Description

Technical Field

[0001] The present invention relates to the technical field of bottle cap processing, and specifically relates to a production method and production equipment for anti-counterfeiting bottle caps and anti-counterfeiting bottle caps. Background Art

[0002] Technologies for anti-counterfeiting through the cooperation between the bottle cap and the bottle body have been applied to a certain extent. Generally, a chip and corresponding interaction components are arranged inside the bottle cap. For example, an RFID (Radio Frequency Identification) tag and a light-emitting component are arranged in cooperation, and communication is carried out through a corresponding verification device, and the feedback of the interaction device is used as anti-counterfeiting verification. At the same time, such bottle caps can also provide entertainment content in specific application scenarios to assist in enhancing the atmosphere of the environment.

[0003] After the traditional bottle cap is separated from the bottle body, it will be damaged and cannot be used again, so as to avoid the bottle cap and the bottle body being used as counterfeit and shoddy products. However, the integration of the chip and interaction components in the traditional bottle cap is poor, and the chip and interaction components arranged inside the bottle cap are easily disassembled and used on counterfeit and shoddy products, so that the counterfeit and shoddy products can pass the anti-counterfeiting verification of the verification device. The main reasons are as follows:

[0004] 1. Insufficient physical protection of the encapsulation process

[0005] For the label encapsulation of existing RFID tag anti-counterfeiting bottle caps and light-emitting anti-counterfeiting bottle caps, technologies such as adhesive pasting, assembly, or heat shrink film wrapping are mostly used, but these processes have obvious defects: the adhesive label is easily affected by the environment, and the viscosity of the adhesive will decrease when the temperature rises, resulting in a decrease in the anti-transfer performance of the anti-counterfeiting label product and can be reused; some designs do not achieve destructive encapsulation of the label, and there is a possibility of recycling and using the RFID chip with data; the structural design does not achieve "destroyed upon opening", and the RFID tag of the traditional bottle cap is not forcibly associated with the opening action, and the complete label or chip can be recovered through non-destructive disassembly.

[0006] 2. Production versatility of the label antenna

[0007] Since the overall production process of the antenna of the existing RFID tag is simple, the production threshold of the antenna is low, making it easy for the recycled chips to be reused by counterfeiters.

[0008] 3. System design loopholes

[0009] Some bottle caps are easily opened with special tools, such as screw caps or snap fasteners, reducing the disassembly difficulty; since the anti-theft structure of the bottle cap and the label anti-counterfeiting technology are implemented separately in production and the generality of their respective production systems is high, it is easy to imitate the bottle cap structure and recycle or forge the label.

[0010] Meanwhile, the traditional process for manufacturing luminous bottle caps is relatively complex and cumbersome, which is not conducive to reducing the production cost of bottle caps. This is mainly reflected in the following aspects:

[0011] 1). Precision molds and complex processing techniques

[0012] High mold development cost: The bottle cap needs to be compatible with luminous components (such as LED light strips), RFID tags, and sealing structures, resulting in complex mold design and long cycle times.

[0013] 2). Material costs and technical limitations

[0014] Dependence on special materials: For example, light guide columns require PC or PMMA materials with high light transmittance, RFID antennas need to be etched after being compounded with conductive layers such as aluminum / copper foils, and the nano-coating of rare earth luminescent materials further increases the cost. Insufficient popularization of low-power chips: To extend the battery life of traditional luminous bottle caps, high-capacity batteries or frequent charging designs are required to meet the power requirements for the normal operation of the bottle cap's lighting and the long-term standby power loss. Such solutions increase the cost of the bottle cap or reduce the convenience of use; however, high-performance low-power chips are relatively expensive, and using such chips will directly increase the production cost; moreover, such a long-life power supply structure with a complex design is not convenient for packaging applications, so it is difficult to obtain a perfect solution.

