[0071] Please also see Figure 1 and Figure 2One embodiment of the present invention provides an automatic product packaging system, comprising:

[0072] A loading device 100 for conveying and positioning a packaging box 700 in a folded state;

[0073] A box sealing device 200 for driving the inner flap 710 and the outer flap 720 of the packaging box 700 in the unfolded state to flip over so that the inner flap 710 and the outer flap 720 close the opening of the storage cavity of the packaging box 700;

[0074] A box packing device 300 for packing the product 600 into the receiving cavity of the packaging box 700;

[0075] A material unloading device 500 for conveying a packaging box 700 in which the product 600 has been packaged;

[0076] And, a packaging box transfer device 400 is used to grab the packaging box 700, drive the packaging box 700 from a folded state to an unfolded state, and move the packaging box 700 in the unfolded state between the loading device 100, the sealing device 200, the packing device 300 and the unloading device 500.

[0077] The packaging box 700 is initially in a folded state. After it is placed on the loading device 100, the loading device 100 transports the folded packaging box 700 to the vicinity of the packaging box transfer device 400 and positions the packaging box 700 so that the packaging box transfer device 400 can accurately grasp the appropriate position of the packaging box 700. Then the packaging box transfer device 400 unfolds the packaging box 700, so that the packaging box 700 is in an unfolded state. At this time, the packaging box 700 forms a storage cavity, and at least one end of the storage cavity has an opening. Two opposite inner swing covers 710 and two opposite outer swing covers 720 are arranged around the opening. In this embodiment, the storage cavity is described as having openings at both ends. The packaging box transferring device 400 first moves the packaging box 700 in the unfolded state to the sealing device 200, so that the inner flap 710 and the outer flap 720 of the packaging box 700 at one end of the storage cavity are flipped to close the opening of the storage cavity, so that only one opening of the storage cavity is open at this time. Then, the packaging box transferring device 400 moves the packaging box 700 to the packing device 300, so that the product 600 is loaded into the packaging box 700. Then, the packaging box transferring device 400 moves the packaging box 700 to the sealing device 200 again, so that the inner flap 710 and the outer flap 720 at the other end of the storage cavity close the opening of the storage cavity, thereby achieving complete closure of the storage cavity. At this point, the packaging box 700 completes the packaging of the product 600. Finally, the packaging box transferring device 400 places the packaging box 700 that has completed packaging of the product 600 on the unloading device 500, and the unloading device 500 transports the packaging box 700 to a storage location or other suitable location.

[0078] Of course, other suitable packaging methods can also be adopted for other types of packaging boxes 700. For example, when the storage cavity has an opening at only one end, the packaging box 700 can first be sent to the packing device 300 for packing the product 600, and then sent to the sealing device 200 for sealing.

[0079] See also Figure 3 In some optional embodiments, the loading device 100 includes: a frame 110, a package box picking component 120 and a positioning frame 130.

[0080] The packaging box picking assembly 120 is disposed on the frame 110 and is used to pick up the packaging box 700 and can be close to or away from the positioning frame 130;

[0081] See also Figure 3 The positioning frame 130 includes an inclined bottom plate 131, a first positioning member 132 and a second positioning member 133. The first positioning member 132 and the second positioning member 133 are arranged on the inclined bottom plate 131. The inclined bottom plate 131 extends toward the first positioning member 132 and the second positioning member 133 in the direction from top to bottom. The first positioning member 132 and the second positioning member 133 are used to respectively position and cooperate with the adjacent two sides of the packaging box 700.

[0082] It should be noted that the package box 700 picked up by the package box picking assembly 120 is in a folded, flat, rectangular state. The package box picking assembly 120 grabs the package box 700 and places it on the inclined bottom plate 131. The package box 700 then slides along the inclined bottom plate 131 toward the first positioning member 132 and the second positioning member 133. The first positioning member 132 and the second positioning member 133 position the adjacent two sides of the package box 700, thereby positioning the package box 700 and facilitating subsequent grabbing of the package box 700. Among them, based on the position of the first positioning member 132, the position of the second positioning member 133 and the size of the packaging box 700 that can be known in advance, after the packaging box 700 is positioned, the position of any position on the packaging box 700 relative to the first positioning member 132 and the second positioning member 133 can be inferred. For example, the first positioning member 132 is equivalent to the first coordinate axis located on the top surface of the inclined bottom plate 131, and the second positioning member 133 is equivalent to the second coordinate axis located on the top surface of the inclined bottom plate 131. Both sides of the packaging box 700 are flush with the first coordinate axis and the second coordinate axis. Therefore, it is easy to infer the coordinates of any position on the packaging box 700, thereby facilitating the packaging box picking component 120 to grab the packaging box 700.

