In order to avoid interference and influence from factors such as ambient light, the inspection platform of the visual inspection equipment generally needs to be installed inside the inspection shell. When inspectors take and place products, they need to bend down frequently, resulting in high work intensity and inconvenient and labor-saving operation. Summary of the invention

[0035] See Figures 1 to Figure 3 , is a visual inspection device 100 shown in an embodiment of the present application, which is applied to a working environment for visual inspection of the appearance quality of an electronic product 200. For example, the electronic product 200 can be various types of LED products, etc.

[0036] Exemplarily, the visual inspection device 100 includes an inspection base 10 , a visual inspection camera (not shown in the figure), a shifting assembly 20 , an inspection platform 30 , and an inspection bracket 50 .

[0037] The detection seat 10 is set as an open frame structure, specifically including support legs and a frame body, and the frame body is installed above the support legs. An inspection station 11 is arranged inside the detection seat 10. The inspection station 11 is specifically an internal concave cavity of the frame body, and an entry and exit opening is arranged on the side of the frame body facing the inspection personnel, so that the inspection platform 30 and the inspection bracket 50 can enter the inspection station 11 or exit the inspection station 11 and move to the outside of the detection seat 10.

[0038] The visual inspection camera is installed on the frame body and is located above the inspection station 11. When the electronic product 200 to be inspected enters the inspection station 11, it is just below the visual inspection camera, thereby facilitating the visual inspection operation.

[0039] The shifting component 20 is arranged on the detection seat 10; the detection platform 30 is connected to the shifting component 20, and the detection platform 30 is provided with a positioning structure 40; the detection bracket 50 is arranged on the detection platform 30 and is positioned and cooperated with the positioning structure 40. The detection platform 30 can drive the detection bracket 50 to enter the detection station 11 or exit the detection station 11 and move to the outside of the detection seat 10 under the drive of the shifting component 20. The detection bracket 50 is used to load the electronic product 200 to be detected.

[0040] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: when the visual inspection device 100 of this solution is working, the shift component 20 first drives the inspection platform 30 to withdraw from the inspection station 11 inside the inspection seat 10, and the inspection platform 30 drives the inspection bracket 50 to move to the outside of the inspection seat 10, so that the inspection personnel can place the electronic product 200 to be inspected on the inspection bracket 50 without bending down, and then the shift component 20 drives the inspection platform 30 and the inspection bracket 50 to return to the inspection station 11, so that the electronic product 200 to be inspected enters the inspection station 11 to accept the inspection operation; when the inspection is completed, the shift component 20 drives the inspection platform 30 and the inspection bracket 50 to move and exit with the inspected electronic product 200 to the outside of the inspection station 11 again, and the inspection personnel can also directly take out the electronic product 200 without bending down. That is, the visual inspection device 100 of this solution has a higher degree of automation than the prior art, which can significantly reduce the work intensity of the inspection personnel and make the inspection operation more convenient and labor-saving.

[0041] It is necessary to explain that in the present application, when the electronic product 200 to be inspected is an LED product, the inspection bracket 50 is specifically provided with contacts or slots, and the LED product is mounted on the inspection bracket 50, and its electrical contact end can form an electrical connection with the contacts or slots, so that the inspection bracket 50 supplies power to the LED product so that the LED product can light up normally, thereby facilitating visual inspection.

[0042] Please continue to refer to Figures 1 and 2. In some embodiments, the detection seat 10 is provided with a work surface, and the work surface is horizontally arranged. The shift assembly 20 includes two shift actuators 21 for outputting telescopic linear power, and the two shift actuators 21 are both installed on the work surface, and one of the shift actuators 21 is connected to one end of the length direction of the detection platform 30, and the other shift actuator 21 is connected to the other end of the length direction of the detection platform 30.

[0043] Two shift actuators 21 are used to connect the two ends of the detection platform 30 in the length direction respectively, so as to form a stable support for the detection platform 30 on both sides. When the two shift actuators 21 output linear force synchronously and in the same direction, they can drive the detection platform 30 and the detection bracket 50 as well as the electronic product 200 to be detected installed on the detection bracket 50 to move horizontally into the detection station 11 or move horizontally out of the detection station 11.

[0044] Alternatively, as an alternative to the above-mentioned embodiment, in other embodiments, the detection seat 10 is provided with a work surface, the shift assembly 20 includes at least one guide rail unit and a shift actuator 21 for outputting telescopic linear power, the guide rail unit is connected between the work surface and the end of the length direction of the detection platform 30, and the shift actuator 21 is connected to the middle or near the middle of the detection platform 30.

[0045] A single shift actuator 21 is used to connect with the detection platform 30 at the middle or near the middle position, which can also meet the needs of driving the detection platform 30 and the detection bracket 50 as well as the electronic product 200 to be detected mounted on the detection bracket 50 to enter and exit the detection station 11, while reducing the number of shift actuators 21 used and reducing the space occupied on the work surface; on this basis, the additional guide rail unit guides and limits the movement of the detection platform 30, thereby improving the stability of the movement of the detection platform 30.

