Description

Technical Field

[0001] The present invention relates to the field of printing technology, and particularly to a support base, an adjustment module, and an inkjet printing carriage. Background Art

[0002] Printed circuit board inkjet printing equipment is used to precisely spray ink or solder paste on a circuit board, and the spraying accuracy directly determines the quality of circuit performance. As the core component of the inkjet printing equipment, the installation structure design of the print head is crucial for ensuring the accuracy of the print head. A reasonable installation structure can effectively reduce the influence of mechanical errors and vibrations on the print head.

[0003] To improve the installation and positioning accuracy of the print head, related technologies have proposed an inkjet printer multi-print head combined print head adjustment mechanism. There are glass bead screws, conical adjustment block assembly I, and conical adjustment block assembly II provided on the print head mounting seat. By adjusting the above components, the position of the print head assembly can be flexibly adjusted, improving the installation and positioning accuracy of the print head.

[0004] The above print head adjustment mechanism considers the installation and positioning accuracy of the print head before use, but does not consider that the print head will undergo thermal deformation due to the increase in equipment temperature during the working process. When the print head undergoes thermal deformation, it will squeeze the glass bead screws or other adjustment components connected to it, causing the glass bead screws and other adjustment components to change their positions compared to the original fixed positions, resulting in the print head shifting relative to the print head mounting seat, affecting the positioning accuracy of the print head during use, and further affecting the printing quality. Summary of the Invention

[0005] Based on the above problems, the purpose of the present invention is to provide a support base, an adjustment module, and an inkjet printing carriage, which can improve the positioning accuracy of the print head during the working process and enhance the printing quality.

[0006] To achieve the above purpose, the following technical solutions are provided:

[0007] In a first aspect, the present invention provides a support base, including:

[0008] A surrounding frame, which includes flexible arms, a first surrounding beam, and a second surrounding beam. The first surrounding beam and the second surrounding beam are arranged at intervals, and the first surrounding beam and the second surrounding beam are connected by the flexible arms. The flexible arms can abut against the print head;

[0009] An installation part, which is connected to the flexible arms. The installation part can abut against and connect to one end of the print head;

[0010] A positioning structure, which is arranged on the installation part. The positioning structure can abut against the side wall of the print head.

[0011] Optionally, the support base further includes a mounting boss, and the mounting boss and the positioning structure protrude from opposite sides of the mounting portion.

[0012] Specifically, the first enclosing beam includes a main body portion and a terminal portion. An avoidance surface is provided on one side of the main body portion close to the terminal portion, and the avoidance surface is inclined with respect to the horizontal plane. The flexible support arm is connected to the terminal portion.

[0013] Specifically, the positioning structure includes a first positioning member and a second positioning member. The first positioning member can abut against the printing nozzle along a first direction, and the second positioning member can abut against the printing nozzle along a second direction. The first direction and the second direction are arranged at an angle.

[0014] More specifically, the positioning structure further includes a positioning bump, and the positioning bump is provided on the mounting portion and can abut against the printing nozzle.

[0015] In a second aspect, the present invention further provides an adjustment module, including a mounting base, an adjustment structure, and the above-mentioned support base. The mounting base and the support base are detachably connected, and the adjustment structure can adjust the position of the support base relative to the mounting base.

[0016] Specifically, the adjustment structure includes a first adjustment member connected to the mounting base and / or a second adjustment member connected to the mounting base. The first adjustment member can adjust the position of the support base relative to the mounting base along a first direction, and the second adjustment member can adjust the position of the support base relative to the mounting base along a second direction. The first direction and the second direction are arranged at an angle.

[0017] More specifically, the first adjustment member is provided with a first driving surface, and the first enclosing beam is provided with a first driven surface. The first driven surface can move along the first direction under the pushing of the first driving surface; the second adjustment member is provided with a second driving surface, and the second enclosing beam is provided with a second driven surface. The second driven surface can move along the second direction under the pushing of the second driving surface.

[0018] Optionally, the adjustment module further includes a limiting structure. The limiting structure is provided on the mounting base. The limiting structure includes a first abutting portion and a second abutting portion. The first abutting portion abuts against the support base along a first direction, and the second abutting portion abuts against the support base along a second direction. The first direction and the second direction are arranged at an angle.

[0019] In a third aspect, the present invention further provides an inkjet printing carriage, including a printing nozzle and the above-mentioned adjustment module. The printing nozzle and the support base are detachably connected.

