Description

Technical Field

[0001] The utility model belongs to the technical field of testing fixtures, and in particular relates to a carrier with a reflector and a testing fixture. Background Art

[0002] In the product automation test line, in order to facilitate the recording of the test process and test results for each product to be tested and the carrier on which the product is placed, an information code is set for each product to be tested and the carrier. Before starting the test work, it is necessary to scan the code and bind the test carrier and each product to be tested placed on the test carrier. If the test product is a flexible cable with a code engraved on the side, a product with a code engraved on the side due to its own structure or without affecting the appearance, and a product that needs to be placed upright in the carrier during testing, after the product is placed in the carrier, the barcode scanner cannot recognize the product's information code. Therefore, in the conventional product automation test line, it is necessary to use a robot to move the product to the front of the barcode scanner to scan the product in advance, and then put the product into the test carrier. The actions of scanning the product code and placing it on the carrier each require the robot to adjust its posture once, so there are multiple posture adjustment actions, resulting in low efficiency in automated testing. Utility Model Content

[0003] The purpose of the utility model is to provide a carrier with a reflector and a test fixture to solve the technical defects described in the background technology.

[0004] The carrier with a reflector includes a carrier plate, the upper surface of the carrier plate is provided with a carrier information code, the carrier plate is installed with a positioning insert, the positioning insert is provided with a product slot for placing a product, both ends of the product slot are provided with clamping positions for fixing both ends of the product, and the side of the product slot is installed with a refractive prism for refracting the product information code on the side of the product to the upper surface of the carrier plate, and the refractive prism maintains a certain distance from the product.

[0005] According to the technical solution, the vehicle with a reflector has the following beneficial effects:

[0006] When testing the product, after the barcode scanner completes scanning above the carrier information code, the barcode scanner only needs to move to the laser emitted from the top of the refracting prism. The laser bends 90° after passing through the refracting prism and irradiates the product information code on the side of the product and reflects. The laser is refracted again by the refracting prism and returns to the barcode scanner to complete the scanning action, thereby completing the binding of the product and the carrier scanning. Therefore, in the process of testing the product, there is no need to use a robot to move the product information code on the side of the product to the front of the barcode scanner for scanning in advance. The product can be placed directly in the product slot, thereby reducing the actions of the test process and shortening the automated test line process. At the same time, it eliminates the accuracy affected by multiple adjustments to the product posture and positioning, and can merge the individual scanning steps of each product into batch scanning, reducing repetitive time and improving the efficiency of automated testing.

[0007] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0008] In some embodiments, a side edge of the product slot is provided with a mounting slot for the refracting prism to slide into and be fixed therein; according to the technical solution, when the refracting prism is accidentally damaged or needs to be cleaned, it is convenient to disassemble and install the refracting prism.

[0009] In some embodiments, a support rod is provided on the side of the product slot, which is located next to the installation slot and is used to support the middle part of the product. According to the technical solution, if the tested product is a flexible flat cable, the product can be supported to prevent it from breaking.

[0010] In some embodiments, a support limiter is provided on the support rod for maintaining a certain distance between the product and the refracting prism and preventing the product from deforming. According to the technical solution, each time the product to be tested is placed in the product slot, each product can be kept at the same distance from the refracting prism, thereby facilitating the barcode scanner to quickly and accurately identify the product information code.

[0011] In some embodiments, the top of the support limiter is provided with an inclined guide surface for vertically sliding the product into the product slot; according to the technical solution, when the product is placed in the product slot, the inclined guide surface is used to guide the product to slide to the specified position, so that the product information code can be quickly and accurately aligned with the refractive surface of the refractive prism, thereby improving the loading speed of the product to be tested.

[0012] In some embodiments, the carrier information code and the refracting prism are arranged on the same straight line; according to the technical solution, after the barcode scanner completes identifying the carrier information code, it moves to the top of the refracting prism to identify the product information code.

[0013] The test fixture comprises a frame, a conveying mechanism and the carrier mentioned above, the conveying mechanism is used to transport the carrier, the frame is provided with a barcode scanner, and the barcode scanner is used to scan the carrier information code and the product information code refracted by the refractive prism.

[0014] According to the technical solution, the test fixture can achieve the following beneficial effects:

[0015] When the test fixture is testing the product, after the barcode scanner completes scanning above the carrier information code, the carrier is moved or the barcode scanner is moved through the conveying mechanism so that the barcode scanner is located above the refracting prism. At this time, the laser emitted by the barcode scanner is bent 90° after passing through the refracting prism to illuminate the product information code on the side of the product and reflect. The laser is refracted again by the refracting prism and returns to the barcode scanner to complete the scanning action. Therefore, when binding the product and the carrier barcode scan, there is no need to set up a robot or action to flip the product side so that the product information code on the side of the product is aligned with the barcode scanner for the barcode scanner to scan the product information code. Therefore, during the entire test process, the actions of the test process are reduced, the process of the automated test line is shortened, and the influence of multiple product posture adjustment and positioning on the accuracy is eliminated. In addition, the individual scanning steps of each product can be merged into batch scanning to reduce repetitive time, thereby improving the efficiency of automated testing.

[0016] In some embodiments, the frame is installed with a screw module that drives the barcode scanning gun to move from above the carrier information code to above the refracting prism; according to the technical solution, when the conveying mechanism is a rotating disk or other non-linear horizontal transport carrier mechanism, after the barcode scanning gun is located above the carrier information code and completes scanning, the barcode scanning gun can be driven by the screw module to move to above the refracting prism to complete scanning the product information code.
