Description

Technical Field

[0001] The present application relates to the technical field of motherboard surface treatment equipment, and in particular to a cargo stand for motherboard surface treatment equipment. Background Art

[0002] The motherboard surface treatment equipment, namely the PCBA circuit board brush cleaning machine, is a device specially used to clean PCBA (printed circuit board assembly) circuit boards. It uses a brush for physical cleaning to remove pollutants on the surface of the circuit board, such as dust, solder slag, flux residue, etc. This equipment is very common in the electronics manufacturing industry and is used to improve the reliability and performance of circuit boards.

[0003] The working principle of the PCBA brush cleaning machine is to place the PCBA on the conveyor belt of the cleaning machine, and through the movement of the conveyor belt, the PCBA passes through the brush area. The brush is usually made of soft bristles, and it brushes the surface of the PCBA by rotating or moving back and forth to brush away contaminants. At the same time, some equipment is also equipped with a spray system for spraying cleaning fluid to enhance the cleaning effect.

[0004] There is a conveyor belt consisting of two tracks with a gap between the two tracks. The mainboard is aligned with the position of the two tracks and placed on the tracks for transportation. During the transportation, a cleaning device is set below the two tracks to clean the mainboard. The mainboard is placed on the two tracks manually. Two pins are respectively provided on both sides of the mainboard. The operator places the pins on the two tracks so that the mainboard is transported by the tracks. However, manual placement of the mainboard will result in the pins not being aligned with the two tracks when the operator places the mainboard on the track, which often requires the operator to adjust when placing the mainboard, which is very troublesome. In order to solve this technical problem, a technician proposed to set a protective cover on the two tracks, stack the mainboards and place them in the protective cover, so that the mainboards are transported one by one from the protective cover by the track. However, when the mainboard is transported, it will rub against the mainboard adjacent to it, causing damage to the mainboard. For this reason, a cargo rack for mainboard surface treatment equipment is needed. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a cargo stand for motherboard surface treatment equipment, which is used to solve the technical problem in the prior art that it is difficult to accurately align the motherboard pins with the track when placing the motherboard on the track.

[0006] The above-mentioned purpose of the present application is achieved through the following technical scheme: a cargo placement bracket for a motherboard surface treatment device, comprising a placement shell, two rotating shafts respectively rotatably arranged on both sides of the placement shell, and a first limit plate fixedly connected to the rotating shafts, the rotating shaft extending out of the placement shell and fixedly connected to a crank rocker mechanism, the crank rocker mechanism is fixedly installed outside the placement shell, and the rotating shaft is located at the lower end of the placement shell.

[0007] By adopting the above technical scheme, multiple main boards are stacked and placed in a housing, so that the pins on both sides of the main board located at the bottom of the multiple main boards are placed on the first limit plate, and the multiple main boards are aligned, and then the crank rocker mechanism is started, and the crank rocker mechanism drives the rotating shaft to rotate reciprocatingly, so that the first limit plate rotates downward and then resets. When the first limit plate rotates downward, the main board located at the bottom of the multiple main boards falls off, and the other main boards are blocked by the reset first limit plate, so that the fallen main board will not rub against the main board adjacent to it, so that the main board pins can be accurately aligned with the track, and the fallen main board will not damage the main board adjacent to it.

[0008] Furthermore, a mounting bracket installed on a track is fixedly connected to the bottom surface of the placement shell, and the mounting bracket is used to prevent the mainboard from being stuck in the placement shell.

[0009] Furthermore, the mounting bracket includes two groups of support rods installed on the rails, each group of support rods includes two support rods installed on two rails opposite to each other, the support rods are hollow inside and have openings at both ends, the opening at the upper end of the support rod is larger than the opening at the lower end, the opening at the lower end of the support rod faces the access port of the rail, and the opposite side of each group of support rods has a through opening for the mainboard to pass through, and the support rods are trapezoidal.

