Description

Technical Field

[0001] This invention relates to the field of mechanical component assembly technology, and in particular to a bimetallic strip assembly device for door locks. Background Technology

[0002] Currently, during the assembly of washing machine cabinet door locks, the bimetallic strip on the washing machine cabinet door, as a key temperature control component, needs to be installed precisely. When installing the metal strip, it is necessary to place the metal strip in the lock box with the predetermined orientation.

[0003] Currently, the industry generally uses manual or semi-automatic methods to complete the orientation placement of bimetallic strips. Manual sorting is inefficient and prone to mis-installation due to human factors. With the upgrading of intelligent manufacturing, the combination of vibratory feeder feeding and robotic gripping has become the mainstream solution. However, the posture recognition problem caused by the material difference of bimetallic strips has not been effectively solved. The robotic arm cannot identify the orientation of the metal strips, which makes it easy to make errors during the transfer of metal strips, affecting the installation efficiency of bimetallic strips and thus reducing the production efficiency of washing machine cabinet door locks.

[0004] In response to the aforementioned technologies, there is an urgent need to design and develop a bimetallic strip assembly device for door locks. During the process of the robotic arm grasping the metal strip, the orientation of the metal strip can be identified and adjusted so that the metal strip can be transported in the correct orientation, thereby improving the production efficiency of washing machine cabinet door locks. Summary of the Invention

[0005] In order to ensure that the metal sheets are transported in the correct orientation and to improve the production efficiency of washing machine cabinet door locks, this application provides a bimetallic strip assembly device for door locks.

[0006] The bimetallic strip assembly equipment for door locks provided in this application adopts the following technical solution: A bimetallic strip assembly device for door locks includes a first vibratory feeder for sorting the bimetallic strips and a robotic arm for transporting the bimetallic strips. The robotic arm is movably mounted on a frame, which is equipped with a conveying mechanism for conveying a lock box bottom, a control mechanism for adjusting the orientation of the bimetallic strips, an installation mechanism for mounting the bimetallic strips to the lock box bottom, a combination mechanism for mounting the lock box bottom to a temperature sensor, an assembly mechanism for mounting the bimetallic strips, a contact bridge, and a lock box top, and a sorting mechanism for classifying qualified and unqualified products. The control mechanism includes a first identification probe for identifying the orientation of the bimetallic strips, a conveyor belt for conveying the bimetallic strips, and an adjustment seat for adjusting the angle of the bimetallic strips. The top surface of the adjustment seat has a selection hole, and a guide plate is disposed within the selection hole. A gap is left between the guide plate and the inner wall of the selection hole for the bimetallic strips to pass through. The adjustment seat is mounted on the conveyor belt.

[0007] By adopting the above technical solution, the robotic arm is movably mounted on the frame, and the adjusting seat is mounted on the conveyor belt. A selection hole is opened on the top surface of the adjusting seat, and a guide plate is installed inside the selection hole. A gap is left between the guide plate and the inner wall of the selection hole for a metal sheet to pass through. During the process of installing the metal sheet into the lock box bottom, the conveying mechanism transports the lock box bottom to a position close to the conveyor belt, driving the robotic arm to remove the metal sheet from the first vibrating plate. The first identification probe identifies the orientation of the metal sheet at this time. If the first identification probe identifies the metal sheet orientation correctly, the robotic arm is controlled to place the metal sheet on the conveyor belt and transport it to the installation mechanism, allowing the installation mechanism to complete the installation of the metal sheet into the lock box bottom. If the first identification probe identifies the metal sheet orientation as reversed, the robotic arm is controlled to... The metal sheet is placed into the selection hole by hand. The metal sheet moves downward through the gap. After the lower end of the metal sheet contacts the conveyor belt, it is driven by the conveyor belt and moves towards the installation mechanism. Then the metal sheet continues to fall and flips over. The conveyor belt transports the metal sheet to the installation mechanism after it has been flipped to the required state. The installation mechanism completes the installation of the metal sheet and the lock box bottom box. By identifying and adjusting the orientation of the metal sheet, it ensures that the metal sheet can be transported in the correct orientation, improving the production efficiency of the washing machine cabinet door lock. The assembly mechanism installs the lock box bottom box and the temperature sensor. The assembly mechanism installs the metal sheet, contact bridge, and lock box top box. The sorting mechanism sorts qualified and unqualified products. The overall installation process is quick and convenient, saving manpower.

At this time, the material is conveyed... The conveyor belt stops conveying the lock box bottom. The rodless cylinder drives the transverse slide to slide, bringing the clamping seat closer to the lock box bottom on the transport seat. The longitudinal guide cylinder drives the slide to slide, bringing the clamping seat closer to the lock box bottom and clamping it. The rodless cylinder drives the transverse slide to slide, bringing the clamping seat along the groove of the material conveyor belt to the appropriate position. At this time, the lifting cylinder drives the transport seat to descend to the material conveyor belt outlet. The material conveyor belt continues to convey the lock box bottom to the transport seat. The longitudinal guide cylinder then drives the slide to slide, moving the clamping seat away from the material conveyor belt. Under the limiting effect of the groove of the material conveyor belt, the lock box bottom is placed on the material conveyor belt. The conveying is repeated to facilitate the equidistant conveying of the lock box bottom according to requirements.

When the second identification probe accurately identifies the contact bridge installation position, the turntable continues to convey the lock box base to below the screw-driving machine. The screw-driving machine connects the contact bridge and the lock box base with screws and then continues to convey it to the transfer assembly.

[0069] The implementation principle of the bimetallic strip assembly equipment for door locks in this application embodiment is as follows: During the installation of the metal sheet into the lock box base, the conveying mechanism 4 transports the lock box base to a position close to the conveyor belt 51. The driven robot arm 3 then removes the metal sheet from the first vibrating plate 2. The first identification probe identifies the orientation of the metal sheet. If the first identification probe identifies the correct orientation, the robot arm 3 places the metal sheet onto the conveyor belt 51 and transports it to the installation mechanism 6, allowing the installation mechanism 6 to complete the installation of the metal sheet into the lock box base. If the first identification probe identifies the metal sheet as being in the opposite orientation, the robot arm 3 places the metal sheet into the selection hole 53. The metal sheet moves downwards through the gap, and after its lower end contacts the conveyor belt 51... Driven by conveyor belt 51, the metal sheet moves towards the installation mechanism 6. It then continues to fall and rotates in the correct orientation. Conveyor belt 51 transports the rotated metal sheet to the installation mechanism 6, where it installs the metal sheet onto the lock box base. By identifying and adjusting the orientation of the metal sheet, it ensures correct transport, improving the production efficiency of the washing machine cabinet door locks. Assembly mechanism 7 installs the lock box base and temperature sensor. Assembly mechanism 8 installs the metal sheet, contact bridge, and lock box top. Classification mechanism 9 classifies qualified and unqualified products. The overall installation process is quick, convenient, and saves manpower.
