Technical Field

[0001] This application relates to the field of measuring equipment technology, and in particular to a measuring device. Background Technology

[0002] With the rapid development of automated production and intelligent inspection technologies, industrial production is increasingly demanding higher precision and efficiency in online material measurement, sorting, and quality control. Typical scenarios include the dimensional inspection of electronic components. In these scenarios, materials are typically transported to the measurement station via conveyor belts and inspected by sensors, cameras, or probes.

[0003] However, in existing technologies, materials are prone to lateral movement, rotation, or tilting during the conveying process, making it difficult to move along the preset position. This deviation will directly affect the gripping, transfer, and measurement of materials, leading to measurement errors, missed detections, or misjudgments, thus reducing yield and stability. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a measuring device that can push materials to a preset position to prevent deviation.

[0005] To achieve the above objectives, this application adopts the following technical solution: A measuring device includes a feeding component and a straightening component.

The straightening component includes a linear drive and an abutment. The linear drive is disposed beside the feeding component. The drive end of the linear drive is connected to the abutment. The linear drive is used to drive the abutment to move along the second direction to abut against and push the material.

[0006] In one embodiment, the measuring device includes a first transfer component and a measuring component.

The second transfer component is used to transport the material from the measuring component to the receiving end, and the discharge end is used to convey the material to the discharge position.

[0010] In one embodiment, the measuring device includes a defective product collection component located beside the discharge component and close to the receiving end. The defective product collection component is used to grab materials at the receiving end that are determined to be unqualified by the measuring component.

[0011] In one embodiment, the discharge station includes a defective station, and the defective product collection component includes a fixing frame, a gripper, and a conveyor. The fixing frame is located next to the discharge component, and the gripper is slidably connected to the fixing frame. The gripper is used to grip the material that is determined to be defective by measurement at the receiving end and place it on the conveyor. The conveyor is used to transport the material to the defective station.

[0012] In one embodiment, the defective product collection component further includes a stamping component, which is slidably connected to the fixing frame for stamping the material on the conveyor.

[0013] In one embodiment, the stamping component includes a slide, a lifting drive, and a stamping part.

[0017] In this application, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0018] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “radial,” and “circumferential” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] See Figure 1 and Figure 2 This application provides a measuring device, including a feeding component 1 and a correcting component. The feeding component 1 is used to transport materials along a first direction. The feeding component 1 is provided with a correcting component on at least one side. The correcting component can be selectively moved along a second direction to push the material to a preset position. The first direction and the second direction are arranged at an angle.

[0021] To describe clearly, Figure 1 In the diagram, X represents the first direction and Y represents the second direction.

[0022] In practical applications, the feeding component 1 transports materials along a first direction, and the correction component is disposed on at least one side of the feeding component 1. It can selectively move along a second direction at an angle to the first direction and push the material to a preset position.

[0023] Specifically, the feeding component 1 can be a conveyor belt. The material is placed on the conveyor belt, which transports the material along a first direction. When the material may experience lateral displacement due to inertia or vibration, a correction component located on the side of the conveyor belt can move along a second direction. Since the second direction forms an angle with the conveying direction, the pushing action of the correction component generates a component force perpendicular to the conveying direction, pushing the displaced material back along the predetermined path, so that the material is located in a preset position. When the material reaches the preset position, the correction component stops moving or returns to its original position to avoid interfering with the subsequent material conveying.

[0024] Compared to existing technologies, this embodiment forms a correction mechanism through movable correction components, which can adapt to the offset changes of materials of different sizes. The lateral offset of the material during the conveying process is corrected in real time, ensuring that the material entering the measurement station is in the precise coordinate position, effectively eliminating the positioning error caused by rotation or tilt, and establishing stable reference conditions for subsequent precision measurement.

[0025] See again Figure 2 The correction component includes a linear drive 21 and an abutment 22. The linear drive 21 is disposed on the side of the feeding component 1. The driving end of the linear drive 21 is connected to the abutment 22. The linear drive 21 is used to drive the abutment 22 to move along the second direction to abut against the material and push the material.

[0026] In practical applications, when material is conveyed along the first direction on the feeding component 1, the linear drive 21 drives the abutment 22 to move along the second direction. During movement, the abutment 22 contacts the side of the material, continuously applying lateral thrust to gradually move the material towards a preset position. After the material reaches the preset position, the linear drive 21 resets the abutment 22, preventing interference with the normal conveying of subsequent materials. This combination of the linear drive 21 and the abutment 22 simplifies the mechanical layout while ensuring correction accuracy.

[0027] Among them, the linear drive component 21 refers to the power device that can generate linear motion, which can be implemented by an electric push rod or a cylinder.

[0028] See again Figure 1 and Figure 3 The measuring device also includes a first transfer component 3 and a measuring component 4. The measuring component 4 is disposed downstream of the correcting component along a first direction. The first transfer component 3 is used to transport the material from the feeding component 1 to the measuring component 4.

