Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone inspection tools, in particular to a flatness electric inspection mechanism and automatic electric inspection equipment. Background Art

[0002] With the advancement of mobile phone technology, phones are becoming thinner and their components are arranged more compactly. Consequently, the requirements for mobile phone components in production are naturally becoming increasingly stringent. For example, the flatness requirements for mobile phone mid-boards are also becoming increasingly stringent. Flatness is a key verification parameter for mobile phone mid-boards, used to detect deformation. The larger the flatness coefficient, the more severe the deformation. The distance parameter from each point to the ideal plane can be used to determine the location of the most severe deformation, allowing for verification.

[0003] When assembling a mobile phone, the LCD screen is installed on the front side of the mobile phone mid-plate, and the mobile phone battery is installed on the back side of the mobile phone mid-plate. Therefore, the flatness of the front side of the mobile phone mid-plate is required to be extremely high. If the mobile phone mid-plate is deformed, it is easy for the LCD screen and other electronic components to be squeezed against each other, causing water ripples on the LCD screen, and even causing gaps or warping on the edges of the mobile phone screen, resulting in poor product quality and increased product defective rate.

[0004] Currently, most companies still use manual inspection to detect the flatness of mobile phone mid-plates. This involves sliding a handheld slider across the corresponding area of ​​the mobile phone mid-plate and visually judging the flatness deformation based on the size of the gap using a feeler gauge. This inspection method is not only inefficient but also places high demands on the staff's work and is prone to misjudgment, leading to an increased product defect rate. Utility Model Content

[0029] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] The terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc. in the specification and claims of the present utility model indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the clarity of expressing the technical solutions and the convenience of description, and therefore cannot be understood as limiting the present application.

[0031] Example 1:

[0032] See also Figure 1 and Figure 2 A flatness electric inspection mechanism 1 is arranged on a workbench 50, and includes a detection unit 10, a lifting unit 20, a sorting unit 30 and a control unit 40. The lifting unit 20, the sorting unit 30 and the control unit 40 are respectively arranged on the workbench 50.

[0033] The detection unit 10 includes an upper mold assembly 11, a lower mold assembly 12 and a detector. The lower mold assembly 12 is used to position and place the workpiece. The upper mold assembly 11 and the lower mold assembly 12 are respectively installed on the lifting unit 20 and the sorting unit 30. The lifting unit 20 can drive the upper mold assembly 11 to move vertically, and the sorting unit 30 can drive the lower mold assembly 12 and the workpiece to move horizontally on the workbench 50. The upper mold assembly 11 and the lower mold assembly 12 can be closed to detect the flatness of the workpiece. The detector is used to calculate and analyze the detection data of the upper mold assembly 11 and the lower mold assembly 12.

[0034] See also Figure 3-Figure 6 The upper mold assembly 11 includes an upper mold base 111 and an upper mold detection block 112 arranged below the upper mold base 111. The upper mold detection block 112 and the upper mold base 111 are insulated from each other and the upper mold detection block 112 is electrically connected to the detector through a wire. The upper mold base 111 is provided with an upper mold limit block 113 protruding downward; the lower mold assembly 12 includes a lower mold base 121 and a lower mold detection block arranged above the lower mold base 121 122, the lower mold detection block 122 and the lower mold base 121 are insulated from each other and the lower mold detection block 122 is electrically connected to the detector through a wire, and the lower mold base 121 is provided with a lower mold limit block 123 protruding upward; when the upper mold assembly 11 and the lower mold assembly 12 are closed, the upper mold limit block 113 presses against the lower mold limit block 123 to leave a detection gap 13 between the upper mold detection block 112 and the lower mold detection block 122.

[0035] More specifically, the height of the detection gap 13 is equal to the sum of the workpiece thickness, the workpiece convexity tolerance, and the workpiece concavity tolerance. Therefore, the operator can adjust the height of the detection gap 13 by replacing the upper and lower mold detection blocks 112 and 122 with different thicknesses to meet different inspection accuracy requirements. The operator can also replace the upper and lower mold detection blocks 112 and 122 to meet the inspection requirements of different workpieces.

[0036] The control unit 40 is used to control the coordination among the detection unit 10 , the lifting unit 20 , and the sorting unit 30 .

[0037] When the flatness electric inspection mechanism 1 is working: the workpiece is positioned and placed on the lower mold inspection block 122 by manual or machine feeding; the sorting unit 30 transports the lower mold assembly 12 and the workpiece to the bottom of the upper mold assembly 11; the lifting unit 20 drives the upper mold assembly 11 to descend and approach the lower mold assembly 12. When the upper mold limit block 113 hits the lower mold limit block 123, the upper mold assembly 11 and the lower mold assembly 12 are closed. At this time, the detection gap 13 is left between the upper mold inspection block 112 and the lower mold inspection block 122; the upper mold inspection block 112 and the lower mold inspection block 122 are both in a conductive state. If the thickness of the workpiece is less than the height of the detection gap 13, the detector detects that the upper mold detection block 112 and the lower mold detection block 122 are not conductive to each other, thereby judging that the flatness of the workpiece meets the requirements and the workpiece is a qualified product; if the thickness of the workpiece is greater than the height of the detection gap 13, the upper mold detection block 112 and the lower mold detection block 122 form a conductive path through the workpiece, and the detector detects that the upper mold detection block 112 and the lower mold detection block 122 are conductive to each other, thereby judging that the flatness of the workpiece does not meet the requirements and the workpiece is a defective product; after the detection is completed, the lifting unit 20 drives the upper mold assembly 11 to rise and return to its original position. The control unit 40 controls the sorting unit 30 to sort the workpiece after inspection. If the workpiece is a qualified product, the sorting unit 30 transports the lower mold assembly 12 and the workpiece to a preset area, and then unloads the workpiece manually or by machine; if the workpiece is a defective product, the sorting unit 30 transports the lower mold assembly 12 and the workpiece to the preset area, and then unloads the workpiece manually or by machine for recycling.

