[0002] A stylus tester is a device specifically designed to test and evaluate the various performance indicators of styluses. In the digital age, styluses, as an important tool for human-computer interaction, are widely used in touchscreen devices such as tablets and smartphones. Stylus testers play a vital role in the production, quality control, and research and development of styluses. With the continuous development of touch technology and the increasing variety of stylus application scenarios, stylus testers are also constantly being updated and improved.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention uses a belt conveyor to transport the stylus body into a flow guide component. A stepping conveyor then transports multiple stylus bodies from the flow guide component to a push-out component. The push-out component pushes the stylus bodies into a placement component, which arranges them into an array. A transfer component then transfers the arrayed stylus bodies into corresponding pens in a loading frame. Finally, a robotic arm gripping mechanism uses a pre-set gripping path to grasp and test the stylus bodies in the pens. This automated loading process allows for the orderly placement of multiple stylus bodies into the pens in the loading frame, eliminating the need for manual insertion of each stylus body and significantly reducing the tediousness of manual loading, thus improving loading efficiency.

[0017] 2. This invention also features multiple semi-circular protrusions arranged on the top surface of the conveyor belt, forming a stylus placement area between every two semi-circular protrusions. Simply placing multiple stylus bodies onto the top surface of the conveyor belt and laying them flat allows for easy and orderly placement within the stylus placement area due to the arc-shaped structure of the semi-circular protrusions. The stylus bodies are then conveyed forward into the guide assembly via the conveyor belt. This method is particularly simple and quick compared to inserting stylus bodies one by one into the multiple pens in the feeding frame, further reducing the tediousness of manual operation.

[0018] 3. This invention also designs a flow guiding component, enabling the belt conveyor component to effectively transfer the stylus body into the stepping conveyor component. By setting a baffle on the side wall of the flow guiding plate, and connecting a limiting plate to the top surface of the baffle, the top surface of the flow guiding plate is designed with an arc surface structure. This ensures that the baffle can keep the stylus body centered on both sides of the flow guiding plate, preventing the stylus body from shifting position. The limiting plate can ensure that multiple stylus bodies are transported forward in a single layer, preventing multiple stylus bodies from stacking. The arc surface structure of the top surface of the flow guiding plate can effectively ensure that multiple stylus bodies slide forward automatically, improving the flow guiding effect of the flow guiding component.

[0019] 4. This invention also incorporates a push-out component and a placement component. The push-out component effectively advances multiple stylus bodies from the stepping conveyor component to the bottom of the placement component. When the push-out component pushes the stylus bodies upward, the push plate enters the side position between the two stacking blocks at the bottom of the conveyor belt. As the stacking rods at the bottom of the conveyor belt move upward, the two stacking blocks on their sidewalls gradually contact the bottom of the stylus bodies on the push plate, thereby causing the stylus bodies to leave the push plate. The stylus bodies are then supported by the two stacking blocks and move upward. Through repeated operation, the stacking blocks of the multiple stacking rods arrange the multiple stylus bodies into an array, forming a stacking effect for the multiple stylus bodies. This provides a more accurate alignment effect for the subsequent transfer component to transfer the stylus bodies to the multiple pen slots in the loading frame.

[0020] 5. This invention also designs a transfer assembly. The movable frame of the transfer assembly can slide back and forth in the support groove, and the lifting frame of the transfer assembly can move up and down inside the movable frame. The rotating plate of the transfer assembly has a horizontal state and a vertical state. In the vertical state, the rotating plate slides backward in the support groove via the movable frame, so that one end of multiple stylus bodies is inserted into the corresponding clamping channels on the rotating plate. The stylus bodies are clamped and fixed in the clamping channels by clamping plates. Then, the movable frame slides forward in the support groove, causing the vertical rotating plate to move away from the placement group. The rotating plate, through clamping plates in multiple clamping channels, lifts multiple arrayed stylus bodies from the placement assembly. Then, driven by a motor, the rotating plate rotates around a rotating column, making it horizontal. The lifting frame then descends within the moving frame, further lowering the horizontally positioned rotating plate. The rotating plate carries multiple stylus bodies into multiple pen slots in the loading frame, achieving automated loading and accurately placing multiple stylus bodies into multiple pen slots simultaneously, further improving work efficiency.

[0021] 6. This invention also incorporates a ring-tooth structure designed on the side wall of the rotating plate. After one end of each of the multiple stylus bodies is inserted into the corresponding clamping channels on the rotating plate, the hydraulic cylinder four operates to push multiple racks forward. The racks drive the ring teeth to rotate around the top surface of the fixed ring plate. During the rotation of the ring teeth, the three arc-shaped grooves on their top surface drive the corresponding three drive columns to move. The drive columns drive the clamping plates to slide forward on the sliding protrusion three. The three clamping plates slide into the clamping channels, clamping and fixing the stylus bodies. This ensures that the arrangement of the stylus bodies remains relatively stable when they are transferred, improving the reliability and stability of the transfer process.

