The following describes specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.
An embodiment of the present utility model is to provide a suction nozzle device, as shown in fig. 1 to 3, including a variable-pitch mechanism 1, a first lift suction nozzle 2, and a second lift suction nozzle 4; the first lifting suction nozzles 2 are arranged in a plurality, and the first lifting suction nozzles 2 are arranged on the variable-pitch mechanism 1 side by side and are in sliding fit with the variable-pitch mechanism 1 along the arrangement direction; the variable-pitch mechanism 1 comprises a cam shaft 11, wherein the cam shaft 11 is provided with a plurality of guide grooves which are in sliding fit with the first lifting suction nozzles 2 in a one-to-one correspondence manner so as to adjust the distance between the first lifting suction nozzles 2 when the cam shaft 11 rotates; the second lifting suction nozzle 4 is fixedly arranged on the variable-pitch mechanism 1 and is positioned between any two adjacent first lifting suction nozzles 2.
The suction nozzle device provided by the embodiment breaks away from the traditional mode of realizing suction nozzle pitch variation through the belt transmission mechanism, and adjusts the distance between the first lifting suction nozzles 2 through the sliding fit of the guide grooves on the cam shaft 11 and the first lifting suction nozzles 2, so that the pitch variation precision is ensured, and the problem of poor pitch variation precision caused by loosening of the synchronous belt and the phenomenon of powder falling of the synchronous belt are fundamentally solved; secondly, the first lifting suction nozzles 2 can be stopped at any position by controlling the rotation angle of the cam shaft 11, so that the distance between two adjacent first lifting suction nozzles 2 can be adjusted steplessly, and the compatibility is good; again, the length of the cam shaft 11 is easy to adjust, the number of the guide grooves on the cam shaft is also easy to adjust, and more first lifting suction nozzles can be adapted according to the needs; finally, the second lifting suction nozzle 4 does not need to be matched with the guide groove on the cam shaft 11, the distance between the second lifting suction nozzle and the first lifting suction nozzle can be adjusted through the movement of each first lifting suction nozzle, and the structure of the second lifting suction nozzle 4 is simpler and the cost is saved.
In some embodiments, as shown in fig. 1, the number of first lifting suction nozzles 2 on both sides of the second lifting suction nozzle 4 is the same.
In use, the second lifting suction nozzles 4 are fixed along the arrangement direction of the plurality of first lifting suction nozzles 2, and the first lifting suction nozzles 2 positioned at both sides of the second lifting suction nozzles 4 move along the track of the guide groove along with the rotation of the cam shaft 11.
The structure of the camshaft 11 is specifically described below:
the extending track of each guiding groove on the cam shaft 11 is related to the moving distance of each first lifting suction nozzle 2 after the cam shaft 11 rotates by a unit angle, so that a user can design the extending track of each guiding groove according to the moving distance of each first lifting suction nozzle 2 required to drive a product.
In some embodiments, the cam shaft 11 is provided with a plurality of guide grooves, and the plurality of guide grooves are distributed at intervals along the axial direction of the cam shaft 11, and each guide groove is in sliding fit with one first lifting suction nozzle 2 so as to adjust the distance between the first lifting suction nozzles 2.
When the lifting suction nozzle is used, the rotation angle of the cam shaft 11 can be controlled to enable each lifting suction nozzle 2 to be static at different positions, so that adjustment of different distances is realized. Every time the cam shaft 11 is stationary at an angle, the first lifting nozzle 2 will stop at a certain mating section of the guide slot. Therefore, each guide groove can be provided with a plurality of matching sections, such as two, three, four and the like, and the first lifting suction nozzle 2 is static at different matching sections and corresponds to different distance parameters.
The specific explanation will be given taking as an example that each guide groove has three mating sections. As shown in fig. 5 and 6, the three mating segments are a first mating segment 1111, a second mating segment 1112, and a third mating segment 1113 located between the first mating segment 1111 and the second mating segment 1112, the first mating segment 1111 and the second mating segment 1112 being located at both ends of the guide slot, respectively;
the distance between the first mating segments 1111 of the two adjacent guide grooves is a first distance, the distance between the second mating segments 1112 of the two adjacent guide grooves is a second distance, the distance between the third mating segments 1113 of the two adjacent guide grooves is a third distance, the first distance is greater than the third distance, and the third distance is greater than the second distance.
When the first elevation suction nozzle 2 is stationary at the first fitting section 1111, the distance between two adjacent first elevation suction nozzles 2 is maximized; when the first lifting suction nozzles 2 are stationary at the second fitting section 1112, the distance between two adjacent first lifting suction nozzles 2 is the smallest; when the first lift nozzle 2 is stationary at the third mating segment 1113, the distance between two adjacent first lift nozzles 2 tends to be intermediate.
According to the actual production requirement, personnel can also divide fourth cooperation section, fifth cooperation section etc. in the guiding groove. When there are an infinite number of mating segments, the guide slot can be considered to be made up of individual mating segments. Specifically, the plurality of guide grooves on the camshaft 11 may be divided into two groups, the number of the guide grooves in the two groups being the same, and the two groups of guide grooves being symmetrically arranged about a first plane, which is a cross section of the camshaft 11.
Because the two groups of guide grooves are symmetrically arranged about the first plane, and each guide groove extends spirally around the axis of the cam shaft 11, the two guide grooves symmetrical about the first plane have different spiral directions, and when the cam shaft 11 rotates, the two first lifting suction nozzles 2 correspondingly matched with the two guide grooves are close to or far away from each other.
Of course, the plurality of guide grooves may be divided into three groups, four groups, or the like as needed.
In any one set of guide grooves: the rotation direction of each guide groove may be the same, and the pitch of each guide groove gradually decreases in a direction gradually approaching the first plane.
