Example 1
The main body of this embodiment is a circuit board transfer apparatus 100 for performing a transfer process of a circuit board to a turnover vehicle 140. Referring to fig. 1, fig. 2 and fig. 5, a schematic structural diagram of the circuit board transfer device provided in the present embodiment, a schematic structural diagram of the conveying mechanism and the positioning mechanism in the circuit board transfer device provided in the present embodiment, and a schematic structural diagram of the grasping mechanism in the circuit board transfer device provided in the present embodiment are shown.
In this embodiment, the circuit board transferring apparatus 100 specifically includes:
the conveying mechanism 110, the conveying mechanism 110 is used for bearing and conveying the circuit board;
a positioning mechanism 120, wherein the positioning mechanism 120 can contact and block the circuit board on the conveying mechanism 110, so as to position the circuit board to a position to be grabbed; and
and the grabbing mechanism 130 is used for grabbing and transferring the circuit board at the position to be grabbed.
In the technical solution provided in this embodiment, the positioning mechanism 120 is mainly provided to position the circuit board. The positioning mechanism 120 can contact and block the circuit board, so that the circuit board is located at a predetermined position to be grabbed. At this time, the grabbing mechanism 130 can perform grabbing actions to transfer the circuit board.
Because the circuit board at the position to be grabbed is in a relatively stable state, the position accuracy between the circuit board and the grabbing mechanism 130 can be effectively guaranteed, and the risk of grabbing failure conditions such as circuit board separation and the like of the grabbing mechanism 130 is effectively reduced.
The conveying mechanism 110 mainly refers to a member for conveying the circuit board, and may be any conveying mechanism 110 such as a conveyor belt or a conveyor roller. In the present embodiment, the conveying mechanism 110 is configured as a conveying belt. The position to be grasped refers to a position where a predetermined circuit board is to be grasped by the grasping mechanism 130. The grabbing mechanism 130 is used for grabbing the circuit board at the position to be grabbed, and may include a grabbing end 131 such as a suction nozzle and a mechanically movable clamping jaw.
In the present embodiment, in order to improve the transfer efficiency of the whole circuit board transfer device 100, a plurality of positioning mechanisms 120 are provided to perform positioning work synchronously. In detail, in the present embodiment, the positioning mechanism 120 at least includes a positioning state and a release state, the number of components of the positioning mechanism 120 is multiple, and the multiple positioning mechanisms 120 are sequentially arranged along the conveying path of the conveying mechanism 110. It should be noted that, here, the positioning state is a state in which the designated positioning mechanism 120 can contact and block the circuit board, and the release state is a state in which the designated positioning mechanism 120 is retracted from the circuit board on the conveying mechanism 110, and when the positioning mechanism 120 is in the release state, the circuit board can pass through the positioning mechanism 120 without acting on the positioning mechanism 120.
In this embodiment, the number of the positioning mechanisms 120 is two, and when the circuit board transfer device 100 is started, one positioning mechanism 120 is in a positioning state, and the other positioning mechanism 120 is in a release state. In this case, the circuit board will finally move to the positioning mechanism 120 in the positioning state, and the positioning mechanism 120 will complete its positioning, and then the circuit board is grabbed by the grabbing mechanism 130, and the positioning mechanism 120 is also switched from the positioning state to the release state. While the positioning mechanism 120 is switched from the positioning state to the release state, the other positioning mechanism 120 is correspondingly switched from the release state to the positioning state, so that it can position the next circuit board conveyed by the conveying mechanism 110. In the process that the rest of the positioning mechanisms 120 are switched from the release state to the positioning state, the grabbing mechanism 130 can grab the circuit board which has been positioned and is located at the position to be grabbed, and complete the transfer of the circuit board. By the arrangement, the grabbing and transferring actions of the grabbing mechanism 130 and the action of the state change of the positioning mechanism 120 can be synchronously performed, and the transferring efficiency of the circuit board is further improved. In addition, the implementer may flexibly adjust the specific number of the positioning mechanisms 120 according to the actual situation, for example, the positioning mechanisms 120 are arranged in three, four or five groups, which is not particularly limited in the present application.
After the circuit board is blocked by the positioning part 121, the conveying mechanism 110 still applies a certain driving force to the circuit board. Taking the conveying belt adopted in this embodiment as an example, after the positioning portion 121 contacts with the circuit board, the belt of the conveying belt still applies a friction force to the circuit board, which makes the circuit board have a moving tendency, which easily causes the circuit board to turn over and affects the grabbing of the grabbing mechanism 130. Especially, when the gripping mechanism 130 is a vacuum gripping mechanism 130 having a suction nozzle, the friction force is very likely to affect the contact effect between the suction nozzle and the outer surface of the circuit board, thereby reducing the gripping reliability of the gripping mechanism.
