[0002] The electronic optical adhesive placement machine is a device specially used for mounting electronic optical adhesive. It has the integrated function of dispensing and mounting, and can perform dispensing and mounting operations at the same time, avoiding the glue solidification problem that may occur when all the glue is dispensed first and then moved to the mounting station for mounting, thereby ensuring the viscosity of the components and reducing the displacement of components during tinning.

[0003] In the prior art, such as the Chinese patent number: CN216960365U, an electronic optical glue placement machine is disclosed, which relates to the field of electronic technology. Since the current placement machines are all assembly line work, first all the circuit boards are glued, and then all the glue is moved to the placement station for placement. This will encounter the situation of glue solidification, insufficient viscosity for components, and the problem of displacement when the components are tinned. Now the following scheme is proposed, including a box body, the bottom inner wall of the box body is fixed with two material racks, the bottom inner wall of the box body is fixed with a rodless cylinder 1, and the slider of the rodless cylinder 1 is fixed with two placement boxes, the inner wall of the placement box is fixed with a spring, and the inner sleeve of the placement box is provided with an inner plate, the inner plate is fixedly connected with the spring, the top of the inner plate is fixed with a hook, and the top inner wall of the box body is fixed with a rodless cylinder 2. The utility model integrates the glue dispensing and patching, accelerates the solidification of the glue after patching, avoids the phenomenon of displacement, improves the patching speed, and improves the production efficiency.

[0004] However, in the prior art, it is very important for the electronic optical adhesive placement machine used to stick electronic components on the circuit board to accelerate the solidification of the glue after placement. However, when the electronic components are attached to the glue, due to the different thickness of the glue, it will cause uneven pasting, so pressing is required.

[0037] In this embodiment, when in use, the state of the compression airbag 402 can be changed by inhaling and inflating, and the air pump 406 is started. When inhaling, the second solenoid valve 410 needs to be closed and the first solenoid valve 407 needs to be opened.

[0039] In this embodiment, when in use, the support column 106 supports the operating table 101 to a height that is convenient for the staff to operate. By starting the servo motor 309, the output shaft thereof rotates, thereby driving the I-shaped gear 310 to rotate. Under the meshing action of the I-shaped gear 310 and the passive gear 308, the two rotating drums 318 connected to the passive gear 308 rotate simultaneously outside the reinforcing rod 316. Since the inner walls at both ends of the conveyor belt 302 are movably connected to the rotating drum 318, the rotating drum 318 can make the conveyor belt 302 run at the same time when it rotates. By feeding the electronic components 206 into the feeding box 304, when feeding, the electronic components 206 can be placed on the inclined surface of the feeding box 304 so that it slides onto the conveyor belt 302 by itself, or can be directly placed on the conveyor belt 302 at the discharge port of the feeding box 304. At the same time, under the connection of the connecting belt 311, the rotating wheel 315 will follow the I-shaped gear 3 10 rotates, thereby driving the active bevel gear 314 to rotate. Since the active bevel gear 314 is engaged with the driven bevel gear 107, it will drive the driven bevel gear 107 and the threaded rod 105 to rotate, wherein the threaded rod 105 is clamped and installed inside the two limit clamps 104, and can rotate but will not disengage. The support slide plate 201 slides along the slide rail 102, so that the support slide plate 201 can slide outward from the bottom of the support plate 301.

[0040] Embodiment three: Figure 1-12As shown, a patch component 2 is arranged on the top of the operating table 101, and the patch component 2 includes a supporting slide 201, a circuit board 204 is placed on the top of the supporting slide 201, two patch areas 205 are provided on the top of the circuit board 204, and a plurality of electronic components 206 are placed inside the two patch areas 205, a positioning plate 207 is placed on the top of the circuit board 204, a card board 209 is fixedly connected to one side of the positioning plate 207, a limiting fork 210 is fixedly connected to one side of the supporting slide 201, and the position of the limiting fork 210 matches the card board 209, and a moving component 5 is fixedly connected to the bottom of the operating table 101, and the moving component 5 includes a mounting frame 501, and a forward and reverse motor 502 is arranged on the outer surface of the mounting frame 501, and a reinforcing block 503 is fixedly connected to the output shaft of the forward and reverse motor 502, and an electric push rod 504 is arranged on the top of the reinforcing block 503, and a card frame 505 is fixedly connected to the top of the electric push rod 504, and the inner wall of the card frame 505 matches the outer surface of the card board 209.

[0041] In this embodiment, when in use, after the pasting and pressing operation of the electronic components 206 on the circuit board 204 is completed, the positioning plate 207 needs to be taken out, and then the circuit board 204 is taken out. When the supporting slide plate 201 slides along the slide rail 102, the card plate 209 is inserted into the card frame 505. When taking it out, the electric push rod 504 is started to extend it, thereby driving the card frame 505 to move upward, and then driving the card plate 209 and the positioning plate 207 to move upward. When the positioning plate 207 and the circuit board 204 are separated, After separation, the forward and reverse motor 502 is started to rotate its output shaft, thereby rotating the positioning plate 207 to one side. After the circuit board 204 is taken out and replaced, the positioning plate 207 is rotated back to its original position and lowered and placed on the new circuit board 204. The clamping plate 209 is clamped on the limiting fork 210, so that the position of the positioning plate 207 and the circuit board 204 can be completely aligned. In addition, the positioning area 208 can be used to position the electronic component 206 to prevent the position of the electronic component 206 from shifting.

