Description

Technical Field

[0001] The invention relates to the field of electrical conductivity testing, in particular to a device for testing the electrical conductivity of component packaging. Background Art

[0002] Component packaging is the components installed on the circuit board. Packaging refers to connecting the circuit pins on the silicon chip to the external joints with wires so as to connect with other devices. It not only plays the role of installing, fixing, sealing, protecting the chip and enhancing the electrical and thermal performance, but also connects the pins of the package shell with wires through the contacts on the chip. These pins are connected to other devices through wires on the printed circuit board, thereby realizing the connection between the internal chip and the external circuit. After the component packaging is completed, it is necessary to conduct a conductivity test to determine whether the component is damaged after packaging and whether its internal circuit is connected. The pins of the packaged components are connected to the test circuit, and the feedback from the test circuit is used to determine whether the internal circuit of the packaged components is damaged; because the packaged components are easily affected in different environments such as packaging, transportation, and feeding, the pins of the packaged components will be bent to different degrees, and the bending degree and bending direction of each pin in the same packaged component are different, which makes it difficult to ensure that each pin is connected to the test circuit during the test, resulting in low accuracy of the test results and prone to misjudgment.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0027] Embodiment 1: Figures 1 to 8As shown, a conductive performance test device for component packaging includes a conveying mechanism, an automatic feeding mechanism and a testing mechanism. The conveying mechanism includes a conveying track 1 and a conveying bracket 2. The conveying track 1 is installed on the conveying bracket 2. The package is inverted on the conveying track 1. The automatic feeding mechanism is arranged at the end of the conveying track 1. The automatic feeding mechanism includes a hollow feeding box 3. Two groups of feeding components are symmetrically arranged in the hollow feeding box 3. A space for the pins of the package to pass through is formed between the two groups of feeding components. The feeding component includes an annular conveyor line and a support plate 4. The annular conveyor line is provided with a plurality of support plates 4 at equal intervals along its own path direction. The height of the input end of the conveying track 1 is higher than that of the output end. The top surface of the conveying track 1 is provided with an inverted T-shaped slide groove 19 along its own track direction. An inverted T-shaped chute 19 runs through both ends of the conveying track 1 in the length direction. A vibrator is arranged on the conveying bracket 2. The vibrator is used to vibrate the conveying track 1. A baffle 20 is connected to the output end of the conveying track 1. A discharge notch 21 is opened on one side of the conveying track 1. A push cylinder 22 is installed on the other side. A push tube 23 is connected to the telescopic shaft of the push cylinder 22. The push tube 23 is movably inserted into the inverted T-shaped chute 19 to push the package out of the discharge notch 21. A flip conveying mechanism is arranged between the automatic feeding mechanism and the conveying mechanism. The flip conveying mechanism includes a conveying frame 24. A conveying slide 25 is slidably arranged on the conveying frame 24. The conveying slide 25 moves in the horizontal direction. A feeding cylinder 26 is horizontally installed on the conveying slide 25. The feeding cylinder 26 The telescopic shaft is connected to a feeding base 27, a rotating base 28 is rotatably provided on the feeding base 27, a C-shaped clamp 29 is connected to the rotating base 28, the opening of the C-shaped clamp 29 faces the discharge notch 21, and the width of the C-shaped clamp 29 is smaller than the length of the packaged component, and the packaged components slide into one end of the inverted T-shaped chute 19 of the conveying track 1, the length direction of the packaged components is parallel to the length direction of the conveying track 1, and the width of the inverted T-shaped chute 19 is slightly larger than the width of the packaged components, so that the packaged components can move in the inverted T-shaped chute 19 along the length direction of the conveying track 1, the packaged components move inverted in the inverted T-shaped chute 19, and the pins of the packaged components pass through the top of the inverted T-shaped chute 19, so that the pins of the packaged components are exposed upwards. Exposure ensures that the pins will not be bent or broken during the conveying process. Since the conveying track 1 is arranged to tilt downward in the conveying direction, the conveying track 1 is vibrated in cooperation with the vibrator. Under the action of vibration and the gravity of the components, the packaged components are moved toward the baffle 20 along the length direction of the conveying track 1. When the packaged components contact the baffle 20, the packaged components move to the end position. At this time, the vibrator stops running, and the push cylinder 22 drives the push tube 23 to move toward the packaged components. The packaged components are pushed out from the discharge notch 21 through the push tube 23, so that the packaged components move into the C-shaped clamp 29. The contact position between the C-shaped clamp 29 and the packaged components is located between the two pairs of pins of the packaged components. The packaged components are clamped by the C-shaped clamp 29, and then,The packaged components are transported close to the hollow loading box 3 by the movement of the conveying slide 25. During the conveying process, the rotating base 28 deflects 180°, thereby driving the C-shaped clamp 29 to flip 180°, which is used to turn the packaged components over so that the pins of the packaged components face downward and are in a testing posture. Then, the packaged components are placed on the loading assembly of the hollow loading box 3 through the C-shaped clamp 29, that is, the two ends of the packaged components in the length direction are respectively in contact with the support plates 4 of the two groups of loading assemblies, and the pins of the packaged components are suspended between the two groups of loading assemblies, thereby avoiding damage or bending to the pins during the loading process. It is used to stack the packaged components to be tested in the hollow loading box 3, and the packaged components are transported from top to bottom in sequence through the circular movement of the support plate 4, so that the packaged components can be automatically loaded into the testing mechanism, and the conductive performance of the packaged components is tested by the testing mechanism, and the support plate 4 of the lower packaged components moves circularly to the upper side for reloading, thereby realizing a cyclic automatic loading and unloading operation.

