Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a calibration mechanism for the marking surface of a mold. Background Technology

[0002] Laser marking is mainly divided into two types: engraving and dot matrix, and is widely used in many fields. It mainly achieves permanent marking of information such as production date, batch number, anti-counterfeiting, and anti-counterfeiting. At the same time, it adopts high photoelectric conversion efficiency, low cost operation, no need to use ink or solvent, avoids the tedious process of daily maintenance, and has the advantages of clear marking and not easy to fall off.

[0003] However, for some molds with front and back sides, there is still a probability that the coding side will be reversed during the actual coding process. This results in the coding not being processed according to the actual requirements, which not only makes the mold itself lose its marking effect, but also makes it difficult to detect when multiple molds are mixed together. This can lead to non-compliant products entering the market, potentially causing economic or reputational losses. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a novel calibration mechanism for the marking surface of molds.

[0005] To achieve the above objectives, the solution adopted by this utility model is as follows:

[0006] A calibration mechanism for the marking surface of a mold is located on a transmission path. The calibration mechanism includes a vision inspection unit located at the calibration station, a front interception module and a rear interception module located at the front and rear ends of the calibration station, and a clamping and flipping unit located at the calibration station. The clamping and flipping unit includes a gripper for clamping a single mold, a flipping component that drives the gripper to flip in 180° cycles, and a lifting component that drives the gripper and the flipping component to rise and fall synchronously. With the interaction of the front interception module and the rear interception module, each mold passes through the calibration station one by one, and the vision inspection unit detects and obtains the top surface information of the mold. Based on the top surface information, the clamping and flipping unit either lifts and flips the mold or releases the mold to keep the marking surface facing upwards as it enters the marking station.

[0007] Preferably, the visual inspection unit includes a visual camera located above the transmission path, a lamp for supplemental lighting, and an image processor, wherein the image processor can identify information about the coded surface based on the photographic information captured by the visual camera. Supplemental lighting based on the lamps allows for higher quality acquisition of end-face information and reduces the error rate in judgment.

[0008] Furthermore, a vertically extending support pole is provided on one side of the transmission path, on which the vision camera and the lighting fixture can be slidably mounted. The vision camera and the lighting fixture are staggered front to back. This staggered arrangement of the vision camera and the lighting fixture avoids imaging interference between them; at the same time, the vertical adjustment meets the needs of supplementary lighting and photography in actual working conditions, thereby more accurately acquiring end-face image information.

[0009] According to a specific embodiment and preferred aspect of this utility model, the lifting component and the flipping component can move synchronously. Because lifting is necessary to perform the flipping operation, synchronous movement of both components can shorten the flipping time and improve calibration efficiency.

[0010] According to another specific embodiment and preferred aspect of the present invention, the flipping assembly includes a flipping seat and a flipping power unit, wherein the flipping seat rotates around the width of the transmission path, the flipping power unit is used to drive the flipping seat to flip with a flipping cycle of 180°, and the gripper is mounted on the flipping seat.

[0011] Preferably, a clamping rail is provided on the flipping seat, and the jaws slide towards each other on the clamping rail to form a moving clamp.

[0012] According to another specific embodiment and preferred aspect of the present invention, the gripper includes two symmetrically arranged first gripping arms and second gripping arms, wherein the first gripping arms form V-shaped or U-shaped clamping walls, and when the first gripping arms and second gripping arms clamp, the mold is located between the two clamping walls.

[0013] Preferably, the two clamping walls are spaced apart to accommodate molds with different outer diameters. Furthermore, the thickness of the first and second clamping arms is less than the height of the mold, and they clamp the mold in the middle. This allows for flipping within a smaller space.

[0014] Furthermore, the front and rear interception modules have identical structures and are located on opposite sides of the relative transmission path. Specifically, both the front and rear interception modules include a mold base, a sliding mold slidably mounted on the mold base, and a blocking rod formed on the sliding mold and extending into the transmission path to block the mold's forward movement. That is, blocking and release are achieved through the extension and retraction of the blocking rod.

[0015] Due to the application of the above-mentioned technology and equipment solutions, this utility model has the following advantages compared with the prior art:

[0016] For existing molds with front and back sides, there is still a probability of the coding surface being reversed during the actual coding process. This results in coding not being performed according to the actual requirements, which not only renders the mold itself ineffective but also makes it difficult to detect when multiple molds are mixed together, leading to non-compliant products entering the market and potentially causing economic or reputational losses. This utility model addresses these shortcomings by comprehensively designing a calibration mechanism for the mold coding surface. Using this calibration mechanism, firstly, the molds are sequentially passed through calibration stations by front and rear interception modules; secondly, based on visual... The current end face information is detected and compared with the coding face. Finally, based on the comparison result, the mold is released directly or clamped and lifted and rotated 180° to bring the coding face of the mold into the coding station, thus completing the calibration of the coding face of the mold. Therefore, this utility model adopts a sorting and inspection method to complete the calibration of the coding face of each mold. Once an inversion occurs, it is lifted and rotated 180° before being placed on the transmission path to avoid the coding face being inverted, ensuring the accuracy of product marking, reducing the probability of non-compliant products flowing into the market, and also reducing the risk of economic or reputational damage.

