Description

Technical Field

[0001] This utility model belongs to the technical field of LED lamp assembly mechanism, specifically relating to a clamping device. Background Technology

[0002] In actual production, with the rapid development of LED lighting technology, automated assembly equipment is increasingly widely used in LED lamp production. In the traditional LED lamp assembly process, the assembly of wires and plugs generally suffers from the following problems: the wire clamping mechanism is mostly pneumatic or hydraulically driven, resulting in complex equipment structure, high maintenance costs, and unstable clamping force of existing mechanical grippers, which can easily cause damage to the wire surface or poor contact; the opening and closing control of the clamping mechanism requires additional sensors and actuators, increasing system complexity; especially for the assembly of micro LED lamps, conventional equipment is difficult to achieve high-precision and flexible clamping operations, and is prone to positioning deviation problems caused by mechanical fatigue after long-term operation. Therefore, there is an urgent need to develop an automated assembly device with a compact structure, simple control, and adaptive clamping function. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This invention provides a clamping device that aims to solve the problems of complex clamping of LED light wires, unstable clamping force, and high cost.

[0005] (2) Technical solution

[0006] This utility model provides a clamping device, including a frame, on which a rotating disk and a fixed disk are coaxially arranged, and a driving mechanism for driving the rotating disk to rotate. The edge of the rotating disk is provided with a plurality of clamping mechanisms for clamping or releasing wires.

[0007] The fixed disk has a recessed portion. The clamping mechanism includes a fixed frame, a sliding member slidably connected to the fixed frame, and clamping arm assemblies respectively disposed on both sides of the sliding member and movably connected to the sliding member. The clamping mechanism also includes an elastic element that keeps the sliding member moving towards the fixed disk. When the driving mechanism drives the rotating disk to rotate, the sliding member in the clamping assembly abuts against or moves away from the recessed portion and slides relative to the recessed portion under the elastic force of the elastic element. The relative sliding of the sliding member drives the opening and closing of the two clamping arm assemblies to clamp or release the wire.

[0008] Furthermore, the clamping arm assembly includes a clamping member one and a clamping member two. The clamping member one includes a connecting part one and a clamping part one disposed at the end of the connecting part one. The clamping member two includes a connecting part two and a clamping part two disposed at the end of the connecting part two.

[0009] Furthermore, the first connecting part and the second connecting part are gear structures.

[0010] Furthermore, the sliding member includes a movable member and a contact member disposed on the movable member. The contact member abuts against or moves away from the recessed portion under the action of the driving mechanism, and the movable member moves under the action of the contact member and the elastic member.

[0011] Furthermore, the moving part is a rack and pinion structure, and it is engaged with the first connecting part and the second connecting part, respectively.

[0012] Furthermore, the second clamping part is provided with a groove that is adapted to the first clamping part.

[0013] Furthermore, the clamping part two is also provided with toothed grooves adapted to the wire.

[0014] Furthermore, a spring piece is provided on the side of the clamping part two away from the tooth groove, and the spring piece is connected to a shaft pin, the other end of which passes through the clamping part two and extends into the groove.

[0015] Furthermore, the fixing frame is provided with a clamping component one on the side away from the sliding member. The clamping component one includes a clamping jaw one and a clamping jaw two that can be opened and closed with each other. Both the clamping jaw one and the clamping jaw two are provided with interlocking rotating teeth.

