[0028] Please refer to Figures 1 to 8 For the material taking and clamping device of an embodiment of the utility model, for grabbing circuit board 10, circuit board 10 includes mainboard 11 and installs the subboard 12 of multiple components and parts welding in mainboard 11, material taking and clamping device includes movable assembly 20 and installs the grabbing assembly 30 of movable assembly 20, grabbing assembly 30 includes the first suction 31 for grabbing mainboard 11 of installation in movable assembly 20, and the second suction 32 for grabbing subboard 12 of installation in movable assembly 20, and the surface of second suction 32 and the opposite face of subboard 12 are set with the cooperation of the surface of subboard 12.
[0029] The working principle of the material taking and clamping device of the utility model is as follows: movable assembly 20 drives grabbing assembly 30 to move to the circuit board 10 to be grabbed, so that the first suction 31 is opposite to the mainboard 11 of circuit board 10, and the second suction 32 is opposite to the subboard 12 of circuit board 10; because multiple components and parts are welded on the subboard 12, and the surface of the second suction 32 and the opposite face of the subboard 12 are set with the cooperation of the surface of the subboard 12, the mainboard 11 outside the subboard 12 is adsorbed by the first suction 31, the subboard 12 welded with components and parts is adsorbed by the second suction 32, so that the grabbing assembly 30 grabs the circuit board 10; then the grabbing assembly 30 and the circuit board 10 are transferred to the designated position by the movable mechanism, so that the first suction 31 and the second suction 32 stop working respectively, so that the circuit board 10 is transferred; movable assembly 20 takes the grabbing assembly 30 back to the initial position, waiting for the next time of grabbing.
[0030] Compared with the prior art, the material taking and clamping device of the utility model can grab the mainboard 11 and the subboard 12 respectively by setting the first suction 31 and the second suction 32, meets the grabbing demand of the complex circuit board 10 structure; can accurately grab the corresponding components without damaging the structure of the circuit board 10; by designing the suction surface matched with the surface of the subboard 12, it can be ensured that the subboard 12 is stably and safely grabbed; by driving the first suction 31 and the second suction 32 to move flexibly in space by the movable assembly 20, the grabbing assembly 30 can adapt to various production layouts and circuit board 10 placement conditions.
[0031] Please refer to Figure 3 , Figure 6 and Figure 7The grabbing assembly 30 further comprises a buffer 33 mounted on the movable assembly 20, the buffer 33 comprising a fixed part 330 mounted on the movable assembly 20 and a buffer part mounted on the fixed part 330, the buffer part being arranged towards the mainboard 11. Specifically, the fixed part 330 is provided with a buffer cavity 331, the buffer part comprising a sliding block 332 slidingly arranged in the buffer cavity 331, a spring 333 mounted between the sliding block 332 and the buffer cavity 331, and a rubber block 334 mounted on the free end of the sliding block 332, the rubber block 334 being arranged towards the mainboard 11. When the grabbing assembly 30 approaches the mainboard 11, the rubber block 334 first contacts the mainboard 11; due to the good elasticity and flexibility of the rubber block 334, it will elastically deform under the reaction force of the mainboard 11 at the moment of contact; this deformation can absorb and disperse a small part of the energy generated by the collision, playing a preliminary buffering role and reducing the impact force of the initial collision on the mainboard 11; as the contact pressure continues to increase, the rubber block 334 transmits the force to the sliding block 332; the sliding block 332 starts to slide in the buffer cavity 331, and this sliding structure enables the force to be effectively transmitted to the spring 333; the spring 333 starts to compress under the push of the sliding block 332; as the spring 333 compresses, it absorbs a large amount of collision energy; when the collision force is large, causing the spring 333 to have a large compression amount, the spring 333 can absorb more energy, thereby providing stronger buffering effect. In the whole process, the rubber block 334 and the spring 333 work together; the elastic deformation of the rubber block 334 and the compression deformation of the spring 333 are performed simultaneously, and they jointly convert the kinetic energy generated by the collision into elastic potential energy; the rubber block 334 mainly deals with small-amplitude collisions and initial contact, playing a role of preliminary buffering and uniformly dispersing pressure; the spring 333 mainly plays a buffering role under large impact force, absorbing energy through large-amplitude compression; this layered buffering mode can more effectively cope with collisions of different intensities; in strong collision, the two work together to fully exert their respective buffering performances.
