Description

Technical Field

[0001] The invention relates to the technical field of clip assembly machines, and in particular to automatic stationery clip assembly equipment. Background Art

[0002] The clamp is a commonly used clamping tool in daily life. At present, most of the clamps are assembled by a clamp assembly machine. As shown in the Chinese patent No. 201711482682.4, it includes a rotating disk, which is driven to rotate by a divider. A plurality of clamp seats are evenly distributed on the circumference of the rotating disk, and a plurality of workstations are arranged on the frame outside the clamp seat facing the clamp seat, and two clip installation devices, a spring pin installation device, a rivet device and a material removal device are respectively installed on the workstations.

[0003] When the above assembly machine assembles the clip, the clip is placed sideways, and when the clip is fed into the clip seat, the clip is first stacked longitudinally along the clip width direction above the feed port of the feed seat. The clips enter the feed seat one by one under the action of gravity, and are fed into the clip seat along the clip height direction under the action of the push rod in the feed seat for assembly.

[0004] This type of clip assembly machine can only assemble clips whose sides are partially flat and can be stably placed on their side, but cannot assemble clips whose sides are uneven and cannot be stably placed on their side. In real life, the sides of many clips are not flat.

[0005] like Fig. 22 As shown, the clip of the stationery clip includes a pressing portion 91 and a clamping portion 92, a pivoting ear 93 is provided between the pressing portion and the clamping portion, and a pin hole 94 is provided on the pivoting ear 93. The width of the pressing portion 91 is much smaller than the width of the clamping portion 92, resulting in the side of the clip not being a plane, and the clip cannot be stably placed sideways. The above-mentioned clip assembly machine is not suitable for assembling clips whose side of the clip is not a plane. Summary of the invention

[0006] In view of the shortcomings of the prior art, the object of the present invention is to provide an automatic assembly device for stationery clips, which can assemble clips whose sides are not flat and cannot be stably placed on their side.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: an automatic assembly device for stationery clips, comprising a frame, a controller and a rotating disk are arranged on the frame, a clamp seat is installed on the rotating disk, a clip installation device 1, a clip installation device 2, a torsion spring installation device, a pin installation device, a pin pressing device and a material taking device are installed on the frame outside the rotating disk, the clamp seat comprises a seat body, a clip seat 1 and a clip seat 2 are arranged on the seat body, and clip seat 1 and clip seat 2 are both provided with clip placement grooves, the clip placement grooves extend along the width direction of the clip, and two clips are placed The grooves are inclined to both sides of the vertical direction respectively, the clip seat two is located on one side of the clip seat one and can move away from the clip seat one, the clip installation device one and the clip installation device two both include a discharge seat one and a clip driving device, a clip discharge groove is opened in the discharge seat one, an elastic positioning piece is arranged at the front end of the discharge seat one, the end of the elastic positioning piece is inserted into the clip discharge groove to block and position the clip, a clip clamping and pushing device is arranged above the discharge seat one, the clip clamping and pushing device clamps the upper end of the clip and drives the clip to push the elastic positioning piece away from the front end of the clip discharge groove and install it in the clip seat.

[0008] Through the above technical solution, the clip can be pushed, placed and spliced ​​in an upright manner. When the clip is positioned, the lower end of the clamping part and the outer surface of the clip part are used as positioning surfaces to achieve the positioning of the clip. The clip is pushed along its width direction when pushed. A clip seat 1 and a clip seat 2 are provided on the clamp seat, and the clip seat 2 can move laterally relative to the clip seat 1, so that the distance between the clip seat 1 and the clip seat 2 is greater than the sum of the widths of the pivot ears of the two clips. After the two clips are respectively installed in the clip seat 1 and the clip seat 2, the clip seat 2 moves laterally toward the clip seat 1, so that the clips are spliced. When the two clips are spliced, the two clips are spliced ​​laterally, so as to avoid interference between the pivot ears of the two clips in the width direction.

[0009] The clamping and pushing device of the clip can clamp the upper end of the clip and push the clip from the discharge seat into the clamp seat, thereby realizing the installation of the clamp seat.

[0010] Preferably, the pin installation device includes a discharge seat three and a pin driving device, a pin discharge groove is opened in the discharge seat three, a pin material moving mechanism is arranged at the front end of the pin discharge groove, the pin material moving mechanism includes a fixed block, a pin material storage seat is slidably arranged in the fixed block, a pin material storage groove is opened in the pin material storage seat, a pin feeding seat is installed at one end of the fixed block, and also includes an insertion pin, which is inserted into the installation seat from the outside of the fixed block, and the pin placed in the pin material storage groove is pushed out from the front end of the pin feed seat and loaded onto the clamp.

