Then, the lifting slide cylinder 32 is driven to press the positioning structure pressure strip 33 downward, and the positioning pins 34 are used to determine the position of the chip 60.
[0031] The second transfer mechanism 40 includes a second bracket 41, a second transfer screw module 42, a second lifting slide 43, and a second limit clamping double-axis cylinder 44.

[0033] The two sets of limiting and fixing mechanisms 30 are arranged facing each other on both sides of the processing positions of the conveying track 10 corresponding to the positioning hole grooves. The first moving mechanism 20 is located on one side of the starting end of the conveying track 10 and extends backward. The second moving mechanism 40 is located on the other side of the conveying track 10. The end of the track of the first moving mechanism 20 and the initial end of the track of the second moving mechanism 40 have an overlapping area, and the end of the track of the second moving mechanism 40 and the initial end of the track of the third moving mechanism 50 have an overlapping area.
[0034] In specific implementation, the initial section of the conveying track 10 is provided with positioning frames at both ends corresponding to the length direction of the chip, specifically a starting positioning frame 70 and a guide positioning frame 80. The middle horizontal plate 71 of the starting positioning frame 70 is provided with an inwardly concave notch 72, and the middle horizontal plate 81 of the guide positioning frame 80 is provided with a guide through notch 82, which allows the initial placement of the chip 60 to be initially positioned and ensures the first transfer mechanism 20 to move the chip 60;

[0036] The second transfer screw module 41 of the second transfer mechanism 40 is a two-stage moving module. The first stage of the second transfer screw module 41 moves the chip 60 to the corresponding position of the conveying track 10 at the processing position of the positioning hole groove. The second stage of the second transfer screw module 41 moves the chip 60 to the rear area.
[0037] The end of the conveying track 10 is provided with a stop protrusion 13 of the chip 60, and the stop protrusion 13 is used to position the end of the chip 60;
[0038] The push rod 54 of the third transfer mechanism 50 is in the ascending state, positioning the end of the chip 60 to the stop protrusion end 13, completing the feeding operation;
[0039] A plurality of rebound pressure blocks 35 are arranged along the length direction on the inner side of the positioning structure pressure strip 33 of the limiting fixing mechanism 30 . The rebound pressure blocks 35 are used to prevent the chip 60 from being stuck and lifted when the positioning PIN needle 34 is separated from the chip 60 .
[0040] Its working principle is as follows: the first transfer mechanism can perform different types of inspection and processing operations; the second transfer mechanism is a transition transfer mode; the limiting and fixing structure can perform precision processing and inspection on the chip, which is convenient for the external processing mechanism to perform positioning hole groove processing on the chip; the third transfer mechanism performs material receiving operations on the product; the loading mechanism takes the sheet chip and places it on the initial loading position of the conveyor track, and then transfers the product through the first transfer mechanism. After the first stage of transfer processing is completed, the second transfer mechanism performs a second transfer processing on the product and then moves the product to the positioning hole groove processing position. The limiting and fixing mechanisms on both sides position the chip, and then it is processed by the external mechanism. After positioning processing, the second transfer mechanism pushes the product to the third stage of transfer position, and then the chip is transferred to the unloading position through the third transfer mechanism.
[0041] Its beneficial effects are as follows:
[0042] 1. The first, second and third transfer mechanisms are all moved by ball screw modules, with high repeatability, stable operation and long service life.
[0043] 2. The conveyor track is an open track. The product transfer abandons the traditional PIN needle hooking of the product for support and movement. Instead, the product is transferred by parallel wrapping. The product is not clamped to prevent deformation, but only the position of the product is restricted, which greatly improves the smoothness of its passage.
[0044] 3. The device is equipped with a limited fixing mechanism, which can perform precision testing or precision processing;
[0045] 4. The conveyor track has high compatibility and the middle part of the track is hollowed out, which allows for double-sided processing or visual inspection of products.
[0046] 5. The conveying tracks are designed to fit the size of the chip itself. The friction, contact area and activity gap are small during product transportation, which makes it difficult for the chip to be scratched, defective or dropped.
[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
[0048] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
