Description

Technical Field

[0001] The utility model relates to the technical field of flexible strip lights, and more specifically to a strip light clamping mechanism. Background Art

[0002] The flexible strip light includes a main strip light, a plurality of sub-strip lights and a plurality of lamp heads. When the flexible strip light is straightened, the plurality of sub-strip lights are arranged perpendicular to the main strip light and distributed along the length direction of the main strip light, and one lamp head is connected in series to each sub-strip light. Among them, two main wires are arranged in the main strip light, and two sub-wires are also arranged in the sub-strip light. The lamp head is connected in series to the two sub-wires. During production, it is necessary to first break the skin of the main strip light to expose the main wires, then connect the two sub-wires of the sub-strip light to the two main wires of the main strip light respectively, and then wrap them, which is relatively troublesome in production. Compared with the above flexible strip light, a new type of flexible strip light structure can significantly improve production efficiency, and its specific structure is as follows: Two wires are arranged in the strip light, and a plurality of lamp heads are connected in series to the two wires. The left and right parts of the strip light where the lamp heads are located are pulled out and bent, which is equivalent to the above sub-strip light, and the strip light in the other unbent part is equivalent to the above main strip light, and then the led-out sub-strip light is fixed with a sleeve. Specifically, the strip light bends backward around a winding post in the front-rear direction, then bends to the right and then to the left, and then bends backward around the second winding post. In this way, a U-shaped main strip light is formed on the winding post, and the sub-strip light is also U-shaped and connected to two sections of the main strip light and located between the two winding posts. When using the sleeve, a plastic sleeve is directly put on the sub-strip light between the two winding posts. However, the sub-strip light between the two winding posts is in two sections, and the relatively large distance between the two sections of the sub-strip light makes it difficult to put on the sleeve. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a strip light clamping mechanism to solve the technical problem that the relatively large distance between two sections of the sub-strip light after winding in the prior art makes it difficult to put on the sleeve.

[0004] To solve the above technical problem, the utility model provides a strip light clamping mechanism, which includes a base, a driving component, a wire clamping component and a plurality of limiting posts. The driving component is connected to the base. The plurality of limiting posts are distributed on the base at intervals and are driven by the driving component to intermittently move along their distribution direction. The strip light is fixed on the plurality of limiting posts. There are two sections of strip lights to be clamped between every two adjacent limiting posts. The wire clamping component includes a driving member and two vertically arranged clamping plates. The clamping plates are parallel to the strip lights to be clamped. The two clamping plates are distributed along the direction parallel to the moving direction of the limiting posts. The driving member is connected to the base and drives the two clamping plates to reciprocate vertically and move towards each other. After the driving component drives the limiting posts to intermittently move each time, the two sections of strip lights to be clamped are located above the two clamping plates.

[0005] After adopting the above structure, a lamp strip clamping mechanism of the utility model has the following advantages: Two sections of lamp strips to be clamped are arranged between every two limit posts. The driving member drives two clamping plates to rise, so that the lamp strips to be clamped are located between the two clamping plates. Then the driving member drives the two clamping plates to move towards each other to clamp the lamp strips to be clamped. After clamping, the driving member drives the two clamping plates to move away from each other and reset downward. As the driving assembly drives the limit posts to move, two new lamp strips to be clamped are moved above the two clamping plates. By circulating the above process, the clamping of the lamp strips can be completed to reduce the distance between two sub-lamp strips, which is convenient for sleeving, so as to produce a new type of leather wire lamp.

[0006] As an improvement, a wire-straightening assembly is connected to the base platform. The wire-straightening assembly includes a first motor, a first cylinder, two clamping arms distributed vertically, and two first wire-straightening plates. The first motor is connected to the base platform and drives the first cylinder to reciprocate along the length direction of the lamp strip to be clamped. The first cylinder is connected to the two clamping arms and drives the two clamping arms to reciprocate towards each other. Each clamping arm is connected with a first wire-straightening plate. The two first wire-straightening plates are distributed vertically. On each first wire-straightening plate and on the end face facing the other first wire-straightening plate, a first groove is provided. Each first groove penetrates through both ends of the first wire-straightening plate along the direction parallel to the lamp strip to be clamped. The size of the first groove matches the size of one section of the lamp strip to be clamped. After the driving assembly drives the limit posts to move intermittently each time, one section of the lamp strip to be clamped is located between the two first grooves. With this structure, before the lamp strip to be clamped is clamped by the two clamping plates, the first cylinder first drives the two first wire-straightening plates to move towards each other so that one section of the lamp strip to be clamped is located in the two first grooves. Then the first motor drives the first cylinder and the two first wire-straightening plates to move to straighten the section of the lamp strip to be clamped, which is convenient for subsequent sleeving operation.

