Description

Technical Field

[0001] This application relates to the field of flat die-cutting production, and in particular to a method for applying cotton and a cotton-applying machine for implementing the method. Background Technology

[0002] When applying sponge to a flat die, the sponge applicator first cuts out small pieces of sponge from a whole piece of sponge placed on the platform as required. Then, through processes such as grasping, gluing, and pasting, the small pieces of sponge are finally pasted onto the flat die.

[0003] Existing sponge applicator equipment often integrates the processes of sponge cutting, gripping, gluing, and pasting into a single machine. These processes are performed sequentially and in a loop, resulting in the sponge cutting process often taking up a significant amount of time during production. This forces subsequent gripping, gluing, and pasting processes to stop and wait, leading to low production efficiency and waste.

[0004] Therefore, there is a need for a sponge-applying method that eliminates the need to wait for cutting and a sponge-applying machine that implements this method, separating the sponge cutting process from the subsequent grasping, gluing, and pasting processes. Summary of the Invention

[0028] like Figures 1 to 8 As shown, an embodiment of this application provides a method for applying cotton padding, which includes the following steps: Step 1. Set up at least one movable cutting platform 12 and a movable cutting tool set 13; Step 2. In the cutting area, the cutting platform 12 uses the cutting tool group 13 to divide the whole piece of sponge into sponge strips or sponge blocks. After the division is completed, the cutting platform 12 moves to the unloading area to wait for the material to be picked up. Step 3. Set up the cotton-applying tool group 24, which, together with the cutting tool group 13, is driven to move by an independent drive device; Step 4. The sponge applicator set 24 moves to the material feeding area to grab the divided sponge strips or sponge blocks, and then performs the gluing and pasting process to paste the sponge strips or sponge blocks onto the flat die. Step 5. Repeat step 4 until all the sponge strips or sponge blocks that meet the usage requirements on the cutting platform 12 are grabbed; When step 2 is completed, another cutting platform 12 moves to the cutting area and step 2 is repeated; Thus, once all the sponge strips or sponge blocks on one of the cutting platforms 12 in step 5 have been grabbed, another cutting platform 12 can provide the separated sponge strips or sponge blocks, and multiple cutting platforms 12 can be used in a cycle.

[0029] In step 1, the cutting platform 12 is movably mounted on the first frame, and the cutting tool set 13 is movably mounted on the first support, with the cutting tool set 13 located above the cutting platform 12.

[0030] The cotton-applying tool group 24 and the cutting tool group 13 are each driven by an independent drive device, so that the cotton-applying tool group 24 and the cutting tool group 13 can work simultaneously without waiting.

[0031] like Figures 1 to 8 As shown, a sponge applicator includes a sponge cutting device 1 and a sponge applicator 2. The sponge cutting device 1 includes a first frame 11, which is provided with a feeding area and a cutting area. At least one cutting platform 12 is reciprocally disposed on the feeding area and the cutting area, and a cutting tool set 13 is movably disposed on the cutting area.

A cotton-applying tool set 24 is provided on the XYZ three-axis feeding mechanism 23 for grabbing the material in the feeding area to the die template placement area 22 and pasting it onto the flat die.

[0032] In other embodiments, a robotic arm can be used instead of the XYZ three-axis feeding mechanism 23, as long as it can move to the unloading area of ​​the first frame 11 to pick up materials.

[0033] The sponge cutting device 1 includes a first frame 11, which is divided into a feeding area and a cutting area. It includes at least one cutting platform 12, which can reciprocate between the feeding area and the cutting area. A cutting tool set 13 is movably provided above the cutting area.

[0034] exist Figure 2 In the process, the left end of the first frame 11 is the unloading area, the middle of the first frame 11 is the cutting area, and the right end of the first frame 11 is the loading area. The cutting platform 12 moves to the loading area and a whole piece of sponge is placed on it. The cutting tool group 13 cuts the sponge in the cutting area. The cutting platform 12 moves to the unloading area to wait for unloading. The material gripped by the XYZ three-axis feed mechanism 23 of the sponge applicator 2 in the unloading area is the cut sponge strip or sponge block that meets the usage requirements.

[0035] Specifically, the sponge cutting device 1 includes a first frame 11, which includes at least one cutting platform 12. The cutting platform 12 is movably mounted on the first frame 11. When the number of cutting platforms 12 is greater than one, multiple cutting platforms 12 are arranged longitudinally. The cutting tool group 13 is movably mounted on the cutting platform 12.

[0036] In other embodiments, the cutting platform 12 is not limited to being laterally movable on the first frame 11, but only needs to be able to move to the designated unloading area. The cutting platform 12 is also not limited to being longitudinally movable on the cutting tool set 13, but only needs to be able to cooperate with the cutting platform 12 to divide the sponge into the required sponge strips and sponge blocks.

