Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a glass sheet cutting thickness detection device. Background Technology

[0002] Raw glass sheets are a fundamental material in many industries such as construction, automotive, and electronics, and their thickness uniformity is a key indicator of product quality. Before cutting raw glass sheets, their thickness usually needs to be accurately measured to ensure the stability of the cutting process and the yield rate.

[0003] To achieve automated testing, existing technologies typically employ automated testing devices. These devices generally include a clamping mechanism for securing the glass sheet and a moving mechanism for carrying the testing probe. The clamping mechanism is responsible for stably fixing the large glass sheet in the testing position, which is fundamental to ensuring the accuracy of the testing data.

[0004] However, existing clamping mechanisms generally suffer from structural design deficiencies when clamping large, fragile glass sheets. To clamp the glass, multiple independent drive sources (such as cylinders) are often used on both sides. This method not only requires a complex synchronous control system to ensure the consistency of the jaw movements on both sides, but also, in actual operation, even slight drive delays or force differences can cause displacement or uneven stress on the glass sheet during clamping, thus affecting the accuracy of the inspection.

[0005] Furthermore, this non-linkage clamping method typically lacks automatic centering, requiring operators to perform tedious manual pre-alignment before clamping, significantly reducing production efficiency. If the alignment is inaccurate, the clamped glass will deviate from its theoretical center, leading to reference errors in subsequent automated testing procedures. In severe cases, stress concentration can even cause glass breakage, resulting in economic losses.

[0006] Therefore, this utility model proposes a glass sheet cutting thickness detection device to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a glass sheet cutting thickness detection device, which aims to improve the problems of complex clamping mechanism structure, difficulty in achieving automatic centering and uneven clamping force in the existing glass sheet cutting thickness detection device. This utility model aims to provide a glass sheet cutting thickness detection device with an improved structure that can effectively solve the above problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a glass sheet cutting thickness detection device, comprising: a base and a motor lead screw structure disposed above the base; and a clamping assembly disposed on the top of the base.

[0009] The clamping assembly includes a connecting seat fixed to the base, and a hydraulic cylinder fixed to the connecting seat; a connecting frame connected to the output end of the hydraulic cylinder; a connecting plate fixed to the inner wall of the connecting frame; a rotating seat fixed to the base, and a rotating plate rotatably connected to the rotating seat at the bottom; a linkage rod rotatably connected to the rotating plate and the connecting plate at both ends respectively; and a clamping block fixed to the top of the connecting plate.

[0010] The hydraulic cylinder, the connecting frame, the connecting plate, the linkage rod, and the rotating plate work together to form a transmission mechanism that converts the linear motion of the hydraulic cylinder into the synchronous centering motion of the clamping block.

[0011] Preferably, the clamping assembly further includes a slide rail fixed to the top of the base, and the bottom of the connecting plate is slidably connected to the slide rail.

[0012] Preferably, the rotating seat, rotating plate, linkage rod and connecting plate constitute a first linkage mechanism, and the clamping assembly further includes a second linkage mechanism symmetrically arranged with respect to the first linkage mechanism about the central axis of the hydraulic cylinder.

[0013] Preferably, the device further includes a movable block, which is threadedly connected to the motor lead screw structure.

[0014] Preferably, the sidewall of the movable block is fixed with a fixing component.

[0015] Preferably, the fixing component includes a hollow block fixed to the movable block and a pull rod slidably disposed on the inner wall of the hollow block, one end of the pull rod being connected to an arc-shaped clamping plate.

[0016] Preferably, the fixing component further includes a spring, which is sleeved on the outer wall of the pull rod.

[0017] Preferably, the two ends of the spring abut against the inner wall of the hollow block and the flange formed on the pull rod, respectively.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of complex structure, difficulty in automatic centering and unstable clamping of glass clamping devices in the prior art by setting a symmetrical linkage clamping assembly driven by a single power source, and using the linkage mechanism to convert linear motion into synchronous centering motion of clamping blocks on both sides.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 This utility model provides a glass sheet cutting thickness detection device, which aims to solve the problems of difficulty in automatic centering, uneven clamping force and complex structure when clamping glass sheets in the prior art.

[0024] like Figure 1As shown, the glass sheet cutting thickness detection device includes a base 2 and a motor screw structure 1 fixed on the base 2. The base 2 provides a mounting base for the entire device, and the motor screw structure 1 is used to construct a vertical motion mechanism. The device also includes a clamping assembly 3 fixed on the top of the base 2. The clamping assembly 3 includes a connecting seat 304 fixed on the base 2 and a hydraulic cylinder 305 fixedly mounted through the connecting seat 304. The output end of the hydraulic cylinder 305 is connected to a connecting frame 306. Two connecting plates 307 are symmetrically fixed on the inner wall of the connecting frame 306. When the hydraulic cylinder 305 works, the output end of the hydraulic cylinder 305 pushes the connecting frame 306, thereby causing the two connecting plates 307 to produce synchronous linear motion. To ensure the smoothness of the movement of the connecting plates 307, the clamping assembly 3 also includes a slide rail 303 fixed on the top of the base 2. The bottom of the connecting plate 307 is slidably connected to the slide rail 303.

