Description

Technical Field

[0001] This invention relates to the field of chip manufacturing equipment, and more particularly to a chip variable-pitch conveying device. Background Technology

[0002] In the chip manufacturing process, rectangular trays are often used to hold the chips. The trays have several hollowed-out grooves, and each groove can hold one chip.

[0003] In subsequent chip testing, the chips need to be removed from the tray and loaded into the testing equipment for testing. In order to test multiple chips simultaneously, the gripping device can be equipped with multiple gripping parts, which can pick up the chips to be tested from multiple slots in the tray and transport them to the testing equipment for chip testing.

[0004] However, the test spacing of the testing device is different from the spacing between the grooves in the tray, which means that the testing device cannot test multiple chips at the same time, resulting in low testing efficiency and hindering chip production.

[0005] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a chip variable-pitch transmission device.

[0007] This invention can be achieved through the following technical solutions: This invention discloses a chip variable-pitch conveying device, comprising a base plate, a positioning lead screw and a sliding rod disposed on the top of the base plate, the positioning lead screw being driven to rotate by a positioning motor, a slide table disposed on the top of the base plate, a threaded tube and a sliding tube fixed at the bottom of the slide table, the positioning lead screw passing through the threaded tube and threadedly connected to the threaded tube, the sliding rod passing through the sliding tube and slidably connected to the sliding tube, a support platform disposed on the top of the slide table, support shafts symmetrically fixed on both sides of the support platform, the support shafts passing through the support platform at corresponding positions and rotatably connected to the support platform, one of the support shafts being fixed to the output end of a rotary motor, a positioning rod disposed on the support platform, a positioning tube evenly disposed on the positioning rod and rotatably connected to the positioning rod, a fixing seat disposed on each positioning tube, a positioning gear disposed on the fixing tube, and a rotating shaft disposed on the support platform below the positioning rod, the rotating shaft being driven to rotate by a support motor, a limit gear being fixed on the rotating shaft at a position corresponding to the positioning gear, the limit gear meshing with the positioning gear at the corresponding position. Four adjacent positioning tubes form a group, and the size of the positioning gears in each group gradually increases from left to right. When the rotating shaft rotates, the smaller positioning gears rotate at a larger angle, allowing the rotation angle of each positioning tube in each group to gradually decrease from left to right. This ensures that the fixed seats are staggered. The robotic arm picks up each chip from the tray and places it on the respective fixed seat. The rotating shaft is driven by a support motor. Because the positioning gears on adjacent positioning tubes are of different sizes, the rotation angles of adjacent positioning tubes are different when the rotating shaft rotates, allowing adjacent fixed seats to be staggered. This ensures that the line connecting every four fixed seats is parallel to the axis of the positioning rod. The positioning motor drives the positioning screw to rotate. When the positioning screw rotates, the slide moves. When the slide moves to below the testing device, chips with the same rotation angle are grouped together. The testing device tests the group of chips directly below the testing device. After one group of chips is tested, the testing device rises, and the rotary motor drives the support shaft to rotate a certain angle, so that another group of chips can be placed directly below the testing device. The other group of chips is then tested again, and the process is repeated. After all chips have been tested, the support motor drives the rotary shaft to rotate in the opposite direction, and all the fixed seats return to their initial positions. This device can offset adjacent fixed seats, allowing the distance between adjacent test chips to be adjusted during testing, so that the spacing between the chips on the tray is adjusted to meet the testing spacing of the testing device.

[0008] Preferably, each of the mounting bases is provided with a mounting slot, and the mounting base is also provided with multiple air holes connected to a vacuum device. After the chip is placed in each mounting slot, the vacuum device evacuates the air hole positions, thereby fixing the chip in each mounting slot.

[0009] Preferably, a main gear is fixed at the output end of the supporting motor, and a driven gear is fixed on the rotating shaft at a position corresponding to the main gear, the driven gear meshing with the main gear.

[0010] Preferably, a limit screw and a support rod are also provided above the base plate. The limit screw is driven to rotate by a limit motor. A slide plate is also provided above the base plate. The limit screw passes through the slide plate and is threadedly connected to the slide plate. The support rod passes through the slide plate and is slidably connected to the slide plate. Multiple cylinders are also fixed on the slide plate. A fixing plate is provided below the slide plate. The piston rod ends of the cylinders are all fixed to the fixing plate. The testing device is fixed on the fixing plate. After one set of chips is tested, the limit screw is driven to rotate by the limit motor. When the limit screw rotates, the slide plate moves a certain distance, and the testing device reaches directly above another set of chips for testing.

[0011] Compared with existing technologies, the present invention has the following advantages: This device can stagger adjacent mounting bases, allowing for adjustment of the distance between adjacent test chips during testing, thus adjusting the chip spacing on the tray to meet the testing spacing requirements of the testing device.

