Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Fig. 1 and 2 show a preferred embodiment of a connector terminal insertion-in-plastic-shell tensile testing device according to an embodiment of the present invention. The tension testing device comprises a movable base 2, a driving module 1 and a sliding detection device 3 for clamping a wire connected to a terminal A. The moving base 2 is mounted on the driving module 1, and the slide detecting device 3 is slidably mounted on the moving base 2. The driving module 1 is a linear transmission mechanism of a ball screw, and the linear transmission mechanism of the ball screw drives the movable base 2 to move.
In the above embodiment, the slip detection device 3 includes the clamping assembly for clamping the wire connected to the terminal, the low friction cylinder 33, and the slider 32. The clamping assembly is fixedly mounted on a slide 32 with a low friction cylinder 33, the slide 32 is slidably mounted on the moving base 2, and the piston rod of the low friction cylinder 33 can extend and press against the moving base 2. The clamping assembly comprises a pneumatic jaw 31 for clamping the wire connected to the terminal a, the pneumatic jaw 31 being fixed to a slide 32.
After the terminal a to which the wire is connected is inserted into the case B, the case B is fixed by an external force, and before the wire on the terminal a is gripped by the pneumatic jaws 31 and pulled in the pulling-out direction, the piston rod of the low friction cylinder 33 is extended against the moving base 2 to be relatively stationary, and the pressure value at which the piston rod of the low friction cylinder 33 can be kept extended is set as the detection pressure threshold value. When the pneumatic clamping jaw 31 clamps the lead on the terminal A and the driving module 1 drives the movable base 2 to move along the lead pulling-out direction, if the sliding seat 32 and the movable base 2 slide relatively, the connector (product) is detected to be qualified; if the slide 32 and the moving base 2 are stationary relative to each other, the connector is detected as being defective.
In the above embodiment, the slide detecting device 3 further includes the pushing cylinder 34, the displacement sensor 35, and the screw 36. The displacement sensor 35 is mounted on the slide 32, the baffle 21 is fixed at one end of the moving base 2, and the slide 37 is fixed at one end of the slide 32 near the baffle 21. The tail end of the screw 36 is mounted and fixed on the baffle 21, and the slide plate 37 is slidably sleeved on the screw 36 and can abut against the head end of the screw 36, so that the slide plate 37 can move between the head end and the tail end of the screw 36. The pushing cylinder 34 is mounted on the opposite end of the slide 32 from the shutter 21, i.e. on the side of the moving base 2 close to the low friction cylinder 33. When the piston rods of the low friction cylinder 33 and the pushing cylinder 34 are extended, they can be abutted against the moving base 2, so that the slide plate 37 can be pulled to the head end of the screw 36 to stop. At this time, the slider 32 is fixed to the moving base 2 in both the extraction direction and the insertion direction of the terminal a, and the sensor lever of the displacement sensor 35 mounted on the slider 32 contacts the shutter 21.
Specifically, before the pneumatic clamping jaw 31 clamps the wire on the terminal a and pulls in the pulling-out direction, the piston rod of the low friction cylinder 33 abuts against one end of the moving base 2 with the pushing cylinder 34, and at this time, the pressure value that the piston rod of the low friction cylinder 33 can withstand is a set detection pressure threshold (the detection pressure threshold is set according to the qualification requirement of the detection product). When the driving module 1 drives the moving base 2 to move along the wire pulling-out direction, the piston rod of the pushing cylinder 34 is contracted, and the piston rod of the low friction cylinder 33 continuously abuts against the moving base 2. At this time, the piston rod of the low friction cylinder 33 receives the force along the wire pulling-out direction, and if the slide 32 and the moving base 2 slide relatively, the connector is detected to be qualified; if the slide 32 and the moving base 2 are stationary relative to each other, the connector is detected as being defective.
