Description

Technical Field

[0001] This invention relates to the field of dispensing machine technology, and in particular to a dual-valve asynchronous dispensing machine. Background Technology

[0002] A dispensing machine is a machine that uses dispensing modules such as screw valves, dispensing needles, and piezoelectric valves to dispense adhesive. The dispensing modules need to be moved in the XYZ directions to dispense adhesive.

[0003] Existing dispensing machines use gantry-type moving devices to move the dispensing modules. One gantry controls the movement of one dispensing module. When two dispensing modules need to be dispensed asynchronously, two gantry sets are required, resulting in large equipment space occupation and low operation efficiency.

[0004] Under the above circumstances, there is an urgent need for a dual-valve asynchronous dispensing machine that occupies a small space and has high operating efficiency. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a dual-valve asynchronous dispensing machine, which can install a secondary valve moving device and a secondary dispensing module on the main valve moving device. The main and secondary dispensing modules can move separately along different asynchronous dispensing paths, which has the advantages of small equipment footprint and high operating efficiency. During the movement of the main dispensing module and the secondary dispensing module, part of the dispensing path overlaps. The secondary dispensing module is driven by both the main valve moving device and the secondary valve moving device simultaneously, resulting in faster speed.

[0006] This invention provides a dual-valve asynchronous dispensing machine, including a frame, a main valve moving device, a main dispensing module, a secondary valve moving device, and a secondary dispensing module; The fixed part of the main valve moving device is mounted on the frame, the fixed part of the auxiliary valve moving device and the main dispensing module are both mounted on the moving part of the main valve moving device, and the auxiliary dispensing module is mounted on the moving part of the auxiliary valve moving device; The main valve moving device is used to drive the main dispensing module, the secondary valve moving device, and the secondary dispensing module to move together. The secondary valve moving device is used to drive the secondary dispensing module to move asynchronously relative to the main dispensing module.

[0007] Furthermore, the auxiliary valve moving device includes an auxiliary valve fixed straight plate, an auxiliary valve X bending plate, an auxiliary valve Y bending plate, and an auxiliary valve Z straight plate; The auxiliary valve X bending plate and the auxiliary valve Y bending plate are mounted together vertically along the Z-axis. The auxiliary valve fixing plate and the auxiliary valve Z straight plate are respectively mounted on the side of the auxiliary valve X bending plate and the auxiliary valve Y bending plate in the same direction. The auxiliary valve fixing plate is located above the auxiliary valve Z straight plate along the Z-axis.

[0008] Furthermore, the two ends of the auxiliary valve fixing plate are positioned across the moving part of the main valve moving device and above the auxiliary valve Z-plate.

[0009] Furthermore, both the auxiliary valve X bending plate and the auxiliary valve Y bending plate are L-shaped bending plates comprising mutually perpendicular vertical plates and bottom plates. The bottom plates of the auxiliary valve X bending plate and the auxiliary valve Y bending plate are slidably mounted together. The vertical plates of the auxiliary valve X bending plate and the auxiliary valve Y bending plate are parallel and arranged in the same lateral direction.

[0010] Furthermore, the auxiliary valve fixed straight plate is slidably mounted on the upright plate of the auxiliary valve X bent plate, and the auxiliary valve Z straight plate is slidably mounted on the upright plate of the auxiliary valve Y bent plate.

[0011] Furthermore, the secondary valve moving device also includes a secondary valve X-axis moving assembly, a secondary valve Y-axis moving assembly, and a secondary valve Z-axis moving assembly; The fixed part of the auxiliary valve X-direction moving assembly is fixedly connected to the auxiliary valve fixed straight plate, and the moving part of the auxiliary valve X-direction moving assembly is fixedly connected to the auxiliary valve X-bending plate. The auxiliary valve X-direction moving assembly is used to drive the auxiliary valve X-bending plate to move relative to the auxiliary valve fixed straight plate in the X direction. The fixed part of the auxiliary valve Y-direction moving assembly is fixedly connected to the auxiliary valve X-bending plate, and the moving part of the auxiliary valve Y-direction moving assembly is fixedly connected to the auxiliary valve Y-bending plate. The auxiliary valve Y-direction moving assembly is used to drive the auxiliary valve Y-bending plate to move relative to the auxiliary valve X-bending plate in the Y direction. The fixed part of the secondary valve Z-direction moving assembly is fixedly connected to the secondary valve Y-bent plate, and the moving part of the secondary valve Z-direction moving assembly is fixedly connected to the secondary valve Z-straight plate. The secondary valve Z-direction moving assembly is used to drive the secondary valve Z-straight plate to move relative to the secondary valve Y-bent plate in the Z direction.

