[0044] The transmission assembly 10 includes a conveyor belt 100 and a first motor 101 . The first motor 101 drives the conveyor belt 100 . The transmission assembly 10 is arranged on the frame 6 along the Y-axis.

[0045] The rack 6 is provided with an electrical cabinet 61, and the controller 60 is installed in the electrical cabinet 61. The controller 60 is electrically connected to the first motor 101 and controls the first motor 101 to rotate, and the first motor 101 drives the conveyor belt 100 to move, and the inner box 199 is transported along the Y axis.

[0046] The push assembly 11 includes a first push plate 110, a first cylinder 111 and a fixed component 12. The first cylinder 111 drives the first push plate 110 to move, wherein the first cylinder 111 is fixedly connected to the fixed component 12, the fixed component 12 is arranged on the frame 6, and the first cylinder 111 moves along the X-axis. Specifically, the fixed component 12 includes a first fixed plate 120, a second fixed plate 121, a first pad plate 122 and a reinforcing rib 123. A through hole is provided on the first fixed plate 120, and the first cylinder 111 passes through the through hole and is fixedly connected to the first push plate 110 by a nut.

[0048] The push assembly 11 further includes a pair of guide rods 112, which are fixedly connected to the first push plate 110. By providing a pair of guide rods 112, the movement of the first cylinder 111 is smoother, and the movement of the first push plate 110 is not biased, thereby ensuring that the push assembly 11 pushes the inner box more smoothly.

[0049] The guide plate group 13 includes a first guide plate 130, a second guide plate 132 and a table panel 133 supporting the inner box 199.

The table panel 133 is disposed on the frame 6. The first guide plate 130 and the second guide plate 132 are both parallel to the X axis, and the distance between them is equal to a multiple of the length of the inner box 199. They guide and regularize the multiple inner boxes 199. In this embodiment, the distance between the first guide plate 130 and the second guide plate 132 is equal to the length of the two inner boxes 199. The length of the second guide plate 132 is greater than that of the first guide plate 130, and the second guide plate 132 is fixedly connected to the table panel 133 by screws. The first guide plate 130 spans over the transmission assembly 10, a portion of which is fixedly connected to the table panel 133 by screws, and another portion is provided with a groove 131.

The first guide plate 130 and the second guide plate 132 are parallel, and the distance between them is a multiple of the length of the inner box 199. All the inner boxes 199 pushed by the pushing component 11 can run smoothly and regularly between the first guide plate 130 and the second guide plate 132, ensuring the regular operation of the subsequent adsorption work.

[0050] The first guide plate 130 is also provided with a first photoelectric sensor 134, a second photoelectric sensor 135 and a third photoelectric sensor 136.

The first photoelectric sensor 134 is electrically connected to the controller 60 to detect whether there is an inner box 199 on the side of the conveyor belt 100 close to the first guide plate 130.

[0052] like Figure 5 and 6As shown, the box pushing mechanism 2 includes an X-axis moving assembly 20 and a Z-axis moving assembly 22. The X-axis moving assembly 20 is suspended on the frame 6 along the X-axis, and the X-axis moving assembly 20 is connected to the Z-axis moving assembly 22. The X-axis moving assembly 20 includes a second cylinder 200, a cylinder fixing block 201, a second floating joint 202, a floating joint seat 203, a pair of stop studs 204, a pair of buffer blocks 205, a cylinder limit plate 206, a third fixing plate 212, a fourth fixing plate 213, a pair of first connecting plates 214 and a second connecting plate 215. The second cylinder 200 abuts against the third fixing plate 212 along the X-axis, and the cylinder fixing block 201 abuts against the third fixing plate 212. The cylinder fixing block 201 is provided with a through hole, and the head of the second cylinder 200 passes through the through hole and is fixedly connected to the cylinder fixing block 201 by screws. The second floating joint 202 is inserted into the through hole of the floating joint seat 203 and connected to the head of the second cylinder 200 by screws. The floating joint seat 203 is fixedly connected to the second connecting plate 215 by screws. A pair of buffer blocks 205 are respectively sleeved on a pair of stop studs 204. Threaded holes are provided on both sides of the cylinder fixing block 201.

