Description

Technical Field

[0001] The present invention belongs to the technical field of chip detection, and in particular relates to a chip appearance detection device. Background Art

[0002] On-board chips refer to various integrated circuit chips used in automotive electronic systems. They are key components for realizing the electronic, intelligent, and networked development of automobiles. These chips are mainly responsible for computing and processing data, managing and controlling various functional modules of the automobile, and are equivalent to the brain and heart of the automobile. They are widely used in various fields such as engine control, airbags, ABS systems, smart cockpits, autonomous driving, and vehicle networking. From traditional automotive electronic control to cutting-edge intelligent technologies, they all rely on the support of on-board chips.

[0003] During the chip production process, it is necessary to perform appearance inspection on the rolled chips. The chip is wound on a reel, and then one end of the chip is pulled over and connected to an empty reel on the other side of the inspection body. Then the two reels start to rotate, driving the chip through the inspection channel in the inspection seat to complete the appearance inspection of the chip. Although this can effectively inspect the chip, the installation and disassembly steps of the two reels are relatively complicated and the operation time is long. After each inspection of a roll of chips, it takes a long time to inspect the next roll of chips, which affects work efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a chip appearance detection device to solve the problems existing in the background technology.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-4As shown, a chip appearance inspection device of the present invention comprises a body 1, a control panel 101 is arranged on the front side of the body 1, a detection seat 11 is arranged on the upper side of the body 1, a detection channel 12 is arranged in the detection seat 11, a bracket 13 is arranged on the upper side of the body 1, the bracket 13 is provided with a probe 14 pointing to the detection channel 12, a support rod 15 is arranged on the upper side of the body 1, a display screen 16 is arranged on the upper side of the support rod 15, mounting frames 2 are arranged on the left and right sides of the detection seat 11, two mounting frames 2 are arranged at one end away from each other, motors 22 are arranged on the lower side of the two mounting plates 21, and two The motors 22 are both transmission-equipped with a rotating part 23 that passes through the mounting plate 21. The middle sides of the two mounting plates 21 are both rotatably equipped with a rotating shaft 24. The two rotating shafts 24 are connected to a rotating plate 25 at one end away from the motor 22. The upper and lower sides of the rotating plate 25 are both rotatably equipped with a driving shaft 26. A rectangular hole 3 is provided on the side of the rotating part 23 away from the motor 22. A first spring 31 is provided in the rectangular hole 3. A slider 32 is fixedly connected to the first spring 31. A magnet block 33 that can be magnetically connected to the driving shaft 26 is provided on the outer surface of the slider 32. The rotating plate 25 is provided with a trigger mechanism matching the slider 32.

[0029] The reel with the chip wound around it is mounted on the outer surface of the driving shaft 26 at the lower left side, and the empty reel is mounted on the outer surface of the driving shaft 26 at the lower right side. The staff passes the tape of the chip to be pasted through the detection channel 12 of the detection seat 11, and fixes the end on the outer surface of the empty reel. The motors 22 on both sides start working at the same time to drive the rotating member 23 to start rotating. Because the slider 32 in the rotating member 23 pushes out the magnet block 33 under the action of the extension of the first spring 31, the magnet block 33 is adsorbed on the corresponding end of the driving shaft 26. Therefore, when the rotating member 23 rotates, the driving shaft 26 is driven to start rotating through the magnet block 33. When the driving shafts 26 on both sides rotate, the reel on one side releases the chip, and the reel on the other side winds the chip, thereby driving the chip to slide through the detection channel 12, and the appearance of the chip is inspected by the probe 14, and the inspection result is displayed on the display screen 16.

[0030] When the chip is being tested, the staff will fix another reel with the chip wound on it to the driving shaft 26 on the upper left side, and another empty reel on the driving shaft 26 on the upper right side. This design allows the next set of reels with the test chip wound on them and the reel with the chip to be wound to be installed when the chip is being tested.

[0031] When the inspection of the lower group of chips is completed, the staff will drive the slider 32 to move to the side away from the driving shaft 26 through the trigger mechanism, the first spring 31 begins to compress, and the slider 32 drives the magnet block 33 to separate from the driving shaft 26. At this time, the staff rotates the rotating shaft 24 by ninety degrees, and the rotating shaft 24 drives the rotating plate 25 by ninety degrees to rotate the upper driving shaft 26 to the lower side. The driving shaft 26 on the side where the chip inspection is completed is located on the upper side, so the new reel without the detected chip is located on the lower side and is located in the correct working position. The empty reel on the other side without the wound chip is also located in the correct working position on the lower side. At this time, the work of the trigger mechanism is cancelled, and the magnet block 33 extends out of the rectangular hole 3 under the extension of the first spring 31 and is connected to the new driving shaft 26. At this time, the new chip can be directly inspected, and the staff can replace the two reels on the upper side. With this design, after the two reels on the lower side complete the chip inspection, the upper and lower reels can be directly swapped, thereby reducing the interval time between two chip inspections and improving work efficiency.