[0011] Through the above technical solution, the setting of the fixed block and the pin storage seat in the fixed block enables the pin installation device and the torsion spring installation device to realize the installation of the torsion spring and the pin at the same station. While realizing the installation of the pin, the interference between the discharge seat 3 for conveying the pin and the discharge seat 2 for conveying the torsion spring can be avoided. The pin installation device is arranged in this way so that the pin can be conveyed along its axial direction, and at the same time, through the movement of the pin storage seat, the pin is moved from the front end of the pin discharge groove to the outside of the pin hole on the pivot ear, and then installed in the pin hole through the pin.

[0012] A pin feed seat is also installed on the fixed block. The specific structure of the pin feed seat can refer to patent number 201711482682.4, named as pin feed seat structure in the clamp automatic assembly machine.

[0013] Preferably, the clip placement groove includes a limiting groove at the lower end of the clamping part, and the lower end of the clamping part of the clip is inserted into the limiting groove at the lower end of the clamping part.

[0014] Through the above technical scheme, the setting of the limiting groove at the lower end of the clamping part can better limit the lower end of the clamping part of the clip, so that the clip can be placed more stably and more accurately in the clip seat, so that when the two clips are spliced ​​together, the pin holes on the two clips can be accurately aligned.

[0015] Preferably, the first clip seat and the second clip seat are provided with mounting cavities, and magnetic components are installed in the mounting cavities.

[0016] Through the above technical solution, most general clips are stamped from iron sheets, and the magnetic parts can adsorb the clips installed in the clip seats, so that the outer surface of the clips can fit tightly with the surface of the clip placement cavity, thereby preventing the clips in clip seat one or clip seat two from changing their installation positions due to vibration and other reasons when the clip seat two moves laterally, thereby affecting the accuracy of the clip assembly.

[0017] Preferably, a reset spring is arranged between the clip seat 2 and the seat body, and the reset spring can drive the clip seat 2 to move in the direction of the clip seat 1. A driving groove is arranged on the clip seat 2, and a cross beam is mounted on the rotating disk. A clip seat driving device is installed on the cross beam. The clip seat driving device includes a driving rod, and a driving inclined surface 1 is arranged on the driving rod. The driving rod is inserted into the driving groove and pushes the clip seat 2 to slide in the direction away from the clip seat 1 through the driving inclined surface 1.

[0018] Through the above technical solution, a reset spring is arranged between the clip seat 2 and the seat body, so that the clip seat 2 always has a tendency to fit toward the clip seat 1. In the absence of external force, the clip seat 2 can stably fit the clip seat 1, so that the two clip placement grooves are combined into a clip assembly cavity.

[0019] The arrangement of the clip seat driving device can drive the second clip seat to move to a side away from the first clip seat, so that the clip installed in the first clip seat will not affect the second clip from being installed in the second clip seat.

[0020] By providing a driving groove on the second clip seat and a driving inclined surface on the driving rod, when the driving rod is inserted into the driving groove on the clip seat, the second clip seat can be driven to move away from the first clip seat more conveniently. When the driving rod is pulled out of the driving groove, the second clip seat moves toward the first clip seat under the action of the reset spring and fits with the first clip seat again.

[0021] Preferably, the torsion spring installation device includes a discharge seat and a torsion spring driving device, a torsion spring discharge groove is provided in the discharge seat, a torsion spring storage seat is provided at the front end of the discharge seat, a torsion spring storage groove is provided in the torsion spring storage seat, the side of the torsion spring storage groove is connected to the torsion spring discharge groove, a feeding groove is provided below the torsion spring storage groove, a pushing rod which can be retractably inserted into the feeding groove is provided above the feeding groove, a longitudinal driving device is provided on the side of the torsion spring storage seat, and the longitudinal driving device drives the lower end of the torsion spring storage seat to longitudinally insert or withdraw the clamping seat.

[0022] Through the above technical solution, the torsion spring can be conveniently loaded from the upper ends of the two assembled clips to between the two clips, thereby realizing the installation of the torsion spring. The torsion springs can be placed one by one in a side-lying manner in the discharge trough, and transported to the torsion spring storage seat at the front end of the discharge trough under the action of the torsion spring driving device. The storage seat is provided with a longitudinally arranged feeding trough, and a push rod is arranged above the feeding trough. The torsion spring enters the storage trough under the action of the push rod. At the same time, the storage seat can be divided into two parts, and the lower end of the storage seat can be movably arranged. When the push rod pushes the torsion spring into the feeding trough and moves downward, the lower end of the storage seat is also inserted between the two assembled clips, so that the inner ring of the torsion spring and the pin hole on the pivot ear are basically in a concentric state. This allows the pin to pass through the clip and the torsion spring smoothly.

[0023] Preferably, the material picking device includes a fixed frame and a material picking drive device, the front end of the material picking drive device is connected to a push rod mounting block, a push rod is mounted on the push rod mounting block, the push rod is located on the back of the clamp seat, and under the action of the material picking drive device, the push rod passes through the clamp seat along the width direction of the clamp and contacts the clamp, thereby withdrawing the assembled clamp from the clamp seat.

