[0022] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0023] As Figures 1 to 7 shown in the embodiment of the glass bottle body defect detection device of the present utility model, the glass bottle body defect detection device includes a tray 1 and a camera 2 disposed below the tray 1. The tray cavity 102 of the tray 1 is used to place the glass bottle; below the tray cavity 102, along the linear forward direction of the tray 1, there is a camera slot 101 passing through the tray 1; the camera slot 101 communicates with the tray cavity 102 in the direction perpendicular to the linear forward direction of the tray 1 (and does not communicate in the linear forward direction of the tray 1 to prevent the camera lens 21 of the camera 2 from entering the tray cavity 102 and causing damage to the camera lens 21). The camera lens 21 of the camera 2 is slidably disposed in the camera slot 101, and when the camera lens 21 slides, its central axis will coincide with the central axis of the glass bottle.

[0024] In an embodiment of the present application, preferably, as Figure 2 、 Figure 3 shown, a clamping assembly 3 is disposed in the tray 1. The clamping assembly 3 includes a lead screw 31, a sliding plate 32, and a clamping ring 33; specifically, please refer to Figure 5 、 Figure 6 again. The lead screw 31 is rotatably disposed in a lead screw slot 1031 in the tray 1 through a bearing. Above the connection between the sliding plate 32 and the lead screw 31, there is a sliding block 321. The sliding block 321 can slide in a sliding block slot 1033 of the tray 1. The sliding plate 32 then slides in a sliding plate slot 1032 that communicates with the sliding block slot 1033 and the tray cavity 102 and the tray cavity 102. The height of the sliding plate slot 1032 is lower than that of the sliding block slot 1033; there are two symmetrically arranged thread lines 311 on the lead screw 31. The sliding plate 32 is controlled by the lead screw 31 through cooperation with the thread lines 311 to move the sliding plates 32 respectively disposed on the two thread lines 311 closer to or farther away from each other; there is a threaded hole below the sliding block 321 on the sliding plate 32, and the threaded hole cooperates with the thread lines 311; the clamping ring 33 is semi-circular, and the clamping ring 33 is fixedly connected to the sliding plate 32 by means of bolts or the like. By using a replaceable clamping ring 33 such as bolts, clamping rings 33 of different shapes can be used to deal with different types of glass bottles to improve the applicability of the device; in addition, the distances between the two clamping rings 33 from the center of the tray cavity 102 and from the camera slot 1101 are equal to achieve the purpose of centering the glass bottle; when the lead screw 31 rotates, the sliding plate 32 is affected by the thread lines 311, and the sliding plate 32 drives the clamping ring 33 to clamp the glass bottle and make the glass bottle centered in the tray cavity 102, so that the central axis of the glass bottle can coincide with the central axis of the camera lens 21.

[0025] In an embodiment of the present application, preferably, as Figures 1 to 3 shown, the clamping ring 33 is disposed in the tray cavity 102. There are two tray cavities 102 in one tray 1, and two pairs of clamping rings 33 are correspondingly arranged. In this way, a set of screw rod 31 and sliding plate 32 can control the two pairs of clamping rings to complete the clamping work, which can save the workload during the clamping work.

[0026] In an embodiment of the present application, preferably, as Figures 1 to 3 shown, one end of the screw rod 31 extends out of the tray 1 and a toothed ring 312 is provided at this end. The toothed ring 312 is used to drive the screw rod 31 to rotate. After the glass bottle is loaded into the tray 1, the toothed ring 312 can be rotated manually or mechanically to clamp the glass bottle and make the glass bottle centered in the tray cavity 102.

