DETAILED DESCRIPTION

[0031] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to various alternative embodiments as well. The following description is not limited to the exemplary embodiments, but rather, is applicable to any apparatus and method consistent with the present application as outlined in the appended claims.

[0032] As Figure 1As shown, including the preparation unit 1, the preparation unit 1 discharging position is provided with cutting unit 2, the other side of cutting unit 2 is provided with the correction unit 3, the other side of correction unit 3 is provided with the placement table 4, the side of placement table 4 is provided with parallel stroke mechanism 5, the jaw 6 is provided on stroke mechanism 5, the tail of placement table 4 is provided with throwing unit 7, the sensor is installed at the bottom of placement table 4, the sensor here can be photoelectric sensor, the installation position of photoelectric sensor is determined according to the length of the isolation strip, that is, the distance between photoelectric sensor and the tail of placement table 4 is the specified length of the isolation strip, here the tail of placement table 4 is the end close to throwing unit 7. Stroke mechanism 5 here adopts servo slide rail, which can realize linear reciprocating motion, and jaw 6 can move on servo slide rail. Jaw 6 moves to the preparation unit 1, pulls the isolation strip from the preparation unit 1 to the specified length, and is pressed and cut by the pressing mechanism and cutting mechanism in the cutting unit 2, one end of the isolation strip is the tail, and the other end is the head. The cut isolation strip is placed on the placement table 4, the tail of the isolation strip is pulled to the tail of the placement table 4, and when the head of the isolation strip does not block the photoelectric sensor, the length of the isolation strip is too short, which is unqualified, and the throwing unit 7 throws the unqualified isolation strip, and the subsequent workers collect the unqualified isolation strip.

[0033] As Figure 2As shown, the preparation unit 1 includes a preparation support 101 and a moving mechanism capable of driving the preparation support 101 to move, the moving mechanism including an A motor 102, a belt and an A track 103, the preparation support 101 being slidingly arranged on the A track 103, the belt being connected to the preparation support 101, and the A motor 102 driving the belt to rotate to realize the movement of the preparation support 101. The preparation support 101 is provided with mounting rods 105, and preparation mechanisms 104 are respectively mounted on the mounting rods 105, the ends of the mounting rods 105 being blocked and fixed to the preparation mechanisms 104 by plugs, the preparation mechanisms 104 being composed of a plurality of preparation discs, and isolation strips being wound on the preparation discs. The preparation mechanisms 104 in the figure are symmetrically arranged, and according to requirements, 3 groups, 4 groups, 5 groups or any group can be arranged; meanwhile, each group of preparation mechanisms 104 is composed of 3 preparation discs, and according to requirements, 4, 5, 6 or any number of preparation discs can be arranged. In use, the A motor 102 works to control the preparation support 101 to move along the A track 103, so that one of the preparation mechanisms 104 in one group moves to the cutting unit 2 and stops, and the clamping jaw 6 pulls the isolation strip from the preparation disc to cut. When the isolation strips on the preparation disc are used up, the A motor 102 works again to move another preparation disc in the group to the cutting unit 2 and stop, and the clamping jaw 6 pulls again to cut. When the isolation strips on the preparation mechanism 104 are all used up, the A motor 102 works to move the preparation disc on another group of preparation mechanisms 104 to the cutting unit 2 and stop, and the above steps are repeated. At this time, the worker can remove the plug to replace the used preparation mechanism 104, without stopping the machine for replacement, thereby improving the production efficiency.

