Description

Technical Field

[0001] The invention relates to the technical field of tray stack strength testing, in particular to a chip tray stack strength testing device. Background Art

[0002] Electronic chip trays are packaging trays used by semiconductor packaging and testing companies for chip packaging and testing. The trays used on electronic products include stamping-type trays and blister-formed trays. Many trays are used to prevent static electricity from touching the products, which plays a good protective role. The trays also play a role in transportation and carrying. A chip tray stack refers to a combination of multiple chip trays stacked together in a certain way. Stacking them can store more chip trays in a limited space and improve storage efficiency. At the same time, it is also convenient for batch processing of chips in production and transportation. In order to ensure the safety of the tray when carrying and transporting chips, it is necessary to conduct strength tests on the tray stack to avoid damage to the chips when the tray stack is insufficiently strong and affected by external forces;

[0003] Compression test is the most common strength test for chip tray stacks and can directly reflect the load-bearing and compressive strength of chip tray stacks. Existing presses can usually only perform pressure tests on a fixed number of tray stacks and it is difficult to perform pressure tests on different numbers of tray stacks. Therefore, we propose a chip tray stack strength test device. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a chip tray stack strength testing device, comprising:

[0005] A pressure machine body, wherein a lower pressure plate is arranged on the top of the pressure machine body;

[0006] A concave frame, wherein both sides of the inner wall of the concave frame are provided with electric push rods;

[0007] A hydraulic push rod, wherein a square pressure block is arranged at the bottom of the hydraulic push rod;

[0008] A pre-pressing device, which is used to elastically pre-press different numbers of chip tray stacks;

[0009] A dust cleaning device, which blows out the dust between the trays by blowing air;

[0010] The top of the pressure body is fixedly connected to the bottom of the lower pressing plate, and the top of the pressure body is fixedly connected to the bottom of the concave frame. The inner wall of the concave frame is fixedly connected to one end of the electric push rod, and the driving shaft of the electric push rod is fixedly connected to one side of the dust cleaning device. The side of the dust cleaning device away from the electric push rod is fixedly connected to one side of the pre-pressing device. The top of the inner wall of the concave frame is fixedly connected to the top of the hydraulic push rod, and the bottom of the hydraulic push rod is fixedly connected to the top of the square pressing block;

[0011] Among them, the pre-pressing device includes:

[0012] A concave frame plate, and a driving mechanism is arranged at the top of the concave frame plate;

[0013] An internal pressing plate, which is used to pre-press different numbers of stacked chip trays. By adjusting the height of the internal pressing plate in the concave frame plate through the driving mechanism, different numbers of stacked chip trays can be pre-pressed, preventing the existing press from usually only being able to perform pressure tests on a fixed number of stacked trays and being difficult to perform pressure tests on different numbers of stacked trays;

[0014] One end of the driving mechanism penetrates through the concave frame plate and is threadedly connected to the concave frame plate. The bottom of the driving mechanism is rotationally connected to the top of the internal pressing plate through a rotating bolt;

[0015] One side of the concave frame plate is fixedly connected to one side of the dust cleaning device;

[0016] A rectangular rubber pad is fixedly connected to the bottom of the internal pressing plate. By pushing the rectangular rubber pad at the bottom with the internal pressing plate, the parts near the two sides of the top of the stacked chip trays are pre-pressed and fixed, preventing the stacked chip trays from not being placed stably and one side from tilting up, which affects the subsequent pressure test effect. By arranging an elastic and squeezable rectangular rubber pad at the bottom of the internal pressing plate to make elastic contact pre-pressing with the stacked chip trays, it is prevented that when the hard material internal pressing plate pre-presses the stacked chip trays, it is difficult to control the pressure, resulting in too large or too small pressure and affecting the pressure test effect. A long baffle is fixedly connected to the top of the internal pressing plate. When the long baffle moves down together with the internal pressing plate, it blocks and seals the exhaust holes above the internal pressing plate in the dust cleaning device, preventing the area that does not need to be blown with dust above the internal pressing plate from still exhausting air and affecting the blowing efficiency below. A cleaning mechanism is arranged at the bottom of the inner wall of the concave frame plate;

[0017] There are multiple long baffles, and the multiple long baffles are distributed on the internal pressing plate. The top of the cleaning mechanism is fixedly connected to the bottom of the dust cleaning device.

