Description

Technical Field

[0001] This invention relates to the field of brass sheet and strip production technology, specifically to a dimensional inspection device and method for brass sheet and strip production and processing. Background Technology

[0002] Brass sheet and strip, as an important product in the copper processing field, is an alloy material with copper and zinc as the main components. It is made into sheet or strip through rolling process. With its excellent processability, conductivity and corrosion resistance, it occupies an irreplaceable position in industrial manufacturing. In the future, with the rapid development of new energy, electronic information and other industries, brass sheet and strip will evolve towards high precision, environmental protection and functionalization.

[0003] A Chinese patent with publication number CN114087994A discloses a dimensional inspection device for brass sheet and strip production and processing, comprising: a mounting base plate, on the top of which a trajectory correction mechanism, a laser measurement mechanism, and a data processing mechanism are fixedly installed respectively. The laser measurement mechanism includes a rectangular groove A, with two trajectory rods fixedly inserted between the two sides of the inner wall of the rectangular groove A, and two movable plates movably sleeved between the outer walls of the two trajectory rods. By setting up the laser measurement mechanism, the device adds the ability to position the product to be measured, and replaces the existing method of manually measuring product dimensions. It calculates the dimension value by utilizing the laser emission end and the time when the final light is blocked, avoiding the problem of excessive offset angle caused by various external factors when the existing measuring tools are in contact with the product surface. This effectively speeds up the generation rate of dimension values ​​and prevents the product from being unable to match the specified collection structure during the subsequent winding process.

[0004] As mentioned above, this patent provides a dimensional inspection device for brass strip production and processing, which can effectively accelerate the generation rate of dimensional values ​​and prevent the product from failing to match the specified collection structure during the winding process. However, during inspection, it is not possible to perform multi-directional adjustment scanning as needed, so the position of the brass strip needs to be repeatedly adjusted, which affects the accuracy of the inspection and may also cause damage to the surface of the brass strip. The overall inspection effect needs to be improved. Therefore, in order to address the above problems, a dimensional inspection device and inspection method for brass strip production and processing is proposed. Summary of the Invention

[0040] 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 scope of protection of the present invention.

[0041] Example 1

[0042] Please see Figures 1-11As shown, a size detection device and method for brass sheet and strip production and processing includes a transmission box 1, a support base 2, and an adjustment assembly; the adjustment assembly includes a transverse reciprocating lead screw 3 and a longitudinal reciprocating lead screw 4, the surface of the transverse reciprocating lead screw 3 is threaded with a size detector 5, and the surface of the longitudinal reciprocating lead screw 4 is threaded with a placement base 6.

[0043] A motor housing 7 is fixedly connected to one side of the transmission box 1. An electric motor 8 is fixedly connected inside the motor housing 7. The output shaft of the electric motor 8 is fixedly connected to a transmission shaft 9 via a coupling. An electric telescopic rod 10 is fixedly connected to one end of the transmission shaft 9. A transmission lever 11 is fixedly connected to one end of the electric telescopic rod 10. A support shaft 12 is rotatably connected to the inner wall of the transmission box 1 away from the electric motor 8. A drive pulley 13 is fixedly connected to the surface of the support shaft 12. A transmission groove 14 adapted to the transmission lever 11 is provided at one end of the support shaft 12. The transverse reciprocating lead screw 3... One end of the drive shaft 9 is fixedly connected to a driven pulley 15. The surface of the drive pulley 13 is connected to the surface of the driven pulley 15 via a belt. The surface of the drive shaft 9 near the electric telescopic rod 10 is fixedly connected to a drive bevel gear 16. The surface of the longitudinal reciprocating screw 4 is fixedly connected to a driven bevel gear 17. The rear surface of the transmission box 1 is slidably connected to an adjusting pinion 18. One end of the adjusting pinion 18 is fixedly connected to a drive bevel gear 19. A strong spring 20 is sleeved on the surface of the adjusting pinion 18. A sliding washer 21 is fixedly connected to the end of the strong spring 20 away from the drive bevel gear 19.

