Description

Technical Field

[0001] The invention relates to the technical field of automatic pen assembly, and in particular to a pen clip seat positioning assembly device and method. Background Art

[0002] A pen usually includes a pen clip holder, a pen clip and a pen barrel. Both the pen clip holder and the pen clip have a clamping part. The pen clip holder and the pen clip are positioned by a slot structure so that the angles of the clamping parts of the two are consistent, which is convenient for subsequent assembly. In the conventional assembly process of the pen clip holder, the pen clip is first rotated and positioned and assembled to the pen barrel, and then the pen clip holder is assembled to the pen clip. Since the clamping part of the pen clip holder and the clamping part of the pen clip need to maintain the same angle, the following process is usually used to complete the assembly in production: the pen clip holder is aligned with a vibration disk, and the pen clip holder is aligned to the side with the clamping part facing the moving direction of the pen clip holder (that is, the clamping part is perpendicular or approximately perpendicular to the moving direction of the pen clip holder); the aligned pen clip holder is clamped onto the pen clip by a clamping claw; the pen clip holder and the pen clip are pressed together by pressing.

[0003] Since the pen clip holder and the pen clip are positioned by the slot structure, only accurate installation can avoid damage to the product during the subsequent pressing process due to the misalignment of the angle between the pen clip holder and the pen clip. However, the clamping part of the pen clip holder is aligned vertically or approximately vertically to the moving direction of the pen clip holder through the vibration plate, which easily leads to angle differences in the movement of the pen clip holder, and eventually leads to assembly failure due to incorrect angles, resulting in a waste of maintenance time and materials, and also creates additional risks to the equipment.

[0004] In addition, in order to smoothly match the pen clip holder with the production rhythm, the limit gap on the vibration plate is usually not set too tightly. However, a too tight limit gap will slow down the discharge speed, while a relatively large limit gap will affect the final positioning accuracy, causing the direction and angle of the entire column of the pen clip holder to deviate, and ultimately lead to assembly failure due to incorrect angles. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0032] The pen clip seat positioning and assembling device disclosed in the present invention can accurately assemble the pen clip seat onto the pen clip, thereby avoiding damage to the pen clip seat and the pen clip.

[0033] Combination Figure 1 to Figure 3 As shown, a pen clip seat positioning and assembly device disclosed in the present invention includes a vibration plate, at least one pen clip seat positioning and rotating mechanism 20, a pen clip seat clamping mechanism 30 and a pen clip seat assembly mechanism 40, wherein the vibration plate is used to make the clamping portion of the pen clip seat face the preset pen clip seat moving direction and transport the pen clip seat outward; the pen clip seat positioning and rotating mechanism 20 is arranged close to the vibration plate, and is used to position the pen clip seat and rotate the pen clip seat by a preset angle to ensure that the clamping portion angles of the pen clip seat and the pen clip are consistent during assembly; the pen clip seat clamping mechanism 30 is arranged close to the vibration plate, and is used to clamp the pen clip seat on the vibration plate and place the pen clip seat on the pen clip seat positioning and rotating mechanism 20 for positioning and rotating by a preset angle; the pen clip seat assembly mechanism 40 is arranged close to the vibration plate, and is used to assemble the pen clip seat rotated by a preset angle on the pen clip seat positioning and rotating mechanism 20 to the pen clip.

[0034] like Figure 1 As shown, the vibration plate includes a hopper (not shown) and a flat vibration part 10 connected to the discharge port of the hopper (not shown). During implementation, a plurality of pen clip seats are placed in the hopper, and after the vibration of the hopper, the plurality of pen clip seats are transported to the flat vibration part 10, and the clamping parts of the pen clip seats located in the flat vibration part 10 face the preset pen clip seat moving direction, and the flat vibration part 10 further transports the neatly arranged pen clip seats to the outside through vibration. Compared with the prior art, by aligning the vibration plate to change the direction of the clamping parts of the pen clip seats, the clamping parts of each pen clip seat face the preset pen clip seat moving direction, which can effectively reduce the requirements for the vibration plate and improve the alignment consistency of the pen clip seats.

[0035] Combination Figure 1 and Figure 3As shown, the pen clip seat positioning and rotating mechanism 20 includes a positioning seat 21, a rotating shaft 22 and a rotating driving mechanism, wherein the positioning seat 21 is used to position the pen clip seat, the positioning seat 21 is mounted on one end of the rotating shaft 22, and the other end of the rotating shaft 22 is connected to the rotating driving mechanism. During implementation, the pen clip seat is sleeved on the positioning seat 21 and positioned by the positioning seat 21, and the rotating driving mechanism further drives the positioning seat 21 to rotate through the rotating shaft 22, so that the pen clip seat sleeved on the positioning seat 21 rotates a preset angle.

[0036] In this embodiment, the rotation drive mechanism drives the pen clip holder to rotate 90 degrees via the rotation shaft 22. Of course, in other embodiments, the rotation angle of the pen clip holder can be set according to actual needs.

[0037] Furthermore, the positioning seat 21 adopts a contoured structure, and is provided with a positioning protrusion (not shown) that matches with the positioning slot of the pen clip seat to achieve positioning of the pen clip seat.

