Description

Technical Field

[0001] The present invention relates to the technical field of mask packaging equipment, and particularly relates to a mask machine. Background Art

[0002] As is well known, in the field of beauty care products, masks are one of the commonly used beauty products. During the production process of masks, it is necessary to package the mask products. Currently, in a mask machine, a paging machine is used to horizontally convey packaging bags. After the mask paper is loaded with mask samples, the paging machine uses a wheel shaft to contact and rub against the mask to generate a speed difference, so as to realize the separate conveyance of each mask piece by piece. Since the mask is manually loaded into the bag in the early stage, there may be cases of wrong pieces or missing pieces. Therefore, when the wheel shaft of the paging machine contacts the mask, there will be a phenomenon of being too tight or too loose, resulting in an uncertain speed difference, which causes the mask to run off track or be clamped when separated, thereby reducing the qualification rate of the mask. Summary of the Invention

[0003] The purpose of the present invention is to provide a mask machine, which can improve the accuracy of mask conveyance, ensure the equidistant conveyance of masks, and improve the production efficiency of masks.

[0004] To solve the above technical problems, an embodiment of the present invention provides a mask machine, including:

[0005] A frame;

[0006] A bag suction assembly, including: a driving member, a driving shaft, a synchronous pulley, a flywheel, a pull rod portion, a first suction portion, and a second suction portion; the driving member is arranged on the frame and is used to drive the driving shaft to rotate. The synchronous pulley and the flywheel are respectively arranged at both ends of the driving shaft. The flywheel is eccentrically connected to the pull rod portion, and the pull rod portion is respectively connected to the flywheel and the first suction portion. A negative pressure environment exists inside both the first suction portion and the second suction portion. The pull rod portion is used to drive the first suction portion to move between a first preset position and a second preset position along a preset direction when the flywheel moves. The first suction portion is used to suck mask samples piece by piece when moving to the first preset position. The second suction portion is used to suck the mask samples when the first suction portion drives the mask samples to move to the second preset position.

[0007] A detection device, arranged on the frame and used to detect the thickness of the mask samples;

[0008] A conveyance assembly, arranged on the frame, between the second suction portion and the detection device, and used to jointly convey the mask samples to the detection device with the second suction portion;

[0009] The main control module is electrically connected to the detection device. The main control module is used to determine that the facial mask sample is a qualified product when the detection device detects that the thickness of the facial mask sample is within a preset range; the main control module is further used to determine that the facial mask sample is a defective product when the detection device detects that the thickness of the facial mask sample exceeds the preset range.

[0010] The input assembly line is used to convey the facial mask sample from the previous station to the first preset position.

[0035] To make the objectives, technical solutions and advantages of the present invention clearer, the following will elaborate on various implementation modes of the present invention with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in various implementation modes of the present invention, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solutions claimed in each claim of the present application can still be achieved.

[0036] The implementation mode of the present invention relates to a mask machine. As Figure 1 、 Figure 2As shown in the figure, the facial mask machine includes: a frame 1, a bag suction assembly 2, a conveying assembly 3, a detection device 4, a main control module (not marked in the figure), an input assembly line 5, an output assembly line 6, and a waste kicking device 7. Among them, the bag suction assembly 2, the conveying assembly 3, and the detection device 4 are all arranged on the frame 1, and the detection device 4 and the waste kicking device 7 are both electrically connected to the main control module. The input assembly line 5 is used to continuously convey facial mask samples 10 to the bag suction assembly 2. The bag suction assembly 2 is used to suck the facial mask samples 10. The conveying assembly 3 is used to jointly convey the facial mask samples 10 with the bag suction assembly 2. The detection device 4 is used to detect the thickness of the facial mask samples 10 conveyed by the conveying assembly 3. When the detection device 4 detects that the thickness of the facial mask sample 10 is within the preset range, the main control module determines that the facial mask sample 10 is a qualified product; when the detection device 4 detects that the thickness of the facial mask sample 10 exceeds the preset range, the main control module determines that the facial mask sample 10 is a defective product. After the main control module determines that the facial mask sample 10 is a defective product, the main control module controls the waste kicking device 7 to kick the defective product into the waste bin 79. When the facial mask sample 10 passing through the detection device 4 is a qualified product, the qualified product is conveyed to the next working station through the output assembly line 6. During actual use, the main control module can adopt a single-chip microcomputer or a programmable logic controller PLC.

