Description

Technical Field

[0001] The invention relates to the technical field of production and processing of detachable feet, and in particular to a detachable foot processing technology and processing equipment. Background Art

[0002] The detachable foot assembly is a furniture component that is easy to disassemble and install, and is mainly used as a supporting structure for furniture such as chairs. The detachable foot assembly usually consists of a center seat and a number of tubular detachable feet that pass through the front and back. The center seat includes a cylindrical fixing sleeve and a number of hollow tubular mounting feet. The detachable foot sleeve is arranged on the other end of the mounting foot and is detachably fixedly connected to the mounting foot. This structure makes the detachable foot easy to disassemble and transport.

[0003] The traditional processing technology of disassembly and assembly feet usually involves manually placing the insert in the mold cavity, then using an injection molding machine to perform injection molding, manually removing the workpiece from the mold after molding, manually cutting off the remaining waste, and finally manually performing the unloading operation.

[0004] The above conventional technical means have a low degree of automation and low production efficiency, especially in the steps of insert placement and workpiece cutting. Frequent manual operations lead to long processing cycles and it is difficult to ensure accurate matching and positioning of the workpiece and insert during the process. Summary of the invention

[0005] In view of this, the present application provides a disassembly foot processing technology and processing equipment to improve production efficiency and reduce processing costs.

[0006] In a first aspect, the present application provides a disassembly foot processing process for processing a workpiece into a disassembly foot, the processing process comprising the following steps: Take the insert: The material taking fixture grabs the insert from the insert feeding station; Taking the workpiece: the injection molding machine drives the injection mold to open the mold, and the material taking fixture extends into the mold to clamp the workpiece and take it out from the mold cavity; Insert placement: the material removal fixture is rotated 180° to place the insert into the mold cavity and fix it; Cutting: The material removal jig places the workpiece into the cutting station, removes the waste material, and processes the workpiece into disassembly feet; Unloading: The material taking fixture places the disassembly foot from the cutting station to the unloading station; Wherein, the material picking fixture clamping the workpiece in the workpiece picking step and the workpiece placing in the material cutting station in the material cutting step are both based on the same positioning.

[0007] By adopting the technical solution of the present application, the disassembly and assembly foot processing technology realizes the automation of the whole process from insert grabbing, workpiece removal, insert placement, waste material cutting to material cutting through the cooperation of the material picking fixture, injection mold and cutting station. The material picking fixture clamps the workpiece and puts the workpiece into the cutting station with reference to the same positioning of the workpiece, which improves the accuracy of the position during the conversion of different stations and improves the shearing quality. Through the precise operation of the material picking fixture, it can be ensured that the insert is accurately placed in the mold cavity, further ensuring the processing quality of the product. This highly automated production method can significantly improve production efficiency, reduce manual intervention, and reduce production costs. The process can adapt to the processing needs of disassembly and assembly feet of different shapes and sizes. It only needs to replace the corresponding injection mold and material picking fixture to realize the production and processing of different products, which has high flexibility. The disassembly and assembly foot processing technology has technical effects such as high degree of automation, high processing accuracy, simple operation, good flexibility, convenient waste treatment and stable product quality, which is of great significance for improving production efficiency, reducing costs and ensuring product quality.

[0008] In some embodiments, the insert taking step includes a feeding step, a dislocation step, a pushing step and a clamping step. In the insert placing step, the insert is placed into the mold cavity in two steps. In the first step, the insert is initially placed in the mold cavity. In the second step, the insert is pushed into the mold cavity by the material taking fixture.

[0009] In some embodiments, the feeding step arranges the inserts in a row in a feeding direction and delivers them to the clamping station, and the dislocation step moves the inserts at the clamping station one by one in a dislocation direction perpendicular to the feeding direction. The inserts are placed in the mold cavity step by step, which improves the stability and accuracy of the insert placement and the quality of the finished product.

[0010] By adopting the above technical solution, the inserts are neatly arranged in a row according to the feeding direction through the feeding mechanism and transported to the clamping station. This ensures the orderly arrangement of the inserts before processing and provides a basis for the automated processing of the subsequent steps. At the same time, the continuity of the feeding step helps to improve the overall processing efficiency. At the clamping station, the inserts are moved one by one in a dislocation direction perpendicular to the feeding direction through the dislocation mechanism. The purpose of this step is to disperse the inserts one by one to ensure that each insert can be clamped independently. It avoids the difficulty or error of clamping caused by the dense arrangement of the inserts, and improves the accuracy and efficiency of clamping. Through the mutual cooperation of the detailed steps such as feeding, dislocation, top feeding and clamping, the inserts can be efficiently and accurately grasped, providing stable and reliable input for the subsequent processing steps. The introduction of these detailed steps not only improves the overall processing efficiency, but also enhances the flexibility and stability of the processing process.

