Description

Technical Field

[0001] This utility model relates to the technical field of pen product processing equipment, specifically to a marker pen assembly device. Background Technology

[0002] Marker pens, as a brightly colored and easy-to-use drawing tool, have been widely welcomed since their invention. Their unique ink formula results in smooth strokes and vibrant colors, making them a common sight in both professional design and everyday life. This article will begin with the basic definition and characteristics of marker pens, then explore their various uses in drawing, design, office work, study, and daily life, and share some usage tips and maintenance methods.

[0003] Existing marker pens mainly consist of multiple components such as the barrel, middle section, core, nib, and cap. In the current assembly industry, they are generally assembled manually in stages, requiring multiple transfers. Manual assembly is inefficient and cannot guarantee the quality of assembly. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an assembly device for marker pens.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A marker assembly device includes a machine base, on which a conveying structure for conveying the marker barrel is provided. The input end of the conveying structure is provided with a marker barrel feeding structure, and the machine base is provided with a middle section cotton core mounting structure, a flat pen tip mounting structure, and a pen cap mounting structure sequentially arranged along the marker barrel conveying direction.

[0007] The middle section cotton core installation structure includes a first feeding module for feeding the middle section, a second feeding module for feeding the cotton core, and a joining assembly for joining the middle section and the cotton core. The joining assembly includes a joining plate for receiving and transferring the middle section and the cotton core, a rotating unit for driving the joining plate to rotate, a joining module for joining the middle section and the cotton core during the rotation of the joining plate, and a pushing module for joining the middle section and the cotton core to the pen barrel.

[0008] The flat pen tip mounting structure includes a third feeding module for feeding the flat pen tip, a first receiving plate for receiving the flat pen tip, and a first push rod slidably disposed on the first receiving plate. The first push rod drives the flat pen tip to move toward the pen shaft so that the flat pen tip is mounted on the middle section.

[0009] The pen cap mounting structure includes a fourth feeding module for feeding pen caps, a second receiving plate for receiving pen caps, and a second push rod slidably disposed on the second receiving plate. The second push rod drives the pen cap to move toward the pen barrel so that the pen cap is mounted on the pen barrel.

[0010] Preferably, the machine base is provided with a joining seat, and the joining plate is mounted on the joining seat. The joining plate has several joining channels for joining the middle section and the cotton core. The joining seat has a discharge channel. The joining module includes a joining rod and a joining unit that drives the joining rod to move. The joining rod is arranged opposite to the joining channel. The joining rod pushes the cotton core so that the cotton core is inserted into the middle section. The pushing module includes a discharge rod that is slidably arranged on the discharge channel. The discharge rod pushes the middle section with the inserted cotton core toward the pen barrel and forces the middle section to be inserted into the pen barrel. Through the above improvements, in the assembly process of the marker pen, the first feeding module and the second feeding module input the cotton core and the middle section into the joining channel, and join the middle section and the cotton core through the joining rod. After the middle section and the cotton core are joined, they fall into the discharge channel and join with the pen barrel under the action of the discharge rod. This realizes the automatic assembly of some components of the marker pen and greatly improves the production efficiency.

[0011] Preferably, the joining channel has a feeding position opposite to the output ends of the first feeding module and the second feeding module, a joining position opposite to the joining rod, and a discharging position opposite to the discharging channel. The joining seat is provided with a limiting stop, which is arranged along the outer contour of the joining plate. The limiting stop is set between the feeding position and the discharging position to prevent the cotton core and the component from leaving the joining channel. Through the above improvements, during the rotation of the joining plate, the cotton core and the middle section are first fed at the feeding position, then rotated to the joining position for joining, and finally rotated to the discharging position so that the joined middle section and the cotton core fall into the discharging channel. The limiting stop is used to limit the cotton core and the middle section, preventing the cotton core and the middle section from leaving the joining plate during the rotation.

[0012] Preferably, the joining seat is provided with a positioning component, which includes a positioning block and a positioning cylinder for driving the positioning block to move. When the middle section and the cotton core are joined, the positioning block abuts against the middle section. Through the above improvements, when the joining disc rotates to the joining position, the positioning cylinder will drive the positioning block to move and abut against the middle section, avoiding the middle section from shifting during the joining process and improving the joining quality of the middle section and the cotton core.

