Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ball-point pens, in particular to an automatic assembly machine for ball-point pens. BACKGROUND

[0002] Ball-point pens use dry and thick ink, and are a writing tool that uses a ball at the front end of the pen or the pen core to roll and bring out the writing medium. Ball-point pens are a kind of pen that uses a small rotating ball made of brass, steel or tungsten carbide to release ink onto paper during writing. Ball-point pens have the advantages of simple structure, easy to carry, smooth writing, and suitable for copying.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example

[0036] like Figures 1-7 As shown in the figure, an automated ballpoint pen assembly machine according to one embodiment of the present invention includes a processing table 1. The top of the processing table 1 is provided with a conveying structure 2, a guiding structure 4, a pen refill insertion structure 6, a back cover insertion structure 7, and two top pressing structures 8. The discharge end of the conveying structure 2 is fixedly connected to a finished product groove 5. The guiding structure 4, the pen refill insertion structure 6, and the back cover insertion structure 7 are all located obliquely behind the conveying structure 2. The inlet of the guiding structure 4 is provided with a feeding structure 3. The top pressing structures 8 are located inside the conveying structure 2, and the two top pressing structures 8 are respectively located in front of the discharge outlets of the pen refill insertion structure 6 and the back cover insertion structure 7.

[0037] The conveying structure 2 comprises a driving support 201, an internal wall of the driving support 201 is fixedly installed with an internal motor 202, the driving support 201 is drivingly connected with a conveying chain 203 through the internal motor 202, and the outer side of the conveying chain 203 is fixedly connected with clamping strips 204, and the pen barrel body 9 is placed between the two clamping strips 204.

[0038] By means of the design of the conveying structure 2, the conveying chain 203 is circularly rotated under the driving of the internal motor 202, thereby driving the clamping strips 204 and the pen barrel bodies 9 thereon to sequentially pass through the guiding structure 4, the lead insertion structure 6, the back cover insertion structure 7 and the top material pressing structure 8, and the whole assembly process is completed. The design of each clamping strip 204 ensures that the pen barrel body 9 is stable and does not fall off during the conveying process, and facilitates accurate positioning in the subsequent assembly steps.

[0039] The guiding structure 4 comprises a falling slide rail 401, the falling slide rail 401 is located above the conveying chain 203, the bottom end of the falling slide rail 401 is fixedly installed with a discharging plate 402, the back side of the falling slide rail 401 is fixedly installed with a side-mounted electric push rod 403, the movable end of the side-mounted electric push rod 403 is fixedly installed with a closing plate 404, and the closing plate 404 is located between the falling slide rail 401 and the discharging plate 402.

[0040] In the guiding structure 4, the design of the falling slide rail 401 enables the pen barrel body 9 to smoothly slide in, and the opening composed of the falling slide rail 401 and the discharging plate 402 is opened and avoided by the closing plate 404 driven by the side-mounted electric push rod 403, so that the pen barrel body 9 can fall one by one and accurately enter the specified position of the conveying chain 203.

[0041] The lead insertion structure 6 comprises a rear frame 601, a storage cavity 602 is formed in the inside of the rear frame 601, a flip cover 603 is hingedly connected to the front side of the storage cavity 602, a storage box 604 is fixedly installed at the top end of the rear frame 601, the storage box 604 is located at the feeding port of the storage cavity 602, and a lead body 605 is placed in the inside of the storage box 604.

[0042] The lead body 605 in the storage cavity 602 is automatically and accurately inserted into the pen barrel body 9 by means of the design of the transfer box 606 and the transfer port 607, in cooperation with the push plate 610 driven by the rear-mounted electric push rod 609. The design of the storage box 604 facilitates the replenishment of the lead body 605, and the flip cover 603 ensures the orderly arrangement of the lead body 605 before insertion.

[0043] As Figure 1As shown, in some embodiments, the front end of the processing table 1 is fixedly installed with a control panel, which is electrically connected with the conveying structure 2, the feeding structure 3, the guiding structure 4, the refill inserting structure 6, the back cover inserting structure 7 and the top material pressing structure 8 respectively.

[0044] Specifically, by using the control panel, the operator can conveniently control the operation of the entire ballpoint pen automatic assembly machine. The control panel integrates the control instructions of each structural unit, so that the entire assembly process can be automatically and orderly performed under the preset program. Through the control panel, the conveying speed, the assembly position and the pressing force and other key parameters can be monitored and adjusted in real time, ensuring the high precision and stability of the assembly process.

