[0040] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0041] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0042] This invention provides a screen printing device, which includes a drive unit 100. The screen printing device is used to print conductive paste with a specific pattern onto the surface of a solar cell, and is a key piece of equipment in the manufacturing process of solar cells. The drive unit 100 can be used to drive the printing table to move.

[0043] like Figure 1-8 As shown, the drive device 100 includes a base 10, a sliding assembly 20, and a sliding seat 30. The sliding assembly 20 includes a slide rail 21 connected to the base 10, a slider 22 slidably connected to the slide rail 21, and a lubrication structure formed between the slide rail 21 and the slider 22. The lubrication structure includes an oil inlet 23 for receiving lubricating oil. The lubrication structure allows lubricating oil to flow between the slide rail 21 and the slider 22. After the lubricating oil is injected from the oil inlet 23, it can flow between the slider 22 and the slide rail 21, thereby lubricating the slide rail 21 and the slider 22.

[0044] The sliding seat 30 is connected to the slider 22. When the slider 22 slides relative to the slide rail 21, the sliding seat 30 moves along with the slider 22. The sliding seat 30 is essentially slidably connected to the base 10 via the sliding assembly 20. The sliding seat 30 is provided with an oil inlet 80 that connects to the oil inlet 23. After lubricating oil is injected into the oil inlet 80, the lubricating oil can flow to the oil inlet 23 of the lubrication structure, and then flow from the oil inlet 23 to the space between the slide rail 21 and the slider 22. The oil inlet 80 and the oil inlet 23 can be connected by a pipe formed inside the sliding seat 30 and a pipe located outside the sliding seat 30. In this embodiment, the oil inlet 23 is located on the slider 22 and can move with the slider 22.

[0045] The drive unit 100 also includes an oil supply device 40. The oil supply device 40 is connected to the base 10. When the sliding seat 30 slides to a preset position, the oil supply device 40 can dock with the oil filling port 80. After the oil supply device 40 docks with the oil filling port 80, the oil supply device 40 can inject lubricating oil into the oil filling port 80.

[0046] The oil inlet 80 and the oil supply device 40 can engage during the sliding of the sliding seat 30. That is, after the sliding seat 30 moves to a position where the oil inlet 80 and the oil supply device 40 can engage, the oil supply device 40 can inject lubricating oil into the oil inlet 80. Then, the lubricating oil can flow to the oil inlet 23 and then flow between the slide rail 21 and the slider 22 to lubricate the slide rail 21 and the slider 22.

[0047] In this embodiment, when the drive device 100 is in use, after the sliding seat 30 moves to a predetermined position, the lubrication device 40 injects lubricating oil into the oil injection port 80, thereby lubricating the slide rail 21 and the slider 22. After the lubrication is completed, the sliding seat 30 can continue to move. In this way, not only can oil be automatically supplied to lubricate the slide rail 21 and the slider 22, but there is also no need to set up an oil supply pipeline that deforms with the movement of the sliding seat 30, avoiding frequent bending of the pipeline during the movement of the sliding seat 30 and leakage, making the operation of the drive device 100 more stable and reliable.

[0048] It should be noted that the above-mentioned lubrication structure is the structure on the existing sliding assembly 20, and its specific features are not described here.

[0049] The lubrication device 40 includes a lubrication nozzle 41, which has two states: open and closed. When the lubrication nozzle 41 is open, lubricating oil can be output through it; when the lubrication nozzle 41 is closed, lubricating oil cannot be output through it. The lubrication device 40 also includes a first drive member 42 for controlling the opening and closing of the lubrication nozzle 41. Under the control of the first drive member 42, the lubrication nozzle 41 can automatically open and close. When the lubrication device 40 is connected to the oil filling port 80, the oil filling port 80 is connected to the lubrication nozzle 41.

[0050] With the above configuration, when the oil inlet 80 and the oil nozzle 41 are not connected, the first drive unit 42 controls the oil nozzle 41 to be in a closed state to prevent lubricating oil leakage. When the sliding seat 30 moves to the position where the oil inlet 80 and the oil nozzle 41 are connected, the first drive unit 42 needs to control the oil nozzle 41 to open so that lubricating oil can be injected into the oil inlet 80. In this way, the timing of oil injection into the lubrication structure can be further controlled, so that the oil nozzle 41 will only open to inject lubricating oil into the lubrication structure when lubrication is needed between the slide rail 21 and the slider 22, making the oil injection process more controllable.

