Description

Technical Field

[0001] This application relates to the field of blade assembly equipment, and in particular to an automatic cutting blade assembly device. Background Technology

[0002] Equipment assembly is the process of combining various parts, components, or parts to form a complete device or system. This process plays a crucial role in modern technological development and industrial production.

[0003] Reference Figure 1 A lawnmower blade includes two staggered, elongated blades. Each blade has multiple elongated holes extending along its length, and locking components for securing the two blades are disposed within these holes. The locking components include nuts, bolts, and washers. In the prior art, blade assembly typically involves manually installing the locking components one by one, which is inefficient and increases the workload for assembly personnel. Summary of the Invention

[0004] To improve the assembly efficiency of cutting blades, this application provides an automatic cutting blade assembly device.

[0005] The automatic assembly equipment for cutting blades provided in this application adopts the following technical solution:

[0006] An automatic cutting blade assembly device includes an assembly platform, on which are provided a placement table for placing the blade, a tightening mechanism for tightening bolts, a first drive mechanism for driving the tightening mechanism to slide along the length direction of the blade and to move vertically, a first feeding mechanism for feeding nuts, a second feeding mechanism for feeding washers, a third feeding mechanism for feeding bolts, and a second drive mechanism for driving the placement table to slide along the width direction of the blade.

[0007] By adopting the above technical solution, when using the above-mentioned blade assembly equipment, multiple nuts are positioned and installed on the placement table by the first feeding mechanism. Then, the assembly personnel position the blade on the placement table, with the slotted holes of the blade corresponding one-to-one with the nuts. The second and third feeding mechanisms sequentially position and install the gaskets and bolts on the blade. Then, the second drive mechanism moves the placement table to the side of the tightening mechanism. The first drive mechanism drives the horizontal movement and vertical lifting of the tightening mechanism, so that the pre-fixed bolt groups on the blade are tightened sequentially, realizing the automatic assembly of the blade. The above assembly method realizes the automatic feeding and automatic tightening of the bolt groups, improving the assembly efficiency of the blade.

[0008] Optionally, the placement platform is provided with a plurality of nut seats for placing nuts at intervals, and the placement platform has a sliding groove for the nut seats to slide. The nut seat includes a sliding part that cooperates with the sliding groove, an abutting part that abuts against the top of the placement platform, and a positioning part located at the top of the abutting part and arranged along the length direction of the blade. The nut seat has a positioning countersunk hole in the positioning part for positioning the nut, and the nut has a fixing member in the abutting part for fixedly connecting with the placement platform.

[0009] By adopting the above technical solution, the positioning countersunk hole on the nut seat can be used to position the nut and ensure its stability. Through the cooperation of the sliding part and the sliding groove, the nut can be slidably installed, so that the placement table can be adapted to the installation of blades of different sizes. The nut seat is fixed by the fastener, and the fixing method is simple and convenient.

[0010] Optionally, it also includes a channel steel that is inserted into and mates with a plurality of the nut seats. The channel steel has an insertion groove adapted to the positioning part and a slot that corresponds one-to-one with the positioning countersunk hole. The top of one of the nut seats is also provided with a clamping seat for clamping the two side walls of the channel steel, and the clamping seat is adjustable by sliding along the width direction of the blade.

[0011] By adopting the above technical solution, when positioning and placing the blade, the channel steel is first placed on multiple nut seats, and then the blade is placed on top of the channel steel. The arrangement of the channel steel can increase the contact area between the blade and the placement table, making the blade more stable. The arrangement of the clamping seat can improve the connection strength of the channel steel.

[0012] Optionally, the tightening mechanism includes a tightening bracket fixed to the first driving mechanism, a tightening drive component disposed on the tightening bracket, a tightening bit connected to the tightening drive component, and a tightening guide assembly that is lifted and lowered on the tightening bracket and used to guide the tightening bit. The bottom of the tightening bracket is provided with a clamping assembly for pressing against the blade. The clamping assembly includes a clamping fixing plate, a clamping telescopic component disposed at the bottom of the clamping fixing plate, and a clamping abutment plate fixed to the end of the clamping telescopic component.

