Technical Field
[0001] This invention belongs to the field of product processing technology, and specifically relates to an attachment mechanism and attachment method. Background Technology
[0002] In the automation industry, auxiliary materials (such as FPCs) can be easily picked up and attached. This is achieved by using a material peeler to peel off the auxiliary material, then using a suction nozzle to pick up the material, and using vision guidance to attach the material to the designated position. However, some FPC products in consumer electronics require pre-bending, and after bending, high-precision attachment and assembly are still required. Currently, it is not possible to automate the bending and attachment operations, which reduces work efficiency. Summary of the Invention

[0020] In the automation industry, auxiliary materials (such as FPCs) can be easily picked up and attached. This is achieved by using a material peeler to peel off the auxiliary material, then using a suction nozzle to pick up the material, and using vision guidance to attach the material to the designated position. However, some FPC products in consumer electronics require pre-bending, and after bending, high-precision attachment and assembly are still required. Currently, it is not possible to automate the bending and attachment operations, which reduces work efficiency.
[0021] Figure 1 A schematic diagram of the attachment mechanism for FPC40 according to an embodiment of the present invention is shown. Figure 1 As shown, this invention proposes an attachment mechanism and method for FPC40. The attachment mechanism for FPC40 includes a base, a movable member 10, a first bending member 20, and a second bending member 30. The base has a working station for placing the attachment to be attached. The attachment has a through hole. The movable member 10 is located on the base and configured to pick up the FPC40 and attach the main body 41 to the top of the attachment (i.e., the side of the attachment facing the movable member 10, which is also the upper end of the attachment). The first bending member 20 is located on the base and is capable of... Moving along the first direction X, the first bending member 20 is configured to squeeze and bend the bendable portion 42 so that the bent bendable portion 42 can pass through the through hole. The second bending member 30 is provided on the base and can move along the first direction X and the second direction Y respectively. The second bending member 30 is configured to attach the bendable portion 42 passing through the through hole to the bottom end of the attachment to be attached (i.e., the side of the attachment to be attached away from the moving member 10, which is also the lower end of the attachment to be attached). The first direction X and the second direction Y are intersecting.
[0022] By using the attachment mechanism for FPC40 in this technical solution, the moving member 10 can pick up the FPC40 and move it above the attachment to be attached. Then, the first bending member 20 can squeeze and bend the bendable portion 42. Then, the moving member 10 moves the FPC40 toward the attachment to be attached, so that the main body 41 is attached to the top of the attachment to be attached, and the bendable portion 42 passes through the through hole. Then, the second bending member 30 squeezes the bendable portion after it passes through the through hole and attaches it to the bottom of the attachment to be attached. The attachment mechanism of this invention can not only realize the bending operation of the bendable portion 42 of the FPC40, but also realize the two-fold attachment operation of the FPC40 at the top and bottom of the attachment to be attached, thus improving the degree of automation and work efficiency.
[0023] Specifically, in this embodiment, FPC40 is a flexible printed circuit board (FPC40 for short), which is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as a substrate.
[0024] Specifically, in this embodiment, the attachment to be attached is a plate-shaped structure with through holes. The top end of the plate-shaped structure is used to attach and bond to the main body 41 of the FPC40, and the bottom end of the plate-shaped structure is used to attach and bond to the bendable part 42 passing through the through holes, thereby bending the FPC40 to attach and bond to both sides of the plate-shaped structure.
[0025] Specifically, in this embodiment, at least one of the top end and the main body 41 of the attachment to be applied is provided with adhesive, thereby facilitating the bonding of the attachment to be applied and the main body 41. At least one of the bottom end and the bendable part 42 of the attachment to be applied is provided with adhesive, thereby facilitating the bonding between the attachment to be applied and the bendable part 42. The bonding operation is completed when the top end and the main body 41 of the attachment to be applied are attached, and when the bottom end of the attachment to be applied is attached to the bendable part 42.
