Abstract
Description
Technical Field
[0001] This invention relates to the field of stapler assembly technology, specifically to an automatic assembly device for the staple cartridge of an intracavitary cutting stapler. Background Technology
[0002] Currently, the assembly of pusher plates in the staple cartridge of the intracavitary cutting stapler is mostly completed by automated single machines. Existing assembly equipment is generally equipped with a linear vibration feeding mechanism and a multi-axis mechanical gripper. The mechanical gripper picks up the pusher plates one by one, transports them to the top of the staple cartridge, and then releases them. Then, the pressure head is used to press each pusher plate into the slot.
[0003] A search revealed a patent with publication number CN222243452U that discloses a pusher plate installation device for staplers. This patent uses negative pressure adsorption to replace the existing technology of positioning individual pusher plates by electrically controlled grippers, which improves the stability of the pusher plate gripping to a certain extent. However, it is essentially the same as the existing technology, which is still a single workpiece serial assembly. Only one pusher plate position can be assembled at a time. The assembly action includes multiple idle strokes such as picking up material, shifting grippers, dropping material, pressing, and resetting grippers. The production cycle is low and the overall machine mechanism has poor utilization rate, which is difficult to meet the needs of mass production of staple cartridges. It only changes the gripping to adsorption, so the problem of low assembly efficiency still exists. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an automatic assembly device for the staple cartridge of an intracavitary cutting stapler, which improves the assembly efficiency by enabling multiple staple cartridges to enter the assembly simultaneously through multi-station cyclic assembly.
[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automatic assembly device for an intracavitary stapler cartridge, comprising:
[0006] Workbench;
[0007] An assembly plate is rotatably mounted on the worktable. The assembly plate has multiple receiving grooves extending radially along its circumference to accommodate push pin assemblies. The outer radial end of each receiving groove has a discharge position, and the receiving groove has a discharge port below the discharge position. During the rotation of the assembly plate, the receiving groove has a filling position and an assembly position.
[0008] The filling assembly is provided on the workbench and is used to sequentially fill the pusher nail set into the receiving groove on the filling station.
[0009] A movable component is disposed on the workbench and located below the receiving slot at the corresponding assembly station. The movable component is used to clamp the staple cartridge and move the staple cartridge so that one of the pusher positions on the staple cartridge is aligned with the unloading port.
[0010] The pressing component, which is set on the workbench and corresponding to the moving component, is adapted to press down the push nail piece in the unloading position in the corresponding receiving groove to the push nail piece position that passes through the unloading port and is inserted into the nail magazine on the corresponding moving component when the receiving groove moves to the corresponding assembly station.
[0011] The assembly tray is provided with a feeding component corresponding to the receiving groove, and the feeding component is adapted to move the pusher pin in the receiving groove to the lower material position.
[0012] Furthermore, to quickly fill the receiving trough, the filling assembly includes:
[0013] A storage tray is rotatably mounted on the workbench. The storage tray has multiple storage slots extending radially along its circumference. The storage tray is adapted to be driven to rotate so that the storage slots have a feeding station and a discharging station. The storage slot located at the feeding station is adapted to be filled with push nail assembly.
[0014] When the storage tray is rotated to the discharge position, the pushing component is adapted to push the push pin assembly in the storage tank at the discharge position into the receiving trough at the filling position.
[0015] Furthermore, a baffle is provided on the workbench, and the inner wall of the baffle abuts against the outer wall of the storage tray to close the storage trough. The baffle is provided with a through groove corresponding to the storage trough at the feeding station and the storage trough at the discharging station. When the storage trough moves to the feeding station or the discharging station, the through groove aligns with the corresponding storage trough, thereby opening the storage trough.
[0016] Furthermore, the workbench is provided with a conveying assembly, which is adapted to push the pusher pin into the storage tank located at the feeding station.
[0017] Furthermore, a switch is provided at the discharge port, and the switch is slidably disposed on the assembly plate along the extension direction of the corresponding receiving groove. The switch is adapted to be moved to open or close the discharge port.
