Description

Technical Field

[0001] This invention relates to the field of testing institutions, and in particular to a visual acquisition testing institution and testing method for popsicle sticks. Background Technology

[0002] Ice cream sticks, also known as popsicle sticks, are auxiliary tools used in making frozen foods such as ice cream. Ice cream sticks are an important component of frozen foods such as ice cream, making them easy to handle and eat, while ensuring the appearance and integrity of the food.

[0003] With the improvement of ice cream production quality, ice cream sticks need to undergo visual inspection after processing and molding to check whether the surface of the ice cream sticks is clean and to prevent ice cream sticks with impurities and black spots from entering the market. In addition, some ice cream sticks need to be engraved with product names, and the position of the name needs to be checked to prevent the name from being buried in the ice cream. The inspection method usually uses a visual acquisition camera (CCD camera). However, the existing visual inspection equipment can only inspect one side of the ice cream stick without human intervention. To ensure comprehensive inspection, the ice cream sticks need to be manually flipped, and manual sorting is required after inspection, which greatly reduces the inspection efficiency.

[0004] To address the aforementioned issues, we propose a visual acquisition and detection mechanism for popsicle sticks and its detection method. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a visual acquisition and detection mechanism and method for ice cream sticks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a visual acquisition and detection mechanism for an ice cream stick, comprising two device plates, two closely spaced conveyor belts installed between the two device plates, a mounting frame positioned above the two conveyor belts, a visual acquisition camera fixedly mounted on the mounting frame, a product feeding mechanism on the right side of the mounting frame, the product feeding mechanism comprising a vertical plate fixedly connected to one end of the two device plates away from each other, two supporting guide rails fixedly connected between the two vertical plates, two discharge boxes spaced apart between the two supporting guide rails, both discharge boxes being slidably connected to the two supporting guide rails via two sliding sleeves, each discharge box having a discharge port at its left end, a moving mechanism between the mounting frame and the product feeding mechanism, and a pushing component on the right side of the product feeding mechanism.

[0007] In the aforementioned visual acquisition and inspection mechanism for an ice cream stick, the product feeding mechanism further includes two connecting plates fixedly connected between two discharge boxes. A threaded sleeve block is fixedly connected to the connecting plate on the right side. A threaded rod is rotatably connected between the two vertical plates. The threaded rod passes through the threaded sleeve block and is threadedly connected to it. A first motor for driving the threaded rod to rotate is fixedly installed on the vertical plate in front.

[0008] In the aforementioned visual acquisition and detection mechanism for an ice cream stick, a movable opening is horizontally provided on the bottom wall of the discharge box. A movable block slides within the movable opening. A sliding rod is fixedly connected between the left and right inner walls of the movable opening. The sliding rod passes through the movable block and is slidably connected to it. A pushing block is fixedly connected to one end of the movable block inside the discharge box, and a contact block is fixedly connected to the other end of the movable block outside the discharge box. Inclined blocks are fixedly connected to both the front and rear positions of the contact block. Two extension blocks are fixedly connected to the right end of the discharge box. The two inclined blocks are symmetrically arranged and a spring is fixedly connected between them and the corresponding extension blocks.

[0009] In the aforementioned visual acquisition and detection mechanism for an ice cream stick, the pushing assembly includes a mounting plate fixedly connected to two device plates. An electric push rod is fixedly mounted on the mounting plate. The telescopic end of the electric push rod extends to the left side of the mounting plate and is fixedly connected to a push block. The push block corresponds to the position of the pushing block located above the conveyor belt.

[0010] In the aforementioned visual acquisition and detection mechanism for an ice cream stick, the dispensing box contains two first limiting plates arranged opposite each other. Four rectangularly distributed first movable rods are fixedly connected to the ends of the two first limiting plates that are far apart from each other. The four first movable rods on the same side penetrate the inner wall of the dispensing box and are fixedly connected to a first end plate. A movable plate is fixedly connected to the left end of each of the two first end plates. The left ends of the two movable plates extend to the left side of the dispensing box and are threadedly connected to a bidirectional screw. The bidirectional screw is mounted on the left end of the dispensing box via two fixed plates. A rod frame is fixedly connected to the upper end of the two fixed plates, and a rotating rod is rotatably connected to the rod frame. A bevel gear pair is provided between the rotating rod and the bidirectional screw. Multiple light rods are fixedly connected to the lower end of the first limiting plates. A second limiting plate is provided above the pushing block. Two second movable rods are fixedly connected to the right end of the second limiting plate. The two second movable rods penetrate the inner wall of the right side of the dispensing box and are fixedly connected to a second end plate. A first adjusting screw is rotatably connected to the right end of the dispensing box. The first adjusting screw penetrates the second end plate and is threadedly connected to it.

