Description

Technical Field

[0001] The present invention relates to the field of double-sided adhesive roller pasting, and particularly to a double-sided adhesive roller pasting machine. Background Art

[0002] As disclosed in the Chinese Utility Model Patent Publication No. CN 206569801 U, a lamp strip pasting device is disclosed, which includes a transmission mechanism and a pasting mechanism arranged on a frame. The pasting mechanism includes a tape reel and a pressure roller. The lamp strip is placed on the transmission mechanism, and the tape is attached to the lamp strip under the action of the pressure roller. The pressure roller and the transmission mechanism are synchronously driven to achieve the feeding function. The lamp strip is pasted during movement, and at this time, the friction force is mainly relied on to prevent the lamp strip from slipping. However, for lamp strips with lighter weight and smaller bottom area, such as those with an arc-shaped bottom, the friction force provided by the conveyor belt is limited. When the reaction force provided by the double-sided adhesive during pasting is greater than the friction force provided by the conveyor belt, the lamp strip will not move with the conveyor belt, which will affect the overall pasting process and cause the failure of the cyclic pasting process. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-sided adhesive roller pasting machine, which can keep the workpiece stationary and then perform roller pasting on the workpiece. For workpieces with light weight and small bottom area, the workpiece is horizontally restricted at this time to limit its upward movement in the horizontal direction. When the pasting force during roller pasting is less than the horizontal binding force, the movement of the workpiece during roller pasting can be avoided. The present invention can make this process form a cycle, which not only ensures the stability of pasting but also ensures the pasting efficiency.

[0004] To achieve the above purpose, a double-sided adhesive roller pasting machine is adopted, which includes:

[0005] A feeding window, which is used to connect the feeding position;

[0006] A material taking window, which is opposite to the feeding window and is used to connect the material taking position;

[0007] A lower layer linear guide rail assembly, which is arranged between the feeding window and the material taking window. The end near the feeding window is the feeding position, and the end near the material taking window is the material taking position;

[0008] A lower layer working position tray assembly, which is used to provide the first working position and is arranged on the lower layer linear guide rail assembly;

[0009] A lower layer linear module, which is parallel to the lower layer linear guide rail assembly and is arranged under the lower layer working position tray assembly to drive the lower layer working position tray assembly to translate;

[0010] The upper linear guide rail assembly is parallel to the lower linear guide rail assembly, is arranged on the side of the lower linear guide rail assembly and the lower station pallet assembly, and is higher than the lower linear guide rail assembly and the lower station pallet assembly;

[0011] The upper station pallet assembly is used to provide a second station and is arranged on the upper linear guide rail assembly. The upper station pallet assembly is higher than the lower linear guide rail assembly and the lower station pallet assembly;

[0012] The upper linear module is parallel to the upper linear guide rail assembly, is arranged on the side of the lower linear guide rail assembly and the lower station pallet assembly, and under the upper station pallet assembly, and is used to drive the upper station pallet assembly to translate;

[0013] The glue pasting assembly is used to perform the double-sided adhesive roller pasting operation. The lower part thereof is the glue pasting position. The glue pasting assembly is arranged above the upper station pallet assembly and the upper linear guide rail assembly;

[0014] The X-axis parallel movement assembly provides a translation track for the glue pasting assembly and is used to drive the glue pasting assembly to roll and paste double-sided adhesive on the workpiece. The double-sided adhesive is rolled from one end to the other end along the upper surface of the workpiece.

[0015] With such a structure, through the reciprocating movement of the lower station pallet assembly and the upper station pallet assembly, a cyclic glue pasting queue is formed. Moreover, the translation direction of the workpiece is different from the glue pasting direction of the double-sided adhesive. The two processes are independent of each other and do not occur simultaneously, which is beneficial to ensuring the stability of the glue pasting process and the cyclic process.

[0016] As a further improvement of the double-sided adhesive roller pasting machine, the workpiece is a light bar or a light strip.

[0017] As a further improvement of the double-sided adhesive roller pasting machine, the glue pasting assembly includes: a Z-axis module movement assembly and a glue pasting module;

[0018] The Z-axis module movement assembly includes:

[0045] The free mounting cylinder is arranged behind the cutting baffle and is used to drive the cutting baffle to move;

[0046] Differential head, which is used to adjust the position of the tool holder, thereby adjusting the position of the blade;

[0047] Cutting limit plate, which is vertically fixed to the reinforcing plate;

[0048] Glue roller assembly, which is arranged on the lower side of the cutting limit plate and is used for roller pasting double-sided tape.

