Description

Technical Field

[0001] This invention relates to the field of detection and sorting, and more particularly to a key detection and flipping system. Background Technology

[0002] With the widespread demand for electronic devices such as smartphones and tablets, testing the performance of features like buttons is a crucial step in ensuring product quality during the production process. Currently, common testing methods are limited. However, with the advancement of manufacturing automation and the difficulty in recruiting manpower, promoting automated testing is urgently needed; yet, there is currently no reliable automated method to achieve fully automated operations. Manual methods have significant limitations, severely hindering the realization of full-line automation.

[0003] Currently, there is no effective automated device to achieve automated inspection; relying solely on manual operation is not conducive to large-scale, fully automated production processes. When scanning and inspecting items, it is usually necessary to scan and inspect a specific side of the product. After inspection, the product needs to be flipped to the other side for processing at other workstations. Manual flipping is inefficient and cannot meet the requirements of automated production lines.

[0004] Therefore, the current button detection and flipping operation suffers from low automation, poor integration, and slow production cycle. Summary of the Invention

[0005] The purpose of this invention is to provide a key detection and flipping system. By integrating a translation drive module, a detection module, and a positioning and flipping module, it ensures continuous detection, shortens the idle travel time from key detection to flipping, and effectively improves production cycle time. The specific technical solution is as follows:

[0006] A key detection and flipping system includes a translation drive module, a detection module, and a positioning and flipping module movable on the translation drive module. The detection module is used to detect keys. The positioning and flipping module includes a detection area and corresponding fine positioning units and flipping units. The fine positioning unit includes a left fine positioning unit and a right fine positioning unit respectively disposed on both sides of the detection area. The distance between the left and right fine positioning units is adjustable. Both the left and right fine positioning units include bidirectional positioning components for clamping keys. The translation drive module can drive the keys on the left and right fine positioning units to correspond sequentially with the detection module. The flipping unit is disposed on the side of the fine positioning unit away from the detection module. The flipping unit includes corresponding left and right flipping units, with the left flipping unit corresponding to the left fine positioning unit and the right flipping unit corresponding to the right fine positioning unit. Both the left and right flipping units include clamping components, which are disposed close to the fine positioning units.

[0007] Furthermore, it also includes a movable support plate set on the translation drive module, with the detection area set on the side of the movable support plate close to the detection module, a right precision positioning unit fixed at one end of the movable support plate, and a right feeding platform on the right precision positioning unit corresponding to one side of the detection area. The left precision positioning unit includes a left precision drive component and a left feeding platform, with the left feeding platform corresponding to the right feeding platform. The left precision drive component is set at the other end of the movable support plate, and the left precision drive component can drive the left feeding platform to move towards the right feeding platform so that the left feeding platform corresponds to the other side of the detection area.

[0008] Furthermore, the bidirectional positioning assembly includes a positioning connecting block, a positioning bearing, and a lateral push head and a longitudinal push head disposed on adjacent sides of the positioning connecting block. The longitudinal push head is connected to the positioning connecting block through the positioning bearing to position the button disposed between the lateral push head and the longitudinal push head.

[0009] Furthermore, a slanted groove is formed on the positioning connecting block. One end of the slanted groove is located close to the lateral side push head, and the other end is located away from the lateral side push head. One end of the positioning bearing is connected to the slanted groove, and the other end is connected to the longitudinal positive push head.

[0010] Furthermore, the bidirectional positioning assembly also includes a side-push connecting block, a longitudinal spring, and a transverse spring. The side-push connecting block is mounted on the positioning connecting block. One end of the transverse spring is connected to the side-push connecting block, and the other end is connected to the transverse side-push pressure head. The longitudinal forward-push pressure head is connected to the positioning connecting block via the longitudinal spring.

[0011] Furthermore, it also includes a movable support plate set on the translation drive module, and a clamping assembly set on the movable support plate. The clamping assembly includes a flip base, a platform and a product positioning block set on the flip base respectively, and the product positioning block can be displaced in the direction of approaching or moving away from the precision positioning unit.

[0012] Furthermore, the clamping assembly also includes a stop block, a stop spring, a release bearing, and a side push block corresponding to the platform, all mounted on the platform. The product positioning block is located between the side push block and the stop block. One end of the product positioning block is connected to the side push block via the release bearing, and the other end is connected to the stop block via the stop spring.

[0013] Furthermore, it also includes a fixed base plate set on the movable support plate, with vertical positioning pins and horizontal positioning pins correspondingly set on the fixed base plate. Vertical limiting blocks and horizontal limiting blocks are correspondingly set on the side of the flip base near the fixed base plate. When the flip base rotates, the vertical positioning pins can stop the vertical limiting blocks, and the horizontal positioning pins can stop the horizontal limiting blocks.

[0014] Furthermore, the bidirectional positioning component also includes a first photoelectric switch and a first light-shielding plate. The first photoelectric switch is disposed on the side of the side push connecting block facing away from the lateral side push head, and the first light-shielding plate is disposed on the side push connecting block and is disposed corresponding to the first photoelectric switch.

