Description

Technical Field

[0001] The utility model belongs to the technical field of glue bonding and assembling between plastic products and suede, and particularly relates to a bonding device for pasting suede on the rear pillar of an automobile. Background Art

[0002] Nowadays, with the development of the automobile industry, consumers have higher requirements for the interior of automobiles. They are often no longer satisfied with the plastic interior and prefer the interior with a leather texture. Among them, the rear pillar trim is one of the parts of the automobile. The rear pillar trim uses plastic as the base to play a role in stable support, and then suede is bonded on its surface, which looks more beautiful and high-grade. At the same time, the price is relatively low, which is more suitable for the aesthetic and needs of the public. However, since plastic and suede are two different materials, they can only be bonded by glue. But when the rear pillar trim and suede are bonded manually, there will be situations such as difficult bonding, low precision, slow speed, and low efficiency. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a bonding device for pasting suede on the rear pillar of an automobile. First, the rear pillar is fixed on the profiling block, and the suede is fixed on the die hole of the workbench through a positioning fixture. After applying glue to the suede, the rear pillar on the profiling block is pressed down against the suede, and then pressed onto the shaping block. Finally, the completed rear pillar is ejected by the ejection assembly to complete the processing, and the effect is better than manual operation.

[0004] To achieve the above object, the technical solution adopted by the utility model is:

[0005] A bonding device for pasting suede on the rear pillar of an automobile, which is used to bond the suede on the rear pillar, includes a machine table, a support frame, a solidifying component, and a forming component. The support frame is in an inverted U shape and is detachably connected to the machine table.

[0006] The solidifying component includes a profiling block, a first cylinder, a fixed seat, and a slide rail seat. The profiling block is movably connected to the support frame and points downward. The rear pillar is detachably connected to the bottom of the profiling block. The first cylinder is connected to the top of the support frame, and the output end of the first cylinder penetrates downward through the support frame and is connected to the fixed seat. The profiling block is connected to the bottom of the fixed seat. The slide rail seat is connected to the side of the fixed seat, and the slide rail seat cooperates with the guide rail on the inner side of the support frame;

[0007] The forming assembly includes a sizing block, a workbench, a sponge, an ejection assembly, and several positioning jigs connected to the machine table. The workbench is sleeved on the sizing block. A hole larger than the outer contours of the profiling block and the sizing block is provided on the workbench, and the suede is covered on the hole. The sizing block faces upward towards the profiling block and cooperates with the profiling block. Several of the positioning jigs are distributed on the outer contour edge of the hole and point towards the hole. The sponge is arranged inside the workbench and covers the upper end surface of the sizing block. The ejection assembly includes an ejecting block and a second cylinder. A through hole is provided on the sizing block, and the ejecting block is fitted inside the through hole. The second cylinder is connected to the lower end surface of the machine table, and the output end of the second cylinder penetrates upward through the machine table and is connected to the ejecting block. A through hole larger than the outer contour of the ejecting block is provided on the sponge.

[0008] For the bonding device for pasting suede on the rear pillar of an automobile with this structure, the support frames on the machine table all play a supporting role. In order to bond the suede on the rear pillar, a sizing block that can completely fit the rear pillar surface is required to press the suede onto the rear pillar. Therefore, a sizing block is connected to the machine table for fixation. The sizing block faces upward. After pasting the suede on the lower end surface of the rear pillar and pressing it onto the sizing block, the suede can be made to fit on the rear pillar. However, this downward pressure also needs to be balanced. Therefore, a profiling block is provided. The rear pillar is detachably connected to the bottom of the profiling block, and the bottom curved surface of the profiling block fits the inner side surface of the rear pillar. Therefore, when the profiling block is pressed down, the distributed force on the rear pillar will be more uniform. Thus, the suede is evenly stressed after fitting on the rear pillar. In order to automatically press down the profiling block, press the rear pillar and the suede onto the sizing block, a first cylinder is provided. The first cylinder is fixedly connected to the support frame, and the output end of the first cylinder passes through the support frame and is connected to the profiling block. In this way, the downward pushing force of the cylinder can be used to press and extrude, so that the suede has a better pressing effect when fitting on the rear pillar. However, if only the cylinder is used to push the profiling block, the profiling block may rotate during the up and down movement, resulting in the profiling block not being aligned with the sizing block, thus causing a high defective rate during the production process. Therefore, a fixed seat is connected to the output end of the first cylinder, the profiling block is connected to the bottom of the fixed seat, and a slide rail seat is connected to the side surface of the fixed seat. The slide rail seat cooperates with the guide rail on the inner side surface of the support frame. Therefore, the profiling block will move up and down under the restriction of the slide rail seat and the guide rail and cannot rotate anymore. Therefore, the profiling block will always be aligned with the sizing block during the up and down movement, avoiding the generation of defective products caused by deviation.

