Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of application devices, and more specifically, relates to an application mechanism. Background Technology
[0002] In modern society, automobiles have become ubiquitous as an important means of transportation, and their various functional configurations are increasingly diverse. For example, many car sunroofs typically require the use of hook-and-loop fasteners or Velcro to accommodate sunshades or decorative elements. Hook-and-loop fasteners are self-adhesive, flexible connectors commonly used for removable fastening. In practice, users typically attach the hook-and-loop fasteners to the designated positions on the sunroof component, then use a large pressing component to firmly secure them to the surface.
[0003] However, hook and loop fasteners are mostly made of flexible materials, with a certain degree of elasticity and slight structural undulations on their surface. When using traditional rigid clamping components for direct overall compression, localized stress concentration often occurs: that is, although the clamping component is in general contact with the hook and loop surface, due to flatness errors in the workpiece or the fastener itself, some areas will be compressed first, while other areas may not be fully compressed due to slight height differences or the fastener's elasticity not being fully engaged. This uneven compression can easily affect the compression effect of other parts of the clamping component. This uneven compression can lead to some hook and loop fasteners not being fully compressed, thus affecting their actual bonding strength and subsequent reliability.

[0047] It should be noted that the term "multiple" means two or more, unless otherwise explicitly specified.
[0048] Please refer to the following: Figures 1 to 5 The application mechanism provided by this utility model will now be described. The application mechanism includes: a frame 1, a first workstation 11, a first lifting seat 21, a lifting drive mechanism, a lowering seat 22, and a first buffer mechanism; the first workstation 11 is used to place the workpiece 6; the first workstation 11 is set on the frame 1; the lifting drive mechanism is used to drive the first lifting seat 21 to move up and down; the lowering seat 22 is used to press down on the workpiece 6 at the first workstation 11; the lowering seat 22 is located below the first lifting seat 21; there are multiple lowering seats 22 and multiple first buffer mechanisms, and the multiple lowering seats 22 and multiple first buffer mechanisms correspond one-to-one; A buffer mechanism includes: a first mounting hole, a first slide rod 31, a first elastic element 32, and a first limiting element 33; the first mounting hole is formed on a first lifting seat 21 and extends vertically; the first slide rod 31 is inserted into the first mounting hole; the first limiting element 33 is disposed at the upper end of the first slide rod 31; a lower pressure seat 22 is connected to the lower end of the first slide rod 31; the first lifting seat 21 is located between the first limiting element 33 and the lower pressure seat 22; the first lifting seat 21 and the lower pressure seat 22 are spaced apart, and the first elastic element 32 is disposed between the first lifting seat 21 and the lower pressure seat 22.
[0049] Thus, the frame 1 is provided with a first workstation 11, on which the workpiece 6 can be placed; the lifting drive mechanism can drive the first lifting seat 21 to move up and down; the first lifting seat 21 is provided with a first mounting hole; a first sliding rod 31 is inserted into the first mounting hole, and the lower end of the first sliding rod 31 is connected to a lower pressure seat 22, which can slide up and down in the vertical direction with the first sliding rod 31; the first lifting seat 21 is located between the lower pressure seat 22 and the first limiting member 33, and the lower pressure seat 22 and the first lifting seat 21 are spaced apart, and a first elastic member 32 is provided between the lower pressure seat 22 and the first lifting seat 21; the lower pressure seat 22 and the workpiece 6 are connected by a first elastic member 32. When the workpiece 52 to be pasted comes into contact, the first elastic element 32 can provide a buffer to avoid rigid collision between the pressure seat 22 and the workpiece 6; the distance between the pressure seat 22 and the first lifting seat 21 can change under the action of external force; there are multiple pressure seats 22 and multiple first buffer mechanisms, with each pressure seat 22 corresponding to one first buffer mechanism; when multiple pressure seats 22 press the workpiece 52 to be pasted on the workpiece 6, since each pressure seat 22 can press on the workpiece 52 to be pasted independently, the pressing state between different pressure seats 22 will not affect each other, thus avoiding the pressing state of other pressure seats 22 after one pressure seat 22 is pressed.
[0050] In one embodiment, the first station 11 may be a space, cavity, or surface area on the frame 1 where the workpiece 6 is placed.
