Description

Technical Field

[0001] The invention relates to the field of hair clipper torsion spring assembly, in particular to a full-automatic hair clipper torsion spring accessory assembly device. Background Art

[0002] Barber clippers are a very important electric device in the current haircutting process. Hair can be cut quickly and effectively using barber clippers. Compared with the method of scissors, it greatly reduces the workload of the barber and also reduces the fatigue of the barber during the haircutting process. For people, haircutting can be achieved at home, so barber clippers are becoming more and more widely used.

[0003] The blade spring in the cutter head mainly relies on manual gripping of the spring seat of the hair clippers to clamp the torsion spring on the spring seat. During the above operation process, due to manual operation, the processing efficiency is low, and it is easy to install incorrectly or miss during the long assembly process. The end hook of the torsion spring also needs to be connected with the mounting hole of the moving blade. Most of the existing technologies are connected manually. When operating this process, a small number of existing automated equipment may easily cause the end hook to not be completely inserted into the mounting hole, resulting in the moving blade not being assembled in place. The existing equipment cannot simulate the manual installation process, and the overall equipment occupies a large area and the process is cumbersome, so it cannot be promoted on a large scale.

The component 22 is horizontally arranged on the third mounting frame 21, the first lifting drive component 23 is arranged on the output end of the horizontal drive component 22, the first lifting drive component 23 includes a lifting mounting frame 231 that is lifted and lowered, the clamping component 24, the rotating drive component 25 and the hook clamping component 26 are all installed on the lifting mounting frame 231, the second mounting frame 41 is located next to the first mounting frame 31, the third mounting frame 21 is located directly above the first mounting frame 31, the fixed seat 33 is fixedly installed on the side of the first mounting frame 31 close to the second mounting frame 41, the clamping seat 32 is horizontally slidably arranged on the first mounting frame 31, and the first limit baffle 36 is fixedly installed on the working platform 5 and the length direction is perpendicular to the sliding direction of the clamping seat 32.

[0035] The present invention can automatically realize the assembly process of the hair clipper assembly 1, can simulate the manual installation process, can ensure the accuracy of assembly, and can improve the installation efficiency, integrate the overall assembly process, reduce the equipment footprint and reduce the production cost of the equipment, and improve the application range of the equipment. When assembling the torsion spring 11, the end of the end hook 114 can be reciprocated to ensure that it can be accurately inserted into the installation hole 131, that is, to ensure the accuracy of the assembly connection.

[0036] It is worth mentioning that the working platform 5 is also equipped with a stationary blade loading robot, a torsion spring vibration loading platform, a moving blade loading transmission belt and a discharging conveyor belt. The stationary blade loading robot, the torsion spring vibration loading platform, the moving blade loading transmission belt and the discharging conveyor belt are all prior arts, which are not shown in the figure and will not be described here. The preferred positions of the above-mentioned devices are as follows: the torsion spring vibration loading platform is located below the loading end of the horizontal drive assembly 22, the moving blade loading transmission belt is located between the first mounting frame 31 and the second mounting frame 41, and the discharging conveyor belt is located directly below the first mounting frame 31.

