Description

Technical Field

[0001] This application relates to the technical field of sealing component testing equipment, and in particular to an automatic testing device. Background Technology

[0002] After the ring-shaped product is manufactured, the quality of the workpiece needs to be inspected. For ring-shaped products with a diameter in the range of 5mm to 60mm, the quality of the outer surface of the product can usually be used to determine whether the product is qualified.

[0003] Traditional testing equipment typically includes a glass testing tray and a conveyor belt. Workpieces are arranged by a vibrating plate and then transported to the conveyor belt. The conveyor belt then transports the sealing rings to the testing tray, and the rotating testing tray drives the workpieces through the testing device for testing.

[0004] However, due to the large size and high energy consumption of the vibratory feeder, the improved system uses an elevator to transport the workpiece to the conveyor belt. Since the workpieces transported to the conveyor belt by the elevator are usually stacked, a flattening mechanism and a guiding and arranging mechanism need to be set on the conveyor belt to flatten and arrange the workpieces in a row so that they can be transported to the inspection plate for inspection later.

[0005] Because the sealing rings on the conveyor belt need to be flattened and arranged during testing, and because the number of small sealing rings lifted by the elevator is too large relative to the amount transported by the conveyor belt in a single trip, most of the sealing rings will fall off the conveyor belt during the flattening process. The fallen sealing rings are usually collected in a collection bucket, and after the bucket is full, they are poured back into the elevator for secondary testing. Since the refilling is usually done manually, and the above equipment tests the sealing rings at a relatively fast speed, workers need to be on standby at the equipment for a long time, which requires a high level of manpower. In addition, the machine needs to be stopped when changing the collection bucket, and frequent shutdowns will also damage the motor that drives the testing disc in the equipment.

[0006] In response to the problems that arise during the use of the aforementioned traditional models, Chinese patent application number "2023229238544" provides a solution. By designing two detection discs, one above the other, and two horizontally arranged conveyor belts, the sealing rings are first transported by the elevator to the upper conveyor belt. After being flattened and arranged, the sealing rings on the conveyor belt are then transported to the detection disc on the upper side for testing.

[0007] Sealing rings that fall off the upper conveyor belt during the sorting process are guided by a guide plate on one side of the conveyor belt and fall onto the lower conveyor belt. After being sorted and arranged by the leveling and arranging devices on the lower conveyor belt, they are transported to the detection tray on the lower side for inspection. Sealing rings that fall off the lower conveyor belt during sorting fall along the guide plate into the collection bin and are collected.

[0008] The workpieces falling from the upper conveyor belt are collected and sorted a second time by the lower conveyor belt, and then transported back to the corresponding inspection plate located on the lower side for inspection. This results in a smaller number of workpieces falling into the collection bucket, which in turn reduces the interval between machine stops to pour the workpieces collected in the bucket back into the elevator hopper. This allows a single person to manage multiple inspection devices, reducing manpower consumption.

[0009] However, the design in "202322923854" still requires manual intervention and cannot achieve fully automated detection. In addition, because multiple buckets need to be placed under the detection equipment to collect finished sealing rings, waste sealing rings, sealing rings missed by the detection plate, and sealing rings falling from the conveyor belt, the space under the detection plate is limited. Therefore, the buckets need to be designed to be flat to meet the space requirements for placement and storage. This results in a small opening at the top of the bucket. In order to prevent the sealing rings from falling out of the bucket, multiple pipes need to be designed to guide the sealing rings down. Since the detection plate is surrounded by multiple pipes, detection devices, and conveyor belts, the pipes must be removed before the detection plate can be disassembled or replaced, making the replacement process quite cumbersome. Summary of the Invention

[0010] To address the problem that traditional equipment still cannot achieve fully automated detection of small sealing rings, this application provides an automatic detection device.

[0011] The automatic detection device provided in this application adopts the following technical solution: An automatic inspection device includes a frame, at least one inspection tray rotatably mounted on the frame, a transport line rotatably mounted on the frame, an inspection device mounted on the frame, and a hoist mounted on the frame. The hoist is equipped with a hopper for holding workpieces to be inspected. The hoist is used to lift and transport the workpieces in the hopper to the feed end of the transport line. The transport line is used to flatten and arrange the stacked workpieces into rows before transporting them to the inspection tray. The inspection device is used to inspect the workpieces on the inspection tray. The hopper is also used to receive workpieces falling from the transport line and workpieces that are missed in the inspection on the inspection tray. The frame is also equipped with a discharge device for outputting the inspected workpieces.

