[0029] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0030] See also Figure 1 and Figure 2 The embodiment of the present application provides an assembly device 100, which includes a carrying mechanism 100a, a clamping mechanism 100b and a rotating mechanism 100c. The assembly device 100 is used to assemble a knife handle 200. The knife handle 200 includes a shank 210, a collet 220 and a nut 230.
[0031] In order to facilitate understanding and explanation of the embodiments of the present application, a three-dimensional coordinate system is established in some drawings, and the first direction is Figure 1 The Z-axis direction shown, the second direction is Figure 1 The X-axis direction is shown, and the third direction is Figure 1 In the Y-axis direction shown, the first direction, the second direction, and the third direction are perpendicular to each other.
[0032] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4The carrier mechanism 100a includes a first carrier assembly 10 and a second carrier assembly 20. The first carrier assembly 10 is used to carry the nut 230. The second carrier assembly 20 is spaced apart from the first carrier assembly 10 and is used to carry the collet 220. The clamping mechanism 100b includes a clamping assembly 30, a lifting member 40, and a sliding member 50. The clamping assembly 30 is used to clamp the nut 230 and is slidably connected to the lifting member 40 in a first direction. The sliding member 50 is slidably connected to the lifting member 40 in a second direction. The sliding member 50 is configured to drive the clamping assembly 30 to clamp the nut 230 from the first carrier assembly 10 and move it toward the second carrier assembly 20. The lifting member 40 is configured to drive the clamping assembly 30 to move in the first direction toward the second carrier assembly 20, so that the nut 230 descends and engages the collet 220 to form a nut assembly. The rotating mechanism 100c includes a supporting assembly 60, a rotating member 70, a movable member 80, a first elastic member 90, and a rotating drive member 110. The supporting assembly 60 is spaced apart from the second bearing assembly 20 and is used to support the knife handle 210 so that the clamping mechanism 100b can be placed and press the nut assembly onto the knife handle 210. The rotating member 70 and the bearing assembly are spaced apart along the first direction, and one end of the movable member 80 is movably inserted into the rotating member 70, and the other end of the movable member 80 is connected to the supporting assembly 60. The first elastic member 90 is sleeved on the movable member 80, and the two ends of the first elastic member 90 elastically abut against the rotating member 70 and one end of the movable member 80 adjacent to the supporting assembly 60. The rotating driving member 110 is connected to the rotating member 70 and is used to drive the rotating member 70 to drive the knife handle 210 on the supporting assembly 60 to rotate, so that the first elastic member 90 elastically resets and pushes the supporting assembly 60 to drive the knife handle 210 to rise, thereby causing the knife handle 210 to be threadedly connected to the nut assembly to assemble the knife handle 200. For example, the lifting member 40 and the sliding member 50 may be a servo slide, a cylinder, etc., the first elastic member 90 may be a spring, an elastic sleeve, etc., and the rotary driving member 110 may be a motor, a rotary cylinder, etc. The sliding member 50 and the supporting assembly 60 are spaced apart along the third direction.
[0033] When the assembly device 100 is in use, first, the clamping assembly 30 clamps the nut 230 on the first carrier assembly 10, and the sliding member 50 drives the clamping assembly 30 to move to the second carrier assembly 20; then, the lifting member 40 drives the nut 230 to move downward toward the second carrier assembly 20, so that the nut 230 is precisely engaged with the collet 220 on the second carrier assembly 20 to form a nut assembly; then, the sliding member 50 drives the clamping assembly 30 holding the nut assembly to move to the supporting assembly 60, and the lifting member 40 The clamping assembly 30, which holds the nut assembly, is driven downward toward the support assembly 60, allowing the handle 210 to stably receive the nut assembly. Simultaneously, the nut assembly descends, squeezing the handle 210 to a predetermined position and causing the support assembly 60 to descend and compress the first elastic member 90 to a predetermined position. Finally, the rotating drive member 110 drives the rotating member 70 to rotate the handle 210 on the support assembly 60. At this point, the first elastic member 90 elastically returns to its original position, pushing the support assembly 60 upward and causing the handle 210 to be threadedly connected to the nut assembly. In this manner, the supporting mechanism 100a, clamping mechanism 100b, and rotating mechanism 100c coordinate with each other to quickly and accurately complete the assembly of the handle 200, thereby improving assembly efficiency and precision.
[0034] It can be understood that the movable member 80 is connected to the supporting assembly 60 , and the supporting assembly 60 can drive the end of the movable member 80 to compress the first elastic member 90 .