[0050] Furthermore, the loading frame 2 includes a base plate 201, the top surface of which is connected to a top frame plate 203 via multiple fixing posts 202. A middle frame plate 204 is arranged between the base plate 201 and the top frame plate 203. The top frame plate 203 has multiple arrayed pen holes 205 arranged from top to bottom, and the middle frame plate 204 has multiple holes corresponding to the pen holes 205 arranged from top to bottom. The pen holes 205 are used to place the stylus body 8. The OK unloading frame 4 and NG unloading frame 5 are arranged with pen holes 205 of the same structure as the loading frame 2. The robotic arm gripping mechanism 6 is used to hold the pen holes 205. The stylus body 8 inside the loading frame 2 is grasped and moved to the flat testing mechanism 3. The robotic arm grasping mechanism 6 works to grasp the stylus body 8 in the pen hole 205 of the loading frame 2 and move it to the flat testing mechanism 3. The robotic arm grasping mechanism 6 simulates various motion paths so that the stylus body 8 can perform point and line tests on the flat testing mechanism 3. After the test is completed, the data is uploaded to the background computer mechanism and OK and NG are judged. The robotic arm grasping mechanism 6 places the stylus body 8 into the corresponding OK unloading frame 4 or NG unloading frame 5, and then repeats the material picking test operation.

[0051] In an embodiment of the present invention, the palletizing conveyor 7 includes a support platform 71. The top surface of the support platform 71 is provided with a belt conveyor assembly 72, a flow guiding assembly 73, a stepping conveyor assembly 74, an ejection assembly 75, a placement assembly 76, and a transfer assembly 77.

The stylus body 8 is placed on the top surface of the conveyor belt 7201. By simply laying the stylus body 8 flat, the stylus body 8 can be easily and orderly placed into the stylus placement area due to the arc surface structure of the top surface of the semi-circular convex strip 7202. Then, the stylus body 8 is conveyed forward into the guide component 73 by the conveyor belt 7201.

The top surface of the stepper plate 7413 is provided with multiple receiving blocks 7414. The top surface of the receiving block 7414 is set with an arc-shaped groove structure that matches the shape of the stylus body 8. The receiving block 7414 is used to drive the stylus body 8 to move forward between multiple conveying grooves 7403. The top surface of the fixed base 7404 is also provided with multiple fixed side plates 1 7415 and multiple fixed side plates 2 7416. The rotating rod 7406 is rotatably arranged on the side wall of the fixed side plate 1 7415. The shafts of the bevel gear 2 7408 and the sprocket 1 7409 pass through the side wall of the fixed side plate 2 7416 and are rotatably engaged with the side wall of the fixed side plate 2 7416. The sprocket 2 7411 is rotatably arranged between the two fixed side plates 2 7416.

[0057] This invention utilizes a motor 7405 to drive a rotating rod 7406 to rotate, which in turn drives two bevel gears 7407 to rotate.

This allows one end of each stylus body 8 to be inserted into a corresponding clamping channel on the rotating plate 7715. Then, a hydraulic cylinder 7717 operates, pushing multiple racks 7719 forward. The racks 7719 drive the ring teeth 7721 to rotate around the top surface of a fixed ring plate 7723. During the rotation of the gear 7721, the three arc-shaped grooves 7728 on its top surface drive the corresponding three drive columns 7727 to move.

Then, the moving frame 7703 slides forward in the support groove 7702, driving the vertically rotating plate 7715 to move away from the placement component 76. Multiple arrayed stylus bodies 8 are lifted from the placement assembly 76 by clamping plates 7726 within multiple clamping channels. Then, motor 7711 drives a rotating plate 7715 to rotate around a rotating column 7716, bringing the rotating plate 7715 to a horizontal position. Hydraulic cylinder 7710 then pushes and pulls, causing the lifting frame 7707 to descend within the moving frame 7703, further lowering the horizontally positioned rotating plate 7715. 5. The system moves multiple stylus bodies 8 into multiple pen holes 205 in the loading frame 2. The hydraulic cylinder 7717 operates, causing multiple racks 7719 to move backward, further causing the clamping plate 7726 to slide out of the clamping channel and lose its clamping effect on the stylus bodies 8. Then, the lifting frame 7707 moves upward inside the moving frame 7703, causing the rotating plate 7715 to rise. The multiple stylus bodies 8 remain in the multiple pen holes 205 in the loading frame 2, completing the automated loading operation.

[0066] Working Principle: This embodiment provides a stylus testing machine. In use, the stylus body 8 is conveyed into the flow guiding component 73 by the belt conveyor component 72. Multiple stylus bodies 8 in the flow guiding component 73 are conveyed to the top of the ejection component 75 by the stepping conveyor component 74. The ejection component 75 pushes the multiple stylus bodies 8 into the placement component 76. The placement component 76 arranges the multiple stylus bodies 8 into an array. Then, the transfer component 77 transfers the arrayed stylus bodies 8 to multiple phases of the loading frame 2. The stylus body 8 is finally picked up from the stylus cavity 205 in the loading frame 2 by the robotic arm gripping mechanism 6 and moved to the flat test mechanism 3. The robotic arm gripping mechanism 6 simulates various motion paths so that the stylus body 8 can be tested for point and line marking on the flat test mechanism 3. After the test is completed, the data is uploaded to the background computer mechanism and OK and NG are judged. The stylus body 8 is placed into the corresponding OK unloading box 4 or NG unloading box 5 by the robotic arm gripping mechanism 6, and then the material picking test operation is repeated.
