Description

Technical Field

[0001] This invention relates to the field of control panel processing technology, and in particular to a fully automatic injection molding equipment for control panels and its control method. Background Technology

[0002] The control panel, as one of the components of a machine, such as Figure 8 As shown, it includes an ink layer 410, a metal decorative layer 420, and a base plate layer 430. It is generally used for the control of electrical components in machinery and for receiving and processing data. It mainly consists of a display device, NC keyboard, MCP, status lights, handheld unit, etc. Injection molding is one of the processing methods, and injection molding equipment is the main equipment for injection molding.

[0003] However, it still has the following drawbacks in practical use:

[0004] Existing control panel injection molding equipment typically involves material loading during the molding process, followed by a transition to another process, air blowing, and then a final material unloading process. This manual operation is time-consuming, labor-intensive, and inefficient.

[0005] Meanwhile, during the injection molding process, the injection body is generally injected directly through the injection channel to control the injection molding of the front panel. However, it is impossible to bypass the metal decorative layer at its edge, making it difficult to reduce the impact on the printed material and affecting actual use.

[0006] Therefore, it cannot meet the needs of actual use, so there is an urgent need for improved technologies on the market to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a fully automatic injection molding equipment for control panels and its control method. By setting up a multi-functional material handling mechanism and a molding injection mold, this invention solves the problems of existing control panel injection molding equipment. In the molding process, the equipment typically involves first placing the material, then switching to another process of blowing air, and then switching to a material handling process after blowing air. This manual operation is time-consuming, labor-intensive, and inefficient. Furthermore, it cannot avoid the metal layer at the edge of the injection molded product, making it difficult to reduce the impact on the printing material and affecting its actual use.

[0008] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0009] A fully automatic injection molding machine for control panels.

[0010] Including the injection molding machine body;

[0011] A molding die connected to the inside of the injection molding machine body for injection molding of the control panel;

[0012] The molding injection mold includes an upper mold plate and a lower mold plate, as well as injection runners provided in the upper mold plate and the lower mold plate and venting channels opened at the corners of the upper mold plate and the lower mold plate;

[0013] The injection runner includes a main injection runner vertically opened in the upper mold plate and a branch injection runner opened on the lower mold plate. The branch injection runner includes at least one bypass runner. The bypass runner extends downward from outside the cavity of the product to be injection molded, bypasses the side edge of the cavity, and extends to the middle of the cavity to mold the product to be injection molded.

[0014] And a multi-functional material handling mechanism connected to the middle of one side of the upper end of the injection molding machine body to perform multiple operations;

[0015] The multi-functional material handling mechanism is connected to the three-axis robotic arm of the injection molding machine to perform mold forming material handling functions. The multi-functional material handling mechanism includes:

[0016] The feeding assembly includes a vertical feeding rack and a top feeding assembly. The vertical feeding rack has several feeding slots on one side, and the top feeding assembly pushes the material in the feeding slots into the mold.

[0017] A material-grabbing component is rotatably disposed below a material-discharging component. The material-grabbing component includes an adsorption element for adsorbing and removing the injection-molded product.

[0018] The three-axis robot arm used in the injection molding machine is used to guide the position movement of the material handling mechanism.

[0019] As a further improvement, the top-loading assembly includes a driving component and a supporting component. The supporting component is a connecting plate, and the connecting plate is fixedly connected to both sides of the driving cylinder. The connecting plate is fixedly connected to the vertical material placement rack. The driving component is a driving cylinder, and the three-axis robot is fixedly connected to the driving cylinder.

[0020] As a further improvement, the top material assembly includes a top material component, which includes an ejector plate, a top rod, and a top material plate. The output end of the drive cylinder is fixedly connected to the ejector plate, and several top rods are fixedly installed on one side of the ejector plate. The top rods movably pass through the discharge chute and are fixedly connected to the top material plate.

[0021] As a further improvement, the multi-functional material handling mechanism further includes an air blowing assembly, which includes a hollow support, a connecting pipe connected to the middle of the bottom of the hollow support and extending into the interior, and multiple air blowing pipes that are equidistantly connected to the center of the front end of the hollow support.

[0022] As a further improvement, the material handling assembly includes a fixing member, which is a U-shaped frame, and the U-shaped frame is fixedly installed on the bottom surface of the drive cylinder.

[0023] As a further improvement, the material handling assembly includes a rotating component, which includes a rotating motor and a flipping plate. The flipping plate is rotatably connected between the inner walls of the U-shaped frame. The rotating motor is fixedly installed on one side of the outer wall of the U-shaped frame. The output shaft of the rotating motor is fixedly connected to the flipping plate. The adsorption component includes rubber suction heads. The flipping plate is provided with several rubber suction heads.

