[0002] At present, when it is necessary to collect information on the outer surface of columnar materials in batches, such as collecting barcode information on multiple test tubes or collecting appearance parameter information on the outer surface of multiple cans, the following two methods are generally used.

[0042] See also Figure 1 and Figure 2 The detection device 1 and the rotating device 10 provided in the embodiment of the present application are now described. The detection device 1 includes the rotating device 10 and the information collector 20. The material 0 with at least a part of the outer surface being a cylindrical surface is fed along the feeding direction (see Figure 2 in the direction indicated by the arrow in the middle) to the rotating station A (see Figure 2 ), the rotating device 10 is used to rotate the material 0 entering the rotating station A, and the information collector 20 is used to collect information on the outer surface of the material 0 when the material 0 rotates. The rotating device 10 includes a bracket 100, a rotating mechanism 200 and a pre-pressing mechanism 300, wherein the bracket 100 is provided with first axes 110 (see Figure 7 ) and the second shaft 120 (see Figure 4 ), and the first axis 110 and the second axis 120 are located on both sides of the feeding direction of the material 0; the rotating mechanism 200 includes a rotating wheel 210, which is rotatably arranged on the first axis 110 and is used to abut against the outer surface of the material 0 to rotate the material 0; the pre-pressing mechanism 300 includes a pre-pressing arm 310, two pre-pressing wheels 320 and a position adjustment component 330, the pre-pressing arm 310 is rotatably mounted on the second axis 120, the two pre-pressing wheels 320 are arranged on the pre-pressing arm 310, and the position adjustment component 330 is used to provide an elastic force to the pre-pressing arm 310. When the material 0 is located in the rotating station A, the position adjustment component 330 enables the pre-pressing arm 310 to drive the two pre-pressing wheels 320 to elastically press against the outer surface of the material 0. After the material 0 leaves the rotating station A, the position adjustment component 330 resets the pre-pressing arm 310.

[0043] It should be noted that material 0 can be a columnar material such as a test tube or a can. When the rotating device 10 provided in this embodiment is working, material 0 can be arranged in batches on the feeding mechanism along the feeding direction. Under the action of the feeding mechanism, material 0 enters the rotating station A in turn, and leaves the rotating station A in turn after completing the rotation at the rotating station A.

[0044] It should be noted that the pre-pressing wheel 320 can be fixedly arranged on the pre-pressing arm 310 or rotatably arranged on the pre-pressing arm 310. Compared with being fixedly arranged on the pre-pressing arm 310, when the pre-pressing wheel 320 is rotatably arranged on the pre-pressing arm 310, the sliding friction between the pre-pressing wheel 320 and the material 0 can be converted into rolling friction, so that the material 0 can enter and exit the rotating station A more smoothly.

[0045] It should also be noted that the first axis 110 of the rotating wheel 210 can be fixedly set on the bracket 100, or can be set on the bracket 100 close to or away from the rotating station A. Compared with the case where the first axis 110 of the rotating wheel 210 is fixedly set on the bracket 100, when the first axis 110 of the rotating wheel 210 is movably set on the bracket 100, the rotating wheel 210 can move in the direction away from the rotating station A before the material 0 enters the rotating station A, making more space for the material 0, making it easier for the material 0 to enter the rotating station A, and after the material 0 enters the rotating station A, it moves in the direction close to the rotating station A until it abuts against the outer surface of the material 0, thereby driving the material 0 to rotate normally.

