Description

Technical Field

[0001] This utility model relates to an assembly device for a micro switch, and more specifically, to a fixed terminal assembly mechanism for a micro switch. Background Technology

[0002] Figures 1 to 3 The diagram shows a commonly used micro switch 100, which mainly consists of a lower housing 101, a fixed terminal 102, a contact terminal 103, a push button 104, and an upper housing 105. The fixed terminal 102 and the contact terminal 103 are fixedly mounted on the lower housing 101. The contact terminal 103 has a spring arm and is generally L-shaped. The push button 104 is mounted on the upper housing 105 and together with it on the lower housing 101, with the inner end of the push button 104 abutting against the spring arm of the contact terminal 103. In use, pressing down the push button 104 causes the free end of the spring arm to contact the fixed terminal 102, thus establishing a connection between the fixed terminal 102 and the contact terminal 103. Releasing the push button 104 resets the switch under the elastic action of the spring arm. This micro switch 100 has a simple structure and is widely used in various electronic and mechanical equipment, with a very large demand.

[0003] To improve the production efficiency and product quality stability of micro switches, automated equipment is now widely used to replace manual assembly. For example, the "Automatic Assembly and Testing Machine for Micro Switches" disclosed in Chinese Patent Publication No. CN107695676A (publication date: February 16, 2018) demonstrates this. Although different automated assembly equipment targets different micro switch structures, the assembly process is largely the same. Most utilize multi-station rotary tables for assembly, including feeding, assembly, testing, and unloading mechanisms arranged around the rotary table. The multi-station rotary table drives the various components to move between different stations, achieving automated feeding, assembly, testing, and unloading, greatly improving the production efficiency and product assembly consistency of micro switches.

[0004] However, since the aforementioned fixed terminal 102 is a straight metal sheet with small size and thin thickness, it increases the difficulty of gripping and feeding the terminal during the assembly process. Furthermore, based on the upper and lower assembly structure of the aforementioned micro switch 100, the fixed terminal 102 needs to be gripped and pressed in a vertical position, and the existing spiral feeder and vertical vibratory feeder are difficult to achieve the vertical conveying of the aforementioned fixed terminal 102. Chinese Patent Publication No. CN115083813A discloses "An Automatic Assembly Machine for Micro Switch Components" (publication date: September 20, 2022). After the terminals (contact pieces) are conveyed horizontally, they are gripped by a clamping cylinder and rotated 90° by a rotary cylinder, so that the contact pieces are arranged horizontally, and then assembled onto the pin seat. Although this method can change the assembly direction of the contact pieces, the entire gripping mechanism requires many moving joints, which is not conducive to ensuring the alignment accuracy and pressing stability of the contact pieces and pin seats.

[0005] In view of the above-mentioned problems in the existing technology, in order to realize the automated assembly of the micro switch 100, it is necessary to develop and design a fixed terminal assembly mechanism for the micro switch. Summary of the Invention

[0038] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0039] [Example]

[0040] Combination Figure 4 and Figure 5 As shown, a fixed terminal assembly mechanism for a micro switch in this embodiment is installed at the fixed terminal assembly station of a multi-station rotary table 1. The multi-station rotary table 1 is an existing product, which has a rotatable turntable 1-1. The turntable 1-1 is driven to rotate by a turntable drive mechanism. Several clamping assemblies 1-2 are provided on the turntable 1-1 at equal angles in the circumferential direction. Figure 4 The diagram shows a six-station rotary table, therefore, six sets of fixture assemblies 1-2 are evenly distributed around the turntable 1-1, with each set of fixture assemblies 1-2 corresponding to an assembly station. The fixed terminal assembly mechanism in this embodiment corresponds to the fixed terminal assembly station of the multi-station rotary table 1. This fixed terminal assembly mechanism for the microswitch includes a reversing mechanism 21 and a pressing mechanism 22. The reversing mechanism 21 is used to convert the fixed terminal 102, which is transported from a horizontal state, to a vertical state. The pressing mechanism 22 is used to grip the vertically positioned fixed terminal 102 and press it into the lower housing 101 to be assembled.

