During the production and installation process of the electro-hydraulic valve controller, it is necessary to apply glue on the mating surface of the base, manually install the connectors on the base, and then screw them in to fix them. Due to the special structure and high requirements of the electro-hydraulic valve controller, the electro-hydraulic valve controller is prone to damage or improper installation during installation. Therefore, the production and installation of existing electro-hydraulic valve controllers are mainly assembled by manual labor and auxiliary tools. The manual assembly relies entirely on the experience of the personnel to evaluate the pressing pressure and tightening torque. Manual experience is unstable, so the defective rate of the products produced is high, the labor intensity of the personnel during the pressing process is high, and the production capacity is low.

[0024] Preferably, the connector loading station 4, the wiring arrangement and panel installation station 7 are all provided with corresponding manual positions, and the manual positions are located outside the conveyor line 1, and the operations of connector loading, wiring arrangement and panel installation are performed at the manual positions.

[0025] In this embodiment, when processing is performed, the robot 20 places the workpiece base into the sliding assembly 13, and the conveying drive module 14 drives the sliding assembly 13 and the base to slide in the annular guide rail 12, and transports the base to each workstation for processing. At the same time, the auxiliary component 32 operates to cut off the solidified residual glue on the gluing device 30 and prevent the glue from precipitating, and the pressing device 40 and the screwing device 50 are used to install and fix the plug-ins and panels of the workpiece. After the processing is completed, the robot 20 removes the workpiece from the sliding assembly 13.

[0026] Next, please refer to Figures 4 to 5 The sliding assembly 13 includes a slider 132, a roller 131 is hinged at the bottom of the slider 132, the outer edge bottom of the roller 131 is in contact with the annular guide rail 12, a connecting plate 133 is fixedly connected to the slider 132, and a fixing column 134 is fixedly connected to the other end of the connecting plate 133, and the fixing column 134 is fixedly connected to the conveying drive module 14; the frame 11 is fixedly installed with a limiting assembly 135 at the position below each station, and a limiting groove 136 is provided on the side of the slider 132 close to the limiting assembly 135.

The upper end outer ring of the lifting rod 321 is slidably connected to the limiting sleeve 322, and the limiting sleeve 322 is fixedly connected to the bottom of the inner cavity of the glue barrel 303. The outer ring of the limiting sleeve 322 is hinged with four groups of stirring rods 323. The middle section outer ring of the lifting rod 321 is fixedly connected to the driving clamp 324, and the lower end outer ring of the stirring rod 323 is slidably connected in the driving clamp 324. The lower end of the execution end of the second robot arm 301 is fixedly installed with a motor 325, and a cam rod 326 is fixedly connected to the output shaft of the motor 325. The outer ring of the cam rod 326 is movable. Connected to the inner circle of the bottom end of the lifting rod 321, the inner cavity of the cam rod 326 is provided with a hexagonal groove, and a gear rod 327 is slidably connected in the groove, the lower end of the execution end of the robot arm 2 301 is fixedly installed with an electric push rod 328, the output end of the electric push rod 328 is fixedly connected to a moving frame 329, the gear rod 327 is rotatably connected in the moving frame 329 through a ball bearing, the lower end of the execution end of the robot arm 2 301 is rotatably connected to a bevel gear 3210 through a ball bearing, the lower end of the bevel gear 3210 passes through the execution end of the robot arm 2 301 and is fixedly connected with a cutting knife 3211, the cutting knife 3211 is contacted and connected to the lower end of the nozzle 302, and the lower end of the execution end of the robot arm 2 301 is fixedly connected with a scratch clamp 3212.

[0030] It should be noted that the portion of the gear rod 327 that extends into the inner cavity of the cam rod 326 is a hexagonal rod, so that the gear rod 327 can both slide in the cam rod 326 and be driven to rotate by the cam rod 326; The gear on the gear rod 327 and the bevel gear 3210 can mesh with each other, so that when the gear rod 327 contacts the bevel gear 3210, the gear rod 327 can rotate with the driving bevel gear 3210; The top of the lifting rod 321 is provided with a raised limiting component, and the lower end is provided with a long strip frame, and the limiting part is slidably connected to the upper end of the limiting sleeve 322, and the long strip frame is provided on the outer side of the cam rod 326, so that the cam rod 326 can push the long strip frame and the lifting rod 321 to move up and down by rotating, and the movable range of the lifting rod 321 is limited by the limiting component, so that it cannot rotate, avoiding affecting the contact with the cam rod 326; A round rod is provided at one end of the stirring rod 323 close to the inner cavity of the limiting sleeve 322, and the round rod is slidably connected in the driving clamp 324, so as to utilize the up and down reciprocating movement of the driving clamp 324 to drive the stirring rod 323 to reciprocate up and down to avoid the glue in the glue barrel 303 from settling.

