Description

Technical Field

[0001] This utility model belongs to the technical field of palletizing devices, specifically a palletizing device for die-cast metal zinc alloy parts. Background Technology

[0002] Zinc alloy die castings are widely used in automotive parts, hardware tools, electronic components and other fields due to their low density, good formability and moderate cost. However, due to their material characteristics (easy to scratch the surface and relatively brittle material) and diverse shapes, in traditional production, zinc alloy die castings mostly rely on manual stacking. Manual operation is not only slow, but also prone to collisions and skewed stacking due to fluctuations in physical strength and non-standard operation, resulting in quality problems such as surface scratches and edge cracks.

[0003] Meanwhile, a palletizing device with announcement number 202322704853.0 is disclosed, including a conveyor table and a fixed plate. The fixed plate is fixedly connected to one side of the conveyor table. An adjustment groove is opened on the top of the fixed plate. A threaded rod is rotatably connected inside the adjustment groove. A moving motor is fixedly connected to the side of the fixed plate away from the conveyor table. The output end of the moving motor passes through one side of the adjustment groove and is fixedly connected to the threaded rod.

[0004] The aforementioned palletizing device lacks specific protective design during use. When gripping, it makes rigid contact through the clamping mechanism, which can easily damage the surface of the workpiece when gripping zinc alloy die-cast parts. Furthermore, the stacking area is generally close to the die-casting machine, where there is a lot of dust. The workpiece is exposed to the air and is easily contaminated by dust. Moreover, the stacked arrangement makes it time-consuming and laborious to remove the workpiece, and there is also a risk of tipping over.

[0005] Therefore, a stacking device for zinc alloy die-cast parts is proposed to address the above problems. Summary of the Invention

[0006] To address the problems mentioned in the background art, this utility model provides a stacking device for zinc alloy die-cast parts. It has the advantages of reducing the contamination of the workpiece surface by external dust and debris during the stacking process through the enclosed space inside the protective box, thus improving the protection of the workpiece. The device also achieves continuous stacking through the set ejection component and the lifting drive component, without the need for manual intervention, thereby reducing downtime.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hardware zinc alloy die-casting parts stacking device, including a base, a placement platform is provided on one side of the top of the base, and a stacking and placement assembly is provided on the other side of the top of the base. The stacking and placement assembly includes a protective box, a support platform, a lifting drive assembly, a support frame, a sliding frame, a storage tray, and an ejection assembly. A robotic arm is provided between the placement platform and the stacking and placement assembly, and a silicone suction cup is connected to the end of the robotic arm.

[0008] Preferably, the protective box is slidably connected to the base via pulleys, the support platform is fixed to one side of the bottom of the protective box, the lifting drive assembly is disposed on the protective box, the lifting drive assembly is connected to the support frame, the support frame is disposed inside the protective box, the sliding frame is equidistantly disposed on the support frame, the storage tray is placed on the sliding frame, and the ejection assembly is installed on one side of the protective box.

[0009] Preferably, the protective box has an opening on the side facing the placement platform, and the support platform is flush with the bottom of the opening.

[0010] Preferably, the lifting drive assembly includes a connecting housing, a lead screw, a first motor, and a lifting sleeve. The connecting housing is fixed to one side of the protective box, the first motor is installed at the top of the connecting housing, the lead screw is disposed inside the connecting housing, and one end of the lead screw is connected to the output shaft of the first motor. The lifting sleeve is connected to the lead screw.

[0011] Preferably, a guide groove is provided at the connection between the connecting housing and the protective box, and the lifting sleeve is fixedly connected to the support frame through the guide groove via a connecting block.

[0012] Preferably, the ejection assembly includes a hydraulic cylinder, an ejection plate, a second motor, and a clamping plate. The hydraulic cylinder is installed on the side of the protective box opposite to the opening. The output end of the hydraulic cylinder is connected to the ejection plate. The second motor is symmetrically arranged at both ends of the ejection plate, and the output shaft of the second motor is connected to the clamping plate.

[0013] Preferably, the sliding frame has a slot on the side facing the top plate that matches the card plate, and the slot has a passage groove for the card plate to pass through vertically.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the setting of a protective box, allows the robotic arm to stack zinc alloy die-cast parts on the placement table onto a storage tray and then collect them into the protective box. The enclosed space inside the protective box can reduce the contamination of the workpiece surface by external dust and debris during the stacking process. Furthermore, the robotic arm can transfer the workpiece using silicone suction cups, which can prevent damage to the workpiece and improve the protection of the workpiece.

[0016] 2. This utility model, through the set ejection component, enables the ejection plate to eject the sliding frame from the protective box. Then, the second motor drives the card plate to rotate, so that the card plate rotates 90 degrees and inserts into the card slot. When the hydraulic cylinder resets, it can pull the sliding frame back into the protective box. With the help of the lifting drive component, continuous stacking can be achieved without manual intervention, reducing downtime. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following describes an embodiment of this utility model based on its overall structure.

[0031] like Figures 1 to 5As shown, this utility model provides a stacking device for zinc alloy die-cast parts, including a base 1, a placement platform 2 on one side of the top of the base 1, and a stacking and placement assembly 3 on the other side of the top of the base 1. The stacking and placement assembly 3 includes a protective box 31, a support platform 32, a lifting drive assembly 33, a support frame 34, a sliding frame 35, a storage tray 36, and an ejection assembly 37. A robotic arm 4 is arranged between the placement platform 2 and the stacking and placement assembly 3. A silicone suction cup 5 is connected to the end of the robotic arm 4. The robotic arm 4 is equipped with a high-definition camera for identifying zinc alloy die-cast parts and adsorbing them. The silicone suction cup 5 is connected to a vacuum pump through an air pipe, and the power of the vacuum pump is dynamically adjusted by a PLC.

