[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the illumination detection device and ultraviolet curing equipment provided by the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] At present, in the process of LCD screen manufacturing, the LCD glass needs to be cured by ultraviolet curing equipment. Figure 1 and Figure 2 As shown, the ultraviolet curing device includes: a workbench 1 and an ultraviolet lamp 2 located above the workbench 1. The workbench 1 is a workspace for placing the liquid crystal glass to be cured. When in use, the liquid crystal glass to be cured is sent to the workspace by a manipulator, and the ultraviolet lamp 2 irradiates the liquid crystal glass in the workspace to achieve curing.

[0031] In the daily production process, the UV lamp 2 may be replaced. In order to ensure the curing effect of the liquid crystal glass, it is necessary to measure the overall original illumination value after each replacement to complete the initial setting of the illumination power of each UV lamp 2 source. Figure 1 and Figure 2As shown, the measurement method in the prior art is to manually place a special measuring jig 3 in the working space of the workbench 1 and adjust it to just below the ultraviolet light source. Since multiple ultraviolet light sources are required in the production process, a special measuring jig 3 needs to be set under each ultraviolet light source for measurement, and the jig 3 needs to be removed after the measurement. Not only does the process of adjusting the position take a long time, but it also needs to manually record the measurement data and transcribe it into the computer, which is not only time-consuming and labor-intensive, but also prone to errors. Moreover, when the jig 3 is placed on the workbench 1, it occupies the working space of the workbench 1, that is, the position of the liquid crystal glass that needs to be cured. Therefore, after the measurement, the jig 3 needs to be taken down again. In the process of taking and placing the jig 3, it is also easy for the jig 3 to collide with the workbench 1, causing damage to the jig 3 or the workbench 1.

[0032] In order to solve the above problems, Figure 3 and Figure 4 As shown, an embodiment of the utility model discloses a light intensity detection device for the light intensity of a working space, wherein the light source in the working space can be an ultraviolet light source, a visible light source or an infrared light source, etc. In this embodiment, the light intensity detection device is used to detect the ultraviolet light source used to cure liquid crystal glass.

[0033] The light intensity detection device comprises: a mounting portion 10 and a sensor 20. The mounting portion 10 is used to be connected and fixed to a load; the sensor 20 is movably arranged on the mounting portion 10, and the sensor 20 has a measuring position and a stowed position. The measuring position is located in the working space so that the sensor 20 measures the light intensity in the working space, and the stowed position is located outside the working space so that the sensor 20 avoids the working space. The sensor 20 switches between the measuring position and the stowed position by moving.

[0034] The illuminance detection device of the present invention can move the sensor 20 to the measuring position when it is necessary to detect the illuminance, so as to detect the illuminance in the working space. After the illuminance detection is completed, the sensor 20 can be moved to the stowed position to avoid the working space and affect the normal work in the working space.

[0035] The light intensity detection device of the utility model is fixed on the carrier through the installation part 10, and is movably arranged on the installation part 10 with the sensor 20. The light intensity can be measured by moving the sensor 20 into the working space. After the measurement is completed, the light intensity can be moved away from the working space. Compared with the tooling in the prior art, there is no need to move the entire tooling, which is not only more convenient to use, but also can prevent the light intensity detection device from bumping against the workbench during the movement, thereby preventing the light intensity detection device or the workbench from being damaged.

[0036] The function of the support is to support the light intensity detection device by connecting with the mounting portion 10. The support may be a workbench, a bracket, a support plate or other structures. In this embodiment, the support is a workbench of an ultraviolet curing device. The structure of the light intensity detection device is further described below by taking the workbench as an example:

[0037] The light intensity detection device further includes: a shielding portion 30, the shielding portion 30 is movably connected to the mounting portion 10, and the shielding portion 30 has an avoidance position and a shielding position, the avoidance position is used to avoid the moving sensor 20, and the shielding position is used to shield the light source to prevent the light source from irradiating the sensor 20 in the stowed position, and the shielding portion 30 moves between the avoidance position and the shielding position. The light intensity detection device of the utility model is provided with the shielding portion 30, and when the sensor 20 is in the stowed position, the shielding portion 30 can shield the sensor 20 to prevent it from being irradiated by the light source or being contaminated, thereby protecting the sensor 20 and ensuring the measurement accuracy of the sensor 20.

