Description

Technical Field

[0001] This invention relates to the field of differential pressure adjustment technology, and in particular to a differential pressure adjustment component and a pressure holding device. Background Technology

[0002] Currently, during the pressure holding process, the upper and lower shells of the earphone shells are often inspected with a video microscope to check if they are aligned, and then manually adjusted for alignment. However, when the upper and lower shells are fastened together, glue is needed to strengthen the connection, which can easily lead to glue overflow. Furthermore, the contour curve of the earphone shell is mostly curved, which can easily affect the acquisition of the shell contour by the video microscope and the orientation or position of the shell, thus affecting the alignment accuracy between the upper and lower shells and the product yield. Summary of the Invention

[0003] The main objective of this invention is to provide a differential adjustment component and a pressure holding device, which aim to improve the alignment accuracy and product yield of product pressing assembly.

[0004] To achieve the above objectives, the present invention provides a discontinuity adjustment component, comprising:

[0005] A pressure-holding fixture, comprising a bearing fixture and a pressing fixture, wherein the bearing fixture is used to fix a first component, and the pressing fixture is vertically mounted above the bearing fixture and used to fix a second component, and a pressing space is formed between the bearing fixture and the pressing fixture;

[0006] A visual acquisition mechanism, comprising at least two cameras arranged circumferentially along the pressure-holding fixture, with each camera facing the pressing space; and

[0007] A position adjustment mechanism is provided, which is kinetically connected to at least one of the bearing fixture and the pressing fixture to perform alignment adjustment on the bearing fixture and the pressing fixture so that the first component and the second component are aligned.

[0008] In one embodiment of this application, the position adjustment mechanism is connected to at least a portion of the bearing fixture via a transmission connection to adjust the placement state of the first component.

[0009] In one embodiment of this application, the discontinuity adjustment assembly further includes a tooling fixing mechanism, wherein the bearing tooling includes:

[0010] A base plate, which is fixed to the installation platform by the tooling fixing mechanism;

[0011] A flow fixture, disposed on the base plate and drively connected to the position adjustment mechanism, is used to fix the first component; and

[0012] A locking and releasing structure is disposed between the base plate and the flow tooling;

[0013] When no adjustment is needed for the flow tooling, the locking and releasing structure locks the flow tooling to the base plate. When adjustment is needed for the flow tooling, the locking and releasing structure releases the flow tooling so that the flow tooling can move relative to the base plate.

[0014] In one embodiment of this application, the position adjustment mechanism is located below the base plate, and the position adjustment mechanism is provided with one of a connector and a connector hole, and the bottom of the flow tool is provided with the other of a connector and a connector hole;

[0015] The base plate has a clearance hole, and the connector passes through the clearance hole and is inserted into the connector hole so that the position adjustment mechanism is connected to the flow tooling.

[0016] In one embodiment of this application, the connector is disposed on the position adjustment mechanism and is vertically adjustable. The cross-sectional area of ​​the free end of the connector gradually increases from bottom to top to form a tensioning portion, which is tensioned to the connector hole.

[0017] In one embodiment of this application, the locking and releasing structure includes a first magnetic element disposed on the base plate and a second magnetic element disposed on the flow tooling, wherein the first magnetic element and the second magnetic element attract each other.

[0018] In one embodiment of this application, the differential adjustment assembly further includes a magnet opening and closing mechanism, which is drively connected to at least one of the first magnetic element and the second magnetic element to bring the first magnetic element and the second magnetic element closer to or further away from each other.

[0019] In one embodiment of this application, the magnet opening and closing mechanism is disposed below the base plate, and the magnet opening and closing mechanism includes:

[0020] A clamping structure for clamping the first magnetic element; and

[0021] A lifting structure is provided, which is connected to the clamping mechanism to drive the clamping mechanism to move up and down.

[0022] In one embodiment of this application, the tooling fixing mechanism includes a clamping member for clamping the base plate.

[0023] In one embodiment of this application, the discontinuity adjustment component further includes an upper vision mechanism, which is disposed above the pressure holding fixture and faces the pressure holding fixture.

[0024] In one embodiment of this application, the camera is an area scan camera;

[0025] And / or, the position adjustment mechanism is an XYR axis adjustment mechanism.

[0026] This application also proposes a pressure-holding device, the pressure-holding device comprising a differential adjustment component as described in any of the preceding claims, the differential adjustment component comprising:

[0027] A pressure-holding fixture, comprising a bearing fixture and a pressing fixture, wherein the bearing fixture is used to fix a first component, and the pressing fixture is vertically mounted above the bearing fixture and used to fix a second component, and a pressing space is formed between the bearing fixture and the pressing fixture;

[0028] A visual acquisition mechanism, comprising at least two cameras arranged circumferentially along the pressure-holding fixture, with each camera facing the pressing space; and

[0029] A position adjustment mechanism is provided, which is kinetically connected to at least one of the bearing fixture and the pressing fixture to perform alignment adjustment on the bearing fixture and the pressing fixture so that the first component and the second component are aligned.

