Description

Technical Field

[0001] This invention relates to the field of precision mechanical equipment, specifically a multi-nozzle array module. Background Technology

[0002] SMT (Surface Mount Technology) pick-and-place machines are commonly used in the electronics and semiconductor testing industries to accurately place components onto PCB pads using nozzles. In traditional SMT pick-and-place machines, each nozzle typically requires its own independent pneumatic line for precise control, and additional auxiliary structures are added to facilitate the management of these complex lines. This limits the space available for effectively assembling the nozzles, resulting in a limited number of nozzles and consequently, low placement efficiency, significantly restricting the machine's production capacity. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a multi-nozzle array module.

[0004] The technical solution of this invention is as follows: A multi-nozzle array module includes an upper module and a lower module, which are detachably connected. The lower module includes an air passage plate and a nozzle module, with the nozzle module located below the air passage plate. Solenoid valve assemblies are provided on both sides of the upper module corresponding to the air passage adapter plates on both sides of the air passage plate. The air passage plate has multiple vertical holes arranged in an array, each vertical hole corresponding to an air passage inside the air passage plate. One end of the air passage communicates with the vertical hole, and the other end communicates with the nozzle module.

[0005] Furthermore, the upper module has multiple symmetrically distributed hook seats on one side and a buckle on the other side. The lower module has a suspension support that matches the hook seats and a locking seat that matches the buckle. The upper module has a quick-release mechanism, and the lower module has a cam that matches the quick-release mechanism.

[0006] Furthermore, the quick-release mechanism includes a tension hook and a handle. Tension hooks are provided on both sides of the upper module. One end of the tension hook engages with the cam, and the other end is provided with a handle. The end of the tension hook near the cam is rotatably connected to the upper module.

[0007] Furthermore, the upper module includes a main control PCB board and a U-shaped board. The main control PCB board is located on one side of the U-shaped board, and solenoid valve assemblies are located on both sides of the main control PCB board on the U-shaped board.

[0008] Furthermore, a fixing plate is provided on the U-shaped plate, and the main control PCB board is fixedly connected to the fixing plate. A protective cover is provided on the side of the main control PCB board away from the fixing plate.

[0009] Furthermore, the solenoid valve assembly includes a signal board and an airflow manifold. The signal board is located on one side of the airflow manifold, and multiple solenoid valve bodies are arranged in an array on the side of the airflow circuit board away from the signal board. The solenoid valve bodies are connected to the airflow manifold.

[0010] Furthermore, both ends of the air manifold are equipped with connectors that connect to external air pipes, and the bottom surface of the air manifold near the lower module is equipped with multiple air holes that cooperate with the air transition plate.

[0011] Furthermore, a fixed seat is provided on the outer periphery of the lower module, and the air passage plate and air passage adapter plate are fixedly connected to the fixed seat.

[0012] Furthermore, the nozzle module includes a mounting bracket and nozzle assemblies. The mounting bracket has multiple nozzle assemblies, each comprising a mounting block and individual nozzle units. The bottom of the mounting block has multiple individual nozzle units, and the top of the mounting block has a circular hole corresponding to each nozzle unit, through which the nozzle unit communicates with the air passage.

[0013] Furthermore, a detection PCB board is provided on the side of the split mounting block closest to the nozzle unit.

[0014] Compared with the prior art, the advantages of the present invention are: the upper module and the lower module cooperate to form a highly integrated air supply structure, the air circuit board simplifies the structure of transporting gas, and does not require too many pipeline structures, thereby saving space to assemble more nozzle units and effectively improving the working efficiency of the equipment.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] The specific embodiments of the present invention will now be described in conjunction with the accompanying drawings:

[0028] like Figures 1-4 As shown, a multi-nozzle array module includes an upper module 1 and a lower module 2, which are detachably connected. The upper module 1 has multiple symmetrically distributed hook seats 121 on one side and a buckle 122 on the other side. The lower module 2 has a suspension support 212 that engages with the hook seats 121 and a locking seat 213 that engages with the buckle 122. The engagement of the hook seats 121 with the suspension support 212 and the engagement of the buckle 122 with the locking seat 213 initially fixes the upper module 1 and lower module 2 in their relative positions. The upper module 1 has a quick-release mechanism, and the lower module 2 has a cam 217 that engages with the quick-release mechanism.

