Description

Technical Field

[0001] This utility model relates to the field of atomization detection machine technology, and in particular to a vision-based atomization press head detection machine. Background Technology

[0002] Atomizing pump heads are widely used in various daily chemical products, pharmaceutical products, and other fields requiring spraying. The quality of the atomizing pump head directly affects the product's effectiveness and user experience. Therefore, during the production process, spray testing of the atomizing pump head is necessary to ensure its performance meets standards.

[0003] Traditional methods for detecting atomized pump heads rely primarily on manual inspection, which is inefficient and prone to misjudgments. Furthermore, some semi-automated inspection equipment suffers from slow speeds, low levels of automation, and insufficient accuracy. These traditional methods struggle to meet the ever-increasing demands for efficiency and quality in modern industrial production.

[0004] For example, existing testing devices typically require manual placement of the atomizing nozzle at the testing station, followed by air or water pressure to drive the spray, with manual observation of the spray's shape, angle, and uniformity. This method is not only inefficient but also highly susceptible to human error, making it difficult to guarantee consistency and objectivity. Alternatively, some devices employ simple mechanical structures for automatic feeding and unloading, but the testing process still relies on manual observation, failing to achieve fully automated testing.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully automatic, efficient, and fast vision-based atomization press head detection machine.

[0007] This utility model is achieved through the following technical solution: To solve the above-mentioned technical problems, this utility model provides a vision-based atomizing press head inspection machine, including a frame, a turntable rotatably connected to the frame, and a rotation drive device for driving the turntable to rotate. The turntable has a press head feeding mechanism, a testing area, a waste discharge mechanism, and a discharge mechanism sequentially arranged on its side. The testing area is equipped with a first vision inspection module for detecting the spray quality of the atomizing press head. Multiple fixtures for clamping the press heads are evenly arranged around the periphery of the turntable. A water injection structure is provided on the turntable. The device includes a lifting water pipe located below each of the aforementioned fixtures and capable of being inserted into the fixtures from bottom to top and connecting with the pressing head. The lifting water pipe is used to inject water into the pressing head and push the pressing head upward to make it spray. The lifting water pipe is slidably connected to the turntable in the vertical direction and can rotate synchronously with the turntable. A lifting drive mechanism for driving the lifting water pipe to move up and down is provided between the lifting water pipe and the frame. A pressurized water pump is also provided on the turntable. A water supply pipe connecting the pressurized water pump and the lifting water pipe is provided between the two. A solenoid valve is provided on the water supply pipe.

[0008] To further address the technical problems addressed by this invention, a vision-based atomizing press head testing machine is provided. The lifting drive mechanism includes a roller located at the lower end of a lifting water pipe and a guide rail encircling the frame and positioned below the lifting water pipe. The roller abuts against the upper surface of the guide rail from top to bottom and can roll along it. The upper surface of the guide rail is undulating and includes at least a high surface area and a low surface area. The position of the high surface area corresponds to the test area, so that the lifting water pipe lifts the press head in the test area.

[0009] To further address the technical problems to be solved by this utility model, this utility model provides a vision-based atomizing press head detection machine, wherein a second vision detection module for detecting whether a press head exists in the corresponding tooling is provided between the downstream of the press head feeding mechanism and the upstream of the test area.

[0010] To further address the technical problems addressed by this invention, a vision-based atomizing press head testing machine is provided.

The first interface has an inlet pipe leading to a pressurized water pump; the second interface has a drain pipe with a drain check valve; and the third interface has an inlet pipe leading to a corresponding lifting water pipe. Furthermore, the solenoid valve can switch between a test state and a drainage state. In the test state, the first and third interfaces are activated to supply water to the lifting water pipe; in the drainage state, the second and third interfaces are activated to utilize the siphon effect for drainage.

[0011] To further solve the technical problem to be solved by this utility model, this utility model provides a vision-based atomizing press head inspection machine, wherein the tooling includes a bottom through hole for the lifting water pipe to pass through, a side notch provided above the bottom through hole and opening outward, and a baffle provided above the side notch for restricting the axial movement of the press head, wherein the shape and size of the side notch are adapted to the shape and size of the press head.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 7 As shown, this utility model provides a vision-based atomizing pump head testing machine for automatically detecting the spray quality of the atomizing pump head. Its main components include a frame 1, a turntable 2, a rotary drive device 21, an atomizing pump head feeding mechanism 3, a testing area 4, a waste material discharge mechanism 5, a feeding mechanism 6, and a water injection structure 7.

