DETAILED DESCRIPTION
[0027] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.
[0028] The embodiment of the present application provides an automatic cleaning machine, such as Figure 1 As shown, the automatic cleaning machine is used to automatically clean workpieces. The automatic cleaning machine 100 includes a frame 10 and a transfer mechanism 20 and a protective device 30 mounted on the frame 10. The transfer mechanism 20 and the protective device 30 are mounted on the top of the frame 10, and the frame 10 supports the transfer mechanism 20 on the ground.
[0029] like Figure 1-4 As shown, the frame 10 has a center line X1 extending in the up-down direction, and the frame 10 is circumferentially arranged with a plurality of workstations 40, all of which are processing stations for surface treatment of workpieces. The processing station can be a single cleaning station, and multiple cleaning stations clean multiple workpieces at the same time to improve cleaning efficiency; the multiple processing stations can also be stations for different surface treatment processes, and the workpieces enter the multiple processing stations in sequence to perform multiple surface treatment processes. In the embodiment of the present application, each station 40 is equipped with a cleaning tank 1, and the cleaning tank 1 contains a cleaning liquid, and the workpiece surface is cleaned by immersing the workpiece in the cleaning liquid. A support frame 2 is arranged around the frame 10, and the cleaning tanks 1 of the multiple workstations 40 are sequentially installed on the top of the support frame 2 along the circumference of the center line X1.
[0030] The transfer mechanism 20 includes a transfer bracket 3 that can rotate around the center line X1 and can be lifted and lowered along the center line X1, a plurality of hanging baskets 4 sequentially suspended along the circumference of the transfer bracket 3, and a driving device 5 for driving the transfer bracket 3 to rotate and lift. Figure 6 、 7 As shown, the driving device 5 includes a lifting cylinder 51 and a rotating motor 52. The rotating motor 52 is connected to the transfer bracket 3 and drives the transfer bracket 3 to rotate around the center line X1, so that the transfer bracket 3 drives multiple hanging baskets 4 to move on multiple workstations 40 until they move directly above the desired workstation 40. The lifting cylinder 51 is installed between the frame 10 and the transfer bracket 3 and is used to push the transfer bracket 3 to move back and forth along the center line X1 relative to the frame 10. During the lifting process of the transfer bracket 3, the multiple hanging baskets 4 are respectively located in a first position directly above a workstation 40 and each hanging basket 4 enters a second position corresponding to the workstation 40, with the first position being above the second position. The hanging basket 4 is used to load the workpiece. When the transfer bracket 3 is in the second position, the hanging basket 4 enters the corresponding workstation 40. The workpiece in the hanging basket 4 is immersed in the cleaning tank 1 of the corresponding workstation 40, and the surface of the workpiece is cleaned by the cleaning liquid in the cleaning tank 1.
[0031] like Figure 1 As shown, a protective device 30 is also installed on the top of the frame 10. When the hanging basket 4 on the transfer bracket 3 is not aligned with the lower cleaning tank 1, the protective device 30 is located below the transfer bracket 3 to prevent the transfer bracket 3 from suddenly falling due to operating errors or sudden power failure, effectively protecting the workpiece, the automatic cleaning machine 100 and the surrounding operators. Figure 8 As shown, during the rotation of the transfer bracket 3, when each hanging basket 4 deviates from the top of each work station 40, the protection device 30 is located in the downward movement path of the transfer bracket 3, blocking the downward trend of the transfer bracket 3 below the transfer bracket 3; Figure 4 As shown, when the transfer bracket 3 rotates to the first position, each hanging basket 4 is located directly above a work station 40, and the protective device 30 is located outside the moving path of the transfer bracket 3. The mobile bracket 3 can be raised and lowered freely, and each hanging basket 4 can accurately enter the cleaning tank 1 of the corresponding work station 40.
[0032] Continue to refer to the attached Figure 1 In the embodiment of the present application, the transfer bracket 3 includes a connecting portion 31 and a plurality of support arms 32 sequentially arranged along the circumference of the connecting portion 31. The connecting portion 31 is in driving connection with the driving device 5, and each support arm 32 extends radially outward from the connecting portion 31. Each support arm 32 has an inner end 321 connected to the connecting portion 31 and an outer end 322 away from the connecting portion 31. A hanging bracket 33 is mounted on the outer end 322. The hanging basket 4 is detachably mounted on the hanging bracket 33, facilitating the movement of the hanging basket 4 loaded with workpieces into and out of the transfer mechanism 20.
