Description

Technical Field

[0001] The invention relates to a production and assembly auxiliary device, in particular to a household appliance production and assembly auxiliary system. Background Art

[0002] The structure of household appliances is generally divided into a shell part, a mechanical structure, and electronic components. The shell part is generally a plastic part, which is injection molded and then used for production and assembly after a dewatering process. The mechanical structure part has many components and the assembly process is complicated. Therefore, in order to improve the assembly efficiency, it will be divided into multiple sub-modules for assembly. Finally, the shell part, multiple sub-module mechanical structures and electronic components are assembled in a unified manner. This assembly mode is generally called a modular assembly process. Such an assembly process can decompose the originally cumbersome assembly process into multiple sub-processes, and all sub-processes can be carried out simultaneously, so the production efficiency can be significantly improved in the same time. However, in contrast, the number of assembly stations has also increased a lot, so how to efficiently dispatch the semi-finished products produced by each assembly station has become an urgent problem to be solved in the electrical appliance production industry. Summary of the invention

[0003] The present invention provides a household appliance production and assembly auxiliary system, which solves the problem in the prior art that a modular assembly process needs to solve how to efficiently schedule semi-finished products produced by multiple stations.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: A household appliance production and assembly auxiliary system comprises a plurality of flow plates, a plurality of linear flow tables and two reversing flow tables;

[0005] The linear flow turntable is composed of a bracket, a longitudinally distributed horizontal conveying component and a limiting component. The flow plate can be placed flat on the horizontal conveying component. The horizontal conveying component can push the flow plate to move to one side of the limiting component. The limiting component includes a lifting block and a lifter that drives the lifting of the lifting block. When the lifting block is lowered, the linear flow turntable can push the flow plate on it backward horizontally. When the lifting block is raised and reset, the flow plate on it will be limited to a position that abuts against the lifting block.

[0006] The reversing flow table is additionally provided with a transverse guide rail, a roller rolling on the guide rail, and a reversing power assembly driving the roller to roll on the basis of the linear flow table. The roller is provided at the bottom of the bracket. The distribution direction of the transverse guide rail is perpendicular to the conveying direction of the horizontal conveying assembly. The reversing power assembly is provided on the bracket. The horizontal conveying assembly on the reversing flow table can convey the flow plate to each other with the horizontal conveying assembly on the linear flow table.

[0007] The straight flow turntables are divided into two groups and placed end to end in a longitudinal direction to form a first flow line and a second flow line that are distributed in reverse parallel. The two reversing flow turntables are respectively arranged at the two ends of the two flow lines.

[0008] Each linear flow table in the present invention can correspond to an installation station or a loading and unloading station, and the flow plate is used to carry the assembly parts. During the operation of the present invention, the two reversing flow tables can be synchronously moved to the two ends of the first flow line or the second flow line. The number of flow plates is one more than the number of linear flow tables. When the two reversing flow tables move to the two ends of the first flow line, each linear flow table on the first flow line carries a flow plate, and the reversing flow table at the front end also carries a flow plate. Therefore, the reversing flow table and all the linear flow tables on the first flow line synchronously push the flow plates they carry backwards, so that these flow plates can be synchronously moved backwards by one station, and then, the two reversing flow tables synchronously reverse to the two ends of the second flow line and push in the opposite direction, so that the flow plates on the second flow line can also move by one station. In this way, the cycle is repeated, and finally the closed-loop flow of the flow plates along the first flow line and the second flow line is realized.

[0009] Since the flow plates on the straight flow table and the reversing flow table need to be circulated synchronously, the residence time of the flow plates on the straight flow table and the reversing flow table is the same, which requires the installation process of each installation station to be adjusted to make the installation time of each station as consistent as possible, so as to improve the assembly efficiency as much as possible. The present invention is used to connect multiple modular assembly stations originally used for the production of household appliances in series, and has an efficient fixed scheduling mode.

[0010] By using the assembly method of the assembly line of the present invention to produce household appliances, the time required for installation at a single workstation can be significantly reduced. The time it takes to produce a sofa on the entire assembly line is the installation time of a single workstation, so the production efficiency of the sofa can be significantly improved. At the same time, the installation procedures required by the workers at a single workstation are significantly reduced, the technical requirements for the workers are also greatly reduced, and the training time for the workers can be significantly reduced.

