DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0030] Please refer to Figures 1 to 4 A core lug alignment mechanism 10, the core 100 includes a core body 110 and a lug 120 leading out from the end face of the core body 110, comprising: a rotating clamping wheel set 200 and a lug detection module 300,

[0031] The rotating clamping wheel set 200 includes a driving wheel 210, a driven wheel 220 and a pressing wheel 230, the driving wheel 210, the driven wheel 220 and the pressing wheel 230 are in a triangular structure to clamp the core 100 in the middle;

[0032] The lug detection module 300 includes two sets of position sensors 310, and the two sets of position sensors 310 are respectively used for sensing the position of the lug 120.

[0033] The driving wheel 210 drives the core body 110 to rotate along the axis until the lug 120 rotates to a preset angle and is detected by the two sets of position sensors 310.

[0034] It should be noted that the three wheels of the driving wheel 210, the driven wheel 220 and the pressing wheel 230 are arranged in a triangular shape to jointly clamp the core 100. The driving wheel 210 is usually driven by a motor and is responsible for rotating the core 100. The driven wheel 220 cooperates with the driving wheel 210 to help the core 100 rotate stably. The pressing wheel 230 is located between the driving wheel 210 and the driven wheel 220 and is used to apply appropriate pressure to the core 100 to ensure that the core 100 does not displace or shake during rotation. The tab detection module 300 includes two groups of position sensors 310, which are respectively installed on both sides of the rotating clamping wheel set 200 or at appropriate positions, and are used to sense the position of the tab 120. These two groups of sensors can detect in real time whether the tab 120 has rotated to the preset angle and position.

[0035] The working process of the core tab alignment mechanism 10 is as follows:

[0036] S1: Core 100 placement: Place the core 100 with the tab 120 in the rotating clamping wheel set 200, ensuring that the tab 120 is in the appropriate position to be detected.

[0037] S2: Clamping and fixing: Apply pressure to the core 100 through the pressing wheel 230 to securely fix it between the driving wheel 210 and the driven wheel 220.

[0038] S3: Rotational positioning: Start the driving wheel 210 and rotate the core 100 along the axial direction. The driven wheel 220 rotates accordingly, and the pressing wheel 230 keeps the core 100 stable.

[0039] S4: Tab 120 detection: When the tab 120 rotates to the preset angle, the two groups of position sensors 310 simultaneously detect the position of the tab 120 and send signals.

[0040] S5: Stop rotating: According to the signals of the sensors, the control system stops the driving wheel 210 from rotating. At this time, the tab 120 has been accurately positioned to the preset position.

[0041] S6: Release the core 100: After positioning is completed, the pressing wheel 230 is loosened, and the core 100 can be safely removed from the rotating clamping wheel set 200, ready for the next process.

[0042] It should be noted that in order to improve production efficiency, the core tab alignment mechanism 10 can be provided with multiple rotating clamping wheel sets 200 and multiple tab detection modules 300 arranged in one-to-one correspondence to enable batch tab 120 alignment operations on the core 100.

[0043] Please refer to Figure 2 and Figure 4Further, the two sets of position sensors 310 are photoelectric sensors, and when the tab 120 rotates to the preset angle, the sensing points of the two photoelectric sensors fall on the tab 120 along the width direction.

[0044] It should be noted that the two sets of position sensors 310 are precisely installed on both sides or appropriate positions of the rotating clamping wheel set 200, so as to detect the position of the tab 120 in real time. When the tab 120 moves to the preset angle with the rotation of the core 100, the sensing points of the two photoelectric sensors will accurately fall on the tab 120 along the width direction. This means that the sensor has successfully detected the position of the tab 120 and sent a corresponding signal. The sending of this signal marks that the tab 120 has rotated to the correct position. At this time, the rotating clamping wheel set 200 will stop rotating, and the tab 120 of the core 100 is accurately corrected to the preset position. Compared with using one set of position sensors, two sets of position sensors can detect the tab 120 from different angles and positions, which increases the multidimensionality of detection, thereby improving the recognition accuracy of the position of the tab 120. When the two sets of sensors simultaneously sense the tab 120 and confirm its position, the possibility of misjudgment can be greatly reduced.