[0013] Preferably, the discharge rod is mounted on the sliding block, and a detection rod is inserted on the sliding block opposite to the pen barrel. The detection rod and the discharge rod are spaced apart. An elastic element is sleeved on the detection rod, with one end of the elastic element abutting the detection rod and the other end abutting the sliding block, so that the detection rod always has a tendency to move towards the pen barrel. A sensing ring is provided at the end of the detection rod, and a position sensor for the sensing ring is provided on the sliding block. With the above improvements, the conveying structure will convey the pen barrel that has been joined with the middle section and the cotton core, so that it is positioned opposite the detection rod. The detection rod abuts against the middle section, and the sensing ring at the end of the detection rod cooperates with the position sensor to determine whether the middle section and the cotton core are installed in place, thereby further improving the assembly quality.

[0014] Preferably, a repressing rod is also inserted on the sliding block, and the repressing rod and the detection rod are arranged at intervals. With the above improvement, the pen barrel after being detected by the detection rod is set opposite to the repressing rod under the conveying structure. The repressing rod will squeeze the middle section again, thereby ensuring the joining quality of the pen barrel and the middle section.

[0015] Preferably, the machine tool is also equipped with a defective product rejection component. The defective product rejection component includes a mounting bracket disposed on the side of the conveying structure and a rejection cylinder fixed on the mounting bracket. The rejection cylinder is oriented towards the conveying structure. Through the above improvements, the defective product rejection component is disposed at the rear of the detection rod. When a defective product is detected, the rejection cylinder will push the corresponding pen rod out of the conveying structure, thereby ensuring the quality of product assembly.

[0016] Preferably, the conveying structure includes a first conveying plate fixedly mounted on the machine base, a second conveying plate movably mounted on the machine base, and a drive rod assembly for driving the second conveying plate to move up, down, left, and right. The first conveying plate has a first receiving groove for receiving the pen, and the second conveying plate has a second receiving groove for receiving the pen. The first and second receiving grooves are staggered. The drive rod assembly includes a drive rod, an eccentric drive wheel sleeved on the drive rod, a connecting rod connected to the bottom of the second conveying plate, and a drive unit for driving the drive rod to rotate. The eccentric drive wheel drives the connecting rod to rotate, thereby driving the second conveying plate to swing and transfer the pen from the first receiving groove to the next first receiving groove. Through this improvement, the eccentric drive wheel drives the connecting rod to rotate, causing the second conveying plate to move. The second conveying plate moves upward and forward, causing the pen in the first receiving groove to fall into the second receiving groove. As the second conveying plate moves downward and backward, the pen in the second receiving groove falls into the next second receiving groove, thus realizing the conveying of the pen.

[0017] Preferably, the machine base is further provided with a pressure rod assembly, which includes a pressure bracket and a plurality of pressure rods disposed on the pressure bracket. The drive rod is fitted with a lifting eccentric wheel that drives the pressure bracket to move up and down. With the above improvements, the pressure bracket rises and falls with the operation of the conveying structure, and the pressure rods correspond to some assembly positions, which will press the pen barrel during the assembly process, further improving the assembly quality.

[0018] Preferably, the pen barrel feeding structure includes a feeding tray and a feeding channel, and a pushing cylinder is provided on the machine base. A pushing plate is connected to the actuating end of the pushing cylinder. When the pushing cylinder is actuated, the pushing plate pushes the pen barrel in the feeding channel into the conveying structure. Through the above improvements, during the feeding process, the feeding tray conveys the pen barrel to the machine base through the feeding channel, and the unloading plate pushes the pen barrel at the bottom of the feeding channel into the conveying structure, thus realizing automatic pen barrel feeding.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] By setting a conveying structure on the machine base, and a pen barrel feeding structure at the input end of the conveying structure, and by sequentially setting a middle section cotton core mounting structure, a flat pen tip mounting structure, and a pen cap mounting structure along the pen barrel conveying direction on the machine base, the pen barrel is automatically fed under the action of the pen barrel feeding structure and conveyed by the conveying structure. When the pen barrel moves to the middle section cotton core mounting structure, the first feeding module assembly and the second feeding module assembly input the middle section and cotton core into the joining plate, and the joining component joins the middle section and cotton core. Finally, the pushing module pushes the middle section and cotton core together. The pen is attached to the pen barrel, and then the conveying structure transports the pen barrel to the flat pen tip mounting structure. The third feeding module places the flat pen tip onto the first receiving plate and installs the flat pen tip onto the middle section through the first top feeding rod. Finally, the conveying structure transports the pen barrel to the pen cap mounting structure, where the fourth feeding module places the flat pen tip onto the second receiving plate and installs the flat pen tip onto the pen barrel through the second top feeding rod. The assembled marker pen is then discharged by the conveying structure. This process realizes the automatic feeding and assembly of multiple components of the marker pen, which not only greatly improves the assembly efficiency but also ensures the assembly quality.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0031] like Figure 1-7 As shown, a marker pen assembly device includes a machine base 1, a conveying structure 2 for conveying the pen barrel on the machine base 1, a pen barrel feeding structure 3 at the input end of the conveying structure 2, and a middle section cotton core mounting structure 4, a flat pen tip mounting structure 5, and a pen cap mounting structure 6 arranged sequentially on the machine base 1 along the pen barrel conveying direction.

