[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1

[0027] This embodiment provides an electromagnetic gripper mechanism, such as... Figure 1 Combination Figure 2 As shown, the device includes a main body 1, clamping arms 2, a first electromagnet 3, and a second electromagnet 4. The clamping arms 2 are provided with magnetic attraction areas, and the two clamping arms 2 are disposed opposite to each other on the main body 1. The clamping arms 2 are slidably connected to the main body 1. The first electromagnet 3 is disposed on the side of the main body 1 near the clamping arms 2, and is located between the two clamping arms 2. The first electromagnet 3 is used to bring the two magnetic attraction areas closer together. The second electromagnet 4 is disposed on the side of the main body 1 near the clamping arms 2, and the two second electromagnets 4 are respectively located on the sides of the two clamping arms 2 away from each other. The second electromagnet 4 is used to keep the two magnetic attraction areas away from each other.

[0028] For example, during implementation, the clamping arm 2 is slidably connected to the main body 1. For instance, a mounting groove is formed at one end of the main body 1, a guide rail is installed in the mounting groove, and the two ends of the guide rail are respectively connected to two opposite groove walls of the mounting groove. At the same time, a sliding groove is formed at one end of the clamping arm 2, and the clamping arm 2 is slidably connected to the guide rail of the main body 1 through the sliding groove, thereby achieving the purpose of slidably connecting the clamping arm 2 to the main body 1.

[0029] The clamping arm 2 is provided with a magnetic attraction area. For example, at one end of the clamping arm 2 near the main body 1, a structure that can be attracted by an electromagnet, such as an iron block or a permanent magnet, is installed by means of screwing, fitting, or other methods, so that the structure that can be attracted by an electromagnet, such as an iron block or a permanent magnet, can form a magnetic attraction area on the clamping arm 2. There are two clamping arms 2, which are arranged opposite to each other on the main body 1.

[0030] The first electromagnet 3 is installed on the side of the main body 1 near the clamping arm 2 by means of screwing, snapping, or other methods. The first electromagnet 3 is located between the two clamping arms 2. When the first electromagnet 3 is energized, it generates a magnetic field, which simultaneously attracts the two magnetic attraction areas to itself (the first electromagnet 3), thereby causing the two clamping arms 2 to move closer to each other, so as to achieve the purpose of clamping the workpiece by the two clamping arms 2.

[0031] The second electromagnet 4 is installed on the side of the main body 1 near the clamping arm 2 by means of screwing, snap-fit, or other methods. There are two second electromagnets 4: one is located on the side of one clamping arm 2 away from the other, and the other is located on the side of the other clamping arm 2 away from the first clamping arm 2. When both second electromagnets 4 are energized, they generate magnetic fields. Each second electromagnet 4 attracts its corresponding magnetic attraction area (the magnetic attraction area closest to it) towards itself, thereby causing the two clamping arms 2 to move away from each other, thus releasing the workpiece between the two clamping arms 2.

[0032] During operation, when a workpiece needs to be clamped, the first electromagnet 3 is energized while the second electromagnet 4 is de-energized. At this time, the first electromagnet 3 generates a magnetic field, simultaneously attracting two magnetic attraction areas towards itself (the first electromagnet 3), which in turn causes the two clamping arms 2 to move closer together to hold the workpiece. When the workpiece needs to be released, the two second electromagnets 4 are energized while the first electromagnet 3 is de-energized. At this time, the two second electromagnets 4 generate magnetic fields, attracting corresponding magnetic attraction areas (the magnetic attraction areas closest to the second electromagnet 4) towards themselves (the second electromagnet 4), which in turn causes the two clamping arms 2 to move away from each other to release the workpiece. In this embodiment, the electromagnetic gripper mechanism achieves clamping or releasing through simultaneous action from both sides. Compared to traditional single-sided electromagnetic grippers, the clamping and releasing speeds of this embodiment are faster, resulting in higher gripping efficiency. Simultaneously, it effectively reduces the risk of workpiece slippage caused by uneven force on one side.

[0033] Example 2

[0034] Based on the above embodiment 1, in this embodiment, as follows: Figure 1As shown, the electromagnetic gripper mechanism further includes an adjustment knob 5; the knob is disposed on the main body 1, and the adjustment knob 5 is connected to the first electromagnet 3; wherein, the adjustment knob 5 is used to adjust the electromagnetic force of the first electromagnet 3.

[0035] For example, in the implementation process, the electromagnetic gripper mechanism also includes an adjustment knob 5. The adjustment knob 5 is installed on the main body 1 by means of screwing, snapping or other methods, and the adjustment knob 5 is connected to the first electromagnet 3 by a wire.

