Description

Technical Field

[0001] This utility model relates to the field of integrated circuit board processing technology, and in particular to a chip mounter anti-misalignment device for chip mounters. Background Technology

[0002] An integrated circuit board is a carrier for integrated circuits. It has printed circuits on its surface and multiple electronic components are fixed on it. The process of mounting electronic components is also called surface mount technology.

[0003] In the prior art, a chip mounting device for preventing misalignment in integrated circuit board processing, with publication number CN220493489U, uses two connecting plates to clamp the integrated circuit board while using limiting blocks to fix it. Since two limiting blocks are fixed on one connecting plate, the distance between the two limiting blocks is limited, and the two limiting blocks cannot move. Since integrated circuit boards are generally square, the above-mentioned double-sided clamping method is mostly used to clamp both sides of the integrated circuit board. However, since the square structure of integrated circuit boards varies in size, the method of clamping the integrated circuit board with connecting plates and limiting blocks is relatively inflexible. Utility Model Content

[0025] Reference Figures 1-6 The anti-misalignment placement device for a pick-and-place machine includes a worktable 1, a pick-and-place machine body 2 fixedly mounted on the surface of the worktable 1, a fixed plate 3 above the worktable 1, a first motor 4 fixedly mounted on the surface of the worktable 1, a first threaded rod 5 mounted on the output end of the first motor 4, a first support plate 6 movably mounted at the end of the first threaded rod 5, the first support plate 6 being fixedly connected to the worktable 1, a first slider 7 threadedly connected to the outer side of the first threaded rod 5, the first slider 7 being fixedly connected to the fixed plate 3, a second slider 8 fixedly mounted at the bottom of the fixed plate 3, the second slider 8 having a guide rail 9 passing through it and being slidably connected to the guide rail 9, brackets 10 fixedly mounted at both ends of the guide rail 9, the brackets 10 being fixedly connected to the worktable 1. The fixed plate 3 is moved to the bottom of the pick-and-place machine body 2 by the first motor 4 and the first threaded rod 5, completing the first placement operation. Then the first motor 4 reverses, the fixed plate 3 returns to its original position, the circuit board is removed, and the circuit board to be placed is placed in for the second placement operation, which helps improve the working efficiency of the device.

[0026] A placement slot 11 is provided in the middle of the fixed plate 3. A second motor 12 is fixed to the inner wall of the fixed plate 3. An output shaft 13 is installed at the output end of the second motor 12. The output shaft 13 is movably connected to the fixed plate 3. A first bevel gear 14 is coaxially fixed to the output shaft 13. Four second bevel gears 15 are equally angled meshed with the first bevel gear 14. Each of the four second bevel gears 15 is coaxially connected to a second threaded rod 16. The second threaded rod 16 is movably connected to the fixed plate 3. A second support plate 17 is movably installed on the outer side of the second threaded rod 16. The second support plate 17 is fixedly connected to the fixed plate 3. The threaded rod 16 is threadedly connected to a movable plate 18, which passes through the fixed plate 3 and is slidably connected to the fixed plate 3. A clamping plate 19 is fixed to the end of the movable plate 18, and a guide rod 20 passes through the movable plate 18 and is slidably connected to the guide rod 20. Both ends of the guide rod 20 are fixedly connected to the inner wall of the fixed plate 3. The first bevel gear 14 drives the four second bevel gears 15 to rotate, which ultimately causes the four clamping plates 19 to move simultaneously. This allows for clamping and fixing of the four sides of the circuit board, which is convenient and fast. It can also be applied to circuit boards of the same size and has few limitations.

[0027] A limiting plate 21 is fixed on the surface of the workbench 1, and the limiting plate 21 is higher than the first slider 7 and the second slider 8. By setting the limiting plate 21, the fixing plate 3 can be prevented from moving outside the designated position, so that the patching is more accurate.

[0028] In this invention, during the surface mount process, the circuit board is placed in the middle of the mounting slot 11 on the fixing plate 3. Then, the second motor 12 is turned on, and the second motor 12 drives the first bevel gear 14 to rotate via the output shaft 13. The first bevel gear 14 meshes with four second bevel gears 15 simultaneously. The second bevel gears 15 are coaxially fixed with a second threaded rod 16. A movable plate 18 is threadedly connected to the outer side of the second threaded rod 16. The movable plate 18 is fixedly connected to the clamping plate 19. Multiple clamping plates 19 move simultaneously to clamp and fix the circuit board. Then, the first motor 4 is turned on, and the first motor 4 drives the first threaded rod 5 to rotate. The first slider 7 is threadedly connected to the outer side of the first threaded rod 5. The first slider 7 is connected to the fixing plate 3. The fixed plate 3 is fixedly connected, and with the assistance of the guide rail 9, the fixed plate 3 begins to slide. When the fixed plate 3 moves to the bottom of the pick-and-place machine body 2 and contacts the limit plate 21, the first motor 4 is turned off. The pick-and-place machine body 2 adopts the glue dispensing component in the anti-misalignment pick-and-place device for integrated circuit board processing, which is disclosed in CN220493489U. The glue in the glue storage tank of the glue dispensing component is connected to the plastic telescopic tube and the glue dispensing head through the delivery pipe. The glue is sprayed onto the integrated circuit board to place the circuit board. After the placement is completed, the first motor 4 is reversed and the fixed plate 3 returns to its original position. Then the second motor 12 is reversed, and the circuit board is released from the fixing action of the clamping plate 19 and the circuit board is taken out.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