[0012] With the above technical solution, since the hopper used to feed the elevator is also used to receive the workpieces falling from the inspection line and the inspection plate, the workpieces to be inspected can be fully inspected in multiple cycles. The whole process does not require manual intervention and realizes fully automatic inspection, which greatly improves the inspection efficiency. At the same time, it eliminates the possibility of accidentally putting the discarded workpieces back into the hopper when the workpieces to be inspected are put back into the hopper in traditional equipment.

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] This application discloses an automatic inspection device 14, including a frame 1, a worktable 11, a mounting shaft 12, at least one inspection disc 13, at least one conveyor line 2, an elevator 3, and a discharge device 9. In this embodiment, two inspection discs 13 and two conveyor lines 2 are used. In this embodiment, a sealing ring is used as an example for illustration. It should be noted that this application can not only inspect sealing rings, but can also inspect annular or flat workpieces with a diameter range of 5 mm to 60 mm.

[0035] The workbench 11 is horizontal and fixedly installed on the frame 1. A detection motor 17 is fixedly installed at the center of the workbench 11. The detection motor 17 is a torque motor. The axis of the detection unit is vertical. The mounting shaft 12 is coaxially fixedly installed on the top wall of the detection motor 17. The mounting shaft 12 is coaxially fixedly connected to the output shaft of the detection motor 17. The detection motor 17 drives the mounting shaft 12 to rotate.

[0036] At least one circular connecting plate 121 is coaxially and fixedly installed on the mounting shaft 12. In this embodiment, two plates are designed, with the upper connecting plate 121 being coaxially installed on the top wall of the mounting shaft 12.

[0037] The inspection disc 13 is made of glass and consists of two discs. The two discs are ring-shaped and coaxially fixed to the top walls of the two connecting plates 121 by bolts. The frame 1 is equipped with an inspection device 14, which is used to take pictures of the front and back of the workpieces on the two inspection discs 13, and then transmit the image information to the processing center for comparison.

[0038] The detection device 14 includes an adjusting rod, a camera, and a background plate. The adjusting rod is vertically fixed to the worktable 11. The camera is fixed to the adjusting rod by bolts, and the background plate is fixed to the adjusting rod on the side where the camera is shooting by bolts. The detection plate 13 passes between the background plate and the camera. The camera is used to capture images of the sealing rings on the detection plate 13, and the background plate serves as the background when the workpiece on the detection plate 13 is photographed, preventing image recognition difficulties caused by interference from other parts of the equipment when the camera captures the image of the sealing rings.

[0039] The aforementioned detection device 14 is existing technology, and those skilled in the art can select it according to the actual situation.

[0040] The elevator 3 is located on one side of the frame 1. The frame 1 has a discharge port 111. The elevator 3 is fixedly equipped with a hopper 31, one side of which is embedded in the discharge port 111. The frame 1 is fixedly equipped with two first discharge nozzles 15. The first discharge nozzles 15 are used to blow off the undetected sealing rings on the detection plate 13. The first discharge nozzles 15 are located directly above the hopper 31. The sealing rings blown off by the first discharge nozzles 15 pass through the discharge port 111 and enter the hopper 31.

[0041] The elevator 3 is also existing technology; for details, please refer to the Chinese utility model application with application number "2024204559165". The frame 1 is rectangular, the width of the discharge port 111 is the same as the width of one side of the frame 1, and the hopper 31 is flared, with the area of ​​its upper opening being larger than the area of ​​its bottom.

[0042] In this embodiment, the transport lines 2 are designed as two lines adapted to the detection plate 13, with one transport line 2 located directly above the other transport line 2.

[0043] The transport assembly line 2 includes a first support 21, several second supports 27, a transport conveyor belt 22, a drive motor 23 for driving the transport conveyor belt 22 to rotate, a leveling mechanism 24, a sorting mechanism 25, and an output mechanism 26. The drive motor 23, the leveling mechanism 24, the sorting mechanism 25, and the output mechanism 26 are all detachably mounted to the side of the first support 21 opposite to the detection plate 13 by bolts.

