Description

Technical Field

[0001] This utility model relates to the field of intelligent equipment technology, and in particular to an unattended device for scanning and retrieving items, specifically an automatic dispensing device for scanning and retrieving items. Background Technology

[0002] As we all know, with the support of the Internet of Things, intelligentization, unmanned operation, and automation have developed rapidly in recent years. Automatic ticket vending machines, automatic beverage vending machines, automatic fitness equipment dispensing machines, and so on are ubiquitous in people's lives.

[0003] Although unmanned delivery devices have been systematically implemented in various aspects of people's lives, some items are still limited by environment and location and have not been widely adopted.

[0004] In recent years, the forms of advertising distribution have gradually changed, shifting from traditional fixed posters and screens to small items that can be distributed at any time, such as fans, tissues, matches, lighters, etc. The relevant advertisements are printed on their outer packaging or on the items themselves. However, after market research and investigation, the distribution mode of such small items is still mainly based on human distribution. This is mainly because these small items have a certain degree of practicality, and it is necessary to avoid recipients taking too many or all of them at once, which would affect the advertising effect.

[0005] The survey also found that items such as lighters and matches are more widely accepted than items such as fans and tissues. However, these items still pose a certain risk and should not be given to children to prevent fire hazards caused by improper use.

[0006] The survey revealed that the demand for lighters and matches is mostly concentrated in places such as chess and card rooms, teahouses, billiard halls, and internet cafes, which are also open to adults. Currently, these products are generally provided for a fee in these places, usually for 1-2 yuan, or they are not sold at all. Those who need them need to go to the nearest convenience store to buy them, which causes a lot of inconvenience to customers. Summary of the Invention

[0007] The technical problem this utility model aims to solve is to address the shortcomings of existing technologies by providing an automatic dispensing device for lighters or matches, primarily designed for automatic dispensing. The device itself uses an iron casing, which effectively prevents external damage and potential fires caused by ignition sources, while also providing fire protection to prevent spontaneous combustion. The device uses a barcode scanning mechanism to drive an internal motor to rotate a dispensing rod. Dispensing tabs on the rod remove the lighter or matchbox from its designated slot, causing it to fall into a hopper. Each scan drives the motor to rotate once, dispensing one lighter or matchbox at a time. The device has a simple structure and offers good reliability and stability.

[0008] The technical solution of this utility model is to provide an automatic barcode scanning and dispensing device, including a box body, which is composed of two parts: an upper cover and a rear compartment. The rear compartment is provided with a barcode slot for stacking items. The outlet of the barcode slot is provided with a limiting baffle to restrict the movement of items along the barcode slot. The outlet of the barcode slot is provided with a push rod. One end of the push rod is connected to the main shaft of a servo motor, and the other end of the push rod is provided with a sensor detection plate. A push plate is provided on the push rod at a position corresponding to the outlet of the barcode slot. The limiting baffle is provided with a channel that allows the push plate to pass through. The size of the limiting baffle is smaller than the size of the outlet of the barcode slot. A drop port is provided between the limiting baffle and the barcode slot.

[0009] As a further optimization, the sensor detection disk is equipped with detection claws, and the number of detection claws is the same as the number of material feeding plates.

[0010] As a further optimization, the feeding rod is fixed to the rear chamber body by a bracket and bearing.

[0011] As a further optimization, the feed inlet of the feed slot is equipped with an upper pressure plate, and an angle sensor for detecting the rotation angle of the feed lever is also provided on the rear compartment body near the sensor detection plate.

[0012] As a further optimization, a material drop chamber is formed between the bottom of the material feeder and the rear chamber. The upper cover is provided with a material retrieval port at the position of the material drop chamber. The material retrieval port is also provided with a baffle plate to prevent the internal structure from being seen from the material retrieval port.

[0013] As a further optimization, the code slot is a C-shaped profile, the bottom of the code slot is connected to the rear compartment body through a support frame, the code slot is a multi-group structure arranged in parallel, and the number of code slots is the same as the number of material feeding pieces.

[0014] As a further optimization, the number of the code slots includes three, the number of the material picks is three, and the angle between two adjacent material picks is 120°.

