Description

Technical Field

[0001] The present application relates to the technical field of embroidery machine accessory processing equipment, and in particular to an automatic assembly device for lower production points. Background Art

[0002] The lower dead center is a component used in the head of the embroidery machine, also known as the lower dead center. The publication number CN118273015A discloses "a tape embroidery device and a tape embroidery machine". Figure 4 As can be seen in the figure, the lower control point is connected to the needle bar and moves synchronously with the needle bar. The structure of the existing lower control point is as follows Figure 1 As shown, it includes a connecting part, which has a connecting hole, through which the needle bar can pass, and the connecting hole is connected to a cutout. The connection between the needle bar and the lower control point is similar to a clamp connection structure. After the needle bar passes through the connecting hole, a fastener is needed to reduce the opening of the cutout and then lock the needle bar to achieve a fixed connection effect.

[0003] The lower control point needs to be locked and sold together with the fasteners when leaving the factory. The existing locking process generally adopts manual assembly, using manual or electric tools to connect the fasteners to the lower control point one by one. This assembly method is not only inefficient but also has high labor costs. Summary of the invention

[0004] In order to improve assembly efficiency and reduce labor costs, the present application provides an automatic assembly device for a lower production point.

[0005] The present application provides a bottom-up automatic assembly device that adopts the following technical solution:

[0006] A bottom-up automatic assembly device, comprising:

[0007] frame;

[0008] The lower control point feeding mechanism comprises a vibrating plate and a connected lower control point conveying channel;

[0009] A fastener feeding mechanism, mounted on the frame, comprising a material storage and loading mechanism and a material transfer mechanism connected to the material storage and loading mechanism; and

[0010] An assembly mechanism, installed on the mechanism, includes a pushing assembly connected to the conveying channel of the lower control point, a locking assembly connected to the material transfer mechanism, and a limiting assembly for positioning the lower control point;

[0011] Among them, the material storage and loading mechanism includes a storage box containing fasteners and a fastener conveying channel accommodated in the storage box, one end of the fastener conveying channel is connected to the material moving mechanism, and the material moving mechanism includes a conveying hose, which is used to convey the fasteners output by the fastener conveying channel to the locking assembly.

[0012] By adopting the above technical scheme, the lower control points are transported one by one from the lower control point vibration plate to the pushing assembly through the lower control point conveying channel, the fasteners are contained in the storage box and transported to the material transfer mechanism by the fastener conveying channel and finally to the conveying hose locking assembly, the lower control points positioned at the limit assembly are connected through the locking assembly, and the manual locking operation is completely replaced in the whole process to realize fully automatic assembly, improve assembly efficiency and reduce labor costs.

[0013] Preferably, the material moving mechanism comprises:

[0014] The material transfer seat has a material transfer channel and an air intake channel connected thereto, and the delivery hose is connected to one end of the material transfer channel;

[0015] A material dividing and blocking assembly is disposed on the material transfer seat and has a first position for receiving fasteners output from the fastener conveying channel and a second position for conveying the fasteners into the material transfer channel; and

[0016] A pneumatic source is connected to the air inlet passage.

[0017] By adopting the above technical solution, when the fasteners are conveyed to the material transfer assembly, the material dividing and stopping assembly realizes the functions of material transfer and material stopping. When material transfer is required, the material dividing and stopping assembly is placed in the second position and is blown into the air inlet channel by the pneumatic source, and the fasteners placed in the material transfer channel are blown into the conveying hose and finally input into the locking assembly, which can realize single conveyance of the fasteners and improve assembly accuracy.

[0018] Preferably, the material dividing and stopping assembly includes a first driving member and a material dividing and stopping seat connected to the first driving member, the material dividing and stopping seat is provided with a receiving interface, and the material dividing and stopping seat is driven by the first driving member to move between a first position and a second position; when the material dividing and stopping assembly is in the first position, the receiving interface is connected to the conveying end of the fastener conveying channel, and when the material dividing and stopping assembly is in the second position, the receiving interface is connected to the material moving channel and closes the output end connected to the fastener conveying channel.

[0019] By adopting the above technical solution, the material dividing and blocking seat realizes the material dividing and blocking effects on the fasteners during the movement between the first position and the second position driven by the first driving member, so that the fasteners can be fed one by one, thereby improving the accuracy of the assembly process.

