Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board production, in particular to an automatic adhesive tape attaching device. Background Art

[0002] Flexible printed circuit boards (FPCs) are manufactured using a flexible substrate, offering excellent flexibility and bendability. They are widely used in electronic products such as mobile phones, tablets, and wearable devices. One of the advantages of FPCs is their flexibility, which makes them suitable for shaping. However, shaping requires a way to fix the shape after shaping. Taping is one of the common methods used to achieve this.

[0003] Most current tape application technologies use a one-to-one approach to ensure accuracy during application. However, this approach has certain limitations when implemented:

[0004] First, when applying tape to products, some products require at least two types of tape instead of just one. In this case, a one-to-one application method is less efficient and requires longer work hours.

[0005] Secondly, because you need to stick multiple types of tape, for example, two types.

[0006] When applying one type of tape, the accuracy of the application can be guaranteed to a certain extent due to operational proficiency and familiarity with the tape. However, when applying two types of tape, due to the replacement of tapes and operational habits, even if one is relatively familiar with the two types of tape, the accuracy of the tape application may be low.

[0007] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved in this utility model. Utility Model Content

[0008] The utility model provides an automatic adhesive tape attaching device, aiming to solve the technical problems raised in the above background technology.

[0009] To achieve the above-mentioned object, the technical solution adopted by the present invention is: an automatic tape attaching device, which is arranged on the upper surface of a work cabinet and is used to tear off the attaching tape adhered to the surface of the base tape and attach it to the surface of the product. The automatic attaching device includes a carrier, a streamline, a discharge mechanism, a lifting mechanism, a lower detection mechanism, an upper detection mechanism, and a four-axis attaching mechanism;

[0010] The streamline is arranged on the upper surface of the work cabinet, and has a plurality of pressing stations arranged in sequence along the flow direction of the streamline. The carrier is transferred to the plurality of pressing stations in sequence through the streamline, and the carrier is provided with a plurality of carrying positions for carrying the same or different types of products, and each carrying position corresponds to each pressing station one by one;

[0011] The unloading mechanism includes a plurality of unloading racks, all of which are arranged on the upper surface of the work cabinet. The unloading racks have an unloading port for unloading the corresponding adhesive tape for the product, and the unloading port on each unloading rack is respectively arranged in a one-to-one correspondence with each laminating station;

[0012] The lifting mechanism is positioned and connected to the streamline and is arranged corresponding to the pressing station. The movable ends of the lifting mechanism are configured to act on both sides of the lower surface of the carrier. The movable ends of the lifting mechanism are used to push the carrier upward to form a flow channel between the carrier and the streamline surface.

[0013] The four-axis attachment mechanism includes a horizontal transfer frame, a lifting transfer mechanism and a self-rotating transfer frame;

[0014] The horizontal transfer frame is arranged above the streamline through a bracket, and the self-rotating transfer frame is slidably arranged on the horizontal transfer frame; the self-rotating transfer frame slides in a direction parallel to or perpendicular to the streamline through the horizontal transfer frame;

[0015] The lower end of the self-rotating transfer frame is a rotating end and is positioned and connected to the lifting transfer mechanism. The lifting transfer mechanism can rotate around a direction perpendicular to the horizontal transfer frame with the rotating end as the rotation center. The lower end of the lifting transfer mechanism is provided with an adsorption head for sucking up the attachment tape and pressing the attachment tape onto the corresponding product surface;

[0016] The lower detection mechanism is positioned and connected to one side of the streamline, and the detection head of the lower detection mechanism faces the adsorption head to detect the state of the attachment tape being separated from its base tape; the upper detection mechanism is arranged above the four-axis attachment mechanism, and the detection head of the upper detection mechanism also faces the adsorption head to detect the attachment position of the attachment tape on the product.

