Description

Technical Field

[0001] The present invention relates to the field of intake air pressure and temperature sensor processing equipment, and in particular to an intake air pressure and temperature sensor resistor and shell assembly equipment. Background Art

[0002] The assembly process of the intake air pressure and temperature sensor involves the assembly of resistors. During the assembly process, the resistor pins need to be manually aligned and inserted into the positive and negative positioning holes of the terminal blocks on the housing. Because the space on the housing for the resistor pins to be inserted is extremely narrow, and the resistor pins are often deformed and short-circuited due to the weight of the stack, each time the pins are assembled, they need to be manually spread apart before they can be accurately inserted into the positive and negative spaces of the terminal blocks on the housing. Manual operation is very likely to cause pin damage or omission of short circuits. Because the assembly process involves steps such as resistor welding, incorrect resistor assembly will trigger subsequent chain reactions, making it difficult to maintain efficient and stable operation of the production line.

[0023] Furthermore, the divider turntable 1 is provided with a flipping station in the upstream direction of the resistance welding machine 8, and the flipping station is arranged with an XZ two-axis servo linear module slide 32, and the XZ two-axis servo linear module slide 32 is loaded with a rotary cylinder 33, and the rotary cylinder 33 is provided with an air claw 34, and the front end of the air claw 34 is installed with a contouring fork 35, and the contouring fork 35 is used to move the shell from the front positioning space 10 to the flipping positioning space 11, and to face the resistance pin 100 to the resistance welding machine 8 or the dispensing head 9.

[0024] Furthermore, the resistance welding machine 8 is mounted on a set of YZ two-axis servo linear module slides 36, and the dispensing head 9 is mounted on a set of first XYZ three-axis servo linear module slides, and the dispensing head is used to apply UV glue; the divider turntable 1 is further provided with a UV surface light source 37 and an offline transport air claw 38 in the downstream direction of the dispensing head 9, and the offline transport air claw 38 is hoisted on a set of second XYZ three-axis servo linear module slides 39; the divider turntable 1 is further provided with a laser engraving machine 40 in the upstream direction of the forming pin 4, and the UV surface light source 37 is equipped with a product defect detection visual camera, and the laser engraving machine 40 is used to cooperate with the product defect detection visual camera to realize the traceability of the resistance product quality; the resistor loading robot 6 is externally connected to a flexible vibration disk 41, and the shell loading robot 6 is externally docked with a shell tray 42.

Figure 2The flip positioning space 11 is positioned as shown. This results in a pin 100 facing upwards. Figure 13 As shown, the resistance welding machine 8 reaches the working position under the drive of the YZ two-axis servo linear module slide 36, and welds the right-angle pin 100 of the resistor to the metal electrode embedded in the shell.

[0028] like Figure 14 As shown, the dispensing head 9 applies UV glue to the pin 100 to fix the pin bend, suppress the pin shaking, and prevent the solder joint from stress damage.
