Description

Technical Field

[0001] The present invention belongs to the field of equipment for manufacturing pens, and relates to a refill assembly mechanism for a marker pen. Technical Background

[0002] The traditional production line for marker pens is very long. Each process corresponds to a work station and an action. Each work station is arranged side by side. The long production line occupies a large space, the structure is not compact and reasonable enough, and the production line cost is high. Summary of the Invention

[0003] According to the above problems, the present invention provides a novel refill assembly mechanism for a marker pen, which has the advantages of a compact structure, a short production line, and a small occupied space.

[0004] The object of the present invention is achieved as follows:

[0005] A refill assembly mechanism for a marker pen includes a base. A refill chute and a head shell chute are provided on the base. The outlet direction of the refill chute is correspondingly provided with a head shell installation position, so that the installation hole of the head shell is aligned with the refill chute. A refill cylinder for pushing the refill towards the head shell installation position is further provided on the refill chute. A head shell pushing cylinder is provided in front of the head shell chute, and a shell body installation position is provided behind the head shell chute. The head shell pushing cylinder pushes the head shell with the refill installed into the shell body.

[0006] A mechanical clamp and a mechanical clamp driving mechanism for driving the mechanical clamp to move are arranged above the base. The mechanical clamp driving mechanism includes a mechanical clamp clamping cylinder, a front and rear cylinder for moving the head shell from the head shell installation position towards the refill chute, and a transverse cylinder for moving the head shell with the refill installed above the head shell chute. A slot is opened above the head shell chute.

[0007] Through the above settings, the mechanical clamp clamps the head shell, and the front and rear cylinders move the head shell towards the refill chute. At the same time, the refill cylinder pushes the refill towards the head shell. The two cylinders move towards each other. While installing the refill into the head shell, the head shell is moved away from the head shell installation position, thus improving the installation efficiency. Then the transverse cylinder moves to drive the mechanical clamp to move and drive the head shell with the refill installed above the head shell chute. Then the mechanical clamp is loosened, and the head shell falls into the head shell chute. Finally, the head shell pushing cylinder pushes the head shell with the refill installed into the shell body. This device has a compact structure and a small occupied space.

[0008] The present utility model is further arranged as follows: A transverse groove is provided on the side of the refill chute. The extending end of the refill cylinder is connected with a connecting rod. The connecting rod includes a connecting section and a pushing section. The pushing section is arranged in the transverse groove and behind the refill.

[0009] The traditional refill cylinder is arranged behind the refill chute, which will increase the space. By arranging the horizontal chute on the side and the pushing section in the horizontal chute, the refill cylinder can be arranged on the side of the refill chute or below the refill chute, making more reasonable use of the space.

[0010] The present utility model is further arranged as follows: a refill inlet is further provided above the refill chute, and the refill inlet is connected with a refill feeding mechanism (the refill feeding mechanism can be a vibrating disk feeding, a robotic arm feeding or a manual feeding, etc.).

[0011] By feeding from above, it is also to make full use of the longitudinal space and reduce the lateral occupied space.

[0012] The present utility model is further arranged as follows: clamping gaps are provided on both sides of the head shell mounting position, and a pressing strip is provided above the head shell mounting position.

[0013] The head shell is stabilized by the pressing strip, and then the mechanical clamp clamps the head shell from the clamping gaps on both sides, and takes out the head shell from the head shell mounting position.

[0014] The present utility model is further arranged as follows: a positioning rod is provided at the outlet of the head shell mounting position, and a hinge seat is provided below the head shell mounting position, and the positioning rod is rotatably arranged on the hinge seat.

[0015] By rotatably arranging the positioning rod, when the mechanical clamp does not clamp the head shell and moves, the head shell is blocked and positioned by the positioning rod. When the mechanical clamp clamps the head shell and moves, the force given by the mechanical clamp drives the positioning rod to rotate, so that the head shell loses the restriction of the positioning rod and leaves the head shell mounting position.

[0016] The present utility model is further arranged as follows: the mechanical clamp driving mechanism includes a front and rear air cylinder and front and rear guide rails fixed on the frame, a front and rear sliding seat is fixed at the extending end of the front and rear air cylinder, and the front and rear sliding seat is slidably arranged on the front and rear guide rails.

[0017] The present utility model is further arranged as follows: a transverse guide rail and a transverse air cylinder are fixed on the front and rear sliding seat, a transverse sliding seat is connected to the extending end of the transverse air cylinder, the transverse sliding seat is slidably arranged on the transverse guide rail, and the transverse sliding seat is fixedly connected with the clamping air cylinder.

[0018] The present utility model is further arranged as follows: the mechanical clamp includes a head shell clamping part and a refill guiding part, and the refill guiding part is arranged in the direction of the head shell clamping part close to the refill chute.

[0019] The present utility model is further arranged as follows: the mechanical clamp includes two clamping arms, the refill guiding part is a guiding channel formed by two arc channels, the two arc channels are respectively arranged on the two clamping arms, and when the head shell clamping parts of the clamping arms clamp the head shell, the two arc channels are combined to form the guiding channel.

[0020] The present utility model is further configured such that: the guiding channel gradually becomes smaller from the pen refill chute towards the head shell mounting position.

[0021] Through the arrangement of the pen refill guiding portion and the gradually decreasing guiding channel, the pen refill can be accurately sent into the head shell, making the process more stable and the finished product rate higher.

