Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0040] The following describes a resistance value detection device for an alloy resistor according to an embodiment of the present application with reference to the accompanying drawings.

[0041] See also Figure 1-Figure 11 According to an embodiment of the present application, a resistance value detection device for an alloy resistor includes: a bracket detection main body 1, a lifting mechanism 2, a probe component 3, a reciprocating lifting mechanism 4 and a resistor placement mechanism 5.

[0042] Among them, the bracket detection main body 1 is used to support the installation of the lifting mechanism 2, the reciprocating lifting mechanism 4 and the resistor placing mechanism 5. The alloy resistor to be detected is placed above the resistor placing mechanism 5. The reciprocating lifting mechanism 4 drives the alloy resistor on the resistor placing mechanism 5 to move upward and contact with the bottom of the resistor placing mechanism 5, so that the resistance value detection of the alloy resistor can be quickly completed.

[0043] See also Figure 1-Figure 3 and Figure 8The main part 1 of the bracket detection includes a frame 11, a table 12, a resistance detector body 13 and a back frame 14. The table 12 is fixed to the top of the frame 11 by welding, the back frame 14 is arranged on the back of the frame 11, and the resistance detector body 13 is installed on the top of the back frame 14. The lifting mechanism 2 includes a mounting frame 21 and a lifting part 22. The mounting frame 21 is fixed to the upper rear side of the table 12 by bolts, and the lifting part 22 is installed on the front side of the mounting frame 21. The probe component 3 is installed at the bottom of the lifting part 22. The reciprocating lifting mechanism 4 includes a back plate 41, a front plate 42, a rotation drive assembly 43, a cam 44, a support block 45, a second spring 46 and a push rod 47. The back plate 41 and the front plate 42 are fixed to the rear side and the front side of the frame 11 respectively, the rotation drive assembly 43 is installed between the back plate 41 and the front plate 42, and the rotation drive assembly 43 drives the cam 44 to rotate, the support block 45 is located above the cam 44, and the bottom surface of the support block 45 contacts the cam 44, the bottom end of the push rod 47 is fixedly arranged on the upper surface of the support block 45, and the push rod 47 slides through the table 12, the second spring 46 is sleeved on the outside of the push rod 47 located between the table 12 and the support block 45, and the top of the push rod 47 is provided with a first hemispherical block 48. The resistor placement mechanism 5 includes a seat frame 51 and a placement plate 52, the seat frame 51 is fixed above the table 12, the placement plate 52 is movably arranged at the front side of the seat frame 51, the upper surface of the placement plate 52 is provided with a placement groove 53, the placement groove 53 is located below the probe component 3, and the upper surface of the placement plate 52 is provided with a feed trough 54 connected with the placement groove 53.

[0044] The working principle of the resistance value detection device of the alloy resistor is as follows: the rotating driving component 43 drives the cam 44 to rotate, and the rotating cam 44 drives the upper support block 45 to reciprocate in the vertical direction, that is, drives the push rod 47 above the support block 45 to reciprocate in the vertical direction. When the push rod 47 is at the lowest position in the vertical direction, the alloy resistor is placed from the side of the placement groove 53 above the placement plate 52, so that the end of the alloy resistor is against the port of the placement groove 53, and the alloy resistor is located below the probe component 3 at this time. The rotating driving component 43 drives the cam 44 to rotate continuously, and when the cam 44 drives the support block 45 and the push rod 47 to move upward to the highest point, the alloy resistor is in contact with the probe component 3 at this time, and cooperates with the resistance detector body 13 to detect the resistance value of the alloy resistor, and at the same time the second spring 46 is in a compressed state. When the rotating driving assembly 43 continuously drives the cam 44 to rotate, the push rod 47 moves downward under the elastic force of the second spring 46, that is, the placement plate 52 and the alloy resistor to be tested thereon are separated from the contact with the probe component 3, and the tested alloy resistor can be unloaded from the unloading slot 54, and then a new alloy resistor can be loaded from the placement slot 53, so that the resistance value of the resistor can be quickly tested. Compared with the traditional manual method of placing probes or clips at both ends of the alloy resistor for testing, it is more efficient.