[0018] A blocking step is provided at the inlet of the receiving groove. When the feeding component pushes the pusher piece located in the receiving groove to move to the lower material position, the pusher piece at the lower material position abuts against the blocking step. The blocking step is used to restrict the pusher piece group within the corresponding receiving groove.
[0019] Furthermore, to ensure the timely filling of the push pin at the feeding port and guarantee smooth cyclic assembly, the feeding component includes:
[0020] A replenishing plate is slidably disposed in the corresponding receiving groove along the extending direction of the receiving groove. The replenishing plate has an outer position and an inner position. A driving member is provided on the replenishing plate. The driving member is adapted to be moved, thereby driving the replenishing plate to move. When the replenishing plate is moved to the outer position, the replenishing plate blocks the corresponding receiving groove. When the replenishing plate is moved to the inner position, the receiving groove is opened.
[0021] A reset assembly is disposed between the replenishing plate and the driving component, the reset assembly being adapted to move the replenishing plate from an inner position to an outer position.
[0022] Furthermore, the workbench is provided with a material replenishment drive component. The material replenishment drive component is adapted to move the drive component corresponding to the material receiving groove when the assembly plate rotates to the position of the material receiving groove at the filling station, thereby driving the material replenishment plate to move from the outer position to the inner position.
[0023] Furthermore, the pressing component includes a pressing drive cylinder disposed on the worktable and a pressing member disposed on the telescopic end of the pressing drive cylinder. The assembly plate has multiple pressing ports corresponding to the receiving grooves. The pressing ports are connected to the corresponding receiving grooves and are disposed in accordance with the unloading position.
[0024] Furthermore, a switch driving component is provided on the workbench. When the assembly tray is rotated to one of the receiving slots near the assembly station, the switch corresponding to the receiving slot contacts the switch driving component, and the switch driving component pushes the switch to move to open the corresponding unloading port.
[0025] A second elastic component is provided between the switch and the assembly plate, and the second elastic component is adapted to move the switch to close the feed port.
[0026] Furthermore, in order to better constrain the position of the pusher pin when it is inserted into the pusher pin position, a feeding plate is provided on the worktable. The feeding plate has a feeding channel that runs through it. The outlet of the feeding channel corresponds to the position of the pusher pin on the nail magazine held on the moving component. When one of the receiving slots is moved to the assembly station, the feeding port corresponding to the receiving slot corresponds to the inlet of the feeding channel.
[0027] By adopting the above technical solution, the present invention has the following beneficial effects:
[0028] Initially, there are no pusher pins in the receiving slots. When the assembly plate is rotated to the filling station position of one of the receiving slots, the pusher pin assembly is fed into the receiving slot. This receiving slot is the first receiving slot. Similarly, according to the order of their positions at the filling stations, the second, third, and fourth receiving slots are designated as such. As the assembly plate continues to rotate, when the first receiving slot moves to the assembly station, the pressing component at that assembly station presses a pusher pin located at the unloading position from the unloading port into the pusher pin position of the corresponding moving component's pin magazine. At this time, the second receiving slot is moved to the filling station and filled with the pusher pin assembly. With the assembly plate rotating again, the first receiving slot moves to the next assembly station for replenishment. Under the action of the component, the remaining two pusher pins are pushed to one of the pusher pins being located at the unloading position. The corresponding pressing component inserts the new pusher pin located at the unloading position into the corresponding pusher pin position. At this time, the second receiving groove is located at the previous assembly station for assembly work, while the third receiving groove is located at the filling station to be filled with the pusher pin set. The cycle of assembly stations is repeated to complete the cycle of assembly stations. The pin cartridges at multiple assembly stations can be assembled at the same time. After the pusher pins in the receiving grooves of all assembly stations are emptied, they will move again to the filling station to be filled with a new pusher pin set. The moving component will drive the pin cartridge to move to another empty pusher pin position below the unloading port after each pressing component works. Attached Figure Description

[0051] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0052] Example 1: As Figure 1-4 As shown, an automatic assembly device for an intracavitary stapler cartridge includes:
[0053] Workbench 1;
[0054] An assembly plate 2 is rotatably mounted on a workbench 1. The assembly plate 2 has multiple receiving grooves 21 extending radially along its circumference and used to accommodate push nail assemblies. The outer radial end of the receiving groove 21 is provided with a discharge position. The receiving groove 21 has a discharge port 22 below the discharge position. During the rotation of the assembly plate 2, the receiving groove 21 has a filling station 11 and an assembly station 12.
