Description

Technical Field

[0001] The invention relates to a feeding device, in particular to a clip feeding device. Background Art

[0002] Clips are commonly used tools in daily life, used to clamp objects. Clips are generally assembled from two clips, a torsion spring and a latch. Currently, clips with relatively regular shapes are generally assembled by clip assembly machines.

[0003] The Chinese patent No. 201711482682.4 discloses an automatic clip assembly machine, which can assemble clips with relatively regular clip shapes. When the assembly machine is working, the clip feeding device feeds two clips into the clip seat one by one for assembly and positioning, and then installs the torsion spring and the latch into the assembled clip.

[0004] When the clip feeding device feeds materials, the clips are fed into the longitudinally arranged guide slide one by one under the action of the vibrating plate, and the clips are stacked up and down in the longitudinal guide slide, and the outlet at the lower end of the guide slide is aligned with the feed opening on the feed seat. The clips at the lowest end of the guide slide can enter the feed seat and are fed out one by one from the opening at the front end of the feed seat under the action of the push rod in the feed seat.

[0005] This feeding device is suitable for pushing clips with relatively flat upper and lower end surfaces, but is not suitable for pushing clips with uneven upper and lower end surfaces. Figure 1 The clip of the small claw clip shown in the figure comprises a sheet body 27, two pivot ears 28 and a limit column 29 are arranged on the inner side of the sheet body 27, and a plurality of clamping claws 30 are arranged at the front end of the sheet body 27. The upper and lower end surfaces of this clip are not flat, and the arrangement of the clips is unstable when stacked longitudinally. It is easy for the two adjacent clips to be misaligned and stuck. Figure 2 As shown, the lower end protrusion 32 of the upper clip is in front of the upper end protrusion 31 of the next clip, so that when the bottom clip is pushed forward, the bottom clip and the clip stacked on it will be stuck, affecting the smoothness of the clip push. And due to the existence of the sticking, the clip is easy to swing when it is pushed out, so that the overall direction of the clip changes, causing the front end of the clip to easily collide with the side wall of the pusher, causing the jaw to break, affecting the push accuracy and failure rate. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a clip feeding device that can accurately feed the clip. The clip moves smoothly during the pushing process, the feeding efficiency is high, and it is not easy to get stuck or damaged, which can effectively reduce the occurrence of faults.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a clip feeding device, including a discharge seat, a horizontal discharge groove is arranged in the discharge seat, and also includes a driving device for driving the clip to move along the discharge groove, and a gear rod 1 and a gear rod 2 that penetrate into the discharge groove are arranged on the outer side of the discharge seat, and also includes a push block, which is installed on the pushing device. Under the action of the pushing device, the push block can move up and down and be pushed horizontally along the direction of the discharge groove. An elastic positioning device is arranged at the front end of the discharge groove to block the clip, and the discharge groove between the elastic positioning device and the gear rod 1 is a pushing section.

[0008] Through the above technical solution, the rear end of the discharge trough can be connected to a feeding device such as a vibration plate so that the clips can be sent into the discharge trough one by one and arranged horizontally in the discharge trough. Then the clip moves to the front end of the discharge trough under the action of the driving device. Gear rod one and gear rod two extend into the discharge trough, and gear rod one and gear rod two can extend into or withdraw from the discharge trough under the action of the power device. The space between gear rod one and gear rod two can only place one clip. Gear rod one and gear rod two can cooperate to separate the clips so that the clips are sent to the front end of the discharge trough one by one. Since the overall length of the clip is small and the adjacent clips are closely attached, it is impossible to accurately separate the clips one by one without setting two gear rods. If the clips are not separated one by one, the push block cannot accurately extend to the rear of the clip, thereby pushing the clip to move to the front end of the discharge trough. The elastic positioning device can position the single clip moved to the front end of the discharge chute so that it is in front of the initial position of the push block, and then the push block moves downward to push the clip to overcome the obstruction of the elastic positioning device and be sent into the clamp seat.

[0009] The first and second gear bars can be arranged on both sides of the discharge trough, respectively, or on the same side of the discharge trough. In addition, the first and second gear bars can also be arranged below or above the discharge seat, and extend into the discharge trough from below or above the discharge seat. When the first and second gear bars separate the clips, the first gear bar close to the front end of the discharge trough first extends into the discharge trough to block the clip behind the first gear bar, and then the second gear bar extends into the discharge trough to block the clip behind the first gear bar. After the second gear bar extends into the discharge trough or at the same time, the first gear bar retracts and exits the discharge trough, so that the clip between the first and second gear bars can continue to move forward to the front end of the discharge trough and be blocked by the elastic positioning device.

