Abstract
Description
Technical Field
[0001] This utility model relates to the field of chip testing technology, and in particular to a pressure testing mechanism. Background Technology
[0002] Currently, the common operating mode in the field of translational sorting machines is as follows: a single machine has two pressure testing arms and two material conveying tracks. The two pressure testing arms alternately lift and lower the material on the two conveying tracks, and alternately move to the test position to perform pressure testing, and then alternately release the material on the two conveying tracks.
[0003] However, the chips tested by the sorting machine sometimes require the addition of customized hardware to the pressure head, thereby increasing the total thickness of the pressure head in the original pressure testing equipment. When the total thickness of the pressure head exceeds the safety operation requirements, even if the pressure head rises to the top, it will still interfere with the conveyor track, preventing the pressure head from moving above the conveyor track. For existing technology, to enable the thicker pressure head with customized functions to operate normally on the equipment, modifications to the vertical stroke of the equipment are required, which is costly and time-consuming.
[0004] Therefore, there is an urgent need for a pressure testing mechanism to solve the aforementioned problems. Utility Model Content

[0043] like Figure 1 and Figure 2As shown, this embodiment provides a pressure testing mechanism, which includes a support 1, a conveying track 2, a tray assembly 3, a pressure testing assembly 4, a test seat 8, a first drive assembly (not shown) and a second drive assembly (not shown). Specifically, the conveying track 2 extends along a first direction; the conveying track 2 is used to convey the tray assembly 3; the pressure testing assembly 4 includes a first pressure rod 41, a pickup pressure head 42, a second pressure rod 43, a test pressure head 44 and a connecting plate 45. The pickup pressure head 42 is connected to the bottom of the first pressure rod 41 and is used to pick up the chip. The test pressure head 44 is connected to the bottom of the second pressure rod 43 and is used to pressure test the chip; the first pressure rod 41 and the second pressure rod 43 are located on both sides of the connecting plate 45 along the second direction, and the first pressure rod 41 and the second pressure rod 43 are connected to each other. Two pressure rods 43 are slidably connected to a connecting plate 45 in the vertical direction, and the connecting plate 45 is slidably connected to a bracket 1 in the second direction. The test seat 8 is located on one side of the conveying track 2 along the second direction. The first driving assembly is used to drive the connecting plate 45 to slide in the second direction, so that the pickup head 42 moves between the top of the test seat 8 and the top of the conveying track 2, and the test head 44 can follow the pickup head 42 and move to the top of the test seat 8. The second driving assembly is used to drive the first pressure rod 41 and the second pressure rod 43 to rise and fall respectively. In this embodiment, the first direction is X, the second direction is Y, and the first direction is perpendicular to the second direction.
[0044] During testing, the conveyor track 2 moves the tray assembly 3 carrying the chip to one side of the test stand 8. Then, the first drive assembly moves the pick-up head 42 above the conveyor track 2 via the drive connection plate 45. The second drive assembly drives the first pressure rod 41 to descend, and the pick-up head 42 picks up the chip. The second drive assembly then drives the first pressure rod 41 to rise. The first drive assembly moves the pick-up head 42 above the test stand 8 via the drive connection plate 45. The second drive assembly drives the first pressure rod 41 to descend, and the pick-up head 42 places the chip on the test stand 8. Then, the second drive assembly drives the first pressure rod 41 to rise. The first drive assembly moves the test head 44 above the test stand 8 via the drive connection plate 45. In one step, the second drive assembly drives the second pressure rod 43 to descend, causing the test pressure head 44 to press and test the chip. Then, the second drive assembly drives the second pressure rod 43 to rise. The first drive assembly, through the drive connection plate 45, moves the pickup pressure head 42 above the test base 8. The second drive assembly drives the first pressure rod 41 to descend, and the pickup pressure head 42 picks up the chip from the test base 8. The second drive assembly then drives the first pressure rod 41 to rise. The first drive assembly, through the drive connection plate 45, moves the pickup pressure head 42 above the conveyor track 2. The second drive assembly drives the first pressure rod 41 to descend, and the pickup pressure head 42 places the tested chip onto the material tray assembly 3. Finally, the second drive assembly drives the first pressure rod 41 to rise, completing the chip testing.