[0038] In this embodiment, the mounting portion 10 includes: a connecting plate 11 and a connecting bolt 12, one end of the connecting bolt 12 is connected to the connecting plate 11, and the other end is connected to the workbench, the connecting plate 11 is connected and fixed to the bottom of the workbench through the connecting bolt 12, the connecting plate 11 has a first side and a second side, the first side of the connecting plate 11 faces the workbench, the second side of the connecting plate 11 faces away from the workbench, and there is a spacing space between the first side of the connecting plate 11 and the workbench for accommodating the shielding portion 30. A limiting column 121 is sleeved on the connecting bolt 12, the limiting column 121 is located on the first side of the connecting plate 11, and the limiting column 121 is used to limit the distance between the connecting plate 11 and the workbench, so that a spacing space is formed between the connecting plate 11 and the workbench, so that the shielding portion 30 can move in the spacing space.

[0039] The sensor 20 moves along the first direction (X direction) perpendicular to the connecting plate 11. That is, in this embodiment, the sensor 20 moves along the first direction (X direction) perpendicular to the connecting plate 11. Figure 3 The measuring position is located at a first side of the connecting plate 11 , and the stowed position is located at a second side of the connecting plate 11 .

[0040] The workbench is provided with a through hole, through which the sensor 20 rises to the top of the workbench to detect the illumination, and through which the sensor 20 descends to the bottom of the workbench to avoid the products on the workbench so that the workbench can be used normally.

[0041] The connecting plate 11 is provided with an avoidance hole 111 extending from the first end to the second end, and the avoidance hole 111 corresponds to the position of the through hole. When the sensor 20 is lifted or lowered, it passes through the avoidance hole 111 and the through hole, thereby realizing reciprocating movement between the measuring position and the stowed position.

[0042] Specifically, the sensor 20 moves to the top of the workbench and enters the working space by ascending and passing through the avoidance hole 111 and the through hole in sequence when in the stowed position, thereby realizing the detection of the ultraviolet light illumination. After the detection is completed, the sensor 20 moves to the bottom of the workbench by descending and passing through the through hole and the avoidance hole 111 in sequence, thereby avoiding the working space. At this time, since the connecting plate 11 and the sensor 20 are both under the workbench, the illumination detection device does not occupy the working space of the workbench. Therefore, after the first installation, the illumination detection device does not need to be removed after use, which can greatly save the time of manual operation and save manpower and material resources.

[0043] Moreover, since the movement direction of the sensor 20 is in the vertical direction, it will only occupy the space in the vertical direction during the movement, and will not occupy the additional space in the horizontal direction, so the occupancy rate of the horizontal space under the workbench can be saved. At the same time, since the sensor 20 is located above the workbench when measuring the position, it avoids being blocked by the workbench, so that the illuminance of the ultraviolet lamp above can be measured more accurately, thereby improving the accuracy of the measurement result.

[0044] In this embodiment, the shielding part 30 is a shielding plate, which is located in the spacing space and rotatably connected to the connecting plate 11. The rotation axis of the shielding part 30 is perpendicular to the connecting plate 11, that is, the rotation axis of the shielding part 30 is arranged in the vertical direction. When the sensor 20 is in the retracted position, the shielding part 30 rotates to the first side of the connecting plate 11 and covers the avoidance hole 111; when the sensor 20 moves, the shielding part 30 staggers the position of the avoidance hole 111 by rotating. By arranging the shielding part 30 in a rotating manner, the occupation of the horizontal space can be reduced and the space occupation rate can be improved.

[0045] In this embodiment, the light intensity detection device further includes: a light shielding plate 80, which is connected to the sensor 20, and the shape of the light shielding plate 80 matches the contour of the avoidance hole 111, and is used to shield the gap between the sensor 20 and the avoidance hole 111. In this way, the light of the ultraviolet lamp is prevented from irradiating other components through the gap between the sensor 20 and the avoidance hole 111, thereby protecting other components.

[0046] It is understandable that the light intensity detection device further includes: a first driving member 40 and a second driving member 50. The first driving member 40 is drivingly connected to the sensor 20 to drive the sensor 20 to move between the measuring position and the stowed position. The second driving member 50 is drivingly connected to the shielding portion 30 to drive the shielding portion 30 to move between the avoidance position and the shielding position. By providing the first driving member 40 and the second driving member 50, the sensor 20 and the shielding portion 30 can be driven to move by the first driving member 40 and the second driving member 50, respectively, so that there is no need to manually take and place the light intensity detection device, thereby improving work efficiency.

[0047] In some embodiments, in order to avoid collision between the sensor 20 and the shielding portion 30 , the first driving member 40 cooperates with the second driving member 50 so that the first driving member 40 drives the shielding portion 30 to move through the second driving member 50 during the process of driving the sensor 20 to move.

