Description

Technical Field

[0001] This application relates to the field of hot-pressing coating, and more particularly to a hot-pressing apparatus. Background Technology

[0002] The hot pressing device is mainly used for laminating FFC products. Traditional FFC processing often employs manual feeding and single-layer, small-area hot pressing. Specifically, the FFC cables are manually placed one by one onto the conveyor station and then manually fed into the hot pressing equipment. The hot pressing equipment has a single-layer, small-area structure, and can only process a small number of FFCs at a time. The separate feeding and hot pressing processes result in low work efficiency, which needs to be improved. Summary of the Invention

[0003] In order to improve the problem of low work efficiency caused by the separate steps of feeding and hot pressing, this application provides a hot pressing device.

[0004] The hot pressing device provided in this application adopts the following technical solution: A hot pressing device includes a work frame and a feeding belt. The feeding belt is disposed on the work frame and is used to transport workpieces. A hot pressing zone is provided on one side of the feeding belt. A moving device is provided on the work frame and is used to move the workpieces between the feeding belt and the hot pressing zone. The hot pressing zone is used to hot press and coat the workpieces.

[0005] By adopting the above technical solution, the feeding belt can continuously transport the workpieces to be processed to the designated position, replacing manual loading. The moving device automatically transports the workpieces from the feeding belt to the hot pressing zone for coating processing, and then moves the workpieces back after processing. The entire loading, handling, and unloading process is automated, reducing manual intervention, which not only reduces labor intensity and operational risks, but also significantly improves production efficiency and the consistency of coating quality.

[0006] Optionally, the hot pressing zone includes a movable table, a movable plate, and a worktable arranged sequentially from top to bottom on the work frame. Hot pressing plates are installed at the bottom of the movable table, the upper and lower parts of the movable plate, and the top of the worktable. A film is connected to the movable table, the movable plate, and the worktable through an unwinding mechanism. The film covers the hot pressing plates. The work frame is provided with a driving assembly for driving the movable table and the movable plate to move up and down. The moving device can deliver the workpiece between the movable table and the movable plate, and between the movable plate and the worktable.

[0007] By adopting the above technical solution, after the moving device feeds the two workpieces into the upper and lower pressing spaces respectively, the drive component drives the movable table and movable plate to press down, so that the movable plate presses against the worktable, and the movable table presses against the movable plate. At this time, both workpieces are pressed together by the upper and lower hot press plates through the film, and the double-sided film coating of two workpieces can be completed in one action, which greatly improves the processing efficiency compared with single-station single-sided film coating.

[0008] Optionally, the drive assembly includes a hydraulic cylinder, a connecting rod, and a limiting block. The hydraulic cylinder is located at the top of the work frame, and its output end is connected to the movable platform to drive the movable platform to move up and down. The connecting rod is vertically arranged, passes through the movable platform, and can move vertically on the movable platform. The bottom end of the connecting rod is fixed to the movable plate. The limiting block is sleeved on the connecting rod and fixed to the connecting rod. The limiting block is located above the movable platform and can abut against the top wall of the movable platform.

[0009] By adopting the above technical solution, the hydraulic cylinder drives the movable platform to move downward. Under the action of gravity, the limiting block rests on the movable platform, causing the movable plate to move downward synchronously. After the movable plate presses against the worktable, the movable platform continues to move downward, causing it to slide on the connecting rod. The limiting block moves upward relative to the movable platform and separates from it until the movable platform and the movable plate come into contact. This achieves mutual pressing of the movable platform, the movable plate, and the worktable, ensuring the uniformity and stability of the pressing force and simplifying the control logic and structure.

[0010] Optionally, a support platform is provided between the feeding belt and the hot pressing zone, and a flipping mechanism is provided between the support platform and the feeding belt. The flipping mechanism is used to transport the workpiece between the feeding belt and the support platform. A conveying device is provided on the work frame, and the conveying device is used to transport the workpiece between the heating zone and the support platform.