[0035] See also Figure 2 and Figure 3 In some embodiments, the clamping assembly 30 includes a support plate 31, a clamping driver 32, and two clamping blocks 33. The support plate 31 is slidably connected to the lifting member 40 along a first direction, and the clamping driver 32 is connected to the support plate 31. The two clamping blocks 33 are spaced apart and are both connected to the clamping driver 32. The clamping driver 32 is configured to drive the two clamping blocks 33 to clamp the nut 230. For example, the clamping driver 32 can be a bidirectional telescopic cylinder.
[0036] In this way, through the above setting, the clamping drive 32 drives the two clamping blocks 33 to clamp the two sides of the nut 230 to ensure that the clamping assembly 30 stably clamps the nut 230, preventing the nut 230 from loosening or falling during movement and assembly, thereby improving the assembly stability.
[0037] Please continue reading Figure 2 and Figure 3In some embodiments, the clamping mechanism 100b further includes a connecting frame 120, a stopper driver 130, and two stopper assemblies 140. The connecting frame 120 is connected to the support plate 31, and the stopper driver 130 is disposed on the connecting frame 120. The two stopper assemblies 140 are respectively connected to the stopper driver 130, and the stopper driver 130 is used to drive the two stopper assemblies 140 to abut against the two sides of the nut 230. For example, the stopper driver 130 can be a bidirectional telescopic cylinder.
[0038] In this way, through the above setting, the stop drive 130 drives the two stop assemblies 140 to abut against the two sides of the nut 230 to prevent the nut 230 from rotating during the assembly process, ensuring the stable assembly of the nut assembly and the shank 210, and further improving the assembly stability.
[0039] See also Figure 3 In some embodiments, the clamping mechanism 100b further includes a connecting plate 150, a supporting member 160, and two guide members 170. The connecting plate 150 is vertically connected to the support plate 31. The supporting member 160 is disposed between the two clamping blocks 33 and connected to the connecting plate 150. The supporting member 160 is used to abut the end surface of the nut 230. The two guide members 170 are respectively disposed between the two stopper assemblies 140 and connected to both ends of the connecting plate 150. The stopper assemblies 140 sequentially pass through a guide member 170 and a clamping block 33 located on the same side to abut the nut 230.
[0040] In this manner, the abutment member 160 abuts against the end surface of the nut 230 to the handle 210, thereby limiting the vertical freedom of the nut 230 during assembly. This prevents the nut 230 from loosening up and down, which could lead to thread slippage and misalignment during the threaded assembly of the handle 210 and the nut 230, thereby ensuring a stable connection between the nut 230 and the handle 210, thereby improving assembly stability. Furthermore, by providing the aforementioned guide member 170, the guide member 170 can guide the movement direction of the stopper assembly 140, ensuring that the two stopper assemblies 140 stably abut against both sides of the nut 230, thereby ensuring that the stopper assembly 140 stably stops the rotation of the nut 230 during assembly.
[0041] See also Figure 5In some embodiments, the stop assembly 140 includes a mounting base 141, a stop rod 142, a second elastic member 143, and a movable plate 144. The movable plates 144 of the two stop assemblies 140 are respectively connected to the two ends of the stop driving member 130 to form a U-shape. Optionally, the movable plate 144 is L-shaped. The front and rear surfaces of the mounting base 141 respectively have a protrusion and a closing groove 1411, and the protrusion is embedded in one end of the movable plate 144. One end of the stop rod 142 passes through a guide member 170 and a clamping block 33 located on the same side in sequence to abut against the nut 230, and the other end of the stop rod 142 abuts against the groove wall of the closing groove 1411 through the second elastic member 143. Specifically, the two ends of the second elastic member 143 elastically abut the stop rod 142 and the groove wall of the closing groove 1411 respectively. Exemplarily, the second elastic member 143 can be a spring.
[0042] In this way, the stop drive 130 drives the movable plates 144 of the two stop assemblies 140 to open and close, so that the stop rod 142 abuts against the side wall of the nut 230, and compresses the second elastic member 143 to the groove wall of the closing groove 1411, thereby forming a flexible contact between the stop rod 142 and the nut 230, preventing the stop rod 142 from excessively abutting against the nut 230 and causing damage to the stop assembly 140 and the nut 230.
