Description

Technical Field

[0001] The invention relates to the technical field of injection molding production technology, in particular to a balanced molding unloading detection device with self-sealing function to prevent material dropping. Background Art

[0002] The use of reaction cups is very extensive, including but not limited to biochemical tests, serum immunoassays, microbiological tests, blood and bone marrow tests, tissue section pathology tests, etc. These test items cover many aspects of medical tests. In addition, reaction cups are also used in the laboratory, which is an important place for various tests in medical laboratories. The use of reaction cups ensures the accuracy and efficiency of the test process.

[0003] In the production process of reaction cups, injection molding equipment is mostly used for manufacturing, and after the reaction cup is formed, a unloading detection device is required to remove the reaction cup from the injection molding equipment and conduct detection. Specifically, the injection molding equipment ejects the reaction cup, and then the unloading detection device adsorbs and transfers the reaction cup by generating negative pressure. In this process, the adsorption surface of the unloading detection device needs to be rotated 90° to achieve adsorption and release of the reaction cup. When the unloading detection device adsorbs the reaction cup, in order to prevent the reaction cup from deforming due to excessive negative pressure, the negative pressure intensity generated by the unloading detection device is generally slightly greater than the reaction cup's own gravity. This makes it easy for the reaction cup to fall off due to unstable adsorption when the adsorption surface of the unloading detection device is deflected, affecting the detection and transfer of the reaction cup.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0047] See also Figure 1 to Figure 10 In an embodiment of the present invention, a balanced molding unloading detection device with self-sealing function to prevent material from falling off is arranged at the side end of the injection molding equipment. Specifically, two sets of matching molds are arranged on the injection molding equipment. The two sets of molds are fitted to perform the injection molding action. After the reaction cup is formed, the reaction cup is attached to one of the sets of molds. At this time, the absorption arm plate 2 moves between the two sets of molds and makes the adsorption surface face the mold with the reaction cup attached, so that the unloading and transfer of the reaction cup can be realized. In this process, the injection molding equipment and the absorption arm plate 2 work together to improve the production speed of the reaction cup.

[0048] The anti-dropping self-sealing balanced molding unloading detection device comprises: a frame structure 1, a driving component, a suction hole 201, a suction component, a follower shaft 10 and a centrifugal component. When the absorption arm plate 2 performs a circular motion to switch positions, the sealing plug 24 moves away from the absorption arm plate 2 in the suction cylinder 22, thereby increasing the negative pressure in the suction hole 201, thereby improving the adsorption force of the suction hole 201 on the reaction cup, so that when the absorption arm plate 2 performs a circular motion, the connection force between the reaction cup and the suction hole 201 is stronger, thereby preventing the reaction cup from being separated from the absorption arm plate 2 due to the centrifugal force generated by the circular motion of the absorption arm plate 2. The details are as follows:

[0049] The frame structure 1 is provided with an absorption arm plate 2, and a grating detector 202 is provided on the absorption arm plate 2. The grating detector 202 is used to detect whether the heights of the reaction cups adsorbed by the absorption arm plate 2 are consistent. Furthermore, the absorption arm plate 2 is also provided with a negative pressure detection device (not shown in the figure), which is used to detect whether there is leakage on the absorption arm plate 2 or the reaction cup falls off;

[0050] The suction holes 201 are provided in multiple groups and are opened on the absorption arm plate 2;

[0051] The driving assembly is connected to the frame structure 1 and the absorption arm plate 2, and the driving assembly is used to drive the absorption arm plate 2 to move along the length direction of the frame structure 1, and can drive the absorption arm plate 2 to perform a swing action;

[0052] The driving assembly includes a beam frame 3 connected to the frame structure 1, a linear driving module 4 arranged along the length direction of the beam frame 3 is installed inside the beam frame 3, a connecting plate 5 is connected to the linear driving module 4, and the connecting plate 5 is rotatably connected to the absorption arm plate 2;

