[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1 to 6 As shown, this utility model provides a multi-station turntable 11 inspection mechanism, including: a frame 100, on which a turntable 11 is provided. The turntable 11 is driven to rotate by a motor. Multiple carriers 200 for carrying workpieces are distributed in a ring on the turntable 11. Each carrier 200 is respectively equipped with a feeding component 300 for positioning and cooperating with the carrier 200.

[0029] The feeding assembly 300 includes: a first driving component 31 mounted on the frame 100; the first driving component 31 has a workpiece-adsorbing end 32; the first driving component 31 includes a linear module that drives horizontally in the transverse direction; the linear module has a cylinder that drives vertically; a motor is connected to the driving end of the cylinder; and the workpiece-adsorbing end 32 is connected to the motor. (See reference...) Figure 2 As shown, the material handling end 32 includes: a rotating block 321, on which a plurality of suction cup seats 322 protruding from its surface are arranged in an array, and the suction cup seats 322 in each row are spaced apart. A plurality of limiting blocks 323 are spaced apart between two arrays of suction cup seats 322, and each pair of limiting blocks 323 constitutes a work station.

[0030] The first driving component 31 drives the picking end 32 to move to the position where the workpiece is to be loaded on one side of the loading assembly 300. At this time, the suction cup seat 322 is located above the workpiece at the corresponding position. (See reference...) Figure 5 As shown, the two ends of the workpiece are adsorbed onto the suction cup seat 322, while the two side edges of the workpiece are stuck between the two limiting blocks 323. Moreover, the height of the suction cup seat 322 is lower than the height of the limiting blocks 323, which ensures the stability of the workpiece during transfer and avoids the risk of the workpiece falling.

[0031] In addition, see Figure 3 As shown, the carrier 200 includes: a carrying platform 21 disposed on the carrier 200, positioning grooves 22 that cooperate with the limiting block 323 are provided on both sides of the carrying platform 21, and a groove 23 is provided in the middle position of the carrying platform 21; a notch 24 corresponding to the carrying platform 21 is provided on the carrier 200.

[0032] The workpiece adsorbed by the picking end 32 is transferred to the corresponding position above the carrier 200 by the first driving member 31. Then, the first driving member 31 drives the picking end 32 to move downward a certain distance, so that the workpiece is mounted on the support platform 21. At the same time, when the workpiece is placed on the support platform 21, the limiting block 323 on the picking end 32 is inserted into the positioning groove 22, so that the workpiece can fall accurately onto the support platform 21, improving the accuracy of workpiece loading. Moreover, the middle position of the support platform 21 is empty, that is, the bottom of the workpiece is hollow, and its edge is mounted on the support platform 21, reducing the contact between the workpiece and the surface of other components, improving the surface quality of the workpiece.

[0033] After the workpiece is fed through the feeding assembly 300, the motor drives the turntable 11 to rotate, so that the carrier 200 and the workpiece are transferred to the corresponding position of the top surface detection assembly 400 for detecting the top surface and size of the workpiece. The top surface detection assembly 400 includes: a top surface scratch detection unit 41 set on the frame 100 for detecting scratches on the top surface of the workpiece, and a top surface size detection unit 42 for detecting the appearance size of the top surface of the workpiece.

[0034] When the workpiece moves to the top surface scratch detection unit 41, it is checked whether there are scratches or defects on the top surface of the workpiece. After the top surface scratch detection unit 41 has finished its detection, the workpiece is moved to the top surface dimension detection unit 42, which detects the length, width, height and other dimensions of the workpiece.

[0035] After the top surface dimension detection unit 42 completes its detection, the workpiece is transferred to the side detection assembly 500 for detecting the workpiece's side surface dimensions. The side detection assembly 500 includes a side detection unit 51 mounted on the frame 100 for detecting the side surface dimensions of the workpiece. (See reference...) Figure 4 As shown, the bottom surface of the workpiece is provided with steps. The side detection unit 51 is used to detect the length, width, height of the side surface of the workpiece and whether the bottom surfaces of the steps at both ends are aligned.

[0036] See Figure 6 As shown, after the side inspection unit 51 completes its inspection, the workpiece is transferred to the first flipping assembly 600 for clamping and flipping the workpiece. The first flipping assembly 600 includes: a second drive member 101 with four degrees of freedom mounted on the frame 100, and grippers mounted on the second drive member 101. The second drive member 101 drives the grippers to move at the notch 24 of the carrier 200, clamping the edge of the workpiece and flipping it so that the bottom surface of the workpiece faces upwards to meet the inspection requirements of the next process. The second drive member 101 includes a first cylinder 1011 mounted on the frame 100, a slide plate 1012 slidably mounted on the frame 100, the slide plate 1012 being driven to move by the first cylinder 1011, a second cylinder 1013 mounted on the slide plate 1012 driving the vertical movement of a moving plate 1015, a motor 1014 mounted on the moving plate 1015, and a third cylinder 1016 mounted on the drive end of the motor 1014 driving the movement of the grippers.

[0037] After the workpiece has been flipped over for the first time, it is transferred to a bottom surface inspection assembly 800 for inspecting the bottom surface and dimensions of the workpiece. The bottom surface inspection assembly 800 includes a bottom surface scratch inspection unit 81 mounted on the frame 100 for inspecting scratches on the bottom surface of the workpiece, and a bottom surface dimension inspection unit 82 for inspecting the appearance dimensions of the bottom surface of the workpiece. The bottom surface scratch inspection unit 81 and bottom surface dimension inspection unit 82 described above use the same inspection method as the top surface scratch inspection unit 41 and top surface dimension inspection unit 42, and will not be described in detail here.

[0038] After the workpiece top surface dimension detection unit 42 finishes detection, the workpiece is transferred to the second flipping component 700 for clamping the workpiece and flipping it a second time. The principle of the second flipping component 700 is the same as that of the first flipping component 600, and will not be described in detail here. The second flipping component 700 is used to flip the top surface of the workpiece to face upwards again to meet the requirements of subsequent workpiece unloading.

[0039] After the workpiece has been flipped a second time, it is transferred to the unloading assembly 900 for unloading the inspected workpiece. The unloading assembly 900 includes a third drive unit 92 mounted on the frame 100, and the third drive unit 92 has an unloading end 91 for adsorbing the workpiece. The third drive unit 92 operates on the same principle as the first drive unit 31, and will not be described in detail here. The unloading end 91 adsorbs and transfers the inspected workpiece to the workpiece placement position located on one side of the unloading assembly 900. If the inspected workpiece is unqualified, the unloading end 91 transports the workpiece into the box for collection.

[0040] The aforementioned top surface scratch detection unit 41, top surface dimension detection unit 42, side surface detection unit 51, bottom surface scratch detection unit 81, and bottom surface dimension detection unit 82 are all detected by an industrial automated vision inspection camera.

[0041] In this embodiment, based on the detection components corresponding to the carrier 200, the surface and dimensions of the workpiece can be inspected in all directions, improving detection efficiency and accuracy.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily 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. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