[0015] Furthermore, it also includes a second photoelectric switch mounted on the movable carrier plate and a second light-shielding plate mounted on the flip base, with the second photoelectric switch and the second light-shielding plate being configured correspondingly.

[0016] The button detection and flipping system of the present invention has the following advantages:

[0017] 1. By integrating the translation drive module, detection module, and positioning and flipping module, the precision positioning unit is set up with a structure that is left and right corresponding and has bidirectional positioning components. At the same time, the clamping components of the flipping unit are set close to the precision positioning unit, which realizes a high degree of integration of detection and flipping functions. The translation drive module can drive the buttons on the left and right precision positioning units to correspond to the detection module in sequence, ensuring the continuity of detection. The design of the clamping components close to the precision positioning unit greatly shortens the idle travel time of the buttons from detection to flipping, effectively improving the production cycle time. It has the beneficial effects of high automation and high integration.

[0018] 2. A movable support plate is added, and the right precision positioning unit is fixed while the left precision positioning unit is made into a movable structure. The left feeding platform of the left precision positioning unit can move towards the right feeding platform, realizing flexible adjustment of the distance between the left and right precision positioning units. This provides sufficient working space for the external clamping device around the precision positioning unit and avoids equipment interference problems. At the same time, the detection area and the feeding platform are precisely aligned to ensure the accuracy when the button is moved to the detection position. With the drive of the translation drive module, the waiting time between the precision positioning unit and the detection module is reduced, further improving the flexibility and efficiency of the detection operation.

[0019] 3. The structure of the bidirectional positioning component is refined. The longitudinal push head is connected to the positioning connecting block through the positioning bearing. At the same time, the transverse push head and the longitudinal push head are configured to form a bidirectional clamp. With the help of the positioning bearing, the transverse and longitudinal positioning are synchronized, avoiding the cumulative error caused by step positioning and greatly improving the button positioning accuracy. Moreover, the contact method between the pressure head and the button is flexible linkage, rather than rigid push, which effectively prevents the button from being crushed during the positioning process, thus balancing positioning accuracy and product protection.

[0020] 4. An inclined groove is set on the positioning connecting block, and the positioning bearing connects the inclined groove to the longitudinal push head. The structure of the inclined groove allows the lateral displacement of the positioning connecting block to be converted into the longitudinal displacement of the longitudinal push head through the bearing, realizing synchronous and equal speed positioning of the lateral push head and the longitudinal push head, accurately controlling the displacement and force of bidirectional positioning, and ensuring that the button is subjected to uniform force during positioning. At the same time, the transmission method of the inclined groove simplifies the drive structure of bidirectional positioning, eliminating the need for two additional drive components, reducing the structural complexity and failure rate of the equipment.

[0021] 5. A side push connecting block and longitudinal and transverse springs are added to the bidirectional positioning component. The transverse and longitudinal springs provide buffering force for the side push connecting block and the longitudinal push head, avoiding button deformation or damage caused by rigid positioning. They also drive the pressure head to automatically return to its original position when the positioning drive component is reset, eliminating the need for additional reset sensors or drive components and simplifying the control logic. At the same time, the tension of the springs can maintain a stable clamping force between the pressure head and the button, preventing the button from shifting after positioning, and further improving the reliability and stability of positioning.

[0022] 6. The clamping assembly is mounted on the movable support plate and is structured to include a flip base, a stage, and a movable product positioning block. The product positioning block can move towards or away from the precision positioning unit, adapting to the clamping requirements of buttons of different sizes and enhancing the versatility of the equipment. The clamping assembly and the precision positioning unit are mounted on the movable support plate, realizing the linkage between the detection and flipping modules. When the external clamping device moves the detected button to the clamping assembly, there is no need for long-distance displacement, shortening the empty travel of the transfer. The flip base and the stage provide stable flipping support for the button, ensuring the positional accuracy of the button during the flipping process.

[0023] 7. By setting a servo motor to drive the rotation of the flipping unit, on the one hand, with precise angle control and torque feedback capabilities, in conjunction with the vertical positioning pin, horizontal positioning pin and corresponding limit block in the device, the button can be accurately flipped 90° from the horizontal state to the vertical state. When the limit block contacts the positioning pin and reaches the set torque value, the motor can immediately brake and clamp, completely avoiding the problems of low angle control accuracy and easy flipping deviation of traditional motors, ensuring that the button is in the same position after flipping, meeting the needs of subsequent workstation docking; on the other hand, its built-in self-locking function can firmly lock the flipping base when the motor stops, preventing the flipping component from rotating accidentally due to brake failure or the brake not being in place, avoiding the drop and damage of precision parts such as mobile phone buttons; at the same time, it can be seamlessly linked with the device's automated control system, flexibly adjusting the flipping speed and start / stop timing according to the working rhythm of the external clamping device, adapting to continuous automated operation on the production line without manual intervention, further improving the overall production cycle.

