[0041] As described in the background, how to safely and efficiently shoot the two sides of the product to complete the appearance record is a technical problem to be solved. Therefore, in an embodiment, the feeding personnel places the product to be recorded on the bearing platform with a transparent area and configures cameras for shooting on the upper and lower sides of the bearing platform. After feeding is completed, the feeding personnel triggers the confirmation area on the display screen to control the cameras on the upper and lower sides of the bearing platform to shoot at the same time, thereby realizing safe and efficient shooting and recording of the two sides of the product to be recorded. In this embodiment, manual triggering of the camera shooting is required when each product to be recorded is fed, which increases the complexity of the operation of the feeding personnel.

[0042] In view of this, the present application proposes an appearance recording device, which is provided with a sensing device at an inlet and outlet for allowing an operator to place the product to be recorded, and a first image capturing unit arranged on the upper side of a bearing platform having a light-transmitting region and a second image capturing unit arranged on the lower side thereof. In this way, the sensing of the operator by the sensing device can achieve automatic control or triggering of the image capturing unit to take pictures when the operator finishes the feeding operation, and the image capturing units on the upper and lower sides can achieve simultaneous acquisition of the appearance images of both sides of the product to be recorded without turning over the product to be recorded, thereby achieving safe and efficient appearance recording of the product to be recorded.

[0043] The appearance recording device described in the present application is a device for taking pictures of a product to be recorded to acquire appearance images of the product to be recorded. The product to be recorded can be a product in the field of electronics, machinery, etc. In an example, the product to be recorded is a circuit board, wherein the circuit board is, for example, a circuit board printed or laid with conductive lines, and further, the circuit board further carries electronic components connected to each other by means of the conductive lines. For example, the circuit board is a PCB board, a packaging substrate, a PCB board configured with electronic components, or a packaging substrate configured with electronic components, etc.

[0044] In the following embodiments, the appearance recording device is taken as an example for description, which is a device for taking pictures of a product to be recorded from both sides to acquire appearance images of both sides of the product to be recorded. It should be noted that the upper side (which can also be referred to as the first surface) of the product to be recorded placed on the bearing platform is the upper surface, and conversely, the lower side (which can also be referred to as the second surface) is the lower surface. According to different preset feeding modes, the upper surface and the lower surface can be either the front surface or the back surface of the product to be recorded.

[0045] Please refer to Figure 1 in combination with Figure 2 and Figure 3 , Figure 1 and Figure 2 show the structural schematic diagram of the appearance recording device of the present application in an embodiment under different viewing angles, Figure 3 show the appearance recording device of the present application Figure 1As shown in the structural schematic diagram of the appearance recording device from one perspective after removing part of the shell, the appearance recording device comprises a bearing assembly 1, a first image capturing unit 2, a second image capturing unit 3, and a sensing device. The bearing assembly 1 comprises a support main body 10 and a bearing platform 11 arranged on the support main body 10 for bearing a product to be recorded, and the support main body 10 has an inlet and outlet 100 for allowing a feeding hand to place or take the product to be recorded. The first image capturing unit 2 is arranged on the upper side of the bearing platform 11 and comprises a first camera 20 for shooting a first surface of the product to be recorded to obtain a first appearance image. The second image capturing unit 3 is arranged on the lower side of the bearing platform 11 and comprises a second camera 30 for shooting a second surface of the product to be recorded through a light-transmitting area of the bearing platform 11 to obtain a second appearance image. The sensing device is arranged on the support main body 10 and comprises a sensing assembly 4 arranged at the inlet and outlet 100 for sensing the feeding hand. In order to clearly illustrate the relative positions of the components in the appearance recording device in the embodiments of the present application, the six directions of up, down, front, back, left and right are defined in Figure 1 to Figure 3

