Description

Technical Field

[0001] This utility model belongs to the technical field of magnetic die casting equipment, specifically relating to an automatic material handling, weighing, and swivel plate device. Background Technology

[0002] Dimensional and weight errors are unavoidable during the operation of mechanical equipment, and these errors accumulate over time. In molding-related fields, the weight of a product directly affects key parameters such as dimensions and performance. Traditional automated material handling equipment can only use robotic arms and material handling mechanisms to perform simple material handling and placement, without monitoring these critical parameters. Especially in the manufacturing process of NdFeB magnets, pressing NdFeB magnets to produce magnetic properties is a strictly controlled parameter, and these properties are closely related to weight. After products are produced at a rate of 7-12 pieces per minute on a die-casting machine, the traditional method involves manual, periodic quality checks and neat placement of the products on a tray. For lighter products, even minor fluctuations become particularly noticeable. Typically, one worker is needed for every two die-casting machines, increasing production costs and allowing only random sampling, which cannot completely eliminate risks.

[0003] To improve the automation level of NdFeB pressing production, increase production efficiency, and save labor costs, and because weight is particularly important to the magnetic properties of pressed NdFeB products, there is an urgent need to develop an automatic material handling, weighing, and swivel device. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides an automatic material handling, weighing, and tray-loading device, which solves the technical problems of existing equipment lacking integrated material handling, weighing, and discharging functions, as well as the time-consuming, labor-intensive, and inefficient nature of manual inspection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic material handling and weighing tray device includes a base plate, a material tray, and a first support, a second support, a weighing device, and a material tray moving slide rail disposed on the base plate. The first support is connected to a first moving material handling mechanism for picking up products discharged from the die-casting machine onto the weighing device. The second support is connected to a second moving material handling mechanism for picking up weighed products placed on the weighing device onto the material tray.

[0006] Furthermore, the first moving material handling mechanism includes a lateral moving cylinder assembly, a first lifting cylinder, and a first material handling head disposed on the first lifting cylinder. The lateral moving cylinder assembly is disposed at the top of the first support and has a limiting sliding track for the lateral movement of the first lifting cylinder.

[0007] Furthermore, the second moving material handling mechanism includes a servo module, a second lifting cylinder, and a second material handling head disposed on the second lifting cylinder. The servo module is disposed at the top of the second bracket and has a limiting sliding rail for the lateral movement of the second lifting cylinder, thereby controlling the lateral movement of the second lifting cylinder.

[0008] Furthermore, the first and second material-receiving heads are located in the same vertical plane, and the weighing device is disposed between the first and second moving material-receiving mechanisms.

[0009] Furthermore, the weighing device is an electronic scale with signal output and quality detection functions.

[0010] Furthermore, the first material take-up head is located on one side of the die-casting machine's discharge port.

[0011] Furthermore, the material tray is set on the material tray moving slide rail, and a servo motor is also set on the base plate, which drives the material tray to move linearly on the material tray moving slide rail.

[0012] Furthermore, the device also includes a support assembly, on the upper surface of which is provided a second base plate, and on the second base plate is provided a slide rail. The base plate is movably mounted on the slide rail of the second base plate, allowing the position of the device to be adjusted.

[0013] This invention relates to an automated material handling and weighing device developed to improve the automation level of NdFeB product feeding and control product quality during production. The invention creatively adds electronic scales connected to the die-casting machine to both the production and feeding areas. When the product weight deviates from the target set value, the die-casting machine's filling system reacts accordingly, adjusting the powder feeding height to bring the product weight back within the set range.

[0014] This equipment can automatically handle the feeding of pressed products; automatically detect the weight of each product and adjust the powder feeding height through PLC feedback; and automatically and neatly place the products on the drying oven tray at set intervals. This utility model combines feeding, weighing, and tray placement efficiently through a lateral shifting mechanism and two feeding mechanisms; and is connected to the die-casting machine's PLC via an electronic scale to adjust the powder feeding height in real time, as the powder feeding height affects the product weight.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-6 As shown, the present invention provides an automatic material handling and weighing tray device, including a base plate 1, a material tray 2, and a first support 3, a second support 4, a weighing device 5, and a material tray moving slide rail 6 disposed on the base plate 1. The first support 3 is connected to a first moving material handling mechanism for handling the die-casting machine output products onto the weighing device 5. The second support 4 is connected to a second moving material handling mechanism for handling the weighed products placed on the weighing device 5 onto the material tray 2.