[0016] Furthermore, it also includes a lifting member disposed on a rotating disk, at least one of the first and second grippers having a rotating part, and the output shaft of the lifting member abutting against the rotating part to control the opening and closing of the first clamping assembly.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] By employing the cooperation between the recessed part and the clamping mechanism on the rotating disk, the clamping action is automatically controlled through mechanical contact, eliminating the need for additional sensors and actuators. The rotational motion of the rotating disk is converted into the action of clamping and releasing the wire. The cooperation between the various components realizes the transmission and conversion of force, effectively achieving the function of clamping and releasing the wire. Moreover, the structure is relatively simple, easy to manufacture and maintain, and reduces production costs. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] like Figure 1-11As shown, this utility model discloses a clamping device, including a frame 5. The frame 5 is provided with a rotating disk 1 and a fixed disk 2 coaxially arranged, and a driving mechanism 9 for driving the rotating disk 1 to rotate. The edge of the rotating disk 1 is provided with several clamping mechanisms 3 for clamping or releasing the wire 41. In the assembly process of the LED lamp 4, the LED lamp 4 includes a wire 41, a light strip 42 and a rubber plug 43. The light strip 42 is inserted into the rubber plug 43. It is necessary to first insert the wire 41 into the rubber plug 43 of the LED lamp 4, then bend the wire 41, and then insert the light strip 42 into the rubber plug 43 to assemble the LED lamp 4. When inserting the light strip 42, in order to prevent the wire 41 from detaching from the rubber plug 43, there is an urgent need for a device with a simple structure and low cost to clamp the wire 41.

[0033] like Figure 2-3 As shown, the fixed disk 2 has a recessed portion 21. The clamping mechanism 3 includes a fixed frame 34, a sliding member 32 slidably connected to the fixed frame 34, and clamping arm assemblies 33 respectively disposed on both sides of the sliding member 32 and movably connected to the sliding member 32. The clamping mechanism 3 also includes an elastic element 31 that keeps the sliding member 32 moving towards the fixed disk 2. In use, when the driving mechanism 9 drives the rotating disk 1 to rotate, when the sliding member 32 in the clamping mechanism 3 moves away from the recessed portion 21 without contacting it, the sliding member 32 moves forward under the action of the fixed disk 2. The sliding member 32 drives the clamping arm assemblies 33 to rotate, thereby releasing the wire 41. At this time, the elastic element 31 is compressed. When the sliding member 32 abuts against the recessed portion 21, the elastic element 31 is compressed. When the sliding member 32 reaches the recess 21 and does not abut against the fixing frame 34, the sliding member 32 returns to its original position under the elastic force of the elastic member 31, thereby driving the clamping arm assembly 33 to move closer and clamp the wire 41. By sliding relative to each other under the elastic force of the elastic member 31, the relative sliding of the sliding member 32 drives the opening and closing of the two clamping arm assemblies 33 to clamp or release the wire 41. At the same time, through the cooperation of the rotating disk 1, the sliding member 32, the clamping arm assembly 33 and the elastic member 31, the rotational motion of the rotating disk 1 is converted into the action of clamping and releasing the wire 41. The cooperation between the components realizes the transmission and conversion of force, which can effectively realize the clamping and releasing function of the wire 41. Moreover, the structure is relatively simple, easy to manufacture and maintain, and has a low cost.

[0034] Specifically, such as Figure 4-6As shown, the clamping arm assembly 33 includes a first clamping member 331 and a second clamping member 332. The first clamping member 331 includes a first connecting portion 333 and a first clamping portion 334 disposed at the end of the first connecting portion 333. The second clamping member 332 includes a second connecting portion 335 and a second clamping portion 336 disposed at the end of the second connecting portion 335. The first clamping member 331 and the second clamping member 332 move closer to each other or open apart under the action of the sliding member 32, thereby realizing the clamping and release of the wire 41. This symmetrical structural design can ensure the uniform distribution of clamping force, avoid the wire 41 being damaged by uneven force during the clamping process, and also help improve the stability and reliability of clamping.

[0035] Furthermore, the first connecting part 333 and the second connecting part 335 are gear structures.

[0036] Furthermore, in order to reduce the wear of the fixed disk 2 on the sliding member 32, the sliding member 32 includes a moving member 322 and a contact member 321 disposed on the moving member 322. The contact member 321 abuts against or moves away from the recessed portion 21 under the action of the driving mechanism 9, and the moving member 322 moves under the action of the contact member 321 and the elastic member 31.

