[0002] In recent years, with the rapid development of information technology, display terminals such as tablet computers, laptops, and mobile phones have become indispensable tools in our lives. In the design and production of display terminals such as tablet computers, laptops, and mobile phones, it is inevitable to use components. Currently, most of these components are attached to the circuit board manually.

[0003] However, when the components are attached manually, uneven force is applied to the components, resulting in indentations on the circuitry and affecting the conductivity of the components. Utility Model Content

[0004] The purpose of this application is to provide an attachment fixture and attachment device, which aims to solve the technical problem of uneven force on the device during the attachment process in the prior art.

[0005] To achieve the above objectives, according to one aspect of this application, a mounting fixture is provided for attaching a device to a PCB board. The mounting fixture includes a main body base plate and a fixture part, wherein the fixture part includes a fixture assembly and a support assembly. The fixture assembly is movably mounted on the main body base plate. A first side of the fixture assembly is used to load the PCB board and fix and limit its position. The fixture assembly is provided with a positioning hole, which connects the first side and the second side of the fixture assembly and corresponds to the position of the PCB board loaded on the fixture assembly. The support assembly is mounted on the main body base plate and extends at least partially through the positioning hole from the second side of the fixture assembly to form a positioning groove on the first side of the fixture assembly together with the positioning hole. The positioning groove is used to place the device and to abut and limit the device during the process of attaching the device to the PCB board. The fixture assembly can be driven by an external driving device to drive the PCB board to fit with the device placed in the positioning groove.

[0006] Optionally, the fixture assembly has a first state in which the PCB board mounted on the first side of the fixture assembly avoids the device placed in the positioning slot, and a second state in which the PCB board mounted on the first side of the fixture assembly fits against the device placed in the positioning slot. The fixture assembly can move towards the support assembly under the drive of an external drive device to switch from the first state to the second state.

[0007] Optionally, the fixture assembly includes a fixture base plate, the first side of which forms the first side of the fixture assembly. A vacuum adsorption part is provided on the fixture base plate, which can be connected to an external vacuum generating device and generate a low-pressure area on the first side of the fixture base plate so that the PCB board can be adsorbed and fixed on the first side of the fixture base plate.

[0008] Optionally, a limiting recess is provided on the first side of the fixture base plate. The limiting recess is used to cooperate with the PCB board to limit the sliding of the PCB board relative to the fixture base plate.

[0009] Optionally, the vacuum adsorption section includes a vacuum adsorption hole, the first end of which is connected to the first side of the fixture base plate, and the second end of which is connected to an external vacuum device.

[0010] Optionally, the fixture assembly is provided with a guide hole, and the attachment fixture also includes a guide support part, which includes a guide rod assembly. The guide rod assembly is mounted on the main body base plate and slides in cooperation with the guide hole to guide the movement of the fixture assembly.

[0011] Optionally, the guide support also includes an elastic reset component, which is mounted on the main body base plate and is used to apply elastic force to the jig assembly so that the jig assembly can maintain a first state when no external force is applied.

[0012] Optionally, the positioning slot is used to place multiple devices, which are arranged sequentially along the length of the positioning hole. The fixture assembly can be driven by an external drive device to make the PCB board fit with the device closest to the PCB board among the multiple devices.

[0013] Optionally, the attachment fixture may also include an optical fiber sensor, which is disposed at the bottom of the positioning groove and is used to sense whether a device is present in the positioning groove.

[0014] According to another aspect of this application, an attachment device is provided, the attachment device including an attachment fixture, the attachment fixture being the attachment fixture described above.

[0015] The beneficial effects of the attachment fixture provided in this application are as follows: Compared with the prior art, the attachment fixture provided in this application has a positioning hole on the fixture assembly that connects the first side and the second side of the fixture assembly, and the support assembly passes through at least partially into the positioning hole from the second side of the fixture assembly. This allows the attachment fixture to form a positioning groove for placing the device on the first side of the fixture assembly through the end of the support assembly near the fixture assembly and the inner wall of the positioning hole. When the device is placed in the positioning groove, the end of the support assembly near the fixture assembly can support the device. The sidewalls can limit the position of the device, thereby ensuring that the device has high positional accuracy relative to the fixture assembly. When the external drive device drives the fixture assembly, the device in the positioning slot is supported by the support assembly, so the device will not move with the movement of the fixture assembly. The PCB board mounted on the first side of the fixture assembly will attach to the device as the fixture assembly moves. Since the positioning slot abuts and limits the device during the attachment process, it can ensure that the device is subjected to a more uniform force, thereby improving the attachment accuracy and reliability of the device.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] As described in the background section, in recent years, with the rapid development of information technology, display terminals such as tablets, laptops, and mobile phones have become indispensable tools in our lives. In the design and production of these display terminals, components are inevitably used, and currently, most of these components are manually attached to the circuit board. However, this manual attachment method results in uneven force on the components, causing indentations on the circuitry and affecting their conductivity.

