However, setting up the loading and unloading equipment separately will occupy a large working production space, and the total manufacturing cost of producing the loading and unloading equipment is also relatively expensive. Therefore, in the existing punching production line, there is also a device that combines the loading and unloading equipment into one to perform loading and unloading work. However, the current integrated loading and unloading equipment requires a pick-and-place assembly for picking up and placing the punching workpiece. After the punched workpiece is transferred through the pick-and-place assembly, the workpiece to be punched is retrieved and placed on the placement table.

[0029] In order to describe the present invention in detail, a punching loading and unloading device and a punching production line of the present invention are specifically described below:

[0030] Please combine Figures 1 to 6As shown, the present invention provides a punching loading and unloading device, including a flipping mechanism 2, which includes a blanking assembly and a loading assembly for lifting and placing punched parts, a pick-up and placement table 3, and a transfer mechanism 4; the pick-up and placement table 3 has a completed area 301 for placing punched parts and an unfinished area 302 for placing parts to be punched, which are arranged in sequence along a first direction; the transfer mechanism 4 is arranged between the flipping mechanism 2 and the pick-up and placement table 3 and corresponds to the flipping mechanism 2. The transfer range of the transfer mechanism 4 covers the unfinished area 302, the finished area 301, the blanking assembly, and the loading assembly. The transfer mechanism 4 is used to transfer the punched parts in the unfinished area 302 to be placed on the loading assembly, and at the same time transfer the punched parts on the blanking assembly to the finished area 301. By arranging the finished area 301 and the unfinished area 302 on the pick-up and placement table 3, the flipping mechanism 2 lifts and places the punched parts, and the transfer mechanism 4 is used to transfer the workpieces on the pick-up and placement table 3 and the flipping mechanism 2. By setting a blanking component and a loading component on the flipping mechanism 2, the transfer mechanism 4 places the parts to be punched on the loading component and takes away the punched parts on the blanking component, thereby improving the efficiency of loading and unloading. When the punching machine 6 is punching, the punched parts are transferred and the parts to be punched are prepared at the same time.

[0031] Among them, the flipping mechanism 2 includes a lifting module, and the lifting module includes a mounting seat 204 and a slider 201 movably set on the mounting seat 204. The slider 201 has an extended position and a ready position. The slider 201 moves back and forth between the extended position and the ready position along the second direction. The unloading assembly and the loading assembly are both rotatably set on the slider 201, and the first direction and the second direction are perpendicular. By setting the lifting module, the degree of automation of the punching loading and unloading equipment can be improved. At the same time, the structure is simple and easy to implement. Rotating on the slider 201, it is convenient to adjust the position of the unloading assembly and the loading assembly, and the space occupied is small. In some embodiments, the unloading assembly and the loading assembly can be horizontally movably set on the slider 201. The setting method of the unloading assembly, the loading assembly and the slider 201 can be adjusted according to actual production needs.

[0032] In this embodiment, the lifting module includes a first power member 205, a screw, and a ball nut seat. The slider 201 is connected to the ball nut seat. The first power member 205 is connected to the screw and drives the screw to rotate about its axis. When the screw rotates in the forward or reverse direction, it can drive the ball nut seat to move in the forward or reverse direction along the first direction, thereby achieving reciprocating motion of the slider 201 between the extended position and the ready position. In conjunction with the limiting protrusion and limiting recess, the movement direction of the slider 201 can be limited. At the same time, the screw and ball nut seat are used to control the movement position of the slider 201, converting the rotary motion of the screw into linear motion. This has the characteristics of low friction coefficient, high transmission efficiency, low required transmission torque, high sensitivity, smooth transmission, high tracking accuracy and high positioning accuracy. In this way, when the first pick-and-place assembly 401 and the second pick-and-place assembly 401 pick and place the fixture on the placement table 5, the problem of squeezing the fixture due to low displacement accuracy is avoided, thereby improving the overall stability of the loading and unloading flipping mechanism 2 during operation. The first power member 205 can be a servo motor. The type of the first power member 205 can be adjusted according to actual needs. In some embodiments, the slider 201 can be driven by a cylinder. The method of driving the slider 201 to move can be adjusted according to actual needs.

