[0028] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] like Figures 1 to 4 As shown, in one embodiment of the present invention, the material box delivery system 100 includes a transfer platform 1, a loading device 2, a loading rack 3, a recovery rack 4 and a recovery device 5, and a loading tray 11 is provided on the transfer platform 1; the loading device 2 includes a loading platform 21 and a pushing mechanism 22 provided on the loading platform 21, the loading platform 21 is slidably provided on the ground, and the loading platform 21 can slide between a first position and a second position, and the pushing mechanism 22 is used to push the material box on the loading platform 21 to the loading tray 11 when the loading platform 21 is in the first position; the loading rack 3 includes a loading roller 31 and a conveying mechanism 32, when the loading platform 21 is in the second position, the loading roller 31 is docked with the loading platform 21, and the conveying mechanism 32 is mounted on the loading roller Above the road 31 and the loading platform 21, the conveying mechanism 32 is used to convey the material box on the loading roller 31 to the loading platform 21; the recovery rack 4 includes a recovery roller 41 arranged side by side with the loading roller 31; the recovery device 5 includes a connecting frame 51, a recovery platform 52 rotatably connected to the connecting frame 51, and a collecting mechanism 53 arranged on the connecting frame 51; the connecting frame 51 is slidably arranged on the ground, and the connecting frame 51 can slide between the first position and the third position. When the connecting frame 51 is in the first position, the collecting mechanism 53 is used to pull the empty material box on the carrier 11 to the recovery platform 52 when the connecting frame 51 is in the first position; when the connecting frame 51 is in the third position, the recovery platform 52 rotates to allow the empty material box to slide to the recovery roller 41.

[0030] In the above embodiment, the loading rack 3 is used to store boxes containing workpieces to be assembled, and the loading device 2 is used to move the boxes on the loading rack 3 to the carrier 11, and the transfer platform 1 moves the boxes to the assembly station; after the assembly is completed, the transfer platform 1 moves the empty boxes back to the first position, and the recovery device 5 recovers the empty boxes and transfers them to the recovery rack 4; the above process is repeated to complete the vehicle assembly. The entire process can be sensed in place by setting sensors, and the processor runs a preset program to fully automatically control the transfer platform 1, loading device 2, loading rack 3, recovery rack 4 and recovery device 5. The entire process does not require workers to perform handling operations between running equipment, which ensures the safety of workers and improves production efficiency and the accuracy of transportation and docking, thereby avoiding deformation and damage of the workpieces to be assembled caused by the boxes falling or the parts in the boxes falling during the handling and transportation process.

[0031] Specifically, the transfer platform 1 can be an AGV trolley. The bins containing the workpieces to be assembled are stacked on the loading roller 31, and the bins are able to move on the loading roller 31. When the loading platform 21 returns to the second position, the transport mechanism 32 transports a bin from the loading roller 31 to the loading platform 21. The loading platform 21 then transports the bin to the first position. The pushing mechanism 22 pushes the bin to the left until the bin completely falls onto the carrier 11. At this time, the pushing mechanism 22 retracts, and the loading platform 21 returns to the second position. That is, when the loading platform 21 returns to the second position, the transport mechanism 32 can pre-transfer a bin from the loading roller 31 to the loading platform 21, reducing intermediate waiting time and improving assembly efficiency.

[0032] When the transfer platform 1 moves the empty material box to the first position, the connecting frame 51 moves to the first position so that the recovery platform 52 docks with the carrier 11. The empty material box is pulled or sucked by the collecting mechanism 53 and moved to the recovery platform 52. The connecting frame 51 moves to the third position, and at the same time, the loading platform 21 moves from the second position to the first position to load the material. When the connecting frame 51 moves to the third position, the recovery platform 52 rotates counterclockwise so that the recovery platform 52 docks with the recovery roller 41. The empty material box slides down and moves onto the recovery platform 52 under the action of gravity, thereby realizing the complete empty and full box exchange function. In the present invention, the assembly efficiency is improved by reducing the intermediate waiting time.

