Description

Technical Field

[0001] The present invention relates to the field of resistance testing technology, and in particular to a resistance testing fixture, system and method. Background Art

[0002] At present, the electrical properties of conductive tapes are mainly evaluated and managed scientifically, effectively and reasonably by testing resistance. Resistance measuring instruments are generally measured by test leads like a multimeter. However, since conductive tapes are prone to wrinkles and stacking, the resistance errors of multiple measurements are large. Even if the measured resistance values ​​are averaged, accurate measurement results cannot be obtained. In addition, dust and other metal particles attached to the surface of the conductive tape will cause poor contact between the test leads and the conductive tape, resulting in large errors. For this reason, we have introduced a resistance test fixture, system and method. Summary of the invention

[0003] The object of the present invention is to provide a resistance testing fixture, system and method to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

A raised belt is provided in the middle of the conveyor belt, and the side of the rubber box is connected to the connecting cylinder through a hose;

[0008] The limit plate on the side of the bracket passes through the vertical slide groove extending out of the side of the U-shaped seat and is connected to a clamping mechanism, which includes a support rod fixed to the upper end of the limit plate, a top plate connected to the top of the support rod, abutment plates connected to both sides of the lower end of the top plate, and a clamping seat located between the two sets of abutment plates;

[0009] After the lifting conveying mechanism rises, the top of the raised belt extends out from between the two sets of placement plates, and under the rotation of the conveyor belt, the raised belt transports the conductive tape forward;

[0010] After the lifting conveying mechanism descends, the raised belt breaks away from the contact with the conductive tape. At this time, the conductive tape is located on the upper ends of the two sets of placement plates. The rubber box is pressurized to press the air into the pressure roller through the hose until the air blows to the upper end surface of the conductive tape through the through slot.

[0011] At the same time, the clamping mechanism moves downward, and the bottom of the abutment plate is pressed on the top of the abutment mechanism. The abutment mechanism presses the two sets of pressure rollers down to the upper end surface of the conductive tape, while the pressure rollers roll on the upper end surface of the conductive tape until the clamping seat presses the conductive tape onto the two sets of placement plates.

[0012] Preferably, the bracket includes a mounting frame with a driving roller and a driven roller mounted at both ends and a lifting plate fixed at the bottom of the mounting frame, and the limit plate is arranged at the front and rear parts of the side edge of the lifting plate;

[0013] A support roller located between the driving roller and the driven roller is also installed in the mounting frame, and the driving roller, the driven roller and the support roller are located in the conveyor belt;

[0014] A motor for driving the driving roller to rotate is also installed on the side of the mounting frame, and an electric telescopic rod is installed inside the U-shaped seat, and a piston rod at the output end of the top of the electric telescopic rod is connected to the middle part of the lower end of the lifting plate.

[0016] Preferably, a limiting vertical groove is provided on the side wall of the notch in the middle of the U-shaped seat, and the sliding protrusion on the side of the connecting seat is slidably connected in the corresponding limiting vertical groove.

[0017] Preferably, the abutment mechanism comprises two groups of front and rear sleeves, a connecting arm connected to the top of the sleeve, and an abutment seat movably connected to the top of the connecting arm through a pin, and a tension spring connected to the upper part between the two groups of front and rear connecting arms;

[0019] Preferably, a vertical plate is provided in the middle of the upper end of the connecting seat, a vertical rectangular groove is provided on the vertical plate, a limit block is provided at the top of the inner side of the abutment seat, and the limit block is slidably connected in the vertical rectangular groove.

[0020] Preferably, the abutment plate is located on the top of the abutment seat, and in an initial state, the pressing seat is located directly above the two groups of front and rear pressing rollers.

[0021] The present invention also provides a test system for a resistance test fixture, comprising the resistance test fixture.

[0022] The present invention also provides a test method for a resistance test fixture, which specifically comprises the following steps:

[0023] S1. Place the conductive tape on the upper end of the placement plate, and the lifting conveyor mechanism rises so that the top of the raised belt extends out from between the two sets of placement plates. Under the rotation of the conveyor belt, the raised belt transports the conductive tape forward;

[0024] S2, the lifting and conveying mechanism descends so that the raised belt is out of contact with the conductive tape, and the rubber box is pressurized to blow air toward the upper surface of the conductive tape through the through slot;