[0045] As shown in the Figure 3 As shown, in some embodiments, the feeding structure 3 includes an external bracket 301, the top end of which is fixedly installed with a feeding box 302, and the side end of the feeding box 302 is fixedly installed with a scraper conveyor 303, which is driven by an external driving source 304 inside the external bracket 301.

[0046] Specifically, before starting the operation, the staff first carefully places the pen barrel bodies 9 in the feeding box 302 according to the specified number and arrangement, ensuring that each pen barrel body 9 is placed neatly and stably.

[0047] Subsequently, the scraper conveyor 303 starts to convey the pen barrel bodies 9 in the feeding box 302 one by one and in order to the opening of the falling slide rail 401 according to the preset speed and rhythm under the stable and continuous power driving provided by the external driving source 304.

[0048] In this process, the running state and conveying speed of the scraper conveyor 303 are strictly monitored to ensure that each pen barrel body 9 can accurately reach the designated position, laying a foundation for the smooth progress of the subsequent process.

[0049] As shown in the Figure 3 As shown, in some embodiments, the bottom end of the inner wall of the feeding box 302 is a slope, and the lowest point of the slope is located at the feeding position of the scraper conveyor 303, and the discharging end of the scraper conveyor 303 is located at the opening of the falling slide rail 401.

[0050] Specifically, the inner wall of the feeding box 302 is designed as a slope, which helps the pen barrel bodies 9 to smoothly slide to the feeding position of the scraper conveyor 303 under the action of gravity. The lowest point of the slope is accurately aligned with the inlet of the scraper conveyor 303, ensuring that the pen barrel bodies 9 can be accurately conveyed to the next process.

[0051] The discharge end of the scraper conveyor 303 is ingeniously arranged at the opening of the falling slide rail 401, so that the pen barrel body 9 accurately conveyed by the scraper conveyor 303 can directly slide into the falling slide rail 401, preparing for the subsequent guiding and assembling steps.

[0052] As Figure 5 shown, in some embodiments, a transfer box 606 is fixedly installed at the opening of the bottom end of the storage cavity 602, and a transfer opening 607 is formed in the inside of the transfer box 606, the size of which is matched with the specification of the pen core body 605.

[0053] Specifically, the pen core body 605 is pre-positioned and properly stored in the dedicated storage box 604 in the initial stage to ensure its safety and convenient access. Then, the operator will accurately align and dock the discharge opening of the storage box 604 to the corresponding position of the storage cavity 602, and through the adjustment of the relative position, the pen core body 605 can smoothly and automatically enter the internal space of the storage cavity 602. In this process, the design of the storage cavity 602 ensures the smooth sliding of the pen core body 605, avoiding any possibility of jamming or misoperation.

[0054] Subsequently, when the pen core body 605 in the storage cavity 602 accumulates to a certain number, the pen core body 605 at the bottom will naturally fall into the transfer opening 607 specially formed in the inside of the transfer box 606 under the action of gravity.

[0055] The transfer opening 607 can only accommodate one pen core body 605 at a time, which effectively avoids the confusion or blockage caused by the simultaneous falling of multiple pen cores, ensuring the single flow direction and orderly transfer of the pen core body 605 during the transfer process. Through this precise mechanical cooperation and design, the storage and transfer process of the entire pen core is efficiently and accurately carried out.

[0056] As Figure 5 shown, in some embodiments, a lifting platform 608 is fixedly installed on the inner wall of the rear frame 601, a rear electric push rod 609 is fixedly installed at the top end of the lifting platform 608, a push plate 610 is fixedly installed at the movable end of the rear electric push rod 609, the push plate 610 extends to the inside of the transfer opening 607 through the opening at the back side of the transfer opening 607, and the front end of the push plate 610 is lapped with the back end of the pen core body 605 located in the inside of the transfer opening 607.

[0057] Specifically, when the refill body 605 in the storage cavity 602 falls to the transfer port 607, the rear electric push rod 609 located at the back side of the transfer port 607 is immediately started. The refill body 605 located inside the transfer port 607 is accurately pushed forward by the push plate 610 installed at the movable end of the rear electric push rod 609. The design of the push plate 610 ensures that the front end of the push plate 610 can tightly fit the back end of the refill body 605, thereby providing stable support and guidance during the pushing process, avoiding the deviation or inclination of the refill body 605 during the pushing process. As the push plate 610 gradually advances, the refill body 605 is accurately pushed to the assembly position corresponding to the pen barrel body 9, preparing for the subsequent assembly steps.

