[0035] Please see Figures 1 to 4 One embodiment of this utility model provides an automatic positioning and feeding mechanism for a fully automatic roller printing machine, including: a bracket 10, a guide rail 20, a positioning fixture 30, a pressing member 40, and a rotary propulsion assembly 50.

[0036] The guide rail 20 is set on the support 10, and a positioning space 21 is set at the end of the guide rail 20. It should be noted that the starting point and the ending point of the guide rail 20 are at both ends of the guide rail 20, and the workpiece 60 is transported from the starting point of the guide rail 20 to the ending point of the guide rail 20.

[0037] The positioning fixture 30 is used for positioning and cooperating with the workpiece 60, and the positioning fixture 30 is provided with a limiting part 31 for circumferential limiting and cooperating with the workpiece 60.

[0038] The pressing component 40 and the positioning fixture 30 are respectively disposed on both sides of the positioning space 21.

[0039] The rotary propulsion assembly 50 is used to drive the pressing member 40 to translate and rotate. The pressing member 40 is configured to push the workpiece 60 located in the positioning space 21 toward the positioning fixture 30 and drive the workpiece 60 to rotate relative to the positioning fixture 30 under the drive of the rotary propulsion assembly 50.

[0040] The guide rail 20 can be connected to the source of the workpiece 60, for example, the guide rail 20 can be connected to a screening machine. The workpiece 60 is conveyed along the starting point of the guide rail 20 to the ending point of the guide rail 20, so that the workpiece 60 enters the positioning space 21. Then the rotary propulsion assembly 50 drives the pressing member 40 to move toward the positioning fixture 30. The pressing member 40 presses the workpiece 60 against the positioning fixture 30. Then the pressing member 40 drives the workpiece 60 to rotate, so that the workpiece 60 is relative to the positioning fixture 30 until the workpiece 60 can be circumferentially limited and engaged with the limiting part 31. In this embodiment, a groove 61 is provided on the workpiece 60, and a circumferential limiting groove 62 is provided within the groove 61. The limiting part 31 is a limiting shaft with a D-shaped cross-section. Under the push of the pressing member 40, the workpiece 60 causes the positioning fixture 30 to enter the groove 61. Subsequently, after the workpiece 60 rotates to a suitable angle, the rotary propulsion assembly 50 drives the workpiece 60 to move towards the positioning fixture 30, causing the limiting part 31 to extend into the circumferential limiting groove 62, thus achieving a stable and accurate fit between the workpiece 60 and the positioning fixture 30. Of course, in other embodiments, the workpiece 60 may also have an internal D-shaped shaft, and the positioning fixture 30 may be provided with a corresponding limiting groove that mates with the D-shaped shaft. The limiting part 31 is designed according to the characteristics of the workpiece 60, and is not limited to this example. The end of the limiting part 31 may be chamfered to facilitate the insertion of the limiting part 31 into the circumferential limiting groove 62.

[0041] In some optional embodiments, the guide track 20 extends along an S-shaped path from top to bottom. The starting point of the guide track 20 is above the ending point. The workpiece 60 rolls along the guide track 20 by gravity. If the slope is too steep when the workpiece 60 rolls from a high point to a low point, the inertia of the workpiece 60 will impact the workpiece 60 in front, which may cause the workpiece 60 to be squeezed out laterally, resulting in the workpiece 60 shifting its position relative to the width direction of the guide track 20. The S-shaped extension of the guide track 20 can decelerate the workpiece 60, thus buffering it. In addition, the S-shaped extension of the guide track 20 can also prevent the fully automatic roller printing machine and the screening machine from being too far apart, and a certain number of workpieces 60 can be pre-stored in the S-shaped extension of the guide track 20, so that after the workpiece 60 is positioned, the next workpiece 60 can be positioned quickly.

[0042] In some alternative embodiments, the guide rail 20 is at least partially located on the support 10 and is vertically detachable. By raising and lowering the guide rail 20, the position of the positioning space 21 can be adjusted according to the size of the workpiece 60, so that the workpiece 60 can be accurately aligned with the positioning fixture 30. In this embodiment, the guide rail 20 is rotatably coupled with the bracket 10. The relative rotation of the guide rail 20 allows the portion of the guide rail 20 near the positioning space 21 to swing up and down, thereby achieving lifting and lowering. After rotation, the guide rail 20 is fixed in position with the bracket 10 by threaded locking parts, pins, etc. In this embodiment, the bracket 10 is provided with an arc-shaped groove 22 extending around the rotation axis of the guide rail 20. The screw passes through the arc-shaped groove 22 and is threadedly coupled with the bracket 10 to lock the guide rail 20 onto the bracket 10. When it is necessary to rotate the guide rail 20, the screw is loosened to allow the guide rail 20 to rotate. Of course, in other embodiments, a lifting rail can also be provided on the bracket 10, with the guide rail 20 slidingly coupled with the lifting rail. The guide rail 20 can rise and fall along the lifting rail, and then be fixed in position with the bracket 10 by threaded locking parts, pins, etc.

