Fig. 1 is a schematic structural diagram of a constant pressure maintaining device with pressure feedback according to an embodiment of the present utility model, and as shown in fig. 1, the constant pressure maintaining device with pressure feedback includes a frame 1, a carrier 2, a pressing component 3, a pressure sensor 4, and a weight 5. The structure of the frame 1 may be set as needed, and is not limited herein. Further, the carrier 2 is movably arranged on the frame 1, and the pressing assembly 3 is arranged at the lower end of the carrier 2, so that the carrier 2 can be moved downwards to keep the pressure of the product. Further, a weight 5 is provided at the upper end of the carrier 2 so that pressure can be applied to the pressing member 3 by the carrier 2 by its own weight to pressurize the product by the pressing member 3.

It should be noted that, the weight block 5 in this embodiment is a weight, and the mass and the number of the weights can be set according to the need, so that the required dwell pressure meeting the standard can be set, and the dwell pressure is ensured to be constant. In addition, the weight is not easy to wear, and the consistency of the pressure maintaining pressure of each time after the constant pressure maintaining device is used for a long time is guaranteed, so that the product yield can be improved. It should be further noted that a pressure sensor 4 is provided between the carrier 2 and the pressing member 3 for monitoring the pressure to which the pressing member 3 is subjected. That is, the pressure abnormality can be found in time by the pressure sensor 4 so that the operator can debug the constant pressure holding device in time. Thus, the pressure sensor 4 can ensure that the holding pressure meets the standard, thereby being beneficial to improving the product yield.

As shown in fig. 1, in one embodiment, the constant dwell device further includes a drive assembly 6. Specifically, the drive assembly 6 is provided on the frame 1. It is easy to understand that the driving assembly 6 drives the carrier 2 to move downward, thereby driving the pressing member 3 at the lower end of the carrier 2 to move downward to a predetermined position so that the pressing member 3 maintains pressure on the product. Therefore, the driving assembly 6 is arranged, so that the position of the pressing component 3 is adjusted, the pressing component 3 can be moved downwards to keep pressure on a product, and the pressing component 3 can be moved upwards to take out the product with the pressure keeping operation completed.

Fig. 2 and 3 are schematic structural views of another two views of a constant pressure maintaining device with pressure feedback according to an embodiment of the present utility model, and in combination with fig. 1 to 3, the driving assembly 6 includes a connecting member 61 and a driving member 62. Specifically, the connection member 61 is movably provided on the frame 1, and is connected with the carrier member 2. That is, the movement of the connecting member 61 may move the carrier 2. The structure of the connector 61 may be set as needed, and is not limited herein. Further, the driving member 62 is disposed on the frame 1 and configured to drive the connecting member 61 to move, thereby driving the carrier 2 to move, and driving the pressing member 3 to move, so that the pressing member 3 can hold the product under pressure, or the pressing member 3 is disengaged from the product to take out the product. It should be further noted that the driving member 62 in this embodiment is an air cylinder, and a piston rod of the air cylinder is connected to the connecting member 61, so that the movement of the connecting member 61 is achieved. As an alternative embodiment, the driving member 62 may be another driving device such as an electric cylinder, a linear motor, or the like.

As shown in fig. 2, in one embodiment, the drive assembly 6 further comprises a first rail 63. Specifically, the first guide rail 63 is provided on the frame 1 in the vertical direction. Further, the connecting member 61 is slidably disposed on the first rail 63 so as to be slidable up and down along the first rail 63 by the driving of the driving member 62. It will be readily appreciated that by providing the first guide rail 63 helps to ensure the accuracy of the movement track of the connecting member 61, that is, the movement track of the pressing member 3, it is possible to ensure that the weight 5 applies pressure in the vertical direction to ensure that the dwell pressure meets the standard. On the other hand, by providing the first guide rail 63, the pressing member 3 can be prevented from colliding with the product due to the accuracy problem of the movement locus, and thus a certain protection effect is provided to the product. In the present embodiment, two first guide rails 63 are provided and are disposed in parallel to the frame 1. It will be readily appreciated that the connector 61 is slidably disposed on two first rails 63. Thereby, the two first guide rails 63 can further ensure the accuracy of the moving track of the connecting member 61, and avoid the pressing member 3 from being damaged by the shifting of the connecting member 61.

As shown in fig. 3, in one embodiment, the drive assembly 6 further includes a bumper 64 and/or a stop 65. Wherein a bumper 64 is provided on the frame 1 and is configured to slow and stop the downward moving connector 61. It will be readily appreciated that when the driving member 62 drives the link 61 downwardly, the link 61 contacts the bumper 64, i.e., is decelerated to a full stop by the bumper 64. Therefore, the buffer 64 can prevent the pressing part 3 from directly colliding with the product, thereby being beneficial to protecting the product and improving the yield of the product. On the other hand, a stopper 65 is provided on the frame 1 and configured to block the downward movement of the link 61. It will be readily appreciated that when the driving member 62 drives the link 61 downwardly, the link 61 is blocked by the stopper 65 from continuing to move downwardly. Therefore, the stopper 65 can prevent the pressing member 3 from being excessively moved to collide with the product, thereby contributing to the protection of the product and improving the yield of the product.

