Description

Technical Field

[0001] The present invention relates to the field of film laminating equipment, and particularly to a film laminating equipment for the shell of a wireless charger. Background Art

[0002] With the continuous improvement of the requirements of electrical equipment for power supply quality, safety, reliability, convenience, instantaneity, special occasions, special geographical environments, etc., the contact power transmission method is increasingly unable to meet the actual needs.

[0003] A wireless charger is a device that charges using the principle of electromagnetic induction. Its principle is similar to that of a transformer. By arranging a coil at each of the transmitting and receiving ends, the transmitting-end coil emits an electromagnetic signal to the outside under the action of electricity, and the receiving-end coil receives the electromagnetic signal and converts the electromagnetic signal into an electric current, thereby achieving the purpose of wireless charging. Wireless charging technology is a special power supply method. It does not require a power cord, relies on the propagation of electromagnetic waves, and then converts the electromagnetic wave energy into electrical energy to finally achieve wireless charging.

[0004] However, during the manufacturing process of wireless charger products, defects such as scratches and scrapes will appear on the product surface, and these surface defects will affect the product quality inspection standards. The current solution is to add a protective film on the product surface to achieve the effect of protection against scratching. In the prior art, the film laminating for the shell of a wireless charger is generally carried out by manual film laminating. Manual film laminating not only increases the working intensity of the staff, has low work efficiency, but also may cause the film to be incorrectly positioned due to human factors, and the film needs to be peeled off and reattached, resulting in a slower production efficiency and a further increase in the labor intensity of the staff. Manual film laminating takes a lot of time and has a series of problems such as inaccurate film laminating, slow speed, long time consumption, high cost, and low efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a film laminating equipment for the shell of a wireless charger with high automation and high efficiency, which can at least solve one of the above problems.

[0006] According to one aspect of the present invention, there is provided a film laminating equipment for the shell of a wireless charger, including a machine table and a feeding device, a first film laminating device, a material transferring device, a second film laminating device, and a discharging device arranged on the machine table;

[0007] The feeding device is configured to convey the workpiece to be film laminated to the first film laminating device;

[0008] The first film laminating device is configured to laminate the side surface of the workpiece to be film laminated;

[0011] The blanking device is arranged at the discharge end of the second film pasting device and is configured to output the workpiece after film pasting.

[0012] Thus, the working principle of the wireless charger housing film pasting equipment of the present invention is as follows: The feeding device automatically conveys the workpiece to be film pasted to the first film pasting device. The first film pasting device pastes a film on the side surface of the workpiece to be film pasted. The material transfer device automatically conveys the workpiece after being pasted with a film by the first film pasting device to the second film pasting device. The second film pasting device pastes films on both the front and back sides of the workpiece conveyed by the material transfer device. The blanking device automatically outputs the workpiece after film pasting. The film pasting equipment of the present invention can perform full-automatic film pasting on the wireless charger housing, with accurate positioning, high efficiency, good film pasting effect, small error, capable of reducing the input of personnel and lowering the labor cost.

[0013] In some embodiments, the first film pasting device includes a first rotary positioning fixture, a first driving module, a side film pasting mechanism, and a second driving module. The first rotary positioning fixture is installed on the first driving module, the side film pasting mechanism is installed on the second driving module, the first driving module and the second driving module are installed on the machine table. The first driving module is used to drive the first rotary positioning fixture to feed along the X-axis direction, and the second driving module is used to drive the side film pasting mechanism to feed along the Y-axis direction. The first rotary positioning fixture is used to place the workpiece to be film pasted and cooperate with the side film pasting mechanism to jointly complete side film pasting. Thus, the working principle of the first film pasting device is as follows: The feeding device automatically conveys the workpiece to be film pasted to the first rotary positioning fixture. The first rotary positioning fixture rotates and positions. The second driving module drives the side film pasting mechanism to feed along the Y-axis direction. While the first rotary positioning fixture rotates the workpiece to be film pasted, the first driving module drives the first rotary positioning fixture to feed along the X-axis direction, and cooperates with the side film pasting mechanism to jointly complete the side film pasting work.