[0043] Please see Figures 5 to 6 In some optional embodiments, a guide groove 23 extending along the extension direction of the guide track 20 is formed within the guide track 20. The width of the guide groove 23 is greater than the thickness of the workpiece 60, and the difference between the width of the guide groove 23 and the thickness of the workpiece 60 is neither greater than 0.5 mm nor less than 0.05 mm. This small difference allows the guide groove 23 to smoothly guide the workpiece 60 while preventing the workpiece 60 from tilting relative to the guide groove 23 in the vertical direction, thus keeping the workpiece 60 in an upright position. This allows the workpiece 60 to be more accurately aligned with the positioning fixture 30 when positioning. In this embodiment, the difference between the width of the guide groove 23 and the thickness of the workpiece 60 is 0.15 mm.

[0044] In some optional embodiments, the support 10 is provided with a plurality of sensing components 11, with sensing components 11 arranged at the starting point of the guide rail 20 and / or on one side of the positioning space 21. In this embodiment, the support 10 is provided with two sensing components 11, one at the starting point of the guide rail 20 and one on one side of the positioning space 21. The sensing components 11 are mainly used to determine the remaining amount of workpieces 60 in the guide rail 20. When the sensing component 11 on one side of the positioning space 21 detects workpieces 60 but the sensing component 11 at the starting point of the guide rail 20 does not detect workpieces 60, it indicates that the guide rail 20 is not full, and the screening machine can be started to feed the guide rail 20 until the sensing component 11 at the starting point of the guide rail 20 detects workpieces 60. When the sensing component 11 on one side of the positioning space 21 does not detect workpieces 60, it indicates that there are no workpieces 60 in the guide rail 20 and it needs to be replenished as soon as possible. Of course, it is also possible to determine the remaining quantity of workpiece 60 by arranging the sensing component 11 only at the starting point of the guide rail 20. If the sensing component 11 at the starting point of the guide rail 20 does not detect workpiece 60, it means that the guide rail 20 is not full. If the sensing component 11 at the starting point of the guide rail 20 detects workpiece 60, it means that the guide rail 20 is full of workpiece 60. Alternatively, it is also possible to determine the remaining quantity of workpiece 60 by setting the sensing component 11 only on one side of the positioning space 21. If the sensing component 11 on one side of the positioning space 21 detects workpiece 60, it means that there is still workpiece 60 in the guide rail 20. If the sensing component 11 on one side of the positioning space 21 does not detect workpiece 60, it means that there is no workpiece 60 in the guide rail 20 and it needs to be replenished as soon as possible.

[0045] The specific structure of the sensing component 11 can be selected according to actual needs. For example, the sensing component 11 can be an infrared sensor, a photoelectric sensor, or an inductive switch, etc. The principle is well known to those skilled in the art and will not be described in detail here.

[0046] Please see Figure 6In some optional embodiments, after the pressing member 40 drives the workpiece 60 to engage circumferentially with the limiting part 31, the portion of the pressing member 40 abutting against the workpiece 60 is located within the positioning space 21. This ensures that a portion of the workpiece 60 is within the positioning space 21, thereby limiting the position of the next workpiece 60 on the guide rail 20. This prevents the next workpiece 60 from entering the positioning space 21 and affecting the positioning of the current workpiece 60 and the subsequent removal process. It should be noted that, in order to ensure that a portion of the workpiece 60 remains in the positioning space 21 to limit the position of the next workpiece 60 after the workpiece 60 and the positioning fixture 30 are positioned, the position of the positioning fixture 30 also needs to be adaptively adjusted according to the wall thickness of the workpiece 60. This ensures that when the pressing member 40 presses the workpiece 60 onto the positioning fixture 30, the portion of the pressing member 40 abutting against the workpiece 60 and the portion of the workpiece 60 remain within the positioning space 21. In this embodiment, after the workpiece 60 is positioned with the positioning seat, the workpiece 60 extends into the positioning space 21 by approximately 0.5 mm.