[0025] S3. The lifting and conveying mechanism drives the pressing mechanism to move downward, and the bottom of the abutment plate is pressed on the top of the abutment mechanism, so that the two sets of pressure rollers are pressed down to the upper end surface of the conductive tape, and the pressure rollers roll on the upper end surface of the conductive tape until the pressing seat presses the conductive tape onto the two sets of placement plates.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: after the lifting and conveying mechanism of the present invention rises, the top of the raised belt extends out from between the two groups of placement plates, and under the rotation of the conveyor belt, the raised belt transports the conductive tape forward, so that the position of the conductive tape can be continuously adjusted to measure the resistance of different positions of the conductive tape; after the lifting and conveying mechanism descends, the rubber box is pressurized to press air into the pressure roller through the hose until the air is blown to the upper end surface of the conductive tape through the through groove, so that the upper end surface of the conductive tape can be kept clean to avoid dust adhesion and inaccurate resistance measurement.

[0027] At the same time, the clamping mechanism moves downward, and the bottom of the abutment plate is pressed on the top of the abutment mechanism. The abutment mechanism presses the two sets of pressure rollers down to the upper end surface of the conductive tape, and the pressure rollers roll on the upper end surface of the conductive tape until the clamping seat presses the conductive tape onto the two sets of placement plates. This ensures that the conductive tape is flat and prevents the conductive tape from stacking, causing inaccurate resistance measurement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-11 , the present invention provides a technical solution:

[0042] A resistance test fixture, comprising a U-shaped seat 1, a placement plate 102 for placing a conductive tape is provided on the upper inner wall of the U-shaped seat 1, a rolling mechanism 3 is provided between the notches in the middle of the U-shaped seat 1, and the rolling mechanism 3 comprises a connecting seat 305 provided in the notch in the middle of the U-shaped seat 1 and two front and rear groups of rollers 301 movably connected between the two groups of connecting seats 305;

[0043] The bottom of the notch in the middle of the U-shaped seat 1 is provided with a horizontal plate 103 extending outwards. Fig.11 As shown, the bottom of the connection seat 305 is connected to the upper end of the horizontal plate 103 through a spring 307, and the waisted round holes 308 are symmetrically arranged on the connection seat 305. In this way, the elastic force of the spring 307 on the connection seat 305 makes the connection seat 305 at the highest position in the initial state, so that the front and rear two sets of rollers 301 are also at the highest position, and the distance between the front and rear two sets of rollers 301 and the placement plate 102 is the largest, which is convenient for placing the conductive tape;

[0044] When placing the conductive tape, it is necessary to first pull out one end of the cylindrical base paper and cut it off, and then place the cut section of the conductive tape flat on the upper ends of the two sets of placement plates 102.

[0045] A limiting vertical groove 104 is provided on the notch side wall in the middle of the U-shaped seat 1, and the sliding protrusion 306 on the side of the connecting seat 305 is slidably connected in the corresponding limiting vertical groove 104. Such a setting can ensure that the connecting seat 305 moves up and down in a vertical state, and prevent the position of the connecting seat 305 from being offset when it moves up and down.

[0046] The surface of the pressure roller 301 is evenly provided with through grooves 302. Both ends of the pressure roller 301 are connected with connecting tubes 303 that are connected with the internal cavity of the pressure roller 301. The connecting tubes 303 extend through the waist-shaped holes 308 on the connecting seat 305, and the ends of the two adjacent groups of connecting tubes 303 are connected with abutment mechanisms 311.

[0047] like Figure 4 , 5 , 6, 8 and 10 The abutment mechanism 311 comprises two sets of front and rear sleeves 3112, a connecting arm 3111 connected to the top of the sleeve 3112, and an abutment seat 3115 movably connected to the top of the connecting arm 3111 through a pin 3144, and a tension spring 3113 connected to the upper part between the front and rear sets of connecting arms 3111;

[0048] The connecting tube 303 extends out through the oval hole 308 and is connected to the corresponding sleeve tube 3112. The hose 203 is connected to the sleeve tube 3112. The connecting tube 303 is also sleeved with a sealing gasket located inside the sleeve tube 3112, so that when the pressure roller 301 drives the connecting tube 303 to roll, the connecting tube 303 can rotate relative to the sleeve tube 3112, and the sealing gasket is used to achieve the sealing of the connection between the connecting tube 303 and the sleeve tube 3112, ensuring that there is no air leakage at the connection between the two. Figure 6 As shown, the sleeve 3112 is located outside the oval hole 308 to prevent the connecting tube 303 from being separated from the oval hole 308 .

