Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic glue dispensing and curing device for an injection needle. Background Art

[0002] Injection needles (such as hyaluronic acid needles) need to go through the processes of glue dispensing and curing during the production process. The two processes are currently mostly completed manually and separately. That is, the commonly used method is to first manually use a syringe to dispense photosensitive glue on the needle seat and the connection between the needle tube of the injection needle, and then transfer the injection needle that has completed the glue dispensing process to a light curing furnace for light curing. However, the existing processing methods have the following shortcomings:

[0003] First, due to the manual dispensing process, the syringe needle is likely to touch the needle of the injection needle during the dispensing process, which may cause the photosensitive adhesive to block the needle of the injection needle, resulting in unqualified injection needles.

[0004] Second, when the injection needle after the dispensing process is transferred to the light curing furnace, the water is not solidified, which can easily affect the relative position between the needle seat and the needle tube of the injection needle, thereby affecting the assembly of subsequent products and making the needle tip of the needle tube easily deformed;

[0005] Third, mass production requires hiring a large number of workers, resulting in high production costs.

[0006] In order to solve the shortcomings of the existing injection needle dispensing and curing processing, an automatic dispensing and curing device for injection needles has been developed to realize the automatic dispensing and curing processing of injection needles. The automatic dispensing and curing device for injection needles can improve the qualified rate and processing efficiency of dispensing and curing of injection needles, reduce production costs, and meet mass production requirements; however, the shortcomings of the existing automatic dispensing and curing device for injection needles are:

[0007] After each dispensing, the photosensitive glue remaining in the dispensing head will overflow, and the overflowed photosensitive glue will affect the next dispensing process, which may easily cause the produced injection needles to be unqualified; and the overflowed photosensitive glue also has the risk of dripping, which may not only pollute the surrounding working environment, but also contaminate the injection needles and increase the unqualified rate of injection needles. Summary of the invention

[0008] In order to solve the above problems, the main purpose of the utility model is to provide an automatic dispensing and curing device for injection needles that can improve product quality and increase product qualification rate.

[0009] In order to achieve the main purpose of the utility model, the utility model provides an automatic dispensing and curing device for an injection needle, including a material moving unit, a dispensing unit and a light curing unit, the material moving unit includes a first driving mechanism and a movable seat, the driving mechanism can drive the movable seat to move between a dispensing position and a curing position, the dispensing unit is arranged at the dispensing position, the dispensing unit includes a second driving mechanism and a dispensing head, the light curing unit is arranged at the curing position, wherein the automatic dispensing and curing device for an injection needle also includes a clamp and a wiping unit, the clamp is installed on the movable seat, the clamp has a accommodating position, the second driving mechanism can drive the dispensing head to move relative to the accommodating position, the wiping unit includes a wiping piece, and the second driving mechanism can also drive the dispensing head to move to the wiping piece.

[0010] As can be seen from the above, before each round of dispensing operation in the dispensing unit, the second driving mechanism drives the dispensing head to move to the wiping piece to absorb the photosensitive glue overflowing from the dispensing head and wipe and clean the needle tube of the dispensing head to prevent the overflowed photosensitive glue from dripping onto the processed injection needle, thereby causing the injection needle to be contaminated and / or the needle tube of the injection needle to be blocked, effectively improving the qualified rate of injection needle production and improving product quality.

[0011] A further solution is that the wiping unit is installed on a movable base.

[0012] As can be seen from the above, by installing the wiping unit on the movable seat, it is beneficial to shorten the travel and time of the dispensing head relative to the wiping unit, optimize the action of the second driving mechanism, thereby improving the dispensing efficiency of the wiping unit and improving the efficiency of removing overflowed photosensitive glue.

[0013] A preferred solution is that a first positioning block, a second positioning block and a third positioning block are provided on the movable seat, and in the extension direction of the first positioning block, the first positioning block is located between the second positioning block and the third positioning block; the wiping unit also includes a mounting seat, the mounting seat is installed on the movable seat, the mounting seat is arranged opposite to the first positioning block, the mounting seat, the first positioning block, the second positioning block and the third positioning block form a fixed position, the clamp is installed in the fixed position, the mounting seat is provided with a receiving groove, and the wiping member is installed in the receiving groove.

