Description
Technical Field
[0001] This utility model relates to the field of mobile device technology, and in particular to a cantilever mobile device and a dispensing machine. Background Technology
[0002] A dispensing machine is a machine that uses a piezoelectric valve or dispensing needle to dispense adhesive. It requires moving the piezoelectric valve or dispensing needle in the XYZ directions to dispense adhesive.
[0003] Existing dispensing machines use a gantry-type moving device to move the piezoelectric valve or dispensing needle. Each direction requires a lead screw (beam), driving end, and driven end. Inconsistent precision between the driving and driven ends, and the movement of the heavy beam causing machine vibration, all affect accuracy. The length of the lead screw (beam) is equal to the stroke length, and the distance between the driving and driven ends is very long. This makes it easy for errors to occur during movement, resulting in low precision, large vibration, and a complex structure that leads to high weight and slow movement speed.
[0004] Under the above circumstances, there is an urgent need for a conveying device and dispensing machine with high precision, low vibration, short stroke, and light weight. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a cantilever moving device, which can shorten the length of the cantilever, Z-axis moving component and mounting plate in the Y-axis direction by fixing the Z-axis driving mechanism inside the cantilever. The torque of the mounting plate on the cantilever is shorter, which has the advantages of high precision, low vibration, short stroke and light weight.
[0006] This utility model provides a cantilever moving device, including a frame, an XY plane moving component mounted on the frame, a cantilever mounted on the XY plane moving component, a Z-axis moving component, and a mounting plate; The Z-axis moving component includes a Z-axis driving mechanism. The cantilever is hollow inside and has a through groove on its side wall that extends into the interior. The fixed part of the Z-axis driving mechanism is located inside the cantilever, and the moving part of the Z-axis driving mechanism passes through the through groove and connects to the mounting plate. The Z-axis moving component is used to drive the mounting plate to move relative to the cantilever along the Z-axis direction. The XY plane moving component is used to drive the cantilever, the Z-axis moving component, and the mounting plate to move together in the XY plane.
[0007] Furthermore, the through groove is formed on the end side wall surface of the cantilever in the Y-axis direction.
[0008] Furthermore, the Z-axis moving component also includes a first connector, one end of which is fixedly connected to the moving part of the Z-axis driving mechanism, and the other end passes through the through groove and is fixedly connected to the mounting plate.
[0009] Furthermore, the Z-axis moving component also includes a Z-axis slide and a Z-axis guide rail; The Z-axis guide rail extends along the Z-axis direction and is fixedly installed on the side wall of the cantilever. The Z-axis slide block is slidably mounted on the Z-axis guide rail. The mounting plate is fixedly connected to the Z-axis slide block. The Z-axis drive mechanism is used to drive the mounting plate, the first connector and the Z-axis slide to move together along the Z-axis direction on the Z-axis guide rail.
[0010] Furthermore, the Z-axis height of the cantilever at one end with the mounting plate is greater than the Z-axis height at the other end, and the Z-axis height gradually decreases from the end with the mounting plate to the other end.
[0011] Furthermore, the long side of the cantilever is configured to extend along the Y-axis, the side of the cantilever is trapezoidal, and the top surface of the cantilever is an inclined surface.
[0012] Furthermore, when the cantilever moves on the XY plane moving assembly, the mounting plate always remains above the Z-direction projection boundary of the XY plane moving assembly and is suspended in the air, with the working area located below the mounting plate.
[0013] Furthermore, the XY plane moving component includes an X-axis platform, an X-axis slide, a Y-axis platform, and a Y-axis slide; The X-axis platform is mounted on the frame, and the long side of the X-axis platform is configured to extend along the X-axis direction. The X-axis slide is mounted on the X-axis platform and moves linearly along the X-axis direction. The Y-axis platform is mounted on the X-axis slide block, the long side of the Y-axis platform is configured to extend along the Y-axis direction, and the Y-axis slide block is mounted on the Y-axis platform and moves linearly along the Y-axis direction; The end of the cantilever away from the mounting plate is mounted on the Y-axis slide block, and the mounting plate is always kept outside the Z-axis projection boundary of the X-axis platform and the Y-axis platform and suspended in the air.
[0014] Furthermore, a portion of the Y-axis platform is fixedly mounted on the X-axis slide, and the boundaries of the Y-axis platform and the X-axis slide are flush on one side in the Y-axis direction. The other portion of the Y-axis platform extends out of the other side boundary of the X-axis slide along the Y-axis direction and is suspended in the air.
