Description

Technical Field

[0001] This application relates to the field of automation, and more specifically to an adhesive application assembly and bonding device. Background Technology

[0002] Currently, most copper sheet bonding operations are performed manually. (Refer to...) Figure 1 and Figure 2 For example, if it is necessary to bond the first component 1 and the second component 2 together with the adhesive 3c, the first component 1 can be placed on the fixture, the adhesive 3c can be attached to the surface of the first component 1, and finally the second component 2 can be pressed onto the adhesive 3c.

[0003] However, the reliability of manual adhesive application gradually decreases with accumulated working hours. Furthermore, the adhesive surfaces are covered with a base film and a cover film, respectively, which need to be peeled off before use. The peeled base film and cover film often carry static electricity, requiring significant manpower and time to collect. Moreover, it is difficult to maintain consistent pressure during manual pressing, and the force distribution is also difficult to ensure uniformity, making it difficult to reliably bond the first and second components. Summary of the Invention

[0004] This application is made in view of the state of the prior art described above. The object of this application is to provide an adhesive assembly and bonding device that can overcome at least one of the disadvantages described in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution.

[0006] This application provides an adhesive application assembly for attaching the adhesive body of an adhesive tape to a target component. The adhesive tape includes a cover film, a base film, and the adhesive body, with the adhesive body positioned between the cover film and the base film. The adhesive application assembly includes: a supply roller for holding the adhesive tape, the supply roller being rotatable to release the adhesive tape wound on the supply roller; and a separation mechanism including a first guide roller, a second guide roller, and a third guide roller, the rotation axes of the first guide roller, the second guide roller, and the third guide roller being parallel to each other and offset, thereby arranging the first guide roller, the second guide roller, and the third guide roller in a triangular configuration. The tape passes around the first guide roller, the overlay is guided by the first guide roller to the second guide roller, and the combination of the base film and the adhesive is guided by the first guide roller to the third guide roller, such that the tape separates the overlay and the combination at the first guide roller; an adhesive roller is used to roll the adhesive on the target component, such that the adhesive separates from the base film and adheres to the target component; a first receiving shaft is rotatable to wind the separated overlay around the first receiving shaft; and a second receiving shaft is rotatable to wind the separated base film around the second receiving shaft.

[0007] In an alternative embodiment, a detection roller and a position sensor are also included, the detection roller being used to tension the separated film, and the position sensor being configured to be triggered when the detection roller is in a target position.

[0008] In another alternative embodiment, the position sensor includes a first position sensor and a second position sensor, wherein the first position sensor is configured to be triggered when the detection roller is located at a first target position, and the second position sensor is configured to be triggered when the detection roller is located at a second target position different from the first target position.

[0009] In another alternative embodiment, the separated film is configured to bear a first tension force when the detection roller is in the first target position, and to bear a second tension force different from the first tension force when the detection roller is in the second target position.

[0010] In another alternative, a drive shaft is also included, which is rotatable to drive the assembly to the adhesive roller.

[0011] In another alternative embodiment, an elastomer and an anti-slip roller are also included, the elastomer being configured to apply a force to the anti-slip roller such that the anti-slip roller can press the bottom film against the drive shaft.

[0012] In another alternative embodiment, an optical fiber sensor is also included. The base film is provided with a through positioning hole. The optical fiber sensor is used to detect the positioning hole, thereby providing feedback on the relative positional relationship between the adhesive and the adhesive roller, so that the adhesive can be aligned with the target component under the drive of the drive shaft.

[0013] In another alternative embodiment, the tape passes around the first guide roller with the overlay located inside the assembly, the assembly passes around the third guide roller with the base film located inside the adhesive body, the third guide roller being located below the first guide roller, and the adhesive roller being located below the third guide roller.

[0014] This application also provides an adhesive device comprising: the aforementioned adhesive application assembly for attaching an adhesive to a first member, which is a target member; and a pressing assembly for pressing the first member, the second member, and the adhesive, such that the first member and the second member are bonded together by the adhesive.

[0015] In an alternative embodiment, the pressing assembly includes a pressure plate and a pressure sensor. The pressure plate is used to apply pressure to the first component, the second component, and the adhesive, and the pressure sensor is connected to the pressure plate to provide feedback on the magnitude of the pressure.

