Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a punching and belt-pulling limiting mechanism for carrier tape production equipment. Background Technique

[0002] A carrier tape refers to a strip-shaped product applied in the field of electronic packaging. It has a specific thickness, and holes for placing electronic components and positioning holes for indexing and positioning are equidistantly distributed in its length direction.

[0003] In carrier tape production equipment, the punching and belt-pulling limiting mechanism of the carrier tape consists of a moving shaft, a moving shaft stop block, a moving shaft adjusting nut, and a moving shaft fixing nut. During the movement of the moving shaft, when it reaches the corresponding position of its stroke, the moving shaft adjusting nut collides with the moving shaft stop block and stops moving. However, the traditional moving shaft stop block is made of relatively large polyurethane material, while the adjusting nut is relatively small. After long-term impact with the moving shaft stop block, a groove in the shape of the moving shaft adjusting nut will be formed on the moving shaft stop block, resulting in a relative change in the moving shaft stroke, shortening the overall stroke, and because the moving shaft block is damaged to a certain extent, the moving shaft stroke cannot reach the required standard. Content of the Utility Model

[0004] The purpose of the utility model is to provide a punching and belt-pulling limiting mechanism for carrier tape production equipment, so as to solve the problem that the traditional moving shaft stop block is made of relatively large polyurethane material, while the adjusting nut is relatively small. After long-term impact with the moving shaft stop block, a groove in the shape of the moving shaft adjusting nut will be formed on the moving shaft stop block, resulting in a relative change in the moving shaft stroke, shortening the overall stroke, and because the moving shaft block is damaged to a certain extent, the moving shaft stroke cannot reach the required standard as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution. The punching and belt-pulling limiting mechanism for carrier tape production equipment includes a moving shaft. A fixed seat is movably connected to the surface of the moving shaft. A moving shaft stop block fixing is fixedly connected to the surface of the fixed seat. A moving shaft stop block is inserted and connected to the surface of the moving shaft stop block fixing. A moving shaft adjusting flange nut is movably connected to the surface of the moving shaft. A moving shaft fixing nut is fixedly connected to the surface of the moving shaft. A first placement groove is opened on the surface of the moving shaft stop block fixing. An elastic metal plate is fixedly connected to the surface of the first placement groove. A second placement groove is opened on the surface of the moving shaft stop block fixing. A spring damper is fixedly connected to the surface of the second placement groove. A fixing spring is sleeved on the surface of the spring damper. A gasket is fixedly connected to the surface of the fixing spring.

[0006] Preferably, the moving shaft is in the shape of a round rod, the fixed seat is in the shape of a block, the moving shaft penetrates through the fixed seat, and the moving shaft stop block is fixedly formed in a circular ring shape.

[0007] Preferably, the moving shaft stop block is embedded in the moving shaft stop block fixing, the moving shaft stop block is in a circular ring shape, and the moving shaft stop block is movably connected to the moving shaft.

[0008] Preferably, the moving shaft stop block is made of low-elastic rubber, and the moving shaft adjusting flange nut can adjust its position on the surface of the moving shaft.

[0009] Preferably, the elastic metal plate is in the shape of an arc plate, the elastic metal plate is made of elastic metal material, and the second placement grooves are distributed in two groups on the surface of the moving shaft stop block fixing.

[0010] Preferably, the spring damper is in a cylindrical shape, and both ends of the fixed spring are fixedly connected to the moving shaft stop block fixing and the gasket respectively.

[0011] Preferably, the gasket is in the shape of an arc plate, and the spring damper, the fixed spring and the gasket are all distributed in two groups on the surface of the second placement groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the movable connection between the moving shaft and the fixed seat, the fixed connection between the fixed seat and the moving shaft stop block fixing, the insertion connection between the moving shaft stop block fixing and the moving shaft stop block, the movable connection between the moving shaft and the moving shaft adjusting flange nut, and the fixed connection between the moving shaft and the moving shaft fixing nut, the overall moving shaft stop block is split into two parts, namely the moving shaft stop block fixing and the moving shaft stop block, and the material of the moving shaft stop block is changed from polyurethane to low-elastic rubber. During equipment production, when the moving shaft adjusting flange nut collides with the moving shaft stop block, its movement stroke is determined. The low-elastic rubber material has good impact and absorption performance and hardly rebounds to absorb energy, so each pulling belt stroke is relatively consistent, improving the accuracy and stability of the punching and pulling belt of the carrier tape production equipment, and reducing the noise generated during impact. By changing the size of the moving shaft adjusting flange nut to make it the same as the size of the moving shaft stop block, the stress area is increased, reducing the loss of the moving shaft stop block.

