[0002] With the development of technology, the manufacturing accuracy and requirements for 3C products (computers, communications and consumer electronics) are getting higher and higher. This is not only reflected in the conventional industrial camera visual measurement, but also needs to consider the stability of other complex environments, such as complex optical transmittance, specular reflection, diffuse reflection and other optical requirements, such as insulation, thermal insulation, thermal conductivity, heat dissipation, etc. Some special points require corrosion resistance treatment, friction coefficient enhancement or reduction treatment, etc.

[0003] With the development of mobile phones, pads, etc., more and more middle frames or back panels are made of metal, which has good properties and can meet most requirements, but for local or special points (see Fig.10 The position in the white dotted box is the local area or special point that needs passivation treatment), and needs to be treated as mentioned above. Because the material properties are not easy to change, different materials can be matched with lamination, coating, spraying, etc. to form characteristic surfaces with different properties. In this way, the specific needs of different points can be met. Therefore, it is necessary to design a device for surface spraying treatment of 3C products, which can meet the processing requirements of different surfaces such as positive surfaces, corners, inner edges, etc. Summary of the invention

[0020] The loading and unloading module 100 includes a carrier rotating module 110 , a carrier bottom plate 120 , two sets of fixture modules 130 and a fixture flipping driving module 140 .

[0021] Arrangement relationship: The stage rotation module 110 drives the stage bottom plate 120 to rotate in the plane, so as to realize the station exchange of the two sets of fixture modules 130, see Figure 3 That is, the fixture module 130 in the outer preparation area is turned inside to become the processing area, and the fixture module 130 in the inner processing area is turned outside to become the preparation area.

[0022] The two groups of the fixture modules 130 are arranged side by side on the carrier base plate 120 with intervals in front and back, and two fixture flipping driving modules 140 are arranged on the side end surfaces of the two groups of the fixture modules 130 to drive the corresponding groups of multiple bearing and positioning fixtures to flip at a set angle.

[0023] Among them, the stage rotation module 110 and the fixture flipping drive module 140 both include a stage driver 111, a transmission 112 and a turntable 113. The turntable 113 of the stage rotation module 110 is connected to the driving stage base plate 120, and the turntable 113 of the fixture flipping drive module 140 is connected to the fixture module 130.

[0025] Among them, the gantry transfer mechanism of the surface treatment module 200 is a dynamic gantry type space transfer mechanism composed of two Y-axis drive modules 210, an X-axis drive module 220 and a Z-axis drive module 230, and the multiple surface treatment mechanisms 250 are transferred to the active end of the Z-axis drive module 230 through the processing vertical plate 240.

[0026] In a specific example, two Y-axis driving modules 210 are supported by a Y-axis chassis and arranged in parallel and spaced apart; the X-axis driving module 220 is mounted on the same end of the two Y-axis driving modules 210 and driven along the X-direction; the X-axis driving module 220 is driven by the two Y-axis driving modules 210 to move along the Y-direction, wherein one of the two Y-axis driving modules 210 is an active driving unit and the other is a passive transmission balancing unit.

[0027] The Z-axis driving module 230 is disposed on the X-axis driving module 220 and is driven to move along the X-direction. The surface treatment mechanism 250 is driven by the Z-axis driving module 230 to move along the Z-direction. In the illustrated example, the passivator represented by the surface treatment mechanism 250 is a spray gun or an injector, which is used to spray a passivating agent, i.e., a spray, of different requirements.

[0028] The plurality of surface treatment mechanisms 250 of the surface treatment module 200 are driven by the swing driver 260 to swing independently or synchronously.

Of course, the spray can be a chemical liquid, a metal liquid, an organic or inorganic polymer liquid, etc., or it can be particles, etc. Correspondingly, the surface treatment mechanism can be a spray gun or other sprayer, or it can be a laser to perform surface roughening and other processing on specific points and areas on the surface of the middle frame to achieve the aforementioned physical and chemical properties.

[0035] It should be understood that the middle frame in the embodiment of the present invention is a component inside an electronic product that is used to support the electronic product. In other words, the middle frame can be used to fix, place, accommodate or support components of electronic products. For example, the middle frame can be a supporting component for placing a PCB board, chip or battery in an electronic product, or the middle frame can be a supporting component for supporting the screen of an electronic product; the electronic product can also be called an electronic device or terminal, which can include but is not limited to a mobile phone, a mobile computer, a tablet computer (portable android device, Pad), a personal digital assistant (Personal Digital Assistant, PDA), a media player, a smart TV, a smart watch, smart glasses, a smart bracelet, an e-book, a mobile station, etc. The middle frame can be a mobile phone middle frame or front shell, a mobile phone screen support plate, a Pad or computer front shell or screen support plate, etc. The embodiment of the present invention is not limited thereto. Of course, the middle frame can also be a back plate or a combination of a middle frame and a back plate, etc.

[0037] The aforementioned corrosion resistance is not limited to conventional chemical corrosion, but also includes electrical corrosion, such as galvanic corrosion.

[0038] Through the above-mentioned surface treatment equipment, the product materials to be treated can be well treated, such as Fig.10 As shown, surface treatment is performed on special areas or points (white dotted lines) on the back panel, inner short side, inner long side, etc. of the mobile phone middle frame. It is currently mainly used in batches for surface passivation treatment of mobile phone middle frames. Of course, it can also be used for surface treatment scenarios in other 3C, PCB, chip manufacturing and other fields.