[0037] Specifically, as Figure 4 shown, the bag suction assembly 2 includes: a driving member 21, a driving shaft 22, a synchronous pulley 23, a flywheel 24, a rod portion 25, a first suction portion 26, and a second suction portion 27. The driving member 21 is used to drive the driving shaft 22 to move. As Figure 5 shown, the driving shaft 22 is connected to the bearing seat through a bearing and fixed on the frame 1 through the bearing seat. The synchronous pulley 23 is fixed on one end of the driving shaft 22 through a tensioning sleeve, and the flywheel 24 is fixed on the other end of the driving shaft 22 through a tensioning sleeve. As Figure 4As shown in the figure, the pull rod part 25 specifically includes: a pull rod 251, a spherical plain bearing spacer 252 arranged on the flywheel 24, spherical plain bearings 253 respectively arranged at both ends of the pull rod 251, and a pull rod connection block 254. Among them, the spherical plain bearing 252 on the side of the pull rod 251 facing the flywheel 24 is eccentrically connected to the flywheel 24 through the spherical plain bearing spacer, and the shape of the flywheel 24 is oval, so that the pull rod 251 can be pushed forward and backward through the moment of inertia of the flywheel 24. The spherical plain bearing 252 at the other end of the pull rod 251 is connected to the connection block 254 through the pull rod connection block 253. On the side of the connection block 254 facing away from the spherical plain bearing 252, two connecting plates 255 are symmetrically arranged, and a suction cup fixing plate 256 is respectively arranged on each connecting plate 255. The first suction part 26 includes: a connection block 261 connected to the pull rod connection block 254, a connecting plate 262 arranged on the connection block 261, a suction cup fixing plate 263 arranged on the connecting plate 262, a plurality of suction cups 264 arranged on the suction cup fixing plate 263, and a suction air component (not marked in the figure) connected to each suction cup 264. And there are two suction cup fixing plates 263, and the same number of suction cups 264 are arranged on each suction cup fixing plate 263, and the suction cups 264 on the two suction cup fixing plates 263 are in one-to-one correspondence; in this embodiment, three suction cups 264 are evenly arranged on each suction cup fixing plate 263, the suction air component is connected to each suction cup 264, and a negative pressure environment is formed by the suction cups 264 under the action of the suction air component. During actual use, the suction air component can adopt a suction fan or a vacuum pump. Further, in this embodiment, a crossbar fixing plate 28 is arranged on the frame 1, two guide rail fixing plates 29 are symmetrically arranged on the crossbar fixing plate 28, and guide rails 210 are symmetrically arranged on each guide rail fixing plate 29. Correspondingly, sliders 220 are respectively arranged at both ends of the connection block 261, and the two sliders 220 on both sides correspond to the two guide rails 210 one by one. When the flywheel 24 rotates to drive the pull rod 251 to move forward and backward, the two sliders 220 slide along the corresponding guide rails 210 respectively, and then drive the suction cup fixing plate 263 and the suction cups 264 fixed on the suction cup fixing plate 263 to slide along the length direction of the guide rails 210. When the suction cups 264 move to the first preset position along the preset direction, they suck the mask sample 10 and drive the mask sample 10 to move to the second preset position. During actual use, the driving member 21 can adopt the form of a motor and a synchronous belt assembly connected to the motor. Specifically, the motor is fixed on the frame 1 and connected to the synchronous belt assembly. The driven wheel of the synchronous belt assembly is coaxially fixed with the main shaft 22. When the motor works, it drives the belt of the synchronous belt assembly to rotate and drives the driven wheel to rotate, and then can drive the main shaft 22 to rotate.

[0038] Further, as Figure 4As shown in the figure, the second suction part 27 includes: a suction box fixing plate 271 connected to the guide rail fixing plate 29, a suction box 272 arranged on the suction box fixing plate 271, and a suction member (not marked in the figure) connected to the suction box 272. A suction air connection port is arranged on the suction box 272, and the suction member sucks air through the suction air connection port, so that negative pressure is generated in the suction box 272. When each suction cup 264 drives the mask sample 10 to move to the second preset position, the mask sample 10 is adsorbed through the suction box 272. In the actual use process, the suction member can adopt a suction fan or a vacuum pump. It is worth mentioning that, in this embodiment, the connecting block 261 and the two suction cup fixing plates 263 are respectively arranged on both sides of the suction box 272, and the suction cup fixing plate 263 is arranged on the suction side of the suction box 272. The suction box fixing plate 271 is provided with a first through hole and a second through hole, and the suction box fixing plate 271 is arranged between the first through hole and the second through hole. The two connecting plates 262 respectively pass through the first through hole and the second through hole to connect the connecting block 261 and the two suction cup fixing plates 263.