[0036] During use, when it is necessary to increase the clamping force between the clamping arms 2, the adjusting knob 5 is rotated before clamping the workpiece to increase the current flowing through the first electromagnet 3, thereby enhancing the magnetic field strength generated by the first electromagnet 3 and increasing the attractive force between the two clamping arms 2. When it is necessary to decrease the clamping force between the clamping arms 2, the adjusting knob 5 is rotated before clamping the workpiece to decrease the current flowing through the first electromagnet 3, thereby weakening the magnetic field strength generated by the first electromagnet 3 and decreasing the attractive force between the two clamping arms 2. On the one hand, this allows users to flexibly adjust the clamping force between the clamping arms 2 according to the characteristics of the workpiece and the application scenario, aiming to improve the versatility and adaptability of the electromagnetic gripper mechanism. On the other hand, for fragile or sensitive workpieces, the clamping force can be reduced to lower the risk of workpiece damage; at the same time, for heavier workpieces or workpieces that require firm fixation, the clamping force can be increased to ensure clamping stability.

[0037] Example 3

[0038] Based on the above embodiment 1, in this embodiment, as follows: Figure 1 As shown, the electromagnetic gripper mechanism further includes a third electromagnet 6; the third electromagnet 6 is disposed on the side of the main body 1 away from the gripper arm 2; wherein, the third electromagnet 6 is used to reserve a connection area between the main body 1 and an external device.

[0039] For example, in the implementation process, the above-mentioned electromagnetic gripper mechanism also includes a third electromagnet 6. The third electromagnet 6 is connected to the side of the main body 1 away from the gripper arm 2 by means of screwing, snapping, etc., in order to reduce the risk of the third electromagnet 6 magnetically attracting the magnetic attraction area on the gripper arm 2.

[0040] During use, when the electromagnetic gripper mechanism needs to be installed onto the magnetic components (such as permanent magnets or iron blocks) of external equipment (such as robotic arms or robots), the third electromagnet 6 is energized to generate sufficient attractive force to adhere to the external equipment. When the electromagnetic gripper mechanism needs to be removed from the external equipment (such as robotic arms or robots), the power supply to the third electromagnet 6 is disconnected to reduce or eliminate its attractive force, allowing the electromagnetic gripper mechanism to be removed from the external equipment. The electromagnetic gripper mechanism is quickly connected and disconnected using electromagnetic force, aiming to simplify the assembly process between the electromagnetic gripper mechanism and external equipment, thereby reducing operation time and complexity.

[0041] Example 4

[0042] Based on the above embodiment 1, in this embodiment, as follows: Figure 3 Combination Figure 4 As shown, the clamping arm 2 includes a rod 21, a claw 22, and a force-measuring spring 23; the rod 21 is slidably connected to the main body 1, and the rod 21 is located between the first electromagnet 3 and the second electromagnet 4; the claw 22 is disposed on the side of the rod 21 near the first electromagnet 3, the claw 22 is slidably connected to the rod 21, and the claw 22 slides relative to the rod 21 along the direction from the first electromagnet 3 to the second electromagnet 4; the force-measuring spring 23 is disposed on the side of the rod 21 near the first electromagnet 3, the force-measuring spring 23 extends along the direction from the second electromagnet 4 to the first electromagnet 3, and the end of the force-measuring spring 23 away from the rod 21 is connected to the claw 22.

[0043] For example, in the implementation process, the above-mentioned clamping arm 2 includes a rod body 21, a claw body 22 and a force-measuring spring 23.

[0044] The rod 21 is slidably connected to the main body 1. For example, a mounting groove is formed at one end of the main body 1, a guide rail is installed in the mounting groove, and the two ends of the guide rail are respectively connected to two opposite groove walls of the mounting groove. At the same time, a sliding groove is formed at one end of the rod 21, and the rod 21 is slidably connected to the guide rail of the main body 1 through the sliding groove, thereby achieving the purpose of slidably connecting the rod 21 to the main body 1. The rod 21 is located between the first electromagnet 3 and the second electromagnet 4, and the aforementioned magnetic attraction area is set in the rod 21. This allows the rod 21 to slide linearly along the main body 1 under the action of the first electromagnet 3 and the second electromagnet 4.

[0045] The claw body 22 is disposed on the side of the rod body 21 near the first electromagnet 3, and the claw body 22 can slide relative to the rod body 21 in the direction from the first electromagnet 3 to the second electromagnet 4.

