Embodiment

[0029] Referring to the attached Figures 1 to 5 , an AGV intelligent handling robot, comprising an AGV forklift body 1, a fork portion 4 is arranged on the output end of the AGV forklift body 1, an auxiliary support mechanism 2 is arranged on the AGV forklift body 1, the auxiliary support mechanism 2 is arranged above the fork portion 4, the fork portion 4 is used for supporting the bottom of a shelf 3, and the auxiliary support mechanism 2 is used for clamping and fixing the upright column of the shelf 3.

[0030] The auxiliary support mechanism 2 includes a support frame 201 fixed on the AGV forklift body 1, two bearing seats 202 are arranged on the support frame 201, a double-headed screw rod 203 is rotatably installed on the two bearing seats 202 through bearings, one end of the double-headed screw rod 203 is connected to a driving mechanism 204, two threaded sleeves 205 are installed on the double-headed screw rod 203 through threads, a sliding plate 206 is arranged on the threaded sleeve 205, and a clamping plate 207 is vertically installed on the sliding plate 206.

[0031] The driving mechanism 204 includes a mounting plate 2041 fixed on the support frame 201, a driving motor 2042 is fixedly installed on the mounting plate 2041, a driving synchronous pulley 2043 is fixedly installed on the motor shaft of the driving motor 2042, a driven synchronous pulley 2044 is fixedly installed on the double-headed screw rod 203, and the driving synchronous pulley 2043 and the driven synchronous pulley 2044 are connected by a synchronous belt 2045.

[0032] A limiting plate 208 is vertically installed on the clamping plate 207, and a plurality of reinforcing ribs 209 are arranged between the clamping plate 207 and the sliding plate 206. The reinforcing ribs 209 are arranged between the clamping plate 207 and the sliding plate 206, and their main purpose is to enhance the structural strength between these two plates. Through the reinforcing ribs 209, the stress generated by the clamping force or processing force can be shared and dispersed, avoiding the structure from bending or deforming when subjected to external forces, thereby improving the overall stability and durability.

[0033] A slider 210 is fixedly installed on the back of the sliding plate 206, and a guide rail 211 is fixedly installed on the support frame 201. The length direction of the guide rail 211 is parallel to the length direction of the double-headed screw 203, and the slider 210 is slidably installed on the guide rail 211. During the movement of the sliding plate 206, the slider 210 fixedly installed on its back will slide on the guide rail 211 fixedly installed on the support frame 201. Since the length direction of the guide rail 211 is parallel to the length direction of the double-headed screw 203, the slider 210 will perform a smooth linear motion along the direction of the guide rail 211, thereby ensuring that the sliding plate 206 and the clamping plate 207 thereon can accurately move along the length direction of the double-headed screw 203, realizing the clamping or loosening operation of the column of the shelf 3. Such a structural design can improve the motion accuracy and stability of the entire auxiliary support mechanism 2 and ensure the reliability of the clamping operation.

[0034] A protective pad 212 is provided on the side of the limit plate 208 and the clamping plate 207 close to the shelf 3. During the process of clamping the column of the shelf 3, the protective pad 212 can prevent the clamping plate 207 and the limit plate 208 from directly contacting the shelf 3, thereby reducing the wear and scratches on the surface of the shelf 3 and protecting the appearance and quality of the shelf 3. The protective pad 212 can increase the friction between the clamping plate 207 and the column of the shelf 3, making the clamping more stable and improving the safety during the handling process. The protective pad 212 is generally made of materials with certain elasticity and wear resistance, and common materials include rubber, silica gel, polyurethane, etc.

[0035] Working principle:

[0036] When the fork part 4 forks up the goods shelf 3 and it is necessary to clamp and fix the upright column of the goods shelf 3, the driving mechanism 204 is started, and the driving motor 2042 starts. It will generate torque and drive the driving synchronous pulley 2043 to rotate. Through the synchronous belt 2045, this rotational motion is smoothly transmitted to the driven synchronous pulley 2044, and then the double-headed screw 203 is driven to rotate. The driving mechanism 204 drives the double-headed screw 203 to rotate. Since the thread directions at both ends of the double-headed screw 203 are opposite, when the double-headed screw 203 rotates, the two threaded sleeves 205 will move towards the middle or towards both ends along the double-headed screw 203 simultaneously. The movement of the threaded sleeve 205 will drive the sliding plate 206 and the clamping plate 207 vertically installed on the sliding plate 206 to move together. When the two clamping plates 207 move towards the middle, the clamping and fixing of the upright column of the goods shelf 3 are realized; when the two clamping plates 207 move towards both ends, the clamping of the upright column of the goods shelf 3 is released. The clamping plate 207 is used to fix or clamp the goods shelf 3 to ensure its stability and prevent it from moving or vibrating during the processing. The limiting plate 208 is vertically installed on the clamping plate 207, and its function is to limit the goods shelf 3 in the vertical direction to further prevent the goods shelf 3 from shaking during the movement.

[0037] The fork part 4 supports the bottom of the goods shelf 3, and the auxiliary support mechanism 2 clamps and fixes the middle section of the upright column of the goods shelf 3, forming a double support structure. The clamping and fixing of the upright column of the goods shelf 3 by the auxiliary support mechanism 2 can limit the movement of the goods shelf 3 in the horizontal direction. Especially when turning or encountering external force interference, it can effectively prevent the goods shelf 3 from tilting and improve the overall stability. The utility model can effectively increase the stability of the goods shelf during handling, reduce the risk of the goods shelf shaking or tipping over. A stable handling process can reduce the possibility of goods falling or the goods shelf tipping over, thereby improving the safety of the workplace and reducing the occurrence of accidents. The AGV intelligent handling robot of the utility model can adapt to different types and sizes of goods shelves 3, improving its versatility and adaptability, and also ensuring stability under various working conditions.

[0038] The above-described embodiments only represent certain implementation manners of the utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent; it should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model; therefore, the protection scope of the utility model patent should be subject to the appended claims.