[0022] The prominent and beneficial technical effects of the present invention compared with the prior art are as follows: This device integrates the two processes of loading the pen refill into the head shell and then loading the head shell with the pen refill into the shell body on a single base, making the entire production line shorter and occupying less space.

Detailed implementation mode

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0033] A pen core assembly mechanism for a marker pen, comprising a base 1, on which a pen core chute 4 and a head shell chute 5 are provided. The outlet direction of the pen core chute 4 is correspondingly provided with a head shell installation position 6, so that the installation hole of the head shell 3 is aligned with the pen core chute 4. A pen core cylinder 7 for pushing the pen core 2 towards the head shell installation position 6 is further provided on the pen core chute 4. A head shell pushing cylinder 8 is provided in front of the head shell chute 5, and a shell body installation position 9 is provided behind the head shell chute 5. The head shell pushing cylinder 8 pushes the head shell with the pen core installed into the shell body (not shown);

[0034] A mechanical clamp 10 is provided above the base 1, and a mechanical clamp driving mechanism for driving the mechanical clamp to move. The mechanical clamp driving mechanism includes a mechanical clamp clamping cylinder 11, a front and rear cylinder 12 for moving the head shell 3 from the head shell installation position 6 towards the pen core chute 4, and a transverse movement cylinder 13 for moving the head shell with the pen core installed above the head shell chute 5; The head shell chute 5 is provided with a slot above.

[0035] With the above settings, the mechanical clamp 10 clamps the head shell 3, and the front and rear cylinder 12 moves the head shell 3 towards the pen core chute 4. At the same time, the pen core cylinder 7 pushes the pen core 2 towards the head shell 3. The two cylinders move towards each other. While installing the pen core 2 into the head shell 3, the head shell 3 is moved away from the head shell installation position 6, thus improving the installation efficiency; Then the transverse movement cylinder 13 moves to drive the mechanical clamp 10 to move and drive the head shell with the pen core installed above the head shell chute 5. Then the mechanical clamp is released, and the head shell 3 falls into the head shell chute 5. Finally, the head shell pushing cylinder 8 pushes the head shell with the pen core installed into the shell body. The device has a compact structure and occupies a small space.

[0036] A transverse groove 41 is provided on the side of the pen core chute 4. The extending end of the pen core cylinder 7 is connected with a connecting rod, and the connecting rod includes a connecting section 71 and a pushing section 72. The pushing section 72 is arranged in the transverse groove 41 and behind the pen core 2. The traditional pen core cylinder is arranged behind the pen core chute, which will increase the space. By arranging the transverse groove 41 on the side and the pushing section 72 in the transverse groove 41, the pen core cylinder 7 can be arranged on the side of the pen core chute 4 or below the pen core chute 4, which can make more reasonable use of the space.

[0037] Above the pen refill chute 4, there is also a pen refill inlet 42, which is connected to a pen refill feeding mechanism. The pen refill feeding mechanism can be a vibrating disk feeder, a robotic arm feeder, or manual feeding, etc. By feeding from above, it is also to make full use of the longitudinal space and reduce the lateral occupied space.

[0038] On both sides of the head shell mounting position 6, there are clamping gaps 61, and above the head shell mounting position 6, there is a pressing strip 62. The head shell is stabilized by the pressing strip, and then the mechanical clamp clamps the head shell from the clamping gaps on both sides to take out the head shell from the head shell mounting position.

[0039] At the exit of the head shell mounting position, there is a positioning rod 63, and below the head shell mounting position, there is a hinge seat 64. The positioning rod 63 is rotatably arranged on the hinge seat 64. Through the rotatable arrangement of the positioning rod, when the mechanical clamp does not clamp the head shell and moves, the head shell is blocked and positioned by the positioning rod. When the mechanical clamp clamps the head shell and moves, the force applied by the mechanical clamp drives the positioning rod to rotate, so that the head shell loses the restriction of the positioning rod and leaves the head shell mounting position.

[0040] The mechanical clamp driving mechanism includes a front and rear air cylinder 12 and front and rear guide rails 121 fixed on the frame. The extending end of the front and rear air cylinder 12 is fixed with a front and rear sliding seat 122, and the front and rear sliding seat 122 is slidably arranged on the front and rear guide rails 121. A transverse guide rail 131 and a transverse air cylinder 13 are fixed on the front and rear sliding seat 122. The extending end of the transverse air cylinder 13 is connected with a transverse sliding seat 132, and the transverse sliding seat 132 is slidably arranged on the transverse guide rail 131. The transverse sliding seat 132 is fixedly connected with the clamping air cylinder 11.

[0041] The mechanical clamp 10 includes a head shell clamping part 14 and a pen refill guiding part 15. The pen refill guiding part 15 is arranged in the direction of the pen refill chute 4 close to the head shell clamping part 14.

[0042] The mechanical clamp 10 includes two clamping arms 101. The pen refill guiding part 15 is a guiding channel 16, which is formed by two arc channels. The two arc channels are respectively arranged on the two clamping arms 101. When the head shell clamping parts of the clamping arms clamp the head shell, the two arc channels are combined to form the guiding channel 16. The guiding channel 16 gradually becomes smaller from the pen refill chute 4 to the head shell mounting position 6. Through the setting of the pen refill guiding part and the gradually decreasing guiding channel, the pen refill can be accurately sent into the head shell, making the process more stable and the yield higher.

[0043] The present invention has the characteristics of a compact structure, a short production line, and a small occupied space.

[0044] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