[0020] Preferably, the material shifting mechanism further comprises a material baffle plate arranged on the material shifting seat, the material baffle plate is placed above the material dividing and baffle seat and a portion of the material baffle plate is placed on one side of the fastener conveying channel.

[0021] By adopting the above technical scheme, when the fasteners are transported from the material storage and loading mechanism to the material transfer mechanism, the material baffle plate can, on the one hand, be placed on one side of the fastener conveying channel to limit the fasteners during conveying and reduce the possibility of them falling off from the fastener conveying channel; on the other hand, the material baffle plate is placed above the material dividing and material baffle seat. When it moves from the first position to the second position on the material dividing and material baffle seat, the material baffle plate can close one end of the material transfer channel. When the pneumatic source blows into the material transfer channel, it can prevent the fasteners from detaching from the side connected to the conveying hose, thereby better improving the stability and accuracy of fastener delivery.

[0022] Preferably, the material storage and feeding mechanism comprises:

[0023] A loading cylinder is placed in the storage box, and the loading cylinder has a loading cavity with one side open;

[0024] A plurality of feeding pieces are evenly distributed in the feeding cavity in a circumferential direction, and a storage groove communicating with the feeding cavity is formed between two adjacent feeding pieces; and

[0025] A second driving member is connected to the loading barrel and is used to drive the loading barrel to rotate in the storage box;

[0026] One end of the fastener conveying channel extends into the loading chamber, and when the loading barrel rotates, the fasteners placed in the storage groove can be separated from the storage groove and fall into the fastener conveying channel.

[0027] By adopting the above technical solution, the fasteners in the storage box are loaded by the loading barrel and placed in the storage tank. When the loading barrel rotates to a certain angle, the fasteners placed in the storage tank are separated from the storage tank under the action of gravity and fall into the fastener conveying channel to complete the loading action. Since the storage tank can accommodate a certain amount of fasteners, the fasteners that fall into the fastener conveying channel during the loading process are also a certain amount, which greatly improves the loading and conveying efficiency.

[0028] Preferably, the material storage and feeding mechanism further comprises:

[0029] A guide cylinder connected to the storage box;

[0030] A shovel barrel is placed in the guide barrel and can move toward or away from one side of the storage box along the axial direction of the guide barrel; and

[0031] A rotating cylinder, rotatably connected to the guide cylinder;

[0032] The shoveling barrel partially extends into the rotating barrel, and the loading barrel is rotatably connected to the shoveling barrel. When the rotating barrel rotates relative to the guide barrel, the shoveling barrel is displaced toward or away from one side of the storage box.

[0033] By adopting the above technical solution, the rotation of the rotating drum can drive the shoveling barrel to move away from or close to one side of the storage box to realize the active shoveling action of the fasteners in the storage box. The guide barrel guides the axial displacement of the shoveling material. At the same time, the setting of the guide barrel can reduce the possibility of fasteners entering the connection of the shoveling barrel or detaching from the storage box. Secondly, when there are not many fasteners left in the storage box, the loading amount is reduced synchronously during the rotation of the loading barrel. The axial sliding of the shoveling barrel can actively move the fasteners into the loading barrel, ensuring the amount of fasteners loaded at one time and improving the continuous working cycle of the entire assembly.

[0034] Preferably, the shoveling barrel is provided with a first guide wheel at the outer wall, and the rotating barrel is provided with a track groove at the inner wall, and the first guide wheel is rollingly connected in the track groove; wherein, the track groove comprises a shoveling stable section, a descending section, a loading stable section and an ascending section which are connected end to end in sequence.

[0035] By adopting the above technical solution, the rolling of the first guide wheel in the track groove is used to realize the axial sliding of the shoveling barrel relative to the guide barrel. The track groove can be designed according to the time period and movement speed of each shoveling and loading, so as to realize the shoveling and loading actions more flexibly. Secondly, the track groove includes four connected sections, which respectively realize the pause of shoveling and loading and the axial reciprocating movement of the shoveling barrel. The special setting of the shoveling stable section and the loading stable section makes the shoveling barrel remain prohibited for a period of time after shoveling to overcome the detachment of the fasteners on the shovel due to inertial action, thereby increasing the amount of shoveling at one time. The setting of the loading stable section gives the loading barrel enough time to rotate and load after the shoveling comes back, which greatly improves the stability of the entire loading.