[0011] In some embodiments, in the ejection step, the ejection rod passes through the avoidance hole of the bottom support of the insert, abuts against the bottom surface of the insert, and pushes the insert to move in a height direction perpendicular to the feeding direction and the misalignment direction.

[0012] By adopting the above technical solution, the automation and precise control of the ejection step helps to shorten the transfer time of the insert from the feeding station to the clamping station, thereby improving the overall processing efficiency. In addition, since the movement of the insert in the height direction is perpendicular to the feeding and dislocation directions, it will not interfere with the movement in these two directions, ensuring the continuity and stability of the processing process. By adjusting the position and length of the ejection rod, as well as the shape and size of the avoidance hole, the ejection step can adapt to inserts of different shapes and sizes, which increases the flexibility and versatility of the processing process. Through the ejection step in which the ejection rod passes through the avoidance hole, abuts against the bottom surface of the insert and pushes the insert to move in the height direction, technical effects such as precise control of the insert, avoiding damage, improving processing efficiency, adapting to different insert shapes and sizes, and simplifying the processing process can be achieved. These effects jointly promote the optimization and improvement of the overall processing process.

[0013] In some embodiments, the cutting step also includes a positioning step and a fixing step. The positioning step includes the material picking fixture placing the workpiece in a limiting area of ​​the cutting station to limit the plane movement freedom. After the positioning step, the fixing step limits the height direction freedom of the workpiece.

[0014] By adopting the above technical solution, the positioning step places the workpiece in the limiting area of ​​the cutting station through the material picking fixture, thereby limiting the freedom of movement of the workpiece in the plane (X-axis and Y-axis) direction. This ensures that the workpiece maintains a stable position during the cutting process and avoids cutting errors caused by the movement of the workpiece. The fixing step further limits the freedom of the workpiece in the height direction (Z-axis) to prevent the workpiece from shifting due to vibration or external force during the cutting process, which further improves the accuracy and precision of the cutting. Through the joint action of the positioning step and the fixing step, the position of the workpiece on the cutting station is fully and stably controlled. This helps to reduce the processing failure rate caused by the unstable position of the workpiece and improves the stability and reliability of the overall processing process. By adjusting the shape and size of the limiting area and the fixing device, the positioning step and the fixing step can adapt to workpieces of different shapes and sizes. This increases the flexibility and versatility of the processing process and helps to meet the customized needs of different customers.

[0015] In summary, by adding positioning and fixing steps, the cutting step can achieve comprehensive control of the workpiece in the plane and height directions, improve cutting accuracy and processing stability, and at the same time improve production efficiency and reduce operating difficulty. These effects jointly promote the optimization and improvement of the overall processing process.

[0016] In some embodiments, a transferring step is further included, wherein the transferring step is used to move the shearing table on which the workpiece is placed between a placing position and a shearing position; before the positioning step and the fixing step, the shearing table in the transferring step moves from the shearing position to the placing position, and after the workpiece is placed on the shearing table and the plane movement freedom is limited, the shearing table in the transferring step drives the workpiece to move to the shearing position, where the height direction freedom of the workpiece is limited.

[0017] By adopting the above technical solution, the transfer step allows the shearing table to move between the placement position and the shearing position, which means that the workpiece can be positioned and fixed in one position, and then sheared in another position. This design improves the flexibility of the processing process, so that different steps can be optimized and adjusted in different working areas to adapt to different processing needs. By separating the positioning, fixing and shearing steps in different positions, the entire processing flow can be optimized. For example, the positioning step can be performed in a relatively static environment to ensure the precise placement of the workpiece; while the shearing step can be performed in a more dynamic environment to adapt to the vibration and impact that may be generated during the shearing process. The introduction of the transfer step improves the flexibility of the processing process, optimizes the processing flow, improves the processing efficiency and safety, and adapts to the needs of different workpiece types and sizes. These effects jointly promote the optimization and improvement of the overall processing process, making the processing process more efficient, precise and safe.

[0018] In some embodiments, the method further comprises a pulverizing step, wherein the pulverizing step comprises pulverizing the waste material from the shearing step.