[0011] By adopting the above technical solution, the introduction of the flipping mechanism enables the workpiece to be automatically flipped and transferred between the feeding belt and the support table. The conveying device is responsible for unloading the finished workpiece between the hot pressing zone and the support table. The moving device works in conjunction with the flipping mechanism to complete the loading of the workpiece to be processed, forming an efficient transfer and connection system, which lays the foundation for the subsequent realization of full-station parallel operation.

[0012] Optionally, the work frame is equipped with a conveyor belt, which is located on the side of the feeding belt away from the hot pressing zone and is parallel to the feeding belt. The moving device includes a lifting platform and two moving components. The lifting platform is slidably connected to the work frame and connected to the two moving components to drive the moving components to move up and down. One of the moving components is used to transport the workpiece on one side of the flipping mechanism to the conveyor belt, and the other moving component is used to transport the workpiece on the other side of the flipping mechanism to the hot pressing zone.

[0013] By adopting the above technical solution, the two moving components can work independently or synchronously. One is responsible for picking up unprocessed workpieces (the flipping mechanism) and sending them to the hot pressing zone, while the other is responsible for removing processed workpieces from the flipping mechanism and sending them to the conveyor belt. With the synchronous flipping of the flipping mechanism, the picking up of new materials and the unloading of old materials can be carried out simultaneously, eliminating waiting time and maximizing work efficiency.

[0014] Optionally, the moving component includes a bracket, a moving part, and a moving suction cup. The bracket is connected to the lifting platform, the moving part is slidably connected to the bracket, and the moving suction cup is disposed on the moving part. The moving part is used to drive the moving suction cup to move horizontally, and the moving suction cup is used to adsorb the workpiece.

[0015] By adopting the above technical solution, the moving component drives the moving suction cup to move above the workpiece. Then, the lifting platform is activated, driving the bracket to move down so that the moving suction cup can contact the workpiece and hold it in place. The lifting platform drives the bracket to move up so that the moving suction cup lifts the workpiece. The moving component drives the moving suction cup to move horizontally and transport the workpiece to the designated position.

[0016] Optionally, the movable component includes a movable rod and a movable seat, the movable seat being fixed on the bracket, the movable rod being embedded in the movable seat, and the movable rod being movable on the movable seat.

[0017] By adopting the above technical solution, when the movable suction cup needs to be translated, the moving rod is driven to move, so that the moving rod slides on the moving seat. The moving seat plays a limiting and guiding role, so that the moving rod moves along its own length direction, thereby realizing the translation of the movable suction cup.

[0018] Optionally, the flipping mechanism includes a mounting base, a rotating motor, and a rotating plate. The mounting base is disposed on the work frame and is located between the feeding belt and the support table. The rotating motor is disposed on the mounting base, and its output end is fixed to one end of the rotating plate to drive the rotating plate to flip. Both sides of the rotating plate are provided with fixed suction cups for adsorbing workpieces. The rotating plate can rotate to a horizontal position above the feeding belt or the support table.

[0019] By adopting the above technical solution, in the initial state, the rotating plate is horizontally located above the feeding belt. The fixed suction cup on the back of the rotating plate adsorbs the unprocessed workpiece on the feeding belt. Then, the rotating motor drives the rotating plate to rotate 180° until the rotating plate is horizontally located above the support platform. At this time, the back of the rotating plate is facing up, that is, the adsorbed unprocessed workpiece is facing up. Then, the moving suction cup on one of the moving components adsorbs the workpiece on the back of the rotating plate and moves it to the hot pressing area.

[0020] When the rotating plate is on the support platform, the front of the rotating plate faces down and is aligned with the support platform. At this time, the support platform holds the processed workpieces that have been transported from the hot pressing area by the conveying device. The fixed suction cup on the front of the rotating plate adheres to the processed workpieces on the support platform.

