[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In this utility model, terms such as "upper," "lower," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe the utility model and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0040] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0041] Furthermore, the terms "disposed," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0042] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0043] With economic development and rising living standards, people's expectations for leather are also increasing. Natural leather, primarily genuine leather, is highly sought after by consumers for its strength, stain resistance, wear resistance, breathability, and pleasant feel. However, genuine leather often exhibits surface defects such as scars and holes. Therefore, to meet consumers' demanding aesthetics and effectively control leather wear, a more meticulous manual defect inspection process has been introduced before production. However, this manual inspection method not only significantly increases workers' workload but also reduces efficiency. For example, a common inspection method currently involves inspectors laying the leather to be inspected on a workbench, pressing it with their waist, and then stretching it with their hands. Alternatively, they can secure the leather with a tool and then manually stretch it, inspecting the stretched area for defects. This method is not only time-consuming and labor-intensive, but can also cause defects to expand due to excessive stretching force, or fail to fully expand due to insufficient stretching force, thus compromising inspection accuracy and efficiency.

[0044] Based on this, the leather inspection device disclosed in the present application places the leather to be inspected on the outer peripheral surfaces of the first workbench and the second workbench, and moves the second workbench away from the first workbench in a first direction, so that the leather to be inspected is stretched along the first direction. At the same time, because the leather to be inspected is covered on the stretching rod, by driving the first driving member inside the first and second workbench, the first driving member drives the push rod portion through the driving portion to extend out of the first mounting hole to push the stretching rod to move along the second direction, so that the leather to be inspected is stretched along the second direction, and the first direction intersects the second direction. Since the leather to be inspected is stretched by the leather inspection device, it avoids the inspector from stretching it manually, which is conducive to reducing the inspector's workload and improving inspection efficiency. At the same time, the movement of the workbench and the stretching rod are used to stretch the leather to be inspected in the intersecting first direction and / or second direction, making the surface of the leather to be inspected smoother. This not only allows the inspector to observe the leather to be inspected more intuitively, but also improves the inspection accuracy and further improves the inspection efficiency.

[0045] The technical solution of the present utility model will be further described below in conjunction with the embodiments and drawings.

[0046] See also Figure 1-2 , Figure 1 This is a structural diagram of the leather inspection equipment provided in the embodiment of the present application. Figure 2 This is a structural diagram of the first workbench and the second workbench provided in the embodiment of the present application. The embodiment of the present application provides a leather inspection device 100, which includes a first workbench 1, a second workbench 2, two first driving members 3 and a stretching rod 32.

[0047] The second workbench 2 is spaced apart from the first workbench 1 along the first direction, and the second workbench 2 can move along the first direction relative to the first workbench 1. The outer peripheral surfaces of the first workbench 1 and the second workbench 2 are configured to place the leather to be tested. When the second workbench 2 moves away from the first workbench 1 along the first direction, the second workbench 2 drives the leather to be tested to stretch along the first direction.

[0048] Optionally, the first workbench 1 and the second workbench 2 may be arranged on a rotating shaft, and the first workbench 1 is fixed relative to the rotating shaft, while the second workbench 2 is movable relative to the rotating shaft along a first direction. The first direction may be an axial direction along the rotating shaft.

[0049] It is understandable that the movement of the second workbench 2 away from the first workbench 1 along the first direction can be achieved by electric means, of course, it can also be achieved by manual means. For example, when the manual method is adopted, the second workbench 2 can be directly pushed to move the second workbench 2 on the rotating shaft to move away from or closer to the first workbench 1. For another example, when the electric method is adopted, a third drive member can be added to drive the second workbench 2 to move along the first direction to move away from or closer to the first workbench 1. Exemplarily, the third drive member may include but is not limited to the design of a motor with a screw or a slider, or the third drive member may also be a cylinder or an electric cylinder.

[0050] Optionally, the outer circumferences of the first workbench 1 and the second workbench 2 are each provided with a first mounting hole 21. One of the two first driving members 3 is disposed within the first workbench 1, and the other first driving member 3 is disposed within the second workbench 2. In other words, a first driving member 3 is disposed within both the first workbench 1 and the second workbench 2. The first driving member 3 includes a first driving portion and a push rod portion 31. The push rod portion 31 is connected to the first driving portion and is disposed corresponding to the first mounting hole 21. The push rod portion 31 can extend out of the first mounting hole 21 under the drive of the first driving portion.