[0045] Please refer to Figure 2 and Figure 4 Further, the photoelectric sensor includes a transmitter 311 and a receiver 320, and the transmitter 311 and the receiver 320 are respectively arranged on the upper and lower sides of the rotation path of the tab 120.

[0046] It should be noted that the transmitter 311 is responsible for sending a stable light beam or signal, and the receiver 320 is responsible for receiving the light beam or signal. When the tab 120 is located between them, it will block part or all of the light beam, causing the signal of the receiver 320 to change. This change is captured by the mechanism and interpreted as a signal that the tab 120 has reached the preset position. This up-and-down photoelectric design has higher detection accuracy and reliability. Because it can eliminate errors that may be caused by changes in the surface state of the core 100 or the tab 120, light interference and other factors.

[0047] Please refer to Figure 2 and Figure 3 Further, the core tab alignment mechanism 10 further includes a support assembly 400, a first driving assembly 500, and a second driving assembly 600. The driving wheel 210 and the driven wheel 220 are arranged side by side in the horizontal direction through the support assembly 400, the first driving assembly 500 is used to drive the pressing wheel 230 to move towards or away from the core 100, and each second driving assembly 600 is used to drive the corresponding driving wheel 210 to rotate.

[0048] It should be noted that the support assembly 400 ensures that the driving wheel 210 and the driven wheel 220 can be arranged side by side in the horizontal direction, providing a stable clamping environment for the winding core 100, so that the winding core 100 can maintain balance during rotation and avoid deviation or shaking, thereby ensuring the accurate correction of the position of the tab 120. The first driving assembly 500 is responsible for driving the compression wheel 230 to move towards or away from the winding core 100. This function enables the mechanism to adapt to winding cores 100 of different sizes, ensuring that the compression wheel 230 can provide appropriate compression force to keep the winding core 100 stable during rotation. By adjusting the position of the compression wheel 230, the mechanism can easily cope with winding cores 100 of different specifications and types, improving its versatility and flexibility. The second driving assembly 600 is the key to driving the corresponding driving wheel 210 to rotate. It provides the power required for the rotation of the clamping wheel set 200, so that the driving wheel 210 can drive the winding core body 110 to rotate along its axis.

[0049] Please refer to Figure 2 and Figure 3 Further, the support assembly 400 includes a base 410, a first mounting stand 420 and a second mounting stand 430, the first mounting stand 420 and the second mounting stand 430 are arranged on the base 410, the driving wheel 210 and the driven wheel 220 are arranged side by side on the first mounting stand 420, and the second driving assembly 600 is arranged on the second mounting stand 430.

[0050] Among them, the base 410 serves as the foundation of the entire support assembly 400, used to carry and fix other components; the first mounting stand 420 is used to mount the driving wheel 210 and the driven wheel 220, so that they can rotate side by side in the horizontal direction; the second mounting stand 430 is used to mount the second driving assembly 600, which is used to drive the corresponding driving wheel 210 to rotate.

[0051] Please refer to Figure 2 and Figure 3 Further, the first driving assembly 500 is arranged on the base 410 and located on the side of the first mounting stand 420 where the driving wheel 210 and the driven wheel 220 are arranged, and the first driving member is used to drive the compression wheel 230 to move towards or away from the winding core 100 in the horizontal direction and the vertical direction.

[0052] It should be noted that the first driving assembly 500 can ensure that the compression wheel 230 can provide appropriate compression force, so that the core 100 remains stable during rotation, regardless of the size or shape of the core 100, the first driving assembly 500 can accurately adjust the position of the compression wheel 230 to ensure firm clamping of the core 100. At the same time, since the driving compression wheel 230 of the first driving assembly 500 can be quickly moved away when needed, sufficient space is provided for the feeding and discharging operation of the core 100, thereby greatly improving the production efficiency.

[0053] Please refer to Figure 1 and Figure 2 Further, the first driving assembly 500 includes a horizontal driving member 510, a horizontal sliding plate 520, a lifting driving member 530, a lifting plate 540, and a connecting member 550. The horizontal driving member 510 is arranged on the base 410, the horizontal sliding plate 520 is slidingly arranged on the base 410, and the horizontal driving member 510 drives the horizontal sliding plate 520 to move in the horizontal direction. The lifting plate 540 is arranged on the horizontal sliding plate 520 in a lifting manner, the lifting driving member 530 is used to drive the lifting plate 540 to move up and down, the connecting member 550 is arranged on one side of the lifting plate 540 close to the first mounting vertical plate 420, and the compression wheel 230 is rotatably arranged on the connecting member 550.