Detailed Implementation

[0038] To better understand the purpose, structure, and function of this invention, the key detection and flipping system of this invention will be described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 13 As shown, Figure 1 In the three-dimensional coordinate system shown, the +X direction is defined as the right of the device, the -X direction is defined as the left of the device, the +Y direction is defined as the back of the device, the -Y direction is defined as the front of the device, the +Z direction is defined as the top of the device, the -Z direction is defined as the bottom of the device, the X-axis is the horizontal direction, the Y-axis is the vertical direction, and the Z-axis is the vertical direction.

[0040] This invention provides a button detection and flipping system, which can be used to detect the performance of buttons and other products on mobile devices such as mobile phones. The device includes a translation drive module, a detection module 3 and two sets of positioning and flipping modules 4 disposed on the translation drive module. Each positioning and flipping module 4 includes a corresponding fine positioning unit and a flipping unit. The fine positioning unit performs horizontal and vertical positioning of the product under test through the cooperation of a drive component, a fixing component and an elastic component, which ensures positioning accuracy and prevents rigid positioning from damaging the product. The flipping unit flips the finely positioned product at a specific angle through a self-locking drive structure. In this embodiment, the product is rotated 90° from the horizontal direction to the vertical direction, without having to move the product to a separate flipping device, reducing the idle travel of cross-module transfer, and thus improving detection efficiency.

[0041] The translation drive module includes a bottom carrier 1, an X-axis moving module 2 extending laterally on the bottom carrier 1, and two sets of positioning and flipping modules 4 arranged sequentially on the front and rear sides of the moving support plate 5 of the X-axis moving module 2, having the same structure. The drive end of the X-axis moving module 2 is correspondingly located on both sides of the bottom carrier 1 with the detection module 3. Thus, the X-axis moving module 2 can drive the positioning and flipping modules 4 to move to the working area corresponding to the detection module 3, providing a unified spatial reference for the independent operation of the two modules and avoiding additional idle travel caused by the initial dispersion of the two modules.

[0042] Specifically, the precision positioning unit of the positioning and flipping module 4 includes a left precision positioning unit 100 and a right precision positioning unit 200, both of which include bidirectional positioning components. The two bidirectional positioning components are arranged in a mirror-symmetrical manner and are used to hold the buttons. The left precision positioning unit 100 and the right precision positioning unit 200 can be separately arranged to correspond with the detection area, that is, the distance between the left precision positioning unit 100 and the right precision positioning unit 200 is adjustable, thereby providing working space for the external gripping device around the precision positioning unit. In turn, the translation drive module can drive the buttons on the left precision positioning unit 100 and the right precision positioning unit 200 to correspond to the detection module 3 in sequence, so as to reduce the idle travel and waiting time between the flipping unit and the precision positioning unit.

[0043] Preferably, the positioning and flipping module 4 further includes a movable support plate 5 disposed on the X-axis moving module 2. A groove-shaped detection area is disposed on the side of the movable support plate 5 near the detection module 3. By moving the X-axis moving module 2, the detection area is moved in the lateral direction, so that the button to be tested is aligned with the detection optical path. The right precision positioning unit 200 is fixed on the right end of the movable support plate 5. The right feeding platform 220 on the right precision positioning unit 200 is correspondingly disposed on the right side of the detection area. The left precision positioning unit 100 includes a left precision drive component and a left feeding platform 120. The left feeding platform 120 is connected to the right feeding platform 200. The material platforms 220 are correspondingly positioned in the transverse direction of the detection area. The left precision drive component is located at the left end of the movable support plate 5. The left precision drive component can drive the left feeding platform 120 to move towards the right feeding platform 220, so that the left feeding platform 120 is corresponding to the left side of the detection area. That is to say, the right feeding platform 220 is always corresponding to the detection area. When detection is required, the left feeding platform 120 can be moved above the detection area. When detection is not required, it can be moved away from the right precision positioning unit 200, thus forming an interval space between the left precision positioning unit 100 and the right precision positioning unit 200. The movable support plate 5 is also provided with a fixed base plate 7. The front side of the fixed base plate 7 is provided with a groove structure corresponding to the detection area.

[0044] Furthermore, the left precision positioning unit 100 includes a first carrier mounting plate 101 and a bidirectional positioning assembly disposed on the fixed base plate 7. The left precision drive assembly includes a left precision cylinder 102 and a buffer assembly. The left precision cylinder 102 is disposed on the left side of the fixed base plate 7 and is connected to the first carrier mounting plate 101 via a floating mounting plate. The bidirectional positioning assembly is disposed on the first carrier mounting plate 101, thereby enabling the left precision cylinder 102 to drive the left unloading platform 120 to perform lateral displacement on the fixed base plate 7. The left precision cylinder 102 is fixed to the first cylinder fixing block 103 by bolts, and the guide rod of the left precision cylinder 102 is locked to the cylinder floating mounting block 104 by its own threads. A buffer assembly connected to the left precision cylinder 102 is also provided below the first vehicle mounting plate 101. The buffer assembly includes a buffer blocking block 107 and a guide rail support plate 108, which are fixed to the first vehicle mounting plate 101 by bolts. The guide rail of the first linear guide rail 131 is fixed to the guide rail support plate 108 by bolts. The slider of the first linear guide rail 131 is fixed to the bottom of the first vehicle mounting plate 101 by bolts. The first buffer 105 and the second buffer 106 are fixed to the buffer mounting block 109 in the opposite direction by their own nuts, which serve as a limit.