[0055] The packing assembly 3 is set on the workbench 1. The packing assembly 3 is used to sequentially fill the pusher nail set into the receiving groove 21 on the packing station.
[0056] A movable component 4 is set on the workbench 1 and located below the receiving groove 21 on the corresponding assembly station 12. The movable component 4 is used to clamp the nail cartridge and drive the nail cartridge to move so that one of the pusher nail positions on the nail cartridge is aligned with the unloading port 22.
[0057] The pressing component 5, which is set on the workbench 1 and is corresponding to the moving component 4, is adapted to press down the push nail piece in the corresponding material receiving groove 21 at the unloading position to the push nail piece position that passes through the unloading port 22 and is inserted into the nail chamber on the corresponding moving component 4 when the receiving groove 21 moves to the corresponding assembly station 12.
[0058] The assembly plate 2 is provided with a feeding component 6 corresponding to the receiving groove 21. The feeding component 6 is adapted to move the pusher piece in the receiving groove 21 to the lower material position.
[0059] It should be noted that, in this embodiment, the assembly plate 2 may be provided with four receiving slots 21, and correspondingly provided with one filling station 11 and three assembly stations 12. The three assembly stations 12 correspond to three moving components 4 respectively, which can simultaneously assemble three nail cartridges. The number of push nail pieces is the same as the number of assembly stations 12, so the push nail piece group consists of three push nail pieces.
[0060] In this embodiment, initially, there are no pusher pins in the receiving groove 21. When the assembly plate 2 is rotated to one of the receiving grooves 21 being located at the filling station 11, the pusher pin assembly is fed into the receiving groove 21. This receiving groove 21 is the first receiving groove, and so on, according to the order of its location at the filling station 11, they are the second, third, and fourth receiving grooves. As the assembly plate 2 continues to rotate, when the first receiving groove moves to the assembly station 12, the pressing component 5 at the assembly station 12 presses a pusher pin located at the unloading position from the unloading port 22 into the pusher pin position of the corresponding moving component 4. At this time, the second receiving groove is moved to the filling station 11 and filled with the pusher pin assembly. With the assembly plate 2 rotating again, the first receiving groove moves to the next assembly station. At position 12, under the action of the feeding component 6, the remaining two pusher pins are pushed to one of the pusher pins being located at the unloading position. The corresponding pressing component 5 inserts the newly located pusher pin into the corresponding pusher pin position. At this time, the second receiving groove is located at the previous assembly station 12 for assembly work, while the third receiving groove is located at the filling station 11 and is filled with the pusher pin group. The cycle of assembly station 12 is repeated to complete the cycle. The pin cartridges at multiple assembly stations 12 can be assembled at the same time. After the pusher pins in the receiving grooves 21 of all assembly stations 12 are emptied, they will move again to the filling station 11 for the filling of a new pusher pin group. The moving component 4 will drive the pin cartridge to move to another empty pusher pin position below the unloading port 22 after each pressing component 5 works.
[0061] Specifically, such as Figure 3 As shown, a first rotating assembly is provided on the worktable 1. The first rotating assembly includes a first driving gear 23 rotatably mounted on the worktable 1, a first driven gear 24 fixedly mounted on the assembly plate 2, and a first rotary motor 25 mounted on the worktable 1. The first driving gear 23 and the first driven gear 24 are meshed together, and the output end of the first rotary motor 25 is coaxially connected to the first driving gear 23.
[0062] In this embodiment, when the assembly disk 2 needs to rotate, the first rotary motor 25 is started to drive the first drive gear 23 to rotate, and the first driven gear 24 is driven to rotate by the first drive gear 23.
