Description

Technical Field

[0001] This utility model relates to the field of electronic component assembly, and in particular to a chip auxiliary positioning structure. Background Technology

[0002] In the field of industrial automation production and inspection, line scan industrial cameras are one of the important industrial inspection equipment. Line scan industrial cameras achieve high-precision and high-speed imaging by scanning line by line with a linear array sensor. They can quickly and accurately acquire image information of the object surface, providing reliable data support for subsequent quality inspection, dimensional measurement, defect identification and other work.

[0003] The printed circuit board assembly (hereinafter referred to as "PCBA board") inside the line scan industrial camera integrates various key electronic components. Among them, the chip is the core of the PCBA board. The precise installation and positioning of the chip directly affects whether the line scan industrial camera can accurately acquire high-quality images.

[0004] Currently, in the production process of PCBA boards, chip installation mainly relies on manual wafer mounting. Due to the uncertainty of manual operation, deviations in the relative positions between chips are prone to occur during chip installation. These relative positional deviations directly affect the relative positional relationship between the chip's photosensitive area and other related components, causing the chip's photosensitive area to deviate from the design value and fail to integrate with other components, affecting the quality of image acquisition. Abnormal imaging by line scan industrial cameras further impacts production efficiency and product quality.

[0005] Therefore, a new technical solution is needed to address the problems existing in the current technology. Utility Model Content

[0020] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-8 As shown, a chip-assisted positioning structure includes a stage base 1, a chip mounting plate holder 2, a positioning ruler body 5, and a positioning ruler holder 4. The stage base 1 is equipped with an X-axis micro-adjustment component 11 and a Y-axis micro-adjustment component 12. The chip to be mounted needs to be installed at the corresponding position of the mounting area on the chip mounting plate body 3. By adjusting the X-axis micro-adjustment component 11 and the Y-axis micro-adjustment component 12, the positioning ruler holder 4 is moved in the X-axis and Y-axis directions, allowing for micro-adjustment of the positioning ruler holder 4 in both directions. The positioning ruler body 5 then aligns the chip to be mounted with the chip mounting plate. The corresponding positions on the main body 3 are precisely aligned and installed to adjust the relative positions of the positioning ruler body 5 and the chip mounting area. After reaching the predetermined position, the adjustment of the X-axis micro-adjustment component 11 and the Y-axis micro-adjustment component 12 is stopped. Since the micro-adjustment is a linear motion, the problem of relative tilt is avoided. The alignment deviation between the chip to be installed and the corresponding position of the chip mounting area on the chip mounting board body 3 is controlled within the design value range, thereby significantly improving the positional accuracy of chip installation, reducing the risk of chip functional failure or poor assembly due to misalignment, and effectively avoiding the problem of excessive error in traditional manual adjustment.

[0021] like Figures 2-5 As shown, the chip mounting plate body 3 is fixed on the chip mounting plate fixing base 2. In at least one embodiment, the upper surface of the chip mounting plate fixing base 2 is integrally formed with a plurality of positioning members 21 for fixing the chip mounting plate body 3. The positioning members 21 are positioned in correspondence with the positioning holes 32 opened on the chip mounting plate body 3. The positioning members 21 are cylindrical and located at the two side edges along the length direction of the upper surface of the chip mounting plate body 3. The positioning holes 32 are circular. The positioning members 21 pass through the positioning holes 32 to position the chip mounting plate body 3, thereby preventing the chip mounting plate body 3 from sliding. After positioning, the chip mounting plate body 3 and the chip mounting plate fixing seat 2 move as a whole. A baffle 22 is installed on the side of the chip mounting plate fixing seat 2 near the positioning ruler fixing seat 4. The baffle 22 plays an auxiliary limiting role for the chip mounting plate body 3. The positioning component 21 can also be other shapes such as columns, hooks or clips. The positioning hole 32 can also be elliptical, square, triangular or polygonal. The upper surface of the platform base 1 is provided with a receiving groove 13 for accommodating the chip mounting plate body 3. The length of the receiving groove 13 is greater than that of the chip mounting plate body 3. The chip mounting plate fixing seat 2 is placed in the receiving groove 13.

