Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically to an explosion-proof testing device for chip packaging processing. Background Technology

[0002] A chip is a very precise semiconductor device. Its internal circuit structure and components are tiny and easily damaged by external physical factors. In order to protect the internal circuit structure and components, an insulating encapsulation shell is usually installed on the outside. This type of chip is also called a packaged chip. Packaged chips also need to undergo explosion-proof testing during the production process.

[0003] After undergoing explosion-proof testing, the reliability and stability of packaged chips can be better verified. The environmental simulation tests, electrical safety tests, and mechanical safety tests involved in the explosion-proof testing process can identify potential problems that may occur in the chip under various extreme conditions, thereby ensuring the production quality of packaged chips.

[0004] However, in practice, due to the small size of the chips and the fragility of their pins, the pins are easily subjected to stress during large-scale transportation using mechanical structures, which can lead to bending or even breakage. This requires workers to place each chip individually onto a testing instrument for inspection, which is inefficient and unsuitable for large-scale chip testing. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 This utility model embodiment provides an explosion-proof testing device for chip packaging processing, including an explosion-proof tester 5. The explosion-proof tester 5 has a conveying structure on its side, and a frame 1 is installed at the bottom of the conveying structure. The side of the frame 1 is fixedly connected to the explosion-proof tester 5.

[0032] The conveying mechanism includes a carrier 2 fixedly connected to the top of the frame body 1. The carrier 2 has two parallel carrier side plates 21, which are fixedly connected by connecting plates 22 at both ends. A rectangular groove is provided in the carrier side plate 21, and a mounting plate 23 for mounting pin contact assembly 9 is fixedly connected in the rectangular groove.

[0033] In this embodiment, both ends of the bearing side plate 21 are movably connected to drive rollers 3. The drive rollers 3 have belt rollers 31, and both ends of the belt rollers 31 are integrally provided with drive shafts 33. Both sides of the drive shafts 33 are interactively connected to the bearing side plate 21.

[0034] Furthermore, both sides of the belt roller 31 are integrally provided with edge protrusions 32, and the outer side of the belt roller 31 is also sleeved with a chip conveyor belt 4, and the edge protrusions 32 are located on both sides of the chip conveyor belt 4.

[0035] Furthermore, the chip conveyor belt 4 has pin insertion holes 41 arranged in a rectangular array, and the outer side of the belt roller 31 has pin grooves 34 arranged in a rectangular array corresponding to the pin insertion holes 41. In addition, a guide discharge seat 10 is inserted into the pin groove 34 on either side.

[0036] Furthermore, the guide discharge seat 10 has a fixing plate 101 fixedly connected to the edge protrusion 32. An inclined guide plate 102 corresponding to the pin groove 34 is fixedly connected in a rectangular array above the fixing plate 101, and one end of the inclined guide plate 102 away from the fixing plate 101 is inserted into the inner side of the pin groove 34.

[0037] Furthermore, the pin contact assembly 9 includes an insulating base 91, an integrally formed spacer plate 93 on the upper part of the insulating base 91, and conductive contact pieces 92 embedded on both sides of the spacer plate 93 above the insulating base 91.

[0038] More specifically, the rectangular groove in the bearing side plate 21 is fixedly connected to both ends of a limiting sliding post 24, and the four corners of the insulating seat 91 are fixedly connected to a connecting hole plate 94 corresponding to the limiting sliding post 24, and the limiting sliding post 24 passes through the connecting hole plate 94 and is slidably connected to the connecting hole plate 94.

[0039] Furthermore, the bottom of the insulating base 91 is provided with a servo motor 95 that is fixedly connected to the mounting plate 23, and the output shaft end of the servo motor 95 is interference-fitted with a rotary cam 96, and the rotary cam 96 contacts the bottom of the insulating base 91.

[0040] More specifically, a screen bracket 6 is also fixedly connected to the bearing side plate 21 on any one side, and a data display screen 7 is fixedly connected to the other end of the screen bracket 6. The data display screen 7 is connected to the explosion-proof detector 5 through wires, and the explosion-proof detector 5 is connected to the conductive contact 92 through wires.