[0018] Furthermore, the driving mechanism includes a first corrugated ring and a second corrugated ring. By sleeving the first corrugated ring and the second corrugated ring outside the thin through rod, the outside of the threaded long rod is covered for dust prevention, preventing the flying dust blown by the dust cleaning device from adhering to the thread surface of the threaded long rod and affecting the thread fit with the concave frame plate. A top circular block is fixedly connected to the top of the second corrugated ring, and a motor is fixedly connected to the top of the top circular block. The driving shaft of the motor is fixedly connected to the threaded long rod, and a thin through rod is fixedly connected to the bottom of the top circular block. By arranging the thin through rod between the threaded long rod and the first corrugated ring and the second corrugated ring for resistance and isolation, it is prevented that the first corrugated ring and the second corrugated ring fold inward and squeeze against the thread surface of the threaded long rod during waveform contraction, affecting the thread fit of the threaded long rod. The bottom of the first corrugated ring is fixedly connected to the top of the built-in pressing plate, the top of the first corrugated ring is fixedly connected to the inner wall of the concave frame plate, the bottom of the second corrugated ring is fixedly connected to the top of the concave frame plate, the top of the threaded long rod is rotatably connected to the bottom of the top circular block through a rotating bolt, the bottom of the thin through rod penetrates through the concave frame plate and is fixedly connected to the top of the built-in pressing plate, and a plurality of thin through rods are provided, and the plurality of thin through rods are distributed between the threaded long rod and the second corrugated ring.

[0019] Furthermore, the cleaning mechanism includes an electric slide rail, and an arc-shaped connecting rod is slidably connected to the inner wall of the electric slide rail. A V-shaped scraper is fixedly connected to one end of the arc-shaped connecting rod away from the electric slide rail. When the V-shaped scraper moves, it scrapes the bottom surface of the rectangular rubber pad to prevent dust particles and impurities from adhering to the bottom surface of the rectangular rubber pad after long-term use, affecting the subsequent use effect. A rigid brush is fixedly connected to the outside of the V-shaped scraper. When the rigid brush moves with the V-shaped scraper, it peels and cleans the bottom surface of the rectangular rubber pad to prevent a part of the dust particles and impurities on the bottom surface of the rectangular rubber pad from being embedded in the bottom surface and being difficult to be effectively cleaned by scraping. The top of the electric slide rail is fixedly connected to the bottom of the dust cleaning device, and two arc-shaped connecting rods are provided, and the two arc-shaped connecting rods are distributed on the inner wall of the electric slide rail.

[0020] Furthermore, the dust cleaning device includes a ventilation plate. An exhaust round hole is provided on one side of the ventilation plate. By arranging a plurality of exhaust round holes on one side of the ventilation plate, dust blowing treatment is carried out between the trays of the chip tray stack, preventing excessive dust from being mixed between the chip tray stacks that need to be pressure - tested, which may increase wear and affect the test effect when being squeezed and deformed. The side of the ventilation plate away from the exhaust round hole is communicated with a high - pressure air pump. A square sleeve plate is sleeved and fixedly connected to the outside of the high - pressure air pump. A fixing block is fixedly connected to the side of the square sleeve plate close to the ventilation plate. By fixedly sleeving the square sleeve plate outside the high - pressure air pump and fixing it to the ventilation plate through the fixing block, the stability of the high - pressure air pump is ensured, preventing the high - pressure air pumps arranged on one side of the ventilation plate from being easily disconnected from the ventilation plate due to vibration force after long - term use. A shock - absorbing spring is fixedly connected to the side of the square sleeve plate close to the ventilation plate. By arranging a plurality of shock - absorbing springs between the ventilation plate and the square sleeve plate, shock - absorbing treatment is carried out on the high - pressure air pumps working at high frequency, preventing the strong vibration force generated when the plurality of high - pressure air pumps work from causing the chip tray stack to shake and affect the pressure test effect. An internal connecting rod is fixedly connected to the side of the inner wall of the ventilation plate close to the high - pressure air pump. One end of the internal connecting rod is fixedly connected to a circular baffle. By arranging a circular baffle in the ventilation plate that is aligned with the air outlet of the high - pressure air pump, the inflowing gas is blocked, preventing the gas filled into the ventilation plate by the high - pressure air pump from directly spraying out from the local exhaust round holes in the front and making it difficult to spray out evenly from each exhaust round hole. The ventilation plate is set as a rectangular shell with a cavity inside. One side of the ventilation plate is fixedly connected to the driving shaft of the electric push rod.

