The clamping cylinder is vertically mounted on the triangular hanger of the tooling frame with its piston end at the bottom. The clamping cylinder is connected to an external air source via a pipe, and a solenoid valve is installed on the pipe. The support structure is mounted on the tooling frame below the clamping cylinder and is used to support and limit the windshield. The piston end of the clamping cylinder is equipped with a pressing head, and the rearview mirror mount is installed directly below the pressing head. The pressing head is used to press and bond the rearview mirror mount to the windshield. The foot switch, the coil of the time relay, and the time relay's energizing delay disconnect contact are connected in series to form the first circuit. The first normally open contact of the time relay is connected in parallel across the two ends of the foot switch.

It should be noted that in this specification, relational terms such as "first" and "second" are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0017] This utility model provides an embodiment: like Figure 1 , Figure 2 As shown, a tooling for preventing errors in bonding rearview mirror mounts to a car windshield includes: a tooling frame 1, a foot switch 2, a time relay 3, a solenoid valve 4, a clamping cylinder 5, and a support structure. The clamping cylinder 5 is vertically mounted on a triangular hanger of the tooling frame 1 with its piston end located below. The clamping cylinder 5 is connected to an external air source via a pipe, and the solenoid valve 4 is installed on the pipe. The support structure is installed on the tooling frame 1 below the clamping cylinder 5 and is used to support and limit the windshield. The piston end of the clamping cylinder 5 is equipped with a downward pressing head. The installation position is directly below the pressure head, which is used to press and adhere the rearview mirror mount to the windshield. The foot switch 2, the coil of the time relay 3, and the energized delay disconnect contact of the time relay 3 are connected in series to form the first circuit. The first normally open contact of the time relay 3 is connected in parallel across the two ends of the foot switch 2. The second normally open contact of the time relay 3 is connected in series with the solenoid valve 4 to form the second circuit. The first and second circuits are connected in parallel and then connected to an external power supply. The foot switch 2 and the time relay 3 are used to control the adhesion time of the rearview mirror mount. The time relay 3 is a JZF-10 forward / reverse control time relay.

[0018] In this embodiment, the support structure includes at least two nylon baffles 601 and at least three nylon support columns 602. The at least three nylon support columns 602 are arranged in a triangular shape, and a polyurethane disc is provided at the upper end of each nylon support column 602. The at least two nylon baffles 601 are arranged in a shape that matches one end face of the windshield to limit its movement. The lower pressure head at the piston end of the pressing cylinder 5 is a polyurethane disc, which cooperates with the polyurethane disc at the upper end of the nylon support column 602 to achieve flexible pressing of the windshield.

[0019] To monitor the pipeline pressure during the bonding process, a smart pressure digital display 701 is connected to the pipeline of the clamping cylinder 5 via a tee. The smart pressure digital display 701 detects the pressure inside the pipeline and triggers an alarm 702 electrically connected to it to emit an audible and visual alarm. The alarm 702 has a built-in alarm threshold comparison chip. The alarm threshold comparison chip uses simple threshold comparison logic; it alarms when the pressure exceeds the threshold, and the alarm 702 does not activate when the pressure is below the threshold. This is prior art and not the content to be protected in this application. The smart pressure digital display 701, alarm 702, time relay 3, and solenoid valve 4 are all installed in a box-shaped structure 8 mounted on the side wall of the fixture 1. The foot switch 2 is located on the ground outside the fixture 1. The model of the smart pressure digital display 701 is YKN10A; the model of the alarm 702 is LTE-5061.

[0020] Specific workflow: After the windshield is brought into contact with and limited by the supporting structure, the rearview mirror mount is placed on the windshield at the installation position. The foot switch 2 is pressed, the coil of the time relay 3 is energized, and its first normally open contact is instantly engaged and self-locked to keep the first circuit open. Its second normally open contact is instantly engaged, so that the solenoid valve 4 is energized, which controls the air supply to the pipe of the pressing cylinder 5, causing the pressing cylinder 5 to descend and press and bond the rearview mirror mount.

[0021] The time relay 3 is set to a pressing and bonding time of 5-6 seconds, which is a suitable time for stable bonding of the rearview mirror mount obtained through testing. After the set time of the time relay 3 is reached, the power-on delay disconnect contact of the time relay 3 opens, and both the first circuit and the second circuit are disconnected, thus ending the process.

[0022] During the above process, the pipeline pressure is monitored by an intelligent digital pressure display 701 and an alarm 702. Once the pressure threshold is exceeded, the alarm 702 sounds an alarm, and relevant personnel press the emergency stop button SB1. In normal operation, if a stop is required, the stop button SB2 is pressed. Both the emergency stop button SB1 and the stop button SB2 are located on the tooling frame 1.

[0023] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
