[0037] The core of the utility model is to disclose a material feeding device to realize automatic adjustment of the posture of the material during the feeding process.

[0038] Another core of the present invention is to disclose a material detection device including the above-mentioned material feeding device.

[0039] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0040] Combine Figure 1 and Figure 2 The material loading device disclosed in the present invention includes a transmission component 100, a guiding mechanism and a positioning mechanism. The transmission component 100 is used to transmit the material 500. The guiding mechanism is provided on the transmission component 100 and is used to guide the material 500 from its initial posture when it is fed to an intermediate posture. The positioning mechanism is provided on the transmission component 100 and is arranged along the conveying direction ( Figure 2 and Figure 3 The positioning mechanism is provided downstream of the guiding mechanism, and is used to adjust the material 500 from the intermediate posture to the preset posture.

[0041] The material 500 is transmitted at intervals on the transmission component 100. When the material 500 is received on the transmission component 100, the material 500 passes through the guiding mechanism and the positioning mechanism in sequence along the conveying direction of the transmission component 100. At the guiding mechanism, the incoming material 500 with different postures (initial posture) is corrected by the guiding mechanism into an intermediate posture that is convenient for the positioning mechanism to position. When the material 500 continues to be conveyed to the positioning mechanism, the positioning mechanism can position the material 500 and further adjust the material 500 from the intermediate posture to the preset posture, so as to facilitate the subsequent material 500 to be transferred or grasped in a unified preset posture.

[0042] Compared with the existing technology, the material loading device disclosed in the present invention can accurately guide and position the material 500 during the loading process of the material 500, realize automatic adjustment of the posture of the material 500, and ensure the smooth progress of subsequent material detection and other processes.

[0043] Taking the backlight module of material 500 as an example, combined with the Figure 1 One end of the backlight module has a terminal block (or a flexible circuit board or other structure). The guiding mechanism can roughly guide the backlight module to an intermediate posture in which the end with the terminal block is closer to the upstream position and the end without the terminal block is closer to the downstream position. The two sides of the backlight module can cooperate with the positioning mechanism to achieve posture adjustment from the intermediate posture to the preset posture.

[0044] The above-mentioned transmission assembly 100 specifically includes a conveyor belt and a bracket. The material 500 is transported on the conveyor belt, and the conveyor belt is supported on the ground or on a frame by the bracket. The guide mechanism and the positioning mechanism are both set on the bracket and do not affect the conveying of the conveyor belt.

[0045] Combine Figure 1 and Figure 2 In one embodiment, the guiding mechanism includes a guiding bridge 200 and a guiding member 210. The guiding bridge 200 is supported above the transmission assembly 100 and does not affect the transmission assembly 100's conveyance of the material 500. The guiding bridge 200 is provided with a first adjustment slot 201, which is arranged along the extension direction of the guiding bridge 200. The guiding member 210 is adjustably fixed to the guiding bridge 200 via the first adjustment slot 201. The guiding member 210 is used to guide the material 500 to the aforementioned intermediate posture.

[0046] The installation position of the guide member 210 can be adjusted through the first adjustment slot 201, so that the guide member 210 is set on the actual transmission path of the material 500, so that the material 500 in the initial posture can be pushed to the side to adjust it to the intermediate posture. Figure 2, the guiding member 210 can specifically be a rod-shaped member, and the end of the guiding member 210 for pushing the material 500 to adjust its posture is an arc structure to avoid damaging the material 500 during the process of adjusting the posture of the material 500.

[0047] Among them, the guiding bridge 200 is usually arranged perpendicular to the conveying direction of the conveying component 100. The first adjustment groove 201 can be one or multiple arranged in parallel. When there are multiple ones, they can be fixed to different positions of the guiding member 210 respectively to adjust the posture of the guiding member 210.

[0048] In an embodiment, combined with Figure 1 , the guiding member 210 is generally in a shape similar to a "C", and the opening faces the conveying surface of the conveying component 100. Specifically, the guiding member 210 includes a connecting portion and two guiding portions. The connecting portion is adjustably fixed on the guiding bridge 200 through the first adjustment groove 201. The two guiding portions are respectively connected to both ends of the connecting portion and are placed on the conveying surface of the conveying component 100. The guiding portions are used to guide the material 500 from the initial posture to the intermediate posture. Among them, the connecting portion and the guiding portion are usually perpendicularly arranged, and the connecting portion and the guiding portion can be an integral structure and are prepared by bending steel plates or the like.