[0010] By adopting the above technical scheme, although the setting of the first limit plate and the crank rocker mechanism enables the mainboard pins to be accurately aligned with the track, the fallen mainboard will not damage the adjacent mainboards, but since the placement shell needs to reserve the rotation space of the first limit plate, the mainboard needs a certain distance to fall on the track. During this distance, the mainboard may fall at an angle, causing the mainboard to be stuck in the placement shell. The setting of the mounting bracket solves this technical problem, because the openings at the upper ends of the four support rods are larger than the openings at the lower ends, the four pins of the fallen mainboard face the openings at the upper ends of the four support rods, and because the support rods are trapezoidal, when the mainboard is dropped between the four support rods, it will gradually decrease as the diameter of the support rods and accurately fall out from the openings at the lower ends of the support rods. In this way, the mainboard can fall smoothly onto the track, preventing the mainboard from being stuck in the placement shell.

[0011] Furthermore, an installation component is provided at the lower end of the support rod, and the installation component includes a connecting block fixedly connected to the lower end of the support rod, and the connecting block is an inverted L-shaped, and the connecting block is used to make the opening at the lower end of the support rod have a certain distance from the track access port, and one horizontal end of the connecting block abuts the track, and the end face of the horizontal end of the connecting block is fixedly connected to a side of the opening at the lower end of the support rod away from the opening of the support rod opposite to it.

[0012] By adopting the above technical solution, although the setting of the support rod can prevent the mainboard from being stuck in the housing, if the lower end of the support rod is always in contact with the track access port, it will cause the track to rub against the support rod all the time during operation, causing wear on the support rod and the track. This technical problem can be solved by installing the support rod on the track through a connecting block. The connecting block abuts against the track to support the support rod on the track, and a certain distance is left between the opening at the lower end of the support rod and the track access port, so that the track will not rub against the support rod all the time during operation, and by supporting the support rod on the track through the connecting block, the area of ​​the support rod contacting the track can be increased, and the inclined support rod can be placed more firmly.

[0013] Furthermore, the installation assembly also includes a fixed block and a connecting bolt, the fixed block is located at the lower end of the connecting block and is vertically slidably connected to the connecting block, the connecting bolt passes through the connecting block and the fixed block in turn and is threadedly connected to them, and the upper surface of the fixed block is opposite to the side of the connecting block that abuts the track.

[0014] By adopting the above technical solution, although the connecting block can increase the area of ​​the support rod contacting the track, making the inclined support rod more firmly placed, the operator will inevitably touch the support rod when placing the mainboard, which will cause the support rod to be easily separated from the track due to the thrust. The setting of the fixing block and the connecting bolt solves this technical problem. After the connecting block abuts against the track, the connecting bolt is turned so that the connecting bolt and the fixing block press the bottom of the track, so that the connecting block and the fixing block clamp the track, thereby fixing the support rod on the track. In this way, even if the operator touches the support rod when placing the mainboard, the support rod will be stably installed on the track.

[0015] Furthermore, an adjustment opening is opened on a side of the lower end of each group of support rods that is away from each other, and an adjustment component is arranged in the adjustment opening. The adjustment component includes a baffle plate that is rotatably connected to the support rod in the middle, and half of the baffle plate is located inside the support rod and the other half extends outside the support rod.

[0016] By adopting the above technical solution, although the setting of the support rod can prevent the motherboard from being stuck in the placement shell, the surface treatment of the motherboard is an assembly line operation, and the daily workload may be thousands. This may cause the support rod to have thousands of motherboard pins rubbing against the support rod every day, causing the support rod to gradually wear out and lose the effect of making the motherboard gradually flat during the placement process. At this time, only by replacing the support rod can this problem be solved, but replacing the support rod is more troublesome. The setting of the adjustment component solves this technical problem. When the pin of the motherboard falls into the support rod, if the motherboard falls at an angle, it will first contact one end of the track. Before contacting the track, it will first contact the baffle, and the baffle contacts the mainboard to generate a resistance for the mainboard, so that the mainboard will be buffered before falling onto the track, so that the end that falls later will catch up with the end that falls first, ensuring that the height difference between the two ends of the mainboard will not be too large so that the mainboard will not be stuck. The half of the baffle extending out of the support rod can provide enough rotation space for the baffle, so that even if the support rod is gradually worn and loses the effect of gradually flattening the mainboard during placement, the height difference between the two ends of the mainboard can also be not too large through the baffle, so that the mainboard will not be stuck, thereby improving the accuracy of the mainboard dropped from the placement shell.

