Description

Technical Field

[0001] The present invention relates to the technical field of electronic component detection, and in particular to a device for detecting damage of electronic components. Background Art

[0002] Electronic components are basic elements in electronic circuits. They are usually individually packaged and have two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with specific functions, such as resistors, capacitors, inductors, transistors, amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electronic components is to solder them to printed circuit boards. During the production process of electronic components, surface defects often appear on the surface of electronic components, such as casing cracking, blistering, scratches, etc. Therefore, in the final stage of electronic component production, the appearance of electronic components is often inspected to ensure the quality of electronic component production.

[0003] A capacitor detection device with publication number CN116242838A in the prior art performs all-round detection of the characters of the lead capacitor and the defects on the surface of the body through the first detection mechanism, the second detection mechanism, the third detection mechanism and the fourth detection mechanism, so that the detection result is more accurate and achieves a better detection effect. When detecting the lead capacitor, it does not require frequent manual picking, and will not cause secondary damage to it. At the same time, it also improves the yield of the lead capacitor.

[0004] Although it is possible to conduct a comprehensive inspection of capacitors, there are still some defects in the actual inspection process. Since the electronic components inspected by the inspection device are directly placed in the material frame, there is a lack of automatic box changing function. Therefore, when the material frame is full, workers are required to replace the material frame. In addition, the existing electronic component visual inspection device has a very fast inspection speed, which can reach hundreds of electronic components per minute. Therefore, workers are required to be on duty next to the machine to frequently replace the material frame, which is not only time-consuming and labor-intensive, but also the manual box changing cannot be quickly connected. After the inspection is completed, the electronic components are easy to fall out of the material frame, thereby causing damage to the electronic components, which will affect the production quality of the device.

[0032] The bottom end of the fixed frame 8 is slidably connected with a lower L-shaped plate 11, the inner side of the upper L-shaped plate 4 is slidably connected with a sliding frame 12, the inner side of the sliding frame 12 is slidably connected with a sliding block 13, the side wall of the sliding block 13 passes through the side wall of the fixed frame 8 and is fixedly connected to the side wall of the lower L-shaped plate 11, the inner side of the fixed frame 8 is provided with a limiting mechanism for limiting the movement of the material frame, the inner side of the upper L-shaped plate 4 is provided with a driving mechanism for driving the sliding frame 12 to move back and forth, the inner side of the upper L-shaped plate 4 is respectively provided with an upper transverse groove 14, an inclined groove 15 and a lower transverse groove 16, the side wall of the sliding block 13 is fixedly connected with a round rod 17, and the round rod 17 is movably connected to the inner side of the lower transverse groove 16, the top of the placement plate 7 is provided with a U-shaped groove 18, the inner side of the U-shaped groove 18 A U-shaped plate 19 is slidably connected, a right-angle block 20 is fixedly connected to the middle position of the top of the U-shaped plate 19, and a plurality of upper springs 21 are fixedly connected between the bottom of the U-shaped groove 18 and the bottom of the U-shaped plate 19, a through groove 22 is provided at the bottom end of the lower L-shaped plate 11 and at a position corresponding to the right-angle block 20, and the through groove 22 is provided to prevent the lower L-shaped plate 11 from being obstructed by the right-angle block 20, and a slide groove 23 adapted to the sliding block 13 is provided on the side wall of the fixed frame 8, and the slide groove 23 is used to prevent the sliding of the sliding block 13 from being obstructed, the upper transverse groove 14 is provided above the placement plate 7, and the lower transverse groove 16 is provided next to the fixed frame 8, and the two ends of the inclined groove 15 are respectively connected to the adjacent two ends of the upper transverse groove 14 and the lower transverse groove 16;

[0033] The driving mechanism includes a driving motor 24, a supporting frame 25 is fixedly connected to the inner side of the upper L-shaped plate 4 and located above the placement plate 7, a threaded rod 26 is rotatably connected to the inner side of the supporting frame 25, and the driving motor 24 is fixedly connected to the side wall of the supporting frame 25, a driving block 27 is threadedly connected to the outer wall of the threaded rod 26, and the bottom of the driving block 27 is fixedly connected to the top of the sliding frame 12, and a guide rod 39 is fixedly connected to the inner side of the supporting frame 25, and the guide rod 39 is arranged to penetrate the inner side wall of the driving block 27;

[0034] In order to improve the automation efficiency of the device, a recessed groove is provided on the top of the placement plate 7, and a gravity detector 32 is provided inside the groove, and the gravity detector 32 is electrically connected to the drive motor 24 through the controller. Through the setting of the gravity detector 32, the value of gravity detected by the gravity detector 32 is set before use, and then when the capacitor in the material frame on the placement plate 7 collects the specified gravity, the gravity detector 32 detects that the rated gravity is reached, and then transmits a signal to the controller, and the controller controls the drive motor 24 to start, so as to realize the automatic frame change of the device without manual operation, and further improve the automation efficiency of the device.

