[0051] Reference Figure 1 and Figure 2 , Figure 1 is an axonometric view of the PCB packaging device of the first embodiment, Figure 2 yes Figure 1Front view of the PCB packaging equipment in the embodiment. The PCB packaging equipment of this embodiment includes a loading device 100, a discharging device 200, a packaging device 300, a cutting device 400 and a frame 500. The loading device 100, the discharging device 200, the packaging device 300 and the cutting device 400 are arranged in sequence from left to right. The loading device 100 can realize the loading of the first material (i.e., PCB) and the loading of the first film tape (such as foam) at the same time. The discharging device 200 is used to place the second material (i.e., desiccant) and the third material (i.e., humidity card) near the stacked PCBs, wherein the desiccant can continuously dry the PCBs, and the humidity card is used to display the humidity of the environment in which the PCBs are located. The packaging device 300 is used to make the second film tape (such as PE film) and the first film tape (such as foam) fit together, and to suck the air between the second film tape and the first film tape to complete the vacuum packaging of the PCBs. The cutting device 400 is used to cut the bonded second film tape and the first film tape, thereby dividing a large piece of the second film tape and the first film tape into several small pieces. Each piece of the second film tape and the first film tape is wrapped with a group of stacked PCBs, thereby facilitating subsequent transportation.

[0052] Reference Figure 3 、 Figure 4 and Figure 9 , Figure 3 yes Figure 1 Axonometric drawing of the loading device, Figure 4 yes Figure 1 A front view of the feeding device 100, Figure 9 yes Figure 1 A bottom view of the loading mechanism 150 and the photographing device 180. The loading device of this embodiment includes a first film strip loading device 120, an auxiliary loading device 130, a material preparation platform 140, a loading mechanism 150, a first loading platform 160, a recovery platform 170, and a photographing device 180. The auxiliary loading device 130 is located on the left side of the material preparation platform 140. After being conveyed by the auxiliary loading device 130, the incoming PCBs are placed on the material preparation platform 140. When the material preparation platform 140 is in operation, the PCBs can be placed on the auxiliary loading device 130 first, thereby ensuring that the material preparation platform 140 can continuously load materials and the production rhythm is not interrupted.

[0053] The photographing device 180 is used to take photos of the PCBs on the material preparation platform 140. The photos taken are used to analyze the placement direction of the PCBs (front or back) and to detect whether the material numbers of the PCBs are complete and clear. The loading mechanism 150 is used to transfer PCBs with the correct placement direction and qualified material numbers to the first loading platform 160. In addition, the loading mechanism 150 is also used to transfer PCBs with the reverse placement direction or unqualified material numbers to the recycling platform 170. The first film tape loading device 120 is used to provide a first film tape (such as foam). The first film tape led out by the first film tape loading device 120 is unfolded on the first loading platform 160, and the PCBs are stacked on the first film tape.

[0054] In order to improve the loading efficiency, two auxiliary loading devices 130 are provided, and two material preparation platforms 140 are also provided accordingly, with one auxiliary loading device 130 corresponding to one material preparation platform 140 .

[0055] In another embodiment, one auxiliary loading device 130 and one material preparation platform 140 may be provided respectively.

[0056] The frame 500 includes a first mounting plate 511 , a second mounting plate 512 and a third mounting plate 513 . The material preparation platform 140 is mounted on the first mounting plate 511 , the loading mechanism 150 is mounted on the second mounting plate 512 , and the first loading platform 160 is mounted on the third mounting plate 513 .

[0057] Reference Figure 3 The auxiliary loading device 130 includes a first reduction motor 131, a coupling, a first support rod 132, a first conveyor belt 133, a first roller, and a second roller. A single auxiliary loading device 130 includes two first support rods 132, which are arranged in parallel and spaced apart. The length direction of the first support rods 132 is arranged in the left-right direction, and the first support rods 132 are fixedly connected to the frame 500 (locked by fasteners). The first roller and the second roller are arranged between the two first support rods 132 and arranged in parallel. The first roller is located to the right of the second roller. The two ends of the first roller are respectively connected to the two first support rods 132 for rotation via a first bearing, and the two ends of the second roller are respectively connected to the two first support rods 132 for rotation via a second bearing. The first conveyor belt 133 is sleeved on the first roller and the second roller, and the first roller and the second roller tighten the first conveyor belt 133.

[0058] The first reduction motor 131 is a combination of a motor and a reducer. Its output shaft is fixedly connected to one end of the first roller's rotating shaft via a coupling. Consequently, when the first reduction motor 131 is powered, the first roller drives the first conveyor belt 133 to rotate. Incoming PCBs can be placed on the first conveyor belt 133. Once the material preparation platform 140 is clear, the first reduction motor 131 is activated to transfer the PCBs to the material preparation platform 140, achieving seamless loading.

[0059] Reference Figure 3 The first loading platform 160 includes a first rectangular frame 161, a third roller 162, a fourth roller, a second conveyor belt 163, and a twelfth drive device. The third roller 162 and the fourth roller are arranged side by side, with the fourth roller located to the left of the third roller 162. The front end of the third roller 162 is rotatably connected to the front side of the first rectangular frame 161, and the rear end of the third roller 162 is rotatably connected to the rear side of the first rectangular frame 161. The same applies to the fourth roller. The second conveyor belt 163 is mounted on the third roller 162 and the fourth roller, and the third and fourth rollers 162 and the fourth rollers tension the second conveyor belt 163. As a result, the upper surface of the second conveyor belt 163 forms a first working surface, on which the first film strip and PCBs can be placed. The twelfth drive device is used to drive the second conveyor belt 163 to rotate, thereby facilitating the flow of PCBs placed on the first film strip to the next process step.

[0060] The twelfth driving device includes a second motor, a first synchronous wheel, a first synchronous belt and a second synchronous wheel. The rotating shaft of the second motor is fixedly connected to the second synchronous wheel (connected by a key and a set screw), and the first synchronous wheel is fixedly connected to the rear end of the third roller 162 (refer to Figure 3 or Figure 4 , connected by a key and set screws). The first synchronous belt is mounted on the second synchronous pulley and the first synchronous pulley, and the teeth on the inner annular surface of the first synchronous belt mesh with the teeth on the outer circumferential surface of the second synchronous pulley and the teeth on the outer circumferential surface of the first synchronous pulley. Therefore, when the second motor is energized, the second motor's shaft drives the third roller 162 to rotate through the second synchronous pulley, the first synchronous belt, and the first synchronous pulley, ultimately driving the second conveyor belt 163 to rotate.

[0061] Reference Figure 3 The recovery platform 170 is a tray, and two trays are provided. The two trays are fixed to the front end and the rear end of the first rectangular frame 161 by screws respectively.

[0062] Reference Figure 5 and Figure 6 , Figure 5 yes Figure 1 Axonometric view of the first film strip loading device 120 and part of the frame 500, Figure 6 yes Figure 1Exploded view of the first film tape loading device 120 and part of the frame 500. The first film tape loading device 120 includes a first material roller 121, a third adjustment device, a first mounting frame 123, a first bearing seat 124, a third bearing, a first passing roller 126 and a second passing roller. The first material roller 121 is used to wind the first film tape, and the first material roller 121 is rotatably connected to the first mounting frame 123. Specifically, two first bearing seats 124 and two third bearings are respectively provided, and one third bearing and one first bearing seat 124 are used in conjunction with each other. The rear end of the first material roller 121 is fixedly connected to the inner ring of the third bearing, and the outer ring of the third bearing is fixedly connected to the first bearing seat 124. The first bearing seat 124 is fixed to the first mounting frame 123 by screws. By providing two sets of first bearing seats 124 and third bearings, the first material roller 121 can rotate smoothly.

