Description

Technical Field

[0001] This utility model relates to the field of automated tooling production equipment technology, and in particular to a visual positioning adjustment device. Background Technology

[0002] In the automated production and packaging process of pencils such as eyebrow pencils and pencils, labels need to be affixed to the pencil casings. However, as the pencils are transported along the conveyor line, the markings on them are not aligned in the same direction. Before labeling, all the markings need to be aligned to the same direction. After unifying the direction, the pencils are transferred to the labeling station, where they can be labeled more uniformly.

[0003] The traditional method is to manually rotate the pen or slightly rotate each pen individually with a brush to ensure that the pen markings are aligned in a uniform direction. However, this method is inefficient and wastes a lot of manpower and resources, making it difficult to achieve fully automated positioning and adjustment. Utility Model Content

[0004] Purpose of the utility model: To address the problems existing in the prior art, this utility model provides a visual positioning adjustment device that uses a suction cup to perform adsorption and gripping, a clamping and rotating mechanism to achieve pen clamping and rotation, and a camera to achieve visual positioning, thereby realizing fully automatic visual positioning adjustment.

[0005] Technical Solution: This utility model provides a visual positioning adjustment device, including a frame and a left-right sliding assembly mounted on the frame. At least one set of suction gripping components is slidably mounted on the left-right sliding assembly. A clamping rotation assembly is also mounted on the frame. A set of cameras is also mounted on the frame below the clamping rotation assembly, with the cameras facing the product clamped on the clamping rotation assembly. The suction gripping assembly grips the product on the conveyor line and moves towards the clamping rotation assembly under the action of the left-right sliding assembly. After the clamping rotation assembly clamps the product, the camera is activated. Based on the image captured by the camera, the product is rotated by the clamping rotation assembly until it is aligned with the direction. After rotation, the suction gripping assembly grips the product and moves it towards the downward direction under the action of the left-right sliding assembly.

[0006] Furthermore, the adsorption and gripping assembly includes multiple sets of suction cups, each set of suction cups having at least one suction cup, and the suction cup sets are connected to a vacuum generator; each set of suction cups is connected to a sliding seat via a suction cup connecting shaft, the sliding seat of the leftmost suction cup set is connected to a fixed plate, and the sliding seats of the remaining suction cup sets are slidably mounted on a pair of connecting shafts via linear bearings, and connected to another fixed plate via the connecting shafts, both of which are connected to a longitudinal sliding assembly.

[0007] Furthermore, the longitudinal sliding assembly includes a guide rail fixing seat, a lifting seat, a pair of longitudinal guide rails, and a lifting cylinder. The fixing plate is fixed on the lifting seat, the pair of longitudinal guide rails are vertically arranged on the guide rail fixing seat, the lifting seat and the pair of longitudinal guide rails are connected to the lifting seat, and the guide rail fixing seat is arranged on the left and right sliding assembly.

[0008] Furthermore, a spacing adjustment assembly is provided between the multiple suction cup groups. The spacing adjustment assembly includes a spacing connecting plate for connecting adjacent sliding seats and a driving component for driving the sliding seats to move left and right. One end of the spacing connecting plate is fixed to one of the sliding seats, and the other end is provided with a first strip-shaped adjustment groove along the length extension direction of the spacing connecting plate. A limit post is provided on the other sliding seat, and the limit post slides within the first strip-shaped adjustment groove.

[0009] Furthermore, the driving component is a rodless cylinder, with both ends of the rodless cylinder connected to the fixed plate via cylinder head connecting plates. The rodless cylinder is equipped with a sliding piston control slider, which is connected to the rightmost sliding seat via a rodless cylinder fixed seat.

[0010] Furthermore, each suction cup group is configured with 2 suction cups, and a second strip-shaped adjustment groove is also provided on the sliding seat at the position corresponding to the suction cup. The suction cup connecting shaft passes through the second strip-shaped adjustment groove and is fixedly connected to the second strip-shaped adjustment groove by a radial locking nut.