[0014] In some embodiments, the side film pasting mechanism includes a mounting plate and a side film unwinding assembly and a side film pressing assembly installed on the mounting plate. The mounting plate is slidably installed on the second driving module. The side film unwinding assembly is used to unwind the rolled side film, and the side film pressing assembly cooperates with the first rotary positioning fixture to press the side film tightly on the side surface of the workpiece to be film pasted.

[0015] In some embodiments, the material transfer device includes a first manipulator and a first suction cup assembly. The first manipulator is installed on the machine table, and the first suction cup assembly is installed on the first manipulator. The first suction cup assembly cooperates with the workpiece after being pasted with a film by the first film pasting device. Thus, the material transfer device can realize the automatic transportation of the workpiece after being pasted with a film by the first film pasting device and achieve flow operation.

[0016] In some embodiments, the wireless charger housing film applying device further includes a second rotary positioning jig, which is installed on the machine table and located on one side of the material transfer device. The second rotary positioning jig is used to place the workpiece after being film-applied by the first film applying device and can rotate it. Thus, the material transfer device places the workpiece after being film-applied by the first film applying device into the second rotary positioning jig, and the second rotary positioning jig rotates a certain angle for repositioning and deviation correction.

[0017] In some embodiments, the second film applying device includes a back film applying mechanism, a front film applying mechanism and a workpiece transportation mechanism. The material transfer device is configured to convey the workpiece after being film-applied by the first film applying device to the back film applying mechanism. The back film applying mechanism is configured to apply a film to the back of the workpiece conveyed by the material transfer device. The workpiece transportation mechanism is configured to convey the workpiece after being film-applied by the back film applying mechanism to the front film applying mechanism. The front film applying mechanism is configured to apply a film to the front of the workpiece conveyed by the workpiece transportation mechanism.

[0018] In some embodiments, the second film applying device further includes a bubble pressing mechanism, which is installed on the machine table and located between the back film applying mechanism and the front film applying mechanism. The bubble pressing mechanism is configured to press the workpiece after being film-applied by the back film applying mechanism. The workpiece transportation mechanism can convey the workpiece after being film-applied by the back film applying mechanism to the bubble pressing mechanism and can convey the workpiece after being pressed by the bubble pressing mechanism to the front film applying mechanism. Thus, the bubble pressing mechanism can press the workpiece after being film-applied by the back film applying mechanism again to remove the bubbles in the back film and improve the adhesion.

[0019] In some embodiments, the bubble pressing mechanism includes a bubble pressing assembly and a second vacuum positioning platform. The bubble pressing assembly is slidably installed on the machine table and located above the second vacuum positioning platform.

The first vacuum positioning platform is used to place the workpiece conveyed by the material transfer device. The back film sucking and pressing component is installed on the third driving module. The back film feeding component is used to convey the back film. The back film sucking and pressing component cooperates with the first vacuum positioning platform to suck the back film and press it tightly against the back of the workpiece to be pasted with film. Thus, the working principle of the back film pasting mechanism is as follows: When the workpiece conveyed by the material transfer device is placed on the first vacuum positioning platform, the third driving module drives the back film sucking and pressing component to suck the back film conveyed by the back film feeding component, first move it to directly above the first vacuum positioning platform, and then press it down tightly against the back of the workpiece to be pasted with film.

[0021] In some embodiments, the front film pasting mechanism includes a front film feeding component and a front film sucking and flipping component. The front film feeding component is used to convey the front film.

The workpiece transportation mechanism cooperates with the front film sucking and flipping component to jointly press the front film tightly against the bottom surface of the workpiece. Thus, the working principle of the front film pasting mechanism is as follows: The front film sucking and flipping component runs to above the front film conveyed by the front film feeding component and sucks the front film, and then flips it so that the bonding surface of the front film faces upward. After flipping, the workpiece transportation mechanism conveys the workpiece over. At this time, the workpiece is exactly directly above the front film. The workpiece transportation mechanism drives the workpiece to move downward and jointly cooperate with the front film sucking and flipping component below to press the front film tightly against the bottom surface of the workpiece to complete the film pasting work.
