Description

Technical Field

[0001] The present invention relates to the technical field of chip detection, and in particular to an automatic PIN pin detection device based on image recognition. Background Art

[0002] During the manufacturing and testing process of electronic products, many types of chips require their pins (PIN pins) to be tested to ensure their electrical connection and normal function. During chip production, relevant information will be printed on the side and top surface of the chip to facilitate user identification. Therefore, during production, the side and top surfaces of the chip are also tested to avoid the situation where chip information is not printed.

[0003] The pins that fail the inspection are either disconnected or skewed. The skewed pins can be corrected through subsequent work so that the chip can continue to be used. However, since the inspection work needs to be carried out again after the correction, the product production cycle is long and the inspection efficiency is low. Summary of the Invention

[0016] The upper limit block and the lower limit block are interlaced in sequence to squeeze and limit the pins, thereby driving the pins to move in different directions in sequence, thereby preventing the pins from being driven skewed.

[0017] By transferring the corrected chip, the chip can be inspected for side characters and transported to the pin inspection area, thereby ensuring that the inspection efficiency is not affected during the correction work. Since the chip to be inspected is located below the left camera, the pins of the chip to be inspected are likely to affect the shooting and inspection of the corrected chip above. Therefore, the baffle will also play a blocking role at this time, so that the baffle will block the pins of the chip to be inspected in the field of view below.

[0018] By rotating the motor to drive the clamping block to drive the chip to rotate, the lower surface of the rotated chip body is lower than the pins, and then the chip falls on the conveyor belt, thereby preventing the pins from being hit and deformed when the chip falls.

[0019] By controlling the lower clamp to rotate upward, the broken pins will slide down into the collection box, so that the broken pins can be cleaned and collected to avoid affecting the subsequent correction work. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The clamping block 105 is made of silicone material to avoid hard contact between the clamping block 105 and the chip 100 during clamping, thereby preventing damage to the chip 100 and increasing the friction between the clamping block 105 and the chip 100 .

[0036] A baffle 121 is also included; a baffle 121 is fixedly connected to each of the two facing sides of the two connecting plates 6.

[0037] The driving assembly includes an electric guide rail 111, a moving block 112, a fixed block 113, an electric push rod three 114, a connecting plate three 115 and an electric push rod four 116; an electric guide rail 111 is fixed to the left side and the right side of the inner shell 2; each electric guide rail 111 is slidably connected to two moving blocks 112; the two moving blocks 112 on the same electric guide rail 111 are commonly fixed to a fixed block 113; each fixed block 113 is fixed to two electric push rods three 114; the telescopic parts of the electric push rod three 114 on the same fixed block 113 are commonly fixed to a connecting plate three 115; each connecting plate three 115 is fixed to four electric push rods four 116; the output shafts of every two adjacent electric push rods four 116 are in opposite directions, and the connecting plate one 4 and the connecting plate two 6 are respectively fixed to the output shafts of the electric push rod four 116 in the corresponding directions.

[0038] The baffle 121 has a smooth surface, which facilitates the rapid drop of the chip 100 .

[0039] The specific working steps are:

[0040] There are three collection boxes placed on the left side of the conveyor belt 1. The three collection boxes correspond to the three areas separated by the partition frame 13 one by one, and the front area is the feeding area for qualified chips 100, the middle area is the feeding area for chips 100 with unqualified characters, and the rear area is the feeding area for chips 100 with damaged pins. The three collection boxes will respectively collect qualified chips 100, chips 100 with unqualified pins and chips 100 with unqualified characters.

[0041] When the chip 100 needs to be inspected, the chip 100 is first placed on the conveyor belt 9 with the front side facing up. The conveyor belt 9 drives the chip 100 to the left and transports it to the conveyor belt 1. During the movement, the guide plate 10 will limit the chip 100, so that the chip 100 moves to the front of the conveyor belt 9, and then moves to the conveyor belt 1. Due to the different transmission efficiency of the conveyor belt 9 and the conveyor belt 1, when the chip 100 moves to the conveyor belt 1, it will be quickly driven by the conveyor belt 1 and move into the housing 2. When the two cameras 3 on the right detect that the chip 100 is transmitted to the inspection position, the conveyor belt 1 is controlled to stop driving the chip 100 to move, and then the characters on the side of the chip 100 are photographed and recognized by the two cameras 3 on the right, and then the conveyor belt 1 is controlled to drive the chip 100 to continue to move to the left, so that the chip 100 moves to the left After the chip 100 is moved to the bottom of the square camera 3, it stops moving. At this time, the camera 3 located on the left side of the shell 2 is used to shoot, detect and identify the characters and pins on the upper surface of the chip 100, and the detection results of all cameras 3 are transmitted to the computer. Then the conveyor belt 1 continues to drive the chip 100 to move. When the chip 100 moves to the side of the push plate 12, the detection result obtained by the computer is sent to the pneumatic multi-stage push rod 11. If the pin of the chip 100 is damaged or the character is unclear, the pneumatic multi-stage push rod 11 pushes the push plate 12 to move, and performs different degrees of pushing according to the detection result, so that the push plate 12 pushes the chip 100 to move, and pushes the chip 100 to the transmission path of the corresponding area. Then the chip 100 moves and falls into the corresponding collection box. The display screen 14 will display the unqualified situation of the chip 100, which is convenient for workers to quickly understand the production quality of the chip 100.

