Automatic marking mechanism to prevent pen from drying out

Abstract

This utility model relates to the field of automated processing technology, specifically an automatic marking mechanism to prevent ink drying. The lifting assembly of this utility model drives the pen body to move up and down, causing the drive block to move up and down, resulting in the synchronous rotation of two rotating blocks that expose the pen tip. Simultaneously, it pushes the pen body and the pusher assembly to extend between the two rotating blocks for product marking. It employs a two-stage linkage pen-out structure. The first stage opens the cover of the rotating blocks, while the second stage increases the length of the pen tip extension to prevent collisions between the rotating blocks on the pen cover assembly and parts on the product being marked. The two rotating blocks provide a sealed protection for the pen tip, preventing it from drying out due to air exposure, ensuring smooth ink flow when the pen is reused after a period of inactivity.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1-3 As shown, an automatic marking mechanism to prevent pen drying includes:

[0027] Frame 1, on which an installation station is provided;

[0028] Lifting component 2 is installed at the installation station. Lifting component 2 is driven to drive pen body 5 and is used to drive pen body 5 to perform lifting and lowering movements.

[0029] A pusher assembly 4 is disposed on the pen body 5, and the pusher assembly 4 is used to fix and guide the pen body 5.

[0030] The pen-covering assembly 7 is mounted on the frame 1. The pen-covering assembly 7 includes a fixed frame and a drive block 6. Rotating blocks 74 are provided on both sides of the fixed frame. The lifting assembly 2 is driven to the drive block 6. The drive block 6 is driven to the two rotating blocks 74. The lifting assembly 2 is used to drive the drive block 6 to move up and down so that the two rotating blocks 74 rotate synchronously to cover the pen tip.

[0031] The lifting component 2 of this utility model drives the pen body 5 to move up and down, which in turn drives the drive block 6 to move up and down, causing the two rotating blocks 74 to rotate synchronously and expose the pen tip. At the same time, it also pushes the pen body 5 and the pusher component 4 to extend between the two rotating blocks 74 to mark the product. It adopts a two-stage linkage pen-out structure. The first stage drives the opening of the cover of the rotating block 74. The second stage can increase the length of the pen tip of the MARK pen (pen body 5) to prevent the rotating block 74 on the pen cover component 7 from colliding with the parts on the product being marked. The two rotating blocks 74 can seal and protect the pen tip of the MARK pen (pen body 5), thereby preventing the pen tip from drying out due to exposure to air, so that the ink flow and marking are smooth when the pen is restarted after being stopped for a period of time.

[0032] In one embodiment of this utility model, the lifting assembly 2 includes a lifting plate 21, a lifting guide rail 22 is provided on the installation station, the lifting plate 21 is slidably mounted on the lifting guide rail 22, a lifting cylinder 23 is provided on the frame 1, the lifting cylinder 23 is drivenly connected to the lifting plate 21, a pusher 3 is provided on the lifting plate 21, the pusher 3 is connected to the top of the pen body 5, and the pusher assembly 4 and the drive block 6 are slidably mounted on the lifting plate 21.

[0033] Specifically, when a pen is needed, the lifting cylinder 23 drives the lifting plate 21 to move downwards, and the lifting plate 21 drives the driving block 6 to drive the rotating block 74 to open the covering chamber. At the same time, the lifting cylinder 23 pushes the pen body 5 to release the pen. This linkage design can realize the automatic opening and closing of the pen covering component 7.

[0034] In one embodiment of the present invention, the pushing component 4 includes two clamping blocks 41, and the clamping blocks 41 are provided with clamping grooves 42 that match the pen body 5. The clamping grooves 42 on the two clamping blocks 41 clamp the pen body 5, and one of the two clamping blocks 41 slides on the lifting plate 21.

[0035] Specifically, the clamping grooves 42 on the two clamping blocks 41 clamp the pen body 5. One of the clamping blocks 41 slides on the lifting plate 21. When replacing the pen body 5, it is only necessary to loosen the other clamping block 41, which is convenient for maintenance.