[0027] In an embodiment of the present application, preferably, as Figure 4 、 Figure 5As shown in the figure, a pawl assembly 4 is further provided in the tray 1 for locking the rotation of the lead screw 31 in one direction. It should be noted that this rotation direction is the rotation direction in which the lead screw 31 drives the clamping rings 33 to move away from each other (i.e., releasing the clamping of the glass bottle), while the pawl assembly 4 does not restrict the rotation of the lead screw 31 in the other direction to drive the clamping rings 33 to approach each other (i.e., clamping the glass bottle). The pawl assembly 4 includes a ratchet wheel 41, a pawl 42, and a locking pin 43. The ratchet wheel 41 is fixedly provided on the outer wall of the lead screw 31. Correspondingly, a ratchet wheel groove 1041 for avoiding the ratchet wheel 41 and communicating with the lead screw groove 1031 is provided in the tray 1. The outer circumference of the ratchet wheel 41 is provided with the pawl 42. The pawl 42 is rotatably provided in the pawl groove 1042 of the tray 1. The pawl groove 1042 communicates with the ratchet wheel groove 1041. The pawl 42 is subjected to the acting force of a torsion spring and thus has a tendency to lock the ratchet wheel 41. In the rotation direction for unlocking the ratchet wheel 41 by the pawl 42, a locking groove 1043 into which the locking pin 43 can be inserted is provided. The locking groove 1043 communicates with the pawl groove 1042. The pawl 42 can be turned into the locking groove 1043. The locking groove 1043 extends out of the tray 1 on one side in the axial direction of the pawl 42 and extends into the tray 1 on the other side. A spring 44 is provided in the locking groove 1043 extending into the tray 1. The locking pin 43 abuts against the spring 44. One end of the locking pin 43 extending out of the tray 1 is restricted by a locking cover 1044 (the end of the locking pin 43 away from the spring 44 is a locking end 432 that cooperates with the locking cover 1044 for installing the locking pin 43). An unlocking groove 431 is provided on the locking pin 43. Therefore, pressing the locking pin 43 can release the limit of the pawl 42 to unlock the rotation of the ratchet wheel 41. Specifically, when the locking pin 43 is not pressed from outside the tray 1, the locking pin 43 is pushed by the spring 44, and the unlocking groove 431 does not communicate with the ratchet wheel groove 1042. Therefore, the ratchet wheel 42 cannot be turned into the unlocking groove 431. At this time, it is the locking state of the pawl assembly 4. When the locking pin 43 is pressed from outside the tray 1, the locking pin 43 compresses the spring 44. Then, the unlocking groove 431 communicates with the ratchet wheel groove 1042. Therefore, the ratchet wheel 42 is turned into the unlocking groove 431. At this time, it is the unlocking state of the pawl assembly 4, and the lead screw 31 can make the clamping rings 33 move away from each other, and the clamping of the glass bottle can be released.

[0028] In an embodiment of the present application, preferably, as Figure 1 shown, the device further includes a track 5. The tray 1 is conveyed by the track 5. The camera 2 is fixedly provided on the base of the track 5. The distances of the front and rear parts of the track 5 where the camera 2 is located are both set as straight tracks, and the distance between the front and rear parts is greater than the length of the tray 1. In this embodiment, when the tray 1 is conveyed by the track 5, the camera head 21 will slide in the camera groove 101 of the tray 1. If the distances of the front and rear parts of the track 5 where the camera 2 is located are curved, it will cause damage to the camera head 21.

[0029] In an embodiment of the present application, preferably, as Figure 1As shown in the figure, the device further includes a light source 6, which is horizontally arranged above the track 5, and the vertical distance between the light source 6 and the camera 21 is greater than the height of the glass bottle to avoid interference.

[0030] In an embodiment of the present application, preferably, as Figure 7 shown in the figure, the device further includes a bottle body camera 2c for horizontally photographing the glass bottle and a supporting bottle body light source 6c arranged on both sides of the track 5, which can detect other possible defects that cannot be detected by the camera 2, such as the height of the bottle body of the glass bottle.

[0031] The working principle of the present utility model: The tray 1 of the device is conveyed by the track 5, and the clamping assembly 3 fixes the glass bottle at the central position of the tray cavity 101 of the tray 1, and the clamping assembly 3 is locked by the ratchet pawl assembly 4; when the tray 1 passes through the track 5 where the camera 2 is arranged, the camera 21 of the camera 2 will slide into the camera slot 101. When the camera 21 reaches directly below the glass bottle and coincides with the central axis of the glass bottle, the light source 6 flashes to illuminate the glass bottle body and the camera 2 takes a photo of the inside of the bottle body from directly below the glass bottle; after the shooting work is completed and the specific position is reached, the ratchet pawl assembly 4 unlocks the clamping assembly 3 to take out the glass bottle.

[0032] The device is provided with a tray 1 and a clamping assembly 3 is arranged in the tray 1 to clamp different types of glass bottles, which increases the applicable range of the device and makes the position of the glass bottle centered so that the camera 2 can accurately take pictures; a locking assembly 4 is arranged in the tray 1 to ensure the safety of the transportation of the glass bottle; the camera 2 is arranged below the tray 1 and photographs the glass bottle body through the bottom of the bottle, which can effectively avoid the problem of difficult detection of possible defects on the bottle body caused by irregular concave and convex patterns on the special glass bottle body.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
