[0027] Refer to Figure 1 , Figure 1 is an axonometric view of the feeding device of the first embodiment. The feeding device of this embodiment includes a frame 210, a loading platform 220, a first feeding component 230, a second feeding component 240, a storage platform 250, and a vibrating disk 260. The loading platform 220 is used to carry stacked PCB boards (i.e., the first material), and a film is padded on one side of the stacked PCB boards in the negative Y-axis direction. Multiple stacks of spaced PCB boards can be placed on the film. The storage platform 250 is used to place stacked humidity cards (i.e., the third material), and the vibrating disk 260 is used to arrange and discharge desiccants (i.e., the second material) one by one. The first feeding component 230 is used to transfer the desiccant from the vibrating disk 260 to the PCB board, and the second feeding component 240 is used to transfer the humidity card to the PCB board. Thus, after the feeding by the feeding device, at least one pack of desiccant and one humidity card are placed beside each stack of PCB boards.

[0028] Reference Figure 1 and Figure 2 , Figure 2 is Figure 1 an exploded view of the load platform 220 in []. The load platform 220 includes a rectangular frame 221, a conveyor belt 222, a first roller 223, a sixth driving device 224, and a second roller 225. The first roller 223 and the second roller 225 are arranged in parallel, and the second roller 225 is located on one side of the first roller 223 in the negative Z-axis direction. One end of the first roller 223 in the positive X-axis direction is rotatably connected to one side edge of the rectangular frame 221, and one end of the first roller 223 in the negative X-axis direction is rotatably connected to the other side edge of the rectangular frame 221. The second roller 225 is the same. The conveyor belt 222 is sleeved on the first roller 223 and the second roller 225, and the first roller 223 and the second roller 225 tension the conveyor belt 222. Thus, a working surface 226 is formed on the upper surface of the conveyor belt 222, and the PCB board is placed on the working surface 226. The sixth driving device 224 is used to drive the conveyor belt 222 to rotate, so as to assist in driving the foam carrying the PCB board onto the working surface 226 (the foam is driven by a separate driving device).

[0029] The sixth driving device 224 includes a first motor 271, a first synchronous pulley 272, a first synchronous belt 273, and a second synchronous pulley 274. The rotating shaft of the first motor 271 is fixedly connected to the input shaft of the reducer (connected by a coupling), and the output shaft of the reducer is fixedly connected to the second synchronous pulley 274 (connected by a key and a set screw). The first synchronous pulley 272 is fixedly connected to one end of the first roller 223 in the positive X-axis direction (connected by a key and a set screw), the first synchronous belt 273 is sleeved on the second synchronous pulley 274 and the first synchronous pulley 272, and the teeth on the inner ring surface of the first synchronous belt 273 mesh with the teeth on the outer circumferential surface of the second synchronous pulley 274 and the teeth on the outer circumferential surface of the first synchronous pulley 272. Thus, when the first motor 271 is powered on, the rotating shaft of the first motor 271 drives the first roller 223 to rotate through the second synchronous pulley 274, the first synchronous belt 273, and the first synchronous pulley 272 in sequence, and finally drives the conveyor belt 222 to rotate.

[0030] Reference Figure 1 and Figure 3 , Figure 3 is Figure 1Exploded view of the intermediate storage platform 250. The storage platform 250 is arranged at one end of the frame 210 in the positive X-axis direction. The storage platform 250 includes a support base 251, a fifth driving device, and a silo 253. The fifth driving device is a rotary cylinder 252. A plurality of limiting bars 255 extending in the positive Y-axis direction are arranged on the silo 253. The plurality of limiting bars 255 enclose two storage positions 254, and humidity cards stacked can be placed in the storage positions 254. The silo 253 is fixedly locked to the turntable of the rotary cylinder 252 by screws, and the cylinder body of the rotary cylinder 252 is fixed to the frame 210 through the support base 251. After the rotary cylinder 252 is ventilated, the silo 253 will rotate in the XZ plane. After the silo 253 rotates 180°, the two storage positions 254 will exchange positions. Thus, when the humidity cards in one storage position 254 are used up, by rotating the silo 253, the other storage position 254 full of humidity cards can be switched to the picking position, and the emptied storage position 254 is replenished with materials. Thus, the picking process of the humidity cards is not interrupted, and the humidity cards can be continuously loaded.

