Abstract

According to the touch pen detection device provided by the invention, when the touch pen is tested, the upper needle lifting mechanism drives the upper needle mounting seat to descend, and the upper needle mounting seat drives the upper probe to be in contact with the periphery of the pen point to be electrified; in addition, due to the fact that the pen point is in a conical shape, when the force measuring transverse moving mechanism drives the force measuring block to make contact with the pen point to apply pressure to the pen point, the pen point can slightly move due to the pressure, and therefore the pen point can be prevented from being damaged due to the fact that the force measuring transverse moving mechanism drives the force measuring block to make contact with the pen point to apply pressure to the pen point. Therefore, the upper probe spring pushes the upper probe to cling to the periphery of the pen point, so that the upper probe is not disconnected with the pen point, the upper probe is not interfered by external force, pressure test and electronic function test can be realized in the same work station, and the occupied space and the production cost of equipment are reduced; the invention belongs to the technical field of testing devices.

Description

Technical Field

[0001] The present invention belongs to the technical field of testing devices, and in particular relates to a stylus pen detection device. Background Art

[0002] A stylus is an electronic touch tool used to input commands to computer screens, mobile devices, drawing boards, etc. Users can select files or draw by clicking on the touch screen or touchpad with the stylus. With the popularity of consumer electronic products in daily life, manufacturers want to improve the competitiveness of their products. Today's mainstream styluses are equipped with pressure sensors to issue different commands by the force of the stylus touching the screen.

[0003] In the electronic equipment testing industry, it is common to use a probe to contact the test points on the product to power on or transmit signals for testing. Electronic products with pressure sensors also need to be pressure tested. When performing pressure testing on a product, it is common to apply pressure to the product by driving a pressure plate. As the pressure plate applies pressure to the product, the pressure-bearing part of the product will also move slightly, resulting in the inability to obtain data from the pressure sensor by directly contacting the product with the probe to power it when testing the pressure sensor. Summary of the invention

[0004] The purpose of the present invention is to provide a stylus pen detection device to solve the technical problem described in the background technology.

[0005] The stylus pen detection device comprises a base plate, on which a carrier, an upper needle module and a force measuring module are installed. The carrier is provided with a product slot for placing the stylus pen, and one end of the product slot is provided with an opening for exposing the tip of the stylus pen. The upper needle module comprises an upper needle lifting mechanism located above the base plate, the upper needle lifting mechanism drives an upper needle mounting seat that can be lifted and lowered, the upper needle mounting seat is provided 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 with the outer periphery of the pen tip and energize, the upper needle spring pushes the upper probe to be close to the outer periphery of the pen tip, a ball is provided at the portion where the upper probe contacts the outer periphery of the pen tip, the force measuring module is provided with a force measuring transverse movement mechanism, and the force measuring transverse movement mechanism drives a force measuring block for contacting the pen tip.

[0006] According to the technical solution, the present invention can achieve the following beneficial effects: 1. When testing the stylus pen, the upper needle lifting mechanism drives the upper needle mounting seat to descend, and the upper needle mounting seat drives the upper probe to contact the outer periphery of the pen tip and energize, thereby realizing impedance and current testing of the pen tip and the pressure sensor connected to the pen tip, and realizing electronic function testing of the stylus pen; 2. Since the pen tip is conical, when the force measuring transverse movement mechanism drives the force measuring block 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 be close to the outer periphery of the pen tip, and the upper probe slides on the ballpoint pen tip to ensure that the upper probe is not disconnected from the pen tip, so that the upper probe can be free from interference from external forces; 3. Since the upper probe can be ensured not to be disconnected from the pen tip, when the pressure test of the stylus is performed, there is no need to achieve continuous electrical signal connection with the stylus through wiring, thereby further improving the test efficiency; 4. Pressure testing and electronic function testing can be performed in the same workstation, thereby reducing the equipment footprint and production costs.

