Referring to fig. 1 to 3 together, fig. 1 is a schematic structural view illustrating a lifting detection device according to an embodiment of the present invention, in which a mobile terminal is placed, fig. 2 is a top view of fig. 1, fig. 3 is a schematic structural view illustrating a lifting detection device according to an embodiment of the present invention, in which a mobile terminal is not placed, in which the lifting detection device 10 is used to detect whether a lifting mechanism on the mobile terminal is lifted in place, in other words, the lifting detection device 10 of the present embodiment is applicable to the mobile terminal 100 having a lifting mechanism 101 capable of lifting, in which the lifting detection device 10 of the present embodiment includes a table 11, a fixed base 12, a first optoelectronic device 13, a controller 14 (see fig. 4), and an output component 15, in which the table 11a of the table 11 has a positioning region 111, the positioning region 111 is used to position the mobile terminal 100, the fixed base 12 is disposed on the table 11a of the table 11 and located on one side of the positioning region 111, the fixed base 12 has a fixed surface 12a configured to be disposed toward the first end 102 of the mobile terminal 100, the fixed surface 12 is parallel to an end 102 of the mobile terminal 100, in which the fixed surface 12 is disposed parallel to an end 102 of the mobile terminal 100, in which the first optoelectronic device 12 is disposed to be electrically connected to a light emitting a first time control signal output control unit 14, and the first optoelectronic device 100 is used to output a first optoelectronic device 14 for comparing a lifting control unit 14 for outputting a light emitting control signal when the lifting detection device 100 and a light emitting control unit 14 for controlling a light emitting control unit 14 and a time when the lifting detection unit 100 is disposed on the lifting detection unit 100 for comparing a lifting detection unit 100 and a lifting detection unit 100 for outputting a first lifting detection unit 14, the lifting detection unit 100 for outputting a lifting detection unit 14 for outputting a lifting detection unit 100 for outputting a time when the lifting detection unit 14 for outputting a.

The above-mentioned extreme positions of the lifting mechanism 101 extending to the extreme positions relative to the mobile terminal 100 are: the lifting mechanism 101 is at the highest position where it can be extended in a sliding manner relative to the mobile terminal 100.

The preset time is as follows: when the preset lifting mechanism 101 can extend to the position relative to the mobile terminal 100, the first optoelectronic device 13 sends a preset optical signal to the lifting mechanism 101, and the preset optical signal contacts the lifting mechanism 101 and returns to enable the first optoelectronic device 13 to receive the time of the preset optical signal. It is understood that the preset time may be preset according to a preset time when the lifting mechanism 101 is extended to a preset position relative to the mobile terminal 100.

The detection result at least includes whether the lifting mechanism 101 is lifted in place.

By adopting the lifting detection device 10 of the embodiment, the first optoelectronic device 13 is utilized to send the first optical signal L1 to the lifting mechanism 101 extending out to the extreme position, and then the first time is collected and fed back to the controller 14, so that the controller 14 can compare the first time with the preset time and control the output component 15 to output the detection result.

It is understood that the mobile terminal 100 may be, but is not limited to, a mobile phone, a tablet computer, a smart watch, etc. having the lifting mechanism 101. The present embodiment is described by taking a mobile phone as an example.

Alternatively, the table 11 may have a square table shape, and the top surface 11a of the table 11 is the upper surface thereof. It is understood that in other embodiments, the table 11 may be circular truncated or truncated pyramid shaped.

As shown in fig. 4, in consideration of the fact that the mobile terminal 100 should be kept still when the lifting mechanism 101 is moved up and down to prevent the displacement from causing inaccurate detection results, a positioning mechanism 11b may be disposed on the table 11a of the working table 11, and the positioning mechanism 11b may have the positioning area 111, so that the mobile terminal 100 may be positioned by the positioning mechanism 11b to be kept still during the test.

