Detailed Implementation

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0027] It should be noted that the laser needs to undergo aging tests. Taking a certain fiber laser as an example, it needs to be connected to the collimator via a QBH connector, and then the laser's three-axis position needs to be adjusted to achieve alignment. After positioning and installation, the laser maintains full-power output for a long period. The fiber laser and collimator are only connected by checking whether the contact points are short-circuited to determine whether the laser is installed correctly, and thus whether laser output is allowed.

[0028] Specifically, two electrical connection contact points are provided on the outer wall of the fiber laser and two on the inner wall of the collimator. When the fiber laser is not installed in the collimator, the two contact points of the collimator remain electrically connected. When the fiber laser is installed in the collimator, the two contact points of the collimator are short-circuited. Based on the change in resistance from infinity to zero before and after contact, it is determined that the laser is installed correctly, and power can then be supplied to the laser.

[0029] Laser testing is often conducted without appropriate safety fixtures, or in relatively harsh environments (cutting and cleaning metal can easily generate metal dust, which can short-circuit contact points, leading to misjudgments and unexpected laser emission). For example, before and after laser aging tests, if personnel fail to check the laser's power supply and remove the QBH laser without disconnecting it, and the laser lacks safety fixtures, it may still be powered on and continue emitting light, easily damaging surrounding testing equipment or even injuring personnel, resulting in poor safety and reliability.

[0030] To solve the above problems, refer to Figure 1 and Figure 2 As shown, this utility model embodiment provides a laser positioning installation device, including a fixing sleeve 10, a laser output head 30, a first adjuster 40, and a controller 50.

[0031] The fixing sleeve 10 is hollow along the axial direction to accommodate the laser output head 30. Preferably, the fixing sleeve 10 is configured as a laser collimator.

[0032] The inner wall of the fixing sleeve 10 is provided with a first electrical connection part 11 and a second electrical connection part 12. The first electrical connection part 11 and the second electrical connection part 12 can be electrical connection contacts, electrical connection contact strips or other components for electrical connection.

[0033] Preferably, the first electrical connection part 11 and the second electrical connection part 12 are arranged sequentially along the axial direction of the fixing sleeve 10.

[0034] The first electrical connection portion 11 is configured to be electrically connected to the first pole 21 of the first power supply 20, and the second electrical connection portion 12 is configured to be electrically connected to the second pole 22 of the first power supply 20. The first pole 21 of the first power supply 20 can be either the positive or negative pole of the first power supply 20, while the second pole 22 is the other pole of the first power supply 20 with the opposite polarity to the first pole 21.

[0035] In this embodiment of the invention, the first power supply 20 is mainly used for positioning, installation, and detection of the fixing sleeve 10 and the laser output head 30, while the power supply for the laser output head 30 is handled by another power supply. For example, a second power supply 80 is provided for the laser output head 30. Of course, the laser output head 30 can also be powered by the first power supply 20.

[0036] The laser output head 30 is preferably a fiber laser. The laser output head 30 is detachably disposed within the retaining sleeve 10. Preferably, the retaining sleeve 10 and the laser output head 30 are snap-fit ​​connected, for example, through a QBH connector to achieve a detachable connection. In some other embodiments, threaded connections or other connection methods may also be selected.

[0037] A third electrical connection part 31 and a fourth electrical connection part 32 are provided on the outer wall of the laser output head 30. The third electrical connection part 31 and the fourth electrical connection part 32 can be electrical connection contact points, electrical connection contact strips or other components for electrical connection.

[0038] The third electrical connection 31 and the fourth electrical connection 32 are electrically connected. For example, both the third electrical connection 31 and the fourth electrical connection 32 are configured as electrical connection rings, and the laser output head 30 also has a conductive post 35 inside, which connects to the two electrical connection rings respectively, thereby achieving electrical connection. It can be understood that the third electrical connection 31, the fourth electrical connection 32, and the conductive post 35 can be considered as a single wire.