[0045] In order to improve the detection efficiency, the material can be loaded in advance, and the specific operation method is as follows: at least two alloy resistors can be placed in the placement groove 53, one is the alloy resistor to be detected, and the other is the alloy resistor to be detected. After the resistance value detection of the alloy resistor located below the probe component 3 is completed, during the lowering process of the placement plate 52, the operator can remove the detected alloy resistor from the unloading groove 54 with one hand, and then insert the new third alloy resistor to be detected from one end of the placement groove 53, and the original alloy resistor to be detected is pushed to the bottom of the probe component 3, completing the rapid loading and unloading of the alloy resistor, which can further improve the detection efficiency of the alloy resistor.

[0046] The placement plate 52 of the resistance value detection device of the above-mentioned alloy resistor drives the alloy resistor in the placement slot 53 to move up and down. When the alloy resistor on the placement slot 53 is unloaded from the unloading slot 54, the operator needs to take it off manually. If the alloy resistor after detection can be unloaded from the unloading slot 54 by itself, it can further facilitate the operator to perform resistance detection operations.

[0047] See also Figure 2 , Figure 8 and Fig. 9 The resistance value detection device of the alloy resistor further provides an embodiment, wherein a connection block 56 is fixed to the back of the placement plate 52 by welding, and a shaft 55 is arranged at the rear side of the connection block 56. A bearing seat is installed on the front of the seat frame 51 to rotate with the shaft 55, a guide groove 59 is arranged at the bottom of the placement plate 52 to match the first hemispherical block 48 at the top of the top rod 47, and a convex plate 17 is fixed in front of the table 12, and the convex plate 17 and the table 12 are integrally formed. A collection box 18 is arranged above the convex plate 17, and the collection box 18 is located below the front side of the material discharge chute 54.

[0048] The rotating drive assembly 43 drives the cam 44 to rotate, and the rotating cam 44 drives the support block 45 and the push rod 47 to reciprocate in the vertical direction. When the push rod 47 is at the lowest position, the placement plate 52 supported by the first hemispherical block 48 at the top of the push rod 47 is in a downward tilted position, and the alloy resistor is placed in the placement groove 53. At this time, the alloy resistor to be loaded is supported by fingers. The push rod 47 gradually moves upward to rotate the placement plate 52 above around the shaft 55 through the first hemispherical block 48. When the push rod 47 is at the highest position, the first hemispherical block 48 supports the placement plate 52 above in a horizontal position. At this time, the probe component 3 contacts the alloy resistor to be detected inside the placement groove 53, and the hand that is supporting the alloy resistor can be moved out when in contact, ready to load a new alloy resistor from the placement groove 53. When the rotating driving assembly 43 drives the top rod 47 to move downward, the tested alloy resistor tilts downward around the shaft 55 under the weight of the placement plate 52, and the tested alloy resistor slides down the feeding trough 54 to the inside of the collection box 18 for collection. The feeding trough 54 in this embodiment is preferably arranged in a vertical position with the placement trough 53, so that the alloy resistor loaded from the placement trough 53 is easier to be positioned by holding it with fingers from one end of the alloy resistor, and two alloy resistors can be loaded from the placement trough 53, and the alloy resistor to be tested is contacted with the inner end wall of the placement trough 53 while holding the latter alloy resistor. After releasing the hand, the tested alloy resistor can be discharged by itself along the inclined feeding trough 54. This design scheme can further improve the convenience of alloy resistor detection.

[0049] When the first hemispherical block 48 on the top of the push rod 47 reciprocates in the vertical direction, the first hemispherical block 48 is always in contact with the inner wall of the guide groove 59 , that is, the setting of the guide groove 59 is used to stabilize the rotation of the placement plate 52 around the shaft 55 .

