Certain terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present invention.

[0048] As attached Figure 1 ~Attached Figure 2 As shown, this embodiment provides a sheath 5 detection device, including a conveying unit 1 and a detection unit 2, the conveying unit 1 includes a carrying device 11 and a positioning device, the carrying device 11 has a conveying route 13, a plurality of carrying structures are arranged along the conveying route 13, each carrying structure carries a sheath 5, and the sheath 5 is stabilized in the carrying structure under the action of the positioning device; the detection unit 2 includes a plurality of detection devices arranged along the conveying route 13, each of the detection devices includes a detection camera, a detection area can be formed according to the detection range of each of the detection cameras, and the detection area covers the conveying route 13, the plurality of detection devices include a bottom detection device 21, a top detection device 22 and an outer wall detection device 23, wherein the outer wall detection device 23 includes at least three detection cameras, and the at least three detection cameras are evenly distributed along the detection area of ​​the outer wall detection device 23.

[0049] See also Figure 3 , Figure 3The structure diagram of the sheath 5 in this embodiment is shown as follows. Figure 3 It can be seen that the sheath 5 is a long and thin rod-shaped structure. Therefore, during the movement detection of the sheath 5, the movement stability of the sheath 5 needs to be considered. In this embodiment, the sheath 5 can maintain a stable state in the bearing structure under the action of the positioning device, and pass through multiple detection devices in a stable state. The multiple detection devices detect the structures of different parts of the sheath 5, and obtain good sheaths 5 and defective sheaths 5 after detection. Not only is the detection process simple and efficient, but the fully automatic detection process removes human interference, which can improve the reliability and accuracy of the sheath 5 detection.

[0050] In this embodiment, the detection device also includes an R angle detection device 24, which is used to detect the R angle of the top side of the sheath 5, and includes at least two detection cameras, and at least two detection cameras are evenly distributed along the detection area.

[0051] Optionally, the above-mentioned carrying device 11 may be a linear carrying device, and accordingly, the conveying route 13 is a linear conveying route 13. Considering the integration of the sheath 5 detection device to avoid the sheath 5 detection device occupying too much space, in this embodiment, the carrying device 11 includes a first detection tray 111 and a second detection tray 112, the first detection tray 111 has a plurality of first bearing structures, the second detection tray 112 has a plurality of second bearing structures, and the first bearing structures and the second bearing structures are continuously and evenly distributed along the conveying route 13; see Figure 5 There is a handover position 115 on the conveying route 13, and the handover position 115 is jointly defined by the first supporting structure and the second supporting structure relative to each other on the two inspection disks, that is, when each first supporting structure passes through the handover position 115, there is a corresponding second supporting structure passing through the handover position 115 at the same time, so as to realize the transfer of the sheath 5 carried by the first supporting structure at the handover position 115 to the second handover position 115.

[0052] To prevent the sheath from tipping over when the sheath is transferred at the transfer position 115, in the present embodiment, the first inspection tray 111 and the second inspection tray 112 are staggered in height, that is, the disk height of the first inspection tray 111 is higher or lower than the disk height of the second inspection tray 112. If the disk heights of the first inspection tray 111 and the second inspection tray 112 are the same, the sheath needs to be transferred at the transfer position 115 defined by the first supporting structure and the second supporting structure of the same height. Due to errors in the actual installation and processing process and the sheath itself having a slender rod-like structure, it is easy to tip over when the materials are transferred.

[0053] Specifically, the direction of rotation of the first detection disk 111 and the second turntable can be determined according to the setting position of each detection device, including the first detection disk 111 and the second detection disk 112 have the same or opposite rotation direction. If the rotation direction is the same, when the sheath 5 is transferred from the first bearing structure to the second bearing structure at the handover position 115, the movement direction of the sheath 5 needs to change significantly, which will increase the difficulty of the positioning device to stabilize the sheath 5 on the second bearing structure. Therefore, in a preferred embodiment, the first detection disk 111 and the second detection disk 112 have opposite rotation directions and equal linear speeds. For example, in this embodiment, the first detection disk 111 rotates counterclockwise, and the second detection disk 112 rotates clockwise.

