Description

Technical Field

[0001] This utility model relates to the technical field of roller shearing tension adaptive adjustment cutting machine, specifically, to a roller shearing tension adaptive adjustment cutting machine for flexible PCB board processing. Background Technology

[0002] The flexible PCB board processing roller shear with adaptive tension adjustment is a device used to cut flexible printed circuit boards (FPCs). It can automatically adjust the tension according to the material characteristics to ensure the accuracy and quality of the cutting.

[0003] The flexible PCB board processing roller shearing tension adaptive adjustment cutting machine mainly consists of a feeding mechanism, a tension adjustment mechanism, and a roller shearing mechanism. The feeding mechanism transports the rolled flexible PCB board material to the cutting area. The tension adjustment mechanism automatically adjusts according to the tension of the material to maintain a suitable tension. The roller shearing mechanism cuts the material with rotating blades to achieve the cutting requirements of fixed length or fixed size.

[0004] Traditional flexible PCB board processing roller shearing machines with adaptive tension adjustment rely on an adaptive adjustment device that uses a tension sensor to monitor the material's tension in real time and automatically adjusts it according to preset parameters. This ensures that the flexible PCB board maintains constant tension during the cutting process, preventing wrinkles, stretching, and other phenomena, thus guaranteeing cutting accuracy. The entire device is precisely installed on the shearing machine bracket using auxiliary tools. This precise installation method requires professional personnel to use tools for disassembly and reassembly during subsequent replacements, making the replacement operation time-consuming and labor-intensive, and not conducive to rapid replacement. Utility Model Content

[0005] The purpose of this utility model is to provide a roller shear tension adaptive adjustment cutting machine for flexible PCB board processing, which solves the problem that in the existing roller shear tension adaptive adjustment cutting machine for flexible PCB board processing, the replacement steps are inconvenient, and require certain technical and operational requirements, making it highly professional and not conducive to convenient replacement.

[0011] As a preferred embodiment of the above technical solution, the positioning assembly includes insert plates inserted into both ends of the pressure plate, and a spring is fixedly connected to one end of the insert plate inserted into the pressure plate, and the end of the spring away from the insert plate is fixedly connected to the pressure plate.

[0012] As a preferred embodiment of the above technical solution, the insert plate has two sets of chamfers at the end away from the spring, and the chamfer angle at the lower end of the insert plate is greater than the chamfer angle at the upper end.

[0013] The above technical solution involves chamfering at both ends of the insert plate to facilitate the shearing frame and push block pressing the insert plate during subsequent installation and disassembly.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a flexible PCB board processing roller shearing machine with adaptive tension adjustment, including a shearing frame 1, a tension adaptive adjuster 11 inserted into the inner side of the upper end of the shearing frame 1, a limiting component 2 provided at the upper end of the tension adaptive adjuster 11, and the limiting component 2 including a connecting plate 21 fixedly connected to the upper end of the tension adaptive adjuster 11, a pressure plate 22 attached to the upper side of the connecting plate 21, and pin components 3 provided inside both ends of the connecting plate 21, and locking components 4 provided inside both ends of the pressure plate 22, and a pressing component 5 provided at the end of the locking component 4 away from the pressure plate 22. By cooperating with the limiting component 2 and the pin components 3, when the tension adaptive adjuster 11 is replaced, there is no need for cumbersome replacement requirements, and inexperienced employees can operate it themselves, reducing the replacement standard.

[0021] like Figure 3 As shown, a positioning plate 23 is inserted into the inner side of the middle of the pressure plate 22, and the side of the positioning plate 23 away from the pressure plate 22 is fixedly connected to the shearing frame 1. The positioning plate 23 is used to position and restrict the insertion of the connecting plate 21 and the pressure plate 22.

[0022] like Figure 4 As shown, the pin assembly 3 includes a fixing plate 31 fixedly connected to the inner sides of both ends of the connecting plate 21, and a pin 32 fixedly connected to the middle of the fixing plate 31. The lower end of the pin 32 passes through the connecting plate 21 and is inserted into the shearing frame 1. The connecting plate 21 drives the pin 32 to be inserted into the shearing frame 1 under the support of the fixing plate 31, thereby using the fixing plate 31 and the pin 32 to position and limit both ends of the connecting plate 21.

