[0045] In view of the problems mentioned in the background art, the present application proposes a material taking device. The device is equipped with a camera assembly on the material taking head, which can capture the external environment information of the material taking head, so as to accurately determine the pick-and-place position of the integrated circuit (IC), and thus improve the pick-and-place efficiency of the IC. It is worth noting that the material taking device not only applies to the pick-and-place work of IC, but also can be extended to the pick-and-place task of other types of materials.

[0046] The material taking device according to the present application will be described in detail below.

[0047] Figure 1 An external view of the material taking device 100 according to some embodiments. Figure 2 An external view of the material taking device 100 according to some embodiments. Figure 1 A sectional view of the structure shown in FIG. 1.

[0048] According to some embodiments of the present application, please refer to Figure 1 and Figure 2 The material taking device 100 according to the embodiments of the present application comprises a material taking assembly 10, a negative pressure assembly 20 and a camera assembly 30. The material taking assembly 10 comprises a material taking head 11, and the interior of the material taking head 11 is provided with a material suction passage 11a which is in communication with the exterior of the material taking head 11. The negative pressure assembly 20 is in communication with the material suction passage 11a, and is used to provide negative pressure to the material suction passage 11a. The camera assembly 30 is installed on the material taking head 11, and the material suction passage 11a is located on the shooting light path of the camera assembly 30, so that the camera assembly 30 can shoot the external environment of the material taking head 11 through the material suction passage 11a.

[0049] The material suction passage 11a is basically in a tubular structure, one end of which is directly or indirectly connected to the negative pressure assembly 20, and the other end is open to communicate with the exterior of the material taking head 11. When the negative pressure assembly 20 generates negative pressure, the ICs can be sucked into the material suction passage 11a through the open end of the material suction passage 11a, and then the ICs can be transferred by moving the material taking head 11.

[0050] The negative pressure assembly 20 is responsible for providing the required negative pressure to the material suction passage 11a. Figure 3 The composition structure of the material taking device 100 in some embodiments is shown. According to Figure 3 , the negative pressure assembly 20 generally comprises a vacuum generator 21 and a control valve 22. The suction end of the vacuum generator 21 is directly or indirectly in communication with the material suction passage 11a, and the exhaust end thereof is in communication with the outside (for example, the atmosphere) through an exhaust pipeline 23. The control valve 22 is installed on the exhaust pipeline 23, and is used to adjust the opening and closing of the exhaust pipeline 23. When it is required to provide negative pressure to the material suction passage 11a, the vacuum generator 21 is started and the control valve 22 is operated to open the exhaust pipeline 23.

[0051] It should be noted that the shooting light path of the camera assembly 30 refers to the light propagation path that can be captured by the camera assembly 30. The material suction passage 11a is located on the shooting light path of the camera assembly 30, which means that the light captured by the camera assembly 30 must pass through the material suction passage 11a.

[0052] The camera assembly 30 generally comprises a camera 31, which is an optical imaging device capable of capturing images and videos, and its application type is not limited as a conventional equipment. The camera assembly 30 can capture the external environment of the picking head 11 through the suction channel 11a, which means that the light from the external environment of the picking head 11 can propagate through the suction channel 11a and reach the shooting end of the camera 31, so as to be captured by the camera 31 to generate image and video information of the external environment.

[0053] The camera 31 is installed on the picking head 11, which can be placed inside or outside the picking head 11. If the camera 31 is located outside the picking head 11, its shooting end should face the inside of the picking head 11 in order to capture the light propagating from the suction channel 11a.

[0054] In actual application, the picking device 100 described above, after the picking head 11 is sent into the IC storage device, the camera assembly 30 captures the environmental conditions inside the device through the suction channel 11a, which facilitates the observation and determination of the picking and placing position of the IC by the staff. This can overcome the influence of poor visibility inside the device on the picking and placing operation of the IC to some extent, and help to realize the accurate picking and placing of the IC, thereby improving the efficiency of the picking and placing of the IC.

[0055] In some embodiments, the camera 31 has a built-in illumination function, which can provide illumination light to the inside of the device through the suction channel 11a. In this way, the camera assembly 30 can capture clearer images and videos, effectively reducing the influence of poor visibility inside the device on the picking and placing operation of the IC, thereby improving the efficiency of the picking and placing of the IC.

[0056] In some embodiments, referring to Figure 2 , the camera assembly 30 comprises the camera 31 and a light path changing device 32, both of which are installed on the picking head 11. In the above-mentioned shooting light path, the light path changing device 32 is located between the suction channel 11a and the camera 31, which is used to guide the light to propagate from the suction channel 11a to the camera 31.