[0034] As shown in Figure 3 and Figure 4 As shown, the throwing unit 7 includes a C track 705, the C track 705 being provided with sliding blocks of different heights, and the throwing groove 702 being mounted on the sliding blocks, so that the throwing groove 702 can be downwardly inclined. The sliding blocks are mounted on a throwing support 701, the bottom of the throwing support 701 being fixedly connected with a conveying belt, both ends of the conveying belt being provided with rotating wheels, a C motor 706 being connected with one of the rotating wheels, and the C motor 706 driving the rotating wheel to rotate to realize the driving rotation of the conveying belt. A driving wheel 707 and a driven wheel 708 are respectively arranged on the throwing support 701 from bottom to top, the throwing support 701 being provided with a B motor 704, the output end of the B motor 704 being connected with the conveying belt, and the other end of the conveying belt being connected with the driving wheel 707. Meanwhile, a waist hole is arranged on the throwing support 701, the driven wheel 708 being mounted on the throwing support 701 through the waist hole, so that the driven wheel 708 can move in the waist hole. Furthermore, the driven wheel 708 is connected with the throwing support 701 through a B tension spring 709, so that the driven wheel 708 can always be in close contact with the driving wheel 707.

[0035] In actual production, the length of the isolation strip is usually only too short, but not too long. The cut isolation strip is laid on the placement table 4, and when the tail end of the isolation strip does not shield the sensor, it means that the length of the isolation strip is too short and is considered unqualified. At this time, the C motor 706 works to drive the material throwing bracket 701 to move along the C rail 705 towards the placement table 4, and when the isolation strip contacts the middle of the driving wheel 707 and the driven wheel 708, the B motor 704 starts to work to drive the driving wheel 707 to start rotating, and the isolation strip is thrown into the material throwing groove 702 through rotation. The obliquely arranged material throwing groove 702 enables the isolation strip to slide more smoothly into the designated collection box.

[0036] As shown in Figure 1 In order to better contact the isolation strip with the middle of the driving wheel 707 and the driven wheel 708, a track is arranged at the bottom of the tail end of the placement table 4, so that the tail end of the placement table 4 is installed on the track through a sliding block. When the unqualified isolation strip appears, the placement table 4 moves towards the cutting unit 2, so that the tail of the isolation strip is exposed, so that the isolation strip can be more easily contacted with the driving wheel 707 and the driven wheel 708 when they move, and the material throwing of the isolation strip is more convenient.

[0037] As shown in Figure 3 A tensioning wheel 703 is arranged on the material throwing bracket 701, which can move on the material throwing bracket 701 to adjust the tension of the conveying belt.

[0038] As shown in Figure 5 and Figure 6 The regulating unit 3 includes a base 309, the base 309 is provided with a B rail 307 which is perpendicular to the placement table 4, and symmetrical regulating blocks 302 are arranged on the B rail 307, the two regulating blocks 302 are connected by an A tension spring 308, and limiting rollers 303 are arranged on the regulating blocks 302. A panel 301 which is in the same horizontal plane as the placement table 4 is arranged above the base 309 through a connecting column, a waist hole in the same direction as the B rail 307 is formed in the panel 301, and the limiting rollers 303 extend from the waist hole. An A cylinder 304 is arranged on the base 309, and a wedge block 305 is connected to the output end of the A cylinder 304.

[0039] When the isolation strip is pulled to the standardizing unit 3, the A cylinder 304 drives the wedge block 305 to extend into the two standardizing blocks 302, and the two standardizing blocks 302 are moved outward along the B rail 307 by extrusion, thereby expanding the distance between the two limiting rollers 303, and the limiting rollers 303 are fixed by the action of the A tension spring 308, so that the clamping jaw 6 can be pulled to move to the placement table 4, avoiding the clamping jaw 6 from passing through. When the clamping jaw 6 passes through the standardizing unit 3, the A cylinder 304 drives the wedge block 305 to retract, so that the two limiting rollers 303 return to the original state and are attached to the two sides of the isolation strip to limit it.

[0040] In order to facilitate the wedge block 305 to extend into the two standardizing blocks 302, a roller 306 is arranged on the standardizing block 302 in contact with the wedge block 305, which can avoid friction between the wedge block 305 and the standardizing block 302 by rolling of the roller 306.