[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, the upper needle mounting seat is equipped with an upper needle pressing block. After the upper needle lifting mechanism drives the upper needle mounting seat to descend, the upper needle pressing block is used to press down and fix the pen tip of the stylus pen, and a bracket for supporting the pen tip is provided next to the opening; According to the technical solution, the present invention can further achieve the following beneficial effects: 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 pen, so as to fix the pen tip of the stylus pen in the product slot, so that the upper probe can contact and energize the outer periphery of the pen tip more stably, and at the same time, the force measuring block can apply pressure to the pen tip more stably; 2. The setting of the bracket can effectively avoid the risk of the pen tip bending when the force measuring block applies pressure to the pen tip.

[0009] In some embodiments, the upper needle module includes an upper needle shifting mechanism, which is used to drive the upper needle pressing block and the upper probe to move to or away from above the opening; According to the technical solution, when the stylus pen is placed in the product slot or taken out of the product slot, the upper needle shifting mechanism drives the upper needle pressure block and the upper probe to move away from above the opening, and when the stylus pen is tested, the upper needle shifting mechanism drives the upper needle pressure block and the upper probe to move above the opening, thereby facilitating the operator or automated machinery to load and unload the stylus pen.

[0010] In some embodiments, the bottom plate is installed with a lower needle module, which includes a first-stage lifting mechanism, which drives a first-stage lifting plate that can be lifted and lowered, and a first-stage probe is arranged on the first-stage lifting plate. After the first-stage lifting mechanism drives the first-stage lifting plate to rise, the first-stage probe enters the product slot and contacts the stylus pen to be energized; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. After the stylus pen is placed in the product slot, the first-stage lifting mechanism drives the first-stage lifting plate to rise, and the first-stage probe enters the product slot and contacts the stylus pen to be energized, so as to perform the second functional test on the stylus pen; 2. A second electronic function test can be performed in the same workstation, further reducing equipment footprint and production costs.

[0011] In some embodiments, the first-stage lifting plate is equipped with a second-stage lifting mechanism, the second-stage lifting mechanism drives a second-stage lifting plate that can be lifted and lowered, a second-stage probe is installed on the second-stage lifting plate, and after the second-stage lifting mechanism drives the second-stage lifting plate to rise, the second-stage probe enters the product slot and contacts the stylus pen to be energized; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. When the first-order probe contacts the stylus pen and is powered on, and the second functional test is performed, the second-order lifting mechanism can drive the second-order lifting plate to rise or fall, so that the second-order probe contacts the stylus pen and is powered on, or is separated from the stylus pen, thereby realizing the third functional test; 2. A third electronic function test can be performed simultaneously in the same workstation, thereby further reducing the equipment's footprint and production costs.

[0012] In some embodiments, the second-order lifting plate is provided with a second-order slide groove, a second-order pulley slides in the second-order slide groove, a seesaw is connected to the second-order pulley shaft, the middle of the seesaw is connected to the first-order lifting plate shaft, an auxiliary plate is lifted and slid on the first-order lifting plate, the auxiliary plate is provided with a first-order slide groove, a first-order pulley connected to the other end of the seesaw slides in the first-order slide groove, when the second-order lifting mechanism drives the second-order lifting plate to rise and drives the second-order probe to contact the stylus pen to be energized, the second-order lifting plate pushes the first-order lifting plate down through the seesaw to separate the first-order probe from the stylus pen, and when the second-order lifting mechanism drives the second-order lifting plate to fall, the second-order lifting plate pushes the first-order lifting plate up through the seesaw to enable the first-order probe to contact the stylus pen to be energized; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. When the second-order lifting mechanism drives the second-order lifting plate to drive the second-order probe to rise and contact the stylus, the second-order lifting plate drives one end of the seesaw to rise, and the other end of the seesaw pushes the first-order lifting plate down, so that the first-order probe is separated from the stylus. When the second-order lifting mechanism drives the second-order lifting plate to drive the second-order probe to fall and separate from the stylus, the second-order lifting plate drives one end of the seesaw to fall, and the other end of the seesaw pushes the first-order lifting plate up, so that the first-order probe contacts the stylus and is energized. Therefore, only one power source is needed to realize the contact test between the first-order probe and the second-order probe in sequence, thereby avoiding interference caused by the first-order probe and the second-order probe contacting the stylus at the same time. 2. Since only one power source is required, the space occupied by the equipment and the production cost are further reduced.

