DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] like Figure 1-6 As shown, the pen neck assembly device 100 in one embodiment of the utility model includes a main frame 10, a displacement mechanism, an assembly mechanism and a monitoring mechanism. A track 11 is provided on the main frame 10, and the displacement mechanism includes a driving member 2121 fixed on the main frame 10, and a slider 22 limited in the track 11, and the driving member 2121 is connected to and drives the slider 22 to move in the track 11. The assembly mechanism includes a pen barrel operating component and a pen neck operating component, the former is used to fix the pen barrel, and the latter is used to fix the pen neck. The pen neck operating component is fixed on the slider 22, and tightens the pen neck to the pen barrel after following the slider 22 to move and approach the pen barrel. The monitoring mechanism includes a torque meter 41 fixed on the slider 22, which is used to monitor the torque value in real time during the tightening process, and stops rotating when the preset value is reached, so that the pen neck and pen barrel in the same specification of ballpoint pen or neutral pen can be tightened and fixed at a fixed value to prevent over-tightening or over-loosening.

[0027] Specifically, the pen neck operating assembly includes a rotating motor 321 and a first clamping member. The rotating motor 321 is fixed to the slider 22. The first clamping member is fixed to the output shaft of the rotating motor 321 and can rotate with the output of the rotating motor 321, forming a first clamping space for clamping the pen neck.

[0028] The pen operating assembly is arranged at the other end of the main bracket 10 along the extension direction of the track 11 (it can be fixed on the main bracket 10 or on other brackets of the entire assembly device), and includes a second clamping member, which forms a second clamping space for clamping the pen shaft, and the second clamping space is coaxial with the first clamping space.

[0029] When assembling a ballpoint pen or a gel pen, the first clamp and the second clamp fix the pen neck and the pen shaft respectively, and then the first clamp drives the pen neck close to the pen shaft under the action of the driving member 21, and at the same time, the pen neck is tightened to the pen shaft under the action of the rotating motor 321. During this process, the torque meter 41 monitors the rotational torque in real time, and sends a stop signal to the rotating motor 321 and the driving member 21 after reaching the preset value. The rotating motor 321 and the driving member 21 stop output at the same time, and then the driving member 21 reverses to drive the first clamp away from the assembled pen neck and pen shaft, and the single assembly process is completed.

[0030] like Figure 1-3 As shown, the driving member 21 in this embodiment is fixed on one side of the main support 10 ( Figure 1 The servo motor is connected to the upper side of the figure (in the figure), and its output shaft is connected to one end of the screw rod 24. The other end of the screw rod 24 is rotatably arranged on the other side of the main support 10, that is, the lower side in the figure. The slider 22 is inserted into the screw rod 24 and is threadedly engaged with the screw rod 24. Therefore, when the servo motor is running, the screw rod 24 rotates accordingly, and the slider 22 moves in the track 11 under the action of the thread. In addition to the servo motor and the screw rod 24, a cylinder or other power device can also be used to drive the slider 22 to move, which is not limited in this embodiment.

[0031] To facilitate the installation of the fixed rotating motor 321 and the torque meter 41, as shown in FIG. Figure 1-3 As shown, the displacement mechanism further includes a support plate 23 fixed to the slider 22 . The support plate 23 is used to provide a larger installation space. The rotary motor 321 and the torque meter 41 are fixed on the support plate 23 .

[0032] In one embodiment, the first clamping member includes a clamping claw cylinder 322 and a clamping claw 323 fixed on the output shaft of the clamping claw cylinder 322. The first clamping space is formed between the clamping claws 323. The clamping claw cylinder 322 is used to drive the clamping claws 323 to move closer to each other to clamp the pen neck, or to move away from each other to release the pen neck. Figure 1 and 5 The illustrated embodiment adopts a two-finger clamp structure. To improve the stability of clamping the pen neck, a three-finger or more clamp structure may also be adopted, and this embodiment is not limited thereto.

[0033] Preferably, the pen neck operating assembly also includes a bearing 324 and a connecting rod 325, the bearing 324 is fixed on the support plate 23, the connecting rod 325 is fixed to the inner ring of the bearing 324, the output shaft of the rotating motor 321 and the connecting rod 325 are respectively fixed with a first gear 326 and a second gear 327, the two are meshed with each other, the clamping cylinder 322 is fixed to the end of the connecting rod 325, so that the rotating motor 321 drives the connecting rod 325 and the clamping cylinder 322, and the clamping claw 323 to rotate when outputting.

