Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0033] Reference Figure 1 and Figure 2 An example of the utility model provides a jig cover plate picking and placing mechanism, which is arranged on a cleaning machine body, and includes a cover plate storage bin 1, a bracket 2, a moving device arranged on the bracket 2, and a manipulator 3 arranged on the moving device.

[0034] The cover plate storage bin 1 is used to store the fixture cover plates.

[0035] Structurally, the moving device includes a longitudinal moving component 4 and a lifting component 5. The longitudinal moving component 4 is used to drive the manipulator 3 to move horizontally along a conveying direction perpendicular to the base, and the lifting component 5 is used to drive the manipulator 3 to move up and down.

[0036] In terms of position, the longitudinal moving component 4 is arranged on the bracket 2 , the lifting component 5 is arranged on the longitudinal moving component 4 , and the manipulator 3 is arranged on the lifting component 5 .

[0037] It should be noted that the positions of the lifting assembly 5 and the longitudinal moving assembly 4 can be interchanged.

[0038] Specifically, the manipulator 3 includes a connecting arm 31 and a grabbing assembly 32 arranged at one end of the connecting arm 31 , and the other end of the connecting arm 31 is arranged on the lifting assembly 5 , and the grabbing assembly 32 is used to grab the jig cover stored on the cover storage bin 1 .

[0039] When the conveying mechanism of the cleaning machine conveys the base to the set position, the longitudinal moving component 4 drives the lifting component 5 and the manipulator 3 to move to just above the cover storage bin 1. Then, the lifting component 5 drives the manipulator 3 to descend, and the grabbing component 32 in the manipulator 3 grabs the jig cover stored on the cover storage bin 1. Then, the lifting component 5 drives the manipulator 3 to rise, and the longitudinal moving component 4 drives the lifting component 5 and the manipulator 3 to move to the top of the conveying mechanism, and aligns the jig cover on the manipulator 3 with the base on the conveying mechanism. Then, the lifting component 5 drives the manipulator 3 to descend, and the grabbing component 32 in the manipulator 3 places the jig cover on the base. Finally, the lifting component 5 drives the manipulator 3 to rise, and the longitudinal moving component 4 drives the lifting component 5 and the manipulator 3 to move to the original position. Thereby, the jig cover on the cover storage bin 1 can be automatically taken and placed on the base, thereby reducing the labor intensity of workers and improving production efficiency.

[0040] Reference Figure 2 and Figure 3 In some preferred embodiments, the grabbing assembly 32 includes a connecting plate 321, a first driving member 322 arranged on the connecting plate 321, and a clamping claw 323 arranged at the output end of the first driving member 322. The first driving member 322 is used to drive the clamping claw 323 to clamp or release the jig cover, thereby improving the stability of the grabbing action.

[0041] Specifically, the clamping jaw 323 includes a first clamping finger and a second clamping finger. The first driving member 322 drives the first clamping finger to approach or move away from the second clamping finger so that the clamping jaw 323 clamps or releases the fixture cover.

[0042] Furthermore, two first clamping fingers and two second clamping fingers are provided, and the two first clamping fingers and the two second clamping fingers are connected together by a clamping claw connecting block. The two clamping claw connecting blocks are provided at the output end of the first driving member 322. The first driving member 322 is used to drive the two clamping claw connecting blocks to move closer to or away from each other, thereby making the two first clamping fingers and the two second clamping fingers clamp or release the two sides of the jig cover plate, thereby increasing the force points of the jig cover plate, making the jig cover plate evenly stressed, preventing the jig cover plate from being skewed during transfer, and improving the accuracy of picking and placing the jig cover plate.

[0043] Furthermore, the connecting plate 321 is also provided with a protective shell, and the first driving member 322 is located in the protective shell.

[0044] Furthermore, a first photoelectric sensor 324 is disposed on one side of the connecting plate 321 , and the first photoelectric sensor 324 is used to detect whether the clamping claw 323 clamps the fixture cover.

[0045] Specifically, when the first photoelectric sensor 324 detects that the clamping claw 323 has not clamped the fixture cover, the device will issue an abnormal alarm and stop running.

[0046] Reference Figure 2 and Figure 4 In some preferred embodiments, the longitudinal moving component 4 includes a first slide rail 41, a first slide seat 42 and a second driving member 43. The first slide seat 42 is slidably connected to the first slide rail 41. The second driving member 43 is used to drive the first slide seat 42 to move along the length direction of the first slide rail 41. The lifting component 5 is installed on the first slide seat 42 through the base 44, so that the guidance of the lifting component 5 and the manipulator 3 can be ensured when moving together, thereby improving the movement accuracy of the manipulator 3.