[0046] Optionally, the guide rail unit is composed of a rail body and a rail groove member. The rail body can slide back and forth in the groove cavity of the rail groove member.

[0047] Optionally, the displacement actuator 21 may be any one of a cylinder, a linear motor, an electric push rod, and the like.

[0048] Please continue to refer to Figure 2. In the present application, the detection bracket 50 and the detection platform 30 are two independent components. Therefore, in order to make the detection bracket 50 firmly installed on the detection platform 30 and reduce the structural composition and operation difficulty of the positioning structure 40, in some embodiments, the positioning structure 40 includes a positioning member 41 and a positioning hole opened on the detection platform 30. The positioning member 41 is inserted into the positioning hole and abuts against the side of the detection bracket 50.

[0049] Specifically, the positioning member 41 can be a latch, a bolt, etc. Taking a latch as an example, the end of the latch passes through the positioning hole and extends to the side of the detection bracket 50, so that it can abut against the side of the detection bracket 50 to form a lateral limit for the detection bracket 50. This positioning method and structure are simple and highly feasible.

[0050] Generally, when the LED product is replaced with a different specification and size, it is also necessary to replace the detection bracket 50 of a corresponding different size accordingly. Therefore, the positioning member 41 is required to be able to adapt to the size change of the detection bracket 50 and to be able to move flexibly on the detection platform 30 to meet the need for positioning the detection brackets 50 of different sizes. Therefore, on the basis of the above embodiment, the positioning member 41 includes a first positioning member and a second positioning member, and the positioning hole includes a first long slot hole 42 extending along the X-axis direction and a second long slot hole 43 extending along the Y-axis direction. The first positioning member is inserted into the first long slot hole 42 and can slide in the first long slot hole 42. The second positioning member is inserted into the second long slot hole 43 and can slide in the second long slot hole 43. The first positioning member and the second positioning member respectively abut against different sides of the detection bracket 50.

[0051] Please continue reading Figure 3 In particular, when only one first long slot and one second long slot are provided respectively, and the lengths of the first long slot and the second long slot should not be processed too long, so that the adjustment stroke cannot meet the movement requirements of the positioning member 41, and thus the detection bracket 50 cannot be effectively positioned, it is possible to select at least two first long slot holes 42, at least two first long slot holes 42 are arranged at intervals along the Y-axis direction of the detection platform 30, and the first positioning member can be assembled with any first long slot hole 42. Further, at least two second long slot holes 43 are provided, at least two second long slot holes 43 are arranged at intervals along the X-axis direction of the detection platform 30, and the second positioning member can be assembled with any second long slot hole 43.

[0052] Taking a top corner of the detection platform 30 as a reference point, at least two second long slot holes 43 arranged at intervals along the X-axis and at least two first long slot holes 42 arranged at intervals along the Y-axis are at different distances from the reference point. When the size of the detection bracket 50 is small or large, and the single first long slot hole 42 and the second long slot hole 43 are not sufficient to meet the adjustment requirements, the first positioning member and the second positioning member can be selected to be combined with the first long slot hole 42 and the second long slot hole 43 that are closer to or farther away from the reference point, which can well solve the above problem.

[0053] In order to more conveniently position the detection bracket 50 to the detection platform 30, in other embodiments, the positioning structure 40 includes a magnetic component, which is movably disposed on the detection platform 30 and is magnetically fixed to the detection bracket 50; or, the positioning structure 40 includes a magnetic component and a magnetic matching component, one of which is movably disposed on the detection platform 30, and the other of which is disposed on the detection bracket 50, and the magnetic component and the magnetic matching component are magnetically fixed.

[0054] Optionally, the magnetic attraction member may be a magnet, and the magnetic attraction matching member may be a component made of metal or other materials that can be magnetically connected to the magnet, such as an iron sheet.

[0055] In addition, based on any of the above embodiments, the visual inspection device 100 also includes a safety inspection component 60 , which is disposed on the inspection seat 10 and located on one side of the inspection platform 30 , and the safety inspection component 60 is electrically connected to the displacement component 20 .

[0056] In actual work, when the inspector's hand extends into the inspection station 11 to operate, the safety detection component 60 detects the presence of the hand, and then issues an alarm prompt, and at the same time issues an instruction to stop the shift component 20 from working, thereby avoiding pinching the inspector and eliminating potential safety hazards.

[0057] Specifically, the safety detection component 60 includes a bracket 61 and a safety grating 62, the bracket 61 is arranged on the detection seat 10, the safety grating 62 is installed on the bracket 61 and is opposite to the detection platform 30, and the safety grating 62 is electrically connected to the displacement component 20. The safety detection component 60 has a simple structure and low manufacturing cost, and the safety grating 62 has high detection sensitivity and accuracy.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
