Made of high-strength alloy material, it has anti-vibration pads at the bottom to effectively reduce vibration interference during testing. An adjustable dispensing mechanism 2 is fixedly connected to the top of the main body 1. This mechanism can adjust the position and angle of the dispensing head according to testing requirements, adapting to testing scenarios of different models of dispensing machines. An inspection positioning component 3 is provided on the top of the main body 1 for precise positioning of the workpiece to be tested, ensuring the accuracy of the dispensing trajectory detection. The inspection positioning component 3 includes an adjustable slide rail 31, which adopts a linear guide structure and has high-precision guiding performance, ensuring the smooth movement of the electrically controlled slide table 32. The bottom of the adjustable slide rail 31 is fixedly connected to the center of the upper surface of the main body 1. The electrically controlled slide table 32 is slidably connected to the outer side of the adjustable slide rail 31 and is driven by a servo motor. It can achieve precise displacement along the adjusting slide rail 31, with a displacement accuracy of ±0.01mm. The top of the electrically controlled slide table 32 is provided with a positioning slide groove 33 and a limiting guide groove 34 in sequence. The positioning slide groove 33 is used to limit the sliding direction of the electric clamp 35, and the limiting guide groove 34 can prevent the electric clamp 35 from deviating during the clamping process. The electric clamp 35 is slidably connected between the positioning slide groove 33 and the limiting guide groove 34. It adopts an electric drive method, and the clamping force can be steplessly adjusted by the control mechanism to adapt to the clamping requirements of workpieces of different materials. There are two electric clamps 35, which are mirrored along the central axis of the electrically controlled slide table 32 to form a symmetrical clamping structure, ensuring that the workpiece is subjected to uniform force and avoiding clamping deformation. Height sensors 36 are fixedly connected to the front and rear outer walls of the electrically controlled slide table 32. Using the laser ranging principle, they can monitor the distance between the dispensing head and the workpiece surface in real time, providing data support for the detection of dispensing height parameters.
[0020] Reference Figure 1 , Figure 2 and Figure 4The top of the main body 1 is equipped with an inspection component 4, which integrates multiple detection function modules to achieve comprehensive detection of dispensing volume, dispensing trajectory, and dispensing dot morphology. The inspection component 4 includes an inspection box 41, which adopts a closed box structure and is equipped with a constant temperature and humidity control module to avoid the influence of environmental factors on the detection accuracy. The bottom of the inspection box 41 is fixedly connected to the right side of the upper surface of the main body 1. A weighing and analytical balance 42 is hinged to the surface of the inspection box 41, with an accuracy of up to 0.1 mg, for accurately measuring the amount of adhesive dispensed in a single application. The balance surface is coated with an anti-adhesive coating for easy cleaning and maintenance. The interior of the inspection box 41 is fixedly connected with a box door 43, which is made of transparent acrylic material for easy observation. The internal inspection process also serves as a dustproof measure. Sealing strips are provided along the edges of the door 43 to enhance the box's airtightness. A mounting frame 44, constructed of lightweight and high-strength aluminum alloy, is fixedly connected to the top of the inspection box 41, providing stable support for the inspection equipment. An electric lead screw 45, using a ball screw structure, is fixedly installed on the inner wall of the lower surface of the mounting frame 44, providing high transmission efficiency and precise positioning. This provides horizontal movement power for the CCD vision inspection scanner 48. One end of the electric lead screw 45 is rotatably connected to the inner wall of the mounting frame 44, while the other end passes through the outer wall of the mounting frame 44 and is fixedly connected to a drive motor. This servo motor allows for forward and reverse rotation control and speed adjustment. To meet the needs of different scanning speeds, the outer side of the electric lead screw 45 is threadedly connected to a lead screw slide 46, which works with the electric lead screw 45 to achieve linear motion. Wear-resistant sliders are provided at the contact points between the slide and the mounting bracket 44 to reduce wear during movement. The outer side of the lead screw slide 46 is slidably connected to the inner wall of the lower surface of the mounting bracket 44. An electric lifting frame 47 is fixedly connected to the lower surface of the lead screw slide 46, employing a multi-stage telescopic structure to precisely adjust the height of the CCD visual inspection scanner 48, with an adjustment range of 0-300mm. The lower surface of the electric lifting frame 47 is fixedly connected to the CCD visual inspection scanner 48, which has a resolution of up to 12 million pixels and can capture the two-dimensional morphological parameters of adhesive dots, such as diameter, etc. The image processing algorithm automatically analyzes roundness, positional deviation, etc. The outer surface of the electric lifting frame 47 is fixedly connected to the supplementary light lamp 49, which provides a uniform and stable light source and eliminates the interference of workpiece surface reflection on image acquisition. The supplementary light lamp 49 consists of a ring lamp and a connecting frame. There are two connecting frames, which are mirrored along the central axis of the lead screw slide table 46, and the inner sides of the two connecting frames are fixedly connected to the outer wall of the ring lamp. The ring structure can achieve 360° no dead angle illumination, ensuring that all parts of the glue point can be clearly captured. The ring lamp is set at the bottom outer edge of the CCD visual inspection scanner 48 and is arranged coaxially with the scanner lens to avoid the lighting shadow affecting the inspection accuracy.
[0021] Working Principle: During use, the syringe of the dispensing machine to be tested is installed on the adjusting dispensing mechanism 2. The position and angle of the dispensing head are adjusted according to the testing requirements via the dispensing mechanism 2. The workpiece to be tested is placed on the electrically controlled slide table 32. Two electric clamps 35 slide along the positioning slide groove 33 and the limiting guide groove 34, symmetrically clamping the workpiece. The clamping force is adjusted by the control mechanism to adapt to the workpiece material. The electrically controlled slide table 32 makes precise displacement along the adjusting slide rail 31. Simultaneously, the height sensor 36 monitors the distance between the dispensing head and the workpiece surface in real time and feeds back the data. During the dispensing process, if it is necessary to test the amount of glue injected, the workpiece to be tested can be moved above the weighing analytical balance 42 inside the inspection box 41 to complete the weighing of the glue, and multiple dispensing calibrations can be performed. This utilizes precise... The weighing analysis balance 42, with a precision of 0.1 mg, acquires the glue volume data. The inspection chamber 41 ensures a stable weighing environment through constant temperature and humidity control and the sealed protection of the chamber door 43. After dispensing, if it is necessary to detect the shape and trajectory of the glue dots, the electric lead screw 45 operates under the drive motor, causing the lead screw slide 46 to move horizontally along the mounting frame 44. At the same time, the electric lifting frame 47 adjusts the height of the CCD vision inspection scanner 48. With the 360° omnidirectional illumination provided by the ring supplement light 49, the 12-megapixel CCD vision inspection scanner 48 scans the glue dots on the workpiece surface, captures two-dimensional parameters such as diameter and roundness, and automatically analyzes them through image processing algorithms. Finally, it achieves comprehensive testing of multiple performance indicators of the dispensing machine.
