Description

Technical Field

[0001] This utility model relates to the field of chip processing technology, specifically to a visual inspection device for chip pin defects. Background Technology

[0002] The main function of a chip pin defect visual inspection device is to detect the integrity of chip pins, ensuring that defects are detected and addressed promptly. This device efficiently identifies chip pin defects, ensuring products meet quality standards and reducing defective products. Automated inspection equipment significantly speeds up inspection, reduces the time and cost of manual inspection, and improves production efficiency. It can detect issues such as missing pins, damage, spacing, width, curvature, span, and length differences.

[0003] The supplementary lighting equipment in existing chip pin defect visual inspection devices is fixedly installed and cannot adjust the light source illumination angle. This results in a single light source illumination angle, making the camera device susceptible to shadows during recognition, which affects the recognition effect and reduces the accuracy of chip pin defect visual inspection. Utility Model Content

[0004] The purpose of this invention is to provide a visual inspection device for chip pin defects, in order to solve the problem mentioned in the background art that the light source illumination angle cannot be adjusted, resulting in a single light source illumination angle. This makes the camera device susceptible to the influence of shadows during recognition, affecting the recognition effect and reducing the accuracy of visual inspection for chip pin defects.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a chip pin defect visual inspection device, comprising a base, wherein mounting frames are symmetrically fixedly mounted on the top of the base, and a transmission component is provided between the two mounting frames;

[0006] A drive motor is fixedly mounted on one side of the mounting frame. A worm gear is fixedly mounted on the output end of the drive motor. A worm wheel is rotatably connected to one side of the worm gear. Rotary shafts are symmetrically fixedly mounted on both sides of the worm wheel. An LED light source board is fixedly mounted on the top of the rotating shafts. The two ends of the two rotating shafts are rotatably connected between the mounting frame.

[0007] Preferably, a support frame is fixedly installed on the top of the base, an adjustable spacing component is provided between the mounting frames, and an adjustable recognition range component is provided at the bottom of the support frame.

[0008] Preferably, the transmission component includes a servo motor, which is fixedly mounted on one side of the mounting frame. One of the transmission shafts is fixedly mounted on the output end of the servo motor, and the other transmission shaft is rotatably connected to the inner wall of the mounting frame. A conveyor belt is connected to the outer end of the transmission shaft.

[0009] Preferably, the adjustable spacing assembly includes a bidirectional lead screw, which is rotatably connected to the inner wall of the mounting frame. The two ends of the bidirectional lead screw are symmetrically fixed with rotating wheels, and the two sides of the bidirectional lead screw are symmetrically threaded with positioning nuts.

[0010] Preferably, a connecting bracket is fixedly installed at the outer end of the two positioning nuts, the connecting bracket extends to the servo of the mounting frame, and a baffle is fixedly installed on the inner side of each of the two connecting brackets.

[0011] Preferably, the adjustable recognition range component includes a protective plate, which is fixedly installed at the bottom of the support frame. An electric slide rail is fixedly installed at the bottom of the protective plate, and a track block is slidably connected to the outer end of the electric slide rail.

[0012] Preferably, a connector is fixedly installed at the bottom of the track block, a camera device is fixedly installed at the bottom of the connector, and an identification head is fixedly installed at the bottom of the camera device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By rotating the worm gear driven by the motor, the illumination angle of the LED light source board is adjusted to illuminate the chips on the conveyor belt. This reduces shadows during the identification process by the camera device, enhances the recognition effect, and provides supplemental lighting to the chips on the conveyor belt. This allows the camera device to clearly identify the chip pin positions, making the visual detection of chip pin defects more accurate.

[0015] 2. The camera device is driven to move left and right by an electric slide rail, which can identify the chips on the conveyor belt. Moving left and right increases the recognition range and ensures that all chips on the conveyor belt can be identified. If the camera device is raised to increase the recognition range, it may result in unclear recognition and make it impossible to clearly distinguish whether the chip pins are damaged.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a chip pin defect visual inspection device, including a base 1, a mounting frame 2 symmetrically fixedly mounted on the top of the base 1, and a transmission component 3 disposed between the two mounting frames 2;

[0025] A drive motor 4 is fixedly installed on one side of the mounting frame 2. A worm gear 5 is fixedly installed at the output end of the drive motor 4. A worm wheel 6 is rotatably connected to one side of the worm gear 5. Rotating shafts 7 are symmetrically fixedly installed on both sides of the worm wheel 6. An LED light source board 8 is fixedly installed on the top of the rotating shaft 7. The two ends of the two rotating shafts 7 are rotatably connected between the mounting frames 2. A support frame 9 is fixedly installed on the top of the base 1. An adjustment spacing component 10 is provided between the mounting frames 2. An adjustment recognition range component 11 is provided at the bottom of the support frame 9.