[0057] The light path changing device 32 is an optical assembly capable of adjusting the propagation path of light, which includes prisms, plane mirrors and other forms. It changes the propagation direction of light through mechanisms such as refraction or reflection. The specific type of the light path changing device 32 is not limited in this paper. The light path changing device 32 can be one or more, the key is to ensure that the light can smoothly propagate from the suction channel 11a to the shooting end of the camera 31.

[0058] The configuration of the light path changing device 32 enhances the layout flexibility of the relative position between the suction channel 11a and the camera 31. This is particularly important for a small material taking head 11, because it can reduce the length of the material taking head 11 in the extension direction F3 of the suction channel 11a, making the overall structure of the material taking head 11 more compact.

[0059] Figure 4 The internal structure of the material taking head 11 of the embodiments described in the foregoing is shown. Figure 2 Figure 5 Figure 6 The appearance views of the material taking head 11 of the embodiments shown in the foregoing at different angles are respectively presented. Figure 4

[0060] In specific embodiments, in combination with Figure 2 Figure 4 The internal structure of the material taking head 11 is provided with a mounting channel 11b and a transition cavity 11c, the transition cavity 11c being communicated between the mounting channel 11b and the suction channel 11a, and the mounting channel 11b and the suction channel 11a being two intersecting straight channels. The camera 31 is mounted in the mounting channel 11b, and the shooting end thereof is arranged towards the transition cavity 11c, and the light path changing device 32 is located in the transition cavity 11c.

[0061] The straight channel refers to a channel extending along a straight line direction. The suction channel 11a as a straight line type channel is more in line with the characteristics of straight line propagation of light, thereby allowing more light outside the material taking head 11 to propagate to the camera 31 through the suction channel 11a, improving the light transmittance of the suction channel 11a, and further improving the imaging quality of the camera 31.

[0062] The mounting channel 11b is designed as a straight channel intersecting with the suction channel 11a, which not only shortens the size of the material taking head 11 in the extension direction F3 of the suction channel 11a, but also simplifies the mounting process of the camera 31. For better understanding, in combination with Figure 4 Figure 5 The end of the mounting channel 11b away from the transition cavity 11c is open, so as to facilitate the insertion and mounting of the camera 31.

[0063] Of course, in other embodiments, the suction channel 11a can also be a curved channel, a broken line channel, etc.

[0064] In specific examples, in combination with Figure 2 The extension direction of the mounting channel 11b is arranged perpendicularly to the extension direction F3 of the suction channel 11a. The light path changing device 32 comprises a right-angle prism, which can change the propagation direction of light by 90 degrees.

[0065] Further to the embodiments, in combination with Figure 2 Figure 6 The extension direction of the mounting channel 11b is arranged perpendicularly to the extension direction F3 of the suction channel 11a. The light path changing device 32 comprises a right-angle prism, which can change the propagation direction of light by 90 degrees.​​​​​It is understood that the end of the transition cavity 11c opposite to the mounting channel 11b is provided as an open end c1 communicating with the outside of the material taking head 11, and the material taking assembly 10 comprises a sealing block 12 encapsulating the open end c1. The sealing block 12 has a first end 12g facing the mounting channel 11b, and the light path changing device 32 is clamped between the first end 12g and the inner wall of the transition cavity 11c.

[0066] In the process of assembling the material taking device 100, the light path changing device 32 can be loaded into the transition cavity 11c through the open end c1 of the transition cavity 11c, and clamped between the first end 12g of the sealing block 12 and the inner wall of the transition cavity 11c through the sealing block 12, so as to complete the installation of the light path changing device 32.

[0067] Specifically, the first end 12g of the transition cavity 11c is formed with a recess, and the second end of the sealing block 12 away from the first end 12g can be provided with a flange, the recess is arranged in the groove, and the recess is fixed to the material taking head 11 through fasteners such as threads.

[0068] The sealing block 12 is usually made of light-proof material to prevent light from propagating to the camera 31 through the sealing block 12 and the light path changing device 32 via a path other than the material suction channel 11a, thereby affecting the imaging quality of the camera 31.

[0069] Figure 7 A structural schematic diagram of the sealing block 12 in an embodiment.

[0070] In some embodiments, the sealing block 12 is combined with the light path changing device 32. Figure 2 and Figure 7 It is understood that the first end 12g of the sealing block 12 is provided with a clamping groove g1 and an avoidance channel g2, and the clamping groove g1 is concave inwardly away from the mounting channel 11b. In the extension direction F3 of the material suction channel 11a, the avoidance channel g2 is arranged opposite to the material suction channel 11a and communicates between the clamping groove g1 and the material suction channel 11a. The light path changing device 32 is clamped in the clamping groove g1.

