Detailed Implementation

[0042] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0043] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance. Additionally, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0044] In related technologies, during the initial production process of a U-shaped phone frame, the sheet metal is cut into linear raw materials of corresponding dimensions through multi-wire cutting. These linear raw materials are then bent to obtain the initial U-shaped phone frame. This phone frame is a semi-finished product and requires traceability marking for each product. It also needs dimensional and appearance optical inspection according to the drawings. After inspection, the semi-finished products need to be categorized before shipment. However, current phone frame inspection equipment cannot perform comprehensive inspection of the phone frame. For example, it cannot inspect the markings on the phone frame. This may result in phone frames with inaccurate or unclear markings being shipped as qualified products, affecting the quality and yield rate of the phone frames.

[0045] The mobile phone frame detection device in the exemplary embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0046] refer to Figures 1 to 11 As shown, this disclosure provides a mobile phone frame inspection device, including an inspection table 1, a conveying component 2, a marking component 3, and an image inspection component 4; the conveying component 2 is disposed on the inspection table 1 and is used to place and convey the mobile phone frame; the marking component 3 is disposed on the inspection table 1 and is used to mark the mobile phone frame; the image inspection component 4 is disposed on the inspection table and can be used to inspect the size and / or appearance of the mobile phone frame; wherein, the marking component 3 and the image inspection component 4 are arranged sequentially in the conveying direction of the conveying component 2.

[0047] Through the above technical solution, after the mobile phone frame is transferred to the conveying component 2, the conveying component 2 will carry the mobile phone frame through the marking component 3 and the image detection component 4 in sequence. When the mobile phone frame passes through the marking component 3, the marking component 3 can mark the mobile phone frame by irradiating the mobile phone frame with a laser. For example, the mark can be a QR code, barcode or other mark. Subsequently, the mobile phone frame will pass through the image detection component 4. In addition to detecting the size and / or appearance of the mobile phone frame, the image detection component 4 can also detect the marking position of the marking component 3 on the mobile phone frame and the clarity of the mark after marking. Based on this, the mobile phone frame detection device disclosed herein can perform more comprehensive detection of the mobile phone frame, thereby improving the quality and yield of the mobile phone frame.

[0048] In some embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, the conveying component 2 may include a frustum 21, which is rotatably mounted on the inspection table 1 and includes a limiting structure 22 for restricting the movement of the phone frame on the frustum 21. The inspection table 1 includes multiple processing stations evenly distributed along the outer periphery of the frustum 21. The marking component 3 and the image detection component 4 are sequentially arranged on two adjacent processing stations along the rotation direction of the frustum 21. After the phone frame is limited by the limiting structure 22, it can pass through the marking component 3 and the image detection component 4 sequentially during the rotation of the frustum 21, thereby realizing the inspection of the phone frame. The arrangement of the frustum 21 can reduce the length of the conveying component 2 in the linear direction, that is, to a certain extent, reduce the space occupied by the conveying component 2.

[0049] In addition, such as Figure 1 and Figure 2 As shown, there can be multiple limiting structures 22, which can be arranged at intervals along the rotation direction of the frustum 21. The angle formed between two adjacent processing stations and the center of the frustum 21 is equal to the angle formed between two adjacent limiting structures 22 and the center of the frustum 21. The multiple limiting structures 22 allow for multiple phone frames to be mounted on the frustum 21. Since the angles formed between two adjacent processing stations and the center of the frustum 21 are equal to the angles formed between two adjacent limiting structures 22 and the center of the frustum 21, when a phone frame on a previous limiting structure 22 passes the processing station corresponding to the image detection component 4, the phone frame on a subsequent limiting structure 22 is precisely positioned at the processing station corresponding to the marking component 3. That is, while one phone frame is being detected by the image detection component 4, the marking component 3 is marking another phone frame, thereby improving the detection efficiency of the equipment.