[0039] Preferably, the third electrical connection portion 31 and the fourth electrical connection portion 32 are arranged sequentially along the axial direction of the laser output head 30.

[0040] When the laser output head 30 is installed in the fixing sleeve 10, the third electrical connection part 31 of the laser output head 30 is electrically connected to the first electrical connection part 11 of the fixing sleeve 10, and the fourth electrical connection part 32 of the laser output head 30 is electrically connected to the second electrical connection part 12 of the fixing sleeve 10, so that the circuit forms a loop.

[0041] After the laser output head 30 is removed from the fixing sleeve 10, the third electrical connection 31 is disconnected from the first electrical connection 11, the fourth electrical connection 32 and the second electrical connection 12 are disconnected, and the corresponding circuit is broken.

[0042] When the laser output head 30 is subjected to aging test, it needs to be aligned and positioned with the receiving position of a laser test device. The first adjuster 40 is used for single-axis positioning of the laser output head 30.

[0043] Specifically, the first regulator 40 includes a first adjusting member 41 and a first rheostat 42. The first adjusting member 41 is connected to the fixed sleeve 10, and for example, the two are fixedly connected by an adapter 100.

[0044] Specifically, the adapter 100 includes a first connecting component and a second connecting component, which are connected at an angle, preferably 90°. The first connecting component is bolted to the first adjusting component 41, and the second connecting component is bolted to the fixing sleeve 10.

[0045] The first adjusting member 41 is configured to move along a first direction, thereby achieving single-axis positioning of the fixed sleeve 10 and the laser output head 30.

[0046] For example, the first adjusting member 41 includes a slide rail, a slider, and a micrometer adjuster. The extension direction of the slide rail is parallel to the first direction, the slider is slidably connected to the slide rail, and the fixing sleeve 10 is disposed on the slider. When it is necessary to position and adjust the laser output head 30, the slider is finely adjusted by the micrometer adjuster, so that the slider slides relative to the slide rail. In turn, the slider drives the fixing sleeve 10 and the laser output head 30 to move along the first direction, so that the light emitted by the laser output head 30 is aligned with the receiving position of the laser testing equipment. In some other embodiments, a similar effect can also be achieved by using a threaded guide sleeve and a lead screw.

[0047] The first rheostat 42 is disposed in the circuit between the second electrical connection part 12 and the second pole 22, and the first resistance value of the first rheostat 42 is adjusted as the first adjusting member 41 moves.

[0048] For example, the first rheostat 42 can be configured as a sliding rheostat, a linear potentiometer, etc. Taking a sliding rheostat as an example, it includes a resistance wire disposed on a terminal and a slider that can slide relative to the resistance wire. In order to adjust the first resistance value as the first adjusting member 41 moves, one axial end of the resistance wire can be electrically connected to the second electrical connection part 12, and the slider can be electrically connected to the second pole 22 of the first power supply 20. At the same time, the slider is fixedly connected to the resistance wire or the slider. When the slider moves, the slider drives the corresponding component to move, thereby adjusting the first resistance value.

[0049] The first direction can be arbitrarily set according to actual needs, such as parallel to the X-axis, parallel to the Y-axis, parallel to the Z-axis, etc. Specifically, the first direction can be the axial direction, the width direction, or the thickness direction of the fixed sleeve 10.

[0050] The controller 50 is configured to switch the laser output head 30 on and off according to the magnitude of the first resistance value of the first rheostat 42.

[0051] For example, after the laser output head 30 is positioned uniaxially in the first direction using the first adjusting member 41, a corresponding first resistance value can be obtained. This first resistance value corresponds to the position of the laser output head 30 in the first direction when it is aligned. The controller 50 detects and records the first resistance value when the laser output head 30 is aligned, and then controls the power supply to the laser output head 30 during subsequent testing. It should be noted that this recorded value can be a fixed value or a resistance range.

