Description

Technical Field

[0001] This invention relates to the field of technology, specifically to a modular assembly linear guide and its usage method. Background Technology

[0002] With the increasing demand and requirements for precision automation, linear guide technology and its products have become indispensable components in precision automation equipment. A large number of linear guide products of different specifications have also been developed. Although the development of linear guides is rapid, there is still much room for improvement in the quality and cost of linear guides for users who are constantly raising their requirements for product quality. At present, the production of existing standard linear guides requires at least 8 sets of molds for the parts needed to produce dustproof sliders, and the assembly parts can reach 12 parts, which leads to high costs, difficulties in production and assembly, and errors in the fit between multiple parts.

[0003] The existing linear guide rails have the following drawbacks:

[0004] 1. Patent document CN218542938U discloses a multi-rail splicing structure and a modular linear transport platform using the same. The protected claim states that the transport platform includes a machine base, a transport mechanism, and at least one set of linear transport modules mounted on the machine base; the transport mechanism includes a slide table, sliders, and magnets; sliders are mounted on both sides of the slide table, and a magnet is fixed to one side of the slide table; the linear transport modules are mounted on the machine base, and each linear transport module includes a mounting base, a drive module, and a guide rail; the drive module is installed corresponding to the magnet position; the slide table is slidably connected to the guide rail via sliders, and the drive module acts on the magnet. This allows the slide to reciprocate along the linear guide rail. When two linear transport modules are docked, a buffer gap is maintained between the guide rails of each linear transport module. This utility model adopts a modular design to splice multiple linear transport modules. In the multi-module design, the splicing points of the guide rails are designed with a chamfered structure and a splicing gap is maintained to avoid the transport mechanism from derailing or shifting when passing through the splicing points. The purpose is to reduce the production and assembly costs of parts and to prevent oil leakage during the use of linear guide rail products by modifying the circulation system, thus preventing oil pollution of automated equipment.

[0005] 2. Patent document CN103286569A discloses a linear guide rail, and the protected claim "includes a guide rail body, a slider, and a buffer disposed at the left end of the guide rail body; the buffer includes: a cylinder body, a cylinder cover at the open end of the cylinder body, a piston rod passing through the cylinder cover, and a piston body assembly at the right end of the piston rod; the left end of the piston rod is fixedly connected to the left end of the guide rail body; during buffering operation, the right end face of the cylinder body serves as the contact surface that collides with the slider; an electromagnet is disposed in the side wall of the cylinder body, and a pressure sensor is disposed on the right end face of the piston body assembly, the pressure sensor being connected to a processor module; when the slider impacts the right end of the cylinder body, the processor module is adapted to control a current drive module to output a current matching the medium pressure value to attract the slider; until the processor module measures the medium pressure value as an equilibrium value, it controls the current drive module to shut off the output current to release the slider." Most existing devices require manual lubrication by operators, increasing the workload of operators.

[0006] 3. Patent document CN110454499A discloses a linear guide rail, specifically protecting a linear guide rail including a mounting base, guide rail mounting components, a push block, an arc-shaped guide rail mounting plate, a cylindrical guide rail mounting plate, a cylindrical guide rail fixing block, a cylindrical guide rail, a slider, a horizontal plate, a top plate, a vertical plate, a connecting shaft, a positioning bolt, a cleaning mechanism, an arc-shaped bearing, a limit post, an arc-shaped guide rail, an oil pump, an oil tank, a tee pipe, an oil inlet connector, a limit groove, an oil passage, an oil drip hole, a threaded rod, a bearing, a cotton cloth cleaning block, an arc-shaped plate, and a screw. The invention addresses the issue of wear and tear causing wobbling during sliding. In this case, the position of the arc-shaped guide rail can be adjusted by pushing the push block. Once the arc-shaped bearing and the arc-shaped guide rail are in close contact, the slider can operate stably, allowing the device to continue to be used without replacement. This significantly extends the device's lifespan and reduces operating costs. The device includes a cleaning mechanism and a lubrication mechanism, greatly facilitating the cleaning and lubrication of the arc-shaped guide rail surface. Existing devices often fail to clean the guide rail, leading to increased wear and a shortened lifespan. Summary of the Invention

[0007] The purpose of this invention is to provide a modular assembly linear guide and its usage method to solve the problems mentioned in the background art.

[0011] Preferably, the water pump has an inlet pipe installed at its input end, with the bottom of the inlet pipe extending out of the bottom of the fixing plate; an output pipe is installed at the output end of the water pump, with one end of the output pipe extending into the interior of the slider; and a control valve is installed on the outer wall of the output pipe.