In an alternative embodiment, the positioning mechanism 11b may include a positioning plate 112 and an abutting member 113 disposed on the positioning plate 112, the positioning plate 112 has the positioning area 111, and the abutting member 113 is used for abutting against the mobile terminal 100 when the mobile terminal 100 is placed in the positioning area 111 to prevent the mobile terminal 100 from being displaced. Specifically, the positioning board 112 may be a square board, the upper surface of the positioning board 112 is the positioning region 111, and the area of the positioning region 111 may be larger than that of the mobile terminal 100, so as to completely position and position the mobile terminal 100. It is understood that in other embodiments, the positioning plate 112 may also be a circular plate, a U-shaped plate, or a plate with other shapes, which is not specifically limited in this embodiment.

Further, the positioning plate 112 may be fixed on the table top 11a of the worktable 11 by means of bonding, welding or screwing. For example, the positioning plate 112 may be fixed on the table top 11a of the workbench 11 by a screw connection. For example, screw holes may be provided at four corners of the positioning plate 112 to penetrate the table top 11a of the table 11, and fasteners (e.g., screws, bolts) may be inserted through the screw holes to fix the positioning plate 112 to the table 11. It is understood that, in other embodiments, the positioning plate 112 may be integrally formed on the table top 11a of the working table 11.

Further, the number of the abutting parts 113 may be one or more, and when the number of the abutting parts 113 is multiple, the multiple abutting parts 113 may surround to form a positioning space, and the mobile terminal 100 may be located in the positioning space. Optionally, the plurality of abutting parts 113 are provided, and the plurality of abutting parts 113 are slidably disposed on the positioning board 112, so that when the mobile terminal 100 is placed on the positioning board 112, the plurality of abutting parts 113 can move along a direction toward the mobile terminal 100 until abutting against the outer periphery of the mobile terminal 100, thereby achieving an effect of limiting the mobile terminal 100 at the current position and preventing the mobile terminal 100 from shifting.

Exemplarily, as shown in fig. 1, the number of the abutting parts 113 is 6, and of the 6 abutting parts 113, 2 abutting parts 113 are respectively used for abutting against the first end 102 and the second end (i.e. the end opposite to the first end 102) of the mobile terminal 100, and of the other 4 abutting parts 113, two abutting parts are respectively abutted against two sides of the mobile terminal 100 in the width direction. In this way, the mobile terminal 100 is firmly limited on the positioning board 112 and cannot move, so that the mobile terminal 100 can be effectively kept in the current testing position during testing, and the accuracy of the testing result is ensured.

Further, the supporting member 113 may be a sliding block, and one end of the supporting member 113 for supporting the mobile terminal 100 may be protruded with a protrusion 113a, and the protrusion 113a may be used for supporting the outer periphery of the mobile terminal 100. By adopting the design that the protrusion 113a is disposed on the abutting part 113 for abutting against the outer periphery of the mobile terminal 100, on the basis of satisfying the abutting restriction of the displacement of the mobile terminal 100, the contact area between the abutting part 113 and the mobile terminal 100 can be reduced, and the abrasion of the abutting part 113 to the outer periphery of the mobile terminal 100 can be reduced.

Further, as can be seen from the foregoing, the first end 102 of the mobile terminal 100 is provided with the lifting mechanism 101 that can be lifted up and down, during testing, the lifting mechanism 101 needs to be extended out relative to the mobile terminal 100 (the direction indicated by the forward arrow in fig. 1 is the direction in which the lifting mechanism 101 is extended out relative to the mobile terminal 100, and the direction indicated by the backward arrow in fig. 1 is the direction in which the lifting mechanism 101 is retracted relative to the mobile terminal 100), and the lifting mechanism 101 is generally provided with a camera, so that in order to prevent the lifting mechanism 101 from being worn due to being attached to the upper surface of the positioning plate 112 during the extension and retraction processes, the positioning plate 112 is provided with a clearance groove 114 corresponding to the position of the lifting mechanism 101. The clearance groove 114 is arranged to prevent the lifting mechanism 101 from contacting the upper surface of the positioning plate 112 when the lifting mechanism 101 moves up and down, so that the abrasion of the lifting mechanism 101 can be reduced.

