TECHNICAL FIELD

[0001] The present application relates to the technical field of PIN detection. More particularly, the present application relates to an intelligent PIN and character detection machine with a material distribution function. BACKGROUND

[0002] PIN is a basic element of electronic components, used for electrical connection between electronic components. In order to ensure the stability of electrical connection, the length, width and spacing of the PIN of the electronic components need to be detected after the production of the electronic components. When the existing equipment detects the electronic components, unqualified electronic components are sorted into a storage box, and then the unqualified electronic components in the storage box are manually taken out periodically. However, when a single batch of electronic components contains a large number of unqualified products due to production process errors, the unqualified electronic components in the storage box should be taken out by the worker in time and continuously. However, the storage box is relatively deep, which will interfere with the worker in taking out the unqualified electronic components. SUMMARY

[0015] Compared with the prior art, the present application has the following advantages:

[0016] I.

In this process, the electronic part on the receiving plate can be limited by the groove I to avoid sliding phenomenon. When the unqualified rate is low, the groove I for preventing the electronic part from sliding is also used to avoid the collision phenomenon of the PIN feet of adjacent electronic parts, thereby avoiding the secondary damage phenomenon of the electronic parts. The pressure sensor I for controlling the movement of the receiving plate can also be used to control the detection operation to be suspended when there are many unqualified products, so as to avoid the falling phenomenon of the electronic parts in the groove I due to the manual taking out.

[0017] II. The fixed block is abutted against the rear side of the first electronic part, so that the pressure sensor continuously monitors the pressure, thereby avoiding the false judgment that the electronic part in the groove has been taken out by the artificial, and avoiding the problem of the electronic part falling due to the false judgment control continuing the detection operation;

[0018] III. The linkage block one and the linkage block two cooperate to control the forward movement of the pressure sensor one away from the electronic part, thereby avoiding the problem of the pressure sensor one being pressed for a long time due to the long time span from the groove one being full of electronic parts to the groove two being full of electronic parts, and avoiding the problem of low service life of the pressure sensor one.

[0028] Example 1

[0029] A smart pin and character detection machine with material sorting function, such as Figures 1-5 As shown, the system includes an electrical control box 1, a connecting plate 2, an electric conveyor belt 3, an electric conveyor belt 4, and a buffer platform 5. The connecting plate 2, made of metal, is located on the outside of the electrical control box 1. The electric conveyor belt 3 and the electric conveyor belt 4 are mounted on the connecting plate 2. The buffer platform 5 is bolted to the connecting plate 2. The system also includes a guide plate 6, a guide plate 7, a receiving plate 8, a telescopic cylinder 9, a frame 10, a detection assembly, a material distribution assembly, and a drive assembly. The support portions of the electric conveyor belts 3 and 4 are bolted together to the guide plate 6, which is made of metal. The electric conveyor belt 1 (6) and the electric conveyor belt 2 (4) are connected by bolts to a guide plate 2 (7), which is made of metal. Both the guide plate 1 (6) and the guide plate 2 (7) have beveled sections. A receiving plate 8 is connected to the connecting plate 2. The receiving plate 8 has a groove 1 (91) and a groove 2 (92). Two telescopic cylinders 1 (9) are bolted to the receiving plate 8. All telescopic cylinders 1 (9) have a frame 10 fixedly connected to their telescopic ends. The frame 10 is slidably connected to the receiving plate 8. A detection component is connected to the connecting plate 2. A material distribution component is connected to the connecting plate 2. A drive component is connected to the connecting plate 2.

[0030] Both groove 1 91 and groove 2 92 are flared on the side near the electric conveyor belt 2 4, making it easier for electronic components to be pushed into groove 1 91 and groove 2 92.

[0031] The detection assembly includes a camera group 201 and a light source panel 202; the camera group 201 is connected to the connecting plate 2, and the camera group 201 is used to detect the length, width and spacing of the PIN pins of the electronic component, and to detect the characters of the electronic component; the light source panel 202 is bolted to the connecting plate 2.

[0032] The material distribution assembly includes a telescopic cylinder 203 and a push plate 204; the telescopic cylinder 203 is bolted to the connecting plate 2; the telescopic end of the telescopic cylinder 203 is fixedly connected to the push plate 204, which pushes the electronic components to move.

[0033] A pressure sensor is installed on the buffer platform 5.

[0034] The drive assembly includes an electric slide rail 205 and an electric slider 206; the electric slide rail 205 is bolted to the connecting plate 2; the electric slider 206 is slidably connected to the electric slide rail 205, and the electric slider 206 is fixedly connected to the receiving plate 8. When the electric slide rail 205 and the electric slider 206 are activated, the electric slider 206 drives the receiving plate 8 to move left and right.

[0035] It also includes auxiliary components, including pressure sensor 207 and pressure sensor 208; pressure sensor 207 is mounted on the receiving plate 8 and is located in groove 91; pressure sensor 208 is mounted on the receiving plate 8 and is located in groove 92.