[0071] The light path changing device 32 can be partially or completely disposed in the clamping groove g1. The shape of the clamping groove g1 and the shape of the light path changing device 32 can be adaptively designed. For example, if the light path changing device 32 is a right-angle prism, the clamping groove g1 can be designed as a triangular groove matching the right-angle prism. Through the arrangement of the clamping groove g1, support can be provided for the light path changing device 32, thereby enhancing the reliability of the installation.

[0072] In view of the fact that the light path changing device 32 is at least partially embedded in the card slot g1, in order to avoid the light being blocked, a special designed avoiding passage g2 is designed on the block 12 to ensure that the light can smoothly propagate from the suction passage 11a to the light path changing device 32 located in the card slot g1. In this way, the camera 31 can receive a wider range of light, thereby capturing higher quality image videos. The avoiding passage g2 can be in the form of an avoiding hole or an avoiding slot, etc., which is usually linear.

[0073] In some embodiments, the inside of the material taking head 11 is provided with a material storage cavity 11d and a transition cavity 11c. The transition cavity 11c is located on the shooting light path and is arranged on the discharge side in the extension direction F3 of the suction passage 11a. The transition cavity 11c communicates the suction passage 11a and the material storage cavity 11d, and the material storage cavity 11d communicates with the negative pressure assembly 20.

[0074] It is easy to understand that when the camera assembly 30 of the material taking device 100 is equipped with the light path changing device 32, the light path changing device 32 can be installed in the transition cavity 11c, and the transition cavity 11c retains all the characteristics in the foregoing embodiments. Similarly, if the camera assembly 30 is not equipped with the light path changing device 32, the transition cavity 11c can be simplified as a transition space connecting only the suction passage 11a and the material storage cavity 11d. Such a design makes the configuration of the transition cavity 11c more flexible, facilitating the layout of the material storage cavity 11d, the suction passage 11a and the camera assembly 30 on the material taking head 11 for the designer.

[0075] The material storage cavity 11d is designed to store the IC material sucked by the suction passage 11a. The material storage cavity 11d communicates with the suction passage 11a through the transition cavity 11c, and it also communicates with the negative pressure assembly 20, ensuring the connectivity between the negative pressure assembly 20 and the suction passage 11a. Under the action of the negative pressure generated by the negative pressure assembly 20, the IC material located outside the material taking head 11 sequentially passes through the suction passage 11a and the transition cavity 11c, and finally enters the material storage cavity 11d and can be stored therein for a period of time.

[0076] In this way, the material taking head 11 has the function of temporarily storing materials, which helps to improve the working efficiency of the material taking head 11.

[0077] In specific embodiments, referring to Figure 2 , Figure 4 to Figure 6 A plurality of air passing holes 11f are arranged in the material taking head 11, the air passing holes 11f penetrate the cavity wall of the material storage cavity 11d and communicate the material storage cavity 11d and the negative pressure assembly 20.

[0078] It can be understood that a communication passage needs to be provided between the storage cavity 11d and the negative pressure assembly 20. In the embodiment, a plurality of air passing holes 11f collectively form the communication passage. The air passing holes 11f are hole-shaped structures with small flow areas, and they are usually arranged in a concentrated manner. The communication passage formed by the air passing holes 11f not only enables the negative pressure assembly 20 to effectively apply negative pressure to the suction passage 11a, but also prevents ICs from being sucked into the pipeline of the negative pressure assembly 20, compared with a single straight passage with a total flow area.

[0079] In some embodiments, referring to Figure 2 , the storage cavity 11d is located on one side of the suction passage 11a in the first direction F1, and the storage cavity 11d has an arc-shaped inner wall d3 arranged around the second direction F2. The material taking head 11 is provided with a plurality of air passing holes 11f, the air passing holes 11f penetrate through the arc-shaped inner wall d3 and are communicated with the negative pressure assembly 20. The first direction F1, the second direction F2 and the extension direction F3 of the suction passage 11a are intersected two by two and are not coplanar.

[0080] The extension direction F3 of the suction passage 11a is usually a straight direction, and the first direction F1, the second direction F2 and the extension direction F3 of the suction passage 11a are approximately perpendicular two by two. The storage cavity 11d is arranged on one side of the suction passage 11a in the first direction F1, which can reasonably utilize the space in the material taking head 11, so that the structure inside the material taking head 11 is more compact.

