Description

TECHNICAL FIELD

[0001] The technical scheme relates to the technical field of detection equipment, and particularly relates to a detection device suitable for cosmetic pen barrels. BACKGROUND

[0002] The detection device is a device or instrument for testing or measuring certain properties of an object, which measures relevant data on the object directly or indirectly and feeds back the information to a related system or user for analysis, judgment and control.

[0003] The existing cosmetic pen barrels are often designed with various identification information, texture patterns or other designs on the outer peripheral wall. After the cosmetic pen barrels are put into mass production, problems such as outer wall damage, dirt, scratches and material defects may occur in the production process. Therefore, these products with defects need to be screened in the subsequent production detection process.

[0004] The current detection method needs to manually identify a large number of cosmetic pen barrels one by one, which is low in identification efficiency and has a very large overall workload. In addition, manual detection is prone to errors in a long time, which may result in insufficient product quality and reduce the excellent rate of products, and the detection efficiency is poor and needs to be improved.

[0020] The sliding driving member is used to drive the sliding table to slide, so that the driving rubber wheel can be close to and abut against the driven rubber wheel to form a friction transmission; when the material rotating motor drives the driving rubber wheel to rotate, the driven rubber wheel is driven to rotate to realize the rotation of the pen barrel.

[0021] Through the above technical solution, the sliding driving member drives the sliding table to move up and down along the predetermined track on the material rotating frame; when the sliding table moves downward, it is close to the material positioning assembly at the detection station; based on the alignment of the projection of the driving rubber wheel along the sliding direction of the sliding table with the position of the driven rubber wheel, the driving rubber wheel is accurately abutted against the driven rubber wheel at the end of the needle holder, a certain elastic deformation occurs to ensure the close abutment between the rubber wheels, increase the friction, and form a close friction transmission after contact; the driving rubber wheel is driven to rotate by the material rotating motor to drive the driven rubber wheel to rotate, and then drive the needle holder and the needle connected with the driven rubber wheel to rotate, realize the stable rotation of the pen barrel, ensure the accuracy and stability of the rotation of the pen barrel, simplify the transmission structure, and improve the efficiency and reliability of the whole material rotating process.

[0023] The feeding push rod extends forward along the sliding direction of the feeding sliding block, and the feeding driving member is used to drive the feeding sliding block to slide, so that the feeding push rod pushes the pen barrel on the conveying mechanism and is sleeved on the needle.

[0024] Through the above technical solution, the feeding driving member drives the feeding sliding block to move along the feeding frame, and the feeding push rod also moves correspondingly with the feeding sliding block; when the feeding push rod, the pen barrel on the conveying mechanism, and the needle at the feeding station are in the same axial position, the feeding push rod pushes the pen barrel to accurately guide and sleeve on the needle, and after the feeding action is completed, the feeding push rod is reversely retreated to the initial position, so as to ensure the accurate and efficient feeding of the pen barrel, and the automatic mode reduces the difficulty and intensity of manual operation, thereby improving the production efficiency.

Then, the clamping motor drives the two ejection claws to move close to each other until the two pushing parts are tightly supported on the side end face of the pen barrel in the direction of being sleeved into the needle. During the movement of the blanking clamp to the second position, the pushing parts push the pen barrel out of the needle, so that the pen barrel moves stably to the conveying mechanism. After the blanking action is completed, the two ejection claws are opened, and the blanking clamp is reversely retreated to the initial position. The pen barrel is accurately and efficiently blanked. The automatic mode further improves the production efficiency.

[0029] Preferably, the pushing part is provided with a giving slot, and the two giving slots are arranged on opposite sides of the two pushing parts, respectively, and the two giving slots are spliced to form a giving cavity for accommodating the needle.

[0030] Through the above technical solution, based on the fact that the pushing part is provided with a giving slot, the two giving slots of the two pushing parts are opposite to each other. When the two ejection claws move close to each other, the two giving slots are spliced together to form a complete giving cavity for accommodating the needle.