[0013] By adopting the above technical solution, the setting of the tightening mechanism is disclosed. After the bolt assembly is positioned on the blade, the first driving mechanism causes the clamping component to abut against the top of the blade, improving the stability during the tightening operation. Then, the tightening guide component is activated, causing the tightening bit to move downward and abut against the top of the bolt. Then, the tightening drive component is activated to tighten the bolt and nut, completing the assembly of a set of bolts. The tightening mechanism is reset, and the above tightening operation is repeated to complete the assembly of the blade.

[0014] Optionally, the tightening guide assembly includes a tightening lifting cylinder disposed on the tightening bracket, a tightening lifting plate connected to the tightening lifting cylinder, and a tightening lifting slide rail that slides and cooperates with the tightening lifting plate. The tightening lifting plate is fixedly sleeved on the tightening bit, and a buffer elastic element is provided at the end of the output shaft of the tightening lifting cylinder.

[0015] By adopting the above technical solution, the disclosed tightening guide assembly can guide the lifting and lowering of the tightening bit, improve the stability of tightening the bit, and at the same time, the buffer elastic element can buffer the downward rotation of the tightening bit.

[0016] Optionally, the first driving mechanism includes a first fixed bracket, a first frame that is slidably disposed on the first fixed bracket, and a first horizontal driving member that drives the first frame to move horizontally along the first fixed bracket. The first frame is provided with a first lifting driving member that drives the tightening bracket to move vertically up and down.

[0017] By adopting the above technical solution, the composition of the first drive mechanism is disclosed. The first drive mechanism can realize the sliding of the tightening mechanism along the blade length direction and the vertical lifting and lowering in the height direction on the placement table, and perform tightening operation on multiple bolt assemblies on the blade. The above drive mechanism has a simple structure and is easy to assemble.

[0018] Optionally, the second drive mechanism includes a second frame for fixed installation on the placement platform, a second slider disposed at the bottom of the second frame, a second slide rail fixed to the assembly platform and cooperating with the second slider, and a second horizontal drive component for driving the second frame to move horizontally. Two sets of the second drive mechanisms are disposed on the assembly platform, and the two sets of the second drive mechanisms are staggered along the height direction.

[0019] By adopting the above technical solution, the composition of the second drive mechanism is disclosed. The second drive mechanism enables the placement table to slide along the width direction of the blade. The arrangement of two sets of second drive mechanisms allows the other set of placement tables to perform the loading operation of blades and bolts while one set of blades is being tightened, thereby improving the assembly efficiency of the blades.

[0020] Optionally, the first feeding mechanism includes a first feeding frame disposed at one end of the assembly platform away from the first driving mechanism, a first feeding component disposed on the first feeding frame, and a first detection component for detecting the positioning countersunk hole. The first feeding frame is provided with a first horizontal module that drives the first feeding mechanism to slide along the blade length direction. The first feeding component includes a first feeding fixing plate, a first feeding lifting plate that is lifted and lowered on the first feeding fixing plate, a nut feeding tube storing nuts, and a nut clamping component that pushes the nuts to the positioning countersunk hole.

[0021] By adopting the above technical solution, the first feeding mechanism can automatically feed the nuts onto the nut seat. After the first feeding fixing plate moves horizontally above the nut seat, the nut is pushed into the positioning countersunk hole by the nut clamping component. Compared with the need to manually place the nuts one by one, the assembly efficiency of the blade is improved.

[0022] Optionally, the second feeding mechanism includes a second feeding frame disposed between the first feeding mechanism and the first driving mechanism, a second feeding assembly disposed on the second feeding frame, a second horizontal module for driving the second feeding assembly to slide along the blade length direction, and a gasket feeding plate; the second feeding assembly includes a second feeding fixing plate, a second feeding lifting plate that is lifted and lowered on the second feeding fixing plate, and a clamping member disposed on the second feeding lifting plate for clamping the gasket, the clamping member being connected to the second feeding lifting plate via a cylinder; there is a placement gap between the channel steel and the second feeding lifting plate for arranging a single gasket, the gasket feeding plate and the blade are engaged, and the top surface is provided with a gasket slot for horizontally inserting the gasket and a release slot communicating with the gasket slot.

[0023] By adopting the above technical solution, the second feeding mechanism can automatically feed the gaskets to the top of the blade. Compared with the need for manual placement of the gaskets one by one, the above mechanism improves the assembly efficiency of the blade.

