Description

Technical Field

[0001] The present invention relates to the technical field of kit assembly, and in particular to an assembly device for a kit. Background Art

[0002] As an important tool for tumor-related research and treatment, tumor test kits are widely used in early screening, diagnosis and treatment monitoring. Currently, tumor test kits on the market are mainly composed of an upper cover plate, a lower cover plate and a test strip fixed between the two. The upper and lower covers are manufactured by injection molding and are joined by snap-fitting.

[0003] Referring to the Chinese patent document with authorization announcement number CN116571982B and announcement date December 12, 2023, entitled A tumor gene detection kit assembly device, the invention comprises an assembly truncated table, the lower end of which is provided with a support leg for supporting the assembly truncated table; an assembly port opened on the assembly truncated table, the assembly port is square and is provided with a plurality of ports, an assembly operation unit is provided on the assembly truncated table, and a conveyor belt is provided correspondingly below one of the assembly ports; a test kit is provided in the assembly port, a box cover is placed above the test kit, and when the box cover is squeezed to move downward, corresponding mating convex strips for fixing are provided on the box cover and the test kit, and the box cover moves downward. At this time, the test kit is supported by the elastic force of the reset spring, the test kit does not move, and the box cover moves downward to pass through the convex strip.

[0004] However, since the upper and lower covers are made of plastic materials, internal stress is easily generated during processing. During storage or use, the internal stress is gradually released, causing the cover to warp or deform. In addition, plastic materials are easily deformed due to temperature and humidity. During transportation and storage, the cover is easily deformed due to external forces. There are thickness differences and structural design differences between the upper and lower covers, and the upper cover needs to withstand more external forces during the assembly of the test kit, which makes the upper cover more prone to deformation. When the test kit is assembled using existing equipment, the warped and deformed upper cover is not taken into account, which will cause assembly difficulties. The upper and lower covers are difficult to assemble, and may cause the upper cover to get stuck in the equipment or break, affecting production efficiency, reducing the yield rate, and causing waste. Summary of the invention

[0005] In view of this, the present invention provides an assembly device for a test kit, aiming to solve the technical problem in the prior art that deformation of the upper cover plate affects the assembly efficiency and yield rate of the test kit.

[0006] In order to solve the above technical problems, the present invention provides an assembly device for a test kit, which adopts the following technical solution: an assembly device for a test kit, comprising an assembly body, an assembly table rotating around its own vertical axis, and a conveyor belt located below the assembly table, the conveyor belt is used to convey the lower cover plate, and a plurality of press boxes are arranged below the assembly table and along the circumference of the assembly table, the press box is composed of an upper press cover and a lower press cover, and the cavity between the upper press cover and the lower press cover is used to accommodate the upper cover plate; a moving rod vertically slidably connected to the assembly table is fixedly connected to the top of the upper press cover, a driving member for driving the moving rod to slide is provided above the assembly table, and a driving member for supplying the upper cover to the upper press cover is provided on one side of the assembly body. The feeding part of the plate, the bottom surface of the upper pressure cover is provided with a lock hole corresponding to the lock pin of the upper cover plate, and a rubber ring sleeved on the lock pin is provided in the lock hole, and a heating element is provided in the upper pressure cover; the lower pressure cover is connected to the moving rod through a connecting rod, the lower pressure cover is located below the upper pressure cover, and a rotating part is provided on the connecting rod, and the rotating part is used to control the lower pressure cover to rotate around the horizontal axis located at the bottom of the connecting rod; a flat plate is slidably inserted in the lower pressure cover and can cooperate with the bottom surface of the upper pressure cover to flatten the upper cover, the inside of the flat plate is hollow, and the bottom surface of the flat plate is connected to a ventilation pipe penetrating the bottom of the lower pressure cover, and a negative pressure suction hole is provided on the top surface of the flat plate, and a control part that can drive the flat plate to move along the height direction of the lower pressure cover is provided between the lower pressure cover and the flat plate.