[0015] It can be seen that there is still room for urgent improvement in the safety and reliability of current bottle caps. Optimization should be carried out to improve their stability and reliability in dealing with cracking, ensure the integration of the internal chips and interactive components, and prevent them from being disassembled and reused in actual applications, thereby reducing counterfeit and shoddy products. Therefore, a more reasonable technical solution needs to be proposed to solve the technical problems existing in the prior art. Summary of the Invention

[0016] To at least overcome one of the above-mentioned defects, the present invention provides a production method, production equipment, and anti-counterfeiting bottle cap for anti-counterfeiting bottle caps. By designing a new production process, the anti-theft structure of the bottle cap, product decoration, and label anti-counterfeiting are integrated. Even if a chip with data is obtained through disassembly, it is not convenient to obtain a replica with similar functions and appearance through existing general processes for secondary use; at the same time, an automated system is used for processing, simplifying some process steps and reducing the processing production cost.

[0017] To achieve the above object, the production method disclosed in the present invention may adopt the following technical solutions:

[0018] A production method for anti-counterfeiting bottle caps, comprising:

[0019] Obtaining a bottle cap blank through injection molding, and forming a groove for installing a chip on the bottle cap blank;

[0020] Perform surface treatment on the bottle cap blank;

[0021] Spray primer on the surface of the bottle cap blank and cure it;

[0022] Apply non-conductive adhesive to dot glue at the groove, and place the chip so that the bottom surface and the surrounding side surfaces of the chip are completely coated by the adhesive;

[0023] Perform coating treatment on the bottle cap blank with the chip placed, and the coating layer is the conductor of the antenna, where the antenna is in direct attachment contact with the chip;

[0024] Carve the coating layer to form the antenna area;

[0025] Spray topcoat on the surface of the bottle cap blank and form a cured layer, thus forming an anti-counterfeiting bottle cap.

[0026] The above-disclosed production method of the anti-counterfeiting bottle cap improves the integrity and integration of the overall structure by directly placing the chip into the groove and bonding it with non-conductive adhesive, and setting the antenna above the chip, thus increasing the difficulty of removing the chip from the bottle cap and preventing the production of counterfeit and shoddy products through recycling based on existing label production equipment; at the same time, through coating treatment and carving treatment, the precision of antenna forming is improved, and automated carving equipment can be used for on-line connection to improve efficiency; in addition to carving the upper surface, the surrounding surfaces of the bottle cap blank can also be carved, which not only ensures that the overall functionality meets the requirements, but also improves the ornamental value of the bottle cap. The traditional process uses the structure of a bottle cap with a self-adhesive label (or shrink sleeve), and the self-adhesive label is composed of glassine paper, adhesive, and surface paper. The process of the present invention directly uses the relevant anti-counterfeiting process of the self-adhesive label to achieve bottle cap decoration, directly saving self-adhesive materials and directly eliminating the labeling link.

[0027] According to the above-disclosed production method of the anti-counterfeiting bottle cap, luminous bottle caps and RFID label anti-counterfeiting bottle caps can be produced and manufactured. During the processing, only the corresponding luminous chip or RFID chip and the corresponding label components need to be selected. In the present invention, for the application of a single chip, the difference between the luminous bottle cap and the RFID anti-counterfeiting bottle cap lies in the difference of the chip itself in terms of product structure.

[0028] Further, the groove is used to place the chip, but the number of chips is not fixed. According to the antenna group design, it can be set to multiple. Here, an optimization is carried out and a feasible option is proposed: the number of the grooves is several, and several luminous chips are correspondingly arranged in each groove. When the above scheme is adopted, the chip can include a luminous chip, an RFID chip, etc., and can meet the requirements for the bottle cap to work under the RFID mode or in the network communication state.

[0029] Further: The preform of the bottle cap guides the internal light to propagate outward. In some solutions, a preform of the bottle cap made of a transparent material can be used to facilitate the propagation of light, for example, it is more convenient for downward and external propagation; in some solutions, an opaque material is used to support the preform of the bottle cap, then a light propagation channel needs to be set, and its structure is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: a light guiding optical path is provided on the preform of the bottle cap, and the light guiding optical path extends towards the upper surface, the peripheral side surfaces or the lower surface of the preform of the bottle cap to guide the light to propagate in the corresponding direction. When the above solution is adopted, a propagation medium can be arranged in the light guiding optical path, or only a reflecting surface can be arranged on the inner wall surface of the light guiding optical path to first guide the internal light to the outside, so as to form a lighting effect outside the preform of the bottle cap, which can be used both as an interactive prompt and as a decoration.

