Description

Technical Field

[0001] This utility model belongs to the field of slide rail technology, and in particular relates to a slider lubrication structure, a spindle assembly, and PCB processing equipment. Background Technology

[0002] Multiple spindles are arranged along the X-direction on the crossbeam of the PCB drilling machine. The spindle base plate is connected to the crossbeam by sliders and guide rails. Two sliders are installed on the spindle base plate, and the sliders cooperate with the guide rails on the crossbeam to allow the spindle to move smoothly along the X-direction.

[0003] Currently, lubrication mechanisms are typically located on the side of the slider. To enable two or more spindles to process a single PCB simultaneously and accommodate a wider range of PCB sizes, the spindle spacing needs to be minimized. Conversely, to ensure the stability of the spindle's movement along the guide rail via the slider, the distance between the two sliders on the X-axis should be as large as possible. This contradiction leads to a situation in the current design where, with a fixed spindle spacing, the lubrication mechanism on the side of the slider may collide, potentially damaging it and causing lubrication failure between the slider and the guide rail. This, in turn, affects the smoothness and accuracy of the spindle movement. Utility Model Content

[0035] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] like Figures 1 to 4 As shown, an embodiment of this utility model provides a slide rail 2 for sliding cooperation with a PCB processing equipment 500. The slide rail 2 extends along a first direction a. The slider lubrication structure 100 includes a slider 1 and an injection nozzle 3. The slider 1 is slidably connected to the slide rail 2. By sliding the slider 1 on the slide rail 2, the spindle assembly 300 can be driven to reciprocate along the first direction a, so that during the PCB processing process of the PCB processing equipment 500, the spindle assembly 300 can move quickly and accurately to different positions to process the target positions on the PCB.

[0037] The slider 1 has a first end face 15 and a second end face 16 arranged opposite to each other along the first direction a. The slider 1 is provided with a liquid injection hole 111 and a liquid injection channel 14, which are connected. The liquid injection hole 111 is located between the first end face 15 and the second end face 16. The liquid injection nozzle 3 is located between the first end face 15 and the second end face 16. The liquid injection nozzle 3 is used to guide the lubricant into the liquid injection hole 111. The liquid injection channel 14 can guide the lubricant to the junction of the slider 1 and the slide rail 2.

[0038] Specifically, the first end face 15 and the second end face 16 are arranged opposite to each other in the first direction a. The slider has end caps at both ends; the first end face 15 is the end face of one of the end caps, and the second end face 16 is the end face of the other end cap. The injection hole 111 is located between the first end face 15 and the second end face 16. That is, the injection hole 111 is not located on the end caps of the slider 1, so that the position of the injection nozzle 3 avoids the side of the slider 1 (i.e., the first end face 15 and the second end face 16), an area prone to collision. When adjacent spindle assemblies 300 move, this reduces the risk of collision between the slider lubrication structures 100 of different spindle assemblies 300, ensuring the lubrication effect of the slider lubrication structure 100 on the slider 1 and the slide rail 2.

[0039] In this embodiment, the outlet of the injection nozzle 3, the injection hole 111, and the injection channel 14 are connected in sequence. Lubricating fluid is injected through the injection nozzle 3. The lubricating fluid flows through the injection hole 111 and the injection channel 14 in sequence and reaches the junction of the slider 1 and the slide rail 2. As the slider 1 moves on the slide rail 2, the lubricating fluid is coated on the slide rail 2 to form a lubricating film, which significantly reduces the coefficient of friction between the two, reduces the wear between the slider 1 and the slide rail 2, avoids possible jamming or slight jumping during the movement of the slider 1, makes the movement of the spindle assembly more stable, reduces the positional deviation of the spindle 301 of the spindle assembly 300, and greatly improves the accuracy of PCB processing.

[0040] It should be noted that the injection nozzle 3 has a hollow channel 31 inside. The injection nozzle 3 is connected to an external liquid supply device, so that the lubricating fluid passes through the hollow channel 31 and the injection channel 14 of the injection nozzle 3 to achieve lubrication. The lubricating fluid is lubricating oil.