[0032] like Figures 1 to 4 As shown, the calibration mechanism for the marking surface of the mold in this embodiment is located on the transmission path, and the calibration mechanism includes a visual inspection unit 1 located at the calibration station, a front interception module 2 and a rear interception module 3 located at the front and rear ends of the calibration station, and a clamping and flipping unit 4 located at the calibration station.

[0033] In some specific embodiments, the visual inspection unit 1 includes a visual camera 10 located above the transmission path, a lamp 11 for supplementary lighting, and an image processor, wherein the image processor can identify information about the coded surface based on the photographic information captured by the visual camera 10. Supplementary lighting from the lamp 11 allows for higher quality acquisition of end-face information and reduces the error rate in judgment. In this example, the lamp 11 is an LED light.

[0034] In this example, a vertically extending support pole 5 is provided on one side of the transmission path. The vision camera 10 and the lamp 11 are mounted on the support pole 5, which can slide vertically. The vision camera 10 and the lamp 11 are staggered front to back. The staggered arrangement of the vision camera and the lamp avoids imaging interference. At the same time, the vertical adjustment meets the needs of supplementary lighting and photography in actual working conditions, and further accurately obtains information from the end face photograph.

[0035] The front interception module 2 and the rear interception module 3 have the same structure and are located on opposite sides of the relative transmission path. Specifically, both the front interception module 2 and the rear interception module 3 include a mold base m, a sliding mold h slidably mounted on the mold base m, and a blocking rod d formed on the sliding mold h and extending into the transmission path to block the mold B from moving forward. That is, blocking and release are achieved by extending and retracting the blocking rod d.

[0036] In some specific embodiments, the clamping and flipping unit 4 includes a gripper 40 for clamping a single mold B, a flipping component 41 that drives the gripper 40 to flip in 180° cycles, and a lifting component 42 that drives the gripper 40 and the flipping component 41 to rise and fall synchronously. Under the interaction of the front intercepting module 2 and the rear intercepting module 3, each mold B passes through the calibration station one by one, and the top surface information of the mold is obtained by the vision inspection unit 1. Based on the top surface information, the clamping and flipping unit 4 lifts and flips or releases the mold to keep the coding surface of the mold B facing upwards as it enters the coding station.

[0037] In this example, the lifting assembly 42 and the flipping assembly 41 can move synchronously. This is because lifting is necessary for the flipping operation, and synchronous movement shortens the flipping time and improves calibration efficiency. Specifically, the flipping assembly 41 includes a flipping base 410 and a flipping power unit 411. The flipping base 410 rotates around the width of the transmission path, and the flipping power unit 411 drives the flipping base to flip in 180° cycles. Grippers 40 are mounted on the flipping base 410. A clamping rail g is provided on the flipping base 410, and the grippers 40 slide towards each other on the clamping rail g to form a moving clamp. Each gripper 40 includes two symmetrically arranged first clamping arms 401 and second clamping arms 402. The first clamping arms 401 form V-shaped clamping walls. When the first clamping arms 401 and second clamping arms 402 clamp, the mold B is located between the two clamping walls, which are spaced apart to accommodate molds of different outer diameters.

[0038] Furthermore, the thickness of the first clamping arm 401 and the second clamping arm 402 is less than the height of the mold B, and they are clamped in the middle of the mold B. This allows for flipping to be performed in a smaller space.

[0039] The lifting assembly 42 is a commonly used lifting cylinder, but other lifting methods can also be used instead, such as hydraulic cylinders, electric cylinders, etc.

[0040] In summary, after adopting the calibration mechanism for the coding surface of this mold, firstly, the molds are passed through the calibration station one by one based on the front and rear interception modules; secondly, the current end face information is obtained based on visual detection and compared with the coding surface; finally, based on the comparison result, the mold is directly released or clamped and lifted and rotated 180° to ensure that the coding surface of the mold enters the coding station facing upwards, thus completing the calibration of the coding surface of the mold. Therefore, this utility model, on the one hand, adopts a sorting and inspection method to complete the calibration of the coding surface of each mold. If an inversion occurs, it is lifted and rotated 180° before being placed on the transmission path to avoid the coding surface being inverted, ensuring the accuracy of product marking, reducing the probability of non-compliant products flowing into the market, and also reducing the risk of potential economic or reputational losses; on the other hand, it is based on the supplementary lighting of the lamps to... Higher quality end-face information acquisition reduces judgment error rate; simultaneously, the misalignment of the vision camera and lighting fixtures avoids imaging interference, and the vertical adjustment meets the needs of supplementary lighting and photography in actual working conditions, further accurately acquiring end-face photo information; thirdly, the lifting component and flipping component can move synchronously, because lifting is necessary to perform the flipping operation, and synchronous movement of both can shorten the flipping time and improve calibration efficiency; fourthly, the two clamping walls are V-shaped and spaced apart to accommodate molds with different outer diameters, and the thickness of the first and second clamping arms is less than the height of the mold, clamping it in the middle of the mold, thus enabling flipping in a smaller space; fifthly, the extension and retraction of the blocking rod realizes blocking and release, facilitating the entry and exit of individual molds from the calibration station.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