[0052] If the laser output head 30 is not installed in the fixing sleeve 10, the circuit is short-circuited, the first resistance value cannot be detected, and the power to the laser output head 30 is cut off. If the laser output head 30 is installed in the fixing sleeve 10, but the first adjusting member 41 is not in place, that is, the laser of the laser output head 30 is not aligned with the receiving position of the laser testing equipment, although the first resistance value can be detected, the first resistance value does not match the previously recorded value, so the power to the laser output head 30 is also cut off.

[0053] The controller 50 can be a PCB board. The processing and comparison components in the PCB board analyze whether the measured resistance value meets the conditions. When the resistance value meets the standard, the PCB board outputs a high-level signal, thereby closing the switch in the power supply circuit and powering the circuit. When the resistance value does not meet the standard, the PCB board outputs a low-level signal, thereby opening the switch in the power supply circuit and powering the circuit off.

[0054] The controller 50 mentioned above can also be multiple switches connected in series on the power supply circuit of the laser output head 30 to form an AND gate circuit; when the resistance value meets the condition, all switches are closed and the circuit is powered on; when the resistance value does not meet the condition, the switches are open and the circuit is powered off.

[0055] In some other embodiments, additional components such as buzzers and alarm lights may be provided to issue warnings.

[0056] The laser positioning and installation device of this utility model has corresponding electrical connection parts between the fixing sleeve 10 and the laser output head 30. When the laser output head 30 is installed on the fixing sleeve 10, the electrical connection parts are electrically connected, thus connecting the circuit. When the first adjusting member 41 adjusts the positioning of the laser output head 30, it simultaneously adjusts the first resistance value of the first rheostat. The controller 50 detects whether the first resistance value meets the requirements, thereby controlling the power supply to and from the laser output head 30. In this way, the safety and reliability of laser positioning and installation can be effectively improved, preventing accidental laser emission, ensuring safe testing, and ensuring the safety of personnel and other instruments.

[0057] Reference Figure 4 As shown, in some embodiments of the laser positioning and installation device of this utility model, a fifth electrical connection part 13 is further provided within the fixing sleeve 10. The fifth electrical connection part 13 is configured to be electrically connected to the second pole 22. The fifth electrical connection part 13 can be an electrical connection contact point, an electrical connection contact strip, or other components for electrical connection.

[0058] Preferably, the first electrical connection part 11, the second electrical connection part 12 and the fifth electrical connection part 13 are arranged sequentially along the axial direction of the fixing sleeve 10.

[0059] A sixth electrical connection portion 33 is also provided on the outer wall of the laser output head 30. The sixth electrical connection portion 33 is connected to the third electrical connection portion 31. Preferably, the connection between the sixth electrical connection portion 33 and the third electrical connection portion 31 is achieved through a conductive post 35. The sixth electrical connection portion 33 can be an electrical contact point, an electrical contact strip, or other components for electrical connection.

[0060] Preferably, the third electrical connection part 31, the fourth electrical connection part 32 and the sixth electrical connection part 33 are arranged sequentially along the axial direction of the laser output head 30.

[0061] When the laser output head 30 is installed in the fixed sleeve 10, the sixth electrical connection part 33 of the laser output head 30 is electrically connected to the fifth electrical connection part 13 of the fixed sleeve 10, and at the same time, the first electrical connection part 11 and the third electrical connection part 31 are electrically connected, so that the circuit forms a loop.

[0062] After the laser output head 30 is removed from the fixing sleeve 10, the third electrical connection 31 is disconnected from the first electrical connection 11, the sixth electrical connection 33 and the fifth electrical connection 13 are disconnected, and the corresponding circuit is broken.

[0063] The laser positioning installation device also includes a second adjuster 60, which is used for positioning the fixed sleeve 10 in a second direction.

