Description

Technical Field

[0001] The invention relates to the technical field of bottle body detection, and in particular to an adaptive mixed-production bottle defect detection system. Background Art

[0002] Glass bottles, milk glass bottles and ceramic bottles are commonly used white wine packaging bottles with a wide range of applications and various specifications. Bottles of various specifications need to be inspected for defects to prevent leakage. In the prior art, one inspection line is usually used for one bottle. This method requires the establishment of multiple different inspection lines, which increases the workload and production costs. When multiple bottles are mixed, this single-line inspection method cannot meet the needs of multiple bottles. In addition, before inspecting multiple mixed bottles, the bottles need to be sorted to ensure the order of subsequent inspections. However, the currently commonly used bottle sorting devices cannot sort bottles of different specifications at the same time, which will also increase the workload and production costs when the bottles are mixed. Summary of the invention

[0003] In order to solve the technical problem in the above background technology that the bottle unscrambling device and the bottle inspection line cannot be automatically adjusted according to different bottles when mixed production of multiple bottles is carried out, the present invention provides an adaptive mixed production bottle defect detection system.

[0004] The technical solution of the present invention is as follows:

[0005] An adaptive mixed-production bottle defect detection system comprises a main conveyor belt, and a mixed-production bottle sorting module, a bottleneck centering detection module, an adaptive bottle mouth detection module, a rejection module and a bottle receiving module which are sequentially arranged along the conveying direction thereof.

[0006] The mixed production bottle unscrambling module includes an auxiliary conveyor belt arranged in parallel on the outside of the head end of the main conveyor belt, and a conveying channel arranged above the main conveyor belt and the auxiliary conveyor belt and corresponding to the main conveyor belt and the auxiliary conveyor belt one by one. The end of the conveying channel is provided with a bottle stopping mechanism capable of limiting or releasing the bottles to be inspected; the mixed production bottle unscrambling module also includes a transfer track arranged at the end of a plurality of conveying channels, which is configured to move the bottles to be inspected transmitted from the end of the auxiliary conveyor belt to the main conveyor belt.

[0007] The bottleneck centering detection module includes a centering mechanism arranged front and back along the conveying direction of the main conveyor belt and a bottleneck detection machine with adjustable vertical height. The centering mechanism includes centering units arranged on both sides of the main conveyor belt, which are configured to push the bottles to be inspected that deviate from the center of the main conveyor belt to the middle of the main conveyor belt. The bottleneck detection machine is configured to complete the bottleneck defect detection work of the bottles to be inspected at different heights.

[0008] The adaptive bottle mouth detection module includes a camera rotation following detection machine arranged above the main conveyor belt, and the camera rotation following detection machine is vertically height adjustable, and is configured to complete the bottle mouth defect detection work of bottles to be inspected at different heights.

[0009] The rejection module is configured to remove defective bottles from the main conveyor belt, and the bottle collection module is configured to complete the collection of qualified bottles.

[0010] Mixed bottles of different specifications that need to be inspected are placed in the conveying channels, and the bottles to be inspected are transported and inspected for defects in various parts of the bottles. Before inspection, various mixed bottles are pre-processed by the mixed bottle unscrambling module. Under the action of the bottle stop mechanism, the bottles to be inspected in different conveying channels enter the transfer track in sequence, and under the action of the transfer track, the bottles to be inspected from the conveying channels are moved to the main conveyor belt. Subsequently, the bottles to be inspected are inspected for defects in the bottleneck and the bottle mouth in sequence. When entering the bottleneck centering detection module, the bottles to be inspected that deviate from the center of the main conveyor belt are first pushed to the middle of the main conveyor belt under the action of the centering mechanism to ensure that the bottles to be inspected can smoothly enter the detection range of the bottleneck detection machine. At the same time, the bottleneck detection machine is raised and lowered according to the height of the bottles to be inspected to achieve the optimal detection height. After completing the bottleneck defect detection, the bottle to be inspected begins the bottle mouth inspection. The camera in the adaptive bottle mouth inspection module rotates and follows the inspection machine to adjust to the appropriate height according to the height of the bottle to be inspected, and moves linearly with the bottle to be inspected. After the inspection is completed, the camera rotates and follows the inspection machine to return to the initial position to wait for the next bottle. If the bottle fails the inspection, it will be rejected by the rejection module, and the qualified bottle will be collected by the bottle collection module.

