Description

Technical Field

[0001] The invention relates to the technical field of automobile glass processing, and in particular to a drawing device for installing a nail column and a nail column installation method thereof. Background Art

[0002] The installation of nail posts is an important step in the processing of automotive glass. The traditional method of installing nail posts is to install them manually, which is inefficient.

[0003] With the improvement of production automation level, various automatic installation devices for nail posts have begun to be developed. Most automatic installation devices for nail posts use a mechanical structure to press the nail posts on the glass surface, and then lift the mechanical structure to prepare for the next installation.

[0004] During the lifting process of the mechanical structure, the nail column often moves up and becomes misaligned. Especially for the nail column pasted with polyurethane glue, since the polyurethane glue solidifies slowly, the scratches during the lifting process of the mechanical structure seriously affect the installation of this type of nail column, and cannot meet the automatic installation of the nail column. Summary of the invention

[0005] The purpose of the present invention is to provide a drawing device for installing a nail column in view of the technical defect that the prior art cannot meet the requirements of automatic installation of nail columns.

[0006] Another object of the present invention is to provide a nail post installation method using the above-mentioned extraction device for nail post installation.

[0007] The technical solution adopted to achieve the purpose of the present invention is:

[0008] A pulling device for installing a nail column, comprising a turning mechanism, a pressing mechanism and a pulling mechanism;

[0009] The flip mechanism comprises a flip cylinder mounted on a mounting base and a flip arm mounted on an output shaft of the flip cylinder and flipped accordingly;

[0010] The pressing mechanism comprises a pressing cylinder installed at the end of the flip arm and a second bracket driven by the pressing cylinder to move up and down;

[0011] The drafting mechanism comprises a drafting cylinder and a nail column support member fixedly mounted on the second bracket, and a contour-profiling limit block driven by the drafting cylinder; the contour-profiling limit block is sleeved on the nail column support member.

[0012] In the above technical solution, the mounting base includes a first base, a second base and a mounting frame; the second base is longitudinally slidably connected to the first base; and the mounting frame is transversely slidably connected to the second base.

[0013] In the above technical solution, the flipping mechanism is also provided with a stabilizing component.

[0014] In the above technical solution, the stabilizing assembly includes a stabilizing limit plate fixedly mounted on the mounting base, a stabilizing cylinder mounted on the stabilizing limit plate, a pressure stabilizing member mounted on the piston rod of the stabilizing cylinder, and a supporting member mounted on the stabilizing limit plate.

[0015] In the above technical solution, the support member includes a buffer and a supporting bolt.

[0016] In the above technical solution, the clamping cylinder is installed at the end of the flip arm through a first bracket.

[0017] In the above technical solution, the second bracket is L-shaped; a vertical right-angle side of the second bracket is slidably mounted on the first bracket through a first slide rail slider assembly.

[0018] In the above technical solution, the contoured limit block includes a sliding portion, a connecting portion and a limiting portion; the sliding portion is slidably connected to the second bracket through a second slide rail slider assembly; the lower end of the nail column support passes through the connecting portion and is nested inside the limiting portion.

[0019] In the above technical solution, the limiting portion is provided with a nail column profiling hole; the shape of the nail column profiling hole is consistent with the outer edge shape of the nail column support.

[0020] In another aspect of the present invention, the nail column installation method of the above-mentioned extraction device includes the following steps:

[0021] First, the flip arm is in a non-flipped state, and the nail column to be installed is placed in the contour limit block;

[0022] Then, the flip cylinder is started to flip the flip arm to the flip state, and the pressing cylinder is started to press downward to stick the nail column to be installed in the nail column profiling hole on the glass;

[0023] Then, after the pasting is completed, the pulling cylinder is retracted, driving the contour limit block upward; the pressing cylinder is lifted upward, and the nail column support is lifted upward accordingly, leaving the nail column on the glass surface;

[0024] Finally, the flip cylinder drives the flip arm to flip to the unflipped state, ready for the installation of the next nail column.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The extraction device for nail column installation provided by the present invention is provided with a flipping mechanism. When in the unflipped state, the nail column profiling hole of the profiling limit block faces upward, which is convenient for placing the nail column and applying glue on the surface of the nail column. Moreover, compared with the traditional nail column installation device, after flipping, it can be directly pressed down and pasted, which can effectively prevent the polyurethane glue from dripping everywhere and affecting the appearance of the glass.

[0027] 2. The pulling device for installing nail columns provided by the present invention is designed with a pulling motor and a contour limit block. After the installation of the nail column is completed, the pulling cylinder is retracted to drive the contour limit block upward. At this time, the nail column support still presses the nail column on the glass surface to prevent the contour limit block from driving the nail column upward when it is retracted upward, thereby improving the installation efficiency of the nail column and the product qualification rate.

