[0050] 1. In an automatic device provided by the present invention, a push button switch product is pre-assembled into a bottom intermediate finished product, a middle component finished product and an upper component finished product through a bottom component assembly component, a middle component assembly component and an upper component assembly component, and then the middle component finished product and the upper component finished product are assembled into a semi-finished product through an intermediate assembly device, and the semi-finished product is transferred to the bottom component assembly component through the first turntable or the second turntable to complete the finished product assembly with the assembled bottom component finished product. Of course, the assembly process of the middle component finished product and the upper component finished product or the bottom intermediate finished product can be adjusted according to the product assembly requirements. The advantage of such a design is that the push button switch product is first divided into three parts and assembled simultaneously. In the respective assembly processes, the three parts are assembled into a finished product again through the coordination of the processes of the two turntables and the intermediate assembly device. The process with a long assembly time can be assembled separately, and after assembly, it is placed on the first turntable or the second turntable for the next assembly, reducing the waiting time of the process with a short assembly time, thereby shortening the total assembly time, improving the overall assembly progress, completing a product in a shorter assembly time, improving the assembly efficiency, and realizing automated assembly operation, which not only ensures the product assembly quality but also reduces the labor cost.

[0051] 2. An automatic device provided by the present invention is suitable for the assembly of push button switches. The parts of the push button switch are respectively assembled into a button assembly, an upper cover assembly and a base assembly through a button assembly assembly device, an upper cover assembly assembly device and a base assembly device. These three assembly devices can realize the assembly process of their respective components alone or in cooperation with two turntables. At the same time, the intermediate assembly assembles the transferred button assembly and base assembly into semi-finished products on one of the turntables. As the turntable continues to rotate, the base assembly assembly device only needs to assemble the assembled base assembly with the semi-finished product to obtain a finished push button switch. The processes between the various assembly devices are coordinated and orderly, so that the time required for assembling a single push button switch is shorter, which is beneficial to improving the degree of automated assembly of push button switch products and improving production efficiency.

[0052] 3. In an automatic device provided by the present invention, a button, a ratchet and a moving contact piece are assembled into a button assembly at an assembly station through a button assembly device, a ratchet assembly device and a moving contact assembly device arranged around a first turntable, and the button assembly is rotated along with the first turntable to one assembly end of the intermediate assembly device to facilitate reassembly with the upper cover assembly. When the plurality of assembly stations on the first turntable make circular motions, they will reach the button assembly device, the ratchet assembly device, the moving contact assembly device and the intermediate assembly device respectively, which can effectively coordinate the work between the connecting processes to ensure that the assembly process of the button assembly proceeds normally and continuously, and the entire assembly and transmission process can be completed without manual placement and intervention.

[0053] 4. In an automatic device provided by the present invention, the intermediate assembly device is arranged after the assembly process of the upper cover assembly device and the button device. When the upper cover assembly and the button assembly are respectively transferred to the two ends of the intermediate assembly device, the button assembly is assembled into the upper cover assembly through the cooperation of the assembly robot with the first guide rail and the second guide rail, thereby realizing the assembly process of the button semi-finished product, and the operation is accurate and reliable.

[0054] 5. In an automatic device provided by the present invention, the base component assembly device includes a base assembly mechanism, a second contact pin assembly mechanism and a spring assembly mechanism. These three mechanisms assemble the base, the contact pin and the spring into a base component outside the first turntable and the second turntable by themselves. According to the reasonable design of the assembly process, the semi-finished component is transferred to the base component assembly device along with the turntable during this process, and the base component assembly device assembles the base component into the semi-finished component to realize the finished product assembly of the push button switch. The front and rear assembly processes are coordinated and orderly without work interference, which can shorten the overall assembly progress.

