Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a clamping and rotating mechanism. Background Art

[0002] During the loading process for electronic product production, incoming materials such as Wi-Fi cards (wireless network cards), SSDs (solid-state drives), DDRs (double-bit synchronous dynamic random access memory), and other boards are often inserted vertically or stored horizontally.

[0029] See Figures 1 to 6This embodiment provides a gripping and rotating mechanism, comprising a bracket 1, a gripping unit 3, and a rotating drive unit 2. Both the gripping unit 3 and the rotating drive unit 2 are disposed on the bracket 1. The gripping unit 3 and the rotating drive unit 2 are disposed on either side of the bracket 1 along a first direction. The bracket 1 can be mounted on a device capable of driving its movement. The gripping unit 3 comprises a first driving member 31 and two rotating arms 32. The two rotating arms 32 are respectively disposed at the driving ends of the first driving member 31 so as to be able to pitch upward and downward. The driving ends of the first driving member 31 move toward and away from each other in the first direction, thereby driving the two rotating arms 32 to move toward and away from each other in the first direction. When the two rotating arms 32 move toward each other in the first direction, they can grip material; when they move away from each other, they can release material. The rotating drive unit 2 is transmission-connected to the two rotating arms 32, respectively, for driving the two rotating arms 32 to pitch upward and downward. The rotating arms 32 are disposed at the driving ends of the first driving member 31 so as to be able to pitch upward and downward. Driven by the rotating drive unit 2, the rotating arms 32 can pitch upward and downward to change the shape of the gripped material.

[0030] In this embodiment, the two rotating arms 32 can be moved closer and further apart to achieve product gripping and release. The rotation drive unit 2 can drive the two rotating arms 32 to pitch, and simply by pitching and rotating the two rotating arms 32, product direction can be reversed. This results in a simple, low-cost, compact structure that takes up little space. After gripping a product, the rotating arms 32 can be pitched and rotated during the product transfer process to adjust the product's angle, achieving greater efficiency.

[0031] In one embodiment, Figure 1 、 Figure 4 and Figure 5 As shown, a rotating shaft is respectively provided on opposite sides of the two rotating arms 32 , and the two rotating shafts are arranged opposite to each other. The rotating arms 32 are arranged on the driving end of the first driving member 31 so as to be pitchable along the axis of the rotating shaft.

[0032] In one embodiment, Figures 1 to 4 As shown, the rotation drive unit 2 includes a second drive member 21 and an intermediate connection member 22. The intermediate connection member 22 is arranged on the driving end of the second drive member 21. The second drive member 21 is used to drive the intermediate connection member 22 to move in the vertical direction. The intermediate connection member 22 is respectively connected to the two rotating arms 32 to drive the two rotating arms 32 to pitch. The driving end of the second drive member 21 can move in the vertical direction to drive the intermediate connection member 22 arranged on the driving end of the second drive member 21 to move in the vertical direction, thereby driving the two rotating arms 32 to pitch and rotate to adjust the posture of the product. The above structure only requires the driving end of the second drive member 21 to move in the vertical direction to drive the two rotating arms 32 to pitch. The structure occupies a small space and the space occupied during movement is also small, so that this embodiment can have a wider range of application scenarios.

[0033] In one embodiment, Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, guide shafts 321 are provided on opposite sides of the two pivoting arms 32. Guide slots 221a extending in the second direction are provided on either side of the intermediate connector 22. The first direction is perpendicular to the second direction. The two guide shafts 321 are movably disposed within the two guide slots 221a, respectively, along the second direction, enabling the intermediate connector 22 to drive the two pivoting arms 32 in pitch. The first and second directions are perpendicular horizontal directions and are both perpendicular to the vertical direction. The guide shafts 321 are disposed on opposite sides of the two pivoting arms 32 to prevent interference when the pivoting arms 32 approach each other. The guide shafts 321 can rotate along their own axes within the guide slots 221a and can also move in the second direction. When pressed downward by the intermediate connector 22, the guide shafts 321 can drive the pivoting arms 32 in pitch, thereby causing the product being gripped by the pivoting arms 32 to change its pitch. This structure is simple, cost-effective, and requires minimal space.

[0034] In one embodiment, Figure 3 As shown, the intermediate connector 22 has two pressing arms 221 extending along the second direction, and two guide grooves 221a are respectively provided on the two pressing arms 221. The intermediate connector 22 includes an intermediate connector body 222 and two pressing arms 221, and the two pressing arms 221 are provided on the intermediate connector body 222 along the second direction. The two pressing arms 221 are provided on the side of the intermediate connector body 222 facing the clamping unit 3, and the two pressing arms 221 are respectively provided on both ends of the intermediate connector body 222 along the first direction. The above structure further simplifies the structure of the intermediate connector 22, reduces the space it occupies, and can also avoid interference with the clamping unit 3 during movement.