[0039] Since the flywheel 24 is a disk-shaped part with a large moment of inertia, during the working process, the synchronous wheel 23 rotates to drive the flywheel 24 to rotate, generating a moment of inertia. The moment of inertia generated by the flywheel 24 drives the pull rod 251 to push back and forth alternately, thereby driving the suction cup 261 to move back and forth. The suction cup 264 can ensure that the mask sample 10 will not fall off in a negative pressure environment. Therefore, the mask samples 10 on the input assembly line 5 can be transported to the suction box 272 one by one. Moreover, since the inertia generated by the flywheel 24 is the same, it can ensure that the movement speed is the same each time, and thus can ensure that the transmission speed of the mask sample 10 is also the same. Therefore, the accuracy of the transmission of the mask sample 10 can be improved, and the mask sample 10 can be transmitted at equal intervals, and the mask sample 10 will not run off or be clamped when separated, thereby improving the production efficiency of the mask sample 10.

[0040] In addition, as Figure 3 , Figure 6 , Figure 7 shown, the conveying assembly 3 includes: two first fixing plates 31, a first driving wheel group 32, several idler wheels 33, a first perforated flat belt 34, several first tensioning wheels 35, a second driving wheel group 36, several second tensioning wheels 37, and a fourth flat belt 38 sleeved outside the second driving wheel group 36 and each second tensioning wheel 37. Specifically, as Figure 6As shown, the two first fixed plates 31 are both curved plates, and are gradually bent upward from the side facing the suction bag assembly 2 to the side facing the detection device 4. The first perforated flat belt 34 is sleeved outside the first driving wheel set 32, each idler wheel 33 and the suction box 272. Since negative pressure is generated inside the suction box 272, the mask sample 10 can be adsorbed onto the transmission flat belt, and the transmission flat belt is transmitted forward under the action of the first driving wheel set 32 and each idler wheel 33. Each first tensioning wheel 35 is used to tension the transmission flat belt, facilitating the forward transmission of the mask sample 10 along the transmission flat belt. As Figure 7 shown, the fourth flat belt 38 is located above the first perforated flat belt 34 and the detection device 4. The mask sample 10 passes between the fourth flat belt 38 and the first perforated flat belt 34, and between the fourth flat belt 38 and the detection device 4. Each second tensioning wheel 37 is used to tension the fourth flat belt 38 and drive the fourth flat belt 38 to rotate. During actual use, both the first driving wheel set 32 and the second driving wheel set 36 can adopt the form of a motor and a synchronous belt assembly connected to the motor. Specifically, the motor is fixed on the frame 1 and connected to the synchronous belt assembly. The first perforated flat belt 34 is sleeved outside the driven wheel 422 of the synchronous belt assembly and each idler wheel 33. When the motor works, it drives the belt of the synchronous belt assembly to rotate, and drives the driven wheel 422 to rotate, thereby driving each idler wheel 33 and each second tensioning wheel 37 to rotate synchronously.