[0046] Compared with the related art, the rotating device 10 provided in this embodiment is such that before the material 0 enters the rotating station A, the pre-pressing arm 310 and the pre-pressing wheel 320 are in the initial position under the action of the position adjustment component 330 (see Figure 5 1 and 12. The position of the pre-pressing arm 310 is shown by the solid line in the middle. When the material 0 enters the rotating station A along the feeding direction, the material 0 pushes the pre-pressing wheel 320, and the pre-pressing wheel 320 drives the pre-pressing arm 310 to rotate around the second axis 120. The pre-pressing arm 310 and the pre-pressing wheel 320 make more space for the material 0. After the material 0 completely enters the rotating station A, the pre-pressing arm 310 and the pre-pressing wheel 320 are kept in a position where the pre-pressing wheel 320 can abut against the outer surface of the material 0 under the action of the position adjustment component 330 (see Figure 5The position of the pre-pressing arm 310 shown by the dotted line in the middle), then, the rotating wheel 210 abuts against the outer surface of the material 0 and drives the material 0 to rotate. After the material 0 completes the rotation and leaves the rotating station A, the pre-pressing arm 310 and the pre-pressing wheel 320 return to the initial position under the action of the position adjustment component 330, and the rotating device 10 can continue to rotate the next material 0. The rotating device 10 provided in the present application is provided with two pre-pressing wheels 320 on the rotatable pre-pressing arm 310, and the position of the pre-pressing arm 310 is adjusted by the position adjustment component 330. When the material 0 is located in the rotating station A, the pre-pressing wheel 320 can abut against the outer surface of the material 0 and cooperate with the rotating wheel 210 to complete the rotation operation. When the material 0 enters and exits the rotating station A, the pre-pressing wheel 320 and the pre-pressing arm 310 can change their position on the bracket 100 under the push of the material 0, making room for the material 0 to move, so that the material 0 can "flexibly" enter and exit the rotating station A, and it is not easy to get stuck.

[0047] In addition, compared with the method in which the pre-pressing wheel 320 is fixedly arranged on the bracket 100 in the related art, the rotating device 10 provided in this embodiment can be suitable for materials 0 of different diameters, because the positions of the pre-pressing wheel 320 and the pre-pressing arm 310 on the bracket 100 can be changed under the action of the material 0 and the position adjustment component 330, and has a wider range of adaptability.

[0048] Optionally, the two pre-pressing wheels 320 and the rotating wheel 210 are located on the same plane.

[0049] Optionally, the outer surface of the rotating wheel 210 can be wrapped with a polyurethane protective layer or a rubber protective layer; the outer surface of the rotating wheel 210 can also be provided with a mounting groove (not shown in the figure), and a polyurethane O-ring or a rubber O-ring is provided in the mounting groove. The above structure can minimize damage to the surface of the material 0 and the outer surface of the rotating wheel 210.

[0050] Optionally, the rotation speed of the rotating wheel 210 is 50 rpm-200 rpm. Setting the rotation speed of the rotating wheel 210 within the above range can ensure that the material 0 rotates at a suitable rotation speed, making it easier for the information collector 20 to collect information on the outer surface of the material 0.

[0051] In another embodiment of the present application, please refer to Figure 3 and Figure 4 The position adjustment assembly 330 includes a mounting seat 331, a guide rod 332 and an elastic member 333. The mounting seat 331 is provided with a second shaft 120. The mounting seat 331 also has a first limiting surface 3311 (see Figure 6); one end of the pre-pressing arm 310 is connected to two pre-pressing wheels 320, and the other end of the pre-pressing arm 310 is provided with a slide groove 311; the first end of the guide rod 332 is slidably matched with the slide groove 311, and the second end of the guide rod 332 is fixed to the mounting seat 331; the elastic member 333 is sleeved on the guide rod 332 and abuts between the mounting seat 331 and the pre-pressing arm 310. After the material 0 leaves the rotating station A, the pre-pressing arm 310 abuts against the first limiting surface 3311 under the action of the elastic member 333.

[0052] It should be noted that the elastic member 333 abutting between the mounting seat 331 and the pre-stressing arm 310 can be understood as, when the second end of the guide rod 332 is arranged on the side of the pre-stressing arm 310 close to the rotating station A, the elastic member 333 is in a compressed state to achieve the above-mentioned function. At this time, the two ends of the elastic member 333 can respectively abut against the mounting seat 331 and the pre-stressing arm 310, or can be respectively connected to the mounting seat 331 and the pre-stressing arm 310, or one end can be connected to one of the mounting seat 331 and the pre-stressing arm 310, and the other end can abut against the other one of the mounting seat 331 and the pre-stressing arm 310; however, when the second end of the guide rod 332 is arranged on the side of the pre-stressing arm 310 away from the rotating station A, the elastic member 333 is in a stretched state to achieve the above-mentioned function. At this time, the two ends of the elastic member 333 are respectively connected to the mounting seat 331 and the pre-stressing arm 310.