[0011] Furthermore, the limit assembly also includes a sensor disposed on the bracket, the sensor being close to one side of the lifting block, and the sensor being used to detect whether the flow plate passes through. The sensor may be a photoelectric sensor or a proximity sensor. Since the limit assembly in the present invention is used to control the stop position of the flow plate, it is necessary to install a sensor to know in advance the sliding position of the flow plate to be positioned, so as to facilitate timely and accurate triggering of the lifting block's rising procedure.

[0012] Furthermore, an elastic member is connected between the lifting block and the lifter. The advantage of this arrangement is that even if the previous flow plate on the flow table has not completely left the top of the lifting block, the lifter can generate a lifting action in advance. When the lifting block abuts against the flow plate above, the elastic member can adaptively deform to prevent the flow plate from being lifted up. After the flow plate completely leaves, the elastic member rebounds to make the lifter rise to a high position, so that the next flow plate that arrives can be limited. This design can greatly increase the window time for triggering the lifter and improve the redundancy of the entire system operation.

[0013] Furthermore, vertically distributed guide blocks are provided on both sides of the lifting block, and guide grooves are provided on the bracket to slide with the guide blocks. Since the lifting block needs to limit the flow plate in the horizontal direction, it will be subjected to horizontal thrust, so it is necessary to increase the horizontal shear strength of the lifting block by matching the guide grooves with the guide blocks.

[0014] Furthermore, the top of the lifting block is rotatably equipped with a guide wheel, and the top and rear side of the lifting block are set at an angle. The guide wheel is used to roll with the bottom surface of the flow plate to reduce wear between the two. The top and rear side of the lifting block are set at an angle, which is designed to avoid excessive friction between the flow plate and the lifting block when they are separated.

[0015] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The flow plate in the present invention can perform closed-loop flow along the first flow line and the second flow line, and each linear flow table corresponds to an installation station, so that each installation station can be connected in series, with an efficient and fixed scheduling mode, which is conducive to improving the efficiency of production and assembly.

[0027] Example 1: See Figure 1 , Figure 2 , Figure 3 and Figure 5 , a household appliance production and assembly auxiliary system, comprising 9 flow plates 100, 8 straight flow tables 200 and two reversing flow tables 300;

[0028] The linear flow turntable is composed of a bracket 10, a longitudinally distributed horizontal conveying component 20 and a limiting component 30. The flow plate can be placed flat on the horizontal conveying component. The horizontal conveying component can push the flow plate to move to one side of the limiting component. The limiting component includes a lifting block 31 and a lifter 32 that drives the lifting thereof. The lifter is specifically a cylinder. When the lifting block is lowered, the linear flow turntable can push the flow plate thereon backward horizontally. When the lifting block is raised and reset, the flow plate thereon will be limited to a position that abuts against the lifting block.

[0029] The reversing flow table is provided with a transverse guide rail 40, a roller 50 rolling on the guide rail, and a reversing power assembly driving the roller to roll on the basis of the linear flow table. The roller is provided at the bottom of the bracket. The distribution direction of the transverse guide rail is perpendicular to the transmission direction of the horizontal transmission assembly. The reversing power assembly is provided on the bracket. The horizontal transmission assembly on the reversing flow table can transmit the flow plate to the horizontal transmission assembly on the linear flow table. The reversing power assembly is composed of a second motor and a transmission chain. The transmission chain is used to drive the output shaft and roller connected to the second motor.

[0030] The straight flow turntables are divided into two groups and arranged end to end in a longitudinal direction to form a first flow line 400 and a second flow line 500 which are distributed in reverse parallel. Two reversing flow turntables are respectively arranged at both ends of the two flow lines.

