Description

Technical Field

[0001] This invention relates to the field of chip testing technology, and in particular to a mobile phone circuit chip testing device with an alarm function. Background Technology

[0002] Mobile phone chips typically refer to chips used in mobile phone communication functions, including baseband, processor, coprocessor, RF, touchscreen controller chips, memory, wireless ICs, and power management ICs. Before being packaged at the factory, the performance of the mobile phone chip itself needs to be tested to ensure it meets the usage requirements; mobile phone chip testing is an important step.

[0003] Chinese invention patent (CN113189471B) discloses a testing device for mobile phone circuit chips, including a fixing plate; a first cylinder is fixedly connected to the center of the bottom end of the bracket; an upper detection seat is fixedly connected to the output end of the first cylinder; a lower detection seat is fixedly connected to the fixing plate at a position relative to the upper detection seat; a placement groove is opened at the top of the lower detection seat; a first cavity is opened inside the lower detection seat; a testing method for mobile phone circuit chips is provided, in which the chip is placed in the test placement groove for testing. When testing mobile phone circuit chips using this testing method, the test position of the mobile phone circuit chip is adjusted by an adjustment plate to ensure the accuracy of the measurement. By closing the upper and lower detection seats, the mobile phone circuit chip is ensured to be in a dust-free testing state, thereby solving the problem that when the chip is placed in the testing machine, the contact between the chip and the probe is not tight enough, which easily leads to poor contact and incorrect test results.

[0004] In existing patented technologies, the chip is clamped by closing the upper and lower detection seats before testing. However, in actual operation, the chip's position is difficult to accurately locate before the upper and lower detection seats close together, causing the chip to become skewed. Once the chip's pins become skewed, they will be squeezed, which may lead to pin breakage and affect the chip's quality.

[0005] To address this issue, we propose a mobile phone circuit chip testing device with alarm functionality. Summary of the Invention

The clamp 503 then drives the workpiece clamping assembly 7 to move.

[0041] See Figures 6-10 The feeding assembly 3 includes a material rack fixing plate 302 and a cylinder 303. Four support columns 306 are provided below the material rack fixing plate 302. The lower ends of the four support columns 306 are fixed above the box body 1. A through hole is opened in the center of the material rack fixing plate 302, and two support plates 307 are fixed inside the through hole of the material rack fixing plate 302. A material rack 301 is fixed on the outer wall of the two support plates 307. A sliding groove is opened on the adjacent end face of the two material racks 301.

Adhesive strips are provided on the adjacent ends of the two limit plates 305. The cylinder 303 is located directly below the through hole of the material rack fixing plate 302. An adsorption seat 304 is fixed to the output end of the cylinder 303.

[0042] Through the above technical solution, the feeding component 3 is used for storing the chips to be tested, and can store chips of the same batch. The cylinder 303 can drive the adsorption seat 304 to move, and the adsorption seat 304 can adsorb the chips between the material racks 301. The cylinder 303 controls the chips to move to the workpiece clamping component 7, and the limiting plate 305 can clamp the two sides of the chip to prevent the chip from falling automatically. The support plate 307 plays the role of fixing the material rack 301, and the material rack 301 restricts the two sides of the chip for storing the chip.

[0043] See Figure 1 , Figure 2 , Figure 11 and Figure 12 The workpiece clamping assembly 7 includes a workpiece placement seat 701. A chip mounting groove 703 is formed on the upper surface of the workpiece placement seat 701, and an adsorption seat connecting hole 702 is formed in the center of the workpiece placement seat 701. A strip-shaped groove is formed in the center of the chip mounting groove 703, and a lead screw 705 is rotatably mounted within the strip-shaped groove. A side reset plate 704 is sleeved on the outside of the lead screw 705 and slidably mounted within the chip mounting groove 703. A circular groove is formed at the upper end of the workpiece placement seat 701, and a connecting wheel 708 is provided within the upper groove of the workpiece placement seat 701. The connecting wheel 708 is connected to the lead screw 705. A groove is formed on the lower surface of the workpiece placement seat 701, and a spring 707 is provided within the lower groove of the workpiece placement seat 701. Fixed rotating seats 706 are connected to both ends of the spring 707 and slidably mounted within the lower groove of the workpiece placement seat 701. The lower end of the fixed rotating seat 706 is hinged to the clamping seat 503.

