Description

Technical Field

[0001] The present invention relates to the technical field of mold processing, and in particular to a metal surface pretreatment system for the processing of thermal barrier coating metal molds. Background Art

[0002] A thermal barrier coating is a coating material used on the surface of high-temperature components. Sprayed on the surface of a metal mold, it plays roles such as heat insulation, protecting the substrate, and improving the performance of the component.

[0003] Before spraying a thermal barrier coating on the surface of a metal mold, in order to enhance the adhesion of the coating and improve the uniformity of the coating, it is usually necessary to clean its surface. Laser cleaning is a widely used cleaning technology at present. This cleaning method uses a laser beam with a high energy density to remove dirt, rust, coatings and other impurities on the surface of an object. This non-contact cleaning method has advantages such as good cleaning effect, high cleaning accuracy, and environmental protection and no pollution.

[0004] When laser cleaning a metal mold plate, it is necessary to first place the metal mold plate on the operating table manually or by an external robotic arm and position it, and then clean it with a laser cleaning device. When the laser cleaning process of a metal mold is completed, it is necessary to remove the cleaned metal mold from the fixed tooling fixture, place it at a designated position beside, and then re-clamp a new metal mold plate to be cleaned on the tooling to prepare for the next round of laser cleaning operation. In large-scale and continuous industrial production scenarios, a large amount of time is consumed during the process of frequently placing and positioning molds, removing the cleaned molds, loading new molds and re-positioning, which is not convenient and will lengthen the cleaning cycle of a single metal mold plate, resulting in a limited number of metal molds that can be cleaned and enter the thermal barrier coating spraying process per unit time. Summary of the Invention

[0005] In view of the above-mentioned drawbacks of the prior art, the present invention provides a metal surface pretreatment system for the processing of thermal barrier coating metal molds, which can effectively solve the problem in the prior art that in large-scale and continuous industrial production scenarios, a large amount of time is consumed during the process of frequently placing and positioning molds, removing the cleaned molds, loading new molds and re-positioning, which is not convenient and will lengthen the cleaning cycle of a single metal mold plate, resulting in a limited number of metal molds that can be cleaned and enter the thermal barrier coating spraying process per unit time.

[0006] To achieve the above object, the present invention is realized through the following technical solutions:

During this period, the limiting mechanism will press and clamp the mold to prevent it from falling. During the second week of rotation of the flipping mechanism, the rotating frame will flip back to its original position, realizing automatic material discharge after laser cleaning.

[0012] Further, the placing mechanism includes a placing table. The placing table is fixedly connected between the two rotating frames. A plurality of mounting holes are uniformly opened on the upper end surface of the placing table. A plurality of limiting rods are detachably mounted in a matrix arrangement in the plurality of mounting holes, and the distribution positions of the plurality of limiting rods coincide with the outer shape of the mold. The limiting rods adopt a two-section design. The upper end is designed to be inclined to facilitate the placement of the mold, and the lower end is designed to be vertical to limit the position of the mold. A knocking component is connected below the placing table.

[0013] Further, the knocking component includes an arc-shaped plate. The arc-shaped plate is fixedly connected to the lower end surface of the placing table. A plurality of annular parts are uniformly fixedly connected to the arc-shaped section of the arc-shaped plate.

A notch corresponding to the arc-shaped plate is penetrated and opened on the placing table.

[0014] Further, the limiting mechanism includes a limiting frame. There are two limiting frames symmetrically arranged on the left and right. Both limiting frames are rotatably connected between the two rotating frames through rotating rods. A plurality of limiting plates that press the mold to prevent it from falling during the flipping process are uniformly fixedly connected to the front and back of the limiting frame.

[0015] Further, spring pressing seats that press the edge position of the mold are slidably connected along the length direction of two of the front and back symmetrically arranged limiting plates on the same limiting frame, and spring pressing seats that are used to adapt to molds of different thicknesses are also fixedly connected to the remaining limiting plates on the same limiting frame.

