Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a table pressure servo closed-loop pressure equipment and a welding system. Background Art

[0002] The welding process of components has always been a crucial step in the production process. This step requires precise control of welding quality to ensure a reliable connection between components and circuit boards or other substrates. To achieve this goal, components usually need to be accurately aligned and fixed through clamping and fixing equipment before welding. However, there are some problems with existing clamping and fixing equipment in practical applications, which directly affect the quality and efficiency of the welding process.

[0003] Firstly, many clamping and fixing equipment on the market currently often have difficulty achieving the required precision when providing clamping force. This may be due to the mechanical structure limitations of the equipment itself, insufficient sensor sensitivity, or defects in the control system. The inaccuracy of the clamping force will cause deviations during the welding process, affecting the quality of the welding joint, and may even lead to welding defects such as cracks, pores, or deformations. These problems not only affect the welding quality but also may cause product rework and increased costs.

[0004] Secondly, existing clamping and fixing equipment is often designed for components of specific sizes or shapes and lacks versatility, making it difficult to adapt to components of different sizes and shapes. For some components with special shapes or sizes, conventional clamping equipment may not be able to provide effective clamping solutions, restricting its application in a wider range of fields. This not only affects the flexibility of production but also may lead to bottlenecks and efficiency problems on the production line.

[0005] In addition, some clamping and fixing equipment is complex to operate and requires professional personnel for adjustment and maintenance, increasing production costs and operation difficulties. The adjustment and control of the clamping force may require complex mechanical operations or precise parameter settings, which not only increase the operation difficulty but also may introduce human errors. In an automated production line, the response speed of the clamping and fixing equipment may not meet the demand for quickly replacing components, affecting production efficiency. The clamping and fixing equipment may require a long preparation time when adjusting the clamping force or replacing components, resulting in production line downtime or reduced production capacity.

[0027] This embodiment provides a tabletop pressure servo closed-loop pressure device, which is used to clamp and fix the components to be welded, so as to facilitate the external welding device to weld them. It includes: a frame 100, the frame 100 includes a top plate 110 and a bottom beam 130 respectively arranged at its top and bottom. Among them, a sensor is provided on the top plate 110; a lifting table 200, the lifting table 200 includes a bearing plate 220 and a driving mechanism 230. The driving mechanism 230 is connected to the frame 100, and the bearing plate 220 is connected to the driving mechanism 230 and approaches / separates from the top plate 110 through the driving mechanism 230 to clamp the components to be welded; a pressure detection component 300, the pressure detection component 300 includes a rotating member 310, a pressing member 330 and a pressure sensor 320. The pressure sensor 320 is connected to the bottom beam 130. The rotating member 310 is signal-connected to the sensor and the driving mechanism 230 and rotates around the rotation center line 1001. One end of the pressing member 330 is connected to the rotating member 310, and the other end rotates with the rotating member 310 to press the pressure sensor 320.

[0028] The tabletop pressure servo closed-loop pressure device described in this embodiment drives the components to be welded to move up and down along the height direction of the device through the lifting table 200 until the components are squeezed and clamped by the top plate 110. Then, the clamping force is detected in real time through the pressure detection component 300. Thus, the precise control of the clamping force of different components can be realized. Based on this, compared with the existing conventional welding clamping devices, this application has significant advantages such as a wide range of applications, a fast response speed, a high clamping accuracy, and a high controllability.

[0029] See Figure 1 and Figure 2As shown, in the present application, the frame body 100 is preferably a cubic frame. Among them, the bottom beam 130 is supported on the installation surface, the top plate 110 is arranged on the top surface of the frame body 100, and the top plate 110 is used to squeeze and clamp the upper surface of the element to be welded. The inside of the frame body 100 is a processing space, and the lifting table 200 moves up and down in the processing space, thereby driving the element to be welded closer to / away from the top plate 110. Among them, a sensor is provided in the top plate 110. When the sensor detects that the element to be welded touches the top plate 110, it can transmit a signal to the pressure detection assembly 300, and rotate and squeeze the pressure sensor 320 through the pressure detection assembly 300, thereby realizing the observation and regulation of the actual clamping pressure through the driving mechanism 230.

