Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automated testing equipment, and particularly to a semi-open vibration straight rail fixture for a MEMS product testing device. Background Art
[0002] The current mainstream feeding method for MEMS product testing is vibration disk + vibration straight rail feeding. Since the MEMS is composed of two silicon membranes, its characteristics are very sensitive. The blowing of compressed air will cause the instability or failure of the product sensitivity. Therefore, a non-blowing straight rail is required. The existing straight rail technology uses a closed cover plate and increases the vibration frequency to send the product out under the action of vibration inertia. However, there are some problems in actual production operations that need to be optimized. The closed cover plate cannot directly observe whether there are residual products in the rail during equipment cleaning.
[0003] The thickness of the existing fixture body is 18mm, which is too thick and heavy, and the material cost is relatively high.
[0004] 1. The thickness of this cover plate is 1.5mm, and the width of the middle opening is 0.8mm. Therefore, a connecting structure has to be designed in the middle. When cleaning the machine, products will remain under this position and cannot be found.
[0005] 2. Due to the narrow space factor with a thickness of 1mm and a middle opening width of 0.5mm, environmental light cannot effectively irradiate into the rail, making it difficult to find and not easy to clean. Summary of the Utility Model
[0006] In view of the deficiencies of the prior art, the utility model provides a semi-open vibration straight rail fixture for a MEMS product testing device, which solves the problem that residual products in the rail are not easy to be found and cleaned.
[0007] To achieve the above objectives, the utility model is realized through the following technical solutions:
[0008] A semi-open vibration straight rail fixture for a MEMS product testing device, characterized in that: it includes a straight rail base, a straight rail side plate and a straight rail cover plate. The straight rail base includes a bottom plate and a fixed edge. The fixed edge is fixedly arranged on one side of the upper part of the bottom plate. A straight rail side plate connection hole is arranged on the other side of the upper part of the bottom plate. A straight rail cover plate connection hole is arranged on the upper side of the fixed edge. Straight rail side plate fixing holes are arranged on the straight rail side plate. Straight rail cover plate fixing holes are arranged on the straight rail cover plate. The straight rail side plate is fixedly arranged on the upper part of the bottom plate through fasteners, straight rail side plate fixing holes and straight rail side plate connection holes. The straight rail cover plate is fixedly arranged on the upper part of the fixed edge through fasteners, straight rail cover plate fixing holes and straight rail cover plate connection holes. A rail is arranged between the straight rail side plate and the fixed edge. One side of the straight rail cover plate covers one side above the rail.
[0009] Preferably, the bottom plate and the fixed edge are of an integral structure.
[0010] Preferably, one side of the straight rail cover plate covers two-thirds of the track width.
[0011] Preferably, the fixing holes of the straight rail side plates are oblong holes.
[0012] Preferably, the fixing holes of the straight rail cover plate are oblong holes or round holes.
[0013] Preferably, inclined surfaces are respectively arranged on the upper parts of the inner sides of the straight rail side plates and the straight rail cover plate.
[0014] Preferably, the length of the front end of the straight rail cover plate is shorter than the lengths of the straight rail base and the straight rail side plates.
[0015] Preferably, the materials of the straight rail base, the straight rail side plates and the straight rail cover plate are all DC53 high-strength steel.
[0016] The utility model provides a semi-open vibration straight rail fixture for a MEMS product testing device, which has the following beneficial effects:
[0017] 1. The straight rail cover plate is designed to be semi-open, and environmental light can directly penetrate, so that personnel can clearly observe whether there are residual products in the track at a glance;

Detailed implementation mode
[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] Please refer to Figures 1 - 4 ,
[0027] A semi-open vibration straight rail fixture for a MEMS product testing device, characterized in that it includes a straight rail base 1, a straight rail side plate 2 and a straight rail cover plate 3. The straight rail base 1 includes a bottom plate 11 and a fixed edge 12. The fixed edge 12 is fixedly arranged on one side of the upper part of the bottom plate 11. A straight rail side plate connection hole 13 is arranged on the other side of the upper part of the bottom plate 11. A straight rail cover plate connection hole 14 is arranged on the upper side of the fixed edge 12. A straight rail side plate fixing hole 21 is arranged on the straight rail side plate 2. A straight rail cover plate fixing hole 31 is arranged on the straight rail cover plate 3. The straight rail side plate 2 is fixedly arranged on the upper part of the bottom plate 11 through fasteners 4, the straight rail side plate fixing hole 21 and the straight rail side plate connection hole 13. The straight rail cover plate 2 is fixedly arranged on the upper part of the fixed edge 12 through fasteners 4, the straight rail cover plate fixing hole 31 and the straight rail cover plate connection hole 14. A rail 5 is arranged between the straight rail side plate 2 and the fixed edge 12. One side of the straight rail cover plate 3 covers the upper side of the rail 5.
[0028] The bottom plate 11 and the fixed edge 12 are of an integral structure. One side of the straight rail cover plate 3 covers two-thirds of the width of the rail 5. The straight rail side plate fixing hole 21 is an elongated hole. The straight rail cover plate fixing hole 31 is an elongated hole or a round hole. Inclined surfaces 6 are respectively arranged on the upper parts of the inner sides of the straight rail side plate 2 and the straight rail cover plate 3. The length of the front end of the straight rail cover plate 3 is shorter than the lengths of the straight rail base 1 and the straight rail side plate 2. The materials of the straight rail base 1, the straight rail side plate 2 and the straight rail cover plate 3 are all DC53 high-strength steel.
[0029] In this embodiment, the straight rail base 1 is in the shape of a step. The thickness of the bottom plate 11 is 3.7 mm, the overall width is 16 mm, and the length is 233 mm. The thickness of the fixed side of the product track 12 varies according to the product thickness, and its setting is also different. For example, if the product size is 1.2 mm, the thickness of the track 5 and the fixed side 12 should be 0.1 mm higher than the product to facilitate the passage of the product. If the thickness of the bottom plate 11 is 3.7 mm, the thickness of the fixed side 12 is equal to 3.7 + 1.2 + 0.1 = 5 mm.
[0030] In this embodiment, the thickness of the side plate is 3 mm, and 4 oval openings are designed. M3 screws are used. Loosening the fixing screws can fine-tune the width of the product track 5, with a micro-adjustable movement of about 2 mm.
[0031] In this embodiment, the size of the cover plate varies according to the product size, and its set width and length are also different. For example, the product size is 2.7 mm in length * 1.8 mm in width.
[0032] 1. Length: To enable the product to be smoothly picked up, the front end of the straight rail cover plate 3 cannot completely cover the product. Based on the product length of 2.7 mm, an additional 0.5 mm of leakage is required. The total length of the straight rail is 226 mm, and the length of the straight rail cover plate 3 is equal to 226 - 2.7 - 0.5 = 222.7 mm.
[0033] 2. Width: The product width is 1.8 mm. Based on covering two-thirds as the benchmark, it is equal to the straight rail cover plate 3 needs to cover the product (1.8 / 3) * 2 = 1.2 mm.
[0034] The distance from the edge position of the straight rail base 1 to the track 5 is 5.1 mm. Therefore, the width of the straight rail cover plate 3 is 5.1 + 1.2 = 6.3 mm.
[0035] In this embodiment, the materials of the straight rail base 1, the straight rail side plate 2, and the straight rail cover plate 3 are all DC53 high-strength steel, which is hardened by quenching and tempering processes to a hardness of 62 HRC to ensure that the fixture will not easily deform, bend, and has durability for daily use. The surface is electroplated and polished to remove all burrs and ensure the smoothness and flatness of the track.
[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
