[0030] During the manufacturing process, there is a pressure-holding operation that requires vertical compression. During the pressure-holding operation, the product to be pressure-held needs to be placed on the tooling base, and then the tooling pressure head will hold the product under pressure. This process is highly dependent on the employee's product placement accuracy. The employee needs to accurately place the product in the tooling base, which reduces the work efficiency.

[0031] Figure 1 The schematic diagram of the structure of the pressure maintaining device according to the embodiment of the utility model is schematically shown. Figure 2 for Figure 1 A structural diagram of the center pressure device from another perspective. Figure 1 and 2 As shown, the utility model proposes a pressure-maintaining device. The pressure-maintaining device of the utility model includes a fixing assembly 10 and a pressure-maintaining assembly 20. The fixing assembly 10 includes a support plate 11, a fixing block and a rolling member. The fixing block and the rolling member are respectively arranged on the same side of the support plate 11. A limiting space 14 is formed between the rolling member and the fixing block. The rolling member can guide the product from the outside of the limiting space 14 to the inside of the limiting space 14. The pressure-maintaining assembly 20 is arranged on the side of the limiting space 14 away from the support plate 11. The pressure-maintaining assembly 20 includes a driving member. The driving member has a driving end. The driving end can move toward or away from the limiting space 14 to perform a pressure-maintaining operation on the product in the limiting space 14.

[0032] According to the pressure-maintaining device of the utility model, the fixed block and the rolling member are respectively arranged on the support plate 11 and form a limiting space 14 for accommodating and limiting the product. When the pressure-maintaining operation of the product is performed, the operator roughly places the product in the limiting space 14. If the product has a part located outside the limiting space 14, the part can cooperate with the rolling member in rolling. When the driving member squeezes the product, the part of the product located outside the limiting space 14 can move into the limiting space 14 under the squeezing action of the driving member. After the product completely enters the limiting space 14, the pressure-maintaining operation can be performed. Compared with the existing pressure-maintaining device, which requires manual operation of placing the product on the tooling base 30 with higher precision, the utility model can realize the position correction of the pressure-maintaining product and improve the working efficiency at the same time.

[0033] In some embodiments of the present invention, Figure 3 As shown, the fixed block includes a first fixed portion 121, the first fixed portion 121 is arranged on the support plate 11, the rolling element includes a first support portion and a first elastic roller 1311, the first support portion is connected to the support plate 11, the first elastic roller 1311 is rollably arranged on the first support portion, and the first elastic roller 1311 has a first rolling surface, and the first rolling surface is arranged toward the first fixed portion 121. In this embodiment, the first support portion is used to support and fix the first elastic roller 1311, the first elastic roller 1311 has a first rolling surface, and the first rolling surface is arranged toward the first fixed portion 121, so that the limiting space 14 between the first elastic roller 1311 and the first fixed portion 121 can limit the product in a straight line direction, ensuring the positioning accuracy of the product. At the same time, because the first elastic roller 1311 has the ability to roll, it can guide the product entering the limiting space 14, which is convenient for the product to enter the limiting space 14, thereby improving the convenience.

[0034] Specifically, in this embodiment, the first elastic roller 1311 is a silicone member 2111, which can not only guide the product to enter the limiting space 14, but also squeeze the product after entering the limiting space 14, thereby ensuring the stability of the product.

[0035] In some embodiments of the present invention, Figure 3 As shown, the fixed block includes a second fixed portion 122, and the second fixed portion 122 is arranged on the support plate 11. The rolling element includes a second support portion and a second elastic roller 1321, and the second support portion is connected to the support plate 11. The second elastic roller 1321 is rollably arranged on the second support portion, and the second elastic roller 1321 has a second rolling surface, and the second rolling surface is arranged toward the second fixed portion 122. In this embodiment, the second support portion is used to support and fix the second elastic roller 1321, and the second elastic roller 1321 has a second rolling surface and the second rolling surface is arranged toward the second fixed portion 122, so that the limiting space 14 between the second elastic roller 1321 and the second fixed portion 122 can limit the product in another straight line direction, thereby ensuring the positioning accuracy of the product. At the same time, since the second elastic roller 1321 has the ability to roll, it can guide the product entering the limiting space 14, so that the product can enter the limiting space 14 easily, thereby improving the convenience.

[0036] Specifically, in this embodiment, the second elastic roller 1321 is a silicone member 2111, which can not only guide the product to enter the limiting space 14, but also squeeze the product after entering the limiting space 14, thereby ensuring the stability of the product.

[0037] Specifically, by using the matching structure of two sets of elastic rollers and the fixing part, the position of the product in the limiting space 14 can be limited from two straight line directions, further improving the limiting ability of the fixed block and the elastic limiting member on the product.

[0038] Specifically, along the direction perpendicular to the direction of the first elastic roller 1311 toward the first fixing portion 121, there are multiple combined structures of the first elastic roller 1311 and the first fixing portion 121, which can limit multiple positions of the product. Along the direction perpendicular to the direction of the second elastic roller 1321 toward the second fixing portion 122, there are multiple combined structures of the first elastic roller 1311 and the first fixing portion 121, which can limit multiple positions of the product.

