[0002] The placement machine is a core equipment on the production line of the SMT industry. It is mainly used to assemble electronic components onto circuit boards. The placement machine is a product of the combination of computer control technology and electromechanical optics. It is a precision working robot. It gives full play to the high-tech achievements of modern precision machinery, mechatronics, optoelectronics, and computer control technology to achieve high-speed, high-precision, and intelligent electronic assembly manufacturing equipment. It can quickly and accurately place various electronic components on the specified pad position on the circuit board through functions such as picking, displacement, alignment, and placement. The placement machine is generally located behind the solder paste printer of the entire SMT production line.

[0003] During the use of the placement machine nozzle, solder paste, dust and other dirt can easily clog the nozzle head, which will reduce the nozzle placement accuracy. Before and after the use of the nozzle, workers are usually required to use simple observation equipment such as magnifying glasses to observe whether there is solder paste, dust and other dirt inside the nozzle head and through holes, and clean the above dirt in time so that the nozzle can continue to be used. However, the existing semi-automatic cleaning and observation equipment has low cleaning efficiency and is difficult to align with the light for observation. During the operation process, the operator is required to observe the picture on the display and rely on the operator's experience to judge the quality of the nozzle, which has great limitations.

[0004] Therefore, how to design a nozzle head, through hole and reflector detection device for a placement machine that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0019] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0020] See also Figure 1-3 The device shown includes an observation cleaning device 1 and a storage platform 2 disposed directly below the observation cleaning device 1;

[0021] The observation and cleaning device 1 includes a frame 14, an X-axis assembly 11, a Y-axis assembly 12 and a cleaning observation assembly 13; the X-axis assemblies 11 are arranged on both sides of the frame 14 in parallel; the Y-axis assembly 12 is movably connected above the X-axis assembly 11, spans the X-axis assembly 11 and is arranged perpendicular to the X-axis assembly 11; the cleaning observation assembly 13 is installed on the Y-axis assembly 12;

[0022] The cleaning observation component 13 includes a base 131 movably connected to the Y-axis component 12, an observation cleaning machine 132 arranged on one side of the base 131, and a hydraulic telescopic machine 133 fixed between the base 131 and the observation cleaning machine 132; the observation cleaning machine 132 includes a casing 1321, a rotating shaft 1322, a lighting strip 1323, and a plurality of cameras 1324; the rotating shaft 1322 is rotatably arranged in the casing 1321, one end of the rotating shaft 1322 extends downward to the outside of the casing 1321 and a shell 1325 is fixedly sleeved at the end, and the other end extends upward and a driving motor 1326 is fixedly connected to the end, and a plurality of pairs of fan-shaped cleaning brushes 1327 are symmetrically arranged outside the casing 1325; a plurality of cameras 1324 are circumferentially arranged at the bottom of the casing 1321, and the lighting strip 1323 is also circumferentially arranged at the bottom of the casing 1321. The diameter of the rotating shaft 1322 can be adjusted according to the inner diameter of the nozzle head,

[0023] A power supply 1328 is disposed in the housing 1321 , and the lighting strip 1323 and the plurality of cameras 1324 are respectively connected to the power supply 1328 .

[0024] The distance from the camera 1324 to the center of the circle is greater than the radius of the fan-shaped cleaning brush 1327, and the distance from the lighting strip 1323 to the center of the circle is greater than the distance from the camera 1324 to the center of the circle.

[0025] Furthermore, both the X-axis assembly 11 and the Y-axis assembly 12 are linear modules.

[0026] Furthermore, both ends of the Y-axis assembly 12 are slidably connected to the X-axis assembly 11 .

[0027] The working principle is roughly as follows:

[0028] When the nozzle head that needs to be cleaned is placed on the storage machine 2, the X-axis component 11 and the Y-axis component 12 are controlled by the corresponding control circuit to drive the observation cleaning device 1 to move until it moves to the top of the nozzle head, and the bottom of the rotating shaft 1322 of the observation cleaning machine 132 is extended into the nozzle head by the hydraulic telescopic machine 133. At this time, the lighting strip 1323 lights up, and the camera 1324 performs visual recognition to visually identify the contaminants in the nozzle head. The rotating shaft 1322 drives the outer shell 1325 to rotate, and the fan-shaped cleaning brush 1327 outside the outer shell 1325 cleans the inner wall of the nozzle head. During the cleaning process, the camera 1324 continues to perform visual recognition until no contaminants are detected, and the rotating shaft 1322 stops rotating to achieve the cleaning of the inner wall of the nozzle head.