[0012] Furthermore, the secondary valve Z-direction moving assembly includes a secondary valve Z-direction driving mechanism. The secondary valve Y-bent plate has a first through groove on the side plate wall that abuts against the secondary valve Z-straight plate. The fixed part of the secondary valve Z-direction driving mechanism is located on the inside of the bend of the side plate wall of the secondary valve Y-bent plate. The moving part of the secondary valve Z-direction driving mechanism passes through the first through groove and connects to the secondary valve Z-straight plate.

[0013] Furthermore, the secondary valve Z-axis moving assembly also includes a first connector, one end of which is fixedly connected to the moving part of the secondary valve Z-axis driving mechanism, and the other end passes through the first through groove and is fixedly connected to the secondary valve Z-axis straight plate.

[0014] Furthermore, the secondary valve Y-direction moving assembly includes a secondary valve Y-direction driving mechanism. A second through groove is provided on the side plate wall of the secondary valve X-bending plate that abuts against the secondary valve Y-bending plate. The fixing part of the secondary valve Y-direction driving mechanism is located on the inner side of the bend of the side plate wall of the secondary valve X-bending plate. The moving part of the secondary valve Y-direction driving mechanism passes through the second through groove and connects to the secondary valve Y-bending plate.

[0015] Furthermore, the secondary valve Y-direction moving assembly also includes a second connector, one end of which is fixedly connected to the moving part of the secondary valve Y-direction driving mechanism, and the other end passes through the second through groove and is fixedly connected to the secondary valve Y-bending plate.

[0016] Furthermore, the secondary valve X-direction moving assembly includes a secondary valve X-direction drive motor, a transmission mechanism, and a spring plate; The auxiliary valve X-direction drive motor is fixedly connected to the auxiliary valve fixed plate, and the transmission mechanism is drivenly connected to the auxiliary valve X-direction drive motor to convert the rotation of the auxiliary valve X-direction drive motor into movement along the X direction; The spring is configured to be parallel to the side of the auxiliary valve fixing plate and the auxiliary valve X bending plate, and the two ends of the spring are fixedly connected to the transmission mechanism and the auxiliary valve X bending plate, respectively.

[0017] Furthermore, the sides of the spring plate, the auxiliary valve fixing plate, and the auxiliary valve X bending plate are all parallel to the ZX plane. After being subjected to force, the spring plate swings and twists along the Y-axis direction to correct the radial error of the sides of the auxiliary valve fixing plate and the auxiliary valve X bending plate in the Y-axis direction.

[0018] Furthermore, the auxiliary valve X-axis moving assembly also includes a third guide rail, which is a linear guide rail. The third guide rail is disposed between the auxiliary valve X-axis bent plate and the auxiliary valve fixed straight plate, and the sliding direction of the third guide rail is parallel to the X-axis direction. The fixed part of the third guide rail is fixedly connected to the fixed straight plate of the auxiliary valve, and the movable part of the third guide rail is fixedly connected to the side of the spring piece and the bending plate of the auxiliary valve.

[0019] Furthermore, the transmission mechanism includes a coupling, a lead screw, a nut seat, and a third connecting member. The two ends of the coupling are fixedly connected to the X-direction drive motor of the auxiliary valve and the lead screw, respectively, and the nut seat is slidably mounted on the lead screw. One end of the third connector is fixedly connected to the nut seat, and the other end is fixedly connected to the spring piece.

[0020] Furthermore, both the main dispensing module and the auxiliary dispensing module include one or more of a screw valve, a dispensing needle, and a piezoelectric valve. The moving part of the main valve moving device and / or the moving part of the auxiliary valve moving device are also provided with one or more of a sensor, a UV curing lamp, and a visual inspection device.

[0021] In summary, this embodiment of the invention, by installing the secondary valve moving device and the secondary dispensing module on the main valve moving device, allows the two dispensing modules to move along different asynchronous dispensing paths, offering advantages such as small equipment footprint and high operational efficiency. During the movement of the main and secondary dispensing modules, some dispensing paths overlap, and the secondary dispensing module is simultaneously driven by both the main and secondary valve moving devices, resulting in even faster speed.

[0022] Furthermore, the auxiliary valve moving device includes an auxiliary valve fixed straight plate, an auxiliary valve X-bending plate, an auxiliary valve Y-bending plate, and an auxiliary valve Z-straight plate. The auxiliary valve X-bending plate and the auxiliary valve Y-bending plate are mounted vertically together along the Z-axis. The auxiliary valve fixed straight plate and the auxiliary valve Z-straight plate are respectively mounted on the sides of the auxiliary valve X-bending plate and the auxiliary valve Y-bending plate in the same direction. The auxiliary valve fixed straight plate is positioned above the auxiliary valve Z-straight plate along the Z-axis. The auxiliary valve fixed straight plate, the auxiliary valve X-bending plate, the auxiliary valve Y-bending plate, and the auxiliary valve Z-straight plate are stacked as four modular designs in a cubic shape, resulting in a compact structure. This design reduces the weight of the auxiliary valve moving device, increases the moving speed of the main valve moving device driving the auxiliary dispensing module, reduces accuracy errors caused by vibration during heavy-mass movements, and also reduces the space occupied by the auxiliary valve moving device while increasing the moving stroke of the main valve moving device.