[0047] Furthermore, a photoelectric sensing switch 45 is provided on one side of the first slide rail 41, and a photoelectric sensing sheet 46 is provided on one side of the first slide seat 42. At least two photoelectric sensing switches 45 are provided, and the two photoelectric sensing switches 45 are located directly above the conveying mechanism and the cover storage bin 1. When the second driving member 43 drives the first slide seat 42 to move to directly above the conveying mechanism or the cover storage bin 1, the photoelectric sensing sheet 46 provided on one side of the first slide seat 42 corresponds to the photoelectric sensing switch 45, and the photoelectric sensing switch 45 transmits a signal to the second driving member 43 to stop the second driving member 43 from running, thereby ensuring the accurate positioning of the lifting assembly 5 and the manipulator 3.

[0048] Furthermore, the lifting assembly 5 includes a second slide rail 51, a second slide seat 52 and a third driving member 53. The second slide seat 52 is slidably connected to the second slide rail 51. The third driving member 53 is used to drive the second slide seat 52 to move along the length direction of the second slide rail 51. The second slide rail 51 is vertically arranged, one end of the second slide rail 51 is fixed on the base 44, and one end of the connecting arm 31 is fixed on the second slide seat 52, thereby ensuring that the manipulator 3 can move in the vertical direction and improving the movement accuracy of the manipulator 3.

[0049] Reference Figure 2 , Figure 5 and Figure 6 In some preferred embodiments, the cover storage bin 1 includes a bin connecting frame 11, a bottom plate 12 arranged on the bin connecting frame 11, and a plurality of limiting columns 13 arranged on the bottom plate 12. The bin connecting frame 11 is fixedly connected to the conveying mechanism of the cleaning machine, and the plurality of limiting columns 13 are vertically arranged. The jig cover is stacked on the bottom plate 12. The plurality of limiting columns 13 are used to limit the four sides of the jig cover. There is a certain distance between adjacent limiting columns 13 to form an avoidance position, so that the clamping claw 323 can avoid the air and prevent the clamping claw 323 from interfering with the cover storage bin 1 when grabbing the jig cover.

[0050] Furthermore, a photoelectric component 14 is also provided on one side of the base plate 12, and the photoelectric component 14 includes a photoelectric mounting board 141, and a plurality of second photoelectric sensors 142 mounted on the photoelectric mounting board 141 from bottom to top. The plurality of second photoelectric sensors 142 correspond one by one to a plurality of jig cover plates, respectively, and the second photoelectric sensors 142 are used to detect whether the jig cover plate is grasped.

[0051] When the second photoelectric sensor 142 detects that the fixture cover on the cover storage bin 1 is grabbed, the second photoelectric sensor 142 transmits a signal to the lifting component 5, and the lifting component 5 drives the manipulator 3 to move upward.

[0052] At the same time, a plurality of second photoelectric sensors 142 can also detect the number of fixture covers stored in the cover storage bin 1 for easy counting.

[0053] Specifically, the optoelectronic mounting board 141 is provided with an adjustment groove 1411, which is vertically arranged. A plurality of second photoelectric sensors 142 are installed in the adjustment groove 1411 through a locking member 143. When the thickness of the jig cover changes, the locking member 143 is released, and the plurality of second photoelectric sensors 142 can be moved to corresponding positions along the length direction of the adjustment groove 1411, and then the second photoelectric sensors 142 are locked on the optoelectronic mounting board 141 through the locking member 143, thereby being able to adapt to jig covers of different specifications and improving the flexibility of the equipment.

[0054] Furthermore, the locking member 143 includes two nuts 1431, and a screw 1421 is provided at one end of the second photoelectric sensor 142. The screw 1421 passes through the adjustment slot 1411 and is locked by two nuts 1431, so that the two nuts 1431 are close to both sides of the photoelectric mounting board 141, thereby improving the installation firmness of the second photoelectric sensor 142.

[0055] In order to prevent the second photoelectric sensors 142 from being hit by external force, a shell is provided on one side of the photoelectric mounting board 141 to form an inner cavity between the shell and the photoelectric mounting board 141 . The main bodies of the second photoelectric sensors 142 are located inside the inner cavity, and the sensing ends of the second photoelectric sensors 142 extend out of the photoelectric mounting board 141 .
