[0002] In the field of logistics sorting, efficiently and accurately completing the sorting, code scanning and feeding process of logistics pieces is crucial for the smoothness and accuracy of the entire logistics operation. For example, for some logistics pieces with small quantities, irregular shapes or special processing requirements, manual classification is performed one by one according to classification principles. For a large number of standardized logistics pieces, an automatic sorting device such as an automatic sorting machine is used. The logistics pieces are transported to the sorting machine through a conveying line, and after sorting is completed, each logistics piece is grabbed by a feeding manipulator and transferred to a code scanning station for code scanning operation to obtain detailed information of the logistics piece.

[0004] However, the mechanical arm is limited by its structural defects, resulting in slow grabbing speed and inability to meet large-scale and high-efficiency logistics sorting requirements. As a result, it is easy to cause the accumulation of logistics pieces at the code scanning station, affecting the subsequent code scanning and feeding process. In addition, after the mechanical arm places the logistics pieces at the code scanning station, it needs to wait for the code scanning device to obtain the information of the logistics pieces, and then transfer the logistics pieces to the feeding position, making the motion control path of the mechanical arm complex, increasing the control difficulty and affecting the feeding efficiency of the logistics pieces.

DETAILED DESCRIPTION

[0022] The specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0023] As Figures 1-4 shown, the utility model embodiment proposes a kind of material grabbing equipment for logistics code scanning station, in the process of logistics piece code scanning feeding, reduce the transfer difficulty of logistics piece on multiple stations, improve the feeding efficiency of logistics piece.

[0024] As Figure 1 shown, a kind of logistics grabbing equipment for logistics code scanning station includes material distribution platform 1, code scanning station 2 and feeding conveying table 3 in turn in a word and is arranged, and feeding component 4.Labor component is arranged above code scanning station 2, and feeding component 4 is configured to use grabbing mechanism 42 to move logistics piece located on material distribution platform 1 to code scanning station 2 and stop, then is sent to feeding conveying table 3.

[0025] As Figure 2As shown, the grabbing mechanism 42 includes a suction cup assembly 421, a crank slider mechanism 422 and a power component 423. The suction cup assembly 421 is connected to the output end of the power component 423 through the crank slider mechanism 422. The crank slider mechanism 422 can convert the rotary motion of the power component 423 into the linear reciprocating motion of the suction cup assembly 421, and through precise mechanical structure design, the moving stroke and position of the suction cup assembly 421 can be accurately controlled, so as to realize accurate grabbing of the logistics piece.

[0026] The logistics grabbing equipment for the logistics code scanning station according to the embodiment of the utility model arranges the material distribution platform 1, the code scanning station 2 and the feeding conveying table 3 in a straight line, constructs very smooth operation streamline, the grabbing mechanism 42 moves logistics piece from the material distribution platform 1 to the code scanning station 2 according to the order, after completing code scanning, again transfers to the feeding conveying table 3, the whole process is completed in one breath, greatly reduces the transfer time and distance of logistics piece between different stations, effectively improves the overall operation efficiency, greatly reduces the transfer difficulty of logistics piece on multiple stations, improves the feeding efficiency of logistics piece.

[0027] As shown, Figure 3 The suction cup assembly 421 is configured to grab logistics pieces on the material distribution platform 1 at the first grabbing position 4211, grab logistics pieces on the code scanning station 2 at the second grabbing position 4212, and transfer from one side of the material distribution platform 1 to one side of the feeding conveying table 3 under the driving of the power component 423. The first grabbing position 4211 releases the sucked logistics pieces on the code scanning station 2, and the second grabbing position 4212 releases the sucked logistics pieces on the feeding conveying table 3.