[0024] Optionally, the third feeding mechanism includes a third feeding frame disposed between the second feeding mechanism and the first driving mechanism, a third feeding assembly disposed on the third feeding frame, and a second detection element for detecting the gasket. The third feeding frame is provided with a third horizontal module that drives the third feeding mechanism to slide along the blade length direction. The third feeding assembly includes a third feeding fixing plate, a third feeding lifting plate that is lifted and lowered on the third feeding fixing plate, a bolt feeding tube storing bolts, and a bolt clamping element for inserting bolts into the gasket.

[0025] By adopting the above technical solution, the second feeding mechanism can automatically feed the bolts to the top of the blade. Compared with the need for manual placement of the gaskets one by one, the above mechanism improves the assembly efficiency of the blade.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0042] The following is in conjunction with the appendix Figure 2-11 This application will be described in further detail.

[0043] This application discloses an automatic assembly device for cutting blades.

[0044] Reference Figure 1An automatic cutting blade assembly device includes an assembly platform 1, on which are arranged a placement table 2 for positioning and placing the blade, a tightening mechanism 3 for tightening bolts, a first drive mechanism 4 for driving the tightening mechanism 3 to move horizontally or vertically, a second drive mechanism 5 for driving the placement table 2 to slide horizontally along the width direction of the blade, a first feeding mechanism 6 for feeding nuts, a second feeding mechanism 7 for feeding washers, and a third feeding mechanism 8 for feeding bolts. In this application, the length direction of the blade is defined as the X direction, the width direction of the blade as the Y direction, and the height direction as the Z direction.

[0045] During blade assembly, the first feeding mechanism 6 first positions and installs the nut on the placement platform 2, then the blade is installed on the top of the placement platform 2, and the second feeding mechanism 7 and the third feeding mechanism 8 sequentially install the gasket and bolt on the top of the blade, and the bolt and nut are initially positioned; then the second drive mechanism 5 moves the placement platform 2 and the blade synchronously to the side of the tightening mechanism 3; the first drive mechanism 4 drives the tightening mechanism 3 to move horizontally or rise vertically, and the tightening mechanism 3 locks and fixes multiple sets of bolts and nuts.

[0046] Reference Figure 1 and Figure 2 The first drive mechanism 4 includes a first fixed bracket 41, a first frame 42 slidably disposed on the first fixed bracket 41, a first horizontal drive member 43 driving the first frame 42 to move horizontally, and a first lifting drive member 44 disposed on the first frame 42 and driving the tightening mechanism 3 to move up and down. Both the first horizontal drive member 43 and the first lifting drive member 44 are driven by motors.

[0047] The first fixed bracket 41 is a U-shaped bracket arranged along the X direction. A first horizontal slide rail 411 is provided on one side of the first fixed bracket 41, which slides and engages with the first frame 42. A first horizontal drive member 43 is horizontally fixed to one end of the first fixed bracket 41, and its output shaft is connected to a horizontally arranged screw. The other end of the screw is rotatably engaged with the fixed bracket. The first fixed bracket 41 has a drive block that threadedly engages with the first screw. When the first drive member is activated and drives the screw to rotate, the first frame 42 can move horizontally back and forth along the X direction under the action of the drive block.

[0048] The first frame 42 has a vertically arranged first vertical slide rail 421 that slides and engages with the tightening mechanism 3. The first lifting drive 44 is fixedly installed on the top of the first frame 42, and its output shaft is connected to a vertically arranged screw. The lifting principle of the tightening mechanism 3 is consistent with the horizontal movement principle of the first frame 42, both of which are achieved through the cooperation of a motor, screw, and slider.

[0049] The tightening mechanism 3 includes a tightening bracket 31, a tightening drive 32 disposed on the top of the tightening bracket 31, a tightening bit 33 connected to the tightening drive 32, a tightening guide assembly 34 which is lifted and lowered on the tightening bracket 31 and used to guide the tightening bit 33, and a pressing assembly 35 disposed at the bottom of the tightening bracket 31.

