Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, and in particular to a stamping loading and unloading device. Background Technology

[0002] In the stamping process, workpieces need to be loaded, stamped, and unloaded. Traditional stamping loading and unloading is mostly done manually, which is not only labor-intensive and inefficient, but also poses certain safety hazards, as operational errors can easily lead to accidents.

[0003] To address these issues, some automated stamping loading and unloading devices have emerged. However, most existing devices are complex in structure, cumbersome to operate, and lack precision in position switching during loading and unloading, affecting the quality and efficiency of stamping processes. Furthermore, existing pick-and-place and unloading mechanisms also have shortcomings in use, such as unstable workpiece handling and unloading, and uneven unloading.

[0004] Therefore, a stamping loading and unloading device is needed that is simple in structure, easy to operate, has precise position switching, stable loading and unloading, and smooth unloading. Summary of the Invention

[0005] To address the technical problems existing in the background art, the present invention proposes a stamping loading and unloading device.

[0006] This invention proposes a stamping loading and unloading device, including an upper die and a lower die of a stamping machine body, and a conveyor belt located on the side of the stamping machine body; a tilting and lifting mechanism is installed on the side wall of the stamping machine body, and a pick-up and unloading mechanism are respectively provided on both sides of the middle part of the mechanism, and the two are on the same horizontal plane; when the tilting and lifting mechanism is activated, the pick-up and unloading mechanism and the unloading mechanism form three position states:

[0007] When the unloading mechanism is above the conveyor belt, the pick-and-place mechanism is located between the upper and lower dies;

[0008] When the pick-and-place mechanism is above the conveyor belt, the unloading mechanism is located between the upper and lower dies;

[0009] When both avoid the conveyor belt and the area between the upper and lower dies, the stamping machine can perform the stamping operation, that is, the upper and lower dies close together.

[0010] Preferably, the tilting and lifting mechanism includes a top frame and a bottom frame, which are respectively fixed to the upper and lower parts of the side wall of the stamping machine body;

[0011] A drive unit is installed on the top frame. A sleeve is fixedly connected to the output shaft end of the drive unit. A rotating shaft is sleeved at the bottom of the sleeve, and the rotating shaft and the sleeve are connected by a spline shaft.

[0012] A telescopic rod is vertically installed on the base frame, and the top end of the telescopic rod is coaxially and rotatably connected to the bottom end of the rotating shaft.

[0013] Preferably, the picking and placing mechanism includes a frame, on which an air pump is fixedly mounted, and at its bottom are multiple sets of suction cups. The air pump is used to control the suction cups to pick up and release the workpiece.

[0014] Preferably, the unloading mechanism includes a bracket and a lever. The bracket is L-shaped, with a long side and a short side. The bottom ends of the long side of the bracket are respectively connected to mounting brackets. The two sets of mounting brackets are provided with extensions extending in the opposite direction to the short side of the bracket. The middle of both sides of the lever is rotatably connected between the middle of the two sets of extensions. Its bottom is inclined towards the side closer to the short side of the bracket, and its top is inclined towards the side closer to the extension. A spring is connected between its top and the long side of the bracket. A rotating rod is rotatably connected between the ends of the extensions. A protrusion is provided in the middle of the rotating rod, which is located below the upper part of the lever. A motor is installed on the extension, and the motor is used to drive the rotating rod to rotate.

[0015] Preferably, a collection box is installed on the back side of the stamping machine body.

[0016] Preferably, the inside of the collection box is provided with a cushioning pad, which is made of an elastic material.

[0017] Preferably, the bottom of the frame is provided with an adjusting slide rail for mounting suction cups. The suction cups are slidably connected to the adjusting slide rail via a slider, and the slider is provided with a locking element for fixing the position.

[0018] The stamping loading and unloading device proposed in this invention can switch between three position states of the picking and unloading mechanism and the unloading mechanism by setting a tilting and lifting mechanism, so as to meet the different needs of loading, unloading and stamping operations. The position switching is precise, which improves the automation level and work efficiency of the device.

[0019] The tilting and lifting mechanism drives the sleeve and rotating shaft to rotate through the drive component, while the telescopic rod realizes the lifting function. It has a simple structure and stable and reliable operation.

[0020] The pick-and-place mechanism uses an air pump to control the suction cup to pick up and release the workpiece, ensuring stable and reliable pick-and-place. The bottom of the frame is equipped with an adjustable slide rail, which can adjust the position of the suction cup according to the size of the workpiece, thus improving the versatility of the device.