[0037] In this embodiment, there are two cutting platforms 12. During use, a whole sheet of sponge is first cut on one cutting platform 12 into sponge strips or blocks of appropriate size as required. This allows the sponge-attaching device 2 to proceed without waiting for the sponge to be cut during subsequent processes such as gripping the sponge, applying adhesive, and attaching the sponge to the flat die. When the sponge on one cutting platform 12 is used up, the whole sheet of sponge on the other cutting platform 12 has already been cut. Thus, the two cutting platforms 12 are used cyclically, improving production efficiency.

[0039] A slide rail 14 is provided laterally on the first frame 11, and the cutting platform 12 is slidably mounted on the slide rail 14.

[0041] It also includes a platform drive mechanism 15, which is fixed to the bottom of the cutting platform 12 or the first frame 11.

[0043] The platform drive mechanism 15 can be a belt drive structure, a screw drive structure, a cylinder, a hydraulic cylinder, or a motor.

[0044] In other embodiments, other power sources may be used, as long as they can drive the cutting platform 12 to move laterally back and forth.

[0045] A plurality of clamping devices 16 are provided on one side of the cutting platform 12 for fixing the sponge to be cut placed on the cutting platform 12.

[0046] In this embodiment, there are three clamping devices 16 located on one side of the cutting platform 12.

[0047] In other embodiments, a clamping device 16 may also be added to the other side of the cutting platform 12.

[0048] Ventilation openings can also be set on the cutting platform 12. Vacuuming equipment can be connected to the ventilation openings to create a vacuum, thereby forming a negative pressure on the upper surface of the cutting platform 12 to adsorb and fix the sponge.

[0049] The clamping device 16 is a cylinder 161 arranged axially upwards on the output axis. A clamping block 162 is fixed on the cylinder 161 shaft. The cylinder 161 is fixed to one side of the cutting platform 12.

[0050] In other embodiments, other clamping devices 16 can also be used, as long as they can fix the sponge to the upper surface of the cutting platform 12, so as to prevent the sponge from shaking or shifting during cutting.

[0051] A longitudinally movable cutting mounting base 17 is provided above the first frame 11, and the cutting tool assembly 13 is fixed on the cutting mounting base 17. Specifically, a longitudinal feed device 18 is provided on the first frame 11, and the cutting mounting base 17 is fixed on the longitudinal feed device.

[0052] In other embodiments, the cutting tool assembly 13 may also be mounted on a robotic arm, so that the cutting tool assembly 13 can move longitudinally or even laterally.

[0053] The cutting tool assembly 13 includes a lifting part, a rotating part, and a tool assembly. The lifting part is fixed on the cutting mounting base 17, the rotating part is disposed on the lifting part, and the tool assembly is disposed on the rotating part.

[0054] The lifting part includes a lifting power device 311 and a lifting base 312; the rotating part includes a rotating power device 321, a rotating seat 322 and a rotating body 323; and the tool assembly includes a cutter 331 and a cutter power device 332 that drives the cutter 331 to vibrate up and down for cutting.

[0058] The cutting tool assembly 13 is described in the applicant's prior patent application, where it is referred to as the cutting tool head.

[0059] In using this invention, a whole sheet of sponge is cut on a cutting platform 12. The sponge is fixed to the cutting platform 12 by a clamping device 16. In other embodiments, ventilation openings can be added to the cutting platform 12 to adsorb and fix the sponge to the cutting platform 12 through negative pressure. The cutting tool descends to the whole sheet of sponge according to preset requirements for cutting. The cutting tool assembly 13 moves longitudinally, cooperating with the lateral movement of the cutting platform 12, thereby dividing the whole sheet of sponge into sponge strips or sponge blocks that meet the requirements. After the whole sheet of sponge on one cutting platform 12 is divided, the cutting tool assembly 13 moves to another cutting platform 12 to cut another whole sheet of sponge. The two cutting platforms 12 are used in rotation to improve production efficiency.

[0060] The cotton-applying tool set 24 includes at least one of the following: a gripper head for grasping material, a detection mechanism for detecting the position of the slit or the height of the blade after mounting, and a dispensing tool head for dispensing adhesive onto the material or flat die. The cotton-applying tool set 24 can move to the unloading area of ​​the first frame 11 to pick up material.

[0061] The gripper head, detection mechanism, and dispensing tool head are described in the applicant's prior patent application. The gripper head is also called a material handling tool set, gripper mechanism, etc., and the dispensing tool head is also called an adhesive application tool head.

[0062] This invention is reasonably and ingeniously designed, with multiple cutting platforms.
