Description

Technical Field

[0001] The invention relates to the technical field of electronic label pasting, and in particular to an electronic label pasting strength detection device. Background Art

[0002] Electronic tags, also known as ESL electronic tags, are a technology that replaces traditional paper tags and can automatically identify without contact. It uses radio frequency signals to identify target objects and obtain data, and no human intervention is required when working. Electronic tags have a certain storage capacity and can store relevant information of the identified items, such as product name, model, production date, etc. This information can be read by a reader / writer to achieve rapid identification of the items. In the logistics and transportation industry, by placing electronic tags on transportation tools or goods and installing electronic tag receiving devices on the transportation routes, the status of the goods can be tracked and checked in real time. Logistics companies and customers can retrieve the location and transportation status of goods at any time, improve the service level of logistics companies, and enhance the ability of logistics personnel to respond to emergencies. For this reason, electronic tags play a great role for products.

[0003] Adhesion is a common way to fix electronic tags to products. This method is usually suitable for sticker labels or patch labels. Adhesion is a relatively simple way to fix electronic tags to products. Adhesion generally uses glue, which needs to be applied between the electronic tag machine products to achieve fixation. At present, electronic tags are generally adhered by mechanical automatic adhesion. Mechanical adhesion still has the problem of unreliable adhesion, and unreliable adhesion can easily cause the electronic tags to fall off during product transportation, affecting product identification. Some products have dust on them, and even if the adhered electronic tags are squeezed, the electronic tags cannot be adhered. Based on this, the electronic tags need to be tested to ensure reliable adhesion. Summary of the invention

[0010] Furthermore, the limiting assembly includes a protruding edge integrally arranged on the inner side of the support frame, and a recessed opening cooperating with the protruding edge is opened on the outer side of the outer clamping plate of the upper clamping part to realize the upper and lower sliding of the upper clamping part, and a support spring is also fixed to the inner wall of the upper end of the support frame, and an inner frame is fixed to the lower end of the support spring, and the inner frame is fixed to the upper ends of the two outer clamping plates of the upper clamping part, and the support spring is used to push the upper clamping part downward.

[0011] Furthermore, a conveying isolation component is provided on the conveyor belts of the upper clamping part and the lower clamping part, and the conveying isolation component includes a partition and extended edges on both sides of the partition. A recess is provided on the outer side of the conveyor belt, and one end face of the partition is fixed to the inner wall of the recess. The partition is perpendicular to the conveyor belt, and the extended edges on both sides are respectively fixed on both sides of the partition, and the extended edges on both sides are embedded in the recess. The outward side of the extended edge is flush with the outer side of the conveyor belt to avoid jamming of the product body.

[0012] Furthermore, the transmission isolation component also includes a plurality of inner protruding bars, which are respectively fixed on the inner walls of the upper clamping part and the lower clamping part, and are distributed at equal intervals. The rotating shafts of the upper clamping part and the lower clamping part are provided with mating openings that cooperate with the inner protruding bars during rotation, and the edges of the mating openings are arc edges. When deviations occur between the inner protruding bar and the mating openings, the inner protruding bar and the arc edges of the mating openings are squeezed, so that the inner protruding bar and the mating openings can be re-mated.

[0013] Furthermore, the negative pressure detection part includes an adsorption frame fixed to the middle and outer clamping plates of the upper clamping part, a pipeline is fixed to the outer side of the adsorption frame, and the outer end of the pipeline is connected to a pump body for generating negative pressure.

[0014] Furthermore, the conveyor belt of the upper clamping part is provided with arranged through holes, and a rubber block protruding outward is fixed to the outside of the conveyor belt.

[0018] 1. Place the product body between the upper clamping part and the lower clamping part, and clamp the product body by rotating the partition with the conveyor belt. You only need to put the product body on continuously to complete the transmission detection. Under the downward pressure of the support spring, the conveyor belt of the upper clamping part squeezes the product body to ensure that it is in a stable state, so that the negative pressure detection part can exert force on the electronic tag.

