Description

Technical Field

[0001] This utility model relates to the technical field of hot pressing equipment for wiring terminals, specifically a wiring terminal forming machine. Background Technology

[0002] A thermoplastic terminal is a device used for electrical connections, also known as a thermoplastic connector or heat shrink connector. They are commonly used to connect wires, cables, or conductors to establish a reliable electrical connection. The working principle of a thermoplastic terminal is to tightly bond the wire to the terminal connection part through thermoplastic technology. This usually involves using a special thermoplastic tool to press the terminal onto the wire. During the thermoplastic process, the conductive material inside the terminal softens, making good contact with the surface of the wire, and forming a strong electrical connection after cooling. However, professional thermoplastic equipment for terminal blocks has the following disadvantages in practical use. First, most existing hot pressing equipment uses a single hot pressing head to achieve the hot pressing process of each terminal, but this method is inefficient. Secondly, the hot pressing head of existing hot pressing equipment has a flat hot pressing surface, but the shape of the wiring terminals varies. In order to ensure the hot pressing effect, the hot pressing time needs to be extended, which further reduces the hot pressing efficiency. Furthermore, some hot pressing equipment that uses multiple hot pressing heads has difficulty adjusting the hot pressing intensity according to the adaptability of the wiring terminals; Therefore, a terminal block forming machine is proposed.

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Example 1

[0018] Please see Figures 1 to 5 The present invention preferably provides a technical solution: a terminal block forming machine, comprising: a base plate 111, a back plate 112 longitudinally fixed on the base plate 111; and a hot pressing operation head assembly and a pressure table 114 respectively disposed on the upper and lower parts of the back plate 112. The hot pressing operation head assembly includes an inverted U-shaped frame 113, a pneumatic lifting mechanism disposed in the middle of the inverted U-shaped frame 113, an assembly block 117 fixed at the output end of the pneumatic lifting mechanism, and a rocker arm pushing mechanism disposed on the assembly block 117. It also includes a mounting plate 124 fixed on the back plate 112, and a plurality of elastic telescopic columns are disposed on the mounting plate 124. The top ends of the plurality of elastic telescopic columns abut against the rocker arm pushing mechanism, and their bottom ends face the pressure table 114 and are provided with hot pressing head structures of different models. When the pneumatic lifting mechanism drives the rocker arm pushing mechanism to run, the hot pressing head structures on the plurality of elastic telescopic columns adaptably clamp the terminal block with the pressure table 114 for hot pressing operation of the terminal block.

[0019] In this embodiment, the inverted U-shaped frame 113, the mounting plate 124, and the pressure-bearing platform 114 are distributed sequentially at the top, middle, and bottom, respectively. Figure 1 , 2 As shown in Figure 3, one end of several elastic telescopic columns on the mounting plate 124 is connected to the pneumatic lifting mechanism, assembly block 117, and rocker arm pushing mechanism on the inverted U-shaped frame 113, while the other end faces the pressure plate 114 and is equipped with a hot press head structure. The specific combination... Figure 1 , 2 As shown in Figure 3, the pneumatic lifting mechanism, assembly block 117, and rocker push mechanism are installed in sequence. The pneumatic lifting mechanism is directly assembled with the inverted U-shaped frame 113 and drives the assembly block 117 to move longitudinally. The rocker push mechanism is installed on the assembly block 117 and directly contacts the tops of several elastic telescopic columns. Therefore, when the lifting mechanism is started, the rocker push mechanism can adaptively squeeze or disengage from several elastic telescopic columns. This process simultaneously realizes the contact or disengagement process between the hot press head structure and the wiring terminal. This application takes into account the wide variety of terminal block models and sizes. To improve the hot pressing quality, when several hot pressing head structures use different models, the terminal blocks can be subjected to targeted hot pressing processes. When several hot pressing head structures operate synchronously, the synchronous hot pressing process of the several hot pressing head structures can be achieved, improving the hot pressing efficiency. At the same time, under the transmission of the rocker arm push mechanism and the adaptive extension and contraction characteristics of several elastic telescopic columns, when several terminal blocks are placed under several hot pressing head structures at the same time, the several hot pressing head structures can adaptively hot press according to the size of several terminal blocks, realizing adaptive adjustment of hot pressing intensity and improving the hot pressing quality.

