Description

Technical Field

[0001] This utility model relates to the field of adhesive cutting machine technology, specifically a vertical hydraulic adhesive cutting machine for flexible copper-clad laminates. Background Technology

[0002] Flexible copper-clad laminates (CCLs), as the core material for flexible circuit boards, are widely used in precision electronic terminal products such as smartphones, laptops, new energy vehicle electronics, and wearable devices due to their lightweight, thinness, bendability, and resistance to high and low temperatures. As electronic devices rapidly evolve towards miniaturization, high density, and flexibility, the market is placing increasingly stringent demands on the production precision and stability of flexible CCLs.

[0003] Adhesive layer cutting is a crucial pre-process in the production of flexible copper-clad laminates. Its cutting accuracy directly affects the subsequent lamination quality of the metal foil, adhesive layer, and substrate film. If the adhesive layer has dimensional deviations, rough edges, or tilted positioning, it can lead to defects such as interlayer delamination, voids, and dimensional deviations in the laminated product, seriously affecting the performance of the final electronic components. Although ordinary vertical hydraulic adhesive cutting machines have achieved mechanized cutting, they lack a precise adhesive layer thickness detection mechanism. The adhesive layer thickness must be measured manually in advance, and the hydraulic cutting parameters must be manually adjusted. This is not only cumbersome to operate, but also prone to over-cutting, under-cutting, or adhesive layer stretching deformation due to inaccurate parameter adaptation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vertical hydraulic adhesive cutting machine for flexible copper-clad laminates, which has the advantage of processing according to the thickness of the copper board and solves the problem of poor cutting quality caused by inaccurate parameter matching.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A vertical hydraulic adhesive cutting machine for flexible copper-clad laminates includes a base, a bracket fixedly connected to the base, a hydraulic cylinder mounted on the bracket, and a blade fixedly connected to the free end of the hydraulic cylinder. The bracket is equipped with a testing mechanism for detecting the thickness of the copper plate, and the base is equipped with a calibration mechanism for calibrating the position of the copper plate. The testing mechanism includes a load-bearing plate fixedly connected to the bracket, a sliding rod slidably connected to the load-bearing plate, a transmission bar fixedly connected to the bottom end of the sliding rod, a transmission disc fitted onto the sliding rod, a tension spring fixedly connected between the transmission disc and the load-bearing plate, a slider fixedly connected to the transmission disc, and a linear displacement sensor corresponding to the slider fixedly connected to the load-bearing plate. The calibration mechanism includes U-shaped bars slidably connected to both sides of the base, the U-shaped bars being horizontally placed, the two U-shaped bars moving in opposite directions, and push plates fixedly connected to the opposite ends of the two U-shaped bars.

[0006] Preferably, a limit bar is rotatably mounted on the top of the slide bar, and a support platform for raising the limit bar is fixed to the load-bearing plate.

[0007] Preferably, the opposing ends of the two U-shaped bars are fixedly connected to symmetrically distributed racks, a rotating shaft is rotatably installed in the base, a spur gear that meshes with the racks is mounted on the rotating shaft, and an electric telescopic rod is also fixedly installed in the base. The free end of the electric telescopic rod is fixedly connected to a rack that meshes with the spur gear, and the rack is located below the racks.

[0008] Preferably, the signal output terminal of the linear displacement sensor is electrically connected to a controller, and the signal output terminal of the controller is electrically connected to the control terminal of the hydraulic cylinder. The controller is used to receive the copper plate thickness signal detected by the linear displacement sensor and to adjust the cutting pressure and cutting stroke of the hydraulic cylinder.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, including a vertical hydraulic glue-cutting machine for flexible copper-clad laminates.

