Vacuum leak detection: the plastic soft bag is placed in the detection chamber, and the change in pressure in the detection chamber is measured to determine whether it is leaking; 3. Crystallization leak detection: using the principle that some liquid medicine contacts the atmosphere and undergoes recombination crystallization, through certain physical conditions, observe whether there is crystallization on the outer surface of the plastic soft bag, so as to determine whether the liquid medicine is leaking; the above are traditional soft bag leak detection methods, all of which have limitations to varying degrees and low efficiency; and in the current detection process, a flat mesh belt is used to transmit the soft bag, and a single detection device is set on the mesh belt to detect the head and body of the soft bag at the same time. Due to the different structures and wall thicknesses of the soft bag body and the head, a single detection device cannot accurately detect the defects of the head and the bag body, and because the liquid in the bag body cannot ensure that all positions of the bag body are filled when the soft bag is placed flat, the high-pressure detection result of the soft bag is inaccurate and the stability is poor.

[0049] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0050] like Figure 1-Figure 22 As shown, the specific structure of the present invention is:

[0051] A double-chamber soft bag high-pressure detection device, comprising a frame 13, on which a detection channel device 14 is arranged; a feeding mesh belt 11 is arranged at the feeding end of the detection channel device 14, and an output mesh belt 15 is arranged at the output end; a waste rejection device 16 is arranged above the output mesh belt 15; the detection channel device 14 comprises a wavy soft bag conveyor belt 71 composed of a plurality of parallel power rollers 711 connected to each other by a connecting belt 713; at least one group of bag head detection devices 5 and a plurality of bag body detection devices are arranged on the detection station of the soft bag conveyor belt 71; the bag head detection device 5 and the bag body detection device A probe is provided on the end of the detection device that contacts the double-chamber double-chamber soft bag 10; the bag body detection device includes a bag body front detection device 4 located above the soft bag conveyor belt 71 and a bag body back detection device 8 below; the bag body detection device is arranged at an inclined surface position on the soft bag conveyor belt 71, and the inclined surface is composed of at least two powered rollers 711 connected to each other by a connecting belt 713; a bag tail clamping device 17 is provided above the soft bag conveyor belt 71; the bag tail clamping device 17 includes a clamping conveyor belt 78 located above the soft bag conveyor belt 71 and used to press the tail end of the double-chamber double-chamber soft bag 10.

[0052] The track conveying surface of the soft bag conveyor belt 71 adopts a conveying surface with an undulating wave-shaped structure for conveying. The inclined surface on the conveying surface can ensure that the liquid fills the detection area on one side of the bag body, and the detection station can better capture the leakage point; the detection devices are arranged above and below the bag body to simultaneously detect the front and back sides of the bag body to ensure detection stability and accuracy; the electrodes are cross-arranged at each detection station to achieve dead-angle detection of the bag body, allowing the probe to approach each leakage point, ensuring detection sensitivity, reducing false detections, and eliminating missed detections.

[0053] The tail ends of the power rollers 711 are connected to each other through a driving belt 712 and then driven to rotate by a driving motor 714 .

[0054] Further improvements based on the above technical solutions:

[0055] like Figure 7-9 As shown in Figure 11, a long strip of negative pressure chamber component 76 is arranged between the upper and lower surfaces of the clamping conveyor belt 78; the bottom surface of the negative pressure chamber component 76 is provided with strip suction slits 761 distributed along the conveying direction; suction holes 781 matching the suction slits 761 are distributed on the belt surface of the clamping conveyor belt 78; the negative pressure chamber component 76 is connected to a negative pressure source through a pipeline.

[0056] Rollers 782 are evenly arranged on both sides of the clamping conveyor belt 78; the rollers 782 are arranged in corresponding guide grooves 783 on both sides; the bottom surface of the negative pressure chamber component 76 and the guide groove 783 are both wavy shapes that match the soft bag conveyor belt 71; the guide groove 783 is arranged on the frame 13 or the negative pressure chamber component 76.