[0024] As a further improvement, the flip plate is provided with a movable clamp.

[0025] As a further improvement, the glue injection channel further includes a first channel formed on the surface of the lower template to divide the main glue injection channel into two, and a second channel formed on the surface of the lower template to divide the two first channels into two respectively. The number of bypass channels is four, and they are respectively set at the end of the second channel.

[0026] As a further improvement, the bypass channel is horn-shaped, and the diameter of the bypass channel gradually decreases from thick to thin in the glue infeed direction.

[0027] A control method for a fully automatic injection molding equipment with a control panel includes the following specific implementation methods:

[0028] S1: The three-axis robot arm adjusts the multi-functional material handling mechanism to the worktable in front of the operator. At this time, the material handling component and the material handling component are in a vertical position.

[0029] S2: The surface coating is placed manually in the feeding trough. The three-axis robot is adjusted so that it drives the multi-functional material handling mechanism to move to the front of the air blowing component. The air blowing component blows air to remove dust from the surface coating.

[0030] S3: Move the surface appearance layer to the top of the injection molding machine, then open the lower mold plate of the injection molding machine, adjust the rotation of the material taking component to make it parallel to the material feeding component, then adjust the three-axis robot to align the material feeding component with the upper mold plate, and push the surface appearance layer material in the feeding groove into the upper mold plate by adjusting the ejector component.

[0031] S4: Adjust the three-axis robot to move the material handling component to the side of the lower mold plate. After the lower mold plate ejects the injection molded product, the robot will suck out the injection molded product from the lower mold plate through the suction component. After the material head is clamped off by the movable clamp, the material handling component moves out of the injection molding machine with four finished products. Adjust the rotation of the material unloading component to achieve a perpendicular state with the material handling component.

[0032] S5: Adjust the three-axis robot arm to move the multi-functional material handling mechanism in front of the operator. At this time, the material handling component is flush with the worktable. Adjust the suction component so that it no longer suctions the injection molded product, so that the injection molded product falls freely onto the worktable for people to pick up in time. At the same time, the lower mold plate closes the mold.

[0033] S6: Injection molding is performed. The injection plastic flows through the main injection channel of the upper mold plate and then through the injection branch channel of the lower mold plate. The injection plastic is then divided into two or four branches by the first branch channel and the second branch channel. Finally, it flows downward through an arc and then through the bypass channel to the bottom of the injection molded product for injection molding. This avoids the metal material on the edge of the workpiece that is easily washed away and reduces the impact on the printing material of the main body of the workpiece.

[0034] S7: Open the mold and repeat steps S1 to S6.

[0035] The present invention has the following beneficial effects:

[0036] This invention features a multi-functional material handling mechanism, which includes an air blowing component, a material handling component, and a material discharging component. It integrates the material handling, discharging, and air blowing structures for processing molded objects into a single unit, and uses a mechanical structure to replace manual operation. This reduces the time loss caused by switching between multiple workstations, reduces the intensity of manual labor, improves work efficiency, is easy to use, and meets the requirements.

[0037] At the same time, a molding injection mold is added. After receiving the external injection material through the first and second runners, a bypass runner is used for receiving. This allows the injection material to go down through a circular arc and then back to be placed under the product. This is used to bypass the metal material on the edge of the workpiece that is easily washed away, and to reduce the impact on the printing material of the workpiece body. It is easy to use and meets the requirements.

[0038] Furthermore, the exhaust channel can discharge the gas generated during injection molding, thereby improving the quality and aesthetics of the injection-molded product.

[0039] Meanwhile, the bypass channel included in the injection module adopts a split and modular form, which can be easily disassembled and assembled, facilitating quick structural replacement for different subsequent needs.

[0040] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0053] Please refer to Figures 1 to 7 A fully automatic injection molding machine for control panels.

[0054] Includes the injection molding machine body 100;

[0055] A molding injection mold 200 connected to the inside of the injection molding machine body 100 for injection molding of the control panel;

[0056] The molding injection mold 200 includes an upper mold plate 210 and a lower mold plate 221, as well as injection flow channels provided in the upper mold plate 210 and the lower mold plate 221 and venting channels 223 opened at the corners of the upper mold plate 210 and the lower mold plate 221;

[0057] The injection runner includes a main injection runner vertically formed in the upper mold plate 210 and a branch injection runner 2221 formed on the lower mold plate 221. The branch injection runner 2221 includes at least one bypass runner 2201. The bypass runner 2201 extends downward from outside the cavity of the product to be injection molded 400, bypasses the side edge of the cavity, and extends to the middle of the cavity to form the product to be injection molded 400.