[0044] The main body of the first bracket 21 is made of rectangular plate-shaped aluminum alloy profile. Two mounting plates 8 are provided at both ends of the first bracket 21. The mounting plates 8 are detachably installed on the side wall of the first bracket 21 by bolts. The two mounting plates 8 at the same end are parallel to each other and parallel to the length direction of the first bracket 21. A stop strip 83 is provided on the opposite side of the mounting plates 8.

[0045] The first bracket 21 is set horizontally, and each of the opposite sides of the mounting plate 8 is provided with a sliding groove 81, through which the mounting plate 8 passes. When the mounting plate 8 is installed in the designated position of the first bracket 21, the stop strip 83 fits and abuts against the end face of the first bracket 21. At this time, both sliding grooves 81 are horizontal and the two ends of the two sliding grooves 81 are flush with each other in the width direction of the first bracket 21.

[0046] A support shaft 82 is provided between the two mounting plates 8 at the same end. The two ends of the support shaft 82 are respectively slidably inserted into the two sliding grooves 81, and the support shaft 82 can slide until the end faces of its two ends are flush with the opposite sides of the two mounting plates 8.

[0047] The support shaft 82 is coaxially fixed with the mounting roller 84. The conveyor belt 22 is rotatably mounted on the first bracket 21 through the mounting roller 84. The first bracket 21 supports the conveyor belt 22. At the same time, the mounting plate 8 is provided with a tensioning member 85, which is used to tighten the end of the fixed support shaft 82 and thus tighten the conveyor belt 22.

[0048] The mounting plate 8 has countersunk holes at both ends. One end of the countersunk hole is connected to the end of the slide groove 81. The tensioning member 85 includes a tensioning bolt 851 rotatably mounted in the countersunk hole. One end of the tensioning bolt 851 passes through the countersunk hole and the end of the support shaft 82 in sequence, and the other end of the tensioning bolt 851 is threadedly connected to the end of the support shaft 82. Rotating the tensioning bolt 851 can drive the support shaft 82 to slide. The tensioning bolt 851 and the countersunk hole are interference-fitted.

[0049] After the support shaft 82 tightens the conveyor belt 22, the position of the end of the support shaft 82 can be observed to determine whether the conveyor belt 22 is tightened. At the same time, the installation roller 84 can be checked to see if it is installed correctly by checking whether the end face of the support shaft 82 is flush with the surface of the mounting plate 8.

[0050] Meanwhile, the mounting plate 8 is positioned by the baffle 83, which facilitates the installation and removal of the mounting plate 8 and the support of the conveyor belt 22 after the mounting plate 8 is installed, so that the mounting plate 8 is not prone to displacement after the conveyor belt 22 is tightened.

[0051] During adjustment, since the slide 81 passes through the mounting plate 8, the position of the slider can be observed more intuitively, which makes it easier to level the mounting roller 84 and the conveyor belt 22. Compared with traditional leveling, which relies on manual feeling of the tension of the conveyor belt 22, this method is more intuitive and accurate.

[0052] In this embodiment, two second supports 27 are provided. Each second support 27 includes two first support plates 271 and one second support plate 272. Both the first support plates 271 and the second support plate 272 are rectangular. The two first support plates 271 are vertically disposed at both ends of the second support plate 272 and fixed to the second support plate 272 by bolts. The other end of the first support plate 271 away from the second support plate 272 is fixedly installed to the body of the first support 21 by bolts. The frame 1 is provided with four horizontal adjustment mechanisms 5. The four second supports 27 are respectively installed on the four horizontal adjustment mechanisms 5, and are then installed on the frame 1 through the horizontal adjustment mechanisms 5.

[0053] One end of each of the two transport lines 2 extends to one of the two inspection trays 13. An output mechanism 26 is located on the transport line 2 at the inspection tray 13. This output mechanism 26 is existing technology; its principle is that the rotation of wheels pushes the sealing rings on the transport conveyor belt 22 onto the inspection tray 13. Those skilled in the art can choose the appropriate mechanism based on the actual situation. The output mechanism 26 transports the sealing rings from the transport line 2 to the inspection tray 13.

