Description

Technical Field

[0001] The utility model relates to the technical field of appearance detection, and particularly relates to a multi-faceted appearance detection nozzle mechanism, a handling device and a feeding device. Background Art

[0002] During the product appearance detection process, a handling device is usually used to handle the product to realize the automatic detection of the product appearance. For some small-sized products, they are usually arranged in an array on a tray to facilitate the orderly flow of the products, and it is easier for the handling device to obtain the product position for handling.

[0003] Existing handling devices usually include a nozzle mechanism. A number of nozzle components are arranged side by side in the nozzle mechanism to correspond to a plurality of products arranged side by side in the tray one by one, so that the nozzle mechanism can suck a row of products in the tray at a time, improving the handling efficiency. In addition, the handling device is also provided with a variable pitch structure. When the nozzle mechanism is transferred to the detection station, the variable pitch structure will adjust the distance between the nozzle components to adapt it to the detection station. However, the existing variable pitch structure usually guides the variable pitch through a guide groove. For example, Chinese invention patent CN202210916777.7 discloses a groove body variable pitch device. Using the variable pitch structure in the above form, its structure is complex, it occupies a large space, and the disassembly and assembly are cumbersome, which is not conducive to cost reduction and efficiency improvement.

[0004] Therefore, it is necessary to improve the existing technology to overcome the defects in the existing technology. Summary of the Utility Model

The mounting shaft 141 is fixed to the mounting base 110 and passes through several nozzle assemblies 120. There are several reset springs 142, and they abut between adjacent second nozzle assemblies 120b; wherein, when the variable pitch cylinder 130 drives the first nozzle assembly 120a to approach and push the second nozzle assembly 120b, the second nozzle assemblies 120b approach each other and compress the reset spring 142, and when the variable pitch cylinder 130 drives the first nozzle assembly 120a to move away from the second nozzle assembly 120b, the second nozzle assemblies 120b are adapted to move away from each other under the elastic return action of the reset spring 142.

[0044] With the above structure, when the pitch-changing cylinder 130 drives the first nozzle assembly 120a to approach and push the second nozzle assembly 120b, the second nozzle assemblies 120b approach each other and compress the return spring 142. When the pitch-changing cylinder 130 drives the first nozzle assembly 120a away from the second nozzle assembly 120b, the second nozzle assemblies 120b are adapted to move away from each other under the resilience of the return spring 142. The reset assembly 140 cooperates with the pitch-changing cylinder 130 to realize the switching of a plurality of nozzle assemblies 120 between the retracted state and the deployed state. The rotation structure is simple, the disassembly and assembly are convenient, the occupied space is small, which is beneficial to cost reduction and efficiency improvement.

[0045] Further, the mounting seat 110 has opposite first mounting surface 111 and second mounting surface 112 in its width direction.

The nozzle assembly 120 is fixed to the first slider 152. The number of the first sliders 152 is multiple and corresponds to the nozzle assemblies 120 one by one. Preferably, the number of the slide rail assemblies 150 is two groups and they are arranged at intervals in the vertical direction. The parts of the nozzle assembly 120 near the upper side and the lower side are respectively arranged on different slide rail assemblies 150, so that the installation and sliding of the nozzle assembly 120 are more reliable. The reset assembly 140 is located between the two groups of slide rail assemblies 150 to correspond to the part of the nozzle assembly 120 near the middle. The number of the reset assemblies 140 is two groups and they are arranged at intervals in the vertical direction to ensure the reliable reset of the nozzle assembly 120.

[0046] Further, a first avoidance hole 113 is formed through the mounting base 110 in its width direction, and the first avoidance hole 113 extends along the length direction of the mounting base 110 towards both sides of the mounting base 110. The variable pitch cylinder 130 is a linear cylinder arranged along the length direction of the mounting base 110, and it is fixed to the second mounting surface 112 of the mounting base 110, making the installation of the variable pitch cylinder 130 more convenient and having a large moving space. The number of variable pitch cylinders 130 is two, and the output ends of the two variable pitch cylinders 130 are respectively in transmission cooperation with different first nozzle assemblies 120a through the first avoidance hole 113.