[0015] Furthermore, the mounting plate is disposed at one end of the cantilever away from the suspended portion of the Y-axis platform.
[0016] Furthermore, the XY plane moving component also includes a Y-axis driving mechanism, which is fixedly connected to the Y-axis platform and is used to drive the cantilever to move along the Y-axis direction on the Y-axis platform.
[0017] Furthermore, the width of the X-axis slide in the X-axis direction is equal to the combined width of the Y-axis drive mechanism and the cantilever in the X-axis direction.
[0018] Furthermore, the travel of the cantilever in the Y-axis direction is the length of the Y-axis platform in the Y-axis direction minus the length of the Y-axis slide in the Y-axis direction.
[0019] Furthermore, the travel of the cantilever in the X-axis direction is the length of the X-axis platform in the X-axis direction minus the length of the X-axis slide in the X-axis direction.
[0020] This utility model also provides a dispensing machine, including a working module and a cantilever moving device as described in any of the above claims. The working module is fixedly connected to the mounting plate. The working module includes one or more of the following: a screw valve, a dispensing needle, a piezoelectric valve, a sensor, a UV curing lamp, and a vision inspection device.
[0021] In summary, by fixing the Z-axis drive mechanism inside the cantilever, the length of the cantilever, Z-axis moving component, and mounting plate in the Y-axis direction is shortened, and the torque of the mounting plate on the cantilever is shorter, resulting in advantages such as high precision, low vibration, short stroke, and light weight.
[0022] Furthermore, the top surface of the cantilever is inclined, and the Z-axis height of the end of the cantilever with the mounting plate is greater than that of the other end, with the Z-axis height gradually decreasing from the end with the mounting plate to the other end. This reduces the mass of the cantilever without affecting operation, while also improving its tensile strength and allowing for faster cantilever movement.
[0023] Furthermore, the width of the X-axis slide in the X-axis direction is equal to the combined width of the Y-axis drive mechanism and the cantilever in the X-axis direction. The XY plane moving component has a compact structure, which is different from the gantry shape of traditional cabinet-type dispensing machines. It solves the problems of inconsistent accuracy between the master and slave ends and machine vibration caused by the movement of a large mass crossbeam in gantry dispensing machines, thus affecting accuracy. Since this application has no slave end, the load mass is small, and it has the advantages of high speed and high precision.
[0024] Furthermore, multiple operation modules can be installed on the dispensing machine, allowing for flexible combinations of equipment functions. Attached Figure Description

[0041] 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.
[0042] The following detailed explanation uses specific examples: like Figures 1 to 10 As shown, this utility model embodiment provides a cantilever moving device, including a frame 10, an XY plane moving component 20 mounted on the frame 10, a cantilever 30 mounted on the XY plane moving component 20, a Z-axis moving component 40 and a mounting plate 50. like Figure 2As shown, the Z-axis moving assembly 40 includes a Z-axis driving mechanism 41. The cantilever 30 is hollow inside and has a through groove 31 extending into the interior on its side wall. The fixed part of the Z-axis driving mechanism 41 is located inside the cantilever 30, and the moving part of the Z-axis driving mechanism 41 passes through the through groove and connects to the mounting plate 50. The Z-axis moving assembly 40 is used to drive the mounting plate 50 to move relative to the cantilever 30 along the Z-axis direction. Specifically, the Z-axis drive mechanism 41 includes a Z-axis motor 411, a lead screw 412, and a nut seat 413. The rotation shaft of the Z-axis motor 411 is coaxially connected to the lead screw 412, and the nut seat 413 is connected to the lead screw 412. The first connecting member 42 is fixed on the nut seat 413. The moving part of the Z-axis drive mechanism 41 is the nut seat 413.
[0043] like Figure 1 As shown, the cantilever 30 is mounted on the XY plane moving assembly 20, which is mounted on the frame 10. The XY plane moving assembly 20 is used to drive the cantilever 30, the Z-axis moving assembly 40, and the mounting plate 50 to move together in the XY plane.
[0044] Specifically, the Z-axis motor 411 is a servo motor, and the moving direction of the moving part nut seat 413 is set in the Z-axis direction. One end of the first connecting member 42 is annularly sleeved on the nut seat 413, and the other end has a flat surface that is fixedly connected to the mounting plate 50. When the nut seat 413 moves up and down along the Z-axis, the first connecting member 42 and the mounting plate 50 move synchronously together.