As another alternative embodiment, the positioning mechanism 11b may also only include the positioning plate 112, a positioning groove and a clearance groove 114 communicating with the positioning groove may be disposed on the positioning plate 112, the depth of the positioning groove is smaller than the depth of the clearance groove 114, and the bottom surface of the positioning groove is formed as the positioning area 111, the positioning groove is used for placing the mobile terminal 100, the clearance groove 114 penetrates through one end of the positioning plate 112 facing the fixing base 12 and one end of the positioning groove, so that the clearance groove 114 may be used for implementing clearance for the lifting motion of the lifting mechanism 101. By forming the positioning recess on the positioning plate 112 to position the mobile terminal 100 in a manner that the positioning mechanism 11b is the positioning plate 112, the structural design of the positioning mechanism 11b is simplified, and the positioning of the mobile terminal 100 is facilitated.

In the present embodiment, a solution in which the positioning mechanism 11b includes the positioning plate 112 and the abutting member 113 is taken as an example for explanation.

Optionally, in order to facilitate the taking and placing of the mobile terminal 100 on the positioning board 112, a handle location 115 may be further disposed on the positioning board 112, and the handle location 115 may be used for the taking and placing of the mobile terminal 100. Specifically, the positioning board 112 may be provided with two handle fastening positions 115, the two handle fastening positions 115 are spaced apart and symmetrically disposed with respect to the center of the positioning board 112, when the mobile terminal 100 is positioned on the positioning board 112, the two handle fastening positions 115 are respectively disposed corresponding to two sides of the mobile terminal 100 in the width direction (i.e., the left arrow direction and the right arrow direction in fig. 1), so that when the mobile terminal 100 is taken or placed, two-point positioning taking and placing can be achieved, and the mobile terminal 100 can be taken or placed conveniently.

Specifically, the fastening position 115 may be a groove disposed on the positioning board 112, and an opening of the fastening position 115 may penetrate through one side of the positioning board 112, so that the fastening position 115 has enough space for an operator to place fingers, thereby further facilitating the taking and placing of the mobile terminal 100.

In this embodiment, the fixing base 12 is disposed on the top 11a of the worktable 11 and located at one side of the positioning plate 112, and the fixing surface 12a of the fixing base 12 is disposed just towards one side of the positioning plate 112 where the clearance groove 114 is disposed, so that the optical signal emitted by the first optoelectronic device 13 disposed on the fixing base 12 can only be directed towards the lifting mechanism 101. Specifically, the fixing base 12 may be a square block vertically disposed on the table top 11a of the workbench 11, so that the fixing surface 12a may be disposed perpendicular to the table top 11a of the workbench 11. It is understood that in other embodiments, the fixing base 12 may also be a circular block or a block structure with other shapes, as long as it is vertically disposed on the table top 11a of the workbench 11 and has a working surface perpendicular to the table top 11a of the workbench 11.

The first optoelectronic device 13 is an infrared optoelectronic device, for example, the first optoelectronic device 13 is an infrared optoelectronic device, and the first optoelectronic device 13 is based on the principle of light reflection, that is, when light is vertically incident to an object at 90 °, the light is blocked by the object, and the light can be reflected back to the first optoelectronic device 13 along the original path, so that the first optoelectronic device 13 can collect the time from the light signal emission to the light signal reception.

That is to say, in this embodiment, the first optoelectronic device 13 is mainly used to send an optical signal to the lifting mechanism 101, and whether the lifting mechanism 101 is lifted in place is determined according to a comparison between a time when the first optoelectronic device 13 collects that the lifting mechanism 101 is extended to the limit position relative to the mobile terminal 100 and a time when the first optoelectronic device 13 sends a preset optical signal and collects the preset optical signal when the preset lifting mechanism 101 is extended in place.

Alternatively, the height of the first optoelectronic component 13 on the fastening surface 12a can be set according to the width of the lifting mechanism 101. Specifically, taking the example that when the lifting mechanism 101 extends to a predetermined position relative to the mobile terminal 100, the light signal emitted by the first optoelectronic device 13 contacts an end surface of the lifting mechanism 101 facing the fixing surface 12a, at this time, the setting height of the first optoelectronic device 13 on the fixing surface 12a is suitable.

