Fig. 1 is a schematic structural diagram of a key testing device according to an embodiment of the present invention. The present invention provides a key test apparatus, as shown in fig. 1, the key test apparatus includes: the electric box 1, the key test motion mechanism 2 and the product clamp 3. Specifically, the electrical box 1 includes a box body 11, a counter 12 and a timer 13 which are arranged in the box body, and a support frame 14 whose lower end is fixed on the box body 11.
The supporting frame 14 is used for supporting the key test motion mechanism 2 above the electrical box 1.
The key test movement mechanism 2 comprises a driving mechanism 21 and a test pressure head 22, the driving mechanism 21 is fixed on the upper part of the support frame 14, the test pressure head 22 is fixed on the lower end of the driving mechanism 21, and the test pressure head 22 is driven by the driving mechanism 21 to press downwards or lift upwards.
The product clamp 3 is fixed on the top of the box body 11 and is positioned below the test pressure head 22. The product clamp 3 is used for clamping a terminal product where a key to be tested is located.
The counter 12 is electrically connected to the driving mechanism 21 for recording and controlling the number of pressing times of the test indenter 22.
The timer 13 is electrically connected with the driving mechanism 21 and is used for controlling the single pressing duration of the test indenter 22.
In this embodiment, when performing a key test on a terminal product, a user may fix the terminal product below the test indenter 22 by using the product clamp 3, and align the key to be tested with the test indenter 22. The test pressure head 22 can press the key to be tested downwards under the driving of the driving mechanism 21, so that the key to be tested is in a pressed state; and can be lifted upwards under the driving of the driving mechanism 21 to release the pressed key to be tested, and one pressing operation on the key to be tested is completed.
The single pressing time of the test indenter 22 is the duration of the pressing of the test indenter 22 on the key from when the test indenter 22 is pressed down to the key to be tested, so that the key to be tested is in the pressed state, to when the test indenter 22 is lifted up to release the pressed key.
According to the key test equipment provided by the embodiment of the invention, the counter 12 which is electrically connected with the driving mechanism 21 and used for recording and controlling the pressing times of the test pressure head 22 is arranged, so that the test on the using times of the key is realized; through setting up with actuating mechanism 21 electricity is connected, is used for control time-recorder 13 when the time is pressed to the single of test pressure head 22 has realized pressing duration's control to the button single, press duration's size through the adjustment single and can press duration to carry out many rounds of button tests to the different single of settlement, thereby can test out the button life under the different single was pressed duration, obtain the influence of button press duration to the button life-span, can effectively simulate real use scene, the precision of button durability test has been improved, can satisfy the test demand.
Fig. 2 is a schematic structural diagram of a key test movement mechanism 2 according to an embodiment of the present invention. On the basis of the above embodiment, as shown in fig. 2, the key test motion mechanism 2 further includes: a displacement sensor (shown as 231 and 232 in fig. 2) for detecting a downward pressing displacement of the test ram 22.
The downward pressing displacement of the test ram 22 refers to a displacement of the test ram 22 in a vertical direction, that is, a displacement of the current position of the test ram 22 relative to the initial position, which is generated when the test ram 22 moves downward from the initial position that is not driven to the current position by the driving mechanism 21.
In this embodiment, the timer 13 is configured to start timing when the downward pressing displacement of the test indenter 22 reaches a preset threshold, and control the driving mechanism 21 to drive the test indenter 22 to lift up to release the pressed key when the timing reaches a set pressing duration.
The preset threshold is the minimum displacement of the test pressure head 22 in the vertical direction when the test pressure head 22 moves downwards from the initial position where the test pressure head is not driven to the position where the key to be tested is pressed under the driving of the driving mechanism 21, so that the key to be tested is in the pressed state. That is, the preset threshold refers to a minimum downward pressing displacement of the test indenter 22 when the test indenter 22 moves downward from an initial position where it is not driven to a position where the key to be tested is pressed by the driving mechanism 21 so that the key to be tested is in a pressed state.
When the downward pressing displacement of the testing pressure head 22 is greater than or equal to the preset threshold value, the key to be tested is in a pressing state under the pressing of the testing pressure head 22; when the downward pressing displacement of the testing press head 22 is smaller than the preset threshold, the key to be tested is in a non-pressed state at this time, which indicates that in the pressing operation of this time, the testing press head 22 has not pressed the key to be tested, or the testing press head 22 lifts upward after pressing the key to be tested and releases the key to be tested.