[0050] For example, the inspection station 1 may be provided with four processing stations along the rotation direction of the truncated cone 21, namely a first processing station, a second processing station, a third processing station, and a fourth processing station. The first processing station is used to place the mobile phone frame on the limiting structure 22 of the truncated cone 21. The second processing station is set correspondingly to the marking component 3. The third processing station is set correspondingly to the image detection component 4. The fourth processing station is used to remove the inspected mobile phone frame from the truncated cone 21. At the first and fourth processing stations, the mobile phone frame can be manually placed or removed from the limiting structure on the truncated cone 21. Alternatively, a robotic arm or linear module can be used to automatically place or remove the phone frame from the limiting structure 22 on the rotary table 21. In this way, while the phone frame at the first processing station is placed into the limiting structure 22, the marking component 3 will mark the phone frame at the second processing station, the image detection component 4 will detect the phone frame at the third processing station, and the phone frame at the fourth processing station can be removed from the limiting structure 22. Thus, the inspection equipment can transfer, process and inspect four phone frames at the same time, improving the working efficiency of the inspection equipment.

[0051] In addition, a laser rangefinder 101 can be installed between the first and second processing stations of the inspection station 1. The laser rangefinder 101 can be used to determine whether a mobile phone frame is installed on the limiting structure 22 of the truncated cone 21.

[0052] In some implementations, such as Figure 1 and Figure 2 As shown, the limiting structure 22 may include a first limiting member 221 and a second limiting member 222 spaced apart from the first limiting member 221. The phone frame is located between the first limiting member 221 and the second limiting member 222, and the first limiting member 221 can fit against the wall of the phone frame, while the second limiting member 222 can abut against the other wall of the phone frame. At least one of the first limiting member 221 and the second limiting member 222 is movably disposed on the conveying assembly 2. After the phone frame is positioned between the first limiting member 221 and the second limiting member 222, the first limiting member 221 and the second limiting member 222 can approach each other to clamp the phone frame. The fact that the first limiting member 221 can fit against the wall of the phone frame increases the connection area between the first limiting member 221 and the phone frame, ensuring the stability of the clamped phone frame after the second limiting member 222 abuts against the other wall of the phone frame.

[0053] The first limiting member 221 and / or the second limiting member 222 can approach each other in various ways. For example, the frustum 21 can be provided with a guide rail or guide groove, and the first limiting member 221 and / or the second limiting member 222 can move in the guide rail or guide groove through a cylinder or electric push rod, so as to approach or move away from each other.

[0054] Specifically, such as Figure 1 and Figure 2 As shown, the mobile phone frame can be U-shaped. The first limiting member 221 can include an L-shaped limiting block 2211. The wall of the limiting block 2211 can fit against at least part of the outer wall of the mobile phone frame. The second limiting member 222 includes a circular clamping block 2221. The wall of the clamping block 2221 can abut against the inner wall of the mobile phone frame. The U-shaped mobile phone frame can have two bends. In this way, the L-shaped limiting block 2211 can fit against the outer side of one of the bends, and the circular clamping block 2221 can be located on the inner side of the mobile phone frame and face the bend that fits against the limiting block 2211. This allows the clamping block 2221 to abut against the inner wall of the mobile phone frame near the bend. When the clamping block 2221 is circular, it can abut against the inner wall of the mobile phone frame at two positions simultaneously. This increases the contact area between the second limiting member 222 and the mobile phone frame, ensuring the stability of the mobile phone frame when the truncated cone 21 rotates, thereby improving the accuracy of subsequent marking and image inspection operations on the mobile phone frame.

[0055] The circular clamping block 2221 can be configured as a bearing; in addition, the limiting structure 22 can also include other positioning plates 223 that are parallel to the extension direction of the wall of the U-shaped mobile phone frame, thereby positioning the setting position of the mobile phone frame so that the mobile phone frame can be accurately placed in the corresponding position on the truncated cone 21.

