Description

Technical Field

[0001] The present application relates to the field of detection equipment, and in particular to a leak detection device for ointment packaging tubes. Background Art

[0002] Currently, the production and processing of paste products (such as toothpaste, ointments, and sauces) primarily involves filling and sealing equipment to fill the paste into the corresponding ointment packaging tube, heat-sealing the tube end, and finally discharging the filled tube through the discharge end of the filling and sealing equipment. Existing filling and sealing equipment can output multiple tubes at a time, which are then distributed to conveying equipment at different output ends.

[0003] To ensure overall product quality, hoses exiting the filling and sealing equipment must be inspected to promptly screen out leaking, substandard products. Currently, hose inspection primarily involves manually pressing the hose to observe for paste leaks at the mold and seal points. Alternatively, specialized extrusion equipment can be used to squeeze several hoses at once, followed by visual inspection for leaks.

[0004] Regarding the above-mentioned related technologies, leak detection of hoses generally requires direct or indirect manual intervention to complete. On the one hand, the overall leak detection efficiency is low, which is difficult to meet the needs of high-output production lines. On the other hand, manual leak detection depends on the operator's experience and technical level, and is prone to missed detection due to factors such as fatigue. Therefore, there is room for improvement. Summary of the Invention

[0005] In order to improve the leak detection efficiency of the hose, the present application provides an ointment packaging hose leak detection device.

[0006] The present application provides a leak detection device for ointment packaging tubes, which adopts the following technical solution:

[0007] An ointment packaging tube leak detection device includes a conveying line, a feeding mechanism, a squeezing mechanism, a visual mechanism, a rejection mechanism, and a qualified product conveying mechanism;

[0008] The conveying line is used to convey the hose;

[0009] The feeding mechanism is connected to the discharge end of the filling and sealing equipment, and is used to receive the hose output by the filling and sealing equipment and transmit it to the conveying line;

[0010] The extrusion mechanism is located downstream of the feeding mechanism, and the extrusion mechanism is used to extrude the hose;

[0011] The visual mechanism is located downstream of the extrusion mechanism, and is used to obtain an image of the extruded hose and determine whether the hose is leaking;

[0012] The rejection mechanism is located downstream of the visual mechanism, and is used to reject the leaking hose from the conveyor line according to the judgment result of the visual mechanism;

[0013] The qualified product conveying mechanism is located downstream of the rejecting mechanism, and is used to receive qualified hoses transmitted from the conveying line.

[0014] By adopting the above technical solution, after the hose is discharged from the filling and sealing equipment, it is first transferred to the conveyor line by the loading mechanism. When the conveyor line delivers the hose to the extrusion mechanism, the extrusion mechanism squeezes the hose on the conveyor line to expose potential leaks. Next, the visual mechanism captures an image of the extruded hose and analyzes the image to determine whether the hose is leaking. Leaking hoses are removed from the conveyor line by the rejection mechanism. Qualified hoses are transferred from the conveyor line to the qualified product conveying mechanism, where they are further transported to the next processing step. This achieves automatic inspection and rejection of discharged hoses, reducing labor intensity and false detection rates compared to traditional manual inspection methods, while also reducing manual intervention and effectively improving the efficiency of hose leak detection.

[0015] Preferably, the conveyor line includes a loading conveyor belt, the loading conveyor belt is evenly distributed with a plurality of loading parts, the loading parts include a plurality of station slots for placing hoses, and the station slots are connected to the conveying surface corresponding to the loading conveyor belt.

[0016] By adopting the above technical solution and setting the workstation slots, the orderly arrangement and limiting of the hoses during the transportation process are achieved, which is beneficial to limiting the displacement or flipping of the hoses during the transportation process, and facilitates the subsequent extrusion mechanism and the rejection mechanism to better extrude and reject the hoses on the conveyor line respectively, thereby improving the accuracy and reliability of subsequent extrusion detection.

[0017] Preferably, the feeding mechanism includes several first feeding conveyor belts, and the input ends of the several first feeding conveyor belts are connected one by one with the output ends of the filling and sealing equipment. The output ends of the first feeding conveyor belts are all arranged close to the loading conveyor belt, and the first feeding conveyor belt is used to transport the hose to the work station slot.

[0018] By adopting the above technical solution, multiple first loading and feeding parts are used to connect to several discharge ends of the filling and sealing equipment, which is conducive to quickly transferring the hoses from different output ends of the filling and sealing equipment to the workstation slots on the loading conveyor belt, realizing multi-channel synchronous feeding, which is conducive to improving the feeding efficiency of the hose.