[0019] By adopting the above technical solution, the pulverizing step pulverizes the waste generated in the shearing step so that the waste can be converted into smaller particles or powder. These pulverized wastes can be used as renewable resources to produce other products or reused as raw materials. This helps to reduce resource waste and improve resource utilization. The pulverization process is carried out directly after the shearing step to avoid the accumulation and retention of waste on the production line, thereby keeping the production line smooth and efficient. In addition, the pulverizing step can also be integrated and coordinated with other production steps to achieve a more efficient production and processing process.

[0020] In a second aspect, the present application provides a disassembly foot processing device, which uses the disassembly foot processing process described in the first aspect to process the disassembly foot, and the processing equipment includes a material taking device, a feeding device and a shearing device.

[0021] By adopting the above technical solution, the equipment integrates a material taking device, a feeding device and a shearing device, and can automatically complete the whole process from raw material taking, feeding to shearing processing, thereby greatly improving production efficiency and processing quality. The disassembly foot processing equipment provided by the present application has the advantages of a high degree of automation, precise processing capability, energy-saving and environmental protection, and easy maintenance. It uses the disassembly foot processing technology described in the first aspect to process the disassembly foot, which can improve production efficiency and processing quality, and provide strong technical support for the manufacture of disassembly foot products.

[0022] In some embodiments, the material picking device includes a material picking fixture and a driving mechanism, the material picking fixture includes a workpiece picking fixture and an insert picking fixture, the workpiece picking fixture and the insert picking fixture are arranged back to back and are rotatably connected to the driving mechanism.

[0023] By adopting the above technical solution, the workpiece taking fixture and the insert taking fixture that are arranged opposite to each other can reduce the volume of the material taking device, and the two functions of the workpiece taking fixture and the insert taking fixture are realized by rotating and connecting with the driving mechanism. The corresponding functions are realized by rotating alternately, which is convenient for taking and placing workpieces and inserts in the injection mold. The design of the material taking device not only improves the production efficiency and processing flexibility of the disassembly and assembly foot processing equipment, but also ensures the processing accuracy and reduces the maintenance cost. This design is of great significance for realizing efficient, accurate and automated processing of the disassembly and assembly foot processing equipment.

[0024] In some embodiments, the shearing device includes a shearing table, a shearing assembly, a moving assembly, and a crimping assembly. The shearing table is provided with a positioning column for positioning a workpiece. The moving assembly is connected to the shearing table and drives the shearing table to slide. The crimping assembly is connected to the shearing assembly. When the shearing table slides to the shearing position, the crimping assembly abuts and fixes the workpiece, and the shearing assembly shears the waste workpiece.

[0025] By adopting the above technical solution, the accurate positioning of the workpiece during the shearing process can be ensured through the precise control of the positioning column and the moving assembly on the shearing table. This precise positioning capability is essential to ensure the consistency of shearing quality and appearance. The driving action of the moving assembly enables the shearing table to move the workpiece to the shearing position quickly and smoothly, thereby improving the efficiency of the shearing operation. At the same time, the abutment and fixing action of the crimping assembly can ensure the stability and safety of the shearing process. The design of this shearing device not only improves the shearing efficiency and processing quality of the disassembly and assembly foot processing equipment, but also enhances the flexibility and adaptability of the equipment. At the same time, due to the reasonable connection method and structural design between the various components, the maintenance and maintenance of the equipment also become simpler and more convenient.

[0026] In summary, the present application has at least one of the following beneficial technical effects: 1. The disassembly and assembly foot processing technology of this application has the technical effects of high processing precision, simple operation, good flexibility, convenient waste disposal and stable product quality.

[0027] 2. The disassembly and assembly foot processing equipment of the present application has a high degree of automation and can improve production efficiency and processing quality. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the description of the present application, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0034] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0035] Example 1 See also Figure 1 The disassembly foot processing process provided in the embodiment of the present application includes five steps: taking the insert, taking the workpiece, placing the insert, cutting and unloading, which are specifically as follows: To pick up the insert, the pick-up jig grabs the insert from the insert feeding station. The pick-up jig can be controlled by a multi-joint robot arm to accurately grab the insert. The insert feeding station can arrange the inserts in an orderly manner through a vibrating plate or a spiral conveyor line to facilitate the operation of the pick-up jig. The design of the pick-up jig can be adjusted according to the shape and size of the insert, such as using an electromagnetic chuck, a vacuum chuck or a mechanical gripper. The electromagnetic chuck is suitable for metal inserts, the vacuum chuck is suitable for non-metallic inserts, and the mechanical gripper is suitable for inserts with complex shapes.