[0017] According to a further technical solution, the lifting and transporting mechanism includes a connecting box cover, the top end of which is a closed end and is positioned and connected to the rotating end of the self-rotating transport frame;

[0018] The lower end of the connecting box cover is an open end, and a lifting structure is fixedly arranged inside the connecting box cover. The movable end of the lifting structure is provided with a pressure sensor, and the detection end of the pressure sensor is positioned and connected to the adsorption head to realize the detection of the pressure applied to the attachment tape.

[0019] In the above scheme, the top of the connecting box cover is a closed end, the bottom end is an open end, and the surrounding side can also be a closed side. This is a preferred way, but the top can also be open, as long as the top can be positioned and connected with the rotating end of the self-rotating transport frame. Secondly, the surrounding side can also be as follows Figure 4 As shown, two openings are provided.

[0020] According to a further technical solution, the lower detection mechanism is a lower detection camera arranged between the streamline and the material discharging rack, and the lower detection camera is positioned and connected to the side of the streamline.

[0021] The detection head of the lower detection mechanism is the camera head of the lower detection camera.

[0022] According to a further technical solution, the upper detection mechanism includes a first fixing frame, a second fixing frame, a positioning frame and an upper detection camera;

[0023] The first fixing brackets are provided with two and are positioned and connected to the upper end of the bracket, and each of the first fixing brackets is provided with the upper detection camera;

[0024] The second fixing frame is connected to the upper end of the bracket through the positioning frame, and the upper detection camera is also provided on the second fixing frame;

[0025] The second fixing frame is located between the two first fixing frames.

[0026] With this design, the self-rotating transfer frame can slide in a direction parallel to or perpendicular to the streamline by sliding horizontally or vertically on the horizontal transfer frame.

[0027] In a further technical solution, the bottom of the carrier has an abutment surface and lifting mating surfaces arranged on both sides of the abutment surface, and there is a set gap between the lifting mating surface and the streamline;

[0028] When the carrier flows on the streamline, the abutment surface is configured to abut against the upper surface on the streamline;

[0029] The two lifting matching surfaces are respectively arranged corresponding to the movable ends of the lifting mechanisms acting on both sides of the lower surface of the carrier.

[0030] With this design, when the movable end of the lifting mechanism lifts the carrier, the movable end can quickly lift the carrier by setting the interval without affecting the abutting surface.

[0031] If no interval is set, a hole must be opened on the streamline (or the length of the vehicle must greatly exceed the width of the streamline) to achieve the purpose of lifting. This will affect the subsequent flow of vehicles and fail to achieve the purpose of ensuring that the streamline is unobstructed and not accumulated.

[0032] According to a further technical solution, the streamline comprises two tracks positioned and connected to the upper surface of the work cabinet. The tracks may be belts.

[0033] According to a further technical solution, the horizontal transfer frame includes two first transfer guide rails arranged above the flow line through the bracket, a second transfer guide rail is provided between the two first transfer guide rails, and the self-rotating transfer frame is slidably arranged on the second transfer guide rail;

[0034] When viewed from the angle directly above the lamination station, the first transfer guide rail is perpendicular to the flow line;

[0035] The second transfer guide rail is parallel to the flow line.

[0036] The two first transfer guide rails and the second transfer guide rail can be combined to form an I-shaped structure.

[0038] As used herein, “connected” or “positioned” may refer to two or more components or devices being in direct or indirect physical contact with each other, or may refer to two or more components or devices operating or moving with each other.

[0039] The terms “include”, “including”, “have”, etc. used in this document are open-ended terms, meaning including but not limited to.

[0040] Unless otherwise noted, the terms used herein generally have their ordinary meanings in the art, in the context of the present invention, and in the specific context. Certain terms used to describe the present invention are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art regarding the description of the present invention.

[0041] The terms "front", "back", "up", "down", "left", "right", etc. used in this article are all directional terms. In this case, they are only used to illustrate the positional relationship between the various structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0042] The working principle and advantages of this utility model are as follows:

[0043] The utility model can realize the simultaneous attachment operation of a large number of different types of products at multiple stations through the cooperation of multiple pressing stations, multiple bearing stations and multiple material discharging racks. Compared with a single one-to-one attachment, it is more efficient and saves work time.