[0013] In some embodiments, 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 pen to energize it, and the pre-pressing block is used to fix the stylus pen to connect; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. In the second electronic function test and the third electronic function test, the common probe that contacts the stylus pen channel is set as a pre-probe. After the first-order lifting mechanism drives the first-order lifting plate to rise, the pre-probe contacts the stylus pen in advance and is energized. At the same time, the pre-probe is continuously in contact with the stylus pen and energized during the period when the first-order probe and the second-order probe are in contact with the stylus pen, thereby further reducing the occupied space and production cost of the equipment; 2. Before the second and third electronic function tests, the first-order lifting plate is driven by the first-order lifting mechanism to drive the pre-pressing block to rise, so as to fix or position the stylus in the product slot, so that the first-order probe and the second-order probe can contact the stylus more stably and be energized; 3. Since only two power sources, the first-order lifting mechanism and the second-order lifting mechanism, are needed, it is possible to drive the pre-pressing block to fix the stylus and drive the first-order probe and the second-order probe to contact the stylus in turn, thereby further reducing the occupied space and production cost of the equipment.

[0014] In some embodiments, a pressure cover is connected to a shaft on one side of the carrier, and the pressure cover is used to cover the carrier, and the pressure cover is installed with a pressure block for pressing down and fixing the stylus pen; According to the technical solution, after the stylus pen is placed in the product slot, the pressure cover can be flipped down to cover the carrier, so that the pressure block presses down to fix the stylus pen in the product slot, so that the first-order probe and the second-order probe can contact the stylus pen more stably and be energized.

[0015] In some embodiments, a side pressure slide groove is connected to the side of the product groove, a side pressure spring and a side pressure block are installed in the side pressure slide groove, the side pressure spring pushes the side pressure block away from the product groove, a side of the side pressure block away from the product groove is provided with a push opening, the pressure cover is provided with an oblique push block, after the pressure cover is covered under the carrier, the oblique push block enters the push opening and pushes the side pressure block into the product groove, so as to clamp and fix the stylus; According to the technical solution, after the pressure cover is flipped down and covers the carrier, the oblique push block enters the push opening and pushes the side pressure block into the product slot to clamp and fix the stylus pen. When the pressure cover is flipped up and opened, the oblique 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, thereby releasing the clamping of the stylus pen. Therefore, the present invention can fix and position the stylus pen in a horizontal position without another power source, and at the same time, the stylus pen can be fixed in the product slot more stably.

[0016] In some embodiments, a guide wheel is arranged above one end of the gland connected to the carrier shaft, the guide wheel is higher than the gland in the flipped-up state, a linkage wire is fixed to the other end of the gland, the middle part of the linkage wire bypasses the guide wheel, and the other end of the linkage wire is fixed to the first-stage lifting plate; According to the technical solution, when the first-stage lifting mechanism drives the first-stage lifting plate to descend, the first-stage lifting plate pulls the pressure cover up and opens through the linkage line, and when the first-stage lifting mechanism drives the first-stage lifting plate to rise, the pressure cover can be lowered on the carrier by gravity. Therefore, the first-stage lifting mechanism can be used as a power source to realize the pressure cover flipping up and opening and lowering, thereby reducing the occupied space and production cost of the equipment in one step.

