Description

Technical Field

[0001] This utility model relates to the field of chip manufacturing technology, and in particular to a chip vacuum adsorption loading device that facilitates chip alignment. Background Technology

[0002] In the chip manufacturing process, the chip needs to be precisely loaded onto a carrier or processing station for subsequent packaging, testing and other processes.

[0003] Currently, chip loading mostly uses vacuum adsorption devices for gripping and moving. However, due to the small size of chips and the high precision requirements, existing devices have the following problems in the alignment process: relying solely on manual visual inspection or simple mechanical positioning makes it difficult to ensure accurate alignment between the chip and the loading station, which can easily lead to chip damage or errors in subsequent processes; multiple manual adjustments to the chip position are required, which is time-consuming and labor-intensive, affecting production efficiency; and it is inconvenient to disassemble and replace the suction cup according to the size of the chip, reducing its effectiveness. Therefore, a chip vacuum adsorption loading device that facilitates alignment is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a convenient chip vacuum adsorption loading device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a preferred embodiment of this utility model, the adjustment and alignment mechanism includes an upper motor fixedly connected to one side of the upper slide rail, an upper lead screw fixedly connected to the output shaft of the upper motor, an upper slider threaded on the outer side of the upper lead screw, a lower slide rail fixedly connected to the bottom of the upper slider, a lower motor fixedly connected to the front side of the lower slide rail, a lower lead screw fixedly connected to the output shaft of the lower motor, and a lower slider threaded on the outer side of the lower lead screw.

[0008] In a preferred embodiment of this invention, the upper slider is slidably sleeved within the upper slide rail, and the lower slider is slidably sleeved within the lower slide rail.

[0009] In a preferred embodiment of this invention, a second cylinder is fixedly connected to one side of the lower slider, a rack is fixedly connected to the output shaft of the second cylinder, a rotating shaft is rotatably connected to the bottom of the lower slider, a gear is fixedly connected to the top of the rotating shaft, the gear meshes with the rack, and the connecting disc is fixedly connected to the bottom end of the rotating shaft.

[0010] As a preferred embodiment of this utility model, the vacuum adsorption mechanism includes a vacuum generator fixedly connected to the bottom of the connecting plate, a suction pipe fixedly connected to the bottom of the vacuum generator, a suction cup detachably fixedly connected to the bottom end of the suction pipe, a connection port fixedly connected to the top of the suction cup, and a convenient connection sealing component provided between the connection port and the suction pipe.

[0011] As a preferred embodiment of this utility model, the convenient connection sealing assembly includes a lower ring fixedly sleeved on the outside of the connection port and an upper ring fixedly sleeved on the outside of the suction pipe. Four compression blocks are fixedly connected to the bottom of the upper ring. An annular groove is formed on the inner wall of the lower ring. A sealing ring is movably sleeved in the annular groove. An air bladder is fixedly sleeved on the outside of the sealing ring. Four pressure blocks are fixedly connected to the outside of the air bladder. The compression blocks movably abut against the outside of the pressure blocks.

[0012] In a preferred embodiment of this utility model, a convex ring is fixedly sleeved on the outer side of the lower ring, an elastic part is fixedly connected to the bottom of the upper ring, a retaining ring is fixedly connected to the bottom of the elastic part, the retaining ring is movably engaged with the bottom of the convex ring, an external thread is provided on the outer side of the upper ring, a nut is sleeved on the outer thread of the external thread, and the nut is movably abutted against the outer side of the elastic part.

[0013] In a preferred embodiment of this invention, the sealing ring is movably abutted against the connection between the connection port and the air extraction pipe.

[0014] In this invention, a convenient chip vacuum adsorption loading device is described. The chip to be loaded is adsorbed by a suction cup in the vacuum adsorption mechanism using negative pressure. Two industrial cameras capture images of the chip, which are compared with a standard image at the loading station to calculate the chip's positional and angular deviations in the X and Y axes. Based on the deviation data, the PLC controller controls the operation of the upper motor, lower motor, and cylinder two.

