The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0019] The general idea of the present invention is: in order to solve the problem of uneven ink thickness, spots, convex points, light leakage and other defective products in the production process of pad printing ink in the prior art, the fixture provided by the present invention is designed with a glass bearing part along the body shape of the special-shaped curved glass, and a light source shielding block is designed in the area outside the ink, so that the light source only passes through the ink area; when in use, the glass product is placed on the fixture, the LED light strip installed on the fixture is turned on, and the fixture is rotated to observe with the eyes whether there are undesirable phenomena such as uneven ink thickness, spots, convex points, light leakage and so on in the ink area, and then determine whether the quality of the ink production is qualified or unqualified; thereby, the efficiency of the quality control of the special-shaped curved glass ink is greatly improved.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0021] Figure 1 Shown is an exploded schematic diagram of a fixture for detecting ink quality of special-shaped curved glass provided by one embodiment of the present invention; Figure 2 The figure shows the front view of a fixture for detecting the ink quality of special-shaped curved glass provided by an embodiment of the present invention. Figure 1 and 2As shown, the fixture provided by the present invention for inspecting the quality of ink on irregularly shaped curved glass comprises a positioning base 100, a light source blocking block 200, an LED light strip 300, and a fixture gripper 500. The light source blocking block 200 and the LED light strip 300 are mounted on the upper surface of the positioning base 100, and the fixture gripper 500 is mounted on the lower surface of the positioning base 100. During use, the fixture is placed stably on a quality inspection workbench; the irregularly shaped curved glass 400 to be inspected is sucked onto the fixture using a glass suction pen 600 so that it aligns with the upper surface of the light source blocking block 200; the power switch of the LED light strip 300 is turned on, and the fixture gripper 500 is used to rotate the fixture back and forth to visually observe the ink area and determine whether the ink production quality is qualified; after the inspection is completed, the glass product is removed using the glass suction pen 600. Since the upper surface of the light source blocking block 200 is designed along the shape of the standing position of the special-shaped curved glass 400, only the standing position of the glass product contacts the fixture, and the surface of the glass product does not contact the fixture; the light source blocking block can effectively block the light source on the surface of the special-shaped curved glass, so that the light source only illuminates the ink area, so that the good and defective products of the ink production can be quickly identified by the eyes; the fixture can be easily and comfortably grasped by the fixture gripper 500, and the gripper is connected to the positioning base and can rotate 350 degrees back and forth, thereby quickly detecting the ink quality around the special-shaped curved glass without tilting the head to observe the ink; by placing the glass suction pen into the fixture, it can effectively avoid secondary defects of the glass product caused by dirt caused by touching the glass surface with the hand; thus, it can effectively replace the previous method of detecting ink quality by holding the glass by hand, and can improve the detection efficiency by at least 50%.

[0022] Specifically, in one embodiment of the present invention, Figure 3 As shown, the top of the positioning base 100 is provided with a blocking block mounting portion 110 for mounting the light source blocking block 200 and an annular groove 120 arranged around the blocking block mounting portion 110 and for mounting the LED light strip 300. Furthermore, the positioning base 100 is made of black ABS material that is opaque and has a lower hardness than glass, which can prevent scratches on glass products. Furthermore, in order to better support the special-shaped curved glass, the shape of the upper surface of the accommodating space formed by the two side edges of the positioning base 100 is adapted to the outer shape of the standing position of the special-shaped curved glass, so as to ensure that after the light source blocking block is installed, there is no gap between the upper surface of the light source blocking block and the two side edges.

[0023] Specifically, in one embodiment of the present invention, the light source blocking block 200 includes a glass bearing portion 210 for bearing the special-shaped curved glass 400 and a blocking portion 220 disposed below the glass bearing portion 210. The shape of the glass bearing portion 210 is the same as the outer shape of the standing position of the special-shaped curved glass 400, and the blocking portion 220 is fixed in the blocking block mounting portion 110. Furthermore, the light source blocking block is fixed to the positioning base with two hexagon socket screws. In the present invention, by designing the glass bearing portion of the glass product along the outer shape of the standing position of the special-shaped curved glass, the glass can be fixed on the positioning base; the light source blocking block can effectively block the light source on the surface of the special-shaped curved glass, so that the light source only illuminates the ink area, that is, the edge area of the glass bearing portion; at the same time, the light source blocking block is made of black ABS material that is opaque and has a lower hardness than glass, which can prevent the glass product from being scratched or scratched.

[0024] Specifically, in one embodiment of the present invention, the LED light strip 300 is fixed in the annular groove 120. When in use, the glass product is placed on the fixture, and the LED light strip 300 installed on the fixture is turned on to illuminate the glass placed above it. Due to the light source shielding block designed in the area outside the ink, the light emitted by the LED light strip only passes through the ink area.

[0025] Specifically, in one embodiment of the present invention, in order to better use the clamp, a clamp gripper 500 is installed at the bottom of the clamp. During use, the clamp is rotated by the clamp gripper 500 to observe with the eyes whether there are any undesirable phenomena such as uneven ink thickness, spots, bumps, light leakage, etc. in the ink area, and then determine whether the quality of the ink production is qualified or unqualified. Furthermore, in order to allow the clamp to rotate smoothly, the clamp gripper 500 is connected to the positioning base 100 through a bearing 510 and a hexagon socket screw 520 embedded in the bottom. The clamp gripper and the positioning base are designed to be connected by a bearing and can rotate 350 degrees back and forth, which can quickly detect the ink quality around the special-shaped curved glass without having to tilt the head to observe the ink.

[0026] Specifically, in one embodiment of the present invention, Figure 4 As shown, to prevent the LED light source power cord from getting tangled, the bottom of the positioning base 100 is provided with a clamp rotation angle limit slot 130, and the clamp gripper 500 is mounted in the clamp rotation angle limit slot 130. By designing the clamp rotation angle limit slot in the positioning base, the clamp can rotate back and forth 350 degrees, thereby preventing the LED light source power cord from getting tangled.

[0027] When using the fixture for detecting the quality of ink on special-shaped curved glass provided by the present invention, the glass product can be placed in the fixture through a glass suction pen, which can effectively avoid secondary defects in the glass product caused by dirt caused by touching the glass surface with hands. At the same time, the fixture is designed with a bearing part for the special-shaped curved glass designed along the outer shape of the standing position of the special-shaped curved glass. Only the standing position of the glass product contacts the fixture, and the surface of the glass product does not contact the fixture. The light source blocking block can effectively block the light source on the surface of the special-shaped curved glass, so that the light source only illuminates the ink area. In this way, the good and bad products of the ink production can be quickly identified by the eyes, avoiding eye fatigue and improving work efficiency. The fixture can be easily and comfortably grasped by the clamping gripper, and the clamping gripper and the positioning base are designed to be connected by bearings. The angle can be rotated to quickly detect the ink quality around the special-shaped curved glass without having to tilt the head to observe the ink. As a result, the efficiency of the ink quality inspection of special-shaped curved glass is greatly improved.
