Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically to a magnetic sheet conveying device for a magnetic sheet attaching machine. Background Technology

[0002] Magnetic snap-on packaging boxes feature magnetic strips that attract each other at the openings of the box body and lid, making opening and closing the box more stable and convenient. Currently, existing magnetic strip attaching machines, such as the packaging box magnetic strip attaching machine disclosed in publication number CN216915030U, have a core structure consisting of three parts: a conveyor belt for transporting the packaging box cardboard, a magnetic strip box for transporting the magnetic strips, and a suction nozzle for attaching the magnetic strips to the boxes; automatic attaching is achieved through the reciprocating movement of the suction nozzle.

[0003] However, the existing technologies mentioned above still have some drawbacks. Since magnetic sheets are thin metal sheets, they inevitably contain some defective ones, such as warped edges or twisted shapes. Existing technologies cannot effectively detect these defective sheets. Once a defective sheet gets stuck, the machine must be stopped, and the defective sheet must be manually removed, significantly impacting the efficiency of automated production. Furthermore, existing magnetic sheet boxes cannot automatically replenish magnetic sheets; the equipment must be paused after each sheet is filled for replenishment, resulting in low production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a magnetic sheet conveying device for a magnetic sheet attaching machine, which can automatically convey and replenish magnetic sheets in a timely manner, and can also inspect defective magnetic sheets without stopping the machine, thus significantly improving production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic sheet conveying device for a magnetic sheet attaching machine, comprising a frame, wherein a feeding device, a first feeding rack, and a second feeding rack are sequentially connected and conveying magnetic sheets on the frame; the first feeding rack is used to receive magnetic sheets from the feeding device and to feed single magnetic sheets to the second feeding rack; the second feeding rack stores the received magnetic sheets and conveys single magnetic sheets to an external attaching robot.

[0006] The present invention is further configured such that: the first feeding rack includes a first material tube, a first discharging platform and a material picker, the inlet of the first material tube receives the magnetic sheet sent out by the feeding device, the outlet is connected to the first inlet provided on the first discharging platform, and the first discharging platform sends the magnetic sheet from the first inlet to the material picker.

[0007] The present invention is further configured such that: the first discharge platform includes a first push plate located below the first feed inlet and capable of telescopic sliding, and a gap consistent with the thickness of a single magnetic sheet is left between the first push plate and the first feed inlet, and the first push plate reciprocates between the first feed inlet and the material handling hand by telescopic sliding.

[0008] The present invention is further configured such that the material picker is positioned above the second feeding rack, so that when the first push plate retracts, the magnetic sheet released by the material picker can fall into the second feeding rack.

[0009] The present invention is further configured such that: the second feeding rack includes a second material pipe and a second discharge platform, the inlet of the second material pipe corresponds to the first feeding rack, and the outlet is connected to the second inlet provided on the second discharge platform.

[0010] The present invention is further configured such that: the second discharge platform includes a second push plate located below the second feed port and capable of telescopic sliding, and a gap consistent with the thickness of a single magnetic sheet is left between the second push plate and the second feed port; when the second push plate extends, the external patching robot picks up the discharged magnetic sheet.

[0011] The present invention is further configured such that: an adhesive applicator is provided at the outlet of the second push plate, and when the external patching robot picks up the magnetic sheet, the adhesive applicator applies adhesive to the magnetic sheet.

[0012] The present invention is further configured such that: the gluing device includes a glue tank for storing glue and a rotating glue roller, the glue roller having a coating part with a width smaller than the diameter of the magnetic sheet and in contact with the glue in the glue tank; when the patching mechanism picks up the magnetic sheet, it drives the magnetic sheet through the coating part to achieve gluing.

[0013] The present invention is further configured such that the feeding device is a vibratory feeder.

[0014] In summary, this utility model has the following beneficial effects:

[0015] This invention includes a feeding device, a first feeding rack, and a second feeding rack. The feeding device uses a vibratory feeder to automatically replenish the first and second feeding racks, ensuring continuous automated production. Simultaneously, magnetic sheets are first fed and screened individually through the first feeding rack to ensure that only qualified sheets are fed to the second feeding rack. Qualified sheets are then stored in the second feed tube. When a defective sheet is encountered, it gets stuck at the first feeding rack, interrupting its feeding. However, since the second feed tube contains a certain number of stored sheets, this does not affect the subsequent feeding of the second feeding rack, allowing the equipment to continue operating normally. Before the stored sheets in the second feed tube are depleted, there is sufficient time for manual removal of the defective sheets from the first feeding rack. This prevents the entire equipment from stopping due to defective sheets, significantly improving production efficiency. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] This embodiment discloses a magnetic sheet conveying device for a magnetic sheet attaching machine, such as... Figure 1-5 As shown, the system includes a frame 1, on which a feeding device 2, a first feeding rack 31, and a second feeding rack 32 are sequentially connected and transport magnetic sheets. The first feeding rack 31 receives magnetic sheets from the feeding device 2 and feeds single magnetic sheets to the second feeding rack 32. The second feeding rack 32 stores the received magnetic sheets and transports single magnetic sheets to an external bonding robot. Specifically, the feeding device 2 is a vibratory feeder, which allows for convenient replenishment of magnetic sheets without requiring the equipment to be stopped. The operator only needs to periodically pour material into the vibratory feeder, and the vibratory feeder transports the magnetic sheets one by one through a pipe into the first feeding rack 31. The first feeding rack 31 then feeds single magnetic sheets to the second feeding rack 32. The first feeding rack 31 screens the magnetic sheets; qualified magnetic sheets are successfully fed into the second feeding rack 32 and then transported to the second feeding rack 32. 2. Magnetic sheets are stored and subsequently conveyed. If there are defective magnetic sheets, such as those with warped edges, they will be stuck at the first feeder 31 and will not enter the second feeder 32. At this time, the second feeder 32 still has enough spare magnetic sheets stored to maintain normal processing for a certain period of time. Before the second feeder 32 consumes all the stored magnetic sheets, there is enough time for manual removal of defective magnetic sheets from the first feeder 31. After removal, the first feeder 31 can resume normal receiving and conveying of magnetic sheets and restart operation. Thus, through the setting of the first feeder 31 and the second feeder 32, even if defective magnetic sheets appear, they will only stay at the first feeder 31, ensuring that the second feeder 32 and subsequent magnetic sheet application work will not be interrupted, greatly improving production efficiency. Additionally, the external patching robot in this embodiment is not shown in the accompanying drawings. Its specific structure can be found in a magnetic patching machine for packaging boxes disclosed in CN216915030U, which includes a suction nozzle, mounting base, vertical cylinder, and horizontal cylinder. This patching robot reciprocates between the second feeder 32 and the packaging box cardboard, using a suction cup or electromagnet to pick up the magnetic sheets and mount them onto the packaging box cardboard. This invention does not improve upon the patching robot, and therefore will not be described further.