[0041] As shown in Figure 7 and Figure 8 , the cutting unit 2 includes a cutting mechanism and a pressing mechanism. The cutting mechanism includes a total bracket 207, a vertical rail is arranged on the total bracket 207, a mounting plate 212 is connected to the rail through a sliding block, an E cylinder 206 is arranged on the total bracket 207, the output end of the E cylinder 206 is connected to the mounting plate 212, and the E cylinder 206 can drive the mounting plate 212 to move up and down along the rail. A blocking block 209 is arranged on the mounting plate 212, and an adjusting screw 210 is arranged on the total bracket 207 corresponding to the blocking block 209. By rotating the adjusting screw 210, the lowest point distance of the descending of the mounting plate 212 can be adjusted, which can be the height of the mounting plate 212 during cutting. A horizontal rail is arranged on the front of the mounting plate 212, a cutting bracket 208 is connected to the rail through a sliding block, an F cylinder 211 is arranged on the back of the mounting plate 212, the output end of the F cylinder 211 is connected to the cutting bracket 208, and the F cylinder 211 can drive the cutting bracket 208 to move horizontally along the rail. A C cylinder 204 is installed on the top of the cutting bracket 208, a cutter 213 is arranged on the output end of the C cylinder 204, and the C cylinder 204 controls the cutter 213 to move up and down to cut the isolation strip. The pressing mechanism includes a pressing bracket 201, which is installed on the mounting plate 212 on one side of the cutting bracket 208. A B cylinder 203 is arranged on the pressing bracket 201, and a pressing head 202 is arranged on the output end of the B cylinder 203. When the isolation strip is pulled to a specified length, the B cylinder 203 controls the pressing head 202 to descend to press the isolation strip, avoiding movement during cutting and improving the accuracy of cutting. A rail perpendicular to the placement table 4 is arranged below the total bracket 207, the bottom of the total bracket 207 is connected to the rail through a sliding block, and a D cylinder 205 drives the total bracket 207 to move on the rail.

[0042] When the isolation strips in the standby tray are all used up and the next standby tray needs to be replaced, the clamping jaw 6 needs to be moved to the standby tray to pull the isolation strips out of the standby tray, at this time the cutting unit 2 needs to be moved to make room for the clamping jaw 6 to move. The piston rod of the D cylinder 205 is retracted to drive the total bracket 207 to move, the E cylinder 206 drives the mounting plate 212 to descend, and the piston rod of the F cylinder 211 is retracted to drive the cutting bracket 208 to move, thereby making room for the clamping jaw 6. After the clamping jaw 6 moves to the placement table 4, the components on the cutting unit 2 return to the specified positions.

[0043] In specific work, the cutting unit 2 makes room for the clamping jaw 6, the travel mechanism 5 controls the clamping jaw 6 to move to the standby tray to grab the isolation strips, and after the isolation strips are moved to the placement table 4, the regulating unit 3 regulates the isolation strips. When the clamping jaw 6 pulls the isolation strips to the specified length, the clamping jaw 6 stops moving, the pressing head 202 presses the isolation strips, and the cutter 213 cuts the isolation strips. The sensor detects, when the length meets the requirements, then waits for the external moving mechanism to move the isolation strips to the next station for processing. When the length does not meet the requirements, the C motor 706 works to drive the material throwing bracket 701 to move along the C track 705 towards the placement table 4. When the isolation strips contact the middle of the driving wheel 707 and the driven wheel 708, the B motor 704 starts to work to drive the driving wheel 707 to start rotating, and the isolation strips are thrown into the material throwing groove 702 through rotation. Repeat the above steps.

[0044] After being used for a period of time, when the isolation strips on the standby tray are used up and the standby tray needs to be replaced, the A motor 102 drives the standby bracket 101 to move, and the standby tray with isolation strips is moved to the cutting unit 2, and the previous working steps can be repeated. When the isolation strips on the standby mechanism 104 are all used up, the A motor 102 works to move the standby tray on the other group of standby mechanisms 104 to the cutting unit 2. At this time, the worker can remove the plug and replace the used standby mechanism 104.