[0044] Secondly, in order to ensure that the streamline is unobstructed and there is no accumulation during attachment, the carrier is pushed up by the lifting mechanism to form a flow channel between the carrier and the streamline surface, so that the lower streamline can transport the remaining carriers to the lower station for attachment.

[0045] Specifically, multiple carrying positions for products of the same or different types are placed directly on the carrier. For example, two types are placed, four of each type. In this way, there are two pressing stations, a carrying position and two material placement racks.

[0046] Afterwards, the streamline carries the carrier to move on the two lamination stations. When the carrier moves to the first lamination station, at this time, since the discharge port on the first discharge rack corresponds to the first lamination station, the suction head is driven to the top of the attachment tape on the first discharge rack through the horizontal transfer rack. Then, the lifting and transfer mechanism carries the suction head down to suck up the attachment tape. Subsequently, the attachment tape is driven to the top of the product to be attached through the horizontal transfer rack (in this process, the detection head of the lower detection mechanism will detect the state of the attachment tape detached from its base tape. If NG, the material will be thrown away. If OK, it will move to the top of the product to be attached), and the attachment operation is realized by lowering the suction head through the lifting and transfer mechanism.

[0047] During the attachment process, the detection head of the upper detection mechanism will detect the attachment position of the adhesive tape on the product. After the attachment is completed, the adsorption head returns to the adhesive tape picking position. During the whole process, the adhesive tape can be accurately positioned to reduce the damage rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0064] Embodiment: The present invention will be clearly illustrated below with drawings and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0065] The terms used herein are for describing specific embodiments only and are not intended to be limiting of the present invention. Singular forms such as "a," "the," "this," "this," and "the" as used herein also include plural forms.

[0066] See attached Figures 1-14As shown, an automatic tape attaching device is arranged on the upper surface of a work cabinet 1, and is used to tear off the attaching tape adhered to the surface of the base tape and attach it to the surface of the product. It is characterized in that: the automatic attaching device includes a carrier 2, a streamline 3, a discharge mechanism 4, a lifting mechanism 5, a lower detection mechanism 6, an upper detection mechanism 7 and a four-axis attaching mechanism 8;

[0067] The streamline 3 is arranged on the upper surface of the work cabinet 1, and has a plurality of pressing stations 27 arranged in sequence along the flow direction of the streamline 3. The carrier 2 is transferred to the plurality of pressing stations 27 in sequence through the streamline 3, and the carrier 2 is provided with a plurality of carrying positions 9 for carrying the same or different types of products, and each carrying position 9 corresponds to each pressing station 27 one by one.

[0068] The unloading mechanism 4 includes a plurality of unloading racks 10, all of which are arranged on the upper surface of the work cabinet 1. The unloading rack 10 has a discharge port 26 for discharging the corresponding adhesive tape for the product. The discharge port 26 on each unloading rack 10 is respectively arranged in a one-to-one correspondence with each laminating station 27.

[0069] The lifting mechanism 5 is positioned and connected to the streamline 3 and is provided corresponding to the pressing station 27. The movable ends of the lifting mechanism 5 are configured to act on both sides of the lower surface of the carrier 2. The movable ends of the lifting mechanism 5 are used to push the carrier 2 upward to form a flow channel between the carrier 2 and the surface of the streamline 3.