[0043] It is understandable that the side wall of the nut 230 may be provided with a slot (not shown), and the stop rod 142 is inserted into the slot under the drive of the stop driving member 130 and abuts against the bottom of the slot.
[0044] See also Figure 4 In some embodiments, the supporting assembly 60 includes a supporting base 61 and a snap-fit buckle 62. The supporting base 61 is provided with a through hole 611. The snap-fit buckle 62 is provided on one side of the through hole 611 and is connected to the supporting base 61, and the snap-fit buckle 62 is used to snap-fit the knife handle 210 inserted in the through hole 611. Exemplarily, the snap-fit buckle 62 can be any snap-fit body, snap-fit portion or similar snap-fit block that can snap-fit the knife handle 210. Optionally, the supporting base 61 includes a first supporting plate 612 and a second supporting plate 613 that are stacked, the through hole 611 passes through the first supporting plate 612 and the second supporting plate 613, the first supporting plate 612 is connected to the movable part 80, and the two snap-fit buckles 62 are distributed on the second supporting plate 613.
[0045] In this way, through the above-mentioned setting, the supporting base 61 stably supports the knife handle 210, and the knife handle 210 is clamped by the snap buckle 62, so that the knife handle 210 maintains its placement position during the assembly process, ensuring that the knife handle 210 and the nut assembly are stably connected during the subsequent assembly process, thereby improving the assembly stability.
[0046] See also Figure 6In some embodiments, the first bearing assembly 10 and the second bearing assembly 20 each include a fixed seat 11, a bearing seat 12, a third elastic member 13 and a stop sleeve 14, wherein the number of the third elastic members 13 is multiple. The fixed seat 11 is spaced apart from the rotary drive member 110, and the fixed seat 11 is provided with a receiving groove 111. The bearing seat 12 is movably inserted into the receiving groove 111, and the bearing seat 12 has a bearing protrusion 121 adapted to the nut 230, and the bearing protrusion 121 is provided with a positioning hole 122 adapted to the collet 220. Multiple third elastic members 13 are distributed in the receiving groove 111 at intervals, and the two ends of each third elastic member 13 elastically abut against the bottom of the receiving groove 111 and the bearing seat 12 respectively. The stop sleeve 14 is sleeved on the bearing protrusion 121 and locked to the fixed seat 11 to press the bearing seat 12 tightly against the receiving groove 111.
[0047] In this way, the bearing seat 12 positions the nut 230 through the bearing protrusion 121, so that the first bearing component 10 stably carries the nut 230, and positions the collet 220 through the positioning hole 122, so that the second bearing component 20 stably carries the collet 220, thereby realizing the bearing function of the first bearing component 10 and the second bearing component 20; when the collet 220 or the nut 230 is placed on the bearing seat 12, the bearing seat 12 compresses the third elastic member 13 to the bottom of the receiving groove 111, so that the bearing seat 12 flexibly receives the nut 230 or the collet 220, avoiding damage to the nut 230 or the collet 220 due to rigid contact with the bearing seat 12, thereby improving the assembly quality.
[0048] Optionally, the receiving slot 111 is provided with a plurality of shallow grooves 1111 and a positioning protrusion 1112. The plurality of shallow grooves 1111 are distributed on the bottom wall of the receiving slot 111 around the positioning protrusion 1112. The plurality of shallow grooves 1112 correspond one-to-one with the plurality of third elastic members 13. The size of the shallow grooves 1111 matches the end portions of the third elastic members 13. The support seat 12 is movably inserted into the receiving slot 111 to press the third elastic members 13 into the shallow grooves 1111. The positioning protrusion 1112 corresponds to the positioning hole 122 to support the collet 220 when the collet 220 is inserted into the positioning hole 122.
[0049] See also Figure 4 In some embodiments, the support assembly 60 is disposed between the first support assembly 10 and the second support assembly 20, and the rotation mechanism 100c further includes a signal transmitter 180 and a signal receiver 181. The signal transmitter 180 is disposed on the first support assembly 10 and is configured to transmit signals. The signal receiver 181 is disposed on the second support assembly 20 and is configured to determine the position of the support assembly 60 based on the received transmitted signal (i.e., whether the support assembly 60 is obscured). For example, the signal transmitter 180 may be an infrared transmitter, and the signal receiver 181 may be an infrared receiver.