After the chip tray stack is placed on the lower pressure plate 2, the electric push rod 4 pushes the dust cleaning device 8 to drive the concave frame plate 701 on one side to perform side pressure limiting on the chip tray stack. At the same time, the driving mechanism 702 drives the built-in pressure plate 703 to move downward to pre-press the chip tray stack.

When the threaded long rod 7025 rotates, it cooperates with the thread of the concave frame plate 701 to rotate downward. When the threaded long rod 7025 moves downward, it drives the built-in pressure plate 703 at the bottom to move downward. When the threaded long rod 7025 moves downward, it drives the thin penetration rod 7026 to move downward together through the top round block 7023, and compresses the second corrugated ring piece 7022, pulling the first corrugated ring piece 7021 The outer side of the threaded long rod 7025 is wrapped and covered for dust prevention by sleeve-arranging the first corrugated ring piece 7021 and the second corrugated ring piece 7022 on the outer side of the thin penetration rod 7026, and the thin penetration rod 7026 is arranged between the threaded long rod 7025 and the first corrugated ring piece 7021 and the second corrugated ring piece 7022 for resistance and isolation. When the built-in pressing plate 703 is driven by the threaded long rod 7025 to move down to the bottom surface and contact the top of the V-shaped scraper 7063, the arc connecting rod 7062 is driven by the electric slide rail 7061 to drive the V-shaped scraper 7063 to move. When the V-shaped scraper 7063 moves, the bottom surface of the rectangular rubber pad 704 is scraped and cleaned. When the V-shaped scraper 7063 moves, it drives the hard brush 7064 on the outer side to move together.When the rigid brush 7064 moves along with the V-shaped scraper 7063, it peels and cleans the bottom surface of the rectangular rubber pad 704. After the rectangular rubber pad 704 pre-presses the chip tray stack through the built-in pressing plate 703, gas is filled into the ventilation plate 801 by the high-pressure air pump 803. The gas enters the interior of the ventilation plate 801, contacts the circular baffle 808, is blocked by the circular baffle 808, and diffuses around the circular baffle 808 to various parts inside the ventilation plate 801. When the interior of the ventilation plate 801 is filled with gas, it will be discharged to the outside through the exhaust round holes 802. By arranging a plurality of exhaust round holes 802 on one side of the ventilation plate 801, dust blowing treatment is carried out between the trays of the chip tray stack. By arranging a circular baffle 808 inside the ventilation plate 801 that is aligned with the air outlet of the high-pressure air pump 803, the filled gas is blocked. By fixedly sleeving a square sleeve plate 804 outside the high-pressure air pump 803 and fixedly connecting it to the ventilation plate 801 through a fixing block 805, the stability of the high-pressure air pump 803 is ensured. By arranging a plurality of shock-absorbing springs 806 between the ventilation plate 801 and the square sleeve plate 804, shock-absorbing treatment is carried out on the high-pressure air pump 803 operating at high frequency.,