[0064] Specifically, the second adjuster 60 includes a second adjusting member 61 and a second rheostat 62, with the second adjusting member 61 connected to the first adjusting member 41. The second adjusting member 61 is configured to move along a second direction, thereby achieving single-axis positioning of the fixed sleeve 10 and the laser output head 30 in the second direction. Preferably, the second direction is perpendicular to the first direction. Those skilled in the art can configure the second adjusting member 61 according to actual needs, such as a combination of slide rail and slider, a combination of guide sleeve and lead screw, etc.

[0065] The second rheostat 62 is disposed in the circuit between the second pole 22 and the fifth electrical connection portion 13, and the second resistance value of the second rheostat 62 is adjusted as the second regulator 60 moves. For example, the second rheostat 62 can be configured as a sliding rheostat, a linear potentiometer, etc. The second rheostat 62 is connected in parallel with the first rheostat 42.

[0066] After the laser output head 30 is positioned in a single axis in the second direction by the second regulator 60, a corresponding second resistance value can be obtained. At this time, the second resistance value corresponds to the position in the second direction when the laser output head 30 is aligned. The controller 50 detects and records the second resistance value when the laser output head 30 is aligned, and then controls the power supply to the laser output head 30 during subsequent testing.

[0067] If the laser output head 30 is not installed in the fixing sleeve 10, the circuit is short-circuited, the second resistance value cannot be detected, and the power to the laser output head 30 is cut off. If the laser output head 30 is installed in the fixing sleeve 10, but the second adjusting member 61 is not in place, meaning the laser from the laser output head 30 is not aligned with the receiving position of the laser testing equipment, although the second resistance value can be detected, it does not match the previously recorded value, so the power to the laser output head 30 is also cut off. Of course, the first resistance value also needs to be considered in this case, which will not be elaborated further.

[0068] In this way, the positioning requirements of the laser output head 30 can be met, ensuring the precise positioning of the laser output head 30 in the first and second directions, thereby effectively ensuring the reliability and safety of the device during the aging test.

[0069] Reference Figure 4 As shown, in some embodiments of the laser positioning and installation device of this utility model, a seventh electrical connection part 14 is further provided within the fixing sleeve 10. The seventh electrical connection part 14 is configured to be electrically connected to the second pole 22. The seventh electrical connection part 14 can be an electrical connection contact point, an electrical connection contact strip, or other components for electrical connection.

[0070] Preferably, the first electrical connection part 11, the second electrical connection part 12, the fifth electrical connection part 13 and the seventh electrical connection part 14 are arranged sequentially along the axial direction of the fixing sleeve 10.

[0071] An eighth electrical connection portion 34 is also provided on the outer wall of the laser output head 30. The eighth electrical connection portion 34 is connected to the third electrical connection portion 31. Preferably, the connection between the eighth electrical connection portion 34 and the third electrical connection portion 31 is achieved through a conductive post 35. The eighth electrical connection portion 34 can be an electrical contact point, an electrical contact strip, or other components for electrical connection.

[0072] Preferably, the third electrical connection part 31, the fourth electrical connection part 32, the sixth electrical connection part 33 and the eighth electrical connection part 34 are arranged sequentially along the axial direction of the laser output head 30.

[0073] When the laser output head 30 is installed in the fixed sleeve 10, the eighth electrical connection part 34 of the laser output head 30 is electrically connected to the seventh electrical connection part 14 of the fixed sleeve 10, and at the same time, the first electrical connection part 11 and the third electrical connection part 31 are electrically connected, so that the circuit forms a loop.

[0074] After the laser output head 30 is removed from the fixing sleeve 10, the third electrical connection 31 is disconnected from the first electrical connection 11, the eighth electrical connection 34 and the seventh electrical connection 14 are disconnected, and the corresponding circuits are broken.

[0075] The laser positioning installation device also includes a third adjuster 70, which is used for the third-direction positioning of the fixed sleeve 10.