[0046] As shown in Figure 1 , the support main body 10 has an inlet and outlet 100 for allowing a feeding hand to place or take the product to be recorded. Specifically, the feeding hand can place the product to be recorded on the bearing platform 11 through the inlet and outlet 100, or take the product to be recorded on the bearing platform 11 out through the inlet and outlet 100. In the embodiment shown in Figure 1 , the inlet is configured in a rectangular shape, and in other embodiments, the inlet can also be configured in a square shape or other regular or irregular shapes, as long as the shape and size of the inlet can meet the feeding requirements of the feeding hand. The feeding hand can include a human hand or a mechanical hand, and the human hand is not limited to only the palm for taking the product to be recorded, but can also include the arm part. Similarly, the mechanical hand can also include a mechanical arm part. The support main body 10 also has an accommodation space inside for configuring components of the appearance recording device, such as the bearing platform, the first image capturing unit, the second image capturing unit, etc.

[0047] In an embodiment, please refer to Figure 1 and in combination with Figure 3 , as shown in the figure, the support main body 10 comprises a main body support 101 and a shell 102 arranged around the main body support 101. In some examples, the main body support 101 is a hollow frame body with a plurality of hollow areas on the surface and an accommodation space inside. One of the hollow areas in the main body support 101 can be used as the inlet and outlet, for example, as shown in​Figure 3 As shown, the hollow region at the middle of the front side of the main support 101 is the inlet and outlet 100. In order to allow the person to place the product to be recorded on the inlet and outlet 100, the area of the inlet and outlet 100 can be configured as Figure 1 As shown, the shell 102 is not configured, or can be configured as a shell allowing opening and closing. The shell 102 can be used to avoid the influence of external environment light on the shooting appearance image inside the support main body 10, and can also be used to protect the components (such as the first bearing platform, the first image capturing unit, the second image capturing unit, etc.) configured inside the support main body 10. In some examples, the light transmittance of the shell 102 does not exceed the upper limit of light transmittance, for example, the upper limit of light transmittance is 10%-20%. In a specific example, the shell can be configured as a light shield plate or a metal plate, etc.

[0048] It should be noted that although the above embodiment is described by taking the support main body as an example including a main support and a shell configured around the main support, it is not limited thereto, and in other embodiments, the support main body can only include a main support, or only include a shell composed of a material with high hardness (such as metal, alloy, etc.), as long as the support main body has an inlet and outlet for allowing the person to place the product to be recorded.

[0049] Please refer to Figure 1 The bearing platform 11 is located on the support main body 10 and is used to bear the product to be recorded. In an embodiment, the bearing platform 11 is located in the accommodation space inside the support main body 10 and the height thereof matches the height of the inlet and outlet 100, specifically, as shown in Figure 3 As shown, the bearing platform 11 is configured in the accommodation space inside the support main body 10 along the left-right direction, and the height of the bearing platform 11 is close to the height of the lower side of the inlet and outlet 100.

[0050] In order to enable the second image capturing unit located at the lower side of the bearing platform to shoot the second surface (i.e. the lower surface) of the product to be recorded on the bearing platform through the bearing platform, the bearing platform includes a light transmission region, so that when the product to be recorded is located in the light transmission region, the second image capturing unit can shoot the second surface (i.e. the lower surface) of the product to be recorded through the light transmission region. In an embodiment, the light transmittance of the light transmission region is not less than a preset light transmittance, for example, the preset light transmittance is 80%. In a specific embodiment, the bearing platform 11 is configured as a glass flat plate, and further, the bearing platform 11 can be, for example, Figure 3The rectangular glass flat plate is shown, and the entire bearing platform 11 is the light-transmitting area. In other embodiments, only the central area of the bearing platform can be configured as the light-transmitting area, and the shape of the bearing platform can be a square or other regular shape or irregular shape.

[0051] In an embodiment, the appearance recording device further comprises an anti-static pad (not shown) disposed on the bearing platform, which is used to avoid electrostatic damage to the product to be recorded. Specifically, the lower surface of the anti-static pad is in contact with the upper surface of the bearing platform, and the upper surface of the anti-static pad is in contact with the second surface of the product to be recorded. In the embodiment in which the product to be recorded is a circuit board, the anti-static pad can avoid electrostatic damage to electronic components in the circuit board. In some specific embodiments, the anti-static pad can be configured as a light-transmitting anti-static pad made of PVC (polyvinyl chloride), PU (polyurethane), PC (polycarbonate), PET (polyethylene terephthalate), rubber, or silicone, and the light transmittance of the anti-static pad is not less than 80%, for example.

