Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to a multi-station false eyelash packaging box installation device. Background Technology

[0002] Existing false eyelash boxes consist of an upper and lower lid, which are usually assembled by specialized workers. Double-sided tape is applied inside the lower lid to hold the set of false eyelashes before the upper lid is closed. This method involves manual closing and tape application, which carries the potential for human error such as missing items or tape, especially for unskilled workers. Furthermore, the separation of the closing and tape application processes, coupled with the additional step of removing the tape, results in significant losses in labor and time costs, leading to low production efficiency.

[0003] Chinese patent CN106246672B discloses a pneumatic double-sided tape applicator and its applicator method. It uses double-sided tape positioning pins and product lower shell positioning pins mounted on a product fixing plate, which are respectively adapted to the positioning holes of the double-sided tape and the product lower shell. The upper part of the product fixing plate is opposite to the double-sided tape applicator pressing block, which is driven up and down by a cylinder and a support seat with a linear slide rail, thereby achieving the effect of applying double-sided tape. However, this patent mainly focuses on the reliability and accuracy of double-sided tape application, while the release paper is removed manually, which cannot meet the needs of scenarios where release paper removal is frequent. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies, such as the cumbersome process of applying adhesive to false eyelash boxes and the need to tear off release paper, by providing a multi-station false eyelash packaging box installation device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A multi-station false eyelash packaging box assembly device includes a frame, on which positioning molds are provided for each station, and a rotary positioning device for rotating each positioning mold to the next station; at least a lower cover feeding device, an adhesive dispensing device, an upper cover feeding device, a cover closing device, and a conveying device are provided along the sequential direction of each station; the device can sequentially perform the following processes: placing the lower cover, applying adhesive to the inner bottom surface of the lower cover, placing the upper cover, closing the upper and lower covers, and stacking or conveying the packaged boxes after closing; a controller for controlling the operation of each device is also installed inside the frame.

[0007] The lower cover loading device includes a storage section for storing lower covers and a loading section for sequentially placing lower covers into positioning molds at corresponding workstations. The storage section includes a transfer device for sequentially moving the lower covers to be assembled to the desired pick-up position. The loading section includes a pick-up device for removing the lower covers to be picked up and a release device for placing the removed lower covers into the positioning molds at the corresponding workstations. The pick-up device also includes an orientation component for positioning the picked-up lower cover. The orientation component includes an orientation block, an X-axis clamping mechanism, and a Y-axis clamping mechanism. The X-axis clamping mechanism and the Y-axis clamping mechanism clamp the lower cover located on the orientation block to orient the lower cover. During or after the transfer device picks up the lower cover from the storage section, the orientation component ensures that the lower cover is oriented during the process, increasing the positioning or orientation accuracy.

[0008] As a preferred embodiment, the dispensing device includes at least one dispensing head connected to an external adhesive source and a moving part for controlling the vertical and horizontal movement of the dispensing head, wherein the horizontal movement is along the length of the cover at the corresponding dispensing station. This ensures uniform and stable dispensing each time, guaranteeing the amount of adhesive applied to the eyelash product inside the box and the flatness of the application, avoiding problems such as weak adhesion or adhesive overflow caused by uneven manual dispensing.

[0009] As a preferred option, the upper cover feeding device and the lower cover feeding device have the same structure. This facilitates daily use and maintenance by operators and equipment maintenance personnel.

[0010] As a preferred embodiment: the lid-closing device includes a retainer mounted on a frame and a first fastening part and a second fastening part mounted on the retainer; the first fastening part applies force to the hinge joint of the upper and lower lids, enabling the upper and lower lids to hinge and rotate relative to each other; the second fastening part applies force to the latching joint of the upper and lower lids, enabling the upper and lower lids to latch together in the hinged state; the closing of the upper and lower lids is completed sequentially by the first fastening part and the second fastening part. This ensures smooth latching of the upper and lower lids, preventing misalignment at the hinge joint after latching, which would hinder smooth closing.

[0011] As a preferred embodiment: the conveying device includes a picking mechanism fixedly mounted on the frame and a conveying mechanism for temporarily storing packaging boxes; the conveying mechanism includes a conveyor belt, a conveyor motor for driving the conveyor belt to rotate, and a sensor located at the end of the conveyor belt; the picking mechanism picks up each packaging box and releases it at the same position, and after placing a certain number of packaging boxes, it drives the conveyor belt to work.