[0024] Through the above technical solution, the assembled clamp can be taken out from the clamp seat more conveniently, so that the clamp seat can realize the next cycle.

[0025] Preferably, a divider is installed on the frame, the input shaft of the divider is connected to the power device, and the rotating disk is fixed on the output shaft of the divider.

[0026] Through the above technical solution, the power device is connected to the divider, and when the power device rotates at a constant speed, it drives the divider to rotate intermittently at equal angles. As a result, the rotating disk also rotates intermittently at equal angles, so that the rotating disk can more conveniently coordinate with the working rhythm of each installation device and realize control more conveniently.

[0027] Preferably, it also includes an angle sensor, the rotating shaft of the angle sensor is connected to the input shaft and rotates at the same angle, the angle sensor is connected to the controller, and the controller detects the rotation angle of the input shaft to control one or more actions of the clip installation device 1, the clip installation device 2, the torsion spring installation device, the pin installation device, the pin pressing device, and the material picking device.

[0028] Through the above technical solution, the setting of the angle sensor can detect the rotation angle of the input shaft of the divider, and through the detection of the rotation angle of the input shaft, the action of each component in each installation device is controlled, so that each device can be installed in a preset action sequence and smoothly realize the installation action. The angle sensor can use an encoder.

[0029] Preferably, it also includes a switch member and a positioning portion that cooperate with each other, the switch member is arranged on the outside of the rotating shaft or the input shaft, and the positioning portion rotates circumferentially with the rotating shaft or the input shaft.

[0030] Through the above technical solution, the controller determines the rotation angle of the input shaft of the divider by processing the pulse signal output by the rotation angle sensor. The switch key and the positioning part cooperate with each other to reset the controller, so that the controller is reset once every rotation of the input shaft, thereby avoiding the accumulation of errors between the controller and the rotation angle sensor during long-term operation, resulting in a deviation between the rotation angle of the input shaft detected by the controller and the actual rotation angle of the input shaft, resulting in the inability to accurately coordinate the actions of the rotating disk and the individual installation devices, affecting the smooth operation of the clip assembly machine.

[0031] Preferably, it also includes a clip electric induction device, which includes an elastic induction part and an insulating part. The frame is connected to a low-voltage power supply, the insulating part is fixed on the frame, the elastic induction part is fixed on the insulating part, the elastic induction part is located on the outside of the clamp seat, and the elastic induction part is connected to a controller to detect whether there is a clip in the clamp seat.

[0032] Through the above technical solution, the setting of the clip electric induction device can detect whether a clip is installed in the clamp seat, so as to determine the subsequent work of each installation device. If there is no clip installed on the clip seat one, then the subsequent installation devices will not act on the clip seat until the clip seat rotates one circle and returns to the clip installation device one, and the clip is installed on the clip seat one under the action of the clip installation device one. When there is no clip installed on the corresponding clip seat two, each installation device will not act on the clip seat until the clip seat rotates again to the clip installation device two, and the clip is installed on the clip seat two under the action of the clip installation device two. Similarly, when the material picking device does not withdraw the assembled clip in the clip seat from the clip seat, the subsequent devices of the material picking device will not act on the clip seat until the clip seat rotates again to the material picking device, and the assembled clip in the clip seat is withdrawn under the action of the material picking device.

[0033] Preferably, it also includes a pivot ear shaping device, which is located between the clip mounting device one and the clip mounting device two, and the pivot ear shaping device includes an extrusion rod, the end of the extrusion rod is located outside the pivot ear of the clip, the extrusion rod is connected to the extrusion rod driving device, and the extrusion rod driving device drives the extrusion rods to move toward each other to squeeze the pivot ear inward.

[0034] By using the above technical solution, the types of clips can be reduced. Generally speaking, the clips are divided into large clips and small clips, and the distance between the two pivot ears of the small clip is smaller than that of the large clip; according to the distance between the two pivot ears. During assembly, the two pivot ears of the small clip are between the two pivot ears of the large clip.

[0035] Most of the existing clips are stamped from metal sheets, and the clip pivot ears themselves have a certain degree of deformation. By squeezing the extrusion rod, the pivot ears of one of the clips can be tilted toward the middle of the clip as a whole, thereby reducing the distance between the two pivot ears, so that only one size of clip is needed to realize the assembly of the clip.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: by changing the clamp seat and the clip installation device, the clip is transported and positioned in an upright position, avoiding the problem that the side of the clip is not flat and cannot be stably placed on its side, so that the two clips can be installed in the clamp seat in an upright state and spliced ​​together, thereby realizing the assembly of the entire clip.

[0060] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0061] 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.