[0041] In one embodiment, the slider 1 is mounted on the base plate 40 of the spindle assembly 300 of the PCB processing equipment 500. By sliding the slider 1 on the slide rail 2, the spindle assembly 300 can reciprocate along the first direction a.

[0042] The injection hole 111 is located on the side of the slider 1 facing the base plate 400. The opening of the injection hole 111 faces the base plate 400, avoiding the side of the slider 1, which is prone to collision, and at the same time facilitating the setting of the injection channel inside the slider.

[0043] In one embodiment, such as Figure 1 As shown, one end of the injection nozzle 3 is disposed in the injection hole 111, and the other end of the injection nozzle 3 is connected to the liquid supply device. The lubricant can directly enter the injection hole 111 and the injection channel 14 to lubricate the slider 1 and the slide rail 2. By placing the injection nozzle 3 in the injection hole 111, a compact layout can be achieved, reducing the external space occupied by the slider lubrication structure 100.

[0044] In one embodiment, such as Figure 1 As shown, a through hole 401 is provided on the base plate 400. One end of the injection nozzle 3 is disposed in the injection hole 111, and the other end of the injection nozzle 3 protrudes from the through hole 401 on the base plate 400 and connects to the fluid supply device. By providing a through hole 401 on the base plate 400, the base plate 400 does not interfere with the injection nozzle 3, and the operator can directly contact the injection nozzle 3 through the through hole 401 without disassembling the spindle assembly 300, which facilitates maintenance and inspection. At the same time, the through hole 401 reduces the opportunity for the injection nozzle 3 to come into contact with the external environment, reducing the possibility of impurities entering the lubrication structure, thereby ensuring the cleanliness and lubrication effect of the lubricating fluid.

[0045] In one embodiment, such as Figure 2 As shown, the slider lubrication structure 100 also includes an extension rod 4. One end of the extension rod 4 is disposed in the injection hole 111, and the other end of the extension rod 4 passes through the through hole 401 of the base plate 400 and is connected to the injection nozzle 3.

[0046] The extension rod 4 has a connecting channel 41 inside, which runs through the extension rod 4 along its length. The injection nozzle 3 is connected to the injection hole 111 through the connecting channel 41, allowing lubricant to flow out through the injection nozzle 3, pass through the connecting channel 41, the injection hole 111, and the injection channel 14 in sequence, and reach the junction of the slider 1 and the slide rail 2 for lubrication. One end of the injection nozzle 3 is located inside the connecting channel 41.

[0047] By using the extension rod 4, the position of the injection nozzle 3 can be extended from near the injection hole 111 to a more suitable place, avoiding spatial conflict between the injection nozzle 3 and other components, making it convenient for maintenance personnel to perform injection operations, and improving the application scenarios of the slider lubrication structure 100.

[0048] In one embodiment, such as Figure 2 As shown, the extension rod 4 includes a first rod body 42 and a second rod body 43. The cross-sectional area of ​​the first rod body 42 is smaller than that of the second rod body 43. The first rod body 42 is located in the injection hole 111. The difference in cross-sectional area between the first rod body 42 and the second rod body 43 can limit the position of the extension rod 4 inserted into the injection hole 111.

[0049] In one embodiment, such as Figure 3As shown, the slider lubrication structure 100 also includes a connecting hose 6. One end of the connecting hose 6 is disposed in the injection hole 111, and the other end of the connecting hose 6 passes through the through hole 401 of the base plate 400 and is connected to the injection nozzle 3. The connecting hose 6 can change the flow direction of the lubricant, making it better suited to the spatial layout near the spindle 301 of the PCB processing equipment 500. It can extend the position of the injection nozzle 3 from near the injection hole 111 to a more suitable location, facilitating the connection between the injection nozzle 3 and the connecting hose 6. The material of the connecting hose 6 is usually chosen to be oil-resistant, wear-resistant, and flexible, such as rubber hoses or polyurethane hoses.