[0022] like Figures 6-10As shown, the positioning ruler fixing seat 4 is used to fix the positioning ruler body 5. The positioning ruler fixing seat 4 includes an upper plate 41 and a lower seat 42. The upper surface of the platform base 1 is provided with a mounting platform 14 for placing the positioning ruler fixing seat 4. The height of the upper surface of the mounting platform 14 is lower than the height of the upper surface of the platform base 1. The upper plate 41 is placed on the mounting platform 14. The length of the lower seat 42 is less than the length of the receiving groove 13. The lower seat 42 passes into the receiving groove 13. The positioning ruler fixing seat 4 and the chip mounting plate fixing seat 2 together clamp the chip mounting plate body 3. The upper end face of the mounting platform 14 and the platform base 1 form a stepped structure, which plays a lateral limiting role for the positioning ruler fixing seat 4, preventing the positioning ruler fixing seat 4 from moving outward of the platform base 1 during adjustment, and ensuring the relative position stability of the positioning ruler body 5 and the chip mounting plate body 3. A ruler groove 43 is opened between the upper plate 41 and the lower seat 42. The positioning ruler body 5 is partially embedded in the ruler groove 43. The positioning ruler body 5 is placed on the chip mounting plate body 3. On the mounting plate body 3, the positioning ruler body 5 is provided with a chip positioning structure, which includes several chip positioning slots 51. Chips are installed at the positions corresponding to the chip positioning slots 51 to ensure the relative position of the chips. At least one L-shaped right-angle notch 511 is opened at the inner corner of one side of the chip positioning slot 51. The chip can be attached along the L-shaped right-angle notch 511 of the positioning ruler to ensure the attachment position and avoid tilting. The positioning accuracy of the positioning ruler ensures the relative position accuracy between multiple chips and the relative position accuracy between the chip and the chip mounting plate body 3. In at least one embodiment, the cross-sectional shape of the lower seat 42 is U-shaped, with the U-shaped opening facing the chip mounting plate body 3. The distance between the inner sidewalls of the two ends of the lower seat 42 is greater than or equal to the length of the chip mounting plate body 3. When adjusting the position of the chip mounting plate body 3, the X-axis micro-adjustment member 11 abuts against the two ends of the lower seat 42. An L-shaped right-angle notch 511 is opened at the inner corner of one side of the chip positioning slot 51.

[0023] like Figure 1 and Figure 10As shown, a magnetic element 16 is provided on one side wall of the stage base 1 in the X-axis direction, and a mating element 31 is provided on the chip mounting plate holder 2 to magnetically engage with the magnetic element 16. Several through holes 15 are provided on both side walls in the length direction and one side wall in the width direction of the stage base 1. One end of the X-axis micro-adjustment element 11 and the Y-axis micro-adjustment element 12 passes through the through holes 15. In at least one embodiment, when the Y-axis micro-adjustment element 12 faces the user, the magnetic element 16 and the mating element 31 are located at the upper right corner of the stage base 1 and the chip mounting plate holder 2, with the chip mounting plate holder 2 pre-positioned on the right side to avoid gaps. A through hole 15 is provided on both side walls in the length direction of the stage base 1, and a through hole 15 is provided on one side wall in the width direction. The chip mounting plate body 3 is adjusted by inserting a Y-axis micro-adjustment component 12 through the middle through-hole 15. The appropriate through-hole 15 can be selected according to the specific size of the chip mounting plate body 3 and the adjustment requirements, thus expanding the compatibility range of chip mounting plates of different specifications. Through the magnetic attraction of the magnetic component 16 and the mating component 31, the chip mounting plate fixing seat 2 and the stage base 1 can be quickly pre-positioned, avoiding the idle stroke of micro-adjustment, reducing the fixing operation steps before adjustment, and improving assembly efficiency. The moderate magnetic attraction force can keep the chip mounting plate fixing seat 2 relatively stable before adjustment, and can be easily separated when adjustment or disassembly is required, which has operational flexibility.

[0024] Operating steps: S1. Insert the positioning member 21 into the positioning hole 32 of the chip mounting plate body 3, so that the chip mounting plate body 3 is fixed on the chip mounting plate fixing seat 2. S2. Place the mounting plate holder containing the chip mounting plate body 3 into the receiving groove 13, and pre-position it by magnetic attraction between the magnetic component 16 and the mating component 31. S3. Insert the positioning ruler body 5 into the ruler groove 43, and install the positioning ruler fixing seat 4 with the positioning ruler body 5 on the platform base 1. S4. Adjust the X-axis micro-adjustment component 11 and the Y-axis micro-adjustment component 12 to make the chip positioning slot 51 correspond to the position of the chip mounting area, place the chip in the position of the chip positioning slot 51, and install the chip into the corresponding position of the mounting area on the chip mounting board body 3. S5. After the chip is installed, remove the X-axis micro-adjustment 11 and the Y-axis micro-adjustment 12 in sequence, remove the positioning ruler fixing seat 4 away from the chip, and then remove the chip mounting board body 3 with the chip already mounted from the chip mounting board fixing seat 2.