[0030] The technical solution of this invention includes a visual acquisition mechanism in the differential adjustment mechanism. This mechanism comprises at least two cameras arranged circumferentially along the pressure-holding fixture. Each camera captures a side image of the component. By using side image information from multiple cameras at different angles, the placement of the component is accurately determined. This arrangement avoids the problem of image accuracy being easily affected by glue overflow at the fastening position when images are captured from above the component. This allows for accurate determination of the placement of the first and / or second components, enabling precise adjustment of their placement and ensuring accurate alignment, thus improving the alignment accuracy of the product's press-fit connection. Furthermore, the differential adjustment assembly uses a position adjustment mechanism to move the supporting fixture and / or pressing fixture to adjust the placement of the first and / or second components. This position adjustment mechanism avoids the problem of low alignment accuracy that easily occurs with manual adjustment, further improving the alignment accuracy of the product's press-fit connection and increasing the product assembly yield.

[0051] The present invention proposes a gap adjustment component 100 for aligning and engaging the first and second components of a product.

[0052] Please refer to Figures 1 to 3 In some embodiments of the discontinuity adjustment component 100 of this application, the discontinuity adjustment component 100 includes:

[0053] The pressure holding fixture 10 includes a bearing fixture 11 and a pressing fixture 13. The bearing fixture 11 is used to fix a first component, and the pressing fixture 13 is vertically and flexibly disposed above the bearing fixture 11 and is used to fix a second component. A pressing space is formed between the bearing fixture 11 and the pressing fixture 13.

[0054] A visual acquisition mechanism 30, comprising at least two cameras 31 arranged circumferentially along the pressure-holding fixture 10, with each camera 31 facing the pressing space; and

[0055] A position adjustment mechanism 50 is drivenly connected to at least one of the bearing fixture 11 and the pressing fixture 13 to adjust the alignment of the bearing fixture 11 and the pressing fixture 13 so that the first component and the second component are aligned.

[0056] The differential adjustment assembly 100 proposed in this application is used in a pressure holding device 1000 to ensure accurate alignment between two interlocking components. Specifically, the differential adjustment assembly 100 includes a pressure holding fixture 10 for holding a product. The pressure holding fixture 10 includes a support fixture 11 for supporting a first component of the product and a pressing fixture 13 for fixing a second component of the product. The pressing fixture 13 is vertically movably positioned above the support fixture 11 to form a pressing space between the pressing fixture 13 and the support fixture 11. When the pressing fixture 13 is pressed down, the first and second components of the product are pressed together. Simultaneously, at least one of the support fixture 11 and the pressing fixture 13 is drively connected to a position adjustment mechanism 50. The position adjustment mechanism 50 can... The tooling connected to it in the drive is positioned horizontally, such as in position and / or orientation, so that when the first and second parts are not accurately aligned, the bearing tooling 11 and / or pressing tooling 13 can be adjusted to make the first and second parts accurately aligned. In this embodiment, the position adjustment mechanism 50 can be a translation mechanism, a rotation mechanism, or an XYR axis adjustment mechanism. Different translation mechanisms can be selected according to the actual movement and alignment requirements. The translation mechanism can drive the part to translate in only one direction, or it can drive the part to translate in two or more different directions. In some embodiments, an XYZ axis adjustment mechanism is used for directional translation. The horizontal plane is defined with an X-direction and a Y-direction set at an angle. The XYZ axis adjustment mechanism includes an X-axis translation structure 51, a Y-axis translation structure 53, and a rotation structure 55. Alternatively, the Y-axis translation structure 53 can be mounted on the X-axis translation structure 51, and the rotation structure 55 can be mounted on the Y-axis translation structure 53, with the rotation structure 55 connected to the component to be transmitted. Another option is to mount the X-axis translation structure 51 on the rotation structure 55, and then mount the Y-axis translation structure 53 on the X-axis translation structure 51, so that the component to be transmitted is aligned with the Y-axis... The specific combination of the translation structure 53, the X-axis translation structure 51, the Y-axis translation structure 53, and the rotation structure 55 is not limited here. It is only necessary to enable the XYR axis adjustment mechanism to drive the tooling connected to it to translate in the X and Y directions, and to drive the tooling connected to it to rotate along a rotating axis perpendicular to the horizontal plane. This can meet the placement adjustment requirements of different scenarios, improve the application flexibility of the differential adjustment component 100, and integrate the drive mechanism into a one-piece XYR axis adjustment mechanism, simplifying the structure of the differential adjustment component 100 and improving the ease of assembly.

[0057] Taking the load-bearing fixture 11 connected to the XYR axis adjustment mechanism as an example, if the second component fixed to the pressing fixture 13 remains in the same position, the position of the second component can be used as the alignment reference. When the first component and the second component to be fastened are not aligned, the XYR axis adjustment mechanism drives the load-bearing fixture 11 to move according to the deviation direction, distance or angle, thereby adjusting the position of the first component so that it is accurately aligned with the second component.

[0058] Similarly, when the pressing fixture 13 is connected to the XYR axis adjustment mechanism and the first component is fixed to the bearing fixture 11 in an unchanged position, the position of the first component can be used as the alignment reference. The XYR axis adjustment mechanism can then adjust the position of the second component by driving the pressing fixture 13 to move, so that the second component is accurately aligned with the first component.

[0059] Of course, two position adjustment mechanisms 50 can also be set, and the two position adjustment mechanisms 50 are respectively connected to the bearing fixture 11 and the pressing fixture 13. In this case, the alignment adjustment can be performed by driving at least one of the bearing fixture 11 and the pressing fixture 13 to move, or the bearing fixture 11 and the pressing fixture 13 can be moved at the same time for alignment adjustment. No specific limitation is made here.

