Description

Technical Field

[0001] This utility model relates to the field of steel plate measurement technology, specifically a steel plate thickness measuring device for copper-clad laminate production. Background Technology

[0002] With the trend towards thinner and lighter copper-clad laminates (CCLs) in the electronics industry, the requirements for thickness uniformity in CCL production are becoming increasingly stringent. In the CCL lamination process, multiple CCLs are often stacked in the order of steel plate / CCL / steel plate... Therefore, in order to improve the thickness uniformity of CCLs in the hot pressing process, it is necessary to monitor the thickness uniformity of the fixture, i.e., the steel plate.

[0003] Existing technologies mostly use micrometers or ultrasonic measuring instruments (accuracy 10μm) to measure manually. The measuring personnel take multiple measurements according to the measurement points. The entire measurement process requires the personnel to squat down and manually carry the steel plates. Manual measurement is inefficient, cannot perform full inspection, and has a large measurement error (measurement accuracy is 10μm). Secondary sampling is required, which may lead to the omission of some defective steel plates.

[0004] Therefore, we propose a steel plate thickness measuring device for copper clad laminate production to solve the problems mentioned above. Utility Model Content

Example

[0027] Please see Figure 1-8 A steel plate thickness measuring device for copper clad laminate production includes a frame 1. Placement trays 9 are provided on both sides of the bottom of the frame 1 (one placement tray 9 can be used to place the steel plate after inspection, and the other placement tray 9 can be used to place the steel plate to be inspected). A support plate 2 is provided on the bottom of the frame 1 near the other side. A cleaning component 5 is provided on one side of the support plate 2. A controller 3 is fixedly installed on the front side of the frame 1 near the middle. A display 4 is provided on the front side of the frame 1 near the middle. A support frame A7 is provided on the other side of the placement tray 9, and a support frame B8 is provided on the other side of the support frame A7. A handling component 6 is provided on the top of the frame 1.

[0028] The handling assembly 6 includes two electric slide rails A69 fixedly installed in the inner cavity of the frame 1 near the middle position, and an electric slider A68 slidably connected in the inner cavity of the adjacent electric slide rails A69. A sliding plate 61 is fixedly installed on the top of the electric sliders A68. A servo motor B62 is fixedly installed on the top of the sliding plate 61 near the other side. A worm gear 63 is fixedly installed on the end of the power output shaft of the servo motor B62. A worm wheel is meshed on the front side of the worm gear 63, and a threaded tube 64 is provided through the top of the worm wheel. The bottom end of the threaded tube 64 passes through the inner cavity of the sliding plate 61. A threaded rod B65 is threaded through the inner cavity of the threaded tube 64. A rectangular plate 66 is fixedly installed on the bottom end of the threaded rod B65. Several suction cups 67 are fixedly installed on the bottom of the rectangular plate 66 (the suction cups 67 are controlled by a vacuum generator and a solenoid valve to open and close).

[0029] Specifically, when handling steel plates, with the cooperation of the handling component 6, the steel plates can be adsorbed by the suction cup 67 and placed on the mounting frame on top of the support frame B8, eliminating the need for manual handling and inspection, and greatly reducing the workload of the staff.

[0030] A round rod 612 is fixedly installed on the top of the rectangular plate 66 near its four sides. A cylinder 611 is provided through the top of the sliding plate 61 near its four sides. The top of the round rod 612 moves through the inner cavity of the adjacent cylinder 611.

[0031] Specifically, the circular rod 612 and the cylindrical tube 611 can limit the movement of the rectangular plate 66.

[0032] A laser 83 is installed on the top of the support frame B8 near the rear side. Two mounting brackets are provided on the top of the support frame B8 near the middle position. A mounting plate is fixedly installed on the top middle position of the support frame B8, and several straight rods are provided through one side of the mounting plate. Several rollers A85 are fixedly sleeved on the outer periphery of each straight rod. Several mounting holes are opened on the top of the mounting brackets near the middle position, and rollers B86 are rotatably connected to the inner cavity of each mounting hole.

An adjustment plate 84 is fixedly installed on the top of adjacent electric sliders C82. An adjustment block 81 is fixedly installed on the top of the support frame B8 near the rear side.

[0033] Specifically, by setting up the electric slide rail C87 and the electric slider C82, the adjusting plate 84 moves towards the steel plate, thereby clamping both sides of the steel plate. Then, it releases the steel plate and moves away from it. At this time, the roller A85 will slowly rotate, driving the steel plate towards the adjusting block 81. When the top of the steel plate reaches the adjusting block 81, the adjusting plate 84 will move towards the steel plate, and the adjusting plate 84 and the adjusting block 81 will clamp the steel plate, thus completing the steel plate positioning. After the steel plate completes the above positioning process, the adjusting plate 84 will release the steel plate and move away from it. At this time, according to actual needs, the laser 83 will engrave a preset number on the surface of the steel plate.

A placement rack 77 is fixedly installed on the top of the support frame A7.