[0044] The upper part of the housing 1 is provided with a placement seat plate 13 and a positioning rail 9. The placement seat plate 13 is located below the workpiece clamping assembly 7. The placement seat plate 13 limits the bottom of the workpiece clamping assembly 7 to prevent the workpiece clamping assembly 7 from shaking when it moves. The positioning rail 9 is located on the side panel of the workpiece clamping assembly 7 to limit the side of the workpiece clamping assembly 7.

[0045] Through the above technical solution, the workpiece clamping assembly 7 is used for chip placement, facilitating detection by the detection assembly 6. The adsorption seat connecting hole 702 in the center of the workpiece placement seat 701 serves to accommodate the adsorption seat 304. The adsorption seat 304 can pass through the adsorption seat connecting hole 702 to adsorb the chips between the material racks 301. The chip mounting slot 703 is used to store the chips and can fix the position of the chip body and pins. At the same time, the lead screw 705 is a reciprocating lead screw. When the lead screw 705 rotates, it can drive the side reset plate 704 to move. The side reset plate 704 pushes the chip so that the chip can be completely placed in the chip mounting slot 703. A fixed rotating seat 706 is provided below the workpiece placement seat 701. The fixed rotating seat 706 can change with the position of the clamp 503. The fixed rotating seat 706 can rotate and slide. The fixed rotating seat 706 can be adjusted when turning, so that the workpiece placement seat 701 can rotate.

[0046] See Figure 4 , Figure 4 , Figures 13-15 The detection component 6 includes a slide 603, and at least eight slides 603 are provided. Each of the eight slides 603 is rotatably provided with a clamping plate 601 and a clamping plate 602. A detection plate 604 is provided on the inner side of the clamping plate 601. The detection plate 604 is provided with fixing ears 605 around its perimeter, and a pressure seat 616 is provided at the lower end of the detection plate 604. The interior of the detection plate 604 is hollow, and a transmission rod 608 is rotatably mounted inside the detection plate 604. A servo motor 613 is also provided inside the detection plate 604. One-way bearing 606 and one-way bearing 609 are provided on the outside of the transmission rod 608. A movable plate 614 is also provided inside the detection plate 604, and two rows of movable rods 61 are provided on the lower end face of the movable plate 614. 8. A spring 619 is provided at the end of the movable rod 618 away from the movable plate 614. A pin pressure block 617 is connected to the end of the spring 619 away from the movable rod 618. The two sides of the pressure seat 616 are parallel protrusions, and through holes are opened on the two sides of the pressure seat 616. The pin pressure block 617 is slidably disposed in the through holes of the protrusions. The output end of the servo motor 613 is connected to the worm gear 612. The worm gear 612 is driven by a worm wheel 611, which is sleeved on the outside of the transmission rod 608.

[0047] Through the above technical solution, the detection component 6 detects the chip on the workpiece clamping component 7, accurately aligning it with the chip's pins and preventing damage to the pins during detection. Clamping plates 601 and 602 can rotate on the slide 603, clamping them to the outside of the workpiece placement seat 701. Simultaneously, the pressure seat 616 below the detection plate 604 can lock into the chip mounting slot 703, limiting the chip's position within the slot. The servo motor 613 drives the worm gear 612 to rotate the worm wheel 611 and the transmission rod 608 in either the forward or reverse direction. 08 can drive one-way bearing 606 or one-way bearing 609 to rotate in either forward or reverse direction. One-way bearing 606 or one-way bearing 609 can drive drive wheel 607 or cam 610 to rotate. Cam 610 pushes movable plate 614 downward, so that movable plate 614 can drive movable rod 618, spring 619 and pin pressure block 617 to move downward. Pin pressure block 617 docks with pin. Moreover, drive wheel 607 can dock with connecting wheel 708. When drive wheel 607 rotates, it can drive connecting wheel 708 to rotate. Connecting wheel 708 drives lead screw 705 to rotate, which is used to drive lead screw 705 to rotate.