[0037] When the present invention is automatically assembled, the static blade 12 is loaded into the clamping mechanism 3 by the static blade loading robot, the static blade 12 is positioned and clamped by the clamping mechanism 3, and the static blade 12 located between the clamping seat 32 and the fixed seat 33 is gradually clamped by sliding the clamping seat 32, and is automatically positioned during the clamping process. After the loading of the static blade 12 is completed, the loading operation of the dynamic blade 13 is carried out through the operation of the dynamic blade assembly mechanism 4. The second mounting frame 41 is used to install the dynamic blade assembly mechanism 4 next to the first mounting frame 31. The displacement of the first pushing frame 42 drives the blade clamping plate 43 installed thereon to move synchronously. The dynamic blade feeding conveyor is located between the first mounting frame 31 and the second mounting frame 41. When the first pushing frame 42 moves to the material picking position, the two blade clamping plates 43 approach each other, and the central transmission seat 132 located between the two blade clamping plates 43 is clamped, and the dynamic blade 13 is automatically positioned and clamped during the clamping process. After completing the clamping of the dynamic blade 13, the first pushing frame 42 continues to push the first pushing frame 42 to the top of the static blade 12 to complete the assembly process of the dynamic blade 13. When the torsion spring assembly mechanism 2 is working, the horizontal drive component 22 drives the first lifting drive component 23 to move as a whole to the material picking station (the position for picking up the torsion spring 11), that is, it is located above the discharge end of the torsion spring vibration loading platform, and the first lifting drive component 23 drives the lifting mounting frame 231 to descend, and the clamping component 24, the rotating drive component 25 and the hook clamping component 26 installed thereon are synchronously displaced, and then the torsion spring 11 is picked up by the rotating drive component 25. After the material picking is completed, the torsion spring 11 is driven by the horizontal drive component 22 and the first lifting drive component 23 to be transferred to above the assembly station (the position for installing the torsion spring 11). The rotating driving assembly 25 drives the torsion spring 11 to deflect a certain angle, and the connecting rod 112 is clamped on the buckle 122 of the static blade 12. The spring coil 111 is pressed into the clamping groove 123 of the spring seat 121 through the pressing assembly 24. During the pressing process, the rotating driving assembly 25 releases the transmission of the torsion spring 11. The hook clamping assembly 26 is used to accurately clamp the end hook 114 into the mounting hole 131 of the moving blade 13, so as to complete the overall installation process. When it is necessary to unload the material, the clamping seat 32 is reset and retracted, and the hair clipper assembly 1 mainly supported by the clamping seat 32 moves synchronously with the clamping seat 32, and is blocked and limited by the first limit baffle 36 during the displacement process, so that the hair clipper assembly 1 slides between the clamping seat 32, and the hair clipper assembly 1 is gradually pushed away from the clamping seat 32, so that the hair clipper assembly 1 falls onto the unloading conveyor installed under the third mounting frame 21, thereby completing the unloading process.

[0038] The hair clipper assembly 1 includes a torsion spring 11, a stationary blade 12 and a movable blade 13. The torsion spring 11 is composed of a spring coil 111, a connecting rod 112, a long torsion arm 113 and an end hook 114 (combined with Figure 2 and Fig.12), the static blade 12 is provided with a spring seat 121 for installing the torsion spring 11 and a buckle 122 for clamping the connecting rod 112, two mounting holes 131 for clamping the end hooks 114 are provided at both ends of the dynamic blade 13, a central transmission seat 132 is provided in the middle of the dynamic blade 13, and the clamping seat 32 includes a first blanking notch 321 and a contoured contact plate 322 (such as Figure 5 The first clamping plate 333 is provided with two clamping plates 331 and 332, and the two clamping plates 331 are provided with a first spring 333.

The movable blade assembly mechanism 4 also includes an in-place contact rod 44 and a first connecting plate 45.

[0041] The first linear drive 34 drives the clamping seat 32 fixedly connected thereto to slide horizontally. The clamping seat 32 is slidably connected to the first mounting frame 31 through the first slide rail 35. The resistance pressure plate 38 is used to detect whether the first pushing frame 42 in the movable blade assembly mechanism 4 has moved into place, that is, to detect whether the movable blade 13 is installed in place. The in-place resistance rod 44 is installed on the first pushing frame 42 through the first connecting plate 45, and moves synchronously with the first pushing frame 42 when it moves. When the in-place resistance rod 44 resists against the resistance pressure plate 38, it means that the movable blade 13 is installed in place.

The lateral clamping device 251 is located at both ends of the torsion spring 11. The lateral clamping device 251 is used to clamp the ends of the torsion spring 11.

The mounting plate 2532 is connected to the limiting connecting plate 2531 through the second connecting plate 2515. Through the horizontal sliding cooperation of the second sliding rod 2535, the length direction of the second sliding rod 2535 is set perpendicular to the sliding direction of the first pushing frame 42, the second spring 2534 is sleeved on the second sliding rod 2535 and the two ends of the second spring 2534 are respectively fixedly connected to the limiting connecting plate 2531 and the mounting plate 2532, the fixed limiting plate 2536 is in conflict with the mounting plate 2532, the limiting hook 2533 is installed on the mounting plate 2532, and the limiting hook 2533 is provided with a hook groove for clamping the long torsion arm 113.