[0030] Further, in order to increase the range of light propagation, more propagation structures can be arranged on the upper surface of the preform of the bottle cap to increase the range of light propagation. Its structure is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: a refraction structure is arranged on the top surface of the preform of the bottle cap, and the refraction structure is used to guide the light to propagate above the preform of the bottle cap. When the above solution is adopted, the refraction structure can adopt some convex structures, such as prisms or pyramids with polygons.

[0031] The above discloses the production method of the anti-counterfeiting bottle cap, which is adjusted and improved based on the existing conventional technology, and the methods of the main improved parts are described. The content related to the conventional technology can be determined without doubt, so it will not be elaborated here.

[0032] The present invention also provides a production device for the anti-counterfeiting bottle cap, which will be described below.

[0033] The production device for the anti-counterfeiting bottle cap includes:

[0034] A circulating conveying track, including several independently driven and mutually connected and cooperating track segments; several functional modules are arranged on the circulating conveying track, at least including a feeding module, a surface treatment module, a dispensing module, a chip insertion module, a track tooling positioning module, a product tooling module, a coating module, a carving module, a spraying module and an oil curing module;

[0035] The coating module includes several coating chambers, and the coating chambers are connected to a vacuum pump group to form a high-vacuum coating environment;

[0036] The track tooling positioning module is used to position the preform of the bottle cap at the required process position and also send the preform of the bottle cap into the coating chamber. The track tooling positioning module includes a feeding component arranged in one-to-one correspondence with the coating chamber, and a positioning pin is connected in cooperation at the feeding component. The positioning pin is used to adjust and control the switching of the feeding component between the fixed state and the non-fixed state.

[0037] The above-mentioned disclosed production equipment is used for automatically processing and producing bottle caps. Among them, the circulating conveyor track is used to convey the bottle cap blanks, drive the bottle cap blanks to travel along the circulating conveyor track, and be processed by the corresponding functional modules. Finally, the formed bottle cap products are obtained. Among them, multiple coating chambers are set in the coating module, which work independently of each other, can perform coating simultaneously, can realize synchronous coating of multiple bottle cap blanks, or perform coating with different materials in different coating chambers. The overall track tooling positioning module can achieve: improving the rotation efficiency of the product, facilitating the guiding of the bottle cap blanks to be coated into the coating chamber, and being able to synchronously seal the coating chamber, and can realize the adjustment of multiple working modes by keeping the feeding component in a fixed state or a non-fixed state, ensuring the smooth and stable progress of the coating work and the accuracy of the coating.

[0038] Furthermore, the circulating conveyor track makes the bottle cap blanks travel along the conveying path, and operations such as attitude adjustment, fixation, local treatment, and component processing and installation are sequentially performed on the path, so as to obtain the finished bottle caps. The structure of the circulating conveyor track is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: there are four track sections forming a cross-conveying section, and a cross-conveying control cabinet is set at the cross-conveying section. The cross-conveying control cabinet is used to control the staggered connection and cooperation of the corresponding track sections. When the above solution is adopted, at the cross-conveying section, the conveying paths of the circulating conveyor track form a cross, and the cross-conveying control cabinet is located at the cross of the conveying paths. The cross-conveying control cabinet is used to intermittently communicate and cooperate with one of the track sections, so that this track section can maintain normal connected conveying. The purpose of the four tracks forming a cross installation is to make the common production operation workstations be in relatively close positions, and as much as possible to facilitate the debugging production operators to reduce position movement. Simply from the layout of the production equipment unit, a ring conveyor line can also be adopted.

[0039] In the present invention, multiple track sections are all driven by independent driving components to improve the conveying capacity of the track, and the conveying track can operate independently. Cooperating with the track tooling positioning module, it can conveniently realize the flexible positioning stop and conveying of the product tooling module without changing the operating state of the track conveying, meet the processing operations of the functional modules on this track section and do not affect the work of other track sections of the entire processing production.