[0063] In order to adjust the front-to-back position of the first film strip on the first loading platform 160, thereby stacking the PCB in the appropriate position on the first film strip, a third adjustment device is provided. The third adjustment device includes an electric cylinder 122 and a first sliding assembly 125. The first sliding assembly 125 includes a first slider and a first slide rail. The first slider is slidably connected to the first slide rail. The sliding direction of the first slider is set in the front-to-back direction. The first slide rail is screwed to the frame 500, and the first mounting bracket 123 is screwed to the first slider. The piston rod of the electric cylinder 122 is fixedly connected to the first mounting bracket 123 by screws. Therefore, when the electric cylinder 122 is energized, the first material roller 121 will move forward or backward, and the front-to-back position of the first film strip drawn from the first material roller 121 on the first loading platform 160 can be adjusted.

[0064] To guide the first film ribbon, a first roller 126 and a second roller are provided. Both the first roller 126 and the second roller are rotatably connected to the frame 500 (via bearings and bearing blocks). The first roller 126 is positioned on the left side of the first mounting plate 511, while the second roller is positioned on the lower surface of the first mounting plate 511, adjacent to the through-hole 514 in the first mounting plate 511. The first film ribbon, which is drawn from the first material roller 121, passes over the first roller 126 and the second roller, then through the through-hole 514, before being deposited on the first loading platform 160.

[0065] Reference Figure 7 and Figure 8 , Figure 7 yes Figure 1 Axonometric view of the middle material preparation platform 140 and part of the rack 500, Figure 8 yes Figure 1Exploded view of the material preparation platform 140. The material preparation platform 140 is provided to assist the loading mechanism 150 in loading. The material preparation platform 140 includes an eighth drive device, a lifting platform, and a positioning mechanism. The lifting platform is used to place incoming PCBs (usually in a stacked state). The eighth drive device can drive the lifting platform to move upward or downward, so that after a portion of the PCB is removed, the remaining PCBs are automatically raised to facilitate loading by the loading mechanism 150. The positioning mechanism is used to position the PCB to prevent the PCB on the lifting platform from deviating from the material removal position and affecting the loading of the loading mechanism 150.

[0066] Specifically, the lifting platform includes a first mounting base 146, a conveyor roller 147, and a ninth drive unit. The ninth drive unit includes a second reduction motor 145, a chain, a first sprocket, and a second sprocket. Both ends of the conveyor roller 147 are rotatably connected to the first mounting base 146 (via bearings), allowing the conveyor roller 147 to rotate about a longitudinal axis. Multiple conveyor rollers 147 are provided, arranged in parallel and spaced apart. The first sprocket is secured to the output shaft of the second reduction motor 145 via a key and set screws, the second sprocket is secured to the front end of the conveyor roller 147, and the chain is mounted on the first and second sprockets. Thus, when the second reduction motor 145 is energized, the conveyor roller 147 rotates along the longitudinal axis, and once the PCB is loaded onto the conveyor roller 147, it automatically moves from left to right.

[0067] In order to make the lifting platform move in the up and down direction, an eighth drive device is provided. The eighth drive device includes a first motor 141, a first slide 142, a second synchronous belt 143, a third synchronous wheel, a fourth synchronous wheel and a second sliding assembly 144. The rotating shaft of the first motor 141 is fixedly connected to the third synchronous wheel (connected by a key and a set screw), and the fourth synchronous wheel is rotatably connected to the frame 500. The second synchronous belt 143 is mounted on the third synchronous wheel and the fourth synchronous wheel, and the teeth on the inner annular surface of the second synchronous belt 143 are engaged with the teeth on the outer circumferential surface of the third synchronous wheel and the teeth on the outer circumferential surface of the fourth synchronous wheel. The first slide 142 is clamped on the second synchronous belt 143 by fasteners, and the first slide 142 is fixedly connected to the first mounting seat 146 (connected by fasteners).

[0068] To guide the lifting platform, a second sliding assembly 144 is provided. This second sliding assembly 144 includes a second slider and a second slide rail. The second slider and the second slide rail are slidably connected, and the second slider slides in the vertical direction. Both ends of the second slide rail are fixedly connected to the frame 500 (fastened by screws), while the second slider is screwed to the first mounting bracket 146. Two sets of second sliding assemblies 144 are provided, spaced apart in the left-right direction.

[0069] Therefore, when the first motor 141 is powered on, the second synchronous belt 143 will move the lifting platform in the up and down directions.

[0070] In order to position the PCBs stacked on the lifting platform, a positioning mechanism is provided. The positioning mechanism includes a first positioning plate 149, a tenth drive device 191, a second positioning plate 193, an eleventh drive device 192, and a positioning frame. The positioning frame includes a fourth mounting plate 148, a fifth mounting plate 194, a first limiting rod 195, and a second limiting rod 196. There are multiple second limiting rods 196, and the multiple second limiting rods 196 are arranged at intervals along the left-right direction. The length direction of the second limiting rods 196 is arranged along the up-down direction. There are four fourth mounting plates 148, and the length direction of the fourth mounting plates 148 is arranged along the left-right direction. Two fourth mounting plates 148 are arranged at intervals up and down, and the remaining two fourth mounting plates 148 are also arranged at intervals up and down. The two ends of half of the second limiting rods 196 are respectively fixed to the two fourth mounting plates 148, and the two ends of the other half of the second limiting rods 196 are respectively fixed to the remaining two fourth mounting plates 148.

[0071] There are multiple first limiting rods 195 arranged at intervals along the front-to-back direction. Two fifth mounting plates 194 are provided, and the two fifth mounting plates 194 are spaced apart from each other. The ends of the first limiting rods 195 are fixed to the two fifth mounting plates 194 respectively.

[0072] Thus, the positioning frame forms a "U"-shaped frame.

[0073] The first positioning plate 149 is fixed to the output end of the tenth driving device 191. Under the action of the tenth driving device 191, the first positioning plate 149 will move in a first direction (in this embodiment, the first direction is the left-right direction). The second positioning plate 193 is fixed to the output end of the eleventh driving device 192. Under the action of the eleventh driving device 192, the second positioning plate 193 will move in a second direction (in this embodiment, the second direction is the front-back direction).

[0074] Thus, when the first positioning plate 149 approaches the first limiting rod 195, the PCBs stacked on the lifting platform will be pushed by the first positioning plate 149, so that they are closely attached to the first limiting rod 195; when the second positioning plate 193 approaches the second limiting rod 196, the PCBs stacked on the lifting platform will be pushed by the second positioning plate 193, so that they are closely attached to the second limiting rod 196. Ultimately, the PCBs are completely positioned on the horizontal plane.

[0075] In other embodiments, the angle between the first direction and the second direction may also be 80°, 60°, or 45°, that is, non-parallel. As long as the PCB is finally placed close to the right angle of the positioning frame, the PCB can be positioned on the horizontal plane.

[0076] In this embodiment, the tenth driving device 191 is a third cylinder, and the eleventh driving device 192 is a fourth cylinder. In another embodiment, the tenth driving device 191 and the eleventh driving device 192 may also be electric push rods.

[0077] To adjust the distance between first positioning plate 149 and first limiting rod 195, a plurality of second adjustment holes are provided on the upper fourth mounting plate 148, spaced apart in the left-right direction. The cylinder body of the first cylinder is screwed to the adjustment plate, which has waist-shaped holes along the left-right direction. The adjustment plate is secured to the fourth mounting plate 148 by screws passing through the second adjustment holes and the waist-shaped holes. Thus, by adjusting the left-right position of the first cylinder, the distance between first positioning plate 149 and first limiting rod 195 can be adjusted to accommodate PCBs of varying sizes. The distance between second positioning plate 193 and second limiting rod 196 can be adjusted similarly.