[0023] Furthermore, the two ends of the auxiliary valve fixed plate are positioned horizontally above the moving part of the main valve moving device and above the auxiliary valve Z-plate. The main dispensing module and the auxiliary dispensing module are arranged side by side on the moving part of the main valve moving device and the auxiliary valve Z-plate. The area below the main dispensing module and the auxiliary dispensing module is two dispensing positions. Driven by the main valve moving device and the auxiliary valve moving device, the two dispensing modules perform asynchronous dispensing at the two dispensing positions respectively.

[0024] Furthermore, both the X-shaped and Y-shaped bending plates of the secondary valve are L-shaped bending plates. The Y-axis moving assembly and the Z-axis moving assembly of the secondary valve are respectively located on the inner side of the bending plates of the X and Y, maximizing the use of the space occupied by the two bending plates. This further reduces the space occupied by the secondary valve moving device.

[0025] Furthermore, the secondary valve X-axis moving assembly includes a secondary valve X-axis drive motor, a transmission mechanism, and a spring. The spring is designed to be parallel to the sides of the secondary valve fixed straight plate and the secondary valve X-axis bent plate, with both ends of the spring fixedly connected to the transmission mechanism and the secondary valve X-axis bent plate, respectively. The spring is an elastic connecting component, reducing radial errors caused by the machining or assembly of structural parts and improving the smoothness of the mechanism. When the secondary valve fixed straight plate and the secondary valve X-axis bent plate are assembled, they are installed along the Y-axis. Therefore, there are assembly or machining errors between the secondary valve fixed straight plate and the secondary valve X-axis bent plate in the Y-axis direction. The spring can bend along the Y-axis to compensate for this error, and since the spring moves in the X-axis direction, the bending of the spring does not affect the transmission effect.

[0040] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. Based on the description of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0043] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0044] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0045] The following detailed explanation uses specific examples: like Figures 1 to 6 As shown, this embodiment of the invention provides a dual-valve asynchronous dispensing machine, including a frame 10, a main valve moving device 20, a main dispensing module 30, a secondary valve moving device 40, and a secondary dispensing module 50; like Figure 2 As shown, the fixed part of the main valve moving device 20 is mounted on the frame 10, the fixed part of the auxiliary valve moving device 40 and the main dispensing module 30 are both mounted on the moving part of the main valve moving device 20, and the auxiliary dispensing module 50 is mounted on the moving part of the auxiliary valve moving device 40. The main valve moving device 20 is used to drive the main dispensing module 30, the auxiliary valve moving device 40 and the auxiliary dispensing module 50 to move together. The auxiliary valve moving device 40 is used to drive the auxiliary dispensing module 50 to move asynchronously relative to the main dispensing module 30.

[0046] In this embodiment, the main valve moving device 20 includes a mounting plate 21, a main valve Z-axis drive mechanism 22, a cantilever 23, a Y-axis platform 24, a main valve Y-axis drive mechanism 25, an X-axis platform 26, and a main valve X-axis drive mechanism 27.

[0047] The fixed part of the main valve Z-axis drive mechanism 22 is mounted on the cantilever 23, and the mounting plate 21 is mounted on the moving part of the main valve Z-axis drive mechanism 22. The main valve Z-axis drive mechanism 22 is used to drive the mounting plate 21 to move along the Z-axis direction.

[0048] The fixed part of the main valve Y-axis drive mechanism 25 is mounted on the Y-axis platform 24, and the cantilever 23 is mounted on the moving part of the main valve Y-axis drive mechanism 25. The main valve Y-axis drive mechanism 25 is used to drive the cantilever 23, the main valve Z-axis drive mechanism 22 and the mounting plate 21 to move together along the Y-axis direction.

[0049] The fixed part of the main valve X-direction drive mechanism 27 is mounted on the X-direction platform 26, and the Y-direction platform 24 is mounted on the moving part of the main valve X-direction drive mechanism 27. The main valve X-direction drive mechanism 27 is used to drive the Y-direction platform 24, the main valve Y-direction drive mechanism 25, the cantilever 23, the main valve Z-direction drive mechanism 22, and the mounting plate 21 to move together along the X-axis direction.

[0050] The X-axis platform 26 is the fixing part of the main valve moving device 20, and the X-axis platform 26 is mounted on the frame 10. The mounting plate 21 is the moving part of the main valve moving device 20, and the fixing parts of the main dispensing module 30 and the auxiliary valve moving device 40 are both mounted on the mounting plate 21.