[0031] In this embodiment, when in use, the glue pump 304 draws glue from the glue barrel 303 and sprays it on the base of the workpiece through the nozzle 302 to wait for processing. At this time, the motor 325 drives the cam rod 326 to rotate, driving the lifting rod 321 to move up and down, and uses the driving clamp 324 to drive the stirring rod 323 to rotate back and forth up and down, stirring the glue in the glue barrel 303 to prevent the glue inside from settling. If the glue on the nozzle 302 solidifies due to long-term contact with air, the electric push rod 328 will run and shrink, pulling the movable frame 329 to move, so that the gear rod 327 is engaged with the bevel gear 3210. At this time, the cam rod 326 will drive the gear rod 327 and the bevel gear 3210 to rotate together, thereby rotating the cutting knife 3211 to cut off the solidified glue on the nozzle 302. Then the nozzle 302 will enter the scratch clamp 3212.

[0039] Example 2 Please refer again Figure 16 to Figure 17 , which is the second embodiment of the present invention, and provides a production process of an electro-hydraulic valve controller, which is applicable to the production line of the electro-hydraulic valve controller to produce the electro-hydraulic valve controller, and includes: S1: loading the base, i.e., using the loading and unloading manipulator 20 to automatically load the base of the electro-hydraulic valve controller onto the placement seat 15 on the conveyor line 1, driving the base to rotate clockwise; S2: Entering the gluing hole on the base and applying glue, that is, when the placement seat 15 carrying the base moves to the gluing station 3, the gluing device 30 applies glue to the gluing hole on the base passing through the gluing station 3; S3: a connector pre-installation process, i.e., when the placement seat 15 moves to the connector placement station, the connector is pre-installed on the base manually; a connector and base pressing process, i.e., adjusting the parameters of the pressing device according to the requirements of the electro-hydraulic valve controller to press the connector on the base; S4: a pressing process of the connector and the base, that is, adjusting the parameters of the pressing device according to the requirements of the electro-hydraulic valve controller to press the connector onto the base; S5: Entering the screw tightening process between the connector and the base, that is, the screwing device 50 tightens the connector and the base by screws; S6: When the corresponding placement seat 15 moves to the line row and panel installation station, the line row and panel are installed manually; S7: panel screw tightening process, that is, the screwing device 50 tightens the panel and the connector by screws; S8: Automatic unloading, that is, using the unloading and unloading robot 20 to automatically unload the installed electro-hydraulic valve controller on the finished product unloading station 9 onto the finished product tray 70.

[0040] In this embodiment, during the gluing process in S2, the pressing process of the connector and the base in S4, the screw fastening process between the connector and the base in S5, and the panel screw fastening process in S7, the conveyor line 1 stops conveying; The gluing process in S2, the pressing process of the connector and the base in S4, the screw tightening process between the connector and the base, and the panel screw tightening process are carried out simultaneously during the stop time of the conveyor line 1.

[0041] The working principle of the present invention is as follows: the robot arm 201 controls the clamping claw 203 to clamp the workpiece base and place it in the placement seat 15, and then the conveying drive module 14 drives the slider 132 to slide in the annular guide rail 12, and when it moves to the designated station, the limit assembly 135 moves up and is fixed in the limit groove 136. At this time, the glue pump 304 extracts glue from the glue barrel 303, sprays it on the base of the workpiece through the nozzle 302 and waits for processing. At the same time, the motor 325 drives the cam rod 326 to rotate, driving the lifting rod 321 to move up and down, and uses the driving clamp 324 to drive the stirring rod 323 to rotate back and forth up and down, stirring the glue in the glue barrel 303 to prevent the glue inside from settling. Then the placement seat 15 will move to the connector on-line station 4, where the plug-in is placed manually, and then move to the pressing station 5. At this time, the hydraulic cylinder 403 pushes the upper die 407 down to squeeze and fix the workpiece and the plug-in, and then enters the screwing station 1 6 to fix the plug-in, and then enters the wiring and panel installation station 7 to manually place the panel and arrange the wiring, and then enters the screwing station 2 8 to fix the panel, and finally moves to the finished product off-line station 9, where the robot 20 takes out the finished workpiece and places it on the finished product tray 70 to complete the processing.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