[0010] The elastic positioning device is elastic, and its end protrudes out of the discharge groove to block and position the clip. When the push block pushes the clip forward, the clip can push the elastic positioning device out of the discharge groove, so that the clip can continue to move forward. After the clip passes, the elastic positioning device automatically resets and protrudes out of the discharge groove again to block the clip.

[0011] It should be noted that this feeding device is not only used for feeding small claw clamps, but can also be used for feeding objects or clamps that are similar in shape to the small claw clamps and whose upper and lower end surfaces are not flat.

[0012] Preferably, the driving device is a linear feeder and / or a nozzle connected to compressed gas.

[0013] Through the above technical solution, the driving device can be arranged below the discharge seat along the direction of the discharge trough, so as to drive the clip to move along the discharge trough. At the same time, a nozzle connected to compressed gas can also be used. The nozzle can be arranged above the discharge trough in multiple ways. The nozzles are arranged along the direction of the discharge trough, and the front end of the nozzle faces the clip and sprays gas, so as to push the clip to move along the discharge trough. Of course, the linear feeder and the nozzle can be used at the same time to improve the driving effect. The nozzle and the linear feeder can also promote each other when used together. When the nozzle is used alone to blow the clip, since the nozzle always applies thrust to the clip, when the clip at the front end of the discharge trough is blocked by the second gear rod, the nozzle above the discharge trough will continue to apply thrust to the clip, so that the two adjacent clips are pressed tightly and the thrust is always transmitted to the clip that contacts the second gear rod. The clip that contacts the second gear rod and the clip behind it will be subjected to a large thrust, which is easy to deform and get stuck in the discharge trough, thereby affecting the transmission of the clip. When the linear feeder is added, it will vibrate during operation, causing the clip to vibrate as well, which will cause the clip to scatter and prevent it from fitting tightly together, thus preventing the clip from getting stuck in the discharge trough. When the linear feeder is used alone, the clip is in a vibrating state, and the position changes greatly, making it impossible to accurately position it. The nozzle applies pressure to the clip to reduce the vibration amplitude of the clip and move the clip along one side of the discharge trough.

[0014] Preferably, the first gear lever and the second gear lever are connected to the transmission device, the transmission device includes a telescopic part and a fixed seat, a rocker arm is swingably arranged on the fixed seat, the first gear lever and the second gear lever are respectively connected to one end of the rocker arm, and a telescopic part for driving the rocker arm to swing is arranged on one side of the rocker arm.

[0015] Through the above technical solution, when the swing arm swings, the first and second gear rods can move in opposite directions at the same time, and when the first gear rod is inserted into the discharge trough, the second gear rod exits the discharge trough, so that the two can move synchronously. At the same time, only one telescopic member is required, which makes the overall structure simpler, reduces costs, and facilitates processing.

[0016] Preferably, the telescopic member is a driving cylinder, which drives the rocker arm to swing forward, and a reset member for driving the rocker arm to swing reversely is also provided between the rocker arm and the discharge seat.

[0017] Through the above technical solution, the driving cylinder does not need to be connected to the swing rod, but only needs to be arranged on the outside of one end of the swing rod, thereby simplifying the overall structure. When the swing rod needs to be pushed to rotate in the forward direction, the end of the driving cylinder extends to push the swing rod to swing. When the driving cylinder retracts, the reset member pushes the swing rod to swing in the reverse direction to reset. The driving cylinder and the reset member can be respectively arranged on both sides of the same end of the swing rod, or can be arranged diagonally, that is, arranged on both sides of different ends of the swing rod. The reset member can be made of a spring or a tension spring or other elastic materials.

[0018] Preferably, the upper end surface of the discharge seat on the left side of the discharge trough is upper end surface one, and the upper end surface of the discharge seat on the right side of the discharge trough is upper end surface two. Upper end surface one is higher than upper end surface two, and a limiting plate is installed on upper end surface two, and the side edge of the limiting plate extends to the top of the discharge trough; or upper end surface two is higher than upper end surface one, and a limiting plate is installed on upper end surface one, and the side edge of the limiting plate extends to the top of the discharge trough.

