Description

Technical Field

[0001] This utility model relates to the field of barcode scanning and identification technology, and more specifically, to a high-precision barcode scanning and identification device for logistics supply chain. Background Technology

[0002] In the logistics supply chain, logistics transshipment is an important component. When a package is transported to the transshipment center, it will be scanned by a barcode scanning device to collect the package's transportation information.

[0003] The position of the barcode scanner is usually fixed. Various packages move forward on the conveyor belt and pass through the barcode scanner to collect the barcode. However, different packages have different sizes. When a large number of packages are placed on the conveyor belt, some packages are located in a more remote position. When the package is small, it cannot be recognized by the scanner when it moves under the barcode scanner. Therefore, a structure is designed to solve the problem that the barcode recognition device cannot recognize packages in a remote position. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a high-precision barcode scanning and identification device for logistics supply chains, thereby improving the scanning accuracy of the device through structural design.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The high-precision barcode scanning and identification device for the logistics supply chain includes a conveyor belt and a barcode scanner fixedly connected to the conveyor belt. Both sides of the conveyor belt are rotatably connected to inclined blocking plates. The distance between the ends of adjacent blocking plates near the barcode scanner is less than the distance between the ends of adjacent blocking plates away from the barcode scanner. A plurality of connecting plates are rotatably connected to the conveyor belt. When the plurality of connecting plates are parallel to the conveyor belt, the plurality of blocking plates rotate in a direction away from each other.

[0006] The present invention is further configured such that: the connecting plate is symmetrically arranged along the central axis of the conveyor belt length direction, a conductive plate is fixedly connected to the side of the connecting plate near the conveyor belt, and the distance between the connecting plate and the blocking plate is less than the distance between the connecting plate and the end of the conveyor belt away from the barcode scanner.

[0007] The present invention is further configured such that: a contact plate detachably connected to a conductive plate is fixedly connected to the bottom surface of the conveyor belt, and the contact plate is made of a conductive material.

[0008] The present invention is further configured such that: an adsorption sheet is fixedly connected to the side wall of the blocking plate and is detachably connected to the blocking plate; the adsorption sheet is configured as an electromagnet; a magnetic block is fixedly connected to the side of the blocking plate near the adsorption sheet; and the adsorption sheet and the contact plate are electrically connected by a connecting wire.

[0009] The present invention is further configured such that: a placement groove for rotating the connecting plate is provided on the conveyor belt, and a through groove for sliding connection with the conductive plate is provided on the inner wall of the placement groove, and the conductive plate passes through the through groove and is detachably connected to the contact plate.

[0010] The present invention is further configured such that: a receiving groove is provided at the rotatable connection between the inner wall of the placement groove and the connecting plate, and a torsion member is fixedly connected in the receiving groove, with both ends of the torsion member being fixedly connected to the inner wall of the receiving groove and the connecting plate, respectively.

[0011] In summary, this utility model has the following beneficial effects: the baffle plate provides guidance for the movement of packages on the conveyor belt, and by setting the tilt direction of the baffle plate, the packages can move under the guidance of the baffle plate to the bottom of the barcode scanner, ensuring that the barcode scanner can stably scan small packages. When larger packages push the connecting plate at the same time, the baffle plates will move in a direction away from each other, thereby increasing the channels on the conveyor belt for packages to pass through and ensuring the stable movement of large packages.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] This logistics supply chain uses high-precision barcode scanning and identification devices, such as... Figure 1 , Figure 2 and Figure 5 As shown, the device includes a conveyor belt 1 and a barcode scanner 2 fixed to the conveyor belt 1 by bolts. Both sides of the conveyor belt 1 are rotatably connected to inclined baffle plates 3. The distance between the ends of adjacent baffle plates 3 that are closer to the barcode scanner 2 is less than the distance between the ends of adjacent baffle plates 3 that are farther away from the barcode scanner 2. The baffle plates 3 are used to guide the movement of the package, so that the package can move along the baffle plates 3 towards the barcode scanner 2. Even packages that are placed in a relatively remote position can be moved to the bottom of the barcode scanner 2, thus ensuring the scanning rate of the device.

[0021] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, several connecting plates 4 are rotatably connected to the conveyor belt 1. When the connecting plates 4 are parallel to the conveyor belt 1, the several blocking plates 3 rotate in a direction away from each other. When a large package is encountered, the large package will exert a pushing force on the connecting plates 4 at the same time, causing them to rotate towards the barcode scanner 2. When the connecting plates 4 rotate to the same horizontal plane as the top surface of the conveyor belt 1, the blocking plates 3 will rotate in a direction away from each other, thereby increasing the space on the conveyor belt 1 for large packages to pass through. However, smaller packages cannot push two connecting plates 4 at the same time, so the blocking plates 3 cannot rotate, allowing the blocking plates 3 to still play a guiding role for the packages.

