[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] The vision-based mobile phone frame side hole inspection equipment includes an inspection chassis 1. A dual-station loading port 7 for manual loading is provided on one side of the front of the inspection chassis 1. A loading mechanism 2 for conveying manually loaded parts is provided on the surface of the worktable inside the inspection chassis 1. A left inspection module 3 and a right inspection module 4 for inspecting the parts are respectively provided on both sides of the loading mechanism 2, and an upper barcode scanning module 5 is provided in front of the loading mechanism 2 for inspecting the top of the parts.

[0027] Furthermore, the feeding mechanism 2 includes a motion guide mechanism 21, which is installed in the cavity in the middle of the worktable inside the testing machine housing 1. A motion mechanism 22 is installed on the motion guide mechanism 21, and a first product positioning fixture 23 and a second product positioning fixture 24 are installed on the motion mechanism 22.

[0028] The motion guide mechanism 21 provides the running trajectory for the first product positioning fixture 23 and the second product positioning fixture 24 to enter and exit interchangeably. When the first product positioning fixture 23 or the second product positioning fixture 24 is feeding, another set can descend along the motion guide mechanism 21 to stagger the running paths of the two fixtures and prevent the two fixtures from interfering with each other during interaction.

[0029] Specifically, the motion mechanism 22 consists of a motor, belt and guide rail, which enables the first product positioning fixture 23 and the second product positioning fixture 24 to move back and forth and interchange. Both the first product positioning fixture 23 and the second product positioning fixture 24 consist of product fixture blocks and rotary cylinders, which can place the product to be tested, accurately position the product and rotate the product.

[0030] Furthermore, the left detection module 3 includes a first fixed plate 31, on the surface of which a left motion module 32 is fixedly mounted. This module can move unidirectionally to assist the left vision module 34 in moving and focusing, thus achieving clear visual imaging. A first mounting plate 33 is fixedly mounted on the top of the moving end of the left motion module 32. The left vision module 34 and a left-line laser 35 are fixedly mounted on the top of the first mounting plate 33 to detect the side holes on the left and upper surfaces of the product. The left-line laser 35 performs three-dimensional scanning on the left side and the rotated upper surface of the product to measure the step size.

[0031] Furthermore, the right-side detection module 4 includes a second fixed plate 41, on the surface of which a right motion module 42 is fixedly mounted. This module can move unidirectionally to assist the right vision module 44 in moving and focusing, thus achieving clear visual imaging. A second mounting plate 43 is fixedly mounted on the top of the moving end of the right motion module 42. The right vision module 44 and a right-line laser 45 are fixedly mounted on the top of the second mounting plate 43 to detect the side holes on the right and lower end faces of the product. The right-line laser 45 performs three-dimensional scanning on the right side face and the rotated lower end face of the product to measure the step size.

[0032] Specifically, both the left visual module 34 and the right visual module 44 consist of a camera, a lens, and a light source. The left visual module 34 performs visual imaging on the left side and the rotated upper surface of the product to complete the measurement of the planar dimensions, while the right visual module 44 performs visual imaging on the right side and the rotated lower surface of the product to complete the measurement of the planar dimensions.

[0033] Specifically, longitudinal motion modules 9 are fixedly installed on both sides of the workbench inside the testing machine housing 1. The first fixed plate 31 and the second fixed plate 41 are respectively fixedly installed on the top of the moving ends of the two sets of longitudinal motion modules 9. The left testing module 3 and the right testing module 4 are moved by the cooperation of the two sets of longitudinal motion modules 9.

[0034] Furthermore, the upper scanning module 5 includes a profile column 51, which is fixedly installed on the surface of the workbench inside the inspection box 1. A vision system 52 for recognizing the QR code of the material is fixedly installed on one side of the top of the profile column 51. A ring light source 53 for providing illumination to the vision system 52 is fixedly installed on one side of the profile column 51. The vision system 52 consists of a camera and a lens, which performs visual imaging of the QR code of the product and then the software recognizes it.

[0035] Specifically, a computer monitor 6 is installed on one side of the testing chassis 1. Two sets of testing start buttons 8 are set in front of the dual-station loading port 7 of the testing chassis 1. The circuit connection of the computer monitor 6 and the testing start buttons 8 is a mature existing technology. The specific connection method and working principle will not be elaborated here.

[0036] Working Principle: In use, the product is manually placed onto the first or second product positioning fixture in the feeding mechanism through the dual-station feeding port. (It is worth noting that when the first or second product positioning fixture 24 is at the dual-station feeding port 7, another set is located at the scanning module 5 inside the detection housing 1 for detection.) Through the coordination of the motion guide mechanism 21, motion mechanism 22, first product positioning fixture 23, and second product positioning fixture 24 in the feeding mechanism 2, feeding and measurement can be performed simultaneously. The two sets of longitudinal motion modules... Group 9 works together to move the left detection module 3 and the right detection module 4 respectively. In the left detection module 3, the left motion module 32, the left vision module 34 and the left line laser 35 work together to detect the side holes on the left and top surfaces of the product. In the right detection module 4, the right motion module 42, the right vision module 44 and the right line laser 45 work together to detect the side holes on the right and bottom surfaces of the product. In the upper barcode scanning module 5, the vision system 52 and the ring light source 53 work together to complete the QR code reading of the product through visual imaging, thereby realizing the rapid batch detection of the side hole size of the mobile phone frame.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