[0076] Specifically, the third adjuster 70 includes a third adjusting member 71 and a third rheostat 72. The third adjusting member 71 is connected to the second adjusting member 61. The third adjusting member 71 is configured to move along a third direction, thereby achieving single-axis positioning of the fixed sleeve 10 and the laser output head 30 in the third direction. Preferably, the third direction is perpendicular to the first direction and the second direction, respectively. Those skilled in the art can configure the third adjusting member 71 according to actual needs, such as a combination of slide rail and slider, a combination of guide sleeve and lead screw, etc.

[0077] The third rheostat 72 is disposed in the circuit between the second electrode 22 and the seventh electrical connection 14, and the third resistance value of the third rheostat 72 is adjusted as the third adjusting member 71 moves. For example, the third rheostat 72 can be configured as a sliding rheostat, a linear potentiometer, etc. The third rheostat 72 is connected in parallel with the first rheostat 42, and the third rheostat 72 is connected in parallel with the second rheostat 62.

[0078] After the laser output head 30 is positioned in a third direction using the third regulator 70, a corresponding third resistance value is obtained. This third resistance value corresponds to the third-direction position of the laser output head 30 when it is aligned. The controller 50 detects and records the third resistance value of the laser output head 30 when it is aligned, and then controls the power supply to the laser output head 30 during subsequent testing.

[0079] If the laser output head 30 is not installed in the fixing sleeve 10, the circuit is short-circuited, the third resistance value cannot be detected, and the power to the laser output head 30 is cut off. If the laser output head 30 is installed in the fixing sleeve 10, but the third adjustment component 71 is not in place, meaning the laser from the laser output head 30 is not aligned with the receiving position of the laser testing equipment, although the third resistance value can be detected, it does not match the previously recorded value, so the power to the laser output head 30 is also cut off. Of course, the first and second resistance values ​​also need to be considered in this case, but these will not be elaborated further.

[0080] In this way, the positioning requirements of the laser output head 30 can be met, ensuring the precise positioning of the laser output head 30 in the first, second, and third directions, thereby effectively ensuring the reliability and safety of the device during the aging test.

[0081] Reference Figure 5 As shown, in some embodiments of the laser positioning and installation device of this utility model, the controller 50 includes a first comparison component 51, a second comparison component 52, a third comparison component 53, and a control component 54.

[0082] The first comparison component 51 is used to compare the first target value with the first resistance value of the first rheostat 42. For example, the positioning and adjustment can be pre-implemented using the first adjustment component 41, and then the corresponding first resistance value can be recorded and used as the first target value. It should be noted that the first target value can be a fixed value or a resistance range.

[0083] When the first comparison component 51 compares the resistance values, there are two possible results. The first is that the first target value matches the first resistance value, indicating that in the first direction, the first adjustment component 41 has moved the laser output head 30 into position. The second is that the first target value does not match the first resistance value, including the first target value being less than or greater than the first resistance value, indicating that in the first direction, the laser output head 30 has not moved into position, or the laser output head 30 is not correctly installed. Matching the first target value with the first resistance value is taken as the first condition.

[0084] The second comparison component 52 is used to compare the second target value with the second resistance value of the second rheostat 62. For example, the positioning and adjustment can be pre-implemented using the second adjustment component 61, and then the corresponding second resistance value can be recorded and used as the second target value. It should be noted that the second target value can be a fixed value or a resistance range.

[0085] When the second comparison component 52 compares the resistance values, there are two possible results. The first is that the second target value matches the second resistance value, indicating that in the second direction, the second adjustment component 61 has moved the laser output head 30 into position. The second is that the second target value does not match the second resistance value, including the second target value being less than or greater than the second resistance value, indicating that in the second direction, the laser output head 30 has not moved into position, or the laser output head 30 is not correctly installed. Matching the second target value with the second resistance value is taken as the second condition.

