[0050] The following detailed description will further describe the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0053] Some embodiments of the present application will be described in detail below in conjunction with the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0054] Please refer to Figure 1 and Figure 2 An automatic clamp taking and placing device 10 is provided in an embodiment of the present application, which is used for fixing to a machine tool 100. The machine tool 100 is placed with a workpiece 102. The automatic clamp taking and placing device 10 comprises a mounting plate 110 used for connecting with the machine tool 100, a suction mechanism 120 arranged on the mounting plate 110, and a separation mechanism 130. The suction mechanism 120 is used for sucking a clamp 101 and placing the sucked clamp 101 on the workpiece 102. The separation mechanism 130 comprises a movable piece 131 movably arranged on the suction mechanism 120. The movable piece 131 is used for penetrating through the clamp 101 and abutting against the workpiece 102, so as to separate the clamp 101 from the workpiece 102.

[0055] The automatic clamp taking and placing device 10 of the present application realizes the automatic operation of the clamp 101, reduces the time and labor intensity of manual taking and placing, and makes the processing process more efficient. By increasing the separation mechanism 130, when the clamp 101 is sucked, the movable piece 131 can penetrate through the clamp 101 and be placed on the workpiece 102, which can effectively separate the clamp 101 from the workpiece 102. Therefore, the present application solves the problem that the workpiece 102 is lifted and falls when the clamp 101 is taken due to the residual cutting fluid on the workpiece 102, reduces the scratch of the workpiece 102, and improves the yield.

[0056] In an embodiment of the present application, please refer to Figure 2The movable element 131 is provided in two, distributed on the side of the suction mechanism 120. The pressing plate 101 is provided with a positioning hole through which the movable element 131 passes. The movable element 131 can be conveniently placed on the workpiece 102 through the positioning hole, preventing the workpiece 102 from being taken away and falling due to residual cutting fluid.

[0057] In an embodiment of the present application, the separation mechanism 130 further comprises an elastic element 132 and an adjusting column 133. The adjusting column 133 is provided on the suction mechanism 120, and the elastic element 132 is elastically supported on the movable element 131 at one end and on the adjusting column 133 at the other end. The adjusting column 133 is used to adjust the distance between it and the movable element 131, thereby adjusting the elastic force of the elastic element 132 acting on the movable element 131. Considering that the adhesion force between different types of pressing plates 101 and workpieces 102 during separation may differ, the introduction of the elastic element 132 can ensure that the automatic pressing plate taking and placing device 10 can adapt to different adhesion force requirements under various working conditions, avoiding accidental problems caused by excessive adhesion force between the pressing plate 101 and the workpiece 102. Proper adjustment of the elastic force of the elastic element 132 can effectively prevent scratches or damage to the surface of the workpiece 102 during separation, achieving better protection of the workpiece 102. Therefore, through the setting of the elastic element 132, the pressing plate 101 can be more stably controlled during the suction and separation process. Preferably, the elastic element 132 is a compression spring.

[0058] Please refer to Figure 3 In an embodiment of the present application, the separation mechanism 130 further comprises an adjusting seat 134 fixed to the suction mechanism 120. The adjusting column 133 is threadedly connected with the adjusting seat 134. The combination of the adjusting column 133 and the adjusting seat 134 is not only suitable for size changes of different workpieces 102, but also can be individually adjusted according to specific processing needs, so that the automatic pressing plate taking and placing device 10 can flexibly adapt to various application scenarios and meet the needs of different industries. Through threaded connection, the height or position of the adjusting column 133 can be conveniently adjusted, so that the operator can quickly change the distance between the adjusting column 133 and the movable element 131. This design simplifies the adjustment process and reduces the inconvenience that may be caused by manual adjustment. The threaded connection of the adjusting column 133 and the adjusting seat 134 provides a stable fixing method, ensuring that the position of the adjusting column 133 is not easily slipped or loosened during operation, thereby ensuring the stability and consistency of the separation force. After adjustment, the user can use it with confidence without worrying about the problem of accidental displacement of the adjusting column 133 during operation.

[0059] Please refer to Figure 3In an embodiment of the present application, the suction mechanism 120 is provided with a guide groove 1200 accommodating the movable element 131. The guide groove 1200 comprises a first guide portion 1201 and a second guide portion 1202 connected together. The first guide portion 1201 is closer to the mounting plate 110 than the second guide portion 1202, and the width of the first guide portion 1201 is greater than that of the second guide portion 1202. The movable element 131 comprises a support portion 1311 and a separation portion 1312 connected together. The support portion 1311 is movably arranged in the first guide portion 1201 and stopped at the connection between the first guide portion 1201 and the second guide portion 1202, and the separation portion 1312 extends through the second guide portion 1202 and away from the mounting plate 110. The width of the first guide portion 1201 is greater than that of the second guide portion 1202, providing a larger guide surface so that the movable element 131 is more stable when moving, reducing the phenomenon of jamming caused by sliding or deviation. This design can ensure smooth transition of the movable element 131 during pick-and-place operation, avoiding unnecessary failures. The support portion 1311 is stopped at the connection between the first guide portion 1201 and the second guide portion 1202, forming a clear positioning area, which can effectively limit the movement range of the movable element 131, so that it can only move within the designed track. This design ensures accurate positioning and reliability of the movable element 131, avoiding the risk of misoperation or accidental falling. The separation portion 1312 extends through the second guide portion 1202 and away from the mounting plate 110, so that the separation action can be more effectively performed when the pressing plate 101 is picked and placed. This structure provides a clear operation path, which helps the separation mechanism 130 to smoothly operate when interacting with the workpiece 102, increases the stability of movement between the elastic element 132 and the movable element 131, ensures the accuracy of positioning the pressing plate 101, and improves the efficiency of separating the workpiece 102.