[0042] The method of use and working principle of this device: When in use, the support column 106 supports the operating table 101 to a height that is convenient for the staff to operate. By starting the servo motor 309, the output shaft is rotated, thereby driving the I-shaped gear 310 to rotate. Under the meshing action of the I-shaped gear 310 and the passive gear 308, the two rotating drums 318 connected to the passive gear 308 are simultaneously rotated outside the reinforcement rod 316. Since the inner walls at both ends of the conveyor belt 302 are movably connected to the rotating drum 318, the rotating drum 318 will cause the conveyor belt 302 to run at the same time when it rotates. By dropping the electronic components 206 into the feeding box 304, when dropping, the electronic components 206 can be placed on the inclined surface of the feeding box 304 so that it slides down by itself. The conveyor belt 302 can also be placed directly on the conveyor belt 302 at the discharge port of the feeding box 304. At the same time, under the connection of the connecting belt 311, the rotating wheel 315 will rotate with the I-shaped gear 310, thereby driving the active bevel gear 314 to rotate. Since the active bevel gear 314 is engaged with the driven bevel gear 107, it will drive the driven bevel gear 107 and the threaded rod 105 to rotate, wherein the threaded rod 105 is clamped and installed inside the two limit clamps 104, and can rotate but will not disengage, and the support slide plate 201 slides along the slide rail 102, so that the support slide plate 201 can slide outward from the bottom of the support plate 301, and the linkage structures match each other, and the operation realized is that when the support slide plate 201 slides outward, the conveyor belt The electronic components 206 on the surface of 302 fall onto the circuit board 204, that is, they are located in each positioning area 208. The moving speeds of the conveyor belt 302 and the supporting slide 201 are matched, so that the gluing positioning of multiple electronic components 206 can be completed at the same time, wherein the circuit board 204 is placed on the supporting slide 201 after the adhesive part of its surface is coated with glue. When in use, the state of the pressing airbag 402 can be changed by suction and inflation. The air pump 406 is started. When suctioning, the second solenoid valve 410 needs to be closed and the first solenoid valve 407 opened. Then, the gas inside the two pressing airbags 402 will be transported to the connecting pipe 408 through the air pipe 403. At this time, the pressing airbag 402 is in a stored state. When inflated, When the second solenoid valve 410 is opened and the first solenoid valve 407 is closed, the air pump 406 pressurizes the gas to allow the gas to enter the ventilation pipe 409, and then enters the two air pipes 403 through one section of the connecting pipe 408, and enters the two hollow cavities 401 through the delivery of the two air cylinders 404 and the fixing pipe 405. The air pressure inside the hollow cavity 401 increases, causing the two pressing airbags 402 to swell. The positions of the two pressing airbags 402 correspond to the positions of the circuit boards 204 that have been placed and glued. When the pressing airbags 402 swell, they will contact the electronic components 206 pasted on the surface of the circuit boards 204, thereby generating a pressing effect. After the pressing operation is completed, the two output shafts of the bidirectional synchronous motor 413 are rotated by starting the bidirectional synchronous motor 413.The two screw rods 414 are thereby driven to rotate simultaneously, and the two reinforcing plates 416 are moved outward simultaneously during the rotation. Since the bending rod 411 is fixed to the reinforcing plate 416, the reinforcing plate 416 drives the connected bending rod 411 to move outward simultaneously, thereby moving the two hollow cavities 401 to the upper sides of the operating table 101 to avoid obstruction to the removal of the circuit board 204. The gas delivery pipe 403, the connecting pipe 408, and the ventilation pipe 409 are made of soft materials and do not affect the movement of the two hollow cavities 401. When in use, after the pasting and pressing operation of the electronic components 206 on the circuit board 204 is completed, the positioning plate 207 needs to be taken out, and then the circuit board 204 is taken out. When the supporting slide plate 201 slides along the slide rail 102, the card The plate 209 is inserted into the card frame 505. When it is taken out, the electric push rod 504 is started to extend it, thereby driving the card frame 505 to move upward, and then driving the card plate 209 and the positioning plate 207 to move upward. After the positioning plate 207 and the circuit board 204 are separated, the forward and reverse motor 502 is started to rotate its output shaft, thereby rotating the positioning plate 207 to one side. After the circuit board 204 is taken out and replaced, the positioning plate 207 is rotated back to its original position and lowered to be placed on the new circuit board 204. The card plate 209 is stuck on the limit fork 210, so that the position between the positioning plate 207 and the circuit board 204 can be completely corresponding. In addition, the electronic components 206 can be positioned through the positioning area 208 to prevent the position of the electronic components 206 from being offset.
