DETAILED DESCRIPTION
[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0039] See also Figure 1 to Figure 6 A positioning and adjustment mechanism for an arrayed print head according to an embodiment of the present invention comprises a plurality of positioning and adjustment units 1 arranged in parallel, a fixing frame 2 for fixing the plurality of positioning and adjustment units 1, and a print head 3 arranged on each group of positioning and adjustment units 1; the positioning and adjustment unit 1 comprises a first adjustment component 11 connected to the fixing frame 2, a second adjustment component 12 connected to the first adjustment component 11, and a third adjustment component 13 connected to the second adjustment component 12; the print head 3 is arranged on the third adjustment component 13; the first adjustment component 11 is used to drive the print head 3 to rotate around the vertical direction, the second adjustment component 12 is used to drive the print head 3 to move linearly in the horizontal direction, and the third adjustment component 13 is used to drive the print head 3 to move linearly in the vertical direction.
[0040] In this embodiment, the positioning adjustment mechanism includes a fixing frame 2 and a plurality of positioning adjustment units 1, the plurality of positioning adjustment units 1 are arranged in parallel, and the fixing frame 2 fixes the plurality of positioning adjustment units 1. Each positioning adjustment unit 1 is provided with a print head 3, thereby forming a plurality of print heads 3 distributed in an array.
[0041] In this embodiment, an arrayed printing device is also provided, including the above-mentioned positioning adjustment mechanism of an arrayed printing head. It is foreseeable that: in actual implementation, the plurality of positioning adjustment units 1 are fixedly connected to the main body of the arrayed printing device through the fixing frame 2, and the plurality of positioning adjustment units 1 are installed on the main body of the arrayed printing device, so that the arrayed printing device can print through the plurality of printing heads 3 distributed in an array on the plurality of positioning adjustment units 1.
[0042] In the present application, each group of positioning and adjustment units 1 includes a first adjustment component 11, a second adjustment component 12 and a third adjustment component 13, the first adjustment component 11 is fixedly connected to the fixed frame 2, the second adjustment component 12 is connected to the first adjustment component 11, the third adjustment component 13 is connected to the second adjustment component 12, and the print head 3 is arranged on the third adjustment component 13. Therefore, the print head 3 is driven by the third adjustment component 13 to move linearly in the vertical direction, so that the position of the print head 3 in the Z-axis direction can be adjusted.
[0043] The third adjustment group is driven by the second adjustment component 12 to move linearly in the horizontal direction, thereby driving the print head 3 to move linearly in the horizontal direction. At the same time, the second adjustment component 12 is driven by the first adjustment component 11 to rotate around the vertical direction, thereby driving the third adjustment component 13 and the print head 3 to rotate around the vertical direction, thereby enabling the print head 3 to be adjusted in the X-axis direction and the Y-axis direction. Further, through the combined adjustment of the first adjustment component 11, the second adjustment component 12 and the third adjustment component 13, precise positioning of a single print head 3 is achieved.
[0044] Specifically, in actual implementation, the target position of the print head 3 in the X-axis, Y-axis, and Z-axis coordinate systems can be calculated through the software control system, and then the first adjustment component 11 and the second adjustment component 12 can be controlled to operate in coordination to make the print head 3 reach the target position in the X-axis and Y-axis coordinate systems; and then the third adjustment component 13 can be controlled to operate to make the print head 3 reach the target position in the Z-axis direction, thereby achieving precise positioning of the print head 3 in the X-axis, Y-axis, and Z-axis coordinate systems.
[0045] In this embodiment, multiple groups of positioning adjustment units 1 are used to position and adjust multiple array-distributed print heads 3 respectively, so that the array printing device can independently adjust the spacing between multiple array print heads 3 according to different printing requirements, thereby increasing the applicability of the array printing device in large-area, high-precision circuit manufacturing and reducing production costs.
