Description

Technical Field

[0001] The present invention relates to the technical field of measuring equipment, and in particular to a dimension measuring device for copper plate and strip processing. Background Art

[0002] Freshly produced copper strip is typically wound into coils in long lengths. It is then cut to specific specifications based on the customer's specifications. In many industries, the dimensions and performance of copper strip must meet specific standards and certification requirements. Accurate measurement is crucial to ensuring these requirements. By measuring the length, width, and thickness of the copper strip, we ensure that its dimensions meet design specifications, thus avoiding assembly issues or performance degradation caused by dimensional deviations. For example, slight variations in width and thickness can affect the product's electrical performance and mechanical strength.

[0003] Currently, dimensional measurement equipment is widely used to measure the length, width, and thickness of copper strips. However, these measurements require the strip to be fixed to prevent movement during measurement, which can affect measurement accuracy. This fixing mechanism can hinder measurement continuity, requiring the strip to be readjusted and refixed before continuing. This cumbersome operation prevents continuous, automated length, width, and thickness measurement, leading to low measurement efficiency. Summary of the Invention

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The copper strip can be rotated and adjusted in position by a rotary clamping mechanism.

The telescopic contact plate can maintain close contact with the copper strip, and the reflector can reflect the laser back to the laser measuring instrument. The stepper motor can drive the wheel to rotate the laser measuring instrument to adjust the direction of the laser measuring instrument, thereby realizing continuous and automatic measurement of the width, length and thickness of the copper strip. There is no need to manually adjust the position of the copper strip, nor to manually repeatedly fix the copper strip, which reduces manual operation steps and greatly improves measurement efficiency.

[0015] 2. The clamp can firmly clamp the copper strip to prevent the copper strip from being skewed due to centrifugal force when the rotary clamping mechanism drives the copper strip to rotate, thereby effectively avoiding the measurement accuracy being affected by the skew of the copper strip.

[0016] 3. The straightening mechanism can straighten the bent copper strip, thereby effectively avoiding the influence of the bending of the copper strip on the measurement accuracy.

[0017] 4. The positioning mechanism can be used to position the rotating seat to prevent the rotating seat from excessively rotating due to inertia, thereby preventing the copper strip from excessively rotating and ensuring that the copper strip rotates accurately by 90 degrees, which helps maintain operational accuracy and stability, thereby improving the measurement accuracy of the copper strip.

[0018] 5. The arc groove and the positioning block can be used to position the wheel, ensuring that the wheel drives the laser measuring instrument to rotate 90 degrees accurately in both directions, so as to avoid the wheel driving the laser measuring instrument to rotate excessively and affect the measurement accuracy, which helps to maintain the operation accuracy and stability.

DETAILED DESCRIPTION

[0030] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

A spring 94 is sleeved on the connecting rod 93, and the two ends of the spring 94 are respectively connected to the slotted slide 92 and the guide block 91. The left side of the slotted slide 92 is connected to a long contact plate 95 for contacting the copper strip, and the left side of the guide block 91 is connected to a short contact plate 96 for contacting the copper strip. The short contact plate 96 is located on the lower side of the slotted slide 92, and the right front side of the long contact plate 95 is connected to a reflector 10 facing the laser measuring instrument 7. The reflector 10 has the same thickness as the short contact plate 96. A contact sensor 11 is embedded in the short contact plate 96, and an opening 111 is opened on the base 1 for the movement of the telescopic contact plate 9.

[0032] See also Figure 2 The rotary clamping mechanism includes an electric push rod 31 installed on the top of the L-shaped fixed plate 2. A rotating seat 33 is rotatably provided on the top of the base 1 and is located directly below the electric push rod 31. A driving motor 34 is installed on the base 1. The output shaft of the driving motor 34 is connected to the bottom of the rotating seat 33 to drive the rotating seat 33 to rotate. A clamping block 32 for clamping the copper plate strip is connected to the top of the rotating seat 33 and the telescopic rod of the electric push rod 31. The upper clamping block 32 is rotatably connected to the telescopic rod of the electric push rod 31. A rubber block 35 is connected to the clamping part of the clamping block 32. The rubber block 35 can not only increase the friction between the clamping block 32 and the copper plate strip to clamp the copper plate strip more firmly, but also can buffer and protect the copper plate strip to avoid the copper plate strip being directly damaged by the hard clamping of the clamping block 32.