Optionally, the set duration of the press is set by the technician on a timer 13. Before the key test is performed, the technician may set the set number of times of pressing of the timer 13 through the input device of the timer 13, and the timer 13 may receive and store the set pressing duration set by the technician.
In addition, the technician may reset the set press duration of the timer 13 before each key press test. If the technician does not reset the set pressing duration of the timer 13 before the key test is performed, the timer 13 will use the stored set pressing duration set last time or use the default set pressing duration.
Alternatively, the timer 13 may be connected to the driving mechanism 21 at a point via a first relay and a first solenoid valve. When the timing of the timer 13 reaches the set pressing duration, the timer 13 sends an upward lifting instruction to the first relay, the first relay controls the first electromagnetic valve to send a retraction control signal to the driving mechanism 21 according to the upward lifting instruction, and the driving mechanism 21 drives the test pressure head 22 to lift upward according to the retraction control signal so as to release the pressed key.
In this embodiment, the counter 12 is configured to count once when the downward pressing displacement of the test indenter 22 reaches a preset threshold; and controls the driving mechanism 21 to stop when the count reaches the set number of pressing times.
Specifically, for each pressing operation, the counter 12 counts once when the downward pressing displacement of the test indenter 22 reaches a preset threshold, and during the pressing operation, the counting is not repeated until the test indenter 22 is lifted upward; that is, the counter 12 counts only once for each pressing operation.
The counter 12 is set by a technician for setting the number of pressing operations. Before the key test is performed, the technician may set the set number of pressing times of the counter 12 through the input device of the counter 12, and the counter 12 may receive and store the set number of pressing times set by the technician.
In addition, the technician may reset the set number of presses of the counter 12 before each key press test. If the technician does not reset the set number of presses of the counter 12 before the key test is performed, the counter 12 will either use the stored set number of presses that was last set, or use a default set number of presses.
Further, when the count value of the counter 12 reaches the set number of pressing times, the counter 12 controls the driving mechanism 21 to stop to control the key test device to stop the test.
Alternatively, the counter 12 may be connected to the drive 21 via a second relay and a second solenoid valve. When the count value of the counter 12 reaches the set pressing frequency, the counter 12 sends a stop instruction to the second relay, the second relay controls the second electromagnetic valve to send a stop signal to the driving mechanism 21 according to the stop instruction, and the driving mechanism 21 stops after the testing pressure head 22 is driven to complete the pressing operation according to the stop signal, so that the key testing equipment can be controlled to stop the testing.
In this embodiment, the key movement testing mechanism 2 further includes: the pressure regulating valve 24 (not shown in fig. 2). As shown in fig. 1, a pressure regulating valve 24 may be fixed to the supporting frame 14, and the pressure regulating valve 24 is used to regulate the driving power of the driving mechanism 21 to regulate the pressing pressure of the test indenter 22.
In this embodiment, the pressure regulating valve 24 for regulating the driving power of the driving mechanism 21 is provided, so that the pressing pressure of the test pressure head 22 on the key to be tested is regulated.
Alternatively, as shown in fig. 2, the displacement sensor may include: a first magnetic sensor 231 disposed on the driving mechanism, and a second magnetic sensor 232 fixed on the supporting frame 14.
The first magnetic sensor 231 moves up and down along with the test indenter 22 in the process of the driving mechanism 21 driving the up and down movement of the test indenter 22. Since the second magnetic sensor 232 is fixed on the supporting frame 14, the second magnetic sensor 232 is fixed during the process of driving the test ram 22 to move up and down by the driving mechanism 21. Therefore, when the drive mechanism 21 drives the downward movement of the test indenter 22, the first magnetic sensor 231 approaches the second magnetic sensor 232; and the first magnetic sensor 231 is distanced from the second magnetic sensor 232 when the drive mechanism 21 drives the upward movement of the test indenter 22. When the distance between the first magnetic sensor 231 and the second magnetic sensor 232 is less than or equal to the preset threshold, the second magnetic sensor 232 may sense the first magnetic sensor 231. Therefore, whether the downward pressing displacement of the test indenter 22 reaches the preset threshold value can be detected by the first magnetic sensor 231 and the second magnetic sensor 232.