[0078] Reference Figure 9 In this embodiment, the loading mechanism 150 includes a parallel manipulator 151 and a first material picking head 152. The first material picking head 152 is a first suction nozzle, and the first suction nozzle is connected to the negative pressure air source. Since the parallel manipulator needs to drive the first suction nozzle downward to obtain or release the material, and drive the first suction nozzle upward to move away from the lifting platform, the first loading platform 160 or the recovery platform 170, the parallel manipulator needs to have the freedom to move in the up and down directions. Since the parallel manipulator needs to drive the first suction nozzle from the lifting platform to the first loading platform 160, the parallel manipulator needs to have the freedom to move in the left and right directions. Since the parallel manipulator needs to drive the first suction nozzle from the lifting platform to the recovery platform 170, the parallel manipulator needs to have the freedom to move in the left and right directions and in the front and back directions. In summary, the parallel manipulator 151 needs to have three degrees of freedom: movement in the front and back directions, movement in the left and right directions, and movement in the up and down directions. The parallel manipulator 151 has the characteristics of compact structure and small working space, which can reduce the volume of the loading device as a whole and reduce the space occupied.

[0079] In another embodiment, the parallel manipulator 151 may also be replaced by a three-axis manipulator.

[0080] In this embodiment, the photographing device 180 is a CCD camera, which is fixed to the output end of the parallel manipulator. Before the first suction nozzle picks up the PCB, the CCD camera first takes a picture of the PCB, thereby determining whether to transfer the PCB to the first loading platform 160 or the recovery platform 170.

[0081] In another embodiment, the camera device 180 may also be a CMOS camera.

[0082] Reference Figure 10 , Figure 10 yes Figure 1 Axonometric view of the discharge device 200. The discharge device 200 includes a first discharge assembly 230, a second discharge assembly 240, a storage platform 250, and a vibrating tray 260. The storage platform 250 is used to place the stacked humidity cards (i.e., the third material), and the vibrating tray 260 is used to arrange and discharge the desiccant (i.e., the second material) in packages. The first discharge assembly 230 is used to transfer the desiccant from the vibrating tray 260 to the first work surface, where the desiccant is placed diagonally on the stacked PCBs. The second discharge assembly 240 is used to transfer the humidity cards to the first work surface, where they are placed on the stacked PCBs. As a result, after the discharge device discharges the PCBs, at least one package of desiccant and one humidity card are placed next to each stack of PCBs.

[0083] Reference Figure 10 and Figure 11 , Figure 11 yes Figure 1 Exploded view of the storage platform 250. The storage platform 250 includes a support base 251, a fourteenth drive device, and a silo 253. The fourteenth drive device is a rotary cylinder 252. The silo 253 is provided with a plurality of upwardly extending limit bars 255, which enclose two material preparation positions 254, in which stacked humidity cards can be placed. The silo 253 is fixed to the turntable of the rotary cylinder 252 by screws, and the cylinder body of the rotary cylinder 252 is fixed to the frame 500 via the support base 251. After the rotary cylinder 252 is ventilated, the silo 253 can rotate on a horizontal plane. After the silo 253 rotates 180°, the two material preparation positions 254 will swap positions. Thus, when the humidity card in one preparation position 254 is used up, the other preparation position 254 loaded with humidity cards can be switched to the material taking position by rotating the hopper 253, and the vacant preparation position 254 can be refilled. In this way, the material taking process of the humidity card is not interrupted, and the humidity card can be continuously loaded.

[0084] In another embodiment, the fourteenth driving device may also use a servo motor, which can also realize the position switching of the two preparation positions 254.

[0085] In another embodiment, the fourteenth driving device can also be a linear motor or a common cylinder, and the hopper 253 can achieve position switching of the two preparation positions 254 by translating in the left and right directions. In addition, the number of the preparation positions 254 can also be three, four or five.

[0086] Reference Figure 10 、 Figure 12 and Figure 13 , Figure 12 yes Figure 1 Exploded view of the first drive unit, Figure 13 yes Figure 1 Exploded view of the second drive unit, the third drive unit and the second material picking head 233. The first discharge assembly 230 includes a first drive unit, a second drive unit, a third drive unit and a second material picking head 233. The first drive unit is used to drive the second material picking head 233 to move in the front-to-back direction and in the left-to-right direction, so that the second material picking head 233 can reach any position on the first working surface. The second drive unit is used to drive the second material picking head 233 to move in the up-down direction, so that the second material picking head 233 can approach the vibration disk 260 to obtain the desiccant, and the second material picking head 233 can approach the first working surface to place the desiccant next to the PCB. The third drive unit can rotate the second material picking head 233 around an axis on the horizontal plane, so that the second material picking head 233 can place the desiccant obliquely on the stacked PCBs. After the air between the foam and the PE film is extracted, the desiccant is tightly attached to the PCB.

[0087] Reference Figure 12 Specifically, the first drive device includes a first drive assembly 231, a second drive assembly 232, and a sixth mounting plate 234. The second drive assembly 232 is disposed on the output end of the first drive assembly 231, the sixth mounting plate 234 is fixed to the output end of the second drive assembly 232, and the second reclaiming head 233 is disposed on the sixth mounting plate 234. The first drive assembly 231 is used to drive the second reclaiming head 233 to move in the left-right direction, and the second drive assembly 232 is used to drive the second reclaiming head 233 to move in the front-back direction.

[0088] The first drive assembly 231 includes a second slide 281, a third synchronous wheel 282, a second synchronous belt 283, a fourth synchronous wheel 284, a first synchronous wheel assembly 285, a third motor 286, a second support rod 287, a third synchronous belt 288, and a third sliding assembly 289. The second support rod 287 is an aluminum profile. Its length runs in the left-right direction, and a first passage is provided within the second support rod 287 along the left-right direction. Two first synchronous wheel assemblies 285 are provided: one is located at the left end of the second support rod 287, and the other is located at the right end of the second support rod 287. The first synchronous wheel assembly 285 includes a fifth synchronous wheel and a first housing. The fifth synchronous wheel is located within the first housing and is rotatably connected to the first housing. The first housing is screwed to the second support rod 287. The third synchronous belt 288 is mounted on the two fifth synchronous wheels. The lower half of the third synchronous belt 288 is located in the first channel of the second support rod 287, and the upper half of the third synchronous belt 288 is located above the second support rod 287. The second slide 281 is fastened to the third synchronous belt 288 by fasteners.

[0089] The rotating shaft of the third motor 286 is fixedly connected to the third synchronous gear 282 (via an expansion sleeve), and the fourth synchronous gear 284 is fixedly connected to the fifth synchronous gear located at the left end of the second support rod 287 (via an expansion sleeve). The second synchronous belt 283 is mounted on the third and fourth synchronous gears 282, 284. Therefore, when the third motor 286 is energized, the second slide 281 moves in the left and right directions. In other words, the second slide 281 serves as the output end of the first drive assembly 231.

[0090] To provide support and guide the movement of the second drive assembly 232, a third sliding assembly 289 is provided. The third sliding assembly 289 comprises a third rail and a third slider, which are slidably connected to each other. The length of the third rail runs in the left-right direction, allowing the third slider to slide in the left-right direction on the third rail. The third rail is secured to the frame 500 with screws. Both the second slide 281 and the third slider are connected to the second drive assembly 232.

[0091] The structure of the second drive assembly 232 is similar to that of the first drive assembly 231. The difference between the second drive assembly 232 and the first drive assembly 231 is that the second drive assembly 232 does not include the third sliding assembly 289. Specifically, the second drive assembly 232 includes a sixth synchronous wheel, a fourth synchronous belt, a seventh synchronous wheel, a fourth motor, a second synchronous wheel assembly, a fifth synchronous belt, a third support rod 291 and a third slide. The length direction of the third support rod 291 is arranged along the front-to-back direction, and a second through channel is arranged in the third support rod 291 along the front-to-back direction. The third support rod 291 is fixedly connected to the second slide 281 and the third slider respectively (locked by screws).

