Description

Technical Field

[0001] The present invention relates to the technical field of automatic detection of reaction cups, and in particular to a full-automatic visual detection machine for reaction cups and a detection method thereof. Background Art

[0002] The reaction cup is a kind of test consumables used in the laboratory bacterial culture identification process. It is a product that uses the typical biochemical reaction characteristics of bacteria on this consumable to determine the bacterial genus. Figure 1 The figure shows a reaction cup 4 in the prior art, which includes a cup body 41 and a skirt 42 arranged radially outward along the cup body 41 .

[0003] In the factory, it is necessary to conduct appearance inspection on the processed reaction cups. For this purpose, workers need to manually compare the reaction cups to be inspected with standard reaction cups in an inspection room with specific brightness. The reaction cups to be inspected are compared manually with the naked eye. However, the manual visual inspection method is relatively cumbersome. Due to the differences in individual and ambient light, different people have different observation angles, operating habits and inspection standards. Since there is no unified standard, the comparison results of different comparison personnel are quite different. At the same time, both the loading process and the comparison process are very labor-intensive and need to be improved urgently. Summary of the invention

[0004] The object of the present invention is to provide a fully automatic visual inspection machine for a reaction cup and an inspection method thereof, which has the effects of automatic loading inspection, preventing scratches on the surface of the reaction cup, and high loading inspection efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A fully automatic visual inspection machine for reaction cups, comprising a loading device and a conveying and inspection device, the loading device comprising a first loading mechanism, a first clamping and conveying mechanism and a high-speed vibration feeding mechanism, the reaction cup conveyed by the first loading mechanism is conveyed to the high-speed vibration feeding mechanism through the first clamping and conveying mechanism, the first clamping and conveying mechanism comprises a first rotating roller and a second rotating roller arranged in parallel and rotating relatively, the outer walls of the first rotating roller and the second rotating roller are provided with a buffer and anti-scratch structure;

[0006] The conveying detection device includes a second clamping and conveying mechanism, an adsorption conveying mechanism, a material receiving mechanism, a material discharging mechanism and a plurality of visual inspection modules, wherein the high-speed vibration feeding mechanism is used to vibrate and convey the reaction cup to the second clamping and conveying mechanism, the adsorption conveying mechanism is used to adsorb the reaction cup from the second clamping and conveying mechanism and convey it to the material discharging mechanism, the material discharging mechanism includes a defective product discharging frame and a qualified product discharging frame, the material receiving mechanism is used to collect the reaction cups that are not adsorbed by the adsorption conveying mechanism and fall from the tail of the second clamping and conveying mechanism, the adsorption conveying mechanism and the material receiving mechanism are arranged at one end of the second clamping and conveying mechanism away from the high-speed vibration feeding mechanism, and the adsorption conveying mechanism is relatively arranged above the second clamping and conveying mechanism, and the material receiving mechanism is relatively arranged below the second clamping and conveying mechanism.

[0007] By adopting the above technical solution, the reaction cup to be tested is transported to the first clamping and conveying mechanism through the first feeding mechanism, and the skirt of the reaction cup is supported by the first rotating roller and the second rotating roller of the first clamping and conveying mechanism, so that the reaction cup is kept in a vertical state and conveyed to the high-speed vibration feeding mechanism. During the process of the first clamping and conveying mechanism transporting the reaction cup, the buffering and anti-scratch structure can effectively prevent the surface of the reaction cup from being scratched. Then, the reaction cup is vibrated and fed to the second clamping and conveying mechanism through the high-speed vibration feeding mechanism. While the second clamping and conveying mechanism is conveying the reaction cup, some visual inspection modules perform preliminary visual inspection on the reaction cup transported on the second clamping and conveying mechanism. When the reaction cup is transported to the second clamping and conveying mechanism, When the adsorbed reaction cups are at the end position of the adsorption conveying mechanism, some reaction cups are adsorbed onto the adsorption conveying mechanism and transported toward the discharging mechanism. During the transportation of the adsorbed reaction cups on the adsorption conveying mechanism, the remaining visual inspection modules are used to perform further visual inspection on the reaction cups, and further parameters of these reaction cups are measured and recorded. However, some reaction cups with surface defects are difficult to be adsorbed by the adsorption conveying mechanism. These defective reaction cups fall from the tail of the second clamping conveying mechanism and are collected by the receiving mechanism. Different from the low efficiency and different comparison results caused by traditional manual naked eye inspection, the present invention adopts fully automatic loading and conveying and automatic inspection by visual algorithm, which has the effects of automatic loading and inspection, prevention of scratches on the surface of the reaction cup, and high loading and inspection efficiency.