[0019] Through the above technical solution, the clip can be better limited when conveying in the discharge chute. The portion of the limit plate extending above the discharge chute can be inserted between the two pivot ears of the clip, so that the inner surface of the pivot ear and the upper and lower surfaces of the limit plate are in conflict, thereby achieving better restriction. Since the clip is composed of two clips, when the left clip is installed, the limit plate is installed on the upper end surface 2, and when the right clip is installed, the limit plate is installed on the upper end surface 1.

[0020] Preferably, the nozzle of the nozzle pipe is inclined toward the side of the discharge groove on the higher side of the upper end of the discharge seat.

[0021] Through the above technical solution, the outer surface of the clamp can always be in contact with the side of the discharge groove on the higher side of the discharge seat, so that the clamp can obtain a better positioning effect during the movement.

[0022] Preferably, the front end of the push block is provided with a protruding tooth for being inserted between two pivot ears.

[0023] Through the above technical solution, the setting of the convex teeth further ensures the stability of the clip during the pushing process and ensures the position accuracy of the clip during pushing. At the same time, the setting of the convex teeth can increase the contact points between the clip and the clip, so that the clip is more evenly stressed during the pushing process and is not easily damaged.

[0024] Preferably, a transition seat is arranged at the front end of the discharge seat, the discharge groove and the limit plate extend into the transition seat, and the elastic positioning device is arranged in the transition seat.

[0025] Through the above technical solution, the elastic positioning device is arranged in the transition seat, and the clip will move to the transition seat after passing the gear rod. The transition seat and the discharge seat are separated and arranged at a distance. The discharge seat and the transition seat are not directly attached, which can prevent the vibration generated by the linear feeder when working from being transmitted to the transition seat through the discharge seat, and prevent the transition seat from vibrating to a certain extent, so as to prevent the vibration of the clip placed on the transition seat from affecting the convex teeth to be inserted between the two pivot ears of the clip.

[0026] Preferably, the pushing device includes a cylinder 1 arranged along the direction of the discharge chute and a cylinder 2 arranged perpendicular to the direction of the discharge chute, and cylinder 1 is fixed to the end of cylinder 2 or cylinder 2 is fixed to the end of cylinder 1.

[0027] Through the above technical solution, the two cylinders are arranged in this way to more conveniently realize the up and down movement of the push block and the reciprocating movement along the direction of the discharge chute.

[0028] Preferably, it also includes a guide sleeve and a guide slider, the guide block is slidably arranged in the guide sleeve, cylinder one is fixedly connected to the rear end of the guide sleeve, the piston rod of cylinder one is connected to the rear end of the guide slider, cylinder two is fixed to the front end of the guide slider, a guide block is fixed at the lower end of cylinder two, and the push block is slidably arranged in the guide block.

[0029] Through the above technical solution, it can be ensured that the push block can move up and down along the direction perpendicular to the discharge chute, and at the same time the push block can move forward and backward along the direction of the discharge chute.

[0030] Preferably, the elastic positioning device includes a positioning member and an elastic member fixed in the transition seat, one end of the positioning member extends into the discharge groove, the elastic member abuts against the other side of the positioning member, and the end of the positioning member is an inclined surface or an arc surface.

[0031] Through the above technical solution, the elastic member generally uses a spring, a mounting hole is opened in the transition seat, the positioning member and the spring are placed in the mounting hole, the end of the positioning member protrudes from the mounting hole toward one side opening of the discharge chute, and the other side of the mounting hole is blocked by a baffle or screws.

[0032] Compared with the prior art, the invention has the following beneficial effects: by adopting a transverse arrangement, the interference problem caused by the longitudinal arrangement of the clips is avoided, so that the clips are pushed more smoothly and the clips are prevented from being damaged during the pushing process. By synchronously moving the first and second levers in opposite directions, the clips can be accurately separated, so that the clips can be sent into the pushing section one by one, and then pushed by the pushing block.