The width direction of the lifting mechanism 101 is a direction between the front surface of the mobile terminal 100 where the screen is disposed and the back surface of the mobile terminal 100, in other words, the width direction of the lifting mechanism 101 is the thickness direction of the mobile terminal 100.

The preset position is a position where the lifting mechanism 101 extends in position relative to the mobile terminal 100. That is, the above mentioned preset time is the time when the first optoelectronic device 13 sends out the preset light signal and receives the preset light signal when the lifting mechanism 101 extends to the preset position.

Therefore, in the embodiment, whether the lifting mechanism 101 is lifted in place relative to the mobile terminal 100 can be known by comparing the first time with the preset time, and the detection mode is simple and quick and has high detection precision.

Specifically, the first optoelectronic device 13 is configured such that the projection of the first optoelectronic device 13 on the end face of the first end 102 of the mobile terminal 100 is located in the projection area of the lifting mechanism 101 on the end face of the first end 102, and the projection of the first optoelectronic device 13 is located at the projection center of the lifting mechanism 101, so that when the lifting mechanism 101 extends to an extreme position relative to the mobile terminal 100, the first optoelectronic device 13 can send out the first optical signal L1 and collect a first time to be fed back to the controller 14.

Illustratively, with a first time T1, the preset time T, when T1 is T, i.e., the first time is equal to the preset time, the lifting mechanism 101 may be considered to be extended (i.e., lifted) to the full position, i.e., the controller 14 controls the output part 15 to output a result that the lifting mechanism 101 has been extended to the full position, if T1 ≠ T, i.e., the first time is not equal to the preset time, the lifting mechanism 101 may be considered to not be extended to the full position, i.e., the controller 14 controls the output part 15 to output a result that the lifting mechanism 101 has not been extended to the full position, it may be understood that, when T1 ≠ T, there are two cases where the first case is T1 > T, i.e., the first time is greater than the preset time, the lifting mechanism 101 may be considered to be not extended to the full position, i.e., the first optical signal L is emitted in a direction toward the end surface of the first end 102 and returned after contacting the end surface of the first end 102, thereby causing the first time T7 to be greater than the preset time T1, in other words, the second time T L is less than the preset time T L, and thus causing the lifting mechanism to be emitted forward contact the lifting mechanism 101, thus causing the lifting mechanism to be less than the preset time T351, in the preset time T3526, in the lifting mechanism to be less than the preset time T35101, in the.

In some embodiments, in order to determine whether the lifting mechanism 101 is tilted or not after extending, and specifically which position is tilted, the lifting detection apparatus 10 may further include a second optoelectronic device 16 electrically connected to the controller 14, where the second optoelectronic device 16 is disposed on the fixing surface 12a and spaced from the first optoelectronic device 13, the second optoelectronic device 16 is configured to send a second optical signal L2 to the lifting mechanism 101 when the lifting mechanism 101 extends to an extreme position relative to the mobile terminal 100 and collect a second time, and the controller 14 is further configured to compare the second time with the first time, so as to control the output component 15 to output a detection result, where the detection result may include whether the lifting mechanism 101 is lifted in place or not and whether the lifting mechanism 101 is tilted or not.

The second time is the time from the second optoelectronic device 16 sending the second optical signal L2 to the lifting mechanism 101 to receiving the second optical signal L2.

Further, the second optoelectronic device 16 is configured such that a projection on the end face of the first end 102 is located in a projection area of the lifting mechanism 101 on the end face of the first end 102, and the second optoelectronic device 16 and the first optoelectronic device 13 are respectively disposed on opposite sides of the lifting mechanism 101, and the projections of the second optoelectronic device 16 and the first optoelectronic device 13 on the end face of the first end 102 are symmetrical with respect to a projection center of the lifting mechanism 101. In this way, the first optoelectronic device 13 and the second optoelectronic device 16 can be ensured to detect the two sides of the lifting mechanism 101 respectively during detection, and the situation that the two sides of the lifting mechanism 101 are deviated and cannot be detected due to too concentrated arrangement between the first optoelectronic device 13 and the second optoelectronic device 16 is avoided.

