Description

Technical Field

[0001] This utility model belongs to the field of automatic feeding technology, and in particular relates to a camera positioning and feeding device. Background Technology

[0002] Flexible vibratory feeders are automated feeding devices suitable for the arrangement and feeding of small and medium-sized parts in automated production. They solve the problem of feeding irregularly shaped parts, effectively avoiding product damage and material jamming. A flexible vibratory feeder consists of a base plate, voice coil motor modules, a backlight panel (light source), a feeding tray, and a controller. Powered by voice coil motors, the controller adjusts the vibration amplitude and frequency of each motor, allowing parts to move in any direction on the tray surface. Vibration and flipping of the parts achieve separation and directional movement. Combined with machine vision recognition technology, the shape and position information of the parts is obtained, and the coordinate data is sent to the robot's moving mechanism. Based on the data sent by the vision system, the robot identifies the part's position and picking direction, and picks up the parts from the tray surface for array arrangement or assembly. Therefore, it is widely used in automated production lines to achieve automated feeding.

[0003] Chinese invention patent application CN119099936A discloses an automatic heat sink loading and packaging device, including a lower frame and an upper frame mounted on top of the lower frame. It also includes a flexible vibratory feeder, a peeling mechanism, and a tape-sealing unit. The flexible vibratory feeder, peeling mechanism, and tape-sealing unit are all mounted on the upper part of the lower frame. The flexible vibratory feeder can flip the heat sink, the peeling mechanism can peel the Mylar sheet from the tape, and the tape-sealing unit can tape-seal the heat sink. A robotic arm is mounted inside the top of the upper frame. The robotic arm can first attach the Mylar sheet to the heat sink and then transfer the heat sink to the tape-sealing unit. However, the technical solution in this patent relies on manual addition of materials to the flexible vibratory feeder, thus requiring manual monitoring of the presence of materials in the vibratory feeder and the addition of materials. This increases the workload of the workers.

[0004] Chinese utility model patent document CN221138804U discloses an automatic feeding device for bagged wire harnesses, comprising a hopper for storing bagged wire harnesses, a discharge port located on one side of the hopper, a flexible vibrating plate located on one side of the hopper and below the discharge port, a feeding mechanism located at the bottom of the hopper for placing a portion of the bagged wire harnesses from the hopper onto the flexible vibrating plate each time, and a vision positioning mechanism located above the flexible vibrating plate for reading the position of the bagged wire harnesses on the flexible vibrating plate. The feeding mechanism can place a portion of the bagged wire harnesses from the hopper onto the flexible vibrating plate each time. The vibration of the flexible vibrating plate disperses the bagged wire harnesses, and the vision positioning mechanism reads the position of the bagged wire harnesses on the flexible vibrating plate, facilitating robotic arm grasping and improving the grasping success rate. The feeding mechanism includes a feeding rack vertically installed at the bottom of the hopper, a lifting cylinder vertically installed on the feeding rack, a top column vertically installed at the driving end of the lifting cylinder with its upper end inside the hopper for lifting the bagged wire harness inside the hopper to the discharge port, a translation cylinder horizontally installed on one side of the hopper, and a pusher rod installed at the driving end of the translation cylinder for pushing the bagged wire harness on the top column toward the discharge port. During operation: first, the lifting cylinder drives the top column to lift the bagged wire harness inside the hopper to the discharge port, and then the translation cylinder drives the pusher rod to push the bagged wire harness on the top column toward the discharge port, where it falls onto the surface of the flexible vibrating plate.

[0005] The aforementioned patent document achieves automatic feeding through a feeding mechanism; however, this causes materials to accumulate at the discharge port, making it difficult to identify and pick up the materials. Utility Model Content

[0007] To achieve the above objectives, this utility model provides a camera positioning and feeding device, comprising a flexible vibratory feeder, a hopper, a tray, a linear module, and a slide. The hopper includes a lifting mechanism and a rack mounted on the lifting mechanism. The rack has multiple layers of trays, each tray supporting a tray. One end of the tray has a connecting plate with a limiting hole. Ears extend from both sides of the bottom of the tray. The flexible vibratory feeder is located on one side of the hopper. A carrier plate is connected to the top of the vibratory feeder. Downward driving components are located on both sides of the carrier plate, and each downward driving component has a pressure plate extending to the top of the carrier plate. The linear module is located on one side of the flexible vibratory feeder. One end of the slide is connected to the linear module, and the other end extends to the top of the carrier plate. An extension portion extends towards one side of the hopper. A limiting post is located on the bottom of the extension portion. The limiting post engages with the limiting hole, and the diameter or minimum width of the limiting hole is greater than the diameter of the limiting post.