[0049] With such a structure, the glue film of the double-sided tape can be pre-cut, which is convenient for the automatic disconnection of the glue film of the double-sided tape after the subsequent roller pasting is completed.

[0057] The material feeding window and the material taking window are respectively opened on the front and back opposite sides of the profile protection cover assembly.

[0058] With such a structure, it is beneficial to protect the entire cyclic glue pasting process.

[0070] A second rotating shaft, both ends of which are respectively mounted on the two sides of the material receiving and traction motor board. After the base paper is clamped and tractioned by the cross knurled wheel and the rubber-coated wheel, it then winds around the second rotating shaft and falls onto the slope of the waste guide plate.

[0071] Adopting such a structure is beneficial to the stable traction and recycling of the base paper.

[0072] As a further improvement of the double-sided adhesive roller pasting machine, safety light curtains are provided on the first side column assembly and the second side column assembly.

[0075] A module bottom plate, both ends of which are respectively mounted on the first side column assembly and the second side column assembly;

[0076] An X-axis linear module, which is used to drive the adhesive pasting assembly to translate and is arranged along the axial direction of the module bottom plate.

[0077] Adopting such a structure is beneficial to driving the adhesive pasting assembly to translate along the X-axis.

[0078] As a further improvement of the double-sided adhesive roller pasting machine, the first working station and the second working station are distributed with working stations adapted to the workpieces, and are equipped with vacuum suction cups to adsorb the workpieces, so that the workpieces and the working stations are in a relatively static state.

[0079] The present invention can keep the workpiece under static conditions and then perform roller pasting on the workpiece. At this time, the workpiece is horizontally constrained to limit its upward movement. When roller pasting, the pasting force is less than the horizontal binding force, thus avoiding the movement of the workpiece during roller pasting. The present invention can make this process form a cycle, which not only ensures the stability of adhesive pasting but also ensures the efficiency of adhesive pasting.

Detailed implementation manners

[0091] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0092] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention; the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; in addition, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0093] Embodiment 1

[0094] A double-sided adhesive roller pasting method specifically includes the following steps:

[0095] Place the workpiece to be roller-pasted in the first station, restrict its horizontal movement, make the workpiece relatively stationary with respect to the first station, and translate the first station from the feeding position to the pasting position directly below the double-sided adhesive.

[0096] When performing the roller pasting operation, roll the double-sided adhesive from one end to the other end along the upper surface of the workpiece.

[0097] After the workpiece is roller-pasted, the first station can be translated to the picking position. When picking up the workpiece, move the workpiece upward to separate it from the first station. The pasting position is located between the feeding position and the picking position. After the workpiece on the first station is taken away, the first station can be translated back to the pasting position. Thus, a pasting process for circulation is formed.

[0098] Enable another second station with a height interval to repeat the pasting process of the first station, but the second station can only be translated to the position left by the first station when the first station leaves the corresponding position. Thus, a pasting queue for circulation is formed.

[0099] In this embodiment, the workpiece is a light bar or a light strip.

[0100] In this embodiment, before the double-sided adhesive is roller-pasted, first remove the lower base paper, retain the middle layer adhesive film and the upper base paper, pull the upper base paper, and roll the middle layer adhesive film onto the workpiece to complete the separation of the upper base paper and the middle layer adhesive film.

[0101] Removing the lower base paper in advance can facilitate the subsequent processes. In this way, after the upper base paper is recycled, only the middle layer adhesive film remains, which is convenient for immediately carrying out the subsequent processes without the need to tear the base paper again.

[0102] In this embodiment, the middle layer adhesive film is pre-cut to a fixed length so that the length of each cut section matches the length of the workpiece. Then, during roller pasting, each cut position serves as the starting and ending roller pasting positions, so that after the adhesive film is roller pasted to the workpiece, it can be automatically separated.

[0103] In this way, after the adhesive film is roller pasted, it does not need to be cut again, and the adhesive film can be automatically disconnected and separated from the workpiece.

[0104] In this embodiment, when cutting the adhesive film, it is only necessary to cut horizontally to the thickness of the adhesive film without cutting the upper base paper.

[0105] In this way, the roller pasting length can be predetermined in advance, and the traction of the upper base paper can be ensured to be continuous.

[0106] In this embodiment, the adhesive film is pressed against the blade in a way of pushing the upper base paper flat to complete the cutting. During the flat pushing process, the cutting path of the blade only passes through the adhesive film and not through the upper base paper.

[0107] In this way, it is beneficial for the blade to cut the adhesive film without damaging the base paper.

