Description

Technical Field

[0001] The present invention relates to the technical field of chip testing, and in particular to a chip loading device for chip testing equipment with high supply efficiency. Background Art

[0002] As the chip usage environment becomes more complicated, various industries have higher requirements for the stable electrical parameter performance of chips in high-temperature environments. Manufacturers need to test the high-temperature resistance of chips after production. That is, after heating the working chip to a certain temperature, the current working status of the chip is detected to determine whether it still meets the predetermined working performance. At present, when testing the stability of the chip under high-temperature conditions, the chip is often heated in a confined space to heat the chip to a specified temperature, and the working status of the chip at this temperature is tested.

[0003] When using the existing chip performance testing equipment, the chip needs to be manually placed into the testing equipment once, and then the chip is subjected to high-temperature testing. During the chip loading process, manual loading is not only slow, but also requires the loading and unloading of the chip to be carried out separately, resulting in slow process progress. In addition, the chip after testing is still in a high-temperature state. Even if the worker wears protective equipment, there is still a certain operational risk. Therefore, a chip loading device with high supply efficiency for chip testing equipment is proposed. Summary of the invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention provides a single loading assembly and a steering assembly, and does not require manual insertion of the circuit board into the test equipment body. Instead, multiple circuit boards can be inserted into the transfer insert in sequence manually or by a mechanical arm, thereby effectively avoiding direct docking between the loading station and the test station, ensuring the safety of the loading operation, and improving the chip loading and supply efficiency through batch automatic transportation and docking of the circuit boards;

[0018] 2. The present invention sets two single-body loading components so that the two single-body loading components correspond to two loading stations. After the test of the first batch of chips is completed, the second single-body loading component moves to the location of the test equipment body for transportation and docking. At this time, the staff or the robot arm can take down the first batch of circuit boards and start the next round of loading, so that the loading of the second batch of circuit boards can be completed before the test of the previous batch of chips is completed, eliminating the waiting time between the loading of the two batches of chips, and further improving the feeding efficiency;

[0019] 3. The present invention sets a positioning block so that after the electric lifting slide drives multiple transfer inserts to rise or fall collectively, the steering lever is always located at the tail end of one of the transfer inserts. At this time, the laser rangefinder on the top side of the bogie will measure the distance of the positioning block on one side of the transfer insert, thereby realizing laser positioning, preventing the transfer insert from being misplaced due to the inadequate lifting action of the electric lifting slide, thereby affecting the loading, transfer, and docking processes of the circuit board and the chip;

[0020] 4. The present invention sets a limit rod, so that when the robot arm loads the circuit board, the current loading monomer loading component will be in front of the limit frame. After the laser rangefinder is positioned, the electric slider carries multiple transfer inserts and moves a certain distance toward the position of the limit frame until the limit rod at one end of the limit frame is inserted into the limit hole on one side of the current transfer insert, thereby locking the transfer insert to prevent the transfer insert from being offset due to the vibration generated during the insertion of the circuit board into the transfer insert, thereby affecting the accuracy of subsequent processes;

[0021] 5. The present invention sets a trapezoidal guide plate so that when the limit rod is inserted into the limit hole, the trapezoidal guide plate will dock with the opening of the transfer insert. At this time, the staff or the robot arm can insert the circuit board into the transfer insert through the trapezoidal guide plate. The trapezoidal guide plate with a trapezoidal structure can play a guiding role, so that the circuit board entering the trapezoidal guide plate can be automatically inserted into the transfer insert, thereby reducing the time spent on the mutual positioning of the circuit board and the transfer insert, and improving the loading speed;

[0022] 6. The present invention provides an elastic rubber sleeve so that when the circuit board is inserted into the transfer insert, the elastic rubber sleeve is squeezed, causing the elastic rubber sleeve to produce elastic deformation, thereby applying reverse pressure to the circuit board, so that the circuit board can be stably inserted into the transfer insert without falling off due to the centrifugal force of the transfer insert turning. When the transfer insert is docked with the test end, the sealing rubber pad will be stuck in the test interface, playing a role of sealing and heat insulation, reducing the loss of heat inside the insulation tank during the test process;