[0045] Specifically, the mounting plate 50 is used to install the working module 60, which is a piezoelectric valve or a dispensing needle, etc., for applying glue.
[0046] Specifically, the through groove 31 is oriented along the Y-axis and is located on the end face of the cantilever 30. The through groove 31 extends along the Z-axis, and its length is greater than or equal to the stroke of the first connector 42.
[0047] In this embodiment, the through groove 31 is formed on the end side wall surface of the cantilever 30 in the Y-axis direction.
[0048] In this embodiment, the Z-axis moving component 40 further includes a first connector 42, one end of which is fixedly connected to the moving part of the Z-axis driving mechanism 41, and the other end passes through the through groove 31 and is fixedly connected to the mounting plate 50.
[0049] In this embodiment, the first connector 42 passes through the through slot 31 of the cantilever 30 along the Y-axis direction.
[0050] In this embodiment, the moving part of the Z-axis drive mechanism 41, the first connecting member 42, and the mounting plate 50 move synchronously along the Z-axis direction.
[0051] In this embodiment, the Z-axis moving component 40 further includes a Z-axis slide 43 and a Z-axis guide rail 44; Z-axis guide rail 44 extends along the Z-axis direction and is fixedly installed on the side wall of cantilever 30. Z-axis slide block 43 is slidably mounted on Z-axis guide rail 44. Mounting plate 50 is fixedly connected to Z-axis slide block 43. Z-axis drive mechanism 41 is used to drive mounting plate 50, first connector 42 and Z-axis slide 43 to move together on Z-axis guide rail 44 along the Z-axis direction.
[0052] Specifically, there are two sets of Z-axis slide block 43 and Z-axis guide rail 44, which are respectively set on both sides of the through groove 31 to ensure that the movement of the mounting plate 50 is stable and does not shake, thereby improving accuracy and reducing vibration.
[0053] In this embodiment, the Z-axis height of the cantilever 30 at one end with the mounting plate 50 is greater than the Z-axis height at the other end, and the Z-axis height gradually decreases from the end with the mounting plate 50 to the other end.
[0054] In this embodiment, the long side of the cantilever 30 is set to extend along the Y-axis direction, the side of the cantilever 30 is trapezoidal, and the top surface of the cantilever 30 is inclined.
[0055] Specifically, the cantilever 30 is used to suspend and support the mounting plate 50. The interior of the cantilever 30 is hollowed out to reduce weight, and it also has internal reinforcing ribs to improve structural strength. The reinforcing ribs extend in the X-axis direction. The height of the end of the cantilever 30 where the mounting plate 50 is mounted is greater than the height of the other end. Since the working module 60 and the Z-axis moving component 40 are also mounted on the mounting plate 50, the height is increased to accommodate the Z-axis movement stroke of the mounting plate 50. The height of this end of the cantilever 30 is greater than or equal to the Z-axis movement stroke of the mounting plate 50. Furthermore, the inclined design of the cantilever 30 reduces weight. With reduced weight, the cantilever 30 can move faster, with higher precision and less vibration in the XY plane.
[0056] Specifically, the cantilever 30 has a mounting plate 50 at one end as the main load-bearing end. A higher Z-axis height can improve structural strength and load-bearing capacity. Moreover, the Z-axis stroke of the mounting plate 50 is also related to the Z-axis height of the cantilever 30. A higher Z-axis height can achieve a longer Z-axis stroke of the mounting plate 50.
[0057] like Figure 3 As shown, in this embodiment, when the cantilever 30 moves on the XY plane moving component 20, the mounting plate 50 always remains above the Z-direction projection boundary of the XY plane moving component 20 and is suspended in the air, with the working area below the mounting plate 50.
[0058] Specifically, the work area includes areas such as dispensing adhesive.
