Description

Technical Field

[0001] The utility model relates to the field of non-standard automation technology, in particular to a resilience testing device. Background Art

[0002] A key resilience testing device is used to detect the resilience value of a key and can measure various types of keys, such as the keys on a keyboard and the keys on a remote control. Currently, when using a key resilience testing device to measure a key, three operators are required for operation. The hourly output is approximately six hundred. All operations are manual, including taking materials from a blister tray, pressing the start button of the testing machine, observing and judging whether the detection is qualified, and then discharging the materials. The above operation process is all offline operation, which increases the labor intensity of the operators and requires the operators to work continuously for a long time. However, the fatigue state will lead to a decrease in the work efficiency of the operators and an increase in the probability of detection errors. Moreover, manual material taking and discharging may accidentally collide with and scratch the product. Usually, the result of the key resilience test requires the cooperation of a computer to measure the resilience value of the key.

[0003] Then, when the external shapes of the keys are the same, the keys are divided into multiple resilience specifications. During the production process of an electronic circuit board, it is very easy to use the wrong key with the wrong resilience value, resulting in the need for rework of the entire batch of products. However, the current key resilience testing devices are usually large in volume and require the cooperation of a computer, which greatly limits the use environment of the key resilience test.

[0004] Therefore, there is an urgent need for a key resilience testing device that can quickly and accurately detect the resilience value of a key at any time and place. Summary of the Utility Model

[0043] As Figures 1 to 10 shown, this embodiment provides an elastic force testing device for testing a key product 800. A to-be-tested button 810 is provided at the top of the key product 800, and a to-be-tested pin shaft 820 is provided at the end of the key product 800. The elastic force testing device includes a handling component 200, a feeding component 100, and a testing component 300. The handling component 200 has multiple stations for handling the key product 800 between multiple stations.

The testing component 300 is connected to the handling component 200 and includes a positioning module, a preloading module, a button testing module, a pin shaft testing module, and an analysis module. The positioning module is used for secondary positioning of the key product 800. The preloading module is used for preloading the key product 800. The button testing module is used for detecting the elastic force value of the to-be-tested button 810. The pin shaft testing module is used for detecting the elastic force value of the to-be-tested pin shaft 820.

[0044] This elastic force testing device orderly handles the key product 800 between multiple stations through the handling component 200, and cooperates with the settings of the feeding component 100 and the testing component 300 to achieve accurate testing of the elastic force value of the to-be-tested button 810 and the elastic force value of the to-be-tested pin shaft 820. The above components successively complete the feeding (i.e., initial positioning), secondary positioning, preloading, testing of the to-be-tested button 810, and testing of the to-be-tested pin shaft 820 of the key product 800, and determine whether the key product 800 is qualified according to the test results. Through the combined action of the positioning module, the preloading module, the button testing module, and the pin shaft testing module, the accuracy and reliability of the test results are ensured. At the same time, the setting of the analysis module makes data collection and processing more convenient, thereby improving the judgment efficiency of the test, reducing the labor cost, and increasing the accuracy of the test. Moreover, the above structure is convenient for introducing an automated control system, so that the travel of the handling component 200 and the feeding component 100 can be set, and the elastic force value data and test data obtained by the testing component 300 can be saved and exported for visual analysis of the waveform curve to ensure that the quality and specifications meet the requirements. This elastic force testing device reduces the labor intensity of the operators, realizes efficient automated elastic force testing of the key product 800, and avoids the outflow of key products 800 with poor test quality.

[0045] In this embodiment, multiple workstations are divided into a loading workstation, a positioning workstation, a pre-pressing workstation, a button testing workstation, a needle shaft testing workstation, and a testing and discharging workstation. The handling assembly 200 can sequentially convey the button product 800 among the loading workstation, the positioning workstation, the pre-pressing workstation, the button testing workstation, the needle shaft testing workstation, and the testing and discharging workstation. The loading assembly 100 can place and initially position the button product 800 at the loading workstation. The positioning module is used for secondary positioning of the button product 800 at the positioning workstation. The pre-pressing module is used for pre-pressing the button product 800 at the pre-pressing workstation. The button testing module is used to detect the to-be-tested button 810 on the button product 800 at the button testing workstation, and the needle shaft testing module is used to detect the to-be-tested needle shaft 820 on the button product 800 at the needle shaft testing workstation.

