At this time, the insertion robot 61 is started to insert a plurality of pins 170 on the terminal body 150, so as to realize the processing of the pins 170 and perform the processing of a group of terminal bodies 150 at one time, which is convenient to operate and improves work efficiency.

[0045] Reference Figure 2 and Figure 4 , wherein the moving assembly 70 includes a moving motor 71, a moving screw 72, a moving block 73, a moving cylinder 74 and a moving rod 75. The moving motor 71 is installed on the workbench 10, the moving screw 72 is horizontally arranged, and one end of the moving screw 72 is coaxially fixed with the output end of the moving motor 71, and the moving block 73 is sleeved on the moving screw 72 and threadedly connected to the moving screw 72.

[0046] Reference Figure 2 and Figure 4 The moving cylinder 74 is fixed on the moving block 73, and the moving rod 75 is arranged along the length direction of the receiving platform 62. The moving rod 75 is fixed to the output end of the moving cylinder 74. The moving cylinder 74 is used to drive the moving rod 75 to move toward or away from the receiving platform 62. A plurality of partition rods 751 are provided on the moving rod 75. The partition rods 751 are perpendicular to the moving rod 75. The partition rods 751 are horizontally arranged and can abut against the top wall of the receiving platform 62 and slide on the receiving platform 62. A plurality of partition rods 751 are arranged at intervals along the length direction of the moving rod 75. The terminal body 150 can be relatively inserted between adjacent partition rods 751. The partition rods 751 are used to push the terminal body 150 to move.

[0047] In the initial state, the partition rod 751 is located on one side of the receiving platform 62. When a group of terminal bodies 150 are placed on the receiving plate 53 and the receiving plate 53 moves to be aligned with the receiving platform 62, the moving motor 71 is started to drive the moving screw 72 to rotate, so that the moving block 73 moves with the moving cylinder 74 toward the receiving plate 53 until the gap between the adjacent partition rods 751 at the end is aligned with the terminal body 150 on the receiving plate 53. At this time, the moving cylinder 74 is started to move the moving rod 75 toward the receiving platform 62, so that the terminal body 150 is relatively inserted between the adjacent partition rods 751. Then the moving motor 71 is exhausted again, driving the moving screw 72 to reverse, driving the moving rod 75 to reset, so that the dividing rod pushes the terminal body 150 to move, thereby realizing a group of terminal bodies 150 moving from the receiving plate 53 to the receiving platform 62.

[0048] During this process, a group of terminal bodies 150 that had already been installed with pins 170 on the receiving platform 62 are also relatively inserted between other adjacent dividing rods 751, and then moved away from the receiving platform 62 under the push of the dividing rods, thereby being transported out of the receiving platform 62, thereby realizing the loading and unloading of the terminal bodies 150 on the receiving platform 62.

[0049] Reference Figure 4 When the insertion robot 61 inserts the pin 170 into the terminal body 150, the pin 170 cannot be completely embedded in the terminal body 150, that is, the top of the pin 170 will protrude from the terminal body 150. In order to cut off the protruding pin 170, a cutting component 110 is provided on the workbench 10, and the receiving platform 62 includes a fixed platform 622 and a movable platform 623. The fixed platform 622 is fixed to the workbench 10, and the movable platform 623 is connected to the cutting component 110.

[0050] Reference Figure 4 The truncation assembly 110 includes a flip motor 111, a flip plate 112, a connecting cylinder 113, a truncation cylinder 114 and a truncation plate 115. The flip motor 111 is fixedly mounted on the workbench 10 by bolts. The flip plate 112 is fixed to the output end of the flip motor 111. The flip motor 111 is used to drive the flip plate 112 to rotate. The flip plate 112 is provided with a receiving groove 1121 for inserting the terminal body 150. The connecting cylinder 113 is fixed to the flip plate 112, and the output end of the connecting cylinder 113 is fixed to the movable table 623.

[0051] Reference Figure 4 The cut-off cylinder 114 is fixed on the workbench 10 , the cut-off plate 115 is located below the flip plate 112 , and the cut-off plate 115 is fixed to the output end of the cut-off cylinder 114 , and the cut-off cylinder 114 is used to drive the cut-off plate 115 to move toward or away from the flip plate 112 .

