Fig. 8 is a schematic view of the spring mounting portion 122, fig. 9 is a schematic view of the first sheet punching portion 167 and the third manipulator portion 168 in fig. 8, with reference to fig. 8 and 9 and with additional reference to fig. 1, in some embodiments, in order to enable high-speed and continuous feeding of the spring 103, the spring mounting portion 122 includes: a first sheet feeding section 166, a first sheet punching section 167, and a third hand section 168. The first sheet feeding unit 166 is provided to continuously feed one end of the first sheet 169 in a roll shape. The first sheet punching section 167 is provided to punch one end of the first sheet 169 continuously fed out to form the elastic sheet 103. The third manipulator section 168 is configured to take the spring plate 103 from the first sheet punching section 167 and assemble the spring plate 103 to the jig 119 when one of the jigs 119 is located at a loading position (also referred to herein as a spring plate loading position 176) of the third manipulator section 168.

The first sheet feeding unit 166 is attached to the base 117 by a bracket such as an aluminum material. The first sheet feeding section 66 includes a first motor 170 and a second motor 171. Wherein, the first motor 170 is connected to the first supporting roller 172 and drives the first supporting roller 172 to rotate. The first sheet 169 in a roll shape is supported by the first support roller 172, and the first sheet 169 is continuously fed out as the first support roller 172 is driven by the first motor 170. The second motor 171 is connected to the second support roller 173 and drives the second support roller 173 to rotate. First protective paper (not shown) for protecting the first sheet 169 peeled from the rolled first sheet 169 is wound around the second support roller 173, and the first protective paper is collected while being wound as the second support roller 173 is driven by the second motor 171.

The first sheet 169 fed out from the first sheet feeding section 166 is fed to the first sheet punching section 167. The first sheet punching portion 167 is provided on the base 117. The first sheet punching section 167 includes, for example, a plurality of first punching cylinders 174, and a plurality of first punches 175 are mounted on the first punching cylinders 174. The number and specifications (output force) of the first punching cylinders 174 are determined according to the position and number of the striking plate 103 to be punched, and the like, and are not particularly limited herein. Similarly, the shape of the first punch 175 is determined according to the actual shape of the spring plate 103, and is not particularly limited herein.