[0051] In one embodiment, the second station 12 may be a space, cavity, or surface area on the frame 1 where the workpiece 6 is placed.
[0052] In one embodiment, the vertical direction is perpendicular to the horizontal plane.
[0053] In one embodiment, the first elastic element 32 is a helical spring sleeved on the first slide bar 31.
[0054] In one embodiment, any two adjacent first slide rods 31 are spaced apart. In another embodiment, any two adjacent lower pressure seats 22 are spaced apart.
[0055] In one embodiment, the part to be attached 52 is a mushroom-shaped hook and loop fastener or Velcro.
[0056] In one embodiment, the first elastic element 32 is clamped between the first lifting seat 21 and the lowering seat 22.
[0057] In one embodiment, the first slide rods 31 are respectively arranged vertically.
[0058] In one embodiment, the lifting drive mechanism is mounted on the frame 1.
[0059] Further, please refer to Figures 1 to 5As a specific embodiment of the bonding mechanism provided by this utility model, when the external force is removed from the lower pressure seat 22, the bottom surface of each lower pressure seat 22 is located on the same horizontal plane. In this way, each lower pressure seat 22 can be pressed more evenly onto the part to be bonded 52.
[0060] Furthermore, when the lifting drive mechanism stops applying pressure and returns to its initial position, each first elastic element 32 pushes the corresponding first slide bar 31 upwards using its own elastic restoring force until the first limiting element 33 makes top contact with the first lifting seat 21, thereby ensuring that all lower pressing seats 22 are synchronously pulled back to the standard reference height. Since the first limiting element 33 is limited on the same platform of the first lifting seat 21, the bottom surface of each lower pressing seat 22 is naturally uniformly positioned on the same horizontal plane. This design can significantly improve the repeatability of the bonding mechanism: at the beginning of each bonding cycle, each lower pressing seat 22 descends simultaneously from the same height, avoiding the initial position difference caused by residual displacement from the previous bonding. In addition, the coplanar bottom surfaces of multiple lower pressing seats 22 mean that during the bonding process, the initial contact timing between each point and the surface of the workpiece 6 is almost the same, thus keeping the pressure stroke of the first elastic element 32 synchronous, and finally obtaining a uniform and synchronous pressing force distribution on the surface of the workpiece 6, eliminating bonding defects caused by local overpressure or underpressure. In addition, if the user needs to restore different pressure seats 22 to their initial positions, the operator does not need to perform independent height leveling on each pressure seat 22, which greatly reduces the tooling debugging time and also reduces the probability of poor clamping caused by human error.
[0061] Further, please refer to Figures 1 to 5As a specific embodiment of the attaching mechanism provided by this utility model, the lifting drive mechanism includes: a second lifting seat 23, a lifter for driving the second lifting seat 23 to move up and down, and a second buffer mechanism; the second buffer mechanism includes: a second mounting hole, a second slide rod 34, a second elastic element 35, and a second limiting element 36; the second mounting hole is opened on the second lifting seat 23 and extends in the vertical direction, the second slide rod 34 is inserted into the second mounting hole, and the second limiting element 36 is disposed at the upper end of the second slide rod 34; the first lifting seat 21 is connected to the lower end of the second slide rod 34; the second lifting seat 23 is located between the second limiting element 36 and the first lifting seat 21; the second lifting seat 23 and the first lifting seat 21 are spaced apart, and the second elastic element 35 is disposed between the second lifting seat 23 and the first lifting seat 21. Thus, a second mounting hole is provided on the second lifting seat 23; a second sliding rod 34 is inserted into the second mounting hole, and the lower end of the second sliding rod 34 is connected to the first lifting seat 21. The first lifting seat 21 can slide up and down in the vertical direction with the second sliding rod 34; the first lifting seat 21 is located between the second lifting seat 23 and the second limiting member 36, and the second lifting seat 23 and the first lifting seat 21 are spaced apart. A second elastic member 35 is provided between the second lifting seat 23 and the first lifting seat 21, and the second elastic member 35 can provide buffering between the first lifting seat 21 and the second lifting seat 23; a two-stage buffering effect can be achieved with the cooperation of the first elastic member 32 and the second elastic member 35.
[0062] In addition, the first elastic element 32 and the second elastic element 35 of the two-stage buffer can gradually attenuate the vibration energy during rebound, protecting the first station 11 from reverse impact.