[0046] And because a plurality of print heads 3 distributed in an array are respectively arranged on a plurality of groups of positioning adjustment units 1, the number of positioning adjustment units 1 on the fixing frame 2 can be increased or decreased by installing or disassembling the positioning adjustment units 1 on the fixing frame 2, so that the number of print heads 3 can be freely increased or decreased according to actual production needs, thereby further increasing the scope of application of array printing equipment in large-area, high-precision circuit manufacturing and reducing production costs.
[0047] In the present application, the position adjustment of the print head 3 in the X-axis direction and the Y-axis direction is achieved by combining the first adjustment component 11 driving the print head 3 to rotate in the vertical direction and the second adjustment component 12 driving the print head 3 to move linearly in the horizontal direction.
[0048] Compared with the prior art, in which the position adjustment of the print head 3 in the X-axis, Y-axis and Z-axis directions is achieved by means of three-way guides of the X-axis, Y-axis and Z-axis, the present embodiment can reduce the thickness of the positioning adjustment unit 1 in one direction, thereby reducing the space requirement of the positioning adjustment unit 1, and then increasing the number of arranged positioning adjustment units 1 within a limited space, that is, increasing the number of arranged print heads 3, which can not only increase the printing range of the arrayed printing device, reduce production costs, but also improve production efficiency.
[0049] In this embodiment, the first adjustment component 11 includes a connecting frame 111 fixedly connected to the fixed frame 2, a rotating shaft 112 arranged in the connecting frame 111 along the vertical direction, and a first driver arranged in the connecting frame 111. The second adjustment component 12 is rotatably connected to the rotating shaft 112, and the first driver cooperates with the second adjustment component 12 to drive the second adjustment component 12 to rotate around the rotating shaft 112.
[0050] In the present application, the first adjustment component 11 includes a connecting frame 111, a rotating shaft 112 and a first driver. The rotating shaft 112 is arranged in the connecting frame 111 along the vertical direction, the first driver is arranged in the connecting frame 111, the second adjustment component 12 is rotationally connected to the rotating shaft 112, and the third adjustment component 13 is connected to the second adjustment component 12, so that it is fixedly connected to the fixed frame 2 through the connecting frame 111, thereby realizing the fixation of the positioning adjustment unit 1 as a whole on the fixed frame 2.
[0051] Since the first driver cooperates with the second adjustment component 12, and the second adjustment component 12 is rotatably connected to the rotating shaft 112, the first driver can drive the second adjustment component 12 to rotate around the rotating shaft 112, thereby driving the third adjustment component 13 and the print head 3 arranged on the third adjustment component 13 to rotate synchronously around the rotating shaft 112, and then combined with the second adjustment component 12 to drive the print head 3 to move linearly in the horizontal direction, thereby realizing the adjustment of the position of the print head 3 in the X-axis direction and the Y-axis direction.
[0052] In this embodiment, a wedge block 126 is provided at one end of the second adjustment component 12, and a sliding slope 1261 is provided on one side of the wedge block 126. The first driver includes a first telescopic driving member 113 arranged in a vertical direction on the connecting frame 111, and an auxiliary positioning ball 114 cooperating with the sliding slope 1261. The telescopic rod of the first telescopic driving member 113 abuts against the auxiliary positioning ball 114.
[0053] In the present application, the first driver includes a first telescopic driving member 113 and an auxiliary positioning ball 114. The first telescopic driving member 113 is arranged in a vertical direction on the connecting frame 111, and the auxiliary positioning ball 114 is abutted against the telescopic rod of the first telescopic driving member 113. Therefore, when the telescopic rod of the first telescopic driving member 113 performs a telescopic movement, the auxiliary positioning ball 114 is pushed to move in the vertical direction.
[0054] A wedge block 126 is provided at one end of the second adjusting component 12, and a sliding slope 1261 is provided on one side of the wedge block 126. The auxiliary positioning ball 114 slides in cooperation with the sliding slope 1261. Therefore, when the first telescopic driving member 113 pushes the auxiliary positioning ball 114 to move in the vertical direction, the auxiliary positioning ball 114 cooperates with the sliding slope 1261 at different positions to push the second adjusting component 12 to rotate around the rotating shaft 112 at a certain angle, thereby driving the third adjusting component 13 and the print head 3 arranged on the third adjusting component 13 to rotate synchronously around the rotating shaft 112.