[0026] In some embodiments of the present invention, such as Figure 2 As shown, the moving component 10 includes a picking component 11 and a driving component. The driving component is connected to the picking component 11. The picking component 11 is used to pick up the main body 41, and the driving component is used to move the picking component 11 after picking up the main body 41 and attach the main body 41 to the top of the attachment to be attached. In this embodiment, the driving component can be a cylinder, a motor, a robotic arm, or other driving components, used to drive the picking component 11 to pick up the FPC 40 from the material buffer position, and then move the picking component 11 to the top of the attachment to be attached by moving along the first direction X, the second direction Y, and the third direction Z. In this embodiment, the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other.
[0027] Specifically, in this embodiment, the picking component 11 can be a suction nozzle. The suction nozzle uses a negative pressure principle (such as a vacuum pump) to quickly adsorb the FPC40, completing the tasks of grasping, handling, or fixing without direct contact. In this embodiment, it can pick up the main body 41 of the FPC40, thereby moving the entire FPC40. The suction nozzle can pick up precisely, avoiding contamination or damage caused by manual operation. In addition, when the suction nozzle is used in conjunction with a robotic arm or automated equipment, it can achieve precise positioning, making it suitable for high-precision scenarios and significantly improving production efficiency and product qualification rate. Alternatively, the picking component 11 can also be a robotic arm or an automated fixture, both of which can pick up and move the FPC40.
[0028] In some embodiments of the present invention, such as Figure 2 As shown, the movable component 10 also includes a sliding sleeve 12, which is sleeved on the outside of the picking component 11 and connected to the driving component. The driving component can drive the picking component 11 to move through the sliding sleeve 12. When the picking component 11 comes into contact with the attachment to be applied, the sliding sleeve 12 and the picking component 11 can slide relative to each other along the axial direction of the sliding sleeve 12. In this embodiment, when the driving component drives the FPC 40 on the picking component 11 to move onto the attachment to be applied through the sliding sleeve 12, it will compress the attachment to be applied and the main body 41 of the FPC 40, thereby causing the main body 41 and the attachment to be applied to complete the bonding. When the picking component 11 comes into contact with the attachment to be applied, the sliding sleeve 12 is configured to slide relative to the picking component 11 along the axial direction of the sliding sleeve 12, which can perform a pressure-holding operation between the attachment to be applied and the FPC 40, preventing excessive pressure from damaging the main body 41 and the attachment to be applied, and improving reliability.
[0029] In some embodiments of the present invention, such as Figure 2 As shown, the outer periphery of the take-up member 11 is provided with a first limiting part 111 and a second limiting part 112. The first limiting part 111 and the second limiting part 112 are spaced apart along the axial direction of the sliding sleeve 12. The first limiting part 111 is located on the side of the second limiting part 112 away from the working position. The sliding sleeve 12 is located between the first limiting part 111 and the second limiting part 112. The end of the sliding sleeve 12 near the working position is connected to the second limiting part 112 through a first elastic member 13, and the end of the sliding sleeve 12 away from the working position abuts against the first limiting part 111. In this embodiment, the sliding sleeve 12 is movably sleeved on the take-up member 11 along its own axial direction and is connected to the second limiting part 112 through the first elastic member 13. In this embodiment, the first elastic member 13 is initially in a compressed state, that is, it always provides a squeezing force to the sliding sleeve 12, causing the sliding sleeve 12 to abut against the first limiting part 111.
[0030] When the driving component moves the sliding sleeve 12, the squeezing force of the first elastic element 13 causes the picking component 11, the first elastic element 13, and the sliding sleeve 12 to move as a whole, thereby causing the driving component to move the picking component 11, the first elastic element 13, and the sliding sleeve 12 simultaneously. When the main body 41 picked up by the picking component 11 comes into contact with the accessory to be attached, if the squeezing force of the driving component is too large, the first elastic element 13 will be compressed again, causing relative sliding between the sliding sleeve 12 and the picking component 11, thus avoiding damage to the main body 41 and the accessory to be attached due to excessive squeezing force.
[0031] Furthermore, in an embodiment of the present invention, the first elastic element 13 can be a spring. In other embodiments of the present invention, the first elastic element 13 can also be a rubber element or other elastic component, which can also achieve self-compression and ultimately achieve relative sliding between the sliding sleeve 12 and the taking-up element 11 to achieve pressure holding effect.