[0052] Referring to Figure 3 , the first image capturing unit 2 is disposed on the upper side of the bearing platform 11 and includes a first camera 20 for photographing the first surface of the product to be recorded to obtain a first appearance image. In an embodiment, the first camera 20 includes a photosensitive sensor (such as a CCD or a CMOS), and the first camera 20 converts the reflected light from the first surface of the product to be recorded received by the photosensitive sensor into a first appearance image. The first camera can be a color camera or a black-and-white camera. It should be noted that the number of first cameras can be one, two, or more. Using two or more first cameras can obtain multiple first appearance images from different positions to avoid the problem that the first appearance image cannot accurately reflect the overall appearance of the first surface due to the blind area of photographing. In the following embodiments, the number of first cameras is one.

[0053] In an embodiment, as Figure 3 shown, the first image capturing unit 2 is disposed on the top of the support body 10, and further, the first image capturing unit 2 further includes a first mounting assembly 21 disposed on the top of the support body 10 for mounting the first camera 20. In other embodiments, the first camera can also be suspended at any position between the top of the support body and the bearing platform.

[0054] In one embodiment, the first mounting assembly comprises an adjustable mechanism allowing adjustment of the spatial position of the camera relative to the carrier platform and a mounting portion connected to the adjustable mechanism for mounting the camera. In the following embodiments, for the sake of distinction, the adjustable mechanism and the mounting portion in the first mounting assembly are referred to as the first adjustable mechanism and the first mounting portion, and the adjustable mechanism and the mounting portion in the second mounting assembly are referred to as the second adjustable mechanism and the second mounting portion.

[0055] Referring to Figure 4 and Figure 5 and in combination with Figure 3 , Figure 4 Fig. 1 shows a schematic structural view of the first image capturing unit in one embodiment of the present application in one perspective, Figure 5 Fig. 2 shows a schematic structural view of the first image capturing unit in one embodiment of the present application in another perspective, as Figure 3 to Figure 5As shown, the first adjustable mechanism includes two first supports 2100 arranged opposite to each other in the front-back direction on the top of the support body 10, two second supports 2101 arranged opposite to each other in the left-right direction across the two first supports 2100, and a third support 2102 arranged across the two second supports 2101. Each of the first supports 2100 includes a first slide rod 21000, and the two second supports 2101 are arranged across the two first slide rods 21000 so that the two second supports 2101 can move on the two first slide rods 21000 in the left-right direction. Similarly, each of the second supports 2101 includes a second slide rod 21010, and the third support 2102 is arranged across the two second slide rods 21010 so that the third support 2102 can move on the two second slide rods 21010 in the front-back direction. The third support 2102 is provided with a strip-shaped hole 21020 so that the first mounting portion 211 can move up and down relative to the strip-shaped hole 21020. Thus, the user can adjust the position of the first camera 20 relative to the bearing platform in the left-right direction by adjusting the position of the second support 2101 on the first support 2100, adjust the position of the first camera 20 relative to the bearing platform in the front-back direction by adjusting the position of the third support 2102 on the second support 2101, and adjust the position of the first camera 20 relative to the bearing platform in the up-down direction by adjusting the position of the first mounting portion 211 on the strip-shaped hole 21020. In this way, the first adjustable mechanism can adjust the spatial position of the first camera 20 relative to the bearing platform 11, i.e., the spatial position of the first camera 20 relative to the bearing platform 11 in the up-down, front-back, and left-right directions, so that the user can adjust the spatial position of the first camera for different sizes of products to be recorded to obtain a complete and clear first appearance image of the first surface of the product to be recorded.