[0041] Further, as Figure 7As shown in the figure, the detection device 4 specifically includes: a first suction box 41, a conveyor belt assembly 42, a first support plate 43 and a second support plate 44, a detection roller set 45, a rocker arm assembly 46, a sensor bracket 47 and a sensor 48. Specifically, the conveyor belt assembly 42 includes a driving wheel 421, four driven wheels 422 and a second perforated flat belt 423. The second perforated flat belt 423 is sleeved on the outside of the driving wheel 421, the four driven wheels 422 and the first suction box 41. In addition, in this embodiment, the detection device further includes a tensioning wheel, and the second perforated flat belt 423 can be tensioned by the tensioning wheel to facilitate the transmission of the mask sample 10. The first suction box 41 is externally connected to a suction component, and a negative pressure is formed in the first suction box 41 through the suction component. The mask sample 10 is conveyed forward between the fourth flat belt 38 and the second perforated flat belt 423. Under the action of the suction negative pressure of the first suction box 41, it is ensured that the mask sample 10 is adsorbed on the second perforated flat belt 423 and is conveyed forward along with the movement of the second perforated flat belt 423. The first support plate 43 and the second support plate 44 are oppositely arranged on both sides of the first suction box 41 and are connected by a detection cross brace, and the length direction of the detection cross brace is perpendicular to the transmission direction of the second perforated flat belt 423. The rocker arm assembly 46 specifically includes: a first rocker arm 461, a second rocker arm 462, and a connecting arm 463 connecting the first rocker arm 461 and the second rocker arm 462. Both ends of the connecting arm 463 are connected to the first support plate 43 and the second support plate 44 respectively. In addition, the detection roller set 45 and the connecting arm 463 are rotatably arranged between the first rocker arm 461 and the second rocker arm 462, and the detection roller set 45 is located between the detection cross brace and the conveyor flat belt. A detection end is provided on the first rocker arm 461. The first rocker arm 461, the second rocker arm 462, the connecting arm 463 and the detection roller set 45 together form a lever structure. The connecting arm 463 serves as the fulcrum of the lever structure, and the distance between the detection end and the connecting arm 463 is greater than the distance between the connecting arm 463 and the detection roller set 45. In addition, a sensor bracket 47 is provided on the frame 1, and a sensor 48 is provided on the sensor bracket 47. The sensor 48 is electrically connected to the main control module, and the detection component of the sensor 48 is directly opposite to the detection end of the first rocker arm 461. Specifically, when the mask sample 10 moves to the detection roller set 45 along with the second perforated flat belt 423, the position height of the detection roller set 45 changes, and the detection end on the first rocker arm 461 moves up and down synchronously. Moreover, since the distance between the detection end and the connecting arm 463 is greater than the distance between the connecting arm 463 and the detection roller set 45, according to the characteristics of the lever structure, the distance that the detection end moves up and down is greater than the distance that the detection roller set 45 moves up and down. Therefore, the detection accuracy of the sensor 48 can be improved, and thus it can more accurately measure whether the mask sample 10 is qualified, effectively improving the qualification rate of the mask sample 10.During actual use, the sensor 48 can be set on only one side of the first rocker arm 461 for detection, or sensors 48 can be set on both sides of the first rocker arm 461 and the second rocker arm 462 for simultaneous detection. In addition, in this embodiment, a proximity sensor is used for sensing. Specifically, according to the height difference generated by the detection roller set 45 when the mask sample 10 passes by, the height difference generated at the detection end of the first rocker arm 461 is calculated, and a proximity sensor 48 is respectively provided at the lowest position and the highest position that the detection end will reach. When the mask sample 10 passing through the detection roller set 45 is a qualified product, the first rocker arm 461 moves up and down within a preset range and will not be detected by any of the proximity sensors 48, and the mask sample 10 is conveyed to the output assembly line 6; when the mask sample 10 passing through the detection roller set 45 is a defective product, the first rocker arm 461 is detected by the proximity sensor 48 at the highest position or the lowest position, and the main control module determines that the mask sample 10 passing through the detection roller set 45 at present is a defective product, and controls the reject device 7 to kick the mask sample 10 into the waste bin, so as to realize the detection of whether the mask sample 10 is qualified. During actual use, other forms of sensors can also be used for the sensor 48.

[0042] It should be noted that, such as Figure 8As shown in the figure, the input pipeline 5 specifically includes: a first bracket 51, a first turbine reducer 52, a first synchronous belt assembly 53, a first side baffle 54, a second side baffle 55, and a support block 56. Specifically, the first turbine reducer 52, the first synchronous belt assembly 53, and the first side baffle 54 and the second side baffle 55 are all arranged on the first bracket 51. Among them, the first synchronous belt assembly 53 is used to convey the mask sample 10, and specifically includes: a first driving wheel, a first driven wheel, a second driven wheel, and a first flat belt. The first driven wheel is arranged opposite to the first driving wheel, the second driven wheel and the first driven wheel are located in the same plane and arranged opposite to each other, and the first flat belt is sleeved outside the first driving wheel, the first driven wheel, and the second driven wheel. The first driving wheel is connected to the first turbine reducer 52. When the first turbine reducer 52 works, the first driving wheel rotates, and the first flat belt moves forward along with the first driving wheel, the first driven wheel, and the second driven wheel. Further, the first side baffle 54 and the second side baffle 55 are respectively located on both sides of the first flat belt. The length direction of the first baffle and the second baffle is the conveying direction of the first flat belt, and the distance between the first side baffle 54 and the second side baffle 55 is the same as the width of the mask sample 10. Therefore, the mask sample 10 can be conveyed vertically forward. In addition, in this embodiment, the support block 56 is arranged on the first flat belt of the first synchronous belt assembly 53, and the mask sample 10 placed on the first flat belt is supported by the support block 56 to ensure that the mask sample 10 placed on the first flat belt is always in a vertical state, which further facilitates the suction bag assembly 2 to suck the mask sample 10. During actual use, multiple support blocks 56 can be arranged at equal intervals on the first flat belt, or they can also be placed at appropriate positions on the first flat belt by the operator according to the actual situation.