[0042] During the above working process, when it is detected that the pin of chip 100 is unqualified, the electric push rod 101 pushes the connecting block 102 to drive the electric push rod 2 103, the fixing plate 104 and the clamping block 105 to descend, and then the electric push rod 2 103 drives the clamping block 105 to move through the fixing plate 104 to clamp the front and rear sides of the chip 100 respectively, and then controls the clamping block 105 to clamp the chip 100 and rise back to its original position, and then the electric push rod 3 114 drives the electric push rod 4 116, the connecting plate 1 4, the upper clamping block 5, the connecting plate 2 6, the lower clamping block 7, the upper limit block 8 and the lower limit block 15 to move toward the chip 100 through the connecting plate 3 115, until the upper clamping block 5, the lower clamping block 7, the upper limit block 8 and the lower limit block 15 are all aligned with the corresponding pins in the vertical direction. The pins are aligned, and then all the electric push rods 4 116 drive the connecting plate 1 4 and the connecting plate 2 6 to move toward each other in the up and down directions, so that the upper clamping block 5, the lower clamping block 7, the upper limit block 8 and the lower limit block 15 move toward the pin, and the upper limit block 8 closest to the chip 100 will first contact the root of the pin, and then the lower limit block 15 closest to the chip 100 will contact the root of the pin, and then as the connecting plate 1 4 and the connecting plate 2 6 move toward each other, the remaining upper limit blocks 8 and lower limit blocks 15 contact the pins alternately, and as the contact area between the upper limit block 8 and the lower limit block 15 and the pin gradually increases, the upper limit block 8 squeezes the crooked pin and corrects it in the front and back directions, and then the pin is pressed by the upper clamping block 5 and the lower clamping block 7, as shown in FIG. Figure 8 The state shown is shown, so as to correct the pins in the up and down directions. After the correction is completed, the upper clamping block 5 and the lower clamping block 7 can be controlled to move up and down respectively, and then the upper clamping block 5 and the lower clamping block 7 can be controlled to move left and right respectively back to their original positions, away from the pins, so that the camera 3 located on the left side of the shell 2 can shoot and detect the chip 100 again, so as to detect whether the chip 100 is qualified after correction, and then the chip 100 is placed on the conveyor belt 1, and then the pneumatic multi-stage push rod 11 pushes the push plate 12 according to the qualified and unqualified test results of the correction, and pushes the chip 100 to the corresponding transmission path, and then the chip 100 falls into the designated collection box. The above-mentioned cooperation of the upper clamping block 5, the lower clamping block 7, the upper limit block 8 and the lower limit block 15 can directly correct the chip 100 with skewed pins after the detection is completed, and then it can be directly tested again without the need to correct and re-test after getting off the machine, which greatly reduces the workload of workers and improves production efficiency.

[0043] Taking the correction work of a single pin as an example, considering that the upper limit block 8 and the lower limit block 15 gradually perform the extrusion correction work starting from the root of the pin, and move in opposite directions from the two opposite sides of the pin for extrusion correction, the pin can be balanced in the upper and lower directions during correction, avoiding the problem that the pin is only subjected to a single direction of force upward or downward, which aggravates the skewness of the pin in the upper and lower directions.

