Description

Technical Field

[0001] The utility model relates to the technical field of colloidal gold detection cards, in particular to a colloidal gold detection large card assembly positioning mold used in the production of colloidal gold detection cards. Background Art

[0002] At present, the production process of colloidal gold detection card is to manually paste the gold pad 200 and the sample pad 300 (such as Figure 2 As shown), and then assemble (the process of assembling and pasting the coating film 100, the gold pad 200, and the sample pad 300 is called assembling) into a colloidal gold detection card, and then cut the assembled colloidal gold detection card along the width direction into a plurality of colloidal gold detection card finished products.

[0003] Currently, when assembling the gold pad and the sample pad, there is no standard pasting positioning mold, and most operators operate based on their experience. At this time, due to the difference in proficiency of different operators, the pasting positions of the gold pad 200 and the sample pad 300 deviate or are skewed, which in turn affects the quality of the colloidal gold test card after the assembly is completed. Even when the pasting positions of the gold pad 200 and the sample pad 300 have a large deviation, rework is required, which greatly increases the workload and reduces the production efficiency of the colloidal gold test card. Summary of the invention

[0004] The utility model aims to provide a colloidal gold detection large card group sticker positioning mold to address the defects of the prior art.

[0005] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0006] The colloidal gold detection large card group positioning mold described in the utility model comprises a box body with an upper opening and a box cover adapted to be buckled on the box body; a pair of horizontal racks with tooth surfaces facing each other are arranged in parallel in the box body, a pair of horizontally rotating gears are arranged in the box body between the two horizontal racks, the two gears are meshed with the two horizontal racks in a one-to-one correspondence to push the horizontal racks to extend from the front side wall of the box body, the upper end of the core shaft of the gear vertically passes through the top wall of the box cover, and a knob is arranged at the passing end; a pair of mutually parallel horizontal brackets are arranged on the outer side surface of the front side wall of the box body, the two horizontal racks are located between the two horizontal brackets, a pair of horizontal guide grooves with notches facing each other are arranged on the relative inner sides of the two horizontal brackets, and a transparent positioning plate of a rectangular structure connected to the passing end of the horizontal rack is slidably arranged in the horizontal guide groove.

[0007] Furthermore, a pair of guide grooves are provided in the box body, and the two horizontal racks are adapted to be inserted into the two guide grooves in a one-to-one manner. Openings are provided on the opposite side walls of the two guide grooves, and the gears extend into the guide grooves from the openings and mesh with the horizontal racks, thereby limiting the extension and retraction direction of the horizontal racks through the guide grooves, thereby forming a stable guiding effect on the horizontal racks.

[0008] Furthermore, anti-skid ridges are evenly distributed on the side walls of the knob, thereby increasing the friction when the knob is gripped and turned.

[0009] Furthermore, a scale is provided on the horizontal bracket, and the direction of the scale should be consistent with the length direction of the horizontal guide groove, so as to improve the accuracy of the transparent positioning plate when moving.

[0010] The utility model has the advantages that the gears are driven to rotate by synchronously turning the two knobs in opposite directions or in opposite directions, thereby driving the two horizontal racks to synchronously extend and retract horizontally, and pushing the transparent positioning plate to translate along the horizontal guide groove, so that the long side of the transparent positioning plate away from the box body is used as a positioning line, and the accurate pasting of the gold pad and the sample pad when assembling the colloidal gold detection large card is easily achieved, avoiding the operator to paste the gold pad and the sample pad based on experience, and effectively preventing the pasting position of the gold pad and the sample pad from deviation or skewness, thereby ensuring the quality of the assembly of the colloidal gold detection large card, avoiding repeated rework, reducing the workload of the operator, and enabling novices to easily complete the accurate assembly of the colloidal gold detection large card.

[0012] Figure 2 It is a schematic diagram of the structure of an existing colloidal gold detection card. DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0015] like Figure 1As shown, the colloidal gold detection large card assembly positioning mold described in the utility model includes a box body 1 with an upper opening, and a box cover 2 that is adapted to be snapped onto the box body 1. The box body 1 and the box cover 2 are connected in a detachable manner, which is not only convenient for independent processing, but also can be quickly assembled together.

