As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0032] Referring to Figure 3 The alloy resistance repairing device 10 is used for repairing the alloy resistance 20 semi-finished product, and comprises a feeding mechanism, a transfer mechanism 200, a jig 300 and a tester 400. The jig 300 is used for positioning the alloy resistance 20 semi-finished product, and the transfer mechanism 200 drives the jig 300 to move between the feeding mechanism and the tester 400.

[0033] Referring to Figure 3 The feeding mechanism comprises a loading table 110 and a multi-axis manipulator 120. The loading table 110 is used for storing the alloy resistance 20 semi-finished product. The multi-axis manipulator 120 is responsible for picking up the alloy resistance 20 semi-finished product and transferring it to the jig 300 or taking the alloy resistance 20 semi-finished product after the repairing operation from the jig 300.

[0034] Referring to Figure 3 Preferably, the loading table 110 comprises a first support 111 and a second support 112. The first support 111 is used for storing the alloy resistance 20 semi-finished product to be repaired, and the second support 112 is used for storing the alloy resistance 20 semi-finished product after the repairing operation. The first support 111 and the second support 112 are respectively located on the two sides of the multi-axis manipulator 120. In this way, the feeding position and the discharging position of the alloy resistance 20 semi-finished product are both distributed within the pickup range of the multi-axis manipulator 120. The multi-axis manipulator 120 can transfer the product after the repairing operation from the jig 300 to the second support 112 and transfer the next product to be repaired in the first support 111 to the jig 300. The single manipulator can complete the feeding and discharging operations, which is beneficial to saving the manufacturing cost of the equipment and improving the space utilization of the equipment.

[0035] Referring to Figure 3 and Figure 4, the tester 400 comprises a visual detection assembly 410, a trimming table 420, a motor 430 located on the trimming table 420, a ball head cutter 440, and two groups of probes 450 located on both sides of the ball head cutter 440. The probes 450 are used to contact the electrodes 22 on the alloy resistor 20, thereby electrifying the alloy resistor 20, so as to measure the actual resistance value of the alloy resistor 20. The ball head cutter 440 is used to grind the resistor body 21, so as to adjust the resistance value of the alloy resistor 20 to a target value. Preferably, the end of the ball head cutter 440 is arc-shaped, and the cross section of the resistance adjusting groove 23 excavated in the trimming process is also arc-shaped, as shown in Figure 7 , which can reduce the probability of burr generated in the trimming process, thereby avoiding burr leading to resistance packaging defects and reducing the probability of generating defective products. The visual detection assembly 410 photographs the picture of the alloy resistor 20 after the trimming operation, so as to judge whether the trimming process causes damage to the alloy resistor 20, thereby facilitating the subsequent work station to sort out defective products.

[0036] Please refer to Figure 4 , Figure 5 and Figure 6 , the probe 450 comprises a T-shaped insulating sleeve 451, a conductive insert 452, and a metal rod 453. The trimming table 420 is provided with a sliding groove 421, and the inner wall of the sliding groove 421 is provided with a terminal 422. The T-shaped insulating sleeve 451 is slidably arranged in the sliding groove 421. The conductive insert 452 penetrates through the T-shaped insulating sleeve 451, and the position of the conductive insert 452 exposed outside the T-shaped insulating sleeve 451 is attached to the terminal 422. The metal rod 453 is embedded in the conductive insert 452, and the metal rod 453 is used to contact the electrode on the alloy resistor semi-finished product. The terminal 422, the conductive insert 452, and the metal rod 453 are conductive components. When the metal rod 453 contacts the electrode 22 of the alloy resistor 20, it is electrified to measure the resistance value, as shown in Figure 6 . The T-shaped insulating sleeve 451 and the sliding groove 421 translate. When alloy resistors 20 of other specifications need to be produced, the T-shaped insulating sleeve 451 can be slid to adjust the position of the metal rod 453, so that it can be aligned with the electrode 22 of the alloy resistor 20. Since the distance between the two groups of probes 400 is adjustable, the tester can meet the trimming needs of alloy resistors 20 of different sizes.