[0048] The hook limiting device 253 can clamp the long torsion arm 113, and cooperate with the rotation function of the deflection device 252 to make the long torsion arm 113 tilt upward, which is convenient for the subsequent installation process of the end hook 114. In the process of the sliding plates 2513 approaching each other, the elastic force of the second spring 2534 is first used to drive the mounting plate 2532 to move into place, and the fixed limiting plate 2536 is used to limit the mounting plate 2532. When the mounting plate 2532 moves into place, the long torsion arm 113 can be hooked upward by the limiting hook 2533 installed thereon, which is convenient for the insertion and installation of the movable blade 13 and the assembly process of the end hook 114 and the movable blade 13. When the spring coil 111 needs to be installed into the card slot 123, the connection between the deflection device 252 and the spring coil 111 needs to be released, that is, the sliding plate 2513 retreats, and the connection between the limiting hook 2533 and the long torsion arm 113 is maintained by the elastic force of the second spring 2534.

[0049] The hook clamping assembly 26 includes a fourth mounting frame 261, a fourth linear drive 262, a transmission plate 263, a second lifting plate 264, a transmission rod 265 and a third spring 266. The fourth mounting frame 261 is vertically arranged on the lifting mounting frame 231, the fourth linear drive 262 is vertically fixedly installed on the lifting mounting frame 231, the second lifting plate 264 and the transmission plate 263 are both horizontally arranged in the fourth mounting frame 261, the second lifting plate 264 and the transmission plate 263 are both slidably arranged with the fourth mounting frame 261 in the vertical direction, the output end of the fourth linear drive 262 is fixedly connected to the top of the second lifting plate 264, the second lifting plate 264 and the transmission plate 26 3 are elastically connected by a third spring 266, the transmission plate 263 is located just below the second lifting plate 264, and clamping blocks 2631 for clamping the long torsion arm 113 are provided at both ends of the transmission plate 263. The transmission plate 263 and the clamping block 2631 are elastically connected by a horizontally arranged elastic connecting rod 2632. A limit sliding track is vertically provided on the side wall of the fourth mounting frame 261, and a transmission rod 265 is horizontally fixedly installed on the second lifting plate 264. The length direction of the transmission rod 265 is consistent with the sliding direction of the first pushing frame 42, and the end of the transmission rod 265 is slidably matched with the limit sliding track, and the limit sliding track is provided with a vertical slide groove 267 and a Z-shaped slide groove 268 from top to bottom.

[0050] When the hook clamping assembly 26 is working, the second lifting plate 264 is driven to descend through the output of the fourth linear drive 262. After descending a certain distance, the second lifting plate 264 drives the transmission plate 263 to contact the end hook 114, and the connection between the long torsion arm 113 and the end hook 114 is clamped by the clamping block 2631, and the second lifting plate 264 is continued to be driven to descend. At this time, the third spring 266 is compressed, and the transmission rod 265 moves from the vertical slide groove 267 to the Z-shaped slide groove 268, thereby achieving the effect of driving the second lifting plate 264 to swing slightly in the horizontal direction. This process can accurately insert the end hook 114 into the mounting hole 131, and the end hook 114 is pressed into the mounting hole 131 by the elastic force of the third spring 266 to complete the assembly process. The elastic connecting rod 2632 is used to provide an elastic connection for the subsequent swinging process after the end hook 114 is clamped with the mounting hole 131.

[0051] The clamping assembly 24 includes a third linear drive 241, a first lifting plate 242 and an arc-shaped clamping block 243. The third linear drive 241 is vertically fixedly mounted on the lifting mounting frame 231, and the first lifting plate 242 is horizontally arranged (such as Figure 7As shown in the figure, the first lifting plate 242 and the lifting mounting frame 231 slide in cooperation in the vertical direction, the output end of the third linear drive 241 is fixedly connected to the first lifting plate 242, two arc-shaped clamping blocks 243 are provided, and the two arc-shaped clamping blocks 243 are respectively fixedly mounted at both ends of the first lifting plate 242, and the arc-shaped slide groove of the arc-shaped clamping block 243 matches the outer side wall of the spring coil 111.

[0052] When the clamping assembly 24 is working, the third linear drive 241 outputs to press the first lifting plate 242 downward, and the first lifting plate 242 contacts the spring coil 111 through the arc-shaped clamping blocks 243 installed at both ends, forcing the spring coil 111 to be pressed into the slot 123 of the spring seat 121, thereby realizing the installation process of the spring coil 111 and maintaining the spring coil 111 in a tight state during the installation process of the end hook 114, and releasing it after the installation is completed.

