The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] like Figure 1 and Figure 2 As shown, the present invention discloses a metal alloy resistance detection, dust removal, and tape braiding device 10, which includes: a feeding mechanism 100, a pre-inspection mechanism 200, a full inspection mechanism 300, and a tape braiding mechanism 400.

[0039] like Figure 3 As shown, the pre-inspection mechanism 200 includes: a sub-turntable 210, a CCD front detection device 220, a front ion dust removal device 230, and a pre-inspection bad removal device 240. The CCD front detection device 220, the front ion dust removal device 230, and the pre-inspection bad removal device 240 are sequentially arranged around the sub-turntable 210. The sub-turntable 210 drives the metal alloy resistor 20 to be detected to rotate, the CCD front detection device 220 is used to detect the front appearance and size of the metal alloy resistor 20, the front ion dust removal device 230 is used to perform ion blowing dust removal on the front of the metal alloy resistor 20, and the pre-inspection bad removal device 240 is used to remove the metal alloy resistor 20 with poor appearance and size detection.

[0040] like Figure 4 and Figure 5As shown, the full inspection mechanism 300 includes: a main turntable 310, a CCD bottom surface detection device 320, a CCD flatness detection device 330, a resistance measuring device 340, a bottom surface ion dust removal device 350, and a full inspection defect removal device 360. The CCD bottom surface detection device 320, the CCD flatness detection device 330, the resistance measuring device 340, the bottom surface ion dust removal device 350, and the full inspection defect removal device 360 ​​are sequentially arranged around the main turntable 310. The main turntable 310 drives the metal alloy resistor 20 to be inspected to perform lifting and rotating movements. The CCD bottom surface detection device 320 is used to detect the appearance and size of the bottom surface of the metal alloy resistor 20. The CCD flatness detection device 330 is used to detect the flatness of the metal alloy resistor 20. The resistance measuring device 340 is used to measure the resistance value of the metal alloy resistor 20. The bottom surface ion dust removal device 350 is used to perform ion blowing dust removal on the bottom surface of the metal alloy resistor 20. The full inspection defect removal device 360 ​​is used to remove the metal alloy resistor 20 with poor appearance and size inspection.

[0041] like Figure 3 As shown, the loading mechanism 100 is used to load the metal alloy resistor 20 onto the secondary turntable 210 .

[0042] like Figure 4 and Figure 5 As shown, the main turntable 310 is used to pick up the metal alloy resistor 20 from the auxiliary turntable 210, and it passes through the CCD bottom surface detection device 320, the CCD flatness detection device 330, the resistance measurement device 340, the bottom surface ion dust removal device 350, and the full inspection defect removal device 360 ​​in sequence, and finally reaches the braiding mechanism 400.

[0043] On the one hand, considering that the metal alloy resistor 20 has a front side and a bottom side, and both the front side and the bottom side of the metal alloy resistor 20 need to be measured for appearance and size, as well as related electrical performance tests, if a "flipping device" is provided to flip the metal alloy resistor 20, this will increase the complexity of the device and the probability of error is relatively high; therefore, before the device is developed, it is necessary to consider how to detect the front and back sides of the metal alloy resistor 20 without flipping the metal alloy resistor 20, so as to increase the stability of the device operation, which is a technical problem that needs to be solved;

[0044] On the other hand, since it is necessary to inspect the front and back sides of the metal alloy resistor 20, if a defect is found during the early inspection of the front side of the metal alloy resistor 20, the defective product needs to be promptly removed, and the defective product should not be allowed to go through the entire procedure before being removed, because this will cause redundant inspection of the equipment; therefore, how to pre-inspect the metal alloy resistor 20, detect the defect in time and remove it, is also a technical problem that needs to be solved.

[0045] The metal alloy resistance detection, dust removal and tape braiding device 10 of the present invention is specifically developed based on the above-mentioned technical problems.

[0046] like Figure 4 and Figure 5 As shown, in order to solve the above technical problems, the equipment of the present invention is designed with a pre-inspection mechanism 200 and a full-inspection mechanism 300. The pre-inspection mechanism 200 performs an early pre-inspection on the metal alloy resistor 20 to promptly discover problems and remove defective products in a timely manner. The full-inspection mechanism 300 then performs a post-inspection on the metal alloy resistor 20, thereby realizing the inspection of the front and back sides of the metal alloy resistor 20 without using a "flipping device".

[0047] like Figure 4 and Figure 5 As shown, when the pre-inspection mechanism 200 is used to perform preliminary inspection on the metal alloy resistor 20, since only a simple preliminary inspection of the front appearance and size of the metal alloy resistor 20 is performed, in order to improve the stability of transmission, the auxiliary turntable 210 adopts a supporting structure, and the metal alloy resistor 20 is accommodated in the receiving groove of the auxiliary turntable 210. The metal alloy resistor 20 becomes very stable during the transmission process and is not easy to deviate or fall.