[0019] Preferably, the feeding mechanism also includes several second feeding conveyor belts, several of the first feeding conveyor belts correspond one-to-one to several of the second feeding conveyor belts, several of the second feeding conveyor belt input ends are connected one-to-one with several conveying ends of the filling and sealing equipment, and the output ends of the second feeding conveyor belts are connected with the corresponding input ends of the first feeding conveyor belts, and the second feeding conveyor belts are used to convey the hoses to the corresponding first feeding conveyor belts.

[0020] By adopting the above technical solution, the output speed of hoses at different discharge ends of the filling and sealing equipment is prone to inconsistency. By setting up a second feeding conveyor belt, the second feeding conveyor belt can be used as a buffer zone. After the discharge end of the filling and sealing equipment transfers the hoses to the second feeding conveyor belt, the second feeding conveyor belt is paused to temporarily store the hoses from each discharge end. After the hoses at the discharge end of the filling and sealing machine have reached the corresponding second feeding conveyor belt, the second conveyor belt will uniformly transfer the hoses to the corresponding first feeding conveyor belt. This helps ensure that each station slot of the loading section moved to the feeding mechanism can accurately receive the hoses, avoiding the phenomenon of empty station slots due to delayed delivery of hoses from individual discharge ends.

[0021] Preferably, the extrusion mechanism includes an extrusion bracket, on which several extrusion parts are vertically installed corresponding to the several work station slots of the loading part, and the extrusion parts are located above the conveying path of the work station slots; the extrusion bracket is also provided with a lifting drive member for driving the extrusion parts to rise and fall vertically.

[0022] By adopting the above technical solution, after the conveyor line transports several workstation slots on the loading part to the bottom of several extrusion parts of the extrusion mechanism, the lifting drive member drives the corresponding extrusion part to descend vertically and apply uniform pressure to the hose, thereby realizing batch extrusion of the hose. Compared with the manual extrusion method of the hose, it is beneficial to reduce errors caused by human factors and improve the overall extrusion efficiency of the hose. At the same time, it is beneficial to uniform force on the hose, so that the paste in the leaking hose is better squeezed out.

[0023] Preferably, the rejection mechanism includes a pushing part and a collection box, the pushing part and the collection box are respectively located on opposite sides of the conveyor line, and the pushing part and the collection box are arranged opposite to each other, the pushing part includes a pushing bracket, the pushing bracket is provided with a pushing block corresponding to the work station slot, the pushing bracket is provided with a pushing driving member corresponding to the pushing block, and the pushing driving member is used to drive the corresponding pushing block to move toward or away from the conveyor line.

[0024] By adopting the above technical solution, when the loading conveyor belt transports the work station slot loaded with the leaking hose to the position opposite to the pushing block, the sliding drive component drives the corresponding pushing block to slide into the work station slot, so as to push the leaking hose in the work station slot into the collection box, thereby realizing automatic removal of the leaking hose and effectively improving the removal efficiency of unqualified hoses.

[0025] Preferably, a guide cover is provided at the end of the conveyor line, the bottom end of the guide cover is located at the bottom of the conveyor line, and when the work station slot is located in the guide cover, the notch at the top of the work station slot is located close to the inner periphery of the guide cover;

[0026] The qualified product conveying mechanism is located below the conveying line; the qualified product conveying mechanism includes a receiving conveyor belt; the receiving conveyor belt is located below the bottom end port of the air deflector; the receiving conveyor belt is used to receive and transport the qualified hoses that fall out of the work station slot.

[0027] By adopting the above technical solution, the guide cover is used in conjunction with the loading conveyor belt to limit the situation where the hose falls out of the work station slot during the movement of the work station slot at the end of the loading conveyor belt, which is conducive to the qualified hose in the work station slot being transported to the bottom of the loading conveyor belt. When the work station slot containing the qualified hose moves out of the bottom end port of the guide slot, the qualified hose inside the work station slot automatically falls onto the receiving conveyor belt, realizing the automatic discharge and transfer of the qualified hose.