[0039] In some embodiments of the present invention, Figure 3As shown, the arrangement direction of the first fixing part 121 and the first elastic roller 1311 on the support plate 11 is set at an acute angle or a right angle to the arrangement direction of the second fixing part 122 and the second elastic roller 1321 on the support plate 11. In this embodiment, the above arrangement can make the limiting direction of the matching structure of the two sets of elastic rollers and the fixing part be set at an angle greater than or equal to zero and less than or equal to a right angle, so that the limiting range of the limiting space 14 can be turned into a plane, thereby better performing the limiting operation on the product within the plane range. Compared with the existing pressure-keeping device, which requires manual operation with high precision to place the product on the tooling base 30, the utility model can directly place the product into the limiting space 14 for positioning, thereby improving the operating efficiency of the pressure-keeping operation.

[0040] In some embodiments of the present invention, Figure 1 and 2 As shown, the pressure-maintaining device further includes a base 30, which is disposed on the side of the support plate 11 away from the fixed block, and a pressure sensor is disposed between the base 30 and the support plate 11. In this embodiment, the sensing surface of the pressure sensor abuts against the support plate 11, and can sense the driving force of the driving end of the driving member on the product in the limiting space 14. During the product pressure-maintaining process, the pressure sensor can feedback the real-time pressure and record the maximum pressure, which is convenient for the operator to observe and record in real time and carry out subsequent error correction operations.

[0041] In some embodiments of the present invention, Figure 1 and 2 As shown, a guide post 31 is also provided on the base 30, one end of the guide post 31 is connected to the base 30, and the other end of the guide post 31 passes through the support plate 11 and slides with the driving end. In this embodiment, the guide post 31 can ensure that the movement direction of the support plate 11 and the driving end is only reciprocated in one direction without deviation, so that the driving force of the driving member can accurately apply the product along the first direction, and at the same time, the holding pressure on the support plate 11 can accurately apply the pressure sensor along the first direction, and the first direction is the direction of the driving member toward the limiting space 14.

[0042] In some embodiments of the present invention, a plurality of guide posts 31 are provided, and the plurality of guide posts 31 are arranged at intervals. In this embodiment, a plurality of guide posts 31 are provided, which can further ensure that the moving direction of the driving member and the support plate 11 is parallel to the first direction, thereby improving the accuracy of the pressure holding operation and the accuracy of the pressure sensor.

[0043] In some embodiments of the present invention, Figure 1 and 2As shown, the pressure-maintaining assembly 20 further includes a fixing seat 22, which is connected to one end of the guide column 31 away from the base 30, and the driving member is arranged on the fixing seat 22 and the driving end can move toward or away from the limiting space 14. In this embodiment, the fixing seat 22 is fixedly arranged at one end of the guide column 31 away from the base 30, and can fix the driving member to improve the stability of the driving member.

[0044] In some embodiments of the present invention, Figure 1 and 2 As shown, the driving member includes a cylinder 213, a driving rod 212 and a pressing head 211, the pressing head 211 forms a driving end, the cylinder 213 is arranged on the fixed seat 22, one end of the driving rod 212 is connected to the cylinder 213, the other end of the driving rod 212 is connected to the pressing head 211, the guide column 31 passes through the support plate 11 and the pressing head 211 in sequence, and the driving rod 212 can drive the pressing head 211 to move toward or away from the limiting space 14. In this embodiment, the cylinder 213 is arranged on the side of the fixed seat 22 away from the support plate 11, one end of the driving rod 212 is connected to the cylinder 213, the other end of the driving rod 212 passes through the fixed seat 22 and is connected to the pressing head 211, the cylinder 213 can be controlled by an external control unit to drive the driving rod 212, and drive the pressing head 211 to move toward or away from the product in the limiting space 14.

[0045] In some embodiments of the present invention, Figure 1 and 2 As shown, a flexible buffer is provided on the side of the pressure head 211 facing the limiting space 14. In this embodiment, the silicone member 2111 itself has elasticity, which can reduce the damage of the pressure head 211 to the product surface. At the same time, the silicone member 2111 also has a buffering performance, which can buffer part of the driving force of the driving rod 212, reduce the pressure on the product, and avoid the problem of damage caused by excessive pressure on the product.

[0046] Furthermore, the operation process of the pressure-maintaining device of the utility model is as follows: the operator places the product roughly in the limited space 14, that is, puts one end of the product into the limited space 14 and abuts against the fixed block, and the other end of the product is set on the rolling element, and then starts the cylinder 213. The cylinder 213 will drive the pressure head 211 to squeeze the product toward the limited space 14 through the driving rod 212. Due to the action of the first elastic roller 1311 and the second elastic roller 1321 of the rolling element, the roughly placed product can be guided into the limited space 14 through the roller structure to achieve product position correction until the product is completely fitted with the limited space 14. After that, the product is squeezed to achieve pressure-maintaining operation. During this process, the pressure sensor feeds back the real-time pressure and records the maximum holding pressure until the product pressure maintenance is completed.

[0047] The pressure-maintaining device of the utility model has a simple overall structure and low cost. The position correction of the pressure-maintaining product is achieved through a simple silicone roller structure. Among them, the gas circuit of the cylinder 213 is in a normally closed state, and there is no gas circuit when it is not started, which saves gas resources. In addition, the pressure sensor provides feedback and records of the pressure-maintaining pressure to ensure traceability.

[0048] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
