Description

Technical Field

[0001] This utility model relates to the field of logistics verification technology, and in particular to a UHF verification device. Background Technology

[0002] UHF verification equipment refers to verification equipment related to ultra-high frequency radio frequency identification technology. It is mainly used to read, identify and process data from UHF RFID tags to achieve automated management and monitoring of items, facilitate verification by managers, greatly save labor costs and improve work efficiency. It is mainly used for single-item-level item identification, such as inbound and outbound management and product inventory in industries such as clothing, leather goods, alcohol, and power.

[0003] Chinese Patent CN217946430U discloses an RFID receiving and shipping verification channel machine, including a housing, a conveying device, a weighing device, a pushing device, and a processor. The conveying device consists of three sets. The weighing device is fixedly mounted on the housing. All three sets of conveying devices are located around the weighing device and are fixedly connected to the housing. Any one of the conveying devices is used to transfer goods onto the weighing device. A reader is fixedly mounted on the housing and is used to read tags on the goods. The pushing device is located on one side of the weighing device. The weighing device measures the weight of the goods on it, and the pushing device, based on the results from the reader and the weighing device, pushes the goods on the weighing device onto one of the two conveying devices not used to transfer goods onto the weighing device. This device can compare the number of tags with the weight of the goods through the weighing device, thereby determining whether the quantity of goods matches the number of tags, making receiving and shipping more accurate.

[0004] However, the above technical solution has the following shortcomings: when the equipment pushes the box from the platform to the conveyor belt through the electric cylinder, electric slide and L-shaped push plate, the force-bearing area between the L-shaped push plate and the box is small and the pushing force is unevenly distributed. This not only makes it easy for the box to tilt and fail to be pushed onto the conveyor belt, but also makes it easy for the box to be severely deformed, reducing the practicality of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a UHF verification device that can apply force evenly and stably when pushing the box, ensuring stability during pushing and avoiding serious deformation of the box.

[0006] The technical solution of this utility model is a UHF verification device, including a support base and a pushing device; the support base is provided with a first conveyor belt, a second conveyor belt and a third conveyor belt, and a mounting frame is provided on the support base, with a connecting seat below the mounting frame; the pushing device consists of two devices, which are respectively located above the first conveyor belt and to the side of the connecting seat, and include a horizontally arranged cylinder, a fixed plate driven and connected to the cylinder, four connecting plates symmetrically distributed on the fixed plate, a sliding rod that passes through and is slidably connected to the connecting plate, a push plate coaxially arranged on the sliding rod, and springs with their two ends respectively arranged on the push plate and the connecting plate; an elastic pad is provided on the push plate.

[0007] Preferably, the sliding rod is provided with four sliders arranged in a circular array, and the inside of the connecting plate is provided with grooves for the sliders to slide.

[0008] Preferably, the connecting seat is provided with a weighing component, which includes a pressure sensor disposed inside the connecting seat, a placement platform disposed on the pressure sensor, and four auxiliary support members symmetrically distributed inside the connecting seat; the placement platform is disposed on the auxiliary support members.

[0009] Preferably, a reader / writer is provided on the mounting bracket.

[0010] Preferably, the support base is provided with two uprights, and the uprights are provided with a lifting mechanism that drives the pushing device on one side to move vertically.

[0011] Preferably, the lifting mechanism includes a motor mounted on the upright, a threaded rod rotatably mounted on the upright, guide rods vertically distributed on the upright, and a lifting seat slidably connected to the guide rods; the motor and the threaded rod are driven together, the threaded rod and the lifting seat are threaded together, and a pushing device is mounted on the lifting seat.

[0012] Preferably, a base is provided on the side of the support, and a pushing device is provided on the base on the other side.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention utilizes a pusher device to apply uniform force to all four corners of the box simultaneously.

[0021] Example 1

[0022] like Figures 1-5 As shown, the UHF verification device proposed in this embodiment includes a support base 1 and a pushing device; the support base 1 is provided with a first conveyor belt 2, a second conveyor belt 4 and a third conveyor belt 5, the support base 1 is provided with a mounting frame 6, and a connecting seat 3 is provided below the mounting frame 6.