[0060] Furthermore, when the supporting fixture 11 and the pressing fixture 13 are respectively movable and need to meet two or more position movement requirements, such as needing to translate in two or more directions or needing to simultaneously achieve translation and rotation, it is only necessary to ensure that the combination of the movement degrees of freedom of the supporting fixture 11 and the pressing fixture 13 includes the required movement degrees of freedom. For example, when it is necessary to meet the XYR three-axis movement requirements, the supporting fixture 11 can be translated in the X and Y directions, so that the pressing fixture 13 can at least rotate in the horizontal plane; or the supporting fixture 11 can be translated in the X direction, so that the pressing fixture 13 can at least translate in the Y direction and rotate in the horizontal plane; or the supporting fixture 11 and the pressing fixture 13 can both perform XYR three-axis movement at the same time. The specific implementation method is not limited here, that is, the two position adjustment mechanisms 50 that are respectively connected to the supporting fixture 11 and the pressing fixture 13 can be the same or different.

[0061] Furthermore, the discontinuity adjustment assembly 100 includes a vision acquisition mechanism 30, which is used to acquire images to determine the placement state of the first component and / or the second component. The vision acquisition mechanism 30 includes at least two cameras 31 arranged circumferentially along the support fixture 11, with each camera 31 facing the pressing space. This arrangement allows the vision acquisition mechanism 30 to acquire side image information of the component in at least two circumferential directions, thereby determining the placement state of the component based on the acquired side image information. The side image information acquired by each camera 31 can be the side outline of the product and / or the acquired side image within the visual range of the camera 31. The position of the product and the side profile can determine the placement orientation of the component, thereby determining the rotation angle required for component alignment. The position of the acquired side image within the visual range of camera 31 can determine the placement position of the component, thereby determining the direction and distance of translation required for component alignment. It is understood that the position of the side profile of the component will not be affected by excess glue at the component's fastening position. Therefore, even if there is excess glue at the component's fastening position, it will not affect the acquisition of the component's side image information. That is, compared to directly acquiring the outline of the component's fastening surface to determine the component's placement state, the placement state of the component can be determined more accurately based on the side images of the component from different orientations, thereby improving the alignment accuracy of the first and second components. In some embodiments, when the first component has a fixed orientation on the support fixture 11 and the second component has a fixed placement orientation on the pressing fixture 13, the placement state of the components can also be determined by acquiring image information from the support fixture 11 and / or the pressing fixture 13, which is not limited here.

[0062] It should also be noted that if the placement of the second component is used as a reference, and the placement of the first component is adjusted to align the first and second components, the placement of the second component must first be determined as a reference. In some embodiments, the placement of the second component can be determined by positioning the second component on the pressing fixture 13, in which case the placement of the second component remains unchanged by the mechanical positioning structure. Of course, the placement of the second component can also be determined by the vision acquisition mechanism 30 or the upper vision mechanism 90 in the following embodiments. For example, the upper vision mechanism 90 can collect the placement of the second component, and the vision acquisition mechanism 30 can collect the placement of the first component; or the vision acquisition mechanism 30 can collect the placement of the first and second components sequentially, and the order of collection is not limited; or the first and second components can be simultaneously placed within the field of view of the camera 31 to simultaneously collect the placement of the first and second components.

[0063] Similarly, if the placement of the first component is used as a reference and the placement of the second component is adjusted for alignment, the placement of the first component can be fixed by a mechanical positioning structure, or the placement of the first component can be determined by a vision acquisition mechanism 30. No specific limitations are made here.

[0064] Therefore, it is understood that in the technical solution of the present invention, the differential adjustment mechanism is provided with a visual acquisition mechanism 30. The visual acquisition mechanism 30 is provided with at least two cameras 31 arranged circumferentially along the pressure holding fixture 10. At this time, each camera 31 acquires a side image of the component. By using the side image information from different directions acquired by multiple cameras 31, the placement state of the component can be accurately determined. This setting avoids the problem that the image accuracy is easily affected by glue overflow at the fastening position when acquiring images from above the component. Thus, the placement state of the first component and / or the second component can be accurately determined, and the placement state of the first component and / or the second component can be accurately adjusted so that the first component and the second component are accurately aligned, thereby improving the alignment accuracy of the product pressing connection. In addition, in the differential adjustment assembly 100, the position adjustment mechanism 50 drives the carrying fixture 11 and / or the pressing fixture 13 to move to adjust the placement state of the first component and / or the second component. Through the position adjustment mechanism 50, the problem of low alignment accuracy that is easy to occur when manually adjusted is avoided. It can also improve the alignment accuracy of the product pressing connection and improve the product assembly yield.

[0065] Please refer to Figure 5 In some embodiments of this application, the position adjustment mechanism 50 is drivenly connected to at least a portion of the bearing fixture 11 to adjust the placement state of the first component.

[0066] This application employs a position adjustment mechanism 50 to align the bearing fixture 11 and the pressing fixture 13, thereby improving the alignment accuracy between the first component and the second component. It is understood that in the pressure holding device 1000 and the step adjustment assembly, the bearing fixture 11 is generally mounted on the mounting platform 310, while the pressing fixture 13 needs to be height-adjustable. If the position adjustment mechanism 50 is also connected to the pressing fixture 13 to simultaneously drive its lifting, translation, and rotation, the overall drive and connection structures would be complex, making the assembly of the step adjustment assembly 100 inconvenient. In this embodiment, the bearing fixture 11 is connected to the position adjustment mechanism 50. This is done by adjusting the placement of the first component to align the first component and the second component. The position adjustment mechanism 50 can also be mounted on or below the mounting platform 310 to be connected to the bearing fixture 11, simplifying the structure of the step adjustment assembly 100 and facilitating assembly.