[0026] The drive motor 4 drives the worm gear 6 and worm 5 to rotate, adjusting the illumination angle of the LED light source board 8 to illuminate the chip on the conveyor belt 33. This reduces shadows and enhances the recognition effect when the camera device 115 is recognizing the chip. It also provides supplementary lighting to the chip on the conveyor belt 33, enabling the camera device 115 to clearly identify the chip pin position and making the visual detection of chip pin defects more accurate.

[0027] Please see Figure 1 , Figure 2 and Figure 4 The transmission component 3 includes a servo motor 31, which is fixedly installed on one side of the mounting frame 2. One of the transmission shafts 32 is fixedly installed at the output end of the servo motor 31, and the other transmission shaft 32 is rotatably connected to the inner wall of the mounting frame 2. The outer end of the transmission shaft 32 is connected to a conveyor belt 33.

[0028] The servo motor 31 starts, thereby driving the conveyor belt 33 to rotate. The direction of the servo motor 31 is adjustable, and the conveying direction of the conveyor belt 33 is adjustable (from left to right or from right to left).

[0029] Please see Figure 1 , Figure 3 and Figure 5 The adjustable spacing assembly 10 includes a bidirectional lead screw 101, which is rotatably connected to the inner wall of the mounting frame 2. Rotary wheels 102 are symmetrically fixed at both ends of the bidirectional lead screw 101. Positioning nuts 103 are symmetrically threaded to both sides of the bidirectional lead screw 101. Connecting brackets 104 are fixedly installed at the outer ends of the two positioning nuts 103. The connecting brackets 104 extend to the servo of the mounting frame 2, and baffles 105 are fixedly installed on the inner sides of the two connecting brackets 104.

[0030] Rotating the wheel 102 drives the bidirectional lead screw 101 to rotate, thereby moving the connecting frame 104. The connecting frame 104 is connected to the baffle 105. By controlling the position of the connecting frame 104 through the bidirectional lead screw 101, the distance of the baffle 105 on the conveyor belt 33 can be controlled, which can prevent the chip from falling off the conveyor belt 33. Adjusting the position of the baffle 105 ensures that the chip on the conveyor belt 33 will not fall off from both sides of the conveyor belt 33.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The adjustable recognition range component 11 includes a protective plate 111, which is fixedly installed at the bottom of the support frame 9. An electric slide rail 112 is fixedly installed at the bottom of the protective plate 111. A track block 113 is slidably connected to the outer end of the electric slide rail 112. A connector 114 is fixedly installed at the bottom of the track block 113. A camera device 115 is fixedly installed at the bottom of the connector 114. A recognition head 116 is fixedly installed at the bottom of the camera device 115.

[0032] The camera device 115 is driven to move left and right by the electric slide rail 112, which can identify the chips on the conveyor belt 33. The left and right movement is to increase the recognition range and ensure that all chips on the conveyor belt 33 can be identified. If the camera device 115 is raised to increase the recognition range, it may lead to unclear recognition and make it impossible to clearly distinguish whether the chip pins are damaged. The electric slide rail 112 drives the camera device 115 to move back and forth, which can detect chips near the edge on the conveyor belt 33.

[0033] Working principle: The operator rotates the rotating wheel 102, which drives the bidirectional lead screw 101 to rotate. The bidirectional lead screw 101 drives the positioning nut 103 to rotate. The positioning nut 103 is limited by the connecting frame 104, allowing the positioning nut 103 to adjust linearly. The positioning nut 103 drives the connecting frame 104 to adjust, which in turn drives the baffle 105 to adjust. The distance between the two baffles 105 is adjusted to the required size. Then, the servo motor 31 is started, which drives the transmission shaft 32 to rotate. The transmission shaft 32 drives the conveyor belt 33 to adjust, which in turn drives the chip to adjust. The chip is adjusted to be below the recognition head 116. Finally, the electric slide rail 112 is started. The track 112 drives the track block 113 to adjust left and right, the track block 113 drives the connector 114 to adjust left and right, and drives the camera device 115 to adjust. The camera device 115 identifies the chip above the conveyor belt 33. During the identification process, the drive motor 4 is started, the drive motor 4 drives the worm 5 to rotate, the worm 5 drives the worm wheel 6 to rotate, the worm wheel 6 drives the rotating shaft 7 to adjust the angle, and the rotating shaft 7 drives the LED light source board 8 to adjust the angle, so as to illuminate the chip on the conveyor belt 33, so that the camera device 115 reduces the shadow part when identifying. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