[0008] The present invention is further configured as follows: the first clamping and conveying mechanism includes a loading end close to the first loading mechanism and a blanking end close to the high-speed vibration feeding mechanism, the first rotating roller and the second rotating roller are arranged obliquely downward from the loading end toward the blanking end, a clamping gap is provided between the first rotating roller and the second rotating roller corresponding to the reaction cup, and the clamping gap gradually expands from the loading end toward the blanking end.

[0009] By adopting the above technical scheme, since the clamping gap between the first rotating roller and the second rotating roller gradually expands from the loading end to the blanking end, the first rotating roller and the second rotating roller will generate a driving force moving toward the blanking end when they rotate inward relative to each other, and the driving force drives the reaction cup to be transported from the loading end to the blanking end. When the reaction cup is transported to the blanking end, the clamping gap located on the blanking end side is larger than the skirt width of the reaction cup, and the reaction cup falls from the clamping gap of the blanking end to the high-speed vibration feeding mechanism by gravity. The first rotating roller and the second rotating roller of the present invention are arranged in an inclined manner, so that the reaction cup falling from the first loading mechanism into the clamping gap of the loading end of the first clamping and conveying mechanism can be more smoothly transported from the loading end to the blanking end under the cooperation of its own gravity and the driving action of the first rotating roller and the second rotating roller.

[0010] The present invention is further configured as follows: the first clamping and conveying mechanism includes a loading end close to the first loading mechanism and a blanking end close to the high-speed vibration loading mechanism, the first rotating roller and the second rotating roller are arranged in parallel and inclined downward from the loading end toward the blanking end, a clamping gap is provided between the first rotating roller and the second rotating roller corresponding to the reaction cup, and a blanking space connected to the clamping gap is provided on one side of the first rotating roller and the second rotating roller close to the blanking end.

[0011] By adopting the above technical solution, the reaction cup is transported from the loading end to the blanking end through the clamping gap between the first rotating roller and the second rotating roller. When the reaction cup is transported to the end of the blanking end, the reaction cup falls from the first rotating roller and the second rotating roller through the blanking space to realize blanking.

[0012] The present invention is further configured as follows: the buffer and anti-scratch structure is configured as a flexible rubber coating layer covering the first rotating roller and the second rotating roller.

[0013] By adopting the above technical solution, the flexible rubber coating layer can play a buffering role for the reaction cup transported on the first clamping and conveying mechanism, preventing the outer surfaces of the first rotating roller and the second rotating roller from directly and rigidly contacting the reaction cup when they rotate, thereby preventing the surface of the reaction cup from being scratched.

[0014] The present invention is further configured as follows: the first clamping and conveying mechanism includes a driving component, a driving gear and a driven gear, the driving component drives the first rotating roller to rotate, the driving gear is coaxially fixed to the first rotating roller, the driven gear is coaxially fixed to the second rotating roller, and the driving gear is meshed with the driven gear.

[0015] By adopting the above technical solution, the driving component drives the first rotating roller to rotate and then drives the driving gear to rotate. The driving gear then drives the second rotating roller to rotate through the driven gear. Under the meshing action of the driving gear and the driven gear, the first rotating roller and the second rotating roller always keep rotating in opposite directions.

[0016] The present invention is further configured as follows: the first clamping and conveying mechanism includes a guide structure arranged above the first rotating roller and the second rotating roller and below the first loading mechanism, the guide structure includes a plurality of guide plates arranged symmetrically and inclined downward, and the reaction cup falling from the first loading mechanism remains in a vertical state under the guiding action of the guide plates and falls onto the first clamping and conveying mechanism.

[0017] By adopting the above technical solution, under the guiding effect of the guide plates on both sides, it is ensured that each reaction cup dropped from the first loading mechanism can be turned over and kept in a vertical state to fall between the first rotating roller and the second rotating roller.

[0018] The present invention is further configured as follows: the second clamping and conveying mechanism includes a driving module, a first circular conveyor belt and a second circular conveyor belt arranged vertically in parallel, the driving module drives the first circular conveyor belt and the second circular conveyor belt to rotate relative to each other, and a clamping gap for clamping the reaction cup is provided between the first circular conveyor belt and the second circular conveyor belt.