[0036] To take the workpiece, the injection molding machine drives the injection mold to open, and the pick-up fixture extends into the mold to clamp the workpiece and remove it from the mold cavity. The mold opening action of the injection molding machine is controlled by a hydraulic cylinder to ensure a smooth and impact-free mold opening process. The gripping part of the pick-up fixture is designed with a soft rubber pad to prevent damage to the workpiece surface. The pick-up fixture can also be equipped with a camera and image recognition system to detect whether the workpiece is clamped correctly, thereby improving production yield.

[0037] Place the insert, and the pick-up fixture takes out the workpiece and rotates 180° to place the insert in the mold cavity and fix it. The rotating mechanism of the pick-up fixture can be a turntable driven by a stepper motor to ensure the accurate rotation angle. The mold cavity can be designed with positioning pins or guide grooves to ensure the accurate position of the insert in the mold.

[0038] Cutting, the material picking fixture puts the workpiece into the cutting station and removes the waste. The cutting station is equipped with a cutter and a cutting platform. The material picking fixture places the workpiece on the cutting platform, and the cutter cuts the waste along a predetermined path. The cutter can be made of high-speed steel or ceramic materials to improve cutting life and accuracy. The cutting platform can be designed with multi-point positioning devices and clamping devices to ensure the stability of the workpiece during the cutting process.

[0039] Unloading, the material picking fixture places the workpiece from the cutting station to the unloading station. The unloading station can be a conveyor belt or a hopper to collect the finished workpieces. The unloading fixture can use a pneumatic or electric pusher during the unloading process to gently place the workpiece at the unloading station to avoid impact on the workpiece.

[0040] The insert taking step includes a feeding step, a dislocation step, a pushing step and a clamping step. In the feeding step, the inserts are arranged in a row in the feeding direction and transported to the clamping station. In the dislocation step, the inserts of the clamping station are moved one by one in a dislocation direction perpendicular to the feeding direction. In the pushing step, the pushing rod passes through the avoidance hole supported at the bottom of the insert and abuts against the bottom surface of the insert and pushes the insert to move in a height direction perpendicular to the feeding direction and the dislocation direction. The cutting step also includes a positioning step and a fixing step. The positioning step includes a material taking fixture placing the workpiece in the limiting area of ​​the cutting station to limit the plane movement freedom. After the positioning step, the fixing step limits the height direction freedom of the workpiece.

[0041] The method further includes a transfer step, which is used to move the shearing table on which the workpiece is placed between the placement position and the shearing position; before the positioning step and the fixing step, the shearing table in the transfer step moves from the shearing position to the placement position, and after the workpiece is placed on the shearing table and the plane movement freedom is limited, the shearing table in the transfer step drives the workpiece to move to the shearing position, where the height direction freedom of the workpiece is limited. The method further includes a crushing step, which includes crushing the waste from the shearing step.

[0042] The implementation principle of this embodiment is as follows: through the above steps, efficient and precise processing of the disassembly and assembly feet is achieved. The insert removal step replaces the traditional manual operation with a multi-joint robot arm, which greatly improves production efficiency and quality stability. In the workpiece removal step, the injection molding machine and the material removal fixture work together to ensure the smooth removal of the workpiece. The insert placement step ensures the accurate position of the insert in the mold through a precise rotating mechanism and mold locating pins. The cutting step reduces the scrap rate through a multi-point positioning device and a high-precision cutter. The unloading step ensures the integrity of the workpiece through a smooth pushing device. The optimization of the entire process has greatly improved the production efficiency of the disassembly and assembly feet, and the product quality has been effectively guaranteed.

[0043] Example 2 The difference between this embodiment and the above-mentioned embodiment is that a pretreatment step of the insert and a precooling step of the workpiece are added, thereby further improving the production efficiency and product quality.

[0044] The step of pretreating the insert is added before the step of taking the insert. The pretreating of the insert may include cleaning, drying and preheating. In the cleaning step, a high-pressure water gun may be used to remove impurities on the surface of the insert. In the drying step, an infrared drying oven may be used to completely remove moisture from the surface of the insert. In the preheating step, an electric heating furnace may be used to preheat the insert to increase the bonding strength between the insert and the plastic. The pretreated inserts may be arranged in order at the insert feeding station, waiting to be grabbed by the material taking fixture.

