Description

Technical Field

[0001] This utility model relates to the technical field of pad printing feeders, and in particular to a fully automatic pad printing feeder. Background Technology

[0002] In the field of pad printing, traditional feeding and pad printing production methods have many drawbacks. Currently, many manufacturers still use a production mode of manual feeding combined with semi-automatic pad printing equipment. Manual feeding is not only inefficient and difficult to meet the needs of large-scale production, but also has poor stability, which can easily lead to deviations in feeding position, affecting pad printing quality and increasing the defect rate.

[0003] While semi-automatic pad printing equipment alleviates the burden of manual labor to some extent, the lack of efficient coordination and automated control between its various processes prevents smooth automated operation of materials in feeding, transferring, printing, and post-processing. For example, manual assistance is often required during the transfer of materials from the feeding area to the pad printing station, which not only reduces production efficiency but also increases production costs. Furthermore, traditional equipment lacks the ability to finely process and precisely position materials, making it difficult to guarantee consistent product quality in complex patterns or high-precision pad printing operations.

[0004] With the increasing market demand for pad printing products and the ever-increasing requirements for product quality, it is urgent to develop a fully automatic pad printing feeder that can achieve automated material feeding, precise pad printing, and efficient post-processing. This is to solve the problems of low efficiency and unstable quality in existing production methods and meet the development needs of modern manufacturing. Utility Model Content

[0043] Specifically, a CCD industrial camera is installed at the upper part of the output end of the feeding module 2 to take pictures and identify the materials, and in conjunction with the RS4 robotic arm feeding module 5, the materials are picked up and fed into the secondary feeding component 32 of the pad printing module 3.

[0044] Two sets of pre-pressing components are provided on one side of the pad printing assembly 34. Each pre-pressing component includes a pre-pressing frame fixedly connected to the support plate 348 of the pad printing table 341, and a pressure plate fixedly connected to the pre-pressing frame. The pressure plate is provided with a protrusion adapted to the material. The pre-pressing components are used to press and fix the material placed in the pad printing assembly 34 to improve the stability of the pad printing process.

[0045] A feeding port is provided on the side of the frame 1 near the feeding module 2. The operator feeds the material into the feeding module 2 through the feeding port. The CCD industrial camera identifies the position of the material. The RS4 robotic arm feeding module 5 grabs the product and places it into the secondary feeding component 32. The secondary feeding component 32 clamps the product, adjusts the angle and position of the material, and places it into the circular track circulation component 33. The circular track circulation component 33 drives the material to move to the pre-pressing station. The pre-pressing component pre-presses the material. After pre-pressing, it moves to the pad printing station. The pad printing component 34 performs the pad printing operation on the material. During the pad printing process, the locking component 35 lifts up to limit and stop the circular track circulation component 33. After the pad printing is completed, the material moves to the unloading station. The discharge gripper 45 clamps the material into the baking oven 46 for baking. The conveyor belt 47 set under the baking oven 46 moves the material to the unloading plate 48 to complete the discharge.

[0046] The automated circulating feeding component features a double-layer transmission device design that disperses materials by allowing them to pass through the upper layer and then fall to the lower layer, reducing the chance of material stacking and improving the picking effectiveness of the RS4 robotic arm's feeding module 5, thus enhancing the efficiency of inter-step coordination. The RS4 robotic arm's feeding module 5 works in conjunction with a CCD industrial camera to pick up materials. The RS4 robotic arm is equipped with a gripping part and a negative pressure adsorption part, which can be flexibly replaced according to different product models, ensuring strong adaptability and compatibility.

[0073] The working principle of this utility model:

[0074] A feeding port is provided on the side of the frame 1 near the feeding module 2. The operator feeds the material into the feeding module 2 through the feeding port. The CCD industrial camera identifies the position of the material. The RS4 robotic arm feeding module 5 grabs the product and places it into the secondary feeding component 32. The secondary feeding component 32 clamps the product, adjusts the angle and position of the material, and places it into the circular track circulation component 33. The circular track circulation component 33 drives the material to move to the pre-pressing station. The pre-pressing component pre-presses the material. After pre-pressing, it moves to the pad printing station. The pad printing component 34 performs the pad printing operation on the material. During the pad printing process, the locking component 35 lifts up to limit and stop the circular track circulation component 33. After the pad printing is completed, the material moves to the unloading station. The discharge gripper 45 clamps the material into the baking oven 46 for baking. The conveyor belt 47 set under the baking oven 46 moves the material to the unloading plate 48 to complete the discharge.

[0075] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