[0029] Furthermore, refer to Figure 3In this embodiment, the first feeding rack 31 includes a first material pipe 311, a first discharge platform 312, and a picking hand 313. The inlet of the first material pipe 311 is provided with a funnel-shaped structure to facilitate the receiving of magnetic sheets from the feeding device 2. The outlet is connected to the first inlet 3121 provided on the first discharge platform 312. The connection method is a sleeve connection, which facilitates subsequent disassembly. The first discharge platform 312 feeds the magnetic sheets from the first inlet 3121 to the picking hand 313. The specific structure of the first discharge platform 312 includes a first push plate 3122 located below the first inlet 3121 and capable of telescopic sliding. A gap 5, consistent with the thickness of a single magnetic sheet, is left between the first push plate 3122 and the first inlet 3121. The first push plate 3122 reciprocates between the first inlet 3121 and the picking hand 313 by telescopic sliding. The power source for the reciprocating movement of the first push plate 3122 can be a cylinder 6. Specifically, Figure 3 When the first push plate 3122 is in the pushed-out state, the picker 313 can pick up the magnetic sheet on the first push plate 3122. At the same time, the picker 313 is also set above the second feeding frame 32, specifically above the second material tube 321. When the first push plate 3122 moves to the right and retracts, the picker 313 releases the magnetic sheet on it, which can fall into the second feeding frame 32, that is, the second material tube 321. Thus, the magnetic sheet conveying of the first feeding frame 31 is realized. Returning to the function of the first feeding rack 31, qualified magnetic sheets can be normally conveyed to the second feeding rack 32 in the manner described above. However, some magnetic sheets inevitably have twisted or deformed edges. These defective magnetic sheets will get stuck at the first feeding rack 31 because they cannot pass through the gap 5. At this time, an infrared detection device can be set at the outlet of the gap 5 to detect the problem. When it is found that no magnetic sheet is being fed out, a jam may have occurred. The corresponding alarm device will alert the on-site personnel, who can then pull out the first feed tube 311 to remove the jammed magnetic sheet, and the first feeding rack 31 can resume operation.

[0030] Furthermore, refer to Figure 4The second feeding frame 32 includes a second material tube 321 and a second discharge platform 322. The inlet of the second material tube 321 is also provided with a funnel-shaped structure and corresponds to the first feeding frame 31, that is, below the material picker 313 of the first feeding frame 31. The outlet is sleeved and connected to the second inlet 3221 provided on the second discharge platform 322. The second discharge platform 322 includes a second push plate 3222 located below the second inlet 3221 and capable of telescopic sliding (the second push plate 3222 is also powered by a cylinder 6). A gap 5 consistent with the thickness of a single magnetic sheet is left between the second push plate 3222 and the second inlet 3221. When the second push plate 3222 extends, the external patching robot picks up the delivered magnetic sheet. The second feed tube 321 should be relatively long to store a large number of magnetic sheets. This ensures that if the first feed rack 31 jams, there are enough magnetic sheets to sustain normal processing for a certain period. Preferably, the magnetic sheet storage in the second feed tube 321 can sustain normal processing for 10-15 minutes, allowing sufficient time for manual operation. Therefore, the magnetic sheets in the second feed rack 32 are all qualified sheets that have been screened by the second feed rack, preventing jamming. The corresponding gap 5 structure is used to feed out single magnetic sheets.

[0031] Preferably, the positions where the magnetic sheet is placed on the first push plate 3122 and the second push plate 3222 can be equipped with small magnets inside, thereby increasing the stability of the magnetic sheet being pushed on the push plate.

[0032] Furthermore, refer to Figure 4-5 A gluing device 4 is provided at the outlet of the second push plate 3222. When the external patching robot picks up the magnetic sheet, the gluing device 4 applies glue to the magnetic sheet. The gluing device 4 includes a glue tank 401 for storing glue and a rotating glue roller 402. The glue roller 402 has a coating part 4021 with a width smaller than the diameter of the magnetic sheet and in contact with the glue in the glue tank. When the patching robot picks up the magnetic sheet, it drives the magnetic sheet through the coating part 4021 to achieve gluing. Through the above structure, the coating part 4021 carries the glue in the glue tank to the surface of the coating part 4021 by rotation. Since the width of the coating part 4021 is smaller than the diameter of the magnetic sheet, when the bottom of the magnetic sheet contacts the coating part 4021, the amount of glue at the bottom of the magnetic sheet will be less, so that there will be no glue overflow when the magnetic sheet is subsequently applied.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
