Abstract
Description
Technical Field
[0001] This utility model belongs to the field of air-blowing clamping claw technology, and particularly relates to air-blowing clamping claws. Background Technology
[0002] During the production of electronic components, automated equipment is needed to precisely clamp and move components such as resistors, capacitors, and chips. This process runs through key stages such as surface mount technology (SMT) and semiconductor packaging. For example, in SMT, pick-and-place machines use vacuum nozzles or mechanical grippers to pick up smaller components and accurately place them on PCB pads according to programmed coordinates. In chip packaging, high-precision robotic arms need to clamp bare chips to complete bonding or flip-chip bonding, avoiding chip damage due to improper clamping force. At the same time, a vision positioning system calibrates the movement trajectory in real time to ensure the functional stability and reliability of electronic components in the circuit.
[0003] Conventional grippers, due to their complex mechanical transmission structure, struggle to respond quickly during start-up, stopping, and reversing operations when holding electronic components. When gripping electronic components with large cross-sectional areas, grippers with wider spacing are required. However, these wider-spacing grippers are less stable and prone to dropping, potentially damaging the electronic components. Therefore, we propose an air-blown clamping gripper. Utility Model Content
[0004] The purpose of this invention is to provide an air-blowing clamping gripper to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides an air-blowing clamping gripper, comprising:
[0006] An air blowing tube is provided, with a limiting cap fitted at its top end. A sliding groove is provided inside the air blowing tube, and a telescopic rod is slidably installed in the sliding groove. The top end of the telescopic rod passes through the top of the sliding groove and extends to the outside. A fixing nail is inserted into the top end of the telescopic rod. A rotating block is rotatably installed on the fixing nail. A clamping claw is fixedly installed on the top of the rotating block. A top claw is fixedly installed on the top of the telescopic rod, located between the two clamping claws. A movable groove is provided on the rotating block. A sliding rod is slidably installed inside the telescopic rod. A fixing nail is inserted into the sliding rod. One end of the fixing nail passes through the two rotating blocks, and a fixing ring is snapped into one end of the fixing nail.
[0007] A cavity is formed inside the air blowing pipe and located at the bottom of the sliding groove. A push block is slidably installed inside the cavity, and the top end of the push block extends into the sliding groove and is coaxially connected to the sliding rod.
[0008] A buffer assembly, located within a sliding groove, is used to buffer the telescopic rod.
[0009] In this technical solution, during use, the entire device can be moved to insert one end of the top claw and one end of the two clamping claws into the electronic component with holes. During insertion, when the top claw abuts against the electronic component, it will drive the telescopic rod to move. At the same time, the buffer component can cushion the top claw to prevent damage to the electronic component. Subsequently, air can be blown into the air pipe by an air pump. The air will enter the cavity and push the push block to move. The movement of the push block will drive the sliding rod to move. The movement of the sliding rod will squeeze the two rotating blocks to rotate through the fixed pin two. At the same time, the fixed pin two will rotate and move relative to the movable slot. The rotation of the rotating blocks will drive the clamping claws to rotate, so that one end of the two clamping claws moves away from each other. The two clamping claws open to clamp the holes on the electronic component, which can clamp the electronic component from the holes. This ensures that electronic components with large cross-sectional areas can be clamped. Moreover, the clamping response speed can be accelerated by driving the two clamping claws to clamp through the air.
[0010] In the above technical solution, the buffer component further includes:
[0011] A limiting block is fixedly installed at the bottom end of the telescopic rod, and a spring is sleeved on the limiting block and located inside the sliding groove.
[0012] In this technical solution, the movable overall device can insert one end of the top claw and one end of the two clamping claws into the electronic component with holes. At the same time, during the insertion process, when the top claw touches the electronic component, the top claw will drive the telescopic rod to move. The movement of the telescopic rod will compress the spring to retract, which can buffer the top claw and prevent the top claw from damaging the electronic component.
