The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, an ACF hot pressing device for an automatic hot pressing equipment is provided. The device is installed on the automatic hot pressing equipment, which includes a base and a feeding mechanism that can transport the product to be processed onto the ACF hot pressing device.

[0023] The ACF hot pressing device includes a hot pressing support base 1. A feeding mechanism can transport the product to be processed onto the hot pressing support base 1. The hot pressing support base 1 is equipped with a hot pressing transverse module 2, and a hot pressing transverse slider 21 is provided on the output end of the hot pressing transverse module 2. The hot pressing transverse slider 21 is equipped with a hot pressing lifting module 3, a protection component 4, and a CCD positioning mechanism 5. A hot pressing head 6 is provided on the output end of the hot pressing lifting module 3. The CCD positioning mechanism 5 is used to capture an image of the product below the hot pressing head 6, so that the hot pressing head 6 can be accurately aligned with the hot pressing position of the product to be processed on the hot pressing support base 1. The hot pressing lifting module 3 is used to drive the hot pressing head 6 to move up and down, so as to bring the hot pressing head 6 into contact with or separate from the product on the hot pressing support base 1, thereby realizing the pressing operation. The protective component 4 is connected to the hot press head 6 and is used to lay a layer of isolation cloth 41 on the lower end surface of the hot press head 6, thereby preventing the hot press head 6 from directly contacting the product during hot pressing. This protects the product and prevents damage to the hot press head 6, extending its service life.

[0024] Before processing, the isolation cloth 41 on the protective component 4 is laid on the lower end surface of the hot press head 6. During processing, the feeding mechanism transports the product to be processed to the position on the hot press support 1 that aligns with the hot press head 6. The CCD positioning mechanism 5 acquires an image of the product to determine the position on the product that needs to be hot-pressed. Then, the hot press horizontal movement module 2 drives the hot press lifting module 3 to move the hot press head 6 directly above the pressing position. The hot press lifting module 3 then drives the hot press head 6 to descend until the hot press head 6, with the isolation cloth 41, comes into contact with the product for hot pressing. After hot pressing is completed, the hot press lifting module 3 and the hot press horizontal movement module 2 work together to drive the hot press head 6 to rise and return to its initial position.

[0025] Specifically, the hot-press traverse module 2 includes a hot-press traverse motor 22, which is fixedly connected to the hot-press support base 1. A hot-press traverse lead screw 23 is provided on the output end of the hot-press traverse motor 22. The hot-press traverse slider 21 is threadedly connected to the hot-press traverse lead screw 23 to achieve sliding. During operation, the hot-press traverse motor 22 drives the hot-press traverse lead screw 23 to rotate, thereby driving the hot-press traverse slider 21 to move the hot-press lifting module 3 laterally.

[0026] In order to limit and guide the movement direction of the hot-pressed transverse slider 21, two hot-pressed transverse guide rails 24 are provided in parallel on the hot-pressed support 1, and the hot-pressed transverse slider 21 is slidably engaged with the hot-pressed transverse guide rails 24 respectively; through the sliding engagement between the hot-pressed transverse slider 21 and the hot-pressed transverse guide rails 24, the movement of the hot-pressed transverse slider 21 can be ensured to be smooth.

[0027] like Figure 3 As shown, the hot press lifting module 3 includes a hot press lifting motor 31, which is fixedly connected to the hot press horizontal sliding block 21. A hot press lifting screw 32 is provided on the output end of the hot press lifting motor 31. A hot press lifting slider 33 is sleeved on the hot press lifting screw 32, and the hot press head 6 is connected to the hot press lifting slider 33. During operation, the hot press lifting motor 31 drives the hot press lifting screw 32 to rotate, which in turn drives the hot press lifting slider 33 to move the hot press head 6 up and down, causing the hot press head 6 to move towards or away from the product on the hot press support base 1.

[0028] In order to limit and guide the lifting and lowering movement of the hot press head 6, a hot press lifting guide rail 34 is provided on the hot press horizontal sliding slider 21. The hot press lifting slider 33 is slidably engaged with the hot press lifting guide rail 34 to ensure smooth lifting and lowering movement.

[0029] To precisely control the pressing pressure, a pressure sensor 7 is installed on the hot pressing lifting slider 33. The side of the pressure sensor 7 away from the hot pressing lifting slider 33 is connected to the hot pressing head 6. The pressure sensor 7 can monitor the pressing pressure in real time and feed the signal back to the control system to achieve pressure control, thereby improving the stability of hot pressing and ensuring the processing quality of the product.

[0030] A heat insulation block 8 is provided on the side of the pressure sensor 7 away from the hot-press lifting slider 33. A heating block 9 is provided on the side of the heat insulation block 8 away from the pressure sensor 7. The hot-press head 6 is fixedly connected to the heating block 9. The heating block 9 is equipped with a heating element (not shown in the figure), which is electrically connected to the control center of the automatic hot-press equipment. By supplying power to the heating element, the heating block 9 can be heated, and the heat will be conducted to the hot-press head 6, causing the hot-press head 6 to be heated to the required temperature. The heat insulation block 8 is used to prevent heat from being transferred to the pressure sensor 7 and other components, protecting the sensitive element.

