Description

Technical Field

[0001] This invention relates to the field of automated inductor production technology, and in particular to an automated hot pressing system and method for inductors. Background Technology

[0002] As a fundamental electronic component, surface mount power inductors are characterized by miniaturization, high quality, high energy storage, and low resistance. They are widely used in various electronic devices or electronic control circuits. Currently, various electronic devices are developing towards miniaturization, lightweighting, and multifunctionality, and the number of surface mount inductors used is increasing. However, this also puts forward new requirements for surface mount inductors, such as miniaturization, low mounting thickness, and large inductance. At the same time, the market's requirements for product quality and production capacity are also increasing.

[0003] In existing technologies, the hot pressing equipment for power inductors has a low degree of automation. It usually requires manual handling of molds and manual operation of equipment, resulting in low overall efficiency and high labor costs, which is not conducive to mass production. A few manufacturers use automated equipment to manufacture power inductors, using a conveyor mechanism to connect multiple sets of equipment to achieve automated production. However, there are still some problems: the conveyor mechanism often uses conveyor belts, slide rails and other conveying components to carry the forming mold. When starting, stopping or turning, it is easy to cause vibration or collision of the fixture, which can cause the inductor blank inside the forming mold to tilt or shift. Ultimately, this results in poor quality of the finished inductor and a low pass rate. Summary of the Invention

[0048] Step S1, Implantation process: The controller controls the transport mechanism to transfer the molding mold to the area of ​​the implantation machine and place it on the transfer mechanism associated with the implantation machine. Then, the controller controls the transfer mechanism to transport the molding mold into the implantation machine, thereby controlling the implantation machine to implant the inductor blank to be hot-pressed into the molding mold.

Then, the controller controls the transfer mechanism to transport the molded mold into the powder filling machine, thereby controlling the powder filling machine to fill the molded mold with powder. After the powder filling process is completed, the controller controls the transfer mechanism to return to the initial position along with the molded mold.

[0050] Step S3, hot pressing process: The controller controls the transport mechanism to transport the molding die after the powder filling process to the area of ​​the hot press and place it on the transfer mechanism associated with the hot press. Then, the controller controls the transfer mechanism to transport the molding die into the hot press, thereby controlling the hot press to hot press the inductor blank and powder in the molding die. After the hot pressing process is completed, the controller controls the transfer mechanism to return to the initial position along with the molding die.

[0051] Step S4, Demolding process: The controller controls the transport mechanism to transport the molding die after the hot pressing process to the area of ​​the demolding machine and place it on the transfer mechanism associated with the demolding machine. Then, the controller controls the transfer mechanism to transport the molding die into the demolding machine, thereby controlling the demolding machine to demold the inductor blank in the molding die, and finally obtain the molded inductor blank. After the demolding process is completed, the controller controls the transfer mechanism to return to the initial position together with the molding die.

At the same time, it rationally arranges the number of each hot pressing equipment according to the time required for each process, shortens the waiting time between processes, and ensures the continuity of the process.

[0055] 3. The use of a gripping mechanism to grip and place the forming mold improves production stability and ensures product performance and quality; at the same time, the forming mold can be recycled and reused, reducing the demand for molds and reducing equipment costs.

[0056] 4. The hot pressing equipment is placed around the transport mechanism, resulting in a small overall size and saving space. Attached Figure Description

[0066] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within the scope of the present invention.

[0067] In a preferred embodiment of the present invention, based on the above-mentioned problems existing in the prior art, an automatic hot-pressing system for inductors is provided, such as... Figure 1 As shown, it includes:

[0068] Multiple hot press equipment 100, each hot press equipment 100 includes an implantation machine 1, a powder filling machine 2, at least one hot press 3 and a demolding machine 4;

[0069] The conveying system 200 includes a transport mechanism 5 and a transfer mechanism 300 respectively associated with each hot pressing device 100;

[0070] The controller 6 is connected to the conveying system 200 and the hot pressing equipment 100 respectively. It is used to control the carrying mechanism 5 to transfer the molding mold between the areas of each hot pressing equipment 100, and to control the corresponding transfer mechanism 300 to transport the transferred molding mold to the associated hot pressing equipment 100. It also controls each hot pressing equipment 100 to perform the implantation, powder filling, hot pressing and demolding processes respectively to prepare the inductor blank.

