[0002] A push-button pencil is a special automatic pencil, and its characteristic lies in pushing the lead out through a pushing operation. The lead-out mechanism of this pencil is designed such that each time it is pushed, the lead will extend a certain length, thus achieving continuous writing without manually rotating or pushing the lead. When producing push-button pencils, the lead needs to be assembled into the push-button pencil.

[0003] In an assembly production device for push-button pencils with the application publication number of "CN109501489A", the lead combination machine of this automatic pencil can efficiently and quickly complete the combination and assembly of the lead, improving production efficiency. However, for this assembly production device of push-button pencils, due to the different models of push-button pencils, it can only limit the push-button pencils of the limited models during the assembly of push-button pencils, thus increasing the working limitations. At the same time, for this assembly production device of push-button pencils, after the assembly of push-button pencils, the unqualified push-button pencils need to be found by workers subsequently, thus increasing the labor force of workers. Summary of the Invention

[0004] The utility model aims to solve the above problems existing in the prior art, and provides an assembly production device for push-button pencils, achieving the purpose of reducing working limitations and reducing the labor force of workers.

[0005] The technical solution adopted by the utility model to solve its technical problems: This assembly production device for push-button pencils includes a frame. A marking mechanism is installed on the outer wall of the lower side of the frame. The inner wall of the frame is slidably connected to a plate body. A limiting mechanism is installed at the upper end of the plate body. The frame is fixedly connected to a first servo motor through a bracket. The output shaft of the first servo motor is connected to a threaded rod through a speed reducer. Both sides of the threaded rod are rotatably connected to the frame through bearings. The outer wall of the threaded rod is threadedly connected to the plate body.

[0006] For further improvement, the limiting mechanism includes a first housing. The lower end of the first housing is fixedly connected to the plate body. A rod body is fixedly connected to the inner wall of the first housing. The outer wall of the rod body is slidably connected to a first vertical plate and a second vertical plate respectively. The outer walls of the first vertical plate and the second vertical plate are slidably connected to the first housing. The inner sides of the first vertical plate and the second vertical plate are both in contact with the push-button pencil.

[0007] For further improvement, the outer wall of the rod body is sleeved with the first spring. The two ends of the first spring are respectively fixedly connected to the first vertical plate and the second vertical plate. The outer walls of the first vertical plate and the second vertical plate are both in contact with the block. The inner wall of the block is fixedly connected to the handle. The end of the handle is rotationally connected to the first housing through a bearing.

[0008] For further improvement, the marking mechanism includes a second housing. The lower end of the second housing is fixedly connected to the frame. The second housing is fixedly connected to the second servo motor through a bracket. The output shaft of the second servo motor is connected to the rotating shaft of the connecting rod through a speed reducer. The connecting rod is rotationally connected to the second housing through a rotating shaft. The outer wall of the connecting rod is slidably connected to the inclined block. The lower end of the inclined block is slidably connected to the second housing. The inclined block is in contact with the vertical block through a roller. The outer wall of the vertical block is slidably connected to the second housing.

[0009] For further improvement, a second spring is provided on the left side of the upper end of the vertical block. The two ends of the second spring are respectively fixedly connected to the vertical block and the second housing. The right end of the vertical block is threadedly connected to a bolt.

[0011] The beneficial effect of the present utility model is as follows: In the present utility model, through the cooperation of the limiting mechanism and the plate body, the handle drives the first vertical plate and the second vertical plate to move. When the distance between the first vertical plate and the second vertical plate moves to be greater than the push-type pencil to be assembled, stop rotating the handle. Then move the push-type pencil to be assembled between the first vertical plate and the second vertical plate. After the push-type pencil moves between the first vertical plate and the second vertical plate, reverse the handle. The first spring rebounds and the first vertical plate and the second vertical plate are reset according to the above method. During the reset process of the first vertical plate and the second vertical plate, they come into contact with the push-type pencil and thus limit it. After the push-type pencil is limited, stop rotating the handle. The push-type pencil is limited in the above way, and the distance between the first vertical plate and the second vertical plate can be adjusted to limit push-type pencils of different models, thereby reducing the working limitations.