The recording device is connected to the upper computer in real time, and the data of each shooting is uploaded to the upper computer. The upper computer (PC computer) splices the pictures taken by multiple continuous shootings to form a complete appearance image of the pen barrel. Then, the image is compared with the previously archived picture, and based on the image processing algorithm, it is determined whether the pattern or concave-convex texture on the pen barrel meets the requirements according to the comparison result. If not, an early warning is given to prompt the operator to check or handle. The intelligent processing mode reduces the degree of manual intervention and improves the automation level of the whole production line.

[0034] Preferably, the conveying mechanism comprises a conveying assembly one and a conveying assembly two for conveying the pen barrel, the conveying assembly one is connected to the feeding station of the feeding assembly at the terminal end of the conveying direction, and the conveying assembly two is connected to the discharging station of the discharging assembly at the starting end of the conveying direction.

The disc driving member drives the second disc to rotate through the cam divider. The cam divider can control the rotation angle of the second disc, so as to drive the material positioning assembly to switch between different stations in sequence.

[0038] Through the technical scheme, the cam divider is arranged on the disc driving member. The cam divider receives the rotary power from the disc driving member and converts the power into the accurate rotation of the second disc according to the preset division ratio or angle. The rotation angle of the second disc is controlled according to the preset angle parameter, so as to ensure the accurate switching of the material positioning assembly between stations. Since the first disc is fixedly arranged, the position of the material rotating assembly is fixed and unchanged, but different material rotating assemblies can be accessed through the overall rotation of the second disc, thereby improving the efficiency and accuracy of the whole system.

[0039] Preferably, the plurality of material positioning assemblies are circumferentially distributed around the rotation axis of the second rotary disc.

[0040] By the above technical solution, the number of material positioning assemblies is increased, more pen barrels can be processed at the same time, and operations such as feeding, discharging, and detection are performed respectively, so that more detection tasks can be completed in a shorter time.

[0062] Referring to Figure 6 The feeding assembly 6 includes a feeding frame 61, a feeding driving member 62, a feeding sliding block 63, and a feeding push rod 64. The feeding frame 61 is installed on the machine base 1. The feeding sliding block 63 is slidingly arranged at the upper end of the feeding frame 61 through a sliding rail structure. The sliding direction is horizontally arranged and parallel to the length direction of the pen barrel 100 conveyed by the conveying assembly 31. The feeding push rod 64 is located at the lower end of one side of the feeding sliding block 63 and extends towards the feeding direction of the pen barrel 100. The feeding driving member 62 is preferably a cylinder and is installed on the feeding frame 61. In the initial state, the feeding sliding block 63 is away from the conveying assembly 31.

After feeding, it is reset and the feeding operation is repeated.

[0063] Referring to Figure 2 and Figure 3 The pen barrel 100 detection module 2 includes a mounting frame 201, a camera cover 202, and a camera recorder 203. The mounting frame 201 is erected on the machine base 1 and is fixedly installed with the machine base 1. In this embodiment, the mounting frame 201 is composed of a plurality of rods, so that the camera cover 202 can be sleeved on the plurality of rods and fixedly installed with the mounting frame 201, and the position is located at the middle part relative to the mounting frame 201. The camera recorder 203 is located above the camera cover 202 and is fixedly installed with the mounting frame 201. The camera cover 202 has a camera channel 13, which is formed on the upper end surface of the camera cover 202. The camera head at the lower end of the camera recorder 203 is aligned with the camera channel 13.

[0064] Referring to Figure 4 and Figure 5The disc assembly 4 is further provided with a material rotating mechanism 8. The material rotating mechanism 8 comprises a material rotating frame 81, a sliding driving element 82 and a material rotating assembly 83.

The material rotating assembly 83 comprises a sliding table 831, a material rotating motor 832 and a driving rubber wheel 833. The sliding table 831 is slidably connected to the material rotating frame 81 and slides vertically. The material rotating motor 832 is installed on the sliding table 831. The driving rubber wheel 833 is arranged on the driving shaft of the material rotating motor 832. The material rotating motor 832 can drive the driving rubber wheel 833 to rotate.