[0056] In embodiments of this disclosure, such as Figure 1 and Figure 3 As shown, the marking assembly 3 may include a marking device 31, a marking table 32, and a protective structure 33. The marking table 32 is disposed on the outer periphery of the conveying assembly 2. Both the marking device 31 and the protective structure 33 are located on the marking table 32. The marking head 311 of the marking device 31 and the protective structure 33 are correspondingly arranged in the height direction, so that the protective structure 33 can surround the laser emitted from the marking head 311. When the marking head 311 of the marking device 31 is performing marking operations, the protective structure 33 can cover at least part of the laser emitted from the marking head 311. In this way, it can prevent the laser from irritating the eyes of the operator to a certain extent, or prevent the operator from coming into contact with the laser due to accidental operation, thereby protecting the operator and improving the safety of the marking assembly.

[0057] Among them, such as Figure 1 and Figure 3 As shown, the marking table 32 may include a marking table body 321 and a support plate 322, with the marking device 31 mounted on the support plate 322. The support plate 322 is vertically and movably mounted on the marking table body 321. Alternatively, the support plate 322 has a slide rail 323 extending in the height direction on the side near the marking head 311, and a protective structure 33 is movably mounted on the slide rail 323. The support plate 322 and the marking table body 321, as well as the protective structure 33 and the slide rail 323, can be movably connected in various ways. For example, a lead screw may be provided inside the marking table body 321, with a connecting block threaded to the screw and a rocker arm at its end. The connecting block is connected to the support plate 322, and the operator can rotate the rocker arm to drive the lead screw to rotate, thereby moving the connecting block on the lead screw to adjust the lifting and lowering of the support plate 322. The slide rail 323 can be in the form of a groove. The protective structure 33 can be provided with fixing holes at the corresponding positions of the slide rail 323. After adjusting the protective structure 33 to the appropriate position of the slide rail 323, the operator can use fasteners such as locking screws that pass through the fixing holes and the slide rail to fix the protective structure 33.

[0058] In some embodiments not shown, the marking assembly 3 can be driven automatically, such as by an electric push rod or a cylinder, to move the carrier plate 322 on the marking table body 321 and the protective structure 33 on the slide rail 323. Alternatively, it can be driven manually, such as by multiple adjustment holes and fasteners, to move the carrier plate 322 on the marking table body 321 and the protective structure 33 on the slide rail 323. Thus, the heights of the marking device 31 and the protective structure 33 can be adaptively adjusted according to the marking situation, allowing the marking assembly 3 to mark different types of parts. This reduces or even eliminates the risk of laser injury to workers while marking parts such as mobile phone frames, improving the safety of the marking assembly.

[0059] Specifically, such as Figure 1 and Figure 3 As shown, the protective structure 33 may include a protective frame 331 with openings on opposite sides in the height direction. The inner wall of the protective frame 331 forms a protective channel 332. The laser emitted by the marking head 311 passes through the protective channel 332 to mark the frame of the mobile phone to be tested. The protective channel 332 can restrict the area where the laser is located. The protective frame 331 may be made of opaque materials such as metal and plastic, or it may be made of materials with poor light transmittance such as dark glass, to block at least part of the light emitted by the laser, thereby reducing or even avoiding laser irritation to the human eye and preventing workers from directly contacting the laser due to accidental operation.

[0060] In some implementations, such as Figure 1 , Figure 4 as well as Figure 5 As shown, the image detection component 4 may include a mounting plate 43 disposed around the conveying component 2 and connected to the detection table 1, and a first image detection unit 41 and a second image detection unit 42 both disposed on the mounting plate 43. The first image detection unit 41 is used to detect the phone frame in the height direction, and the second image detection unit 42 is used to detect the phone frame in the horizontal direction. That is, the image detection component 4 can detect the appearance and / or size of the phone frame from multiple angles. Therefore, the phone frame can be detected from multiple directions, increasing the detection area of ​​the image detection component 4 on the same phone frame, reducing the existence of blind spots, and thus reducing or even avoiding the occurrence of defective products.

