Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of in-vitro diagnosis, in particular to a positive and negative marking device and a freeze-dried ball implantation equipment. BACKGROUND

[0002] In the process of in-vitro diagnosis, biological samples (such as blood, urine or tissue, etc.) are usually dropped into a microfluidic disc for testing to obtain diagnostic information. Before testing with the microfluidic disc, the testing reagent can be freeze-dried to form a freeze-dried ball, and the freeze-dried ball can be implanted into the disc hole on the microfluidic disc. The freeze-dried testing reagent can be stably stored at room temperature, which not only prolongs the shelf life of the testing reagent and reduces the transportation and storage costs of the testing reagent, but also greatly simplifies the testing operation process by directly adding biological samples to the microfluidic disc when testing is needed. After implanting the freeze-dried ball into the microfluidic disc, the microfluidic disc can be labeled to mark the specific information of the microfluidic disc.

[0003] However, the current marking device can only label the front of the microfluidic disc. If the back of the microfluidic disc needs to be labeled, the microfluidic disc needs to be manually flipped over before the back can be labeled. Thus, the process of manually flipping the microfluidic disc is time-consuming and inefficient, which slows down the entire production process, especially when a large number of microfluidic discs need to be labeled on the back, which greatly affects the speed and efficiency of labeling the microfluidic disc.

Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative labor shall fall within the scope of protection of the present application.

[0025] In the following description, a large number of details are provided so that the present application can be thoroughly understood. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0026] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can also have other embodiments.

[0027] In an embodiment of the present application, a forward and reverse marking device is provided, which can quickly and conveniently turn over the material, so that the marking assembly 3 can mark the front and back of the material. In the following, a forward and reverse marking device according to an embodiment of the present application will be described in detail with reference to the drawings.

[0028] As shown in Figure 1 The forward and reverse marking device is used for marking the front and / or back of the material conveyed on the production line, and the forward and reverse marking device comprises two marking assemblies 3, a synchronous moving assembly 2 and two turning assemblies 1. The two marking assemblies 3 each have a marking position. The synchronous moving assembly 2 is connected with the two turning assemblies 1, and the two turning assemblies 1 are used to simultaneously reach the initial positions 11 close to each other and simultaneously reach the two marking positions 12 of the two marking assemblies 3 away from each other under the action of the synchronous moving assembly 2. The turning assembly 1 has a carrier 13 for carrying the material; and the turning assembly 1 can obtain the material from the production line and turn over the material to expose the back of the material.

[0029] The two marking assemblies 3 can mark the materials located at the two marking positions 12 respectively, thereby improving the marking efficiency of the front and back marking device.

[0030] The initial position 11 can represent the position of the turnover assembly 1 when the turnover assembly 1 does not carry the material to be turned over, and the marking position 12 can represent the position of the turnover assembly 1 when the turnover assembly 1 carries the material to be turned over. When the front of the material is marked, the turnover assembly 1 can be located at the initial position 11 to avoid interfering with the marking operation. When the back of the material needs to be marked, the turnover assembly 1 can move to the marking position 12 and move in the vertical direction to pick up the material, and after picking up the material, the turnover assembly 1 can carry the material to be turned over to expose the back of the material.

[0031] The synchronous moving assembly 2 can be arranged between the two turnover assemblies 1, and the synchronous moving assembly 2 can drive the two turnover assemblies 1 to move simultaneously from the initial position 11 to the marking position 12 or from the marking position 12 to the initial position 11.

[0032] The front and back marking device can further include a sliding groove 6, two ends of the sliding groove 6 can be arranged correspondingly at the initial position 11 and the marking position 12, and the turnover assembly 1 can be connected with the sliding groove 6 in a sliding manner and reciprocate along the sliding groove 6 between the initial position 11 and the marking position 12.