[0048] like Figure 4 and Figure 5 As shown, a full inspection mechanism 300 is used to inspect the bottom appearance and dimensions of the metal alloy resistor 20. At the same time, electrical performance inspection is also required. The main turntable 310 adopts a suspended structure. The metal alloy resistor 20 is placed on the main turntable 310 in a suspended form. The main turntable 310 drives the metal alloy resistor 20 to pass through each inspection device in turn.

[0049] It should be noted that since the metal alloy resistor 20 is placed on the main turntable 310 in a hanging form, when passing through the bottom ion dust removal device 350, the bottom ion dust removal device 350 will perform ion blowing dust removal on the bottom surface of the metal alloy resistor 20 (such as Figure 4 As shown in FIG. 4 , the metal alloy resistor 20 is affected by the airflow and slightly deviates, which affects the subsequent braiding process and makes the metal alloy resistor 20 unable to accurately fall into the braiding groove. For this reason, a corresponding deviation correction device (such as Figure 7 As shown), the offset metal alloy resistor 20 is corrected so that the metal alloy resistor 20 can fall into the braid groove in a correct posture.

[0050] Next, the specific structure of the feeding mechanism 100 is described:

[0051] like Figure 3As shown, the feeding mechanism 100 includes: a vibration plate 110 and a direct vibrator 120. The direct vibrator 120 is connected between the vibration plate 110 and the auxiliary rotating plate 210, and the direct vibrator 120 is used to transport the metal alloy resistor 20 at the discharge port of the vibration plate 110 to the receiving groove 211 of the auxiliary rotating plate 210. Figure 3 As shown, further, the feeding mechanism 100 also includes a feeding bin 130 located above the main vibration disk 110, and the feeding bin 130 is used to replenish the metal alloy resistor 20 in the main vibration disk 110 in time to prevent the main vibration disk 110 from being out of material.

[0052] like Figure 3 As shown, in the present invention, a resistor in place detector 140 is provided at the connection between the straight vibrator 120 and the auxiliary turntable 210. The resistor in place detector 140 is used to detect whether the metal alloy resistor 20 in the receiving groove 211 of the auxiliary turntable 210 is accurately in place. If it is detected that there is no metal alloy resistor 20 in the receiving groove 211, the resistor in place detector 140 sends a material shortage signal to the control center, and the control center issues an alarm.

[0053] Next, the specific structure of the pre-check bad removal device 240 is described:

[0054] like Figure 3 As shown, the pre-inspection defective removal device 240 includes: a pre-inspection defective air blowing pipe 241 and a pre-inspection defective hopper 242. The pre-inspection defective air blowing pipe 241 blows air to blow the defective metal alloy resistor 20 on the auxiliary turntable 210 into the pre-inspection defective hopper 242. In the present invention, the defective products are mainly removed by blowing air. Compared with the traditional method of clamping with mechanical claws, this method can achieve fast and effective removal of defective products.

[0055] Next, the specific structure of the main turntable 310 is described: Figure 5 As shown, the main turntable 310 includes a turntable body 311 and a driving module for driving the turntable body 311 to do lifting and rotational motion. The turntable body 311 is provided with a plurality of negative pressure suction nozzles 312 along its circumference. Driven by the driving module, the turntable body 311 does both lifting and rotational motion, so that the metal alloy resistor 20 on the negative pressure suction nozzle 312 can accurately reach each station.

[0056] Next, the specific structure of the CCD flatness detection device 330 is described:

[0057] like Figure 5As shown, the CCD flatness detection device 330 includes: a flatness detection station 331, a flatness detection CCD 332, and a flatness detection backlight 333. The flatness detection CCD 332 and the flatness detection backlight 333 are respectively located on both sides of the flatness detection station 331. The metal alloy resistor 20 is placed on the flatness detection station 331, and the light of the flatness detection backlight 333 is irradiated on the metal alloy resistor 20, leaving a light shadow on the flatness detection station 331. The flatness detection CCD 332 takes a photo of the light shadow for analysis and detection. If the light shadow is a straight line, the metal alloy resistor 20 is determined to be a qualified product. If the light shadow is a curved arc, the metal alloy resistor 20 is determined to be a defective product.

[0058] Next, the specific structure of the braiding mechanism 400 is described:

[0059] like Figure 1 As shown, the braiding mechanism 400 includes: a braiding transmission device 410, a laser printing device 420, and a plastic sealing device 430. The braiding transmission device 410 is used to drive the braid 30 (such as Figure 7 As shown in the figure, the metal alloy resistor 20 is transmitted in a straight line and passes through a laser printing device 420 and a plastic sealing device 430 in sequence. The laser printing device 420 is used to laser print the metal alloy resistor 20 in the braid 30, and the plastic sealing device 430 is used to encapsulate the metal alloy resistor 20 in the braid 30.