[0032] Please refer to Figure 3 and Figure 5The second suction member 32 comprises a second support part 320 mounted on the movable assembly 20, a second telescopic part 321 mounted on the second support part 320, and a second suction part 322 mounted on the free end of the second telescopic part 321 for suction of the sub-plate 12. The movable assembly 20 moves the grabbing assembly 30 above the position where the sub-plate 12 is located. At this time, the second support part 320 serves as the base part of the second suction member 32, keeping the entire second suction member 32 stably mounted on the movable assembly 20. The second telescopic part 321 is in the initial state, and its length has not changed. The second suction part 322 is at the end of the telescopic part, waiting to contact the sub-plate 12. This structure enables the second suction member 32 to flexibly adapt to sub-plates 12 of different heights and positions. When it is necessary to grab the sub-plate 12, the extension of the second telescopic part 321 enables the second suction part 322 to accurately contact the surface of the sub-plate 12. Since the suction surface of the second suction part 322 cooperates with the surface of the sub-plate 12, it can well conform to the shape of the sub-plate 12 when in contact, providing good contact conditions for subsequent suction operations. After the sub-plate 12 is suctioned, the second telescopic part 321 remains in the extended state to ensure the suction effect between the sub-plate 12 and the second suction part 322.
[0033] The second telescopic part 321 is connected by a plurality of corrugated sections. The plurality of corrugated sections constitute the second telescopic part 321, and each corrugated section has a certain elasticity and foldability. When subjected to external force, the corrugated section can change its shape to realize telescoping. Assuming that the second suction part 322 needs to move downward to approach the sub-plate 12, the axial thrust from the second support part 320 acts on the corrugated section closest to the fixed part 330. This corrugated section begins to extend, which in turn pushes the next corrugated section to extend, and so on, so that the entire second telescopic part 321 is elongated in the axial direction. Conversely, when it is necessary to retract, the corrugated sections will fold under the action of force in the opposite direction to realize retraction.
[0034] Please refer to Figure 3 and Figure 4The first suction member 31 includes a first support part 310 mounted on the movable assembly 20, a first telescopic part 311 mounted on the first support part 310, and a first suction part 312 mounted on the free end of the first telescopic part 311 for suctioning the mainboard 11. The movable assembly 20 will move the entire grabbing assembly 30 to a suitable position above the mainboard 11 according to instructions; the first support part 310 serves as the base part of the first suction member 31, which is used to firmly mount the first suction member 31 on the movable assembly 20 and ensure stability during the entire operation process; the first telescopic part 311 is in the initial state at this time, and its length does not change, and the first suction part 312 is at the end of the telescopic part waiting to contact the mainboard 11; this structure design enables the first suction member 31 to flexibly adapt to mainboards 11 of different heights and positions; when it is necessary to grab the mainboard 11, the first telescopic part 311 starts to work; the extension of the first telescopic part 311 enables the first suction part 312 to accurately contact the surface of the mainboard 11; since the first suction part 312 is designed to suction the mainboard 11, its contact method and contact surface shape will be optimized according to the characteristics of the mainboard 11 to ensure that it can closely fit the mainboard 11 when contacting, thereby creating good conditions for subsequent suction operations.
[0035] The first telescopic part 311 is connected by a plurality of corrugated sections. The first telescopic part 311 is connected by a plurality of corrugated sections, and this structure is similar to a corrugated pipe. Each corrugated section has a certain elasticity and foldability; when it is necessary to be telescopic, the corrugated section will change shape according to the force condition; when the first suction part 312 needs to approach the mainboard 11, the axial thrust from the first support part 310 acts on the corrugated section closest to the fixed part 330; this corrugated section starts to expand under the action of the thrust, and its expansion action will be transmitted to the next corrugated section in turn; just like the bellows of an accordion are pulled open, each corrugated section is unfolded in turn, so that the entire first telescopic part 311 is elongated in the axial direction, thereby enabling the first suction part 312 to smoothly contact the mainboard 11; conversely, when it is necessary to contract the first telescopic part 311, the corrugated sections will fold under the action of force in the opposite direction; for example, after the mainboard 11 is placed in the designated position, the contraction force causes the corrugated sections to gradually recover from the expanded state to the folded state, realizing the contraction of the first telescopic part 311.