[0030] See Figures 1 to 4 As shown, to solve the above problems, according to one aspect of this application, an embodiment of this application provides a mounting fixture for attaching devices to a PCB board. The mounting fixture includes a main body base plate 10 and a fixture part 20, wherein the fixture part 20 includes a fixture assembly 21 and a support assembly 22. The fixture assembly 21 is movably mounted on the main body base plate 10. A first side of the fixture assembly 21 is used to load the PCB board and fix and limit its position. A positioning hole 2113 is provided on the fixture assembly 21, and the positioning hole 2113 communicates with the fixture assembly 2113. The first and second sides of the fixture assembly 21 correspond to the positions of the PCB board mounted on the fixture assembly 21. The support assembly 22 is mounted on the main body base plate 10 and extends at least partially from the second side of the fixture assembly 21 into the positioning hole 2113, so that the positioning hole 2113 and the positioning hole 2113 form a positioning groove 23 on the first side of the fixture assembly 21. The positioning groove 23 is used to place the device and to abut and limit the device during the process of attaching the device to the PCB board. The fixture assembly 21 can drive the PCB board to fit with the device placed in the positioning groove 23 under the drive of an external drive device. The attachment fixture provided in this embodiment has a positioning hole 2113 on the fixture assembly 21 connecting the first and second sides of the fixture assembly 21. The support assembly 22 passes at least partially through the positioning hole 2113 from the second side of the fixture assembly 21. This allows the attachment fixture to form a positioning groove 23 on the first side of the fixture assembly 21 through the end of the support assembly 22 near the fixture assembly 21 and the inner wall of the positioning hole 2113. When the device is placed in the positioning groove 23, the end of the support assembly 22 near the fixture assembly 21 can support the device. The inner wall of the positioning hole 2113... The device can be positioned to ensure high positional accuracy of the device relative to the fixture assembly 21. When the external drive device drives the fixture assembly 21, the device in the positioning groove 23 is supported by the support assembly 22, so the device will not move with the movement of the fixture assembly 21. The PCB board mounted on the first side of the fixture assembly 21 will attach to the device as the fixture assembly 21 moves. Since the positioning groove 23 abuts and limits the device during the attachment process, it can ensure that the device is subjected to a more uniform force, thereby improving the attachment accuracy and reliability of the device.

[0031] In one specific embodiment, the inner wall of the positioning hole 2113 provided in this embodiment forms the side wall of the positioning groove 23, and the end of the support component 22 near the fixture component 21 forms the bottom wall of the positioning groove 23. A more uniform force can be applied to the device through the bottom wall of the positioning groove 23.

[0032] In an optional embodiment, the support assembly 22 provided in this embodiment includes a support screw, and a threaded hole is provided on the main body base plate 10. The first end of the support screw is screwed into the threaded hole so that the support screw is installed on the main body base plate 10. The second end of the support screw is at least partially inserted into the positioning hole 2113. Tightening the support screw can change the distance from the second end of the support screw to the first side of the fixture assembly 21, thereby changing the size of the positioning groove 23.

[0033] In an optional embodiment, the positioning holes 2113 and support components 22 provided in this embodiment are multiple. The multiple positioning holes 2113 are spaced apart on the fixture component 21, and the multiple support components 22 correspond one-to-one with the multiple positioning holes 2113. By setting multiple positioning holes 2113 and support components 22, and making the multiple support components 22 correspond one-to-one with the multiple positioning holes 2113, multiple positioning grooves 23 can be formed at different positions on the first side of the fixture component 21. This allows the mounting fixture to mount multiple devices on a PCB board at the same time, effectively improving the production efficiency of the mounting fixture provided in this embodiment.

[0034] In one specific embodiment, the fixture assembly 21 has a first state in which the PCB board mounted on the first side of the fixture assembly 21 avoids the device placed in the positioning groove 23, and a second state in which the PCB board mounted on the first side of the fixture assembly 21 is in contact with the device placed in the positioning groove 23. The fixture assembly 21 can move towards the support assembly 22 under the drive of an external driving device to switch from the first state to the second state. When the external driving device drives the fixture assembly 21 to move towards the support assembly 22, the device in the positioning groove 23 is supported by the support assembly 22, so the device will not move with the fixture assembly 21. However, the PCB board mounted on the first side of the fixture assembly 21 will gradually move closer to the device as the fixture assembly 21 moves, thereby achieving the attachment between the PCB board and the device.

