[0025] Example

[0026] To address the problems of high manpower consumption and low efficiency in existing technologies that rely on manual conductivity testing of individual copper foils using multimeters, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses an integrated die-cutting and conductivity testing device, including a rotary die-cutting machine 10, a conductivity testing mechanism 30, and a laser engraving marking mechanism 40. The base of the rotary die-cutting machine 10 is provided with a testing platform 20 on its discharge side. The testing platform 20 is provided with a feeding groove 21 for the material to be fed. The copper foil products (located on the material strip) die-cut by the rotary die-cutting machine 10 will enter the feeding groove 21.

[0027] The conductivity testing mechanism 30 includes a tester 31, a positive electrode 32, a negative electrode 33, an inverted L-shaped bracket 34, and a lifting drive unit 35. The tester 31 is mounted on the base of the rotary die-cutting machine 10. The inverted L-shaped bracket 34 is mounted on the testing platform 20 with its horizontal portion facing the feed chute 21. The lifting drive unit 35 is positioned above the horizontal portion of the inverted L-shaped bracket 34. The positive electrode 32 and the negative electrode 33 are respectively connected to the lifting drive unit 35 below the inverted L-shaped bracket 34 and can enter the feed chute 21 under the drive of the lifting drive unit 35. When the copper foil product enters the feed chute 21, the lifting drive unit 35 will drive the positive electrode 32 and the negative electrode 33 to descend and contact the copper foil product. At the same time, the tester 31 will test the conductivity of the copper foil product and send the relevant information to the control system (known technology) used to control the entire device.

[0028] The laser marking mechanism 40 includes a mounting bracket 41 and a laser marking head 42. The mounting bracket 41 is located on the lateral part of the inverted L-shaped bracket 34 away from the circular die-cutting machine 10. The laser marking head 42 is mounted on the mounting bracket 41 and corresponds to the feed chute 21. Based on the above test results, if the conductivity of the copper foil product is unqualified, the laser marking head 42 will laser mark the unqualified product. Conversely, if the conductivity of the copper foil product is qualified, the laser marking head 42 will not operate.

[0029] In order to avoid wear on the side walls of the feed chute 21 during the movement of the feed chute, this application provides MC cast nylon 22 on the side walls of the feed chute 21. This material has good strength and wear resistance and a long service life.

[0030] This application may select the lifting drive unit 35 as one of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. In specific implementation, if there are other types of lifting drive units 35 that can perform the functions of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, those skilled in the art may choose accordingly.

[0031] In a preferred embodiment, the lifting drive unit 35 of this application is connected to a lifting plate 36 below the lateral portion of the inverted L-shaped bracket 34. The positive electrode 32 and the negative electrode 33 are located on both sides of the bottom of the lifting plate 36 in the material feeding direction. The inverted L-shaped bracket 34 is provided with first guide holes 341 around its perimeter. The lifting plate 36 is connected with first guide posts passing through the first guide holes 341 around its perimeter. The top of the first guide post 361 is provided with a first limiting nut 3611. When the lifting drive unit 35 drives the lifting plate 36 to descend, the positive electrode 32 and the negative electrode 33 located below the lifting plate 36 can be smoothly lifted and lowered through the cooperation of the first guide post 361 and the first guide hole 341, which has strong practicality.

[0032] In addition, to prevent the positive electrode 32 and the negative electrode 33 from rigidly contacting the copper foil product, this application provides elastic modules 37 on both sides of the bottom of the lifting plate 36. The positive electrode 32 and the negative electrode 33 are respectively set at the bottom of the two elastic modules 37. The elastic module 37 includes a support plate 371. Two second guide holes 362 are opened on both sides of the lifting plate 36. Two second guide posts 3711 are connected to the upper sides of the support plate 371 and pass through the two second guide holes 362. A second limit nut 37111 is provided at the top of the second guide post 3711. A spring 372 is provided between the limit nut and the lifting plate 36. When the lifting drive unit 35 drives the lifting plate 36 to descend, the two support plates 371 can achieve elastic contact with the copper foil product under the action of the spring 372 and the second limit nut 37111, thus avoiding the situation of crushing the copper foil product.

[0033] In one specific embodiment, the mounting bracket 41 of this application is provided with a manual fine-tuning module 43, and the laser engraving head 42 is mounted on the manual fine-tuning module 43. Before the laser engraving head 42 starts working, the operator can operate the manual fine-tuning module 43 to drive the laser engraving head to rise and fall, thereby ensuring that the laser engraving head 42 is in a better laser engraving position.