[0092] Two second synchronous wheel assemblies are provided, one at the front end of the third support rod 291, and the other at the rear end of the third support rod 291. The second synchronous wheel assembly includes an eighth synchronous wheel and a second housing, the eighth synchronous wheel being rotatably connected to the second housing. A fifth synchronous belt is sleeved over the two eighth synchronous wheels, the lower half of the fifth synchronous belt being located in the second channel of the third support rod 291, and the upper half of the fifth synchronous belt being located above the third support rod 291. The third slide is fixed to the fifth synchronous belt (fastened by fasteners). The fourth motor drives the eighth synchronous wheel to rotate via the sixth synchronous wheel, the fourth synchronous belt, and the seventh synchronous wheel, thereby driving the third slide to move in the forward and backward directions.

[0093] The sixth mounting plate 234 is fixed on the third slide platform by screws.

[0094] In another embodiment, both the first driving assembly 231 and the second driving assembly 232 may be replaced by a combination of a motor, a lead screw, and a nut.

[0095] Reference Figure 13 The second drive 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 fixed to the sixth mounting plate 234 by screws, and the first mounting block 294 is fixed to the first piston rod of the first cylinder 292 (fixed by a nut). The second cylinder body of the second cylinder 295 is fixed to the first mounting block 294 by screws, and the second mounting block 299 is fixed to the second piston rod of the second cylinder 295 (fixed by a nut). The second material removal head 233 is set on the second mounting block 299. Therefore, whether the first cylinder 292 or the second cylinder 295 is actuated, the second material removal head 233 can be moved in the up and down direction.

[0096] Furthermore, the stroke of the second reclaiming head 233 is the sum of the strokes of the first and second cylinders 292, 295, with the stroke of the first cylinder 292 being significantly greater than the stroke of the second cylinder 295 (approximately several to more than ten times). Consequently, when the second reclaiming head 233 approaches the vibrating plate 260 or the first working surface, the first cylinder 292 can be activated first. Once the second reclaiming head 233 is near the vibrating plate 260 or the first working surface, the second cylinder 295 can then be activated to complete the reclaiming operation. By designing the stroke of the second reclaiming head 233 as the sum of the long and short strokes, the displacement accuracy of the second reclaiming head 233 can be improved. Specifically, the final stroke of the second reclaiming head 233 is completed by the second cylinder 295, and due to the short stroke of the second cylinder 295, large errors are less likely to occur.

[0097] In another embodiment, the second driving device may also be replaced by a combination of a motor, a lead screw and a nut.

[0098] The third drive mechanism includes a positioning block 297 and an oscillating cylinder 298. The cylinder body of oscillating cylinder 298 is screwed to a second mounting block 299, while the positioning block 297 is also screwed to the cylinder body of oscillating cylinder 298. Oscillating cylinder 298 includes a rocker arm 296, one end of which is fixedly connected to the rotating shaft of oscillating cylinder 298. A second material removal head 233 is fixed to the other end of rocker arm 296. This second material removal head 233 is a second suction nozzle. When connected to a negative pressure air source (such as a vacuum pump), it can absorb the desiccant.

[0099] When the second suction nozzle draws material from vibrating plate 260, it remains in a vertical position. Driven by the first and second drive mechanisms, the second suction nozzle moves near the stacked PCBs. The swing cylinder 298 rotates the rocker arm 296 until it abuts against the positioning block 297. At this point, the negative pressure on the second suction nozzle disappears, and the desiccant rests against the stacked PCBs. After subsequent vacuuming, the desiccant adheres tightly to the PCBs, continuously absorbing moisture from the vicinity.

[0100] 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 second suction nozzle returns to the vertical state, thereby carrying out the next material removal.

[0101] Reference Figure 10 、 Figure 12 and Figure 14 , Figure 14 yes Figure 1 Exploded view of the second material discharging assembly 240. The second material discharging assembly 240 includes a first drive device, a thirteenth drive device, and a third material discharging head 241. The thirteenth drive device is arranged on the output end of the first drive device (i.e., the sixth mounting plate 234), and the third material discharging head 241 is arranged on the output end of the thirteenth drive device. The first drive device is used to drive the third material discharging head 241 to move in the front-to-back direction and in the left-to-right direction, so that the third material discharging head 241 can reach any position on the first working surface. The thirteenth drive device is used to drive the third material discharging head 241 to move in the up-down direction, so that the third material discharging head 241 can approach the material storage platform 250 to obtain the humidity card, and so that the third material discharging head 241 can approach the first working surface to place the humidity card on the PCB. The third material discharging head 241 is a third suction nozzle.

[0102] The second discharge assembly 240 and the first discharge assembly 230 share the first driving device, thereby saving material costs, simplifying the structure of the discharge device, reducing the space occupied by the discharge device, and improving the competitiveness of the discharge device.

[0103] Reference Figure 14The thirteenth driving device includes a second mounting seat 242, a linear bearing 243, a polished rod 244, a connecting plate 245, a first nut 246, a first screw rod 247, a fifth motor 248, a rolling bearing 249, a ninth synchronous wheel, a tenth synchronous wheel and a sixth synchronous belt. The second mounting seat 242 is fixed to the mounting plate 234 by screw locking. Two rolling bearings 249 are provided, and the lower end of the first screw rod 247 is rotatably connected to the second mounting seat 242 through the two rolling bearings 249. The rotating shaft of the fifth motor 248 is connected to the lower end of the first screw rod 247 through the ninth synchronous wheel, the tenth synchronous wheel and the sixth synchronous belt, and the first nut 246 is threadedly engaged with the first screw rod 247. The polished rod 244 is slidably connected to the second mounting seat 242 through the linear bearing 243, and the upper end of the polished rod 244 is fixedly connected to the first nut 246 through the connecting plate 245. The third suction nozzle is fixed to the lower end of the polished rod 244. Therefore, after the fifth motor 248 is powered on, the polished rod 244 will move the third suction nozzle in the up and down directions.

[0104] In another embodiment, the thirteenth driving device may also be a rotary cylinder or a linear motor.

[0105] In summary, initially, the second suction nozzle, driven by the second drive mechanism, moves downward to absorb desiccant from the vibrating plate 260. Subsequently, the second drive mechanism moves upward to avoid collision with PCBs or other objects during subsequent movement. Simultaneously, the third suction nozzle, driven by the thirteenth drive mechanism, moves downward to absorb the humidity card from the preparation position 254. Subsequently, the thirteenth drive mechanism moves upward to avoid collision with PCBs or other objects during subsequent movement.

[0106] Next, the second and third nozzles are moved closer to a group of PCBs under the control of the first drive. The second nozzle then moves downward under the control of the second drive, approaching the first work surface. After the second drive completes its stroke, the second nozzle tilts under the control of the third drive, placing the desiccant against the PCBs. Once the desiccant is placed, the second nozzle returns to its upright position under the control of the third drive and moves upward under the control of the second drive. The third nozzle then moves downward under the control of the thirteenth drive, placing the humidity card on the PCBs, and then moves upward under the control of the thirteenth drive.

[0107] Finally, the second and third nozzles, under the action of the first drive device, return to the material-retrieving position, thus completing one material-unloading operation. Next, the material-unloading operation is carried out for each group of PCBs on the first working surface.