[0035] In another embodiment, the fixture component 21 provided in this embodiment can also be switched from the first state to the second state manually.

[0036] See Figures 2 to 4As shown, in a specific embodiment, the fixture assembly 21 includes a fixture base plate 211. A first side of the fixture base plate 211 forms the first side of the fixture assembly 21. A vacuum adsorption section 2111 is provided on the fixture base plate 211. The vacuum adsorption section 2111 can communicate with an external vacuum generator and generates a low-pressure area on the first side of the fixture base plate 211, allowing the PCB board to be adsorbed and fixed to the first side of the fixture base plate 211. By providing the vacuum adsorption section 2111 on the fixture base plate 211, which can communicate with an external vacuum generator, the mounting fixture can adsorb the PCB board onto the first side of the fixture base plate 211 through the vacuum adsorption section 2111. This adsorption and fixation of the PCB board by the vacuum adsorption section 2111 prevents displacement of the PCB board during device mounting, improving the mounting quality. Furthermore, the vacuum adsorption section 2111 allows for rapid fixation of the PCB board, enabling operators or automated equipment to perform subsequent mounting actions more quickly, thus improving production efficiency.

[0037] In one optional embodiment, the positioning hole 2113 provided in this embodiment is disposed on the positioning base plate.

[0038] See Figure 2 and Figure 3 As shown, in a specific embodiment, a limiting recess 2112 is provided on the first side of the fixture base plate 211. The limiting recess 2112 is used to cooperate with the PCB board to restrict the sliding of the PCB board relative to the fixture base plate 211. Providing the limiting recess 2112 on the first side of the fixture base plate 211 provides a precise placement position for the PCB board and ensures the correct loading angle of the PCB board, avoiding assembly errors caused by angle deviations. Simultaneously, the cooperation between the limiting recess 2112 and the PCB board restricts the sliding of the PCB board relative to the fixture base plate 211, ensuring the attachment quality of the components. Furthermore, since the limiting recess 2112 can quickly position the PCB board to the correct position, operators or automated equipment can start subsequent operations more quickly. In mass production of PCB board-related products, each PCB board can be in the same position and state under the action of the limiting recess 2112, making the production process of each product highly consistent and helping to ensure the stability of product quality.

[0039] In an optional embodiment, the fixture assembly 21 provided in this embodiment further includes a fixture cover plate 212, which covers the limiting recess 2112 to prevent external driving devices from directly contacting the PCB board mounted on the first side of the fixture base plate 211, thereby improving the reliability of the fixture attachment.

[0040] In an optional embodiment, a handle 2121 is provided on the side of the fixture cover plate 212 away from the fixture base plate 211. By providing a handle 2121 on the side of the fixture cover plate 212 away from the fixture base plate 211, it is convenient to disassemble and assemble the fixture cover plate 212, which is beneficial to improving the efficiency of manual loading of the fixture.

[0041] In another embodiment, a pressure-holding block is provided on the side of the fixture cover plate 212 away from the fixture base plate 211. By providing a pressure-holding block on the side of the fixture cover plate 212 away from the fixture base plate 211, the fixture cover plate 212 can hold pressure on the attached device and PCB board after the device is attached, thereby improving the attachment quality of the device and PCB board.

[0042] See Figure 2 and Figure 3 As shown, in a specific embodiment, the vacuum adsorption unit 2111 includes a vacuum adsorption hole 21111. The first end of the vacuum adsorption hole 21111 is connected to the first side of the fixture base plate 211, and the second end of the vacuum adsorption hole 21111 can be connected to an external vacuum device. By providing the vacuum adsorption hole 21111 on the fixture base plate 211, and configuring the first end of the vacuum adsorption hole 21111 to be connected to the first side of the fixture base plate 211, and the second end to be connected to an external vacuum device, the mounting fixture can adsorb the PCB board onto the first side of the fixture base plate 211 through the vacuum adsorption hole 21111. This adsorption and fixation of the PCB board through the vacuum adsorption hole 21111 prevents displacement of the PCB board during device mounting, improving the mounting quality. Furthermore, the vacuum adsorption hole 21111 allows for quick fixation of the PCB board, enabling operators or automated equipment to perform subsequent mounting actions more rapidly, thus improving production efficiency.

[0043] In one optional embodiment, the vacuum adsorption holes 21111 provided in this embodiment are multiple, and the multiple vacuum adsorption holes 21111 are spaced apart on the fixture base plate 211.