[0028] 3. The flipping mechanism of the extraction device for installing a nail column provided by the present invention is also provided with a stabilizing component to prevent the flipping arm from shaking slightly, thereby further improving the installation accuracy of the nail column.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Example 1

[0037] A pulling and touching device comprises a turning mechanism, a pressing mechanism and a pulling and touching mechanism;

[0038] The flip mechanism is as follows Figure 1 Figure 2 As shown, it comprises a turning cylinder 2 mounted on a mounting base 1 and a turning arm 3 mounted on an output shaft of the turning cylinder 2 and turned accordingly;

[0039] The pressing mechanism is as follows Figure 2 , Figure 3 As shown, it includes a pressing cylinder 5 installed at the end of the flip arm 3 through a first bracket 4 and a second bracket 6 driven by the pressing cylinder 5 to move up and down; the second bracket 6 is L-shaped; a vertical right-angle side of the second bracket 6 is slidably installed on the first bracket 4 through a first slide rail slider assembly 7;

[0040] The pulling mechanism is as follows Figure 3 As shown, it includes a drawing cylinder 8 and a nail column support 9 fixedly mounted on a horizontal right-angled side of the second bracket 6, and a contour-profiling limit block 10 driven by the drawing cylinder 8; the contour-profiling limit block 10 is as shown in Figure 4 Figure 5 As shown, it includes an integrally connected sliding portion 10-1, a connecting portion 10-2 and a limiting portion 10-3; the sliding portion 10-1 is slidably connected to the second bracket 6 through a second slide rail slider assembly 11; the lower end of the nail column support 9 passes through the connecting portion 10-2 and is nested in the limiting portion 10-3.

[0041] The nail column installation process of the above-mentioned extraction device includes the following processes:

[0042] First, the flip arm 3 is in a non-flipped state. Figure 2 As shown, at this time, the nail column profiling hole of the limiting portion 10-3 faces upward, and the nail column to be installed is placed in the nail column profiling hole;

[0043] Then, start the flip cylinder 2 to flip the flip arm 3 to the flip state, at which time the nail column profiling hole faces downward (it is sucked by the cylinder to prevent it from falling). Figure 3 As shown, the pressing cylinder 5 is started to press downward, and the nail column to be installed in the nail column profiling hole is pasted on the glass. At this time, the pulling cylinder 8 is in an extended state; after the pasting is completed, the pulling cylinder 8 is retracted, driving the profiling limit block 10 upward. At this time, the nail column support member 9 still presses the nail column on the glass surface to prevent the profiling limit block 10 from driving the nail column upward when it is retracted upward;

[0044] Finally, the pressing cylinder 5 is lifted upward, and the nail column support 9 is lifted upward accordingly, leaving the nail column on the glass surface; the turning cylinder 2 drives the turning arm 3 to turn to the non-turned state, preparing for the installation of the next nail column.

[0045] Example 2

[0046] In order to ensure the stability of the flip arm 3, the flip mechanism is also provided with a stabilizing component; Figure 2 As shown, the stabilizing assembly includes a stabilizing limit plate 12 fixedly mounted on the mounting base 1, a stabilizing cylinder 13 mounted on the stabilizing limit plate 12, a pressure stabilizing member 14 mounted on the piston rod of the stabilizing cylinder 13, and a support member 15 mounted on the stabilizing limit plate 12; one end of the stabilizing limit plate 12 is fixedly connected to the mounting base 1, and the other end on which the support member 15 is mounted is located directly below the flip arm 3 (when in the flip state), and the support member 15 is also located directly below the flip arm 3 to support the flip arm 3; one end of the pressure stabilizing member 15 is mounted on the piston rod of the stabilizing cylinder 13, and the other end is located directly above the flip arm 3 (when in the flip state) to press the flip arm 3.

[0047] The support member 15 comprises a buffer and a supporting bolt. When the turning arm 3 turns over, it is first buffered by the buffer and then falls on the supporting bolt.

[0048] During the above-mentioned nail column installation process, when the flip arm 3 flips to the flip state, the stabilizing cylinder 13 is started to drive the pressure stabilizing member 14 to press the flip arm 3 downward, so that the flip arm 3 is pressed between the support member 15 and the pressure stabilizing member 14 to prevent the flip arm 3 from moving.

[0049] Example 3

[0050] As a preference, Figure 1 As shown, the mounting base 1 includes a first base 1-1, a second base 1-2 and a mounting frame 1-3; the first base 1-1 is provided with a longitudinal dovetail groove, and the second base 1-2 and the first base 1-1 are longitudinally slidably connected through the longitudinal dovetail groove; the second base 1-2 is provided with a transverse dovetail groove, and the mounting frame 13-3 and the second base 1-2 are transversely slidably connected through the transverse dovetail groove. Based on the above mechanism, the transverse and longitudinal positions of the mounting frame 1-3 can be conveniently adjusted.

[0051] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0052] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