[0055] In this embodiment, the first driver further includes a first slide 115 disposed in the connection frame 111, and a first slide rail 1151 is disposed on the first slide 115, and the auxiliary positioning ball 114 is slidably matched with the first slide rail 1151. In the previous embodiment, it is mentioned that the first telescopic driving member 113 pushes the auxiliary positioning ball 114 to move in the vertical direction. In this application, the first driver further includes a first slide 115, and the first slide 115 is disposed in the connection frame 111.
[0056] A first slide rail 1151 is provided on the first slide seat 115. The first slide rail 1151 extends in the vertical direction on the first slide seat 115. The auxiliary positioning ball 114 slides with the first slide rail 1151 through the auxiliary positioning ball 114. Therefore, when the first telescopic driving member 113 pushes the auxiliary positioning ball 114 to move in the vertical direction, the first slide rail 1151 guides the vertical movement of the auxiliary positioning ball 114, thereby making the sliding cooperation between the auxiliary positioning ball 114 and the sliding slope 1261 more stable, thereby enhancing the rotation stability of the second adjustment component 12.
[0057] It is mentioned in the previous embodiment that in the present application, the auxiliary positioning ball 114 is in contact with the telescopic rod of the first telescopic driving member 113, so that when the telescopic rod of the first telescopic driving member 113 is extended and retracted, the auxiliary positioning ball 114 is pushed to move in the vertical direction.
[0058] In this embodiment, the first driver also includes a tension spring 116, and a pull rod 1141 is provided on both sides of the auxiliary positioning ball 114. One end of the tension spring 116 is fixedly connected to the first sliding seat 115, and the other end is fixedly connected to the pull rod 1141, so that the auxiliary positioning ball 114 is pulled by the tension springs 116 on both sides, so that the auxiliary positioning ball 114 remains in contact with the first telescopic driving member 113.
[0059] Specifically, in actual implementation, the pull rod 1141 can be set on the left and right sides of the auxiliary positioning ball 114 , the front side of the auxiliary positioning ball 114 slides with the first slide rail 1151 , and the rear side of the auxiliary positioning ball 114 slides with the sliding slope 1261 .
[0060] Therefore, when the telescopic rod of the first telescopic driving member 113 is extended, the auxiliary positioning ball 114 is pushed to move vertically downward along the first sliding rail 1151, so that the auxiliary positioning ball 114 cooperates with different positions of the sliding slope 1261, thereby pushing the second adjusting component 12 to rotate around the rotating shaft 112 at a certain angle. At this time, the tension springs 116 on the left and right sides of the auxiliary positioning ball 114 are stretched.
[0061] When the telescopic rod of the first telescopic driving member 113 retracts, under the elastic force of the tension spring 116 restoring its own deformation, the auxiliary positioning ball 114 maintains abutment with the telescopic rod of the first telescopic driving member 113, so that the auxiliary positioning ball 114 moves vertically upward synchronously with the telescopic rod of the first telescopic driving member 113.
[0062] In this embodiment, the first driver further includes a first return spring 117, one end of which is connected to the second adjustment component 12, and the other end of which is connected to the first slide seat 115. When the telescopic rod of the first telescopic driving member 113 is extended, the auxiliary positioning ball 114 is pushed to move vertically downward along the first slide rail 1151, and the second adjustment component 12 is pushed to rotate around the rotation axis 112 at a certain angle by the cooperation of the auxiliary positioning ball 114 and the sliding inclined surface 1261 at different positions, the first return spring 117 is stretched.
