Description

Technical Field

[0001] This utility model relates to the field of industrial automation drive technology, and in particular to a modular mounting structure for a drive display area. Background Technology

[0002] A driver is a device in the field of industrial automation equipment that has display and operation functions. Its core includes a display area (equipped with silicone buttons and a display panel) and human-machine interaction components. It is used to meet the needs of parameter display and function operation in industrial scenarios, and needs to be adapted to the mass production scenarios of automated production lines to achieve efficient assembly and stable operation.

[0003] In the existing technology, the silicone buttons in the driver display area are mainly installed with the display panel using two different methods, both of which have significant drawbacks: (I) Overall Embedded Installation Solution The driver's main housing has a pre-drilled groove for the display area. First, the silicone button is placed into the display PCBA, and the display panel is secured to the main housing using adhesive or clips. Then, the main housing is fitted onto the display PCBA. In this design, the silicone button's installation travel is equal to the main housing depth (typically 110-150mm). Because the button is soft and lacks precise positioning, it is prone to tipping over or wrinkling during assembly, leading to misalignment with the display panel's trigger point. Furthermore, the deep cavity of the main housing obstructs the visual positioning system, making it difficult for the robotic arm to stably grip the button, resulting in an automated assembly yield rate of less than 70%.

[0004] (II) Pre-adhesive assembly installation scheme The silicone buttons are pre-attached to the back of the main plastic shell display area using adhesive, and then the entire assembly is embedded into the display PCBA. The installation travel is still 110-150mm, and the adhesion accuracy depends on manual labor. When the assembly is embedded, the buttons are prone to falling off due to friction from the edge of the main plastic shell. The adhesive is easily affected by temperature and is prone to failure. The buttons are easy to fall off during use, and manual adjustment is required. The assembly time for a single piece is ≥30 seconds, which cannot meet the needs of mass production.

[0005] In summary, existing solutions suffer from low assembly yield, poor efficiency, and insufficient stability due to issues such as "long-stroke installation," "lack of precise positioning," and "reliance on adhesive backing," which restricts the production and reliability of the drive.

[0006] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a modular installation structure for the display area of ​​the driver, which solves the technical problems of soft silicone buttons in existing drivers being prone to displacement during long-stroke installation and difficult to adapt to automated production lines.

[0008] The above objectives are achieved through the following technical solutions: A modular mounting structure for a driver display area includes an independent display area unit, a silicone button, a display panel, and a driver housing. The independent display area unit is part of the driver housing, and the two are assembled either by detachable installation or integral molding. The independent display area unit serves as a pre-installed carrier for the silicone button and the display panel. The front of the independent display area unit has a silicone button mounting groove for accommodating the silicone button, and the bottom of the silicone button mounting groove has a positioning post. The back of the silicone button has a positioning hole adapted to the positioning post, and the silicone button is embedded in the silicone button mounting groove through the cooperation of the positioning hole and the positioning post. The edge of the independent display area unit has a snap-fit ​​groove, and the edge of the display panel has a snap-fit ​​groove adapted to the snap-fit ​​groove. The display panel is fixed to the independent display area unit by the snap-fit ​​connection between the snap-fit ​​groove and the snap-fit ​​groove, and the back of the display panel presses against the non-trigger area of ​​the silicone button. The driver housing has an adapter structure corresponding to the independent display area unit, which is an installation position when detachable and an integral carrier structure when integrally molded.

[0009] Furthermore, the groove depth of the silicone button mounting groove is ≤5mm, and the gap between the groove contour of the silicone button mounting groove and the contour of the silicone button is ≤0.1mm.

[0010] Furthermore, the edge of the silicone button is provided with a flange, and the edge of the groove of the silicone button mounting slot is provided with a groove that matches the flange. The flange is inserted into the groove to achieve the pre-fixation of the silicone button.

[0011] Furthermore, the display panel is made of PC material, and there are 6 clips, which are evenly distributed along the edge of the display panel.

[0012] Furthermore, the display panel has a through-hole gap corresponding to the position of the silicone button trigger end, and the diameter of the through-hole gap is larger than the diameter of the silicone button trigger end.

[0013] Furthermore, the number of positioning posts is at least two, and the two positioning posts are symmetrically arranged at the bottom of the silicone button mounting groove. The diameter of the positioning posts is 1.8-2.2mm and the height is 0.8-1.2mm.

[0014] Furthermore, the groove depth of the silicone button mounting groove is 1.5mm, the fastening stroke when the display panel and the independent unit of the display area are fastened together is 1.4mm, and a pressure of 4.8-5.2N needs to be applied during the fastening process.

[0015] Furthermore, if the display area independent unit and the driver main housing are detachably installed, an auxiliary positioning post is provided in the mounting position of the driver main housing, and an auxiliary positioning hole adapted to the auxiliary positioning post is provided on the back of the display area independent unit.

[0016] Furthermore, if the independent display area unit and the driver housing are detachably installed, they are fixed together by screws or clips. When screws are used, the mounting position of the driver housing has four screw holes, and the tightening torque of the screws is 0.4-0.6N. m.

[0017] Furthermore, the independent display area unit is made of PC+ABS material; the detachable type is injection molded, and the integrated type is made of the same material as the driver housing; the silicone buttons are made of silicone material with a Shore hardness of 40-70HA, and the thickness of the display panel is 1.8-2.2mm.