[0063] In one embodiment, the lifting device includes: a first Z-slide rail 251 mounted on a frame 1, a first Z-slide table 252 slidably mounted on the first Z-slide rail 251, and a first Z-drive unit for driving the first Z-slide table 252 to move; a second lifting seat 23 is mounted on the first Z-slide table 252. Thus, the first Z-slide table 252 can drive the second lifting seat 23 to move up and down, and during the movement of the second lifting seat 23, it can drive the first lifting seat 21 and the lower pressure seat 22 to move up and down.
[0064] In one embodiment, the first Z-drive unit is a motor or a telescopic cylinder.
[0065] In one embodiment, the second elastic element 35 is clamped between the second lifting seat 23 and the first lifting seat 21.
[0066] In one embodiment, the lift is mounted on the frame 1.
[0067] Further, please refer to Figures 1 to 5In one specific embodiment of the application mechanism provided by this utility model, the first slide bar 31 and the second slide bar 34 are arranged in parallel. Thus, the sliding directions of the lower pressure seat 22 and the first lifting seat 21 can remain consistent.
[0068] Further, please refer to Figures 1 to 5 As a specific embodiment of the bonding mechanism provided by this utility model, each pressing seat 22 is provided with a buffer 24 at its bottom. In this way, when the pressing seat 22 presses down on the part to be bonded 52, the impact force can be buffered by the buffer 24.
[0069] Furthermore, the buffer 24 is located directly on the contact interface between the lower pressure seat 22 and the workpiece 6. It undergoes a slight deformation before the first elastic element 32 at the moment of contact, absorbing some of the impact kinetic energy in a very short time. Additionally, the buffer 24 has an adaptive covering capability to the microscopic morphology of the workpiece 6 surface: when the workpiece 6 has local unevenness or height differences, the buffer 24 can deform accordingly in the pressure area, keeping the force on the bottom surface of the lower pressure seat 22 balanced. Furthermore, the buffer 24 is located at the foremost point, directly shielding the workpiece 6's fragile surface from the hard edges of the lower pressure seat 22. Moreover, the buffer 24 can be used as a replaceable wear part. When its performance deteriorates due to long-term operation, the operator only needs to replace the buffer 24 to restore the original clamping characteristics of the application mechanism without disassembling the first lifting seat 21 or the first sliding rod 31, significantly reducing maintenance complexity.
[0070] In one embodiment, the buffer 24 is a one-piece piece made of polyurethane.
[0071] Further, please refer to Figures 1 to 5 As a specific embodiment of the bonding mechanism provided by this utility model, when the external force is removed from the pressing seat 22, the bottom surfaces of each buffer member 24 are located on the same horizontal plane. In this way, each buffer member 24 can be pressed more evenly onto the part 52 to be bonded.
[0072] Furthermore, the initial contact time between each buffer component 24 and the workpiece 6 in the next work cycle is synchronized, preventing a buffer component 24 from prematurely contacting the workpiece 6 due to residual compression, thus avoiding localized overpressure. Additionally, when the bonding mechanism needs to switch between different batches of workpieces 6, coplanar zeroing greatly simplifies process preparation: operators do not need to measure the extension of each buffer component 24 individually; they only need to confirm that the first lifting seat 21 has returned to its original position to begin a new round of bonding, significantly shortening the production cycle. Moreover, under long-term operating conditions, coplanar zeroing ensures that the cumulative compressive fatigue of all buffer components 24 remains consistent, preventing premature failure of individual buffer components 24; combined with a visual horizontal reference, maintenance personnel can easily identify abnormally dented buffer components 24, enabling proactive preventative maintenance.
[0073] Further, please refer to Figures 1 to 5As a specific embodiment of the bonding mechanism provided by this utility model, the buffer 24 is a polyurethane block. Thus, the polyurethane block has comprehensive mechanical properties of high resilience, high wear resistance, and high tear resistance. During the bonding process, it can quickly return to its original shape after multiple cycles of compression, assisting the lower pressure seat 22 in maintaining a stable clamping force output.
[0074] In addition, polyurethane blocks naturally possess excellent resistance to oil, water, and chemicals. Even if the application mechanism is exposed to lubricating oil mist or cleaning fluid during production, it can maintain the surface friction coefficient and volume stability.
