[0002] In the production process of chip inductors, one of the links is to perform glue dispensing to reinforce the connection between the magnetic core and the magnetic cover and to achieve insulation. After the glue dispensing is completed, the glue dispensing part needs to be dried. In the current glue dispensing and drying integrated equipment, the components are glued by the glue dispensing device, and then the glued components are arranged by the arranging device, and the arranged components are transported to the drying device by the conveying device for drying. Most of the current drying devices adopt a box-type structure. In order to prevent damage to electronic components, most of them use hot air to dry the components, and an external exhaust gas treatment device is connected to the top of the box to treat the exhaust gas generated during the drying process.

DETAILED DESCRIPTION

[0013] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0014] like Figures 1 to 4 As shown, a specific embodiment of the present invention discloses a drying device for post-treatment of electronic component glue dripping, including a housing 100, a support frame 200 installed inside the housing 100, and a hot air blower 300, an exhaust fan 400, a first manifold 500, a second manifold 600, a pushing structure 700, and a plurality of cover structures 800 installed on the support frame 200; the hot air blower 300 provides hot air to the plurality of cover structures 800 through the first manifold 500, and the exhaust fan 400 provides hot air to the plurality of cover structures 800 through the second manifold 600. The gas inside the multiple cover structures 800 is extracted in and out; the pushing structure 700 is used to drive the cover structure 800 to move up and down. When the cover structure moves downward, the bottom is opened; the cover structure moves downward to press against the conveyor belt surface, forming an independent area on the outside of the side-by-side electronic components to achieve targeted hot air drying and exhaust; when the cover structure moves upward, the bottom is closed to prevent the internal airflow from disturbing the airflow inside the shell, and to prevent the gas inside the shell from being discharged from the port; it also reduces the start and stop frequency of the hot air blower and the exhaust fan.

[0015] The above-mentioned drying equipment for post-treatment of electronic components by glue dripping and the use method thereof have a novel structure, including a shell, a support frame installed inside the shell, and a hot air blower, an exhaust fan, a first manifold, a second manifold, a pushing structure, and multiple cover structures installed on the support frame; the hot air blower provides hot air to the multiple cover structures through the first manifold, and the exhaust fan extracts the gas in and out of the multiple cover structures through the second manifold; the pushing structure is used to drive the lifting and lowering activities of the cover structure, and when the cover structure moves downward, the bottom is opened; the cover structure moves downward to abut against the conveyor belt surface, forming an independent area on the outside of the side-by-side electronic components, and the electronic components in this area are subjected to targeted hot air drying and exhaust, which can effectively improve the drying efficiency and quality, and effectively prevent the exhaust gas from being discharged from the source during the drying process; When the cover structure moves upward, the bottom is closed to prevent the internal airflow from disturbing the airflow inside the shell, thereby preventing or reducing the discharge of the gas inside the shell from the port, and further preventing the exhaust gas from being discharged; When the cover structure is in the process of closing at the bottom, the hot air blower and the exhaust fan are still in working condition, maintaining normal heat supply and gas circulation, facilitating the subsequent effective drying of the supply, reducing the start and stop frequency of the hot air blower and the exhaust fan, and preventing damage to the hot air blower and the exhaust fan.

[0016] Furthermore, if Figures 5 to 8 As shown, the cover structure 800 includes a cover body 810 and a baffle 820. The bottom of the cover body is open. The two sides of the cover body 810 are respectively provided with a first clamping cavity 811 and a second clamping cavity 812. The first clamping cavity 811 is connected to a side near the center of the cover body 810 and is provided with a plurality of evenly spaced air outlet holes 813. The second clamping cavity 812 is connected to a side near the center of the cover body 810 and is provided with an air extraction hole 814. The two outer walls of the cover body 810 are respectively connected to a first air delivery pipe 830 and a second air delivery pipe 840. The top of the first air delivery pipe 830 is connected to the first manifold 500 through a first soft The first air delivery pipe 850 is connected, the top end of the second air delivery pipe 840 is connected to the second manifold 600 through the second hose 860, the first manifold 500 is connected to the air outlet of the hot air blower 300, and the second manifold 600 is connected to the air inlet of the exhaust fan 400. The hot air is sent into the first clamping cavity through the hot air blower and sent out through multiple air outlets. The exhaust fan sucks the second clamping cavity to maintain a negative pressure state, and sucks the hot air and the entrained exhaust gas after passing through the surface of the electronic components to prevent the exhaust gas from being discharged. The other ports of the hot air blower and the exhaust fan extend to the outside of the housing; The shape of the baffle 820 is adapted to the internal shape of the cover body 810. The baffle 820 is fixed to the support frame 200 through a plurality of movable vertical rods 821 that pass through the top of the cover body 810. The baffle itself does not move. The pushing structure 700 is used to push the cover body 810 to move vertically, changing the distance between the baffle and the bottom of the cover body. When the cover body moves down to a preset position, the baffle leaves the bottom of the cover body to achieve an opening effect at the bottom of the cover body. The cover body can surround the outside of the electronic component so that the cover body is pressed against the conveyor belt surface to achieve targeted hot air drying and exhaust action; when the cover body moves up to a preset position, the baffle is at the bottom opening position of the cover body, forming a shielding and blocking effect to prevent the internal flowing gas from disturbing the airflow inside the outer shell.

