Abstract
Description
Technical Field
[0001] This utility model relates to the field of pad printing cleaning consumable replacement technology, specifically to a quick-change device for tape consumables and pad printing equipment. Background Technology
[0002] In the production process of contact lenses, the pad printing process uses a feeder mechanism to install the cleaning tape type consumables. The waste shaft and the roller shaft are not integrated. When replacing them, the waste material and the excess material on the feeder need to be removed from the shaft core separately, which is also cumbersome.
[0003] Meanwhile, there are generally two approaches when changing auxiliary materials: shutting down the main production line or adding a dual feeder. Shutting down the main production line will result in prolonged downtime, causing production waste. Adding a dual feeder, while increasing equipment uptime, will increase production costs.

[0005] In one aspect, the present invention provides a quick-change device for adhesive tape consumables, comprising a quick-change base and a pre-installed cartridge body. The pre-installed cartridge body and the quick-change base are connected in a first axial direction by at least one set of snap-fit components. At least a portion of the snap-fit components is disposed on the quick-change base, and the remaining portion is disposed on the pre-installed cartridge body. The at least portion and the remaining portion snap-fit each other, thereby fixing the pre-installed cartridge body relative to the quick-change base in the first axial direction. A locking component is also provided between the pre-installed cartridge body and the quick-change base to prevent the pre-installed cartridge body from displacing in a second axial direction perpendicular to the first axis.
[0006] In some embodiments of this application, the snap-fit assembly includes a snap block and a fixing member. The fixing member has a snap groove that at least partially mates with the snap block. One of the snap block and the fixing member is disposed on the support plate of the quick-change base, and the other is disposed on the fixing plate of the pre-assembled cassette cartridge.
[0007] In some embodiments of this application, the support plate or fixing plate is provided with a sliding groove arranged along the second axis direction that communicates with the slot.
[0008] In some embodiments of this application, the card block has a T-shaped structure, and the card slot has a T-shaped structure.
[0009] In some embodiments of this application, the snap-fit components are in three groups and arranged in a triangular pattern.
[0010] In some embodiments of this application, the locking assembly includes a locking limit rod and a locking groove / hole, one of which is disposed on the support plate and the other is disposed on the fixing plate, and at least a portion of the locking limit rod can extend into the locking groove / hole through a first driver.
[0011] In some embodiments of this application, the fastener is a C-shaped structure.
[0012] In some embodiments of this application, a second driver is provided on the quick-change base.

[0030] Combination Figure 1-6 As shown, this embodiment provides a quick-change device for tape consumables, including a quick-change base and a pre-installed cassette cartridge. The pre-installed cassette cartridge and the quick-change base are connected in the first axial direction by at least one set of snap-fit components. At least a portion of the snap-fit components is disposed on the quick-change base, and the remaining portion is disposed on the pre-installed cassette cartridge. The at least portion and the remaining portion snap-fit each other, thereby fixing the pre-installed cassette cartridge relative to the quick-change base in the first axial direction. A locking component is also provided between the pre-installed cassette cartridge and the quick-change base to prevent the pre-installed cassette cartridge from displacing in the second axial direction perpendicular to the first axis.
[0031] Specifically, in this embodiment, the pre-installed cassette cartridge has the tape pre-installed outside the production line and adjusted and verified. The pre-installed cassette cartridge also has a built-in remaining quantity calculation system that triggers a cartridge replacement command when the remaining quantity is insufficient.
[0032] It is understood that in this embodiment, when the pre-installed cassette cartridge is installed onto the quick-change base, the pre-installed cassette cartridge and the quick-change base are fixed relative to each other in the first axial direction by the snap-fit assembly, and the pre-installed cassette cartridge and the quick-change base are fixed relative to each other in the second axial direction perpendicular to the first axis by the locking assembly, thereby ensuring a stable connection between the pre-installed cassette cartridge and the quick-change base.