[0017] Furthermore, half of the baffle extending out of the support rod has a connecting boss extending out of the support rod, and a connecting rod with both ends fixedly connected to the upper surface of the connecting boss is provided between each group of the support rods, and a rotating part is provided in the middle of the connecting rod, and a second limit plate located between each group of support rods and fixedly connected to the support rod is provided above the rotating part, and a limit column is vertically provided between the second limit plate and the connecting rods on both sides of the rotating part, and one end of the limit column is fixedly connected to the second limit plate and the other end abuts the connecting rod.

[0018] By adopting the above technical solution, although the setting of the baffle can generate a resistance for the mainboard, ensuring that the height difference at both ends of the mainboard will not be too large so that the mainboard will not be stuck, but if the mainboard falls from the support rod with a large inclination, the resistance provided by the baffle can only block the mainboard for a short time, so that the height difference on both sides does not change much, resulting in the two sides of the mainboard and the large height difference falling onto the track, jamming the mainboard. The setting of the connecting rod, the second limit plate and the limit column solves this technical problem. When one end of the mainboard that first contacts the track will first contact the baffle before contacting the track, the baffle begins to rotate due to the thrust, and the rotating baffle drives the connecting boss to move upward, and the upward moving connecting boss drives the connecting rod connected to the connecting boss to rotate upward, but due to the limitation of the connecting rod, when the connecting rod is driven to rotate about 80 degrees, it will press against the rotating part and cannot rotate anymore. When the mainboard is lifted off the support rod, the rear part will be in a V-shape with the support rod being parallel to the support rod, so that the mainboard will not fall off until the baffles are pressed on both sides. This ensures that the height difference between the two sides of the mainboard will not be too large to cause it to get stuck when it falls off the support rod, thereby improving the accuracy of the mainboard falling off the support rod and reducing the accident rate of the mainboard falling off the support rod. In addition, the cooperation of the baffle with the connecting rod, the second limit plate and the limit column can isolate multiple mainboards to prevent them from overlapping when they are put down, thereby making the transportation speed of the track faster and improving the efficiency of the surface treatment equipment.

[0019] Furthermore, a resetting device for resetting the connecting rod is provided at the lower end of the connecting rod.

[0020] Furthermore, the reset device includes a reset plate arranged directly below the rotating part and fixedly connected to the support rod, and a reset spring located between the reset plate and the rotating part, one end of the reset spring is fixedly connected to the reset plate, and the other end abuts the rotating part.

[0021] By adopting the above technical scheme, although the setting of the connecting rod, the second limit plate and the limit column can improve the accuracy of the motherboard falling from the support rod and reduce the accident rate of the falling motherboard, the baffle needs to rotate one circle before it can drive the connecting rod to reset, resulting in too long baffle reset time affecting the falling motherboard. The setting of the reset device solves this technical problem. The rotating part of the V-shaped connecting rod presses the reset spring. When the thrust exerted on the baffle disappears, the reset spring bounces the rotating part back to its original position. The rotating part returned to its original position drives the two ends of the connecting rod to be parallel. The parallel ends of the connecting rod return the baffle to its original position through the connecting boss. In this way, the baffle can be directly reset after it is separated from the computer motherboard without waiting too long.

[0022] Furthermore, a cotton sleeve is provided on one side of the baffle plate located inside the support rod.