[0020] The beneficial effects of the present invention are:

[0021] The present invention provides a support base. When a print head is installed on the support base, a flexible arm abuts against the print head, and the installation part supports the print head. When the print head undergoes thermal deformation due to an increase in the temperature of the device, it will squeeze the enclosure frame, and the flexible arm will undergo flexible deformation to limit the displacement of the print head. The installation part and the enclosure frame are connected by the flexible arm, thereby reducing the influence of the thermal deformation of the print head on the installation part. Moreover, a positioning structure is provided on the installation part, and the positioning of the print head within the support base is also less affected by the thermal deformation of the print head, thus improving the positioning accuracy of the print head. The present invention also provides an adjustment module, which includes an installation base, an adjustment structure, and a support base. The adjustment structure can adjust the position of the support base relative to the installation base, thereby indirectly adjusting the position of the support base relative to the print head, restricting the displacement of the print head relative to the support base, and reducing the influence of thermal deformation on the self-positioning of the print head. In addition, the present invention further provides an inkjet printing carriage. Under the influence of thermal deformation, the print head will not produce excessive displacement, and the positioning accuracy is relatively high, and the overall printing quality of the inkjet printing carriage is good.

DETAILED DESCRIPTION

[0028] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Among them, the terms "first direction" and "second direction" are two different directions.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 3 As shown, the present embodiment provides a support seat, including an enclosure frame 2, a mounting portion 3 and a positioning structure 6. The enclosure frame 2 includes a flexible support arm 21, a first enclosure beam 22 and a second enclosure beam 23. The first enclosure beam 22 and the second enclosure beam 23 are arranged at intervals. The first enclosure beam 22 and the second enclosure beam 23 are connected by the flexible support arm 21, and the flexible support arm 21 can abut against the print head 1. The mounting portion 3 is connected to the flexible support arm 21, and the mounting portion 3 can support and be connected to one end of the print head 1. The positioning structure 6 is arranged on the mounting portion 3, and the positioning structure 6 can abut against the side wall of the print head 1. In order to adapt to the conventional shape of the print head 1, in the present embodiment, the first enclosure beam 22 and the second enclosure beam 23 are arranged in parallel. It should be noted that the shapes of the first enclosure beam 22 and the second enclosure beam 23 can be arranged in other forms according to actual application requirements.

[0032] When the print head 1 is installed on the support seat, the print head 1 is located between the first enclosure beam 22 and the second enclosure beam 23, the flexible support arm 21 and the print head 1 are in contact, and the mounting portion 3 is supported by the print head 1. During use, when the print head 1 is thermally deformed due to its own temperature increase, it will squeeze the surrounding enclosure frame 2, and the flexible support arm 21 will be flexibly deformed to limit the displacement of the print head 1. The mounting portion 3 and the enclosure frame 2 are connected by the flexible support arm 21, thereby reducing the influence of the thermal deformation of the print head 1 on the mounting portion 3. The positioning structure 6 is arranged on the mounting portion 3, and the influence of the thermal deformation of the print head 1 on the positioning of the print head 1 in the support seat is also reduced, and the positioning accuracy of the print head 1 is improved. In order to improve the structural strength of the enclosure frame 2, the first enclosure beam 22 and the second enclosure beam 23 can both contain rigid materials, such as stainless steel.

[0033] The specific structure of the support base in this embodiment is described below.

[0034] In order to improve the positioning effect of the print head 1 in the support seat, two mounting parts 3 are provided, and the two mounting parts 3 are respectively provided at the two ends of the print head 1. Correspondingly, a flexible arm 21 can be provided at each end of the print head 1, and the flexible arm 21 is connected to the first enclosure beam 22 and the second enclosure beam 23, and the flexible arm 21 is connected to the mounting part 3. The flexible arm 21 can be a plate-like structure with a thickness between 0.8mm-1.2mm. In other embodiments, a group of flexible components can also be provided at both ends of the print head 1, each group of flexible components includes two flexible arms 21, the two flexible arms 21 are connected to the second enclosure beam 23 and the first enclosure beam 22, and the two flexible arms 21 are located on both sides of the mounting part 3. In order to improve the deformation effect of the flexible arm 21, other numbers of flexible arms 21 can also be provided according to actual needs, and no excessive restrictions are made here.

