[0002] Resin crafts generally refer to objects made primarily of resin, cast using molds, and hand-carved. Considering the landscaping requirements of these crafts, various fixed-shape mimicry structures are often incorporated, such as mountains and trees. These structures can be pre-molded and cured with resin or carved from wood.

[0003] The processing of the aforementioned combined handicrafts often requires multiple batches of resin injection molding of the semi-finished products to obtain the complete handicraft. Existing methods of multiple batch resin processing rely on manual labor, involving steps beyond simply weighing raw materials, mixing, blending, and targeted injection / coating. The overall process is numerous and complex, resulting in lengthy production times and low efficiency. Therefore, this application proposes a new technical solution. Summary of the Invention

Detailed Implementation

[0041] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0042] This application discloses a processing platform for the preparation of resin and wood combined handicrafts.

[0043] Reference Figure 1 and Figure 2 The processing platform used in the preparation of resin and wood combined handicrafts includes an injection molding workbench 1, a camera module 2, a material storage mechanism 3, and a mixing mechanism 4. In this embodiment, the injection molding workbench 1 refers to a workbench with an injection head that can move in three dimensions. For example, it includes at least a base 11, a platform 12 mounted on the base 11, a three-axis robotic arm 13, and an injection head mounted on the three-axis robotic arm 13. In use, the semi-finished product of the handicraft (such as the wooden structure part) is placed on the platform 12, and the three-axis robotic arm 13 moves on the x, y, and z axes to control the injection head to perform injection work at different positions.

[0044] Understandably, the aforementioned semi-finished products should be supported by a chassis and surrounded by barriers to prevent resin from flowing erratically. Furthermore, the aforementioned injection head does not refer to a single nozzle structure, but rather a composite functional component similar to the dispensing head of a dispensing machine, capable of at least pumping and extruding materials.

[0045] The camera module 2 includes an industrial CCD camera, which can be mounted on the moving part of the injection worktable 1 (e.g., the front side wall of the injection head) with the lens facing downwards, to photograph the semi-finished products placed on the table 12, and to assist in the movement and positioning of the injection head.

[0046] Reference Figure 3 and Figure 4The storage mechanism 3 includes a storage tank 31 for storing liquid resin and a conveying assembly 32 connected to the storage tank 31. The mixing mechanism 4 includes a mixing tank 41, a pigment box 42 installed on the side wall of the mixing tank 41, and a shaking stirring mechanism 43 for driving the mixing tank 41 to shake. The pigment box 42 is connected to the inner cavity of the mixing tank 41 via a pipe, which can be a flexible hose, and the pipe and pigment box 42 are detachably connected. A flow control valve 411 is installed on the pipe connecting to the pigment box 42. In this embodiment, the flow control valve 411 refers to an electrically controlled valve integrating a flow meter to detect the flow rate and control the discharge of material from the pipe.

[0047] When in use, after the resin is fed into the mixing tank 41, the flow control valve 411 is opened to add the required pigment, and then the shaking and stirring mechanism 43 is controlled to make the raw materials in the mixing tank 41 uniformly mixed.

[0048] The discharge end of the material conveying component 32 is connected to the mixing tank 41, and is used to convey raw materials into the mixing tank 41. The camera module 2, the material conveying component 32, the shaking and stirring mechanism 43, and the flow control valve 411 are respectively electrically connected to the controller of the injection molding worktable 1 (the three-axis robotic arm 13). The controller of the injection molding worktable 1 is configured as follows:

[0049] 1) Obtain and record the resin color formula, 3D model or coloring effect diagram of the target craft, and injection molding steps uploaded by the user.

[0050] For example, if the red resin to be prepared requires red pigment at a ratio of 1:500, then record and upload the formula.

[0051] The 3D model and the colored rendering can be created in advance by the staff using modeling software and then uploaded.

[0052] The injection molding process refers to the process instructions given by the staff: based on only a wooden semi-finished product, first mold which type of resin in which part, then mold which type of resin in which part, etc.

[0053] 2) Based on the image data acquired by camera module 2, identify and determine the current injection molding step and the next injection molding step;

[0054] The above describes the process of performing feature recognition on the image to identify existing features, comparing them with the 3D model to determine which features are still missing, and determining which features should be formed in the next step based on the injection molding process.