[0035] In one embodiment, the guide groove 221 a can penetrate the pressing arm 221 along the first direction, so as to facilitate the movement of the guide shaft 321 in the guide groove 221 a.

[0036] In one embodiment, Figure 5 As shown, the second driving member 21 is a double-axis cylinder. The double-axis cylinder has double piston rods, has a large output force, can save installation space, has good guiding performance, and can withstand lateral loads.

[0037] In one embodiment, Figures 1 to 4As shown, the rotation drive unit 2 also includes an angle adjustment screw 4 for adjusting the rotation angle of the rotation arm 32. The first end of the angle adjustment screw 4 passes through the intermediate connector 22 and is mounted on the bracket 1. A nut is fitted on the first end of the angle adjustment screw 4 for tightening. The second end is located on the side of the intermediate connector 22 facing away from the second drive member 21. The first end of the angle adjustment screw 4 is threaded, facing upward. The threaded end passes through the intermediate connector 22 and is tightened to the bracket 1 via a nut. The second end of the angle adjustment screw 4 is headed, facing downward and located at the bottom of the intermediate connector 22. When the intermediate connector 22 moves downward and contacts the head of the angle adjustment screw 4, the top surface of the head of the angle adjustment screw 4 can abut against the bottom of the intermediate connector 22, preventing further downward movement of the intermediate connector 22. By turning the nut on the angle adjustment screw 4, the height of the head (second end) of the angle adjustment screw 4 is adjusted, limiting the maximum downward movement of the intermediate connector 22, thereby adjusting the maximum rotation angle of the product. The maximum angle at which the product can rotate can be changed by the angle adjustment screw 4 , so that this embodiment can be applied to different products.

[0038] In one embodiment, the first driving member 31 is a finger cylinder. A finger cylinder, also known as a pneumatic finger, or pneumatic gripper, is an actuator that uses compressed air as a power source to grip or grasp a workpiece. The finger cylinder features a compact form factor, small size, low cost, simple maintenance, and light weight, making the overall structure of this embodiment more compact and space-saving.

[0039] In one embodiment, Figures 3 to 5 As shown, the gripping unit 3 further includes fixed arms 33, which are respectively disposed on the two driving ends of the two first driving members 31. The two rotating arms 32 are respectively disposed on the two driving ends of the first driving members 31 via the two fixed arms 33 so as to be tiltable. The fixed arms 33 are disposed in a vertical direction, and the driving end of the first driving member 31 is also disposed in a vertical direction. The fixed arms 33 are externally mounted on the driving end of the first driving member 31, and the two rotating arms 32 are respectively disposed on opposite sides of the fixed arms 33 so as to be tiltable. The rotating arms 32 are disposed on the driving end of the first driving member 31 via the fixed arms 33, which can further stabilize the connection of the rotating arms 32.

[0040] In one embodiment, Figure 6 As shown, recessed portions 331 are respectively provided on opposite sides of the two fixed arms 33, and the top ends of the two rotating arms 32 are respectively disposed in the two recessed portions 331. The recessed portions 331 extend upward from the bottoms of the fixed arms 33. The height of the recessed portions 331 is greater than or equal to the height of the rotating arms 32 mounted on the fixed arms 33, so that the rotating arms 32 can be mounted on the recessed portions 331, thereby reducing the overall volume and space occupied by this embodiment.

[0041] In one embodiment, Figure 6 As shown, the recessed portion 331 is a step, which is convenient for processing and can make the installation of the rotating arm 32 more stable.

[0042] During operation, when the gripping and flipping mechanism moves above a product, the two driving ends of the first driving member 31 respectively drive the two fixed arms 33 toward each other, thereby driving the two rotating arms 32 toward each other to pick up the product. After picking up the product, the gripping and flipping mechanism moves toward the discharge area. During this movement, the driving end of the second driving member 31 drives the intermediate connecting member 22 downward. As the intermediate connecting member 22 moves downward, it drives the two guide shafts 321 to rotate clockwise or counterclockwise (pitch) along their own axes, and the guide shafts 321 move within the guide slots 221a. As the guide shafts 321 rotate, the rotating arms 32 also rotate synchronously to adjust the posture of the gripped product (to the angle required for the product in the discharge area). After the gripping and flipping mechanism reaches the discharge area, the two driving ends of the first driving member 31 respectively drive the two fixed arms 33 away from each other to place the product, completing a single pick-up and discharge operation.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
