Description

Technical Field

[0001] This invention relates to the field of copper strip testing technology for electronic components, and particularly to a device for testing the flatness of copper strips on the surface of electronic components. Background Technology

[0002] Electronic components are the building blocks of electronic parts and small machines and instruments. They are typically composed of several parts and are interchangeable among similar products. They often refer to certain parts in industries such as electrical appliances, radio, and instrumentation, and are a general term for electronic devices such as capacitors, transistors, hairsprings, and mainsprings. Copper bars are a common metallic material made of pure copper, commonly used in copper sculpture, tableware processing, and electrical and electronic components. Copper bars have excellent electrical and thermal conductivity, corrosion resistance, and machinability, thus they are widely used in industrial fields.

[0003] In the circuit board manufacturing process, copper pouring mainly refers to laying copper foil layers on the surface of the circuit board. This provides the circuit board with a more robust, oxidation-resistant, and highly conductive surface, allowing for a stronger connection between electronic components and the circuit board, thereby improving the reliability of the circuit board. At the same time, copper pouring can also increase the conductivity of the circuit board, enabling signals to be transmitted more quickly and stably. On the other hand, in the use of circuit boards, the role of copper pouring mainly involves electrical performance. Circuit boards usually need to carry various electrical signals and currents, so they need to have certain conductivity and anti-interference capabilities. Copper pouring can improve the capacitance of the circuit board and the transmission quality of electrical signals, while also reducing electromagnetic interference and sensitivity to external electromagnetic interference.

[0004] During the production process of copper strips on the surface of electronic components, in order to improve the inspection efficiency, most factories use manual visual inspection and strong light irradiation to check the flatness of the produced copper strips. However, manual visual inspection and strong light irradiation are only convenient for detecting whether there are bumps on the surface of steel strips. During the production process, copper strips may be tilted, and visual inspection and strong light irradiation are prone to errors, resulting in insufficient flatness of the copper strips. This affects the appearance quality and conductivity of the copper strips on the surface of electronic components. Therefore, there is a need to provide a flatness inspection device for copper strips on the surface of electronic components to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a device for detecting the flatness of copper strips on the surface of electronic components, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an electronic component surface copper strip flatness testing device, comprising a testing box and a door panel, wherein the door panel is hinged to the testing box on the side near the testing box, an electric push rod is provided on the top of the inner surface of the testing box, a push plate is fixedly connected to the bottom of the electric push rod, a fixed cylinder is fixedly connected to the upper surface of the push plate, and a testing component for testing the surface flatness of the copper strip is provided inside the fixed cylinder and at the bottom of the push plate;

[0007] The detection assembly includes a movable push rod slidably connected inside a fixed cylinder. A baffle is fixedly connected to the top of the movable push rod. Detection slots are provided on both sides of the fixed cylinder. A connecting base plate is fixedly connected to the end of the movable push rod away from the detection slot. Detection indicator rods are fixedly connected to both sides of the movable push rod. The end of the detection indicator rod away from the movable push rod is slidably connected inside the detection slot. A compression spring is fixedly connected to the surface of the movable push rod. The two ends of the compression spring are fixedly connected to a push plate and a connecting base plate, respectively. Flexible sensors are provided at the four corners of the surface of the connecting base plate near the push plate. Inductive touch pads are provided at the four corners of the side of the connecting base plate away from the movable push rod. A millimeter scale is provided on the outer surface of the fixed cylinder.

[0008] As a further improvement to the above solution, the inside of the testing box has two sliding rods. The two ends of the two sliding rods are respectively fixedly connected to a first fixing plate and a second fixing plate. The inside of the first fixing plate and the second fixing plate, which are close to each other, is slidably connected to an installation rod. The ends of the two installation rods, which are close to each other, are respectively fixedly connected to a first limiting plate and a second limiting plate. The inside of the testing box is provided with a fixing component for clamping copper strips. The first fixing plate, the second fixing plate, and the inside of the testing box are provided with a transmission component.

[0009] As a further improvement to the above solution, the fixing component includes a drive motor fixedly connected inside the detection box, a bidirectional screw rotatably connected inside the detection box, the end of the bidirectional screw near the drive motor being connected to the drive motor, two sliding sleeves being threaded onto the surface of the bidirectional screw, a connecting rod being fixedly connected to the bottom of each of the two sliding sleeves, and the ends of the two connecting rods away from the sliding sleeves being fixedly connected to the upper surface of the sliding rod.

[0010] As a further improvement to the above solution, the transmission assembly includes a fixed rack fixedly connected inside the detection box. Limiting screws are rotatably connected inside both the first and second fixed plates. The ends of the two limiting screws away from the first and second fixed plates pass through the interior of the slide rod and are fixedly connected to gears. Both gears mesh with the fixed rack. Limiting sleeves are threaded onto the surfaces of the limiting screws inside the first and second fixed plates. The sides of the two limiting sleeves that are close to each other are fixedly connected to one end of the mounting rod.