[0009] The profiling block has fixed the rear column, and the shaping block is fixed on the machine table. Then, the problem to be solved is to fix the suede. Therefore, a workbench is sleeved on the shaping block, and a shaped hole larger than the outer contours of the profiling block and the shaping block is provided on the workbench. Therefore, when the profiling block presses down, it can directly pass through the shaped hole without contacting the shaped hole, cover the suede on the shaped hole, and clamp and fix it through the positioning fixture on the edge of the outer contour of the shaped hole. The suede is placed with its leather surface facing down, and the upper end surface of the suede is coated with glue. When the profiling block is pushed by the first cylinder and presses down, the rear column on the profiling block abuts against the suede and continues to move down. At this time, the suede will directly abut against the outer side wall of the shaping block. Since the surface of the suede has no protection at this time, directly abutting against the shaping block may cause wear to the suede. Therefore, a sponge is arranged inside the workbench, and the sponge covers the upper end surface of the shaping block. Therefore, with the sponge as a buffer, it can be ensured that the suede will not directly abut against the shaping block, protecting the outer surface of the suede.

[0010] To facilitate the detachment of the rear column with the suede bonded, an ejection assembly is provided. The second cylinder drives the ejector block to move up from the through hole on the shaping block, pass through the through hole on the sponge, and abut against the rear column with the suede bonded, and lift it up, so that it is convenient for workers to unload the material. The ejection assembly can be set in multiple groups, and the ejector blocks are distributed around the shaped hole, which can achieve a better effect of supporting and lifting.

[0011] Furthermore, the shaping assembly further includes a stroke limit block, and the stroke limit block is connected to the machine table and points to the slide rail seat.

[0012] Compared with the prior art, the advantages of the present utility model are as follows: Through the up and down movement of the profiling block, the rear column is driven to press down until it abuts against the suede covered on the workbench, and continues to press down until the profiling block and the shaping block are pressed together, pressing the suede onto the rear column. The sponge provided inside the workbench can be used as a buffer, which can ensure that the suede will not directly abut against the shaping block, protecting the outer surface of the suede, and the rear column with the suede bonded is lifted up by the ejection assembly for detachment, so that it is convenient for workers to unload the material.

[0019] The specific embodiments of the present utility model will be described below in conjunction with the drawings:

[0020] As Figures 1-3 shown, an adhesive device for pasting suede on the rear column of an automobile, which is used to paste the suede 1 on the rear column 2, includes a machine table 3, a support frame 4, a shaping component 5 and a forming component 6, and the support frame 4 is detachably connected to the machine table 3 in an inverted U shape.

[0021] The shaping component 5 includes a profiling block 51, a first cylinder 52, a fixed seat 53 and a slide rail seat 54. The profiling block 51 is movably connected to the support frame 4 and points downward. The rear column 2 is detachably connected to the bottom of the profiling block 51. The first cylinder 52 is connected to the top of the support frame 4. The output end of the first cylinder 52 penetrates downward through the support frame 4 and is connected to the fixed seat 53. The profiling block 51 is connected to the bottom of the fixed seat 53. The slide rail seat 54 is connected to the side of the fixed seat 53, and the slide rail seat 54 cooperates with the guide rail 41 on the inner side of the support frame 4;

[0022] The shaping component 6 includes a shaping block 61, a workbench 62, a sponge 64, an ejection component 65 and a plurality of positioning jigs 63 connected to the machine table 3. The workbench 62 is sleeved on the shaping block 61. A mold hole 621 larger than the outer contours of the profiling block 51 and the shaping block 61 is provided on the workbench 62. The suede 1 covers the mold hole 621. The shaping block 61 faces upward towards the profiling block 51 and cooperates with the profiling block 51. A plurality of the positioning jigs 63 are distributed on the edge of the outer contour of the mold hole 621 and point to the mold hole 621. The sponge 64 is arranged in the workbench 62 and covers the upper end surface of the shaping block 61. The ejection component 65 includes an ejecting block 651 and a second air cylinder 652. A through hole 611 is provided on the shaping block 61. The ejecting block 651 is fitted in the through hole 611. The second air cylinder 652 is connected to the lower end surface of the machine table 3. The output end of the second air cylinder 652 penetrates upward through the machine table 3 and is connected to the ejecting block 651. A through hole 641 larger than the outer contour of the ejecting block 651 is provided on the sponge 64.

[0023] Further, the shaping component 5 further includes a stroke limit block 55 connected to the machine table 3 and pointing to the slide rail seat 54.

