In use, the material handling device 500 can sequentially handle the housings one by one along the first pre-plugging assembly 200, the terminal plugging assembly 300, and the first crimping assembly 400. The housing is firstly pre-inserted and positioned on the first pre-insertion assembly 200, and whether the terminal insertion grooves have the conditions of non-grooving and the like is determined, so that the situation that the terminals directly impact the housing to further cause terminal waste during subsequent insertion is avoided. After the pre-insertion positioning is completed, the housing comes to the side of the terminal insertion assembly 300 and inserts the terminals into the terminal insertion grooves. Finally, the housing brings the terminal to one side of the first riveting component 400, and the first riveting component 400 rivets the terminal, so that the terminal is tightly connected with the housing, the connection stability between the terminal and the housing is improved, and the subsequent terminal is prevented from falling from the terminal slot.

As shown in fig. 1 to 4, in one embodiment, the first pre-plugging assembly 200 includes a first supporting seat 230, a first cylinder 240, a first moving member 250, a first pre-plugging cylinder 260, a first guiding seat 270 and a first pre-plugging block 220;

the first supporting seat 230 is arranged on one side of the housing fixing component 100, the first cylinder 240 is arranged on the first supporting seat 230 along a second preset direction, a cylinder shaft of the first cylinder 240 is connected with the first moving member 250 to enable the first moving member 250 to be movably arranged on the first supporting seat 230 along the second preset direction, the first pre-inserting cylinder 260 and the first guide seat 270 are arranged on the first moving member 250 along the second preset direction, the first guide block 210 is fixed at one end, facing the housing fixing component 100, of the first guide seat 270, the first pre-inserting block 220 is movably arranged on the first guide seat 270, and the cylinder shaft of the first pre-inserting cylinder 260 is connected with the first pre-inserting block 220 to be used for driving the first pre-inserting block 220 to move along the second preset direction.

When the device is used, the first cylinder 240 drives the first moving part 250 to reciprocate along a second preset direction, and further drives components on the first moving part 250 to move; the first pre-plugging cylinder 260 drives the first pre-plugging block 220 to pass through the first guide groove on the first guide block 210, and finally to be plugged into the corresponding terminal slot of the housing. In this way, the first guide groove on the first guide block 210 is located at the same position as the terminal slot corresponding to the housing, so that the first pre-plugging block 220 can be accurately inserted into the terminal slot corresponding to the housing, and the pre-plugging positioning operation can be performed quickly. In addition, the first pre-plugging assembly 200 can also identify the position of the terminal slot on the housing in advance, and the position of the terminal slot on each housing needs to be kept at the correct position if accurate plugging is to be realized due to small, light and thin end faces, and the first pre-plugging assembly 200 can play a role in identifying the terminal slot in advance, thereby being beneficial to subsequent processing operation.

As shown in fig. 1 to 4 and 12, in one embodiment, a square connecting block 221 is disposed at one end of the first pre-plugging block 220 close to the first pre-plugging cylinder 260, and a first spring 222 is disposed between the square connecting block 221 and the first guide seat 270.

When the terminal is used, the first pre-plugging air cylinder 260 drives the first pre-plugging block 220 to move towards the shell, at the moment, under the action of the spring elasticity of the first spring 222, the first pre-plugging block 220 is plugged into the terminal slot, and at the moment, the first spring 222 is not completely compressed; when the first pre-plugging block 220 has been inserted into the terminal slot of the housing, the cylinder shaft of the first pre-plugging cylinder 260 continues to extend toward the housing, so that the first spring 222 starts to compress, and the first pre-plugging block 220 continues to provide a force to the terminal slot under the elastic force of the spring. Because the housing is formed by an injection molding process, residual plastic blocks, plastic particles or plastic blocks are inevitably left in the terminal insertion slot of the housing, and the obstacles may influence the insertion of the terminal or cause scratches on the surface of the terminal. Therefore, the obstacles can be effectively removed by the insertion of the first pre-plugging block 220, if the first pre-plugging block 220 is obstructed by the obstacles to advance when entering, after the first spring 222 is compressed, an elastic force is provided for the first pre-plugging block 220, the acting force of the first pre-plugging block 220 on the terminal slot can be effectively enhanced, and the subsequent terminal plugging can be smoother.

Specifically, one end of the terminal slot of the shell is provided with a protruding structure. In order to fit the housing during the pre-insertion operation, the first guide block 210 has a narrow portion 212 and a wide portion 213, so as to fit the housing. On the other hand, it can be engaged with the end of the pre-insert piece 223 corresponding to the wide portion 213. In this way, the fitting between the pre-insertion piece 223 and the first guide block 210 can be enhanced, so that the pre-insertion piece 223 is accurately inserted into the terminal insertion groove of the housing.

As shown in fig. 5 to 8 and 12, in one embodiment, the terminal insertion assembly 300 includes a second support base 310, a feeding mechanism 320 and an insertion mechanism 330;

the second support seat 310 is disposed on one side of the first pre-insertion assembly 200;

the feeding mechanism 320 comprises a feeding rail 321, a speed-regulating cylinder 322, a first hinging block 323, a first connecting rod 324, a second hinging block 325 and a speed-reducing block 326, the feeding rail 321 is arranged on the second supporting seat 310 along a first preset direction, the speed-regulating cylinder 322 and the second hinging block 325 are arranged on one side of the feeding rail 321, a cylinder shaft of the speed-regulating cylinder 322 is connected with the first hinging block 323, the first hinging block 323 is hinged with one end of the first connecting rod 324, the second hinging block 325 is hinged with the other end of the first connecting rod 324, one end of the first connecting rod 324, which is close to the feeding rail 321, protrudes to form a touch block 3241, the speed-reducing block 326 is movably arranged on the feeding rail 321 and is in contact with the upper surface of the material belt of the double-pin terminal, and the touch block 3241 is in contact with the speed-reducing block 326;

the inserting mechanism 330 is disposed at one side of the feeding mechanism 320.