[0045] This embodiment involves a simple modification to the existing pressure testing equipment. The test pressure head 44 does not need to be moved above the conveyor track 2. Therefore, the thickness of the test pressure head 44 is not a concern. A thicker test pressure head 44 with customized functions can operate normally on the pressure testing mechanism, directly achieving the production objective, shortening the product testing changeover cycle, and reducing labor costs. Furthermore, in this embodiment, the first pressure rod 41 and the second pressure rod 43 are connected by a connecting plate 45. Therefore, only one first drive assembly is needed to move the first pressure rod 41 and the second pressure rod 43 along the second direction, reducing equipment production costs and simplifying the equipment structure.
[0046] In this embodiment, the thickness of the pickup head 42 is less than the thickness of the test head 44. The pickup head 42 can adsorb the chip, and the test head 44 has customized functions according to the requirements of the test chip. The thickness of the pickup head 42 and the test head 44 is not limited, and can still be adapted to this pressure testing mechanism.
[0047] In this embodiment, the conveyor track 2 is sequentially provided with an infeed position, a test position, and an outlet position along a first direction. The conveyor track 2 drives the tray assembly 3 to move back and forth between the infeed position, the test position, and the outlet position. The test seat 8 is located on one side of the test position along a second direction. When the conveyor track 2 drives the tray assembly 3 to move to the infeed position, the external mechanism can place the chip to be tested on the tray assembly 3 located at the infeed position. When the conveyor track 2 drives the tray assembly 3 to move to the test position, the connecting plate 45 moves along the second direction, and the picking head 42 moves between the test seat 8 and the test position to move the chip between the test position and the test seat 8. When the conveyor track 2 drives the tray assembly 3 to move to the outlet position, the external mechanism can remove the tested chip from the pressure testing mechanism on the tray assembly 3 located at the outlet position.
[0048] In this embodiment, the material tray assembly 3 includes an infeed tray 31, a connecting block 32, and an outlet tray 33 connected in sequence. Both the infeed tray 31 and the outlet tray 33 are slidably connected to the conveyor track 2. The infeed tray 31 is used to carry the chip to be tested, and the outlet tray 33 is used to carry the chip after testing. The infeed tray 31 and the outlet tray 33 are connected by the connecting block 32, so the infeed tray 31 and the outlet tray 33 can move synchronously.
[0049] Preferably, the test position is located between the infeed position and the discharge position, and the center-to-center distance between the test position and the infeed position, the center-to-center distance between the test position and the discharge position, and the center-to-center distance between the infeed tray 31 and the discharge tray 33 are the same. When the infeed tray 31 is in the infeed position, the infeed tray 31 is used for loading, and at this time the discharge tray 33 is in the test position, and the discharge tray 33 is waiting to carry the tested chip. Therefore, the loading and placing of the tested chip on the discharge tray 33 can be performed simultaneously. When the infeed tray 31 is in the test position, the chip carried on the infeed tray 31 is waiting for testing, and the chip on the discharge tray 33 is unloaded. Therefore, the placing of the chip to be tested on the infeed tray 31 onto the test socket 8 and the unloading can be performed simultaneously, improving production efficiency.
[0050] More preferably, the first pressure rod 41 is located on the side closer to the conveying track 2 relative to the second pressure rod 43, and the center distance between the first pressure rod 41 and the second pressure rod 43 is the same as the center distance between the test position and the test seat 8. When the first pressure rod 41 is above the test position, the second pressure rod 43 is above the test seat 8, and the movement stroke of the connecting plate 45 remains unchanged each time, reducing the difficulty for the first drive assembly to drive the connecting plate 45 to move.