In addition, in this embodiment, the displacement sensor may also be implemented by any one of the existing sensors or sensing components for measuring the displacement of the movable pressure testing head in the vertical direction when the pressure testing head moves from the initial position to the current position, which is not specifically limited in this embodiment.
Optionally, the driving mechanism 21 includes: a pressing cylinder 211, and a cylinder bracket 212 for fixing the pressing cylinder to the supporting frame.
Further, as shown in fig. 2, the second magnetic sensor 232 may be fixed to the cylinder bracket 212, and since the cylinder bracket 212 is fixed to the support frame 14, the second magnetic sensor 232 is fixed to the support frame 14 through the cylinder bracket 212.
Optionally, the cylinder bracket 212 may be detachably fixed to the supporting frame 14 by screws, and the position of the cylinder bracket 212 may be adjusted up and down to adjust the distance between the testing pressure head 22 and the key to be tested, thereby greatly improving the stability of the key testing apparatus.
Optionally, in order to accurately simulate the flexibility and elasticity of the human finger, the testing press head 22 may be made of high-quality polyurethane or silicone rubber material, so as to improve the key operation simulation effect of the key testing device, and simultaneously, prevent the testing press head 22 from damaging the terminal product to be tested. For example, the testing indenter 22 may be a straight rod with a silicone rubber sleeve, and the end face of one end of the straight rod is designed to be circular arc to simulate the shape of a human finger; the other end is fixed to the lower end of the driving mechanism 21.
Fig. 3 is a schematic structural diagram of a product clamp according to an embodiment of the present invention. As shown in fig. 3, the product holder 3 includes: the clamp comprises a clamp bottom plate 31 fixed at the top of the box body 11, and two L-shaped clamping plates 32 arranged on the clamp bottom plate 31, wherein the vertical parts of the two L-shaped clamping plates and the clamp bottom plate form a placement groove with adjustable width (shown as d in figure 3), the horizontal parts of the two L-shaped clamping plates are positioned outside the placement groove, and the horizontal parts are detachably fixed on the clamp bottom plate 31 through screws 33.
The L-shaped clamp plate 32 is an L-shaped clamp plate composed of a vertical part and a horizontal part, and the vertical part and the horizontal part are perpendicular to each other. The vertical part and the horizontal part are artificially divided for the convenience of describing the structure of the L-shaped clamping plate, and each L-shaped clamping plate is integrally formed to enhance the strength of the L-shaped clamping plate.
Alternatively, the product clamp 3 may be removably secured to the top of the housing 11, and the position of the product clamp 3 relative to the housing 11 may be adjusted.
Optionally, as shown in fig. 1, the electrical box 1 further comprises a test switch 15. When the test switch 15 is turned on, the driving mechanism 21 starts to drive the test ram 22 to move, and when the test switch 15 is turned off, the driving mechanism 21 stops driving the test ram 22. For example, as shown in fig. 1, the test switch 15 is controlled by a start button and a stop button. The user turns on the test switch 15 by pressing the start button and turns off the test switch 15 by pressing the stop button.
In this embodiment, the box 11 of the electrical box 1 is not nearly used for accommodating electrical devices such as the counter 12 and the timer 13, and the box 11 can be used as a base of the key testing device, the key testing movement mechanism 2 and the product clamp 3, so that the key testing device is compact in layout and reasonable in design, and the occupied space of the key testing device is reduced.
The invention provides a key test method, and fig. 4 is a flowchart of the key test method provided by the embodiment of the invention. The invention provides a key test method which can be applied to the key test equipment provided by any one of the embodiments. As shown in fig. 4, the key test method comprises the following steps:
and S101, after the key test equipment is started, driving a test pressure head to move downwards by a driving mechanism to generate downward pressing displacement.
In this embodiment, the user may start the key test device by turning on the test switch. In the process of key test, the user can also force the key test equipment to stop the test by closing the test switch.
In this embodiment, when performing a key test on a terminal product, a user may fix the terminal product below the test pressure head by using the product fixture, and align the key to be tested with the test pressure head.
Before the key testing equipment is started, a user can place a terminal product where a key to be tested is located in a placement groove of a product clamp, and the terminal product is fixed at a proper position by adjusting the position of the product clamp and the relative positions of two L-shaped clamping plates of the product clamp, so that the key to be tested on the terminal product is located under a testing pressure head.
