[0029] Example 1, see Figures 1 to 6 The utility model provides a T-arm switch fixture, which comprises a pressing plate 1 and a base plate 2 arranged in parallel. Figure 1As the viewing angle, the pressing plate 1 is above the substrate 2. The substrate 2 is connected with a plurality of first clamping arms 3 penetrating the pressing plate 1, and the first clamping arms 3 are stationary relative to the substrate 2. The pressing plate 1 is connected with a second clamping arm 4 corresponding to the first clamping arm 3. The correspondence here means that the second clamping arm 4 is located directly below the first clamping arm 3, and the first clamping arm 3 and the second clamping arm 4 are provided with a plurality of clamping points 5 one-to-one vertically up and down, and the plurality of groups of vertically corresponding clamping points 5 are suitable for clamping the sheet 100, which can be but not limited to a circuit board, a silicon wafer, a solar cell, etc. An elastic member 6 is provided between the first clamping arm 3 and the pressing plate 1, and the second clamping arm 4 is suitable for being driven by the pressing plate 1 to move away from or approach the first clamping arm 3 when the elastic member 6 is compressed or restored, so that the plurality of clamping points 5 can release or clamp the sheet 100. That is, since the first clamp arm 3 is stationary relative to the base plate 2, and an elastic member 6 is provided between the first clamp arm 3 and the pressing plate 1, the elastic member 6 is arranged so that in the initial state, the multiple clamping points 5 on the first clamp arm 3 and the second clamp arm 4 can just clamp the sheet 100. Once an external force is applied, the external force pushes the pressing plate 1 downward, so that the pressing plate 1 also drives the second clamp arm 4 downward, and then the clamping point 5 of the second clamp arm 4 is away from the clamping point 5 of the first clamp arm 3, so as to release the sheet 100 or feed the sheet 100. Once the external force is lost and the pressing plate 1 is no longer pushed downward, the elastic member 6 begins to return to the initial state under its own elastic force, and at this time the elastic member 6 drives the pressing plate 1 and the second clamp arm 4 connected to the pressing plate 1 upward, so that the multiple supporting points 5 of the second clamp arm 4 begin to clamp the sheet 100 with the multiple clamping points 5 of the first clamp arm 13. In order to enable electroplating after the sheet 100 is clamped, the pressing plate 1, the substrate 2, the first clamping arm 3, the second clamping arm 4, and the clamping point 5 are all made of conductive metal materials, and conductive plates 11 are connected to both ends of one side of the pressing plate 1, and the external power supply is connected through the conductive plate 11. The pressing plate 1, the substrate 2, the first clamping arm 3, the second clamping arm 4, and the clamping point 5 are all coated with a non-conductive coating, and only the contact point where the clamping point 5 contacts the sheet 100 is exposed and energized.
[0030] See Figure 1 , Figure 2 , Figure 3 In this embodiment, the first clamp arm 3 and the second clamp arm 4 are T-shaped arms. The T-shaped head of the T-shaped arm is convenient for connection and fixation, and the straight tail of the T-shaped arm cooperates with the clamping point 5 for clamping. In order to facilitate clamping the sheet 100, there are at least four first clamp arms 3, and eight in this embodiment. The four first clamp arms 3 are arranged in a rectangle, and every two are arranged facing each other to cooperate with the corresponding second clamp arms 4 to clamp the sheet 100. Of course, it can be understood that according to the production capacity and design requirements, the first clamp arms 3 can be 4*N, and N is greater than or equal to 1.
[0031] In this embodiment, in order to match the T-shaped head of the T-shaped arm, the elastic member 6 is a strip-shaped spring pressing sheet, and the two sides of the T-shaped head of each T-shaped arm are connected by two elastic members 6. That is, the adjacent two ends of the two elastic members 6 are respectively connected to the two sides of the T-shaped head of the first clamping arm 3, and the other two ends of the two elastic members 6 are respectively connected to the pressing plate 1.
[0032] Example 2, see Figures 1 to 6 The difference between this embodiment and the first embodiment is that in order to allow the second clamp arm 4 to move away from or approach the first clamp arm 3, a guide column 7 is connected to the first clamp arm 3. The connection here can be a bolt connection between the first clamp arm 3 and the guide column 7, so as to facilitate disassembly and maintenance; it can also be other connection methods such as welding and riveting, which are not absolutely limited here. The guide column 7 penetrates the second clamp arm 4 and the pressure plate 1, and the second clamp arm 4 and the pressure plate 1 are slidably connected to the guide column 7. The second clamp arm 4 and the pressure plate 1 move away from or approach the first clamp arm 3 by sliding on the guide column 7.
[0033] In this embodiment, the base plate 2 is provided with a base protrusion 8, and the guide column 7 is fixedly connected to the base protrusion 8. The base protrusion 8 can reduce the height of the guide column 7 as much as possible while ensuring that sufficient vertical displacement space is reserved for the second clamping arm 4 and the pressure plate 1, thereby saving manufacturing costs. The base protrusion 8 can be connected to the guide column 7 by, but not limited to, practical welding, bolt connection, and the like.
[0034] In this embodiment, bridge plates 9 are connected to both ends of the base plate 2, and the bridge plates 9 are rotatably connected with a plurality of limit nuts 10, which abut against the pressing plate 1. The limit nuts 10 can be rotated manually or placed in a production line for automatic rotation by mechanical contact.
[0035] When in use, the limit nut 10 is turned downward to push the pressing plate 1 downward along the guide column 7, so that the pressing plate 1 also drives the second clamping arm 4 downward, and then the clamping point 5 of the second clamping arm 4 is away from the clamping point 5 of the first clamping arm 3, so as to loosen the sheet 100 or feed the sheet 100. The limit nut 10 is turned upward to no longer push the pressing plate 1 downward, and the elastic member 6 begins to return to the initial state under its own elastic force. At this time, the elastic member 6 drives the pressing plate 1 upward along the guide column 7. At this time, the second clamping arm 4 connected to the pressing plate 1 also moves upward along the guide column 7, so that the multiple support points 5 of the second clamping arm 4 begin to clamp the sheet 100 with the multiple clamping points 5 of the first clamping arm 13.
[0036] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
