[0002] The electronic product sampling device consists of a conveying mechanism, a sampling mechanism and a detection area. When the product reaches the sampling position, the sampling controller triggers the movement of the robotic arm according to the preset sampling rules.

[0013] Preferably, a buffer plate is movably inserted into the rotating limiting plate.

[0014] A random inspection method in an electronic product production system comprises the following steps: S1: The electronic products are placed on the conveyor belt for transportation. According to the distance between the electronic products, the friction between the driving gear and the rack is used to drive the moving component to move on the guide rail. The spacing between the electronic products is the same, thus ensuring that the moving component can position the electronic products in time. S2: According to the width of the electronic product, adjust the distance between the two sets of rotating limit plates and adjust the angle of the rotating limit plates to ensure that the rotating limit plates can better limit and support the electronic products. At the same time, during the rotation of the rotating limit plates, the spherical shaft will rotate in the spherical shaft seat, thereby ensuring the support effect of the rotating limit plates during movement.

[0015] S3: According to the type of electronic product, the corresponding second electric push rod is controlled to work. When facing an electronic product with a flat upper surface, the second electric push rod on the exhaust pipe side is driven. When facing an electronic product with a flat side, the second electric push rod on the third electric push rod side is controlled. The electronic product is adsorbed on the upper and lower steam discs through the structure composed of the upper and lower steam discs, and the two clamping plates are brought close to each other to clamp the electronic product.

[0016] S4: The piston rod of the fourth electric push rod pushes the object receiving plate to move to the lower steam plate or below the positive and negative screw rods, and the clamped electronic product falls on the object receiving plate and slides in the groove body on the upper surface of the object receiving plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. According to the type of electronic product, the corresponding second electric push rod is controlled to work. When facing the electronic product with a flat upper surface, the second electric push rod on the exhaust pipe side is driven. When facing the electronic product with a flat side, the second electric push rod on the third electric push rod side is controlled. The electronic product is adsorbed on the upper and lower steam discs through the upper and lower steam discs. The two clamping plates are brought close to each other to achieve the clamping of the electronic product. The freely switchable clamping tool can be adjusted according to different shapes to ensure a close fit to the equipment. When the clamping tool can be freely switched according to the shape of the electronic product, it can better adapt to different pressure distribution requirements. Taking the clamping of electronic products with edges as an example, if the tool cannot adjust the shape, the clamping structure of the tool itself or the shell of the electronic product may be damaged due to excessive local pressure. The freely switchable clamping tool can evenly distribute the pressure on the appropriate contact surface, reducing the shortened life of the tool due to excessive wear or damage, thereby reducing the cost of frequent tool replacement for users.

[0018] 2. Electronic products are placed on the conveyor belt for transportation. According to the distance between the electronic products, the friction between the driving gear and the rack is used to drive the mobile component to move on the guide rail. The spacing between the electronic products is the same, thereby ensuring the timely positioning of the electronic products by the mobile component. During the production or use of different electronic products, the distance between them may vary due to various factors. By adjusting the position of the monitoring element according to the distance, the monitoring element can always be in the best detection position, and the relevant parameters of each electronic product can be accurately obtained.

[0019] 3. According to the width of the electronic product, adjust the distance between the two sets of rotating limit plates, and adjust the angle of the rotating limit plates to ensure that the rotating limit plates can better limit and support the electronic products. At the same time, during the rotation of the rotating limit plates, the spherical shaft will rotate in the spherical shaft seat to ensure the support effect during the movement of the rotating limit plates. The rotating limit plates can be adjusted to fit closely according to the width of the electronic product. When the electronic product is placed in the space surrounded by the two sets of limit plates, the limit plates can support and fix the product from both sides to prevent the product position from being offset.

[0020] 4. The piston rod of the fourth electric push rod pushes the receiving tray to move to the bottom of the lower steam plate or the positive and negative screw rods. The clamped electronic products fall on the receiving tray and slide in the groove on the upper surface of the receiving tray to ensure that the electronic products are on the inner wall side of the receiving tray, so that the staff can take the electronic products that need to be inspected conveniently. The use of a receiving tray with an inclined inner wall can enable the electronic products to move smoothly along a preset path. For some electronic products with precision components inside, such as hard disk drives or high-precision sensors, this guide can prevent internal components from malfunctioning due to impact, thereby reducing the damage rate of the product.

[0045] A buffer plate 42 is movably inserted in the rotating limiting plate 35 to ensure the limiting of the electronic product and prevent the electronic product from being damaged by pressure.

