[0026] like Figure 1-4 As shown, the present invention mainly processes the heating tube, and puts on the magnetic beads at the connecting end of the heating tube. An automatic glue dispensing, magnetic bead insertion, resistance and withstand voltage measurement integrated machine comprises a frame 1, on which a control terminal 2, a material discharge mechanism 3, a test resistance mechanism 4, a withstand voltage test mechanism 5, a glue dispensing rotation mechanism 6, a magnetic bead insertion mechanism 7, a material clamping mechanism 8, a vibration plate 9 and a length adjustment mechanism are arranged. The test resistance mechanism 4 is arranged above the withstand voltage test mechanism 5, and the test resistance mechanism 4 and the withstand voltage test mechanism 5 are arranged on both sides of the dispensing mechanism 3, respectively. The dispensing mechanism 3, the test resistance mechanism 4, the withstand voltage test mechanism 5, the glue dispensing rotation mechanism 6, the magnetic bead insertion mechanism 7 and the vibration plate 9 are all arranged on the length adjustment mechanism, and a defective product slot 13 is arranged below the withstand voltage test mechanism 5, and a material discharge guide rod 14 is arranged on the frame 1. The heating tubes are placed into the discharge mechanism one by one manually or by a robot, and the resistance and withstand voltage tests are carried out in turn by the resistance test mechanism and the withstand voltage test mechanism. Unqualified products are directly transported to the unqualified product channel; qualified heating tubes enter the glue dispensing rotating mechanism for gluing, and finally enter the magnetic bead threading mechanism to thread the magnetic beads transported from the vibration plate onto the heating tubes. After the processing is completed, the heating tubes can be transported to the designated position from the unloading guide rod 14. For example, a storage box is set at the position corresponding to the unloading guide rod, and the processed heating tubes can be directly transported to the storage box. Similarly, the processed heating tubes can be taken out from the clamping mechanism manually or by a robot. Of course, an electric box can be set in the frame to provide the necessary power supply for each mechanism. The control terminal is a computer, and the processing parameters can be input and the working status can be observed through the display.

[0027] The length adjustment mechanism includes an adjustment guide shaft 10 and an adjustment plate 11. The adjustment guide shaft 10 is fixedly mounted on the frame 1. An adjustment slider is movably mounted on the adjustment guide shaft 10. The adjustment plate 11 is mounted on the adjustment slider. Two adjustment plates are provided, which are respectively located on both sides of the frame. The adjustment plates can move along the adjustment guide shaft so that the two adjustment plates are close to or away from each other, so as to meet the processing requirements of heating tubes of different lengths.

[0028] Focus on reference Figure 2As shown, the discharge mechanism 3 includes two discharge support frames 301, an adjusting motor 302, a feeding chute 303 and a screening cylinder 304. One discharge support frame 301 is installed on an adjusting plate 11. The output shaft of the adjusting motor 302 is equipped with a screw rod 305. The screw rod 305 passes through the two discharge support frames 301 and is installed and connected to the discharge support frames 301 through bearings. The adjusting motor 302 is installed on the side of one of the discharge support frames 301. The feeding chute 303 is arranged on the upper part of the discharge support frame 301. The unqualified product trough 13 is arranged at the lower part of the material discharging support frame 301, and a falling channel 306 is arranged in the material discharging support frame 301. The screening cylinder 304 is installed on the side of the material discharging support frame 301. The driving shaft of the screening cylinder 304 is connected with a receiving rod 307 inclined toward the unqualified product trough 13. The receiving rod 307 is located below the falling channel 306. The receiving rod 307 is used to carry the heating tube 12 dropped from the falling channel 306 and transfer it to the unqualified product trough 13. The material discharging support frame 301 is provided with an induction switch 308. When the adjustment motor 302 is set to rotate forward, the two material discharging support frames 301 are close to each other, and when the adjustment motor is reversed, the two material discharging support frames are far away from each other. When the adjustment motor drives the screw rod to rotate forward, it will drive the two material discharging support frames to approach each other, and the material discharging support frame is connected to the adjustment plate, and the adjustment plate 11 will move along the adjustment guide shaft 10, so as to realize the smooth approach of the two material discharging support frames 301. By adjusting the distance between the two material discharging support frames, the processing requirements of heating tubes of different lengths can be met. The feeding chute 303 is tilted from top to bottom from the upper part of the material discharging support frame 301 and is connected to the falling channel 306. The heating tube 12 placed in the feeding chute 303 will automatically slide into the falling channel 306. The screening cylinder 304 drives the receiving rod 307 to move forward and backward. When the heating tube 12 is detected as a defective product, the screening cylinder 304 drives the receiving rod 307 to move to the bottom of the falling channel 306. The heating tube 12 falling from the falling channel 306 will fall onto the receiving rod 307, and the receiving rod 307 is tilted toward the defective product chute 13. Therefore, the heating tube on the receiving rod will automatically slide into the defective product chute. When the qualified heating tube needs to fall from the falling channel, the screening cylinder drives the receiving rod to move outward, which will not block the falling channel, so that the heating tube enters the next process.