[0023] By adopting the above technical solution, the cotton sleeve is used to reduce the damage caused by the mainboard hitting the baffle.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Through the arrangement of the first limit plate and the crank rocker mechanism, multiple mainboards can be stacked and placed in a housing, so that the pins on both sides of the mainboard located at the bottom of the multiple mainboards are placed on the first limit plate, and the multiple mainboards are aligned, and then the crank rocker mechanism is started, and the crank rocker mechanism drives the rotating shaft to rotate reciprocatingly, so that the first limit plate rotates downward and then resets. When the first limit plate rotates downward, the mainboard located at the bottom of the multiple mainboards falls off, and the other mainboards are blocked by the reset first limit plate, so that the fallen mainboard will not rub against the mainboards adjacent to it, so that the mainboard pins can be accurately aligned with the track, and the fallen mainboard will not damage the mainboards adjacent to it.

[0026] 2. By setting the mounting bracket, the openings at the upper ends of the four support rods are larger than the openings at the lower ends, so that the four pins of the fallen mainboard face the openings at the upper ends of the four support rods. Also, because the support rods are trapezoidal, when the mainboard is dropped between the four support rods, it will accurately fall out from the openings at the lower ends of the support rods as the diameters of the support rods gradually decrease. In this way, the mainboard can fall smoothly onto the track, thereby preventing the mainboard from being stuck in the housing.

[0027] 3. Through the setting of the adjustment group, when the pins of the mainboard fall into the support rod, if the mainboard falls at an angle, the end that contacts the track first will contact the baffle before contacting the track. The baffle contacts the mainboard and generates a resistance for the mainboard, so that the mainboard is buffered before falling onto the track, so that the end that falls later will catch up with the end that falls first, ensuring that the height difference between the two ends of the mainboard is not too large so that the mainboard will not be stuck. The half of the baffle extending out of the support rod can provide sufficient rotation space for the baffle, so that even if the support rod is gradually worn and loses the effect of gradually flattening the mainboard during placement, the height difference between the two ends of the mainboard can be not too large through the baffle, so that the mainboard will not be stuck, thereby improving the accuracy of the mainboard dropped from the placement shell.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] Example, see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 A cargo stand for a motherboard surface treatment device includes a stable placement shell 1, two rotating shafts 10 arranged on both sides of the placement shell 1, and a first limit plate 11 fixedly connected to the rotating shaft 10. The two rotating shafts 10 extend outward through the side wall of the placement shell 1 and are fixedly connected to a set of crank rocker mechanisms 2. The crank rocker mechanism 2 is securely fixedly installed on the outside of the placement shell 1, ensuring the convenience and stability of operation.

[0035] The position of the rotating shaft 10 inside the housing 1 is deliberately set at the lower end, and such a layout provides ideal support conditions for stacking motherboards. When multiple motherboards are neatly stacked inside the housing 1, the pins on both sides of the motherboard at the bottom layer will naturally rest on the first limit plate 11. Through the guidance of the first limit plate 11, it is ensured that all motherboards can maintain an aligned state, greatly improving the accuracy and efficiency of motherboard placement.

[0036] Once everything is ready, the operator only needs to start the crank rocker mechanism 2, which will drive the rotating shaft 10 to reciprocate with its unique mechanical principle. As the rotating shaft 10 rotates, the first limit plate 11 will rotate downward and automatically reset after reaching a predetermined position. In this process, when the first limit plate 11 rotates downward, the mainboard originally located at the bottom of the stack will slide off the first limit plate 11 smoothly, while the remaining mainboards will be firmly blocked by the first limit plate 11 that is reset in time, preventing them from falling.

[0037] This ingenious design not only ensures that the dropped motherboard can be accurately aligned with the track 7 below, so that the subsequent surface treatment operation can be carried out smoothly, but also effectively prevents the dropped motherboard from causing friction and damage to the adjacent motherboards during the sliding process. In this way, the pins of the motherboard can not only maintain a precise alignment, but also the integrity and safety of the entire motherboard stack are fully guaranteed, greatly improving the efficiency and quality of the motherboard surface treatment.