[0021] The unloading mechanism is driven by a motor to rotate a rotating rod, which in turn causes the convex strip to press against the push plate. The spring force then moves the push plate to smoothly eject the processed workpiece, resulting in smooth and efficient unloading.

[0022] The collection box installed on the back of the stamping machine body can collect the processed workpieces. The buffer pad inside the collection box can prevent the workpieces from being damaged during the collection process, thus protecting the quality of the workpieces.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] The tilting and lifting mechanism 3 includes a top frame 301 and a bottom frame 302, which are respectively fixed to the upper and lower parts of the side wall of the stamping machine body 1. A driving component 303 is installed on the top frame 301, and a sleeve 304 is fixedly connected to the output shaft end of the driving component 303. A rotating shaft 305 is sleeved at the bottom of the sleeve 304, and the rotating shaft 305 and the sleeve 304 are connected by a spline shaft. A telescopic rod 306 is vertically installed on the bottom frame 302, and the top end of the telescopic rod 306 is coaxially rotatably connected to the bottom end of the rotating shaft 305.

[0035] The picking and placing mechanism 4 includes a frame, on which an air pump 402 is fixedly mounted, and at its bottom are multiple sets of suction cups 401. The air pump 402 is used to control the suction cups 401 to pick up and release the workpiece. The bottom of the frame is provided with an adjusting slide rail for mounting the suction cups 401. The suction cups 401 are slidably connected to the adjusting slide rail via a slider, and the slider is provided with a locking element for fixing the position.

[0036] The unloading mechanism 5 includes a bracket 501 and a lever 503. The bracket 501 is L-shaped with a long side and a short side. The bottom ends of the long side of the bracket 501 are respectively connected to mounting brackets 502. The two sets of mounting brackets 502 are provided with extensions extending in the opposite direction to the short side of the bracket 501. The lever 503 is rotatably connected between the middle of the two sets of extensions on both sides. Its bottom is inclined towards the side closer to the short side of the bracket 501, and its top is inclined towards the side closer to the extension. A spring 504 is connected between its top and the long side of the bracket 501. A rotating rod 505 is rotatably connected between the ends of the extensions. A protrusion 506 is provided in the middle of the rotating rod 505. The protrusion 506 is located below the upper part of the lever 503. A motor 507 is installed on the extension. The motor 507 is used to drive the rotating rod 505 to rotate.

[0037] The stamping machine body 1 has a collection box 6 installed on its back side; the collection box 6 has a buffer pad inside, which is made of elastic material.

[0038] In this embodiment, during operation:

[0039] Loading process: The tilting and lifting mechanism 3 is activated, positioning the pick-and-place mechanism 4 above the conveyor belt 2. At this time, the unloading mechanism 5 is positioned between the upper mold 101 and the lower mold 102. The conveyor belt 2 transports the workpiece to be processed to below the pick-and-place mechanism 4. The telescopic rod 306 retracts, the air pump 402 operates, controlling the suction cup 401 to pick up the workpiece, and the telescopic rod 306 extends. Then, the tilting and lifting mechanism 3 is activated, moving the pick-and-place mechanism 4 between the upper mold 101 and the lower mold 102, placing the workpiece on the lower mold 102.

[0040] Stamping process: The tilting and lifting mechanism 3 is activated, so that the pick-up and unloading mechanism 4 and the unloading mechanism 5 both avoid the area between the conveyor belt 2 and the upper die 101 and the lower die 102. The stamping machine body 1 is working, and the upper die 101 and the lower die 102 close to perform stamping processing on the workpiece.

[0041] Unloading process: After stamping, the tilting and lifting mechanism 3 is activated, positioning the unloading mechanism 5 between the upper die 101 and the lower die 102, with the pick-and-place mechanism 4 positioned above the conveyor belt 2. The motor 507 drives the rotating rod 505 to rotate, causing the protrusion 506 to press against the upper part of the guide plate 503, compressing the spring 504. When the protrusion 506 rotates to the critical point with the back of the guide plate 503, it no longer contacts the guide plate 503, the spring 504 rebounds, and the bottom of the guide plate 503 generates a rebound force, ejecting the processed workpiece into the collection box 6. Simultaneously, the pick-and-place mechanism 4 picks up the workpiece from the conveyor belt 2 again for the next processing cycle.

[0042] Note: To prevent the wiring on motor 507 and air pump 402 from malfunctioning, drive unit 303 adopts a forward and reverse rotation mode.
