[0060] like Figures 1 to 9 As shown, an end plate punching production line includes a base frame 1, a pick-and-place device 2, a position adjustment device 3, a punching device 4, and a pushing device 5.
[0061] The pick-and-place device 2 is mounted on the base frame 1 and can move left and right along the lateral direction of the base frame 1; the position adjustment device 3 is located on the left side of the base frame 1 and is used to receive and adjust the specific position of the end plate placed by the pick-and-place device 2; the punching device 4 is located on the left side of the position adjustment device 3 and is used to punch through holes on the end plate; the pushing device 5 is located on the left side of the pick-and-place device 2 and moves in response to the pick-and-place device 2, and is used to push the end plate located on the position adjustment device 3 onto the punching device 4.
[0062] The working principle of this application is as follows: When the production line is running, the pick-and-place device 2 moves laterally along the base frame 1 to the end plate stacking area, picks up the end plate and moves it above the position adjustment device 3, and then places the end plate on the position adjustment device 3. Subsequently, the position adjustment device 3 adjusts the position of the received end plate. Then, when the pick-and-place device 2 places the end plate again, the push device 5 pushes the end plate on the position adjustment device 3 to the punching device 4. When the end plate is pushed to the punching station of the punching device 4, the punching device 4 can punch the through holes on the end plate to complete the punching work of the through holes on the end plate.
[0063] This application, through the mechanical linkage design between various devices, ensures smooth process connection and realizes fully automated production of end plate loading, positioning, and punching, effectively improving production efficiency and product quality, reducing enterprise production costs, and helping enterprises achieve intelligent and efficient production goals, thus promoting further enterprise development.
[0064] Furthermore, the pick-and-place device 2 includes a connecting base 21, a movable slide rail 22, a vertically movable pick-and-place assembly 23, a transmission gear rail 24, and a transverse drive assembly 25;
[0065] The connecting seat 21 is located inside the base frame 1; the movable slide rail 22 is slidably connected to the connecting seat 21 along the transverse direction of the connecting seat 21; the vertical moving pick-and-place assembly 23 is located on the left side of the movable slide rail 22 and is used to move the end plate vertically; the transmission gear 24 is located on the upper side of the movable slide rail 22, preferably a helical gear; the transverse drive assembly 25 is located on the upper side of the base frame 1, and its power output end extends downward to mesh with the transmission gear 24, and is used to drive the transmission gear 24 to drive the movable slide rail 22 to move the vertical moving pick-and-place assembly 23 left and right in conjunction with it. Its advantage lies in the sliding connection between the movable slide rail 22 and the connecting seat 21, and the meshing connection between the transverse drive assembly 25 and the transmission gear 24, to achieve stable and precise transverse movement, which in turn facilitates the vertical moving pick-and-place assembly 23 to accurately pick up and place the end plate, and allows the end plate to be smoothly placed on the position adjustment device 3.
[0066] The lateral movement drive group 25 uses a combination of a servo motor and helical gears to ensure that it can mesh with the transmission gear rail 24, and is used to drive the transmission gear rail 24 to drive the moving slide rail 22 to move the up-down moving pick-and-place group 23 left and right in conjunction with it.
[0067] Furthermore, the up-and-down moving pick-and-place group 23 includes a front pick-and-place group 231 and a rear pick-and-place group 232;
[0068] The front pick-and-place assembly 231 is located on the left front side of the movable slide rail 22, and is provided with a front pick-and-place pin 2311 that moves up and down to insert into the hole on the end plate.
[0069] The rear pick-and-place assembly 232 is located on the left rear side of the movable slide rail 22, and is provided with a rear insertion and pick-and-place pin 2321 that moves up and down to insert into the hole on the end plate.
[0070] This application achieves insertion and release of the end plate by cooperating the front insertion and release pin 2311 on the front pick-and-place group 231 with the rear insertion and release pin 2321 on the rear pick-and-place group 232.
[0071] Both the front pick-and-place group 231 and the rear pick-and-place group 232 are driven by drive cylinders, which is convenient to implement.
[0072] Furthermore, the pushing device 5 includes an extension connecting plate 51 and a pushing column 52;
[0073] The extension connecting plate 51 is connected to the movable slide rail 22, located between the front pick-and-place group 231 and the rear pick-and-place group 232, and extends to the left. At least two push-up columns 52 are located on the left side of the extension connecting plate 51 and are spaced apart. The lower end of each push-up column 52 extends downwards onto the lower side of the extension connecting plate 51. This is to achieve a pushing action.
[0074] Furthermore, the position adjustment device 3 includes a connecting frame 31, a vertical movement limiting group 32, a rotating connecting seat 33, a vertical movement insertion group 34, and a push drive group 35;
[0075] The connecting frame 31 has a front guide wheel 311 and a rear guide wheel 312 spaced apart on its upper side, and a left upper clearance opening 313 on its upper left side and a right upper clearance opening 314 on its upper right side. The front guide wheel 311 and the rear guide wheel 312 can be implemented as metal rollers with bearings to guide the end plate to maintain a horizontal posture during lateral movement. The left upper clearance opening 313 and the right upper clearance opening 314 are clearance structures on the connecting frame 31, providing lifting travel space for the vertical movement limiting group 32 and the vertical movement insertion group 34, respectively.
