Description

Technical Field

[0001] This utility model relates to the field of production testing technology, specifically to a height adjustment device for an empty can testing camera. Background Technology

[0002] In beverage bottling workshops, empty can inspection equipment is typically installed on the production line to check the quality of empty cans. This equipment includes an inspection camera that takes pictures of the bottom, body, and mouth of the empty can and transmits these images as data to a screening system. The screening system then filters the images to ensure that the empty cans shown in the pictures are free of defects. The inspection camera is positioned above the empty cans to inspect them. When changing to cans of different heights, the height of the inspection camera needs to be adjusted to match the height of the empty cans. In existing technology, the height of the inspection camera is usually adjusted using shims. By changing shims of different heights, the height of the inspection camera is adjusted. Since there are many types of empty cans with varying heights, multiple shims of different heights need to be prepared. However, a large number of shims can easily lead to loss, and it also consumes a lot of time to find the corresponding shims, affecting production efficiency. Utility Model Content

[0003] In view of this, the present invention provides a height adjustment device for an empty can detection camera to solve the problem that when there are many pads, they are easily lost, and at the same time, a lot of time is spent searching for the corresponding pads, which affects production efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, a height adjustment device for an empty can detection camera is provided, comprising: a lifting assembly 1, a camera support frame 2, and a drive structure 3.

[0030] Specifically, the lifting assembly 1 includes a first lifting platform 11 and a second lifting platform 12, which are arranged at intervals relative to each other. A first guide structure 111 and a second guide structure 121 are respectively provided on the first lifting platform 11 and the second lifting platform 12, and the guiding directions of the first guide structure 111 and the second guide structure 121 are the same. The camera support frame 2 has a mounting position 21, through which the camera is fixedly mounted on the camera support frame 2, so that the camera is positioned above and opposite the object to be inspected. Both ends of the camera support frame 2 are slidably connected to the first guide structure 111 and the second guide structure 121, respectively. A drive structure 3 is disposed on the first lifting platform 11 and / or the second lifting platform 12, and is connected to the camera support frame 2 to drive the camera support frame 2 to move relative to each other along the guiding directions of the first guide structure 111 and the second guide structure 121.

[0031] In this embodiment, the first lifting platform 11 and the second lifting platform 12 are spaced apart and located on both sides of the tank conveyor belt (not shown). The first guide structure 111 and the second guide structure 121 are arranged opposite to each other and extend vertically. The two ends of the camera support frame 2 are slidably connected to the first guide structure 111 and the second guide structure 121, respectively. The mounting position 21 on the camera support frame 2 is located directly above the tank. The camera installed in the mounting position 21 is positioned opposite to the tank to be tested. The camera support frame 2 can slide relative to the first guide structure 111 and the second guide structure 121 along their guiding directions, thereby driving the mounting position 21 and the camera (not shown) on the mounting position 21 to rise and fall to adjust the height of the camera. The driving structure 3 is installed on the first lifting platform 11 and can drive the end of the camera support frame 2 that is slidably connected to the first guide structure 111 to move. The end of the camera support frame 2 that is slidably connected to the second guide structure 121 is driven. In other optional embodiments, the driving structure 3 can be installed on the second lifting platform 12.

[0032] Specifically, the camera is an industrial camera.

[0033] By setting a first guide structure 111 and a second guide structure 121 on the first lifting platform 11 and the second lifting platform 12, the two ends of the camera support frame 2 are slidably connected to the first guide structure 111 and the second guide structure 121 respectively. The driving structure 3 drives the camera support frame 2 to move relative to each other, thereby adjusting the height of the camera support frame 2 and thus adjusting the height of the camera on the mounting position 21. This avoids the need to prepare multiple pads of different heights, and also saves adjustment time and improves production efficiency.

The lead screw 32 can be rotated through the handle 31. When the lead screw 32 rotates, one end of the camera support frame 2 can move relative to the lead screw 32 along the guide direction of the lead screw 32.

[0036] Preferably, the handle 31 is a wheel. In other alternative embodiments, the handle 31 may also be a handle.

[0037] In this embodiment, as Figure 2As shown, a first slider 4 is provided on the lead screw 32, and the first slider 4 is slidably connected to the lead screw 32. One end of the camera support frame 2 is fixedly connected to the first slider 4.

[0038] In one embodiment, the camera support frame 2 includes a first connector 22, a second connector 23, and a camera positioning member 24. The mounting position 21 is disposed on the camera positioning member 24. The first connector 22 and the second connector 23 are respectively disposed on both sides of the camera positioning member 24. The two ends of the first connector 22 are fixedly connected to the first slider 4 and the camera positioning member 24, respectively. One end of the second connector 23 is fixedly connected to the camera positioning member 24, and the other end of the second connector 23 is slidably connected to the second guide structure 121.

[0039] In this embodiment, as Figure 1 and Figure 5 As shown, in Figure 5 The first connector 22 and the second connector 23 are located on the left and right sides of the camera positioning component 24, respectively. The right end of the first connector 22 overlaps with the upper surface of the camera positioning component 24, and the left end of the second connector 23 overlaps with the upper surface of the camera positioning component 24. The bolt 6 passes through the right end of the first connector 22 to fix the right end of the first connector 22 to the upper surface of the camera positioning component 24, and the bolt 6 passes through the left end of the second connector 23 to fix the left end of the second connector 23 to the upper surface of the camera positioning component 24.

[0040] In this embodiment, as Figure 3 and Figure 4 As shown, the second guide structure 121 is a slide rail, on which a second slider 5 is slidably connected, and the other end of the second connector 23 is fixedly connected to the second slider 5.

[0041] In this embodiment, as Figure 1 and Figure 5 As shown, the end of the first connector 22 connected to the first slider 4 has a first bend 25, which is perpendicular to the first connector 22. The first bend 25 is fixedly connected to the first slider 4 by bolts 6. The end of the second connector 23 connected to the second slider 5 has a second bend 26, which is perpendicular to the second connector 23. The second bend 26 is fixedly connected to the second slider 5 by bolts 6.

[0042] In one embodiment, a limit component 7 is provided on the second lifting platform 12, which is used to limit the second slider 5.

[0044] Specifically, multiple positioning holes 71 are arranged at intervals. Preferably, the spacing between adjacent positioning holes 71 is the same. In other alternative embodiments, the spacing between adjacent positioning holes 71 may be different. The number of positioning holes 71 can be determined according to the length of the slide rail, and is not specifically limited here.

[0045] In this embodiment, as Figure 2 As shown, a mechanical counter 8 is installed on the lead screw 32. During the rotation of the rotating wheel, the mechanical counter 8 displays a corresponding number based on the number of revolutions of the lead screw 32. The number displayed by the mechanical counter 8 varies depending on the camera's height. The number displayed by the mechanical counter 8 represents the relative height of the camera, not its absolute height. In the initial debugging phase, empty cans of different heights are used to determine the optimal camera position, and the numbers displayed on the mechanical counter 8 are recorded. This method is used to record the numbers for several commonly used cans of different heights in production. Later, when changing cans of different heights, the camera is directly adjusted to the recorded predetermined position, i.e., the position displayed by the number on the mechanical counter 8.

[0046] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
