Description

Technical Field

[0001] The utility model relates to the field of product testing, in particular to product button testing equipment. Background Art

[0002] Keypad testing equipment consists of a product positioning jig and a pressing device. The product is positioned on the positioning jig, and the product and testing device are electrically connected via plug-in connection. The pressing device depresses a key on the product. If the key is good, the testing device indicates it in some way, such as lighting up or sounding a buzzer. If the key is defective, the testing device provides no feedback due to a lack of power. Because keys vary in position or shape on different products, a single, fixed-position pressing device is difficult to adapt to testing keys on different products, resulting in a single application for keypad testing equipment. Utility Model Content

[0003] The technical problem solved by the present invention is as follows: Since the positions of buttons on different products are different, or the shapes of buttons on different products are different, a pressing device with a single shape and fixed position is difficult to adapt to the button testing of different products, resulting in a single application object of the button testing equipment.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a structure compatible with multi-product button testing equipment, including a transferring mechanism arranged on a workbench, a button assembly arranged on the workbench, and a button test needle plate arranged on the workbench, the transferring mechanism including a transferring cylinder and a jig carrier plate connected to the transferring cylinder, and a product jig is positioned on the jig carrier plate; the button assembly includes a button assembly rack and a pen-shaped cylinder arranged on the button assembly rack; the button test needle plate is located at one end of the transferring mechanism, and a button test needle is provided on the button test needle plate. Driven by the transferring cylinder, the product jig comes to the probe test needle and is located below the pen-shaped cylinder. There are a number of pen-shaped cylinders, and the several pen-shaped cylinders are divided into two groups. The two groups of pen-shaped cylinders are arranged in different geometric shapes, and the two groups of pen-shaped cylinders are connected to the rodless cylinder through a connecting plate.

[0005] The product is positioned on the product jig. Driven by the transfer cylinder, the jig and the product on it are moved to the key test pin plate. The key test pins are inserted into the product's sockets. The piston rod of one of the two sets of pen-shaped cylinders descends, pressing the product's key. If the key passes, the test device connected to the key test pins will display some indication, such as a light or buzzer. If the key fails, the test device connected to the key test pins will not display any indication.

[0006] The rodless cylinder can drive two sets of pen-shaped cylinders, with one set positioned above the product, specifically for the product's buttons. This allows two sets of pen-shaped cylinders with different geometric shapes to accommodate button testing on different products, expanding the application range of the button testing equipment.

[0007] A quick clamp is provided on the jig carrier. The quick clamp includes a handle hinged ear located below the jig carrier, a handle hinged to the handle hinged ear, and a U-shaped clamp hinged to the handle. A notch is provided on the edge of the jig carrier to cooperate with the U-shaped clamp, and a snap fit with the U-shaped clamp is provided on the bottom edge of the product jig. Due to the presence of the quick clamp, the product jig can be easily replaced to accommodate different product tests. The handle is rotated upward, driving the U-shaped clamp to rise, and the U-shaped clamp leaves the snap fit. The quick clamp no longer fixes the product jig, and the product jig can be replaced. When fixing the product jig, the handle is rotated downward, and the U-shaped clamp descends, engaging with the snap fit, pressing the product jig down onto the jig carrier.

[0008] The key assembly rack is in a gantry shape, the rodless cylinder is mounted on a crossbeam of the key assembly rack, and the connecting plate is connected to the movable part of the rodless cylinder.

[0009] An industrial camera and light source are mounted on the crossbar of the button assembly rack, pointing toward the product jig below. The camera captures images of the pen-shaped cylinders and the product's buttons to determine whether the arrangement of the pen-shaped cylinders in the set being tested matches the shape of the buttons. The camera images are displayed on a monitor for easy inspection by workers.

[0010] As an option, among the two groups of pen-shaped cylinders, the first group of pen-shaped cylinders are arranged in a rectangular array, and the second group of pen-shaped cylinders are arranged in an X-shaped array to accommodate product buttons of different shapes.

[0011] The utility model provides a structure of a key test device, which provides hardware conditions for the device to be compatible with key tests of various products. BRIEF DESCRIPTION OF THE DRAWINGS
