Description

Technical Field

[0001] This utility model pertains to fireworks product testing equipment, specifically relating to a fuse testing device for paper tube fireworks. Background Technology

[0002] With the continuous improvement of people's living standards, fireworks, as a form of entertainment that produces sound and light, have appeared in various events around the world. Paper tube fireworks, as high-end fireworks, are widely used in grand ceremonies or performances. In the production process of paper tube fireworks, all procedures require manual operation and process inspection. However, with increasing emphasis on production safety and improved production efficiency, current paper tube fireworks production has generally achieved semi-automated assembly line production. Combination fireworks are produced and inspected through a combination of human and machine methods. This not only improves production efficiency but also reduces production costs for fireworks manufacturers, while simultaneously ensuring the safety of combination fireworks production.

[0003] Traditional inspection methods for paper tube fireworks involve manual visual inspection. This involves checking the integrity of the paper tube shape and the quality of the fuse (including the number, length, and any faulty fuses) to identify defects. Defects in fuse quality (including the number, length, and faulty fuses) can prevent the fireworks from igniting properly, and can cause changes in the paper tube shape such as dents, deformation, or the inability to properly insert the inner tube. When visually inspecting the fuse, due to the small inner diameter and depth of individual paper tubes, and the fuse being located inside, external lighting is required, and the eye must be highly focused on the observation point. During production, prolonged and intense visual observation can easily lead to eye fatigue, causing defects in the integrity of the paper tube shape and the quality of the fuse (including the number, length, and faulty fuses) to go undetected, resulting in significant quality defects in the paper tube fireworks. The impact of traditional manual operation methods: 1. Manual operation requires continuous visual inspection, which can easily lead to visual fatigue; 2. Production personnel are prone to batch quality accidents due to negligence; 3. Unshaped fireworks are irregular in shape, affecting the product's shape and quality.

[0004] In response to the problems of manual inspection of paper tube fireworks, the existing technologies on the market for the inspection of paper tube fireworks (Patent Publication No.: CN117553640 A A method for inspecting paper tube fireworks) and the devices for the inspection of paper tubes and leads of paper tube fireworks (Patent Publication No.: CN221238245 U A device for the inspection of paper tubes and leads of paper tube fireworks) have largely met the requirements of automatic inspection, significantly improved the production quality and efficiency of paper tube fireworks, reduced the labor intensity of workers during production, and avoided the misjudgment caused by manual inspection. However, in actual use, (1) because the specifications and types of paper tube fireworks often change during actual production, the paper tube diameter, paper tube length, number of paper tubes, and paper thickness of different specifications and types of paper tube fireworks are all different. The existing technologies (Patent Publication No.: CN117553640A) A method for detecting paper tube fireworks: When detecting paper tube fireworks of different specifications and diameters, different guide extrusion plates on different deformation components need to be replaced to accommodate the different vertical positions of the outer circumference. This results in numerous parts and cumbersome adjustments when producing different products. Furthermore, when detecting paper tube fireworks of the same specification and inner diameter, variations in paper thickness lead to significant differences in the outer diameter of the paper tube (existing paper tube winding machines can only set the number of paper layers). For example, a paper tube with an inner diameter of 30mm has a designed outer diameter of 34.5mm, but the actual value varies between 34.1mm and 35mm. This results in a difference in the actual position of the outer perimeter of the paper tube firework tube, which was originally in the same position in the vertical direction. Since the continuous protrusion of the lead extrusion plate on the set deformation component is a fixed value, when the outer perimeter of the paper tube firework tube is squeezed or stretched under this condition, the continuous protrusion of the lead extrusion plate and the outer perimeter cannot achieve an ideal correspondence, resulting in an unsatisfactory squeezing or stretching effect. It cannot effectively achieve the movement of the lead inside the firework tube to make the overlapping lead produce a dynamic deformation effect, thus affecting the test results; (2) Existing technology (Patent Publication No.: CN221238245 U A paper tube and fuse detection device for paper tube fireworks: During the detection process of paper tube fireworks, due to unstable input air pressure or uneven paper tube diameter at the assembly machine, the outlet resistance of the assembly machine fluctuates. Under these circumstances, the pushing stroke of the pushing cylinder of the assembly machine is affected, causing the pushed paper tube fireworks to not accurately reach the tape wrapping position. This results in a situation where a single tape wraps around two paper tube fireworks. In such cases, existing technology cannot effectively avoid or provide early warnings. The glue on the paper tubes of the fireworks, still wet from being pushed out of the assembly machine, can cause the tape to become entangled before the fireworks are placed on the mounting platform or when the shaping cylinder pushes them out at full stroke after inspection. This can lead to the fireworks breaking apart or rotting under external force. Rotting results in wasted raw materials, while breaking apart increases the labor cost of manual repairs and affects normal production efficiency. Utility Model Content