[0016] By adopting the above technical solution and using the above adhesive application components, the separation of adhesive tape, the application of adhesive, and the collection of overlay and base film are all achieved through automated operations, which enables the adhesive to be reliably applied to the target component, thereby saving a lot of manpower and time, and improving the production efficiency and quality of the product.

[0045] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaust all possible methods of this application, nor to limit the scope of this application.

[0046] Figures 3 to 14 An adhesive device 4 according to an embodiment of this application is shown, particularly an adhesive device 4 suitable for an adhesive tape 3 including a cover film 3a, a base film 3b, and an adhesive body 3c. The adhesive body 3c may be a hydrogel, and multiple adhesive bodies 3c may be placed between the cover film 3a and the base film 3b and arranged along the length of the adhesive tape 3. The adhesive device 4 may include a conveying assembly 41, a first feeding assembly 42, an adhesive application assembly 43, an adsorption assembly 44, a clamping assembly 45, a second feeding assembly 46, a pressing assembly 47, a discharging assembly 48, and a control assembly 49.

[0047] Reference Figures 3 to 6 , Figure 9 as well as Figure 10The conveying assembly 41 may include a fixture 41a and an indexing plate 41b. Specifically, the fixture 41a is used to hold the first component 1 (an example of the target component), the second component 2, and the adhesive 3c. Multiple fixtures 41a may be fixed to the indexing plate 41b and evenly arranged in the circumferential direction of the indexing plate 41b. The fixture 41a may be provided with air holes 41c communicating with both sides of its thickness direction (see [link to documentation]). Figure 8 The first component 1, placed on fixture 41a, can block the air hole 41c. The indexing plate 41b can define multiple stations in its circumference, for example, according to the process, it can include a first loading station, an adhesive application station, a second loading station, a pressing station, and an unloading station. The indexing plate 41b can rotate a full circumference under the drive of a motor, so that each fixture 41a can switch between different stations.

[0048] Reference Figure 7 and Figure 8 A first loading assembly 42 can be disposed at a first loading station for placing the first component 1 onto the fixture 41a. Specifically, the first loading assembly 42 may include a feeding tray 42a, a first positioning mechanism 42b, a second positioning mechanism 42c, a robotic arm 42d, a first suction cup 42e, and a second suction cup 42f. The first positioning mechanism 42b is used to perform primary positioning of the first component 1. Primary positioning can have lower positioning accuracy, making it easier for the first component 1 to be placed into the first positioning mechanism 42b. Multiple first positioning mechanisms 42b can be fixed to the feeding tray 42a and evenly arranged in the circumferential direction of the feeding tray 42a. The feeding tray 42a can rotate under the drive of a motor, so that multiple first positioning mechanisms 42b can alternately correspond to the second positioning mechanism 42c. The second positioning mechanism 42c is used to perform secondary positioning of the first component 1. Compared with primary positioning, secondary positioning can have higher positioning accuracy, ensuring that the first component 1 is in the correct position and orientation before being placed into the fixture 41a. The first suction cup 42e and the second suction cup 42f can be fixed to the robotic arm 42d. The robotic arm 42d can move horizontally and vertically under the drive of a cylinder, so that the first suction cup 42e can transfer the first component 1 from the first positioning mechanism 42b to the second positioning mechanism 42c, and the second suction cup 42f can synchronously transfer the first component 1 from the second positioning mechanism 42c to the fixture 41a.

