The branch mailbox feed mechanism of SMD light splitting machine
[technical field]
The utility model relates to a kind of SMD (surface mount device) light splitting machine, more particularly, relates to a kind of branch mailbox feed mechanism of SMD light splitting machine.
[background technology]
The SMD light splitting machine is a kind of equipment that the SMD material is classified according to its optical characteristics and electrology characteristic thereof, generally includes feeding system, detection system, branch mailbox feed system, hopper storage system.During work, the SMD material imports through feeding system, and system detects the classification back and delivered to by the branch mailbox feed system in the hopper of hopper storage system and store after testing.Wherein, the branch mailbox feed system adopts X, Y matrix platform feeding style usually, comprises the branch mailbox counting unit of band branch mailbox material blanking tube, the SMD material in the branch mailbox material blanking tube is imported the branch mailbox feed mechanism in the branch mailbox pipe of hopper storage system.
As shown in Figure 1, in the existing SMD light splitting machine, what the branch mailbox feed mechanism adopted is that three slide rails cooperate the ball spline pair as X, Y matrix platform, comprise by X-axis servo motor 11 driving X-axis that X-axis slide plate 13 is made vector shift along first slide rail 1 and second slide rail 2 in X-direction synchronously with the 12 X-axis slide plates 13 that drag; Also comprise by Y-axis servo motor 21 and drive Y-axis synchronously with the 22 branch mailbox counting units 30 that drag, branch mailbox counting unit 30 is made vector shift along the 3rd slide rail 3 in Y direction, the 3rd slide rail 3 is arranged on the X-axis slide plate 13, simultaneously the 3rd slide rail 3 is connected with the output shaft 21a of Y-axis servo motor 21 by ball spline secondary 40, with the perpendicularity of the output shaft 21a of assurance X-axis slide plate 13 and Y-axis servo motor.Determine X, the Y coordinate of corresponding branch mailbox pipe 50 on X, Y matrix platform in the hopper storage system, together control branch mailbox counting unit 30 by X-axis servo motor 11 and Y-axis servo motor 21 and move to corresponding X, Y coordinate, again the SMD material in the branch mailbox material blanking tube is imported in the corresponding branch mailbox pipe 50, thus the purpose of realization branch mailbox feeding.
When this branch mailbox feed mechanism has the following disadvantages:
1, branch mailbox counting unit is by Y-axis directly driving of band synchronously, and dynamic loading is bigger, has jiggly problem when braking at a high speed;
2, when the initial point of debugging X, Y matrix platform, it is original to need elder generation's location X-axis initial point to relocate Y-axis, debugs very inconvenience;
3, the ball spline that adopts is secondary because permissible accuracy is very high, and it is higher and fabrication cycle is long to make cost, and in later stage debugging and maintaining, it is very inconvenient to lay in these type of spare and accessory parts.
[utility model content]
The technical problems to be solved in the utility model is, drive the above-mentioned defective that X, Y matrix platform exist at the branch mailbox feed mechanism of SMD light splitting machine of the prior art owing to three slide rails that adopt cooperate the ball spline pair, the branch mailbox feed mechanism of the SMD light splitting machine that a kind of operation is more steady reliably, manufacturing cost is lower is provided.
The technical scheme that its technical problem that solves the utility model adopts is: the branch mailbox feed mechanism of constructing a kind of SMD light splitting machine, comprise first slide rail and second slide rail that are arranged on the workbench and are parallel to each other, X-axis by the X-axis driven by servomotor is with synchronously, by X-axis synchronously band drag and along first, the X-axis slide plate that two slide rails slide, be arranged on the workbench and with first, vertical the 3rd slide rail of two slide rails and be arranged on the X-axis slide plate and with first, the 4th slide rail that two slide rails are vertical, be arranged on slidably branch mailbox counting unit of X-axis slide plate upper edge the 4th slide rail, Y-axis by the Y-axis driven by servomotor is with synchronously, one end by Y-axis synchronously band drag and Y-axis guide post that the other end and described branch mailbox counting unit are slidingly connected described Y-axis guide post and first along the 3rd slide rail, two slide rails be arranged in parallel.
Further,
One end of described Y-axis guide post is fixed on the slide block, and described slide block slides to be provided with and to have described Y-axis to be with synchronously along described the 3rd slide rail and drags.
The other end of described Y-axis guide post is slidingly connected by 3 clamping guiding mechanisms and described branch mailbox counting unit.
Described 3 clamping guiding mechanisms comprise three clamping pulleys that are arranged on the branch mailbox counting unit, and described three clamp the both sides that pulleys are arranged on the Y-axis guide post.
Described clamping pulley is fixed in the chute of vertical Y axle guide post direction by removable securing member.
Implement the branch mailbox feed mechanism of SMD light splitting machine described in the utility model, has following beneficial effect: by the mobile basis that four one slide rails constitute X, Y matrix platform is set, wherein be provided with the X-axis slide plate on first and second slide rail by X-axis synchronously band drag and slide along Y direction, be provided with the Y-axis guide post on third and fourth slide rail by Y-axis synchronously band drag and slide along X-direction; Branch mailbox counting unit is arranged on the 4th slide rail on the X-axis slide plate, Y-axis guide post and branch mailbox counting unit are slidingly connected simultaneously, branch mailbox counting unit is slided along Y direction with the X-axis slide plate like this, and the Y-axis guide post is stirred branch mailbox counting unit in the 4th slide rail upper edge X-direction slip, thereby realizes the slip of branch mailbox counting unit in X, Y matrix platform.Because branch mailbox counting unit is to stir it by the Y-axis guide post to slide on the 4th slide rail when carrying out the X-axis displacement, rather than directly drag, so its dynamic loading is less by the synchronous band of Y-axis, more steady when braking at a high speed, reliable; Simultaneously, branch mailbox counting unit is along with the X-axis slide plate slides at the enterprising line linearity of first and second slide rail when carrying out the Y-axis displacement, and by being slidingly connected with the Y-axis guide post, make branch mailbox counting unit to slide along the Y-axis guide post, avoided employing ball spline pair, make manufacturing cost significantly reduce, make things convenient for the later maintenance maintenance.
Further, the Y-axis guide post being set is slidingly connected by 3 clamping guiding mechanisms and described branch mailbox counting unit.Wherein 3 clamping guiding mechanisms can be arranged on three clamping pulleys that are distributed in Y-axis guide post both sides on the branch mailbox counting unit.Like this, when debugging, only need to adjust three and clamp pulleys in the position of branch mailbox counting unit and adjust three and clamp between pulleys and the guide post and have the pretension chucking power, make between guide post and the clamping pulley very close to each other, just can adjust the relative position relation between Y-axis guide post and the branch mailbox counting unit, and can guarantee that branch mailbox counting unit can be along Y-axis guide post zero-clearance guiding movement, debugging is got up very convenient.