[0011] In the aforementioned visual acquisition and detection mechanism for an ice cream stick, a lifting groove is provided on the inner top wall of the discharge port, a lifting plate is slidably connected in the lifting groove, a second adjusting screw is rotatably connected to the discharge box, an adjusting plate is threadedly connected to the second adjusting screw, a movable opening communicating with the lifting groove is provided on the discharge box, and one end of the adjusting plate passes through the movable opening and is fixedly connected to the lifting plate.

[0012] In the aforementioned visual acquisition and detection mechanism for an ice cream stick, the moving mechanism includes two electric guide rails fixedly mounted on two device plates. Slider blocks are slidably connected to both electric guide rails. A vertical block is fixedly connected to the upper end of each of the two sliders. The two vertical blocks are arranged opposite each other and rotatably connected to coaxially arranged rotating shafts. Right-angle plates are fixedly connected to opposite ends of each of the two rotating shafts. A lower glass plate is fixedly connected between the two right-angle plates. Four rectangularly distributed vertical rods are fixedly connected to the lower glass plate. An upper glass plate is spaced apart above the lower glass plate. The four vertical rods slidably pass through the upper glass plate. A miniature cylinder is fixedly mounted on the right-angle plate in front of the upper glass plate. The telescopic end of the miniature cylinder is fixedly connected to the upper glass plate. A second motor that drives the rotating shafts to rotate is fixedly mounted on the vertical block in front of the upper glass plate.

[0013] A detection method for a visual acquisition and detection mechanism of popsicle sticks, comprising the following steps: S1. Adjust the positions of the first and second limiting plates in the discharge box according to the length and width of the popsicle sticks. By rotating the screw, the bidirectional screw is rotated under the transmission action of the bevel gear pair, thereby adjusting the distance between the two first limiting plates so that the distance between them is equal to the width of the popsicle stick. By rotating the first adjusting screw, the second limiting plate is moved laterally so that the distance between the second limiting plate and the inner wall of the left side of the discharge box is equal to the length of the popsicle stick. Then, the popsicle sticks to be tested are stacked in the discharge box at the position of the upright plate, so that they naturally slide to the bottom of the discharge box. Then, the second adjusting screw is rotated to move the adjusting plate up and open the discharge port so that the height of the discharge port can only allow one popsicle stick to pass through. S2. Drive the threaded rod to rotate by the first motor, which will move the two discharge boxes simultaneously. Move the discharge box containing the popsicle sticks to the top of the conveyor belt, and move the other discharge box to the corresponding vertical plate, so as to continue the work of step S1. S3. The moving mechanism moves the lower and upper glass plates to the position of the discharge port through the synchronous operation of two electric guide rails. At this time, the micro cylinder is in the extended state, and the distance between the lower and upper glass plates is the largest. Then, the electric push rod pushes the contact block through the push block, causing the moving block and the pusher block to move to the left, pushing the ice cream stick at the bottom, so that it passes through the discharge port and moves completely onto the lower glass plate. Then the electric push rod resets, and the pusher block and the moving block move to the right and reset under the elastic action of the spring, so that the ice cream stick in the discharge box falls to the bottom of the discharge box. S4. The micro cylinder drives the upper glass plate to move down and clamp the popsicle stick with the lower glass plate. Then, the electric guide rail moves the clamped popsicle stick to the bottom of the vision acquisition camera to perform the upper surface inspection. After the upper surface inspection is completed, the second motor drives the upper and lower glass plates to rotate half a turn through the rotating shaft, so that the lower surface of the popsicle stick faces upward to perform the lower surface inspection of the popsicle stick. S5. After the upper and lower surfaces of the popsicle stick are inspected, the second motor drives the upper and lower glass plates to rotate to their initial positions. At the same time, the micro cylinder extends, causing the upper and lower glass plates to move away from each other and release the clamp on the popsicle stick. When the inspection result meets the standard, the second motor drives the upper and lower glass plates to rotate 30 degrees to the left, so that the popsicle stick falls onto the left conveyor belt and is conveyed to the left. When the inspection result does not meet the standard, the second motor drives the upper and lower glass plates to rotate 30 degrees to the right, so that the popsicle stick falls onto the right conveyor belt and is conveyed to the right. S6. The second motor controls the upper and lower glass plates to be in a horizontal state, and continues with step S3.