[0033] Specifically, rollers are arranged in an array on the loading platform 21, the loading roller 31, the recovery platform 52 and the recovery roller 41. By setting the rollers, the friction between the material box and the loading platform 21, the loading roller 31, the recovery platform 52 and the recovery roller 41 is reduced, and at the same time, wear of the material box or the loading platform 21, the loading roller 31, the recovery platform 52 and the recovery roller 41 can be avoided.

[0034] In one embodiment, the loading roller conveyor 31 includes a first inclined section 311 and a transfer section 312. The transfer section 312 can be raised and lowered vertically. The first inclined section 311 is tilted downward toward the transfer section 312. The transport mechanism 32 is mounted above the transfer section 312 and extends away from the first inclined section 311. When the loading platform 21 is in the second position, the transfer section 312 descends so that its ends dock with the first inclined section 311 and the loading platform 21, respectively. The transfer section 312 then ascends to push the container into the transport mechanism 32, which is used to transport the container to the loading platform 21. The first inclined section 311 has a high end and a low end. The low end of the first inclined section 311 docks with the transfer section 312. The container slides on the first inclined section 311 under its own weight until it reaches the transfer section 312. The transfer section 312 is sized to accommodate a container. When the material box on the transfer section 312 is removed, the next material box can be automatically filled into the transfer section 312. In a preferred embodiment, a stop mechanism can be further provided between the first inclined section 311 and the transfer section 312. The stop mechanism is used to separate the material box on the first inclined section 311 from the material box on the transfer section 312, and can prevent the material box on the first inclined section 311 from exerting pressure on the material box on the transfer section 312. The stop mechanism can specifically include a baffle of a cylinder, which is connected to the piston rod of the cylinder. The cylinder extends so that the baffle stops between the material box on the transfer section 312 and the material box on the first inclined section 311.

[0035] Based on the above embodiment, the loading platform 21 is provided with an array of balls 211, and an avoidance channel 212 is also formed on the loading platform 21. The pushing mechanism 22 includes a pushing drive 221 and a push rod 222. The pushing drive 221 is installed on the lower side of the loading platform 21. One end of the push rod 222 is connected to the output end of the pushing drive 221, and the other end extends from the avoidance channel 212. The pushing drive 221 drives the push rod 222 to slide in the avoidance channel 212 to push the material box to the carrier 11. The loading platform 21 can have a base plate, and a position for installing the balls 211 and the avoidance channel 212 is formed by grooves on the base plate. The loading platform 21 can also be a frame structure, and a plurality of slide grooves with balls 211 installed are provided on the frame, and an avoidance channel 212 is formed between two adjacent slide grooves. The pushing drive 221 is a cylinder, and a horizontal plate can be set at one end of the push rod 222 away from the pushing drive 221. By setting the horizontal plate, the thrust acting on the material box is ensured to be uniform, avoiding the material box from tipping or tilting during movement, and ensuring safety and reliability during the material box transportation process.

[0036] The transport mechanism 32 includes a mounting frame 321, a first trolley 322, a clamping assembly 323, and a plurality of columns 324. The mounting frame 321 is mounted above the transfer section 312 via the plurality of columns 324. The trolley is slidably connected to the mounting frame 321. The clamping assembly 323 includes clamping arms 325 located on either side of the trolley. The clamping arms 325 move toward or away from each other to clamp or release the material box. The mounting frame 321 is a square frame that covers at least the area where the loading platform 21 and the transfer section 312 are located, ensuring that the trolley's travel range can meet the material box transport requirements. Each clamping arm 325 includes a first lifting drive 3251, a first clamping drive 3252, and a first clamping block 3253. The first lifting drive 3251 is connected to the first trolley 322, the first clamping drive 3252 is connected to the output end of the first lifting drive 3251, and the first clamping block 3253 is connected to the output end of the first clamping drive 3252. The first clamping drive 3252 can synchronously drive the two first clamping blocks 3253, or two first clamping drives 3252 can be provided to separately drive the two first clamping blocks 3253. When transporting a material box, the crane moves to above the transfer section 312, and the first lifting drive 3251 drives the first clamping drive 3252 and the first clamping block 3253 to descend to a designated position. The first clamping drive 3252 drives the two first clamping blocks 3253 to approach each other and clamp the material box. The first lifting drive 3251 then drives the two first clamping blocks 3253 to move the material box toward the upper feeding platform 21 until the material box is above the loading platform 21. At this time, the first lifting drive 3251 drives the two first clamping blocks 3253 to move the material box downward, and the material box contacts the loading platform 21. The first clamping drive 3252 drives the two first clamping blocks 3253 to move away from each other to release the material box, thereby achieving the transport of the material box.

