Description

Technical Field

[0001] The invention belongs to the technical field of test paper production, and in particular relates to a separation and transfer mechanism for medical diagnostic test paper. Background Art

[0002] Medical testing is a science that conducts microbiological, immunological, biochemical, genetic, hematological, biophysical, cytological and other tests on materials taken from the human body, thereby providing information for the prevention, diagnosis, and treatment of human diseases and the assessment of human health.

[0003] Currently, various test strips are commonly used in the medical testing industry, such as colloidal gold test strips and immunofluorescence test strips. In the production process of test strips, large sheets of test strips need to be cut. The cut test strips need to be sorted at equal intervals and transferred one by one for visual defect detection or assembly for subsequent operations.

[0004] Currently, in the production of test strips, the test strips cut by the cutting machine are manually screened one by one. This method is not convenient for the realization of automated production, has low production capacity, and consumes a lot of manpower costs.

[0005] In the existing technical solutions, such as the feeding device, test paper bottle feeding device and test paper cutting machine with authorization announcement number CN 212711996 U, the feeding device transports the cut test paper strips to the bottle feeding device, and transports them through a combination of a feeding table and a scanning claw. However, this transportation method converts the test paper from a scattered flat state to an accumulated state and directly feeds it into the bottle. In the accumulated state, the test paper strips cannot be visually inspected for defects, and the quality of the test paper strips cannot be guaranteed. If inspection is required, manual screening is still required one by one, which will cause human injuries, low efficiency and high labor costs.

[0006] For example, the application announcement number CN 109291094 A discloses an automatic cutting, sorting, and sequencing device for test strips. The cut test strips are sorted and sequenced through a sorting mechanism and positioning fixtures. However, this sorting method requires a side push block to push the cut test strips into a track and then into a positioning hole. The sorting and positioning procedure is relatively complex and inefficient, and the number of positioning holes is limited, so the positioning structure is also relatively complex.

[0007] In order to solve the above technical problems, the present invention proposes a separation and transfer mechanism for medical diagnostic test strips. Summary of the Invention

[0008] The purpose of the present invention is to overcome the shortcomings of the existing technology and propose a separation and transfer mechanism for medical diagnostic test strips, which can sort and transport the cut test strips at equal intervals, facilitate visual defect detection one by one, avoid contamination caused by manual screening, and reduce manpower; at the same time, simplify the sorting and positioning structure, improve efficiency, and thus realize full automation of the separation and transfer process.

[0009] To achieve the above objectives, the present invention proposes the following technical solutions:

[0010] A separation and transfer mechanism for medical diagnostic test strips, comprising a main motor, a coupling, a first shaft, a bottom plate, a rear plate, a top plate, a first linkage structure, a second linkage structure, a transverse moving plate, a clamping structure, a second shaft, and a rear chute; the main motor is connected to the first shaft via a coupling;

[0011] Both ends of the first shaft are mounted below the top plate via bearings; the top plate is connected to the bottom plate via a rear plate to form a bracket;

[0012] The lateral moving plate is slidably connected to the top plate, limiting the movement trajectory of the lateral moving plate so that the lateral moving plate has only one degree of freedom in one direction and can only move horizontally;

[0013] The clamping structure includes a vertical plate, an upper clamping plate, a lower clamping plate, a side connecting plate and a swing connecting block; the clamping structure is provided in two groups, which are symmetrically arranged on the transverse movable plate.

[0014] The two ends of the second shaft are respectively connected to the two clamping structures; the vertical plate is vertically arranged on the horizontal movable plate; the vertical plate is provided with placement grooves with equal spacing;

[0015] The side connecting plate is connected to the upper clamping plate to form a right-angle clamping plate; the side connecting plate is slidably connected to the vertical plate, and the side connecting plate can slide up and down along the vertical plate;

[0016] A horizontal plate is provided above the lower clamping plate, corresponding to the upper clamping plate, to form a clamping space;

[0017] The side connecting plate, the vertical plate and the lower clamping plate are provided with a vertical long hole at the same position, and the second shaft passes through the vertical long holes of the lower clamping plate, the vertical plate and the side connecting plate in sequence; the end of the second shaft is connected to the side connecting plate through a swing connecting block, and the second shaft can move up and down in the vertical long hole; the second shaft is hinged to the swing connecting block, and the swing connecting block is fixedly connected to the side connecting plate;

[0018] The first linkage structure includes a first cam, a first connecting rod, a transverse slider, and a second connecting rod. The first cam is installed on the first shaft. The first cam is connected to the first connecting rod and the transverse slider in sequence. The transverse slider remains in a horizontal state and moves up and down with the rotation of the first cam. The second connecting rod is in a "7" shape. The lower end of the second connecting rod is slidably connected to the transverse slider and can move horizontally along the transverse slider. A hole is opened at the corner of the second connecting rod for the second shaft to pass through. The upper end of the second connecting rod is fixedly connected to the lower splint.