[0061] Among them, such as Figure 1 and Figure 4 As shown, the first image detection unit 41 may include a first mounting frame 411, a first adjustment plate 412, a first light source 413, and a first camera 414. The first mounting frame 411 has a rectangular frame structure and its bottom is connected to the mounting plate 43, so that the first mounting frame 411 surrounds the second image detection unit 42. The first adjustment plate 412 is connected to the first mounting frame 411 and extends toward the side of the transmission assembly 2. The first light source 413 is connected to the first adjustment plate 412. The first camera 414 is connected to the first mounting frame 411 and the first camera 414 can pass through the first light source 413 in the height direction to capture the mobile phone frame. Since the first mounting bracket 411 has a rectangular frame structure and its bottom can be connected to the mounting plate 43, the inner wall of the first mounting bracket 411 can be enclosed to form a space for mounting the second image detection unit 42. That is, the first camera 414 and the first light source 413 of the first image detection unit 41 can be arranged adjacent to the second image detection unit 42 in the height direction to realize the detection of the appearance and / or shape of the mobile phone frame from multiple angles, such as in the height direction and the horizontal direction.

[0062] Specifically, such as Figure 1 and Figure 4 As shown, the first mounting bracket 411 can be movably disposed on the mounting plate 43. For example, both the bottom of the first mounting bracket 411 and the mounting plate 43 can be provided with a plurality of connection holes 44. The connection holes 44 at the bottom of the first mounting bracket 411 can correspond to some of the connection holes 44 on the mounting plate 43, and can be connected together by fasteners such as bolts or screws passing through the connection holes 44 on both. Thus, the connection holes 44 at the bottom of the first mounting bracket 411 can be corresponding to different connection holes 44 on the mounting plate 43 to change their position on the mounting plate 43, thereby changing the detection position of the first image detection unit 41.

[0063] In addition, an adjusting screw 45 may be provided on the side of the first mounting bracket 411, and the operator can adjust the position of the first mounting bracket 411 on the side of the mounting plate 43 by turning the adjusting screw 45.

[0064] Furthermore, the first adjusting plate 412 can be movably disposed on the first mounting bracket 411 in the height direction. For example, both the first adjusting plate 412 and the first mounting bracket 411 can be provided with a plurality of through holes 46. The through holes 46 on the first mounting bracket 411 can correspond to different through holes 46 on the first adjusting plate 412. Thus, by changing the position of the first adjusting plate 412 on the first mounting bracket 411, the height of the first adjusting plate 412 can be adjusted.

[0065] Furthermore, the first camera 414 is movably mounted on the first mounting bracket 411 in the height direction. For example, the first camera 414 can be mounted on a manual precision slide 418, which allows for fine-tuning of the height of the first camera 414. The manual precision slide 418 can also be connected to a first connecting plate 415, which can be slidably connected to a second connecting plate 417 connected to a first adjusting plate 412, thereby enabling coarse-tuning of the height of the first camera 414. In this way, the first camera 414 can adjust its height according to the detection environment and requirements, and capture images of the phone's frame.

[0066] Of course, the above adjustment method can also be configured to be adjusted by conventional methods such as electric push rods or cylinders, which will not be described in detail here.

[0067] In some implementations, such as Figure 1 and Figure 4 As shown, a positioning block 416 can be provided on the side of the first adjusting plate 412. Multiple positioning blocks 416 are arranged at intervals along the periphery of the first adjusting plate 412. The first light source 413 is connected to the side of the first adjusting plate 412 facing the detection stage 1 through the positioning block 416. For example, multiple positioning blocks 416 can be provided. Multiple positioning blocks 416 can be arranged at intervals along the periphery of the first adjusting plate 412, and the first light source 413 is fixed to the first adjusting plate 412. This not only ensures the stability of the first light source 413 after being connected to the first adjusting plate 412, but also allows the first light source 413 to be set horizontally, so as to reduce or even avoid the situation where the first light source 413 tilts, resulting in uneven lighting effect and affecting the image detection results.