[0045] Pre-cooling the workpiece: After the workpiece removal step, add a pre-cooling step. The pre-cooling workpiece can be sprayed with ice water or purged with cold air to quickly cool the workpiece and reduce deformation or damage caused by excessive temperature during the subsequent cutting process. The pre-cooling time can be adjusted according to the material and thickness of the workpiece to ensure that the workpiece reaches the appropriate temperature before cutting.

[0046] In the cutting step, the material handling fixture puts the pre-cooled workpiece into the cutting station to remove the waste. The pre-cooled workpiece is not easily deformed during the cutting process, which improves the accuracy and efficiency of cutting. The cutting knife of the cutting station can be made of more wear-resistant materials to extend its service life. The multi-point positioning device and clamping device on the cutting platform can ensure the stability of the workpiece during the cutting process.

[0047] In the unloading step, the pick-up fixture places the workpiece from the cutting station to the unloading station. The unloading station is a conveyor belt with a buffer device, which is used to collect the finished workpieces. During the unloading process, the pick-up fixture uses a pneumatic or electric push device to gently place the workpiece at the unloading station to avoid impact on the workpiece.

[0048] By adding the steps of pre-treating the insert and pre-cooling the workpiece, the production efficiency and product quality of the disassembly feet are further improved. The pre-treating insert step ensures the cleanliness and good bonding performance of the insert through high-pressure water gun cleaning, infrared drying oven drying and electric heating furnace preheating. The pre-cooling workpiece step reduces the deformation of the workpiece during the cutting process by rapidly cooling it down, thereby improving the cutting accuracy. The optimization of the entire process makes the production of disassembly feet more efficient and stable, and the product quality has been significantly improved.

[0049] Example 3 The difference between this embodiment and the above-mentioned embodiment is that an intelligent monitoring system is introduced to monitor the key parameters in the production process in real time, adjust the production parameters in time, and ensure the stability and consistency of the production process.

[0050] Intelligent monitoring system is introduced in each step of taking inserts, taking workpieces, placing inserts, cutting and unloading. The intelligent monitoring system can include photoelectric sensors, data acquisition modules and central controllers. Photoelectric sensors can be installed in key locations such as material picking fixtures, injection molding machines, cutting stations and unloading stations to monitor the gripping status of inserts, the removal status of workpieces, the placement position of inserts, the quality of cutting and the unloading of workpieces in real time. The data acquisition module is responsible for collecting sensor data and transmitting it to the central controller. The central controller dynamically adjusts production parameters based on real-time data, such as the speed of the material picking fixture, the pressure of the injection molding machine, the cutting speed of the cutter, etc., to ensure the stability and consistency of the production process.

[0051] To take the insert, the pick-up fixture grabs the insert from the insert feeding station. The photoelectric sensor of the intelligent monitoring system can detect the arrangement of the insert. If the insert arrangement is abnormal, an alarm will be immediately issued and production will be suspended to prevent defective products from flowing into the next process. The gripping part of the pick-up fixture is designed with a torque sensor, which can monitor the gripping force in real time to ensure that the insert will not be damaged due to over-tight gripping.

[0052] To take the workpiece, the injection molding machine drives the injection mold to open, and the material removal fixture extends into the mold to clamp the workpiece and remove it from the mold cavity. The photoelectric sensor of the intelligent monitoring system can detect the removal status of the workpiece. If it is found that the workpiece cannot be taken out smoothly, it will immediately issue an alarm and adjust the injection molding machine's mold opening speed or the material removal fixture's clamping force to ensure the smooth removal of the workpiece.

[0053] Place the insert, rotate the pick-up fixture 180°, and place the insert into the mold cavity to fix it. The photoelectric sensor of the intelligent monitoring system can detect the placement of the insert. If it is found that the insert is not placed in place, it will immediately sound an alarm and adjust the rotation angle of the pick-up fixture or the position of the locating pin of the mold cavity to ensure the accurate placement of the insert.

[0054] Cutting and picking jigs put the workpiece into the cutting station and remove the waste. The photoelectric sensor of the intelligent monitoring system can detect the quality of the cut material. If the cut material is found to be uneven or has residue, it will immediately sound an alarm and adjust the cutting speed or cutting depth of the cutter to ensure the accuracy of the cut material.

[0055] The unloading and picking fixture places the workpiece from the cutting station to the unloading station. The photoelectric sensor of the intelligent monitoring system can detect the unloading of the workpiece. If it is found that the unloading of the workpiece is not smooth or there is a jam, an alarm will be immediately issued, and the conveyor speed of the unloading station or the pushing force of the picking fixture will be adjusted to ensure the smooth unloading of the workpiece.

