[0027] refer to Figure 1The present application provides a four-axis automatic material receiving device for tape winding, including a four-axis winding mechanism, an active rubber roller mechanism and an automatic material receiving mechanism. The four-axis winding mechanism includes a turntable 11 and four winding shafts 111 arranged on the turntable 11. The turntable 11 rotates so that the four winding shafts 111 are circulated through the winding work station 101, the material tail work station 102, the unloading work station 103 and the upper reel work station 104 respectively. The winding shaft 111 is sleeved with a reel at the upper reel work station 104. The active rubber roller mechanism includes an active rubber roller 21, and the active rubber roller mechanism is used to make the active rubber roller 21 rotate to feed and press against the reel located at the winding work station 101. The automatic material receiving mechanism is used to cut the tape and attach the tape head to the reel sleeved on the winding shaft 111 located at the winding work station 101.

[0028] The present application utilizes a four-axis winding mechanism that circulates through the winding work station 101, the material collection tail station 102, the unloading station 103 and the upper roll station 104 respectively, so that the winding work station 101 can continue to carry out the winding work, the wound roll is collected at the material collection tail station 102, unloaded at the unloading station 103, and a new roll is installed at the upper roll station 104, thereby improving the winding efficiency; the active rubber roller 21 of the active rubber roller mechanism rotates to feed the material and presses it on the roll located at the winding work station 101, which is helpful to avoid residual bubbles on the tape; the automatic material connection mechanism cuts the tape and attaches the tape head to the roll, so that the winding shaft 111 can automatically connect the material, thereby further improving the winding efficiency.

[0029] As an embodiment of the automatic material receiving mechanism, Figure 2 As shown, the automatic material receiving mechanism includes a mounting seat 31, a first driving cylinder 32, a second driving cylinder 33, a swing frame 34, a rotating shaft 35, a horizontal guide groove 36, a gear rack structure, a cutter assembly and a small rubber roller 39. The first driving cylinder 32 is hingedly mounted on the mounting seat 31, the second driving cylinder 33 is fixedly mounted on the mounting seat 31, the swing frame 34 is fixedly connected to the rotating shaft 35, the driving end of the first driving cylinder 32 is hinged to the swing frame 34, the driving end of the second driving cylinder 33 is rotatably sleeved on the rotating shaft 35, the horizontal guide groove 36 is opened on the mounting seat 31, the rotating shaft 35 is penetrated by the horizontal guide groove 36, the gear rack structure includes a gear 371 and a rack 372 meshing with each other, the gear 371 is fixedly mounted on the rotating shaft 35, the rack 372 is fixedly mounted on the mounting seat 31, and the cutter assembly and the small rubber roller 39 are mounted on the swing frame 34.

[0030] The working process of the automatic material receiving mechanism is controlled by a set program. When there is a new roll at the winding work station 101, the first driving cylinder 32 first works to make the swing frame 34 swing and drive the cutter assembly and the small rubber roller 39 to approach the roll. The small rubber roller 39 presses the tape (the sticky side faces the roll) onto the roll, and then the cutter assembly works to cut the tape. Then the second driving cylinder 33 works to move the rotating shaft 35 along the horizontal guide groove 36. The swing frame 34 is fixedly connected to the rotating shaft 35, so the swing frame 34 also translates together. Since the gear 371 on the rotating shaft 35 is engaged with the rack 372 on the mounting seat 31, the rotating shaft 35 will also rotate a certain angle, so the swing frame 34 also swings a certain angle, and the small rubber roller 39 follows the action of the swing frame 34 and can move along the outer circumference of the roll, thereby smoothing the material head and sticking it to the roll, thus completing the material receiving of the roll.

[0031] Specifically, a rotating bearing 351 is sleeved on the rotating shaft 35, and the outer ring of the rotating bearing 351 is slidably installed in the horizontal guide groove 36. Such an arrangement can prevent the rotating shaft 35 from being worn.

[0032] Specifically, the cutter assembly includes a rodless cylinder 382 and a cutter 381 disposed at the working end of the rodless cylinder 382 .

[0033] As an embodiment of the active rubber roller mechanism, the active rubber roller mechanism includes a rotation drive component for driving the active rubber roller 21 to rotate and a push drive component for driving the active rubber roller 21 to press against the reel shaft 111 located at the reeling work station 101. Figure 1 and Figure 3 As shown, the rotation drive assembly includes a servo drive motor 221. The horizontal push drive assembly includes a frame 231, a linear guide 232, a mobile plate 233, a third drive cylinder 234, a fourth drive cylinder 235 and a swing rod 236. The linear guide 232 is arranged on the frame 231, the mobile plate 233 is slidably mounted on the linear guide 232, the active rubber roller 21 and the rotation drive assembly are arranged on the mobile plate 233, the third drive cylinder 234 is hinged on the frame 231, the swing rod 236 is rotatably mounted on the frame 231 in the form of a lever, one end of the swing rod 236 is hinged to the driving end of the third drive cylinder 234, the other end of the swing rod 236 is hinged to the fourth drive cylinder 235, and the driving end of the fourth drive cylinder 235 is hinged to the mobile plate 233.