[0047] The rotating connector 7 can be a hinge, or it can be a universal damping ball joint connector, etc.

[0048] See Figure 1 , Figure 9 The paper tube firework ball photographing and detection device 3 is located on the axial front of the end of the detection conveyor belt assembly 105, and includes a vertical motion module 301, a horizontal motion module driven by the vertical motion module 301 that can move up and down, and a photographing and detection device driven by the horizontal motion module that can move horizontally back and forth.

[0049] The horizontal motion module includes a first horizontal motion module 303 and a second horizontal motion module 302. The photographic detection device includes a main photographic detection device 310 and a secondary photographic detection device 311, which are respectively mounted on the first horizontal motion module 303 and the second horizontal motion module 302 and can move horizontally back and forth.

[0050] The purpose of setting up the first horizontal motion module 303 and the second horizontal motion module 302 is to correspond to the paper tube firework spheres conveyed by the conveyor belt device 5. In order to adapt to the size of the paper tube firework spheres, they can be the same length or one long and one short.

[0051] The vertical motion module 301, the first horizontal motion module 303, and the second horizontal motion module 302 have the same structure. Each includes a base plate 305 with an optical axis 304, a synchronous belt 308 driven by a synchronous motor 306 and a synchronous pulley 307 on the base plate 305, and a slider 309 fixed on the synchronous belt 308 and sliding along the optical axis 304. The base plate 305 in the vertical motion module 301 is connected to the conveyor belt assembly connecting frame 10 through the mounting beam 12. The base plates 305 in the first horizontal motion module 303 and the second horizontal motion module 302 are fixed on the slider 309 in the vertical motion module 301. The main imaging detection device 310 and the auxiliary imaging detection device 311 are respectively fixed on the slider 309 in the first horizontal motion module 303 and the second horizontal motion module 302.

[0052] See Figure 1 , Figure 2 , Figure 10 The frame includes a conveyor belt assembly connecting frame 10, a load-bearing frame 4, and a testing frame 5. The front conveyor belt assembly 101 and the testing conveyor belt assembly 105 are mounted on the conveyor belt assembly connecting frame 10. The conveyor belt assembly connecting frame 10 is mounted on the lifting mechanism 13 via a support beam 11. The lifting mechanism 13 is mounted on the load-bearing frame 4. The mounting beam 12 is fixed to the conveyor belt assembly connecting frame 10. The load-bearing frame 4 is fixed to the ground.

[0053] See Figure 10 The lifting mechanism 13 includes two screw guide blocks 1307 spaced apart on the load-bearing frame 4, a screw 1305 vertically mounted on the screw guide blocks 1307, a fixed seat 1302 with a built-in worm gear on the top of the screw 1305, and a screw flange seat 1306 on the screw 1305. Each fixed seat 1302 is equipped with a rotary handle 1301 connected to the worm gear. The built-in worm gear is connected to the screw 1305 and the coupling 1303 respectively. The two fixed seats 1302 are connected to the connecting rod shaft 1304 through the coupling 1303. Each screw flange seat 1306 is fixedly mounted with a support beam 11. The conveyor belt assembly connecting frame 10 is fixedly mounted on the two support beams 11.

[0054] When the handle 1301 is rotated clockwise (R1) or counterclockwise (R2), the worm gear inside the fixed seat 1302 drives the connecting rod shaft 1304 to rotate synchronously, thereby driving the worm gear inside the other fixed seat 1302 to rotate synchronously as well. Under the rotational switching motion of the worm gears inside the two fixed seats 1302, the two screws 1305 rotate simultaneously, driving their respective screw flange seats 1306 to reciprocate up and down. Since the conveyor belt assembly connecting frame 10 is connected to the screw flange seat 1306 through the support beam 11, the conveyor belt assembly connecting frame 10 also reciprocates up and down. The height of the front conveyor belt assembly 101 and the detection conveyor belt assembly 105 can be adjusted according to the working conditions.

