Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of testing devices, and particularly relates to a stylus testing device. BACKGROUND

[0002] A stylus is an electronic touch tool used to input instructions to a computer screen, a mobile device, a drawing board, etc. A user can select a file or draw by clicking a touch screen or a touchpad with a stylus. With the popularity of consumer electronics in daily life, manufacturers aim to improve the competitiveness of their products. Therefore, the mainstream stylus now has a pressure sensor to send different instructions by the force of the stylus when it touches the screen.

[0003] In the electronic device testing industry, probes are generally used to contact test points on products to test power-on or signal transmission. Electronic products with pressure sensors also need to be tested for pressure. When testing the pressure of a product, a pressure plate is generally used to apply pressure to the product. Since the pressure point of the product will move slightly during the process of the pressure plate applying pressure to the product, it is not possible to directly contact the product with a probe to power on and obtain the data of the pressure sensor when testing the pressure sensor. SUMMARY

[0004] The purpose of the present application is to provide a stylus testing device to solve the technical problems described in the background.

[0005] The stylus testing device comprises a base plate, a carrier, an upper needle module and a force measuring module mounted on the base plate. The carrier is provided with a product slot for placing a stylus. One end of the product slot is provided with an opening for exposing the tip of the stylus. The upper needle module comprises an upper needle lifting mechanism above the base plate. The upper needle lifting mechanism drives a liftable upper needle mounting seat. The upper needle mounting seat is installed with an upper needle spring and an upper probe. After the upper needle lifting mechanism drives the upper needle mounting seat to descend, the upper probe is used to contact and power on the outer periphery of the tip. The upper needle spring pushes the upper probe to tightly contact the outer periphery of the tip. The part where the upper probe contacts the outer periphery of the tip is provided with a ball. The force measuring module is provided with a force measuring horizontal moving mechanism. The force measuring horizontal moving mechanism drives a force measuring block for contacting the tip.

[0006] According to the technical solution, the present application has the following advantages:

[0007] 1. When testing the stylus, the upper needle lifting mechanism drives the upper needle mounting seat to descend. The upper needle mounting seat drives the upper probe to contact and power on the outer periphery of the tip, thereby realizing impedance and current testing of the tip and the pressure sensor connected to the tip, and electronic function testing of the stylus.

[0008] 2. Since the pen tip is conical, when the force measuring block is driven by the force measuring mechanism to contact the pen tip to apply pressure to the pen tip, the pen tip may move slightly due to the pressure. Therefore, the upper needle spring pushes the upper probe to fit tightly against the outer periphery of the pen tip, and the upper probe slides on the ball pen tip to ensure that the upper probe does not break the connection with the pen tip, so that the upper probe can be unaffected by external forces.

[0009] 3. Since it can ensure that the upper probe does not lose connection with the pen tip, there is no need to connect the stylus through wiring to achieve a continuous electrical signal connection when performing pressure tests on the stylus, thereby further improving the testing efficiency.

[0010] 4. It can perform pressure testing and electronic function testing in the same workstation, thereby reducing the space occupied by the equipment and production costs.

[0011] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0012] In some embodiments, the upper needle mounting base is equipped with an upper needle pressure block. After the upper needle lifting mechanism drives the upper needle mounting base to descend, the upper needle pressure block is used to press down and fix the pen tip of the stylus. A bracket for supporting the pen tip is provided next to the opening.

[0013] According to the described technical solution, the present invention further achieves the following beneficial effects:

[0014] 1. The upper needle lifting mechanism drives the upper needle mounting seat to descend, and the upper needle mounting seat drives the upper needle pressure block to press down and fix the pen tip of the stylus, so as to fix the pen tip of the stylus in the product slot, thereby enabling the upper probe to make more stable contact with the outer periphery of the pen tip for power transmission. At the same time, the force measuring block can apply pressure to the pen tip more stably.

[0015] 2. The bracket design effectively avoids the risk of pen tip bending during the pressure applied to the pen tip by the force measuring block.

[0016] In some embodiments, the upper needle module includes an upper needle shifting mechanism for driving the upper needle pressing block and the upper probe to move to or away from the opening;

[0017] According to the technical solution, when the stylus is placed in or removed from the product slot, the upper needle shifting mechanism drives the upper needle pressing block and the upper probe to move away from the opening. When the stylus is tested, the upper needle shifting mechanism drives the upper needle pressing block and the upper probe to move to the opening. Therefore, it is convenient for operators or automated machinery to load and unload the stylus.

