Description

Technical Field

[0001] This application relates to the field of lighting technology, specifically to a glass lampshade balance detection system and detection method. Background Technology

[0002] With the development of modern interior decoration and lighting design, blown glass lampshades have become the first choice for many designers and consumers due to their unique and varied artistic beauty and excellent light transmission. However, due to the limitations of the blown molding process, the produced glass lampshades often have uneven wall thickness. This unevenness not only affects the visual effect of the lampshade, but more importantly, it causes an uneven distribution of weight inside the lampshade. When such a lampshade is installed on a light fixture, the uneven weight distribution may cause the lampshade to tilt to varying degrees, seriously affecting the overall aesthetics and safety of the light fixture.

[0003] In view of the above issues, it is necessary to perform a balance test on the glass lampshade after its fabrication to ensure that the lampshade maintains a good balance after installation. Therefore, there is a need for a simple and quick testing method for glass lampshades. Summary of the Invention

[0004] This application proposes a glass lampshade balance testing system and method, which can quickly and easily test the balance of the finished lampshade, ensuring that the lampshade can maintain a good balance after installation, effectively improving the overall aesthetics and safety of the lamp.

[0005] To achieve the above objectives, the present application adopts the following technical solution:

[0006] In a first aspect, this application provides a glass lampshade balance detection system, including a projection panel capable of displaying projections, a motor disposed at the upper front end of the projection panel, and a suspension rope;

[0007] A suspension device that is suspended from the motor by the suspension rope and rotated by the motor, the suspension device can securely suspend the glass lampshade;

[0008] It also includes a balance plate fastened to the upper end of the suspension device and a lighting source disposed at the front end of the suspension device, the lighting source causing the balance plate to project onto the projection plate.

[0009] This application projects the balance plate onto the projection plate using a light source located at the front of the projection plate. Operators can observe the changes in the projection to intuitively judge the tilt state of the glass lampshade, thereby quickly identifying and screening imbalance problems.

[0010] Furthermore, the system employs a motor-driven suspension device, which can precisely control the rotation angle of the glass lampshade, ensuring high accuracy in the testing process and improving the reliability of the test results. The suspension device and the glass lampshade are fixedly connected. When the glass lampshade tilts due to uneven weight distribution caused by uneven wall thickness, the suspension device tilts synchronously with the lampshade, ensuring that they always maintain a consistent angle and more accurately reflect the actual tilt of the lampshade. This system is simple in design, easy to operate, and suitable for glass lampshades of various shapes and sizes.

[0011] In some feasible implementations, the suspension rope is connected to the motor via a fixed post, and the fixed post is provided with a fastening pin to secure the suspension rope, facilitating adjustment of the height of the suspension device.

[0012] In some feasible implementations, a first profile is also included to fix the projection panel. The first profile guides the motor to be adjustable up and down. The simple structure enables the adjustment of the motor's height and also ensures the consistency of the positional relationship between the projection panel and the motor.

[0013] In some feasible implementations, a second profile is also included, which guides the lighting source in an adjustable manner, thereby achieving distance adjustment of the lighting source through a simple structure.

[0014] In some feasible implementations, a third profile that moves back and forth on the second profile is also included. The third profile guides the lighting source to be adjustable up and down, and the adjustment of the lighting source in the front-back and up-down directions is realized through the two end profiles.

[0015] In some feasible implementations, the system also includes a worktable for attaching and fixing the first profile and the second profile, and a level instrument set on the upper part of the worktable. By utilizing the high flatness of the profiles to make them fit the worktable, and then using the level instrument to ensure three-dimensional balance, the levelness of the entire system can be guaranteed with a simple structure.

[0016] In some feasible implementations, the suspension device includes a pushing device connected to the suspension rope, a fixed clamp that can move up and down and is fitted onto the pushing device, and a rotating clamp that rotates relative to the fixed clamp and is pushed by the pushing device and clamps the edge of the lampshade with the fixed clamp. The lampshade can be clamped by its own weight, which can achieve rapid detection.

[0017] In some feasible implementations, a controller for controlling the speed and start / stop of the motor is also included.

[0018] Secondly, this application also provides a method for testing the balance of a glass lampshade using the glass lampshade balance testing system described above, wherein at least one balance reference line is pre-marked on the projection plate, and the balance reference line is the horizontal projection line of the balance plate in the three-dimensional horizontal state of the level and in the unloaded state.