[0014] Compared with existing technologies, the advantages of this invention are: The flip-up glass plate mechanism enables the visual acquisition camera to automatically detect the front and back surfaces of the popsicle sticks and intelligently sort them to different conveyor belts based on the detection results. The entire process requires no manual intervention, greatly improving detection efficiency.

[0015] The dual discharge box design, combined with a synchronous moving mechanism, enables parallel operation of feeding and inspection, eliminating equipment waiting time.

[0016] Through the coordinated adjustment of the bidirectional screw, limiting plate and lifting plate, it can adapt to popsicle sticks of different sizes. The glass clamp avoids blind spots in detection and significantly improves the recognition accuracy of surface impurities and printing defects. Attached Figure Description

Detailed Implementation

[0019] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] Reference Figures 1-11A visual acquisition and inspection mechanism for popsicle sticks includes two device plates 1. Two closely spaced conveyor belts 2 are installed between the two device plates 1. The two conveyor belts are defined as a left conveyor belt and a right conveyor belt. The left conveyor belt transports qualified products to the left, and the right conveyor belt transports unqualified products to the right. A mounting frame 3 is located above the area between the two conveyor belts 2. A visual acquisition camera 4 is fixedly mounted on the mounting frame 3. The visual acquisition camera 4 is a prior art industrial imaging device whose core function is to convert images captured by the lens into machine-processable signals and transmit them to a storage or analysis system via an interface. Its visual acquisition end passes through the mounting frame 3 and faces downwards. A product loading mechanism is located on the right side of the mounting frame 3. The product loading mechanism includes a vertical plate 5 fixedly connected to one end of the two device plates 1. Two supporting guide rails 6 are fixedly connected between the two vertical plates 5. Two discharge boxes 7 are spaced apart between the two supporting guide rails 6. Both discharge boxes 7 are slidably connected to the two supporting guide rails 6 via two sliding sleeves 8, and both discharge boxes 7 can move along the supporting guide rails 6. The product feeding mechanism also includes two connecting plates 9 fixedly connected between the two discharge boxes 7. A threaded sleeve block 10 is fixedly connected to the connecting plate 9 on the right side. A threaded rod 11 is rotatably connected between the two vertical plates 5. The threaded rod 11 passes through the threaded sleeve block 10 and is threadedly connected to it. A first motor 12 that drives the threaded rod 11 to rotate is fixedly installed on the vertical plate 5 at the front. The connecting plate 9 serves to connect the two discharge boxes 7, so that the two move synchronously. Then, by using the first motor 12 to drive the threaded rod 11 to rotate, the two discharge boxes 7 can be moved simultaneously through the threaded sleeve block 10. When one discharge box 7 is above the conveyor belt 2, the other discharge box 7 is on the corresponding vertical plate 5, which facilitates the feeding of ice cream sticks.

[0021] Each dispensing box 7 has a dispensing port 13 on its left end. A movable opening 14 is horizontally opened on the bottom wall of the dispensing box 7. A movable block 15 slides within the movable opening 14. A sliding rod 16 is fixedly connected between the left and right inner walls of the movable opening 14, passing through and slidably connecting to the movable block 15. A pushing block 17 is fixedly connected to one end of the movable block 15 inside the dispensing box 7. The thickness of the pushing block 17 is less than the thickness of a single popsicle stick, so it can only effectively push one popsicle stick at a time. A contact block 18 is fixedly connected to one end of the movable block 15 outside the dispensing box 7. Inclined blocks 19 are fixedly connected to the front and rear positions of the contact block 18. Two extension blocks 20 are fixedly connected to the right end of the dispensing box 7. The two inclined blocks 19 are symmetrically arranged, and springs 21 are fixedly connected between them and the corresponding extension blocks 20. Both springs 21 are tension springs and are distributed in a figure-eight shape.