[0015] In this utility model, a convenient chip vacuum adsorption loading device is described. When it is necessary to use the vacuum adsorption of chips of different sizes, the suction cup and the lower ring are pressed upward, so that the extrusion block is inserted into the annular groove to press the pressure block. The four pressure blocks press the air bag inward, so that the air bag expands inward and presses the sealing ring, thus firmly pressing the sealing ring at the connection between the connection port and the air extraction pipe, improving the sealing performance of the connection. At the same time, the elastic part and the retaining ring move outward until the retaining ring is no longer pressed by the convex ring. At this time, under the elasticity of the elastic part, the retaining ring is engaged with the outside of the convex ring, achieving the purpose of engagement and fixation. In order to ensure the firmness of the connection, the nut is unscrewed, so that the nut moves down and abuts against the outside of the elastic part, preventing the elastic part from deforming outward and affecting the firmness of the engagement.

[0016] This utility model has a reasonable structural design. By combining X-axis and Y-axis translation adjustment and rotation angle adjustment, along with real-time monitoring and feedback from an industrial camera, it can achieve precise alignment, meet the requirements of high-precision chip loading, and facilitate the disassembly and replacement of the suction cup according to the size of the chip, thus improving the versatility of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A convenient chip vacuum adsorption loading device includes a base 1, a loading station 2 for chip loading fixedly connected to the top of the base 1, a gantry 3 fixedly connected to the top of the base 1, industrial cameras 7 fixedly connected to the inner walls on both sides of the gantry 3, a PLC controller 4 fixedly connected to one side of the gantry 3, a cylinder 5 fixedly connected to the top of the gantry 3, an upper slide rail 801 fixedly connected to the output shaft of the cylinder 5, a connecting plate 813 provided at the bottom of the upper slide rail 801, an adjustment and alignment mechanism 8 provided between the upper slide rail 801 and the connecting plate 813, a vacuum adsorption mechanism 9 provided at the bottom of the connecting plate 813, and two guide rods 6 fixedly connected to the top of the upper slide rail 801, both guide rods 6 being slidably connected to the top of the gantry 3.

[0024] Furthermore, refer to Figure 1 and Figure 2The adjusting alignment mechanism 8 includes an upper motor 803 fixedly connected to one side of the upper slide rail 801. An upper lead screw 804 is fixedly connected to the output shaft of the upper motor 803. An upper slider 802 is threaded on the outer side of the upper lead screw 804. A lower slide rail 805 is fixedly connected to the bottom of the upper slider 802. A lower motor 808 is fixedly connected to the front side of the lower slide rail 805. A lower lead screw 809 is fixedly connected to the output shaft of the lower motor 808. A lower slider 806 is threaded on the outer side of the lower lead screw 809.

A connecting disc 813 is fixedly connected to the bottom end of the rotating shaft 812.

[0025] The above scheme is adopted as follows: the suction cup 902 in the vacuum adsorption mechanism adsorbs the chip to be loaded through negative pressure. Two industrial cameras 7 capture images of the chip and compare them with the standard images of the loading station 2 to calculate the positional and angular deviations of the chip in the X and Y axes. Based on the deviation data, the PLC controller 4 controls the operation of the upper motor 803, the lower motor 808, and the cylinder 807. The upper motor 803 drives the upper slider 802 to move and adjust along the X axis, and the lower motor 808 drives the lower slider 806 to move and adjust along the Y axis. The cylinder 807 drives the rack 811 to move laterally. The rack 811 drives the gear 810, the rotating shaft 812, the suction cup 902, and the chip to rotate and adjust, so that the chip is aligned with the loading station. After alignment, the cylinder 5 drives the suction cup 902 to move downward to place the chip on the loading station 2. The vacuum generator 901 is turned off to release the negative pressure and place the chip on the loading station, completing the loading process.

[0026] Furthermore, the upper slider 802 is slidably sleeved within the upper slide rail 801, and the lower slider 806 is slidably sleeved within the lower slide rail 805, which facilitates the guidance of the upper and lower sliders and makes their movement more stable.

[0027] Furthermore, the vacuum adsorption mechanism 9 includes a vacuum generator 901 fixedly connected to the bottom of the connecting plate 813. The bottom of the vacuum generator 901 is fixedly connected to an air extraction pipe 903. The bottom end of the air extraction pipe 903 is detachably fixedly connected to a suction cup 902. The top of the suction cup 902 is fixedly connected to a connection port 904. A convenient connection sealing component is provided between the connection port 904 and the air extraction pipe 903. Through the vacuum generator 901, the air in the suction cup 902 can be extracted to form a negative pressure. Under the negative pressure, the chip can be adsorbed and fixed.