[0075] Further, please refer to Figures 1 to 5 As a specific embodiment of the bonding mechanism provided by this utility model, it further includes: a second station 12, a moving table 41, a transfer mechanism 42, a conveying channel 411, and a pressing mechanism 43; the second station 12 is used to place the workpiece 6; the second station 12 is set on the frame 1; the transfer mechanism 42 is used to move the moving table 41; the conveying channel 411 is used to convey the workpiece 52 to be bonded to the surface of the workpiece 6 in the second station 12; the conveying channel 411 is set on the moving table 41; the pressing mechanism 43 is used to press the workpiece 52 to be bonded onto the workpiece 6 in the second station 12; the pressing mechanism 43 is set on the moving table 41. Thus, the part to be pasted 52 is conveyed along the conveying channel 411. When the part to be pasted 52 is conveyed to the predetermined pasting surface on the workpiece 6, the pressing mechanism 43 can press the part to be pasted 52 onto the workpiece 6. The conveying channel 411 and the pressing mechanism 43 are respectively set on the moving table 41. Both the conveying channel 411 and the pressing mechanism 43 can move their positions with the moving table 41. The user can transfer the workpiece 6 with the part to be pasted 52 pasted on the second station 12 to the first station 11 for pressing.
[0076] Furthermore, the transfer mechanism 42 drives the moving table 41 to transport the part to be pasted 52 to the second station 12, where the pressing mechanism 43 takes over and performs the operation, creating a pressing method after pasting. This effectively shortens the waiting time between processes and increases production capacity. Additionally, the pressing mechanism 43 is located on the moving table 41, meaning that pasting and pressing can be performed immediately after the transfer mechanism 42 finishes moving. This smooth cycle of "moving, positioning, and pressing simultaneously" reduces the ineffective travel of the device, allowing the lifting drive mechanism and the pressing mechanism 43 to work together, further maximizing device utilization. Furthermore, the conveying channel 411 is located on the moving table 41, enabling "path variability" by adjusting the stopping point of the moving table 41 according to different products, thereby flexibly changing the relative pasting area between the part to be pasted 52 and the workpiece 6 without modifying the frame 1.
[0077] In one embodiment, the transfer mechanism 42 is mounted on the frame 1.
[0078] In one embodiment, the transfer mechanism 42 includes: a second X slide rail 421 disposed on the frame 1, a second X slide table 422 slidably disposed on the second X slide rail 421, a second X drive unit 423 for driving the second X slide table 422 to slide, a second Z slide rail 424 disposed on the second X slide table 422, a second Z slide table 425 slidably disposed on the second Z slide rail 424, and a second Z drive unit 426 for driving the second Z slide table 425 to slide; and a moving stage 41 disposed on the second Z slide table 425.
[0079] In one embodiment, the second X drive unit 423 is a motor or a telescopic cylinder.
[0080] In one embodiment, the second Z-drive unit 426 is a motor or a telescopic cylinder.
[0081] Further, please refer to Figures 1 to 5 As a specific embodiment of the bonding mechanism provided by this utility model, the pressing mechanism 43 includes: a power cylinder 431 with a telescopic part 4311 and a roller 432; the roller 432 is rotatably mounted on the telescopic part 4311. Thus, when the roller 432 extends or retracts, it can abut against the part 52 to be bonded, and when the moving table 41 drives the roller 432 to move, the roller 432 can roll and press the part 52 to be bonded at the same time.
[0082] Furthermore, the power cylinder 431, serving as the power source for the pressing mechanism 43, can output a stable and controllable linear thrust. Additionally, the telescopic part 4311, located at the end of the power cylinder 431, can extend or retract in real time with the piston stroke, thus automatically compensating for the thickness tolerance of the workpiece 6 on the second station 12: when the part to be bonded 52 first contacts the surface of the workpiece 6, the remaining stroke of the telescopic part 4311 can continue to output a constant thrust, keeping the roller 432 under controlled pressure. Furthermore, during the pressing process, the roller 432 rotates freely around its own axis, forming pure rolling contact with the surface of the part to be bonded 52 to minimize shear friction and prevent the part to be bonded 52 from being stretched, wrinkled, or slipping relative to the surface.