[0041] By adopting the above technical solution, a robotic arm places the chips one by one onto the chip conveyor belt 4, and the chip pins are inserted into the pin sockets 41 in appropriate positions. When the belt roller 31 rotates, the chip conveyor belt 4 rotates due to friction, moving the chips above the insulating base 91. After the sensor on the side of the explosion-proof detector 5 detects the chip, it controls the servo motor 95 to rotate. The rotating cam 96 at the end of the servo motor 95 pushes the insulating base 91 upward, so that the conductive contact 92 on the insulating base 91 contacts the chip pins. After the chip is detected, it continues to move with the chip conveyor belt 4. When the chip moves above the inclined guide plate 102, the inclined surface of the inclined guide plate 102 will cause the pins to move upward, thereby pushing the pins out from the inside of the pin sockets 41. The chip is automatically discharged when it rotates to the end of the chip conveyor belt 4 and falls by gravity. The conveyor mechanism performs a continuous flow detection of the chips, which improves efficiency without damaging the pins.

[0042] In this embodiment, a drive motor 8 is fixedly connected to the end of the bearing side plate 21 on any side, and the output shaft of the drive motor 8 is connected to the drive shaft 33 at any end through a coupling. The drive motor 8 drives the belt roller 31 to rotate through the coupling, and the belt roller 31 drives the chip conveyor belt 4 to move through friction.

[0043] Furthermore, the inclined guide plate 102 is located below the pin socket 41, and the inclined guide plate 102 and the pin socket 41 are correspondingly arranged. Moreover, the end of the inclined guide plate 102 away from the belt roller 31 is inclined, and the chip pins are pushed out through the inclined surface, thereby realizing automatic feeding.

[0044] Furthermore, the explosion-proof detector 5 is equipped with a photoelectric sensor on the side near the carrier 2, and the explosion-proof detector 5 is electrically connected to the servo motor 95 through a wire. When the chip moves with the chip conveyor belt 4 to the designated position above the insulating seat 91, the photoelectric sensor will transmit the detection signal to the explosion-proof detector 5, and the explosion-proof detector 5 will control the drive motor 8 to stop rotating and control the servo motor 95 to rotate.

[0045] More specifically, the explosion-proof detector has an electrical measurement circuit inside. The chip is electrically connected to the electrical measurement circuit through a conductive contact 92. After the contact is powered on, the electrical measurement circuit will monitor the electrical parameters of the chip in real time. Since the electrical parameters of the chip, such as current, voltage, and resistance, are relatively stable under normal working conditions, these electrical parameters will change significantly when a short circuit or leakage occurs inside the chip. The changes in these data are used to test the explosion-proof performance of the chip, and the test results are displayed on the data display screen 7.

[0046] The working principle of this utility model is as follows: In use, a robotic arm first places the chips one by one onto the chip conveyor belt 4, and the chip pins are inserted into the appropriate pin sockets 41. The drive motor 8 drives the belt roller 31 to rotate via a coupling, and the belt roller 31 moves the chip conveyor belt 4 through friction until the chip conveyor belt 4 moves the chips above the insulating base 91. At this point, the photoelectric sensor on the side of the explosion-proof detector 5 detects the position of the chip and transmits the signal to the explosion-proof detector 5. The explosion-proof detector 5 then controls the drive motor 8 to stop rotating and causes the servo motor 95 to drive the rotating cam 96 to rotate, thus pushing the insulating base 91. 1. Moving upwards, the conductive contact 92 above the insulating base 91 contacts the chip's pins, electrically connecting the chip to the electrical measurement circuit inside the explosion-proof detector 5, thereby monitoring the chip's usage data in real time and determining the explosion-proof performance of the chip. After the measurement is completed, the pin contact assembly 9 resets, and the chip conveyor belt 4 drives the chip to continue moving. During the movement, the inclined guide plate 102 pushes the chip's pins to move in the opposite direction, thereby separating the pins from the inside of the pin socket 41. The chip moves to the end of the chip conveyor belt 4 and falls due to gravity, achieving automatic discharge. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