[0007] As an improvement, each first wire-straightening plate is provided with a first long hole vertically. The fixing bolt passes through the first long hole and is threadedly connected with the clamping arm. With this structure, the height of the first wire-straightening plate is adjusted through the first long hole to match the height of the lamp strip to be clamped. After the first cylinder drives the first wire-straightening plate to move, the lamp strip to be clamped is exactly in the first groove without vertical offset.

[0008] As an improvement, the wire-straightening assembly further includes a second wire-straightening plate. The clamping arm located above is connected with the second wire-straightening plate. The clamping arm and the second wire-straightening plate are arranged in sequence along the moving direction of the limit posts. The bottom end of the second wire-straightening plate is provided with a second groove. The second groove penetrates through both ends of the second wire-straightening plate along the direction parallel to the lamp strip to be clamped. The size of the second groove matches the size of two sections of the lamp strip to be clamped. After the driving assembly drives the limit posts to move intermittently each time, two sections of the lamp strip to be clamped are located below the second groove, and the second groove and the two clamping plates correspond to the same two sections of the lamp strip to be clamped. With this structure, the second wire-straightening plate is connected with the clamping arm located above and moves up and down synchronously with the first wire-straightening plate located above. Before the two clamping plates clamp the lamp strip to be clamped, the second groove pre-tightens and straightens the two sections of the lamp strip to be clamped first.

[0009] As an improvement, the wire-pulling assembly also includes a connecting arm, which includes a first straight portion and a second straight portion. One end of the first straight portion is connected to the clamping arm located above, and the other end of the first straight portion extends in the moving direction of the limiting column and is connected to one end of the second straight portion. The second straight portion is perpendicular to the first straight portion, and the other end of the second straight portion is connected to the second wire-pulling plate.

[0010] As an improvement, a second long hole arranged along the length direction of the first straight portion is provided on the first straight portion, and a fixing bolt passes through the second long hole and is threadedly connected to the clamping arm; a third long hole arranged along the length direction of the second straight portion is provided on the second straight portion, and a fixing bolt passes through the third long hole and is threadedly connected to the second straightening plate; with this structure, the position of the connecting arm is adjusted through the second long hole to ensure that the second groove can correspond to the same two sections of the light strip to be clamped with the two clamping plates, and the position of the second straightening plate is adjusted through the third long hole so that the second groove can pre-tighten and straighten the entire sections of the two light strips to be clamped as much as possible.

[0011] As an improvement, the driving assembly includes a second motor, a chain and two sprockets, the two sprockets are rotatably connected to the top of the base, the second motor is connected to the base and drives one of the sprockets to rotate, the chain is wrapped around the two sprockets, each link of the chain is connected to a connecting block on the outside, each connecting block is connected to two spaced-apart limit columns, and several limit columns are distributed at circumferential intervals; with this structure, the annular closed structure formed by the chain makes the connecting blocks and limit columns connected to the chain links also form an annular structure, and as the chain moves, the limit columns can be recycled and reused.

[0012] As an improvement, a positioning block located between the two sprockets is connected to the base, and a positioning groove is provided on the positioning block for a part of the connecting block to pass through, and several connecting blocks located in the positioning groove are slidably connected to the positioning block. With this structure, the positioning block and the positioning groove play a positioning and guiding role for the connecting block between the two sprockets, thereby preventing the position deviation of the connecting block caused by chain loosening.

Detailed implementation manners

[0019] The following will make a detailed description of a lamp strip clamping mechanism of the present utility model with reference to the accompanying drawings.