[0015] As a further optimization, the upper cover and the rear compartment are connected by one or more of the following: hinges, latches, pins, and latches.

[0016] As a further optimization, the rear compartment is provided with mounting holes for connection to the wall, and the upper cover and the rear compartment are also provided with locks.

[0017] As a further optimization, the surface of the upper cover is also provided with a QR code scanning window, and the rear compartment is also provided with a signal antenna mounting hole. The angle sensor, servo motor, and signal antenna are all electrically connected to a controller, which is located inside the rear compartment. The rear compartment is also provided with a power supply that provides power to the controller, angle sensor, servo motor, and signal antenna.

[0018] The beneficial effects of this technical solution are as follows: Through research, lighters or matches, which are widely accepted by the public, are used as advertising carriers. Advertisements are printed on the lighters or matchboxes. Then, a device is activated by scanning a QR code with a mobile phone, which peels off the QR code from the lighter or matchbox. When the user picks up the lighter or matchbox, they see the information, thus completing the advertising. The device has a simple structure, good stability, and is constructed entirely of steel to avoid potential hazards. Attached Figure Description

[0024] For ease of explanation, the following is in conjunction with the appendix. Figure 1-5 This paper provides a detailed description of the utility model of an automatic QR code scanning and dispensing device.

[0025] An automatic dispensing device for scanning codes to dispense items is mainly used for dispensing lighters 22, matches, and other special advertising media in special locations. It includes a box body 1, which consists of two parts: an upper cover 1.1 and a rear compartment 1.2. The upper cover 1.1 and the rear compartment 1.2 are connected on one side by one or more of a hinge, pin, or latch. This technical solution uses a practical and simple hinge. Since both the upper cover and the rear compartment are made of iron, they can be directly welded using the same iron hinges, making them durable and reliable.

[0026] The rear compartment 1.2 is equipped with a stacking slot 2 for stacking items. The outlet of the stacking slot 2 is equipped with a limiting baffle 3 to restrict the movement of items along the direction of the stacking slot 2. The equipment is generally placed vertically, and the items can be automatically moved in the stacking slot by the weight of the lighter 22 or matchbox, which can eliminate the need for a forced displacement mechanism. To prevent the lighter or matchbox from falling directly, the limiting baffle 3 is set. The size of the limiting baffle 3 is smaller than the size of the outlet of the stacking slot 2. A discharge port 9 is provided between the limiting baffle 3 and the stacking slot 2. The outlet of the stacking slot 2 is also used for discharging lighters or matchboxes, so the size of the limiting baffle 3 should not be too large. As shown in the figure, the limiting baffle 3 only occupies about 1 / 3 of the entire outlet, which not only prevents the lighter or matchbox from falling freely, but also allows the lighter or matchbox to slide out of the discharge port 9 under the action of external force.

[0027] The groove 2 has a feeding rod 4 at its outlet, which is fixed to the rear compartment 1.2 by a bracket and bearing. One end of the feeding rod 4 is connected to the main shaft of the servo motor 5. A feeding piece 7 is provided on the feeding rod 4 at the position corresponding to the outlet of the groove 2. The limiting baffle 3 has a channel 8 that allows the feeding piece 7 to pass through. The rotation of the servo motor 5 drives the feeding piece 7 to rotate. The feeding piece 7 is the external force acting on the lighter or matchbox. Since the feeding piece 7 is connected to the feeding rod 4, as the feeding rod 4 rotates, the feeding piece 7 provides external force to the lighter or matchbox. This requires the feeding piece to contact the lighter or matchbox and interfere with it. To achieve this effect, the limiting baffle 3 has a two-section structure, located on both sides of the groove, with a channel 8 reserved in the middle for the feeding piece 7 to pass through.