[0048] It should be noted that the linkage between the first driving member 40 and the second driving member 50 can be achieved by circuit control. For example, if the linkage is achieved by circuit control, a control device can be added, the first driving member 40 uses a motor, and the second driving member 50 uses a cylinder. The control device is respectively connected to the motor and the cylinder in communication, so that the motor rotation and the cylinder movement are respectively controlled by the control device, so as to achieve the linkage between the two. However, this is not restrictive. In other embodiments, the linkage between the first driving member 40 and the second driving member 50 can also be achieved by mechanical connection.

[0049] like Figure 3 In the illustrated embodiment, the light intensity detection device further includes: a linkage member 60. The linkage member 60 is fixedly connected to the first driving member 40, and the linkage member 60 is driven and matched with the second driving member 50, and the first driving member 40 realizes linkage and matching with the second driving member 50 through the linkage member 60. By setting the linkage member 60, the first driving member 40 realizes linkage and matching with the second driving member 50 through the linkage member 60. Compared with the circuit control method, the linkage and matching is more reliable, and the first driving member 40 and the second driving member 50 will not fail to match due to software or circuit failure, which effectively avoids the collision between the shielding part 30 and the sensor 20, and improves the reliability of the light intensity detection device.

[0050] Specifically, the linkage member 60 is drivingly connected to the first driving member 40, and the first driving member 40 is used to drive the sensor 20 and the linkage member 60 to move relative to the mounting portion 10 along the first direction, and a first guide portion 61 is provided on the linkage member 60; the second driving member 50 is rotatably arranged on the mounting portion 10, and the rotation axis of the second driving member 50 is parallel to the first direction, and a second guide portion 51 cooperating with the first guide portion 61 is provided on the second driving member 50; driven by the first driving member 40, when the linkage member 60 moves along the first direction, the first guide portion 61 of the linkage member 60 is driven to cooperate with the second guide portion 51 of the second driving member 50, so that the second driving member 50 can realize circumferential rotation. By providing the first guide portion 61 and the second guide portion 51, the linkage member 60 can realize circumferential rotation through the mutual cooperation of the first guide portion 61 and the second guide portion 51 during the movement relative to the second driving member 50, so that the shielding portion 30 can rotate to the avoidance position while the sensor 20 rises, or the shielding portion 30 can move to the shielding position while the sensor 20 descends, thereby realizing mechanical linkage.

[0051] In some optional embodiments, such as Figure 5 As shown, the second driving member 50 is a driving shaft, which is rotatably connected to the connecting plate 11, and the linkage member 60 is a cylindrical and hollow sleeve, which can only move in the first direction (axial direction of the driving shaft) relative to the connecting plate 11 and cannot rotate, and the linkage member 60 is sleeved on the driving shaft; the first guide portion 61 is a guide groove provided on the sleeve, which extends in the axial direction and circumferential direction of the sleeve, and the second guide portion 51 is a guide column provided on the outer wall of the driving shaft, which is located in the guide groove and can move along the guide groove. In this embodiment, the driving shaft is fixed relative to the connecting plate 11 in the axial direction and can rotate relative to the connecting plate 11 in the circumferential direction, while the sleeve can move relative to the connecting plate 11 in the axial direction of the driving shaft, but cannot rotate. By setting the guide groove and the guide column, since the guide groove extends along the axial and circumferential directions of the sleeve, when the sleeve moves relative to the drive shaft, the two will not only move relative to each other in the axial direction, but also rotate relative to each other in the circumferential direction. Since the drive shaft itself can rotate, the drive shaft will rotate circumferentially under the interaction of the guide groove and the guide column, thereby realizing the rotation of the shielding part 30.

[0052] like Figure 5As shown, the guide groove (first guide portion 61) extends along the axial direction of the sleeve (linkage member 60), and the guide groove has a straight section 611 and a rotating section 612 along the axial direction of the sleeve. The rotating section 612 extends in the axial direction and also extends in the circumferential direction. In the process of the sleeve driving the guide groove to move, when the guide column (second guide portion 51) is located in the straight section 611, the moving direction of the guide column is parallel to the groove wall, and both move in the X direction. When the guide column is located in the rotating section 612, since the groove wall of the rotating section 612 extends circumferentially and intersects with the moving direction of the guide column, the guide column contacts the groove wall of the rotating section 612, and the groove wall drives the drive shaft to rotate circumferentially through the guide column, thereby causing the shielding portion 30 to rotate synchronously.

