DETAILED DESCRIPTION

[0024] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0025] Depend on Figure 1 Combination Figure 2-8As shown, an assembly device for a contact assembly includes a mounting frame 1, on which a turntable 2, a driving element 3 for driving the turntable 2 to rotate circumferentially, and a plurality of processing devices 4 arranged around the turntable 2 are provided. The turntable 2 is provided with a plurality of fixture assemblies 5, each of which corresponds to a set of fixture assemblies 5. Each set of processing devices 4 includes a material ejection mechanism 6 for clamping a spring frame 91 into a contact blade 92 for fixing, a punching mechanism 7 for hole processing on the spring frame 91, and a material taking mechanism 8 for taking materials out of the fixture assembly 5. The fixture assembly 5 is provided with fixtures 51 at the material ejection mechanism 6, the punching mechanism 7, and the material taking mechanism 8. The material ejection mechanism 6, the punching mechanism 7, and the material taking mechanism 8 are sequentially arranged on the turntable 2. The beneficial effect of the present invention is that a fixture and a processing device are provided, and the product can be processed quickly and reliably through the processing device, especially when the contact blade and the elastic member are fixed, the spring frame can be quickly clamped into the limit position, and the hole can be punched quickly and reliably, so that the contact assembly is easy to assemble, the processing efficiency is high, and time and labor are saved. The present invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life. Specifically, the present invention is to place the contact blade 92 and the spring piece 93 on the fixture corresponding to the ejection mechanism at the first station, that is, the ejection station, and limit the contact blade through the slot of the positioning plate, and set the spring frame at the end of the limit seat near the contact blade. Since the two slots are arranged in a "mountain" shape and the positioning part is arranged in a truncated cone shape, the spring frame can be arranged at a smaller opening of the contact blade, which is convenient for the ejection mechanism to push the spring frame, so that the spring frame can be reliably assembled. In addition, the present invention can process multiple groups of processing devices at the same time to improve production efficiency. The driving element 3 is connected to the turntable 2 through the cantilever beam 31 and drives the turntable 2 to rotate. The processing device 4 has at least three groups, and the processing device 4 is evenly distributed on the mounting frame 1 in the circumferential direction. In the drawings of the present invention, there are three groups of processing devices, which makes the product volume appropriate, each station will not affect each other, and is convenient for collecting materials, and the processing efficiency is high. This is the preferred mode of the present invention. Of course, in the actual production and processing process, two, four, five, six or more groups of processing devices can also be set.

[0026] The ejection mechanism 6 includes an ejection plate 61 and an ejection driving member 62 for driving the ejection plate 61 to move horizontally. The ejection plate 61 is provided with a shoulder portion 611 for pushing the spring frame 91. Specifically, the ejection plate 61 is provided with a notch groove 612 and a groove 613. The ejection plate 61 cooperates with the fixture 51 at the notch groove 612 to form an accommodating space 614 for accommodating the contact blade 92. The ejection plate 61 is placed above the contact blade 92 at the groove 613 to vertically limit the contact blade 92. The notch groove is provided to horizontally limit the contact blade, the shoulder portion can reliably push the spring frame to move horizontally, the ejection plate and the positioning plate on the fixture cooperate to guide the movement of the ejection plate, and the groove is provided to vertically limit the contact blade. The ejection mechanism makes the ejection plate reliable and facilitates the rapid assembly of the spring frame.

[0027] The punching mechanism 7 includes a limiting assembly 71 and a punching assembly 72. The limiting assembly 71 includes a limiting plate 711 that cooperates with the clamp 51 to limit the contact blade 92 and a limiting driving member 712 that drives the limiting plate 711 to move horizontally. The punching assembly 72 includes a punching frame 721. The punching frame 721 is provided with a punching driving member 722. The punching driving member 722 is provided with a punch 723 for processing the hole to be processed on the spring frame 91. Specifically, the clamp 51 is provided with a punching needle 511. When the punching driving member 722 is in motion, the punching needle 511 cooperates with the punch 723 to process the hole on the spring frame 91. The spring frame is provided with a bending plate 911. When the spring frame is installed, in order to avoid interference and to be flush with its outer surface, the bending plate 911 needs to be bent to form a clamping hole 912 after the spring frame is inserted, so as to horizontally limit the contact blade 92 and the spring piece 93. The punching drive can drive the punch to bend the bending plate on the upper surface of the spring frame, and the limit column can press the clamp, so that the punch needle extends out of the limit seat of the clamp to bend the lower surface of the spring frame, thereby forming a clamping hole. This makes the product processing convenient and reliable.

[0028] The punching frame 721 is provided with a pressing plate 724, and the pressing plate 724 is provided with a limiting column 725. The punching needle 511 has a first state in which it is retracted into the fixture 51 and a second state in which the fixture is driven by the limiting column 725 to extend out of the fixture 51 and cooperate with the punch 723 to perform hole processing on the spring frame 91. The setting of the limiting component limits the contact assembly, which is convenient for reliable hole processing of the contact assembly, and the processing is convenient and reliable. In particular, the limiting plate and the material taking frame can adopt a structure similar to the ejecting plate at the position where the contact assembly is limited, such as also providing a notch groove, a groove, a shoulder portion, etc., which can further prevent the spring frame from shifting, and make the product limit reliable, which is convenient for subsequent punching or material taking.

[0029] The material taking mechanism 8 comprises a horizontal driving member 81 and a vertical driving member 82 for inserting into the hole of the spring frame 91 for the contact blade 92 to take the material. The horizontal driving member 81 is provided with a material taking frame 83, and the vertical driving member 82 is provided on the material taking frame 83. The horizontal driving member 81 drives the vertical driving member 82 to move horizontally through the material taking frame 83. The mounting frame 1 is provided with a receiving hole 11 for receiving the processed material at the material taking mechanism 8. Such a structure makes it convenient to take the product material, that is, the manual operation only needs to control the material discharge, and the processing can be completed after the material discharge is completed. The product assembly is convenient and reliable, and the production efficiency is high.

[0030] The clamp 51 includes a base 512, a limiting seat 513 and a positioning plate 514 for positioning the contact blade 92. The positioning plate 514 is fixed on the limiting seat 513. The limiting seat 513 and the base 512 slide upward and downward. Specifically, a gap 515 is provided between the limiting seat 513 and the base 512. An elastic member 516 is provided in the gap 515. Two slots 5141 are provided on the positioning plate 514. A positioning portion 5142 for inserting into the spring frame 91 is provided between the two slots 5141. An inclined surface 5131 is provided on the side of the limiting seat 513 close to the positioning plate 514. The limiting seat and the positioning plate can float up and down relative to the base, so as to facilitate reliable bending hole processing on the upper and lower surfaces of the spring frame.