[0008] Furthermore, pulley sets are provided on both sides of the carrier plate, and the pulley sets form guide grooves for guiding the material tray to move to the top side of the carrier plate; a limiting member is also provided at one end of the carrier plate for limiting the material tray.

[0009] Furthermore, the flexible vibratory feeder is provided with a vertical plate on the side near the hopper, the vertical plate is provided with an air-avoiding window, and an induction switch is provided above the air-avoiding window for detecting the slide plate and the feed tray.

[0010] Furthermore, the flexible vibratory feeder is provided with an ion air bar on the side away from the hopper, and the ion air bar is used to blow ion air onto the feed tray on the top side of the carrier plate.

[0011] Furthermore, the lifting mechanism includes a mounting plate, a lifting frame, and an electric screw assembly; the mounting plate is vertically disposed on the bottom side of the flexible vibratory feeder, and a guide rail is provided on the outer side of the mounting plate, extending to the top of the mounting plate; the lifting frame is connected to the guide rail, and the material rack is disposed on the lifting frame; the electric screw assembly is disposed on the mounting plate and connected to the lifting frame, for pushing the lifting frame to lift.

[0012] Furthermore, the upper end of the mounting plate is provided with side plates on both sides, and the side plate is provided with an elastic baffle on the side near the material rack.

[0016] The camera positioning and feeding device provided in this embodiment of the present invention has at least the following technical effects:

[0017] This camera-positioning and feeding device lays the material flat in a tray, placing one tray containing material on each layer of the pallet. When it is necessary to remove the material from the tray for assembly with other parts, a linear module drives the extension of the slide to extend into the hopper, and a lifting mechanism drives the material rack to rise, causing the tray to rise and the limiting hole to fit onto the limiting post, with the bottom of the tray flush with the carrier plate. The linear module drives the slide to move, thereby pulling the tray out of the material rack and supporting it on the carrier plate.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of the camera positioning and feeding device of this utility model, please refer to... Figures 1 to 4The camera positioning and feeding device of this embodiment is used in automated equipment to achieve automatic feeding, replace manual labor, and improve efficiency. Specifically, the camera positioning and feeding device of this embodiment includes a flexible vibratory feeder 100, a hopper 200, a tray 300, a linear module 400, and a slide plate 500. The hopper 200 includes a lifting mechanism 210 and a rack 220 mounted on the lifting mechanism 210. The rack 220 has multiple layers of trays 230, each tray 230 supporting a tray 300. One end of the tray 300 is also provided with a connecting plate 310, which has a limiting hole 311. Ears 320 extend from both sides of the bottom end of the tray 300. The flexible vibratory feeder 100 is located on one side of the hopper 200. A carrier plate 110 is connected to the top side of the flexible vibratory feeder 100. A pressing drive component 120 is provided on both sides of the carrier plate 110. The pressing drive component 120 can be a cylinder. The downward drive component 120 has a pressure plate 130 extending to the top side of the carrier plate 110. A linear module 400 is located on one side of the flexible vibratory feeder 100. Specifically, the linear module 400 can be a synchronous belt linear module. One end of the slide plate 500 is connected to the linear module 400, and the other end extends to the top side of the carrier plate 110, with an extension 510 extending towards one side of the hopper 200. A limiting post 520 is provided on the bottom side of the extension 510. The limiting post 520 is used to mate with a limiting hole 311, the diameter or minimum width of which is greater than the diameter of the limiting post 520. Specifically, the limiting hole 311 can be a round hole or an oblong hole.

[0028] The camera positioning and feeding device of this embodiment can lay the material flat in the tray 300, and place a tray 300 containing the material on each layer of the pallet 230. When it is necessary to remove the material from the tray 300 to assemble with other parts, the linear module 400 drives the extension of the slide plate 500 to extend into the hopper 200, and the lifting mechanism 210 drives the material rack 220 to rise, so that the tray 300 rises and the limiting hole 311 is fitted onto the limiting post 520, and the bottom of the tray 300 is flush with the carrier plate 110; the linear module 400 drives the slide plate 500 to move, thereby pulling the tray 300 out of the material rack 220 and supporting it on the carrier plate 110. The pressing drive members 120 on both sides of the carrier plate 110 drive the pressure plate 130 to press down on the ears 320 on both sides of the tray 300, thus fixing the tray 300 on the carrier plate 110. The flexible vibrating plate 100 intermittently drives the material tray 300 to vibrate until all the material in the tray 300 is picked up. The empty tray 300 is then pushed back into the hopper 200, and the next tray 300 is pulled out, achieving automatic feeding, replacing manual labor, and improving efficiency. Furthermore, since the material is initially laid flat in the tray, the problem of material accumulation is avoided, making it easier to pick up the material.