[0007] By adopting the above technical solution, the upper pressure cover is matched with the upper cover plate, and the locking pin of the upper cover plate is inserted into the rubber ring in a one-to-one corresponding manner. The rubber ring surrounds and presses the locking pin, so that the upper cover plate can move synchronously with the upper pressure cover; the rotating member controls the rotation of the lower pressure cover, the lower pressure cover cooperates with the upper pressure cover, and the upper cover plate is located between the upper pressure cover and the lower pressure cover; under the action of the control member, the expansion plate moves, and the expansion plate cooperates with the upper pressure cover to squeeze the upper cover plate and restore the upper cover plate to a flat state, the upper pressure cover heats the upper cover plate, and shapes the upper cover plate so that it can maintain a flat state; after the shaping is completed, the upper cover plate is adsorbed on the lower pressure cover through the ventilation pipe and the negative pressure suction hole, and the rotating motor controls the rotation of the lower pressure cover again, so that the locking pin of the upper cover plate faces downward and corresponds to the lower cover plate on the conveyor belt, and under the action of the driving member, the upper cover plate moves downward and covers the lower cover plate to complete the assembly of the test kit.

[0008] By flattening and heating the upper cover, the warping and deformation of the upper cover are corrected and the upper cover is restored to a flat state, which is convenient for subsequent assembly, thereby improving the assembly efficiency and yield rate of the test kit. In the process of the upper cover being transported by the assembly round table, the upper cover is flattened and heated. The setting of the rotating motor and the negative pressure suction hole is also conducive to cooling the upper cover. There is no need to move the position of the upper cover multiple times, which shortens the process and reduces the footprint of the device. The device is flexible and easy to use.

When the external air intake device blows air into the internal cavity of the vent pipe and the expansion plate, the sealing plate seals the end of the guide tube under the action of the tension spring. As the gas enters, the gas pushes the expansion plate to move, so that the expansion plate abuts against the upper cover plate, thereby achieving the purpose of flattening the upper cover plate. When the external air extraction device extracts the air inside the vent pipe and the expansion plate, under the action of the gas pressure difference, the sliding block and the sealing plate move, so that a gap is left between the sealing plate and the guide tube, and a gap is left between the support rods.

[0014] By adopting the above technical solution, at the loading point and the unloading point, the output end of the cylinder abuts against the top of the moving rod, so that the upper cover plate moves downward to complete the loading and unloading. After the output end of the cylinder is separated from the moving rod, the moving rod moves upward under the action of the return spring, reducing the conflict between the upper pressure cover and other structures, which is conducive to simplifying the structure and realizing automatic assembly line processing.

[0015] Optionally, the heating element comprises a heating plate.

Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0036] The following is combined with Figure 1 -Attached Figure 7 The present invention is described in further detail.

[0037] The embodiment of the present invention discloses an assembly device for a reagent kit. Figures 1 to 7 An assembly device for a test kit includes an assembly body 1, a loading member 2, an assembly table 3, an upper pressure cover 4, a driving member 5, a lower pressure cover 6, a flat plate 7, a control member 8 and a conveyor belt 9. An upper pressure cover 4 and a lower pressure cover 6 constitute a pressure box that can accommodate a flattened upper cover.

[0038] Reference Figure 1 The assembled body 1 is in a rectangular shape as a whole and is used to install other structures.

[0039] Reference Figure 1 , Figure 2 and Figure 5 The feeding member 2 is used to feed the upper cover plate in sequence. The feeding member 2 includes a feeding box 21, a push spring 22, a feeding slot 23, a sliding rod 24, a feeding plate 25 and a receiving plate 26. The loading box 21 is vertically placed on the assembly body 1. The loading box 21 is hollow inside. The loading box 21 is used to hold multiple vertically arranged upper cover plates. The pushing spring 22 is vertically arranged at the bottom of the internal cavity of the loading box 21. The pushing spring 22 is used to push the upper cover plate in the loading box 21 so that the upper cover plate has a tendency to move upward. The loading trough 23 passes through the top of the side wall of the loading box 21 in the horizontal direction, and the loading trough 23 matches the upper cover plate located at the top of the loading box 21. The sliding rod 24 is slidably connected to the outer wall of the loading box 21. The loading plate 25 is horizontally placed. The loading plate 25 is connected to the end of the sliding rod 24. The loading plate 25 is slidably inserted into the loading trough 23. The loading plate 25 can push the upper cover plate of the loading trough 23. The receiving plate 26 is fixedly connected to the outer wall of the loading box 21, and the receiving plate 26 can receive the upper cover plate pushed to the outside of the loading box 21 by the loading plate 25.