[0070] The four-axis attachment mechanism 8 includes a horizontal transfer frame 11, a lifting transfer mechanism 12 and a rotation transfer frame 13;

[0071] The horizontal transfer frame 11 is arranged above the flow line 3 through a bracket 14, and the self-rotating transfer frame 13 is slidably arranged on the horizontal transfer frame 11; the self-rotating transfer frame 13 slides in a direction parallel to or perpendicular to the flow line 3 through the horizontal transfer frame 11;

[0072] The lower end of the self-rotating transfer frame 13 is a rotating end and is positioned and connected to the lifting transfer mechanism 12. The lifting transfer mechanism 12 can rotate around the direction perpendicular to the horizontal transfer frame 11 with the rotating end as the rotation center. The lower end of the lifting transfer mechanism 12 is provided with an adsorption head 15 for sucking up the adhesive tape and pressing the adhesive tape onto the corresponding product surface.

[0073] The lower detection mechanism 6 is positioned and connected to one side of the streamline 3, and the detection head of the lower detection mechanism 6 is facing the adsorption head 15, so as to detect the state of the attachment tape being separated from its base tape; the upper detection mechanism 7 is arranged above the four-axis attachment mechanism 8, and the detection head of the upper detection mechanism 7 is also facing the adsorption head 15, so as to detect the attachment position of the attachment tape on the product.

[0074] The present invention can realize the simultaneous attachment operation of multiple products of different types at multiple stations through the cooperation of multiple pressing stations 27, multiple supporting stations 9 and multiple material discharging racks 10. Compared with the single one-to-one attachment in the prior art, it is more efficient and saves work time.

[0075] Secondly, in order to ensure that the streamline is unobstructed and not accumulated during attachment, the carrier 2 is pushed up by the lifting mechanism 5 to form a flow channel between the carrier 2 and the surface of the streamline 3, so that the lower streamline can transport the remaining carriers 2 to the lower station for attachment.

[0076] Specifically, multiple carrying positions 9 for products of the same or different types are placed directly on the carrier 2 , for example, two types, four of each type, are placed. In this way, there are two pressing stations 27 , 8 carrying positions 9 and two unloading racks 10 .

[0077] Afterwards, the streamline 3 carries the carrier 2 to move on the two laminating stations 27. When the carrier 2 moves to the first laminating station 27, at this time, since the discharge port 26 on the first discharge rack 10 corresponds to the first laminating station 27, the adsorption head 15 is driven to the top of the attachment tape on the first discharge rack 10 through the horizontal transfer rack 11. Then, the lifting and transfer mechanism 12 carries the adsorption head 15 down to suck up the attachment tape. Subsequently, the attachment tape is driven to the top of the product to be attached through the horizontal transfer rack 11 (in this process, the detection head of the lower detection mechanism 6 will detect the state of the attachment tape detached from its base tape. If NG, it will perform the material throwing action. If OK, it will move to the top of the product to be attached), and the attachment operation is realized by lowering the adsorption head 15 through the lifting and transfer mechanism 12.

[0078] During attachment, the detection head of the upper detection mechanism 7 will detect the attachment position of the attachment tape on the product. After attachment, the adsorption head 15 returns to the attachment tape taking position. During the whole process, the attachment tape can be accurately positioned to reduce the damage rate.

[0079] In the above scheme, based on the flow direction of the streamline 3, the horizontal transfer rack 11 can make the adsorption head slide in a direction parallel or perpendicular to the streamline 3, the rotating transfer rack 13 can make the adsorption head rotate with the height direction of the streamline 3 as the rotation axis, and the lifting transfer mechanism 12 can move the adsorption head up and down. These three mechanisms work together to realize operations in four directions.

[0080] The specific structure of the self-rotating transport frame 13 can be referred to Figure 4 , which includes a motor, and a mounting block is set on the side of the motor to be positioned and linked to the horizontal transfer rack 11.

[0081] In some specific embodiments, the lifting and transporting mechanism 12 includes a connecting box cover 16, the top end of which is a closed end and is positioned and connected to the rotating end of the rotating transport frame 13;

[0082] The lower end of the connecting box cover 16 is an open end, and a lifting structure 17 is fixedly provided inside the connecting box cover 16. A pressure sensor 18 is provided at the movable end of the lifting structure 17. The detection end of the pressure sensor 18 is positioned and connected to the adsorption head 15 to realize the detection of the pressure applied to the attachment tape.

