Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1The embodiment of this utility model shown includes a metallographic multi-layer feeding mechanism, comprising a mounting frame 1, a driving assembly 2, a sample storage rack 3, a sample fixture 4, and a visual inspection assembly 5. The mounting frame 1 includes a back plate 11 and a front plate 12, which are arranged parallel to each other and form an operating station 6, a storage station 7, and an inspection station 8. A sliding rail is provided on the opposite side of the back plate 11 and the front plate 12. The sample storage rack 3 is fitted with the sliding rail and can reciprocate between the operating station 6, the storage station 7, and the inspection station 8. The driving assembly 2 is located on the mounting frame 1. On the mounting rack 1, the drive assembly 2 is connected to the sample storage rack 3. The drive assembly 2 drives the sample storage rack 3 to move back and forth between the operation station 6, the storage station 7, and the detection station 8. The sample fixture 4 is set on the sample storage rack 3, on which several samples that need to be fed and tested are arranged. The sample fixture 4 can switch and adjust with the sample storage rack 3 between the operation station 6, the storage station 7, and the detection station 8. The vision inspection assembly 5 is set directly above the detection station 8. When the sample storage rack 3 moves with the sample fixture 4 to the detection station 8, the vision inspection assembly 5 inspects the sample on the sample fixture 4.

[0026] In some embodiments, a plurality of sample storage racks 3 are provided, wherein there can be 1 to 10 sample storage racks 3. Depending on the size of the equipment and actual operating requirements, five sample storage racks 3 are preferably provided. The five sample storage racks 3 are arranged in parallel to each other, and five parallel sliding rails are provided on the opposite side of the back plate 11 and the front plate 12. Each sample storage rack 3 can be equipped with a set of sample fixtures 4, so that multiple sets of samples can be stored at the same time. Each sample storage rack 3 is provided with a set of driving components 2 on its side. The corresponding driving components 2 can synchronously drive the corresponding sample storage rack 3 to switch back and forth between the operation station 6, the storage station 7 and the detection station 8.

[0027] In some embodiments, the width of the front plate 12 is smaller than the width of the back plate 11, wherein the front plate 12 is located at the material storage station 7, and at this time the operation station 6 and the testing station 8 are not obstructed by the front plate 12, which facilitates the staff to pick up and put down the sample fixture 4.

[0028] In the above embodiment, the top of the front plate 12 and the back plate 11 are connected by a top frame 13. The top frame 13 can increase the structural strength and stability of the overall mounting frame 1, and can also further cover the storage station 7, thereby preventing the sample material in the storage station 7 from being damaged by external operating equipment.

[0029] In some embodiments, the two side walls of the sample storage rack 3 are provided with sliding parts that fit into the sliding track, thereby ensuring the stability of the sample storage rack 3 when it reciprocates on the operating station 6, the storage station 7 and the testing station 8.

[0030] Based on this, the sliding rail on the side of the front plate 12 near the back plate 11 adopts a two-way telescopic guide rail, which can meet the needs of supporting and sliding the sample storage rack 3 on the relatively narrow front plate 12.

[0031] In some embodiments, the drive assembly 2 includes a drive motor and a drive screw. The drive screw is horizontally mounted on the mounting frame 1, and the drive motor and the drive screw are connected by a transmission. The drive motor drives the drive screw to rotate forward and backward on the mounting frame 1. A screw sleeve that fits into the drive screw is provided on the sample storage rack 3. When the drive screw rotates forward and backward, it cooperates with the screw sleeve to drive the sample storage rack 3 to reciprocate between the operation station 6, the storage station 7, and the testing station 8. The drive motor is a high-precision servo motor, which can accurately control the speed, number of rotations, and rotation angle of the drive screw, thereby accurately controlling the sample storage rack 3 to stay in any one of the operation station 6, the storage station 7, and the testing station 8.

[0032] In some embodiments, the sample fixture 4 has a plurality of sample slots 41 neatly arranged on it, wherein the outer ring of the sample slots 41 is a shallow groove and the inner ring is a deep groove, so that a plurality of samples can be arranged. A handle 42 is provided on the sample fixture 4 to facilitate the overall movement of the sample fixture 4 by the operator, thereby improving the ease of operation of the sample fixture 4. In order to facilitate the data feedback after the visual inspection component 5 inspects the samples, a corresponding number 43 is provided on the side of each sample slot 41. When the visual inspection component 5 detects that some samples have problems, the operator can quickly determine the position of the corresponding sample slot 41 by using the corresponding number 43.

[0033] In the above embodiment, the sample slots 41 are arranged in eight equally spaced columns, with six sample slots 41 arranged in each column at equal intervals, thus forming a rectangular array layout on one side. This structure can match the viewing angle range of the visual inspection component 5, thereby enabling the visual inspection component 5 to simultaneously take pictures and inspect several arrayed sample slots 41.

[0034] In some embodiments, the visual inspection component 5 includes a visual inspection vertical frame 51, a visual inspection lifting platform 52, a visual inspection drive motor 53, and a detection camera. The visual inspection vertical frame 51 is disposed on the side end of the mounting frame 1. The visual lifting platform is slidably disposed on the visual inspection vertical frame 51 in the vertical direction. The visual inspection drive motor is disposed on the visual inspection vertical frame 51. The visual inspection drive motor 53 is connected to the visual inspection lifting platform 52 in a transmission manner. The visual inspection drive motor 53 can control the vertical height adjustment of the visual inspection lifting platform 52. The detection camera is disposed on the lower end face of the visual inspection lifting platform 52, and the imaging surface of the detection camera faces the detection camera.

[0035] Alternatively, in this solution, a matching slide rail and slide can be set between the vision inspection lifting platform 52 and the vision inspection vertical frame 51. Then, a lifting screw is set in the vertical direction, and a corresponding screw sleeve is set on the vision inspection lifting platform 52. The vision inspection drive motor 53 drives the lifting screw to rotate, thereby moving the vision inspection lifting platform 52 in the vertical direction.

[0036] Alternatively, the detection camera in this solution can be a CDD camera, which is a technology that can be used to take pictures of the sample. The acquired images are then uploaded to the processor, which performs defect detection on the sample to determine the quality of the current batch of samples.

[0037] In use, staff place the sample fixtures 4 containing samples one by one onto multiple sample storage racks 3. After placement, the sample storage racks 3 are moved one by one to the storage station 7. The drive motor is started to drive the drive screw, and the drive screw and screw sleeve work together to control the sample storage rack 3 to move to the inspection station 8. At this time, the sample storage rack 3 with sample fixtures 4 moves directly below the vision inspection component 5. The vision inspection drive motor 53 is started to drive the vision inspection lifting platform 52 to move down. The inspection camera takes pictures of the samples on the sample fixtures 4 and uploads them to the processor. The processor screens the samples and outputs the data and sample number 43 of the screened abnormal samples. Staff re-inspect the abnormal samples. After the test is completed, staff remove and place the sample fixtures 4 as needed.
