Description

Technical Field

[0001] The utility model relates to the field of barcode scanning, in particular to a commodity barcode scanning device. Background Art

[0002] Product barcodes improve operational efficiency and accuracy in e-commerce production lines. When entering the warehouse, barcode scanning enters product information into the inventory management system to ensure accurate inventory. Inventory management optimizes configuration by regularly scanning inventory. When picking orders, scanning barcodes ensures that products match orders and reduces errors. In the packaging and shipping process, barcodes verify order integrity and ensure correct packaging and shipping. In logistics tracking, barcodes update logistics information in real time and provide accurate tracking.

[0003] Existing barcode scanning devices are divided into handheld and fixed types. Among them, fixed barcode scanning devices are often used to scan product barcodes on assembly lines. During the scanning work, the fixed barcode scanning device needs to be kept in the turned-on state all the time, and it is easy to overheat and cause shutdown after working for a long time; while the handheld scanning device needs to manually operate the switch button to realize the scanning operation of the product barcode, and does not need to keep working all the time, but the scanning efficiency is low. Therefore, we propose a product barcode scanning device that has both high scanning efficiency and long working time. Utility Model Content

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1-Figure 8 As shown, this embodiment proposes a commodity barcode scanning device, including a movable frame 2 mounted on a commodity conveyor belt 1, a chassis 3 arranged parallel to the commodity conveyor belt 1 is fixedly installed in the movable frame 2, a turntable 4 is rotatably arranged on the upper end of the chassis 3, four evenly distributed receiving grooves 5 are opened on the circumferential surface of the turntable 4, and the receiving grooves 5 are arranged through from top to bottom. In this embodiment, the width of the receiving grooves 5 matches the width of the commodity conveyor belt 1, so that the commodities can enter the receiving grooves 5. The positions of the four receiving grooves 5 are arranged as a loading station, a scanning station, a unloading station and a temporary rest station in sequence along the rotation direction of the turntable 4. The commodity conveyor belt 1 is used to transport commodities to the upper The material station, the turntable 4 rotates to transport the goods to the scanning station and the unloading station in sequence, and the product conveyor belt 1 is also used to transport the goods at the unloading station to the next product material link; a scanning component 6 is arranged directly above the corresponding scanning station on the movable frame 2, and the scanning component 6 is used to scan the barcode of the product at the scanning station, and a push switch 61 electrically connected to the upper end of the scanning component 6 is arranged, and a pressure plate 7 sliding in the vertical direction is arranged directly above the push switch 61. When the product is transported to the scanning station, the pressure plate 7 moves downward in the vertical direction and presses the push switch 61 to start the scanning component 6 to complete the scanning operation of the product barcode.

[0030] On the basis of the above scheme, if the goods have not entered the loading station, the entire turntable 4 needs to be in a stationary state so that the goods can enter the loading station smoothly. Therefore, in this embodiment, a detection component for detecting whether the goods have entered the loading station is arranged inside the accommodating groove 5, and after the detection component successfully detects that the goods have entered the loading station, the turntable 4 needs to be linked to rotate. Specifically, the inside of the accommodating groove 5 is equipped with a movable plate 51 that slides radially along the turntable 4, and a spring 52 is installed between the movable plate 51 and the bottom wall of the accommodating groove 5. A connecting rod 53 is also fixedly installed at one end of the movable plate 51 close to the turntable 4. The connecting rod 53 movably passes through the turntable 4 and extends to the inside of the turntable 4, and a toothed plate 54 is fixedly installed at the end of the connecting rod 53; the center of the turntable 4 is rotatably connected to the rotating shaft 42 through a bearing, and a toothed ring 43 matching the toothed plate 54 is installed on the circumferential surface of the rotating shaft 42 at a position corresponding to the toothed plate 54. When there is no product in the loading station, the spring 52 pushes the movable plate 51 to move in the direction away from the gear ring 43, so that the gear ring 43 and the tooth plate 54 are separated. At this time, the turntable 4 is in a stationary state; when the product enters the loading station along the product conveyor belt 1, the product exerts an inward force on the movable plate 51, and the movable plate 51 is subjected to the force and drives the tooth plate 54 to move in the direction close to the gear ring 43. The tooth plate 54 and the gear ring 43 are engaged with each other, so that the turntable 4 and the rotating shaft 42 are connected into a whole, and the rotating shaft 42 is driven to rotate by an external driving component, so that the synchronous rotation of the turntable 4 is realized, and the product is then conveyed to the scanning station.