[0083] See also Figure 4In some optional embodiments, the loading device 100 of the carton sealing equipment also includes a packaging box storage rack 140, and multiple packaging boxes 700 can be stacked on the packaging box storage rack 140 from top to bottom. The packaging box storage rack 140 is set on one side of the positioning rack 130, and the packaging box picking assembly 120 moves between the positioning rack 130 and the packaging box storage rack 140, thereby transporting the packaging boxes 700 stored on the packaging box storage rack 140 to the positioning rack 130.

[0084] In some optional embodiments, a third positioning member 141 and a fourth positioning member 142 are provided on the package box storage rack 140. The third positioning member 141 and the fourth positioning member 142 are used to respectively position and cooperate with the adjacent two sides of the package box 700. The packages 700 stacked on the package box storage rack 140 abut against the third positioning member 141 and the fourth positioning member 142, thereby facilitating the positioning of the package box 700, so that the package box picking component 120 can accurately pick up the package box 700.

[0085] The specific structure of the package box picking assembly 120 can be designed according to actual needs. For example, in some optional embodiments, the package box picking assembly 120 includes a picking drive module 121 and a clamping module 122. The picking drive module 121 is set on the frame 110 and is connected to the clamping module 122 for driving the clamping module 122 to move closer to or away from the positioning frame 130. The clamping module 122 is used to clamp the package box 700. The picking drive module 121 of the package box picking assembly 120 can drive the clamping module 122 to move between the positioning frame 130 and the package box storage rack 140.

[0086] See also Figure 5 The specific structure of the clamping module 122 can be designed according to actual needs. For example, in some optional embodiments, the clamping module 122 includes a mounting frame 1221 and a plurality of vacuum suction cups 1222. The mounting frame 1221 is connected to the pickup drive module 121. The plurality of vacuum suction cups 1222 are evenly arranged on the mounting frame 1221. The vacuum suction cups 1222 are connected to a negative pressure generating device so that the vacuum suction cups 1222 generate negative pressure, and the packaging box 700 is vacuum-adsorbed by the vacuum suction cups 1222, thereby enabling the clamping module 122 to clamp the packaging box 700. Of course, the clamping module 122 can also adopt other suitable structures. For example, the clamping module 122 includes a plurality of finger cylinders, and the plurality of finger cylinders clamp the packaging box 700.

[0087] In some optional embodiments, the vacuum suction cup 1222 is provided with an adjustment rod 1223, which is movably mounted on the mounting frame 1221 and can move up and down relative to the mounting frame 1221. The adjustment rod 1223 is movably provided with an upper clamping block 1224 and a lower clamping block 1225. After the adjustment rod 1223 is adjusted to a desired vertical position relative to the mounting frame 1221, the upper clamping block 1224 and the lower clamping block 1225 cooperate to clamp the mounting frame 1221 to lock the adjustment rod 1223. In this embodiment, the adjustment rod 1223 is a screw, and the upper clamping block 1224 and the lower clamping block 1225 are nuts.

[0088] In some optional embodiments, a horizontal adjustment slot 1226 is provided on the mounting frame 1221, and the adjustment rod 1223 can move along the horizontal adjustment slot 1226. The adjustment rod 1223 can move up and down along the axis of the adjustment rod 1223 relative to the horizontal adjustment slot 1226, and can also move along the horizontal adjustment slot 1226. After adjusting the upper and lower positions and horizontal positions of the adjustment rod 1223, the mounting frame 1221 is clamped by the upper clamping block 1224 and the lower clamping block 1225.

[0089] See also Figure 6 In some optional embodiments, the picking drive module 121 includes a lateral translation drive mechanism 1211, a movable frame 1212 and an up and down translation drive mechanism 1213. The lateral translation drive mechanism 1211 is set on the frame 110 and is driven by the movable frame 1212. The up and down translation drive mechanism 1213 is set on the movable frame 1212 and is driven by the clamping module 122. The lateral translation drive mechanism 1211 can drive the movable frame 1212 to move between the positioning frame 130 and the packaging box storage rack 140. After the movable frame 1212 moves to above the positioning frame 130 or the packaging box storage rack 140, the up and down translation drive mechanism 1213 drives the clamping module 122 to descend, thereby clamping or putting down the packaging box 700.