[0025] Furthermore, the clamping assembly 3 also includes a rotating seat 301 fixed to the base 2. The bottom of the rotating plate 302 is rotatably connected to the rotating seat 301 to form a rotating pair. One end of the linkage rod 308 is rotatably connected to the rotating plate 302, and the other end of the linkage rod 308 is rotatably connected to the connecting plate 307. The linear motion of the connecting plate 307 is associated with the rotational motion of the rotating plate 302 through the linkage rod 308, thereby forming a transmission path that converts the linear motion into a precise clamping action. Finally, the clamping block 309 used to clamp the glass sheet is fixed to the top of the connecting plate 307.

[0026] The fixing component 4 includes a hollow block 401 fixed to the side wall of the movable block 5, and a pull rod 402 slidably disposed on the inner wall of the hollow block 401. One end of the pull rod 402 is connected to an arc-shaped clamping plate 404 for clamping the detector. In the assembled state, the pull rod 402 can slide back and forth in the internal space of the hollow block 401. The fixing component 4 also includes a spring 403, which is sleeved on the outer wall of the pull rod 402. The two ends of the spring 403 abut against the inner wall of the hollow block 401 and the flange formed on the pull rod 402, respectively. This structure allows the action of pushing the detector in to force the arc-shaped clamping plate 404 to move the pull rod 402 and compress the spring 403 when the detector is installed. After installation, the elastic potential energy stored in the spring 403 will continuously apply a rebound force to the pull rod 402, thereby forming a stable clamping force on the detector through the arc-shaped clamping plate 404.

[0027] As a preferred embodiment, in order to further improve the stability and guiding accuracy of the linear motion of the connecting plate 307, a slide rail 303 is also fixed on the top of the base 2, and the bottom of the connecting plate 307 is slidably connected to the slide rail 303. The slide rail 303 accurately guides and limits the movement trajectory of the connecting plate 307 to prevent deviation or vibration when subjected to force. As another preferred embodiment, in order to achieve automatic centering and clamping of the glass sheet and ensure uniform distribution of clamping force, the rotating seat 301, rotating plate 302, linkage rod 308 and connecting plate 307 constitute a first linkage mechanism. The clamping assembly 3 also includes a second linkage mechanism that is symmetrically arranged with the first linkage mechanism about the central axis of the hydraulic cylinder 305. The two linkage mechanisms are driven by the same hydraulic cylinder 305, thereby ensuring that the clamping blocks 309 on both sides can move towards or away from each other in absolute synchronization. As a further preferred embodiment, in order to support the testing instrument and achieve precise automated testing motion, the device also includes a moving block 5, which is threadedly connected to the motor lead screw structure 1, and a fixing component 4 is fixed on the side wall of the moving block 5. In the specific construction of the fixing component 4, in order to achieve quick loading and unloading and reliable fixing of the testing instrument, please refer to... Figure 4 and Figure 5 The fixing component 4 includes a hollow block 401 fixed to the movable block 5, and a pull rod 402 that can slide on the inner wall of the hollow block 401. One end of the pull rod 402 is connected to an arc-shaped clamping plate 404. The fixing component 4 also includes a spring 403 sleeved on the outer wall of the pull rod 402. The two ends of the spring 403 abut against the inner wall of the hollow block 401 and the flange formed on the pull rod 402, respectively. This configuration utilizes the preload of the spring 403 to provide a continuous and stable clamping effect.

[0028] Working principle: When it is necessary to fix the glass sheet, the hydraulic cylinder 305 is activated. The output end of the hydraulic cylinder 305 pushes the connecting frame 306, which in turn drives the two connecting plates 307 fixed on the inner wall of the connecting frame 306 to move synchronously. During the movement, the bottom of the connecting plate 307 slides along the slide rail 303 fixed to the base 2, ensuring the linearity and stability of the movement. The linear movement of the connecting plate 307 drives the rotating plate 302 to rotate around the rotating seat 301 through the rotating linkage 308. Through this set of symmetrically arranged linkage mechanisms, the single linear movement output by the hydraulic cylinder 305 is accurately converted into the synchronous and opposite centering clamping movement of the clamping blocks 309 on both sides, thereby stably and evenly clamping the glass sheet. When thickness detection is required, the detector is first pushed into the arc-shaped clamping plate 404 of the fixing component 4. This pushing action will cause the pull rod 402 to slide in the hollow block 401 and compress the spring 403 sleeved on the outer wall of the pull rod 402. After installation, the continuous rebound force generated by the compressed spring 403 will firmly clamp the detector through the pull rod 402 and the arc-shaped clamping plate 404. Then, the motor screw structure 1 is started. The motor screw structure 1 drives the moving block 5 to move up and down precisely in the vertical direction through the thread transmission, thereby driving the entire fixing component 4 and the detector fixed on the moving block 5 to complete the scanning detection of the thickness of the glass sheet.