[0032] Specifically, the middle section cotton core mounting structure 4 includes a first feeding module 1.1 for feeding the middle section, a second feeding module 1.2 for feeding the cotton core, and a joining assembly 1.3 for joining the middle section and the cotton core. The joining assembly 1.3 includes a joining plate 1.4 for receiving and transferring the middle section and the cotton core, a rotating unit 1.7 for driving the joining plate 1.4 to rotate, a joining module 1.5 for joining the middle section and the cotton core during the rotation of the joining plate 1.4, and a pushing module 1.6 for joining the middle section and the cotton core to the pen barrel.

[0033] Furthermore, the flat pen tip mounting structure 5 includes a third feeding module 2.1 for feeding the flat pen tip, a first receiving plate 2.2 for receiving the flat pen tip, and a first push rod 2.3 slidably disposed on the first receiving plate 2.2. The first push rod 2.3 drives the flat pen tip to move toward the pen shaft so that the flat pen tip is mounted on the middle section.

[0034] The pen cap mounting structure 6 includes a fourth feeding module 2.4 for feeding pen caps, a second receiving plate 2.5 for receiving pen caps, and a second push rod 2.6 slidably disposed on the second receiving plate 2.5. The second push rod 2.6 drives the pen cap to move toward the pen barrel so that the pen cap is mounted on the pen barrel.

[0035] In the entire marker assembly process, the pen barrel is first automatically fed by the pen barrel feeding structure 3 and then transported by the conveying structure 2. When the pen barrel moves to the middle section cotton core mounting structure 4, the first feeding module 1.1 and the second feeding module 1.2 input the middle section and cotton core into the joining plate 1.4, and the middle section and cotton core are joined by the joining component 1.3. Then, the middle section and cotton core are joined to the pen barrel by the pushing module 1.6. Subsequently, the conveying structure 2 transports the pen barrel to the flat pen tip mounting structure 5, and the third feeding module 1.4... The material module 2.1 places the flat pen tip onto the first receiving plate 2.2 and installs it onto the middle section via the first top-feeding rod 2.3. Finally, the conveying structure 2 conveys the pen barrel to the pen cap mounting structure 6. The fourth feeding module 2.4 places the flat pen tip onto the second receiving plate 2.5 and installs it onto the pen barrel via the second top-feeding rod 2.6. The assembled marker pen is then discharged by the conveying structure 2. This process realizes automatic feeding and assembly of multiple components of the marker pen, which not only greatly improves assembly efficiency but also ensures assembly quality.

[0036] like Figures 1 to 5 As shown, a further explanation of the connection of the middle section cotton core installation structure 4 in this embodiment is provided. The machine base 1 is provided with a connection seat 3.1, and the connection plate 1.4 is mounted on the connection seat 3.1. The connection plate 1.4 forms a plurality of connection channels 3.2 for connecting the middle section and the cotton core. The connection seat 3.1 forms a discharge channel 3.3. The connection module 1.5 includes a connection rod 3.4 and a connection unit 3.5 for driving the connection rod 3.4 to move. The connection rod 3.4 is arranged opposite to the connection channel 3.2. The connection rod 3.4 pushes the cotton core so that the cotton core is inserted into the middle section. The push module 1.6 includes a discharge rod 3.7 slidably arranged on the discharge channel 3.3. The discharge rod 3.7 pushes the middle section with the inserted cotton core towards the pen barrel and forces the middle section to be inserted into the pen barrel.

