[0002] After the two-wire sensor harness is stripped, the harness end needs to be welded. Generally, U-shaped NTC resistors, copper materials or tinned copper materials are used for welding. During the welding process, the welding materials need to be grabbed and transferred to the corresponding station for correction and cutting, and then transferred to the welding machine for welding. The existing grabbing equipment generally uses a manipulator, but the manipulator grabbing has the following problems: The robot can usually only process one station at a time, that is, after it grabs the welding material, it needs to move to the next station, and it can only continue to operate the next step after completing one step. This step-by-step processing method means that the switching time between stations is long, resulting in waiting time between each station, and parallel processing cannot be achieved; Moreover, the movement of the robot usually involves multi-axis linkage. In order to complete complex tasks from grasping to correction, cutting, welding, etc., the robot needs to accurately control the rotation, movement and angle of multiple axes.

[0044] like Figure 5 The material receiving assembly 5 includes a third workstation 51, which is slidably arranged on the workbench 1. The third workstation 51 is driven by a first servo drive unit 52, and the first servo drive unit 52 is installed on the workbench 1. A fourth finger cylinder 53 is installed on the third workstation 51, and two clamping jaws of the fourth finger cylinder 53 can be moved to be arranged side by side with the second clamping plate 45 and the second clamping seat 44.

[0045] The first servo drive unit 52 can drive the third workstation 51 to move, and the third workstation 51 can drive the fourth finger cylinder 53 to move side by side with the second clamping plate 45 and the second clamping seat 44. When the third finger cylinder 94 grabs the NTC resistor to the fourth finger cylinder 53, the fourth finger cylinder 53 can clamp the NTC resistor, and then the first servo unit drives the third workstation 51 to move again, so that the fourth finger cylinder 53 transfers the NTC resistor to the grabbing component 6 for grabbing.

[0046] like Figure 3 and Figure 6 The control component 9 includes a shell 95, which is mounted on the workbench 1. A turntable 96 is rotatably connected inside the shell 95, and the turntable 96 is driven by a motor. The first workstation 31 and the second workstation 41 are located between the shell 95 and the grabbing component 6. The turntable 96 is eccentrically rotatably connected to a crank 97, and the crank 97 is connected to the first mounting plate 91. The two inner side walls of the shell 95 are commonly connected to a guide rod 98, which is arranged along the length direction of the workbench 1. The guide rod 98 is slidably connected to a transverse block 99, and the crank 97 passes through the transverse block 99 and extends from the bottom of the shell 95.

[0047] When the crank 97 is located at the top of the turntable 96, the first mounting plate 91 is in an ascending state; When the turntable 96 rotates 90 degrees in one direction, the lateral block 99 moves horizontally, so that the crank 97 can simultaneously realize the lateral movement and vertical descending action. At this time, the first mounting plate 91 is in a descending state, the first finger cylinder 92 aligns the two clamping claws of the fifth finger cylinder 25, the second finger cylinder 93 aligns the first clamping seat 34 and the first clamping plate 35, and the third finger cylinder 94 aligns the second clamping seat 44 and the second clamping plate 45; After the first finger cylinder 92, the second finger cylinder 93 and the third finger cylinder 94 grab the corresponding NTC resistors, the turntable 96 is reset. Then when the turntable 96 rotates 90 degrees in the other direction, the transverse block 99 moves laterally, so that the crank 97 can simultaneously realize the lateral movement and vertical descent. At this time, the first mounting plate 91 is in a descending state, the first finger cylinder 92 is aligned with the first clamping plate 35 and the first clamping seat 34, the second finger cylinder 93 is aligned with the second clamping plate 45 and the second clamping seat 44, and the third finger cylinder 94 is aligned with the two clamping claws of the fourth finger cylinder 53. It is only necessary to control the rotation angle of the turntable 96, and then realize that multiple cylinders are simultaneously aligned with different workstations for grabbing. The control logic is simple, with efficient parallel processing capabilities, and can achieve precise synchronous control.