[0056] It should be noted that the first adjustable mechanism can also be configured as a manual adjustment mechanism of other structures or as an automatic adjustment mechanism. In the embodiment where the first adjustable mechanism is configured as an automatic adjustment mechanism, the automatic adjustment mechanism can automatically adjust the spatial position of the first camera relative to the bearing platform under the control of the master control device of the appearance recording device. For example, the first adjustable mechanism includes telescopic rods that can automatically extend and retract in three dimensions of up-down, front-back, and left-right, and driving motors that drive the telescopic rods to extend and retract.

[0057] Please refer to Figure 3The second image taking unit 3 is arranged at the lower side of the bearing platform 11, and includes a second camera 30 for taking a second surface of the product to be recorded through the light-transmitting area to obtain a second appearance image.

The second camera can be a color camera or a black-and-white camera. It should be noted that the number of the second camera can be one or two or more. Using two or more second cameras can obtain multiple second appearance images from different positions to avoid the problem that the second appearance image cannot accurately reflect the overall appearance of the second surface due to the blind area of taking.

[0058] In an embodiment, the second image taking unit 3 is arranged at the bottom of the support body 10, and further, as shown in Figure 3 , the second image taking unit 3 further includes a second mounting assembly 31 arranged at the bottom of the support body 10 for mounting the second camera 30.

[0064] In an embodiment, as shown in Figure 1 the sensing device includes a sensing assembly 4 arranged at the inlet and outlet 100 for sensing the loading hand. By sensing the loading hand, the appearance recording apparatus can automatically control or trigger the first and second image capturing units to take photos to obtain the first appearance image and the second appearance image when determining that the loading operation is completed.

[0065] In some embodiments, the sensing device is configured as a light-based sensing device, for example, the sensing device is a photoelectric sensor (e.g., a reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, or a diffuse reflection type photoelectric sensor) or a time-of-flight sensor. The type of sensing device is not limited in the present application, as long as it can sense the loading hand and output a corresponding electrical signal for the appearance recording apparatus to trigger the camera to take photos. In the following embodiments, the sensing device is taken as a photoelectric sensor as an example for illustration.

[0066] In an embodiment, please continue to refer to Figure 1The sensing component 4 includes a light emitter 40 for emitting light and a light receiver 41 for receiving light. In some examples, the light emitter 40 and the light receiver 41 are located on opposite sides of the inlet / outlet 100, for example, as shown below. Figure 1 The light emitter and receiver are arranged on the left and right sides of the inlet / outlet 100, or on the top and bottom sides of the inlet / outlet 100. However, this is not a limitation; the light emitter and receiver can also be located on the same side of the inlet / outlet. In some embodiments, the light emitted by the light emitter 40 can be infrared light, ultraviolet light, or visible light, such as infrared laser, ultraviolet laser, or visible laser.

[0067] Taking the light emitter 40 and the light receiver 41 located on opposite sides of the inlet / outlet 100 as an example, the sensing component will be described in detail. During the feeding process, the light emitter 40 emits light on one side of the feeding port. The feeding hand blocks the light emitted by the light emitter 40, which reduces the intensity of the light received by the light receiver 41 on the other side of the feeding port. In this way, the feeding hand can be sensed.

[0068] In one embodiment, the sensing component 4 further includes a processing output circuit (not shown). After receiving light, the light receiver 41 converts the intensity of the received light into an electrical signal. The processing output circuit performs signal processing (e.g., amplification, filtering, etc.) on the converted electrical signal and then outputs the processed electrical signal. For example, when the loading operator has not passed through the inlet / outlet 100, the light emitted by the light emitter 40 is not blocked, and the electrical signal output by the sensing component 4 is low. When the loading operator passes through the inlet / outlet 100, the light emitted by the light emitter 40 is blocked, and the intensity of the light received by the light receiver 41 decreases, resulting in a high-level electrical signal. When the loading operation is completed and the loading operator has completely left the inlet / outlet 100, the light emitted by the light emitter 40 is not blocked, resulting in a low-level electrical signal. It should be noted that in the embodiment where the electrical signal output is high when the light emitted by the light emitter 40 is not blocked, the electrical signal output is low when the light emitted by the light emitter 40 is blocked.