[0016] Furthermore, the flip mechanism includes an installation chamber, the rear end of the installation chamber is provided with an opening and is arranged on the front side of the support through a base, an annular toggle frame is rotatably connected in the installation chamber and close to the rear end, a mounting plate is rotatably connected on the installation chamber at the rear of the annular toggle frame, an arc-shaped rack is fixedly connected to the circumferential inner surface of the annular toggle frame, the front end of the left rotating rod passes through the installation plate and the fixed sleeve is provided with a transmission gear 1 meshing with the teeth on the arc-shaped rack, the front end of the right rotating rod passes through the installation plate and the fixed sleeve is provided with a transmission gear 2, a transmission gear 3 meshing with the transmission gear 2 is rotatably connected to the installation plate through a gear mounting rod, the gear mounting rod and the left rotating rod are connected by belt drive, and a pushing assembly is installed on the circumferential inner surface of the annular toggle frame.

[0017] Furthermore, the pushing assembly includes a connecting frame, the circumferential inner surface of the annular toggle frame is fixedly connected to the connecting frame at the lower left side of the mounting plate, a push rod is slidably connected to the connecting frame front and back, a positioning rod is fixedly connected to the front end of the push rod, an annular seat is fixedly connected to the circumferential inner surface of the mounting chamber, a guide groove is provided on the circumferential inner surface of the annular seat and the positioning rod is slidably connected in the guide groove, and the guide groove adopts a multi-stage design so that the positioning rod will move forward when it is rotated to the right side, so that the rear end of the push rod is misaligned with the mounting plate.

[0018] Furthermore, the locking mechanism includes a locking rod, which is symmetrically and slidably connected to the rear support, a positioning slider is fixedly connected to the side wall of the locking rod and the rear position, and a groove wheel is rotatably connected to the rear end of the rear support. A wheel groove is provided on the circumferential inner surface of the groove wheel, and the positioning slider is slidably connected in the wheel groove. When the groove wheel rotates, the positioning slider will slide in the wheel groove, thereby driving the locking rod to move forward to the bottom of the rotating frame and the limit frame or to be pulled out from under the two backwards, thereby realizing the locking and unlocking of the rotating frame and the limit frame.

[0019] Furthermore, the driving mechanism includes a bottom shaft, which is rotatably installed under the support, one end of the bottom shaft is fixedly connected to a servo motor, and a connecting shaft is fixedly connected to the annular toggle frame.

[0021] The present invention realizes automation through the coordinated operation of a driving mechanism, a flipping mechanism, etc. After the laser cleaning is completed, the servo motor is started to drive the bottom shaft to rotate, and the annular toggle frame is rotated twice in a belt transmission manner. In the first week, the rotating frame and the mold are driven to flip to the bottom and automatically unload the material; in the second week, the rotating frame is flipped and reset. There is no need for frequent manual loading and unloading of the mold throughout the whole process, which greatly shortens the cleaning cycle, increases the number of molds that can be cleaned and enter the spraying process per unit time, and improves production efficiency. The mold may fall during the flipping process, affecting the quality of the mold and subsequent processing. To solve this problem, the system is provided with a limiting mechanism. In the first stage of flipping, the servo motor drives the bottom shaft to rotate, and through gear transmission, the limit frames on both sides rotate synchronously in opposite directions, and the mold is firmly pressed on the placement table by the spring pressing seat. When falling, the sliding spring seat limits the corners of the mold to prevent it from tilting and falling, and the limit frame opens gradually to avoid the mold from falling too fast and being damaged by collision, thereby ensuring the integrity of the mold and facilitating subsequent processing.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention will be further described below in conjunction with the embodiments.

[0036] Example:

[0037] See also Figures 1 - 10 The present invention provides a technical solution: a metal surface pretreatment system for thermal barrier coating metal mold processing, comprising:

[0038] The placing part 1, the placing part 1 includes a support 11, on which two rotating frames 12 are symmetrically and rotatably connected in the front and back, and a placing mechanism 13 for placing a mold and centering it is jointly installed on the two rotating frames 12.