[0019] 2. The extended edges on both sides of the partition are used to keep the partition perpendicular to the conveyor belt. When the partition moves to the outside of the rotating shaft, the extended edges can be separated from the arc-shaped notch to avoid stretching the conveyor belt, avoid deformation of the conveyor belt, and maintain stable transmission.

[0020] 3. The arranged through-holes cooperate with the adsorption ports one by one to realize the upward movement of gas. Since there is only a rubber block between the product body and the conveyor belt, the gap between the rubber blocks is connected to the outside world, realizing the role of air intake and realizing the upward driving force for the electronic tag. The electronic tag that is not firmly adhered will move upward, realizing the role of electronic tag detection.

[0021] 4. The electronic tag being tested is affected by the thickness of the rubber block. If the thickness is small, the gap is small, which increases the flow rate of the gas through the gap. The edge of the electronic tag at the lower end of the through-hole is subjected to a force similar to tearing, which can better detect whether the electronic tag is firmly adhered.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 9, the present invention provides a technical solution: the influence of the reliability of electronic tag adhesion is multifaceted. It is not only related to the durability and readability of the tag, but also directly affects the identification accuracy and management efficiency of the object to which the tag is attached. Reliably adhered electronic tags can ensure that the object always maintains correct identification information in inventory management, logistics tracking and other links, thereby improving management efficiency. Firmly adhered labels reduce the cost of re-identification and management caused by label shedding and damage. Based on this, an electronic tag adhesion strength detection device is proposed, including a support frame 1, an upper clamping part 2 and a lower clamping part 3 located in the support frame 1. The upper clamping part 2 and the lower clamping part 3 are arranged in a coordinated manner up and down to clamp the product body 4. When the product body 4 is clamped, the upper clamping part 2 and the lower clamping part 3 on the upper and lower sides exert an extrusion effect on the product body 4, so that the product body 4 can be stably transmitted along, and the position is prevented from deviating, which is convenient for subsequent negative pressure detection;

[0035] A negative pressure detection unit 7 for negative pressure adsorption is also provided inside the upper clamping unit 2. The output end of the negative pressure detection unit 7 generates negative pressure against the electronic tag of the product body 4, so that the electronic tag has a driving force to separate from the product body 4. Under the action of the negative pressure generated by the negative pressure detection unit 7, the negative pressure detection unit 7 can generate negative pressure on the electronic tag to detect whether the electronic tag is firm. If it is not firm, it will be manually attached later.

[0036] The upper end of the upper clamping part 2 is also provided with a limit assembly 5 for pushing the upper clamping part 2 downward to squeeze the product body 4. The limit assembly 5 is used to make the upper clamping part 2 and the lower clamping part 3 relatively close to each other, so as to clamp the product body 4.

[0037] The upper clamping part 2 includes two outer clamping plates 21, two rotating shafts 22 and conveyor belts 23 driven on the two rotating shafts 22. The two rotating shafts 22 are rotatably installed between the two outer clamping plates 21. The lower clamping part 3 is also arranged in the same manner as the upper clamping part 2. The upper clamping part 2 and the lower clamping part 3 are arranged symmetrically from top to bottom. The conveyor belts 23 on the upper and lower sides are used to clamp and transmit the product body 4, so as to clamp the upper and lower sides of the product body 4 and drive the product body 4 for transmission.

[0038] A driving motor 24 for driving the rotation of one of the rotating shafts 22 is disposed on the outer side thereof. The driving motor 24 is used to drive the conveyor belt 23 to move. In addition, after the product body 4 is clamped, the upper and lower conveyor belts 23 can be transported together.