[0028] Preferably, the receiving conveyor belts are provided in plurality, and the plurality of receiving conveyor belts are arranged in parallel along the conveying direction of the conveying line;

[0029] The qualified product conveying mechanism further includes a merging conveyor belt and a blocking member; the conveying surface of the merging conveyor belt is supported by two guide plates, and the distance between the two guide plates gradually decreases from the input end of the merging conveyor belt toward the output end of the merging conveyor belt; the output ends of the plurality of receiving conveyor belts are connected to the input end of the merging conveyor belt;

[0030] The blocking member is blocked above the receiving conveyor belt close to the air guide cover, and the blocking member is arranged to slide horizontally;

[0031] After the receiving conveyor belt away from the deflector receives the qualified hose dropped from the corresponding workstation slot and conveys it to the merging conveyor belt, the blocking piece is slid to open the receiving conveyor belt close to the deflector.

[0032] By adopting the above technical solution, multiple receiving conveyor belts can simultaneously receive qualified hoses from different workstation slots and transport them to the merging conveyor belt, which will then cooperate to transport them to the next process, effectively improving the transfer and transportation efficiency of qualified hoses. Through the setting of the blocking parts, the hoses in adjacent workstation slots can be made to fall into the corresponding receiving conveyor belts front and back, which is conducive to reducing the situation where the hoses in adjacent workstation slots fall into the corresponding receiving conveyor belts at the same time, causing subsequent hoses to be blocked or confused during the transportation process of the merging conveyor belt, and is conducive to the orderly entry of the hoses into the merging conveyor belt.

[0033] Preferably, it further comprises a cleaning mechanism, the cleaning mechanism being located downstream of the qualified product conveying mechanism; and the cleaning mechanism being located below the conveying line; the cleaning mechanism being used to clean the station slot loaded with the leaking hose according to the judgment result of the visual mechanism;

[0034] The cleaning mechanism includes a cleaning box, in which a plurality of cleaning parts are provided corresponding to the plurality of station slots of the loading part. The cleaning parts include vertically supported cleaning pipes connected to a water source and an air source.

[0035] By adopting the above technical solution, after the hose is squeezed by the squeezing mechanism, the paste in the leaked hose is likely to leak out and remain in the loading station slot, causing interference with the inspection of the next batch of hoses. With the installation of the cleaning mechanism, when the several station slots of the loading section are moved above the corresponding cleaning pipes, the corresponding cleaning pipes will spray water and blow air to dry the station slots contaminated by the paste to remove the residual paste in the station slots, ensuring that the station slots are clean for the next use.

[0036] Preferably, the loading conveyor belts are provided with two groups, and the two groups of the loading conveyor belts are arranged in parallel; the number of the loading parts on the loading conveyor belts is three;

[0037] When one of the loading parts of a group of the loading conveyor belts is located at the loading mechanism, the other two loading parts of the group of the loading conveyor belts are respectively located at the rejection mechanism and the qualified product conveying mechanism; at the same time, two of the loading parts of another group of the loading conveyor belts are respectively located at the extrusion mechanism and the cleaning mechanism.

[0038] By adopting the above technical solution and utilizing the two loading conveyor belts to cooperate with each other, it is beneficial to adapt to the operating characteristics of different processes, so that processes that require intermittent and rapid movement of the loading part, such as the feeding mechanism, the rejection mechanism, and the qualified product converging mechanism, and processes that require slow and paused movement of the loading part, such as the extrusion mechanism and the cleaning mechanism, can be carried out in parallel, avoiding mutual restraint and waiting during the operation of each mechanism, which is beneficial to reducing the idle time of the equipment and further improving the leak detection efficiency of the equipment.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. The feeding mechanism delivers the hose output from the filling and sealing equipment to the output line, and the hose is transported through the conveyor line. The hose is first squeezed by the squeezing mechanism, and then the imaging mechanism obtains the image of the squeezed hose and uses it to determine whether the hose is leaking. Based on the judgment structure, the rejection mechanism removes unqualified leaking hoses from the conveyor line, realizing automatic detection and rejection of leaking hoses, effectively improving the efficiency of hose leak detection.

[0041] 2. By setting up two loading conveyor belts and using them to cooperate with each other, it is convenient for the loading mechanism, rejecting mechanism and other processes that require the loading part to move intermittently and quickly to be carried out simultaneously with the extrusion mechanism, cleaning mechanism and other processes that require the loading part to pause and operate slowly, which is beneficial to reducing the idle time of the equipment and improving the overall leak detection efficiency of the equipment for hoses.