[0033] The front and back marking device of the utility model, the synchronous moving assembly 2 can drive the two turnover assemblies 1 to reciprocate simultaneously between the initial position 11 and the marking position 12, when the turnover assembly 1 moves to the marking position 12, the turnover assembly 1 can pick up the material on the production line and carry the material to do the turnover movement, thereby the back of the material can be turned upward, and then the marking assembly 3 can be used to mark the front and / or back of the material, in this way, the time required for turning over the material is greatly reduced, and the marking speed and efficiency of the material are effectively improved. Moreover, one synchronous moving assembly 2 can be used to drive the movement of the two turnover assemblies 1 simultaneously, the mechanical connection structure of the front and back marking device is effectively simplified, and the manufacturing cost of the front and back marking device is reduced.

[0034] In some embodiments, as shown in Figure 1 The turnover assembly 1 further includes a fixed seat 14 and a first driving member (not shown in the figure) connected with the carrier 13, the carrier 13 is connected with the fixed seat 14 in a sliding manner through a sliding rail 15, and the first driving member is used to drive the carrier 13 to move along the length direction of the sliding rail 15.

[0035] The fixed seat 14 can provide a supporting force for the carrier 13, the slide rail 15 can be arranged on the fixed seat 14 in the vertical direction, and the first driving member can drive the carrier 13 to move along the slide rail 15, so that the carrier 13 can reciprocate in the vertical direction to obtain materials.

[0036] The first driving member can be a cylinder or other device capable of driving the carrier 13 to move, and the application does not limit the type of the first driving member.

[0037] In the above embodiment, the first driving member can drive the carrier 13 to slide along the slide rail 15, thereby effectively simplifying the structure of the turnover assembly 1 and reducing the manufacturing cost of the turnover assembly 1 while ensuring that the turnover assembly 1 can reciprocate in the vertical direction.

[0038] In some embodiments, as shown in Figure 1 The turnover assembly 1 includes a second driving member 16 and a first synchronous belt 17 connected to the second driving member 16, each turnover assembly 1 has two carriers 13 arranged side by side, and each carrier 13 is connected to a corresponding rotating wheel 18, the first synchronous belt 17 is arranged outside the two rotating wheels 18, and the second driving member 16 is used to drive the two rotating wheels 18 to rotate through the first synchronous belt 17 to drive the two carriers 13 to rotate synchronously.

[0039] The two carriers 13 can be arranged side by side in the horizontal direction, and each end of the two carriers 13 close to the fixed seat 14 can be connected to a rotating wheel 18, and the second driving member 16 can drive the rotating wheel 18 to rotate through the first synchronous belt 17. Specifically, when the second driving member 16 drives the first synchronous belt 17 to move in a straight line, the first synchronous belt 17 can simultaneously drive the two rotating wheels 18 to rotate circumferentially, so that the linear motion of the first synchronous belt 17 can be converted into the circumferential rotation of the rotating wheel 18, thereby realizing the synchronous turnover of the two carriers 13.

[0040] The second driving member 16 can be a cylinder, which can drive the first synchronous belt 17 connected thereto to move in a straight line during extension and contraction. Of course, the second driving member 16 can also be other devices capable of driving the first synchronous belt 17 to move in a straight line, and the application does not limit the type of the second driving member 16.

[0041] In the above embodiment, through the cooperation of the first synchronous belt 17 and the rotating wheel 18, the linear motion of the first synchronous belt 17 can be converted into the circumferential rotation of the rotating wheel 18, so as to realize the overturning of the carrier 13 connected with the rotating wheel 18. Not only the structure of the overturning assembly 1 is simplified, and the manufacturing cost of the overturning assembly 1 is reduced, but also the two carriers 13 of one overturning assembly 1 can be overturned synchronously, which effectively improves the overturning efficiency of the overturning assembly 1. Moreover, the two overturning assemblies 1 are independently arranged, so that the carriers 13 of the two overturning assemblies 1 can be freely overturned under the common driving of the second driving member 16, the first synchronous belt 17 and the rotating wheel 18 corresponding thereto according to the actual use condition, which effectively improves the overturning efficiency and practicability of the positive and negative marking device.

[0042] In some embodiments, as shown in Figure 1 The synchronous moving assembly 2 includes a third driving member 21, a second synchronous belt 22 and a synchronous wheel set 23. The second synchronous belt 22 is sleeved outside the synchronous wheel set 23. The two overturning assemblies 1 are connected with the second synchronous belt 22. The third driving member 21 is used to drive the synchronous wheel set 23 to rotate, so as to drive the two overturning assemblies 1 to reciprocate between the initial position 11 and the marking position 12 through the second synchronous belt 22.