The surface fixed by the moving shaft stop block is provided with a second placement groove, which is fixedly connected to the spring damper. The spring damper is sleeved with the fixed spring, and the fixed spring is fixedly connected to the gasket. After the moving shaft stop block is embedded and fixed, the first placement groove and the gasket will abut against the moving shaft stop block, thereby making the connection between the moving shaft stop block fixing and the moving shaft stop block more firm, realizing the firm inlay of the moving shaft stop block fixing and the moving shaft stop block.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] Carrier tape production equipment punching and pulling tape limiting mechanism, including a moving shaft 1. The moving shaft 1 is used to move and drive the moving shaft adjusting flange nut 5 and the moving shaft fixing nut 6 to move, so that the moving shaft adjusting flange nut 5 impacts the moving shaft stop block 4. The surface of the moving shaft 1 is movably connected with a fixed seat 2. The fixed seat 2 is used to fix the moving shaft stop block fixing 3 and the moving shaft stop block 4. The surface of the fixed seat 2 is fixedly connected with the moving shaft stop block fixing 3. The moving shaft stop block fixing 3 is used to inlay the moving shaft stop block 4 and fix the moving shaft stop block 4 on the fixed seat 2. The surface of the moving shaft stop block fixing 3 is inserted and connected with the moving shaft stop block 4. The moving shaft stop block 4 is used to collide with the moving shaft adjusting flange nut 5, thereby determining the moving stroke of the moving shaft adjusting flange nut 5 and stopping the stroke of the moving shaft 1. The surface of the moving shaft 1 is movably connected with the moving shaft adjusting flange nut 5. The moving shaft adjusting flange nut 5 is used to impact the moving shaft stop block 4, thereby determining the moving stroke of the moving shaft adjusting flange nut 5 and stopping the stroke of the moving shaft 1. The surface of the moving shaft 1 is fixedly connected with the moving shaft fixing nut 6. The pulling tape stroke of the moving shaft 1 is determined by the relative positions of the moving shaft adjusting flange nut 5 and the moving shaft fixing nut 6. The surface of the moving shaft stop block fixing 3 is provided with a first placement groove 7. The first placement groove 7 is used to place the elastic metal plate 8. The surface of the first placement groove 7 is fixedly connected with the elastic metal plate 8. The elastic metal plate 8 is used to abut against the moving shaft stop block 4, making the inlay of the moving shaft stop block fixing 3 and the moving shaft stop block 4 more firm. The surface of the moving shaft stop block fixing 3 is provided with a second placement groove 9. The second placement groove 9 is used to place the spring damper 10, the fixing spring 11 and the gasket 12. The surface of the second placement groove 9 is fixedly connected with the spring damper 10. The spring damper 10 is used to prevent the fixing spring 11 from shaking when compressed. The fixing spring 11 is sleeved on the surface of the spring damper 10. The fixing spring 11 is used to push the gasket 12 to abut against the moving shaft stop block 4, making the inlay of the moving shaft stop block fixing 3 and the moving shaft stop block 4 more firm. The surface of the fixing spring 11 is fixedly connected with the gasket 12. The gasket 12 is used to abut against the moving shaft stop block 4, making the inlay of the moving shaft stop block fixing 3 and the moving shaft stop block 4 more firm.