[0036] In one embodiment of the present invention, the pusher 3 includes a bracket 31, which is disposed on the lifting plate 21. A pusher rod is disposed on the bracket 31, and a pusher plate 33 is disposed at the free end of the pusher rod. The pusher plate 33 abuts against the top of the pen body 5.

[0037] Specifically, the lifting cylinder 23 continues to drive the lifting plate 21 to move downward, pushing the push rod on the bracket 31 to push the pen body 5 on the push plate 33 to move downward until the clamping block 41 abuts against the drive spring 8 and compresses it, causing the pen body 5 to move downward until the pen tip extends out between the rotating block 74 to make a mark. This can increase the length of the pen tip extension of the MARK pen (pen body 5) to prevent the pen wrapping mechanism from colliding with the parts on the product being marked.

[0038] In one embodiment of this utility model, the push rod includes a guide rod 34, a linear bearing 32 is provided on the bracket 31, the guide rod 34 passes through the linear bearing 32, and a push spring 35 is sleeved on the guide rod 34. One end of the push spring 35 abuts against the push plate 33, and the other end abuts against the bracket 31. A limit block 36 is provided at the free end of the guide rod 34 so that the guide rod 34 cannot detach from the linear bearing 32.

[0039] Specifically, the push spring 35 supports the pen body 5, causing the drive block 6, which slides on the lifting plate 21, to move downward. At the same time, when the pen body 5 extends too far, the push spring 35 is compressed to buffer the movement, preventing the MARK pen from being damaged and improving the marking effect.

[0040] In one embodiment of the present invention, the drive block 6 is provided with a guide groove 61, the rotating block 74 is provided with a guide shaft, and a rotating wheel is rotated on the guide shaft. The rotating wheel is disposed in the guide groove 61. The lifting component 2 drives the drive block 6 to move up and down, so that the two rotating wheels on the two rotating blocks 74 move relative to each other in the guide groove 61 to achieve synchronous rotation of the two rotating blocks 74.

[0041] Specifically, the drive block 6, which slides on the lifting plate 21, moves downward, causing the two rotating wheels on the two rotating blocks 74 to move along the guide groove 61 towards both ends of the guide groove 61. The rotating blocks 74 rotate along the bearing seat 73, achieving synchronous rotation of the two rotating blocks 74, which opens the covering chamber and exposes the pen tip of the pen body 5, forming a follower structure and achieving synchronous movement of the two rotating blocks 74. When the two rotating blocks 74 fully open the covering chamber, the two rotating wheels on the two rotating blocks 74 are located at both ends of the guide groove 61, so that the drive block 6 can only move with the lifting plate 21 and cannot continue to move downward, thereby limiting the opening and closing angle of the rotating blocks 74 and also making way for the second pen tip to extend, avoiding interference.

[0042] In one embodiment of the present invention, the fixing frame includes a connecting block 71, fixing blocks 72 are provided on both sides of the connecting block 71, a bearing seat 73 is provided on the fixing block 72, and the rotating block 74 is provided on the bearing seat 73.

[0043] Specifically, the two rotating wheels on the two rotating blocks 74 move along the guide groove 61 towards the two ends of the guide groove 61 respectively. At the same time, the rotating blocks 74 rotate along the bearing seat 73, so that the synchronous rotation of the two rotating blocks 74 opens the covering chamber and exposes the pen tip of the pen body 5. The bearing seat 73 can make the rotating blocks 74 open and close more smoothly, ensuring the covering effect of the pen tip.

[0044] In one embodiment of the present invention, a movable guide rail 81 is provided on the lifting plate 21, and a first slider 82 and a second slider 83 are provided on the movable guide rail 81. The first slider 82 is connected to the driving block 6, and the pushing component 4 is provided on the second slider 83. The pushing component 4 and the driving block 6 move relative to each other along the movable guide rail 81.