[0081] The arc-shaped inner wall d3 of the storage cavity 11d is arranged along the second direction F2, and the air passing hole 11f can be located on the side of the arc-shaped inner wall d3 away from the suction passage 11a in the first direction F1. The arc-shaped inner wall d3 can be a circular arc, but is not limited thereto. Notably, the arc-shaped inner wall d3 can be directly connected with the cavity wall of the transition cavity 11c, or connected through a straight inner wall.

[0082] In the IC suction process, the negative pressure guides the ICs to pass through the suction passage 11a, the transition cavity 11c in turn, and slide along the arc-shaped inner wall d3 into the storage cavity 11d. The maximum negative pressure of the storage cavity 11d is located in the inner wall region where the air passing hole 11f is located. By arranging the air passing hole 11f at the arc-shaped inner wall d3, the arc-shaped structure of the arc-shaped inner wall d3 is used for guidance, so that the risk of collision damage of the ICs is reduced during the process of entering the storage cavity 11d, thereby helping to ensure the quality of the ICs.

[0083] In optional embodiments, the material taking head 11 is equipped with an anti-static function, which aims to improve the reliability of the quality of the ICs stored in the storage cavity 11d. The material taking head 11 can be made of an anti-static material (such as metal, carbon fiber, etc.) as a whole, or an anti-static coating can be coated on the surface of the material taking head 11.

[0084] In some embodiments, referring toFigure 4 and Figure 6 , in combination Figure 2 , the storage cavity 11d is provided with a discharge port d1 at one end in the extension direction F3 of the suction channel 11a, and the material taking assembly 10 further comprises a material taking cover 14 for opening and closing the discharge port d1.

[0085] In the conventional operation mode of the material taking device, the suction channel 11a extends from bottom to top. The discharge port d1 is located below the storage cavity 11d, facilitating the discharge of the material. The material taking cover 14 is installed at the discharge port d1, which will be closed to cover the discharge port d1 during the suction process; while during the material taking, the material taking cover 14 will be opened to expose the discharge port.

[0086] The material taking cover 14 can be installed on the material taking head 11 through various ways such as threaded connection, clamping, rotary connection, etc. It is detachable or movably connected to the material taking head 11, as long as it can realize the opening and closing function of the discharge port d1.

The placement seat 42 can also be connected with the fixing plate 41 through bolts and other fasteners. The placement seat 42 can be designed in various forms such as plate or box. Specifically, the placement seat 42 can be designed as a cuboid container, the adjacent two ends of which remain open, so that the material taking head 11 can freely enter and exit the internal space thereof through the open end thereof, and the material taking head 11 can be conveniently stored and placed before and after taking materials.

[0099] The adsorption base 50 is capable of being adsorbed to an external structure (for example, a material storage device or other device) outside the material taking device 100 through the adsorption member 52, so as to realize flexible use of the display assembly 60. The mounting position 51 of the adsorption base 50 can be various structural forms such as a mounting hole, a mounting slot, etc. The display assembly 60 is used for data connection with the camera 31 in the camera assembly 30, so as to display the image and video information captured by the camera 31.

[0100] The endoscope generally consists of a probe, a display control unit, and a data transmission unit (for example, a data line) connecting the probe and the display control unit. The display control unit is responsible for displaying the image and video data captured by the probe, facilitating observation and analysis by the staff. In addition, the display control unit can also contain a control panel, through which the staff can adjust the image parameters (such as brightness, contrast), control the movement of the probe, and start functions such as recording and taking pictures. The display processing unit usually also contains a processor for noise reduction, enhancement, etc. of the image data transmitted by the probe. For the specific working principle and structural composition of the endoscope, reference can be made to existing technical documents, which will not be described in detail here. In actual application, the probe of the existing endoscope can be used as the camera assembly 30, and the display control unit thereof can be used as the display assembly 60, realizing integration of display and control functions.

For detailed description of the vacuum generator 21 and the control valve 22, please refer to the foregoing, which will not be described here.

[0102] In addition, multiple adsorption members 52 can be provided to enhance the stability of adsorption. In actual application, the adsorption base 50 makes the use of the display assembly 60 more flexible. Specifically, the adsorption member 52 can be but is not limited to a magnetic adsorption type member.

[0103] In some embodiments, as shown in Figure 3 , the fixing tool 40 further includes a hook 43 provided on the fixing plate 41, for hanging tools or other objects by the staff, so as to improve work efficiency.

[0104] In some embodiments, as shown in Figure 3 and Figure 8 , the adsorption base 50 consists of two intersecting plate bodies, which are connected in a substantially L shape. The adsorption member 52 is provided on one of the plate bodies, and the mounting position 51 is located on the other plate body. This design not only facilitates adsorption and installation of the adsorption base 50, but also simplifies the installation process of the display assembly 60.