[0035] In order to prevent the upper material frame from falling directly and affecting the reset of the lower L-shaped plate 11 after the material frame on the lower L-shaped plate 11 is removed, the limiting mechanism includes a limiting spring 40, a pair of upper frames 30 are fixedly connected to the outer wall of the fixed frame 8 and located below the frame inlet 9, and a lower frame 31 is fixedly connected to the side wall of the fixed frame 8 away from the side of the sliding frame 12, and the inner sides of the upper frame 30 and the lower frame 31 are both connected to the limited block 29 by sliding through the inner side of the fixed frame 8, and the upper surface of the limiting block 29 is connected to the upper surface of the material frame on the lower L-shaped plate 11. The surfaces are flush, three limit springs 40 are provided, and two of the limit springs 40 are fixedly connected between the upper frame 30 and the limit block 29, and the other limit spring 40 is fixedly connected between the lower frame 31 and the limit block 29, and the limit block 29 located inside the lower frame 31 is tilted away from the side of the frame inlet 9, and the inclined surface of the limit block 29 is arranged on the side close to the frame outlet 10, so as to facilitate the side plate 33 of the side wall of the lower L-shaped plate 11 to squeeze the limit block 29 to slide into the lower frame 31;

[0036] The limit spring 40 is compressed at the same time, and then the material frame at the top of the fixed frame 8 loses its restriction and falls onto the lower L-shaped plate 11.

[0037] In order to prevent the material frame from being lifted up by the right-angle block 20 due to its light weight, the side wall of the lower L-shaped plate 11 is fixedly connected to the side plate 33, and a movable groove adapted to the side plate 33 is opened on the inner side of the fixed frame 8, and a push rod 34 is slidably connected to the side wall of the side plate 33, and a pair of lower springs 35 are fixedly connected between the outer wall of the push rod 34 and the outer wall of the side plate 33, and the upper L-shaped plate 4 is fixedly connected to an L-shaped abutment plate 36 located next to the placement plate 7, and the side wall of the L-shaped abutment plate 36 is inclined, and the bottom of the push rod 34 is flush with the upper surface of the material frame placed on the lower L-shaped plate 11, and a rotating groove is opened on the side wall of the push rod 34, and a roller 28 is rotatably connected to the inner side of the rotating groove;

[0038] When the lower L-shaped plate 11 is inside the fixed frame 8, the roller 28 is not restricted at this time, so the push rod 34 will be pushed out under the elastic force of the lower spring 35 to avoid affecting the normal falling of the material frame in the fixed frame 8. Then, when the lower L-shaped plate 11 moves out of the fixed frame 8, the roller 28 will be driven to move to the side of the L-shaped abutment plate 36, and the roller 28 will slide to the side of the L-shaped abutment plate 36 along the inclined surface of the side wall of the L-shaped abutment plate 36. At the same time, the push rod 34 will be pushed to slide in the lower L-shaped plate 11, so that the push rod 34 moves to the top of the material frame, and at the same time, the lower spring 35 is compressed, thereby limiting the upward sliding position of the material frame on the lower L-shaped plate 11 to avoid being lifted up by the right-angle block 20 and affecting the normal replacement of the device.