[0022] The product feeding mechanism is provided with a pushing component on the right side. The pushing component includes a mounting plate 36 fixedly connected to two device plates 1. An electric push rod 37 is fixedly installed on the mounting plate 36. The telescopic end of the electric push rod 37 extends to the left side of the mounting plate 36 and is fixedly connected to a push block 38. The push block 38 corresponds to the position of the pushing block 17 located above the conveyor belt 2. The electric push rod 37 can abut against the contact block 18 through the push block 38, thereby pushing the moving block 15 to move, so that the pushing block 17 pushes the ice cream stick out from the outlet 13.

[0023] A lifting groove is provided on the inner top wall of the discharge port 13. A lifting plate 33 is slidably connected in the lifting groove. A second adjusting screw 34 is rotatably connected to the discharge box 7. An adjusting plate 35 is threadedly connected to the second adjusting screw 34. A movable opening communicating with the lifting groove is provided on the discharge box 7. One end of the adjusting plate 35 passes through the movable opening and is fixedly connected to the lifting plate 33. The second adjusting screw 34 can drive the lifting plate 33 to rise and fall, thereby adjusting the height of the lifting groove. This ensures that only one popsicle stick can pass through the discharge port 13 at a time, preventing the popsicle stick from being pulled out by friction during the pushing process. This ensures that only one popsicle stick is pushed out at a time.

[0024] The discharge box 7 is equipped with two first limiting plates 22 arranged opposite to each other. Four first movable rods distributed in a rectangle are fixedly connected to the ends of the two first limiting plates 22 that are far apart from each other. The four first movable rods located on the same side pass through the inner wall of the discharge box 7 and are fixedly connected to the first end plate 23. The first movable rods are slidably connected to the discharge box 7. The left ends of the two first end plates 23 are fixedly connected to the movable plates 24. The left ends of the two movable plates 24 extend to the left side of the discharge box 7 and are threadedly connected to a bidirectional screw 25. The bidirectional screw 25 is installed on the left end of the discharge box 7 through two fixed plates 26. The upper ends of the two fixed plates 26 are fixedly connected to the rod frame. A rotating rod 27 is rotatably connected to the rod frame. A bevel gear pair 28 is provided between the rotating rod 27 and the bidirectional screw 25. The bevel gear pair 28 plays a transmission role. Rotating the rotating rod 27 can drive the bidirectional screw 25 to rotate, which drives the two movable plates 24 to move relative to each other, thereby adjusting the distance between the two first limiting plates 22. Simply adjust the distance between the two first limiting plates 22 to the width of the popsicle sticks to effectively stack the popsicle sticks in the dispensing box 7.

[0025] Multiple guide rods 29 are fixedly connected to the lower end of the first limiting plate 22. The lower ends of the guide rods 29 are close to the inner bottom wall of the dispensing box 7, which helps to reduce frictional resistance during pushing and ensures smooth dispensing of ice cream sticks. A second limiting plate 30 is provided above the pushing block 17. Two second movable rods are fixedly connected to the right end of the second limiting plate 30. The two second movable rods pass through the inner right wall of the dispensing box 7 and are fixedly connected to a second end plate 31. A first adjusting screw 32 is rotatably connected to the right end of the dispensing box 7. The first adjusting screw 32 passes through the second end plate 31 and is threadedly connected to it. The position of the second limiting plate 30 can be adjusted by the first adjusting screw 32, thereby adjusting the distance between it and the inner left wall of the dispensing box 7. When the distance between the two is the same as the length of the ice cream stick, the ice cream sticks can be stably stacked in the dispensing box.

[0026] A moving mechanism is provided between the mounting bracket 3 and the product loading mechanism. The moving mechanism includes two electric guide rails 39 fixedly mounted on two device plates 1. Sliders are slidably connected to both electric guide rails 39. A vertical block 40 is fixedly connected to the upper end of each of the two sliders. The two vertical blocks 40 are arranged opposite each other and rotatably connected to a coaxially arranged rotating shaft 41. A right-angle plate 42 is fixedly connected to one end of each of the two rotating shafts 41. A lower glass plate 43 is fixedly connected between the two right-angle plates 42. Four rectangularly distributed vertical rods 44 are fixedly connected to the lower glass plate 43. An upper glass plate 45 is spaced apart above the lower glass plate 43. A sliding through upper glass plate 45 is provided. A miniature cylinder 46 is fixedly installed on a right-angle plate 42 in front of it. The telescopic end of the miniature cylinder 46 is fixedly connected to the upper glass plate 45. A second motor 47 that drives the rotating shaft 41 to rotate is fixedly installed on the upright block 40 in front. By setting the lower glass plate 43 and the upper glass plate 45, the popsicle stick to be inspected is clamped. The visual acquisition camera 4 can inspect the popsicle stick through the glass, and the second motor 47 can drive the lower glass plate 43 and the upper glass plate 45 to rotate, thereby flipping the popsicle stick. The inspection of the front and back of the popsicle stick can be completed without manual intervention.