[0050] Reference Figure 3 and Figure 4 The tightening bracket 31 is generally L-shaped, with its longer side slidingly connected to the first vertical slide rail 421, and its shorter side used for the fixed installation of the tightening drive component 32. The tightening bit 33 is an electric telescopic bit in the prior art, with a bit end adapted to the end of the bolt. The clamping assembly 35 includes a clamping fixing plate 351 fixed to the bottom of the tightening bracket 31, a clamping telescopic component 352 disposed at the bottom of the clamping fixing plate 351, and a clamping abutment plate 353 connected to the end of the clamping telescopic component.

[0051] Both the clamping fixing plate 351 and the clamping abutment plate 353 have clamping through holes 354 penetrating their upper and lower end faces. The clamping through holes 354 and the tightening bit 33 are arranged coaxially. Before the tightening mechanism 3 is activated, the tightening bit 33 is located between the clamping fixing plate 351 and the clamping abutment plate 353, so that when the bolt is tightened, the clamping abutment plate 353 first presses against the top surface of the blade, ensuring the stability of the blade. The clamping assembly 35 has two sets of clamping telescopic members 352, which are respectively arranged on opposite sides of the clamping through holes 354. The clamping telescopic member 352 includes a clamping telescopic post 3521 whose two ends are respectively connected to the clamping fixing plate 351 and the clamping abutment plate 353, and a clamping spring 3522 sleeved on the clamping telescopic post 3521.

[0052] The tightening guide assembly 34 includes a tightening lifting cylinder 341 fixed to one side of the tightening bracket 31, a tightening lifting plate 342 connected to the tightening lifting cylinder 341, a tightening lifting slide rail 344 that slides with the tightening lifting plate 342, and a buffer elastic element 345 disposed at the end of the output shaft of the tightening lifting cylinder 341. The cylinder body of the tightening lifting cylinder 341 is fixed to the tightening bracket 31 by a tightening connecting plate. The tightening lifting plate 342 has a sleeve fixedly fitted with a tightening bit 33 to improve the stability of the tightening bit 33 during extension and retraction. The tightening lifting slide rail 344 is vertically fixed to the tightening bracket 31 by bolts. The tightening lifting plate 342 has a guide connecting plate 3421 through which the output shaft of the tightening lifting cylinder 341 passes. The tightening lifting cylinder 341 has a tightening limiting part 343 at the end of its output shaft that abuts against the bottom of the guide connecting plate 3421. A sleeve is fixed to the output shaft of the tightening lifting cylinder 341. The buffer elastic element 345 is a spring element, with its two ends abutting against the top of the guide connecting plate 3421 and the bottom of the sleeve, respectively.

[0053] After the clamping abutment plate 353 presses against the top surface of the blade, the tightening lifting cylinder 341 is activated, causing the guide connecting plate 3421, the tightening lifting plate 342, and the tightening bit 33 to move down synchronously, so that the tightening bit 33 abuts against the bolt. At this time, the buffer elastic element 345 is in a compressed state. The tightening drive 32 is activated to rotate the tightening bit 33. During the tightening process, the tightening lifting plate 342 moves down a certain distance, and the buffer elastic element 345 also synchronously restores the same deformation.

[0054] Reference Figure 3 The second drive mechanism 5 includes a second frame 51 for fixing the placement platform 2, second sliders 52 disposed on both sides of the bottom of the second frame 51, a second slide rail 53 disposed on the assembly platform 1, and a second horizontal drive member 54 for driving the second frame 51 to move. The second frame 51 is a rectangular plate extending along the X direction, and the second sliders 52 are fixed to both sides of the bottom of the second frame 51 by bolts. The second slide rail 53 extends along the Y direction and slides in cooperation with the second sliders 52. The second horizontal drive member 54 is driven by a motor screw, and its output shaft is fixedly connected to the second frame 51. In this embodiment, the top of the assembly platform 1 has two sets of second drive mechanisms 5, which are staggered along the height direction.

[0055] Reference Figure 5 The top of the placement platform 2 is provided with multiple nut seats 21 for placing nuts at intervals along the X direction. The nut seats 21 are slidably installed on the placement platform 2, and the top of the placement platform 2 is provided with T-shaped sliding grooves 22 that penetrate both end faces along the X direction.