[0040] Further, in the present invention, the coating chamber is used for coating the blank caps, including coating the four side surfaces and the top surface, and its structure is not uniquely defined. Here, one feasible option is optimized and proposed: the coating chamber includes a plurality of cathode chambers, and each cathode chamber includes a plurality of chamber units for providing coating materials. The chamber units coat the blank caps through a hollow cathode sputtering coating structure. When the above solution is adopted, the coating operations of multiple blank caps can be realized synchronously, and coatings can also be applied using multiple different coating materials.

[0041] In some solutions, in order to coat the blank caps in multiple directions, a top coating cathode and a side coating cathode are arranged in the coating chamber to coat the top and side surfaces of the blank caps with different coating thicknesses.

[0042] In some solutions, a coating mask is also provided to form a coating shielding structure on the surface of the blank caps to achieve local coating and obtain a coating structure with a corresponding shape.

[0043] Further, the feeding assembly is used to lift the blank caps. When the blank caps enter the coating chamber or the printing and decoration station, it can also be used to adjust the circumferential position of the caps, so as to realize various coating or printing and decoration solutions. The structure of the feeding assembly can be constructed in various forms and is not uniquely defined. Here, one feasible option is optimized and proposed: the feeding assembly includes a positioning connecting piece, and positioning holes for circumferential positioning and for limiting the feeding assembly to maintain a fixed state are formed on the positioning connecting piece. A circumferential groove for maintaining the feeding assembly in a non-fixed state is also provided. When the positioning pin is inserted into the positioning hole in cooperation, the feeding assembly maintains a fixed state. When the positioning pin is engaged with the circumferential groove, the feeding assembly maintains a non-fixed state.

[0044] Furthermore, by the positioning pin cooperating with the positioning hole or the circumferential groove of the feeding assembly, the feeding assembly can be maintained in a fixed or released state. Specifically, the cooperation between the positioning pin and the feeding assembly can be realized in various ways, and its structure is not uniquely defined. Here, one feasible option is optimized and proposed: the positioning pin is connected to a switch member. When the switch member performs an action, it drives the positioning pin to act and cooperate with the positioning hole, or drives the positioning pin to cooperate with the circumferential groove. When the above solution is adopted, with the switch member as the control and adjustment, the switching of the cooperation position of the positioning pin can be realized, so as to maintain the fixed state or the non-fixed state of the feeding assembly.

[0045] The above content discloses the production equipment and describes the specific improved parts and structures.

[0046] The present invention also discloses an anti-counterfeiting cap made by the production method described above or processed by the production equipment described above.

[0047] Compared with the prior art, some beneficial effects of the disclosed technical solution of the present invention include:

[0048] The production method disclosed by the present invention proposes a brand-new production method for anti-counterfeiting bottle caps, simplifies the corresponding processing technology, and improves the degree of automation. In the aspect of bottle cap anti-counterfeiting, the chip anti-counterfeiting application technology is integrated into the production process of bottle cap products, realizing the single-structure overall integration of the bottle cap product structure, decoration, and anti-counterfeiting application, which can further increase the comprehensive difficulty of secondary utilization of the chips after disassembly. In particular, the application of the solution can change the current situation where bottle cap products are basically anti-counterfeited by combining anti-theft structures with anti-counterfeiting labels, and can effectively prevent parts of the products from being individually cracked, replicated, recycled, and recombined for forgery. Therefore, the anti-counterfeiting reliability is improved as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The following further explains this embodiment in conjunction with the accompanying drawings and specific embodiments.

[0065] Aiming at the deficiencies existing in the processing and production of existing luminous bottle caps and RFID tag anti-counterfeiting bottle caps, the following embodiments are optimized to overcome the deficiencies existing in the prior art.