[0039] The limiting component 5 includes a protruding edge 51 integrally arranged on the inner side of the support frame 1, and a recessed opening 52 cooperating with the protruding edge 51 is provided on the outer side of the outer clamping plate 21 of the upper clamping part 2, which is used to realize the upper and lower sliding of the upper clamping part 2. The upper clamping part 2 can slide vertically up and down, and the gap between the upper clamping part 2 and the lower clamping part 3 can be changed to clamp product bodies 4 of different sizes. A support spring 53 is also fixed to the inner wall of the upper end of the support frame 1, and an inner frame 54 is fixed to the lower end of the support spring 53. The inner frame 54 is fixed to the upper ends of the two outer clamping plates 21 of the upper clamping part 2, and the support spring 53 is used to push the upper clamping part 2 downward. The support spring 53 is used to drive the upper clamping part 2 to move downward, so that the upper clamping part 2 squeezes the product body 4 downward.

[0040] A conveying isolation component 6 is provided on the conveyor belt 23 of the upper clamping part 2 and the lower clamping part 3. The conveying isolation component 6 includes a partition 61 and extended edges 62 on both sides of the partition 61. A recess 63 is opened on the outer side of the conveyor belt 23. One end face of the partition 61 is fixed to the inner wall of the recess 63. The partition 61 is perpendicular to the conveyor belt 23. The extended edges 62 on both sides are respectively fixed on both sides of the partition 61, and the extended edges 62 on both sides are embedded in the recess 63. The outward side of the extended edge 62 is flush with the outer side of the conveyor belt 23 to avoid jamming of the product body 4. It should be noted that the extended edge 62 is used to support the partition 61, but the position of the extended edge 62 is not fixed to the conveyor belt 23. When the conveyor belt 23 moves in an arc state, the extended edge 62 is separated from the recess 63 to avoid pulling the conveyor belt 23, so that the conveyor belt 23 fits the rotating shaft 22 to ensure transmission movement.

[0041] The transmission isolation component 6 also includes a plurality of inner protruding strips 64, which are respectively fixed on the inner walls of the upper clamping part 2 and the lower clamping part 3, and the plurality of inner protruding strips 64 are distributed at the same intervals. The rotating shafts 22 of the upper clamping part 2 and the lower clamping part 3 are provided with matching openings 65 that match with the inner protruding strips 64 during rotation. The edge of the matching opening 65 is an arc edge. When the inner protruding strip 64 and the matching opening 65 deviate from each other, the inner protruding strip 64 and the matching opening 65 are squeezed by the arc edge, so that the inner protruding strip 64 and the matching opening 65 can be re-matched. The inner protruding strip 64 and the matching opening 65 mainly play a positioning role. During the operation of the conveyor belt 23, the conveyor belt 23 will be transmitted along the rotating shaft 22, and the inner protruding strip 64 and the matching opening 65 cooperate. Even if the conveyor belt 23 is partially misaligned, it can be reset along the arc edge of the matching opening 65.

[0042] The negative pressure detection part 7 includes an adsorption frame 73 fixed to the outer clamping plate 21 in the upper clamping part 2. A pipe is fixed to the outside of the adsorption frame 73. The outer end of the pipe is connected to a pump body for generating negative pressure. Through the action of the pump body, the gas is sucked in, and the gas exerts a force on the electronic tag, so that the electronic tag can be detected whether it is firm.

[0043] The conveyor belt 23 of the upper clamping part 2 is provided with arranged through holes 71, and a rubber block 72 protruding outward is fixed on the outer side of the conveyor belt 23. There are multiple rubber blocks 72, which are evenly distributed on the circumference and coaxial with the through hole 71. The lower end of the adsorption frame 73 contacts the conveyor belt 23, and a suction port 74 is provided at the lower end. The adsorption port 74 is connected with the through hole 71 at the lower end. The upper end of the product body 4 is squeezed by the rubber block 72, and the electronic tag is located below the through hole 71. When suction is generated, the gas is transported inward from the gap between the multiple rubber blocks 72. The electronic tag moves and generates a separation force on the electronic tag. After the product body 4 is clamped, the side with the electronic tag is located at the lower end of the through-hole 71, and the multiple rubber blocks 72 are squeezed onto the product body 4. There are connected gaps between the multiple rubber blocks 72. When the through-hole 71 passes through the adsorption port 74, airflow is generated, which moves upward from the gap and generates a force on the electronic tag. The electronic tag that is not firmly attached will move upward to achieve detection. After that, the product body 4 passes through the adsorption port 74, so that the upper end of the next product body 4 is adsorbed and detection is continuously performed.