[0033] Specifically, the loading assembly and the unloading assembly are fixedly connected. The loading assembly has a first lifting position and a material preparation position, while the unloading assembly has a second lifting position and a avoidance position. The loading assembly reciprocates between the first lifting position and the material preparation position, while the unloading assembly reciprocates between the second lifting position and the avoidance position. The first lifting position of the loading assembly and the second lifting position of the unloading assembly overlap, and the avoidance position and the material preparation position are arranged opposite each other. The first lifting position and the second lifting position both correspond to the punching positions of the placement table 5. In this embodiment, the loading assembly and the unloading assembly each include a lifting base plate 207 and an adsorption member disposed on the lifting base plate 207. The extension surfaces of the two lifting base plates 207 are perpendicular to each other and rotate together around the same rotation axis. The two lifting base plates 207 are connected to the above-mentioned rotation axis via a connecting rod 206 perpendicular to the lifting base plates 207. The angle between the connecting rods 206 of the two lifting base plates 207 is 90 degrees. When the loading assembly and the unloading assembly rotate 90 degrees, the first lifting position and the second lifting position coincide. The first lifting position and the second lifting position are both configured to correspond to the placement position of the placement platform 5. The lines connecting the first placement position and the second placement position to the placement position of the placement platform 5 extend along the first direction. In this example, the loading assembly and the unloading assembly are connected to the slider 201 through the rotating module 202. The rotating module 202 includes a transmission member, a transmission belt 208, a driving wheel 209 and a driven wheel 210 connected to the transmission member. The transmission member and the driving wheel 209 are connected to the slider 201. The driven wheel 210 is connected to the rotating shaft and drives the rotating shaft to rotate. The loading assembly and the unloading assembly are both connected to the rotating shaft. The transmission belt 208 is tensioned on the driving wheel 209 and the driven wheel 210. The transmission member is used to drive the driving wheel 209 to rotate, and the driving wheel 209 and the driven wheel 210 are both gears. The transmission belt 208 is a toothed belt. Each gear is engaged with the toothed belt to prevent the transmission belt 208 from slipping during movement, making positioning more accurate.

[0034] The transfer mechanism 4 includes a robotic arm 402 and a pick-and-place assembly 401. The pick-and-place assembly 401 is rotatably mounted on the movable end of the robotic arm 402. The pick-and-place assembly 401 has a first position for unloading materials from the loading assembly at the material preparation position and a second position for unloading materials from the unloading assembly at the material preparation position. The pick-and-place assembly 401 reciprocates between the first and second positions. The rotatable pick-and-place assembly 401 allows different pick-and-place directions to be switched through the movement of the robotic arm 402. In this embodiment, the pick-and-place assembly 401, which is positioned in the first position, rotates 180 degrees to reach the second position, improving the adaptability of the pick-and-place assembly 401. The pick-and-place assembly 401 includes a pick-and-place base plate 404 and a pick-and-place suction cup 405 disposed on the pick-and-place base plate 404. The pick-and-place suction cup 405 is used to pick up and place punched components. One side of the pick-and-place base plate 404 is connected to the movable end of the robotic arm 402, and the other end of the pick-and-place base plate 404 is provided with the pick-and-place suction cup 405. The pick-and-place base plate 404 is provided with weight-reducing holes. The robotic arm is an existing product and will not be described in detail in this application.

[0035] Specifically, the punching loading and unloading equipment further includes a gantry 1 and at least two flipping mechanisms 2. The flipping mechanisms 2 are connected to the gantry 1 via mounting bases 204. The width of the gantry 1 extends along a first direction, and the flipping mechanisms 2 are sequentially arranged along the first direction. By placing the flipping mechanisms 2 on the gantry 1, the transfer mechanism 4 can transfer punched parts and prepare parts to be punched between punching operations of the punching machine 6. This speeds up the loading and unloading of the punching equipment and improves production efficiency.

[0036] Specifically, the transfer mechanism 4 includes a track and a robotic arm 402. The track is arranged along a first direction, and the robotic arm 402 is movably arranged on the track. The track increases the transfer coverage of the robotic arm 402 without increasing the length of the robotic arm 402, and the structure is simple and easy to implement. The robotic arm 402 includes a mounting bracket that engages with the track. The mounting bracket is provided with a travel gear and a travel motor 403 that drives the travel gear. A rack is arranged along the track along the first direction and meshes with the travel gear. When the travel motor 403 drives the gear to rotate, the travel gear meshes with the rack, driving the robotic arm 402 to reciprocate along the first direction. The track comprises two protruding snap-in straight rails along the second direction and two limit rails. Each limit rail has a limit groove extending along the first direction. The limit grooves of the two limit rails are arranged opposite each other. The snap-in base snaps into the limit grooves at both ends along the first direction. The two snap-in straight rails are sequentially arranged between the two limit rails along a third direction, which is perpendicular to both the first and second directions. The snap-in base has a snap-in groove extending along the first direction on the surface where it contacts the snap-in straight rails. The snap-in groove is used to snap into the snap-in straight rails and allows them to move along the snap-in straight rails in the first direction. A rack is provided between the two snap-in straight rails. The track arrangement can be adjusted according to actual needs.

[0037] Specifically, a transfer belt extending along a first direction is provided on each of the finished area 301 and the unfinished area 302 of the pick-up and placement table 3. By providing the transfer belt on the pick-up and placement table 3, punched parts can be moved from the finished area 301 to the next process location, while unpunched parts can be transported one by one to the position where unpunched parts are retrieved by the transfer mechanism 4, thereby improving the automation level of the punching loading and unloading equipment. The transfer belt in the unfinished area 302 moves along the first direction toward the finished area 301, while the transfer belt in the finished area 301 moves along the first direction away from the unfinished area 302. The robot arm 402 can be moved via a track to the separation position between the finished area 301 and the unfinished area 302, thereby placing punched parts while retrieving unpunched parts. This reduces the efficiency of the robot arm 402 in transferring punched parts.