[0034] Based on the embodiment of the automatic material receiving mechanism and the embodiment of the active rubber roller mechanism, the mounting seat 31 and the movable plate 233 can be integrally provided.

[0035] As an embodiment 1 of the four-axis winding mechanism, Figure 4As shown, the four-axis winding mechanism includes a winding shaft driving member for driving the winding shaft 111 to rotate relative to the rotating disk 11, and the winding shaft driving member includes a first active sprocket 1211, a first driven sprocket 1212, a first chain 1213, a first chain tensioning wheel 1214, a first chain guide wheel 1215, a second active sprocket 1221, a second driven sprocket 1222, a second chain 1223, a second chain tensioning wheel 1224, a second chain guide wheel 1225 and a magnetic powder clutch 123; the four winding shafts 111 are evenly spaced around the rotation axis of the rotating disk 11 to form two winding shaft groups with two winding shafts 111 arranged opposite to each other, and the two winding shafts 111 of one winding shaft group are respectively connected by a magnetic powder clutch 123 The first driven sprocket 1212 is connected, and the two winding shafts 111 of the other winding shaft group are respectively connected to the second driven sprocket 1222 through the magnetic powder clutch 123. A central shaft is provided at the rotation axis of the turntable 11, and the first driving sprocket 1211 and the second driving sprocket 1221 are rotatably installed on the central shaft. The first chain 1213 is wound around the first driving sprocket 1211, the two first driven sprockets 1212, the first chain guide wheel 1215 and the first chain tensioning wheel 1214, and the second chain 1223 is wound around the second driving sprocket 1221, the two second driven sprockets 1222, the second chain guide wheel 1225 and the second chain tensioning wheel 1224.

[0036] It can be understood that by controlling the rotation of the first active sprocket 1211, two oppositely disposed winding shafts 111 can be driven to rotate at the same time, and by controlling the rotation of the second active sprocket 1221, the other two oppositely disposed winding shafts 111 can be driven to rotate at the same time, so that each winding shaft 111 can rotate relative to the turntable 11. Since each winding shaft 111 is provided with a magnetic powder clutch 123, the winding shaft 111 not working at the winding work station 101 can be disconnected from the transmission by the magnetic powder clutch 123 and not rotate, and only the winding shaft 111 working at the winding work station 101 can be connected to the transmission by the magnetic powder clutch 123 and rotate.

[0037] As a second embodiment of the four-axis winding mechanism, Figure 4 and Figure 5As shown, the four-axis winding mechanism includes a first rotating disk 11a and a second rotating disk 11b, and the two ends of the winding shaft 111 are mounted on the first rotating disk 11a and the second rotating disk 11b in a one-to-one correspondence. A first sleeve 131 is arranged on the first rotating disk 11a, and an external shaft 132 is rotatably mounted in the first sleeve 131. The external shaft 132 is provided with a connecting groove 1321 for connecting the first end of the winding shaft 111. The winding shaft 111 is connected to the first sleeve 131 through a bearing, and a joint bearing 133 is movably arranged in the first sleeve 131. The joint bearing 133 is provided in the first sleeve 131. The bearing 133 is sleeved on the winding shaft 111, and the side wall of the first sleeve 131 is provided with a first notch 1311 for avoiding the first end of the winding shaft 111; a second sleeve 134 is provided on the second turntable 11b, and a bearing sleeve 135 is slidably installed in the second sleeve 134, and the bearing sleeve 135 is connected to the winding shaft 111 through a bearing, and a tightening cylinder 136 is connected to the end of the bearing sleeve 135 away from the winding shaft 111, and the side wall of the second sleeve 134 is provided with a second notch 1341 for avoiding the second end of the winding shaft 111.

[0038] It can be understood that, in the normal state, the tightening cylinder 136 tightens the bearing sleeve 135, and the second end of the winding shaft 111 is inserted into the bearing sleeve 135. Under the action of the tightening cylinder 136, the first end of the winding shaft 111 is inserted into the connecting groove 1321 of the external shaft 132. When the reel is taken out at the unloading station 103 and a new reel is inserted into the upper reel station 104, the tightening cylinder 136 is retracted, and the second end of the winding shaft 111 leaves the bearing sleeve 135. The winding shaft 111 is not tightened and the first end can be separated from the connecting groove 1321 of the external shaft 132. Due to the arrangement of the joint bearing 133 and the first notch 1311 on the side wall of the first sleeve 131, the second end of the winding shaft 111 can be broken out from the second notch 1341 of the second sleeve 134. After being broken out, the winding shaft 111 can be unloaded from the second end or a new reel can be inserted.

[0039] The first embodiment of the four-axis winding mechanism can be combined with the second embodiment. In this case, the external shaft 132 is connected to the first driven sprocket 1212 or the second driven sprocket 1222 through the magnetic powder clutch 123 .

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments only express several implementation methods of the present application and should not be construed as limiting the scope of the patent application. It should be noted that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be subject to the attached claims.