[0046] The force-measuring spring 23 is connected to the side of the rod 21 near the first electromagnet 3 by means of welding or screwing, and the force-measuring spring 23 extends along the second electromagnet 4 toward the first electromagnet 3. The end of the spring away from the rod 21 is connected to the claw body 22 by means of welding or screwing.

[0047] A force-measuring spring 23 typically comprises an elastic body and strain gauges. The elastic body deforms when subjected to an external force. This deformation is usually small and fully recoverable; that is, the elastic body returns to its original state when the external force is removed. The strain gauges are thin sheets made of conductive material and are attached to the elastic body. As the strain gauges deform along with the elastic body, their resistance changes. The change in resistance is proportional to the applied force. This change in resistance can be converted into a measurable voltage signal using a Wheatstone Bridge circuit. A Wheatstone Bridge consists of four resistors, two or four of which can be strain gauges. When no external force is applied, the bridge is in equilibrium; when an external force causes the strain gauges to deform, the bridge becomes unbalanced, producing an output voltage related to the magnitude of the external force.

[0048] During use, when a workpiece needs to be clamped, the first electromagnet 3 is energized to generate a magnetic field. At this time, the first electromagnet 3 attracts the two rods 21 to move closer together, which in turn drives the two claws 22 to move closer together to clamp the workpiece. Simultaneously, the force-measuring spring 23 is compressed, recording the clamping force applied to the workpiece.

[0049] When the workpiece needs to be released, the two second electromagnets 4 are energized to generate a magnetic field. At this time, the two second electromagnets 4 attract the two rods 21 away from each other, thereby causing the two claws 22 to move away from each other to release the workpiece. The force-measuring spring 23 can provide real-time clamping force data, which is intended to allow the user to adjust the current intensity of the first electromagnet 3, thereby optimizing the clamping effect.

[0050] Example 5

[0051] Based on the above embodiment 4, in this embodiment, as follows: Figure 3 or Figure 4 As shown, the clamping arm 2 further includes a sliding sleeve 24 and a sliding rod 25; the sliding sleeve 24 is disposed on the side of the rod body 21 near the first electromagnet 3, and the sliding sleeve 24 extends along the second electromagnet 4 toward the first electromagnet 3; the sliding rod 25 is slidably disposed in the sliding sleeve 24, and the end of the sliding rod 25 away from the rod body 21 is connected to the claw body 22.

[0052] For example, in the implementation process, the aforementioned clamping arm 2 also includes a sliding sleeve 24 and a sliding rod 25. The sliding sleeve 24 is disposed on the side of the rod body 21 near the first electromagnet 3 by means of welding, screwing, or integral molding, and the sliding sleeve 24 extends along the direction from the second electromagnet 4 toward the first electromagnet 3.

[0053] The slide rod 25 is slidably disposed within the slide sleeve 24, and the end of the slide rod 25 away from the rod body 21 is connected to the claw body 22 by means of welding, screwing, or integral molding.

[0054] During operation, when a workpiece needs to be clamped, the first electromagnet 3 is energized to generate a magnetic field. At this time, the first electromagnet 3 attracts the two rods 21 closer together, and the rods 21 cause the two jaws 22 to move closer together. After the jaws 22 clamp the workpiece, the attraction of the first electromagnet 3 to the rods 21 causes the sliding sleeves 24 on the rods 21 to slide along the sliding rods 25 in a direction closer to the jaws 22, thereby compressing the force-measuring spring 23 to clamp the workpiece. The force-measuring spring 23 records the clamping force applied to the workpiece. When the workpiece needs to be released, the two second electromagnets 4 are energized to generate a magnetic field. At this time, the two second electromagnets 4 attract the two rods 21 away from each other, causing the sliding sleeves 24 on the rods 21 to slide along the sliding rods 25 in a direction away from the jaws 22, thereby restoring the force-measuring spring 23 and releasing the workpiece. The combination of the sliding sleeve 24 and the sliding rod 25 effectively ensures that the rod body 21 and the claw body 22 slide relative to each other along a predetermined path, in order to reduce the deviation or instability caused by external factors and thus improve the accuracy of clamping force measurement.

[0055] Example 6

[0056] Based on the above embodiment 5, in this embodiment, as follows: Figure 3 or Figure 4 As shown, the force-measuring spring 23 is disposed inside the sliding sleeve 24, and the two ends of the force-measuring spring 23 are respectively connected to the rod body 21 and the sliding rod 25.

[0057] For example, in implementation, the force-measuring spring 23 is disposed inside the sliding sleeve 24. One end of the force-measuring spring 23 is connected to the rod 21 by welding, screwing, or other means, and the other end of the force-measuring spring 23 is connected to the sliding rod 25 by welding, screwing, or other means. This aims to reduce external interference and ensure that the force-measuring spring 23 only responds to force changes caused by the movement of the sliding rod 25, thereby improving the accuracy and reliability of clamping force measurement.

