Description

Technical Field

[0001] The invention belongs to the technical field of visual acquisition equipment, and in particular relates to a full-automatic sheath detection machine. Background Art

[0002] In the medical market, the sheaths used mainly for the protection of needle tube products are widely used. There are various types of sheaths, and their appearance, shape, size, etc. are very different. They are generally slender and round. According to quality requirements, defective sheaths that are broken, damaged, or have impurities on the surface during the production process need to be selected. At present, unqualified defective sheaths are mainly selected manually, which not only has high labor costs, but also makes it difficult to fully grasp the appearance, shape and size of the sheath, which is easy to cause misdetection and missed detection, affecting the qualified rate of the sheath.

[0003] With the development of visual acquisition technology, there are already fully automatic visual acquisition equipment for medical bottle caps, plugs, etc. in the prior art. However, the shapes of these bottle caps, plugs, etc. being inspected are short and thick, which can be placed stably on the inspection plane and are heavy. As the machine runs, the inspected objects will not move or overturn. In addition, the shapes of bottle caps, plugs, etc. are also very clear, and each surface to be inspected is easy to confirm and inspect. However, the sheath is slender in shape and light in weight. In the existing inspection equipment, it is easy to roll and shift, resulting in the inability to confirm which part of the sheath the captured image belongs to, so that the inspection cannot be completed.

[0012] The kicking mechanism is used to remove the unqualified products in the tested sheath from the testing machine.

[0013] The material sorting mechanism includes a front air suction and blowing device, an air blowing removal device and a rear air suction and blowing device. The front air suction and blowing device, the air blowing removal device and the rear air suction and blowing device are sequentially arranged in front of the horizontal sorting and detection working section of the conveyor belt. The front of the horizontal sorting and detection working section is the part that the conveyor belt passes through first. The front air suction and blowing device includes a front air suction groove pipe and a front air blowing pipe. The front air suction groove pipe has an interface connected to the suction power source and a gap connected to the inner cavity of the front air suction groove pipe. The gap is aligned with the edge of the conveyor belt, and the sheath in the inverted triangle notch of the suction conveyor belt is aligned with the edge of the conveyor belt.

The lower edge of the U-shaped feeding structure is located above the outer surface of the conveyor belt of the inclined sorting working section, and there is a gap between the outer surface of the conveyor belt, and the gap is smaller than the diameter of the sleeve. The upper end opening of the U-shaped feeding structure is consistent with the movement direction of the conveyor belt. The brush is rotatably installed between the two side baffles through a bearing.

The structures of the second waste kicking device and the third waste kicking device are consistent with the structure of the first waste kicking device.

[0018] The beneficial effects of the present invention are as follows: 1) the fully automatic sheath detection machine of the present invention adopts a conveyor belt with inverted triangle slots, each slot can be corresponding to a sheath, and the sheaths are sorted, sorted and arranged neatly by limiting and blowing with a brush; 2) due to the limiting effect of the inverted triangle slots, the sheath will not roll in the slots, and the two end faces of the sheath located in the slots can be accurately detected; 3) two sets of belts with suction pinholes connected in series are adopted, and the sheath is fixed on the belt by suction through the suction pinholes, and the circumferential outer surface of the sheath is comprehensively photographed and detected; 4) the belt with suction pinholes is arranged perpendicular to the conveyor belt. If it is arranged in a linear direction, an adsorption transmission method is adopted, and a large area is required for adsorption, and the suction force is relatively scattered, and the sheath cannot be sucked and transmitted instantly. 90° right-angle adsorption transmission requires a smaller surface for adsorption, which makes it easy to create a suction gap with concentrated suction force. The instantaneous suction force is large, the adsorption is firm, and it is not easy to fall off; 5) The conveyor belt and the belt are driven by a stepper motor with an encoder, which can accurately locate the position of each sleeve; 6) A single-tube air blow pipe is used for kicking and blowing away waste to avoid affecting other sleeves when kicking away waste.

DETAILED DESCRIPTION

[0031] The specific technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0032] As attached Figure 1 As shown, a fully automatic sheath inspection machine of the present invention comprises a feeding mechanism 2, a conveyor belt mechanism 3, a material sorting mechanism, an upper suction belt mechanism 5, a lower suction belt mechanism 6, a waste kicking mechanism and a visual collection device.

[0033] As attached Figure 2 As shown, the conveyor belt mechanism includes a conveyor belt 31 that can circulate, a conveyor belt driving wheel, and a first stepper motor with an encoder for driving the conveyor belt driving wheel to rotate. The outer surface of the conveyor belt 31 has continuously and evenly distributed inverted triangular notches, and the direction of the inverted triangular notches is perpendicular to the movement direction of the conveyor belt 31. Only one sheath 0 can be placed in the inverted triangular notch, and the height of the two side walls of the inverted triangular notch is greater than the diameter of the sheath 0. Figure 3 As shown, the conveyor belt 31 has an inclined sorting working section and a horizontal sorting and testing working section. When the conveyor belt 31 is running, it first passes through the inclined sorting working section and then passes through the horizontal sorting and testing working section.