[0013] Preferably, a sliding rod is installed at the bottom of the fixed plate, a float is fitted on the outer wall of the sliding rod, a detector is installed at the bottom of the fixed plate and the inner bottom wall of the fixed box, a first switch is installed on the inner bottom wall of the detector, a lifting rod is installed through the top of the detector, an impact plate is installed at the top of the lifting rod, and a second spring is installed around the outer wall of the lifting rod.

[0014] Preferably, the top inner wall of the fixed box is equipped with an intercepting net, and an air pump is installed on the top inner inner wall of the fixed box, with the air pump located inside the intercepting net. A telescopic pipe is installed through the outer wall of the fixed box, and a dust collection head is installed at one end of the telescopic pipe. An inclined plate is installed on the outer wall of the partition plate.

[0015] Preferably, a collection trough is installed through the outer wall of the fixed box, a vertical plate is installed at the bottom of the collection trough, a first wedge rod is installed on the outer wall of the vertical plate, a fixed shaft is installed on the outer wall of the partition plate, a second wedge rod is installed on the outer wall of the fixed shaft, and a third spring is installed on the top of the second wedge rod.

[0016] Preferably, a protective shell is installed on the inner bottom wall of the fixed box, a return spring is installed on the inner bottom wall of the protective shell, a moving rod is installed on the top of the return spring, a rotating shaft is installed on the top of the moving rod, and a roller is installed on the outer wall of the rotating shaft, with the outer wall of the roller in contact with the bottom of the collection tank.

[0017] Preferably, the working steps of the linear guide are as follows:

[0018] S1. By integrating the linear guide retainer and the lower dustproof plate, the original design that required 2 sets of plastic injection molds and 1 set of rubber coating injection molds is optimized into 1 set of plastic injection molds and 1 set of rubber coating injection molds. At the same time, the structure of the end cap plastic injection is modified so that the slider can achieve the structure of preventing oil leakage without adding parts or additional processing. The number of slider assembly parts is reduced from 11 parts to 9 parts, improving the assembly time by about 20%.

[0019] S2. When lubricating the inside of the slider, pull the pull ring to remove the sealing plug, pour the lubricating oil into the oil inlet pipe, the water pump works, and the lubricating oil is drawn out through the water inlet pipe. Then the motor rotates and drives the take-up shaft to rotate. The take-up shaft pulls the sealing plate to move, so that the sealing plate is separated from the sealing groove. The lubricating oil flows out from the output end of the water pump and enters the inside of the slider to achieve the lubrication function of the slider.

[0020] S3. When cleaning the slide rail, move the telescopic tube and dust collection head to the top of the slide rail. Then the air pump works to extract the air from the inside of the fixed box. The inside of the fixed box is under negative pressure. The telescopic tube and dust collection head suck in the air and draw the dust on the slide rail into the inside of the fixed box to achieve the dust removal function.

[0021] Preferably, step S1 further includes the following steps;

[0022] S11. Integrating the retainer and the lower dustproof accessory into one accessory can directly reduce the cost of a set of molds. When assembling the slider, the process of assembling the lower dustproof sheet can be eliminated, and the lower dustproof sheet can be prevented from falling off during product use. By changing the structure of the end cap and adding an oil leakage prevention ring, without adding any parts, when the end cap and slider are locked, the oil leakage prevention ring is compressed so that its shape fits the uneven surface of the slider, thereby preventing lubricating oil from overflowing from this point.

[0023] The S2 process also includes the following steps;

[0024] S21. When the lubricating oil content decreases or becomes full, the float slides on the slide bar and contacts the impact plate, causing the lifting rod to move. The movement of the lifting rod causes the second spring to extend, and the lifting rod contacts the first switch, which is displayed on the screen.

[0025] The S3 also includes the following steps;

[0026] S31. Dust accumulates inside the collection tank. When the collection tank is full, the weight of the collection tank increases, squeezing the roller downwards. The roller drives the rotating shaft and moving rod to descend. The collection tank drives the vertical plate and the first wedge rod to descend. The second wedge rod disengages from the first wedge rod. At this time, the collection tank can be removed. After cleaning the collection tank, insert the collection tank into the inside of the fixed box. The first wedge rod contacts the second wedge rod. The second wedge rod rotates, causing the third spring to contract.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention utilizes an integrated linear guide retainer and a lower dustproof sheet to optimize the original design, which required two sets of plastic injection molds and one set of rubber-coated injection molds, into one set of plastic injection molds and one set of rubber-coated injection molds. At the same time, the structure of the end cap plastic injection is modified so that the slider can achieve an oil-leakage-proof structure without the need for additional parts or extra processing. The number of slider assembly parts is reduced from 11 to 9, improving assembly time by approximately 20%.

