DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1 To Attachment Figure 6 As shown:

[0025] Embodiment 1: The utility model provides an automatic cleaning device for a taping process test probe in the LED packaging industry, comprising a main body 1, including a fixed rod 101, an air flow regulating valve 102 arranged on the fixed rod 101, a ventilation pipe 103 arranged at the rear end of the air flow regulating valve 102, an air blowing pipe 104 arranged at the front end of the air flow regulating valve 102, and an infrared sensor 105 arranged in the air blowing pipe 104; an anti-blocking mechanism 2, including an anti-blocking component 201 arranged in the air blowing pipe 104, and a reset component 202 arranged between the anti-blocking component 201 and the air blowing pipe 104; and an installation mechanism 3, including an installation component 301 arranged on the fixed rod 101, and an adjustment component 302 arranged on the installation component 301.

[0026] Specifically, the anti-blocking component 201 includes a shaft 2011 arranged in the blowing tube 104, a baffle 2012 arranged on the shaft 2011, and a plurality of reinforcement strips 2013 arranged on the inner side of the baffle 2012. The reinforcement strips 2013 can not only improve the strength of the baffle 2012 and extend its service life, but also guide the airflow when it is opened for cleaning.

[0027] Furthermore, two groups of anti-blocking components 201 are provided. The two groups of anti-blocking components 201 are respectively located on both sides of the infrared sensor 105 , and a guide plate 106 is provided between the infrared sensor 105 and the air blowing pipe 104 .

[0028] Specifically, the reset assembly 202 includes a fixing plate 2023 disposed in the air blowing tube 104 , a rotating disk 2021 disposed at the front end of the shaft 2011 , and a torsion spring 2022 disposed between the fixing plate 2023 and the rotating disk 2021 .

[0029] Furthermore, a threaded rod 2024 is provided on the fixing plate 2023 , and the threaded rod 2024 penetrates the air blowing pipe 104 and is provided with a rotating wheel 2025 , and the threaded rod 2024 is threadedly connected to the air blowing pipe 104 .

[0030] As can be seen from the above, during operation, the device is installed at the working position through the installation mechanism 3, so that the air blowing pipe 104 is facing the test probe, and the infrared sensor 105 will emit infrared guide light to facilitate personnel to accurately locate, and then the device is connected to the external air source pipeline through the ventilation pipe 103, so that the clean air flow can be delivered to the device and blown to the probe through the air blowing pipe 104 to automatically clean the probe. The cleaning cycle can be set according to the operation time and the number of operation products, so that the cleaning can be automatically performed after the cleaning cycle is reached, effectively improving the cleaning frequency and cleanliness of the probe, thereby keeping the product electrical test accurate and stable, reducing product electrical misjudgment, and improving the yield rate;

[0031] The flow rate of the cleaning airflow can be controlled by the airflow regulating valve 102. When the airflow is blown out from the air blowing pipe 104, the thrust of the airflow will push the two baffles 2012 apart. The baffles 2012 will be rotated open by the shaft 2011, and the torsion spring 2022 will be tightened, which will not affect the normal cleaning work of the airflow. When the airflow is stopped after the cleaning work, the torsion spring 2022 will release the elastic potential energy that was previously tightened due to the disappearance of resistance, thereby driving the baffle 2012 to rotate in the initial direction until it returns to the initial closed state. In conjunction with the infrared sensor 105, the air outlet of the air blowing pipe 104 can be shielded and protected, which has an anti-blocking effect. The effect can effectively prevent dust and debris from entering the air blowing pipe 104 when not in use and causing blockage, thereby affecting the subsequent use when cleaning is required again. When the device has been used for a long time and the elastic potential energy of the torsion spring 2022 decreases, the rotating wheel 2025 can be rotated to drive the fixing plate 2023 to rotate together through the threaded rod 2024, and the fixing plate 2023 can be driven to move horizontally through the threaded connection relationship between the threaded rod 2024 and the air blowing pipe 104. The fixing plate 2023 can be controlled to rotate and move toward the center of the air blowing pipe 104, and the torsion spring 2022 can be tightened to normally perform the reset work of the baffle 2012, thereby extending the service life of the device.

[0032] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the mounting assembly 301 includes an elastic clip 3012 arranged on the fixing rod 101, a fastening bolt 3013 arranged on the elastic clip 3012, and a mounting plate 3011 arranged at the bottom of the elastic clip 3012.

[0033] Specifically, the adjustment component 302 includes a handle 3021 disposed on the elastic clip 3012 , a movable groove 3022 disposed in the handle 3021 , and a limit bolt 3023 threadedly disposed on the mounting plate 3011 ; the movable groove 3022 is adapted to the movement trajectory of the limit bolt 3023 .

[0034] As can be seen from the above, when the device is used, the device can be first fixed at the work site by the mounting plate 3011. When the device needs to be disassembled for partial parts replacement and maintenance or mobile storage, the limit bolt 3023 can be rotated and removed from the mounting plate 3011 to separate the elastic clip 3012 from the mounting plate 3011, and then the fastening bolt 3013 is loosened. The elastic clip 3012 will automatically expand by its own elasticity to release the clamping limit force on the fixing rod 101. At this time, the fixing rod 101 can be easily pulled out from the elastic clip 3012, and the device is divided into three parts, which is convenient for personnel to carry out partial parts maintenance or mobile storage.

[0035] After the device is installed at the workplace, the fastening bolt 3013 can be loosened as needed, and then the air blowing pipe 104 can be rotated to make it rotate in the elastic clip 3012 with the fixing rod 101 as the axis, so as to vertically rotate and adjust the direction of the air blowing pipe 104. After the adjustment is completed, the fastening bolt 3013 is rotated to clamp and fix the position of the fixing rod 101 through the elastic clip 3012, and then the limiting bolt 3023 is loosened. At this time, the air blowing pipe 104 is pushed, and it can be horizontally moved on the mounting plate 3011 through the movable groove 3022, or rotated with the limiting bolt 3023 as the axis. Not only can the position of the air blowing pipe 104 be adjusted, but also the direction of the air blowing pipe 104 can be horizontally rotated and adjusted until, under the guidance of the infrared sensor 105, the air blowing pipe 104 is aligned with the probe to be cleaned. The adjustment is convenient, the application range of the device is improved, and it is convenient for personnel to use.