[0028] Furthermore, refer to Figures 1-4The convenient connection sealing assembly includes a lower ring 906 fixedly sleeved on the outside of the connection port 904 and an upper ring 905 fixedly sleeved on the outside of the suction pipe 903. Four compression blocks 909 are fixedly connected to the bottom of the upper ring 905. An annular groove 915 is formed on the inner wall of the lower ring 906. A sealing ring 907 is movably sleeved in the annular groove 915. An air bladder 908 is fixedly sleeved on the outside of the sealing ring 907. Four pressure blocks 916 are fixedly connected to the outside of the air bladder 908. The compression blocks 909 movably abut against the pressure blocks 916. On the outside, the sealing ring 907 is movably abutted against the connection between the connection port 904 and the suction pipe 903. The outer side of the lower ring 906 is fixedly fitted with a protruding ring 913. The bottom of the upper ring 905 is fixedly connected with an elastic part 912. The bottom of the elastic part 912 is fixedly connected with a retaining ring 914. The retaining ring 914 is movably engaged with the bottom of the protruding ring 913. The outer side of the upper ring 905 is provided with an external thread 910. The outer thread of the external thread 910 is fitted with a nut 911. The nut 911 is movably abutted against the outer side of the elastic part 912.

[0029] Using the above scheme: When vacuum adsorption is required for chips of different sizes, the suction cup 902 and the lower ring 906 are pressed upwards, causing the pressing block 909 to be inserted into the annular groove 915 to press the pressure block 916. The four pressure blocks 916 press the airbag 908 inwards, causing the airbag 908 to expand inwards and press the sealing ring 907. This firmly presses the sealing ring 907 onto the connection between the connection port 904 and the suction pipe 903, improving the sealing performance of the connection. At the same time, the elastic part 912 and the retaining ring 914 move outwards until the retaining ring 914 is no longer pressed by the convex ring 913. At this time, under the elasticity of the elastic part 912, the retaining ring 914 is engaged with the outside of the convex ring 913, achieving the purpose of engagement and fixation. To ensure the firmness of the connection, the nut 911 is unscrewed, causing the nut 911 to move downwards and abut against the outside of the elastic part 912, preventing the elastic part 912 from deforming outwards and affecting the firmness of the engagement.

[0030] In this invention, during use, the suction cup 902 in the vacuum adsorption mechanism adsorbs the chip to be loaded through negative pressure. Two industrial cameras 7 capture images of the chip and compare them with the standard images at the loading station 2 to calculate the positional and angular deviations of the chip in the X and Y axes.

[0031] Based on the deviation data, the PLC controller 4 controls the operation of the upper motor 803, the lower motor 808, and the second cylinder 807. The upper motor 803 drives the upper slider 802 to move along the X-axis, and the lower motor 808 drives the lower slider 806 to move along the Y-axis. The second cylinder 807 drives the rack 811 to move laterally, and the rack 811 drives the gear 810, the rotating shaft 812, the suction cup 902, and the chip to rotate, so that the chip is aligned with the loading station. After alignment, the first cylinder 5 drives the suction cup 902 to move down and place the chip on the loading station 2. The vacuum generator 901 is turned off to release the negative pressure and place the chip on the loading station, completing the loading process.

[0032] When vacuum adsorption is required for chips of different sizes, the suction cup 902 and the lower ring 906 are pressed upwards, causing the pressing block 909 to insert into the annular groove 915 and press the pressure block 916. The four pressure blocks 916 press the airbag 908 inwards, causing the airbag 908 to expand inwards and press the sealing ring 907. This firmly presses the sealing ring 907 onto the connection between the connection port 904 and the suction pipe 903, improving the sealing performance of the connection. At the same time, the elastic part 912 and the retaining ring 914 move outwards until the retaining ring 914 is no longer pressed by the convex ring 913. At this point, under the elasticity of the elastic part 912, the retaining ring 914 is engaged with the outside of the convex ring 913, achieving the purpose of engagement and fixation. To ensure the firmness of the connection, the nut 911 is unscrewed, causing the nut 911 to move downwards and abut against the outside of the elastic part 912, preventing the elastic part 912 from deforming outwards and affecting the firmness of the engagement.