[0044] In an optional embodiment, the vacuum adsorption unit 2111 provided in this embodiment further includes an adsorption channel. The adsorption channel provided in this embodiment is disposed in the fixture base plate 211, and the second ends of the plurality of vacuum adsorption holes 21111 are all connected to the adsorption channel. The adsorption channel can be connected to an external vacuum generating device.

[0045] In an optional embodiment, the vacuum adsorption unit 2111 provided in this embodiment further includes a duct connector 21112. The duct connector 21112 provided in this embodiment is installed on the fixture base plate 211 and communicates with the adsorption channel. An external vacuum generating device can communicate with the adsorption channel through the duct connector 21112, and then communicate with multiple vacuum adsorption holes 21111.

[0046] See Figures 1 to 4 As shown, in a specific embodiment, the fixture assembly 21 in this embodiment is provided with a guide hole, and the attachment fixture also includes a guide support part 30. The guide support part 30 includes a guide rod assembly 31, which is installed on the main body base plate 10 and slides in cooperation with the guide hole to guide the movement of the fixture assembly 21. A guide hole is provided on the fixture assembly 21, and a guide rod assembly 31 is provided on the main body base plate 10. The guide rod assembly 31 slides in the guide hole, which can improve the motion stability of the fixture assembly 21. Since the guide rod assembly 31 slides in the guide hole, it can guide the fixture base plate 211 to move along a predetermined straight trajectory. The cooperation between the guide rod assembly 31 and the guide hole makes the movement of the fixture base plate 211 more stable and linear, avoiding the decrease in bonding accuracy caused by shaking or offset. During the bonding process of the device, it may be affected by the vibration of external equipment or the inertial force generated by its own movement. The tight cooperation between the guide rod assembly 31 and the guide hole can effectively reduce the impact of these vibrations and shaking on the fixture base plate 211, so that the fixture base plate 211 maintains a relatively stable state during the movement, thereby ensuring that the bonding operation can be carried out in a stable environment and improving the bonding quality.

[0047] In an optional embodiment, the guide rod assembly 31 provided in this embodiment includes a guide rod body and a limiting sleeve. The first end of the guide rod body is fixedly connected to the main body base plate 10, and the second end of the guide rod body passes through the guide hole and at least partially protrudes from the first side of the fixture base plate 211. The limiting sleeve is located on the first side of the fixture base plate 211 and is fixedly connected to the first end of the guide rod body to restrict the fixture base plate 211 from moving away from the support assembly 22.

[0048] In one optional embodiment, the guide rod assembly 31 and the guide hole provided in this embodiment both extend along a first direction, wherein the first direction is parallel to the thickness direction of the main body base plate 10.

[0049] In one optional embodiment, the guide holes and guide rod assemblies 31 provided in this embodiment are multiple, the multiple guide holes are arranged at intervals along the circumference of the fixture assembly 21, and the multiple guide rod assemblies 31 correspond one-to-one with the multiple guide holes. By setting multiple guide holes and guide rod assemblies 31, and making the multiple guide rod assemblies 31 correspond one-to-one with the multiple guide holes, the movement stability of the fixture assembly 21 can be effectively improved.

[0050] In one optional embodiment, the guide hole provided in this embodiment is disposed on the jig base plate 211. The two opposite sides of the jig base plate 211 in the thickness direction are respectively the first side and the second side of the jig base plate 211. The thickness direction of the jig base plate 211 is parallel to the thickness direction of the main body base plate 10.

[0051] In an optional embodiment, a jig foot pad 11 is provided on the second side of the jig base plate 211 provided in this embodiment. Providing the jig foot pad 11 on the second side of the jig base plate 211 can increase the friction between the jig base plate 211 and the placement plane, and avoid direct contact between the main body base plate 10 and the placement plane, thereby improving the service life of the main body base plate 10.

[0052] In an optional embodiment, the jig base plate 211 provided in this embodiment has a rectangular or rounded corner cross-sectional profile in the second direction, wherein the second direction is perpendicular to the thickness direction of the main base plate 10. The guide holes and guide rod assemblies 31 provided in this embodiment are all four in number. The four guide holes are arranged at intervals along the circumference of the jig base plate 211 and correspond to the four corners of the jig base plate 211 respectively. The four guide rod assemblies 31 correspond one-to-one with the four guide holes. By setting four guide holes and four guide rod assemblies 31 and making the four guide rod assemblies 31 correspond one-to-one with the four guide holes, the movement stability of the jig assembly 21 can be effectively improved.

