In addition, the feeding unit comprises a plastic sleeve feeding unit (second feeding unit), which comprises an electric vibrating hopper (not shown in the figure), a plastic sleeve feeding groove 206 and a plastic sleeve feeding groove cylinder 208. The electric vibrating hopper is not limited in structure and is used for vibrating the plastic sleeve. The electric vibrating hopper is connected with a pipeline or a guide rail, the pipeline or the guide rail is used for conveying the plastic sleeve placed in the electric vibrating hopper to a through hole of the plastic sleeve feeding groove cylinder 208, the plastic sleeve feeding groove cylinder 208 is used for conveying the plastic sleeve into the plastic sleeve feeding groove 206 through the plastic sleeve electric vibrating guide inlet groove 207, and the plastic sleeve is pushed into the round hole of the hinge plate by the long punch.

[0041] The feeding cylinder 203 and the plastic sleeve feeding groove cylinder 208 are arranged on the two sides of the conveying belt 201, the feeding cylinder 203 is used for pushing the hinge plate onto the conveying belt 201, one end of the plastic sleeve feeding groove cylinder 208 is provided with a through hole for containing the plastic sleeve, and the plastic sleeve feeding groove cylinder 208 drives the plastic sleeve to move and convey the plastic sleeve into the plastic sleeve feeding groove 206.

[0042] The feeding-to-position station one refers to the position of the plastic sleeve entering the hinge plate assembly detection device through the pipeline connected with the electric vibrating hopper, and the plastic sleeve feeding unit can also be provided with a vibrating hopper guide rail connected with the electric vibrating hopper, and the vibrating hopper guide rail can be directly used for conveying the plastic sleeve.

[0043] The hinge plate feeding device 200 comprises up-down and left-right moving power devices, which comprise a lifting three-axis cylinder 103, a vertically arranged guide sliding table 106, and a guide column 107. The lifting three-axis cylinder 103 and the guide sliding table 106 are fixed on the vertical plate 101, and the lifting three-axis cylinder 103 and the vertically arranged guide sliding table 106 are connected and fixed through a lifting crossbeam 102.

[0044] A limiting nut 108 is arranged at the lower end of the guide column 107, which is used to limit the downward movement distance of the guide column 107. When the guide column 107 moves to a specified position, the step feeding limiting block device 205 will clamp the hinge plate, and the step feeding cylinder 204 will drive the hinge plate to move in the conveying belt. The step feeding limiting block device 205 can be arranged in multiple numbers, so that multiple hinge plates can be simultaneously conveyed to different workstations.

The plastic sleeve positioning cylinder 305 is arranged on the other side opposite to the conveying belt 201, and is used to realize the assembly of the plastic sleeve and the hinge plate. In addition, the pushing unit further comprises a long punch 304. After the plastic sleeve is fed into the plastic sleeve feeding groove 206 of the plastic sleeve feeding workstation two 301, the long punch 304 is used to push the plastic sleeve into the hole of the hinge plate of type 79. Because the stroke is long, the long punch 304 is used.

The discharging unit comprises a hinge plate pushing-out station cylinder 503, a rotating cylinder station five 502 and a hinge plate pushing-out station six 501. When the hinge plate is assembled and determined as a qualified product, the hinge plate is transported to the rotating cylinder station five 502, the hinge plate is rotated by 180 degrees (the hinge plate is turned around) or not rotated by the station five 502, and the function is to set the automatic boxing arrangement of the hinge plate grabbed by the mechanical hand; the sixth station functions to push the qualified hinge plate out of the station into the boxing process. After 10 hinge plates on both sides of the qualified hinge plate are added up, the hinge plates are pushed into a position below the mechanical hand, and the hinge plates are automatically loaded into the wooden box. The rotating cylinder station five 502 is provided with a rotating block. The rotating block can be provided with a structure with a channel in the middle. The channel is used for placing the hinge plate. The rotating block can be rotated when the hinge plate needs to be rotated. When the hinge plate does not need to be rotated by 180 degrees, the rotating block does not rotate. Here, the hinge plate boxing condition and quantity are mainly based on. According to actual needs, setting can be carried out.

[0049] The detection process of the hinge plate assembly detection device is as follows:

[0050] The application relates to an automatic detection device for unqualified 79-type hinge plate plastic bushings, which is controlled by a numerical control PLC controller, numerical control servo and frequency converter control, a touch screen and various signal sensors to form a control system, and the 79-type hinge plate adopts a 6-station stepping feeding mechanism. When starting operation, a certain number of plastic bushings are put into a vibrator hopper container, then the vibrator automatically arranges the plastic bushings and then enters a vibrating hopper guide rail, and then the plastic bushings are sent into a plastic bushing (plastic sleeve) guide groove (U type). When the plastic bushings are in place and sensed by an optical fiber switch, a feeding double-shaft air cylinder is driven to push the plastic bushings into the plastic sleeve feeding groove. When the conveying belt sends the hinge plate which is not pressed into the plastic sleeve to the feeding air cylinder, the feeding air cylinder pushes the hinge plate into the feeding station one. When the hinge plate approaches a switch to confirm that the hinge plate reaches the feeding station one, a lifting three-shaft air cylinder is driven to lower the stepping feeding device. The stepping feeding air cylinder device is composed of a linear guide rail sliding table feeding block and a limiting block. After the hinge plate is fed by a certain stepping distance, a second-station opposite positioning punch head precisely positions the hinge plate hole, and then a positioning punch-in-place sensor sends a signal. After the second-station long punch air cylinder drives the plastic bushings in the plastic sleeve feeding groove to push the plastic bushings into the three-quarter hinge plate hole and then retreats to the original position, the feeding double-shaft air cylinder feeds the plastic bushings into the plastic sleeve feeding groove again. Meanwhile, the lifting air cylinder is raised to drive the stepping feeding device to rise to the upper dead point, and then the stepping feeding air cylinder retreats to the original position. When the feeding station one is fed again, the lifting air cylinder is lowered and the stepping feeding air cylinder sends the hinge plate to the third station again, and then the plastic sleeve is pushed into the drawing size requirement. Then the feeding process is repeated again, the fourth station detects the gap between the hinge plate hole and the plastic sleeve by a detection air cylinder, the detection air cylinder drives a detection head to hold a 50-newton quantitative thrust, and when the plastic sleeve is loose and has a displacement distance, the detection air cylinder sends a signal to an unqualified product pushing air cylinder. When the lifting air cylinder rises to the upper dead point, the unqualified product pushing air cylinder drives the unqualified hinge plate to push out of the fourth station and displays the number of unqualified products on the touch screen. The fifth station is a 180-degree rotating air cylinder, which is arranged for the three-shaft servo control mechanical hand to arrange the finished hinge plates in the loading wooden box in a neat manner. The sixth station is a finished product pushing air cylinder which pushes the finished hinge plates out of the station into a loading groove. When a certain number of finished hinge plates are loaded, a servo mechanical hand is used to automatically load the finished hinge plates.

[0051] The device has the advantages that after improvement, the production efficiency and product quality are greatly improved, especially the product quality is detected for each hinge plate, so that the yield of the product is greatly improved, customer complaints are reduced, and the labor intensity of the operator is reduced. In addition, the structure of the feeding device can further save space and improve the hinge plate loading efficiency.