[0019] Furthermore, before testing, the level of the level is verified. After installing the lampshade, the lighting source is turned on, and the motor rotation is adjusted to simulate the rotation of the lampshade. The balance of the lampshade is judged based on the projection of the balance plate and the horizontal deviation of the balance reference line. Attached Figure Description

[0030] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0031] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0032] First, the characteristics of the glass lampshade to be tested by the glass lampshade balance testing system in this case will be explained. When blown glass is formed into a thin lampshade shape, its surface area is relatively large. Therefore, it is greatly affected by the process, such as raw material distribution, mold design, temperature control, and blowing pressure. This results in the weight of the lampshade being inconsistent in the 360° direction, leading to a deviation in balance.

[0033] Meanwhile, the glass lampshade is installed in a suspended state, meaning it is in a state of self-weight balance. In this case, uneven weight distribution can cause it to tilt after suspension. Therefore, during production and shipment, its balance needs to be checked and addressed, requiring a testing system that can simulate actual suspended conditions. Crucially, the testing system used in the production environment needs to be easy to debug and allow for lampshade replacement.

[0034] Please refer to Figure 1 This application provides a glass lampshade balance detection system, including a projection panel 100 capable of displaying projections. A motor 200 is disposed at the upper front end of the projection panel 100, and a suspension device 400 is disposed below the motor 200 and suspended by a suspension rope 300. The rotation of the motor 200 drives the suspension device 400 to rotate. Preferably, the motor 200 is a stepper motor, which can simulate rotation in various application states.

[0035] Referring to reference 7, the suspension device 400 securely suspends the glass lampshade 500. "Securely suspending" here means that when the glass lampshade 500 is unbalanced and tilts, the suspension device 400 also tilts synchronously, and the rotation of the suspension device 400 simultaneously drives the glass lampshade 500 to rotate. Please refer to the following for details. Figure 2 The suspension rope 300 is connected to the motor 200 via a fixing post 310. The fixing post 310 can be a hollow post into which the suspension rope 300 can be inserted, and the suspension rope 300 is secured by a fastening pin 311, facilitating adjustment of the height of the suspension device 400. One end of the fixing post 310 is connected to the shaft of the motor 200; this connection method is a common industry practice and will not be described in detail.

[0036] A balance plate 600, which can be a circular plate with uniform weight distribution, is fastened to the upper end of the suspension device 400. It also tilts synchronously with the tilt of the glass lampshade 500 and rotates synchronously with the rotation of the suspension device 400.

[0037] Please refer to the reference. Figure 1 , Figure 5 and Figure 6A light source 700 is provided at the front end of the suspension device 400, and the light source 700 shines on the projection panel 100. The suspension device 400, the glass lampshade 500, and the balance plate 600 are projected onto the projection panel 100. Preferably, the light source 700 is an adjustable brightness LED light, but other lighting methods can be selected according to actual needs.

[0038] At this time, the motor 200 rotates to simulate the actual installation state of the glass lampshade 500. The tilt of the glass lampshade 500 is magnified and projected onto the balance plate 600 on the projection plate 100. Operators can visually judge the tilt state of the glass lampshade by observing the changes in the projection of the balance plate 600, thereby quickly identifying and filtering imbalance problems.

[0039] In addition, the system uses a suspension device 400 driven by a motor 200, which can precisely control the rotation angle of the glass lampshade 500, ensuring the high accuracy of the detection process and improving the reliability of the detection results.

[0040] For ease of control, the balance detection system of this application is equipped with a controller 800, which may include a motor control knob 810 for controlling the speed and start / stop of the motor 200, a switch button 820 for turning the lighting source 700 on and off, and a brightness knob 830 for adjusting the brightness of the lighting source 700.

[0041] In practical applications, balance detection systems can be used in mass production, which requires rapid adjustment of the balance state and positional relationships. This application presents an innovative design that can achieve this using a simple structure.

[0042] First, please refer to Figure 1 and Figure 3 The projection panel 100 is vertically fixed using a first profile 910 located at its rear end. The fixing of the projection panel 100 and the first profile 910 can be achieved through ribs, a common industry practice for fixing panels and profiles, and will not be elaborated upon here. The profile used here can be an aluminum alloy profile, which offers the advantage of a very stable planar structure on its end face and four sides, facilitating installation. Utilizing this feature, the motor 200 can be fixed to its front end, spaced apart from the projection panel 100, via an extension profile 210. Specifically, the extension profile 210 can be connected to the first profile 910, allowing the motor 200 to be adjusted vertically under the guidance of the first profile 910. The motor 200 and the extension profile 210 are fixed using fixing washers 220. This ensures the consistency of the positional relationship between the projection panel 100 and the motor 200.

[0043] In addition to adjusting the height of motor 200, the height of lighting source 700 and its distance from projection panel 100 also need to be adjusted.

