Specific embodiment

Just the utility model is further described with specific embodiment with reference to the accompanying drawings below, but the implementation of the utility model Mode is not limited to this.

As shown in Figure 1 to Figure 2, a kind of suction plate structure of finished product retraction plate machine, is set on finished product retraction plate machine, including with The sliding rail 1 that the relatively-stationary a pair of finished product retraction plate machine rack (not shown) is vertically arranged, the length direction of sliding rail 1 are parallel Z axis, sliding is provided with a portal frame 2 (being equipped with the sliding block matched with sliding rail 1 in two vertical arm of portal frame 2), institute on sliding rail 1 It states 2 bottom end of portal frame (i.e. two vertical arm bottom ends) and is each provided with a lower bearing 61, lower bearing 61 abuts (lower bearing with lifter cam 21 61 become sliding frictions into rolling friction, can reducing friction resistance, extension equipment life), a pair of of lifter cam 21 and first gear 22, third gear 23 is set on same lifter motion cam shaft 24, and lifter cam 21 rotates to drive portal frame 2 along Z axis Direction moves up and down, and 2 top of portal frame is provided with the iron plate 3 for capableing of front and back (along the y axis) sliding relative to portal frame 2 (specific structure are as follows: the top both ends setting of portal frame 2 is parallel to the guide post 35 of Y direction, and 3 both ends of iron plate are slideably positioned in On guide post 35), spring 36 is provided on guide post 35,36 one end of spring abuts portal frame 2, and the other end abuts iron plate 3, iron plate 3 Both ends are also set up there are two swing arm 31, and the lower end of swing arm 31 is hinged to retraction plate machine rack, and the upper end for putting wall is connected with upper bearing (metal) 32, upper bearing (metal) 32 is set in two vertical chutes at 3 both ends of iron plate, and the middle part of pendulum wall 31 is provided with middle (center) bearing 33, middle (center) bearing 33 side is provided with front and back cam 41, and front and back cam 41 and the first synchronizing wheel 42 are set on front and back camshaft 43, and first is same Step wheel 42 connects the second synchronizing wheel 45 by belt, and the second synchronizing wheel 45 is set on a transmission shaft 47 with second gear 46, the Two gears 46 connect third gear 23 by chain, and first gear 22 is connect with a driving gear 51, and driving gear 51 and one is adjusted Speed motor 52 connects, and 3 bottom magnetic of iron plate has multiple vacuum slots 34.

Working principle: such as Fig. 3, driving gear 51 is driven to rotate by governor motor 52, driving gear 51 passes through chain-driving First gear 22, since first gear 22, third gear 23 and a pair of of lifter cam 21 are coaxially disposed, three's synchronous rotary, one Lifter cam 21 is rotated, portal frame 2 can be driven to do oscilaltion campaign, carrying out suction operation, (vacuum slot 34 is first from Fig. 3 In A point drop to the point of the B in Fig. 3, draw lower section circuit board finished product 100, then with finished product from Fig. 3 B point return To A point)；Third gear 23 connects second gear 46 by chain drive, and second gear 46 and the second synchronizing wheel 45 are set to together On one transmission shaft 47, therefore second gear 46 can be rotated synchronously with the second synchronizing wheel 45, and the second synchronizing wheel 45 is further through belt It is driven the first synchronizing wheel 42, and then front and back cam 41 is driven to rotate, front and back cam 41 abuts middle (center) bearing 33, and then with movable pendulum Swing (hinged support around swing arm bottom end) occurs for arm 31, and swing arm 31, which is swung forward, to be driven by front and back cam 41, swing arm Swinging backward is effect by spring force, under the collective effect of the two (front and back cam 41 and spring 36), swing arm upper end it is upper Bearing 32 is moved back and forth with swing arm, and then drives 3 front-rear reciprocation movement of iron plate, carries out moving material operation (vacuum slot 34 are moved to the point of the C in Fig. 3 from the A point in Fig. 3 again, to placing circuit board finished product 100 to the material conveying band on right side), Last zero load returns to A point, i.e. initial position from the C point in Fig. 3), simultaneously because upper bearing (metal) 32 is located at two of 3 both ends of iron plate In vertical chute (upper bearing (metal) 32 can move up and down relative to vertical chute), therefore upper bearing (metal) 32 can only push iron plate 3 to do water Square to movement, iron plate 3 can't be interfered in the movement of vertical direction；In addition one governor motor of the present apparatus can be completed entirely Portion's movement, component greatly reduce, and cost substantially reduces.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and structure, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and their equivalents.