[0051] The lubrication device 40 may also include an oil pump 70. The oil pump 70 is connected to the oil nozzle 41. When the oil nozzle 41 is connected to the oil filling port 80, the oil pump 70 works, enabling lubricating oil to flow into the oil filling port 80 through the oil nozzle 41.

[0052] The grease nozzle 41 includes a main body 411 and a control lever 412 rotatably disposed relative to the main body 411. The control lever 412 rotates relative to the main body 411 to control the opening and closing of the grease nozzle 41. A first drive member 42 is used to control the rotation of the control lever 412 relative to the main body 411, thereby controlling the opening and closing of the grease nozzle 41.

[0053] With the above settings, the opening and closing of the oil nozzle 41 can be automatically controlled by controlling the first drive component 42, without manual intervention. The drive device 100 is more intelligent and saves labor costs.

[0054] The first driving component 42 is a cylinder, which includes a cylinder body 421 and a telescopic rod 422 that is telescopically disposed relative to the cylinder body 421. The telescopic rod 422 extends and retracts in the radial direction of the oil nozzle 41 to control the rotation of the control rod 412.

[0055] Specifically, the control lever 412 can rotate relative to the main body 411 between a first position and a second position. When the control lever 412 is in the first position, the angle between the control lever 412 and the main body 411 is the first angle, and the oil nozzle 41 is in the closed state. When the control lever 412 is in the second position, the angle between the control lever 412 and the main body 411 is the second angle, and the oil nozzle is in the open state. The first angle is greater than the second angle. When the telescopic rod 422 extends relative to the cylinder body 421, it can drive the control lever 412 to rotate from the first position to the second position, thereby opening the oil nozzle 41. The oil nozzle 41 is provided with an elastic element. When the telescopic rod 422 retracts relative to the cylinder body 421, the control lever 412 can rotate from the second position to the first position under the action of the elastic element, thereby closing the oil nozzle 41. The oil nozzle 41 can specifically be a single-handle locking nozzle.

[0056] In this embodiment, the oil supply device 40 further includes a connecting seat 43 connected to the base 10, and the oil supply nozzle 41 and the first driving member 42 are both connected to the connecting seat 43. The axis of the oil supply nozzle 41 extends along the sliding direction of the sliding seat 30, and the position of the oil supply nozzle 41 relative to the connecting seat 43 is adjustable along the sliding direction of the sliding seat 30.

[0057] In this text, the slide rail 21 extends along the length of the base 10, and the sliding direction of the sliding seat 30 is the same as the length direction of the base 10. The length direction of the base 10 is where the base 10 is located. Figure 1 The left and right directions of the base 10 in the state shown are as follows: the height direction of the base 10 is as shown. Figure 1 The up and down directions in the shown state.

[0058] Adjusting the position of the grease nipple 41 relative to the connecting seat 43 along the sliding direction of the sliding seat 30 allows the oil filling port 80 to dock with the grease nipple 41 in a suitable position, avoiding improper docking of the grease nipple 41 and the oil filling port 80, which could cause lubricating oil leakage or damage to the grease nipple 41 and the oil filling port 80.

[0059] Specifically, the connecting seat 43 includes a first clamping part 431 and a second clamping part 432 that jointly clamp the oil nozzle 41. The first clamping part 431 and the second clamping part 432 are located on both sides of the oil nozzle 41 in the radial direction, and the second clamping part 432 is detachably connected to the first clamping part 431.

[0060] The first clamping part 431 and the second clamping part 432 clamp the oil supply nozzle 41, fixing its position. Separating the second clamping part 432 from the first clamping part 431 allows adjustment of the oil supply nozzle 41's position along the sliding direction of the sliding seat 30. Once the oil supply nozzle 41 is in the correct position, connecting the second clamping block to the first clamping part 431 maintains the oil supply nozzle 41 in its adjusted position. The first clamping part 431 and the second clamping part 432 can be detachably connected together using fasteners such as screws.

[0061] The connecting seat 43 is also provided with an anti-rotation structure 433 to limit the rotation of the oil nozzle 41 relative to the connecting seat 43. When the first driving member 42 controls the control rod 412 to rotate, the anti-rotation structure 433 can prevent the oil nozzle 41 from rotating, thus ensuring the positional accuracy of the oil nozzle 41 and enabling the oil nozzle 41 to stably inject lubricating oil into the oil filling port 80.

