Technical Field

[0001] The utility model relates to the field of mobile phone production equipment, in particular to automatic material grabbing equipment for a mobile phone frame. Background Art

[0002] The metal frame of a mobile phone is the outer shell of the mobile phone. Its main function is to protect the internal components of the mobile phone. It also serves an aesthetic purpose. During the automated production of the mobile phone frame, the mobile phone frame needs to be transferred between each processing station using automated material grabbing equipment.

[0003] After the mobile phone frame is processed, waste chips will remain on its side. When the gripping mechanism directly grabs the material, the clamping claws will come into contact with the waste chips, causing damage and scratches to the mobile phone frame and affecting the gripping accuracy. Utility Model Content

[0004] In view of the above problems, the utility model provides an automatic material grabbing device for mobile phone frames. Two groups of rotatable rotating rods are symmetrically arranged on the mounting base. When clamping, the ends of the rotating rods contact the mobile phone frame and move on the mobile phone frame, thereby scraping off the waste debris. As the rotating rods rotate, the interference rods interfere with the scraping area at the ends of the rotating rods, thereby achieving the grabbing of the mobile phone frame, solving the technical problem in the prior art that waste debris affects the grabbing accuracy and the quality of the mobile phone frame.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic material grabbing device for a mobile phone frame, comprising:

[0007] A transplanting mechanism, the transplanting mechanism comprising a frame, a transverse moving assembly arranged on the frame, and an up-and-down moving assembly arranged on the transverse moving assembly;

[0008] A material grabbing mechanism, the material grabbing mechanism comprising two groups of air gripper mounting seats spaced apart on the up-and-down moving assembly, air grippers correspondingly arranged on the air gripper mounting seats, and clamping jaw assemblies correspondingly arranged on the air grippers;

[0009] The clamping claw assembly includes two sets of mounting seats, mounting slots provided on the mounting seats, a rotating rod symmetrically mounted on the mounting slots and having an end that can slidably contact with the mobile phone frame, a resisting rod provided on the side of the rotating rod and capable of resisting with the mobile phone frame, and a limiting assembly provided in the mounting slots and limiting the rotation of the rotating rod;

[0010] When grabbing the material, the end of the rotating rod contacts the mobile phone frame and moves on the mobile phone frame, and then the resistance rod and the rotating rod pass through the area to resist, thereby clamping the mobile phone frame.

[0011] As an improvement, the transverse movement assembly includes a linear module and a transverse movement plate installed on the linear module and moving with the linear module.

[0012] As an improvement, the up and down moving assembly includes a movable plate set on the transverse plate for sliding up and down through several groups of linear slide rails, a cylinder mounting seat set on the transverse plate, a connecting seat set on the movable plate, a cylinder set on the cylinder mounting seat, and a floating joint set at the power output end of the cylinder and connected to the connecting seat.

[0013] As an improvement, the end of the rotating rod is made of flexible material and is arranged in a wedge shape.

[0014] As an improvement, the included angle between the rotating rod and the mounting seat is α, then 38.66°≤α≤85°.

[0015] As an improvement, the limit assembly includes a limit plate a arranged in the installation groove and capable of being resisted by the rotating rod, a pressing plate slidably arranged on the limit plate a, a spring arranged between the pressing plate and the bottom of the installation groove, a top rod arranged on the rotating rod and capable of being resisted by the pressing plate, and a limit plate b arranged on the other side of the rotating rod relative to the limit plate a and capable of being resisted by the rotating rod.

[0016] The beneficial effects of the utility model are:

[0017] (1) In the present invention, the end of the rotating rod contacts the frame of the mobile phone and then rotates. The end of the rotating rod moves on the surface of the mobile phone frame and brushes away the waste. Then, the resistance rod contacts the area brushed by the end of the rotating rod, and then the mobile phone frame is grasped, thereby ensuring the positioning accuracy and preventing indentations on the mobile phone frame.

[0018] (2) The two sets of air claws in the utility model cooperate with the corresponding clamping claw assembly, the lateral movement assembly and the up-and-down movement assembly to realize the loading and unloading of the mobile phone frame at the same processing station, thereby improving the processing efficiency of the mobile phone middle frame;

[0019] (3) In the present invention, two groups of air grippers are equipped with a total of four groups of resistance rods. When grasping, the four groups of resistance rods and the frame of the mobile phone form a four-point clamp. When clamping, the contact surface between the resistance rods and the frame of the mobile phone is small, thereby ensuring the clamping firmness while ensuring the clamping accuracy.