In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

The seat 32 is installed with an upper needle spring 331 and an upper probe 33. After the upper needle lifting mechanism 31 drives the upper needle mounting seat 32 to descend, the upper probe 33 is used to contact the outer periphery of the pen tip 91 and is energized. The upper needle spring 331 pushes the upper probe 33 to fit tightly against the outer periphery of the pen tip 91. A ball 332 is provided at the portion where the upper probe 33 contacts the outer periphery of the pen tip 91. The force measuring module 4 is provided with a force measuring transverse movement mechanism 41. The force measuring transverse movement mechanism 41 can be a cylinder or a screw module, etc. The force measuring transverse movement mechanism 41 drives a force measuring block 42 for contacting the pen tip 91.

[0022] When testing the stylus pen 9, the upper needle lifting mechanism 31 drives the upper needle mounting seat 32 to descend, and the upper needle mounting seat 32 drives the upper probe 33 to contact the periphery of the pen tip 91 to be energized, thereby realizing impedance and current testing of the pen tip 91 and the pressure sensor connected to the pen tip 91, and realizing electronic function testing of the stylus pen 9; since the pen tip 91 is conical, when the force measuring transverse movement mechanism 41 drives the force measuring block 42 to contact the pen tip 91 to apply pressure to the pen tip 91, the pen tip 91 may move slightly due to the pressure, so the upper needle spring 331 pushes the upper probe 33 The upper probe 33 is closely attached to the outer periphery of the pen tip 91, and the upper probe 33 slides on the pen tip 91 by the ball 332, thereby ensuring that the upper probe 33 is not disconnected from the pen tip 91, so that the upper probe 33 can be free from interference from external forces; in addition, since the upper probe 33 is ensured to be not disconnected from the pen tip 91, when the stylus pen 9 is pressure tested, there is no need to achieve continuous electrical signal connection with the stylus pen 9 through wiring, thereby further improving the test efficiency; at the same time, pressure testing and electronic function testing can be achieved in the same workstation, thereby reducing the space occupied by the equipment and the production cost.

[0023] In some embodiments, the upper needle mounting seat 32 is installed with an upper needle pressure block 34. After the upper needle lifting mechanism 31 drives the upper needle mounting seat 32 to descend, the upper needle pressure block 34 is used to press down and fix the pen tip 92 of the stylus 9. A bracket 23 for supporting the pen tip 91 is provided next to the opening 22.

[0024] The upper needle lifting mechanism 31 drives the upper needle mounting seat 32 to descend, and the upper needle mounting seat 32 drives the upper needle pressure block 34 to press down and fix the pen tip 92 of the stylus pen 9, so as to fix the pen tip 92 of the stylus pen 9 in the product slot 21, so that the upper probe 33 can be in contact with the outer periphery of the pen tip 91 more stably and be energized. At the same time, the force measuring block 42 can apply pressure to the pen tip 91 more stably. The setting of the bracket 23 can effectively avoid the risk of bending of the pen tip 91 during the process of the force measuring block 42 applying pressure to the pen tip 91.

[0025] In some embodiments, the upper needle module 3 includes an upper needle shifting mechanism 35 , which may be a cylinder or a screw module, etc. The upper needle shifting mechanism 35 is used to drive the upper needle pressure block 34 and the upper probe 33 to move to or away from above the opening 22 .

[0026] When the stylus pen 9 is placed in the product slot 21 or taken out from the product slot 21, the upper needle shifting mechanism 35 drives the upper needle pressure block 34 and the upper probe 33 to move away from above the opening 22. When the stylus pen 9 is tested, the upper needle shifting mechanism 35 drives the upper needle pressure block 34 and the upper probe 33 to move above the opening 22, thereby facilitating the operator or automated machinery to load and unload the stylus pen 9.

[0027] In some embodiments, the base plate 1 is installed with a lower needle module 5, and the lower needle module 5 includes a first-order lifting mechanism 51. The first-order lifting mechanism 51 can be a cylinder or a screw module, etc. The first-order lifting mechanism 51 drives a first-order lifting plate 52 that can be raised and lowered. A first-order probe 6 is arranged on the first-order lifting plate 52. After the first-order lifting mechanism 51 drives the first-order lifting plate 52 to rise, the first-order probe 6 enters the product slot 21 and contacts the stylus 9 to be energized.