[0022] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the connecting plate 4 is symmetrically arranged along the central axis of the conveyor belt 1. A conductive plate is attached to the side of the connecting plate 4 closest to the conveyor belt 1. The distance between the connecting plate 4 and the blocking plate 3 is less than the distance between the connecting plate 4 and the end of the conveyor belt 1 away from the barcode scanner 2. This shortens the time required for the package to pass through the blocking plate 3 after passing through the connecting plate 4, allowing the package to pass through the blocking plate 3 before the blocking plate 3 returns to its initial position, thus ensuring the stable movement of the package.

[0023] like Figure 1 , Figure 2 and Figure 5As shown, an adsorption sheet 5 is detachably connected to the side wall of the baffle plate 3. The adsorption sheet 5 is an electromagnet. A magnetic block 6 is attached to the side of the baffle plate 3 near the adsorption sheet 5. In the initial state, the electromagnet is de-energized, so the adsorption sheet 5 cannot apply a pulling force to the baffle plate 3, so the baffle plate 3 can always be in an inclined state. When a current is generated in the adsorption sheet 5, the electromagnet generates an attractive force that can attract the baffle plate 3, so that the baffle plate 3 can rotate under the action of the adsorption sheet 5, thereby increasing the space on the conveyor belt 1 for the package to pass through.

[0024] like Figures 1-6 As shown, a contact plate 7 is detachably connected to a conductive plate and bonded to the bottom surface of the conveyor belt 1. One conductive plate is connected to two sets of contact plates 7 to ensure the stable formation of the circuit. The contact plate 7 is made of copper with conductive properties. The adsorption sheet 5 and the contact plate 7 are electrically connected through the connecting wire 8. In the initial state, the connecting plate 4 is set perpendicular to the conveyor belt 1. When the package applies a pushing force to the connecting plate 4 to make it rotate to be set horizontally with the conveyor belt 1, the circuit is connected, so that current flows through the adsorption sheet 5 to generate magnetic force. The magnetic force drives the blocking plate 3 to rotate.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, a support frame is welded to the side wall of the conveyor belt 1, and a spring is glued to the support frame. The other end of the spring is glued to the baffle plate 3. When the adsorption sheet 5 exerts an adsorption force on the baffle plate 3, the spring will be subjected to the pressure exerted on it by the baffle plate 3, resulting in compression deformation. When the circuit is disconnected, the adsorption force exerted by the adsorption sheet 5 on the baffle plate 3 disappears, and the spring will reset under the action of its own elastic deformation performance and exert a pushing force on the baffle plate 3 to restore it to its initial position. Moreover, the supporting force of the spring on the baffle plate 3 is greater than the pushing force exerted on the baffle plate 3 by the wrapper, thereby reducing the situation where the baffle plate 3 rotates under external force and ensuring the stable use of the structure.

[0026] like Figure 1 , Figure 4 and Figure 6 As shown, the conveyor belt 1 has a placement groove 9 for the connecting plate 4 to rotate. The depth of the placement groove 9 is the same as the thickness of the connecting plate 4, which ensures that the connecting plate 4 can be on the same plane as the conveyor belt 1 after rotation, reducing the situation where the connecting plate 4 is perpendicular to the conveyor belt 1 and hinders the movement of the package. The inner wall of the placement groove 9 has a through groove 10 that is slidably connected to the conductive plate. The conductive plate passes through the through groove 10 and is detachably connected to the contact plate 7. The conductive plate can pass through the through groove 10 and communicate with the contact plate 7, ensuring stable circuit connection.

[0027] like Figure 1 and Figure 6As shown, a receiving groove 11 is provided at the rotatable connection between the inner wall of the placement groove 9 and the connecting plate 4. A torsion member 12 is fixedly connected in the receiving groove 11. The torsion member 12 is a torsion spring. The two ends of the torsion member 12 are respectively bonded to the inner wall of the receiving groove 11 and the connecting plate 4. During the movement of a large package, it will exert a pushing force on the connecting plate 4, causing it to rotate towards the placement groove 9. The rotation of the connecting plate 4 will exert pressure on the torsion member 12, causing it to undergo torsional deformation. After the package passes over the connecting plate 4, the pressure on the torsion member 12 disappears and it resets under the action of its own elastic deformation performance. At this time, the connecting plate 4 will be pushed by the torsion member 12 and rotate again to a state perpendicular to the conveyor belt 1.

[0028] Working principle: When a small package moves on the conveyor belt 1, the blocking plate 3 guides the package's movement direction, causing it to move closer to the barcode scanner 2. When a large package moves on the conveyor belt 1, the package exerts a pushing force on the connecting plate 4, causing it to rotate and come into contact with the bottom surface of the placement slot 9. At this time, the conductive plate passes through the through slot 10 and comes into contact with the contact plate 7. At this time, the adsorption sheet 5 generates a current inside, thereby generating a magnetic attraction force. The adsorption sheet 5 then exerts a pulling force on the connecting plate 4, causing it to move closer to the adsorption sheet 5. This increases the channel on the conveyor belt 1 for large packages to pass through, ensuring the stable transport of packages.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