[0055] In actual use, the equipment of this utility model is equipped with a main control system 8 and a manual operating console 9 at adjacent positions. The main control system 8 is used for the transmission and reception of all program instructions and the display and prompting of test results during the actual production and testing process. The manual operating console 9 is used for the temporary storage of the tested paper tube fireworks during the actual production and testing process and to facilitate manual processing of defective products by workers.

[0056] Working principle Production workers adjust the production status of the assembly machine according to the number of rows and layers of paper tube fireworks according to the factory's production task requirements. Based on the adjusted height of the assembly machine, they adjust the height of the lifting mechanism so that the top surface of the conveyor belt assembly is compatible with the bottom surface of the assembly machine's outlet position.

[0057] See Figure 1 , Figure 5 —6、 Figure 11 —12, the main control system 8 is activated to execute the detection program. The front conveyor belt assembly 101 begins conveying motion. Simultaneously, the stop levers 108C of the first stop assembly 108 on the front conveyor belt assembly 101 and the second stop assembly 108' on the detection conveyor belt assembly 105 extend to complete the stop action and maintain it. The gantry baffle motion drive component 201D in the gantry baffle position assembly 201 executes the action to complete the downward closing of the gantry baffle 201B, and the assembly machine discharges material. The paper tube fireworks are pushed to the feed position A of the front conveyor belt assembly 101 in the direction of the arrow. If the anti-blocking sensor 103 detects the paper tube fireworks W1 for more than a set time during the conveying process, it means that the paper tube fireworks are stuck together [the rear end of the front paper tube fireworks W1 and the front end of the rear paper tube fireworks W1 are wrapped and stuck together by the adhesive tape J, causing the paper tube fireworks W1 entering the front conveyor belt assembly 101 to slip and stop, such as...]. Figure 13[As shown in (b)], this signal is fed back to the main control system 8, which issues an alarm to remind the worker to handle the situation, removing the clumps of paper tube fireworks W1 from the front conveyor belt assembly 101, so that the paper tube fireworks W1 on the front conveyor belt assembly 101 are in a non-clumped normal state, as shown. Figure 13 As shown in (a). When the front conveyor belt assembly 101 transports the paper tube firework pellet W1 to the assembly position B, it is blocked by the stop lever 108C of the first stop assembly 108 and cannot move with the front conveyor belt assembly 101. The sensing signal here instructs the assembly assembly 104 whether to perform the pushing movement according to the number of rows of paper tube firework pellets. At this time: (1) When the number of paper tube columns of paper tube firework ball W1 is less than or equal to 7, the push plate 104B of the ball assembly component 104 extends and pushes the paper tube firework ball W1 forward to the side of the belt 101C of the front conveyor belt component 101 and then resets. After the ball assembly machine finishes producing the next ball, the front conveyor belt component 101 performs the same conveying action according to the same procedure to convey the next paper tube firework ball W1 to the ball assembly position B and place it side by side with the previous paper tube firework ball W1 to complete the ball assembly. This ensures that the subsequent inspection time is less than the ball assembly time. (2) If the number of paper tube columns of the paper tube firework pyrotechnic is greater than 7, the pyrotechnic assembly 104 will not move and will not assemble.