[0023] 7. The present invention sets a linkage magnetic suction plate so that the linkage magnetic suction plate can use magnetic suction force to keep the steering lever and the current transfer insert in an adsorbed state. When the steering lever is reset, the elastic force of the annular reset spring can drive the transfer insert to reset, thereby ensuring that the transfer insert reset action is executed in place. During the loading process of the transfer insert, each connecting rod will be adsorbed with the positioning magnetic suction block, and the elastic force of the annular reset spring will keep each transfer insert in a limited state, thereby preventing the transfer insert from being offset due to vibration during the loading process, thereby affecting the positioning accuracy.

Figure 3 As shown, two horizontally arranged and mutually parallel transposition linear guide rails 4 are fixedly installed on the top of the loading platform 1. The transposition linear guide rails 4 are perpendicular to the test end 3. A plurality of evenly distributed transposition electric sliders 5 are driven and installed on the top of the transposition linear guide rails 4. A transposition frame 6 is fixedly installed on the top of the two transposition electric sliders 5 located at the same place. Figure 1 As shown, a same support plate 7 is fixedly mounted on the top of the multiple transposition racks 6, and two single-body loading assemblies are arranged on the top of the support plate 7;

[0042] The single loading assembly is used to load and transfer circuit boards loaded with chips, such as Figure 1 As shown, the monomer loading assembly includes a horizontally arranged linear guide rail 8 fixedly mounted on the top of the support plate 7, and the linear guide rail 8 is perpendicular to the transposition linear guide rail 4, as shown in FIG. Figure 6 As shown, the top drive of the traveling linear guide rail 8 is installed with a traveling electric slider 9, the top of the traveling electric slider 9 is fixedly installed with a support bracket 10, the top of the support bracket 10 is fixedly installed with a vertically arranged electric lifting slide 11, and the top of the driving end of the electric lifting slide 11 is fixedly installed with a vertically arranged center rod 12, as shown in FIG. Figure 7 As shown, a plurality of evenly distributed rotating collars 13 are rotatably sleeved on the center rod 12, and connecting rods 14 are fixedly mounted on the side walls of the rotating collars 13. Figure 8 As shown, a transfer insert 15 is fixedly installed at one end of the connecting rod 14, and the position of the transfer insert 15 corresponds to the position of the test end 3. A plurality of evenly distributed reset annular guide rails 16 are fixedly sleeved on the central rod 12, and the plurality of reset annular guide rails 16 are respectively located at the top of the plurality of rotating rings 13, as shown in FIG. Fig. 9 As shown, an annular return spring is arranged inside the return annular guide rail 16, and a return slide bar 17 is fixedly installed on the side wall of the rotating collar 13. The top end of the return slide bar 17 is slidably installed inside the return annular guide rail 16 and is fixedly connected to the annular return spring. In this embodiment, a stop baffle is arranged inside the return annular guide rail 16 to limit the maximum range of the circular sliding activity of the return slide bar 17, that is, to limit the steering range of the transport insert 15, so that the transport insert 15 can only rotate 180° at most;

