Examples: as shown in fig. 1-18, a rotary composite grabbing reaction cup device comprises a rotary support 100, a motor mounting plate 200 is arranged above the rotary support 100, a rotary motor 300 is arranged on the motor mounting plate 200, a spring tray rotating shaft 400 is arranged below the rotary support 100, the spring tray rotating shaft 400 is in power connection with the rotary motor 300, an upper spring tray 500 is arranged at the upper end of the spring tray rotating shaft 400, a lower spring tray 530 is connected to the free end of the spring tray rotating shaft 400 through a bearing 600, five tension springs 540 are arranged between the upper spring tray 500 and the lower spring tray 530, and a reaction cup grabbing mechanism 900 is arranged below the lower spring tray 530.
The upper spring tray 500 is provided with a front oval follower column 510 and a rear oval follower column 520, and the front oval follower column 510 and the rear oval follower column 520 are oppositely arranged.
The rotating motor 300 drives the spring tray rotating shaft 400 to rotate, the spring tray rotating shaft 400 can drive the upper spring tray 500 to rotate, the lower spring tray 530 can also rotate under the action of the tension spring 540, and the lower spring tray 530 can rotate or not rotate due to the limit of the horizontal position limiting device, and the reaction cup grabbing mechanism 900 is arranged below the lower spring tray 530, so that the angle of the reaction cup 1000 can be changed due to the rotation of the lower spring tray 530.
The advantage of using the tension spring 540 in the present invention is that if the lower spring tray 530 and the spring tray rotating shaft 400 are connected by using a rubber brush or a cam gear, when the lower spring tray 530 is limited, the spring tray rotating shaft 400 can also continue to move, but in the present invention, when the left finger 930 and the right finger 940 are opened to the maximum, the left finger 930 and the right finger 940 need to be turned around by the spring tray rotating shaft 400 to close, but in the turning around process, the state of the grabbing reaction cup 1000 is ensured, that is, the left finger 930 and the right finger 940 cannot rotate, the position must be fixed, and if the rubber brush or the cam gear is used for connection, the lower spring tray 530 can also turn around together in the turning around process, but in the turning around process, the tension spring 540 cannot be used; for example, when the spring tension variable is 1mm or less, a pulling force is generated, and when the distance between the two left fingers 930 and the right finger 940 is the maximum, it is assumed that the tension variable of the tension spring 540 is 10mm, and at this time, under the action of the five tension springs 540, the lower spring tray 530 is firmly limited at one side, and when the spring tray rotating shaft 400 rotates by a small angle, the left finger 930 and the right finger 940 can be closed, and when the tension variable of the tension spring 540 is 9mm, the lower spring tray 530 is still limited at one side, and at this time, the left finger 930 and the right finger 940 cannot rotate, but can be smoothly closed to grasp the reaction cup 1000.
The reaction cup grabbing mechanism 900 includes a wire rail support 910 disposed below the lower spring tray 530, a wire rail 920 is disposed on the wire rail support 910, a left slider 921 and a right slider 922 are disposed on the wire rail 920, a left slider baffle 923 and a right slider baffle 924 are disposed at two ends of the wire rail 920, the left slider baffle 923 and the right slider baffle 924 are disposed to limit the left slider 921 and the right slider 922, firstly, the left slider 921 and the right slider 922 are prevented from being separated from the wire rail 920, secondly, the front oval follower column 510 and the rear oval follower column 520 are guaranteed to be tangent to the left finger moving cam follower 960 and the right finger moving cam follower 980 on the left side and the right side to be the radial maximum positions, and if the rotating motor 300 is out of control or is not operated properly, the positions of the front oval follower column 510 and the rear oval follower column 520 are also guaranteed, the position rotation transition is not generated, and the phenomenon that cannot reset is caused.
A left finger fixing block 925 is arranged on the left slider 921, a right finger fixing block 926 is arranged on the right slider 922, a left return spring 927 is arranged between the wire rail support 910 and the left finger fixing block 925, a right return spring 928 is arranged between the wire rail support 910 and the right finger fixing block 926, a left finger 930 is arranged on the left finger fixing block 925, and a right finger 940 is arranged on the right finger fixing block 926; the left and right return springs 927 and 928 are arranged to allow the left and right finger blocks 925 and 926 to return closed without a pushing force. The left finger fixing block 925 is provided with a left positioning pin 950 and a left finger moving cam follower 960, and the right finger fixing block 926 is provided with a right positioning pin 970 and a right finger moving cam follower 980.