[0058] When the detection position sensor 109 on the detection conveyor belt assembly 105 (see...) Figure 12 When the sensor signal indicates that there is no paper tube firework at this position, the stop lever 108C of the first stop assembly 108 on the front conveyor belt assembly 101 retracts to release the stop function. The detection conveyor belt assembly 105 then begins conveying. The paper tube firework at the assembly position is conveyed by the front conveyor belt assembly 101 and enters the correction position C of the detection conveyor belt assembly 105. Position correction is then performed under the obstruction of the stop lever 108C of the second stop assembly 108' on the detection conveyor belt assembly 105. At this time, the correction position sensor 106 (see...) Figure 4 The system issues a command to the first gear assembly 108 on the front conveyor belt assembly 101 to resume gearing function. Simultaneously, based on the timed command from the sensing signal at the calibration position, the second gear assembly 108' on the conveyor belt assembly 105 is deactivated, and the paper tube firework ball at calibration position C is conveyed to detection position D. The detection position sensor 109 (see...) Figure 12 The system issues a command to restore the second gear component 108' on the detection conveyor belt assembly 105 to its gear function. When the detection conveyor belt assembly 105 stops operating, the photographic detection process is then initiated, primarily detecting the state of the side guide r and internal connecting s of the paper tube firework ball W1 inside the paper tube. Process 1: The rotary drive 601 on the gantry baffle assembly 201 extends, causing the gantry tilting plate 201C to rotate to the left by angle α. Simultaneously, the rotary drive 601 on the shaping assembly 202 retracts, causing the shaping tilting plate 202B to rotate by angle α. Subsequently, the shaping drive 202C on the shaping assembly 202 extends. The paper tube firework ball W1 to be inspected on the detection position D tilts to the left at angle α under the clamping of the gantry tilting plate 201C and the shaping tilting plate 202B. At this time, the imaging and detection assembly 3 performs the first image detection of the state of the inner circumference guide r and connecting guide s of each paper tube of the paper tube firework ball W1 [see...]. Figure 14 (a)]; Process 2: The rotary drive 601 on the gantry baffle assembly 201 retracts, causing the gantry tilting plate 201C to rotate to the right by angle α. Simultaneously, the rotary drive 601 on the shaping assembly 202 extends, causing the shaping tilting plate 202B to rotate by angle α. The paper tube firework ball W to be inspected on the detection position D tilts to the right at angle α under the clamping of the gantry tilting plate 201C and the shaping tilting plate 202B. At this time, the imaging and detection assembly 3 performs a second imaging and detection of the state of the inner circumference guide r and connecting guide s of each paper tube of the paper tube firework ball W1 [see...]. Figure 14 (b)]; Process 3: See Figure 7 The rotary drive 601 on the gantry baffle assembly 201 performs a restoration action, causing the gantry tilting plate 201C to return to its original position. Simultaneously, the rotary drive 601 on the shaping assembly 202 performs a restoration action, causing the shaping tilting plate 202B to return to its original position. The paper tube firework ball W1 to be inspected on the detection position D is restored and corrected under the clamping of the gantry tilting plate 201C and the shaping tilting plate 202B. At this time, the imaging and detection assembly 3 performs a third imaging detection of the state of the inner circumference guides r and connecting guides s of each paper tube of the paper tube firework ball W1 [see...]. Figure 14 (c)]; Process 4: After the photo inspection is completed, the shaping drive 202C on the shaping unit 202 performs a slight retraction action, so that the paper tube firework ball W1 at the inspection position D is in an unclamped state. Then, the gantry baffle motion drive 201D in the gantry baffle unit 201 performs an action to open the gantry channel upward together with the gantry baffle 201B and the gantry tilting plate 201C. Then, the shaping drive 202C on the shaping unit 202 performs an extension action, pushing the inspected paper tube firework ball W2 to the inspected position E on the manual operating table 9. Then, the gantry baffle motion drive 201D in the gantry baffle unit 201 performs an action to close the gantry channel downward together with the gantry baffle 201B and the gantry tilting plate 201C, starting the next inspection process. The main control system unit 8 displays the inspection analysis results. If the inspection result is a non-conforming product, the main control system unit 8 will use both voice prompts and buzzer alarms to remind the workers to pay attention and handle the issue promptly.

[0059] The above-mentioned method of using the gantry baffle assembly 201 and the shaping assembly 202 to clamp the paper tube firework ball and tilt it at an angle 'a' to change its normal rectangular shape before taking a picture is based on (1) the glue between the paper tubes in the paper tube firework ball that has just been pushed out of the assembly machine has not yet solidified, and the paper tube firework ball is still in a loose state. It is easy to deform under the action of external force. Therefore, with the help of the gantry baffle assembly 201 and the shaping assembly 202, it is easy to obtain a tilted state at the set angle 'a'; (2) in processes 1 and 2, the inside of each paper tube is photographed when the paper tube firework ball is tilted (the surrounding and connecting lines may overlap), and in process 3, the inside of the paper tube is photographed when the paper tube firework ball is not tilted. The state of the surrounding and connecting lines inside the paper tubes on both sides of the paper tube firework ball is different before and after tilting. By taking a picture, the problem that the lines inside the paper tubes on both sides may overlap vertically and cause the lines to be unable to be detected correctly can be solved.