[0028] The other end of the feeding rod 4 is equipped with a sensor detection disk 6. An angle sensor 11 for detecting the rotation angle of the feeding rod 4 is also provided on the rear compartment 1.2 adjacent to the sensor detection disk 6. The sensor detection disk 6 is equipped with detection claws 6.1, and the number of detection claws 6.1 is the same as the number of feeding pieces 7. As shown in the figure, the code slots 2 are multiple sets arranged in parallel, and the number of code slots 2 is the same as the number of feeding pieces 7. There are three code slots 2 and three feeding pieces 7. The angle between two adjacent feeding pieces 7 is 120°. With one feeding piece 7, the feeding rod 4 rotates once to obtain one lighter. And only one code slot 2 can be set. Under the same size shell, the number of lighters or matchboxes stored in the device is small. After research and design studies, taking into account the device's operating time and product size, it was finally set to three sets of code slots 2, which also correspond to three feeding pieces 7. The servo motor 5 can realize the drop of three lighters or matchboxes with one rotation. Meanwhile, there are also three detection claws 6.1 on the sensor detection disk 6 used in conjunction with the angle sensor 11. It is common knowledge in the art to use the angle sensor 11 and the detection claws 6.1 on the sensor detection disk 6 to provide the servo motor 5 with the rotation angle signal, and its working principle will not be described in detail here.

[0029] The feed inlet of the coding slot 2 is equipped with an upper pressure plate 10. The upper pressure plate 10 has a certain weight and provides a downward pressure to further promote the smooth sliding of the lighter or matchbox in the coding slot 2 and prevent it from getting stuck and affecting the dispensing.

[0030] A material drop chamber 12 is formed between the bottom of the push rod 4 and the rear compartment 1.2. After the scanning drive servo motor 5 rotates, the lighter 22 or matchbox is pushed by the push plate 7 and slides out from the material drop port 9. Without any preparation, it is impossible for a person to directly grab the freely falling lighter 22. Therefore, the material drop chamber 12 is formed by utilizing the space at the bottom of the rear compartment 1.2. After the lighter 22 slides out of the material drop port 9, it will fall into the material drop chamber 12. The upper cover 1.1 is provided with a retrieval port 13 at the position of the material drop chamber 12. People can retrieve the lighter 22 that has fallen into the material drop chamber 12 through the retrieval port 13.

[0031] The retrieval port 13 is also provided with a baffle plate 14 to prevent the internal structure from being seen from the retrieval port 13; the material dropping component described in this technical solution has a simple structure. The baffle plate 14 is not only to prevent the view of the inside, but more importantly, to prevent people from picking up the lighter with their fingers through the retrieval port 13 or catching the lighter before it falls, because the internal material feeding rod 4 and material feeding plate 7 are rotating, which may pose a safety hazard such as squeezing fingers.

[0032] The groove 2 is a C-shaped profile. The bottom of the groove 2 is connected to the rear compartment 1.2 through the support frame 23. The C-shaped profile has a simple structure and high strength. Under normal circumstances, the bottom of the groove 2 is directly connected to the rear compartment 1.2 through the support frame 23 by welding.

[0033] The rear compartment 1.2 is provided with mounting holes 15 for connection to the wall, for use with expansion bolts on the wall. The upper cover 1.1 and the rear compartment 1.2 are also provided with locks 16 to prevent the lighter 22 or matches inside from being taken away by others at once, thus losing the so-called advertising effect.

[0034] The upper cover 1.1 has a QR code scanning window 17, and the rear compartment 1.2 has a signal antenna mounting hole 18. The angle sensor 11, servo motor 5, and signal antenna 19 are all electrically connected to a controller 20, which is located inside the rear compartment 1.2. The rear compartment 1.2 also has a power supply 21 that provides power to the controller 20, angle sensor 11, servo motor 5, and signal antenna 19. The design uses a built-in power supply, which is not limited by the installation location. Of course, an external power supply can also be used, which requires continuous power. When people scan the QR code on the device with their mobile phones, the backend sends a signal to the device. After the device receives the signal through the signal antenna 19, the controller 20 sends a signal to drive the servo motor 5 to rotate. During the rotation, the material pick 7 peels the lighter 22 off the code slot 2. At the same time, the angle sensor 11 detects the detection claw 6.1 and sends a signal back to the controller 20. The controller 20 then sends a signal to stop the servo motor 5 from rotating, completing one cycle. The controller 20 here uses a microcontroller.

[0035] In the above embodiments, the preferred implementation of the present utility model has been described. Obviously, many changes can still be made under the inventive concept of the present utility model. Here, it should be stated that any changes made under the inventive concept of the present utility model will fall within the protection scope of the present utility model.