[0019] By adopting the above technical solution, the reaction cup transported from the high-speed vibrating feeding mechanism is transported to the clamping gap between the first circular conveyor belt and the second circular conveyor belt, and the first circular conveyor belt and the second circular conveyor belt arranged vertically in parallel support the skirt of the reaction cup. At the same time, the driving module drives the first circular conveyor belt and the second circular conveyor belt to rotate relative to each other, thereby realizing the transportation of the clamped reaction cup on the second clamping and conveying mechanism.

[0020] The present invention is further configured as follows: the adsorption conveying mechanism comprises an annular adsorption conveying belt and a vacuum generating device, and an avoidance gap is left between the annular adsorption conveying belt and the first annular conveying belt and the second annular conveying belt.

[0021] By adopting the above technical solution, the negative pressure generated by the vacuum generating device acts on the annular adsorption conveyor belt, so that the reaction cup can be adsorbed on the annular adsorption conveyor belt for transportation.

[0022] The present invention is further configured as follows: the material receiving mechanism includes a material receiving frame, a track conveying module and a material unloading frame, the material receiving frame is arranged at one end of the first circular conveyor belt and the second circular conveyor belt close to the adsorption conveying mechanism, and the track conveying module is used to convey the reaction cups collected by the material receiving frame to the material unloading frame.

[0023] By adopting the above technical solution, the reaction cup dropped from the end of the second clamping and conveying mechanism is guided and slid onto the track conveying module through the receiving frame, and the track conveying module then conveys the reaction cup that has not been adsorbed to the unloading frame for unloading and collection.

[0025] S1: Loading: The cuvette to be tested is transported to the end of the first loading mechanism, and then falls from the end of the first loading mechanism onto the first clamping and conveying mechanism;

The flexible rubber layer can The reaction cup 4 transported on the first clamping and conveying mechanism 12 plays a buffering role, preventing the outer surfaces of the first rotating roller 121 and the second rotating roller 122 from directly and rigidly contacting the reaction cup 4 when rotating, resulting in the surface of the reaction cup 4 being scratched; the conveying and detecting device 2 is arranged on the chassis 3, and the conveying and detecting device 2 includes a second clamping and conveying mechanism 21, an adsorption conveying mechanism 22, a material receiving mechanism 23, a material discharging mechanism 24 and a plurality of visual detection modules, the high-speed vibration feeding mechanism 13 is used to vibrate and convey the reaction cup 4 to the second clamping and conveying mechanism 21, the adsorption conveying mechanism 22 is used to adsorb the reaction cup 4 from the second clamping and conveying mechanism 21 and convey it to the material discharging mechanism 24, and the material discharging mechanism 2 in this embodiment 4 includes a defective product discharging frame 241 and a qualified product discharging frame 242, wherein the defective product discharging frame 241 is used to discharge defective products, and the qualified product discharging frame 242 is used to discharge qualified products, and the receiving mechanism 23 is used to collect the reaction cups 4 that are not adsorbed by the adsorption conveying mechanism 22 and dropped from the tail of the second clamping conveying mechanism 21, and the adsorption conveying mechanism 22 and the receiving mechanism 23 are arranged at one end of the second clamping conveying mechanism 21 away from the high-speed vibration feeding mechanism 13, and the adsorption conveying mechanism 22 is relatively arranged above the second clamping conveying mechanism 21, and the receiving mechanism 23 is relatively arranged below the second clamping conveying mechanism 21; in this embodiment, the visual inspection module includes a first visual inspection module 2 51 and a plurality of second visual inspection modules 252, the first visual inspection module 251 is used for visual inspection of the reaction cup 4 on the second clamping and conveying mechanism 21, the second visual inspection module 252 is used for visual inspection of the reaction cup 4 on the adsorption and conveying mechanism 22, the first visual inspection module 251 is fixed on the sliding bracket 32, a damping guide rail 2511 is provided between the sliding bracket 32 ​​and the chassis 3, the sliding bracket 32 ​​is slidably arranged on the chassis 3 along the Y-axis direction through the damping guide rail 2511, when the first visual inspection module 251 is positioned correctly, the damping guide rail 2511 is threadedly locked by the locking piece 2512 on the sliding bracket 32, so that the sliding bracket 32 ​​and the chassis 3 remain fixed.

