Detailed implementation manners

[0026] As Figures 1-3 shown, the present utility model provides a reaction cup storage and conveying structure, including a fixed plate 1, a turntable 2 rotatably arranged at the upper end of the fixed plate 1, a plurality of cup cylinders 3 annularly arranged at the upper end of the turntable 2, a cup leakage port arranged on the turntable 2 and corresponding to the lower end of the cup cylinder 3, cup-against elastic sheets 4 arranged at the lower end of the turntable 2 and on both sides of the cup leakage port, an upper cover 5 arranged at the upper end of the cup cylinder 3, a funnel assembly arranged at the upper end of the upper cover 5, a support frame arranged on the outer side of the cup cylinder 3, a cup storage driving motor 6 arranged on the support frame, and a gear 7 arranged at the output end of the cup storage driving motor 6. Tooth teeth are arranged on the outer periphery of the turntable 2, and the gear 7 meshes with the turntable 2. The cup storage driving motor 6 drives the gear 7 to drive the turntable 2 to rotate and drive the cup cylinders 3 to move annularly. An inlet cup port corresponding to the funnel assembly is arranged on the upper cover 5. The upper cover 5 and the side surface of the fixed plate 1 are fixed to the support frame. The upper cover 5 and the cup cylinder 3 are spaced up and down. The distance between the cup-against elastic sheets 4 is smaller than the inner diameter of the cup cylinder 3.

[0027] The reaction cup is placed at the inlet of the funnel assembly. Guided by the funnel assembly, it passes through the cup inlet of the upper cover 5 and falls into the cup cylinder 3 on the turntable 2. After the current cup cylinder 3 is filled with reaction cups, the cup storage drive motor 6 is started, and the drive gear 7 drives the turntable 2 to rotate, moving the turntable 2 to the cup inlet of the upper cover 5 for the next cup cylinder 3 to continue loading cups. The cup-retaining elastic piece 4 is an elastic metal piece. At both sides below the cup leakage opening corresponding to the lower end of each cup cylinder 3, cup-retaining elastic pieces 4 are symmetrically arranged. The opposite ends of the cup-retaining elastic pieces 4 are tightly pressed against the outer wall edge below the opening of the lowermost reaction cup in the current cup cylinder 3 to limit the reaction cup, preventing the reaction cups in the cup cylinder 3 from falling. This design greatly improves the cup storage capacity, has a high degree of automation, reduces a large amount of manual operation, and at the same time has a small volume and is convenient for loading cups.

[0028] As Figure 1 shown, the funnel assembly includes a cup inlet trough body 8 erected at the upper end of the upper cover 5, a baffle 9 arranged at the middle and lower openings of the cup inlet trough body 8, and a guiding inclined plate 10 arranged at the upper end of the baffle 9. The cup inlet trough body 8 has an opening facing outward, the guiding inclined plate 10 corresponds to the opening of the cup inlet trough body 8, and the upper end of the guiding inclined plate 10 is inclined in the direction away from the cup inlet trough body 8.

[0029] The cup inlet trough body 8 has upper and lower openings and an opening on one side facing outward, which is a through groove structure. The baffle 9 blocks the middle and lower parts of the outer opening of the cup inlet trough body 8, and the guiding inclined plate 10 guides when the reaction cup enters, facilitating the sliding of the reaction cup.

[0030] As Figures 1-2 shown, the support frame includes a left side plate 11 and a right side plate 12 arranged on both sides of the turntable 2. The left side plate 11 and the right side plate 12 are in a C-shaped structure. The cup cylinder 3 is arranged between the left side plate 11 and the right side plate 12. The upper cover 5 and the fixing plate 1 are respectively fixed to the inner sides of the left side plate 11 and the right side plate 12.

[0031] The upper cover 5, the left side plate 11, the right side plate 12, and the fixing plate 1 form the main support structure. The design of the C-shaped left side plate 11 and right side plate 12 can not only play a role in support and protection, but also facilitate the observation of the cup cylinder 3, and at the same time facilitate the assembly of the overall structure and the later maintenance and repair.