[0090] The specific structures of the lateral translation drive mechanism 1211 and the vertical translation drive mechanism 1213 can be designed according to actual needs. For example, the lateral translation drive mechanism 1211 and the vertical translation drive mechanism 1213 can adopt a screw drive mechanism, a rotary motor translation drive mechanism, a belt translation drive mechanism, a cylinder translation drive mechanism, or a linear motor translation drive mechanism. In this embodiment, the lateral translation drive mechanism 1211 is a synchronous belt translation drive mechanism, and the vertical translation drive mechanism 1213 includes an upper and lower drive motor, a drive gear, and a drive rack. The upper and lower drive motors are arranged on the movable frame 1212. The upper and lower drive motors are connected to the drive gear, which is meshed with the drive rack. The drive rack is connected to the clamping module 122. The upper and lower drive motors drive the clamping module 122 to move up and down by driving the drive rack.

[0091] In some optional embodiments, a longitudinal adjustment rail 1214 and a mounting seat 1215 are provided on the movable frame 1212, and the mounting seat 1215 is movably connected to the longitudinal adjustment rail 1214. In this embodiment, the mounting seat 1215 is detachably locked with the longitudinal adjustment rail 1214 through a number of screws, and the up and down translation drive mechanism 1213 is provided on the mounting seat 1215, so as to facilitate the mounting seat 1215 to adjust its position along the longitudinal adjustment rail 1214, thereby realizing the adjustment of the longitudinal position of the clamping module 122, which is convenient for adapting to actual production conditions, for example, it can adapt to packaging boxes 700 of different sizes.

[0092] See also Figure 7 In some optional embodiments, the box sealing device 200 includes a bracket 210 and a swing cover guide mechanism 220 and a first glue sealing mechanism 230 provided on the bracket 210 .

[0093] See also Figure 8 The first sealing mechanism 230 includes an unwinding mechanism 231 for storing and unwinding the tape and a cutting mechanism 232 for cutting the tape. The unwinding mechanism 231 and the cutting mechanism 232 are arranged on the bracket 210; the swing cover guide mechanism 220 includes an inner swing cover 710 guide 221 for guiding the inner swing cover 710 of the packaging box 700 to close and an outer swing cover 720 guide 222 for guiding the outer swing cover 720 of the packaging box 700 to close. The inner swing cover 710 guide 221 and the outer swing cover 720 guide 222 are arranged in sequence in the direction close to the unwinding mechanism 231.

[0094] In this embodiment, before the packaging box 700 is sealed, the packaging box 700 is in an unfolded state, and a storage cavity is formed around the packaging box 700. The two ends of the storage cavity have openings, and two opposite inner swing covers 710 and two opposite outer swing covers 720 are formed around the openings.

[0095] See also Figures 9 to 12The packaging box 700 moves along the guide 221 of the inner flap 710 toward the guide 222 of the outer flap 720. During this process, the two inner flaps 710 gradually close toward the opening under the guidance of the inner flap 710 guide 221. Then, the packaging box 700 moves along the guide 222 of the outer flap 720 toward the unwinding mechanism 231. During this process, the two outer flaps 720 gradually close toward the opening under the guidance of the outer flap 720 guide 222 until the outer flaps 720 are stacked on the inner flap 710. The packaging box 700 then moves past the unwinding mechanism 231, causing the adhesive tape to adhere to one side of the packaging box 700, the two outer flaps 720, and the other side of the packaging box 700, thereby fixing the two outer flaps 720 toward each other. The inner flap 710 is restrained by the outer flap 720 and does not turn outward, thereby allowing the inner flap 710 and the outer flap 720 to seal the opening. According to actual needs, the first sealing mechanism 230 may be further used to bond and fix other appropriate positions of the packaging box 700.