[0054] like Figure 6-8 As shown, the first clamping and conveying mechanism 12 includes a feeding end 12a close to the first feeding mechanism 11 and a blanking end 12b close to the high-speed vibration feeding mechanism 13.

The linear movement of the linear sliding module 26 can drive the second clamping and conveying mechanism 21 to move along the Y-axis direction on the chassis 3 to achieve position adjustment, which facilitates the alignment between the second clamping and conveying mechanism 21 and the adsorption and conveying mechanism 22, and ensures that the adsorption and conveying mechanism 22 can effectively adsorb the reaction cup 4 transported on the second clamping and conveying mechanism 21.

[0058] like Fig.12 and Fig.14As shown, the adsorption conveying mechanism 22 includes an annular adsorption conveying belt 221 and a vacuum generating device, and an avoidance gap is left between the annular adsorption conveying belt 221 and the first annular conveying belt 212 and the second annular conveying belt 213 in the height direction. The vacuum generating device is arranged in the annular adsorption conveying belt 221. The negative pressure generated by the vacuum generating device acts on the annular adsorption conveying belt 221, so that the reaction cup 4 can be adsorbed on the annular adsorption conveying belt 221 for transportation; a lifting module 31 is arranged between the chassis 3 and the adsorption conveying mechanism 22, and the lifting module 31 drives the adsorption conveying mechanism 22 to be lifted and lowered relative to the chassis 3 along the Z-axis direction. The lifting module 31 can adjust the height of the adsorption conveying mechanism 22 up and down, so that the adsorption conveying mechanism 22 can convey reaction cups 4 of different heights and sizes.

[0059] like Fig.12 and Fig.15 As shown, the material receiving mechanism 23 includes a material receiving frame 231, a track conveying module 232 and a material unloading frame 233. The material receiving frame 231 is arranged at one end of the first circular conveyor belt 212 and the second circular conveyor belt 213 close to the adsorption conveying mechanism 22. The track conveying module 232 is used to convey the reaction cup 4 collected by the material receiving frame 231 to the material unloading frame 233. The reaction cup 4 falling from the end of the second clamping conveying mechanism 21 is guided by the material receiving frame 231 and slides onto the track conveying module 232. The track conveying module 232 then conveys the reaction cup 4 that is not adsorbed to the material unloading frame 233 to realize material unloading and collection. The track conveying module 232 in this embodiment is arranged below the second clamping conveying mechanism 21, and the track conveying module 232 is arranged parallel to the conveying direction of the second clamping conveying mechanism 21.

[0060] The basic working principle of the present invention is as follows: the reaction cup 4 to be detected is transported from the hopper frame 111 to the horizontal conveying mechanism 113 through the ramp lifting loading mechanism 112, and then the reaction cup 4 falls from the end of the horizontal conveying mechanism 113. Under the guidance of the two side guide plates 126 on the first clamping and conveying mechanism 12, the reaction cup 4 remains in a vertical state and falls into the clamping gap 12c between the first rotating roller 121 and the second rotating roller 122 on the first clamping and conveying mechanism 12. The first rotating roller 121 and the second rotating roller 122 of the first clamping and conveying mechanism 12 are used to support the skirt 42 of the reaction cup 4. At the same time, the driving component 123 drives the first rotating roller 121 and the second rotating roller 122 to rotate inwardly relative to each other, and the reaction cup 4 is kept in a vertical state and conveyed to the high-speed vibration feeding mechanism 13. During the process of the first clamping and conveying mechanism 12 transporting the reaction cup 4, the buffering and anti-scratch structure can effectively prevent the surface of the reaction cup 4 from being scratched. Then, the reaction cup 4 is vibrated and loaded to the second clamping and conveying mechanism 13 by the high-speed vibration feeding mechanism 13. The second clamping and conveying mechanism 21 conveys the reaction cup 4, while some visual inspection modules perform preliminary visual inspection on the reaction cup 4 transported on the second clamping and conveying mechanism 21. When the reaction cup 4 is transported to the end position of the second clamping and conveying mechanism 21, some reaction cups 4 are adsorbed onto the adsorption and conveying mechanism 22 and transported toward the discharging mechanism 24. During the transportation of the adsorbed reaction cups 4 on the adsorption and conveying mechanism 22, the remaining visual inspection modules perform further visual inspection on the reaction cups 4, measure and record further parameters of these reaction cups 4, and some reaction cups 4 with surface defects are difficult to be adsorbed by the adsorption and conveying mechanism 22. These defective reaction cups 4 fall from the tail of the second clamping and conveying mechanism 21 and are collected by the receiving mechanism 23. Different from the low efficiency and different comparison results caused by traditional manual naked eye inspection, the present invention adopts a fully automatic feeding and conveying and a visual algorithm automatic detection method, which has the effects of automatic feeding and detection, preventing scratches on the surface of the reaction cup 4, and high feeding and detection efficiency.