[0053] The movable blade assembly mechanism 4 further includes a second linear drive 46 and a clamping drive 47. The second linear drive 46 is fixedly mounted on the second mounting frame 41 (eg, Fig.11 As shown), the output end of the second linear drive 46 is transmission-connected to the first pushing frame 42, the clamping drive 47 is vertically fixedly installed on the top of the first pushing frame 42, the two output ends of the clamping drive 47 are respectively fixedly connected to the two blade clamping plates 43, and the first pushing frame 42 is provided with a slide groove for the blade clamping plate 43 to slide.

[0054] The output of the second linear driver 46 drives the first pushing frame 42 to move horizontally, and the output of the clamping driver 47 drives the blade clamping plate 43 to achieve the clamping function of the central transmission seat 132.

[0055] Working principle of the present invention:

[0056] The stationary blade 12 is loaded into the clamping mechanism 3 by the stationary blade loading manipulator, and the output of the first linear drive 34 drives the clamping seat 32 to move horizontally, and the stationary blade 12 located between the clamping seat 32 and the fixed seat 33 is gradually clamped by the sliding of the clamping seat 32. The output of the second linear drive 46 drives the first push rack 42 to move horizontally, and drives the blade clamping plate 43 installed thereon to move synchronously. After the dynamic blade 13 is clamped, the first push rack 42 continues to push the first push rack 42 to the top of the stationary blade 12, and the inclined chamfer set on the pressing contact seat 331 is pressed vertically downward, so that the first spring 333 is compressed, and the top of the contact seat 331 is compressed to be flush with the top of the stationary blade 12. When the in-place contact rod 44 contacts the contact pressure plate 38, it means that the dynamic blade 13 is installed in place.

[0057] After the torsion spring assembly mechanism 2 takes the material, it drives the torsion spring 11 to be transferred to the top of the assembly station (the position where the torsion spring 11 is installed) through the horizontal drive component 22 and the first lifting drive component 23. The output of the first rotary driver 2511 drives the bidirectional threaded rod 2512 to rotate, thereby driving two sliding plates 2513 threadedly matched with the bidirectional threaded rod 2512 to move closer to each other. The sliding plate 2513 inserts the end of the second rotating shaft 2524 installed thereon into the spring coil 111. When rotating, the second rotating shaft 2524 can drive the entire torsion spring 11 to deflect synchronously. The output of the second rotary driver 2521 drives the first rotating shaft 2522 to rotate. The first rotating shaft 2522 can drive the synchronous wheel 2523 to rotate through the cooperation of the transmission groove and the transmission block set thereon, and the synchronous wheel 2523 drives the second rotating shaft 2524 to rotate.

[0058] The hook limiting device 253 can clamp the long torsion arm 113, and cooperate with the rotation function of the deflection device 252 to make the long torsion arm 113 tilt upward. When the sliding plates 2513 approach each other, the elastic force of the second spring 2534 is first used to drive the mounting plate 2532 to move into place. The fixed limiting plate 2536 is used to limit the mounting plate 2532. When the mounting plate 2532 moves into place, the long torsion arm 113 can be hooked upward by the limiting hook 2533 installed thereon. When the spring coil 111 needs to be installed in the slot 123, the sliding plate 2513 retreats, and the connection between the limiting hook 2533 and the long torsion arm 113 is maintained by the elastic force of the second spring 2534. The third linear drive 241 outputs to press the first lifting plate 242 downward, and the first lifting plate 242 contacts the spring coil 111 through the arc-shaped pressing blocks 243 installed at both ends, forcing the spring coil 111 to be pressed into the slot 123 of the spring seat 121 .

[0059] The output of the fourth linear drive 262 drives the second lifting plate 264 to descend. After descending a certain distance, the second lifting plate 264 drives the transmission plate 263 to contact the end hook 114, and clamps the connection between the long torsion arm 113 and the end hook 114 through the clamping block 2631, and continues to drive the second lifting plate 264 to descend. At this time, the third spring 266 is compressed, and the transmission rod 265 moves from the vertical slide groove 267 to the Z-shaped slide groove 268, thereby achieving the effect of driving the second lifting plate 264 to swing slightly in the horizontal direction. This process can accurately insert the end hook 114 into the mounting hole 131, and the end hook 114 is pressed into the mounting hole 131 by the elastic force of the third spring 266.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