[0035] like Figure 2 As shown, the support seat in this embodiment also includes a mounting boss 4, and the mounting boss 4 and the positioning structure 6 are convexly arranged on opposite sides of the mounting portion 3. After the mounting boss 4 is arranged, a certain distance is maintained between the support seat and the platform on which it is placed, thereby improving the heat dissipation of the print head 1 in the support seat, reducing the heat transferred to the support seat by the print head 1 during the printing operation, and reducing the influence of the thermal deformation of the print head 1 on the support seat, thereby improving the positioning accuracy of the print head 1 in the support seat. It should be noted that in other embodiments, the mounting boss 4 can also be arranged at the lower part of the first enclosure beam 22 and the lower part of the second enclosure beam 23, respectively.

[0036] The first enclosure beam 22 in this embodiment includes a main body 221 and a terminal 222. A relief surface 2211 is provided on one side of the main body 221 close to the terminal 222. The relief surface 2211 is inclined relative to the horizontal plane, and the flexible arm 21 is connected to the terminal 222. The relief surface 2211 can prevent the print head 1 from being completely fitted with the main body 221, and avoid excessive stress on the side of the main body 221 close to the terminal 222 when the print head 1 is thermally deformed, thereby ensuring the structural reliability of the first enclosure beam 22 and the stable operation of the print head 1. On the other hand, the relief surface 2211 can also prevent the flexible arm 21 connected to the terminal 222 from being damaged by excessive stress, and ensure that the flexible arm 21 can normally produce flexible deformation to disperse the force on the mounting portion 3. It is understandable that in order to ensure the structural reliability of the second enclosure beam 23 and the stable operation of the print head 1, the second enclosure beam 23 can adopt the same structural design as the first enclosure beam 22 to avoid the print head 1 and the second enclosure beam 23 being completely fitted.

[0037] Specifically, the positioning structure 6 in this embodiment includes a first positioning member 61 and a second positioning member 62. The first positioning member 61 can abut against the print head 1 along a first direction, and the second positioning member 62 can abut against the print head 1 along a second direction. The first direction and the second direction are set at an angle. The first positioning member 61 and the second positioning member 62 abut against the print head 1 along different directions, which improves the positioning effect of the positioning structure 6 on the print head 1. The first direction is the length direction of the support seat, and the second direction is the width direction of the support seat, which will not be repeated hereafter.

[0038] like Figure 2 and Figure 3 As shown, the positioning structure 6 may further include a positioning protrusion 63, which is disposed on the mounting portion 3 and can abut against the print head 1. In this embodiment, in order to enhance the positioning effect of the support seat on the print head 1, the print head 1 is provided with a mounting portion 3 on both sides along the first direction, a first positioning member 61 and a second positioning member 62 are provided on the mounting portion 3 on one side, and a positioning protrusion 63 is provided on the mounting portion 3 on the other side. The positioning protrusion 63 in this embodiment is V-shaped to adapt to the V-shaped notch of the print head 1. The shape of the positioning protrusion 63 can also be appropriately adjusted according to the shape of the print head 1, and no excessive restrictions are made here.

[0039] More specifically, in order to adapt to the shape of the print head 1 and facilitate processing, the first positioning member 61 and the second positioning member 62 can be rectangular positioning blocks fixedly arranged on the mounting portion 3, the first positioning member 61 extends along the second direction, and the second positioning member 62 extends along the first direction. The first positioning member 61, the second positioning member 62 and the mounting portion 3 can also be processed by an integrated molding process, and are integrally molded on the mounting portion 3, which simplifies the assembly process while also enhancing the connection strength between the first positioning member 61 and the second positioning member 62 and the mounting portion 3. In other embodiments, the first positioning member 61 can be provided with a first mounting hole, and the second positioning member 62 can also be provided with a second mounting hole, the first mounting hole is penetrated with a first fastener, and the second mounting hole is penetrated with a second fastener, the first fastener can be inserted into the first mounting hole and abut against the print head 1 along the first direction, and the second fastener can be inserted into the second mounting hole and abut against the print head 1 along the second direction. The provision of fasteners can reduce the influence of the installation or processing errors of the first positioning member 61 and the second positioning member 62 on the positioning of the print head 1, improve the installation positioning accuracy of the print head 1 initially placed on the support seat, and when the print head 1 is subsequently thermally deformed, the position of the print head 1 in the support seat can be adjusted by adjusting the fasteners, limiting the displacement of the print head 1 in the support seat, improving the positioning accuracy of the print head 1 during operation, and improving the printing quality. The fasteners can be nuts or bolts.