[0037] In one embodiment, the recovery roller 41 includes a receiving section 411 and a second inclined section 412. The second inclined section 412 is tilted downward in a direction away from the receiving section 411. The receiving section 411 can be raised and lowered in the vertical direction. The receiving section 411 rises to dock with the second inclined section 412, and then descends to dock with the recovery platform 52 in the third position. The second inclined section 412 is tilted downward from left to right. The receiving section 411 can move in the up-down direction. When the recovery platform 52 is in the third position, the receiving section 411 descends to dock with the recovery platform 52, and the height of the receiving section 411 is lower than the height of the recovery platform 52. The recovery platform 52 tilts toward the side where the receiving section 411 is located, causing the empty material box on the recovery platform to slide onto the receiving section 411. The receiving section 411 rises to dock with the second inclined section 412. Under the action of gravity, the empty material box can slide down along the inclined direction of the second inclined section 412 to achieve recycling and sorting of the material box.

[0038] In addition, the recycling rack 4 also includes a stacking assembly 42 mounted above the receiving section 411. The stacking assembly 42 includes a mounting frame 421 and two clamping arms 422 disposed on either side of the mounting frame 421. The mounting frame 421 is mounted above the receiving section 411. Each clamping arm 422 includes a second clamping driver 4221 and a second clamping block 4222. The second clamping driver 4221 is connected to the mounting frame 421. The second clamping block 4222 is connected to the output end of the second clamping driver 4221. The two second clamping drivers 4221 are used to respectively drive the two second clamping blocks 4222 to move toward or away from each other to clamp or release the empty bins. By providing the stacking assembly 42, the empty bins can be stacked, improving space utilization and enabling the recycling roller 41 to store more empty bins.

[0039] Based on the above embodiment, when the recovery platform 52 rotates to make the empty material box slide to the receiving section 411, the receiving section 411 rises, so that the empty material box is clamped by the two clamping arms 422, and then the receiving section 411 descends, so that there is a gap between the empty material box clamped by the clamping arms 325 and the receiving section 411, and the recovery platform 52 transports the next empty material box to the third position, and the next empty material box is moved to the gap, the receiving section 411 rises and the two clamping arms 325 release the empty material box, so that the two empty material boxes are stacked and moved to the second inclined section 412 and slide down along the second inclined section 412, thereby realizing full utilization of the space where the recovery roller 41 is located and storing more empty material boxes.

[0040] Similarly, the material boxes on the loading roller 31 can also be stacked. The stacking of two material boxes is used for illustration. The loading boxes on the first inclined section 311 are stacked in two layers, and the upper material box and the lower material box are arranged in a one-to-one correspondence. The two stacked material boxes slide synchronously onto the loading platform 21. When transporting the upper material box, the first lifting drive 3251 maintains the initial state, and the second clamping drive 4221 drives the two first clamping blocks 3253 to clamp the upper material box. The first crane 322 drives the first clamping blocks 3253 for transportation, and the lower material box is transported after the first lifting drive 3251 drives the first clamping drive 3252 to descend.

[0041] Specifically, the collecting mechanism 53 includes a second trolley 531, a material picking assembly 532, and two support frames 533 arranged opposite to each other. The two support frames 533 are respectively arranged on both sides of the recycling platform 52. The second trolley 531 is slidably arranged on the top of the two support frames 533. One end of the material picking assembly 532 is connected to the second trolley 531, and the other end of the material picking assembly 532 is provided with a material picking portion. The two support frames 533 are arranged opposite to each other and are connected to the two side edges of the recycling platform in a one-to-one correspondence. The second trolley 531 is slidably arranged on the top of the two support frames 533 and thus mounted on the second trolley 531. The second trolley 531 drives the material picking assembly 532 to move rightward, so that the material picking assembly 532 can extend to contact and cooperate with the empty material box on the carrier 11. During the retraction of the material picking assembly 532, the empty material box is moved to the recycling platform 52. During the retraction of the material picking assembly 532, the second trolley 531 moves leftward synchronously, thereby accelerating the transportation speed while ensuring the stable transportation of the empty material box.