[0055] To avoid misjudgment caused by highly transparent resin features, this application prefers to process handicrafts without highly transparent structures, or to issue a prompt when processing highly transparent structures, reminding humans to keep an eye on and intervene, and requiring manual review and confirmation of the correctness of the steps before performing the injection molding operation.

[0056] 3) If you are ready to proceed to the next injection molding step, obtain the feed amount of the material feeding assembly 32.

[0057] 4) Based on the resin color corresponding to the next injection molding step, the pre-recorded resin color formula and the feeding amount, obtain the pigment to be dripped and the corresponding amount to be dripped.

[0058] 5) Control the flow control valve 411 to operate based on the amount of pigment to be added and the amount to be added.

[0059] According to the above settings, workers can place the wooden structure of the craft on the injection molding workbench 1, input the 3D model and rendering of the finished product, and then the injection molding workbench 1 can automatically identify the structure on the table 12 using the camera module 2, and dispense the resin part of the craft according to the given injection molding steps to complete the craft processing; because there is no longer a need for manual dispensing of resin, it is relatively convenient to use, and the machine automatically replenishes the resin part, which improves production efficiency and is suitable for industrial mass production.

[0060] In one embodiment of this application, the platform is used in a factory batch operation scenario. The storage bin 31 is relatively large in volume, so it is not installed on the injection molding workbench 1, but is fixed with legs at the bottom so that the legs are placed on the ground.

[0061] Reference Figure 3 and Figure 4 The material conveying assembly 32 includes a pushing unit 321, a piston block 322 connected to the telescopic end of the pushing unit 321, and a material conveying pipe 323 with one end connected to the outlet of the storage tank 31. The other end of the material conveying pipe 323 is connected to the mixing tank 41. Most of the material conveying pipe 323 is made of flexible hose, and the part in the bending section is made of rigid pipe, which helps to prevent the material conveying resin and other materials from being obstructed due to the bending of the flexible hose.

[0062] The piston block 322 is vertically slidably connected to the inner cavity of the storage tank 31. A bracket for mounting the pushing unit 321 is provided above the storage tank 31. The pushing unit 321 can be an electric cylinder with its telescopic end facing downward. When the electric cylinder pushes the piston block 322 downward, it can push the resin in the storage tank 31 into the conveying pipe 323.

[0063] The reason why the above-mentioned structure is used to transport resin raw materials is that the solidification and coagulation of resin after a long period of time will damage the pump and other components. The above-mentioned setup satisfies the feeding requirements on the one hand, and the electric cylinder push length control allows for more precise control of the feeding amount on the other hand.

[0064] The push unit 321 is electrically connected to the controller of the injection molding worktable 1, thereby controlling the push unit 321 to perform material feeding operations. Example of use:

[0065] The feeding amount of the material conveying component 32 is calculated as follows:

[0066] If a signal is received from the driving unit 321 to start working, the working time t1 of the driving unit 321 is recorded; for example, the time is 2 seconds.

[0067] Obtain the speed v of the extension end of the pushing unit 321;

[0068] Based on the working time t1 and the speed v of the extension end of the push unit 321, the extension length L is calculated; assuming the extension speed of the push unit 321 is 50mm / s and the pushing time is 2s, the extension length is 100mm.

[0069] Obtain the cross-sectional area S of the inner cavity of the storage bin 31; wherein the cross-sectional area is determined according to the specifications of the storage bin 31.

[0070] The feeding amount of the conveying assembly 32 is calculated based on the extension length L1 of the telescopic end and the cross-sectional area S of the inner cavity of the storage bucket 31; where the feeding amount of the conveying assembly 32 = S·L1. Assume S is 20cm. 2 Based on the aforementioned distance, the feeding capacity of the material conveying component 32 is 200cm. 3 .

[0071] With the above settings, the feeding amount can be counted without setting up a separate flow meter. Only some initial specifications or values ​​need to be entered, and the controller of the injection molding workbench 1 can automatically calculate the feeding amount of the feeding component 32, which is convenient and efficient to use.