[0063] When the telescopic rod of the first telescopic driving member 113 retracts and the auxiliary positioning ball 114 moves vertically upward following the telescopic rod of the first telescopic driving member 113, the first return spring 117 restores its own deformation and pulls the second adjusting component 12 to rotate in the opposite direction by a certain angle in the horizontal direction, and the sliding inclined surface 1261 on one side of the second adjusting component 12 always keeps in cooperation with the auxiliary positioning ball 114, thereby ensuring the follow-up performance of the second adjusting component 12 following the movement of the auxiliary positioning ball 114, thereby realizing the forward and reverse rotation of the second adjusting component 12 in the horizontal direction.
[0064] Since in this positioning and adjustment mechanism, the first telescopic driving member 113 and the print head 3 are respectively arranged on both sides of the rotating shaft 112, and the first telescopic driving member 113 on one side of the rotating shaft 112 is operated to drive the print head 3 on the other side of the rotating shaft 112 to rotate around the rotating shaft 112 at a certain angle, the distance from the first telescopic driving member 113 to the rotating shaft 112 can be regarded as the lever arm length of the driving end, and the distance from the print head 3 to the rotating shaft 112 can be regarded as the lever arm length of the controlled end.
[0065] In the present application, the distance from the first telescopic driving member 113 to the rotating shaft 112 and the distance from the print head 3 to the rotating shaft 112 can be unequal, that is, the length of the force arm at the driving end and the length of the force arm at the controlled end are unequal. Specifically, in actual implementation, the distance from the first telescopic driving member 113 to the rotating shaft 112 and the distance from the print head 3 to the rotating shaft 112 can be designed in the following two implementations.
[0066] Embodiment 1:
[0067] In this embodiment, the distance from the first telescopic driving member 113 to the rotating shaft 112 is greater than the distance from the print head 3 to the rotating shaft 112, that is, the length of the force arm at the driving end is greater than the length of the force arm at the controlled end, thereby forming a force-saving lever. Therefore, the displacement input at the driving end is reduced at the controlled end, thereby improving the positioning accuracy of the print head 3.
[0068] Embodiment 2:
[0069] In this embodiment, the distance from the first telescopic driving member 113 to the rotating shaft 112 is smaller than the distance from the print head 3 to the rotating shaft 112, that is, the length of the force arm at the driving end is smaller than the length of the force arm at the controlled end, thereby forming a force lever. Therefore, the displacement input at the driving end is amplified at the controlled end, thereby increasing the adjustment stroke of the print head 3.
[0070] The above two implementation modes correspond to two production requirements respectively, so in actual implementation, a selection can be made according to actual production needs.
[0071] In this embodiment, the second adjustment component 12 includes a rotating seat 121 rotatably connected to the rotating shaft 112, a second slide rail 122 extending horizontally on the rotating seat 121, a second slide seat 123 slidably connected to the second slide rail 122, and a second driver connected to the second slide seat 123, the second driver is used to drive the second slide seat 123 to move along the second slide rail 122, and the third adjustment component 13 is fixedly connected to the second slide seat 123.
[0072] In the present application, the second adjustment assembly 12 includes a rotating seat 121 and a second slide rail 122, the rotating seat 121 is rotatably connected to the rotating shaft 112, and the second slide rail 122 extends horizontally on the rotating seat 121. In a specific implementation, a wedge block 126 is disposed at one end of the second slide rail 122 away from the rotating seat 121, and a sliding inclined surface 1261 is formed on the front side of the wedge block 126, so that the auxiliary positioning ball 114 cooperates with different positions of the sliding inclined surface 1261 to push the second slide rail 122 to rotate around the rotating shaft 112 at a certain angle, thereby realizing the rotation of the second adjustment assembly 12 around the rotating shaft 112.
[0073] In the present application, the second adjustment component 12 also includes a second slide 123 and a second driver. The second slide 123 is slidably connected to the second slide rail 122. The second driver is connected to the second slide 123. The third adjustment component 13 is fixedly connected to the second slide 123, so that the second driver drives the second slide 123 to move horizontally on the second slide rail 122, thereby driving the third adjustment component 13 and the print head 3 arranged on the third adjustment component 13 to move linearly in the horizontal direction synchronously.