[0041] The reversing mechanism 21 has a reversing block 21-1 that can rotate and switch between horizontal and vertical positions. The reversing block 21-1 is generally rectangular. The reversing block 21-1 also has an ejection assembly 21-2, which is used to push the fixed terminal 102 in the reversing block 21-1 outward to facilitate the pressing mechanism 22 to grasp the fixed terminal 102. A feeding assembly is also provided on one side of the reversing block 21-1 for feeding the fixed terminal 102 into the reversing block 21-1 when it is in a horizontal position, so as to separate the fixed terminal 102 fed in from the horizontal position one by one and feed it into the reversing block 21-1.

[0042] The pressing mechanism 22 includes a gripping block 22-1 mounted on a bidirectional motion assembly. A push pin seat 22-2 is provided above the gripping block 22-1. A push pin 22-2a located inside the gripping block 22-1 is mounted on the push pin seat 22-2. The lower end of the push pin 22-2a is located in the terminal receiving groove of the gripping block 22-1. When gripping the fixed terminal 102, the ejector assembly 21-2 pushes the fixed terminal 102 into the terminal receiving groove of the gripping block 22-1 in a vertical state. The push pin seat 22-2 is connected to the pressing cylinder 22-3 and is used to grip the fixed terminal 102 from the reversing block 21-1 which has been rotated to a vertical position and press it into the lower housing 101 at the fixed terminal assembly station.

[0043] Reference Figure 8 and Figure 9 As shown, in this embodiment, the reversing block 21-1 is provided with a material hole that runs vertically through the material hole. The material hole is used to accommodate the fixed terminal 102. The ejection assembly 21-2 includes an ejector pin 21-2a disposed in the material hole. The ejector pin 21-2a is used to eject the fixed terminal 102 in the material hole upward when the gripping block 22-1 grips the fixed terminal 102. Specifically, the ejection assembly 21-2 further includes a push rod 21-2b and a pin return spring 21-2c. The push rod 21-2b is fixedly connected to the lower end of the pin 21-2a, and its tail extends out of the reversing block 21-1. The pin return spring 21-2c is sleeved on the pin 21-2a, with one end abutting against the reversing block 21-1 and the other end abutting against the push rod 21-2b, to maintain the inward elastic tendency of the pin 21-2a. A push driver, which can be a cylinder, is also provided below the reversing block 21-1 to drive the push rod 21-2b upward. Using this ejection assembly, the fixed terminal 102 can be held in the material hole during the rotation of the reversing block 21-1, and the fixed terminal can be pushed outward using the push driver during the gripping process. The structure is simple and compact, and the ejection action is stable and reliable. Figure 9 The diagram shows the reversing block 21-1 rotated to a horizontal state. At this time, the material hole of the reversing block 21-1 is in a horizontal state, and the ejector pin 21-2a is also in a retracted state. At this time, the feeding assembly can send the horizontal fixed terminal 102 into the material hole of the reversing block 21-1. Figure 8 The diagram shows the reversing block 21-1 rotating to the vertical position. At this time, the fixed terminal 102 also changes to the vertical position. During the gripping process, the push-top driver drives the push-top rod 21-2b to move upward, and pushes the fixed terminal 102 upward through the push pin 21-2a.

[0044] like Figure 5 and Figure 7As shown, in this embodiment, the reversing block 21-1 is mounted on the rotary cylinder 21-3, and the rotary cylinder 21-3 drives the reversing block 21-1 to rotate and switch. One side of the reversing block 21-1 is also provided with an arc-shaped baffle 21-9 arranged along the rotation stroke of the reversing block 21-1. The upper end surface of the reversing block 21-1 is also preferably arc-shaped. The arc-shaped baffle 21-9 can effectively prevent the fixed terminal 102 from being thrown out during the rotation of the reversing block 21-1, and further improve the stability of the fixed terminal 102 when it changes from a horizontal state to a vertical state.