[0072] In another embodiment of this application, the material conveying assembly 32 further includes a pipe opening and closing assembly 324 for controlling the opening and closing of the outlet of the material conveying pipe 323.

[0073] Because resin tends to stick to the inlet or outlet, potentially causing blockage in the feed pipe 323, the following settings are implemented:

[0074] Reference Figure 5 The discharge end of the conveying pipe 323 is located above and downward of the mixing barrel 41; the pipe opening and closing assembly 324 includes a sealing plate 3242 and a cylinder 3241. The sealing plate 3242 is fixed to the telescopic end of the cylinder 3241 and covers the discharge end of the conveying pipe 323. The cylinder 3241 extends and retracts laterally, and both the cylinder 3241 and the conveying pipe 323 are supported by a physical structure. The details will be explained later.

[0075] According to the above configuration, while cylinder 3241 extends and retracts to drive the sealing plate 3242 to seal the feed pipe 323, the plate can also scrape away some of the residual resin that has solidified at the opening of the feed pipe 323, reducing the possibility of blockage in the feed pipe 323. The cylinder 3241 is electrically connected to the controller of the injection molding worktable 1.

[0076] Reference Figure 2 and Figure 6 In one embodiment of this application, the pigment box 42 includes multiple chambers, each with an air hole at its top. Each chamber is connected to a pipe and has a corresponding flow control valve 411. The pigment box 42 is fixed to the outer wall of the mixing tank 41, and the outlet end of the pipe penetrates the side wall of the mixing tank 41 to add pigment. Example: The pigment box 42 may include at least four chambers for holding four types of pigments: red, yellow, blue, and white, facilitating color control through formulation.

[0077] A cover 421 is slidably connected to the top of the paint box 42. The cover 421 has multiple through holes, the number of which is equal to the number of chambers. After the end of the cover 421 abuts against the end of the paint box 42, the through holes and the air holes are opposite each other. After the cover 421 is pulled out, the through holes and the air holes are staggered vertically, that is, the through holes are located exactly at the top of the paint box 42 where there are no holes, and gas cannot flow into the paint box 42 through the through holes and the air holes.

[0078] A cylinder 422 is installed on the side wall of the mixing tank 41. The telescopic end of the cylinder 422 is connected to the cover 421. The cylinder 422 is used to push the cover 421 to insert and withdraw. The cylinder 422 is electrically connected to the controller of the injection molding worktable 1. Example of use: The controller of the injection molding worktable 1 is configured such that if it receives a signal feedback that the flow control valve 411 has started to work, it controls the cylinder 422 to extend its telescopic end.

[0079] With the above settings, because the pigment box 42 is divided into multiple chambers, multiple pigments can be added and mixed according to the color configuration formula to obtain the final desired color. When shaking the mixing tank 41, the closed cap 421 and flow control valve 411 can also prevent the pigment from being shaken out. In addition, the through hole on the cap 421 can use the principle of air pressure balance to control the flow of pigment without affecting the addition of pigment.

[0080] In one embodiment of this application, a gantry frame 5 is provided, and a base 6 is provided below the crossbeam of the gantry frame 5. The mixing barrel 41 is placed on the base 6, and the side wall is hinged to the base 6 through a pivot. The bottom is funnel-shaped so that the mixing barrel 41 can maintain a vertical posture in its natural state.

[0081] Reference Figure 4The crossbeam of the gantry frame 5 is slidably connected to the mounting base 7, which moves on the crossbeam by an electric trolley or a screw slide; the shaking stirring mechanism 43 is set on the mounting base 7; the aforementioned cylinder 3241 and conveying pipe 323 can be fixed below the mounting base 7 by a hanging rod.

[0082] The shaking and stirring mechanism 43 includes a bucket lid 431, a vertical electric cylinder 432, a traction rope 433, a fixed pulley 434, and a tension generator 435.

[0083] The cylinder body of the vertical electric cylinder 432 is hinged to the mounting base 7 and located to the side of the conveying pipe 323; the telescopic rod end of the vertical electric cylinder 432 points downward and is hinged to the top center of the barrel cover 431. The fixed pulley 434 is located to the side of the vertical electric cylinder 432 and is rotatably connected to the mounting base 7. The traction rope 433 passes around the fixed pulley 434 and is fixed at one end to the side wall of the cylinder body of the vertical electric cylinder 432, and the other end is connected downward to the tension generator 435.

