The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] like Figures 1 to 14As shown, this application discloses an automatic clamp assembly machine, including a base 1. A turntable 2 is rotatably mounted in the middle of the base 1. The turntable 2 can be disc-shaped and horizontally arranged. A drive structure 3 for driving the turntable 2 to rotate is connected to the middle of the turntable 2. Specifically, the drive structure 3 can be a drive motor or a cam divider as used in the prior art. The output shaft of the cam divider is connected to the turntable 2 so as to drive the turntable 2 to rotate intermittently. The edge of the base 1 surrounds the turntable 2 and is sequentially provided with a clamp placement mechanism 4, a clamp closing mechanism 5, a spring pin insertion mechanism 6, a pin riveting mechanism 7, and a feeding mechanism 8. The edge of the turntable 2 corresponds to the clamp placement mechanism. The feeding mechanism 4, clamping plate closing mechanism 5, spring pin insertion mechanism 6, pin riveting mechanism 7, and unloading mechanism 8 are equipped with clamping plate positioning mechanisms 9. At least five clamping plate positioning mechanisms 9 are provided, each corresponding to one of the clamping plate positioning mechanism 9, clamping plate closing mechanism 5, and spring pin insertion mechanism 6. Of course, more clamping plate positioning mechanisms 9 can be provided as needed. Each clamping plate positioning mechanism 9 includes a fixed base 10 fixedly mounted on the turntable 2, which is detachably mounted on the turntable 2 using screws. The fixed base 10 has two movable seats 11, and a drive assembly that drives the two movable seats 11 to move towards each other. Each movable seat 11 is equipped with... The clamping plate positioning block 12 has a clamping plate positioning groove 13 to limit the clamping plate. The driving assembly includes a driving block 14. The fixed base 10 has a sliding groove 15 that slides with the driving block 14. The sliding groove 15 is vertically arranged. The driving block 14 has a wedge-shaped driving surface 16 that cooperates with the moving base 11 and a fixed abutment surface 17. The clamping plate positioning block 12 has a driving groove 78 that cooperates with the wedge-shaped driving surface 16 and the fixed abutment surface 17. The wedge-shaped driving surface 16 is connected to the fixed abutment surface 17. The fixed base 10 also has a guide rod 18. The two moving bases 11 slide with the guide rod 18. A compression spring is fitted on the guide rod 18. Both ends abut against the movable seat 11 respectively. When the two driving blocks 14 move downward, the wedge-shaped driving surface 16 can abut against the bottom of the driving groove 78 and drive the two clamping positioning blocks 12 to move towards each other during the downward movement. When the two driving blocks 14 move downward until the fixed abutting surface 17 abuts against the bottom of the driving groove 78, the two clamping positioning blocks 12 move towards each other to the closest distance. At this time, the two driving blocks 14 stop moving and can keep the position of the clamping positioning blocks 12 fixed. During this process, the compression spring will be compressed. When the two driving blocks 14 move upward to the initial position, under the action of the compression spring, the clamping positioning blocks 12 can also be driven to move to the initial position.

[0020] The automatic clamp assembly machine of the present invention realizes the automated assembly of clamps by setting up a clamp inserting mechanism 4, a clamp closing mechanism 5, a spring pin inserting mechanism 6, a pin riveting mechanism 7 and a feeding mechanism 8. Furthermore, by setting up a clamp positioning mechanism 9 on the turntable 2, the clamps can be accurately positioned and assembled, which improves the subsequent installation accuracy of springs and pins, thereby improving the assembly accuracy and efficiency of clamps.