The two ends of the fourth fixing plate 213 are respectively fixedly connected to the pair of first connecting plates 214 by screws. The connection of the third fixing plate 212, the fourth fixing plate 213 and the pair of first connecting plates 214 forms a rectangular structure. The fourth fixing plate 213 is fixedly connected to the frame 6 by screws. By providing a pair of stop studs 204 and a pair of buffer blocks 205, the buffering effect of the second cylinder 200 can be adjusted so that the second cylinder 200 can be decelerated and stopped smoothly when starting and ending the movement, thereby ensuring the smooth movement of the second connecting plate 215 along the X-axis.

[0053] The second cylinder 200 is electrically connected to the controller 60, and the controller 60 controls the movement of the second cylinder 200. The second cylinder 200 pushes the second floating joint 202 to drive the second connecting plate 215 to move along the X-axis. The second connecting plate 215 pushes the inner box placed on the table panel 133 to the outer box opening mechanism 3.

[0054] The X-axis moving assembly 20 also includes a pair of first linear rails 207, a pair of first sliders 208, a linear rail connecting block 209, a pair of linear rail fixing blocks 210 and a first reinforcing plate 211. A pair of first sliders 208 are respectively fixedly connected to the third fixing plate 212 by screws, and are parallel to the X-axis. A pair of first linear rails 207 are respectively slidably mounted on a pair of first sliders 208, and one end is abutted against the second connecting plate 215. A pair of linear rail fixing blocks 210 are trapezoidal and are respectively fixedly connected to a pair of first linear rails 207 by screws. The first reinforcing plate 211 is mounted on a pair of linear rail fixing blocks 210 and is fixedly connected to a pair of linear rail fixing blocks 210 by screws.

The first slide cylinder 222 drives the first limit plate 220 and the second push plate 221 to move, and is fixedly connected to the X-axis moving assembly 20. Specifically, the first limit plate 220 is L-shaped, and is fixedly connected to the second push plate 221 by screws. The width of the first limit plate 220 and the second push plate 221 is close to the length of the two inner boxes 199. The second push plate 221 is fixedly connected to the first slide cylinder 222 by screws, and the first slide cylinder 222 is fixedly connected to the second connecting plate 215 by screws. The right angle formed between the first limiting plate 220 and the second pushing plate 221 coincides with the right angle of the inner box 199, ensuring that when the X-axis moving assembly 20 drives the Z-axis moving assembly 22 to push the multiple inner boxes 199 along the X-axis, the multiple inner boxes 199 can be transported smoothly and neatly.

[0056] The first slide cylinder 222 is electrically connected to the controller 60, and the controller 60 controls the movement of the first slide cylinder 222. The first slide cylinder 222 drives the first limit plate 220 and the second push plate 221 to move up and down along the Z axis, so that the first limit plate 220 and the second push plate 221 are both in contact with the inner box 199.

[0057] The box pushing mechanism 2 is further provided with a fourth photoelectric sensor 216 . Specifically, the fourth photoelectric sensor 216 is fixed to the third sheet metal 217 by screws. The third sheet metal 217 is provided below the third fixing plate 212 .

[0058] The fourth photoelectric sensor 216 is electrically connected to the controller 60 and is used to detect whether there is an inner box 199 on the conveyor belt 100 directly below.

[0059] like Figures 7 to 13 As shown, the outer box cover opening mechanism 3 comprises a support assembly 30, a main moving assembly 31 and a secondary moving assembly 32 for supporting the inner box 199. One end of the support assembly 30 is connected with the main moving assembly 31, and the other end is connected with the secondary moving assembly 32. The main moving assembly 31 and the secondary moving assembly 32 are both arranged on the frame 6 along the Y axis. Wherein, the support assembly 30 comprises a pair of supporting plates 301 abutting against each other. One end of a pair of supporting plates 301 is both fixedly connected with the main moving assembly 31, and the other end is both fixedly connected with the secondary moving assembly 32, and the main moving assembly 31 and the secondary moving assembly 32 drive a pair of supporting plates 301 to separate. Specifically, the main moving assembly 31 comprises a pair of slide plates 310, a pair of slides 311, four slide fixing blocks 312, a first moving linear rail 313 and a second motor 314. A pair of slide plates 310 are respectively perpendicular to one end of a pair of support plates 301, and are respectively fixedly connected to the pair of support plates 301 by screws, and their upper and lower ends are fixedly connected to the slide fixing block 312 by screws. A pair of slides 311 are arranged in the first moving linear rail 313 and abut against the first moving linear rail 313, and their upper and lower ends are fixedly connected to the slide fixing block 312 by screws. The first moving linear rail 313 is arranged on the frame 6. The second motor 314 is connected to one end of the first moving linear rail 313.