[0048] The pin pressure block 617 is electrically connected to the control component 4, which includes a PLC control unit and an alarm unit. The PLC control unit controls the current and voltage so that the current can enter the chip through the pin pressure block 617 to detect the chip's circuit. If the chip has a circuit fault, the PLC control unit can sense the change in current and voltage to check the chip's circuit condition and issue an audible and visual alarm through the alarm unit to remind the staff.

[0049] See Figure 13 and Figure 15 A cam 610 is sleeved on the outside of the one-way bearing 609, and the cam 610 is located directly above the movable plate 614. A groove matching the position of the cam 610 is opened on the upper part of the movable plate 614. A drive wheel 607 is sleeved on the outside of the one-way bearing 606. A spring 620 is fixed on the lower end face of the movable plate 614, and the lower end of the spring 620 is fixed on the inner wall of the detection plate 604.

[0050] Through the above technical solution, when the transmission rod 608 rotates in the forward or reverse direction, it can independently trigger the one-way bearing 606 or the one-way bearing 609 to control the rotation of the drive wheel 607 or the cam 610. When the one-way bearing 609 rotates, it can drive the cam 610 to rotate. The cam 610 can match the groove on the upper end face of the movable plate 614, and the groove can lock the position of the cam 610. At the same time, the cam 610 can push the movable plate 614 to move downward, controlling the position of the movable plate 614. Moreover, after the cam 610 separates from the groove on the upper end face of the movable plate 614, the spring 620 can push the movable plate 614 back to its original position, resetting the movable plate 614.

[0051] See Figure 11 and Figure 13 The outer wall of the detection plate 604 is provided with a connecting hole 615, and the connecting hole 615 corresponds to the position of the drive wheel 607.

[0052] With the above technical solution, the connecting hole 615 is located at the position of the driving wheel 607, so that the connecting wheel 708 can pass through the connecting hole 615 and connect with the driving wheel 607. The driving wheel 607 can drive the connecting wheel 708 to rotate, which in turn drives the lead screw 705 to rotate, so that the lead screw 705 can drive the side reset plate 704 to move. The side reset plate 704 pushes the chip, so that the chip can be accurately moved into the chip mounting slot 703.

[0053] See Figure 1 , Figure 2 and Figure 3 The positioning and detection component 8 includes a bracket 801. The lower end of the bracket 801 is fixed to the upper end of the housing 1. A connecting plate 802 is fixed to the upper end of the bracket 801. A shooting frame 803 is provided on one side of the connecting plate 802. A through hole is opened in the center of the shooting frame 803, and a CCD camera is installed in the through hole of the shooting frame 803. The shooting frame 803 is located above the conveying component 5.

[0054] Through the above technical solution, the positioning and detection component 8 is used to fix the CCD camera, which takes pictures of the chip on the workpiece clamping component 7. The CCD camera transmits the captured information to the PLC control unit, which identifies the position of the chip on the workpiece clamping component 7.

[0055] See Figures 1-5 The fixed wheel 2 is cylindrical on the outside, and a built-in fixed barrel 11 is provided in the center of the fixed wheel 2. Bearings 12 are provided on both sides of the built-in fixed barrel 11. A fixed seat 10 is sleeved on the outside of the bearings 12. The fixed seat 10 is fixed to the upper end face of the box body 1. A through hole is opened on the upper end face of the box body 1, which matches the external shape of the fixed wheel 2 and the detection component 6.