[0051] The main valve moving device 20 is used to drive the main dispensing module 30 and the fixed part of the auxiliary valve moving device 40 to move together in the XYZ directions, and move along the preset main dispensing path to dispense adhesive to the dispensing point corresponding to the main dispensing module 30.

[0052] Specifically, during the movement of the main dispensing module 30, the secondary valve moving device 40 corrects errors and drives the secondary dispensing module 50 to move along a preset secondary dispensing path to dispense adhesive onto the corresponding dispensing points. The main and secondary dispensing paths are determined primarily by the consistency of the substrate, depending on different operating conditions, and can be operated asynchronously or synchronously, greatly improving efficiency. When the main and secondary dispensing paths are the same, it is a synchronous operation; when they are different, it is an asynchronous operation. The dual-valve asynchronous dispensing machine in this embodiment can operate asynchronously and is also compatible with synchronous operation. For example, the main dispensing path can be triangular, the secondary dispensing path can be square, or the main dispensing path can move from high to low, and the secondary dispensing path can move from low to high.

[0053] like Figure 3 , Figures 7 to 12 As shown, where Figure 3 and Figure 12 The dashed lines in the diagram are connection lines for assembly; assemble according to the direction of the dashed lines. In this embodiment, the secondary valve moving device 40 includes a secondary valve fixing plate 41, a secondary valve X bending plate 42, a secondary valve Y bending plate 43, and a secondary valve Z straight plate 44. The auxiliary valve X bending plate 42 and the auxiliary valve Y bending plate 43 are installed together vertically along the Z-axis. The auxiliary valve fixing plate 41 and the auxiliary valve Z straight plate 44 are respectively installed on the side of the auxiliary valve X bending plate 42 and the auxiliary valve Y bending plate 43 in the same direction. The auxiliary valve fixing plate 41 is located above the auxiliary valve Z straight plate 44 along the Z-axis.

[0054] Specifically, a secondary valve fixing plate 41 is fixed on the secondary valve X bending plate 42, and a secondary valve Z straight plate 44 is fixed on the secondary valve Y bending plate 43. The secondary valve fixing plate 41 and the secondary valve Z straight plate 44 are located on the same side of the secondary valve X bending plate 42 and the secondary valve Y bending plate 43.

[0055] Specifically, the secondary valve moving device 40 has a compact structure, making full use of the overlapping space to reduce the space occupied by the secondary valve moving device 40 and also reduce its weight. Due to the small load mass, there is less vibration and faster speed during movement, which has the advantages of high speed and high precision.

[0056] In this embodiment, the auxiliary valve fixing plate 41 is the fixing part of the auxiliary valve moving device 40, and the auxiliary valve Z straight plate 44 is the moving part of the auxiliary valve moving device 40.

[0057] Specifically, the auxiliary valve fixing plate 41 is fixedly connected to the mounting plate 21 as the fixing part of the auxiliary valve moving device 40. Thus, when the main valve moving device 20 drives the mounting plate 21 and the main dispensing module 30 to move in the XYZ directions, the auxiliary valve moving device 40 and the auxiliary dispensing module 50 will move synchronously. When segments of the main dispensing path and the auxiliary dispensing path are identical, it is equivalent to the auxiliary dispensing module 50 being driven by both the main valve moving device 20 and the auxiliary valve moving device 40 simultaneously, resulting in faster speeds.

[0058] In this embodiment, the two ends of the auxiliary valve fixing plate 41 are arranged horizontally above the moving part of the main valve moving device 20 and above the auxiliary valve Z plate 44.

[0059] For details, please refer to Figure 3 , Figure 4 and Figure 6 , Figure 4 The dashed lines in the diagram represent assembly connection lines; assemble according to the direction of the dashed lines. The main dispensing module 30 and the auxiliary dispensing module 50 are arranged side by side in the X-axis direction. This is because the production line generally flows along the X-axis direction, and the two dispensing positions move along the X-axis direction on the production line. Therefore, arranging the main dispensing module 30 and the auxiliary dispensing module 50 side by side in the X-axis direction allows for simultaneous dispensing at both dispensing positions.

[0060] Combination Figure 3 and Figure 4Furthermore, the auxiliary valve moving device 40 is positioned to rest against the side of the cantilever 23, minimizing the length of the long side of the auxiliary valve fixing plate 41 in the X-axis direction, reducing wobbling caused by the lever principle, and improving accuracy and speed. The auxiliary valve fixing plate 41 is fixedly connected to the end face of the mounting plate 21 in the Y-axis direction, and the auxiliary valve X-axis moving assembly 49 is positioned above the mounting plate 21, further reducing the space occupied. Figure 3 The lower left corner of the auxiliary valve fixing plate 41 has two mounting holes for assembly with the corresponding holes in the upper right corner of the mounting plate 21 to achieve a fixed connection.