[0020] In summary, the utility model has the advantages of simple structure, high positioning accuracy and high grasping efficiency, and is particularly suitable for the field of mobile phone production equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Example:

[0030] like Figure 1 and Figure 2 As shown, a mobile phone frame automatic material grabbing device includes:

[0031] A transplanting mechanism 1, the transplanting mechanism 1 comprising a frame 11, a transverse moving assembly 12 arranged on the frame 11, and an up-and-down moving assembly 13 arranged on the transverse moving assembly 12;

[0032] The material grabbing mechanism 2 includes two groups of air gripper mounting seats 20 spaced apart on the up-and-down moving assembly 13, air grippers 21 correspondingly arranged on the air gripper mounting seats 20, and clamping jaw assemblies 22 correspondingly arranged on the air grippers 21;

[0033] The clamping claw assembly 22 includes two sets of mounting seats 220, mounting grooves 221 provided on the mounting seats 220, a rotating rod 222 symmetrically mounted on the mounting grooves 221 and having an end that can slidably contact the mobile phone frame 100, a resisting rod 223 disposed on the side of the rotating rod 222 and capable of resisting the mobile phone frame 100, and a limiting assembly 224 disposed in the mounting grooves 221 and limiting the rotation of the rotating rod 222;

[0034] When grabbing the material, the end of the rotating rod 222 contacts the mobile phone frame 100 and moves on the mobile phone frame 100, and then the rotating rod 222 contacts the contact rod 223 through the area, thereby clamping the mobile phone frame 100.

[0035] It should be noted that the model of the air gripper 21 is HDZ40-SG and the brand is Qilike.

[0036] What needs to be explained more is that Figure 3 As shown, the two groups of air grippers 21 cooperate with the transverse movement assembly 12 and the up and down movement assembly 13 to realize loading and unloading of materials at one workstation, thereby improving processing efficiency.

[0037] Furthermore, the transverse movement assembly 12 includes a linear module 121 and a transverse movement plate 122 installed on the linear module 121 and moving with the linear module 121 .

[0038] It should be noted that the linear die base 12 is CRS135-L-S300-O-M40-C4-C7B, and the brand is Jingyan.

[0039] Further, such as Figure 1 As shown, the up and down moving assembly 13 includes a moving plate 131 which is set on the transverse plate 122 for sliding up and down through a plurality of groups of linear slide rails, a cylinder mounting seat 132 set on the transverse plate 122, a connecting seat 133 set on the moving plate 131, a cylinder 134 set on the cylinder mounting seat 132, and a floating joint 135 which is set at the power output end of the cylinder 134 and connected to the connecting seat 133.

[0040] It should be noted that the cylinder 134 is a stroke-adjustable cylinder, model DNL-A50×100, brand Qilike, and the cylinder 134 allows the grasping position and the placing position to be adjusted up and down.

[0041] Furthermore, the end of the rotating rod 222 is made of flexible material and is wedge-shaped.

[0042] It should be noted that the end of the rotating rod 222 is made of flexible material, which ensures that the end of the rotating rod 222 will not scratch the mobile phone frame 100.

[0043] Furthermore, the included angle between the rotating rod 222 and the mounting seat 220 is α, and 38.66°≤α≤85°.

[0044] It should be noted that the angle between the rotating rod 222 and the mounting seat 220 ensures that the rotating rod 222 can rotate smoothly, and the end of the rotating rod 222 can scrape off the waste on the mobile phone frame 100.

[0045] It is also necessary to explain that the contact position between the abutment rod 223 and the mobile phone frame 100 is the position passed by the end of the rotating rod 222 , so that the abutment rod 223 clamps the mobile phone frame 100 without being affected by waste debris.

[0046] Furthermore, the limiting assembly 224 includes a limiting plate a2241 arranged in the mounting groove 221 and capable of being in contact with the rotating rod 222, a pressing plate 2242 slidably arranged on the limiting plate a2241, a spring 2243 arranged between the pressing plate 2242 and the bottom of the mounting groove 221, a top rod 2244 arranged on the rotating rod 222 and capable of being in contact with the pressing plate 2242, and a limiting plate b2245 arranged on the other side of the rotating rod 222 relative to the limiting plate a2241 and capable of being in contact with the rotating rod 222.

[0047] It should be noted that when the rotating rod 222 conflicts with the limiting plate b2245 , the rotating rod 222 is in an initial position; when the rotating rod 222 conflicts with the limiting plate a2241 , the conflicting rod 223 conflicts with the mobile phone frame 100 .

[0048] It should be further explained that the push rod 2244 is in an arc shape, thereby ensuring that the interference and cooperation effect between the push rod 2244 and the pressing plate 2242 is better.

[0049] It is important to note that the sliding fit between the pressing plate 2242 and the limiting plate a2241 is achieved through the cooperation of a T-slot and a T-block, which can effectively prevent the pressing plate 2242 from deflecting when moving. This cooperation method is a prior art and will not be elaborated on here.

[0050] Working process:

[0051] like Figure 4 and Figure 5 As shown, when clamping, the end of the rotating rod 222 contacts the mobile phone frame 100, and then the air claw 21 continues to drive the mounting seat 220 to continue to feed, and the rotating rod 222 rotates its end to slide across the side of the mobile phone frame 100, thereby removing the waste on the mobile phone frame 100, and as the mounting seat 220 continues to feed, the interference rod 223 contacts the end of the rotating rod 222 through the area, and then the mounting seat 220 continues to feed, and the rotating rod 222 contacts the limit plate a2241, and the four groups of the interference rods 223 grab the mobile phone frame 100; when releasing, the air claw 21 drives the mounting seat 220 to reset, and the spring 2243 drives the rotating rod 222 to reset.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
