[0002] A resistor is a plate-shaped resistive product used to measure strain, converting changes in strain on a mechanical component into changes in resistance. Resistors are stored in resistor hoppers, which are specialized devices for storing, managing, and orderly supplying resistors.

[0044] Example 1
[0045] Please refer to Figure 1-3 This embodiment provides a resistor sheet feeding device, including: a first servo mechanism 53 (X-axis), a carrier 57, a second servo mechanism 56 (Z-axis), and an actuator 55 mounted on the second servo mechanism 56. The first servo mechanism 53 is arranged along a first direction; the carrier 57 is connected to the first servo mechanism 53; the carrier 57 is used to fix the resistor sheet hopper 52, and the carrier 57 has an operating hole (e.g., ...). Figure 3The device can enter the resistor sheet hopper 52 from the bottom through the operating hole; the second servo mechanism 56 is vertically connected to the first servo mechanism 53, and the second servo mechanism 56 is arranged along a second direction; the actuator 55 is connected to the second servo mechanism 56; the actuator 55 is driven by the second servo mechanism 56 to move along the second direction and extend into the resistor sheet hopper 52 to push the resistor sheet. At the same time, the carrier 57 or the second servo mechanism 56 is driven by the first servo mechanism 53 to move along a first direction.
[0046] The aforementioned resistor sheet feeding device adopts a dual-servo linkage + carrier 57 design, consisting of a first servo mechanism 53 (X-axis), carrier 57, a second servo mechanism 56 (Z-axis), and a material handling actuator (actuator 55). These modules work together to achieve precise and flexible feeding of resistor sheets. In the first operating mode of the resistor sheet feeding device, the first servo mechanism 53 on the X-axis drives the carrier 57 (which carries a resistor sheet hopper 52 containing resistor sheets) to move to the second servo mechanism 56 on the Z-axis (the second servo mechanism 56 is fixed) for lateral positioning. The second servo mechanism 56 on the Z-axis controls the actuator 55 to vertically pass through the operating hole of the carrier 57 and extend into the resistor sheet hopper 52, pushing the resistor sheet upwards to a suitable material handling window for gripping / picking up the resistor sheet, thus achieving feeding. The second operating mode of the resistor sheet feeding device is as follows: the first servo mechanism 53 of the X-axis drives the second servo mechanism 56 of the Z-axis to move to the carrier 57 (the carrier 57 carries the resistor sheet hopper 52, which stores resistor sheets; the carrier 57 is fixed) to achieve lateral positioning. The second servo mechanism 56 of the Z-axis controls the actuator 55 to pass vertically through the operating hole of the carrier 57 and extend into the resistor sheet hopper 52, pushing the resistor sheet upward to a suitable pick-up window for picking up the resistor sheet, thereby achieving feeding. The above-mentioned resistor sheet feeding device adopts a dual servo linkage + carrier 57 design, realizing multi-station resistor sheet feeding of the resistor sheet hopper 52 through orthogonal motion. The feeding is flexible and convenient, and the resistor sheet picking / grabbing is convenient, fast, and time-saving. The carrier 57 can be designed as a modular structure, compatible with resistor sheet hoppers 52 of different sizes. The resistor sheet hopper 52 is compatible with resistor sheets of different sizes, greatly improving the flexibility of resistor sheet supply and its adaptability to different resistor sheets.
[0047] like Figure 1 , 2 In one embodiment shown, the carrier 57 is slidably connected to the first servo mechanism 53, and the carrier 57 is configured to move along a first direction driven by the first servo mechanism 53; the second servo mechanism 56 is fixedly connected to the first servo mechanism 53 via a bracket. In this design, the second working mode of the resistor sheet feeding device has been described above and will not be repeated.
[0048] like Figure 1 , 2In one embodiment shown, the first servo mechanism 53 includes an X-axis module, which includes an X-axis linear guide rail 533 and a first slider 532 disposed on the X-axis linear guide rail 533. The X-axis linear guide rail 533 is arranged along a first direction, and its surface can be hardened to ensure wear resistance. The first slider 532 is slidably connected to the X-axis linear guide rail 533. A first linear drive mechanism 531 is connected to the first slider 532. The first slider 532 can integrate multiple sets of circulating ball bearings, and has a built-in sealing scraper to prevent dust intrusion. The first linear drive mechanism 531 drives the first slider 532 to move the carrier 57 along the X-axis linear guide rail 533. The servo system controls the precise movement of the first slider 532 (and the carrier 57 connected to it) in the X-axis direction (first direction), with a controllable stroke range. Multiple workstations can be set, with multiple preset feeding / removing workstations. The carrier 57 can flexibly switch to different workstations to achieve feeding, significantly improving feeding efficiency.
