[0022] Example 1

[0023] like Figure 1-4 The first embodiment of this utility model is shown, which provides a multi-dimensional force sensor patch pressurizing device, including a housing 100, a pressurizing assembly 200 including a hot air blower 210, a fixing plate 220 fixed to the upper end of the inner cavity of the housing 100, a first cylinder 230 fixed to the top of the fixing plate 220, a bracket 240 fixed to the output end of the first cylinder 230, a pneumatic gripper 250 located at the bottom of the bracket 240 for clamping the patch, a sliding groove 260 formed on the surface of the bracket 240, and fastening bolts 270 for fixing the position of the pneumatic gripper 250. The pneumatic gripper 250 is provided in four sets. A conveying assembly 300 includes a frame 3. 10. A conveyor belt 320 for conveying a multidimensional force sensor, an active conveyor roller 350 and a driven conveyor roller 360, a servo motor 330 and a reducer 340 for providing power, a support plate 370 and a support roller 380 for supporting the conveyor belt 320, and an L-shaped plate 390 for supporting the frame 310, and a limiting assembly 400, including a vertical plate 410, a second cylinder 420 fixed to the surface of the vertical plate 410, and an arc plate 430 fixed to the output end of the second cylinder 420, and the limiting assembly 400 is provided in two sets, which are respectively fixed to the front end and the rear end of the top of the frame 310. The limiting assembly 400 is used to fix the multidimensional force sensor.

[0024] like Figure 1-4As shown, the pressurizing assembly 200 uses pneumatic grippers 250 to clamp the patch, and four sets are provided. Compared with the traditional method of tightening bolts, the pneumatic grippers 250 are easier and faster to operate. Simply controlling the switch of the pneumatic grippers 250 quickly pressurizes the patch, eliminating the need to tighten bolts individually, thus greatly improving operational efficiency. Simultaneously, the pneumatic grippers 250 can provide relatively stable and high pressure. Driven by compressed air, its pressurizing capacity can be adjusted according to actual needs, overcoming the limited pressure of traditional bolt pressurization. This better ensures a tighter fit between the patch and the multi-dimensional force sensor, thereby improving the patch's stability. The air outlet of the hot air blower 210 is connected to the inner cavity of the housing 100, providing a suitable temperature environment during pressurization. The hot air blower 210 further enhances the adhesion between the patch and the sensor beam. The multi-dimensional force sensor is continuously conveyed within the device via the conveyor assembly 300. Through the cooperation of the conveyor belt 320, active conveyor roller 350, driven conveyor roller 360, servo motor 330, and reducer 340, the multi-dimensional force sensor can be quickly and stably conveyed to the pressurization position, improving overall work efficiency. The limiting assembly 400 consists of a vertical plate 410, a second cylinder 420, and an arc-shaped plate 430. During pressurization, the limiting assembly 400 can fix the position of the multi-dimensional force sensor, ensuring it receives pressurization in the correct position. The sensor is conveyed to the pressurization position via the conveyor assembly 300, the limiting assembly 400 fixes the sensor, the pressurization assembly 200 pressurizes the patch, and the hot air blower 210 provides a suitable temperature. All components work together to complete the pressurization operation of the multi-dimensional force sensor patch.

[0025] Example 2

[0026] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the air outlet of the hot air blower 210 is connected to the inner cavity of the housing 100, the output end of the first cylinder 230 passes through the fixing plate 220 and is fixedly connected to the bracket 240, and one end of the fastening bolt 270 passes through the slide groove 260 and is threadedly connected to the pneumatic gripper 250.

[0028] One end of the L-shaped plate 390 is fixedly connected to the frame 310, and the other end of the L-shaped plate 390 is fixedly connected to the box 100. Both ends of the frame 310 extend to the outside of the box 100.

[0029] The active conveyor roller 350 is fixed to one end of the inner cavity of the frame 310 by bearings, the driven conveyor roller 360 is fixed to the other end of the inner cavity of the frame 310 by bearings, the support plate 370 is fixedly connected to the inner cavity of the frame 310, the support roller 380 is fixedly connected to the inner cavity of the frame 310 by bearings, and the conveyor belt 320 is sleeved on the surface of the active conveyor roller 350, the driven conveyor roller 360, the support plate 370 and the support roller 380.