After the key test equipment is started, the test pressure head can press the key to be tested downwards under the driving of the driving mechanism, so that the key to be tested is in a pressed state; and the test pressure head can be lifted up under the drive of the driving mechanism to release the pressed key to be tested, so that one-time pressing operation on the key to be tested is completed.
After the key test equipment is started, the driving mechanism starts to drive the test pressure head to move downwards, and downward pressing displacement is generated.
And S102, when the downward pressing displacement of the test pressure head reaches a preset threshold value, the counter carries out accumulated counting, and meanwhile, the timer starts to time.
In this embodiment, whether the displacement of pressing down through the displacement sensor who sets up can detect the test pressure head in real time reaches and predetermines the threshold value. When the downward pressing displacement of the test pressure head reaches a preset threshold value, the counter carries out accumulative counting, and meanwhile, the timer starts timing.
The preset threshold value refers to the minimum displacement of the testing pressure head in the vertical direction when the testing pressure head moves downwards to press the key to be tested from an initial position where the testing pressure head is not driven and is driven by the driving mechanism, so that the key to be tested is in a pressed state. That is, the preset threshold refers to the minimum downward pressing displacement of the testing pressure head when the testing pressure head moves downward from the un-driven initial position to the pressing of the key to be tested under the driving of the driving mechanism, so that the key to be tested is in the pressing state.
When the downward pressing displacement of the testing pressure head is larger than or equal to a preset threshold value, the key to be tested is in a pressing state under the pressing of the testing pressure head; when the downward pressing displacement of the testing pressure head is smaller than the preset threshold value, the key to be tested is in a non-pressed state at the moment, which indicates that the testing pressure head does not press the key to be tested in the pressing operation, or the testing pressure head lifts upwards after pressing the key to be tested and releases the key to be tested.
In this embodiment, when the downward pressing displacement of the test indenter reaches the preset threshold, the counter performs cumulative counting, and after the timer starts counting, the timer continues to execute step S103 to control the pressing duration of the pressing operation.
And step S103, when the timer counts time to reach a set pressing duration, the timer controls the driving mechanism to drive the test pressure head to lift upwards, and one-time pressing operation simulation and test are completed.
Wherein the set press duration is set by a technician on a timer. Before the key test is carried out, a technician can set the set pressing times of the timer through an input device of the timer, and the timer can receive and store the set pressing duration set by the technician.
In addition, the technician may reset the set press duration of the timer before each key test. If the technician does not reset the set pressing duration of the timer before the key test is performed, the timer will use the stored set pressing duration set last time, or use the default set pressing duration.
And step S104, if the accumulated count of the counter does not reach the set pressing times, the driving mechanism drives the test pressure head to move downwards again, and next pressing operation simulation and test are started.
For each pressing operation, the counter counts for one time when the downward pressing displacement of the test pressure head reaches a preset threshold value, and the counting is not repeated until the test pressure head is lifted upwards in the pressing operation process; that is, the counter performs the count only once for each pressing operation.
The counter is set by a technician to set the number of presses. Before the key test is carried out, a technician can set the set pressing times of the counter through an input device of the counter, and the counter can receive and store the set pressing times set by the technician.
In addition, the technician may reset the set number of presses of the counter before each key press test. If the set number of press times of the counter is not reset by the technician before the key test is performed, the counter will use the stored set number of press times of the last setting, or use the default set number of press times.
And step S105, when the accumulated count of the counter reaches the set pressing times, the counter controls the driving mechanism to stop so as to stop the key test equipment.
When the count value of the counter reaches the set pressing frequency, the counter controls the driving mechanism to stop, and the driving mechanism stops after the driving test pressure head finishes the pressing operation, so that the key test equipment can be controlled to stop the test.
The embodiment of the invention realizes the control of the pressing times of the key by arranging the counter which is electrically connected with the driving mechanism and is used for recording and controlling the pressing times of the test pressure head; through setting up with actuating mechanism electricity is connected, is used for control time-recorder when the time is pressed to the single of test pressure head has realized the control when lasting to pressing of button single, can press time long size through the adjustment single and carry out many rounds of button tests to the different single of settlement press time long to can test out the button life under the different single is pressed, obtain the influence of button duration to the button life, can effectively simulate real use scenario, improved the precision of button durability test, can satisfy the test demand.
