Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, and in particular to an integrated production line for the automatic assembly of corks for flat workpieces. The production line is used to realize the integrated production of automatic glue dispensing, cork assembly and pressure holding for flat workpieces. Background Technology

[0002] Drilling holes directly into aluminum honeycomb panels and screwing in screws is not feasible because the interior is hollow and cannot provide sufficient support for the screws. Wooden plugs are needed to increase strength, and the screws are then screwed into the wooden plugs. Therefore, wooden plugs must be installed in the holes of the aluminum honeycomb panels. Currently, there are two main methods for installing wooden plugs on flat workpieces: one is a semi-automatic manual method, where a person applies glue using a handheld dispensing gun, then manually or with the aid of a simple cylinder, presses in the wooden plug, and finally places it in an independent pressure-holding fixture for curing; the other is a single-process automated method, using a separate three-axis dispensing machine, pressing machine, and pallet holding rack, but manual handling of the workpiece is still required between processes. Neither of these methods achieves continuous operation of the dispensing, plugging, and pressure-holding processes.

[0003] The aforementioned existing technologies have the following drawbacks: low production efficiency, high reliance on manual labor, and poor consistency between dispensing and pressing, resulting in low yield; discrete processes, requiring multiple manual handling of workpieces, which can easily cause bumps and premature curing of the adhesive; poor equipment versatility, resulting in high modification costs when changing to products of different sizes; in addition, the lack of a continuous pressure holding mechanism, which makes the wooden stopper prone to springing back during the adhesive curing process, leading to sealing failure.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present application or its application or use. Example 1

[0020] like Figure 1As shown, this embodiment provides an integrated production line for automatic assembly of corks for flat workpieces, including: a base 1, on which a conveying mechanism 2 is provided. The conveying mechanism 2 is arranged sequentially along the conveying direction of the workpiece with a manual feeding station, an automatic dispensing station, an automatic cork loading station, and a cork pressure holding station. Each station is equipped with a positioning fixture 3 for positioning the workpieces conveyed by the conveying mechanism 2. The positioning fixture 3 of the automatic dispensing station is equipped with a servo dispensing module 4 for automatically dispensing glue to the workpiece. The positioning fixture 3 of the automatic cork loading station is equipped with a cork servo transfer mechanism 5 for pressing the cork into the workpiece after dispensing. The positioning fixture 3 of the cork pressure holding station is equipped with an automatic pressure holding mechanism 6 for applying continuous pressure to the workpiece after the cork is pressed in for pressure holding and curing.

[0021] The production line is arranged in a straight line with a manual feeding station, an automatic dispensing station, an automatic cork-filling station, and a cork-holding station. The spacing between each station is adapted to the stroke of the conveyor mechanism 2. The overall cycle time is 45 seconds per set. The four stations, in conjunction with the conveyor mechanism 2, can process four workpieces simultaneously. Each station is equipped with an independent positioning fixture 3 to position and fix the workpiece. All modules on the production line are mounted on the base 1 and are linked through an electrical control system. First, the worker places the workpiece into the positioning fixture 3 at the manual feeding station; then, the conveyor mechanism 2 transports the workpiece from the feeding station to the automatic dispensing station; the servo dispensing module 4 completes the dispensing of adhesive into the holes on the workpiece surface according to a preset path; after dispensing, the workpiece is transported to the automatic cork-filling station; the cork servo transfer mechanism 5 accurately presses the cork into the dispensed workpiece; after pressing, the workpiece is transported to the cork-holding station; the automatic pressure-holding mechanism 6 applies continuous pressure to the cork for pressure holding; after pressure holding, the finished workpiece is manually removed and enters the next batch cycle. This means that by using a multi-station continuous flow design, manual dispensing, pressing, and handling processes can be replaced, achieving full-process automation and significantly improving production efficiency.