[0014] As can be seen from the above, this design allows the fixture to be disassembled relative to the movable seat, thereby facilitating the preparation of the fixture, improving the safety of preparing the fixture, and improving the efficiency of preparing the fixture; in addition, through the coordination design between the movable seat, the fixture and the mounting seat, it is helpful to simplify the structure for disassembling and assembling the fixture.

[0015] A further solution is that a spring plunger is provided on the mounting seat, and a positioning bead of the spring plunger protrudes from a side of the mounting seat facing the first positioning block.

[0016] As can be seen from the above, adding a spring plunger to the mounting seat can make the disassembly and assembly of the fixture more convenient, and ensure the stability and reliability of the clamping of the fixture during the dispensing and curing process, thereby ensuring the dispensing processing quality of the dispensing unit.

[0017] Another preferred solution is that the number of dispensing heads is more than two, and the more than two dispensing heads are distributed along a first direction, and the first direction is perpendicular to the axial direction of the dispensing head and the moving direction of the movable seat; the number of accommodating positions is N times the number of dispensing heads, N ≥ 1, N is an integer, and the more than two accommodating positions are distributed along the first direction.

[0018] As can be seen from the above, this design is beneficial to reducing the number of times the fixture is prepared, so as to improve the processing efficiency of the injection needle automatic dispensing and curing equipment.

[0019] A further solution is that the automatic dispensing and curing device for injection needles also includes an anti-drip unit, which includes a third driving mechanism and a liquid collecting tray, and the third driving mechanism can drive the liquid collecting tray to move below the dispensing head.

[0020] As can be seen from the above, the anti-drip unit can prevent the photosensitive glue overflowing from the dispensing head during the preparation process of the fixture and the curing process of the injection needle from dripping onto the automatic dispensing and curing equipment of the injection needle, thereby avoiding contamination of the automatic dispensing and curing equipment of the injection needle and ensuring the reliability of the operation of related functional units (such as the material transfer unit); and the anti-drip unit can also prevent the photosensitive glue overflowing from the dispensing head after the fixture is moved to the dispensing position and before the dispensing unit performs the dispensing process on the injection needle from dripping onto the fixture and / or the injection needle, thereby preventing the fixture and the injection needle from being contaminated and ensuring the processing quality and pass rate of the injection needle.

[0021] A further solution is that the liquid collecting tray has a liquid storage tank, and a liquid absorbing member is arranged in the liquid storage tank.

[0022] As can be seen from the above, by arranging a liquid absorbing member in the liquid storage tank, it is possible to prevent the recovered photosensitive adhesive in the liquid collecting tray from spilling out of the liquid collecting tray due to inertia and shaking when the third driving mechanism drives the liquid collecting tray to move.

[0023] A further solution is that the wiping member is a sponge; and the liquid absorbing member is a sponge or a cloth.

[0024] As can be seen from the above, a sponge is used as a wiping piece, so that the wiping piece can effectively absorb and remove the photosensitive glue overflowing from the dispensing head, so that when the needle tube of the dispensing head is inserted into the wiping piece, the needle tube of the dispensing head will not be deformed, and the wiping piece can wipe and clean the needle tube of the dispensing head; and a sponge or cloth is used as a liquid absorbing piece, so that the liquid absorbing piece can reliably absorb the photosensitive glue recovered in the liquid collection tray to limit the movement of the photosensitive glue and prevent the photosensitive glue from spilling out of the liquid collection tray due to inertia and shaking.

[0025] A further solution is that a drainage hole is provided on the liquid collecting tray, and the drainage hole is communicated with the liquid storage tank.

[0026] As can be seen from the above, this design is conducive to more convenient and timely removal of the photosensitive adhesive recovered in the liquid collection tray, thereby preventing the photosensitive adhesive in the liquid collection tray from being overfilled and overflowing.

[0027] A further solution is that the number of material moving units, dispensing units, light-curing units, wiping units and anti-drip units are all more than two; when the movable seat is in the curing position, the wiping member is located outside the illumination range of the light-curing unit; the first driving mechanism is a first linear module, the second driving mechanism includes a second linear module and a third linear module, the second linear module can drive the third linear module to move in the height direction of the injection needle automatic dispensing and curing equipment, the third linear module drives the dispensing head to move in the first direction, and the moving direction, height direction and first direction of the movable seat are perpendicular to each other; the third driving mechanism is a linear cylinder, and the moving direction of the liquid collection tray is parallel to the moving direction of the movable seat.