[0074] In this embodiment, the second driver includes a second telescopic driving member 124 and a second return spring 125, and the second telescopic driving member 124 and the second return spring 125 are both arranged parallel to the second slide rail 122. The main body of the second telescopic driving member 124 is fixedly connected to the second slide seat 123, and the telescopic rod of the second telescopic driving member 124 abuts against the rotating seat 121, and one end of the second return spring 125 is fixedly connected to the rotating seat 121, and the other end is fixedly connected to the second slide seat 123.
[0075] Specifically, in actual implementation, the second telescopic driving member 124 can be arranged on one side of the second slide rail 122, and the second reset spring 125 can be arranged on the other side opposite to the second slide rail 122. When the telescopic rod of the second telescopic driving member 124 extends outward on the main body of the second telescopic driving member 124, under the abutment of the rotating seat 121, the main body of the second telescopic driving member 124 moves in a direction away from the rotating seat 121, thereby driving the second slide seat 123 to move linearly on the second slide rail 122. At this time, the second reset spring 125 is stretched, thereby driving the third adjustment assembly 13 and the print head 3 arranged on the third adjustment assembly 13 to move linearly in the horizontal direction.
[0076] When the telescopic rod of the second telescopic driving member 124 retracts on the second telescopic driving member 124 body, the second return spring 125 restores its own deformation force to act on the second slide seat 123, so that the telescopic rod of the second telescopic driving member 124 remains in abutment with the rotating seat 121, so that under the abutment of the rotating seat 121, the second telescopic driving member 124 body moves toward the rotating seat 121, and at the same time drives the second slide seat 123 to move in the reverse linear direction on the second slide rail 122, thereby driving the third adjustment component 13 and the print head 3 arranged on the third adjustment component 13 to move in the reverse linear direction along the horizontal direction.
[0077] In this embodiment, the third adjustment component 13 includes a third slide rail 131 extending in a vertical direction on one side of the connecting frame 111, a base 132 fixedly connecting the third slide rail 131 to the second adjustment component 12, a third slide seat 133 slidably connected to the third slide rail 131, and a third driver connected to the third slide seat 133. The third driver is used to drive the third slide seat 133 to move along the third slide rail 131, and the print head 3 is arranged on the third slide seat 133.
[0078] In the present application, the third adjustment component 13 includes a third slide rail 131 and a base 132. The third slide rail 131 extends in the vertical direction on one side of the connecting frame 111. The base 132 fixedly connects the third slide rail 131 with the second slide seat 123 of the second adjustment component 12, so that when the second slide seat 123 moves back and forth in the horizontal direction on the second slide rail 122, the third adjustment component 13 is driven to move back and forth in the horizontal direction as a whole.
[0079] In the present application, the third adjustment component 13 also includes a third slide 133 and a third driver. The third slide 133 is slidably connected to the third slide rail 131. The third driver is connected to the third slide 133. The print head 3 is arranged on the third slide 133. The third drive drives the third slide 133 to move in the vertical direction on the third slide rail 131, thereby driving the print head 3 to move linearly in the vertical direction synchronously.
[0080] In this embodiment, the third driver includes a third telescopic driving member 134 and a third return spring 135, and the third telescopic driving member 134 and the third return spring 135 are both arranged in parallel with the third slide rail 131. The main body of the third telescopic driving member 134 is fixedly connected to the third slide seat 133, and the telescopic rod of the third telescopic driving member 134 abuts against the base 132, and one end of the third return spring 135 abuts against the base 132, and the other end abuts against the third slide seat 133.
[0081] Specifically, in actual implementation, the third telescopic driving member 134 may be disposed above the base 132 , and the third return spring 135 may be disposed below the base 132 and between the base 132 and the third slide seat 133 .