[0086] The third comparison unit 53 is used to compare the third target value with the third resistance value of the third rheostat 72. For example, the positioning and adjustment can be pre-implemented using the third adjustment unit 71, and then the corresponding third resistance value can be recorded and used as the third target value. It should be noted that the third target value can be a fixed value or a resistance range.

[0087] When the third comparison component 53 compares the resistance values, there are two possible results. The first is that the third target value matches the third resistance value, indicating that in the third direction, the third adjustment component 71 has moved the laser output head 30 into position. The second is that the third target value does not match the third resistance value, including the third target value being less than or greater than the third resistance value, indicating that in the third direction, the laser output head 30 has not moved into position, or the laser output head 30 is not correctly installed. Matching the third target value with the third resistance value is taken as the third condition.

[0088] Preferably, the control unit 54 is an STM32 chip. The control unit 54 is electrically connected to the first comparison unit 51, the second comparison unit 52 and the third comparison unit 53 respectively, and receives the comparison signals from the first comparison unit 51, the second comparison unit 52 and the third comparison unit 53, and sends control signals.

[0089] Specifically, the control unit 54 is configured to transmit a power-off signal if any one of the first, second, or third conditions is not met. This includes various scenarios: only the first condition is not met; only the second condition is not met; only the third condition is not met; neither the first nor the second condition is met; neither the first nor the third condition is met; neither the second nor the third condition is met; and none of the first, second, or third conditions are met. In these cases, the laser output head 30 is powered off.

[0090] Furthermore, the control unit 54 is configured to transmit a power-off signal to power on the laser output head 30 when the first condition, the second condition, and the third condition are met simultaneously, so that the laser output head 30 can emit light.

[0091] This effectively improves the reliability and safety of the device during the aging test.

[0092] Reference Figure 5 As shown, in some embodiments of the laser positioning and installation device of this utility model, the first rheostat 42 is configured as a sliding rheostat, which includes a first resistance bar 421 and a first slider 422. One end of the first resistance bar 421 along its own length direction is electrically connected to the second electrical connection part 12, while the first slider 422 is electrically connected to the first resistance bar 421 and the second electrode 22 respectively.

[0093] The first slider 422 is disposed on the first adjusting member 41 and moves synchronously with the first adjusting member 41. At the same time, the first slider 422 is slidable relative to the first resistance bar 421 along the length direction of the first resistance bar 421.

[0094] When the first adjusting member 41 is adjusted, the first slider 422 slides on the first resistance bar 421, and the first resistance value of the first rheostat 42 changes accordingly.

[0095] The second rheostat 62 is configured as a sliding rheostat, which includes a second resistance bar 621 and a second slider 622. One end of the second resistance bar 621 along its length is electrically connected to the fifth electrical connection part 13, while the second slider 622 is electrically connected to the second resistance bar 621 and the second electrode 22 respectively.

[0096] The second slider 622 is disposed on the second adjusting member 61 and moves synchronously with the second adjusting member 61. At the same time, the second slider 622 is slidable relative to the second resistance bar 621 along the length direction of the second resistance bar 621.

[0097] When the second adjusting member 61 is adjusted, the second slider 622 slides on the second resistance bar 621, and the second resistance value of the second resistor changes accordingly.

[0098] The third rheostat 72 is a sliding rheostat, which includes a third resistance bar 721 and a third slider 722. One end of the third resistance bar 721 along its length is electrically connected to the seventh electrical connection part 14, while the third slider 722 is electrically connected to the third resistance bar 721 and the third electrode respectively.

[0099] The third slider 722 is disposed on the third adjusting member 71 and moves synchronously with the third adjusting member 71. Along the length direction of the third resistance bar 721, the third slider 722 is slidable relative to the third resistance bar 721.

[0100] When the third adjusting member 71 is adjusted, the third slider 722 slides on the third resistance bar 721, and the third resistance value of the third resistor changes accordingly.