[0053] The rotating device 10 provided in this embodiment has a simple structure and a small size, which greatly saves the cost and design space of the rotating device 10 .

[0054] In another embodiment of the present application, the mounting base 331 includes a base plate 3312 and a pressure plate 3313. The base plate 3312 is mounted on the bracket 100. The base plate 3312 or the pressure plate 3313 has a first limiting surface 3311 (the first limiting surface 3311 is arranged on the pressure plate 3313, which is not shown in the figure). The pressure plate 3313 is movably mounted on the base plate 3312. The moving direction of the base plate 3312 is parallel to the direction from the feed side of the rotating station A to the discharge side of the rotating station A. The pressure plate 3313 is provided with a second axis 120, and the pressure plate 3313 is fixedly connected to the second end of the guide rod 332.

[0055] The rotating device 10 provided in this embodiment can adjust the position of the pre-pressing arm 310 and the pre-pressing wheel 320 installed on the pressing plate 3313 by changing the position of the pressing plate 3313 on the base plate 3312, so that the pre-pressing wheel 320 is pressed against the outer surface of the material 0 at a suitable position, thereby improving the adaptability of the rotating device 10. When the position of the pressing plate 3313 on the base plate 3312 is changed, the positions of the second shaft 120, the pre-pressing arm 310 and the elastic member 333 are changed synchronously, so that the pressure provided by the pre-pressing wheel 320 to the outer surface of the material 0 remains unchanged after the position is adjusted. In this way, there is no need to readjust the pressure provided by the pre-pressing wheel 320 to the material 0 after the position of the pre-pressing wheel 320 is changed, so that the rotating device 10 has the advantage of being easy to adjust. In addition, the rotating device 10 provided in this embodiment reduces the corresponding motor or cylinder drive mechanism, has a simple structure, low cost, small size, and is conducive to compact product design.

[0056] Optionally, a limiting groove 3314 is provided on the top of the base plate 3312, and the limiting groove 3314 penetrates the base plate 3312 along the feeding direction of the material 0, and the limiting groove 3314 is used for the pre-pressing arm 310 to be placed, and the two side walls of the limiting groove 3314 are respectively provided with a first limiting surface 3311 parallel to the feeding direction of the material 0 (see Figure 6 ), the pressing plate 3313 includes a horizontal portion 3315 and a vertical portion 3316 connected to each other, the horizontal portion 3315 is buckled on the top of the base plate 3312, the vertical portion 3316 is connected to the bottom of the horizontal portion 3315 and is located on the side of the base plate 3312 close to the rotating station A, and a second shaft 120 is also provided at the bottom of the horizontal portion 3315, the pre-pressing arm 310 is sleeved in the limiting groove 3314 and the second end of the pre-pressing arm 310 corresponds to the position of the vertical portion 3316, the second end of the guide rod 332 is fixedly connected to the vertical portion 3316, the first end of the guide rod 332 is slidably connected to the slide groove 311 of the pre-pressing arm 310, and the elastic member 333 is sleeved on the guide rod 332 and abuts between the vertical portion 3316 and the pre-pressing arm 310.

[0057] Optionally, please refer to Figures 331 and 331, the pressing plate 3313 is provided with an elongated hole 3319 extending in the feeding direction, and the base plate 3312 is provided with a screw hole (not shown) corresponding to the elongated hole 3319. In this way, the pressing plate 3313 can be installed on the base plate 3312 by inserting the threaded connector into the elongated hole 3319 of the pressing plate 3313, and one end of the threaded connector inserted into the elongated hole 3319 is connected to the screw hole on the base plate 3312. When the position of the pressing plate 3313 on the base plate 3312 needs to be adjusted, the threaded connector is loosened, the pressing plate 3313 is moved to a suitable position along the feeding direction of the material 0, and the threaded connector is re-tightened, and the adjustment operation is simple and convenient.