[0067] Please refer to Figure 4 and Figure 5 In some embodiments of this application, the discontinuity adjustment assembly 100 further includes a tooling fixing mechanism 70, and the bearing tooling 11 includes:

[0068] Base plate 111, which is fixed to the installation platform 310 by the tooling fixing mechanism 70;

[0069] A flow fixture 113 is disposed on the base plate 111 and is drively connected to the position adjustment mechanism 50. The flow fixture 113 is used to fix the first component; and

[0070] Lock-release structure 115, wherein the lock-release structure 115 is disposed between the base plate 111 and the flow tooling 113;

[0071] When there is no need to adjust the flow tool 113, the locking and releasing structure 115 locks the flow tool 113 to the base plate 111. When the flow tool 113 needs to be adjusted, the locking and releasing structure 115 releases the flow tool 113 so that the flow tool 113 can move relative to the base plate 111.

[0072] In this embodiment, the supporting fixture 11 includes a base plate 111 and a flow fixture 113. The base plate 111 serves as the mounting foundation for the supporting fixture 11, and the flow fixture 113 is connected to the base plate 111 through a locking and releasing structure 115. This arrangement allows the supporting fixture 11 to form an integral structure, facilitating the installation and handling of the supporting fixture 11. At the same time, the flow fixture 113 is movably positioned relative to the base plate 111 and is connected to the position adjustment mechanism 50. This means that when the placement of the first component needs to be adjusted, only the flow fixture 113 needs to be moved, without moving the entire supporting fixture 11. At this time, the mounting position of the base plate 111 on the mounting platform 310 is fixed, so that the initial positioning is completed when installing the supporting fixture 11 and the pressing fixture 13, and collisions with surrounding mechanisms are avoided due to the overall movement of the supporting fixture 11.

[0073] Meanwhile, the locking and releasing structure 115 in the bearing fixture 11 can improve the positional stability of the flow fixture 113 during the pressure holding process. Specifically, when the placement of the first component needs to be adjusted and the alignment of the flow fixture 113 needs to be adjusted, the locking and releasing structure 115 releases the flow fixture 113, allowing the flow fixture 113 to move relative to the base plate 111. When the flow fixture 113 does not need to be adjusted, the locking and releasing structure 115 fixes the flow fixture 113 to the base plate 111, thereby preventing the flow fixture 113 from moving relative to the base plate 111. This ensures that the placement of the first component on the flow fixture 113 is fixed during the product pressure holding process, allowing the first component and the second component to maintain accurate alignment for pressing connection, thereby improving the connection accuracy and yield of the product. The locking and releasing structure 115 can be a magnetic structure, such as a permanent magnet attraction structure or an electromagnet attraction structure; it can also be a vacuum adsorption structure, a plug-in structure, a snap-fit ​​structure, a clamping structure, or any combination of two or more fixing structures, without limitation. In addition, the locking and releasing of the locking and releasing structure 115 can be manually operated, electrically controlled, pneumatically controlled, or controlled by a mechanical structure such as a robotic arm. For example, when using a plug-in structure, snap-fit ​​structure, clamping structure, permanent magnet attraction structure, etc., it can be operated manually or by a mechanical structure such as a robotic arm; when using an electromagnet attraction structure, the locking and releasing of the locking and releasing structure 115 can be controlled by turning the power on and off; when using a vacuum adsorption structure, it can be controlled by a pneumatic structure such as a vacuum generator, without specific limitation.

[0074] In addition, the base plate 111 is fixed on the installation platform 310 by setting a tooling fixing mechanism 70. The tooling fixing mechanism 70 can be a bolt, pin, magnetic structure, clamping structure, adsorption structure, or any combination of two or more fixing structures, without specific limitations.

[0075] Please refer to Figure 5 In some embodiments of this application, the position adjustment mechanism 50 is disposed below the base plate 111. The position adjustment mechanism 50 is provided with one of a connector 57 and a connector hole 1131. The bottom of the flow tooling 113 is provided with the other of a connector 57 and a connector hole 1131. The base plate 111 is provided with a clearance hole 1111. The connector 57 passes through the clearance hole 1111 and is inserted into the connector hole 1131, so that the position adjustment mechanism 50 is connected to the flow tooling 113.