[0029] The material discharging support frame 301 is provided with a material blocking cylinder 309, and the driving shaft of the material blocking cylinder 309 is equipped with a material blocking rod 310, which extends into the falling channel 306. The material blocking cylinder 309 drives the material blocking rod 310 to extend into the falling channel 306 or to detach from the falling channel 306. The material blocking rod 310 is located above the test resistor mechanism 4. When the heating tube in the feeding channel needs to fall, the material blocking rod is retracted from the falling channel. At this time, a heating tube falls downward, and then the material blocking cylinder drives the material blocking rod to extend into the falling channel. Other heating tubes in the feeding channel are blocked by the material blocking rod and will not fall, thereby avoiding the problem of heating tubes being piled up and unable to be handled in time.

[0030] The unloading support frame 301 is provided with a positioning cylinder 311, and the driving shaft of the positioning cylinder 311 is connected with a positioning block 312, and the positioning block 312 extends to the falling channel 306. The positioning block can be provided with an arc groove surface to better contact the heating pipe. Two positioning cylinders can be provided, one positioning cylinder corresponds to the test resistance mechanism, and the other positioning cylinder corresponds to the test pressure resistance mechanism, so that the heating pipe is kept fixed at the corresponding position.

[0031] The resistance testing mechanism 4 includes a resistance testing cylinder 41 and a resistance testing device 42. The resistance testing cylinder 41 is mounted on the side of the material discharging support frame 301, and the driving shaft of the resistance testing cylinder 41 is connected to the resistance testing device 42. The resistance testing cylinder drives the resistance testing device to move so as to contact the electrode end on the heating tube, thereby testing the resistance.

[0032] The pressure-resistant testing mechanism 5 comprises a pressure-resistant testing cylinder 51, which is mounted on the side of the material discharging support frame 301, and a driving shaft of the pressure-resistant testing cylinder 51 is connected to a pressure-resistant testing rod 52. The pressure-resistant testing cylinder drives the pressure-resistant testing rod to move so as to abut against the electrode end of the heating tube, thereby performing a pressure-resistant testing of the heating tube.

[0033] Multiple induction switches are provided, at least one of which is provided at the corresponding test resistance mechanism to detect whether there is a heating tube at the test resistance position; at least one is provided at the corresponding test withstand voltage mechanism to detect whether there is a heating tube at the test withstand voltage position, thereby achieving accurate control.

[0034] Focus on reference Figure 3As shown, the clamping mechanism 8 includes a clamping bottom plate 81, a fixing block 82 with a V-shaped groove, a clamping push-out cylinder 83, a clamping lifting cylinder 84 and a clamping pneumatic clamp 85. A guide rail 87 is provided on the clamping bottom plate 81, a slider 88 is provided on the guide rail 87, the clamping push-out cylinder 83 is mounted on the clamping bottom plate 86, the clamping lifting cylinder 84 is mounted on the slider 88, the driving shaft of the clamping push-out cylinder 83 is connected to the slider 88, the driving shaft of the clamping lifting cylinder 84 is mounted with a bearing plate 86, and the clamping pneumatic clamp 85 is mounted on the side of the bearing plate 86. The clamping bottom plate 81 is installed between the two adjustment plates 11, the bottom surface of the clamping bottom plate is movably sleeved on the adjustment guide shaft, the fixing block is installed on the adjustment plate, the same number of fixing blocks are symmetrically arranged on the two adjustment plates, and the two ends of the heating pipe are placed on the corresponding fixing blocks. The clamping and pushing cylinder, guide rail and adjusting guide shaft are arranged in a vertical direction. The clamping and pushing cylinder drives the carrier plate to move along the guide rail, and then drives the heating tube to reach each processing station in turn to complete the gluing and magnetic bead threading. There are several pneumatic clamps on both sides of the carrier plate, so that the magnetic bead threading process can be carried out continuously to improve efficiency.