[0013] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings: Example

[0014] like Figure 1 and Figure 2As shown, this utility model provides a chip variable-pitch conveying device, including a base plate 1. A positioning screw 2 and a slide rod 3 are arranged on the top of the base plate 1. The positioning screw 2 is driven to rotate by a positioning motor 4. A slide table 5 is also arranged on the top of the base plate 1. A threaded tube 6 and a sliding tube 7 are fixed at the bottom of the slide table 5. The positioning screw 2 passes through the threaded tube 6 and is threadedly connected to the threaded tube 6. The slide rod 3 passes through the sliding tube 7 and is slidably connected to the sliding tube 7. A support platform 8 is arranged on the top of the slide table 5. Support shafts 9 are symmetrically fixed on both sides of the support platform 8. The support shafts 9 pass through the support platform 8 at corresponding positions and are rotatably connected to the support platform 8. Connecting the support shaft 9, one of the support shafts 9 is fixed to the output end of the rotary motor 10. A positioning rod 11 is also fixed on the support platform 8. Positioning tubes 12 that are rotatably connected to the positioning rod 11 are evenly arranged on the positioning rod 11. A fixing seat 13 is fixed on each positioning tube 12. A positioning gear 16 is also fixed on the fixing tube. A rotating shaft 17 is also provided on the support platform 8 below the positioning rod 11. The rotating shaft 17 is driven to rotate by the support motor 21. A limit gear 18 is fixed on the rotating shaft 17 at a position corresponding to the positioning gear 16. The limit gear 18 meshes with the positioning gear 16 at the corresponding position. Four adjacent positioning tubes 12 form a group. The size of the positioning gears 16 in each group gradually increases from left to right. When the rotating shaft 17 rotates, the smaller positioning gears 16 rotate at a larger angle, allowing the rotation angle of each positioning tube 12 in each group to gradually decrease from left to right. This ensures that the fixed seats 13 are staggered. The robotic arm picks up each chip from the tray and places it on the fixed seat 13. The rotating shaft 17 is driven to rotate by the support motor 21. Because the positioning gears 16 on adjacent positioning tubes 12 are of different sizes, the rotation angles of adjacent positioning tubes 12 are different when the rotating shaft 17 rotates, allowing adjacent fixed seats 13 to be staggered. This ensures that the line connecting every four fixed seats 13 is parallel to the axis of the positioning rod 11. The positioning motor 4 drives the rotation. When the positioning screw 2 rotates, the slide 5 moves and moves to the bottom of the testing device (not shown). Chips with the same rotation angle are grouped together. The testing device tests the group of chips directly below the testing device. After the testing of a group of chips is completed, the testing device rises, and the rotary motor 10 drives the support shaft 9 to rotate at a certain angle, so that another group of chips can reach the bottom of the testing device. The other group of chips is tested again, and the cycle continues. After all chips have been tested, the support motor 21 drives the rotary shaft 17 to rotate in the opposite direction, and each fixed seat 13 returns to its initial position. This device can offset adjacent fixed seats 13, so that the distance between adjacent test chips can be adjusted during testing, so that the spacing of the chips on the tray can be adjusted to meet the testing spacing of the testing device.

[0015] Each mounting base 13 is provided with a mounting groove 14, and the mounting base 13 is also provided with multiple air holes 15 connected to a vacuum device. After the chip is placed in each mounting groove 14, the vacuum device draws a vacuum at the positions of the air holes 15, which can fix the chip in each mounting groove 14.

[0016] Among them, a main gear 20 is fixed at the output end of the support motor 21, and a driven gear 19 is fixed on the rotating shaft 17 at a corresponding position to the main gear 20. The driven gear 19 meshes with the main gear 20. Example

[0017] This utility model provides a chip variable-pitch conveying device. Based on the structure and principle of Embodiment 1, this embodiment further includes a limiting screw 22 and a support rod 23 above the base plate 1. The limiting screw 22 is driven to rotate by a limiting motor 25. A sliding plate 24 is also provided above the base plate 1. The limiting screw 22 passes through the sliding plate 24 and is threadedly connected to it. The support rod 23 passes through the sliding plate 24 and is slidably connected to it. Multiple cylinders 26 are fixed on the sliding plate 24. A fixing plate 27 is provided below the sliding plate 24, and the piston rod ends of the cylinders 26 are all fixed to the fixing plate 27. The testing device is fixed on the fixing plate 27. After one set of chips is tested, the limiting screw 22 is driven to rotate by the limiting motor 25. When the limiting screw 22 rotates, the sliding plate 24 moves a certain distance, and the testing device reaches directly above another set of chips for testing.