[0045] Preferred, such as Figure 6 and Figure 7 As shown, the bidirectional positioning component of the left precision positioning unit 100 includes a first positioning connecting block 110, a first positioning bearing 114, a first lateral side push head 111 disposed on the front side of the first positioning connecting block 110, and a first longitudinal forward push head 112 disposed on the right side of the first positioning connecting block 110. The first longitudinal forward push head 112 is connected to the right side of the first positioning connecting block 110 through the first bearing mounting block 113 and the first positioning bearing 114 in sequence, so as to position the first button 115 disposed between the first lateral side push head 111 and the first longitudinal forward push head 112. The first longitudinal forward push head 112 is used to clamp the long side of the first button 115, and the first lateral side push head 111 is used to clamp the short side of the first button 115.

[0046] Furthermore, a 45° inclined groove is formed on the first positioning connecting block 110. One end of the inclined groove is located close to the first lateral push head 111, pointing to the left front of the device, and the other end is located away from the first lateral push head 111, pointing to the right rear of the device. The lower end of the first positioning bearing 114 is connected to the inclined groove, and the upper end is connected to the first longitudinal push head 112. The first positioning cylinder 116 is fixed to the first cylinder pad 117 by bolts, and the first positioning floating joint 118 is locked to the guide rod of the first positioning cylinder 116. The first positioning connecting block 110 is fixed to the second linear guide rail 119 by bolts, and its left end is locked with the first positioning floating joint 118. Thus, when the first positioning connecting block 110 moves to the right, the first lateral push head 111 and the first longitudinal push head 112 move simultaneously to the left feeding table 120 to clamp the product, thereby improving the detection efficiency.

[0047] Furthermore, the bidirectional positioning assembly also includes a first side-push connecting block 121, a first longitudinal spring 122, and a first transverse spring 123. The first side-push connecting block 121 is embedded in the groove on the front side of the first positioning connecting block 110, and the lower part of the first side-push connecting block 121 is fixed on the slider of the eighth linear guide rail 128. One end of the first transverse spring 123 is connected to the first side-push connecting block 121, and the other end is connected to the first transverse side-push head 111. The first longitudinal positive push head 112 is connected to the front side of the first positioning connecting block 110 through the first longitudinal spring 122. The first longitudinal spring 122 is stuck in the spring groove of the first bearing mounting block 113 and the first spring mounting block 129. The two ends of the first transverse spring 123 are embedded in the grooves at corresponding positions. The first longitudinal spring 122 and the first transverse spring 123 provide corresponding tension buffers and at the same time provide a reset traction force for the first side-push connecting block 121 and the first longitudinal positive push head 112.

[0048] Furthermore, the bidirectional positioning assembly also includes a left first photoelectric switch 124 and a left first light shield 125. The left first photoelectric switch 124 is located on the side of the first side push connecting block 121 facing away from the first lateral side push head 111 and is fixedly connected to the first carrier mounting plate 101. The left first light shield 125 is located on the left side of the first side push connecting block 121 and is correspondingly arranged with the left first photoelectric switch 124.

[0049] Furthermore, it also includes a first X-direction lateral push blocking block 126 and a first Y-direction forward push blocking block 127. The first Y-direction forward push blocking block 127 and the ninth linear guide rail 130 are both fixed to the first carrier mounting plate 101 by bolts. The first X-direction lateral push blocking block 126 is correspondingly set with the first lateral push connecting block 121 to limit the leftward movement of the first lateral push connecting block 121. The first Y-direction forward push blocking block 127 is correspondingly set with the first longitudinal forward push pressure head 112 to limit the rightward movement of the first longitudinal forward push pressure head 112. Thus, the first longitudinal spring 122 and the first transverse spring 123 provide reset power, while the blocking block provides the reset endpoint, forming a simple, reliable and low-cost flexible reset mechanism that can automatically reset without sensor control, improving the system's response speed and reliability.

[0050] Preferred, such as Figure 8 and Figure 9 As shown, the bidirectional positioning assembly of the right precision positioning unit 200 includes a second positioning connecting block 210, a second positioning bearing 214, a second lateral push head 211 disposed on the front side of the second positioning connecting block 210, and a second longitudinal push head 212 disposed on the left side of the second positioning connecting block 210. The second longitudinal push head 212 is connected to the right side of the second positioning connecting block 210 through the second bearing mounting block 213 and the second positioning bearing 214 in sequence to position the second button 215 disposed between the second lateral push head 211 and the second longitudinal push head 212. The second longitudinal push head 212 is used to clamp the long side of the second button 215, and the second lateral push head 211 is used to clamp the short side of the second button 215. The third linear guide rail 230 and the fourth linear guide rail 231 are both fixed to the second carrier mounting plate 201 by bolts so that the second bearing mounting block 213 and the second positioning connecting block 210 can slide.