[0020] As Figures 1 to 5 shown, a lamp strip clamping mechanism includes a base 1, a drive assembly 2, a wire clamping assembly 3 and a plurality of limit posts 4. The drive assembly 2 is connected to the base 1, and the plurality of limit posts 4 are arranged at intervals on the base 1 and are driven by the drive assembly 2 to intermittently move along their distribution direction; as Figure 3 and Figure 4 shown, the drive assembly 2 includes a second motor, a chain 22 and two sprockets 23. The two sprockets 23 are rotatably connected to the top of the base 1. The second motor is connected to the base 1 and drives one of the sprockets 23 to rotate. The chain 22 is wound around the two sprockets 23. A connecting block 11 is connected to the outside of each link of the chain 22, so that the respective connecting blocks 11 are circumferentially distributed in a ring along the chain 22. Each connecting block 11 is connected to two spaced-apart limit posts 4. The plurality of limit posts 4 are circumferentially spaced apart, that is, the plurality of limit posts 4 are also circumferentially and annularly spaced apart along the chain 22; and the chain 22 has a straight portion and an arc portion. Correspondingly, the distribution of the limit posts 4 at different positions of the chain 22 is also divided into straight-line spaced distribution and arc-separated distribution. The moving direction of the limit posts 4 in the straight-line spaced distribution is also a straight line direction, and the moving direction of the limit posts 4 in the arc-separated distribution is also an arc direction. And the clamping operation is performed at the limit posts 4 in the straight-line spaced distribution. That is to say, the moving direction of the limit posts 4 at the clamping operation position is a straight line direction, which is the front-back direction in this embodiment.

[0021] The light strip is fixed on several limiting posts 4. There are two sections of light strip to be clamped between every two adjacent limiting posts 4. Since the light strip itself is deformable and can maintain a fixed shape when not under external force, the light strip can be fixed to the limiting posts 4 by winding around the limiting posts 4. In order to further improve the fixing stability of the light strip and the limiting posts 4, a limiting structure such as a limiting groove can also be provided on the limiting posts 4 to further fix the light strip. The specific fixing form of the light strip on the limiting posts 4 is: the light strip bends backward along the front-back direction around a limiting post 4, then bends to the right and then to the left, and then bends backward around the second limiting post 4, so that two sections of light strip to be clamped are formed between the two limiting posts 4.

[0022] As Figure 1 and Figure 2 shown, the wire clamping assembly 3 includes a driving member 31 and two vertically arranged clamping plates 32. The clamping plates 32 are parallel to the light strip to be clamped. The two clamping plates 32 are distributed along the moving direction of the limiting posts 4, that is, the clamping plates 32 are distributed along the front-back direction. The driving member 31 is connected to the base 1 and drives the two clamping plates 32 to move reciprocally in the vertical direction and move reciprocally towards each other. The so-called moving reciprocally towards each other means that the two clamping plates 32 move towards each other and move away from each other, that is, one of the two clamping plates 32 moves forward and the other moves backward to move away from or close to each other; it should be noted that since the length direction of the light strip to be clamped is not uniform, the clamping plates 32 being parallel to the light strip to be clamped means being parallel to the ideal direction of the light strip to be clamped, and the ideal direction of the light strip to be clamped is the left-right direction, that is to say, the clamping plates 32 are arranged along the left-right direction itself. After the driving assembly 2 drives the limiting posts 4 to move intermittently each time, the two sections of light strip to be clamped are located above the two clamping plates 32. The driving member 31 is composed of a cylinder for driving the clamping plate 32 to move up and down and a cylinder for driving the clamping plate 32 to move towards each other; each time the driving assembly 2 drives the connecting block 11 and the limiting posts 4 to move, the moving distance is the center distance between the two limiting posts 4, and the two sections of light strip to be clamped located on the front side can be moved backward to above the middle of the two clamping plates 32. As Figure 3 and Figure 4 shown, a positioning block 12 is connected to the base 1 between the two sprockets 23. A positioning groove 13 for a part of the connecting block 11 to pass through is provided on the positioning block 12. Several connecting blocks 11 located in the positioning groove 13 are slidably connected to the positioning block 12. That is to say, for the connecting blocks 11 distributed at intervals along a straight line, a part of the connecting block 11 slides back and forth in the positioning groove 13, thereby restricting the position offset of the connecting block 11 in the left-right direction.

