Description

Technical Field

[0001] The present invention relates to the field of memory cards, and particularly to a memory card metal sheet contact detection device. Background Art

[0002] A memory card is an independent storage medium used in mobile phones, digital cameras, portable computers, MP3 players, and other digital products. It is generally in the form of a card and is also known as a "digital memory card", "digital storage card", "memory card", etc.

[0003] Currently, memory cards need to be tested during factory production to detect whether there is poor contact during use. The entire testing process is achieved by testing equipment. However, during the current testing process, generally, the memory card is first clamped by a fixture and then pushed into the detection socket for testing. Due to many factors affecting the testing process, there may be a situation of testing errors. Therefore, it is generally necessary to insert and remove the card several times to confirm whether it is effective. Since the memory card is relatively thin, the traditional clamping structure is likely to damage the memory card. After inserting the memory card, if it needs to be tested again, the memory card needs to be pulled out. The method of inserting and removing the memory card using the fixture will obviously increase the probability of the fixture damaging the memory card.

[0004] In addition, due to the influence of the external environment, any dust may fall on the metal sheet of the memory card exposed to the air, and these dusts will also affect the accuracy of the test results. Therefore, when there is a testing problem, a cleaning operation is often required, which leads to a more complex overall structure and a significant reduction in the efficiency of the entire testing process. Summary of the Invention

[0005] The technical problem to be solved by the present invention is a memory card metal sheet contact detection device, which uses a structure of a negative pressure driving wheel. It can not only complete the guiding of the memory card, but also realize the pulling-out action of the memory card. Moreover, when the memory card passes through the negative pressure driving wheel, it can also suck the dust and foreign matters on the metal sheet, improving the testing accuracy. At the same time, this structure adopts an integrated driving structure without additional structures, and the design is more reasonable.

[0006] The present invention is realized through the following technical solutions: A memory card metal sheet contact detection device includes a detection table and a control console. The control console is arranged on one side of the detection table. On both sides of the upper end surface of the detection table, a support table is provided respectively. An installation cavity is opened on the opposite surface of the support table. A cross push rod is arranged on the upper end surface of the detection table between the two installation cavities. An ejecting airbag is arranged in each of the installation cavities. One side of the ejecting airbag is in contact with the bottom surface of the installation cavity, and the other side is in contact with and supports the cross push rod.

[0007] One or more guiding brackets are arranged side by side on the upper end surface of the inspection table near the control console. The storage cards to be inspected are arranged in the guiding brackets, and one end of each storage card is supported by a horizontal push rod in contact. One or more inspection sockets are arranged on the side of the guiding bracket away from the horizontal push rod. Each inspection socket corresponds to a guiding bracket. The storage card is pushed by the horizontal push rod, and the metal sheet of the storage card is inserted into the inspection socket. The output end of each inspection socket is connected to the control host on the control console through a control signal line. A display screen is also arranged on the control console, and the detected values are displayed on the display screen;

[0008] One or more negative pressure driving wheels are arranged at the bottom of each guiding bracket. An air delivery pump is arranged on one side of the inspection table. All the negative pressure driving wheels are connected and communicated through a gas duct. One end of the gas duct is connected to the input end of the air delivery pump, and the output end of the air delivery pump is connected to the ejecting air bags in two installation cavities. Negative pressure suction holes are arranged on each negative pressure driving wheel.

[0009] As a preferred technical solution, the inside of the negative pressure driving wheel is hollow to form a negative pressure cavity. Each negative pressure suction hole communicates with the negative pressure cavity. The two sides of the negative pressure driving wheel are respectively rotatably inserted into the gas duct. Sealing convex parts are arranged at the assembly ends of the gas duct and the negative pressure driving wheel. One shaft hole is arranged on each side of the negative pressure driving wheel, and the sealing convex part is rotatably installed in the shaft hole.

[0010] As a preferred technical solution, a plurality of annular grooves are formed on the inner wall surface of the shaft hole. Sealing convex rings are arranged at the positions corresponding to the annular grooves on the outer wall surface of the sealing convex part, and the sealing convex rings are movably buckled into the annular grooves.

[0011] As a preferred technical solution, torsion springs are fixedly installed on the outer side ends of the sealing convex parts near the gas duct. The outer side ends of the sealing convex parts are elastically connected to the hollow negative pressure driving wheels through the torsion springs.

[0012] As a preferred technical solution, a plurality of contact convex rings are arranged around the outer wall surface of the negative pressure driving wheel. The contact convex rings are all made of rubber materials, and anti-slip textures are arranged on the contact convex ring surfaces.

