Description
Technical Field
[0001] The present technical solution relates to the technical field of detection equipment, and in particular to a detection device suitable for a cosmetic pen holder. Background Art
[0002] A detection device is a device or instrument used to inspect or test certain specific properties of an object. It measures relevant data on the object directly or indirectly and feeds the information back to the relevant system or user for analysis, judgment and control.
[0003] Existing cosmetic pen holders are often designed with various identification information, pattern patterns or other designs on their outer walls. After cosmetic pen holders are put into mass production, problems such as outer wall damage, dirt, scratches, and material shortages may occur during the production process. These defective products need to be screened in subsequent production inspection links.
[0004] At present, the traditional detection method usually involves clamping the cosmetic pen holder and rotating it, or using the rotation of double rollers to drive the cosmetic pen holder under the detection equipment through friction for detection. However, the concentricity of different cosmetic pen holders is not good during rotation, which can easily cause jumping. There is a large deviation in the accuracy of rotational positioning, which reduces the accuracy of detection. In addition, the process of changing the detection model is cumbersome and inefficient, resulting in poor detection results. Summary of the invention
[0005] In order to improve the problem of poor detection effect caused by the clamping or double-roller rotation method of the cosmetic pen holder, the present technical solution provides a detection device suitable for the cosmetic pen holder.
[0006] The purpose of this technical solution is achieved in this way:
[0007] A detection device for a cosmetic pen holder, comprising a base and a pen holder detection module, wherein the pen holder detection module can collect an appearance image of the pen holder when it rotates at least one circle, and further comprising:
[0008] A conveying mechanism, which is mounted on the machine base and is used to convey the pen holder;
[0009] A disc assembly is mounted on the machine base and can be arranged in alignment with a plurality of workstations. The disc assembly is provided with a material fixing assembly for fixing the pen holder. The disc assembly drives the material fixing assembly to move and transport the pen holder from the previous workstation to the next workstation.
[0010] A loading and unloading mechanism, the loading and unloading mechanism comprising a loading assembly for loading the pen holder into the fixing assembly and a unloading assembly for removing the pen holder from the fixing assembly;
[0011] Among them, the material fixing component includes a base and a pin rotatably arranged on the base, the pen shaft is sleeved on the pin through the open end, and the disc component is also provided with a material transfer mechanism. When the pen shaft is at the recording end of the pen shaft detection module, the material transfer component drives the pin to rotate, so that the pen shaft rotates at least one circle to cooperate with the detection of the pen shaft detection module.
[0012] Through the above technical scheme, when a detection device suitable for a cosmetic pen holder is used normally, the material transfer component drives the ejector pin to rotate. Based on the fact that the size of the ejector pin in the material fixing component is adapted to the inner cavity of the pen holder, after the opening end of the pen holder of the feeding component is aligned with the ejector pin and fit into place, the ejector pin can be stably and firmly engaged on the inner wall of the pen holder, thereby enhancing the connection stability between the ejector pin and the pen holder. When rotating, the ejector pin can effectively drive the pen holder to achieve synchronous rotation, thereby improving the stability of the pen holder rotation.
[0013] The conveying mechanism conveys the pen shaft to the position of the disc assembly in succession. When the pen shaft moves to the loading station, the loading assembly pushes one end of the pen shaft so that the opening at the other end of the pen shaft is fitted with the ejector pin to fix the pen shaft on the fixing assembly. The disc assembly drives the pen shaft to move and pass through each station in turn. When the pen shaft moves to the pen shaft detection module and is in the detection station, the pen shaft is driven to rotate for at least one circle through the transfer assembly. The pen shaft detection module collects the appearance image of the pen shaft during the rotation process, and compares the collected results to issue a warning for defective products. When the pen shaft moves to the unloading assembly and is in the unloading station, the unloading assembly takes the pen shaft out of the fixing assembly and places it on the conveying mechanism to complete the detection. The coordination of multiple devices is good to realize the detection operation of the pen shaft.
[0014] Preferably, the ejector includes an ejector seat and an ejector head arranged at the front end of the ejector seat, a plunger portion protrudes from the front end of the ejector seat, and the pen holder is sleeved on the plunger portion;
[0015] A mounting cavity is correspondingly formed inside the plunger portion, and the ejector head is separately arranged in the mounting cavity, and the ejector head has an embedding portion embedded in the mounting cavity;
[0016] The ejector seat is provided with a fastener, and the fastener is pressed against the embedded portion so that the ejector head is fixed in the installation cavity.