[0053] The driving assembly further comprises a rotating sleeve 6 rotatably mounted on the link plate 5, the rotating sleeve 6 being slidably fitted with a guide rod 7 fixedly mounted on the crossbeam frame 3, a fitting structure being provided between the guide rod 7 and the rotating sleeve 6, the fitting structure being capable of rotating the rotating sleeve 6 when the rotating sleeve 6 moves along the length direction of the guide rod 7, the fitting structure comprising a convex shaft 601 provided on the inner wall of the rotating sleeve 6 and a guide groove provided on the guide rod 7, the convex shaft 601 being capable of sliding along the length direction of the guide groove;

[0054] The guide groove comprises a spiral groove 702 spirally arranged along the axial direction of the guide rod 7, and the ends of the spiral groove 702 are provided with a first straight groove 701 and a second straight groove 703 along the length direction of the guide rod 7, and the first straight groove 701, the spiral groove 702 and the second straight groove 703 are connected;

[0055] The rotating sleeve 6 is connected to the rotating shaft of the absorption arm plate 2 via a connecting belt 8 .

[0056] In the initial state, the absorption arm plate 2 is in a state with the absorption surface facing downward. At this time, the absorption arm plate 2 can release the absorbed reaction cup into the corresponding collection bucket (shown in the figure). At the same time, in this state, the absorption arm plate 2 is misaligned with the injection molding equipment of the reaction cup, so as to avoid interference between the injection molding equipment and the absorption arm plate 2 when molding the reaction cup. In this state, the convex shaft 601 is at the end of the No. 1 straight groove 701 away from the No. 2 straight groove 703. At this time, the No. 1 straight groove 701 and the convex shaft 601 have the effect of axially positioning the absorption arm plate 2, thereby avoiding the shaking of the absorption arm plate 2 and causing the reaction cup to fall to the outside of the collection bucket when releasing the reaction cup.

[0057] After the injection molding equipment completes the molding of the reaction cup, the linear drive module 4 can drive the connecting plate 5 to move along the length direction of the guide rod 7, and when the convex shaft 601 moves along the No. 1 straight groove 701 to the spiral groove 702, the rotating sleeve 6 will rotate and drive the rotating shaft of the absorption arm plate 2 to rotate through the connecting belt 8. When the convex shaft 601 moves to the end of the spiral groove 702, the absorption arm plate 2 just rotates 90°, so that the adsorption surface of the absorption arm plate 2 is perpendicular to the plumb plane, and then the convex shaft 601 moves along the No. 2 straight groove 703, so that the absorption arm plate 2 maintains the state of the adsorption surface perpendicular to the plumb plane and enters the injection molding equipment, and when the absorption arm plate 2 is in place, the injection molding equipment pushes the reaction cup out and uses the negative pressure detection device to make the suction hole 201 generate suction to adsorb the reaction cup.

[0058] Through the above arrangement, on the one hand, the horizontal position of the absorption arm plate 2 can be switched, so that it can be misaligned with the injection molding equipment to prevent interference between the absorption arm plate 2 and the injection molding equipment. On the other hand, the convex shaft 601 can realize the deflection of the absorption arm plate 2 by cooperating with the No. 1 straight groove 701, the spiral groove 702 and the No. 2 straight groove 703, so that the absorption arm plate 2 can have two position states of adsorbing the reaction cup and releasing the reaction cup, simplifying the equipment structure, and when the convex shaft 601 cooperates with the No. 1 straight groove 701 and the No. 2 straight groove 703, the axial locking of the absorption arm plate 2 can be realized, thereby improving the directional stability of the absorption arm plate 2, making it more stable when adsorbing and releasing the reaction cup.