[0046] Through the reasonable setting of the workstations, this elastic force testing device realizes the continuous and automated processing of the button product 800. It completes the collaborative operation of the loading workstation, the positioning workstation, the pre-pressing workstation, the button testing workstation, the needle shaft testing workstation, and the testing and discharging workstation, realizes the smooth transition of the button product 800 among the workstations, and ensures the continuity and accuracy of the testing. At the same time, the design of the loading assembly 100 and the positioning module enables the button product 800 to be accurately and quickly placed and initially positioned, providing a stable basis for the subsequent testing work and further improving the testing efficiency.

[0047] In this embodiment, the to-be-tested button products 800 are arranged in a matrix on the plastic suction tray 900, and the plastic suction trays 900 are stacked in multiple layers. The loading assembly 100 is provided with a first in-place sensor 110, a separating mechanism 120, a clamping unit 130, a first loading lead screw module 140, a second loading lead screw module 150, a first material-taking lifting unit 160, a variable pitch unit 170, a picking and placing unit 180, and a stopper 190.

[0048] The first in-place sensor 110 includes a reflective optical fiber for sensing whether the plastic suction tray 900 is in place. The separation mechanism 120 includes a first cylinder for separating the uppermost plastic suction tray 900 from the stacked plastic suction trays 900. The clamping unit 130 includes a second cylinder for clamping the plastic suction tray 900. The clamping unit 130 is disposed on the first loading lead screw module 140, and the first loading lead screw module 140 is used to drive the clamping unit 130 to move along the first direction Y. The pitch-changing unit 170 includes a third cylinder for picking up several key products 800 in groups. The pitch-changing unit 170 is disposed on the first picking lifting unit 160, and the first picking lifting unit 160 is disposed on the second loading lead screw module 150. The second loading lead screw module 150 is used to drive the first picking lifting unit 160 to move along the second direction X to move the key products 800 above the loading station. The first picking lifting unit 160 is used to drive the pitch-changing unit 170 to move along the third direction Z to lift and lower the key products 800. Specifically, the third cylinder picks up four key products 800 in groups.

[0049] When the key products 800 on the plastic suction tray 900 are taken out, the empty plastic suction tray 900 is moved away by the first loading lead screw module 140. The picking and placing unit 180 includes a lifting cylinder for pushing the moved plastic suction tray 900 onto the stopper 190 and stacking them neatly.

[0050] In this embodiment, the elastic force testing device is used to press and test the button under test 810 along the third direction Z and press and test the needle shaft under test 820 along the first direction Y. The first direction Y, the second direction X, and the third direction Z are perpendicular to each other in pairs.

[0051] Exemplarily, the handling assembly 200 includes a PPU (Paralleling and Protection Unit) shifting mechanism. The PPU shifting mechanism is used to handle the key products 800 in groups and includes a transfer rack, a second driving unit 210, a cam guide groove 220, a second in-place sensor 231, and a third in-place sensor 232. A plurality of first suction nozzle units 240 are evenly distributed at intervals on the transfer rack. The second driving unit 210 includes a 400W servo motor for driving the transfer rack to achieve rapid left-right shifting along the cam guide groove 220, so that the first suction nozzle units 240 provided on the transfer rack can reciprocate between two adjacent stations. The second in-place sensor 231 is used to judge whether the first suction nozzle unit 240 reaches the previous station, and at this time, the first suction nozzle unit 240 picks up the key products 800 in groups. The third in-place sensor 232 is used to judge whether the first suction nozzle unit 240 reaches the next station, and at this time, the first suction nozzle unit 240 puts down the key products 800 in groups.

[0052] Exemplarily, the elastic force testing device further includes a defective product discharging assembly 400 and a discharging transfer assembly 500. The defective product discharging assembly 400 is used to store the unqualified key products 800 at the test discharging station, and the discharging transfer assembly 500 is used to discharge the qualified key products 800 at the test discharging station out of the elastic force testing device.

[0053] By introducing the defective product discharging assembly 400 and the discharging transfer assembly 500, the elastic force testing device can automatically distinguish and collect the unqualified key products 800, and at the same time discharge the qualified key products 800 out of the elastic force testing device. This design not only improves the automation degree of the elastic force testing device, but also reduces the error rate of manual sorting, improves the judgment efficiency of the overall test, and ensures the stability and controllability of the quality of the key products 800.

[0054] Further, the discharging transfer assembly 500 includes a first transfer screw module 510, a rotating mechanism carrier 520 and a discharging module. The rotating mechanism carrier 520 is used to carry the key products 800, and the rotating mechanism carrier 520 can drive the key products 800 to rotate around the height direction of the key products 800; the first transfer screw module 510 is used to drive the rotating mechanism carrier 520 to move between the test discharging station and the qualified transfer station; the discharging module is used to discharge the key products 800 located at the qualified transfer station out of the elastic force testing device.