[0042] 3. By setting a blocking piece on the top of the receiving conveyor belt of the qualified product conveying mechanism, the blocking piece is used to limit the hoses at adjacent workstation slots from falling into the corresponding receiving conveyor belts at the same time, so that the adjacent receiving conveyor belts staggeredly receive the hoses falling from the corresponding workstation slots, which is conducive to the orderly flow of the hoses into the merging conveyor belt and limits the squeezing and blockage of subsequent hoses when flowing into the merging conveyor belt.

[0059] The following is combined with Figure 1-13 This application is further described in detail.

[0060] The present application embodiment discloses a leak detection device for an ointment packaging hose, referring to Figure 1 , including a frame, on which are arranged a conveying line 1, a feeding mechanism 2, an extrusion mechanism 3, a visual mechanism 4, a rejecting mechanism 5, a qualified product conveying mechanism 6 and a cleaning mechanism.

[0061] Reference Figures 2 to 4 Conveyor line 1 is used to transport hoses. Specifically, conveyor line 1 includes a frame supporting two parallel loading conveyor belts 11. Each loading conveyor belt 11 is equipped with three loading sections 12. Each loading section 12 includes several station slots 121 for receiving hoses. The bottom of each station slot 121 is connected to the conveying surface of the corresponding conveyor line 1, and the ends of each station slot 121 extend to opposite sides of the two loading conveyor belts 11.

[0062] Reference Figure 1 and Figure 5 The feeding mechanism 2 is arranged close to the conveyor line 1 and is used to transfer the hose output from the output end of the filling and sealing machine into the station slot 121 located on the conveyor line 1.

[0063] The feeding mechanism 2 includes two first feeding conveyor belts 21 and two second feeding conveyor belts 22. Both the first feeding conveyor belt 21 and the second feeding conveyor belt 22 are used to convey hoses, and the conveying directions of both are perpendicular to the conveying direction of the loading conveyor belt 11.

[0064] Two first loading conveyor belts 21 are arranged side by side, and the output ends of both first loading conveyor belts 21 are located near the conveyor line 1. Two second loading conveyor belts 22 are arranged side by side, and the input ends of the two second loading conveyor belts 22 are connected to the two output ends of the filling and sealing equipment, respectively, for receiving the hoses transmitted from the filling and sealing equipment. The output ends of the two second loading and charging conveyor belts 11 are connected to the input ends of the two first loading conveyor belts. In this embodiment, both the first loading conveyor belt 21 and the second loading conveyor belt 22 are composed of two conveyor belts arranged one above the other, with a conveying gap formed between the two conveyor belts for the hoses to enter.

[0065] Through the setting of the feeding mechanism 2, when the material is subsequently fed through the feeding mechanism 2, the loading conveyor belt 11 drives the loading part 12 to move to the feeding mechanism 2 area, and makes the vacant workstation slot 121 opposite to the output end of the first feeding conveyor belt 21, and the output hose of the discharge end of the filling and sealing equipment is sent to the corresponding workstation slot 121 through the corresponding second feeding conveyor belt 22 and the first feeding conveyor belt 21 to complete the feeding of the hose.

[0066] By setting up two first feeding conveyor belts 21, the loading conveyor belt 11 can move the distance between the two work station slots 121 in a single time, so that the two work station slots 121 are respectively opposite to the output ends of the two first feeding conveyor belts 21, and then the two first feeding conveyor belts 21 respectively deliver the hoses to the opposite work station slots 121, so that the loading of two hoses can be completed in a single time, which effectively improves the loading efficiency of the hoses.

[0067] By setting up two second feeding conveyor belts 22, after the hose first transmitted from the discharge end of the filling and sealing equipment is transmitted to the corresponding second feeding conveyor belt 22, the second feeding conveyor belt 22 will pause to transport the hose to the first feeding conveyor belt 21. After the hoses at the two discharge ends of the filling and sealing equipment are transported to the second feeding conveyor belt 22, the two second feeding conveyor belts 22 will simultaneously transport the hoses to the corresponding first feeding conveyor belt 21, and the two first feeding conveyor belts 21 will simultaneously transport the hoses to the relative workstation slots 121, realizing the simultaneous loading of the two hoses, reducing the situation where the workstation slots 121 appear empty during the loading process due to inconsistent output time of the hoses from the discharge end of the filling and sealing equipment.

[0068] Reference Figure 1 and Figure 6 The extrusion mechanism 3 is located downstream of the feeding mechanism 2 and is used to extrude the hose located in the work station slot 121.

