Description

Technical Field

[0001] The present application relates to the field of assembly equipment, and in particular to an assembly equipment for positioning sheets. Background Art

[0002] The positioning piece consists of a plastic shell part and a double-sided tape part. One side of the double-sided tape is adhered to the bottom of the plastic shell so that the two are combined to form a positioning piece.

[0003] When existing automated equipment processes positioning sheets, a whole roll of double-sided tape is laid on the table, and the plastic shells are transferred to the double-sided tape one by one through a vibrating plate and bonded to the double-sided tape. The double-sided tape is then cut with a cutter to make the size of the double-sided tape match the plastic shell.

[0004] Since the processing equipment in the existing technology only transfers the plastic shell to the double-sided tape, it cannot ensure the connection between the plastic shell and the double-sided tape. In addition, the cutter will apply a thrust along the transmission direction to the plastic shell during cutting, causing the plastic shell and the double-sided tape, which are originally unstable, to become misaligned or even separated, resulting in defective products. Utility Model Content

[0005] In order to solve the technical problem that the defective rate of positioning pieces processed by positioning piece processing equipment in the prior art is relatively high, the present application provides an assembly equipment for positioning pieces.

[0006] The present application provides a positioning piece assembly device, which adopts the following technical solution:

[0007] A positioning sheet assembly device includes a feeding mechanism, a driving source, a pressing mechanism and a cutting mechanism. The feeding mechanism is used to transport the plastic shell onto the double-sided tape. The pressing mechanism includes a pressing part, which is arranged on the output component of the driving source. The driving source is used to drive the pressing part to move in a direction perpendicular to the conveying direction of the plastic shell. The cutting mechanism is used to cut the double-sided tape. The pressing mechanism and the cutting mechanism are arranged along the conveying direction of the plastic shell.

[0008] By adopting the above technical solution, the plastic shell is pressed by the pressing mechanism before cutting the double-sided tape. Compared with simply transferring the plastic shell to the double-sided tape, the stability of the connection between the plastic shell and the double-sided tape is greatly improved, and the separation of the plastic shell and the double-sided tape due to cutting of the double-sided tape by the cutter can be avoided as much as possible, thereby improving the yield rate.

[0009] Optionally, the pressing member includes a pressing rod and a pressing head, the pressing rod is arranged on the output component of the driving source, the pressing head is arranged on the end of the pressing rod, the pressing head is elastic, and the pressing head is used to extrude and contact with the plastic shell.

[0010] By adopting the above technical solution, the plastic shell is pressed by the elastic pressing head, which avoids damage to the plastic shell as much as possible, and further improves the yield rate of the positioning piece.

[0011] Optionally, the pressing rod is slidably arranged on the output component of the driving source, and the pressing rod slides in a direction perpendicular to the conveying direction of the plastic shell. The pressing rod is connected to a damping spring for resetting the pressing rod.

[0012] By adopting the above technical solution, the plastic shell is pressed through the damping structure, which not only improves the stability of the connection between the plastic shell and the double-sided tape, but also the pressing part slides when pressing against the plastic shell, the spring deforms, and the plastic shell is gradually pressed with force instead of instantaneously impacting the plastic shell, thereby avoiding damage to the plastic shell as much as possible, and the pressing effect is better. The damping spring plays the role of pre-tightening and resetting.

[0013] Optionally, the pressing mechanism includes a damping seat and a rod sleeve, the damping seat is arranged on the output component of the driving source, the rod sleeve is arranged on the damping seat, the rod sleeve is provided with a large diameter hole and a small diameter hole connected to the large diameter hole, the small diameter hole is located on the side of the large diameter hole close to the pressing head, the pressing rod is slidably installed in the large diameter hole and the small diameter hole, and the pressing rod is provided with a limit member, and the cross-sectional size of the limit member is larger than the cross-sectional size of the small diameter hole.

[0014] By adopting the above technical solution, the rod sleeve is provided to guide the movement of the pressing rod, thereby reducing the overall thickness of the damping seat while ensuring a good guiding effect, saving material. The limiter is used to limit the pressing rod to prevent it from falling out of the damping seat due to gravity.

[0015] Optionally, the damping spring is sleeved on the pressing rod, and a limiting boss is provided on the pressing rod. One end of the damping spring abuts against the rod sleeve, and the other end of the damping spring abuts against the limiting boss.

[0016] By adopting the above technical solution, the damping spring sleeve is arranged on the pressing rod, which can play a certain guiding role in the sliding of the pressing rod. The damping spring is installed between the rod sleeve and the limiting boss. Compared with installing the damping spring between the rod sleeve and the pressing head, by setting a limiting boss with greater rigidity than the pressing head, it is helpful to install and compress the damping spring.

[0017] Optionally, the cutting mechanism is provided on an output component of the driving source, and the driving source is used to drive the cutting mechanism and the pressing mechanism to move synchronously.

[0018] By adopting the above technical solution, the pressing mechanism is installed on the output component of the driving source, and only one driving source is needed to achieve synchronous movement of the pressing mechanism and the cutting mechanism, saving energy and improving control stability and synchronization.

[0019] Optionally, the feeding mechanism includes a feeding seat, a cutting groove is provided on the feeding seat, and the cutting mechanism includes a cutting knife, and the cutting groove is for the cutting knife to extend into.

[0020] By adopting the above technical solution, the cutting knife extends into the cutting groove to cut the double-sided tape, which can ensure that the double-sided tape is completely cut off, reducing the possibility of affecting the yield rate due to incomplete cutting of the double-sided tape.

[0021] Optionally, the feeding mechanism includes a loading assembly, the loading assembly includes a loading drive source and a push rod, the push rod is provided with a receiving groove, the receiving groove is used to receive the plastic shell, and the side wall of the receiving groove is used to push the plastic shell.

[0023] Optionally, a plastic shell conveying groove is provided on the feeding seat, and the plastic shell conveying groove is used for laying double-sided tape.

[0024] By adopting the above technical solution, the plastic shell conveying groove can guide the movement of the double-sided tape and the plastic shell, preventing the plastic shell and the double-sided tape from moving away from the cutting position of the cutting mechanism.

[0025] Optionally, the feeding mechanism includes a double-sided tape feeding rack, and the double-sided tape feeding rack is provided with a plurality of groove wheels, and the groove wheels are used for winding the double-sided tape.

[0026] By adopting the above technical solution, the groove wheel can limit the distribution direction of the double-sided tape to prevent the double-sided tape from interfering with other structures.