[0032] Furthermore, in this embodiment, the end of the take-up component 11 facing the work station has a suction nozzle and a pressure sensor. The pressure sensor and the suction nozzle are misaligned, which allows the pressure value between the take-up component 11 and the attachment to be applied to be measured without hindering the suction nozzle from picking up the main body 41. This enables the driving force of the drive component to be adjusted in real time according to the pressure value, further avoiding damage between the main body 41 and the attachment to be applied due to excessive squeezing pressure.
[0033] Specifically, in this embodiment, the first limiting part 111 and the second limiting part 112 can be protrusions. Since the sliding sleeve 12 is a ring structure, the first limiting part 111 can limit the side of the take-up piece 11 away from the work station. Similarly, the second limiting part 112 can also limit the side of the first elastic member 13 facing the work station.
[0034] In addition, the first limiting part 111 and the second limiting part 112 in this embodiment can also be annular, which can also limit the side of the take-up piece 11 away from the work station by the first limiting part 111, and limit the side of the first elastic member 13 facing the work station by the second limiting part 112.
[0035] In some embodiments of the present invention, such as Figure 3As shown, the first bending member 20 includes a first bending portion and a first driving portion 21. The first driving portion 21 is connected to the first bending portion and can drive the first bending portion to move along the first direction X. The first bending portion is located at the top of the bendable portion 42 (i.e., the side of the bendable portion 42 facing the first bending member 20, which is also the upper end of the bendable portion 42). In this embodiment, the first driving portion 21 can be a cylinder, a motor, a robotic arm, or other driving components, used to drive the first bending portion to move toward the bendable portion 42. In this embodiment, the first bending portion includes a first plate 221 and a second plate 222. The first plate 221 is located at the bottom end of the first driving portion 21, and the second plate 222 is located at the bottom end of the first plate 221 and is disposed close to the picking member 11. The first plate 221 and the picking member 11 are spaced apart, so as not to affect the movement of the picking member 11 and the first bending portion, thus improving reliability.
[0036] In some embodiments of the present invention, such as Figure 2 and 3 As shown, the second bending member 30 includes a second bending portion 31 and a second driving portion. The second driving portion is connected to the second bending portion 31 and can drive the second bending portion 31 to move along the first direction X and the second direction Y, respectively. The second bending portion 31 is located on the side of the bendable portion 42 away from the main body portion 41. In this embodiment, the second driving portion can be a cylinder, a motor, a robotic arm, or other driving components, used to drive the second bending portion 31 to move toward the bendable portion 42. The second driving portion drives the second bending portion 31 to first move along the second direction Y to abut against the bendable portion, then drives the bendable portion to bend, and then the second bending portion 31 moves along the first direction X, that is, the bent bendable portion abuts against the bottom end of the attachment to be attached, so as to achieve the attachment and bonding between the bendable portion and the attachment to be attached.
[0037] In some embodiments of the present invention, such as Figure 2 and 3 As shown, the second bending member 30 also includes a sleeve portion 32, which is sleeved outside the second bending portion 31 and connected to the second driving portion. The second driving portion can drive the second bending portion 31 to move through the sleeve portion 32. When the second bending portion 31 abuts against the attachment to be applied, the sleeve portion 32 and the second bending portion 31 can slide relative to each other along the axial direction of the sleeve portion 32. In this embodiment, when the second driving portion drives the second bending portion 31 to move through the sleeve 32, it will compress the attachment to be applied and the main body 41 of the FPC 40, thereby promoting the adhesion between the main body 41 and the attachment to be applied. When the second bending portion 31 abuts against the attachment to be applied, the sleeve portion 32 and the second bending portion 31 can slide relative to each other along the axial direction of the sleeve portion 32, which can perform a pressure-holding operation on the adhesion between the attachment to be applied and the FPC 40, preventing excessive pressure from damaging the main body 41 and the attachment to be applied, and improving reliability.