[0052] When a group of terminal bodies 150 with installed pins 170 on the fixed platform 622 are moved to the movable platform 623 driven by the partition rod 751, the connecting cylinder 113 is started to pull the movable platform 623 to move to the flip plate 112. At this time, the movable platform 623 and the terminal body 150 are embedded in the accommodating groove 1121. Then the flip motor 111 is started to drive the flip plate 112 to rotate 180°, that is, the flip plate 112 is turned upside down, so that the terminal body 150 originally facing upward becomes facing downward. Under the restriction of the accommodating groove 1121, the terminal body 150 will not fall out of the accommodating groove 1121 under the action of gravity.

[0053] Then, the cutting cylinder 114 is started to drive the cutting plate 115 to move toward or away from the flip plate 112 , so that the cutting plate 115 abuts and slides on the side wall of the terminal body 150 , thereby breaking off the protruding pins 170 and improving the processing quality of the pins 170 .

[0054] Reference Figure 4 and Figure 6 The connecting channel 80 is provided with a plurality of mounting grooves 81, which are evenly distributed along the length direction of the connecting channel 80. The terminal body 150 can be inserted into the mounting grooves 81. A transfer plate 120 is slidably connected to the workbench. The connection method between the transfer plate 120 and the workbench 10 is the same as that of the receiving plate 53, and both are driven by a lead screw motor. The structure of the transfer plate 120 is also completely consistent with that of the receiving plate 53, and no further details are given here. When the partition rod 751 pushes the terminal body 150 to move, the terminal body 150 can move from the receiving platform 62 to the transfer plate 120.

[0055] Reference Figure 4 and Figure 6 A push cylinder 130 is provided on the workbench 10, and a push pin 131 is fixed to the output end of the push cylinder 130. The push pin 131 can abut against the end wall of the terminal body 150 on the transfer plate 120 to push the terminal body 150 onto the connecting channel 80 in sequence. When the protruding pin 170 on the terminal body 150 is cut off, the connecting cylinder 113 pushes the movable platform 623 to reset, so that the group of terminal bodies 150 can be inserted between adjacent partition rods 751, and moved to the transfer plate 120 under the push of the partition rod 751, and then the transfer plate 120 is moved so that one of the terminal bodies 150 is aligned with the connecting channel 80. At this time, the pushing cylinder 130 is started to drive the ejector pin 131 to push the terminal body 150 onto the connecting channel 80 and insert it into a mounting groove 81. Then the transfer plate 120 is continuously moved so that the terminal body 150 is aligned with the connecting channel 80 in turn, and the pushing cylinder 130 is used to send the terminal body 150 to the connecting channel 80 in turn, so that a plurality of terminal bodies 150 are in the same state and move in turn, so as to facilitate subsequent processing and improve work efficiency.

[0056] Reference Figure 2 and Figure 6 The processing assembly 90 includes two processing positions 91, which are arranged opposite to each other. One of the processing positions 91 is used to install the fixing plate 180 on one end of the terminal body 150, and the other processing position 91 is used to process the other end of the terminal body 150. A sheet strip 181 composed of a plurality of fixing plates 180 is provided on the processing position 91. The processing position 91 includes a mounting frame 911, a sliding block 912, a clearance cylinder 913, a mounting cylinder 914, a connecting rod 915 and a cutting knife 9151. The mounting frame 911 is fixed on the workbench 10, and the sliding block 912 is slidably connected to the mounting frame 911. The sliding block 912 is used to drive the fixing plate 180 to move in the direction of the connecting channel 80.

[0057] Reference Figure 2 and Figure 6 The yielding cylinder 913 is mounted on the workbench 10 by bolts, and the mounting cylinder 914 is mounted on the output end of the yielding cylinder 913. The yielding cylinder 913 is used to drive the mounting cylinder 914 to move toward or away from the connecting channel 80. The connecting rod 915 is fixed to the output end of the mounting cylinder 914, and the connecting rod 915 can abut against the end wall of the terminal body 150, and the cutting knife 9151 is fixed to the connecting rod 915, and the cutting knife 9151 is used to cut the sheet belt 181, and the fixing sheet 180 is mounted on the end wall of the terminal body 150.