[0061] like Figures 7 to 12 As shown, in this embodiment, both the auxiliary valve X bending plate 42 and the auxiliary valve Y bending plate 43 are L-shaped bending plates including mutually perpendicular vertical plates and bottom plates. The bottom plates of the auxiliary valve X bending plate 42 and the auxiliary valve Y bending plate 43 are slidably mounted together. The vertical plates of the auxiliary valve X bending plate 42 and the auxiliary valve Y bending plate 43 are parallel and arranged in the same lateral direction.

[0062] like Figure 12 As shown, in this embodiment, the secondary valve moving device 40 further includes a first guide rail 45, which is a cross roller guide rail. The first guide rail 45 is disposed between the secondary valve X bending plate 42 and the secondary valve Y bending plate 43, and the sliding direction of the first guide rail 45 is parallel to the Y-axis direction.

[0063] Specifically, the fixed part of the first guide rail 45 is fixedly connected to the top of the secondary valve Y-bent plate 43 (i.e., the side with the bottom plate facing upward), and the sliding part of the first guide rail 45 is fixedly connected to the bottom of the secondary valve X-bent plate 42 (i.e., the side with the bottom plate facing downward). This allows the secondary valve X-bent plate 42 and the secondary valve Y-bent plate 43 to move relative to each other along the Y-axis.

[0064] In this embodiment, the auxiliary valve fixing plate 41 is slidably mounted on the upright plate of the auxiliary valve X bending plate 42, and the auxiliary valve Z straight plate 44 is slidably mounted on the upright plate of the auxiliary valve Y bending plate 43.

[0065] In this embodiment, the secondary valve moving device 40 further includes a second guide rail 46, which is a cross roller guide rail. The second guide rail 46 is disposed between the secondary valve Z straight plate 44 and the secondary valve Y bent plate 43, and the sliding direction of the second guide rail 46 is parallel to the Z-axis direction.

[0066] Specifically, the fixed part of the second guide rail 46 is fixedly connected to the side of the auxiliary valve Y-bent plate 43 (i.e., the side of the upright plate facing outwards), and the sliding part of the second guide rail 46 is fixedly connected to the side of the auxiliary valve Z-straight plate 44 (i.e., the side facing the auxiliary valve Y-bent plate 43). This allows the auxiliary valve Z-straight plate 44 and the auxiliary valve Y-bent plate 43 to move relative to each other along the Z-axis.

[0067] In this embodiment, the bottom plates of the secondary valve X bending plate 42 and the secondary valve Y bending plate 43 are both set to be parallel to the XY plane, and the vertical plates of the secondary valve X bending plate 42 and the secondary valve Y bending plate 43 are both set to be parallel to the ZX plane.

[0068] In this embodiment, both the auxiliary valve fixing plate 41 and the auxiliary valve Z plate 44 are configured to be parallel to the ZX plane.

[0069] In this embodiment, the auxiliary valve fixing plate 41 is a rectangular plate, and the long side of the auxiliary valve fixing plate 41 is set to the X-axis direction.

[0070] like Figure 3 As shown, in this embodiment, the secondary valve moving device 40 further includes a secondary valve X-direction moving assembly 49, a secondary valve Y-direction moving assembly 48, and a secondary valve Z-direction moving assembly 47; The fixed part of the auxiliary valve X-direction moving assembly 49 is fixedly connected to the auxiliary valve fixed straight plate 41, and the moving part of the auxiliary valve X-direction moving assembly 49 is fixedly connected to the auxiliary valve X-bending plate 42. The auxiliary valve X-direction moving assembly 49 is used to drive the auxiliary valve X-bending plate 42 to move relative to the auxiliary valve fixed straight plate 41 in the X direction. The fixed part of the auxiliary valve Y-direction moving assembly 48 is fixedly connected to the auxiliary valve X-bending plate 42, and the moving part of the auxiliary valve Y-direction moving assembly 48 is fixedly connected to the auxiliary valve Y-bending plate 43. The auxiliary valve Y-direction moving assembly 48 is used to drive the auxiliary valve Y-bending plate 43 to move relative to the auxiliary valve X-bending plate 42 in the Y direction. The fixed part of the auxiliary valve Z-direction moving assembly 47 is fixedly connected to the auxiliary valve Y-bent plate 43, and the moving part of the auxiliary valve Z-direction moving assembly 47 is fixedly connected to the auxiliary valve Z-straight plate 44. The auxiliary valve Z-direction moving assembly 47 is used to drive the auxiliary valve Z-straight plate 44 to move relative to the auxiliary valve Y-bent plate 43 in the Z direction.

[0071] Specifically, the inner side of the bending direction of the X-bend plate 42 of the secondary valve forms an open receiving space to accommodate the Y-direction moving assembly 48 of the secondary valve, and the inner side of the bending direction of the Y-bend plate 43 of the secondary valve forms an open receiving space to accommodate the Z-direction moving assembly 47 of the secondary valve. This further reduces the equipment space occupied by the secondary valve moving device 40 and reduces its weight, further improving the accuracy and speed during the movement process.