[0076] Understandably, the technical solution of the aforementioned embodiment enables the position adjustment mechanism 50 to be connected to the flow tooling 113 on the bearing tooling 11, so as to adjust the placement state of the first component by driving the flow tooling 113 to make the first component and the second component accurately aligned. In this embodiment, the bottom plate 111 is provided with a clearance hole 1111, and the position adjustment mechanism 50 and the flow tooling 113 are connected and fixed by a plug-in structure of a plug-in member 57 and a plug-in hole 1131. Understandably, the position adjustment mechanism 50 is provided with a drive structure and a movable member. The movable member is connected to the flow tooling 113 so that the drive structure can drive the flow tooling 113 to move by driving the movable member. At this time, a plug-in member 57 or a plug-in hole 1131 can be provided on the movable member of the position adjustment mechanism 50, and a corresponding plug-in hole 1131 or a plug-in member 57 can be provided at the bottom of the flow tooling 113. The plug-in member 57 passes through the clearance hole 1111 on the bottom plate 111 to be inserted into the plug-in member. In the hole 1131, the movable part and the flow tool 113 are connected and fixed. If it is only necessary to drive the flow tool 113 to rotate by the position adjustment mechanism 50, that is, when the position adjustment mechanism 50 is a rotating mechanism, it is only necessary to allow the plug-in 57 to rotate in the clearance hole 1111. When it is necessary to drive the flow tool 113 to translate by the position adjustment mechanism 50, the cross section of the clearance hole 1111 must be larger than the plug-in 57, and the range of the clearance hole 1111 must be greater than or equal to the range of movement of the plug-in 57 when the flow tool 113 moves, so that the plug-in 57 can move in the clearance hole 1111 to meet the placement position adjustment of the flow tool 113 and avoid the base plate 111 restricting the movement of the flow tool 113.

[0077] In this embodiment, the connection method between the connector 57 and the connector hole 1131 can be interference fit, threaded fit, set screw fixation, etc., which is not limited here. In general, the connector 57 is detachably inserted into the connector hole 1131 so as to facilitate the disassembly and separation of the bearing fixture 11 and the position adjustment mechanism 50, and to facilitate the maintenance of the bearing fixture 11 and the position adjustment mechanism 50.

[0078] Please refer to Figure 5 and Figure 6 In some embodiments of this application, the plug-in 57 is disposed on the position adjustment mechanism 50 and is vertically adjustable. The cross-sectional area of ​​the free end of the plug-in 57 gradually increases from bottom to top to form a tensioning part 571, which is tensioned to the plug hole 1131.

[0079] In this embodiment, the connector 57 protrudes from the position adjustment mechanism 50 and extends upward to pass through the clearance hole 1111 and connect with the connector hole 1131. Specifically, the cross-sectional area of ​​the free end of the connector 57 that connects with the connector hole 1131 increases from bottom to top to form a tensioning part 571, and the maximum cross-sectional area of ​​the tensioning part 571 is greater than the diameter of the connector hole 1131. With this configuration, after the free end of the connector 57 passes through the connector hole 1131, the connector 57 is driven to descend, thereby causing the tensioning part 571 to be tensioned in the connector hole 1131 and to have an interference fit with the connector hole 1131, thereby connecting and fixing the movable part and the flow tooling 113. When it is necessary to disassemble the bearing tooling 11, it is only necessary to drive the connector 57 upward to release the connection between the connector 57 and the connector hole 1131. The connector 57 can be raised and lowered. It can be that only the connector 57 is raised and lowered on the position adjustment mechanism 50, or the entire position adjustment mechanism 50 can be raised and lowered. There is no limitation here.

[0080] Please refer to Figure 7 and Figure 8 In some embodiments of this application, the locking and releasing structure 115 includes a first magnetic element 1151 disposed on the base plate 111 and a second magnetic element 1153 disposed on the flow tooling 113, wherein the first magnetic element 1151 and the second magnetic element 1153 attract each other.

[0081] In the aforementioned embodiment, the supporting fixture 11 is formed by combining a base plate 111 and a flow fixture 113. The flow fixture 113 is fixed to the base plate 111 by a locking and releasing structure 115, allowing the flow fixture 113 to move relative to the base plate 111 by releasing the locking and releasing structure 115. In this embodiment, the locking and releasing structure 115 is a magnetic attraction structure, including a first magnetic element 1151 and a second magnetic element 1153. The first magnetic element 1151 is disposed on the base plate 111, and the second magnetic element 1153 is disposed on the flow fixture 113, so that the flow fixture 113 and the base plate 111 are connected by the magnetic attraction of the first magnetic element 1151 and the second magnetic element 1153. In this case, both the first magnetic element 1151 and the second magnetic element 1153 can be set as magnets, or only one of the first magnetic element 1151 and the second magnetic element 1153 can be set as a magnet. One of the components can be configured as a magnetically conductive element that can attract a magnet; this is not limited to any particular type of magnet, which can be a permanent magnet or an electromagnet. When it is necessary to release the lock between the base plate 111 and the flow fixture 113 to allow the flow fixture 113 to move, the first magnetic component 1151 and the second magnetic component 1153 can be moved away from each other to reduce the magnetic attraction between them. When using an electromagnet, the power can be turned off to demagnetize it, thus preventing the first magnetic component 1151 and the second magnetic component 1153 from attracting each other. In this embodiment, a magnetic structure is used as the locking and releasing structure 115, which is more convenient for locking and releasing the connection between the flow fixture 113 and the base plate 111 compared to methods such as buckles and screws.

[0082] In some embodiments, the locking-release structure 115 includes a magnetic attraction structure formed by multiple pairs of cooperating first magnetic elements 1151 and second magnetic elements 1153. This structure enhances the connection strength between the flow-through fixture 113 and the base plate 111 when the base plate 111 and the flow-through fixture 113 are connected and fixed. This prevents the flow-through fixture 113 from shifting on the base plate 111 without adjustment, ensuring that the first component on the flow-through fixture 113 remains in a fixed position during product pressure holding. This allows the first and second components to maintain accurate alignment for press-fit connection, improving the connection accuracy and yield of the product. Additionally, refer to... Figure 8 This allows the first magnetic component 1151 and the second magnetic component 1153 to maintain a plug-in fit when they attract each other, which can increase the magnetic attraction area between the first magnetic component 1151 and the second magnetic component 1153, thereby increasing the connection strength between the first magnetic component 1151 and the second magnetic component 1153. It can also improve the connection strength between the flow tooling 113 and the base plate 111.

