Description

Technical Field

[0001] This utility model relates to the field of combined diode processing technology, and more specifically, it relates to a combined diode clamping device. Background Technology

[0002] The combined diode gripper is an end effector designed specifically for automated production scenarios. It is mainly used for the safe and efficient handling and inspection of multi-pin semiconductor components such as rectifier bridges and diode arrays. It is a key piece of equipment on modern electronic assembly lines. However, existing combined diode grippers have some drawbacks that affect their daily use.

[0003] The primary problem is that existing diode clamping devices offer only one clamping method. The main types of diode clamping devices are clamping and vacuum adsorption. For clamping, the diode body is brittle and the leads are thin. Hard contact clamping can easily cause lead deformation and body breakage, especially for small-sized or irregularly shaped diodes, where the damage rate is even higher. For vacuum adsorption, oil and dust on the diode surface can damage the seal, causing adsorption and detachment. Airflow fluctuations can also affect positioning accuracy. It is not suitable for diodes with rough surfaces or no flat adsorption surface, and vacuum system failures can directly lead to work interruption.

[0004] More notably, existing diode clamping devices lack circuit detection mechanisms. In automated production, a diode clamping device that only blindly grabs and places components can complete the physical handling, but because it cannot sense the electrical state of the components, it will bring a series of chain reactions and serious negative impacts to the entire production system. The device cannot distinguish whether the component in front of it is a good product or a defective component with an internal open circuit, short circuit, or poor performance. For diodes with circuit problems, the problem can only be discovered after installation, requiring disassembly and replacement, which delays the production schedule.

[0005] Crucially, existing diode clamping devices lack anti-drop mechanisms. When clamping force fluctuates, the adsorption seal fails, or there is vibration during transport, the diodes are prone to falling off, causing the body to crack and the pins to deform, directly rendering them defective. Fallen diodes may get stuck in the device's transmission mechanism or the production line conveyor belt, causing equipment jamming and shutdown. In severe cases, they can wear down core components, forcing the robot to stop immediately and wait for operators or auxiliary equipment to clean up the fallen components and reset them. Re-materials are also required, disrupting the batch operation rhythm and increasing maintenance costs and downtime. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a combined diode clamping device to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a combined diode clamping device, comprising a main board, a fixed leg, and a connecting leg. The main board is fixedly connected to the fixed leg and movably connected to the connecting leg. The main board is fixedly equipped with a first cylinder, and the first cylinder is fixedly equipped with a connecting head. The connecting head is movably equipped with a gripper, which is rotatably connected to the fixed leg and the connecting leg respectively. The main board is fixedly equipped with a vacuum tube, and there is a gap between the vacuum tube and the gripper. The main board is fixedly equipped with a mounting leg, and the mounting leg is fixedly equipped with a second cylinder. The second cylinder is fixedly equipped with a mounting base, and the mounting base is movably equipped with a mounting frame. The mounting frame is fixedly equipped with two placement rings, which respectively engage an output probe and a detection probe. The top of the mounting frame is fixedly equipped with an indicator light, which is connected to the output probe and the detection probe respectively via cables. The fixed leg is fixedly equipped with an anti-drop device.

[0008] The present invention is further configured such that the anti-fall device includes a connecting seat, a servo motor, a connecting rod, and a support rod. The servo motor is fixedly connected to the outside of the fixed leg. The two ends of the connecting rod are fixedly connected to the output shaft of the servo motor and the support rod, respectively. A first detector assembly is fixedly provided at the bottom of the connecting seat, thereby improving the protection against diode drops.

[0009] The present invention is further configured such that a slider is fixedly provided at the top of the connecting leg, the main board is provided with a groove corresponding to the slider, the slider is slidably connected to the groove, the slider is provided with a screw, and the screw is threadedly connected to the slider and the main board respectively, thereby ensuring the normal operation of the adsorption work.

[0010] The present invention is further configured such that the mounting base is provided with an adjustment knob, the adjustment knob is in contact with the mounting bracket and threadedly connected to the mounting base, thereby improving the detection range.

[0011] The present invention is further provided that the bottom end of the gripper is provided with a detachable chuck, and the chuck and the gripper are connected by bolts, thereby reducing the equipment maintenance cost.

[0012] The present invention is further configured such that a second detector assembly is fixedly mounted on the mounting bracket, thereby ensuring the automatic operation of diode circuit detection.