[0011] Furthermore, the clamping rotation assembly includes multiple pairs of active rotating clamping parts and driven rotating clamping parts. The active rotating clamping part includes an active clamping seat and a rotary motor. The active clamping seat is rotatably connected to the first connecting plate via a bearing and is driven by the rotary motor. The driven rotating clamping part includes a driven clamping seat, which is rotatably connected to the second connecting plate via a bearing. Both the first connecting plate and the second connecting plate are disposed on a front-back sliding assembly, and the first connecting plate and the second connecting plate move relative to each other under the action of the front-back sliding assembly.

[0012] Furthermore, the front and rear sliding assembly includes a pair of front and rear guide rails disposed on the frame, the first connecting plate and the second connecting plate being slidably disposed on the front and rear guide rails by means of sliders, and also includes at least a pair of drive cylinders, the bases of the pair of drive cylinders being connected to the frame by means of a fixing frame, and their actuators being connected to the first connecting plate and the second connecting plate respectively.

[0013] Furthermore, the left and right sliding assembly is an electric slide table mounted on the frame, and the adsorption and gripping assembly is mounted on the electric slide table.

[0014] Furthermore, a vertically connected housing is provided between the clamping and rotating assembly and the camera, and an LED light source is also provided inside the housing.

[0015] Beneficial effects:

[0016] 1. This utility model, by installing an adsorption gripping component on the frame, can grip products (pens or other items) conveyed from the transmission line using suction cups. After gripping, the product is moved to a vision positioning station via a left-right sliding component. Then, a clamping and rotating component holds the product gripped by the adsorption gripping component. A camera located below performs vision positioning. Based on the image captured by the camera, the clamping and rotating component clamps and rotates the product to ensure that all gripped products are oriented in the same direction. The product is then gripped again by the adsorption gripping component and moved to the next conveyor line via the left-right sliding component. This achieves fully automated vision positioning operation, facilitating labeling operations at the next station.

[0017] 2. This utility model's adsorption and gripping component uses suction cups for adsorption, and utilizes a vacuum generator to achieve vacuum suction cup adsorption, making gripping easier. Simultaneously, the longitudinal sliding component utilizes a longitudinal guide rail and a lifting cylinder in conjunction. The lifting cylinder drives the lifting base to move up and down, thereby achieving the overall up and down movement of the adsorption and gripping component and enabling precise product positioning.

[0018] 3. The spacing adjustment component set between multiple suction cup groups in this utility model can realize the spacing adjustment of the sliding seats, thereby realizing the spacing adjustment between adjacent suction cup groups. In use, the sliding seats of multiple suction cup groups are slid to the leftmost position. At this time, the multiple sliding seats are in the closest position, and the limiting post is on the innermost side of the first strip groove. At this time, the suction cups adsorb the product from the transmission line. After adsorption, the spacing adjustment component needs to be used to extend to the right by the rodless cylinder to pull open the spacing adjustment component, so that the limiting post is on the outermost side of the first strip groove. The pulled-out sliding seat adapts to the spacing between the clamping rotating components. The sliding seat on one side is driven to slide left and right by the driving component. Because the sliding seats are connected by the spacing connecting plate, after one sliding seat moves left and right, the other sliding seats are pulled left and right by the action of the spacing connecting plate, which can adaptively adjust the spacing between adjacent suction cup groups.

[0019] 4. This utility model achieves the adjustment of the spacing through a rodless cylinder. During the left and right movement of the slider controlled by the piston of the rodless cylinder, the piston drives one of the sliding seats to move, thereby enabling the other sliding seats to move left and right on the connecting shaft, thus achieving adjustment.

[0020] 5. Each suction cup group of this utility model is set with 2 suction cups. The distance between the two suction cups can be adjusted according to the product size. The position of the suction cup connecting shaft is adjusted by the second strip adjustment groove and locked by the radial locking nut. The adjustment is convenient.

