency of the production line. In addition, the automatic loading and unloading design reduces the waiting time for material handling, making the entire production process more compact and improving the overall production capacity of the machine.

[0015] 3. The loading robot precisely controls the picking and pressing position of the items through the lifting cylinder. The unloading robot can quickly and accurately move the printed items to the unloading conveyor, ensuring that the items are not damaged and can remain consistent. The design of the guide column and the slide ensures the stability of the robot, making the handling of items more precise. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0021] Example

[0022] like Figure 1-4 As shown, an automatic loading and unloading mechanical device for a pad printing machine includes a frame 1, a pad printing turntable 2 mounted on the frame 1, a loading conveyor 3 located inside the frame 1, a unloading conveyor 4 located outside the frame 1 and on the same straight line as the loading conveyor 3, and a double robotic arm loading and unloading mechanism 5 fixedly mounted on the frame 1 and spanning the pad printing turntable 2.

[0023] The dual-arm loading and unloading mechanism 5 includes two parallel support columns 51 of the same height, a horizontal plate 52 fixed to the two support columns 51 by bolts, two guide columns 53 fixedly installed to the horizontal plate 52 by an auxiliary plate, a slide plate 54 located on one side of the horizontal plate 52 and assembled with the guide columns, a transverse cylinder 55 installed at one end of the horizontal plate 52 and assembled with the slide plate 54, and a loading robot 56 and an unloading robot 57 with the same structure installed on the slide plate 54.

[0024] The two ends of the slide 54 are fixed with mounting plates 541 by bolts. The upper and lower ends of the mounting plates 541 have circular holes 542 for mounting guide pillars 53. The mounting plates 541 also have mounting holes 543 between the two circular holes 542 for connecting with the output end of the transverse cylinder 55. Specifically, the two guide pillars 53 pass through the circular holes 542 in the mounting plates 541, supporting the slide 54. Furthermore, the output end of the transverse cylinder 55 passes through the mounting hole 543 and is fixed with a nut. During operation, the transverse cylinder 55 can smoothly transverse the slide 24, allowing the material handling robot 56 and the unloading robot 57 to cooperate in completing the loading and unloading operations.

[0025] Support plates 544 are welded to both sides above the slide plate 54, and the loading robot 56 and unloading robot 57 are fixedly installed through the support plates 544.

[0026] An L-shaped bracket 551 is welded to the cylinder body of the transverse cylinder 55 near the output end. Specifically, the L-shaped bracket 551 abuts against the auxiliary plate of the support guide column 53 and is fixed with screws, which can make the transverse cylinder 55 installed stably.

[0027] The loading robot 56 includes a lifting cylinder 561 fixedly mounted to a slide plate 54, an L-shaped plate 562 located below the lifting cylinder 561 and fixedly mounted to the output end of the lifting cylinder 561, and a material-grabbing suction cup 263 fixedly mounted to the lower end of the L-shaped plate 562 by screws. Specifically, the cylinder body of the lifting cylinder 561 abuts against the support plate 544 and is fixedly mounted to the L-shaped plate 562 after passing through the support plate 544.

[0028] It should be further explained that the slide plate 54 in the dual robotic arm loading and unloading mechanism 5 is driven by the transverse cylinder 55 to move laterally back and forth. During the transverse movement, the unloading robot 57 picks up the printed toys from the mold of the pad printing turntable 2 and then transfers them to the unloading conveyor 4. The toys are then output through the unloading conveyor 4 to complete the automatic unloading. At the same time, the loading robot 56 picks up the unprinted toys from the loading conveyor 3, moves them above the pad printing turntable 2, and then presses them down to press them onto the mold of the pad printing turntable 2 to complete the automatic loading.

[0029] It should be further explained that the height of the loading conveyor 3 is lower than the height of the unloading conveyor 4. Specifically, the loading conveyor 3 needs to pass under the frame 1 to transport unprinted toys. Therefore, the height of the loading conveyor 3 is lower than the height of the unloading conveyor 4. The lifting cylinder of the loading robot 56 needs to make full use of the cylinder stroke to pick up the toys. The unloading conveyor 4 is located outside the frame 1. Therefore, the height of the unloading conveyor 4 can be the same as the pad printing turntable 2, which makes it convenient for the unloading robot 57 to flexibly and quickly pick up and unload the materials.

[0030] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