[0037] Furthermore, the moving part 322 is a rack and pinion structure, and is meshed with the first connecting part 333 and the second connecting part 335 respectively. The meshing connection of rack and pinion can achieve a precise transmission ratio and stable motion transmission, making the clamping and releasing actions more accurate and reliable.

[0038] Furthermore, in order to enhance the clamping effect on the wire 41, the second clamping part 336 is provided with a groove 3361 that is adapted to the first clamping part 334. When the first clamping part 334 and the second clamping part 336 approach each other, the wire 41 can be firmly clamped between the groove 3361 and the first clamping part 334, preventing the wire 41 from sliding or falling off during the clamping process, which is beneficial to improving the yield rate in the production process.

[0039] Furthermore, in order to achieve precise positioning and clamping of the wire 41, the clamping part 2 336 is also provided with a toothed groove 337 adapted to the wire 41. The shape and structure of the toothed groove 337 can increase the contact area and friction between the wire 41 and the clamping part, making the clamping more secure. When the clamping part 1 334 and the clamping part 2 336 approach each other to clamp the wire 41, the toothed groove 337 can be embedded in the surface of the wire 41 or closely fit the wire 41, thereby providing greater clamping force and ensuring that the wire 41 will not loosen during subsequent processing or operation.

[0040] Specifically, such as Figure 6 As shown, the fixed frame 34 is provided with a sliding groove 341, and the sliding member 32 is connected with a slider 323 adapted to the sliding groove 341, which realizes the guidance and limitation of the sliding member 32, ensuring that the sliding member 32 moves along a predetermined trajectory. At the same time, through the cooperation of the sliding groove 341 and the slider 323, the shaking and deviation of the sliding member 32 during the movement are reduced, and the stability of the movement is improved. This helps to improve the clamping accuracy and reliability of the clamping mechanism 3, ensuring that the clamping mechanism 3 can accurately complete the action when clamping and releasing the wire 41.

[0041] Preferably, a spring piece 338 is provided on the side of the clamping part 336 away from the toothed groove 337. The spring piece 338 is connected to a shaft pin 339. The other end of the shaft pin 339 passes through the clamping part 336 and extends into the groove 3361. The spring piece 338 is elastic and can provide elastic clamping force to the clamping part 336, so that the clamping part 336 can automatically adapt to the shape and size of the wire 41 when clamping it, ensuring the stability and reliability of clamping. There is no need to replace different clamping parts for wires 41 of different specifications, which reduces production and maintenance costs. At the same time, by setting the cooperation between the spring piece 338 and the shaft pin 339, the problem of deformation or damage to the wire 41 due to excessive clamping force is avoided, improving the product yield. This structural design is simple, reduces the frequency of maintenance and replacement of parts, and lowers production costs.

[0042] Specifically, such as Figure 6-7 As shown, the fixing frame 34 is further provided with a clamping assembly 35 on the side away from the sliding member 32. The clamping assembly 35 includes a first clamping jaw 351 and a second clamping jaw 352 that can be opened and closed. Both the first clamping jaw 351 and the second clamping jaw 352 are provided with interlocking rotating teeth 353. During use, the clamping assembly 35 is used to clamp the rubber stopper 43. By the engagement and disengagement of the rotating teeth 353, the opening and closing action of the clamping assembly 35 can be precisely controlled to achieve the clamping and release of the rubber stopper 43.

[0043] Furthermore, it also includes a lifting member 6 disposed on the rotating disk 1. At least one of the first gripper 351 and the second gripper 352 is provided with a rotating part 354. The output shaft of the lifting member 6 abuts against the rotating part 354 to control the opening and closing of the clamping assembly 35. In use, when it is necessary to clamp or release the rubber stopper 43, the lifting member 6 is provided at the unloading or loading point. The operation of the lifting member 6 causes the output shaft to abut against the rotating part 354 and push the clamping assembly 35. The first gripper 351 and the second gripper 352 of the clamping assembly 35 rotate away from each other to release the rubber stopper 43.