[0049] A circular hole 304 is provided inside the connecting cylinder 303 and communicates with the inner cavity of the pressing roller 301;

[0050] A vertical plate 310 is provided at the middle of the upper end of the connecting seat 305, a vertical rectangular groove 309 is provided on the vertical plate 310, and a limit block 3116 is provided at the inner top of the abutting seat 3115, and the limit block 3116 is slidably connected in the vertical rectangular groove 309. Such a setting can ensure that the abutting seat 3115 moves up and down in a vertical state, and prevent the position of the abutting seat 3115 from being offset when it moves up and down.

[0051] like Figure 8 and 11 As shown, the abutment plate 404 is located on the top of the abutment seat 3115 . In the initial state, the pressing seat 405 is located directly above the front and rear groups of pressing rollers 301 .

[0052] A lifting and conveying mechanism 2 is provided inside the U-shaped seat 1. Figure 3 As shown, the lifting and conveying mechanism 2 includes a bracket for installing a conveyor belt 207 and two sets of rubber boxes 202 connected to the bottom of the bracket;

[0053] A raised belt 208 is provided in the middle of the conveyor belt 207, and the side of the rubber box 202 is connected to the connecting tube 303 through the hose 203;

[0054] One end of the hose 203 is connected to the side of the rubber box 202 , and the other end thereof extends through the U-shaped seat 1 and is connected to the corresponding socket 3112 .

[0055] An air inlet pipe is also provided at the bottom of the side of the rubber box 202, and a one-way valve is provided on the air inlet pipe. When the lifting plate 204 of the bracket descends to cause the rubber box 202 to be deformed and compressed, the one-way valve closes the connection between the air inlet pipe and the rubber box 202, so that the air inside the rubber box 202 is discharged through the hose 203;

[0056] When the lifting plate 204 rises to make the rubber box 202 rebound and expand to reset, the one-way valve opens, so that the air intake pipe is connected to the rubber box 202, and the outside air enters the rubber box 202 through the air intake pipe, so that the inside of the rubber box 202 is repeatedly filled with air.

[0057] The bracket includes a mounting frame 206 with a driving roller 211 and a driven roller 209 mounted at both ends, and a lifting plate 204 fixed at the bottom of the mounting frame 206, and a limiting plate 205 is arranged at the front and rear parts of the side of the lifting plate 204;

[0058] A support roller 210 is also installed in the mounting frame 206 and is located between the driving roller 211 and the driven roller 209. The driving roller 211, the driven roller 209 and the support roller 210 are located in the conveyor belt 207. When the conveyor belt 207 rotates, the support roller 210 can provide support for the conveyor belt 207, and the driving roller 211 and the driven roller 209 tension the front and rear ends of the conveyor belt 207 so that the top of the raised belt 208 on the conveyor belt 207 is in a horizontal state.

[0059] A motor 212 for driving the driving roller 211 to rotate is also installed on the side of the mounting frame 206. The PLC controller controls the motor 212 to work, so that the driving roller 211 drives the conveyor belt 207 to rotate;

[0060] An electric telescopic rod 201 is installed inside the U-shaped seat 1, and the piston rod at the top output end of the electric telescopic rod 201 is connected to the middle of the lower end of the lifting plate 204. The PLC controller controls the operation of the electric telescopic rod 201, and the conveyor belt 207 and the overall height of the bracket are raised or lowered by extending or retracting the piston rod;

[0061] The limiting plate 205 on the side of the bracket passes through the vertical slide groove 101 extending out of the side of the U-shaped seat 1 and is connected to a clamping mechanism 4, which includes a support rod 403 fixed to the upper end of the limiting plate 205, a top plate 401 connected to the top of the support rod 403, abutment plates 404 connected to both sides of the lower end of the top plate 401, and a clamping seat 405 located between the two sets of abutment plates 404;

[0062] After the lifting conveying mechanism 2 rises, the top of the raised belt 208 extends out from between the two sets of placement plates 102, and under the rotation of the conveying belt 207, the raised belt 208 transports the conductive tape forward;

[0063] After the lifting and conveying mechanism 2 is lowered, the raised belt 208 is out of contact with the conductive tape. At this time, the conductive tape is located on the upper ends of the two sets of placement plates 102. The rubber box 202 is pressurized to press the air into the pressure roller 301 through the hose 203 until the air is blown toward the upper end surface of the conductive tape through the through slot 302.

[0064] At the same time, the clamping mechanism 4 moves downward, and the bottom of the abutment plate 404 is pressed on the top of the abutment mechanism 311. The abutment mechanism 311 presses the two sets of pressure rollers 301 down to the upper end surface of the conductive tape, while the pressure rollers 301 roll on the upper end surface of the conductive tape until the clamping seat 405 presses the conductive tape onto the two sets of placement plates 102.