[0021] 6. In achieving visual positioning, this utility model relies on a clamping and rotating assembly to complete the product clamping and rotation operations. After the suction cup is in place, the clamping operation is completed by a pair of active and passive rotating clamping parts. During visual positioning, a rotary motor drives the active clamping seat to rotate, thereby rotating the clamped product. Furthermore, to accommodate clamping and rotation operations for different product sizes, the first and second connecting plates are mounted on the front and rear sliding assemblies, allowing them to slide relative to each other. The distance between the first and second connecting plates can be adjusted, thereby achieving adjustment of the clamping distance.

[0022] 7. In order to realize the left and right sliding of the adsorption and gripping component, this utility model sets the left and right sliding component as an electric slide table structure, places the adsorption and gripping component on it, and uses a motor to drive the electric slide rail to slide left and right to realize automatic work station transfer.

[0023] 8. This utility model sets up a housing between the clamping and rotating component and the camera, and sets up an LED light source inside the housing to prevent external light sources from affecting the camera and reduce the impact of environmental factors. Attached Figure Description

[0034] This utility model discloses a visual positioning adjustment device, including a frame 1 and a left-right sliding assembly 2 disposed on the frame 1. At least one set of adsorption and gripping components 3 are slidably disposed on the left-right sliding assembly 2. See [reference needed] Figure 1 In this embodiment, two sets of adsorption and gripping components 3 are provided. A clamping and rotating component 4 is also provided on the frame 1. Below the clamping and rotating component 4, a set of cameras 5 is also provided on the frame 1, facing the product clamped on the clamping and rotating component 4. One set of adsorption and gripping components 3 grips the product on the transmission line 7 and moves towards the clamping and rotating component 4 under the action of the left and right sliding component 2. After the clamping and rotating component 4 clamps the product, the camera 5 is activated (at this time, the adsorption and gripping component 3 can return to the position of the transmission line 7 to continue the next round of gripping). Based on the image captured by the camera 5, the product is rotated by the clamping and rotating component 4 to the same direction. After rotation, the other set of adsorption and gripping components 3 adsorbs the product and moves it to the transmission line of the other workstation. Furthermore, this invention can also use only one set of adsorption and gripping components 3 without affecting the overall structure.

[0035] See Figure 2 and Figure 3 The adsorption and gripping component 3 includes multiple sets of suction cups, each set having at least one suction cup 316. In this embodiment, six sets of suction cups are provided, capable of adsorbing and gripping six products at a time. Each set of suction cups has two suction cups, which together adsorb products on the conveyor line. The suction cup sets are connected to a vacuum generator, which controls the adsorption and release of the suction cups 316.

[0036] Each suction cup group is connected to a sliding base 302 via a suction cup connecting shaft 301. Multiple suction cup groups are connected in series via a pair of connecting shafts 303. Six suction cup groups are arranged side by side. The sliding base 302 of each suction cup group is slidably mounted on the connecting shaft 303 via a linear bearing. In the six suction cup groups, the sliding base 302 of one side of the suction cup group is fixedly connected to a fixed plate 304. The sliding bases 302 of the other suction cup groups are slidably mounted on the connecting shaft 303 via linear bearings and then connected to another fixed plate 304 via one end of the connecting shaft 303. (See [reference]). Figure 1 ,by Figure 1 From a positional perspective, the sliding seat 302 of the leftmost suction cup assembly is fixedly connected to a fixed plate 304, while the other sliding seats 302 on the right are slidably mounted on the connecting shaft 303. The two fixed plates 304 are connected to the longitudinal sliding assembly, which controls the lifting and lowering of the entire suction cup assembly to grip the product downwards.