[0049] Reference Figures 9 to 14The adhesive application assembly 43 can be disposed at the adhesive application station for attaching the adhesive 3c to the first component 1. Specifically, the adhesive application assembly 43 may include a substrate 43a, a supply roller 43b, a first receiving shaft 43c, a second receiving shaft 43d, an adhesive application roller 43e, a drive shaft 43f, an elastomer 43g, an anti-slip roller 43h, a first guide roller 43i, a second guide roller 43j, a third guide roller 43k, a fourth guide roller 43l, a fifth guide roller 43m, a fiber optic sensor 43n, a detection roller 43o, a baffle 43p, a guide rail 43q, a slider 43r, a first position sensor 43s, and a second position sensor 43t. The substrate 43a can move horizontally and vertically under the drive of a cylinder or motor. The first receiving shaft 43c, the second receiving shaft 43d, and the drive shaft 43f can be mounted on the base 43a and serve as driving members. The first receiving shaft 43c can rotate relative to the base 43a under the drive of one motor, and the second receiving shaft 43d and the drive shaft 43f can rotate relative to the base 43a under the drive of another motor. The supply roller 43b, the adhesive roller 43e, the anti-slip roller 43h, the guide rollers (first guide roller 43i, second guide roller 43j, third guide roller 43k, fourth guide roller 43l, fifth guide roller 43m), and the detection roller 43o can be mounted on the base 43a and serve as driven members that can rotate freely relative to the base 43a. These shafts and rollers mounted on the base 43a are all arranged parallel to each other.

[0050] The adhesive tape 3 can be wound around the supply roller 43b, which can rotate to release the adhesive tape 3. The coating film 3a can reach the first receiving shaft 43c under the guidance of the first guide roller 43i, the second guide roller 43j, and the detection roller 43o. The first receiving shaft 43c can rotate to drive the coating film 3a to be wound around the first receiving shaft 43c. The base film 3b can reach the second receiving shaft 43d under the guidance of the first guide roller 43i, the third guide roller 43k, the adhesive roller 43e, the fourth guide roller 43l, the fifth guide roller 43m, the drive shaft 43f, and the anti-slip roller 43h. The second receiving shaft 43d can rotate to drive the base film 3b to be wound around the second receiving shaft 43d. The rotation axes of the first guide roller 43i, the second guide roller 43j, and the third guide roller 43k are parallel and offset, thus arranging them in a triangle. The tape 3 passes around the first guide roller 43i, allowing the coating 3a to reach the second guide roller 43j under the guidance of the first guide roller 43i, and the combination of the base film 3b and the adhesive 3c to reach the third guide roller 43k under the guidance of the first guide roller 43i. This allows the coating 3a to separate from the combination of the base film 3b and the adhesive 3c at the first guide roller 43i. In this way, the separation mechanism composed of the first guide roller 43i, the second guide roller 43j, and the third guide roller 43k can smoothly separate the coating 3a and the combination while guiding them, preventing damage or breakage of the tape 3 during separation. The function of the rollers is reused, and the separation mechanism has simple components, a compact structure, and stable operation.

[0051] The tape 3 passes around the first guide roller 43i with the film 3a located inside the assembly, that is, the film 3a is in contact with the first guide roller 43i. The assembly passes around the third guide roller 43k with the bottom film 3b located inside the adhesive body 3c, that is, the bottom film 3b is in contact with the third guide roller 43k, and the adhesive body 3c is exposed when separated.

[0052] The third guide roller 43k is located below the first guide roller 43i, and the adhesive roller 43e is located below the third guide roller 43k. In this way, the exposed adhesive 3c can be immediately bonded to the first component 1 below, which is the target component. The entire device has a compact structure and will not cause contamination or performance degradation of the adhesive 3c due to long-distance operation.

[0053] Reference Figure 12The elastomer 43g can apply a spring force to the anti-slip roller 43h, allowing the anti-slip roller 43h to press the base film 3b against the outer peripheral surface of the drive shaft 43f. For example, the elastomer 43g can be a compression spring. Under the pressure of the anti-slip roller 43h, the base film 3b and the outer peripheral surface of the drive shaft 43f can have a large frictional force, preventing the coating 3a from sliding relative to the outer peripheral surface of the drive shaft 43f.

[0054] Reference Figure 11 and Figure 12 The detection roller 43o and the baffle 43p can be fixed to the slider 43r, which can be mounted on the guide rail 43q. The guide rail 43q can be fixed to the base 43a and extends vertically. The first position sensor 43s and the second position sensor 43t can be fixed to the base 43a and spaced apart along the extension direction of the guide rail 43q. The first position sensor 43s and the second position sensor 43t can be, for example, photoelectric switches. The slider 43r can slide along the guide rail 43q, allowing the baffle 43p to align with either the first position sensor 43s or the second position sensor 43t. When the baffle 43p aligns with the first position sensor 43s, the first position sensor 43s can be triggered by the baffle 43p. At this time, the detection roller 43o can be located at the first target position, and the film 3a can be tensioned by the detection roller 43o and bear the first tension force. When the baffle 43p aligns with the second position sensor 43t, the second position sensor 43t can be triggered by the baffle 43p. At this time, the detection roller 43o can be located at a second target position different from the first target position, and the film 3a can be tensioned by the detection roller 43o and bear a second tension force different from the first tension force.