[0072] The auxiliary valve fixing plate 41 is a rectangular plate, and the long side of the auxiliary valve fixing plate 41 is set in the X-axis direction. The moving direction of the moving part of the auxiliary valve X-axis moving assembly 49 is also in the X-axis direction. By mounting the auxiliary valve X-axis moving assembly 49 on the auxiliary valve fixing plate 41, the thickness of the auxiliary valve moving device 40 in the Y-axis direction can be reduced.

[0073] In this embodiment, the secondary valve Z-direction moving assembly 47 is used to drive the secondary valve Z-straight plate 44 and the secondary dispensing module 50 on the secondary valve Z-straight plate 44 to move together along the Z-direction; The auxiliary valve Y-direction moving assembly 48 is used to drive the auxiliary valve Y-direction bending plate 43, the auxiliary valve Z-direction moving assembly 47, the auxiliary valve Z-direction straight plate 44 and the auxiliary dispensing module 50 to move together along the Y direction; like Figure 3 As shown, the auxiliary valve X-direction moving assembly 49 is used to drive the auxiliary valve X-direction bending plate 42, the auxiliary valve Y-direction moving assembly 48, the auxiliary valve Y-direction bending plate 43, the auxiliary valve Z-direction moving assembly 47, the auxiliary valve Z-direction straight plate 44, and the auxiliary dispensing module 50 to move together along the X-direction.

[0074] like Figure 12 As shown, in this embodiment, the secondary valve Z-direction moving assembly 47 includes a secondary valve Z-direction driving mechanism 471. The secondary valve Y-bent plate 43 is provided with a first through groove 431 that penetrates the side plate wall of the secondary valve Z-straight plate 44. The fixed part of the secondary valve Z-direction driving mechanism 471 is located on the inside of the bend of the side plate wall of the secondary valve Y-bent plate 43. The moving part of the secondary valve Z-direction driving mechanism 471 passes through the first through groove 431 and connects to the secondary valve Z-straight plate 44.

[0075] Specifically, the first through groove 431 extends along the Z-axis and is a rectangular groove. The travel of the secondary valve Z-plate 44 in the Z-axis direction is related to the length of the first through groove 431 in the Z-axis direction. The first through groove 431 and the second guide rail 46 together restrict the secondary valve Z-plate 44 to move only along the Z-axis direction.

[0076] In this embodiment, the secondary valve Z-direction moving assembly 47 further includes a first connector 472. One end of the first connector 472 is fixedly connected to the moving part of the secondary valve Z-direction driving mechanism 471, and the other end passes through the first through groove 431 and is fixedly connected to the secondary valve Z-direction plate 44.

[0077] like Figure 8 As shown, in this embodiment, the secondary valve Y-direction moving assembly 48 includes a secondary valve Y-direction driving mechanism 481. A second through groove 421 is provided on the side plate wall of the secondary valve X-bending plate 42 that abuts against the secondary valve Y-bending plate 43. The fixing part of the secondary valve Y-direction driving mechanism 481 is located on the inner side of the bend of the side plate wall of the secondary valve X-bending plate 42. The moving part of the secondary valve Y-direction driving mechanism 481 passes through the second through groove 421 and connects to the secondary valve Y-bending plate 43.

[0078] Specifically, the second through groove 421 extends along the Y-axis and is a rectangular groove. The stroke of the auxiliary valve Y-bend plate 43 in the Y-axis direction is related to the length of the second through groove 421 in the Y-axis direction. The second through groove 421 and the first guide rail 45 together restrict the auxiliary valve Y-bend plate 43 to move only along the Y-axis direction.

[0079] In this embodiment, the secondary valve Y-direction moving assembly 48 further includes a second connector 482. One end of the second connector 482 is fixedly connected to the moving part of the secondary valve Y-direction driving mechanism 481, and the other end passes through the second through groove 421 and is fixedly connected to the secondary valve Y-direction bending plate 43.

[0080] In this embodiment, the secondary valve X-direction moving assembly 49 includes a secondary valve X-direction drive motor 491, a transmission mechanism 492, and a spring plate 493; The auxiliary valve X-direction drive motor 491 is fixedly connected to the auxiliary valve fixed plate 41, and the transmission mechanism 492 is connected to the auxiliary valve X-direction drive motor 491 for transmission, which is used to convert the rotation of the auxiliary valve X-direction drive motor 491 into movement along the X direction. The spring plate 493 is configured to be parallel to the side of the auxiliary valve fixing plate 41 and the auxiliary valve X bending plate 42, and the two ends of the spring plate 493 are fixedly connected to the transmission mechanism 492 and the auxiliary valve X bending plate 42 respectively.