[0038] Among them, both the loading assembly and the unloading assembly include a lifting and placing suction cup 203 for sucking and placing the punching parts and a lifting and placing base plate 207 on which the lifting and placing suction cup 203 is provided, and a weight-reducing structure is provided on the lifting and placing base plate 207. By sucking the punched parts and the unpunched parts by the lifting and placing suction cup 203, damage to the punching parts can be avoided when the punching parts are extracted. In some embodiments, the punching parts can be grasped by the clamping claws. In this embodiment, the robotic arm 402 also sucks the punching parts by the lifting and placing suction cup 203. It should be noted that the lifting and placing suction cup 203 is connected to the vacuum generating device. When the lifting and placing suction cup 203 sucks the punching parts, the vacuum generating device extracts the air in the lifting and placing suction cup 203 to achieve the effect of sucking the punching parts. When the punching parts need to be put down, air can pass through the lifting and placing suction cup 203. This adsorption method is simple and not easy to damage the punching parts, and has a good picking and placing effect.

[0039] The present invention also provides a punching production line, comprising a base, a punching machine 6, a placement table 5, and the punching loading and unloading equipment described above. The punching machine 6 is disposed on the base, and the placement table 5 is movably disposed on the base. The punching machine 6 and the placement table 5 are both disposed corresponding to the flipping mechanism 2 of the punching loading and unloading equipment, and are both disposed on the side of the flipping mechanism 2 away from the pick-up and placement table 3. The placement table 5 has a material change position for transferring punched parts and a punching position for punching. The placement table 5 reciprocates between the material change position and the punching position. When the placement table 5 is in the material change position, the flipping mechanism 2 removes the punched parts and places the unpunched parts. When the placement table 5 is in the punching position, the punching machine 6 punches the unpunched parts.

[0040] The placement table 5 is provided with a placement position for the punching element corresponding to the punching machine 6. The punching position is provided with a pressing element, which is connected to the placement table 5 via a rotary cylinder. When the pressing element presses the punching element, the rotary cylinder drives the pressing element to rotate above the punching element, and then moves along the rotary cylinder's axis toward the placement table 5 to press the punching element. When the pressing element releases the restraint on the pressing element, the pressing element is lifted up by the rotary cylinder, releasing the punching element. The rotary cylinder's axis rotates along its axis, driving the pressing element to move away from the placement position of the placement table 5, so that the pressing element rotates around the rotary cylinder's axis to outside the placement position.

[0041] When the punching production line is working, the placement table 5 is located at the material changing position, that is, it is located below the turning mechanism 2. At this time, there are punched parts placed on the placement table 5, and the pressing part releases the pressure on the punched parts. At this time, there are unpunched parts adsorbed on the loading assembly. The loading assembly is now at the preparation position, that is, the loading assembly is facing the pick-up and placement table 3, and the unloading assembly is facing the placement position of the placement table 5. Driven by the slider 201 of the lifting module, the unloading assembly moves along the second direction toward the placement position of the placement table 5, stops when the slider 201 reaches the extended position, and adsorbs the punched parts on the placement table 5. Driven by the slider 201 of the lifting module, the unloading assembly moves along the second direction toward the placement position of the placement table 5. The loading assembly and the unloading assembly rotate around the same axis, and the loading assembly rotates to the first lifting position, that is, the loading position toward the loading table 5. At this time, the unloading assembly rotates to the avoidance position. Driven by the slider 201, the loading assembly moves along the second direction toward the loading position of the loading table 5, and stops when the slider 201 reaches the extended position. The unpunched parts are placed on the loading table 5, and the pressing part presses the unpunched parts. At the same time, the slider 201 drives the loading assembly away from the loading position of the loading table 5 until the slider 201 reaches the ready position and stops. Through the above steps, one turning mechanism 2 completes a material taking and placing operation. There are multiple turning mechanisms 2 on the gantry 1, and the material taking and placing operations can be completed simultaneously in the above manner. After the loading and placing operation is completed, the loading table 5 moves from the material changing position to the punching machine 6 for the punching process. At this time, the flipping mechanism 2 can first place the unpunched parts on the loading assembly through the robotic arm 402, and remove the punched parts on the unloading assembly, and use the time when the punching machine 6 is punching to transfer the punched parts, which can greatly improve the loading and unloading efficiency of the punching production line.

[0042] In summary, by providing a finished area 301 and an unfinished area 302 on the pick-and-place table 3, the turning mechanism 2 lifts and places the punched workpieces, and the transfer mechanism 4 transfers the workpieces between the pick-and-place table 3 and the turning mechanism 2. By providing a blanking assembly and a loading assembly on the turning mechanism 2, the transfer mechanism 4 places the workpiece to be punched on the loading assembly and removes the punched workpiece from the blanking assembly, thereby improving the efficiency of loading and unloading. While the punching machine 6 is punching, the punched workpieces are transferred and the workpieces to be punched are prepared.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