[0038] Although the setting of the first limiting plate 11 and the crank rocker mechanism 2 enables the mainboard pins to be accurately aligned with the track 7 without the fallen mainboard damaging the adjacent mainboards, the placement shell 1 requires reserved rotation space for the first limiting plate 11, resulting in the mainboard needing to travel a certain distance to fall on the track 7. During this distance, the mainboard may fall at an angle, causing the mainboard to be stuck in the placement shell 1. In order to solve this technical problem, the present embodiment has a mounting bracket 3 mounted on the track 7 fixedly connected to the bottom surface of the placement shell 1. The mounting bracket 3 is used to prevent the mainboard from being stuck in the placement shell 1. The mounting bracket 3 includes two groups of support rods 30 mounted on the track 7. Each group of support rods 30 includes two mounting brackets that are relatively mounted. The support rod 30 mounted on the two rails 7 is hollow inside and has openings at both ends. The opening at the upper end of the support rod 30 is larger than the opening at the lower end, and the opening at the lower end of the support rod 30 faces the access port of the rail 7. The opposite side of each group of support rods 30 is provided with a through opening for the main board to pass through. The support rod 30 is trapezoidal. Because the openings at the upper ends of the four support rods 30 are larger than the openings at the lower ends, the four pins of the fallen main board face the upper openings of the four support rods 30. Because the support rods 30 are trapezoidal, when the main board is dropped between the four support rods 30, it will accurately fall out from the lower openings of the support rods 30 as the diameter of the support rods 30 gradually decreases. In this way, the main board can fall smoothly onto the rail 7, preventing the main board from being stuck in the placement shell 1.

[0039] Although the setting of the support rod 30 can prevent the mainboard from being stuck in the housing 1, if the lower end of the support rod 30 is always in contact with the access port of the track 7, the track 7 will rub against the support rod 30 during operation, causing wear of the support rod 30 and the track 7. In order to solve this technical problem, the present embodiment provides a mounting assembly 4 at the lower end of the support rod 30. The mounting assembly 4 includes a connecting block 40 fixedly connected to the lower end of the support rod 30. The connecting block 40 is in an inverted L-shape. The connecting block 40 is used to make the opening at the lower end of the support rod 30 have a certain distance from the access port of the track 7. One end of the connecting block 40 abuts against the track 7. The end face of one horizontal end of the connecting block 40 is fixedly connected to the opening of the lower end of the support rod 30 away from the opening of the support rod 30 opposite to it. This technical problem can be solved by installing the support rod 30 on the track 7 through the connecting block 40. The connecting block 40 abuts against the track 7 to support the support rod 30 on the track 7, and a certain distance is left between the opening at the lower end of the support rod 30 and the access port of the track 7, so that the track 7 will not always rub the support rod 30 during operation, and the support rod 30 is supported on the track 7 by the connecting block 40, so that the area of ​​the support rod 30 contacting the track 7 can be increased, so that the inclined support rod 30 can be placed more firmly.

[0040] Although the connecting block 40 can increase the area of ​​the support rod 30 contacting the track 7, making the inclined support rod 30 more firmly placed, the operator will inevitably bump into the support rod 30 when placing the mainboard, which causes the support rod 30 to be easily separated from the track 7 by the thrust. In order to solve this technical problem, the present embodiment sets the mounting assembly 4 to also include a fixing block 41 and a connecting bolt 42. The fixing block 41 is located at the lower end of the connecting block 40 and is vertically slidably connected to the connecting block 40. The connecting bolt 42 passes through the connecting block 40 and the fixing block 41 in turn and is threadedly connected to them. The upper surface of the fixing block 41 is opposite to the side of the connecting block 40 abutting against the track 7. After the connecting block 40 abuts against the track 7, the connecting bolt 42 is turned so that the connecting bolt 42 and the fixing block 41 press against the bottom of the track 7, so that the connecting block 40 and the fixing block 41 clamp the track 7, thereby fixing the support rod 30 on the track 7. In this way, even if the operator bumps into the support rod 30 when placing the mainboard, the support rod 30 will be stably installed on the track 7.