[0029] Furthermore, refer to Figure 1The bottom side of the material tray 300 has several bottom holes 301. In this embodiment, the bottom holes 301 can increase the force on the material, making it easier for the material to flip during vibration, and also preventing the material from displacing too much during vibration, causing it to concentrate in the middle position. This also makes it easier to spread the material evenly.

[0030] Furthermore, refer to Figure 1 Both sides of the carrier plate 110 are provided with pulley sets 140, which form guide grooves for guiding the material tray 300 to move to the top side of the carrier plate 110. One end of the carrier plate 110 is also provided with a limiting member 150 for limiting the material tray 300. Specifically, in this embodiment, when the linear module 400 pulls the material tray 300 onto the carrier plate 110, the two sets of pulley sets 140 guide the material tray 300, so that the material tray 300 can be located in the middle position of the carrier plate 110. This facilitates the clamping plate 130 to hold the ear portion 320 of the material tray 300.

[0031] Furthermore, refer to Figure 1 and Figure 2 The flexible vibratory feeder 100 is also provided with a vertical plate 600 on the side near the hopper 200. The vertical plate 600 has a clearance window 601, which is used to prevent the material tray 300 from being transferred from the pallet 230 to the carrier plate 110. A sensor switch 610 is provided above the clearance window 601 to detect the pallet 500 and the material tray 300. Specifically, in this embodiment, when the sensor switch 610 detects the pallet 500, the lifting mechanism 210 drives the material rack 220 to rise, so that the limiting hole 311 can be fitted onto the limiting post 520. When the sensor switch 610 detects that the material tray 300 is located at the clearance window 601, the lifting mechanism 210 will stop working.

[0032] Furthermore, refer to Figure 1 and Figure 2 The flexible vibratory feeder 100 is also equipped with an ion air bar 700 on the side away from the hopper 200. The ion air bar 700 is used to blow ion air onto the feed tray 300 on the top side of the carrier plate 110. This avoids the problem of static electricity generated by the mutual friction of materials vibrating in the feed tray 300, which would cause two or more materials to be picked up during material pickup.

[0033] Furthermore, refer to Figures 1 to 3 The lifting mechanism 210 includes a mounting plate 211, a lifting frame 212, and an electric screw assembly 213. The mounting plate 211 is vertically mounted on the bottom side of the flexible vibratory feeder 100. A guide rail 214 is provided on the outer side of the mounting plate 211, extending to the top of the mounting plate 211. The lifting frame 212 is connected to the guide rail 214, and the material rack 220 is mounted on the lifting frame 212. The electric screw assembly 213 is mounted on the mounting plate 211 and connected to the lifting frame 212, used to push the lifting frame 212 up and down.

[0034] Furthermore, refer to Figure 3 The mounting plate 211 has side plates 215 on both sides of its upper end. An elastic baffle 216 is also provided on the side of the side plate 215 near the material rack 220. The lower end of the elastic baffle 216 extends to the top side of the lifting frame 212 when it reaches its lowest position, and the upper end of the elastic baffle 216 extends to one side of the bottom end of the flexible vibrating plate 100. In this embodiment, the elastic baffle 216 limits the material tray 300 on the tray 230, preventing the material tray 300 from partially slipping out of the material rack 220 and interfering with the lifting process. Furthermore, the elastic baffle 216 elastically presses the material tray 300 within the material rack 220, preventing the material tray 300 from shaking when the lifting mechanism 210 drives it to lift or lower.

[0035] Furthermore, the upper and lower ends of the elastic baffle 216 are provided with inwardly bent guide portions. This facilitates the guiding function of the material tray 300 when it is raised and lowered and comes into contact with or detaches from the elastic baffle 216.

[0036] Furthermore, refer to Figure 1 and Figure 3 A mounting bracket 800 is also provided on one side of the material rack 220. A photoelectric switch 810 is located at the upper end of the mounting bracket 800. The photoelectric switch 810 is used to detect whether the tray 230, which is flush with the height of the carrier plate 110, supports a material tray 300. Specifically, when it is necessary to remove the material tray 300 from the tray 230, the photoelectric switch 810 detects whether there is a material tray 300 on the tray 230. If there is no material tray 300, the lifting mechanism 210 drives the material rack 220 to rise and fall, causing the tray 230 with the material tray 300 to move to one side of the carrier plate 110. When it is necessary to retrieve an empty material tray 300, the photoelectric switch 810 detects whether there is a material tray 300 on the tray 230, avoiding interference problems when retrieving an empty material tray 300.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