[0034] Combination Figure 4 As shown, further, a counter 42 is provided on the support plate 23, and a counting nut 43 is provided on the second gear 327, and the two constitute a rotation monitoring assembly, and the counter 42 can monitor the rotation number of the connecting rod 325 and the pen neck by sensing the number of times the nut 43 passes. The rotation monitoring assembly cooperates with the torque meter 41 to jointly monitor the assembly process of the pen neck and the pen holder.

[0035] Two counting nuts 43 are arranged on the second gear 327, and the two counting nuts 43 are in the same diameter, so the cycle monitoring assembly counts in units of half a cycle, and the monitoring accuracy is higher. Of course, the counting nuts 43 can also be set to other numbers, and this embodiment is not limited.

[0036] In one embodiment, the diameter of the second gear 327 is larger than that of the first gear 326. When the first gear 326 rotates one circle, the second gear 327 rotates only a part of the angle, so the rotation speed of the second gear 327 is lower than that of the first gear 326. Through the above arrangement, a differential structure is added to the assembly mechanism to reduce the rotation speed when the pen neck is tightened to the pen holder, so as to prevent the pen neck from being damaged due to the failure to stop rotating in time due to excessive rotation speed, thereby improving the stability during assembly.

[0037] Furthermore, a detection ruler 25 ( Figure 2 ), a displacement sensor 26 is correspondingly fixed on the main support 10, and the displacement sensor 26 is arranged on one side of the pen barrel operating assembly and is connected to the servo motor for communication. When the support plate 23 moves toward the side of the pen barrel, after sensing the detection ruler 25, the displacement sensor 26 immediately sends a signal to the servo motor, the servo motor stops outputting, and the support plate 23 stops moving. The detection ruler 25 and the displacement sensor 26 cooperate to add a safety mechanism to the pen neck assembly device 100, which is used to force the servo motor to reverse when a communication or other failure occurs in the pen neck assembly device 100, resulting in the servo motor not being correctly reversed after the pen neck is assembled and continuing to move toward the pen barrel operating assembly, thereby preventing damage to the device.

[0038] Combination Figure 5 As shown, in one embodiment, a positioning plate 328 is further provided on the clamping claw cylinder 322, and a positioning hole 3281 capable of accommodating the tip of the pen neck is provided on the positioning plate 328, and the positioning hole 3281 is coaxial with the first clamping space and the second clamping space. The positioning plate 328 is used to adjust the posture of the pen neck so that the pen neck contacts the pen holder in a correct posture. And preferably, the positioning plate 328 can be made of a flexible material such as rubber, which can increase friction to prevent heel rotation and prevent the pen neck and / or pen holder from cracking.

[0039] like Figure 1 and 3As shown, the pen barrel operating assembly includes two clamping cylinders 311 arranged opposite to each other, and the second clamping member includes two clamping plates 312 respectively fixed to the output ends of the two clamping cylinders 311, and each clamping plate 312 is provided with a semi-cylindrical clamping groove. After the two clamping plates 312 are driven to approach by the clamping cylinders 311 at their respective ends, the two clamping grooves are combined into a cylindrical groove body (second clamping space) for clamping the pen barrel. After the assembly is completed, the clamping cylinders 311 on both sides drive the clamping plates 312 at their respective ends to move away from each other, and the pen barrel loses the restriction of the clamping plates 312 and can be separated from the pen neck assembly device 100.

[0040] Preferably, Figure 6 As shown, each clamping plate 312 is respectively fixed with a flexible rubber block 313, and the two rubber blocks 313 cooperate to clamp the pen holder, and the position where the rubber block 313 contacts the pen holder is similar to that of the clamping plate 312. The two rubber blocks 313 are used to ensure the posture of the pen holder, and the flexible material can increase the friction to prevent the pen holder from being crushed while preventing it from rotating.

[0041] In this embodiment, in order to increase the number of assemblies in a single operation, Figure 1-3 The pen neck assembly device 100 shown includes two sets of assembly mechanisms, which can assemble two ballpoint pens or gel pens at a time. Of course, the assembly mechanisms can be provided in other numbers, and this embodiment is not limited thereto. It is conceivable that, in order to cooperate with the above-mentioned setting, each set of assembly mechanisms is equipped with a torque meter 41 and a rotation monitoring component.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