[0051] Furthermore, a 45° inclined groove is formed on the second positioning connecting block 210. One end of the inclined groove is located close to the second lateral side push head 211, pointing to the right front of the device, and the other end is located away from the second lateral side push head 211, pointing to the left rear of the device. The lower end of the second positioning bearing 214 is connected to the inclined groove, and the upper end is connected to the second longitudinal positive push head 212. The second positioning cylinder 216 is fixed to the second cylinder pad 217 by bolts, and the second positioning floating joint 218 is locked to the guide rod of the second positioning cylinder 216. The second positioning connecting block 210 is fixed to the fifth linear guide rail 219 by bolts, and its right end is locked to the second positioning floating joint 218. Thus, when the second positioning connecting block 210 moves to the right, the second lateral side push head 211 and the second longitudinal positive push head 212 move simultaneously to the right feeding table 220 to clamp the product, thereby improving the detection efficiency.

[0052] Furthermore, the bidirectional positioning assembly also includes a second side-push connecting block 221, a second longitudinal spring 222, and a second transverse spring 223. The second side-push connecting block 221 is embedded in a groove on the front side of the second positioning connecting block 210. One end of the second transverse spring 223 is connected to the second side-push connecting block 221, and the other end is connected to the second transverse side-push head 211. The second longitudinal positive push head 212 is connected to the front side of the second positioning connecting block 210 through the second longitudinal spring 222. The two ends of the second longitudinal spring 222 and the second transverse spring 223 are embedded in grooves at corresponding positions. The second longitudinal spring 222 and the second transverse spring 223 provide corresponding tension buffers and at the same time provide reset traction force for the second side-push connecting block 221 and the second longitudinal positive push head 212.

[0053] Furthermore, the bidirectional positioning assembly also includes a right first photoelectric switch 224 and a right first light shield 225. The right first photoelectric switch 224 is located on the side of the second side push connecting block 221 facing away from the second lateral side push head 211 and is fixedly connected to the second carrier mounting plate 201. The second carrier mounting plate 201 is fixed to the upper end of the carrier support plate 228 by bolts. The right first light shield 225 is located on the left side of the second side push connecting block 221 and is correspondingly arranged with the right first photoelectric switch 224.

[0054] Furthermore, it also includes a second X-direction lateral push blocking block 226 and a second Y-direction forward push blocking block 227. The second spring mounting block 229 is fixed to the upper end of the second Y-direction forward push blocking block 227 by bolts. The second X-direction lateral push blocking block 226 is correspondingly set with the second lateral push connecting block 221 to limit the rightward movement of the second lateral push connecting block 221. The second Y-direction forward push blocking block 227 is correspondingly set with the second longitudinal forward push pressure head 212 to limit the leftward movement of the second longitudinal forward push pressure head 212. Thus, the second longitudinal spring 222 and the second transverse spring 223 provide reset power, while the blocking block provides the reset endpoint, forming a simple, reliable and low-cost flexible reset mechanism that can automatically reset without sensor control, improving the system's response speed and reliability.

[0055] Preferred, such as Figures 10 to 13 As shown, the flipping unit includes a left flipping unit 300 and a right flipping unit 400 arranged horizontally. The left flipping unit 300 is arranged corresponding to the left precision positioning unit 100, and the right flipping unit 400 is arranged corresponding to the right precision positioning unit 200. Of course, it can be understood that after the product on the precision positioning unit is inspected, it can be moved to the left flipping unit 300 or the right flipping unit 400 by an external clamping device, without having to move according to the above-mentioned corresponding positions, thus improving the flexibility and collaborative efficiency of the inspection operation.

[0056] Specifically, a plate-shaped first fixed base plate 301 is arranged horizontally on the fixed base plate 7. The left flipping unit 300 includes a first flipping servo motor 302 and a clamping assembly connected together, and a first flipping cylinder 303 corresponding to the first flipping servo motor 302. The first flipping servo motor 302 and the first flipping cylinder 303 are both located on the rear side of the first fixed base plate 301, and the clamping assembly is located on the front side of the first fixed base plate 301. The clamping assembly includes a first flip base 304, a first platform 305 and a first product positioning block 306 correspondingly disposed on the first flip base 304. The first platform 305 is fixed on the side of the first flip base 304 near the first fixed base plate 301. The first product positioning block 306 can be longitudinally displaced toward or away from the precision positioning unit. Thus, after the external clamping device removes the product from the precision positioning unit, it can directly move the product backward to the first platform 305 for placement. The first product positioning block 306 moves toward the first platform 305 to complete the re-clamping of the product, reducing unnecessary actions such as reversing and improving the work efficiency between the detection and flipping steps.

