Description

Technical Field

[0001] This application relates to the field of resistor manufacturing technology, and in particular to an electric gripper device for resistors. Background Technology

[0002] A resistor is a component used to adjust the resistance value in a circuit. Its basic working principle is that the resistance material impedes the current, causing the current in the circuit to change. The production process of a resistor involves multiple steps, including shaping, cutting, spraying, and packaging. Spraying is mostly done using an aluminum spraying process, which requires the use of clamping fixtures.

[0003] For example, Chinese patent application number CN202323128976.0 discloses a robotic arm for adjusting the positive and negative electrodes of a resistor sheet, relating to the technical field of resistor sheet production equipment. This utility model includes a cylinder, with a clamping assembly slidably connected to the front side wall of the cylinder. An anti-slip sleeve is fitted onto the outer wall of the pneumatic gripper in the clamping assembly. A groove is formed on the front side wall of the cylinder. A mounting plate is welded to the rear side wall of the pneumatic gripper in the clamping assembly, and a slider is welded to the rear side wall of the mounting plate. Pneumatic rods and buffer springs are respectively installed on the two outer walls of the slider. The rear side wall of the cylinder is connected to a pneumatic telescopic rod via an electric rotary connector. A connecting rod is installed on the other end side wall of the pneumatic telescopic rod, and a fixing assembly is installed on the end side wall of the connecting rod.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Common clamping mechanisms for resistor sheets typically use cylinders as the power source. However, most clamping cylinders are conventional cylinders with non-adjustable drive strokes. When clamping and fixing resistor sheets of different sizes, since resistor sheets are precision electronic components, it is easy to damage larger resistor sheets. Utility Model Content

[0007] Common clamping mechanisms for resistor sheets typically use cylinders as the power source. However, most clamping cylinders are conventional cylinders with non-adjustable drive strokes. When clamping and fixing resistor sheets of different sizes, since resistor sheets are precision electronic components, it is easy to damage larger resistor sheets.

[0008] This application provides an electric gripper device for resistive elements, which adopts the following technical solution:

[0009] An electric gripper device for resistive elements includes a base, a drive slider, an electric drive unit, two sets of hinged linkages, two gripper ends, two elastic clamping blocks, and an electronic control module. The electric drive unit is mounted on the base and drives the drive slider to move back and forth along the central axis of the base. One set of hinged linkages is hinged between one side of the base, one side of the drive slider, and one gripper end. The other set of hinged linkages is hinged between the other side of the base, the other side of the drive slider, and the other gripper end. The drive slider drives the two elastic clamping blocks to move closer or further apart through the hinged linkages. The elastic clamping blocks are mounted on the inner side of the gripper ends and are used to contact the resistive element to be gripped. The electronic control module is located between the elastic clamping blocks and the electric drive unit. The electronic control module controls the driving stroke of the electric drive unit by feeding back the magnitude of the squeezing force received by the elastic clamping blocks.

[0011] In one feasible technical solution of this application, wire clips are provided on both opposite sides of the base, and the two first cables are respectively clipped into the wire clips.

[0012] In one feasible technical solution of this application, the inner side of the elastic clamp is provided with a concave arc groove, and the concave arc groove is provided with anti-slip stripes.

[0013] In one feasible technical solution of this application, the thickness of the elastic clamp is between 6 and 15 mm.

[0014] In one feasible technical solution of this application, the electric drive unit includes a servo motor and a drive screw. The drive screw is rotatably mounted on the central axis of the base. The servo motor is mounted on the base. The output shaft of the servo motor is connected to the drive screw. The drive screw and the drive slider are threadedly connected.

[0016] In one feasible technical solution of this application, the hinged linkage assembly includes a bent linkage, a first transmission rod, and a second transmission rod. The bent linkage is located between the first transmission rod and the second transmission rod. The two ends of the first transmission rod are respectively hinged to the side of the driving slider and the middle of the bent linkage. The two ends of the bent linkage are respectively hinged to the inner side of the base and the inner end of the gripper end. The two ends of the second transmission rod are respectively hinged to the outer side of the base and the outer end of the gripper end.

[0017] In one feasible technical solution of this application, hinge seats are provided on both opposite sides of the base, and the ends of the bent connecting rod and the first transmission rod are hinged to the hinge seats.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] After the electric drive unit is started, it can drive the drive slider to move back and forth. Then, through the transmission action of two sets of hinged linkages, it can drive the two sets of elastic clamps to move closer or further apart. Unlike the common cylinder drive mode, when clamping resistors of different sizes, this device can control the electric drive unit to stop working when the squeezing force received by the elastic clamps reaches the preset pressure value, based on feedback from the electronic control module. As a result, the two sets of elastic clamps will no longer continue to clamp the resistor in the middle. This provides greater flexibility, effectively prevents the clamped resistor from being squeezed and damaged, and provides good protection for the resistor. Attached Figure Description

The elastic clamping blocks 6 are mounted on the inner side of the gripper ends 5 and are used to contact the resistive sheet to be gripped. The electronic control module 7 is located between the elastic clamping blocks 6 and the electric drive unit 3.

[0036] In this embodiment, the electronic control module 7 controls the driving stroke of the electric drive unit 3 by feeding back the squeezing force received by the elastic clamping block 6.
