Description

Technical Field

[0001] This utility model relates to the field of perforated aluminum plate processing technology, and in particular to a blanking mechanism for perforated aluminum plates. Background Technology

[0002] During the processing of perforated aluminum sheets, a punch press, in conjunction with a die, punches and cuts continuous aluminum strips to form perforated aluminum sheets of a specific length (e.g., Figure 8 (As shown). Due to the continuous operation of the punch press, the aluminum strips to be processed constantly push the completed aluminum plates forward, causing them to slip into the side collection frame. This process results in the aluminum plates stacking disorderly within the collection frame, with their edges pressing and deforming against each other. After the punching process is completed, operators must manually tidy up the collection frame to ensure the aluminum plates are stacked neatly before they can be transferred to the next process. Manual tidying not only increases labor intensity, but the sharp edges of the punched aluminum plates can also easily scratch the operators' hands, posing a safety hazard.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a blanking mechanism for perforated aluminum plates, which aims to solve the technical problem of disordered stacking of perforated aluminum plates in the prior art, requiring manual sorting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A blanking mechanism for perforated aluminum sheets includes:

[0007] The frame is located beside the punch press;

[0008] The translation mechanism is mounted on the frame, and its output end is equipped with a moving platform;

[0009] The material frame is detachably mounted on the moving platform. The material frame has several spaced-apart base plates. Each base plate has at least two positioning posts.

The top material frame can pass through the through groove and the clearance hole to lift the movable plate.

[0011] The transfer assembly is mounted on the frame and extends above the punch press table; the actuating end of the transfer assembly is equipped with a pneumatic gripper, which is configured to grip the punched aluminum plate under the drive of the transfer assembly and transfer it to the target movable plate.

[0012] Furthermore, the material frame includes two parallel long side plates and two short side plates connecting the long side plates. The bottom of the long side plates is provided with horizontally extending support bars. Each support bar has several spaced grooves. The end of each bottom plate is respectively embedded in the grooves at corresponding positions of the two support bars.

[0013] Furthermore, the movable plate is provided with several through holes that match the positioning posts, and a positioning groove is opened at the bottom of the movable plate. The top of the top material frame is inserted into the positioning groove to achieve lifting.

[0014] Furthermore, both sides of the movable plate and the base plate are provided with corresponding notches, which are used to expose the edge of the bottom perforated aluminum plate.

[0015] Furthermore, the top of the positioning post is a tapered guide head.

[0016] Furthermore, the translation mechanism includes several guide rails parallel to the frame, a rack parallel to the guide rails, and a first motor on the moving platform; the bottom of the moving platform is provided with a wheel set that is slidably connected to the guide rails, and the output end of the first motor is provided with a gear, which meshes with the rack to drive the moving platform to translate.

To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0034] Please see Figures 1 to 7As shown, this utility model provides a blanking mechanism for perforated aluminum sheets, including: a frame 1, a translation mechanism 2, a material frame 4, a first lifting mechanism 5, and a transfer assembly 7; the frame 1 is located beside the punch press; the translation mechanism 2 is located on the frame 1, and its output end is provided with a moving platform 3; the material frame 4 is detachably installed on the moving platform 3, and the material frame 4 is provided with a plurality of spaced-apart base plates 41; each base plate 41 is provided with at least two positioning posts 42, and a movable plate 43 is slidably connected to the two positioning posts 42. The movable plate 43 is used to stack perforated aluminum sheets, and the perforated aluminum sheets can be inserted into the positioning posts 42. Positioning is achieved; the first lifting mechanism 5 is located below the moving platform 3, and its output end is provided with a top material rack 6; the moving platform 3 is provided with a through groove 31 for avoiding the top material rack 6, and the bottom plate 41 is provided with a clearance hole 411 for avoiding the top material rack 6. The top material rack 6 can pass through the through groove 31 and the clearance hole 411 to lift the movable plate 43; the transfer component 7 is located on the frame 1 and extends above the punching machine worktable; the execution end of the transfer component 7 is provided with a pneumatic gripper 8, which is configured to grip the punched aluminum plate under the drive of the transfer component 7 and transfer it to the target movable plate 43.

[0035] In the above, the position of the punch press worktable is defined as the material picking station, and the position of the first lifting mechanism 5 is defined as the stacking station. Under the drive of the transfer component 7, the pneumatic gripper 8 picks up the punched aluminum plate and transfers it from the material picking station to the stacking station.