[0022] The frame 1 is the supporting structure of the entire testing machine, and all other components are mounted on it. The turntable 2 is rotatably connected to the frame 1 via bearings or other means, enabling intermittent or continuous rotational motion. The rotary drive device 21 is used to drive the turntable 2 to rotate, and it is preferably a motor plus a transmission mechanism, such as a stepper motor with a reducer or a direct-drive shaft, to achieve precise control of the rotation angle and speed of the turntable 2. By precisely controlling the rotation of the turntable, the fixture 22 can be sequentially sent to different workstations to complete steps such as loading, testing, and unloading.

[0023] The turntable 2 has, in sequence, a misting press head feeding mechanism 3, a testing area 4, a waste discharge mechanism 5, and a unloading mechanism 6 arranged on its side. The misting press head feeding mechanism 3 is used to automatically place the misting press head to be tested into the fixture 22, preferably including a vibratory plate; the testing area 4 is the area for spray testing; the waste discharge mechanism 5 is used to remove the unqualified misting press head from the fixture 22; and the unloading mechanism 6 is used to remove the qualified misting press head from the fixture 22.

[0024] In test area 4, a first visual inspection module 41 is provided for detecting the spray quality of the atomizing pump head. This first visual inspection module 41 may include an industrial camera, a light source, and an image processing system. The industrial camera is used to capture images of the spraying from the atomizing pump head, the light source provides stable illumination, and the image processing system analyzes the images to determine the shape, angle, uniformity, and presence of defects such as clogging. The image processing system can employ various image processing algorithms, such as edge detection, morphological processing, and pattern recognition, to achieve accurate evaluation of the spray quality.

[0025] Multiple fixtures 22 for clamping the atomizing press head are evenly arranged around the periphery of the turntable 2. Each fixture 22 is designed to securely clamp the atomizing press head and facilitate the insertion of the lifting water pipe 71 and observation of the spray.

[0026] The water injection structure 7 is a key component of this utility model, which includes a lifting water pipe 71, a lifting drive mechanism 72, a pressurized water pump 73, a water delivery pipe (including 7411 and 7431), and a solenoid valve 74. Figure 6 As shown, the lifting water pipe 71 is located below each fixture 22, allowing it to be inserted into the fixture 22 from bottom to top and connect with the atomizing press head. The function of the lifting water pipe 71 is to inject water at a certain pressure into the atomizing press head, while simultaneously pushing the atomizing press head upwards to generate a spray. The lifting water pipe 71 is slidably connected to the turntable 2 in the vertical direction and can rotate synchronously with the turntable 2. Thus, when the turntable 2 rotates, the lifting water pipe 71 also rotates, ensuring that it remains below the fixture 22 at all times.

[0027] The lifting drive mechanism 72 is used to drive the lifting water pipe 71 to rise and fall. In this embodiment, the lifting drive mechanism 72 includes a roller 721 located at the lower end of the lifting water pipe 71 and a guide rail 722 arranged on the frame 1 and located below the lifting water pipe 71. The roller 721 abuts against the upper surface of the guide rail 722 from top to bottom and can roll along it. The upper surface of the guide rail 722 is undulating, including at least a high surface area 7221 and a low surface area 7222. The position of the high surface area 7221 corresponds to the position of the test area 4, so that the lifting water pipe 71 lifts the atomizing press head in the test area 4 for spray testing. When the roller 721 rolls in the low surface area 7222, the lifting water pipe 71 descends and separates from the atomizing press head, facilitating loading and unloading.

[0028] A pressurized water pump 73 is mounted on the turntable 2 to provide pressurized water for spraying. A water supply pipe connects the pressurized water pump 73 and the lifting water pipe 71, delivering pressurized water to the lifting water pipe 71. A solenoid valve 74 is mounted on the water supply pipe to control the timing and flow rate of water supplied to the lifting water pipe 71.

[0029] To further improve detection efficiency and reliability, this utility model also includes the following optimized designs: Downstream of the atomizing press head feeding mechanism 3 and upstream of the test area 4, a second vision detection module 42 is provided to detect whether an atomizing press head is present in the corresponding fixture 22. This second vision detection module 42 can prevent water injection tests from being performed when there is no atomizing press head in the fixture 22, thus avoiding waste of water resources and cleaning fluid.