[0028] The double grabbing position design enables the suction cup assembly 421 to simultaneously perform two different stages of material grabbing and releasing actions. While the first grabbing position 4211 grabs logistics pieces from the material distribution platform 1, the second grabbing position 4212 can grab the code scanned logistics pieces from the code scanning station 2 and transfer to the feeding conveying table 3, greatly reducing the waiting time of material transfer and realizing parallel operation of material transfer, making the overall logistics code scanning operation process more compact and efficient. Compared with single grabbing position equipment, more logistics pieces can be processed per unit of time.

[0029] The two grabbing positions correspond to the material distribution platform 1 and the code scanning station 2 respectively, and the clear division of labor makes the logistics piece flow path more clear and orderly. The first grabbing position 4211 focuses on obtaining code scanning materials from the material distribution platform 1, and the second grabbing position 4212 is responsible for transferring the code scanned materials to the feeding conveying table 3, avoiding confusion and cross interference of materials in the flow process, reducing the risk of collision, extrusion and other damage between logistics pieces, and ensuring the integrity of the logistics pieces.

[0030] In addition, the suction cup assembly 421 works in coordination with the two grabbing positions, so that the device is more balanced during operation. When the power component 423 drives the suction cup assembly 421 to move, the two grabbing positions work simultaneously, which reduces the unbalanced weight or shaking that may occur when a single grabbing position works, so that the device runs more smoothly, prolongs the service life of the device, and reduces the maintenance cost of the device.

[0031] As shown in Figure 4 , the first grabbing position 4211 and the second grabbing position 4212 are each provided with a plurality of suction heads. The plurality of suction heads are dispersed in the first grabbing position 4211 and the second grabbing position 4212, and when grabbing the material, the plurality of suction heads can provide suction force to the material from multiple points, so that the material is more evenly stressed during grabbing and transferring. For irregularly shaped or unevenly distributed material, the risk of falling, tilting, etc. caused by uneven stress during transfer is effectively reduced, ensuring that the material is stably and safely transferred from the material distribution platform 1 to the code scanning station 2, and from the code scanning station 2 to the feeding conveyor 3. For example, the four suction heads are arranged in a rectangular shape in the first grabbing position 4211.

[0032] According to some preferred embodiments of the present application, as shown in Figure 2 , the feeding component 4 includes a base 41 and a grabbing mechanism 42. The grabbing mechanism 42 is installed above the material distribution platform 1 through the base 41. In this way, the space above the material distribution platform 1 is fully utilized, avoiding the need to occupy additional space around the material distribution platform 1 to accommodate the grabbing mechanism 42, so that the layout of the device is more compact, and in a limited logistics working site, the device can be better integrated, reducing the site occupation, which is conducive to the rational planning and efficient use of the logistics operation area, improving the space utilization of the site.

[0033] As shown in Figure 3 , in combination with Figure 4 , the crank slider mechanism 422 includes a connecting handle 4221, a pull rod 4222, a first guide rail 4223, and a sliding seat 4224. One end of the connecting handle 4221 is connected to the output end of the power component 423. The other end of the connecting handle 4221 is connected to the pull rod 4222. The first guide rail 4223 is installed on the base 41 and is arranged in a direction from the material distribution platform 1 to the code scanning station 2. The sliding seat 4224 is embedded in the first guide rail 4223. The sliding seat 4224 is provided with a guide seat 4225. The guide seat 4225 is provided with a guide groove. The guide groove is perpendicular to the first guide rail 4223. The pull rod 4222 is embedded in the guide groove. The suction cup assembly 421 is connected to the pull rod 4222.

[0034] Through the coordinated operation of components such as the connecting handle 4221, pull rod 4222, first guide rail 4223, and slide 4224, the circular motion of the power component 423 can be precisely converted into the linear motion of the suction cup assembly 421 along a specific direction. The first guide rail 4223 is arranged along the direction from the material distribution platform 1 to the barcode scanning station 2, ensuring that the movement trajectory of the suction cup assembly 421 driven by the slide 4224 is stable and accurate. This allows materials to move strictly along a predetermined path from the material distribution platform 1 to the barcode scanning station 2 during the transfer process, greatly improving the accuracy of material gripping and transfer and reducing deviations.