[0083] Please refer to Figure 3 and Figure 10In some embodiments of this application, the differential adjustment assembly 100 further includes a magnet opening and closing mechanism 80, which is tractively connected to at least one of the first magnetic element 1151 and the second magnetic element 1153 to bring the first magnetic element 1151 and the second magnetic element 1153 closer to or further away from each other.

[0084] Understandably, the magnetic attraction between the first magnetic element 1151 and the second magnetic element 1153 decreases as the distance between them increases. In this embodiment, a magnet opening and closing mechanism 80 is provided to drive the first magnetic element 1151 and the second magnetic element 1153 closer to or further apart. This can be achieved by connecting the magnet opening and closing mechanism 80 to the first magnetic element 1151, the second magnetic element 1153, or both simultaneously. Thus, when the flow tooling 113 needs to be movable, it can be opened and closed by the magnet. The coupling mechanism 80 moves the first magnetic component 1151 and the second magnetic component 1153 away from each other to reduce the magnetic attraction between them. This makes the driving force applied by the position adjustment mechanism 50 to the flow tool 113 greater than the magnetic attraction, thus driving the flow tool 113 to move and adjust the placement of the first component. Alternatively, the first magnetic component 1151 and the second magnetic component 1153 can be moved away from each other along the arrangement direction of the base plate 111 and the flow tool 113, or they can be staggered, which can also reduce the magnetic attraction.

[0085] In some embodiments, the locking and releasing structure 115 includes a magnetic attraction structure formed by multiple pairs of mutually cooperating first magnetic elements 1151 and second magnetic elements 1153. In this case, the magnet opening and closing mechanism 80 can simultaneously drive multiple pairs of first magnetic elements 1151 and second magnetic elements 1153 to move away from each other and closer to each other. Alternatively, multiple magnet opening and closing mechanisms 80 can be provided to correspond to multiple pairs of magnetic attraction structures respectively, which is not limited here.

[0086] Please refer to Figure 10 In some embodiments of this application, the magnet opening and closing mechanism 80 is disposed below the base plate 111, and the magnet opening and closing mechanism 80 includes:

[0087] Clamping structure 81, the clamping structure 81 being used to clamp the first magnetic element 1151; and

[0088] A lifting structure 83 is connected to the clamping mechanism to drive the clamping mechanism to rise and fall.

[0089] In this embodiment, the magnet opening and closing mechanism 80 is located below the base plate 111 to drive the first magnetic component 1151 closer to and further away from the second magnetic component 1153. The magnet opening and closing mechanism 80 includes a clamping structure 81 and a lifting structure 83. The clamping structure 81 has a clamping space for clamping the first magnetic component 1151. The clamping space can be formed by at least two clamping arms 811 that can move closer to and further away from each other. The lifting structure 83 drives the clamping structure 81 to move up and down to move closer to or further away from the base plate 111. At this time, when it is necessary to make the flow tooling 113 movable, the lifting structure 83 drives the clamping structure 81 to rise, so that... The clamping structure 81 approaches and clamps the first magnetic component 1151. Then, the lifting structure 83 drives the clamping structure 81 to descend, carrying the first magnetic component 1151 away from the second magnetic component 1153, thus reducing the magnetic attraction between the two components. After the flow fixture 113 is adjusted, the lifting structure 83 drives the clamping structure 81 to rise, causing the first magnetic component 1151 to approach the second magnetic component 1153 and attract, thereby securing the flow fixture 113 to the base plate 111 and maintaining its stable position on the base plate 111. The driving component 75 that drives the clamping arms 811 to move closer and further apart can be a pneumatic gripper, or it can be a motor or other driving component 75 connected to the clamping arms 811 via a linkage mechanism, gear and rack mechanism, etc. No limitation is made here.

[0090] In some embodiments, the end of the clamping arm 811 of the clamping mechanism extends inward into the clamping space to form a hook 813. When the clamping structure 81 clamps the first magnetic element 1151, the hook 813 hooks onto the surface of the first magnetic element 1151 facing the second magnetic element 1153, thereby improving the stability of the clamping structure 81 when clamping the first magnetic element 1151 away from the second magnetic element 1153, and preventing the first magnetic element 1151 from detaching from the clamping structure 81 and approaching the second magnetic element 1153 under the action of magnetic attraction. At this time, a gap needs to be provided between a portion of the edge of the first magnetic element 1151 and the base plate 111 to form a clearance space for the hook 813 to enter and exit.