Therefore, referring to fig. 2 again, in the present embodiment, the positioning mechanism 120 at least includes two positioning portions 121 arranged at intervals along the conveying path of the conveying mechanism 110; when the circuit board is positioned, the positioning portions 121 on the two sides can move towards each other to clamp the circuit board therebetween and drive the circuit board to be separated from the conveying mechanism 110, so that the circuit board is positioned to a position to be grabbed. More specifically, in this embodiment, after the positioning portions 121 on the two sides clamp the circuit board, the circuit board is lifted to a position higher than the conveying surface of the conveying belt by a certain distance, so as to separate the circuit board from the conveying belt. Through setting up as above, can avoid the circuit board to receive conveying mechanism 110's influence, and then promote and snatch stability.
It should be noted that the two side positioning portions 121 clamp the circuit board therebetween and drive the circuit board to be separated from the conveying mechanism 110, and are not limited to what is shown in this embodiment: the positioning portions 121 on both sides lift the clamped circuit board by a certain height. The two side positioning portions 121 can move in the lateral direction of the conveying mechanism 110 after clamping the circuit board, so that the circuit board is separated from the conveying mechanism 110.
In addition, the two side positioning portions 121 may lift the clamped circuit board to any height, for example, the height difference between the lifted circuit board and the conveying mechanism 110 is 1mm, 2mm, 3mm, 5mm or 10mm, and the like, and the implementer may specifically select the circuit board according to the actual situation.
As to how the positioning mechanism 120 is switched between the positioning state and the releasing state, in the embodiment, the positioning mechanism 120 includes a frame and a number of first driving members 122 corresponding to the number of positioning portions 121, each of the first driving members 122 has a first fixed end and a first movable end, the first fixed end is connected to the frame, and the positioning portions 121 are connected to the first movable end, and the first fixed end and the first movable end are capable of relatively moving in a first direction away from the conveying mechanism 110. The first driving element 122 is specifically a first cylinder, and two ends of the first cylinder in the telescopic direction respectively form a first fixed end and a first movable end. Upon activation of the first cylinder, the positioning mechanism 120 switches between the positioning state and the release state.
In detail, in the embodiment, when the positioning portion 121 is located above the conveying mechanism 110 and keeps a preset small distance from the conveying mechanism 110 under the action of the first air cylinder, the circuit board contacts with the positioning portion 121 along with the conveying of the conveying mechanism 110 and is blocked by the positioning portion 121, and at this time, the positioning mechanism 120 is in a positioning state. When the positioning portion 121 is located above the conveying mechanism 110 and keeps a preset large distance from the conveying mechanism 110 under the action of the first cylinder, the circuit board passes through the lower portion of the positioning portion 121 along with the conveying of the conveying mechanism 110, and the positioning portion 121 avoids the circuit board. At this point, the positioning mechanism 120 is in the released state.
In addition, for the opposite movement of the positioning portions 121 on both sides, in the present embodiment, in the positioning mechanism 120, there is one positioning portion 121 connected to the first movable end through the second driving element 123, the second driving element 123 includes a second fixed end and a second movable end capable of moving relatively along a second direction parallel to the conveying direction of the conveying mechanism 110, the second fixed end is connected to the first movable end, and the second movable end is connected to the positioning portion 121. Wherein, the second driving member 123 is specifically a second cylinder, and both ends of the second cylinder in the telescopic direction respectively constitute a second fixed end and a second movable end. Referring to fig. 2, a direction indicated by an arrow in fig. 2 is a moving direction of the positioning portion 121 during clamping, in this embodiment, only one of the two positioning portions 121 is connected to the first movable end of the first cylinder through the second driving member 123, that is, when the two positioning portions 121 move towards each other, one of the two positioning portions is in a moving state, and the other positioning portion is in a stationary state. The operator may set both side positioning portions 121 to be movable toward each other, and the present application is not limited to this.
It should be noted that, in this embodiment, a first cylinder is specifically used as the first driving element 122, and a second cylinder is used as the second driving element 123, and the implementer may also select another form of linear driving mechanism to partially or completely replace the first driving element 122 and the second driving element 123, which is not particularly limited in this application.
