[0002] In the bonding process between carbon fiber sheets and steel plates, a fixing device is needed to position and clamp the specimens to ensure bonding quality and curing effect. Currently, most fixing devices on the market are fixed structures that cannot be adjusted according to the size of the carbon fiber sheet or steel plate specimens. They can only accommodate specimens of a single specification, limiting their applicability and failing to meet the diverse processing needs of today. Furthermore, existing fixing devices cannot individually adjust the pressure and position of each clamping point when clamping specimens of different sizes. This easily leads to uneven distribution of clamping points, excessive or insufficient local pressure, affecting the bonding strength between the carbon fiber sheet and steel plate and the uniformity of the adhesive layer. Additionally, repeated disassembly and adjustment of the clamps to accommodate different specimens is cumbersome and severely reduces work efficiency. Utility Model Content

[0019] The present application provides a description of a carbon fiber plate bonding and fixing device.

[0020] Please see Figure 1 The diagram below shows the structure of the present invention. The carbon fiber plate bonding and fixing device includes a workbench 1 and multiple side-by-side supports 2. Symmetrical guide rails 3 are provided on both sides of the workbench 1. The supports 2 include two parallel support rods 201 and a horizontal beam 202 disposed between the two support rods 201. The bottoms of the two support rods 201 are slidably connected to the two guide rails 3 respectively. Multiple retractable clamping components are slidably connected to the beam 202. The bottom of the clamping components is provided with suction cups 4.

[0021] In use, the carbon fiber plate coated with adhesive and the steel plate specimen are neatly stacked and placed on the surface of workbench 1. Adjust the position of the support bracket 2 according to the specimen size, moving it to the weakest areas such as the edges and center of the specimen. The operator slides the clamping assembly to ensure that the clamping points are evenly distributed on the specimen surface after the clamping assembly is pressed down; adjust the length of the clamping assembly so that the suction cup 4 slowly approaches and adheres to the surface of the carbon fiber plate until the suction cup 4 applies clamping force to the specimen, and the adhesive fully fills the gap between the carbon fiber plate and the steel plate under the action of the suction cup 4. After the adhesive has cured, adjust the length of the clamping assembly to detach the suction cup 4 from the specimen surface, and move the support bracket 2 to both sides of workbench 1. Remove the bonded specimen from workbench 1.

[0022] This device, through the sliding engagement of the bracket 2 and the guide rail 3, can be adapted to carbon fiber plates and steel plate specimens of different sizes, making it widely applicable and highly versatile. The clamping components slide with the crossbeam 202, allowing for flexible adjustment of the clamping point position to ensure uniform clamping. Multiple clamping components exert multi-point, uniform clamping force on the specimen, avoiding the problem of uneven pressure in traditional clamps and improving bonding quality and efficiency.

[0023] In this embodiment, the crossbeam 202 is provided with a strip groove 203 along its length. The clamping assembly includes an adjusting bolt 5 and a locking nut 6. The adjusting bolt 5 is slidably connected to the strip groove 203, and the locking nut 6 is threadedly engaged with the adjusting bolt 5. Specifically, in use, after the bracket 2 slides to the preset position, the operator moves each adjusting bolt 5 along the strip groove 203 to the corresponding clamping point, and tightens the locking nut 6 on each adjusting bolt 5 with a wrench to lock the position of the adjusting bolt 5 on the crossbeam 202. Then, the head of the adjusting bolt 5 is turned to drive the suction cup 4 to slowly move downward toward the specimen. After the suction cup 4 adheres to the specimen and applies a certain pressure, the locking nut 6 is finely adjusted again to ensure that the longitudinal position of the bolt does not loosen.

[0024] Furthermore, a connecting shaft 7 is coaxially connected to the end of the adjusting bolt 5, and the bottom of the connecting shaft 7 is movably connected to the top of the suction cup 4; an annular step is provided between the adjusting bolt 5 and the connecting shaft 7, and a buffer spring (not shown in the figure) abuts against the annular step and the top of the suction cup 4. The annular step limits the buffer spring to prevent the spring from falling off; the buffer spring is used to avoid excessive pressure from damaging the carbon fiber plate and to ensure that the pressure on the adhesive layer is uniform and stable until the adhesive is cured.