[0032] In this embodiment, the protective box 31 is slidably connected to the base 1 via pulleys. The base 1 is provided with a slide rail that matches the pulleys. The pulleys are provided with limiters, which can adjust the position of the protective box 31 and the support platform 32 to facilitate the transfer of workpieces by the robotic arm 4. The support platform 32 is fixed to one side of the bottom of the protective box 31. The lifting drive assembly 33 is provided on the protective box 31 and is connected to the support frame 34. The support frame is provided inside the protective box 31. The sliding frame 35 is equidistantly provided on the support frame 34. The support frame 34 is provided with a positioning boss. The sliding frame 35 is slidably connected to the positioning boss via a slider. The storage tray 36 is placed on the sliding frame 35. The sliding frame 35 is provided with a groove that matches the storage tray 36. The storage tray 36 is provided with a placement slot that matches the zinc alloy die-casting. The ejection assembly 37 is installed on one side of the protective box 31.

[0033] The protective box 31 has an opening on the side facing the placement platform 2, and the support platform 32 is flush with the bottom of the opening. The size of the opening is larger than that of the sliding frame 35.

[0034] The lifting drive assembly 33 includes a connecting housing 331, a lead screw 332, a first motor 333, and a lifting sleeve 334. The connecting housing 331 is fixed to one side of the protective box 31. The first motor 333 is installed at the top of the connecting housing 331. The lead screw 332 is located inside the connecting housing 331, and one end of the lead screw 332 is connected to the output shaft of the first motor 333. The lifting sleeve 334 is connected to the lead screw 332. A guide groove is provided at the connection between the connecting housing 331 and the protective box 31. The lifting sleeve 334 is fixedly connected to the support frame 34 through the guide groove via a connecting block. The first motor 333 of the lifting drive assembly 33 drives the lead screw 332 to rotate, so that the lifting sleeve 334, in conjunction with the connecting block, drives the support frame 34 to rise and fall, adjusting the height of the sliding frame 35 and the storage tray 36 of each layer. With the help of the ejection assembly 37, the workpieces can be stacked continuously in layers.

[0035] The ejection assembly 37 includes a hydraulic cylinder 371, an ejection plate 372, a second motor 373, and a clamping plate 374. The hydraulic cylinder 371 is installed on the side of the protective box 31 opposite to the opening. The output end of the hydraulic cylinder 371 is connected to the ejection plate 372. The second motor 373 is symmetrically arranged at both ends of the ejection plate 372. The output shaft of the second motor 373 is connected to the clamping plate 374. A slot 38 matching the clamping plate 374 is provided on the side of the sliding frame 35 facing the ejection plate 372, and the slot 38 is provided with... The vertical passage slot for the card plate 374 allows the ejector plate 372 to move via the hydraulic cylinder 371 of the ejector assembly 37, so that the ejector plate 372 contacts one end of the sliding frame 35. At this time, the card plate 374 passes through the passage slot of the sliding frame 35. Then, the second motor 373 drives the card plate 374 to rotate, so that the card plate 374 rotates and engages in the card slot 38 to limit the sliding frame 35. This allows the hydraulic cylinder 371, together with the ejector plate 372 and the card plate 374, to push and pull the sliding frame 35, which is convenient and labor-saving.

[0036] The motor, robotic arm, and silicone suction cup are existing technologies and will not be described in detail. Additionally, this invention includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0037] The working principle and process of a zinc alloy die-casting parts stacking device: The zinc alloy die-casting parts to be stacked are placed on the placement platform 2. The mechanical arm 4 drives the silicone suction cup 5 to move, so that the silicone suction cup 5 can pick up the workpiece. Then the mechanical arm 4 rotates to send the workpiece to the storage tray 36 of the stacking and placement component 3. The operation is repeated until the workpiece is filled into the storage tray 36. Then, the hydraulic cylinder 371 of the ejection component 37, together with the clamping plate 374, pulls back the sliding frame 35, so that the storage tray 36 is retracted into the protective box 31. Then the second motor 373 drives the clamping plate 374 to rotate, so that the clamping plate 374 disengages from the clamping slot 38. The hydraulic cylinder 371 drives the ejection plate 372 and the clamping plate 374 to reset. At this time, the first motor 333 of the lifting drive component 33 drives the lead screw 33. 2. Rotation causes the lifting sleeve 334, in conjunction with the connecting block, to lift the support frame 34, which in turn lifts the top storage tray 36. The sliding frame 35 and the storage tray 36 of the next layer are flush with the opening of the protective box 31. The ejector assembly 37 pushes the sliding frame 35 of the next layer out of the protective box 31, so that the sliding frame 35 carries the storage tray 36 onto the support platform 32. The robotic arm 4 arranges the workpieces in layers, and repeated operations achieve continuous stacking without manual intervention, reducing downtime. When the workpieces are put into the protective box 31, the enclosed space inside the protective box 31 reduces the contamination of the workpiece surface by external dust and debris during the stacking process. The robotic arm 4 transfers the workpieces using silicone suction cups 5, which can prevent damage to the workpieces and improve the protection of the workpieces.
