Description

Technical Field

[0001] This application relates to the technical field of testing equipment. Specifically, this application relates to an automatic testing equipment for a lamp adjusting device. Background Art

[0002] In addition to the light-emitting device part of the lamp needing to meet the standard specifications, the adjusting device of the lamp also has corresponding quality standard specifications. During the design and production process of the lamp, it is necessary to conduct small-scale tests on the performance of various adjusting devices to meet the corresponding standards. For different types of adjusting devices, there are certain differences in the quality standard specifications, mainly reflected in different requirements for the number of operations that can be performed within the service life. For example, for lamps that need to be frequently adjusted, the corresponding adjusting device should meet the requirement that the number of operations that can be performed within the service life is at least 1500 times; for lamps that are occasionally adjusted, the corresponding adjusting device should meet the requirement that the number of operations that can be performed within the service life is at least 150 times; for lamps that are fixedly installed, the corresponding adjusting device should meet the requirement that the number of operations that can be performed within the service life is at least 45 times. It can be seen that for the usage requirements of different lamps and their adjusting devices, the test requirements for various types of lamp adjusting devices are quite different, and an intuitive and automatically controllable testing equipment is needed to meet the small-scale test requirements and reduce the burden on R & D engineers.

[0022] Figure 1 is a schematic structural diagram of an automatic test equipment for a lamp adjusting device provided by an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Embodiments of the present application will be described below with reference to the accompanying drawings in the present application. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions of the embodiments of the present application.

[0024] Those skilled in the art of the present technology can understand that unless specifically stated, the terms "the" and "this" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of the present application means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence of other features, information, data, steps, operations, elements, components, and / or combinations thereof supported by the art of the present technology. The term "and / or" used herein means at least one of the items defined by the term, for example, "A and / or B" can be implemented as "A", or implemented as "B", or implemented as "A and B".

[0025] To make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0026] Referring to Figure 1 , the automatic test equipment for the lamp adjusting device of the present application includes a chassis 1, a motor, a visual test area 2, and a control area 3, and is used to implement the automatic test of the lamp adjusting device. According to the definition of the national standard, the adjusting device of the lamp includes structures such as movable joints, lifting devices, adjusting brackets, or telescopic tubes. The common feature of these adjusting devices is that the two components connected by the adjusting device can achieve relative movement under the active adjustment of the adjusting device. The effects of the relative movement include changes in angle, changes in distance, and comprehensive changes in angle and distance. The automatic test equipment provided by the present application can achieve the periodic operation test and visual test required by the national standard.

[0027] The chassis 1 provides a physical space for the automatic test equipment of the lamp adjusting device of the present application. The inside of the chassis 1 is provided with a motor, a motor drive system, and a motor control system to prevent these components from being exposed and affecting the performance of long-term use. The front surface of the chassis 1 is used as the observation surface. On the side wall 11 of the front surface of the chassis 1, a device for fixing the lamp adjusting device is configured to implement the test, and thus this area is defined as the visual test area 2. The top surface of the chassis 1 is used as the control area 3, and various controllers meeting the requirements of the national standard are provided in the control area 3. Preferably, universal wheels 13 can also be provided at the bottom of the chassis 1 to facilitate movement.

[0028] The visual test area 2 includes a clamping device 21 and a turntable 22. The clamping device 21 serves as the fixed end and the turntable 22 serves as the movable end, which are respectively used to fix the relatively movable components in the lamp adjusting device. When the visual test area 2 is in use, one end clamped by the clamping device 21 remains stationary, and the end clamped by the turntable 22 can rotate at a specified angle, translate a specified distance, or perform a combined motion, thereby simulating the actual use of the lamp.

[0029] In a possible implementation, the clamping device 21 includes a pair of clamping plates 211. One end of the lamp adjusting device is clamped between the pair of clamping plates 211 for fixation. In this embodiment, a distal fixed clamp 212 and a proximal fixed clamp 213 are provided on the pair of clamping plates 211. The distal fixed clamp 212 is used to fix the pair of clamping plates 211 to the side wall 12 on the side of the chassis 1. Further, the distal fixed clamp 212 can adjust the distance between the two clamping plates 211 to adapt to clamping different lamp adjusting devices. The side wall of the chassis 1 where the distal fixed clamp 212 is provided is preferably the side surface adjacent to the front surface of the chassis 1, that is, the left side surface or the right side surface. Further, the distal fixed clamp 212 includes a positioning member and a guiding member perpendicular to the axis of the clamping plate 211 and provided on the side wall of the chassis 1. The positioning member passes through the guiding member and is connected to the end of the clamping plate 211. Thus, the positioning member can translate within the guiding structure of the guiding member to adjust the distance between the two clamping plates 211. The distance between the positioning member and the end of the clamping plate 211 can also be adjusted, thereby adjusting the protruding length of the free end of the clamping plate 211. Optionally, the positioning member is a bolt or a screw rod, and the guiding member is a waist-shaped hole plate or a toothed hole plate. The proximal fixed clamp 213 is used to further clamp the free ends of the pair of clamping plates 211 to fix the object to be clamped, and can be provided within the range from the middle section to the vicinity of the free end of the pair of clamping plates 211. In this embodiment, the proximal fixed clamp 213 can adopt an adjustable distance component passing through the pair of clamping plates 211. Specifically, it can be a bolt passing through the pair of clamping plates 211 and a nut sleeved at the end of the bolt. For the convenience of visual observation, the pair of clamping plates 211 are arranged parallel to the observation surface, that is, the plane where the pair of clamping plates 211 are located is parallel to the front surface of the chassis 1.