[0013] In the above technical solution, furthermore, the two ends of the spring are tightly welded to the telescopic rod and the bottom of the sliding groove, respectively.
[0014] In this technical solution, the structural stability of the spring is ensured.
[0015] Furthermore, the above technical solution also includes:
[0016] Two fixing rings are respectively snapped onto one end of two fixing nails, and one side of each fixing ring abuts against the rotating block.
[0017] In this technical solution, the two fixing rings and two fixing pins are ensured to limit the movement of the two rotating blocks, preventing them from falling off.
[0018] In the above technical solution, the second fixing nail is movably connected to the movable groove, and one side of the second fixing ring abuts against one of the rotating blocks.
[0019] In this technical solution, it is ensured that the second fixing nail can rotate and slide within the movable groove, and that the second fixing ring can limit the movement of the two rotating blocks and the sliding rod.
[0020] In the above technical solution, furthermore, the periphery of the push block is in close contact with the inner wall of the cavity, and the periphery of the telescopic rod is in close contact with the inner wall of the sliding groove.
[0021] In this technical solution, the airtightness of the cavity and sliding groove is ensured to prevent air leakage during blowing.
[0022] In the above technical solution, the clamping claw is further characterized by an inclined structure, with one side of the clamping claw attached to the top claw, and the top claw having an isosceles trapezoidal structure.
[0023] In this technical solution, the structural stability of the clamping claw and the top claw is ensured.
[0024] The beneficial effects of this utility model are:
[0025] This air-blowing clamping jaw, through the coordinated action of the clamping jaws, top jaws, telescopic rod, buffer assembly, air-blowing pipe, cavity, push block, sliding rod, fixing pin 2, rotating block, and clamping jaws, can clamp electronic components from the hole, ensuring that electronic components with a large cross-sectional area can be clamped. Furthermore, by driving the two clamping jaws with air blowing, the clamping response speed can be accelerated. Attached Figure Description

[0037] Example 1: This example provides an air-blowing clamping gripper, including:
[0038] An air blowing pipe 1 is provided with a limiting cap 2 at its top end. A sliding groove 3 is provided inside the air blowing pipe 1. A telescopic rod 4 is slidably installed inside the sliding groove 3. The top end of the telescopic rod 4 passes through the top of the sliding groove 3 and extends to the outside. A fixing nail 5 is inserted into the top end of the telescopic rod 4. A rotating block 6 is rotatably installed on the fixing nail 5. A clamping claw 7 is fixedly installed on the top of the rotating block 6. A top claw 9 is fixedly installed on the top of the telescopic rod 4 and located between the two clamping claws 7. A movable groove 17 is provided on the rotating block 6. A sliding rod 10 is slidably installed inside the telescopic rod 4. A fixing nail 11 is inserted into the sliding rod 10. One end of the fixing nail 11 passes through the two rotating blocks 6. A fixing ring 12 is snapped into one end of the fixing nail 11.
[0039] Cavity 13 is formed inside the air blowing pipe 1 and located at the bottom of the sliding groove 3. A push block 14 is slidably installed inside the cavity 13. The top end of the push block 14 extends into the sliding groove 3 and is coaxially connected to the sliding rod 10.
[0040] A buffer assembly is located within the sliding groove 3 and is used to buffer the telescopic rod 4.
[0041] In use, the entire device can be moved so that one end of the top claw 9 and one end of each of the two clamping claws 7 can be inserted into the electronic component with the hole. During insertion, when the top claw 9 touches the electronic component, it will move the telescopic rod 4. Simultaneously, the buffer assembly cushions the top claw 9, preventing damage to the electronic component. Then, air can be blown into the air pipe 1 by an air pump. The air enters the cavity 13 and pushes the push block 14 to move. The movement of the push block 14 will move the sliding rod 10. The movement of the 10 mechanism involves the fixed pin 11 pressing against the two rotating blocks 6 to cause them to rotate. Simultaneously, the fixed pin 11 rotates and moves relative to the movable slot 17. The rotation of the rotating blocks 6 causes the clamping claws 7 to rotate, thereby causing one end of the two clamping claws 7 to move away from each other. The opening of one end of the two clamping claws 7 allows them to clamp the holes on the electronic components, ensuring that the electronic components with larger cross-sectional areas can be clamped. Furthermore, the clamping response speed is accelerated by driving the two clamping claws 7 through air blowing.