[0062] An automatic assembly device for stationery clips includes a frame 1, in which a power device (not shown in the figure) is installed, and the power device can use a motor. A divider 50 is installed on the clamp seat 4, and the input shaft 51 of the divider 50 is connected to the power device through a chain or belt drive. A rotating disk 3 is installed on the output shaft 52 of the divider 50, and the power device drives the rotating disk 3 to rotate intermittently at equal angles through the divider 50. A plurality of clamp seats 4 are evenly distributed on the circumference of the rotating disk 3. A clip installation device 1 5, a pivot ear shaping device 62, a clip installation device 2 6, a torsion spring installation device 7, a pin installation device 8, a pin pressing device 9 and a material taking device 10 are installed on the frame 1 outside the rotating disk 3. The rear ends of the clip installation device 1 5, the clip installation device 2 6, the torsion spring installation device 7 and the pin installation device 8 are connected to the discharge port of the vibration disk for loading. The clips, torsion springs and pins are placed in the vibration disk, arranged under the action of the vibration disk and sent one by one into the clip installation device 1 5, the clip installation device 2 6, the torsion spring installation device 7 and the pin installation device 8.

[0063] like Figures 2~5 As shown, the clamp seat 4 includes a seat body 11, on which a clip seat 12, a clip seat 2 13 and a guide block 63 are arranged. The clip seat 12 and the guide block 63 are fixedly mounted on the seat body 11, and the clip seat 2 13 is slidably arranged between the clip seat 12 and the guide block 63. A guide rod 64 is arranged on one side of the clip seat 2 13, and the guide rod 64 is inserted in the guide block 63, so that the sliding direction of the clip seat 2 13 is limited. A return spring 22 is arranged between the clip seat 2 13 and the guide block 63, and the return spring 22 can make the clip seat 2 13 have a tendency to move toward the clip seat 1 12. In the absence of other external forces, the clip seat 2 13 contacts the clip seat 1 12 under the action of the return spring 22. A driving groove 28 is arranged on the guide rod 64, and the driving groove 28 is used to cooperate with the driving rod to drive the clip seat 2 13 to slide in a direction away from the clip seat 1 12. The seat body 11 and the guide block 63 are provided with through holes for the driving rod to be inserted into the driving groove 28 .

[0064] The clip seat 12 and the clip seat 2 13 are both provided with a clip placement groove 14, which extends along the width direction of the clip. The clip placement groove 14 includes a limit groove 19 at the lower end of the clamping part, and the lower end of the clamping part of the clip is inserted into the limit groove 19 at the lower end of the clamping part. At the same time, the two clip placement grooves 14 are slightly inclined to both sides of the vertical direction, so that the outer surface of the clip can be against and fit with the surface of the clip placement groove 14. When the two clips are placed in the clip placement groove 14, the pressing ends of the two clips are inclined to both sides of the clip seat 4, so that the upper end opening of the clip is larger, and the torsion spring can be installed between the two clips more smoothly. The clip seat 1 12 and the clip seat 2 13 are also provided with an installation cavity 20, and a magnetic part 21 is installed in the installation cavity 20. The magnetic part 21 can use a magnet, so that the iron clip can be adsorbed, so that the clip can be firmly adsorbed in the clip seat, and the clip is not easy to move in the clip seat.

[0065] like Figures 6-8 As shown, a clip installation device 5 is installed on the frame 1 outside the rotating disk 3, and the clip installation device 5 includes a discharge seat 15 and a clip driving device 79, and the clip driving device 79 can use a linear feeder. The discharge seat 15 is installed above the clip driving device 79. A clip discharge groove 16 is opened in the discharge seat 15, and the rear end of the clip discharge groove 16 is connected to the discharge port of the vibration disk, and the front end is aligned with the clip placement groove 14 of the clip seat 12. The clips are arranged and transported in the clip placement groove 14 along the clip width direction.

[0066] The front end of the discharge seat 15 is provided with an elastic positioning member 17, and the end of the elastic positioning member 17 is inserted into the clip discharge groove 16 to block and position the clip, so that the clip is arranged in the clip discharge groove 16 behind the elastic positioning member 16. The elastic positioning member 17 is horizontally inserted into the clip discharge groove 16 from the outside of the discharge seat 15. A longitudinal spring 65 is installed on the outside of the discharge seat 15, and the lower end of the longitudinal spring 65 is fixed to the discharge seat 15 by screws, so that the axis of the longitudinal spring 65 remains in a vertical state. A clip clamping and pushing device 18 is provided above the clip on the rear side of the elastic positioning member 17. The clip clamping and pushing device 18 clamps the upper end of the clip and drives the clip to push the elastic positioning member 17 away, so that the clip is installed in the clamp seat 4 from the front end of the clip discharge groove 16 through the elastic positioning member 17. One end of the elastic positioning member 17 on the outside of the discharge seat 15 is sleeved on the upper end of the longitudinal spring 65. The upper end of the longitudinal spring 65 can swing, so that the elastic positioning member 17 can be inserted into and withdrawn from the clip discharge groove 16.