[0057] After the double-chamber double-chamber soft bag 10 enters the detection channel, its tail immediately enters the clamping mechanism, and the double-chamber soft bag is clamped by the clamping conveyor belt 78 and the soft bag conveyor belt 71. During the conveying process of the bag body on the power roller of the soft bag conveyor belt 71, it is immediately sucked by the clamping conveyor belt 78 to ensure the stability of the conveying without causing damage to the soft bag chamber. The overall synchronous and orderly conveying of the bag body is ensured; the problem of the double-chamber soft bag slipping during the conveying process causing the disorder of the workstation is solved, and the hidden danger of the bag body being instantly detained and causing the bag to overlap is solved; the problem of unstable high-voltage detection caused by the skewness of the bag body is solved. Essentially, the problem of frequent alarms during the detection process caused by the skewness and slippage of the bag body is solved, the operating efficiency of the detection equipment is improved, and the false detection rate is reduced.

[0058] like Figure 19-21 As shown, the bag head detection device 5 includes a cross bar 502 arranged above the soft bag conveyor belt 71; a return frame 503 and an upper discharge frame 505 are arranged on the cross bar 502; a lower discharge frame 508 located directly below the upper discharge frame 505 is arranged below the soft bag conveyor belt 71; a discharge needle 510 for contacting the soft bag head is arranged at the lower end of the upper discharge frame 505 and the upper end of the lower discharge frame 508; a negative electrode sheet 511 for contacting the soft bag body is arranged at the lower end of the return frame 503; a negative electrode interface 2 504 is arranged on the return frame 503; an upper positive electrode interface 506 is arranged on the upper discharge frame 505; and a lower positive electrode interface 509 is arranged on the lower discharge frame 508.

[0059] The bag head detection device is fixed on the wall panel 79 through a vertical plate, and a vertical waist-shaped hole is set on the vertical plate, and the cross bar 502 is installed in the waist-shaped hole by bolts; the cross bar 502 can be rotated and raised and lowered on the vertical plate 501; the rear ends of the loop frame 503 and the upper discharge frame 505 are provided with clamp-shaped mounting holes, which are sleeved on the cross bar 502 and fixed by bolts. Therefore, the movement position and rotation angle of the loop frame 503 and the upper discharge frame 505 can be adjusted by loosening the bolts to adjust the detection range. The bottom detection electrode is fixed by the lower discharge frame 508, and the lower discharge frame 508 is installed on the insulating bracket 507, and the position can be fine-tuned; the bag body passes through the detection channel, and the discharge needles at the upper and lower positions flexibly change along the outer extension trajectory of the soft bag head contour, and the negative electrode sheet 511 is attached to the bag body. When the soft bag leaves the detection channel, the discharge needle 510 and the negative electrode sheet 511 automatically return to their original state to prepare for the next detection.

[0060] The positive electrode needles of the bag head detection device are arranged crosswise up and down to fully cover the area around the head, thereby increasing the probability and sensitivity of capturing leakage points. The flexible adjustment of the positive and negative electrode spacing can greatly increase the detection high voltage, and the stable circuit ensures the detection sensitivity, reduces the false detection rate, and solves the problem of missed detection.

[0061] like Figure 12-15 As shown, the bag body front detection device 4 includes a probe rack 403 arranged above the soft bag conveyor belt 71; a short installation shaft 405 and a long installation shaft 406 that are independently separated from each other are arranged at the same horizontal axis position in the probe rack 403; a rotatable probe seat 412 is evenly arranged on the short installation shaft 405 and the long installation shaft 406 through bearings; a detection needle 404 is arranged on the probe seat 412; one end of the short installation shaft 405 is connected to the negative electrode interface 408; one end of the long installation shaft 406 is connected to the positive electrode interface 409.

[0062] 408 is the negative line interface, 409 is the positive line connection port, the detection needle 404 is supported and separated by the probe frame 403, a plate-like negative electrode sheet is installed on the left side, and a needle-like positive electrode rod is installed on the right side. The same-polarity probes are separated by a spacer sleeve 407, and the two ends of the installation axis are fixed with limit sleeves to limit the axial displacement of the probe; when the double-chamber soft bag 10 moves over, the probe rotates and swings along the outer extension trajectory of the bag body contour without interfering with each other, and the probe follows the random shape characteristics of the bag body surface, flexibly and automatically adjusts up and down, so that the probe trajectory covers the surface of the soft bag to capture the leakage point; the device uses the radiating pole and the receiving pole on the same side to shorten the detection loop distance, and at the same time can achieve an increase in the detection voltage and improve the detection sensitivity; the probes are arranged on the same side, which can greatly increase the detection high voltage and improve the sensitivity of capturing the leakage point. The reset spring sheet is used to realize the automatic reset of the probe, which is not affected by gravity, improves the reset speed, reduces the false detection rate, and solves the problem of missed detection.