[0082] When the telescopic rod of the third telescopic driving member 134 extends outward on the main body of the third telescopic driving member 134, under the abutment of the base 132, the main body of the third telescopic driving member 134 is pushed away from the base 132, thereby driving the third slide 133 to move vertically upward on the third slide rail 131. At this time, the third return spring 135 is compressed, and then drives the print head 3 to move vertically upward synchronously through the third slide 133.
[0083] When the telescopic rod of the third telescopic driving member 134 retracts on the main body of the third telescopic driving member 134, the elastic force of the third reset spring 135 to restore its own deformation acts on the third slide 133, so that the telescopic rod of the third telescopic driving member 134 remains in abutment with the base 132, so that under the abutment of the base 132, the main body of the third telescopic driving member 134 moves toward the direction close to the base 132, driving the third slide 133 to move vertically downward on the third slide rail 131, and then driving the print head 3 to move vertically downward synchronously.
[0084] In this embodiment, the third driver further includes a guide post 136 fixedly connected to the third slide 133, a guide hole for the guide post 136 to be inserted is provided on the base 132, and the third return spring 135 is sleeved on the guide post 136. In the previous embodiment, it is mentioned that the third return spring 135 is arranged below the base 132 and between the base 132 and the third slide 133.
[0085] Specifically, in the present application, the third driver also includes a guide column 136, which is fixedly connected to the third slide seat 133, and the third return spring 135 is sleeved on the guide column 136, so that the third return spring 135 is guided by the guide column 136, so that the telescopic movement of the third return spring 135 is more stable.
[0086] A guide hole is provided at a corresponding position on the base 132. When the third slide 133 moves in the vertical direction on the third slide rail 131, the guide post 136 on the third slide 133 is plugged into the guide hole on the base 132. On the one hand, the third return spring 135 sleeved on the guide post 136 can abut against the base 132; on the other hand, the movement of the third slide 133 on the third slide rail 131 can be guided by the plug-in cooperation between the guide post 136 and the guide hole, so that the movement of the print head 3 in the vertical direction is more stable.
[0087] Specifically, in the present embodiment, the first telescopic driving member 113, the second telescopic driving member 124 and the third telescopic driving member 134 may be telescopic driving members such as electric telescopic cylinders and electric differential heads.
[0088] Since in the present application, the positioning adjustment mechanism is an arrayed printing device for large-area, high-precision circuits, in order to further ensure the printing accuracy of large-area, high-precision circuits, preferably, in the present embodiment, the first telescopic drive member 113, the second telescopic drive member 124 and the third telescopic drive member 134 use electric micrometer heads.
[0089] It can be foreseen that: when the first telescopic drive member 113, the second telescopic drive member 124 and the third telescopic drive member 134 adopt an electric micrometer head, the second telescopic drive member 124 body and the third telescopic drive member 134 body mentioned in the above text are the cylinder of the electric micrometer head, and the telescopic rod of the first telescopic drive member 113, the telescopic rod of the second telescopic drive member 124, and the telescopic rod of the third telescopic drive member 134 are the measuring rods of the electric micrometer head.
[0090] In this embodiment, the first adjustment component 11 realizes the rotation of the print head 3 in the horizontal direction through the sliding cooperation between the auxiliary positioning ball 114 and the sliding inclined surface 1261, and the second adjustment component 12 and the third adjustment component 13 realize the linear movement of the print head 3 through the sliding cooperation between the slide seat and the slide rail. It can be foreseen that the first adjustment component 11 can perform high-precision positioning adjustment on the print head 3, and the second adjustment component 12 and the third adjustment component 13 can perform large-stroke positioning adjustment on the print head 3.
[0091] Therefore, the present application is based on the required positioning characteristics, thereby forming the required high-precision adjustment components (first adjustment components 11) and long-stroke direct-drive adjustment components (second adjustment components 12 and third adjustment components 13), so that the positioning adjustment mechanism can meet both the high-precision positioning adjustment requirements of the print head 3 and the long-stroke positioning adjustment requirements of the print head 3, thereby increasing the scope of application of arrayed printing equipment in large-area, high-precision circuit manufacturing and reducing production costs.
