Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, in particular to a full-automatic vacuum packaging sealing detection equipment. Background Art

[0002] At present, in the industrialized production of food, products are often packaged in the form of vacuum packaging. Vacuum packaging is mainly achieved by vacuum packaging machines. However, vacuum packaging machines may also cause improper packaging due to special circumstances such as improper operation and aging of parts, making it impossible to store products under vacuum conditions. For more obvious packaging problems, they can be directly detected manually, but for some less obvious packaging problems, there is currently a lack of efficient detection methods. Chinese patent CN113945342B discloses a packaging airtightness detection system, which requires the packaged product to be placed in a sealed shell, and the gas inside the product is discharged after squeezing the product, and then the airtightness of the product is judged by detecting the change in air pressure inside the shell. Although this method can detect the airtightness, the operation is relatively complicated, and it takes a lot of time to perform the detection operation continuously. When there is less gas inside the product packaging, it is necessary to squeeze the product with greater force to discharge the gas, which can easily damage the food. Secondly, the air pressure change is small after squeezing the gas, resulting in missed detection and false detection, and the accuracy rate is not high enough. Summary of the invention

[0034] 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.

[0035] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a fully automatic vacuum packaging sealing detection device.

[0036] Example 1: Please refer to Figure 1 - Figure 4 A fully automatic vacuum packaging sealing detection device comprises a workbench 1, a box 2 is fixed on the top of the workbench 1, a conveying component 4, a negative pressure generating component 5, a driving component 6, a fixing component 7 and a plurality of detectors 8 are installed on the workbench 1, each detector 8 comprises two detectors 8, and the two detectors 8 in the same group are symmetrically distributed up and down, and the detector 8 comprises a suction cup 81 and a pressure sensor 82;

[0037] The conveying component 4 is used to convey the product to be tested;

[0038] The negative pressure generating component 5 is connected to the suction cup 81, and the negative pressure generating component 5 enables the suction cup 81 to generate negative pressure suction;

[0039] The driving assembly 6 is installed on the chassis 2, and the driving assembly 6 is connected to the two detectors 8, and the driving assembly 6 is used to simultaneously drive the two detectors 8 to move vertically;

[0040] The fixing assembly 7 comprises a flexible pressing plate 71 capable of vertical movement, and the fixing assembly 7 is used to fix the product to be tested;

[0041] When the conveying component 4 is in operation, the product to be inspected is conveyed to the inspection station, the fixing component 7 is in operation, and the product to be inspected is fixed by the flexible pressing plate 71, the negative pressure generating component 5 is in operation, so that the two suction cups 81 on the same group of detectors 8 generate suction, the driving component 6 is in operation, and the two detectors 8 are forced to move toward the product at the same time, and the suction cups 81 adsorb the upper and lower surfaces of the flat area of ​​the product, and the driving component 6 is in operation again, forcing the two detectors 8 to move away from the product, and then the upper and lower surfaces of the product are pulled by the suction cups 81, and the pressure sensor 82 monitors the resistance of the suction cups 81 at this time, so as to detect whether the product is leaking;

[0042] In actual use, the feeding end of the conveying component 4 is connected to the output end of the vacuum packaging machine, thereby realizing continuous feeding of the product. The conveying component 4 is sequentially provided with a detection station and a rejection station, and the flexible pressing plate 71 is arranged just above the detection station, as shown in the attached manual. Figure 2 As shown, the product to be detected in this embodiment is a packaging bag and the product inside the packaging bag. The packaging bag body includes a product area a in the center, a heat-pressing and plastic-sealing area b at the edge of the packaging bag, and a flat area c between the product area a and the heat-pressing and plastic-sealing area b, wherein the flat area c is an effective detection area;

[0043] When in use, the conveying component 4 is started, and the conveying component 4 conveys the products to be inspected to the inspection station one by one. When the products arrive at the inspection station, they are stationary. At this time, the products are located between the two suction cups 81 in the same group. At this time, the fixing component 7 is started. When the fixing component 7 is running, the flexible pressing plate 71 moves down, presses the product after contacting it, and prevents the product from moving freely during the subsequent inspection process. Then, the negative pressure generating component 5 and the driving component 6 are started. When the negative pressure generating component 5 is running, the suction cup 81 generates suction. When the driving component 6 is running, the suction cups 81 on the two detectors 8 in the same group are first driven to move toward the product at the same time, so that the two suction cups 81 contact the upper and lower two at the same position on the flat area c on the product respectively. The two suction cups 81 are fixed to the position at the same time by suction, and then the driving assembly 6 continues to operate, and at the same time drives the suction cups 81 on the two detectors 8 in the same group to reset. At this time, since the two suction cups 81 have been adsorbed on the upper and lower surfaces of the product, the movement of the two suction cups 81 will pull the upper and lower surfaces of the product to move in the upper and lower directions respectively. If there is air leakage in the product, the upper and lower surfaces of the product are easy to separate due to the consistent air pressure inside and outside the product, and the pressure sensor 82 detects that the movement resistance of the suction cup 81 is small. If there is no air leakage in the product, the upper and lower surfaces of the product are difficult to separate due to the low air pressure inside the product, and the pressure sensor 82 detects that the movement resistance of the suction cup 81 is large, and then determines whether the product has an airtightness problem;

