Description

Technical Field

[0001] This utility model belongs to the field of finished touch screen inspection technology, and in particular relates to a multi-angle observation frame for finished touch screen inspection. Background Technology

[0002] Touchscreens, as a key functional component for human-computer interaction, are widely used in smartphones, tablets, industrial control terminals, medical display devices, in-vehicle central control systems, and various intelligent interactive terminals. To ensure the visual performance and touch response of the final product, finished touchscreens must undergo rigorous appearance and functional inspections before leaving the factory, focusing on defects such as surface scratches, interlayer bubbles, color deviations, and misalignment, thereby guaranteeing product quality.

[0003] Currently, the industry commonly uses rotary clamps to hold and fix touchscreens, allowing for manual rotation to observe the surface condition and edge details from different angles. However, existing clamps often use rigid material structures and fix the touchscreen by direct pressing or snapping. During clamping, localized stress concentration or improper operation can easily cause scratches on the touchscreen surface, chipping at the edges, or damage to the coating layer, severely affecting product yield and inspection reliability.

[0004] Therefore, there is a particular need for a multi-angle observation frame for inspecting finished touch screen products to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing rotary clamps that easily damage touch screens due to rigid clamping, thus affecting product yield and inspection reliability, this utility model provides a multi-angle observation frame for inspecting finished touch screen products.

[0006] This utility model is achieved through the following technical means: A multi-angle observation frame for inspecting finished touch screen products includes a base, a motor, a bidirectional cylinder, a connecting plate, a fixing rod, a sliding sleeve, a connecting rod, an electric push rod, a fixed frame, an air chamber, a push plate, a guide rod, a spring, a limiting plate, an air bag, an air tube, and a controller. The motor is mounted on the upper part of the base, and the bidirectional cylinder is mounted on the output shaft of the motor. Connecting plates are installed at the ends of the two piston rods of the bidirectional cylinder. Two fixing rods are fixedly connected to the output shaft of the motor, and a sliding sleeve is slidably mounted on the outside of each fixing rod. Two connecting plates are fixedly connected to two sliding sleeves respectively, and connecting rods are fixedly connected to the ends of the two sliding sleeves that are far apart from each other. Each connecting rod is equipped with an electric push rod at both ends. Each electric push rod has a fixed frame at the piston rod end. Each fixed frame has an air chamber fixedly connected to it. Two guide rods are slidably arranged on each fixed frame. A push plate is fixedly connected to one end of each guide rod. The push plate slides into the corresponding air chamber. A limit plate is fixedly connected between the other ends of two adjacent guide rods. A spring is sleeved on the outside of each guide rod. The two ends of the spring are connected to the corresponding fixed frame and the corresponding limit plate, respectively. Two airbags are fixedly connected to each fixed frame. Each airbag is connected to the corresponding air chamber through two air pipes. The controller is also installed on the upper part of the base. The motor, bidirectional cylinder and electric push rod are all electrically connected to the controller.

[0007] Furthermore, it is particularly preferred that the device also includes a lens, which is placed at the bottom of the base.

[0008] In addition, it is particularly preferred that the base also includes lighting lamps, with two side-by-side lighting lamps mounted on the lower part of the base, the lighting lamps being electrically connected to the controller, and the lens being located between the two lighting lamps.

[0009] Furthermore, it is particularly preferred that the edge of the push plate that contacts the air chamber is covered with a sealing gasket.

[0010] Furthermore, it is particularly preferred that the limiting plate is made of rubber.

[0011] Furthermore, it is particularly preferred that the airbag has two hemispherical structures.

[0012] The beneficial effects of this utility model are as follows: 1. Through the linkage and cooperation of electric push rod, fixed frame, air chamber, push plate, guide rod, spring, limit plate, air bag and air tube, the adaptive flexible clamping of the touch screen body is realized, which effectively avoids scratches, chipping or coating damage to the touch screen body caused by traditional rigid clamping, and improves product yield and inspection safety.

[0013] 2. By combining a lens with a lighting lamp and using a motor-driven multi-angle rotation function, the system enables all-round imaging and manual visual inspection of defects on the surface of the touch screen, thereby improving inspection efficiency. Attached Figure Description