[0033] First, pull the long contact plate 95 to the left. The long contact plate 95 drives the slotted slide 92 to the left, compressing spring 1 94. Then, the copper strip is placed on the clamping block 32 of the rotating seat 33. Then, the electric push rod 31 is controlled to drive its upper clamping block 32 downward, clamping the copper strip through the upper and lower clamping blocks 32. Then, the long contact plate 95 is released. Under the reset action of spring 1 94, the slotted slide 92 drives the long contact plate 95 to the right and tightly contacts the copper strip. Then, the electric slide rail 4 is controlled to drive the mounting plate 5 to the left, thereby driving the rotating wheel 6, laser measuring instrument 7, stepper motor 8, guide block 91 and short contact plate 96 to move to the left. The leftward movement of the guide block 91 causes spring 1 94 to continue to reset. The short contact plate 96 moves to the left and contacts the copper strip, and drives the contact sensor 11 to the left and contacts the copper strip. When contact sensor 11 detects contact with the copper strip, it sends a signal to a controller (not shown; the controller is conventional and will not be described here). Upon receiving the signal, the controller controls motorized slide 4 to close. This control then activates laser measuring instrument 7, which emits a laser beam onto reflector 10. Reflector 10 reflects the laser beam back to laser measuring instrument 7. By measuring the time it takes for the laser beam to be reflected by reflector 10, laser measuring instrument 7 calculates the distance between itself and reflector 10, and thus the width of the copper strip.

[0034] After the copper strip's width is measured, the electric slide 4 is first controlled to drive the mounting plate 5 to the right, thereby driving the runner 6, laser measuring instrument 7, stepper motor 8, guide block 91, and short contact plate 96 to the right to clear the copper strip and avoid obstructing subsequent copper strip rotation. Since the long contact plate 95 is now held against the copper strip, it and the slotted slide 92 cannot move rightward, causing the guide block 91 to move rightward and further compress spring 1 94. The drive motor 34 is then controlled to drive the rotating seat 33 to rotate the clamping block 32 thereon 90 degrees, thereby rotating the copper strip 90 degrees. As the copper strip rotates, the long contact plate 95 pushes the slotted slide 92 to the left, further compressing spring 1 94. Spring 1 94 ensures that the long contact plate 95 always maintains contact with the copper strip. The motorized slide 4 then controls the mounting plate 5 to move leftward, causing the laser measuring instrument 7, guide block 91, short contact plate 96, and contact sensor 11 to move leftward. Spring 1 94 resets but remains compressed. When contact sensor 11 detects contact with the copper strip, it sends a signal to the controller. The controller then controls the motorized slide 4 to close, subsequently controlling the laser measuring instrument 7 to operate, thereby calculating the length of the copper strip.

[0035] After the copper strip length is measured, the electric slide 4 is first controlled to move the mounting plate 5 rightward, thereby moving the laser measuring instrument 7, guide block 91, and short contact plate 96 rightward to clear the copper strip and avoid obstructing the subsequent rotation of the guide block 91 and short contact plate 96. Next, the stepper motor 8 is controlled to drive the wheel 6 to rotate 90 degrees, thereby rotating the laser measuring instrument 7 and the entire telescopic contact plate 9 90 degrees. The laser measuring instrument 7, guide block 91, short contact plate 96, and contact sensor 11 are then rotated to the bottom of the copper strip, and the long contact plate 95 is rotated to the top of the copper strip. Simultaneously, the electric slide 4 is controlled to move the mounting plate 5 leftward, causing the laser measuring instrument 7, guide block 91, short contact plate 96, and contact sensor 11 to move leftward, bringing the short contact plate 96 and contact sensor 11 into contact with the bottom of the copper strip. When the contact sensor 11 detects contact with the bottom of the copper strip, it sends a signal to the controller, which then controls the electric slide 4 to close. At this point, the long contact plate 95 has rotated to a horizontal position above the copper strip. Gravity and the return action of spring 1 94 cause the long contact plate 95 to move downward and contact the top of the copper strip. The laser measuring instrument 7 is then controlled to operate, thereby calculating the thickness of the copper strip.

[0036] In this way, the device can continuously and automatically measure the width, length, and thickness of a copper strip, eliminating the need for manual adjustment of the strip's position or repeated manual fixation. This reduces manual operation steps and significantly improves measurement efficiency. After the copper strip is measured, the electric push rod 31 is controlled to move its upper clamping block 32 upward to release the copper strip, and then the copper strip is removed from the clamping block 32 on the rotating base 33. The stepper motor 8 is then controlled to drive the rotating wheel 6 to rotate 90 degrees, thereby causing the laser measuring instrument 7 and the entire telescopic contact plate 9 to rotate 90 degrees and reset. The next round of copper strip measurement can then be performed.

