Description
A pad printing fixture for product pad printing Technical Field
[0001] This utility model belongs to the field of pad printing equipment technology, specifically relating to a pad printing fixture for product pad printing. Background Technology
[0002] Pad printing equipment is a specialized printing device used for printing on the surfaces of objects with various complex shapes and materials. Current technology typically employs a single approach: fixing the pad printing fixture to the equipment, manually loading the product onto the fixture, and then starting the printing process. After printing, the product is removed and placed on a drying line to dry the ink. Throughout the printing process, the fixture must remain stationary after precise positioning to prevent inaccurate product placement, which could lead to ink spillage in areas requiring transparency, necessitating subsequent laser engraving and reducing production efficiency. However, in practice, because products are generally small, manual handling after printing can easily expose the product to undried ink, resulting in ink overflow or fingerprints, reducing the yield rate.

[0020] Example:
[0021] As shown in Figures 1-4, this embodiment provides a pad printing fixture for product pad printing, including a fixed fixture 1 installed on a pad printing device and an interchangeable fixture 2 positioned and supported on the upper end of the fixed fixture 1. The interchangeable fixture 2 is detachably installed on the fixed fixture 1, and the stability of the interchangeable fixture 2 can also be ensured by the fixed fixture 1. The upper end of the interchangeable fixture 2 is provided with at least two product loading stations for loading products 3, which can pad print at least two products 3 at a time. The product loading stations can be the same as those in the prior art, which can ensure the stable setting of the products 3. The interchangeable fixture 2 is positioned at the top to facilitate the movement of the product 3 along with it. At the same time, at least two precision positioning posts 101 are installed in the middle of the upper end of the fixed fixture 1, and at least two precision positioning guide sleeves 201 are installed at the lower end of the interchangeable fixture 2. The upper part of each precision positioning post 101 is matched and inserted into a precision positioning guide sleeve 201. Thus, through the cooperation between the precision positioning post 101 and the precision positioning guide sleeve 201, the precise positioning of the interchangeable fixture 2 on the fixed fixture 1 is ensured, which indirectly ensures the precise positioning of the product 3 on the pad printing equipment.
[0022] This invention allows for the precise pre-installation of the fixed fixture 1 onto the pad printing equipment. During operation, the interchangeable fixture 2, with the product 3 loaded on its upper end, is then installed onto the fixed fixture 1. The precise engagement of the precision positioning pin 101 and the precision positioning guide sleeve 201 ensures the precise positioning of the interchangeable fixture 2 on the fixed fixture 1, thereby indirectly guaranteeing the precise positioning of the product 3 on the pad printing equipment. This ensures that areas requiring transparency are not transferred to the ink during pad printing, eliminating the need for subsequent laser engraving. Furthermore, the interchangeable fixture 2 can load at least two products 3 at a time. After pad printing, the interchangeable fixture 2 can be directly removed from the fixed fixture 1 and placed on the drying line to dry the ink, preventing direct contact between human hands and products with undried ink, thus effectively improving production efficiency and yield.
[0023] As a preferred embodiment of this invention, it should be further explained that a positioning mounting groove 102 is provided in the middle of the upper end of the fixed clamp 1, and the lower part of the interchangeable clamp 2 is set in the positioning mounting groove 102, which can further ensure the stability of the interchangeable clamp 2; all the precision positioning pins 101 are installed on the inner bottom surface of the positioning mounting groove 102. When the interchangeable clamp 2 is placed in the positioning mounting groove 102, the precision positioning pins 101 can be inserted into the precision positioning guide sleeve 201 to directly ensure the positioning accuracy of the interchangeable clamp 2.
[0024] As a preferred embodiment of this example, it should be further explained that the middle of both sides of the positioning mounting groove 102 is provided with a hand-holding position 103, which makes it easy for a person to grasp the middle of both sides of the interchangeable fixture 2 from the two hand-holding positions 103, thus leaving space for the hand, making the placement of the interchangeable fixture 2 more stable and the picking up of the interchangeable fixture 2 easier; all the product loading stations are distributed at both ends of the interchangeable fixture 2, thus avoiding the product 3 between the two hand-holding positions 103, so that when picking up and placing the interchangeable fixture 2, the person's hand can also avoid contact with the product 3.
[0025] As a preferred embodiment of this invention, it should be further explained that the precision positioning guide sleeve 201 is embedded inside the interchangeable fixture 2, and the precision positioning guide sleeve 201 is fixed inside the interchangeable fixture 2, without affecting the lower end of the interchangeable fixture 2 being supported on the fixed fixture 1, thereby ensuring the stability of the interchangeable fixture 2. The lower part of the precision positioning post 101 is installed inside the fixed fixture 1, ensuring the stability of the precision positioning post 101. The upper end of the precision positioning post 101 has a ball head structure, which makes it easier for the upper part of the precision positioning post 101 to be inserted into the precision positioning guide sleeve 201. It should be noted that the upper part of the precision positioning post 101 can be completely inserted into the precision positioning guide sleeve 201 without affecting the lower end of the interchangeable fixture 2 being supported on the fixed fixture 1.
[0026] As a preferred embodiment of this invention, it should be further explained that the precision positioning post 101 is made of steel and the precision positioning guide sleeve 201 is made of copper. The combination of the two can reduce wear. The precision positioning post 101 is made of steel to ensure that it will not rust, thereby ensuring its accuracy. The precision positioning guide sleeve 201 is made of copper, which facilitates processing.
[0027] As a preferred embodiment of this example, it should be further explained that each interchangeable fixture 2 corresponding to each product loading station is provided with a vacuum suction positioning hole 202 extending through its upper and lower ends. The lower end of each vacuum suction positioning hole 202 is connected to a vacuum suction cup 104. The lower end of the interchangeable fixture 2 is reserved with a suction cup clearance groove, which facilitates the contact of the lower end face of the interchangeable fixture 2 with the fixed fixture 1 while ensuring that the vacuum suction cup 104 can be well aligned with the vacuum suction positioning hole 202. The vacuum suction cup 104 is installed on the fixed fixture 1 to ensure its stability. A vacuum suction connector 105 connected to all vacuum suction cups 104 is installed on one side of the fixed fixture 1. The vacuum suction connector 105 can be connected to equipment such as a vacuum pump. Before pad printing, the vacuum pump can be turned on to evacuate the vacuum suction connector 105, so that a negative pressure is formed in the vacuum suction positioning hole 202, thereby better ensuring the stability of the product 3 at the product loading station. It should be noted that, in practice, the number of vacuum suction connectors 105 can be set according to the actual situation and there is no specific limit. As shown in Figures 1 and 3, two vacuum suction connectors 105 can be set, and the two vacuum suction connectors 105 can be connected to the vacuum suction cups 104 at both ends of the interchangeable fixture 2 respectively.
[0028] As a preferred embodiment of this invention, it should be further noted that both ends of the fixing clamp 1 are provided with screw mounting holes 106 to facilitate installation on the pad printing equipment by screws, thereby ensuring the stability of the screw mounting holes 106 on the pad printing equipment.
[0029] As a preferred embodiment of this example, it should be further explained that the screw mounting hole 106 is an elongated hole extending along the width direction of the fixing clamp 1. In the actual process of installing the fixing clamp 1, the position of the fixing clamp 1 can be finely adjusted, thereby ensuring the accuracy of the fixing clamp 1 during installation, and thus ensuring the accuracy of the subsequent product 3 on the pad printing equipment.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