[0037] The working principle of the above alloy resistor trimming device 10 is as follows:

[0038] After storing the alloy resistor 20 semi-finished product on the material loading table 110, the device is started. The multi-axis manipulator 120 picks up the alloy resistor 20 semi-finished product and transfers it to the jig 300. The transfer mechanism 200 drives the jig 300 to move to the position of the tester 400, and makes one of the alloy resistors 20 on the semi-finished product located below the ball head cutter 440.

[0039] Then, the resistance repairing platform 420 is lowered, the metal rods 453 on the two sets of probes 450 first contact the electrodes 22 of the alloy resistor 20, and the actual resistance value of the alloy resistor 20 is measured. If the resistance value meets the standard, the resistance repairing platform 420 is raised, and after the metal rods 453 are separated from the electrodes 22, the jig 300 is translated by the transfer mechanism 200 to move the next alloy resistor 20 under the ball head cutter 440 and repeat the above operation to measure the actual resistance value of the alloy resistor 20. When the resistance value of the measured alloy resistor 20 does not meet the standard, the motor 430 drives the ball head cutter 440 to rotate, and the end of the ball head cutter 440 grinds the resistor body 21 of the alloy resistor 20. The transfer mechanism 200 translates, and the transfer mechanism 200 cooperates with the ball head cutter 440 to dig the resistance adjusting groove 23 in the resistor body 21. Since the resistor body 21 is partially removed, the resistance value of the alloy resistor 20 decreases accordingly, and the ball head cutter 440 stops grinding when the resistance value decreases to the target value, thereby ensuring the consistency of the resistance value of the alloy resistor 20.

[0040] The alloy resistor resistance repairing device 10 has the following beneficial effects:

[0041] 1. The T-shaped insulating sleeve 451 can slide in the sliding groove 421, and by adjusting the distance between the two T-shaped insulating sleeves 451 on both sides of the ball head cutter 440, the two metal rods 453 can contact the electrodes on alloy resistors of different sizes, so that the probe 450 can adapt to the resistance repairing needs of alloy resistors of various sizes.

[0042] 2. The ball head cutter 440 can reduce burrs generated during resistance repairing and avoid defects caused by resistance repairing errors.

[0043] Please refer to Figure 5 In an embodiment, an avoiding groove 11 is formed on one side of the T-shaped insulating sleeve 451 close to the terminal 422. This avoids the T-shaped insulating sleeve 451 from contacting the terminal 422, reducing the resistance during sliding. Conversely, the T-shaped insulating sleeve 451 will wear the terminal 422 during sliding.

[0044] Please refer to Figure 6 In an embodiment, the metal rod 453 includes a connecting part 41 and a contact end 42. The connecting part 41 is connected to the conductive insert 452, and the contact end 42 is bent towards the position of the jig 300. During resistance repairing, the contact end 42 of the metal rod 453 contacts the electrode 22 to electrify the alloy resistor 20 to be repaired, thereby detecting the resistance value of the target alloy resistor 20.

[0045] In an embodiment, an insulating layer is provided on the surface of the resistance repairing platform 420 to reduce the probability of short circuit during resistance repairing.

[0046] Please refer to Figure 5 In an embodiment, a shaft coupling 460 is provided between the ball head cutter 440 and the motor 430 to facilitate replacement of the ball head cutter 440.

[0047] Referring to Figure 3 In an embodiment, the transfer mechanism 200 comprises a horizontal sliding platform 210 and a vertical sliding rail 220, the horizontal sliding platform 210 and the vertical sliding rail 220 are perpendicular to each other, the horizontal sliding platform 210 is used to drive the horizontal translation of the jig 300, and the vertical sliding rail 220 is used to drive the horizontal translation of the jig 300, so that each alloy resistor is moved below the ball cutter 440, and the alloy resistor 20 can be horizontally and vertically moved during the resistance trimming process, so as to improve the resistance trimming accuracy.

[0048] Referring to Figure 4 In an embodiment, the visual detection assembly 410 comprises a CCD camera 411 and a motorized sliding rail 412, the motorized sliding rail 412 is used to drive the CCD camera 411 to move, so as to adjust the orientation of the CCD camera 411, and the shooting position of the ball cutter 440 is adjustable, so as to avoid the ball cutter 440 or the probe 450 from shielding the alloy resistor 20 during the resistance trimming process.

[0049] The above-mentioned embodiments only express several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