[0035] The pull rod 4222 is embedded in the guide groove of the guide seat 4225, and the guide groove is arranged perpendicular to the first guide rail 4223. When the power component 423 drives the connecting handle 4221 to move, the sliding of the pull rod 4222 in the guide groove can buffer the impact caused by changes in power or impact to a certain extent. If the output force of the power component 423 fluctuates instantaneously, the relative sliding of the pull rod 4222 in the guide groove can absorb some energy, avoiding excessive impact on the suction cup assembly 421 and the material.

[0036] In application scenarios involving barcode scanning and loading of stacked logistics items, such as Figure 1 As shown, a lifting device 5 is installed at the bottom of the sorting platform 1. The lifting device 5 is configured to lift the sorting platform 1 layer by layer as the gripping mechanism 42 grips the materials. As the gripping mechanism 42 grips the materials layer by layer, the lifting device 5 lifts the sorting platform 1 layer by layer, always maintaining the top layer of materials in line with the optimal gripping position of the gripping mechanism 42. This avoids the need for the gripping mechanism 42 to constantly adjust its height during the gripping process, reduces the action time of each gripping action, improves the overall gripping efficiency, and thus speeds up the entire loading and sorting process.

[0037] According to some preferred embodiments of this utility model, the barcode scanning station 2 is equipped with a transparent tray for supporting logistics items. The transparent tray ensures that the logistics items are in a flat and stable state during barcode scanning. Furthermore, the transparent material does not interfere with the light emitted and received by the barcode scanning device; light can penetrate the tray without obstruction, ensuring that the barcode scanning device can clearly and accurately read the logistics code information, thereby improving scanning accuracy and reducing sorting errors caused by scanning mistakes.

[0038] In this embodiment of the present invention, a logistics gripping device for a logistics barcode scanning station is used such that the logistics items are first placed on the sorting platform 1, and the gripping mechanism 42 of the loading component 4 is located above the sorting platform 1. The first gripping position 4211 of the suction cup assembly 421 in the gripping mechanism 42 is equipped with multiple suction heads, which begin to work, using suction to grip the logistics items on the sorting platform 1. At this time, the power component 423 is activated, driving the connecting handle 4221 to move.

[0039] The movement of the connecting handle 4221 is transmitted through the pull rod 4222, and since the pull rod 4222 is embedded in the guide groove of the guide seat 4225 arranged vertically to the first guide rail 4223, the circumferential movement of the connecting handle 4221 is converted into the linear movement of the sliding seat 4224 along the first guide rail 4223 from the direction of the material distribution platform 1 to the direction of the code scanning station 2, thereby driving the suction cup assembly 421 to move. The logistics piece grabbed by the first grabbing position 4211 is transferred to above the code scanning station 2, and then the suction head of the first grabbing position 4211 releases the logistics piece, so that the logistics piece is parked on the code scanning station 2 for code scanning operation.

[0040] At the same time when the first grabbing position 4211 transfers the material to the code scanning station 2, the second grabbing position 4212 of the suction cup assembly 421 also works. The plurality of suction heads of the second grabbing position 4212 grab the logistics piece that has completed code scanning on the code scanning station 2. As the suction cup assembly 421 continues to move along the predetermined path under the drive of the power component 423, the second grabbing position 4212 transfers the scanned logistics piece sucked to above the feeding conveying table 3, and then releases the logistics piece, so that the logistics piece falls on the feeding conveying table 3, and the whole transfer process of the material from the material distribution platform 1 to the feeding conveying table 3 through the code scanning station 2 is completed, so as to realize the continuous and efficient operation of the logistics code scanning station through the circulation.

[0041] The utility model is not limited to the specific technical solutions described in the above embodiment, and in addition to the above embodiment, the utility model can also have other implementation manners. For those skilled in the art, any modification, equivalent replacement, improvement, etc. formed within the spirit and principle of the utility model should be included in the protection scope of the utility model.