A plurality of nozzle assemblies 120 are in an unfolded state in response to the variable pitch cylinder 130 switching to the extended state, and are in a retracted state in response to the variable pitch cylinder 130 switching to the retracted state. When the variable pitch cylinder 130 is in the extended state, the distance between adjacent two nozzle assemblies 120 is the same, and when the variable pitch cylinder 130 is in the retracted state, the distance between adjacent two nozzle assemblies 120 is also the same.

[0047] Further, as shown in reference to Figures 3 to 5 shown, a pushing member 170 is provided on the second nozzle assembly 120b adjacent to the first nozzle assembly 120a, and the pushing member 170 protrudes from the side of the second nozzle assembly 120b facing the first nozzle assembly 120a; and / or a pushing member 170 protrudes from the side of the first nozzle assembly 120a facing the second nozzle assembly 120b. When the first nozzle assembly 120a approaches the second nozzle assembly 120b, the first nozzle assembly 120a is driven by the pushing member 170 to maintain a preset distance between the first nozzle assembly 120a and the second nozzle assembly 120b, and the pushing member 170 is adapted to transmit a thrust of approaching each other to the second nozzle assembly 120b.

[0048] In this embodiment, the pushing member 170 is specifically provided on the second nozzle assembly 120b, and the pushing member 170 is a threaded member threadedly connected to the second nozzle assembly 120b. The axial direction of the pushing member 170 is parallel to the length direction of the mounting base 110. The protruding amount of the pushing member 170 can be adjusted as needed, so as to adjust the distance between the first nozzle assembly 120a and the second nozzle assembly 120b, so as to ensure that the distances between adjacent nozzle assemblies 120 are all kept consistent after the nozzle assemblies 120 are retracted.

[0049] Preferably, a plurality of limiting members 180 are provided on the mounting base 110. The limiting members 180 correspond to the second nozzle assemblies 120b. When the first nozzle assembly 120a moves away from the second nozzle assembly 120b, the return spring 142 is adapted to push the second nozzle assembly 120b against the limiting member 180, ensuring that the distances between adjacent second nozzle assemblies 120b are all kept consistent, while the distance between the first nozzle assembly 120a and the second nozzle assembly 120b can be achieved by adjusting the telescopic stroke of the distance-changing cylinder 130.

[0050] Further, the number of the second nozzle assemblies 120b is N, N≥3 and is an odd number. In this embodiment, the number of the second nozzle assemblies 120b is specifically three. The pushing member 170 is arranged on the second nozzle assembly 120b adjacent to the first nozzle assembly 120a, and the limiting member 180 corresponds to the second nozzle assembly 120b provided with the pushing member 170 one by one. In addition, when the number of the second nozzle assemblies 120b is an odd number, the second nozzle assembly 120b in the middlemost position can be fixed relative to the mounting base 110.

[0051] Further, the nozzle assembly 120 includes a mounting block 121, a nozzle member 122 and a lifting cylinder 123.

The nozzle member 122 is slidably mounted on the mounting block 121 in the vertical direction. The lifting cylinder 123 is mounted on the mounting block 121 and is in transmission connection with the nozzle member 122. The lifting cylinder 123 is adapted to drive the nozzle member 122 to lift in the vertical direction, so as to facilitate each nozzle member 122 to independently pick and place products. A convex portion 1212 is provided on the mounting block 121 corresponding to the limiting member 180. The convex portion 1212 extends from the first avoidance hole 113 to the second mounting surface 112 and is oppositely arranged with the limiting member 180 in the length direction of the mounting base 110. When the return spring 142 pushes the mounting block 121, the convex portion 1212 is adapted to abut against the limiting member 180.

[0052] The movement process of the suction nozzle mechanism 100 of the utility model is as follows: when it is necessary to switch a plurality of suction nozzle assemblies 120 from an extended state to a retracted state, the variable distance cylinder 130 switches from an extended state to a retracted state. During this process, the two variable distance cylinders 130 respectively pull different first suction nozzle assemblies 120a to move toward each other, thereby pushing the adjacent second suction nozzle assemblies 120b to gather toward the middle second suction nozzle assembly 120b, and gradually compressing the return spring 142. When the variable distance cylinder 130 is in a retracted state, a plurality of suction nozzle assemblies 120 switches to the retracted state; when it is necessary to switch several suction nozzle assemblies 120 to the extended state, the variable distance cylinder 130 switches from the retracted state to the extended state. During this process, the two variable distance cylinders 130 respectively push different first suction nozzle assemblies 120a to move backwards to gradually release the limit on the second suction nozzle assembly 120b. The second suction nozzle assembly 120b is gradually expanded to the preset position under the push of the return spring 142. When the variable distance cylinder 130 is in the extended state, several suction nozzle assemblies 120 switch to the extended state.