[0040] The loading plate 25 pushes the upper cover plate at the top of the loading box 21 and pushes the upper cover plate onto the receiving plate 26. When the loading plate 25 moves outside the loading box 21, the pushing spring 22 inside the loading box 21 pushes multiple upper cover plates to move up, thereby realizing automatic loading of the upper cover plates and reducing the workload of workers.

[0041] Reference Figure 1The assembling table 3 is cylindrical as a whole, and is horizontally placed above the assembling body 1. A rotating drive motor 31 with an output end vertically upward is provided between the assembling table 3 and the assembling body 1. The rotating drive motor 31 is fixedly connected to the bottom surface of the assembling table 3. When the rotating drive motor 31 is started, the assembling table 3 is driven to rotate, so as to drive the upper cover plate on the assembling table 3 to move.

[0042] Reference Figure 1 and Figure 5 The upper pressure cover 4 is arranged between the assembly truncated table 3 and the assembly body 1. The upper pressure cover 4 is in the shape of a rectangular parallelepiped as a whole. The upper pressure cover 4 is arranged horizontally. The upper pressure cover 4 is vertically slidably connected to the assembly truncated table 3. There are multiple upper pressure covers 4, and the multiple upper pressure covers 4 are evenly arranged along the circumference of the assembly truncated table 3.

[0043] Reference Figure 1 and Figure 5 The driving member 5 is used to drive the upper cover 4 to reciprocate in the vertical direction.

[0044] Reference Figure 1 and Figure 5 The driving member 5 includes a plurality of moving rods 51, a plurality of return springs 52, a support frame 53 and two cylinders 54. The plurality of moving rods 51 correspond to the upper pressure cover 4 one by one, the moving rods 51 are fixedly connected to the top surface of the upper pressure cover 4, the top of the moving rods 51 are slidably connected to the assembly truncated table 3, the return springs 52 are sleeved on the moving rods 51, the two ends of the return springs 52 are respectively connected to the top surface of the moving rods 51 and the top surface of the assembly truncated table 3, the support frame 53 is fixedly connected to the top surface of the assembly body 1, the top of the support frame 53 is located above the assembly truncated table 3, the two cylinders 54 are both fixedly connected to the support frame 53, the output ends of the cylinders 54 are vertically downward, and the two cylinders 54 correspond to the positions of the loading point and the unloading point of the upper cover plate respectively.

[0045] At the loading and unloading points, the output end of the cylinder 54 abuts against the top of the moving rod 51, causing the upper cover plate to move downward to complete loading and unloading. After the output end of the cylinder 54 separates from the moving rod 51, the moving rod 51 moves upward under the action of the return spring 52, reducing the conflict between the upper pressure cover 4 and other structures, which is conducive to simplifying the structure and realizing automatic assembly line processing.

[0046] Reference Figure 2 and Figure 3The feeding member 2 further includes a push rod 27, a first wedge block 28, a second wedge block 29 and a feeding spring 210. The push rod 27 is fixedly connected to the moving rod 51 and extends vertically downward. The first wedge block 28 is fixedly connected to the bottom of the push rod 27, and the second wedge block 29 is fixedly connected to the end of the sliding rod 24. The first wedge block 28 and the second wedge block 29 match each other, and the inclined surface of the first wedge block 28 abuts against the inclined surface of the second wedge block 29. The feeding spring 210 is sleeved on the sliding rod 24 and its two ends are respectively connected to the side wall of the second wedge block 29 and the outer wall of the feeding box 21.