[0030] See Figure 1 and Figure 2 As shown, the size of the bearing plate 220 is the same as the size of the cross-section of the frame body 100, so that different types of elements can be carried, achieving the purpose of expanding the applicable range of the amplifier. Further, to improve the support strength of the bearing plate 220 and the stability during the movement process, the lifting table 200 in this embodiment further includes a body 210, the bearing plate 220 is arranged on the body 210, and a connecting portion 211 is provided on the body 210, and the connecting portion 211 is connected to the driving mechanism 230. Specifically, in the width direction of the device, two connecting portions 211 are provided on the body 210. In other embodiments, the connecting member can be set to other quantities or arranged at other positions according to actual use requirements and the nature of the element to be welded. The present invention does not make specific limitations on this. Specifically, in order to protect the movement process of the body 210 and the bearing plate 220, a protective plate 120 is further provided in the present application. The protective plate 120 is arranged in the middle and lower part of the frame body, so that it can protect at the position where the body 210 and the bearing plate 220 are most likely to generate shaking displacement, that is, the position for loading and unloading.

[0031] See Figure 1 and Figure 2As shown, the drive mechanism 230 includes a rotating shaft 231, a second driver, and two transmission chains 233. The rotating shaft 231 is connected to the second driver in a penetrating manner, and both ends of the rotating shaft 231 are respectively connected to the two transmission chains 233. Further, the second driver is disposed at the center of the rotating shaft 231 and inside the rotating member 310 to reduce the overall volume of the device. The two transmission chains 233 rotate through both ends of the rotating shaft 231 respectively, and convert the rotational driving force into a linear driving force. The connecting members are respectively connected to the two transmission chains 233, thereby enabling the lifting platform 200 to be driven by the transmission chains 233 to move up and down. Further, in order to improve the support stability of the rotating shaft 231, the drive mechanism 230 of the present application further includes at least one auxiliary bracket 234. The auxiliary bracket 234 is connected to the bottom beam 130, and is provided with a receiving groove thereon, and the rotating shaft 231 is supported in the receiving groove. Furthermore, in order to improve the connection stability between the transmission chain 233 and the rotating shaft 231 and prevent them from disengaging due to relative displacement during rotation, the drive mechanism 230 of the present application further includes a fixing bracket 232. The fixing bracket 232 is connected to the frame body 100, and both ends of the rotating shaft 231 are rotatably connected to the fixing bracket 232.

[0032] See Figure 3 and Figure 4 As shown, the rotating member 310 in this embodiment includes a housing 311, a pressing plate 312, and a first driver 313. The housing 311 is connected to the working end of the first driver 313. The pressing plate 312 is connected to the housing 311 and extends towards the pressure sensor 320. The pressing member 330 is connected to the connecting end of the pressing plate 312. Further, in order to improve the detection accuracy of the pressure sensor 320, the pressure detection assembly 300 of the present application further includes a support block 340. The support block 340 is connected to the bottom beam 130, and the pressure sensor 320 is disposed on the top surface of the support block 340. Specifically, in order to realize the cooperation relationship between the rotating member 310 and the pressure sensor 320 in this embodiment, a through groove is further provided on the rotating member 310, and the rotating shaft 231 penetrates through the through groove. When the first driver 313 works, the housing 311 and the pressing plate 312 can rotate synchronously around the rotation center line 1001, thereby realizing the pressurization of the pressure sensor 320.

[0033] This embodiment further includes a control system. The sensor, the drive mechanism 230, the rotating member 310, and the pressure sensor 320 are respectively connected to the control system.

[0034] The working process of the tabletop pressure servo closed-loop pressure device in this embodiment is described below: In this application, first, the component to be welded needs to be placed on the carrier plate 220. Subsequently, the carrier plate 220 moves towards the top plate 110 under the action of the driving mechanism 230. When the component contacts the top plate 110, the sensor receives this signal and transmits it to the control system. At this time, the control system regulates the rotating member 310 to start rotating. Based on this, during the further upward extrusion of the carrier plate 220, the rotating member 310 can drive the pressing plate 312 to gradually press the pressure sensor 320, thereby reflecting the actual extrusion and clamping force received by the component. When the value of the pressure sensor 320 reaches the predetermined parameter, the control system stops the driving mechanism 230, thereby ensuring that the component undergoes the subsequent welding process under the action of a constant pressure clamp. Further, during the actual use process, the operator can adjust the driving mechanism 230 and the rotating member 310 in real time through the control system, thereby improving the flexibility of the use of this device. The degree of automation during the actual use of this device can also be improved through parameter presetting.

[0037] In summary, for the tabletop pressure servo closed-loop pressure device and the welding system described in this utility model, the lifting table 200 drives the component to be welded to move up and down along the height direction of this device until the component is extruded and clamped by the top plate 110. Then, the clamping force is detected in real time through the pressure detection component 300, thereby enabling precise control of the clamping force of different components. Based on this, compared with the existing conventional welding clamping devices, this application has significant advantages such as a wide application range, a fast response speed, a high clamping accuracy, and a high controllability.
