[0002] With the development of my country's semiconductor integrated circuit industry, all process steps of integrated circuits have been fully automated. Chips, also known as integrated circuits, are microelectronic circuits that integrate a large number of tiny electronic components (such as transistors, resistors, capacitors, etc.) on a single semiconductor substrate. Chips are the core components of modern electronic devices and computing systems. Chip manufacturing is a highly complex and sophisticated process. Different electronic devices have different requirements for chip functions and performance. Therefore, the size of the chip will also vary due to these requirements. The size of each type of chip is different, and the corresponding loading system is also different.

[0003] Deficiencies in the prior art: After the chips are punched and formed, they need to be loaded onto trays. The distances between chips with different spacings punched out from the mold are different, so different distances need to be made for the loading trays, and the suction cups for sucking the chips also need to change accordingly. In this case, for one device to load multiple types of products, it is necessary to replace multiple types of trays, which greatly reduces the efficiency and production capacity of the equipment, and the production costs of chip manufacturers will also increase significantly.

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention is provided with a camshaft and a roller. When the camshaft rotates, the roller moves in the inner cavity of the cam groove. The cam groove is spirally arranged, and the cam grooves on both sides are in opposite directions, driving a plurality of variable pitch carriers to uniformly adjust the distance between the variable pitch carriers according to chips of different widths and different spacings. After the adjustment is completed, the chip is moved by the suction cup assembly, and the chip is transferred to the fixed carrier for loading, so that chips of different widths and different spacings can be loaded on the same set of carriers, which greatly reduces the time for equipment to replace fixtures, improves production efficiency, and reduces production costs.

[0017] 2. The present invention uses a variable pitch mechanism to change the angle of motor rotation and adjust the size of the variable pitch according to the requirements of chips with different widths and spacings. Customers can set multiple positions according to the different distances of different chip types, replacing the original step that requires engineers to replace fixtures. Without replacing the material tray and the suction cup for sucking the chips, chips of various different distances can be loaded into the same carrier tray, reducing manual participation and the risk of erroneous operations.

[0018] 3. The present invention has a structure of double linear guides and rollers. When the variable pitch carrier is driven by the roller to move in the inner cavity of the cam groove, the variable pitch carrier slides on the top of the linear guide through the slider at the bottom, thereby ensuring the uniformity of the variable pitch of the variable pitch carrier. At the same time, the connecting block slides on the surface of the guide rod through the guide groove, thereby ensuring the accuracy of the moving direction of the variable pitch carrier and ensuring the stability of the variable pitch carrier during the adjustment process, reducing the operating friction of the mechanism, and improving the sensitivity of the mechanism's operating resistance response.

DETAILED DESCRIPTION

[0027] The present invention provides a chip loading device with equal and variable distances, such as Figure 1 - Figure 7 As shown, it includes a support frame 1 and a fixing seat 2 fixedly installed on one side of the top end thereof, a camshaft 10 is rotatably connected to the middle part of the inner cavity of the support frame 1, cam grooves 11 are provided on both sides of the outer surface of the camshaft 10, a suction cup assembly 3 for sucking the chip is provided on the side of the fixing seat 2 away from the camshaft 10, and a pitch changing mechanism 4 for changing the pitch of the chip is provided on the top end of the fixing seat 2.

[0028] Further, such as Figure 3 As shown, the pitch changing mechanism 4 includes a plurality of pitch changing carriers 41 located at the top of the fixed seat 2. The pitch changing carriers 41 are supported and stabilized by the fixed seat 2. By moving at the top of the fixed seat 2, the uniformity and stability during the distance adjustment process can be increased. One end of the pitch changing carrier 41 close to the camshaft 10 is fixedly connected to a connecting block 43, and the bottom end of the connecting block 43 is fixedly connected to a roller 44.

[0029] Further, such as Figure 3 and Figure 4 As shown, both sides of the top of the fixed seat 2 are fixedly connected with linear guide rails 5, and both sides of the bottom of the variable pitch carrier 41 are fixedly connected with sliders 42. The position of the slider 42 corresponds to the position of the linear guide rail 5. The slider 42 is movably connected to the top of the linear guide rail 5. When the variable pitch carrier 41 moves, the slider 42 at the bottom drives the variable pitch carrier 41 to slide on the top of the linear guide rail 5, thereby ensuring the stability and uniformity of the variable pitch carrier 41 when changing the pitch.

[0030] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, both sides of the inner wall of the support frame 1 are fixedly connected to one end close to the fixed seat 2, and a guide rod 7 is fixedly connected between the two limit blocks 6. A guide groove 45 is opened on the side of the variable pitch carrier 41 close to the support frame 1, and the position of the guide groove 45 corresponds to the position of the guide rod 7. The guide rod 7 passes through and is movably connected to the inner cavity of the guide groove 45. When the variable pitch carrier 41 adjusts the distance, the connecting block 43 slides on the surface of the guide rod 7 through the guide groove 45, and the limit blocks 6 limit the moving range of the variable pitch carrier 41. The accuracy of the moving direction of the variable pitch carrier 41 is guaranteed by the guide rod 7. At the same time, through the coordinated use of the double linear guide rails 5 and the guide rod 7, the stability of the variable pitch carrier 41 during the adjustment process can be ensured, the running friction of the mechanism can be reduced, and the sensitivity of the mechanism's running resistance reaction can be improved.

[0031] Further, such as Figure 5As shown, the shape of the cam groove 11 is spirally arranged, and the directions between the two cam grooves 11 are opposite. The position of the roller 44 corresponds to the position of the cam groove 11, and the bottom end of the roller 44 is movably connected to the inner cavity of the cam groove 11. The roller 44 moves along the shape of the cam groove 11, driving the variable pitch carrier 41 to move evenly to both sides, so that a plurality of variable pitch carriers 41 can evenly adjust the distance between the variable pitch carriers 41 according to chips of different widths and different spacings, and move to a suitable position.