[0039] The flipping part 2, the flipping part 2 includes a flipping mechanism 21, the flipping mechanism 21 is installed on the support 11 and is connected to the front rotating frame 12 to drive it to flip 180 degrees. A locking mechanism 22 for locking the rear rotating frame 12 when it stays in the horizontal state is connected to the rear side of the support 11. A driving mechanism 23 is jointly connected to the locking mechanism 22 and the flipping mechanism 21.

[0040] Among them, a limiting mechanism 24 for preventing the mold from falling during the flipping process is also installed on the two rotating frames 12.

[0041] Among them, after the mold is placed on the placing mechanism 13, it will be automatically centered and positioned. The upper surface of the mold is cleaned by a laser cleaning machine. After the cleaning is completed, the driving mechanism 23 operates to drive the flipping mechanism 21 to rotate two weeks. In the first week of rotation of the flipping mechanism 21, it will drive the rotating frame 12 and the mold to flip downward and automatically discharge the material. During this period, the limiting mechanism 24 will press and clamp the mold to prevent it from falling. In the second week of rotation of the flipping mechanism 21, the rotating frame 12 will flip back to its original position, so as to realize automatic material discharge after laser cleaning.

[0042] The placing mechanism 13 includes a placing table 131, the placing table 131 is fixedly connected between the two rotating frames 12. A plurality of mounting holes 1311 are evenly opened on the upper end surface of the placing table 131. A plurality of limiting rods 132 are detachably installed in a matrix arrangement in several mounting holes 1311, and the distribution positions of the plurality of limiting rods 132 match the shape of the mold. The limiting rods 132 adopt a two-section design. The upper end adopts an inclined design to facilitate the placement of the mold, and the lower end adopts a vertical design to limit the position of the mold. A knocking assembly 133 is connected below the placing table 131.

[0043] Among them, the action end of the laser cleaning equipment is arranged above the placing table 131, which is an existing equipment and is not shown in the figure.

[0044] During specific work, the mold plate to be cleaned is aligned and placed on the placing table 131 manually or by a robotic arm. Since the mold is made of metal and has a large weight, it will slide down along the inclined section of the limiting rod 132 under its own weight and fall on the placing table 131, so as to realize automatic positioning.

[0045] It is worth mentioning that the purpose of installing the limit rod 132 on the placement table 131 in a detachable manner is to increase its versatility. Specifically, the limit rod 132 is removed and reinserted into the mounting holes 1311 at different positions. The distribution position of the limit rod 132 can be freely adjusted within a certain range according to the outer contour of the mold.

[0046] After the mold is positioned by the limiting rod 132, the laser cleaning device can set its cleaning path accordingly, so as to avoid the occurrence of partial repeated cleaning or missed cleaning of some areas due to positioning deviation as much as possible.

[0047] The knocking assembly 133 includes an arc-shaped plate 1331, which is fixedly connected to the lower end surface of the placement table 131. A plurality of annular parts 1332 are evenly and fixedly connected to the arc segment of the arc-shaped plate 1331. A plurality of knocking rods 1333 that can be used for knocking the mold are slidably connected to the annular parts 1332. A notch corresponding to the arc-shaped plate 1331 is opened through the placement table 131.

[0048] The limiting mechanism 24 includes a limiting frame 241, and two limiting frames 241 are symmetrically arranged on the left and right. The two limiting frames 241 are rotatably connected between the two rotating frames 12 through a rotating rod. The limiting frames 241 are evenly fixedly connected with a plurality of limiting plates in the front and back to press the mold to prevent it from falling during the flipping process. Two of the limiting plates symmetrical in the front and back on the same limiting frame 241 are slidably connected with a spring pressing seat 242 for pressing the edge position of the mold along the length direction thereof, and the remaining limiting plates on the same limiting frame 241 are also fixedly connected with spring pressing seats 242 for adapting to molds of different thicknesses.

