For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1 As shown, a connector press-fit welding jig includes a panel 300, on which a wire pressing mechanism 100 and a pushing mechanism 200 are installed. The wire pressing mechanism 100 and the pushing mechanism 200 are arranged relatively to each other. The wire pressing mechanism 100 presses the cable, and the pushing mechanism 200 presses the connecting terminal, and makes the welding end of the connecting terminal overlap with the welding end of the cable. After the welding end of the connecting terminal and the welding end of the cable overlap, the jig is moved as a whole to the next station.

[0024] In this embodiment, if Figure 2 and Figure 3 As shown, the pushing mechanism 200 includes a bottom plate 203, and the bottom plate 203 is mounted on a panel 300. Figure 2 As shown, a positioning groove 206 is provided on one end of the bottom plate 203 near the wire pressing mechanism 100, and a positioning column 210 for pre-positioning the connection terminal is provided in the positioning groove 206. A groove is provided on one side of the positioning column 210. In this embodiment, as shown in FIG. Fig.11 and Fig.12As shown, the middle part 11 of the connecting terminal is a square block, a column 12 is arranged at the bottom of the square block, and an open groove 13 matching the positioning column 210 is opened on the side wall of the bottom of the square block. The robot clamps the connecting terminal and places it in the positioning groove 206. At this time, the column 12 enters the groove to achieve one-time positioning, and then as the connecting terminal is lowered, the positioning column 210 partially enters the open groove 13, thereby positioning the connecting terminal in the left and right directions, but at this time, the connecting terminal can also move forward.

[0025] In this embodiment, if Figure 2 As shown, a sliding groove is provided on the bottom plate 203 located at the rear side of the positioning groove 206, and a push lock 205 is slidably installed in the sliding groove. The push lock 205 can slide back and forth relative to the sliding groove, and a rotatable inner cover plate 201 and an outer cover plate 202 are installed at the rear end of the bottom plate 203. By rotating the inner cover plate 201, the inner cover plate 201 can cover the middle part 11 of the connecting terminal. After the connecting terminal is placed in the positioning groove 206, the connecting terminal is positioned in the left and right directions. By covering the inner cover plate 201 down, the inner cover plate 201 covers the middle part 11 of the connecting terminal, so that the connecting terminal can be pre-pressed in the up and down directions, thereby realizing the pre-positioning of the connecting terminal in the up and down directions.

[0026] In this embodiment, if Figure 7 As shown, the pusher lock 205 includes a pusher plate 221, which is slidably mounted in the sliding groove. The front end of the pusher plate 221 is provided with a locking tooth 224 protruding upward. Figure 7 and 10 As shown, the top of the locking tooth 224 is provided with a tooth head 225 extending forward, and the lower surface of the tooth head 225 forms a limiting step 226. Figure 6 As shown, the rear side wall of the push plate 221 is a wedge-shaped surface, and a pressing piece 204 is provided at the rear end of the outer cover plate 202. The outer cover plate 202 is rotated so that the outer cover plate 202 covers the inner cover plate 201, and during the rotation of the outer cover plate 202, the pressing piece 204 presses the wedge-shaped surface, so that the push plate 221 moves forward. In this embodiment, as shown in FIG. Fig.11 and Fig.12As shown, there is a step groove 14 between two adjacent middle parts 11 of the connecting terminal. When the outer cover plate 202 is in the process of closing, the top pressure member 204 pushes the push plate 221 to move forward, and the tooth head 225 is inserted into the gap between the two adjacent middle parts 11 of the connecting terminal, that is, the tooth head 225 is stuck in the step groove 14, and the limiting step 226 is in contact with the upper surface of the step groove 14. In the process of the push plate 221 moving forward, the push plate 221 pushes the middle part 11 of the connecting terminal to move forward for a distance, so that The rear side wall of the positioning column 210 is in contact with the open groove 13, and when the outer cover 202 is closed, the connection terminal is fixed in the front, back, left, right, up and down positions, thereby preventing the connection terminal from moving relative to the fixture and also preventing the connection terminal from deforming. Even if the connection terminal is deformed, it will be reset by the downward pressure of the outer cover 202 and the pressure of the push-pull lock 205, thereby ensuring the stability of the installation of the connection terminal, thereby ensuring the pre-connection of the connection terminal and the cable, and facilitating the subsequent welding of the connection terminal and the cable.