[0108] Reference Figure 15 、 Figure 16 and Figure 22 , Figure 15yes Figure 1 Axonometric drawing of the middle packaging device, Figure 16 yes Figure 1 Axonometric view of the second loading platform 320, the negative pressure device 360 ​​and part of the frame 500, Figure 22 yes Figure 1 The packaging device includes a second loading platform 320, a second film strip feeding device 330, a heating device 340, a laminating device 350, a negative pressure device 360 ​​(refer to Figure 17 ) and the cutting device 370 (refer to Figure 22 ). The second loading platform 320 is used to place the opened first film tape (such as pearl cotton), and one or more groups of stacked PCBs are placed on the first film tape. The second film tape loading device 330 is used to pull out the wound second film tape and continuously provide a certain length of the second film tape. The cutting device 370 is used to cut off the pulled-out second film tape to facilitate the lamination of the second film tape and the first film tape. The heating device 340 is used to heat the second film tape (such as a PE film) to soften the second film tape. The softened second film tape is easy to deform and has a certain viscosity. The laminating device 350 is used to laminar the heated second film tape on the first film tape. The negative pressure device 360 ​​is used to extract the air between the second film tape and the first film tape after lamination, so that the second film tape and the first film tape are tightly fitted, and the softened second film tape can be adhered to the first film tape. The PCB is isolated from the air to prevent the PCB from being oxidized.

[0109] Reference Figures 15 to 17 , Figure 17 yes Figure 1 Exploded view of the second loading platform 320 and negative pressure device 360. The second loading platform 320 includes a second rectangular frame 321, a third conveyor belt 322, a fifth roller 323, a sixth roller 324, and a fifteenth drive device. The frame 500 also includes a support plate 515, with the second rectangular frame 321 fixed to the upper surface of the support plate 515 by screws. The fifth roller 323 and the sixth roller 324 are arranged side by side, with the sixth roller 324 located to the right of the fifth roller 323. The front end of the fifth roller 323 is rotatably connected to the front side of the second rectangular frame 321 (via a bearing), and the rear end of the fifth roller 323 is rotatably connected to the rear side of the second rectangular frame 321 (via a bearing). The sixth roller 324 is connected in the same manner. The third conveyor belt 322 is mounted on the fifth roller 323 and the sixth roller 324, which tension the third conveyor belt 322. Thus, the upper surface of the third conveyor belt 322 forms a second working surface 326. The fifteenth driving device is used to drive the third conveyor belt 322 to rotate, thereby facilitating the first film tape with one or more sets of PCBs placed thereon to enter the second working surface 326.

[0110] The fifteenth drive device includes a sixth motor, a first synchronous wheel, a first synchronous belt, and a second synchronous wheel. The sixth motor's shaft is fixedly connected to the second synchronous wheel (via a key and set screw), and the first synchronous wheel is fixedly connected to the front end of the fifth roller 323 (via a key and set screw). The first synchronous belt is mounted on the second synchronous wheel and the first synchronous wheel, and the teeth on the inner annular surface of the first synchronous belt mesh with the teeth on the outer circumferential surface of the second synchronous wheel and the teeth on the outer circumferential surface of the first synchronous wheel. Therefore, when the sixth motor is energized, the sixth motor's shaft drives the fifth roller 323 to rotate via the second synchronous wheel, the first synchronous belt, and the first synchronous wheel, ultimately driving the third conveyor belt 322 to rotate.

[0111] Negative pressure device 360 ​​includes an outlet pipe 361 and a housing 362. Housing 362 defines a cavity. One end of outlet pipe 361 communicates with the cavity, while the other end of outlet pipe 361 communicates with a vacuum pump. A plurality of third through holes 363 are arranged in an array on the upper surface of housing 362, communicating with the cavity.

[0112] To improve the efficiency of negative pressure formation, four air outlet pipes 361 are provided, and all four air outlet pipes 361 are connected to the vacuum pump. Among them, two air outlet pipes 361 are provided on the front side of the box body 362, and the remaining two air outlet pipes 361 are provided on the rear side of the box body 362.

[0113] To enable the negative pressure device 360 ​​to more quickly draw air from the third conveyor belt 322, a plurality of second through holes 325 are arranged in an array along the circumferential direction of the third conveyor belt 322. Thus, when the vacuum pump is operating, it draws air from the third conveyor belt 322 sequentially through the air outlet pipe 361, the cavity, the third through holes 363, and the second through holes 325.

[0114] In another embodiment, the function of the second loading platform 320 can also be directly realized by the box 362 , that is, the first film tape with one or more groups of PCBs placed thereon is directly placed on the upper surface of the box 362 .

[0115] Reference Figure 15 、 Figure 18 and Figure 19 , Figure 18 yes Figure 1 Axonometric view of the second film strip loading device 330 and part of the frame 500, Figure 19 yes Figure 1Exploded view of the second film tape loading device 330 and part of the frame 500. In order to continuously realize the loading of the second film tape, a second film tape loading device 330 is provided. The second film tape loading device 330 includes a second bearing seat 331, a seventh mounting plate 332, a second material roller 333, a third roller 334, a fourth driving device, a fourth support rod 335, a first clamp and a second clamp. The second material roller 333 is rotatably connected to the frame 500, and the second material roller 333 is used to wind the second film tape. Specifically, the rear end of the second material roller 333 is fixedly connected to the inner ring of the fourth bearing, and the outer ring of the fourth bearing is fixed on the second bearing seat 331. The second bearing seat 331 is locked on the seventh mounting plate 332 by screws, and the seventh mounting plate 332 is locked on the frame 500 by screws. A support is provided at the front end of the second material roller 333. One end of the support is fixed to the frame 500 via screws. Two fifth bearings are also rotatably mounted on the support (the inner rings of the fifth bearings are fixedly connected to the support). The right end of the second material roller 333 is tangential to the outer rings of the two fifth bearings. Thus, the second material roller 333 is rotatably connected to the frame 500.

[0116] In order to enable the second material roller 333 to wind more second film tapes and withstand greater force, two sets of fourth bearings and a second bearing seat 331 are provided at the left end of the second material roller 333 .

[0117] The fourth drive device is used to drive the first clamping jaw to move horizontally. Specifically, the fourth drive device includes a seventh motor 381, a third synchronous wheel, a second synchronous belt, a fourth synchronous wheel, a first connecting shaft 382, ​​a first synchronous wheel assembly 383, a third synchronous belt, a fourth slide 384, and a second synchronous wheel assembly 385. Two fourth support rods 335 are provided, arranged side by side and spaced apart. The length of the fourth support rods 335 runs in the horizontal direction, and both fourth support rods 335 are fixed to the frame 500 by screws. Two sets of the first synchronous wheel assembly 383, the third synchronous belt, the fourth slide 384, and the second synchronous wheel assembly 385 are provided: one set is provided on the front side of the fourth support rod 335, and the other set is provided on the rear side of the fourth support rod 335.

[0118] The fourth support rod 335 is an aluminum profile and has a third channel extending therethrough in the left-right direction. The lower half of the third synchronous belt is located in the third channel of the fourth support rod 335, while the upper half of the third synchronous belt is located above the fourth support rod 335. The first synchronous pulley assembly 383 is located at the left end of the fourth support rod 335, and the second synchronous pulley assembly 385 is located at the right end of the fourth support rod 335.

[0119] The first synchronous wheel assembly 383 includes a fifth synchronous wheel and a first housing. The fifth synchronous wheel is located within the first housing and is rotatably connected to the first housing. The first housing is screwed to the right end of the fourth support rod 335. Similarly, the second synchronous wheel assembly 385 includes a sixth synchronous wheel and a second housing. The sixth synchronous wheel is located within the second housing and is rotatably connected to the second housing. The second housing is screwed to the left end of the fourth support rod 335.