[0063] like Figure 5 As shown, the packing assembly 3 includes:
[0064] The storage tray 31 is rotatably set on the workbench 1. Multiple storage slots 32 extending radially along the circumference of the storage tray 31 are provided on the storage tray 31. The storage tray 31 is adapted to be driven to rotate so that the storage slots 32 have a feeding station 33 and a discharging station 34. The storage slots 32 located at the feeding station 33 are adapted to be filled with push nail pieces.
[0065] The pushing component 35, which is set on the workbench 1, is adapted to push the push nail plate group in the storage tank 32 located at the discharge station 34 into the receiving tank 21 located at the filling station 11 when the storage pan 31 is rotated to the position of the storage tank 32 located at the discharge station 34.
[0066] In this embodiment, a storage tray 31 is provided to improve the filling speed of the receiving trough 21. In the initial state, the storage troughs 32 are all empty, and the pusher pins can be filled into the storage troughs 32 in advance. The number of storage troughs 32 is greater than the number of receiving troughs 21 to ensure that the filling speed of the pusher pins in the receiving troughs 21 can meet the actual assembly speed. The pusher pins in the storage troughs 32 enter from the feeding station 33. When the storage tray 31 rotates to the position of the storage troughs 32 at the discharge station 34, the storage troughs 32 are aligned with the receiving troughs 21 at the filling station 11. At this time, the pushing component 35 works to push all the pusher pins in the storage troughs 32 into the receiving troughs 21, completing the filling of the receiving troughs 21. In actual production, all storage troughs 32 can be filled in advance, and then replenished sequentially.
[0067] Specifically, such as Figure 5 As shown, the pushing component 35 includes a pushing drive cylinder 36 installed on the workbench 1 and a pushing component 37 provided at the telescopic end of the pushing drive cylinder 36. The storage tray 31 has a plurality of pushing ports 38 that correspond to and communicate with the storage trough 32.
[0068] In this embodiment, when it is necessary to push the pusher pin assembly in the storage tank 32 into the corresponding receiving tank 21, the pusher drive cylinder 36 is activated and drives the pusher 37 through the pusher port 38, into the storage tank 32, and pushes the pusher pin assembly into the corresponding receiving tank 21.
[0069] It should be noted that the size of the pusher opening 38 is smaller than that of the storage tank 32 and the pusher pin, and the pusher pin cannot leave the storage tank 32 through the pusher opening 38.
[0070] Specifically, such as Figure 5 As shown, a second rotating assembly is provided on the worktable 1. The second rotating assembly includes a second driving gear 39 rotatably mounted on the worktable 1, a second driven gear 310 fixedly sleeved on the storage tray 31, and a second rotating motor 311 mounted on the worktable 1. The second driving gear 39 and the second driven gear 310 are meshed with each other, and the output end of the second rotating motor 311 is coaxially connected to the second driving gear 39.
[0071] In this embodiment, when it is necessary to control the rotation of the storage tray 31, the second rotary motor 311 is started to drive the second drive gear 39 to rotate, and the second drive gear 39 drives the second driven gear 310 to rotate.
[0072] Specifically, such as Figure 5 As shown, the storage tray 31 has multiple observation ports 312 corresponding to the storage tank 32, and an isolation plate 313 is provided between the observation port 312 and the storage tank 32.
[0073] In this embodiment, the number of pusher nails filled in the storage tank 32 can be directly observed through the observation port 312. After a specified number of pusher nails are filled, the storage tray 31 can be rotated to fill the next empty storage tank 32.
[0074] Furthermore, the isolation plate 313 is made of a transparent material, such as glass, so that the inside of the storage tank 32 can be observed through the observation port 312. A storage monitoring component is provided on the workbench 1. The storage monitoring component is located at the feeding station 33. The storage monitoring component is used to monitor the number of push nails in the storage tank 32 located at the feeding station 33 in real time.