[0027] In this embodiment, if Figure 2 and Figure 5 As shown, buckles 208 for clamping the outer cover 202 are also provided on the left and right sides of the bottom plate 203, and flanges are provided on both sides of the outer cover 202. Slots are provided at the left and right ends of the bottom plate 203, and the buckles 208 can be rotatably installed in the slots. Further, the buckles 208 have a small swing. Specifically, as shown in FIG. Figure 2 and Figure 5 As shown, a slot is opened on the base plate 203, and the buckle 208 is installed in the slot through a rotating shaft. The installation of the rotating shaft belongs to a conventional setting. For example, an axial hole is opened in the front-to-back direction on the base plate 203, and the axial hole passes through the slot. An axial hole is also opened at the bottom of the buckle 208, and the shaft rod is sleeved in the shaft hole. Furthermore, a torsion spring can be installed on the shaft rod. When the buckle 208 is installed, the buckle 208 contacts the inner wall of the slot under the action of the torsion spring, so that the buckle 208 is a vertical device, and the inner wall of the buckle 208 is set to a circular arc chamfer, and the bottom of the flange is also set to a circular arc shape. When the outer cover plate 202 is pressed down, the flange can exert an external force on the buckle 208, thereby causing the two buckles 208 to expand outward. After the outer cover plate 202 is closed, the buckle 208 can be reset under the action of the torsion spring, thereby locking the flange.

[0028] In this embodiment, if Figure 7 As shown, a limiting notch 222 is provided at the rear end of the push plate 221, and a raised limiting block 209 is provided on the bottom plate 203. The limiting block 209 is located in the limiting notch 222. Since the push plate 221 and the sliding groove are installed in a sliding fit, the push plate 221 can only move in the front and rear directions. In order to prevent the push plate 221 from withdrawing backward from the sliding groove, the limiting block 209 can block the push plate 221, thereby preventing the push plate 221 from withdrawing backward from the sliding groove.

[0029] In this embodiment, if Figure 2 and Figure 7 As shown, a pressure plate is detachably installed on the bottom plate 203 located on the left and right sides of the push plate 221, and the pressure plate can press the push plate 221. When installing the push plate 221, the push plate 221 is placed in the sliding groove, and then the pressure plate is installed on the left and right sides of the push plate 221. The pressure plate just contacts with the push plate 221, or there is a certain gap between the pressure plate and the push plate 221, so that the pressure plate will not affect the forward and backward movement of the push plate 221.

[0030] In this embodiment, if Figure 2 and Figure 6 As shown in the figure, the top pressing member 204 is a glass bead, and more than half of the glass bead is embedded in the bent portion of the outer cover plate 202. Through the glass bead, the top pressing member 204 and the wedge-shaped surface are in point-to-surface contact, so that the top pressing member 204 can exert a thrust on the push plate 221, so that the push plate 221 moves forward, and during the top pressing process, the glass bead can roll along the wedge-shaped surface, so that when the outer cover plate 202 is closed, the push plate 221 can be pushed forward by the glass bead. In this embodiment, The outer cover plate 202 and the inner cover plate 201 are both L-shaped structures, and the bent parts of the outer cover plate 202 and the inner cover plate 201 are their short sides. A notch is provided on the rear side wall of the bottom plate 203, and a rotating shaft is installed in the notch along the left and right directions, and the outer cover plate 202 and the inner cover plate 201 are both mounted on the rotating shaft. Of course, in order to facilitate the installation of the inner cover plate 201 and the outer cover plate 202, corresponding notches are provided on the bent parts, so that the bent parts of the outer cover plate 202 and the inner cover plate 201 are both mounted on the same rotating shaft.

[0031] In this embodiment, if Figure 2 and Figure 4 As shown, the wire pressing mechanism 100 includes a rotating cover plate 101 and a wire carrying plate 102, the wire carrying plate 102 is installed on the panel 300, and a wire groove 103 for placing cables is opened on the wire carrying plate 102. After the rotating cover plate 101 is closed, the rotating cover plate 101 presses the rear end of the cable into the wire groove 103. A fixed support 104 is provided on the panel 300, and the fixed support 104 is located on the left side of the wire carrying plate 102. One end of the rotating cover plate 101 is rotatably mounted on the fixed support 104, and the other end of the rotating cover plate 101 is locked by a locking mechanism. When in use, when the rotating cover plate 101 is opened, the cable is first placed in the wire groove 103, and then the position of the strip cable is made so that the welding end of the cable is in the designated welding area, and then the rotating cover plate 101 is closed, so that the rotating cover plate 101 presses the cable, so that the cable cannot move forward and backward, and finally locked by the locking mechanism, thereby ensuring the stability of the position of the cable during transportation and welding.