[0047] During the downward movement of the upper pressure cover 4, the first wedge block 28 at the bottom of the push rod 27 pushes the second wedge block 29 and the sliding rod 24, so that the loading plate 25 moves to the outside of the loading box 21, and the bottom surface of the upper pressure cover 4 matches the top surface of the upper cover to complete the loading of the upper cover. After the loading is completed, the upper pressure cover 4 moves upward, and the second wedge block 29 and the sliding rod 24 move under the action of the loading spring 210. The loading plate 25 pushes the upper cover in the loading box 21 and pushes the upper cover onto the receiving plate 26, which is beneficial to control the timing of automatic loading of the upper cover and facilitates the realization of automatic assembly line processing.

[0048] Reference Figure 4 The bottom surface of the upper pressure cover 4 is provided with a lock hole 41 corresponding to the lock pin of the upper cover plate, and a rubber ring 42 is arranged in the lock hole 41. The inner cavity of the rubber ring 42 is in a truncated cone shape with a diameter gradually decreasing from bottom to top.

[0049] The rubber ring 42 can guide the locking pin of the upper cover plate, which is beneficial for the one-to-one correspondence between the locking pin and the rubber ring 42, and during the alignment process, the upper cover plate can be initially flattened.

[0050] Reference Figure 4 A heating element is arranged in the upper pressure cover 4. The heating element comprises a heating plate, which is not shown in the figure.

[0051] It can provide uniform heating, simplify equipment structure and reduce maintenance costs.

[0052] Reference Figure 3 and Figure 4 The lower pressure cover 6 is in the shape of a rectangular parallelepiped as a whole. The moving rod 51 is fixedly connected to a connecting rod 61 extending vertically downward. The lower pressure cover 6 is rotatably connected to the bottom of the connecting rod 61. The rotating member controls the rotation of the lower pressure cover 6. The rotating member includes a hinge shaft and a rotating motor 62. The hinge shaft is horizontally arranged at the bottom of the connecting rod 61. The rotating motor 62 is fixedly connected to the connecting rod 61. The output end of the rotating motor 62 is connected to the hinge shaft. When the rotating motor 62 is started, the hinge shaft can be driven to rotate, that is, the lower pressure cover 6 is driven to rotate. When the lower pressure cover 6 rotates to the bottom of the upper pressure cover 4, its top surface is connected to the bottom surface of the upper pressure cover 4, and they cooperate to form a pressure box. The upper cover plate is placed between the upper pressure cover 4 and the lower pressure cover 6.

[0053] Reference Figure 3 , Figure 6 and Figure 7 The expansion plate 7 is slidably inserted into the cavity of the lower pressure cover 6. The interior of the expansion plate 7 is hollow. The bottom surface of the expansion plate 7 is connected to a ventilation pipe 71 that passes through the bottom of the lower pressure cover 6. The top surface of the expansion plate 7 is provided with a negative pressure suction hole 72. A control component 8 that can drive the expansion plate 7 to move along the height direction of the lower pressure cover 6 is provided between the lower pressure cover 6 and the expansion plate 7.

[0054] Reference Figure 3 , Figure 6 and Figure 7 The control member 8 includes a guide tube 81, a sliding block 82, a sealing plate 83 and a tension spring 84. The guide tube 81 is fixedly connected to the top surface of the internal cavity of the expansion plate 7 and is coaxially arranged with the negative pressure suction hole 72. A gap is left between the bottom of the guide tube 81 and the bottom wall of the expansion plate 7. The sliding block 82 is slidably inserted into the guide tube 81 and a plurality of ventilation channels are provided on the sliding block 82. The sealing plate 83 is connected to the bottom surface of the sliding block 82 through a plurality of spaced support rods 85. The sealing plate 83 can seal the bottom pipe opening of the guide tube 81. The tension spring 84 is sleeved on the outer wall of the guide tube 81 and its two ends are respectively connected to the top surface of the internal cavity of the expansion plate 7 and the top surface of the sealing plate 83.