[0120] The third synchronous belt is mounted on the fifth and sixth synchronous wheels, and the fourth slide 384 is secured to the third synchronous belt via fasteners. The rotating shaft of the seventh motor 381 is fixedly connected to the third synchronous wheel (via an expansion sleeve), and the fourth synchronous wheel is fixedly connected to the rotating shaft of the fifth synchronous wheel located on the rear fourth support rod 335 (via an expansion sleeve). The second synchronous belt is mounted on the third and fourth synchronous wheels. The two fifth synchronous wheels are fixedly connected via a first connecting shaft 382 and a coupling. As a result, when power is supplied to the seventh motor 381, the two third synchronous belts rotate synchronously.

[0121] In this embodiment, the first clamping jaw is a first cylinder clamping jaw 336, and the second clamping jaw is a second cylinder clamping jaw 337. Two first cylinder clamping jaws 336 and two second cylinder clamping jaws 337 are provided. The two first cylinder clamping jaws 336 are respectively fixed to the two fourth slides 384, and the two second cylinder clamping jaws 337 are both fixed to the frame 500 by screws.

[0122] Therefore, when the second film strip is first drawn out, it is manually passed over the third roller 334 and then pulled to the first cylinder clamp 336. The third roller 334 acts as a guide, changing the movement path of the second film strip. The two first cylinder clamps 336 respectively clamp the two side edges of the second film strip. Next, the fourth drive device drives the two first cylinder clamps 336 to move rightward, approaching the second cylinder clamp 337. When the second film strip moves to the second cylinder clamp 337, the two second cylinder clamps 337 simultaneously clamp the right end of the second film strip. Finally, the two first cylinder clamps 336 return to their original position under the action of the fourth drive device, once again clamping the two side edges of the second film strip, waiting for the next time the second film strip is pulled to the second cylinder clamp 337.

[0123] In other embodiments, the number of first cylinder jaws 336 can be three, four, or six, and the first cylinder jaws 336 can be evenly or approximately evenly distributed on both sides of the second film strip. Providing more first cylinder jaws 336 can prevent the second film strip from falling off during the pulling process. The same applies to the second cylinder jaws 337.

[0124] In another embodiment, the first clamp is a first electric clamp, the second clamp is a second electric clamp, the installation position of the first electric clamp is the same as the first cylinder clamp 336, and the installation position of the second electric clamp is the same as the second cylinder clamp 337.

[0125] Reference Figure 15 and Figure 20 , Figure 20 yes Figure 1 A bottom view of the heating device 340. Located at the top of the packaging device, the heating device 340 includes a second heating element 341 and a ventilation hood 342. The second heating element 341 heats the second film strip, softening it. The softened second film strip is easily deformed and has a certain degree of stickiness. This allows the second film strip to adhere to the first film strip easily after the air between them is removed. After cooling, the second film strip can adhere to the first film strip, thereby wrapping the PCB and protecting it from moisture in the air, thus preventing corrosion.

[0126] The vent hood 342 is provided with a funnel-shaped air duct, whose cross-sectional area gradually decreases from top to bottom. The upper opening of the air duct serves as the air inlet, and the lower opening serves as the air outlet. In this embodiment, the second heating element 341 is a second heating tube. Multiple second heating tubes are provided, and these tubes are evenly arranged at the air outlet of the air duct. By providing multiple and evenly arranged second heating tubes, the second film strip can be uniformly heated, preventing uneven heating and cooling of the second film strip. The second heating tubes are positioned at the air outlet of the air duct. During heating, a certain flow of air can flow into the air duct. The air heated by the second heating tubes is then blown toward the second film strip. Heat from the second heating tubes is transferred to the second film strip not only through thermal radiation but also through heat conduction from the air. This allows for rapid heating of the second film strip, reducing heating time and improving heating efficiency. Furthermore, after the device is shut down, the air in the air duct cools the second heating tubes.

[0127] In another embodiment, the second heating element 341 may also use a PTC heater.

[0128] Reference Figure 15 、 Figure 21 and Figure 22 , Figure 21 yes Figure 1 Axonometric view of the laminating device 350, the cutting device 370 and part of the frame 500, Figure 22 yes Figure 1Exploded view of the laminating device 350, the cutting device 370 and part of the frame 500. The cutting device 370 can cut the second film strip. The laminating device 350 can make the cut second film strip close to the first film strip, thereby completing the laminating. Specifically, the laminating device 350 includes a sixteenth driving device, a first clamping member 352, a second clamping member 353 and a seventeenth driving device. The first clamping member 352 is located above the second clamping member 353. The first clamping member 352 can be close to the second clamping member 353 to complete the clamping of the second film strip. The first clamping member 352 and the second clamping member 353 can also move downward together, so that the second film strip is close to the first film strip.

[0129] In this embodiment, in order to consider the issue of space utilization, the first clamping member 352 is arranged on the output end of the sixteenth driving device, and the sixteenth driving device alone drives the first clamping member 352 to move upward or downward, and the second clamping member 353 is arranged on the output end of the seventeenth driving device, and the seventeenth driving device alone drives the second clamping member 353 to move upward or downward.

[0130] The sixteenth driving device is the fifth cylinder. The fifth cylinder body of the fifth cylinder is fixed to the frame 500 by screws. The first clamping member 352 is fixed to the fifth piston rod of the fifth cylinder. Under the action of the fifth cylinder, the first clamping member 352 will move up or down. The seventeenth driving device includes a sleeve, an optical axis 354, a second mounting bracket 355, an eighth motor 356 and a second screw nut assembly 357. The sleeve is fixed to the support plate 515 of the frame 500 (refer to Figure 15 ), the optical axis 354 is passed through the shaft sleeve and slidably fits with the shaft sleeve. The length direction of the optical axis 354 is set in the up-down direction, and the optical axis 354 and the shaft sleeve are set in four groups. The upper end of the optical axis 354 is fixed with the second clamping member 353 by screw locking, and the lower end of the optical axis 354 is fixed with the second mounting bracket 355 by screw locking. The second screw nut assembly 357 includes a second screw and a second nut, and the second screw and the second nut are threadedly fitted. The second nut is fixed on the second mounting bracket 355, and the second screw is rotatably connected to the frame 500 (achieved by a bearing). The lower end of the second screw is also connected to the rotating shaft of the eighth motor 356 through a synchronous belt and a synchronous wheel. Therefore, after the eighth motor 356 is energized, the second screw will drive the second nut to move in the up-down direction, and the second nut will transmit the motion to the second clamping member 353 through the second mounting bracket 355 and the optical axis 354, that is, the second clamping member 353 will move in the up-down direction.

[0131] In another embodiment, the sixteenth driving device may also be arranged on the output end of the seventeenth driving device, the sixteenth driving device is responsible for moving the first frame close to the second frame, and the seventeenth driving device is responsible for moving the first frame and the second frame downward together.

[0132] In another embodiment, the seventeenth driving device may also use a cylinder, and the sixteenth driving device may use a combination of a motor and a lead screw nut assembly.

[0133] To facilitate clamping the second film strip, the first clamping member 352 is a first frame, and the second clamping member 353 is a second frame, and the first frame and the second frame are both rectangular. The first frame includes a first side and a second side that are opposite to each other, and the second frame includes a third side and a fourth side that are opposite to each other. When the first frame and the second frame are fitted together, the first side and the third side abut against each other, and the second side and the fourth side abut against each other, that is, the first side and the third side can clamp one end of the second film strip, and the second side and the fourth side can clamp the other end of the second film strip, thereby completing the clamping of the second film strip. In addition, since the first frame is hollow inside, the second frame also has a hole inside, that is, the first frame and the second frame can avoid the stacked PCBs placed on the first film strip, avoiding collision between the first frame and the second frame and the PCBs.