[0011] Furthermore, the widths of the plurality of conveying channels can be adjusted independently, and different conveying channels can adapt to bottles of different specifications. The independent adjustments do not affect each other, so that the bottles in each conveying channel can be different, and when there are more bottles of a certain type, the number of conveying channels matching the bottles can be increased. The usage is flexible and adaptable.

[0012] As a preferred embodiment, the end of the conveying channel away from the bottle stopping mechanism is also provided with a prompting mechanism that can prompt when the bottles in the conveying channel are full. The setting of the prompting mechanism can timely obtain the number of bottles in the conveying channel to determine whether the limit has been reached, without the need to manually observe the number of bottles in each conveying pass with the naked eye, saving time and effort and improving work efficiency. If the number of bottles in a certain channel is full, the bottle stopping mechanism at one end of the conveying channel can be controlled first to release the bottles.

[0013] Specifically, the bottle stopping mechanism includes vertical plates arranged at two sides of the end of the conveying channel, and air bags are arranged on the opposite sides of the two vertical plates; the bottle stopping mechanism also includes an air pump capable of inflating or deflating the air bags. When the air bags are inflated, the bottles at the end of the conveying channel can be clamped to restrict their further movement. When the air bags are gradually deflated, the clamped bottles are released. The air bags restrict the movement of the bottles to be inspected without causing damage to the bottles.

[0014] Preferably, the distance between the two vertical plates is adjustable. If the distance between the two vertical plates is too large, the bottle cannot be tightened even if the airbag is fully inflated. If the distance between the two vertical plates is too small, the bottle to be inspected cannot pass through the bottle stop mechanism smoothly. Flexible adjustment of the distance between the two vertical plates can ensure that the bottle stop mechanism can meet the needs of bottles of different specifications and adapt to different transportation conditions.

[0015] Further preferably, a plurality of airbags are arranged vertically and linearly, which not only ensures that the clamping range of the airbags can cover bottles of different heights, but also prevents the bottle from tilting due to uneven force when clamping the bottle.

[0016] In order to ensure that mixed bottles of different specifications can pass through the centering mechanism smoothly and be transported along the middle of the main conveyor belt, the two centering units are configured to be able to slide synchronously in opposite directions perpendicular to the conveying direction of the main conveyor belt.

[0017] In order to facilitate the storage of bottles to be inspected and for different bottles to be inspected to enter different conveying channels respectively, the mixed production bottle sorting module also includes a bottle storage platform arranged at the front end of the main conveyor belt and the auxiliary conveyor belt. Some bottles to be inspected are temporarily stored on the bottle storage platform for convenient transportation. In addition, there is a smooth transition between the storage platform and the main conveyor belt and the auxiliary conveyor belt to avoid the situation where bottles fall over when the inspection platform is pushed into the conveying channel.

[0018] Specifically speaking, the transfer track includes guardrails arranged on both sides of the main conveyor belt, one end of each of the guardrails is connected to the outer edge of the outermost auxiliary conveyor belt, and the other end gradually approaches and closes to connect to the outer edge of the main conveyor belt. It is ensured that all platforms to be inspected in all conveying channels can enter the transfer track. The guardrails on both sides are gradually closed, so that the bottles to be inspected in the transfer track can smoothly and only enter the main conveyor belt, ensuring the smooth progress of subsequent bottle defect detection. At the same time, the setting of the guardrails can also prevent the bottles from tilting or falling.

[0019] As a preferred embodiment, emergency stop buttons are provided at both ends of the main conveyor belt. When a module on the main conveyor belt fails or an accident occurs to the bottle being transported for inspection, the transportation of the main conveyor belt can be suspended in time and the faulty part can be repaired.

[0020] Through the above design, the beneficial effects of the adaptive mixed production bottle defect detection system of the present invention are:

[0021] The entire system can complete bottle defect detection for mixed-production bottles of different specifications, and each module can adapt to changes in bottle specifications and make adjustments. There is no need to add multiple inspection lines, thereby improving bottle inspection efficiency.