[0101] The first rheostat 42, the second rheostat 62, and the third rheostat 72 provide the required real-time resistance values ​​for the first comparison unit 51, the second comparison unit 52, and the third comparison unit 53. By determining whether the resistance values ​​provided by each rheostat meet the requirements, the control unit 54 sends an on or off signal to control the power supply circuit of the laser output head 30, effectively ensuring the reliability and safety of the device during testing.

[0102] Reference Figure 5 As shown, in some embodiments of the laser positioning and installation device of this utility model, in order to detect the resistance values ​​of the first rheostat 42, the second rheostat 62 and the third rheostat 72, a first resistance detection component 55, a second resistance detection component 56 and a third resistance detection component 57 are respectively provided in the controller 50.

[0103] The first resistance detection component 55 is electrically connected to the first rheostat 42 and the first comparison component 51 respectively. The first resistance detection component 55 is used to monitor the first resistance value of the first rheostat 42 and transmit the measured first resistance value to the first comparison component 51 for comparison.

[0104] The second resistance detection component 56 is electrically connected to the second rheostat 62 and the second comparison component 52 respectively. The second resistance detection component 56 is used to monitor the second resistance value of the second rheostat 62 and transmit the measured second resistance value to the second comparison component 52 for comparison.

[0105] The third resistance detection component 57 is electrically connected to the third rheostat 72 and the third comparison component 53 respectively. The third resistance detection component 57 is used to monitor the third resistance value of the third rheostat 72 and transmit the measured third resistance value to the third comparison component 53 for comparison.

[0106] The first resistance detection component 55, the second resistance detection component 56, and the third resistance detection component 57 can be ohmmeters, allowing direct detection of the resistance value of the rheostat without the need for indirect measurement. Alternatively, the first resistance detection component 55, the second resistance detection component 56, and the third resistance detection component 57 can be configured using the voltmeter-ammeter method, incorporating an ammeter, a voltmeter, and a resistance calculation component in the circuit to calculate the resistance value. Furthermore, the first resistance detection component 55, the second resistance detection component 56, and the third resistance detection component 57 can also be impedance analyzers for direct measurement of the rheostat's resistance value.

[0107] The configuration of the first resistance detection component 55, the second resistance detection component 56, and the third resistance detection component 57 enables accurate real-time detection of the resistance values ​​of the first rheostat 42, the second rheostat 62, and the third rheostat 72. By monitoring the first, second, and third resistance values ​​in real time and transmitting the data promptly to the first comparison component 51, the second comparison component 52, and the third comparison component 53, the control component 54 issues power-off or power-on signals based on the comparison results, thereby improving the safety and reliability of the aging test.

[0108] Reference Figure 3 and Figure 4 As shown, in some embodiments of the laser positioning and installation device of this utility model, the first electrical connection part 11, the second electrical connection part 12, the fifth electrical connection part 13 and the seventh electrical connection part 14 are set as electrical connection contact points, and the third electrical connection part 31, the fourth electrical connection part 32, the sixth electrical connection part 33 and the eighth electrical connection part 34 are set as electrical connection strips.

[0109] Compared to other electrical connection methods, the electrical connection strip increases the area for electrical connection with the electrical contact point, which can effectively reduce the installation angle requirements of the laser output head 30 during installation, and can improve work efficiency and installation error tolerance.

[0110] Reference Figure 4 As shown, in some embodiments of the laser positioning and installation device of this utility model, when the circumferential dimension of the laser output head 30 is L2, the length L1 of the electrical connecting strip ∈ [0.5*L2, L2], that is, the length of the electrical connecting strip should be less than or equal to the circumferential dimension L2 of the laser output head 30, but greater than or equal to half of the circumferential dimension L2 of the electrical connecting strip. It can be understood that when the length L1 of the electrical connecting strip is equal to the circumferential dimension L2 of the laser output head 30, the electrical connecting strip is an electrical connecting ring.