[0069] In one embodiment, please refer to Figure 6 and Figure 7 , Figure 6 This application is displayed. Figure 1 A magnified view of a portion of the F1 area in the appearance recording device. Figure 7 This application is displayed. Figure 2As shown in the partial enlarged view of the appearance recording device at F2, the light ray emitter 40 includes a plurality of emitting sources 400 for emitting a plurality of light rays, and the light ray receiver 41 includes a plurality of receiving heads 410 corresponding to the number of the emitting sources 400 for receiving the light rays emitted by the corresponding emitting sources. By providing a plurality of emitting sources and receiving heads 410, the coverage area of the light rays can be increased to improve the sensing accuracy. In other embodiments, the light ray emitter can be configured as a linear laser emitter and the light ray receiver can be configured as a linear laser receiver to increase the coverage area of the light rays.

[0070] To further avoid the problem that the light rays emitted by the light ray emitter cannot cover the feeding area, in an embodiment, the size of the light ray area formed by the light rays emitted by the light ray emitter in the direction perpendicular to the light ray emitting direction is similar to the size of the inlet / outlet in the corresponding direction. The "similar" means that the two sizes are the same or differ by no more than a preset size. The preset size can be determined according to actual tests or experience, for example, the preset size is 1-5 cm.

[0071] Taking the case that the light ray emitter and the light ray receiver are located on the left and right sides of the inlet / outlet and the light ray emitter includes a plurality of emitting sources and the light ray receiver includes a plurality of receiving heads as an example, please refer to Figure 8 , which shows a schematic diagram of the light ray area formed by the light rays emitted by the light ray emitter in an embodiment of the present application. As shown in the figure, the light ray emitter 40 emits a plurality of light rays G for the light ray receiver 41 to receive. The plurality of light rays form a light ray area Y in the up-down and left-right directions. The size of the light ray area Y in the direction perpendicular to the light ray emitting direction is H, i.e., the size of the light ray area Y in the up-down direction is H. The size H is similar to the size of the inlet / outlet in the up-down direction. It should be noted that when the light ray emitter and the light ray receiver are located on the top and bottom sides of the inlet / outlet, the size of the light ray area formed by the light rays emitted by the light ray emitter in the left-right direction is similar to the size of the inlet / outlet in the left-right direction.

[0072] In an embodiment, the appearance recording device further comprises a master device 6, which is configured to receive a sensing signal of the sensing device and trigger the first and second image capturing units to take pictures based on the sensing signal. The sensing signal is an electrical signal output by the sensing device. Specifically, the master device 6 determines, based on the electrical signal output by the sensing device, that the feeding operation is completed and triggers the first and second image capturing units to take pictures. For example, when the feeding hand passes through the inlet and outlet, the sensing device outputs a high-level electrical signal. When the feeding hand completely exits the inlet and outlet, the sensing device outputs a low-level electrical signal. At this time, the master device 6 determines, based on the received electrical signal, that the feeding operation is completed and controls the first and second image capturing units to take pictures.

[0073] In an embodiment, the master device 6 is further configured to identify the code of the product to be recorded according to the first appearance image and / or the second appearance image, and store the first and second appearance images in association with the code.

In an embodiment in which the code is located on only the first surface or the second surface of the product to be recorded, the master device 6 can identify the code of the product to be recorded based on the appearance image (e.g., the first appearance image or the second appearance image) of the surface on which the code is located, or identify the code of the product to be recorded based on the appearance images of the two surfaces and store the first and second appearance images in association with the code. In an embodiment in which the code is one and located on both the first surface and the second surface of the product to be recorded, the master device 6 can identify the code of the product to be recorded based on any appearance image or the appearance images of the two surfaces and store the first and second appearance images in association with the code. In an embodiment in which the code is two and located on the first surface and the second surface of the product to be recorded, respectively, the master device 6 can identify the code on the first surface based on the first appearance image and identify the code on the second surface based on the second appearance image, and then store the first appearance image in association with the code on the first surface and store the second appearance image in association with the code on the second surface.