[0040] In this embodiment, the enclosure frame 2, the mounting portion 3, the mounting boss 4 and the positioning structure 6 are integrally formed to reduce the difficulty of assembling the support seat and enhance the connection effect between the components.

[0041] In the second aspect, the present invention also provides an adjustment module, including a mounting base 5, an adjustment structure 7 and the above-mentioned support base, the mounting base 5 and the support base are detachably connected, the adjustment structure 7 can adjust the position of the support base relative to the mounting base 5, and the mounting base 5 and the support base can be connected by bolts. When the print head 1 is placed on the support base, the adjustment structure 7 can be used to adjust the position of the support base relative to the mounting base 5, thereby achieving the adjustment of the position of the support base relative to the print head 1, and enhancing the positioning effect of the support base on the print head 1. In this embodiment, the support base is placed in the mounting base 5, and the mounting base 5 can provide stable support for the support base. The mounting base 5 can be designed to be rectangular and have a cavity that allows the print head 1 to be placed. Setting the mounting base 5 and setting it to a regular shape can expand the installation application scenario of the support base and improve the applicability of the support base.

[0042] In order to enhance the connection effect between the mounting base 5 and the support base, a glass bead screw may be provided on the first enclosure beam 22 and / or the second enclosure beam 23. In this embodiment, a glass bead screw is provided on the second enclosure beam 23. In order to reduce the heat transfer between the mounting base 5 and the support base, a step surface may be provided at one end of the first enclosure beam 22 and / or the second enclosure beam 23 close to the mounting base 5. The step height may be 0.5 mm.

The adjustment structure 7 can flexibly adjust the position of the support base in the first direction and / or the second direction, realize accurate adjustment of the position of the support base, thereby improving the positioning accuracy of the print head 1 installed in the support base and improving the printing quality.

[0044] More specifically, the first adjusting member 71 is provided with a first driving surface 711, and the first enclosure beam 22 is provided with a first driven surface 223. The first driven surface 223 can move in the first direction under the push of the first driving surface 711; the second adjusting member 72 is provided with a second driving surface 721, and the second enclosure beam 23 is provided with a second driven surface 231. The second driven surface 231 can move in the second direction under the push of the second driving surface 721. Through the cooperation of the first driving surface 711 and the first driven surface 223 and the cooperation of the second driving surface 721 and the second driven surface 231, the movement of the support seat in the first direction and the second direction can be achieved, and the position of the support seat can be adjusted. In this embodiment, the first adjusting member 71 and the second adjusting member 72 are both conical adjustment screws, including a conical adjustment block and a screw rod, the screw rod and the mounting base 5 are threadedly connected, and the conical adjustment block is inverted conical, that is, the first driving surface 711 and the second driving surface 721 are both conical surfaces of the outer wall of the conical adjustment block. Taking the first adjusting member 71 as an example, when the rotating conical adjusting block moves downward, its conical surface will gradually squeeze the first driven surface 223 provided on the first enclosure beam 22, thereby pushing the support seat to move along the first direction, thereby realizing the position adjustment of the support seat in the first direction.

[0045] In this embodiment, the adjustment structure 7 includes a first adjustment member 71 connected to the mounting base 5 and a second adjustment member 72 connected to the mounting base 5.

The first adjustment member 71 and the second adjustment member 72 can be provided on opposite sides of the support base, respectively, so that two operators can adjust the position of the support base on both sides at the same time, thereby improving the adjustment efficiency.

[0046] The adjustment module may further include a limiting structure 8, which is disposed on the mounting base 5. The limiting structure 8 includes a first abutting portion 81 and a second abutting portion 82. The first abutting portion 81 abuts against the support seat along a first direction, and the second abutting portion 82 abuts against the support seat along a second direction. The first direction and the second direction are arranged at an angle.

The first abutting portion 81 and the second abutting portion 82 can be spring plungers or any other elastic components, which are not limited here.

[0047] In the third aspect, the present invention also provides an inkjet printing carriage, comprising a print head 1 and the above-mentioned adjustment module, and the print head 1 and the support seat are detachably connected.
