The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "or / and" used herein includes any and all combinations of one or more related listed items.
[0055] Some embodiments of the present disclosure are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.
[0056] Example
[0057] See also Figure 1 The skin treatment device 200, such as a hair removal device, a skin rejuvenation device, a hair growth device, etc., can achieve effects such as hair removal, skin rejuvenation, hair growth, whitening, freckle removal, and wrinkle removal by emitting appropriate treatment light (such as light of a special wavelength or different types of light) to act on the skin.
[0058] The general method of using the skin treatment device 200 is to turn on the skin treatment device 200 and put the light emitting surface P1 of the skin treatment device 200 on the skin. After the contact time reaches the trigger time, the skin treatment device 200 is triggered to emit treatment light to perform light treatment on the skin. If necessary, the same area of the skin can be lighted multiple times, or after one light treatment is completed, the skin treatment device 200 can be moved to the next area of the skin to be treated to perform the next light treatment on the new area.
[0059] It should be noted that, for a specific skin treatment device 200, the trigger time may be an inherent parameter thereof, and may be a fixed value or a variable value that can be adjusted as needed.
[0060] Figure 2 and Figure 3 A skin treatment device lighting test device 100 (hereinafter referred to as the lighting test device 100) of this embodiment is shown, wherein Figure 3 The skin treatment device 200 is additionally shown in dashed lines.
[0061] The lighting test device 100 provided in this embodiment is used to test whether the skin treatment device 200 can normally implement the lighting processing function. For example, the lighting test device 100 is used to perform lighting tests on the skin treatment device before delivery and during maintenance.
[0062] See also Figure 2 and Figure 3The lighting test device 100 includes a fixing component 10 , a driving component 20 , a target component 30 and a buffer component 40 .
[0063] The fixing assembly 10 is used to install the skin treatment device 200. For example Figure 2 and Figure 3 As shown in FIG. 1 , the fixing assembly 10 is a bench vise having a clamping opening K1. The skin treatment device 200 can be conveniently fixed and clamped at the clamping opening K1 of the bench vise. After the test is completed, the bench vise can be released to remove the skin treatment device 200. Optionally, flexible pads can be provided on both sides of the clamping opening K1 of the bench vise to avoid pinching the skin treatment device 200.
[0064] The target part 30 is used as an object of the lightening treatment by the skin treatment device 200 to receive the lightening treatment instead of the skin.
[0065] The material or shape of the target part 30 can be set as needed, and it only needs to be able to trigger the skin treatment device 200 to emit light after contacting the light-emitting surface P1 of the skin treatment device 200 for a triggering time, just like the skin. For example, in this embodiment, the target part 30 is a sheet-like part, such as a copper foil. When the skin treatment device 200 shines on the copper foil, it will leave a mark on the copper foil, and the mark can be reflected as a color change on the copper foil visible to the naked eye. In this way, by observing whether there is a mark of color change on the copper foil after the test, it can be judged whether the skin treatment device 200 has been normally illuminated.
[0066] In other embodiments, the target part 30 may also be a material that can leave a groove or undergo other detectable property changes after polishing, which is not limited here.
[0067] The driving assembly 20 is connected to the target member 30 for driving the target member 30 to move relative to the skin treatment device 200 so as to contact or separate from the skin treatment device 200. The buffer member 40 is disposed between the driving assembly 20 and the target member 30 for providing a buffer for the contact between the skin treatment device 200 and the target member 30.
[0068] Optionally, the driving assembly 20 is a reciprocating driving assembly, and in each reciprocating cycle of the driving assembly 20, the contact time between the skin treatment device 200 and the target part 30 is greater than or equal to the trigger time.
[0069] For example, the driving component 20 is a linear driving component, which is used to drive the skin treatment device 200 and the target part 30 to move relative to each other along a straight line. The target part 30 is a sheet-like part (such as copper foil) perpendicular to the relative displacement direction X between the skin treatment device 200 and the target part 30, which can be deformed to a certain extent under force.
[0070] When the lighting test device 100 in this embodiment is used, in each reciprocating cycle, the driving assembly 20 drives the buffer member 40 and the target member 30 to approach and contact the light-emitting surface P1 of the skin treatment device 200 along the displacement direction X, and then displace in a direction away from the skin treatment device 200 to separate from the light-emitting surface P1 of the skin treatment device 200.