[0067] The clamping piece clamping and pushing device 18 includes a clamping jaw 66 for clamping the upper end of the clamping piece, and a clamping jaw pushing cylinder 67 for pushing the clamping jaw 66 toward the clamping seat 4. The clamping jaw 66 is driven by a pneumatic finger 80 to clamp and release. The pneumatic finger 80 is installed at the front end of the clamping jaw pushing cylinder 67, and is pushed by the clamping jaw pushing cylinder 67 to extend toward the clamping seat 4 or retract toward the discharge seat 15.

[0068] like Fig. 9 and 10 As shown, the clip installation device 15 is provided with a pivoting ear shaping device 62 at the rear along the rotation direction of the rotating disk 3. The pivoting ear shaping device 62 comprises a squeezing rod 60 installed on two clamping fingers of the pneumatic finger 2 81, and the two squeezing rods 60 are respectively located on both sides of the pivoting ears of the clip installed in the clip seat 12. When the pneumatic finger 2 81 is clamped, the two squeezing rods 60 move toward each other, squeezing the pivoting ears of the clip installed on the clip seat 12, so that the pivoting ears are deformed toward the inside of the clip, thereby reducing the width between the two pivoting ears, so that when the two clips are laterally spliced, the pivoting ears of the squeezed clip can be inserted between the pivoting ears of the clip that is not squeezed.

[0069] like Figures 11-12 As shown, a clip installation device 26 and a clip seat driving device 25 are also installed on the outer side of the rotating disk 3. The specific structure of the clip installation device 26 is similar to that of the clip installation device 15, and is used to install the clip into the clip placement groove 14 of the clip seat 2 13. Before the clip installation device 26 installs the clip into the clip seat, the clip seat driving device 25 is activated first to drive the clip seat 2 13 to move away from the clip seat 12, so that when the clip is installed on the clip seat 2 13, it will not interfere with the clip installed in the clip seat 12.

[0070] A crossbeam 24 is mounted on the rotating disk 3, and a clip seat driving device 25 is fixed on the crossbeam 24. The clip seat driving device 25 is located above the rotating disk 3 as a whole and faces the clip seat 4 corresponding to the clip mounting device 2 6. The clip seat driving device 25 includes a mounting plate 68, on which a driving block pushing cylinder 69 is longitudinally mounted, and a driving block 70 is mounted at the lower end of the driving block pushing cylinder 69, and a driving inclined surface 2 71 is arranged on the side of the driving block 70 facing the clip seat 4. A driving rod guide block 72 is also mounted on the mounting plate 68, and the driving rod 26 is horizontally inserted in the driving rod guide block 72. A driving inclined surface 1 27 is arranged at the front end of the driving rod 26, and the driving inclined surface 1 27 is arranged to face away from the clip seat 12. When the driving rod 26 is inserted into the driving groove 28 on the clip seat 2 13, the driving inclined surface 1 27 drives the clip seat 2 13 to slide in a direction away from the clip seat 12. A driving rod limiting plate 83 is provided at the front end of the driving rod guide block 72, and a driving rod extension opening 84 is provided on the driving rod limiting plate 83. The front end section of the driving rod 26 is small, and it can be extended from the driving rod extension opening 84. The rear end section of the driving rod 26 is large, and it cannot be extended from the driving rod extension opening 84. A return spring 73 is installed in the driving rod guide block 72, and the front end of the driving rod 26 is inserted outside the return spring 73. The front end of the return spring 73 contacts the driving rod limiting plate 83, and the rear end face of the driving rod 26 contacts the rear end of the return spring 73. Under the action of the return spring 73, the rear end of the driving rod 26 contacts the second driving inclined surface 71. When the driving block push cylinder 69 pushes the driving block 70 downward, the driving inclined surface 2 71 pushes the driving rod to move toward the clamp seat 4, so that the front end of the driving rod 26 extends out of the driving rod extension port 84 and is inserted into the driving groove 28 of the clip seat 2 13, thereby pushing the clip seat 2 13 to move away from the clip seat 1 12. After the clip is installed on the clip seat 2 13, the driving block push cylinder 69 retracts, and the driving rod 26 exits the driving groove 28 under the action of the return spring 73. In this process, the clip seat 2 13 is reset under the action of the reset spring 22, slides laterally toward the clip seat 1 12, and contacts the clip seat 1 12, so that the clips installed on the clip seat 1 12 and the clip seat 2 13 are laterally spliced.

[0071] A torsion spring installation device 7 and a pin installation device 8 are installed behind the clip installation device 2 6. The torsion spring installation device 7 and the pin installation device 8 correspond to the same clamp seat 4, and the torsion spring and the pin are installed in the clamp seat 4. During operation, the torsion spring installation device 7 first installs the torsion spring between the upper ends of the two clips, and then the pin installation device 7 inserts the pin into the pin hole of the clip and the inner ring of the torsion spring, and then the torsion spring installation device 7 and the pin installation device 8 are reset, so that the clip can realize the installation of the torsion spring and the pin.