[0059] See also Figure 3 , Figure 7 , Fig. 9 The suction assembly is arranged on the absorption arm plate 2 and is connected to the suction hole 201. The suction assembly can increase the negative pressure intensity in the suction hole 201 when the absorption arm plate 2 is deflected;

[0060] The suction assembly includes a suction cylinder 22 fixedly mounted on the absorption arm plate 2 and a cover 26 connected to the suction hole 201, and the cover 26 is connected to the interior of the suction cylinder 22 through a conduit 25;

[0061] A sealing plug 24 is also sealed and slidably installed in the suction cylinder 22, and a connecting shaft 23 that is slidably arranged and passes through the suction cylinder 22 is fixedly installed on the sealing plug 24. The connecting shaft 23 is connected to the centrifugal assembly through a pushing structure, and the pushing structure includes a driving plate 21 connected to an end of the connecting shaft 23 away from the sealing plug 24, and a connecting rod 19 connected to the centrifugal assembly. A groove wheel 20 is rotatably installed on the connecting rod 19, and an inclined groove 2101 is provided on the driving plate 21. The groove wheel 20 cooperates with the inclined groove 2101, so that the driving plate 21 can drive the sealing plug 24 to slide in the suction cylinder 22 through the connecting shaft 23.

[0062] When the convex shaft 601 cooperates with the spiral groove 702, the absorption arm plate 2 will deflect along its rotation axis and switch the position state. At this time, the follower shaft 10 can follow the absorption arm plate 2 to make a circular motion and rotate under the action of the toothed structure. When the follower shaft 10 rotates, the centrifugal assembly connected thereto will move and push the connecting rod 19 to move toward the outside of the follower shaft 10. In this process, the groove wheel 20 cooperates with the inclined groove 2101 to enable the driving plate 21 to move upward, and drive the sealing plug 24 to move away through the connecting shaft 23. The absorption arm plate 2 moves away from the suction cylinder 22, so that negative pressure is generated in the suction cylinder 22. At this time, the conduit 25, the cover 26 and the suction hole 201 are all in a negative pressure state, which can increase the intensity of the negative pressure generated by the original negative pressure detection device to adsorb the reaction cup, so that the reaction cup has higher stability when following the absorption arm plate 2 to make a circular motion, avoiding the reaction cup from being separated from the suction hole 201 due to centrifugal force, and because the reaction cup fits the suction hole 201, the reaction cup has the effect of blocking the suction hole 201, avoiding the gap between the two and causing pressure loss.

[0063] Furthermore, after the absorption arm plate 2 is deflected into place, the centrifugal assembly will stop working, and the negative pressure state in the suction hole 201 can be restored to the initial state, that is, only the negative pressure detection device generates negative pressure, thereby avoiding deformation of the reaction cup caused by long-term and large negative pressure state.

[0064] Through the above arrangement, when the absorption arm plate 2 makes a circular motion to switch positions, the sealing plug 24 can move away from the absorption arm plate 2 in the suction cylinder 22, thereby increasing the negative pressure in the suction hole 201 and improving the adsorption force of the suction hole 201 on the reaction cup. When the absorption arm plate 2 makes a circular motion, the connection force between the reaction cup and the suction hole 201 is stronger, thereby avoiding the separation of the reaction cup and the absorption arm plate 2 due to the centrifugal force generated by the circular motion of the absorption arm plate 2.

[0065] See also Figure 3 , Figure 7~Figure 9 The follower shaft 10 is rotatably mounted on the absorption arm plate 2, and the follower shaft 10 is connected to a toothing structure provided on the driving assembly, and the toothing structure includes a gear 11 coaxially fixedly connected to the end of the follower shaft 10 and a gear ring 12 fixedly mounted on the connecting plate 5, and a plurality of teeth are equidistantly arranged on the inner side of the gear ring 12, and the teeth are meshed with the gear 11;

[0066] The centrifugal assembly is connected to the follower shaft 10 and the suction assembly. The centrifugal assembly can drive the connecting rod 19 to move when the absorption arm plate 2 deflects. The absorption arm plate 2 is provided with a vertical plate 9. The follower shaft 10 is rotatably mounted on the vertical plate 9. The interior of the follower shaft 10 is a hollow structure. The connecting rod 19 is inserted into the follower shaft 10.