[0030] like Figure 7 As shown, the solenoid valve 74 has three interfaces: a first interface 741, a second interface 742, and a third interface 743. The first interface 741 has an inlet pipe 7411 leading to the pressurized water pump 73; the second interface 742 has a drain pipe 7421 with a drain check valve 7422; and the third interface 743 has an inlet pipe 7431 leading to the corresponding riser water pipe 71. The solenoid valve 74 can switch between a test state and a drain state.

[0031] In the test state, the solenoid valve 74 connects the first interface 741 and the third interface 743, thereby supplying water to the riser water pipe 71.

[0032] In the draining state, the solenoid valve 74 connects the second interface 742 and the third interface 743, that is, the drain pipe 7421 and the lifting water pipe 71 are connected. Since the drain pipe 7421 is in a low position, a siphon effect will be generated to drain the lifting water pipe 71 and the residual water in the product. The main purpose is to remove the residual moisture in the product and prevent the formation of spots and watermarks after the product dries.

[0033] like Figure 5As shown, the fixture 22 includes a bottom through hole 221, a side notch 222, and a baffle 223. The bottom through hole 221 allows the lifting water pipe 71 to pass through. The side notch 222 is located above the bottom through hole 221 and faces outwards, facilitating the placement and removal of the atomizing pump head. The shape and size of the side notch 222 are adapted to the shape and size of the atomizing pump head to achieve a stable clamping of the atomizing pump head. The baffle 223 is located above the side notch 222 to restrict the axial movement of the atomizing pump head.

[0034] The booster pump 73 is equipped with a rotary joint (not shown in the figure) and a water distribution plate 75. The rotary joint is used to ensure that the booster pump 73 can continuously supply water during rotation. The water distribution plate 75 is equipped with multiple water outlets 751, and each water outlet 751 is connected to the corresponding solenoid valve 74 through a water pipe, which is used to distribute the water flow output by the booster pump 73 to each solenoid valve 74.

[0035] Test area 4 is equipped with a baffle plate 43 to block the water mist generated by the spray and prevent it from splashing out and polluting the environment. A return water tank 44 is located on the outside of the baffle plate 43 to collect the water mist blocked by the baffle plate 43. The input end of the pressurized water pump 73 and the return water tank 44 are connected by a water pipe to form a water recycling system, saving water resources.

[0036] The waste discharge mechanism 5 includes a blowing device 51 and a discharge chute 52 inclined on the side of the turntable 2. The blowing device 51 may be a cylinder-driven jet nozzle used to blow out the defective atomizing press heads from the tooling 22. The discharge chute 52 is used to collect the blown-out defective atomizing press heads and guide them to a designated waste bin.

[0037] The feeding mechanism 6 includes a feeding track 61. The inner end of the feeding track 61 extends toward the corresponding tooling 22 and can guide qualified atomizing pressing heads in the corresponding tooling 22 to transfer to the feeding track 61. The feeding track 61 can be an inclined slide, using gravity to automatically slide qualified atomizing pressing heads into a designated collection box.

[0038] The working principle of this utility model: During operation, the atomizing press head to be tested is first automatically placed into the fixture 22 by the atomizing press head feeding mechanism 3. Then, the rotary drive device 21 drives the turntable 2 to rotate, sequentially delivering the fixture 22 containing the atomizing press head to each workstation. When the fixture 22 reaches the test area 4, the lifting drive mechanism 72 drives the lifting water pipe 71 to rise, connect with the atomizing press head, and lift it up. At the same time, the solenoid valve 74 switches to the test state, and the pressurized water pump 73 delivers pressurized water through the water supply pipe to the lifting water pipe 71, causing the atomizing press head to produce a spray. The first vision detection module 41 photographs and analyzes the spray to determine whether its quality is qualified. If the spray is qualified, the turntable 2 continues to rotate, sending the fixture 22 to the unloading mechanism 6, which removes the qualified atomizing press head. If the spray is unqualified, the turntable 2 rotates, sending the fixture 22 to the waste discharge mechanism 5, which blows out the unqualified atomizing press head. This process is repeated to achieve fully automatic detection of the atomizing pump head.

[0039] This invention achieves efficient and accurate detection of atomizing press heads by employing visual inspection technology and automated control technology, thereby improving production efficiency and product quality.

[0040] The above is a detailed description of the specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any modifications and improvements made based on the design concept of this utility model should be included within the protection scope of this utility model.