[0036] First, the electronic component to be inspected is placed on the upper right side of the electric conveyor belt 3. The component has pins on both its left and right sides. The electric conveyor belt 3 moves the component to the left. Guided by the angled sections of the guide plates 6 and 7, the component moves into the gap between them. At this point, the guide plates 6 and 7 limit the component's forward and backward position. When the component moves to the center behind the light source panel 202, the electric conveyor belts 3 and 4 stop moving, halting the component's movement. Then, the camera group 201 visually inspects the length, width, and spacing of the component's pins, and simultaneously visually inspects the characters on the component. The electric conveyor belts 3 and 4 then... Conveyor belt 4 continues to move the electronic component to the left. If the electronic component is qualified, it is transported to the buffer platform 5 via the electric conveyor belt 4. After the buffer platform 5 is full of electronic components, the electronic components are manually removed from the buffer platform 5. Specifically, a pressure sensor can be installed on the buffer platform 5. When the pressure sensor is triggered, it indicates that the buffer platform 5 is full of electronic components. If the electronic component is unqualified, it is transported to the front of the push plate 204 via the electric conveyor belt 4. At this time, the electronic component is located directly behind the groove 91. The electric conveyor belt 4 stops moving and then the push plate 204 is driven forward by the telescopic cylinder 203. The push plate 204 pushes the electronic component forward, thereby pushing the unqualified electronic component onto the receiving plate 8, completing the detection of the electronic component's PI N pins and characters, and also completing the sorting operation of qualified and unqualified electronic components.

[0037] Under normal circumstances, there will only be a very small number of defective electronic components in the entire batch. This means that the receiving plate 8 will be filled with defective electronic components for a long period of time. During this period, the frame 10 will block and limit the electronic components placed on the receiving plate 8. In other words, the receiving plate 8 and the frame 10 together form a box shape to collect the defective electronic components, preventing the electronic components on the receiving plate 8 from being accidentally knocked off by the workers when working around this device. Afterwards, the defective electronic components will be removed by the workers periodically.

[0038] When a batch of electronic components contains a large number of defective products due to errors in the production process, the frequency of defective electronic components detected by the camera group 201 increases. At this time, the electronic components on the receiving plate 8 should be removed frequently by the operator. However, the deep frame 10 will cause interference to the manual removal operation. Therefore, the telescopic cylinder 9 is activated. The telescopic cylinder 9 moves the frame 10 downward, so that the frame 10 is away from the outside of the electronic components, exposing the defective electronic components on the receiving plate 8 so that they can be removed by the operator.

[0039] After the frame 10 moves downward away from the outside of the electronic component, the frame 10 stops limiting the electronic component. At this time, the electronic component on the receiving plate 8 is at risk of slipping. Therefore, a groove 91 is opened on the receiving plate 8. When a defective electronic component is detected, the push plate 204 will push the defective electronic component to the groove 91. During the short period between the electronic component being pushed onto the receiving plate 8 and being manually removed, it can be limited by the groove 91 to prevent it from slipping.

[0040] Under normal circumstances, the defect rate of electronic components is low. Push plate 204 pushes the first defective electronic component into the rear of groove 91. Then, push plate 204 pushes the second defective electronic component forward, causing it to push the first defective electronic component to the front of groove 91. The second defective electronic component moves to the rear of groove 91. During this process, the forward movement of the first defective electronic component compresses pressure sensor 207, causing it to detect pressure. This indicates that groove 91 is full of electronic components. At this time, pressure sensor 207 sends an electrical signal, controlling the electric slide rail 205 and electric slider 206 to start. Electric slider 206 drives the receiving plate 8 and its components to move to the right, causing groove 92 to move to the front of push plate 204, and then pushes... Plate 204 pushes the third and fourth defective electronic components into groove 2 92 and presses pressure sensor 208, causing pressure sensor 208 to detect pressure, which indicates that the receiving plate 8 is full of electronic components. At this time, pressure sensor 208 issues an alarm message to remind the operator to remove the electronic components from the receiving plate 8. Under the limiting action of groove 1 91 and groove 2 92 on the receiving plate 8, adjacent electronic components are spaced apart, thereby avoiding collision between the pins of adjacent electronic components and thus preventing secondary damage to the electronic components. That is, groove 1 91, which is used to prevent electronic components from slipping, is also used to prevent collision between the pins of adjacent electronic components, thereby preventing secondary damage to the electronic components.

[0041] When the defect rate of electronic components is high, if the manual staff cannot remove the first defective electronic component from the rear of the groove 91 in time, the pusher plate 204 will push the second defective electronic component into the groove 91 and cause the first defective electronic component to press the pressure sensor 207. This causes the pressure sensor 207 to send an electrical signal, controlling the electric conveyor belts 3 and 4 to stop moving, thereby pausing the inspection operation. This is to prevent the pusher plate 204 from continuing to push the third defective electronic component into the groove 91 and causing it to fall. In other words, the pressure sensor 207, which is used to control the movement of the receiving plate 8 when there are few defective products, can also be used to control the pause of the inspection operation when there are many defective products, so as to prevent the electronic components from falling because the manual staff cannot remove them from the groove 91 in time.