[0050] In this way, through the above-mentioned setting, the signal receiver 181 can receive the signal sent by the signal transmitter 180, realize real-time detection of the position of the supporting assembly 60, and after determining that the supporting assembly 60 has moved to the initial height, the signal receiver 181 sends an electrical signal to the rotating drive member 110 to stop the rotating drive member 110 from driving the supporting assembly 60 to rotate, so as to assemble the nut assembly to the preset position of the shank 210, thereby controlling the tightness of the nut assembly assembly, realizing precise assembly of the shank 200, and improving the assembly accuracy.
[0051] Optionally, the diameter of the first supporting plate 612 is larger than the diameter of the second supporting plate 613 and the diameter of the knife handle 210, so as to block the signal transmitted by the signal transmitter 180. Specifically, when the supporting assembly 60 is at the initial height, the signal transmitter 180, the signal receiver 181, and the first supporting plate 612 of the supporting assembly 60 are at the same horizontal position. The position of the first supporting plate 612 near the edge blocks the signal transmitted by the signal transmitter 180, resulting in the signal receiver 181 not being able to receive the signal transmitted by the transmitter 180. At this time, it can be determined that the first supporting plate 612 is at the initial height. When the nut assembly descends and squeezes the tool handle 210, causing the first supporting plate 612 of the supporting assembly 60 to be squeezed and lowered together to compress the first elastic member 90, the first supporting plate 612 descends from its initial height and is no longer at the same horizontal position as the signal transmitter 180. Since the diameter of the second supporting plate 613 or the diameter of the tool handle 210 is smaller than the diameter of the first supporting plate 612, the signal transmitted by the signal transmitter 180 is not blocked, so that the signal receiver 181 can receive the signal transmitted by the signal transmitter 180. Based on this, the assembly device 100 can determine that the first supporting plate 612 has descended. In view of this, the signal transmitter 180 receives an electrical signal to the driving member 110, so that the driving member 110 drives the rotating member 70 to move. The knife handle 210 on the dynamic support assembly 60 rotates so that the first elastic member 90 elastically resets to push the first support plate 612 of the support assembly 60 back to its initial height, and the knife handle 210 is rotated and assembled to the preset position of the nut assembly. The first support plate 612 is reset, and the position of the first support plate 612 close to the edge blocks the signal emitted by the signal transmitter 180, causing the signal receiver 181 to fail to receive the signal emitted by the transmitter 180 again. At this time, it can be determined that the first support plate 612 has returned to its initial height and the nut assembly has been assembled to the preset position of the knife handle 210. Then, the signal receiver 181 sends an electrical signal to the rotating drive member 110 to stop the rotating drive member 110 from driving the support assembly 60 to rotate.
[0052] Optionally, the driving member 110 drives the nut assembly to rotate and assemble with the handle 210 to mainly realize the rotational connection between the external thread of the nut 230 of the nut assembly and the internal thread of the handle 210. The height of the rotational connection point between the external thread of the nut 230 of the nut assembly and the internal thread of the handle 210 can be equal to or differ by ±1 cm from the reset height of the first elastic member 90.
[0053] See also Figure 1 and Figure 7 In some embodiments, the assembly device 100 further includes a transfer mechanism 100d, a workbench 100e, and two support frames 100f. The first carrying assembly 10, the second carrying assembly 20, the sliding member 50, the rotating member 70, and the two support frames 100f are spaced apart on the workbench 100e. The transfer mechanism 100d includes a first driving member 191, a second driving member 192, three removal assemblies 193, and a linkage plate 1931. The two support frames 100f support the first driving member 191, and the second driving member 192 is slidably connected to the first driving member 191. The linkage plate 1931 is provided on the second driving member 192 for connecting the removal assembly 193. The three removal assemblies 193 are respectively a first removal assembly 1932, a second removal assembly 1933, and a third removal assembly 1934. The first removal assembly 1932, the second removal assembly 1933, and the third removal assembly 1934 are arranged at intervals along the horizontal direction and are all connected to the linkage plate 1931. The first removal assembly 1932, the second removal assembly 1933, and the third removal assembly 1934 are used to respectively remove the collet 220, the tool handle 210, and the nut 230. For example, the first driving member 191 and the second driving member 192 can be a cylinder, a servo slide, etc., and the first removal assembly 1932, the second removal assembly 1933, and the third removal assembly 1934 can be any removal part, removal plate, or removal clamping jaw capable of respectively removing the nut 230, the tool handle 210, and the collet 220, such as a pneumatic clamping jaw.