In one embodiment, as shown in fig. 2, a second rail 66 is provided on the connector 61. Specifically, the second rail 66 is disposed in the vertical direction, and the carrier 2 is slidably disposed on the second rail 66. Thereby, when the weight 5 is disposed at the upper end of the carrier 2, the carrier 2 can move downward along the second guide rail 66; when the driving member 62 drives the connecting member 61 to bring the pressing member 3 into abutment with the product, the carrier 2 can be moved upward along the second guide rail 66. It will be readily appreciated that provision of the second guide rail 66 helps to ensure the accuracy of the movement locus of the carrier 2, that is, the movement locus of the pressing member 3, so that it is possible to ensure that the weight 5 applies pressure in the vertical direction to ensure that the holding pressure meets the standard. On the other hand, by providing the second guide rail 66, the pressing member 3 is prevented from colliding with the product due to the accuracy problem of the movement locus, and thus a certain protection effect is provided to the product. In the present embodiment, two second guide rails 66 are provided and are disposed in parallel to the connecting member 61. It will be readily appreciated that the carrier 2 is slidably disposed on two second guide rails 66. Thereby, the two second guide rails 66 can further ensure the accuracy of the moving track of the carrier 2, and avoid the carrier 2 from shifting to cause the pressing component 3 to damage the product.

In one embodiment, as shown in fig. 1, the carrier 2 is provided with relief holes 21. In the present embodiment, the escape holes 21 are provided in the horizontal direction, and have a rectangular cross-sectional shape. Further, the connecting member 61 is provided with a stopper 67. Specifically, the stopper 67 extends into the escape hole 21. When the weight 5 is disposed at the upper end of the carrier 2 to move the carrier 2 downward, the stopper 67 abuts against the inner wall of the avoidance hole 21, thereby restricting the carrier 2 from moving downward. Thus, the limiting member 67 helps to avoid excessive movement of the carrier 2, that is, to avoid excessive movement of the pressing member 3 to collide with the product, thereby protecting the product. On the other hand, when the driving member 62 drives the connecting member 61 to move upward, the stopper 67 may drive the carrier 2 to move upward, so that the pressing member 3 may be separated from the product, so that the pressure-maintaining product may be taken out. It should be noted that, grooves or holes for reducing the mass may be provided on both sides of the escape hole 21 to reduce the influence of the weight of the carrier 2 on the holding pressure.

As shown in fig. 2, in one embodiment, the pressing member 3 includes a fixing piece 31 and a pressing head 32. Specifically, fig. 4 is a schematic structural view of a fixing member provided in the embodiment of the present utility model, and fig. 5 is a schematic structural view of a pressure head provided in the embodiment of the present utility model, and, as shown in fig. 4-5, a T-shaped slot 311 is provided on the fixing member 31 and is disposed at the lower end of the pressure sensor 4. Further, a protrusion 321 is formed on the ram 32, and the protrusion 321 is matched with the T-shaped groove 311. Thus, the pressing head 32 may be inserted into the T-shaped groove 311 in a horizontal direction through the protrusion 321, thereby achieving detachable installation of the pressing head 32, so that the corresponding pressing head 32 can be selectively replaced according to different products. It will be readily appreciated that the bottom of the ram 32 may be provided with a contoured structure to provide a dwell function for different products. On the other hand, when the pressing head 32 is mounted on the fixing member 31 through the boss 321, the locking member 33 may play a role of locking the pressing head 32 and the fixing member 31 to prevent the pressing head 32 from sliding down in the horizontal direction.

As shown in fig. 4, in one embodiment, the bottom of the T-shaped slot 311 is provided with a first magnet 312. Correspondingly, as shown in fig. 5, the top end of the protruding portion 321 is provided with a second magnet 322. Thus, when the pressing head 32 is inserted into the T-shaped groove 311 through the protrusion 321, the second magnet 322 may attract the first magnet 312, so that the pressing head 32 may be fixed at a predetermined position by a magnetic force. That is, by providing the first magnet 312 and the second magnet 322, the ram 32 can be prevented from sliding down, and the ram 32 can be positioned at a predetermined position, so that the ram 32 can press the correct position of the product, which helps to ensure the yield of the product.

As shown in fig. 1, in one embodiment, the carrier 2 has a locator post 22 at its upper end. Further, fig. 6 is a schematic structural diagram of a weight according to an embodiment of the present utility model, and as shown in fig. 6, a positioning hole 51 is provided on the weight 5. The positioning posts 22 and the positioning holes 51 are matched with each other, and the number, position, shape, and size may be set as needed. In this embodiment, there are two cylindrical positioning posts 22, which are spaced apart. Correspondingly, the positioning holes 51 are round holes, and the positions of the two positioning holes 51 are matched with the positioning columns 22. Thereby, the positioning column 22 can pass through the positioning hole 51, so that the weight 5 can be positioned and sleeved on the bearing piece 2. That is, different weight blocks 5 may be disposed at the same location, so that it is ensured that the weight blocks 5 may maintain a downward pressure in the vertical direction during replacement, which helps to ensure that the pressure head 32 applies an even pressure to the product, so as to achieve an improvement in product yield.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art.