[0034] As attached Figure 2-4 As shown, the material sorting mechanism is used to neatly arrange the sleeves 0 in the inverted triangle slots of the conveyor belt 31, with only one sleeve 0 placed in each inverted triangle slot, and one end of each sleeve 0 is aligned with the same edge of the conveyor belt 31 of the conveyor belt mechanism.

[0035] The material sorting mechanism includes a baffle assembly 41, a brush 42, a brush motor, a front air suction and blowing device 43, an air blowing removal device 44 and a rear air suction and blowing device 45. The baffle assembly 41 includes two side baffles and a lower baffle. The two side baffles and the lower baffle form a U-shaped feeding structure. The lower edge of the U-shaped feeding structure is located on the outer surface of the conveyor belt 31 of the inclined sorting work section, and there is a gap between the outer surface of the conveyor belt 31. The gap is smaller than the diameter of the sleeve 0. The upper end opening of the U-shaped feeding structure is consistent with the movement direction of the conveyor belt 31. The brush 42 is rotatably installed between the two side baffles through a bearing. The brush 42 can rotate under the drive of the brush motor, so that the bristles of the brush 42 brush over the conveyor belt 31 in the direction opposite to the movement direction of the conveyor belt 31, and sweep the sleeve 0 above the inverted triangle slot to the opposite direction of the movement of the conveyor belt 31.

[0036] The distance between the brush 42 and the inverted triangle notch should be carefully adjusted during installation, so that the brush 42 is close to the surface of the belt teeth, and the brush surface and the belt surface cannot be skewed, so that the sheath 0 accumulated on the belt teeth can be blocked and cleaned by the brush 42, and only the sheath 0 falling into the inverted triangle notch can be conveyed to the horizontal sorting and detection working section. The brush 42 rotates counterclockwise at high speed, and through rotational friction, the sheath 0 accumulated on the brush 42 and not falling into the inverted triangle notch is thrown away, and the accumulated sheath 0 falls freely on the conveyor belt 31 again after being thrown away. The faster the brush 42 rotates, the more efficient the sheath 0 can be thrown away, and the accumulated sheath 0 should also be prevented from falling out. The brush 42 cannot rotate clockwise, because when the brush 42 rotates clockwise, the accumulated sheath 0 will be squeezed into the inverted triangle notch, thereby increasing the sheath 0 accumulated in the inverted triangle notch, directly affecting the material sorting effect. There can be multiple brushes 42, and the spacing between the multiple brushes 42 is consistent, and the spacing between the feeding channels is consistent, so that the overall feeding speed of the sheath 0 can be consistent. The brush 42 is made of flexible material, and when it rotates at high speed, it will not cause any damage to the sheath 0. The conveyor belt 31 of the inclined sorting work section is set to a certain slope. When the number of sheaths 0 close to the brush 42 increases, the subsequent sheaths 0 will automatically fall to the rear due to the slope, so that the accumulated sheaths 0 will not be too concentrated.

[0037] The front air suction and blowing device 43, the blowing and removing device 44 and the rear air suction and blowing device 45 are sequentially arranged at the front part of the horizontal sorting and detecting working section of the conveyor belt 31. The front part of the horizontal sorting and detecting working section is the part that the conveyor belt 31 passes through first. When the conveyor belt 31 is running, it first passes through the front air suction and blowing device 43. The front air suction and blowing device 43 is used to preliminarily align the sleeve 0 on one edge of the conveyor belt 31. The blowing and removing device 44 blows the sleeve 0 that is higher than the inverted triangle notch of the conveyor belt 31 away from the conveyor belt 31. The rear air suction and blowing device 45 is used to align the sleeve 0 on this edge of the conveyor belt 31 again.

[0038] The front air suction and blowing device 43 comprises a front air suction slot pipe 431 and a front air blowing pipe 432, the front air suction slot pipe 431 having an interface connected to a suction power source and a gap connected to an inner cavity of the front air suction slot pipe 431, the gap being aligned with the edge of the conveyor belt 31, attracting the sheath 0 in the inverted triangular notch of the conveyor belt 31 to be aligned with the edge of the conveyor belt 31, the air outlet size of the front air blowing pipe 432 corresponding to the cross-sectional size of the inverted triangular notch of the conveyor belt 31, and being used for blowing the sheath 0 in the inverted triangular notch of the conveyor belt 31 to be aligned with the edge of the conveyor belt 31 at the front air suction slot pipe 431 The air blowing removal device 44 includes an air blowing removal pipe 441, the air outlet size of the air blowing removal pipe 441 corresponds to the cross-sectional size of the inverted triangle notch of the conveyor belt 31, the air outlet of the air blowing removal pipe 441 is slightly higher than the upper edge of the side wall of the inverted triangle notch of the conveyor belt 31, and is used to blow the excess sheath 0 superimposed in the inverted triangle notch away from the conveyor belt 31, the rear air suction blowing device 45 includes a rear air suction groove pipe 451 and a rear air blowing pipe 452, the structure of the rear air suction groove pipe 451 and the rear air blowing pipe 452 is the same as the structure of the front air suction groove pipe 431 and the front air blowing pipe 432.