[0044] Considering that after the correction work is completed, the corrected chip 100 needs to be placed back on the conveyor belt 1, it is necessary to stop the subsequent conveying of the chip 100, which will affect the overall progress of the detection work. Therefore, when the correction work is carried out, the detection work is continued, so that the next chip 100 to be detected is first subjected to side character detection, and then moved to the bottom of the left camera 3, that is, directly below the chip 100 undergoing correction work. When the correction work is completed, the electric push rod 3 114 drives the connecting plate 2 6 to move back, and only moves a short distance, so that the baffle 121 is located below the pins of the chip 100, and then the pins of the corrected chip 100 are photographed and detected. When the correction work is completed, the electric push rod 3 114 drives the connecting plate 2 6 to move back, and only moves a short distance, so that the baffle 121 is located below the pins of the chip 100, and then the pins of the corrected chip 100 are photographed and detected. After the chip 100 inspection work is completed, the electric push rod 2 103 drives the clamping block 105 to release the chip 100 through the fixed plate 104, and the chip 100 will fall and be caught by the baffle 121, and then the electric guide rail 111 drives the moving block 112 to drive the electric push rod 3 114, the connecting plate 3 115, the electric push rod 4 116 and the connecting plate 2 6 through the fixed block 113 to drive the chip 100 to move backward. The moving distance is based on the inspection result of the chip 100, and it moves to the top of the corresponding transmission path. Then the connecting plate 2 6 drives the baffle 121 back to its original position, so that the baffle 121 is separated from the chip 100, so that the chip 100 falls on the conveyor belt 1, and then the chip 100 is driven by the conveyor belt 1 to fall on the opposite The chip 100 to be tested can be clamped by the material clamping block 105 by synchronously controlling the material clamping block 105 to descend and pick up the chip 100 to be tested, and the upper surface character and pin detection can be performed on the chip 100 to be tested. In the front-to-back direction, the width of a single area separated by the partition frame 13 is more than twice the width of the chip 100, that is, a single transmission path can accommodate at least two chips 100 to be transmitted side by side in the front-to-back direction at the same time. When the chip 100 to be tested is qualified, it is only necessary to control the electric guide rail 111 to drive the moving block 112 to move the chip 100 to the rear of the chip 100 to be tested, and the transmission block 112 located in the front area is The conveying path does not interfere with the clamping work of the clamping block 105 on the chip 100 to be inspected. At this time, the corrected chip 100 can be driven by the conveyor belt 1 to continue to move for blanking operation, so that when the correction work is in progress, the next chip 100 can be inspected for side characters and transported to the pin inspection area, thereby ensuring that the inspection efficiency is not affected when the correction work is in progress. Moreover, since the chip 100 to be inspected is located directly below the corrected chip 100, the pins of the chip 100 to be inspected are likely to affect the shooting and inspection of the corrected chip 100 above. Therefore, the baffle 121 will also play a blocking role at this time, so that the baffle 121 will block the pins of the chip 100 to be inspected in the field of view below.

[0045] Considering that the pins of chip 100 will be lower than the main body, the pins will be hit when the corrected chip 100 is directly placed on the conveyor belt 1. Therefore, when the inspection after correction is completed, the rotating motor 106 will drive the chip 100 to rotate 180 degrees through the clamping block 105, so that the lower surface of the main body of the rotated chip 100 is lower than the pins, and then the chip 100 is dropped on the conveyor belt 1, that is, it falls on the conveyor belt 1 with the pins facing upward, thereby preventing the pins of the chip 100 from being hit and deformed when it falls.

[0046] Example 2

[0047] On the basis of Example 1, Figure 5 、 Figure 7 and Figure 8 As shown, it also includes a rotating motor 201 and a collection box 202; each connecting plate 2 6 is divided into a rotating part 6001 and a connecting part 6002; the rotating part 6001 is rotatably connected to the connecting part 6002; the connecting part 6002 of each connecting plate 2 6 is fixedly connected to a rotating motor 201; the output shaft of each rotating motor 201 is fixedly connected to the corresponding rotating part 6001; each connecting part 6002 is connected to a collection box 202.

[0048] The connection portion 6002 and the collection box 202 are detachably connected, so that the collection box 202 can be quickly removed, thereby facilitating cleaning of the broken needles collected in the collection box 202 .

[0049] The upper surface of the connecting portion 6002 is inclined to facilitate the broken needles to fall into the collection box 202 .

[0050] The specific working steps are:

[0051] When the pins are squeezed and corrected, the pins that are excessively skewed may be directly squeezed off. At this time, the squeezed off pins will remain on the connecting plate 2 6 and the lower clamping block 7. Therefore, after the chip 100 is corrected and the inspection work is carried out again, the rotating motor 201 will drive the rotating part 6001 to rotate, so that the rotating part 6001 is in an upward tilted state. At this time, the rotating part 6001 will drive the lower clamping block 7 to rotate together, and the lower clamping block 7 will also be in an upward tilted state. The broken pins will slide down along the lower clamping block 7 into the collection box 202, so that the broken pins can be cleaned and collected to avoid affecting the subsequent correction work. When the rotating part 6001 tilts upward, it will drive the baffle 121 to rotate and tilt upward, so that the end of the baffle 121 is close to the chip 100, and when the baffle 121 drives the chip 100 to move, the rotating motor 201 will drive the rotating part 6001 to rotate in the opposite direction, so that the rotating part 6001 drives the end of the baffle 121 to tilt toward the conveyor belt 1, and the baffle 121 will change the contact area with the chip 100 when it rotates, so that the middle part of the rotated baffle 121 contacts the pins of the chip 100, and when the baffle 121 moves away from the chip 100, the chip 100 will slide down along the inclined baffle 121, so that the chip 100 gradually approaches the conveyor belt 1, so that the chip 100 falls smoothly on the conveyor belt 1, avoiding the chip 100 falling directly onto the conveyor belt 1, which is easy to turn in the air, causing the pins to collide with the conveyor belt 1 and deform.

[0052] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
