Technical Field
[0001] This utility model relates to the field of button-attaching machine technology, and in particular to an automatic button-attaching machine for slotted buckles. Background Technology
[0002] Button-attaching machines are simple in structure, easy to operate, and inexpensive. They are mainly used for attaching various metal buttons and decorative snaps, and are widely used in garment factories and leather bag processing enterprises. Chinese utility model patent CN211722003U discloses an automatic button-attaching machine that can automatically feed face and bottom buttons, improving production efficiency and safety. However, it is only suitable for standard-shaped eyelet buttons. For oval-shaped groove buttons, it is impossible to ensure that the length and width of the face and bottom buttons are aligned during feeding, easily causing pressing failures, wasting materials, and requiring rework.
[0003] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an automatic buckle attaching machine for slotted buckles, which addresses the shortcomings of the prior art and solves the problem that the length and width of the face buckle and the bottom buckle are difficult to align and the pressing is prone to failure when feeding elliptical slotted buckles.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic buckle attaching machine, comprising a frame, a worktable at the upper center of the frame, a work support on the worktable, a riveting cylinder mounted on the upper end of the work support, an upper die mounted on the work support below the riveting cylinder, a lower die mounted on the worktable below the upper die, a face buckle feeding mechanism on one side of the worktable, and a bottom buckle feeding mechanism on the other side. A face buckle fixing seat mounted on the work support is located at the outlet of the face buckle feeding mechanism, and a first strip-shaped groove with a size adapted to the face buckle is located at the upper end of the face buckle fixing seat. The length of the first strip-shaped slot is aligned with the outlet of the face buckle feeding mechanism. A face buckle picking mechanism is provided between the upper mold and the working support to remove the face buckles in the first strip-shaped slot. A limiting protrusion with a shape adapted to the inner hole of the bottom buckle is provided at the upper end of the lower mold. A bottom buckle fixing seat is provided on the worktable at the outlet of the bottom buckle feeding mechanism. A second strip-shaped slot with a size adapted to the bottom buckle is provided at the upper end of the bottom buckle fixing seat. The length of the second strip-shaped slot is aligned with the outlet of the bottom buckle feeding mechanism. A bottom buckle picking mechanism is provided on one side of the bottom buckle fixing seat to remove the bottom buckles in the second strip-shaped slot, place them into the lower mold, and engage them with the limiting protrusion.
[0006] Using the above technical solution, when feeding face buckles, the face buckles are first conveyed to the first strip-shaped slot at the upper end of the face buckle fixing seat by the face buckle feeding mechanism. The first strip-shaped slot limits the face buckle, ensuring the accuracy of its position and direction. When the face buckle picking mechanism picks up the material, it can accurately position and transfer the face buckle to the upper mold. When feeding bottom buckles, the bottom buckles are first conveyed to the second strip-shaped slot at the upper end of the bottom buckle fixing seat by the bottom buckle feeding mechanism. Similarly, the second strip-shaped slot limits the bottom buckle, ensuring the accuracy of its position and direction. When the bottom buckle picking mechanism picks up the material, it can also accurately position and transfer the bottom buckle to the lower mold and engage with the limiting protrusion. Thus, when the riveting cylinder pushes the upper mold closer to the lower mold for riveting, the accuracy is guaranteed, ensuring the success rate of buckling, improving production efficiency, and saving costs.
[0007] A further configuration of the above technical solution is as follows: the face buckle feeding mechanism includes a first cylinder mounted on the working support above the face buckle fixing seat, a second cylinder mounted on the side of the working support, an upper mold fixing seat sleeved on the lower end of the upper mold, and a first linear slide rail mounted on the side of the working support. The slider of the first linear slide rail is fixedly connected to the upper mold fixing seat. The movable end of the second cylinder is connected to the side of the upper mold fixing seat and can drive the upper mold fixing seat to move horizontally back and forth along the first linear slide rail. A sliding sleeve is provided between the upper mold and the upper mold fixing seat, and the upper mold can slide up and down relative to the upper mold fixing seat. A first limiting plate is provided at the upper end of the upper mold. A first return spring is provided on the upper mold sleeve. One end of the first return spring abuts against the first limiting plate, and the other end abuts against the sliding sleeve. When the movable end of the first cylinder extends, it can abut against the top end of the upper mold. A punch is provided at the lower end of the upper mold. The lower end of the punch has a punch tongue. The shape of the punch tongue is configured to match the shape and size of the inner hole of the face buckle, so that the punch tongue can be inserted into the inner hole of the face buckle with interference.
