[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figures 1 to 5 As shown, the utility model is a conveying device for panel 10 inspection, comprising: a frame 1, on which a detection member 2 is arranged, the detection member 2 is used to detect the processing quality of the panel 10; a conveying mechanism 3, which is arranged on the frame 1, and a loading platform 30 is movably arranged on the conveying mechanism 3, and the loading platform 30 is used to limit the displacement of the panel 10 in the horizontal direction so that the conveying mechanism 3 can transfer the panel 10 to the outside of the detection member 2; a transfer mechanism 4, the transfer mechanism 4 includes a guide block 40 and a transfer frame 41 that can switch between a horizontal posture and an inclined posture, the guide block 40 is installed on the side wall of the loading platform 30; the transfer frame 41 It is connected to the output end of the transfer mechanism 4, and one end of the transfer rack 41 is movably set in the guide block 40, and the other end extends into the loading platform 30. The transfer rack 41 in a horizontal position is set parallel to the loading platform 30, and the transfer rack 41 in an inclined position is set at an angle to the loading platform 30; when the transfer mechanism 4 lifts the transfer rack 41 in a horizontal position, the transfer rack 41 is movably pressed against the bottom wall of the panel 10 to separate the panel 10 from the loading platform 30 in the vertical direction; the transfer rack 41 can switch to an inclined position due to the guide block 40 when continuing to lift, so as to guide the panel 10 from the transfer rack 41 to the external conveyor belt 5.

[0035] This solution is mainly to realize the automatic detection and material transfer operation of the panel 10. Specifically, Figures 1 to 5 As shown, when a worker or a robot places the panel 10 to be inspected on the loading platform 30, the inspection member 2 on the rack 1 can inspect the quality of the panel 10. This method does not require manual intervention, ensuring the consistency and reliability of the inspection results. After the inspection is completed, the conveying mechanism 3 can push the loading platform 30 from the inspection member 2 to the loading platform 30. Figure 1 It should be noted that the transfer rack 41 in this embodiment is in a horizontal position under normal circumstances, that is, after the panel 10 to be inspected is fixed by the stage 30, the transfer rack 41 is at a position between the panel 10 and the stage 30. Therefore, as the output end of the transfer mechanism 4 drives the transfer rack 41 to start lifting upward, the transfer rack 41 (i.e. Figure 3 The transfer rack 41 is arranged parallel to the loading platform 30, so that the transfer rack 41 contacts and supports the bottom of the panel 10 during the lifting process, thereby separating the panel 10 from the loading platform 30 in the vertical direction; as the transfer rack 41 continues to be lifted, due to the limiting effect of the guide block 40 on it in the vertical direction, the transfer rack 41 gradually changes from a horizontal posture to an inclined posture. This change enables the panel 10 to slide along the inclined direction of the transfer rack 41 and finally be transferred to the external conveyor belt 5. It can be seen that the device transfers the panel 10 through a gentle lifting method and an inclined angle design, which reduces the probability of product damage due to improper operation. The compact structural design makes the device take up less space, while improving the overall work efficiency, it also ensures that the quality of the product is not affected.

[0036] The detection part 2 includes a mounting bracket 20 and a detector 21. The mounting bracket 20 is set on the frame 1 and forms a detection cavity 200 together with it, so that the worktable 30 can fix the panel 10 in the detection cavity 200; the detector 21 is detachably connected to the mounting bracket 20 and is used to detect the quality of the panel 10 in the detection cavity 200.

[0037] like Figures 1 to 2 As shown, the mounting bracket 20 in this embodiment is designed in the shape of a semi-arch bridge as a whole. The detection cavity 200 formed by the mounting bracket 20 and the frame 1 enables the conveying mechanism 3 to drive the loading platform 30 to extend into the detection cavity 200, so that the detector 21 can detect the panel 10 on the loading platform 30. The detection cavity 200 can provide sufficient placement space for stable detection of the panel 10, avoiding position interference between the panel 10 and the mounting bracket 20, or even collision damage. Not only that, relying on the detachable design of the detector 21, cleaning, replacement or upgrading becomes simple and quick, reducing maintenance costs and improving the availability of the equipment. It should be noted that the detector 21 in this embodiment can be a visual camera, a laser scanner or other high-precision detection equipment for detecting the size, color and surface defects of the product, which not only reduces the need for manual intervention, but also significantly improves the speed and efficiency of the production line.

[0038] A vertical guide groove 400 and a horizontal guide groove 401 are provided in the guide block 40. The horizontal guide groove 401 is connected to the top of the vertical guide groove 400. The end of the transfer frame 41 is connected to a guide column 410. The guide column 410 is movably set in the vertical guide groove 400 or the horizontal guide groove 401.