[0036] In the initial state, the translation mechanism 2 drives the moving table 3 to translate, so that one of the bottom plates 41 in the material frame 4 is directly above the first lifting mechanism 5. The first lifting mechanism 5 drives the top material rack 6 to rise, passing through the through slot 31 of the moving table 3 and the clearance hole 411 of the bottom plate 41, and lifts the movable plate 43 to the top plane of the positioning post 42, waiting for the perforated aluminum plates to be stacked. When the punching machine completes the punching, and the subsequent aluminum strip pushes the finished product forward, the transfer component 7 drives the pneumatic gripper 8 to move to the material picking station to pick up the perforated aluminum plate, and then transfers it to the stacking station and releases it, so that the perforated aluminum plate falls accurately into the movable plate 43. At the same time, the perforated aluminum plate is inserted into the positioning post 42 to complete the positioning.

[0037] The first lifting mechanism 5 immediately drives the top material rack 6 to descend by the thickness of one aluminum plate, and the movable plate 43 moves down simultaneously to reserve space for the next layer of stacking. This cycle is repeated: the pneumatic gripper 8 picks up, transfers, and positions the material, cooperating with the first lifting mechanism 5 to descend layer by layer until the movable plate 43 moves down to the bottom plate 41, indicating that the single bottom plate 41 has completed the maximum stacking volume. Then, the translation mechanism 2 drives the moving table 3 to translate, so that the adjacent bottom plates 41 are aligned with the stacking station, and a new round of stacking cycle begins. After all the bottom plates 41 are stacked, the operator can directly disassemble the material frame 4 for overall transportation, realizing the function of neatly stacking perforated aluminum plates without manual sorting, improving work efficiency, and avoiding manual contact with the edges and corners of the aluminum plates.

[0038] The aforementioned punch press is an open-type punch press, specifically the JH21-125 open-type punch press. The upper die of the dedicated stamping die is fixed to the punch press slide, while the lower die is mounted on the worktable. The punch press slide reciprocates vertically along the machine guide rail, driving the upper and lower dies to engage and complete the punching and cutting processes on continuously fed aluminum strips, forming individual punched aluminum plates. During the stamping process, the newly formed punched aluminum plate is pushed forward by subsequent aluminum material, and the pneumatic gripper 8 picks up the newly formed punched aluminum plate.

[0039] It should be noted that the translation direction of the moving table 3 is perpendicular to the ejection direction of the perforated aluminum plate; the length direction of the base plate 41 is parallel to the ejection direction of the perforated aluminum plate.

[0040] In the above-described manner, the moving platform 3 is provided with several T-shaped grooves 33 parallel to the direction of the punched aluminum plate being pushed out, and T-shaped nuts are slidably connected within the T-shaped grooves; corner brackets 34 are fixedly installed on each T-shaped nut, and multiple corner brackets 34 together enclose the positioning area of ​​the material frame 4, achieving rapid positioning by constraining the four sides of the bottom surface of the material frame 4. The material frame 4 can be assembled and disassembled by vertically moving upward and downward.

[0041] Optionally, the material frame 4 is provided with several lifting lugs 46 on both sides. During actual transportation, the lifting rope and lifting ring of the lifting equipment are connected to the lifting lugs 46. After being locked by the lifting ring bolts, the fully loaded material frame 4 can be lifted to the designated position as a whole.

[0042] In a preferred embodiment, see [reference] Figure 4 The material frame 4 includes two parallel long side plates 44 and two short side plates 45 connecting the long side plates 44. The bottom of the long side plates 44 has horizontally extending inward support bars 441. Each support bar 441 has several spaced grooves 442. The end of each base plate 41 is respectively embedded in the corresponding grooves 442 of the two support bars 441. The material frame 4 achieves rapid positioning and stable load-bearing of the base plate 41 through the horizontal support bars 441 and their grooves 442 at the bottom of the long side plates 44. During installation, the two ends of the base plate 41 are directly embedded into the corresponding grooves 442 of the two side support bars 441, using the weight of the base plate 41 to achieve horizontal constraint. During disassembly, only the base plate 41 needs to be lifted vertically to detach the entire stacking unit (including the movable plate 43 and the perforated aluminum plate) from the material frame 4, allowing operators to complete the operation by simply lifting vertically when replacing the base plate 41 or transferring the stacked aluminum plates.

[0043] In a preferred embodiment, see [reference] Figure 4 , 5The movable plate 43 is provided with several through holes 431 that match the positioning posts 42. The positioning posts 42 pass through the through holes 431 and maintain a clearance fit, effectively eliminating the horizontal swaying of the movable plate 43 during the lifting process and improving the stability of the movable plate 43's vertical movement. A positioning groove 432 is opened at the bottom of the movable plate 43. The top of the top material frame 6 is inserted into the positioning groove 432 to achieve lifting. The positioning groove 432 limits the position of the top of the top material frame 6, ensuring no deviation during the lifting process and improving stability. When the movable plate 43 moves down to contact the bottom plate 41, the first lifting mechanism 5 continues to drive the top material frame 6 to move down, so that the top of the top material frame 6 automatically disengages from the positioning groove 432, achieving interference-free separation.