[0036] Preferably, the material storage and feeding mechanism further includes a locking assembly, and the locking assembly includes:

[0037] A fixed arm connected to the outer wall of the guide cylinder;

[0038] A movable arm, one end of which is rotatably connected to one end of the fixed arm;

[0039] an elastic member connecting the movable arm and the fixed arm; and

[0040] A second guide wheel is arranged on the movable arm and is driven by an elastic member to always contact the outer wall of the guide cylinder;

[0041] In which, the outer wall of the rotating drum has a cam track for the second guide wheel to roll, and the cam track includes a first recessed section, a second recessed section and a raised section connecting the first recessed section and the second recessed section which are connected end to end in sequence; the guide drum is provided with a limiting groove at the outer wall, and the shoveling drum is provided with a first locking groove and a second locking groove at intervals at the outer wall; when the first guide wheel is placed in the shoveling stable section, the second guide wheel is placed in the first recessed section, and the movable arm is clamped in the limiting groove and the first locking groove; when the first guide wheel is placed in the feeding stable section, the second guide wheel is placed in the second recessed section, and the movable arm is clamped in the limiting groove and the first locking groove; when the first guide wheel is placed in the ascending section or the descending section, the second guide wheel is placed in the raised section, and the movable arm is disengaged from the limiting groove.

[0042] By adopting the above technical solution, after the shoveling barrel performs the shoveling action toward one side of the material storage box, the locking component limits the axial displacement of the shoveling barrel to reduce the movement of the shoveling barrel. Specifically, when the shoveling barrel is in the stable shoveling section, the second guide wheel on the movable arm is placed in the first recessed section, and under the action of the elastic member, it moves toward the outer wall of the guide barrel around the rotation point of the movable arm and is simultaneously snapped into the limit groove and the first locking groove of the guide barrel and the shoveling barrel to limit the axial movement of the shoveling barrel, thereby better ensuring the temporary locking after shoveling. Similarly, when the shoveling barrel is placed in the stable loading section after shoveling the material, the second guide wheel is placed in the second recessed section, and is synchronously snapped into the limit groove and the second locking groove to lock the shoveling barrel, so that the rotation of the loading barrel can more fully load the fasteners after the shoveling returns, thereby better ensuring the loading amount of the fasteners and improving the continuity of the assembly process.

[0043] Preferably, the material storage box comprises an inclined section for material discharge and a straight section, wherein the inclined section for material discharge is inclined toward one side of the material loading barrel, and one end of the straight section extends toward one side of the material shoveling barrel.

[0044] By adopting the above technical solution, the fasteners placed in the material storage box can be displaced toward the side of the loading barrel through the unloading inclined section driven by gravity, so that a sufficient amount of them can be placed in the loading barrel before shoveling. As the remaining amount of fasteners after loading gradually decreases, the axial shoveling action of the shoveling barrel is combined to ensure that a sufficient amount of fasteners is provided to the upper barrel, and the setting of the straight section provides the shoveling barrel with a certain stroke displacement to ensure the normal shoveling action.

[0045] Preferably, the pushing assembly includes a third driving member and a first pushing block connected to the third driving member, and the pushing block is driven by the third driving member to move closer to or away from one side of the limit assembly; the limit assembly includes a limit seat, a fourth driving member, a second pushing block connected to the fourth driving member, a fifth driving member and a limit block connected to the fifth driving member, the limit seat is provided with a positioning groove, the second pushing block is driven by the fourth driving member to move closer to or away from one side of the positioning groove, the limit block is driven by the fifth driving member to move closer to or away from one side of the positioning groove, and the limit block is provided with a limiting opening that engages with the lower control point; the locking assembly includes a base, an electric screwdriver slidably connected to the base, and a material guide seat connected to the base, the material guide seat is provided with a connected material guide channel and a locking channel, the conveying hose is connected to the material guide channel, the electric screwdriver can extend into the locking channel, and the locking channel is above the positioning groove.

[0046] By adopting the above technical solution, after the lower control point is transported to the pushing component by the lower control point conveying channel, it is transported to one side of the limit seat by the first pushing block, and then the second pushing block pushes the lower control point into the positioning groove. At this time, the synchronous limit block moves in advance toward one side of the positioning groove, and the lower control point is limited in the limiting opening of the positioning groove and the limit block. The fastener is transported to the locking channel of the locking component by the conveying hose, and the electric screwdriver pushes the fastener toward the connecting hole of the lower control point for locking. The entire assembly process has good continuity and accuracy during the assembly process.