[0029] 2. This invention achieves lubrication by installing a water pump. When lubricating the inside of the slider, pull the pull ring to remove the sealing plug, pour the lubricating oil into the oil inlet pipe, the water pump works, and draws out the lubricating oil through the water inlet pipe. Then the motor rotates and drives the take-up shaft to rotate. The take-up shaft pulls the sealing plate to move, so that the sealing plate separates from the sealing groove. The lubricating oil flows out from the output end of the water pump and enters the inside of the slider, thus achieving the lubrication function of the slider.

[0030] 3. This invention can achieve dust removal function by installing a dust collection head. When removing dust from the slide rail, the telescopic tube and the dust collection head are moved to the top of the slide rail. Then the air pump works to extract the air inside the fixed box. The internal negative pressure of the fixed box causes the telescopic tube and the dust collection head to draw in air, sucking the dust on the slide rail into the interior of the fixed box, thus achieving the dust removal function.

[0047] The working steps of this linear guide are as follows:

[0048] S1. By integrating the linear guide retainer and the lower dustproof plate, the original design that required 2 sets of plastic injection molds and 1 set of rubber coating injection molds is optimized into 1 set of plastic injection molds and 1 set of rubber coating injection molds. At the same time, the structure of the end cap plastic injection is modified so that the slider can achieve the structure of preventing oil leakage without adding parts or additional processing. The number of slider assembly parts is reduced from 11 parts to 9 parts, improving the assembly time by about 20%.

[0049] S2. When lubricating the inside of the slider 6, pull the pull ring 15 to remove the sealing plug 14, pour the lubricating oil into the oil inlet pipe 13, the water pump 17 works, and draws out the lubricating oil through the water inlet pipe 18. Then the motor 23 rotates and drives the take-up shaft to rotate. The take-up shaft pulls the sealing plate 21 to move, so that the sealing plate 21 separates from the sealing groove 20. The lubricating oil flows out from the output end of the water pump 17 and enters the inside of the slider 6 to achieve the lubrication function of the slider 6.

[0050] S3. When cleaning the slide rail, move the telescopic tube 33 and the dust collection head 34 to the top of the slide rail. Then the air pump 32 works to extract the air inside the fixed box 9. The fixed box 9 is under negative pressure. The telescopic tube 33 and the dust collection head 34 suck in the air and draw the dust on the slide rail into the fixed box 9 to achieve the dust removal function.

[0051] The steps in S1 also include the following:

[0052] S11. Integrating the retainer and the lower dustproof accessory into one accessory can directly reduce the cost of a set of molds. When assembling the slider, the process of assembling the lower dustproof sheet can be eliminated, and the lower dustproof sheet can be prevented from falling off during product use. By changing the structure of the end cap and adding an oil leakage prevention ring, without adding any parts, when the end cap and slider are locked, the oil leakage prevention ring is compressed so that its shape fits the uneven surface of the slider, thereby preventing lubricating oil from overflowing from this point.

[0053] The S2 process also includes the following steps;

[0054] S21. When the lubricating oil content decreases or becomes full, the float 25 slides on the slide bar 24 and contacts the impact plate 29, causing the lifting rod 28 to move. The movement of the lifting rod 28 causes the second spring 30 to extend, and the lifting rod 28 contacts the first switch 27, which is displayed on the display screen 10.

[0055] The S3 also includes the following steps;

[0056] S31. Dust accumulates inside the collection trough 36. When the collection trough 36 is full, its weight increases, pressing down on the roller 46. The roller 46 drives the rotating shaft 45 and the moving rod 44 to descend. The collection trough 36 drives the vertical plate 37 and the first wedge rod 38 to descend. The second wedge rod 40 disengages from the first wedge rod 38. At this time, the collection trough 36 can be removed. After cleaning the collection trough 36, it is inserted into the fixed box 9. The first wedge rod 38 contacts the second wedge rod 40. The second wedge rod 40 rotates, causing the third spring 41 to contract.

[0057] The working principle utilizes an integrated linear guide retainer and a lower dustproof plate to optimize the original design, which required two sets of plastic injection molds and one set of rubber-coated injection molds, into one set of plastic injection molds and one set of rubber-coated injection molds. At the same time, the structure of the end cap plastic injection is modified so that the slider can achieve an oil-leakage-proof structure without the need for additional parts or processing. The number of slider assembly parts is reduced from 11 to 9, improving assembly time by about 20%. Integrating the retainer and lower dustproof components into one component directly reduces the cost of one set of molds. During slider assembly, the step of assembling the lower dustproof plate can be eliminated, and the lower dustproof plate can be prevented from falling off during product use. The end cap structure is modified to add an oil-leakage-proof ring. Without adding any parts, when the end cap and slider are locked, the oil-leakage-proof ring is compressed so that its shape fits the uneven surface of the slider, thus preventing lubricating oil from overflowing from this point.