[0054] In this way, the transfer mechanism 100d removes the collet 220, the shank 210 and the nut 230 respectively through the first removal component 1932, the second removal component 1933 and the third removal component 1934, and can accurately align and remove the corresponding components, effectively avoiding position deviations in the process of removing the various components of the handle 200, reducing the shaking or offset of the various components of the handle 200 during the transfer process, thereby improving the accuracy and stability of assembly.
[0055] See also Figure 8 The embodiment of the present application also provides an assembly method for assembling a knife handle 200, which includes a knife handle 210, a collet 220 and a nut 230, and is applied to the above-mentioned assembly device 100. The assembly device 100 has a controller (not shown in the figure). The assembly method specifically includes the following steps, which can be controlled by the controller.
[0056] S10 , controlling the clamping assembly 30 to clamp the nut 230 on the first bearing assembly 10 , and controlling the sliding member 50 to drive the clamping assembly 30 to move to the second bearing assembly 20 .
[0057] Specifically, the clamping assembly 30 is controlled to stably clamp the nut 230 to prevent the nut 230 from falling during the transfer process, and then the sliding member 50 is controlled to move the nut 230 to the second supporting assembly 20, so that the nut 230 clamped by the clamping assembly 30 corresponds to the collet 220 carried by the second supporting assembly 20, which facilitates the subsequent clamping operation of the nut 230 and the collet 220.
[0058] S20 , controlling the lifting member 40 to drive the nut 230 to descend and move close to the second bearing assembly 20 , so that the nut 230 is engaged with the collet 220 on the second bearing assembly 20 to form a nut assembly.
[0059] Specifically, the control lift 40 controls the descending height of the nut 230 to ensure that the nut 230 can be accurately engaged with the collet 220 to form a stable nut assembly, thereby avoiding assembly failure caused by unstable connection between the nut 230 and the collet 220.
[0060] S30, control the sliding member 50 to drive the clamping assembly 30 clamping the nut assembly to move to the supporting assembly 60, and control the lifting member 40 to drive the nut assembly to descend close to the supporting assembly 60, so that the tool handle 210 receives the nut assembly, and the supporting assembly 60 descends to compress the first elastic member 90.
[0061] Specifically, the sliding member 50 is controlled to drive the clamping assembly 30 to move to the supporting assembly 60, so that the nut assembly corresponds to the tool handle 210, so that the tool handle 210 can accurately correspond to the nut assembly, and then the lifting member 40 is controlled to drive the nut assembly to descend close to the supporting assembly 60. The supporting assembly 60 descends to a predetermined position under the squeezing of the tool handle 210 by the nut assembly, and further compresses the first elastic member 90 to a certain position, so that the tool handle 210 and the nut assembly can adapt to the slight tolerance between the two during the docking process, so that the tool handle 210 and the nut assembly form a flexible docking, and at the same time, the compressed first elastic member 90 can provide elastic potential energy in the subsequent assembly process, which is beneficial to the assembly operation of the tool handle 210 and the nut assembly.
[0062] S40, control the rotating driving member 110 to drive the rotating member 70 to drive the knife handle 210 on the supporting assembly 60 to rotate, and at the same time the first elastic member 90 elastically resets to push the supporting assembly 60 to drive the knife handle 210 to rise, so that the knife handle 210 is threadedly connected to the nut assembly to assemble to form the knife handle 200.
[0063] Specifically, the handle 210 is driven to rotate by the rotating driving member 110, and the elastic reset pushes the handle 210 upward, thereby achieving a quick and precise threaded connection between the handle 210 and the nut assembly without manual tightening, thereby improving assembly and precision efficiency and reducing manual labor intensity and operation risks.
[0064] Thus, by executing the above steps, first, the clamping assembly 30 clamps the nut 230 on the first carrier assembly 10, and the sliding member 50 drives the clamping assembly 30 to move to the second carrier assembly 20; then, the lifting member 40 drives the nut 230 to move downward and close to the second carrier assembly 20, so that the nut 230 is precisely engaged with the collet 220 on the second carrier assembly 20 to form a nut assembly; then, the sliding member 50 drives the clamping assembly 30 holding the nut assembly to move to the supporting assembly 60, and the lifting member 40 drives the nut 230 to move downward and close to the second carrier assembly 20, so that the nut 230 is precisely engaged with the collet 220 on the second carrier assembly 20 to form a nut assembly; The clamping assembly 30, which holds the nut assembly, descends toward the supporting assembly 60, allowing the handle 210 to stably receive the nut assembly. Simultaneously, the nut assembly descends, squeezing the handle 210 to a predetermined position and causing the supporting assembly 60 to descend and compress the first elastic member 90 to a predetermined position. Finally, the rotary drive member 110 drives the rotating member 70 to rotate the handle 210 on the supporting assembly 60. At this point, the first elastic member 90 elastically resets, pushing the supporting assembly 60 upward to thread the handle 210 into the nut assembly. In this manner, the supporting mechanism 100a, the clamping mechanism 100b, and the rotating mechanism 100c coordinate with each other to quickly and accurately complete the assembly of the handle 200, thereby improving assembly efficiency and precision.