[0051] Optionally, the first driving member 3 can be a cylinder, and the first driving part is the cylinder body part of the cylinder, or the first driving member 3 can also be a hydraulic cylinder, and the first driving part is the cylinder body part of the hydraulic cylinder, or the first driving member 3 can also be other driving structures, but is not limited thereto.

[0052] Multiple stretching rods 32 are connected to the push rod part 31, and the multiple stretching rods 32 are respectively located on the outer circumference of the first workbench 1 and the second workbench 2. The stretching rods 32 are configured to move along the second direction under the drive of the push rod part 31 of the first driving member 3, so that the leather to be tested is stretched along the second direction; wherein the first direction intersects with the second direction.

[0053] Optionally, as can be seen from the above, a first mounting hole 21 is provided on the outer peripheral surface of the first workbench 1 and the second workbench 2, and the push rod portion 31 can be provided corresponding to the first mounting hole 21, so that the push rod portion 31 can extend out of the first mounting hole 21 under the drive of the first driving portion to push the tensioning rod 32 to move along the second direction, or, it can also retract into the first mounting hole 21 under the drive of the first driving portion.

[0054] It is understandable that if Figure 1 As shown, the first direction may be the length extension direction of the first workbench 1 and the second workbench 2, and the second direction may be a direction perpendicular to the first direction. For example, the second direction may be along the outer peripheral radial direction of the first workbench 1 and the second workbench 2.

[0055] For example, each of the first and second workbenches 1 and 2 is provided with a first mounting hole 21. Each of the first and second workbenches 1 and 2 is provided with a first drive member 3. Each first drive member 3 includes a push rod portion 31, and each push rod portion 31 is connected to a stretching rod 32, with the first and second directions being perpendicular to each other. During the leather inspection process, the leather to be inspected is placed on the outer circumference of the first and second workbenches 1 and 2. This allows the second workbenches 2 to move away from the first workbenches 1 in the first direction while the first drive member 3 drives the push rod portion 31 to push the stretching rod 32 on each workbenches in the second direction, thereby stretching the leather to be inspected in the first and second directions.

[0056] By driving the first workbench 1, the second workbench 2 and the stretching rod 32 to move through the driving member, the leather to be inspected wrapped on the outer surfaces of the first workbench 1 and the second workbench 2 can be evenly stretched along the first direction and the second direction. This not only avoids manual stretching of the leather, reduces the workload of inspectors, and improves inspection efficiency, but also allows the leather to be inspected to maintain a flat surface after stretching, allowing inspectors to observe the surface of the leather to be inspected more intuitively, thereby improving inspection accuracy and further improving inspection efficiency.

[0057] In some embodiments, in order to ensure that the leather to be inspected has a flat surface in every direction, the outer peripheral surfaces of the first workbench 1 and the second workbench 2 are provided with a plurality of first mounting holes 21 spaced apart; the first driving member 3 has a plurality of push rod portions 31, and each push rod portion 31 of the first driving member 3 is provided corresponding to each first mounting hole 21; each push rod portion 31 is provided with a stretching rod 32.

[0058] It is understandable that the number of the first mounting holes 21, push rod portions 31 and extension rods 32 can be set according to the desired number of planes. For example, the number of the first mounting holes 21, push rod portions 31 and extension rods 32 can be three, four or more.

[0059] Optionally, when the number of the first mounting holes 21 is at least three, the angles formed by any first mounting hole 21 and two adjacent first mounting holes 21 may be the same or partially the same, but is not limited thereto.