[0021] During the process of the moving components transporting the workpiece to the hot pressing zone, the rotating plate, adsorbing the processed workpiece, returns to its original position above the feed belt. At this point, the front of the rotating plate faces upwards again, and the back faces downwards again, adsorbing new unprocessed workpieces from the feed belt below. Simultaneously, the other moving component moves synchronously. When one moving component reaches the hot pressing zone and places a workpiece, the other moving component moves above the feed belt. At this point, the rotating plate is also above the feed belt, positioned between the feed belt and the moving suction cup. The moving suction cup aligns with the front of the rotating plate and adsorbs the processed workpiece on it, subsequently moving towards the conveyor belt.

[0022] During this process, the conveying device delivers the processed workpieces from the hot pressing zone to the support platform. The reverse side of the rotating plate picks up unprocessed workpieces and flips them over onto the support platform, with one side of the rotating plate facing upwards and the other side facing downwards, picking up workpieces from the support platform. Simultaneously, another moving component returns from the hot pressing zone and moves towards the support platform. When one moving component reaches the conveyor belt to place a workpiece, the other moving component reaches the support platform to pick up workpieces from the rotating plate. This process is repeated to complete fully automated workpiece processing. The rotating plate simultaneously loads and unloads from both sides, and the conveying device completes unloading from the hot pressing zone during the rotating plate's flipping process. While the rotating plate is flipping, a feeding belt moves new workpieces to the rotating plate for loading. Throughout the entire process, no station is idle, achieving full-station operation and improving work efficiency.

[0023] Optionally, the workbench is equipped with a detection mechanism, which includes a front detection device and a back detection device. The front detection device is located directly above the support platform and is used to detect the workpiece on the support platform. The back detection device is located directly above the conveyor belt and is used to detect the workpiece on the conveyor belt.

[0024] By adopting the above technical solution, when the conveying device delivers the workpiece from the hot pressing zone to the support table, the front side of the workpiece faces upward, and the front detection device checks whether the workpiece is properly coated. When the rotating plate adsorbs the workpiece on the support table and flips it over to the top of the feeding belt, one of the moving components delivers the workpiece to the conveyor belt. After the workpiece is reversed by the rotating plate, the back side of the workpiece faces upward, that is, the back side of the workpiece on the conveyor belt faces upward. Then, the back detection device is used to detect whether the back side of the workpiece is properly coated, thereby realizing double-sided detection of the workpiece.

[0025] Optionally, the conveying device includes a sliding frame, a sliding rod, and a sliding suction cup. The sliding frame is mounted on the work frame and can move vertically on the work frame. The sliding rod is slidably connected to the sliding frame and can move horizontally toward or away from the support platform. The sliding suction cup is mounted on the sliding rod.

[0026] By adopting the above technical solution, the conveying device itself has the ability to lift and move horizontally, and can independently and accurately move workpieces between the hot pressing zone and the support table.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. Through the coordinated operation of the feeding belt, moving device, tilting mechanism, handling device, and conveyor belt, the entire process of workpiece feeding, tilting, handling, hot pressing, and discharging is fully automated. In particular, the design of the front and back suction cups of the tilting mechanism and the cooperation of two moving components enable the parallel processing of multiple actions such as loading and unloading, new material transportation, and old material unloading, achieving full-station operation and greatly improving production efficiency. 2. Front and back detection devices are installed on the support platform and conveyor belt respectively. By utilizing the two postures that the workpiece will inevitably pass through in the process, namely front facing up and back facing up, the double-sided automatic detection of the hot pressing and coating effect is realized without adding extra flipping action. Defective products can be rejected in time, ensuring the quality consistency of the products leaving the factory. Attached Figure Description

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses a hot pressing device. (Refer to...) Figure 1 and Figure 2 The hot pressing device includes a work frame 1 and a feeding belt 2. The feeding belt 2 is mounted on the work frame 1 and is used to transport the workpiece to be processed. There are two feeding belts 2 that are not arranged vertically. A hot pressing zone 3 is provided on one side of the feeding belt 2 for hot pressing and coating the workpiece. The work frame 1 is also equipped with a moving device 4 for transporting the workpiece between the feeding belt 2 and the hot pressing zone 3.