[0029] In practical applications, the first transfer component 3 serves as a material transfer mechanism, which can be implemented using a robotic arm, suction cup, or pneumatic gripper to achieve directional transportation of materials from the correction station to the measurement station, thus preventing the materials from shifting position during the transfer process.

[0030] Furthermore, the measuring component 4 is positioned downstream of the correcting component along the first direction. After the material completes position correction at the feeding component 1, the first transfer component 3 performs a gripping action, directly transferring the material along the first direction to the detection area of ​​the measuring component 4. Since both the measuring component 4 and the correcting component are located in the first direction, they can be linearly connected, and the material does not need to undergo turning or path switching, always moving along the first direction during the transfer process. For example, when the first transfer component 3 uses a vacuum suction cup, the material maintains the same position as after correction when it is adsorbed and transferred. This arrangement can maintain the continuity of the material's posture and eliminate secondary positional deviations caused by changes in direction.

[0031] The first transfer component 3 can adopt a suction cup structure. The suction cup is slidably connected to the external guide rail and is driven by a drive motor to move or lift between various workstations to realize the transfer of materials.

[0032] See again Figure 1The measuring component 4 may include a thickness measuring mechanism 41, which includes a mounting frame 411, a measuring instrument 412, and a sliding bracket 413. The measuring instrument 412 is connected to the mounting frame 411, and the sliding bracket 413 is slidably connected to the mounting frame 411 to selectively slide out from the mounting frame 411 and receive materials.

[0033] In practical applications, the mounting frame 411 serves as the basic support structure and the main frame structure of the measuring instrument 412. The sliding bracket 413 forms a sliding fit with the mounting frame 411 via a guide rail or slide rail. When the material arrives at the measuring station, the sliding bracket 413 slides outward from the inside of the mounting frame 411 along the guide rail or slide rail, forming an extended bearing plane. The material is placed on the surface of the sliding bracket 413 extending out of the mounting frame 411, and then the sliding bracket 413 retracts into the mounting frame 411 along the guide rail or slide rail, facilitating the measuring instrument 412 to detect the thickness of the material. After the detection is completed, the sliding bracket 413 slides out of the mounting frame 411 again, facilitating the removal of the material and freeing up space for subsequent material flow.

[0034] In this embodiment, the sliding bracket 413 and the mounting bracket 411 work together to achieve dynamic extension and contraction of the bearing surface, which not only ensures the accurate positioning of materials of different sizes, but also avoids interference with the subsequent conveying mechanism through the retraction action of the sliding bracket 413, thus saving device space.

[0035] The aforementioned thickness measuring mechanism 41 is mainly used to measure the thickness of materials. In practical applications, it is also necessary to detect other parameters of the material. (See [reference needed]). Figure 3 The measuring component 4 also includes a barcode scanning mechanism 43 and a CCD detection mechanism 42. The barcode scanning mechanism 43 and the CCD detection mechanism 42 are arranged downstream of the correction component along the first direction. The barcode scanning mechanism 43, the CCD detection mechanism 42 and the thickness measuring mechanism 41 are arranged in sequence along the first direction to facilitate the sequential detection of different parameters of the material.

[0036] It should be noted that the barcode scanning mechanism 43 is mainly used for material identification and traceability, reading barcodes / QR codes (Cell ID, batch, workstation information) and binding the measurement results to individual materials; the CCD inspection mechanism 42 is a vision inspection system used for non-contact inspection and positioning of materials for size, position, appearance, characters / barcodes, etc.

[0037] See Figure 4 The thickness measuring mechanism 41 includes an elastic element 414, which is vertically connected between the mounting frame 411 and the measuring instrument 412. The elastic element 414 is used to balance the weight of the measuring instrument 412. The measuring instrument 412 can be a torque meter.

[0038] It should be noted that when measuring the thickness of a material, the torque meter usually needs to be pressed against the surface of the material before the displacement difference is read.

[0039] In practical applications, when the measuring instrument 412 presses down on the material, its own weight will affect the measurement data. Therefore, this application provides an elastic element 414. The elastic element 414 connects the mounting bracket 411 and the measuring instrument 412 in the vertical direction. When the measuring instrument 412 moves downwards towards the material, the elastic element 414 generates a reverse force through stretching or compression deformation to counteract the influence of gravity on the measuring instrument 412 and ensure the repeatability and accuracy of the thickness measurement results.

[0040] See again Figure 1 The measuring device includes a discharge component 5 and a second transfer component 7. The discharge component 5 includes a receiving end and a discharge end. The second transfer component 7 is used to transport the material from the measuring component 4 to the receiving end, and the discharge end is used to transport the material to the discharge position.