[0027] A detection method for a visual acquisition and detection mechanism of popsicle sticks, comprising the following steps: S1. Adjust the positions of the first limiting plate 22 and the second limiting plate 30 inside the discharge box 7 according to the length and width of the popsicle stick. By rotating the rotating rod 27, the bidirectional screw 25 is rotated under the transmission action of the bevel gear pair 28, thereby adjusting the distance between the two first limiting plates 22 so that the distance between them is equal to the width of the popsicle stick. By rotating the first adjusting screw 32, the second limiting plate 30 is moved laterally so that the distance between the second limiting plate 30 and the inner wall of the left side of the discharge box 7 is equal to the length of the popsicle stick. Then, the popsicle stick to be tested is stacked in the discharge box 7 at the position of the upright plate 5 so that it slides naturally to the bottom of the discharge box 7. Then, the second adjusting screw 34 is rotated to move the adjusting plate 35 upward and open the discharge port 13 so that the height of the discharge port 13 can only allow one popsicle stick to pass through. S2. Drive the threaded rod 11 to rotate through the first motor 12, which drives the two discharge boxes 7 to move simultaneously. Move the discharge box 7 containing the popsicle sticks to the top of the conveyor belt 2, and move the other discharge box 7 to the corresponding vertical plate 5, so as to continue the work of step S1. S3. The moving mechanism moves the lower glass plate 43 and the upper glass plate 45 to the position of fitting the discharge port 13 through the synchronous operation of the two electric guide rails 39. At this time, the micro cylinder 46 is in the extended state, and the gap between the lower glass plate 43 and the upper glass plate 45 is the largest. Then, the electric push rod 37 pushes the contact block 18 through the push block 38, causing the moving block 15 and the pusher block 17 to move to the left, pushing the ice cream stick located at the bottom, so that it passes through the discharge port 13 and moves completely onto the lower glass plate 43. Then the electric push rod 37 resets, and the pusher block 17 and the moving block 15 move to the right and reset under the elastic action of the spring 21, so that the ice cream stick in the discharge box 7 falls to the bottom of the discharge box 7. S4. The micro cylinder 46 drives the upper glass plate 45 to move down and clamp the popsicle stick with the lower glass plate 43. Then, the electric guide rail 39 is used to move the clamped popsicle stick to the bottom of the vision acquisition camera 4 to perform the upper surface inspection. After the upper surface inspection is completed, the second motor 47 drives the upper glass plate 45 and the lower glass plate 43 to rotate half a turn through the rotating shaft 41, so that the lower surface of the popsicle stick faces upward and the lower surface of the popsicle stick is inspected. S5. After the upper and lower surfaces of the popsicle stick are inspected, the second motor 47 drives the upper glass plate 45 and the lower glass plate 43 to rotate to the initial position. At the same time, the micro cylinder 46 extends, causing the upper glass plate 45 and the lower glass plate 43 to move away from each other, releasing the clamp on the popsicle stick. When the inspection result meets the standard, the second motor 47 drives the upper glass plate 45 and the lower glass plate 43 to rotate 30 degrees to the left, so that the popsicle stick falls onto the left conveyor belt 2 and is conveyed to the left. When the inspection result does not meet the standard, the second motor 47 drives the upper glass plate 45 and the lower glass plate 43 to rotate 30 degrees to the right, so that the popsicle stick falls onto the right conveyor belt 2 and is conveyed to the right. S6. The second motor 47 controls the upper glass plate 45 and the lower glass plate 43 to be in a horizontal state, and continues with step S3.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Each of the two electric guide rails (39) has a slider slidably connected to it. Each of the two sliders has a block (40) fixedly connected to its upper end. Each of the two blocks (40) is opposite to each other and rotatably connected to a coaxially arranged rotating shaft (41). Each of the two rotating shafts (41) has a right-angle plate (42) fixedly connected to one opposite end. A lower glass plate (43) is fixedly connected between the two right-angle plates (42). (43) has four rectangular uprights (44) fixedly connected to it. An upper glass plate (45) is provided above the lower glass plate (43) at intervals. The four uprights (44) slide through the upper glass plate (45). A miniature cylinder (46) is fixedly installed on the right-angle plate (42) in front of it. The telescopic end of the miniature cylinder (46) is fixedly connected to the upper glass plate (45). A second motor (47) that drives the rotating shaft (41) to rotate is fixedly installed on the upright block (40) in front of it.