[0031] In another embodiment, the fifth driving device can also use a servo motor, and the servo motor can also achieve the position switching of the two storage positions 254.

[0032] In another embodiment, the fifth driving device can also be a linear motor or a common cylinder, and the silo 253 realizes the position switching of the two storage positions 254 by translating along the Z-axis direction. In addition, the number of the storage positions 254 can also be three, four, or five.

[0033] Refer to Figure 1 、 Figure 4 and Figure 5 , Figure 4 is Figure 1 the exploded view of the first driving device in Figure 5 is Figure 1 the exploded view of the second driving device, the third driving device, and the first picking head 233 in

[0034] Reference Figure 4 Specifically, the first driving device includes a first driving assembly 231, a second driving assembly 232 and a mounting plate 234. The second driving assembly 232 is arranged at the output end of the first driving assembly 231, the mounting plate 234 is fixed at the output end of the second driving assembly 232, and the first material taking head 233 is arranged on the mounting plate 234. The first driving assembly 231 is used to drive the first material taking head 233 to move in the Z-axis direction, and the second driving assembly 232 is used to drive the first material taking head 233 to move in the X-axis direction.

[0035] The first driving assembly 231 includes a first slide table 281, a third synchronous pulley 282, a second synchronous belt 283, a fourth synchronous pulley 284, a first synchronous pulley assembly 285, a second motor 286, a first support rod 287, a third synchronous belt 288 and a sliding assembly 289. The first support rod 287 is an aluminum profile, and the length direction of the first support rod 287 is arranged along the Z-axis direction, and a through channel is arranged in the first support rod 287 along the Z-axis direction. There are two first synchronous pulley assemblies 285, one first synchronous pulley assembly 285 is arranged at one end of the first support rod 287 in the positive Z-axis direction, and the other first synchronous pulley assembly 285 is arranged at one end of the first support rod 287 in the negative Z-axis direction. The first synchronous pulley assembly 285 includes a fifth synchronous pulley and a first housing. The fifth synchronous pulley is located in the first housing, the fifth synchronous pulley is rotatably connected to the first housing, and the first housing is locked to the first support rod 287 by screws. The third synchronous belt 288 is sleeved on the two fifth synchronous pulleys. The lower half of the third synchronous belt 288 is located in the channel of the first support rod 287, and the upper half of the third synchronous belt 288 is located above the first support rod 287. The first slide table 281 is locked and fixed on the third synchronous belt 288 through fasteners.

[0036] The rotating shaft of the second motor 286 is fixedly connected to the third synchronous pulley 282 (fixedly connected through a expansion sleeve), and the fourth synchronous pulley 284 is fixedly connected to the fifth synchronous pulley at one end of the first support rod 287 in the positive Z-axis direction (fixedly connected through a expansion sleeve). The second synchronous belt 283 is sleeved on the third synchronous pulley 282 and the fourth synchronous pulley 284. Thus, when the second motor 286 is powered on, the first slide table 281 will move in the Z-axis direction, that is, the first slide table 281 is the output end of the first driving assembly 231.

[0037] To provide good support for the second driving assembly 232 and guide the movement of the second driving assembly 232 at the same time, a sliding assembly 289 is provided. The sliding assembly 289 includes a slide rail and a slider. The slide rail and the slider are slidably connected. The length direction of the slide rail is arranged along the Z-axis direction. Thus, the slider will slide along the Z-axis direction on the slide rail. The slide rail is locked and fixed on the frame 210 by screws. Both the first slide table 281 and the slider are connected to the second driving assembly 232.

[0038] The structure of the second driving component 232 is similar to that of the first driving component 231. The difference between the second driving component 232 and the first driving component 231 is that the second driving component 232 does not include the sliding component 289. Specifically, the second driving component 232 includes a sixth synchronous pulley, a fourth synchronous belt, a seventh synchronous pulley, a third motor, a second synchronous pulley assembly, a fifth synchronous belt, and a second sliding table. The length direction of the second support rod 291 is arranged along the X-axis direction, and a through channel is arranged along the X-axis direction inside the second support rod 291. The second support rod 291 is fixedly connected to the first sliding table 281 and the slider respectively (locked by screws).