[0037] During the assembly process of the marker pen, the first feeding module 1.1 and the second feeding module 1.2 first feed the cotton core and the middle section into the joining channel 3.2. When the joining plate 1.4 rotates to a certain position, the joining rod 3.4 is positioned opposite to the joining channel 3.2, and the middle section and the cotton core are joined by the joining rod 3.4. After the joining is completed, the middle section and the cotton core will fall into the discharge channel 3.3 and join with the pen barrel under the action of the discharge rod 3.7. This realizes the automatic assembly of some components of the marker pen and greatly improves production efficiency.

[0038] Specifically, the joining channel 3.2 has a feeding position opposite to the output ends of the first feeding module 1.1 and the second feeding module 1.2, a joining position opposite to the joining rod 3.4, and a discharging position opposite to the discharging channel 3.3. The joining seat 3.1 is provided with a limiting stop 3.6, which is arranged along the outer contour of the joining plate 1.4. The limiting stop 3.6 is located between the feeding position and the discharging position to restrict the cotton core and components from leaving the joining channel 3.2.

[0039] During the rotation of the joining plate 1.4, the cotton core and middle section are first fed at the feeding position, then rotated to the joining position for joining, and finally rotated to the discharge position so that the joined middle section and cotton core fall into the discharge channel 3.3. The limiting edge 3.6 is used to limit the cotton core and middle section to prevent them from detaching from the joining plate 1.4 during the rotation.

[0040] Furthermore, a positioning component 4.1 is provided on the joining seat 3.1. The positioning component 4.1 includes a positioning block 4.2 and a positioning cylinder 4.3 that drives the positioning block 4.2 to move. When the middle section and the cotton core are joined, the positioning block 4.2 abuts against the middle section. When the joining plate 1.4 rotates to the joining position, the positioning cylinder 4.3 will drive the positioning block 4.2 to move and abut against the middle section, so as to prevent the middle section from shifting during the joining process and improve the joining quality of the middle section and the cotton core.

[0041] Preferably, the discharge rod 3.7 is mounted on the sliding block 5.1, and a detection rod 5.2, which is positioned opposite to the pen barrel, is also inserted on the sliding block 5.1. The detection rod 5.2 is spaced apart from the discharge rod 3.7, and an elastic element 5.3 is sleeved on the detection rod 5.2. One end of the elastic element 5.3 abuts against the detection rod 5.2, and the other end abuts against the sliding block 5.1, so that the detection rod 5.2 always has a tendency to move toward the pen barrel. A sensing ring 5.4 is provided at the end of the detection rod 5.2, and a position sensor 5.5 for the sensing ring 5.4 is provided on the sliding block 5.1.

[0042] The conveying structure 2 will convey the pen barrel, which has been joined with the middle section and the cotton core, along the length of the conveying structure 2, so that it is positioned opposite the detection rod 5.2. The detection rod 5.2 abuts against the middle section, and the sensing ring 5.4 at the end of the detection rod 5.2 cooperates with the position sensor 5.5 to determine whether the middle section and the cotton core are installed in place, thereby further improving the assembly quality.

[0043] Preferably, a repressing rod 5.6 is also inserted on the sliding block 5.1, and the repressing rod 5.6 and the detection rod 5.2 are arranged at intervals. After being detected by the detection rod 5.2, the pen barrel is set opposite to the repressing rod 5.6 under the conveying structure 2. The repressing rod 5.6 will squeeze the middle section again, thereby ensuring the joint quality between the pen barrel and the middle section.

[0044] Preferably, the connecting seat 3.1 is also provided with a material drop bar, which is placed in the rotation path of the connecting channel 3.2 to prevent the middle section that is connected to the cotton core from not disengaging from the connecting channel 3.2.

[0045] like Figure 4 , Figure 5 As shown, in some other embodiments, the output end of the discharge channel 33 on the coupling seat 3.1 is formed with an extension protrusion 8.5, and a limiting protrusion 8.6 is formed inside the extension protrusion 8.5. A pressing protrusion 8.7 that moves up and down is provided above the extension protrusion 8.5. The pressing block and the extension protrusion 8.5 form a joint space 8.9 for the pen barrel and the middle section to join. The limiting protrusion 8.6 can limit the movement stroke of the middle section, thereby ensuring the joining quality of the pen barrel and the middle section.