[0012] As a preferred option: an air source is installed inside the frame, and the lower cover feeding device, dispensing device, upper cover feeding device, closing device, and picking mechanism are all connected to the air source.

[0013] As a preferred embodiment: the frame is equipped with a moving positioning device for moving the positioning mold sequentially to the next process position, so that the positioning mold moves in a rotating or moving manner; the moving positioning device makes the positioning mold move sequentially along each workstation in a cyclical manner.

[0014] As a preferred embodiment, a detection device is provided between the conveying device and the lower cover feeding device, and between the lower cover feeding device and the dispensing device, for detecting whether there is a box cover on the positioning mold at the corresponding workstation. The detection device is electrically connected to the controller.

[0015] This invention achieves automatic capping and dispensing by setting up various devices and their cooperation. At the same time, the use of dispensing instead of double-sided tape saves the trouble of tearing off the adhesive paper caused by using double-sided tape. In addition, the dispensing has good stability and uniform dispensing. The work stations work together to avoid the occurrence of missed dispensing. After dispensing, the capping can isolate the adhesive from the outside air, prevent air flow and accelerate the curing of the adhesive. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1 As shown, the packaging box installed by this invention includes a lower cover A01 and an upper cover A02 that are hinged together. The lower cover includes a cover body A1, a hinge portion, and a fastening portion A3. The hinge portion includes a hinge buckle A21 and a hinge slot A22. The upper cover has the same structure as the lower cover. When the upper and lower covers are fastened together, the hinge buckle of the lower cover engages with the slot of the upper cover, and the hinge buckle of the upper cover engages with the slot of the lower cover. Using upper and lower covers of the same shape allows the production of both covers to be completed using only one set of molds, reducing costs.

[0027] Combination Figure 2-7 As shown, a multi-station false eyelash packaging box assembly device includes a frame 0, on which positioning molds 1 and moving positioning devices 2 are provided for each station to rotate to the next station. At least one lower cover feeding device 3, an adhesive dispensing device 4, an upper cover feeding device 5, a cover closing device 6, and a conveying device 7 are provided along the sequential direction of each station. The device can sequentially perform the following actions at each station: placing the lower cover, applying adhesive to the inner bottom surface of the lower cover, placing the upper cover, closing the upper and lower covers, and stacking or conveying the finished packaging boxes. These correspond to the lower cover feeding station, adhesive dispensing station, upper cover feeding station, cover closing station, and conveying station. A controller for controlling the operation of each device is also installed inside the frame.

[0028] An air source 8 is installed inside the frame. The lower cover feeding device, dispensing device, upper cover feeding device, and cover closing device are all connected to the air source. The air source is equipped with a negative pressure connection port and a positive pressure connection port.

[0029] The lower cover feeding device includes a storage section 31 for storing lower covers and a feeding section 32 for sequentially placing lower covers into positioning molds at corresponding workstations; the storage section includes a transfer device 311 for sequentially moving lower covers to be assembled to the desired pick-up position, and the feeding section includes a pick-up device 321 for removing lower covers to be picked up and a dispensing device 322 for placing the removed lower covers into the positioning molds at the corresponding workstations; the pick-up device also includes a directional component 33 for positioning the direction of the lower covers picked up by the pick-up device; the directional component includes a directional stop 331. X-axis clamping mechanism 332 and Y-axis clamping mechanism 333; the positioning block includes two mutually perpendicular side walls, that is, two adjacent sides of the rectangle. Both the X-axis clamping mechanism and the Y-axis clamping mechanism are provided with clamping blocks 334, and the two clamping plates correspond to the positions of the other two sides of the rectangle. When the lower cover is placed on the orientation component, the X-axis clamping mechanism and the Y-axis clamping mechanism clamp the lower cover located on the orientation block to orient the lower cover so that the direction of the picking device when picking up the lower cover is consistent with the direction of the corresponding positioning mold.