[0019] As the first cam rotates, the transverse slider moves up and down, driving the second connecting rod to move horizontally and up and down at the same time, thereby forming a swinging state of the upper end of the second connecting rod, and the lower splint moves up and down with the swing of the second connecting rod. The second shaft moves up and down along the long hole with the swing of the second connecting rod, thereby driving the hinged end of the swing connecting block to move up and down, and the fixed end of the swing connecting block moves up and down in the opposite direction, thereby forming the upper and lower splints approaching and moving away from each other, that is, a clamping state and a loosened state.

[0020] The second linkage structure includes a second cam and a third connecting rod. The second cam is arranged on the first shaft. The second cam is fixedly connected to the transverse moving plate through the third connecting rod. As the second cam rotates, the transverse moving plate realizes horizontal transverse movement. The moving distance of the transverse moving plate each time is consistent with the spacing of the placement grooves.

[0021] The rear chute is arranged behind the clamping structure and is used to receive and transfer the test strips.

[0022] Preferably, it also includes an intelligent visual inspection system, which includes an industrial camera, an unqualified receiving slide and an intelligent control terminal. The industrial camera is mounted above the clamping structure, and the unqualified receiving slide is arranged behind the clamping structure through a rotating arm, and the rotating arm is rotated by a rotating motor; the intelligent control terminal is connected to the industrial camera and the rotating motor respectively, and the industrial camera performs image detection on the test strip that is about to fall from the clamping structure, and sends a signal to the intelligent control terminal according to the actual situation of the test strip. The intelligent control terminal determines the corresponding judgment result based on the signal, that is, qualified or unqualified, and then sends an instruction to the rotating motor. If qualified, the rotating motor drives the rotating arm to rotate, and then drives the unqualified receiving slide to move to the rear of the clamping structure, so that the unqualified test strip falls into the unqualified receiving slide. If qualified, the rotating motor does not start, and the qualified test strip falls normally into the rear chute for subsequent operations and collection and packaging.

[0023] In particular, the above-mentioned industrial camera, unqualified receiving slide and intelligent control terminal are all commonly used mechanical equipment in the prior art and can be used directly.

[0024] Preferably, there are two or more placement grooves.

[0025] Preferably, the number of the placement grooves is 10 to 20.

[0026] Preferably, the lower portion of the transverse movable plate and the upper portion of the top plate are slidably connected via a linear guide rail.

[0027] Preferably, both sides of the vertical plate are slidably connected to the side connecting plates and the lower clamping plate through linear guide rails.

[0028] Specifically, the device sequentially performs the actions of gripping, separating at equal intervals, moving the stack horizontally, and removing the stack one by one;

[0029] The first step is clamping, that is, clamping the cut test strip. Specifically, the main motor drives the first shaft to rotate, which in turn drives the second cam in the second linkage structure to rotate. At the same time, the third connecting rod drives the transverse movable plate to move transversely, and the clamping structure on the transverse movable plate moves to the end of the test strip. Then, the first cam in the first linkage structure drives the clamping structure to achieve a clamping state through the first connecting rod, the transverse slider and the second connecting rod. After the test strip is cut, the transverse movable plate is reset laterally, thereby driving the test strip to move to the first placement groove above the vertical plate; then, the clamping structure switches to a released state to perform the next clamping action, and the transverse movable plate moves transversely again, and the clamping structure moves to the end of the test strip. The clamping structure switches to a clamping state. After the test strip is cut, the transverse movable plate is reset laterally, thereby driving the test strip to move to the first placement groove above the vertical plate, and at the same time, the first test strip moves into the second placement groove;

[0030] The above clamping action is repeated until the first test strip moves to the last placement groove, thus completing the separation of the test strips at equal intervals.

[0031] Then the first test strip is separated from the last placement groove as the next clamping action is carried out, and falls into the rear chute, and then the test strips fall one by one, completing the stack-type horizontal movement and moving out of the stack one by one.

[0032] The beneficial effects of the present invention are:

[0033] The present invention provides a main motor to drive the entire mechanical structure, and the power structure is simple;

[0034] The present invention realizes synchronous operation of clamping and lateral movement through the first linkage structure and the second linkage structure, has a simple structure, a high degree of automation, and can complete the work efficiently;

[0035] The present invention arranges a first linkage structure, a second linkage structure, a transverse movable plate, a clamping structure, a second shaft and a rear slide groove, and a vertical plate is provided with placement grooves at equal intervals. The first linkage structure, the second linkage structure and the vertical plate cooperate to realize the sorting and transportation of test strips at equal intervals, facilitates visual defect detection one by one, avoids contamination caused by manual screening, and reduces labor.

[0036] The present invention realizes the sorting and positioning effect of the test strips through the mutual cooperation of the first linkage structure and the second linkage structure, simplifies the structure, improves the efficiency, and further realizes the full automation of the separation and transfer procedure.

[0037] By adopting the above scheme, the present invention can sort and transport the cut test strips at equal intervals, facilitate visual defect detection one by one, avoid contamination from manual screening, and reduce manpower; at the same time, simplify the sorting and positioning structure, improve efficiency, and thus realize full automation of the separation and transfer process.