[0050] Furthermore, the other end of the connecting hose 6 is connected to the injection nozzle 3 via an adapter 5. Since the connecting hose 6 and the injection nozzle 3 may have different sizes, shapes, or connection methods, the adapter 5 can effectively connect the connecting hose 6 and the injection nozzle 3 together, making the entire slider lubrication structure 100 adaptable to various types of injection nozzles 3, thus improving the versatility of the slider lubrication structure 100.

[0051] In one embodiment, such as Figure 3 As shown, the connecting hose 6 includes a tube body 61, a first connector 62 and a second connector 63. The tube body 61 is connected between the first connector 62 and the second connector 63. The first connector 62 is disposed in the injection hole 111, and the second connector 63 is connected to the injection nozzle 3 through an adapter 5.

[0052] In one embodiment, the injection channel 14 has an inlet end 14a and an outlet end 14b. The inlet end 14a is connected to the injection hole 111. The outlet end 14b is located at the junction of the slider 1 and the slide rail 2, allowing lubricant to be directly guided to this junction for lubrication. In other alternative embodiments, a guide pipe or channel can be provided between the outlet end 14b and the junction of the slider 1 and the slide rail 2, which also achieves lubrication during the relative movement of the slider 1 and the slide rail 2.

[0053] In one embodiment, the slider 1 includes a slider body 11, a first contact portion 12, and a second contact portion 13. The first contact portion 12 and the second contact portion 13 are disposed opposite each other on the slider body 11 along a second direction b. The first direction a and the second direction b are not parallel and do not coincide. The first contact portion 12 and the second contact portion 13 can fit against the slide rail 2. The injection hole 111 and the inlet end 14a are both disposed on the slider body 11, facilitating the installation of the injection nozzle 3. Compared with the existing method of placing the lubrication structure on the end cap of the slider 1, in this embodiment, regardless of how the spacing between the two spindle assemblies 300 is adjusted, the injection nozzles 3 of the slider lubrication structures 100 of adjacent two spindle assemblies 300 will not collide. Preferably, the first direction a and the second direction b are perpendicular.

[0054] The inner contour of the first contact portion 12 is geometrically matched with the outer contour of one side of the slide rail 2. The inner contour of the second contact portion 13 is geometrically matched with the outer contour of the other side of the slide rail 2 to ensure that the slider 1 and the slide rail 2 fit tightly together and provide good guidance.

[0055] In one embodiment, both the injection hole 111 and the inlet end 14a are located in the middle of the slider body 11, so that the lubricant diffuses and flows from the middle of the slider body 11 to the first contact portion 12 and the second contact portion 13 on both sides, reducing the uneven flow of lubricant during initial distribution due to the bias of the inlet position, and ensuring the consistency of lubrication effect.

[0056] In one embodiment, the injection hole 111 extends along a third direction c. The first direction a, the second direction b, and the third direction c are not parallel to each other and do not coincide. The size of the injection hole 111 in the third direction c is smaller than the size of the slider body 11 in the third direction c, that is, the injection hole 111 is a blind hole (the injection hole 111 does not completely penetrate the slider 1 in the third direction c), which facilitates the flow of lubricant in the injection hole 111 to the junction of the slider 1 and the slide rail 2 through the injection channel 14. Preferably, the first direction a, the second direction b, and the third direction c are perpendicular to each other, in which case the opening direction of the injection hole 111 is perpendicular to the first direction a.

[0057] In one embodiment, such as Figures 1 to 3 As shown, the injection channel 14 includes a first channel 141 and a second channel 142. The inlet end 14a of the first channel 141 is connected to the injection hole 111, and the outlet end 14b of the first channel 141 is located at the junction of the first contact part 12 and the slide rail 2.

