Description

Technical Field

[0001] This invention relates to the field of assembly technology for resilient switch assemblies, and in particular to an automatic assembly machine and method for resilient switch assemblies. Background Technology

[0002] Currently, the flexible switch assembly consists of a body, a switching plate, a flexible element, and a switch. The flexible element has reverse mounting rods at both ends. Because the flexible switch assembly is small, the corresponding switching plate, flexible element, and switch are even smaller than the body. Therefore, extra care is required during manual assembly, resulting in greater assembly difficulty, lower assembly efficiency, and higher labor costs. In particular, when assembling the flexible element, it is necessary to align it with the position limiting structure. Furthermore, because the flexible element is elastic, it is prone to loosening and deviating from the preset swing position, which can lead to switch assembly failure.

[0003] Therefore, the existing technologies mentioned above have the following main shortcomings: there is currently a lack of automated equipment for the automated assembly of flexible switch components, and manual assembly is difficult, inefficient, and costly. Summary of the Invention

[0038] like Figure 1The diagram shows the structure of an elastic switch assembly according to an embodiment of the present invention. The elastic switch assembly consists of a body 1, a switching piece 2, an elastic element 3, and a switch element 4. The elastic element 3 has an irregular structure, specifically, both ends of the elastic element 3 have opposing mounting rods, specifically a lower mounting rod 5 at one end and an upper mounting rod 6 at the other end. The body 1 of this embodiment has a first limiting structure 7 for limiting the switching piece 2, a second limiting structure 8 for limiting the elastic element, and a third limiting structure 9 for limiting the switch element 4. Specifically, the first limiting structure 7 consists of a positioning post and a positioning hole erected on the body 1, and the switching piece 2 has a corresponding positioning sleeve hole and positioning protrusion that cooperate with the positioning post 44. The second limiting structure 8 consists of holes provided on the body 1 and holes on the switching piece 2. The third limiting structure 9 consists of the aforementioned positioning post on the body 1, the upper mounting rod 6 of the elastic element 3, and the first and second locking holes of the switch element 4.

[0039] like Figure 2-3 As shown, this embodiment of the invention provides an automatic assembly machine for a flexible switch assembly, including a main body feeding device 10, a main body transfer device 11, a first support platform 12, a main body positioning device 13, a switching piece assembly device 14, a switching piece feeding device 15, a platform to be transferred 16, a second support platform 17, a flexible element limiting device 18, a flexible element feeding device 19, a flexible element assembly device 20, a flexible element positioning device 21, a switch sub-assembly device 22, a switch sub-feeding device 23, a material collection bin, and a material unloading device 25.

[0040] In order to automate the feeding and transfer of the body 1, the body feeding device 10 in this embodiment uses a combination of vibratory feeder and linear vibration to output the body 1 one by one. Furthermore, under the action of the first body transfer component 27 of the body feeding device 10, the body 1 output from the body feeding device 10 is received one by one and directly transferred to the inlet docking point 26 of the first support platform 12. Then, under the action of the second body transfer component 28, the body 1 located on the first body transfer component 27 is directly pushed from the aforementioned inlet docking point 26 into the first support platform 12. At this time, the body 1 in the first support platform 12 is located at the first assembly station 34. In order to ensure that the body 1 can be in a positioning state when it is assembled in the first assembly station 34, a body positioning device 13 is provided. The body positioning device 13 is located on the side of the first support platform 12. The body positioning device 13 has a second driver and a second positioning block 29. The second driver is used to control the extension and retraction of the second positioning block 29 to achieve positioning of the body 1 located in the first assembly station 34 before the assembly switching piece 2, which greatly improves the accuracy of assembly and improves the assembly efficiency. The first body transfer assembly 27 includes a cylinder and a slide 31. The slide 31 has through holes on both sides for direct vibration connection. These through holes have a contoured structure to prevent significant displacement of the body 1 within the slide 31. The second body transfer assembly 28 includes a cylinder and a push rod. The cylinder controls the push rod to insert into the through hole of the slide 31 from one side and push the body 1 within the through hole to the inlet docking point 26 of the first support platform 12.