[0066] Embodiment 1

[0067] As Figure 12 shown, this embodiment proposes a production method for anti-counterfeiting bottle caps, including:

[0068] S01. Obtain a bottle cap blank by injection molding, and form a groove for installing a chip on the bottle cap blank;

[0069] S02. Perform surface treatment on the bottle cap blank;

[0070] S03. Spray and cure a primer on the surface of the bottle cap blank;

[0071] S04. Apply non-conductive adhesive to dispense glue at the groove, and place the chip. Ensure that the bottom surface and the surrounding side surfaces of the chip are coated with the adhesive, and the upper surface of the chip is flush with the surface of the bottle cap blank.

[0072] S05. Perform a coating process on the bottle cap blank with the chip placed inside. The coating layer serves as the conductor of the antenna, where the antenna is in direct attachment contact with the chip.

[0073] S06. Engrave the coating layer to form the antenna area.

[0074] S07. Spray surface varnish on the surface of the bottle cap blank to form a cured layer, thereby forming a luminous bottle cap.

[0075] The production method of the anti-counterfeiting bottle cap disclosed in this embodiment improves the integrity and integration of the overall structure by directly placing the chip into the groove and bonding it with non-conductive adhesive, and setting the antenna above the chip. This makes it difficult to remove the chip from the bottle cap without damage by simple methods, and counterfeit and shoddy products cannot be made by simple recycling methods. At the same time, through the coating process and engraving process, the precision of antenna forming is improved, and automated engraving equipment can be used, thus reducing manual processing operations and improving efficiency. In addition to engraving the upper surface, the surrounding surfaces of the bottle cap blank can also be engraved, which not only ensures that the overall functionality meets the requirements but also improves the ornamental value of the bottle cap.

[0076] According to the production method of the anti-counterfeiting bottle cap disclosed above, luminous bottle caps and RFID tag anti-counterfeiting bottle caps can be produced and manufactured. During the processing, only a luminous chip or an RFID chip and corresponding tag components need to be selected accordingly. In this embodiment, for the application of a single chip, the difference between the luminous bottle cap and the RFID anti-counterfeiting bottle cap lies in the difference of the chip itself in terms of product structure.

[0077] Preferably, in this embodiment, there are multiple schemes for the injection molding of the bottle cap blank, and the following settings can be considered comprehensively:

[0078] A) When designing the product, consider the luminous effect of the luminous chip and determine the position. Preferably, it is the center position at the top of the bottle cap. At the position where the luminous chip is to be placed, a groove is preset in the bottle cap structure design to facilitate the dispensing of glue for binding the luminous chip and ensure that the surface of the luminous chip is at the same height as the top surface of the bottle cap after the luminous chip is placed.

[0079] B) If it is compatible with downward illumination, preferably use transparent material.

[0080] C) If only upward illumination is considered, a light guide path needs to be formed during the injection molding of the bottle cap or during subsequent processing (in the area outside the chip groove and communicating with the chip groove), or a structure for increasing interface reflection needs to be designed (a bevel structure is added inside the top of the bottle cap to increase light refraction and reduce direct light escape), so as to increase the upward light output. For the application of the RFID anti-counterfeiting method, such a design is not required (the surface of the bottle cap is flat).

[0081] D) For the upward light emission application of opaque materials, it is necessary to cooperate with the designed antenna shape, engrave the corresponding antenna shape lines with appropriate line widths on the mold, form grooves during the injection molding of the bottle cap, fill the grooves after spraying the primer, and utilize the transparent characteristics of the sprayed primer to facilitate the propagation of light.

[0082] Preferably, in this embodiment, during the surface treatment of the bottle cap blank in step S02, it also includes spraying and curing the primer on the bottle cap surface, so as to decorate the bottle cap blank and prepare for subsequent anti-counterfeiting printing.

[0083] Preferably, in this embodiment, during the coating treatment in step S05, it includes forming a highly reflective coating layer to help the light reflect and propagate, which can improve the effect of downward or upward propagation.

[0084] The groove is used to place the chip, but the number of chips is not fixed and can be set to multiple. This embodiment is optimized and one feasible option is adopted: the number of the grooves is several, and several light-emitting chips are correspondingly arranged in each groove. When the above scheme is adopted, the chip can include a light-emitting chip; when an RFID chip is set, the number of RFID chips is one, which can meet the controlled operation of the bottle cap in the RFID mode or the operation in the network communication state.