[0033] Understandably, in this embodiment, the quick-change base provides the necessary support for the pre-loaded cassette cartridge. The pre-loaded cassette cartridge not only contains the tape but has also been calibrated and adjusted, allowing it to be used immediately after installation, thus improving work efficiency. The built-in remaining tape calculation system provides intelligent management functions, helping to replace the tape in a timely manner and avoiding work interruptions due to tape depletion. The snap-fit assembly ensures a secure connection between the pre-loaded cassette cartridge and the quick-change base through snap-fit action in the first axial direction, preventing loosening or detachment during use. The locking assembly functions in the second axial direction perpendicular to the first axis, further enhancing the stability between the pre-loaded cassette cartridge and the quick-change base, preventing any possible movement in the second axial direction.
[0034] Furthermore, such as Figure 2 , Figure 4 and Figure 7 As shown, the snap-fit assembly includes a snap block and a fixing member. The fixing member has a snap groove that at least partially mates with the snap block. One of the snap block and the fixing member is disposed on the support plate of the quick-change base, and the other is disposed on the fixing plate of the pre-assembled cassette body.
[0035] It is understood that the snap-fit assembly in this embodiment uses at least a portion of the snap-fit block to engage with the slot on the fastener, so that the pre-installed cartridge body and the quick-change base are stably connected in the first axial direction by snapping together. This not only improves the efficiency of installation and replacement and shortens the replacement time of cleaning tape consumables, but also ensures the reliability of the connection and reduces problems caused by loosening.
[0036] Furthermore, such as Figure 4 As shown, the support plate or fixing plate is provided with a sliding groove arranged along the second axis direction that communicates with the slot.
[0037] It is understood that, in this embodiment, by providing a sliding groove communicating with the card slot on the support plate or fixing plate, an efficient connection between the pre-assembled cassette cartridge and the quick-change base can be achieved. When the pre-assembled cassette cartridge is connected to the quick-change base via the card block, it first enters the sliding groove, and then, guided by the sliding groove, accurately slides into the card slot of the fixing component. This not only simplifies the installation process but also improves the accuracy and reliability of the connection. Simultaneously, the communication between the sliding groove and the card slot ensures that the card block has a clear guiding path before entering the card slot, reducing the skill requirements for operators and thus avoiding installation errors caused by misoperation, further improving overall assembly efficiency.
[0038] Furthermore, such as Figure 7 As shown, the card block has a T-shaped structure, and the card slot has a T-shaped structure.
[0039] Understandably, by designing the locking block and slot in a T-shape in this embodiment, higher stability and connection strength can be provided during locking operations. The T-shape increases the contact area, making it less likely for the locking block to slide or fall out within the slot, thereby improving the overall structural reliability. Simultaneously, the T-shaped locking block and slot not only simplify the assembly process but also enhance resistance to shear and tensile forces.
[0040] Furthermore, the fastener has a C-shaped structure.
[0041] It is understood that the fastener in this embodiment adopts a C-shaped structure, which can effectively accommodate and fix the T-shaped card block.
[0042] Furthermore, the snap-fit components are in three groups and arranged in a triangular pattern.
[0043] Understandably, in this embodiment, the three sets of snap-fit components are arranged in a triangular pattern, forming a stable geometry that helps improve the overall structural stability and strength. The triangular distribution effectively disperses stress, preventing structural deformation or damage, thereby extending the service life of the components.
[0044] Furthermore, such as Figure 2 and Figure 5-6 As shown, the locking assembly includes a locking limit rod and a locking groove / hole. One of the locking limit rod and the locking groove / hole is disposed on the support plate, and the other is disposed on the fixing plate. At least a portion of the locking limit rod can extend into the locking groove / hole through the first driver.
[0045] Specifically, in this embodiment, the first driver can be a drive cylinder.
[0046] It is understood that in this embodiment, when the pre-installed cassette cartridge is snapped into place with the quick-change base by the snap-fit assembly, at least a portion of the locking limit rod is driven by the second driver to extend into the locking groove / hole, thereby preventing the pre-installed cassette cartridge from moving in the second axial direction, thus achieving locking and ensuring the stability and safety of the overall structure.