[0044] Furthermore, in order to clamp and feed the rubber stopper 43, the clamping assembly 35 further includes an elastic element 355 that causes the rotating part 354 to maintain a tendency to move towards the fixed disk 2. When the clamping assembly 35 moves away from the lifting member 6, the rotating part 354 returns to its original position under the action of the elastic element 355, causing the jaw 351 and the jaw 352 to move closer to each other to clamp the rubber stopper 43.

[0045] Specifically, such as Figure 8 As shown, the frame 5 is also equipped with a feeding mechanism 7. The feeding mechanism 7 includes a drive component 71 and a clamping component 2 72 connected to the output shaft of the drive component 71. The clamping component 2 72 is used to clamp the light strip 42. The drive component 71 drives the clamping component 2 72 to move and insert the light strip 42 into the rubber plug 43 of the LED light 4. Automated feeding greatly reduces the time and labor intensity of manual feeding, improves production efficiency, meets the needs of large-scale production, and enhances the enterprise's production capacity and market competitiveness. The feeding mechanism 7 can accurately control the insertion position and movement of the light strip 42, ensure the accurate assembly of the light strip 42 and the rubber plug 43, reduce quality problems caused by improper assembly, and improve the product qualification rate and reliability. Workers do not need to manually feed and insert the light strip 42, but only need to monitor the operating status of the equipment, which reduces labor intensity, improves the working environment, and improves work efficiency.

[0046] Furthermore, such as Figure 1 , Figure 9-11 As shown, since pressing the light strip 42 into the rubber plug 43 requires a large pressing force, in order to prevent the rubber plug 43 from detaching from the clamping mechanism 3 under the action of the pressing force, resulting in incomplete pressing, the frame 5 is also provided with a fixing mechanism 8. The fixing mechanism 8 includes an abutment member 81. The abutment member 81 reaches the upper end face of the clamped rubber plug 43 and abuts against it under the drive of a motor or cylinder. The abutment member 81 is also provided with a clearance groove 811. The clearance groove 811 is adapted to the position of the wire 41 to fix the rubber plug 43, prevent the rubber plug 43 from falling off when pressing into the light strip 42, ensure the tight connection between the light strip 42 and the rubber plug 43, and ensure the smooth progress of the assembly process.

[0047] The following is a detailed explanation of the working principle of this utility model;

[0048] In use, when the driving mechanism 9 drives the rotating disk 1 to rotate, when the sliding member 32 in the clamping mechanism 3 moves away from the recessed portion 21 without contacting it, the sliding member 32 moves forward under the action of the fixed disk 2. The sliding member 32 drives the clamping arm assembly 33 to rotate, thereby releasing the wire 41. At this time, the elastic member 31 is compressed. When the sliding member 32 contacts the recessed portion 21, that is, when the sliding member 32 reaches the recessed portion 21 without contacting the fixed frame 34, the sliding member 32 returns to its original position under the elastic force of the elastic member 31, thereby driving the clamping arm assembly 33 to move closer, thereby clamping the wire 41. By sliding relative to each other under the elastic force of the elastic member 31, the relative sliding of the sliding member 32 drives the opening and closing of the two clamping arm assemblies 33 to achieve clamping or releasing the wire 41.

[0049] The innovation of this utility model lies in the cooperation between the recessed part and the clamping mechanism on the rotating disk. The clamping action is automatically controlled through mechanical contact, without the need for additional sensors and actuators. The rotational motion of the rotating disk is converted into the action of clamping and releasing the wire. The components cooperate with each other to realize the transmission and conversion of force, which can effectively realize the clamping and releasing function of the wire. Moreover, the structure is relatively simple, easy to manufacture and maintain, and reduces production costs.