[0022] like Figure 2 As shown, the conveying mechanism 2 includes a linear guide rail 21, a horizontal transfer cylinder 22, and a moving module 7. The linear guide rail 21 is fixedly connected to the base 1, the horizontal transfer cylinder 22 is fixedly connected to the base 1, and there are three moving modules 7. The output end of the horizontal transfer cylinder 22 is connected to the sliding plate 23 of one of the moving modules 7, and the other two moving modules 7 are connected to the moving module 7 connected to the horizontal transfer cylinder 22 through the connecting block 28, so that the three moving modules 7 move synchronously back and forth along the linear guide rail 21 between four workstations under the drive of the horizontal transfer cylinder 22.

[0023] The horizontal transfer cylinder 22 serves as the main power source for the conveying mechanism 2, driving the moving module 7 to move on the linear guide rail 21, thereby causing the workpieces on the moving module 7 to flow between multiple workstations. The moving module 7 is used to carry the workpieces, and the three moving modules 7 are fixed together by the connecting block 28. In this way, only one horizontal transfer cylinder 22 is needed to drive the three moving modules 7 to move synchronously. The distance between the three moving modules 7 is adapted to the distance between each workstation, which can accurately position them between each workstation, transport the workpiece from the previous workstation to the next workstation, realize the continuous flow of workpieces, and greatly improve the flow efficiency.

[0024] like Figure 3 As shown, the moving module 7 includes a slider 24, a lifting cylinder 25, and a transport carrier 26. The slider 24 is slidably connected to the linear guide rail 21, the sliding plate 23 is fastened to the slider 24, the lifting cylinder 25 is fastened to the sliding plate 23, the output end of the lifting cylinder 25 is connected to the transport carrier 26, and the transport carrier 26 is provided with a pneumatic suction cup 27 and a first sensor 29.

[0025] The sliding plate 23 slides on the linear guide rail 21 via the slider 24. During operation, when the process at a certain station is completed, the first sensor 29 triggers a signal, and the conveying mechanism 2 starts working. The lifting cylinder 25 drives the transport carrier 26 to rise, so that the pneumatic suction cup 27 picks up the workpiece and drives the workpiece to rise and leave the positioning fixture 3 at this station. Then, the horizontal transfer cylinder 22 drives the transport carrier 26 to the next station, the pneumatic suction cup 27 puts down the workpiece, and the lifting cylinder 25 drives the transport carrier 26 to fall, completing the transfer between stations and forming continuous production.

[0026] like Figure 4 As shown, the positioning fixture 3 is arranged on both sides of the conveying mechanism 2. The positioning fixture 3 includes a base plate 31, which is fastened to the machine base 1. Several positioning blocks 32 are detachably installed on the base plate 31. The positioning area composed of the several positioning blocks 32 matches the outer contour of the workpiece. A second sensor 33 is provided on the base plate 31.

[0027] The base of the substrate 31 is fixed to the machine base 1. The substrate 31 is provided with several mounting holes. Several positioning blocks 32 can be freely combined according to the shape of the workpiece to form a positioning area that matches the outer contour of the workpiece. The second sensor 33 is used to detect whether the workpiece is in place.

[0028] like Figure 5 As shown, the servo dispensing module 4 includes a first three-axis servo mechanism 41. The base of the first three-axis servo mechanism 41 is fastened to the base 1. A dispensing gun 42 is installed at the Z-axis end of the first three-axis servo mechanism 41.

[0029] The first three-axis servo mechanism 41 is a gantry-type three-axis servo structure, consisting of X-axis, Y-axis, and Z-axis linear modules and servo motors, with a dispensing gun 42 mounted at the end of the Z-axis. During operation, the first three-axis servo mechanism 41 can drive the dispensing gun 42 to achieve high-precision movement in the X / Y / Z directions, automatically applying glue to the wooden plug installation position on the workpiece surface according to a preset dispensing path. After the workpiece is transported to the positioning fixture 3 at this station by the conveying mechanism 2, the second sensor 33 is triggered, and the servo dispensing module 4 completes the dispensing according to the preset program. After dispensing is completed, it waits for the conveying mechanism 2 to transport it to the next station.