[0041] Although the setting of the support rod 30 can prevent the motherboard from being stuck in the placement shell 1, the surface treatment of the motherboard is an assembly line operation, and the daily workload may be thousands of motherboards. This may cause the support rod 30 to have thousands of motherboard pins rubbing against the support rod 30 every day, causing the support rod 30 to gradually wear out and lose the effect of gradually flattening the motherboard during the placement process. At this time, only by replacing the support rod 30 can this problem be solved, but replacing the support rod 30 is relatively troublesome. In order to solve this technical problem, the present embodiment provides an adjustment port 31 on a side away from each other at the lower ends of each group of support rods 30, and an adjustment component 5 is provided in the adjustment port 31. The adjustment component 5 includes a baffle 50 rotatably connected to the support rod 30 in the middle, and half of the baffle 50 is located in the support rod 30 and the other half extends out of the support rod 30 When the pins of the motherboard fall into the support rod 30, if the motherboard falls at an angle, the end that first contacts the track 7 will contact the baffle 50 before contacting the track 7. The baffle 50 contacts the motherboard to generate a resistance for the motherboard, so that the motherboard is buffered before falling onto the track 7, so that the end that falls later will catch up with the end that falls first, ensuring that the height difference between the two ends of the motherboard is not too large so that the motherboard will not be stuck. The half of the baffle 50 extending outside the support rod 30 can provide the baffle 50 with sufficient rotation space, so that even if the support rod 30 is gradually worn and loses the effect of gradually flattening the motherboard during the placement process, the baffle 50 can also ensure that the height difference between the two ends of the motherboard is not too large so that the motherboard will not be stuck, thereby improving the accuracy of placing the motherboard dropped from the shell 1.

[0042] Although the setting of the baffle 50 can generate a resistance for the mainboard, ensuring that the height difference at both ends of the mainboard is not too large so that the mainboard will not be stuck, if the mainboard falls from the support rod 30 with a large tilt, the resistance provided by the baffle 50 can only block the mainboard for a short time, so that the height difference on both sides does not change much, resulting in the mainboard on both sides and the large height difference falling onto the track 7, and the mainboard is stuck. In order to solve this technical problem, in this embodiment, a connecting boss 51 extending outward from the support rod 30 is provided on the half of the baffle 50 extending out of the support rod 30, and each group of support rods 30 is provided with a connecting boss 51 fixedly connected to the connecting boss 51 at both ends. A connecting rod 52 is connected to the upper surface of the boss 51, and a rotating part is provided in the middle of the connecting rod 52. A second limiting plate 53 is provided above the rotating part, which is located between each group of support rods 30 and fixedly connected to the support rods 30. A limiting column 54 is vertically provided between the second limiting plate 53 and the connecting rods 52 on both sides of the rotating part. One end of the limiting column 54 is fixedly connected to the second limiting plate 53 and the other end abuts the connecting rod 52. When one end of the main board first contacts the track 7, it will first contact the baffle 50 before contacting the track 7. The baffle 50 is thrusted and starts to rotate. The rotating baffle 50 drives the connecting boss 51 to move upward, and the upward moving connecting boss 51 brings The connecting rod 52 is connected to one end of the connecting boss 51 and rotates upward. However, due to the limitation of the connecting rod 52, when the connecting rod 52 is driven to rotate about 80 degrees, it presses against the rotating part and cannot rotate any further. In this way, the baffle 50 will not rotate to be parallel to the support rod 30 to block the main board. When both ends of the main board contact the baffle 50 inside the support rod 30, the connecting rods 52 on both sides of the rotating part will rotate with the limit column 54 as the fulcrum, prying the rotating part to move it downward so that the entire connecting rod 52 and the rotating part present a V shape as the midpoint, and the rotating part moves downward to provide more rotation space for the connecting rod 52 The baffle plate 50 can be rotated to be parallel to the support rod 30 to make the main board fall down. In this way, the main board will not fall down until the two sides press the baffle plate 50. In this way, it can be ensured that the height difference on both sides of the main board will not be too large to cause it to get stuck when it falls from the support rod 30, thereby improving the accuracy of the main board falling from the support rod 30 and reducing the accident rate of the main board falling. In addition, the cooperation of the baffle plate 50 with the connecting rod 52, the second limiting plate 53 and the limiting column 54 can isolate multiple main boards to prevent them from overlapping when they are put down, so that the transportation speed of the track 7 can be adjusted faster, thereby improving the efficiency of the surface treatment equipment.

