Description

[0002] Resistors are one of the basic components in circuits, and the accuracy of their resistance values ​​directly affects the performance and function of the circuit. By detecting resistors, we can promptly discover deviations or faults in the resistance values, ensuring that the circuit can operate normally according to the design requirements and avoiding problems such as circuit short circuits, open circuits, and signal abnormalities.

[0003] In the current technical field, the commonly used resistance detection method is to place the resistors to be tested one by one inside a special detection device. During the specific operation, the two pins of the resistor need to be carefully connected to the two ends of the detection device respectively to ensure good and stable electrical contact. Subsequently, relying on the precision circuits and algorithms inside the detection device, the resistance value of the resistor is accurately judged and analyzed to verify whether it meets the predetermined standards or specifications. However, this traditional detection method has an obvious efficiency bottleneck. Since only a single resistor can be detected at a time, and the resistors need to be connected to the detection device manually or semi-automatically in turn, the whole process is time-consuming and cumbersome to operate, resulting in low detection efficiency, which is difficult to meet the needs of large-scale, high-efficiency production and detection.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figures 1 to 9 As shown, a feeding mechanism for resistance detection includes a bottom plate 1, two vertical plates 2 are vertically arranged on the bottom plate 1, a plurality of arc grooves 201 for placing resistors 3 are continuously arranged above the vertical plates 2, a top plate 4 is slidably arranged between the two vertical plates 2, a plurality of inclined grooves 401 for lifting the resistors 3 are arranged above the top plate 4, and the number of the arc grooves 201 and the inclined grooves 401 are the same, a main shaft 5 is rotated together on the two vertical plates 2, a cam 6 for driving the top plate 4 to move is arranged on the main shaft 5 and located between the two vertical plates 2, and the cam 6 is in contact with the bottom of the top plate 4.

[0029] Specifically, the pins at both ends of the resistor 3 are respectively placed in the arc grooves 201 of the two vertical plates 2. Due to the automatic gravity of the top plate 4, the bottom of the top plate 4 is always in contact with the cam 6. The main shaft 5 drives the cam 6 to rotate, and the cam 6 drives the top plate 4 to move up and down between the two vertical plates 2. When the top plate 4 rises, the inclined groove 401 on the top plate 4 pushes the resistor 3 upward from the arc groove 201. After the resistor 3 leaves the arc groove 201, the resistor 3 slides along the inclined groove 401 to the top of the next adjacent arc groove 201. When the top plate 4 falls, the resistor 3 is placed in the next adjacent arc groove 201, and the inclined groove 401 is separated from the resistor 3. By sliding the top plate 4 back and forth between the two pieces, the resistor 3 can be moved forward in the vertical plate 2 and the arc groove 201 in sequence.

[0030] A clamping assembly is provided on the outer side of the two vertical plates 2, and the clamping assembly includes a cam 2 7 fixed on the main shaft 5, and the cam 2 7 is arranged in the opposite direction to the cam 1 6. The lower part of the cam 2 7 contacts with a flat plate 8, and the upper part of the flat plate 8 is connected with a slide bar 9, and the slide bar 9 is slidably arranged on the corresponding vertical plate 2. The upper part of the slide bar 9 is connected with a semicircular plate 10, and the outer part of the slide bar 9 is sleeved with a spring 11, and the two ends of the spring 11 are respectively connected to the semicircular plate 10 and the vertical plate 2; the clamping assembly also includes two conductive clips 12 whose middle parts are hinged to the side of the vertical plate 2, and the two conductive clips 12 are symmetrically arranged obliquely. The upper ends of the two conductive clips 12 are used to clamp the pins of the resistor 3, and the lower ends of the two conductive clips 12 are in contact with the arc surface of the semicircular plate 10, and one conductive clip 12 is connected to a wire 14, and the wire 14 is connected to the detection device.