[0054] It should be noted that the horizontal driving member 510 provides a power source in the horizontal direction. The horizontal sliding plate 520 is slidingly arranged on the base 410 and connected with the horizontal driving member 510, and is driven by the horizontal driving member 510 to move in the horizontal direction. The lifting plate 540 is arranged on the horizontal sliding plate 520 in a lifting manner, and it is responsible for moving the compression wheel 230 in the vertical direction. The lifting driving member 530 is connected with the lifting plate 540 and provides power for the lifting movement of the lifting plate 540. In this way, the compression wheel 230 can not only move in the horizontal direction, but also move up and down in the vertical direction, further enhancing the flexibility and adaptability of the mechanism. The connecting member 550 is arranged on one side of the lifting plate 540 close to the first mounting vertical plate 420, which serves to connect the lifting plate 540 and the compression wheel 230. The compression wheel 230 is rotatably arranged on the connecting member 550, which enables it to rotate stably and provide appropriate compression force when needed.

[0055] Please refer to Figure 1 and Figure 2 Further, the horizontal sliding plate 520 is slidingly connected with the base 410 through a first sliding rail 560, and the lifting plate 540 is liftingly connected with the horizontal sliding plate 520 through a guide column 570.

[0056] It should be noted that the first sliding rail 560 provides a stable and smooth sliding path for the horizontal sliding plate 520, ensuring that the horizontal sliding plate 520 can move smoothly in the horizontal direction under the drive of the horizontal drive 510. The use of the first sliding rail 560 not only enhances the stability of the mechanism, but also improves the accuracy and reliability of the movement of the horizontal sliding plate 520. At the same time, the guide column 570 provides a stable lifting path for the lifting plate 540. The lifting drive 530 drives the lifting plate 540 to move up and down along the guide column 570, achieving the position adjustment of the compression wheel 230 in the vertical direction. The design of the guide column 570 ensures the stability and accuracy of the lifting plate 540 during the lifting process, so that the compression wheel 230 can accurately move to the desired position.

[0057] Please refer to Figure 2 and Figure 4 Further, the tab detection module 300 further includes a mounting block 320, the mounting block 320 is arranged on one side of the horizontal sliding plate 520 close to the first mounting vertical plate 420, and the two groups of position sensors 310 are arranged on the mounting block 320. The mounting block 320 provides a stable platform for the two groups of position sensors 310, so that the position sensors 310 remain stable in the structure.

[0058] Please refer to Figure 2 and Figure 4 Further, the connecting piece 550 includes a third mounting vertical plate 551, a buffer connecting assembly 552, a lifting sliding block 553, a second sliding rail 554, and a connecting block 555. The third mounting vertical plate 551 is arranged on the lifting plate 540. One side of the lifting sliding block 553 is connected with the third mounting vertical plate 551 in the vertical direction through the second sliding rail 554. The upper end of the lifting sliding block 553 is connected with the third mounting vertical plate 551 through the buffer connecting piece 550. The connecting block 555 is arranged on the lifting sliding block 553, and the compression wheel 230 is rotatably arranged on the connecting block 555.

[0059] It should be noted that the lifting sliding block 553 is connected with the third mounting vertical plate 551 in the vertical direction through the second sliding rail 554, which enables the lifting sliding block 553 to move smoothly in the vertical direction. The upper end of the lifting sliding block 553 is connected with the third mounting vertical plate 551 through the buffer connecting piece 550. The design of the buffer connecting piece 550 aims to reduce the impact and vibration that may occur during the movement of the lifting sliding block 553, thereby protecting the mechanism and prolonging its service life. At the same time, the buffer connecting piece 550 can provide a certain buffer force when the compression wheel 230 contacts the roll core 100, making the compression process more stable and gentle. Even if there is a slight difference or unevenness between the compression wheel 230 and the roll core 100, the buffer connecting assembly 552 can absorb these differences through its buffering effect, thereby avoiding damaging the roll core 100.