[0044] By setting up a conveying component 4, a negative pressure generating component 5, a driving component 6, a fixing component 7, a suction cup 81 and a pressure sensor 82 which are symmetrically arranged up and down, when the product is conveyed to the inspection station, the fixing component 7 first stabilizes the product, and then the negative pressure generating component 5 and the driving component 6 are operated, so that the two groups of suction cups 81 are respectively adsorbed on the upper and lower surfaces of the flat area on the product, and then the two groups of suction cups 81 are driven to pull the upper and lower surfaces of the area, and finally the resistance exerted on the suction cups 81 is used to judge the pressure difference between the inside and outside of the product, and then to judge whether the product has leakage. This method can detect continuously, has a high degree of automation, a short detection time, a high detection efficiency, and will not damage the product. There is an obvious difference between leaking products and non-leaking products, and the detection accuracy is high, which is more practical.

[0045] Example 2: See Figure 1 - Figure 5 , which is different from the above embodiment, the conveying assembly 4 includes a conveyor 41 and a support plate 42 located above the workbench 1, the edge of the conveyor 41 is fixed with a support leg, the bottom end of the support leg is fixed to the surface of the workbench 1, and the support plate 42 is provided with two, the two support plates 42 are symmetrically distributed on both sides of the conveyor 41, the bottom of the two support plates 42 are fixedly connected with a bracket, the bottom end of the bracket is fixed to the work surface, the surfaces of the two support plates 42 are opened with a through hole 43, and the suction cup 81 corresponds to the position of the through hole 43;

[0046] The conveyor 41 is configured as a belt type and is controlled by a servo motor. The width of the conveyor 41 is the same as or smaller than the width of the product area a. The surface of the conveyor 41 and the surface of the support plate 42 are both horizontal planes. The heights of the surfaces of the two support plates 42 are lower than the height of the surface of the conveyor 41. The height difference is set between 1 and 10 mm. The through hole 43 is configured as a strip shape, and the width of the through hole 43 is greater than the diameter of the suction cup 81.

[0047] When in use, the product to be inspected is placed on the conveyor 41, and the conveyor 41 is started to drive the product to be inspected to move. When the product to be inspected moves to the inspection station, the conveyor 41 stops running. At this time, the hot pressing and plastic sealing area b and the flattening area c on the product to be inspected are both located on the surface of the support plate 42 on both sides. When the inspection work is completed, the conveyor 41 continues to operate to move the product to the rejection station, and at the same time, the product to be inspected is moved to the inspection station;

[0048] By providing the driving component 6, it is beneficial to realize continuous automatic driving of the product to be inspected, without manual operation, thereby improving the inspection efficiency.

[0049] Example 3, see Figure 1 and Figure 4 , which is different from the above embodiment, the fixing assembly 7 further includes a mounting plate 72, one end of which is fixed to the top of the chassis 2, and the other end of which extends above the conveyor 41. A vertical cylinder 73 is fixed to one end of the mounting plate 72 located above the conveyor 41, and the output end of the vertical cylinder 73 is arranged downward, and the flexible pressing plate 71 is fixedly connected to the output end of the vertical cylinder 73;

[0050] The flexible pressing plate 71 includes a horizontal plate and a latex layer fixed at the bottom of the horizontal plate. When in use, the vertical cylinder 73 extends after operation, pushing the flexible pressing plate 71 downward to contact the product, thereby fixing the product.

[0051] By setting the fixing component 7, it is helpful to fix the product through the flexible pressing plate 71 to avoid random movement during the product inspection process. At the same time, the softness of the flexible pressing plate 71 effectively prevents damage to the product.