[0054] The drive motor 23 is connected to the support shaft 82 via a synchronous belt, and drives the support shaft 82 and the conveyor belt 22 to rotate.

[0055] The upper end of the conveyor line 2, away from the detection plate 13, extends to the elevator 3 and connects to its discharge end. The discharge end of the elevator 3 can place the sealing ring onto the upper conveyor line 2. The connection point between the conveyor line 2 and the discharge end of the elevator 3 is designated as the inlet end. A sealing plate is provided at the inlet end of the conveyor line 2, which is fixedly installed on the body of the first bracket 21. The sealing plate encloses the inlet end of the conveyor line 2, and the discharge end of the elevator 3 passes through the sealing plate and is located within the space enclosed by the sealing plate, making it difficult for the sealing ring placed by the elevator 3 onto the inlet end of the conveyor line 2 to fall off the conveyor line 2.

[0056] The flattening mechanism 24 is used to flatten the stacked sealing rings on the conveyor belt into a single layer, and the sorting mechanism 25 is used to sort the single-layered sealing rings on the transport line 2 into a single layer and a row. Both the flattening mechanism 24 and the sorting mechanism 25 are prior art, and those skilled in the art can select them according to actual needs.

[0057] After being sorted, the sealing rings are transported to the inspection tray 13 by the conveyor belt 22. During the sorting process, the sealing rings falling from the conveyor line 2 fall from the side of the conveyor line 2 toward the inspection tray 13.

[0058] A guide channel 4 is provided on the side of the upper transport line 2 facing the detection plate 13. The guide channel 4 is fixedly installed to the body of the first bracket 21 by bolts. The feed end of the guide channel 4 is used to receive the sealing ring falling from the transport line 2, and the discharge end of the guide channel 4 extends to the feed end of the lower transport line 2. The feed end of the lower transport line 2 is also surrounded by a sealing plate. The discharge end of the guide channel 4 is connected to the sealing plate at the top of the lower transport line 2. The sealing ring inside the guide channel 4 is discharged from the discharge port of the guide channel 4 and placed at the feed end of the lower transport line 2.

[0059] The lower conveyor line 2 is equipped with a leveling mechanism 24 and a sorting mechanism 25 located directly above the hopper 31 of the elevator 3. The lower conveyor line 2 does not have a guide channel 4. After being sorted by the leveling mechanism 24 and the sorting mechanism 25, the sealing rings falling from the conveyor line 2 fall directly into the hopper 31. Then, the elevator 3 lifts the sealing rings in the hopper 31 back to the upper conveyor line 2 for continued transport.

[0060] The hopper 31 directly receives the sealing rings falling from the detection plate 13 and the conveyor line 2, allowing the sealing rings to be directly lifted back to the conveyor line 2 by the elevator 3. This eliminates the need for manual intervention, achieving truly fully automated sealing ring detection. Furthermore, the hopper 31 replaces the original collection bucket 16 used to hold the falling sealing rings, reducing the number of collection buckets 16. Since the sealing rings in the hopper 31 are lifted by the elevator 3, the hopper 31 can be designed to be larger, resulting in a larger opening at the top. Therefore, the missing sealing rings falling from the detection plate 13 do not need to be guided through a channel and can fall directly into the hopper 31 without easily falling outside. This reduces the number of channels for placing missing sealing rings, simplifies the overall installation process, reduces the overall equipment size, and lowers manufacturing costs.

[0061] The discharge device 9 includes a first discharge mechanism 6 and a second discharge mechanism 7. The first discharge mechanism 6 includes a first discharge channel 61, a discharge conveyor belt 62, and a plurality of second discharge nozzles 63. The first discharge channel 61 is designed with two inlet ends corresponding to the two detection discs 13. The second discharge nozzles 63 are used to spray qualified sealing rings on the two detection discs 13 into the first discharge channel 61. The inlet end of the discharge conveyor belt 62 is connected to the outlet end of the first discharge channel 61. The first discharge channel 61 is used to guide qualified sealing rings to fall onto the discharge conveyor belt 62. The discharge conveyor belt 62 is used to output the sealing rings output from the first discharge channel 61.