For example, as shown in fig. 1, the first optoelectronic device 13 may be disposed corresponding to the left side of the lifting mechanism 101, and the second optoelectronic device 16 may be disposed corresponding to the right side of the lifting mechanism 101. The directions of front, back, left, right, up, down, etc. shown in fig. 1 are only examples for convenience of description and understanding of the scheme, and do not limit the scope of the present embodiment.

Further, the distance from the first optoelectronic device 13 to the edge of the lifting mechanism 101 is 0-1mm, and the distance from the second optoelectronic device 16 to the edge of the lifting mechanism 101 is 0-1 mm. That is, the first and second

optoelectronic devices

13 and 16 should be disposed corresponding to the side edge of the lifting mechanism 101 as much as possible, so as to avoid the side edge of the lifting mechanism 101 from being deviated and skewed and being unable to be detected, thereby improving the detection accuracy of the lifting detection apparatus 10. Illustratively, the distance between the first optoelectronic device 13 and the second optoelectronic device 16 to the edges of the two sides of the lifting mechanism 101 is 0-0.5mm, so as to be correspondingly arranged close to the side edges of the lifting mechanism 101 as much as possible, thereby improving the detection accuracy. It is understood that the distances from the first optoelectronic device 13 and the second optoelectronic device 16 to the two side edges of the lifting mechanism 101 can also be 0.6mm, 0.7mm, 0.8mm, and so on.

The first photoelectronic device 13 and the second photoelectronic device 16 are both infrared photoelectronic devices, on one hand, emitted infrared rays are invisible to naked eyes, and damage to eyes of detection personnel is avoided, on the other hand, the infrared photoelectronic devices are small in size and low in cost, and the space occupation of the detection device is reduced, and the cost is saved.

The following description will be made about the case where the second optoelectronic device 16 and the first optoelectronic device 13 detect whether the lifting mechanism 101 is extended in position, as follows:

when the lifting mechanism 101 extends forward to an extreme position relative to the mobile terminal 100, the first optoelectronic device 13 and the second optoelectronic device 16 simultaneously emit a first optical signal L1 and a second optical signal L2, the first optoelectronic device 13 collects a first time and feeds the first time back to the controller 14, and the second optoelectronic device 16 collects a second time and sends the second time to the controller 14, so that the controller 14 compares the first time with a preset time according to the received first time and the received second time, and compares the second time with the first time and the preset time.

Taking the preset time T, the first time T1, and the second time T2 as examples, it can be seen from the above that, since the first optoelectronic device 13 and the second optoelectronic device 16 are symmetrically arranged with respect to the center of the lifting mechanism 101, when the lifting mechanism 101 is pre-set to extend to the preset position, the first time collected by the first optoelectronic device 13 is equal to the second time collected by the second optoelectronic device 16, and this is also equal to the preset time T, i.e. T1 is equal to T2. When the lifting mechanism 101 extends to the limit position relative to the mobile terminal 100, the controller 14 compares the received T1 and T2, and if T1 ≠ T2, it indicates that the lifting mechanism 101 is tilted in the lifting offset position, and the controller 14 controls the output unit 15 to output the result of the lifting offset position of the lifting mechanism 101. Of course, it is understood that it is also possible to determine which side of the lifting mechanism 101 has lifting skew according to the magnitude of the first time and the second time. For example, when T1 > T2, it indicates that the left side of the lift mechanism 101 is not extended to the right and is skewed. When T1 < T2, it indicates that the right side of the lifting mechanism 101 is not extended to the right and is skewed.

Further, as can be seen from the foregoing, it is necessary to determine whether the lifting mechanism 101 is extended in place, and therefore, the second time needs to be further compared with the preset time. For example, when T1 ≠ T2 ≠ T, it can be said that the lifting mechanism 101 is not extended in position, and the output component 15 outputs the result that the lifting mechanism 101 is not output in position. It is understood that T1 ═ T2 ≠ T also includes two cases: in the first case, T1 is T2 < T, which indicates that the lifting mechanism 101 is not extended in place, and T1 is T2 > T, which indicates that the lifting mechanism 101 is extended beyond the preset position.

