The top of the conveyor belt 42 is located on the upper side of the support table 21 and contacts the support table 21. The lower side of the conveyor belt 42 passes through the support table 21. A wire bonding and photographing mechanism is provided in the left chamber. The wire bonding and photographing mechanism includes a connecting frame 51 connected to the top of the inner side of the left chamber. The upper part of the connecting frame 51 is connected to a pipe rack 52. The pipe rack 52 includes a vertical pipe 521 and a Z-shaped pipe 522. The vertical pipe 521 is connected to the left chamber. The upper part of the connecting frame 51 is connected to the outer wall of the vertical tube 521. The lower part of the Z-shaped tube 522 away from the vertical tube 521 is connected to the mounting shell 53. The mounting shell 53 and the Z-shaped tube 522 are both installed with a reflector 1 54. The reflector in the Z-shaped tube 522 is provided with two upper and lower ones. The upper part of the connecting frame 51 is installed with a motor 2 55. The output shaft of the motor 2 55 is connected to a mirror seat 56 located in the vertical tube 521. The mirror seat 56 is installed with a reflector 2 57. The reflector 2 57 is flush with the upper reflector 1 54 in the vertical tube 521.

[0033] The control motor 1 43 drives the rotating shaft 41 to rotate intermittently, thereby driving the conveyor belt 42 to rotate intermittently, so as to intermittently convey the chip to be tested to the left directly below the fixed plate 59. Before conveying the chip to the left, the control electric push rod 31 drives the lifting plate 32 to drive the partition 2 to move up to prevent the partition 2 from blocking the chip from being conveyed to the left. After the chip stops conveying, the control electric push rod 31 drives the lifting plate 32 to drive the partition 2 to move down and reset.

When the reflector 2 57 is aligned with the reflector 1 54 at the upper front, the reflector 2 57 displays the image of the front side of the chip. The control motor 2 55 drives the mirror holder 56 to rotate, so as to drive the reflector 2 57 to rotate, and align it with the reflector 1 54 at the upper left, upper rear and upper right in turn. The reflector 2 57 can display the images of the left side, rear side and right side of the chip in turn, so that the camera 1 58 can capture the images of the surrounding surfaces of the chip, realize comprehensive shooting and detection of the outer surface of the chip, improve the comprehensiveness of the detection, and thus improve the accuracy and reliability of the detection results.
[0034] See also Figure 1 , Figure 2 , Figure 6 and Figure 7A cleaning mechanism for cleaning the chips is provided on the right side of the housing 1. The cleaning mechanism includes two left and right rotating shafts 61 rotatably connected to the upper right side of the housing 1. The rotating shaft 61 is located on the right side of the right partition 2. Two front and rear flat belts 62 are sleeved between the two rotating shafts 61 through a pulley. A mounting plate 63 is evenly spaced between the two flat belts 62 along their motion trajectory. Three lifting rods 64 are slidably provided on the mounting plate 63 from front to back. A sponge rod 65 is connected to the bottom end of the lifting rod 64. A sponge rod 65 is provided in the chamber on the right side for pushing the lifting rod 6 The lifting and lowering push assembly includes two left and right connecting plates 66 connected to the chamber on the right side. Three groups of wave rods 67 are connected between the two connecting plates 66 from front to back. The number of each group of wave rods 67 is two. The two wave rods 67 in each group are arranged front and back. The top of the lifting rod 64 is connected to a contact rod 68. The three rows of contact rods 68 from front to back are respectively in contact with the three groups of wave rods 67 from front to back. The convex ends of each group of wave rods 67 are arranged in a staggered manner. The lifting rod 64 is covered with a spring 69. Both ends of the spring 69 The right rotating shaft 41 is connected to the right rotating shaft 61 through a transmission assembly, and the transmission assembly includes a transmission shaft 610 rotatably connected to the right front side of the housing 1. The transmission shaft 610 is connected to the right rotating shaft 41 through a belt transmission assembly 611. The belt transmission assembly 611 consists of two pulleys and a belt. The two pulleys are respectively connected to the front sides of the transmission shaft 610 and the right rotating shaft 41. The belt is sleeved between the two pulleys. The transmission shaft 610 is connected to the right rotating shaft 41 through a gear set 612. The driving shaft 61 is connected for transmission, and the gear set 612 consists of two gears, which are respectively connected to the front side of the transmission shaft 610 and the right rotating shaft 61, and the two gears are meshed. The right chamber is connected with two front and rear jet pipes 613, the front jet pipe 613 sprays toward the rear and downward, and the rear jet pipe 613 sprays toward the front and rear and downward. A circulation pump 614 is installed on the right front side of the casing 1, and the circulation pump 614 is connected to the jet pipe 613 through an air pipe 615. There is a gap between the conveyor belt 42 and the inner walls on the front and rear sides of the casing 1 for impurities to fall.