[0028] It can be seen from the above that by designing the number of material moving units, dispensing units, light-curing units, wiping units and anti-drip units, the production efficiency of the automatic dispensing and curing equipment for injection needles can be better and more reasonably improved; and when curing the injection needle after the dispensing treatment, the wiper is positioned outside the illumination range of the light-curing unit to avoid curing of the photosensitive adhesive on the wiper, thereby ensuring the wiping effect of the wiper on the dispensing head and extending the service life of the wiper.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0036] Reference Figure 1 and Figure 2 The automatic dispensing and curing device 100 for injection needles includes a frame 1, a material moving unit 2, a dispensing unit 3, a light curing unit 4, a fixture 5, a wiping unit 6, an anti-drip unit 7, a glue preparation unit 8 and a control unit 9. The material moving unit 2, the dispensing unit 3, the light curing unit 4, the anti-drip unit 7, the glue preparation unit 8 and the control unit 9 are all installed on the frame 1, and the control unit 9 is electrically connected to the material moving unit 2, the dispensing unit 3, the light curing unit 4, the anti-drip unit 7 and the glue preparation unit 8, respectively, to coordinate the actions of each functional unit. Among them, the automatic dispensing and curing device 100 for injection needles has a dispensing position and a curing position, the dispensing unit 3 is arranged at the dispensing position, and the light curing unit 4 is arranged at the curing position.

[0037] Combination Figure 3 , the material moving unit 2 includes a first driving mechanism 21 and a moving seat 22. The first driving mechanism 21 is installed on the frame 1, and the clamp 5 is installed on the moving seat 22. The first driving mechanism 21 is used to drive the moving seat 22 to move between the glue dispensing position and the curing position, so that the clamp 5 moves between the glue dispensing position and the curing position. Preferably, the first driving mechanism 21 is a first linear module, and the glue dispensing position and the curing position are distributed along the direction in which the first linear module drives the moving seat 22 to move; by adopting the first linear module as the first driving mechanism 21, the material moving unit 2 can drive the clamp 5 and the injection needle 10 on the clamp 5 to move smoothly from the glue dispensing position to the curing position, so as to avoid the relative position of the needle seat and the needle tube of the injection needle 10 from being offset during the movement, and to prevent the uncured photosensitive glue on the injection needle 10 from spilling.

[0038] Combination Figure 4 The dispensing unit 3 includes a second driving mechanism 31, a connecting seat 32 and a dispensing head 33. The connecting seat 32 is connected to the driving end of the second driving mechanism 31, and the dispensing head 33 is installed on the connecting seat 32, so that the second driving mechanism 31 can drive the dispensing head 33 to move to the fixture 5 through the connecting seat 32 to perform dispensing on the injection needle 10 on the fixture 5. Among them, the dispensing head 33 is parallel to the height direction of the injection needle automatic dispensing curing device 100.

[0039] Preferably, the second driving mechanism 31 includes a second linear module 311 and a third linear module 312. The second linear module 311 is mounted on the frame 1, and the third linear module 312 is mounted on the driving end of the second linear module 311, and the second linear module 311 is used to drive the third linear module 312 to move in the height direction. The connecting seat 32 is mounted on the driving end of the third linear module 312, and the third linear module 312 is used to drive the connecting seat 32 to move along the first direction; wherein the first direction, the height direction and the moving direction of the moving seat 22 are perpendicular to each other. By adopting the combination mechanism of the second linear module 311 and the third linear module 312 as the second driving mechanism 31, the second driving mechanism 31 can accurately and smoothly drive the dispensing head 33 to move, so as to ensure that the dispensing head 33 can accurately perform dispensing processing on the connection between the needle seat of the injection needle 10 on the fixture 5 and each needle tube, thereby ensuring the accuracy and dispensing quality of the dispensing head 33.

[0040] Combination Figure 5 The clamp 5 has a receiving position 51, which is used to position and fix the injection needle 10 to be glued and cured, so as to ensure the position accuracy of the injection needle 10, so that the glue dispensing head 33 of the glue dispensing unit 3 can accurately perform glue dispensing on the connection between the needle seat of the injection needle 10 and each needle tube.