[0017] Furthermore, the air outlet holes are circular hole structures, and the spacing positions of the air outlet holes correspond to the spacing positions of the arranged electronic components, so as to effectively spray hot air and improve the drying effect; the exhaust holes are strip hole structures, so as to perform suction over a larger range and prevent the exhaust gas generated during the glue solidification process from being discharged.

[0018] Furthermore, the pushing structure 700 includes a bracket 710 and at least two electric push rods 720, the electric push rods 720 are installed on the support frame 200, the bracket 710 is located below the support frame 200, the piston rod end of the electric push rod 720 is installed with a push seat 730, and the bracket 710 is installed between the two push seats 730 by bolts; multiple cover bodies 810 are installed at the bottom of the bracket 710; the multiple cover bodies are pushed synchronously, and the synchronous and smooth lifting and lowering are achieved, which also reduces the use of driving components and reduces energy consumption.

[0019] Furthermore, first clamping strips 711 are provided on both sides of the bottom of the bracket 710, and two first clamping seats 815 are correspondingly provided on the top surface of the cover body 810. The first clamping seats 815 are slidably clamped on the first clamping strips 711 and reinforced by bolts. The cooperation of the first clamping strip and the first clamping seat can effectively prevent the cover body from loosening, and the cover body can be further reinforced by bolts. In addition, the cover body is at the bottom of the sliding clamping seat bracket, so it can be clamped first and then moved to the position, which is convenient for actual assembly and use.

[0020] Furthermore, vertical rods 821 are fixedly provided at the four corners of the top surface of the baffle 820 to stably hang and fix the baffle; a plurality of second through holes are correspondingly provided on the top surface of the cover body, and the vertical rods penetrate the top surface of the cover body through the second through holes; Fig. 9 As shown, the support plate of the support frame 200 is provided with a first through hole 210 corresponding to the multiple vertical poles 821. The top of the vertical pole passes through the support plate through the first through hole. Two slots are provided on the top of the vertical pole. The slots are used to hold the retaining springs. The top of the vertical pole is installed on the support plate through the two retaining springs. The overall structure is simple and convenient for disassembly, assembly and fixation of the baffle.

[0021] Furthermore, guide holes 220 are provided on the support plate corresponding to the first air pipe 830 and the second air pipe 840. The first air pipe and the second air pipe pass through the support plate through the guide holes. The first air pipe and the second air pipe slide along the guide holes.

[0022] Furthermore, the housing includes a support frame, and the bottoms of both ends of the support frame are respectively provided with a first open opening and a second open opening, and the first open opening and the second open opening are used to adapt to the installation of a conveyor belt to realize the entry and exit movement of electronic components, complete the automatic and fixed-distance movement effect, and facilitate the accurate alignment of the cover body and the arranged electronic components to achieve the required cover effect; the two sides of the support frame are open, and the outer cover is provided with a cover plate, and a detachable structure is adopted, which is convenient for the processing and production of various structural components, and also convenient for the disassembly, maintenance and replacement of the internal structure, and convenient for use; it should be noted that matching holes are provided on the support frame and the corresponding cover plate, so as to facilitate the external connection of the pipes of the hot air blower and the exhaust fan, especially the external exhaust pipe of the exhaust fan needs to be connected to the exhaust gas treatment equipment to prevent pollution to the outside; in addition, holes for installing the electric control box and wire hole positions are provided to facilitate the overall installation and wiring requirements; like Fig.10 As shown, in the actual use process, a vibration loading tray, a first arranging device, a glue dispensing device, a second arranging device, and a conveying device are required.