[0076] The vertical movement limiting group 32 is located inside the left side of the connecting frame 31, and can rise upward to extend the upper left clearance opening 313 to limit the end plate.
[0077] The rotating connecting seat 33 is disposed inside the connecting frame 31;
[0078] The vertically movable plug-in assembly 34 is connected to the rotating connecting seat 33, and its upper end is located in the upper right clearance opening 314, which can be raised to plug in the end plate.
[0079] The push drive group 35 is located inside the connecting frame 31, with one end hinged to the up-down moving plug-in group 34 and the other end slidably connected to the connecting frame 31. It is used to push the up-down moving plug-in group 34 to rotate in order to adjust the specific position of the end plate located between the front guide wheel 311 and the rear guide wheel 312.
[0080] This application ensures that the end plate can be horizontally moved into the upper side of the connecting frame 31 by using the front guide wheel 311 and the rear guide wheel 312 on the connecting frame 31. The upper left clearance opening 313 and the upper right clearance opening 314 provide the necessary space for the upper and lower movement limiting group 32 and the upper and lower movement insertion group 34, so that the upper and lower movement limiting group 32 can effectively restrict the end plate from moving to the left, and the upper and lower movement insertion group 34 can be inserted into the end plate through the upper right clearance opening 314. Then, when the drive group 35 pushes the upper and lower movement insertion group 34, the upper and lower movement insertion group 34 rotates under the action of the rotating connecting seat 33, so that the upper and lower movement insertion group 34 can drive the end plate located between the front guide wheel 311 and the rear guide wheel 312 to rotate, thereby realizing the adjustment of the specific position of the end plate.
[0081] Furthermore, the vertical movement limiting assembly 32 includes a lifting limiting cylinder 321 and a limiting guide wheel 322 disposed on the upper end of the lifting limiting cylinder 321. The limiting guide wheel 322 can be implemented as a metal roller with bearings, and its purpose is to rise upwards to limit the leftward displacement of the end plate.
[0082] Furthermore, the upper right clearance opening 314 is arc-shaped;
[0083] The vertically movable plug-in assembly 34 includes a lifting plug-in cylinder 341 connected to the rotating connecting seat 33, a rotating guide wheel 342 located at the upper end of the lifting plug-in cylinder 341 and within the upper right clearance opening 314, and a pin 343 located at the upper end of the lifting plug-in cylinder 341 and in the middle of the rotating guide wheel 342, which can be inserted into an opening on the end plate. This is intended to meet practical usage requirements.
[0084] Furthermore, the position adjustment device 3 also includes a movable auxiliary limiting group 36 located on the upper rear side of the connecting frame 31; the movable auxiliary limiting group 36 includes a connecting crank 361, an auxiliary limiting wheel 362, and an auxiliary limiting drive cylinder 363.
[0085] The connecting crank 361 is hinged to the connecting frame 31 at its middle part; the auxiliary limiting wheel 362 is located on the right end of the connecting crank 361; the left end of the auxiliary limiting drive cylinder 363 is hinged to the connecting frame 31, and its right end is hinged to the left end of the connecting crank 361, for driving the connecting crank 361 to rotate the auxiliary limiting wheel 362 clockwise to contact and limit the end plate located between the front guide wheel 311 and the rear guide wheel 312. Its purpose is to meet the usage requirements of the auxiliary limiting end plate.
[0086] Furthermore, the punching device 4 includes a lower die base 41, an upper die base 42, a lifting guide plate 43, a lifting drive group 44 for the lifting guide plate, a telescopic limit group 45, and a punching drive group (not shown in the figure).
[0087] The lower die base 41 has a punching hole 411; the upper die base 42 is located above the lower die base 41 and has a punching punch 421 that can cooperate with the punching hole 411 to punch through the through hole on the end plate; the lifting guide plate 43 is located between the lower die base 41 and the upper die base 42, with its right end extending to the right to approach the position adjustment device 3 and its left end extending to the left to extend out of the left side of the upper die base 42; the lifting guide plate 43 has a punching hole 411 located on the lower die base 41; The punch 411 has a clearance through hole 431 on its upper side; there are multiple lifting drive groups 44 for the lifting guide plate 43, which are located on the left and right sides of the lifting guide plate 43 and are used to lift the lifting guide plate 43; there are two telescopic limiting groups 45, which are located on the front and rear sides of the lifting guide plate 43 and are used to extend inward to limit the end plate; the punching drive group is located on the upper die base 42 and is preferably a hydraulic device, which is used to drive the upper die base 42 to move downward to match the lower die base 41.
[0088] When the end plate is pushed to the punching station on the lifting guide plate 43, the lifting drive group 44 drives the lifting guide plate 43 to move downward to the working height. At this time, the two sets of telescopic limit groups 45 extend inward to form a physical constraint on the front and rear edges of the end plate. Subsequently, the punching drive group drives the upper die base 42 to move downward. During the downward pressing process, the punching punch 421 passes through the clearance through hole 431 and cooperates with the punching punch 411 to complete the punching operation of the connecting through hole on the end plate. Then, the punching drive group drives the upper die base 42 to move upward, and the lifting drive group 44 drives the lifting guide plate 43 to move the end plate upward, so that the end plate that has completed the punching operation can be pushed to the next station by the next end plate to be punched, thereby achieving continuous conveying and punching operation.