[0048] like Figure 5 The grabbing assembly 6 includes a second mounting plate 61, which is mounted on the workbench 1. A lifting slide 62 is slidably connected to the second mounting plate 61. The lifting slide 62 is driven by a second servo drive unit 63. The second servo drive unit 63 is mounted on the second mounting plate 61. The lifting slide 62 is installed with a driving motor 64. The driving motor 64 is connected to a rodless cylinder 65. The rodless cylinder 65 is connected to a sixth finger cylinder 66. The rodless cylinder 65 and the sixth finger cylinder 66 are arranged on the side of the second mounting plate 61 facing the shell 95, and the driving motor 64 is installed on the side of the second mounting plate 61 away from the shell 95.

[0049] When the material receiving component 5 moves to the bottom of the sixth finger cylinder 66, the driving motor 64 drives the rodless cylinder 65 to rotate to a vertical state, and then the rodless cylinder 65 drives the sixth finger cylinder 66 to move close to the material receiving component 5, and grabs the NTC resistor on the material receiving component 5, and then the driving motor 64 and the rodless cylinder 65 cooperate to drive the sixth finger cylinder 66 to reset. When the wiring harness is transferred to the spot welding component 7, the driving motor 64 drives the rodless cylinder 65 to rotate to a horizontal state, and at the same time, the rodless cylinder 65 drives the sixth finger cylinder 66 to move, so that the NTC resistor moves to the spot welding component 7 and docks the wiring harness end.

[0050] like Figure 7 , Figure 8 and Fig. 9The spot welding assembly 7 includes a lifting frame 71, which is installed on the workbench 1 and is located between the wire transmission assembly 8 and the fourth finger cylinder 53. A first lifting plate 72 is arranged between the lifting frames 71, and the first lifting plate 72 is driven by a third servo drive unit 718, and the third servo drive unit 718 is installed on the workbench 1. The top of the first lifting plate 72 is bolted to a first insulating plate 73, and the top of the first insulating plate 73 is bolted to a lower electrode plate 74, and a lower electrode column 75 is installed on the top of the lower electrode plate 74. Both sides of the NTC resistor can be placed on the lower electrode column 75 at the same time. The lifting frame 71 is slidably connected to a second lifting plate 76, and the second lifting plate 76 is located above the first lifting plate 72. A fourth cylinder 77 is installed on the top of the lifting frame 71, and the fourth cylinder 77 is connected to the second lifting plate 76; The second lifting plate 76 is slidably connected to a sliding plate 78 on one side facing the wire transmission assembly 8, the sliding plate 78 is bolted with a second insulating plate 710, the second insulating plate 710 is connected to an upper electrode plate 711 on one side facing away from the sliding plate 78, and the upper electrode column 712 is connected to the upper electrode plate 711 on one side facing away from the second insulating plate 710; The second lifting plate 76 is provided with a sliding groove 761, one end of the sliding plate 78 passes through the sliding groove 761 and extends to the side of the second lifting plate 76 away from the second insulating plate 710, and the side of the second lifting plate 76 away from the second insulating plate 710 is installed with a fourth servo drive unit 713, and the sliding plate 78 is driven to move laterally by the fourth servo drive unit 713; The second lifting plate 76 is also equipped with two fixed rods 714. The upper electrode plate 711 is located between the fixed rods 714 and the fourth servo drive unit 713. The two fixed rods 714 are jointly penetrated by a pressure plate 715. The fixed rods 714 are sleeved with a spring 716. One end of the spring 716 is fixed to the fixed rods 714, and the other end of the spring 716 is fixed to the pressure plate 715. The pressure plate 715 is fixed with a pressure head 717.