[0065] The present invention also provides a test system of a resistance test fixture, including the resistance test fixture. The test system of the resistance test fixture includes a display 402 installed on the top of a top plate 401, the display 402 has a built-in PLC controller, and the PLC controller is electrically connected to the motor 212 and the electric telescopic rod 201 through a wire.

[0066] The present invention also provides a test method for a resistance test fixture, which specifically comprises the following steps:

[0067] S1, place the conductive tape on the upper end of the placement plate 102, the lifting conveying mechanism 2 rises so that the top of the raised belt 208 extends out from between the two sets of placement plates 102, and the raised belt 208 transports the conductive tape forward under the rotation of the conveyor belt 207;

[0068] S2, the lifting and conveying mechanism 2 is lowered so that the raised belt 208 is out of contact with the conductive tape, and the rubber box 202 is pressurized to blow air toward the upper end surface of the conductive tape through the through slot 302;

[0069] S3, the lifting and conveying mechanism 2 drives the clamping mechanism 4 to move downward, and the bottom of the abutment plate 404 is pressed on the top of the abutment mechanism 311, so that the two sets of pressure rollers 301 are pressed down to the upper end surface of the conductive tape, and the pressure rollers 301 roll on the upper end surface of the conductive tape until the clamping seat 405 presses the conductive tape onto the two sets of placement plates 102.

[0070] Specifically, when in use, the conductive tape is placed on the upper end of the placement plate 102, and the PLC controller controls the electric telescopic rod 201 to work, and the piston rod extends to make the conveyor belt 207 and the overall height of the bracket rise until the top of the raised belt 208 extends from between the two sets of placement plates 102;

[0071] The PLC controller controls the motor 212 to work, so that the driving roller 211 drives the conveyor belt 207 to rotate. Under the rotation of the conveyor belt 207, the raised belt 208 transports the conductive tape forward;

[0072] Subsequently, the PLC controller controls the electric telescopic rod 201 to work, and the piston rod retracts, so that the conveyor belt 207 and the bracket are lowered as a whole, so that the raised belt 208 is out of contact with the conductive tape, and the raised belt 208 no longer transports the conductive tape forward;

[0073] At this time, the rubber box 202 is pressed down by the lifting plate 204, and the rubber box 202 is deformed and compressed, so that the air inside the rubber box 202 enters the sleeve 3112 through the hose 203, and then enters the round hole 304 from the sleeve 3112, and finally enters the inside of the pressing roller 301, until it is blown to the upper surface of the conductive tape through the through groove 302, and the dust on the upper surface of the conductive tape is blown off, so that the upper surface of the conductive tape is in a clean state;

[0074] The lifting plate 204 drives the pressing mechanism 4 to move downward, and the bottom of the abutting plate 404 presses against the abutting seat 3115 at the top of the abutting mechanism 311. At this time, the connecting seat 305 is pressed by the pressure from the abutting plate 404, and the connecting seat 305 moves downward, so that the spring 307 is in a compressed state, until the pressure roller 301 on the connecting seat 305 is pressed against the upper end surface of the conductive tape;

[0075] Then, the abutment seat 3115 moves downward relative to the vertical plate 310, so that the front and rear groups of connecting arms 3111 are in an open state. At this time, due to the opening of the front and rear groups of connecting arms 3111, the connecting cylinders 303 on the front and rear groups of pressing rollers 301 slide along the waist holes 308, and the front pressing roller 301 rolls forward along the upper end surface of the conductive tape, and the rear pressing roller 301 rolls backward along the upper end surface of the conductive tape, and the conductive tape is pressed flatly on the two groups of placement plates 102, until the pressing seat 405 presses the conductive tape flatly on the two groups of placement plates 102;

[0076] Then, the test probes of the resistance measuring instrument are connected to the two ends of the flattened part of the conductive tape to measure the resistance, and the measured data is displayed on the display 402;

[0077] Finally, repeat the above steps to move the conductive tape forward a certain distance. After the conductive tape is flattened again, measure the resistance of the flattened part of the conductive tape. By measuring several groups and calculating the average value, the resistance of the conductive tape can be accurately measured.

[0078] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The lifting and conveying mechanism drives the pressing mechanism to move downward, and the bottom of the abutment plate is pressed on the top of the abutment mechanism, so that the two sets of pressure rollers are pressed down to the upper end surface of the conductive tape, and the pressure rollers roll on the upper end surface of the conductive tape until the pressing seat presses the conductive tape onto the two sets of placement plates.