More specifically, before the pneumatic jaw 31 clamps the wire connected to the terminal a and pulls in the pull-out direction, the slide plate 37 abuts against the head end of the screw 36, and the sensing rod of the displacement sensor 35 contacts the shutter 21. After the terminal A connected with the lead is inserted into the rubber shell B, the rubber shell B is fixed through external force, the pneumatic clamping jaw 31 clamps the lead on the terminal A to apply force along the pulling-out direction, if the sliding seat 32 and the moving base 2 slide relatively, the sensing rod of the displacement sensor 35 abuts against the baffle 21 to shrink, the displacement sensor 35 senses that the displacement changes, and then a control signal is transmitted to control the pneumatic clamping jaw 31 to release the lead on the terminal A, so that the finished product detection is finished qualified. When the slide 32 and the moving base 2 are relatively stationary, the sensing rod of the displacement sensor 35 abuts against the baffle 21 and does not shrink, the displacement sensor 35 cannot sense the displacement and changes, the pneumatic clamping jaw 31 continues to clamp the lead on the terminal A and continues to pull out along the pulling-out direction, and the product is detected to be unqualified.
The embodiment of the invention also provides a testing method of the device for testing the tensile force of the connector terminal inserted into the rubber shell, which comprises the following steps: before the detection, the piston rod of the low friction cylinder 33 is extended and pressed against the moving base 2.
During detection, the rubber shell B with the terminal A inserted is fixed through external force, the clamping assembly clamps the wire connected to the terminal A, the driving module 1 applies force along the wire pulling direction to the moving base 2, at the moment, the piston rod of the low-friction air cylinder 33 receives acting force along the wire pulling direction, the acting force is larger than the thrust of the low-friction air cylinder 33 to the piston rod of the low-friction air cylinder, and when the thrust of the low-friction air cylinder 33 to the piston rod of the low-friction air cylinder is smaller than the reaction force of the wire to the clamping assembly along the wire inserting direction, the sliding seat 32 and the moving base 2 slide relatively, and detection is qualified. When the force acting on the low friction cylinder 33 and the pushing force of the piston rod thereof are both greater than the reaction force of the wire pair clamping assembly in the wire insertion direction, the sliding seat and the movable base are relatively static and move together, so that the detection is failed.
Specifically, before the wire on the clamp terminal a of the pneumatic clamp jaw 31 is pulled in the pulling-out direction, the low friction cylinder 33 is pressurized by the pressure regulating valve, so that the piston rod of the low friction cylinder 33 is extended and pressed against the moving base 2. According to the qualification requirement of the connector, the pressure born by the piston rod of the low friction cylinder 33 is regulated to be a detection pressure threshold, and at the moment, the sliding plate 37 abuts against the head end of the screw 36, so that the sliding seat 32 and the movable base 2 are relatively fixed, and the sensing rod of the displacement sensor 35 contacts the baffle 21.
During detection, the rubber housing B with the terminal A inserted therein is fixed by an external force, the pneumatic clamping jaw 31 clamps the wire connected to the terminal A, the driving module 1 applies a force along the wire pulling-out direction to the moving base 2, and at this time, the piston rod of the low friction cylinder 33 is acted on by a force along the wire pulling-out direction. If the sliding seat 32 and the moving base 2 slide relatively, it indicates that the tension borne by the wire on the terminal a meets the qualified requirement of the product after the terminal a is inserted into the rubber housing B, and the finished product is qualified after the production, i.e. the terminal a is inserted into the rubber housing B. In the process of the sliding seat 32 and the moving base 2 sliding relatively, the sensing rod of the displacement sensor 35 abuts against the baffle 21 to shrink, the displacement sensor 35 senses that the displacement changes and then transmits a feedback control signal to the pneumatic clamping jaw 31, and the pneumatic clamping jaw 31 releases the lead on the terminal A. If the slide 32 and the moving base 2 do not move relatively, the slide 32 and the moving base 2 move together along the direction of extracting the terminal a, which indicates that the terminal a is completely inserted into the housing B, the tensile force borne by the lead on the terminal A does not meet the qualification requirement of the product, and the finished product is unqualified, namely the terminal A is inserted into the rubber shell B and is not inserted in place. In the process that the slide 32 and the moving base 2 move along the pulling direction of the terminal a, the sensing rod of the displacement sensor 35 abuts against the baffle 21 and does not shrink, after the displacement sensor 35 does not sense that the displacement changes, a feedback control signal is not transmitted to the pneumatic clamping jaw 31, the pneumatic clamping jaw 31 continuously clamps the wire on the terminal a to move along the pulling direction of the terminal a, and the terminal a is pulled out from the rubber shell B.
In summary, the invention can automatically test the product to distinguish the qualified product and the unqualified product, and has the advantages of low labor cost and high production efficiency.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