[0011] As a further improvement to the above solution, limit sliders are fixedly connected to both sides of the push plate, and limit grooves are opened on both sides inside the detection box. The end of the limit slider away from the push plate is slidably connected to the inside of the limit groove.

[0012] As a further improvement to the above solution, a limiting opening is provided on the side surface of the first fixing plate and the second fixing plate that are close to each other, and the end of the mounting rod away from the limiting screw sleeve is slidably connected to the inside of the limiting opening.

[0013] As a further improvement to the above solution, a sliding opening is provided on the side of the detection box away from the door panel, and the end of the slide rod away from the gear is slidably connected inside the sliding opening.

[0014] As a further improvement to the above scheme, the limiting ports on the surfaces of the first fixing plate and the second fixing plate are distributed in a crisscross pattern, and the positions of the limiting ports on the surfaces of the first fixing plate and the second fixing plate are on the same horizontal line.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By using multiple flexible sensors at the same level, and by recording the different timing of the contact between the flexible sensors and the sensing pads with the copper strip, and combining this with the sliding position information of the detection indicator rod and the connecting base plate inside the fixed cylinder, the sliding scale of the connecting base plate and the detection indicator rod inside each fixed cylinder can be viewed by observing the sliding position of the detection indicator rod. The difference between the scales can clearly detect the flatness of the copper strip, and the combination of the two can further improve the accuracy of copper strip flatness detection.

[0017] 2. The copper strip placed inside the detection box can be fixed on both sides by activating the fixing component. During the fixing process, the transmission component transmits power to limit the copper strip from the other two ends, keeping the copper strip in the center of the first fixing plate and the second fixing plate. This ensures that the center of the copper strip and the push plate are on the same vertical line, which makes it easier for the flexible sensors on the vertically sliding connecting base plate to fit against the surface of the copper strip. This facilitates the detection of the flatness and tilt of the copper strip surface and avoids the copper strip being misaligned, which could lead to incomplete contact between the sensing pad at the bottom of the flexible sensor and the copper strip.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0035] Please see Figures 1 to 9 The present invention provides an embodiment of an electronic component surface copper strip flatness testing device, including a testing box 1 and a door panel 18. The door panel 18 is hinged to the testing box 1 on the side close to the testing box 1. An electric push rod 2 is provided on the top of the inner surface of the testing box 1. A push plate 3 is fixedly connected to the bottom of the electric push rod 2. A fixed cylinder 4 is fixedly connected to the upper surface of the push plate 3. A testing component for testing the surface flatness of the copper strip is provided inside the fixed cylinder 4 and at the bottom of the push plate 3.

[0036] The detection assembly includes a movable push rod 501 slidably connected inside the fixed cylinder 4. A baffle 503 is fixedly connected to the top of the movable push rod 501. Detection slots 504 are provided on both sides of the fixed cylinder 4. A connecting base plate 502 is fixedly connected to the end of the movable push rod 501 away from the detection slots 504. Detection indicator rods 505 are fixedly connected to both sides of the movable push rod 501. The end of the detection indicator rod 505 away from the movable push rod 501 is slidably connected inside the detection slots 504. A compression spring 506 is fixedly connected to the surface of the movable push rod 501. The two ends of the compression spring 506 are fixedly connected to the push plate 3 and the connecting base plate 502, respectively. Flexible sensors 507 are provided at the four corners of the surface of the connecting base plate 502 near the push plate 3. Inductive pads 508 are provided at the four corners of the side of the connecting base plate 502 away from the movable push rod 501. A millimeter scale 509 is provided on the outer surface of the fixed cylinder 4.

[0037] Specifically, the electric push rod 2 causes the sensing pads 508 at the four corners of the bottom of the detection component to contact the surface of the copper strip first. At the same height and under the maximum tension of the compression spring 506, the multiple sensing pads 508 are at the same level. When the surface of the copper strip is tilted or uneven as the electric push rod 2 slides down, the sensing pad 508 that first contacts the copper strip will send a signal to the corresponding flexible sensor 507. As the push rod continues to slide down, the remaining sensing pads 508 successively contact the copper strip, and so on. The signal is sent to the corresponding flexible sensor 507 to record the sensing information. After multiple sensing pads 508 have touched the copper strip, the sensing pad 508 that makes the first contact will compress the compression spring 506 as it continues to slide down. This causes the connection between the base plate 502 and the detection indicator rod 505 to be connected. Through the millimeter scale 509 on the surface of the multiple fixed cylinders 4, the position of the detection indicator rod 505 on the millimeter scale 509 can be quickly displayed, thereby detecting whether there is any tilting or unevenness on the surface of the copper strip.