[0069] The extrusion mechanism 3 includes an extrusion bracket 31 supported above the conveyor line 1, and the extrusion bracket 31 is provided with a plurality of extrusion parts 32 corresponding to the plurality of station slots 121 of the loading part 12. The extrusion part 32 is vertically arranged and is located above the conveying path of the station slots 121. The extrusion part 32 includes a pressure rod 321 and a pressure head 322, and the pressure head 322 is connected to the bottom end of the pressure rod 321. The extrusion bracket 31 is provided with a lifting drive member 33 corresponding to the extrusion part 32, and the lifting drive member 33 is used to drive the extrusion part 32 to rise and fall vertically. Specifically, the lifting drive member 33 includes a lifting cylinder vertically installed on the extrusion bracket 31, and the end of the lifting cylinder piston rod is connected to the top of the pressure rod 321 corresponding to the extrusion part 32.

[0070] Subsequently, the loading conveyor belt 11 transports the loading part 12 containing the hose to be tested to the extrusion mechanism 3, and after the several work station slots 121 on the loading part 12 are aligned with the several extrusion parts 32 on the extrusion mechanism 3, the lifting drive part 33 drives the corresponding extrusion part 32 to move downward until the pressure head 322 of the extrusion part 32 presses the hose in the relative work station slot 121 and maintains it for 2 seconds. Then, the lifting drive part 33 drives the extrusion part 32 away from the hose in the work station slot 121, and uses the extrusion part 32 to squeeze the hose in the work station slot 121 so that the paste in the leaking hose can overflow from the leak.

[0071] Reference Figure 3 and Figure 6Two support rails 10 are laid on the upper surface of the frame of the conveyor line 1; rollers 122 are rotatably connected to the opposite ends of the work station slot 121, and the rotation axis of the rollers 122 is set perpendicular to the conveying direction of the conveyor line 1. When the loading conveyor belt 11 drives the work station slot 121 to move above the conveyor line 1, the rollers 122 at the opposite ends of the work station slot 121 respectively abut against the two support rails 10. The cooperation between the rollers 122 at the two ends of the work station slot 121 and the two support rails 10 is used to support the work station slot 121, which is beneficial to prevent the subsequent work station slot 121 from moving downward due to the squeezing of the hose by the squeezing part 32, so that the squeezing part 32 can better squeeze the hose located in the work station slot 121.

[0072] Reference Figure 1 and Figure 7 The visual mechanism 4 is located downstream of the extrusion mechanism 3 and is used to capture images of the extruded hose and determine whether it is leaking based on the images. Specifically, the visual mechanism 4 includes a visual camera 41 and a controller. The visual camera 41 is supported above the conveyor line 1 via a mounting bracket 40 and is positioned relative to the conveying path of the station slot 121 of the loading conveyor belt 11. The visual camera 41 is electrically connected to the controller and is used to capture images of the hose within the station slot 121 and feed them back to the controller. The controller is used to determine whether the hose within the station slot 121 is leaking based on the images fed back by the visual camera 41.

[0073] Reference Figure 1 and Figure 8 The rejection mechanism 5 is located downstream of the visual mechanism 4 and is used to reject the leaking hose from the workstation slot 121 according to the judgment result of the controller of the visual mechanism 4.

[0074] Reference Figure 8 and Figure 9 The rejecting mechanism 5 includes a pushing part 51 and a collecting box 52; the pushing part 51 and the collecting box 52 are respectively located on opposite sides of the conveyor line 1 and the pushing part 51 and the collecting box 52 are arranged opposite to each other; the pushing part 51 includes a pushing bracket 511 supported on the side of the conveyor line 1, and the side of the conveyor line 1 facing the pushing bracket 511 is supported with two pushing blocks 512, and the pushing bracket 511 is supported with two pushing driving components 513 corresponding to the two rejecting blocks. The pushing driving component 513 is driven and connected to the corresponding pushing blocks 512, and is used to drive the pushing blocks 512 to move horizontally toward or away from the conveyor line 1. Specifically, the pushing driving component 513 includes a pushing cylinder installed on the pushing bracket 511, and the pushing cylinder piston rod is connected to the corresponding pushing block 512, and the pushing cylinder is electrically connected to the controller.