[0085] In this embodiment, the difference from the existing RFID tag production process: in the existing process, the chip is bound to the antenna, that is, the antenna exists first and then the chip is bound; while this process can be summarized as - binding the antenna on the chip, that is: first, implant and bind the chip with glue, then coat the bottle cap and the chip together as a whole, and then form the antenna / power line on the top of the bottle cap. When operating and processing like this, the chip and the bottle cap form a whole. At the same time, the chip is directly attached to the antenna in contact, avoiding the situation that the conductive glue in the existing process has poor contact with the chip and the antenna.

[0086] The cap blank guides the internal light to propagate outward. In some solutions, a cap blank made of a transparent material can be used to facilitate the outward propagation. In some solutions, an opaque material is used to support the cap blank, and a light propagation channel needs to be set up. Its structure is not uniquely defined. In this embodiment, it is optimized and one of the feasible options is adopted: a light guiding optical path is provided on the cap blank, and the light guiding optical path extends towards the upper surface, the peripheral side surfaces or the lower surface of the cap blank to guide the light to propagate in the corresponding direction. When the above solution is adopted, a propagation medium can be set in the light guiding optical path, or only a reflecting surface can be set on the inner wall surface of the light guiding optical path to first guide the internal light to the outside, so as to form a lighting effect outside the cap blank, which can be used as both an interactive prompt and a decoration.

[0087] To increase the range of light propagation, more propagation structures can be provided on the upper surface of the cap blank to increase the range of light propagation. Its structure is not uniquely defined. In this embodiment, it is optimized and one of the feasible options is adopted: a refraction structure is provided on the top surface of the cap blank, and the refraction structure is used to guide the light to propagate above the cap blank. When the above solution is adopted, the refraction structure can adopt some convex structures, such as a prism or a pyramid with a polygonal shape.

[0088] The above content discloses the production method of the anti-counterfeiting cap, which is adjusted and improved based on the existing conventional technology, and the methods of the main improved parts are described. The content related to the conventional technology can be determined without doubt, and will not be elaborated in this embodiment.

[0089] Embodiment 2

[0090] As Figures 1 to 11 shown, this embodiment provides a production device for the anti-counterfeiting cap, which will be described below.

[0091] The anti-counterfeiting cap production device includes:

[0092] As Figure 2 、 Figure 3 shown, the circulating conveyor track 1 includes several independently driven and mutually connected and cooperating track segments; several functional modules are provided on the circulating conveyor track 1, including at least a feeding module, a surface treatment module, a dispensing module, a chip insertion module, a track tooling positioning module, a product tooling module, a coating module, a carving module, a spraying module and an oil curing module;

[0093] As Figures 4 to 8 shown, the coating module includes several coating chambers 402, and the coating chambers 402 are connected to a vacuum pump group and are used to form a high-vacuum coating environment;

[0094] As Figure 9 、 Figure 10 、 Figure 11As shown, the orbital tooling positioning module is used to position the preform of the bottle cap at the required process position and also feed the preform of the bottle cap into the coating chamber 402. The orbital tooling positioning module includes a loading component arranged in one-to-one correspondence with the coating chamber 402, and a positioning pin 20 is connected in cooperation at the loading component. The positioning pin 20 is used to adjust and control the switching of the loading component between the fixed state and the non-fixed state.

[0095] The production equipment disclosed in this embodiment is used to automatically process and produce bottle caps. Among them, the circulating conveying track 1 is used to convey the preform of the bottle cap, drive the preform of the bottle cap to travel along the circulating conveying track 1, and be processed by the corresponding functional modules, and finally obtain the formed bottle cap product. Among them, a plurality of coating chambers 402 are arranged in the coating module, which work independently of each other, can perform coating simultaneously, can realize synchronous coating of a plurality of preforms of the bottle cap, or perform coating of different materials in different coating chambers 402. The orbital tooling positioning module as a whole can achieve: improving the rotation efficiency of the product, facilitating the guiding of the preform of the bottle cap to be coated into the coating chamber, and being able to synchronously seal the coating chamber 402, and can realize the adjustment of various working modes by maintaining the fixed state or non-fixed state of the loading component, ensuring the smooth and stable progress of the coating work and ensuring the accuracy of the coating.