DETAILED DESCRIPTION

[0051] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0052] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0053] like Figure 4 As shown, a small claw clamping piece feeding device comprises a discharge seat 1, and a horizontal discharge trough 2 is provided in the discharge seat 1. The rear end of the discharge trough 2 can be connected to a vibration plate, and the clamping pieces 43 of the small claw clamp are placed in the vibration plate, and then are arranged in a row and fed into the discharge trough 2 under the action of the vibration plate. A fixed seat 13 is installed on the outer side of the front end of the discharge seat 1, and a swing rod 14 is rotatably connected to the fixed seat 13, and the rotation center of the swing rod 14 is located in the middle of the swing rod 14. The two ends of the swing rod 14 are respectively located on both sides of the fixed seat 13, and the two ends of the swing rod 14 are respectively connected to the gear rod 1 3 and the gear rod 2 4. One end of the swing rod 14 is hinged to the end of the gear rod 1 3, and the other end of the swing rod 14 is hinged to the end of the gear rod 2 4.

[0054] The discharge seat 1 is provided with a chute 1 34 and a chute 2 35 which are perpendicular to the discharge chute 2. The chute 1 34 and the chute 2 35 are connected to the discharge chute 2. The gear lever 1 3 is slidably arranged in the chute 1 34, and the gear lever 2 4 is slidably arranged in the chute 2 35. When the swing arm 14 swings, the gear lever 1 3 is driven to slide along the chute 1 34, so that the left end of the gear lever 1 3 can be extended into and withdrawn from the discharge chute 2. Correspondingly, when the swing arm 14 swings to drive the left end of the gear lever 1 3 to extend into the discharge chute 2, it will also drive the left end of the gear lever 2 4 to withdraw from the discharge chute 2.

[0055] A telescopic member 15 for driving the swing rod 14 to swing is provided on one side of the swing rod 14. The telescopic member 15 is a driving cylinder, and the end of the driving cylinder is located outside the rear end of the swing. When the driving cylinder is extended, the piston rod of the driving cylinder pushes the end of the swing rod 14 on this side to swing toward the discharge seat 1, so that the gear bar 13 exits the discharge trough 2 and the swing rod 142 extends into the discharge trough 2. A reset member 16 for driving the swing rod 14 to rotate in the opposite direction is also provided between the swing rod 14 and the discharge seat 1. The reset member 16 uses a tension spring, one end of which is fixed to the lower surface of the discharge seat 1 by screws, and the other end is fixed to the lower surface of the front end of the swing rod 14 by screws. The tension spring and the driving cylinder act on the two ends of the swing rod 14 respectively. When the piston rod of the driving cylinder is retracted, the tension spring drives the swing rod 14 to rotate in the opposite direction, so that the gear bar 13 is inserted into the discharge trough 2 and the gear bar 24 exits the discharge trough 2.

[0056] A pushing device 6 is provided above the discharge chute 2. The pushing device 6 is fixed on the frame of the clamp assembly machine as a whole through a bracket 35. The pushing device 6 includes a cylinder 19 provided along the direction of the discharge chute 2 and a cylinder 20 provided perpendicular to the discharge chute 2. A guide sleeve 21 is fixed to the front end of the cylinder 19, and the side of the guide sleeve 21 is fixed to the bracket 35. A guide slider 22 is slidably provided in the guide sleeve 21, and the guide sleeve 21 limits the sliding direction of the guide slider 22 so that it slides along the direction of the discharge chute 2. The piston rod of the cylinder 19 is fixedly connected to the rear end of the guide slider 22 by a thread, thereby driving the sliding of the guide slider 22. The cylinder 20 is fixed to the front end of the guide slider 22, and the piston rod of the cylinder 20 faces the discharge chute 2. A guide block 23 is installed at the lower end of the second cylinder 20 , a guide groove 36 is opened in the guide block 23 along the direction of the discharge groove 2 , a push block 7 is installed in the guide groove 36 , and the push block 7 is fixed to the piston rod of the second cylinder 20 .

[0057] The front end of the push block 7 is provided with a protruding tooth 18 for being inserted between the two pivot ears 28. Fig.12 As shown, when pushing the clip 43, the protruding tooth 18 is inserted between the two pivoting ears 28 of the clip 43 to further limit the position of the clip 43 and ensure that the position of the clip 43 does not deviate significantly during the pushing process. The left side of the protruding tooth 18 abuts against the inner side of the sheet body 27 of the clip 43, thereby limiting the distance between the left side of the discharge trough 2 and the left side of the protruding tooth 18, and limiting the swing of the sheet body 27 of the clip 43. The front end of the protruding tooth 18 can abut against the limiting column 29 of the clip 43, thereby transmitting thrust and pushing the clip 43 to move.