[0096] In some optional embodiments, the guide member 221 of the inner swing cover 710 includes a first guide portion 2211 and a maintaining portion 2212. The first guide portion 2211 and the maintaining portion 2212 are arranged in sequence in a direction close to the unwinding mechanism 231. The first guide portion 2211 is arc-shaped and extends obliquely in a direction away from the maintaining portion 2212. The packaging box 700 is first rotated at a certain angle so that the inner swing cover 710 on the packaging box 700 away from the maintaining portion 2212 abuts against the first guide portion 2211. When the inner swing cover 710 on the packaging box 700 away from the maintaining portion 2212 just abuts against the maintaining portion 2212, the inner swing cover 710 on the packaging box 700 away from the maintaining portion 2212 forms an acute angle with the first guide 2211. Then, the packaging box 700 moves along the first guide portion 2211 toward the maintaining portion 2212 so that the inner swing cover 710 away from the maintaining portion 2212 gradually flips toward the opening. During this process, the inner swing cover 710 on the packaging box 700 close to the maintaining part 2212 also abuts against the first guide part 2211 or the maintaining part 2212, and then the inner swing cover 710 on the packaging box 700 close to the maintaining part 2212 moves along the first guide part 2211 or the maintaining part 2212 and gradually flips toward the opening. When the inner swing cover 710 on the packaging box 700 close to the maintaining part 2212 just abuts against the maintaining part 2212, the inner swing cover 710 on the packaging box 700 close to the maintaining part 2212 forms an acute angle with the maintaining part 2212.

[0097] See also Figure 10 and Figure 14In some optional embodiments, the guide member 222 of the outer flap 720 includes two second guide portions 2221, which gradually approach each other in the direction approaching the first sealing mechanism 230. When the packaging box 700 moves along the guide member 222 of the outer flap 720 toward the first sealing mechanism 230, the two second guide portions 2221 correspondingly flip the two outer flaps 720 toward each other, thereby guiding the outer flaps 720 to flip toward the opening. The second guide portions 2221 extend obliquely in a direction away from the unwinding mechanism 231, which facilitates the second guide portions 2221 to flip the outer flap 720 toward the opening.

[0098] In some optional embodiments, the two second guide portions 2221 are respectively arranged on both sides of the maintaining portion 2212, and gradually move away from the maintaining portion 2212 in the direction away from the unwinding mechanism 231. When the maintaining portion 2212 guides the inner swing cover 710 to fold, it can also play a role in maintaining the closed state of the inner swing cover 710, thereby avoiding the second guide portion 2221 being affected by the inner swing cover 710 when guiding the outer swing cover 720 to close.

[0099] See also Figure 7 、 Figure 15 and Figure 16 In some optional embodiments, the sealing device 200 further includes two second sealing mechanisms 240 for storing and unwinding the tape. The two second sealing mechanisms 240 are arranged side by side, with the first sealing mechanism 230 and the second sealing mechanism 240 arranged sequentially in a direction away from the guide member 222 of the outer flap 720. The first sealing mechanism 230 and the second sealing mechanism 240 both include an unwinding mechanism 231 and a cutting mechanism 232. The two second sealing mechanisms 240 can more conveniently bond the opposing sides of the outer flap 720 to the side of the packaging box 700, thereby improving the sealing stability of the packaging box 700.

[0100] See also Figure 17 In some optional embodiments, the unwinding mechanism 231 includes an unwinding module 2311, an elastic structure 2312 and a first pressure roller 2313. The unwinding module 2311 is arranged on the bracket 210, and the elastic structure 2312 is arranged on the bracket 210 and is connected to the first pressure roller 2313. The tape stored in the unwinding module 2311 is connected to the first pressure roller 2313. When the first pressure roller 2313 presses the tape toward the outer swing cover 720 on the packaging box 700 or other structures on the packaging box 700, the elastic structure 2312 produces elastic deformation. Driven by the elastic force of the elastic structure 2312, the first pressure roller 2313 can press the tape tightly against the outer swing cover 720 on the packaging box 700 or other structures on the packaging box 700, so that the tape can be firmly and tightly attached to the outer swing cover 720 on the packaging box 700 or other structures on the packaging box 700.

[0101] The specific structure of the unwinding module 2311 can be designed according to actual needs. For example, the unwinding module 2311 includes an unwinding roller, which receives the tape. The unwinding roller can adopt passive unwinding. After the tape is adhered to the packaging box 700, the movement of the packaging box 700 drives the tape to be unwound. Of course, the unwinding roller can also adopt active unwinding. The unwinding roller is connected to an unwinding motor, and the unwinding motor drives the unwinding roller to rotate to realize tape unwinding.