[0084] When mixing is required, the vertical electric cylinder 432 extends to close the lid 431 to the mixing barrel 41. Then, the tension generator 435 pulls the traction rope 433, and the vertical electric cylinder 432 extends and retracts accordingly, keeping the mixing barrel 41 closed while driving the mixing barrel 41 to swing, so as to mix the materials in the barrel.

[0085] A distance measuring sensor 8 is fixed in the barrel lid 431. The distance measuring sensor 8 can be a laser distance measuring sensor 8 with the probe facing a preset protrusion on the inner side wall of the barrel. The distance measuring sensor 8, the vertical electric cylinder 432 and other electrical devices are respectively connected to the controller of the injection molding worktable 1.

[0086] As can be seen from the above, the controller can determine the position of the lid 431 relative to the mixing barrel 41 based on the feedback from the ranging sensor 8, so as to coordinate the control of the vertical electric cylinder 432 and keep the lid 431 covering the mixing barrel 41.

[0087] Reference Figure 7 In one embodiment of this application, the tension generator 435 includes a magnetic block 4351 and an electromagnet 4352. The magnetic block 4351 is fixed to the end of the traction rope 433 away from the vertical electric cylinder 432, and the electromagnet 4352 is located below the magnetic block 4351.

[0088] According to the above settings, when the electromagnet 4352 is activated and the magnetic block 4351 is activated, the traction rope 433 can be pulled to pull the vertical electric cylinder 432. When the electromagnet 4352 is deactivated and the magnetic block 4351 is released, the traction rope 433 can be released, allowing the vertical electric cylinder 432 to swing back.

[0089] To prevent the magnetic block 4351 from shaking and affecting its performance, a guide tube 4353 is provided, in which the magnetic block 4351 and the electromagnet 4352 are vertically distributed.

[0090] The reason for adopting the above-mentioned tension generation design in this embodiment is that the electric cylinder and other electric propulsion structures have rigid connection nodes, which require repeated extension and retraction. Moreover, the resin is relatively viscous and needs to be shaken quickly for stirring. To shake quickly, the electric propulsion structure needs to perform repeated actions very quickly, which will make the equipment more prone to damage. In addition, the swing of the mixing tank 41 will be completely restricted at this time, and it is impossible to swing by inertia. Therefore, this application specifically sets the aforementioned magnetic attraction structure. When the magnetic release is performed, the mixing tank 41 can be kept swinging at a high speed by swinging while simultaneously by having a simulated person pull the traction rope 433 quickly from time to time.

[0091] Furthermore, a lifting cylinder 4354 is also provided. The cylinder body of the lifting cylinder 4354 is supported and fixed by a base plate, etc., and the telescopic rod faces upward. An electromagnet 4352 is installed at the end of the telescopic rod of the lifting cylinder 4354. The lifting cylinder 4354 is electrically connected to the controller of the injection molding worktable 1.

[0092] Based on the above configuration, this application can raise and lower the electromagnet 4352 to get closer to the magnetic block 4351 when necessary, so as to attract the magnetic block 4351 with less magnetic force or energy consumption.

[0093] In order to determine the relative position of the magnetic block 4351 as a guide for controlling the lifting cylinder 4354, a distance sensor 4355 can be fixed on the top of the guide tube 4353. The detection end of the distance sensor 4355 faces downward and its detection path intersects with the movement path of the magnetic block 4351. The electrical signal of the distance sensor 4355 is connected to the controller of the injection molding worktable 1.

[0094] In another embodiment of this application, the controller of the injection molding worktable 1 is configured as follows:

[0095] The pushing action parameters of the pushing unit 321 are obtained, and the amount of material in the mixing tank 41 is obtained based on the pushing action parameters; that is, the extension and retraction of the electric cylinder and the movement of the piston block 322 are obtained. Then, the total amount of material extruded can be calculated by using the volume formula combined with the known inner diameter of the storage tank 31, which is equivalent to the amount of material in the mixing tank 41. The calculation process has been given an example above and will not be repeated here.