[0030] The servo motor 330 and the reducer 340 are both fixed to the surface of the frame 310. The output shaft of the servo motor 330 is connected to the input shaft of the reducer 340, and the output shaft of the reducer 340 is connected to the active conveyor roller 350.

[0031] The upright plate 410 is fixedly connected to the frame 310, and the output end of the second cylinder 420 passes through the upright plate 410 and is fixedly connected to the arc plate 430.

[0032] like Figure 1-4 As shown, after the servo motor 330 starts, it outputs power. The power is adjusted and transmitted by the reducer 340, driving the active conveyor roller 350 to rotate. Since the conveyor belt 320 is fitted on the surface of the active conveyor roller 350, the driven conveyor roller 360, the support plate 370, and the support roller 380, the rotation of the active conveyor roller 350 will drive the conveyor belt 320 to circulate, thereby placing the multidimensional force sensor on the conveyor belt 320 for conveying. The support plate 370 and the support roller 380 play the role of supporting the conveyor belt 320 to ensure the stability of the conveying process. The L-shaped plate 390 fixes the frame 310 to the box 100 to ensure the overall stability of the conveying assembly 300. When the multidimensional force sensor is conveyed to the designated position, the two sets of limit components 400 located at the front and rear ends of the top of the frame 310 start to work, and the second cylinder 4 When cylinder 20 is activated, its output end pushes the arc plate 430 towards the multi-dimensional force sensor until the arc plate 430 contacts and fixes the multi-dimensional force sensor, preventing displacement of the multi-dimensional force sensor during patch pressurization and ensuring the accuracy of patch pressurization. Hot air blower 210 is turned on, and its air outlet delivers hot air into the inner cavity of housing 100, creating a suitable temperature environment for patch pressurization, which is beneficial to improving the patch bonding effect. The outlet of hot air blower 210 can deliver hot air to the pressurization position through a pipe, thereby reducing heat loss. First cylinder 230 is activated, and its output end pushes the bracket 240 downward, so that the four sets of pneumatic grippers 250 located at the bottom of the bracket 240 approach the patch on the multi-dimensional force sensor. The pneumatic grippers 250 are activated, applying pressure to the patch, so that the patch is tightly bonded to the multi-dimensional force sensor.

[0033] In use, first, according to actual needs, adjust the position of the pneumatic gripper 250 by adjusting the position of the fastening bolt 270 in the slide 260, and fix the pneumatic gripper 250 by adjusting the fastening bolt 270. Then, apply epoxy resin evenly to the surface of the multi-dimensional force sensor beam and strain gauge. Next, attach the strain gauge coated with epoxy resin to the surface of the beam. Then, place the multi-dimensional force sensor on the surface of the conveyor belt 320. After the servo motor 330 starts, it outputs power, which is transmitted to the reducer 340. After the speed is adjusted by the reducer 340, its output shaft drives the active conveyor roller 350 to rotate. Since the conveyor belt 320 is sleeved on the surface of the active conveyor roller 350, the driven conveyor roller 360, the support plate 370 and the support roller 380, the rotation of the active conveyor roller 350 will drive the conveyor belt 320 to rotate, thereby realizing the movement of the multi-dimensional force sensor on the conveyor belt 320.

[0034] When the multi-dimensional force sensor moves to the designated pressurization position along the conveyor belt 320, the limiting component 400 starts working, the second cylinder 420 is activated, and its output end pushes the arc plate 430 towards the multi-dimensional force sensor. Finally, the arc plate 430 fixes the multi-dimensional force sensor in its current position, preventing displacement during the patch pressurization process and ensuring the accuracy of the pressurization operation. After the multi-dimensional force sensor is fixed by the limiting component 400, the pressurization component 200 begins the patch pressurization operation, and the hot air fan 210 is turned on, its outlet supplying air to the inner cavity of the housing 100. Hot air is supplied to provide a suitable temperature environment for the patch pressurization process, which helps to improve the patch bonding effect. The first cylinder 230 is started, and its output end extends downward, driving the bracket 240 and the pneumatic gripper 250 installed at the bottom of the bracket 240 to move downward. The bracket 240 descends, causing the pneumatic gripper 250 to approach the patch position on the multi-dimensional force sensor. The pneumatic gripper 250 clamps the patch, realizing the pressurization operation of the patch. Through the coordinated work of the conveying component 300, the limiting component 400 and the pressurizing component 200, the patch pressurization operation of the multi-dimensional force sensor is completed.
