Description

Technical Field

[0001] This utility model belongs to the field of radio frequency connector technology, and in particular relates to a CCD detection device for the coaxiality of radio frequency connectors. Background Technology

[0002] Radio frequency (RF) connectors are commonly used components in electronic devices to connect and transmit RF signals. The accuracy of their coaxiality has a crucial impact on the stability and quality of signal transmission.

[0003] In existing RF connector manufacturing processes, there are many shortcomings in the methods for detecting coaxiality. Traditional testing methods mostly rely on manual operation, with inspectors using experience and simple tools for measurement. This approach is not only inefficient and unable to meet the testing needs of large-scale production, but also susceptible to human error, such as operator fatigue and differences in operating techniques, resulting in poor accuracy and consistency of test results. This can easily lead to defective products being released, and the testing process consumes a significant amount of manpower. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A CCD detection device for coaxiality of an RF connector includes a base, a drive module arranged on the base along its X-axis, a feeding system at the starting end of the drive module, multiple detection mechanisms mounted on the top of the base along the drive path of the drive module, and a throwing system at the ending end of the drive module.

[0006] The multiple sets of detection mechanisms are used for multi-angle detection of RF connectors, including a left visual detection mechanism, a right visual detection mechanism, and an upper visual detection mechanism.

[0007] As a preferred embodiment of the above technical solution, the feeding system includes a feeding carrier and a connecting plate, and the driving module drives the connecting plate to move horizontally along the X-axis.

[0008] As a preferred embodiment of the above technical solution, the material throwing system includes a material unloading chute and a slide table, and the slide table is equipped with material unloading grippers.

[0009] As a preferred embodiment of the above technical solution, the left vision detection mechanism includes a left vision camera, a left vision lens, a left vision light source, a left vision camera mounting plate, and a left vision light source mounting plate. The left vision camera is mounted on the left vision camera mounting plate, the left vision lens is connected to the left vision camera through a universal interface, and the left vision light source is mounted on the left vision light source mounting plate. Furthermore, the center point of the left vision lens, the left vision light source, and any horizontal cross-section of the product under test are located on a straight line.

[0010] As a preferred embodiment of the above technical solution, the right vision detection mechanism includes a right vision camera mounting plate mounted on a base, a right vision light source and a reflecting prism mounted on a feeding carrier, a right vision camera mounted on the right vision camera mounting plate, and a right vision lens mounted at the head end of the right vision camera.

[0011] As a preferred embodiment of the above technical solution, the upper vision inspection mechanism includes an upper vision camera mounting plate installed on a base. The upper vision camera mounting plate is equipped with an upper vision camera and an upper vision light source that are vertically downward. An upper vision lens is installed at the head end of the upper vision camera. The upper vision lens and the upper vision light source are located on the same axis and are directly above the product to be tested.

[0012] The beneficial effects of this utility model are as follows:

[0013] Driven by this practical driving module, the RF connector under test moves along the X-axis and sequentially passes through the left visual inspection mechanism, the right visual inspection mechanism, and the upper visual inspection mechanism to capture images. The captured images are visually processed to calculate the length and coaxiality of the RF connector, determine whether it is qualified, and send the results to the control system. The control system issues a discarding command to the discarding system based on the calculation results. This practical application has the advantages of strong product compatibility, high detection efficiency, high detection accuracy, and low development cost, and has strong application value.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] A CCD detection device for coaxiality of an RF connector includes a base 5, a drive module 4 disposed on the base 5 along its X-axis, a feeding system disposed at the starting end of the drive module 4, the feeding system including a feeding carrier 2 and a connecting plate 3, and the drive module 4 drives the connecting plate 3 to move horizontally along the X-axis; multiple detection mechanisms are disposed on the top of the base 5 along the drive path of the drive module 4, and a throwing system is disposed at the ending end of the drive module 4; the throwing system includes a discharge slide 8 and a slide table 10, and a discharge gripper 9 is mounted on the slide table 10;

[0023] Multiple testing mechanisms are used for multi-angle testing of RF connectors. The multiple testing mechanisms include left visual testing mechanism 1, right visual testing mechanism 6, and upper visual testing mechanism 7.

[0024] When this utility device is working, the drive module 4 is first initialized back to the origin. Then, the product to be tested is correctly placed on the feeding carrier 2. Then, the drive module 4 is controlled by the program to move the feeding carrier 2, the connecting plate 3, and the product to be tested horizontally along the X-axis. The product to be tested is photographed by the left vision inspection mechanism 1, the right vision inspection mechanism 6, and the upper vision inspection mechanism 7 to obtain product images. An image processing algorithm is written to calculate the length L of the RF connector, the two sets of diameters R1 and R2 on the connector, and the coaxiality H = R1 - R2.

[0025] If the length L and coaxiality H of the RF connector are captured in the step, the di is determined to be within the qualified product range. If it is not qualified, the unloading gripper 9 will grab the defective product and slide it into the defective product box via the unloading slide 8. The remaining qualified products will be brought back to the initial position by the drive module 4, and the qualified products will be taken out manually. This process is repeated.

[0026] The following points need to be added to this utility model: the edge of the unloading carrier 2 is lower than the RF connector under test, and the unloading claw 9 can pick up the defective product and put it into the unloading slide 8, which then slides into the defective product storage area; the unloading carrier 2 and the connecting plate 3 are positioned by pins and then fixed by screws, and the whole is designed to be detachable so that different unloading carriers 2 can be replaced to adapt to different models of RF connectors, thereby improving the compatibility of this utility model.

[0027] Before testing, parameters such as the photo location, light source exposure time, and product model of the first product to be tested need to be manually set and recorded in the host computer. Finally, a visual inspection program for the product under different poses under three cameras is written based on the manually acquired images.

[0028] Set the product parameters to be tested:

[0029] Different models of RF connectors have different product names. Before testing, the model name of the product in the carrier needs to be manually entered in the product maintenance interface of the host computer. Manually control the drive module 4 so that the coaxiality feature of the RF connector corresponding to the first photo point of the first product on the unloading carrier 2 is exactly in the center of the camera's field of view and in clear focus. Adjust the light source exposure to achieve the best effect for the feature to be tested and record it in the host computer maintenance interface.

[0030] Set up product test points:

[0031] Different models of RF connectors have different dimensions, numbers, and spacing. To measure multiple products on the loading carrier 2 simultaneously, the coordinates of each product's image capture point are required. The drive module 4 is manually controlled to move the loading carrier 2, ensuring that the coaxiality feature of the RF connector corresponding to the first image capture point of the first product on the loading carrier 2 is precisely centered and clearly focused within the camera's field of view. The image coordinates of the first product under the left and right upper vision inspection system are recorded on the host computer. Then, the image coordinates of other products under test in the left and right upper vision inspection system are calculated using the spacing between two adjacent products. Before testing, the number of products on the loading carrier 2 and the spacing between adjacent products must be manually entered in the product maintenance interface of the host computer.

[0032] Set the product ejection point:

[0033] Manually control the drive module 4 to move the first product on the unloading carrier 2 to the center below the unloading gripper 9. Manually control the unloading gripper 9 to test whether the first product on the unloading carrier 2 can be successfully gripped. If the gripping can be completed, teach and store the throwing point position of the product model during automatic production on the host computer manual debugging interface.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