[0055] 6. In an automatic device provided by the present invention, the first tentacle assembly mechanism and the second tentacle assembly mechanism respectively include a turntable, a stamping table, a pulling mechanism and a stamping mechanism. The pulling structure pulls the tape on the turntable into the stamping slot of the stamping table, and the stamping mechanism drives the stamping rod to squeeze the tentacle into the upper cover or the base, and the simultaneous installation of more than two tentacles is satisfied, thereby realizing the respective assembly processes of the upper cover and the first tentacle and the base and the second tentacle. The transmission and placement of these tentacles can be completed without manual intervention, thus avoiding the problems of tentacle falling, dislocation, etc. caused by manual operation. The assembly accuracy is high, and the stability of product assembly quality is improved.

[0056] 7. In an automatic device provided by the present invention, the spring assembly mechanism includes a feed block, a spring feeding plate and a receiving block. The spring falls from the feeding channel of the feed block into the receiving channel of the receiving block. When the receiving block moves from the receiving position to the loading position, the spring is transported to the discharging channel connected to the receiving channel. At this time, the spring is in a state to be assembled, and the spring is assembled to the base by driving the push rod to penetrate into the discharging channel. This structural setting realizes the orderly material distribution, conveying and assembly of spring parts, ensures the timeliness and reliability of assembly between the spring and the base, and the entire feeding and loading process is automated, the assembly position is accurate, and the operation is correct, which is conducive to improving the assembly efficiency of the product.

[0081] The intermediate assembly device 4 has its two ends connected to the first turntable 11 and the second turntable 12 respectively, and is used to assemble the finished bottom part of the bottom part assembly component 5 with the finished middle part of the middle part assembly component 2, or to assemble the finished middle part with the finished upper part of the upper part assembly component 3; the assembly end of the intermediate assembly device 4 is located on the first turntable 11 or the second turntable 12, and the first turntable or the second turntable continues to rotate, so that the semi-finished parts assembled by the intermediate assembly device 4 are assembled at the bottom part assembly component 5 or the upper part assembly component 3 with the finished bottom part or the finished upper part to complete the finished product assembly. Among them, the assembly end refers to the last assembly process of the assembly device. The assembly process of the middle piece finished product and the upper piece finished product or the bottom piece finished product can be adjusted according to the product assembly requirements. The advantage of this design is that the push button switch product to be assembled is first divided into three parts of the upper piece finished product, the middle piece finished product and the bottom piece finished product, which are assembled simultaneously. In the respective assembly processes, the three parts are combined and assembled into a finished product through the coordination of the processes of the two turntables and the intermediate assembly device. This greatly shortens the waiting time for each assembly process, thereby shortening the total assembly time, improving the overall assembly progress, completing the assembly time of a product in a shorter time, improving assembly efficiency, and realizing automated assembly operations, which both ensures the product assembly quality and reduces labor costs.

These three assembly devices can realize the assembly process of their respective components alone or in cooperation with two turntables. At the same time, the intermediate assembly device 4 assembles the transferred button assembly and base assembly into a semi-finished assembly on one of the turntables. As the turntable continues to rotate, the base assembly assembly device only needs to assemble the assembled base assembly with the semi-finished parts of the push button switch to obtain a finished push button switch.

The above three mechanisms assemble the base, contact pins and springs into a base assembly outside the first turntable and the second turntable, that is, independent assembly is achieved without passing through the first turntable 11 and the second turntable 12, and the assembly is carried out simultaneously with the upper cover assembly, the button assembly and the semi-finished product assembly. According to the reasonable design of the assembly process, finally, the finished product assembly of the push button switch can be realized by assembling the base assembly into the semi-finished product assembly by the base assembly assembly device 5.

This structural setting plays a role in guiding the movement of the assembly manipulator through the cooperation of the horizontal slide rail and the vertical slide rail, ensuring that the three assembly manipulators perform synchronous movement operations in the same direction, realizing the connection and cooperation of the front and rear assembly processes, that is, the three assembly manipulators complete the assembly of a base component each time they move, so that the base component on the second mounting seat is accurately and reliably assembled to the semi-finished product of the assembly station to obtain the finished push button switch, which can realize the continuous assembly process of the base component, the operation is accurate and reliable, and the assembly efficiency is improved.