[0056] By introducing an intelligent monitoring system, we can monitor the key parameters of the production process in real time and adjust the production parameters in time to ensure the stability and consistency of the production process. The photoelectric sensors of the intelligent monitoring system can detect abnormal conditions in the production process in time and take corresponding measures to avoid the production of defective products, thus improving the reliability and efficiency of production.

[0057] Example 4 See also Figure 2-Figure 11 The present embodiment provides a disassembly foot 6 processing device, which uses the disassembly foot 6 processing process as described in the previous embodiment to process the disassembly foot 6. The processing equipment includes a material removal device 3 for removing the workpiece molded by the injection molding machine 1 from the mold, a feeding device 5 for pushing the insert according to a certain trajectory and direction, and a shearing device 4 for shearing the workpiece. It also includes a cooling line 2 for conveying and cooling the workpiece, and the cooling line 2 uses air cooling to cool the workpiece.

[0058] See also Figure 3-Figure 5 The material picking device 3 includes a material picking fixture 32 and a driving mechanism. The driving mechanism is a mechanical arm 31. The material picking fixture 32 includes a workpiece fixture for clamping the workpiece of the disassembly foot 6 and an insert fixture for clamping the nut 61 in the disassembly foot 6. The workpiece fixture and the insert fixture are arranged opposite to each other and are rotatably connected to the driving mechanism. The mechanical arm 31 is rotatably connected to the material picking fixture 32 through a rotating member 324, and can drive the material picking fixture 32 to rotate along the axis of the rotating member 324 through the rotating member 324. This design enables the material picking fixture 32 to perform material picking and material placing operations on the workpiece and the insert respectively at different positions or directions, thereby improving the flexibility and efficiency of the material picking device 3.

[0059] The robot arm 31 can accurately control the rotation angle and speed of the material picking fixture 32, thereby achieving fast and accurate material picking operations. The modular design of the material picking device 3 allows the material picking fixture 32 to be replaced or upgraded individually, reducing maintenance costs and improving the switching efficiency of material picking fixtures 32 of different specifications. The workpiece picking fixture and the insert picking fixture can be adjusted according to the shape and size of the insert and the workpiece, for example, using an electromagnetic chuck, a vacuum chuck or a mechanical gripper 323. The electromagnetic chuck is suitable for metal inserts, the vacuum chuck is suitable for non-metal inserts, and the mechanical gripper 323 is suitable for inserts with complex shapes.

[0060] See also Figure 4 and Figure 5The material taking fixture 32 of the disassembling foot 6 includes a main body 321, an insert fixture and a workpiece fixture. The insert fixture and the workpiece fixture are arranged on the front and back sides of the main body 321, and a rotating member 324 is arranged on the side of the main body 321. The insert fixture includes a clamp 323 and a first driving member 322 driving the clamp 323 to work, and the workpiece fixture includes a clamp plate 326 and a second driving member 325 driving the clamp plate 326 to work. A control mechanism 327 is arranged in the main body 321 to control the insert fixture and the workpiece fixture to work together. This design allows the insert and the workpiece to be taken and placed on different surfaces (front and back), avoiding the cumbersome steps of replacing the fixture or adjusting the position in the traditional method, thereby greatly improving the operating efficiency. By arranging the insert fixture and the workpiece fixture on the front and back sides of the main body 321 respectively, the fixture maintains functionality while also achieving a compact structure. This design allows the fixture to efficiently handle two different types of components while occupying a small space, thereby improving space utilization. The rotating member 324 disposed on the side of the main body 321 allows the entire fixture to be easily rotated to adapt to different operating requirements or space limitations. This flexibility not only improves the convenience of operation, but also enables the fixture to be used at multiple angles, further expanding its application scenarios.

[0061] The gripping part of the material picking fixture 32 is designed with a soft rubber pad to prevent the surface of the workpiece from being damaged.

This design ensures the stability and safety of the insert in the recess 5221 and avoids the risk of the insert falling off due to insufficient depth during movement. The adapter is connected to an insert sensor 525, which is used to sense whether there is an insert in the recess 5221. This design enables the feeding device 5 to monitor the state of the insert in real time and adjust the feeding action in time, thereby improving the intelligence level and reliability of the system.

[0074] The ejector rod 5241 includes a first column 5242 and a second column 5243 fixedly connected to the first column 5242.