[0062] The grease nozzle 41 includes a first plane 413 and a second plane 414 located on both sides of its radial direction. The first plane 413 and the second plane 414 are parallel or angled together. The anti-rotation structure 433 includes a support 434 connected to the connecting seat 43. The support 434 has a through hole 4341 through which the grease nozzle 41 passes. The sidewall of the through hole 4341 includes a first sidewall 4342 opposite to the first plane 413 and a second sidewall 4343 opposite to the second plane 414. The first plane 413 and the second plane 414 are located between the first sidewall 4342 and the second sidewall 4343, which can restrict the rotation of the grease nozzle 41.

[0063] It is conceivable that other structures, not limited to the structure of the support base 434, could be used to restrict the rotation of the oil nozzle 41.

[0064] In this embodiment, at least two sliding components 20 are provided, and the sliding seat 30 is slidably connected to the base 10 through at least two sliding components 20, so its sliding trajectory is more stable and its load-bearing capacity is also greater.

[0065] The drive unit 100 also includes at least two adapters 60 connected to the sliding seat 30. The sliding seat 30 has a communication channel (not shown in the figure) connecting the oil injection port 80 and the at least two adapters 60. The at least two adapters 60 are respectively connected to the oil injection ports 23 of the lubrication structures on the at least two sliding assemblies 20. In this way, the lubricating oil injected by the oil supply device 40 into the oil injection port 80 can flow into the lubrication structures on the at least two sliding assemblies 20, thereby lubricating the slide rails 21 and sliders 22 of the at least two sliding assemblies 20.

[0066] The sliding seat 30 is located on the side of the slider 22 facing away from the base 10. The sliding seat 30 has a through hole 31 corresponding to the oil inlet 23, extending from the side of the sliding seat 30 near the base 10 to the side facing away from the base 10. A pipe (not shown in the figure) connecting the adapter 60 and the oil inlet 23 passes through the through hole 31 to connect to the oil inlet 23. Most of the pipe connecting the adapter 60 and the oil inlet 23 is located on the side of the sliding seat 30 facing away from the base 10, thus optimizing the pipe layout and preventing pipe accumulation in the narrow space between the sliding seat 30 and the base 10. The adapter 60 can be located on the side of the sliding seat 30 facing away from the base.

[0067] Specifically, in this embodiment, the sliding seat 30 is slidably connected to the base 10 via two sliding components 20, and each sliding component 20 includes a slide rail 21 and two sliders 22 connected to the slide rail 21, meaning the sliding seat 30 is connected to four sliders 22. Each slider 22 has a lubrication structure between it and the slide rail 21, and each sliding seat 30 has four adapters 60, each adapter 60 being connected via a pipe to an oil inlet 23 of one of the four lubrication structures.

[0068] In this embodiment, the driving device 100 further includes a second driving member 50, which includes a fixed part 51 connected to the base 10 and an output part 52 connected to the sliding seat 30. When the second driving member 50 is working, the output part 52 moves relative to the fixed part 51, thereby driving the sliding seat 30 to move.

[0069] The second drive unit 50 is a linear motor, the aforementioned fixed part 51 is the stator of the linear motor, and the aforementioned output part 52 is the mover of the linear motor. Linear motors have the advantages of high response speed and high positioning accuracy, making them suitable for applications requiring rapid reciprocating motion, high-precision control, and large-stroke movements.

[0070] The drive device 100 includes at least two second drive members 50, which are respectively disposed on opposite sides of the base 10. Each of the output portions 52 of the at least two second drive members 50 is connected to a sliding seat 30, and each sliding seat 30 is slidably connected to the base 10 via two sliding components 20. The presence of at least two second drive members 50 allows the drive device 100 to drive the sliding seat 30 to move on different sides, enabling the drive device 100 to drive the movement of more devices.

[0071] Specifically, the drive device 100 includes four second drive members 50, which are respectively disposed on opposite sides of the base 10, with two second drive members 50 on each side. The second drive members 50 on the same side are arranged along the length of the base 10. Each of the four second drive members 50 has a sliding seat 30 connected to its output portion 52; therefore, there are also four sliding seats 30. Each sliding seat 30 is connected to the base via two sliding components 20. The four second drive members 50 enable the drive device 100 to drive the four sliding seats 30 to move from different sides, and the four sliding seats 30 can respectively drive four devices to move.

[0072] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0073] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