[0018] This utility model provides a modular mounting structure for a driver display area. This modular mounting structure reduces the silicone button installation stroke to ≤5mm to prevent misalignment, improving the assembly yield of automated production lines to 99% and shortening the assembly time per unit to within 15 seconds. It replaces adhesive backing with a mechanical structure to prevent button detachment, and the modular design is compatible with mass production of drivers. This effectively solves the problems of easy misalignment, poor automation compatibility, low efficiency, and insufficient stability associated with long-stroke silicone buttons in existing technologies. Specific effects are as follows: 1. Significantly reduced installation travel: The installation travel of silicone buttons has been reduced from 110-150mm to 1.5mm, avoiding the offset and wrinkling of soft buttons during long travel periods, and improving the assembly yield rate from 70% to 99%. 2. Strong automation compatibility: The display area is an independent unit without deep cavity obstruction, the vision positioning system can accurately identify the mounting slot, the robotic arm can directly complete the button placement, and the automated assembly efficiency is improved by 100% (single piece time is reduced from 30 seconds to 15 seconds). 3. High positioning accuracy: The zero-gap fit between the mounting groove contour and the button + dual positioning of positioning pins / holes ensures that the alignment error of the trigger point between the button and the display panel is ≤0.1mm, solving the tediousness of traditional manual adjustment; 4. Good structural stability: The snap-fit ​​connection of the display panel can keep the buttons pressed tightly for a long time, avoiding the problem of falling off due to the failure of the adhesive backing, and extending the service life to 5 years (the traditional solution is 2 years). 5. Modular design: The display area can be reused in similar button products, making it suitable for mass production. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] like Figures 1-4 As shown, this solution provides a modular mounting structure for the driver display area. Through a structural design of "independent display area unit (part of the main housing) + pre-formed mounting slot + snap-fit ​​step-by-step assembly," it achieves short-stroke, high-precision assembly. The specific structure and connection relationships are as follows: 1. Core components and their connections like Figure 1 and 2 As shown, the driver consists of a driver housing 5 and a driver main shell 4 connected together to form a cavity for mounting functional components, such as the display module 6. The independent display area unit 1 corresponds to the position of the display module 6.

[0023] Independent display area unit 1: This is part of the driver main housing 4, and there are two assembly methods: (1) Detachable type: PC+ABS material injection molding, with a silicone button mounting groove 101 on the front (to accommodate silicone button 2), and symmetrical positioning posts 102 (at least 2, diameter 1.8-2.2mm, height 0.8-1.2mm) at the bottom of the groove, and a buckle groove 103 on the edge (to be adapted to the buckle 301 of the display panel 3). (2) One-piece molding: Made of the same material as the driver housing 4 (PC+ABS), it is integrally molded by injection molding. The connecting parts can be provided with arc transition to enhance strength. The front structure is consistent with the detachable type. Its core function is to serve as a pre-installed carrier for the silicone button 2 and the display panel 3 to achieve short-stroke installation.

[0024] Silicone button 2: Made of silicone with a Shore hardness of 70HA, with a positioning hole 201 on the back that matches the positioning post, and a flange 202 on the edge; it is fitted into the silicone button mounting groove 101 through the "positioning hole-positioning post" cooperation, and the flange 202 is inserted into the groove 104 of the mounting groove to achieve pre-fixation and avoid assembly displacement.

[0025] Display panel 3: PC material (1.8-2.2mm thick), with 6 evenly spaced clips along the edge; it is fixed to the independent unit by "clip-clip groove" fastening, and the non-trigger area of ​​the silicone button 2 is pressed against the back to achieve final button fixation; a through hole gap 302 (slightly larger hole diameter) is provided at the corresponding button trigger end to ensure trigger sensitivity.

[0026] Driver main housing 4: When detachable, it is provided with a mounting position (including auxiliary positioning post, which cooperates with the auxiliary positioning hole on the back of the independent unit) for fixing the pre-installed components; when integrally molded, it is integrated with the independent unit 1 of the display area and directly serves as the pre-installed carrier.

[0027] 2. Assembly process (adapted to automated production lines), such as Figure 2-4 As shown (1) Silicone button assembly: The robotic arm grabs the silicone button 2, aligns the positioning hole 201 with the positioning post 102 of the independent unit 1 of the display area, and vertically inserts it into the silicone button mounting groove 101 (stroke = groove depth ≤ 5mm, preferably 1.5mm). The flange 202 is inserted into the groove 104 to complete the pre-fixation; without deep cavity obstruction, the visual positioning system can accurately identify.

[0028] (2) Display panel assembly: The robotic arm grabs the display panel 3, aligns the buckle 301 with the buckle slot 103 of the independent unit 1 of the display area, applies a pressure of 4.8-5.2N (1.4mm fastening stroke) to complete the fastening, and presses the silicone button 2 on the back of the display panel 3 to form a pre-assembled component of "independent unit + button + panel".

[0029] (3) Overall assembly (disassembly only): The robotic arm aligns the auxiliary positioning holes of the pre-assembled components with the auxiliary positioning posts of the main housing mounting position, and then uses screws (tightening torque 0.4-0.6N) to assemble the components. (m) or snap fasteners are used to secure the assembly; this step is not required when the piece is molded as a single unit.

[0030] 3. Work Process When the driver is running, the user presses the trigger end of the silicone button 2, and the silicone button 2 deforms and passes through the through hole gap 302 of the display panel 3, triggering the PCBA contact 601 on the display module 6 to realize the operation; the positioning structure presses firmly against the display panel 3 to ensure that the silicone button 2 does not shift or fall off.