[0032] Reference Figure 1 and Figure 2 Specifically, the hot pressing zone 3 includes a movable table 31, a movable plate 32, and a worktable 33 arranged sequentially from top to bottom on the work frame 1. Hot pressing plates 34 are installed on the bottom of the movable table 31, the upper and lower surfaces of the movable plate 32, and the top of the worktable 33. A film 36 is connected to the movable table 31, the movable plate 32, and the worktable 33 via an unwinding mechanism 35. The film 36 covers the surface of the corresponding hot pressing plate 34, isolating the workpiece from the hot pressing plate 34, and providing a coating material. The moving device 4 can transport the workpieces from the upper and lower layers between the movable table 31 and the movable plate 32, and between the movable plate 32 and the worktable 33, respectively.

[0033] Reference Figure 1 and Figure 2To achieve pressing, a drive assembly 5 is provided on the work frame 1. The drive assembly 5 includes a hydraulic cylinder 51, a connecting rod 52, and a limiting block 53. The hydraulic cylinder 51 is fixed to the top of the work frame 1, and its output end is connected to the top of the movable table 31. The connecting rod 52 is vertically arranged and passes through the movable table 31. The movable table 31 has a through hole for the connecting rod 52 to pass through, so that the connecting rod 52 can move vertically within the through hole. The bottom end of the connecting rod 52 is fixedly connected to the movable plate 32. The limiting block 53 is sleeved and fixed on the connecting rod 52, located above the movable table 31, and its lower surface can abut against the top wall of the movable table 31.

[0034] Reference Figure 1 and Figure 2 After the moving device 4 feeds the two workpieces into the upper and lower pressing spaces respectively, the hydraulic cylinder 51 drives the movable table 31 to move downwards. Under the action of gravity, the limiting block 53 rests on the movable table 31, causing the movable plate 32 to move downwards synchronously. When the movable plate 32 presses against the worktable 33, the movable table 31 continues to move downwards, causing it to slide on the connecting rod 52. The limiting block 53 moves upwards relative to the movable table 31 and separates from it until the movable table 31 abuts against the movable plate 32, thus achieving mutual pressing of the movable table 31, the movable plate 32, and the worktable 33. At this time, both workpieces are pressed together by the upper and lower hot press plates 34 through the film 36. Double-sided film coating of two workpieces can be completed in one action, which greatly improves processing efficiency compared to single-station single-sided film coating.

[0035] Reference Figure 1 and Figure 3 A support platform 6 is provided between the feeding belt 2 and the hot pressing zone 3. A tilting mechanism 7 is provided between the support platform 6 and the feeding belt 2 for transporting the workpiece between them. At the same time, a conveying device 8 is provided on the work frame 1 for transporting the workpiece between the hot pressing zone 3 and the support platform 6.

[0036] Reference Figure 1 and Figure 3 The work frame 1 is also equipped with a conveyor belt 9, which is located on the other side of the feeding belt 2, i.e., the side away from the hot pressing zone 3, and is parallel to the feeding belt 2. The moving device 4 includes a lifting platform 41 and two moving components 42. The lifting platform 41 is slidably connected to the work frame 1 and can move up and down. The two moving components 42 are arranged side by side on the lifting platform 41 and are driven by the lifting platform 41 to move up and down synchronously. One of the moving components 42 is used to transport the workpiece on one side (e.g., the front) of the flipping mechanism 7 to the conveyor belt 9; the other moving component 42 is used to transport the workpiece on the other side (e.g., the back) of the flipping mechanism 7 to the hot pressing zone 3.

[0037] Reference Figure 1 and Figure 3Each movable component 42 includes a bracket 421, a movable element 422, and a movable suction cup 423. The bracket 421 is fixedly connected to the lifting platform 41. The movable element 422 is slidably connected to the bracket 421. The movable suction cup 423 is mounted on the movable element 422. The movable element 422 further includes a movable rod 4221 and a movable seat 4222. The movable seat 4222 is fixed to the bracket 421, and the movable rod 4221 is embedded in the movable seat 4222 and can move horizontally under the drive of the hydraulic cylinder 51 or a motor. The movable suction cup 423 is mounted on the end of the movable rod 4221.