[0018] In some embodiments, the bottom plate is provided with a lower needle module, the lower needle module comprises a first lifting mechanism, the first lifting mechanism drives a first lifting plate to be lifted and lowered, a first probe is arranged on the first lifting plate, after the first lifting mechanism drives the first lifting plate to be lifted, the first probe enters the product slot and contacts the stylus to be electrified;

[0019] According to the technical scheme, the application further realizes the following beneficial effects:

[0020] 1. After the stylus is placed in the product slot, the first lifting mechanism drives the first lifting plate to be lifted, the first probe enters the product slot and contacts the stylus to be electrified, so that the second function test of the stylus is realized;

[0021] 2. The second electronic function test can be performed in the same work station, so that the occupied space of the equipment and the production cost are further reduced.

[0022] In some embodiments, the first lifting plate is provided with a second lifting mechanism, the second lifting mechanism drives a second lifting plate to be lifted and lowered, a second probe is arranged on the second lifting plate, after the second lifting mechanism drives the second lifting plate to be lifted, the second probe enters the product slot and contacts the stylus to be electrified;

[0023] According to the technical scheme, the application further realizes the following beneficial effects:

[0024] 1. When the first probe contacts the stylus to be electrified and the second function test is performed, the second lifting mechanism drives the second lifting plate to be lifted or lowered, so that the second probe contacts the stylus to be electrified or is separated from the stylus, thereby realizing the third function test;

[0025] 2. The third electronic function test can be performed in the same work station at the same time, so that the occupied space of the equipment and the production cost are further reduced.

[0026] In some embodiments, the second lifting plate is provided with a second sliding groove, a second pulley is slidably arranged in the second sliding groove, a rocker is connected to the second pulley, the middle part of the rocker is connected to the first lifting plate, the first lifting plate is provided with an auxiliary plate which is lifted and lowered, the auxiliary plate is provided with a first sliding groove, a first pulley is slidably arranged in the first sliding groove and connected to the other end of the rocker, when the second lifting mechanism drives the second lifting plate to be lifted and drives the second probe to contact the stylus to be electrified, the second lifting plate drives the first lifting plate to be lowered through the rocker, so that the first probe is separated from the stylus, when the second lifting mechanism drives the second lifting plate to be lowered, the second lifting plate drives the first lifting plate to be lifted through the rocker, so that the first probe can contact the stylus to be electrified;

[0027] According to the technical scheme, the application further realizes the following beneficial effects:

[0028] 1. When the second-order lifting mechanism drives the second-order lifting plate to raise the second-order probe and make contact with the stylus, the second-order lifting plate raises one end of the rocker, and the other end of the rocker pushes the first-order lifting plate down, causing the first-order probe to separate from the stylus. When the second-order lifting mechanism drives the second-order lifting plate to lower the second-order probe and separate it from the stylus, the second-order lifting plate lowers one end of the rocker, and the other end of the rocker pushes the first-order lifting plate up, causing the first-order probe to make contact with the stylus and be energized. Therefore, only one power source is needed to enable the first-order probe and the second-order probe to make contact with the stylus sequentially, thereby avoiding interference caused by the first-order probe and the second-order probe making contact with the stylus at the same time.

[0029] 2. Since only one power source is needed, the space occupied by the equipment and the production cost are further reduced.

[0030] In some implementations, a pre-probe and a pre-pressing block are installed on the first-stage lifting plate. After the first-stage lifting mechanism drives the first-stage lifting plate to rise, the pre-probe is used to contact the stylus and energize it, and the pre-pressing block is used to fix the stylus.

[0031] According to the described technical solution, the present invention further achieves the following beneficial effects:

[0032] 1. In both the second and third electronic function tests, the common probes of the stylus contact channel need to be set as pre-probes. After the first-stage lifting mechanism drives the first-stage lifting plate to rise, the pre-probes are pre-energized and contacted with the stylus. At the same time, the pre-probes are continuously energized and contacted with the stylus during the period when the first-stage and second-stage probes are energized and contacted with the stylus, thereby further reducing the space occupied by the equipment and the production cost.

[0033] 2. Before conducting the second and third electronic function tests, the first-stage lifting plate is driven by the first-stage lifting mechanism to raise the pre-pressure block, so as to fix or position the stylus in the product slot, thereby enabling the first-stage probe and the second-stage probe to make more stable contact with the stylus and conduct electricity.

[0034] 3. Since only two power sources are needed, namely the first-stage lifting mechanism and the second-stage lifting mechanism, it is possible to drive the pre-compression block to fix the stylus and drive the first-stage probe and the second-stage probe to contact the stylus in sequence, thereby further reducing the space occupied by the equipment and the production cost.

[0035] In some embodiments, a pressure cap is connected to one side of the carrier shaft. The pressure cap is used to cover the carrier and is equipped with a pressure block for pressing down and fixing the stylus.