[0032] In this embodiment, if Figure 2 and Figure 4 As shown, the locking mechanism includes a locking seat 110, such as Fig. 9 As shown, a limiting groove 112 is provided at the top of the locking seat 110, and a groove is provided at the bottom of the limiting groove 112, which extends downward, and a column 108 is rotatably installed in the groove. Preferably, an axial hole is provided in the front-to-back direction of the locking seat 110, and a shaft rod is passed through the axial hole, and the shaft rod passes through the column 108, so that the column 108 can rotate to a certain extent relative to the locking seat 110, and the top of the column 108 extends upward and protrudes from the limiting groove 112, and a rotating pressure head 108 is rotatably installed on the top of the column 108 7. When the rotating cover 101 is closed, the other end of the rotating cover 101 is a locking end, which is located in the limiting groove 112, and a notch is provided on the locking end for the column 108 to pass through, and a variable diameter arc groove 111 is provided on the top of the locking end. The rotating pressure head 107 has an arc segment that rolls along the arc groove 111. When the rotating pressure head 107 is locked, the pressure block of the rotating pressure head 107 is pressed on the upper surface of the rotating cover 101. When the cover is closed, the rotating pressure head 107 is in an open state and swings to the right. The column 108 is moved to allow the locking end to enter the space of the limiting groove 112, and then the column 108 is reset. Preferably, the width of the locking end matches the width of the limiting groove 112. Therefore, when the locking end enters the limiting groove 112, the rotating cover plate 101 cannot swing in the front and rear directions. Then, the rotating pressure head 107 is turned over, and the arc end of the rotating pressure head 107 rolls in the arc groove 111. During the rolling process, since the arc groove 111 is a variable diameter structure, the arc end and the arc groove 111 are in a variable diameter structure. The distance between the contact point of the arc groove 111 and the rotation center of the rotating pressure head 107 is shrinking, so that the rotating pressure head 107 applies downward pressure to the rotating cover plate 101, so that the rotating cover plate 101 presses the cable. Preferably, after the rotating pressure head 107 is installed in place, the angle between the rotating pressure head 107 and the column 108 does not exceed 90°. At this time, the rotating pressure head 107 has a certain self-locking effect and will not easily turn outward, thereby ensuring the reliability of the rotating cover plate 101 and the wire carrier plate 102.

[0033] In this embodiment, if Figure 8As shown, the locking mechanism also includes a lock buckle 109, which is located on the right side of the locking seat 110. A mounting groove 113 is provided on the panel 300. The lock buckle 109 can be rotatably installed in the mounting groove 113. A locking block is provided on the left end face of the lock buckle 109, and when the lock buckle 109 is locked, the lower end face of the locking block abuts against the limiting groove 112. Further, sinking grooves 114 are provided on the front and rear side walls of the mounting groove 113. The shaft rod on the lock buckle 109 is installed in the sinking groove 114, and a plug 115 is installed on the panel 300. The bottom of the plug 115 abuts against the shaft rod. Therefore, during installation, the shaft rod and the lock buckle 109 can be assembled, and then the lock buckle 109 can be fastened. 9 is placed in the installation groove 113, and then the two ends of the shaft rod are pressed with the plug 115. Similarly, a torsion spring can also be installed on the shaft rod. Under the action of the torsion spring, the lock buckle 109 is in a vertical device. At this time, the lower end face of the lock block abuts against the limiting groove 112. Of course, in order to avoid interference between the column 108 and the lock block, an avoidance groove can be opened on the lock block. Preferably, when the lower end face of the lock block abuts against the limiting groove 112, the column 108 also contacts the groove wall of the avoidance groove, or there is a slight gap between the column 108 and the avoidance groove, so that the lock buckle 109 can limit the swing of the column 108, thereby improving the reliability of the closure of the rotating cover plate 101 and the wire carrier plate 102.

[0034] In this embodiment, if Figure 2 As shown, a stop block 105 is rotatably installed on the panel 300 located on the left side of the fixed support 104. When the stop block 105 is locked, a pin block is provided on the right end face of the stop block 105, and when the stop block 105 is locked, the pin block is inserted into the gap between the fixed support 104 and the rotating cover 101. In the present embodiment, the installation method of the stop block 105 is consistent with that of the lock buckle 109, so the installation of the stop block 105 is no longer described in detail. Instead, the pin block is inserted into the gap between the fixed support 104 and the rotating cover 101. When the rotating cover 101 is closed, if the stop pin is not unlocked by external force, the rotating cover 101 cannot rotate in the opposite direction, thereby ensuring the reliability of the wire pressing mechanism 100.

[0035] In this embodiment, if Figure 2 As shown, a receiving groove is also provided at the front end of the bottom plate 203 to facilitate the welding end of the cable to pass through.

[0036] In this embodiment, if Figure 1 As shown, in order to facilitate the taking of the jig, an extraction mechanism 400 is also installed at the left end of the panel 300. The extraction mechanism 400 includes a support plate connected to the panel 300, and handles are installed on the left and right sides of the support plate.

[0037] The working process of the present invention is as follows: first, place the connecting terminal in the positioning groove 206 to achieve pre-positioning of the connecting terminal, then put down the inner cover plate 201, the inner cover plate 201 presses the middle part 11 of the connecting terminal, and then place the cable in the wire groove 103 so that the welding end of the cable overlaps with the welding end of the connecting terminal, then press the cable by rotating the cover plate 101, and lock the cover plate 101 by rotating the locking mechanism, and finally put down the outer cover plate 202, and the outer cover plate 202 is clamped by the buckle 208, so as to ensure the reliability of the overlap between the welding end of the cable and the welding end of the connecting terminal.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. 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.