[0075] When the loading conveyor belt 11 transports the work station slot 121 containing the leaking hose to a position opposite to the pushing block 512, the controller controls the pushing cylinder according to the judgment result to drive the pushing block 512 to move toward the work station slot 121 of the loading conveyor belt 11, and then uses the pushing block 512 to push the leaking hose in the work station slot 121 from the work station slot 121 to the collection box 52, thereby realizing the automatic removal of the leaking hose.

[0076] Reference Figure 2 and Figure 10 The end of the conveyor line 1 is sleeved with a deflector 13, and the inner contour of the deflector 13 matches the contour of the ends of the two loading conveyor belts 11. The ends of the two loading conveyor belts 11 are both located inside the deflector 13; the bottom end of the deflector 13 extends to the bottom of the conveyor line 1. When the loading conveyor belt 11 conveys the station slot 121 into the deflector 13, the slot of the station slot 121 is set close to the inner wall of the deflector 13; the deflector 13 cooperates with the two loading conveyor belts 11 to limit the loading conveyor belt 11 from driving the station slot 121 to move to the end of the conveyor line 1, so that the hose in the station slot 121 slides out of the station slot 121, so that the loading conveyor belt 11 can drive the station slot 121 to move the loaded hose to the bottom of the conveyor line 1.

[0077] Reference Figure 10 and Figure 11 The lower part of the guide cover 13 is in the shape of a mesh plate on the side opposite to the loading conveyor belt 11, which is beneficial to reduce the paste leaked from the leakage hose in the station slot 121 adhering to the guide cover 13 when the station slot 121 moves to the bottom of the loading conveyor belt 11.

[0078] Reference Figure 10 and Figure 12 The qualified product conveying mechanism 6 is located downstream of the rejection mechanism 5 and below the conveyor line 1. It is used to receive qualified hoses from the conveyor belt 61 and convey them to the next process. The qualified product conveying mechanism 6 includes a merging conveyor belt 62 and two receiving conveyor belts 61. The conveying directions of the merging conveyor belt 62 and the two receiving conveyor belts 61 are both arranged perpendicular to the conveying direction of the conveyor line 1.

[0079] Two guide plates 63 are provided on the merging conveyor belt 62 . The two guide plates 63 are located on opposite sides of the conveying surface of the merging conveyor belt, and the distance between the two guide plates 63 gradually decreases from the input end of the merging conveyor belt 62 toward the output end of the merging conveyor belt 62 .

[0080] Two receiving conveyor belts 61 are located below the two loading conveyor belts 11 of conveyor line 1. These two receiving conveyor belts 61 are arranged side by side and below the bottom end of the deflector 13. They are used to receive the hoses that fall out of the work slots 121 after they are removed from the bottom end of the deflector 13. The output ends of the two receiving conveyor belts 61 are connected to the input end of the converging conveyor belt 62.

[0081] The qualified product conveying mechanism 6 also includes a blocking part 64 and a blocking drive part 65. The blocking part 64 blocks the receiving conveyor belt 61 near the air deflector 13. The blocking drive part 65 includes a blocking cylinder, which is installed at the bottom of the air deflector 13. The blocking cylinder piston rod is connected to the blocking part 64 and is used to drive the blocking part 64 to slide in the horizontal direction.

[0082] When the loading conveyor belt 11 drives the two work station slots 121 to move out from the bottom end port of the air deflector 13 and move above the two receiving conveyor belts 61, the hose in the work station slot 121 away from the air deflector 13 falls onto the receiving conveyor belt 61 away from the air deflector 13, and the hose in the work station slot 121 close to the air deflector 13 is blocked by the blocking member 64; when the receiving conveyor belt 61 away from the air deflector 13 receives the hose falling from the corresponding work station slot 121 and transports it to the converging conveyor belt 62, the blocking member 64 is driven to slide by the blocking drive member 65 to open the receiving conveyor belt 61 close to the air deflector 13, so that the hose in the work station slot 121 opposite to it falls onto the receiving conveyor belt 61 close to the air deflector 13. Through the above arrangement, the two receiving conveyor belts 61 are staggered to receive the hoses falling out of the workstation slot 121, which is beneficial to avoid the two receiving conveyor belts 61 simultaneously conveying the hoses to the merging conveyor belt 62, causing blockage when the merging conveyor belt 62 conveys the hoses, which is beneficial to the merging conveyor belt 62 to convey the hoses in an orderly manner.

[0083] Reference Figure 13 and Figure 14 The cleaning mechanism 7 is located downstream of the qualified product conveying mechanism 6, and the cleaning mechanism 7 is located below the conveying line 1. The cleaning mechanism 7 is used to clean the workstation slot 121 loaded with the leaking hose according to the judgment result of the visual mechanism 4.