[0056] Through the above technical solution, the fixed wheel 2 serves to fix the detection component 6. By setting different detection components 6 at different detection locations, different chips are detected. The bearing 12 and the fixed seat 10 are used to fix the position of the built-in fixed barrel 11, so that the built-in fixed barrel 11 and the fixed wheel 2 can rotate, thus controlling the rotation of the detection component 6. Example 2

[0057] Based on the mobile phone circuit chip testing device with alarm function provided in the first embodiment of this application, the second embodiment of this application proposes another mobile phone circuit chip testing device with alarm function. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0058] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments. Based on the first embodiment, the difference between this second embodiment and the first embodiment is that this second embodiment also has: a lower stabilizing plate 17 is provided below the clamping plate 2 602, a through hole is opened on one side of the lower stabilizing plate 17, a connecting rod 19 is inserted into the through hole on one side of the lower stabilizing plate 17, a movable frame 18 is fixed to the other end of the connecting rod 19, a cylinder 3 16 is installed on the movable frame 18, and a limit seat 14 is provided on the side of the cylinder 3 16; The bottom of the limit seat 14 is provided with an inclined cylinder 15, and the output end of the cylinder 15 is connected to a gripper corresponding to the position of the detection component 6.

[0059] Through the above technical solution, cylinder 3 16 can drive the connecting rod 19 to move through the moving frame 18, so that the connecting rod 19 can dock with the lower stabilizing plate 17, increasing the stability of clamping plate 2 602. Cylinder 2 15 is used to drive the gripper, and the gripper can control clamping plate 1 601 to rotate.

[0060] The difference between Embodiment 2 and Embodiment 1 is that the moving frame 18 is moved by the cylinder 3 16, so that the connecting rod 19 outside the moving frame 18 can be locked in the lower stabilizing plate 17, increasing the stability of the lower stabilizing plate 17 and the clamping plate 2 602. At the same time, the cylinder 2 15 can drive the gripper to move, so that the gripper can control the position of the clamping plate 1 601, so that the clamping plate 1 601 can clamp the chip.

[0061] The working principle of this invention is as follows: First, the chip to be tested is placed in the material rack 301. Then, the drive motor drives the conveyor rod 504 to rotate. The conveyor rod 504 then drives the transmission wheel 502 and the conveyor belt 501 to rotate. The clamp 503 outside the conveyor belt 501 can move the workpiece clamping assembly 7 to the position of the adsorption seat 304. Then, the cylinder 303 is activated. The cylinder 303 drives the adsorption seat 304 to pass through the adsorption seat connecting hole 702 to adsorb the chip. Then, the cylinder 303 controls the adsorption seat 304 and the chip to move into the chip mounting slot 703. At the same time, the limiting plate 305 can hold the chip above to prevent the chip from falling. Then, the conveyor belt 501 drives the workpiece clamping assembly 7 to the position of the positioning detection assembly 8. The CCD camera on the positioning detection assembly 8 takes a picture of the chip and determines the position of the chip on the workpiece clamping assembly 7. Then, the conveyor belt 501 drives the workpiece clamping assembly 7 to the position of the detection assembly 6 for detection. The gripper is moved by cylinder 215, which controls the rotation of clamping plate 601, allowing the detection plate 604 on one side of clamping plate 601 to fit against the workpiece placement seat 701. If the chip becomes misaligned, servo motor 613 is activated. Servo motor 613, worm gear 612, and worm wheel 611 control the transmission rod 608 to rotate forward. One-way bearing 606 drives drive wheel 607 to rotate, which in turn drives connecting wheel 708 through connecting hole 615. Connecting wheel 708 drives lead screw 705 to rotate, which in turn moves side reset plate 704, allowing it to push the chip into chip mounting slot 703. Afterwards, the servo motor 613 and worm gear 612... 2. The worm gear 611 controls the transmission rod 608 to rotate in the opposite direction. The transmission rod 608 drives the cam 610 to rotate through the one-way bearing 609. The cam 610 can push the movable plate 614 to move downward. The movable plate 614 can move downward through the movable rod 618, spring 619 and pin pressure block 617. The pin pressure block 617 can enter into the chip mounting slot 703 and connect with the chip's pins. Then, the PLC control unit controls the current and voltage to allow the current to enter the chip through the pin pressure block 617 to detect the chip's circuit. If the chip has a circuit fault, the PLC control unit can sense the change in current and voltage to check the chip's circuit condition. At the same time, the PLC control unit controls the alarm unit to issue an alarm to remind the staff.

[0062] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