[0028] Furthermore, if Figures 1 to 6 As shown, the annular conveyor line includes an active roller 43 and a driven roller 44. The two opposite side walls of the hollow feeding box 3 are provided with installation windows 45 connected to the inner hole. The active roller 43 and the driven roller 44 are arranged in the installation windows 45 from top to bottom. The active roller 43 and the driven roller 44 are both rotatably connected to the hollow feeding box 3. The active roller 43 is connected to the driven roller 44 through an annular belt 46. The support plate 4 is installed on the annular belt 46. A side wall of the hollow feeding box 3 where no feeding component is provided is provided with an avoidance window 47 from top to bottom. The C-shaped clamp 29 can move from the avoidance window 47 to the hollow feeding box 3. Each group of feeding components is correspondingly provided with a feeding motor, which is installed on the side wall of the hollow feeding box 3. The output shaft of the feeding motor is connected to the active roller 43, and the feeding motor drives the active roller 43 to rotate. The active roller 43 drives the driven roller 44 to rotate through the annular belt 46, so that the annular belt 46 moves in a circular path, thereby driving The support plate 4 on the endless belt 46 moves in a circular motion, so that the support plate 4 moves from top to bottom to load the packaged components onto the testing mechanism, and the loading of the support plate 4 can be cyclically performed, and the feeding cylinder 26 drives the C-shaped clamp 29 to move close to the hollow loading box 3, so that the packaged components move from the top of the hollow loading box 3 into the hollow loading box 3, and the C-shaped clamp 29 enters the hollow loading box 3 through the avoidance window 47, so that the C-shaped clamp 29 will not interfere with the hollow loading box 3. At this time, the C-shaped clamp 29 is located between the two groups of loading components. When the packaged components fall on two opposite support plates 4, the feeding cylinder 26 contracts and drives the C-shaped clamp 29 to move out of the hollow loading box 3. Since the size of the packaged components is larger than the size of the avoidance window 47, the packaged components cannot be moved out of the hollow loading box 3, so that the packaged components remain in the hollow loading box 3, thereby automatically loading the packaged components output by the conveying track 1 into the hollow loading box 3.