[0051] In this embodiment, the bracket 1 is provided with a top plate 11, and the top plate 11 is provided with an elongated through hole 111 extending along a first direction. The first pressure rod 41 and the second pressure rod 43 pass through the elongated through hole 111, and the connecting plate 45 is slidably connected to the top plate 11 along the first direction. When the connecting plate 45 moves along the second direction, the first pressure rod 41 and the second pressure rod 43 can slide within the elongated through hole 111.
[0052] Preferably, the top surface of the top plate 11 is provided with two third slide rails 51 extending along the second direction. The two third slide rails 51 are spaced apart on both sides of the elongated through hole 111. The connecting plate 45 is provided with multiple third sliders 52, which are slidably connected to the two third slide rails 51. In this embodiment, there are four third sliders 52, with each third slide rail 51 corresponding to two third sliders 52, which improves the sliding stability of the connecting plate 45.
[0053] Furthermore, a first slider 61 is provided on the side of the connecting plate 45 near the conveying track 2, and a first slide rail 62 is provided on the first pressure rod 41. The first slide rail 62 is slidably connected to the first slider 61, which improves the smoothness and accuracy of the movement of the first pressure rod 41; and / or a second slider 71 is provided on the side of the connecting plate 45 away from the conveying track 2, and a second slide rail 72 is provided on the second pressure rod 43. The second slide rail 72 is slidably connected to the second slider 71, which improves the smoothness and accuracy of the movement of the second pressure rod 43.
[0054] More preferably, such as Figure 3As shown, the bottom of the connecting plate 45 is provided with an extension block 46 extending in the vertical direction. The first slider 61 and the second slider 71 are connected to the two sides of the extension block 46 along the second direction, which increases the contact area between the first slider 61 and the second slider 71 and the connecting plate 45 and improves the connection strength.
[0055] In this embodiment, the second driving assembly includes a first driving component and a second driving component. The first driving component is driven and connected to the first pressure rod 41 for raising and lowering the first pressure rod 41; the second driving component is driven and connected to the second pressure rod 43 for raising and lowering the second pressure rod 43. Because the test pressure head 44 and the pickup pressure head 42 have different thicknesses, the raising and lowering strokes of the first pressure rod 41 and the second pressure rod 43 are different, and the first pressure rod 41 and the second pressure rod 43 are driven independently according to the stroke requirements.
[0056] It should be noted that the first drive assembly, the first drive component, and the second drive component adopt ball screw linear modules or pneumatic linear modules, both of which can drive the connecting plate 45, the first pressure rod 41, and the second pressure rod 43. This is existing technology, and the specific structure and working principle will not be described in detail here.
[0057] like Figure 1 As shown, when the thickness of the test head 44 does not exceed the safety operation requirements, the pickup head 42 can also have the function of pressure testing, and the test head 44 can also have the function of picking up chips. At this time, there are two conveying tracks 2, which are arranged at intervals on both sides of the test base 8 along the second direction. The two conveying tracks 2 correspond to the pickup head 42 and the test head 44 respectively. The pickup head 42 and the test head 44 can pick up and pressure test the chips on the two conveying tracks 2 respectively, thereby improving the testing efficiency. When the thickness of the test head 44 exceeds the safety operation requirements, the material tray assembly 3 on the conveyor track 2 on one side of the test head 44 is disassembled. The discharge tray 33 of the material tray assembly 3 is separated from the connecting block 32. The discharge tray 33 of the material tray assembly 3 is located at the discharge position, and the inlet tray 31 of the material tray assembly 3 is located at the inlet position. When the pick-up head 42 is above the test seat 8, the test head 44 moves to the conveyor track 2 on one side of the test head 44. At this time, there is no material tray below the test head 44, avoiding interference between the material tray assembly 3 and the test head 44. In this embodiment, only the material tray assembly 3 of one of the conveyor tracks 2 is disassembled. The thinner pick-up head 42 is used for picking up and placing materials, and the thicker test head 44 is used for testing. This can directly achieve the production purpose, shorten the product testing changeover cycle, and reduce labor costs.
[0058] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