[0084] The cleaning mechanism 7 includes a cleaning box 71. A notch 711 is provided on the top of the cleaning box 71 for the conveyor line 1 to be inserted. The notch 711 of the cleaning box 71 is sleeved on the bottom of the conveyor line 1. The cleaning box 71 is provided with a plurality of cleaning sections 72 corresponding to the plurality of station slots 121 of the loading section 12. The cleaning section 72 includes two cleaning pipes 721 vertically supported. The cleaning pipe 721 is connected to a water supply pipe 722 and an air supply pipe 723. The water supply pipe 722 and the air supply pipe 723 are connected to a water source and an air source, respectively. The water supply pipe 722 and the air supply pipe 723 are respectively installed with a water supply control switch and an air supply control switch. Both the water supply control switch and the air supply control switch are electrically connected to the controller of the visual mechanism 4.

[0085] Subsequently, when the loading conveyor 11 drives the loading section 12 into the cleaning box 71 and positions the plurality of workstations 121 of the loading section 12 opposite the plurality of cleaning sections 72, the controller, based on the image recognition results, first controls the water supply control switch of the corresponding cleaning pipe 721 to connect the cleaning pipe 721 to the water source, thereby spraying water through the cleaning pipe 721 to flush the workstation 121 loaded with the leaking hose. The controller then controls the air supply control switch to connect the cleaning pipe 721 to the air source to spray air through the cleaning pipe 721 to dry the workstation 121 loaded with the leaking hose, thereby cleaning the workstation 121 and reducing the possibility of leaking paste adhering to the workstation 121, which could interfere with the imaging mechanism's acquisition and judgment of the next batch of hose images. A drain port 710 is provided at the bottom of the cleaning box 71 to facilitate the discharge of cleaning wastewater.

[0086] When one loading portion 12 of a set of feeding conveyor belts 11 is located at the feeding mechanism 2, the remaining two loading portions 12 of the set of feeding conveyor belts 11 are located at the visual mechanism 4 and the rejection mechanism 5, and the other is located at the qualified product conveying mechanism 6; at the same time, one loading portion 12 of another set of feeding conveyor belts 11 is located at the extrusion mechanism 3, and one loading portion 12 is located at the cleaning mechanism 7. Through the above arrangement, the two feeding conveyor belts 11 cooperate with each other, which is conducive to the simultaneous and parallel development of the processes such as the feeding mechanism 2, the visual mechanism 4 and the qualified product conveying mechanism 6 that require the intermittent and slow movement of the feeding portion 12 and the processes such as the extrusion mechanism 3 and the cleaning mechanism 7 that require the slow and paused movement of the feeding portion 12, thereby reducing the mutual restraint and waiting during the operation of each mechanism, thereby reducing the idle time of the equipment and improving the leak detection efficiency of the equipment.

[0087] The implementation principle of the embodiment of the present application is that when leak detection is performed on a hose, the feeding mechanism 2 conveys the hose discharged from the discharge end of the filling and sealing device to the station slot 121 of the loading conveyor belt 11 corresponding to the loading part 12;

[0088] When the loading conveyor belt 11 drives the loading part 12 to move to the extrusion mechanism 3, the extrusion mechanism 3 squeezes the hose in the station slot 121 so that the paste in the leaking hose leaks out through the leaking point;

[0089] When the loading conveyor belt 11 drives the loading part 12 to move to the visual mechanism 4, the visual mechanism 4 obtains an image of the station slot 121 of the loading part 12 and determines whether the hose is leaking based on the obtained image;

[0090] When the loading conveyor belt 11 drives the loading part 12 to move to the rejecting mechanism 5, the rejecting mechanism 5 rejects the leaking hose from the station slot 121 according to the judgment result of the visual mechanism 4;

[0091] When the loading conveyor belt 11 drives the loading part 12 to move to the qualified product conveying mechanism 6, the qualified product conveying mechanism 6 receives the qualified hose and conveys it to the subsequent process;

[0092] When the loading conveyor belt 11 drives the loading portion 12 to move to the cleaning mechanism 7 , the cleaning mechanism 7 cleans the station slot 121 where the leaking hose has been loaded.

[0093] This application can realize the leakage detection and rejection of the hose, effectively improving the leak detection efficiency of the hose.

[0094] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