[0096] The circulating conveying track 1 makes the preform of the bottle cap travel along the conveying path, and operations such as attitude adjustment, fixation, local treatment, and component processing and installation are sequentially performed on the path, so as to obtain the finished bottle cap. The structure of the circulating conveying track 1 is not uniquely limited. In this embodiment, an optimization is carried out and one of the feasible options is adopted: there are four track sections forming a cross-conveying section, and a cross-conveying control cabinet 2 is arranged at the cross-conveying section. The cross-conveying control cabinet 2 is used to control the staggered connection and cooperation of the corresponding track sections. When the above scheme is adopted, at the cross-conveying section, the conveying path of the circulating conveying track 1 forms a cross, and the cross-conveying control cabinet 2 is located at the cross of the conveying path. The cross-conveying control cabinet 2 is used to intermittently communicate and cooperate with one of the track sections, so that this track section can maintain normal connected conveying.

[0097] In this embodiment, multiple track sections are all driven by independent driving components to improve the conveying capacity of the track, and the conveying track can operate independently. Cooperating with the orbital tooling positioning module, it can conveniently realize the flexible positioning stop and conveying of the product tooling module without changing the operating state of the track conveying, meet the processing operations of the functional modules on this track section and do not affect the work of other track sections of the entire processing production.

[0098] In this embodiment, the coating chamber 402 is used to coat the blank caps, including coating the peripheral (or circumferential) side and the top surface. Its structure is not uniquely defined. In this embodiment, an optimization is carried out and one of the feasible options is adopted: the coating chamber 402 includes a plurality of cathode chambers, and each cathode chamber includes a plurality of chamber units for providing coating materials. The chamber units coat the blank caps through a hollow cathode sputtering coating structure. When the above scheme is adopted, the coating operations of multiple blank caps can be realized synchronously, and coating with a variety of different coating materials can also be realized.

[0099] Preferably, in this embodiment, the coating chamber 402 is connected to the high-vacuum chamber 12, and the high-vacuum state in the coating chamber 402 is synchronously realized through the high-vacuum state formed by the high-vacuum chamber 12. The high-vacuum chamber 12 is then assisted by connecting a plurality of vacuum pumps to extract the gas in the high-vacuum chamber 12 and maintain the high-vacuum state. The vacuum pumps include a magnetic levitation molecular vacuum pump 13, a roots pump 15, a mechanical pump 14, etc.

[0100] In this embodiment, the magnetic levitation molecular vacuum pump 13 is used to increase the gas pumping speed and improve the vacuum degree of the high-vacuum chamber 12. In traditional coating equipment, the coating chamber is the highest vacuum area of the system. In this embodiment, an adjustment is made. In order to improve production efficiency, a buffer vacuum chamber is set as the high-vacuum chamber to facilitate the rapid attainment of the working vacuum in the coating working area.

[0101] Preferably, regarding the specific structure at the coating chamber 402, it includes a coating body 4 forming the coating chamber 402. A plurality of coating chambers 402 are formed inside the coating body 4.

[0102] In some schemes, in order to coat the blank caps in multiple directions, a top coating cathode 9 and a side coating cathode 10 are provided in the coating chamber 402 for coating the top and side of the blank caps with different coating thicknesses. Specifically, a top coating cathode 9 and a side coating cathode 10 are provided in each coating chamber 402. The top coating cathode 9 and the side coating cathode 10 are both supported by the bottom insulating material layer 8, so as to be insulated and separated from the coating body 4. A cap inlet is provided at the lower part of the coating body 4 to facilitate the caps to enter from the cap inlet.

[0103] In some schemes, a coating mask 11 (local coating shielding cover) is also provided to form a local coating on the surface of the blank caps to obtain a coating structure with a corresponding shape.

[0104] Preferably, the structure of the coating mask 11 can be set as a cylinder to surround the preform of the bottle cap, so as to realize the coating operation on the preform of the bottle cap.