[0054] Since the sheath 5 is a light and slender rod structure, it is difficult for the sheath 5 to remain stable by itself without the action of external force, which makes it difficult for multiple detection devices to detect the sheath 5. Therefore, a positioning device is required to provide a force to stabilize the sheath 5 during the detection process; in addition, when detecting the sheath 5, it is essential to detect the bottom of the sheath 5. Therefore, it is also necessary to consider how to make the sheath 5 fly through the detection device that detects the bottom of the sheath 5.

[0055] In an optional embodiment, when the sheath 5 is located on the conveying route 13 on the first inspection tray 111, the positioning device absorbs the top of the sheath 5 and provides suction for the sheath 5. At this time, the bottom of the sheath 5 is suspended in the air and the outer wall is unobstructed. Optionally, a bottom detection device 21 and an outer wall detection device 23 are set on the conveying route 13 on the first inspection tray 111; when the sheath 5 is located on the conveying route 13 on the second inspection tray 112, the positioning device absorbs the bottom of the sheath 5 and provides suction for the sheath 5. At this time, the top and outer wall of the sheath 5 are unobstructed. Optionally, a top detection device 22 and an outer wall detection device 23 are set on the conveying route 13 on the second inspection tray 112.

[0056] In another optional embodiment, when the sheath 5 is located on the conveying route 13 on the first inspection tray 111, the positioning device covers the side walls of the sheath 5 and provides pressure for the sheath 5 to stabilize the sheath 5 in the first bearing structure. At this time, the bottom and top of the sheath 5 are unobstructed. Optionally, a top detection device 22 and a bottom detection device 21 are set on the conveying route 13 on the first inspection tray 111; when the sheath 5 is located on the conveying route 13 on the second inspection tray 112, the positioning device adsorbs the bottom or top of the sheath 5 and provides suction for the sheath 5. At this time, the outer wall of the sheath 5 is unobstructed. Optionally, an outer wall detection device 23 is set on the conveying route 13 on the second inspection tray 112.

[0057] In this embodiment, Figure 5It can be seen that the first inspection disk 111 is a toothed disk, and the first bearing structure is the tooth socket 113 of the toothed disk. A bottom detection device 21 and a top detection device 22 are arranged on the conveying route 13 of the first inspection disk 111. The positioning device provides pressure for the sleeve 5 in the tooth socket 113, so that the sleeve 5 is stable in the tooth socket 113, and ensures that the bottom and top of the sleeve 5 are not blocked when passing through the bottom detection device 21 and the top detection device 22; the second inspection disk 112 is a circular disk, and the second bearing structure is a plurality of adsorption holes 114 distributed at the outer edge of the circular disk. An outer wall detection device 23 is arranged on the conveying route 13 of the second inspection disk 112, and the positioning device provides suction for the sleeve 5 through the plurality of adsorption holes 114. When the sleeve 5 passes through the outer wall detection device 23, the outer wall is not blocked and remains stable.

[0058] Optionally, the positioning device providing pressure includes a round belt mechanism 121, such as Figure 6 As shown, the round belt mechanism 121 includes a bracket 1211, a guide bar 1213 and a round belt 1212. The shape of the bracket 1211 matches the shape of the conveying route 13, and there is a gap between the bracket 1211 and the carrying device 11. The round belt 1212 is arranged in close contact with the bracket 1211, and a guide bar 1213 is arranged between the round belt 1212 and the bracket 1211. The round belt 1212 contacts and presses the sheath 5 to maintain the stability of the sheath 5. After being transported over a long distance, the round belt 1212 may shift. The guide bar 1213 arranged on the back of the round belt 1212 can increase the friction between the round belt 1212 and the guide bar 1213 to prevent the position of the round belt 1212 from shifting.