[0091] Please refer to Figure 8In some embodiments, a limiting hole 1113 is provided on the surface of the base plate 111 facing away from the flow tool 113. The limiting hole 1113 can be a through hole that passes through the base plate 111 or a blind hole that does not pass through, and is not limited here. The first magnetic element 1151 is movably disposed in the limiting hole 1113, and a portion of the first magnetic element 1151 protrudes from the limiting hole 1113 to form a clamping part 1151a that can be clamped by the clamping structure 81, so that the first magnetic element 1151 can move closer to and away from the second magnetic element 1153 along the axial direction of the limiting hole 1113, and keep the first magnetic element 1151 in a stable mounting position on the base plate 111. Alternatively, the cross-sectional area of ​​the clamping part 1151a can be larger than the diameter of the limiting hole 1113. The clamping part 1151a can abut against the outside of the opening of the limiting hole 1113 to limit the depth of the first magnetic element 1151 inserted into the limiting hole 1113, preventing the first magnetic element 1151 from completely entering the limiting hole 1113 and thus being unable to be clamped by the clamping structure 81. Furthermore, when the clamping arm 811 of the clamping structure 81 is provided with a claw 813, a limiting protrusion 1115 can be provided on the surface of the base plate 111 facing away from the flow tool 113 for abutting against the clamping part 1151a, thereby creating a clearance space between a portion of the edge of the first magnetic element 1151 and the base plate 111 to allow the claw 813 to enter and exit.

[0092] Please refer to Figure 4 , Figure 5 as well as Figure 11 In some embodiments of this application, the tooling fixing mechanism 70 includes a clamping member 71, which is used to clamp the base plate 111.

[0093] In this embodiment, the tooling fixing mechanism 70 is provided with a clamping member 71, which is used to clamp and fix the base plate 111 to prevent the base plate 111 from moving on the mounting surface. The clamping member 71 can be connected to the mounting platform 310 by bolts to press the base plate 111, or, as in the following embodiment, a lifting mechanism can drive one end of the clamping member 71 to swing up and down, so that the pressing section of the clamping member 71 presses down to clamp the base plate 111. In some embodiments, the tooling fixing mechanism 70 can be provided with multiple clamping members 71, which are distributed circumferentially along the base plate 111 to press the base plate 111 in different directions. This increases the clamping force on the base plate 111 and subjectes the base plate 111 to multiple circumferential limiting movements, improving the fixing strength and stability of the base plate 111.

[0094] Please refer to Figure 11 In some embodiments of this application, the tooling fixing mechanism 70 further includes:

[0095] Support member 73, clamping member 71 is rotatably connected to support member 73, the rotation axis of clamping member 71 extends horizontally, and the end of clamping member 71 away from support member 73 forms a clamping end; and

[0096] A driving component 75 is connected to the clamping component 71 for driving the clamping component 71 to rotate so that the clamping end presses against or releases the base plate 111.

[0097] In this embodiment, the tooling fixing mechanism 70 includes a clamping member 71, a support member 73, and a driving member 75. The support member 73 is used to fix it on the mounting platform 310. The clamping member 71 is rotatably connected to the support member 73 and is transmitted to the driving member 75 so that the clamping member 71 can rotate under the drive of the driving member 75. At this time, the clamping end of the clamping member 71 moves up and down, thereby driving the clamping member 71 to rotate so that the clamping end presses down to press the base plate 111. Alternatively, when the clamping member 71 rotates in the opposite direction, the clamping end is lifted to loosen the base plate 111, so that the bearing tooling 11 can be disassembled.

[0098] In some embodiments, the clamping member 71 has a clamping end and a driving end, and the rotating shaft of the clamping member 71 is located between the two ends. At this time, the driving member 75 is connected to the driving end for driving the driving end to rise or fall, thereby causing the clamping end to press down or rise. It can be understood that by using the clamping member 71 to press the base plate 111, there is no need to process the connecting structure on the base plate 111, which simplifies the structure of the base plate 111 and improves the processing convenience of the base plate 111.

[0099] In this embodiment, the driving component 75 can be a motor, a cylinder, or a hydraulic cylinder, etc. The transmission connection between the driving component 75 and the clamping component 71 can be such that the driving component 75 and the clamping component 71 are directly connected, for example, the output shaft of the motor is connected to the rotating shaft of the clamping component 71, or the piston rod of the cylinder or hydraulic cylinder is connected to the driving end of the clamping component 71. Of course, the driving component 75 and the clamping component 71 can also be connected by a transmission structure such as gear transmission, belt transmission, rack and pinion transmission, linkage transmission, or a combination of at least two transmission mechanisms, which is not limited here.

[0100] Please refer to Figure 2 and Figure 3 In some embodiments of this application, the differential adjustment component 100 further includes an upper vision mechanism 90, which is disposed above the pressure holding fixture 10 and faces the pressure holding fixture 10.

[0101] The technical solution of this application uses a vision acquisition mechanism 30 composed of at least two cameras 31 to determine the placement state of the components to be fastened, so as to accurately judge the placement state of the first component and / or the second component, thereby accurately adjusting the placement state of the first component and / or the second component, so that the first component and the second component are accurately aligned, improving the fastening accuracy between the first component and the second component. In this embodiment, the discontinuity adjustment component 100 also includes an upper vision mechanism 90, which can be a CCD camera or an area array camera. The upper vision mechanism 90 is set above the pressure holding fixture 10. The setting of the upper vision mechanism 90 can collect image information above the first component and the second component, thereby integrating the image information collected by the upper vision mechanism 90 and the vision acquisition mechanism 30 and cross-referencing them to improve the accuracy of judging the placement state of the first component and the second component, and further improve the fastening alignment accuracy of the first component and the second component.

