Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric contacts, in particular to a silver-point riveting mechanism for thin electric contacts. Background Art
[0002] Thin electrical contacts, as a precision-designed electrical component, play a key role in fields that require high-precision control and stable electrical connections. Contacts, as a vital component of electronic appliances, are responsible for achieving reliable separation and contact when the equipment is turned on and off. However, since metal conductors generate instantaneous heat and sparks when in contact, these phenomena can cause oxidation and electrolysis of the contact points during frequent operations, thus affecting their performance.
[0003] In order to solve these problems, the commonly used method is to enlarge and thicken the contact points, or to use polymer metal materials such as copper and silver for manufacturing. Among them, silver points are the preferred material due to their excellent conductivity, stability and wear resistance. In order to ensure that the silver points can achieve large-area contact with the electrical contacts, improve the current transmission efficiency, and reduce energy loss, the silver points are usually riveted and fixed on the electrical contacts.
[0004] However, there are a series of challenges in the process of riveting and fixing silver dots. First, during the silver dot filling process, the filling may be missing due to equipment misalignment or intermittent feeding, which not only affects the efficiency of riveting and forming, but may also have a negative impact on the overall performance of the equipment. Secondly, a few silver dots have a high hardness during the preparation process and are not easy to deform during riveting, which causes them to be not firmly fixed on the electrical contacts and easy to fall off. In addition, these silver dots with higher hardness are difficult to identify in subsequent manual inspections, further increasing the uncertainty in the production process. Utility Model Content

DETAILED DESCRIPTION
[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.
[0024] The following describes the silver point riveting mechanism of the thin electrical contact according to the embodiment of the utility model in conjunction with the accompanying drawings.
[0025] like Figure 1-3As shown, the silver point riveting mechanism of the thin electrical contact of the embodiment of the utility model comprises a base 10 , a support plate 20 , a filling assembly 30 , a riveting assembly 40 and a pasting assembly 50 .
[0026] There are multiple groups of support plates 20 , and the multiple groups of support plates 20 are respectively arranged on the base 10 , and the filling assembly 30 is arranged on the base 10 .
[0027] It should be noted that the support plates 20 are distributed at intervals on the base 10, and a gap is left between the support plates 20 and the base 10. During transportation, the thin electrical contacts 60 move from the top of the support plates 20 and pass through the filling assembly 30, the riveting assembly 40 and the pasting assembly 50 in sequence during the movement.
[0028] The riveting assembly 40 is disposed on the base 10 , and includes a fixing plate 401 , a first driving component 402 , a connecting frame 403 and a pressing plate 404 .
[0029] Among them, the fixing plate 401 is set on the base 10, the first driving component 402 is set on the fixing plate 401, one end of the connecting frame 403 is set at the output end of the first driving component 402, the pressing plate 404 is set at the other end of the connecting frame 403, and the pasting component 50 is set on the base 10.
[0030] It should be noted that the first driving component 402 described in this embodiment is a cylinder, which is connected to the control switch and the power supply to drive the connection frame 403 to move up and down, thereby driving the pressing plate 404 to move up and down, and punching the silver dots on the thin electrical contact 60 that moves to the bottom of the pressing plate 404, so that the silver dots are fixed to the thin electrical contact 60 by riveting. After the riveting is completed, the thin electrical contact 60 moves to the bottom of the pasting assembly 50, and the silver dots that are loosened by riveting are pasted out.
[0031] Specifically, the steps of installing silver dots on the thin electrical contact and riveting the silver dots on the thin electrical contact are as follows: the thin electrical contact 60 passes through the base 10 during the transportation process, and is supported by a plurality of support plates 20. The thin electrical contact 60 first passes through the filling component 30, and the filling component 30 fills the silver dots in the vacant positions on the thin electrical contact 60. The thin electrical contact 60 filled with silver dots moves to the bottom of the riveting component 40, and the first driving component 402 is operated. The first driving component 402 drives the pressing plate 404 to move up and down through the connecting frame 403. The pressing plate 404 cooperates with the support plate 20 to rivet and fix the silver dots during the downward pressing process. After the riveting is completed, the thin electrical contact 60 moves to the bottom of the pasting component 50. The pasting component 50 pastes the loose silver dots during the rotation process, thereby taking out the silver dots that are not firmly riveted, which is convenient for subsequent riveting and testing.
[0032] In one embodiment of the present invention, Figure 3 As shown, the filling assembly 30 includes a lower shell 301 , an upper shell 302 and a material chute 303 .
[0033] The lower shell 301 is disposed on the base 10 , the upper shell 302 is disposed on the lower shell 301 , and the material passage trough 303 is opened in the lower shell 301 and the upper shell 302 .
[0034] It should be noted that the lower shell 301 and the upper shell 302 are provided with mutually connected material passing grooves 303, in which silver dots are placed in sequence, and the bottom of the silver dots needs to be provided with chamfered corners, so that when the thin electrical contact 60 passes with the silver dots, the silver dots in the material passing groove 303 will not fall, but will only fall into the cavity of the thin electrical contact 60.