[0059] Optionally, the positioning device providing suction force includes a negative pressure adsorption mechanism 122, and the negative pressure adsorption mechanism 122 includes a fan and an air cavity, such as Figure 7 As shown, the negative pressure adsorption mechanism 122 includes an adsorption end 1221 and an exhaust end 1222. The adsorption end 1221 is attached to the back of the conveying route 13 of the bearing device 11 to form a cavity. The cavity exchanges gas with the outside world only through the bearing structure. In this embodiment, the cavity exchanges gas with the outside world through the multiple adsorption holes 114 distributed on the edge of the second detection disk 112 to provide suction to the sheath 5 through the adsorption holes 114. The exhaust end of the air cavity is connected to the fan to discharge the gas in the air cavity into the fan. When the fan is running, vacuum suction is formed in the cavity to adsorb the sheath 5 through the multiple adsorption holes 114. It can be understood that the structure of the air cavity should be adapted to the line shape of the conveying route 13 where the bearing structure is located. In this embodiment, the shape of the adsorption end 1221 of the air cavity attached to the back of the second detection disk 112 is semicircular.

[0060] It can be understood that the positioning device can be set as two relatively independent states with the bearing structure as shown in the embodiment, or it can be directly formed in the bearing structure to form an integrated design.

[0061] In this embodiment, when the sheath 5 moves to the toothed disk to hand over materials, material jamming may occur, including the sheath 5 tipping over or tilting and getting stuck in the first detection disk 111 and continuing to move with the first detection disk 111, thereby affecting the detection result of the sheath 5. In severe cases, important components of the sheath 5 detection equipment may be damaged.

[0062] In order to avoid the occurrence of the above-mentioned jamming situation, in this embodiment, on the one hand, the sheath 5 detection device also includes an anti-jamming mechanism 3, such as Figure 8 As shown, the anti-jamming mechanism 3 is arranged at the feeding point 10 of the conveying unit 1, and includes a pair of relatively arranged fixed baffles 31, a movable baffle 32 and a sensing structure 33; the fixed baffle 31 and the movable baffle 32 are relatively arranged to form a moving channel for the sleeve 5 to pass through, and the outlet of the moving channel is arranged corresponding to the starting end of the conveying route 13, and the sleeve 5 moves to the starting end of the conveying route 13 through the moving channel; the movable baffle 32 is arranged corresponding to the sensing structure 33.

[0063] In this embodiment, when there is no material jam, the movable baffle 32 is within the sensing range of the sensing structure 33, and the sensing structure 33 can sense the movable baffle 32. When there is material jam, the movable baffle 32 is pushed out of the sensing range of the sensing structure 33. At this time, the sensing structure 33 cannot sense the movable baffle 32, and the sheath 5 detection device in this embodiment determines that the device is jammed.

[0064] In other embodiments, when there is no material jam, the movable baffle 32 is outside the sensing range of the sensing structure 33, and the sensing structure 33 cannot sense the movable baffle 32. When there is material jam, the movable baffle 32 is pushed into the sensing range of the sensing structure 33, and the sensing structure 33 can sense the movable baffle 32. The sheath 5 detection device in this embodiment determines that the device is jammed.

[0065] In this embodiment, the movable baffle 32 has a connecting end 321 and a driving end 322. The driving end 322 performs a rotational motion around the connecting end 321, and the rotational motion is a motion close to or away from the sensing structure 33. The movable baffle 32 is connected to a sensing plate 34. Optionally, the sensing plate 34 is fixedly connected to the movable baffle 32, or is integrally formed with the movable baffle 32. When the sheath 5 is stuck, the movable baffle 32 drives the sensing plate 34 to move in a direction close to or away from the sensing structure 33 under the pressure of the stuck sheath 5. Optionally, the sensing structure 33 is a proximity sensor.

[0066] Optionally, the anti-stuck material mechanism 3 further includes an alarm structure. After a set period of time has passed since the material is stuck, the sensor structure 33 triggers the alarm structure to sound an alarm.

[0067] Among them, the above-mentioned set time is the maximum time for the stuck material sleeve 5 to recover to the normal state by itself. In some application scenarios, the stuck material sleeve 5 may recover to normal by itself in a relatively short time, and there is no need to trigger the alarm structure at this time. It can be understood that if the stuck material sleeve 5 is in the stuck state for more than the set time, there is a very small possibility that the stuck material sleeve 5 will recover to normal by itself. If the equipment continues to be allowed to get stuck, this may cause damage to important parts of the equipment.

[0068] Optionally, the alarm structure may be a sound alarm. When the sensing structure 33 fails to sense the sensing plate 34 for a set period of time, the sound alarm emits an alarm sound, and the sheath 5 detection device shuts down to remind the operator to check the jamming situation.