[0025] Specifically, a slider 9 is connected to the bottom of the support rod 201, and the slider 9 is slidably connected to the guide rail 3; a linear displacement component 8 is provided on the guide rail 3, and the moving end of the linear displacement component 8 is connected to the slider 9. Under the action of the linear displacement component 8, the bracket 2 slides along the guide rail 3 to a preset position. Compared with manually pushing the bracket 2 to slide, this ensures that the bonding quality remains stable in different batches of operations, reduces the movement error of the bracket 2, and improves the positioning accuracy and efficiency of the bracket 2.

[0026] In this embodiment, the linear displacement assembly 8 includes a drive motor and a driving wheel and a driven wheel disposed at both ends of the guide rail 3. The driving wheel and the driven wheel are connected by a synchronous belt drive. The output shaft of the drive motor is connected to the rotating shaft of the driving wheel, and the synchronous belt is connected to the slider 9. In other embodiments, the linear displacement assembly 8 can be a lead screw motor, an electric actuator, or a cylinder, etc.

[0027] Specifically, the suction cup 4 has a silicone protective layer on its surface, and its air path is connected to an external vacuum pump. The silicone protective layer can conform to the tiny bumps and depressions on the surface of the substrate and prevent the suction cup 4 from scratching the substrate surface. The external vacuum pump extracts air between the suction cup 4 and the substrate through the air path, creating a negative pressure inside the suction cup 4, which improves the adhesion strength. At the same time, the pressure of each clamping point of the suction cup 4 can be adjusted individually, ensuring the uniformity of pressure on the specimen.

[0028] Furthermore, a removable heating chamber (not shown in the figure) is provided on the surface of the workbench 1. Multiple heating elements are installed on the inner wall of the heating chamber, and these elements are connected to a temperature controller. The heating chamber can cover the workbench 1 and the specimen to be bonded, forming a surrounding heating environment. Traditional heating chambers require transferring the specimen to the chamber, which can easily lead to misalignment of the adhesive layer. The movable and removable heating chamber in this embodiment solves the above-mentioned problems of traditional heating chambers, while also avoiding uneven curing of the adhesive layer caused by localized heating in traditional heating chambers, thus improving the bonding quality and efficiency of the carbon fiber board and the steel plate.

[0029] Furthermore, a circulating fan is installed on the top of the heating chamber, and a viewing window is opened on the side of the heating chamber.

[0030] Furthermore, the surface of the workbench 1 is provided with a crosshair reference line, and a positioning stop (not shown in the figure) is detachably connected to the surface of the workbench 1. In this embodiment, the workbench 1 is a horizontal steel plate platform, and the positioning stop is magnetically attracted to the surface of the workbench 1. The crosshair reference line provides a reference, and in conjunction with the magnetic positioning stop, it can quickly align the specimen, reduce positioning errors, and improve the efficiency of specimen placement and positioning. The positioning stop is detachable and magnetically fixed, and its position can be adjusted according to the specimen size, making it widely applicable.

[0031] The working process of this utility model is as follows: During use, according to the size of the specimen to be bonded, the positioning strip is adsorbed onto the corresponding position of the cross baseline on the workbench 1. The carbon fiber plate and steel plate specimens coated with adhesive are neatly stacked and placed along the positioning strip on the surface of the workbench 1, ensuring that the edge of the specimen is aligned with the baseline. The linear displacement component 8 is activated, driving the support 2 to slide along the guide rail 3. The position of the support 2 is determined according to the size of the specimen, moving the support 2 to the weak areas such as the edge and middle of the specimen. The operator slides the adjusting bolt 5 along the strip groove 203 on the crossbeam 202, ensuring that the pressing points after pressing are evenly distributed on the surface of the specimen, and tightens the locking nut 6 to lock the lateral position. Then, the head of the adjusting bolt 5 is turned, causing the suction cup 4 to move down and adhere to the surface of the specimen. At the same time, the external vacuum pump is activated, causing the suction cup 4 to adsorb the specimen under negative pressure until a suitable clamping force is applied to the specimen. Cover the work area of ​​workbench 1 with the heating chamber, connect the temperature controller, set the curing temperature according to the curing requirements of the adhesive, and start the heating element. During this period, the temperature controller maintains a stable temperature inside the chamber in real time until the adhesive layer is completely cured. After the adhesive has cured, adjust the length of the clamping component to detach the suction cup 4 from the surface of the specimen, and move the bracket 2 to both sides of workbench 1. Remove the bonded specimen from workbench 1 to complete one bonding operation.