[0049] The flip mechanism 21 includes an installation chamber 211, the rear end of which is provided with an opening and is arranged on the front side of the support 11 through a base, an annular toggle frame 212 is rotatably connected in the installation chamber 211 and close to the rear end, a mounting plate 213 is rotatably connected on the installation chamber 211 at the rear of the annular toggle frame 212, an arcuate rack 214 is fixedly connected to the circumferential inner surface of the annular toggle frame 212, the front end of the left rotating rod passes through the installation plate 213 and is fixedly sleeved with a transmission gear 1 215 meshing with the teeth on the arcuate rack 214, the front end of the right rotating rod passes through the installation plate 213 and is fixedly sleeved with a transmission gear 216, a transmission gear 3 217 meshing with the transmission gear 216 is rotatably connected to the installation plate 213 through a gear installation rod, the gear installation rod and the left rotating rod are connected by belt drive, and a pushing assembly 218 is installed on the circumferential inner surface of the annular toggle frame 212.

[0050] The pushing assembly 218 includes a connecting frame 2181, the circumferential inner surface of the annular toggle frame 212 is fixedly connected with the connecting frame 2181 at the lower left of the mounting plate 213, a push rod 2182 is slidably connected to the connecting frame 2181, a positioning rod 2183 is fixedly connected to the front end of the push rod 2182, an annular seat 2184 is fixedly connected to the circumferential inner surface of the mounting chamber 211, a guide groove 2185 is provided on the circumferential inner surface of the annular seat 2184, and the positioning rod 2183 is slidably connected in the guide groove 2185, and the guide groove 2185 adopts a multi-stage design to enable the positioning rod 2183 to move forward when it is rotated to the right side, so that the rear end of the push rod 2182 is misaligned with the mounting plate 213.

[0051] The locking mechanism 22 includes a locking rod 221, which is symmetrically and slidably connected to the rear support 11. A positioning slider 222 is fixedly connected to the side wall and the rear position of the locking rod 221. A groove wheel 223 is rotatably connected to the rear end of the rear support 11. A wheel groove 224 is opened on the inner surface of the circumference of the groove wheel 223. The positioning slider 222 is slidably connected in the wheel groove 224. When the groove wheel 223 rotates, the positioning slider 222 will slide in the wheel groove 224, thereby driving the locking rod 221 to move forward to the bottom of the rotating frame 12 and the limiting frame 241 or to be pulled out from the bottom of the two backwards, thereby realizing the locking and unlocking of the rotating frame 12 and the limiting frame 241.

[0052] The driving mechanism 23 includes a bottom shaft 231, which is rotatably installed under the support 11, one end of the bottom shaft 231 is fixedly connected to a servo motor, and a connecting shaft 232 is fixedly connected to the annular toggle frame 212. The front end of the connecting shaft 232 rotates through the installation chamber 211 and is connected to the bottom shaft 231 through a belt drive, and the transmission ratio between the two is the same. The bottom shaft 231 and the two groove wheels 223 are all connected through a belt drive, and the transmission ratio between the three is the same.

[0053] During specific work, after laser cleaning is completed, the mold needs to be removed from the placement table 131. At this time, the servo motor is started to drive the bottom shaft 231 to rotate, thereby driving the connecting shaft 232 to rotate synchronously through the belt transmission, and the rotation of the connecting shaft 232 drives the annular toggle frame 212 to rotate synchronously.

[0054] It is worth mentioning that the annular shifting frame 212 needs to rotate two times during the entire material cutting process. For ease of understanding, the process is described in four stages with half a turn as one stage (half a turn here is not exactly 180 degrees, the first and third stages are slightly greater than 180 degrees, and the second and fourth stages are slightly less than 180 degrees).

[0055] In the first stage, the annular shifting frame 212 rotates from the initial state to 180 degrees. In the initial state, the placing table 131 and the mold are both facing upward (such asFigure 10 As shown in a), the rotating frame 12 and the mounting plate 213 are both in a horizontal state. At this time, the head of the arc-shaped rack 214 is meshed with the transmission gear 215 to lock it. In this state, the upper ends of the two limit plates are opened to avoid obstruction to the laser cleaning process. At this time, the positioning slider 222 is located at the frontmost end point in the wheel groove 224, so the two locking rods 221 are also in a relatively forward position, supporting the bottom of the placement table 131 from both sides of the action, so as to maintain it in a horizontal state.

