They are widely used in industries such as medical, automobile manufacturing, and furniture production; in the existing mechanical parts manufacturing industry. At present, for the detection and assembly technology of pneumatic rods, for example, the Chinese patent CN201921276630.6 applied by our company in 2019 discloses a pneumatic rod detection and assembly production line, which includes a support mechanism, an electrical control mechanism, a feeding mechanism, a pressure detection mechanism, a switch shaft mounting mechanism, and a lettering and buffer pad mounting mechanism. The support mechanism includes a support frame, and the electrical control mechanism is electrically connected to the feeding mechanism, the pressure detection mechanism, the switch shaft mounting mechanism, the lettering and buffer pad mounting mechanism, respectively. The feeding mechanism, the pressure detection mechanism, the switch shaft mounting mechanism, and the lettering and buffer pad mounting mechanism are placed on the support frame in sequence. However, the structure disclosed in the patent requires manual sorting when the pressure detection mechanism detects unqualified pneumatic rods (including insufficient pressure and excessive pressure), thereby affecting the working efficiency of the entire production equipment.

[0046] Combination Figure 1 , Figure 2 and Figure 3 As shown, unqualified pressure includes two situations: insufficient pressure and excessive pressure. The unqualified pressure pneumatic rod rejection mechanism 17 includes a cylinder lifting component 171, a grabbing component 172 straddling the pressure detection mechanism 14, and a supporting platform 173 located in the movement direction of the grabbing component 172. The cylinder lifting component 171 and the grabbing component 172 are both electrically connected to the electrical control mechanism 12, and the supporting platform 173 is connected to the support mechanism 11 (support frame 111).

[0047] exist Figure 2 In the figure, the air cylinder lifting component 171 includes a lifting cylinder 1711 and a blocking block 1712 located at the head of the cylinder. The blocking block 1712 is in the shape of an elongated strip and is made of polyvinyl chloride with good wear resistance. A corresponding elongated through hole is provided on the first working platform 142. The width and length of the elongated through hole are both greater than the width and length of the blocking block 1712. The blocking block 1712 is perpendicular to the movement direction of the gas pressure rod and can exceed the first working platform 142 and block the movement of the gas pressure rod 18 under the action of the lifting cylinder 1711.

[0048] In order to improve the precise blocking of the blocking block 1712, the lifting cylinder 1711 is vertically fixed on the supporting mechanism 11 (support frame 111) and is obliquely supported by the supporting rod 1713, and the stability of the lifting cylinder 1711 is enhanced by the supporting rod 1713.

[0049] Combination Figure 1 and Figure 2 The grabbing component 172 includes a truss 1721 and an electric manipulator 1722.

[0050] According to the above-mentioned classification of unqualified products into two categories, the supporting platform 173 includes a first platform 1731 and a second platform 1732. The first platform 1731 is located above the second platform 1732 and the entrance end of the first platform 1731 is far away from the electric manipulator 1722.

[0052] The basic structure of the production line of the utility model is the same as that of CN201921276630.6. The specific working process is different in that the pressure detection mechanism completes the test of the pressure of the pneumatic rod through an automatic pressure testing machine. The pneumatic rod that passes the pressure test enters the next process (installing the switch shaft). For unqualified pneumatic rods, the automatic pressure testing machine feeds back a signal to the PLC controller, and at the same time controls the action of the lifting cylinder to lift the blocking block beyond the table surface of the first working platform 142, thereby preventing the pneumatic rod from rolling. The PLC controller controls the electric manipulator to grab the pneumatic rod, and places the pneumatic rod on the first platform 1731 and the second platform 1732 respectively according to the measurement results (insufficient pressure or excessive pressure), and then the lifting cylinder drives the blocking block to descend, waiting for the next unqualified pneumatic rod to appear.