[0134] In another embodiment, the first clamping member 352 and the second clamping member 353 may both be circular rings, and a portion of the two circular rings clamps the second film strip.

[0135] To disconnect the second film strip, a cutting device 370 is provided. The cutting device 370 includes a bracket 371 and a first heating element 372. The first heating element 372 is a first heating tube. Two brackets 371 are provided. One end of the bracket 371 is provided with an arc groove. The other end of the bracket 371 is fixed to the first side of the first frame. The two brackets 371 are spaced apart. The first heating tube is placed in the arc groove at one end of the bracket 371. The first heating tube is in a straight line. The distance between the first heating tube and the second frame is smaller than the distance between the first frame and the second frame. That is, when the first frame approaches the second frame, the first heating tube will first touch the second film strip. The high surface temperature of the first heating tube can melt the second film strip.

[0136] In another embodiment, the cutting device 370 may be a cutter. The cutter includes a first blade and a second blade. The first blade is fixed to a first side of the first frame, and the second blade is fixed to a third side of the second frame. As the first frame approaches the second frame, the first and second blades cooperate to cut the second film strip.

[0137] In summary, refer to Figures 15 to 22First, the third conveyor belt 322 rotates, assisting the first film strip in moving onto the third conveyor belt 322 (the first film strip can also provide additional traction). One or more stacked PCBs are placed on the first film strip. Simultaneously, under the action of the fourth drive mechanism, the first cylinder jaw 336 moves rightward, guiding the second film strip from the second feed roller 333 and bringing it close to the second cylinder jaw 337. The second cylinder jaw 337 then clamps one end of the second film strip. The first cylinder jaw 336 then moves leftward, returning to its original position and re-clamping the second film strip. Next, under the action of the sixteenth and seventeenth drive mechanisms, the first and second frames approach each other, clamping the second film strip. As the first frame approaches the second frame, the first heating tube fuses the second film strip. After the heating mechanism 340 heats the second film strip, the first and second frames, carrying the second film strip, approach the first film strip. The negative pressure mechanism 360 extracts the air between the second and first film strips, forcing the second film strip to adhere tightly to the first film strip. Finally, the third conveyor belt 322 rotates to carry out the packaged PCBs.

[0138] Reference Figure 23 , Figure 23 yes Figure 1 Axonometric view of cutting device 400. Cutting device 400 includes a third loading platform 420 and a cutting assembly 430, both mounted on frame 500. Third loading platform 420 is used to place multiple sets of PCBs wrapped in first and second film bags. Cutting assembly 430 cuts the first and second film bags, thereby separating a single piece of the first and second film bags (which are still adhered) into multiple pieces. A single piece of the first and second film bags wraps a set of PCBs.

[0139] Reference Figure 23 and Figure 24 , Figure 24 yes Figure 1 The third loading platform 420 includes a fourth conveyor belt 421, a seventh roller 422, an eighteenth driving device 423 and an eighth roller 424. The frame 500 also includes a third rectangular frame 516, a fifth support rod 517 and a sixth support rod 518 (see FIG. Figures 23 to 25), the seventh roller 422 and the eighth roller 424 are arranged in parallel, with the eighth roller 424 located to the right of the seventh roller 422. The front end of the seventh roller 422 is rotatably connected to the front side of the third rectangular frame 516, and the rear end of the seventh roller 422 is rotatably connected to the rear side of the third rectangular frame 516. The same applies to the eighth roller 424. The fourth conveyor belt 421 is mounted on the seventh roller 422 and the eighth roller 424, and the seventh roller 422 and the eighth roller 424 tighten the fourth conveyor belt 421. As a result, a third working surface 445 is formed on the upper surface of the fourth conveyor belt 421. The eighteenth driving device 423 is used to drive the fourth conveyor belt 421 to rotate, thereby facilitating the PCBs wrapped in the first and second film bags to enter the third working surface 445, and to unload the cut first and second film bags.

[0140] The eighteenth drive device 423 includes a ninth motor 441, a fourth synchronous gear 442, a second synchronous belt 443, and a third synchronous gear 444. The rotating shaft of the ninth motor 441 is fixedly connected to the input shaft of the reducer (via a coupling), the output shaft of the reducer is fixedly connected to the third synchronous gear 444 (via a key and set screw), the fourth synchronous gear 442 is fixedly connected to the front end of the seventh roller 422 (via a key and set screw), and the second synchronous belt 443 is sleeved over the third synchronous gear 444 and the fourth synchronous gear 442. The teeth on the inner annular surface of the second synchronous belt 443 mesh with the teeth on the outer circumferential surface of the third synchronous gear 444 and the teeth on the outer circumferential surface of the fourth synchronous gear 442. Therefore, when the ninth motor 441 is energized, the rotating shaft of the ninth motor 441 drives the seventh roller 422 to rotate via the third synchronous gear 444, the second synchronous belt 443, and the fourth synchronous gear 442, ultimately driving the fourth conveyor belt 421 to rotate.

[0141] Reference Figure 23 、 Figure 25 、 Figure 26 and Figure 27 , Figure 25 yes Figure 1 Exploded view of the fifth driving device 431, Figure 26 yes Figure 1 An exploded view of the middle section cut assembly 430, Figure 27 yes Figure 1 A top view of the middle clamping block 475. The cutting assembly 430 includes a fifth drive 431, a sixth drive 432, a seventh drive 433, a first adjustment device 434, a first cutter 435, a second adjustment device 436, and a second cutter 437. The sixth drive 432 and the seventh drive 433 are both mounted on the output end of the fifth drive 431. The first cutter 435 is mounted on the output end of the sixth drive 432 via the first adjustment device 434, and the second cutter 437 is mounted on the output end of the seventh drive 433 via the second adjustment device 436.

[0142] The fifth drive device 431 is used to drive the first cutter 435 to move in the front-to-back direction and in the left-to-right direction. The first cutter 435 moves in the front-to-back direction to cut the first and second film bags, and the first cutter 435 moves in the left-to-right direction to change the cutting path. The fifth drive device 431 can also drive the second cutter 437 to move in the front-to-back direction and in the left-to-right direction. Similarly, the second cutter 437 moves in the left-to-right direction to cut the first and second film bags, and the second cutter 437 moves in the front-to-back direction to change the cutting path.

[0143] In another embodiment, the first cutter 435 may be moved in the left-right direction to cut the first film bag and the second film bag, while the second cutter 437 may be moved in the front-back direction to cut the first film bag and the second film bag.

[0144] The sixth drive mechanism 432 is used to drive the first cutter 435 in vertical motion. The first cutter 435 moves downward, contacting the first and second film bags on the third working surface 445 to initiate cutting. The first cutter 435 moves upward, moving away from the first and second film bags on the third working surface 445 to complete cutting. Similarly, the seventh drive mechanism 433 is used to drive the second cutter 437 in vertical motion. The second cutter 437 moves downward, contacting the first and second film bags on the third working surface 445 to initiate cutting. The second cutter 437 moves upward, moving away from the first and second film bags on the third working surface 445 to complete cutting.

[0145] The first adjusting device 434 is used to adjust the cutting angle and the extension length of the first cutter 435. Similarly, the second adjusting device 436 is used to adjust the cutting angle and the extension length of the second cutter 437.

[0146] Reference Figure 27 The fifth drive device 431 includes a third drive assembly 451 and a fourth drive assembly 452. The fourth drive assembly 452 is disposed at the output end of the third drive assembly 451. The third drive assembly 451 is used to drive the first cutter 435 and the second cutter 437 to move in the left-right direction, and the fourth drive assembly 452 is used to drive the first cutter 435 and the second cutter 437 to move in the front-back direction.