[0060] The controller 60 is electrically connected to the second motor 314 and controls the second motor 314 to rotate. The second motor 314 drives the pair of slides 311 to move, thereby driving the four slide fixing blocks 312 and the pair of slide plates 310 to move, so that the pair of support plates 301 are separated to both sides.

[0061] The secondary moving assembly 32 includes four second sliders 320, a second linear rail 321, a pair of first linear rail plates 322 and a pair of second linear rail plates 323. The second slider 320 is slidably mounted on the second linear rail 321, and the second linear rail 321 is mounted on the frame 6. One of the first linear rail plates 322 is fixed to the two second sliders 320 by screws, and the other first linear rail plate 322 is fixed to the other two second sliders 320 by screws. A pair of first linear rail plates 322 are respectively fixedly connected to a pair of second linear rail plates 323 by screws, and a pair of second linear rail plates 323 are respectively fixedly connected to the other end of a pair of support plates 301 by screws. By setting the secondary moving assembly 32, not only a pair of support plates 301 can be supported, but also a pair of support plates 301 can be assisted to be separated smoothly.

[0062] The support assembly 30 further includes a pair of third guide plates 303 and a pair of fourth guide plates 304, wherein the pair of third guide plates 303 are respectively mounted on the pair of support plates 301 by screws along the X axis, and both abut against the inner box 199. The pair of fourth guide plates 304 are respectively mounted on the pair of support plates 301 by screws along the Y axis, and both abut against the inner box 199. Specifically, the cross section of the third guide plate 303 is U-shaped, and the cross section of the fourth guide plate 304 is L-shaped. The distance between the two third guide plates 303 is equal to the length of the two inner boxes 199. One of the third guide plates 303 is aligned with the first guide plate 130, and the other third guide plate 303 is aligned with the second guide plate 132. The width of the two fourth guide plates 304 is greater than or equal to the width of the inner box 199. By setting a pair of third guide plates 303 and a pair of fourth guide plates 304, the area for placing the inner box 199 is smoothly and regularly defined, so that the inner box 199 pushed from the box pushing mechanism 2 is neatly placed on a pair of support plates 301, which facilitates the adsorption and clamping box mechanism 4 to smoothly adsorb the inner box 199 and load it into the outer box 200.

[0063] The support assembly 30 further includes a pair of reinforcing blocks 305, the bottom surfaces of the pair of reinforcing blocks 305 are respectively fixedly connected to the pair of supporting plates 301 by screws, and the side surfaces are respectively fixedly connected to the pair of sliding seat plates 310 by screws.

[0078] A roller conveyor 8 is also provided on the frame 6. The outer box 200 is placed on the roller conveyor 8. The lifting bracket 504 is inserted between the roller gaps of the roller conveyor 8, thereby driving the outer box 200 to move up and down.

[0079] The positioning assembly 51 includes a second pad plate 510, a fifth cylinder 511, a sixth guide plate 512 and a seventh photoelectric sensor 513. The second pad plate 510 is in a "U" shape, with its side abutting against the sixth fixed plate 503, and the bottom fixedly connected to the lifting bracket 504 by screws. The fifth cylinder 511 is fixedly mounted on the second pad plate 510, and its guide rod (not shown) passes through the through hole of the sixth fixed plate 503. The sixth guide plate 512 is parallel to the fifth guide plate 507 and is fixedly connected to the fifth cylinder 511 by screws.

The fifth guide plate 507 is aligned with a pair of fourth guide plates 304 in the outer box opening mechanism 3, so that the adsorption clamping mechanism 4 can accurately load the regular inner box 199 into the outer box 200, simplifying the inner box 199 packing process.

[0081] The seventh photoelectric sensor 513 is electrically connected to the controller 60 and is used to detect whether the outer box 200 exists.

[0082] The inner box packing device also includes an empty box pushing mechanism 7, which is arranged at the rear end of the roller conveyor 8. The empty box pushing mechanism 7 includes a three-axis cylinder 70, a box pushing plate 71 and a seventh guide plate 72. The three-axis cylinder 70 is fixedly mounted on the fourth sheet metal 73 by screws, and the fourth sheet metal 73 is fixedly mounted on one side of the roller conveyor 8. The box pushing plate 71 is fixedly connected to the three-axis cylinder 70 by screws. The seventh guide plate 72 is fixedly mounted on the other side of the roller conveyor 8 by screws and is parallel to the box pushing plate 71.