[0083] In the above scheme, the top of the connecting box cover 16 is a closed end, the bottom end is an open end, and the peripheral side can also be a closed side. This is a preferred way, but the top can also be open, as long as the top can be positioned and connected with the rotating end of the rotating transport frame 13. Secondly, the peripheral side can also be as follows. Figure 4 As shown, two openings are provided.

[0084] The lifting structure 17 can be selected from a cylinder, an electric push rod, a screw sleeve mechanism, etc., and an up and down telescopic cylinder can be selected here.

[0085] For example, Figure 5 In order to ensure that the adsorption head 15 does not shake when it moves up and down, a guide strip is set on the edge of the adsorption head 15, and a guide slide is set on the side of the connecting box cover 16. The guide slide and the guide strip are slidably arranged, so that when the adsorption head 15 moves up and down, the coordination between the guide slide and the guide strip can prevent the adsorption head 15 from shaking.

[0086] The adsorption head 15 is composed of a plurality of suction heads and a washing head fixing plate for fixing a plurality of washing heads.

[0087] In order to realize the lifting and lowering operation of the adsorption head 15, specifically, the adsorption head 15 is guided to descend through the lifting structure 17 until the adsorption head 15 is pressed on the attachment tape. At this time, the pressure sensor 18 will detect the pressure applied to the attachment tape to prevent the situation where the components cannot be adsorbed or are damaged.

[0088] Afterwards, the lifting structure 17 rises to tear off the adhesive tape adhered to the surface of the base tape.

[0089] Afterwards, the self-rotating transfer frame 13 rotates with the adsorption head 15 to a certain angle so that the adhesive tape can be accurately aligned with the product surface.

[0090] In some specific embodiments, the lower detection mechanism 6 is a lower detection camera disposed between the streamline 3 and the material placement rack 10 , and the lower detection camera is positioned and connected to the side of the streamline 3 .

[0091] The lower detection camera is mainly used to detect the state of the adhesive tape being separated from its base tape (the adhesive tape and the base tape are not drawn in the figure, as it is the prior art and will not be described in detail. For ease of understanding, for example, the base tape is a wound cylindrical film with multiple adhesive tapes attached to the film).

[0092] In some specific embodiments, the upper detection mechanism 7 includes a first fixing frame 19, a second fixing frame 20, a positioning frame 21 and an upper detection camera 22;

[0093] The first fixing brackets 19 are provided with two and are positioned and connected to the upper end of the bracket 14 , and each of the first fixing brackets 19 is provided with the upper detection camera 22 ;

[0094] The second fixing frame 20 is connected to the upper end of the bracket 14 through the positioning frame 21, and the upper detection camera 22 is also provided on the second fixing frame 20;

[0095] The second fixing frame 20 is located between the two first fixing frames 19 .

[0096] The upper detection mechanism 7 is used to detect the attachment position of the attachment tape on the product. Specifically, when the attachment tape is attached to the product, the upper detection camera 22 on the first fixing frame 19 and the upper detection camera 22 on the second fixing frame 20 will take real-time photos. The working principle can refer to the industrial CCD camera.

[0097] In some specific embodiments, the bottom of the carrier 2 has an abutment surface 28 and lifting mating surfaces 29 provided on both sides of the abutment surface 28 , and a set gap exists between the lifting mating surface 29 and the streamline 3 ;

[0098] When the carrier 2 flows on the streamline 3 , the abutment surface 28 is configured to abut against the upper surface of the streamline 3 ;

[0099] The two lifting matching surfaces 29 are respectively arranged corresponding to the movable ends of the lifting mechanism 5 acting on both sides of the lower surface of the carrier 2.

