Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of piezoelectric transducers, in particular to a pressurizing device for bonding piezoelectric transducers. Background Art
[0002] A piezoelectric transducer is a device that utilizes the piezoelectric effect of certain single crystal materials and the electrostrictive effect of certain polycrystalline materials to convert electrical energy into acoustic energy. During the production process of a piezoelectric transducer, it is necessary to bond the piezoelectric ceramic sheet to the metal and use a pressurizing device for production.

The utility model can place the piezoelectric ceramic on the pressure base when bonding and pressurizing by setting the extrusion mechanism and the limiting mechanism, and limit the piezoelectric ceramic by two limiting plates and two long rods of the base box, and limit the piezoelectric ceramic on the other side by two limiting plates on the pressurizing box, so that when the ceramic sheet and the metal sheet are pressurized, the piezoelectric ceramic sheet and the film are prevented from being misaligned, so that the metal sheet and the piezoelectric ceramic are kept flush.
[0004] However, in the actual operation process, the above scheme still has some shortcomings. When placing the components that need to be bonded, the operator's hands are under the pressurized box to perform preliminary assembly of the components. Once the entire device fails, it is easy to cause damage to the operator's hands, which is dangerous. Therefore, a pressurized device for bonding piezoelectric transducers is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In the embodiment, Figure 1-7 A pressurizing device for bonding a piezoelectric transducer is provided. The utility model comprises a mounting seat 1, a mounting groove 2 is provided on the top of the mounting seat 1, a moving block 3 is slidably installed inside the mounting groove 2, two placement grooves 4 are provided inside the mounting seat 1 and are symmetrically distributed on the left and right, an L-shaped connecting plate 5 is fixedly installed on the rear side of the mounting seat 1, a guide rod 6 is fixedly installed inside the left placement groove 4, a motor 7 is fixedly installed on the rear side of the L-shaped connecting plate 5, a threaded rod 8 rotatably installed inside the right placement groove 4 is fixedly connected to the front side of the output shaft of the motor 7, and the moving block 3 is fixedly installed on the front side of the output shaft of the motor 7. Two connecting blocks 9 are fixedly installed at the bottom and are symmetrically distributed on the left and right. The two connecting blocks 9 are respectively slidably connected to the outside of the guide rod 6 and are connected to the outside of the threaded rod 8 through threaded transmission. A hydraulic rod 10 is fixedly installed on the top of the L-shaped connecting plate 5, and an auxiliary plate 11 is fixedly installed on the bottom of the telescopic end of the hydraulic rod 10. A pressure sensor 12 is fixedly installed inside the auxiliary plate 11, and a pressure plate 13 is fixedly installed on the bottom of the pressure sensor 12. A control panel 14 is fixedly installed on the front side of the mounting seat 1, and a placement plate 15 is fixedly connected to the top of the moving block 3.
[0029] The control panel 14 and the pressure sensor 12 are electrically connected to each other. The pressure generated each time the pressure is pressed can be seen through the display screen above the control panel 14. When the pressure exceeds the preset range of the pressure sensor 12, the signal is transmitted to the control panel 14, and the operation of the entire device is shut down through the control panel 14, which is convenient for the operator to maintain.
[0030] As a preferred embodiment of the present invention, two through holes 16 are opened on the top of the placement plate 15 and are symmetrically distributed on the left and right sides. Limit rods 17 symmetrically distributed front to back are fixedly installed on the left and right sides of the top of the placement plate 15. The top of the placement plate 15 and the bottom of the pressure plate 13 are fixedly installed with limiting mechanisms. The limiting structure includes a movable plate, a telescopic rod, a limiting plate, and a telescopic spring.
[0031] The limiting rod 17 can initially limit the metal sheet, thereby facilitating subsequent pressurization. The limiting plate in the limiting mechanism limits the metal sheet under the action of the telescopic rod and the telescopic spring. The limiting mechanism has been disclosed in the above-mentioned comparative document, so it is not described in detail.
[0032] As a preferred embodiment of the present invention, two receiving grooves 18 are provided on the top of the mounting base 1 and are symmetrically distributed on the left and right sides. Electric push rods 19 are fixed inside the two receiving grooves 18, and push plates 20 are fixedly installed on the tops of the telescopic ends of the two electric push rods 19.
[0033] As a preference of this embodiment, the size of the through hole 16 is larger than that of the push plate 20 , and a warning light 21 is fixedly mounted on the top of the L-shaped connecting plate 5 .
[0034] When the placement plate 15 moves to above the accommodating groove 18 and the position of the through hole 16 corresponds to that of the accommodating groove 18, the top of the telescopic end of the electric push rod 19 acts on the bottom of the push plate 20 to push out the pressurized items placed on the placement plate 15, making it easy to take out and saving manpower. When the pressure sensor 12 detects that the pressure is exceeded, it also transmits a signal to the warning light 21 to alert the operator.
[0035] As a preferred embodiment of the present invention, a connecting groove 22 communicating with the interior of the placement groove 4 is formed on the rear side of the L-shaped connecting plate 5 , and the output shaft of the motor 7 is located inside the connecting groove 22 .
[0036] It is convenient to connect the output shaft of the motor 7 with the threaded rod 8 and to maintain it.
[0037] As a preferred embodiment of the present invention, two connecting columns 23 are fixedly installed on the front side of the L-shaped connecting plate 5 and are symmetrically distributed on the left and right. Two U-shaped blocks 24 are fixedly installed on the rear side of the pressure plate 13 and are symmetrically distributed on the left and right. The U-shaped blocks 24 are slidably connected to the outer sides of the connecting columns 23.
[0038] The U-shaped block 24 is slidably connected to the outer side of the connecting column 23, so that the pressing plate 13 is more stable during the up and down movement.
[0039] Working principle:
[0040] Before the product needs to be processed, the control panel 14 is used to control the start of the motor 7, so that the output shaft of the motor 7 drives the threaded rod 8 to rotate, and drives the moving block 3 to move inside the installation groove 2 under the left and right of the guide rod 6 and the connecting block 9, thereby driving the placement plate 15 above the moving block 3 to move, so that when the operator is performing preliminary installation of the product, his hands are away from the bottom of the pressing plate 13 to prevent the device from malfunctioning and causing harm to the operator;
[0041] When the product needs to be pressurized, the bottom of the telescopic end of the hydraulic rod 10 acts on the top of the auxiliary plate 11, driving the pressure plate 13 to press down. At the same time, the pressure is detected by the pressure sensor 12. If the pressure exceeds the preset pressure range, the entire device stops running and the warning light 21 flashes. At this time, both the product and the device need to be tested.
[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