[0072] The torsion spring installation device 7 includes a discharge seat 29 and a torsion spring driving device 30, and the torsion spring driving device 30 can use a linear feeder. The discharge seat 29 is installed above the linear feeder, and a torsion spring discharge groove 31 is provided in the discharge seat 29, and the rear end of the torsion spring discharge groove 31 is connected to the discharge port of the vibration plate. Under the action of the vibration plate, the torsion springs enter the torsion spring discharge groove 31 one by one, and move to the front end of the torsion spring discharge groove under the action of the torsion spring driving device 30. A torsion spring storage seat 32 is provided at the front end of the torsion spring discharge groove 31, and the torsion spring storage seat 32 is fixed on the crossbeam 24. A torsion spring storage groove 33 is provided in the torsion spring storage seat 32, and the side of the torsion spring storage groove 33 is connected to the torsion spring discharge groove 31, and a feeding groove 34 is provided below the torsion spring storage groove 33, and the cross section of the feeding groove 34 is smaller than the cross section when the torsion spring is not compressed. A push rod 35 is arranged above the feed trough 34 and can be retracted and inserted into the feed trough 34. The push rod 35 is driven by a cylinder. The torsion spring storage seat 32 is arranged in a split body. The torsion spring storage seat 32 includes a fixed portion 74 and a movable portion 75. The movable portion 75 is located at the lower end of the torsion spring storage seat 32, and the feed trough 34 passes through the movable portion 75 longitudinally. A longitudinal driving device 36 is installed on the side of the torsion spring storage seat 32. The longitudinal driving device 36 drives the movable portion 75 to move toward the clamp seat 4, so that the lower end of the movable portion 75 is inserted between the pressing portions of the two clips installed in the clamp seat 4. The longitudinal driving device 36 includes a longitudinally arranged cylinder and a mounting block connected to the cylinder. The movable portion is fixed on the mounting block and can move up and down with the mounting block.

[0073] When installing the torsion spring, the torsion spring conveyed from the vibration plate is moved into the torsion spring storage seat 32, and then the push rod 35 moves downward to press the torsion spring directly below the push rod 35 into the feeding trough 34. When the push rod 35 presses the torsion spring into the feeding trough 34, it also prevents other torsion springs from entering the feeding trough 34. While the push rod 35 pushes the torsion spring to move toward the clamp seat 4, the moving part 75 also moves downward under the action of the push rod 35 and the longitudinal drive device 36, and the lower end of the moving part 75 is inserted between the two clamps, so that the torsion spring can be accurately installed between the two clamps.

[0074] When the torsion spring is installed between the two clamps, the pin installation device 8 works. The pin installation device 8 includes a discharge seat 37, which is located outside the clamp seat 4 to avoid interference with the torsion spring installation device 7. The discharge seat 37 is installed above the pin drive device 38, and the pin drive device 38 can use a linear feeder. Fig.18As shown, a pin discharge groove 39 is provided in the discharge seat 37. A pin material moving mechanism 40 is provided at the front end of the pin discharge groove 39. The pin material moving mechanism 40 includes a fixed block 41. A pin material storage seat 42 is slidably provided in the fixed block 41. A pin material storage groove 43 is provided on the pin material storage seat 42. A cover plate 77 is provided on the fixed block 41. Two insertion holes 78 are provided on the cover plate 77. The insertion hole 78 on the left side of the cover plate 77 faces the pin discharge groove 39. When the pin material storage seat 42 moves to the left side of the fixed block 41, the pin material storage groove 43 on the pin material storage seat 42 faces the insertion hole 78 and the pin discharge groove 39. The pin enters the pin material storage groove 43 under the action of the linear feeder. The cover plate 77 can prevent the pin from falling from the pin material storage groove 43 when the pin material storage seat 42 slides. When the pin storage seat 42 slides to the right end of the fixed block 41, the pin storage slot 43 faces the insertion hole 78 on the right side of the cover plate 77, and the insertion hole 78 is inserted with a pin 45. A pin feed seat 44 is installed on the fixed block 41 at the front end of the pin 45. When the pin 45 is ejected, the pin in the storage slot can be pushed into the pin feed seat 44, and the front end outlet of the pin feed seat 44 faces the pin hole on the clip. As the pin 45 continues to be ejected, the pin is ejected from the front end of the pin feed seat 44 and inserted into the pin hole, thereby realizing the installation of the pin. The specific structure of the pin feed seat 44 has been described in more detail in the Chinese patents No. 201711482682.4 and 201721919315.1, which will not be repeated here. The pin storage seat 42 and the pin 45 are driven by a cylinder to slide left and right.

[0075] When the pin is installed in the pin hole, the pin 45 is retracted, and the push rod 35 and the moving part 75 move upward and withdraw from between the two clips. Then the clip with the torsion spring and the pin installed is rotated to the pin pressing device 9 under the drive of the rotating disk 3.