[0043] In the above embodiment, the third driving member 21 can drive the synchronous wheel set 23 to rotate in the clockwise direction or the counterclockwise direction. The second synchronous belt 22 can be sleeved outside the synchronous wheel set 23, so as to convert the circumferential rotation of the synchronous wheel set 23 into the linear motion of the second synchronous belt 22, and further drive the two overturning assemblies 1 to reciprocate between the initial position 11 and the marking position 12. In this way, one third driving member 21 can drive the two overturning assemblies 1 to move synchronously, which simplifies the mechanical connection structure of the synchronous moving assembly 2, reduces the number of third driving members 21, reduces the manufacturing cost, increases the number of materials that can be overturned at the same time, and further improves the overturning efficiency of the positive and negative marking device.

[0044] In some embodiments, as shown in Figure 1As shown, the synchronous wheel set 23 comprises a driving wheel 231 and two driven wheels 232, the driving wheel 231 is connected with the third driving member 21, the two driven wheels 232 are respectively arranged near the marking positions 12 of the two turnover assemblies 1, the second synchronous belt 22 is sleeved outside the driving wheel 231 and the two driven wheels 232, the second synchronous belt 22 has a first part 221 and a second part 222 connected with each other, the two turnover assemblies 1 are respectively connected with the first part 221 and the second part 222, when the third driving member 21 drives the driving wheel 231 to rotate, the first part 221 is used to drive the turnover assembly 1 connected therewith to move in a first direction, and the second part 222 is used to drive the turnover assembly 1 connected therewith to move in a second direction, the first direction and the second direction are opposite.

[0045] The third driving member 21 can be connected with the driving wheel 231 through a rotating shaft, and drives the driving wheel 231 to rotate in a clockwise direction or a counterclockwise direction. The two driven wheels 232 are respectively arranged near the marking positions 12 of the two turnover assemblies 1, so that the second synchronous belt 22 can drive the turnover assemblies 1 to move between the initial positions 11 and the marking positions 12.

[0046] The first direction and the second direction can respectively represent movement directions opposite to each other along an X-axis in a Cartesian coordinate system. For example, when the first direction specifically represents a movement direction to the right, the second direction can represent a movement direction to the left. It can be understood that when the first direction specifically represents a movement direction to the left, the second direction can represent a movement direction to the right.

[0047] One turnover assembly 1 can be clamped on the first part 221 of the second synchronous belt 22 through the first clamping plate 7, and the other turnover assembly 1 can be clamped on the second part 222 of the second synchronous belt 22 through the second clamping plate 8. Specifically, as shown, Figure 1 When the third driving member 21 drives the driving wheel 231 to rotate clockwise, the first part 221 can move to the right under the driving of the driving wheel 231 and the driven wheels 232, and at the same time, the second part 222 can move to the left under the driving of the driving wheel 231 and the driven wheels 232. Conversely, when the third driving member 21 drives the driving wheel 231 to rotate counterclockwise, the first part 221 can move to the left under the driving of the driving wheel 231 and the driven wheels 232, and at the same time, the second part 222 can move to the right under the driving of the driving wheel 231 and the driven wheels 232. In this way, the two turnover assemblies 1 connected with the first part 221 and the second part 222 respectively move away from or close to each other.

[0048] The synchronous wheel set 23 can further include a tensioning wheel 233, the second synchronous belt 22 can be sleeved outside the driving wheel 231, the driven wheel 232 and the tensioning wheel 233, the tensioning wheel 233 can be used to adjust the tightness of the second synchronous belt 22, so as to reduce the vibration generated when the second synchronous belt 22 runs, and also can prevent the second synchronous belt 22 from slipping, effectively ensuring the stable movement of the second synchronous belt 22.

[0049] In the above embodiment, the circumferential rotation of the driving wheel 231 and the driven wheel 232 can be converted into the linear motion of the second synchronous belt 22, and then the two turnover assemblies 1 connected with the second synchronous belt 22 can be driven to move close to or away from each other through the second synchronous belt 22, further simplifying the mechanical connection structure of the synchronous movement assembly 2 and reducing the manufacturing cost of the synchronous movement assembly 2.

