Controller (not shown in the figure) is also included, and contact sensor 284, horizontal cylinder 281, transverse driving assembly 25, vertical driving assembly 27 are electrically connected with the controller.

[0026] Here, the first gripping mechanism 21 is taken as an example. When the basket 9 with the parts not immersed in oil needs to be conveyed, the horizontal driving assembly 25 of the first gripping mechanism 21 drives the mounting frame 28 to move above the basket 9, the two horizontal cylinders 281 drive the two clamping plates 282 to move outward, and the vertical driving assembly 27 drives the mounting frame 28 to descend. During the descending process, when the contact sensor 284 contacts the upper edge of the upper frame 901 of the basket 9, the contact sensor 284 sends a signal, and after the controller receives the signal, the vertical driving assembly 27 is controlled to stop, and the two horizontal cylinders 281 are controlled to drive the two clamping plates 282 to move inward, so that the hooks 283 on the clamping plates 282 hook the lower edge of the upper frame 901 of the basket 9. Subsequently, the vertical driving assembly 27 drives the mounting frame to rise, thereby taking the basket 9 upward.

[0027] In combination Figure 3 In this embodiment, the horizontal driving assembly 25 includes a horizontal driving motor 251 mounted on the sliding seat 24 and a horizontal rack 252 mounted on the horizontal guide rail 23. A first gear meshing with the horizontal rack 252 is mounted on the output shaft of the horizontal driving motor 251. The vertical driving assembly 27 includes a vertical driving motor 271 mounted on the sliding seat 24 and a vertical rack 272 mounted on the vertical guide rail 26. A second gear meshing with the vertical rack 272 is mounted on the output shaft of the vertical driving motor 271.

[0028] As Figure 1 shown, the oil immersion device 30 includes an oil immersion tank 31 for storing oil and an oil storage tank 32 located on one side of the oil immersion tank 31. The oil immersion tank 31 is connected with the oil storage tank 32 through a first oil pipe 33, and a oil supplementing pump 34 is connected on the first oil pipe 33. A liquid level sensor is arranged in the oil immersion tank 31, which is electrically connected with the controller. In this way, the liquid level of the oil in the oil immersion tank is continuously monitored by the liquid level sensor. As the oil is continuously consumed, when the liquid level sensor detects that the oil in the oil immersion tank needs to be replenished, the liquid level sensor sends a signal, and after the controller receives the signal, the oil supplementing pump 34 is controlled to start, so that the oil in the oil storage tank 32 is supplemented to the oil immersion tank along the first oil pipe 33.

[0029] As Figure 2 and Figure 5As shown, the blow-drying device 40 comprises a housing 41 located in front of the oil tank, a conveying mechanism 42 provided at the bottom of the housing 41, and a wind knife 43 provided in the housing 41 above the conveying mechanism 42. A fan 44 is connected to one side of the wind knife 43. The wind knife 43 has an air outlet 431 facing downwardly to the conveying mechanism. The top of the housing 41 has an inlet 411 at the rear end and an outlet 412 at the front end. A shutter 45 is provided at the inlet and the outlet in the housing 41 for opening or closing the inlet 411 and the outlet 412. Two shutter cylinders 46 are installed in the housing 41, and the two shutters 45 are respectively installed on the piston rod ends of the corresponding shutter cylinders 46, so that the opening or closing of the inlet 411 or the outlet 412 is controlled by driving the horizontal movement of the shutter 45 by the shutter cylinder 46. When the two shutters 45 are closed, a sealed space is formed in the housing 41. A basket detection sensor is provided beside the inlet 411. A stop plate 47 and a position sensor 48 are provided at the front end of the conveying mechanism 42. The two shutter cylinders 46, the basket detection sensor, and the position sensor 48 are electrically connected to the controller.

[0030] In this way, when the first grabbing mechanism 21 delivers the basket 9 above the inlet 411, the basket detection sensor detects the basket and sends a signal, and the controller receives the signal and controls the inlet shutter cylinder 46 to drive the corresponding shutter 45 to move, thereby opening the inlet 411. The vertical driving assembly 27 drives the mounting frame to descend, and the basket 9 enters the housing from the inlet 411 and is placed on the conveying mechanism, and at the same time, the two horizontal cylinders 281 drive the two clamping plates to move outward to loosen the basket 9. Subsequently, the horizontal driving assembly 25 and the vertical driving assembly 27 cooperate to drive the mounting frame 28 to return to the initial position, and the inlet shutter cylinder 46 drives the corresponding shutter 45 to move to close the inlet 411. The conveying mechanism moves the basket to the outlet 412, and in the process of moving, the strong wind blown by the wind knife above the conveying mechanism blows away the oil on the surface of the part, thereby accelerating the draining of the part, reducing the production time, and further reducing the cost. Moreover, the closure of the two shutters forms a sealed space in the housing, which can prevent the oil from being blown away by the strong wind and avoid polluting the air and environment of the production workshop. When the position sensor 48 detects the basket and sends a signal, the controller receives the signal and controls the shutter 45 at the outlet 412 to open, and the second grabbing mechanism delivers the basket to the next process.

[0031] In this embodiment, the number of wind knives 43 is four, and the four wind knives are arranged at intervals above the conveying mechanism.