[0108] In this embodiment, the traction form of the double-sided adhesive is intermittent, and when the double-sided adhesive is roller pasted, the traction of the upper base paper is stopped.

[0109] In this way, when the double-sided adhesive is roller pasted, it will not be misaligned.

[0110] In this embodiment, when the double-sided adhesive is roller pasted, the upper base paper at the traction end is pressed tightly.

[0111] In this way, when the double-sided adhesive is roller pasted, it is not easy to slip off.

[0112] In this embodiment, when the double-sided adhesive is roller pasted, multiple groups can be roller pasted simultaneously.

[0113] In this way, it is beneficial to improve the roller pasting efficiency.

[0114] In this embodiment, the double-sided adhesive is in a tensioned state when roller pasted.

[0115] In this way, the tensioned state makes the roller pasting of the double-sided adhesive more uniform.

After the bottom paper is clamped and pulled by the cross-knurled wheel 1603 and the rubber-coated wheel 1609, it then winds around the second rotating shaft 1611 and falls onto the slope of the waste guide plate 1610.

[0184] Adopting such a structure is beneficial to the stable traction and recovery of the bottom paper.

[0185] In this embodiment, safety light curtains 1700 are provided on the first side column assembly 1300 and the second side column assembly 1400.

[0191] In this embodiment, station slots 301 adapted to the workpieces are distributed on the first station and the second station, and vacuum suction cups 302 are provided to adsorb the workpieces, so that the workpieces and the station slots 301 are in a relatively static state.

[0192] In this embodiment, the rotatable connection method can be completed by setting appropriate bearings.

[0193] This embodiment can keep the workpiece under static conditions and then perform roller pasting on the workpiece. At this time, the workpiece is horizontally constrained to limit its upward movement. When roller pasting, the sticking force is less than the horizontal binding force, thus avoiding the movement of the workpiece during roller pasting. The present invention can make this process form a cycle, not only ensuring the stability of glue pasting but also ensuring the efficiency of glue pasting.

[0194] Embodiment 3

[0195] A method for fixed-length roller pasting of double-sided tape specifically includes the following steps:

[0196] Remove the bottom paper of the double-sided tape in advance, and retain the upper bottom paper and the middle layer of glue film.

[0197] Cut and segment the middle layer of glue film to a fixed length, and then perform roller pasting on the workpiece. When cutting, only cut the glue film without cutting the upper bottom paper, so that when roller pasting subsequently, the middle layer of glue film at the cut position can automatically break, while the upper bottom paper remains continuous for traction.

[0198] In this way, the upper bottom paper remains continuous all the time, which is beneficial for traction and recycling. After the middle layer of glue film is cut, it can automatically break and not stick after each roller pasting.

[0199] In this embodiment, the workpiece is a light bar or a light strip.

[0200] In this embodiment, the upper bottom paper is kept in an intermittent traction state, stops traction during cutting and roller pasting, and continues traction after cutting and roller pasting.

[0201] In this way, it can prevent dislocation and slippage and ensure the accuracy of cutting and roller pasting.

[0202] In this embodiment, the double-sided tape is under a clamping pressure condition and then cut.

[0203] In this way, when the double-sided tape is in a clamped state, it will not be too loose, which is beneficial for stable cutting and ensures the cutting quality.

[0204] In this embodiment, the length of the fixed-length segmentation is the same as the length of the workpiece to be roller pasted.

[0205] In this way, after each workpiece is roller pasted, the glue film on it can automatically break.

[0206] In this embodiment, during cutting, keep the cutting edge stationary and make the middle layer of glue film move towards the cutting edge for cutting.

[0207] In this way, it is beneficial to prevent the upper bottom paper from being cut off.

[0208] In this embodiment, the position of the cutting edge is adjusted by a differential head.

[0209] In this way, the micrometer head is convenient for fine adjustment.

[0210] In this embodiment, the double-sided tape is laterally pushed in a manner driven by air pressure.

[0211] In this way, the gradient effect of the air pressure push is better.

[0212] In this embodiment, the cutting edge is made to closely adhere to the middle layer adhesive film of the double-sided tape in advance, and the double-sided tape is moved towards the cutting edge by a distance equal to the thickness of the middle layer adhesive film, so that the cutting edge only cuts the adhesive film without cutting the upper base paper.

[0213] In this way, the cutting edge only cuts the adhesive film without damaging the upper base paper.

[0214] In this embodiment, multiple groups can be cut simultaneously when cutting the double-sided tape.