[0022] 2. Through the mixed production bottle unscrambling module, various bottles can be unscrambled at the same time. The same conveying channel can transport bottles of various specifications. The cooperation of the prompting mechanism and the bottle stopping mechanism ensures that the bottles in multiple conveying channels can be discharged in an orderly manner, avoiding the disorder of bottle discharge and bottle accumulation, and improving the unscrambling efficiency of mixed production bottles. Moreover, the setting of the transfer track ensures that the bottles in all conveying channels can smoothly enter the main conveyor belt, ensuring the smooth progress of subsequent bottle defect detection.

[0023] , through the setting of the centering mechanism, it is ensured that all kinds of bottles to be inspected can be transported along the middle of the main conveyor belt, ensuring that the bottles to be inspected can smoothly enter the detection range of the bottleneck inspection machine. The bottleneck inspection machine can be raised and lowered according to the height of the bottles to be inspected to complete the bottleneck defect detection work of the bottles to be inspected at different heights.

[0024] , the camera in the adaptive bottle mouth detection module rotates and follows the detection machine to adjust to the appropriate height according to the height of the bottle to be inspected, and moves linearly with the bottle to be inspected. After the inspection is completed, the camera rotates and follows the detection machine to return to the initial position to wait for the next bottle. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0037] Example: Combination Figures 1 to 8 This embodiment provides an adaptive mixed-production bottle defect detection system, including a main conveyor belt, and a mixed-production bottle sorting module 1, a bottleneck centering detection module 2, an adaptive bottle mouth detection module 3, a rejection module 4 and a bottle receiving module 5 arranged in sequence along the conveying direction thereof. The structure of the detection system (the above-mentioned adaptive mixed-production bottle defect detection system) is described in detail below.

[0038] As a preferred embodiment, emergency stop buttons are provided at both ends of the main conveyor belt. When a module on the main conveyor belt fails or an accident occurs to the bottle being transported for inspection, the transportation of the main conveyor belt can be suspended in time and the faulty part can be repaired.

[0039] In this embodiment, the mixed production bottle sorting module 1 includes an auxiliary conveyor belt arranged in parallel on the outside of the head end of the main conveyor belt, and a conveying channel 11 arranged above the main conveyor belt and the auxiliary conveyor belt and corresponding to the main conveyor belt and the auxiliary conveyor belt one by one.

[0040] The main conveyor belt and the auxiliary conveyor belt have a height of 1000 mm, which is ergonomic and convenient for placing and taking bottles, as well as for operators to observe or maintain the entire system.

[0041] Furthermore, the widths of the plurality of conveying channels 11 can be adjusted independently, and different conveying channels 11 can adapt to bottles of different specifications. The independent adjustments do not affect each other, so that the bottles in each conveying channel 11 can be different, and when there are more bottles of a certain type, the number of conveying channels 11 that match the bottles can be increased. The usage is flexible and adaptable.

[0042] Reference Figure 5 In a specific implementation, baffles 17 are provided on both sides of several of the conveying channels 11, and an adjustment mechanism is provided above the two baffles 17, which can independently adjust the distance between the baffles 17 on both sides of different conveying channels 11. The mixed production bottle unscrambling module 1 also includes a fixed frame 18 arranged above the main conveyor belt and the auxiliary conveyor belt, and several adjustment mechanisms are fixedly connected to the fixed frame 18 to improve the integrity of the structure.

[0043] The adjustment mechanism includes adjustment components 15 respectively connected to both ends of the baffle 17. The baffle 17 includes a first strip plate arranged along the conveying direction of the conveying channel 11, and the length of the first strip plate is consistent with the length of the conveying channel 11. Second strip plates connected to two adjustment components 15 are respectively arranged at both ends above the first strip plate, and the first strip plate and the second strip plate are integrally formed and arranged on the same plane.

[0044] Specifically, the second strip is provided with a plurality of through holes, the number of which is consistent with the number of the transmission channels 11, and the adjustment assembly 15 includes a plurality of lead screws 151 arranged perpendicular to the conveying direction of the transmission channel 11, the number of which is consistent with the number of the transmission channels 11, and the one-to-one correspondence. As for the adjustment assembly 15 of a single transmission channel 11, the lead screw 151 sequentially passes through two corresponding through holes on the second strip on both sides of the transmission channel 11, and two transmission members 152 are sleeved on the front and rear of the outer ring of the lead screw 151, and the two transmission members 152 are respectively fixedly connected to the second strip on both sides of the transmission channel 11, and the two transmission members 152 are configured to be able to synchronously move in opposite directions along the length direction of the lead screw 151 when the lead screw 151 rotates.