[0030] like Figure 6 As shown, the wood plug servo transplanting mechanism 5 includes a second three-axis servo mechanism 51, and a wood plug loading mechanism 52 is installed at the Z-axis end of the second three-axis servo mechanism 51.

[0031] The second and third axis servo mechanism 51 is a gantry-type three-axis servo structure. The second and third axis servo mechanism 51 drives the wood plug loading mechanism 52 to move above the workpiece. The wood plug is screened by a vibratory plate and sent to the wood plug loading mechanism 52 by air blowing through the conveying pipe. The pressing depth and speed are controlled by the Z-axis servo to accurately press the wood plug into the position after the glue is applied on the workpiece.

[0032] like Figures 7-9 As shown, the cork-loading mechanism 52 includes a base plate 521 and a solenoid valve 522. The base plate 521 is connected to the Z-axis end of the second three-axis servo mechanism 51. The solenoid valve 522 is connected to the base plate 521 and is externally connected to an air source. The base plate 521 is equipped with a pen-shaped cylinder 523, a guide block 525, a thin cylinder 527, and a conveying pipe 53. The solenoid valve 522 is connected to the pen-shaped cylinder 523 and the thin cylinder 527. The output end of the pen-shaped cylinder 523 is equipped with a push rod 524, and the output end of the thin cylinder 527 is equipped with a push block 526. The feed inlet of the conveying pipe 53 is externally connected to a feeding mechanism. The guide block 525 is equipped with a feeding mechanism. Channel 5251, guide channel 5252, discharge channel 5253 and chute 5254 are connected to each other. The discharge port of the conveying pipe 53 is connected to the feed channel 5251. Push block 526 is slidably connected to guide channel 5252. Push rod 524 is slidably connected to discharge channel 5253. An auxiliary block 528 is slidably connected in chute 5254. A return spring 529 is provided in chute 5254. One end of return spring 529 is connected to auxiliary block 528 and the other end of return spring 529 is connected to inner wall of chute 5254.

[0033] The base plate 521 is fixed on the Z-axis of the second and third-axis servo mechanism 51, providing a mounting base for the wood plug loading mechanism 52. The solenoid valve 522 is used to control the action of the pen-shaped cylinder 523 and the thin cylinder 527. When loading the wood plug, the wood plug falls into the feeding channel 5251 through the conveying pipe 53. After the sensor on one side of the feeding channel 5251 detects the wood plug entering, the thin cylinder 527 is activated, driving the push block 526 to move, so that the wood plug moves along the guide channel 5252 to the discharge channel 5253. When the wood plug moves, the auxiliary block 528 is pressed and moves along the slide groove 5254. The return spring 529 is compressed by force. The return spring 529 and the auxiliary block 528 cooperate to limit the wood plug and prevent the wood plug from tilting. After the wood plug reaches the discharge channel 5253, the sensor on the side of the discharge channel 5253 detects that the wood plug is in place, and the pen-shaped cylinder 523 is activated, driving the push rod 524 to move down and press the wood plug into the hole on the workpiece.

[0034] like Figure 10 As shown, the automatic pressure holding mechanism 6 includes a mounting column 61, an upper mounting plate 62, a pressure holding cylinder 63, and a ball guide column 64.

The upper mounting plate 62 is provided with a buffer 66, and the buffer head of the buffer 66 faces the pressure plate 65.

[0035] Mounting column 61 is fixed on base 1 to provide mounting foundation for automatic pressure holding mechanism 6. Ball guide column 64 provides guidance for pressing plate 65. Buffer 66 is used to protect pressing plate 65. After pressing, the workpiece is transported to the wooden plug pressure holding station and placed in positioning fixture 3 that matches the workpiece. After triggering second sensor 33, pressure holding cylinder 63 drives pressing plate 65 to press down and apply set pressure to wooden plug. After the set pressure holding time, pressure holding cylinder 63 resets and finished workpiece is manually removed. Example 2