[0024] The working mode of the present utility model is described as follows:

[0025] For the bonding device of suede on the rear pillar of an automobile adopting this structure, the support frames 4 on the machine table 3 all play a supporting role. In order to bond the suede 1 to the rear pillar 2, a shaping block 61 that can completely fit the surface of the rear pillar 2 is required to press the suede 1 onto the rear pillar 2. Therefore, the shaping block 61 is connected and fixed on the machine table 3, with the shaping block 61 pointing upward. After bonding the suede 1 to the lower end surface of the rear pillar 2 and pressing it onto the shaping block 61, the suede 1 can be made to fit the rear pillar 2. However, the downward pressure also needs to be balanced. Therefore, a profiling block 51 is provided, and the rear pillar 2 is detachably connected to the bottom of the profiling block 51. The bottom curved surface of the profiling block 51 fits the inner side surface of the rear pillar 2. Therefore, when the profiling block 51 presses downward, the distributed force on the rear pillar 2 will be more uniform, and thus the suede 1 will be evenly stressed after fitting the rear pillar 2. In order to automatically press down the profiling block 51 and press the rear pillar 2 and the suede 1 onto the shaping block 61, a first cylinder 52 is provided. The first cylinder 52 is fixedly connected to the support frame 4, and the output end of the first cylinder 52 passes through the support frame 4 and is connected to the profiling block 51, so that the downward pushing force of the cylinder can be used to achieve better pressing effect for the suede 1 to fit the rear pillar 2. However, if only the cylinder is used to push the profiling block 51, the profiling block 51 may rotate during the up and down movement, resulting in the profiling block 51 not being aligned with the shaping block 61, thus causing a high defective rate during the production process. Therefore, a fixing seat 53 is connected to the output end of the first cylinder 52, the profiling block 51 is connected to the bottom of the fixing seat 53, and a slide rail seat 54 is connected to the side surface of the fixing seat 53. The slide rail seat 54 cooperates with the guide rail 41 on the inner side surface of the support frame 4. Therefore, the profiling block 51 will move up and down under the restriction of the slide rail seat 54 and the guide rail 41 and cannot rotate anymore. Therefore, the profiling block 51 will always be aligned with the shaping block 61 during the up and down movement, avoiding the generation of defective products caused by deviation.

[0026] The profiling block 51 has fixed the rear column 2, and the shaping block 61 is fixed on the machine table 3. Then, the problem to be solved is to fix the suede 1. Therefore, a workbench 62 is sleeved on the shaping block 61. A shaping hole 621 larger than the outer contours of the profiling block 51 and the shaping block 61 is provided on the workbench 62. Thus, when the profiling block 51 presses down, it can directly pass through the shaping hole 621 without contacting the shaping hole 621, cover the suede 1 on the shaping hole 621, and clamp and fix it through the positioning fixture 63 on the edge of the outer contour of the shaping hole 621. The leather surface of the suede 1 is facing downwards, and the upper end surface of the suede 1 is coated with glue. When the profiling block 51 is pushed down by the first cylinder 52, the rear column 2 on the profiling block 51 abuts against the suede 1 and continues to move downwards. At this time, the suede 1 will directly abut against the outer side wall of the shaping block 61. Since the surface of the suede 1 has no protection at this time, directly abutting against the shaping block 61 may cause wear to the suede 1. Therefore, a sponge 64 is provided inside the workbench 62, and the sponge 64 covers the upper end surface of the shaping block 61. Thus, with the sponge 64 as a buffer, it can be ensured that the suede 1 does not directly abut against the shaping block 61, protecting the outer surface of the suede 1.

[0027] To facilitate the detachment of the rear column 2 with the suede 1 bonded well, an ejection assembly 65 is provided. The ejector block 651 is driven by the second cylinder 652 to move upward from the through hole 611 on the shaping block 61, pass through the through hole 641 on the sponge 64, abut against the rear column 2 with the suede 1 bonded well, and lift it upward, so as to facilitate the worker to unload the material. The ejection assembly 65 can be set in multiple groups, and the ejector blocks 651 are distributed around the shaping hole 621, which can achieve a better effect of supporting and lifting.

[0028] A stroke limit block 55 is also provided and placed on the machine table 3 and points upward to the slide rail seat 54. Therefore, when the profiling block 51 is pushed down by the first cylinder 52, the slide rail seat 54 will also move downward along the guide rail 41. The stroke of the downward movement of the slide rail seat 54 is restricted, which can prevent the profiling block 51 from being overly pressed on the shaping block 61, resulting in the suede 1 being overly pressed on the rear column 2. The effective stroke limit can ensure the quality guarantee during the production process.

[0029] The beneficial effects of the present utility model are as follows: Through the up and down movement of the profiling block 51, the rear column 2 is driven to press down until it abuts against the suede 1 covered on the workbench 62, and continues to press down until the profiling block 51 is pressed against the shaping block 61, pressing the suede 1 onto the rear column 2. The sponge 64 provided inside the workbench 62 can be used as a buffer, which can ensure that the suede 1 does not directly abut against the shaping block 61, protecting the outer surface of the suede 1, and the ejection assembly 65 is used to lift the rear column 2 with the suede 1 bonded well upward for detachment, so as to facilitate the worker to unload the material.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