[0096] In this embodiment, combined with Figure 7-11As shown, the first tentacle assembly mechanism 32 and the second tentacle assembly mechanism 52 have the same structural form, and both include a turntable 301, a punching table 302, a pulling mechanism 303 and a punching mechanism 304. Specifically, a roll 306 composed of a plurality of arranged tentacles is wound on the turntable 301, so as to facilitate the transportation of the tentacles to avoid dropping and losing; the punching table 302 is installed on the frame 1, and includes a strip groove suitable for connecting the roll 306 and at least one punching slot hole arranged on the strip groove and matching the tentacle, the punching slot hole is arranged opposite to the assembly station or the first mounting seat up and down, and the strip groove plays a limiting and guiding role on the roll; the pulling mechanism 303 is connected to the first mounting seat, and the first mounting seat ... The tape 306 and the punching table 302 are connected to pull the tape 306 into the punching slot hole along the strip groove; further, the punching mechanism 304 is arranged on the punching table 303, which includes at least one punching rod 305 suitable for penetrating into at least one of the punching slot holes, and the punching rod 305 pushes the contact pin to be installed into the upper cover or the base.

According to the above structural arrangement, the tape 306 on the turntable 301 is pulled into the stamping slot of the stamping table by the pulling mechanism 303, and the stamping mechanism 304 drives the stamping rod 305 to squeeze the contact pin into the upper cover or the base, and the simultaneous installation of two or more contact pins is satisfied, thereby realizing the respective assembly processes of the upper cover and the first contact pin and the base and the second contact pin. The transportation and placement of these contact pins can be completed without manual intervention, thus avoiding the problems of contact pin falling, dislocation, etc. caused by manual operation, with high assembly accuracy, thereby improving the stability of product assembly quality.

[0097] As a specific structural setting, the pulling mechanism 303 includes a cover plate arranged on the stamping table, a pulling cylinder 3031 and a pawl assembly, the pawl assembly includes a moving block 3032 driven by the pulling cylinder and movably arranged on the cover plate along the extension direction of the strip groove, and a pawl 3033 hinged on the moving block, the tip of the pawl 3032 is penetrated into a plurality of squeezing holes 3034 arranged at intervals on the roll 306, and drives the roll to move toward the side of the stamping slot hole during the movement of the moving block; further settings, such as Fig.15As shown, the upper end of the pawl 3033 is rotatably set in the rotating hole inside the moving block through a hinge shaft, and the lower end thereof is a tip extending out of the moving block. The tip of the pawl 3033 is provided with a guiding bevel that cooperates with the pushing hole for sliding contact. When following the moving block 3032 to move toward the side of the stamping slot hole, the tip is pressed against the pushing hole to pull the roll 306 forward, and when following the moving block 3032 to move away from the stamping slot hole, the tip slides out of the pushing hole through the guiding bevel. This process does not play a pushing or pulling role on the roll 306, so that the reciprocating motion is performed to realize the conveying effect of the roll on the stamping table.

When the receiving block 532 is in the loading position, the driving push rod 536 penetrates into the receiving channel 535 and the discharge channel to squeeze the spring so that the spring is assembled to the base of the second installation position 56. According to the above structural arrangement, the spring falls from the feeding channel of the feeding block 531 into the receiving channel of the receiving block 532. When the receiving block 532 moves from the receiving position to the loading position, the spring is transported to the discharging channel 534 connected to the receiving channel 535. At this time, the spring is in a state to be assembled. The spring is assembled to the base by driving the push rod 536 to penetrate into the discharging channel 534, thereby realizing orderly material distribution, conveying and assembly of the spring, ensuring the timeliness and reliability of assembly between the spring and the base.