[0039] The feeding mechanism 2 includes a feeding hopper, a material box, a vibrating plate and a feeding port. The feeding hopper sends the poured sheath 0 to be tested to the material box, where it is gathered and then input into the vibrating plate. The vibrating plate then evenly drops the sheath 0 into the U-shaped feeding structure formed by the baffle assembly 41 of the material sorting mechanism through the feeding port.

When the conveyor belt 31 passes through the upper suction pinhole belt 51, the suction generated by the gap of the upper suction slot tube 52 passes through the through hole of the upper suction pinhole belt 51, and adsorbs the sheath 0 on the upper suction pinhole belt 51.

[0041] The distance between the conveyor belt 31 and the upper suction pinhole belt 51 needs to be adjusted according to the size of the jacket 0 to achieve the best suction effect. The upper suction slot 52 needs to be close to the pinhole belt, and the suction gap of the upper suction slot 52 needs to face the through hole of the belt. The distance between the conveyor belt 31 and the belt should be adjusted to between 0.5mm and 1mm to ensure that the jacket 0 can pass smoothly between the belts without being stuck and can be sucked away smoothly by the suction.

[0042] As attached Figure 8As shown, the lower air suction belt mechanism 6 includes a lower air suction pinhole belt 61 capable of circulating, a lower air suction groove pipe 62, a lower air suction pinhole belt driving wheel and a third stepping motor with an encoder for driving the lower air suction pinhole belt driving wheel to rotate, the lower air suction pinhole belt 61 has through holes evenly distributed along the length direction of the belt in the middle of the belt, the lower air suction pinhole belt 61 has a horizontal lower air suction working section, the outer surface of the belt at the horizontal lower air suction working section points away from the ground, and the movement direction of the belt at this location is parallel to the movement direction of the upper air suction pinhole belt 51 at the horizontal upper air suction working section, the lower air suction groove pipe 62 has an interface connected to the air suction power source and a gap connected to the inner cavity of the lower air suction groove pipe 62, the lower air suction working section at the lower air suction pinhole belt 61 has a lower air suction pinhole belt 61, and ...

[0043] like Figure 8-10 As shown, the visual acquisition device is used to capture images of both ends of the sleeve 0 and its outer surface in the length direction. The visual acquisition device includes a first camera assembly 81, a second camera assembly 82, a third camera assembly 83, and a fourth camera assembly 84. The first camera assembly 81 is installed on both sides of the conveyor belt 31 of the horizontal sorting and detection work section and is located between the upper suction belt mechanism 5 and the rear suction and blowing device 45, and is used to capture images of both ends of the sleeve 0.

[0044] The kicking mechanism is used to remove the unqualified products in the tested sheath 0 from the detection machine. The kicking mechanism includes a first kicking device 71, a second kicking device 72 and a third kicking device 73. The first kicking device 71 is installed on both sides of the conveyor belt 31 of the horizontal sorting and detection work section and is located between the first camera assembly 81 and the upper suction belt mechanism 5, and is used to remove the unqualified products detected by the first camera assembly 81. The first kicking device 71 includes an air-blowing kicking pipe and a waste box. The air outlet size of the air-blowing kicking pipe corresponds to the cross-sectional size of the inverted triangle notch of the conveyor belt 31. It is used to blow the unqualified products in the inverted triangle groove away from the conveyor belt 31 and into the waste box. The second kicking device 72 is installed at the rear part of the horizontal upper suction working section and is located on both sides of the upper suction pinhole belt 51. It is used to remove the unqualified products detected by the second camera assembly 82 and the third camera assembly 83. The third kicking device 73 is installed at the rear part of the horizontal lower suction working section and is located on both sides of the lower suction pinhole belt 61.

[0045] The air suction gaps of the front air suction groove pipe 431, the rear air suction groove pipe 451, the upper air suction groove pipe 52 and the lower air suction groove pipe 62 are as shown in the attached Fig.11 shown.

[0046] The working process of the embodiment of the fully automatic sheath detection machine of the present invention is as follows:

[0047] 1) Pour the sheath 0 into the feeding mechanism 2;

[0048] 2) The sheath 0 is arranged in order through the material sorting mechanism to ensure that there is only one sheath in each inverted triangle slot;

[0049] 3) After the sheaths 0 are neatly arranged, under the control of the industrial computer, the optical fiber sensor locates the position of each inverted triangle notch with the sheath 0 inside;

[0050] 4) The sheath passes through the first camera assembly 81 station, and the camera captures images of both ends of the sheath 0;

[0051] 5) The system judges the image captured by the first camera assembly 81. If it is an unqualified sheath 0, the solenoid valve of the first kicking device 71 works, and its air-blowing kicking pipe kicks off the unqualified sheath by air blowing;