[0057] Furthermore, the clamping assembly also includes a first stop block 307, a stop spring, a release bearing, and a first side push block 308 disposed on the right side of the first platform 305. The first stop block 307 is disposed at the end of the clamping assembly away from the first fixed base plate 301. The first product positioning block 306 is disposed between the first side push block 308 and the first stop block 307. The rear end of the first product positioning block 306 is detachably connected to the first side push block 308 through the release bearing, and the front end is connected to the first stop block 307 through the stop spring. That is, the first product positioning block 306 can remain in abutment state under the action of the stop spring. When the first tilting cylinder 303 drives the first side push block 308 to move forward, the first side push block 308 can drive the first product positioning block 306 to separate from the first platform 305 to place or remove the product.

[0058] Furthermore, a first vertical positioning pin 309 and a first horizontal positioning pin 310 are correspondingly provided on the side of the first fixed base plate 301 facing the clamping assembly. A first vertical limiting block 311 and a first horizontal limiting block 312 are correspondingly provided on the side of the first flipping base 304 near the first fixed base plate 301. The first vertical limiting block 311 and the first horizontal limiting block 312 are both located between the first vertical positioning pin 309 and the first horizontal positioning pin 310. When the first flipping servo motor 302 drives the first flipping base 304 to rotate, the first vertical positioning pin 309 can stop the first vertical limiting block 311, and the first horizontal positioning pin 310 can stop the first horizontal limiting block 312, thereby enabling the product to be accurately flipped from the horizontal position to the vertical position.

[0059] It is particularly important to emphasize that the first flip servo motor 302 achieves precise angular positioning and self-locking of the clamping component through the built-in torque of the first vertical limit block 311 and the first horizontal limit block 312, preventing brake failure or failure of the holding brake to be in place.

[0060] Furthermore, the device also includes two left second photoelectric switches 313 arranged side-by-side on the fixed base plate 7, and the two left second photoelectric switches 313 are arranged side-by-side on the photoelectric fixing block 315. The device also includes two left second light-shielding plates 314 arranged on the first flip base 304, the two left second light-shielding plates 314 being staggered one in front of the other on the arc-shaped surface of the first flip base 304, and the left second photoelectric switches 313 and left second light-shielding plates 314 being correspondingly arranged to achieve precise positioning of the rotation of the flip unit. The device also includes a left third photoelectric switch 317 arranged above the first fixed base plate 301, and a left third light-shielding plate 318 arranged above the first side push block 308, the left third photoelectric switch 317 and left third light-shielding plate 318 being correspondingly arranged to achieve precise positioning of the longitudinal movement of the first side push block 308. It is understood that those skilled in the art can select the number of photoelectric switches and light-shielding plates according to the actual situation.

[0061] Correspondingly, the right flip unit 400 is located to the right of the left flip unit 300, and the two are arranged in the same direction. The right flip unit 400 includes a second flip servo motor 402 and a clamping assembly connected together, and a second flip cylinder 403 corresponding to the second flip servo motor 402. The second flip servo motor 402 and the second flip cylinder 403 are both arranged on the rear side of the second fixed base plate 401. The second flip cylinder 403 is fixed on the second cylinder fixing block 425, and the clamping assembly is arranged on the front side of the second fixed base plate 401. The clamping assembly includes a second flip base 404, a second platform 405 and a second product positioning block 406 correspondingly disposed on the second flip base 404. The second platform 405 is fixed on the side of the second flip base 404 near the second fixed base plate 401. The second product positioning block 406 can be longitudinally displaced toward or away from the precision positioning unit. Thus, after the external clamping device removes the product from the precision positioning unit, it can directly move the product backward to the second platform 405 for placement. The second product positioning block 406 moves toward the second platform 405 to complete the re-clamping of the product, reducing unnecessary actions such as reversing and improving the work efficiency between the inspection and flipping steps.

[0062] Furthermore, the clamping assembly also includes a second stop block 407, a stop spring, a release bearing, and a second side push block 408 disposed on the second platform 405. The second stop block 407 is disposed at the end of the clamping assembly away from the second fixed base plate 401. The second product positioning block 406 is disposed between the second side push block 408 and the second stop block 407. The rear end of the second product positioning block 406 is detachably connected to the second side push block 408 via the release bearing, and the front end is connected to the second stop block 407 via the stop spring. That is, the second product positioning block 406 can remain in abutment state under the action of the stop spring. When the second tilting cylinder 403 drives the second side push block 408 to move forward, the second side push block 408 can drive the second product positioning block 406 to separate from the second platform 405 to place or remove the product.

[0063] Furthermore, a second vertical positioning pin 409 and a second horizontal positioning pin 410 are correspondingly provided on the side of the second fixed base plate 401 facing the clamping assembly. A second vertical limiting block 411 and a second horizontal limiting block 412 are correspondingly provided on the side of the second flipping base 404 near the second fixed base plate 401. The second vertical limiting block 411 and the second horizontal limiting block 412 are both located between the second vertical positioning pin 409 and the second horizontal positioning pin 410. When the second flipping servo motor 402 drives the second flipping base 404 to rotate, the second vertical positioning pin 409 can stop the second vertical limiting block 411, and the second horizontal positioning pin 410 can stop the second horizontal limiting block 412, thereby enabling the product to be accurately flipped from the horizontal position to the vertical position.