[0047] In summary, the present application includes at least one of the following beneficial technical effects:

[0048] 1. The automatic conveying of the lower control point and the fasteners is integrated into the assembly mechanism to complete the automatic operation of the lower control point assembly and locking, which greatly improves the assembly efficiency and reduces the labor cost at the same time;

[0049] 2. By dividing the feeding action of fasteners into two steps: material storage and material transfer, combined with the setting of material dividing and blocking components during the material transfer process, stable fastener loading and one-by-one feeding operations are achieved, which improves the continuity and stability of the subsequent assembly process;

[0050] 3. The active shoveling and feeding action of the fasteners in the storage box is realized by setting the shoveling barrel and realizing axial sliding, which better guarantees the feeding amount of the disposable fasteners during the feeding process; at the same time, the axial sliding of the shoveling barrel maintains a pause period during the shoveling and feeding process to ensure the stability of the shoveling and feeding process;

[0051] 4. By setting a locking component and combining the axial sliding action of the shoveling barrel, linkage locking is achieved during the shoveling and feeding process, further ensuring the stability of the two process actions of shoveling and feeding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0069] The present application is further described in detail below in conjunction with the accompanying drawings.

[0070] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of this application. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0072] Figure 1 The assembly part structure for a lower control point automatic assembly device in an embodiment of the present application is shown, which includes a lower control point 10 and a fastener 20. The lower control point 10 includes an integrated connecting portion 101 and an extension portion 104. The lateral length of the connecting portion 101 is greater than the lateral length of the extension portion 104, so that a step section is formed between the two. The connecting portion 101 has an axially opened connecting hole 102 and a radially opened pre-tightening hole 105. The connecting hole 102 is for the subsequent needle rod to pass through. The pre-tightening hole 105 is connected to the fastener 20. The pre-tightening hole 105 is also connected to a cutout 103. After the fastener 20 is passed through and connected, the opening of the cutout 103 will be reduced to limit the aperture of the connecting hole 102. In this embodiment, the fastener 20 includes an end 201 and a connected fastening portion 202. The diameter of the end 201 is greater than the diameter of the fastening portion 202, so that the two also form a step section. The assembly device disclosed in this embodiment is used to automatically lock the fastener 20 with the pre-tightening hole 105 of the lower control point 10.

[0073] See also Figure 2 The automatic assembly device for lower control points includes a frame 1, a lower control point feeding mechanism 2, a fastener feeding mechanism 3, an assembly mechanism 4 and a collecting assembly 5. The lower control point feeding mechanism 2 is located at one side of the frame 1 and includes a vibration plate 21 and a connected lower control point conveying channel 22. A plurality of lower control point 10 parts are gradually input into the lower control point conveying channel 22 from the vibration plate 21. One end of the lower control point conveying channel 22 is connected to the assembly mechanism 4 and the lower control point 10 is gradually conveyed to the side of the assembly mechanism 4 by a straight vibrator.

[0074] Combination Figure 3 The fastener feeding mechanism 3 includes a material storage and loading mechanism 32 installed on the frame 1 and a material transfer mechanism 31 connected to the material storage and loading mechanism 32. The material storage and loading mechanism 32 is used to store the fasteners 20 and gradually transfer the fasteners 20 to the material transfer mechanism 31. The material transfer mechanism 31 is used to gradually transfer the fasteners 20 transferred to the assembly mechanism 4 and assemble and connect with the lower assembly point 10 transferred to the assembly mechanism 4.

[0075] The material storage and loading mechanism 32 includes a fastener conveying channel 321 extending at one end to the material moving mechanism 31. The material moving mechanism 31 includes a material moving seat 311 connected to the fastener conveying channel 321. A material dividing and blocking assembly is installed on the material moving seat 311. The material dividing and blocking assembly is used to receive the fastener 20 input from the fastener conveying channel 321 and block the input of the next fastener 20. The specific material blocking assembly includes a first driving member 312 and a connected material dividing and blocking seat 313. The material dividing and blocking seat 313 has a first position for receiving the fastener 20 input to the material moving mechanism 31 and a second position for outputting the fastener 20 to the assembly mechanism 4.

[0076] like Figure 3 As shown, the material dividing and stopping seat 313 is in the first position, and includes a receiving interface 3131 that can be connected to the fastener conveying channel 321. When the material dividing and stopping seat 313 is driven to move by the first driving member 312, the receiving interface 3131 and the output end of the fastener conveying channel 321 are staggered and connected to block the input of the fastener 20 to the material moving assembly.