[0041] Preferably, the number of the dispensing heads 33 of the dispensing unit 3 is more than two, and the more than two dispensing heads 33 are distributed along the first direction; the number of the accommodating positions 51 on the fixture 5 is N times the number of the dispensing heads 33, wherein N ≥ 1, and N is an integer, and the more than two accommodating positions 51 are distributed along the first direction; this design is conducive to reducing the number of times the fixture 5 is prepared, so as to improve the processing efficiency of the automatic dispensing curing device 100 for injection needles. For example, in this embodiment, the dispensing unit 3 includes three dispensing heads 33; the number of the accommodating positions 51 on the fixture 5 is twice the number of the dispensing heads 33 of the dispensing unit 3, that is, the fixture 5 has six accommodating positions 51.

[0042] See also Figure 3 The wiping unit 6 preferably includes a wiping member 61 and a mounting group 62. The second driving mechanism 31 of the dispensing unit 3 can also drive the dispensing head 33 to move to the wiping unit 6, so that the wiping unit 6 can clean the photosensitive glue overflowing from the needle tube 331 of the dispensing head 33.

[0043] It can be seen that before each round of dispensing operation of the dispensing unit 3, the second driving mechanism 31 drives the dispensing head 33 to move to the wiping member 61, so that the wiping member 61 adsorbs the photosensitive glue overflowing on the dispensing head 33, and can also wipe and clean the syringe 331 of the dispensing head 33, thereby preventing the overflowing photosensitive glue from dripping onto the processed injection needle 10, avoiding the contamination of the injection needle 10 by the photosensitive glue and / or avoiding the blockage of the syringe of the injection needle 10, effectively improving the qualified rate of the production of the injection needle 10 and enhancing the product quality. Among them, a receiving groove 621 is provided on the mounting group 62, and the wiping member 61 is mounted in the receiving groove 621.

[0044] The wiping member 61 is preferably made of sponge, so that the wiping member 61 can effectively adsorb and remove the photosensitive glue overflowing on the dispensing head 33, and when the syringe 331 of the dispensing head 33 is inserted into the wiping member 61, the syringe 331 of the dispensing head 33 will not be deformed, and the wiping member 61 can wipe and clean the syringe 331 of the dispensing head 33. Preferably, the mounting group 62 is mounted on the moving seat 22, which is beneficial to shortening the stroke and time of the relative movement of the dispensing head 33 with respect to the wiping unit 6, optimizing the movement of the second driving mechanism 31, and effectively improving the dispensing efficiency of the wiping unit 6 and the cleaning efficiency of the overflowing photosensitive glue.

[0045] Furthermore, a first positioning block 221, a second positioning block 222 and a third positioning block 223 are provided on the moving seat 22. The first positioning block 221 extends along the first direction, and in the extending direction of the first positioning block 221 (i.e., the first direction), the first positioning block 221 is located between the second positioning block 222 and the third positioning block 223, so that the first positioning block 221, the second positioning block 222 and the third positioning block 223 enclose a shape similar to "凵", and further enable the first positioning block 221, the second positioning block 222 and the third positioning block 223 to perform three-sided positioning on the fixture 5. The mounting group 62 is arranged opposite to the first positioning block 221, so that a fixing position 220 is formed between the mounting group 62, the first positioning block 221, the second positioning block 222 and the third positioning block 223, and the fixture 5 is detachably mounted in the fixing position 220. The design enables the fixture 5 to be detached relative to the moving seat 22, which is convenient for preparing materials for the fixture 5, improving the safety of preparing materials for the fixture 5, and improving the efficiency of preparing materials for the fixture 5; in addition, through the cooperative design among the moving seat 22, the fixture 5 and the mounting group 62, it is beneficial to simplify the structure of disassembling and assembling the fixture 5. Among them, when the moving seat 22 is in the curing position, the wiping member 61 is preferably located outside the illumination range of the light curing unit 4 to avoid the photosensitive glue on the wiping member 61 from being cured, thereby ensuring the wiping effect of the wiping member 61 on the dispensing head 33 and prolonging the service life of the wiping member 61.

