[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1The present invention provides a pin loading device, comprising: a frame 1, a feeding mechanism 2 arranged on the side of the frame for supplying pin materials, a first jig assembly line 3, a second jig assembly line 4 arranged above the frame, a third jig assembly line 5 and a robot 6 arranged on the side of the second jig assembly line, the robot is provided with a CCD camera device and a product suction mechanism 7, the first jig assembly line is used to carry jigs for assembling with pin materials, a pushing mechanism 8 is arranged at the joint of the first jig assembly line and the second jig assembly line, and a first blocking cylinder 9, a jig positioning mechanism 10 and a jig transfer mechanism 11 are sequentially arranged on the second jig assembly line along the jig transmission direction.

[0027] like Figure 2-3 As shown, the feeding mechanism 2 includes a vibration plate 21, a feeding track 22 connected to the vibration plate, and a photographing platform 23 connected to the feeding track. A first direct vibration motor 24 is arranged below the feeding track, a second direct vibration motor 25 is arranged below the photographing platform, and a recovery bin 26 connected to the end of the photographing platform is arranged on the frame. When feeding, the pin material is poured into the vibration plate, and a protective cover is arranged on the periphery of the vibration plate. The vibration plate vibrates the material evenly and drops it evenly onto the feeding track. A first direct vibration motor is installed under the feeding track. Driven by the direct vibration motor, the material is smoothly sent to the photographing platform. When the material falls into the photographing platform, the CCD photographing device identifies the position of the material that can be grasped, the robot absorbs the material and puts it into the slot of the fixture, and the second direct vibration motor under the grasping platform is started to send the material that cannot be identified and grasped to the recovery bin. A photoelectric sensor 27 is installed at the front end of the feeding track for the stop point of rapid feeding during the first feeding.

[0028] like Figure 4 As shown, the product suction mechanism 7 includes a slide cylinder 71 arranged on the robot and a plurality of suction cups 72 arranged on the slide cylinder for sucking the pin materials, which suck the disordered pin materials in sequence and put them into the groove of the fixture at one time.

[0029] like Figure 5-9As shown, the pushing mechanism 8 is a rodless cylinder, which is used to push the jig on the first jig assembly line to the second jig assembly line. A jig error prevention sensor 12 and a proximity sensor 13 are provided at the end of the first jig assembly line. A first opposing photoelectric switch 14, a second opposing photoelectric switch 15, a third opposing photoelectric switch 16 and a fourth opposing photoelectric switch 17 are sequentially provided on the second jig assembly line along the jig transmission direction. The jigs are manually arranged on the first jig assembly line (as close to the operating edge as possible). The proximity sensor detects that the product is in place and the first jig assembly line stops. After receiving the feeding signal, the pushing mechanism pushes a single jig to the second jig assembly line. The first jig assembly line sends the next jig to the proximity sensor to wait. The error prevention detection sensor set on the first jig assembly line will alarm to remind the operator to correct the jig when the jig is manually placed in the wrong direction.

[0030] Furthermore, the jig positioning mechanism 10 includes a second blocking cylinder 101 arranged on one side of the second jig assembly line, a positioning cylinder 102 arranged on the other side of the second jig assembly line, and a first photoelectric sensing switch 103, and the jig transferring mechanism 11 includes a support frame 111 arranged on the side of the second jig assembly line, a lifting cylinder 112 arranged on the support frame, a translation cylinder 113 arranged below the lifting cylinder, a clamp cylinder 114 arranged on the translation cylinder, a clamp claw 115 installed below the clamp cylinder, and a second photoelectric sensing switch 116.

[0031] Specifically, the jig flows to the second jig assembly line, and the first photoelectric switch detects the incoming material. At this time, the first blocking cylinder is in an extended state. After receiving the feeding signal from the system, the first blocking cylinder retracts. The jig stops and waits after passing through the second photoelectric switch. When it receives the feeding signal from the system again, the jig flows into the discharge station. At this time, the first photoelectric sensing switch senses that the jig is in place, and the positioning mechanism accurately positions it. After the product suction mechanism on the robot fills the jig with materials, it is released. The jig flows to the third photoelectric switch, and the system prompts the previous station to release it. When the fully loaded jig flows to the end of the second jig assembly line, the second photoelectric sensing switch detects that it is in place, and the jig transfer device transfers the fully loaded jig to the third jig assembly line.

[0032] The action process of the fixture positioning mechanism: the second blocking cylinder extends - the fixture is blocked and stops, the first photoelectric sensor switch senses that the fixture is in place, and the positioning cylinder is pushed out. At this time, the positioning roller is stuck in the V groove of the fixture, and the robot places the pin material.

[0033] The action process of the fixture transfer mechanism: the second photoelectric sensor switch at the end of the second fixture assembly line detects that the fixture is in place, the translation cylinder moves the clamping cylinder to the top of the fixture, the clamping cylinder opens, the lifting cylinder descends, the clamping cylinder clamps the fixture, the lifting cylinder rises, the translation cylinder moves to the top of the third fixture assembly line, the fourth photoelectric sensor detects that there is no fixture below, the lifting cylinder descends, the clamping cylinder releases the fixture, and the fixture is transferred to the end on the third fixture assembly line.

[0034] Furthermore, a third photoelectric sensor switch 51 is provided at the end of the third fixture assembly line 5. When the third photoelectric sensor switch detects the fixture, the system reminds manual material collection.

[0035] The beneficial effects of the pin feeding equipment of the present invention are: automatic feeding by a vibration plate, positioning the material picking position of the pin material by setting a CCD device to take pictures, and the fixture positioning mechanism on the second fixture assembly line accurately positions the fixture, which provides a guarantee for the pins to be smoothly and accurately placed in the fixture, and reduces the wear of the pins as much as possible; ensures the accuracy of picking and placing the pins in the case of disordered incoming materials; and ensures that the arrangement CT of the pins is less than or equal to 2s / piece in the case of disordered incoming materials.

[0036] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