[0044] Optionally, the positioning groove 432 is a rectangular groove, and the top material frame 6 is a U-shaped frame. The top of both sides of the U-shaped frame abuts against the inner side walls of the rectangular groove to constrain and eliminate the lateral offset of the top material frame 6.

[0045] Further, see Figure 4 Both the movable plate 43 and the base plate 41 have corresponding notches 412 on both sides, which are used to expose the edges of the bottom layer of perforated aluminum plates. Operators can use a special hook to hook the entire stack of perforated aluminum plates from the notches 412, and with the vertical guidance of the positioning posts 42, the entire stacked unit can be removed. The special hook can be several L-shaped hooks that move in opposite directions, with each hook's hook portion acting on the exposed edge of the perforated aluminum plate. During operation, the multiple L-shaped hooks move synchronously in opposite directions, ensuring the hook portions fully support the bottom edge of the entire stack of perforated aluminum plates, and then the special hooks are moved upwards to complete the removal of a single stack of aluminum plates.

[0046] The aforementioned special hook is not part of the technical solution claimed by this utility model. This embodiment only illustrates the purpose of the notch 412 by demonstrating a special hook and how it lifts a single stack of perforated aluminum plates. In actual use, other tools can be used to act on the exposed edges of the perforated aluminum plates to remove a single stack of perforated aluminum plates.

[0047] In a preferred embodiment, see [reference] Figure 4 The top of the positioning post 42 is a tapered guide head 421. The tapered surface guides the holes in the perforated aluminum plate to be accurately inserted into the positioning post 42, which can overcome the positional deviation during the transfer of the pneumatic gripper 8 and ensure the successful stacking of the perforated aluminum plates.

[0048] In a preferred embodiment, see [reference] Figure 2 , 3The translation mechanism 2 includes several guide rails 21 parallel to the frame 1, racks 22 parallel to the guide rails 21, and a first motor 23 mounted on the moving platform 3. The bottom of the moving platform 3 is provided with a wheel set 32 ​​corresponding to and slidably connected to the guide rails 21. A gear 24 is provided at the output end of the first motor 23. The gear 24 meshes with the rack 22 to drive the moving platform 3 to translate. The wheel set 32 ​​forms a rolling pair constraint with the guide rails 21. The first motor 23 drives the gear 24 to rotate, and the gear 24 meshes with the rack 22 to push the moving platform 3 to translate along the direction of the guide rails 21, thereby transferring the base plates 41 one by one to directly above the first lifting mechanism 5.

[0049] Optionally, the roller assembly 32 contains four rollers to increase the load-bearing capacity of the moving platform 3.

[0050] Optionally, the guide rail 21 has a triangular cross-section, and the rollers in the roller assembly 32 are provided with V-shaped annular grooves that match the guide rail 21. The V-shaped annular grooves cover the guide rail 21 to form a geometric self-locking mechanism, suppressing lateral displacement and overturning moment.

[0051] In a preferred embodiment, see [reference] Figure 6 The first lifting mechanism 5 includes a vertical plate 51 at the bottom of the frame 1, a lifting seat 52 vertically slidably connected to the vertical plate 51, and a second motor 53 on the vertical plate 51. The second motor 53 drives the lifting seat 52 to rise and fall via a ball screw drive pair 54. A top material rack 6 is mounted on the lifting seat 52. The second motor 53 drives the ball screw drive pair 54 via a synchronous pulley assembly 55 to drive the lifting seat 52 to move precisely in a straight line. The top material rack 6 moves synchronously with the lifting seat 52 to adjust the stacking height of the perforated aluminum plates. Compared with a cylinder-driven lifting structure, the total height of the frame 1 is greatly reduced, thereby increasing the upper limit of the stacking height of the perforated aluminum plates. The synchronous pulley assembly 55 and the ball screw drive pair 54 are existing technologies, and their specific structures will not be described in detail.

[0052] In a preferred embodiment, see [reference] Figure 3 , 6 It also includes a first sensor 9, specifically, the first sensor 9 is mounted on the upright plate 51 via a first bracket 91; each base plate 41 has a sensing block 413 at its bottom, and the first sensor 9 is used to detect the position of the sensing block 413. When the translation mechanism 2 drives the moving table 3 to move the material frame 4 forward, the first sensor 9 monitors the position of the sensing block 413 in real time; when the sensing block 413 is detected to enter the detection range of the first sensor 9, it indicates that the next base plate 41 has been precisely moved to the stacking position directly above the first lifting mechanism 5, and the translation mechanism 2 immediately stops moving.

[0053] Optionally, the sensing block 413 and the first sensor 9 adopt Hall effect non-contact detection. The first sensor 9 is a Hall sensor, and the sensing block 413 is a permanent magnet. The Hall sensor can accurately detect the position of the sensing block 413, ensuring seamless connection between the transfer rhythm of the perforated aluminum plate and the switching of the stacking station.