[0031] Specifically, when the top plate 4 moves upward, before the inclined groove 401 contacts the resistor 3, the main shaft 5 drives the cam 2 7 of the clamping assembly to rotate synchronously. At this time, the cam 2 7 drives the flat plate 8 and the slide bar 9 to move downward, the spring 11 is compressed, and the semicircular plate 10 is gradually separated from the lower end of the conductive clip 12. The spring 2 13 provides power to separate the upper ends of the two conductive clips 12 of the clamping assembly, that is, the two conductive clips 12 of the two clamping assemblies release the pins at both ends of the resistor 3 at the same time; when the top plate 4 moves downward, after the resistor 3 is placed in the next adjacent arc groove 201, the spring 11 provides elastic force to move the slide bar 9 upward, and the semicircular plate 10 opens the lower ends of the two conductive clips 12 of the clamping assembly, so that the upper ends of the two conductive clips 12 are brought together, that is, the conductive clips 12 of the two clamping assemblies clamp the pins at both ends of the resistor 3 at the same time, the conductive clips 12 and the wire 14 are connected, and the wire 14 is connected to the detection device, which is convenient for detecting the resistor 3.

[0032] A loading rack 15 is provided on the bottom plate 1 and at the front side of the vertical plate 2. The loading rack 15 is rotatably provided with a driven shaft 16, and a motor 17 is fixedly provided on the loading rack 15. The rotating shaft of the motor 17 is connected to the driven shaft 16. An asynchronous transmission mechanism 18 is provided between the driven shaft 16 and the main shaft 5. The driving wheel of the asynchronous transmission mechanism 18 is fixedly provided on the driven shaft 16, and the driven wheel of the asynchronous transmission mechanism 18 is fixedly provided on the main shaft 5. The diameter of the driving wheel of the asynchronous transmission mechanism 18 is four times the diameter of the driven wheel.

[0033] Specifically, the asynchronous transmission mechanism 18 is composed of a driving wheel, a driven wheel and a transmission belt, and the transmission belt is wound around the driving wheel and the driven wheel. The driving wheel rotates, and the power is transmitted through the transmission belt to drive the driven wheel to rotate, and the speed of the driven wheel is four times that of the driving wheel. The motor 17 drives the driving shaft 16 to rotate, and the power is transmitted through the asynchronous transmission mechanism 18 to drive the main shaft 5 to rotate, and the speed of the main shaft 5 is four times that of the driving shaft 16.

[0034] A loading tray 19 is fixedly provided on the loading rack 15, and the loading tray 19 is located between the two vertical plates 2. Four material openings 1901 for clamping the resistor 3 are evenly arranged on the cylindrical surface of the loading tray 19. A material storage 20 for storing the resistor 3 is provided on the bottom plate 1 and on the side of the loading tray 19.

[0035] An arc guide rod 21 for prying the resistor 3 is provided between the vertical plate 2 and the loading tray 19 , the lower end of the arc guide rod 21 is connected to the upper front side of the vertical plate 2 , and the upper end of the arc guide rod 21 is located below the top of the loading tray 19 .

[0036] Specifically, the moving shaft 16 drives the loading tray 19 to rotate synchronously. When the loading port 1901 of the loading tray 19 is located in the material storage 20, the resistor 3 in the material storage 20 is squeezed into the loading port 1901. When the loading port 1901 with the resistor 3 moves to the top of the loading tray 19, the resistor 3 is located above the upper end of the arc guide rod 21. As the loading tray 19 continues to rotate, the arc guide rod 21 squeezes out the resistor 3 in the loading port 1901, and the resistor 3 slides along the loading port 1901 onto the vertical plate 2 and falls into the first arc groove 201 on the vertical plate 2. The main shaft 5 and the cam 6 rotate one circle, and the top plate 4 makes a reciprocating motion. The resistor 3 on the first arc groove 201 will move to the second arc groove 201. At the same time, the loading tray 19 rotates four times a circle, and a new resistor 3 falls into the first arc groove 201 along the arc guide rod 21, and the loading is repeated.

[0037] A secondary shaft 22 is provided on the two vertical plates 2 and close to the rear side of the vertical plates 2 so as to rotate together. A synchronous transmission mechanism 23 is provided between the secondary shaft 22 and the main shaft 5. The driving wheel and the driven wheel of the synchronous transmission mechanism 23 are respectively installed on the main shaft 5 and the secondary shaft 22, and the driving wheel and the driven wheel of the synchronous transmission mechanism 23 have the same diameter. A cam 6 for driving the top plate 4 to move is provided on the secondary shaft 22 and located between the two vertical plates 2.