[0047] Furthermore, such as Figure 5-6 As shown, a second driver is provided on the quick-change base. The power end of the second driver is connected to the take-up and unload rolls of the pre-installed cassette body through the transmission component, and drives the take-up and unload rolls to rotate.
[0048] Furthermore, the conveying assembly includes at least two drive shafts connected to the power end of the second drive via a conveyor chain / belt assembly, with at least a portion of one drive shaft extending into the take-up roll and circumferentially fixedly connected to the take-up roll; and at least a portion of the other drive shaft extending into the unwind roll and circumferentially fixedly connected to the unwind roll.
[0049] Specifically, in this embodiment, the second driver connects at least two power shafts via a conveyor chain / belt group. At least a portion of one power shaft is circumferentially fixedly connected to the take-up roll, and at least a portion of the other power shaft is circumferentially fixedly connected to the unload roll. The unload roll inside the pre-installed cassette cartridge is pre-loaded with tape. After the pre-installed cassette cartridge is installed with the quick-change base, the second driver drives the unload roll and take-up roll to rotate.
[0050] Understandably, in this embodiment, the second drive on the quick-change base is connected to the take-up and unload rolls via a conveyor assembly, ensuring continuous supply and recycling of the conveyor belt. The conveyor assembly uses a conveyor chain or conveyor belt to transmit power from the second drive to the two rolls, achieving synchronous rotation. Furthermore, the circumferential fixed connection ensures effective power transmission, avoids slippage or slippage, and guarantees stable operation of the device.
[0051] Specifically, the quick-change base and pre-installed cartridge are equipped with a QR code or RFID identification system. This system includes a reader, a signal transmission and processing circuit, and a main control unit. The reader reads the QR code or RFID tag and retrieves the information stored in it when the pre-installed cartridge is installed near the quick-change base. The signal transmission and processing circuit transmits the signal from the reader to the main control unit. The main control unit receives and processes the signal from the reader, performs automatic identification, data storage, and comparison. It extracts information from the QR code or RFID tag, such as the pre-installed cartridge's serial number, model number, and production date, and compares it with pre-stored information. If any discrepancies are found, an alert is issued to ensure that the replaced pre-installed cartridge is of the correct model.
[0052] Specifically, the remaining tape calculation system includes a pressure sensor, a signal processing unit, a calculation module, and an early warning module. The pressure sensor monitors the pressure data of the tape on the unloading roll inside the pre-loaded cassette cartridge; the signal processing unit acquires the pressure data monitored by the pressure sensor and converts it into a recognizable electrical signal; the calculation module acquires and obtains the monitored pressure data based on the electrical signal from the signal processing unit, and calculates the remaining tape amount according to a preset algorithm; the early warning module acquires the remaining tape amount obtained by the calculation module and compares it with a preset threshold. When the remaining tape amount is less than the preset threshold, it issues a cartridge replacement command, prompting the replacement of the pre-loaded cassette cartridge.
[0053] Specifically, the signal processing unit includes an analog-to-digital converter that converts analog signals into digital signals for easier subsequent processing.
[0054] Specifically, the preset algorithms include:
[0055] A mathematical model is established for the relationship between pressure and remaining tape length. The specific formula is as follows:
[0056] L = a × P + b;
[0057] Where L is the remaining length of the tape; P is the pressure data; and a and b are experimentally determined coefficients.
[0058] Understandably, by monitoring the tape usage in real time, an automatic box replacement instruction is triggered when the remaining tape is insufficient, reminding the user to replace it. This intelligent management method greatly improves the convenience and efficiency of operation.
[0059] In another aspect, the present invention provides a pad printing device, including a quick-change device for tape consumables.
[0060] It is understood that the pad printing device in this embodiment has the same beneficial effects as the tape consumable quick-change device described above, and will not be repeated here.
[0061] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
