It should be noted that, for the convenience of description, only the part related to the utility model is shown in the drawing. In the case of no conflict, the embodiment in the utility model and the features in the embodiment can be combined with each other.

[0054] Combined Figures 1-10The utility model discloses a carrier tape take-up auxiliary mechanism for controlling the rotating speed of material take-up wheel 310, and further controlling the take-up speed of material 400, material take-up wheel 310 is driven by material take-up motor 300, and material take-up motor 300 is controlled the rotating speed by controller, and the carrier tape take-up auxiliary mechanism includes installation component 100, tensioning part 120 and detection component, installation component 100 is rotatably provided with swing arm 110, tensioning part 120 is arranged at the first end of swing arm 110 and is used for tensioning material 400, material take-up wheel 310 can be arranged on installation component 100, and carrier tape and other belt-shaped materials 400 are wound on material take-up wheel 310, along with the rotation of material take-up motor 300, material 400 is wound up or gradually unwound by material take-up wheel 310, material take-up wheel 310 and tensioning part 120 are arranged at intervals, and the winding plane of material take-up wheel 310 to material 400 and the tensioning plane of tensioning part 120 to material 400 are the same plane to avoid the torsion of material 400 in the winding or unwinding process.

[0055] Detection component includes first detection piece 200 and detected piece 220, and first detection piece 200 is arranged on installation component 100, and detected piece 220 is connected with swing arm 110 and follows swing arm 110, and controller is used for accepting the detection signal of first detection piece 200, wherein when swing arm 110 rotates to first position along first direction, detected piece 220 follows swing arm 110 to the detection position of first detection piece 200 to trigger first detection piece 200, so that first detection piece 200 can send first signal to controller, and the rotating speed of material take-up wheel 310 is controlled by controller.

[0056] Compared with prior art, the utility model tightens material 400 through tensioning part 120, when material take-up wheel 310 is unwinding wheel, if the unwinding speed of material take-up wheel 310 and the take-up speed of downstream transmission belt do not match, or when material take-up wheel 310 is winding wheel, if the winding speed of material take-up wheel 310 and the take-up speed of upstream transmission belt do not match, all make material 400 on tensioning part 120 force swing arm 110 to move along first direction, and further can judge the current take-up speed of material 400 through the position of detected piece 220 detected by first detection piece 200 to regulate and control the rotating speed of material take-up wheel 310, when the take-up speed gradually matches, swing arm 110 starts to recover along the opposite direction under the action of its gravity, thereby reducing the influence of the change of winding diameter in the take-up process, realizing timely take-up, and the structure is simple and compact, and operation is reliable.

[0057] Further optimization scheme, the detection assembly further comprises a second detection member 210, the second detection member 210 is arranged on the mounting assembly 100 and follows the swing arm 110, and the controller is used for accepting the detection signal of the second detection member 210. Wherein, when the swing arm 110 rotates to the first position along the first direction, only the first detection member 200 is triggered, and the first detection member 200 is used to send a first signal to the controller, so that the controller controls the rotation speed of the material loading and unloading wheel 310 to increase (it can be increased from stopping loading and unloading to preset speed for loading and unloading); when the swing arm 110 gradually recovers under the action of its own gravity, the swing arm 110 rotates to the second position along the second direction opposite to the first direction, the detection member 220 follows the swing arm 110 to the detection position of the second detection member 210, so as to trigger the second detection member 210, at this time the first detection member 200 is not triggered, and the second detection member 210 sends a second signal to the controller, so that the controller controls the rotation speed of the material loading and unloading wheel 310 to decrease (it can be decreased from the preset speed to stop loading and unloading).

[0058] For convenience of description, the following is described with the rotation speed ratio of the material loading and unloading wheel 310 to the material loading and unloading motor 300 being 1:1, but the rotation speed ratio of the material loading and unloading wheel 310 and the material loading and unloading motor 300 of the utility model is not limited to 1:1.