[0017] Through the above technical solution, the ejector head is connected to the ejector seat by a fastener to achieve detachable installation. When the fastener is adjusted to be tight against the embedded part, the ejector head is fixedly installed in the installation cavity to improve the stability of use. When the fastener is adjusted to be loosened, the ejector can be removed. The ejector head is thinner than the ejector seat, and the ejector head is guided to be inserted into the pen shaft.
[0018] The material transfer assembly drives the ejector seat to rotate, thereby driving the ejector head to rotate synchronously. By replacing other ejector seats with plunger parts of different sizes, it can be adapted to different pen barrel diameters to improve applicability.
[0019] Preferably, the material transfer mechanism comprises a material transfer rack, a sliding drive member arranged on the material transfer rack, and a material transfer assembly;
[0020] The material transfer assembly comprises a slide table slidably arranged on the material transfer rack, a material transfer motor arranged on the slide table, and an active rubber wheel, the active rubber wheel being rotatably arranged on the driving end of the material transfer motor; a driven rubber wheel is arranged at one end of the ejector seat away from the ejector, and the projection of the active rubber wheel along the sliding direction of the slide table is aligned with the position of the driven rubber wheel;
[0021] The sliding drive member is used to drive the slide table to slide, so that the active rubber wheel can approach and abut against the driven rubber wheel to form a friction transmission. When the material transfer motor drives the active rubber wheel to rotate, it drives the driven rubber wheel to rotate to realize the rotation of the pen shaft.
[0022] Through the above technical scheme, the sliding drive member drives the slide to move up and down along the predetermined track on the material transfer rack. When the slide moves downward, it approaches the material fixing component at the detection station. Based on the projection of the active rubber wheel along the sliding direction of the slide and the position alignment of the driven rubber wheel, the active rubber wheel is driven to be precisely attached to the driven rubber wheel at the end of the ejector pin seat, and a certain elastic deformation occurs to ensure the close fit between the rubber wheels, increase the friction force, and form a tight friction transmission after contact. The active rubber wheel is driven to rotate by the material transfer motor to drive the driven rubber wheel to rotate in coordination, and then drive the ejector pin seat and the ejector connected to the driven rubber wheel to rotate, so as to realize the stable rotation of the pen shaft, ensure the accuracy and stability of the pen shaft rotation, simplify the transmission structure, and improve the efficiency and reliability of the entire material transfer process.
[0023] Preferably, the feeding assembly comprises a feeding frame arranged on the machine base, a feeding driving member arranged on the feeding frame, a feeding slider slidably arranged on the feeding frame, and a feeding push rod arranged on the feeding slider;
[0024] The feeding push rod extends forward along the sliding direction of the feeding slider, and the feeding driving member is used to drive the feeding slider to slide, so that the feeding push rod pushes the pen holder on the conveying mechanism and is sleeved onto the ejector pin.
[0025] Through the above technical scheme, the loading drive member drives the loading slide to move along the loading rack, and the loading push rod also moves accordingly with the loading slide. When the loading push rod, the pen holder on the conveying mechanism, and the ejector pin at the loading station are in the same axial position, the loading push rod pushes the pen holder to accurately guide and insert it onto the ejector pin. After completing the loading action, it returns to the initial position in the reverse direction, ensuring that the pen holder is accurately and efficiently loaded. The automated method reduces the difficulty and intensity of manual operation, thereby improving production efficiency.
[0026] Preferably, the material unloading assembly comprises a material unloading rack arranged on the machine base, a material unloading driving member arranged on the material unloading rack, a material unloading slider slidably arranged on the material unloading rack, and a material unloading fixture arranged on the material unloading slider;
[0027] The unloading fixture includes a clamping motor and two unloading claws moving toward each other, each of the unloading claws includes an extension portion and a pushing portion arranged at the end of the extension portion, and the unloading driving member is used to drive the unloading slider to slide, so that the unloading fixture moves between the first position and the second position;
[0028] When the unloading clamp is in the first position, the pen shaft is located between the two side extension parts, and the clamping motor drives the two stripping claws to move closer, so that the two side pushing parts are supported on one side end face of the pen shaft along the direction of inserting the ejector pin; when the unloading clamp is in the second position, the two side pushing parts cooperate to push the pen shaft from the ejector pin, so that it moves to the conveying mechanism.