[0039] There are two second synchronous pulley assemblies. One second synchronous pulley assembly is arranged at one end of the second support rod 291 in the positive X-axis direction, and the other second synchronous pulley assembly is arranged at one end of the second support rod 291 in the negative X-axis direction. The second synchronous pulley assembly includes an eighth synchronous pulley and a second housing. The eighth synchronous pulley is rotatably connected to the second housing. The fifth synchronous belt is sleeved on the two eighth synchronous pulleys. The lower half of the fifth synchronous belt is located in the channel of the second support rod 291, and the upper half of the fifth synchronous belt is located above the second support rod 291. The second sliding table is fixed on the fifth synchronous belt (locked by fasteners). The third motor drives the eighth synchronous pulley to rotate through the sixth synchronous pulley, the fourth synchronous belt, and the seventh synchronous pulley, and then drives the second sliding table to move along the X-axis direction.

[0040] The mounting plate 234 is fixedly locked on the second sliding table by screws.

[0041] In another embodiment, both the first driving component 231 and the second driving component 232 can be replaced by a combination of a motor, a lead screw, and a nut.

[0042] Referring to Figure 5 , the second driving device includes a first cylinder 292, a guide rod 293, a first mounting block 294, a second cylinder 295, and a second mounting block 299. The first cylinder body of the first cylinder 292 is fixedly locked on the mounting plate 234 by screws. The first mounting block 294 is fixed on the first piston rod of the first cylinder 292 (fixed by a nut). The second cylinder body of the second cylinder 295 is fixedly locked on the first mounting block 294 by screws. The second mounting block 299 is fixed on the second piston rod of the second cylinder 295 (fixed by a nut). And the first material taking head 233 is arranged on the second mounting block 299. Thus, whether the first cylinder 292 acts or the second cylinder 295 acts, the first material taking head 233 can be made to move along the Y-axis direction.

[0043] In addition, the stroke of the first material taking head 233 is the sum of the strokes of the first cylinder 292 and the second cylinder 295, and the stroke of the first cylinder 292 is much larger than that of the second cylinder 295 (about several times to more than a dozen times). Thus, when the first material taking head 233 approaches the vibrating bowl 260 or the working surface 226, the first cylinder 292 can act first. When the first material taking head 233 is close to the vibrating bowl 260 or the working surface 226, the second cylinder 295 acts to complete the material taking action. By designing the stroke of the first material taking head 233 as the sum of a large stroke and a small stroke, the displacement accuracy of the first material taking head 233 can be improved. That is, the final stroke of the first material taking head 233 is completed by the second cylinder 295. Since the stroke of the second cylinder 295 is small, large errors are not likely to occur.

[0044] In another embodiment, the second driving device can also be replaced by a combination of a motor, a lead screw, and a nut.

[0045] The third driving device includes a positioning block 297 and a swing cylinder 298. The cylinder body of the swing cylinder 298 is locked and fixed to the second mounting block 299 by screws, and the positioning block 297 is locked and fixed to the cylinder body of the swing cylinder 298 by screws. The swing cylinder 298 includes a swing rod 296. One end of the swing rod 296 is fixedly connected to the rotating shaft of the swing cylinder 298, and a first material taking head 233 is fixed to the other end of the swing rod 296. The first material taking head 233 is a first suction nozzle. After the first suction nozzle is connected to a negative pressure air source (such as a vacuum pump), it can suck the desiccant.

[0046] When the first suction nozzle sucks the material from the vibrating bowl 260, the first suction nozzle is in a vertical state. Under the action of the first driving device and the second driving device, when the first suction nozzle moves to near the stacked PCB boards, the swing cylinder 298 drives the swing rod 296 to rotate until the swing rod 296 abuts against the positioning block 297. At this time, the negative pressure of the first suction nozzle disappears, and the desiccant leans against the stacked PCB boards. After subsequent vacuum pumping, the desiccant will be closely attached to the PCB boards, thereby continuously absorbing the water vapor near the PCB boards.

[0047] After the desiccant is placed in place, the swing cylinder 298 rotates again, the swing rod 296 moves away from the positioning block 297, and the first suction nozzle returns to the vertical state, so as to perform the next material taking.