[0069] Optionally, the alarm structure may also be a light alarm. When the sensing structure 33 fails to sense the sensing plate for a set period of time, the light alarm emits a warning light, and the sheath 5 detection device shuts down to remind the operator to check the jammed material.

[0070] Optionally, the alarm structure may also be a composite structure of a sound alarm and a light alarm, which can avoid the drawback that a simple sound alarm and a light alarm cannot effectively alarm when the light is too strong or the noise is too loud.

[0071] When the technician eliminates the danger caused by the jamming of the sheath 5, the technician can manually reset the anti-jamming mechanism 3, or the anti-jamming mechanism 3 can be automatically reset. In a preferred embodiment, the anti-jamming mechanism 3 also includes a reset structure 35 and a limit plate 36, the limit plate 36 is fixedly arranged on the bearing device 11, and limits the distance between the sensing plate 34 and the sensing structure 33; the reset structure 35 includes a reset spring 351 and a push rod 352 connected to the reset spring 351, the push rod 352 is against the sensing plate 34, when the sheath 5 is jammed, the reset spring 351 is compressed under the movement of the sensing plate 34, and the sensing plate 34 is out of the detection range of the sensing structure 33 at this time, after the jamming sheath 5 disappears, the reset spring 351 provides a rebound force to the push rod 352, driving the sensing plate 34 to move to contact the limit plate 36, so that the sensing plate 34 returns to the detection range of the sensing structure 33.

[0072] In this embodiment, a material blocking mechanism 6 is also included. Figure 1 and Figure 4As shown, the material blocking mechanism 6 includes a material blocking plate 61, which is arranged on the first detection disk 111 outside the conveying route 13, and the distance between the material blocking plate 61 and the first detection disk 111 is smaller than the distance between the top of the sheath 5 and the first detection disk 111. Therefore, in some application scenarios, the sheath 5 is not supported by the second bearing structure of the second detection disk 112 and remains in the tooth socket 113 of the toothed disk. When the sheath 5 moves to the material blocking plate 61, it can be intercepted and peeled off by the material blocking plate 61, thereby preventing the sheath 5 from moving to the entrance of the conveying route 13 and getting stuck.

[0073] In this embodiment, the sheath 5 detection device further includes a collection unit 4, which includes a rejection device 41 and a discharge device 42. The rejection device 41 and the discharge device 42 are arranged on the conveying route 13 after the multiple detection devices. The rejection device 41 collects defective sheaths 5 that are defined as defective by one or more of the detection devices; the discharge device 42 collects good sheaths 5 that are defined as good by multiple detection devices. Figure 1 and Figure 2 As shown, the rejecting device 41 and the discharging device 42 are both arranged on the second inspection tray 112 .

[0074] The working process of the existing utility model is as follows:

[0075] The carrying device 11 includes a first testing tray 111 and a second testing tray 112. The first testing tray 111 and the second testing tray 112 respectively have a first carrying structure and a second carrying structure. Each carrying structure is used to carry a sheath 5 to be tested, and the first carrying structure and the second carrying structure are continuously and uninterruptedly arranged along the conveying route 13.

[0076] The first bearing structures and the second bearing structures corresponding to the two detection plates jointly define a handover position 115. When each first bearing structure passes through the handover position 115, there is a corresponding second bearing structure passing through the handover position 115 at the same time, so the sheath 5 can switch positions from the first bearing structure to the second bearing structure;

[0077] The first inspection tray 111 and the second inspection tray 112 are provided with inspection devices along the conveying route 13, each inspection device includes an inspection camera, and the inspection camera included in each inspection device forms an inspection area. When the sheath 5 moves to any inspection device along the conveying route 13, the inspection area of ​​the current inspection device covers the sheath 5 and inspects the sheath 5;

[0078] The sheath 5 moves along the conveying route 13 and passes through the various detection devices arranged on the first detection tray 111 and the second detection tray 112 in sequence. The sheath 5 that has completed the detection is divided into good or defective, and the good sheath is collected by the discharging device 42, and the defective sheath is collected by the rejecting device 41.

[0079] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