[0044] During operation, the dimension detector 5 is used to detect the length of the brass strip, the placement seat 6 is used to place the brass strip, and the motor housing 7 supports and protects the motor 8. When the motor 8 is working, it drives the transmission shaft 9 to start rotating through the output shaft. After the transmission shaft 9 rotates, it drives the active bevel gear 16 and the electric telescopic rod 10 to start rotating. When it is necessary to drive the active pulley 13 to rotate, the electric telescopic rod 10 works to drive the transmission clamp 11 to engage in the transmission groove 14 at one end of the support shaft 12. At the same time, when the transmission clamp 11 is not in the transmission groove 14, the active pulley 13 will not rotate with the electric telescopic rod 10. When the active pulley 13 rotates, it drives the driven pulley 15 to rotate through the belt, which in turn drives the transverse reciprocating screw 3 to rotate, which in turn drives the dimension detector 5 to move laterally reciprocating along the transverse reciprocating screw 3. Additionally, a strong spring 20 is fitted onto the surface of the adjusting shaft 18. The strong spring 20 drives the adjusting shaft 18 to move away from the rear of the transmission box 1, causing the transmission bevel gear 19 at one end of the adjusting shaft 18 to mesh with the driving bevel gear 16. This allows the driving bevel gear 16 to drive the transmission bevel gear 19 to rotate, which in turn drives the driven bevel gear 17 to rotate. When the driven bevel gear 17 rotates, it drives the longitudinal reciprocating screw 4 to rotate, which in turn drives the support seat 2 to move longitudinally back and forth. Through the structural design of the adjusting assembly, the dimensional detector 5 can move laterally and the placement seat 6 can move longitudinally. This solves the problem of repeatedly adjusting the position of the brass strip, which affects the detection accuracy and may damage the surface of the brass strip, thus improving detection efficiency. Furthermore, the structural design of the gear rotation combined with the electric telescopic rod 10 and the adjusting shaft 18 enables free control of lateral and longitudinal movement. Only one power supply device is needed for bidirectional control, solving the problem of requiring two power supply devices for bidirectional sliding and improving adaptability.

[0045] Furthermore, the bottom of the support base 2 is fixedly connected to the rear side of the top of the transmission box 1, the two ends of the transverse reciprocating lead screw 3 are rotatably connected to the two sides of the support base 2, the two ends of the longitudinal reciprocating lead screw 4 are rotatably connected to the inner wall of the transmission box 1, and the surface of the placement seat 6 is slidably connected to the top of the transmission box 1. A shaft support frame 22 is fixedly connected to the bottom of the inner wall of the transmission box 1. Two shaft support frames 22 are provided, and the two shaft support frames 22 are symmetrically arranged on both sides of the inner wall of the transmission box 1. The two shaft support frames 22 are rotatably connected to the surfaces of the transmission shaft 9 and the support rotating shaft 12, respectively.

[0046] During operation, the transmission box 1 supports the support seat 2, the support seat 2 provides rotational support for the transverse reciprocating lead screw 3, and the transmission box 1 provides sliding support for the placement seat 6. In addition, two shaft support frames 22 are provided. The bottom of the inner wall of the transmission box 1 supports the rotation of the two shaft support frames 22. The transmission shaft 9 and the support rotating shaft 12 rotate on the two shaft support frames 22 respectively, and the shaft support frames 22 support the rotation of the transmission shaft 9 and the support rotating shaft 12 respectively.

[0047] Furthermore, one end of the adjusting pin shaft 18 passes through the transmission box 1 and extends to the rear side of the transmission box 1. A positioning block 23 is fixedly connected to the end of the adjusting pin shaft 18 located at the rear side of the transmission box 1. A rotating bracket 24 is fixedly connected to the surface of the transmission box 1 and on both sides of the positioning block 23. A stop bar 25 is rotatably connected to the surface of the rotating bracket 24.

[0048] During operation, when the support base 2 is not required to move longitudinally, the positioning block 23 is pulled to move the adjusting shaft 18 toward the rear of the transmission box 1, thereby disengaging the transmission bevel gear 19 from the driving bevel gear 16 and the driven bevel gear 17. Then, the stop lever 25 is rotated to lock the stop lever 25 at the positioning block 23, thus fixing the adjusting shaft 18 and preventing the driving bevel gear 16 from driving the transmission bevel gear 19 to rotate, thereby preventing the longitudinal reciprocating screw 4 from rotating.

[0049] Furthermore, an isolation plate 26 is fixedly connected to the inner wall of the transmission box 1, the surface of the longitudinal reciprocating screw 4 is rotatably connected to the surface of the isolation plate 26, and the two sides of the placement seat 6 are slidably connected to limit shafts 27, the two ends of the limit shafts 27 being fixedly connected to the surface of the isolation plate 26 and the inner wall of the transmission box 1, respectively.

[0050] During operation, an isolation plate 26 is set up to protect one side of the transmission box 1 and support the rotation of the longitudinal reciprocating screw 4. The limiting shaft 27 is fixed on the inner wall of the isolation plate 26 and the transmission box 1, while the placement seat 6 can slide on the limiting shaft 27, thereby completing the limiting shaft 27 to support and limit the placement seat 6.