[0059] like Figures 3 to 10As shown, in this embodiment, the XY plane moving component 20 includes an X-axis platform 21, an X-axis slide 22, a Y-axis platform 23, and a Y-axis slide 24; Combination Figure 1 and Figure 8 The X-axis platform 21 is mounted on the frame 10, and the long side of the X-axis platform 21 is set to extend along the X-axis direction. The X-axis slide 22 is mounted on the X-axis platform 21 and moves linearly along the X-axis direction. like Figure 8 As shown, the Y-axis platform 23 is mounted on the X-axis slide 22, and the long side of the Y-axis platform 23 is set to extend along the Y-axis direction. The Y-axis slide 24 is mounted on the Y-axis platform 23 and moves linearly along the Y-axis direction. The end of the cantilever 30 away from the mounting plate 50 is mounted on the Y-axis slide 24, and the mounting plate 50 is always kept outside the Z-axis projection boundary of the X-axis platform 21 and the Y-axis platform 23 and suspended in the air.
[0060] Specifically, the Y-axis platform 23 and the X-axis platform 21 are both rectangular in shape, while the Y-axis slide 24 and the X-axis slide 22 are both square in shape.
[0061] Specifically, the travel distance of the cantilever 30 in the Y direction is less than or equal to the Y length of the Y-direction platform 23. When the length of the cantilever 30 extending beyond the Y-direction platform 23 is at its minimum, the mounting plate 50 also extends beyond the Y-direction platform 23 and remains suspended.
[0062] In this embodiment, a portion of the Y-axis platform 23 is fixedly mounted on the X-axis slide 22, and the boundaries of the Y-axis platform 23 and the X-axis slide 22 are flush on one side in the Y-axis direction. The other portion of the Y-axis platform 23 extends out of the other side boundary of the X-axis slide 22 along the Y-axis direction and is suspended in the air.
[0063] In this embodiment, the mounting plate 50 is disposed at one end of the cantilever 30 away from the suspended portion of the Y-axis platform 23, which is used to maintain balance.
[0064] Specifically, when the cantilever 30 extends the Y-axis platform 23 to its maximum length, the suspended part of the Y-axis platform 23 can play a balancing role, preventing swaying due to changes in the center of gravity.
[0065] like Figure 4 As shown, in this embodiment, the XY plane moving component 20 further includes a Y-axis driving mechanism 25, which is fixedly connected to the Y-axis platform 23. The Y-axis driving mechanism 25 is used to drive the cantilever 30 to move along the Y-axis direction on the Y-axis platform 23.
[0066] In this embodiment, the width of the X-axis slide 22 in the X-axis direction is equal to the combined width of the Y-axis drive mechanism 25 and the cantilever 30 in the X-axis direction.
[0067] Specifically, such as Figure 4 As shown, the Y-axis drive mechanism 25 is arranged parallel to the Y-axis next to the Y-axis platform 23, and the side of the Y-axis drive mechanism 25 is fixedly connected to the side of the Y-axis platform 23. Figure 8 As shown, the Y-axis drive mechanism 25 and the Y-axis platform 23 are jointly mounted on the X-axis slide 22, and the width of the X-axis slide 22 in the X-axis direction is equal to the combined width of the Y-axis drive mechanism 25 and the cantilever 30 in the X-axis direction.
[0068] In this embodiment, as Figure 4 As shown, the XY plane moving assembly 20 also includes a second connector 26, which is a U-shaped connector. The motor included in the Y-axis drive mechanism 25 is a U-shaped motor. The second connector 26 is fixedly connected to the moving part of the Y-axis drive mechanism 25 and the side of the cantilever 30, respectively. The moving part of the Y-axis drive mechanism 25 moves along the Y-axis direction, and the moving part of the Y-axis drive mechanism 25, the second connector 26, and the cantilever 30 move together on the Y-axis platform 23 along the Y-axis direction.
[0069] like Figure 3 As shown, in this embodiment, the XY plane moving component 20 also includes a Y guide rail 29; Y-axis guide rail 29 extends along the Y-axis direction and is fixedly mounted on Y-axis platform 23. Y-axis slide block 24 is slidably mounted on Y-axis guide rail 29. The bottom of cantilever 30 is fixedly connected to Y-axis slide block 24. Y-axis drive mechanism 25 is used to drive the second connector 26 and cantilever 30 to move together along the Y-axis direction on Y-guide rail 29.
[0070] Specifically, there are two Y-axis guide rails 29 and four Y-axis slide blocks 24. Two Y-axis slide blocks 24 are set on one Y-axis guide rail 29. The two Y-axis guide rails 29 are set parallel to each other on the Y-axis platform 23 to ensure that the movement of the cantilever 30 is stable and does not wobble, thereby improving accuracy and reducing vibration.