[0068] In embodiments of this disclosure, such as Figure 1 and Figure 5As shown, the second image detection unit 42 may include a second mounting bracket 421, a second light source 422, and a second camera 423. The second mounting bracket 421 is connected to the mounting plate 43. The second light source 422 and / or the second camera 423 can be movably connected to the second mounting bracket 421 in the direction toward the conveying assembly 2. After the second mounting bracket 421 is connected to the mounting plate 43, there will be a certain gap between it and the mounting plate 43. This gap can be used for the bottom of the first mounting bracket 411 to pass through so that the bottom of the first mounting bracket 411 can be connected to the mounting plate 43. The second mounting bracket 421 may be provided with a slide groove 424 extending in the direction toward the conveying assembly 2. The second light source 422 and / or the second camera 423 can slide on the slide groove 424. Thus, the operator can adjust the distance of the second camera 423 and / or the second light source 422 in the horizontal direction relative to the mobile phone frame, thereby adapting to the detection of different types of mobile phone frames and detection environments, and providing applicability of the image detection unit.

[0069] Among them, such as Figure 1 and Figure 5 As shown, the second camera 423 can be slidably connected to the second mounting bracket 421 via a camera bracket 425. The camera bracket 425 may include a support plate 4251, which has a support hole for the second camera 423 to pass through, and the inner wall of the support hole abuts against the second camera 423. That is, the second camera 423 can slide on the groove 424 on the second mounting bracket 421 via the camera bracket 425 to change its distance from the phone frame. In addition, the support plate 4251 can also provide effective support for the lens of the second camera 423, improving the stability of the second camera during use and increasing the detection efficiency.

[0070] In addition, a clearance hole 47 can be provided in the central area of ​​the first light source 413 and the second light source 422. A camera corresponding to the light source can pass through the clearance hole 47 to take pictures of the mobile phone frame, thereby detecting the mobile phone frame from the height direction and the horizontal direction respectively.

[0071] In embodiments of this disclosure, such as Figure 1 and Figure 6 As shown, the mobile phone frame inspection equipment also includes a loading unit, an unloading component 7, and a transfer component 8. The transfer component 8 can transport the mobile phone frames from the loading unit to the conveying component 2 and can also transport the mobile phone frames from the conveying component 2 to the unloading component 7. Under the action of the transfer component 8, the mobile phone frames can be transferred from the loading unit to the conveying component 2. During the transfer process in the conveying component 2, the mobile phone frames can be marked by the marking component 3 and inspected by the image detection component 4. Finally, the unloading component 7 transfers the mobile phone frames to the corresponding unloading position. Thus, the automation level of the mobile phone frame inspection equipment can be improved to a certain extent, and the inspection efficiency can be increased.

[0072] It should be noted that the transfer component 8 of this disclosure can be configured as any structure capable of transferring the phone frame from one position to another. Since the transfer component 8 is a common structure in manufacturing processes and is a technical means well-known to those skilled in the art, this disclosure provides a simple example of the specific configuration of the transfer component 8. For example, the transfer component 8 may include a robotic arm and a robotic hand mounted on the robotic arm for gripping the phone frame; or, as... Figure 9 As shown, the transfer component 8 may include a linear module 81 with a clamping component 82. For example, the linear module 81 may include a transfer bracket, a cable chain, a lateral cylinder, and a longitudinal cylinder. The clamping component 82 is connected to the cable chain and may include structures such as clamping cylinders and clamping plates. When transferring the phone frame, the lateral cylinder can drive the cable chain to move laterally, thereby placing the clamping component 82 in the corresponding working position, i.e., the position for gripping or placing the phone frame. At this time, the longitudinal cylinder can drive the clamping component 82 to move downward, and the clamping cylinder drives two oppositely arranged clamping plates to move closer or further apart to grip or place the phone frame.

[0073] In addition, to reduce wear on the cable chain during operation, a slide can be installed on the transfer bracket; and the structure of the clamping plate can be adapted to the structure of the mobile phone frame, which is not limited in this disclosure.