[0036] According to the technical scheme, after the stylus is placed in the product slot, the lower cover of the pressure cover is placed on the carrier, the pressure block is pressed to fix the stylus in the product slot, and the first-order probe and the second-order probe can be in stable contact with the stylus.

[0037] In some embodiments, the side pressure sliding groove is connected to the side of the product slot, the side pressure spring and the side pressure block are installed in the side pressure sliding groove, the side pressure spring pushes the side pressure block away from the product slot, the side of the side pressure block away from the product slot is provided with a push opening, and the pressure cover is provided with an inclined push block. After the pressure cover is placed on the carrier, the inclined push block enters the push opening to push the side pressure block into the product slot to clamp and fix the stylus.

[0038] According to the technical scheme, after the pressure cover is placed on the carrier, the inclined push block enters the push opening to push the side pressure block into the product slot to clamp and fix the stylus, and when the pressure cover is opened, the inclined push block moves away from the push opening. At this time, the side pressure spring pushes the side pressure block away from the product slot, so that the stylus is released from clamping. Therefore, the present application can realize the fixation and positioning of the stylus in the horizontal position without another power source, and the stylus can be more stably fixed in the product slot.

[0039] In some embodiments, the pressure cover is connected to the carrier shaft, and a wire guide is arranged above one end of the pressure cover. The wire guide is higher than the pressure cover in the upturned state. The other end of the pressure cover is fixed with a linkage wire, the middle part of the linkage wire passes through the wire guide, and the other end of the linkage wire is fixed to the first-order lifting plate.

[0040] According to the technical scheme, when the first-order lifting mechanism drives the first-order lifting plate to descend, the first-order lifting plate pulls the pressure cover to open upward through the linkage wire. When the first-order lifting mechanism drives the first-order lifting plate to ascend, the pressure cover can be placed on the carrier by gravity. Therefore, the pressure cover opening upward and the pressure cover placing downward can be realized by using the first-order lifting mechanism as a power source, thereby reducing the occupied space and production cost of the equipment in one step.

The second electronic functional test can be performed in the same workstation, thereby further reducing the occupied space and production cost of the equipment.

[0062] In some embodiments, the first lifting plate 52 is provided with a second lifting mechanism 7, which can be a pneumatic cylinder or a lead screw module, etc. The second lifting mechanism 7 drives a second lifting plate 71 to move up and down, and a second probe 72 is arranged on the second lifting plate 71. After the second lifting mechanism 7 drives the second lifting plate 71 to move up, the second probe 72 enters the product slot 21 to contact and electrify the stylus 9.

[0063] When the first order probe 6 is in contact with the stylus 9 to be powered on for the second function test, the second order lifting mechanism 7 drives the second order lifting plate 71 to be lifted or lowered, so that the second order probe 72 is in contact with the stylus 9 to be powered on or separated from the stylus 9, thereby realizing the third function test; the third electronic function test can be simultaneously performed in the same work station, thereby further reducing the occupied space of the equipment and the production cost.

[0068] Before the second electronic function test and the third electronic function test are performed, the first lifting mechanism 51 drives the first lifting plate 52 to drive the pre-pressing block 81 to rise, so as to fix or position the stylus 9 in the product groove 21, so that the first probe 6 and the second probe 72 can more stably contact and power the stylus 9. Since only two power sources, the first lifting mechanism 51 and the second lifting mechanism 7, are needed to drive the pre-pressing block 81 to fix the stylus 9 and drive the first probe 6 and the second probe 72 to contact the stylus 9 in turn, the occupied space of the equipment and the production cost are further reduced.

After the pressure cover 8 covers the carrier 2, the inclined push block 82 enters the push opening 27 to push the side pressure block 26 into the product groove 21 to clamp and fix the stylus 9.

[0072] After the pressure cover 8 is turned down to cover the carrier 2, the inclined push block 82 enters the push opening 27 to push the side pressure block 26 into the product groove 21 to clamp and fix the stylus 9, and when the pressure cover 8 is turned up to open, the inclined push block 82 moves away from the push opening 27, at this time, the side pressure spring 25 pushes the side pressure block 26 away from the product groove 21, so as to release the clamping of the stylus 9. Therefore, the present application can realize the fixation and positioning of the stylus 9 in the horizontal position without another power source, and the stylus 9 can be more stably fixed in the product groove 21.

[0073] In some embodiments, a wire wheel 83 is arranged above the end of the cap 8 connected to the shaft of the carrier 2, the wire wheel 83 is higher than the cap 8 in the upturned state, the other end of the cap 8 is fixed with a linkage wire 84, the middle part of the linkage wire 84 passes around the wire wheel 83, and the other end of the linkage wire 84 is fixed to a first lifting plate 52.