[0038] Specifically, the synchronous transmission mechanism 23 is composed of a driving wheel, a driven wheel and a transmission belt. The transmission belt is wound around the driving wheel and the driven wheel. The driving wheel and the driven wheel have the same diameter. When the driving wheel rotates, the power is transmitted through the transmission belt to drive the driven wheel to rotate synchronously. The power is transmitted through the synchronous transmission mechanism 23, and the main shaft 5 drives the secondary shaft 22 to rotate synchronously. Then, the cam 6 on the main shaft 5 and the secondary shaft 22 rotates synchronously, so the top plate 4 is driven to reciprocate more smoothly.

[0039] Two groups of vertical insertion components are provided above the bottom plate 1, and the vertical insertion components include two guide rods 24 vertically arranged above the bottom plate 1, and a slide 25 is slidably provided on the two guide rods 24, and two vertical rotating plates 26 are provided on the slide 25. The lower end of the vertical rotating plate 26 is hinged to the upper end of the connecting rod 27, and the lower end of the connecting rod 27 is hinged to the convex point of the swing plate 28.

[0040] Specifically, the swing plate 28 rotates around the center and transmits power through the connecting rod 27, so that the slide 25 performs reciprocating up and down linear motion along the guide rod 24.

[0041] The centers of the two swing plates 28 of the first group of vertical insertion components are fixed on the main shaft 5, and a cutter 29 is provided in the middle of the slide 25. A top cutting block 30 is provided on the outer side of the vertical plates 2 on both sides and below the cutter 29, and the top cutting block 30 is located below an arc groove 201.

[0042] Specifically, the main shaft 5 drives the center of the first set of swing plates 28 to rotate. When the top plate 4 moves upward, the slide 25 and the cutter 29 rise synchronously to make room for the top plate 4 to lift the resistor 3. When the top plate 4 moves downward, the slide 25 and the cutter 29 descend synchronously, and the two pins of the resistor 3 corresponding to the arc groove 201 are located on the top cutting block 30. The cutter 29 overlaps with the top cutting block 30 to cut off the excess length of the two pins of the resistor 3.

[0043] The centers of the two swing plates 28 of the second set of vertical insertion assemblies are fixed on the secondary shaft 22, and a bending knife 31 is provided in the middle of the slide 25. A bending top block 32 is provided on the outer side of the vertical plates 2 on both sides and below the cutting knife 29, and the cutting top block 30 is located below another arc groove 201.

[0044] Specifically, the secondary shaft 22 drives the center of the second set of swing plates 28 to rotate. When the top plate 4 moves upward, the slide 25 and the bending knife 31 rise synchronously to make room for the top plate 4 to lift the resistor 3. When the top plate 4 moves downward, the slide 25 and the bending knife 31 fall synchronously, and the two pins of the resistor 3 corresponding to the arc groove 201 are located on the bending top block 32. The bending knife 31 overlaps with the bending top block 32, and the two pins of the resistor 3 are bent, which is convenient for further installation of the resistor 3.

[0045] Working principle: put the produced resistor 3 into the material warehouse 20, start the motor 17, the motor 17 drives the dynamic shaft 16 to rotate, and the dynamic shaft 16 drives the loading tray 19 to rotate synchronously. When the loading port 1901 of the loading tray 19 is located in the material warehouse 20, the resistor 3 in the material warehouse 20 is squeezed into the material port 1901. When the material port 1901 with the resistor 3 moves to the top of the loading tray 19, the resistor 3 is located above the upper end of the arc guide rod 21. As the loading tray 19 continues to rotate, the arc guide rod 21 squeezes out the resistor 3 in the material port 1901, and the resistor 3 slides along the material port 1901 to the vertical plate 2 and falls into the first arc groove 201 on the vertical plate 2.

[0046] The power is transmitted through the asynchronous transmission mechanism 18, and the moving shaft 16 drives the main shaft 5 to rotate, and the speed of the main shaft 5 is four times that of the moving shaft 16. The main shaft 5 drives the cam 6 to rotate synchronously, and the cam 6 drives the top plate 4 to reciprocate. When the top plate 4 rises, the inclined groove 401 on the top plate 4 pushes the resistor 3 upward from the arc groove 201. After the resistor 3 leaves the arc groove 201, the resistor 3 slides along the inclined groove 401 to the top of the next adjacent arc groove 201. When the top plate 4 falls, the resistor 3 is placed in the next adjacent arc groove 201, and the inclined groove 401 is separated from the resistor 3. By sliding the top plate 4 back and forth between the two pieces, the resistor 3 can be moved forward in the vertical plate 2 and the arc groove 201 in sequence.