[0111] When the laser output head 30 is installed in the fixing sleeve 10, the longer electrical connecting strip allows for better electrical connection between the various electrical components. This effectively reduces the requirements for the installation angle and improves the ease of installation.

[0112] Reference Figure 5 As shown, in some embodiments of the laser positioning and installation device of this utility model, the laser output head 30 is powered separately. Specifically, the laser positioning and installation device includes a second power supply 80 and a control switch 90.

[0113] The second power supply 80 is electrically connected to the laser output head 30, providing a separate power supply for the laser output head 30. A control switch 90 is installed in the circuit between the second power supply 80 and the laser output head 30, used to control the on / off state of the circuit between the second power supply 80 and the laser output head 30.

[0114] The laser output head 30 is independently powered by a second power supply 80, and the control switch 90 is electrically connected to the control component 54 in the controller 50. When the first, second, and third conditions are simultaneously met, the control component 54 sends an energizing signal to the control switch 90, and the control switch 90 closes. At this time, the circuit between the second power supply 80 and the laser output head 30 is energized, and the laser output head 30 can emit light.

[0115] When any one of the first, second, or third conditions is not met, the control unit 54 sends a power-off signal to the control switch 90, and the control switch 90 is disconnected. At this time, the circuit between the second power supply 80 and the laser output head 30 is de-energized, and the laser output head 30 cannot emit light.

[0116] Utilizing a second power supply 80 and a control switch 90 to independently power the laser output head 30 improves power supply stability, avoids the impact of other circuit failures, and effectively enhances safety and stability. Controlling the control switch 90 via the control component 54 ensures that the circuit is powered off when all conditions are met simultaneously, effectively improving safety during aging tests and installation / use.

[0117] Working principle:

[0118] The laser output head 30 is inserted into the fixing sleeve 10 for installation. The first electrical connection part 11 is electrically connected to the third electrical connection part 31, the second electrical connection part 12 is electrically connected to the fourth electrical connection part 32, the fifth electrical connection part 13 is electrically connected to the sixth electrical connection part 33, and the seventh electrical connection part 14 is electrically connected to the eighth electrical connection part 34. The circuit where the first power supply 20 is located is thus turned on.

[0119] The first resistance detection unit 55, the second resistance detection unit 56, and the third resistance detection unit 57 respectively detect the first resistance value of the first rheostat 42, the second resistance value of the second rheostat 62, and the third resistance value of the third rheostat 72 in the circuit. The measured first resistance value, second resistance value, and third resistance value are transmitted to the first comparison unit 51, the second comparison unit 52, and the third comparison unit 53 of the controller 50, respectively, and the first comparison unit 51, the second comparison unit 52, and the third comparison unit 53 determine whether the first condition, the second condition, and the third condition are met, respectively.

[0120] When all three conditions are met, the control component 54 of the controller 50 sends a power-on signal, and the control switch 90 in the second power supply 80 circuit that provides independent power to the laser output head 30 is closed, and the second power supply 80 begins to supply power to the laser output head 30.

[0121] When any one of the three conditions is not met, the control component 54 of the controller 50 sends a power-off signal, the control switch 90 in the second power supply 80 circuit that provides independent power to the laser output head 30 is turned off, and the second power supply 80 stops supplying power to the laser output head 30.

[0122] At this point, it is necessary to check whether the laser output head 30 is installed correctly, and to adjust the position of the fixing sleeve 10 and the laser output head 30 using the first adjusting component 41, the second adjusting component 61, and the third adjusting component 71. The resistance values ​​of the corresponding rheostats are adjusted accordingly. When the resistance values ​​of all rheostats meet the conditions, the control component 54 of the controller 50 sends an energizing signal, closing the control switch 90 in the second power supply 80 circuit that provides independent power to the laser output head 30, and the second power supply 80 begins to supply power to the laser output head 30.

[0123] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0124] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0125] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