Therefore, by arranging the first optoelectronic device 13 and the second optoelectronic device 16, the first optoelectronic device 13 and the second optoelectronic device 16 respectively send the first optical signal L1 and the second optical signal L2 to the lifting mechanism 101 and respectively collect the first time and the second time when the lifting mechanism 101 extends to the limit position relative to the mobile terminal 100, so that whether the lifting mechanism 101 is lifted in place or not can be determined according to the comparison between the first time and the second time and the comparison between the first time and the preset time, and whether the lifting mechanism 101 is lifted in place or not can be determined when the lifting mechanism 101 is not lifted in place.

In some embodiments, the controller 14 may be disposed inside or outside the table 11. Alternatively, the controller 14 may be disposed inside the worktable 11, a circuit board may be disposed inside the worktable 11, and the controller 14 may be integrated on the circuit board, and the circuit connection of the first and second

optoelectronic devices

13 and 16 may be realized through the circuit board. In particular, the first and second

optoelectronic components

13, 16 can be wired from the side of the mounting plate facing away from the mounting surface 12a towards the inside of the table 11, so as to be wired to the circuit board and thus electrically connected to the controller 14.

The controller 14 is arranged inside the workbench 11, so that the overall structure of the detection device is more compact, and meanwhile, the controller 14 is arranged inside the workbench 11, so that the wiring of the first optoelectronic device 13 and the second optoelectronic device 16 is simpler.

It is understood that in other embodiments, the controller 14 may be disposed outside the workbench 11, and for example, a control box may be disposed outside the workbench 11, and the controller 14 may be disposed in the control box.

In some embodiments, the output component 15 may be disposed on a side of the worktable 11 connected to the table 11a of the worktable 11, so that the inspector can know the detection result in time. For example, the output member 15 may be disposed on a surface of the table 11 facing the rear end, which is a surface facing the inspector, so that the inspector can quickly know the result output by the output member 15.

Further, the output part 15 may include any one of a display, a buzzer, a vibrator, and a light emitting part. Illustratively, the output unit 15 is a buzzer, which is integrated with a light emitting diode, and can not only output a prompt sound to prompt a detection result of a detection person, but also indicate the detection result of the detection person by emitting light, which is beneficial for the detection person to know the detection result quickly. For example, when the first time and the second time are equal to the preset time, that is, T1 is T2 is T, and at this time, the lifting mechanism 101 is extended in place, the buzzer does not sound at this time, but the light emitting diode on the buzzer emits a green light, and the inspector can quickly determine that the lifting mechanism 101 is extended in place according to the green light, so that the current mobile terminal 100 after detection can be removed and replaced with a new mobile terminal 100. When the first time is equal to the second time but not equal to the preset time, for example, T1-T2 < T or T1-T2 > T, the buzzer sounds an alarm, and at the same time, the light emitting diode thereon emits red light, so that the inspector can quickly know that the lifting mechanism 101 is not extended in place. When the first time is not equal to the second time, for example, T1 is greater than T2 or T1 is less than T2, the buzzer can also give out an alarm, and the light emitting diode thereon emits yellow light, so that the inspector can quickly know that the lifting mechanism 101 is deviated and tilted.

The output part 15 adopts the buzzer, can not only send sound to remind but also send light to remind the detection personnel test result fast, and the learning of test result is more directly perceived.

It is understood that, when the output part 15 is a display, the detection result can be output on the display, such as whether the lifting mechanism 101 is extended in place, and which side of the lifting mechanism 101 is deviated and skewed, so that the detection result can be timely viewed by the detection personnel according to the content on the display.

Further, in order to facilitate the operation of the detection apparatus, a switch button 17 may be further disposed on the working platform 11, and the switch button 17 is electrically connected to the controller 14 and the first and second

optoelectronic devices

13 and 16 to control the operation or the shutdown of the first and second

optoelectronic devices

13 and 16 and the operation or the shutdown of the controller 14.