[0065] When one of the material positioning assemblies 5 is in the detection station, the position of the material positioning assembly 5 is close to the pen barrel 100 detection module 2. The pen barrel 100 on the material positioning assembly 5 is just below the recording cover 202. The length direction of the pen barrel 100 is arranged corresponding to the recording channel 13. The projection of the driving rubber wheel 833 along the sliding direction of the sliding table 831 is aligned with the position of the driven rubber wheel 11. After the sliding driving element 82 drives the sliding table 831 to slide downward, the driving rubber wheel 833 is close to and abuts on the driven rubber wheel 11 to form a friction transmission. The rotation axis of the driving rubber wheel 833 is parallel to the rotation axis of the needle holder 521.

[0066] The driving rubber wheel 833 is driven to rotate by the material rotating motor 832. The driving rubber wheel 833 drives the driven rubber wheel 11 to rotate through the friction force of the outer peripheral wall contact. The driven rubber wheel 11 drives the synchronous needle holder 521 to rotate, and then drives the pen barrel 100 on the needle 52 to rotate synchronously. The rotation arc of the pen barrel 100 corresponds to the width of the recording channel 13. The pen barrel 100 rotates by a certain angle, and the camera 203 controls the camera to take a picture correspondingly. Until the pen barrel 100 rotates at least one circle, the camera records the appearance image of the pen barrel 100 completely. The camera 203 is connected to the host computer in real time, and the data of each picture is uploaded to the host computer. The host computer (PC computer) splices the pictures taken continuously to form a complete appearance image of the pen barrel 100. Then, the appearance image is compared with the previously archived picture. According to the comparison result, whether the pattern or the concave-convex texture and other detail features on the pen barrel 100 meet the requirements is judged through the image processing algorithm. If the requirements are met, the device operates normally. If the requirements are not met, the device immediately gives a warning and prompts the operator to check or handle.

[0067] Referring to Figure 7 and Figure 8The blanking assembly 7 comprises a blanking frame 71, a blanking driving member 72, a blanking sliding block 73 and a blanking clamp 74. The blanking frame 71 is installed on the base 1. The blanking sliding block 73 is slidingly arranged at the upper end of the blanking frame 71 through a sliding rail structure. The sliding direction is horizontally arranged and parallel to the length direction of the pen barrel 100 conveyed on the conveying assembly two 32. The blanking driving member 72 is preferably a cylinder which is installed on the blanking frame 71. The blanking clamp 74 is located at the lower end of one side of the blanking sliding block 73. The blanking clamp 74 comprises a clamping motor 741 and two stripping claws 742. The two stripping claws 742 are located at the side of the clamping motor 741 away from the blanking sliding block 73. The clamping motor 741 drives the two stripping claws 742 to move towards each other, move away from each other or move close to each other. Each stripping claw 742 comprises an extension part 7421 and a pushing part 7422. The pushing part 7422 is arranged at the end of the extension part 7421 away from the clamping motor 741. The two pushing parts 7422 on the two sides are correspondingly curved. Each pushing part 7422 has a displacement slot 12. The two displacement slots 12 are correspondingly arranged on the opposite sides of the two pushing parts 7422. The two displacement slots 12 are spliced to form a space for accommodating the ejector pin 52.

[0068] The blanking driving member 72 is used to drive the blanking sliding block 73 to slide so that the blanking clamp 74 moves between the first position and the second position. When the blanking clamp 74 is in the second position, it is in an open state and the two stripping claws 742 are away from each other. The blanking driving member 72 drives the blanking sliding block 73 to move close to the positioning assembly 5 in the feeding station. At this time, the blanking clamp 74 is in the first position, so that the pen barrel 100 on the positioning assembly is between the two extension parts 7421. The clamping motor 741 drives the two stripping claws 742 to move close to each other, so that the two pushing parts 7422 are supported on the side end face of the pen barrel 100 in the direction of being sleeved into the ejector pin 52. The ejector pin 52 is located in the two displacement slots 12.