[0060] For example, the outer circumferences of the first and second workbenches 1 and 2 are each provided with four first mounting holes 21 at intervals. Each first driving member 3 has four push rods 31, one corresponding to each first mounting hole 21. Each push rod 31 is provided with a stretching rod 32. Furthermore, the second direction corresponding to each first mounting hole 21 is perpendicular to the second direction corresponding to the adjacent first mounting hole 21, and each second direction is perpendicular to the first direction. Because the four stretching rods 32 move along the second direction corresponding to each first mounting hole 21, the leather to be inspected wrapped around the outer circumferences of the first and second workbenches 1 and 2 is stretched into four planes, allowing inspectors to inspect defects on the four planes in sequence. By providing multiple first mounting holes 21, as well as corresponding push rods 31 and stretching rods 32, not only can the leather to be inspected be fully stretched, but it can also form multiple flat surfaces on the leather to be inspected, which helps avoid the problem of missing defects due to poor inspection angles by inspectors, further improving inspection accuracy.

[0061] In some embodiments, the first workbench 1 and the second workbench 2 may be prismatic workbench, the side surfaces and bottom surfaces of the first workbench 1 and the second workbench 2 are flat, and a plurality of first mounting holes 21 are respectively provided on the side edges of the first workbench 1 and the second workbench 2 .

[0062] like Figure 2 As shown, for further illustration, the first workbench 1 is a workbench where the stretching rod 32 does not move, while the second workbench 2 is a workbench where the stretching rod 32 moves in the second direction. Taking the second workbench 2 as an example, the second workbench 2 is a regular triangular prism-shaped workbench. The side surfaces of the second workbench 2 are rectangular planes, and a hole is provided on the first side edge 22 and the second side edge 23 of the side surface. The bottom surface of the second workbench 2 is a regular triangular plane. The first mounting hole 21 is located at the center of a side edge of the second workbench 2, formed by the combination of the first side edge 22 of any side surface and the hole on the second side edge 23 of the adjacent side surface. The stretching rod 32 is located on the side edge. The leather to be tested is placed on the side surfaces of the first workbench 1 and the second workbench 2. By using this prismatic workbench, the leather to be tested is not easily slipped or deformed when placed. The first mounting hole 21 and the stretching rod 32 are arranged on the side edge, which can maximize the integrity of the side of the workbench and improve the versatility of the workbench. At the same time, since the side of the workbench is flat, the leather to be tested is also flat after being arranged on the workbench, which makes it easier for the leather to be tested to be stretched by the stretching rod 32. In addition, the flat workbench design is simpler and less expensive, which can effectively reduce production costs.

[0063] In some embodiments, in order to enable the workbench to rotate to avoid the inspector having to bend over to check other planes of the leather to be inspected, the leather inspection equipment 100 further has a second driving member 4, which includes a second driving part 42 and a rotating part 41 connected to the second driving part 42. The first workbench 1 and the second workbench 2 are both arranged in the rotating part 41, and the second driving part 42 is configured to drive the rotating part 41 to rotate, thereby driving the first workbench 1 and the second workbench 2 to rotate.

[0064] Figure 3 This is a schematic diagram of the structure of the first workbench and the second workbench (partial structure omitted) provided in the embodiment of the present application. For further demonstration, the first workbench 1 shows the external structure of the workbench, and the second workbench 2 shows the internal structure of the workbench. Figure 3 As shown, the first workbench 1 and the second workbench 2 are regular triangular prism-shaped workbench, and a third mounting hole 45 is provided on the bottom surface of the first workbench 1 and the second workbench 2. The rotating portion 41 of the second driving member 4 (such as the aforementioned rotating shaft) is fixedly connected to the first workbench 1 and the second workbench 2 through the third mounting hole 45. Outside the first workbench 1 and the second workbench 2, one end of the rotating portion 41 is fixedly connected to the second driving portion 42, and the other end of the rotating portion 41 is connected to the bearing portion 43. Since the workbench is a regular triangular prism-shaped workbench, the leather to be inspected covering the outer circumference of the first workbench 1 and the second workbench 2 has three flat surfaces, namely, a first surface, a second surface, and a third surface. After the leather to be inspected is placed, the rotating portion 41 drives the first workbench 1 and the second workbench 2 to rotate together along the third direction under the drive of the second driving member 4. During the inspection process, the inspector first inspects the first side of the leather to be inspected. After confirming that there are no defects, the inspector activates the second drive unit 42, causing the rotating unit 41 to rotate the first and second worktables 1 and 2 in the third direction, thereby rotating the leather from the first side to the second side. Similarly, after inspecting the second side, the inspector rotates the leather from the second side to the third side, completing the inspection process. By adding a rotation function to the worktable, the inspector can not only directly see every flat surface of the leather to be inspected, further improving inspection accuracy, but also avoids redundant operations such as bending over to check the bottom of the leather to be inspected, further reducing the inspector's workload.