[0038] Further, the rotation drive mechanism includes a rotating gear 23, a rack 24 and a first power source 25, wherein the rotating gear 23 is connected to the rotating shaft 22, and the first power source 25 is connected to the rotating gear 23 through the rack 24.

[0040] Combination Figure 1 and Figure 2 As shown, the pen clip holder clamping mechanism 30 includes a first clamping jaw 31, a first clamping jaw cylinder 32 driving the first clamping jaw 31 to clamp the pen clip holder, and a second power source driving the first clamping jaw cylinder 32 to move. The first clamping jaw 31 is connected to the first clamping jaw cylinder 32, and the second power source is connected to the first clamping jaw cylinder 32. During implementation, the second power source drives the first clamping jaw cylinder 32 to move to a preset position, the first clamping jaw cylinder 32 further drives the first clamping jaw 31 to clamp the pen clip holder from the flat vibration part 10, and the first clamping jaw cylinder 32 further drives the first clamping jaw 31 to reset; the second power source continues to drive the first clamping jaw cylinder 32 to move to the positioning seat 21, and the first clamping jaw cylinder 32 further drives the first clamping jaw 31 to sleeve the pen clip holder on the positioning seat 21.

[0041] The pen clip seat assembly mechanism 40 includes a second clamping jaw 41, a second clamping jaw cylinder 42 that drives the second clamping jaw 41 to clamp the pen clip seat, and a third power source that drives the second clamping jaw cylinder 42 to move.

Since the pen clip holder is positioned and rotated to a preset angle by the pen clip holder positioning rotation mechanism 20, the positioning slot on the pen clip holder and the clamping protrusion on the pen clip are in the same straight line, that is, the clamping portion of the pen clip holder and the clamping portion of the pen clip maintain a consistent angle, thereby enabling the pen clip holder to be accurately assembled to the pen clip.

[0042] In this embodiment, the second power source and the third power source use the same clamping assembly drive mechanism 50, that is, the clamping assembly drive mechanism 50 can drive the first clamping jaw cylinder 32 and the second clamping jaw cylinder 42 to move synchronously. By setting up a clamping assembly drive mechanism for driving, the cost is reduced, the complexity of the device is reduced, and the space occupied is reduced.

[0043] Further, the gripping assembly driving mechanism 50 includes a fourth power source, a slider 51, and a guide rail 52 for guiding the slider 51 to move, wherein the slider 51 is slidably arranged on the guide rail 52 and is connected to the fourth power source.

[0045] In this embodiment, the fifth power source is preferably a cylinder. Of course, in other embodiments, the structure of the fifth power source can also be set according to actual needs, such as using a cam structure, etc.

[0046] The working principle of the pen clip holder positioning and assembling device of the present invention is as follows:

[0047] A plurality of pen clip seats are placed in the hopper, and after the hopper is vibrated, the plurality of pen clip seats are transported to the flat vibration part 10, and the clamping parts of the pen clip seats located in the flat vibration part 10 face the preset pen clip seat moving direction. The flat vibration part 10 further transports the neatly arranged pen clip seats to the dislocation plate 61 through vibration, and the dislocation plate 61 is driven by the fifth power source to achieve the dislocation processing of the pen clip seats;

[0048] The first power source 25 drives the first clamping jaw cylinder 32 to move to the preset position, the first clamping jaw cylinder 32 further drives the first clamping jaw 31 to clamp the pen clip seat from the offset plate 61, the first clamping jaw cylinder 32 further drives the first clamping jaw 31 to reset, the second power source continues to drive the first clamping jaw cylinder 32 to move to the positioning seat 21, the first clamping jaw cylinder 32 further drives the first clamping jaw 31 to sleeve the pen clip seat on the positioning seat 21 for positioning, and the rotary drive mechanism further drives the pen clip seat to rotate 90 degrees through the rotating shaft 22. At the same time, the third power source drives the second clamping jaw cylinder 42 to move to the preset position, the second clamping jaw cylinder 42 further drives the second clamping jaw 41 to clamp the pen clip seat placed in the previous cycle from the positioning seat 21, the second clamping jaw cylinder 42 further drives the second clamping jaw 41 to reset, the third power source continues to drive the second clamping jaw cylinder 42 to move to the pen clip, the second clamping jaw cylinder 42 further drives the second clamping jaw 41 to assemble the pen clip seat on the pen clip.

[0049] By repeating the above process, the pen clip holder can be accurately assembled onto the pen clip.

[0050] The pen clip seat positioning and assembly device of the present invention first realizes the first positioning of the pen clip seat through the vibration plate, so that the clamping part faces the preset pen clip seat moving direction, and then performs the second positioning through the positioning seat 21, thereby correcting the problem of the angle deviation of the pen clip seat, completely eliminating the influence of the angle deviation of the pen clip seat, and avoiding the problem of assembly damage caused by the angle deviation of the pen clip seat. In addition, the posture of the pen clip seat in the flat vibration part 10 of the vibration plate has changed, so the requirements for positioning accuracy are no longer strict, so the small pauses of the flat vibration are greatly reduced, so that the utilization rate of the equipment is improved and the maintenance cost of personnel is reduced.
