Description

Technical Field

[0001] The invention belongs to the technical field of mobile phone production equipment, and in particular relates to a precision positioning module suitable for a mobile phone half film and a back cover. Background Art

[0002] Most of the existing mobile phone half-film and back cover positioning fixtures are split-type fixtures, and the materials used to make the fixtures are mostly bakelite, steel and other materials, which cannot effectively prevent static electricity. The electronic components in the product are easily damaged by static electricity, resulting in product defects. After the product is positioned, there is no in-place inspection, and the product status cannot be confirmed.

[0003] Chinese patent CN102267273A discloses a process for attaching a semi-permeable film to a mobile phone lens window. The process uses a fixture to attach a semi-permeable film to the mobile phone lens window, and then removes bubbles under high pressure to make the semi-permeable film fit evenly on the surface of the lens with an ink layer. The steps are: 1. Print ink on the sheet to form a pattern required by the customer; 2. Place the formed lens with the reverse side facing up at the lens fixing position on the fixture; 3. Position the semi-permeable film on the positioning column of the fixture through the positioning hole on the positioning backing paper. After rolling with a rubber roller, the semi-permeable film is attached to the lens, and the positioning backing paper is torn off to remove the lens from the fixture.

[0004] And Chinese patent CN212665871U discloses a fixing fixture for processing the inside of a mobile phone back shell, comprising a base, partitions are arranged on both sides of the inner cavity of the base, the top and bottom of the partitions are fixedly connected to the inner wall of the base, and a first motor is fixedly connected to the bottom of the inner cavity of the base and located between the two partitions. The problem that the fixing fixture for processing the inside of the mobile phone back shell cannot be adjusted and fixed according to the size of the mobile phone back shell is solved. The fixing fixture for processing the inside of the mobile phone back shell has the advantage of being able to be adjusted and fixed according to mobile phone back shells of different sizes, and is worthy of promotion.

[0005] This process uses positioning columns to position the two ends of the semi-permeable membrane respectively. When the mobile phone half membrane is being dusted, it is easy for the mobile phone half membrane to be sucked up by the dust removal head and then deviate, which is not conducive to the precise grasping of the subsequent robot arm; the mobile phone back cover is positioned by clamping, which is easy to damage the appearance of the back cover. The current positioning fixtures and in-place detection devices used for the mobile phone half membrane and the mobile phone back cover are mostly independent working types, cannot be used interchangeably, and are inconvenient to disassemble and replace.