[0065] Optionally, the rotating portion 41 may rotate continuously along the third direction at a constant speed, or may rotate only one worktable plane at a time along the third direction under the drive of the second driving portion 42, but the present invention is not limited thereto. Driven by the second driving portion 42, the rotating portion 41 may rotate forward along the third direction or reversely along the third direction, without specific limitation herein.

[0066] In other embodiments, the first driving member 3 further includes a fixed block, through which the first driving member 3 is fixedly connected to the rotating portion 41. During the inspection process, after the leather to be inspected is stretched, the second driving member 4 drives the rotating portion 41 to rotate the first workbench 1, the second workbench 2, and the first driving member 3 together, thereby further facilitating the inspector's inspection of surface defects on the stretched leather.

[0067] In some embodiments, the second driving member 4 further includes a switch portion 44 ; the switch portion 44 includes a foot switch, and the switch portion 44 is configured to be operated to control the opening or closing of the second driving portion 42 .

[0068] Please refer again Figure 3 The foot switch of switch unit 44 is located on the ground. During the inspection process, after the inspector completes the inspection of the first side of the leather to be inspected, they activate the second drive unit 42 by stepping on the foot switch. Driven by the second drive unit 42, the rotating unit 41 rotates the first workbench 1 and the second workbench 2, rotating the leather to be inspected from the first side to the second side, allowing the inspector to continue inspecting the second side. By placing switch unit 44 on the ground, the inspector can flip multiple surfaces of the leather to be inspected by simply stepping on the switch, which helps to make the inspection process more consistent and further improve inspection efficiency.

[0069] In some embodiments, second mounting holes 7 are provided on the outer peripheral surfaces of the first workbench 1 and the second workbench 2, and the leather inspection equipment further includes a plurality of first lighting lamps, which are arranged in the second mounting holes 7 of the first workbench 1 and the second workbench 2 (not shown).

[0070] Please also refer to Figure 1-3 As can be seen from the foregoing, the first and second workbenches 1 and 2 can be regular triangular prism-shaped workbenches, with multiple second mounting holes 7 of equal size spaced apart on the side of each workbench. Each second mounting hole 7 is provided with a first illuminating lamp. During the inspection process, the inspector turns on the first illuminating lamp and checks to see if any light leaks from the surface of the leather being inspected. After the initial inspection is complete, the first illuminating lamp is turned off to further inspect for other defects. By providing multiple first illuminating lamps within the multiple second mounting holes 7 on the outer circumference of the workbench, not only is the space utilization of the workbench plane improved, but it also allows for rapid inspection of the leather being inspected for light leakage defects such as holes and pinholes, and assists the inspector in identifying any missed defects, thereby improving inspection accuracy and efficiency.

[0071] In some embodiments, the second mounting holes 7 on the first workbench 1 and the second workbench 2 include a plurality of them, wherein some of the second mounting holes 7 are provided with a first lighting lamp (not shown), and the leather inspection equipment further includes: a plurality of clips 8, the clip 8 includes a hook portion and a clamping portion 82 connected to the hook portion, the hook 81 of the hook portion is provided in another second mounting hole 7, the clamping portion 82 has a clamping jaw, the upper clamping surface 83 of the clamping jaw is a smooth surface, and the lower clamping surface 84 of the clamping jaw is a serrated surface, and the clamping jaw is configured to clamp the leather to be inspected when the leather to be inspected is stretched along the first direction and / or the second direction.