[0041] In practical applications, after the material is detected by the measuring component 4, it is picked up by the second transfer component 7 and transferred to the receiving end of the discharge component 5. The discharge end can then convey the material along a specific conveying path to the corresponding discharge position according to the sorting instructions corresponding to the measurement results. This achieves automated sorting after material measurement, replacing manual operation with mechanical transfer and improving sorting efficiency. For example, when the measurement determines the material to be qualified, the discharge end conveys the material to the qualified product station; if it is determined to be unqualified, a path switching mechanism guides the material to the unqualified product station. The discharge component 5 can employ a conveyor belt or similar structure.

[0042] It is understood that the second transfer component 7 and the first transfer component 3 can adopt a similar structure, which will not be elaborated here.

[0043] See again Figure 1 The measuring device includes a defective product collection component 6, which is located next to the discharge component 5 and close to the receiving end. The defective product collection component 6 is used to grab materials that are determined to be unqualified by the measuring component 4 at the receiving end.

[0044] In practical applications, the defective product collection component 6 refers to the component used for automatic sorting of defective products. Specifically, it can use a robotic arm, pneumatic gripper or vacuum suction cup to perform the gripping action. The separation of defective products is achieved through the coordinated action of the gripping action and the discharge component 5.

[0045] Specifically, after the measuring component 4 completes the inspection, all materials are conveyed to the receiving end. At this time, the defective product collection component 6 grabs the unqualified materials by clamping or adsorption, while the qualified materials are transported to the discharge end via the discharge component 5. See again Figure 1The discharge station includes the defective station. The defective product collection component 6 includes a fixed frame 61, a gripper 62, and a conveyor 63. The fixed frame 61 is located next to the discharge component 5. The gripper 62 is slidably connected to the fixed frame 61. The gripper 62 is used to grip the material that is determined to be defective by measurement at the receiving end and place it on the conveyor 63. The conveyor 63 is used to transport the material to the defective station.

[0046] In practical applications, when the material is determined to be unqualified in the measuring component 4, the gripper 62 moves along the fixed frame 61 through the sliding connection structure to the top of the receiving end, performs the gripping action, carries the material back to the starting position of the conveyor 63, and places the material on the conveyor 63. The conveyor 63 transports the material to the unqualified station. The independent conveying channel constructed by the conveyor 63 enables the spatial separation of unqualified products from qualified products on the main conveyor line, reducing the difficulty of sorting.

[0047] See Figure 5 The defective product collection component 6 also includes a stamping component 64, which is slidably connected to the fixing frame 61 for stamping the materials on the conveyor 63.

[0048] In practical applications, when the conveyor 63 delivers materials that have been determined to be non-conforming to the stamping area, the stamping device 64 is used to stamp the non-conforming materials to ensure that the non-conforming materials are marked, improve the accuracy of non-conforming material identification, and prevent material confusion.

[0049] See again Figure 5 The stamping component 64 includes a slide 641, a lifting drive 642, and a stamping part 643. The slide 641 is slidably connected to the fixed frame 61 in the horizontal direction to drive the stamping part 643 to move horizontally. The lifting drive 642 is connected to the slide 641, and the stamping part 643 is slidably connected to the lifting drive 642 in the vertical direction. The lifting drive 642 is used to drive the stamping part 643 to rise and fall to achieve stamping of materials.

[0050] In practical applications, the slide 641 and the fixed frame 61 form a horizontally sliding moving platform. The lateral position of the stamping part 643 on the material surface is adjusted by this horizontal sliding. The lifting drive unit 642 serves as the power unit for driving the vertical movement of the stamping part 643, controlling the contact pressure between the stamp and the material through the lifting motion. The stamping part 643 refers to the functional module that performs the marking action, and the depth of the stamp head's downward pressure is controlled by the stroke of the lifting drive unit 642.

[0051] When the material is picked up and placed on the conveyor 63, the slide 641 slides horizontally to directly above the material, aligning the stamping part 643 with the preset marking area on the material. The lifting drive 642 then drives the stamping part 643 to descend vertically, causing the stamp head to contact the material surface to complete the marking action. Afterward, the stamping part 643 returns to its initial height. Through the coordinated action of the slide 641 and the lifting drive 642, the stamping part 643 can independently adjust its position in the horizontal and vertical directions, avoiding marking misalignment caused by differences in material size or positional shifts.

[0052] It should be noted that multiple stamping sections 643 can be configured, and all stamping sections 643 are connected to the slide 641. Each stamping section 643 is connected to a lifting drive section 642. Each lifting drive section 642 is used to drive different stamping sections 643 individually. The multiple stamping sections 643 can be divided into first-class defective products, second-class defective products, and third-class defective products. The multiple stamping sections 643 can classify and stamp different defective materials to facilitate subsequent sorting and management.

[0053] The slide block 641 can be implemented by combining a linear guide rail and a slider, the lifting drive unit 642 can be implemented by a cylinder or an electric push rod, and the stamping unit 643 can be implemented by a spring-return stamp head.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0056] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