[0056] The nut seat 21 includes a sliding portion 211 that mates with the sliding groove 22, an abutting portion 212 that abuts against the top surface of the placement platform 2, and a positioning portion 213 located on top of the abutting portion 212 and extending along the X direction. A positioning countersunk hole 2131 for positioning the nut is provided in the center of the positioning portion 213. The nut seat 21 has a fixing member 2121 on the abutting portion 212 for fixing to the placement platform 2. In this embodiment, the fixing member 2121 is a bolt.

[0057] To improve the stability of the blade placement, this application also includes a strip-shaped channel steel 23 that engages with multiple nut seats 21. The channel steel 23 has a slot that engages with the positioning part and a slot corresponding to the positioning countersunk hole. A clamping seat 24 for holding and fixing the channel steel 23 is also provided at the top of the abutment portion 212 of one nut seat 21. The clamping seat 24 is fixed to the abutment portion 212 by bolts and can be adjusted along the Y direction to accommodate channel steel 23s of different widths. The arrangement of the channel steel 23 increases the contact area between the blade and the placement table 2, improving the stability of the tightening operation.

[0058] Reference Figure 6The first feeding mechanism 6 includes a first feeding rack 61 disposed at the end of the assembly platform 1 away from the first drive mechanism 4, a first feeding assembly 62 disposed on the first feeding rack 61, a first detection element 63 for detecting the positioning countersunk hole 2131, and a first horizontal module 64 for driving the first feeding assembly 62 to slide horizontally. The first feeding rack 61 extends along the X direction, and the principle of the first horizontal module 64 is the same as that of the first horizontal drive element 43. The first feeding assembly 62 includes a first feeding fixing plate 621, a first feeding lifting plate 622 that is lifted and lowered on the first feeding fixing plate 621, a nut feeding tube 623 storing nuts, and a nut clamping element 624 that pushes the nuts vertically into the positioning countersunk hole 2131.

[0059] The lifting mechanism of the first feeding lifting plate 622 is the same as that of the tightening bracket 31. The first detection element 63 consists of two infrared ranging devices that are tilted in opposite directions and fixed to the bottom of the first feeding lifting plate 622. The intersection of the light emitted by the two detection elements is coaxial with the nut arranged inside the first feeding lifting plate 622. When the first feeding mechanism 6 moves horizontally to the positioning countersunk hole 2131, the detection light emitted by the two first detection elements 63 intersects, and the control nut clamping element 624 is activated to press the nut into the corresponding positioning countersunk hole 2131.

[0060] Reference Figure 6 and Figure 7 A first feeding block is fixedly mounted on the first feeding lifting plate 622. The first feeding block has a vertically arranged nut feeding channel 6221 that extends through both end faces. A nut feeding pipe 623 is obliquely installed on the first feeding lifting plate 622 and communicates with the nut feeding channel 6221. In this embodiment, the nuts in the nut feeding pipe 623 are transported to the nut feeding channel 6221 by pneumatic drive. This feeding method is an existing method and is therefore not shown in the figure.

[0061] To prevent nuts from falling out of the nut feeding channel 6221, a limiting component 625 is provided on the bottom side wall of the first feeding lifting plate 622. The limiting component 625 includes two symmetrically arranged limiting blocks 6251 and limiting springs 6252 connecting the limiting blocks 6251. The first feeding lifting plate 622 has a limiting groove 6222 for arranging the limiting blocks 6251. The two ends of the limiting spring 6252 are respectively connected to the bottom wall of the limiting groove 6222 and the side wall of the limiting block 6251. In the normal state of the limiting spring 6252, the limiting block 6251 protrudes from the limiting groove 6222, and the top of the limiting block 6251 has an inclined surface. The nut clamping component 624 includes a vertically arranged nut clamping cylinder and a clamping support for fixing the nut clamping cylinder.

[0062] Among them, the bottom vertical cross section of the first feeding lifting plate 622 is convex, the nut feeding channel 6221 is located in the middle of the side with lower height, and the two detection pieces are located on the side with higher height respectively.

[0063] Reference Figure 8 The second feeding mechanism 7 is integrally disposed between the first feeding mechanism 6 and the first driving mechanism 4. It includes a second feeding frame 71, a second feeding assembly 72 disposed on the second feeding frame 71, a second horizontal module 73 that drives the second feeding assembly 72 to slide along the X direction, and a pad feeding plate 74. The second feeding assembly 72 includes a second feeding fixing plate 721, a second feeding lifting plate 722 that is lifted and lowered on the second feeding fixing plate 721, and a clamping member 723. The movement principle of the second feeding assembly 72 on the second feeding frame 71 is the same as that of the first feeding assembly 62.