[0043] The top of the support bracket 10 is provided with a steering assembly for pushing the reset annular guide rail 16 of a specified height to turn. Figure 5 As shown, the steering assembly includes a steering annular guide rail 18 fixedly mounted on the top of the support bracket 10, and the axial position of the steering annular guide rail 18 is consistent with the axial position of the center rod 12, as shown in FIG. Fig.11 As shown, a steering arc-shaped slider 19 is slidably installed inside the steering annular guide rail 18, and a bogie 20 is fixedly installed on the top of the steering arc-shaped slider 19. Fig.12As shown, a steering lever 21 is fixedly installed on one side of the top of the bogie 20, and the position of the steering lever 21 corresponds to the position of the transfer insert 15. A two-way air pump assembly 22 is fixedly installed on one side of the electric lifting slide 11. The same three-way air delivery pipe 23 is fixedly installed on the air delivery end and the air outlet end of the two-way air pump assembly 22. In this embodiment, the two-way air pump assembly 22 includes an air pump and an air extraction pump. The air delivery end of the air pump and the air inlet end of the air extraction pump are respectively connected to the two ends of the three-way air delivery pipe 23 through a control valve. An arc-shaped folded air bag 24 is arranged inside the steering annular guide rail 18. The top of the three-way air delivery pipe 23 is connected to the inside of the arc-shaped folded air bag 24. The steering arc slider 19 is fixedly connected to one end of the arc-shaped folded air bag 24. Specifically, when the chip loading device of the chip testing equipment body 2 is in use, the staff or the robot arm first inserts a circuit board loaded with chips into the transfer plug 15 of one of the single loading components, and exposes the part of the circuit board loaded with chips to the outside of the transfer plug 15, and then the electric lifting slide 11 drives the central rod 12 to carry each transfer plug 15 to move up a unit distance, so that the second transfer plug 15 rises to the position where the first transfer plug 15 was previously located, and then the second circuit board is inserted into the second transfer plug 15, until multiple circuit boards are inserted into each transfer plug 15 in turn. At this time, the traveling electric slider 9 carries multiple circuit boards and moves a certain distance along the traveling linear guide rail 8, and then the transposition electric slider 5 is moved by the transposition electric slider 5. The rack 6 and the support plate 7 carry two monomer loading assemblies and move laterally along the transposition linear guide rail 4, so that the first monomer loading assembly fully loaded with circuit boards moves to the front of the test end 3. At this time, the two-way air pump assembly 22 on the monomer loading assembly begins to inflate the arc-shaped folded airbag 24, so that the arc-shaped folded airbag 24 unfolds and extends inside the steering annular guide rail 18, thereby pushing the steering arc-shaped slider 19 to slide circumferentially along the steering annular guide rail 18, and then pushing the lowest transfer plug 15 through the steering rack 20 and the steering lever 21, so that it rotates 180° along the center rod 12 through the connecting rod 14 and the rotating ring 13, so that the opening of the transfer plug 15, that is, the end of the circuit board exposed outside the transfer plug 15 faces the test end 3. At the same time, the traveling electric slider 9 carries the circuit board to the test end 3, so that the circuit board and the chip are plugged into the insulation tank 302, and the circuit board is connected to the terminals inside the insulation tank 302. The test equipment body 2 heats the circuit board and the chip inside the test end 3, and then tests the working stability of the chip under high temperature. After the current chip test is completed, the traveling electric slider 9 drives the transfer insert 15 to reset, and the two-way air pump assembly 22 performs air extraction, so that the steering arc slider 19 is reset under the traction of the arc folding airbag 24, and the limit on the transfer insert 15 is released. At the same time, the transfer insert 15 is reset under the elastic force of the annular reset spring inside the reset annular guide rail 16, and then the electric lifting slide 11 descends a unit distance, so that the upper transfer insert 15 descends.Thus, the second circuit board and the chip thereon can be tested, thereby completing the alternating automatic docking of multiple chips with the test end 3 in sequence, without manually inserting the circuit board directly into the test equipment body 2, and only manually or by a robotic arm can the multiple circuit boards be inserted into the transfer insert 15 in sequence, effectively avoiding the direct docking between the loading station and the test station, ensuring the safety of the loading operation, and improving the chip loading and supply efficiency through the batch automatic transportation and docking of the circuit board. By setting up two single-body loading components, when the first single-body loading component is transported and docked with the test equipment body 2, , the staff or the robot arm can load the circuit board on the second single loading assembly, that is, there are two loading stations. When the test of the first batch of chips is completed, the transposition electric slider 5 drives the pallet 7 to move along the transposition linear guide 4 again, so that the second single loading assembly moves to the location of the test equipment body 2 for transportation and docking. At this time, the staff or the robot arm can remove the first batch of circuit boards and start the next round of loading, so that the loading of the second batch of circuit boards can be completed before the test of the previous batch of chips is completed, eliminating the waiting time between the loading of the two batches of chips, and further improving the feeding efficiency. ,