[0032] In this embodiment, the conveying mechanism 42 is a roller bed driven by a motor. The roller bed comprises a plurality of rollers 421 arranged at intervals in the direction of advancement of the part.

[0033] As Figure 5As shown in the embodiment, an oil receiving tray 35 is arranged below the conveying mechanism 42. The oil receiving tray 35 is connected with the oil tank 31 through a second oil pipe 36, and a filter 37 is connected on the second oil pipe 36. With the structure, the oil blown away from the parts in the casing is collected by the oil receiving tray, and can be recycled, thereby saving the oil. In addition, the impurities in the recycled oil are filtered by the filter 37, thereby improving the quality of the oil.

With the structure, the oil blown away from the parts in the casing is collected by the oil receiving tray, and can be recycled, thereby saving the oil. In addition, the impurities in the recycled oil are filtered by the filter 37, thereby improving the quality of the oil. Figure 1 Figure 4 As shown in the embodiment, an oil receiving tray 35 is arranged below the conveying mechanism 42. The oil receiving tray 35 is connected with the oil tank 31 through a second oil pipe 36, and a filter 37 is connected on the second oil pipe 36.

In addition, the impurities in the recycled oil are filtered by the filter 37, thereby improving the quality of the oil.

[0035] The above is a part of the present application, and its working mode is as follows:

[0036] First, the un-dipped parts 8 are placed in the basket 9, and the basket 9 is placed below the first grabbing mechanism 21. Then, the two horizontal cylinders 281 of the first grabbing mechanism 21 drive the two clamping plates 282 to move outward, and at the same time, the vertical driving assembly 27 drives the mounting frame 28 to descend. During the descending process, when the contact sensor 284 contacts the upper edge of the upper frame 901 of the basket 9, the contact sensor 284 sends a signal, and after the controller receives the signal, the vertical driving assembly 27 stops, and the two horizontal cylinders 281 drive the two clamping plates to move inward, so that the hook 283 on the clamping plate 282 hooks the lower edge of the upper frame 901 of the basket 9. Then, the vertical driving assembly 27 drives the mounting frame to rise, thereby taking the basket 9 up. Then, the horizontal driving assembly 25 drives the mounting frame 28 to move above the oil tank 31. Then, the vertical driving assembly 27 drives the mounting frame to descend, taking the basket 9 down into the oil tank 31 for oil dipping process.

[0037] ​When the oil immersion ends and the parts need to be dried, the first grabbing mechanism 21 delivers the basket 9 to above the inlet 411. After the basket detection sensor detects the basket 9, a signal is sent, and the controller receives the signal, controls the inlet gate cylinder 46 to drive the corresponding gate 45 to move, and opens the inlet 411. At the same time, the air blower is controlled to start, so that when the inlet gate or the outlet gate is opened, the exhaust gas enters the filter 54 through the air pipe 53 from the suction nozzle 51 under the negative pressure generated by the air blower 52, and the oil in the exhaust gas is intercepted by the filter bag of the filter 54, and the clean air is directly discharged into the atmosphere, so as to avoid the pollution of the workshop environment. The vertical driving assembly 27 drives the mounting frame 28 to descend, and the basket 9 is placed on the conveying mechanism in the shell from the inlet 411, and at the same time, the two horizontal cylinders 281 drive the two clamping plates to move outward to loosen the basket 9. Then, the horizontal driving assembly 25 and the vertical driving assembly 27 are cooperated to drive the mounting frame 28 to return to the initial position, and wait for the next basket 9 to be delivered. The inlet gate cylinder 46 drives the corresponding gate 45 to move, and closes the inlet 411, and a closed space is formed in the shell. The conveying mechanism moves the basket 9 to the outlet 412, and in the moving process, the strong wind blown by the air knife above the conveying mechanism blows away the oil on the surface of the parts, so as to accelerate the draining of the parts.

[0038] When the basket detection sensor 48 detects the basket and sends a signal, the controller receives the signal, controls the outlet 412 gate 45 to open, and controls the two horizontal cylinders 281 of the second grabbing mechanism 22 to drive the two clamping plates 282 to move outward, and at the same time, the vertical driving assembly 27 drives the mounting frame 28 to descend into the shell from the outlet 412. In the descending process, when the contact sensor 284 contacts the upper edge of the upper frame 901 of the basket 9, the contact sensor 284 sends a signal, and the controller receives the signal, controls the vertical driving assembly 27 to stop, and controls the two horizontal cylinders 281 to drive the two clamping plates to move inward, so that the hook 283 on the clamping plate 282 hooks the lower edge of the upper frame 901 of the basket 9. Then, the vertical driving assembly 27 drives the mounting frame to rise, so as to carry the basket 9 to rise, and the outlet gate cylinder 46 drives the corresponding gate 45 to move, and closes the inlet 411. Then, the horizontal driving assembly 25, the vertical driving assembly 27 and the horizontal cylinder of the second grabbing mechanism 22 are cooperated to deliver the basket to the next process.

[0039] The above describes one embodiment of the utility model in detail, but the content described is only the preferred embodiment of the utility model, and cannot be considered as limiting the implementation range of the utility model. Any equivalent change and improvement within the scope of the utility model application should still belong to the patent coverage range of the utility model.