[0030] During or after the material transfer device picks up the lower cover from the storage section, if the lower cover is not properly positioned or is offset during pickup, it may not be able to be placed correctly into the positioning mold if it is placed directly onto the positioning mold. However, by setting up an orientation component, the lower cover can be oriented during the process, thereby increasing the positioning or orientation accuracy.

[0031] There is a gap between the inner wall of the positioning mold and the outer wall of the cover, which is preferably 0.3-1mm. The upper part of the inner wall of the positioning mold is provided with a guide surface for guiding the lower cover or upper cover. When the lower cover is placed, the guide surface guides the lower cover or upper cover, making it easier for the lower cover and upper cover to be placed into the positioning mold.

[0032] Both the material picking device and the material discharging device are equipped with negative pressure suction pipes 324 connected to the negative pressure connection port of the air source. The opening and closing of the suction pipes are controlled by a solenoid valve, which is electrically connected to the controller. The negative pressure suction pipes are evenly spaced to keep the lower cover horizontal when picking it up, thereby reducing the loss of positioning accuracy caused by the lower cover during picking. When the material picking device picks up the lower cover at the top of the storage section and the material discharging device picks up the lower cover in the orientation mold, the controller opens the corresponding solenoid valve, which generates negative pressure at the suction pipe and creates suction force on the lower cover, thereby stably picking up the lower cover. After the lower cover is moved to the corresponding position (inside the orientation mold or the positioning mold), the solenoid valve is closed to complete the picking up of the lower cover and reset it.

[0033] The storage unit also includes a storage rack 312 for storing the lower cover; the storage rack is arranged vertically, and multiple lower covers are stacked on the storage rack with their inner cavities facing upwards; the transfer device includes a lifting frame 313 for lifting the lower cover as a whole, and the lifting frame moves upwards by the height of one lower cover each time; the lifting frame is driven by a motor electrically connected to the controller, such as a gear and rack, and the up and down movement of the lifting frame is achieved by the forward and reverse rotation of the motor; so that each time the transfer device moves the lower cover to the orientation mold, the lifting frame moves the uppermost lower cover to the height of the previously moved lower cover, so that the next time the transfer device picks up the lower cover, it can pick up the lower cover stably and prevent the situation where it cannot pick up the lower cover due to the distance being too far.

[0034] Furthermore, the uppermost part of the storage section is equipped with a sensor or contact switch electrically connected to the controller. This sensor or contact switch detects whether there are any lower covers remaining in the storage section, allowing operators to replenish them promptly. Additionally, when the uppermost part of the storage section is equipped with a sensor, the controller also includes a counter. A display on the frame shows the counter's value. The sensor counts the removed lower covers and displays the count on the display, enabling operators to prepare replacement covers in a timely manner.

[0035] When the positioning mold moves to the lower cover loading station, the picking device picks up the lower cover located at the top of the storage section and places it into the orientation mold for initial positioning. While the picking device picks up the lower cover in the storage section, the unloading device takes out the lower cover located in the orientation mold in the previous step and puts it into the positioning mold. Thus, the initial positioning of the lower cover and the precise placement of the lower cover are achieved in a single process, thereby improving the positioning accuracy.

[0036] The upper cover feeding device and the lower cover feeding device have the same structure. The identical structure simplifies the control program and facilitates daily use and maintenance by operators and equipment maintenance personnel.

[0037] The moving positioning device is used to move the positioning molds sequentially to the next process position. The moving positioning device includes a cam divider 21 set in the frame and a rotating disk 22 that is drivenly connected to the cam divider. Each of the positioning molds is fixedly connected to the rotating disk. The cam divider is preferably an 8-station divider. As the cam divider works, the rotating disk is rotated to accurately position each station, so that each device can complete the corresponding process at the same time.

[0038] Each of the conveying device and the lower cover feeding device, and the lower cover feeding device and the dispensing device, is equipped with a detection device 9 electrically connected to the controller. These two detection devices correspond to a coverless detection station and a lower cover detection station, respectively. The two detection devices are used to detect whether there is no cover at the coverless detection station and whether there is a cover at the lower cover detection station. The detection device at the coverless detection station can only rotate to the next station when it detects that there is no workpiece on the positioning mold, and the detection device at the lower cover detection station can only rotate to the next station when it detects that there is a workpiece on the positioning mold. By setting up two detection devices, problems such as missing workpieces can be avoided, preventing issues like missed or incorrect installation.