[0075] Specifically, the material storage monitoring component is not shown in the figure. The material storage monitoring component can be an industrial camera. The industrial camera continuously takes pictures of the material storage tank 32 located at the feeding station 33 through the observation port 312. The controller analyzes the pictures and, after determining that a specified number of push nails have been filled into the material storage tank 32, the controller starts the second rotary motor 311 in the second rotary assembly to make the material storage tray 31 rotate.
[0076] like Figure 5 As shown, a baffle 314 is provided on the workbench 1. The inner wall of the baffle 314 abuts against the outer wall of the storage tray 31 to close the storage trough 32. The baffle 314 is provided with a through groove corresponding to the storage trough 32 at the feeding station 33 and the storage trough 32 at the discharging station 34. When the storage trough 32 moves to the feeding station 33 or the discharging station 34, the through groove aligns with the corresponding storage trough 32, thereby opening the storage trough 32.
[0077] In this embodiment, all storage tanks 32 except for the storage tanks 32 at the feeding station 33 and the discharging station 34 are blocked by the baffle 314, so that the pusher pieces in the storage tanks 32 that have been filled with pusher pieces cannot leave the storage tank 32 during the rotation of the storage tray 31.
[0078] like Figure 1 As shown, a conveying assembly 7 is provided on the workbench 1. The conveying assembly 7 is adapted to push the pusher pin into the storage tank 32 located at the feeding station 33.
[0079] In this embodiment, the pusher pieces are pushed one by one into the storage tank 32 located at the feeding station 33 by the conveying component 7. When a specified number of pusher pieces are detected to have entered the storage tank 32 located at the feeding station 33, the storage tray 31 is rotated to another storage tank 32 located at the feeding station 33.
[0080] Specifically, such as Figure 1-2 As shown, the conveying assembly 7 mainly includes a vibratory plate 71 and a linear vibratory guide rail 72. The vibratory plate 71 is installed on the workbench 1. One end of the linear vibratory guide rail 72 is connected to the discharge port of the vibratory plate 71, and the other end of the linear vibratory guide rail 72 is connected to the storage tank 32 located at the feeding station 33. The storage tank 31 is located between the assembly plate 2 and the linear vibratory guide rail 72.
[0081] In this embodiment, the pusher pieces are put into the vibratory feeder 71, and the vibratory feeder 71 arranges the pusher pieces in an orderly manner. Then, they are moved to the linear vibratory guide rail 72. The linear vibratory guide rail 72 will screen the pusher pieces that do not meet the standards and only allow the pusher pieces that meet the standards to enter the storage tank 32 located at the feeding station 33.
[0082] The vibratory plate 71 and the linear vibratory guide rail 72 are both existing technologies, and their specific structures and working principles will not be elaborated here.
[0083] like Figure 6 As shown, a switch 26 is provided at the discharge port 22. The switch 26 is slidably disposed on the assembly plate 2 along the extension direction of the corresponding receiving groove 21. The switch 26 is adapted to be moved to open or close the discharge port 22.
[0084] A blocking step 27 is provided at the inlet of the receiving groove 21. When the feeding component 6 pushes the pusher piece located in the receiving groove 21 to move to the lower material position, the pusher piece at the lower material position abuts against the blocking step 27. The blocking step 27 is used to restrict the pusher piece group within the corresponding receiving groove 21.
[0085] In this embodiment, the receiving groove 21 is not located at the assembly station 12, and the pusher pins do not need to be discharged through the discharge port 22. Therefore, the switch 26 is in the initial position, which closes the discharge port 22. When the receiving groove 21 is filled at the filling station 11, the pusher pin group is filled in. After the pusher pin group is completely entered into the receiving groove 21, the feeding component 6 works to apply a pushing force to the pusher pin group in the direction of the inlet of the receiving groove 21, so that the pusher pins at the discharge position abut against the blocking step 27. The blocking step 27, together with the feeding component 6, clamps the pusher pin group, preventing the pusher pin group from leaving the range of the receiving groove 21 or from constantly shaking in the receiving groove 21. The height of the blocking step 27 needs to be selected according to the size of the pusher pins in actual production to achieve a better limiting effect.