[0071] Specifically, in this embodiment, the conveying system 200 is used to connect multiple independent hot pressing devices 100 and integrate them into a complete automatic hot pressing system. The carrying mechanism 5 is set between each hot pressing device 100 and is mainly responsible for transporting the molding die to the area where each hot pressing device 100 is located. There are multiple transfer mechanisms 300, and each independent hot pressing device 100 corresponds to a transfer mechanism 300. The transfer mechanism 300 is mainly responsible for directly transferring the molding die transported by the carrying mechanism 5 to the working area of ​​each hot pressing device 100 so that each hot pressing device 100 can directly carry out the preparation process.

[0072] In an automatic hot pressing system, the multiple hot pressing devices 100 and the conveying system 200 can be optionally positioned in one of the following ways: Figure 1 As shown, the automatic hot pressing system is equipped with one implantation machine 1, one powder filling machine 2, two hot presses 3, and one demolding machine 4, according to the preparation time required for each process. Each hot pressing device 100 is located at one of the four corners of the transport mechanism 5. The overall size of the equipment is small, saving space. The powder filling machine 2 and demolding machine 4, with their small footprint, can be placed on the same platform. Since the hot pressing process requires a long time, two or more hot presses can be selected to ensure the continuity of the entire hot pressing process.

[0073] It should be noted that, for the sake of simplicity and clarity, some of the internal cylinders, sliders, and steel frames supporting the various components are not shown in the figure.

[0079] Specifically, in this embodiment, as follows: Figure 2 As shown, the main slide rail 7 is set horizontally, spanning the area between each hot press device 100. The conveying platform 8 is slidably connected to the main slide rail 7 via the main slider 9. The conveying platform 8 can grasp the forming mold through the rotation of the robotic arm 11 and the robotic arm gripper 12, and transport the forming mold back and forth to the area where each hot press device 100 is located. It should be noted that the transport mechanism 5 also includes a drive positioning component laid along the main slide rail 7 to ensure the accuracy of grasping and placement, such as a ball screw laid along the main slide rail 7 and a nut assembly sleeved on the ball screw. Precise positioning can be achieved in many ways, which will not be elaborated here.

[0080] More specifically, multiple conveying zones 10 can be set according to actual needs. In this embodiment, there are two conveying zones 10. When entering a certain process, one conveying zone 10 is used to place the molding mold that has completed the previous process. The molding mold that has completed the previous process is taken out and placed in the other conveying zone 10, and the molding mold to be processed is put in for the preparation of the next batch.

[0081] In a preferred embodiment of the present invention, the transfer mechanism 300 includes a first transfer mechanism 310 associated with the implantation device 1, the first transfer mechanism 310 being disposed between the transport mechanism 5 and the implantation device 1, such as...

[0114] The second lifting cylinder 3411 is located on one side of the second lifting platform 3410, and the second lifting cylinder 3411 is connected to the second lifting platform 3410 and the controller 6.

[0115] Specifically, in this embodiment, the fourth transfer mechanism 340 is disposed between the transport mechanism 5 and the demolding machine 4, such as... Figure 7 As shown, the fifth drive mechanism 342 can be positioned in the transfer direction parallel to the transport mechanism 5 via the fifth slide rail 341. The fifth drive mechanism 342 is provided with a second gripping mechanism 345. Below the second gripping mechanism 345, a second slide cylinder 348 and a third slide cylinder 349 are arranged side by side. The second slide cylinder 348 is provided with a cooling zone 346, and the third slide cylinder 349 is provided with a demolding zone 347. The horizontal height of the demolding zone 347 is consistent with the horizontal height of the demolding platform of the demolding machine 4. When the third slide cylinder 349 pushes the demolding zone 347 toward the demolding machine 4, the demolding zone 347 can fit against the demolding platform.

[0116] More specifically, the second slide cylinder 348 is equipped with push plates at both ends of the cooling zone 346. The lower end of the push plate overlaps with the side of the middle template of the forming mold but does not exceed the lower end of the middle template. When the second slide cylinder 348 drives the push plate to move forward, it can separate the middle template in the cooling zone 346 from the middle template base. This accelerates the cooling speed and facilitates the subsequent demolding process. The separated middle template is transported by the second gripping mechanism 345 to the demolding zone 347 on the third slide cylinder 349. The end of the third slide cylinder 349 near the demolding machine 4 is also equipped with a liftable second pull table 3410. The lower end of the second pull table 3410 is equipped with a second pull buckle. The second pull table 3410 can drive the second pull buckle downward to snap into the positioning hole of the middle template. The third slide cylinder 349 drives the second pull table 3410 to extend and push the middle template into the demolding platform of the demolding machine 4 for the subsequent demolding process.