In a positioning state, the distance between the positioning portions 121 on both sides needs to be matched with the size of the circuit board, so that the positioning portions 121 on both sides can clamp the circuit board and drive the circuit board to move. The operator can adjust the distance between the both-side positioning portions 121 by adjusting the stroke of the cylinder rod in the second cylinder. However, it is obvious that the adjustment accuracy of the stroke of the cylinder rod is limited and the adjustment is inconvenient, and it is difficult or impossible to achieve continuous and stepless adjustment of the distance. In a special case, there may occur a case where the positioning portions 121 of both sides are not effectively brought into contact with the circuit board, or the positioning portions 121 of both sides are excessively brought into contact with the circuit board to excessively press the circuit board.
In this embodiment, referring to fig. 3 and 4, the positioning portion 121 includes a first wedge 124a, a second wedge 124b, and a clamping portion 128, a first wedge surface of the first wedge 124a is in sliding contact with a second wedge surface of the second wedge 124b, and a relative position between the first wedge 124a and the second wedge 124b can be locked, the clamping portion 128 is disposed on the first wedge 124a and is used for contacting the circuit board; in the positioned state, the first wedge 124a and the second wedge 124b of the both-side positioning portion 121 can slide relative to each other to adjust the distance D between the both-side clamping portions 128.
Because the clamping portion 128 is formed on the first wedge 124a, the first wedge and the second wedge slide to drive the clamping portions 128 on both sides to move towards each other, so as to achieve fine adjustment of the distance between the two sides, and under some circumstances, the adjustment of the stroke of the cylinder rod in the second cylinder can be replaced by the first wedge and the second wedge, thereby avoiding the situation that the positioning portions 121 on both sides are not effectively contacted with the circuit board, or the positioning portions 121 on both sides are excessively contacted with the circuit board to extrude the circuit board.
Further, the relative sliding between the first wedge surface and the second wedge surface allows the continuous and stepless adjustment of the pitch between the both-side clamping portions 128. The continuous, stepless adjustment of the spacing here means that the range of variation of the spacing between the two side clamping portions 128 is continuous.
Regarding the locking manner between the first wedge 124a and the second wedge 124b, in this embodiment, the positioning portion 121 further includes a slot 125, the slot 125 extends from a surface of the first wedge 124a opposite to the first wedge surface and extends to the first wedge surface, the positioning portion 121 further includes a plug 126 fixedly formed on the second wedge 124b, the plug 126 extends from one end of the slot 125 formed on the first wedge surface to the other end of the slot 125, a position of the plug 126 extending out of the first wedge 124a is connected with a limiting member 127 capable of moving and locking along an extending direction of the plug 126, and the limiting member 127 is used for abutting against the first wedge 124 a. When the limiting member 127 abuts against the first wedge 124a, the limiting member 127 and the plug 126 apply a certain pressure to the first wedge 124a and the second wedge 124b, so as to increase the friction force between the first wedge surface and the second wedge surface, and further keep the first wedge surface and the second wedge surface in a relatively static state. Other locking structures may be selected by the practitioner to achieve locking between the first wedge 124a and the second wedge 124b, and this is not a particular limitation in this application.
More specifically, the stop member 127 is a nut that is screwed onto a thread formed at an end of the plug 126, and the nut can adjust the position on the plug 126 by its own screwing action, thereby keeping contact with the first wedge 124 a.
The circuit board transfer device 100 provided by the embodiment is mainly used for transferring circuit boards between the conveying mechanism 110 and the turnover vehicle 140. The turnover vehicle 140 is provided with placing positions for placing circuit boards, and the placing positions comprise qualified placing positions and unqualified placing positions. Meanwhile, the circuit board transfer device 100 further includes a scanning mechanism for acquiring quality information of the circuit board and transmitting the quality information to the grasping mechanism 130, and the grasping mechanism 130 is used for placing the circuit board in a corresponding placement position according to the quality information. Here, the quality information at least includes whether the circuit board is a qualified circuit board or an unqualified circuit board, and the grasping mechanism 130 places the qualified circuit board in the qualified placement position and places the unqualified circuit board in the unqualified placement position after acquiring the quality information of the circuit board.
In addition, in the embodiment, each circuit board is provided with a scanning code including its own quality information, the scanning mechanism is specifically a scanning gun (not shown), a scanning range of the scanning gun overlaps with a conveying path of the conveying mechanism 110, and an overlapping position of the scanning gun and the conveying path is located at an upstream of the positioning mechanism 120, so that the scanning codes on the circuit boards are identified one by one.