[0043] Although the arrangement of the connecting rod 52, the second limiting plate 53 and the limiting column 54 can improve the accuracy of the motherboard falling from the support rod 30 and reduce the accident rate of the falling motherboard, the baffle 50 needs to rotate one circle before it can drive the connecting rod 52 to reset, resulting in a long reset time of the baffle 50 affecting the falling motherboard. In order to solve this technical problem, the present embodiment provides a reset device 6 for resetting the connecting rod 52 at the lower end of the connecting rod 52. The reset device 6 includes a reset plate 60 arranged just below the rotating portion and fixedly connected to the support rod 30, and a reset plate 60 located at A reset spring 61 is provided between the reset plate 60 and the rotating part, and one end of the reset spring 61 is fixedly connected to the reset plate 60, and the other end abuts against the rotating part. The rotating part of the V-shaped connecting rod 52 presses the reset spring 61. When the thrust exerted on the baffle 50 disappears, the reset spring 61 bounces the rotating part back to its original position. The rotating part returning to its original position drives the two ends of the connecting rod 52 to be parallel. The two parallel ends of the connecting rod 52 make the baffle 50 return to its original position through the connecting boss 51. In this way, the baffle 50 can be directly reset after being separated from the computer motherboard without waiting for too long.

[0044] In this embodiment, a cotton sleeve 55 is provided on one side of the baffle plate 50 located inside the support rod 30 , and the cotton sleeve 55 is used to reduce the damage caused by the mainboard colliding with the baffle plate 50 .

[0045] Specific implementation process: first, the connecting block 40 is abutted against the track 7 to support the support rod 30 on the track 7, and a certain distance is left between the opening at the lower end of the support rod 30 and the access port of the track 7, and then the connecting bolt 42 is screwed to make the connecting bolt 42 press the bottom of the track 7 with the fixing block 41, so that the connecting block 40 and the fixing block 41 clamp the track 7, so that the placement shell 1 is located above the track 7, and then multiple mainboards are stacked and placed in the placement shell 1, so that the two side pins of the mainboard located at the bottom surface of the multiple mainboards are placed on the first limit plate 11, and the multiple mainboards are aligned, and then the crank rocker mechanism 2 is started, and the crank rocker mechanism 2 drives the rotating shaft to rotate reciprocatingly, so that the first limit plate 11 rotates downward and then resets. When the first limit plate 11 rotates downward, the mainboard located at the bottom surface of the multiple mainboards falls off, and the other mainboards are blocked by the reset first limit plate 11.

[0046] If the dropped motherboard falls in an inclined posture, the end that falls faster will first contact the baffle 50 and wait for the slower end to contact the other baffle 50 together, so that the connecting boss 51 of the two baffles 50 will rotate the two ends of the connecting rod 52 upward to make the connecting rod 52 present a V shape. When the computer motherboard is separated from the baffle 50, the reset spring 61 will bounce the connecting rod 52 back to its original position, and the reset connecting rod 52 will also reset the baffle 50.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