[0013] As a preferred technical solution, each guiding bracket includes two side plates and a top plate arranged between the two side plates, and the gas duct is connected from the two side plates.

[0014] As a preferred technical solution, one guiding roller is arranged on each side of the horizontal push rod. The horizontal push rod is in rolling contact with the bottom surface of the installation cavity through the guiding rollers. Two L-shaped brackets are arranged at the positions of the horizontal push rod in the installation cavity. One side of one L-shaped bracket is in contact with the ejecting air bag, and a spring is arranged on one side of the other L-shaped bracket, and the other end of the spring is in contact with the bottom surface of the installation cavity.

[0016] As a preferred technical solution, air leakage holes are also arranged on the ejecting airbag.

[0017] The beneficial effects of the present invention are as follows: First, since the present invention does not provide an included angle, even if the card is inserted and removed multiple times, the fixture will not damage the storage card, which improves the safety of the insertion and removal detection and reduces the scrap rate of the storage card;

[0018] Second, during the process of inserting and removing the storage card, the action of removing the storage card is realized based on the negative pressure driving wheel. When the storage card is inserted, the negative pressure driving wheel elastically twists. When the insertion action is completed and the detection is completed, at this time, only the gas transmission pump needs to be closed, and the storage card can be removed by using the reset negative pressure driving wheel. In this way, the entire process does not require the use of a fixture to complete the insertion and removal, which is safer;

[0019] Third, the negative pressure used by the negative pressure driving wheel of the present invention comes from the gas transmission pump. The gas transmission pump is used to fill the ejecting airbag with gas, so that a negative pressure is generated at the position of the negative pressure driving wheel. In this way, the dust on the metal sheet of the storage card can be sucked by using the negative pressure suction force, achieving the purpose of dust removal and increasing the detection stability.

[0027] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically recited, may be replaced by other equivalent or alternative features with similar purposes. That is, unless specifically recited, each feature is only an example of a series of equivalent or similar features.

[0028] As Figure 1 and Figure 4 shown, a storage card metal sheet contact detection device of the present invention includes a detection table 1 and a control console 5. The control console 5 is arranged on one side of the detection table 1. On both sides of the upper end surface of the detection table 1, a support platform 31 is provided respectively. An installation cavity 32 is opened on the opposite surfaces of the support platform 31. A cross push rod 2 is arranged on the upper end surface of the detection table 1 between the two installation cavities 32. An ejection airbag 16 is arranged in each of the installation cavities 32. One side of the ejection airbag 16 is in contact with the bottom surface of the installation cavity 32, and the other side is in contact with and supports the cross push rod 2;

[0029] One or more guiding brackets 9 are arranged side by side on the upper end surface of the detection table 1 close to the control console 5. The storage cards 18 to be detected are arranged in the guiding brackets 9. One end of each storage card is supported by the cross push rod 2. One or more detection sockets 4 are arranged on the side of the guiding brackets 9 away from the cross push rod 2. Each detection socket 4 corresponds to one guiding bracket 9. The storage card 18 is pushed by the cross push rod 2 and the metal sheet of the storage card 18 is inserted into the detection socket 4. The output end of each detection socket 4 is connected to the control host 7 on the control console 5 through a control signal line. A display screen 6 is also arranged on the control console 5, and the detected values are displayed on the display screen 6;

[0030] One or more negative pressure driving wheels 21 are arranged at the bottom of each guiding bracket 9. An air delivery pump 13 is arranged on one side of the detection table. The negative pressure driving wheels 21 are connected and communicated with each other through an air duct 17. One end of the air duct 17 is connected to the input end of the air delivery pump 13, and the output end of the air delivery pump 13 is connected to the ejection airbags 16 in the two installation cavities. Negative pressure suction holes 22 are arranged on each of the negative pressure driving wheels 21.

[0031] As Figure 4 shown, the inside of the negative pressure driving wheel 21 is hollow and forms a negative pressure cavity. Each negative pressure suction hole communicates with the negative pressure cavity. The two sides of the negative pressure driving wheel are respectively rotatably inserted into the air duct 17. Sealing convex parts 24 are arranged at the assembly ends of the air duct 17 and the negative pressure driving wheel 21. Shaft holes are arranged on both sides of the negative pressure driving wheel 21. The sealing convex parts are rotatably installed in the shaft holes. As Figure 5 shown.