[0041] As shown in the figure, in order to provide a smooth transfer process for the main body 1, the first support platform 12 in this embodiment has a first slide 32 and a second slide 33. The first slide 32 and the second slide 33 are perpendicular to each other, and their intersection is the first assembly station 34. A third main body transfer component 35 is provided on the outer side of one end of the first slide 32, and the other end of the first slide 32 serves as the platform to be transferred 16. One end of the second slide 33 is the aforementioned entrance docking point 26, which docks with the aforementioned second main body transfer component 28. The other end of the second slide 33 is provided on the outer side of the aforementioned main body positioning device 13 to limit the position of the main body 1. The third main body transfer component 35 includes a cylinder and a push rod. The cylinder controls the push rod to push the released main body 1 (with the switching piece 2 assembled) along the first slide 32 from the first assembly station 34 towards the transfer station 41. The transfer platform 16 is used to temporarily store several bodies 1 of the assembled switching piece 2, and the first positioning device 36 delivers the bodies 1 of the assembled switching piece 2 to the transfer position 41 on the transfer platform 16 one by one. When the third body transfer component 35 pushes the body 1 from the first assembly station 34 to the first position 37, the first positioning device 36 pushes the body 1 located at the first position 37 to the second position 38 through the first push arm 39. Then, while the first push arm 39 pushes the body 1 located at the first position 37 to the second position 38 again, the second push arm 40 pushes the body 1 located at the second position 38 to the transfer position 41. Of course, a third position, a fourth position and corresponding third push arm, fourth push arm, etc. can be added as needed to temporarily store more bodies 1 of the assembled switching piece 2 to match the time of assembling the elastic component 3 and the switch 4, so as to make the automation smoother.

[0042] As shown in the figure, in order to realize the automated feeding and assembly of the switching piece 2, this embodiment uses the switching piece feeding device 15 to realize the one-by-one feeding of the switching piece 2, specifically by using a vibratory plate and a direct vibration. Then, the vacuum adsorption material handling robot of the switching piece assembly device 14 sends the switching piece 2 one by one from the direct vibration outlet to the first assembly station 34 and places the switching piece 2 on the body 1 at a preset position. During the process of placing it down, the positioning hole of the switching piece 2 is aligned with the positioning post on the surface of the body 1, that is, aligned by the first limiting structure 7 to complete the assembly. After the assembly is completed, the switching piece 2 assembly device 14 is reset.

[0043] After the assembly of the switching piece 2 and the main body 1 is completed, the main body 1, together with the switching piece 2, needs to be transferred to the second assembly station 43 to continue the assembly of the elastic element 3 and the switch element 4. Therefore, in this embodiment, the main body transfer device 11 is used to transfer the main body 1 together with the switching piece 2 by clamping and picking up the material. The main body transfer device 11 is located on the side of the first support platform 12.

[0044] To provide a second support platform 17 for supporting and positioning the main body 1, the second support platform 17 in this embodiment has a third slide rail 42. The middle section of the third slide rail 42 is a second assembly station 43. One end of the third slide rail 42 is provided with a material collection bin for collecting the elastic switch assembly, and the other end is provided with a material unloading device 25. The material unloading device 25 is used to push the assembled elastic switch assembly from the second assembly station 43 along the third slide rail 42 to the material collection bin. The second assembly station 43 on the second support platform 17 is provided with a liftable positioning column 44. The positioning column 44 is driven and controlled by a cylinder to position the main body 1 after lifting and to release the positioning of the main body 1 after lowering, so that the main body 1 can be unloaded under the action of the material unloading device 25. In this embodiment, the second support platform 17 is located beside the first support platform 12.

[0045] To automate the feeding and limiting transfer of the elastic element 3, the elastic element feeding device 19 of this embodiment uses a vibratory feeder and a linear vibrator to dispense the material one by one. A lifting device 45 is provided at the outlet of the linear vibrator to lift each individual elastic element 3 to a plane that aligns with the limiting platform 47, facilitating subsequent movement of the elastic element 3 on the limiting platform 47. The elastic element limiting device 18 of this embodiment can limit each elastic element 3 to a preset orientation, and then, in conjunction with the elastic element assembly device 20, transfer it to the second assembly station 43 while maintaining this limiting state. The elastic element limiting device 18 of this embodiment includes a pushing component 46 and a limiting platform 47. The limiting platform 47 is provided with a guide groove 48 and an elastic limiting block 49. The pushing component 46 is used to limit the elastic element 3 in a preset swing direction in the elastic limiting block 49 under the guidance of the guide groove 48. The elastic limiting block 49 is used to limit the elastic element 3 within it to maintain the preset swing direction. When the lower mounting rod 5 of the elastic element 3 enters the guide groove 48, the elastic element 3 gradually adjusts its swing direction until it enters the limiting range of the elastic limiting block 49 and completes the adjustment to the preset swing direction limiting state. Since the elastic limiting block 49 can elastically rise and fall on the limiting platform 47, when the elastic assembly device picks up the material, the downward pressure on the elastic limiting block 49 causes the elastic limiting block 49 to descend, so as to gradually expose the limited elastic element 3. At the same time as it is exposed, the elastic assembly device takes over to continue to maintain the limiting position. The specific elastic assembly device includes a first moving drive assembly, a limiting pick-up head 50, and a vacuum adsorption device. The limiting pick-up head 50 and the vacuum adsorption device are assembled on the first moving drive assembly. The picking surface of the limiting pick-up head 50 has a limiting groove 24 for maintaining the limiting state of the elastic element 3. The vacuum adsorption device is used to adsorb the elastic element 3, which is limited in the limiting groove 24, through the limiting groove 24 during assembly and transfer. During picking, the picking surface presses down the elastic limiting block 49, and transfers the limited elastic element 3 to the limiting groove 24 while maintaining the limiting state. At the same time, the elastic element 3 is adsorbed by vacuum adsorption to ensure the reliability of the transfer. The limiting groove 24 has an arc surface that matches the shape of the elastic element 3, as well as a hole for inserting the upper mounting rod into the limiting groove, so that the elastic element 3 can fill the limiting groove 24 to ensure the adsorption effect of the elastic element 3.

