[0027] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0028] Example 1

[0029] like Figure 1-3 As shown, this embodiment discloses a material strip rewinding device, including a material supply tray 2 and a material receiving tray 1, wherein a positioning hole 11 and a limiting groove 12 are provided in the middle of the material supply tray 2 and the material receiving tray 1.

[0030] The device also includes a rotary drive mechanism, a driven rotary mechanism, a tension adjustment assembly and a guide assembly. The receiving tray 1 is arranged at the output end of the rotary drive mechanism, and the rotary drive mechanism is used to drive the receiving tray 1 to rotate. The driven rotary mechanism is arranged opposite to the rotary drive mechanism, and the supply tray 2 is arranged at the output end of the driven rotary mechanism, and the driven rotary mechanism is used to cooperate with the rotary drive mechanism to rewind the material belt 9 in the supply tray 2 from the supply tray 2 to the receiving tray 1. The tension adjustment assembly is arranged between the rotary drive mechanism and the driven rotary mechanism, and is used to adjust the tension of the material belt 9 when it is rewound between the rotary drive mechanism and the driven mechanism. The guide assembly is located between the rotary drive mechanism and the tension adjustment assembly, and is used to guide the path and direction of the material belt 9 in the supply tray 2 when it is rewound to the receiving tray 1.

[0031] The material strip rewinding device of this embodiment is driven by a driving component to rewind the material strip 9 in the supply tray 2 to the receiving tray 1 on the rotating drive mechanism. The material strip 9 can maintain a stable tension during the rewinding process through the tension adjustment component, thereby preventing the material strip 9 from being loosened or broken during the rewinding process. The guide component provides guidance for the material strip 9 during the rewinding process, so that the material strip 9 is rewound in a predetermined direction and path, thereby preventing the material strip 9 from being misaligned, entangled, stuck, etc. during the rewinding process. The material strip rewinding device of this embodiment is not only suitable for the rewinding of crystal oscillator material strips, but can also be used for the rewinding of other material strips.

[0032] The rotary drive mechanism includes a motor 31, the output end of the motor 31 is connected to a turntable drive shaft 35, the turntable drive shaft 35 is provided with a first limit plate 36 and a first fastener, the first fastener is detachably connected to the turntable drive shaft 35, the turntable drive shaft 35 is sleeved on the receiving tray 1 and movably connected to the receiving tray 1, and the receiving tray 1 is located between the first limit plate 36 and the first fastener. The first limit plate 36 is sleeved on the turntable drive shaft 35, and is used to fix the receiving tray 1 on the turntable drive shaft 38 with the first fastener. The first limit plate 36 is larger than the positioning hole 11 in the middle of the receiving tray 1, so that the first limit plate 36 can limit the receiving tray 1 on the turntable drive shaft 35.

[0033] like Figure 2As shown, in this example, the first fastener specifically includes a spring 32, a washer 33 and a nut 34. The end of the turntable drive shaft 35 is provided with a thread matching the nut 34. The spring 32 is located between the receiving tray 1 and the washer 33. The washer 33 is located between the spring 32 and the nut 34. The nut 34 is located at the end of the turntable drive shaft. The receiving tray 1 is fixed to the turntable drive shaft by the nut 34. The spring 32 is used to provide buffering and shock absorption for the receiving tray 1. The motor 31 may generate vibration and impact during operation. The spring 32 can effectively absorb these vibrations and impacts, so that the receiving tray 1 can run more stably on the turntable rotating shaft 35. In addition, the elastic force of the spring 32 makes the receiving tray 1 and the first limit plate 36 in close contact, preventing the turntable drive shaft 35 on the motor 31 from vibrating and causing the receiving tray 1 to loosen or shift. The washer 33 is disposed between the spring 32 and the nut 34 , and is mainly used to prevent the nut 34 from being over-tightened on the turntable drive shaft 35 and penetrating the spring 32 , thereby causing damage to the receiving tray 1 .

[0034] In some optional embodiments, the driven rotating mechanism includes a driven rotating shaft 41, on which a second limiting plate 43 and a positioning protrusion 42 are provided, a positioning hole 11 and a limiting groove 12 provided on the circumference of the positioning hole are provided in the middle of the feed tray 2, the driven rotating shaft passes through the positioning hole 11, and cooperates with the limiting groove 12 of the feed tray 2 through the positioning protrusion 42. The size of the second limiting plate 43 is larger than the positioning hole 11 in the middle of the feed tray 2, thereby effectively limiting the position of the feed tray 2 on the second limiting plate 43.

[0035] In order to make the feed tray 2 more firmly mounted on the driven rotating shaft 31, the driven rotating mechanism further includes a limiting assembly, and the feed tray 2 is arranged between the limiting assembly and the second limiting plate 43. The limiting assembly and the first limiting plate 43 cooperate to limit the feed tray 2 on the driven rotating shaft 42 to prevent the feed tray 2 from loosening or shifting when the driven rotating shaft 41 rotates.