[0045] catch Figure 5 , Figures 7 to 9 As shown, the above-mentioned feeding assembly includes a feeding seat 21-4, a discharge slider 21-5, a discharge cylinder 21-6, a push slider 21-7, and a push cylinder 21-8. The feeding seat 21-4 is located on one side of the reversing block 21-1. The feeding seat 21-4 has a push slide opposite to the horizontally positioned reversing block 21-1. The discharge slider 21-5 is perpendicular to the push slide and is located on the feeding seat 21-4. The discharge cylinder 21-6 is connected to the discharge slider 21-5 and is used to drive the feeding groove on the discharge slider 21-5 to switch between the receiving position and the feeding position. The receiving position of the feeding seat 21-4 is connected to the direct vibration feeder of the fixed terminal 102. The discharge slider 21-5 can be used to move the fixed terminal 102 from the receiving position to the feeding position. The push slider 21-7 is mounted on the feeding seat 21-4 along the push slide direction. The push cylinder 21-8 is connected to the push slider 21-7 and is used to push the fixed terminal 102 in the feeding slot of the discharge slider 21-5 into the material hole of the horizontally positioned reversing block 21-1 via the push slide. The above-mentioned feeding assembly has a simple and compact structure, and the feeding action is smooth and efficient, improving the accuracy and stability of fixed terminal feeding.

[0046] like Figures 4 to 6 As shown, in this embodiment, the aforementioned bidirectional motion assembly includes a longitudinal slide 22-4, a longitudinal cylinder 22-5, a transverse slide 22-6, a fixed frame 22-7, and a transverse cylinder 22-8. The gripping block 22-1 and the pressing cylinder 22-3 are respectively mounted on the longitudinal slide 22-4. The push pin seat 22-2 is slidably mounted on the longitudinal slide 22-4. The longitudinal slide 22-4 is mounted on the drive end of the longitudinal cylinder 22-5, which drives the gripping block 22-1 to move up and down. The longitudinal cylinder 22-5 is mounted on the transverse slide 22-6, which is horizontally slidably mounted on the fixed frame 22-7. The transverse cylinder 22-8 is mounted between the transverse slide 22-6 and the fixed frame 22-7, which drives the gripping block 22-1 to move horizontally. By using the aforementioned bidirectional motion assembly, bidirectional movement control of the gripping block 22-1 in both the horizontal and vertical directions is achieved, which facilitates the gripping and pressing of the fixed terminal 102.

[0047] Reference Figure 4 and Figure 5 As shown in the figure, the operation process of the fixed terminal assembly mechanism of the micro switch in this embodiment is as follows:

[0048] Fixed terminals 102 are sequentially conveyed to the receiving position of the feeding seat 21-4 via a spiral feeding disc and a vertical vibrating feeder. The foremost fixed terminal 102 enters the discharge slider 21-5 in a horizontal state and is moved to the feeding position by the discharge cylinder 21-6. Then, the push cylinder 21-8 moves the push slider 21-7 forward, feeding the fixed terminal 102 on the discharge slider 21-5 into the material hole of the horizontal reversing block 21-1 via the push slide. Afterward, the rotary cylinder 21-3 rotates the reversing block 21-1 to a vertical position, and the longitudinal movement cylinder 22-5 moves the gripping block 22-1 downward to the reversing block 21-4. Above -1, the terminal receiving groove of the gripping block 22-1 is aligned with the material hole of the reversing block 21-1; the push drive drives the push rod 21-2b to move upward, and the ejector pin 21-2a pushes the fixed terminal 102 upward into the terminal receiving groove; then, under the action of the longitudinal cylinder 22-5 and the transverse cylinder 22-8, the gripping block 22-1 is moved to the fixed terminal assembly station, so that the terminal receiving groove is aligned with the terminal insertion hole of the lower housing 101. Then the pressing cylinder 22-3 is activated, which drives the push pin 22-2a to press the fixed terminal 102 in the terminal receiving groove into the terminal insertion hole of the lower housing 101, thus completing the assembly of the fixed terminal 102.

[0049] This utility model discloses a fixed terminal assembly mechanism for a micro switch, which can stably switch the fixed terminal from a horizontal state to a vertical state for gripping and assembly. With the design of ejecting, gripping and pressing the fixed terminal, it solves the problem of difficult gripping and assembling of thin metal terminals, and has the advantages of simple structure, good action stability and high assembly efficiency.

This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