[0046] Since the elastic element 3 is prone to loosening and changing its limiting state after being assembled on the switching plate 2, it is necessary to position the elastic element 3 by setting an elastic element positioning device 21. This device is located beside the second support platform 17 and has a first driver and a first positioning block 30. The first driver controls the first positioning block 30 to enter the second support platform 17 and move to the surface of the elastic element 3 for post-assembly positioning. In another embodiment, the first positioning block 30 can be added according to the shape of the elastic element 3 and the required positioning position to achieve better positioning of the elastic element 3. The lower mounting rod 5 of the elastic element 3 is assembled by aligning the holes on the body 1 and the switching plate 2 using the second limiting structure 8. Then, the position of the elastic element 3 is fixed using the aforementioned elastic element positioning device 21 before assembling the switch 4. Alternatively, the switching plate positioning device can be used to position the switching plate 2 before assembling the elastic element 3, ensuring that the holes on the switching plate 2 are aligned with the lower mounting rod 5 of the elastic element 3.

[0047] To achieve automated feeding and assembly of the switch element 4, this embodiment uses a switch element feeding device 23, which uses a vibratory feeder and direct vibration to individually feed the switch elements 4. The switch element assembly device 22 then transfers each switch element 4 to the second assembly station 43. The switch element 4 is assembled onto the surface of the body 1 via a third limiting structure 9 integrated between the body 1, the elastic element 3, and the switch element 4. Specifically, the first locking hole of the switch element 4 fits onto the positioning post 44 of the body 1, and the second locking hole fits onto the upper mounting rod 6 of the elastic element 3. The switch element assembly device 22 uses a clamp or retractable locking block to fix the switch element 4 during feeding, and then transfers it to the second assembly station 43. After the preset transfer stroke is completed, the device descends to directly align and assemble the switch element with the body and the elastic element.

[0048] The automatic assembly method for the resilient switch assembly provided in this embodiment includes the following assembly steps:

[0049] Step S1: The main body 1 is fed one by one by the main body feeding device 10 and transferred one by one to the first assembly station 34 of the first support platform 12.

[0050] Step S2: The switching piece 2 is fed one by one by the switching piece feeding device 15 and transferred one by one to the first assembly station 34 by the switching piece assembly device 14. The switching piece 2 is limited on the body 1 by the first limiting structure 7 between the body 1 and the switching piece 2, so as to complete the assembly of the switching piece 2 and the body 1.

[0051] Step S3: The main body 1 connecting switching piece 2 located on the first assembly station 34 is transferred to the second assembly station 43 of the second support platform 17 by the main body transfer device 11.

[0052] Step S4: The elastic component 3 is fed one by one by the elastic component feeding device 19, and the elastic component 3 is limited one by one in a preset swing direction by the elastic component limiting device 18. The elastic component 3 is transferred to the switching plate 2 on the second assembly station 43 by the elastic component assembly device 20 while maintaining the limited state of the elastic component 3. The elastic component 3 is limited on the switching plate 2 by the second limiting structure 8 between the elastic component 3 and the body 1, so as to complete the assembly of the elastic component 3, the switching plate 2, and the body 1.

[0053] In step S5, the switch 4 is fed one by one by the switch feeding device 23, and the switch 4 is transferred one by one to the second assembly station 43 by the switch assembly device 22. The switch 4 is then limited on the body 1 by the third limiting structure 9 between the switch 4, the elastic element 3 and the body 1, so as to complete the assembly of the switch 4 with the elastic element 3, the switching piece 2 and the body 1.

[0054] The working principle of this invention embodiment is as follows: The purpose of the assembly method described above is to provide fully automated assembly of the flexible switch assembly, thereby solving the problems of low assembly efficiency and high labor costs caused by manual assembly in the prior art.