[0051] During welding, the third servo drive unit 718 controls the first lifting plate 72 to rise, and the first lifting plate 72 drives the first insulating plate 73 to rise, so that the lower electrode column 75 rises and contacts the NTC resistor. At the same time, the fourth cylinder 77 drives the second lifting plate 76 to descend, and the second lifting plate 76 drives the second insulating plate 710 to descend, so that the upper electrode column 712 cooperates with the lower electrode column 75 to press one side of the NTC resistor together, and then the upper electrode column 712 and the lower electrode column 75 are energized to realize welding one side of the NTC resistor with a wire core of the wiring harness; Then the fourth cylinder 77 drives the second lifting plate 76 to rise, and then the fourth servo drive unit 713 drives the second insulating plate 710 to move horizontally, so that the upper electrode column 712 is aligned with the other side of the NTC resistor, and then the fourth cylinder 77 drives the second lifting plate 76 to descend again, so that the upper electrode column 712 cooperates with the lower electrode column 75 to press the other side of the NTC resistor, and then the upper electrode column 712 and the lower electrode column 75 are energized to weld the other side of the NTC resistor to the other wire core of the wiring harness, completing the welding of the wiring harness, and by controlling the displacement of the upper electrode column 712, only one side of the NTC resistor is welded each time, avoiding the short circuit caused by welding both sides of the NTC resistor at the same time, thereby reducing the possibility of equipment failure.

[0052] Furthermore, before the upper electrode column 712 and the lower electrode column 75 jointly press the NTC resistor, the pressure head 717 contacts the front end of the wiring harness. As the second lifting plate 76 continues to descend, the pressure plate 715 moves on the fixing rod 714, and the spring 716 is in a compressed state, so that the pressure head 717 presses the front end of the wiring harness, strengthening the fixation of the wiring harness and ensuring that the wiring harness maintains a good contact surface during the subsequent welding process, avoiding poor contact due to looseness or offset, thereby improving the strength and reliability of welding.

[0053] like Figure 8 and Fig. 9 The wire transmission assembly 8 includes a transmission seat 81, which is located on the right side of the workbench 1. The transmission seat 81 is arranged along the width direction of the workbench 1. A transmission table 82 is slidably arranged on the transmission seat 81. The transmission table 82 is driven by a fifth servo drive unit 83, and the fifth servo drive unit 83 is installed on the transmission seat 81. Two groups of first clamping blocks 84 and two groups of second clamping blocks 85 are installed on the transmission table 82. Each group of first clamping blocks 84 corresponds to each group of second clamping blocks 85 one by one. The number of each group of first clamping blocks 84 is four. Two first clamping blocks 84 are arranged on one side of the transmission table 82, and the other two first clamping blocks 84 are arranged on the other side of the transmission table 82. The first clamping blocks 84 on both sides of the transmission table 82 correspond to each other one by one. The four first clamping blocks 84 can abut against the side of the attached plate at the same time, and each first clamping block 84 corresponds to a corner of the attached plate. There are two second clamps 85 in each group, and the two second clamps 85 are arranged along the length direction of the conveying platform 82. The two second clamps 85 are arranged opposite to each other, and the tops of the opposite sides of the two second clamps 85 are set as guide surfaces 851. The two second clamps 85 can abut against the two end surfaces of the attachment plate at the same time. The first clamp 84 is used to abut against the side of the attachment plate, and the second clamp 85 is used to abut against the end of the attachment plate. A positioning plate 86 is provided on the side of the conveying platform 82 close to the spot welding assembly 7. The positioning plate 86 is arranged along the length direction of the conveying platform 82. The positioning plate 86 is provided with a plurality of positioning grooves 861 corresponding to the grooves on the attachment plate, and the front end of the wiring harness is located in the positioning groove 861.

[0054] Before welding, multiple wire harnesses will be arranged on the attachment plate. The attachment plate is manually pressed down along the guide surface 851 of the second clamp 85 so that the attachment plate can be quickly fixed between the corresponding first clamp 84 and second clamp 85. At the same time, the welding end of each wire harness can fall into the positioning groove 861. While fixing the attachment plate, the welding end of the wire harness is also positioned. After each wire harness is welded, the fifth servo drive unit 83 drives the conveying table 82 to move, so that the next wire harness can be transferred to the spot welding assembly 7 for welding.

[0055] The implementation principle of the embodiment of the present application is: through the rotation of the turntable 96, the movement of the first finger cylinder 92, the second finger cylinder 93 and the third finger cylinder 94 can be controlled simultaneously, and each finger cylinder can be aligned with a different workstation at the same time, so that the NTC resistor can be processed and transported in parallel, thereby improving the processing efficiency. At the same time, the control system logic is simple, the grasping control system is simplified, the occurrence of failures is reduced, and maintenance is facilitated.

[0056] 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.