[0044] like Figure 7 , Fig.10 As shown, a positioning block 25 is fixedly installed on one side of the transfer insert 15. Fig.12 As shown, a laser rangefinder 26 is fixedly installed on one side of the top end of the bogie 20, and the position of the positioning block 25 corresponds to the position of the laser rangefinder 26; specifically, by setting the positioning block 25, after the electric lifting slide 11 drives multiple transfer inserts 15 to rise or fall collectively, the steering lever 21 is always located at the tail end of one of the transfer inserts 15. At this time, the laser rangefinder 26 on one side of the top end of the bogie 20 will measure the distance of the positioning block 25 on one side of the transfer insert 15, thereby realizing laser positioning, and preventing the transfer insert 15 from being misplaced due to the inadequate lifting action of the electric lifting slide 11, thereby affecting the loading, transportation, and docking processes of the circuit board and the chip.

[0045] like Fig.10 As shown, the side walls of the positioning block 25 are provided with limited insertion holes 2501, such as Figure 1 As shown, two limit frames 27 are fixedly installed on the top of the loading platform 1. Figure 4As shown, a horizontally arranged limit rod 28 is fixedly installed on the top of the limit frame 27, and the limit rod 28 is adapted to the limit socket 2501, and the limit rod 28 and the laser rangefinder 26 are located at the same height; specifically, by setting the limit rod 28, in the process of the robot arm loading the circuit board, the current loading monomer loading component will be directly in front of the limit frame 27, and after the laser rangefinder 26 laser positioning, the traveling electric slider 9 carries multiple transfer inserts 15 and moves a certain distance toward the position of the limit frame 27 until the limit rod 28 at one end of the limit frame 27 is inserted into the limit socket 2501 on one side of the current transfer insert 15, thereby locking the transfer insert 15 to prevent the transfer insert 15 from being offset due to the vibration generated during the insertion of the circuit board into the transfer insert 15, thereby affecting the accuracy of subsequent processes.

[0046] like Figure 4 As shown, a trapezoidal guide plate 29 is fixedly installed on one side of the top of the limit frame 27. The position of the trapezoidal guide plate 29 corresponds to the position of the transfer insert 15. In the present embodiment, the small opening of the trapezoidal guide plate 29 faces the transfer insert 15, and the large opening faces away from the transfer insert 15. Specifically, by setting the trapezoidal guide plate 29, when the limit rod 28 is inserted into the limit hole 2501, the trapezoidal guide plate 29 will dock with the opening of the transfer insert 15. At this time, the staff or the robot arm can insert the circuit board into the transfer insert 15 through the trapezoidal guide plate 29. The trapezoidal guide plate 29 with a trapezoidal structure can play a guiding role, so that the circuit board entering the trapezoidal guide plate 29 will be automatically inserted into the transfer insert 15, thereby reducing the time spent on the mutual positioning of the circuit board and the transfer insert 15, and improving the loading speed.

[0047] like Fig.10 As shown, an elastic rubber sleeve 30 is fixedly installed inside the transfer insert 15; specifically, by providing the elastic rubber sleeve 30, when the circuit board is inserted into the transfer insert 15, the elastic rubber sleeve 30 will be squeezed, causing the elastic rubber sleeve 30 to produce elastic deformation, thereby applying reverse pressure to the circuit board, so that the circuit board can be stably inserted into the transfer insert 15 and will not fall off due to the centrifugal force of the transfer insert 15 turning.

[0048] like Fig.10 As shown, a sealing rubber pad 31 is fixedly installed on the side wall of the opening of the transfer insert 15, and the sealing rubber pad 31 is adapted to the test interface 301; specifically, by setting the sealing rubber pad 31, when the transfer insert 15 is docked with the test end 3, the sealing rubber pad 31 will be stuck in the test interface 301, playing a role of sealing and heat insulation, thereby reducing the loss of heat inside the insulation tank 302 during the test process.