8. The detection method of the visual acquisition and detection mechanism for an ice cream stick according to any one of claims 1-7, characterized in that, The steps are as follows: S1. Adjust the position of the first limiting plate (22) and the second limiting plate (30) in the discharge box (7) according to the length and width of the popsicle stick. By rotating the screw rod (27), the double screw (25) is rotated under the transmission action of the bevel gear pair (28), thereby adjusting the distance between the two first limiting plates (22) so that the distance between them is equal to the width of the popsicle stick. By rotating the first adjusting screw (32), the second limiting plate (30) is moved laterally so that the distance between the second limiting plate (30) and the left inner wall of the discharge box (7) is equal to the length of the popsicle stick. Then, the popsicle stick to be tested is stacked in the discharge box (7) at the position of the upright plate (5) so that it slides naturally to the bottom of the discharge box (7). Then, the second adjusting screw (34) is rotated to move the adjusting plate (35) upward and open the discharge port (13) so that the height of the discharge port (13) can only pass through one popsicle stick. S2. Drive the threaded rod (11) to rotate by the first motor (12), which will drive the two discharge boxes (7) to move simultaneously. Move the discharge box (7) with the popsicle sticks to the top of the conveyor belt (2), and move the other discharge box (7) to the corresponding upright plate (5) to continue the work of step S1. S3. The moving mechanism moves the lower glass plate (43) and the upper glass plate (45) to the position of fitting the discharge port (13) through the synchronous operation of the two electric guide rails (39). At this time, the micro cylinder (46) is in the extended state, and the gap between the lower glass plate (43) and the upper glass plate (45) is the largest. Then the electric push rod (37) pushes the contact block (18) through the push block (38), causing the moving block (15) and the pusher block (17) to move to the left, pushing the ice cream stick at the bottom, so that it passes through the discharge port (13) and moves completely onto the lower glass plate (43). Then the electric push rod (37) resets, and the pusher block (17) and the moving block (15) move to the right and reset under the elastic action of the spring (21), so that the ice cream stick in the discharge box (7) falls to the bottom of the discharge box (7). S4. The micro cylinder (46) drives the upper glass plate (45) to move down and clamp the popsicle stick with the lower glass plate (43). Then, the electric guide rail (39) is used to move the clamped popsicle stick to the bottom of the visual acquisition camera (4) to perform the upper surface inspection. After the upper surface inspection is completed, the second motor (47) drives the upper glass plate (45) and the lower glass plate (43) to rotate half a turn through the rotating shaft (41) so that the lower surface of the popsicle stick faces up and the lower surface of the popsicle stick is inspected. S5. After the upper and lower surfaces of the popsicle stick are inspected, the second motor (47) drives the upper glass plate (45) and the lower glass plate (43) to rotate to the initial position. Then the micro cylinder (46) extends, so that the upper glass plate (45) and the lower glass plate (43) move away from each other and release the clamp on the popsicle stick. When the inspection result meets the standard, the second motor (47) drives the upper glass plate (45) and the lower glass plate (43) to rotate 30 degrees to the left, so that the popsicle stick falls onto the left conveyor belt (2) and is conveyed to the left. When the inspection result does not meet the standard, the second motor (47) drives the upper glass plate (45) and the lower glass plate (43) to rotate 30 degrees to the right, so that the popsicle stick falls onto the right conveyor belt (2) and is conveyed to the right. S6. The second motor (47) controls the upper glass plate (45) and the lower glass plate (43) to be in a horizontal state, and continues with step S3.