[0067] The centrifugal assembly comprises a plurality of rotating members 15 equidistantly arranged on the follower shaft 10, the rotating member 15 is provided with a slide groove 1501 along its length direction, a slider 16 is slidably installed in the slide groove 1501, a counterweight block 17 is arranged at one end of the slider 16, and a pulling rod 14 is rotatably installed at one end of the slider 16;

[0068] The centrifugal assembly further comprises a follower sleeve 13 slidably mounted on the follower shaft 10, the follower sleeve 13 is connected to the connecting rod 19, and the follower sleeve 13 is rotatably connected to an end of the pulling rod 14 away from the slider 16;

[0069] The follower shaft 10 is also sleeved with a No. 1 spring 18 , one end of the No. 1 spring 18 is connected to the follower sleeve 13 , and the other end of the No. 1 spring 18 is connected to the rotating member 15 .

[0070] When the absorption arm plate 2 makes a circular motion, the follower shaft 10 can make a circular motion, and the gear 11 can make a circular motion. When the gear 11 makes a circular motion, the gear 11 meshes with the teeth on the gear ring 12 and rotates. At this time, the follower shaft 10 can drive the rotating part 15 to rotate, so that the slider 16 and the counterweight block 17 make a circular motion and generate centrifugal force. Under the action of the centrifugal force, the slider 16 pulls the follower sleeve 13 toward the rotating part 15 through the pulling rod 14, compressing the No. 1 spring 18 while causing the connecting rod 19 to move to drive the sealing plug 24 to move, thereby generating negative pressure, that is, the generation of negative pressure is synchronized with the deflection of the absorption arm plate 2, thereby improving the coordination between the two actions and avoiding delays between the two actions.

[0071] See also Figure 7 , Fig.10 , a balanced forming unloading detection device with self-sealing function to prevent material dropping, further comprising:

[0072] An adjusting tube body 27 connected to the suction cylinder body 22, wherein a convex ring 2701 is arranged in the adjusting tube body 27, and a blocking member 28 arranged in the adjusting tube body 27 is adapted to the convex ring 2701;

[0073] A connecting column 29 is arranged on the sealing member 28 and slidably connected to the adjusting tube body 27, and a No. 2 spring 30 is sleeved on the connecting column 29. One end of the No. 2 spring 30 is connected to the sealing member 28, and the other end is connected to an adjusting structure arranged in the adjusting tube body 27. The adjusting structure includes an adjusting ring 31 connected to the other end of the No. 2 spring 30, and a vertical shaft 32 slidably connected to the adjusting tube body 27 is connected to the adjusting ring 31. A threaded sleeve 33 is arranged at one end of the vertical shaft 32 away from the adjusting ring 31, and the threaded sleeve 33 is threadedly matched with a threaded rod 34 rotatably mounted on the adjusting tube body 27.

[0074] When negative pressure is generated in the suction hole 201, its negative pressure value is the same as the negative pressure value in the suction cylinder 22. If the deflection speed of the absorption arm plate 2 is too fast or the thickness of the reaction cup is thin, the excessive negative pressure value in the suction hole 201 will cause the reaction cup to deform. At this time, under the action of negative pressure, the sealing member 28 can move away from the convex ring 2701, compressing the No. 2 spring 30 while making the adjustment tube body 27 conductive. At this time, the pressure relief action can be performed to avoid deformation of the reaction cup caused by excessive negative pressure.

[0075] By rotating the threaded rod 34, the position of the threaded sleeve 33 can be changed. At this time, the position of the adjusting ring 31 can be changed, so that in the initial state, one end of the No. 2 spring 30 can be compressed or released, thereby changing the negative pressure intensity in the suction hole 201 when the sealing member 28 is actuated.

[0076] Through the above arrangement, the negative pressure strength in the suction hole 201 when the blocking member 28 is in action can be changed according to production needs, so as to avoid deformation of the reaction cup due to excessive negative pressure strength when the absorption arm plate 2 swings too fast or the reaction cup is thin, thereby improving the production process quality.