[0038] Reference Figure 1 and Figure 3 The flipping mechanism 7 includes a mounting base 71, a rotary motor 72, and a rotating plate 73. The mounting base 71 is fixed on the work frame 1, located between the feed belt 2 and the support table 6. The output end of the rotary motor 72 is fixedly connected to one end of the rotating plate 73, and is used to drive the rotating plate 73 to flip. Multiple suction cups 74 for adsorbing workpieces are provided on both sides of the rotating plate 73. In the initial state or after flipping, the rotating plate 73 can remain horizontal and is positioned directly above the feed belt 2 or the support table 6.

[0039] Reference Figure 1 and Figure 3 In the initial state, the rotating plate 73 is horizontally positioned above the feeding belt 2. The fixed suction cup 74 on the reverse side of the rotating plate 73 adsorbs the unprocessed workpiece on the feeding belt 2. Then, the rotating motor 72 drives the rotating plate 73 to rotate 180° until the rotating plate 73 is horizontally positioned above the support platform 6. At this time, the reverse side of the rotating plate 73 faces upward, that is, the unprocessed workpiece is adsorbed upward. Then, the moving suction cup 423 on one of the moving components 42 adsorbs the workpiece on the reverse side of the rotating plate 73 and moves it to the hot pressing zone 3.

[0040] When the rotating plate 73 is on the support platform 6, the front of the rotating plate 73 faces down and is aligned with the support platform 6. At this time, the support platform 6 holds the processed workpieces transported from the hot pressing zone 3 by the conveying device 8. The fixed suction cup 74 on the front of the rotating plate 73 adsorbs the processed workpieces on the support platform 6.

[0041] Reference Figure 1 and Figure 3During the process of the moving component 42 transporting the workpiece to the hot pressing zone 3, the rotating plate 73, adsorbing the processed workpiece, returns to above the feeding belt 2. At this time, the front of the rotating plate 73 faces upward again, and the back of the rotating plate 73 faces downward again, adsorbing new unprocessed workpieces on the feeding belt 2 below. While one moving component 42 moves, the other moving component 42 moves synchronously. When one moving component 42 moves to the hot pressing zone 3 and places a workpiece, the other moving component 42 moves above the feeding belt 2. At this time, the rotating plate 73 is also above the feeding belt 2, that is, the rotating plate 73 is located between the feeding belt 2 and the moving suction cup 423. The moving suction cup 423 is aligned with the front of the rotating plate 73 and adsorbs the processed workpiece on the rotating plate 73, and then moves to the conveyor belt 9. One side of the rotating plate 73 can release or pick up a workpiece, and the other side can simultaneously pick up or release another workpiece, realizing efficient "hand-changing" operation, which is the core link of full-station parallel operation.

[0042] During this process, the conveying device 8 delivers the processed workpieces from the hot pressing zone 3 to the support platform 6. The reverse side of the rotating plate 73 adsorbs the unprocessed workpieces and flips them over to the top of the support platform 6. The rotating plate 73 has one side facing upwards and the other side facing downwards, adsorbing the workpieces on the support platform 6. At the same time, another moving component 42 returns from the hot pressing zone 3 and moves towards the support platform 6. When one moving component 42 reaches the conveyor belt 9 to place a workpiece, the other moving component 42 reaches the top of the support platform 6 to adsorb the workpieces on the rotating plate 73. The above steps are repeated to complete the fully automated workpiece processing. The rotating plate 73 simultaneously loads and unloads from both sides, and the conveying device 8 completes the unloading of the hot pressing zone 3 during the rotation of the rotating plate 73. When the rotating plate 73 rotates, the feeding belt 2 also moves new workpieces to the rotating plate 73 to complete the loading. Throughout the entire process, no station is idle, achieving full-station operation and improving work efficiency.

