Description

Technical Field

[0002] Nowadays, with the continuous progress of mobile communication technology, the SIM card of mobile phones has gradually evolved from the earliest 25x15 mm standard SIM card to the current 12.3x8.8 mm Nano-SIM card. The SIM card slot designed specifically for Nano-SIM cards has quickly entered the market with advantages such as being smaller, more concealed, and integrated. Compared with the traditional mobile phone back cover slot, such slots usually require a mobile phone ejector pin for assisting in taking out and inserting the card.

[0003] Compared with the small Nano-SIM card, the equally small mobile phone ejector pin also has relatively high precision requirements during the production and detection process. The length of the mobile phone ejector pin is approximately 29.90 mm and the width is 7.29 mm. During the detection process, the needle tip needs to face outwards and inwards. During the automatic feeding, detection, and discharging process of the mobile phone ejector pin equipment, feeding, detection, and discharging stations need to be set on the equipment. Since the detection accuracy requirement reaches plus or minus 0.15 mm, it is necessary to ensure the stability of the ejector pin during detection to ensure the detection accuracy and avoid unnecessary scrapping of subsequent processes due to errors in size detection.

The detection mechanism 100 is installed on the top side surface of the conveying mechanism 200. When the needle to be detected is conveyed by the conveying mechanism 200, the detection mechanism 100 can detect the processing accuracy of the needle during the conveying process. Among them, the conveying mechanism 200 includes a conveying turntable 210 and a cover plate 220.

Compared with the traditional linear conveying type detection device, the detection device of the present utility model with a turntable conveying mechanism 10 greatly simplifies the equipment structure, can more effectively utilize the installation space, and improves the setting flexibility between equipment.

[0035] Specifically, the conveying turntable 210 is provided with a plurality of receiving grooves a, and the plurality of receiving grooves a are arranged along the circumferential direction of the conveying turntable 210, so that each receiving groove a can rotate relative to the cover plate 220 as the conveying turntable 210 rotates; the cover plate 220 is correspondingly provided with a plurality of detection grooves b for the receiving grooves a, and the plurality of detection grooves b are arranged on the cover plate 220 corresponding to the rotation track of the receiving grooves a, and each detection groove b penetrates from the top surface of the cover plate 220 to the bottom surface of the cover plate 220, so that the detection mechanism 100 can perform on-line detection of the pin needles in the plurality of receiving grooves a through the plurality of detection grooves b.

[0036] In one embodiment, the conveying turntable 210 is set to rotate intermittently for feeding. After the pin needles to be detected are loaded into the corresponding receiving grooves a, they rotate intermittently with the conveying turntable 210; when each receiving groove a rotates to the bottom side of the corresponding detection groove b, the conveying turntable 210 stops rotating for a preset time, so that the detection mechanism 100 can detect the pin needles in the receiving groove a through the detection groove b; after the detection is completed, the conveying turntable 210 starts again, so that the subsequent receiving groove a containing the pin needles to be detected rotates to the bottom side of the detection groove b. Based on this, the intermittent rotation and feeding of the conveying turntable 210 can better cooperate with the detection mechanism 100 to complete the on-line detection of the processing accuracy of the pin needles, while improving the automation degree of the pin needle detection process, effectively ensuring the effectiveness and accuracy of the on-line detection of the pin needles, and further improving the detection efficiency of the pin needles.

[0037] Furthermore, the cover plate 220 is correspondingly provided with a feeding detection station 221, a precision detection station 222 and a discharging station 223 for the detection mechanism 100. The feeding detection station 221, the precision detection station 222 and the discharging station 223 are arranged in sequence on the surface of the cover plate 220 along the rotation track of the receiving groove a; the two detection grooves b are respectively arranged at the feeding detection station 221 and the precision detection station 222. Specifically, each receiving groove a cooperates with the feeding detection station 221, the precision detection station 222 and the discharging station 223 in sequence during the rotation process, so that the detection mechanism 100 can perform corresponding item detection on the pin needles in the corresponding receiving groove a through the two detection grooves b at the feeding detection station 221 and the precision detection station 222. In one embodiment, the feeding detection station 221 is provided with a feeding baffle 2211. The feeding baffle 2211 is connected to the side edge of the cover plate 220 corresponding to the feeding station and can cooperate with the receiving groove a rotating to the feeding detection station 221 to close the feeding port of the receiving groove a corresponding to the feeding detection station 221 when the conveying mechanism 200 stops.

