Description

Technical Field

[0001] This utility model belongs to the field of production equipment technology, and more specifically, it relates to the pressure gauge device of LCD instrument production equipment. Background Technology

[0002] Automotive LCD instrument clusters typically consist of a detection device, a processor, and a display. With technological advancements, fully digital displays have become the mainstream design. The processor is integrated into the display, while the detection device is externally mounted to the corresponding component in the vehicle, transmitting the detected information to the display. The assembly process generally involves first fixing the processor and the internal structure of the display to the back panel of the display, and then pressing the front frame of the display onto the back panel for connection and fixation. The detection device is usually connected to the display after installation in the vehicle.

[0003] However, in practical use, excessive pressure from traditional rigid pressing can easily cause the LCD screen to crack, and manual placement of the LCD screen can easily lead to misalignment, resulting in more defective products, affecting production efficiency and increasing production costs. Therefore, in view of this, we have researched and improved the existing structure and its shortcomings to provide a pressure gauge device for LCD instrument production equipment, aiming to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pressure gauge device for LCD instrument production equipment, thereby addressing the issues raised in the background art.

[0005] The purpose and effectiveness of the pressure gauge device in this utility model's LCD instrument production equipment are achieved through the following specific technical means:

[0006] The pressure gauge device of the LCD instrument cluster production equipment includes a main body, a lifting mechanism, and a positioning mechanism. The main body includes a base, a frame is mounted on the upper end of the base, and each of the four pillars of the frame has a sliding rod inside. The lower end of the base has four sets of support legs. The lifting mechanism is mounted on the frame and includes an upper connecting plate and a lower connecting plate. Each of the four ends of the upper and lower connecting plates has a sliding block that is slidably connected to the sliding rod. The positioning mechanism includes a movable tray, and a sliding guide rail is provided on the upper end of the base. The sliding guide rail is slidably connected to the movable tray.

[0007] Furthermore, a vibration sensor is provided inside the lower end of the base, and a piezoelectric ceramic actuator is provided on one side of the vibration sensor.

[0008] The beneficial effect of adopting the above-mentioned further solutions is that by installing and using vibration sensors and piezoelectric ceramic actuators, it is easy to counteract the high-frequency vibrations generated during equipment operation, reduce mechanical damage, and extend the service life of the device.

[0009] Furthermore, the lifting mechanism also includes a drive cylinder, which is installed on the top of the frame. The lower end of the drive cylinder is provided with a telescopic rod that passes through the top of the frame, and the lower end of the telescopic rod is fixedly connected to an upper connecting plate.

[0010] Furthermore, the lower end face of the upper connecting plate is provided with multiple sets of buffer damping springs, and the lower ends of the multiple sets of buffer damping springs are fixedly connected to the upper surface of the lower connecting plate.

[0011] The beneficial effects of adopting the above-mentioned further solution are that by driving the telescopic rod to move the cylinder, the upper and lower connecting plates can move linearly, avoiding scratches during pressing. The installation and use of buffer damping springs facilitates staged pressure control, preventing impact damage and thus preventing product damage.

[0012] Furthermore, a vacuum chamber is provided at the lower end of the lower connecting plate, and multiple sets of miniature vacuum suction cups are connected to the lower end of the vacuum chamber. The miniature vacuum suction cups are arranged in an array at the lower end of the vacuum chamber. Multiple sets of negative pressure channels are connected to the upper end of the vacuum chamber, and a vacuum generator is connected to the other end of the negative pressure channel. The vacuum generator is installed at the top of the upper connecting plate.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of the vacuum generator, negative pressure channel, vacuum chamber and miniature vacuum suction cup facilitates product adsorption and avoids slippage.

[0014] Furthermore, infrared receivers are provided at both ends of the mobile tray, and infrared transmitters are provided on the front and rear lower sides of the top of the frame. The infrared transmitters and receivers form a photoelectric beam-through module.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of the infrared transmitter and receiver facilitates the front and rear positioning of the mobile tray.

[0016] Furthermore, the movable tray is provided with a groove, a drive motor is provided on one side of the groove, the output end of the drive motor is connected to a bidirectional lead screw, and two sets of clamping blocks are symmetrically provided on the bidirectional lead screw, with protruding points on the opposite surfaces of the two sets of clamping blocks.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by driving the bidirectional lead screw to rotate through the drive motor, the two sets of clamping blocks can move towards or away from each other, thereby achieving centering and clamping of the product.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The pressure gauge device of this type of LCD instrument production equipment uses a drive motor to rotate a bidirectional lead screw, which allows two sets of clamping blocks to move in opposite directions, thereby achieving centering and clamping of the product. The clamped and fixed product enters the base along a sliding guide rail. The installation and use of the infrared transmitter and receiver facilitates the front and rear positioning of the moving tray. The installation and use of a vacuum generator, negative pressure channel, vacuum chamber, and miniature vacuum suction cup facilitates product adsorption and prevents slippage. Subsequently, a drive cylinder drives a telescopic rod to move the upper and lower connecting plates linearly, causing the product to descend for pressing, preventing scratches during pressing. The installation and use of a buffer damping spring facilitates staged pressure control, preventing impact damage to the product. Furthermore, the installation and use of a vibration sensor and piezoelectric ceramic actuator help to counteract high-frequency vibrations generated during equipment operation, reducing mechanical damage and extending the service life of the device. This utility model has a simple and reasonable structure, novel design, and simple and convenient assembly, possessing high practical value. Attached Figure Description