[0049] In order to ensure the precise positioning of the material 500, in a specific embodiment disclosed in the present utility model, the positioning mechanism includes a coarse positioning component and a fine positioning component. Along the conveying direction of the conveying component 100, the coarse positioning component is arranged upstream of the fine positioning component. Among them, the coarse positioning component is used to perform coarse positioning on the material 500, and the fine positioning component is used to perform fine positioning on the material 500 and adjust it to a preset posture.

[0050] Specifically, the coarse positioning component includes a positioning bridge 300 and two first positioning members 310. The positioning bridge 300 is supported above the conveying component 100 without affecting the conveying of the material 500 by the conveying component 100. The two first positioning members 310 are both arranged on the positioning bridge 300, and the placement angle of the first positioning member 310 on the conveying surface of the conveying component 100 is adjustable. The first positioning member 310 is provided with a guiding surface, and a guiding channel for the material 500 to pass through and guiding the material 500 is formed between the guiding surfaces of the two first positioning members 310. Along the conveying direction of the conveying component 100, the width of the guiding channel gradually narrows ( Figure 1 the first positioning member 310 in

[0051] After the material 500 is guided by the guide 210, it is positioned in an intermediate position, making it easier to pass through the guiding channel and effectively preventing the material 500 from becoming stuck in the channel. Furthermore, during transport within the guiding channel, the guide surface allows the material 500 to further adjust its position. Typically, the width of the guiding channel at its exit is slightly larger than the width of the material 500 (the maximum dimension of the material 500 perpendicular to the conveying direction of the conveyor assembly 100 when the material 500 is in the preset position).

[0052] In order to facilitate the entry and exit of the material 500 in the guiding channel, combined with Figure 1 The end of the guide surface close to the upstream of the conveying direction is an arc-shaped guide structure inclined in the direction opposite to the guide channel. The arc-shaped guide structure can also play a guiding effect on the material 500.

[0053] In order to facilitate the adjustment of the shape and size of the guiding channel according to the material 500, a second adjustment groove 301 is provided on the positioning bridge 300. The second adjustment groove 301 is arranged along the extension direction of the positioning bridge 300. The first positioning member 310 is adjustably fixed to the guiding bridge 200 through the second adjustment groove 301 to be able to adjust the size of the guiding channel. At the same time, the first positioning member 310 can be rotated relative to the second adjustment groove 301 to adjust the shape of the guiding channel.

[0054] The positioning bridge 300 is usually arranged perpendicular to the conveying direction of the transmission assembly 100. The second adjustment slot 301 can be one or multiple second adjustment slots 301 arranged in parallel. When there are multiple second adjustment slots 301, they can be fixed to different positions of the first positioning member 310 to adjust the posture of the first positioning member 310.

[0055] For ease of description, taking the conveying plane of the conveyor belt as a plane reference, the conveying direction of the transmission component 100 is the first direction, and the direction perpendicular to the conveying direction of the transmission component 100 is the second direction.

[0056] In a specific embodiment disclosed in the present invention, the precision positioning assembly includes two sets of push assemblies, combined with Figure 2 The pushing assembly includes a positioning drive 400 and a second positioning member 410. The positioning drive 400 is arranged on the transmission assembly 100, and the second positioning member 410 is arranged at the output end of the positioning drive 400. The positioning drive 400 is used to push the second positioning member 410 to move along the second direction; the second positioning members 410 of the two groups of pushing assemblies are used to push the two sides of the material 500 respectively along the positioning direction under the action of their respective positioning drives 400, and the positioning direction is perpendicular to the conveying direction.

[0057] When the material 500 moves to the position of the precision positioning component, the positioning drive 400 drives the two second positioning components 410 to push the two sides of the material 500 respectively to adjust the posture of the material 500. After the adjustment is completed, the positioning drive 400 drives the second positioning components 410 to retract, and the material 500 continues to be transported to the downstream by the transmission component 100.