The invention further comprises a horizontal position limiting device 700 and a vertical position limiting device 800, wherein the horizontal position limiting device 700 comprises a first mounting bracket 710 which extends downwards on the rotating bracket 100, a horizontal position blocking cam bearing follower 720 and a horizontal position photoelectric switch 730 are arranged on the first mounting bracket 710, and a horizontal position photoelectric baffle 740 is arranged on the left finger fixing block 925; the vertical position limiting device 800 includes a second mounting bracket 810 extending downward on the rotating bracket 100, a vertical position blocking cam bearing follower 820 and a vertical position photoelectric switch 830 are disposed on the second mounting bracket 810, and a vertical position photoelectric blocking piece 840 is disposed on the right finger fixing block 926. The horizontal position limiting device 700 uses the left positioning pin 950 and the horizontal position blocking cam bearing follower 720 to limit, the vertical position limiting device 800 uses the right positioning pin 970 and the vertical position blocking cam bearing follower 820 to limit, and because the left finger 930 and the right finger 940 need to be opened and closed in a series of movements while limiting, the traditional limiting mode, the opening and closing of the finger can be carried out by a great friction force, so that inaccuracy is caused, and the cam follower is adopted, because of the unique property, no static friction force (the friction force is converted from static friction to rolling friction) is generated, so that the opening and closing of the finger are smoother.
When the upper spring tray 500 rotates clockwise, the front oval follower post 510 is tangent to the left finger moving cam follower 960 and pushes the left finger moving cam follower 960 to move leftwards, the left finger moving cam follower 960 drives the left finger fixing block 925 to move leftwards, so as to drive the left finger 930 to move leftwards, the rear oval follower post 520 is tangent to the right finger moving cam follower 980 and pushes the right finger moving cam follower 980 to move rightwards, and the right finger moving cam follower 980 drives the right finger fixing block 926 to move rightwards, so that the right finger 940 is driven to move rightwards, and the reaction cup grabbing mechanism 900 is opened to grab the reaction cup 1000.
The rotary support 100 is further provided with a motor horizontal position resetting photoelectric switch 110 and a motor vertical position resetting photoelectric switch 120, the motor horizontal position resetting photoelectric switch 110 and the motor vertical position resetting photoelectric switch 120 are arranged at 90 degrees, a quarter round motor rotary photoelectric baffle 130 is arranged above the rotary motor 300, a reaction cup is arranged on a left finger fixing block 925 and provided with a no-light photoelectric switch 140, a reaction cup is arranged on a right finger fixing block 926 and provided with a no-light photoelectric baffle 150, a clamping jaw opening photoelectric baffle 160 is arranged on the left finger fixing block 925, and a clamping jaw opening photoelectric switch 170 is arranged on the right finger fixing block 926; the arrangement can enable the operation precision of the device to be higher.
The working principle of the invention is as follows:
The present invention provides that when the horizontal position photoelectric blocking piece 740 blocks the horizontal position photoelectric switch 730 to be the initial position for grabbing the reaction cup 1000, at this time, the default initialization direction rotates to the left after the rotating motor 300 is powered on, so as to drive the spring tray rotating shaft 400 and the motor rotating photoelectric blocking piece 130 to rotate together, and the lower spring tray 530 rotates along with the spring tray rotating shaft 400 under the action of the five tension springs 540.
When the left positioning pin 950 contacts the horizontal position blocking cam bearing follower 720, the horizontal position photoelectric switch 730 is blocked by the horizontal position photoelectric blocking piece 740; at this time, the lower spring tray 530 and the spring tray rotating shaft 400 do not have corresponding rotational displacement yet, and the horizontal position photoelectric switch 730 is completely blocked by the horizontal position photoelectric blocking piece 740, but in order to ensure the reliability of the position when the reaction cup 1000 is grasped, the rotating electric machine 300 continues to rotate left, and the lower spring tray 530 cannot continue to rotate because the left positioning pin 950 contacts with the horizontal position blocking cam bearing follower 720, and the upper spring tray 500 and the spring tray rotating shaft 400 can continue to rotate at this time because the tension spring 540 is used for soft connection; when the first edge 131 of the motor rotating photo-blocking piece 130 completely blocks the motor horizontal position resetting photo-switch 110, the rotating motor 300 stops moving and maintains the current state, and the tension spring 540 is in a stretched state, so that the left positioning pin 950 is completely ensured to be firmly contacted with the horizontal position blocking cam bearing follower 720 and no virtual position is generated.