[0035] In one embodiment of the present invention, Figure 3 As shown, the pasting assembly 50 includes an outer cover shell 501, a second driving component 502, a pasting mechanism 503 and a material receiving mechanism 504.
[0036] Among them, the outer cover shell 501 is set on the base 10, the second driving component 502 is set on the outer cover shell 501, the pasting mechanism 503 is rotatably set in the outer cover shell 501, and the pasting mechanism 503 is connected to the output end of the second driving component 502, and the material receiving mechanism 504 is set in the outer cover shell 501.
[0037] It should be noted that the outer cover shell 501 is a hollow shell, the second driving component 502 is a stepping motor, the output end of the stepping motor is connected to the pasting mechanism 503 through a reducer, and the pasting mechanism 503 can be set as two groups. When it is set as two groups, the pasting mechanism 503 is driven to rotate by the second driving component 502 by providing sprockets and chains bonded and connected on the two groups of pasting mechanisms 503. The loose silver dots pasted by the pasting mechanism 503 are intercepted and dropped by the material receiving mechanism 504, so that the silver dots can be collected conveniently.
[0038] In one embodiment of the present invention, Figure 3 As shown, the pasting mechanism 503 includes a fixing seat 5031 , a rotating shaft 5032 and a pasting component 5033 .
[0039] The fixing seat 5031 is disposed on the outer cover shell 501 , the rotating shaft 5032 is rotatably disposed on the fixing seat 5031 , and the sticking component 5033 is disposed on the rotating shaft 5032 .
[0040] It should be noted that a through slot is provided on the bottom wall of the outer cover shell 501 , and the pasting member 5033 extends through the through slot to the bottom of the outer cover shell 501 and contacts the surface of the thin electric contact 60 being transported.
[0041] In one embodiment of the present invention, Figure 3 As shown, the material receiving mechanism 504 includes a material receiving plate 5041 and a material receiving groove 5042 .
[0042] The material receiving plate 5041 is disposed in the outer shell 501, and the material receiving plate 5041 is disposed close to the pasting component 5033. The material receiving groove 5042 is opened in the outer shell 501, and the material receiving groove 5042 and the material receiving plate 5041 are connected.
[0043] It should be noted that the receiving plate 5041 is close to the pasting component 5033. When the pasting component 5033 rotates, the pasted silver dots move through the receiving plate 5041 and fall into the receiving slot 5042 for collection.
[0044] In one embodiment of the present invention, Figure 1 As shown, the top area of the support plate 20 is larger than the bottom area of the pressing plate 404 , and the pressing plate 404 is disposed directly above the support plate 20 .
[0045] It should be noted that when the pressing plate 404 moves downward and the silver points are riveted, the silver points are fixed on the supporting plate 20 to ensure uniform force.
[0046] In one embodiment of the present invention, Figure 3 As shown, the adhesive component 5033 is a soft cotton sleeve, and the surface of the soft cotton sleeve is covered with an adhesive layer.
[0047] It should be noted that the adhesive layer on the surface of the adhesive component 5033 adheres the silver dots, thereby driving the loose silver dots to be removed from the thin electrical contact 60 .
[0048] The operation steps of the silver dot riveting mechanism for thin electric contacts of the present invention are as follows: the thin electric contact 60 passes through the base 10 during the conveying process, and is supported by a plurality of support plates 20. The thin electric contact 60 first passes through the filling assembly 30, and the filling assembly 30 fills the silver dots in the vacant positions on the thin electric contact 60. The silver dots are stored in the material trough 303, and the bottom silver dot is tangent to the thin electric contact 60 being conveyed. When there are holes on the thin electric contact 60 that are not filled with silver dots, the silver dots in the material trough 303 fall into the holes to fill the holes.
[0049] The thin electrical contact 60 filled with silver dots moves to the bottom of the riveting assembly 40, and the first driving component 402 is operated. The first driving component 402 drives the pressing plate 404 to move up and down through the connecting frame 403. During the pressing process of the pressing plate 404, the silver dots are riveted and fixed in place with the support plate 20.
[0050] After the riveting is completed, the thin electric contact 60 moves to the bottom of the pasting assembly 50, and the second driving component 502 is operated. The second driving component 502 drives the rotating shaft 5032 to rotate, thereby driving the pasting component 5033 to paste the loose silver dots during the rotation process, so that the silver dots that are firmly riveted are brought out, and the brought out silver dots are intercepted by the receiving plate 5041 and then fall into the receiving groove 5042 for collection. This is convenient for the subsequent re-riveting of the silver dots and the inspection of the thin electric contact 60.
[0051] In summary, the silver dot riveting mechanism for thin electrical contacts in the embodiment of the utility model fills the vacant holes of silver dots on the thin electrical contacts during transportation, improves the forming quality during riveting, and removes the loose and easily falling silver dots after riveting, which facilitates the subsequent inspection of the thin electrical contacts and effectively improves the forming efficiency.