[0102] In this embodiment, the upper vision mechanism 90 can acquire image information by acquiring the placement orientation and position of the pressing fixture 13 and the supporting fixture 11, thereby determining the placement status of the first component and the second component based on the placement status information of the pressing fixture 13 and the supporting fixture 11. Alternatively, an observation hole 131 can be opened on the pressing fixture 13 to directly acquire the placement status of the first component and / or the second component, so as to avoid the setting of the pressing fixture 13 from blocking the upper vision mechanism 90 from acquiring images of the first component or the second component.

[0103] In some embodiments, the upper vision mechanism 90 may be used only to collect the placement state of the second component, while the vision acquisition mechanism 30 may collect the placement state of the first component or the placement state of the second component at the same time, without limitation.

[0104] In some embodiments of this application, the camera 31 is an area array camera 31.

[0105] The technical solution of this application determines the placement orientation of the components to be fastened by a visual acquisition mechanism 30 composed of at least two cameras 31, thereby improving the fastening accuracy between the two components. In this embodiment, the cameras 31 set in the visual acquisition mechanism 30 are area scan cameras 31. The area scan camera 31 mainly uses continuous, planar scanning light to detect the product. It can acquire images at once and perform image acquisition in a timely manner, and the image acquisition accuracy is high, so as to accurately distinguish the side images acquired by each camera 31, thereby accurately determining the placement orientation of the first component or the second component.

[0106] Please refer to Figure 9 In some embodiments of this application, the position adjustment mechanism 50 is an XYR axis adjustment mechanism.

[0107] In this embodiment, an XYZ axis adjustment mechanism is used as the position adjustment mechanism 50. The horizontal plane is defined with an X direction and a Y direction set at an angle. The XYZ axis adjustment mechanism includes an X-axis translation structure 51, a Y-axis translation structure 53, and a rotation structure 55. Alternatively, the Y-axis translation structure 53 can be mounted on the X-axis translation structure 51, and the rotation structure 55 can be mounted on the Y-axis translation structure 53, with the rotation structure 55 connected to the component to be driven. Another option is to mount the X-axis translation structure 51 on the rotation structure 55, and then mount the Y-axis translation structure 53 on the X-axis translation structure 51, so that the component to be driven is connected to the Y-axis translation structure 51. The specific combination of the X-axis translation structure 51, Y-axis translation structure 53, and rotation structure 55 is not limited here. It is only necessary to enable the XYR axis adjustment mechanism to drive the tooling connected to it to translate in the X and Y directions, and to drive the tooling connected to it to rotate along a rotating axis perpendicular to the horizontal plane. This can meet the placement adjustment requirements of different scenarios, improve the application flexibility of the differential adjustment component 100, and integrate the drive mechanism into an integrated XYR axis adjustment mechanism, simplifying the structure of the differential adjustment component 100 and improving the ease of assembly.

[0108] Please refer to Figure 1 This application also proposes a pressure holding device 1000, which includes a frame 300 and a differential adjustment component 100 as described in any of the preceding claims. The frame 300 serves as an installation base for mounting the differential adjustment component 100 and control devices of the pressure holding device 1000, such as electronic control devices. The differential adjustment assembly 100 includes a pressure-holding fixture 10, a vision acquisition mechanism 30, and a position adjustment mechanism 50. The pressure-holding fixture 10 includes a support fixture 11 and a pressing fixture 13. The support fixture 11 is used to fix the first component, and the pressing fixture 13 is vertically and vertically disposed above the support fixture 11 and is used to fix the second component. A pressing space is formed between the support fixture 11 and the pressing fixture 13. The vision acquisition mechanism 30 includes at least two cameras 31, which are arranged circumferentially along the pressure-holding fixture 10, and each camera 31 is positioned facing the pressing space to capture the product outline on the pressure-holding fixture 10. The position adjustment mechanism 50 is drivenly connected to at least one of the support fixture 11 and the pressing fixture 13 to perform alignment adjustment of the support fixture 11 and the pressing fixture 13.

[0109] The pressure holding device 1000 of this application uses the differential adjustment component 100 proposed in any of the foregoing embodiments, which enables accurate alignment between two interlocking parts of the product and improves product yield. Specifically, the differential adjustment mechanism includes a vision acquisition mechanism 30, which has at least two cameras 31 arranged circumferentially along the pressure-holding fixture 10. Each camera 31 acquires a side image of the component, allowing for accurate determination of the component's placement status through side image information from different angles acquired by multiple cameras 31. This configuration avoids the problem of image accuracy being easily affected by glue overflow at the fastening position when acquiring images from above the component, thus accurately determining the placement status of the first and / or second components. This allows for precise adjustment of the placement status of the first and / or second components, ensuring accurate alignment and improving the alignment accuracy of the product pressing connection. Furthermore, the differential adjustment assembly 100 uses a position adjustment mechanism 50 to move the carrying fixture 11 and / or the pressing fixture 13 to adjust the placement status of the first and / or second components. The position adjustment mechanism 50 avoids the problem of low alignment accuracy that easily occurs when manually adjusted, also improving the alignment accuracy of the product pressing connection and increasing the product assembly yield.

[0110] Since the pressure holding device 1000 proposed in this application applies all the technical solutions of all the aforementioned embodiments of the differential adjustment component 100, it has at least all the beneficial effects brought by all the aforementioned technical solutions, which will not be elaborated here.

[0111] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