[0031] In this embodiment, the external driving component adopts a pulley motor group. Specifically, a large pulley is fixedly sleeved on the circumferential surface of the rotating shaft 42, and the large pulley is connected to a small pulley through a V-belt transmission. The axis of the small pulley is fixedly connected to the motor shaft of the servo motor, and the servo motor is fixedly installed on the movable frame 2.

[0032] Since the turntable 4 generates inertia during the rotation process, the inertia will affect the rotation accuracy of the turntable 4, and thus it is impossible to ensure that the goods move accurately to the scanning station. For this reason, a locking component is provided in the present embodiment to offset the inertia during the rotation of the turntable 4. Specifically: the chassis 3 includes a bottom circular plate 31, and two arc-shaped baffles 32 are symmetrically installed at the upper edge of the bottom circular plate 31. The inner wall of the arc-shaped baffle 32 slides and rubs with the outer circumferential surface of the turntable 4. An opening 33 matching the accommodating groove 5 is formed between the two arc-shaped baffles 32. The inner wall of the arc-shaped baffle 32 is provided with a first guide groove 321, and the bottom wall of the first guide groove 321 is provided with a through hole 322, which extends to the outer circumferential surface of the arc-shaped baffle 32; a limiting rod 55 is installed at one end of the movable plate 51 away from the tooth plate 54, and the limiting rod 55 movably passes through the first guide groove 321 and the through hole 322, and the number of the limiting rods 55 is the same as the number of the through holes 322. When there is no product in the loading station, the limit rod 55 passes through the through hole 322, so that the turntable 4 and the arc-shaped baffle 32 are connected as a whole. At this time, the turntable 4 cannot rotate and remains in a stationary state; when the product applies a force to the movable plate 51 and causes the movable plate 51 to move in the direction close to the tooth plate 54, the end of the limit rod 55 at the loading station position immediately disengages from the through hole 322 and moves in the direction close to the first guide groove 321. When the tooth plate 54 and the gear ring 43 are fully engaged, the end of the limit rod 55 just enters the first guide groove 321. At this time, the end of the limit rod 55 slides in the first guide groove 321. When the limit rod 55 moves to the through hole 322 corresponding to the scanning station position, the end of the limit rod 55 enters the through hole 322 corresponding to the scanning station position. At this time, the tooth plate 54 and the gear ring 43 are separated, and the turntable 4 is in a stationary state again. It should be noted that when the goods enter the loading station again, the turntable 4 needs to be rotated again. At this time, the limit rod 55 inserted into the through hole 322 will re-enter the first guide groove 321 under the influence of the rotation force. In order to reduce friction, the end of the limit rod 55 is set to a spherical surface.

[0033] When the commodity enters the scanning station, the second connecting rod 71 moves downward in the vertical direction and presses the push switch 61. After the push switch 61 is pressed, an electrical signal is transmitted to the scanning component 6. The scanning component 6 works after receiving the electrical signal. In order to improve the coherence of the movement of related components and reduce the manufacturing cost, in this embodiment, the rotational movement of the rotating shaft 42 is combined with the second guide groove 74 and the guide block 75 to realize the linear movement of the pressing plate 7 in the vertical direction. Specifically, the pressing plate 7 is fixedly connected to the second connecting rod 71. The other end of the second connecting rod 71 is fixedly connected to the outer circumferential surface of 72, 72 is movably inserted in the rotating shaft 42, and the second connecting rod 71 is slidably assembled on the vertical guide plate 73 along the vertical direction, and the vertical guide plate 73 is fixedly mounted on the movable frame 2; a second guide groove 74 is opened on the inner wall of the rotating shaft 42, and the second guide groove 74 is composed of four horizontal parts 741 and four recessed parts 742 spliced ​​end to end, and a guide block 75 is installed on the outer circumferential surface of 72, and the guide block 75 is slidably assembled in the second guide groove 74. When there is no commodity in the loading station, the guide block 75 is at the junction of one of the horizontal parts 741 and the recessed part 742. When the commodity enters the scanning station, the guide block 75 just enters the adjacent recessed part 742 from the horizontal part 741. At this time, 72 moves downward in the vertical direction, so that the pressing plate 7 contacts the push switch 61, and the commodity barcode scanning operation is completed; when the commodity enters the unloading station, the guide block 75 enters the next horizontal part 741 from the recessed part 742. At this time, the pressing plate 7 moves upward in the vertical direction, and the scanning component 6 stops working.

[0034] In order to improve the stability of the turntable 4 during rotation, in this embodiment, a lap edge 41 is fixedly mounted on the outer circumferential surface of the turntable 4 , and the lap edge 41 is slidably assembled on the upper end surface of the arc-shaped retaining bar 32 .