[0053] like Figure 4 As shown, in this embodiment, a slide cylinder is fixedly connected to the connecting plate 11, the first driving member 40 is a driving slider on the slide cylinder, the driving rod of the slide cylinder is drivingly connected to the driving slider to drive the driving slider to reciprocate, one end of the mounting plate 70 is fixedly connected to the linkage member 60, and the other end is fixedly connected to the driving slider, so that the linkage member 60 is fixedly connected to the driving slider through the mounting plate 70, thereby realizing synchronous movement with the sensor 20.

[0054] It should be noted that the function of the mounting plate 70 is to connect the first driving member 40 and the linkage member 60 so that the first driving member 40 and the linkage member 60 move synchronously. Although in the present embodiment, the mounting plate 70 is used to connect the two, this is not restrictive. In some other embodiments not shown in the figure, a rigid structure such as a bracket or a block structure can be used to replace the mounting plate 70. In other words, as long as the structure can drive the first driving member 40 and the linkage member 60 to move synchronously, it is within the protection scope of the present utility model without violating the inventive concept and principle.

[0055] It should also be noted that the first guide portion 61 and the second guide portion 51 can both be one or more. When multiple first guide portions 61 and multiple second guide portions 51 are used, multiple action positions can be formed in the circumferential direction to make the rotation smoother.

[0056] Taking the example of two first guide portions 61 and two second guide portions 51, the process of the shielding portion 30 moving between the avoidance position and the shielding position is further described below:

[0057] The drive shaft (second drive member 50) is provided with two guide posts (second guide portion 51), which are spaced apart along the circumference of the drive shaft, and the two guide posts are located on both sides of the drive shaft, and the two guide posts and the drive shaft form a "cross" structure in the axial direction. There are also two guide grooves (first guide portion 61) on the sleeve (linkage member 60), which are arranged one by one with the guide posts. With this arrangement, the circumferential action position can be made more uniform, making the rotation process more stable.

[0058] like Figure 6 and Figure 7 As shown, the two guide grooves (first guide portion 61) relatively arranged on the sleeve (linkage 60) are symmetrically arranged with respect to the axis center of the sleeve, that is, the straight sections 611 of the two guide grooves are parallel to each other, and the angle, length and direction of the rotating section 612 extending in the circumferential direction are the same, thereby achieving the effect of making the two guide columns (second guide portion 51) rotate synchronously.

[0059] It should also be noted that by providing two groups of guide posts (second guide portions 51) and guide grooves (first guide portions 61) in coordination with each other, compared to one group of guide posts and guide grooves, the weight and rotational torque borne by each guide groove are reduced to 1 / 2 of that of one group, thereby further reducing the wear between the guide posts and the guide grooves, thereby extending the service life and maintaining the guiding accuracy.

[0060] When there is no need to detect the light intensity, the sensor 20 is located below the workbench, that is, in the retracted position, and the shielding portion 30 is located between the sensor 20 and the workbench, that is, in the shielding position, to prevent the light source from irradiating the sensor 20. At this time, the guide column (the second guide portion 51) is located at the top of the rotating section 612 of the guide groove (the first guide portion 61).

[0061] When it is necessary to measure the illumination, the driving slider (first driving member 40) of the slide cylinder rises along the X direction, raising the sensor 20 above the workbench to the measuring position, thereby detecting the illumination.

[0062] In the process of driving the slider (first driving member 40) to drive the sensor 20 to rise, it also drives the sleeve (linkage member 60) to move upward through the mounting plate 70, so that the sleeve (linkage member 60) rises relative to the drive shaft (second driving member 50) along the X direction, which is equivalent to the guide column (second guide portion 51) relatively descending in the rotating section 612 and interacting with the groove wall in the rotating section 612 in the circumferential direction, so that the drive shaft (second driving member 50) rotates, thereby driving the shielding portion 30 to rotate to the avoidance position, so that the sensor 20 approaches the shielding portion 30 in the X direction. At the same time, the guide column (second guide portion 51) drives the drive shaft (second driving member 50) to drive the shielding portion 30 to completely rotate to the avoidance position under the guidance of the rotating section 612, so that the shielding portion 30 avoids the sensor 20 to avoid interference.

[0063] When the height of the sensor 20 in the X direction exceeds the shielding part 30 until the measuring position, the guide column (second guide part 51) is already in the straight section 611 of the guide groove (first guide part 61). At this time, the sleeve (linkage 60) will not interact with the guide column (second guide part 51) in the circumferential direction while moving along the X direction. Therefore, the drive shaft (second drive member 50) will not rotate, and the shielding part 30 will always be in the avoidance position. At the same time, the light shielding plate 80 blocks the gap between the sensor 20 and the workbench to prevent the ultraviolet light emitted by the ultraviolet light source from passing through the gap between the sensor 20 and the workbench and irradiating the non-metallic material under the work platform to damage it.