[0029] Through the above technical scheme, the unloading driving member drives the unloading slide block to move along the unloading rack, so that the unloading fixture moves between the first position and the second position. In the initial state, the two stripping claws of the unloading fixture are in an open state. After moving the unloading fixture to the first position, the pen holder is just located between the two side extension parts. Subsequently, the clamping motor drives the two side stripping claws to approach each other until the two side pushing parts are tightly supported on one side end face of the pen holder along the direction of inserting the ejector pin. In the process of moving the unloading fixture to the second position, the pushing part pushes the pen holder from the ejector pin, so that it moves smoothly to the conveying mechanism. After completing the unloading action, the two side stripping claws are opened and returned to the initial position in the reverse direction, ensuring that the pen holder is accurately and efficiently unloaded, and the production efficiency is further improved in an automated manner.
[0030] Preferably, each of the pushing parts is provided with a clearance groove, and two of the clearance grooves are arranged one by one on opposite sides of the pushing parts on both sides, and the two clearance grooves are spliced to form a clearance cavity for accommodating the ejector pin.
[0031] Through the above technical solution, based on the fact that the pushing parts are all provided with a clearance groove, the two clearance grooves of the two pushing parts are opposite to each other. When the two stripping claws move toward each other and approach each other, the two clearance grooves will be spliced together to form a complete clearance cavity for accommodating the ejector pin, thereby expanding the pushing surface of the pen shaft and avoiding interference with the ejector pin seat, so that the pen shaft can be smoothly removed from the ejector pin.
[0032] Preferably, the penholder detection module comprises a mounting frame arranged on the base, a camera cover arranged on the mounting frame, and a camera mounted above the camera cover;
[0033] The recording cover has a recording channel, the length direction of which is parallel to the rotation axis of the active rubber wheel. When the pen holder is moved under the recording cover and aligned with the camera, the recording end of the camera takes a picture of the appearance of the pen holder through the recording channel.
[0034] Through the above technical solution, the arc of rotation of the pen shaft corresponds to the width of the recording channel. Every time the pen shaft rotates a certain angle, the camera will control the camera at its lower end to take a picture until the outer circumference of the pen shaft is completely recorded. The camera is connected to the host computer in real time, and the data of each shot is uploaded to the host computer. The host computer (PC computer) splices the pictures taken continuously to form a complete image of the pen shaft appearance. Then, it is compared with the pre-archived pictures. Based on the image processing algorithm, it is judged whether the pattern or concave and convex texture and other detailed features on the pen shaft meet the requirements according to the comparison results. If not, an early warning will be issued immediately to prompt the operator to check or process. The intelligent processing method reduces the degree of manual intervention and improves the automation level of the overall production line.
[0035] Preferably, the conveying mechanism includes a conveying component 1 and a conveying component 2 for conveying the pen shaft, the terminal end of the conveying component 1 along the conveying direction is connected to the loading station of the loading component, and the starting end of the conveying component 2 along the conveying direction is connected to the unloading station of the unloading component.
[0036] Through the above technical scheme, the conveying mechanism includes two transport lines, namely conveying component one and conveying component two, and a conveyor belt structure is usually adopted, wherein the terminal end of conveying component one along the set conveying direction just docks with the loading station of the loading component, which serves to load the pen rod. After the pen rod completes a series of inspections, the pen rod will fall into the starting end of conveying component two, and the pen rod will be transported to the terminal end for collection. The cooperation between conveying component one and conveying component two ensures the stability and continuity of the pen rod in the entire conveying process, thereby improving production efficiency.
[0037] Preferably, the disc assembly comprises a disc driving member, a cam divider arranged on the disc driving member, a first disc fixedly arranged on the cam divider, and a second rotating disc rotatably arranged on the cam divider;
[0038] The material transfer assembly is arranged on the first disc, and the material fixing assembly is arranged on the second disc. The disc driving member drives the second disc to rotate via a cam divider. The cam divider can control the rotation angle of the second disc, so as to drive the material fixing assembly to switch in sequence between different workstations.
[0039] Through the above technical solution, the cam divider is arranged on the disc driving member, and the rotational power from the disc driving member is received through the cam divider, and this power is converted into precise rotation of the second turntable according to a preset division ratio or angle, so that the rotation angle of the second turntable is controlled according to the preset angle parameters, ensuring that it drives the precise switching of the fixed material assembly between various workstations. Since the first disc is fixedly installed, the position of the material transfer assembly is fixed, but different material transfer assemblies can be accessed through the overall rotation of the second turntable, thereby improving the efficiency and accuracy of the entire system.