[0032] Further, such as Figure 1 As shown, a motor 8 is fixedly installed at one end of the support frame 1, and a coupling 9 is fixedly connected to the output end of the motor 8. The end of the camshaft 10 close to the motor 8 is fixedly connected to the coupling 9. The camshaft 10 is connected to the motor 8 through the coupling 9. The coupling 9 makes the rotation of the camshaft 10 more stable. The camshaft 10 is driven to rotate by the motor 8. According to the requirements of chips with different widths and spacings, the rotation angle of the motor 8 is changed, and the size of the variable pitch is adjusted. The customer can set multiple positions according to the different distances of different chip types, replacing the original step that requires engineers to replace the fixture. Without replacing the material tray and the suction cup for sucking the chip, it can realize the operation of loading chips with different distances into the same carrier tray, reducing manual participation and reducing the risk of erroneous operation.

[0033] Further, such as Figure 6 As shown, the suction cup assembly 3 includes an equipment frame 31 located above the fixed seat 2, and two driving guide rails 32 are provided at the bottom end of the equipment frame 31. The bottom end of the driving guide rail 32 is fixedly connected with a connecting frame 33, and the connecting frame 33 is driven to move up and down by the driving guide rail 32. A plurality of suction nozzles 34 are penetrated and fixedly connected to the lower part of the connecting frame 33, and a plurality of positioning frames 35 are fixedly installed at the bottom end of the connecting frame 33.

[0034] Further, such as Figure 6 As shown, a plurality of suction nozzles 34 and positioning frames 35 are arranged in a rectangular array, and the lower part of the suction nozzle 34 is located in the middle of the inner cavity of the positioning frame 35. The position of the chip is first determined by the positioning frame 35, so that the suction nozzle 34 can suck the chip tray 12 more accurately.

[0035] Further, such as Figure 7As shown, a chip tray 12 is arranged below the suction cup assembly 3, and a plurality of chips are arranged at equal distances on the top of the chip tray 12. Since the chips are punched out from a mold, the punched chips need to be stored in the chip tray 12. A groove is provided at the top of the chip tray 12, and the position of the suction nozzle 34 corresponds to the position of the groove. The top of the chip tray 12 is parallel to the top of the camshaft 10. The chip tray 12 storing the chips is placed below the suction cup assembly 3, and the suction nozzle 34 is adsorbed on the top surface of the chips in the chip tray 12. The chips in the chip tray 12 are placed in the variable distance mechanism 4 through the suction cup assembly 3.

[0036] Further, such as Figure 1 and Figure 7 As shown, a fixed carrier 13 is provided on the side of the support frame 1 away from the suction cup assembly 3, and a storage groove is provided on the top of the fixed carrier 13 of the variable pitch carrier 41. The position and shape of the positioning frame 35 are adapted to the position and shape of the storage groove, so that the chip is more stable when stored. When the chip is placed in the variable pitch carrier 41 and the distance is adjusted, the suction cup assembly 3 sucks the chip on the variable pitch carrier 41 and places it in the fixed carrier 13 for loading, so that chips of different widths and different spacings can be loaded on the same set of carriers, which greatly reduces the time for equipment to replace fixtures, improves production efficiency, and reduces production costs.

[0037] The working principle of the present invention is as follows: first, a suction cup assembly 3 is set on one side of the fixed seat 2, and the punched chip is placed in the chip material tray 12, and then the chip material tray 12 is placed under the suction cup assembly 3, and a fixed carrier 13 is set on the side of the fixed seat 2 away from the suction cup assembly 3, and the top of the chip material tray 12 is parallel to the top of the camshaft 10, and then the suction cup assembly 3 is started, and the connecting frame 33 is driven to move up and down by the driving guide rail 32, so that the suction nozzle 34 is adsorbed on the top of the chip in the chip material tray 12, and it is placed in the storage groove at the top of the variable pitch carrier 41, and then the motor 8 is started, and the motor 8 causes the coupling 9 to rotate, driving the camshaft 10 to rotate. According to the requirements of chips of different widths and different spacings, the rotation angle of the motor 8 is changed to adjust the size of the variable pitch. Since the shape of the cam groove 11 is spirally arranged, and the directions between the two cam grooves 11 are opposite, when the camshaft 10 rotates, the roller 44 moves along the inner cavity of the cam groove 11 as the camshaft 10 rotates, driving the variable pitch carrier 41 to move evenly to both sides. The motor 8 is moved so that several variable pitch carriers 41 can evenly adjust the distance between the variable pitch carriers 41 according to chips of different widths and different spacings. The motor 8 is stopped after adjusting to the appropriate position. When the variable pitch carrier 41 adjusts the distance, the slider 42 at the bottom drives the variable pitch carrier 41 to slide on the top of the linear guide 5 to ensure the stability and uniformity of the variable pitch carrier 41 when changing the pitch. The connecting block 43 slides on the surface of the guide rod 7 through the guide groove 45, and the guide rod 7 ensures the accuracy of the moving direction of the variable pitch carrier 41. At the same time, the coordinated use of the double linear guide 5 and the guide rod 7 can ensure the stability of the variable pitch carrier 41 during adjustment, reduce the running friction of the mechanism, and improve the sensitivity of the mechanism's running resistance reaction. After the adjustment is completed, the chip on the variable pitch carrier 41 is sucked by the suction cup assembly 3 and placed on the fixed carrier 13 for loading, so that chips of different widths and different spacings can be loaded on the same set of carriers, which greatly reduces the time for equipment to replace fixtures, improves production efficiency, and reduces production costs.