[0043] Reference Figure 1 The conveying device 8 includes a sliding frame 81, a sliding rod 82, and a sliding suction cup 83. The sliding frame 81 is mounted on the work stand 1 and can move vertically up and down, for example, driven by a hydraulic cylinder 51. The sliding rod 82 is slidably connected to the sliding frame 81 and can move horizontally left and right to approach or move away from the support table 6 and the hot pressing zone 3. The sliding suction cup 83 is mounted at the end of the sliding rod 82 for adsorbing workpieces.

[0044] Reference Figure 1 and Figure 3The workbench 1 is also equipped with a detection mechanism 10, including a front detection device 101 and a back detection device 102. The front detection device 101, such as an industrial camera, is fixed directly above the support platform 6 and is used to detect the coating quality of the front side of the workpiece on the support platform 6. The back detection device 102 is fixed directly above the conveyor belt 9 and is used to detect the coating quality of the back side of the workpiece on the conveyor belt 9.

[0045] The implementation principle of the hot pressing device in this embodiment is as follows: First, the feeding belt 2 delivers the workpiece to be processed to a position close to the flipping mechanism 7. At this time, the rotating plate 73 of the flipping mechanism 7 is in a horizontal position, directly above the feeding belt 2, and the fixed suction cup 74 on the back of the rotating plate 73 faces downward, adsorbing the unprocessed workpiece on the feeding belt 2. Subsequently, the rotating motor 72 starts, driving the rotating plate 73 to rotate 180°, so that it is horizontally positioned directly above the support table 6. The conveying device 8 operates synchronously, extending its sliding suction cup 83 into the hot pressing zone 3, adsorbing the finished workpiece that has been double-sided coated in the previous round, and removing it from the hot pressing zone 3 and placing it on the support table 6. At this time, the rotating plate 73 with the unprocessed workpiece adsorbed faces upward, while its front faces downward, aligned with the support table 6.

[0046] Meanwhile, the moving component 42 of the hot pressing zone 3 works: its moving suction cup 423 moves to above the support table 6 under the drive of the moving component 422, the lifting table 41 descends so that the suction cup contacts and adsorbs the unprocessed workpiece on the reverse side of the rotating plate 73, then the lifting table 41 rises to lift it up, and the moving component 422 then transports the workpiece to the space between the movable plate 32 and the worktable 33 in the hot pressing zone 3, or between the movable table 31 and the movable plate 32.

[0047] When the finished workpiece is placed on the support platform 6 with its front side facing up, the front detection device 101 detects it. At this time, the fixed suction cup 74 on the front of the rotating plate 73 faces down, aligning perfectly with the finished workpiece on the support platform 6, and immediately adsorbs it. Then, the rotating motor 72 starts again, driving the rotating plate 73 to flip the finished workpiece back above the feed belt 2. During the flipping process, the reverse side of the rotating plate 73 faces down again and adsorbs a new unprocessed workpiece fed from the feed belt 2.

[0048] Once the rotating plate 73 is stable above the feeding belt 2, the moving component 42 of the conveyor belt 9 activates: its moving suction cup 423 moves above the rotating plate 73, adsorbs the finished workpiece facing upwards on the front of the rotating plate 73, and transports it onto the conveyor belt 9. On the conveyor belt 9, the reverse side of the workpiece faces upwards, and the reverse side detection device 102 detects it. Meanwhile, the moving component 42 of the hot pressing zone 3 returns from the hot pressing zone 3, ready to adsorb newly adsorbed unprocessed workpieces on the reverse side of the rotating plate 73, and send them back to the hot pressing zone 3 for processing. This completes one work cycle.

[0049] Throughout the process, the flipping mechanism 7, the two moving components 42 and the conveying device 8 work together closely to achieve fully automated production line operation of the workpiece from feeding, flipping, loading, pressing, unloading to inspection, with no idle workstations, which greatly improves production efficiency.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