[0054] Further, see Figure 3 , 6 It also includes a second sensor 10 located directly below the notch 412. Specifically, the second sensor 10 is mounted on the upright plate 51 via the second bracket 101. The second sensor 10 is used to detect the height position of the bottom perforated aluminum plate. When the second sensor 10 detects that the perforated aluminum plate has descended to a preset height, it indicates that the movable plate 43 has reached the bottom and the stacking is complete. The first lifting mechanism 5 drives the top material rack 6 to continue to move down until it is completely below the current bottom plate 41. The translation mechanism 2 pushes the moving platform 3 forward. When the first sensor 9 detects the sensing block 413 of the next bottom plate 41 during the forward movement, the translation mechanism 2 stops, the first lifting mechanism 5 drives the top material rack 6 to move up, the movable plate 43 returns to the top of the positioning column 42, and the new stacking cycle restarts.

[0055] Optionally, the second sensor 10 is a proximity switch, which detects the location of the bottom perforated aluminum plate exposed at the edge of the notch 412.

[0056] It should be noted that how the first sensor 9 detects the sensing block 413 and how the second sensor 10 detects the position of the perforated aluminum plate are existing technologies, and their specific working principles will not be elaborated here.

[0057] In a preferred embodiment, see [reference] Figure 7 The transfer assembly 7 includes a gantry frame 71 mounted on the frame 1, a Y-axis linear module 72 mounted on the gantry frame 71 and extending above the punch press worktable, an X-axis linear module 73 located at the output end of the Y-axis linear module 72, and a second lifting mechanism 74 located at the output section of the X-axis linear module 73. A pneumatic gripper 8 is located at the output end of the second lifting mechanism 74. Through the three-axis linkage of the Y-axis linear module 72, the X-axis linear module 73, and the second lifting mechanism 74 (X-axis, Y-axis, and Z-axis), the pneumatic gripper 8 can be precisely positioned in three-dimensional space, flexibly adapting to the handling of punched aluminum plates of different sizes. In practical applications, different material frames 4, base plates 41, positioning posts 42, and movable plates 43 need to be adapted according to different sizes of punched aluminum plates to meet the stacking requirements of different punched aluminum plates.

[0058] Among them, the Y-axis linear module 72 and the X-axis linear module 73 are enclosed ball screw modules, achieving precise linear movement; the first lifting mechanism 5 is a self-guided cylinder drive assembly, specifically a double-rod cylinder, to realize the up-and-down movement of the pneumatic gripper 8. The pneumatic gripper 8 is a pneumatic parallel gripper, and the opening or clamping of the pneumatic parallel gripper realizes the release or gripping of the perforated aluminum plate. Preferably, the pneumatic parallel gripper holds the middle of the perforated aluminum plate to ensure the stability of the gripping.

[0059] In the alternative, the transfer component 7 can be a six-axis collaborative robot to achieve more flexible transfer operations of punched aluminum plates.

[0060] In summary, during the production of perforated aluminum sheets, after the punch press continuously stamps aluminum strips, the newly completed perforated aluminum sheets are pushed out by subsequent aluminum materials. This invention utilizes the pneumatic gripper 8 of the transfer assembly 7, under the three-axis linkage of X, Y, and Z axes, to grab aluminum sheets from the punch press worktable and precisely move them to the stacking station. At this time, the translation mechanism 2 has driven one of the base plates 41 of the material frame 4 to be positioned directly above the first lifting mechanism 5. The top material rack 6 passes through the through slot 31 of the moving table 3 and the clearance hole 411 of the base plate 41, lifting the movable plate 43 to the top of the positioning post 42. After the perforated aluminum sheet is released, it is guided by the conical guide head 421 to accurately insert into the positioning post 42 to complete the hole alignment. The first lifting mechanism 5 drives the top material rack 6 to immediately descend by one plate thickness, and the movable plate 43 simultaneously sinks to reserve space for the next perforated aluminum sheet. This pick-and-place cycle is repeated until the movable plate 43 touches the bottom, completing the stacking of single base plates 41. After the second sensor 10 detects the position of the bottom perforated aluminum plate, the top material rack 6 disengages from the positioning slot 432 and moves downward. The translation mechanism 2 then drives the material frame 4 to switch the adjacent base plate 41 and translate it to the stacking station. The first sensor 9 captures the position of the sensing block 413 of the new base plate 41 in real time and triggers the translation mechanism 2 to stop. The top material rack 6 resets and rises to restart the stacking cycle. After all base plates 41 are fully loaded, the operator uses the lifting lugs 46 of the material frame 4 to transport the entire plate, achieving automated picking and precise stacking of the perforated aluminum plates, which can solve the problems of low efficiency and safety hazards caused by manual intervention.

[0061] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