[0035] Focus on reference Figure 4 As shown, the dispensing rotating mechanism 6 includes a dispensing pinch wheel assembly, a glue tank 61, a dispensing device 62, a rotating wheel 63 and a rotating motor 64. A rotating wheel bracket is installed on the adjusting plate 11. The rotating wheel 63 is installed on the rotating wheel bracket through a rotating shaft. The rotating shaft is connected to the driving shaft of the rotating motor 64 through a belt assembly. The rotating wheel 63 is driven to rotate by the rotating motor 64. A dispensing bracket 65 and a clamping bracket 66 are installed on the adjusting plate 11. The dispensing device 61 is installed on the dispensing bracket 65. The dispensing pinch wheel assembly includes a dispensing pinch wheel 67 and a dispensing pinch cylinder 68. The driving shaft of the dispensing pinch cylinder 68 is connected to a dispensing block 69. The dispensing pinch wheel 67 is installed in the dispensing block 69 through an axis. The dispensing pinch cylinder 68 and the glue tank 61 are installed on the clamping bracket 66. The dispensing pinch wheel 67 is located directly above the rotating wheel 63. The glue tank 61 is filled with glue. The glue dispensing and pressing cylinder 68 drives the glue dispensing and pressing wheel 67 to move downward, thereby pressing the rotating wheel 63 to press the heating tube 12. Two rotating wheels are provided and are connected to the rotating motor through a belt assembly. The rotating motor drives the two rotating wheels to rotate at the same time. A lower recess is formed between the two rotating wheels to facilitate the rotation of the heating tube, and jointly drive the heating tube to rotate to achieve all-round glue application. The surface of the glue dispensing and pressing wheel is a rubber surface, which will not cause damage to the heating tube when pressing the heating tube. The glue dispenser can be set at an angle, and its setting angle is determined according to actual needs. The glue dispenser is connected to the glue tank, and the glue in the glue tank is input into the glue dispenser.

[0036] Focus on reference Figure 4As shown, the magnetic bead threading mechanism 7 includes a magnetic bead pneumatic clamp 71, a magnetic bead threading stroke adjustment cylinder 72, a magnetic bead threading clamping wheel 73 and a magnetic bead threading clamping cylinder 74. The driving shaft of the magnetic bead threading stroke adjustment cylinder 72 is equipped with a stroke block 75. The magnetic bead pneumatic clamp 71 is installed on the stroke block 75. The vibration plate 9 has a conveying groove 15, and the conveying groove 15 extends to the side connected to the magnetic bead cylinder clamp 71. A clamping plate 16 is provided on one side of the conveying groove 15, and the clamping plate 16 is connected to the clamping cylinder 17. The magnetic beads are placed in the vibration plate, and the vibration plate sends the magnetic beads out through vibration, and transports them from the conveying groove to the magnetic bead pneumatic clamp. The magnetic bead pneumatic clamp clamps the magnetic beads, and the magnetic bead threading clamping cylinder drives the magnetic bead threading clamping wheel to move down and press the fixed block to keep the heating tube fixed, so as to keep the heating tube stable during the process of threading the magnetic beads. The magnetic bead threading stroke adjustment cylinder drives the stroke block to move, and then drives the magnetic bead pneumatic clamp to move toward the heating tube, threading the magnetic beads onto the electrode of the heating tube, and then the magnetic bead pneumatic clamp opens, and the magnetic bead threading stroke adjustment cylinder drives the magnetic bead pneumatic clamp to reset, completing the magnetic bead threading operation.

