Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-6As shown, a RF connector spring cutting device comprises a workbench 1, on which an automatic feeding mechanism 2 and a conveying and cutting mechanism 3 are provided, the automatic feeding mechanism 2 is used to convey a spring strip 13 to the conveying and cutting mechanism 3; the conveying and cutting mechanism 3 comprises a conveying mechanism 4 and a cutting mechanism 5, the cutting mechanism 5 is arranged between two conveying mechanisms 4, the conveying mechanism 4 is used to convey the spring strip 13, and the cutting mechanism 5 is used to cut the spring strip 13; the conveying and cutting mechanism 3 is installed on a cutting table 6, a receiving box 7 is provided at the bottom of the cutting table 6, the receiving box 7 is installed on the workbench 1, and an opening corresponding to the cutting mechanism 5 is provided at the top thereof, so that the cut spring strip falls into the receiving box 7 conveniently, the receiving box 7 is used to receive the spring strip cut by the cutting mechanism 5, and a drawer 8 is provided on the receiving box 7, so that the cut spring strip can be taken out conveniently. The workbench 1 is supported by legs 9, and a main box 10 is provided at the bottom thereof. The automatic feeding mechanism 2 is controlled by an electric control signal of the main box 10 to feed the reed strip 13, and the conveying and cutting mechanism 3 continuously cuts the reeds on the reed strip 13. The main box 10 is provided with a control switch button 11 and a touch display screen 12. The control switch button 11 is composed of a start button, a stop button, a reset button and an emergency stop button. During normal operation, the emergency stop switch is in a closed state; the configuration of the touch display screen 12 realizes convenient operation of the human-machine interface, greatly saves manpower, and improves production efficiency.

[0024] The automatic feeding mechanism 2 includes a support frame 201, the upper part of the support frame 201 is fixedly connected to a first servo motor 202, the output end of the first servo motor 202 is fixedly connected to a material belt fixing wheel 203, a material belt separation paper peeling mechanism is provided at the rear side of the support frame 201, and the front side of the support frame 201 is slidably connected to a liftable support platform 204 for carrying the spring strip 13. By adjusting the position of the support platform 204, the conveyed spring strip 3 can cooperate with the conveying mechanism 4 to realize horizontal conveyance, and the material belt separation paper peeling mechanism realizes the peeling of the separation paper on the spring strip 13.

[0025] Specifically, the strip separator paper peeling mechanism includes two parallel slide bars 205 fixedly connected to the rear side of the support frame 204, the slide bars 205 are slidably connected to the slider 206, the slider 206 is rotatably connected to the rotating wheel 207, the end of the slide bar 205 is provided with a limit block 208, the rotating wheel 207 is used to peel off the separator paper on the spring strip 13, and the peeled spring strip 13 is transmitted to the transmission and cutting mechanism 3 through the support table 204. By adjusting the position of the slider 206 on the slide bar 205, the separator paper on the spring strip 13 is separated and hung on one side of the rotating wheel 207. During the rotation of the first servo motor 202, the transmission mechanism 4 continuously transports the spring strip 13, and during the transportation process, the separator paper of the spring strip 13 is continuously peeled off. When peeling the separator paper of the spring strip 13, if the rotating wheel 207 is too close to the strip fixing wheel, the peeling effect is poor and the material is easily accumulated to form a jam. If the distance is too far, the spring strip is easily pulled, affecting the subsequent cutting effect.

[0026] Furthermore, the conveying mechanism 4 includes a second servo motor 401, the output end of the second servo motor 401 is fixedly connected to a rotating shaft 402, the rotating shaft 402 is rotatably connected to two bearing seats 403 installed on the cutting table 6, two feeding gears 404 for conveying the spring strip 13 are installed on the rotating shaft 402 between the bearing seats 403, and the second servo motor 401 is fixedly connected to one of the bearing seats 403. The conveying mechanism 4 also includes a conveying track 405 for conveying the spring strip 13, and the conveying track 405 is arranged between the two bearing seats 403. The spring strip 13 after the separation paper is peeled off is conveyed along the conveying track 405, the second servo motor 401 drives the feeding gear 404 to rotate, and the teeth on the feeding gear 404 move the holes on the side of the spring strip 13, driving the spring strip 13 to make a linear motion as a whole.

[0027] The cutting mechanism 5 includes a positioning platform 501, and positioning rods 502 are provided at the four corners of the bottom of the positioning platform 501. A downward-pressing cylinder 503 is provided on the positioning platform 501. The end of the downward-pressing cylinder 503 passes through the positioning platform 501 and is connected to the movable platform 504. The movable platform 504 is slidably connected to the positioning rod 502. The side of the movable platform 504 is fixedly connected to the cross-cutting cylinder 505. The end of the cross-cutting cylinder 505 is fixedly connected to the cutting knife 506. The positioning rods 502 are fixedly connected to the cutting platform 6 in groups of two and are in the same straight line with the bearing seat 403. The bottom of the movable platform 504 is fixedly connected to a positioning block 507. A slide groove 508 is provided in the middle of the positioning block 507. The cutting knife 506 is slidably connected in the slide groove 508. The opening of the slide groove 508 is provided with a positioning seat 509 with adjustable position. The positioning seat 509 is provided with a positioning pin 510. The downward pressing cylinder 503 drives the sliding table to move downward, and the positioning pin 510 on the positioning seat 509 is used to position the hole on the reed strip 13 to achieve precise positioning. The cross-cutting cylinder 505 drives the cutting knife 506 to perform a cross-cutting action. The reed strip 13 after downward pressing and positioning is close to the positioning seat 509. The reed strip cut by the cutting knife 506 falls off and falls into the receiving box 7. Then, the reed strip 13 continues to move forward under the action of the conveying mechanism 4 to cut the next reed. The downward pressing cylinder 503 and the cross-cutting cylinder 505 can adjust the positioning depth and cutting degree of the reed product.

[0028] Place the connector reed strip 13 to be cut on the strip fixing wheel 203, remove the separator paper from the material tray and place it on the rotating wheel 207, and place the reed strip 13 after peeling off the separator paper on the conveying track 405 of the conveying mechanism 4 through the support table 204. Press the start button to start the equipment, and the second servo motor 401 drives the feeding gear 404 to rotate and then drives the reed strip 13 forward. The downward pressing cylinder 503 is pressed down to position, and the cross-cutting cylinder 505 continuously cuts the reeds on the reed strip 13. After cutting a certain number of reeds, the drawer 8 can be pulled to take out the cut reeds. The present invention can complete the reed cutting relatively smoothly and quickly, avoid scratching the product, knock off the coating, and improve product quality.