[0045] Specifically, as the pusher assembly 4 and the drive block 6 move relative to each other along the moving guide rail 81, the free end of the drive spring 8 on the drive block 6 abuts against the pusher assembly 4, and the pusher spring 35 supports the pen body 5, causing the drive block 6, which slides on the lifting plate 21, to move downward, facilitating the opening and closing of the rotating block 74. The two move on the same moving guide rail 81, which can ensure the consistency of the movement direction, ensure the synchronous opening and closing of the two rotating blocks 74, and improve the accuracy of use.

[0046] In one embodiment of this utility model, the drive block 6 is provided with a mounting hole, a fixed shaft is provided in the mounting hole, a drive spring 8 is sleeved on the fixed shaft, and the free end of the drive spring 8 abuts against the pusher assembly 4.

[0047] Specifically, the free end of the drive spring 8 abuts against the pusher assembly 4, so that the drive spring 8 is located between the drive block 6 and the clamping block 41. As the lifting cylinder 23 continues to drive the lifting plate 21 to move downward, the clamping block 41 abuts against the drive spring 8 and compresses it, causing the pen body 5 to move downward until the pen tip extends out of the rotating block 74 for marking, thus playing the role of supporting the two and their relative movement.

[0048] In one embodiment of the present invention, the rotating block 74 is provided with a slot 75 that matches the tip of the pen body 5, and the slots 75 on the two rotating blocks 74 are combined to form a covering chamber, in which the tip of the pen body 5 is wrapped.

[0049] Specifically, the tip of the pen body 5 is enclosed in the encapsulation chamber formed by the two slots 75, which seals and protects the tip of the MARK pen (pen body 5), thereby preventing the tip from drying out due to exposure to air, and ensuring smooth ink flow when the pen is restarted after being stopped for a period of time.

[0050] Usage process

[0051] In the initial state, the tip of the pen body 5 is wrapped in the enclosing cavity formed by the two slots 75. The clamping slots 42 on the two clamping blocks 41 clamp the pen body 5. At the same time, the push spring 35 and the drive spring 8 are in normal state. When the pen is needed, the lifting cylinder 23 drives the lifting plate 21 to move downward. The two rotating wheels on the two rotating blocks 74 are in the guide groove 61. The drive block 6 sliding on the lifting plate 21 has an upward tendency. Since the push assembly 4 and the drive block 6 move relative to each other along the moving guide rail 81, the free end of the drive spring 8 on the drive block 6 abuts against the push assembly 4, and the push spring 35 supports the pen body 5, so that the drive block 6 sliding on the lifting plate 21 moves downward, so that the two rotating wheels on the two rotating blocks 74 move along the guide groove 61 towards the two ends of the guide groove 61 respectively. At the same time, the rotating blocks 74 rotate along the bearing seat 73, so that the synchronous rotation of the two rotating blocks 74 opens the enclosing cavity and exposes the tip of the pen body 5.

[0052] When the two rotating blocks 74 fully open the covering chamber, the two rotating wheels on the two rotating blocks 74 are located at the two ends of the guide groove 61, so that the drive block 6 can only move with the lifting plate 21 and cannot continue to move downward. The lifting cylinder 23 continues to drive the lifting plate 21 to move downward, pushing the push spring 35 on the bracket 31 to push the pen body 5 on the push plate 33 to move downward. One of the two clamping blocks 41 slides on the moving guide rail 81, thereby driving the push assembly 4 and the pen body 5 to move downward synchronously until the clamping block 41 abuts against the drive spring 8 and... The pen body 5 is compressed and moves downward until the pen tip extends out between the rotating block 74 for marking. The lifting plate 21 drives the driving block 6 to drive the rotating block 74 to open the covering chamber. At the same time, the lifting cylinder 23 pushes the pen body 5 to extend the pen. The linkage design can automatically open and close the pen covering assembly 7. This utility model adopts a two-stage pen extension structure. The first stage drives the rotating block 74 to open the covering chamber. The second stage can increase the extension length of the pen tip of the MARK pen (pen body 5) to prevent the pen covering assembly 7 from colliding with the parts on the product being marked.