[0017] Example 1: Combination Figure 1 and Figure 3 As shown, the vertical hydraulic adhesive cutting machine for flexible copper-clad laminates provided by this utility model includes a base 100, a bracket 101 fixedly connected to the base 100, a hydraulic cylinder 102 mounted on the bracket 101, a blade 103 fixedly connected to the free end of the hydraulic cylinder 102, a testing mechanism 200 for detecting the thickness of the copper plate on the bracket 101, and a calibration mechanism 300 for calibrating the copper plate on the base 100. This enables the adhesive cutting machine to simultaneously perform copper plate thickness detection and position calibration functions, solving the problem that traditional adhesive cutting machines require separate thickness measurement and manual calibration, and realizing an integrated preparation process before cutting. The testing mechanism 200 includes a load-bearing plate 201 fixed to a bracket 101. A slide rod 203 is slidably connected to the load-bearing plate 201. A transmission bar 202 is fixed to the bottom end of the slide rod 203. A transmission disc 204 is mounted on the slide rod 203. A tension spring 205 is fixed between the transmission disc 204 and the load-bearing plate 201. A slider 206 is fixed to the transmission disc 204. A linear displacement sensor 207 corresponding to the slider 206 is fixed to the load-bearing plate 201. First, the tension spring 205 pulls the transmission disc 204 downward. Then, the transmission disc 204 drives the slide rod 203 upward. As the slide bar 202 moves downwards, it moves along with the slide bar 203. Subsequently, the slide bar 202 contacts the copper plate, and the slider 206 on the transmission disk 204 also stops moving. The linear displacement sensor 207 detects the position of the slider 206, thereby detecting the thickness of the copper plate. The cutting force can then be adjusted according to the thickness of the copper plate. The thickness signal can be converted into a basis for adjusting the cutting parameters in real time, which solves the problem of inaccurate parameter adaptation when cutting copper plates of different thicknesses, avoids material damage caused by overcutting, undercutting or improper cutting force, and improves the cutting quality. The correction mechanism 300 includes U-shaped bars 301 slidably connected to both sides of the base 100. The U-shaped bars 301 are placed horizontally, and the two U-shaped bars 301 move in opposite directions. Push plates 302 are fixed to the opposite ends of the two U-shaped bars 301. The two U-shaped bars 301 drive the push plates 302 to move towards the middle, which can effectively correct the tilt state when the copper plate is placed and solve the problem of inconsistent cutting dimensions caused by the positioning deviation of the copper plate.

[0018] Specifically, a limiting strip 208 is rotatably mounted on the top of the slide bar 203, and a support platform 209 for lifting the limiting strip 208 is fixed on the load-bearing plate 201. When processing the same batch of copper plates, after measurement is completed, the limiting strip 208 can be pulled up. The limiting strip 208 drives the transmission plate 204 to move, which in turn drives the transmission bar 202 at the end of the slide bar 203 on the transmission plate 204 to move. Then, the limiting strip 208 is rotated so that it rests on the support platform 209, preventing the tension spring 205 from pulling the transmission plate 204 and causing the transmission bar 202 below it to move, thus avoiding obstruction of subsequent copper plates. When processing the same batch of copper plates, the position of the transmission bar 202 can be fixed to prevent the tension spring 205 from continuously driving the transmission bar 202 to move down and obstructing the loading and unloading of subsequent copper plates. This solves the tedious problem of repeatedly adjusting the transmission bar 202 during batch operations, reduces non-processing time, and improves work efficiency.

[0019] The signal output terminal of the linear displacement sensor 207 is electrically connected to a controller, and the signal output terminal of the controller is electrically connected to the control terminal of the hydraulic cylinder 102. The controller is used to receive the copper plate thickness signal detected by the linear displacement sensor 207 and to adjust the cutting pressure and cutting stroke of the hydraulic cylinder 102. The linear displacement sensor 207 converts the detected copper plate thickness into a 4-20mA current signal or a 0-10V voltage signal (analog electrical signal). This signal is transmitted to the signal input terminal of the controller through a shielded wire. The A / D conversion module inside the controller converts the analog electrical signal into a digital quantity and compares it with a preset thickness-parameter database. The database stores the optimal cutting pressure value corresponding to different copper plate thicknesses (e.g., 5MPa for 0.1mm thickness, 15MPa for 3mm thickness). The controller generates corresponding control commands through the arithmetic unit based on the comparison results, and then converts the commands into PWM pulse signals or 4-20mA control signals. After being amplified by the drive circuit, the signals are transmitted to the electro-hydraulic proportional valve (control end) of the hydraulic cylinder 102 through the control wire. After receiving the signal, the proportional valve adjusts the opening of the internal valve core to change the flow rate and pressure of hydraulic oil entering the rodless chamber of the hydraulic cylinder 102, so as to achieve precise control of the cutting pressure of the hydraulic cylinder 102 (adjusted by closed loop feedback from the pressure sensor) and the cutting stroke (calibrated by the built-in displacement sensor of the hydraulic cylinder 102). At the same time, the controller receives the feedback signal from the linear displacement sensor 207 in real time for dynamic correction to ensure that the cutting parameters always match the actual copper plate thickness.