[0053] See Figures 1 to 4 As shown, in a specific embodiment, the guide support 30 in this embodiment further includes an elastic reset component 32, which is installed on the main body base plate 10 and is used to apply elastic force to the jig assembly 21 so that the jig assembly 21 can maintain the first state without the action of external force. An elastic reset component 32 is provided on the main body base plate 10, so that the jig assembly 21 can maintain its first state by the elastic force applied by the elastic reset component 32 when no external force is applied. This helps to maintain the relative positional relationship between the jig base plate 211 and the main body base plate 10, ensuring that the guide hole and guide rod assembly 31 always maintain a good fit. This ensures that the attachment jig can still guarantee the accuracy of the attachment position during long-term use, reducing attachment quality problems caused by positional deviation. In addition, when the jig base plate 211 collides with other components, the elastic reset component 32 can play a certain buffering role, preventing the jig base plate 211 from being damaged by rigid collision, extending the service life of the jig base plate 211. At the same time, the elastic reset component 32 can also absorb vibration and prevent vibration from being transmitted to the PCB board on the jig base plate 211.

[0054] In one optional embodiment, the main body base plate 10, the elastic reset component 32 and the fixture component 21 provided in this embodiment are arranged sequentially along the first direction. The elastic reset component 32 provided in this embodiment is sleeved on the guide rod component 31, and the two ends of the elastic component abut against the main body base plate 10 and the fixture component 21 respectively.

[0055] In one optional embodiment, the elastic reset component 32 provided in this embodiment is a plurality of such components, and the plurality of elastic reset components 32 correspond one-to-one with the plurality of guide rod components 31.

[0056] In one alternative embodiment, the elastic reset component 32 provided in this embodiment is a compression spring.

[0057] In one specific embodiment, the positioning slot 23 is used to place multiple devices. These devices are arranged sequentially along the length of the positioning hole 2113. The fixture assembly 21, driven by an external drive device, can bring the PCB board into contact with the device closest to the PCB board. Setting the positioning slot 23 to accommodate multiple devices reduces the frequency of repetitive operation steps, eliminating the need for frequent replacement of individual devices and saving operation time. Furthermore, the relative positions of multiple devices placed in the same positioning slot 23 can be precisely controlled through the groove design, improving the attachment accuracy of the fixture. Simultaneously, setting the positioning slot 23 to accommodate multiple devices reduces the number of attachment fixtures required for the same production scale compared to fixtures that can only accommodate a single device.

[0058] In one specific embodiment, the attachment fixture further includes an optical fiber sensor located at the bottom of the positioning groove 23. This sensor detects the presence of a device within the positioning groove 23. By placing the optical fiber sensor at the bottom of the positioning groove 23, the fixture can promptly alert the worker to add more devices after all devices within the positioning groove 23 have been attached, thus preventing any omissions.

[0059] In an optional embodiment, the fiber optic sensing unit provided in this embodiment includes a fiber optic sensing hole and a fiber optic sensor. The fiber optic sensing hole is disposed on the support assembly 22 and communicates with one end of the support assembly 22 near the fixture assembly 21, that is, communicates with the bottom wall of the positioning groove 23. The fiber optic sensor senses the device in the positioning groove 23 through the fiber optic sensing hole.

[0060] According to another aspect of this application, an attachment device is provided, the attachment device including an attachment fixture, the attachment fixture being the attachment fixture described above.

[0061] In summary, implementing the attachment fixture and attachment device provided in this embodiment has at least the following beneficial technical effects: The attachment fixture provided in this embodiment has a positioning hole 2113 on the fixture assembly 21 that connects the first side and the second side of the fixture assembly 21, and the support assembly 22 passes through at least partially from the second side of the fixture assembly 21 into the positioning hole 2113, so that the attachment fixture can form a positioning groove 23 for placing the device on the first side of the fixture assembly 21 through the end of the support assembly 22 near the fixture assembly 21 and the inner wall of the positioning hole 2113. When the device is placed in the positioning groove 23, the end of the support assembly 22 near the fixture assembly 21 can... The device is supported, and the inner wall of the positioning hole 2113 can limit the device, thereby ensuring that the device has high positional accuracy relative to the fixture assembly 21. When the external driving device drives the fixture assembly 21, the device in the positioning groove 23 is supported by the support assembly 22, so the device will not move with the movement of the fixture assembly 21. The PCB board mounted on the first side of the fixture assembly 21 will attach to the device as the fixture assembly 21 moves. Since the positioning groove 23 abuts and limits the device during the attachment process, it can ensure that the device is subjected to a more uniform force, thereby improving the attachment accuracy and reliability of the device.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