[0083] Further, please refer to Figures 1 to 5As a specific embodiment of the bonding mechanism provided by this utility model, it further includes: adhesive tape 51, a feeding wheel 45, a separating member, a take-up wheel 44, and a motor; the adhesive tape 51 is used for placing the part 52 to be bonded; the adhesive tape 51 can be conveyed along the conveying channel 411; the feeding wheel 45 is used for winding the adhesive tape 51 with the part 52 to be bonded; the feeding wheel 45 is rotatably mounted on the moving table 41; the separating member is used to separate the part 52 to be bonded and the adhesive tape 51; the separating member is mounted on the moving table 41 at the outlet of the conveying channel 411; the take-up wheel 44 is rotatably mounted on the moving table 41; the adhesive tape 51 on the feeding wheel 45 is conveyed along the conveying channel 411 and after passing through the separating member, it is wound around the take-up wheel 44; the motor is used to drive the take-up wheel 44 to rotate. Thus, the part to be bonded 52 can be conveyed together with the adhesive tape 51. The adhesive tape 51 is wrapped around the take-up pulley 44. When the take-up pulley 44 rotates, it can pull the adhesive tape 51 to move. After the part to be bonded 52 arrives at the separator along the conveying channel 411 with the adhesive tape 51, the part to be bonded 52 and the adhesive tape 51 can be separated from each other by the separator. The separated adhesive tape 51 can be stored on the take-up pulley 44. The separated part to be bonded 52 can be attached to the workpiece 6 at the second station 12.
[0084] Furthermore, the adhesive tape 51, feeding roller 45, take-up roller 44, and motor work together to automatically convey the adhesive tape 51 with the part to be bonded 52. The part to be bonded 52 is pre-bonded onto the adhesive tape 51. When the bonding mechanism is working, the adhesive tape 51 moves along the conveying channel 411 towards the separator via the feeding roller 45. Finally, under the action of the separator, the part to be bonded 52 is separated from the adhesive tape 51, and the remaining adhesive tape 51 is wound onto the take-up roller 44. The motor drives the take-up roller 44 to rotate, realizing the continuous movement of the adhesive tape 51 and the automatic recycling of waste tape, significantly improving the automation level of the bonding process, reducing manual operation, and increasing production efficiency. In addition, the coordinated arrangement of the feeding roller 45, take-up roller 44, and moving table 41 makes the entire bonding mechanism's feeding, separation, and recycling process highly integrated, with a compact structure, facilitating overall assembly and handling. In addition, the electric motor directly drives the take-up pulley 44 to rotate, which allows for precise control of the rotation speed of the take-up pulley 44, thereby adjusting the moving speed of the adhesive backing belt 51.
[0085] In one embodiment, the part to be bonded 52 can be directly conveyed to the desired bonding position on the workpiece 6 along with the adhesive tape 51.
[0086] In one embodiment, the system further includes a transport channel 412 disposed on a moving platform 41 for conveying the adhesive tape 51. One end of the transport channel 412 is connected to the space where the take-up pulley 44 is located, and the other end of the transport channel 412 is connected to the conveying channel 411. Thus, when the adhesive tape 51 (on which the workpiece 52 is adhered) reaches the intersection of the transport channel 412 and the conveying channel 411, the adhesive tape 51 enters the transport channel 412, and the workpiece 52 continues to be conveyed along the conveying channel 411, thereby separating the workpiece 52 from the adhesive tape 51.
[0087] In one embodiment, a separator is provided at the intersection of the conveying channel 411 and the transport channel 412, and the separator is connected to the moving table 41. The separator cuts between the part to be bonded 52 and the adhesive tape 51, so that the part to be bonded 52 and the adhesive tape 51 can be separated by the separator after they reach the intersection. The separated part to be bonded 52 continues to be conveyed along the conveying channel 411, and the separated adhesive tape 51 continues to be conveyed along the transport channel 412.
[0088] In one embodiment, the conveying channel 411 is a space, cavity, or groove of the moving stage 41.
[0089] In one embodiment, the transport channel 412 is a space, cavity, or slot of the mobile station 41.
[0090] In one embodiment, it further includes a drive motor disposed on the moving stage 41 and used to drive the backing tape 51 to move within the conveying channel 411.
[0091] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