[0013] The present invention is further configured such that a rubber pad is attached to the surface of the support rod, which improves the protection of the diode.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a combined diode clamping device, which has the following advantages: 1. Through the close cooperation between the motherboard, fixed legs, connecting legs, first cylinder, connector, grippers, and vacuum tube, a complete multi-functional fixture is formed. The first cylinder drives the lifting gripper of the connector to pick up and transport components, while the vacuum tube can adsorb and transport diodes. This breaks the limitations of a single mode on the shape and surface of components, enabling multiple uses in one machine. For components with smooth and flat surfaces, vacuum adsorption is used, which is gentle and non-destructive. For irregularly shaped components, components with oil stains, or components that are not easy to adsorb, mechanical clamping is used, which is stable and reliable. This unlocks complex operations that cannot be achieved in a single mode, and can take into account adaptability, stability, and non-destructive protection, meet the needs of multiple operation scenarios, and greatly improve production flexibility and product qualification rate.

[0015] 2. A complete diode circuit testing device is formed by the close cooperation between the second cylinder, mounting base, mounting bracket, placement ring, output probe, detection probe, and indicator light. The second cylinder drives the mounting base to descend, enabling the output probe and detection probe to test the diode circuit. This prevents defective products and faulty parts from flowing into subsequent processes at the source, reduces the number of independent online testing stations, saves production line floor space and equipment investment, records circuit operation data, and can trace the abnormal parameter nodes caused by defective products, providing data support for adjusting the clamping process and adapting to different diode models.

[0016] 3. A complete diode anti-drop device is formed by the tight cooperation between the first detector assembly, servo motor, connecting rod, support rod, and rubber pad. The servo motor is driven to rotate by the first detector assembly, so that the support rod can be suspended below the diode, providing a second layer of protection for the component. Even in the event of a sudden gas outage, power outage, or air pressure fluctuation, the diode will not fall from a height, avoiding the falling component from getting stuck in the precision guide rail, lead screw, or transmission mechanism. This prevents the high maintenance costs and long downtime caused by equipment jamming and motor damage, while also protecting the diode itself. Attached Figure Description

[0022] Please see Figures 1-5 A combined diode clamping device includes a main board 1, a fixed leg 2, and a connecting leg 3. The main board 1 is fixedly connected to the fixed leg 2 and movably connected to the connecting leg 3. The main board 1 is fixedly equipped with a first cylinder 4, and the first cylinder 4 is fixedly equipped with a connector 5. The connector 5 is movably equipped with a gripper 6, which is rotatably connected to the fixed leg 2 and the connecting leg 3 respectively. The main board 1 is fixedly equipped with a vacuum tube 7, and there is a gap between the vacuum tube 7 and the gripper 6. The main board 1 is fixedly equipped with a mounting leg 8, and the mounting leg 8 is fixedly equipped with a second cylinder 9. The second cylinder 9 is fixedly equipped with a mounting base 10, and the mounting base 10 is movably equipped with a mounting frame 11. The mounting frame 11 is fixedly equipped with two placement rings 12, which respectively engage an output probe 13 and a detection probe 14. The top of the mounting frame 11 is fixedly equipped with an indicator light 15, which is connected to the output probe 13 and the detection probe 14 respectively via cables. The fixed leg 2 is fixedly equipped with an anti-drop device.

[0023] In a further embodiment of this application, the anti-fall device includes a connecting seat 16, a servo motor 17, a connecting rod 18, and a support rod 19. The servo motor 17 is fixedly connected to the outside of the fixed leg 2. The two ends of the connecting rod 18 are fixedly connected to the output shaft of the servo motor 17 and the support rod 19, respectively. A first detector assembly 20 is fixedly provided at the bottom of the connecting seat 16. When the main board 1 is raised to move the diode, the first detector assembly 20 detects the height increase and drives the servo motor 17 to rotate, causing the connecting rod 17 to drive the support rod 19 to rotate and move it below the diode. If the diode falls off, it will be caught by the support rod 19 and will not fall to the ground. When the first detector assembly 20 detects the height decrease, it drives the servo motor 17 to flip and move the support rod 19 back to its original position, which facilitates the placement of the diode.

[0024] In a further embodiment of this application, a slider 21 is fixedly provided at the top of the connecting leg 3, and a sliding groove 22 is provided on the main board 1. The slider 21 is slidably connected to the sliding groove 22. The slider 21 is provided with a screw 23, which is threadedly connected to the slider 21 and the main board 1 respectively. If pneumatic adsorption is required, the screw 23 is unscrewed from the main board 1, and the connecting leg 3 is taken out from the sliding groove 22 through the slider 21, so that the connecting leg 3 is removed from the main board 1. Then the gripper 6 is removed to prevent obstruction of the operation of the vacuum tube 7.

[0025] In a further embodiment of this application, the mounting base 10 is provided with an adjustment knob 24. The adjustment knob 24 is in contact with the mounting bracket 11 and threadedly connected to the mounting base 10. Depending on the diode electrode, the adjustment knob 24 can be rotated to allow the mounting base 10 to rotate by an angle. Rotating the adjustment knob 24 again completes the change of the angle of the detection probe 14 and the output probe 13 to adapt to different types of diodes.