[0117] In addition, the first drive mechanism 312, the second drive structure 316, the third drive mechanism 322, the fourth drive mechanism 332 and the fifth drive mechanism 342 all include the same drive positioning components as the above-mentioned transport mechanism 5, which respectively cooperate with the first displacement motor 314, the second displacement motor 319, the third displacement motor 325, the fourth displacement motor 334 and the fifth displacement motor 344 to control the movement and positioning of the molding die.

[0118] In a preferred embodiment of the present invention, the automatic hot pressing system further includes position sensors. Position sensors are provided in the storage area 14, the conveying area 10, the implantation area 318, the powder filling area 324, the buffer area 336, the pressing area 337, the preheating area 338, the cooling area 346, and the demolding area 347. The position sensors are connected to the controller 6 and send position change signals to the controller 6.

[0119] In a preferred embodiment of the present invention, such as Figure 2 As shown, the transport mechanism 5 has multiple storage areas 14 on one side for placing molding dies.

[0120] Specifically, in this embodiment, the storage area 14 can be set up in multiple ways according to actual needs, that is, multiple empty molding molds can be set up. When the first process is completed and the second process is started, the transport mechanism 5 can pick up a new molding mold to continue the first process. This cycle continues until the last process is completed, after which the molding mold returns to the empty state and is put back into the new round of processes. This can ensure that each process is carried out at the same time, improve the preparation efficiency, and at the same time, the molding mold can be recycled and reused, reducing the demand for molds and reducing equipment costs.

[0121] It should be noted that the molding die has a positioning hole that runs through the top and bottom, such as... Figure 2 As shown, the conveying area 10 and the storage area 14 are equipped with positioning pins 15 that match the positioning holes to ensure that the molding die remains stable during the conveying process.

[0122] In a preferred embodiment of the present invention, a camera detection device is provided above the area where the implantation machine 1 and the demolding machine 4 are located, and is connected to the controller 6.

[0123] Specifically, in this embodiment, the camera detection device of the implantation machine 1 is mainly used to detect whether there are defects such as reverse material, upright material, or stacked material in the implanted molding die; the camera detection device of the demolding machine 4 is mainly used to detect whether the molded inductor blank in the molding die has been completely demolded.

[0124] In a preferred embodiment of the present invention, such as Figure 5 As shown, the third transfer mechanism 330 also includes a preheating mechanism 3315, which is located below the preheating zone 338.

[0125] This invention also provides an automatic hot-pressing method for inductors, applied to the aforementioned automatic hot-pressing system, such as... Figure 8 As shown, the automatic hot pressing method includes:

[0126] Step S1, Implantation process: The controller controls the transport mechanism to transfer the molding mold to the area of ​​the implantation machine and place it on the transfer mechanism associated with the implantation machine. Then, the controller controls the transfer mechanism to transport the molding mold into the implantation machine, thereby controlling the implantation machine to implant the inductor blank to be hot-pressed into the molding mold. After the implantation process is completed, the controller controls the transfer mechanism to return to the initial position along with the molding mold.

[0127] Step S2, powder filling process: The controller controls the transport mechanism to transfer the molded mold after the implantation process to the area of ​​the powder filling machine and place it on the transfer mechanism associated with the powder filling machine. Then, the controller controls the transfer mechanism to transport the molded mold into the powder filling machine, thereby controlling the powder filling machine to fill the molded mold with powder. After the powder filling process is completed, the controller controls the transfer mechanism to return to the initial position along with the molded mold.

[0128] Step S3, hot pressing process: The controller controls the transport mechanism to transport the molding die after the powder filling process to the area of ​​the hot press and place it on the transfer mechanism associated with the hot press. Then, the controller controls the transfer mechanism to transport the molding die into the hot press, thereby controlling the hot press to hot press the inductor blank and powder in the molding die. After the hot pressing process is completed, the controller controls the transfer mechanism to return to the initial position along with the molding die.

[0129] Step S4, Demolding process: The controller controls the transport mechanism to transport the molding die after the hot pressing process to the area of ​​the demolding machine and place it on the transfer mechanism associated with the demolding machine. Then, the controller controls the transfer mechanism to transport the molding die into the demolding machine, thereby controlling the demolding machine to demold the inductor blank in the molding die, and finally obtain the molded inductor blank. After the demolding process is completed, the controller controls the transfer mechanism to return to the initial position along with the molding die.

[0130] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present invention.
