Abstract
Description
Technical Field
[0001] This utility model relates to the field of visual inspection technology, and in particular to a cleaning device for the side buttons of a mobile phone. Background Technology
[0002] After the side buttons for mobile phones are produced, they need to be inspected before shipment to confirm whether there are any damages or deformations on the surface. Due to factors such as the workshop environment and production process, there may be dust and dirt on the product surface, which may be misleading during the inspection as product damage, thus giving back some inaccurate data. Therefore, the product will be cleaned and dust removed before it enters the inspection.
[0003] The existing mobile phone side button testing equipment uses air blowing for cleaning, which uses an electrostatic rod to blow out ion air. The equipment is installed directly above the product and the cleaning is completed while the product is in motion, resulting in poor cleaning effect.
[0004] The main reasons are as follows:
[0005] 1. Air blowing cleaning is a non-contact cleaning method, which cannot effectively clean stubborn dirt and sticky dirt. In addition, there is no collection mechanism for this dirt, and it may cause secondary pollution of the product after being blown into the machine.
[0006] 2. The direction of air blowing cleaning is relatively fixed, blowing from top to bottom, which may leave some dead corners on the side of the product that cannot be cleaned. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide a cleaning device for mobile phone side buttons, which solves the problem that the surface of mobile phone side buttons is dirty and the device's cleaning ability is insufficient, resulting in poor detection imaging effect, a large number of over-scans, and a low device pass rate.
[0008] The technical solution adopted by this utility model to solve its technical problem is: a cleaning device for mobile phone side buttons, including a lint-free cloth cleaning component, a product rotation and conveying component, and a robotic arm conveying component; the product rotation and conveying component cooperates with the lint-free cloth cleaning component to clean the product; the lint-free cloth cleaning component includes a grinding head component, which includes a side wet rubbing grinding head, an R-angle wet rubbing grinding head, and a side and R-angle dry rubbing grinding head arranged in sequence; each grinding head has an outwardly extending arc edge that fits the top surface of the product; the product rotation and conveying component includes a rotating module, which is connected to multiple rotatable cleaning fixtures through a pulley system; the cleaning fixtures are connected to a second lifting module through a connecting plate, and the cleaning fixtures are cleaned at different heights of the lint-free cloth by the second lifting module.
[0009] Furthermore, the cleanroom cloth cleaning component of this utility model also includes a first linear module and a take-up and undo module. The first linear module is connected to a first lifting module. A grinding head assembly is mounted on the first lifting module via a mounting plate. The take-up and undo module takes up and undoes the cleanroom cloth. The grinding head assembly drives the cleanroom cloth to adhere to the side and top surface of the product for wiping and cleaning.
[0010] Furthermore, the R-angle wet rubbing grinding head of this utility model is connected to a telescopic cylinder. When the side and the R-angle dry rubbing grinding head move, the telescopic cylinder drives the R-angle wet rubbing grinding head to retract.
[0011] Furthermore, the product rotation and conveying assembly of this utility model also includes a second linear module, and the second lifting module is disposed on the second linear module.
[0012] The beneficial effects of this utility model are that it solves the defects existing in the background technology. By adding a cleanroom cloth cleaning mechanism and a separate cleanroom cloth cleaning station, it uses a contact cleaning method to clean the sticky dirt and floating dust on the side and top surfaces of the mobile phone's side buttons. The dirt on the product surface is wiped clean, and the cleanroom cloth transfers the dirt to the cleanroom cloth to prevent it from floating inside the equipment. This solves the problem of imaging misjudgment caused by dirt on the product surface, reduces the over-scanning of dirt in the equipment, improves the first pass rate of the equipment, and increases the production capacity of the equipment.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0023] like Figures 1-5 The illustrated device is a cleaning unit for mobile phone side buttons. The entire unit consists of a lint-free cleaning cloth assembly 1, a product rotation and conveying assembly 2, and a robotic arm conveying assembly 3. The robotic arm conveying assembly performs non-destructive loading and unloading of the product 4. The product rotation and conveying assembly works in conjunction with the lint-free cleaning cloth assembly to clean the product. The equipment is a dual-channel system.
[0024] The lint-free cloth cleaning assembly 1 includes a first linear module 12 and a take-up / unwind module 13. The first linear module is connected to a first lifting module 14. A grinding head assembly 11 is mounted on the first lifting module via a mounting plate 15. The grinding head assembly 11 includes a side wet wiping grinding head 112, an R-angle wet wiping grinding head 113, and a side and R-angle dry wiping grinding head 114 arranged sequentially. Each grinding head has an outwardly extending arc edge 115 at its top, which conforms to the top surface of the product. The arc edge ensures that both the sides and top surface of the product can be cleaned. The take-up / unwind module is controlled by a motor to rotate and retract the lint-free cloth. The grinding head assembly drives the lint-free cloth to conform to the sides and top surface of the product for wiping and cleaning. When dry wiping is performed after wet wiping, in order to avoid misoperation caused by interference of the mechanism, the R-angle wet wiping grinding head is connected to the telescopic cylinder 16. When the side and the R-angle dry wiping grinding head move, the telescopic cylinder drives the R-angle wet wiping grinding head to retract, so as to ensure that the dry wiping is not affected by the R-angle wet wiping grinding head.
[0025] The product rotation and handling assembly 2 includes a rotation module 21, which is connected to multiple rotatable cleaning fixtures 23 via a pulley assembly 22. In this embodiment, the rotation assembly can simultaneously control the rotation of six products. The cleaning fixtures are connected to a second lifting module 25 via a connecting plate 24. The cleaning fixtures are cleaned at different heights of the lint-free cloth by the second lifting module, enabling multiple cleanings of the same section of lint-free cloth. Figure 5 The multiple black horizontal lines indicate different areas on the lint-free cloth that can be cleaned.
[0026] The product rotary conveying assembly also includes a second linear module 26, on which the second lifting module is mounted. The linear module is used for the trajectory movement during product handling and side cleaning, and the cleaning fixture can move on the second linear module.
[0027] The products are handled by a robotic arm, which moves six products at a time onto a rotating product handling assembly. The robotic arm then moves the products to two channels in turn.
[0028] The grinding head assembly performs three wiping actions: wet wiping of the sides, wet wiping of the R-angle, and dry wiping of the sides and R-angle. Each grinding head can wipe multiple times, cleaning 6 products at a time, and fully covering the cleaning of the product's sides and top surface.
[0029] The lifting module is used to control the lifting of the grinding head and the product, enabling multiple cleanings of the same piece of cleanroom cloth, which can save on the use of cleanroom cloth, save on consumables, and reduce the frequency of replacing cleanroom cloth.
[0030] The above description is only a specific embodiment of the present utility model. Various examples and illustrations do not constitute a limitation on the substantive content of the present utility model. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the description without departing from the essence and scope of the utility model.