[0037] In this embodiment, the longitudinal sliding assembly includes a guide rail fixing seat 305, a lifting seat 306, a pair of longitudinal guide rails 307, and a lifting cylinder 308. A fixing plate 304 is fixed to the lifting seat 306, and the pair of longitudinal guide rails 307 are vertically arranged on the guide rail fixing seat 305. The lifting seat 306 is fixedly connected to the sliders arranged on the pair of longitudinal guide rails 307. The actuating end of the lifting cylinder 308 is connected to the lifting seat 306. The guide rail fixing seat 305 is disposed on the left-right sliding assembly 2. In this embodiment, the left-right sliding assembly 2 is implemented by an electric slide table. The guide rail fixing seat 305 is directly fixed to the electric slide table, and the electric slide table is driven by a drive motor, thereby realizing the left-right movement of the adsorption and gripping assembly 3.

[0038] To facilitate adaptation to different product spacings on the transmission line, this embodiment also includes a spacing adjustment component between multiple suction cup groups, see [link to relevant documentation]. Figure 3 The pitch adjustment assembly includes a pitch connecting plate 309 for connecting adjacent sliding seats 302 and a driving component for moving the sliding seats 302. One end of the pitch connecting plate 309 is fixed to one of the sliding seats 302, and the other end is provided with a first strip-shaped adjustment groove 310 along the length extension direction of the pitch connecting plate 309. A limit post 311 is provided on the other sliding seat 302. The limit post 311 can slide within the first strip-shaped adjustment groove 310. In order to reduce friction, a cam follower is selected for the limit post 311.

[0039] The driving component is a rodless cylinder 312. Both ends of the rodless cylinder 312 are connected to the fixed plate 304 via cylinder head connecting plates 313. A sliding piston control slider 314 is provided on the rodless cylinder 312. The piston control slider 314 is connected to one of the sliding seats 302 via a rodless cylinder fixing seat 315. In this embodiment, the rodless cylinder fixing seat 315 is connected to the outermost movable sliding seat 302 among the six sets of suction cups. Figure 3 On the rightmost sliding seat 302. See also Figure 3 When adjusting using the rodless cylinder 312, the piston controls the slider 314 to push the sliding seat 302 from left to right. The sliding seat 302 slides on the connecting shaft 303 until the limiting post 311 is located at the leftmost side of the first strip-shaped adjustment groove 310, maximizing the spacing. When it is necessary to pick up products on the conveyor line, the piston of the rodless cylinder 312 controls the slider 314 to move to the left until the limiting post 311 is located at the rightmost side of the first strip-shaped adjustment groove 310, minimizing the spacing between the sliding seats 302 to match the product spacing on the conveyor line. The length of the first strip-shaped adjustment groove 310 can be adjusted according to actual needs, with the minimum spacing matching the product spacing on the conveyor line and the maximum spacing matching the spacing between the clamping rotating components 4.

[0040] A second strip-shaped adjustment groove 317 is also provided on the sliding base 302 at a position corresponding to the suction cup 316. The suction cup connecting shaft 301 passes through the second strip-shaped adjustment groove 317 and is fixedly connected to the second strip-shaped adjustment groove 317 by a radial locking nut 318. The relative distance between the two suction cups 316 can be adjusted by the relative position of the suction cup connecting shaft 301 in the second strip-shaped adjustment groove 317 to accommodate products of different lengths.

[0041] See Figure 4 The clamping and rotating assembly 4 includes multiple pairs of active and passive rotating clamping parts. In this embodiment, the number of active and passive rotating clamping parts is the same as the number of suction cups, i.e., six pairs are provided. The active rotating clamping part includes an active clamping seat 401 and a rotary motor 402. The active clamping seat 401 is rotatably connected to the first connecting plate 404 via bearings and is driven by the rotary motor 402. The passive rotating clamping part includes a passive clamping seat 403, which is rotatably connected to the second connecting plate 405 via bearings. Both the first and second connecting plates 404 and 405 are mounted on a front-to-back sliding assembly, and move relative to each other under the action of the front-to-back sliding assembly.