[0008] Using the above technical solution, during the buckle picking process, the movable end of the second cylinder retracts, first driving the upper mold fixing seat and the upper mold to move along the first linear slide rail to above the buckle fixing seat. Then, the movable end of the first cylinder extends downward to press against the top of the upper mold. The upper mold slides downward relative to the upper mold fixing seat and squeezes the first return spring. The upper mold drives the punch downward and makes the punch tongue insert into the inner hole of the buckle with interference. Then, the movable end of the first cylinder retracts and no longer presses against the upper mold. Under the elastic force of the first return spring, the upper mold moves upward to reset. The punch tongue drives the buckle to disengage from the first strip groove of the buckle fixing seat. Then, the movable end of the second cylinder extends to drive the upper mold fixing seat and the upper mold to the riveting position, thus completing one automatic buckle picking.
[0009] A further provision of the above technical solution is that: a first guide rod is connected to one side of the first limiting plate, and a guide block that is slidably connected to the first guide rod is provided on the side of the upper mold fixing seat.
[0010] By adopting the above technical solution, the guide rod and guide block set between the first limiting plate and the upper mold fixing seat can ensure the stability of the upper mold's up and down movement, and also ensure that the punch will not deflect and can always be aligned with the inner hole of the face buckle.
[0011] A further configuration of the above technical solution is as follows: the upper mold has a hollow groove at its lower end, the upper end of the punch is fixedly installed at the lower end of the hollow groove, the punch tongue is slidably connected to the punch and its lower end extends out of the punch and its upper end is provided with a limiting ring, the limiting ring has a limiting post at its center, the limiting post is fitted with a second return spring, one end of the second return spring abuts against the limiting ring and the other end abuts against the bottom wall of the upper end of the hollow groove.
[0012] Using the above technical solution, when the punch is subjected to upward pressure, it will squeeze the second return spring and slide relative to the punch, thereby offsetting part of the impact force and playing a buffering role.
[0013] A further configuration of the above technical solution is as follows: a third cylinder is installed at the lower end of the working support, a right-angle mounting plate is installed on the movable end of the third cylinder, the face buckle fixing seat is fixedly installed on the right-angle mounting plate, the lower end of the punch is set as a cone shape with a smaller bottom and a larger top, and a first vertical clearance groove is provided in the middle of the first strip-shaped slot.
[0014] Using the above technical solution, when the movable end of the third cylinder retracts, it drives the first strip-shaped slot of the face buckle fixing seat to align with the outlet of the face buckle feeding mechanism. After the face buckle is transferred into the first strip-shaped slot, the movable end of the third cylinder extends a short distance, so that the first strip-shaped slot is misaligned with the outlet of the face buckle feeding mechanism, thus preventing the face buckles from being repeatedly stacked into the first strip-shaped slot. At the same time, the side of the face buckle fixing seat can block the face buckles at the outlet of the face buckle feeding mechanism to prevent them from falling off.
[0015] A further provision of the above technical solution is that: the working support is also provided with a positioning baffle, and when the movable end of the second cylinder extends, it can drive the upper mold fixing seat to move to abut against the positioning baffle. The upper mold fixing seat is equipped with a first buffer, and the movable end of the first buffer can abut against the positioning baffle.
[0016] By adopting the above technical solution, the positioning baffle limits the upper mold fixing seat, ensuring that the upper mold can accurately reach the riveting position; the first buffer installed on the upper mold fixing seat can offset the impact force of the upper mold fixing seat on the positioning baffle, avoiding damage to the parts.
[0017] A further configuration of the above technical solution is as follows: the bottom clamping material handling mechanism includes a lifting seat mounted on the workbench, a lifting plate slidably connected above the lifting seat, a slide cylinder mounted on the lifting plate, and a gripper cylinder mounted on the slider of the slide cylinder. A fourth cylinder is installed between the lifting seat and the lifting plate. Second guide rods are installed on both sides of the lifting plate at the fourth cylinder. The second guide rods are slidably connected to the lifting seat up and down. A fifth cylinder is also installed on the workbench. A lower mold fixing seat is fixedly installed at the lower end of the lower mold. A second linear slide rail is installed on the workbench below the lower mold fixing seat. The slider of the second linear slide rail is fixedly connected to the bottom of the lower mold fixing seat. The movable end of the fifth cylinder is fixedly connected to the lower mold fixing seat.
