[0030] In modern intelligent manufacturing, robot hemming equipment is usually used to perform hemming and pressing operations on the car body. However, the robot hemming equipment does not have a pressure monitoring and alarm function. It is impossible to monitor and alarm the pressure in real time during the hemming operation. When the hemming operation is abnormal, it is impossible to issue a timely warning, such as the roller head spring breaking and getting stuck, the roller shaft or bearing breaking, the roller head spring elasticity attenuation, etc., which may lead to abnormal pressure during operation.

[0031] In order to solve the technical problems existing in the related art, the present application provides a pressing monitoring device, see Figure 1-Figure 4 , Figure 1 is a schematic structural block diagram of an embodiment of a compression monitoring device provided by the present application, Figure 2 is a schematic structural diagram of an embodiment of a compression monitoring device provided by the present application, Figure 3 yes Figure 2 The schematic diagram of the structure of the compression monitoring device shown in the top view, Figure 4 yes Figure 3 The cross-sectional structure diagram of the pressure monitoring device along the AA direction is shown.

[0032] The pressing monitoring device 1 includes an alarm 80, a pressure sensor 30, a pressing component 10, an elastic component 20, and a controller 90. The pressing component 10 is used to move along a pressing direction Y to press the object to be processed. The elastic component 20 and the pressure sensor 30 are arranged relatively to each other in the pressing direction Y. The elastic component 20 is transmission-connected to the pressing component 10. The pressing component 10 can drive the elastic component 20 to move along the pressing direction Y so that the elastic component 20 presses the pressure sensor 30. The controller 90 is communicatively connected to the pressure sensor 30. The controller 90 is used to receive the pressure signal generated by the pressure sensor 30 and control the alarm 80 to work according to the pressure signal.

[0033] The pressing component 10 is used to perform a rolling and pressing operation on the workpiece to be processed. When the pressing component 10 is in operation, it moves along the pressing direction Y and drives the elastic component 20 to move along the pressing direction Y, thereby transmitting the pressure of the pressing component 10 during operation to the elastic component 20, and the elastic component 20 then transmits the pressure to the pressure sensor 30, so that the pressure sensor 30 can monitor the pressure and output a pressure signal. The pressure signal output by the pressure sensor 30 can be a current signal, and the controller 90 receives the pressure signal, processes it, and controls the alarm 80 to work according to the pressure signal. The alarm 80 can be an audible and visual alarm 80, which emits a buzzer and flashes a light when an alarm is sounded, thereby reminding the inspector that the operation is abnormal.

[0034] The controller 90 includes an analog module and a logic function module, etc. The analog module is used to convert the pressure signal output by the pressure sensor 30 into a real data type, and display the pressure information on the human-computer interaction screen through the display. The information displayed on the human-computer interaction screen includes a pressure data graph, a pressure alarm information bar, a reset button, the current pressure value, the pressure setting lower limit value, the pressure setting upper limit value and other information. When the pressure exceeds the pressure setting lower limit value or the pressure setting upper limit value, an alarm message will appear in the pressure alarm information bar, and the controller 90 controls the alarm 80 to work according to the pressure signal, and the reset button can eliminate the alarm message. The controller 90 is a programmable controller 90, so the pressure setting lower limit value and the pressure setting upper limit value when the alarm is triggered can be set. In one embodiment, the pressure setting upper limit value can be 600N, and the pressure setting lower limit value can be 10N. Of course, it can also be set to other values, depending on the actual situation. The controller 90 is turned on when the robot hemming device is turned on. When the robot hemming device exits the working program, the controller 90 turns off the pressure monitoring and alarm functions, stops collecting pressure information, and the circuit elements work under a 24V switching power supply through a voltage converter.

[0037] There are multiple pressing rollers 110 , which are arranged at intervals around the pressing direction Y and are respectively connected to the transmission bracket 120 .

[0038] The pressing rollers 110 connected to the bottom of the transmission bracket 120 are spaced apart in the circumferential direction around the pressing direction Y. Each pressing roller 110 has a different shape to accommodate objects to be processed of different shapes. The number of pressing rollers 110 in the present application is three, and may also be other numbers, such as four, depending on actual conditions.

[0042] The slide rail 60 is fixedly connected to the fixed bracket 40, so that the slider 50 can move on the slide rail 60. The transmission bracket 120 and the slider 50 are fixedly connected, so that when the pressing component 10 is working, it can move along the pressing direction Y on the slide rail 60, thereby driving the elastic component 20 to move along the pressing direction Y, and then transferring the pressure to the elastic component 20.

[0043] The elastic component 20 includes an elastic member 210, a connecting member 220 and an abutting member 230. The connecting member 220 is connected to the transmission bracket 120.

The elastic piece 210 can be a spring. The abutment 230 is in contact with the pressure sensor 30 and is located at the bottom of the elastic piece 210. It has the function of fixing the elastic piece 210. At the same time, the elastic piece 210 presses the abutment 230, and the abutment 230 presses the pressure sensor 30, thereby transferring the pressure on the elastic piece 210 to the pressure sensor 30.

[0045] The abutment member 230 includes an abutment portion 231 and a sleeve portion 232. The radial dimension of the abutment portion 231 is larger than the radial dimension of the sleeve portion 232. The sleeve portion 232 is connected to the side of the abutment portion 231 away from the pressure sensor 30 and extends along the pressing direction Y. The elastic member 210 is sleeved on the outside of the sleeve portion 232. One end of the elastic member 210 abuts against the abutment portion 231, and the other end abuts against the connecting member 220.

[0046] The abutment member 230 is used to fix the bottom of the elastic member 210 and transmit the pressure to the pressure sensor 30. The abutment portion 231 is cylindrical and is used for the elastic member 210 to press the pressure sensor 30 through the abutment portion 231.