[0039] like Figures 3 to 5 As shown, when the panel 10 is detected by the detector 21, and the loading platform 30 is pushed to the Figure 1 When the transfer rack 41 is in the position shown, the output end of the transfer mechanism 4 can drive the transfer rack 41 to be lifted. Since the guide column 410 on the transfer rack 41 is movably connected to the vertical guide groove 400, the transfer rack 41 in a horizontal posture contacts the bottom of the panel 10 and lifts it to the outside of the loading platform 30 under the guidance of the vertical guide groove 400. It is worth noting that at this time the guide column 410 reaches the top of the vertical guide groove 400 and connects with the horizontal guide groove 401; as the transfer rack 41 is further lifted, due to the action of gravity and the mechanical structure design, the transfer rack 41 will go around the guide column 410 along Figure 3 or Figure 4 Rotate clockwise, and the guide post 410 will automatically enter the horizontal guide slot 401 (ie Figure 5 The state shown in FIG4 is to ensure the stability of the transfer rack 41 during the process of changing from a horizontal posture to an inclined posture. For this reason, the transfer rack 41 switches to the inclined state (ie Figure 5 The transfer rack 41 relies on the cooperation of the right end guide column 410 and the horizontal guide groove 401 to ensure the smoothness and stability of the panel 10 when it slides down the inclined direction of the transfer rack 41 to the conveyor belt 5, thereby avoiding the panel 10 from falling off and being damaged due to vibration of the transfer rack 41 in the inclined state.

[0040] The transfer mechanism 4 also includes a driving member 42 and a guide member 43. The driving member 42 is installed on the frame 1 and is used to drive the guide member 43 to lift in the vertical direction; a movable seat 430 is provided on the guide member 43, and a connecting shaft 411 is installed on the transfer frame 41, and the connecting shaft 411 movably passes through the movable seat 430.

[0041] like Figures 3 to 5 As shown, when the stage 30 moves the guide 43 and the panel 10 after inspection to Figure 1 When the guide member 43 is in the position shown, the guide member 43 is located directly above the movable end of the driving member 42. As the driving member 42 drives the guide member 43 to rise in the vertical direction, the movable seat 430 on the guide member 43 moves synchronously along the vertical direction. Figure 3Move vertically upward. Since the transfer rack 41 is close to the above-mentioned guide block 40 and is movable through the movable seat 430 through the connecting shaft 411 (that is, the rotating rack is hinged to the movable seat 430), when the movable seat 430 rises, the transfer rack 41 in a horizontal posture will also rise accordingly. At the same time, the guide column 410 at the end of the transfer rack 41 can slide in the vertical guide groove 400 to ensure that the transfer rack 41 stably contacts the bottom of the panel 10 in a horizontal posture, thereby freeing the panel 10 from the restriction of the loading platform 30, providing a guarantee for the stability of the subsequent transfer rack 41 when tilting to achieve panel 10 unloading.

[0042] The guide member 43 also includes a driving block 431 and a guide column 432. The driving block 431 is located above the output end of the driving member 42, and the guide columns 432 are detachably connected to both ends of the driving block 431; a fixed guide sleeve 300 is installed on the stage 30, and the top of the guide column 432 passes through the fixed guide sleeve 300 and is connected to the bottom wall of the movable seat 430.

[0043] Further, if Figures 3 to 5 As shown, the guide member 43 in this embodiment also includes a driving block 431 and a guide column 432, wherein the driving block 431 is mainly used to increase the contact area when the output end of the driving member 42 drives the guide column 432, to avoid jamming between the two and affecting the smoothness of the subsequent panel 10 transfer; and the fixed guide sleeve 300 can effectively limit the moving path of the guide column 432, so that the moving seat 430 connected to the top of the guide column 432 becomes more stable when pushing the transfer frame 41 to lift, reducing the possibility of lateral shaking during movement, and ensuring the accuracy and stability of the transfer frame 41 when moving up and down.

[0044] Preferably, since the switching between the horizontal posture and the tilted posture of the transfer frame 41 in this embodiment requires the mutual cooperation between the guide block 40 and the moving seat 430, the axis of the guide column 432 is arranged to be non-coplanar with the axis of the connecting shaft 411, such as Figures 3 to 5As shown, because the moving seat 430 always relies on the guide column 432 to move back and forth in the vertical direction, in order to convert the displacement of the moving seat 430 in the vertical direction into the tilting rotation of the transfer frame 41 relative to the guide block 40, on the one hand, the above-mentioned horizontal guide groove 401 and the guide column 410 are used for the card fit, and on the other hand, the point where the guide column 432 drives the moving seat 430 to lift is staggered with the hinge of the transfer frame 41 relative to the moving seat 430 (that is, the axis of the connecting shaft 411). When it is lifted to the position where the guide column 410 is engaged with the top of the vertical guide groove 400, as the moving seat 430 continues to lift, the transfer frame 41 can be rotated around the connecting shaft 411, and the guide column 410 can be slid into the horizontal guide groove 401 during the switching of the tilt state, thereby ensuring the stability of the transfer frame 41 during the guide panel 10 sliding to the conveyor belt 5; it is precisely because of the staggered setting of this structure that the jamming phenomenon between the moving seat 430 and the transfer frame 41 during the lifting process is effectively avoided, thereby affecting the smoothness when switching the tilt state.