[0055] The air intake and air suction of the vent pipe 71 can make the expansion plate 7 and the negative pressure suction hole 72 have different states. When the external air intake device blows air into the vent pipe 71 and the internal cavity of the expansion plate 7, the sealing plate 83 seals the end of the guide tube 81 under the action of the tension spring 84. As the gas enters, the gas pushes the expansion plate 7 to move, so that the expansion plate 7 abuts against the upper cover plate, thereby achieving the purpose of flattening the upper cover plate. When the external air extraction device extracts the air inside the ventilation pipe 71 and the expansion plate 7, under the action of the gas pressure difference, the sliding block 82 and the sealing plate 83 move, so that a gap is left between the sealing plate 83 and the guide pipe 81, and a gap is left between the support rods 85. The air at the upper cover plate flows to the inside of the expansion plate 7 through the negative pressure suction hole 72, the inside of the guide pipe 81, the ventilation channel and the gap between the support rods 85, so that negative pressure suction is generated at the negative pressure suction hole 72, so that the upper cover plate is adsorbed on the expansion plate 7, so that the upper cover plate can be rotated with the rotation of the upper pressure cover 4, and the upper cover plate can be conveniently adjusted in orientation, so that the upper cover plate can be assembled with the lower cover plate. The purpose of streamlining the structure can be achieved and the structural footprint can be reduced.

[0056] Reference Figure 1 The conveyor belt 9 is placed on the assembly body 1 and is located below the assembly round table 3 for conveying the lower cover plate in sequence, so as to facilitate the automatic processing of the assembly line.

[0057] The implementation principle of an assembly device for a kit according to an embodiment of the present invention is as follows:

[0058] The cylinder 54 located at the loading point of the upper cover plate pushes the top of the moving rod 51, so that the moving rod 51 and the upper pressure cover 4 move downward. During the downward movement of the upper pressure cover 4, the first wedge block 28 and the second wedge block 29 at the bottom of the push rod 27 abut against each other, so that the sliding rod 24 and the loading plate 25 move. The loading plate 25 moves to the outside of the loading box 21, and the bottom of the upper pressure cover 4 matches the top surface of the upper cover plate. The multiple locking pins on the upper cover plate are inserted into the rubber ring 42 in a one-to-one corresponding manner. The assembled table 3 rotates, the moving rod 51 is separated from the output end of the cylinder 54, and the moving rod 51 moves upward under the action of the reset spring 52.

[0059] The sliding rod 24 moves under the action of the feeding spring 210, so that the feeding plate 25 is slidably inserted into the feeding groove 23, and the feeding plate 25 pushes the upper cover plate at the feeding groove 23 onto the receiving plate 26, so as to facilitate the feeding of the next upper pressure cover 4.

[0060] The rotating motor 62 controls the rotation of the lower pressure cover 6, and the lower pressure cover 6 cooperates with the upper pressure cover 4, and the upper cover plate is located between the upper pressure cover 4 and the lower pressure cover 6. Gas is blown into the inside of the expansion plate 7 through the vent pipe 71, and the sealing plate 83 seals the guide pipe 81 under the action of the tension spring 84, so that the expansion plate 7 slides, and the expansion plate 7 cooperates with the upper pressure cover 4 to flatten the upper cover plate, and the upper pressure cover 4 heats the upper cover plate to keep it flat.

[0061] Since the upper cover is relatively thin, after heating for a period of time, air is sucked in through the vent pipe 71. Under the action of the gas pressure difference, the sealing plate 83 is separated from the guide tube 81, and negative pressure suction is generated at the negative pressure suction hole 72, so that the lower pressure cover 6 adsorbs the upper cover. The rotating motor 62 controls the lower pressure cover 6 to rotate, and the upper cover rotates synchronously therewith, and the upper cover is cooled naturally.

[0062] As the assembly truncated table 3 rotates, the upper cover plate rotates to the unloading point, and the cylinder 54 at the unloading point pushes the moving rod 51, so that the upper cover plate matches the lower cover plate on the conveyor belt 9 and is assembled into a reagent kit, thereby completing the assembly.

[0063] The device is automatically assembled on the assembly line and the above steps are repeated.

[0064] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