[0042] In order to ensure that the material box does not slide down due to inertia during the movement of the transfer platform 1, a rib is formed at the edge of the carrier 11, and the rib is surrounded by a structure that matches the shape of the material box, thereby limiting and stopping the empty material box.

[0043] Based on the above embodiment, the material retrieving assembly 532 includes a second lifting drive 5321 and a recovery rod 5322. The second lifting drive 5321 is connected to the crane. One end of the recovery rod 5322 is connected to the output end of the second lifting drive 5321, and the other end forms a material retrieving unit. By providing the second lifting drive 5321, when the recovery rod 5322 contacts and engages with the empty material bin, the second lifting drive 5321 drives the recovery rod 5322 and the empty material bin upward to cross the retaining edge. Furthermore, the material retrieving unit recovery method occupies less space than the clamping recovery method, and the difficulty of transporting the empty material bin is less than that of transporting a bin containing workpieces to be assembled. Using the material retrieving unit handling method also ensures the stability of the empty material bin during transportation.

[0044] The retrieving portion can be a suction head structure. By adopting a suction head-shaped retrieving portion, negative pressure is generated at the suction head, ensuring that the recovery rod 5322 is stably connected to the empty material box during transportation, preventing the empty material box from detaching or falling. The retrieving portion can also be a snap-fit ​​structure that matches the folded edge of the empty material box. When the retrieving rod 5322 approaches the empty material box under the action of the driving, the second lifting assembly drives the retrieving rod 5322 to rise when it contacts the empty material box, thereby driving the retrieving portion to snap into the folded edge of the empty material box, thereby preventing the empty material box from detaching or falling.

[0045] When the displacement requirements for the first lifting drive 3251, the first clamping drive 3252, the second lifting drive 5321, and the second clamping drive 4221 are only two stages, these drives can all be cylinders. If stepless position adjustment is required, the first lifting drive 3251, the first clamping drive 3252, the second lifting drive 5321, and the second clamping drive 4221 can use a module or screw drive structure.

[0046] The loading rack 3 also includes a sensor and an alarm. The sensor is located at the junction of the first inclined section 311 and the transfer section 312. The sensor is used to detect whether there is a material box on the first inclined section 311. If the sensor detects that there is no material box on the first inclined section 311, the alarm is controlled to sound an alarm to remind the staff to store the material box containing the workpieces to be assembled on the first inclined section 311. Both the sensor and the alarm can adopt existing technologies. For example, the sensor can be a camera or a photoelectric switch, and the alarm can be a buzzer, an alarm light, a communication element, or a combination thereof. By providing a timed reminder of material shortage, the sensor and the alarm can reduce the waiting time caused by material shortage.

[0047] Similarly, the recycling rack 4 can also be equipped with sensors and alarms. The sensors are used to detect the storage status of the empty boxes, such as whether they are tilted or swayed or filled with the second inclined section 412. The alarm is used to sound an alarm when the status of the empty boxes on the second inclined section 412 is abnormal, reminding the staff to collect or sort the empty boxes in time.

[0048] In the present invention, the second position and the third position are fixed positions, and the first position only needs to be between the second position and the third position, preferably at the center of the second position and the third position, thereby ensuring that the moving distances of the loading platform 21 and the recovery platform 52 are consistent, shortening the waiting time for movement. In addition, since the transfer platform 1 adopts an AGV trolley, the inertial stop position accuracy is insufficient, and the position where the transfer platform 1 stops is taken as the first position. The loading platform 21 and the recovery platform 52 are both provided with a sensing component that matches the transfer platform 1. The loading platform 21 or the recovery platform 52 stops when it moves to the sensing component and sends a signal, thereby ensuring the docking of the transfer platform 1 and the loading platform 21, as well as the docking of the transfer platform 1 and the recovery platform 52. The loading platform 21 and the recovery platform 52 can be slidably set on the ground by two side-by-side slide rails, thereby ensuring the position accuracy of the loading platform 21 and the recovery platform 52 when they stop.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
