Description

Technical Field

[0001] This utility model relates to the field of product parts feeding technology, and more specifically, to a feeding and positioning device. Background Technology

[0002] Currently, some products require the embedding of metal contacts in their die-cast housings for convenient charging connections. These die-cast housings are typically made of cast aluminum, and metal sheets need to be pre-embedded in the casting mold during the die-casting process. Multiple metal sheets need to be installed at once. If installed manually, these sheets must be placed into the casting mold sequentially. Due to the high temperature of the casting mold, the first sheets placed will warp and deform under the high temperature, significantly increasing the defect rate and reducing production efficiency. Furthermore, the die-casting process involves high operating temperatures and a harsh environment, making manual installation of the metal sheets highly dangerous.

[0003] Therefore, automatic feeding of metal sheets is required. However, before multiple metal sheets are embedded at the same time, the arrangement of the metal sheets is often disordered and cannot be matched with the casting mold and put in. Manual adjustment is labor-intensive and reduces production efficiency. Utility Model Content

[0004] This invention provides a feeding and positioning device to solve the problem of high time and labor costs caused by manually adjusting the position of metal sheets or other workpieces in the prior art.

[0005] To address the aforementioned problems, this utility model provides a feeding and positioning device, comprising: a vibrating part having a vibration zone for supporting multiple workpieces, the vibration zone being vibratingly configured to screen multiple workpieces; a positioning fixture including a positioning base and multiple positioning structures distributed on the positioning base; and a positioning robot including a robotic arm and an adsorption clamp, the adsorption clamp being mounted at the end of the robotic arm, the robotic arm driving the adsorption clamp to move, the adsorption clamp being used to adsorb workpieces within the vibration zone and placing one workpiece on each positioning structure.

[0006] Furthermore, the positioning structure includes a support block and a positioning post disposed on the support block. The support block is used to support the workpiece, and the positioning post is used to limit the engagement with the slot or hole of the workpiece.

[0007] Furthermore, there are two positioning posts, and the positioning structure also includes multiple support posts distributed between the two positioning posts, which are used to support the workpiece.

[0008] Furthermore, the feeding and positioning device also includes a support platform, on which the vibration unit, positioning fixture, and positioning robot are all installed; the positioning base has multiple positioning holes, and wear-resistant sleeves are installed inside the positioning holes; multiple positioning pins are installed on the support platform, and each positioning pin is inserted into a positioning hole.

[0009] Furthermore, the adsorption fixture includes an adsorption rod with a negative pressure channel inside, and a limiting groove at the end of the adsorption rod, the shape of which matches the shape of the protrusion on the workpiece.

[0010] Furthermore, the adsorption fixture also includes a first mounting base, a second mounting base, and a negative pressure connector. The first mounting base is mounted on the positioning robot, the second mounting base is mounted on the first mounting base, the adsorption rod is mounted on the second mounting base, the negative pressure channel is connected to the cavity in the second mounting base, and the negative pressure connector is mounted on the second mounting base, with the cavity in the negative pressure connector and the cavity in the second mounting base connected.

[0011] Furthermore, the robotic arm includes a robot base, a horizontal swing arm, a rotating part, and a lifting part. The two ends of the horizontal swing arm are connected to the robot base and the rotating part, respectively. The lifting part is installed inside the rotating part and can be raised and lowered. The rotating part can drive the lifting part to rise and fall. The suction gripper is installed at the lower end of the lifting part.

[0012] Furthermore, the feeding and positioning device also includes a storage box, which stores multiple workpieces and transports them to the vibration zone.

[0014] Furthermore, the loading and positioning device also includes a vision recognition unit and a control unit. The vision recognition unit is used to identify the workpiece in the vibration zone. The vision recognition unit and the positioning robot are both electrically connected to the control unit. The control unit controls the positioning robot to pick up the workpiece based on the recognition result of the vision recognition unit.

[0015] In this solution, the vibration zone of the vibrating part disperses the workpieces, allowing the positioning robot to pick up individual workpieces. The suction gripper in the positioning robot picks up the workpieces from the vibration zone, and the robotic arm transfers the workpieces to different positions, placing one workpiece on each positioning structure. Multiple positioning structures allow multiple workpieces to be placed on the positioning fixture simultaneously, defining the relative positions between them.

[0027] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0028] like Figures 1 to 4As shown, an embodiment of this utility model provides a feeding and positioning device, including: a vibration unit 10, the vibration unit 10 having a vibration zone 11 for carrying multiple workpieces, the vibration zone 11 being vibratoryly arranged to screen multiple workpieces; a positioning fixture 20, the positioning fixture 20 including a positioning base 21 and multiple positioning structures 22, the multiple positioning structures 22 being distributed on the positioning base 21; and a positioning robot 30, the positioning robot 30 including a robotic arm 31 and an adsorption clamp 32, the adsorption clamp 32 being installed at the end of the robotic arm 31, the robotic arm 31 driving the adsorption clamp 32 to move, the adsorption clamp 32 being used to adsorb workpieces in the vibration zone 11 and placing one workpiece on each positioning structure 22 respectively.

[0029] In this design, the vibration zone 11 of the vibration unit 10 disperses the workpieces, allowing the positioning robot 30 to pick up individual workpieces. The suction gripper 32 in the positioning robot 30 picks up the workpieces in the vibration zone 11, and the robotic arm 31 transfers the workpiece position, placing one workpiece on each positioning structure 22. Multiple positioning structures 22 allow multiple workpieces to be placed on the positioning fixture 20 simultaneously, and define the relative positions between the multiple workpieces. Through automated positioning operations, the arrangement direction and position of the workpieces are adjusted, improving the accuracy of matching the workpieces with the casting mold in subsequent processes. This facilitates the simultaneous placement of multiple workpieces into the casting mold, improving production efficiency and saving labor costs.