[0029] The quick-release mechanism includes a tension hook 123 and a handle 124. Tension hooks 123 are provided on both sides of the upper module 1. One end of the tension hook 123 engages with a cam 217, and the other end is provided with a handle 124. The end of the tension hook 123 near the cam 217 is rotatably connected to the upper module 1. When assembling the upper module 1 and the lower module 2, the handle 124 is operated to rotate the tension hook 123 relative to the upper module 1, engaging with the cam 217, thereby ensuring a tight fit between the upper module 1 and the lower module 2. During disassembly, the handle 124 is operated to rotate the tension hook 123 in the opposite direction, disengaging the tension hook 123 from the cam 217, facilitating the separation of the upper module 1 and the lower module 2.

[0030] The upper module 1 includes a main control PCB board 13 and a U-shaped plate 12. The main control PCB board 13 is located on one side of the U-shaped plate 12, and solenoid valve assemblies 11 are located on both sides of the main control PCB board 13. A fixing plate 131 is provided on the U-shaped plate 12, and the main control PCB board 13 is fixedly connected to the fixing plate 131. A protective cover 132 is provided on the side of the main control PCB board 13 away from the fixing plate 131. The solenoid valve assembly 11 includes a signal board 111 and a gas path manifold 113. The signal board 111 is located on one side of the gas path manifold 113, and multiple solenoid valve bodies 112 arranged in an array are located on the side of the gas path manifold 113 away from the signal board 111. The solenoid valve bodies 112 are connected to the gas path manifold 113. Both ends of the air manifold 113 are equipped with connectors 1131 that connect to external air pipes. The bottom surface of the air manifold 113 near the lower module 2 has multiple air holes 1132 that mate with the air adapter plate 214. The main control PCB board 13 transmits control signals to the solenoid valve body 112 via the signal board 111, thereby controlling the up-and-down movement of the suction nozzle unit 2222 and the material handling operations. The main control PCB board 13 can enable multiple or a single suction nozzle unit 2222 to operate at a specified location.

[0031] like Figures 5-9 As shown, the lower module 2 includes an air passage plate 21 and a nozzle module 22, with the nozzle module 22 located below the air passage plate 21. The upper module 1 has solenoid valve assemblies 11 positioned on both sides of the air passage adapter plates 214 corresponding to the air passage plate 21. A fixing seat 211 is located on the outer periphery of the lower module 2, and both the air passage plate 21 and the air passage adapter plates 214 are fixedly connected to the fixing seat 211. The nozzle module 22 has multiple detachable nozzle assembly 222, each with multiple individual nozzle units 2222. The nozzle module 22 increases the assembly density of the individual nozzle units 2222, allowing for an increase in the number of individual nozzle units 2222 within a limited area.

[0032] The airflow board 21 has multiple vertical holes 215 arranged in an array, each corresponding to an air passage 216 inside the airflow board 21. One end of the air passage 216 communicates with the vertical hole 215, and the other end communicates with the nozzle module 22. The airflow board 21 simplifies the transport gas path structure, eliminating the need for complex pipelines and auxiliary structures, improving the overall integration of the equipment, and saving space to accommodate a larger number of nozzle units 2222. The nozzle module 22 includes a mounting bracket 221 and nozzle assembly 222. The mounting bracket 221 has multiple nozzle assemblies 222, each nozzle assembly 222 including a separate mounting block 2221 and a nozzle unit 2222. The bottom of the split mounting block 2221 is provided with multiple suction nozzle units 2222. The top of the split mounting block 2221 is provided with a circular hole 2224 corresponding to the suction nozzle unit 2222, and the suction nozzle unit 2222 is connected to the air passage 216 through the circular hole 2224. A detection PCB board 2223 is provided on the side of the split mounting block 2221 near the suction nozzle unit 2222. The detection PCB board 2223 is equipped with a vacuum sensor and a position sensor, which can detect in real time whether the suction nozzle module 22 has reached the specified position and whether the vacuum value meets the standard. The detection PCB board 2223 will promptly transmit error signals to the main control PCB board 13, thereby achieving the function of real-time monitoring.