[0052] Example 4, see Figure 4 - Figure 8, which is different from the above-mentioned embodiment, a guide hole 21 is provided on one side of the chassis 2 close to the conveying assembly 4, and the driving assembly 6 includes a vertical guide rail 61 fixed inside the chassis 2, a driving motor 62 is fixed to the top of the vertical guide rail 61, and a bidirectional screw 63 is fixed to the output shaft of the driving motor 62, and the bidirectional screw 63 extends into the interior of the vertical guide rail 61 and is rotatably connected to both ends of the vertical guide rail 61, and two sliders 64 are slidably connected in the vertical guide rail 61, and the two sliders 64 are both sleeved on the bidirectional screw 63 and threadedly connected to the bidirectional screw 63, and the two sliders 64 are fixedly connected to a crossbeam 65, and a through hole is provided on the surface of the crossbeam 65 Slot 66, one end of the two crossbeams 65 passes through the guide hole 21 and extends to the outside of the chassis 2, the two crossbeams 65 are located outside the chassis 2 and extend to the top and bottom of the support plate 42 respectively, the two detectors 8 in the same group are respectively mounted on the two crossbeams 65, the two detectors 8 in the same group are matched with the position of the through hole 43, the negative pressure generating assembly 5 includes an air pump 51 fixed inside the chassis 2, the air pump 51 is fixedly connected to an air pipe 52, the air pipe 52 is fixedly connected to a plurality of branch pipes 53, the plurality of branch pipes 53 extend to the outside of the chassis 2 through the guide hole 21, and the plurality of branch pipes 53 are respectively connected to the suction cups 81 on the plurality of detectors 8;

[0053] The driving assembly 6 and the guide hole 21 are preferably arranged in two groups, and two groups of detectors 8 are arranged on each group of driving assembly 6, and a total of four groups of detectors 8 are arranged for detection, which has a higher fault tolerance rate. The guide hole 21 is arranged in a vertical bar shape, and the surface of the bidirectional screw 63 is provided with two groups of threads symmetrically distributed and in opposite directions, and the two sliders 64 are matched with the two groups of threads on the bidirectional screw 63 respectively;

[0054] When in use, start the air pump 51. After the air pump 51 is running, suction is generated, so that the airflow enters the air pump 51 from the suction cup 81, the branch pipe 53 and the air pipe 52 in turn, thereby generating suction on the suction cup 81, driving the motor 62. The driving motor 62 drives the bidirectional screw 63 to rotate, driving the two sliders 64 to slide toward the middle of the bidirectional screw 63 at the same time, thereby driving the two cross beams 65 to approach the support plate 42, thereby driving the detectors 8 symmetrically installed on the two cross beams 65 to move toward the support plate 42, and finally the suction cup 81 on the detector 8 above the support plate 42 contacts the top surface of the product, and the suction cup 81 on the detector 8 below the support plate 42 passes through the through hole 43 and contacts the bottom surface of the product. When the suction cup 81 fits the product, it is tightly adsorbed on the surface of the product. After the suction cup 81 adsorbs the product, the driving motor 62 drives the bidirectional screw 63 to rotate in the opposite direction. Similarly, the suction cups 81 that have been adsorbed on the upper and lower sides of the product are driven to reset, and detection is achieved by pulling the upper and lower sides of the product.

[0055] By setting up the driving component 6 and using the driving motor 62 to control the two symmetrical detectors 8 to move toward the product and reset at the same time, it is beneficial to drive the suction cup 81 to first absorb the upper and lower sides of the product and then pull the upper and lower sides of the product, thereby facilitating the automatic detection work.

[0056] Example 5, see Figure 6 and Figure 7 , different from the above embodiment, the detector 8 also includes a movable seat 83 installed inside the through groove 66, and a vertical tube 84 is movably inserted on the movable seat 83. The end of the vertical tube 84 close to the through hole 43 is fixedly connected to the suction cup 81, and the end of the vertical tube 84 away from the through hole 43 is fixedly connected to the branch pipe 53. The end of the vertical tube 84 connected to the branch pipe 53 is fixedly sleeved with a limiting ring 85, the pressure sensor 82 is sleeved on the outside of the vertical tube 84 and fixedly connected to the limiting ring 85, and a spring 86 is fixedly connected between the pressure sensor 82 and the movable seat 83, and the spring 86 is sleeved on the outside of the vertical tube 84.

[0057] Among them, the spring 86 is connected to the pressure-bearing surface of the pressure sensor 82. When in use, when the crossbeam 65 moves toward the product, it drives the movable seat 83 to move, and then drives the spring 86, the pressure sensor 82, the limit ring 85, the vertical pipe 84 and the suction cup 81 on the movable seat 83 to move. When the suction cup 81 contacts the surface of the product, it stops moving. The crossbeam 65 that continues to move only drives the movable seat 83 to move, so that the spring 86 is stretched. The elastic force of the deformed spring 86 makes the suction cup 81 contact the surface of the product more closely, ensuring that the suction cup 81 is tightly adsorbed to the surface of the product. When the crossbeam 65 is away from the product, it first The spring 86 is restored to its original length. After that, if the product is not leaking, the air pressure inside it is low, and the suction cups 81 adsorbed on both sides of the product are difficult to separate from the product, resulting in the suction cups 81, the vertical tube 84, the limit ring 85 and the pressure sensor 82 being stationary. The crossbeam 65 continues to move away from the product and squeezes the spring 86. The elastic force of the spring 86 acts on the pressure sensor 82. The pressure sensor 82 detects an increase in the pressure value. If the product is leaking, the air pressure inside and outside the product is consistent. When the two suction cups 81 move, it is easy to pull the two sides of the product. The spring 86 will not be compressed, and the value monitored by the pressure sensor 82 is low.