[0038] Reference Figure 2 , Figure 7 and Figure 8 As shown, there are two sliding rods 6 inside the testing box 1. The two ends of the two sliding rods 6 are respectively fixedly connected to a first fixing plate 7 and a second fixing plate 8. The sides of the first fixing plate 7 and the second fixing plate 8 that are close to each other are slidably connected to mounting rods 9. The ends of the two mounting rods 9 that are close to each other are respectively fixedly connected to a first limiting plate 10 and a second limiting plate 11. The testing box 1 is equipped with a fixing component for clamping copper strips. The first fixing plate 7, the second fixing plate 8 and the testing box 1 are equipped with a transmission component.

[0039] The fixing assembly includes a drive motor 120 fixedly connected inside the detection box 1. A bidirectional screw 121 is rotatably connected inside the detection box 1. The end of the bidirectional screw 121 near the drive motor 120 is connected to the drive motor 120. Two sliding sleeves 122 are threaded onto the surface of the bidirectional screw 121. A connecting rod 123 is fixedly connected to the bottom of each of the two sliding sleeves 122. The ends of the two connecting rods 123 away from the sliding sleeves 122 are fixedly connected to the upper surface of the slide rod 6.

[0040] The side of the test box 1 away from the door panel 18 has a sliding opening 16, and the end of the slide rod 6 away from the gear 132 is slidably connected to the inside of the sliding opening 16;

[0041] Specifically, the fixing components can act as a drive, allowing the first fixing plate 7 and the second fixing plate 8 to slide in opposite directions inside the detection box 1, thereby clamping the copper strip inside the detection box 1 and preventing the copper strip from moving and affecting the detection results.

[0042] The transmission assembly includes a fixed rack 130 fixedly connected inside the detection box 1. Limiting screws 131 are rotatably connected inside the first fixing plate 7 and the second fixing plate 8. The ends of the two limiting screws 131 away from the first fixing plate 7 and the second fixing plate 8 are inserted through the slide rod 6 and fixedly connected to gears 132. Both gears 132 are meshed with the fixed rack 130. The surfaces of the limiting screws 131 inside the first fixing plate 7 and the second fixing plate 8 are threaded with limiting sleeves 133. The sides of the two limiting sleeves 133 that are close to each other are fixedly connected to one end of the mounting rod 9.

[0043] Limiting openings 17 are provided on the side surfaces of fixing plate 7 and fixing plate 8 that are close to each other. The end of the mounting rod 9 away from the limiting screw sleeve 133 is slidably connected to the inside of the limiting opening 17.

[0044] The limiting ports 17 on the surfaces of the first fixing plate 7 and the second fixing plate 8 are distributed in a crisscross pattern, and the positions of the limiting ports 17 on the surfaces of the first fixing plate 7 and the second fixing plate 8 are on the same horizontal line.

[0045] Specifically, the transmission component can transmit the force generated by the fixing component. Under the limitation of the fixed rack 130, the transmitted force can realize the rotation of the limiting screw 131 and the gear 132. Thus, under the action of the opposite rotational force and the thread, the limiting screw sleeve 133 and the mounting rod 9 can be kept to slide horizontally inside the first fixing plate 7 and the second fixing plate 8. This allows the first limiting plate 10 and the second limiting plate 11 to slide in different directions, limiting the other two sides of the copper strip that are not clamped. This moves the copper strip that is not in the center inside the detection box 1 to the center position, so that the center of the copper strip is kept on the same vertical line as the center of the push plate 3. This makes it easier to detect the flatness of the copper strip surface and avoids the copper strip misalignment affecting the detection effect of the copper strip surface flatness.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, limit sliders 14 are fixedly connected to both sides of the push plate 3, and limit grooves 15 are opened on both sides inside the detection box 1. The end of the limit slider 14 away from the push plate 3 is slidably connected to the inside of the limit groove 15.

[0047] Specifically, the limiting slider 14 and the limiting groove 15 are designed to limit the up and down movement of the push plate 3, thus preventing the push plate 3 from wobbling during its movement.

[0048] Based on the above preferred embodiments, the working principle of the present invention is as follows:

[0049] In the initial state, the sides of the first fixing plate 7 and the second fixing plate 8 that are far apart are in contact with the inside of the detection box 1. The distance between the first fixing plate 7 and the second fixing plate 8 is the maximum distance, and the distance between the first limiting plate 10 and the second limiting plate 11 is also the maximum distance. The multiple compression springs 506 are not compressed.