[0081] In this embodiment, the sides of the spring plate 493, the auxiliary valve fixing plate 41, and the auxiliary valve X bending plate 42 are all parallel to the ZX plane. After being subjected to force, the spring plate 493 swings and twists along the Y-axis direction to correct the radial error of the sides of the auxiliary valve fixing plate 41 and the auxiliary valve X bending plate 42 in the Y-axis direction.

[0082] In this embodiment, the auxiliary valve X-direction moving assembly 49 further includes a third guide rail 494, which is a linear guide rail. The third guide rail 494 is disposed between the auxiliary valve X-bending plate 42 and the auxiliary valve fixed straight plate 41. The sliding direction of the third guide rail 494 is parallel to the X-axis direction. The fixed part of the third guide rail 494 is fixedly connected to the auxiliary valve fixed plate 41, and the movable part of the third guide rail 494 is fixedly connected to the side of the spring piece 493 and the auxiliary valve X bending plate 42.

[0083] like Figure 12 As shown, in this embodiment, the transmission mechanism 492 includes a coupling 4921, a lead screw 4922, a nut seat 4923, and a third connecting member 4924. The two ends of the coupling 4921 are fixedly connected to the auxiliary valve X-direction drive motor 491 and the lead screw 4922, respectively, and the nut seat 4923 is slidably mounted on the lead screw 4922. One end of the third connector 4924 is fixedly connected to the nut seat 4923, and the other end is fixedly connected to the spring piece 493.

[0084] For details, see Figure 12The auxiliary valve X-axis drive motor 491 is fixedly connected to the side of the auxiliary valve fixed plate 41. The lead screw 4922 passes through the opening in the side. When the lead screw 4922 rotates, the nut seat 4923 moves along the X-axis on the lead screw 4922. The movement of the nut seat 4923 is transmitted to the auxiliary valve X-axis bending plate 42 through the moving parts of the third connecting member 4924, the spring piece 493, and the third guide rail 494 in sequence. Therefore, the auxiliary valve X-axis bending plate 42 moves along the X-axis under the restriction of the third guide rail 494.

[0085] In this embodiment, both the main dispensing module 30 and the auxiliary dispensing module 50 include one or more of a screw valve, a dispensing needle, and a piezoelectric valve. The moving part of the main valve moving device 20 and / or the moving part of the auxiliary valve moving device 40 are also provided with one or more of a sensor, a UV curing lamp, and a visual inspection device.

[0086] The specific visual inspection device is an optical component used for positioning before dispensing and inspection after dispensing, further ensuring the accuracy of the dispensing operation.

[0087] Specifically, multiple main valve moving devices 20 can be configured on the dispensing machine, and these multiple main valve moving devices 20 share the same X-axis platform 26. Each main valve moving device 20 can also be equipped with a corresponding auxiliary valve moving device 40, a main dispensing module 30, and an auxiliary dispensing module 50 for assembly line operation. For example, see reference... Figure 1 The dispensing machine is equipped with two main valve moving devices 20, totaling two main dispensing modules 30 and two auxiliary dispensing modules 50, which together dispense adhesive to multiple dispensing points on the production line.

[0088] Specifically, the equipment offers flexible functional combinations. The main dispensing module 30 and the auxiliary dispensing module 50 are also compatible with screw valves, traditional needle dispensing, piezoelectric valves, various sensors, UV curing lamps, and various vision inspection devices, allowing for flexible functional combinations. For example, dispensing at dispensing position 1 can be followed by curing at dispensing position 2, or dispensing at dispensing position 1 can be followed by screw valve at dispensing position 2 and piezoelectric valve at dispensing position 2, or dispensing at dispensing position 1 can be followed by detection at dispensing position 2.

[0089] The working principle and steps of the asynchronous operation of the dual-valve asynchronous dispensing machine in this embodiment are explained below: 1. The calibration module on the mounting plate 21 selects three points on the substrate on the production line to determine the adhesive application surface (generally parallel to the XY plane, but can also be inclined or irregular curved surface, etc.).

[0090] 2. Calculate the main dispensing path and the secondary dispensing path, calculate the difference between the secondary dispensing path and the main dispensing path in the XYZ directions, and plan the movement of the main valve moving device 20 and the secondary valve moving device.

[0091] 3. The height measurement module on the mounting plate 21 performs laser height measurement and correction on the substrates on the production line.

[0092] 4. The main valve moving device 20 drives the main dispensing module 30 to dispense glue along the main dispensing path at the main dispensing position. At the same time, the auxiliary valve moving device 40 overcomes the difference and drives the auxiliary dispensing module 50 to dispense glue along the auxiliary dispensing path at the auxiliary dispensing position.

[0093] 5. After the dispensing operation is completed, the vision inspection device on the mounting plate 21 inspects the dispensing status on the substrate.