[0023] In addition, as Figure 3 and Figure 4As shown, a wire-straightening assembly 5 is connected to the base 1. The wire-straightening assembly 5 includes a first motor 51, a first cylinder 52, two clamping arms 53 distributed vertically, two first wire-straightening plates 54, a second wire-straightening plate 55, and a connecting arm 56. The first motor 51 is connected to the base 1 and drives the first cylinder 52 to reciprocate along the length direction of the strip to be clamped. Specifically, the first motor 51 realizes the linear drive of the first cylinder 52 through a lead screw guide rail. The length directions of the two clamping arms 53 are both arranged in the left-right direction. The first cylinder 52 is connected to the two clamping arms 53 and drives the two clamping arms 53 to reciprocate towards each other, that is, the two clamping arms 53 approach or move away from each other, one upward and one downward. A first wire-straightening plate 54 is connected to each clamping arm 53. Specifically, the first wire-straightening plate 54 is connected to the left end face of the clamping arm 53. The two first wire-straightening plates 54 are distributed vertically, and as Figure 5 shown, a first long hole 7 arranged vertically is provided on each first wire-straightening plate 54, and a fixing bolt is threadedly connected to the clamping arm 53 through the first long hole 7. A first groove 6 is provided on the end face of each first wire-straightening plate 54 facing the other first wire-straightening plate 54. Each first groove 6 penetrates through both ends of the first wire-straightening plate 54 along the direction parallel to the strip to be clamped, that is, the left-right direction. The size of the first groove 6 matches the size of a section of the strip to be clamped. Specifically, when the two first wire-straightening plates 54 are in contact with each other, a section of the strip to be clamped is exactly accommodated in the two first grooves 6. After the driving assembly 2 drives the limit post 4 to move intermittently each time, a section of the strip to be clamped is located between the two first grooves 6. The clamping arms 53 and the first wire-straightening plates 54 are located on the front side of the clamping plate 32.

[0024] As Figure 2 and Figure 4 shown, the clamping arm 53 located above is connected to the second wire-straightening plate 55. Specifically, the connecting arm 56 includes a first straight portion 561 and a second straight portion 562. One end of the first straight portion 561 is connected to the clamping arm 53 located above. The other end of the first straight portion 561 extends in the moving direction of the limit post 4 and is connected to one end of the second straight portion 562. The second straight portion 562 is perpendicular to the first straight portion 561. The other end of the second straight portion 562 is connected to the second wire-straightening plate 55. That is, the first straight portion 561 is arranged in the front-back direction, the second straight portion 562 is arranged in the left-right direction, and the second wire-straightening plate 55 is connected to the bottom end of the other end of the second straight portion 562. A second long hole 9 arranged along the length direction of the first straight portion 561 is provided on the first straight portion 561, and a fixing bolt passes through the second long hole 9 and is threadedly connected to the clamping arm 53. A third long hole 10 arranged along the length direction of the second straight portion 562 is provided on the second straight portion 562, and a fixing bolt passes through the third long hole 10 and is threadedly connected to the second wire-straightening plate 55.

[0025] As Figure 2 and Figure 4As shown, the clamping arms 53 and the second wire-straightening plate 55 are distributed in sequence along the moving direction of the limiting post 4. That is to say, the second wire-straightening plate 55 is located at the rear side of the clamping arms 53. A second groove 8 is provided at the bottom end of the second wire-straightening plate 55. The second groove 8 penetrates through both ends of the second wire-straightening plate 55 along the direction parallel to the light strip to be clamped, that is, the left-right direction. The size of the second groove 8 matches the sizes of the two sections of the light strip to be clamped. Since the two sections of the light strip to be clamped are separated from each other at this time, the size of the second groove 8 is based on the two separated sections of the light strip to be clamped and can accommodate the two sections of the light strip to be clamped. After the driving assembly 2 drives the limiting post 4 to move intermittently each time, the two sections of the light strip to be clamped are located below the second groove 8, and the second groove 8 and the two clamping plates 32 correspond to the same two sections of the light strip to be clamped.

[0026] One of the light strips to be clamped, in this embodiment, the front section is first wire-straightened by the two first wire-straightening plates 54, and then as the limiting post 4 moves, the two sections of the light strip to be clamped are wire-straightened by the second wire-straightening plate 55. After that, the driving member 31 drives the two clamping plates 32 to rise, so that the light strip to be clamped is located between the two clamping plates 32. Then the driving member 31 drives the two clamping plates 32 to move towards each other to clamp the light strip to be clamped. After clamping, the driving member 31 drives the two clamping plates 32 to move away from each other and reset downward. As the driving assembly 2 drives the limiting post 4 to move, two new sections of the light strip to be clamped are moved above the two clamping plates 32. By circulating the above process, the light strip can be clamped, thus completing the production of the new leather wire lamp.

All other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.