[0037] Two adjustment plates are provided, each of which is provided with a vibration plate, and the electrodes at both ends of the hair can be threaded with magnetic beads at the same time. Each mechanism is symmetrically provided.

[0038] In addition, telescopic support feet can be set on the bottom of the rack to facilitate height adjustment and leveling.

[0039] Specific work:

[0040] According to the length of the heating tube, the spacing between the two material discharging support frames is adjusted by adjusting the motor.

[0041] The heating tube 12 is placed in the feeding channel 30. Initially, the blocking cylinder 309 drives the blocking rod 310 to extend into the falling channel 306 to stop the heating tube 12 from falling. After starting work, the blocking rod 310 retracts and disengages from the falling channel 306, and first slides down a heating tube 12, and then the blocking rod 310 extends into the falling channel 306 to block it. The heating tube 12 first reaches the position of the test resistance mechanism 4, and the positioning cylinder 311 extends the positioning block 312 to fix the heating tube 12 to keep it stable. The test resistance cylinder 41 drives the resistance tester 42 to contact the electrode of the heating tube 12 to complete the resistance test. The positioning cylinder returns again, and the heating tube 12 falls again to the test withstand voltage mechanism 5, and the positioning cylinder at the corresponding position is used to position and hold the position fixed, and the withstand voltage test cylinder 51 drives the withstand voltage test rod 52 to press against the electrode of the heating tube 12, and transmits the test data to the control terminal. If the heating tube is found to be unqualified after the resistance test or the withstand voltage test, the screening cylinder drives the receiving rod to move to the falling channel, and the unqualified heating tube falls onto the receiving rod and slides from the receiving rod to the unqualified product channel to complete the unqualified product screening. If the resistance and withstand voltage tests are qualified, the screening cylinder drives the receiving rod to move outward to ensure that the normal falling of the heating tube is not disturbed.

[0042] The material clamping and lifting cylinder 84 in the material clamping mechanism 8 pushes up the bearing plate 86, the material clamping pneumatic clamping claw 85 opens and clamps the heating tube 12 and then closes, the material clamping and lifting cylinder 84 moves down until the two ends of the heating tube 12 are just placed in the V-grooves of the fixed block 82, and the material clamping and pushing cylinder 83 drives the bearing plate 86 to move, and the material clamping and lifting cylinder 84 needs to push up a short distance to make the heating tube 12 disengage from the V-groove of the fixed block 82, and then move to the position of the dispensing rotating mechanism 6. When the heating tube moves to the rotating wheel 63, the dispensing pressing wheel 67 is driven by the dispensing pressing cylinder 68 to move down and press the heating tube 12, and the dispensing device 62 sprays glue to perform the dispensing operation. The rotating motor 64 drives the rotating wheel 63 to rotate, drives the heating tube to rotate, and completes 360-degree dispensing. During the dispensing process, the pneumatic clamping jaws for clamping materials remain in an open state and do not affect the rotation of the heating tube. Through the compression of the clamping wheel, the clamping wheel and the heating tube are in circular contact, so the rotation of the heating tube is not affected.

[0043] After the dispensing is completed, the material pushing cylinder 83 continues to drive the carrier plate 86 to move, so that the heating tube that has completed the dispensing is moved to the position of the magnetic bead insertion mechanism 7. The magnetic beads delivered from the vibration plate 9 enter the magnetic bead pneumatic clamp 71 and are clamped. The magnetic bead insertion stroke adjustment cylinder 72 drives the magnetic bead pneumatic clamp 71 to move toward the heating tube 12. Since the heating tube 12 is pressed by the magnetic bead insertion pressing wheel 73 and remains motionless, the magnetic beads in the magnetic bead pneumatic clamp can be smoothly inserted onto the electrode of the heating tube, and then the magnetic bead pneumatic clamp opens and moves back to the initial position, waiting for the next operation.

[0044] Finally, the heating tube that has completed resistance test, withstand voltage test, glue dispensing and magnetic beads is taken out. This cycle continues.