[0035] During the wire bonding detection process, there may be floating dust or impurities attached to the chip surface. These impurities will cause obstruction during the shooting process, resulting in unclear imaging, affecting the accuracy of chip imaging, and further affecting the accuracy of the detection results. The circulating pump 614 is controlled to work to input gas into the jet pipe 613 through the gas pipe 615. The jet pipe 613 then sprays gas to the chip, and uses the airflow to blow away the impurities on the chip surface to achieve the cleaning of the impurities on the chip surface. In this way, the device can clean the chip before transporting the chip to the detection area to prevent impurities from affecting the accuracy of chip imaging and the accuracy of detection results, thereby further improving the accuracy and reliability of the detection results. The right-side rotating shaft 41 rotates through the belt transmission assembly 611 to drive the transmission shaft 610 to rotate, and the transmission shaft 610 rotates through the gear set 612 to drive the right-side rotating shaft 61 to rotate, and the right-side rotating shaft 61 rotates to drive the flat belt 62 to rotate, and the flat belt 62 rotates through the mounting plate 63 to drive the lifting rod 64 to move along the wave rod 67. When the contact rod 68 moves to the raised end of the wave rod 67, the contact rod 68 is pushed upward by the raised end of the wave rod 67, thereby driving the lifting rod 64 upward and stretching the spring 69. When the contact rod 68 moves to the recessed end of the wave rod 67, under the reset action of the spring 69, the lifting rod 64 is pulled down with the sponge rod 65 to press the chip and fix it on the conveyor belt 42, so as to prevent the chip from being displaced by the wind. In this way, through the cooperation of the wave rod 67 and the contact rod 68, the sponge rod 65 can be intermittently lifted to avoid the generation of cleaning dead corners, and because the raised ends on each group of wave rods 67 are arranged in a staggered manner, the sponge rod 65 can be lifted in batches to ensure that the chip is effectively fixed on the conveyor belt 42.
[0036] See also Figure 2 and Figure 6 A dust hood 71 located on the inner side of the conveyor belt 42 is installed in the chamber on the right side. The dust hood 71 is connected to the circulation pump 614 through an exhaust pipe 72. A blocking net 73 that can be pulled out backwards is slidably provided in the dust hood 71.
[0037] The circulation pump 614 can draw the gas in the right chamber into the dust hood 71, and the impurities enter the dust hood 71 and are blocked by the blocking net 73. The clean gas filtered by the blocking net 73 is input into the jet pipe 613 through the gas pipe 615, so that the impurities can be filtered and collected to prevent the jet pipe 613 from spraying the impurities back onto the chip, thereby ensuring that the dust or impurities on the surface of the chip are cleaned.
[0038] See also Figure 2 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, a correction mechanism is provided on the support platform 21, and the correction mechanism is located in the middle chamber. The correction mechanism includes a glass plate 81 embedded in the top right side of the support platform 21, and a mounting cover 82 is connected to the right side of the inner bottom of the support platform 21. A camera 2 83 located directly below the glass plate 81 is installed on the inner bottom of the mounting cover 82. A three-axis moving platform 84 is provided on the top right side of the support platform 21, and a motor 3 85 is installed on the three-axis moving platform 84. The three-axis moving platform 84 can drive the motor 3 85 to move in three axes: up, down, front, back, left, and right. An electric suction cup 86 is installed on the output shaft of the motor 3 85. Light strips 87 are installed around the bottom of the lifting platform of the three-axis moving platform 84, and the conveyor belt 42 is a PCV transparent conveyor belt.
[0039] When the chip to be tested is placed on the conveyor belt 42 and transported to the left, the chip is prone to deflection, resulting in position deviation. The chip position deviation will affect the accuracy of the test results and the reliability and comparability of the data. When the chip to be tested is transported to the left to the top of the glass plate 81, the chip above the glass plate 81 is photographed by the second camera 83, and the image information is transmitted to the background for comparison. The chip is illuminated by the light strip 87 to ensure that the camera 2 83 takes a clear picture. If the chip to be tested is deflected, the controller controls the three-axis mobile platform 84 to drive the motor three 85 with the electric suction cup 86 to move down and contact the chip. The controller is not shown in the figure. The controller is a prior art and is not repeated here. Then the controller controls the electric suction cup 86 to suck the chip, and then the controller controls the three-axis mobile platform 84 to drive the motor three 85 with the electric suction cup 86 to move up to drive the chip to move up. Then the controller controls the three-axis mobile platform 84 to drive the motor three 85 with the electric suction cup 86 to adjust the position in the left and right and front and back directions to correct the chip so that the chip position is centered. If the chip is skewed, the controller controls the motor three 85 to drive the electric suction cup 86 to rotate, and the rotation of the electric suction cup 86 drives the chip to rotate and align, thereby achieving the correction, alignment and centering of the chip. After the chip is corrected, the controller controls the three-axis mobile platform 84 to drive the motor three 85 with the electric suction cup 86 to move down, and put the corrected chip back on the conveyor belt 42. Then the controller controls the electric suction cup 86 to release the chip. Finally, the controller controls the three-axis mobile platform 84 to drive the motor three 85 with the electric suction cup 86 to move and reset to the initial state. If the position of the chip to be detected is correct, the controller will not control the three-axis mobile platform 84, the motor three 85 and the electric suction cup 86 to work. In this way, the device can correct the position of the chip before conveying it to the detection area to avoid the chip position deviation affecting the accuracy of the detection result, thereby further improving the accuracy and reliability of the detection result.
[0040] See also Figure 2Four brushes 22 are connected to the inner bottom of the casing 1 at intervals from left to right. The brushes 22 are located on the lower side of the conveyor belt 42 and in contact with the conveyor belt 42. When the conveyor belt 42 rotates, the conveyor belt 42 can be cleaned by the brushes 22 to ensure the cleanliness of the surface of the conveyor belt 42 and avoid affecting operations such as light transmission and lighting.
