[0037] The embodiments of the present application disclose a track type conveying mechanism for FPC packaging.

[0038] A track type conveying mechanism for FPC packaging, FPC refers to flexible circuit board, the application provides stable conveying in the flexible circuit board packaging process.

[0039] Reference Figure 1 As shown, including track assembly 1, clamping assembly 2 and drive assembly 3, track assembly 1 includes two parallel arrangement of limiting rail 11, limiting groove 111 is opened in the inner side of limiting rail 11, flexible circuit board is located in limiting groove 111, flexible circuit board can be inserted into limiting groove 111, limiting groove 111 provides limiting action, so that the flexible circuit board can't get out of limiting groove 111, to ensure the accuracy of conveying path.

[0040] Clamping assembly 2 is connected with track assembly 1, track assembly 1 and clamping assembly 2 cooperate with each other, which can realize the limiting and stable transmission of flexible circuit board.

[0041] Drive assembly 3 includes servo motor 31 and synchronous transmission component 32, servo motor 31 provides driving force for synchronous transmission component 32, flexible circuit board is laid on the surface of synchronous transmission component 32, synchronous transmission component 32 is located in limiting groove 111, so that synchronous transmission component 32 can convey flexible circuit board.

[0042] Specifically, the flexible circuit board is inserted into the limiting groove 111, which limits the movement path of the flexible circuit board, avoids deviation, and achieves the effect of accurate conveying. Under the driving action of the servo motor 31, the synchronous transmission component 32 provides accurate and stable power output for the flexible circuit board, and cooperates with the clamping action provided by the clamping assembly 2 to ensure that the flexible circuit board can move smoothly in the limiting rail 11, thereby significantly improving the transmission efficiency and accuracy.

[0043] Further, the limiting rail 11 is an aluminum alloy rail. The aluminum alloy rail has good wear resistance and corrosion resistance, and has high structural strength, so it can withstand the weight of the flexible circuit board for a long time.

[0044] In some embodiments, as shown in Figure 1 and Figure 2 As shown, clamping assembly 2 includes circulating fan 21, air pressure part 22 and adsorption part 23; air pressure part 22 is installed above limiting rail 11 and communicates with limiting groove 111, air pressure part 22 can adopt air pressure cylinder or air pressure pipe, air pressure part 22 communicates with the upper surface of limiting groove 111, so that air pressure part 22 blows from top to bottom in vertical direction when providing air pressure, without rigid contact, to ensure the safety of flexible circuit board conveying, and the air pressure makes the flexible circuit board more easily adhere to the synchronous transmission component 32, ensuring the stability of transmission.

[0045] The suction part 23 is located below the limiting track 11 and extends towards the interval of the synchronous transmission part 32, and is vertically directed towards the flexible circuit board opening. The suction part 23 can adopt a suction cylinder or a suction pipe. The suction part 23 can generate negative pressure to provide suction force from below the limiting track 11, so that the flexible circuit board is adsorbed on the synchronous transmission part 32 under the action of negative pressure, and cooperates with the wind pressure part 22 to make the flexible circuit board be clamped by the airflow in two directions of up and down.

[0046] One end of the circulating fan 21 is connected with the wind pressure part 22, and the other end is connected with the suction part 23. The circulating fan 21 draws air into the suction part 23 and delivers it to the wind pressure part 22 to realize air circulation.

[0047] The circulating fan 21 is connected with the wind pressure part 22 and the suction part 23 through a pipeline.

[0048] Specifically, after the circulating fan 21 provides negative pressure from the suction part 23, the airflow is transmitted from the suction part 23 to the wind pressure part 22 through the circulating fan 21, and the airflow is discharged from the flexible circuit board by the wind pressure part 22, so that the flexible circuit board is clamped on the synchronous transmission part 32 by the airflow, ensuring stable conveying of the flexible circuit board and preventing deviation.

[0049] Further, as shown in Figure 2 The wind pressure part 22 is spaced apart by a predetermined distance and is connected with the limiting groove 111 through the wind pressure port 221. The wind pressure port 221 can be composed of multiple circular ports. When multiple circular ports are used, a set of wind pressure ports 221 can be arranged at a predetermined distance, so that the flexible circuit board can be blown by the airflow of the wind pressure port 221 when conveying a predetermined distance, and the flexible circuit board is moved by the downward pressure of the wind force.

[0050] In addition to the multiple circular ports, the wind pressure port 221 can also adopt a linear slit. The linear slit is linearly arranged along the extension direction of the limiting groove 111. This way can make the airflow evenly blow the flexible circuit board from the linear slit, so that the flexible circuit board can get more uniform airflow. The above two kinds of wind pressure ports 221 can be used, and the user can choose according to the needs.