[0036] In specific implementation, the first limiting plate 36 and the second limiting plate 43 can be implemented by limiting plates in the shape of a circle, a straight line or a cross, and the size of the positioning protrusion 42 matches the size of the limiting groove 12 on the feed tray 2, so that the positioning protrusion 42 can be firmly stuck in the limiting groove 12, thereby clamping the feed tray 2 on the driven rotating shaft, and then realizing that the driven rotating shaft drives the feed tray 2 to rotate simultaneously. The number of positioning protrusions 42 can be determined according to the number of limiting grooves 12 on the feed tray 2, and can be one or the same as the number of limiting grooves 12, so as to more firmly fix the feed tray 2 on the driven rotating shaft 31.

[0037] Specifically, the tension adjustment assembly includes a first roller 51 and a second roller 52, wherein the first roller 51 and the second roller 52 are arranged opposite to each other, and the second roller 52 is provided with a first groove 53 matching the material strip 9. When the first roller 51 and the second roller 52 are close to each other to a certain distance, a clamping station is formed so that the material strip 9 is kept in the clamping station for rewinding. The second roller 52 is used to support and guide the material strip 9, and the first roller 51 is used to provide tension for the material strip 9 so that the material strip 9 will not be deformed when passing through the conveying station formed by the first roller 51 and the second roller 52 during the rewinding process. The first roller 51 can be implemented by a tensioning wheel. By using a tensioning wheel to tension the material strip 9, the tension of the material strip 9 during the rewinding process can be more flexibly controlled.

[0038] The guide assembly includes a third roller 60, and a second groove 61 matching the material strip 9 is provided on the third roller 60. The third roller 60 is located on a side of the tension adjustment assembly close to the rotary drive mechanism. When the material strip 9 is rewound, it first passes through the tension adjustment assembly and then passes through the third roller 60. The second groove 61 of the third roller 60 and the first groove 53 of the second roller 52 are on the same horizontal plane. Through the second groove 61 on the third roller 60, the material strip 9 can be guided to rewind along a predetermined path, and the material strip 9 can be corrected from sliding, deflecting or slipping after passing through the tension adjustment assembly, thereby improving the accuracy and reliability of transmission during the rewinding process of the material strip 9.

[0039] The material tape rewinding device of this embodiment further includes a mounting assembly, and the rotary drive mechanism, the driven rotary mechanism, the tension adjustment assembly, and the guide assembly are all mounted on the mounting assembly. Specifically, the mounting assembly includes a first mounting plate 7 and a second mounting plate 8, the rotary drive mechanism is mounted on the second mounting plate 8, and the driven rotary mechanism is mounted on the first mounting plate 7. The tension adjustment assembly and the guide assembly can both be mounted on the first mounting plate, or both can be mounted on the second mounting plate, or the tension adjustment assembly can be mounted on the first mounting plate and the guide assembly can both be mounted on the first mounting plate.

[0040] The material strip rewinding device of this embodiment also includes a controller (not shown in the figure) and a sensor (not shown in the figure). The controller and the sensor are both electrically connected to the rotary drive mechanism. The sensor is used to sense whether the material strip 9 has been rewound, and the controller is used to control the start and stop of the rotary drive mechanism.

[0041] In the specific implementation process, the sensor is arranged between the rotary drive mechanism and the driven rotary mechanism, and is arranged on the rewinding path of the material belt 9 in the specific implementation, for real-time monitoring of the rewinding state of the material belt 9. When the material belt 9 starts to rewind, the sensor senses the position and movement of the material belt 9 in real time. Once the sensor detects that the material belt 9 has been completely rewound, that is, after detecting that there is no material belt rewinding on the rewinding path, the sensor sends a signal to the controller. After receiving the signal from the sensor, the controller controls the rotary drive mechanism to stop working, thereby ensuring that the material belt 9 does not continue to rewind after reaching the predetermined position.

[0042] In specific application, the positioning hole 11 in the middle of the supply tray 2 to be rewound is passed through the driven rotating shaft 41 and the limiting groove 12 on the positioning hole 11 passes through the positioning protrusion 42 on the driven rotating shaft 41, and then the supply tray 2 is fixed to the driven rotating shaft 41 through the firmware assembly, and part of the material belt 9 is released by manually rotating the driven rotating shaft 41 so that part of the material belt 9 is pre-rewound and fixed to the receiving tray 1 fixed on the driven rotating mechanism, and then the material belt 9 between the rotating drive mechanism and the driven rotating mechanism is placed on the first groove 53 of the first roller 52 of the tension adjustment assembly, and at the same time, the first roller 51 is rotated to clamp the material belt 9 on the clamping station formed by the second roller 52 and the first roller 51, and then the material belt 9 is placed on the second groove 61 of the third roller 60. When rewinding, start the motor 31 to start rewinding the material strip 9. When all the material strips 9 in the supply tray 2 are rewound onto the receiving tray 1, stop the motor 31, remove the receiving tray 1 and the supply tray 2, and complete the rewinding of the material strip 9.