[0058] Optionally, the position adjustment component 330 may include a torsion spring (not shown), which is sleeved on the second shaft 120, and one end of the torsion spring abuts against the bracket 100, and the other end of the torsion spring abuts against the pre-pressing arm 310. When the material 0 is not in the rotating station A, the pre-pressing arm 310 and the pre-pressing wheel 320 are in an initial position under the action of the torsion spring. When the material 0 enters the rotating station A along the feeding direction, the material 0 pushes the pre-pressing wheel 320 at the initial position, and the pre-pressing wheel 320 pushes the pre-pressing arm 310 to rotate around the second shaft 120 and squeezes the torsion spring until the material 0 completely enters the rotating station A. At this time, under the action of the elastic force of the torsion spring, the pre-pressing wheel 320 on the pre-pressing arm 310 abuts against the outer surface of the material 0, and then the material 0 passively rotates driven by the rotating wheel 210, and then the material 0 leaves the rotating station A along the feeding direction, and the pre-pressing arm 310 and the pre-pressing wheel 320 will be reset to the initial position under the action of the elastic force of the torsion spring.

[0059] In another embodiment of the present application, please refer to Figure 6 The mounting seat 331 also has a second limiting surface 3317, which is used to abut against the pre-pressing arm 310 to limit the end of the pre-pressing arm 310 provided with the pre-pressing wheel 320 from moving in a direction away from the rotating station A.

[0060] It should be noted that the second limiting surface 3317 can be a single surface or two or more parallel surfaces, and can be set as needed, which is not a sole limitation here.

[0061] Optionally, when the mounting portion includes the above-mentioned base plate 3312 and the pressing plate 3313, the second limiting surface 3317 is arranged on the side wall of the above-mentioned limiting groove 3314.

[0062] In the rotating device 10 provided in this embodiment, the second limiting surface 3317 cooperates with the first limiting surface 3311 to limit the rotation of the pre-stressing arm 310 within a certain range, which can minimize the volume of the rotating device 10, and the second limiting surface 3317 can prevent the elastic member 333 from being overly compressed or over-stretched due to the end of the pre-stressing arm 310 provided with the pre-stressing wheel 320 rotating too much in the direction away from the rotating station A.

[0063] In another embodiment of the present application, please refer to Figure 4 The position adjustment assembly 330 further includes an adjustment wheel 334 , which is sleeved on the guide rod 332 and can move along the axial direction of the guide rod 332 , and the elastic member 333 abuts between the adjustment wheel 334 and the pre-compression arm 310 .

[0064] It should be noted that the adjusting wheel 334 can be arranged on the guide rod 332 in a variety of ways. For example, taking the case described in the above embodiment where the end of the guide rod 332 away from the pre-pressing arm 310 is arranged on the side of the pre-pressing arm 310 close to the rotating station A, and the elastic member 333 is in a compressed state, the adjusting wheel 334 is provided with a thread, the guide rod 332 is provided with an external thread adapted to the internal thread, and the adjusting wheel 334 is sleeved on the portion of the guide rod 332 provided with the external thread. The adjusting wheel 334 is rotated to move the adjusting wheel 334 on the guide rod 332 toward the direction close to the pre-pressing arm 310, which can shrink the elastic member 333, thereby increasing the pressure of the pre-pressing wheel 320 on the pre-pressing arm 310 on the outer surface of the material 0; the adjusting wheel 334 is rotated to move the adjusting wheel 334 on the guide rod 332 away from the pre-pressing arm 310, which can extend the elastic member 333, thereby reducing the pressure of the pre-pressing wheel 320 on the pre-pressing arm 310 on the outer surface of the material 0. For another example, the adjusting wheel 334 can be slidably mounted on the guide rod 332, and a row of positioning holes (not shown) are axially arranged on the guide rod 332. After the adjusting wheel 334 is moved to a desired position, a positioning piece (not shown) can be inserted into the positioning hole located on the side of the adjusting wheel 334 away from the pre-stressing arm 310, and the adjusting wheel 334 can be fixed at the desired position using the positioning piece.

[0065] The rotating device 10 provided in this embodiment can adjust the pressing force of the pre-pressing wheel 320 on the material 0 by changing the position of the adjusting wheel 334 on the guide rod 332, which greatly reduces the difficulty of adjusting the pre-pressing force, and the device has a simple structure and is easy to operate.
