It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0031] like Figure 1 and Figure 2As shown, the preferred embodiment of the present utility model provides an MLCC block automatic marking device, which includes a first fixed base 1, a second fixed base 2, a first longitudinal slide rail 3, a second longitudinal slide rail 4, a transverse slide rail 5, a vertical slide rail 6, a first movable adapter 7, a second movable adapter 8, a horizontal slide 9, a lifting slide 10, a first fixed adapter 11, a second fixed adapter 12, an X-axis motor 13, a Y-axis motor 14, a Z-axis motor 15, a first mounting bracket 16, a second mounting bracket 17, a third mounting bracket 18, a first belt drive assembly 19, a second belt drive assembly 20, a third belt drive assembly 21 and a marking pen head 22;

[0032] The first fixing seat 1 and the second fixing seat 2 are arranged symmetrically on the left and right, and both serve as supporting parts of the entire device. For example, they can be connected to an external three-dimensional moving device through a lifting mounting frame, so that the entire device can achieve three-dimensional movement, so as to facilitate the entire device to be moved above the block accumulation area for marking operations.

[0033] The first longitudinal slide rail 3 is fixed to the first fixed seat 1 and extends in the front-to-back direction, and the first movable adapter 7 is slidably connected to the first longitudinal slide rail 3; the second longitudinal slide rail 4 is fixed to the second fixed seat 2 and extends in the front-to-back direction, and the second movable adapter 8 is slidably connected to the second longitudinal slide rail 4; the two ends of the transverse slide rail 5 are respectively fixedly connected to the first movable adapter 7 and the second movable adapter 8, and the transverse slide rail 5 is perpendicular to the first longitudinal slide rail 3 and the second longitudinal slide rail 4 (that is, the transverse slide rail 5 extends in the left-right direction), and the horizontal slide 9 is slidably connected to the transverse slide rail 5; the third mounting bracket 18 is fixed to the horizontal slide 9, the vertical slide rail 6 is fixed to the third mounting bracket 18 and extends in the up-down direction, and the lifting slide 10 is slidably connected to the vertical slide rail 6. This design enables the marking pen tip 22 to move stably in the front-to-back, left-to-right, and up-down directions, which is conducive to accurate marking of the marking pen tip 22.

[0034] To facilitate assembly of the first belt drive assembly 19 and the second belt drive assembly 20, the first movable adapter 7, the second movable adapter 8, the first fixed adapter 11, and the second fixed adapter 12 are respectively provided as mounting components for connecting the guide wheels of the first belt drive assembly 19 and the second belt drive assembly 20. The first fixed adapter 11 is fixed to the rear end of the first fixing base 1, and the second fixed adapter 12 is fixed to the rear end of the second fixing base 2.

[0035] The X-axis motor 13 is fixed to the front end of the first fixed base 1 via the first mounting bracket 16. The power output end of the X-axis motor 13 is connected to the horizontal slide 9 via the first belt transmission assembly 19. When the X-axis motor 13 is driven, the X-axis motor 13 can drive the horizontal slide 9 to move left and right via the first belt transmission assembly 19.

[0036] In this embodiment, the first belt transmission assembly 19 includes a first driving wheel 191, a first upper guide wheel 192, a second upper guide wheel 193, a third upper guide wheel 194, a fourth upper guide wheel 195 and a first belt 196 located at the same horizontal height. The first driving wheel 191, the first upper guide wheel 192, the second upper guide wheel 193, the third upper guide wheel 194, and the fourth upper guide wheel 195 are arranged in sequence along the winding direction of the first belt 196. The first driving wheel 191 is aligned with the X-axis. The power output end of the motor 13 is connected, the first upper guide wheel 192 is rotatably set on the first movable adapter 7, the second upper guide wheel 193 is rotatably set on the second movable adapter 8, the third upper guide wheel 194 is rotatably set on the second fixed adapter 12, and the fourth upper guide wheel 195 is rotatably set on the first fixed adapter 11; the first belt 196 is fixedly connected to the horizontal slide 9, and the horizontal slide 9 is provided with a belt clamp for clamping the first belt 196. Thus, the first driving wheel 191, the first upper guide wheel 192, the second upper guide wheel 193, the third upper guide wheel 194 and the fourth upper guide wheel 195 form a fixed rotation size. When the X-axis motor 13 is driven, the forward or reverse rotation of the first driving wheel 191 can drive the first belt 196 to reciprocate around each upper guide wheel, thereby driving the horizontal slide 9 fixedly connected to the first belt 196 to move in the left and right directions.

[0037] The Y-axis motor 14 is fixed to the front end of the second fixing base 2 via the second mounting bracket 17. The power output end of the Y-axis motor 14 is connected to the first movable adapter 7 and the second movable adapter 8 via the second belt transmission assembly 20. When the Y-axis motor 14 is driven, the Y-axis motor 14 can drive the first movable adapter 7 and the second movable adapter 8 to move forward and backward together via the second belt transmission assembly 20.