[0032] The trigger mechanism includes an inner cavity 34 arranged in the mounting plate 21 and surrounding the rotating member 23. A collar 35 magnetically connected to the slider 32 is slidably mounted in the inner cavity 34. The inner wall of the inner cavity 34 away from the motor 22 is connected to a pressure supply component.

[0033] When the staff injects pressure into the inner cavity 34 through the pressure supply assembly, the pressure in the inner cavity 34 is increased, which can push the ring 35 to slide in the inner cavity 34. Since the ring 35 is magnetically connected to the slider 32, the ring 35 drives the slider 32 to be retracted into the rectangular hole 3, driving the first spring 31 to be compressed, thereby driving the magnet block 33 to separate from the drive shaft 26. When the pressure supply of the pressure supply assembly is canceled, the slider 32 can be extended out of the rectangular hole 3 under the action of the extension of the first spring 31, thereby driving the magnet block 32 to connect with the new drive shaft 26.

[0034] The pressure supply assembly includes a cavity 351 arranged in the mounting plate 21 and surrounding the rotating shaft 24. A second spring 36 is arranged in the cavity 351. A sealing ring 37 slidably assembled in the cavity 351 is connected to one side of the second spring 36. Hydraulic oil is filled in the cavity 351 on the side of the sealing ring 37 close to the rotating plate 25. A connecting pipe 371 communicating with the inner cavity 34 is arranged on the inner wall of the cavity 351 on the side of the sealing ring 37 close to the rotating plate 25. Connecting rods 38 extending out of the cavity 351 are symmetrically arranged on the side of the sealing ring 37 away from the rotating plate 25. A slide groove 4 is arranged on the outer surface of the rotating shaft 24 away from the rotating plate 25. A slide bar 41 is slidably assembled in the slide groove 4. The slide bar 41 is provided with a handle 42 sleeved on the outer surface of the rotating shaft 24. The handle 42 is rotatably connected to a rotating ring 43 fixedly connected to the two connecting rods 38.

[0035] When the staff needs to replace the upper and lower reels, the staff can press the handle 42. When pressing the handle 42, the slide bar 41 is driven to slide in the slide groove 4. When the handle 42 is pressed, the sealing ring 37 in the cavity 351 is pushed through the rotating ring 43 and the two connecting rods 38, driving the second spring 36 to start compressing. The sealing ring 37 pushes the hydraulic oil in the cavity 351 through the connecting pipe 371 into the inner cavity 34, which can increase the pressure in the inner cavity 34. Then the handle 42 is turned. When the handle 42 is turned, the rotating shaft 24 is driven to rotate, and the rotating shaft 24 can drive the rotating plate 25 to rotate. When the staff releases the handle 42, the sealing ring 37 is driven to reset under the action of the extension of the second spring 36, and the hydraulic oil in the inner cavity 34 is sucked into the cavity 351, thereby driving the handle 42 and the rotating ring 43 to reset.

[0036] The left and right sides of the detection seat 11 are both provided with pressing wheels 44 that match the detection channel 12. The design of the pressing wheels 44 on both sides can press the chip entering the detection channel 12 to ensure the stability of the chip entering the detection channel 12.

[0037] The left and right sides of the mounting frame 2 are both provided with a pressing rod 45. The design of the pressing rod 45 can press the strip of the chip attached thereto, so that the strip can be stably wound on the reel.

[0038] A storage box is provided at the lower side of the machine body 1, and a box cover 46 matching the storage box is provided at the front side of the machine body 1. The design of the storage box is convenient for the staff to store tools.

[0039] Two cooling fans 47 are provided on the side of the machine body 1. The design of the two cooling fans 47 can improve the cooling effect of the machine body 1.

[0040] Adsorption blocks 5 are provided on the upper and lower sides of the two mounting plates 21, and limit blocks 51 are provided on the upper and lower sides of the two rotating plates 25, which are magnetically connected to the adsorption blocks 5. When the rotating shaft 24 rotates, the rotation force of the staff's hand overcomes the magnetic force of the adsorption blocks 5 and the limit blocks 51, and then the rotating plate 25 can be rotated. After the rotating plate 25 rotates 90 degrees, the two adsorption blocks 5 are adsorbed on the two limit blocks 51 again. This design can limit the rotating plate 25 and ensure that the rotating plate 25 rotates 90 degrees accurately.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