According to the lifting detection device 10 disclosed by the embodiment, through the arrangement of the first photoelectronic device 13 and the second photoelectronic device 16, the first time and the second time acquired by the first photoelectronic device 13 and the second photoelectronic device 16 are compared with the preset time, so that whether the lifting mechanism 101 extends in place or not can be quickly determined, the detection mode is simple and quick, the detection efficiency is high, and the detection precision is also high.

In addition, the lifting detection device 10 is simple in structure and compact in overall structure, and detection cost is reduced.

Example two

Referring to fig. 1, fig. 2 and fig. 5, fig. 5 is a flowchart illustrating a lifting detection method according to the present embodiment. The lifting detection method of the embodiment is implemented by using the lifting detection device in the first embodiment, and includes the following steps:

201. and placing the mobile terminal provided with the lifting mechanism on a workbench.

In this embodiment, during detection, the mobile terminal needs to be placed on the workbench 11, and the position of the mobile terminal 100 on the workbench 11 is kept unchanged, so that the mobile terminal is always kept still in the process of extension and retraction of the lifting mechanism 101, and the mobile terminal is prevented from being displaced to influence the extension and retraction detection result of the lifting mechanism 101.

As an alternative embodiment, the mobile terminal 100 may be automatically placed on the workbench 11 by a robot cooperating with a camera, specifically, the camera captures a positioning area 111 on the workbench 11 for placing the mobile terminal 100 and a current position of the mobile terminal 100, and then controls the robot to place the mobile terminal 100 on the positioning area 111 of the workbench 11, and fix the mobile terminal 100 on the positioning area 111.

As another alternative, the mobile terminal 100 may be manually placed on the working platform 11 by an inspector through manual loading.

203. When the lifting mechanism extends to the limit position relative to the mobile terminal, the first photoelectronic device is controlled to send out a first optical signal and collect first time.

Specifically, the lifting mechanism 101 is controlled to extend out of the mobile terminal 100 relative to the mobile terminal 100 and extend to an extreme position where the lifting mechanism can extend out of the mobile terminal 100, at this time, the controller 14 may control the first optoelectronic device 13 to send the first optoelectronic signal to the lifting mechanism 101, and control the first optoelectronic device 13 to collect the first time and send the first time to the controller 14, where the first time is a time from when the first optoelectronic device 13 sends the first optical signal L1 to when the first optoelectronic device receives the first optical signal L1.

Alternatively, the first optoelectronic device 13 may be an infrared optoelectronic device that has signal transmitting and signal receiving functions as a whole, and the first optical signal L1 emitted by the first optoelectronic device 13 may be a first infrared signal.

205. The controller compares the first time with a preset time.

Whether the lifting mechanism 101 extends in place or not can be rapidly known by comparing the first time with the preset time.

The preset time is preset, and when the lifting mechanism 101 extends in place relative to the mobile terminal 100 to a preset position, the first optoelectronic device 13 sends a preset optical signal until the preset optical signal is received. In other words, the preset time can be preset in advance and stored in the controller 14, and the preset position can also be preset.

The first time is the time from the first optoelectronic device 13 emitting the first optical signal L1 to receiving the first optical signal L1.

Taking the first time as T1 and the preset time as T, the two have the following relationship:

for example, when T1 is T, the lifting mechanism 101 is extended into position. When T1 ≠ T, e.g., T1 > T, it indicates that the lifting mechanism 101 extends out of the protruding preset position; when T1 < T, it indicates that the lifting mechanism 101 is not extended to the right.

207. The controller controls the output part to output the detection result.

For example, the output member 15 may be a display, a buzzer, a vibrator or a light emitting component, and when the output member 15 is a display, it may output the detection result in the form of characters, for example, the detection result is that the lifting mechanism 101 is extended or not extended in place, or the characters are referred to in the form of OK or NG. By adopting a display mode, the output result is visual, and the detection personnel can conveniently check the result.

For example, the output part 15 may also be a buzzer, and the buzzer is integrated with a light emitting diode, so that the buzzer can output the detection result in a form of sound and light, for example, when the detection result is that the lifting mechanism 101 is lifted and extended, the buzzer may not sound, but only control the light emitting diode to emit green light, and when the detection result is that the lifting mechanism 101 is not extended in place, the buzzer may emit an alarm sound and control the light emitting diode to emit red light. By adopting the buzzer, the detection result can be conveniently and timely reminded to the detection personnel to check, and meanwhile, the detection result is more visual.