[0147] The third drive assembly 451 includes a fifth synchronous wheel 461, a third synchronous belt 462, a sixth synchronous wheel 463, a tenth motor 464, a first synchronous wheel assembly 465, a first synchronous belt 466, a fifth slide 467, a second synchronous wheel assembly 468, and a second connecting shaft 469. Two fifth support rods 517 are provided, and the two fifth support rods 517 are arranged in parallel and spaced apart, with the length direction of the fifth support rods 517 extending in the left-right direction. Two first synchronous wheel assemblies 465, first synchronous belt 466, fifth slide 467, and second synchronous wheel assemblies 468 are provided, respectively. One first synchronous wheel assembly 465, one first synchronous belt 466, one fifth slide 467, and one second synchronous wheel assembly 468 are provided on the front side of the fifth support rod 517, and the remaining ones are provided on the rear side of the fifth support rod 517.

[0148] The fifth support rod 517 is an aluminum profile. A fourth channel is provided in the fifth support rod 517 in the left-right direction. The lower half of the first synchronous belt 466 is located in the fourth channel of the fifth support rod 517, and the upper half of the first synchronous belt 466 is located above the fifth support rod 517. The first synchronous pulley assembly 465 is provided at the right end of the fifth support rod 517, and the second synchronous pulley assembly 468 is provided at the left end of the fifth support rod 517.

[0149] The first synchronous wheel assembly 465 includes a first synchronous wheel and a first housing. The first synchronous wheel is located within the first housing and is rotatably connected to the first housing. The first housing is screwed to the right end of the fifth support rod 517. Similarly, the second synchronous wheel assembly 468 includes a second synchronous wheel and a second housing. The second synchronous wheel is located within the second housing and is rotatably connected to the second housing. The second housing is screwed to the left end of the fifth support rod 517.

[0150] The first synchronous belt 466 is mounted on the first and second synchronous pulleys, and the fifth slide 467 is secured to the first synchronous belt 466 via fasteners. The rotating shaft of the tenth motor 464 is fixedly connected to the fifth synchronous pulley 461 (via an expansion sleeve), and the sixth synchronous pulley 463 is fixedly connected to the first synchronous pulley located on the front fifth support rod 517 (via an expansion sleeve). The third synchronous belt 462 is mounted on the fifth and sixth synchronous pulleys 461, 463. The two first synchronous pulleys are fixedly connected via a second connecting shaft 469 and a coupling. As a result, when power is supplied to the tenth motor 464, the two first synchronous belts 466 rotate synchronously.

[0151] The structure of the fourth drive assembly 452 is similar to that of the third drive assembly 451. It includes a seventh synchronous wheel, a fourth synchronous belt, an eighth synchronous wheel, an eleventh motor, a third synchronous wheel assembly, a fifth synchronous belt, a sixth slide, and a fourth synchronous wheel assembly. A sixth support rod 518 is provided, its length extending in the front-to-back direction. The ends of the sixth support rod 518 are respectively fixed to the two fifth slides 467 (secured by screws). One third synchronous wheel assembly, one fifth synchronous belt, one sixth slide, and one fourth synchronous wheel assembly are each provided. The third synchronous wheel assembly is located at the front end of the sixth support rod 518, and the fourth synchronous wheel assembly is located at the rear end of the sixth support rod 518. The third synchronous wheel assembly includes a ninth synchronous wheel and a third housing. The fourth synchronous wheel assembly includes a tenth synchronous wheel and a fourth housing. The fifth synchronous belt is mounted on the ninth and tenth synchronous wheels. The sixth slide is secured to the fifth synchronous belt (secured by fasteners). The eleventh motor drives the ninth synchronous wheel to rotate via the seventh synchronous wheel, the fourth synchronous belt, and the eighth synchronous wheel, which in turn drives the fifth synchronous belt to rotate.

[0152] In another embodiment, the third driving assembly 451 and the fourth driving assembly 452 can be replaced by a combination of a motor, a lead screw and a nut.

[0153] Reference Figure 26 The sixth drive device 432 includes a sixth cylinder 471, a fourth sliding assembly, and a third mounting seat 474. The fourth sliding assembly includes a fourth slider 472 and a fourth slide rail 473. The cylinder body of the sixth cylinder 471 is fixed to the sixth slide. One end of the fourth slide rail 473 is fixedly connected to the first piston rod of the sixth cylinder 471 (via a threaded connection). The other end of the fourth slide rail 473 is inserted into the third mounting seat 474 and secured by a set screw. The fourth slider 472 is slidably connected to the fourth slide rail 473, and the fourth slider 472 is also fixed to the sixth slide. As a result, driven by the sixth cylinder 471, the first cutter 435 will move in the vertical direction. Because the fourth slide rail 473 moves up and down, the first cutter 435 has a longer travel, allowing the first cutter 435 to extend between the two sets of PCBs and cut the first and second film bags.

[0154] In another embodiment, the sixth driving device 432 may be replaced by a linear motor.

[0155] The first adjustment device 434 includes a clamping block 475, an adjustment block 476, and screws. The lower end of the clamping block 475 is provided with two mounting holes 485. Two third screws, inserted through the two mounting holes 485, secure the clamping block 475 to the third mounting base 474. A first adjustment hole 484 is provided in the center of the clamping block 475. A notch 482 is formed in the sidewall of the first adjustment hole 484. A threaded hole 483 and a first through-hole 481 are provided on either side of the notch 482. An adjustment shaft 478 is provided on the right side of the adjustment block 476. The adjustment shaft 478 is inserted into the first adjustment hole 484. The screw, inserted through the first through-hole 481, engages with the threaded hole 483. The first cutter 435 is fixed to the clamping block 475. This allows the first cutter 435 to rotate about its left-right axis, and the angle between the first cutter 435 and the third working surface 445 is adjustable. When the angle between the first cutter 435 and the third working surface 445 is small, the length of the blade of the first cutter 435 that can contact the first membrane bag and the second membrane bag is longer, and the cutting is smoother and more stable; when the angle between the first cutter 435 and the third working surface 445 is large, the length of the blade of the first cutter 435 that can contact the first membrane bag and the second membrane bag is shorter, and the cutting is faster.

[0156] To adjust the extension length of the first cutter 435, an adjustment block 476 is provided with an obliquely cut slot 477, into which the handle of the first cutter 435 is placed. The adjustment block 476 is also provided with a set screw, the end of which extends into the slot 477 and abuts against the handle of the first cutter 435, thereby achieving detachable fastening of the first cutter 435 to the adjustment block 476. Therefore, when the extension length of the first cutter 435 needs to be adjusted, the set screw is loosened, and the end of the set screw disengages from the handle of the first cutter 435, allowing the adjustment block 476 to slide along the slot 477 until the extension length of the first cutter 435 meets the required value. The set screw is then tightened again to complete the adjustment of the extension length of the first cutter 435.

[0157] The structure of the seventh driving device 433 is exactly the same as that of the sixth driving device 432, and the structure of the second adjusting device 436 is exactly the same as that of the first adjusting device 434. Only the orientation of the second cutter 437 is different from that of the first cutter 435, which will not be repeated here.

[0158] In summary, by providing the fifth and sixth drive devices 431 and 432, the first cutter 435 can cut the first and second film bags multiple times in the front-to-back direction. The fifth and seventh drive devices 431 and 433 can cause the second cutter 437 to cut the first and second film bags multiple times in the left-to-right direction, thereby dividing the first and second film bags into multiple pieces based on the positions of each group of PCBs, thereby separating each group of PCBs. The first adjustment device 434 can adjust the angle between the first cutter 435 and the third working surface 445, as well as the extension length of the first cutter 435. The second adjustment device 436 can adjust the angle between the second cutter 437 and the third working surface 445, as well as the extension length of the second cutter 437.