[0071] In this embodiment, the travel of the cantilever 30 in the Y-axis direction is the length of the Y-axis platform 23 in the Y-axis direction minus the length of the Y-axis slide 24 in the Y-axis direction.
[0072] In this embodiment, the travel of the cantilever 30 in the X-axis direction is the length of the X-axis platform 21 in the X-axis direction minus the length of the X-axis slide block 22 in the X-axis direction.
[0073] like Figure 8As shown, in this embodiment, the XY plane moving assembly 20 further includes an X-axis driving mechanism 27, which is fixedly connected to the X-axis platform 21. The X-axis driving mechanism 27 drives the Y-axis platform 23 to move along the X-axis direction on the X-axis platform 21. The X-axis driving mechanism 27 is hidden inside the X-axis platform 21, and the bottom of the X-axis slide 22 is fixedly connected to the moving part of the X-axis driving mechanism 27. The motor included in the X-axis driving mechanism 27 is a flat linear motor.
[0074] In this embodiment, the XX-plane moving component further includes an X-guide rail 28; The X-axis guide rail 28 extends along the X-axis direction and is fixedly mounted on the X-axis platform 21. The X-axis slide block 22 is slidably mounted on the X-axis guide rail 28. The bottom of the Y-axis platform 23 is fixedly connected to the X-axis slide block 22. The X-axis drive mechanism 27 is used to drive the X-axis slide 22 and the Y-axis platform 23 to move together along the X-axis direction on the X-axis guide rail 28.
[0075] Specifically, there are two X-axis guide rails 28 and four X-axis slide blocks 22. Two X-axis slide blocks 22 are set on one X-axis guide rail 28. The two X-axis guide rails 28 are set parallel to each other on the X-axis platform 21 to ensure that the movement of the cantilever 30 is stable and does not wobble, thereby improving accuracy and reducing vibration.
[0076] like Figure 1 As shown, this utility model embodiment also provides a dispensing machine, including a working module 60 and a cantilever moving device as described above. The working module 60 is fixedly connected to the mounting plate 50. The working module 60 includes one or more of the following: a screw valve, a dispensing needle, a piezoelectric valve, a sensor, a UV curing lamp, and a vision inspection device.
[0077] The number of specific cantilever mobile devices is at least one, each cantilever mobile device is counted as a workstation, and the number of work modules 60 on each cantilever mobile device is at least one, and the type is at least one.
[0078] Specifically, the cantilever moving device in this embodiment occupies less space than the traditional gantry moving device under the same working conditions. Moreover, the functions of the operation module 60 can be flexibly combined, such as: dispensing at station 1 - curing at station 2, screw valve at station 1 - piezoelectric valve at station 2, dispensing at station 1 - detection at station 2, etc.
[0079] Moreover, the cantilever mobile device in one workstation can be equipped with multiple work modules 60, enabling asynchronous or synchronous operations on the same workstation, which greatly improves work efficiency.
[0080] In summary, by fixing the Z-axis drive mechanism 41 inside the cantilever 30, the overall length of the cantilever 30, the Z-axis moving component 40, and the mounting plate 50 in the Y-axis direction is shortened, and the torque of the mounting plate 50 on the cantilever 30 is shorter, which has the advantages of high precision, low vibration, short stroke, and light weight.
[0081] Furthermore, the top surface of the cantilever 30 is inclined, and the Z-axis height of the end of the cantilever 30 with the mounting plate 50 is greater than the Z-axis height of the other end, with the Z-axis height gradually decreasing from the end with the mounting plate 50 to the other end. This reduces the mass of the cantilever 30 without affecting its operation, while also improving its tensile strength and allowing for faster movement.
[0082] Furthermore, the width of the X-axis slide 22 in the X-axis direction is equal to the width of the Y-axis platform 23 in the X-axis direction, and the combined width of the Y-axis drive mechanism 25 and the cantilever 30 in the X-axis direction is less than or equal to the width of the Y-axis platform 23 in the X-axis direction. The XY plane moving component 20 has a compact structure, which is different from the gantry shape of traditional cabinet-type dispensing machines. It solves the problems of inconsistent accuracy between the master and slave ends and machine vibration caused by the movement of a large mass crossbeam in gantry dispensing machines, thus affecting accuracy. Since this application has no slave end, the load mass is small, and it has the advantages of high speed and high precision. Furthermore, multiple multi-functional modules can be installed on the dispensing machine, allowing for flexible combinations of equipment functions.
[0083] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