[0038] In some embodiments of the present invention, such as Figure 2 and 3 As shown, the outer periphery of the second bending portion 31 is provided with a first stop portion 311 and a second stop portion 312. The first stop portion 311 and the second stop portion 312 are spaced apart along the axial direction of the sleeve portion 32. The first stop portion 311 is located on the side of the second stop portion 312 closer to the working position. The sleeve portion 32 is located between the first stop portion 311 and the second stop portion 312. The end of the sleeve portion 32 closer to the working position is connected to the first stop portion 311 through a second elastic member 33, and the end of the sleeve portion 32 away from the working position abuts against the second stop portion 312. In this embodiment, the sleeve 32 is movably sleeved on the outside of the second bending portion 31 along its own axial direction and is connected to the first stop portion 311 through the second elastic member 33. In this embodiment, the initial state of the second elastic member 33 is a compressed state, that is, it always provides a compressive force to the sleeve 32, causing the sleeve 32 to abut against the first stop portion 311.
[0039] When the second drive unit moves the sleeve 32, the pressure of the second elastic element 33 causes the second bending part 31, the second elastic element 33, and the sleeve 32 to move as a whole. This causes the second drive unit to simultaneously move the second bending part 31, the second elastic element 33, and the sleeve 32. When the second bending part 31 comes into contact with the accessory to be applied, if the pressure of the second drive unit is too great, the second elastic element 33 will be compressed again, causing relative sliding between the sleeve 32 and the second bending part 31. This prevents damage to the main body 41 and the accessory to be applied due to excessive pressure.
[0040] Furthermore, in an embodiment of the present invention, the second elastic element 33 can be a spring. In other embodiments of the present invention, the second elastic element 33 can also be a rubber part or other elastic component, which can also achieve self-compression and ultimately achieve relative sliding between the sleeve 32 and the second bent part 31 to achieve pressure holding effect.
[0041] Furthermore, in this embodiment, the end of the second bending part 31 facing the work station has a pressure sensor, which can measure the pressure value between the bending part and the attachment to be applied, and then adjust the driving force of the second drive part in real time according to the pressure value, so as to further avoid damage between the main body part 41 and the attachment to be applied due to excessive extrusion pressure.
[0042] Specifically, in this embodiment, the first stop 311 and the second stop 312 can be protrusions. Since the sleeve 32 has an annular structure, the first stop 311 can limit the second elastic member 33. Similarly, the second limiting part 112 can also limit the side of the sleeve 32 away from the working position.
[0043] Alternatively, the first limiting part 111 and the second limiting part 112 in this embodiment can also be annular, which can also enable the first stop part 311 to limit the second elastic member 33 and the second stop part 312 to limit the side of the sleeve 32 away from the working position.
[0044] In some embodiments of the present invention, such as Figure 3 As shown, the second bending portion 31 has a pressing end 313 at one end facing the first bending member 20, and the pressing end 313 has an inclined surface 3131 on the side facing the bendable portion 42. The inclined surface 3131 is biased towards the bendable portion 42 at one end away from the first bending member 20. In this embodiment, the inclined surface 3131 is inclined to facilitate maintaining contact with the bendable portion 42 when the pressing end 313 moves towards the bendable portion 42, thereby preventing the tip of the pressing end 313 from scratching the bendable portion 42. In addition, the inclined surface 3131 also facilitates the guidance of the bendable portion 42, improving the protection and guidance of the bendable portion 42.
[0045] Furthermore, in this embodiment, the FPC40 attachment mechanism also includes a vision inspection component, which is disposed on the base. In this embodiment, the vision inspection component can be an industrial camera, which is set towards the work station and is used to detect the attachment status of the FPC40 and the attachment to be attached.