[0051] Furthermore, one side of the size detector 5 is slidably connected to one side of the top of the support base 2, and a U-shaped support rod 28 is fixedly connected to the top of the support base 2. The top of the surface of the size detector 5 is slidably connected to the surface of the U-shaped support rod 28, and a sliding wheel 29 is provided on one side of the bottom of the size detector 5. The surface of the sliding wheel 29 is tumblingly connected to the surface of the support base 2.

[0052] During operation, one side of the size detector 5 is locked onto the top of the support base 2, and it can also slide on the support base 2. At the same time, a U-shaped support rod 28 is provided, and the size detector 5 can slide back and forth along the U-shaped support rod 28. The support base 2 and the U-shaped support rod 28 limit the size detector 5. The sliding wheel 29 can roll on the support base 2, reducing the friction between the support base 2 and the size detector 5, making the lateral reciprocating movement of the size detector 5 smoother.

[0053] Furthermore, sliding rails 30 are fixedly connected to both sides of the top of the transmission box 1, and sliding guide rails 31 adapted to the sliding rails 30 are provided on both sides of the placement seat 6. Sliding platforms 32 are slidably connected to both sides of the top of the placement seat 6. An adjusting slide rod 33 is slidably connected to one side of the top of the sliding platform 32. A pressing block 34 is fixedly connected to the bottom end of the adjusting slide rod 33. A tension spring 35 is sleeved on the surface of the adjusting slide rod 33, and the bottom end of the tension spring 35 is fixedly connected to the top of the sliding platform 32. A bidirectional lead screw 36 is threadedly connected to the surface of the sliding platform 32. One end of the bidirectional lead screw 36 passes through the placement seat 6 and extends to one side of the placement seat 6. The number of sliding platforms 32 is set to four, and the four sliding platforms 32 are symmetrically arranged in pairs on both sides of the placement seat 6.

[0054] During operation, the sliding rail 30 supports and limits the placement seat 6, while the placement seat 6 is engaged with the sliding rails 31 on both sides of the sliding rail 30, so that the sliding rail 30 and the sliding rails 31 cooperate to limit each other. The sliding table 32 can slide on the top of the placement seat 6, and the adjusting rod 33 slides on the sliding table 32. The tension spring 35 pulls the adjusting rod 33 down, which in turn drives the pressing block 34 to press down, and then presses it onto the brass strip. In addition, a bidirectional screw 36 is provided. The rotation of the bidirectional screw 36 drives the two sliding tables 32 connected to it to move away from or closer to each other, realizing the function of adjusting the clamping width. It can clamp the four corners of brass strips of different widths, solving the problem that the brass strip is prone to curling when clamped alone, and improving the flatness during inspection.

[0055] Furthermore, an electrical control box 37 is fixedly connected to the bottom of the transmission box 1, a support pad 38 is fixedly connected to the bottom of the electrical control box 37, a rotating frame 39 is rotatably connected to the surface of the electrical control box 37, an operating table 40 is fixedly connected to one side of the rotating frame 39, and a controller 41 is fixedly connected to the top of the operating table 40.

[0056] During operation, the electrical control box 37 supports the transmission box 1, and the electrical control box 37 contains a power supply. The support pad 38 supports the electrical control box 37. The rotating frame 39 can rotate on the surface of the electrical control box 37 and also supports the operating table 40. The controller 41 is set on the operating table 40 and controls the entire detection operation.

[0057] Furthermore, a method for dimensional inspection in the production and processing of brass sheet and strip includes the following steps:

[0058] S1: Place the brass strip on the placement seat 6, and clamp its four corners by adjusting the four symmetrically arranged sliding clamps 32. Rotate the double-acting screw 36 to adjust the clamping width, and the tension spring 35 drives the pressing block 34 to press down, ensuring that the strip is flat and free of curling.

[0059] S2: The controller 41 starts the motor 8, drives the transmission shaft 9 and the electric telescopic rod 10. The electric telescopic rod 10 extends, so that the transmission clamp 11 is inserted into the transmission groove 14 of the support shaft 12, and drives the drive pulley 13 to drive the transverse reciprocating screw 3 through the belt.

[0060] S3: The transverse reciprocating screw 3 rotates, driving the dimension detector 5 to move laterally along the support 2. It slides stably through the sliding wheel 29 and the U-shaped support rod 28 to scan the width of the brass strip.

[0061] S4: The electric telescopic rod 10 retracts, the transmission lever 11 disengages from the transmission slot 14, the adjusting shaft 18 resets under the action of the strong spring 20, the transmission bevel gear 19 meshes with the driving bevel gear 16 and the driven bevel gear 17, driving the longitudinal reciprocating screw 4 to rotate, and the longitudinal reciprocating screw 4 drives the placement seat 6 to move longitudinally along the sliding track 30, cooperating with the transverse detection of the entire length of the cover plate.