[0020] Furthermore, the pneumatic lifting mechanism includes a cylinder 116 disposed in the middle of the inverted U-shaped frame 113, wherein an assembly block 117 is assembled at the output end of the cylinder 116, such as... Figure 1 , 2 As shown in Figures 3 and 4.

[0021] Furthermore, a number of slide rail and slide groove assemblies 115 are provided between the back plate 112 and the assembly block 117 for limiting the lifting and lowering of the assembly block 117. Each slide rail and slide groove assembly 115 includes a slide rail fixed on the back plate 112 and a slider slidably mounted on the slide rail. The slider is fixedly connected to the side wall of the assembly block 117. This is an existing mature technology used to improve the movement stability of the assembly block 117. The specific operation will not be described in detail.

[0022] Example 2

[0023] In another embodiment of this utility model, the rocker arm pushing mechanism includes two U-shaped frames 118 fixed to the bottom of the assembly block 117. Each U-shaped frame 118 is rotatably mounted with a first pin 119 at its opposite ends. The two first pins 119 are respectively fixed with a first mounting bracket 120 on their opposite sides and a second mounting bracket 121 on their opposite sides. The two second mounting brackets 121 are staggered and centrally symmetrically distributed. The rocker arm 123 is fixed to the bottom end of the two second mounting brackets 121 and abuts against two adjacent elastic telescopic columns. The rocker arm body 122 is rotatably mounted on each of the two first mounting brackets 120 through the second pins fixed thereon. The two ends of the rocker arm body 122 abut against two adjacent elastic telescopic columns.

[0024] In this embodiment, each rocker arm body 122 abuts against two adjacent elastic telescopic posts at both ends, and each abutment block 123 abuts against its corresponding elastic telescopic post. There are six sets of elastic telescopic posts here. Figure 1 , 4 As shown; When the assembly block 117 moves down, the two sets of first mounting brackets 120 and second mounting brackets 121 can adaptively deflect with their corresponding first pins 119 as the axis, while the rocker arm body 122 adaptably moves with the second pin as the axis. If the elastic telescopic column contacts the wiring terminals of different thicknesses, the adaptive hot pressing process of several hot pressing head structures is realized under the adaptive transmission action of each structure, ensuring the hot pressing quality. Furthermore, the adaptation of the wiring terminals and the hot pressing head structure further improves the hot pressing quality.

[0025] Example 3

[0026] In another embodiment of this utility model, each elastic telescopic column includes a vertical groove formed on the mounting plate 124, a column body 125 disposed in the vertical groove, wherein a mounting block 126 fixed at the top of the column body 125 abuts against the rocker arm pushing mechanism, and its bottom end is assembled with the hot press head structure; and a spring 127 disposed on the outer wall of the column body 125 between the mounting block 126 and the mounting plate 124, in conjunction with Figure 1 , 2 As shown in Figures 3 and 4, when the hot press head structure contacts the terminal block, the spring 127 is adaptively compressed in conjunction with the transmission characteristics of the rocker push mechanism, so that each terminal block and the hot press head structure maintain a suitable hot press strength. It is worth noting that once the assembly block is pressed down into place, each spring is in static equilibrium, providing a continuous and stable clamping force to each hot press head.

[0027] Furthermore, each hot press head structure includes a hot press head body 128 mounted on the bottom end of the column 125, and a wire 129 provided on the back side of the hot press head body 128 is connected to an external power supply.

[0028] When the wire 129 is energized and the hot press head body 128 is heated, the terminal block is placed between the hot press head body 128 and the pressure plate 114. The hot press head body 128 and the pressure plate 114 can properly clamp the terminal block with the cooperation of various structures and complete the hot pressing operation of the terminal block.

[0029] Furthermore, the hot pressing surfaces of the various hot pressing head bodies 128 have different shapes, combined with... Figure 4 It meets the different heat-pressing requirements of different wiring terminals.

[0032] like Figure 1 , 5As shown, the suction hood 132 is fitted inside the mounting slot on the back plate 112 and faces the several hot press head bodies 128. Therefore, when the suction fan inside the suction box 130 is running, the impurities and dense smoke generated by this device can be drawn into the recovery chamber inside the suction box 130, improving the construction environment. Figure 5 As shown.