[0046] Furthermore, the operation flow of the attachment mechanism of the present invention is as follows: the suction nozzle completes the suction of the FPC40, and then, after the suction nozzle completes the material picking up of the FPC40, the first bending member 20 completes the bending of the FPC40 to prepare for the through hole and attachment. Before completing the through hole, the second bending member 30 is in the waiting position (that is, the second bending part 31 of the second bending member 30 is located on the side of the bendable part 42 away from the main body part 41 and located at the bottom end of the main body part 41). After the bendable part 42 of the bent FPC40 passes through the through hole, the second bending member 30 moves to complete the attachment work of the bendable part 42 and the back of the attachment to be attached. The movement direction of the second bending member 30 includes two degrees of freedom: the first direction X and the second direction Y. While moving towards the second direction Y, it moves upward along the first direction X (in this embodiment, the first direction X is the vertical direction and the second direction Y is the horizontal direction) to ensure the reliability of the adhesion. Finally, the through holes of the FPC40 and the accessories to be attached were completed and the attachment was applied. In order to ensure that the attachment accuracy reaches 0.05mm, the viewing angle of the part was checked and photographed after the attachment was completed to determine whether the attachment effect was qualified.
[0047] This invention also proposes an attachment method for FPC40, such as... Figure 4 As shown, the attachment method used in the above-mentioned attachment mechanism includes: S10: Drive the moving part 10 to pick up the entire FPC40 and place it above the part to be adsorbed; S20: Drive the first bending member 20 to move toward the bendable portion 42 of the FPC40 located above the attachment to be attached and bend the bendable portion 42. S30: Drive the moving part 10 to move the bent integral FPC 40 toward the part to be adsorbed until the bendable part 42 passes through the through hole of the part to be adsorbed and attaches the main body part 41 to the top of the part to be adsorbed. S40: Drive the second bending member 30 towards the bendable portion 42 after passing through the through hole and press it until the bendable portion 42 is attached to the bottom end of the attachment to be attached. Specifically, in this embodiment, the take-up member 11 is used to pick up and move the FPC40 as a whole, the first bending member 20 is used to pre-bend the bendable portion 42, and then the take-up member 11 moves towards the work station to make the main body 41 adhere to the attachment to be attached, while allowing the bendable portion 42 to pass through the through hole. Finally, the second bending member 30 moves towards the bendable portion 42 and attaches the bendable portion 42 to the bottom end of the attachment to be attached, thus realizing the bending of the FPC40 and the double-sided attachment to the attachment to be attached. It can realize the bending operation of the bendable portion 42 of the FPC40, and also realize the double-sided attachment operation of the FPC40 to the top and bottom of the attachment to be attached, improving the degree of automation and work efficiency.
[0048] In some embodiments of the present invention, driving the second bending member 30 toward the bendable portion 42 after passing through the through hole and pressing it includes: S41: Drive the second bending member 30 to move along the second direction Y and press the bendable part 42 until the bendable part 42 rotates around the connection position between the bendable part 42 and the main body part 41 by a preset angle. S42: Drive the second bending member 30 to move along the first direction X until the bendable part 42 is attached to the bottom end of the attachment to be attached.
[0049] Specifically, in this embodiment, the movement direction of the second bending member 30 includes two degrees of freedom: a first direction X and a second direction Y. It moves laterally in the second direction Y while simultaneously moving upwards along the first direction X (in this embodiment, the first direction X is vertical, and the second direction Y is horizontal), ensuring reliable adhesion. The preset angle in this embodiment is the angle between the main body 41 and the bendable part 42, and it is an acute angle. This angle needs to be designed according to specific circumstances and can be obtained using a visual inspection device.
[0050] In some embodiments of the present invention, the second bending member 30 moves toward and is pressed toward the bendable portion 42 after passing through the through hole, until the bendable portion 42 is attached and bonded to the bottom end of the member to be adsorbed, and then the following steps are taken: S50: Drives the vision inspection unit to take pictures of the workstation; Determine whether the affixing is acceptable based on the content of the photograph.
[0051] Furthermore, the attachment method in this invention can handle complex FPC40 attachment tasks under special circumstances, replacing the complex manual operations and improving automation and work efficiency. Visual guidance also significantly improves attachment accuracy, achieving an error of less than 0.05mm. The FPC40 attachment mechanism can be extended to similar situations, enabling the attachment of auxiliary materials for different products through quick-change of related parts. This represents a technological breakthrough in automation design solutions and is an excellent choice for automation-compatible mechanisms, improving the versatility, reusability, and high precision of auxiliary material attachment in equipment.