[0074] Furthermore, the structure of the transfer component 8 can be adaptively adjusted depending on its location, as long as it can effectively transfer the phone frame.

[0075] In some implementations, such as Figure 1 and Figure 6 As shown, the loading unit includes a loading component 5 and a flipping component 6. The loading component 5 is used to load the phone frame to be tested, and the flipping component 6 is used to flip the phone frame to be tested so that it can be stably placed on the conveying component 2. Transfer components 8 are provided between the loading component 5 and the flipping component 6, between the flipping component 6 and the conveying component 2, and between the conveying component 2 and the unloading component 7. After the operator places the phone frame on the loading component 5, the phone frame on the loading component 5 is transferred to the flipping component 6 by the transfer component 8. The flipping component 6 can adjust the placement state of the phone frame so that it can be placed on the conveying component 2 later. After testing, it is then transferred to the unloading component 7 by the transfer component 8.

[0076] Specifically, such as Figure 1 and Figure 6As shown, the loading component 5 may include a tray 51 and a tray carrier 52. The tray carrier 52 is disposed on the inspection table 1. The tray 51 and the tray carrier 52 are slidably connected so that the tray 51 can reciprocate between a first position and a second position. The first position is used to load the mobile phone frame to be tested onto the tray 51, and the second position is used for the transfer component 8 to transfer the mobile phone frame to be tested from the tray 51 to the flipping component 6. Exemplarily, the first position can be closer to the outside of the mobile phone frame inspection device than the second position. In this way, the tray 51 located at the first position can be convenient for the operator to place the mobile phone frame, and then the tray 51 can be moved to the second position so that the transfer component 8 can transfer the mobile phone frame from the tray 51.

[0077] The material tray 51 can move between the first and second positions in various ways. For example, the material tray carrier 52 can be equipped with a slide rail 54, and the material tray 51 can be slidably connected to the slide rail 54 via a connecting plate 55. The connecting plate 55 can be equipped with a positioning structure 56, which can restrict the movement of the material tray 51 on the connecting plate 55 after the material tray 51 is placed on the connecting plate 55. The operator can manually push and pull the material tray 51 to move it between the first and second positions. Of course, the material tray carrier 52 can also be equipped with components such as a cylinder or an electric push rod, which can drive the connecting plate 55 to move within the slide rail 54, thereby driving the material tray 51 to move. Thus, the material tray 51 can be moved in an automated manner, improving the feeding efficiency.

[0078] In addition, such as Figure 1 and Figure 6 As shown, a limiting plate 53 may be provided on the side of the tray carrier 52 in the sliding direction of the tray 51. The limiting plate 53 is used to abut against the mobile phone frame when the tray 51 moves to the second position. After the limiting plate 53 abuts against the mobile phone frame on the tray 51 in the second position, it can ensure the consistency of these mobile phone frames, thereby facilitating the subsequent transfer of the component 8.

[0079] The limiting plate 53 can be driven by a cylinder to move in the direction toward the material tray 51, so that after the material tray 51 is in the second position, the state of the mobile phone frame in the second position remains consistent, which facilitates the subsequent transfer component 8 to transfer the mobile phone frame.

[0080] In addition, such as Figure 1 and Figure 6As shown, the tray 51 can be provided with two carrier rods 511 arranged opposite to each other in the moving direction of the tray 51 for placing mobile phone frames. The carrier rods 511 are provided with a plurality of spaced limiting grooves 512. The limiting grooves 512 can be used to hang mobile phone frames. For example, the limiting grooves 512 on the two carrier rods 511 can be arranged one-to-one. In this way, the limiting groove 512 on one carrier rod 511 can form a limiting groove group with the limiting groove 512 on the other carrier rod 511 to hang a mobile phone frame together. That is, the opening of the U-shaped mobile phone frame can be placed downward so that the inner sidewall of the mobile phone frame is hung on the tray 51 through the limiting groove group. This can reduce the space occupied by a single mobile phone frame in the lateral direction of the tray 51 while ensuring the stability of the tray 51 loading. Therefore, the number of mobile phone frames that can be loaded in a unit tray 51 can be increased, thereby improving the loading efficiency.