[0058] When lubricating the inside of slider 6, pull ring 15 to remove sealing plug 14, pour lubricating oil into oil inlet pipe 13, water pump 17 works, and draws out lubricating oil through water inlet pipe 18. Then motor 23 rotates to drive take-up shaft to rotate, and take-up shaft pulls sealing plate 21 to move, so that sealing plate 21 separates from sealing groove 20. Lubricating oil flows out from the output end of water pump 17 and enters the inside of slider 6 to achieve the lubrication function of slider 6. When the lubricating oil content decreases or fills up, float 25 slides on slide rod 24. Float 25 contacts impact plate 29, causing lifting rod 28 to move. The movement of lifting rod 28 causes second spring 30 to extend. Lifting rod 28 contacts first switch 27 and is displayed on display screen 10.

[0059] When cleaning the slide rail, the telescopic tube 33 and dust collection head 34 are moved to the top of the slide rail. Then, the air pump 32 works to extract the air from the inside of the fixed box 9, creating a negative pressure inside the fixed box 9. The telescopic tube 33 and dust collection head 34 draw in air, sucking the dust on the slide rail into the inside of the fixed box 9, thus achieving the dust removal function. The dust accumulates inside the collection trough 36. When the collection trough 36 is full, the weight of the collection trough 36 increases, squeezing the roller 46 downward. The roller 46 drives the rotating shaft 45 and the moving rod 44 to descend. The collection trough 36 drives the vertical plate 37 and the first wedge rod 38 to descend. The second wedge rod 40 disengages from the first wedge rod 38. At this time, the collection trough 36 can be removed. After cleaning the collection trough 36, it is inserted into the inside of the fixed box 9. The first wedge rod 38 contacts the second wedge rod 40. The second wedge rod 40 rotates, causing the third spring 41 to contract.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

7. The method of using a modularly assembled linear guide rail according to claim 6, characterized in that, The working steps of this linear guide are as follows: S1. Integrating the retainer and the lower dustproof accessory into one accessory can directly reduce the cost of a set of molds. When assembling the slider, the process of assembling the lower dustproof sheet can be eliminated, and the lower dustproof sheet can be prevented from falling off during product use. By changing the structure of the end cap and adding an oil leakage prevention ring, without adding any parts, when the end cap and slider are locked, the oil leakage prevention ring is compressed so that its shape fits the uneven surface of the slider, thereby preventing lubricating oil from overflowing from this point. S2. When lubricating the inside of the slider (6), pull the pull ring (15) to remove the sealing plug (14), pour the lubricating oil into the oil inlet pipe (13), the water pump (17) works, and the lubricating oil is drawn out through the water inlet pipe (18). Then the motor (23) rotates and drives the take-up shaft to rotate. The take-up shaft pulls the sealing plate (21) to move, so that the sealing plate (21) is separated from the sealing groove (20). The lubricating oil flows out from the output end of the water pump (17) and enters the inside of the slider (6) to realize the lubrication function of the slider (6). S3. When cleaning the slide rail, move the telescopic tube (33) and dust collection head (34) to the top of the slide rail. Then the air pump (32) works to extract the air inside the fixed box (9). The fixed box (9) is under negative pressure. The telescopic tube (33) and dust collection head (34) suck in the air and suck the dust on the slide rail into the fixed box (9) to achieve the dust removal function.

8. A modular assembly linear guide rail and its usage method according to claim 7, characterized in that, The S2 process also includes the following steps; S21. When the lubricating oil content decreases or becomes full, the float (25) slides on the slide bar (24), the float (25) contacts the impact plate (29), causing the lifting rod (28) to move. The movement of the lifting rod (28) drives the second spring (30) to extend, and the lifting rod (28) contacts the first switch (27), which is displayed on the display screen (10). The S3 also includes the following steps; S31. Dust accumulates inside the collection trough (36). When the collection trough (36) is full, the weight of the collection trough (36) increases, squeezing the roller (46) downward. The roller (46) drives the rotating shaft (45) and the moving rod (44) to descend. The collection trough (36) drives the vertical plate (37) and the first wedge rod (38) to descend. The second wedge rod (40) separates from the first wedge rod (38). At this time, the collection trough (36) can be taken out. After cleaning the collection trough (36), the collection trough (36) is inserted into the inside of the fixed box (9). The first wedge rod (38) contacts the second wedge rod (40). The second wedge rod (40) rotates, causing the third spring (41) to contract.