[0060] The photographic detection device locates the inside of each paper tube by taking pictures based on the image data of the opening position of each paper tube, and obtains the image data of the lead wire. The main control system component 8 performs data processing and comparative analysis based on the image data of the lead wire inside each paper tube under different shapes of the paper tube firework, and determines whether the paper tube firework is qualified.

[0061] The tilt angle 'a' of the paper tube firework in the above-mentioned photo-taking process 1 and photo-taking process 2 is generally 1 to 10º, with a preferred range of 3 to 5º, based on actual measurement results. The tilt angle 'a' of the paper tube firework in process 1 and process 2 of a single detection process can be the same or different.

[0062] The above-mentioned photo-taking process can also arrange process 3 as step 1, followed by processes 1 and 2. In addition, for the implementation of processes 1 and 2, only one process can be selected to be executed. These changes in the process can be achieved through program adjustments, which will not be elaborated here.

[0063] See Figure 15 The main imaging and detection device 310 and the auxiliary imaging and detection device 311 in the imaging and detection assembly 3 each include a housing 312, two vertically arranged positioning cameras 313, and two detection cameras 314 located between the two positioning cameras 313. The positioning cameras 313 use wide-angle lenses to capture images of the paper tube opening and positioning that are close to the camera, and the shooting range is large. The detection cameras 314 use non-wide-angle lenses to capture images of the inside of the paper tube that is far from the camera and only capture images of the lead wire to be detected. The two detection cameras 314 have different shooting focal lengths. By selecting detection cameras 314 with different focal lengths, it is possible to adapt to the shooting of paper tube fireworks of different sizes and specifications.

[0064] The vertical arrangement of the two positioning cameras 313 and the detection camera 314 in the main image detection device 310 and the auxiliary image detection device 311 can adapt to different movement paths. When moving upward, the upper positioning camera 313 and the middle detection camera 314 can be used for operation. When moving downward, the lower positioning camera 313 and the middle detection camera 314 can be used for operation.

[0065] During the photo taking process, under the control of the main control system, when the paper tube firework sphere tilts and deforms, the main photo detection device 310 and the auxiliary photo detection device 311 can... Figure 16 The arrow path shown only takes pictures of the two rows of paper tubes on both sides of the paper tube firework projectile as they move upwards or downwards one by one (the leads inside the paper tubes on both sides may overlap in the deformed state); when moving upwards or downwards to take pictures, the positioning camera 313 takes a picture first, the system's vision processing software finds the center position of the paper tube, and then transmits this data to the main control system. The main control system then controls the picture detection device to move to the center position of the paper tube so that the detection camera 314 can take a precise picture [see...]. Figure 16 [(a), (b)]; When the paper tube firework is not deformed, the method of taking a picture is as follows: Figure 16 As shown in (c), start by taking pictures of each paper tube from the bottom up, starting from the outermost column of the paper tube fireworks. After reaching the top paper tube, move horizontally to the adjacent paper tube and then take pictures from top to bottom.

[0066] The above-described embodiment of the shooting method is only one shooting mode; other implementation methods include, but are not limited to: (1) The detection camera 314 can be one or more, or it can be a zoom camera.

[0067] (2) The positioning camera 313 can also be placed separately outside the photo detection device to take panoramic photos of the detection object. The system's visual processing software can find the center position of all paper tubes at once.

[0068] (3) There can be one or more photographic detection devices. For example, a zoom camera can be used to take a picture of the paper tube opening of the paper tube firework, and then the focus can be adjusted to take a picture of the inside of each paper tube.

[0069] (4) The horizontal motion module can be selected according to the actual production needs. For example, if only paper tube fireworks of the same size are transported each time, only one set of horizontal motion module can be used.

[0070] (5) The image data of the position of each paper tube opening can be obtained by the positioning camera 313 of the photo detection device by taking pictures of the paper tubes of the paper tube firework at the same time, or by taking pictures of the paper tubes of the paper tube firework one by one.