[0026] In a further embodiment of this application, the bottom end of the gripper 6 is provided with a detachable chuck 25. The chuck and the gripper 6 are connected by bolts. The chuck 25 can not only increase the gripping range, but also facilitate replacement. The gripper 6 is prone to wear due to frequent contact with the diode, and the gripper 6 is expensive. The chuck 25 can reduce daily maintenance costs.

[0027] In a further embodiment of this application, the mounting bracket 11 is fixedly provided with a second detector assembly 26. After the diode is clamped, the second detector assembly 26 detects that the diode has been clamped and drives the second cylinder 9 to extend, causing the mounting bracket 11 to move down so that the output probe 13 and the detection probe 14 on the placement ring 12 move down and make contact detection with the two ends of the diode electrode.

[0028] In a further embodiment of this application, a rubber pad 27 is attached to the surface of the support rod 19, which can further protect the diode.

[0029] In this embodiment, when the device is used, in the clamping mode, the first cylinder 4 is activated to retract, causing the connector 5 to move upward. The upward movement of the connector 5 causes the gripper 6 to rotate around the fixed leg 2 and the connecting leg 3 to clamp the diode. After clamping, the second detector assembly 26 detects that the diode has been clamped and drives the second cylinder 9 to extend, causing the mounting bracket 11 to move downward, causing the output probe 13 and the detection probe 14 on the placement ring 12 to move downward and contact the two ends of the diode electrode. The output current of the output probe 13 flows back to the detection probe 14 through the diode circuit. If the circuit is normal, the indicator light 15 will light up; otherwise, it will not light up. When the main board 1 is raised to move the diode, the first detector assembly 20 detects the height increase and drives the servo motor 17 to rotate, causing the connecting rod 17 to drive the support rod 19 to rotate and move below the diode. If the diode falls off, it will be caught by the support rod 19 and will not fall to the ground. The rubber pad 27 can further protect the diode.

[0030] More specifically, if pneumatic adsorption is required, screw 23 is unscrewed from the main board 1, and connecting leg 3 is removed from the slide groove 22 via slider 21, so that connecting leg 3 is removed from the main board 1. Then, the clamp 6 is removed, and an external vacuum assembly is connected to the vacuum tube 7. The diode can then be adsorbed by the vacuum tube 7. Then, the second cylinder 9 is moved down to allow the detection probe 14 and output probe 13 to detect the diode. The diode detection and transportation can be completed in the same way. Depending on the diode electrode, the adjustment knob 24 can be rotated to allow the mounting base 10 to rotate. Rotating the adjustment knob 24 again changes the angle of the detection probe 14 and output probe 13. The clamp 25 not only increases the clamping range but also facilitates replacement. The frequent contact between the clamp 6 and the diode can easily cause wear, and the clamp 6 is expensive. The clamp 25 can reduce daily maintenance costs.

[0031] In summary, when the device is in use or operation: When the device is needed and the clamping method is used, the first cylinder 4 is activated to retract, causing the connector 5 to move upward. The upward movement of the connector 5 causes the gripper 6 to rotate around the fixed leg 2 and the connecting leg 3 to clamp the diode. After clamping, the second detector assembly 26 detects that the diode has been clamped and drives the second cylinder 9 to extend, causing the mounting bracket 11 to move downward. This causes the output probe 13 and the detection probe 14 on the placement ring 12 to move downward and contact the two ends of the diode electrode. The output current of the output probe 13 flows back to the detection probe 14 through the diode circuit. If the circuit is normal, the indicator light 15 will light up; otherwise, it will not light up. When the main board 1 is raised to move the diode, the first detector assembly 20 detects the height increase and drives the servo motor 17 to rotate, causing the connecting rod 17 to drive the support rod 19 to rotate and move below the diode. If the diode falls off, it will be caught by the support rod 19 and will not fall to the ground. The rubber pad 27 can further protect the diode.

[0032] If pneumatic adsorption is required, unscrew screw 23 from motherboard 1, remove connecting leg 3 from slide groove 22 via slider 21, remove connecting leg 3 from motherboard 1, remove gripper 6, and connect external vacuum assembly to vacuum tube 7. The diode can then be adsorbed by vacuum tube 7. Then, the second cylinder 9 moves down to allow detection probe 14 and output probe 13 to detect the diode. This can also complete the detection and transportation of the diode. Depending on the diode electrode, the adjustment knob 24 can be rotated to allow mounting base 10 to rotate. Rotating the adjustment knob 24 again changes the angle of detection probe 14 and output probe 13. Gripper 25 not only increases the gripping range but also facilitates replacement. Frequent contact between gripper 6 and diode can easily cause wear and tear, and gripper 6 is expensive. Gripper 25 reduces daily maintenance costs.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