[0102] In some optional embodiments, the unwinding mechanism 231 further includes a second pressing roller 2314. The first pressing roller 2313 and the second pressing roller 2314 are arranged in sequence in a direction away from the guide member 222 of the outer flap 720, and the elastic structure 2312 is connected to the second pressing roller 2314. After the first pressing roller 2313 sticks the tape to the outer flap 720 or other structures on the packaging box 700, the second pressing roller 2314 is further pressed against the tape under the elastic force of the elastic structure 2312, so that the tape is more firmly attached to the outer flap 720 or other structures on the packaging box 700.

[0103] In some optional embodiments, the elastic structure 2312 includes a first rotating seat 2315, a second rotating seat 2316, a connecting rod 2317, and a spring 2318. The first rotating seat 2315 and the second rotating seat 2316 are rotatably mounted on the bracket 210. The ends of the connecting rod 2317 are rotatably connected to the first rotating seat 2315 and the second rotating seat 2316, respectively. One end of the spring 2318 is connected to the first rotating seat 2315 or the second rotating seat 2316, and the other end is connected to the bracket 210. In this embodiment, the spring 2318 is described as being connected to the second rotating seat 2316. The first pressure roller 2313 is rotatably mounted on the first rotating seat 2315, and the second pressure roller 2314 is rotatably mounted on the second rotating seat 2316. When the first pressure roller 2313 is pressed on the packaging box 700, it will drive the first rotating seat 2315 to rotate. At the same time, the first rotating seat 2315 drives the second rotating seat 2316 to rotate through the connecting rod 2317. When the second rotating seat 2316 rotates, it drives the spring 2318 to produce elastic deformation. The elastic force of the spring 2318 can drive the first rotating seat 2315 and the second rotating seat 2316 to rotate toward the packaging box 700, thereby making the first pressure roller 2313 and the second pressure roller 2314 press toward the packaging box 700.

[0104] In some optional embodiments, the cutting mechanism 232 includes a cutting tool 2321 and a tool translation drive module 2322. The tool translation drive module 2322 is set on the bracket 210 and is driven and connected to the cutting tool 2321. The tool translation drive module 2322 drives the cutting tool 2321 to press against the tape, thereby achieving cutting of the tape.

[0105] See also Figure 18 and Figure 19 In some optional embodiments, the box packing device 300 includes a box guiding mechanism 310 and a box pushing mechanism 320.

[0106] The box guide mechanism 310 includes a first base frame 311 and an introduction member 312. The first base frame 311 is provided with a guide groove 3111 for placing the product 600. The introduction member 312 is arranged on the first base frame 311 and is located at the end of the guide groove 3111; the box pushing mechanism 320 includes a box pushing drive module 321 and a box pushing member 322. The box pushing drive module 321 is driven and connected to the box pushing member 322. The box pushing member 322 is movably arranged on the first base frame 311 and is configured to move along the guide direction of the guide groove 3111 under the drive of the box pushing drive module 321.

[0107] See also Figure 20 The product 600 is placed in the guide groove 3111, and the packaging box 700 is placed at the end of the guide groove 3111, and the guide piece 312 is aligned with the storage cavity of the packaging box 700. The product 600 moves along the guide groove 3111 under the push of the box pushing piece 322, and enters the storage cavity of the packaging box 700 after passing through the guide piece, thereby realizing accurate and fast packing operation.

[0108] See also Figure 21 In some optional embodiments, the introduction member 312 includes a plurality of introduction strips 3121 arranged on the first base frame 311, and the plurality of introduction strips 3121 surround to form an introduction channel, the entrance of the introduction channel is arranged corresponding to the end of the guide groove 3111, and the introduction channel extends along the guide direction of the guide groove 3111. The introduction strip 3121 extends between the inner swing cover 710 and the outer swing cover 720 of the packaging box 700, or the introduction strip 3121 passes between the inner swing cover 710 and the outer swing cover 720, and then extends into the storage cavity of the packaging box 700. The product 600 passes through the introduction channel between multiple introduction strips 3121 under the push of the box pusher 322, and then smoothly enters the storage cavity of the packaging box 700. Due to the restriction of the guide strip, the product 600 is not easy to shift its position, and the guide strip can also maintain the position of the inner swing cover 710 and the outer swing cover 720 of the packaging box 700, preventing the inner swing cover 710 and the outer swing cover 720 from shaking toward the opening of the storage cavity and hindering the product 600 from entering the storage cavity.