[0023] The number of pushing devices is two, which are respectively set above the first conveyor belt 2 and to the side of the connecting seat 3. They include a horizontally set cylinder 16, a fixed plate 17 driven and connected to the cylinder 16, four connecting plates 18 symmetrically distributed on the fixed plate 17, a sliding rod 19 that passes through and is slidably connected to the connecting plate 18, a push plate 20 coaxially set on the sliding rod 19, and a spring 22 with its two ends respectively set on the push plate 20 and the connecting plate 18; the push plate 20 is provided with an elastic pad 21.

[0024] The sliding rod 19 is provided with four sliders 23 arranged in a circular array. The connecting plate 18 is provided with grooves for the sliders 23 to slide. The sliders 23 and the grooves are provided to guide and limit the movement of the sliding rod 19, so as to prevent the sliding rod 19 from causing the push plate 20 to deflect and affecting the stability of the pushing action.

[0025] In this embodiment, when it is necessary to push the container loaded with goods to the second conveyor belt 4 or the third conveyor belt 5, the fixed plate 17 can be moved by activating the cylinder 16 at the corresponding position. The fixed plate 17 drives the connecting plate 18 to move, and the connecting plate 18 drives the sliding rod 19 and the push plate 20 to move until the elastic pad 21 of the push plate 20 and the surface of the container come into contact with each other. As the connecting plate 18 continues to move, the push plate 20 first compresses the spring 22 through the sliding rod 19, and then pushes the container to move. The four push plates 20 act on the four corners of the container, which not only applies force evenly to the container, but also reduces damage to the surface of the container in conjunction with the elastic pad 21 and the spring 22, and has good practicality.

[0026] Example 2

[0027] like Figures 1-3 As shown, the UHF verification device proposed in this embodiment, compared with the first embodiment, has a reader / writer 7 installed on the mounting frame 6 and a weighing component installed on the connecting seat 3. The weighing component includes a pressure sensor 9 installed inside the connecting seat 3, a placement platform 8 installed on the pressure sensor 9, and four auxiliary support members 10 symmetrically distributed inside the connecting seat 3. The placement platform 8 is installed on the auxiliary support members 10, which are used to ensure the stability of the placement platform 8.

[0028] In this embodiment, after the box is conveyed to the placement platform 8 of the connecting seat 3 by the first conveyor belt 2, the reader 7 reads and counts the labels on the materials inside the box to record the quantity of materials. At the same time, the pressure sensor 9 weighs the box and the materials, and then transmits the signal to enable external equipment to analyze and process the data, comparing the counterweight of the standard quantity of materials with the actual weight. If the comparison result is normal, the box is conveyed to the second conveyor belt 4. If the comparison result is abnormal, the box is conveyed to the third conveyor belt 5, and then the staff opens the box for inspection.

[0029] Example 3

[0030] like Figure 1 and Figure 4 As shown, the UHF verification device proposed in this embodiment, compared with the first embodiment, has two uprights 11 on the support base 1. The uprights 11 are equipped with a lifting mechanism that drives the pushing device on one side to move vertically. The lifting mechanism includes a motor 12 on the uprights 11, a threaded rod 13 rotatably mounted on the uprights 11, a guide rod 15 vertically distributed on the uprights 11, and a lifting seat 14 slidably connected to the guide rod 15. The motor 12 and the threaded rod 13 are driven to be connected, the threaded rod 13 and the lifting seat 14 are threaded to be connected, and the pushing device is mounted on the lifting seat 14.

[0031] A base 24 is provided on the side of the support 1, and a pushing device is provided on the base 24 on the other side.

[0032] In this embodiment, when the box needs to be transported to the second conveyor belt 4, the motor 12 is first started to drive the threaded rod 13 to rotate. Under the guidance of the guide rod 15, the threaded rod 13 and the lifting seat 14 are screwed together. Then, the lifting seat 14 drives the pushing device on it to descend to the lowest point and pushes the box. After the pushing is completed, the motor 12 drives the threaded rod 13 to reverse to avoid affecting the normal transportation of the box on the first conveyor belt 2. When the box needs to be transported to the third conveyor belt 5, the pushing device on the base 24 can be directly driven to push the box.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
