Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, and in particular to a mobile phone mid-frame positioning device. Background Technology

[0002] In the mobile phone manufacturing process, the material feeding process of the mobile phone mid-frame usually adopts the tray feeding mode: first, the mobile phone mid-frame is placed in the tray manually, and then the mobile phone mid-frame is picked up from the tray by a robotic arm and placed on the automated production line.

[0003] However, the existing technology has the following drawbacks: because the tray is prone to large deformation, the CCD imaging positioning method used in conjunction with it is inefficient and lacks precision, resulting in poor positional consistency of the phone frame and failing to meet the positional accuracy requirements of subsequent processes; at the same time, because the product is often misaligned, it is easy to cause damage to the phone frame, affecting product quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mobile phone mid-frame positioning device, which solves the problems of tray deformation affecting positioning, low CCD positioning accuracy and poor efficiency, and easy product misalignment and damage in the prior art, thereby achieving accurate and efficient positioning of the mobile phone mid-frame.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a mobile phone mid-frame positioning device, including a base, on which a sensor module, an inner guide module, an X-axis positioning module and a Y-axis positioning module are arranged; the inner guide module is arranged inside the X-axis positioning module and the Y-axis positioning module; when the mobile phone mid-frame is placed, the sensor module senses the position information of the mobile phone mid-frame, and the inner guide module provides coarse guidance for the mobile phone mid-frame; the X-axis positioning module and the Y-axis positioning module clamp and position the mobile phone mid-frame.

[0008] Furthermore, the Y-direction positioning module of this utility model includes a Y-direction side-push cylinder, a Y-direction positioning block A, and a Y-direction positioning block B. The Y-direction side-push cylinder is drivenly connected to the Y-direction positioning block A, and the Y-direction positioning block B is arranged opposite to the Y-direction positioning block A, with the two respectively located on both sides of the coarse guide channel in the Y direction.

[0009] Furthermore, the sensor module of this utility model includes two photoelectric switches, which are respectively disposed on the base and located between the inner guide block A and the inner guide block B.

[0010] Furthermore, the opposing surfaces of the inner guide block A and the inner guide block B described in this utility model are guide slopes.

[0011] Furthermore, the base of this utility model is also provided with multiple support columns, and the mobile phone frame is placed on the support columns.

[0012] The beneficial effect of this utility model is that it solves the defects existing in the background technology.

[0021] 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.

[0022] like Figures 1-2 The mobile phone frame positioning device shown includes a base 12, on which are disposed an inner guide block A6, an inner guide block B7, an X-direction side push cylinder 1, an X-direction positioning block A2, an X-direction positioning block B5, a Y-direction side push cylinder 3, a Y-direction positioning block A4, a Y-direction positioning block B8, and a photoelectric switch 9.

[0023] The inner guide block B7 is fixedly installed on the base 12, and the base 12 is provided with a sliding groove 13. The inner guide block A6 is slidably disposed in the sliding groove 13. The distance between the inner guide block A6 and the inner guide block B7 is slightly larger than the corresponding size of the mobile phone frame, forming a coarse guide channel for initial guidance when the mobile phone frame is placed in. The opposite surfaces of the inner guide block A and the inner guide block B are guide slopes to facilitate the placement of the product.

[0024] During the process of placing the phone's mid-frame into the positioning device by a robotic arm, direct precision positioning might lead to misalignment due to significant placement deviations by the robotic arm. This could even result in the subsequent clamping of the positioning block by the side-push cylinder, potentially causing damage to the product due to a hard collision with the positioning block. Inner guide blocks A and B, positioned opposite each other, form a coarse guide channel. This channel provides initial guidance and limitation for the placed phone mid-frame, roughly confining the product within the preset positioning area and laying the foundation for subsequent precise clamping and positioning in the X and Y directions.

[0025] Meanwhile, without an internal guide module, the initial position of the product may fluctuate significantly. The side-push cylinder would need a larger stroke adjustment range to adapt to different initial positions, which would not only prolong positioning time but also potentially affect positioning accuracy and equipment lifespan due to frequent large-scale adjustments. The internal guide module reduces the initial position deviation of the product through coarse guidance, allowing subsequent X and Y axis positioning modules to achieve accurate positioning without excessive adjustments, thereby improving overall positioning efficiency and reducing equipment wear and tear.

[0026] X-axis positioning block B5 is fixed on one side of the base, located on one side of the coarse guide channel; X-axis side push cylinder 1 is set on the other side of the base 12, and its piston rod is connected to X-axis positioning block A2. X-axis positioning block A2 is opposite to X-axis positioning block B5, and the clamping surfaces of the two are adapted to the X-axis side of the mobile phone frame.

[0027] Y-direction positioning block B8 is fixed on the base and located on one side of the coarse guide channel; Y-direction side push cylinder 3 is set on the other side of the base 12, and its piston rod is connected to Y-direction positioning block A4. Y-direction positioning block A4 is opposite to Y-direction positioning block B8, and the clamping surfaces of the two are adapted to the Y-direction side of the mobile phone frame.

[0028] Two photoelectric switches 9 are respectively set on the base and located between the inner guide block A6 and the inner guide block B7; used to sense whether the product is in place.

[0029] The base 12 is also equipped with multiple support columns 10, which support the mobile phone frame.

[0030] In actual operation, after the robotic arm grasps the phone's mid-frame, it places it into the coarse guide channel formed by inner guide block A6 and inner guide block B7. The photoelectric switch 9 is triggered, allowing inner guide block A6 to slide and perform an outward pushing action on the phone's mid-frame, completing coarse positioning. Then, the X-axis side-push cylinder 1 is vented, and the piston rod extends, driving the X-axis positioning block A2 to move towards the X-axis positioning block B5 until the X-axis sides of the phone's mid-frame are clamped. At the same time, the Y-axis side-push cylinder 3 is vented, and the piston rod extends, driving the Y-axis positioning block A4 to move towards the Y-axis positioning block B8 until the Y-axis sides of the phone's mid-frame are clamped. At this point, the phone's mid-frame is precisely positioned and can proceed with subsequent processing steps.

[0031] 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.