[0044] To address this, a second profile 920 is provided between the lighting source 700 and the projection panel 100, arranged along the front-to-back direction. The second profile 920 guides the lighting source 700 in an adjustable front-to-back direction, achieving distance adjustment of the lighting source 700 through a simple profile structure. Furthermore, the lighting source 700 is mounted on a third profile 930, which is arranged vertically and guided by the second profile 920 to move the lighting source 700 back and forth. The third profile 930 also guides the lighting source 700 to move vertically. In practical applications, the lighting source 700 can be fixed to a transition profile 710; it is the transition profile 710 that actually moves the lighting source 700 vertically.

[0045] After adjusting the positional relationship, it is also necessary to maintain a stable three-dimensional horizontal state. To this end, the balance detection system of this application includes a worktable 940 that fits and fixes the first profile 910 and the second profile 920. The worktable 940 has adjusting feet at least at its four corners. Leveling the worktable 940 using adjusting feet is a common technique and will not be described in detail here. A level 950 is installed at the upper end of the worktable 940. The level 950 can be adjusted in three dimensions, meaning its horizontality can be confirmed in all three dimensions. Thus, this system utilizes the flatness of the profiles to ensure their fit with the worktable 940, and then uses the level 950 to ensure three-dimensional balance, thereby guaranteeing the overall system's horizontality with a simple structure.

[0046] Once the three-dimensional balance is maintained as described above, the balance of the glass lampshade can be tested. Please refer to... Figure 5 and Figure 6 As a reference for testing, balance reference lines 110 can be pre-marked on the projection plate 100. The number and spacing of these lines can be determined according to the actual situation. In this embodiment, the balance reference lines 110, which are projected vertically from two balance plates 600, are used for testing. Here, the balance reference lines 110 are horizontal to the projection lines of the balance plates 600 in the unloaded state. When the weight of the glass lampshade 500 deviates, it will tilt, which will cause the balance plates 600 to tilt as well. At this time, the degree of weight deviation of the glass lampshade 500 can be determined by the deviation relationship between the projection of the balance plate 600 and the balance reference lines 110.

[0047] During operation, first verify the levelness of the level gauge 950, then install the lampshade 500 and turn on the lighting source 700 for testing. During testing, the rotation of the motor 200 is adjusted to simulate the rotation of the lampshade 500, allowing for 360° measurement of the weight deviation of the lampshade 500.

[0048] In addition to stability, the testing process also requires a design that allows for quick assembly and disassembly to improve testing efficiency. Please refer to [reference needed]. Figure 4 and Figure 7 The suspension device 400 includes a pushing device 410 connected to the suspension rope 300, and a fixed clamp 420 that can move up and down is fitted onto the pushing device 410. That is, the pushing device 410 is positioned by the pulling of the suspension rope 300, and the lampshade 500 is clamped by the weight of the fixed clamp 420.

[0049] For details, please refer to Figures 8 to 10 The fixing clamp 420 has a hollow column 421, and a guide sleeve 422 may be provided on its top. The corresponding pushing device 410 includes a conical pushing part 411 and a guide column 412, and a positioning step 413 is provided at the connection between the pushing part 411 and the guide column 412. The top of the guide column 412 is connected to the lifting rope 300. When the lifting rope 300 pulls the pushing device 410 and the fixing clamp 420 sinks, the bottom of the hollow column 421 and the positioning step 413 will contact each other, so as to achieve accurate positioning and clamping.

[0050] Corresponding to the fixed clamp 420, the suspension device 400 also includes a rotating clamp 430 that rotates relative to the fixed clamp 420 and is pushed by the pushing device 410. The rotating clamp 430 rotates relative to the fixed clamp 420 via a rotating shaft 431 and, together with the fixed clamp 420, clamps the edge 510 of the lampshade 500 from both the top and bottom. When the fixed clamp 420 is lifted in an unloaded state, the rotating clamp 430 is in a converged state towards the central axis of the hollow column 421, meaning it can be directly inserted into the lampshade 500. When the fixed clamp 420 is lowered after being inserted into the lampshade 500, the rotating clamp 430 unfolds outward due to the action of the pushing device 410, while the fixed clamp 420 is lowered by its own weight, thus clamping the edge 510 of the lampshade 500. In this way, the lampshade 500 can be quickly switched using the simple suspension device 400, enabling rapid detection.

[0051] To ensure more stable clamping, a claw portion 432 is provided at the bottom of the rotating clamp 430 facing the lamp cover 500, and an extension portion 423 is provided on the outside of the fixed clamp 420, corresponding to the claw portion 432 and clamping the edge 510 of the lamp cover 500.

[0052] As stated above, this case protects a glass lampshade balance testing system and testing method, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