[0058] The inlet end 14a of the second channel 142 connects to the injection hole 111, and the outlet end 14b of the second channel 142 is located at the junction of the second contact part 13 and the slide rail 2. During the movement of the slider 1, both the first contact part 12 and the second contact part 13 will generate friction with the slide rail 2. The first channel 141 delivers lubricant to the junction of the first contact part 12 and the slide rail 2, and the second channel 142 delivers lubricant to the junction of the second contact part 13 and the slide rail 2, ensuring that both friction areas of the slider 1 and the slide rail 2 can be effectively lubricated, thus improving lubrication efficiency.

[0059] The number of first channels 141 can be one, two or more, and the number of second channels 142 can be one, two or more.

[0060] When there is only one first channel 141 and one second channel 142, both first channel 141 and second channel 142 are directly connected to the injection hole 111. When there are two or more first channels 141 and second channels 142, all first channels 141 are arranged side by side along the first direction a, and all second channels 142 are arranged side by side along the first direction a. The distribution of lubricant can be achieved by setting a main channel extending along the first direction a, which connects all first channels 141 and all second channels 142 respectively.

[0061] On the other hand, such as Figure 5 As shown, this utility model embodiment provides a spindle assembly 300, including a spindle 301, a base plate 400, and a slider lubrication structure 100 as described in the above embodiment. The spindle 301 is mounted on the base plate 400 and is used to process a PCB placed on a worktable. The slider 1 is mounted on the side of the base plate 400 away from the spindle 301. The base plate 400 can move along the slide rail 2 via the slider 1, thereby realizing the reciprocating movement of the spindle 301 relative to the slide rail 2 in the first direction a.

[0062] The injection hole 111 of the slider 1 is located between the first end face 15 and the second end face 16. The opening of the injection hole 111 faces the base plate 400. When two or more spindles 301 are processed on the same PCB, the distance between two adjacent spindles 301 is minimized as much as possible. The adjacent slider lubrication structures 100 will not collide, thus avoiding damage to the lubrication mechanism and causing the spindle 301 to jam, and ensuring the movement accuracy of the spindle 301.

[0063] In one embodiment, multiple slider lubrication structures 100 are provided. The multiple slider lubrication structures 100 are spaced apart on the slide rail 2 along the first direction a and connected to the base plate 400. Each slider 1 is provided with an injection hole 111 and an injection channel 14. Lubricating fluid is injected into the slider 1 through the injection nozzle 3 to further ensure the lubrication effect between the slider 1 and the slide rail 2.

[0064] On the other hand, such as Figure 5 As shown, this utility model embodiment provides a PCB processing equipment 500, including a slide rail 2, a frame 200, and a spindle assembly 300 as described in the above embodiment. The slide rail 2 is mounted on the frame 200, and the slider 1 of the spindle assembly 300 slides in cooperation with the slide rail 2, so that the spindle assembly 300 can move along the first direction a on the slide rail 2 via the slider 1. The adjacent slider lubrication structures 100 will not collide, avoiding damage to the lubrication mechanism and causing the spindle 301 to jam. This can improve the movement accuracy of the spindle 301 along the first direction a on the frame 200.

[0065] Furthermore, the PCB processing equipment 500 also includes a worktable mounted on the frame 200. The material board is placed on the worktable, and the spindle assembly 300 can process the material board.

[0066] In one embodiment, multiple spindle assemblies 300 are provided, and the multiple spindle assemblies 300 are spaced apart along a first direction a, and at least two adjacent spindle assemblies 300 can process the same PCB.

[0067] By setting the injection hole 111 on the slider 1, and the injection hole 111 being located between the first end face 15 and the second end face 16 of the slider 1, the injection nozzle 3 avoids both sides of the slider 1 along the first direction a. This ensures that when the spacing between two adjacent spindle assemblies 300 is adjusted, the injection nozzle 3 will not occupy the space in the first direction a, thereby minimizing the spacing between the two spindle assemblies 300 and increasing the applicability of the PCB.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