[0050] During work:

[0051] The steps before preparing to test the flatness of the copper strip are as follows:

[0052] When the staff places the copper strip to be tested inside the testing box 1, the staff then starts the drive motor 120. After the drive motor 120 starts, it drives the bidirectional screw 121 to rotate. Under the action of the bidirectional thread and the sliding limit of the sliding rod 6 by the sliding port 16, the bidirectional screw 121 can push the two sliding sleeves 122 to slide in opposite directions on the bidirectional screw 121. Thus, the two connecting rods 123 and the sliding rod 6 can slide in opposite directions with the two sliding sleeves 122 respectively. Thus, the sliding of the two sliding rods 6 in opposite directions can drive the first fixing plate 7 and the second fixing plate 8 to slide in opposite directions. This can achieve the function of fixing the copper strip placed between the first fixing plate 7 and the second fixing plate 8 inside the testing box 1, and prevent the copper strip from moving when testing the surface of the copper strip, so as to avoid affecting the detection effect of the flatness of the copper strip.

[0053] During the clamping of the copper strip inside the testing box 1, the sliding rods 6 fixed at the bottom slide synchronously when the two sliding sleeves 122 slide in opposite directions. The opposite sliding of the two sliding rods 6 causes the limiting screws 131, which are rotatably connected inside the two sliding rods 6, to move. Since the limiting screws 131 and gears 132 are fixed, and gears 132 mesh with a fixed rack 130, the position of the fixed rack 130 remains fixed. Therefore, the movement of the sliding rods 6 causes the limiting screws 131 inside the sliding rods 6 to rotate and mesh with the fixed rack 130 under the action of gears 132 meshing with the fixed rack 130. The rotation of gears 132 simultaneously drives the limiting screws 131 to rotate. Because the two sliding rods 6 move in different directions, they cause the two limiting screws 131 and gears 132 to slide in opposite directions, thus causing the two limiting screws... The rod 131 rotates in opposite directions on the surface of the fixed rack 130, while the limiting screws 131 inside the first fixed plate 7 and the second fixed plate 8 rotate in opposite directions under the action of the threads and the limiting port 17. This allows the limiting screw sleeve 133 on the surface of the limiting screw 131 to slide horizontally inside the first fixed plate 7 and the second fixed plate 8. Under the connection of the mounting rod 9, the first limiting plate 10 and the second limiting plate 11 slide in opposite directions, allowing the first limiting plate 10 and the second limiting plate 11 to limit the copper strip from the other two sides. This keeps the placed copper strip in the center position of the first fixed plate 7 and the second fixed plate 8, so that the center of the copper strip and the push plate 3 are on the same vertical line. This makes it easier to detect the flatness of the copper strip surface and avoids the copper strip being misaligned, which would prevent detection and affect the detection effect of the copper strip flatness.

[0054] The steps for checking the flatness of copper strips are as follows:

[0055] After the copper strip is clamped and positioned, the electric push rod 2 is activated to push the push plate 3, the fixing cylinder 4, and the detection components downwards. Since the detection components on both sides of the push plate 3 are separately installed, and the compression spring 506 is in its maximum released state, multiple sensor pads 508 are at the same level. When the copper strip surface is uneven, the sliding of the push plate 3 pushes the connecting base plate 502 and the flexible sensor 507 downwards, causing one of the sensor pads 508 at the same level to contact the copper strip surface first. The first sensor pad 508 to touch the copper strip will send a signal to the corresponding flexible sensor 507 to record its sensing information. As the electric push rod 2 continuously pushes the push plate 3, the connecting base plate 502, and the flexible sensor 507 downwards, the remaining sensor pads 508 will successively touch the copper strip and send signals to the corresponding flexible sensors 507 to record their sensing information. After multiple sensor pads 508 have touched the copper strip, the first sensor pad 508 to make contact will compress the compression spring 506 as it continues to slide downwards, causing the connecting base plate 502 to be compressed. The plate 502 and the detection indicator rod 505 slide inside the fixed cylinder 4, while the detection indicator rod 505 slides inside the detection through groove 504. Due to the millimeter scale 509 set on the outside of the fixed cylinder 4, the contact time between each flexible sensor 507 and the copper strip will be different when the copper strip surface is uneven. Therefore, the sliding positions of the connecting base plate 502 and the detection indicator rod 505 in each fixed cylinder 4 will also be different. According to the different positions of the detection indicator rod 505 sliding on the millimeter scale 509, it will show whether there is a tilt or unevenness on the copper strip surface. At the same time, the information recorded by the flexible sensor 507 and the sensing pad 508 is different. Through the time difference of the information recorded by the sequential sensing, the flatness of the copper strip surface can be clearly reflected, and the tilt of the copper strip surface can be detected. Through the display of the millimeter scale 509 and the detection between the flexible sensor 507 and the sensing pad 508, the flatness of the copper strip surface can be detected, and the accuracy of the flatness detection of the copper strip surface can be further improved.