[0065] See also Figure 8 In another embodiment, the following steps are further included before step S10.
[0066] S00, control the first driving member 191 and the second driving member 192 to drive the first removing assembly 1932, the second removing assembly 1933 and the third removing assembly 1934 to respectively clamp the nut 230, the tool handle 210 and the collet 220 from the raw material position, and move and install them on the first supporting assembly 10, the supporting assembly 60 and the second supporting assembly 20 respectively.
[0067] In this way, by executing the above steps, the three sets of removal components 193 are accurately driven by the first driving member 191 and the second driving member 192 to ensure that the nut 230, the tool handle 210 and the collet 220 are accurately clamped from the raw material position, and are respectively installed on the first supporting component 10, the supporting component 60 and the second supporting component 20 for subsequent assembly operations.
[0068] See also Figure 8 In another embodiment, step S40 further includes the following steps.
[0069] S50, controlling the first driving member 191 and the second driving member 192 to drive the second removing assembly 1933 to clamp the assembled knife handle 200 from the supporting assembly 60, and move it to the clinker position.
[0070] In this way, by executing the above steps, after completing the assembly of the knife handle 200, the first driving member 191 and the second driving member 192 drive the second removal component 1933 to promptly transfer the assembled knife handle 200 from the supporting component 60 to the clinker position, thereby realizing the transfer operation of the knife handle 200 and facilitating centralized processing.
[0071] See also Figure 9 In some embodiments, step S40 includes the following steps.
[0072] Step S41 , controlling the rotary driving member 110 to drive the rotary member 70 to rotate, and at the same time, the first elastic member 90 elastically resets to push the supporting assembly 60 to drive the knife handle 210 to rise.
[0073] Specifically, the rotating driving member 110 drives the rotating member 70 to rotate, and the first elastic member 90 elastically resets and pushes the supporting assembly 60 to rise, which effectively improves the assembly efficiency, shortens the assembly time, and realizes the rapid threaded connection between the shank 210 and the nut assembly.
[0074] Step S42 , controlling the signal transmitter 180 provided on the first supporting assembly 10 to transmit a signal, and controlling the signal receiver 181 provided on the second supporting assembly 20 to receive the transmitted signal to determine that the supporting assembly 60 rises to the initial height.
[0075] Specifically, the combined use of the signal transmitter 180 and the signal receiver 181 can monitor the rising height of the support assembly 60 in real time and accurately determine whether it has reached the initial height, providing accurate position information for subsequent assembly operations and ensuring the accuracy and consistency of the assembly process.
[0076] In step S43 , when the supporting assembly 60 rises to the initial height, the rotary driving member 110 is controlled to stop driving the supporting assembly 60 to rotate, so that the nut assembly is assembled to the preset position of the handle 210 to form the handle 200 .
[0077] Specifically, based on the rising height information of the supporting assembly 60, the rotating drive component 110 can be accurately controlled to stop rotating, and the nut assembly can be accurately assembled to the preset position of the shank 210, ensuring that the assembly position and connection degree of each shank 200 remain highly consistent, thereby improving the overall consistency and quality stability of the product.
[0078] Thus, by executing the above steps, the rotary drive member 110 drives the rotary member 70 to rotate, thereby achieving the rotation of the knife handle 210. At the same time, the first elastic member 90 elastically resets and pushes the support assembly 60 to drive the knife handle 210 upward, so that the knife handle 210 can be quickly and accurately threadedly connected to the nut assembly. At the same time, the signal transmitter 180 and the signal receiver 181 cooperate with each other to achieve real-time monitoring of the rising height of the support assembly 60. When the support assembly 60 rises to the initial height, the rotary drive member 110 is promptly controlled to stop driving, thereby accurately assembling the nut assembly to the preset position of the knife handle 210, achieving precise assembly of the knife handle 200 and improving assembly accuracy.