[0058] And, a multi-functional material handling mechanism 300 connected to the middle of one side of the upper end of the injection molding machine body 100 to perform multiple operations;

[0059] The multi-functional material handling mechanism 300 is connected to the three-axis robot arm 500 for the injection molding machine, and performs the mold forming material handling function. The multi-functional material handling mechanism 300 includes:

[0060] The feeding assembly 320 includes a vertical feeding rack 325 and a top feeding assembly. The vertical feeding rack 325 has a plurality of feeding slots 5 on one side, and the top feeding assembly pushes the material in the feeding slots 5 into the mold.

[0061] The material picking component 330 is rotatably disposed below the material dispensing component 320. The material picking component 330 includes an adsorption element for adsorbing and removing the injection-molded product.

[0062] The three-axis robot 500 used in the injection molding machine is used to guide the position movement of the material handling mechanism.

[0063] This invention utilizes a multi-functional material handling mechanism 300 in conjunction with a molding injection mold 200. The multi-functional material handling mechanism 300 automatically handles material handling, material feeding, and air blowing. Simultaneously, the mold employs a horn-shaped bypass flow channel 2201 for receiving the material, allowing the injection molding material to flow downwards through an arc before returning to its position below the product. This avoids the easily eroded edge metal decorative strips on the workpiece and reduces the impact on the printing material of the workpiece body. The structure is ingeniously designed and easy to use. By replacing manual operation with an integrated mechanical structure, it reduces the time loss caused by switching between multiple workstations, reduces the intensity of manual labor, and improves operational efficiency. It is easy to use and meets the requirements.

[0064] like Figures 2-5 and Figure 8 As shown, the multi-functional material handling mechanism 300 of the present invention has the following specific structure: a three-axis robot 500 for injection molding machine is used to guide the material handling mechanism in position movement. The three-axis robot 500 is equipped with an air blowing component 340. The multi-functional material handling mechanism 300 is connected to the three-axis robot 500 for injection molding machine to perform mold forming material handling function. The multi-functional material handling mechanism 300 includes a material handling component 320 and a material handling component 330. The material handling component 320 includes a vertical material rack 325 and a material ejector component. A plurality of material handling slots 5 are opened on one side of the vertical material rack 325. The material ejector component pushes the material in the material handling slots 5 into the mold. The material handling component 330 is rotatably located below the material handling component 320. The material handling component 330 includes an adsorption component to adsorb and remove the injection-molded product.

[0065] In use, the three-axis robot arm 500 adjusts the multi-functional material handling mechanism 300 to the worktable in front of the operator. At this time, the material handling component 320 and the material handling component 330 are in a vertical position. The material handling component 330 is not working at this time, which can reduce the space occupied by the material handling component 330 and facilitate manual material handling.

[0066] Then, the surface layer is placed in the feeding trough 5 manually, and the three-axis robot arm 500 is adjusted so that it drives the multi-functional material handling mechanism 300 to move to the air blowing component 340. The air blowing component 340 blows air to remove dust from the surface layer.

[0067] Then the surface appearance layer is moved to the top of the injection molding machine. Then the lower mold plate 221 of the injection molding machine is opened. The material taking component 330 is adjusted to rotate so that it is parallel to the material feeding component 320. At this time, the three-axis robot arm 500 is adjusted so that the material feeding component 320 is aligned with the upper mold plate 210. And by adjusting the ejector component, the surface appearance layer material in the feeding groove 5 is pushed into the upper mold plate 210.

[0068] At this point, adjust the three-axis robot 500 so that it can move the material handling component 330 to one side of the lower mold plate 221. After the lower mold plate 221 pushes out the injection molded product 400, it can suck out the injection molded product on the lower mold plate 221 through the suction component. Then adjust the material dispensing component 320 and the material handling component 330 to be in a vertical state.

[0069] Then, the three-axis robot arm 500 is adjusted to move the multi-functional material handling mechanism 300 in front of the operator. At this time, the material handling component 330 is flush with the worktable. The suction component is adjusted so that it no longer holds the injection molded product 400, so the injection molded product 400 falls freely onto the worktable for easy removal. At the same time, the upper left mold plate 210 closes and continues the injection molding process, thus realizing automatic material feeding and picking, solving the problems of manual material feeding and picking, which are time-consuming, labor-intensive, and inefficient.