[0012] Through the cooperation of the marking mechanism and the frame, the second servo motor drives the connecting rod to swing counterclockwise. The connecting rod drives the inclined block to move leftward through the chute, and then the roller moves upward along with the slope of the inclined block. At this time, the second spring is compressed to form an elastic force. The roller drives the vertical block to move and then drives the marking pen to move upward. In the above way, the unqualified push-type pencils for assembly are marked so as to distinguish them in subsequent work, thereby reducing the labor of workers. Description of the Drawings

[0027] Working principle:

[0028] When assembling a push-type pencil, the worker turns the handle 205. The handle 205 drives the first vertical plate 203 and the second vertical plate 207 to move (the moving directions of the first vertical plate 203 and the second vertical plate 207 are opposite). At this time, the first spring 204 is stretched. When the distance between the first vertical plate 203 and the second vertical plate 207 moves to be greater than the push-type pencil to be assembled, stop turning the handle 205. Then move the push-type pencil 11 to be assembled between the first vertical plate 203 and the second vertical plate 207. After the push-type pencil 11 moves between the first vertical plate 203 and the second vertical plate 207, reverse the handle 205. The first spring 204 rebounds and the first vertical plate 203 and the second vertical plate 207 are reset in the above manner. During the reset process, the first vertical plate 203 and the second vertical plate 207 come into contact with the push-type pencil 11 and limit it. When the push-type pencil 11 is limited, stop turning the handle 205. The push-type pencil is limited on the first housing 201 in the above manner;

[0029] After all the push-type pencils are fully positioned on the first housing 201, the external power supply of the camera 5 is connected and started, and the camera 5 starts to work. At this time, the push-type pencil on the right side of the first housing 201 is aligned with the lead storage tube 4. The lead storage tube 4 puts the pencil lead into the pen tube in the push-type pencil and then assembles it. The way the lead storage tube 4 assembles the pencil lead into the push-type pencil is the same as that in the publication number "CN109501489A". After the first push-type pencil on the right is assembled, the external power supply of the first servo motor 6 is connected and started. The first motor 6 drives the threaded rod 7 to rotate slowly. The threaded rod 7 drives the plate 8 to move and then drives the first housing 201 to move slowly to the right. When the second push-type pencil on the right moves below the lead storage tube 4, the first servo motor 6 is turned off. Then the lead storage tube 4 continues to assemble the second push-type pencil. At this time, the first assembled push-type pencil is under the camera 5, and the camera 5 detects the first assembled push-type pencil;

[0030] If the assembly of the pencil lead in the push-type pencil is unqualified, the external power supply of the second servo motor 302 is connected and started. The second servo motor 302 drives the connecting rod 303 to swing counterclockwise (the degree that the connecting rod 303 can swing counterclockwise is 80 degrees). The connecting rod 303 drives the inclined block 304 to move leftward through the chute, and then the roller 305 moves upward along with the slope of the inclined block 304. At this time, the second spring 307 is compressed to form an elastic force. The roller 305 drives the vertical block 306 to move and then drives the marker pen upward (the marker pen 9 can be removed from the vertical block 306 for replacement by loosening the bolt 10). When the marker pen 9 moves, the tip of the marker pen 9 contacts the push-type pencil and then marks the push-type pencil. The unqualified push-type pencils are marked in the above way. After the unqualified push-type pencils are marked, the second servo motor 302 reverses according to the above way. The second spring 307 releases the elastic force and then drives the marker pen 9 to reset. After the position of the marker pen 9 is reset, the second servo motor 302 is turned off;

[0031] After all the push-type pencils on the first housing 201 are assembled according to the above way, the first servo motor 6 continues to rotate to drive the first housing 201 out of the frame 1 and move it to the right side of the frame 1. When the first housing 201 moves to the right side of the frame 1, the first servo motor 6 is turned off. Then, according to the above way, the limit on the push-type pencil is cancelled. Then the worker uses an external box to place the qualified push-type pencils and unqualified push-type pencils separately. The marked unqualified push-type pencils are easy to distinguish when collecting the push-type pencils. They are put together uniformly, which is convenient for later reassembly. The assembly work of the push-type pencils is completed through the above way.