[0062] The second discharge mechanism 7 includes a second discharge channel 71 and several third discharge nozzles 72. The second discharge channel 71 is also designed with two feed ends corresponding to the two detection discs 13. The third discharge nozzles 72 are used to blow the waste sealing rings on the two detection discs 13 into the second discharge channel 71. A waste collection bin 16 is placed on the ground at the discharge end of the second discharge channel 71. The second discharge channel 71 is used to transport the waste sealing rings inside to the waste collection bin 16.

[0063] After the sealing rings in the same batch have been tested, only the material in the waste collection bin 16 needs to be processed, which greatly simplifies the overall operation and completely eliminates the possibility of accidentally pouring the waste sealing rings in the waste collection bin 16 back into the hopper 31.

[0064] Referring to the figure, due to the above design, the discharge channel is reduced compared to traditional equipment. Therefore, the detection device 14, the first discharge mechanism 6, and the second discharge mechanism 7 can be designed on the same side of the detection plate 13, and the elevator 3 and the conveyor line 2 can be designed on the other side of the detection plate 13. When the light transmittance of the detection plate 13 decreases after long-term use, the elevator 3 and the hopper 31 can be removed from the frame 1, and the conveyor line 2 can be removed before the detection plate 13 can be disassembled. This eliminates the need to disassemble the channel before disassembling the detection plate 13, as is required in traditional equipment. The disassembly and installation of the detection plate 13 is simpler and more convenient.

[0065] Furthermore, on the mounting shaft 12, the diameter of the lower connecting plate 121 is larger than the diameter of the upper connecting plate 121. The detection disc 13 is fixed to the outer edge of the top wall of the connecting plate 121 by bolts. The minimum gap between the outer edge of the upper connecting plate 121 and the first discharge mechanism 6, the second discharge mechanism 7, and the detection device 14 allows the lower detection disc 13 to pass through after tilting. During disassembly, the upper detection disc 13 can be removed first, and then the lower detection disc 13 can be separated from the connecting plate 121 and tilted out for replacement.

[0066] The leveling mechanism 5 includes two threaded adjusting bolts 51 mounted on the frame 1. The top wall of the bolt cap of the adjusting bolt 51 is flat. The two ends of the second support plate 272 are respectively attached to the bolt caps of the two adjusting bolts 51. Both ends of the second support plate 272 have elongated holes 273, which are arranged along the length of the second support plate 272. The adjusting bolts 51 are provided with connecting parts 52 for connecting the second support plate 272. The adjusting bolts 51 have coaxially extending connecting holes 511. The connecting part 52 includes a connecting bolt 521. The two elongated holes 273 of the second support plate 272 correspond to the two connecting holes 511, and one end of the connecting bolt 521 passes through the elongated hole 273 and is threaded into the connecting hole 511. The second support plate 272 and the adjusting bolts 51 are connected by the connecting bolts 521. The length of the second support plate 272 is arranged along the width of the conveyor belt. The levelness of the conveyor line 2 can be adjusted by rotating the four adjusting bolts 51.

[0067] The adjusting bolt 51 is also threaded with a nut 53. After the adjusting bolt 51 is adjusted, the adjusting bolt 51 is fixed by tightening the nut 53 to prevent loosening.

[0068] The horizontal adjustment mechanism 5 allows for easy disassembly and installation of the transport line 2 and facilitates leveling of the transport line 2, thereby further simplifying the process of replacing the inspection disc 13.

[0069] The first support plate 271 and the second support plate 272 are detachably connected by bolts. The sealing plate on the side of the first bracket 21 facing the detection plate 13 is separated from the sealing plate on the side of the first bracket 21 facing away from the detection plate 13. When the conveyor belt 22 needs to be replaced, the first support plate 271 on the side facing away from the detection plate 13 is removed, and then the sealing plate, drive motor 23, flattening mechanism 24, sorting mechanism 25, and output mechanism 26 are removed, and the conveyor belt 22 can be disassembled. The disassembly of the conveyor belt 22 is relatively convenient. At the same time, the frame 1 is provided with a disassembly hole 18 for disassembling the first support plate 271.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
