Description

Technical Field

[0001] This utility model provides a material picking and positioning device, and particularly relates to an automatic material picking and high-precision adjustment and positioning device. Background Technology

[0002] In the field of industrial production automation, automatic material handling and high-precision adjustment and positioning devices are used to automatically pick up, move and precisely adjust products on the production line to a designated position to cooperate with subsequent processing and assembly processes. Their core function is to replace manual operation, improve production efficiency, reduce labor costs, and ensure the consistency and accuracy of product processing. They are widely used in manufacturing industries such as electronics, machinery and food.

[0003] Existing automated material handling and high-precision positioning devices typically consist of a simple robotic arm, a manual positioning platform, and scattered control switches. The robotic arm relies heavily on a single suction cup or gripper for material handling, lacking a stable suction structure and prone to product detachment. The positioning platform has low adjustment accuracy, often requiring manual calibration, which is insufficient for high-precision processing requirements. The actions of each stage are controlled independently, lacking a unified control system to coordinate material handling, positioning, and transfer processes, leading to process interruptions. Furthermore, the lack of a product sensing trigger mechanism frequently results in missed or incorrect material handling, and the rudimentary safety measures in the processing area pose operational risks. In the event of a malfunction, the device cannot automatically transfer products, easily causing production stoppages. These shortcomings make it difficult to meet the demands of modern high-precision and high-stability production. Utility Model Content

[0004] In order to solve the above problems, this application provides an automatic material handling and high-precision adjustment and positioning device, which solves the problems of unstable material handling, low positioning accuracy, poor process connection, insufficient safety protection and weak fault response of existing devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic material picking and high-precision adjustment and positioning device, including a production line and a support frame and a material picking robot set next to the production line. The support frame is provided with a waiting area and a positioning area. A preliminary positioning mechanism, a module, a cutting bed, a storage table and a control system are installed on the support frame accordingly.

[0006] The initial positioning mechanism includes an initial positioning platform, a push rod, and a long rod cylinder. The push rod is installed through the material waiting area to push the product into the initial positioning platform. The long rod cylinder is installed below the support frame, and its output end is fixedly connected to a U-shaped connecting rod that is fixedly connected to the push rod. The connecting rod passes through the plate of the material waiting area. The long rod cylinder drives the push rod to move and push the product into the initial positioning platform, making it easier for the module to pick up the product.

[0007] The initial positioning platform has several core positioning components placed on a support frame on the side away from the material waiting area; the core positioning components are located within the activity range of the material handling robot.

[0008] The module is mounted on a guide rail on the top of the support frame and includes a movable seat and a vacuum suction cup. The vacuum suction cup is mounted on the bottom of the movable seat and is used to pick up the product. The cutting bed is located at one end of the module's moving path, and the storage table is located next to the support frame.

[0009] Preferably, the guide rail is equipped with a servo drive device, which is connected to the movable base and drives the module to move back and forth along the guide rail.

[0010] Preferably, a photoelectric sensor is provided at the waiting area, and the photoelectric sensor is electrically connected to the control system to sense the product and trigger the push rod to move.

[0011] Preferably, the control system is used to control the extension and retraction of the push rod and the long rod cylinder, the movement and suction action of the module, the cutting action of the cutting bed, and to control the module to transfer the product to the storage table when the cutting bed fails.

[0012] Preferably, the cutting bed is equipped with a safety light curtain, which is electrically connected to the control system and is used to monitor the safety status of the cutting bed working area.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0014] This automatic material handling and high-precision adjustment positioning device primarily addresses the problems of low automation, insufficient positioning accuracy, disjointed connections between various stages, poor safety, and weak fault response capabilities in existing technologies. It achieves initial positioning by setting up a waiting area and a positioning area on the support frame, using a long-rod cylinder of the initial positioning mechanism to drive a push rod to push the product into the initial positioning platform, and then improving positioning accuracy in conjunction with a core positioning component and a material handling robot. The module's vacuum suction cups, driven by a servo drive device, move along a guide rail to automatically pick up and transfer the product, solving the problem of low efficiency in manual material handling. A photoelectric sensor detects the product and triggers the pushing action, while the control system coordinates the operation of all components to ensure seamless operation. A safety light curtain on the cutting bed ensures operational safety, and in case of malfunction, the module transfers the product to a storage table, improving fault response capabilities and thus comprehensively enhancing automation and production stability.

[0030] like Figure 1 and Figure 2 As shown, the main structure and material handling and positioning components of an automatic material handling and high-precision adjustment positioning device include a production line 1, a support frame 2 set beside the production line 1, and a material handling robot. The support frame 2 is provided with a waiting area 11 and a positioning area 12, and is equipped with a preliminary positioning mechanism 3, a module 4, a cutting bed 5, a storage table 6, and a control system. The preliminary positioning mechanism 3 consists of a preliminary positioning platform 31, a push rod 32, and a long rod cylinder 33. The push rod 32 is installed through the waiting area 11, and the long rod cylinder 33 is installed below the support frame 2. Its output end is fixedly connected to the push rod 32 through the U-shaped connecting rod and the connecting rod passes through the plate of the waiting area 11. The initial positioning table 31 is provided with several glue core positioning parts 7 placed on the support frame 2 on the side away from the waiting area 11, and the glue core positioning parts 7 are located within the activity range of the picking robot. The module 4 is installed on the guide rail 21 on the top of the support frame 2, including a moving seat 41 and a vacuum suction cup 42. The vacuum suction cup 42 is installed at the bottom of the moving seat 41. The cutting bed 5 is set on one side of the end of the moving path of the module 4, and the storage table 6 is set on the side of the support frame 2.