[0038] From the above, the flatness electric inspection mechanism 1 proposed by the present invention, through the cooperation of the detection unit 10 and the lifting unit 20, realizes the replacement of manual flatness inspection of the workpiece, thereby reducing labor costs, improving detection efficiency and improving detection stability; through the cooperation of the upper mold assembly 11, the lower mold assembly 12, and the detector, it realizes automatic detection and determination of the flatness of the workpiece, thereby improving detection accuracy; through the cooperation of the detection unit 10, the sorting unit 30, and the control unit 40, it realizes automatic sorting of the workpiece after detection, thereby improving production efficiency. The flatness electric inspection mechanism 1 not only improves the detection efficiency and detection accuracy of the workpiece flatness, but also reduces labor costs and improves production efficiency.

The upper mold insulating member 114 prevents the upper mold detection block 112 from contacting the upper mold base 111 to achieve the purpose of insulation; the lower mold assembly 12 also includes a lower mold insulating member 124, which is arranged on the upper surface of the lower mold base 121, and the lower mold detection block 122 is arranged on the lower mold insulating member 124. The lower mold insulating member 124 prevents the lower mold detection block 122 from contacting the lower mold base 121 to achieve the purpose of insulation.

[0042] The upper die inspection block 112 is provided with a first avoidance groove 116 corresponding to the positioning post 126. The first avoidance groove 116 is used to avoid the positioning post 126. When the upper die assembly 11 and the lower die assembly 12 are closed, the positioning post 126 does not interfere with the upper die inspection block 112. The upper die inspection block 112 is provided with a second avoidance groove 117 corresponding to the workpiece.

[0046] Furthermore, the lifting assembly 22 also includes a pair of second rails 221 and a pair of second sliders 223. The second rails 221 are vertically fixed to the inner side surfaces of the two support plates 212, and the second sliders 223 are slidably mounted on the second rails 221. The second sliders 223 are connected to the lifting plates 222 via first connectors 224. The movable end of the first driving device 23 passes through the top plate 211 and is connected to the lifting plates 222. The first driving device 23 drives the lifting plates 222 to move up and down along the second rails 221, thereby driving the upper mold assembly 11 to ascend or descend.

[0047] See also Figure 2 and Figure 8 The sorting unit 30 includes a transfer assembly 31 located below the lifting plate 222. The transfer assembly 31 includes a pair of first slide rails 311 horizontally arranged on the workbench 50 and a movable plate 312 sliding on the pair of first slide rails 311. The movable plate 312 is located below the upper mold assembly 11, and the lower mold assembly 12 is installed on the upper surface of the movable plate 312.

The movable plate 312 is mounted on the pair of first sliders 313, and the second drive device 32 is connected to the movable plate 312 via a second connector 319. The second drive device 32 drives the movable plate 312 to move laterally along the first slide rails 311, thereby driving the lower mold assembly 12 and the workpieces to move laterally, thereby transporting the workpieces to the predetermined area for manual or machine unloading, thus achieving sorting.

[0049] See also Figure 8 and Figure 9 The transfer assembly 31 further includes a first sensor 314, a second sensor 315, and a third sensor 316.

The preset area includes a qualified area 34, a detection area 35, and a recovery area 36.

The detection unit 10 is located in the detection area 35.

[0050] Furthermore, the movable plate 312 is provided with a sensing block 318 that cooperates with the first sensor 314 , the second sensor 315 , and the third sensor 316 .

[0051] Before detection, the movable plate 312 drives the lower mold assembly 12 to move toward the detection area 35. When the second sensor 315 senses the sensing block 318, the control unit 40 controls the second driving device 32 to stop working to keep the movable plate 312 in the detection area 35. At this time, the lower mold assembly 12 is located directly below the upper mold assembly 11.

[0052] After detection, if the workpiece is qualified, the movable plate 312 drives the workpiece to move toward the qualified area 34. When the first sensor 314 senses the sensing block 318, the control unit 40 controls the second driving device 32 to stop working to keep the movable plate 312 in the qualified area 34, and then unloads the workpiece manually or by machine; if the workpiece is defective, the movable plate 312 drives the workpiece to move toward the recycling area 36. When the third sensor 316 senses the sensing block 318, the control unit 40 controls the second driving device 32 to stop working to keep the movable plate 312 in the recycling area 36, ​​and then unloads and recycles the workpiece manually or by machine, and finally completes the sorting.