[0058] The clip feeding device also includes a driving device 10 for driving the clip 43 to move along the discharge trough 2. The driving device 10 includes a linear feeder 11 arranged below the discharge seat 1, and the linear feeder 11 drives the clip 43 to move forward along the length direction of the discharge trough 2 by vibration. At the same time, a nozzle 12 is also arranged on the upper side of the discharge seat 1, and the rear end of the nozzle 12 is connected to the high-pressure gas storage tank, and the nozzle at the front end of the nozzle 12 is inclined toward the clip 43. When working, the nozzle at the front end of the nozzle 12 sprays high-pressure gas, thereby pushing the clip 43 in the discharge trough 2 to move forward along the length direction of the discharge trough 2. The linear feeder 11 and the nozzle 12 can be used separately or simultaneously.

[0059] An elastic positioning device 8 is provided in the discharge seat 1 in front of the gear lever 1 3 and the gear lever 2 4. The elastic positioning device 8 can block the clip 43 passing through the gear lever 1 3 and the gear lever 2 4, so that the clip 43 stays behind the elastic positioning device 8. The discharge trough 2 between the elastic positioning device 8 and the gear lever 1 3 is a push section 9. The length of the push section 9 is greater than the length of the clip 43 plus the end of the push block 7. The push section 9 is used to place a clip 43 and allow the push block 7 to extend behind the clip 43, so that the push device 6 can smoothly push the clip 43 to move toward the front end of the discharge trough 2.

[0060] like Figure 6 As shown, the upper end surface of the discharge seat 1 on the left side of the discharge trough 2 is the upper end surface 1 41, and the upper end surface of the discharge seat 1 on the right side of the discharge trough 2 is the upper end surface 2 42, and the upper end surface 1 41 is higher than the upper end surface 2. The upper end surface 2 42 on the right side of the discharge trough 2 is installed with a limit plate 17, and the side edge of the limit plate 17 on the left side extends into the upper part of the discharge trough 2. Figure 8 and Fig. 9 As shown, when the clip 43 slides into the discharge trough 2, the two pivot ears 28 of the clip 43 are respectively located on the upper and lower sides of the limit plate 17, and the upper and lower surfaces of the limit plate 17 respectively cooperate with the inner surfaces of the two pivot ears 28 to limit the position of the clip 43. The left side of the limit plate 17 contacts the end of the limit column 29 on the clip 43, limiting the swing of the clip 43 in the discharge trough 2 along the width direction of the discharge trough. The nozzle 12 is arranged above the limit plate 17, and the nozzle at the front end of the nozzle 12 is inclined toward the left side of the discharge trough 2, and the high-pressure gas ejected through the nozzle pushes the clip 43 to move.

[0061] A transition seat 37 is provided at the front end of the discharge seat 1, and the transition seat 37 is separated from the discharge seat 1, and the discharge trough 2 and the limit plate 17 extend to the transition seat 37. The transition seat 37 is separated from the discharge seat 1, which can prevent the vibration generated by the linear feeder 11 from being transmitted to the transition seat 37 when the linear feeder 11 is used to convey the clamping piece 43, causing the transition seat 37 to also generate moving vibration, causing the end of the transition seat 37 to swing, affecting the position accuracy between the transition seat 37 and the clamping seat 38, and affecting the feeding accuracy of the clamping piece 43.

[0062] The elastic positioning device 8 is arranged in the transition seat 37. A mounting hole 39 is provided on one side of the transition seat 37, and the mounting hole 39 is vertical to the discharge trough 2 and connects the discharge trough 2 and the side of the transition seat 37. A positioning member 25 and an elastic member 24 are installed in the mounting hole 39, and the end of the positioning member 25 extends from the mounting hole 39 toward one end of the discharge trough 2, and a cover plate 40 for closing the mounting hole is arranged at the other end of the mounting hole 39. The positioning member 25 can use a steel ball, and the mounting hole 39 is set with a reduced diameter at one end of the discharge trough 2, so that the hole diameter of the right end of the mounting hole 39 is smaller than the ball diameter of the steel ball, so that a part of the right side of the steel ball can protrude from the discharge trough 2, and the steel ball will not fall out of the mounting hole. The surface of the steel ball protruding from the discharge trough 2 is an arc surface 26, so that when the clip 43 conflicts with the steel ball during the pushing process, the steel ball can be pushed into the mounting hole 39, so that the clip 43 can pass through the place smoothly.