[0064] Reference Figure 8 and Figure 9 The gasket feed plate 74 is an elongated strip plate used to position gaskets on top of the blade. Its end has a limiting retaining edge 741 that abuts against the end sidewall of the blade. The top surface of the gasket feed plate 74 has gasket grooves 742 spaced apart for horizontal insertion of gaskets. The gasket grooves 742 have an L-shaped cross-section, with one section gradually increasing in depth along the feeding direction of the second feeding mechanism 7 until the depth of the gasket groove 742 is the same as the depth of a single gasket. The gasket grooves 742 have through holes corresponding to the positioning countersunk holes 2131 for bolt insertion. These through holes penetrate the sidewall of the gasket feed plate 74 in the Y direction, allowing the gasket feed plate 74 to be pulled out from the top of the blade in the Y direction after the bolt is inserted into the gasket.

[0065] Combination Figure 10 A second feeding block is fixedly mounted on the second feeding lifting plate 722. The second feeding block has a semi-circular gasket placement groove 7221 on the side facing the feeding direction for placing stacked gaskets. The clamping member 723 includes a clamping plate 7231, a support plate 7233 located at the bottom of the clamping plate 7231, and a clamping cylinder 7232 fixed to the second feeding lifting plate 722. The clamping plate 7231 has an arc-shaped through groove symmetrical to the gasket placement groove 7221. The combination of the arc-shaped through groove and the gasket placement groove 7221 is adapted to the outer diameter of the gasket. The bottom of the second feeding lifting plate 722 also has a push ring 7222 for abutting against the gasket feeding plate 74 and pushing the gasket to move. The height of the push ring 7222 is the same as the height of a single gasket.

[0066] Reference Figure 11The third feeding mechanism 8 is located between the second feeding mechanism 7 and the first driving mechanism 4. It includes a third feeding frame 81, a third feeding component 82 disposed on the third feeding frame 81, a second detection component 83 for detecting the through hole of the gasket, and a third horizontal module 84 for driving the third feeding component 82 to move horizontally.

[0067] The third feeding rack 81 extends along the X direction, and the principle of the third horizontal module 84 is the same as that of the first horizontal module 64. The third feeding assembly 82 includes a third feeding fixing plate 821, a third feeding lifting plate 822 that is lifted and installed on the third feeding fixing plate 821, a bolt feeding pipe 823, and a bolt clamping member 824 that vertically inserts the bolt into the washer.

[0068] The lifting mechanism of the third feeding lifting plate 822 is the same as that of the first feeding lifting plate 622. The second detection component 83 operates on the same principle as the first detection component 63, and the intersection of the light rays emitted by the two detection components is coaxial with the bolt arranged in the third feeding lifting plate 822. When the third feeding mechanism 8 moves horizontally above the shim, the bolt clamping component 824 is activated to press the bolt into the corresponding shim.

[0069] The third feeding lifting plate 822 has a vertically arranged bolt feeding channel 8221 that runs through both end faces. The bolt feeding pipe 823 is installed obliquely on the third feeding lifting plate 822, and the bolt feeding method is the same as the nut feeding method.

[0070] The third feeding lifting plate 822 is also equipped with a limit component 625 on the bottom side wall of the bolt feeding channel 8221.

[0071] The implementation principle of an automatic cutting blade assembly device according to an embodiment of this application is as follows: First, the nuts are loaded and installed into multiple nut seats 21 by the first feeding mechanism 6. Then, the placement plate is moved along the Y direction to the second feeding mechanism 7 by the second driving mechanism 5. The assembly personnel sequentially install the channel steel 23, the blade and the gasket feeding plate 74 on the placement plate, and the gasket is pre-installed in the gasket slot 742 by the second feeding mechanism 7. Then, the placement table 2 is moved to the third feeding mechanism 8 by the second driving mechanism 5, and the bolts are inserted into the gaskets by the third feeding mechanism 8. Finally, the placement table 2 is moved to the tightening mechanism 3, and the assembly personnel pull out the gasket feeding plate 74 and tighten the multiple bolts by the tightening mechanism 3.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