[0042] The front and rear sliding assembly includes a pair of front and rear guide rails 406 mounted on the frame 1. The first connecting plate 404 and the second connecting plate 405 are respectively slidably mounted on the front and rear guide rails 406 via sliders. It also includes at least a pair of drive cylinders 407. The bases of the pair of drive cylinders 407 are connected to the frame 1 via a fixing bracket 408, and their actuators are respectively connected to the first connecting plate 404 and the second connecting plate 405.

[0043] In this embodiment, a vertically penetrating housing 6 is also provided between the clamping and rotating assembly 4 and the camera 5, and an LED light source (not shown in the figure) is also provided inside the housing 6.

[0044] Working principle:

[0045] 1. When the product is transported to the current gripping station via the conveyor line, in this embodiment, the product is set as an eyebrow pencil, which is vertically positioned on the conveyor line 7. (See [reference]). Figure 5 .

[0046] 2. Move to below the adsorption and gripping component 3, control the lifting cylinder 308 to move, drive the lifting seat 306 to move downward on the longitudinal guide rail 307, move to the eyebrow pencil position close to the transmission line, at this time the rodless cylinder 312 controls the six sliding seats 302 to be in the minimum spacing state, to match the product spacing on the transmission line 7.

[0047] 3. Activate the vacuum generator. Suction cup 316 begins operation, adsorbing the eyebrow pencil on the transmission line. Then, lifting cylinder 308 operates, lifting the suction cup assembly upwards and activating the left-right sliding component 2. This causes the guide rail fixing seat 305, i.e., the entire suction cup assembly, to move closer to the clamping rotating component 4. During this process, rodless cylinder 312 operates, controlling the six sliding seats 302 to be at their maximum spacing, adapting to the spacing required by the clamping rotating component 4.

[0048] 4. Move to the position directly above the clamping and rotating assembly 4, start the lifting cylinder 308, and control the adsorption and gripping assembly 3 to move downward until the product is located in the clamping position of the clamping and rotating assembly 4.

[0049] 5. Start the drive cylinder 407. The drive cylinder 407 moves the first connecting plate 404 and the second connecting plate 405 closer together, causing the active clamping seat 401 and the driven clamping seat 403 on them to move closer together, clamping the eyebrow pencil adsorbed on the suction cup 316. At this time, control the vacuum generator to stop working, and the suction cup completes the adsorption work. At the same time, control the lifting cylinder 308 to move the suction cup 316 upward as a whole. At this time, the clamping rotation component 4 works, and the adsorption gripping component 3 can return to the loading position on the left and right sliding component 2.

[0050] 6. Turn on camera 5 and LED light source to start visual positioning. Based on the image captured by camera 5, start rotating motor 402. In this embodiment, 6 sets of rotating motor 402 are set. The rotation time of rotating motor 402 is started according to the angle of the eyebrow pencil until all eyebrow pencils are rotated to the position of the marker facing the camera 5.

[0051] 7. When camera 5 stops working, another suction gripping component 3 set on the left and right sliding component 2 moves to above the clamping rotation component 4 under the action of the left and right sliding component 2. The lifting cylinder 308 is activated, which drives the suction cup 316 to move downward to above the space between the active clamping seat 401 and the driven clamping seat 403, close to the eyebrow pencil. The vacuum generator is activated, which drives the suction cup 316 to adsorb the eyebrow pencil and controls the lifting cylinder 308 to move upward. At the same time, the left and right sliding component 2 is activated, which drives the guide rail fixing seat 305 on it, i.e. the entire suction cup group, to move to the other side of the clamping rotation component 4 and transport the eyebrow pencil to the transmission line on the other side (not shown in the figure). (At this time, the rodless cylinder 312 controls the six sets of sliding seats 302 to be in the minimum spacing state to adapt to the product spacing required on the transmission line), thus completing one round of visual positioning.

[0052] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