[0028] After the stylus pen 9 is placed in the product slot 21, the first-stage lifting mechanism 51 drives the first-stage lifting plate 52 to rise, and the first-stage probe 6 enters the product slot 21 and contacts the stylus pen 9 to be energized, so as to perform a second functional test on the stylus pen 9; the second electronic function test can be performed in the same work station, thereby further reducing the space occupied by the equipment and the production cost.

[0029] In some embodiments, the first-stage lifting plate 52 is equipped with a second-stage lifting mechanism 7, which may be a cylinder or a screw module, etc. The second-stage lifting mechanism 7 drives a second-stage lifting plate 71 that can be raised and lowered, and a second-stage probe 72 is installed on the second-stage lifting plate 71. After the second-stage lifting mechanism 7 drives the second-stage lifting plate 71 to rise, the second-stage probe 72 enters the product slot 21 and contacts the stylus 9 to be energized.

[0030] When the first-order probe 6 is in contact with the stylus 9 and powered on to perform the second functional test, the second-order lifting mechanism 7 can drive the second-order lifting plate 71 to rise or fall, so that the second-order probe 72 is in contact with the stylus 9 and powered on or separated from the stylus 9, thereby realizing the third functional test; the third electronic functional test can be performed simultaneously in the same workstation, thereby further reducing the occupied space and production cost of the equipment.

[0031] In some embodiments, the second-step lifting plate 71 is provided with a second-step slide groove 73, in which a second-step pulley 74 slides, and a seesaw 75 is connected to the axis of the second-step pulley 74. The middle part of the seesaw 75 is connected to the axis of the first-step lifting plate 52. An auxiliary plate 61 is lifted and slid on the first-step lifting plate 52. The auxiliary plate 61 is provided with a first-step slide groove 62, and a first-step pulley 63 connected to the axis of the other end of the seesaw 75 slides in the first-step slide groove 62. When the second-step lifting mechanism 7 drives the second-step lifting plate 71 to rise and drives the second-step probe 72 to contact the stylus 9 and to be energized, the second-step lifting plate 71 pushes the first-step lifting plate 52 to descend through the seesaw 75, so that the first-step probe 6 is separated from the stylus 9. When the second-step lifting mechanism 7 drives the second-step lifting plate 71 to descend, the second-step lifting plate 71 pushes the first-step lifting plate 52 to rise through the seesaw 75, so that the first-step probe 6 can contact the stylus 9 and be energized.

[0032] When the second-stage lifting mechanism 7 drives the second-stage lifting plate 71 to drive the second-stage probe 72 to rise and contact the stylus 9, the second-stage lifting plate 71 drives one end of the seesaw 75 to rise, and the other end of the seesaw 75 pushes the first-stage lifting plate 52 to descend, so that the first-stage probe 6 is separated from the stylus 9. When the second-stage lifting mechanism 7 drives the second-stage lifting plate 71 to drive the second-stage probe 72 to descend and separate from the stylus 9, the second-stage lifting plate 71 drives one end of the seesaw 75 to descend, and the other end of the seesaw 75 pushes the first-stage lifting plate 52 to rise, so that the first-stage probe 6 is in contact with the stylus 9 and energized. Therefore, only one power source is needed to realize the contact test between the first-stage probe 6 and the second-stage probe 72 and the stylus 9 in turn, thereby avoiding interference caused by the first-stage probe 6 and the second-stage probe 72 contacting the stylus 9 at the same time. In addition, since only one power source is needed, the occupied space and production cost of the equipment are further reduced.

[0033] In some embodiments, a pre-probe and a pre-pressing block 81 are installed on the first-stage lifting plate 52. After the first-stage lifting mechanism 51 drives the first-stage lifting plate 52 to rise, the pre-probe is used to contact the stylus 9 to energize it, and the pre-pressing block 81 is used to fix the stylus 9.