[0072] Figure 4 This is a schematic diagram of the structure of the clip provided in the embodiment of the present application. Figure 4 As shown, the clamp 8 includes a hook portion and a clamping portion 82 connected to the hook portion. The clamping portion 82 connected to the hook portion has two surfaces at its clamping mouth, the upper clamping surface 83 of the clamping mouth is a smooth surface, and the lower clamping surface 84 of the clamping mouth is a serrated surface. The switch that controls the closing of the clamping portion 82 is a lever structure. When the switch is not closed, the clamping mouth is in a closed state, and the upper clamping surface 83 and the lower clamping surface 84 of the clamping mouth are engaged. When the switch is closed, the upper clamping surface 83 and the lower clamping surface 84 of the clamping mouth are separated, and at this time, it can be used to clamp the leather to be inspected. Before starting the inspection, the inspector clamps the edge of the leather to be inspected with the clamp 8. After preliminarily stretching the leather to be inspected, the clamp 8 is hung in the second mounting hole 7 on the outer peripheral surface of the first workbench 1 and the second workbench 2. During the stretching process of the leather to be inspected, the hook portion of the clamp 8 is tightly hung on the second mounting hole 7, and the clamping portion 82 of the clamp 8 clamps the leather to be inspected. By providing the clip 8 and arranging the clip 8 on the second mounting hole 7, not only can the leather to be inspected be made more stable when arranged on the first workbench 1 and the second workbench 2, but it can also prevent the leather to be inspected from being dislocated and moved during the stretching process of the leather to be inspected, thereby enhancing the fixing ability of the leather to be inspected. In addition, since the upper clamping surface of the clamp is a smooth surface and the lower clamping surface is a serrated surface, it can achieve clamping of the leather to be inspected while avoiding damage to the surface of the leather to be inspected.

[0073] Please refer again Figures 1 to 3 In some embodiments, the leather inspection device 100 further includes a frame, and the first workbench 1, the second workbench 2, the two first driving members 3 and the stretching rod 32 are all disposed in the frame.

[0074] For example, the leather inspection device 100 includes a first workbench 1, a second workbench 2, two first drive members 3, a pull rod 32, and a second drive member 4. The rotating portion 41 of the second drive member 4 (also known as the aforementioned rotating shaft) passes through the first and second workbench 1 and 2. A frame is provided at both ends of the rotating portion 41, and the first workbench 1, the second workbench 2, the two first drive members 3, the pull rod 32, and the second drive member 4 are all mounted within the frame. By providing the leather inspection device with a frame, the workbench can be positioned in a suitable position for inspection personnel, thereby facilitating the inspection work of the inspector.

[0075] In some embodiments, the frame includes a first bracket 61, a second bracket 63, and a third bracket 62 connected in sequence, with the third bracket 62 disposed opposite the first bracket 61. The first bracket 61, the second bracket 63, and the third bracket 62 enclose an installation space; the first workbench 1, the second workbench 2, the two first drive members 3, and the stretching rod 32 are all located in the installation space, with the first workbench 1 disposed on the first bracket 61 and the second workbench 2 disposed on the third bracket 62. The leather inspection device 100 also includes a second lighting lamp 65, which is disposed on the second bracket 63, with the light emitting end of the second lighting lamp 65 facing the first workbench 1 and the second workbench 2.

[0076] Exemplarily, the first workbench 1, the second workbench 2, the two first driving members 3 and the stretching rod 32 of the leather inspection equipment are all suspended in the middle of the installation space surrounded by the first bracket 61, the second bracket 63 and the third bracket 62, and the first bracket 61 is arranged on the left side of the first workbench 1, the first workbench 1 and the first bracket 61 are connected by the bearing portion 43, the third bracket 62 of the frame is arranged on the right side of the second workbench 2, and the second workbench 2 is connected to the third bracket 62 via the second driving portion 42 of the second driving member 4. In the upper part of the installation space, the first bracket 61 and the third bracket 62 are connected by the second bracket 63, and a second lighting lamp 65 facing the first workbench 1 and the second workbench 2 is provided on the second bracket 63. During the inspection process, the inspector can turn on the second lighting lamp 65 set on the second bracket 63 facing the first workbench 1 and the second workbench 2, so that the light of the second lighting lamp 65 is illuminated on the surface of the leather to be inspected, thereby conducting the inspection. By setting up a frame and arranging a second lighting lamp 65 on the frame, not only the stability of the installation of the leather inspection equipment can be improved, but also the first workbench 1 and the second workbench 2 can be illuminated, thereby providing a clearer field of view, which is more conducive to improving the accuracy and efficiency of the inspection and ensuring the accuracy and reliability of the inspection results.