[0077] Combination Figure 4 and Figure 5 A connected material transfer channel 3111 and an air intake channel 3112 are provided in the material transfer seat 311, one end of the material transfer channel 3111 is opened at the end surface of the material transfer seat 311, and the receiving interface 3131 can be connected to the material transfer channel 3111 during the sliding process of the material dividing and blocking seat 313 along the X direction. At this time, the material dividing and blocking seat 313 is in the second position, and the fastener 20 is input into the material transfer channel 3111 from the receiving interface 3131, and the other end of the material transfer channel 3111 is opened on the side wall of the material transfer seat 311. The air inlet channel 3112 is provided with an output port in the vertical direction, which is higher than the output port of the material transfer channel 3111. The air inlet channel 3112 is connected to the air inlet pipe 315, and the air inlet pipe 315 is connected to the pneumatic source 314. The pneumatic source 314 can blow into the air inlet channel 3112 through the air inlet pipe 315, and the airflow will push the fasteners 20 in the material transfer channel 3111 to move toward the side wall opening of the material transfer seat 311. The side wall opening of the material transfer channel 3111 is connected to the conveying hose 316, and the other end of the conveying hose 316 is connected to the assembly mechanism 4, and then combined with the material dividing and blocking assembly, the fasteners 20 are conveyed one by one during the reciprocating movement between the first position and the second position.

[0078] The material moving mechanism 31 also includes a material baffle plate 317 installed on the material moving seat 311. Part of the material baffle plate 317 is placed on one side of the fastener conveying channel 321 to reduce the derailment of the fastener 20 during the input process. At the same time, the material baffle plate 317 is also above the material dividing and material baffle seat 313. A space for the material dividing and material baffle seat 313 to slide is formed between the material baffle plate 317 and the material moving seat 311. When the material dividing and material baffle seat 313 is placed in the second position, the material baffle plate 317 can close the receiving interface 3131, and then during the air supply process of the pneumatic source 314, the fastener 20 will not be output from the upper end opening of the material moving seat 311.

[0079] Shared Reference Figure 6 and Figure 7 The material storage and loading mechanism 32 includes a material storage box 324, a loading barrel 322 placed in the material storage box 324, and a second driving member 33 that drives the loading barrel 322 to rotate in the material storage box 324. The loading barrel 322 includes a loading cavity 3221 opened on one side, and a plurality of loading members 323 are evenly distributed in the circumferential direction of the loading cavity 3221. A storage groove 3231 communicating with the loading cavity 3221 is formed between two adjacent loading members 323. The cross section of the loading member 323 is roughly arc-shaped. After the fastener 20 enters the storage groove 3231, it can reduce the possibility of being separated from the opening of the material storage groove communicating with the loading cavity 3221. When the loading barrel 322 rotates and the opening of the storage groove 3231 gradually faces downward, the fastener 20 will fall from the storage groove 3231 into the loading chamber 3221 under the action of gravity. One end of the fastener conveying channel 321 extends into the loading chamber 3221, thereby receiving the fastener 20 dropped from the storage groove 3231.

[0080] Due to the structural setting of the fastener 20, some fasteners 20 will fall in the wrong direction when falling into the fastener conveying channel 321, resulting in failure to enter the fastener conveying channel 321. Furthermore, a scraper plate 318 is also provided in the material storage and loading mechanism 32. The scraper plate 318 is connected to the transmission shaft 3191 and is placed above the fastener conveying channel 321. One end of the transmission shaft 3191 is hinged to a cylinder 319, and the other end of the cylinder 319 is hinged to the side wall of the storage box 324. The cylinder 319 can drive the transmission shaft 3191 to rotate and drive the scraper plate 318 to swing. The swing of the scraper plate 318 will scrape off the fasteners 20 that fall into the fastener conveying channel 321 in the wrong direction and fall back into the storage box 324.

[0081] Combination Figure 8The material storage and loading mechanism 32 further includes a guide cylinder 325, a shoveling cylinder 326 and a rotating cylinder 327. The guide cylinder 325 is connected to the side wall of the material storage box 324, and the rotating cylinder 327 is connected to the guide cylinder 325 and can rotate relative to each other. At the same time, the rotating cylinder 327 is restricted from rotating circumferentially between the guide cylinder 325 and the rotating cylinder 327. The shoveling cylinder 326 is placed in the guide cylinder 325 and the rotating cylinder 327 and can be axially displaced relative to the two. During the axial sliding process, the shoveling cylinder 326 can extend into the material storage cavity 3241 of the material storage box 324 to realize the active shoveling action of the fastener 20 placed in the material storage cavity 3241.