[0043] In addition, in this embodiment, as Figure 9 shown, the output pipeline 6 includes: a second bracket 61, a second synchronous belt assembly 62, and a stacking and pushing-out assembly 63. Among them, the second synchronous belt assembly 62 and the stacking and pushing-out assembly 63 are both arranged on the second bracket 61. The stacking and pushing-out assembly 63 is arranged on the side of the second bracket 61 close to the waste kicking device 7 and is used to push the qualified products onto the second synchronous belt assembly 62, and the second synchronous belt assembly 62 is used to convey the qualified products to the next station. Specifically, as Figure 10As shown in the figure, the laminated sheet pushing component 63 includes: a first cylinder 631, a second fixed plate 632, a push plate 633, a trough tray 634, a screw rod fixing seat 635, an adjusting screw rod 636, a handwheel 637 and a third bracket 638. Among them, the first cylinder 631, the second fixed plate 632 and the screw rod fixing seat 635 are all arranged on the frame 1, the adjusting screw rod 636 and the handwheel 637 are both arranged on the screw rod fixing seat 635, and the screw rod fixing seat 635 is connected to the trough tray 634 through the third bracket 638 to improve the stability of the trough tray 634. The first cylinder 631 has a first telescopic rod. The push plate 633 is arranged on the second fixed plate 632, and the first cylinder 631 and the trough tray 634 are respectively located on both sides of the push plate 633. Specifically, the trough tray 634 includes two oppositely arranged support plates, and a placement area for accommodating the facial mask samples 10 is formed between the two support plates. The adjusting screw rod 636 is connected to any one of the support plates of the trough tray 634, and the handwheel 637 is connected to the adjusting screw rod 636. When the handwheel 637 rotates, it drives the adjusting screw rod 636 to move. The movement of the adjusting screw rod 636 drives the support plate connected to the adjusting screw rod 636 to move, and thus the distance between the two support plates can be adjusted, so that facial mask samples 10 of different sizes can be transported. During actual use, the facial mask samples 10 are sequentially transported to the placement area of the trough tray 634. When the number of facial mask samples 10 in the placement area reaches the preset number, the first cylinder 631 works to drive the first telescopic rod to push forward, and the facial mask samples 10 in the placement area are pushed onto the second synchronous belt assembly 62. Therefore, a group of facial mask samples 10 with the preset number can be pushed forward as a group, which is convenient for subsequent packaging.

[0044] In addition, as Figure 9 shown in the figure, the second synchronous belt assembly 62 includes: a second turbine reducer 621, a second driving wheel 622, a third driven wheel 623 oppositely arranged relative to the second driving wheel, and a second flat belt 624 sleeved outside the second driving wheel 622 and the third driven wheel 623. The second turbine reducer 621 works to drive the second driving wheel 622 to move, and then drives the second flat belt 624 to transport forward. Therefore, the group of facial mask samples 10 pushed out by the laminated sheet pushing mechanism can be transported forward to the next working station.