[0045] In order to enable the two ends of the baffle 17 to move synchronously, a synchronous belt is provided between the lead screws 151 in the two sets of adjustment components 15. When one of the lead screws 151 is rotated, the other lead screw 151 rotates synchronously.

[0046] The adjustment mechanism further includes a handle 153 disposed at one end of the lead screw 151 to facilitate an operator to rotate the lead screw 151 .

[0047] In order to facilitate the storage of bottles to be inspected and for different bottles to be inspected to enter different conveying channels 11 respectively, the mixed production bottle sorting module 1 also includes a bottle storage platform 16 arranged at the front end of the main conveyor belt and the auxiliary conveyor belt. The length of the bottle storage platform 16 along the conveying direction of the conveying channel 11 is not less than 250 mm. Some bottles to be inspected are temporarily stored on the bottle storage platform 16 for convenient transportation. In addition, there is a smooth transition between the storage platform and the main conveyor belt and the auxiliary conveyor belt to avoid the situation where bottles fall over when the inspection platform is pushed into the conveying channel 11.

[0048] A bottle stopping mechanism 12 is provided at the end of the conveying channel 11 for limiting or releasing the bottles to be inspected.

[0049] Specifically, the bottle stopping mechanism 12 includes vertical plates 121 disposed at both sides of the end of the conveying channel 11, and air bags 122 are disposed on the opposite sides of the vertical plates 121; the bottle stopping mechanism 12 also includes an air pump capable of inflating or deflating the air bags 122. When the air bags 122 are inflated, the bottle at the end of the conveying channel 11 can be clamped to restrict its further movement. When the air bags 122 are gradually deflated, the clamped bottle is released, and the air bags 122 are used to restrict the movement of the bottles to be inspected without causing damage to the bottles.

[0050] Preferably, the distance between the two vertical plates 121 is adjustable. If the distance between the two vertical plates 121 is too large, the bottle cannot be tightened even if the airbag 122 is fully inflated. If the distance between the two vertical plates 121 is too small, the bottle to be inspected cannot pass smoothly through the bottle stopping mechanism 12. Flexible adjustment of the distance between the two vertical plates 121 can ensure that the bottle stopping mechanism 12 can meet the needs of bottles of different specifications and adapt to different transportation conditions.

[0051] Further preferably, a plurality of the airbags 122 are arranged vertically and linearly, which not only ensures that the clamping range of the airbags 122 can cover bottles of different heights, but also prevents the bottle from tilting due to uneven force when clamping the bottle.

[0052] Reference Figure 5 , 6 In order to synchronously adjust the spacing between the two vertical plates 121 and the two baffles 17, the upper ends of the two vertical plates 121 are connected to the lead screw 151 through a linkage. The two linkages are configured to synchronously move in opposite directions along the length direction of the lead screw 151 when the lead screw 151 rotates.

[0053] Furthermore, the linkage member includes a connecting plate 123 horizontally arranged above the screw 151 and parallel to the conveying direction of the conveying channel 11, a linkage plate 124 is provided on the side of the connecting plate 123 facing the conveying channel 11, the linkage plate 124 is sleeved on the outer circle of the screw 151, and a triangular plate 125 is provided below the end of the connecting plate 123 away from the linkage plate 124, and the upper end of the vertical plate 121 is fixedly connected to the connecting plate 123 through the triangular plate 125.

[0054] The fixed frame 18 includes a connecting rod mounted above the main conveyor belt and the auxiliary conveyor belt, and the connecting rod is arranged perpendicular to the conveying direction of the main conveyor belt. The linkage member also includes a slider 126 arranged below the connecting plate 123, and the slider is slidably connected to the connecting rod, and the connecting rod provides support and guidance for the linkage member.

[0055] To ensure that the bottle stopping mechanism 12 can clamp the passing bottle to be inspected in time, the bottle stopping mechanism 12 also includes a detection mechanism that can detect whether the bottle has arrived. The detection mechanism includes a photoelectric sensor arranged on the side of the vertical plate 121 close to the bottle incoming direction of the transmission channel.

