[0022] Figure 1 FIG. 1 is a schematic diagram of the three-dimensional structure of a carrier tape winding device 100 according to an embodiment of the present invention.

[0023] like Figure 1 As shown, the carrier tape winding device 100 may include a material discharge mechanism 11. The material discharge mechanism 11 may have a hopper 110 and a material blocking component 112, wherein the hopper 110 may be constructed to receive a plurality of empty material trays 102, and the material blocking component 112 may be constructed to allow the plurality of empty material trays 102 to exit the hopper 110 one by one.

[0024] The carrier tape winding device 100 may further include a material transfer mechanism 13. The material transfer mechanism 13 may include a material taking component 130 (see Figure 4 , 5 ) and displacement member 132 (see Figure 4, 5 ), wherein the picking component 130 is constructed to pick up the empty tray 102 withdrawn from the hopper 110, and the shifting component 132 is constructed to shift the picking component 130 between a plurality of stations.

[0025] The carrier tape winding device 100 may also include a winding mechanism 15. The winding mechanism 15 may have a positioning component 150, a guiding component 152, a detecting component 154, and a driving component 156. The positioning component 150 may be constructed to fix the empty material tray 102 collected by the material taking component 130 at the winding station. The guiding component 152 may be constructed to guide the carrier tape 104 to enter the bayonet (not shown) of the empty material tray 102. The detecting component 154 may be constructed to detect whether the carrier tape 104 enters the bayonet of the empty material tray 102. The driving component 156 may be constructed to drive the empty material tray 102 to rotate and wind the carrier tape 104 on the empty material tray 102.

[0026] The carrier tape winding device 100 may further include a recovery mechanism 17 configured to recover the fully wound material tray 102 after the material tray 102 is fully wound.

[0027] Figure 2 FIG. 1 is a schematic diagram of the three-dimensional structure of the unwinding mechanism 11 of the carrier tape winding device 100 according to an embodiment of the present invention during feeding. Figure 3 Shown is Figure 2 The side view of the discharge mechanism 11 during discharge is shown in FIG. Figure 2 , 3 The unloading mechanism 11 shown in FIG. 1 can be applied to include Figure 1 The carrier tape take-up device 100 shown includes several embodiments according to the present invention.

[0028] like Figure 2 , 3 As shown, the hopper 110 of the material discharging structure 11 has a bottom 111 and an inlet and outlet 113 opposite to the bottom 111. The hopper 110 of the material discharging structure 11 is designed to be flippable, for example, the flipping state can be controlled by setting a flip button (not shown) on the material discharging structure 11. The material blocking component 112 is telescopically arranged at the inlet and outlet 113 of the hopper 110. In this embodiment, the material blocking component 112 can be a plurality of cylinders, for example, it can be designed to be 3 cylinders.

[0029] In the feeding state, the inlet and outlet 113 is upward, and the blocking member 112 extends outside the inlet and outlet 113. In the discharging state, the inlet and outlet 113 is downward, and the blocking member 112 generally extends inside the inlet and outlet 113 to stop the material tray 102 from falling out of the hopper 110. It shrinks outside the inlet and outlet 113 only when an empty material tray 102 exits the inlet and outlet 113, and immediately returns to extend inside the inlet and outlet 113 after the material tray 102 exits. In this way, the discharge structure 11 can allow a plurality of empty material trays 102 to enter the hopper 110 in batches, and then exit the hopper 110 one by one.

[0030] Figure 4 FIG. 1 is a schematic diagram of the three-dimensional structure of the material transfer mechanism 13 of the carrier tape winding device 100 according to an embodiment of the present invention when taking materials from the material unwinding mechanism 11 . Figure 5 Shown is Figure 4 The three-dimensional structural schematic diagram of the material transfer mechanism 13 when moving the material tray 102 to the material winding mechanism 15. Figure 4 , 5 The material unwinding mechanism 11, material transfer mechanism 13 and material winding mechanism 15 shown in the figure can be applied to the following Figure 1 The carrier tape take-up device 100 shown includes several embodiments according to the present invention.

