Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example content: Please see Figure 1 A button-attaching machine that facilitates mold replacement is provided, including a workbench 1. A button-attaching machine 6 and a vibrating material tray 8 are fixedly installed on the upper side of the workbench 1. The workbench 1 is an existing component consisting of a cabinet and four support legs, which serves a supporting function. The button-attaching machine 6 and the vibrating material tray 8 are existing equipment. The button-attaching machine 6 is used to provide power for attaching buttons, and the vibrating material tray 8 is located on the left side of the button-attaching machine 6 to continuously provide buttons.

[0017] A frame 5 is mounted on the front side of the button attaching machine 6 via a translation mechanism 3. An upper mold 9 is mounted on the upper inside of the frame 5 via a reset mechanism 4, and a lower mold 11 is mounted on the lower inside of the frame 5 via a reset mechanism 4. The lower mold 11 is located directly below the upper mold 9. The upper mold 9 and the lower mold 11 can move vertically via the reset mechanism 4. The translation mechanism 3 is used to translate the frame 5 left and right, thereby simultaneously switching the corresponding upper mold 9 and lower mold 11 below the button attaching machine 6.

[0018] The workbench 1 is fixedly installed with a first cylinder 2 for lifting the lower mold 11, and the top of the workbench 1 is provided with a first through slot for aligning the first cylinder 2. The first cylinder 2 is located directly below the punching head of the button attaching machine 6. The first cylinder 2 is set vertically. When in use, the push rod of the first cylinder 2 passes upward through the first through slot to lift the corresponding lower mold 11 and make it enter the working position.

[0019] The upper side of the vibrating feeder 8 is equipped with a feeding mechanism 7 for transferring buttons. The frame 5 has a second through slot for aligning the upper mold 9 and the lower mold 11. The upper second through slot is for the punch head of the button attaching machine 6 to pass through, and the lower second through slot is for the push rod of the first cylinder 2 to pass through.

[0020] To meet the usage requirements of button types: There are three upper molds 9 and three lower molds 11. The lower side of the upper mold 9 is provided with a stamping column for stamping buttons, and the top of the lower mold 11 is provided with a holding slot for placing buttons; thus forming three pairs of mold groups that meet different sizes of buttons, which is convenient for switching applications.

[0021] Please see Figure 2 The structure of translation mechanism 3: The translation mechanism 3 includes a horizontally arranged linear guide rail 31 and a rodless cylinder 32. The rear sides of both the linear guide rail 31 and the rodless cylinder 32 are fixedly assembled to the button attaching machine 6, and the slides of both the linear guide rail 31 and the rodless cylinder 32 are fixedly assembled to the frame 5. The linear guide rail 31 is used to horizontally support the frame 5 and allow the frame 5 to move horizontally, while the rodless cylinder 32 is used to provide the action of horizontal movement to switch the mold group corresponding to the button attaching machine 6.

[0022] Structure of reset mechanism 4: The reset mechanism 4 includes a spring 41, a pin 42, and a sleeve 43. Three pairs of pins 42 are fixedly installed on the upper and lower sides of the frame 5. Each pin 42 is slidably mounted with a sleeve 43. Each pair of sleeves 43 on the upper side is fixedly assembled with the upper mold 9, and each pair of sleeves 43 on the lower side is fixedly assembled with the lower mold 11. The pin 42 is fitted with a spring 41, and the spring 41 abuts against the pin head of the pin 42 and the sleeve 43.

[0023] When the punching head of the button-attaching machine 6 applies pressure to the upper mold 9, it can move downward through the cooperation of the upper sleeve 43 and the pin 42. When the push rod of the first cylinder 2 applies pressure to the lower mold 11, it can move upward through the cooperation of the lower sleeve 43 and the pin 42. After the punching head of the button-attaching machine 6 and the push rod of the first cylinder 2 are reset, the upper spring 41 is used to provide an upward reset force to the upper mold 9, while the lower spring 41 is used to provide a downward reset force to the lower mold 11.

[0024] Please see Figure 3 The structure of the delivery mechanism 7: The feeding mechanism 7 includes a second cylinder 71, a push-pull electromagnet 72, and a pneumatic gripper 73. Two push-pull electromagnets 72 are fixedly installed on the upper side of the vibrating material tray 8. The same second cylinder 71 is fixedly installed between the output rods of the push-pull electromagnets 72. The two push-pull electromagnets 72 are located on the front and rear sides of the second cylinder 71, respectively. The second cylinder 71 is horizontally set and the push-pull electromagnets 72 are vertically set. A pneumatic gripper 73 for clamping buttons is fixedly installed at the output end of the second cylinder 71.

[0025] The pneumatic gripper 73 is an existing component with two opposing gripper heads. When loading is required, the push-pull electromagnet 72 is energized to retract the armature, causing the second cylinder 71 to move down and align the gripper heads of the pneumatic gripper 73 with the buttons delivered from the rightmost end of the vibrating material tray 8. Then, the pneumatic grippers 73 move their gripper heads closer to each other to hold the buttons. After that, the push-pull electromagnet 72 is de-energized, extends the armature, and lifts the second cylinder 71. The second cylinder 71 extends a push rod to send the pneumatic gripper 73 to the lower mold 11 above the first cylinder 2. The push-pull electromagnet 72 moves the second cylinder 71 down once more, and at the same time, the pneumatic gripper 73 releases the buttons, allowing the buttons to be placed in the holding slot of the lower mold 11. After completion, it is reset and ready for use.

[0026] A support platform 10 is fixedly installed in the middle of the interior of the frame 5. The support platform 10 has a third through groove for the lower mold 11 to pass through. When the lower mold 11 is lifted, it enters the third through groove. The upper surface of the lower mold 11 is flush with the upper surface of the support platform 10. The support platform 10 is used to place the fabric to be processed, which is conducive to flat placement and alignment with the position where the buttons are to be installed.

[0027] The vibrating material tray 8, the first cylinder 2, the second cylinder 71, the push-pull electromagnet 72 and other electrical components are electrically connected to the controller on the button attaching machine 6. When in use, the button attaching machine 6 is connected to a foot switch, and the punching action of the button attaching machine 6 is controlled by the foot pedal.

[0028] The working principle of this embodiment: Mold switching: As needed for the type of button to be processed, control the translation mechanism 3 to drive the frame 5 to move horizontally, so that the upper mold 9 and lower mold 11 of the corresponding size are aligned with the punch head and the first cylinder 2 of the button attaching machine 6.

[0029] Button feeding: The vibrating feeder 8 continuously outputs buttons to the picking position. The feeding mechanism 7 clamps the button once and puts it into the holding slot of the lower mold 11. Then it resets. After that, the push rod of the first cylinder 2 pushes the corresponding lower mold 11 upward so that its upper surface is flush with the support table 10, and drives the button into the stamping position. At this time, the fabric can be placed on the support table 10 and aligned with the button.

[0030] Button sewing operation: The foot switch triggers the stamping action, the stamping head of the button sewing machine 6 presses down, and the upper mold 9 presses the button onto the fabric. After completion, the first cylinder 2 and the button sewing machine 6 are reset, making it easy to insert the button again.