[0082] The bottom of the storage box 324 is provided with a connected unloading inclined section 3242 and a straight section 3243. The unloading inclined section 3242 is arranged to be inclined downward toward the side of the loading barrel 322, and one end of the straight section 3243 extends to the side of the loading barrel 322. Under normal circumstances, the fastener 20 placed in the storage chamber 3241 can slide along the unloading inclined section 3242 toward the side of the loading barrel 322 under the action of gravity and realize loading. At the same time, since the fastener conveying channel 321 is also connected to the straight vibrator, the vibration of the straight vibrator during operation can also drive the storage box 324 to vibrate to a certain extent to promote the fastener 20 to slide toward the side of the loading barrel 322.

[0083] Combination Fig. 9 The shovel barrel 326 is provided with a first guide wheel 3263 on the outer wall, and the rotating barrel 327 is provided with a track groove 3271 on the inner wall, and the first guide wheel 3263 is rollingly connected in the track groove 3271. The rotating barrel 327 is driven to rotate by the driving motor 329 through the gear transmission, and the shovel barrel 326 is driven to reciprocate along the axial direction of the guide barrel 325 by the rolling of the first guide wheel 3263 in the track groove 3271 during the rotation.

[0084] The track groove 3271 is a closed groove including a shoveling stable section 327a, a descending section 327b, a loading stable section 327c and an ascending section 327d which are connected in sequence. When the first guide wheel 3263 is placed in the shoveling stable section 327a and the loading stable section 327c, the shoveling barrel 326 is in a stationary state, and when the first guide wheel 3263 is placed in the descending section 327b, the shoveling barrel 326 moves away from the material storage chamber 3241, and when the first guide wheel 3263 is placed in the ascending section 327d, the shoveling barrel 326 moves close to the material storage chamber 3241.

[0085] Combination Fig.10The material storage and feeding mechanism 32 further includes a locking assembly 328, which is used to lock the axial movement of the first guide wheel 3263 of the shoveling barrel 326 during the process of being placed in the shoveling stable section 327a and the feeding stable section 327c. The locking assembly 328 includes a fixed arm 3281 fixed to the guide barrel 325, a movable arm 3282 hinged at one end to the fixed arm 3281, and an elastic member 3283 connecting the fixed arm 3281 and the movable arm 3282. Under the action of the elastic member 3283, the movable arm 3282 always has a swinging tendency toward one side of the guide barrel 325.

[0086] Combination Fig.11 The movable arm 3282 is also connected to a second guide wheel 3284, which contacts the outer wall of the rotating drum 327 and always has a tendency to move toward the outer wall of the rotating drum 327 under the action of the elastic member 3283. At the same time, a cam track 3272 is also provided on the outer wall of the rotating drum 327, and the second guide wheel 3284 rolls on the cam track 3272. The cam track 3272 includes a first concave section 327e, a second concave section 327f, and a convex section 327g connecting the first concave section 327e and the second concave section 327f. The thickness of the first concave section 327e and the second concave section 327f is smaller than that of each part of the convex section 327g. The first concave section 327e and the second concave section 327f have the same wall thickness and each part has the same diameter. When the second guide wheel 3284 rolls on the cam track 3272, it can drive the movable arm 3282 to swing away from or close to the fixed arm 3281. When the second guide wheel 3284 rolls on the raised section 327g, the swing amplitude of the movable arm 3282 is greater than when it rolls on the first recessed section 327e and the second recessed section 327f.

[0087] The shovel barrel 326 is provided with a first locking groove 3261 and a second locking groove 3262 at intervals on the outer wall, and the guide barrel 325 is provided with a limiting groove 3251, and a part of the movable arm 3282 is clamped in the limiting groove 3251. When the second guide wheel 3284 is placed on the raised section 327g, the movable arm 3282 swings away from the fixed arm 3281. At this time, the movable arm 3282 cannot be clamped in the first locking groove 3261 and the second locking groove 3262, and when the second guide wheel 3284 is placed on the raised section 327g, the movable arm 3282 swings away from the fixed arm 3281. When 84 is placed in the first recessed section 327e and the second recessed section 327f, the movable arm 3282 leans against the fixed arm 3281 under the action of the elastic member 3283. At this time, when the shovel barrel 326 slides axially to a certain stroke, the limiting groove 3251 is connected with the first locking groove 3261 or the second locking groove 3262, and the movable arm 3282 is simultaneously inserted into the limiting groove 3251 and the first locking groove 3261 or the second locking groove 3262 to realize the locking of the axial movement of the shovel barrel 326.