[0096] The attraction force, descent height, and activation frequency of the electromagnet 4352 are controlled based on the amount of material.

[0097] Example: The more material there is, the heavier the mixing bucket 41 will be. Similarly, when the electromagnet 4352 is close to the magnetic block 4351, the stronger the attraction will be, so as to ensure that the mixing bucket 41 can be pulled to swing well and that the energy consumption is not too wasteful.

[0098] At the same time, the smaller the descent height, the less likely the material will easily sway to the outlet position, and the more it will lay the foundation for increasing the oscillation frequency.

[0099] The activation frequency of electromagnet 4352 is increased. For example, initially, electromagnet 4352 is activated once every 6 swing cycles to accelerate the pull when magnetic block 4351 descends. Now that the material quantity is 1 / 2 of the capacity of the mixing bucket 41, it changes to activating electromagnet 4352 once every 3 swing cycles.

[0100] The specific mathematical relationship, i.e., the ratio, between the above material quantities and other parameters can be customized by the staff based on experience; according to the above settings, mixing can be carried out relatively energy-efficiently and is relatively unaffected by the material quantity.

[0101] In one embodiment of this application, considering that the resin used in the crafts may have different colors, it would be troublesome to manually clean the mixing tank 41 after each different color is mixed. Therefore, the following settings are also made:

[0102] Reference Figure 8 A color film isolation sleeve 9 is provided inside the mixing tank 41. The color film isolation sleeve 9 is attached to the inner wall of the mixing tank 41, and is hollow inside with an opening at the top. The bottom of the color film isolation sleeve 9 is preferably made of rubber, while other parts are made of metal or plastic. A vertical inner pull rod 91 is fixed to the inner bottom of the color film isolation sleeve 9. A magnetic block 2 is fixed to the top of the inner pull rod 91. The bottom of the inner pull rod 91 has a rigid base plate to maintain its verticality as much as possible.

[0103] The side wall of the bucket lid 431 is used to abut against the inner wall of the color film isolation sleeve 9. At least one electromagnet is hung at the bottom of the bucket lid 431 by a rope, and at least one electromagnet is located directly above the magnetic block 2.

[0104] The injection molding workbench 1 is connected to the bottom of the mixing tank 41 by multiple pipes, each of which is connected to the discharge section of an injection head.

[0105] Based on the above settings, the controller can be configured to allow the lid 431 to continue moving downwards before different colored resins are mixed, so that the electromagnet 2 is close to the magnetic block 2 and attracted. This allows the color film isolation sleeve 9 to be removed from the mixing tank 41 and placed aside. Then, a new color film isolation sleeve 9 can be picked up and placed into the mixing tank 41. In other words, when multiple colors of resin are needed for each processing, it is no longer necessary to manually clean the mixing tank 41 in the middle, and it can also ensure that the resin colors do not mix.

[0106] Furthermore, because the bottom of the color film isolation sleeve 9 is flexible, it can be placed directly on the ground;

[0107] Furthermore, if a certain color of resin is not used up, it can be taken out and put back when necessary. This way, when processing multi-colored handicrafts in batches, it is no longer necessary to go through the process of mixing different colors for each handicraft. One batch of materials can be used for multiple productions, which is more efficient.

[0108] Furthermore, since the aforementioned electromagnet 2 is not exposed and can be placed in the resin, it will also be used as a stirrer to accelerate the mixing process. In addition to electromagnet 2, the inner wall of the color film isolation sleeve 9 can also be spring-connected to other floats of different weights to accelerate the mixing process in multiple layers. It should be noted that the spring is covered with a rubber sleeve to avoid direct contact with the resin.

[0109] It is understandable that the positions of the aforementioned pigment box 42 and material conveying pipe 323 are also based on the above settings, so as to facilitate their coordination and prevent interference when the color film isolation sleeve 9 moves; it should be noted that the side wall of the color film isolation sleeve 9 has holes corresponding to the pipe outlet of the pigment box 42, and the bottom has holes corresponding to the pipe of the injection molding worktable 1.

[0110] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