[0039] The dispensing device includes at least one glue head 41 connected to an external glue source and a moving part 42 for controlling the vertical and horizontal movement of the glue head, wherein the horizontal movement is along the length of the lower cover at the corresponding dispensing station of the device; preferably, there are two glue heads; the mechanism for controlling the vertical and horizontal movement of the glue heads can be driven by a cylinder or motor connected to an air source; when the positioning mold with the lower cover rotates to the dispensing station, the glue head moves into the lower cover to dispense glue and moves until it has moved a set distance or after a set time, after which the glue dispensing stops and the glue head returns to its initial position. By setting up the dispensing device, the glue dispensing is uniform and stable each time, which can ensure the amount of glue and the flatness of the glue when the eyelash product is pasted in the box, avoiding the problems of uneven glue application caused by manual application, such as weak adhesion or glue overflow.

[0040] The lid-closing device includes a retainer 61 mounted on a frame and a first fastening part 62 and a second fastening part 63 mounted on the retainer. The first fastening part applies force to the hinge joint of the upper and lower lids, enabling the upper and lower lids to hinge and rotate relative to each other. The second fastening part applies force to the latching joint of the upper and lower lids, enabling the upper and lower lids to latch together in the hinged state. The force is applied at the upper end face of the upper lid near the side wall of the latching joint. An elastic roller 631 is provided at the point where the second fastening part abuts against the upper lid. This elastic roller has a buffering effect when applying force to the upper lid, preventing excessive impact on the latching joint and thus preventing it from breaking. When the lid-closing device performs a closing action, the first fastening part first latches the hinge joint of the upper and lower lids, followed by the second fastening part latching the latching joint. By performing the sequential latching actions of the hinge joint and the latching joint of the upper and lower lids, the upper and lower lids can be smoothly latched together, avoiding misalignment at the hinge joint after the latching joint is latched, which would prevent the lid from closing smoothly.

[0041] The conveying device includes a picking mechanism 71 fixedly mounted on the frame and a conveying mechanism 72 for temporarily storing packaging boxes. The conveying mechanism includes a conveyor belt 721, a conveyor motor 722 for driving the conveyor belt to rotate, and a sensor 723 located at the end of the conveyor belt. The picking mechanism picks up each packaging box, moves it to the same position, and releases it. After each release, the packaging box falls to the same position on the conveyor belt, achieving stacking of the packaging boxes. The picking mechanism is connected to the negative pressure connection port of the air source. The picking mechanism picks up the packaging boxes with their lids closed through a negative pressure suction tube similar to the material picking device. After a certain number of packaging boxes are placed, the conveyor belt is driven to work, causing the stacked packaging boxes to move towards the end of the conveyor belt. The conveyor belt moves a fixed distance each time. When the sensor at the end detects a box, it sends a signal to remind the operator to move the box in time.

[0042] This invention achieves automatic capping and dispensing by setting up various devices and their cooperation. At the same time, the use of dispensing instead of double-sided tape saves the trouble of tearing off the adhesive paper caused by using double-sided tape. In addition, the dispensing has good stability and uniform dispensing. The work stations work together to avoid the occurrence of missed dispensing. After dispensing, the capping can isolate the adhesive from the outside air, prevent air flow and accelerate the curing of the adhesive.

[0043] Example 2

[0044] This embodiment improves upon embodiment 1 as follows: the lifting frame in the lower cover feeding device and the upper cover feeding device moves synchronously; the number of lower covers in the storage rack of the lower cover feeding device is the same as the number of upper covers in the storage rack of the upper cover feeding device, so each time a lower cover or the thickness of an upper cover needs to be moved up, the lifting frame only needs to be moved once.

[0045] Since the storage section and the loading section are independent mechanisms, the early movement of the lifting frame in the upper cover loading device will not affect the operation of the loading section in the upper cover loading device. Furthermore, since the lifting frames of both move simultaneously, only one drive is needed to drive the lifting frame to rise and fall, which also makes it easier to detect whether the number of upper and lower covers is equal.

[0046] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
