The present embodiment further provides a fluorescence immunoassay analyzer, which includes a wiring device, and therefore, the technical advantages and effects achieved by the fluorescence immunoassay analyzer also include the technical advantages and effects achieved by the wiring device, which are not described herein again.
Referring to fig. 1 to 5, the wiring device provided in this embodiment includes an actuator 200, a control circuit board 300, and a cable 400 electrically connecting the actuator 200 and the control circuit board 300, and further includes an adaptor 100; the adapter 100 is arranged on one side of the reciprocating motion path of the execution component 200 close to the control circuit board 300, and the orthographic projection of the adapter 100 on the straight line of the reciprocating motion path of the execution component 200 is positioned between two ends of the reciprocating motion path of the execution component 200; the transition piece 100 is used to wind the cable 400 to support the cable 400.
The adaptor 100 and the control circuit board 300 are arranged on the same side of the reciprocating motion path of the executing component 200, and the adaptor 100 does not exceed the reciprocating motion path along the extending direction of the reciprocating motion path, so that the bending degree of the cable 400 at the connecting end of the cable 400 and the position of the adaptor 100 is reduced to a certain extent during wiring; the cable 400 is divided into two sections by the adaptor 100, namely the cable 400 between the control circuit board 300 and the adaptor 100 and the cable 400 between the adaptor 100 and the executing component 200, when the executing component 200 reciprocates, the cable 400 between the adaptor 100 and the executing component 200 swings around the adaptor 100, and the length is correspondingly reduced or increased, accordingly, the length of the cable 400 between the control circuit board 300 and the adaptor 100 is correspondingly increased or reduced, and in the whole change process of the cable 400, the bending degree of the connecting end of the cable 400 is correspondingly changed, but due to the arrangement of the adaptor 100, the maximum bending degree is smaller than the maximum bending degree of the cable 400 without the adaptor 100, so that the failure rate is reduced, the problem that the cable 400 at the connecting end is broken or has poor contact is avoided, and the normal operation of corresponding equipment is ensured.
In the present embodiment, referring to fig. 2 and 3, the distance between the reciprocating paths of the adaptor 100 and the actuator 200 is H1, and the distance between the connection end of the cable 400 electrically connected to the control circuit board 300 and the reciprocating path of the actuator 200 is H2, where H1 < H2.
With reference to fig. 2, the reciprocating path of the actuating member 200 is used as a reference bottom line, and the height of the adaptor 100 is lower than the height of the connection end of the cable 400 and the control circuit board 300, so that the bending degree of the cable 400 wound around the adaptor 100 is reduced, the service length of the cable 400 is also shortened, and the material cost is saved.
Further, referring to fig. 4, the orthographic projection of the adaptor 100 on the reciprocating path of the actuator 200 is in the middle of the reciprocating path of the actuator 200.
With reference to fig. 4, the left and right ends of the reciprocating path are the extreme movement positions of the actuating component 200, the adaptor 100 is located right above the reciprocating path, and with reference to fig. 5, when the push-pull control handpiece of the actuating component 200 moves back and forth, i.e., when the reagent card located on the reagent card insertion slot 800 is pushed out or pulled into the fluorescence immunoassay analyzer, the bending degree of the connecting end of the cable 400 electrically connected with the push-pull control handpiece changes correspondingly, and when the cable 400 is located at the card advance extreme position and the card retreat extreme position, the bending degree of the cable 400 is the maximum, but due to the arrangement of the adaptor 100, the maximum bending degree is smaller than the maximum bending degree of the cable 400 without the adaptor 100, thereby reducing the failure rate.
Further, referring to fig. 1, the adaptor 100 is pivoted to the plate-shaped sideframe 500, the adaptor 100 has an outer circumferential surface for winding the cable 400 to support the cable 400, and the adaptor 100 rotates around the pivoting axis along with the movement of the cable 400 in the reciprocating movement condition.
With reference to fig. 1, the adaptor 100 is of a driven wheel structure and is pivoted to the plate-shaped sidecar frame 500, when the actuator 200 moves, the lengths of the cable 400 between the control circuit board 300 and the adaptor 100 and the cable 400 between the adaptor 100 and the actuator 200 change correspondingly, so as to drive the adaptor 100 to rotate clockwise or counterclockwise around the pivot axis thereof, further change the friction between the cable 400 and the adaptor 100 into rolling friction, reduce the friction loss of the cable 400, and simultaneously reduce the obstruction of the friction on the movement of the actuator 200, thereby ensuring the smooth reciprocating movement.
In the present embodiment, referring to fig. 1, the wiring device further includes a cable holder 600; the cable holder 600 is fixedly disposed at the plate-shaped sideframe 500 and adjacent to the control circuit board 300, and the cable holder 600 is used to fasten the cable 400 between the control circuit board 300 and the adaptor 100.
Specifically, the cable 400 between the control circuit board 300 and the adaptor 100 passes through the cable fixing member 600, and the cable fixing member 600 plays a role in bundling and fastening the cable 400, and furthermore, the cable 400 between the control circuit board 300 and the cable fixing member 600 keeps a static state and is not influenced by the movement of the executing component 200, that is, when the cable 400 between the adaptor 100 and the executing component 200 swings, the movement of the cable 400 cannot be transmitted to the connecting end of the cable 400 electrically connected with the control circuit board 300, so that the interface of the connecting end and the control circuit board 300 is prevented from loosening, and the occurrence of poor contact is avoided.
Further, referring to fig. 4, the cable fixing element 600 and the line segment of the reciprocating path of the actuating member 200 enclose a triangular area; the orthographic projection of the adapter 100 on the plane of the plate-like lateral frame 500 is outside the orthographic projection of the triangular area on the plane of the plate-like lateral frame 500.
Referring to fig. 1 and 4, since the actuator 200 is spaced apart from the surface of the plate-shaped sidecar frame 500 and the adaptor 100 is fixedly disposed on the surface of the plate-shaped sidecar frame 500, the connection end of the cable 400 to the actuator 200 is bent to some extent, and by disposing the adaptor 100 above the line connecting the cable fixing member 600 and the right end of the reciprocating path, the bending degree is reduced, thereby protecting the cable 400.
Further, referring to fig. 3 and 4, the wiring device further includes a buffer member 700, the buffer member 700 being disposed on the plate-shaped sideframe 500 and between the cable holder 600 and the adaptor 100; the buffer member 700 is used for winding the cable 400 between the cable holder 600 and the adaptor 100, so that the cable 400 between the cable holder 600 and the adaptor 100 forms a V-shape with an opening facing away from the reciprocating path of the actuating member 200.
The advantage of the above arrangement is that when the length of the cable 400 between the cable fixing member 600 and the adapter 100 is reduced along with the movement of the actuating member 200, the stress generated in the reducing process is buffered by the buffer member 700, so that the force of the cable 400 acting on the cable fixing member 600 is reduced, and the friction damage of the cable fixing member 600 to the cable 400 is reduced.
Further, with continued reference to fig. 3 and 4, the damper 700 is a driven wheel and is pivotally connected to the plate-shaped sideframe 500, and the damper 700 is rotatable about the pivotal axis in response to the movement of the cable 400.
When the actuating member 200 reciprocates, the length of the cable 400 contacting the buffer member 700 changes, so as to drive the buffer member 700 to rotate counterclockwise or clockwise around the pivot axis thereof, that is, the friction between the cable 400 and the buffer member 700 is rolling friction, thereby reducing the friction loss of the cable 400.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that various changes and modifications may be made therein, and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