[0058] Example 7

[0059] Based on the above embodiment 4, in this embodiment, as follows: Figure 3 or Figure 4As shown, the claw body 22 has an arc-shaped structure that bends towards the rod body 21 from the side away from the rod body 21.

[0060] For example, during implementation, the side of the claw 22 away from the rod 21 has an arc-shaped structure that bends towards the rod 21 in the middle. When it is necessary to clamp the workpiece, the first electromagnet 3 is energized to generate a magnetic field, attracting the two rods 21 to move closer together, which in turn drives the two claws 22 to move closer together. At this time, the arc-shaped claw 22 can better fit workpieces of different shapes, especially for circular, elliptical, or other curved surfaces, in order to achieve a tighter contact between the claw 22 and the workpiece, and a more uniform distribution of the clamping force on the workpiece, thereby reducing the risk of the workpiece slipping or falling.

[0061] Example 8

[0062] Based on the above embodiment 4, in this embodiment, as follows: Figure 3 or Figure 4 As shown, a protective pad 7 is provided on the side of the claw body 22 away from the rod body 21.

[0063] For example, during implementation, a protective pad 7 is installed on the side of the claw body 22 away from the rod body 21 by means of adhesion, snap-fit, screw fixation, etc. The protective pad 7 can be made of rubber, silicone, soft plastic, or other materials with cushioning and anti-slip properties to ensure that the protective pad 7 can provide sufficient friction to enhance clamping stability and effectively protect the surface of the workpiece.

[0064] When a workpiece needs to be clamped, the first electromagnet 3 is energized to generate a magnetic field, attracting the two rods 21 closer together, which in turn causes the two jaws 22 to move closer together. At this time, the jaws 22 with protective pads 7 can more safely contact the workpiece surface. On the one hand, the protective pads 7 reduce the risk of the jaws 22 directly contacting the workpiece surface, aiming to reduce the risk of scratches, indentations, and other damage to the workpiece surface caused by friction or pressure during clamping. On the other hand, the protective pads 7 can provide additional friction to the workpiece surface, aiming to enhance clamping stability and thus reduce the risk of the workpiece slipping or falling during clamping. This is especially important when handling smooth or easily slippery workpieces.

[0065] Example 9

[0066] Based on the above embodiment 4, in this embodiment, as follows: Figure 1 As shown, a display screen 9 is provided on the main body 1; the display screen 9 is connected to the adjustment knob 5 and the force measuring spring 23.

[0067] For example, during implementation, a display screen 9 is mounted on the main body 1 via embedded installation, adhesive fixing, or screw fixing. The display screen 9 is connected to the adjustment knob 5 and the force-measuring spring 23 via electronic circuitry, wireless communication modules, etc. The aim is to display the currently set current intensity and the actual clamping force on the display screen 9, so that the user can understand the current clamping status.

[0068] Example 10

[0069] Based on the above embodiment 1, as follows Figure 1 As shown in this embodiment, a distance sensor 10 is provided on the clamping arm 2.

[0070] For example, during implementation, a distance sensor 10 is installed on the clamping arm 2 through methods such as embedded installation, adhesive fixing, or screw fixing. The distance sensor 10 can be selected from different types of sensors, such as ultrasonic sensors, infrared sensors, or laser rangefinders. Several distance sensors 10 are provided, and these sensors 10 are evenly distributed around the clamping arm 2.

[0071] During use, the ranging sensor 10 can be connected to an external control device via electronic circuitry or wireless connection. This aims to enable the external control device to determine the presence of obstacles based on the distance information provided by the ranging sensor 10 and take appropriate actions (such as stopping the clamping action, changing direction, or issuing a warning), thereby reducing the risk of workpiece damage or equipment damage due to collisions and improving system safety.

[0072] In this embodiment, the display screen 9 can be an ILI9341 (3.5-inch) TFT LCD screen, an SSD1306 (1.3-inch) OLED screen, etc. The force-measuring spring 23 can be an LCM200 series strain gauge force sensor, a Kistler 9257B piezoelectric force sensor, etc. The adjustment knob 5 can be a Bourns PEC12R-4215F-S0024 encoder-type adjustment knob, a Bourns 3296W-1-504LF adjustable resistance knob, etc. The distance sensor 10 can be an HC-SR04 ultrasonic distance sensor, a VL53L1X laser distance sensor, a Sharp GP2Y0A21YK0F infrared distance sensor, etc.