[0063] When the device is working, the front end of the transition seat 37 faces the clamp seat 38, and the discharge trough 2 faces the clip installation area in the clamp seat 38. When the clip 43 moves into the discharge seat 1 under the action of the vibration plate, the outer side of the clip 43 contacts the higher left side of the discharge trough 2, and the limit plate 17 is inserted between the two pivot ears 28. At the same time, the side of the limit plate 17 limits the end position of the limit column 29, controls the activity space of the clip 43 during transportation in the discharge trough 2, and positions the clip 43. Under the joint action of the linear feeder 11 below the discharge seat 1 and the nozzle 12 above the discharge seat 1, the clip 43 moves forward in the discharge trough 2. During the movement of the clip 43, the transmission device 5 works to separate the clips 43 one by one, so that the clips 43 can enter the push section 9 one by one.

[0064] When the clip 43 is separated, Fig.16 As shown, first, the swing rod 14 is in the initial state, at which time the front end of the swing rod 14 contacts the right side of the discharge seat 1 under the action of the tension spring, at which time the gear lever 1 3 is inserted into the discharge trough 2, and the gear lever 2 4 is pulled out of the discharge trough 2. A clip 43 at the front end of the discharge trough 2 can enter the discharge trough 2 between the gear lever 1 3 and the gear lever 2 4 under the drive of the linear feeder 11 and the nozzle 12. A sensor for sensing the clip 43 can be provided in the discharge trough 2 between the gear lever 1 3 and the gear lever 2 4. The sensor can be a photoelectric switch to detect whether the clip 43 enters the discharge trough 2 between the gear lever 1 3 and the gear lever 2 4. When the clamping piece 43 is detected in the discharge trough 2 between the gear lever 1 3 and the gear lever 2 4, the driving cylinder extends out, contacts the rear end of the swing lever 14 and contacts the rear end of the swing lever 14 with the right side of the discharge seat 1. At this time, the front end of the swing lever 14 rotates counterclockwise, driving the gear lever 1 3 to move to the outside of the discharge trough 2, and the gear lever 2 4 is inserted into the discharge trough 2. Fig.17As shown, at this time, the gear lever 2 4 blocks the clip 43 behind the gear lever 2 4, so that it cannot enter between the gear lever 1 3 and the gear lever 2 4. At the same time, the clip 43 between the gear lever 1 3 and the gear lever 2 4 continues to move forward under the action of the linear feeder 11 and the nozzle 12 until it contacts the elastic positioning device 8 at the front end of the discharge trough 2. Then the piston rod of the driving cylinder retracts, and the swing rod 14 rotates clockwise under the action of the tension spring to restore the initial state. At this time, the gear lever 1 3 is reinserted into the discharge trough 2 to block the clip 43, and the gear lever 2 4 withdraws from the discharge trough 2, so that the clip 43 blocked by the gear lever 2 4 can continue to move forward.

[0065] A sensing device for detecting the clip 43 is arranged behind the elastic positioning device 8. The sensing device can be a photoelectric switch. When the sensing device detects the clip 43, the pushing device 6 above the pushing section 9 works. The piston rod of the second cylinder 20 extends downward, so that the convex tooth 18 at the front end of the push block 7 is directly opposite to the space between the two pivot ears 28 of the clip 43. Then the piston 1 extends forward, so that the convex tooth 18 is inserted between the two pivot ears 28 and drives the clip 43 to overcome the obstruction of the elastic positioning device 8 and continue to move forward until the clip 43 is pushed to the installation space in the clamp seat. Then the piston rod of the first cylinder 19 retracts, so that the clip 43 is left in the clamp seat, and then the piston rod of the second cylinder 20 retracts, so that the push block 7 returns to the initial position. At the same time, the clamp seat 38 with the clip 43 installed moves to the next station, and the clamp seat 38 without the clip 43 installed moves to the front end of the discharge seat 1. Then the driving cylinder drives the swing rod 14 to swing, and the next feeding process begins.

[0066] It should be particularly noted that the embodiment only takes the small claw clamping piece 43 with a relatively complex structure as an example to explain the feeding device of the clamping piece 43, and some corresponding clamping pieces with simpler structures (for example, the upper and lower ends of the clamping piece 43 are flat, the outer side surface of the clamping piece 43 is flat, etc.) or similar structures can also be fed through the feeding device.

[0067] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