[0056] When the servo motor drives the bottom shaft 231, the connecting shaft 232 and the connecting shaft 2322 to rotate in a belt transmission manner, the arc-shaped rack 214 drives the transmission gear 1 215 to rotate clockwise, and the rotation of the transmission gear 1 215 drives the left rotating rod to rotate synchronously clockwise, so that the left limiting frame 241 rotates synchronously clockwise to press the mold. The rotation of the transmission gear 1 215 also drives the transmission gear 3 217 to rotate synchronously in a belt transmission manner, thereby driving the transmission gear 2 216 to rotate synchronously counterclockwise. Then, while the left limiting frame 241 rotates clockwise, the right limiting frame 241 also rotates synchronously counterclockwise under the drive of the transmission gear 2 216, and the mold is pressed and fixed on the placement table 131 through the spring pressing seat 242 thereon (such as Figure 2 ).

[0057] When the rotating shaft 1 rotates and drives the annular toggle frame 212 to rotate, the bottom shaft 231 also drives the two groove wheels 223 to rotate synchronously through belt transmission. The rotation of the groove wheel 223 will cause the positioning slider 222 to slide backward in the wheel groove 224, so that the locking rod 221 moves backward synchronously, releasing the limit on the bottom of the placement table 131. When the arc-shaped rack 214 moves to the tail and engages with the transmission gear 1 215, the rotation action of the above-mentioned limit frame 241 and the unlocking action of the locking rod 221 are just completed. At this time, the connecting frame 2181 and the push rod 2182 also happen to move to abut against the mounting plate 213, and then as the annular toggle frame 212 continues to rotate, the mounting plate 213 and the rotating frame 12 will be driven to rotate synchronously through the push rod 2182.

[0058] When the push rod 2182 pushes the mounting plate 213 to rotate clockwise, the tail of the arc-shaped rack 214 and the transmission gear 215 are always engaged, thereby locking the rotating rod to prevent it from swinging under the action of the mold and its own gravity. At the same time, when the push rod 2182 is rotating, the adjustment rod 2183 also slides along the guide groove 2185. When the mounting plate 213 is about to flip 180 degrees, the adjustment rod 2183 moves to the front arc section of the guide groove 2185, thereby driving the push rod 2182 to be pulled out of the dislocation from the bottom of the mounting plate 213. At this time, the locking rod 221 is extended again under the action of the positioning slider 222 and the groove wheel 223, first positioning the rotating frame 12 on the rear side, and then extending to the bottom of the two limit frames 241 to support the two respectively.

[0059] In this state, since the arc plate 1331 is at the top, the knocking rod 1333 thereon falls under its own gravity. Due to the shape characteristics of the arc plate 1331, the distances between each knocking rod 1333 and the mold are different, so there will be a time difference in the knocking, thereby simulating the process of manually knocking on the mold multiple times to promote the falling of residual contaminants in the mold cavity.

[0060] The second stage, that is, when the mounting plate 213 and the mounting frame are in a horizontal state under the action of the locking rod 221 (such as Figure 10 As shown in FIG. 2 b , as the annular toggle frame 212 continues to rotate clockwise, the transmission gear 215 moves to the lower right. As the annular toggle frame 212 continues to rotate, the arc-shaped rack 214 is driven to continue to rotate until its tail is disengaged from the transmission gear 215. This process may cause the rotating rod connected to the transmission gear 215 to further rotate clockwise. However, since the limit frame 241 presses and limits the mold through the spring seat, the rotation will not cause any negative impact.