[0047] Please see Figure 7 In some optional embodiments, the rotary propulsion assembly 50 includes a translation drive module 51, a movable base 52, and a drive motor 53. The translation drive module 51 is mounted on the support 10 and drivenly connected to the movable base 52. The drive motor 53 is mounted on the movable base 52 and drivenly connected to the pressing member 40. The translation drive module 51 drives the movable base 52 to move, thereby causing the drive motor 53 and the pressing member 40 to reciprocate. The drive motor 53 drives the pressing member 40 to rotate. Of course, the structure of the rotary propulsion assembly 50 is not limited to this. Those skilled in the art can also choose other suitable structures based on the teachings of this utility model. For example, the rotary propulsion assembly 50 includes a translation drive module 51 and a drive motor 53. The drive motor 53 is mounted on the support 10 and drivenly connected to the translation drive module 51. The translation drive module 51 is drivenly connected to the pressing member 40. The drive motor 53 drives the translation drive module 51 and the pressing member 40 to rotate, and the translation drive module 51 drives the pressing member 40 to translate.

[0048] Several slide rails 12 can be installed on the bracket 10, and the movable seat 52 slides with the slide rails 12 to improve the stability of the movable seat 52.

[0049] When the workpiece 60 is positioned, the translation drive module 51 drives the moving seat 52 to move, so that the pressing member 40 moves toward the positioning fixture 30 and presses the workpiece 60 against the positioning fixture 30. Then the drive motor 53 drives the pressing member 40 to rotate, so that the pressing member 40 drives the workpiece 60 to rotate, so that the workpiece 60 corresponds to the angle of the limiting part 31.

[0050] The specific structure of the translation drive module 51 can be designed according to actual needs. For example, the translation drive module 51 can be a lead screw drive module, a rotary motor translation drive module 51, a belt translation drive module 51, a cylinder translation drive module 51, or a linear motor translation drive module 51.

[0051] In addition, a detection component connected to the drive motor 53 can be provided on the pressing member 40. After the pressing member 40 pushes the workpiece 60 to the positioning fixture 30, the detection component sends a signal, and the drive motor 53 starts again to drive the workpiece 60 to rotate.

[0052] In some optional embodiments, the rotary propulsion assembly 50 further includes a connector 54 and an elastic element 55. The drive motor 53 is drivenly connected to the connector 54, the pressing member 40 is movably mounted on the connector 54, and the elastic element 55 is disposed between the pressing member 40 and the connector 54. When the workpiece 60 is positioned, the translation drive module 51 drives the moving seat 52 to move, causing the pressing member 40 to move toward the positioning fixture 30, and causing the pressing member 40 to press the workpiece 60 against the positioning fixture 30, and causing the elastic element 55 to begin to generate elastic deformation. Then, the drive motor 53 drives the pressing member 40 to rotate, causing the pressing member 40 to drive the workpiece 60 to rotate, so that the workpiece 60 corresponds angularly with the limiting part 31. At this time, it is not necessary for the translation drive module 51 to continue to drive the moving seat 52 to move. Instead, the elastic force of the elastic element 55 drives the pressing member 40 to continue to move toward the positioning fixture 30, so that the circumferential limiting groove 62 of the workpiece 60 and the limiting part 31 of the positioning fixture 30 achieve circumferential limiting cooperation.

[0053] In some optional embodiments, an elastic friction pad 41 is provided on the side of the pressing member 40 facing the positioning space 21, thereby increasing the friction between the pressing member 40 and the workpiece 60. When the pressing member 40 rotates, it can smoothly drive the workpiece 60 to rotate synchronously, and the elasticity of the elastic friction pad 41 can also provide cushioning, thereby avoiding damage to the workpiece 60. In addition, in this embodiment, the detection component mentioned above can be a detection switch. The detection switch is set on the pressing member 40. When the pressing member 40 drives the workpiece 60 to press against the positioning fixture 30, the elastic friction pad 41 will be compressed, and the detection switch will come into contact with / approach the workpiece 60, causing the detection switch to be triggered. This causes the detection switch to send a signal to the drive motor 53, and the drive motor 53 drives the pressing member 40 to rotate.

[0054] The elastic friction pad 41 can be made of silicone pads, rubber pads, etc., and is not limited to this example.

[0055] The automatic positioning and feeding mechanism of the fully automatic roller printing machine described above can be applied to the fully automatic roller printing machine, which includes: the automatic positioning and feeding mechanism of the fully automatic roller printing machine described above.