[0030] The turntable 22 includes a fixture 221 located at the center of the turntable 22 and a turntable scale 222. The turntable scale 222 also faces the observation surface for easy visual observation. The turntable scale 222 uses angles as the main scale unit, and the minimum scale value can be set according to the test requirements. It is appropriate to set the minimum scale value within the range of 5° to 30°. The adjacent scale areas can be filled with colors having significant color differences or patterns with significant distinctions for differentiation, improving the convenience of visual testing. The fixture 221 is driven by a motor inside the chassis 1 to rotate or translate, so as to realize the test of the clamped lamp adjusting device. The implementation manner of the fixture 221 is not specially limited in this application, and any fixture 221 structure known to those skilled in the art that can achieve the test purpose is applicable. The movement modes of the fixture 221 driven by the motor include, but are not limited to: rotating around the center of the turntable 22 as a pivot at a specified angle, and the rotation direction can be clockwise or counterclockwise; starting from the center of the turntable 22, translating along the radial direction towards the clamping device 21, or translating in the radial direction towards other directions; the rotational and translational movement states of the fixture 221 can be combined.

[0031] Further, the motor is controlled by the test parameters that can be controlled by the control area 3. In this embodiment, the control area 3 is provided with an angle adjustment controller 31, a speed adjustment controller 32, a counter 33, and a switch control 34, and also includes a power switch. The working principle of the angle adjustment controller 31 is mainly to drive the internal actuator by receiving external signals, such as electrical signals or mechanical signals, so as to achieve precise angle adjustment. Before the actuator operates, the starting value of the rotation angle can be set through the relevant controls (buttons or knobs) set in the control area 3. The working principle of the speed adjustment controller 32 is to control the speed of the motor by changing the voltage or current supplied to the motor. The working principle of the counter 33 is to achieve the counting and processing of input signals through the state conversion of flip-flops and the operation of logic gates, and is usually used to measure, control, and record the frequency or quantity of specific events; the counter 33 can implement different counting modes, such as forward counting (gradually increasing from 0), reverse counting (gradually decreasing from the maximum value), and cyclic counting (continuing to start from 0 or another value after reaching the maximum value), and these counting modes can be achieved by controlling the connection mode of logic gates and flip-flops. The aforementioned angle adjustment controller 31, speed adjustment controller 32, counter 33, and switch control 34 can be set in the form of application software. Thus, a reserved slot 35 for installing a touch screen can be provided in the control area 3. As an interactive hardware, the processor of the touch screen loads the application software of the automatic test equipment for controlling the entire lamp adjusting device.

[0032] The test requirements are to set the operating cycle of the lamp adjusting device. An operating cycle is defined as moving from one end to the other end within the adjustment range and then back to the starting position, and the moving speed should not cause the device to heat up significantly, not exceeding 600 cycles per hour. The automatic test equipment for the lamp adjusting device of the present application can well set the movement trajectory, movement mode, movement speed and cycle count in the operating cycle, enabling the tester to focus on visually observing the movement changes of the lamp adjusting device in the visual test area 2. Taking the adjusting rod of the lamp as an example, the usage process of the lamp adjusting device of the present application is further described.

[0033] This embodiment adopts an adjusting rod of a lamp with the following structure: the adjusting rod includes at least two adjusting limbs, and adjacent two adjusting limbs are pivotally connected by a connecting structure, so that the two adjusting limbs can rotate coplanarly around the connecting structure. When using the automatic test equipment for the lamp adjusting device of the present application to perform an operating cycle test on this adjusting rod, it is determined that this adjusting rod belongs to the object that needs to be "frequently adjusted" for the test object, and thus the number of operating cycles to be executed during the test is set. A possible implementation of the movement mode of the fixture 221 in a single operating cycle is to set the number of operating cycles to 100 times, and the fixture 221 reciprocally rotates around the center of the turntable 22 to simulate the usage scenario. The rotation angle range is 0~180°, covering the rotation range of the adjusting rod, and the rotation speed is appropriate and does not cause the adjusting rod to heat up. These parameters can be set through various controllers on the control area 3. Further, fix the adjusting rod in the visual test area 2, fix one of the adjusting limbs through the clamping device 21, and the distal fixed clamp 212 and the proximal fixed clamp 213 of the clamping device 21 jointly coordinate to properly clamp the free end of the adjusting limb; the other adjusting limb is fixed through the fixture 221 of the turntable 22, and the fixture 221 is controlled to reciprocally rotate around the center of the turntable 22 according to the test parameters set through the control area 3 as described above. Each time an operating cycle is completed, it is counted once until the specified number of all operating cycles is completed. Before the counting of the number of operating cycles is completed, it is the time window for the tester to visually observe the activity state of the adjusting rod.

[0034] In summary, the automatic test equipment for the lamp adjusting device includes: a chassis and a motor inside it, a visual test area for observing the test process of the lamp adjusting device, located on the front side wall of the chassis; a control area for setting the test parameters of the lamp adjusting device, located on the top surface of the chassis. The automatic test equipment for the lamp adjusting device of the present application sets the visual test area on the front side wall of the chassis, which is more conducive to engineers observing during the test process, and it is also convenient to assemble the lamp adjusting device between the clamping plate and the fixture, and small-scale tests of various different lamp adjusting devices can be realized through simple operations without cumbersome test equipment, meeting the R & D requirements.
