Description

Technical Field

[0001] The utility model belongs to the technical field of controller shell structures, in particular to an andon shell for lean production. Background Art

[0002] Lean production is a production management method. The corresponding andon housing has built-in control instructions integrated into the PCB and is wirelessly connected to the control receiving instruction unit via an antenna. This housing is small and the control buttons are compact. The front and rear shells are connected and fixed with bolts to complete the installation. The interior is small except for the silicone button and PCB.

[0003] In actual use, although this type of andon housing is small, portable and easy to use, it still has the following defects: the PCB lacks an effective protective structure. Although there is a silicone button at one end, the outside and the other end lack protection. When the andon housing falls and is subjected to external pressure, the damage may cause damage to the PCB; the sealing is insufficient. In order to ensure the installation of button batteries, this type of andon housing generally does not consider waterproof and moisture-proof properties. Water and moisture will enter the internal cavity through the button part and the joint between the front and rear shells. If it is in a humid state or comes into contact with water for a long time, it will cause damage to the PCB. Therefore, we propose a lean-produced andon housing. Utility Model Content

[0004] The purpose of the utility model is to provide a lean-produced andon housing to solve the problem of lacking an effective protective structure for the PCB board. Although there is a silicone button at one end, the outer side and the other end lack protection. When the andon housing falls and is subjected to external pressure, the damage may cause damage to the PCB board; the sealing is insufficient. In order to ensure the installation of button batteries, this andon housing generally does not consider waterproof and moisture-proof properties. Water and moisture will enter the internal cavity through the button part and the joint between the front and rear shells. If it is kept in moisture or comes into contact with water for a long time, it will cause damage to the PCB board. Technical problems.

[0032] Example:

[0033] like Figs. 1-3 As shown, the lean-produced andon housing of this embodiment includes a base shell 1, a front shell 2 and a PCB3, and the PCB3 is built into the base shell 1 and the front shell 2; when installing the base shell 1 and the front shell 2, since the two are provided with corresponding posts 11 and sockets 24, the bolts are fastened from the outside of the base shell 1 to the posts 11 and the sockets 24 to fix them, which is an existing conventional installation method.

[0034] The silicone button 4 is integrally formed with a protrusion 41 on the side facing the face shell 2, and the protrusion 41 is clamped in the button slot 23 formed through both ends of the face shell 2.

[0035] In summary, the silicone button 4, the silicone protective edge 5, and the silicone bottom pad 6 are tightly attached in the cavity formed by the bottom shell 1 and the face shell 2, thereby embedding the PCB 3, avoiding damage to the PCB 3 due to external forces, and preventing internal shaking.

[0036] The inner embedding groove 21 is provided on the outer side of the face shell 2, and the plastic sticker 7 is bonded in the inner embedding groove 21. The bottom shell 1 and the face shell 2 are clamped, and the sealing pad 8 is bonded in the clamping groove 22 provided on the inner side of the face shell 2. The sealing pad 8 is bonded in the clamping groove 22 provided on the inner side of the face shell 2, ensuring that the bottom shell and the face shell 2 are tightly sealed when clamped. The size of the plastic sticker 7 is adapted to the inner embedding groove 21, and the plastic sticker 7 is bonded to the inner embedding groove 21 by waterproof glue, thereby being attached to the protrusion 41 to form a waterproof barrier, preventing water, moisture, and dust from entering the inside of the bottom shell 1 and the face shell 2 through the protrusion 41.

[0037] The silicone button 4 is integrally formed with a protrusion 41 on the side facing the face shell 2, and the protrusion 41 is clamped in the button slot 23 formed through both ends of the face shell 2.

The reserved slot and the antenna head cover provide smooth connection and additional protection for the antenna.

[0039] In summary, the lean production of the light shell of the present embodiment effectively solves the shortcomings of the traditional light shell in the protection of the PCB 3 and the waterproof and moisture-proof aspects. The tight fit of the silicone button 4, the silicone protective edge 5, and the silicone bottom pad 6 provides all-round protection for the PCB 3. The cooperation of the plastic sticker 7 and the sealing pad 8 ensures the waterproof and moisture-proof performance of the inside of the shell. The design of the plug 11, the socket 24, the protrusion 41, and the button slot 23 enhances the structural stability of the shell. These designs make the light shell of the present embodiment more reliable and durable, and suitable for various lean production environments.