[0071] The buffer 40 may be a block structure made of a flexible material (such as rubber, silicone, etc.). Due to the existence of the buffer 40, the target part 30 can maintain contact with the light-emitting surface P1 of the skin treatment device 200 for a period of time in each reciprocating cycle. In practice, the buffer 40 may be made to have a sufficient thickness and compression distance to ensure that the contact time between the target part 30 and the light-emitting surface P1 reaches the set trigger time in each reciprocating cycle.
[0072] In other embodiments, the buffer member 40 may also be other structures capable of elastic deformation, such as a coil spring, a leaf spring, etc., which is not limited here.
[0073] For a skin treatment device 200 with normal lighting function, it will perform lighting treatment on the target part 30 once in each reciprocating cycle. However, for a skin treatment device 200 with lighting problem, there may be situations of missing lighting, over-lighting, or lighting in the air (i.e., the skin treatment device 200 performs lighting when it is not in contact with the target part 30). Therefore, by observing the lighting test process or the lighting test results by the test personnel, or recording the number of lighting times by tools such as a lighting counter, it can be determined whether the lighting function of the skin treatment device 200 is normal, which is convenient and efficient to use and saves labor costs.
[0074] Continue to see Figure 2 and Figure 3 In this embodiment, the driving assembly 20 is connected to the buffer 40 in a transmission manner, and the target member 30 is connected to the side of the buffer 40 away from the driving assembly 20 and corresponds to the skin treatment device 200. Optionally, an exemplary driving assembly 20 includes a bracket 21, a rotating motor 22, a guide block 23, a connecting rod 24, a sliding rod 25, a turntable 26 and a top plate 27. The guide block 23 is fixedly connected to the bracket 21, and the sliding rod 25 is slidably matched with the guide block 23. The rotating motor 22 is installed on the bracket 21 and is connected to the turntable 26 in a transmission manner, so as to drive the turntable 26 to rotate. One end of the connecting rod 24 is hingedly connected to the sliding rod 25, and the other end is hingedly connected to the turntable 26, so as to convert the rotation of the turntable 26 into the linear sliding of the sliding rod 25. The top plate 27 is connected to one end of the slide bar 25 away from the connecting rod 24, the buffer member 40 is connected to the side of the top plate 27 away from the slide bar 25, and the target member 30 is attached to the side surface of the buffer member 40 away from the top plate 27 and faces the light emitting surface P1 of the skin treatment device 200.
[0075] The driving assembly 20 can drive the top plate 27 to move back and forth linearly through the rotation of the rotary motor 22, thereby driving the buffer member 40 and the target member 30 to move back and forth relative to the skin treatment device 200 to perform a lighting test.
[0076] The driving assembly 20 may further include a controller 28, which is electrically connected to the rotary motor 22 and is used to control the speed of the rotary motor 22 to control the speed of the linear motion of the target member 30, thereby controlling the contact time between the target member 30 and the skin treatment device 200 in each reciprocating cycle.
[0077] In other embodiments, the linear drive of the drive assembly 20 may also be achieved by a linear motor, a linear cylinder or other linear drive structures, which are not limited here.
[0078] See again Figure 2 and Figure 3 The lighting test device 100 in this embodiment further includes a base plate 50 and a mounting plate 60. The fixing assembly 10 is mounted on the base plate 50, and the driving assembly 20 is mounted on the base plate 50 through the mounting plate 60. The mounting position of the mounting plate 60 on the base plate 50 is adjustable to facilitate adjustment of the relative positions of the driving assembly 20 and the fixing assembly 10.
[0079] Figure 4 A second lighting test device 100a of this embodiment is shown.
[0080] relatively Figure 2 and Figure 3 The lighting test device 100, Figure 4 The lighting test device 100a of the embodiment of the present invention swaps the installation positions of the target part 30 and the skin treatment device 200, that is, the target part 30 is fixed to the fixing component 10, and the skin treatment device 200 is connected to the driving component 20. When in use, the driving component 20 drives the skin treatment device 200 to approach the target part 30 or to move away from the target part 30.