[0060] Furthermore, if Figure 1 As shown, the plastic sealing device 430 includes: an unwinding reel 431, a cover film pressing assembly 432, and a reel 433. The unwinding reel 431 is used to unwind the plastic sealing film, the cover film pressing assembly 432 is used to press the plastic sealing film onto the braid 30 to seal the metal alloy resistor 20, and the reel 433 is used to rewind the braid 30 after plastic sealing. When one reel of braid is wound up, the cutting device 440 located at the tail of the braid transmission device 410 cuts the braid 30.

[0061] As can be seen from the above, since the metal alloy resistor 20 is placed on the main turntable 310 in a hanging form, when passing through the bottom ion dust removal device 350 (such as Figure 4 As shown), the bottom ion dust removal device 350 performs ion blowing dust removal on the bottom surface of the metal alloy resistor 20. The metal alloy resistor 20 is affected by the airflow and will be slightly offset (as shown). Figure 6 This will affect the subsequent braiding process, so that the metal alloy resistor 20 cannot fall into the braiding groove accurately.

[0062] In order to solve this technical problem, the braiding mechanism 400 also includes a feed correction device 450 (such as Figure 7 shown).

[0063] like Figure 8 and Fig. 9 As shown, the feed correction device 450 includes: a correction guide sleeve 451, a telescopic rod 452, and a lifting cylinder 453. The telescopic rod 452 is movably sleeved in the correction guide sleeve 451, and the lifting cylinder 453 drives the telescopic rod 452 to reciprocate in the vertical direction in the correction guide sleeve 451. The opening of the correction guide sleeve 451 forms a guiding inclined surface 454 (such as Fig. 9 shown).

[0064] like Figure 8 and Fig. 9 As shown, the turntable body 311 is also provided with a horizontal cylinder 313 for driving the negative pressure suction nozzle 312 to reciprocate in the horizontal direction.

[0065] like Fig.10 As shown, the negative pressure nozzle 312 includes: a nozzle body 3121, a return spring 3122, and a displacement detector 3123. The nozzle body 3121 is movably arranged on the turntable body 311 through the return spring 3122, and the displacement detector 3123 is fixed on the turntable body 311 and is used to detect the displacement of the nozzle body 3121.

[0066] Next, the working principle of the above-mentioned feeding deviation correction device 450 is described:

[0067] Considering that the deviation of the metal alloy resistor 20 is only a small probability event, if each metal alloy resistor 20 is corrected, it will seriously affect the production efficiency. It can be understood that not every metal alloy resistor 20 needs to be corrected. Therefore, the feeding correction device 450 is set on one side of the braiding transmission device 410 and starts working when necessary;

[0068] The nozzle body 3121 sucks the metal alloy resistor 20 and descends into the slot of the braid 30. At this time, the nozzle body 3121 cannot release the metal alloy resistor 20. When the metal alloy resistor 20 approaches the slot of the braid 30, if the metal alloy resistor 20 does not deviate, the metal alloy resistor 20 will not get stuck with the edge of the slot, the nozzle body 3121 will not shrink, and the displacement detector 3123 will not generate an induction signal. It is determined that the current metal alloy resistor 20 can fall into the slot in a correct posture, and the nozzle body 3121 releases the metal alloy resistor 20 to make it fall into the slot.

[0069] If the metal alloy resistor 20 is offset during the previous processing, the metal alloy resistor 20 will be stuck when approaching the groove of the braid 30, and the nozzle body 3121 will be blocked and shrink. The displacement detector 3123 will generate an induction signal and send it to the control center to start the deviation correction work.

[0070] First, the turntable body 311 rises, and the metal alloy resistor 20 is driven to reset through the suction nozzle body 3121. Then, the horizontal cylinder 313 drives the suction nozzle body 3121 to move above the deviation correction guide sleeve 451. The suction nozzle body 3121 releases the metal alloy resistor 20 and makes it fall into the deviation correction guide sleeve 451. The metal alloy resistor 20 is corrected by the guide inclined surface 454 at the opening.

[0071] It should be emphasized that for some metal alloy resistors 20 with larger deviation angles, it is difficult to correct them in one go through the guiding inclined surface 454. For this purpose, a lifting cylinder 453 and a telescopic rod 452 are specially provided. The lifting cylinder 453 drives the telescopic rod 452 to perform telescopic movement on the correction guide sleeve 451, thereby driving the metal alloy resistor 20 to move back and forth on the guiding inclined surface 454. Through multiple corrections, the correct posture of the metal alloy resistor 20 is adjusted, and then it is sucked up by the suction nozzle body 3121 and transferred back to the top of the slot body of the braid 30. As a result, the metal alloy resistor 20 can fall into the slot body with the correct posture.

[0072] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