[0038] In this embodiment, the second belt transmission assembly 20 includes a second driving wheel 201, a first lower guide wheel 202, a second lower guide wheel 203, a third lower guide wheel 204, a fourth lower guide wheel 205 and a second belt 206 located at the same horizontal height. The second driving wheel 201, the first lower guide wheel 202, the second lower guide wheel 203, the third lower guide wheel 204 and the fourth lower guide wheel 205 are arranged in sequence along the winding direction of the second belt 206. The second driving wheel 201 is connected to the power output end of the Y-axis motor 14, the first lower guide wheel 202 is fixedly set on the second movable adapter 8, the second lower guide wheel 203 is fixedly set on the first movable adapter 7, the third lower guide wheel 204 is rotatably set on the first fixed adapter 11, and the fourth lower guide wheel 205 is rotatably set on the second fixed adapter 12; the second belt 206 is fixedly connected to the first lower guide wheel 202 or the second lower guide wheel 203. Thus, the second driving wheel 201, the first lower guide wheel 202, the second lower guide wheel 203, the third lower guide wheel 204 and the fourth lower guide wheel 205 can make the second belt 206 form a fixed rotation size. When the Y-axis motor 14 is driven, the forward or reverse rotation of the second driving wheel 201 can drive the second belt 206 to reciprocate around each lower guide wheel, thereby driving the first movable adapter 7 (that is, the second belt 206 is fixedly connected to the second lower guide wheel 203) and the second movable adapter 8 (that is, the second belt 206 is fixedly connected to the first lower guide wheel 202) fixedly connected to the second belt 206 to move together in the forward and backward directions.

[0039] The Z-axis motor 15 is fixed to the third mounting bracket 18, and the power output end of the Z-axis motor 15 is connected to the lifting slide 10 through the third belt transmission assembly 21. When the Z-axis motor 15 is driven, the Z-axis motor 15 can drive the lifting slide 10 to move up and down through the third belt transmission assembly 21.

[0040] In this embodiment, the third belt drive assembly 21 includes a third drive wheel 211, a third guide wheel 212, and a third belt 213. The third drive wheel 211 and the third guide wheel 212 are arranged vertically and are rotatably mounted on the third mounting bracket 18. The third belt 213 is wound around the third drive wheel 211 and the third guide wheel 212. The third belt 213 is fixedly connected to the lifting slide 10. When the Z-axis motor 15 is driven, the forward or reverse rotation of the third drive wheel 211 drives the third belt 213 to reciprocate around the upper guide wheels, thereby driving the lifting slide 10, which is fixedly connected to the third belt 213, to move in the vertical direction.

[0041] The marking pen tip 22 is vertically mounted on the lifting slide 10. The marking pen tip 22 is preferably an inductive retractable pen tip, which determines the writing position by compressing a certain amount. At the same time, the MLCC block automatic marking device also includes a control cabinet 23, which is mounted on the first fixed seat 1 or the second fixed seat 2, and the control cabinet 23 is respectively connected to the marking pen tip 22, the X-axis motor 13, the Y-axis motor 14 and the Z-axis motor 15. Thus, the control cabinet 23 can control the X-axis motor 13, the Y-axis motor 14 and the Z-axis motor 15 according to the feedback signal of the marking pen tip 22 to automatically write the product batch number specifications on the block.

[0042] Furthermore, in order to achieve precise automatic writing, the X-axis motor 13 , the Y-axis motor 14 and the Z-axis motor 15 are preferably servo motors.

[0043] Furthermore, in order to prevent slippage between the first belt 196 and the upper guide wheel, the second upper guide wheel 193 and the third upper guide wheel 194 are both provided with teeth that mesh with the inner tooth surface of the first belt 196 .

[0044] Furthermore, to prevent slippage between the second belt 206 and the lower guide wheel, the second lower guide wheel 203 and the third lower guide wheel 204 are each provided with teeth that mesh with the inner tooth surface of the second belt 206. It should be noted that because the second lower guide wheel 203 is fixed to the first movable adapter 7, when it meshes with the second belt 206, the second belt 206 and the first movable adapter 7 are relatively fixedly connected. In other words, the second belt 206 can pull the second lower guide wheel 203 to achieve movement of the first movable adapter 7.

[0045] In summary, the MLCC block automatic marking device of the embodiment of the present invention is an organic combination of a longitudinal slide rail, a transverse slide rail, a vertical slide rail, a movable adapter, a horizontal slide, a lifting slide, an X-axis motor, a Y-axis motor, a Z-axis motor, a first belt drive assembly, a second belt drive assembly, a third belt drive assembly, and a marking pen tip; when the X-axis motor is driven, it can drive the horizontal slide to move left and right through the first belt drive assembly; when the Y-axis motor is driven, it can drive the movable adapter to move forward and backward through the second belt drive assembly; when the Z-axis motor is driven, it can drive the lifting slide to move up and down through the third belt drive assembly; the marking pen tip is installed on the lifting slide. As a result, the marking pen tip can stably move in the front-back, left-right, and up-down directions, and accurately mark the blocks, thereby realizing the automation of block marking, reducing employee operation time, and effectively reducing the loose quality problems of the blocks during transportation.

[0046] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