[0050] In some embodiments, as shown in Figure 1 The platform 13 is provided with suction accessories 131, which are used to apply suction force to the material to make the material turn over with the platform 13.

[0051] When the platform 13 drives the suction accessories 131 to move in the vertically downward direction and abuts against the material, the suction accessories 131 can apply suction force to the material to adsorb the material on the suction accessories 131. When the platform 13 moves in the vertically upward direction and drives the suction accessories 131 and the material on the suction accessories 131 to turn over, the suction accessories 131 can continuously apply suction force to the material to firmly limit the material on the suction accessories 131.

[0052] The suction accessories 131 can be suction cups. By using the suction cups to adsorb the material, the damage to the surface of the material can be avoided, which is especially suitable for fragile or surface-keeping objects such as glass or plastic.

[0053] In the above embodiment, the suction accessories 131 can adsorb the material and make the material turn over with the platform 13. The suction accessories 131 not only can provide stable suction force to avoid the material from falling when turning over with the platform 13, but also can protect the outer surface of the material to reduce the damage to the material. In addition, the suction accessories 131 can adsorb materials of different shapes and sizes, thereby having good adaptability and effectively improving the practicality and adaptability of the positive and negative marking device.

[0054] In some embodiments, as shown in Figure 1 The suction accessories 131 are multiple, and the multiple suction accessories 131 are distributed in multiple rows and multiple columns.

[0055] The platform 13 can be in the shape of a long strip, and the long strip-shaped platform 13 can be provided with multiple suction accessories 131 at intervals.

[0056] In the above embodiment, the plurality of suction accessories 131 can simultaneously obtain a plurality of materials and simultaneously drive the plurality of materials to perform the overturning movement, thereby effectively improving the carrying capacity of the carrier 13 and further improving the overturning efficiency of the forward and reverse marking device.

[0057] In some embodiments, as shown in Figure 2 The two marking assemblies 3 are respectively arranged at two opposite outer sides of the initial positions 11 of the two overturning assemblies 1.

[0058] In the above embodiment, the two marking assemblies 3 are respectively arranged at two opposite outer sides of the initial positions 11 of the two overturning assemblies 1, so that when the two marking assemblies 3 perform the marking operation on the front surface of the material, the two overturning assemblies 1 can be respectively located at the initial positions 11 to avoid interference between the overturning assembly 1 and the marking assembly 3, thereby affecting the marking operation of the marking assembly 3, and effectively improving the layout rationality of the forward and reverse marking device.

[0059] In some embodiments, as shown in Figure 2 The forward and reverse marking device further comprises a conveying member 4 and a transfer member (not shown in the figure), the conveying member 4 is used to convey the carrier 5 containing the material to the marking assembly 3, and the transfer member is used to transfer the carrier 5 on the conveying member 4 after the marking assembly 3 completes the marking operation.

[0060] The conveying member 4 can be a conveying belt, which can drive the carrier 5 to move along the length direction of the conveying belt to convey the carrier 5 to the marking assembly 3.

[0061] A plurality of materials can be placed on the carrier 5, and after the marking operation on the materials on the carrier 5 is completed, the transfer member can carry the carrier 5 on the conveying member 4 to facilitate subsequent operation of the materials. The transfer member can be a movable clamping jaw or a movable supporting plate, and the type of the transfer member is not limited in the application.

[0062] In the above embodiment, through the cooperation of the conveying member 4 and the transfer member, the forward and reverse marking device can have a wider use scene and a wider use range, thereby greatly improving the practicability of the forward and reverse marking device.

[0063] According to one aspect of the application, a freeze-dried ball implanting device is also provided, which comprises an implanting device, a film pasting device, and the forward and reverse marking device as described above. The implanting device and the film pasting device are sequentially arranged upstream of the forward and reverse marking device.

The implanting device can be used to implant freeze-dried balls into the disc holes of the microfluidic disc, and the film pasting device can be used to perform the film pasting operation on the microfluidic disc after the freeze-dried balls are implanted, so as to protect the microfluidic disc.