[0056] The mixed production bottle sorting module 1 also includes an air pump for inflating and deflating the airbag 122, and a control module capable of controlling the action of the air pump. When a bottle passes through the photoelectric sensor, the control module can receive the signal of the photoelectric sensor, and judge the time when the bottle reaches the position of the airbag 122 according to the distance between the photoelectric sensor and the airbag 122 and the conveying speed of the bottle. When the bottle reaches the position of the airbag 122, the control module controls the air pump to inflate the airbag 122 to clamp the bottle and restrict it from moving further. At the same time, the airbags 122 in the plurality of conveying channels 11 are sequentially deflated to achieve the sequential discharge of bottles of different specifications and avoid confusion in the discharge of bottles.

[0057] As a preferred embodiment, the end of the conveying channel 11 away from the bottle stopping mechanism 12 is also provided with a prompting mechanism 14 that can prompt when the bottles in the conveying channel 11 are full. The setting of the prompting mechanism 14 can timely obtain the number of bottles in the conveying channel 11 to determine whether the limit has been reached, without the need to manually observe the number of bottles in each conveying pass with the naked eye, saving time and effort and improving work efficiency. If the number of bottles in a certain channel is full, the bottle stopping mechanism 12 at one end of the conveying channel 11 can be controlled first to release the bottles.

[0058] The control module is in communication with the prompt mechanism 14 . When a conveying channel 11 is full of bottles, the control module controls the airbag 122 of the conveying channel 11 to deflate, and gives priority to releasing the bottles in the conveying channel 11 .

[0059] The mixed production bottle unscrambling module 1 further comprises a transfer track 13 arranged at the end of the plurality of conveying channels 11, which is configured to move the bottles to be inspected transmitted from the end of the auxiliary conveyor belt to the main conveyor belt.

[0060] Specifically speaking, the transfer track 13 includes fences 131 arranged on both sides of the main conveyor belt, one end of each of the fences 131 is connected to the outer edge of the outermost auxiliary conveyor belt, and the other end gradually approaches and closes to connect to the outer edge of the main conveyor belt. It is ensured that all platforms to be inspected in the conveying channel 11 can enter the transfer track 13. The fences 131 on both sides are gradually closed, so that the bottles to be inspected in the transfer track 13 can smoothly and only enter the main conveyor belt, ensuring the smooth progress of subsequent bottle defect detection. At the same time, the setting of the fences 131 can also prevent the bottles from tilting or falling.

[0061] In this embodiment, the bottleneck centering detection module 2 includes a centering mechanism arranged front and back along the conveying direction of the main conveyor belt and a bottleneck detection machine 22 with adjustable vertical height. The centering mechanism includes a centering unit 21 arranged on both sides of the main conveyor belt, which is configured to push the bottle body to be inspected that deviates from the center of the main conveyor belt to the middle of the main conveyor belt.

[0062] In order to ensure that mixed bottles of different specifications can pass through the centering mechanism smoothly and be transported along the middle of the main conveyor belt, the two centering units 21 are configured to be able to slide synchronously in opposite directions perpendicular to the conveying direction of the main conveyor belt.

[0063] Reference Figure 7 The centering mechanism also includes a mounting frame 23 arranged on both sides of the main conveyor belt, and the centering unit 21 includes a sliding frame 211 arranged on the upper side of the mounting frame 23 and capable of sliding perpendicular to the conveying direction of the conveyor belt. A side of the sliding frame 211 close to the conveyor belt is arranged along the conveying direction of the conveyor belt. The outer ring sleeves of the plurality of centering rollers 212 are provided with centering belts 213, and the centering belts 213 are configured to rotate at the same speed as the conveyor belt. Under the joint action of the two sets of centering belts 213, the bottle body to be inspected that deviates from the center of the main conveyor belt can be pushed to the middle of the main conveyor belt.

[0064] The centering mechanism also includes a driving unit capable of driving the two sliding frames 211 to slide synchronously in opposite directions perpendicular to the conveying direction of the conveyor belt.

[0065] The bottleneck detection machine 22 is configured to be able to complete the bottleneck defect detection work of bottles to be inspected at different heights. Specifically, the bottleneck centering detection module 2 also includes a fixed frame 18 arranged on one side of the main conveyor belt and located at the rear side of the centering mechanism. A vertical slide rail is provided on the side close to the conveyor belt. The bottleneck detection machine 22 is slidably connected to the slide rail through a lifting frame. The lifting frame can be lifted up and down according to the height of the bottle to be inspected transported by the transfer track 13 to adjust to a suitable height. As for the specific structure of the bottleneck detection machine 22, reference can be made to the light source, reflective imaging structure, image processing device, etc. disclosed in the patent document with application number CN201720728586.2 previously applied by the applicant, and no unnecessary elaboration will be made here.