[0070] Furthermore, such as Figure 2 and Figure 3 As shown, the top material assembly further includes a driving component, which is a driving cylinder 327. The three-axis robot arm 500 is fixedly connected to the driving cylinder 327. The top material assembly includes a support component, which is a connecting plate 6. The connecting plate 6 is fixedly connected to both sides of the driving cylinder 327. The connecting plate 6 is fixedly connected to the vertical material rack 325. The top material assembly includes a top material component, which includes an ejector plate 324, a push rod 329, and a top material plate 328. The output end of the driving cylinder 327 is fixedly connected to the ejector plate 324. Several push rods 329 are fixedly installed on one side of the ejector plate 324. The push rods 329 movably pass through the material discharge chute 5 and are fixedly connected to the top material plate 328.

[0071] The specific working principle of the top material assembly is as follows: When it is necessary to push the surface appearance layer in the material discharge slot 5 out of the material discharge slot 5 and into the upper template 210, the drive cylinder 327 is adjusted to drive the ejector plate 324 to move closer to the vertical material rack 325. The ejector plate 324 drives the push rod 329 to move. The push rod 329 drives the top material plate 328 to move towards the slot opening of the material discharge slot 5, thereby pushing the surface appearance layer in the material discharge slot 5 out of the material discharge slot 5 and into the upper template 210.

[0072] Furthermore, such as Figure 2 and Figure 5 As shown, the material handling component 330 includes a fixing component, which is a U-shaped frame 331. The U-shaped frame 331 is fixedly installed on the bottom surface of the drive cylinder 327. The material handling component 330 includes a rotating component, which includes a rotating motor 332 and a flipping plate 333. The flipping plate 333 is rotatably connected between the inner walls of the U-shaped frame 331. The rotating motor 332 is fixedly installed on one side of the outer wall of the U-shaped frame 331. The output shaft of the rotating motor 332 is fixedly connected to the flipping plate 333. The suction component includes rubber suction heads 334. The flipping plate 333 is provided with several rubber suction heads 334 and a movable clamp 335.

[0073] The specific working principle of the material handling component 330 is as follows: When the rubber suction head 334 is adjusted to rotate and adsorb the injection molded product 400, the forward-starting rotating motor 332 drives the flip plate 333 to rotate, so that the flip plate 333 is parallel to the vertical material rack 325. The flip plate 333 drives the rubber suction head 334 to rotate, so that it aligns with the lower template 221 and adsorbs and removes the injection molded product 400 pushed out of the lower template 221. The lower template 221 is the injection molded bottom plate layer 430.

[0074] The injection molded product 400 is then adsorbed by the rubber suction head 334, and the material head is clamped off by the movable clamp 335 to obtain a complete injection molded product 400. This is the existing technology.

[0075] After the material head is clamped off, the rotating motor 332 is started in reverse, which drives the flipping plate 333 to rotate, making the flipping plate 333 parallel to the vertical material rack 325, and finally making the rubber suction head 334 face downward. This makes it convenient for the rubber suction head 334 to no longer adhere to the injection molded product 400 when the three-axis robot arm 500 adjusts the material picking component 330 to move it to the worktable. The injection molded product 400 can automatically fall onto the worktable.

[0076] In addition, please refer to Figure 4 The multifunctional material handling mechanism 300 further includes an air blowing assembly 340. The air blowing assembly 340 includes a hollow support, a connecting pipe connected to the middle of the bottom of the hollow support and extending into the interior, and multiple air blowing pipes that are equidistantly connected to the center of the front end of the hollow support. The connecting pipe is connected to the multiple air blowing pipes to achieve simultaneous gas delivery and rapid dust removal from the workpiece surface.

[0077] Please refer to Figure 1 , Figures 6 to 8 The specific structure of its injection mold 200 includes the following:

[0078] Upper mold plate 210 and lower mold plate 221, and injection flow channels provided in upper mold plate 210 and lower mold plate 221;

[0079] The injection runner includes a main injection channel vertically opened in the upper mold plate 210 and an injection branch channel 2221 opened on the lower mold plate 221. The injection branch channel 2221 includes at least one bypass channel 2201. The bypass channel 2201 extends downward from outside the cavity of the product to be injection molded 400, bypasses the side edge of the cavity, and extends to the middle of the cavity to form the product to be injection molded 400.

[0080] The injection molding flow channel of the present invention adopts a bull horn-shaped bypass flow channel 2201 for receiving treatment, so that the injection molding material passes downward through a section of arc and then returns to be set under the product. This is used to bypass the edge decorative strip that is easily washed away from the edge of the workpiece and to reduce the impact on the printing material of the workpiece body. The structure is ingeniously designed and easy to use.