[0060] In an embodiment of the present application, the support portion 1311 is provided with a limiting groove 1313 accommodating part of the elastic element 132. The limiting groove 1313 is designed to provide accommodation space for part of the elastic element 132, preventing it from being affected by external impact or displacement during operation. This can effectively protect the elastic element 132, prolong its service life, and ensure its stable performance. The elastic element 132 is limited in the limiting groove 1313, which can avoid slipping and accidental falling during operation, thereby improving the safety of the equipment. By providing the limiting groove 1313 for the elastic element 132 to be placed in, the positioning of the elastic element 132 during assembly is facilitated, and the guiding effect is provided when the elastic element 132 is compressed.

[0061] In an embodiment of the present application, the suction mechanism 120 includes a suction plate 1203 and a magnetic suction assembly 140. The suction plate 1203 is provided with a through slot 1205, and the magnetic suction assembly 140 includes a fixed plate 1401 and at least one electromagnetic suction piece 1402. The fixed plate 1401 is arranged on one side of the through slot 1205, and the electromagnetic suction piece 1402 is fixed to the fixed plate 1401 and accommodated in the through slot 1205.

[0062] Referring to Figure 4 In an embodiment of the present application, the end surface of the electromagnetic suction piece 1402 away from the fixed plate 1401 is flush with the end surface of the suction plate 1203 away from the mounting plate 110. By arranging the end surface of the electromagnetic suction piece 1402 away from the fixed plate 1401 to be flush with the end surface of the suction plate 1203 away from the mounting plate 110, the pressing plate 101 can be effectively taken and placed, so that the pressing plate 101 tightly adheres to the surface of the suction plate 1203.

[0063] Referring to Figure 2 In an embodiment of the present application, the side of the suction mechanism 120 facing the pressing plate 101 is further provided with a proximity switch 160. By arranging the proximity switch 160, the state of taking and placing the pressing plate 101 can be determined, and the degree of automation is improved.

[0064] In an embodiment of the present application, a buffer assembly 150 is further arranged between the mounting plate 110 and the suction mechanism 120. The suction mechanism 120 is provided with a recess 1204. One end of the buffer assembly 150 is placed in the recess 1204, and the other end is connected with the mounting plate 110. The main function of the buffer assembly 150 is to absorb impact and vibration, which can effectively reduce the transmission of vibration generated during operation and protect the equipment and its components from damage. This is particularly important for frequent taking and placing operations, which can greatly reduce wear and tear and prolong the service life of the equipment. By arranging the buffer assembly 150, the connection between the suction mechanism 120 and the mounting plate 110 becomes more stable and flexible. This stability helps to maintain the balance of the device under high speed or severe motion conditions, and improves the accuracy of the overall operation.

[0065] Referring to Figure 2 , Figure 3 and Figure 4In an embodiment of the present application, the buffer assembly 150 comprises a connecting plate 1503, a buffer spring 1501 and a guide 1502. The connecting plate 1503 is fixed to the mounting plate 110. One end of the guide 1502 is fixed to the connecting plate 1503, and the other end of the guide 1502 is movably inserted through the suction mechanism 120. The buffer spring 1501 is sleeved on the guide 1502. One end of the buffer spring 1501 abuts against the groove 1204, and the other end of the buffer spring 1501 abuts against the lower side of the connecting plate 1503. In this way, the suction mechanism 120 is movably connected with the connecting plate 1503, and the connecting plate 1503 is directly mounted on the mounting plate 110 as a base member of the buffer assembly 150, thereby playing a role of connection and support. The connecting plate 1503 can ensure that the entire buffer system is stably fixed on the mounting plate 110, thereby providing a support basis for the operation of the buffer spring 1501 and the guide 1502. The guide 1502 is inserted through the suction plate 1203 and fixedly connected with the connecting plate 1503, thereby playing a role of guidance and fixation. The connecting plate 1503 can ensure that the suction mechanism 120 can move within a certain track during operation, thereby improving the operation accuracy, helping the normal operation of the buffer assembly 150, and preventing unnecessary friction or collision of other components due to displacement. The buffer spring 1501 is sleeved on the guide 1502, one end of the buffer spring 1501 abuts against the groove 1204, and the other end of the buffer spring 1501 abuts against the lower side of the connecting plate 1503. This design allows the buffer spring 1501 to be movably connected between the suction mechanism 120 and the connecting plate 1503, so that the suction mechanism 120 can move freely when subjected to impact or vibration. Through this movable connection, the buffer spring 1501 can effectively absorb and reduce the sudden external force, thereby preventing damage to the equipment.

[0066] Please refer to Figure 1 In an embodiment of the present application, the machine tool 100 comprises the automatic pick-and-place clamp device 10 described above, and the automatic pick-and-place clamp device 10 is fixed to the machine tool 100. The automatic pick-and-place clamp device 10 is fixed to the machine tool 100, thereby realizing seamless integration of the machine tool 100 and the pick-and-place system. This design improves the work efficiency, reduces the coordination time between devices, and improves the overall operation fluency. Thanks to the design of the buffer assembly 150 and the guide 1502, the automatic pick-and-place clamp 101 can maintain high precision during operation, thereby ensuring accurate positioning and processing of the workpiece 102 and reducing the risk of damage to the workpiece 102.

[0067] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application.