[0064] When the detection is completed, the driving slider (first driving member 40) of the slide cylinder descends along the X direction, and the sensor 20 is lowered to the top of the workbench and enters the stowed position, so that the sensor 20 avoids the working space of the workbench.

[0065] When the sensor 20 descends in the X direction to a position close to the shielding part 30, at this time, the guide column (second guide part 51) is still in the straight section 611 of the guide groove (first guide part 61), so the shielding part 30 will still be in the avoidance position. When the sensor 20 approaches the position of the shielding part 30 in the X direction, the guide column (second guide part 51) is about to enter the rotating section 612 from the straight section 611. When the sensor 20 descends in the X direction to the bottom of the shielding part 30, the guide column (second guide part 51) enters the rotating section 612. As the driving slider (first driving member 40) of the slide cylinder continues to descend along the X direction, the sensor 20 gradually approaches the stowed position. At the same time, the guide column (second guide part 51) cooperates with the rotating section 612 to rotate the shielding part 30 from the avoidance position to the shielding position. After the sensor 20 descends to the stowed position, the shielding part 30 also rotates to the shielding position.

[0066] like Figure 8As shown, in order to prevent the sensor 20 from hitting the shielding part 30 during the rising process, the height D1 of the rotating section 612 of the sleeve (linkage 60) in the X direction is set to be smaller than the gap distance D2 between the lower surface of the shielding part 30 and the upper surface of the sensor 20, and the rotation angle of the rotating section 612 of the sleeve (linkage 60) can be set to 90°. The ratio of the rotation angle to the distance of the rotating section 612 of the sleeve (linkage 60) will affect the rotation smoothness of the shielding part 30 and the service life of the workpiece. When the ratio becomes smaller, the rotation smoothness of the shielding part 30 and the service life of the workpiece will increase, but the height D1 of the rotating section 612 in the X direction is limited by the distance D2 from the shielding part 30 to the sensor 20. Therefore, within the limited distance range, the height D1 of the rotating section 612 of the sleeve (linkage 60) in the X direction should be maximized.

[0067] It can be seen that during the lifting and lowering process of the sensor 20, the sleeve (linkage 60) will not rotate, but only move in the X direction. When the sleeve (linkage 60) moves up and down, the groove wall of the guide groove (first guide part 61) will give a lateral force to the guide column (second guide part 51), so that the guide column (second guide part 51) can move along the rotating section 612. This is because the groove wall of the rotating section 612 is inclined (that is, extending in the circumferential direction), and the groove wall gives the guide column (second guide part 51) an oblique force. For example, if the inclination angle of the groove wall is 45°, it will give the guide column (second guide part 51) a 45° force, but at the same time, the space for the guide column (second guide part 51) to move in the X direction is limited, so it can only move in the circumferential direction, that is, it can only rotate.

[0068] In this embodiment, an ultraviolet curing device is disclosed, comprising: an ultraviolet lamp, a workbench and the above-mentioned light intensity detection device. The ultraviolet lamp is used to irradiate the object to be cured; the workbench is located below the ultraviolet lamp, and the workbench has a workspace for placing the object to be cured. The workbench is provided with a through hole, and the sensor 20 of the light intensity detection device rises through the through hole to enter the workspace or descends through the through hole to the bottom of the workbench; the light intensity detection device is arranged below the workbench and corresponds to the through hole, the measuring position is in the workspace, and the stowed position is located below the workspace, and the sensor 20 rises and falls through the through hole to move between the measuring position and the stowed position.

[0069] When the ultraviolet curing equipment of the present invention is needed, the sensor 20 of the light intensity detection device can be raised to the top of the through hole to measure the overall original illumination value of the ultraviolet lamp. When not in use, the sensor 20 can be lowered to the bottom of the through hole to avoid affecting the normal use of the workbench.

[0070] There are multiple ultraviolet lamps and illumination detection devices, and all illumination detection devices are set in one-to-one correspondence with all ultraviolet lamps. By setting multiple illumination detection devices and setting them in one-to-one correspondence with ultraviolet lamps, the accuracy of measurement can be improved.

[0071] It can be understood that, in this embodiment, the ultraviolet curing device further includes: a control device and a storage unit. The control device is connected to the light intensity detection device for controlling the lifting of the sensor 20; the storage unit is connected to the sensor 20 for recording the light intensity data measured by the sensor 20. By setting the control device, the lifting of the sensor 20 can be conveniently controlled; by setting the storage unit, the measured data can be directly stored in the storage unit, eliminating the process of manual reading and then inputting the storage, thereby improving the detection efficiency.

[0072] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