[0066] An overheight detection mechanism is also connected to the side of the lifting frame facing the centering mechanism, through which it can be detected whether the height of the bottle to be inspected is consistent with the height adjusted by the bottleneck detection machine 22. If the bottle to be inspected is too high, the conveyor belt needs to be stopped to avoid collision between the bottle to be inspected and the bottleneck detection machine 22.

[0067] In this embodiment, the adaptive bottle mouth detection module 3 includes a camera rotation following detection machine 31 arranged above the main conveyor belt, and the camera rotation following detection machine 31 is vertically adjustable in height, and is configured to complete the bottle mouth defect detection work of bottles to be inspected at different heights.

[0068] Reference Figure 8 The adaptive bottle mouth detection module 3 also includes a rectangular fixed plate 32 arranged above the main conveyor belt, and its lower side is connected to the camera rotation following detection machine 31 through a lifting mechanism 33. The lifting mechanism 33 includes a screw rod 331 arranged vertically and fixed at the lower end to the camera rotation following detection machine 31. A nut 332 spirally connected to the screw rod 331 is also rotatably provided on the fixed plate 32; the lifting mechanism 33 also includes a driving motor 333 drivingly connected to the nut 332. The camera rotation following detection machine 31 includes a main frame 311 connected to the screw rod 331, and a rotating frame 312 slidingly arranged at its lower side along the conveying direction of the main conveyor belt, and a plurality of sampling cameras 313 arranged in an upper and lower staggered manner are arranged in a circular array on the rotating frame 312. The driving motor 333 rotates the nut 332 according to the height of the bottle body to be inspected delivered by the transfer track 13. The screw rod 331 drives the main frame 311 to move up and down to a suitable height under the rotation of the nut 332. After the bottle body to be inspected arrives, the rotating frame 312 moves horizontally with the bottle body, and at the same time drives the sampling camera 313 to rotate and take pictures of the bottle mouth for sampling. The sampling cameras 313 staggered up and down can increase the sampling range of the camera to meet the needs of bottle mouths of different sizes.

[0069] In this embodiment, the rejection module 4 is configured to remove defective bottles from the main conveyor belt, and the bottle collection module 5 is configured to complete the collection of qualified bottles.

[0070] Mixed bottles of different specifications to be inspected are placed in the conveying channel 11. Before the inspection, various mixed bottles are pre-processed by the mixed bottle unscrambling module 1. Under the joint action of the bottle stopping mechanism 12 and the prompting mechanism 14, the bottles to be inspected in different conveying channels 11 enter the transfer track 13 in sequence, and the bottles to be inspected from the conveying channel 11 are moved to the main conveyor belt under the action of the transfer track 13. Subsequently, the bottles to be inspected are inspected for bottlenecks and bottle mouths in sequence. When entering the bottleneck centering inspection module 2, the bottles to be inspected that deviate from the center of the main conveyor belt are first pushed to the middle of the main conveyor belt under the action of the centering mechanism to ensure that the bottles to be inspected can smoothly enter the inspection range of the bottleneck inspection machine 22. At the same time, the bottleneck inspection machine 22 can be raised and lowered according to the height of the bottles to be inspected to achieve the optimal inspection height. After completing the bottleneck defect detection work, the bottle to be inspected begins to perform bottle mouth detection. The camera rotation following detection machine 31 in the adaptive bottle mouth detection module 3 is first adjusted to a suitable height according to the height of the bottle to be inspected. When the bottle reaches the bottle mouth detection position, the camera rotation following detection machine 31 follows the bottle to be inspected to move linearly and synchronously rotates to take pictures and sample. After the detection is completed, the camera rotation following detection machine 31 returns to the initial position to wait for the next bottle. If the bottle fails the inspection, it will be rejected by the rejection module 4, and the qualified bottle will be collected by the bottle collection module 5.

[0071] The entire system can complete bottle defect detection for mixed-production bottles of different specifications, and each module can adapt to changes in bottle specifications and make adjustments. There is no need to add multiple inspection lines, thereby improving bottle inspection efficiency.