[0077] In other embodiments, the leather inspection equipment includes both a first illumination light (not shown) and a second illumination light 65. During the inspection process, after the leather to be inspected is stretched, the inspector first activates the first illumination light to check for light leakage defects such as holes and pinholes. After turning off the first illumination light, the second illumination light 65 is activated to check for other defects such as cracks, scars, dark scars, and looseness. Providing illumination lights on both the front and back of the leather to be inspected assists the inspector in defect detection, improving inspection accuracy.

[0078] Optionally, the first lighting lamp and the second lighting lamp 65 can be turned on successively or simultaneously; the first lighting lamp and the second lighting lamp 65 can be the same type of lighting lamps or different types of lighting lamps, or lighting lamps specially set according to defects, which are not specifically limited here.

[0079] In some embodiments, a plurality of slide rails 64 are provided on the second bracket 63 , and the second lighting lamp 65 can move along the plurality of slide rails 64 to adjust the position of the second lighting lamp 65 on the second bracket 63 .

[0080] For example, second bracket 63 is equipped with slide rails 64, which include transverse and longitudinal rails. A second illuminating lamp 65 with a sliding bracket is mounted on slide rails 64. During the inspection process, the multiple transverse and longitudinal rails on second bracket 63 allow inspectors to move the second illuminating lamp 65 along the slide rails 64, illuminating the leather under inspection from different angles. This allows inspectors to adjust the position of the second illuminating lamp 65 according to specific needs, facilitating inspection from different angles and improving inspection accuracy.

[0081] In the above embodiment, the leather inspection device 100 further includes a control panel 9. The control panel 9 integrates control switches for multiple components, including the power switch for the leather inspection device 100, the switches for the first through third drive members 3 through 5, and the switches for the first and second lights 65. Providing the control panel 9 on the leather inspection device not only allows inspectors to quickly adjust the device's operating state based on actual needs, but also improves operational convenience by integrating multiple core functions into a single component.

[0082] The following is a brief description of the inspection process using the leather inspection equipment of this application:

[0083] The entire leather inspection process is divided into two parts: one is the leather stretching process, which uses the leather inspection device to stretch the leather to be inspected; the other is the inspection process, which uses the second driving member 4 and the first and second illuminating lamps 65 to complete the inspection. The specific process is as follows:

[0084] During the stretching process, the inspector first lays the leather to be inspected flat and wraps it between the first and second workbenches 1 and 2, with one side of the leather on the first workbench 1 and the other on the second workbench 2. The inspector then clamps the leather with a clamp 8 and secures it to each workbench via hooks 81. The inspector then activates the first and third drive members 3 and 5. The first drive member 3 drives the stretching rods 32 on the side edges of each workbench in the second direction, while the third drive member 5 drives the second workbench 2 away from the first workbench 1 in the first direction. This stretches the leather to be inspected in both the second and first directions, forming three planes for inspection.

[0085] During the inspection process, the inspector first turns on the first light via the control panel 9 to check for light leakage holes in the leather to be inspected. After confirming that there are no light leakage holes, the inspector turns off the first light and turns on the second light 65. The inspector adjusts the direction of the second light 65 so that the light from the second light 65 shines on one of the flat surfaces of the leather to be inspected, and begins inspecting that one side. After confirming that the surface is correct, the inspector steps on the switch 44 to rotate the first and second workbenches 1 and 2 to the other side, and also rotates the flat surface of the leather to be inspected to the other side that has not been inspected. The above process is repeated to complete the inspection.

[0086] During the entire leather inspection process, the leather to be inspected is mechanically stretched by driving the stretching rod 32 through the first driving member 3 and the working table through the third driving member 5, and the rotation of the rotating part 41 is controlled by the switch part 44 provided on the ground, which can reduce the workload of the inspectors and help improve the inspection efficiency. By setting the working table in a prismatic shape and stretching the leather to be inspected by means of multiple stretching rods 32, the leather to be inspected can form multiple flatter inspection planes, which is convenient for the inspectors to observe the leather to be inspected more intuitively. At the same time, the first lighting lamp and the second lighting lamp 65 are provided to assist in the inspection, which can also improve the inspection accuracy and further improve the inspection efficiency.