[0061] At the beginning of the second stage of rotation of the annular toggle frame 212, the push rod 2182 is still in a misaligned state with the mounting plate 213, so it does not contact the mounting plate 213. The mounting plate 213, the rotating frame 12, the mold and the two limit frames 241 are all in a horizontal state under the action of the locking rod 221. When the annular toggle frame 212 rotates to the left again (such as Figure 10 The locking rod 221 will release the lock of the limit frame 241 in the same principle as the initial unlocking. The rotation of the transmission gear 216 will drive the rotating rod connected to it to rotate clockwise synchronously. When the transmission gear 216 is rotated and pressed for the first time, the transmission gear 216 rotates clockwise. Therefore, when it rotates clockwise, it will drive the limit frame 241 to release the pressing limit on the mold, and at the same time drive the transmission gear to rotate synchronously and drive the rotating rod connected to it to rotate to release the pressing limit on the mold (as shown in FIG. Figure 10 (shown in d).

[0062] It should be noted that during this process, the process of the two limit frames 241 rotating synchronously in opposite directions is a gradual process to prevent the mold from falling too fast and causing bumps. At the same time, the spring seats slidably mounted on the limit plates will provide a certain limit support for the corners on the left and right sides of the mold to prevent it from being unstable on the left and right sides and tilting and falling through the gap between the two limit plates at the final stage of falling. When the two limit plates rotate synchronously in opposite directions to a slightly larger angle than the initial angle, the push rod 2182 also moves below the mounting plate 213 and contacts it.

[0063] The movement processes in the subsequent third stage and fourth stage are respectively similar to those in the first stage and second stage. In the third stage, the annular toggle frame 212 rotates and drives the placement table 131 to rotate and reset to the initial position again through the push rod 2182 in the same way as in the first stage. In the fourth stage, the rotation of the annular toggle frame 212 drives the push rod 2182 and the arc-shaped rack 214 to move and reset to the initial position in the same way as in the second stage.

[0064] The above process is repeated continuously, and the automatic centering positioning, automatic blanking, and automatic knocking and dust removal of the mold can be realized.

[0065] It should be noted that the metal surface pretreatment system for the above-mentioned thermal barrier coating metal mold processing has the following advantages:

[0066] Advantage 1: High efficiency and automation, improving production efficiency. In the prior art, manual loading and unloading of molds takes a long time and the cleaning cycle is long. This system realizes automation through the coordinated operation of the driving mechanism 23, the flipping mechanism 21, etc. After the laser cleaning is completed, the servo motor drives the bottom shaft 231 to rotate, and through the belt drive, the annular toggle frame 212 rotates two weeks. In the first week, it drives the rotating frame 12 and the mold to flip and blank. In the second week, it resets. The whole process does not require frequent manual loading and unloading, shortens the cleaning cycle, and increases the number of molds that can be cleaned and enter the spraying process per unit time.

[0067] Advantage 2: Multiple protections to ensure the safety of the mold. To prevent the mold from falling during the flipping process, the system is provided with a limiting mechanism 24. In the first stage of flipping, the motor drives the bottom shaft 231 to rotate. Through the gear drive, the two limit frames 241 rotate synchronously in opposite directions, and the mold is firmly pressed on the placement table 131 through the spring pressing seat 242. When falling, the sliding spring seat limits the corners of the mold to prevent it from tilting and falling. The limit frames 241 are gradually opened to avoid the mold falling too fast and being damaged by collision, ensuring the integrity of the mold and facilitating subsequent processing.

[0068] Advantage 3. Simulating manual operation to optimize the cleaning effect: There may be problems of impurity residue in traditional cleaning. The placement mechanism 13 of this system is provided with a knocking component 133. When the mold is flipped 180 degrees, the knocking rod 1333 on the arc plate 1331 falls due to gravity. Due to the different distances from the mold, a time difference is generated, simulating multiple manual knocks, promoting the falling of the residual pollutants in the mold cavity, improving the cleaning effect, and enhancing the adhesion and uniformity of the thermal barrier coating.

[0069] Advantage 4. Flexible adjustment to enhance the versatility of the equipment: The existing cleaning equipment has poor adaptability to different molds. In the placement mechanism 13 of this system, the limit rod 132 is detachably installed, and its distribution position can be adjusted according to the outer contour of the mold, realizing the automatic positioning of different molds, improving the adaptability of the equipment to a variety of molds, and meeting the diverse production requirements.