[0032] Among them, a plurality of annular grooves are formed on the inner wall surface of the shaft hole. Sealing convex rings 25 are arranged at the positions of the outer wall surface of the sealing convex part 24 corresponding to the annular grooves. The sealing convex rings 25 are movably buckled into the annular grooves. As Figure 5The assembly structure of the sealing convex ring and the annular groove shown enables the negative pressure driving wheel 21 to rotate in a sealed manner with the guide tube, which can achieve sealed rotation while ensuring airtightness and can complete rotation. The airtightness does not need to be very high, and the negative pressure suction can be used to adsorb dust.

[0033] Among them, torsion springs 23 are fixedly installed on the outer sides of the outer ends of the sealing convex parts 24 near the air guide tube. The outer ends of the sealing convex parts 24 are elastically connected to the hollow negative pressure driving wheel through the torsion springs. When the cross push rod drives displacement by ejecting the air bag, the cross push rod can be used to push each storage card into the detection socket. As Figure 2 shown, during the process of the cross push rod pushing, since the air pump has been inputting gas into the ejecting air bag, and the air inlet end of the air pump is connected to the air guide tube, negative pressure will be generated at the positions of the negative pressure suction holes of each negative pressure guide wheel. At this time, when the storage card passes through the negative pressure guide wheel, the dust on the metal sheet can be adsorbed by using the negative pressure, which increases the detection accuracy. After the storage card is pushed in by the negative pressure guide wheel, the torsion spring will elastically twist. When the air pump stops supplying gas, the negative pressure guide wheel elastically resets. Since the bottom of the negative pressure guide wheel rolls on the upper end surface of the storage card, the reset negative pressure guide wheel can push the storage card in the reverse direction, and the pulling out action of the storage card relative to the detection socket can be completed. The whole process does not require a clamping structure, which is safer and the plugging and unplugging actions are more convenient.

[0034] In this embodiment, a plurality of contact convex rings are arranged around the outer wall surface of the negative pressure driving wheel in a circle. The contact convex rings are all made of rubber materials, and anti-slip textures are arranged on the surfaces of the contact convex rings.

[0035] As Figure 3 shown, the guide bracket 9 includes two side plates and a top plate 91 arranged between the two side plates 92. The air guide tube is connected from both sides of the side plates.

[0036] Two guide rollers 3 are arranged on both sides of the cross push rod. The cross push rod is in rolling contact with the bottom surface of the installation cavity through the guide rollers 3. Two L-shaped brackets 14 are arranged at the positions of the cross push rod in the installation cavity. One side of one L-shaped bracket 14 is in contact with the ejecting air bag 16, and a spring 12 is arranged on one side of the other L-shaped bracket 14. The other end of the spring is in contact with the bottom surface of the installation cavity, and the cross push rod is reset by the spring.

[0037] Among them, the air pump 13 is controlled to be turned on or off by the control host. Control buttons are arranged on the control host 7. Leakage holes are also arranged on the ejecting air bag. When the air pump works, the leakage holes leak air, but since the air supply speed is greater than the air leakage speed, the ejecting air bag is in a continuous expanding state. When it is necessary to pull out the storage card after the detection is completed, at this time, only need to turn off the air pump, the leakage holes discharge the air inside the ejecting air bag, and the spring pushes the cross push rod to reset. Under the action of the torsion spring, the negative pressure guide wheel resets, achieving the purpose of pulling out the storage card.

[0038] The beneficial effects of the present invention are as follows: First, since there is no included angle in the present invention, even if the plugging and unplugging are performed multiple times, the fixture will not damage the storage card, which improves the safety of plugging and unplugging detection and reduces the scrap rate of the storage card;

[0039] Second, during the process of plugging and unplugging the storage card, the action of unplugging the storage card is realized based on the negative pressure driving wheel. When the storage card is inserted, the negative pressure driving wheel elastically twists. When the insertion action is completed and the detection is completed, only the air pump needs to be turned off at this time, and the storage card can be unplugged by using the reset negative pressure driving wheel. In this way, the entire process does not require the use of a fixture to complete the plugging and unplugging, which is safer;

[0040] Third, the negative pressure used by the negative pressure driving wheel of the present invention comes from the air pump. The air pump is used to fill the ejecting airbag with gas, so that a negative pressure is generated at the position of the negative pressure driving wheel. In this way, the dust on the metal sheet of the storage card can be sucked by the negative pressure suction to achieve the purpose of dust removal and improve the detection stability.

[0041] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative labor should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