[0059] Exemplarily, when the carrier tape loading and unloading auxiliary mechanism is used to assist the unloading mechanism to unload, with the rotation of the material loading and unloading motor 300, the material 400 is gradually unloaded by the material loading and unloading wheel 310 and is subjected to subsequent processes at the downstream mechanism, the tensioning member 120 tensions the material 400 between the material loading and unloading wheel 310 and the downstream mechanism, and the swing arm 110 is used to control the rotation speed of the material loading and unloading motor 300. Figure 10, according to the different material 400 discharge amount, the tensioning component 120 is supported by the material 400 in different positions, and drives the swing arm 110 to rotate, so that the detected piece 220 can trigger the first detection piece 200 and the second detection piece 210 respectively. In order to facilitate the description, it is defined that when the tensioning component 120 is not set, the extension length of the material 400 from the material winding and unwinding wheel 310 to the downstream mechanism is the first initial length, when the tensioning component 120 is set and the first detection piece 200 is triggered, the extension length of the material 400 from the material winding and unwinding wheel 310 to the downstream mechanism is the first tensioning length, and when the tensioning component 120 is set and the second detection piece 210 is triggered, the extension length of the material 400 from the material winding and unwinding wheel 310 to the downstream mechanism is the second tensioning length, then the first tensioning length is less than the second tensioning length and greater than the first initial length. When the first detection piece 200 is triggered, it indicates that the material 400 discharged by the current material winding and unwinding wheel 310 is less, at this time the speed of the material winding and unwinding motor 300 needs to be increased to ensure the continuous supply of the material 400; when the second detection piece 210 is triggered, it indicates that the material 400 discharged by the current material winding and unwinding wheel 310 is more, at this time the speed of the material winding and unwinding motor 300 can be reduced to ensure the appropriate supply of the material 400.

[0060] When the take-up and pay-off auxiliary mechanism is used to assist the take-up mechanism to take up the material, as the material take-up and pay-off motor 300 rotates, the material 400 conveyed by the upstream mechanism is gradually wound and collected by the material take-up and pay-off wheel 310, and the tensioning component 120 tensions the material 400 between the material take-up and pay-off wheel 310 and the upstream mechanism. According to the amount of the material 400 conveyed by the upstream mechanism and the winding speed of the material 400 by the material take-up and pay-off wheel 310, the tensioning component 120 is supported at different positions by the material 400, and drives the swing arm 110 to rotate, so that the detection member 220 can trigger the first detection member 200 and the second detection member 210, respectively. It is defined that when the tensioning component 120 is not provided, the extension length of the material 400 from the upstream mechanism to the material take-up and pay-off wheel 310 is a second initial length, when the tensioning component 120 is provided and the first detection member 200 is triggered, the extension length of the material 400 from the upstream mechanism to the tensioning component 120 and then to the material take-up and pay-off wheel 310 is a third tensioning length, and when the tensioning component 120 is provided and the second detection member 210 is triggered, the extension length of the material 400 from the upstream mechanism to the tensioning component 120 and then to the material take-up and pay-off wheel 310 is a fourth tensioning length. The third tensioning length is smaller than the fourth tensioning length and greater than the second initial length. When the first detection member 200 is triggered, it indicates that the current winding speed of the material take-up and pay-off wheel 310 is too fast, and the amount of the material 400 conveyed by the upstream mechanism cannot meet the continuous winding of the material take-up and pay-off wheel 310 at the current speed, so the speed of the material take-up and pay-off motor 300 needs to be reduced. When the second detection member 210 is triggered, it indicates that the current winding speed of the material take-up and pay-off wheel 310 is too slow, so the speed of the material take-up and pay-off motor 300 needs to be increased.

[0061] As can be understood by those skilled in the art, the specific value of the speed of the material take-up and pay-off wheel 310 controlled by the controller to increase or decrease can be set according to actual conditions, or in some embodiments, the controller can also control the speed of the material take-up and pay-off wheel 310 to increase or decrease to a certain preset speed. Specifically, when the swing arm 110 rotates to the first position along the first direction, the first detection member 200 is used to send a first signal to the controller, so that the controller controls the material take-up and pay-off wheel 310 to rotate at a first preset speed. When the swing arm 110 rotates to the second position along the second direction, the second detection member 210 is used to send a second signal to the controller, so that the controller controls the material take-up and pay-off wheel 310 to rotate at a second preset speed. The first preset speed is greater than the second preset speed, and the second preset speed is greater than or equal to zero. When the second preset speed is zero, it indicates that when the second detection member 210 is triggered, the material take-up and pay-off motor 300 directly stops, and when the first detection member 200 is triggered, the material take-up and pay-off motor 300 is restarted and rotates at the first preset speed to pay off or wind the material 400.

