Description

Technical Field

[0001] This utility model relates to the field of pad printing machine technology, and in particular to a flexible intelligent loading and unloading device for pad printing machines. Background Technology

[0002] Pad printing machines are a type of special printing equipment based on the principle of "pattern transfer". The core of the machine is to use a silicone printing head to accurately transfer the ink pattern on a steel plate (or offset plate) to the surface of the workpiece. It is especially suitable for irregular, curved, small-area or irregularly shaped workpieces, so as to achieve efficient printing of fine patterns (such as text, logos, QR codes). Therefore, in high-efficiency mass production, it is often used in conjunction with loading and unloading robotic arms to improve pad printing efficiency.

[0003] However, existing robotic arms use suction cups or grippers to grab workpieces and then remove them from the pad printing area. For irregularly shaped parts, grippers are required, which necessitates replacing the suction cups and installing grippers. This causes the pad printing machine to pause for extended periods, reducing pad printing efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 5 As shown, this application provides a flexible intelligent loading and unloading device for a pad printing machine, including: a loading and unloading structure 3, which is used to clamp the workpiece 8 that has been printed on one side of the pad printing machine 7. The loading and unloading structure 3 is set on one side of the pad printing machine 7. The loading and unloading structure 3 includes a support platform 504. A first pulley 501 and a second pulley 502 are symmetrically rotated on one side of the support platform 504. A motor 5 is set on one side of the support platform 504. The driving end of the motor 5 is fixedly connected to the first pulley 501. The motor 5 is fixedly set on one side of the support platform 504 through a fixed frame 505. The first pulley 501 and the second pulley 502 are connected by a transmission belt 503. The upper surface of the transmission belt 503 is connected to the clamping assembly 4. A suction frame 6 is slidably set on one side of the support platform 504. The suction frame 6 is connected to the lower surface of the transmission belt 503.

[0028] After adopting the above technical solution, when it is necessary to replace the clamping component 4 for clamping or the suction cup 601 for picking up, the motor 5 can be started. The motor 5 drives the first pulley 501 to rotate, and the first pulley 501 can drive the second pulley 502 to rotate together through the transmission belt 503. While the transmission belt 503 is circulating, the suction carrier 6 connected to the lower surface will move to one side of the support table 504, while the clamping component 4 connected to the upper surface of the transmission belt 503 will move to the other side, moving towards the suction carrier 6, thereby achieving the effect of alternating replacement and realizing the effect of quickly changing the loading and unloading method, thereby improving the pad printing efficiency.

[0029] Specifically, the clamping assembly 4 includes a push-pull frame 401. A first connecting arm 402 and a second connecting arm 403 are symmetrically and rotatably arranged on one side of the push-pull frame 401. A clamping plate 404 is rotatably arranged at the other end of the first connecting arm 402 and the second connecting arm 403. A protective clamping pad 405 is fixedly arranged on the side of the clamping plate 404 that is close to each other. A carrier slide plate 407 is slidably arranged at the bottom end of the push-pull frame 401 and the clamping plate 404. The carrier slide plate 407 is slidably arranged at the top end of the support platform 504. One side of the support platform 504 is fixedly connected to the upper surface of the second connecting arm 403 through a connecting bracket 408. An electric telescopic rod 409 is fixedly arranged on the other side of the push-pull frame 401. The electric telescopic rod 409 is fixedly arranged on the top side of the carrier slide plate 407. A control plate spring 406 is fixedly arranged on the side of the clamping plate 404 that is close to each other. The protective clamping pad 405 is made of rubber material. The carrier slide plate 407 is T-shaped.

[0030] In an optional implementation, for irregularly shaped parts that cannot be picked up, the clamping assembly 4 can be used for clamping. By extending the electric telescopic rod 409, the push-pull connecting frame 401 can slide on the top of the slide plate 407, thereby gradually increasing the included angle between the first connecting arm 402 and the second connecting arm 403. The control plate spring 406 will also extend, and the clamping plates 404 will move away from each other, thus allowing the workpiece 8 to be released. Conversely, when the push-pull connecting frame 401 is pulled, the control plate spring 406 will slowly retract. It should be noted that the control plate spring 406 is always in an extended state to facilitate smoother retraction of the push-pull connecting frame 401. Therefore, when the push-pull connecting frame 401 is pulled back, the clamping plates 404 will move closer to each other, thereby clamping the workpiece 8 and facilitating loading and unloading.

[0031] It should be noted that a base platform 1 is provided on one side of the pad printing machine 7, and a robotic arm 2 is provided at the top of the base platform 1. The movable end of the robotic arm 2 is fixedly connected to the support platform 504. The pad printing area of ​​the pad printing machine 7 is provided with a printing table 701, and the workpiece 8 is located on the top of the printing table 701.

[0032] In an optional implementation, during pad printing, the workpiece 8 is placed on top of the printing table 701, and the robotic arm 2 can flexibly drive the loading and unloading structure 3 to perform loading and unloading operations.

[0033] For example, a suction cup 601 is provided at the bottom of the suction carrier 6, and a negative pressure pump is fixedly provided at the top of the suction carrier 6. The negative pressure pump is in communication with the suction cup 601. A side bracket 602 is fixedly provided on one side of the suction cup 601. The side bracket 602 is fixedly provided on the lower surface of the transmission belt 503. A notch 5041 is provided through the top of the support platform 504. The notch 5041 allows the negative pressure pump to move inside it.

[0034] In an alternative embodiment, the negative pressure pump is not shown in the figure. It is prior art and will not be described in detail. The negative pressure pump can be activated when the suction cup 601 is picking up the workpiece 8. The notch 5041 is opened to provide space for the negative pressure pump to move when it is replaced.
