[0002] In the production process of SMT (surface mount technology), the tape is the key carrier for storing sheet components, and its management efficiency is crucial to the operating efficiency of the entire production line and material cost control. With the continuous expansion of production scale, in order to meet the customized and personalized production needs, manufacturers are faced with the challenge of small batches and multiple types of production work orders. Specifically, a roll of tape material usually encapsulates a large number of components, but the actual number of work orders used is often less than the total amount of a roll of material. In order to achieve more refined management, the original tape material needs to be repacked according to the actual number of work orders.

[0003] The emergence of SMT tape shearing devices has greatly improved the automation of tape processing, realized automatic counting and cutting of tapes, and significantly improved production efficiency. However, the existing shearing devices use a cylinder to drive the cutter vertically downward for shearing. Although this method is simple, it often has problems such as low shearing accuracy and easy shearing misalignment. At the same time, since the cutter is in direct contact with the tape and is subjected to a large shearing force, the cutter is prone to wear and has a relatively short service life, which not only increases the equipment maintenance cost, but also affects production efficiency and product quality.

[0004] Therefore, there is an urgent need for a circular cutting knife mechanism for slitting material strips that supports high shearing accuracy and long service life. Utility Model Content

[0032] See attached Figure 1 To Attachment Figure 7 , the figure shows a specific embodiment of a circular cutting knife mechanism for slitting material strips provided by the utility model.

[0033] See attached Figure 1 and attached Figure 2 , the circular cutter mechanism for slitting the strip includes:

[0034] A material belt track 1, on which a material belt slot 110 is formed, the material belt slot 110 is used to place the material belt, and a cutting slot 120 is provided on the material belt track 1;

[0035] A cutter assembly 2 is arranged close to the material belt track 1, and the cutter assembly 2 is provided with a circular cutter 210, which is arranged vertically and can rotate with its own circle center as an axis;

[0036] The translation assembly 3 connected to the cutter assembly 2 is used to drive the circular cutter 210 to translate along the opening direction of the cutting groove 120 to cut the material strip located in the material strip groove 110 .

[0037] See attached Figure 2 and attached Figure 3 In the above embodiment, the slitting groove 120 is set at a certain angle to the material belt groove 110. During the working process, the material belt moves in the material belt groove 110 of the material belt track 1 and is located above the slitting groove 120. The cutter assembly 2 located on one side of the material belt track 1 moves horizontally under the drive of the translation assembly 3. During the movement, the circular cutter 210 of the cutter assembly 2 rotates with its own center of circle as the axis, rotates and translates along the opening direction of the slitting groove 120, and cuts the material belt located in the material belt groove 110, thereby realizing the slitting of the material belt. In an optional embodiment, a motor can be set in the cutter assembly 2 to drive the circular cutter 210 to rotate and cut. In this embodiment, the circular cutter 210 is rolling cutting during the translation process. In this embodiment, the circular cutter 210 cooperates with the slitting groove 120 on the material belt track 1 to ensure the accuracy and stability of the cutting path. The circular cutter 210 can move accurately along the direction of the slitting groove 120 to complete the slitting action.

[0038] See attached Figure 3 In the above embodiment, the material belt track 1 includes a first track segment 130 and a second track segment 140 close to each other, and a slitting groove 120 is formed between the first track segment 130 and the second track segment 140. The opening direction of the slitting groove 120 is perpendicular to the length direction of the material belt groove 110. In the embodiment, the material belt track 1 divides the material belt track 1 into two at the slitting groove 120, which is formed at the first track segment 130 and the second track segment 140. The material belt crosses the slitting groove 120 between the first track segment 130 and the second track segment 140. When the circular cutter 210 rolls and slides over the slitting groove 120, the material belt can be cut. The material belt groove 110 in this embodiment is a groove that penetrates the material belt track 1 from top to bottom. In some optional embodiments, the material belt groove 110 can also be a non-through groove with a depth greater than the material belt groove 110. The opening direction of the slitting groove 120 is perpendicular to the length direction of the material strip groove 110, which can ensure that the cuts of the material strip after slitting are regular and avoid damage to the electronic components in the material strip.

[0039] See attached Figure 5 and attached Figure 6In the above embodiment, a bearing assembly 4 is further included. The bearing assembly 4 is disposed between the first track segment 130 and the second track segment 140 and corresponds to the bottom of the slitting groove 120, and is used to bear the circular cutter 210 when the circular cutter 210 slits the material strip. The bearing assembly 4 includes a bearing bar 410, and a bearing groove 411 is provided at the top of the bearing bar 410. The bearing groove 411 corresponds to the slitting groove 120, and a part of the circular cutter 210 is located in the bearing groove 411. In the embodiment, when slitting the material strip, the bearing groove 411 ensures the stability and accuracy of the circular cutter 210 during the cutting process, reduces the vibration and deviation of the circular cutter 210, and avoids the cutting deviation caused by the shaking of the circular cutter 210.