[0031] Combination Figure 4 , 5 As shown, the material taking component 130 of the material moving mechanism 13 can be a suction nozzle, for example, three suction nozzles in this embodiment. The shifting component 132 can include a material receiving and feeding cylinder 134, which is constructed to move the material taking component 130 to a corresponding one of the plurality of workstations.

[0032] The shifting component 132 may further include a stepper motor 136, which is constructed to adjust the material taking component 130 and the receiving and feeding cylinder 134 to a desired position state before the material taking component 130 is shifted between a plurality of stations. For example, when taking materials, the stepper motor 136 modulates the receiving and feeding cylinder 134 and the material taking component 130 to a first position state, and the receiving and feeding cylinder 134 moves the material taking component 130 to the material taking station to receive the empty material tray 102 withdrawn from the hopper 110. When feeding materials, the stepper motor 136 adjusts the receiving and feeding cylinder 134 and the material taking component 130 to a second position state, and the receiving and feeding cylinder 134 moves the material taking component 130 to the feeding station to move the empty material tray 102 to the driving component 156 of the coiling mechanism 15. When recycling materials, the stepper motor 136 adjusts the feeding and receiving cylinder 134 and the material picking component 130 to the second position state, and the feeding and receiving cylinder 134 moves the material picking component 130 to the feeding station to collect the fully rolled material tray 102 and moves it to the recycling station to be recycled by the recycling component 17.

[0033] Specifically, in the standby state, the material taking component 130 and the material receiving and feeding cylinder 134 can be in a first position state, such as a vertical position state. The material taking component 130 can be on the standby position and set to face downward. When it is necessary to take materials from the material discharging mechanism 11, the stepper motor 136 adjusts the material taking component 130 and the material receiving and feeding cylinder 134 to the material taking position state, for example, the material taking component 130 is turned upside down, and the material receiving and feeding cylinder 134 moves the material taking component 130 to the material taking position to collect the empty material tray 102 withdrawn from the hopper 110. In order to cooperate with the design of the material taking component 130, the material tray 102 can be set to be loaded into the hopper 110 with the vacuum surface 103 downward. When the feeding cylinder 134 moves the material taking component 130 to the bottom of the material inlet and outlet 113 of the hopper 110, that is, when it reaches the material taking station, the material blocking component 112 withdraws from the hopper 110, thereby allowing the material tray 102 to escape from the hopper 110. The material taking component 130 can firmly suck the vacuum surface 103 of the escaped material tray 102, and then the material receiving and feeding cylinder 134 resets the material taking component 130 and brings it back to the material taking station. After a piece of material tray 102 escapes, the material blocking component 112 immediately resets and continues to stop the material tray 102 in the hopper 110.

[0034] After picking up the material, the stepper motor 136 can rotate the picking component 130 and the receiving and feeding cylinder 134 to another position, such as a horizontal position. The picking component 130 is pushed out to the feeding station by the receiving and feeding cylinder 134 to move the adsorbed material tray 102 to the driving component 156 of the coiling mechanism 15.

[0035] According to other embodiments of the present invention, in the standby state, the material taking component 130 and the material receiving and feeding cylinder 134 can be in the second position state or other position state, and only need to be adjusted before entering the desired position state. At the same time, according to the embodiment of the present invention, the material moving mechanism 13 can be further constructed to move the material tray 102 with the full belt 104 to the recovery mechanism 17, such as Figure 7 As shown, detailed description will be given later.

[0036] Figure 6 FIG. 1 is a schematic diagram of the three-dimensional structure of the winding mechanism 15 of the carrier tape winding device 100 according to an embodiment of the present invention. Figure 6 The coiling mechanism 15 shown in FIG. 1 can be applied to Figure 1 The carrier tape take-up device 100 shown includes several embodiments according to the present invention.

[0037] like Figure 6 As shown, the positioning component 150 and the guiding component 152 of the coiling mechanism 15 can both be cylinders. The guiding component 152 can be constructed to be located on opposite sides of the carrier tape 104 during the process of the carrier tape 104 entering the latch of the material tray 102. The detection component 154 can be a sensor driven by the cylinder. The driving component 156 can be a driving motor.