[0081] It should be noted that the size of the upper limit groove 512 of the material carrier 511 and the spacing between the limit groove 512 can be adjusted adaptively so that the material tray 51 can load different models of mobile phone frames, thereby improving the applicability of the feeding component 5.

[0082] In addition, to further improve the feeding efficiency, multiple feeding components 5 can be provided, and multiple feeding components 5 can be arranged side by side along the conveying direction of the conveying component 8 between the feeding component 5 and the flipping component 6.

[0083] In addition, the feeding assembly 5 can also be equipped with a sensor for detecting whether the material tray is full.

[0084] In embodiments of this disclosure, such as Figure 1 and Figure 7 As shown, the flipping component 6 can be disposed between the feeding component 5 and the conveying component 2, and is used to flip the phone frame removed from the feeding component 5 so that the phone frame can be placed on the limiting structure 22 on the conveying component 2. Since the U-shaped phone frame on the feeding component 5 is hung on the feeding component 5 with its opening facing downwards, in order to place it stably on the conveying component 2, the flipping component 6 can rotate the phone frame by 90°, that is, the phone frame can be placed horizontally on the conveying component 2. This increases the contact area between the phone frame and the conveying component 2, and improves the stability of the phone frame after the transfer component 8 places it on the conveying component 2.

[0085] Specifically, such as Figure 1 and Figure 7As shown, the flipping component 6 may include a flipping table 61 and a flipping support 62. The flipping table 61 is disposed on the detection table 1, and the flipping support 62 is flipped and disposed on the flipping table 61. A limiting area 63 is provided on the flipping support 62, and the limiting area 63 is used to clamp at least part of the mobile phone frame. A flipping cylinder 64 can be installed on the flipping table 61. After the output end of the flipping cylinder 64 is connected to the flipping support 62, it can drive the flipping support 62 to rotate, thereby adjusting the position of the mobile phone frame. The limiting area 63 can include two clamping block groups 65. Each clamping block group 65 can include two clamping blocks arranged opposite each other. At least one of the two clamping blocks is connected to a micro cylinder 66 to move closer to or away from the other, thereby clamping the mobile phone frame. In this way, after the transfer component 8 removes the mobile phone frame from the loading component 5, the two sides of the U-shaped mobile phone frame will be inserted between the two clamping blocks of the clamping block group 65 respectively. Then, the micro cylinder 66 will drive at least one clamping block in the clamping block group 65 to move closer to the other clamping block to clamp the sides of the mobile phone frame. At this time, the flipping cylinder 64 will drive the flipping support 62 to rotate, so that the mobile phone frame is placed horizontally, thereby increasing the contact area between the subsequent transfer component 8 and the transfer component 2 after the mobile phone frame is transferred to the transfer component 2, and improving the stability of the mobile phone frame after it moves to the transfer component 2.

[0086] In some implementations, such as Figure 1 and Figure 8 As shown, the feeding assembly 7 may include a conveyor 71, a feeding plate 72 and a pushing mechanism 73. Multiple feeding plates 72 are spaced apart on the side of the conveyor 71, and multiple pushing mechanisms 73 are arranged in a one-to-one correspondence with multiple feeding plates 72. The inspected mobile phone frame can be transferred to the conveyor 71 by the transfer component 8 and moved along the conveyor 71 in the conveying direction. Depending on the inspection result, the mobile phone frame will be conveyed to different areas. For example, if the mobile phone frame is inspected as a qualified product, the conveyor 71, such as a conveyor belt, will continue to convey the mobile phone frame to the designated position. If the mobile phone frame is inspected as a defective product, depending on the reason for the defect, the pushing mechanism 73 can push the defective mobile phone frame to different unloading plates 72 during the conveyor 71. For example, among the multiple unloading plates 72, there may be a first unloading plate for removing defective products, a second unloading plate for removing defective products, and a third unloading plate for removing defective products marked as defective. When the mobile phone frame moves to its corresponding unloading plate 72 by the conveyor 71, the pushing mechanism 73, such as a cylinder, can push the mobile phone frame to its corresponding unloading plate 72 and slide it from the unloading plate to the designated position.