[0021] In this application, the clamping plate placement mechanism 4 may include a first clamping plate placement mechanism 19, a second clamping plate placement mechanism 20, and a positioning component 21. Both the first clamping plate placement mechanism 19 and the second clamping plate placement mechanism 20 include a clamping plate feeding vibratory feeder 22, a clamping plate moving component, and a rotating unloading component. The clamping plate feeding vibratory feeder 22 can adopt an existing structure. The discharge end of the clamping plate feeding vibratory feeder 22 is connected to a clamping plate conveying groove 23, which can limit the clamping plate, ensuring stable conveying of the clamping plate along the clamping plate conveying groove 23. The clamping plate moving component includes a material transfer block. 24, and a material transfer block driving device 25 that drives the material transfer block 24 to move in the horizontal and vertical directions; the rotary unloading assembly includes a rotary block 26 and a rotary device 27 that drives the rotary block 26 to rotate; the rotary block 26 is provided with a clamping plate limiting groove 28 for limiting the clamping plate; the positioning assembly 21 includes a positioning seat 29 and a positioning seat driving device 30 that drives the positioning seat 29 to move in the vertical direction; the positioning seat 29 is provided with a first positioning block 31 and a second positioning block 32; in this application, the two clamping plates of the clamp have the same structure, such as... Figure 15 As shown, connecting pieces 76 are symmetrically arranged on both sides of the material transfer block 24. Each connecting piece 76 has mounting holes 77 for installing pins. The material transfer block drive device 25 may include a mounting frame with a horizontal guide rail. A horizontal slide block is slidably mounted on the horizontal guide rail and connected to a horizontal drive cylinder that drives it to move along the horizontal guide rail. A vertical guide rail is provided on the horizontal slide block. The material transfer block 24 is slidably engaged with the vertical guide rail and connected to a vertical drive cylinder that drives it to move along the vertical guide rail. The material transfer block 24 is equipped with a material transfer head. Driven by the material transfer block drive device 25, the material transfer block 24 can be moved, allowing the material transfer head to be inserted between the two connecting pieces 76. Then, the transfer block 24 is driven to move toward the rotating block 26, thereby transferring the clamping piece to the clamping piece limiting groove 28 and placing it horizontally. The limiting groove has an inlet and an outlet on both sides. The rotating shaft can be a rotary motor. The rotary motor controls the rotating block 26 to rotate 90°, so that the clamping piece slides from the outlet into the clamping piece positioning groove 13. Before the clamping piece slides down, the positioning seat drive device 30 drives the positioning seat 29 to move downward, so that the first positioning block 31 and the second positioning block 32 are respectively inserted into the front and rear ends of the two rotating blocks 26, thereby limiting the front and rear ends of the two clamping pieces to ensure that the clamping pieces slide accurately into the clamping piece positioning groove 13.

[0022] In the above embodiments, the clamping plate placement mechanism 4 may further include a clamping plate assembly, which includes a pressure plate 33 and a pressure plate driving device 34 for driving the pressure plate 33 to move in the vertical direction. The pressure plate 33 includes a pressure head that can extend between the two connecting plates 76. The pressure plate driving device 34 controls the pressure plate 33 to move downward, so that the pressure plate 33 extends between the two connecting plates 76 to press the clamping plate into the clamping plate conveying groove 23, thereby stopping the conveying of the clamping plate.

[0023] In this application, the clamping mechanism 5 may include an upper pressing block 35, a lower pressing block 36, a first push block 37, a second push block 38, and a first driving member 39 for driving the upper pressing block 35, the lower pressing block 36, the first push block 37, and the second push block 38 to move vertically. The upper pressing block 35 and the lower pressing block 36 are symmetrically arranged above and below the turntable 2. When assembling the two clamping pieces, the two connecting pieces 76 of one clamping piece need to be inserted into the inner side of the two connecting pieces 76 of the other clamping piece, so that the mounting holes 77 on the two inserted connecting pieces 76 are aligned, so as to facilitate the subsequent pinning. For insertion and installation, the first driving component 39 can be a cylinder. The cylinder drives the upper pressure block 35 and the lower pressure block 36 to move downward and upward toward the two connecting pieces 76 of one of the clamping pieces, respectively, thereby applying pressure to the two connecting pieces 76, causing the two connecting pieces 76 to bend and slightly close together. Then, the first push block 37 and the second push block 38 are driven to move downward, thereby pushing the driving block 14 to move downward, thereby driving the two clamping piece positioning blocks 12 to move toward each other, so that the bent two connecting pieces 76 can be inserted into the two connecting pieces 76 of the other clamping piece, realizing the precise assembly of the clamping pieces.

[0024] In this application, the spring pin insertion mechanism 6 includes a spring insertion unit 40, a pin insertion unit 41, and a limiting plate 42. The spring insertion unit 40 includes a spring vibratory feeder 43, a spring moving assembly, and a pushing assembly. The spring vibratory feeder 43 can use an existing structure. The discharge end of the spring vibratory feeder 43 is connected to a spring conveying track 44. The spring moving assembly includes a moving rod 45 and a moving rod drive device 46 that drives the moving rod 45 to move in the horizontal and vertical directions. The moving rod drive device 46 can adopt the same structure as the material transfer block drive device 25. The moving rod 45 can be inserted into the hole in the middle of the spring, thereby pushing the spring to the pushing assembly. The pushing assembly includes a push rod 47 and a push rod drive that drives the push rod 47 to move back and forth. Device 48 drives push rod 47 forward via push rod drive device 48, which can accurately push the spring delivered to the front of push rod 47 to the mounting hole 77 between the two clamping plates. The pin loading unit 41 includes a pin vibratory plate 49, a guide cylinder 50, a pin conveying assembly, a pin positioning clamp 51, and a pin pushing assembly. The pin vibratory plate 49 can adopt an existing structure. The output end of the pin vibratory plate 49 is connected to the guide cylinder 50 through an air pipe, and can convey only one pin into the guide cylinder 50 at a time. The pin conveying assembly includes a pin conveying block 52 and a pin conveying block drive device 53 that drives the pin conveying block 52 to move back and forth. The pin conveying block 52 is provided with a receiving hole 54. The pin positioning clamp 51 includes two symmetrically arranged movable clamping blocks. 55. A limiting hole 56 is provided between the two movable clamping blocks 55 to limit the pin. The pin pushing assembly includes a pin pushing block 57 and a pin pushing block driving device 58 that drives the pin pushing block 57 to move vertically. The guide cylinder 50 is vertically arranged, which allows the conveyed pin to fall accurately vertically into the receiving hole 54 along the guide cylinder 50. Both the pin conveying block driving device 53 and the pin pushing block driving device 58 can be cylinders. The cylinder drives the pin conveying block 52 to move towards the pin positioning clamp 51, so that the pin in the receiving hole 54 falls into the limiting hole 56. The limiting hole 56 includes an upper section with a larger diameter and a lower section with a smaller diameter. The upper section allows the entire pin to pass through, while the lower section only allows the front end of the pin to pass through. The nail head at its rear end cannot pass through, thus limiting the pin. The two movable clamping blocks 55 are elastically mounted on the mounting frame by springs. Under the action of the spring force, the two movable clamping blocks 55 close. When the cylinder drives the pin pushing block 57 to move downward and extend into the limiting hole 56, it can squeeze open the two movable clamping blocks 55, thereby accurately pushing the pin into the mounting holes 77 of the two clamping pieces. The limiting plate 42 is connected to a pressure plate driving device 34 that drives it to move in the vertical direction. The limiting plate driving device 59 can also be a cylinder. Before the spring and the pin are installed, the cylinder drives the limiting plate 42 to move downward, thereby making the limiting plate 42 press the clamping pieces into the clamping piece positioning groove 13 to prevent the clamping pieces from moving during the installation of the spring and the pin.

