[0028] As a specific embodiment of the improvement, if the individual deformation strip on the end of the main body shell cannot be expanded due to excessive inward bending or rapidly elastically recovers to inward bending after being expanded, the waterproof ring cannot be smoothly loaded into the main body shell, or if the waterproof ring feeding assembly 7 fails to feed the waterproof ring in time, the waterproof ring is not loaded into the main body shell. To solve the above problems, as shown in Figures 1 to 3 The first detector 12 is used for visual detection and is fixedly connected to the static disc 23 through a support. Whether the waterproof ring is loaded is observed through the first detector 12 and information is fed back to the controller. If the waterproof ring is assembled in place, the subsequent components normally perform corresponding operations on the main body shell. If the waterproof ring is not assembled in place, the subsequent components will not perform corresponding operations on the main body shell, until the main body shell moves to the unloading station 229, and then the unloading assembly 9 collects the main body shell into a defective product box. This design can make corresponding operations in time according to the assembly condition of the waterproof ring, further improve the assembly efficiency, and avoid useless work.

[0029] As a specific embodiment of the improvement, as shown in Figures 1 to 3 The second detector 13 is used for visual detection and is fixedly connected to the static disc 23 through a support. Whether the assembled waterproof joint meets the requirements is observed through the second detector 13 and is fed back to the controller. If the waterproof joint is assembled in place, the subsequent unloading assembly 9 collects the waterproof joint into a finished product box. If there is a problem in the assembly of the waterproof joint, the subsequent unloading assembly 9 collects the waterproof joint into a defective product box. This design can comprehensively check the assembled waterproof joint and facilitate the classification and collection of the waterproof joint by the unloading assembly 9, saving the manual operation of manual sorting and effectively improving the collection efficiency.

[0030] As a specific embodiment of the improvement, the waterproof joint at the unloading station 229 is not clamped and moves to the main body feeding station 221, which is easy to cause processing accidents and damage the corresponding components. To solve the above problems, as shown inFigure 1 and Figure 2 As shown in the figure, the work station 22 further comprises a third detection work station 26 between the unloading work station 229 and the main body loading work station 221, the static disc 23 is provided with a third monitor 14 corresponding to the third detection work station 26, the third monitor 14 adopts visual detection and is fixedly connected with the static disc 23 through a support, if the third detection work station 26 is provided with a waterproof joint, each component stops working and an alarm is sent by the controller, so as to facilitate the staff to maintain in time, if the third detection work station 26 is not provided with a waterproof joint, each component normally operates, such design can stop in time and maintain when problems occur, indirectly improve the assembly efficiency, at the same time improve the safety, ensure the safe use of each component, and indirectly reduce the use cost of enterprises.

[0031] As a specific embodiment of the improvement, the prior art unloading assembly places the waterproof joints on the guide plate in the shape of an inverted V for classification and collection through a mechanical hand, but has defects, the mechanical hand needs to move different distances in different directions when classifying the waterproof joints, the operation to be performed by the mechanical hand is complex, is easy to cause faults, and causes the phenomenon of disordered collection of the waterproof joints, in order to solve the foregoing problems, with reference to Figure 4As shown, the discharging assembly 9 comprises a collecting box 91, a distributing cylinder 92, a distributing channel 93, a discharging manipulator 94 and a third support 95. The collecting box 91 is positioned on the workbench 1. The distributing cylinder 92 is positioned on the workbench 1 through the support and the output shaft is parallel to the horizontal plane. The distributing channel 93 is inclined relative to the horizontal plane and is fixedly connected with one end of the distributing cylinder 92. The end of the distributing channel 93 connected with the distributing cylinder 92 is located directly above the collecting box 91 and the other end of the distributing channel 93 extends to the edge of the workbench 1. A finished product box can be arranged on one side of the workbench 1. The finished product box corresponds to the end of the distributing channel 93 located at the edge of the workbench 1. The third support 95 is fixedly connected with the workbench 1. The discharging manipulator 94 is fixedly connected with the top end of the third support 95. In the initial state, one end of the distributing channel 93 is located directly above the collecting box 91 and the discharging manipulator 94 is located directly above the discharging station 229. If the waterproof connector has no defects, the discharging manipulator 94 clamps the waterproof connector at the discharging station 229 and moves to above the collecting box 91 and releases. The waterproof connector falls into the distributing channel 93 and slides along the distributing channel 93 to the finished product box and is collected. If the waterproof connector has defects, the distributing cylinder 92 drives the distributing channel 93 to move to the position so that the distributing channel 93 is staggered with the collecting box 91 in the vertical direction. The discharging manipulator 94 clamps the waterproof connector at the discharging station 229 and moves to above the collecting box 91 and releases. The waterproof connector directly falls into the collecting box 91 and is collected. Then the discharging manipulator 94 and the distributing channel 93 are restored to the initial state. This design can ensure that the direction and distance of the movement of the discharging manipulator 94 are the same each time, simplifies the complexity of the operation of the discharging manipulator 94, reduces the failure rate and indirectly improves the accuracy of the classification and collection of the waterproof connectors.

[0032] As an improved specific embodiment, because the distributing channel 93 has a large volume and the end of the distributing channel 93 frequently rubs against the surface of the workbench 1, the connection stability between the distributing channel 93 and the output shaft of the distributing cylinder 92 can be poor or the distributing channel 93 can be locally bent, which can cause the distributing channel 93 to be inclined left and right. This can affect the accuracy of the classification and collection of the waterproof connectors. To solve the foregoing problem, with reference to Figure 4As shown, the third support 95 comprises a connecting block 96 connected with the blanking manipulator 94, two parallel supporting legs 97 connecting the connecting block 96 with the workbench 1, and two guide rings 98 respectively fixedly sleeved on the two supporting legs 97. The distribution channel 93 is integrally formed with a guide plate 99 on one side. The distance between the two guide rings 98 is matched with the thickness of the guide plate 99. When the distribution cylinder 92 drives the distribution channel 93 to be staggered relative to the collecting box 91, one end of the guide plate 99 penetrates the gap between the two guide rings 98, and the opposite two surfaces of the guide plate 99 respectively slide relative to the outer walls of the two guide rings 98. When the distribution cylinder 92 drives the distribution channel 93 to move above the collecting box 91, the opposite two surfaces of the guide plate 99 respectively slide relative to the outer walls of the two guide rings 98, until one end of the guide plate 99 is separated from the gap between the two guide rings 98, and then the distribution channel 93 is moved to the position. The design can provide a guide for the movement of the distribution channel 93, ensure the structural stability of the distribution channel 93 and the connection stability of the distribution channel 93 and the distribution cylinder 92, and effectively improve the accuracy of the classification and collection of waterproof joints.

Any technical scheme falling within the concept of the utility model belongs to the protection scope of the utility model. It should be noted that some improvements and decorations made by ordinary technical personnel in the technical field without departing from the principles of the utility model are also considered as the protection scope of the utility model.
