[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the clamping mechanism of the easily adjustable optical glass clamp provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the lower surface structure of the clamping mechanism of the easily adjustable optical glass clamp shown. Figure 3 for Figure 1 The diagram shows the overall structure of the easily adjustable optical glass clamp. The easily adjustable optical glass clamp includes: a device disk 1 and multiple clamping mechanisms 4;
[0021] Multiple clamping mechanisms 4 are movably disposed on the upper surface of the device disk 1 along multiple radial directions;
[0022] Multiple clamping mechanisms 4 have the same structure. One of the clamping mechanisms 4 includes an arched connecting seat 41. An extension piece 42 is laterally arranged in the middle of the front end surface of the connecting seat 41. Two guide pieces 43 are arranged on the front end surface of the extension piece 42, which are symmetrical to each other and extend to both sides. The upper surface of the two guide pieces 43 is vertically opened with a sliding groove 44 arranged along its length. The inside of the two sliding grooves 44 is slidably connected to the sliders 45 along their length. The bottom end of the two sliders 45 is laterally rotatably connected to a clamping wheel 46. An electrically controlled telescopic rod 47 is laterally fixedly connected to the upper surface of the extension piece 42. A movable block 48 is fixedly connected to the front end of the electrically controlled telescopic rod 47. A vertical shaft 49 is vertically fixedly connected to the top end of the movable block 48. A hinge strip 410 is hinged between the vertical shaft 49 and the two sliders 45.
[0023] A fixing block 411 is laterally fixed to the front end of the lower surface of the extension piece 42. A crossbar 412 is laterally fixed to the rear end surface of the fixing block 411. A slide block is slidably connected to the outer surface of the crossbar 412 along its length. An adjusting wheel 414 is laterally rotatably connected to the bottom end of the slide block. A clamping belt 415 is provided on the outer surface of the adjusting wheel 414 and the two clamping wheels 46. A spring 413 is fixedly connected between the slide block and the fixing block 411.
[0024] When the piston rod of the electrically controlled telescopic rod 47 in the clamping mechanism 4 extends, the movable block 48 at its front end will move synchronously. During this process, since the vertical shaft 49 set at the top of the movable block 48 is hinged to the two sliders 45 through the hinge bar 410, the two sliders 45 will move outward under the drive of the other end of the hinge bar 410, thereby synchronously driving the two clamping wheels 46 to move outward. Conversely, they will move inward, and the length of the clamping belt 415 between the two clamping wheels 46 will change accordingly. When clamping small-diameter glass sheets, the distance between the two clamping wheels 46 can be reduced, and vice versa. This device can clamp glass sheets of different sizes.
[0025] By using this device to clamp the glass sheet, stability can be ensured during the glass coating process.
[0026] The adjusting wheel 414 is affected by the spring 413 and is always subjected to a backward thrust, thereby pulling the clamping belt 415 closer.
[0027] The connecting seat 41, the extension plate 42 and the two guide plates 43 are made of stainless steel and are integrally formed.
[0028] Stainless steel has high structural strength and is not easily deformed, making it suitable for this type of structure.
[0029] The upper surface of the device disk 1 is provided with multiple mounting grooves 2 along multiple radial directions. Electric slide rails 3 are fixedly connected to the interior of the multiple mounting grooves 2 along their length directions. Multiple clamping mechanisms 4 are respectively arranged on the upper surface of the sliding part of the multiple electric slide rails 3.
[0030] Multiple mounting slots 2 are evenly spaced along the circumference of the device disk 1.
[0031] When using this device to clamp a glass sheet, the glass sheet is moved above the device disk 1 of the device, and then multiple electric slide rails 3 are activated. The sliding part of the electric slide rails 3 drives multiple clamping mechanisms 4 to move toward the glass sheet until the multiple clamping mechanisms have completed clamping the glass sheet.
[0032] Both sides of the bottom end of the connecting seat 41 extend outward to form connecting side plates. The upper surfaces of the two connecting side plates are vertically connected with connecting holes. The clamping mechanism 4 is installed on the upper surface of the sliding part of the electric slide rail 3 through the connecting side plates and connecting holes.
[0033] The clamping mechanism 4 is connected to the sliding part of the electric slide rail 3 via the connecting seat 41 and screws, making it easy to replace when a clamping mechanism 4 is damaged or unusable.
[0034] The working principle of the easily adjustable optical glass clamp provided by this utility model is as follows:
[0035] When the piston rod of the electrically controlled telescopic rod 47 in the clamping mechanism 4 extends, the movable block 48 at its front end will move synchronously. During this process, since the vertical shaft 49 set at the top of the movable block 48 is hinged to the two sliders 45 through the hinge bar 410, the two sliders 45 will move outward under the drive of the other end of the hinge bar 410, thereby synchronously driving the two clamping wheels 46 to move outward. Conversely, they will move inward, and the length of the clamping belt 415 between the two clamping wheels 46 will change accordingly. When clamping small-diameter glass sheets, the distance between the two clamping wheels 46 can be reduced, and vice versa. This device can clamp glass sheets of different sizes. By clamping the glass sheets with this device, the stability can be ensured during the glass coating operation.
[0036] Compared with related technologies, the easily adjustable optical glass clamp provided by this utility model has the following advantages:
[0037] Beneficial effects:
[0038] This invention provides an easily adjustable optical glass clamp. By setting up a clamping mechanism, the device has two clamping wheels that can slide to the sides respectively. The distance between the two clamping wheels is adjusted by a movable block. When clamping small-diameter glass, the distance between the two clamping wheels is reduced, and vice versa. This allows the device to clamp glass sheets of various specifications, ensuring that the glass sheets can be stably coated, thus improving the practicality of the device.
[0039] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