[0086] Example 2: Figure 7 As shown, this embodiment further includes the following structure based on embodiment one: the feeding component 6 includes:
[0087] A replenishing plate 61 is slidably disposed in the corresponding receiving groove 21 along the extending direction of the receiving groove 21. The replenishing plate 61 has an outer position and an inner position. A driving member 62 is disposed on the replenishing plate 61. The driving member 62 is adapted to be moved by action, thereby driving the replenishing plate 61 to move. When the replenishing plate 61 is moved to the outer position, the replenishing plate 61 blocks the corresponding receiving groove 21. When the replenishing plate 61 is moved to the inner position, the receiving groove 21 is opened.
[0088] A reset assembly 63 is disposed between the feeding plate 61 and the driving component 62. The reset assembly 63 is adapted to drive the feeding plate 61 to move from the inner position to the outer position.
[0089] In this embodiment, when the empty receiving trough 21 is moved to the filling station 11, the corresponding replenishing plate 61 is initially located on the outer side (i.e., the initial position). At this time, the receiving trough 21 is closed. To facilitate the unobstructed entry of the pusher pin assembly in the storage tank 32 into the receiving trough 21, the driving member 62 needs to be moved away from the storage tank 32, thereby driving the replenishing plate 61 to move inward. When the replenishing plate 61 moves to the inner position, the receiving trough 21 is fully opened. At this time, the pusher pin assembly in the storage tank 32 is pushed into the fully opened receiving trough 21 by the pushing member 35. After the pusher pin assembly is filled, the driving member 62 is released. After the driving member 62 loses the force actively applied, the replenishing plate 61 passes through... The reset assembly 63 moves from the inner position to the outer position. During the movement, it works with the blocking step 27 to limit the pusher piece group. When the receiving slot 21 filled with the pusher piece group is moved to the assembly station 12, the discharge port 22 opens. The pressing component 5 inserts a single pusher piece located at the discharge position through the discharge port 22 into the pusher piece position of the corresponding nail chamber. After completing a single insertion assembly, the pressing component 5 resets. Since the pusher piece at the original discharge position is pushed out, a gap is created. At this time, the replenishing plate 61 continues to move to the outer position under the drive of the reset assembly 63, so that the next pusher piece in the pusher piece group is located at the discharge position and abuts against the blocking step 27, so that it can be pushed out when moving to the next assembly station 12 for assembly.
[0090] Specifically, such as Figure 7The reset assembly 63 includes a connecting rod 64 and a reset spring 65. The connecting rod 64 passes through the assembly plate 2 and extends into the corresponding receiving groove 21. The connecting rod 64 is slidably disposed on the assembly plate 2. The two ends of the connecting rod 64 are respectively connected to the corresponding driving component 62 and the corresponding feeding plate 61. The reset spring 65 is located outside the assembly plate 2 and is sleeved on the outside of the connecting rod 64. The two ends of the reset spring 65 are respectively connected to the assembly plate 2 and the corresponding driving component 62.
[0091] In this embodiment, when the feeding plate 61 is in the outer position, the return spring 65 is in the natural state. When the driving member 62 is moved away from the storage tank 32, the feeding plate 61 moves from the outer position to the inner position, the connecting rod 64 moves synchronously, and the return spring 65 is stretched. When the push nail assembly is fully inserted, the action on the driving member 62 is released, and the feeding plate 61 is reset by the contraction of the return spring 65 and moves to the outer position, thereby cooperating with the blocking step 27 to limit the push nail assembly.
[0092] like Figure 8 As shown, a feeding drive component 66 is provided on the workbench 1. The feeding drive component 66 is adapted to move the drive component 62 corresponding to the receiving groove 21 when the assembly plate 2 rotates to the position of the receiving groove 21 at the filling station 11, thereby driving the feeding plate 61 to move from the outer position to the inner position.