[0058] In the initial state, the giving way cylinder 913 drives the installation cylinder 914 to drive the connecting rod 915 to be located on one side of the connecting channel 80, so that the connecting rod 915 will not interfere with the movement of the terminal body 150 on the connecting channel 80. When the connecting channel 80 drives the terminal body 150 to move to the mounting frame 911, the sliding block 912 is moved to drive the strip 181 to move downward until the fixing plate 180 at the bottom is aligned with the end of the terminal body 150. Then the giving way cylinder 913 is started to drive the installation cylinder 914 to move toward the connecting channel 80 until the connecting rod 915 is inserted between adjacent terminal bodies 150. During the movement of the connecting rod 915, the cutting knife 9151 is driven to move, cutting the strip 181, so that the fixing plate 180 at the lowest end is separated from the entire strip 181. Then, the installation cylinder 914 is started to drive the connecting rod 915 to move toward the installation frame 911, so that the fixing piece 180 is abutted against the end wall of the terminal body 150, and the installation groove 81 fixes the position of the terminal body 150 to achieve the installation of the fixing piece 180. When the terminal body 150 moves to another installation frame 911, the fixing piece 180 at the other end of the terminal body 150 is installed.

[0059] Reference Figure 6 and Figure 7When the fixing piece 180 is installed on the terminal body 150, a pin 170 at the end of the terminal body 150 is squeezed out, so that the pin 170 extends out of the terminal body 150. In order to cut off the extended pin 170, a cutting assembly 140 is provided on the workbench 10. The cutting assembly 140 includes a cutting cylinder 141, a cutting block 142, a cutting motor 143 and a cam 144. The cutting cylinder 141 is installed on the workbench 10. A moving frame 1411 is fixed on the output end of the cutting cylinder 141. The cutting cylinder 141 is used to drive the moving frame 1411 to move toward or away from the connecting channel 80. Reference Figure 6 and Figure 7 A horizontally arranged limit rod is fixed on the moving frame 1411, and the cutting block 142 is penetrated by the limit rod and can slide on the limit rod. A positioning groove 1421 for inserting the protruding pin 170 is provided on the side of the cutting block 142 close to the connecting channel 80, and a fixing hole 1422 is provided on the side of the cutting block 142 away from the connecting channel 80, and the cam 144 is inserted into the fixing hole 1422 and can rotate in the fixing hole 1422. The cam 144 is coaxially fixed with the cutting motor 143, and the cutting motor 143 is fixed on the moving frame 1411 by bolts.

[0060] When the terminal body 150 moves to the cutting block 142, the cutting cylinder 141 is started to drive the cutting block 142 to move in the direction close to the connecting channel 80 until the protruding pin 170 is relatively inserted into the positioning groove 1421. At this time, the cutting motor 143 is started to rotate the cam 144. When the tip of the cam 144 is facing the vertical direction, the inner walls on both sides of the fixing hole 1422 in the vertical direction abut against the side walls of the cam 144. Therefore, when the cam 144 rotates to abut against the inner wall of the fixing hole 1422 in the vertical direction, the cam 144 applies a thrust to the inner wall of the fixing hole 1422, thereby driving the cutting block 142 to move horizontally, so that the positioning groove 1421 applies a thrust to the pin 170 until the pin 170 is broken off, thereby achieving fine finishing of the terminal body 150 and improving the quality of the terminal.

[0061] The implementation principle of a multi-station terminal plugging device in the embodiment of the present application is as follows: when working, a plurality of terminal bodies 150 and a plurality of end caps 160 are placed in the conveying assembly 20, and then the conveying assembly 20 is started, and the plurality of terminal bodies 150 are moved in the direction of the installation assembly 30 in sequence, and at the same time, the plurality of end caps 160 are also moved in the direction of the installation assembly 30 in sequence, that is, the terminal body 150 and the end cap 160 are moved synchronously. When a single terminal body 150 and a single end cap 160 are moved to the installation assembly 30, the installation assembly 30 is started, and the end cap 160 is installed on the terminal body 150, and then the installed end cap 160 body is sent to the conveying path 40, and is moved from the conveying path 40 to the direction of the receiving assembly 50, until the plurality of terminal bodies 150 are arranged in sequence on the receiving assembly 50.

[0062] When a certain number of terminal bodies 150 are arranged in sequence, a group of terminal bodies 150 is formed, and then the moving component 70 is started to move a group of terminal bodies 150 from the receiving component 50 to the insertion component 60, and then the insertion component 60 processes a group of terminal bodies 150 at the same time to improve work efficiency. When the pins 170 are all inserted into a group of terminal bodies 150, the moving component 70 is used to send the terminal bodies 150 to the connecting channel 80, and the connecting channel 80 is sequentially transported to the processing component 90, and the processing component 90 is started to install the fixing plates 180 on both ends of the terminal body 150, and finally the processing of the terminal is realized. The whole process is realized through automation, without manual participation, with a high degree of mechanization, the terminal is not easy to be damaged, and the processing accuracy is improved.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