[0039] In order to collect the capacitors evenly in the material frame, a discharging motor 41 is fixedly connected to the top of the upper L-shaped plate 4 and below the placement plate 7, a disc 42 is fixedly connected to the output end of the discharging motor 41, a pull rod 37 is fixedly connected between the eccentric part of the top of the disc 42 and the bottom of the placement plate 7, and a pull block 38 is fixedly connected to both sides of the top of the U-shaped plate 19. By setting the pull block 38, the left and right positions of the material frame can be restricted to ensure that the material frame can be driven to move simultaneously when the placement plate 7 moves;

[0040] After the material frame is replaced on the placement plate 7, the discharge motor 41 is controlled to start and drive the disc 42 to rotate, thereby pulling the pull rod 37 at the eccentric position to rotate, and at the same time, the placement plate 7 is pulled to slide between the support plates 6 through the pull rod 37. When the pull rod 37 rotates to the other end of the disc 42, the continued rotation of the disc 42 will push the pull rod 37 to drive the placement plate 7 to slide in the opposite direction, thereby realizing the back and forth movement of the placement plate 7, which can ensure that the capacitor falls evenly in the material frame. It should be noted that since the placement plate 7 slides between the support plates 6, it will not move arbitrarily with the pull rod 37, ensuring the stable operation of the device.

[0041] When the capacitor surface is inspected, the capacitor is transported to the capacitor conveyor line 2 through the vibration plate, and then the capacitor is inspected by the visual inspection machine 1. Then, the qualified capacitor is discharged through the discharge hopper 3 and falls into the material frame on the placement plate 7, and the unqualified capacitor is discharged through another discharge port on the capacitor conveyor line 2. Then, when the gravity detector 32 detects that the capacitor in the material frame is stored to the specified gravity, it will control the drive motor 24 to start and drive the threaded rod 26 to rotate, and then drive the threaded drive block 27 to move, and at the same time drive the sliding frame 12, the sliding block 13 and the lower L-shaped plate 11 to move, so as to push the material frame on the lower L-shaped plate 11 out of the fixed frame 8. At the same time, the downward sliding position of the material frame above the material frame is limited by the limiting mechanism, and the round rod 17 is driven to slide on the inner side of the lower transverse groove 16. Then, the drive block 27 drives the lower L-shaped plate 11 to completely move out of the fixed frame 8, and then the round rod 17 moves to the end of the lower transverse groove 16 and slides into the inclined groove 15;

[0042] Then, under the pressure of the inclined groove 15, the sliding block 13 is pushed to slide upward in the sliding frame 12, thereby driving the lower L-shaped plate 11 and the material frame to move upward, and then, under the drive of the driving block 27, the round rod 17 is pushed out of the inclined groove 15 and slides into the upper transverse groove 14, thereby driving the lower L-shaped plate 11 to move above the placement plate 7. Before the material frame moves to the placement plate 7, the side wall of the material frame will squeeze the inclined surface of the right-angle block 20, pushing the right-angle block 20 and the U-shaped plate 19 to slide downward, while compressing the upper spring 21, and then the lower L-shaped plate 11 continues to slide, pushing away the collected materials on the placement plate 7. The material frame, at the same time, the empty material frame is docked with the full material frame, and the capacitor falling from the discharge hopper 3 is seamlessly collected, and then the full material frame is pushed to the material frame conveyor line 5 next to it under the push of the lower L-shaped plate 11, and the full material frame is driven to the next process under the action of the material frame conveyor line 5, and then the lower L-shaped plate 11 moves the empty material frame to the specified position, and the driving motor 24 can be controlled to drive the threaded rod 26 to rotate in the opposite direction, thereby driving the sliding frame 12, the sliding block 13 and the lower L-shaped plate 11 to move in the opposite direction for reset;

[0043] At this time, the material frame moves out of the right-angle block 20, and the U-shaped plate 19 and the right-angle block 20 are pushed upward under the elastic force of the upper spring 21. Then, when the lower L-shaped plate 11 is reset, the through slot 22 on the lower L-shaped plate 11 will pass through the top of the right-angle block 20, and the right-angle block 20 will abut against the side wall of the material frame to prevent the material frame from being displaced when the lower L-shaped plate 11 is pulled out. Then, the lower L-shaped plate 11 repeats the above operation in reverse and slides into the fixed frame 8, squeezing the limiting mechanism, so that the material frame at the top of the fixed frame 8 loses its limit and falls onto the lower L-shaped plate 11 under its own gravity. At the same time, the material frame conveying line 5 next to the fixed frame 8 will convey empty material frames, so that the material frames are accumulated on the fixed frame 8. This is repeated to realize automatic frame changing of the device, so that there is no need for manual long-term duty beside the machine to carry the material frames.

[0044] The basic principles, main features and advantages of the present invention are shown and described above.

[0045] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