[0093] In this embodiment, when the empty receiving trough 21 is moved to the filling station 11, the replenishing plate 61 is in the outer position, and the pusher pin assembly cannot enter the receiving trough 21 without obstruction. At this time, the replenishing drive component 66 is activated and drives the drive component 62 to move away from the storage trough 32, so that the replenishing plate 61 moves to the inner position, thereby fully opening the receiving trough 21.
[0094] Specifically, such as Figure 8 As shown, the feeding drive component 66 includes a feeding drive cylinder 67 mounted on the workbench 1 and a docking plate 68 disposed on the telescopic end of the feeding drive cylinder 67. When the receiving trough 21 is moved to the filling station 11, the docking plate 68 is adapted to connect with the drive component 62 corresponding to the receiving trough 21. At this time, starting the feeding drive cylinder 67 drives the docking plate 68 to move away from the storage trough 32, which in turn drives the drive component 62 to move. When the assembly plate 2 rotates to the receiving trough 21 where the push nail assembly is filled and moves to the assembly station 12, the drive component 62 is disengaged from the docking plate, thus releasing the restriction on the drive component 62.
[0095] Specifically, such as Figure 9-10 As shown, the pressing component 5 includes a pressing drive cylinder 51 set on the workbench 1 and a pressing component 52 set on the telescopic end of the pressing drive cylinder 51. The assembly plate 2 has multiple pressing ports 53 corresponding to the receiving grooves 21. The pressing ports 53 are connected to the corresponding receiving grooves 21 and are set to the corresponding material feeding positions.
[0096] In this embodiment, when the receiving groove 21 containing the pusher pin is moved to the assembly station 12, the pressing component 5 operates. The pressing drive cylinder 51 drives the pressing component 52 to move through the pressing port 53 and into the receiving groove 21, where it contacts a single pusher pin at the unloading position. Under continuous movement, the pusher pin is pushed through the corresponding unloading port 22 to leave the assembly plate 2 and is inserted into the pusher pin position of the pin magazine at the corresponding assembly station 12. After assembly is completed, the pressing drive cylinder 51 drives the pressing component 52 to move in the opposite direction to reset. After the pressing component 52 is reset, under the action of the replenishing plate 61, the next pusher pin is pushed to the unloading port 22, ready for the next assembly operation.
[0097] It should be noted that when the pressing member 52 pushes the pusher piece out of the feeding port 22 and presses it into the pusher piece position, the pressing member 52 has a sealing effect on the receiving groove 21 above the feeding port 22. At this time, the pusher piece adjacent to the pressing member 52 cannot be moved to the feeding position.
[0098] Specifically, such as Figure 11 As shown, the workbench 1 is provided with a plurality of positioning elements 28. The positioning elements 28 are adapted to abut against the corresponding driving element 62 to restrict the movement of the driving element 62 when the receiving groove 21 is moved to the assembly station 12.
[0099] It should be noted that the different positioning parts 28 are in different positions at the corresponding assembly station 12. When the positioning part 28 and the receiving groove 21 move to the assembly station 12, the actual position of the corresponding driving part 62 is matched.
[0100] In this embodiment, when the receiving groove 21 moves to the assembly station 12, the corresponding positioning member 28 limits the corresponding driving member 62 to prevent the feeding plate 61 from continuously applying a downward pushing force to the pusher piece in the corresponding receiving groove 21. This reduces the resistance of the pressing member 52 in pushing the pusher piece out of the unloading position. When the pressing member 52 resets after pushing out the pusher piece, if there are still other pusher pieces in the corresponding receiving groove 21, this setting can reduce the friction between the pressing member 52 and the adjacent pusher pieces when resetting. If there are no pusher pieces in the corresponding receiving groove 21, this setting can reduce the friction between the pressing member 52 and the adjacent feeding plate 61 when resetting.
[0101] Example 3: Figure 12-14 As shown, this embodiment further includes the following structure based on embodiment one: a switch driving component 29 is provided on the workbench 1. When the assembly tray 2 is rotated to one of the receiving slots 21 and close to the assembly station 12, the switch component 26 corresponding to the receiving slot 21 contacts the switch driving component 29, and the switch driving component 29 pushes the switch component 26 to move to open the corresponding unloading port 22.