[0109] In some optional embodiments, the plurality of guide bars 3121 gradually approach one another in the direction from the entrance to the exit of the guide channel, giving the guide channel a bell-mouth shape. This design allows the end of the guide bar 3121 near the exit of the guide channel to more easily extend between the inner flap 710 and the outer flap 720 of the packaging box 700, thereby reducing the accuracy of position control of the packaging box 700. The entrance of the guide channel can also be enlarged to be larger than the opening of the storage cavity, thereby facilitating the entry of the product 600 into the guide channel. The guide bars 3121 are elastic, so that after the product 600 enters the guide channel, if the width of the product 600 is relatively small, the plurality of guide bars 3121 can be stretched apart, thereby preventing the guide bars 3121 from obstructing the product 600 from passing through the guide channel.

[0110] In some optional embodiments, the guide member 312 further includes a mounting bar, a mounting ring 3122 disposed on the first chassis 311 and arranged around the end of the guide slot 3111, and at least one guide bar 3121 is mounted on the mounting ring 3122. The mounting ring 3122 not only facilitates the installation of the guide bar 3121, but also serves to block and restrict the packaging box 700 when the packaging box 700 is aligned with the guide member 312 so that the guide bar 3121 extends into the packaging box 700.

[0111] See also Figure 22 In some optional embodiments, multiple side guide rollers 3112 are rotatably mounted on both sides of the guide groove 3111. Multiple side guide rollers 3112 on the same side are sequentially arranged along the guide direction of the guide groove 3111. The side guide rollers 3112 can improve the smooth movement of the product 600. Furthermore, rolling friction is generated between the side guide rollers 3112 and the product 600, which helps reduce friction between the product 600 and the guide groove 3111, thereby preventing wear on the product 600.

[0112] In some optional embodiments, a plurality of bottom guide rollers 3113 are rotatably disposed at the bottom of the guide groove 3111, and the bottom guide rollers 3113 are sequentially arranged along the guide direction of the guide groove 3111. The bottom guide rollers 3113 can improve the smooth movement of the product 600, and the rolling friction between the bottom guide rollers 3113 and the product 600 helps reduce friction between the product 600 and the guide groove 3111, thereby preventing wear on the product 600.

[0113] In order to facilitate driving the box pushing member 322, in some optional embodiments, the box pushing member 322 is connected to the box pushing drive module 321 through two transmission connecting members 323, and the two transmission connecting members 323 are respectively located on both sides of the bottom guide box roller 3113.

[0114] The specific structure of the push-box drive module 321 can be designed based on actual needs. For example, the push-box drive module 321 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module. In this embodiment, the push-box drive module 321 is a synchronous belt drive module. The synchronous belt of the synchronous belt drive module is connected to the two transmission connectors 323 via a transmission block, thereby enabling the synchronous belt drive module to drive the pusher to move.

[0115] In order to facilitate the conveying of the product 600 into the guide groove 3111 and improve the degree of automation, in some optional embodiments, the packing device 300 also includes a product 600 conveying mechanism 330, which is arranged on one side of the first base frame 311, and the conveying direction of the product 600 conveying mechanism 330 is toward the guide groove 3111.

[0116] The specific structure of the product 600 conveying mechanism 330 can be designed according to actual needs. For example, in some optional embodiments, the product 600 conveying mechanism 330 includes a conveyor belt module 331, a second base frame 332 and a lifting module 333. The lifting module 333 is driven and connected to the conveyor belt module 331. The conveyor belt module 331 is rotatably set on the second base frame 332. The conveyor belt module 331 is configured to rotate upward under the drive of the lifting module 333. The conveyor belt module 331 tilts toward the guide groove 3111, so that the product 600 can rely on its own gravity to assist in moving toward the guide groove 3111. Combined with the conveying of the conveyor belt module 331, the product 600 can quickly enter the guide groove 3111.

[0117] The specific structure of the lifting module 333 can be designed according to actual needs. For example, the lifting module 333 is a cylinder, an electric cylinder or a hydraulic cylinder. The lifting module 333 rotates with the second base frame 332, and the output end of the lifting module 333 rotates with the bottom of the conveyor belt module 331.