[0058] Combine Figure 1 The upstream end of the second positioning member 410 can be configured as an open structure that is open in the upstream direction. During the process of the fine positioning assembly guiding the material 500, the transmission assembly 100 can be stopped or not.

[0059] In another embodiment disclosed herein, the precision positioning assembly includes a positioning plate 430, a lifting drive 420, a positioning drive 400, and a second positioning member 410. The positioning drive 400 and the lifting drive 420 are both disposed on the transmission assembly 100. The second positioning member 410 is disposed at the output end of the positioning drive 400 and is used to push the second positioning member 410 to move in a second direction. The positioning plate 430 is disposed at the output end of the lifting drive 420. The lifting drive 420 is used to drive the positioning plate 430 to move in a direction perpendicular to the conveying plane of the conveyor belt (typically a vertical direction). Specifically, the positioning plate 430 moves between a positioning position and a avoidance position. The material 500 is used to pass between the second positioning member 410 and the positioning plate 430.

[0060] When the material 500 is conveyed to the position where the above-mentioned precision positioning component is located, the positioning plate 430 is driven by the lifting drive 420 to descend toward the positioning position, and the positioning drive 400 drives the second positioning member 410 to move along the second direction toward the direction of the positioning plate 430 until the material 500 is pushed tightly against the plate surface of the positioning plate 430 facing the second positioning member 410, thereby achieving precise adjustment of the material 500. After the adjustment is completed, the positioning plate 430 is raised in the vertical direction by the lifting drive 420 to a avoidance position that does not affect the conveying of the material 500, and the positioning drive 400 synchronously drives the second positioning member 410 to retreat, and the material 500 continues to be conveyed downstream.

[0061] In some embodiments, two sets of guiding mechanisms and positioning mechanisms can be set on a set of transmission components 100 at the same time, and two rows of materials 500 can be transported and positioned at the same time. Figure 3 The positioning plates 430 of the two positioning mechanisms can be shared, and the two columns of materials 500 are staggered and conveyed on the transmission component 100. Correspondingly, the two positioning mechanisms are staggered along the conveying direction. When one material 500 in each of the two columns of materials 500 moves to its respective precision positioning component, the two groups of precision positioning components act simultaneously to position the material 500. After the positioning is completed, the two columns of materials 500 are conveyed to the downstream and transferred in sequence.

[0062] The second positioning member 410 and the positioning plate 430 may both be plate-shaped members, and the lifting driving member 420 and the positioning driving member 400 may both be cylinders.

[0063] To ensure the consistency of the material 500's posture during subsequent inspection processes, the material 500 is typically transferred between the transport assembly 100 (material loading device) and the inspection station using a robotic arm. Therefore, a third positioning member 110 is provided at the downstream end of the transport assembly 100, designed to abut against the material 500. The third positioning member 110 is positioned downstream of the positioning mechanism along the conveying direction of the transport assembly 100. When the material 500 is conveyed by the transport assembly 100 to the location of the third positioning member 110, the material 500 is prevented from moving further due to the influence of the third positioning member 110 (the end of the backlight module without the wiring terminals abuts against the third positioning member 110), allowing the robotic arm to grasp and transfer the material 500. For example, the third positioning member 110 can be a plate-shaped member.

[0064] The transmission assembly 100 is provided with a detection component 120 for detecting whether the material 500 is in a transfer position for transferring the material 500. Specifically, the detection component 120 can be provided on the third positioning member 110 or a bracket of the transmission assembly 100 to detect whether the material 500 has been conveyed to the third positioning member 110. The detection component 120 can be a distance sensor, a photoelectric switch, or an optical fiber.

[0065] In addition, a detection component can be set between the coarse positioning component and the fine positioning component to detect whether there is material at the fine positioning component. When the material is detected, the fine positioning component starts the positioning action. The detection component can be a distance sensor or a photoelectric switch.

[0066] The material detection equipment disclosed in the present invention includes the above-mentioned material feeding device, so it also has the above-mentioned structure and beneficial effects. Other structures refer to the existing technology and are not described here in detail.

[0067] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Specific technical means in some embodiments may be incorporated in part or in whole into another embodiment, unless expressly excluded by another embodiment. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