[0088] Combination Fig.12 and Fig.13 During the rotation of the rotating drum 327, when the shoveling drum 326 slides relative to the guide drum 325 toward the side of the material storage chamber 3241, the first guide wheel 3263 is placed at the upward section 327d. After the shoveling drum 326 slides for a period of time, the first guide wheel 3263 is placed at the shoveling stable section 327a, and the second guide wheel 3284 is placed at the first recessed section 327e. The movable arm 3282 swings toward the side of the fixed arm 3281 and is synchronously snapped into the first locking groove 3261 to shovel the material. The barrel 326 is locked. The locking of the shoveling barrel 326 ensures that the shoveling material into the shoveling barrel 326 has a stabilizing effect on the fasteners 20 due to inertia when the shoveling material is in a stationary state. At the same time, it has a stabilizing effect when the shoveling barrel 326 retracts, reducing the fasteners 20 from escaping from the shoveling barrel 326 due to inertia. In addition, due to the effect of the straight vibrator, the material storage box 324 can allow some fasteners 20 to enter the shoveling barrel 326 in a vibrating state when locked, so as to bring back as many fasteners 20 as possible at one time.

[0089] As the rotating drum 327 continues to rotate, the second guide wheel 3284 rolls from the first recessed section 327e to the raised section 327g, and the movable arm 3282 gradually swings away from the side of the fixed arm 3281 until the movable arm 3282 disengages from the first locking groove 3261. At this time, the first guide wheel 3263 of the shoveling barrel 326 enters the downward section 327b, and the shoveling barrel 326 moves away from the storage chamber 3241, that is, moves toward the side of the loading barrel 322. The shoveling barrel 326 inputs the fasteners 20 brought back into the loading chamber 3221 of the loading barrel 322 to realize active loading action. When the shovel barrel 326 moves a certain distance, the first guide wheel 3263 rolls to the loading stable section 327c, the shovel barrel 326 is in a stationary state, and the second guide wheel 3284 rolls from the raised section 327g to the second recessed section 327f, and the movable arm 3282 swings toward the side of the fixed arm 3281 again, and is inserted into the second locking groove 3262 to lock the shovel barrel 326. At this time, the rotation of the loading barrel 322 can perform the loading action more smoothly without being affected by the sliding of the shovel barrel 326.

[0090] During the sliding process of the shovel barrel 326 in the storage chamber 3241, since the storage box 324 has a straight section 3243 at one end for the shovel barrel 326 to slide normally, combined with the setting of the fastener 20 in the unloading inclined section 3242, the fastener 20 can bring back more fasteners 20 to the upper barrel 322 during the downward process combined with the sliding of the shovel barrel 326.

[0091] Shared Reference Figures 14 to 16The assembly mechanism 4 is used to connect the input lower control point 10 with the fastener 20.

The second pushing block 424 receives the lower control point 10 pushed by the first pushing block 412, and pushes the lower control point 10 toward one side of the limiting seat 421. The limiting seat 421 is provided with a positioning groove 422, and the second pushing block 424 can push the lower control point 10 into the positioning groove 422. The limiting block 426 is provided with a limiting opening 4261, and the limiting opening 4261 can be engaged with the extension portion 104 of the lower control point 10 so that the connecting portion 101 contacts the end 201 of the limiting block 426 to achieve the acceptance of the lower control point 10. The limit seat 421 defines a sliding channel, and the limit block 426 can enter the sliding channel and move under the drive of the fifth driving member 425 and finally slide into the positioning groove 422 . Combined with the abutment of the second pushing block 424 , the lower control point 10 is locked in the positioning groove 422 .

[0093] The locking assembly 43 includes a base 431, an electric screwdriver 432 slidably connected to the base 431, and a material guide seat 433 connected to the base 431. The material guide seat 433 is provided with a material guide channel 4331 and a locking channel 4332, the delivery hose 316 is connected to the material guide channel 4331, the locking channel 4332 is directly opposite to the positioning groove 422, and the electric screwdriver 432 can be inserted into the locking channel 4332 to lock the fastener 20 on the lower control point 10.