[0064] It is particularly important to emphasize that the second tilting servo motor 402 achieves precise angular positioning and self-locking of the clamping component through the built-in torque of the second vertical limit block 411 and the second horizontal limit block 412, preventing brake failure or failure of the holding brake to be in place.

[0065] Furthermore, the device also includes two right second photoelectric switches 413, one on the left and one on the right, mounted on the fixed base plate 7. One right second photoelectric switch 413 is mounted on the sensing photoelectric base 415, and the other right second photoelectric switch 413 is mounted on the sensor front and rear adjustment block 416 for position adjustment. The device also includes two right second light-shielding plates 414 mounted on the second flip base 404. The two right second light-shielding plates 414 are offset one in front of the other on the arc-shaped surface of the second flip base 404. The right second photoelectric switches 413 and right second light-shielding plates 414 are correspondingly arranged to achieve precise positioning of the flip unit rotation. The device also includes a right third photoelectric switch 417 mounted above the second fixed base plate 401, and a right third light-shielding plate 418 mounted above the second side push block 408. The right third photoelectric switch 417 and right third light-shielding plate 418 are correspondingly arranged to achieve precise positioning of the longitudinal movement of the second side push block 408. It is understood that those skilled in the art can select the number of photoelectric switches and light-shielding plates according to actual conditions.

[0066] like Figure 2 As shown, the X-axis moving module 2 includes a front guide rail support 8, a front linear guide rail 9, a lead screw module adapter block 10, a moving servo motor 11, a rear guide rail support 12, a rear linear guide rail 13, a lead screw module 14, and a lead screw module support 15. The lead screw module support 15 is directly fixed to the bottom carrier 1 with bolts. The front guide rail support 8 and the rear guide rail support 12 are arranged opposite each other on both sides of the lead screw module 14, and both are also fixed to the bottom carrier 1 with bolts. The front linear guide rail 9 is fixed to the front guide rail support 8 with bolts, and the rear linear guide rail 13 is fixed to the rear guide rail support 12 with bolts. The front linear guide rail 9 and the rear linear guide rail 13 are kept parallel to each other, providing smooth guidance for the reciprocating movement of the subsequent moving support plate 5. The lead screw module 14, which serves as the power transmission component, is doubly fixed to the lead screw module support 15 by bolts and positioning pins. The lead screw module adapter block 10 is connected to the flange end of the lead screw module 14. The moving servo motor 11 is fixed to the lead screw module adapter block 10 by bolts. The rotational power output by the moving servo motor 11 can be converted into linear motion by the lead screw module 14. With the guidance of the double linear guide rails, the moving support plate 5 can be moved smoothly and accurately, thereby providing overall coarse positioning drive for the two sets of positioning and flipping modules 4 installed on the moving support plate 5.

[0067] like Figure 4As shown, the button detection module 3 includes a detection camera 16, a camera fixing block 17, a lens pressure plate 18, a support block 19, a light source 20, a triangular prism 21, a prism fixing plate 22, a prism front and rear adjustment block 23, a prism left and right adjustment block 24, a lens 25, a detection fixing base plate 26, and a camera horizontal fixing plate 27. There are two button detection modules 3, which correspond to two sets of positioning and flipping modules 4, and both are fixed to the bottom carrier 1 by the detection fixing base plate 26. The camera horizontal fixing plate 27 is first fixed to the detection fixing base plate 26 with bolts. The camera fixing block 17 is then installed in the groove of the camera horizontal fixing plate 27 and tightened. The detection camera 16 and the support block 19 are respectively fixed at both ends of the camera fixing block 17. The lens 25 is fixed in the groove of the support block 19 with the help of the lens pressure plate 18 to ensure that the light path of the lens and the detection camera 16 are accurately aligned. At the same time, the triangular prism 21 is installed through the prism fixing plate 22 and, together with the prism front and rear adjustment block 23 and the prism left and right adjustment block 24, the position is finely adjusted to adapt to the detection light path requirements. The light source 20 provides sufficient and uniform light for detection. Finally, the detection camera 16 completes the detection of product QR codes and other information.

[0068] Furthermore, such as Figure 5 As shown, the device also includes an ion fan 6 mounted on the movable support plate 5. The ion fan 6 is positioned on the left side of the positioning and flipping module 4 and blows air to the right to efficiently and safely eliminate static electricity generated by the product and fixture during positioning detection and flipping operation, clean the dust on the surface of the electronic product, and prevent the product from adsorbing dust and lint.

[0069] The operating steps of this device are as follows:

[0070] During testing, the product to be tested is first placed on the left feeding platform 120 and the right feeding platform 220 of the precision positioning component using an external clamping device. After placement, the device will first perform product positioning. The operation process of this part is briefly described in the order of left precision positioning unit 100, right precision positioning unit 200, left flipping unit 300 and right flipping unit 400.