[0083] The three-axis cylinder 70 is electrically connected to the controller 60, and the controller 60 controls the movement of the three-axis cylinder 70. The three-axis cylinder 70 drives the box pusher plate 71 to push the outer box 200, and pushes the outer box 200 transported on the roller conveyor 8 to the bottom of the multiple inner boxes 199 on the support assembly 30, so as to facilitate the accurate loading of the multiple inner boxes 199 into the outer box 200.

[0084] The inner box packing device further includes a pair of outer box positioning components 9. The pair of outer box positioning components 9 are fixed below the roller conveyor 8. The distance between the two outer box positioning components 9 is greater than the length of an outer box 200. The pair of outer box positioning components 9 limit the outer box 200 transported on the roller conveyor 8, so that the outer box 200 is located directly below the multiple inner boxes 199 on the support component 30, which facilitates the multiple inner boxes 199 to be stably loaded into the outer box 200.

[0085] During operation, the roller conveyor 8 transports the outer box 200, and the three-axis cylinder 71 pushes the outer box 200 to be transported forward along the seventh guide plate 72. When the seventh photoelectric sensor 513 detects that there is material on the lifting bracket 504, the optical signal is transmitted to the controller 60. The controller 60 controls the roller conveyor 8 to stop moving, and then controls the sixth cylinder 91 to rise and drive the second limit plate 93 to limit the outer box 200. Then the controller 60 controls the fourth cylinder to lift the outer box 200 upward to a certain height along the Z axis, and then controls the fifth cylinder 511 to push the outer box 200 to the left along the X axis until the outer box 200 abuts against the fifth guide plate 507. The controller 60 controls the fifth cylinder 511 to return to its position, and then the controller 60 controls a pair of telescopic cylinders 330 to drive a pair of telescopic plates 331 to open the left and right rocking covers of the outer box 200, and the outer box 200 is ready.

[0086] At the same time, the first inner box 199 from the previous process is placed on the conveyor belt 100, and the first motor 101 drives the conveyor belt 100 to move forward along the Y axis. The first inner box 199 stops under the obstruction of the first guide plate 130, and the first photoelectric sensor 134 detects that there is material on the conveyor belt 100, and transmits the optical signal to the controller 60. The controller 60 receives the signal but does not issue a command. Then, the second inner box 199 is transported to the back of the first inner box 199 and arranged neatly. The fourth photoelectric sensor 216 detects that there is material on the conveyor belt 100, and transmits the optical signal to the controller 60. After the controller 60 receives the optical signals of the first photoelectric sensor 134 and the fourth photoelectric sensor 216, it controls the first cylinder 111 to move, and the first push plate 110 connected to the first cylinder 111 pushes the two neatly arranged inner boxes 199 along the first guide plate 130 and the second guide plate 132 to the table plate 133 corresponding to the second photoelectric sensor 135. The second photoelectric sensor 135 detects that there is material on the table plate 133, and the controller 60 receives the signal but does not issue a command. The controller 60 receives the optical signals from the first photoelectric sensor 134 and the fourth photoelectric sensor 216 again, and controls the first cylinder 111 to move, and pushes the third inner box 199 and the fourth inner box 199 to the table plate 133 corresponding to the second photoelectric sensor 135. At the same time, the third inner box 199 and the fourth inner box 199 push the first inner box 199 and the second inner box 199 to move to the table plate 133 corresponding to the third photoelectric sensor 136. At this time, the second photoelectric sensor 135 and the third photoelectric sensor 136 both detect that there is material on the table plate 133, and both transmit optical signals to the controller 60. The controller 60 controls the first slide cylinder 222 to drive the first limit plate 220 and the second push plate 221 to move downward along the Z axis, and the bottom surface of the first limit plate 220 abuts against the upper surface of the inner box 199, and the left side of the second push plate 221 abuts against the right side of the inner box 199. Then the controller 60 controls the second cylinder 200 to drive the first limit plate 220 and the second push plate 221 to push the four well-arranged inner boxes 199 to the left along the X-axis. The four well-arranged inner boxes 199 move along the pair of third guide plates 303 to the pair of pallets 301 and abut against the pair of fourth guide plates 304. The fifth photoelectric sensor 307 detects that there is material on the pallet 301. The controller 60 receives the optical signal of the fifth photoelectric sensor 307. The controller 60 controls the third motor 430 to drive the second moving linear rail 431 and the adsorption clamping assembly 40 to move downward along the Z-axis for a certain distance. When the bottom plate 405 contacts the inner box 199, the sixth photoelectric sensor detects that there is material on the pallet 301 and transmits the optical signal to the controller 60. The controller 60 controls the third cylinder 402 to return to its position. The reed switch of the third cylinder 402 is activated and transmits the position signal of the third cylinder 402 to the controller 60. The controller 60 controls the clamping cylinder 410 to drive the first clamping plate 411 to clamp the side of the inner box 199.After the clamping cylinder 410 clamps the inner box 199, the reed switch of the clamping cylinder 410 is activated and transmits the position signal of the clamping cylinder 410 to the controller 60. The controller 60 controls the vacuum generator to realize that the multiple vacuum suction cups 401 smoothly adsorb the four inner boxes 199. After the adsorption work is completed, the controller 60 controls the first lifting assembly 43 to move upward a certain distance to make the four inner boxes 199 separate from the pair of pallets 301. Then the controller 60 controls the second motor 314 to drive the main moving assembly 31 to drive the pair of pallets 301 to separate a certain distance to the front and rear sides. The pair of pallets 301 separates and drives the pair of expansion plates 306 to open the front and rear covers of the outer box 200. The controller 60 controls the third motor 430 to make the adsorption clamping mechanism 4 drop to the first height, and the controller 60 controls the clamping cylinder 410 to return to the position to release the four inner boxes 199. Then the controller 60 controls the vacuum generator to make the multiple vacuum suction cups 401 release the four inner boxes 199, and controls the third cylinder 402 to push the four inner boxes 199 downward to be loaded into the outer box 200. The next group of inner boxes 199 is loaded by the controller 60 controlling the third motor 430 to lower the suction clamping mechanism 4 to a second height. One outer box 200 can hold eight inner boxes 199. After the outer box 200 is full, the controller 60 controls the fourth cylinder 505 to descend and return to its original position, and controls the roller conveyor 8 to start and then transport the outer box 200 to the next process.