[0081] Optionally, the fixing assembly 10 is a support table 10a, the buffer 40 is a block structure made of flexible material, and the buffer 40 is fixedly supported on the support table 10a. The target part 30 is fixedly connected to (eg, attached to) a side surface of the buffer 40 away from the support table 10a.
[0082] The driving assembly 20 is connected to the skin treatment device 200 for driving the skin treatment device 200 to move back and forth in a straight line toward or away from the target part 30 .
[0083] The drive assembly 20 may be configured as follows: Figure 2 and Figure 3The structure in may also adopt other linear drive structures, such as linear cylinders, linear motors, etc., which will not be described in detail here.
[0084] In some other embodiments, the target part 30 is a long sheet structure, and the driving component 20 can also be a multi-degree-of-freedom robotic arm, which can not only move in the direction close to or away from the target part 30, but also move along the length direction of the target part 30, so that the position of each lighting is located at a different position of the target part 30, so that it can be more convenient to detect whether each lighting is successful.
[0085] Figure 5 A third lighting test device 100b of this embodiment is shown.
[0086] See also Figure 5 In the lighting test device 100b, the buffer 40 is a spring 40b, the skin treatment device 200 is movably mounted on the fixing assembly 10, and the buffer 40 is elastically supported between the fixing assembly 10 and the skin treatment device 200. The driving assembly 20 is transmission-connected to the target member 30, and is used to drive the target member 30 to approach or move away from the skin treatment device 200.
[0087] The lighting test device 100b can also achieve buffer contact between the skin treatment device 200 and the target part 30 during the test by providing a spring 40b as a buffer part 40, ensuring that the two can be in contact for a certain period of time to meet the requirement of triggering the skin treatment device 200 to light.
[0088] Figure 6 and Figure 7 A fourth lighting test device 100c of this embodiment is shown.
[0089] See also Figure 6 and Figure 7 The lighting test device 100 c includes a driving component 20 , a test head 70 and a fixing component 10 .
[0090] The fixing assembly 10 is used to fix and install the skin treatment device 200. Optionally, the driving assembly 20 can be Figure 1 and Figure 2 The fixing component 10.
[0091] The test head 70 includes a support plate 71, a buffer 40 and a target part 30. The buffer 40 is overlapped on one side of the support plate 71; the target part 30 is overlapped on the side of the buffer 40 away from the support plate 71. The buffer 40 is block-shaped, and the target part 30 is copper foil paper, which covers the target part 30 and the support plate 71 and has a test area 72 overlapped on the surface of the side of the buffer 40 away from the support plate 71, and the test area 72 is used to contact the skin treatment device 200. In this embodiment, the integrated test head 70 can be conveniently installed on the drive assembly 20 for testing, and is easy to install and use.
[0092] The driving assembly 20 is connected to the support plate 71 of the test head 70 for driving the test head 70 to move back and forth, so that the target part 30 contacts and presses the skin treatment device 200, or separates from the skin treatment device 200.
[0093] Optionally, the driving assembly 20 is a linear reciprocating driving assembly, which is used to drive the test head 70 to perform linear reciprocating movement between the first position and the second position.
[0094] Wherein, in the first position, the skin treatment device 200 and the target part 30 are separated from each other;
[0095] In the second position, the skin treatment device 200 presses the target member 30 so that the target member 30 and the buffer member 40 are in a concave state (see Figure 8 ). The contact time between the skin treatment device 200 and the target part 30 is the time when the target part 30 moves from the position just contacting the skin treatment device 200 to Figure 8 The time taken for the second position is shown.
[0096] In this way, the lighting test device 100c in this embodiment can conveniently realize the lighting test of the skin treatment device 200 approaching or moving away from the target part 30, and through the concave of the target part 30 and the buffer part 40, it can be ensured that during the test, the contact time between the skin treatment device 200 and the target part 30 can reach the trigger time.
[0097] In summary of the above description, the lighting test devices 100, 100a, 100b, 100c of the present embodiment can conveniently and efficiently test the lighting function of the skin treatment device 200, with high testing efficiency and saving labor costs.
[0098] The above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it. Although the present disclosure is described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solution of the present disclosure can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present disclosure.