[0100] Please refer to Figure 14 The abutment surface 28 abuts against the upper surface of the streamline 3, and the edge of the lifting matching surface 29 corresponds to the movable end of the lifting mechanism 5. At the same time, after the movable end of the lifting mechanism 5 lifts the carrier 2, there is a certain space between the side of the movable end of the lifting mechanism 5 and the side of the streamline 3.

[0101] With this design, when the movable end of the lifting mechanism 5 lifts the carrier 2 , the movable end of the lifting mechanism 5 can quickly lift the carrier 2 by setting the interval without affecting the abutting surface 28 .

[0102] If no interval is set, a hole must be opened on the streamline 3 (or the length of the carrier 2 greatly exceeds the width of the streamline 3) to achieve the purpose of lifting. This will affect the subsequent flow of the carrier 2 and fail to achieve the purpose of ensuring that the streamline 3 is unobstructed and not accumulated.

[0103] In some specific embodiments, the flow line 3 includes two rails 23 positioned and connected to the upper surface of the work cabinet 1 .

[0104] The track 23 is selected to be a belt.

[0105] In some specific embodiments, the horizontal transfer rack 11 includes two first transfer rails 24 disposed above the flow line 3 through the bracket 14, a second transfer rail 25 is disposed between the two first transfer rails 24, and the self-rotating transfer rack 13 is slidably disposed on the second transfer rail 25;

[0106] When viewed from the angle directly above the pressing station 27 , the first transfer guide rail 24 is perpendicular to the flow line 3 ;

[0107] The second transfer guide rail 25 is parallel to the flow line 3 .

[0108] The two first transfer guide rails 24 and the second transfer guide rail 25 can be combined to form an I-shaped structure. During operation, the two first transfer guide rails 24 move the second transfer guide rails 25 and the rotating transfer frame 13, so that the adsorption head 15 can move in a direction perpendicular to the streamline 3. When the adsorption head 15 moves to the appropriate position, the second transfer guide rail 25 moves with the rotating transfer frame 13, so that the adsorption head 15 can move in a direction parallel to the streamline 3.

[0109] Working principle: The utility model can realize the simultaneous attachment operation of multiple types of products at multiple stations through the cooperation of multiple pressing stations 27, multiple bearing stations 9 and multiple material racks 10. Compared with a single one-to-one attachment, it is more efficient and saves work time.

[0110] Secondly, in order to ensure that the streamline is unobstructed and not accumulated during attachment, the carrier 2 is pushed up by the lifting mechanism 5 to form a flow channel between the carrier 2 and the surface of the streamline 3, so that the lower streamline can transport the remaining carriers 2 to the lower station for attachment.

[0111] Specifically, multiple carrying positions 9 for the same or different types of products are placed directly on the carrier 2. For example, two types of products are placed, four of each type. In this way, there are two pressing stations 27, eight carrying positions 9 and two unloading racks 10. Figure 1 .

[0112] Afterwards, the streamline 3 carries the carrier 2 to move on the two laminating stations 27. When the carrier 2 moves to the first laminating station 27, at this time, since the discharge port 26 on the first discharge rack 10 corresponds to the first laminating station 27, the adsorption head 15 is driven to the top of the attachment tape on the first discharge rack 10 through the horizontal transfer rack 11. Then, the lifting and transfer mechanism 12 carries the adsorption head 15 down to suck up the attachment tape. Subsequently, the attachment tape is driven to the top of the product to be attached through the horizontal transfer rack 11 (in this process, the detection head of the lower detection mechanism 6 will detect the state of the attachment tape detached from its base tape. If NG, it will perform the material throwing action. If OK, it will move to the top of the product to be attached), and the attachment operation is realized by lowering the adsorption head 15 through the lifting and transfer mechanism 12.

[0113] During attachment, the detection head of the upper detection mechanism 7 will detect the attachment position of the attachment tape on the product. After attachment, the adsorption head 15 returns to the attachment tape taking position. During the whole process, the attachment tape can be accurately positioned to reduce the damage rate.

[0114] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