[0055] The design of the first transfer screw module 510, the rotating mechanism carrier 520 and the discharging module in the discharging transfer assembly 500 enables the qualified key products 800 to be conveniently removed from the elastic force testing device, providing convenience for the subsequent process. At the same time, the rotating function of the rotating mechanism carrier 520 enables the key products 800 to be removed after completing the predetermined rotation action, facilitating the subsequent equipment to pick up the qualified key products 800, and thus improving the flexibility of the discharging transfer assembly 500 in working.

[0056] Still further, the rotating mechanism carrier 520 includes a carrier main body, a rotation driving unit 521, a rack 523 and at least one transmission seat. The transmission seat is rotatably connected to the carrier main body. The transmission seat includes a bearing table and a transmission gear 522 fixedly connected to the bearing table. The bearing table is used to carry the key products 800. The output end of the rotation driving unit 521 is used to drive the rack 523 to move along the length direction of the rack 523. The rack 523 is meshed with the transmission gear 522 to drive the transmission seat to rotate around the axis of the transmission gear 522.

[0057] By defining the specific structure of the rotating mechanism carrier 520, the rotating mechanism carrier 520 can stably carry the key products 800 and smoothly drive the key products 800 to rotate, which helps to realize the positioning and adjustment of the key products 800 during the test process, and improves the accuracy and efficiency of the test.

[0058] The discharging module includes a second transfer screw rod module 530, a third material picking and lifting unit 540, a third suction nozzle unit 550, and a transfer lifting unit 560. The second transfer screw rod module 530 is used to drive the transfer lifting unit 560 to move along the second direction X. The transfer lifting unit 560 is used to drive the third material picking and lifting unit 540 to move along the third direction Z. The third material picking and lifting unit 540 is used to drive the third suction nozzle unit 550 to approach or move away from the qualified button products 800.

[0059] The button products 800 are placed on the rotating mechanism carrier 520 and then moved to the rotating position along the first direction Y by the first transfer screw rod module 510. Through the reciprocating linear motion of the rack 523 driven by the rotation driving unit 521, it is converted into the rotational motion of the transmission gear 522. At this time, the second transfer screw rod module 530 also moves to the rotating position, the third material picking and lifting unit 540 descends, the third suction nozzle unit 550 sucks the qualified button products 800, the second transfer screw rod module 530 moves above the first carrier of the next station equipment, and the transfer lifting unit 560 descends to discharge the qualified button products 800 from the elastic force testing equipment.

[0060] In this embodiment, the button testing module includes a first button bearing seat and a button testing table. The first button bearing seat is used to bear the button products 800 at the button testing station, and the first button bearing seat can move between the transfer position and the testing position. When the first button bearing seat is at the transfer position, the handling assembly 200 can pick up and place the button products 800 on the first button bearing seat. When the first button bearing seat is at the testing position, the button testing table can detect the button products 800 on the first button bearing seat.

[0061] With the design of the first button bearing seat and the button testing table, the elastic force testing of the button can be completed accurately and quickly. By moving the first button bearing seat, the position of the button products 800 at the button testing station can be adjusted, so as to plan the layout of the button testing table and the handling assembly 200, thereby avoiding the position conflict between the button testing table and the handling assembly 200, realizing the layout optimization of the elastic force testing equipment, reducing the occupied space, realizing the accurate picking and placing and effective testing of the button, and improving the testing efficiency and quality.

[0062] Furthermore, the button testing table includes a first testing screw rod module, a pressure sensor 360, and a micrometer 370. A button pressing block is connected to the first testing screw rod module. The first testing screw rod module is used to drive the button pressing block. The button pressing block is used to press the testing button products 800. The pressure sensor 360 is used to monitor the pressure at the button pressing block. The micrometer 370 can adjust the relative position between the button pressing block and the first testing screw rod module.

[0063] By using the cooperation of the first test lead screw module, the pressure sensor 360 and the micrometer 370, the extrusion and testing process of the button 810 to be tested becomes more accurate and reliable. The pressure sensor 360 can monitor the pressure changes during the testing process in real time, while the micrometer 370 can adjust the testing parameters to ensure the accuracy and reliability of the testing.

[0064] In this embodiment, the button testing platform uses the first test lead screw module to feed and press the button 810 to be tested. A calibration plate is movably installed on the first test lead screw module, and the end of the calibration plate presses against the micrometer 370. By using the calibration plate to cooperate with the screwing action of the micrometer 370, it is possible to finely adjust until the readings of all the micrometers 370 are the same, so as to ensure that several button pressing blocks are on the same horizontal plane, and all the button pressing blocks simultaneously press the button 810 to be tested on the grouped key products 800.
