Description

Technical Field

[0001] This utility model belongs to the field of sampling inspection technology for transparent sheets such as glass and acrylic, and specifically relates to a sampling inspection cart that can be raised and lowered for adjustment. Background Technology

[0002] For larger glass substrates, they are typically stored in A-frame racks before random inspection. Since the glass substrates are placed at an angle within the A-frame racks, they need to be transferred to the inspection table for testing. The inspection table is quite far from the A-frame racks, and given the large size of the glass substrates, manual transfer poses a significant risk of collision with other objects, damaging the glass substrates and affecting their quality. Furthermore, with the inspection height and area of ​​the inspection table already fixed, moving the glass substrates to the corresponding inspection platform introduces new risks of damage. Therefore, it is necessary to design a new sampling inspection device to address the problems of limited performance, limited inspection area, difficulty in adjusting the inspection area, unstable inspection quality, and high rates of missed or false detections in existing sampling inspection equipment. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a height-adjustable sampling trolley that allows for both adjustment of the testing platform height and the testing platform area.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] This utility model provides a height-adjustable sampling trolley, including a lower frame, an upper frame, a lifting mechanism disposed between the lower frame and the upper frame to drive the upper frame to rise and fall, a lifting control mechanism for controlling the lifting mechanism, and a testing platform disposed on the upper frame. The testing platform includes a sample stage that can extend and retract along its plane and testing instruments disposed on the sample stage.

[0006] In one embodiment, the lifting mechanism includes a hydraulic cylinder, a first sliding structure, a second sliding structure, and a cross-link structure. The first sliding structure and the second sliding structure are respectively disposed on the lower frame and the upper frame. The cross-link structure includes a first link and a second link that are cross-hinged. The two ends of the first link are respectively hinged to the sliding part of the first sliding structure and the upper frame. The two ends of the second link are respectively hinged to the sliding part of the second sliding structure and the lower frame. The output end of the hydraulic cylinder is fixedly connected to the sliding part of the first sliding structure.

[0007] In one embodiment, the first sliding structure includes a first slide rail, a first slider that slides in conjunction with the first slide rail, a first fixed plate, and a push block. The first slider and the push block are respectively connected to the first fixed plate. The output end of the hydraulic cylinder is connected to the push block. One end of the first connecting rod is hinged to the first fixed plate.

[0008] The second sliding structure includes a second slide rail, a second slider that slides in conjunction with the second slide rail, and a second fixed plate connected to the second slider. One end of the second connecting rod is hinged to the second fixed plate.

[0009] In one embodiment, the cross-link structure further includes a third link and a fourth link that are cross-hinged and parallel to the first link and the second link. The first link and the second link, and the third link and the fourth link are hinged to the same hinge rod. The two ends of the third link are respectively hinged to the sliding part of the first sliding structure and the upper frame, and the two ends of the fourth link are respectively hinged to the sliding part of the second sliding structure and the lower frame.

[0010] In one embodiment, the lifting control mechanism is a hydraulic manual control mechanism, which includes a hydraulic oil tank, a gear pump connected to the hydraulic oil tank, and a handwheel for controlling the gear pump. The gear pump is connected to the hydraulic cylinder.

[0011] In one embodiment, the sample stage is assembled from a retractable aluminum profile, and the surface of the sample stage is distributed with a plurality of vertically upward support columns.

[0012] In one embodiment, the top of the support column is made of polyurethane.

[0013] In one embodiment, the testing instrument is a plurality of cameras that are slidably disposed along the edge of the testing platform.

[0014] In one embodiment, the lower frame is provided with vertically upward elastic buffer supports at its end corners.

[0015] In one embodiment, the upper frame is provided with handles on its sides.

[0016] Compared with existing technologies, the adjustable sampling trolley of this invention can adjust both the detection height and the detection area of ​​the detection platform. It can be applied to the sampling of glass products on multiple different production lines simultaneously. Simply push the sampling trolley to the corresponding production line. Whether the glass is manually transported to the detection platform of the sampling trolley or extracted by a robotic arm, it can be adjusted to a suitable detection platform height, effectively reducing the risk of damaging the glass substrate during sampling. It also eliminates the problem of the robotic arm being unable to reach the glass. The adjustable detection area allows it to adapt to the detection of glass substrates of different sizes. In addition, when the glass sampling needs to be carried out by different equipment, the sampling trolley is very convenient for transporting samples and can adapt to the detection height of different equipment, further reducing the risk of damaging the glass substrate. The structure is simple and reasonable, easy to manufacture and install, and low in cost. Attached Figure Description

Detailed Implementation

[0022] See also Figure 1-4This embodiment provides a height-adjustable sampling inspection cart for sampling inspection of glass and acrylic sheets. It includes a lower frame 1, an upper frame 2, a lifting mechanism 3 located between the lower frame 1 and the upper frame 2 to drive the upper frame 2 to rise and fall, a lifting control mechanism 4 to control the lifting mechanism 3, and a detection platform 5 located on the upper frame 2. The detection platform 5 includes a sample stage 51 that can extend and retract along its plane and a testing instrument 53 located on the sample stage 51.