[0037] See also Figure 6-Figure 7 A clamp for clamping the copper plate strip is provided on the upper part of the rotating seat 33, and the clamp includes a connecting ring 12 connected to the upper part of the rotating seat 33. Slide grooves are provided on the front and rear sides of the rotating seat 33, and slide rods 13 are slidably provided in the two slide grooves. The height of the slide rod 13 is lower than the height of the guide block 91 and the long contact plate 95. Springs 2 15 are connected to the left and right sides of the connecting ring 12, and clamping blocks 14 for clamping the copper plate strip are connected to the two springs 2 15. The two clamping blocks 14 are respectively connected to the two slide rods 13.

[0038] Spring 2 15 enables the clamping block 14 to securely clamp the copper strip, preventing it from skewing due to centrifugal force when the rotary clamping mechanism drives the copper strip, thereby effectively avoiding the impact of copper strip skew on measurement accuracy. Because the height of the slide bar 13 is lower than that of the guide block 91 and the long contact plate 95, the slide bar 13 will not collide with the guide block 91 and the long contact plate 95 when rotating synchronously with the rotating base 33. Because the laser measuring instrument 7 has already driven the guide block 91 to the right to avoid the copper strip before the rotating base 33 drives the copper strip and the entire fixture to rotate, the clamping block 14 will not collide with the guide block 91 and the short contact plate 96 when rotating synchronously with the rotating base 33.

[0039] See also Figure 1 and Figure 8 A straightening mechanism for straightening the copper strip is provided on the right rear side of the top of the base 1. The straightening mechanism includes a mounting seat 16 installed on the right rear side of the top of the base 1. A fixed roller 17 is rotatably connected to the upper part of the mounting seat 16 from front to back. A lifting plate 18 is slidably provided on the upper part of the mounting seat 16 above the fixed roller 17. The lifting plate 18 is in the shape of an inverted U. A movable roller 19 is rotatably connected to the inverted U-shaped lifting plate 18 from front to back. A screw 20 is threadedly connected to the top of the mounting seat 16, and the screw 20 is rotatably connected to the top of the lifting plate 18.

[0040] The copper strip is inserted from back to front between the movable roller 19 and the fixed roller 17, and then pulled forward from between the movable roller 19 and the fixed roller 17. The cooperation between the movable roller 19 and the fixed roller 17 can straighten the bent copper strip, effectively preventing the bending of the copper strip from affecting measurement accuracy. Rotating the screw 20 drives the lifting plate 18 to drive the movable roller 19 up and down, thereby adjusting the gap between the movable roller 19 and the fixed roller 17 to accommodate copper strips of different thicknesses.

[0041] See also Figure 6 and Figure 9 A positioning mechanism for positioning the rotating seat 33 is provided at the top of the base 1. The positioning mechanism includes a guide sleeve 23 installed on the top of the base 1. The guide sleeve 23 is located on the right side of the rotating seat 33. A sliding rod 24 is slidingly provided in the guide sleeve 23. A clamping block 25 is connected to the sliding rod 24. The clamping block 25 is in the shape of a T. A spring three 26 is sleeved on the sliding rod 24. The two ends of the spring three 26 are respectively in contact with the clamping block 25 and the guide sleeve 23. A circular ring 21 is connected to the lower part of the rotating seat 33. Protrusions 22 are connected to the outer wall of the circular ring 21 at intervals along the circumferential direction. The clamping block 25 is inserted between two adjacent protrusions 22 to position the rotating seat 33.

[0042] The rotation of the rotating seat 33 drives the protrusion 22 to rotate through the ring 21, and the rotation of the protrusion 22 pushes the block 25 to move to the right, compressing the spring three 26. When the protrusion 22 passes the block 25, under the reset action of the spring three 26, the block 25 is pushed to be inserted between two adjacent protrusions 22. In this way, the rotating seat 33 can be positioned to prevent the rotating seat 33 from rotating excessively due to inertia, thereby preventing the copper strip from rotating excessively, ensuring that the copper strip rotates accurately by 90 degrees, and helping to maintain operational accuracy and stability to improve the measurement accuracy of the copper strip.

[0043] See also Figure 10 An arc-shaped groove 27 is opened on the rear side of the bottom of the rotating wheel 6, and a positioning block 28 located in the arc-shaped groove 27 is connected to the inner wall of the rear side of the U-shaped plate of the mounting plate 5. Through the cooperation of the arc-shaped groove 27 and the positioning block 28, the rotating wheel 6 can be positioned to ensure that the rotating wheel 6 drives the laser measuring instrument 7 to accurately rotate 90 degrees forward and backward, so as to avoid the rotating wheel 6 driving the laser measuring instrument 7 to rotate excessively and affect the measurement accuracy, which helps to maintain the operation accuracy and stability.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications, improvements, and substitutions without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