[0055] Furthermore, compared to the first target position, when the detection roller 43o is located at the second target position, the film 3a around the detection roller 43o can form a smaller angle with the vertical direction, making the second tension less than the first tension. The mounting positions of the first position sensor 43s and the second position sensor 43t can be adjustable, so that the tightness of the film 3a can be limited within a suitable range.

[0056] Reference Figure 13 and Figure 14 In this embodiment, since both the adhesive 3c and the base film 3b are transparent, conventional positioning methods cannot locate the feed position of the tape 3. Therefore, a fiber optic sensor 43n is used in conjunction with positioning holes 3d to locate the feed position of the tape 3. Multiple adhesives 3c and multiple through-holes 3d can be arranged along the length of the tape 3, and one adhesive 3c and two positioning holes 3d can be arranged side-by-side along the width of the tape 3. The light beam emitted from the fiber optic sensor 43n can detect the edge of the positioning hole 3d, enabling the fiber optic sensor 43n to provide feedback on the feed position of the tape 3.

[0057] Before the adhesive 3c is attached to the first component 1, the drive shaft 43f and the second receiving shaft 43d can rotate to drive the base film assembly to the adhesive application roller 43e. With the cooperation of the drive shaft 43f and the fiber optic sensor 43n, the edge of an adhesive 3c can be moved precisely to the lower end of the adhesive application roller 43e, or to the portion of the adhesive application roller 43e closest to the first component 1. The detection roller 43o can be positioned at a first target position, such that the baffle 43p is aligned with the first position sensor 43s.

[0058] After the first component 1 is conveyed to the adhesive application station by the indexing plate 41b, the substrate 43a can move vertically, causing the edge of the adhesive 3c to contact the first component 1. Subsequently, the substrate 43a can move horizontally, for example, from the outside to the inside radially of the indexing plate 41b, causing the adhesive roller 43e to roll the adhesive 3c onto the first component 1. The rolled adhesive 3c separates from the base film 3b and adheres to the first component 1. At the same time, redundant film 3a is generated at the first guide roller 43i, causing the film 3a around the detection roller 43o to become loose. Under the action of gravity, the detection roller 43o will move downward to ensure that the film 3a remains taut. Once the detection roller 43o reaches the second target position, the baffle 43p will trigger the second position sensor 43t. The first receiving shaft 43c can start rotating upon feedback from the second position sensor 43t, allowing the redundant portion of the coating 3a to be received within the first receiving shaft 43c, while the baffle 43p moves upward. Once the detection roller 43o returns to the first target position, the first receiving shaft 43c will stop rotating. Thus, with the cooperation of the first receiving shaft 43c, the first position sensor 43s, and the second position sensor 43t, the coating 3a can always be kept in a taut state with a suitable degree of tension.

[0059] Reference Figure 9 and Figure 10The adsorption assembly 44 and the clamping assembly 45 can be disposed at the adhesive application station to prevent the first component 1 from shifting during the rolling process. Specifically, the adsorption assembly 44 may include a third suction cup 44a, which can move vertically under the drive of a cylinder. When the first component 1 is conveyed to the adhesive application station by the indexing plate 41b, the third suction cup 44a can abut against the fixture 41a. At this time, the edge of the third suction cup 44a can fit tightly against the fixture 41a, and the air hole 41c on the fixture 41a can be connected to the air passage of the third suction cup 44a. The third suction cup 44a can draw gas from the air hole 41c, so that the air hole 41c is in a negative pressure state, and the first component 1 can be tightly attached to the fixture 41a under atmospheric pressure. The clamping assembly 45 may include a pressure block 45a, which can move vertically under the drive of a cylinder. After the first component 1 is conveyed to the adhesive application station by the indexing plate 41b, the pressure block 45a can abut against the first component 1. The first component 1, being abutted against, can be tightly attached to the fixture 41a, thereby further preventing the first component 1 from shifting.