[0049] like Fig.12As shown, a linkage magnetic plate 32 is fixedly installed on the side wall of the steering lever 21, and the position of the linkage magnetic plate 32 corresponds to the position of the transfer insert 15. In the present embodiment, the linkage magnetic plate 32 is fixedly installed on the side wall of the steering lever 21 through an embedded structure, and the transfer insert 15 is made of a heat-insulating composite material. A magnetic metal plate is inlaid inside the tail end of the transfer insert 15 for being adsorbed by the linkage magnetic plate 32. Specifically, by setting the linkage magnetic plate 32, the linkage magnetic plate 32 can utilize the magnetic force to keep the steering lever 21 and the current transfer insert 15 in an adsorbed state. When the steering lever 21 is reset, the elastic force of the annular reset spring can be used to drive the transfer insert 15 to reset, thereby ensuring that the reset action of the transfer insert 15 is executed in place.

[0050] like Figure 7 , Figure 8 As shown, a C-shaped positioning frame 33 is provided on one side of the center rod 12, and the two ends of the C-shaped positioning frame 33 are respectively fixedly installed on the top and bottom ends of the center rod 12, and a plurality of evenly distributed fork frames 34 are fixedly installed on the C-shaped positioning frame 33, and a positioning magnetic block 35 is fixedly installed at one end of the fork frame 34. The positions of the plurality of positioning magnetic blocks 35 respectively correspond to the positions of the plurality of connecting rods 14. In the present embodiment, the connecting rods 14 are made of magnetic metal; specifically, by providing the positioning magnetic blocks 35, during the feeding process of the transfer insert 15, each connecting rod 14 will be adsorbed with the positioning magnetic blocks 35, and the elastic force of the annular reset spring will keep each transfer insert 15 in a limited state, thereby preventing the transfer insert 15 from being offset due to the vibration during the feeding process, thereby affecting the positioning accuracy.