[0033] like Figure 1 、 4 As shown in Figures 5, 8, and 9, the protective device 30 includes a pair of anti-fall blocks 6 installed on the top of the frame 10, and the pair of anti-fall blocks 6 are relatively arranged with the center line X1 as the center, and the projection of each anti-fall block 6 from top to bottom is fan-shaped. When the transfer bracket 3 is in the first position, each anti-fall block 6 is located between two adjacent support arms 32, and the projection of the transfer bracket 3 from top to bottom does not coincide with the projection of the pair of anti-fall blocks 6; when the transfer bracket 3 rotates around the center line X1, each hanging basket 4 offsets directly above each workstation 40, and at least part of the projection of the transfer bracket 3 from top to bottom coincides with at least part of the projection of the pair of anti-fall blocks 6. The pair of anti-fall blocks 6 block the bottom of the transfer bracket 3, preventing the transfer bracket 3 from moving downward at this time, and avoiding the hanging basket 4 from contacting the wall of the cleaning tank 1 during the descent and being overturned, thereby ensuring the stability of the automatic cleaning machine 100 during operation.
[0034] Each anti-fall block 6 includes an inner arc side wall 61 and an outer arc side wall 62 with the center line X1 as the axis line, and a first side wall 63 and a second side wall 64 arranged opposite to each other. The inner arc side wall 61 is located on the inner side of the outer arc side wall 62, the first side wall 63 connects one end of the inner arc side wall 61 and one end of the outer arc side wall 62, and the second side wall 64 connects the other end of the inner arc side wall 61 and the other end of the outer arc side wall 62. The inner arc side wall 61, the outer arc side wall 62, the first side wall 63 and the second side wall 64 form an anti-fall block 6 with a fan-shaped projection, and the angle α between the first side wall 63 and the second side wall 64 is consistent with the angle β between the two adjacent support arms 32.
[0035] like Figure 4 、 5 As shown in Figure 9, the transfer mechanism 20 also includes a positioning component 7, which includes a photoelectric switch 71 and a plurality of triggering members 72 that can trigger the photoelectric switch 71. The photoelectric switch 71 is installed on the top of the frame 10 and is connected to the signal of the rotating motor 52. The plurality of triggering members 72 are installed on the connecting portion 31 of the transfer bracket 3 and are arranged in sequence around the circumference of the center line X1. The number of triggering members 72 is consistent with the number of workstations 40. Each workstation 40 corresponds to a triggering member 72. When the triggering member 72 contacts the photoelectric switch 71 to trigger the photoelectric switch 71, the photoelectric switch 71 transmits a signal to the rotating motor 52 after being triggered, so that the rotating motor 52 stops after the transfer bracket 3 moves to the first position, so as to realize the positioning of the transfer bracket 3 and improve the positioning accuracy. The position of each hanging basket 4 is adjusted to be directly above each workstation 40, so as to facilitate the hanging basket 4 to descend into the cleaning tank 1 of the corresponding workstation 40.
[0036] The automatic cleaning machine 100 also includes a controller (not shown in the figure). The controller is connected to the rotating motor 52, the lifting cylinder 51, and the photoelectric switch 71. The controller receives signals transmitted by the photoelectric switch 71 and controls the operation of the rotating motor 52 and the lifting cylinder 51. Based on the trigger signal transmitted by the photoelectric switch 71, the controller controls the start and stop of the rotating motor 52 and the air inlet and outlet of the lifting cylinder 51, so that the transfer bracket 3 can accurately stop at the first position and switch between the first position and the second position. The controller controls the operation of the rotating motor 52 and, based on the signal transmitted by the photoelectric switch 71, controls each suspended hanging basket 4 to accurately stop directly above a work station 40; and controls the lifting cylinder 51 to push the transfer bracket 3 up and down between the first position and the second position.
[0037] The working process is as follows: the hanging basket 4 loaded with workpieces is hoisted to the hoisting bracket 33 on the transfer bracket 3, the controller controls the rotating motor 52 to work, the transfer bracket 3 rotates around the center line X1, and when the hanging basket 4 moves to directly above a work station 40, the trigger member 72 corresponding to the work station 40 triggers the photoelectric switch 71, and the controller controls the rotating motor 52 to stop rotating. At this time, the transfer bracket 3 is in the first position, and the controller controls the lifting cylinder 51 to work to lower the transfer bracket 3. The transfer bracket 3 drops to the second position. At this time, the hanging basket 4 enters the work station 40 directly below and is immersed in the cleaning tank 1 in the work station 40. The workpiece in the hanging basket 4 is immersed in the cleaning liquid in the cleaning tank 1 for cleaning; the controller controls the lifting cylinder 51 to work to raise the transfer bracket 3 and move it from the second position to the first position. The rotating motor 52 rotates the transfer bracket 3, so that the hanging basket 4 is transferred to the lower part, and the hanging basket 4 loaded with the cleaned workpiece is removed from the transfer bracket 3.
[0038] The multiple workstations on the circumference of the frame of the present application are coordinated with a transfer bracket that can be both rotated and raised to achieve automatic cleaning of one or more workpieces at the same time. The protective device on the automatic cleaning machine is located on the descending path of the transfer bracket in the event of an operating error or sudden power outage of the equipment, preventing the transfer bracket from descending and causing the hanging basket to overturn, thereby improving the stability and safety of the automatic cleaning machine during operation.
[0039] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application.
