Description

Technical Field

[0001] The utility model relates to the technical field of crystal rod packaging detection, in particular to a tool for preventing size errors in finished product packaging square rods. Background Art

[0002] Our company's N-type crystal ingot G10 is a square bar with a rectangular cross-section. Its short side is 182±0.25mm and its long side is 183.75±0.25mm. After machining and grinding, it passes through the assembly line or re-grinding and enters the finished product packaging stage. Before packaging, the operator will use a suction cup to lift the square bar and turn the four sides of the square bar over to check for dirt, broken edges, line marks and other defects. After the inspection is completed, the square bar will be palletized.

[0003] Currently, customers require that the long and short sides of the square bars on the pallet be consistent. After the pallet is shipped, the bars will proceed directly to the next processing step (gluing and slicing). If the long and short sides are inconsistent, a large number of square bar slices will have different sizes, leading to customer complaints. However, during defect inspections on all four sides of the bars, some operators flip the bars (only once or three times) and fail to restore them to their original state, resulting in inconsistent long and short sides after the pallet is formed. These inconsistencies are difficult to detect visually, as the difference between the short and long sides is only about 1.5 mm. Furthermore, the gaps between the pallets are small, making it impossible to re-measure using existing inspection tools such as vernier calipers and tape measures. Utility Model Content

[0004] The purpose of the utility model is to develop a tool for preventing errors in the size of finished product packaging square bars, which can quickly detect the long side and short side of the crystal bar so that operators can identify the long side and short side of the crystal bar.

[0028] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] 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 the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] like Figures 1-3 As shown, the utility model discloses a tool for preventing errors in the size of finished product packaging square bars, including a base 1, a fixed claw 2 is provided on the base 1, a movable claw 3 is also rotatably provided on the base 1, a driving component is provided in the base 1 for driving the movable claw 3 to always rotate in a direction close to the fixed claw 2, and a limit component is also provided in the base 1 for limiting the rotation range of the movable claw 3.

[0033] The movable jaw 3 and the fixed jaw 2 clamp the crystal ingot to inspect both its long and short sides. When inspecting the short side of the ingot, the movable jaw 3 is at its maximum rotational position, close to the fixed jaw 2. When inspecting the long side of the ingot, the movable jaw 3 is at its maximum rotational position, away from the fixed jaw 2.

[0034] The base 1 has a rectangular frame structure, one of its long sides being a detection reference edge 11, which contacts the crystal ingot. The fixed jaw 2 is connected to the outer wall of one end of the detection reference edge 11, and the movable jaw 3 is pivotally connected to the outer side of the other end of the detection reference edge 11. The sidewalls of the fixed jaw 2 and movable jaw 3 that approach each other are flat, and the sidewall of the fixed jaw 2 is perpendicular to the detection reference edge 11. When the movable jaw 3 rotates to its extreme position near the fixed jaw 2, the sidewall of the movable jaw 3 is perpendicular to the detection reference edge 11.

[0035] A support 5 is provided on the short side of the base 1 on the side of the movable claw 3, and the movable claw 3 is rotatably connected to the support 5. An inner claw 4 is provided on the inner side of the base 1, and one end of the inner claw 4 is connected to the movable claw 3 in the support 5, and the inner claw 4 and the movable claw 3 form an L shape.

[0036] The drive assembly is located between the bottom of the inner jaw 4 and the bottom of the base 1. It includes a first slot on the bottom of the inner jaw 4, a second slot 7 on the long side of the base 1 below the first slot 6, and a spring (not shown) connected between the first and second slots 6 and 7. The spring pulls the first slot 6 toward the second slot 7, causing the inner jaw 4 to swing away from the detection reference edge 11. The inner jaw 4 then drives the movable jaw 3 to swing toward the fixed jaw 2 to its maximum rotational position.

[0037] In addition, the driving component can also be arranged between the top of the inner claw 4 and the detection reference edge 11 of the base 1. Accordingly, the first slot 6 is arranged at the top of the inner claw 4, and the second slot 7 is arranged on the inner wall of the detection reference edge 11 above the first slot 6. The spring is arranged between the first slot 6 and the second slot 7. The elastic force of the spring pushes the first slot 6 away from the second slot 7, thereby realizing the inner claw 4 swinging toward the side away from the detection reference edge 11.

[0038] The position-limiting assembly includes an upper protrusion 9 and a lower protrusion 8 disposed on the base 1, above and below the end of the inner jaw 4 away from the movable jaw 3. The bottom end of the upper protrusion 9 corresponds to the maximum rotational position of the movable jaw 3 away from the fixed jaw 2. When the inner jaw 4 contacts the upper protrusion 9, the movable jaw 3 is at its maximum rotational position away from the fixed jaw 2. The top end of the lower protrusion 8 corresponds to the maximum rotational position of the movable jaw 3 toward the fixed jaw 2. When the inner jaw 4 contacts the lower protrusion 8, the movable jaw 3 is at its maximum rotational position toward the fixed jaw 2.

[0039] When inspecting the crystal rod, the operator holds the base 1 and inserts the fixed claws 2 and the movable claws 3 from the two side walls of the crystal rod until the inspection reference edge 11 of the base 1 contacts the crystal rod. At this time, check the condition of the inner claw 4. If the inner claw 4 contacts the upper protrusion 9, it is the long side of the crystal rod. If the inner claw 4 contacts the lower protrusion 8, it is the short side of the crystal rod.

[0040] The utility model has the advantages of simple structure, low cost, easy manufacture and storage, convenient operation and use, and can separate the long side and short side of the crystal ingot by directly inserting the tooling into the crystal ingot, thus avoiding misplacement.

[0041] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