[0046] Preferably, the machine tool 1 is also equipped with a defective product rejection assembly 6.1. The defective product rejection assembly 6.1 includes a mounting bracket 6.2 disposed on the side of the conveying structure 2, and a rejection cylinder 6.3 fixed on the mounting bracket 6.2, with the rejection cylinder 6.3 facing the conveying structure 2.

[0047] The defective product rejection component 6.1 is located at the rear of the detection rod 5.2. When a defective product is detected, the rejection cylinder 6.3 will push the corresponding pen rod out of the conveying structure 2, thereby ensuring the quality of product assembly.

[0048] like Figures 1 to 3 As shown, further explanation of the conveying structure 2 in this embodiment: the conveying structure 2 includes a first conveying plate 7.1 fixedly mounted on the machine base 1, a second conveying plate 7.2 movably mounted on the machine base 1, and a drive rod assembly 7.3 for driving the second conveying plate 7.2 to move up, down, left, and right. The first conveying plate 7.1 has a first receiving groove 7.4 for receiving the pen barrel, and the second conveying plate 7.2 has a second receiving groove 7.5 for receiving the pen barrel. The first receiving groove 7.4 and the second receiving groove 7.5 are staggered. The drive rod assembly 7.3 includes a drive rod 8.1, an eccentric drive wheel 8.2 sleeved on the drive rod 8.1, a connecting rod 8.3 connected to the bottom of the second conveying plate 7.2, and a drive unit 8.4 for driving the drive rod 8.1 to rotate.

[0049] During the pen transport process, the eccentric drive wheel 8.2 drives the connecting rod 8.3 to rotate, thereby driving the second transport plate 7.2 to swing up, down, left, and right in a circular motion. The second transport plate moves upward and forward, causing the pen in the first receiving groove 7.4 to fall into the second receiving groove 7.5. As the second transport plate moves downward and backward, the pen in the second receiving groove 7.5 falls into the next second receiving groove 7.5, thus realizing the transport of the pen.

[0050] Furthermore, the machine tool 1 is also equipped with a pressure rod assembly 9.1, which includes a pressure bracket 9.2 and several pressure rods 9.3 set on the pressure bracket 9.2. The drive rod 8.1 is fitted with a lifting eccentric wheel 9.4 that drives the pressure bracket 9.2 to move up and down. The pressure bracket 9.2 rises and falls with the operation of the conveying structure 2, and the pressure rods 9.3 correspond to some assembly positions. During the assembly process, they will press the pen barrel, further improving the assembly quality.

[0051] In addition, the output end of the conveyor structure 2 is also equipped with a receiving frame to collect the assembled markers.

[0052] Preferably, the clamping protrusion 8.7 is provided on the clamping bracket 9.2 to ensure stability during the connection process between the pen barrel and the middle section.

[0053] like Figure 1 , Figure 2 As shown, as a further explanation of the pen barrel feeding structure 3, the pen barrel feeding structure 3 includes a feeding tray 9.5 and a feeding channel 9.6, and a pushing cylinder 9.7 is provided on the machine base 1. A pushing plate 9.8 is connected to the actuating end of the pushing cylinder 9.7. When the pushing cylinder 9.7 is actuated, the pushing plate 9.8 pushes the pen barrel in the feeding channel 9.6 into the conveying structure 2.

[0054] During the feeding process, the feeding tray 9.5 conveys the pen barrel to the machine base 1 through the feeding channel 9.6, and pushes the pen barrel at the bottom of the feeding channel 9.6 into the conveying structure 2 through the unloading plate, thus realizing the automatic feeding of the pen barrel.

[0055] like Figure 6 , Figure 7 As shown, further explanation of the flat pen tip mounting structure 5 and pen cap mounting structure 6 in this embodiment: the first receiving plate 2.2 is also slidably provided with a pressure bar 5.6, and the machine base 1 is also provided with a vertically arranged detection bar 5.2 to detect the flat pen tip mounting.

[0056] In addition, the second receiving plate 2.5 is also slidably equipped with a detection rod 5.2 to detect the installation of the pen cap, so as to ensure the quality of the pen cap installation.

[0057] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
