Description

Technical Field

[0001] This disclosure relates to the field of injection molding shell sprue removal technology, and in particular to an automatic headphone battery compartment shell removal and sprue removal device. Background Technology

[0002] An earphone battery compartment shell is injection molded. The sprue is located on the side wall of the shell, making it impossible to remove with punching tools or profile shears. The sprue must be manually removed after injection molding before packaging and shipping. However, manual sprue removal suffers from inconsistent force applied each time and by different employees, leading to dents and increased defect rates. Currently, a robotic arm removes the product and places it on the assembly line for manual sprue removal. Since only product removal is required, simple suction cups are used for clamping. Due to the complexity of the product and inconsistent orientation during in-mold removal, automated sprue removal requires precise product alignment and secondary positioning. Therefore, in addition to developing a sprue removal clamp, an automatic removal clamp needs to be designed to ensure consistent in-mold removal. Utility Model Content

[0003] In view of this, the present technical solution aims to propose an automatic removal and sprue opening device for the earphone battery compartment shell, which realizes the removal of the shell product and secondary positioning, and then the automatic sprue opening.

[0004] The technical solution of this utility model is an automatic headphone battery compartment shell removal and sprue removal device, which includes a shell suction mechanism, a shell positioning mechanism, and a sprue removal mechanism. The shell suction mechanism includes a first flat plate, a shell contouring suction nozzle disposed on the bottom surface of the first flat plate, and a sprue clamp. The top surface of the first flat plate is provided with a connecting seat for connecting an XYZ axis moving manipulator. The shell positioning mechanism includes a second flat plate and a positioning contouring block disposed on the second flat plate. The positioning contouring block is provided with a shell lower contouring groove and a long slot hole through which the shell sprue passes. The sprue removal mechanism includes a linear guide rail fixed to the bottom surface of the second flat plate, a slider disposed on the linear guide rail, a finger cylinder disposed at the bottom of the slider, and a driving component for driving the finger cylinder to move along the linear guide rail. The finger of the finger cylinder clamps the shell sprue inserted into the long slot hole, and the driving component drives the finger cylinder to move back and forth to remove the sprue.

[0005] Furthermore, the outer shell contouring nozzle includes a nozzle body, a contouring groove on the outer shell located at the bottom of the nozzle body, and a vacuum suction cup located at the bottom of the contouring groove on the outer shell. The nozzle body has an air passage communicating with the vacuum suction cup. An air pipe connector is connected to the upper end of the air passage of the nozzle body. The top surface of the nozzle body has a connecting rod that is connected to the first flat plate.

[0006] Furthermore, the connecting rod is a cylindrical optical rod, the lower end of which is fixedly connected to the nozzle body.

An annular groove is provided on the outer wall of the upper end of the cylindrical optical rod, and a retaining spring is installed in the annular groove for limiting the upper end of the cylindrical optical rod to the flange-type linear bearing.

[0007] Furthermore, the bottom of the first flat plate is arranged with two shell-shaped suction nozzles spaced apart side by side, forming a group. There are two groups, front and back, for a total of four shell-shaped suction nozzles. The first flat plate corresponding to the position between the two shell-shaped suction nozzles is provided with a second through hole. The second through hole is provided with the flow channel nozzle clamp, and the clamp opening of the flow channel nozzle clamp faces vertically downward.

[0008] Furthermore, the second flat plate includes four positioning contour blocks, which correspond to the positions of the four outer shell contour suction nozzles respectively. A third through hole is provided on the second flat plate at the position between two positioning contour blocks. The third through hole is used for inserting the flow channel nozzle clamp.

[0009] Furthermore, the linear guide rail includes two rails, which are arranged parallel to each other on the bottom of the second flat plate near the two sides. Two sliders are arranged front and rear on the same linear guide rail, and a connecting frame is provided between the two sliders. The driving component is fixed at the bottom of the second flat plate corresponding to the two linear guide rails. The driving component is connected to a crossbar, and the two ends of the crossbar are connected to the connecting frame.

[0010] Preferably, the driving component is a double-acting push rod cylinder or a servo motor.

It connects to the connecting seat on the shell suction mechanism of this device via an existing XYZ axis moving robot. This solution uses a vacuum suction cup to suction the injection-molded earphone battery compartment shell. While suctioning the shell, the shell-contouring suction nozzle simultaneously grips the sprue gate with a runner clamp. Then, the shell-contouring suction nozzle, sucked up by the shell-contouring block on the shell positioning mechanism, places the earphone battery compartment shell into the lower shell-contouring groove on the positioning block, achieving secondary positioning of the earphone battery compartment shell and the sprue gate. After positioning, a finger cylinder clamps the sprue gate, and then the sprue gate is removed by driving the finger cylinder to move back and forth. This device can automatically remove the earphone battery compartment shell and automatically remove the sprue gate, thus replacing manual removal of the sprue gate and greatly improving production efficiency.