[0071] In the left precision positioning unit 100, after the product is placed, the first positioning cylinder 116 is activated, its guide rod extends, and pushes the first positioning connecting block 110 to move to the right. At the same time, it drives the first bearing mounting block 113 to move forward and the first side push connecting block 121 to move to the right, overcoming the tension of the first longitudinal spring 122 and the first transverse spring 123, forcing the first longitudinal positive push head 112 and the first transverse side push head 111 to position the product to be tested. After positioning is completed, the left precision cylinder 102 is activated, its guide rod extends, and pushes the first carrier mounting plate 101 to move to the right as a whole until the second buffer 106 reaches the limit position. At this time, the part of the product to be tested is exposed in the empty part of the fixed base plate 7. The empty part is set to correspond to the detection area, and then it is moved to the camera scanning position through the lead screw module 14 for easy scanning and detection by the camera. After the test is completed, the guide rod of the left precision cylinder 102 retracts, and the first carrier mounting plate 101 moves to the left as a whole until the first buffer 105 reaches the limit position. Then, the guide rod of the first positioning cylinder 116 retracts, and the first longitudinal positive push head 112 and the first transverse side push head 111 release the product to be tested, waiting for the external clamping device to clamp the product on it to the left flipping unit 300 or the right flipping unit 400 for positioning and flipping.

[0072] In the right precision positioning unit 200, after the product is placed, the second positioning cylinder 216 is activated, its guide rod extends, and pushes the second positioning connecting block 210 to move to the left. At the same time, it drives the second bearing mounting block 213 to move forward and the second side push connecting block 221 to move to the left, overcoming the tension of the second longitudinal spring 222 and the second transverse spring 223, forcing the second longitudinal positive push head 212 and the second transverse side push head 211 to position the product to be tested. After positioning, it is moved to the camera scanning position by the lead screw module 14 for detection. After detection, the guide rod of the second positioning cylinder 216 retracts, and the second longitudinal positive push head 212 and the second transverse side push head 211 release the product to be tested, waiting for the external clamping device to clamp the product on it to the left flipping unit 300 or the right flipping unit 400 for positioning and flipping.

[0073] The overall structure of the left flip unit 300 and the right flip unit 400 is the same. The initial position should be as shown in the right flip unit 400, with the product in a horizontal state. The completed flip position should be as shown in the left flip unit 300, with the product in a vertical state. In the left flip unit 300, when the first flip base 304 is in the initial position, the first guide rod 323 of the first flip cylinder 303 pushes forward, driving the first side push block 308 of the pulley to push forward the bearing of its first connecting part 320 through the first flip floating joint 319, driving the entire module of the sixth linear guide rail 321 to move forward, causing the first product positioning block 306 to move forward. When the first flip cylinder 303 collides the first fixing part 322 fixed on the sixth linear guide rail 321 with the first stop block 307 with spring, the positioning is completed. At this time, the first fixing part 322 moves to a position where it can no longer hold the product, waiting for the product to be placed in. When the product is placed horizontally on the first platform 305 of the left flipping unit 300 via the external clamping device, the first guide rod 323 of the first flipping cylinder 303 retracts to its initial position. The compression spring on the spring-loaded first stop block 307 forces the first fixing part 322 fixed on the sixth linear guide rail 321 to move backward, causing the first product positioning block 306 to move backward until the product is clamped. After the product is fully clamped, the motor rotates 90 degrees clockwise. When the first vertical limit block 311 on its shaft contacts the first vertical positioning pin 309 and reaches the set torque value, the brake engages, keeping the product vertical. At this point, the external clamping device clamps the product, and the first guide rod 323 of the first flipping cylinder 303 pushes forward, pushing the bearing and its second connecting part 324, causing the first product positioning block 306 to move forward, thereby releasing the product. At this time, the external clamping device removes the product, and the cylinder retracts back to its initial position.

[0074] In the right-flipping unit 400, when the second flipping base 404 is in its initial position, the second guide rod 423 of the second flipping cylinder 403 pushes forward, driving the pulley second side push block 408 to push the third bearing 420 forward through the second flipping floating joint 419. This causes the entire module on the seventh linear guide rail 421 to move forward, making the second product positioning block 406 move forward. When the cylinder collides the second fixing part 422 fixed on the seventh linear guide rail 421 with the spring-loaded second stop block 407, the positioning is completed. At this time, the second product positioning block 406 moves to a position where it cannot hold the product, waiting for the product to be placed. When the product is placed horizontally on the second platform 405 of the right-flipping unit by the external clamping device, the second guide rod 423 of the second flipping cylinder 403 retracts to its initial position. The compression spring on the spring-loaded second stop block 407 forces the second fixing part 422 fixed on the seventh linear guide rail 421 to move backward through the spring force, causing the second product positioning block 406 to move backward together until it holds the product. Once the product is fully clamped, the motor rotates 90 degrees clockwise. When the second vertical limit block 411 on its shaft contacts the second vertical positioning pin 409 and reaches the set torque value, the brake engages, keeping the product vertical. At this point, the external clamping device holds the product, and the second guide rod 423 of the second tilting cylinder 403 pushes forward, pushing the bearing and its third connecting part 424, causing the second product positioning block 406 to move forward, thereby releasing the product. The external clamping device then removes the product, and the cylinder retracts to its initial position.