[0023] like Figure 5 As shown, the locking assembly 4 includes insert plates 41 inserted into both ends of the pressure plate 22. One end of the insert plate 41 inserted into the pressure plate 22 is fixedly connected to a spring 42. The end of the spring 42 away from the insert plate 41 is fixedly connected to the pressure plate 22. During the insertion of the pressure plate 22, the shearing frame 1 squeezes the insert plates 41 at both ends of the pressure plate 22, thereby squeezing the insert plates 41 into the pressure plate 22 and compressing the spring 42. When the lower side of the pressure plate 22 is in contact with the connecting plate 21, the elastic potential energy of the spring 42 pushes the insert plate 41 out, so that it is inserted into the shearing frame 1 to lock the pressure plate 22.

[0024] like Figure 5 As shown, the insert plate 41 has two sets of chamfers at the end away from the spring 42, and the chamfer angle at the lower end of the insert plate 41 is greater than the chamfer angle at the upper end. The chamfers at both ends of the insert plate 41 facilitate the insertion of the insert plate 41 into the shear frame 1 and make it press against the shear frame 1. The chamfer at the upper end of the insert plate 41 facilitates the subsequent pressing against it by the push block 51.

[0025] like Figure 5 As shown, the pressing component 5 includes a push block 51 disposed at the end of the insert plate 41 away from the spring 42, and a rubber pad 52 is fixedly connected to the upper end of the push block 51. The lower end of the rubber pad 52 is fixedly connected to the shearing frame 1. Pressing the rubber pads 52 at both ends causes the rubber pads 52 to push the push block 51 down. After the push block 51 moves down, the chamfer at the lower end squeezes the insert plate 41.

[0026] like Figure 5 As shown, the lower end of the push block 51 has an arc-shaped chamfer, and the lower side of the push block 51 is fitted to the upper end of the insert plate 41. By having a chamfer at the lower end of the push block 51, it is easy to squeeze the insert plate 41, thereby pushing the insert plate 41 out of the shearing frame 1.

[0027] Working principle: When replacing the tension adaptive regulator 11, first press the rubber pads 52 at both ends simultaneously, so that the rubber pads 52 push the push block 51 down. After the push block 51 moves down, it uses the chamfer at the lower end to squeeze the insert plate 41. After the insert plate 41 is squeezed, it moves and inserts into the pressure plate 22 to compress the spring 42. When the insert plate 41 is squeezed out of the shear frame 1, the pressure plate 22 can be pulled to pull it out of the shear frame 1. Then, pull the connecting plate 21 to drive the tension adaptive regulator 11 to be pulled out of the shear frame 1 with the assistance of the positioning plate 23. At this time, the removal is completed, and the pressed rubber pads 52 are released. Then, the replaced tension adaptive regulator 11 is inserted into the shear frame 1 through the connecting plate 21 with the assistance of the positioning plate 23. The connecting plate 21 is inserted on the lower side. Once a certain depth is reached, the connecting plate 21 drives the insertion rod 32 to be inserted into the shearing frame 1 under the support of the fixing plate 31. The fixing plate 31 and the insertion rod 32 are used to position and restrict both ends of the connecting plate 21. After insertion, the pressure plate 22 is inserted into the shearing frame 1 with the assistance of the positioning plate 23. During the insertion of the pressure plate 22, the shearing frame 1 squeezes the insertion plates 41 at both ends of the pressure plate 22, so that the insertion plates 41 are squeezed into the pressure plate 22 and the spring 42 is compressed. When the lower side of the pressure plate 22 is in contact with the connecting plate 21, the elastic potential energy of the spring 42 pushes the insertion plate 41 to pop out and insert it into the shearing frame 1 to lock the pressure plate 22, so that the pressure plate 22 can restrict the connecting plate 21 and the tension adaptive adjuster 11.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