[0058] By setting up the detector 8 and utilizing the pressure of the spring 86 on the pressure sensor 82, it is possible to effectively feedback the resistance of the suction cup 81 when adsorbing the product, thereby determining the air tightness more accurately and efficiently.

[0059] Example 6, see Figure 6 , Figure 7 , Fig. 9 and Fig.10, which is different from the above-mentioned embodiment, the bottom of the mounting plate 72 is rotatably connected to a vertical shaft 9, the bottom end of the vertical shaft 9 is fixedly connected to a support rod 10, one end of the support rod 10 extends to the bottom of the flexible pressing plate 71 and is fixed with an industrial camera 11, the end of the crossbeam 65 is fixedly connected to an adjusting motor 12, the output shaft of the adjusting motor 12 is fixedly connected to an adjusting screw 13, the adjusting screw 13 extends to the inside of the through slot 66 and is rotatably connected to the inner wall of the through slot 66, the adjusting screw 13 passes through the movable seat 83 and is threadedly connected to the movable seat 83, and the movable seat 83 is slidably connected to the inner wall of the through slot 66 , a driven bevel gear 14 is fixedly connected to the vertical shaft 9, a horizontal shaft 15 is also provided at the bottom of the mounting plate 72, the horizontal shaft 15 is mounted at the bottom of the mounting plate 72 through a bearing seat 16, one end of the horizontal shaft 15 is fixedly connected to a driving bevel gear 17, the driving bevel gear 17 is meshed with the driven bevel gear 14, a driving gear 18 is also fixedly connected to the middle of the horizontal shaft 15, an incomplete rack 19 is fixedly connected to the edge of the flexible pressing plate 71, the incomplete rack 19 is meshed with the driving gear 18, and the top end of the incomplete rack 19 passes through the mounting plate 72 and is vertically slidably connected to the mounting plate 72;

[0060] In the initial state, the industrial camera 11 is located directly above the inspection station. When the product moves to the inspection station, the industrial camera 11 collects the position of the product to determine the position of the effective inspection area on the product.

[0061] When in use, after the industrial camera 11 captures the position of the effective detection area on the product, the adjustment motor 12 is started. After the adjustment motor 12 is running, it drives the adjustment screw 13 to rotate. The adjustment screw 13 drives the movable seat 83 to slide along the inside of the through groove 66. When the movable seat 83 moves, it drives the suction cup 81 to move, and then adjusts to a reasonable detection point. When the fixing component 7 is running, the flexible pressure plate 71 moves downward and drives the incomplete rack 19 to move downward. The incomplete rack 19 drives the driving gear 18 to rotate. When the driving gear 18 rotates, it drives the horizontal shaft 15 and the active bevel gear 17 to rotate. When the active bevel gear 17 rotates, it drives the driven bevel gear 14 to rotate. When 14 rotates, it drives the vertical axis 9 to rotate, and then drives the support rod 10 and the industrial camera 11 to swing around the vertical axis 9, so that the industrial camera 11 is pre-detached from the bottom of the flexible pressure plate 71, which does not affect the operation of the flexible pressure plate 71. Then the flexible pressure plate 71 continues to move downward, and at this time the incomplete rack 19 is detached from the drive gear 18, so that the drive gear 18 is stationary, the horizontal axis 15, the vertical axis 9, the support rod 10 and the industrial camera 11 are stationary. When the flexible pressure plate 71 moves up and resets, the incomplete rack 19 meshes with the drive gear 18 again and drives the drive gear 18 to rotate. When the flexible pressure plate 71 is reset, the industrial camera 11 also moves back to the bottom of the flexible pressure plate 71;

[0062] By setting up the industrial camera 11, it is beneficial to collect the position of the effective detection area on the product in real time. When the position of the effective detection area does not match the position of the suction cup 81, the detector 8 is driven to move by adjusting the motor 12, and then the position of the suction cup 81 is adjusted, thereby improving the applicability. By setting an incomplete rack 19 on the edge of the flexible pressure plate 71, the industrial camera 11 can be driven to move first when the flexible pressure plate 71 is working, so as to avoid the industrial camera 11 interfering with the operation of the flexible pressure plate 71.

[0064] The guide rod 33 is consistent with the output direction of the transverse cylinder 31, and the push plate 32 corresponds to the position of the rejection station. When in use, when the product is detected to be leaking, the leaking product is transported to the rejection station by the conveying component 4, and the transverse cylinder 31 operates and extends, driving the push plate 32 to move, and the push plate 32 just pushes the product onto the unloading ramp 34, so that the product slides off the unloading ramp 34;