[0045] The movable device allows one end of the top claw 9 and one end of the two clamping claws 7 to be inserted into the electronic component with holes. During the insertion process, when the top claw 9 touches the electronic component, it will drive the telescopic rod 4 to move. The movement of the telescopic rod 4 will compress the spring 16 to retract, which can buffer the top claw 9 and prevent it from damaging the electronic component.

[0051] Two fixing rings 8 are respectively snapped onto one end of two fixing nails 5, and one side of the fixing ring 8 abuts against the rotating block 6.
[0052] Specifically, the two fixing rings 8 and the two fixing pins 5 are designed to limit the movement of the two rotating blocks 6, ensuring that the two rotating blocks 6 will not fall off.
[0053] Example 5:
[0054] This embodiment provides an air-blowing clamping gripper, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the fixing pin 11 is movably connected to the movable groove 17, and one side of the fixing ring 12 abuts against one of the rotating blocks 6.
[0055] Specifically, it ensures that the second fixing pin 11 can rotate and slide within the movable groove 17, and that the second fixing ring 12 can limit the movement of the two rotating blocks 6 and the sliding rod 10.
[0056] Example 6:
[0057] This embodiment provides an air-blowing clamping gripper, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the periphery of the push block 14 is in close contact with the inner wall of the cavity 13, and the periphery of the telescopic rod 4 is in close contact with the inner wall of the sliding groove 3.
[0058] In particular, ensuring the airtightness of cavity 13 and sliding groove 3 is crucial to prevent air leakage during air blowing.
[0059] Example 7:
[0060] This embodiment provides an air-blowing clamping jaw, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the clamping jaw 7 has an inclined structure, one side of the clamping jaw 7 is attached to the top jaw 9, and the top jaw 9 has an isosceles trapezoidal structure.
[0061] Among them, ensuring the structural stability of the clamping claw 7 and the top claw 9 is crucial.
[0062] Working principle: During use, moving the entire device allows one end of the top claw 9 and one end of each of the two clamping claws 7 to be inserted into the electronic component with the hole. During insertion, when the top claw 9 touches the electronic component, it drives the telescopic rod 4 to move. The movement of the telescopic rod 4 compresses the spring 16, causing it to retract and cushion the top claw 9, preventing damage to the electronic component. Subsequently, air is blown into the air pipe 1 by an air pump. The air enters the cavity 13 and pushes the push block 14 to move. The movement of the push block 14 drives the sliding rod 10 to... As the sliding rod 10 moves, it presses the two rotating blocks 6 together with the fixed pin 11 to rotate. At the same time, the fixed pin 11 rotates and moves relative to the movable groove 17. The rotation of the rotating block 6 drives the clamping claws 7 to rotate, so that one end of the two clamping claws 7 moves away from each other. The opening of one end of the two clamping claws 7 can clamp the holes on the electronic components and can clamp the electronic components from the holes. This ensures that electronic components with larger cross-sectional areas can be clamped. The clamping response speed can be accelerated by driving the two clamping claws 7 to clamp through air blowing.
[0063] Subsequently, the electronic component can be moved. Once it is in the appropriate position, the blowing air is switched to the suction air, which can retract the two gripping claws 7, thereby stopping the gripping of the electronic component. The top claw 9 and the two gripping claws 7 are then removed from the hole. At this time, under the action of the spring 16's rebound force, the spring 16 will squeeze the telescopic rod 4 to reset, ensuring that the secondary use of the telescopic rod 4 is not affected.