[0029] Embodiment 2: Based on Embodiment 1, Figures 1 to 3 As shown, the test mechanism includes a test platform 5 and a vacuum feeding tube 6. The test platform 5 is located directly below the hollow loading box 3. The vacuum feeding tube 6 is slidably mounted on the test platform 5. The vacuum feeding tube 6 has the freedom to move along the height direction of the test platform 5. A test circuit board is arranged in the test platform 5. A test board 7 is mounted on the test platform 5. A test hole 8 is provided on the test board 7 at a position corresponding to the pin of the package. A test component is arranged in the test hole 8. The test component includes a hollow test tube 9 and a conductive sheet 10. The hollow test tube 9 is fixed in the test hole 8, the conductive sheet 10 is slidably arranged in the hollow test tube 9, the conductive sheet 10 has the freedom to move along the height direction of the hollow test tube 9, the conductive sheet 10 is connected to the test circuit board through the wire 11, the packaged components at the bottom of the hollow loading box 3 are in the loading state, and the bottom support plate 4 moves and gradually separates from the packaged components. At this time, the vacuum feeding tube 6 moves upward, so that the vacuum feeding tube 6 extends into the hollow loading box 3 to contact the packaged components, and the vacuum feeding tube 6 absorbs the packaged components by negative pressure. , so that the packaged components will not be offset during the loading process to the test mechanism, making the loading more accurate, the vacuum feeding tube 6 drives the packaged components to move downward, when the support plate 4 is separated from the packaged components thereon, the vacuum feeding tube 6 drives the packaged components to be loaded onto the test board 7, the test holes 8 on the test board 7 correspond to the pins on the packaged components one by one, so that the pins of the packaged components are inserted into the corresponding test holes 8, the conductive sheet 10 can cover the circumferential direction of the entire test hole 8, when the pin enters the test hole 8, the conductive sheet 10 moves upward close to the pin of the packaged component, because the conductive sheet 10 can cover the circumferential direction of the entire test hole 8, so that the conductive sheet 10 can smoothly contact the pin of the packaged component, and the conductive sheet 10 can move the corresponding height according to the bending condition of the pin, so that each conductive sheet 10 can contact the corresponding pin, so that the pin is connected to the test circuit board through the wire 11, so as to judge the conductive performance of the packaged component according to the connection condition, judge whether the internal circuit of the packaged component is damaged, and then judge whether the packaged component is put into use.

[0030] Embodiment 3: Based on Embodiment 2, Figure 2 and Figure 3As shown, the inner hole of the hollow test tube 9 is composed of a coaxial conical hole 12 and a cylindrical hole 13, the small diameter end of the conical hole 12 is connected to the top of the cylindrical hole 13, an annular electromagnet 14 is installed at the bottom of the hollow test tube 9, a spring 15 is connected to the bottom of the conductive sheet 10, and the end of the spring 15 away from the conductive sheet 10 is connected to the inner ring of the annular electromagnet 14, a cylinder 16 is vertically arranged in the test platform 5, a vertical thin rod 17 is connected to the telescopic shaft of the cylinder 16, a vacuum feeding pipe 6 is connected to the top of the vertical thin rod 17, a circular hole 18 for the vacuum feeding pipe 6 to pass through is opened on the test plate 7, and the vacuum feeding pipe 6 is connected to the vacuum pump through a negative pressure pipe. Under normal conditions, the annular electromagnet 14 is energized to attract the conductive sheet 10, so that the conductive sheet 10 compresses the spring 15. The extension and retraction of the air cylinder 16 drives the vertical thin rod 17 to move up and down, so as to load the packaged components in the hollow loading box 3 onto the test board 7 for conductivity test. The large diameter end of the tapered hole 12 allows the bent pins to enter the tapered hole 12, and the conductivity test can be performed on most packaged components with bent pins. When the pins enter the tapered hole 12, the pins are guided under the tapered inner wall of the tapered hole 12, so that the pins of the packaged components can be smoothly inserted into the cylindrical holes 13. When the packaged circuit board contacts the test board 7, the annular electromagnet 14 is powered off, and the conductive sheet 10 moves upward under the reaction force of the spring 15, so that the conductive sheet 10 contacts the pins. The spring 15 can adapt to the height of the pins, so that the conductive sheet 10 smoothly contacts the pins to complete the conductivity test.