[0051] In summary: when the chip testing equipment body 2 is in use with the chip loading device, the staff or the robot arm first inserts a circuit board loaded with chips into the transfer plug 15 of one of the single loading components, and exposes the part of the circuit board loaded with chips to the outside of the transfer plug 15, and then the electric lifting slide 11 drives the central rod 12 to carry each transfer plug 15 to move up a unit distance, so that the second transfer plug 15 rises to the position where the first transfer plug 15 was previously located, and then the second circuit board is inserted into the second transfer plug 15, until multiple circuit boards are inserted into each transfer plug 15 in turn. At this time, the traveling electric slider 9 carries multiple circuit boards and moves a certain distance along the traveling linear guide rail 8, and then the transposition electric slider 5 is transposed. The frame 6 and the support plate 7 carry two monomer loading assemblies and move laterally along the transposition linear guide rail 4, so that the first monomer loading assembly fully loaded with circuit boards moves to the front of the test end 3. At this time, the two-way air pump assembly 22 on the monomer loading assembly begins to inflate the arc-shaped folded airbag 24, so that the arc-shaped folded airbag 24 unfolds and extends inside the steering annular guide rail 18, thereby pushing the steering arc-shaped slider 19 to slide circumferentially along the steering annular guide rail 18, and then pushing the lowest transfer insert 15 through the steering frame 20 and the steering lever 21, so that it rotates 180° along the center rod 12 through the connecting rod 14 and the rotating ring 13, so that the opening of the transfer insert 15, that is, the end of the circuit board exposed outside the transfer insert 15 faces the test end 3. At the same time, the traveling electric slider 9 carries the circuit board to the test end 3, so that the circuit board and the chip are plugged into the insulation tank 302, and the circuit board is connected to the terminals inside the insulation tank 302. The test equipment body 2 heats the circuit board and the chip inside the test end 3, and then tests the working stability of the chip under high temperature. After the current chip test is completed, the traveling electric slider 9 drives the transfer insert 15 to reset, and the two-way air pump assembly 22 performs air extraction, so that the steering arc slider 19 is reset under the traction of the arc folding airbag 24, and the limit on the transfer insert 15 is released. At the same time, the transfer insert 15 is reset under the elastic force of the annular reset spring inside the reset annular guide rail 16, and then the electric lifting slide 11 descends a unit distance, so that the upper transfer insert 15 descends , so that the second circuit board and the chip thereon can be tested, thereby completing the alternating automatic docking of multiple chips with the test end 3 in sequence, without manually inserting the circuit board directly into the test equipment body 2, and only manually or by a robotic arm can insert multiple circuit boards into the transfer insert 15 in sequence, effectively avoiding the direct docking between the loading station and the test station, ensuring the safety of the loading operation, and improving the chip loading and supply efficiency through the batch automatic transportation and docking of the circuit board. By setting two single-body loading components, when the first single-body loading component is transported and docked with the test equipment body 2, the staff or the robotic arm can load the circuit board on the second single-body loading component, that is, there are two loading stations. When the test of the first batch of chips is completed,The transposition electric slider 5 drives the support plate 7 to move along the transposition linear guide rail 4 again, so that the second single loading assembly moves to the position of the test equipment body 2 for transfer and docking. At this time, the staff or the robot arm can remove the first batch of circuit boards and start the next round of loading, so that the loading of the second batch of circuit boards can be completed before the test of the previous batch of chips is completed, eliminating the waiting time between the loading of the two batches of chips, and further improving the feeding efficiency. By setting the positioning block 25, after the electric lifting slide 11 drives multiple transfer inserts 15 to rise or fall collectively, the steering lever 21 is always located at the tail end of one of the transfer inserts 15. At this time, the laser rangefinder 26 on the top side of the bogie 20 will position the positioning block 25 on one side of the transfer insert 15 The distance measurement is carried out to realize laser positioning, so as to prevent the transfer insert 15 from being misplaced due to the inadequate lifting action of the electric lifting slide 11, thereby affecting the loading, transportation and docking processes of the circuit board and the chip. By setting the limit rod 28, during the process of the robot arm loading the circuit board, the current single loading component will be directly in front of the limit frame 27. After the laser rangefinder 26 performs laser positioning, the moving electric slider 9 carries multiple transfer inserts 15 and moves a certain distance toward the position of the limit frame 27 until the limit rod 28 at one end of the limit frame 27 is inserted into the limit hole 2501 on one side of the current transfer insert 15, thereby locking the transfer insert 15 to prevent the vibration caused by the insertion of the circuit board into the transfer insert 15. The transfer insert 15 is caused to be positionally offset, which affects the accuracy of subsequent processes. By setting a trapezoidal guide plate 29, when the limiting plug rod 28 is inserted into the limiting plug hole 2501, the trapezoidal guide plate 29 will dock with the opening of the transfer insert 15. At this time, the staff or the robot arm can insert the circuit board into the transfer insert 15 through the trapezoidal guide plate 29. The trapezoidal guide plate 29 with a trapezoidal structure can play a guiding role, so that the circuit board entering the trapezoidal guide plate 29 will be automatically inserted into the transfer insert 15, thereby reducing the time spent on the mutual positioning of the circuit board and the transfer insert 15 and improving the loading speed. By setting an elastic rubber sleeve 30, when the circuit board is inserted into the transfer insert 15, it will squeeze the elastic rubber sleeve 30, causing the elastic rubber sleeve 30 to produce The elastic deformation exerts reverse pressure on the circuit board, so that the circuit board can be stably inserted in the transfer plug 15 and will not fall off due to the centrifugal force of the transfer plug 15 turning. By setting the sealing rubber pad 31, when the transfer plug 15 is docked with the test end 3, the sealing rubber pad 31 will be stuck in the test interface 301, which plays a role of sealing and heat insulation, and reduces the heat loss inside the insulation tank 302 during the test. By setting the linkage magnetic suction plate 32, the linkage magnetic suction plate 32 can use the magnetic suction force to keep the steering lever 21 and the current transfer plug 15 in an adsorption state. When the steering lever 21 is reset, the elastic force of the annular reset spring can be used to drive the transfer plug 15 to reset, ensuring that the reset action of the transfer plug 15 is executed in place. By setting the positioning magnetic suction block 35,During the loading process of the transfer insert 15, each connecting rod 14 will be attracted to the positioning magnetic block 35, and the elastic force of the annular return spring will keep each transfer insert 15 in a limited position, thereby preventing the transfer insert 15 from being offset due to vibration during the loading process, thereby affecting the positioning accuracy.