[0016] A pair of horizontal racks 3 with tooth surfaces facing each other are arranged in parallel in the box body 1, and a pair of horizontally rotating gears 4 are arranged in the box body 1 between the two horizontal racks 3, and the two gears 4 mesh with the two horizontal racks 3 in a one-to-one correspondence. Specifically, the mandrels of the two gears 4 are perpendicular to the bottom wall of the box body 1, and the lower ends of the mandrels are adapted to be inserted into the cylindrical shaft seat arranged on the bottom wall of the box body 1, so as to easily realize the hinge connection between the gears 4 and the box body 1, and ensure that the gears 4 can rotate horizontally in the box body 1; at the same time, holes corresponding to the two horizontal racks 3 should be opened on the front side wall of the box body 1, so that the horizontal racks 3 can be pushed forward from the front side wall of the box body 1 through the horizontal rotation of the gears 4. In addition, in order to facilitate the operation of the horizontal rotation of the gears 4, the upper ends of the mandrels of the two gears 4 should vertically pass through the top wall of the box cover 2, and a knob 5 for convenient twisting should be set at the passing end.

[0017] A pair of parallel horizontal brackets 6 are arranged on the outer side surface of the front side wall of the box body 1, and the two horizontal racks 3 should be located between the two horizontal brackets 6. A pair of horizontal guide grooves 7 with notches facing each other are arranged on the opposite inner sides of the two horizontal brackets 6, and a transparent positioning plate 8 with a rectangular structure connected to the protruding end of the horizontal rack 3 is slidably arranged in the horizontal guide groove 7.

[0018] Furthermore, in order to ensure that the two horizontal racks 3 can always be extended and retracted forward and backward in parallel and stably, a pair of guide grooves 9 can be set in the box body 1, and the two horizontal racks 3 are adapted to be penetrated in the two guide grooves 9 one by one, so that the extension and retraction direction of the horizontal racks 3 is limited by the guide grooves 9, forming a stable guiding effect on the horizontal racks 3; at this time, openings 10 should also be opened on the opposite side walls of the two guide grooves 9, so that the gear 4 can extend into the guide groove 9 from the opening 10, and then mesh with the horizontal rack 3.

[0019] Furthermore, in order to ensure that the knob 5 can be screwed better, anti-skid ridges 11 can be evenly distributed on the side wall of the knob 5, so as to increase the friction when the knob 5 is gripped and screwed.

[0020] Furthermore, in order to accurately adjust the moving position of the transparent positioning plate 8, a scale 12 can also be set on the horizontal bracket 6. The direction of the scale 12 should be consistent with the length direction of the horizontal guide groove 7, and it is set on the upper surface of the horizontal bracket 6. Therefore, when adjusting the transparent positioning plate 8 to move along the horizontal guide groove 7, the moving position of the transparent positioning plate 8 can be accurately adjusted according to the corresponding position of the long side of the transparent positioning plate 8 away from the box body 1 and the scale 12, thereby improving the movement accuracy of the transparent positioning plate 8.

[0021] When performing colloidal gold detection of large card sets, first, the coating film 100 coated with the detection reagent is placed between the two horizontal brackets 6. Generally, the width of the coating film 100 is consistent with the spacing between the two horizontal brackets 6. Then, according to the specified position of the gold pad 200 or the sample pad 300 to be pasted on the coating film 100, the two knobs 5 are synchronously turned toward or away from each other, driving the two horizontal racks 3 to synchronously extend forward or retract backward, thereby driving the transparent positioning plate 8 to slide along the horizontal guide groove 7 through the forward and backward extension of the two horizontal racks 3, and the transparent positioning plate 8 is extended away from the box body 1. The gold pad 200 and the sample pad 300 are positioned on the coating film 100 in sequence while being adjusted to the specified position, and the long side of the transparent positioning plate 8 away from the box body 1 is used as a positioning line. The gold pad 200 and the sample pad 300 are positioned in sequence on the coating film 100, so that the accurate pasting of the gold pad 200 and the sample pad 300 can be easily achieved, and the operator can avoid pasting the gold pad 200 and the sample pad 300 based on experience, and the pasting position of the gold pad 200 and the sample pad 300 can be effectively prevented from deviation or skewness, so as to ensure the quality of the colloidal gold detection large card assembly, avoid repeated rework, reduce the workload of the operator, and enable novices to easily complete the accurate assembly of the colloidal gold detection large card.