[0076] like Fig.19 As shown, the pin pressing device 9 is arranged horizontally and mounted above the clamp seat 4, wherein two punches 85 are arranged horizontally on both sides of the pin, respectively, to punch the pin so that the end of the pin is deformed so that it can be fixed on the clip. The specific transmission structure of the pin pressing device 9 can be referred to as shown in the Chinese patent with patent number 201721919992.3, which will not be repeated here.

[0077] A material taking device 10 is arranged behind the pin pressing device 9, and the material taking device 10 comprises a fixing frame 46, on which a material taking driving device 47 is mounted, and a push rod mounting block 48 is connected to the front end of the material taking driving device 47, and a push rod 49 is mounted on the push rod mounting block 48. The push rod 49 is located at the back of the clamp seat 4, and under the action of the material taking driving device 47, the push rod 49 can pass through the clamp seat 4 along the width direction of the clamp and contact the clamp, so as to withdraw the assembled clamp in the clamp seat 4.

[0078] In addition, a rotation angle sensor 53 is also installed on the frame 1. The rotation shaft 54 ​​of the rotation angle sensor 53 is connected to the input shaft 51 of the divider 50. The two rotate at the same angle, that is, when the input shaft 51 of the divider 50 rotates at an angle α, the rotation shaft 54 ​​of the rotation angle sensor 53 also rotates at an angle α. The rotation angle sensor 53 can detect the rotation angle of the input shaft 51. The rotation angle sensor 53 can use an encoder, and the rotation angle sensor 53 is connected to the controller 2. When the rotation shaft 54 ​​of the rotation angle sensor 53 rotates, the rotation angle sensor 53 outputs a pulse signal to the controller 2. The controller 2 counts the pulse signals input by the rotation angle sensor 53, thereby obtaining the rotation angle of the input shaft 51 and monitoring the rotation angle of the input shaft 51. At the same time, the controller 2 controls the action sequence of each driving member in the clip installation device 1 5, the clip installation device 2 6, the pivot ear shaping device 62, the torsion spring installation device 7, the pin installation device 8, the pin pressing device 9 and the material taking device 10 according to the rotation angle of the input shaft 51. When the clip assembly machine is working, the input shaft 51 of the divider 50 rotates continuously at a constant speed, and the rotation angle sensor 53 cooperates with the controller 2 so that the above devices do not work when the input shaft 51 drives the rotating disk 3 to rotate. When the input shaft 51 does not drive the rotating disk 3 to rotate, the driving parts in each device are controlled to work in a predetermined order to achieve smooth assembly of the clip. The controller 2 controls the driving parts in each device according to the rotation angle of the input shaft 51, so that the device can be coordinated with the intermittent rotation state of the rotating disk 3.

[0079] A switch 55 is also mounted on the frame 1. The rotation angle sensor 53 and the input shaft 51 are connected via a coupling 86. A positioning portion 56 cooperating with the switch 55 is provided on the coupling 86. The switch 55 can use a proximity switch, and the switch 55 is connected to the controller 2. The positioning portion 56 is a screw fixed on the coupling 86. Every time the input shaft 51 rotates one circle, the switch 55 senses the positioning portion 56 once, so that the switch 55 transmits a signal to the controller 2. The controller 2 resets the rotation angle of the encoder (i.e., the count value is reset to zero) according to the signal given by the switch 55, thereby avoiding the error accumulation of the encoder during long-term operation, affecting the detection accuracy of the rotation angle and the coordination of various components. By adjusting the position of the positioning portion 56 or the switch 55, when the switch 55 is facing the positioning portion 56, the input shaft 51 will drive the rotating disk 3 to rotate. When the positioning portion 56 rotates to the position facing the switch 55, the input shaft 51 immediately drives the rotating disk 3 to rotate.

[0080] The assembly machine also includes a clip electric induction device 57, which includes an elastic induction member 58 and an insulating member 59. Fig. 20As shown, the clip electric induction device is installed behind the material taking device 10 to detect whether there is still a clip installed in the clamp seat 4 passing through the material taking device 10. The insulating member 59 is installed on the frame 1 through the fixing frame 46, and the elastic induction member 58 is fixed on the insulating member 59. The elastic induction member 58 is installed above the place where the clamp seat 4 passes. When a clip is installed in the clamp seat 4 and passes under the elastic induction member 58, the elastic induction member 58 can conflict with the clip in the clamp seat 4. The elastic induction member 58 can be formed by bending a metal wire, and the elastic induction member 58 is connected to the controller 2. When working, the frame 1 is connected to the low-voltage power supply. The clip is made of metal material, and the frame 1, the divider 50, the rotating disk 3 and the clamp seat 4 are also made of conductive material. When the frame 1 is connected to the low-voltage power supply, the corresponding clip installed on the clamp seat 4 is also charged. The elastic sensing member 58 is connected to the controller 2. When a clip installed in the clamp seat 4 passes under the elastic sensing member 58, conduction occurs between the elastic sensing member 58 and the clip, thereby transmitting an electrical signal to the controller 2 to detect whether a clip is installed in the clamp seat 4.