[0032] As Figures 4-6 shown, it further includes a cup-taking drive mechanism arranged on the support frame, a separation bracket 13 arranged on the support frame and outside the turntable 2, and a sliding top plate 14 slidably arranged on the separation bracket 13. On the opposite end faces of the sliding top plate 14, an upper cup-blocking plate 15 and a lower cup-blocking plate 16 are arranged at intervals up and down. The horizontal position of the cup-retaining elastic piece 4 is between the upper cup-blocking plate 15 and the lower cup-blocking plate 16. The sliding top plate 14 is driven by the cup-taking drive mechanism to have a degree of freedom of translating towards the cup-retaining elastic piece 4.

[0033] The separating bracket 13 is connected to the supporting bracket and serves as a carrier for supporting and limiting the sliding top plate 14. The sliding top plate 14 is slidably arranged on the sliding top plate 14 and can translate towards the cup-against elastic piece 4 under the drive of the cup-taking drive mechanism. The upper cup-blocking plate 15 corresponds to the position between the first reaction cup and the second reaction cup at the lowermost end in the current cup cylinder 3.

[0034] During operation, the two sliding top plates 14 translate towards the cup-against elastic piece 4 under the drive of the cup-taking drive mechanism, respectively pushing the two cup-against elastic pieces 4 outwards, and the upper cup-blocking plate 15 is inserted between the first reaction cup and the second reaction cup at the lowermost end in the front cup cylinder 3. The lowermost first reaction cup drops and overlaps on the lower cup-blocking plate 16, and the lower half of the lowermost second reaction cup is also inserted into the first reaction cup. Then, the sliding top plate 14 retracts. Since the lowermost first reaction cup is limited by the second reaction cup and will not translate synchronously with the sliding top plate 14, after the sliding top plate 14 is separated from the cup-against elastic piece 4, the lowermost first reaction cup automatically drops downwards, and the lowermost second reaction cup drops a certain distance and then re-abuts tightly on the cup-against elastic piece 4, thus completing the discharging of a single reaction cup. This design can accurately complete the discharging of a single reaction cup, with high automation, fast discharging speed, simple structure, more stable operation, and more convenient maintenance and repair.

[0035] As Figure 7 shown, it further includes a support piece 17 arranged at the upper end of the cup-against elastic piece 4. The cup-against elastic piece 4 is arranged horizontally. The support piece 17 is vertically fixed in the middle or on the outer side of the upper end of the cup-against elastic piece 4. One end of the support piece 17 facing the sliding top plate 14 is inclined outwards. The sliding top plate 14 corresponds to the inclined surface on the inner side of the support piece 17, and an avoidance notch 18 is arranged at one end of the sliding top plate 14 facing the support piece 17.

[0036] The support piece 17 is fixed at the upper end of the cup-against elastic piece 4. The support piece 17 is vertical and its outer end is inclined outwards. The inclined surface on the inner side corresponds to the sliding top plate 14. The sliding top plate 14 translates and abuts tightly on the inclined surface on the inner side of the support piece 17. After continuous translation, the support piece 17 is gradually pushed open, that is, the cup-against elastic piece 4 is pushed open, making the opening of the cup-against elastic piece 4 more stable, smoother, with less resistance. A chamfer is designed on the outer side of the end of the sliding top plate 14, making the process of the sliding top plate 14 abutting and pushing open smoother and more stable.

[0037] As Figures 8-9As shown, the cup-taking driving mechanism includes a bottom plate 19 fixed to the support frame and located below the fixed plate 1, a cup-taking driving motor 20 arranged at the lower end of the bottom plate 19, a driving disk 21 rotatably arranged at the upper end of the bottom plate 19 and in transmission connection with the cup-taking driving motor 20, a separation guide groove 22 arranged on the upper end surface of the driving disk 21, a separation translation plate 23 arranged at the upper end of the separation guide groove 22, a separation guide shaft 24 fixed on the separation translation plate 23 and extending into the separation guide groove 22, a first side limiting wheel 25 fixed to the lower end of the fixed plate 1 and located on both sides of the separation translation plate 23, a separation guiding long groove 26 arranged at the rear end of the separation translation plate 23, and a first rear limiting wheel 27 fixed to the lower end of the fixed plate 1 and located in the separation guiding long groove 26. The driving disk 21 is located between the fixed plate 1 and the bottom plate 19, the separation translation plate 23 is located between the fixed plate 1 and the driving disk 21. The front end of the separation translation plate 23 is connected to the sliding top plate 14. The separation translation plate 23 is limited by the first side limiting wheel 25 and the first rear limiting wheel 27. The driving motor drives the driving disk 21 to rotate. The rotation of the driving disk 21 drives the separation guide shaft 24 to move through the separation guide groove 22 and drives the separation translation plate 23 to translate.