[0087] Among them, the pushing mechanism 73, for example, can be equipped with hydraulic buffers at both ends of the cylinder to buffer the end of the stroke and ensure stability when pushing the mobile phone frame.

[0088] Of course, such as Figure 10 and Figure 11 As shown, in order to protect the above-mentioned components and prevent workers from accidentally contacting them, the mobile phone frame inspection equipment may also have a housing 9. The housing 9 is connected to the inspection table 1 to cover at least part of the components located on the inspection table 1. For example, the material tray 51, the unloading plate 72, and the end of the conveyor 71 located in the first position may be located outside the housing 9 to facilitate loading and unloading operations.

[0089] The housing 9 can be equipped with a buzzer alarm light on the top and an emergency stop switch on the side to stop the operation of the equipment in case of an emergency. In addition, the housing 9 can also be equipped with a display and control device on the side to display the internal working status of the testing equipment and control the testing equipment. The bottom of the testing table 1 can be equipped with casters and a cooling fan on the side to cool down the electrical control components located inside the testing table 1 and ensure the normal operation of the mobile phone frame testing equipment.

[0090] In summary, this disclosure exemplarily illustrates the detection process of a mobile phone frame detection device.

[0091] The operator can first hang the U-shaped mobile phone frame on the material carrier rod 511 of the material tray 51, and then place the full material tray 51 on the connecting plate 55 of the material tray carrier 52. At this time, the material tray 51 is in the first position. Then, the material tray 51 can be moved from the first position to the second position under the action of the cylinder. After the material tray 51 is in the second position, the limiting plate 53 will move towards the material tray 51 so that the mobile phone frame on the material tray 51 is in the same state. In this way, it is convenient for the transfer component 8 to transfer the mobile phone frame to the flipping component 6.

[0092] After the phone frame is transferred to the flipping assembly 6, the two sides of the U-shaped phone frame will be inserted into the gap of the clamping block group 65. At this time, the micro cylinder 66 will drive the two clamping blocks of the clamping block group 65 to move closer to each other to clamp the phone frame. After ensuring the stability of the phone frame during the rotation of the flipping support 62 by the flipping cylinder 64, when the phone frame is rotated to a horizontal position, the transfer assembly 8 located between the feeding unit and the transfer assembly 2 will move the phone frame on the flipping support 62 to the limiting structure 22 of the round table 21.

[0093] The phone frame on the truncated cone 21 will be located between the first limiting member 221 and the second limiting member 222. The second limiting member 222 can move toward the phone frame so that the first limiting member 221 fits against the outer wall of the phone frame and the second limiting member 222 abuts against the phone frame. This ensures the stability of the phone frame when the truncated cone 21 rotates.

[0094] During the rotation of the circular platform 21, the phone frame first passes through the marking component 3, which performs marking operations on the phone frame. After marking, the phone frame passes through the image detection component 4. The first image detection unit 41 and the second image detection unit 42 of the image detection component 4 respectively detect the size and / or appearance of the phone frame, the position of the marking, and the clarity of the marking from the height and horizontal directions. As a result, the phone frame can be inspected more comprehensively, improving the quality and yield of the phone frame.

[0095] After inspection, the mobile phone frame is transferred to the conveyor 71 by the transfer component 8 located between the conveying component 2 and the unloading component 7. If the mobile phone frame is qualified after inspection, the conveyor 71 will send the mobile phone frame to the corresponding unloading position. If the mobile phone frame is unqualified after inspection, according to the reason for the unqualification, the pushing mechanism 73 will push the mobile phone frame to the corresponding unloading plate 72 during the process of conveying the mobile phone frame by the conveyor 71. In this way, the inspection of the mobile phone frame is completed.