[0024] Further, the moving shaft 1 is in the shape of a round rod. The moving shaft 1 is used to move and drive the moving shaft adjusting flange nut 5 and the moving shaft fixing nut 6 to move, so that the moving shaft adjusting flange nut 5 impacts the moving shaft stop block 4. The fixed seat 2 is in the shape of a block. The fixed seat 2 is used to fix the moving shaft stop block fixing 3 and the moving shaft stop block 4. The moving shaft 1 penetrates through the fixed seat 2. The moving shaft stop block fixing 3 is in the shape of a circular ring. The moving shaft stop block fixing 3 is used to inlay the moving shaft stop block 4 and fix the moving shaft stop block 4 on the fixed seat 2.

[0025] Further, the moving shaft stop block 4 is embedded in the moving shaft stop block fixture 3. The moving shaft stop block 4 is in an annular shape and is movably connected to the moving shaft 1. The moving shaft stop block 4 is used to collide with the moving shaft adjusting flange nut 5, thereby determining the movement stroke of the moving shaft adjusting flange nut 5 and stopping the stroke of the moving shaft 1.

[0026] Further, the moving shaft stop block 4 is made of a low-elastic rubber material. The moving shaft adjusting flange nut 5 can adjust its position on the surface of the moving shaft 1. The moving shaft adjusting flange nut 5 is used to impact the moving shaft stop block 4, thereby determining the movement stroke of the moving shaft adjusting flange nut 5 and stopping the stroke of the moving shaft 1. The pulling belt stroke of the moving shaft 1 is determined by the relative positions of the moving shaft adjusting flange nut 5 and the moving shaft fixing nut 6. The first placement groove 7 is used to place the elastic metal plate 8.

[0027] Further, the elastic metal plate 8 is in an arc-shaped plate form and is made of an elastic metal material. The elastic metal plate 8 is used to abut against the moving shaft stop block 4, making the embedding of the moving shaft stop block fixture 3 and the moving shaft stop block 4 more firm. The second placement grooves 9 are distributed in two groups on the surface of the moving shaft stop block fixture 3. The second placement grooves 9 are used to place the spring damper 10, the fixing spring 11, and the gasket 12.

[0028] Further, the spring damper 10 is in a cylindrical shape. The spring damper 10 is used to prevent the fixing spring 11 from shaking when it is compressed. The two ends of the fixing spring 11 are respectively fixedly connected to the moving shaft stop block fixture 3 and the gasket 12. The fixing spring 11 is used to push the gasket 12 to abut against the moving shaft stop block 4, making the embedding of the moving shaft stop block fixture 3 and the moving shaft stop block 4 more firm.

[0029] Further, the gasket 12 is in an arc-shaped plate form. The spring damper 10, the fixing spring 11, and the gasket 12 are all distributed in two groups on the surface of the second placement groove 9. The gasket 12 is used to abut against the moving shaft stop block 4, making the embedding of the moving shaft stop block fixture 3 and the moving shaft stop block 4 more firm.

[0030] Working principle: During equipment production, the movement of the moving shaft 1 drives the moving shaft adjusting flange nut 5 to collide with the moving shaft stop block 4, thereby determining its movement stroke. The moving shaft stop block 4 is made of a low-elastic rubber material, which has good impact and energy absorption performance and hardly rebounds to absorb energy. Therefore, each pulling belt stroke is relatively consistent, improving the accuracy and stability of the punching and pulling belt of the carrier tape production equipment, and reducing the noise generated during the impact. By changing the size of the moving shaft adjusting flange nut 5 to make it the same as that of the moving shaft stop block 4, the force-bearing area of the moving shaft stop block 4 is increased when the moving shaft adjusting flange nut 5 and the moving shaft stop block 4 collide, reducing the loss of the moving shaft stop block 4.

[0031] After the moving axis stop block 4 is embedded in the moving axis stop block fixture 3, both the first placement groove 7 and the fixing spring 11 will be compressed under force. The first placement groove 7 and the fixing spring 11 will rebound to generate a reverse acting force, causing the first placement groove 7 to abut against the moving axis stop block 4, and the fixing spring 11 to push the gasket 12 to abut against the moving axis stop block 4, thereby making the connection between the moving axis stop block fixture 3 and the moving axis stop block 4 more firm and achieving a firm embedding of the moving axis stop block fixture 3 and the moving axis stop block 4.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