[0047] The main shaft 5 and the cam 6 rotate one circle, and the top plate 4 makes a reciprocating motion. The resistor 3 originally on the first arc groove 201 will move to the second arc groove 201. At the same time, the loading plate 19 rotates one quarter of a circle, and a new resistor 3 falls into the first arc groove 201 along the arc guide rod 21. The above process is repeated for continuous loading.

[0048] When the detection device detects the resistor 3, the spring 11 provides elastic force to make the slide bar 9 and the semicircular plate 10 in the upper position, and the semicircular plate 10 opens the lower ends of the two conductive clips 12 of the clamping assembly to bring the upper ends of the two conductive clips 12 closer together. The spring 2 13 is in a compressed state, that is, the conductive clips 12 of the two clamping assemblies clamp the pins at both ends of the resistor 3 located in the arc groove 201 above them at the same time, the conductive clips 12 and the wire 14 are conductive, and the wire 14 is connected to the detection device, thereby achieving the purpose of the detection device detecting the resistor 3. The main shaft 5 rotates one circle to realize automatic detection of the next resistor 3, and the process is as follows: when the top plate 4 moves upward and before the inclined groove 401 contacts the resistor 3, the main shaft 5 drives the cam 2 7 of the clamping assembly to rotate synchronously. At this time, the cam 2 7 drives the flat plate 8, the slide bar 9 and the semicircular plate 10 to move downward, the spring 11 is compressed, and the semicircular plate 10 and the lower end of the conductive clip 12 are gradually separated. The spring 2 13 provides elastic force to separate the upper ends of the two conductive clips 12 of the clamping assembly, that is, the conductive clips 12 of the two clamping assemblies release the pins at both ends of the resistor 3 at the same time; when the top plate 4 continues to move upward to the upper position, the inclined groove 401 on the top plate 4 pushes the detected resistor 3 upward from the arc groove 201. When the top plate 4 moves downward, the spring 11 provides elastic force to move the slide bar 9 and the semicircular plate 10 upward. Before the semicircular plate 10 contacts the conductive clip 12 again, the detected resistor 3 is placed in the next adjacent arc groove 201, and the next resistor 3 is placed in the arc groove 201 above the conductive clip 12. When the top plate 4 continues to move downward to the lower position, the slide bar 9 and the semicircular plate 10 move upward to the upper position again, and the semicircular plate 10 again opens the lower ends of the two conductive clips 12 of the clamping assembly. Then, the conductive clips 12 of the two clamping assemblies clamp the pins at both ends of the next resistor 3 at the same time, and the detection device can complete the detection of the next resistor 3.

[0049] The main shaft 5 drives the center of the first set of swing plates 28 to rotate, so that the slide 25 moves back and forth along the guide rod 24. When the top plate 4 moves upward, the slide 25 and the cutter 29 rise synchronously to make room for the top plate 4 to lift the resistor 3. When the top plate 4 moves downward, the slide 25 and the cutter 29 fall synchronously, and the two pins of the resistor 3 corresponding to the arc groove 201 are located on the top cutting block 30, and the cutter 29 overlaps with the top cutting block 30 to cut off the excess length of the two pins of the resistor 3.

[0050] The secondary shaft 22 drives the center of the second set of swing plates 28 to rotate, so that the slide 25 moves back and forth along the guide rod 24. When the top plate 4 moves upward, the slide 25 rises synchronously with the bending knife 31 to make room for the top plate 4 to lift the resistor 3. When the top plate 4 moves downward, the slide 25 descends synchronously with the bending knife 31, and the two pins of the resistor 3 corresponding to the arc groove 201 are located on the bending top block 32, and the bending knife 31 overlaps with the bending top block 32, bending the two pins of the resistor 3, which is convenient for further installation of the resistor 3.

[0051] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