[0044] The rubber block 72 is provided as a thin layer, so that the gap between the rubber blocks 72 is reduced, the flow rate is increased, and a force is generated on the electronic tag.

[0045] The adsorption port 74 of the adsorption frame 73 is in the shape of a long strip, and the length of the adsorption port 74 is smaller than the distance between two adjacent through-ports 71. When the through-port 71 moves along the adsorption port 74, the through-port 71 and the adsorption port 74 are connected and then separated. During this process, a force can be exerted on the electronic tag. The adsorption port 74 with a long strip setting can increase the force exerted on the electronic tag, and the detection is more accurate.

[0046] The working principle of the present invention is as follows: by driving the motor 24, a conveyor belt 23 is used for transmission, and the product body 4 with the electronic tag attached is placed between the upper clamping part 2 and the lower clamping part 3. Under the action of the partition 61, the upper and lower partitions 61 clamp the product body 4, and the product body 4 moves along the transmission direction. The upper and lower clamping parts 2 and the lower clamping parts 3 both realize the transmission movement. After that, when passing through the negative pressure detection part 7, the negative pressure detection part 7 generates a negative pressure effect on the electronic tag to detect whether the electronic tag is firmly attached. The detection is realized during the transmission process of the product body 4 to maximize the efficiency.

[0047] The product body 4 is transmitted through the conveyor belt 23 as mentioned above, wherein when the product body 4 is placed between the upper clamping part 2 and the lower clamping part 3, the partition 61 rotates along with the conveyor belt 23 to clamp the product body 4, so that the product body 4 can be stably transmitted after being clamped to avoid position deviation. In addition, after the transmission is completed, the product will also be transmitted outward under the push of the partition 61. It is only necessary to continuously put the product body 4 on to complete the transmission detection. In addition, under the action of the support spring 53 squeezing downward, the upper clamping part 2 moves downward, so that the conveyor belt 23 of the upper clamping part 2 squeezes the product body 4 to ensure that it is in a stable state, and the rubber block 72 is supported on the product body 4, which is convenient for the negative pressure detection part 7 to exert force on the electronic tag.

[0048] When the partition 61 moves with the conveyor belt 23, the extension edges 62 on both sides of the partition 61 are used to keep the partition 61 perpendicular to the conveyor belt 23 to ensure that the product body 4 is supported. When the partition 61 moves to the outside of the rotating shaft 22, the extension edges 62 can separate from the arc-shaped recess 63 to avoid stretching the conveyor belt 23 and deformation of the conveyor belt 23, thereby maintaining stable transmission. In addition, under the action of the inner protruding strip 64 and the matching opening 65, the inner protruding strip 64 and the matching opening 65 are matched to drive the conveyor belt 23 to run and transmit the product body 4.

[0049] When the conveyor belt 23 of the upper clamping part 2 is running, the arranged through holes 71 will cooperate with the adsorption holes 74 one by one to realize the upward movement of gas. Since there is only a rubber block 72 between the product body 4 and the conveyor belt 23, the gap between the rubber blocks 72 and the rubber blocks 72 is connected to the outside world, so the air intake is realized, and the upward driving force is realized for the electronic tag. The electronic tag that is not firmly adhered will move upward, and the electronic tag detection is realized, which is convenient for subsequent personnel to manually paste.

[0050] In addition, the electronic tag being tested is affected by the thickness of the rubber block 72. If the thickness is small, the gap is small, which increases the flow rate of the gas through the gap. The edge of the electronic tag located at the lower end of the through hole 71 is subjected to a force similar to tearing, which can better detect whether the electronic tag is firmly adhered.