[0038] Further, the detection mechanism 100 includes a feeding detection unit 110 and a precision detection unit 120.

The position sensor is connected to the cover plate 220 through an optical fiber bracket and installed on the top side of the corresponding detection slot b to detect whether the card pins are fed in place; the precision detection unit 120 is set as a laser detection sensor. The laser detection sensor is installed on the top side of the corresponding detection slot b, and the corresponding detection slot b is set as a rectangular through hole to scan and record the card pins and check the card pin samples.

[0039] Further, the cover plate 220 is provided with a blanking slot c corresponding to the blanking station 223, and the blanking slot c penetrates to the corresponding receiving slot a; correspondingly, the conveying mechanism 200 further includes a blanking component 230. The blanking component 230 is disposed on the top side of the blanking slot c at the blanking station 223 on the top side of the cover plate 220, so that the blanking component 230 can blank the card pins in the corresponding receiving slot a to the external material receiving mechanism through the blanking slot c. Specifically, the blanking component 230 includes a driving cylinder 231 and a push rod 232. The driving cylinder 231 is installed on the surface of the cover plate 220; the push rod 232 cooperates with the blanking slot c and extends through to the receiving slot a at the bottom side. Moreover, the push rod 232 is connected to the end of the piston rod of the driving cylinder 231; the piston rod of the driving cylinder 231 drives the push rod 232 to reciprocate along the extending direction of the blanking slot c. When the card pins completed the detection in the conveying turntable 210 rotate with the corresponding receiving slot a to the bottom side of the blanking station 223, the driving cylinder 231 drives the push rod 232 to push the card pins out of the receiving slot a, thus completing the blanking work.

[0040] Further, the blanking component 230 further includes an abutting block 233 and a limiting baffle 234. The abutting block 233 is disposed on one side of the driving cylinder 231 and connected to the piston rod of the driving cylinder 231.

When the piston rod of the driving cylinder 231 extends a preset length, the abutting block 233 abuts against the limiting baffle 234, thereby limiting the output range of the driving cylinder 231.

[0041] Further, the conveying turntable 210 is further provided with a plurality of inlays 211, and the plurality of inlays 211 are respectively and correspondingly fitted into the plurality of receiving grooves a. Each inlay 211 can cooperate with the needle clamp to fix the needle clamp, so as to improve the detection accuracy of the detection mechanism 100 for the needle clamp in the receiving groove a. Specifically, each inlay 211 is provided with a matching groove d corresponding to the needle clamp, and the needle clamp is stably installed in the inlay 211 through the matching groove d.

[0042] Further, the conveying mechanism 200 further includes a support 240 and a driving motor 250. The driving motor 250 and the cover plate 220 are both installed on the support 240. Among them, the cover plate 220 is installed at the top of the support 240, the driving motor 250 is arranged on the bottom side of the cover plate 220, and the output end of the driving motor 250 faces the cover plate 220. Specifically, the conveying turntable 210 is connected to the output end of the driving motor 250, so that the driving motor 250 can drive the conveying turntable 210 to rotate relative to the cover plate 220.

[0043] Further, the conveying mechanism 200 further includes a speed reducer 260. The speed reducer 260 is arranged between the driving motor 250 and the conveying turntable 210, that is, the input end of the speed reducer 260 is connected to the output end of the driving motor 250, and the output end of the speed reducer 260 is connected to the conveying turntable 210, so as to reduce the rotation speed of the conveying turntable 210 and increase the torque.

Compared with the traditional linear conveying detection device, the detection device with a turntable conveying mechanism of the present utility model greatly simplifies the equipment structure, can make more effective use of the installation space, and improves the setting flexibility between devices. The conveying turntable is set to rotate intermittently for feeding. After the needle to be detected is loaded into the corresponding receiving groove, it rotates intermittently with the conveying turntable; when each receiving groove rotates to the bottom side of the corresponding detection groove, the conveying turntable stops rotating for a preset time, so that the detection mechanism can detect the needle in the receiving groove through the detection groove; after the detection is completed, the conveying turntable starts again, so that the subsequent receiving groove containing the needle to be detected rotates to the bottom side of the detection groove. Based on this, the intermittent rotation and feeding of the conveying turntable can better cooperate with the detection mechanism to complete the on-line detection of the machining accuracy of the needle, improve the automation degree of the needle detection process, effectively ensure the effectiveness and accuracy of the on-line detection of the needle, and further improve the detection efficiency of the needle.