[0102] A second elastic component 210 is provided between the switch element 26 and the assembly plate 2. The second elastic component 210 is adapted to drive the switch element 26 to move to close the feed port 22.
[0103] In this embodiment, the discharge port 22 corresponding to the receiving groove 21 is closed before entering the assembly station 12 for assembly work. When the receiving groove 21 is moved to the assembly station 12, the switch 26 partially contacts the switch driving component 29. The switch driving component 29 pushes the switch 26 to open the discharge port 22 and squeezes the second elastic component 210. When the receiving groove 21 is moved to a position other than the assembly station 12, the switch plate loses contact with the switch driving component 29 and moves in the opposite direction to the reset position through the second elastic component 210, and closes the discharge port 22.
[0104] Specifically, such as Figure 13 As shown, the switch drive component 29 includes an inclined portion 211 and a positioning portion 212. When the receiving groove 21 moves toward the assembly station 12, the switch component 26 first contacts the inclined portion 211, causing the switch component 26 to move in the opposite direction away from the discharge port 22 along the inclined angle of the inclined portion 211, thereby opening the discharge port 22. When the switch component 26 contacts the positioning portion 212, the discharge port 22 is fully opened.
[0105] Specifically, such as Figure 13 As shown, the second elastic component 210 includes a second telescopic rod and a second telescopic spring. The two ends of the second telescopic rod are respectively connected to the switch component 26 and the assembly plate 2. The second telescopic spring is sleeved outside the second telescopic rod, and the two ends of the second telescopic spring are respectively connected to the switch component 26 and the assembly plate 2.
[0106] In this embodiment, when the switch 26 is moved away from the switch 26, the second telescopic spring is compressed. When the switch 26 loses contact with the switch drive component 29, the second telescopic spring returns to its natural state and drives the switch 26 to move in the opposite direction to the reset state, thereby closing the feed port 22.
[0107] like Figure 12-14 As shown, a feeding plate 9 is provided on the workbench 1. A feeding channel 91 is provided through the feeding plate 9. The outlet of the feeding channel 91 corresponds to the position of the push pin on the pin magazine held on the moving component 4. When one of the receiving grooves 21 is moved to the assembly station 12, the feeding port 22 corresponding to the receiving groove 21 corresponds to the position of the inlet of the feeding channel 91.
[0108] In this embodiment, when the receiving groove 21 is moved to the assembly station 12, the corresponding unloading port 22 is aligned with the inlet of the unloading channel 91 of the unloading plate 9, and the outlet of the unloading channel 91 is aligned with the empty pusher pin position. The pressing member 52 is moved to pass through the unloading port 22 and the unloading channel 91 in sequence, pressing the pusher pin into the corresponding pusher pin position. There is a slight gap between the outlet of the unloading channel 91 and the pin magazine. During the pressing process, the pusher pin is restricted by the unloading channel 91 to prevent the pusher pin from shifting position during the assembly process.
[0109] Specifically, such as Figure 12 As shown, the moving component 4 includes a clamping component 41, an X-axis electrically controlled slide rail 42, and a Y-axis electrically controlled slide rail 43. The moving end of the Y-axis electrically controlled slide rail 43 is connected to the outer shell of the X-axis electrically controlled slide rail 42, and the moving end of the X-axis electrically controlled slide rail 42 is connected to the outer shell of the clamping component 41.
[0110] In this embodiment, the staple cartridge is clamped by the clamping component 41, and then the pusher plate above the staple cartridge is moved to correspond to the outlet of the unloading channel 91 by the setting of the X-axis electrically controlled slide rail 42 and the Y-axis electrically controlled slide rail 43.
[0111] It should be noted that the clamping component 41, the X-axis electrically controlled slide rail 42, and the Y-axis electrically controlled slide rail 43 are all existing technologies. Their specific structures and working principles will not be elaborated here, as long as they can achieve the corresponding functions.
[0112] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