[0105] In some solutions, by setting magnetic elements in the feeding component to form a certain magnetic field distribution, and using the guidance of the electric field, local coating of the bottle cap itself can be realized, so as to meet special coating requirements, such as local coating operations for improving the decorative effect. In this solution, the characteristics of the electric field and the magnetic field can also be used to change the coating area and even shield some areas during coating.

[0106] The feeding component is used to support the preform of the bottle cap. When the preform of the bottle cap enters the coating chamber 402, it can also be used to adjust the circumferential position of the bottle cap, so as to realize various coating solutions. The structure of the feeding component can be constructed in various forms, and its structure is not uniquely limited. In this embodiment, it is optimized and one feasible option is adopted: the feeding component includes a positioning connecting piece 18. A positioning hole 1801 for circumferential positioning and limiting the feeding component to maintain a fixed state is formed on the positioning connecting piece 18, and an annular groove 1802 for maintaining the feeding component in a non-fixed state is also provided. When the positioning pin 20 is inserted into the positioning hole 1801 in cooperation, the feeding component maintains a fixed state. When the positioning pin 20 is engaged with the annular groove 1802, the feeding component maintains a non-fixed state.

[0107] Preferably, the feeding component adopted in this embodiment includes a tray seat 23. Support components are correspondingly arranged on the tray seat 23 corresponding to the coating chamber 402. The support component includes a bearing component 16. The bearing component 16 is connected to a vertical rotating shaft 22. A positioning connecting piece 18 is rotatably sleeved on the rotating shaft 22. A sealing inertia plate 17 is also arranged on the positioning connecting piece 18. An upper feeding head 19 for jacking up the preform of the bottle cap is coaxially connected to the positioning connecting piece 18.

[0108] The tray seat 23 includes a bottom plate 2301 and a mounting plate 2302. A plurality of positioning pins 20 and a plurality of guide pins are correspondingly arranged between the bottom plate 2301 and the mounting plate 2302.

[0109] The bearing component 16 includes a bearing seat 1601 arranged on the mounting plate 2302, and also includes a bearing 1602 arranged in the bearing seat 1601. The rotating shaft 22 rotates in cooperation with the bearing 1602.

[0110] By positioning the pin 20 to cooperate with the positioning hole 1801 or the circumferential groove 1802 of the feeding component, the feeding component can be fixed or unfixed. Specifically, the cooperation between the positioning pin 20 and the feeding component can be achieved in various ways, and its structure is not uniquely limited. In this embodiment, optimization is carried out and one feasible option is adopted: the positioning pin 20 is connected to the switch member 21. When the switch member 21 performs an action, it drives the positioning pin 20 to cooperate with the positioning hole 1801 or drives the positioning pin 20 to cooperate with the circumferential groove 1802. When the above solution is adopted, with the switch member 21 as the control adjustment, the switching of the cooperation position of the positioning pin 20 can be realized, so as to maintain the fixed state or the non-fixed state of the feeding component.

[0111] Preferably, the number of the positioning connectors 18 in this embodiment is two. The positioning pin 20 is arranged between the positioning connectors 18. The positioning pin 20 is an elastic pin, which forms two elastic pin heads and is elastically clamped into the positioning hole 1801 or the circumferential groove 1802. The switch member 21 is arranged on the mounting plate 2302 and is connected in cooperation with the positioning pin 20. The switch member 21 is a pressing type elastic member, which drives the positioning pin 20 to rise or fall in the vertical direction, so as to switch the cooperation with the positioning hole 1801 and the circumferential groove 1802.

[0116] In some embodiments, the anti-counterfeiting bottle cap is an RFID bottle cap, a single RFID chip is provided, and a closed-loop circuit and an anti-counterfeiting decorative structure are also provided. The anti-counterfeiting device structure includes device structures arranged at positions such as the top and side of the bottle cap, including hollowing, patterns, etc. The corresponding closed-loop circuit is used in cooperation with the RFID chip, and various circuit structures in the prior art can be flexibly adopted.