[0023] In this embodiment, the lifting mechanism 3 includes a hydraulic cylinder 31, a first sliding structure, a second sliding structure, and a cross-link structure. The first sliding structure and the second sliding structure are respectively disposed on the lower frame 1 and the upper frame 2. The cross-link structure includes a first link 321 and a second link 322 that are cross-hinged, and also includes a third link 323 and a fourth link 324 that are cross-hinged and parallel to the first link 321 and the second link 322. The first link 321 and the second link 322, and the third link 323 and the fourth link 324 are hinged to the same hinge rod 325. The two ends of the first link 321 are respectively hinged to the push block 334 of the first sliding structure and the upper frame 2. The two ends of the second link 322 are respectively hinged to the sliding part of the second sliding structure and the lower frame 1. The output end of the hydraulic cylinder 31 is fixedly connected to the sliding part of the first sliding structure. The two ends of the third link 323 are hinged to the sliding part of the first sliding structure and the upper frame 2, respectively. The two ends of the fourth link 324 are hinged to the sliding part of the second sliding structure and the lower frame 1, respectively. Specifically, the ends of the first link 321, second link 322, third link 323, and fourth link 324 are hinged via bearings. Compared to directly using a pneumatic lever for lifting, the cross-link lifting mechanism of the lifting mechanism 3 can achieve a wider lifting stroke. When the cross-link structure only includes the cross-hinged first link 321 and second link 322, a single double-row bearing consisting of an angular contact bearing and a thrust bearing is sufficient to stably hinge the ends of the links.

[0024] In this embodiment, the first sliding structure includes a first slide rail 331, a first slider 332 that slides in conjunction with the first slide rail 331, a first fixing plate 333, a push block 334, and a limiting block 335. The first slider 332 and the push block 334 are respectively connected to the first fixing plate 333. The output end of the hydraulic cylinder 31 is connected to the push block 334. One end of the first connecting rod 321 is hinged to the first fixing plate 333. The second sliding structure includes a second slide rail 341, a second slider 342 that slides in conjunction with the second slide rail 341, and a second fixing plate 343 connected to the second slider 342. One end of the second connecting rod 322 is hinged to the second fixing plate 343.

[0025] In this embodiment, the lifting control mechanism 4 is a hydraulic manual control mechanism, which includes a hydraulic oil tank 41, a gear pump 42 connected to the hydraulic oil tank 41, a handwheel 43 controlling the gear pump 42, and a hydraulic control valve pilot mechanism. The oil outlet of the gear pump 42 is connected to the hydraulic cylinder 31 through an oil circuit. Figure 1 As shown, the hydraulic control valve pilot mechanism includes a directional valve adjusting handle 44, a manual directional valve 45, a pressure reducing valve 46, a pilot-operated relief valve 47, and a shut-off valve 48 arranged sequentially. The gear pump 42 is connected to the hydraulic cylinder 31. The hydraulic control valve pilot mechanism allows control of the hydraulic oil flow between the gear pump 42 and the hydraulic cylinder 31 simply by operating the directional valve adjusting handle 44. Regardless of whether the hydraulic cylinder 31 drives the upper frame 2 to rise or fall, the rotation direction of the handwheel 43 remains the same, eliminating the need to change its direction and simplifying operation. The hydraulic manual control mechanism avoids complex wiring and uses the hydraulic cylinder 31 for drive, resulting in smooth power output and preventing slippage.

[0026] In this embodiment, the hydraulic cylinder 31 and the first sliding structure are mounted on the first mounting plate 71, the lifting control mechanism 4 is mounted on the second mounting plate 72, the second sliding structure is mounted on the third mounting plate 73, and the first connecting rod 321 and the third connecting rod 323 are hinged on the fourth mounting plate 74. The sample stage 51 is assembled from retractable aluminum profiles, and multiple vertically upward support columns 55 are distributed on the surface of the sample stage 51 to support the glass and acrylic sheets. The top of the support columns 55 is made of polyurethane. Medical-grade polyurethane does not generate dust and will not contaminate transparent products such as glass and acrylic sheets. At the same time, it will not generate dust that affects the accuracy of the testing instrument 53. The testing instrument 53 consists of several cameras that slide along the edge of the testing platform 5. One camera can be installed on each of the four sides of the sample stage 51 to detect edge cracks, thickness, and burrs on the product. By mounting the camera bracket on the camera slide rail 59, the image acquisition range of the camera on the sample stage 51 can be adjusted. Each of the four corners of the lower frame 1 is equipped with vertically upward elastic buffer supports 57 to cushion the descent of the upper frame 2. For example, when maintenance is required on the lifting mechanism 3, the upper frame 2 will no longer be supported by the connecting rod but will naturally fall onto the four elastic buffer supports 57 of the lower frame 1. The top of the elastic buffer supports 57 is made of polyurethane. The sides of the upper frame 2 are equipped with handles 6 for easy pulling of the trolley.

[0027] The sampling trolley in this embodiment includes a lifting mechanism 3 that drives the upper frame 2 to rise and fall, and a sample platform 51 that can extend and retract along the plane. When performing sampling operations, after the sampling trolley is pushed to the sampling area, the area of ​​the sample platform 51 is first adjusted according to the size of the glass to be sampled. Then, the lifting mechanism 3 raises and lowers the sample platform 51 to a height suitable for a robotic arm of a person or other testing instrument to place the glass. After the glass to be sampled is placed on the sample platform 51, the edge of the product is measured by testing instruments such as a camera mounted on the side to analyze whether the product is qualified.

[0028] The adjustable sampling trolley of this embodiment can adjust both the detection height and the detection area of ​​the detection platform, allowing for simultaneous sampling of glass products on multiple production lines. Simply push the sampling trolley to the corresponding production line. Whether glass is manually moved to the sampling trolley's detection platform or extracted by a robotic arm, a suitable detection platform height can be adjusted, effectively reducing the risk of damaging the glass substrate during sampling and eliminating situations where the robotic arm cannot reach the glass. The adjustable detection area allows for the inspection of glass substrates of different sizes. Furthermore, when glass sampling requires different equipment, the sampling trolley is convenient for transporting samples and adapts to the height of different equipment, further reducing the risk of damaging the glass substrate. The structure is simple and reasonable, easy to manufacture and install, and inexpensive.