[0050] For specific settings, see Figure 4 The lifting part 22 includes a support plate 221, a fixed seat 222, a lead screw 223 and a hand wheel 224. The fixed seat 222 is installed at the front side of the mounting frame 21, the lead screw 223 is screwed through the fixed seat 222, and the hand wheel 224 is arranged at the top of the lead screw 223, the bottom of the lead screw 223 is rotatably connected with the support plate 221, and the probe component 3 is installed at the front end of the support plate 221. The hand wheel 224 is rotated to drive the lead screw 223 to rotate, and the rotating lead screw 223 drives the support plate 221 to move in the vertical direction to adjust the distance between the probe component 3 and the placement plate 52 through the screw connection with the fixed seat 222, that is, the distance between the probe component 3 and the alloy resistor to be detected can be adjusted, and the height position can be fine-tuned according to the actual production needs, which has better applicability.

[0051] Further, a guide rod 226 is fixed above the rear end of the support plate 221, and a support 225 is provided on the back of the mounting frame 21, and the guide rod 226 movably penetrates the support 225. The arrangement of the support 225 and the guide rod 226 enables the support plate 221 to be adjusted more smoothly in the vertical direction.

[0052] Specifically, see Figure 6 , the probe component 3 includes a detection probe 31, a movable block 33 and a fixed block 37. The movable block 33 and the fixed block 37 are both arranged on the front side of the support plate 221, and the two groups of detection probes 31 are respectively arranged at the bottom of the movable block 33 and the fixed block 37. A seat block is arranged on the top of the detection probe 31, and a limiting rod 32 is fixed on the top of the seat block, and the limiting rod 32 is movably connected with the movable block 33 and the fixed block 37 respectively, and the first spring 36 is sleeved on the outside of the limiting rod 32. The detection probe 31 in the probe component 3 contacts the end of the alloy resistor, and cooperates with the resistance detector body 13 to detect the resistance value of the alloy resistor. The setting of the first spring 36 and the limiting rod 32 enables the detection probe 31 to have a certain buffering performance when contacting the alloy resistor, and has a good protective effect on the detection probe 31 and the alloy resistor.

[0053] For further information, see Figure 5-Figure 7 The probe component 3 also includes a transverse adjustment portion 34, which connects the fixed block 37 and the movable block 33. The transverse adjustment portion 34 includes a first threaded rod 341, a second threaded rod 342 and a sleeve 343. A section of the first threaded rod 341 is fixedly connected to the fixed block 37, one end of the second threaded rod 342 is fixedly connected to the movable block 33, and two ends of the sleeve 343 are respectively screwed to the first threaded rod 341 and the other end of the second threaded rod 342, and the first threaded rod 341 and the second threaded rod 342 are arranged in opposite directions of thread rotation, a nut 344 is fixedly sleeved on the outside of the sleeve 343, a slide groove 227 is arranged on the front side of the support plate 221, and a slider 35 slidably matched with the slide groove 227 is fixed to the rear side of the movable block 33. By rotating the nut 344 in the lateral adjustment part 34, the rotating nut 344 drives the sleeve 343 to rotate. At this time, through the cooperation of the first threaded rod 341 and the second threaded rod 342, the distance between the movable block 33 and the fixed block 37 is adjusted, that is, the distance between the two groups of detection probes 31 is adjusted. According to the different specifications of the loaded alloy resistor, the detection point position can be adjusted appropriately.

[0054] For specific settings, see Figure 3The rotation drive assembly 43 includes a motor 431, a driving pulley 432, a driven pulley 433, a transmission belt 434 and a transmission shaft 435. The transmission shaft 435 is rotatably arranged between the back plate 41 and the front plate 42. The motor 431 is installed in front of the back plate 41, and the driving pulley 432 is fixedly arranged at the output shaft end of the motor 431. The driven pulley 433 and the cam 44 are both fixedly sleeved on the outside of the transmission shaft 435. The transmission belt 434 connects the driving pulley 432 and the driven pulley 433. The output shaft end of the motor 431 in the rotation drive assembly 43 drives the driving pulley 432 to rotate, and the driving shaft 435 is driven to rotate through the cooperation of the driven pulley 433 and the transmission belt 434, that is, the cam 44 on the transmission shaft 435 is driven to rotate.