[0046] Furthermore, a spring plunger 63 is provided on the installation group 62, wherein the positioning column of the spring plunger 63 protrudes from the side of the installation group 62 facing the first positioning block 221. The addition of the spring plunger 63 on the installation group 62 can make the disassembly and assembly of the clamp 5 more convenient, and ensure the stability and reliability of the clamping of the clamp 5 during the dispensing and curing process, thereby ensuring the dispensing processing quality of the dispensing unit 3.

[0047] Combination Figure 6 The anti-drip unit 7 includes a third driving mechanism 71 and a liquid collecting tray 72. The third driving mechanism 71 is installed on the frame 1, and is used to drive the liquid collecting tray 72 to move to the bottom of the dispensing head 33; the liquid collecting tray 72 has a liquid storage tank 721, and the liquid storage tank 721 is used to recover the photosensitive glue dripping from the needle tube 331 of the dispensing head 33, wherein the moving direction of the liquid collecting tray 72 is preferably parallel to the moving direction of the moving seat 22. The anti-drip unit 7 can prevent the photosensitive glue overflowing from the dispensing head 33 during the preparation process of the clamp 5 and the curing process of the injection needle 10 from dripping onto the automatic dispensing and curing equipment 100 for the injection needle, thereby avoiding contamination of the automatic dispensing and curing equipment 100 for the injection needle and ensuring the reliability of the operation of related functional units (such as the material moving unit 2); in addition, the anti-drip unit 7 can also prevent the photosensitive glue overflowing from the dispensing head 33 after the clamp 5 is moved to the dispensing position and before the dispensing unit 3 performs the dispensing process on the injection needle 10 from dripping onto the clamp 5 and / or the injection needle 10, thereby preventing the clamp 5 and the injection needle 10 from being contaminated and ensuring the processing quality and pass rate of the injection needle 10.

[0048] Preferably, a liquid absorbing member 722 is provided in the liquid storage tank 721. By providing the liquid absorbing member 722 in the liquid storage tank 721, it is possible to prevent the recovered photosensitive adhesive in the liquid collection tray 72 from spilling out of the liquid collection tray 72 due to inertia and shaking during the process of the third driving mechanism 71 driving the liquid collection tray 72 to move. The liquid absorbing member 722 is preferably a sponge, so that the liquid absorbing member 722 can reliably absorb the recovered photosensitive adhesive in the liquid collection tray 72 to limit the movement of the photosensitive adhesive and prevent the photosensitive adhesive from spilling out of the liquid collection tray 72 due to inertia and shaking. Of course, as another optional solution, the liquid absorbing member 722 can also be a cloth.

[0049] In addition, a drainage hole 723 is provided on the liquid collecting tray 72, and the drainage hole 723 is connected to the liquid storage tank 721, and a sealing plug is provided in the drainage hole 723. When the photosensitive adhesive recovered in the liquid storage tank 721 is relatively full, the photosensitive adhesive recovered in the liquid storage tank 721 can be removed by pulling out the sealing plug, thereby avoiding the photosensitive adhesive in the liquid storage tank 721 from being overfilled and overflowing. It can be seen that the provision of the drainage hole 723 is conducive to more convenient and timely removal of the photosensitive adhesive recovered in the liquid collecting tray 72. Furthermore, the third driving mechanism 71 is preferably a linear cylinder, so that the third driving mechanism 71 can quickly drive the liquid collecting tray 72 to move relative to the dispensing head 33, thereby reasonably improving the processing efficiency of the injection needle automatic dispensing curing device 100.

[0050] See also Figure 1 The glue preparation unit 8 includes glue preparation tubes 81, the number of which is equal to the number of glue dispensing heads 33, and one glue preparation tube 81 is matched and connected with one glue dispensing head 33. For example, in the present embodiment, the number of glue preparation tubes 81 is three; the glue preparation tubes 81 are used to supply photosensitive glue to the glue dispensing heads 33.

[0051] In addition, the number of material moving units 2, glue dispensing units 3, photocuring units 4, wiping units 6, anti-drip units 7, and glue preparation units 8 are preferably more than two; more than two glue dispensing units 3 correspond to more than two material moving units 2 one-to-one, more than two photocuring units 4 correspond to more than two material moving units 2 one-to-one, more than two wiping units 6 correspond to more than two material moving units 2 one-to-one, and more than two anti-drip units 7 correspond to more than two material moving units 2 one-to-one; more than two glue preparation units 8 correspond to more than two glue dispensing units 3 one-to-one. By designing the number of material moving units 2, glue dispensing units 3, photocuring units 4, wiping units 6, anti-drip units 7, and glue preparation units 8, the production efficiency of the automatic glue dispensing and curing equipment 100 for injection needles can be better and more reasonably improved. For example, in the present embodiment, the number of material moving units 2, glue dispensing units 3, photocuring units 4, wiping units 6, and anti-drip units 7 is preferably two.