[0081] Please refer to Figure 6 and Figure 7 The bypass flow channel 2201 is horn-shaped, and the diameter of the bypass flow channel 2201 gradually decreases from thick to thin in the direction of glue injection. This design can effectively ensure sufficient glue volume through the thick diameter flow channel, while ensuring sufficient injection pressure during final injection molding through the thin diameter.

[0082] Please refer to Figure 6 The glue injection channel 2221 further includes a first channel 201 formed on the surface of the lower template 221 to divide the main glue injection channel into two, and a second channel 202 formed on the surface of the lower template 221 to divide the two first channels 201 into two. The number of bypass channels 2201 is four, and they are respectively set at the end of the second channel 202. In this way, one can simultaneously output four, and complete the simultaneous forming of multiple workpieces.

[0083] Among them, such as Figure 6 As shown, any injection venting channel 223 includes a receiving channel, a longitudinal venting channel located at the middle of the outer end of the receiving channel and extending to the outside, a transverse venting channel located at the middle of one side of the receiving channel and extending to the outside, and multiple guide channels equidistantly located inside the receiving channel. During the injection molding process of the above-mentioned product, since the product is very thin, if there is air in the cavity, it is easy to leave bubbles on the product. Therefore, the air in the cavity can be transported to the receiving channel through the guide channel, and then transported to the transverse venting channel and the longitudinal venting channel through the receiving channel to achieve the exhaust of gas.

[0084] A protrusion is connected to the middle of one end of the space formed on the inner side of any receiving channel. The protrusion is used to limit and fix the printed panel after the edge decorative strip and the surface decorative layer are combined, so as to prevent the position from shifting during the injection molding process.

[0085] Please refer to Figure 6 and Figure 7 The lower template 221 is provided with eight combination blocks, and each pair of combination blocks is spliced ​​together for use. Each combination block has a horn-shaped groove so that the two combination blocks can be spliced ​​together to form a bypass flow channel 2201.

[0086] The bypass channel 2201 adopts a detachable modular structure, which can be disassembled and assembled at will. It is easy to quickly replace the structure when using it for different needs or after long-term wear and tear. The structure is ingeniously designed and easy to use.

[0087] Please refer to Figures 1 to 8 A control method for a fully automatic injection molding equipment with a control panel, comprising the following specific implementation methods:

[0088] S1: Adjust the multi-functional material handling mechanism 300 to the worktable in front of the operator using the three-axis robot 500. At this time, the material handling component 320 and the material handling component 330 are in a vertical state.

[0089] S2: The surface appearance layer is placed manually in the feeding trough 5. The three-axis robot arm 500 is adjusted so that it drives the multi-functional material handling mechanism 300 to move to the front of the air blowing component 340. The air blowing component 340 blows air to remove dust from the surface appearance layer.

[0090] S3: Move the surface appearance layer to the top of the injection molding machine, then open the lower mold plate 221 of the injection molding machine, adjust the rotation of the material taking component 330 to make it parallel to the material feeding component 320, and then adjust the three-axis robot 500 to align the material feeding component 320 with the upper mold plate 210, and push the surface appearance layer material in the feeding groove 5 into the upper mold plate 210 by adjusting the ejector component;

[0091] S4: Adjust the three-axis robot arm 500 so that it drives the material handling component 330 to move to one side of the lower mold plate 221. After the lower mold plate 221 pushes out the injection molded product 400, it will suck out the injection-molded product on the lower mold plate 221 through the suction component. After the material head is clamped off by the movable clamp 335, the material handling component 330 moves out of the injection molding machine with four finished products. Adjust the rotation of the material discharging component 320 to achieve a perpendicular state with the material handling component 330.

[0092] S5: Adjust the three-axis robot arm 500 to move the multi-functional material handling mechanism 300 to the front of the operator. At this time, the material handling component 330 is flush with the worktable. Adjust the suction component so that it no longer suctions the injection molded product 400, so that the injection molded product 400 falls freely onto the worktable for people to pick up in time. At the same time, the lower mold plate 221 closes the mold.

[0093] S6: Injection molding is performed. The injection plastic flows through the main injection channel of the upper mold 210 and then through the injection branch channel 2221 of the lower mold 221. The injection plastic is then divided into two or four streams by the first branch channel 201 and the second branch channel 202. Finally, it flows downward through a section of arc and then through the bypass channel to reach the injection product 400 for injection molding. This avoids the metal material on the edge of the workpiece that is easily washed away and reduces the impact on the printing material of the main body of the workpiece.

[0094] S7: Open the mold and repeat steps S1 to S6.