[0118] Of course, the product 600 conveying mechanism 330 can also adopt a mesh belt and mesh chain conveying mechanism, a roller conveying mechanism or a chain plate conveying mechanism, etc., without limitation to this example.

[0119] The unloading device 500 can adopt a structure similar to the product 600 conveying mechanism 330. After the conveyor belt module 331 of the unloading device 500 is lifted and tilted, it can be tilted toward the storage position or other suitable positions to facilitate the transportation of the packaging box 700 of the completed product 600 to the storage position or other suitable positions.

The first suction mechanism 424 is disposed on the first base 421, and the second suction mechanism 425 is disposed on the second base 422. The first suction mechanism 424 and the second suction mechanism 425 are configured to respectively suction adjacent sides of the packaging box 700. The first base 421 and the second base 422 rotate relative to each other to a gripping position and an unfolded position. When the first base 421 and the second base 422 rotate relative to each other to the unfolded position, the first base 421 and the second base 422 drive the packaging box 700 to expand from a folded state to an unfolded state.

[0123] See also Figure 2 Before the packaging box 700 is grabbed, the packaging box 700 is in a folded state, and the angle between the adjacent two sides of the packaging box 700 is approximately 180 degrees. At this time, the first base 421 and the second base 422 rotate relative to each other to the grabbing position, so that the first adsorption mechanism 424 and the second adsorption mechanism 425 can be correspondingly adsorbed on the adjacent two sides of the packaging box 700, and then the first base 421 and the second base 422 rotate toward each other until they are rotated to the unfolded position. At this time, the angle between the adjacent two sides of the packaging box 700 is approximately 90 degrees. At this time, the packaging box 700 is in an unfolded state, so that a storage cavity for accommodating the product 600 is formed in the packaging box 700.

[0124] See also Figure 25 The specific structure of the first adsorption mechanism 424 can be designed according to actual needs. For example, in some optional embodiments, the first adsorption mechanism 424 includes a plurality of first suction cups 4241, which are evenly arranged on the first base 421. The first suction cups 4241 generate negative pressure to adhere to the surface of the packaging box 700. Of course, the first adsorption mechanism 424 can also adopt other suitable adsorption structures, not limited to suction cups. For example, the first adsorption mechanism 424 only includes a plurality of adsorption holes.

[0125] In order to facilitate the connection of the first suction cup 4241 with the negative pressure generating device, thereby facilitating the first suction cup 4241 to generate negative pressure, in some optional embodiments, the first adsorption mechanism 424 also includes a plurality of first air guide strips 4242 arranged side by side on the first base 421, and each first air guide strip 4242 is provided with a plurality of first suction cups 4241 arranged in sequence along the extension direction of the first air guide strip 4242, and a first air cavity connected to the first suction cup 4241 is provided in the first air guide strip 4242, and the first air cavity is conducive to balancing the negative pressure of each first suction cup 4241.

The second suction cups 4251 generate negative pressure to adhere to the surface of the packaging box 700. Of course, the second adsorption mechanism 425 can also adopt other suitable adsorption structures, not limited to suction cups. For example, the second adsorption mechanism 425 may only include a plurality of adsorption holes.

Each second air guide strip 4252 is provided with a plurality of second suction cups 4251 arranged sequentially along the extension direction of the second air guide strip 4252. The second air guide strip 4252 is provided with a second air cavity in communication with the second suction cup 4251. The second air cavity facilitates equalizing the negative pressure of each second suction cup 4251. The first suction cup 4241, the second suction cup 4251, and the vacuum suction cup 1222 can be connected to the same negative pressure generating device, and the negative pressure can be provided by the same negative pressure generating device; of course, the first suction cup 4241, the second suction cup 4251, and the vacuum suction cup 1222 can also be connected to different negative pressure generating devices.

[0128] See also Figure 26The rotation drive mechanism 423 can drive the first base 421 to rotate relative to the second base 422 or drive the second base 422 to rotate relative to the first base 421. Alternatively, the rotation drive mechanism 423 can also drive the first base 421 and the second base 422 to rotate relative to each other at the same time. The specific structure of the rotation drive mechanism 423 can be designed according to actual needs.