[0034] When performing the second electronic function test and the third electronic function test, the common probe that contacts the channel of the stylus 9 is set as a pre-probe. After the first-order lifting mechanism 51 drives the first-order lifting plate 52 to rise, the pre-probe contacts the stylus 9 in advance and is energized. At the same time, the pre-probe is continuously in contact with the stylus 9 and energized while the first-order probe 6 and the second-order probe 72 are in contact with the stylus 9 and are energized, thereby further reducing the occupied space and production cost of the equipment.

[0035] Before the second and third electronic function tests are performed, the first-stage lifting mechanism 51 drives the first-stage lifting plate 52 to drive the pre-pressing block 81 to rise, so as to fix or position the stylus pen 9 in the product slot 21, so that the first-stage probe 6 and the second-stage probe 72 can be more stably contacted with the stylus pen 9 and powered on. Since only two power sources, the first-stage lifting mechanism 51 and the second-stage lifting mechanism 7, are needed, the pre-pressing block 81 can be driven to fix the stylus pen 9 and the first-stage probe 6 and the second-stage probe 72 can be driven to contact the stylus pen 9 in sequence, thereby further reducing the occupied space and production cost of the equipment.

[0036] In some embodiments, a pressure cover 8 is connected to an axis on one side of the carrier 2, and the pressure cover 8 is used to cover the carrier 2. The pressure cover 8 is installed with a pressure block 81 for pressing down and fixing the stylus 9. The other side of the carrier 2 may be provided with a lock buckle for locking the other side of the pressure cover 8.

[0037] After the stylus pen 9 is placed in the product slot 21 , the pressure cover 8 can be flipped down to cover the carrier 2 , so that the pressure block 81 presses down and fixes the stylus pen 9 in the product slot 21 , so that the first-order probe 6 and the second-order probe 72 can contact the stylus pen 9 more stably and be powered.

[0038] In some embodiments, a side pressure slide groove 24 is connected to the side of the product slot 21, and a side pressure spring 25 and a side pressure block 26 are installed in the side pressure slide groove 24. The side pressure spring 25 pushes the side pressure block 26 away from the product slot 21. A push opening 27 is provided on the side of the side pressure block 26 away from the product slot 21. The pressure cover 8 is provided with an oblique push block 82. After the pressure cover 8 is covered on the carrier 2, the oblique push block 82 enters the push opening 27 and pushes the side pressure block 26 into the product slot 21 to clamp and fix the stylus 9.

[0039] After the pressure cover 8 is flipped down and covers the carrier 2, the oblique push block 82 enters the push opening 27 and pushes the side pressure block 26 into the product slot 21 to clamp and fix the stylus pen 9. When the pressure cover 8 is flipped up and opened, the oblique 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 slot 21, thereby releasing the clamping of the stylus pen 9. Therefore, the present invention can fix and position the stylus pen 9 in a horizontal position without another power source, and at the same time, the stylus pen 9 can be more stably fixed in the product slot 21.

[0040] In some embodiments, a wire pulley 83 is provided above one end of the pressure cover 8 connected to the axis of the carrier 2, and the wire pulley 83 is higher than the pressure cover 8 in the flipped-up state. A linkage line 84 is fixed to the other end of the pressure cover 8, and the middle part of the linkage line 84 bypasses the wire pulley 83, and the other end of the linkage line 84 is fixed on the first-stage lifting plate 52.

[0041] When the first-stage lifting mechanism 51 drives the first-stage lifting plate 52 to descend, the first-stage lifting plate 52 pulls the pressure cover 8 to flip up and open through the linkage line 84, and when the first-stage lifting mechanism 51 drives the first-stage lifting plate 52 to rise, the pressure cover 8 can be covered on the carrier 2 by gravity. Therefore, the first-stage lifting mechanism 51 as a power source can be used to realize the upward and downward covering actions of the pressure cover 8, thereby reducing the occupied space and production costs of the equipment.
