Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figures 1-8As shown, this utility model provides an automatic pallet loading and unloading device, including a base 1 and a palletizing mechanism 2 and a robot arm 3 mounted on the base 1. The palletizing mechanism 2 includes a conveying part 21 and fixed frames 22 disposed on both sides of the conveying part 21. One end of the fixed frame 22 is provided with a palletizing frame 221 and symmetrical support mechanisms 23 are provided on both sides of the bottom of the palletizing frame 221. The bottom of the palletizing frame 221 communicates with the inside of the fixed frame 22. The support mechanisms 23 are used to support the pallet 10 inside the palletizing frame 221 and receive the pallet 10 from the conveying part 21. The other end of the fixed frame 22 is provided with a placement position 2. 22. The conveying unit 21 includes a driving component 11 and a receiving component 12. The receiving component 12 receives the pallet 10 held by the robot arm 3 in the placement position 222. The receiving component 12 is driven to move towards the palletizing rack 221 by a driving component. The receiving component 12 includes a slider 121, a connecting frame 122 and a receiving platform 123. The slider 121 is driven to be connected to the driving component 11. The bottom of the connecting frame 122 is connected to the top surface of the slider 121. The connecting frame 122 is provided with a first longitudinal driving component 124. The first longitudinal driving component 124 is used to drive the receiving platform 123 to move up and down.

[0030] Furthermore, such as Figures 5-7 As shown, both support mechanisms 23 include a lateral drive member 231 and a support assembly 24. The support mechanism 23 supports the pallet 10 within the palletizing rack 221 via the support assembly 24. The lateral drive member 231 drives the support assembly 24, causing it to move closer to or further away from the receiving platform 123. The support assembly 24 includes a second longitudinal drive member 241 and a support plate 242. The support plate 242 supports the pallet 10 within the palletizing rack 221. The output shaft of the lateral drive member 231 is fixedly installed with the second longitudinal drive member 241, and the output shaft of the second longitudinal drive member 241 is fixedly installed with the support plate 242, and is used for the lifting and lowering movement of the support plate 242. The support plate 242 has a shovel portion 243 on the side near the receiving platform 123, used to separate the bottom pallet 10 within the palletizing rack 221 from the pallet stack above.

[0031] Specifically, such as Figures 1-8As shown, the robot arm 3 grips the pallet 10 and transports it to the placement position 222 at the other end of the fixed frame 22. Simultaneously, the drive unit moves the receiving platform 123 into the placement position 222. The robot arm 3 places the pallet 10 onto the receiving platform 123 in the placement position 222. The drive unit then moves the receiving platform 123, loaded with the pallet 10, downwards towards the pallet rack 221. The first longitudinal drive unit 124 pushes the receiving platform 123 into the pallet rack 221. During this process, the second longitudinal drive unit 241 first drives the support plate 242 downwards, causing the pallet stack placed on top of the support plate 242 to move downwards and be placed on the receiving platform. At position 123, the first longitudinal drive member 124 keeps the height of the receiving platform 123 unchanged, and then drives the second longitudinal drive member 241 to move away from the pallet stack through the transverse drive member 231, and supports the pallet stack through the receiving platform 123. Then, the second longitudinal drive member 241 drives the support plate 242 to descend, so that the height of the top surface of the support plate 242 is lower than the bottom surface of the pallet 10 located on the receiving platform 123. The transverse drive member 231 drives the support plate 242 to move below the bottom surface of the pallet 10 on the receiving platform 123. The second longitudinal drive member 241 drives the support plate 242 to lift the pallet stack upward, realizing the automated palletizing effect.

[0032] Furthermore, such as Figures 1-8 As shown, the top surface of the receiving platform 123 is provided with several support blocks 120 for supporting the pallet 10. A limiting block 125 is provided at the edge of the top surface of the receiving platform 123 for fixing the pallet 10.

[0033] Specifically, such as Figures 1-8 As shown, the robot arm 3 clamps the pallet 10 and transports it to the placement position 222 at the other end of the fixed frame 22. Simultaneously, the drive unit moves the receiving platform 123 into the placement position 222. The robot arm 3 places the pallet 10 onto the receiving platform 123 in the placement position 222, and the first longitudinal drive unit 124 pushes the receiving platform 123 into the pallet stacking rack 221, thereby pushing the pallet 10 on the receiving platform 123 into the pallet stacking rack 221, integrating the pallet 10 on the receiving platform 123 into the pallet stack. However, at this time, it is necessary to receive... Platform 123 temporarily supports the pallet stack, waiting for support mechanism 23 to lift the pallet stack. Since the pallet stack has a certain weight, the support block 120 can separate the bottom surface of the pallet 10 from the top surface of the receiving platform 123, avoiding negative pressure between the pallet stack and the receiving platform 123, which would cause suction when the pallet 10 is separated from the receiving platform 123. At the same time, by setting a limiting block 125 on the edge of the top surface of the receiving platform 123, the pallet 10 can be misaligned during the transportation process driven by the drive component 11 on the receiving platform 123.