[0035] Specifically, by setting up several laser thickness gauges 76, the thickness of the steel plate can be detected. Multi-point accurate thickness measurement improves the uniformity of the steel plate thickness and can screen out steel plates with good thickness uniformity. In the copper clad laminate lamination process, it can improve the thickness uniformity of the copper clad laminate during the hot pressing process. Moreover, the steel plate thickness results of multi-point thickness measurement are automatically imported into the system and compared with the steel plate thickness specification set for this model of steel plate. If the steel plate thickness exceeds the specification, the display 4 will prompt an alarm, and personnel will reject the steel plate that exceeds the thickness specification. Example

[0036] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 4 , Figure 7 and Figure 8The cleaning component 5 includes a connecting block 51 fixedly installed on one side of the support plate 2 near the front and rear sides, and a support block 52 fixedly installed on the rear connecting block 51. A servo motor A53 is fixedly installed at the bottom of the support block 52, and a threaded rod A54 is fixedly installed at the end of the power output shaft of the servo motor A53. The front end of the threaded rod A54 moves through the inner cavity of the connecting block 51 and is rotatably connected to a component away from the connecting block 51. A threaded sleeve 55 is threadedly connected to the outer periphery of the threaded rod A54 near the front end. One side of the threaded sleeve 55... A connecting block 56 is fixedly installed, and an electric telescopic rod 57 is fixedly installed at the bottom center of the connecting block 56. An n-shaped plate is fixedly installed at the bottom end of the electric telescopic rod 57. A cleaning roller 58 is provided in the inner cavity of the n-shaped plate (the cleaning roller 58 has several dust suction holes). Straight rods (hollow tubes) are fixedly installed on both sides of the cleaning roller 58. The opposite sides of the straight rods movably penetrate the inner cavity sidewall of the n-shaped plate. A drive motor 59 is provided on one side of the n-shaped plate. The power output shaft of the drive motor 59 is fixedly connected to the adjacent straight rod.

[0037] Specifically, when cleaning the top of the steel plate, the cleaning component 5 can be used in conjunction with the cleaning roller 58 to rotate and move backward on the top of the steel plate, thereby cleaning the dust or impurities on the top of the steel plate, improving the adsorption effect of the suction cup 67, and preventing it from falling during hoisting.

[0038] A load-bearing plate 591 is fixedly installed on the top of the drive motor 59, and the other side of the load-bearing plate 591 is fixedly connected to the n-shaped plate. A hose 592 is rotatably connected to the end of the straight rod on the other side. A pump body 593 is fixedly installed on one side of the support plate 2 near the rear side (the air outlet of the pump body 593 is connected to an external ash storage device). The hose 592 is inserted into the pump body 593.

[0039] Specifically, the load-bearing plate 591 can support the drive motor 59, and the hose 592 and pump body 593 can handle the dust.

[0040] A limiting block 551 is fixedly installed on one side of the threaded sleeve 55, and a limiting rod 552 is provided through the front side of the limiting block 551, and the front and rear ends of the limiting rod 552 are fixedly connected to the adjacent connecting block 51 respectively.

[0041] Specifically, by setting the limit block 551 and the limit rod 552, the movement of the threaded sleeve 55 can be limited.

[0042] Working Principle: In use, the electric telescopic rod 57 of this invention is activated by the controller 3 to adjust the cleaning roller 58 to fit against the steel plate. Then, the drive motor 59 and servo motor A53 are activated by the controller 3. The rotation of the power output shaft of the servo motor A53 drives the threaded rod A54, which is fixed to the end of the power output shaft of the servo motor A53, to rotate. This causes the threaded sleeve 55, which is threaded onto the outer circumference of the threaded rod A54, to move backward under the limitation of the limiting block 551 and the limiting rod 552. The rotation of the power output shaft of the drive motor 59 causes the straight rod, which is fixed to the end of the power output shaft of the drive motor 59, to rotate, thereby allowing the cleaning roller 58 to rotate and clean the top of the steel plate. The pump body 593 and the soft... Pipe 592 can clean the dust. After cleaning, the operator can start the servo motor B62 through the controller 3. The rotation of the power output shaft of the servo motor B62 rotates the worm gear 63 fixed at the end of the power output shaft, which in turn rotates the worm wheel meshing with the worm gear 63, thereby rotating the adjacent threaded pipe 64. This causes the threaded rod B65 to push the rectangular plate 66 downward under the limit of several round rods 612, so that the suction cup 67 can be used to adhere and fix the steel plate. Then, the rectangular plate 66 is adjusted upward, and the sliding plate 61 is moved to one side by the electric slider A68 and the electric slide rail A69. After adjusting to the appropriate position, the steel plate is placed on the mounting bracket. The electric slide rail C87 and electric slider C82 are set to move the adjusting plate 84 towards the steel plate, thereby clamping both sides of the steel plate. Then, the steel plate is released and moved away from the steel plate. At this time, the roller A85 will slowly rotate, driving the steel plate towards the adjusting block 81. When the top of the steel plate reaches the adjusting block 81, the adjusting plate 84 will move towards the steel plate. The adjusting plate 84 and the adjusting block 81 clamp the steel plate, thus completing the steel plate positioning. After the steel plate completes the above positioning process, the adjusting plate 84 will release the steel plate and move away from the steel plate. According to actual needs, it is marked by the laser 83. It should be noted that all the information of the steel plate will be displayed on the display 4. At this time, the suction cup 6 7. The steel plate is picked up and placed on top of the placement rack 77 on the support frame A7. The information marked by the identifier 75 is scanned and the model, length and width of the steel plate are displayed on the display 4. The thickness of the steel plate can be detected by setting several laser thickness gauges 76. The multi-point accurate thickness measurement improves the uniformity of the steel plate thickness and can screen out steel plates with good thickness uniformity. In the copper clad laminate lamination process, it can improve the thickness uniformity of the copper clad laminate in the hot pressing process. The thickness results of the steel plate measured by multiple points are automatically imported into the system and compared with the steel plate thickness specification set for this model of steel plate. If the thickness exceeds the steel plate thickness specification, the display 4 will prompt an alarm and personnel will reject the steel plate that exceeds the thickness specification.

[0043] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