[0062] In an embodiment, the detected piece 220 comprises an integrated trigger part connected with the swing arm 110 and used to follow the swing arm 110 to the detection position of the first detection piece 200 and the detection position of the second detection piece 210, that is, the integrated trigger part can trigger the first detection piece 200 and the second detection piece 210 respectively.

[0063] In another embodiment, in combination with Figure 9 the detected piece 220 comprises a first trigger part 221 and a second trigger part 222, both of which are connected with the swing arm 110 and follow the swing arm 110, and the first trigger part 221 and the second trigger part 222 are arranged at an angle to facilitate the layout of the first detection piece 200 and the second detection piece 210. Wherein, when the swing arm 110 rotates to the first position along the first direction, the first trigger part 221 follows the swing arm 110 to the detection position of the first detection piece 200, and the second trigger part 222 follows the swing arm 110 to the avoidance position, the first detection piece 200 is used to send a first signal to the controller to make the controller control the speed of the material collecting and releasing wheel 310 to increase; when the swing arm 110 rotates to the second position along the second direction, the second trigger part 222 follows the swing arm 110 to the detection position of the second detection piece 210, and the first trigger part 221 follows the swing arm 110 to the avoidance position, the second detection piece 210 is used to send a second signal to the controller to make the controller control the speed of the material collecting and releasing wheel 310 to decrease, the second direction is opposite to the first direction, and the avoidance position refers to the position avoiding the detection position of the first detection piece 200 and the detection position of the second detection piece 210, that is, the first trigger part 221 and the second trigger part 222 can trigger the first detection piece 200 and the second detection piece 210 respectively and do not interfere with each other.

[0064] The first trigger part 221 and the second trigger part 222 described above can be a split structure or an integrated structure.

[0065] The specific types of the first detection piece 200 and the second detection piece 210 are not limited, in an embodiment, the first detection piece 200 and the second detection piece 210 are both reflective sensors. Correspondingly, the first trigger part 221 and the second trigger part 222 are both plate-shaped and can be rotated into the detection holes of the first detection piece 200 and the second detection piece 210 to trigger the first detection piece 200 and the second detection piece 210 respectively.

[0066] In a specific embodiment disclosed in the utility model, the carrier tape collecting and releasing auxiliary mechanism further comprises a limiting assembly, the limiting assembly comprises a first limiting piece 140 and a second limiting piece 141, in combination with Figure 6The first limiting member 140 and the second limiting member 141 are arranged on the mounting assembly 100; when the swing arm 110 continues to rotate after passing the first position in the first direction, the swing arm 110 is limited and cannot continue to rotate until the first limiting member 140 abuts against the swing arm 110; when the swing arm 110 continues to rotate after passing the second position in the second direction, the swing arm 110 cannot continue to rotate until the second limiting member 141 abuts against the swing arm 110. The swing angle of the swing arm 110 can be limited by the arrangement of the first limiting member 140 and the second limiting member 141.

[0067] To facilitate the adjustment of the swing angle of the swing arm 110 and the adjustment of the tensioning degree of the tensioning component 120 on the material 400, in combination with Figure 7 The first sliding groove 150 and the second sliding groove 151 are arranged on the mounting assembly 100, the first limiting member 140 is arranged in the first sliding groove 150 in a position adjustable manner, and the second limiting member 141 is arranged in the second sliding groove 151 in a position adjustable manner. For example, the first limiting member 140 and the second limiting member 141 can be bolts, which are screwed on the first sliding groove 150 and the second sliding groove 151 by nuts.

[0068] Further, the second end of the swing arm 110 is provided with a counterweight component 130, and the tensioning component 120 and the counterweight component 130 are arranged on the two sides of the rotation fulcrum of the swing arm 110. For example, Figure 7 The technical scheme of tensioning the material 400 by the gravity of the tensioning component 120 is shown in the embodiment, and the counterweight component 130 is used to balance the gravity of the tensioning component 120 and adjust the tensioning force of the tensioning component 120 on the material 400.

[0069] In an embodiment, in combination with Figure 8 The second end of the swing arm 110 is provided with an elastic member 131, one end of the elastic member 131 is connected with the swing arm 110, and the other end is connected with the mounting assembly 100. The elastic member 131 is used to balance the gravity of the tensioning component 120 and adjust the tensioning force of the tensioning component 120 on the material 400.

[0070] To facilitate the movement of the material 400 around the tensioning component 120, the tensioning component 120 has a curved surface that is in sliding cooperation with the material 400.