[0034] Based on the above, the drive component 11 can be a lead screw drive structure, thereby improving the ability of the pallet 10 to move accurately to the bottom of the palletizing frame 221 and achieving a precise palletizing effect.

[0035] In addition, the receiving platform 123 is used to support the bottom center of the pallet 10, while the support plate 242 supports the bottom sides of the pallet 10. The receiving platform 123 and the support plate 242 do not interfere with each other.

[0036] Furthermore, such as Figures 1-8 As shown, the fixing frame 22 has a support part 223 on one side near the fixing frame 22, which is used to support the bottom of both sides of the pallet 10. When the support part 223 is supported on the bottom of the pallet 10, the two fixing frames 22 are limited and slidably engaged with the sides of the pallet 10. The bottom of the stacking frame 221 is provided with a passage part 224 between the support part 223 and the bottom of the stacking frame 221 for the pallet 10 to pass through.

[0037] Specifically, such as Figures 1-8 As shown, the robot arm 3 clamps the pallet 10 and transports it to the placement position 222 at the other end of the fixed frame 22. At the same time, the drive unit drives the receiving platform 123 to move into the placement position 222. The robot arm 3 places the pallet 10 into the receiving platform 123 in the placement position 222, and the first longitudinal drive unit 124 pushes the receiving platform 123 to move into the palletizing frame 221. During the movement, the bottom of the pallet 10 slides against the support part 223.

[0038] Furthermore, such as Figures 1-8 As shown, the working end of the robotic arm 3 is provided with a lifting drive 31 and a clamping part 32. The lifting drive 31 is used to drive the clamping part 32 to move up and down, and the clamping part 32 is used to clamp the tray 10. The output end of the lifting drive 31 is provided with a mounting bracket 33 for mounting the clamping part 32. The clamping part 32 includes a first clamping area 321 and a second clamping area 322. The second clamping area 322 surrounds the first clamping area 321. The first clamping area 321 is used to fix the hardware on the tray 10, and the second clamping area 322 is used to fix the tray 10.

[0039] Specifically, such as Figures 1-8As shown, based on the above-described palletizing procedure, the pallet 10 loaded with hardware can also be transferred. The pallet 10 with hardware is stacked inside the palletizing rack 221. The first longitudinal drive member 124 pushes the receiving platform 123 into the palletizing rack 221, causing the receiving platform 123 to support the bottom of the pallet stack. The second longitudinal drive member 241 drives the support plate 242 to descend, causing the support plate 242 to detach from the pallet stack. The second longitudinal drive member 241 drives the support plate 242 to rise, making the bottom surface of the support plate 242 flush with the top surface of the bottom pallet 10 of the pallet stack. The transverse drive member 231 drives the shovel part 243 of the support plate 242 to insert into the pallet stack, separating the bottom pallet 10 from the pallet stack and supporting it on the bottom surface of the pallet stack. The second longitudinal drive member 231 then drives the shovel part 243 of the support plate 242 into the pallet stack, causing the bottom pallet 10 of the pallet stack to separate from the pallet stack and support it on the bottom surface of the pallet stack. The drive support plate 242 driven by component 241 moves the pallet stack down and resets. At the same time, the receiving platform 123 is moved downward by the first longitudinal drive component 124. The receiving platform 123 is driven by the drive assembly 11 to move the pallet 10 to the placement position 222. During this process, the pallet 10 passes through the passage 224 at the bottom of the pallet rack 221 and slides with the support component 223. After reaching the placement position 222, the robot arm 3 clamps the pallet 10. The first clamping area 321 clamps the hardware, and the second clamping area 322 clamps the pallet 10, so that the pallet 10 and the hardware on the pallet 10 move simultaneously. It is worth noting that the first clamping area 321 and the second clamping area 322 can be distributed with several suction cups to achieve a better clamping effect.

[0040] Based on the above, the first longitudinal drive member 124, the second longitudinal drive member 241, and the transverse drive member 231 can be cylinders or lead screw drive structures.

[0041] The following is a detailed explanation of the working principle of this utility model;

[0042] The robotic arm 3 grips the pallet 10 and transports it to the placement position 222 at the other end of the fixed frame 22. At the same time, the drive unit drives the receiving platform 123 to move into the placement position 222. The robotic arm 3 places the pallet 10 into the receiving platform 123 in the placement position 222. The drive unit drives the receiving platform 123 loaded with the pallet 10 to move under the palletizing frame 221. The first longitudinal drive unit 124 pushes the receiving platform 123 into the palletizing frame 221, thereby pushing the pallet 10 on the receiving platform 123 into the palletizing frame 221 and integrating it into the pallet stack in the palletizing frame 221. The supporting mechanism 23 provides support, achieving an automated pallet 10 palletizing effect.