[0020] Furthermore, a handle 210 is fixedly connected to the limit strip 208, and the outer surface of the handle 210 is fitted with an anti-slip sleeve to facilitate the operation of the limit strip 208 by the staff.

[0021] As can be seen from the embodiments, there is no need for manual judgment and adjustment of cutting pressure and stroke, which solves the problems of lag and error in manual adjustment, improves the accuracy and response speed of parameter adjustment, further ensures the cutting accuracy of copper plates of different thicknesses, and reduces the dependence on the operator's experience.

[0022] Example 2: Combination Figure 2 and Figure 4As shown, based on Embodiment 1, two U-shaped bars 301 have symmetrically distributed racks 303 fixedly connected to their opposite ends. A rotating shaft is rotatably mounted inside the base 100, and a spur gear 304 meshing with the racks 303 is mounted on the shaft. An electric telescopic rod 305 is also fixedly installed inside the base 100. A rack 306 meshing with the spur gear 304 is fixedly connected to the free end of the electric telescopic rod 305. The rack 306 is located below the racks 303. When 305 is activated, its free end extends and retracts, causing rack 2 306 to move. Rack 2 306 meshes with spur gear 304, causing it to rotate. The rotation of spur gear 304 causes rack 1 303 on both sides to move relative to each other. Rack 1 303 causes U-shaped bar 301 on it to move. Push plate 302 moves with U-shaped bar 301, which can correct the position of copper plates of different sizes, ensuring the synchronicity and consistency of the movement of push plates 302 on both sides, and avoiding the secondary displacement of copper plates caused by uneven force on one side.

[0023] Furthermore, a buffer pad is fixed to the side of the push plate 302 away from the U-shaped strip 301. The buffer pad is made of silicone, which can effectively alleviate the impact force of hard contact between the push plate 302 and the copper plate during calibration, and prevent the copper plate edge from being deformed, scratched or damaged due to squeezing.

[0024] As can be seen from the above embodiments: the worker first places the flexible copper-clad laminate to be processed on the workbench of the base 100. At this time, the limiting bar 208 of the testing mechanism 200 rests on the support platform 209, causing the transmission bar 202 to be in a raised state. Then, the correction mechanism 300 is activated, and the electric telescopic rod 305 is activated to drive the rack 2 306 to move. The rack 2 306 meshes with the spur gear 304 to drive it to rotate. The spur gear 304 then drives the two symmetrical racks 1 303 to move relative to each other. The rack 1 303 drives the corresponding U-shaped bar 301 to move in the opposite direction to the center. The push plate 302 at the end of the U-shaped bar 301 then moves towards the center and gently clamps the copper plate with the silicone buffer pad to complete the position correction to avoid tilting. After the correction is completed, the worker holds the handle 210 with the anti-slip sleeve and rotates the limiting bar 208 to make it disengage from the support platform 209. Under the tension of the tension spring 205, the transmission plate 204 moves downward and drives the slide bar 203 to move downward. As the slide bar 203 moves downward, the transmission bar 202 at the bottom of the slide bar 203 moves downward until it is in contact with the upper surface of the copper plate. At this time, the slider 206 on the transmission disc 204 stops moving. After the linear displacement sensor 207 detects the position of the slider 206, it transmits the thickness signal to the controller. The controller automatically adjusts the cutting pressure and cutting stroke parameters of the hydraulic cylinder 102 according to the signal. After the parameters are adjusted, the hydraulic cylinder 102 starts, and its free end drives the cutter 103 to move downward and accurately cut the corrected copper plate according to the preset parameters. After the cutting is completed, the hydraulic cylinder 102 drives the cutter 103 to reset, and the electric telescopic rod 305 reverses to drive the push plate 302 and the U-shaped bar 301 back to the initial position. The operator then rotates the limit bar 208 through the handle 210 and places it on the support platform 209 to lift the transmission bar 202. Then, the cut copper plate is removed and the next copper plate to be processed is placed. The above process is repeated for batch processing.
