Description

Technical Field

[0001] This invention belongs to the field of button technology, and particularly relates to a molding panel manufacturing process, a molding panel, and a controller. Background Technology

[0002] Buttons are common instruction or data input devices in electronic control systems. They are activated by the user applying force or torque, converting the instruction or data into an electrical signal. This signal is then processed by the corresponding circuitry and transmitted to the main control chip. Existing button structures include an electronic switch and an actuating element. Under normal circumstances, the electronic switch is electrically disconnected. When the user applies force or torque to the actuating element, the actuating element transmits the force or torque to the electronic switch, activating its electrical connection and triggering an electrical signal. This signal is then transmitted to the main control chip. With the continuous development and widespread application of large-scale integrated circuit technology… Numerous electronic components are integrated onto a single printed circuit board (PCB). The electronic switches in the function keys are also integrated onto the PCB. The actuating elements have gradually evolved into button posts integrated onto a silicone panel. The button posts are used to withstand the operating force or torque applied by the user. Because silicone is soft and easily deformed, it often cannot be correctly assembled with other components such as the PCB due to deformation, resulting in large assembly errors and affecting the normal use of some function keys. In addition, because silicone is soft, it is easily damaged during assembly, causing the silicone panel to be scrapped and resulting in waste of raw materials.

[0003] In the prior art, patent document with publication number "CN215988535U" discloses a silicone keypad that is easy to install, including a silicone keypad plate, a keypad body, and a positioning ring. The silicone keypad plate has uniformly distributed reinforcing silicone strips fixedly connected to its outer side. The silicone keypad plate has uniformly distributed positioning holes inside, and the silicone keypad plate is fixedly connected to uniformly distributed positioning rings through these holes. Reinforcing steel wires are fixedly connected inside the positioning rings, and uniformly distributed tension grooves are provided on one side of the positioning rings. Using this patented technology, the reinforcing silicone strips can easily reinforce and shape the outer side of the silicone keypad plate, making the silicone keypad plate more stable during installation and preventing damage. The positioning rings, tension blocks, and tension grooves facilitate the positioning of the silicone keypad plate for easy installation, and the reinforcing steel wires make the positioning rings more stable.

[0004] However, while the aforementioned patented technology increases the strength of the silicone panel to some extent by setting silicone strips, the silicone strips themselves are still made of silicone, and their strength is limited. Therefore, the overall strength improvement of the silicone panel is extremely limited. Although the aforementioned patented technology increases the positioning performance of the silicone panel to some extent by setting positioning rings, tensioning blocks, and tensioning grooves, the positioning rings, tensioning blocks, and tensioning grooves are still made of silicone, and their strength is limited. Therefore, the overall rigidity improvement of the silicone panel is extremely limited. This still results in low assembly accuracy of the controller, and the silicone deforms, causing some buttons to fail to reliably transmit electrical signals when pressed. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a molding panel manufacturing process, a molding panel, and a controller.

[0006] The present invention is achieved through the following technical solutions.

[0007] This invention provides a molding panel manufacturing process, comprising the following steps: Step 1: Provide a mold, which includes an upper mold and a lower mold. The surface of the lower mold is provided with a number of positioning platforms, and the surface of the upper mold is provided with a number of positioning grooves. When the upper mold and the lower mold are closed, each positioning platform extends into the corresponding positioning groove, and the bottom surface of the upper mold and the top surface of the lower mold surround each other to form a cavity. Step 2: Provide a substrate, the surface of which is provided with a plurality of positioning holes; Step 3: First, overlap the bottom surface of the base body with the surface of the lower mold, and make each positioning platform pass through the corresponding positioning hole. Then, close the upper mold and the lower mold together. Step 4: Inject the molten insulator into the cavity. When the insulator solidifies, the positioning groove and the corresponding position of the positioning platform form a button post. The insulator and the substrate fuse to form a molded panel. Then, separate the upper mold and the lower mold and remove the molded panel.

[0008] The molding panel manufacturing process also includes the following steps: Step 1: When performing Step 2, provide several light-blocking components; Step 2: When performing Step 3, first fit the light-blocking component into the positioning hole; Step 3: During step four, the light-blocking component is also integrated into the molded panel.

[0009] The light-blocking component is made of non-metallic material.

[0010] The substrate is made of metal.

[0011] The insulator is made of silicone.

[0012] In addition, the present invention also provides a molded panel, including a substrate and an insulator. The surface of the substrate is provided with a plurality of positioning holes, and the surface of the insulator is provided with a plurality of button posts. The bottom surface of the insulator is superimposed on the surface of the substrate, and the positioning holes correspond one-to-one with the button posts.

[0013] In addition, the present invention also provides a controller, including a molded panel, a circuit board and a housing as described above. The surface of the circuit board is provided with a plurality of electronic switches. The circuit board, the molded panel and the housing are respectively fastened together with fasteners. The molded panel is also stacked on the surface of the circuit board, and the button post is disposed above the electronic switches.

[0014] The controller also includes a housing cover, which is fastened to the housing base with fasteners. The housing cover, the molded panel, and the circuit board are arranged in a top-to-bottom order, and the button post also penetrates through the housing cover.

[0015] The fastener is a bolt or a rivet.

[0016] The beneficial effects of this invention are as follows: By employing the technical solution of this invention, a rigid substrate and a flexible insulator are directly fused together through a molding process, so that the bottom surface of the prepared molded panel has the rigidity of the substrate, while the surface still has the flexibility of the insulator. When assembling the molded panel with the printed circuit board, it is convenient for the user to position and assemble the molded panel, so that the button posts on the molded panel can be accurately aligned with the electronic switches on the printed circuit board, reducing assembly errors, preventing large deformation of the silicone panel, ensuring normal button function, and enabling the corresponding buttons to reliably transmit electrical signals through user pressing operations.

[0020] like Figures 1 to 2 As shown, the present invention provides a molding panel manufacturing process, including the following steps: Step 1: Provide a mold, which includes an upper mold and a lower mold.

[0023] Furthermore, the light-blocking element 4 is preferably made of a non-metallic material. The substrate 1 is made of a metallic material. The insulator 2 is made of silicone.

[0024] In addition, the present invention also provides a molded panel, including a substrate 1 and an insulator 2.