[0019] Example: A multi-angle observation frame for inspecting finished touch screen products, such as... Figures 1-4As shown, the system includes a base 1, a lens 2, an illumination lamp 3, a motor 5, a two-way cylinder 6, a connecting plate 7, a fixing rod 8, a sliding sleeve 81, a connecting rod 9, an electric push rod 10, a fixing frame 101, an air chamber 11, a push plate 12, a guide rod 13, a spring 14, a limiting plate 15, an airbag 16, an air pipe 17, and a controller 18. The lens 2 is placed at the lower part of the base 1. Two illumination lamps 3 are bolted to the lower part of the base 1, and the lens 2 is located between the two illumination lamps 3. The motor 5 is bolted to the upper part of the base 1, and the output shaft of the motor 5 extends horizontally forward. The two-way cylinder 6 is bolted to the output shaft of the motor 5. The two piston rods of the bidirectional cylinder 6 are each bolted to a connecting plate 7. Two symmetrically distributed fixing rods 8 are fixedly connected to the output shaft of the motor 5. A sliding sleeve 81 is slidably mounted on the outside of each fixing rod 8. The two connecting plates 7 are respectively fixedly connected to the two sliding sleeves 81. A connecting rod 9 is fixedly connected to the ends of the two sliding sleeves 81 that are far apart from each other. Electric push rods 10 are bolted to both ends of each connecting rod 9. A fixing frame 101 is bolted to the piston rod end of each electric push rod 10. An air chamber 11 is fixedly connected to each fixing frame 101. Two symmetrically distributed... The guide rods 13 are each fixedly connected to a push plate 12 at one end. The push plate 12 slides into the corresponding air cavity 11, and the edge of the push plate 12 in contact with the air cavity 11 is covered with a sealing gasket to ensure reliable gas sealing inside the air cavity 11 during the sliding of the push plate 12, effectively preventing gas leakage. A limit plate 15 is fixedly connected between the other ends of two adjacent guide rods 13. The limit plate 15 is made of rubber and has anti-scratch function to prevent rigid contact damage to the touch screen body 4. A spring 14 is sleeved on the outside of each guide rod 13. The two ends of the spring 14 are respectively connected to the corresponding fixing frame 101 and the corresponding limit plate 15, thereby providing support for the limit plate 15. For providing reset elasticity, two vertically distributed airbags 16 are fixedly connected to each fixed bracket 101. Each airbag 16 is connected to the corresponding air chamber 11 through two symmetrically distributed air tubes 17. The airbag 16 has two hemispherical structures to fit the surface of the touch screen body 4. The controller 18 is also fixed to the upper part of the base 1 through a coupling and is located to the right rear of the motor 5. The lighting lamp 3, motor 5, bidirectional cylinder 6 and electric push rod 10 are all electrically connected to the controller 18. The controller 18 is a programmable logic controller, model Huichuan Easy521-24T4DT, which can realize stable electrical linkage control of multiple electrical components.

[0020] In use, the operator first activates the bidirectional cylinder 6 via controller 18, causing the two piston rods of the bidirectional cylinder 6 to extend and drive the two sliding sleeves 81 to slide outward along the two fixed rods 8, thereby widening the distance between the left and right electric push rods 10. Then, the touchscreen body 4 to be tested is placed horizontally within the space enclosed by the four fixed brackets 101. The operator then retracts the two piston rods of the bidirectional cylinder 6, causing the two sliding sleeves 81 to slide inward, narrowing the distance between the left and right electric push rods 10. The bidirectional cylinder 6 is then deactivated, and the four electric push rods 101 are activated. Push rod 10 controls the piston rods of four electric push rods 10 to extend synchronously, driving the four fixed brackets 101 to move inward synchronously, so that the four limiting plates 15 contact the four corners of the touch screen body 4. When in contact, the four limiting plates 15 are moved outward by the reaction force of the touch screen body 4, compressing the spring 14. When the limiting plates 15 move outward, they drive the guide rod 13 to move outward, so that the push plate 12 penetrates into the air cavity 11, and the gas in the air cavity 11 is forced into the upper and lower air bags 16 through the air pipe 17, so that the air bags 16 are inflated and expanded, tightly fitting and flexibly clamping. The touchscreen body 4 is secured with a buffer around its edges. After clamping, two lights 3 are turned on to provide a uniform light source. Lens 2 is used to photograph the surface of the touchscreen body 4. During the photographing process, motor 5 is started. The output shaft of motor 5 drives the bidirectional cylinder 6, four electric push rods 10, and the touchscreen body 4 to rotate, allowing the operator to visually inspect the surface of the touchscreen body 4 for defects such as scratches, bubbles, color differences, and misalignment from multiple angles. At the same time, lens 2 captures multi-angle images. After the inspection and photographing are completed, motor 5 is turned off, and the piston rods of the four electric push rods 10 are controlled to retract synchronously, causing the four fixing brackets 101 to move outward. The limiting plate 15 is disengaged from the touchscreen body 4, and spring 14 returns to its original state, pushing the limiting plate 15 to move inward to reset. Guide rod 13 drives push plate 12 to move inward to reset synchronously. The four electric push rods 10 are turned off. During the reset process of push plate 12, the gas in airbag 16 is re-inhaled into air chamber 11 through air tube 17. Airbag 16 then deflates and contracts, returning to its original shape. Finally, the operator safely removes the touchscreen body 4, completing the inspection process.