[0045] It should be added that, since the stage 30 needs to be Figure 1 The guide sleeve 300, the guide post 432 and the movable seat 430 are all mounted on the stage 30, so these structures will inevitably move synchronously with the stage 30. In order to reduce the overall weight, the output end of the driving member 42 in this embodiment is designed to be non-contact with the driving block 431, that is, the driving member 42 does not move back and forth with the stage 30 on the frame 1, and at the same time, when the stage 30 moves to Figure 1 In the position shown, the driving block 431 is just above the output end of the driving member 42, and the normal switching operation of the transfer frame 41 between the horizontal posture and the inclined posture can be successfully completed.

[0046] The movable seat 430 includes a mounting portion 430a and a raised portion 430b. The mounting portion 430a is symmetrically arranged on both sides of the raised portion 430b, and is used to connect the guide column 432 to the mounting portion 430a through fasteners; the transfer frame 41 is composed of two support frames 412 connected by a connecting shaft 411, and the two support frames 412 are movably attached to the side walls of the raised portion 430b.

[0047] Preferably, if Figure 3 and Figure 4As shown, the movable seat 430 in this embodiment is composed of a protrusion 430b and mounting portions 430a located on both sides of the protrusion 430b, wherein the mounting portion 430a is mainly used to connect the movable seat 430 as a whole with the top of the above-mentioned guide column 432, to ensure that the guide column 432 drives the movable seat 430 to be lifted smoothly in the vertical direction, to avoid the movable seat 430 from shaking or tilting during the lifting process, and to cause the transfer frame 41 to be stuck when moving; and the protrusion 430b is used to realize the movable connection with the transfer frame 41. When the two support frames 412 are respectively movably attached to the two side walls of the protrusion 430b (as shown in FIG. Figure 3 The state shown in the figure) can be achieved by passing the connecting shaft 411 through the protrusion 430b and the support frame 412, and finally realizing the installation mode in which the transfer frame 41 is movably hinged to the protrusion 430b. During the continuous lifting of the moving seat 430, this structure can, on the one hand, utilize the support frame 412 to stick to the side wall of the protrusion 430b to ensure that the transfer frame 41 stably lifts the panel 10 in a horizontal posture. On the other hand, during the process of switching the transfer frame 41 to the inclined posture, the two support frames 412 are movably pressed against and rotated along the side wall of the protrusion 430b, ensuring that the posture conversion of the transfer frame 41 is smooth.

[0048] It should be noted that the detachable connection referred to in this embodiment and the above-mentioned fastener structure can be replaced by other connecting components such as screws.

[0049] Several support columns 301 are symmetrically distributed around the periphery of the top wall of the loading platform 30 . Positioning pins 301 a are formed on any two diagonally placed support columns 301 . Positioning holes 100 are formed on the panel 10 , and the positioning pins 301 a are movably inserted into the positioning holes 100 .

[0050] like Figure 4 As shown, in this embodiment, four support columns 301 distributed in a rectangular shape are used. During the inspection process, workers or robots can place the workpiece to be inspected on the support columns 301, and rely on the positioning pins 301a on the support columns 301 to be inserted into the positioning holes 100. While playing a positioning and limiting function for the panel 10 to be inspected, it effectively avoids the shaking that may occur during the inspection process; at the same time, the support columns 301 of the same height can be used to ensure that the panel 10 is stably placed in a horizontal posture, which provides a guarantee for the accuracy of the detector 21 in inspecting the quality of the panel 10.

[0051] The conveying mechanism 3 includes: a driving cylinder 31, which is arranged on the frame 1, and the output end of the driving cylinder 31 is connected to the driving shaft 310; a mounting block 302 is provided on the worktable 30, and the driving shaft 310 is connected to the mounting block 302; a slide rail 33 and a slider 32, the slide rail 33 is provided on the frame 1, the top wall of the slider 32 is connected to the worktable 30, and the bottom of the slider 32 is movably connected to the slide rail 33, which is used to drive the worktable 30 to move back and forth on the frame 1.

[0052] like Figures 1 to 3 As shown, in this embodiment, the output end of the driving cylinder 31 is connected to the mounting block 302 on the side wall of the stage 30, thereby realizing the stage 30 in the above-mentioned detection cavity 200 and Figure 1 The platform 30 moves back and forth between the positions shown in the figure. During this process, the cooperation of the slider 32 and the slide rail 33 further provides a stable guiding effect for the movement of the platform 30, so that the platform 30 can move smoothly in the horizontal direction, avoiding unnecessary vibration and shaking, and improving the overall stability of the structure. Moreover, the structure replaces the manual handling of the panel 10, effectively avoiding scratches, indentations or other forms of physical damage caused by improper handling, and ensuring that the quality of the panel 10 is not affected.

[0053] It should be noted that the driving member 42 and the driving cylinder 31 in this embodiment can be replaced by other driving devices such as hydraulic cylinders and cylinder drives.

[0054] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0056] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