The lifting detection method disclosed by the second embodiment of the invention is realized by using the lifting detection device 10, the detection mode is simple and reliable, and the detection efficiency and the detection precision are high.

EXAMPLE III

Referring to fig. 1, fig. 2 and fig. 6 together, fig. 6 is another flowchart of a lifting detection method disclosed in a third embodiment of the present invention, in which the detection method of the third embodiment is implemented by using the lifting detection device in the first embodiment, and the detection method includes the following steps:

301. and placing the mobile terminal provided with the lifting mechanism on a workbench.

303. When the lifting mechanism extends to the limit position relative to the mobile terminal, the first photoelectronic device is controlled to send a first optical signal and collect first time, and the second photoelectronic device is controlled to send a second optical signal and collect second time.

In this embodiment, the second optoelectronic device 16 may also be an infrared optoelectronic device, such that the second optical signal L2 emitted therefrom is a second infrared optical signal.

When the lifting mechanism 101 extends to an extreme position relative to the mobile terminal 100, the controller 14 may control the first and second

optoelectronic devices

13 and 16 to simultaneously emit the first and second optical signals L1 and L2 and collect a first time and a second time, respectively, where the second time is a time from when the second optoelectronic device 16 emits the second optical signal L2 to when the second optical signal L2 is received.

305. The controller compares the first time with a preset time, and the controller compares the second time with the first time, and the controller compares the second time with the preset time.

Specifically, in this step, the controller 14 may determine whether the lifting mechanism 101 is extended in place, and whether the extending deviation and the skew occur by controlling the first time, the second time and the relationship with the preset time.

For example, taking the preset time T, the first time T1, and the second time T2 as examples, it can be seen from the above that, since the first optoelectronic device 13 and the second optoelectronic device 16 are symmetrically disposed relative to the center of the lifting mechanism 101, when the lifting mechanism 101 is pre-set to extend to the preset position, the first time collected by the first optoelectronic device 13 is equal to the second time collected by the second optoelectronic device 16, and this is also equal to the preset time T, i.e., T1 is equal to T2. When the lifting mechanism 101 extends to the limit position relative to the mobile terminal 100, the controller 14 compares the received T1 and T2, and if T1 ≠ T2, it indicates that the lifting mechanism 101 is tilted in the lifting offset position, and the controller 14 controls the output unit 15 to output the result of the lifting offset position of the lifting mechanism 101. Of course, it is understood that it is also possible to determine which side of the lifting mechanism 101 has lifting skew according to the magnitude of the first time and the second time. For example, when T1 > T2, it indicates that the left side of the lift mechanism 101 is not extended to the right and is skewed. When T1 < T2, it indicates that the right side of the lifting mechanism 101 is not extended to the right and is skewed.

Therefore, according to the comparison between the first time and the second time, and the comparison between the first time and the preset time, it can be determined whether the lifting mechanism 101 is lifted in place, and whether the lifting mechanism 101 is deviated or skewed when the lifting mechanism 101 is not lifted in place. Therefore, by adopting the embodiment, the lifting in-place detection efficiency of the lifting mechanism 101 can be improved, and meanwhile, the lifting in-place detection precision of the lifting mechanism 101 can also be effectively improved.

307. The controller controls the output part to output the detection result.

In the method for detecting the lifting in place of the lifting mechanism 101 disclosed in the third embodiment of the present invention, the first optoelectronic device 13 and the second optoelectronic device 16 are simultaneously arranged, and the first optoelectronic device 13 and the second optoelectronic device 16 are respectively arranged corresponding to two sides of the lifting mechanism 101, so that the first time acquired by the first optoelectronic device 13 and the second time acquired by the second optoelectronic device 16 are respectively compared, and are also respectively compared with the preset time, thereby not only determining whether the lifting mechanism 101 extends out of place, but also determining whether the lifting mechanism 101 extends out of place, deflects or the like, and further improving the detection accuracy of the lifting mechanism 101.