[0063] like Fig.14 As shown, a counterweight block 415 is installed on the detection needle 404, and an insulating limit plate 416 is provided at the bottom of the probe seat 412. When the probe is separated from the outer extension of the bag, the detection needle 404 automatically returns to the position of the insulating limit plate 416 under the gravity of the counterweight block 415 to prepare for the next detection.

[0064] like Fig.15 As shown, the probe frame 403 is vertically provided with a reset spring piece 411 that matches each probe seat 412; the upper end of the reset spring piece 411 is fixed in the probe frame 403; the side of the probe seat 412 facing the reset spring piece 411 is an arc surface, and a plane that fits the reset spring piece 411 is provided on the arc surface.

[0065] When the soft bag passes through the probe, the probe seat 412 rotates accordingly, the plane at the front end of the probe seat 412 loses coordination with the reset spring sheet 411, and the arc outer wall of the probe seat 412 squeezes the reset spring sheet 411, causing it to deform. When the detection needle 404 breaks away from the outer extension of the bag body, the detection needle 404 loses the squeezing of the double-chamber soft bag 10, and the reset spring sheet 411 exerts reverse squeezing on the probe seat 412, causing the probe seat 412 to form a reset rotation, thereby driving the detection needle 404 to return to its original position. When the outer wall plane of the probe seat 412 fits with the reset spring sheet 411, the probe position is limited, preparing for the next detection.

[0066] like Figure 16-18 As shown, the bag back side detection device 8 includes an electrode mounting plate 801 arranged below the soft bag conveyor belt 71, and a short mounting shaft 802 and a long mounting shaft 806 that are independently separated from each other at the same horizontal axis position above the electrode mounting plate 801; a rotatable probe seat 808 is evenly installed on the short mounting shaft 802 and the long mounting shaft 806 through bearings; the short mounting shaft 802 is connected to the negative terminal; the long mounting shaft 806 is connected to the positive terminal; an L-shaped probe rod 803 is installed on the probe seat 808; a counterweight block 811 is provided at the tail of the horizontal section at the lower end of the probe rod 803, and a needle is provided at the end of the vertical section at the upper end; the front end of the needle is bent at 90°.

[0067] When the soft bag is conveyed by the soft bag conveyor belt, the bottom surface of the soft bag slides over the front end of the probe, and the probe is pressed against the bottom surface of the soft bag, so that the probe rotates and swings under pressure, and the front end is pressed down for detection; when the probe is separated from the extension of the soft bag, the probe automatically returns to the initial position under the gravity of the counterweight block 811, preparing for the next detection.

[0068] like Figure 5-6 As shown, the reject device 16 includes a reject conveyor belt 161 disposed transversely above the output mesh belt 15; a protruding reject plate 162 is disposed on the reject conveyor belt 161. When unqualified double-chamber soft bags 10 are conveyed out through the output mesh belt 15, the reject motor 163 is started to drive the reject conveyor belt 161 to rotate, and the reject plate 162 on the reject conveyor belt 161 pushes the unqualified double-chamber soft bags 10 away from the output mesh belt 15.

[0069] An accelerating mesh belt 12 is arranged between the feeding mesh belt 11 and the detection channel device 14. The feeding mesh belt 11 slowly conveys

[0070] like Fig. 22 As shown, the bag body detection device is provided with four groups. The oblique line covered part in the figure is the positive electrode probe detection part, and the grid covered part is the negative electrode probe detection part. Fig. 22It is a schematic diagram of the inspection surface of the corresponding front inspection station one 41, front inspection station two 42, front inspection station three 43, front inspection station four 44, back inspection station one 81, back inspection station two 82, back inspection station three 83, and back inspection station four 84.

[0071] Four sets of bag body inspection devices cross-cover all inspection areas of the soft bag, perform repeated inspections, and improve the comprehensiveness and accuracy of inspections.

[0073] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