[0051] Specifically, the airflow is dispersed into the limiting groove 111 by the wind pressure port 221, so that the flexible circuit board can be blown by the dispersed wind force, and the effect of being blown by the wind force can be ensured during the movement with the synchronous transmission part 32.

[0052] The wind pressure part 22 can be provided with a liftable closing part. The closing part can adopt a closing pipe or a closing rod. The closing part is in close contact with the wind pressure port 221, and the closing pipe or the closing rod extends along the length direction of the wind pressure part, so that all the wind pressure ports 221 can be closed at the same time.

[0053] The air cylinder can be arranged in the air pressure port 221 in a liftable manner to drive the closing part, or a pivotally connected screw rod is arranged on the closing part, a threaded hole is arranged on the air pressure part 22, the screw rod is screwed with the threaded hole and extends out of the air pressure part 22, and rotating the screw rod outside the air pressure part 22 can make the closing part lift in the air pressure part 22, and the closing part changes the adhesion to the air pressure port 221 at the same time of lifting. When the closing part is close to the air pressure port 221, the closing part gradually blocks the air pressure port 221 to reduce the air volume of the air pressure port 221. When the closing part is away from the air pressure port 221, the closing part opens the air pressure port 221 to increase the air volume of the air pressure port 221. The closing part lifting can realize the function of adjusting the air volume.

[0054] Further, as shown in Figure 1 The adsorption part 23 is divided into a plurality of adsorption ports 231. When the adsorption part 23 is an adsorption cylinder or an adsorption pipe, the adsorption part 23 is arranged along the length direction of the limiting track 11, so that a distance between the adsorption ports 231 is pre-set, the adsorption effect is more uniform, and the adsorption effect is obtained at a pre-set distance along the length direction of the limiting track 11.

[0055] The adsorption part 23 is located in the middle of the width direction of the limiting track 11, so that the middle of the flexible circuit board is subjected to the adsorption effect of the adsorption part 23, and the two sides in the limiting groove 111 are subjected to the air pressure effect, and the two effects are matched to provide clamping.

[0056] In some embodiments, as shown in Figure 1 and Figure 2 The synchronous transmission part 32 includes a rotating roller 321, a gear 322 and a transmission chain 323. The rotating roller 321 is provided with a plurality of rotating rollers 321, which are arranged in the limiting groove 111 at a pre-set distance and are pivotally connected to the inner wall of the limiting track 11. A pivot slot or a pivot hole can be arranged at the groove wall of the limiting groove 111, and the two ends of the rotating roller 321 are respectively inserted into the pivot slots or pivot holes of the two limiting tracks 11, so that the rotating roller 321 can rotate along the pivot slot or the pivot hole.

[0057] The rotating rollers 321 are arranged at a pre-set distance, so that there is a gap between the adjacent rotating rollers 321, and the gap is the opening and adsorption position of the adsorption port 231.

[0058] As shown in Figure 3 Each rotating roller 321 is provided with a set of gears 322, and the number of gears 322 in the set is two. A set of transmission chains 323 is conveniently sleeved on the two adjacent gears 322 on the two sides, the gears 322 are engaged with the transmission chains 323 to provide driving, so that the multiple sets of transmission chains 323 are sequentially rotated to drive the rotating roller 321 to rotate. Any rotating roller 321 is connected with the driving end of the servo motor 31, so that the driving force of the servo motor 31 can be transmitted to the connected rotating roller 321.

[0059] Specifically, the servo motor 31 drives the rotation roller 321 connected therewith to rotate, the rotation roller 321 drives the gear 322 to rotate, the transmission chain 323 is sleeved on the gear 322, so that all the rotation rollers 321 are driven to rotate, the flexible circuit board is laid on the surfaces of the rotation rollers 321, and the rotation rollers 321 drive the flexible circuit board to convey along the surfaces of the rotation rollers 321 when rotating.

[0060] Wherein, a rubber conveying belt can be laid on the surface of the rotation roller 321, and the conveying effect can also be achieved, and the transmission mode can be determined according to the requirement.

[0061] Further, referring to FIG. 4, Figure 2 As shown, the limiting groove 111 is provided with a partition plate 324, the partition plate 324 separates the gear 322 and the flexible circuit board, the partition plate 324 can separate the gear 322 and the flexible circuit board, so that the flexible circuit board will not contact the gear 322 when the gear 322 rotates, and the safety in the conveying process is ensured.

[0062] Further, referring to FIG. 5, Figure 2 As shown, the limiting groove 111 is a T-shaped groove, and the T-shaped groove is arranged to be turned by 45°, and the turned T-shaped groove can adapt the gear 322 in the T-shaped groove, and provide certain adaptability.