[0042] In use, when the defect rate is high, the telescopic cylinder 9 moves the frame 10 downwards away from the outside of the electronic component, exposing the electronic component on the receiving plate 8. This makes it easier for the operator to remove the electronic component, improving efficiency and convenience. During this process, the groove 91 can limit the electronic component on the receiving plate 8 to prevent it from slipping. When the defect rate is low, the groove 91, which prevents the electronic component from slipping, also prevents the pins of adjacent electronic components from colliding, thus avoiding secondary damage to the electronic component. The pressure sensor 207, which controls the movement of the receiving plate 8, can also be used to control the pause of the detection operation when there are many defective products, preventing the electronic component from falling because the operator cannot remove it from the groove 91 in time.

[0043] Example 2

[0044] Based on Example 1, such as Figure 6 and Figure 7 As shown, it also includes a limiting component, which includes a spring 209 and a fixing block 2010; four springs 209 are fixedly connected to the receiving plate 8; a fixing block 2010 is fixedly connected to each spring 209, and the fixing block 2010 is slidably connected to the receiving plate 8; the fixing block 2010 is provided with an inclined surface, and the fixing block 2010 blocks and limits the electronic components.

[0045] After the pusher plate 204 presses the two electronic components onto the pressure sensor 207, the telescopic cylinder 203 moves the pusher plate 204 back to its original position. At this time, the rear of the two electronic components in the groove 91 is not restrained, causing the pressure sensor 207 to no longer detect pressure. This leads to a misjudgment that the electronic components in the groove 91 have been manually removed, resulting in a misjudgment of the control continuing the detection operation, and thus pushing the third electronic component into the groove 91, causing the electronic component to fall. Therefore, the pusher plate 204 pushes the two electronic components forward... During the process, the edge of the electronic component contacts the fixed block 2010 and pushes the fixed block 2010 to move, compressing the spring 209. After the two electronic components move to their limit positions, the sharp corner of the fixed block 2010 is aligned with the gap between the two electronic components. When the telescopic cylinder 203 drives the push plate 204 to move back to its original position, the spring 209 rebounds and drives the fixed block 2010 to move back to its original position, so that the fixed block 2010 abuts against the rear side of the first electronic component, thereby enabling the pressure sensor 207 to continuously monitor the pressure and avoid misjudgment.

[0046] In use, the fixing block 2010 is pressed against the rear side of the first electronic component, so that the pressure sensor 207 continuously monitors the pressure, thereby avoiding the misjudgment that the electronic component has been removed from the groove 91, and thus avoiding the problem of the electronic component falling due to the continued detection operation caused by the misjudgment.

[0047] Example 3

[0048] Based on Example 2, such as Figures 5-7 As shown, it also includes a protective component, which includes a connecting block 2011, a first linkage block 2012, a second spring 2013, and a second linkage block 2014; the connecting block 2011 is slidably connected to the receiving plate 8, and the connecting block 2011 is made of alloy material; the first linkage block 2012 is bolted to the connecting block 2011, and the first linkage block 2012 is provided with an inclined surface; the first linkage block 2012 is fixedly connected to two second springs 2013, and the second springs 2013 are fixedly connected to the receiving plate 8; the second linkage block 2014 is fixedly connected to the bracket of the second electric conveyor belt 4, and the second linkage block 2014 is provided with an inclined surface, and the second linkage block 2014 cooperates with the first linkage block 2012.

[0049] Both linkage block 1 2012 and linkage block 2 2014 are made of wear-resistant material to improve service life.

[0050] Both the first guide plate 6 and the second guide plate 7 are made of smooth material, which can reduce the friction force on the electronic components and thus prevent wear and tear on the electronic components.

[0051] For electronic components in a normal production batch, only a very small number of defective components exist in the entire batch. This results in a long time span during which the receiving plate 8 is filled with defective components. Groove 1 91 fills with components before Groove 2 92, causing pressure sensor 207 to be continuously compressed during the period between when Groove 1 91 and Groove 2 92 are filled. This reduces the lifespan of pressure sensor 207. Therefore, after Groove 1 91 is filled with components, the electric slider 206 moves the receiving plate 8 to the right, causing Groove 2 92 on the receiving plate 8 to be compressed. The plates 204 are aligned so that the push plate 204 can push the electronic components into the groove 2 92. During the movement of the receiving plate 8 to the right, it drives the linkage block 1 2012 to contact the linkage block 2 2014 to the right. Under the limiting action of the linkage block 2 2014, the linkage block 1 2012 is forced to move forward and compress the spring 2 2013. The linkage block 1 2012 drives the connecting block 2011 to move forward. The connecting block 2011 drives the pressure sensor -207 to move forward away from the electronic components, thereby stopping the pressure sensor -207 from being squeezed and improving its service life.

[0052] In use, by cooperating with linkage block 1 2012 and linkage block 2 2014, pressure sensor 1 207 is controlled to move forward away from the electronic components. This avoids the problem of pressure sensor 1 207 being subjected to pressure for a long time due to the long time span between when the electronic components are filled in groove 1 91 and when the electronic components are filled in groove 2 92. This avoids the problem of low service life of pressure sensor 1 207.