[0081] The controller 2 may use a programmable controller 2 (PLC), and the control of the entire machine can be achieved by programming the controller 2.

[0082] The action process of this clip assembly machine can be set as follows:

[0083] 1. The machine starts, the motor rotates, and each vibration plate and linear feeder work. When the motor rotates, it drives the input shaft 51 to rotate at a constant speed until the switch 55 is facing the positioning part 56. The switch 55 sends a reset signal to the controller 2. At this time, the controller 2 recounts the pulse signal input by the rotation angle sensor 53, and the controller 2 detects the rotation angle of the input shaft 51.

[0084] 2. The motor drives the input shaft 51 to rotate, and the input shaft 51 drives the rotating disk 3 to rotate. When the input shaft 51 rotates to α degrees, the rotating disk 3 stops rotating. At this time, the clamping seat 4 on the rotating disk 3 is facing each installation mechanism and the material taking mechanism.

[0085] 3. The input shaft 51 continues to rotate. When the input shaft 51 rotates to the angle B1 (B1 is greater than α), the pneumatic finger 1 80 in the clip installation device 1 5 clamps the upper end of the clip below it; the pneumatic finger 2 81 in the pivot ear shaping device 62 drives the extrusion rod 60 to squeeze the clip pivot ear to deform it; the drive block in the clip seat drive device 25 pushes the cylinder 69 to push the drive rod 26 into the clip seat 2 13, so that the clip seat 2 13 moves to the outside of the clip seat 1 12; the cylinder 1 87 in the torsion spring installation device 7 pushes the push rod 35 It moves downward, pressing the torsion spring into the feed trough 34. During this process, the moving part 75 also moves downward and is inserted between the upper ends of the two clamps. The torsion spring is also pushed to the lower end of the feed trough 34 and is between the upper ends of the two clamps. At the same time, the cylinder 4 90 of the longitudinal drive device 36 extends downward under the drive of the moving part 75; at the same time, the cylinder 2 88 in the pin installation device 8 pushes the pin storage seat 42 to move to the right; the punch 85 of the pin pressing device 9 extends out to punch the pin; the material taking drive device 47 in the material taking device 10 drives the push rod 49 to push the clamp out of the clamp seat 4.

[0086] 4. The input shaft 51 continues to rotate. When the input shaft 51 rotates to the angle B2 (B2 is greater than B1), the jaw pushing cylinder 67 in the clip installation device 5 is pushed out to send the clip into the clamp seat 4; the pneumatic finger 80 in the pivot ear shaping device 62 is released; the pneumatic finger 80 in the clip installation device 2 6 is clamped; the cylinder 3 89 in the pin installation device 8 is pushed out to insert the pin 45 into the fixed block 41, and the pin is pushed out from the front end of the pin feed seat 44 and inserted into the pin hole of the clip; the punch 85 in the pin pressing device 9 is reset; the material taking drive device 47 in the material taking device 10 is reset.

[0087] 5. The input shaft 51 continues to rotate. When the input shaft 51 rotates to an angle B3 (B3 is greater than B2), the pneumatic finger 1 80 in the clip installation device 1 5 is released; the clamping claw pushing cylinder 67 in the clip installation device 2 6 extends; the cylinder 4 90 in the torsion spring installation device 7 retracts, so that the moving part 75 is pulled out from between the upper ends of the two clips; the cylinder 3 89 in the pin installation device 8 retracts, driving the pin 45 to withdraw from the fixed block 41;

[0088] 6. The input shaft 51 continues to rotate. When the input shaft 51 rotates to the angle B4 (B4 is greater than B3), the clamping claw pushing cylinder 67 in the clip installation device 1 5 retracts; the pneumatic finger 1 80 in the clip installation device 2 6 is released; the cylinder 1 87 in the torsion spring installation device 7 retracts, driving the push rod 35 to withdraw from between the two clips; the cylinder 2 88 in the pin installation device 8 retracts, driving the pin storage seat 42 to move to the left;

[0089] 7. The input shaft 51 continues to rotate. When the input shaft 51 rotates to an angle B5 (B5 is greater than B4), the clamping claw pushing cylinder 67 in the second clamping piece installation device 6 retracts.

[0090] 8. The input shaft 51 continues to rotate. When the input shaft 51 rotates to an angle B6 (B6 is greater than B5 and less than 360 degrees), the driving block push cylinder 69 retracts and the driving rod 26 withdraws from the driving groove 28 on the clip seat 13.

[0091] 9. The input shaft 51 continues to rotate until the positioning portion 56 faces the switch element 55. The controller 2 receives a signal from the switch element 55, resets the rotation angle of the input shaft 51, and starts the next cycle.

[0092] 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.