[0094] Specifically, for example, if the main dispensing path is I and the secondary dispensing path is L, with the overlapping path segment being the portion of I, then firstly, the main valve moving device 20 and the secondary valve moving device 40 drive the main dispensing module 30 and the secondary dispensing module 50 to the starting position. The main valve moving device 20 drives the main dispensing module 30 to move linearly along path I. At this time, the secondary valve moving device 40 does not work initially, which is equivalent to the main valve moving device 20 driving the main dispensing module 30 and the secondary dispensing module 50 to complete the same segment I together. Then, the secondary valve moving device 40 independently controls the secondary valve dispensing module to complete the remaining segment of path L, while the main valve moving device 20 does not work. This is equivalent to the secondary valve moving device 40 driving the secondary valve dispensing module to move the remaining path segment relative to the mounting plate 21.

[0095] In summary, this embodiment of the invention allows the auxiliary valve moving device 40 and the auxiliary dispensing module 50 to be installed on the main valve moving device 20. The two dispensing modules can move along different asynchronous dispensing paths, offering advantages such as small equipment footprint and high operational efficiency. During the movement of the main dispensing module 30 and the auxiliary dispensing module 50, some dispensing paths overlap. The auxiliary dispensing module 50 is simultaneously driven by both the main valve moving device 20 and the auxiliary valve moving device 40, resulting in even faster speed.

[0096] Furthermore, the auxiliary valve moving device 40 includes an auxiliary valve fixed straight plate 41, an auxiliary valve X-bending plate 42, an auxiliary valve Y-bending plate 43, and an auxiliary valve Z-straight plate 44. The auxiliary valve X-bending plate 42 and the auxiliary valve Y-bending plate 43 are mounted vertically together along the Z-axis. The auxiliary valve fixed straight plate 41 and the auxiliary valve Z-straight plate 44 are respectively mounted on the sides of the auxiliary valve X-bending plate 42 and the auxiliary valve Y-bending plate 43 in the same direction. The auxiliary valve fixed straight plate 41 is positioned above the auxiliary valve Z-straight plate 44 along the Z-axis. The auxiliary valve fixed straight plate 41, the auxiliary valve X-bending plate 42, the auxiliary valve Y-bending plate 43, and the auxiliary valve Z-straight plate 44 are stacked as four modular designs in a cubic shape, resulting in a compact structure. This reduces the weight of the auxiliary valve moving device 40, increases the moving speed of the main valve moving device 20 driving the auxiliary dispensing module 50, reduces accuracy errors caused by jitter during heavy-mass movement, and also reduces the space occupied by the auxiliary valve moving device 40, increasing the moving stroke of the main valve moving device 20.

[0097] Furthermore, the two ends of the auxiliary valve fixing plate 41 are horizontally positioned above the moving part of the main valve moving device 20 and above the auxiliary valve Z-plate 44. The main dispensing module 30 and the auxiliary dispensing module 50 are arranged side by side on the moving part of the main valve moving device 20 and the auxiliary valve Z-plate 44. The area below the main dispensing module 30 and the auxiliary dispensing module 50 is two dispensing positions. Driven by the main valve moving device 20 and the auxiliary valve moving device 40, the two dispensing modules asynchronously dispense glue to the two dispensing positions.

[0098] Furthermore, both the auxiliary valve X bending plate 42 and the auxiliary valve Y bending plate 43 are L-shaped bending plates. The auxiliary valve Y-direction moving assembly 48 and the auxiliary valve Z-direction moving assembly 47 are respectively located on the inner side of the bending of the auxiliary valve X bending plate 42 and the auxiliary valve Y bending plate 43, maximizing the use of the space occupied by the two bending plates. This further reduces the space volume occupied by the auxiliary valve moving device 40.

[0099] Furthermore, the secondary valve X-direction moving assembly 49 includes a secondary valve X-direction drive motor 491, a transmission mechanism 492, and a spring plate 493. The spring plate 493 is configured to be parallel to the sides of the secondary valve fixing plate 41 and the secondary valve X-bending plate 42. Both ends of the spring plate 493 are fixedly connected to the transmission mechanism 492 and the secondary valve X-bending plate 42, respectively. The spring plate 493 is an elastic connecting component, reducing radial errors caused by the machining or assembly of structural components and improving the smoothness of the mechanism. When the secondary valve fixing plate 41 and the secondary valve X-bending plate 42 are assembled, they are installed along the Y-axis direction. Therefore, there are assembly or machining errors between the secondary valve fixing plate 41 and the secondary valve X-bending plate 42 in the Y-direction. The spring plate 493 can be bent along the Y-direction to offset this error. Moreover, the movement direction of the spring plate 493 is the X-axis direction, and the bending of the spring plate 493 does not affect the transmission effect.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