[0048] Refer to Figure 1 、 Figure 4 and Figure 6, the second material discharging assembly 240 includes a first driving device, a fourth driving device, and a second material taking head 241. The fourth driving device is disposed on the output end of the first driving device (i.e., the mounting plate 234), and the second material taking head 241 is disposed on the output end of the fourth driving device. The first driving device is used to drive the second material taking head 241 to move along the X-axis direction and the Z-axis direction, so that the second material taking head 241 reaches any position on the working surface 226. The fourth driving device is used to drive the second material taking head 241 to move along the Y-axis direction, so that the second material taking head 241 can approach the storage platform 250 to pick up the humidity card, and so that the second material taking head 241 can approach the working surface 226 to place the humidity card on the PCB board. The second material taking head 241 is a second suction nozzle.

[0049] The second material discharging assembly 240 shares the first driving device with the first material discharging assembly 230, thereby saving material costs, simplifying the structure of the material discharging device, reducing the space occupied by the material discharging device, and improving the competitiveness of the material discharging device.

[0050] Refer to Figure 6 , the fourth driving device includes a mounting seat 242, a linear bearing 243, a smooth rod 244, a connecting plate 245, a nut 246, a lead screw 247, a fourth motor 248, a rolling bearing 249, a ninth synchronous pulley, a tenth synchronous pulley, and a sixth synchronous belt. The mounting seat 242 is locked and fixed to the mounting plate 234 by screws. There are two rolling bearings 249. One end of the lead screw 247 in the negative Y-axis direction is rotatably connected to the mounting seat 242 through the two rolling bearings 249. The rotating shaft of the fourth motor 248 is connected to one end of the lead screw 247 in the negative Y-axis direction through the ninth synchronous pulley, the tenth synchronous pulley, and the sixth synchronous belt. The nut 246 is in threaded engagement with the lead screw 247. The smooth rod 244 is slidably connected to the mounting seat 242 through the linear bearing 243. One end of the smooth rod 244 in the positive Y-axis direction is fixedly connected to the nut 246 through the connecting plate 245. The second suction nozzle is fixed to one end of the smooth rod 244 in the negative Y-axis direction. Thus, after the fourth motor 248 is powered on, the smooth rod 244 will drive the second suction nozzle to move along the Y-axis.

[0051] In another embodiment, the fourth driving device can also be a rotary cylinder or a linear motor.

[0052] In summary, initially, under the action of the second driving device, the first suction nozzle moves along the negative Y-axis direction to pick up the desiccant from the vibrating disk 260; then, under the action of the second driving device, it moves along the positive Y-axis direction to avoid colliding with the PCB board or other objects during the subsequent movement. At the same time, under the action of the fourth driving device, the second suction nozzle moves along the negative Y-axis direction to pick up the humidity card from the storage position 254; then, under the action of the fourth driving device, it moves along the positive Y-axis direction to avoid colliding with the PCB board or other objects during the subsequent movement.

[0053] Then, under the action of the first driving device, the first suction nozzle and the second suction nozzle approach a group of PCB boards. Then, under the action of the second driving device, the first suction nozzle moves in the negative Y-axis direction and approaches the working surface 226. After the stroke of the second driving device is completed, the first suction nozzle tilts under the action of the third driving device, and leans the desiccant against the PCB board. After the desiccant is placed, the first suction nozzle returns to the vertical state under the action of the third driving device and moves in the positive Y-axis direction under the action of the second driving device. While the second suction nozzle moves in the negative Y-axis direction under the action of the fourth driving device and places the humidity card on the PCB board, and then moves in the positive Y-axis direction under the action of the fourth driving device.

[0054] Finally, under the action of the first driving device, the first suction nozzle and the second suction nozzle return to the material-taking position. Thus, a discharging action is completed. Then, the discharging action is performed on each group of PCB boards on the working surface 226.

[0055] The present invention also relates to a packaging device, which includes the above-mentioned discharging device. By using the above-mentioned discharging device, the desiccant can be closely attached to the PCB board, and it is not easy to have the problem of the desiccant separating from the PCB board, ensuring that the desiccant can play its normal role, preventing the PCB board from being eroded by water vapor, and ensuring the packaging effect of the packaging equipment.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