[0052] The working process of the automatic dispensing and curing device 100 for injection needles is briefly described below:

[0053] In the initial state, the third driving mechanism 71 of the anti-drip unit 7 drives the liquid collecting tray 72 to extend so that the liquid collecting tray 72 is located below the dispensing head 33 of the dispensing unit 3, thereby preventing the photosensitive glue overflowing from the needle tube 331 of the dispensing head 33 from dripping onto at least one of the frame 1, the material transfer unit 2, the clamp 5, the wiping unit 6 and the injection needle 10 to be processed.

[0054] Next, the prepared fixture 5 is placed on the movable seat 22 of the material transfer unit 2; then, the first driving mechanism 21 of the material transfer unit 2 drives the movable seat 22 to move to the dispensing position, and the wiping member 61 of the wiping unit 6 on the movable seat 22 is positioned directly below the dispensing head 33.

[0055] Next, the third driving mechanism 71 of the anti-drip unit 7 drives the liquid collection tray 72 to retract; then, the second driving mechanism 31 of the dispensing unit 3 drives the dispensing head 33 to move downward and insert it into the wiping member 61 to absorb and remove the photosensitive glue overflowing from the needle tube 331 of the dispensing head 33; then, the second driving mechanism 31 drives the dispensing head 33 to move upward and reset.

[0056] Next, the second driving mechanism 31 of the dispensing unit 3 drives the dispensing head 33 to perform dispensing on the needle seat and each needle tube of the injection needle 10 it is responsible for one by one according to the preset dispensing sequence; at the same time, the first driving mechanism 21 of the material transfer unit 2 drives the movable seat 22 to move according to the preset dispensing sequence, so as to cooperate with the dispensing unit 3 to perform dispensing on the needle seat and needle tube of each injection needle 10.

[0057] When the dispensing unit 3 completes the dispensing process on each injection needle 10, the second driving mechanism 31 of the dispensing unit 3 drives the dispensing head 33 to move up and reset; then, the third driving mechanism 71 of the anti-drip unit 7 drives the liquid collecting tray 72 to extend again so that the liquid collecting tray 72 is located below the dispensing head 33 of the dispensing unit 3.

[0058] Next, the first driving mechanism 21 of the material moving unit 2 drives the moving seat 22 to move to the curing position, and the light curing unit 4 cures the photosensitive adhesive on the injection needle 10 that has completed the glue dispensing process.

[0059] After the curing process of the photosensitive glue on the injection needles 10 is completed, the first driving mechanism 21 of the material moving unit 2 drives the movable seat 22 to retreat to the initial position, so that the staff or the material taking and unloading equipment can take out the clamp 5 on the movable seat 22 and put it back into another prepared clamp 5, and then repeat the above steps to perform glue dispensing and curing process on the next batch of injection needles 10.

[0060] In summary, it can be seen that through the design of the automatic dispensing and curing equipment 100 for injection needles, it is possible to realize the automated dispensing and curing processing of the injection needles 10, so as to improve the qualified rate and processing efficiency of the dispensing and curing of the injection needles 10, reduce the production cost, and also meet the requirements of mass production; in addition, the automatic dispensing and curing equipment 100 for injection needles can also remove the photosensitive glue overflowing from the needle tube 331 of the dispensing head 33 to ensure the qualified rate of the injection needles 10; furthermore, the automatic dispensing and curing equipment 100 for injection needles can also prevent the photosensitive glue overflowing from the needle tube 331 of the dispensing head 33 from dripping onto at least one of the frame 1, the material transfer unit 2, the clamp 5, the wiping unit 6 and the injection needle 10 to be processed, so as to prevent the working environment from being polluted, and to protect the functional units such as the material transfer unit 2, and to ensure the reliability of the working of the functional units such as the material transfer unit 2.