[0046] A random inspection method in an electronic product production system comprises the following steps: S1: The electronic products are placed on the conveyor belt 2 for conveying. According to the distance between the electronic products, the friction between the driving gear 24 and the rack 25 drives the moving assembly 23 to move on the guide rail 21. The spacing between the electronic products is the same, thereby ensuring that the moving assembly 23 positions the electronic products in time; S2: According to the width of the electronic product, adjust the distance between the two sets of rotating limit plates 35 and adjust the angle of the rotating limit plates 35 to ensure that the rotating limit plates 35 can better limit and support the electronic product. At the same time, during the rotation of the rotating limit plates 35, the spherical shaft 40 will rotate in the spherical shaft seat 41, thereby ensuring the support effect of the rotating limit plates 35 during movement.

[0047] S3: According to the type of electronic product, the corresponding second electric push rod 6 is controlled to work. When facing an electronic product with a flat upper surface, the second electric push rod 6 on the side of the exhaust pipe 9 is driven. When facing an electronic product with a flat side, the second electric push rod 6 on the side of the third electric push rod 16 is controlled. The electronic product is adsorbed on the upper steam plate 12 and the lower steam plate 13 through the structure composed of the upper steam plate 12 and the lower steam plate 13, and the two clamping plates 20 are brought close to each other to clamp the electronic product.

[0048] S4: The piston rod of the fourth electric push rod 28 pushes the object receiving plate 29 to move to the lower steam plate 13 or the positive and negative threaded rods 19, and the clamped electronic products fall on the object receiving plate 29 and slide in the groove body on the upper surface of the object receiving plate 29.

[0049] Working principle: The first step: electronic products are placed on the conveyor belt 2 for transportation. According to the distance between the electronic products, the position of the mobile component 23 on the guide rail 21 is adjusted. The output shaft of the mobile component 23 drives the driving gear 24 to rotate. The friction between the driving gear 24 and the rack 25 drives the mobile component 23 to move on the guide rail 21. At the same time, the limiting wheel 26 on the mobile component 23 can also limit the movement of the mobile component 23 to ensure the movement stability of the mobile component 23. The distance between the mobile component 23 and the gantry 3 is the same as the spacing between the electronic products, thereby ensuring that the mobile component 23 can position the electronic products in time.

[0050] The second step: according to the width of the electronic product, the distance between the two sets of rotating limit plates 35 is adjusted, and the circular rotating seat 33 is pushed to move by the piston rod of the fifth electric push rod 32. The movement of the circular rotating seat 33 drives the rotating limit plate 35 to move, thereby ensuring the limiting effect of the rotating limit plate 35 on the electronic product. When the piston rod of the fifth electric push rod 32 moves, it also drives the telescopic support rod 37 to move, and supports the movement of the rotating limit plate 35 to ensure the movement stability of the rotating limit plate 35. The piston rod of the sixth electric push rod 39 pushes the spherical shaft 40 and the spherical shaft seat 41 to move, thereby driving the two rotating limit plates 35 to rotate closer to each other, and adjusting the angle of the rotating limit plate 35 to ensure that the rotating limit plate 35 can better limit and support the electronic product. At the same time, during the rotation of the rotating limit plate 35, the spherical shaft 40 will rotate in the spherical shaft seat 41, thereby ensuring the support effect of the rotating limit plate 35 during the movement.

[0051] Step 3: According to the type of electronic product, the corresponding second electric push rod 6 is controlled to work. When facing the electronic product with a flat upper surface, the second electric push rod 6 on the side of the exhaust pipe 9 is driven. When facing the electronic product with a flat side, the second electric push rod 6 on the side of the third electric push rod 16 is controlled. The second electric push rod 6 drives the moving rod 7 to move on the rectangular installation frame 5. When the moving rod 7 moves on the rectangular installation frame 5, the moving rod 7 is limited by the cross bar 8 at the same time to ensure the stability of the movement of the moving rod 7. When the exhaust pipe 9 moves to the center position of the rectangular installation frame 5, the first electric push rod 4 pushes the rectangular installation frame 5. The air pump 10 transmits the suction force to the exhaust pipe 9 through the gas delivery pipe 11, and the air flow entering the upper steam plate 12 enters the upper steam plate 12 and the lower steam plate 13 through the gas discharge valve 15, so that the electronic products are adsorbed on the upper steam plate 12 and the lower steam plate 13 through the structure composed of the upper steam plate 12 and the lower steam plate 13. When the third electric push rod 16 moves to the center position of the rectangular installation frame 5, the piston rod of the third electric push rod 16 drives the U-shaped mounting frame 17 to rise and fall, and the output shaft of the stepping motor 18 drives the forward and reverse screws 19 to rotate, thereby driving the two clamping plates 20 to approach each other to achieve the clamping of the electronic products.

[0052] Step 4: The piston rod of the fourth electric push rod 28 pushes the receiving tray 29 to move to the bottom of the lower steam tray 13 or the positive and negative screw rods 19, and the clamped electronic products fall on the receiving tray 29 and slide in the groove body on the upper surface of the receiving tray 29 to ensure that the electronic products are on one side of the inner wall of the receiving tray 29, so as to facilitate the staff to take away the electronic products that need to be inspected.