[0058] As shown in Figure 6 In some embodiments, the rear cover insertion structure 7 includes a vertical support 701, an installation plate 702 and a back side electric push rod 703 are fixedly installed on the outer side of the vertical support 701, a vertical rail 705 is fixedly installed at the top end of the installation plate 702, a rear cover body 706 is placed inside the vertical rail 705, a push block 704 is fixedly installed at the movable end of the back side electric push rod 703, a through hole is formed in the inner wall of the vertical rail 705, and the push block 704 passes through the through hole and overlaps with the back end of the lowermost rear cover body 706.

[0059] Specifically, the design of the vertical rail 705 not only ensures the stable movement of the rear cover body 706 in the vertical direction, but also ensures the accurate positioning of the rear cover body 706 during the assembly process. The movable end of the back side electric push rod 703 overlaps with the back end of the rear cover body 706 through the push block 704. This design enables the rear cover body 706 to move smoothly and accurately along the vertical rail 705 to the tail end of the pen barrel body 9 under the drive of the back side electric push rod 703, completing the assembly action

[0060] The vertical rail 705 ensures the stability of the movement of the rear cover body 706 in the vertical direction, and fundamentally ensures the accurate positioning of the rear cover body 706 during the entire assembly process.

[0061] The movable end of the back side electric push rod 703 overlaps with the back end of the rear cover body 706 through the push block 704. This overlapping manner ensures that the rear cover body 706 can move smoothly and without deviation along the vertical rail 705 under the strong driving action of the back side electric push rod 703. Finally, the rear cover body 706 can accurately and accurately move to the tail end position of the pen barrel body 9, thereby smoothly completing the entire assembly action, ensuring the efficiency and accuracy of the assembly process.

[0062] As shown in Figure 7As shown, in some embodiments, the material pressing structure 8 comprises an embedded bracket 801 and a front bracket 802, the movable end of the embedded bracket 801 is fixedly installed with a lower electric push rod 803, the movable end of the lower electric push rod 803 is fixedly installed with a material pressing plate 804, and the top end of the front bracket 802 is fixedly installed with a pressing pile 805.

[0063] Specifically, in the material pressing structure 8, the embedded bracket 801 stably supports the lower electric push rod 803, ensuring its stable operation.

[0064] The movable end of the lower electric push rod 803 is closely connected to the material pressing plate 804, when the pen barrel body 9 moves to the front position of the refill inserting structure 6 and the rear cover inserting structure 7 during the conveying process, the material pressing plate 804 will move upward smoothly and accurately under the accurate driving of the lower electric push rod 803.

[0065] This action stably lifts the pen barrel body 9 to the position directly below the pressing pile 805, at this time, the pressing pile 805 will apply appropriate and uniform pressure to the pen barrel body 9.

[0066] In this process, the pen barrel body 9 will smoothly separate from the support of the conveying structure 2, at the same time, the refill inserting structure 6 and the rear cover inserting structure 7 can respectively gradually and accurately interface and assemble the refill body 605 and the rear cover body 706 with the internal structure of the pen barrel body 9, thereby completing the entire pen barrel assembly process.

[0067] As Figure 7 shown, in some embodiments, the material pressing plate 804 is located below the gap between the two clamping strips 204, and the pressing pile 805 is located above the material pressing plate 804.

[0068] Specifically, this design of the material pressing plate 804 ensures that it will not interfere with the clamping strips 204 on the conveying chain 203 when lifting the pen barrel body 9, and at the same time, the accurate positioning of the pressing pile 805 guarantees the stability and accuracy during the assembly process.

[0069] When the material pressing plate 804 lifts the pen barrel body 9 to an appropriate height, the pressing pile 805 will quickly and smoothly descend to apply appropriate pressure to the pen barrel body 9, so that the refill body 605 and the rear cover body 706 can be tightly assembled in the pen barrel body 9.

[0070] In use, first, the pen barrel body 9 is introduced into the upper feeding box 302, the refill body 605 is introduced into the storage box 604, and the rear cover body 706 is introduced into the vertical rail 705, then the assembly machine is started through the control panel, and the entire assembly process will be automatically and orderly performed under the preset program.