[0040] See attached Figure 4 and attached Figure 6 In the above embodiment, the bearing assembly 4 further includes a first driving device 420 and a carrier plate 430 connected to each other, and the bearing strip 410 is mounted on the carrier plate 430. The first driving device 420 drives the bearing strip 410 to move vertically through the carrier plate 430 to approach or move away from the material strip track 1. In the embodiment, when cutting the material strip, the first driving device 420 drives the bearing strip 410 to move upward along the position of the cutting groove 120 until it is slightly higher than the plane where the inner bottom surface of the material strip groove 110 is located, that is, the bearing strip 410 slightly lifts the material strip located in the material strip groove 110, so that the material strip is lifted by the bearing strip 410 in the cutting groove 120 to form a slight arch; then, the circular cutter 210 rolls and slides across the cutting groove 120 to cut the material strip. Since a part of the blade at the bottom end of the circular cutter 210 is located in the bearing groove 411, the material strip can be easily cut, effectively avoiding the wear of the circular cutter 210 or damage to the material strip. In the embodiment, the first driving device 420 and the material belt track 1 are both installed on the bottom plate 6 . When the first driving device 420 is driven, the supporting bar 410 and the supporting plate 430 move upward relative to the base 8 .

[0041] See attached Figure 5 In the above embodiment, the translation assembly 3 and the cutter assembly 2 are installed on the carrier 430 to move vertically with the carrier 430, and a slide rail 5 is installed between the translation assembly 3 and the carrier 430, so that the translation assembly 3 can move horizontally relative to the carrier 430. In the embodiment, the translation assembly 3 and the cutter assembly 2 are connected to the carrier 430, so that when the first driving device 420 drives the carrier 430 and the bearing bar 410 to move, the circular cutter 210 of the cutter assembly 2 and the bearing bar 410 are always in a state of relative height fixation. By installing the slide rail 5 between the translation assembly 3 and the carrier 430, the translation assembly 3 can move horizontally, that is, the effect of horizontally cutting the material strip is achieved. In the embodiment, the first driving device 420 is a cylinder.

[0042] See attached Figure 4In the above embodiment, the translation assembly 3 includes a moving plate 310 and a second driving device 320, the second driving device 320 is used to drive the moving plate 310 to move, and the cutter assembly 2 is installed at one end of the moving plate 310 close to the material belt track 1. In the embodiment, the second driving device 320 is fixedly arranged on the moving plate 310, and the power output end of the second driving device 320 is connected with a translation gear 330, and a rack 431 is provided on the carrier plate 430, and the translation gear 330 and the rack 431 are meshed. When the second driving device 320 drives the translation gear 330 to rotate, since the carrier plate 430 can only move up and down, the moving plate 310 of the translation assembly 3 moves laterally along the slide rail 5. In the embodiment, the second driving device 320 is a motor.

[0043] See attached Figure 7 In the above embodiment, the cutter assembly 2 includes a bearing 220 installed in the moving plate 310 and a rotating shaft 230 extending from the bearing 220 to the side of the moving plate 310. The end of the rotating shaft 230 is provided with a first stop block 240 and a second stop block 250 detachably mounted on the first stop block 240. The circular cutter 210 is installed between the first stop block 240 and the second stop block 250. In the embodiment, the second driving device 320 is fixedly arranged at one end of the moving plate 310 away from the material belt track 1, and the cutter assembly 2 is fixedly arranged at one end of the moving plate 310 close to the material belt track 1. The bearing 220 is located in the moving plate 310, and the circular cutter 210 is located at the side of the moving plate 310. In the embodiment, the first limit block 240 and the second limit block 250 are both circular, and their diameters are slightly smaller than the diameter of the circular cutter 210, ensuring that only a small part of the circular cutter 210 close to the blade is located outside the encirclement of the first limit block 240 and the second limit block 250, making the circular cutter 210 more stable and avoiding cutting deviations caused by shaking during the slitting process.

[0044] In summary, the present embodiment provides a circular cutter mechanism for slitting material strips, wherein the circular cutter 210 cooperates with the slitting groove 120 on the material strip track 1 to ensure the accuracy and stability of the cutting path, and the circular cutter 210 can accurately move along the direction of the slitting groove 120 to complete the slitting action; by setting the supporting bar 410 and the supporting groove 411, effective support for the circular cutter 210 during the cutting process is achieved to avoid vibration and deviation of the cutter; the supporting bar 410 is driven by the first driving device 420 to be close to the material strip track 1, so as to facilitate the support of the material strip during the slitting process; the circular cutter 210 is installed by combining a detachable second limit block 250 with a first limit block 240, so as to facilitate the replacement and maintenance of the circular cutter 210; the present embodiment realizes precise slitting of the material strip through the rotation and translational movement of the circular cutter 210, which not only improves the shearing accuracy, but also reduces the wear of the cutter and prolongs its service life.