[0036] Please refer to Figure 1 and Figure 2The movable assembly 20 comprises a base 21, a first swing arm 22 movably mounted on the base 21, a first driving member (not shown in the figure) mounted on the base 21 for driving the first swing arm 22 to swing, a second swing arm 23 movably mounted on the first swing arm 22, a second driving member (not shown in the figure) mounted on the first swing arm 22 for driving the second swing arm 23 to swing, a rotating arm 24 rotatably mounted on the second swing arm 23, and a rotating driving member (not shown in the figure) mounted on the second swing arm 23 for driving the rotating arm 24 to rotate. The grabbing assembly 30 is mounted on the rotating swing arm. The first driving member is mounted on the base 21 for driving the first swing arm 22 to swing. The first driving member drives the first swing arm 22 to swing around the connecting point between the first swing arm 22 and the base 21, so that the grabbing assembly 30 can approach the target circuit board 10 within a certain range. The second driving member is mounted on the first swing arm 22, which is responsible for driving the second swing arm 23 to swing. The movement of the second swing arm 23 is based on the position of the first swing arm 22. The second swing arm 23 swings around the connecting point between the second swing arm 23 and the first swing arm 22, which further expands the movement range of the grabbing assembly 30. For example, through the coordinated swinging of the first swing arm 22 and the second swing arm 23, the grabbing assembly 30 can cross some obstacles or reach the circuit board 10 located in a complex position. The rotating driving member is mounted on the second swing arm 23 for driving the rotating arm 24 to rotate. The rotating arm 24 is rotatably mounted on the second swing arm 23 through a bearing or other rotating component, and can realize rotation around the shaft. When the rotating driving member works, the rotating arm 24 rotates on the second swing arm 23. This rotating movement can change the angle of the grabbing assembly 30, so that the grabbing assembly 30 can contact the main board 11 and the sub-board 12 of the circuit board 10 at a suitable angle. For example, when the circuit board 10 is placed at different angles or needs to be grabbed from different angles, the rotation of the rotating arm 24 can ensure that the first suction member 31 and the second suction member 32 of the grabbing assembly 30 can accurately fit the target surface. The grabbing assembly 30 is mounted on the rotating arm 24. Through the movement combination of the first swing arm 22, the second swing arm 23 and the rotating arm 24, the grabbing assembly 30 can move and rotate flexibly in three-dimensional space. When the grabbing assembly 30 reaches the appropriate position of the circuit board 10, the first suction member 31 and the second suction member 32 perform the grabbing operation of the main board 11 and the sub-board 12 according to the working principle mentioned above.
[0037] The movable assembly 20 further comprises a fixing frame 25 for mounting the grabbing assembly 30, the grabbing assembly 30 is mounted on the rotating swing arm through the fixing frame 25, and the grabbing assembly 30 further comprises a gas connection pipe 34 mounted on the fixing frame 25. The fixing frame 25 can ensure that the position of the grabbing assembly 30 on the rotating swing arm is accurate and stable; for example, the fixing frame 25 can be precisely matched with the corresponding parts of the grabbing assembly 30 and the rotating swing arm, so that the grabbing assembly 30 always maintains the correct position and posture during rotation and swinging, so as to accurately grab the circuit board 10; when the rotating swing arm moves, various forces and torques in different directions will be generated; the fixing frame 25 can effectively transmit these forces and torques to the grabbing assembly 30; the gas connection pipe 34 is mounted on the fixing frame 25 and is mainly used for transmitting gas; if the first suction member 31 or the second suction member 32 in the grabbing assembly 30 adopts a pneumatic suction mode, one end of the gas connection pipe 34 is connected to the pneumatic component in the grabbing assembly 30, and the other end is connected to an external gas source; when suction operation is needed, compressed air provided by the external gas source enters the corresponding pneumatic component in the grabbing assembly 30 through the gas connection pipe 34; so that the first suction member 31 or the second suction member 32 can suck the circuit board 10.
[0038] The material taking and clamping device further comprises an electromagnetic valve 40 mounted on the second swing arm 23 and a cable storage tube 50 mounted between the base 21 and the second swing arm 23. The electromagnetic valve 40 is mounted on the second swing arm 23 and is a device for controlling the opening and closing of fluid by electromagnetic force; in this device, it is used to control the hydraulic system related to the movement of the movable assembly 20; the electromagnetic valve 40 opens the corresponding channel to make compressed air enter the driving cylinder or hydraulic cylinder to push the piston to move, thereby driving the corresponding swing arm or rotating arm 24 to move; by controlling the opening time and opening degree of the electromagnetic valve 40, the flow of compressed air or hydraulic oil can be accurately adjusted, thereby realizing accurate control of the movement speed, angle, etc. of each component; the cable storage tube 50 is installed between the base 21 and the second swing arm 23, and its main purpose is to protect the internal cables; during the operation of the movable assembly 20, the first swing arm 22, the second swing arm 23 and the rotating arm 24 will move frequently, and if the cables (such as power lines, signal lines, etc.) connected to the base 21 and each component are not protected, they are easy to be damaged by pulling, wear, etc. The cable storage tube 50 can wrap these cables inside to prevent them from being disturbed by external factors; the cable storage tube 50 has a structure that can adapt to the movement of the movable assembly 20; when the second swing arm 23 swings relative to the base 21, the cable storage tube 50 needs to stretch or bend accordingly; so that the cable storage tube 50 can change shape accordingly during the swinging of the second swing arm 23, ensuring that the internal cables are normally connected without being damaged by excessive stretching or bending, and ensuring stable transmission of signals and power.
[0039] The above merely expresses the preferred technical solutions of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these changes and modifications.