[0071] Firstly, the scraper conveyor 303 starts to transport the pen barrel body 9 in the feeding box 302 one by one and orderly to the opening of the falling slide rail 401 according to the preset speed and rhythm under the stable and continuous power driving of the external driving source 304.

[0072] The design of the falling slide rail 401 enables the pen barrel body 9 to smoothly slide in, and the opening of the falling slide rail 401 and the discharging plate 402 is timely opened and closed by the closing plate 404 driven by the side-mounted electric push rod 403, so as to ensure that the pen barrel body 9 can fall one by one and accurately enter the specified position of the conveying chain 203.

[0073] Then, the conveying chain 203 is driven to rotate circularly by the built-in motor 202, and the clamping strip 204 and the pen barrel body 9 thereon pass through the lead insert structure 6, the back cover insert structure 7 and the top material pressing structure 8 in turn.

[0074] During this process, the top material plate 804 moves upward stably and accurately under the accurate driving of the lower electric push rod 803, which stably lifts the pen barrel body 9 to the position directly below the pressing pile 805, and the pressing pile 805 applies appropriate and uniform pressure to the pen barrel body 9 at this time.

[0075] During this process, the pen barrel body 9 is smoothly separated from the support of the conveying structure 2, and at the same time, the lead insert structure 6 and the back cover insert structure 7 can respectively gradually and accurately connect and assemble the lead body 605 and the back cover body 706 with the internal structure of the pen barrel body 9, so as to complete the combination process of the whole pen barrel;

[0076] When the lead body 605 in the storage cavity 602 falls to the transfer port 607, the rear electric push rod 609 located at the back side of the transfer port 607 is started. The rear electric push rod 609 accurately pushes the lead body 605 inside the transfer port 607 forward through the push plate 610 mounted on the movable end of the rear electric push rod 609. The design of the push plate 610 ensures that the front end of the push plate 610 can tightly fit the back end of the lead body 605, so as to provide stable support and guidance during the pushing process, avoiding the deviation or inclination of the lead body 605 during the pushing process. With the gradual advancement of the push plate 610, the lead body 605 is accurately pushed to the assembly position corresponding to the pen barrel body 9;

[0077] Subsequently, the movable end of the back electric push rod 703 is overlapped with the back end of the back cover body 706 through the push block 704. This overlapping mode ensures that the back cover body 706 can move smoothly and without deviation along the vertical rail 705 under the strong driving action of the back electric push rod 703. Finally, the back cover body 706 can accurately and accurately move to the tail end position of the pen barrel body 9, thereby smoothly completing the entire assembly action and ensuring the efficiency and accuracy of the assembly process.

[0078] In summary, through the conveying structure 2, the feeding structure 3 and the guiding structure 4, the pen barrel body 9 can be sent into the conveying structure 2 through the guiding structure 4 by the feeding structure 3, so that each pen barrel body 9 can be individually conveyed, and the pen barrel body 9 can be transferred to the refill insertion structure 6 and the back cover insertion structure 7 for assembly of different accessories by the conveying structure 2, thereby providing a continuous work flow for subsequent assembly steps, avoiding misplacement and deviation during assembly, and improving assembly accuracy.

[0079] Through the refill insertion structure 6 and the back cover insertion structure 7, the refill body 605 and the back cover body 706 can be automatically and accurately embedded into the pen barrel body 9 without manual intervention. Not only does this improve the assembly speed of the refill and the back cover, making the entire assembly process more efficient and smooth, but it also ensures a high degree of consistency and accuracy for each assembly, avoiding assembly errors caused by improper manual operation, thereby significantly improving the overall quality of the product and user experience.

[0080] It should be noted that the specific model specifications of the scraper conveyor 303, the external drive source 304, the side electric push rod 403, the rear electric push rod 609, the back electric push rod 703, and the lower electric push rod 803 in the ballpoint pen automatic assembly machine need to be determined according to the actual specifications of the device. The specific selection calculation method uses existing technology in the field, so it will not be described in detail.

[0081] Furthermore, the power supply and principles of the scraper conveyor 303, the external drive source 304, the side electric push rod 403, the rear electric push rod 609, the back electric push rod 703, and the lower electric push rod 803 in the ballpoint pen automatic assembly machine are clear to those skilled in the art, and will not be described in detail here.