[0038] Since the separation guide groove 22 is of an irregular shape and is difficult to describe in words, please refer to the attached drawings. And this shape is not unique as long as it can drive the separation translation plate 23 to translate. During operation, the cup-taking driving motor 20 drives the driving disk 21 to rotate. The first side limiting wheel 25 and the first rear limiting wheel 27 limit the separation translation plate 23, so that the separation translation plate 23 can only translate back and forth. When the driving disk 21 rotates, the separation guide shaft 24 moves under the guidance of the separation guide groove 22, synchronously driving the separation translation plate 23 to translate back and forth. The translation of the separation translation plate 23 synchronously drives the sliding top plate 14 to translate. The cup-taking driving motor 20 controls the forward and reverse rotation, and through the transmission of the driving disk 21, the separation guide groove 22, the separation guide shaft 2, and the separation translation plate 23, drives the sliding top plate 14 to translate back and forth. The structure is compact, the volume is small, the operation is stable, the automation degree is high, and the translation distance is easier to accurately control.

[0039] As Figures 10-11As shown in the figure, it further includes a push translation plate 28 provided at the lower end of the driving disk 21, a push guide groove 29 provided on the lower end face of the driving disk 21, a push guide shaft 30 provided at the upper end of the push translation plate 28 and inserted into the push guide groove 29, a push support 31 provided below the cup pressing elastic piece 4, side long slot holes 32 provided on both sides of the push translation plate 28, a second side limiting wheel 33 provided in the side long slot holes 32, a push guiding long slot 34 provided at the rear end of the push translation plate 28, and a second rear limiting wheel 35 provided in the push guiding long slot 34. The push translation plate 28 is located between the driving disk 21 and the bottom plate 19. The front end of the push translation plate 28 is connected to the push support 31. The upper end of the push support 31 corresponds to the leaking cup opening. The cup taking driving motor 20 drives the driving disk 21 to rotate. The rotation of the driving disk 21 drives the push guide shaft 30 to move through the push guide groove 29 and drives the push translation plate 28 to translate. The translation of the push translation plate 28 drives the push support 31 to translate.

[0040] Since the push guide groove 29 is of an irregular shape and difficult to describe in words, please refer to the attached drawings. And this shape is not unique as long as it can drive the push translation plate 28 to translate. After the lowest reaction cup drops, it will land on the push support 31. After the push support 31 translates, the single reaction cup is sent to the feeding station of the next process. During operation, the cup taking driving motor 20 drives the driving disk 21 to rotate. The push guide groove 29 on the lower end face of the driving disk 21 drives the push guide shaft 30 to move. The movement of the push guide shaft 30 drives the push translation plate 28 to move. The movement of the push translation plate 28 can only translate back and forth under the limitation of the second side limiting wheel 33 and the second rear limiting wheel 35. Moreover, the push guiding long slot 34 and the side long slot holes 32 limit the distance of the back-and-forth translation. The translation of the push translation plate 28 drives the push support 31 to translate. The reaction cup on the push support 31 is transported to the next station. This design is compact in structure, small in volume, stable and accurate in pushing. By using 1 cup taking driving motor 20 and the driving disk 21 in cooperation with different guide grooves, the separation and pushing of the reaction cups can be completed. The cup taking driving motor 20 rotates forward for separation and reverses for pushing. The structure is more compact, the volume is smaller, the operation is stable, the control is accurate, and the degree of automation is high.