The arrangement can ensure that when the cam shaft 11 rotates, the first lifting suction nozzles 2 matched with the same group of guide grooves are gradually close to each other or gradually far away from each other, so that the orderly adjustment of the distance between the first lifting suction nozzles 2 is ensured, and the movement process is smooth without blocking.
The number of the guide grooves in each set of the guide grooves may be one, two, three, four, etc., and the following embodiments will be specifically described by taking the structure shown in fig. 4 as an example.
As shown in fig. 4, the plurality of guide grooves on the camshaft 11 are divided into two groups, each group including three guide grooves, six guide grooves in total, the six guide grooves being, from left to right, a first guide groove 111, a second guide groove 112, a third guide groove 113, a fourth guide groove 114, a fifth guide groove 115, and a sixth guide groove 116, respectively. As shown in fig. 5 and 6, three auxiliary lines are introduced, a first auxiliary line 5, a second auxiliary line 6 and a third auxiliary line 7. When each first lifting suction nozzle 2 slides to the first end of each guide groove, the connecting line of the position where each first lifting suction nozzle 2 is matched with each guide groove can be regarded as a first auxiliary line 5; when each first lifting suction nozzle 2 slides to the second end of each guide groove, the connection line of the matching position of each first lifting suction nozzle 2 and each guide groove can be regarded as a third auxiliary line 7; when each first elevating suction nozzle 2 slides between the first end and the second end of each guide groove, the connection line where each first elevating suction nozzle 2 is engaged with each guide groove can be regarded as the second auxiliary line 6.
The intersection between the first auxiliary wire 5 and the respective guide groove may be regarded as a first fitting section 1111, the intersection between the second auxiliary wire 6 and the respective guide groove may be regarded as a third fitting section 1113, and the intersection between the third auxiliary wire 7 and the respective guide groove may be regarded as a second fitting section 1112.
As the pitch of each guide groove gradually decreases in a direction gradually approaching the first plane, it can be seen in conjunction with fig. 5 and 6 that the distance between two adjacent guide grooves at the first auxiliary line 5 is the largest (the distance between two adjacent first lifting suction nozzles 2 is the largest); the distance between two adjacent guide grooves at the third auxiliary line 7 is the smallest (the distance between two adjacent first elevating suction nozzles 2 is the smallest); the distance between the adjacent two guide grooves at the second auxiliary line 6 tends to be between the maximum distance and the minimum distance (the distance between the adjacent two first elevating suction nozzles 2 tends to be between the maximum distance and the minimum distance).
In specific use, the detection of two specifications of incoming products can be realized through the cam shaft 11. When the A product and the B product are adsorbed, the first lifting suction nozzle 2 reaches the position where the guide groove intersects with the first auxiliary line 5, and the distance between the first lifting suction nozzles 2 is L 1 The position is shown in fig. 7 (where the first auxiliary line 5 is blocked). When the product A is placed, the initial position of the cam shaft 11 matched with the first lifting suction nozzle 2 is the position of the first auxiliary line 5, the matched position of the cam shaft 11 and the first lifting suction nozzle 2 slides from the position of the first auxiliary line 5 to the position of the third auxiliary line 7, namely, the first lifting suction nozzle 2 reaches the position where the guide groove intersects with the third auxiliary line 7, and the distance between the first lifting suction nozzle 2 is L 3 The position is shown in fig. 8 (in which the third auxiliary line 7 is blocked). When the product B is adsorbed, the initial position of the cam shaft 11 and the first lifting suction nozzle 2 is the position of the first auxiliary line 5, the matched position slides from the position of the first auxiliary line 5 to the position of the second auxiliary line 6, namely, the first lifting suction nozzle 2 reaches the position where the guide groove intersects with the second auxiliary line 6, and the distance between the first lifting suction nozzles 2 is L 2 The position is shown in fig. 9 (in which the second auxiliary line 6 is blocked).

The structure of the second elevating suction nozzle 4 is specifically described as follows:
the second lifting suction nozzle 4 has a similar structure to the first lifting suction nozzle 2. Since the second lifting suction nozzle 4 is fixedly mounted on the variable-pitch mechanism 1, it does not need to be matched with the guide groove on the cam shaft 11 or slidingly matched with the variable-pitch mechanism 1. As shown in fig. 12 and 14, therefore, the second lifting nozzle 4 differs from the first lifting nozzle 2 in that: the second lifting nozzle is not provided with a slider 211 (for sliding engagement with the slide rail 122 on the pitch change mechanism 1) and a protruding shaft 212 (for sliding engagement with the guide groove extending into the guide groove).
When the pitch mechanism 1 comprises the fixed seat 12, the second lifting suction nozzle 4 can be fixedly arranged on the fixed seat 12 through a connecting piece such as a screw.
In some embodiments, as shown in fig. 15 and 16, the nozzle device further includes an electrical box assembly 3 for mounting cables and air paths. The cable can supply power for the variable-pitch mechanism 1 and each first lifting suction nozzle 2, and the air circuit can supply air for the first lifting suction nozzles 2.
In some embodiments, as shown in fig. 15, the electrical box assembly 3 includes a drag chain 31, a pressing plate 32, an electrical box 33, and a fixing plate 34, the drag chain 31 is mounted on the electrical box 33 through the fixing plate 34, the drag chain 31 forms a channel for accommodating a cable and an air path, the pressing plate 32 is mounted on the fixing plate 34 and is located at an end of the drag chain 31, and the pressing plate 32 is used for folding the cable and the air path on the fixing plate 34.
The electrical box assembly 3 is designed with the drag chain 31, which not only can protect the cable from being broken and scratched in the bending process, but also can reduce the risk of falling dust in the movement.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