[0049] In one embodiment, the first linear drive mechanism 531 is configured as a ball screw, a synchronous belt drive mechanism, or a linear motor. The nut of the ball screw is connected to the first slider 532, and the servo motor drives the screw to push the nut and the first slider 532 to move back and forth. In the synchronous belt drive mechanism, the first slider 532 engages with the synchronous belt, and the servo motor, by driving the synchronous belt, pulls the first slider 532 to move back and forth. In the linear motor, the mover is connected to the first slider 532, and the linear motor, based on the principle of electromagnetic induction and the interaction between electromagnetic forces, drives the mover to move the first slider 532.
[0050] like Figure 1 , 2 In one embodiment shown, the second servo mechanism 56 includes a Z-axis module, which comprises a Z-axis linear guide 561 and a second slider 562 disposed on the Z-axis linear guide 561. The Z-axis linear guide 561 is arranged along a second direction. The second slider 562 is slidably connected to the Z-axis linear guide 561. A second linear drive mechanism 563 is drively connected to the second slider 562 and is used to drive the second slider 562 to move along the Z-axis linear guide 561. The servo system controls the precise movement of the second slider 562 (and its connected actuator 55) in the Z-axis direction (second direction), with controllable stroke range and speed. A piezoelectric force sensor can be built into the actuator 55 to prevent overpressure damage to the resistor sheet during pushing. As the resistor sheet moves away, the actuator 55 continuously pushes the remaining resistor sheet to the feeding window, achieving continuous feeding of the resistor sheet and significantly improving feeding efficiency. The selection method of the second linear drive mechanism 563 is the same as that of the first linear drive mechanism 531.
[0051] like Figure 2 , 3In one embodiment shown, the carrier 57 includes a tray 572 and fixing blocks 571 disposed on the tray 572; wherein the tray 572 has an operating hole; the fixing blocks 571 are disposed on the upper surface of the tray 572; the fixing blocks 571 are arranged in pairs, and the pairs of fixing blocks 571 are used to abut against the two apex corners of the bottom of the resistor chip hopper 52 located on the diagonal to fix the resistor chip hopper 52. Preferably, the fixing blocks 571 are L-shaped with an inner angle of 90°, and the inner angle of the fixing blocks 571 cooperates with the apex corner of the bottom of the resistor chip hopper 52; the inner side of the fixing blocks 571 is chamfered, and the chamfer is used to guide the resistor chip hopper 52 to slide between the pairs of fixing blocks 571, thereby improving the clamping efficiency of the resistor chip hopper 52 and enabling precise installation. By adjusting the installation position of the fixing blocks 571, it can adapt to the clamping of different resistor chip hoppers 52, facilitating transformation.
[0052] like Figure 1 In one embodiment shown, the actuator 55 can be a carbon fiber tube with embedded copper wires inside to eliminate static electricity. The actuator 55 has a flexible contact end with silicone to buffer the impact force during pushing and prevent scratching the surface of the resistor.
[0053] like Figure 2 In one embodiment shown, the resistor feeding device includes a frame 54; the frame 54 supports the second servo mechanism 56 and the resistor feeding device. Preferably, the frame 54 is located at the bottom of the second servo mechanism 56 and extends along a second direction.
[0054] like Figure 2 In one embodiment shown, the resistor sheet feeding device includes: an optical fiber mechanism 51 disposed on both sides of the carrier 57 and corresponding to the resistor sheet hopper 52, used to detect the placement status of the resistor sheet and whether the resistor sheet is accurately grasped by utilizing changes in reflected / transmitted light intensity. The optical fiber mechanism 51 is preferably configured to be height-adjustable.
[0055] The resistor sheet feeding device of this utility model adopts a dual servo linkage + carrier 57 design, which consists of a first servo mechanism 53 (X-axis), carrier 57, second servo mechanism 56 (Z-axis) and material picking execution mechanism (execution rod 55). The first servo mechanism 53 and the second servo mechanism 56 realize multi-station resistor sheet feeding of resistor sheet hopper 52 through orthogonal motion. The modules work together to achieve accurate resistor sheet feeding, which is flexible and convenient. The resistor sheet picking / grabbing is convenient, fast and time-saving.

[0058] To elaborate.
[0059] The resistor sheet storage compartments in the resistor sheet hopper are pre-stored with resistor sheets, and these compartments can be arranged in multiple rows side-by-side. Resistor sheets in each compartment are stacked sequentially along the height of the compartment to form a stack. A resistor sheet feeding device pushes a stack of resistor sheets from the bottom of a row of compartments within the hopper, moving the top resistor sheet to the picking window at the top of the compartment. Then, the linear module of the resistor sheet feeding device drives a suction cup to the picking window, aligns it with the resistor sheet, and picks it up. The linear module continues to drive the suction cup, moving the resistor sheet to a preset position, releasing it, thus completing the resistor sheet feeding operation.