When the device moves to a required position, the rotating motor 300 continuously drives the spring tray rotating shaft 400 to rotate, the front oval follower post 510 and the rear oval follower post 520 are tangential to the left finger moving cam follower 960 and the right finger moving cam follower 980 while the spring tray rotating shaft 400 continuously rotates, at this time, the lower spring tray 530 does not rotate relatively, the left finger 930 and the right finger 940 can be opened to two sides, the left positioning pin 950 and the right positioning pin 970 can not generate great friction force due to the cam bearing follower when moving to the left and right, the same side fingers can be conveniently opened, and when the clamping jaw opening photoelectric barrier 160 completely shields the clamping jaw opening photoelectric switch 170, the rotating motor 300 stops moving.
When the left finger 930 and the right finger 940 reach the appropriate positions, the reaction cup 1000 is grasped as follows:
The rotating motor 300 rotates in the opposite direction (counterclockwise) by a certain angle, which may be larger because the front and rear elliptical follower posts 510, 520 need only reverse by a small angle (the reverse angle is based on the front and rear elliptical follower posts 510, 520 leaving the left and right finger moving cam followers 960, 980) under the action of the left and right return springs 927, 928, the left and right fingers 930, 940 are centered to grasp the cuvette 1000.
When the spring tray rotating shaft 400 rotates in the opposite direction (anticlockwise rotation) by a certain angle, the five tension springs 540 are still in a stretched state, the left side of the left positioning pin 950 is still horizontally limited, the left finger 930 and the right finger 940 do not horizontally rotate, only the grabbing reaction cup 1000 is closed, the opposite direction rotation angle margin of the rotating motor 300 is larger, and only the left positioning pin 950 and the horizontal position blocking cam bearing follower 720 are required to be tightly tangent.
According to the invention, the thickness of the reaction cup 1000 is 7mm, the distance between the left finger 930 and the right finger 940 in the initial state is 6mm, the maximum opening degree of the left finger 930 and the right finger 940 is 9mm, when the left finger 930 and the right finger 940 grasp the reaction cup 1000, the reaction cup is provided with the no-electricity baffle sheet and can not shield the reaction cup from having the no-electricity switch 140, at the moment, the reaction cup 1000 can be judged to be grasped, and if the reaction cup is provided with the no-electricity baffle sheet and shields the reaction cup from having the no-electricity switch 140, the grasping action is indicated to not grasp the reaction cup 1000 at the moment.
The reaction cup 1000 rotates: when the reaction cup 1000 is detected to be grabbed, after the reaction cup 1000 is moved to a required position, the rotating motor 300 continues to rotate anticlockwise, the spring tray rotating shaft 400 drives the lower spring tray 530, the left finger 930, the right finger 940 and the reaction cup 1000 to rotate together under the action of the five tension springs 540, when the vertical position photoelectric baffle 840 completely shields the cup vertical position photoelectric switch 830, the reaction cup 1000 is proved to rotate in place at this time, the right positioning pin 970 and the vertical position blocking cam bearing follower 820 are in contact with each other at this time, limiting is generated, in order to ensure that the position is more accurate, the generation of a virtual position is avoided, the rotating motor 300 continues to rotate at this time, when one end of the second side line 132 of the motor rotating photoelectric baffle 130 completely shields the motor vertical position reset photoelectric switch 120, the rotating motor 300 is stopped and maintained, at this time, the right positioning pin 970 can be ensured to be in close contact with the vertical position blocking cam bearing follower 820 under the action of the tension springs 540, and no virtual position is generated.
When the reaction cup 1000 is put at a proper position, the rotating motor 300 continues to move anticlockwise, the spring tray rotating shaft 400 drives the front oval follower column 510 and the rear oval follower column 520 to be tangent to the left finger moving cam follower 960 and the right finger moving cam follower 980, the left finger 930 and the right finger 940 are opened to two sides, when the clamping jaw opening photoelectric baffle 160 blocks the clamping jaw opening photoelectric switch 170, the rotating motor 300 stops rotating, and at the moment, the left finger 930 and the right finger 940 are completely opened in place, and the reaction cup 1000 smoothly falls down.
The rotating motor 300 rotates clockwise to the position of the first edge 131 of the motor rotating photoelectric blocking piece 130, completely covers the motor horizontal position resetting photoelectric switch 110, and meanwhile, the horizontal position photoelectric switch 730 judges whether the motor is covered or not, and further judges whether the motor rotates in place, so that the rotary grabbing reaction cup device completes a cup grabbing action for one period.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