[0018] The first moving material handling mechanism includes a transverse moving cylinder assembly 7, a first lifting cylinder 8, and a first material handling head 9 disposed on the first lifting cylinder 8. The transverse moving cylinder assembly 7 is disposed at the top of the first support 3 and has a limiting sliding track for the transverse movement of the first lifting cylinder 8.

[0019] The second moving material handling mechanism includes a servo module 10, a second lifting cylinder 11, and a second material handling head 12 disposed on the second lifting cylinder 11. The servo module 10 is disposed at the top of the second bracket 4 and has a limiting sliding rail for the second lifting cylinder 11 to move laterally, thereby controlling the lateral movement of the second lifting cylinder 11.

[0020] To ensure consistency in material handling, the first material handling head 9 and the second material handling head 12 are positioned in the same vertical plane, and the weighing device 5 is positioned between the first moving material handling mechanism and the second moving material handling mechanism.

[0021] The weighing device 5 is an electronic scale with signal output and quality detection functions.

[0022] The first material handling head 9 is located on one side of the die-casting machine's outlet, and it handles the die-casting machine's output product onto the electronic scale.

[0023] The material tray 2 is mounted on the material tray moving slide rail 6, and a servo motor 13 is also mounted on the base plate 1. The servo motor 13 drives the material tray 2 to move linearly on the material tray moving slide rail 6.

[0024] The automatic material handling and weighing tray device of this utility model also includes a support component 14. A second base plate 15 is provided on the upper surface of the support component 14. A slide rail is provided on the second base plate 15. The base plate 1 is movably mounted on the slide rail of the second base plate 15.

[0025] This utility model uses two shifting mechanisms that are paired with the material picking mechanism. The material picking mechanism is fixed on the slide rail by the limiting sliding rail, and the corresponding first material picking head 9 is controlled to move between the pressing and discharging area and the electronic scale by the transverse moving cylinder assembly 7. At the same time, the second material picking head 12 is controlled to move between the electronic scale and the material tray 2 by the servo module 10.

[0026] The material handling mechanism consists of a lifting cylinder, a limit slide rail, and a material handling suction head. When the material handling mechanism moves to one end of the slide rail via the lateral movement cylinder assembly, the lifting cylinder controls the corresponding material handling head to descend or rise.

[0027] The material handling head of this invention consists of a suction cup connected to a cylinder. During the rising and falling of the material handling head, the cylinder opens and closes to grab or put down the product.

[0028] The material tray 2 is placed on the material tray moving slide rail 6 and is driven by the servo motor 13 to move linearly.

[0029] The electronic scale of this invention was purchased through conventional channels and features signal output and quality detection functions. After the weight is set, it can detect whether the product being weighed is within the range. The signal output device is connected to the powder filling function of the die-casting machine; if the weight exceeds the set range, the die-casting machine automatically adjusts the powder filling height.

[0030] The automatic material handling, weighing, and tray-loading device of this utility model has the following specific working steps: (1) After the die-casting machine presses out the product, the first picking head 9 moves to the discharge area through the transverse moving cylinder assembly 7. The first picking head 9 descends under the action of the first lifting cylinder 8 to pick up the product; (at this time, the second picking head moves synchronously without load) (2) The first picking head 9 moves the picked-up product to the electronic scale position through the transverse moving cylinder assembly 7, the first picking head 9 lowers to release the product, and the electronic scale weighs the product. Then the first picking head 9 moves in the opposite direction to return to the initial state; (3) In sync with steps (1) and (2), the second pick-up head 12 moves from the electronic scale position to the predetermined position of the material tray via the servo module 10 (the qualified and unqualified products are placed at different predetermined positions on the material tray respectively), the pick-up head descends, picks up the product, moves to the material tray position and puts the product down.

[0031] (4) When a defective product appears, the electronic scale sends a signal to the die-casting machine PLC to adjust the powder filling height of the next product.

[0032] This utility model equipment is mainly developed for pressing NdFeB products and other magnetic powder pressing products. Other products in the field of powder forming (ferrite, powder alloy, ceramics, etc.) may also use similar logic and systems. After simple modification, they can all be used for picking up and putting down materials and quality control of specific products.

[0033] It should be noted that the specific implementation and detailed structure of the relevant mobile control mechanism of this utility model are all existing technologies and will not be described in detail here. In addition, the first and second picking heads of this application move synchronously. Except for the first product discharged from the die-casting machine (the first picking head picks up and puts up the first product, and the second picking head is unloaded), the first picking head moves the discharged product to the electronic scale and then returns to the initial position to pick up the next product. The synchronous second picking head picks up the weighed product and places it on the predetermined position of the tray. After the tray is full, the servo motor controls the tray to move and make room for a new product placement area, and so on.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