[0030] like Figure 4 As shown, the positioning structure 22 includes a support block 221 and a positioning post 222 disposed on the support block 221. The support block 221 is used to support the workpiece, and the positioning post 222 is used to limit the engagement with the slot or hole of the workpiece. The workpiece is transferred to the support block 221 of the positioning structure 22 by the robotic arm 31. The positioning post 222 engages with the slot or hole of the workpiece to limit the engagement, so as to adjust multiple workpieces to the same orientation, improve the accuracy of matching the workpiece with the casting mold in subsequent processes, and facilitate the simultaneous placement of multiple workpieces into the casting mold.

[0031] In this embodiment, there are two positioning posts 222, and the positioning structure 22 also includes multiple support posts 223. The multiple support posts 223 are distributed between the two positioning posts 222 and are used to support the workpiece. The multiple support posts 223 distributed between the two positioning posts 222 can support the workpiece placed between the positioning posts 222 and prevent the workpiece from becoming unstable and tilting to the left or right.

[0032] like Figure 1 , Figure 3As shown, the loading and positioning device also includes a support platform 40, on which the vibration unit 10, positioning fixture 20, and positioning robot 30 are all mounted. The positioning base 21 has multiple positioning holes, each containing a wear-resistant sleeve 211. The support platform 40 has multiple positioning pins, each inserted into a positioning hole. The support platform 40 provides an installation platform for the vibration unit 10, positioning fixture 20, and positioning robot 30. The multiple positioning holes on the positioning base 21 correspond to the multiple positioning pins on the support platform 40 and are engaged for fixation, ensuring that the relative position of the positioning base 21 on the support platform 40 remains unchanged, facilitating the identification and positioning of workpieces placed on the positioning base 21.

[0033] like Figure 2 As shown, the adsorption fixture 32 includes an adsorption rod 321 with a negative pressure channel inside. The end of the adsorption rod 321 has a limiting groove 3211, the shape of which matches the shape of a protrusion on the workpiece. The negative pressure channel inside the adsorption rod 321 ensures stable adsorption and transfer of the workpiece while preventing scratches or other damage. The matching shape of the limiting groove 3211 with the protrusion on the workpiece further improves the stability and accuracy of the adsorption rod 321 in adsorbing the workpiece.

[0034] In this embodiment, the adsorption clamp 32 further includes a first mounting base 322, a second mounting base 323, and a negative pressure connector 324. The first mounting base 322 is mounted on the positioning robot 30, the second mounting base 323 is mounted on the first mounting base 322, the adsorption rod 321 is mounted on the second mounting base 323, the negative pressure channel is connected to the cavity in the second mounting base 323, and the negative pressure connector 324 is mounted on the second mounting base 323, with the cavity in the negative pressure connector 324 connected to the cavity in the second mounting base 323. This structural design makes the installation and adjustment of the adsorption clamp 32 more flexible, while the negative pressure connector 324 ensures the stability of the negative pressure system, improving the stability and efficiency of workpiece gripping.

[0035] like Figure 1 As shown, the robotic arm 31 includes a robot base 311, a horizontal swing arm 312, a rotating part 313, and a lifting part. The two ends of the horizontal swing arm 312 are connected to the robot base 311 and the rotating part 313, respectively. The lifting part is vertically mounted within the rotating part 313, and the rotating part 313 drives the lifting part to move up and down. A suction clamp 32 is mounted at the lower end of the lifting part. The horizontal swing arm 312 can transfer the workpiece from the vibrating part 10 to the positioning fixture 20. The rotating part 313 can adjust the angle of the workpiece, allowing the positioning pin 222 to engage with the slot or hole of the workpiece. The lifting part can pick up and place the workpiece. The coordinated operation of the horizontal swing arm 312, the rotating part 313, and the lifting part enables the transfer and orientation adjustment of the workpiece.

[0036] In this embodiment, the feeding and positioning device also includes a storage box 50, which stores multiple workpieces and transports them to the vibration zone 11. The storage box 50 is used to store workpieces, enabling continuous supply of workpieces, reducing manual intervention, and improving the level of production automation.

[0037] In this embodiment, the storage box 50 is installed higher than the vibration zone 11; the feeding and positioning device also includes a conveying chute, one end of which is connected to the outlet of the storage box 50, and the other end of which extends to the vibration zone 11; the storage box 50 is vibratingly configured to output the workpiece through vibration. The configuration of the conveying chute, combined with the vibration output of the storage box 50, achieves efficient and continuous conveying of the workpiece, reduces blockage and jamming of the workpiece during the conveying process, and improves the operating efficiency and stability of the feeding and positioning device.

[0038] In this embodiment, the loading and positioning device further includes a vision recognition unit 70 and a control unit. The vision recognition unit 70 is used to identify workpieces on the vibration zone 11. The vision recognition unit 70 and the positioning robot 30 are both electrically connected to the control unit. The control unit controls the positioning robot 30 to pick up the workpiece based on the recognition result of the vision recognition unit 70. The vision recognition unit 70 can identify workpieces with their protruding shape facing upwards and not overlapping with other workpieces. It can also identify the angle of the workpiece and compare it with the position of the positioning post on the positioning structure. After the suction clamp picks up the workpiece, it rotates the corresponding angle according to the recognition result, so that the workpiece is placed in conjunction with the positioning post on the positioning structure. This improves the automation level and positioning accuracy of the device, and increases the loading and positioning efficiency.