Specifically, the inserting mechanism 330 is further provided with a positioning mechanism 340. The positioning mechanism 340 comprises a positioning cylinder 341, a positioning block 342 and a positioning pin 343, the positioning cylinder 341 is arranged on the insertion mechanism 330, the cylinder shaft of the positioning cylinder 341 is connected with the positioning block 342, and the positioning pin 343 is arranged on the positioning block 342. In this manner, the terminals can be efficiently positioned and held in a horizontal state for direct insertion into the housing. Since a horizontal pin of the two-pin terminal needs to be inserted into and extended from the housing, the horizontal pin of the two-pin terminal has a certain length, so that the center of gravity of the two-pin terminal is deviated to the horizontal pin, and the two-pin terminal cannot hold a horizontal device without the positioning mechanism 340, and cannot be inserted into the housing smoothly. The end surface of the positioning block 342 facing the two-pin terminal is disposed as a flat surface for the purpose of contacting the material strip section of the two-pin terminal, thereby ensuring that the two-pin terminal is maintained in a horizontal state before insertion. In addition, the insertion portion of the two-pin terminal needs to be arranged at high speed for smooth insertion.

In addition, the end face of the deceleration block 326 facing the two-pin terminal is not a complete plane, but is composed of two planes with different slopes, and the slope of the plane close to the insertion platform is larger. When the terminal passes through the speed reducing block 326, the speed regulating cylinder 322 controls the contact block 3241 of the first connecting rod 324 to contact with the speed reducing block 326, so that the contact block 3241 provides a pressure to the speed reducing block 326, and the friction force between the speed reducing block 326 and the material belt section of the two-pin terminal is increased, thereby reducing the feeding speed of the two-pin terminal.

Further, the positioning pins on the positioning mechanism 340 need to be inserted into the insertion holes of the ribbon section of the two-pin terminal. The locating pins cannot be inserted directly during the terminal loading process, and additionally, portions of the terminals begin to empty as the speed reducer block 326 transitions into the insertion mechanism 330. If the terminal feeding speed is too fast at this time, the positioning pin is easily caused to be incapable of aligning with the material belt section of the double-pin terminal, so that the positioning is failed, and the insertion is influenced. Therefore, the deceleration block 326, the positioning mechanism 340 and the inserting mechanism 330 cooperate to position the terminals and ensure that the terminals can be inserted smoothly.

When the device is used, the feeding mechanism 320 controls the feeding of the dual-pin terminals and feeds the dual-pin terminals onto the inserting mechanism 330, the positioning mechanism 340 rapidly positions the dual-pin terminals, and the inserting mechanism 330 inserts the terminals into the housing of the housing fixing component 100.

As shown in fig. 5 to 8 and 12, in an embodiment, a blanking opening is formed on the feeding rail 321, a first cutting block 3211 is disposed at one end of the blanking opening, a cutting cylinder 351 is disposed on the second support seat 310, and a cylinder shaft of the cutting cylinder 351 is indirectly connected to a second cutting block 352. When in use, the first cutting block 3211 is matched with the second cutting block 352 to cut the protection pins on the dual-pin terminal, and then the cut protection pins are blanked through the blanking port. In addition, the speed of the speed reducing block 326 is reduced, which is beneficial to reducing the feeding speed of the dual pin terminal, so that enough time is provided for the second cutting block 352 to be matched with the first cutting block 3211 in a cutting manner.

As shown in fig. 5 to 8 and 12, in one embodiment, the inserting mechanism 330 includes an inserting cylinder 331, a second moving member 332, an inserting platform 333, a stopping cylinder 334, a matching sliding block 335 and a stopping block 336;

the inserting cylinder 331 is arranged on one side of the feeding rail 321 along a second preset direction, a cylinder shaft of the inserting cylinder 331 is connected with the second moving member 332 and used for driving the second moving member 332 to move along the second preset direction, the inserting platform 333 is fixed at one end, close to the shell fixing component 100, of the second moving member 332, the stopping cylinder 334 is arranged on the second support seat 310 along the second preset direction, the cylinder shaft of the stopping cylinder 334 is connected with the matching slide block 335 and used for driving the matching slide block 335 to move along the second preset direction, and the bottom of the stopping block 336 is movably connected with the matching slide block 335 and used for driving the stopping block 336 to pass through the second support seat 310 and move along the third preset direction;

wherein, when the dual pin terminal is loaded to the insertion platform 333, the top of the stop block 336 abuts against the insertion platform 333.

In use, the stop cylinder drives the mating slider 335 to move in the second predetermined direction, thereby lifting the stopper 336 and causing the stopper 336 to abut against the mounting platform 333. Therefore, the insertion platform 333 can be blocked from advancing, and the terminals can be stably loaded onto the insertion platform 333. In addition, when the stop block 336 abuts against the insertion platform 333, a supporting force is provided for the insertion platform 333 to support the insertion platform 333 and balance the pressure of the positioning mechanism 340 on the insertion platform 333.
