Technical Field
[0001] This utility model relates to the field of chip packaging technology, and in particular to an automatic adjustment device for the levelness of a chip placement machine track. Background Technology
[0002] The levelness of the chip placement machine track is one of the main causes of chip placement voids and chip breakage. Therefore, the levelness of the track needs to be adjusted during routine maintenance and after replacing different chips. Currently, the industry standard for adjusting the levelness of chip placement machine tracks is to manually turn the set screws. However, manual adjustment has many uncontrollable factors and takes a long time, which seriously restricts production efficiency.
[0003] Based on the above-mentioned technical problems, this application proposes an automatic adjustment device for the track level of a chip placement machine. Utility Model Content

The track is bolted to the base plate, and the base plate has several adjusting holes located within the vertical projection of the track onto the base plate. The adjusting mechanism is installed on the lower side of the base plate and has a lifting rod that passes through the adjusting holes and abuts against the lower end face of the track. The measuring mechanism is installed above the track and is used to measure the height difference between the upper end faces of the track. The adjusting mechanism automatically adjusts the lifting height of the lifting rod according to the height difference.
[0006] Furthermore, the adjustment mechanism is a fixed-shaft motor, and the lifting rod is fixed to the output end of the fixed-shaft motor.
[0007] Furthermore, two connecting holes are provided on the track, which are symmetrically distributed on both sides of the track centerline; threaded holes corresponding to the connecting holes are provided on the base plate, and bolts are threaded through the connecting holes and screwed into the threaded holes.
[0008] Furthermore, several adjustment holes are symmetrically arranged on both sides of the centerline of the track.
[0009] Furthermore, the measuring mechanism is a laser altimeter.
[0010] The technical solutions provided in this application have at least the following technical effects or advantages:
[0011] The height difference at different positions on the upper surface of the track is obtained by a measuring mechanism, and the lifting height of the lifting rod is automatically adjusted by an adjusting mechanism, thereby realizing automatic adjustment of the track level. This improves the efficiency and accuracy of track level adjustment, reduces downtime, and increases production efficiency. Attached Figure Description

[0018] To better understand the above technical solutions, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, will illustrate the technical solutions. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0019] like Figure 1-4 The illustrated automatic leveling device for a chip placement machine track includes a track 1, a base plate 2, a measuring mechanism (not shown), and an adjusting mechanism 3. The track 1 is mounted on the upper side of the base plate 2, and the adjusting mechanism 3 is mounted on the lower side of the base plate 2. For ease of understanding, both the track 1 and the base plate 2 are shown as cut-off ends; the actual track and base plate are an array of multiple track 1s and base plates 2 arranged along the length direction as shown in the illustration.
[0020] like Figure 1 , Figure 2As shown, two through-holes 11 are opened in the middle of the track 1. The through-holes 11 are countersunk holes, and the two through-holes 11 are symmetrically distributed on both sides of the centerline of the track 1.
[0021] like Figure 1 , Figure 3 As shown, two threaded holes 21, matching the positions of the connecting holes 11, are provided in the center of the base plate 2. Bolts 4 pass through the connecting holes 11 and are screwed into the threaded holes 21 to fix the rail 1 to the upper surface of the base plate 2. Four adjustment holes 22 are provided around the threaded holes 21. The adjustment holes 22 are located within the vertical projection of the rail 1 onto the base plate 2, and the four adjustment holes 22 are symmetrically distributed on both sides of the centerline of the rail 1. The measuring mechanism is a laser height gauge, which is installed above the rail 1 and used to measure the height difference of the upper surface of the rail 1.
[0022] like Figure 1 , Figure 4 As shown, the adjustment mechanism 3 is installed on the lower side of the base plate 2. The adjustment mechanism 3 is a fixed-axis motor, and the step size of the fixed-axis motor can be selected from 0.0015-0.04mm. The fixed-axis motor is fixed to the bottom of the base plate 2, and a lifting rod 5 is fixedly installed at the output end of the fixed-axis motor. The diameter of the lifting rod 5 is smaller than the diameter of the adjustment hole 22. The lifting rod 5 passes through the adjustment hole 22 and abuts against the lower end face of the track 1.
[0023] In use, the height of the center position of the upper end face of track 1 can be set as the reference height, and multiple detection points are set on the upper end face of the track, located at the adjustment holes. A laser height gauge is used to measure the reference height and the heights of the detection points, and the height difference between the heights of different detection points and the reference height is calculated. If the height difference at a detection point is positive, the lifting rod is lowered using a fixed-axis motor; if the height difference at a detection point is negative, the lifting rod is raised using a fixed-axis motor until the difference between the heights of all detection points and the reference height is equal.
[0024] The technical solutions provided in this application have at least the following technical effects or advantages:
[0025] The height difference at different positions on the upper surface of the track is obtained by a measuring mechanism, and the lifting height of the lifting rod is automatically adjusted by an adjusting mechanism, thereby realizing automatic adjustment of the track level. This improves the efficiency and accuracy of track level adjustment, reduces downtime, and increases production efficiency.