[0031] In this implementation scheme, a support frame 2 and a picking robot are provided beside the production line 1. The waiting area 11 and positioning area 12 on the support frame 2 are respectively installed with components such as the initial positioning mechanism 3. The push rod 32 of the initial positioning mechanism 3 passes through the waiting area 11. The long rod cylinder 33 is connected to the push rod 32 below the support frame 2 through a U-shaped connecting rod. The core positioning component 7 on one side of the initial positioning table 31 is located within the range of motion of the picking robot. The moving seat 41 of the module 4 is mounted on the top guide rail 21 of the support frame 2. The bottom vacuum suction cup 42 is used for material suction. The cutting bed 5 is located at the end of the movement path of the module 4. The storage table 6 is located beside the support frame 2. From the key points of implementation, the long rod cylinder 33 drives the push rod 32 to push the product into the initial positioning table 31, which, together with the core positioning component 7, achieves accurate initial positioning and solves the problem of insufficient positioning accuracy in traditional methods. The module 4 uses the vacuum suction cup 42 to stably suck up the material and moves along the guide rail 21 to complete the transfer, improving the stability and efficiency of material picking. In terms of innovation, the orderly layout of each component on the support frame 2 ensures close connection between the material picking, positioning, and transfer processes. The material picking robot and the core positioning component 7 work together to further improve positioning accuracy, effectively solving the problems of unstable material picking and process disconnection in existing devices, and improving the overall production continuity and accuracy.

[0032] like Figure 3and Figure 4 As shown, the drive, sensing and control related structures of the device include a servo drive device mounted on the guide rail 21. The servo drive device is connected to the moving seat 41 to drive the module 4 to move back and forth along the guide rail 21. A photoelectric sensor 13 is mounted at the material waiting area 11. The photoelectric sensor 13 is electrically connected to the control system. A safety light curtain is mounted on the cutting bed 5. The safety light curtain is electrically connected to the control system. The control system is used to control the extension and retraction of the push rod 32 and the long rod cylinder 33, the movement and suction action of the module 4, the cutting action of the cutting bed 5, and to control the module 4 to transfer the product to the storage table 6 when the cutting bed 5 fails.

[0033] In this implementation scheme, the servo drive device on the guide rail 21 is connected to the moving base 41, which can drive the module 4 to move back and forth along the guide rail 21; the photoelectric sensor 13 at the waiting area 11 is electrically connected to the control system, which can sense the product and transmit signals; the safety light curtain on the cutting bed 5 is electrically connected to the control system, which is used to monitor the safety of the working area; the control system connects to and controls the push rod 32, the long rod cylinder 33, the module 4, the cutting bed 5 and other components respectively. From the implementation points, the servo drive device precisely controls the movement of the module 4, solving the problem of inaccurate positioning of traditional drives; the photoelectric sensor 13 automatically senses and triggers the push action, avoiding the lag of manual intervention; the safety light curtain monitors the cutting bed 5 area in real time to prevent safety accidents. From the innovation point of view, the overall control of the control system realizes the linkage of each link. In case of failure, it can automatically transfer the product to the storage table 6, solving the problem of weak failure response capability of the existing device. The cooperation between the servo drive and the sensing element further improves the automation and intelligence level of the device, ensuring production safety and continuity.

[0034] During use, a vacuum pump from existing technology is required to provide negative pressure to the vacuum suction cup 42. A rotary vane vacuum pump can be used to ensure stable suction. The vacuum suction cup 42 can be made of nitrile rubber to enhance its sealing performance. Power is also required to supply power to the servo drive device, photoelectric sensor 13, etc., through the existing power distribution control cabinet. The power distribution control cabinet is equipped with components such as air switches and contactors. The motor of the servo drive device can be a rare earth permanent magnet synchronous motor to improve the driving accuracy. The long rod cylinder 33 needs to be connected to the existing air source treatment triplet (filter, pressure reducing valve, oil mist lubricator) to ensure a clean and stable air source. The cylinder barrel of the long rod cylinder 33 can be made of 45 steel to enhance its pressure resistance. In addition, the existing industrial Ethernet is required to realize data transmission between the control system and various components. Shielded cables are used to reduce signal interference. These existing technologies work together with this device to ensure the overall high efficiency and stability of operation.

[0035] Specifically, during installation, expansion bolts are used to fix the support frame 2 to the cement floor next to the production line 1. The guide rail 21 is connected to the top flange of the support frame 2 by hexagonal bolts. The motor base of the servo drive device is fixed to the end of the guide rail 21 by positioning pins and bolts. The existing air source device is connected to the long rod cylinder 33 through a PU air pipe. A solenoid valve is installed on the air pipe and controlled by the output signal of the control system. When using it, the air source valve needs to be opened first to adjust the pressure to 0.6-0.8MPa. During operation, after the photoelectric sensor 13 senses the product in the waiting area 11, the long rod cylinder 33 is triggered to extend through the existing PLC programming program, pushing the push rod 32 to send the product into the initial positioning table 31. At the same time, the servo drive device receives pulse signals to drive the module 4 to move. The vacuum suction cup 42 generates negative pressure through the existing vacuum generator to suck up the product. When the safety light curtain of the cutting bed 5 detects foreign objects, it immediately cuts off the power of the cutting bed through the relay and feeds back the signal to the control system, pausing the feeding action of the module 4.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