[0031] like Figure 4As shown, the protective component 4 includes a protective cloth mounting frame 42, which is fixedly connected to the hot press transverse slider 21. The protective cloth mounting frame 42 is equipped with a protective cloth unwinding roller 43, a protective cloth take-up roller 44, and a protective cloth take-up motor 45. The protective cloth unwinding roller 43 and the protective cloth take-up roller 44 are rotatably connected to the protective cloth mounting frame 42. The protective cloth unwinding roller 43 is used to hold the rolled protective cloth 41. The protective cloth 41 on the protective cloth unwinding roller 43 can be stretched and laid sequentially onto the hot press head 6 and the protective cloth take-up roller 44. The output end of the protective cloth take-up motor 45 is connected to the protective cloth take-up roller 44 and is used to drive the protective cloth take-up roller 44 to rotate, thereby pulling the protective cloth 41 from the protective cloth unwinding roller 43 towards the hot press head 6 and winding up the used protective cloth 41.

[0032] Before processing, the isolation cloth 41 on the release roller 43 is stretched and laid onto the hot press head 6 and the isolation cloth take-up roller 44. During processing, the hot press lifting module 3 drives the hot press head 6 to descend, and the hot press head 6 heat-presses the product to complete the processing. During the descent of the hot press head 6, the isolation cloth 41 is pushed down, so that the hot press head 6 does not directly contact the product, thus protecting both the product and the hot press head 6. After the hot press head 6 completes one hot press processing, the isolation cloth take-up roller 44 is driven to rotate by the isolation cloth take-up motor 45. The isolation cloth take-up roller 44 pulls the isolation cloth 41, removes the used isolation cloth 41 from the hot press head 6, and lays a new isolation cloth 41 on the hot press head 6 for the next hot press processing.

[0033] In other embodiments, the isolation cloth winding motor 45 can be controlled to work after the hot press head 6 has completed multiple hot presses, replacing the isolation cloth 41 on the hot press head 6.

[0034] To ensure the stable laying of the isolation cloth 41, two guide slots 46 are provided on the isolation cloth mounting frame 42, which are symmetrically distributed on both sides of the hot press head 6. After the isolation cloth 41 comes out from the isolation cloth unwinding roller 43, it passes through the two guide slots 46 in sequence and is then fixed on the isolation cloth take-up roller 44.

[0035] In addition, the isolation cloth mounting frame 42 is also equipped with multiple tensioning guide wheels 47. The isolation cloth 41 is laid on each tensioning guide wheel 47 in sequence. The tensioning guide wheels 47 are used to tighten the isolation cloth 41 to ensure that the isolation cloth 41 can be laid flat on the hot press head 6.

[0036] like Figure 5As shown, the CCD positioning mechanism 5 includes a camera mounting bracket 51, which is fixedly connected to the hot-pressing transverse slider 21. A prism mounting bracket 52 and a hot-pressing positioning camera 53 are mounted on the camera mounting bracket 51. A reflector 54 is mounted on the prism mounting bracket 52, located directly below the hot-pressing positioning camera 53. The reflector 54 is tilted at a 45° angle on the prism mounting bracket 52 to acquire an image of the product below the hot-pressing head 6 and reflect the image to the hot-pressing positioning camera 53, thereby achieving precise alignment. During operation, the reflector 54 acquires an image of the product below the hot-pressing head 6 in real time, enabling the hot-pressing positioning camera 53 to capture a clear image of the product; this determines the location on the product requiring hot pressing. Then, through the cooperation of the hot-pressing transverse module 2 and the hot-pressing lifting module 3, the hot-pressing head 6 can accurately press onto the pressing position on the product, ensuring the accuracy of the hot-pressing process.

[0037] In other embodiments, there may be multiple reflectors 54, or they may be set at other tilt angles, as long as the reflector 54 below the hot press positioning camera 53 can obtain a clear product image below the hot press head 6.

[0038] Working principle: Before processing, one end of the isolation cloth 41 on the isolation cloth unwinding roller 43 is pulled out and passed through the tension guide wheel 47 and guide groove 46 in sequence, and laid flat and covered on the lower end face of the hot press head 6, and the end of the isolation cloth 41 is fixed on the isolation cloth take-up roller 44.

[0039] During processing, the feeding mechanism of the automatic hot press equipment transports the product to be processed to a predetermined position on the hot press support 1. Then, the hot press positioning camera 53 acquires an image of the product directly below the hot press head 6 through the reflector 54, identifying and determining the precise hot press position on the product. Next, the hot press transverse motor 22 drives the hot press transverse slider 21 to move laterally, precisely moving the hot press head 6 above the product's hot press position. Then, the hot press lifting motor 31 drives the hot press head 6 downwards. During this process, the heating block 9 maintains the hot press head 6 at its operating temperature, and the hot press head 6 contacts the product through the isolation cloth 41 on its lower end face, maintaining pressure for a period of time (e.g., 5 seconds). During this process, the pressure sensor 7 monitors and provides feedback on the pressing force in real time, achieving controlled hot press processing.

[0040] After the preset time is reached, the hot press head 6 is driven to rise by the hot press lifting module 3 and detach from the product. Then, the hot press horizontal moving module 2 usually moves the hot press head 6 back to the initial position.

[0041] After completing one hot pressing process, the isolation cloth winding motor 45 operates to pull away the used isolation cloth 41 on the hot pressing head 6 and lay a new isolation cloth 41 on the hot pressing head 6 to prepare for the next hot pressing.

[0042] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