[0087] The utility model places the conveying surface 103 of the conveyor belt 100, the table surface 137 of the table panel 133 and the plate surface 308 of a pair of pallets 301 in the same plane, so that the inner box 199 does not bump or flip during transportation, so that the inner box 199 can be stably loaded into the outer box 200, thereby ensuring the product quality in the inner box 199. By setting the first guide plate 130, the inner box 199 transmitted by the conveyor belt 100 can be limited, and the inner box 199 can be preliminarily regulated, thereby ensuring the regular operation of the pushing work. By setting the first guide plate 130 and the second guide plate 132 parallel to each other on the table panel 133, and the distance between the first guide plate 130 and the second guide plate 132 is a multiple of the length of the inner box 199, all the inner boxes 199 pushed by the pushing component 11 can run smoothly and regularly between the first guide plate 130 and the second guide plate 132, thereby ensuring the regular operation of the subsequent adsorption work. By setting the third guide plate 303 and the fourth guide plate 304 on the pallet 301, the area where the inner box 199 is placed is smoothly and regularly defined, which facilitates the adsorption component 40 to smoothly adsorb the well-ordered inner box 199. By setting the third cylinder 402 to be fixedly connected with the bottom plate 403, the third cylinder 402 drives the bottom plate 403 to press down the inner box 199, and the inner box 199 is more regular, so that the vacuum suction cup 400 adsorbs the inner box 199 more evenly and tightly. Through the joint action of the adsorption component 40 and the clamping component 41, it can ensure that the transportation process of the inner box 199 is more stable. The main moving component 31 and the auxiliary moving component 32 drive a pair of pallets 301 to separate, and the adsorbed inner box 199 can be directly placed in the outer box 200 downward along the Z axis without the need for moving and transporting along the X axis or the Y axis, which simplifies the box entry process and improves work efficiency. By providing a pair of expansion plates 306 and a pair of telescopic plates 331, the cover of the outer box 200 can be automatically opened and kept open, so that the inner box 199 can be loaded into the outer box 200 more smoothly. The controller 60 controls the movement of the cylinder and the motor throughout the entire process of the utility model, which has a high degree of automation, reduces manpower input, and improves transportation efficiency.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