[0061] Another technical purpose of the present invention is to provide a detection method of a reaction cup fully automatic visual inspection machine, comprising the following steps:

[0062] S1: Loading: The reaction cup to be tested is transported to the end of the first loading mechanism in a flat state and falls down. Under the guidance of the guide structure, the reaction cup is turned 90° and kept in a vertical state to fall onto the first clamping and conveying mechanism;

[0063] S2: Feeding: When the reaction cup falls onto the first clamping and conveying mechanism in a vertical state, the first rotating roller and the second rotating roller cooperate to support the skirt of the reaction cup. At the same time, under the action of the gravity of the reaction cup itself and the driving force generated when the first rotating roller and the second rotating roller rotate inward relative to each other and move toward the drop end, the reaction cup to be tested slides toward the high-speed vibration feeding mechanism along the inclined direction of the first rotating roller and the second rotating roller;

[0064] S3: high-speed feeding: when the reaction cup to be tested falls vertically from the tail ends of the first rotating roller and the second rotating roller, the reaction cup continues to maintain a vertical state and falls onto the high-speed vibration feeding mechanism, and the high-speed vibration feeding mechanism is used to feed the reaction cup to be tested onto the second clamping and conveying mechanism;

[0065] S4: Parallel conveying: When the reaction cup is conveyed to the second clamping conveying mechanism in a vertical state, the first and second ring conveying belts arranged in parallel are used to support the skirt of the reaction cup, and at the same time, the cup body of the reaction cup falls into the clamping gap between the first and second ring conveying belts for clamping, and the first and second ring conveying belts rotate relatively and convey the reaction cup toward the adsorption conveying mechanism;

[0066] S5: primary visual inspection: during the parallel conveying of the cuvette to be inspected by the second clamping and conveying mechanism, the first visual inspection module is used to perform a preliminary visual inspection on the cuvette;

[0067] S6: adsorption and conveying: when the reaction cup to be tested is conveyed to the end of the second clamping and conveying mechanism, the adsorption force generated by the adsorption and conveying mechanism is used to adsorb the reaction cup to be tested from the clamping gap of the second clamping and conveying mechanism to the adsorption and conveying mechanism, and the adsorption and conveying mechanism is used to adsorb and transport the reaction cup to be tested toward the direction of the discharging mechanism;

[0068] S7: receiving and collecting materials: some of the reaction cups conveyed by the second clamping and conveying mechanism are not adsorbed by the adsorption and conveying mechanism, and these reaction cups fall from the tail of the second clamping and conveying mechanism and are received and collected by the receiving mechanism;

[0069] S8: Secondary visual inspection: During the process of the adsorption and transportation mechanism adsorbing and transporting the reaction cup, the second visual inspection module performs further visual inspection on the reaction cup adsorbed on the adsorption and transportation mechanism. Specific embodiment 2

[0071] A fully automatic visual inspection machine for reaction cups, such as Fig.10As shown, the difference between this embodiment and the specific embodiment 1 is that: the first clamping and conveying mechanism 12 includes a feeding end 12a close to the first feeding mechanism 11 and a blanking end 12b close to the high-speed vibration feeding mechanism 13, the first rotating roller 121 and the second rotating roller 122 are arranged parallel and inclined downward from the feeding end 12a to the blanking end 12b, a clamping gap 12c is arranged between the first rotating roller 121 and the second rotating roller 122 corresponding to the reaction cup 4, and a blanking space 12d communicating with the clamping gap 12c is arranged on one side of the first rotating roller 121 and the second rotating roller 122 close to the blanking end 12b, the reaction cup 4 is conveyed from the feeding end 12a to the blanking end 12b through the clamping gap 12c between the first rotating roller 121 and the second rotating roller 122, and when the reaction cup 4 is conveyed to the end of the blanking end 12b, the reaction cup 4 falls from the first rotating roller 121 and the second rotating roller 122 through the blanking space 12d to achieve blanking.

[0072] The other structures of this embodiment are consistent with those of the first embodiment and will not be described again here.