[0038] After the material transfer mechanism 13 delivers the obtained empty tray 102 to the torque motor shaft of the driving component 156, that is, after the tray 102 is in place, the positioning component 150, such as a positioning cylinder, can be extended to block the tray 102 to fix it. The guiding component 152, such as the upper and lower guiding cylinders, moves to a horizontal position. Driven by the machine motor (not shown), the carrier 104 is guided by the upper and lower guiding cylinders through the flow channel (not shown) to enter the bayonet of the tray 102. The detection component 154, such as a material detection sensor, can be driven by the extended detection cylinder and sent to the detection station. After the detection component 154 detects that the carrier 104 enters the bayonet of the tray 102, that is, enters the correct working position, the detection cylinder drives the material detection sensor to reset. Similarly, after confirming that the detection component 154 detects that the carrier 104 enters the tray 102, the positioning component 150 and the guiding component 152 are reset. Thereafter, the driving component 156 , such as a driving motor, can drive the material tray 102 to rotate and enter a normal state of winding up the carrier tape 104 .

[0039] Figure 7 FIG. 1 is a schematic diagram of the three-dimensional structure of the material transfer mechanism 13 and the recovery mechanism 17 of the carrier tape winding device 100 according to an embodiment of the present invention when the material transfer mechanism 13 is located at the material receiving station. Figure 7 The recovery mechanism 17 shown in FIG. 1 can be applied to include Figure 1 The carrier tape take-up device 100 shown includes several embodiments according to the present invention.

[0040] like Figure 7 As shown, the recovery mechanism 17 may have a material receiving rod 170, which is constructed so that the fully rolled material trays 102 are arranged in sequence along the material receiving rod 170. The recovery mechanism 17 may further include a material moving component 172, and the material receiving rod 170 may be disposed on the material moving component 172. The material moving component 172 may be constructed to move the material receiving rod 170 away after the material trays 102 on the material receiving rod 170 are fully arranged.

[0041] Specifically, according to an embodiment of the present invention, when the material tray 102 is fully rolled, the feeding and receiving cylinder 134 extends and moves the material picking component 130 to the fully rolled material tray 102. After the material picking component 130 sucks the material tray 102, the feeding and receiving cylinder 134 resets. Then the stepper motor 136 drives the material picking component 130 to rotate a certain angle, preferably, the angle is equal to the inclination of the receiving rod 170, so that the material picking component 130 is aligned with the receiving rod 170. Then the feeding and receiving cylinder 134 controls the feeding and receiving cylinder 134 to collect the material tray 102 to the receiving rod 170. For example, when the material picking component 130 is a suction nozzle, the suction nozzle can release the material tray 102, and the material tray 102 slides down along the receiving rod 170 and is arranged in sequence. Thereafter, the feeding and receiving cylinder 134 resets, the stepper motor 136 returns to the initial position, and enters the next winding material working cycle. After the material trays 102 are fully loaded on the material receiving rod 170 , the material moving component 172 can be pulled to remove the material receiving rod 170 , so that the fully rolled material trays 102 can be moved out and removed.

[0042] The carrier tape winding device 100 provided in the embodiment of the present invention is an automatic tray replacement system, which can place a plurality of empty trays 102 at a time, and when the tray 102 is full, it can automatically replace the empty tray 102, and stably place the tray 102 full of carrier tape 104 at a designated position. Accordingly, the present invention can reduce the waiting time of the machine downtime and reduce the work intensity of the operator, thereby achieving the purpose of saving manpower and improving production efficiency.

[0043] Moreover, the carrier tape winding device 100 provided in the embodiment of the present invention is an independent structure and can be applied to various types of sorting machines. In addition, the carrier tape winding device 100 provided in the embodiment of the present invention is mainly composed of an electrical control system and a mechanical operating system, and can achieve communication with the machine by sharing only two input and output ports of the machine, and can be effectively compatible with the original machine.