[0025] In the above embodiment, the spring loading unit 40 may further include a spring limiting assembly, which includes an insertion rod 60, two limiting rods 61, and a second driving member 62 that drives the insertion rod 60 and the two limiting rods 61 to move vertically. The second driving member 62 may be a cylinder. The insertion rod 60 can be inserted into the hole in the middle of the spring. During the spring conveying process, the cylinder drives the two limiting rods 61 to move upward, so that the two limiting rods 61 abut against the two ends of the spring, thereby limiting the spring at the foremost end of the conveying end. Then, the cylinder drives the insertion rod 60 to move upward, so that the cylinder inserts into the hole of the next spring to limit the next spring. Then, the two limiting rods 61 are controlled to move downward, so that the foremost spring is not limited. At this time, the spring moving assembly can move the foremost spring to the front of the pushing assembly, thereby achieving precise conveying of the spring.

[0026] Furthermore, the spring loading unit 40 may also include a spring positioning block 63 and a spring guide block 64. The spring guide block 64 is provided with a spring guide groove 65. The spring positioning block 63 can position the spring so that the spring is accurately pushed to the front of the push assembly. The spring guide groove 65 is provided with recesses that respectively cooperate with the two ends of the spring, thereby limiting the spring and allowing the spring to be accurately pushed along the spring guide groove 65. After the spring is pushed into the spring guide groove 65, its two ends close to a certain extent so as to push the spring into the two clips.

[0027] In this application, the pin riveting mechanism 7 includes an upper pressure rod 66 and a lower pressure rod 67, as well as an upper pressure rod drive device 68 and a lower pressure rod drive device 69 that drive the upper pressure rod 66 and the lower pressure rod 67 to move in the vertical direction, respectively. The upper pressure rod drive device 68 can be a cylinder, and the lower pressure rod drive device 69 can be a cam drive structure 3. During riveting, the upper pressure rod 66 is driven by the cylinder to move downward and abut against the head of the anchor, and then the lower pressure rod 67 is driven to move upward to flatten the front end of the anchor, so as to realize the installation of the pin.

[0028] In this application, the unloading mechanism 8 may include an upper top block 70 and a movable gripper 71. The upper top block 70 is connected to an upper top block drive device 72 that drives it to move in the vertical direction. The upper top block 70 is provided with two protrusions 73 that can abut against two drive blocks 14 on the same fixed seat 10. The movable gripper 71 is connected to a movable gripper drive device 74 that drives it to move in the horizontal and vertical directions. The movable gripper drive device 74 may adopt the same structure as the material transfer block drive device 25. The upper top block drive device 72 may be a cylinder. The cylinder drives the upper top block 70 to move upward, so that the two protrusions 73 simultaneously push the two drive blocks 14 to move upward, so that the two movable seats 11 move to the initial position under the elastic force of the compression spring, thereby causing the clamping plate positioning block 12 to release the assembled clamp. The movable gripper drive device 74 drives the movable gripper 71 to clamp the clamp out of the clamping plate positioning mechanism 9. The unloading mechanism 8 also includes an unloading trough 75 located below the movable gripper 71. The unloading trough 75 is inclined downwards, and the clamped clamp can be clamped into the unloading trough 75 and transported to the container through the unloading trough 75 to realize the automatic unloading and collection of the clamp.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of the technical solutions of the present invention.