[0045] Furthermore, as Figure 11As shown, the waste kicking device 7 includes: a third driving wheel 71, a first adjusting wheel 72 and a second adjusting wheel 73 arranged opposite to each other, a second suction box 74, a third perforated flat belt 75, a second cylinder 76, a first bearing seat, a joint bearing, a connecting shaft 77, a first bearing and two sheeting plates 78. Among them, the second suction box 74 is arranged between the first adjusting wheel 72 and the second adjusting wheel 73, the second cylinder 76 and the first bearing seat are both arranged on the frame 1, the third perforated flat belt 75 is sleeved on the third driving wheel 71, the first adjusting wheel 72, the second adjusting wheel 73 and the outer side of the second suction box 74, and the third perforated flat belt 75 is used to rotate around the third driving wheel 71, the first adjusting wheel 72 and the second adjusting wheel 73 when the third driving wheel 71 moves, and the third perforated flat belt 75 is also used to drive the mask sample 10 to move forward when moving. Specifically, the second cylinder 76 is electrically connected to the main control module and has a second telescopic rod. The joint bearings are respectively connected to the second telescopic rod and the first bearing seat. The connecting shaft 77 is arranged above the second suction box 74. The first bearing is used to connect the first bearing seat and the connecting shaft 77. Two sheet-beating plates 78 are both arranged on the connecting shaft 77 and are respectively located on both sides of the second suction box 74. Each sheet-beating plate 78 is used to rotate around the axial direction of the connecting shaft 77 when the second cylinder 76 drives the second telescopic rod to perform telescopic movement. Further, when the mask sample 10 passing through the waste kicking device 7 is a qualified product, , the two beating plates 78 are parallel to the second suction box 74, and the mask sample 10 can pass through the kicking device 7 smoothly; when the mask sample 10 passing through the kicking device 7 is a defective product, the main control module controls the movement of the second cylinder 76, and the second cylinder 76 moves, driving the two beating plates 78 to rotate toward one side of the waste box through the joint bearing, the first bearing and the connecting shaft 77, and moving the defective products to the side away from the second suction box 74, so that the defective products are separated from the second suction box 74, and the defective products are separated from the second suction box 74, and lose the negative pressure suction of the second suction box 74, and fall into the waste box under the action of gravity. In actual use, the kicking device 7 can also include a plurality of tensioning wheels arranged on the third perforated flat belt 75, and the third perforated flat belt 75 can be tightened by each tensioning wheel.

[0046] Furthermore, in this embodiment, if Figure 11 As shown, the facial mask machine also includes: a fixed adjustment plate 8 and two guide strips 9. The fixed adjustment plate 8 is arranged above the second air suction box 74, and the two guide strips 9 are detachably arranged on the fixed adjustment plate 8, and each guide strip 9 is located above the push plate 633 of the laminate push-out assembly 63. The facial mask sample 10 is located between the two guide strips 9. By adjusting the position of the guide strips 9 on the fixed adjustment plate 8, the position of the facial mask sample 10 falling into the trough tray 634 can be adjusted. In actual use, an adjustment hole can be opened on the fixed adjustment plate 8, and the two guide strips 9 are respectively locked and fixed with the corresponding adjustment holes by bolts.

[0047] It is not difficult to find from the above that the mask sample 10 at the previous station is conveyed to the bag suction assembly 2 through the input assembly line 5. The bag suction assembly 2 sucks the mask samples 10 one by one and conveys them to the detection device 4 through the conveying assembly 3. The detection device 4 detects the thickness of the passing mask sample 10. When the detected mask thickness is lower or higher than the set normal thickness, the main control module determines that the passing mask sample 10 is a defective product. After the main control module determines that the passing mask sample 10 is a defective product, it controls the waste kicking device 7 to kick the defective product into the waste bin 79. When the mask thickness detected by the detection device 4 is the preset thickness, the main control module determines that the passing mask sample 10 is a qualified product. After the main control module determines that the passing mask sample 10 is a qualified product, the mask sample 10 continues to be conveyed forward to the output assembly line 6, and the qualified mask sample 10 is conveyed to the next station through the output assembly line 6. Therefore, the bag suction assembly 2 of this mask machine does not need to consider the situation of wrong or missing pieces in mask bagging. It can directly convey the mask samples 10 one by one backward from the input assembly line 5, and then detect the thickness of the mask samples 10 through the detection device 4 to determine whether the passing mask samples 10 are qualified products. When the detected mask sample 10 is a qualified product, it is directly conveyed forward to the output assembly line 6 and conveyed to the next station through the output assembly line 6. When the detected mask sample 10 is a defective product, the defective product is kicked into the waste bin 79 through the waste kicking device 7. Therefore, the mask production efficiency can be improved and the qualification rate of mask finished products can be increased.