[0018] Using the above technical solution, during the bottom buckle material handling process, the slide cylinder drives the gripper cylinder to move above the second strip-shaped slot of the bottom buckle fixing seat. Then, the movable end of the fourth cylinder retracts, driving the slide cylinder and the gripper cylinder to descend together. During this process, the gripper of the gripper cylinder is in a retracted state and inserts into the inner hole of the bottom buckle before opening, fixing the bottom buckle on the gripper. The fourth cylinder drives the gripper cylinder to rise again. Then, the slide cylinder drives the gripper cylinder to move above the limiting protrusion of the lower mold. The fourth cylinder drives the gripper cylinder to descend again, so that the gripper approaches the limiting protrusion and releases the bottom buckle. The bottom buckle then falls and is locked onto the limiting protrusion. The fourth cylinder drives the gripper cylinder to rise again. Finally, the fifth cylinder drives the lower mold fixing seat and the lower mold together to move along the second linear slide rail to the riveting position, thus completing one automatic bottom buckle material handling cycle.
[0019] A further provision of the above technical solution is as follows: an operating platform is provided at the end of the workbench near the manual operation side; a U-shaped limiting groove is provided on the side of the operating platform near the lower mold; a second buffer is installed on the workbench; the movable end of the second buffer can abut against the lower mold fixing seat; a third buffer is installed on the side of the lower mold fixing seat; the movable end of the third buffer can abut against the operating platform.
[0020] Using the above technical solution, the U-shaped limiting groove on the operating table allows the lower die to be inserted and aligned for positioning, enabling the lower die to move accurately to the riveting position; the second buffer can reduce the impact force when the lower die fixing seat moves to the material picking position; and the third buffer can reduce the impact force of the lower die on the limiting groove of the operating table, avoiding damage to the parts.
[0021] A further configuration of the above technical solution is as follows: a sixth cylinder is installed on the side of the bottom buckle fixing seat, a second limiting plate is installed on the movable end of the sixth cylinder, a third strip-shaped groove is provided at the end of the second limiting plate near the second strip-shaped groove, the groove width of the third strip-shaped groove is smaller than the groove width of the second strip-shaped groove, the sixth cylinder can drive the second limiting plate to move to the position where the third strip-shaped groove is above the second strip-shaped groove, and a second vertical clearance groove is provided in the middle of the second strip-shaped groove.
[0022] Using the above technical solution, before the gripper cylinder removes the bottom buckle, the sixth cylinder first drives the second limiting plate closer to the bottom buckle fixing seat, so that the second limiting plate moves to a position where the third strip groove is above the second strip groove. Since the width of the third strip groove is smaller than the width of the second strip groove, it can limit the upper end of the bottom buckle, so that the bottom buckle remains stable. After the gripper of the gripper cylinder descends and passes through the third strip groove, the second strip groove and the second clearance groove in sequence and finally fixes the bottom buckle, the sixth cylinder drives the second limiting plate away from the bottom buckle fixing seat, so that the third strip groove no longer limits the bottom buckle, making it convenient for the gripper cylinder to remove the bottom buckle from the second strip groove.
[0023] A further configuration of the above technical solution is as follows: the face buckle feeding mechanism includes a first vibrating plate and a straight vibrator mounted on the workbench. A face buckle flow channel is installed on the upper end of the straight vibrator. One end of the face buckle flow channel is aligned with the discharge port of the first vibrating plate, and the other end is aligned with the first strip groove of the face buckle fixing seat. A face buckle limiting plate is provided on one side of the upper end of the face buckle flow channel. The bottom buckle feeding mechanism includes a second vibrating plate, and the discharge port of the second vibrating plate is aligned with the second strip groove of the bottom buckle fixing seat.
[0024] Using the above technical solution, when feeding the face buckle, the face buckle is first transported to the face buckle flow channel on the straight vibrator by the first vibrating plate, and then transported to the first strip slot of the face buckle fixing seat by the face buckle flow channel; when feeding the bottom buckle, the bottom buckle is transported to the second strip slot on the bottom buckle fixing seat by the second vibrating plate.
[0025] The beneficial effects achieved by this utility model are as follows: by limiting the front buckle and the bottom buckle respectively through the first strip groove of the front buckle fixing seat and the second strip groove of the bottom buckle fixing seat, the front buckle is fixed to the upper mold by the front buckle picking mechanism and the bottom buckle is transferred to the lower mold and snapped into the limiting protrusion by the bottom buckle picking mechanism. This ensures that the front buckle and the bottom buckle are aligned in the length direction during riveting, improves the success rate of picking and buckling, increases production efficiency, and saves costs.