[0060] Reference Figures 3 to 6 The second loading assembly 46 is disposed at the second loading station and is used to transport the second component 2 to the fixture 41a. The second loading assembly can have a similar configuration to the first loading assembly 42. Compared with the first loading assembly 42, the difference of the second loading assembly 46 lies in the shape of the positioning mechanism and the arrangement of the suction cups, that is, the shape of the positioning mechanism and the arrangement of the suction cups need to be adapted to the shape of the second component 2.

[0061] A pressing assembly 47 is disposed at the pressing station for pressing the first component 1, the second component 2, and the adhesive 3c. Specifically, the pressing assembly 47 may include a pressure plate and a pressure sensor. The pressure plate can move vertically under the drive of a cylinder. After the first component 1, the second component 2, and the adhesive 3c are conveyed to the pressing station by the indexing plate 41b, the pressure plate can press the first component 1, the second component 2, and the adhesive 3c together, so that the first component 1 and the second component 2 can be bonded to each other through the adhesive 3c. The pressure sensor can be connected to the pressure plate to provide feedback on the pressure applied by the pressure plate to the first component 1, the second component 2, and the adhesive 3c.

[0062] The unloading assembly 48 can be disposed at the unloading station for removing the bonded parts (the first component 1, the second component 2, and the bonded body 3c after pressing) from the fixture 41a. Specifically, the unloading assembly 48 may include a fourth suction cup and a dropping plate 48a. The fourth suction cup can move horizontally and vertically under the drive of a cylinder. The dropping plate 48a can be disposed radially outside the indexing plate and extend radially in the indexing disk 41b. The dropping plate 48a can be arranged at an angle, such that the end of the dropping plate 48a near the indexing disk 41b is higher than the end of the dropping plate 48a away from the indexing disk 41b. After the bonded parts are conveyed to the unloading station by the indexing disk 41b, the fourth suction cup can transfer the bonded parts from the fixture 41a to the dropping plate 48a, and the bonded parts falling into the dropping plate 48a can leave the bonding device 4 under the guidance of the dropping plate 48a.

[0063] The control component 49 may include a touch screen 49a, a controller, and a driver. Specifically, the controller may be electrically connected to the touch screen 49a and the driver; for example, the controller may be a programmable logic controller (PLC). The touch screen 49a is used for initial debugging of the bonding device 4 and for later editing of the processing program. The driver is used to drive the motor and cylinder under the control of the controller.

[0064] Thus, by using the aforementioned adhesive application assembly 43, the separation of the adhesive tape 3, the application of the adhesive body 3c, and the collection of the overlay film 3a and the base film 3b are all achieved through automated operations. This allows the adhesive body 3c to be reliably applied to the first component 1, thereby saving a significant amount of manpower and time, and improving product production efficiency and quality. Furthermore, by providing the pressing assembly 47, the pressing force can be kept consistent, and the pressing force can be evenly applied to the first component 1, the second component 2, and the adhesive body 3c, enabling the first component 1 and the second component 2 to be reliably bonded together.

[0065] It should be understood that the above embodiments are merely exemplary and are not intended to limit this application. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this application without departing from the scope of this application.

[0066] It should be understood that the adhesive 3c is not limited to hydrogels, and can be any possible material known to those skilled in the art.

[0067] It should be understood that the elastomer 43g is not limited to compression springs; for example, it can be a torsion spring.

[0068] It should be understood that the position sensor is not limited to a photoelectric switch, but can be, for example, a limit switch. The number of position sensors is not limited to two. For example, the number of position sensors can be one, and the first receiving shaft 43c can be configured to rotate when the baffle 43p is misaligned with the position sensor. The detection roller 43o is not limited to tensioning the film 3a by gravity; for example, an elastic force can be applied to the detection roller 43o to tension the film 3a. The magnitude of the first tension force is not limited to being different from the second tension force. For example, in possible embodiments, the first tension force can be the same as the second tension force.

[0069] It should be understood that the bonding device 4 is not limited to the above-mentioned workstations. For example, a detection workstation may also be provided for detecting whether the first component 1 and the second component 2 are placed on the fixture 41a.