[0040] Preferably, the metering components are provided in plurality, and the plurality of metering components are distributed circumferentially around the rotation axis of the second turntable.
[0041] Through the above technical solution, the number of material-fixing components is increased, so that more pen holders can be processed at the same time, and operations such as loading, unloading, and testing can be performed separately, so that more testing tasks can be completed in a shorter time.
[0042] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:
[0043] 1. The technical solution includes a base, an ejector seat and an ejector arranged at the front end of the ejector seat through a material setting component. The size of the ejector is adapted to the inner cavity of the pen holder. The pen holder is aligned with the ejector through the open end and is stably and firmly engaged on the pen holder, thereby enhancing the connection stability between the ejector and the pen holder. When the ejector rotates, it can effectively drive the pen holder to achieve synchronous rotation, thereby improving the stability of the pen holder rotation;
[0044] 2. This technical solution is provided with a pen holder detection module, a conveying mechanism, a disc assembly and a loading and unloading mechanism on the machine base. The disc assembly is provided with a fixing assembly. The conveying mechanism conveys the pen holder to the loading station. The loading assembly pushes the loading to the fixing assembly. The disc assembly drives the pen holder to move through each station in turn. When the pen holder is in the detection station, the transfer assembly drives the pen holder to rotate for at least one circle. The pen holder detection module collects the appearance image of the pen holder during the rotation process. After comparing the collected results, a warning is issued for defective products. When the pen holder is in the unloading station, the unloading assembly takes the pen holder out of the fixing assembly and sends it out by the conveying mechanism to complete the detection. The coordination of multiple devices is good, and the detection operation of the pen holder is realized;
[0045] 3. This technical solution achieves improved applicability by installing the ejector separately in the mounting cavity of the ejector seat, fixing the ejector in the mounting cavity by fasteners, and loosening the fasteners to remove the ejector, thereby facilitating replacement of the ejector with other sizes to adapt to different pen holders.

The unloading driving member 72 drives the unloading slide block 73 to approach the fixing component 5 in the loading station. At this time, the unloading clamp 74 is in the first position, so that the pen body 100 on the positioning component is between the extension parts 7421 on both sides, and the clamping motor 741 drives the two stripping claws 742 to move closer, so that the pushing parts 7422 on both sides are supported on one side end face of the pen body 100 along the direction of inserting the ejector pin 52, and the ejector pin 52 is located in the makeshift grooves 12 on both sides. When the unloading clamp 74 moves back to the second position, the pushing parts 7422 on both sides cooperate to push the pen body 100 from the ejector pin 52, so that the pen body 100 falls onto the conveying component 2 32, and the unloading clamp 74 is opened again to prepare for the next unloading operation and repeat the operation.
[0071] The specific working process of this program is as follows:
[0072] The present technical solution conveys the pen holder 100 to the disc assembly 4 through the conveying assembly 31. When the pen holder 100 moves to the loading station, the loading assembly 6 pushes one end of the pen holder 100 through the loading push rod 64, so that the opening at the other end of the pen holder 100 is engaged with the ejector pin 52. The disc assembly 4 drives the pen holder 100 to move to the pen holder 100 detection module 2. At this time, the pen holder 100 is in the detection station. The active rubber wheel 833 in the transfer assembly 83 cooperates with the driven rubber wheel 11 to drive the pen holder 100 to rotate at least one circle. The camera 203 is recorded in the pen holder 10 through the recording channel 13. 0 The collected images, puzzle comparison, and early warning prompts during the rotation process. When the pen body 100 moves to the unloading station, the unloading component 7 takes out the pen body 100 through the unloading fixture 74 and places it on the conveying component 2 32 for delivery to complete the detection. Based on the fact that the size of the ejector pin 52 in the fixing component 5 is adapted to the inner cavity of the pen body 100, the ejector pin 52 can be stably and firmly engaged on the inner wall of the pen body 100, thereby enhancing the connection stability between the ejector pin 52 and the pen body 100. When rotating, the ejector pin 52 can effectively drive the pen body 100 to achieve synchronous rotation, thereby improving the rotation stability of the pen body 100.