The material storage mechanism 420 stores a material tray 450 containing products, and the transfer mechanism 440 is suitable for moving back and forth between the material storage mechanism 420 and the positioning mechanism 430 along a second horizontal direction perpendicular to the first horizontal direction, and lifting and lowering along the vertical direction to take and put the material tray 450. When the transfer mechanism 440 is directly below the material storage mechanism 420, the transfer mechanism 440 is suitable for rising and receiving the material tray 450 flowing out of the material storage mechanism 420. When the transfer mechanism 440 is directly below the positioning mechanism 430, the transfer mechanism 440 is suitable for rising and moving the material tray 450 to the positioning mechanism 430, ensuring that the conveying device 200 accurately and reliably conveys the products on the material tray 450.

[0055] Further, refer to Figure 7 and Figure 8As shown, the material storage mechanism 420 includes a first stacking component 421 and a second stacking component 422.

The second support structure 4222 is a flipping block, which is pivotally mounted on the first housing 4211. When the tray 450 is moved into the second housing 4221 from the lower side of the second housing 4221, the second support structure 4222 can be flipped upward to avoid interference. And after the tray 450 is no longer in contact with the second support structure 4222, the second support structure 4222 flips downward to reset and reliably support the tray 450. The number of the second support structures 4222 is also two, and they are arranged oppositely on both sides of the second housing 4221.

The second sliders 4232 are fixed on both brackets 411, and each bracket 411 is provided with a plurality of second sliders 4232 at intervals along the second horizontal direction. The two second slide rails 4231 are respectively slidably connected to the second sliders 4232 on different brackets 411. By adopting the above structure, the first housing 4211 and the second housing 4221 can be moved along the second horizontal direction as needed, so as to facilitate the loading and unloading of the tray 450.

[0059] Preferably, a push-pull plate 4234 is fixed between the two mounting plates 4233. The push-pull plate 4234 is located at the end of the second slide rail 4231. A handle 4235 is provided on the push-pull plate 4234. The operator can push and pull the first housing 4211 and the second housing 4221 by holding the handle 4235, which is more convenient to operate.

[0060] Further, referring to Figure 9 As shown, the transfer mechanism 440 includes a transverse movement module 441, a lifting module 442 connected to the transverse movement module 441, and a carrier 443 connected to the lifting module 442. The transverse movement module 441 is adapted to drive the carrier 443 to move along the second horizontal direction. The lifting module 442 is adapted to drive the carrier 443 to lift and lower along the vertical direction. The carrier 443 is adapted to support the tray 450. Preferably, a plurality of vacuum suction cups 444 are provided on the top surface of the carrier 443 to cooperate with the adsorption of the tray 450 to improve the reliability during the transfer process.

[0061] Further, referring to Figure 10 andFigure 11 As shown, the positioning mechanism 430 includes a positioning plate 431 and a third support structure 432. The two sides of the positioning plate 431 are respectively disposed on different brackets 411.

The positioning plate 431 is recessed inward from its top surface to form a positioning groove 4312. The positioning groove 4312 surrounds the outer periphery of the second avoidance hole 4311. The outer contour of the tray 450 is adapted to the inner contour of the positioning groove 4312. When the stage 443 is directly below the positioning plate 431, it is adapted to move upward under the drive of the lifting module 442, and then embed and position the tray 450 in the positioning groove 4312. The second avoidance hole 4311 is adapted to avoid the storage area of the tray 450 where products are stored, so as not to hinder the handling device 200 from handling products.

[0062] The third support structure 432 is located below the positioning plate 431. The third support structure 432 is similar to the first support structure 4212. When it is necessary to load the tray 450 into the positioning groove 4312, it is adapted to move along the first horizontal direction to the lower part of the notch of the positioning groove 4312 to support the tray 450, so that the tray 450 is vertically limited between the bottom of the positioning groove 4312 and the third support structure 432.