[0031] Embodiment 4: Based on Embodiment 3, Figure 1 , Figure 4 and Figure 5As shown, both ends of the test platform 5 are provided with a feeding mechanism, which includes a conveyor belt 48 and a feeding frame 49. The feeding frame 49 is installed on the conveyor frame of the conveyor belt 48. A feeding cylinder 50 is horizontally installed on the feeding frame 49. The telescopic shaft of the feeding cylinder 50 is connected to a feeding base 51. The end of the feeding base 51 close to the vacuum feeding pipe 6 is connected to a negative pressure feeding pipe 52 through the rotation of the main shaft. The end of the feeding base 51 away from the negative pressure feeding pipe 52 is installed with a driving motor 53. The output shaft of the driving motor 53 is connected to the main shaft. One of the feeding mechanisms feeds the packaged components with qualified test quality, and the other feeding mechanism feeds the packaged components with unqualified test quality. The corresponding feeding mechanism is started according to the test result. Specifically, when the test is completed, the vacuum feeding pipe 6 contacts the packaged components again and vacuum adsorbs them, and the cylinder 16 extends to lift the vacuum feeding pipe 6 to lift the packaged components. Components, so that the pins of the packaged components are moved out of the test hole 8, and then the unloading mechanism corresponding to the test result is started, and the unloading cylinder 50 drives the negative pressure unloading pipe 52 to move close to the packaged components. The negative pressure unloading pipe 52 is connected to the vacuum pump through a pipeline, and the packaged components are adsorbed by negative pressure. Then the negative pressure of the vacuum feeding pipe 6 is disconnected, and the unloading cylinder 50 contracts, so that the negative pressure unloading pipe 52 drives the packaged components to move above the conveyor belt 48. During the movement, the driving motor 53 drives the main shaft to rotate, so that the negative pressure unloading pipe 52 drives the packaged components to flip 180°, so that the pins of the packaged components face upward, and then the negative pressure of the negative pressure unloading pipe 52 is disconnected, so that the packaged components fall on the conveyor belt 48, and the pins of the packaged components face upward, so that the packaged components will not cause damage to the pins during transportation, and the packaged components are transported to the next processing station for processing via the conveyor belt 48.

[0032] Furthermore, if Figures 1 to 6As shown, the top surface of the test platform 5 is provided with a mounting slot 54 connected to its own inner cavity, and an annular support platform 55 is fixed to the inner wall of the mounting slot 54. The test board 7 is arranged in the mounting slot 54, and the test board 7 is installed on the annular support platform 55 by screws. Different packaged components are correspondingly provided with test boards 7, and the sizes of different test boards 7 are the same, so that they can all be installed in the mounting slot 54. The difference is that the positions of the test holes 8 on the test board 7 are different, which are arranged according to the pin positions of the corresponding packaged components, and are installed according to the types of packaged components. For the corresponding test board 7, first connect the wire to the test circuit board, then place the test board 7 on the annular support table 55, and finally tighten the screws to complete the installation of the test board 7. The corresponding test board 7 can be installed according to the type of packaged components, so as to meet the conductivity performance test of different types of packaged components and has a wide range of uses; secondly, the bottom of the hollow loading box 3 is installed on the test platform 5 through two 7-shaped frames, and the 7-shaped frames are connected to the hollow loading box 3 by bolts, so that the hollow loading box 3 can be replaced with a hollow loading box 3 of a corresponding size according to the size of the packaged components.

[0033] Embodiment 5: Since the width of the inverted T-shaped chute 19 is slightly larger than the width of the packaged component, the packaged component is easily tilted after contacting the baffle 20, resulting in the C-shaped clamp 29 being unable to accurately clamp the packaged component and unable to load the packaged component into the hollow loading box 3. Therefore, based on the embodiment 4, as shown in FIG. Figures 1 to 5As shown, a positioning plate 30 is provided on one side of the C-shaped clamp 29, and the positioning plate 30 is connected to the conveying bracket 2.

The packaged components are pushed into the C-shaped clamp 29 through the pushing tube 23, and the packaged components are made to contact the inner wall of the C-shaped clamp 29. At this time, the two ends of the packaged components in the width direction respectively contact the C-shaped clamp 29 and the pushing tube 23 to complete the positioning. The positioning plate 30 is connected to the vacuum pump through a negative pressure hose. Similarly, the C-shaped clamp 29 is connected to the vacuum pump through a hose to generate a vacuum in the negative pressure chamber, so that the negative pressure holes 31 generate suction to attract the packaged components. To ensure the smooth movement of the packaged components, the roller 32 of the push tube 23 contacts the packaged components, and the bottom wall and side wall of the C-shaped clamp 29 are smoothed. Under the action of suction, one end of the packaged component in the length direction contacts the positioning plate 30 to complete the positioning, thereby realizing the lateral and longitudinal positioning of the packaged components. Then the negative pressure of the negative pressure holes 31 is disconnected, and the negative pressure pores 33 generate vacuum suction to adsorb the packaged components, so that the packaged components are stably limited in the C-shaped clamp 29, so that the flipping and conveying mechanism can accurately stack the packaged components in the hollow loading box 3.