[0031] In this embodiment, each linear flow table can correspond to an installation station or a loading and unloading station, and the flow plate is used to carry the assembly parts. During the operation of this embodiment, the two reversing flow tables can be synchronously moved to the two ends of the first flow line or the second flow line. The number of flow plates is one more than the number of linear flow tables. When the two reversing flow tables move to the two ends of the first flow line, each linear flow table on the first flow line carries a flow plate, and the reversing flow table at the front end also carries a flow plate. Therefore, the reversing flow table and all the linear flow tables on the first flow line synchronously push the flow plates they carry backwards, so that these flow plates can be synchronously moved backwards by one station, and then the two reversing flow tables synchronously reverse to the two ends of the second flow line and push in the opposite direction, so that the flow plates on the second flow line can also move one station. In this way, the cycle is repeated, and finally the closed-loop flow of the flow plates along the first flow line and the second flow line is realized.

[0032] Since the flow plates on the straight flow table and the reversing flow table need to be circulated synchronously, the residence time of the flow plates on the straight flow table and the reversing flow table is the same, which requires the installation process of each installation station to be adjusted to make the installation time of each station as consistent as possible, so as to improve the assembly efficiency as much as possible. This embodiment is used to connect multiple modular assembly stations originally used to produce home appliances in series, and has an efficient fixed scheduling mode.

[0033] By using the assembly line assembly method of this embodiment to produce home appliances, the time required for installation at a single workstation can be significantly reduced. The time it takes to produce a sofa on the entire assembly line is the installation time of a single workstation, so the production efficiency of sofas can be significantly improved. At the same time, the number of installation procedures required by workers at a single workstation is significantly reduced, the technical requirements for workers are also greatly reduced, and the training time for workers can be significantly reduced.

[0034] The limit assembly also includes a sensor disposed on the bracket, the sensor is close to one side of the lifting block, and the spacing is between 5 and 15 centimeters. The sensor can be used to detect whether a flow plate passes. The sensor is specifically a proximity sensor. Since the limit assembly in this embodiment is used to control the stop position of the flow plate, it is necessary to install a sensor to know in advance the sliding position of the flow plate to be positioned, so as to trigger the lifting block's rising procedure in a timely and accurate manner.

[0035] See Figure 6 , Figure 7 and Figure 8, an elastic member 34 is connected between the lifting block and the lifter. The advantage of this arrangement is that even if the previous transfer plate on the transfer table has not completely left the top of the lifting block, the lifter can generate a lifting action in advance. When the lifting block abuts against the upper transfer plate, the elastic member can deform adaptively to prevent the transfer plate from being lifted up. After the transfer plate completely leaves, the elastic member rebounds to make the lifter rise to a high position, so that the next transfer plate that arrives can be limited. This design can greatly increase the window time for triggering the lifter and improve the redundancy of the entire system operation;

[0036] See Figure 7 , vertically distributed guide blocks 35 are provided on both sides of the lifting block, and the bracket is provided with guide grooves 36 that slide with the guide blocks. Since the lifting block needs to limit the flow plate in the horizontal direction, it will be subjected to horizontal thrust, so it is necessary to form a cooperation between the guide groove and the guide block to increase the horizontal shear strength of the lifting block.

[0037] See Figure 6 The top of the lifting block is rotatably equipped with a guide wheel 37, and the top and rear side of the lifting block are set at an angle. The guide wheel is used to roll with the bottom surface of the flow plate to reduce wear between the two. The top and rear side of the lifting block are set at an angle. This design is to avoid excessive friction between the flow plate and the lifting block when they are separated.

[0038] See Fig. 9 The horizontal transmission assembly includes a plurality of transmission wheels 21 arranged in an array on a bracket and a transmission assembly driving the transmission wheels to rotate synchronously, and the transmission wheels are all arranged at the same height. The transmission assembly includes a first motor 22, four rotating shafts 23 and four pulley assemblies 24, the pulley assembly is connected between any two rotating shafts or between the rotating shaft and the output shaft of the first motor, the pulley assembly is a belt pulley assembly or a chain pulley assembly, and a transmission wheel is arranged on the rotating shaft.

[0039] Benjian Figure 4 In the embodiment, two concave tracks 101 are formed on the bottom surface of the flow plate from front to back and adapted to the outer contour of the driving wheel, which play a role in guiding the flow of the flow plate.

[0040] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