[0055] For further information, see Figure 1 The bottom of the frame 11 is provided with supporting feet 15 and moving wheels 16. The supporting feet 15 are height-adjustable legs, and the moving wheels 16 are provided to facilitate the transfer of the entire device.

[0056] When the above-mentioned alloy resistor resistance value detection device is in use, when multiple alloy resistors are loaded into the placement groove 53 in the placement plate 52, the alloy resistors are prone to loosening in the junction area between the placement groove 53 and the feed groove 54, that is, the alloy resistors may slide and move along the feed groove 54 before being detected, resulting in the probe component 3 being unable to accurately fall on the alloy resistor.

[0057] See also Figure 8-Figure 11 The resistance value detection device of the alloy resistor also includes a linkage pressing mechanism 6, which includes a V-shaped pressing rod 61, a pin 62, a connecting seat 63 and a magnetic cross bar 64. The feed trough 54 is an arc-shaped structure. A positioning block 57 is provided at the top of the feed trough 54, and a positioning groove 58 connected to the feed trough 54 is provided on the placement plate 52. A first limit block 571 and a second limit block 572 are integrally formed on the outer side of the positioning block 57. A first limiting groove 581 and a second limiting groove 582 which are connected to the first limiting groove 581 are provided at the bottom of the placement plate 52. The first limiting block 571 slides in cooperation with the first limiting groove 581, and the second limiting block 572 slides in cooperation with the second limiting groove 582. Two connecting seats 63 are respectively located on both sides below the positioning groove 58 and fixed to the bottom of the placement plate 52. The pin shaft 62 is rotatably provided between the two connecting seats 63. The pin shaft 62 is fixedly passed through the pressure rod 61. A second hemispherical block 65 is provided at the top of the pressure rod 61, and the second hemispherical block 65 is in contact with the positioning block 57 and the bottom of the second limiting block 572. A magnetic cross bar 64 is provided at the bottom of the pressure rod 61, and the magnetic cross bar 64 is in magnetic adsorption contact with the top rod 47.

[0058] When the rotating driving assembly 43 drives the cam 44 to rotate, the rotating cam 44 will drive the upper support block 45 and the push rod 47 to reciprocate in the vertical direction. At least two alloy resistors can be placed inside the placement groove 53. When the placement plate 52 moves upward around the shaft 55, the first hemispherical block 48 at the top of the push rod 47 moves from the lower right to the upper side along the guide groove 59, and at the same time, the push rod 47 also moves toward the side of the seat frame 51 against the magnetic cross bar 64, and the magnetic cross bar 64 moves while driving the pressure rod 61 to rotate around the pin 62. The second hemispherical block 65 at the top of the rotating pressure rod 61 is connected with the second limiting block 572 and the bottom of the positioning block 57, so that the top of the positioning block 57 rises from the positioning groove 58 to the top of the bottom surface of the feeding trough 54. At this time, the positioning block 57 protruding from the positioning groove 58 can be used to limit the alloy resistor to be detected to prevent the alloy resistor from being loosened when not detected. When the alloy resistor test is finished, the push rod 47 moves downward along the guide groove 59, and at the same time, the magnetic cross bar 64 is adsorbed on the outside of the push rod 47 to drive the pressure rod 61 to rotate around the pin 62 and drive the second hemispherical block 65 to move downward. Under the action of gravity, the positioning block 57 completely falls into the positioning groove 58. At this time, when the next alloy resistor is loaded, the previous alloy resistor will be squeezed into the lower feeding trough 54. The tested alloy resistor slides from the lower feeding trough 54 to the collection box 18 for collection. After the positioning block 57 protrudes above the bottom wall of the lower feeding trough 54 again, a new alloy resistor is loaded into the placement groove 53 again to cooperate with the positioning block 57 to resist the previous alloy resistor, so that the alloy resistor can be stably connected to the probe component 3, and the stability of the alloy resistor during detection can be improved while maintaining the convenience of the detection operation.
