Description

Technical Field

[0001] This invention relates to the field of grease gun cup assembly technology, and more particularly to an automatic assembly machine for grease gun cups based on automatic alignment processing. Background Technology

[0002] Grease guns, as specialized tools for lubrication and maintenance of mechanical equipment, play a vital role in many fields such as automobile repair, industrial machinery maintenance, and agricultural machinery maintenance. They can accurately and efficiently apply grease to key moving parts such as bearings, gears, and chains, effectively solving the wear problems caused by insufficient lubrication of these parts, significantly extending the overall service life of the equipment, reducing the failure rate, and ensuring stable operation of the equipment.

[0003] Among them, the rubber cup, as the core sealing element inside the grease gun, is usually carefully made of high-quality elastic materials such as rubber or silicone. Through a tight fit with the inner wall of the gun barrel, it can ensure that the pressure generated when the piston moves is transmitted to the grease without loss during the operation of the grease gun, providing a strong guarantee for the smooth extrusion of grease and realizing stable and efficient grease dispensing operation of the grease gun.

[0004] The assembly of the grease gun cups generally follows the traditional manual assembly method. The pull rod spring is manually placed on the grease gun pull rod, and the pull rod spring is compressed by the user's own strength throughout the process. Then, the plastic parts (equivalent to pistons), the cup and metal gaskets are installed one by one, and finally the pull rod nut is installed to lock it.

[0005] Although it can perform basic assembly of the grease gun cup, the method of manually compressing the lever spring with continuous force throughout the process keeps the body muscles in a tense state for a long time. If the hand strength is slightly reduced, the compressed lever spring will instantly return to its original position and rebound. The strong elastic force is very likely to cause serious injury to the operator's hands, face and other critical parts, resulting in low overall assembly efficiency and poor safety. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic assembly machine for grease gun cups based on automatic alignment processing, in order to solve the aforementioned technical defects.

[0007] The objective of this invention can be achieved through the following technical solution: an automatic assembly machine for grease gun sleeves based on automatic alignment processing, including a fixed base, an industrial robotic arm fixedly mounted on the top of the fixed base, and an adsorption component for layered gripping of multiple parts on the industrial robotic arm;

[0008] The fixed base is provided with a fixing component for graded multi-point clamping of the grease gun lever. The fixing component includes two sets of mirror-arranged clamping blocks, and multiple staggered and inclined V-shaped fixed clamping plates are fixedly connected to the opposite sides of the clamping blocks. The clamping blocks are provided with auxiliary components that cooperate with them to compress the grease gun lever spring.

[0009] Preferably, a stepped platform is fixedly connected to one side of the fixed base, and a conveyor platform 1 is fixedly installed on each of the three steps of different heights of the stepped platform, and a conveyor platform 2 is fixedly installed at the highest point of the top of the stepped platform.

[0010] Preferably, the adsorption assembly includes a mounting base fixedly installed at the end of an industrial robotic arm. Slider blocks are symmetrically slidably connected to both sides of the bottom of the mounting base. Y-shaped air tubes are fixedly connected to the bottom of the sliders and the mounting base via support rods. Multiple vacuum suction cups are installed at the bottom of the Y-shaped air tubes.

[0011] Preferably, a first electric push rod for driving the corresponding slider to move is bolted to the mounting base, a servo motor is bolted to the bottom of the mounting base, and a nut sleeve carrying a magnet is mounted on the output shaft of the servo motor, and the lengths of each support rod are not equal.

[0012] Preferably, the top of the fixed base is fixedly connected to a mounting platform, and a gear is rotatably mounted in the middle of the mounting platform via a pin. The two sides of the mounting platform are symmetrically slidably connected to slide blocks that are fixedly connected to the corresponding clamping blocks. A toothed plate that meshes with the gear is fixedly connected to the slide block. A second electric push rod that pushes the corresponding slide block to move is mounted on the mounting platform via bolts.

[0013] Preferably, a T-shaped plate is slidably connected to the clamping block, and a return spring is fixedly connected between the T-shaped plate and the clamping block. Auxiliary clamping arms are rotatably connected to both sides of the T-shaped plate. A sliding rod is slidably connected to the T-shaped plate, and an arc-shaped clamping plate is fixedly connected to the end of the sliding rod. An elastic plate is fixedly connected between the arc-shaped clamping plate and the auxiliary clamping arm.

[0014] Preferably, the auxiliary component includes a vertical plate slidably connected to the clamping block, and a V-shaped movable clamping plate is obliquely slidably connected to the vertical plate. A universal ball is rolled and embedded in the V-shaped groove of the V-shaped movable clamping plate, and a reset tension spring is fixedly connected between the side of the V-shaped movable clamping plate away from the V-shaped groove and the vertical plate.

[0015] Preferably, the fixed base has a through groove for the corresponding vertical plate to pass through, and L-shaped guide grooves are symmetrically provided on both sides of the through groove. The vertical plate is fixedly connected with a guide pin that is slidably connected to the corresponding L-shaped guide groove.

[0016] The beneficial effects of this invention are as follows:

[0017] The present invention uses a fixed component linked to an auxiliary component and an adsorption component to automate the assembly of the grease gun cup and the pull rod. By cooperating with and linking the V-shaped fixed clamping plates on the two sets of clamping blocks to move in multiple directions with the corresponding V-shaped moving clamping plates, the pull rod of the grease gun is clamped and positioned at multiple points. This ensures the vertical position and replaces the adsorption component to compress the pull rod spring, thus avoiding direct contact between the pull rod spring and the gripped plastic part during assembly.

[0018] On the one hand, it protects the adsorption component and prevents the pull rod spring from bending and deforming due to compression, which could easily cause the plastic part to shift and the vacuum suction cup to deviate, making it difficult to accurately align the hole of the cup component with the pull rod for installation. On the other hand, after assembly, it causes the compressed pull rod spring to slowly and controllably return to its original position and extend, flexibly contacting the plastic part. This avoids the impact that a rapid return of the pull rod spring could cause to the cup component, and it also allows the adsorption component to separate first and then release the compressed pull rod spring, preventing the cup component from clamping the adsorption component and causing damage to the cup and vacuum suction cup during the adsorption component detachment process.

[0019] The fixing component of this invention also has an elastic clamping mechanism for the back cover of the grease gun, which indirectly achieves pre-clamping of the grease gun lever and assists in the rapid installation of the lever spring. By moving the clamping block, the arc-shaped clamping plate contacts the back cover, and the elastic plate, in conjunction with the auxiliary clamping arms, moves relative to each other, so that the arc-shaped clamping plate and the auxiliary clamping arms on both sides jointly perform multi-point centered elastic positioning clamping of the back cover. Furthermore, by deforming and attaching the elastic plate to the back cover, a secondary adaptive wrapping clamping of the back cover is achieved, ensuring the initial centering of the grease gun lever while laying the foundation for the rapid installation of the lever spring.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-6 and Figure 8 As shown, the problems of low assembly efficiency and safety caused by manual assembly in the existing technology can be solved by the following solutions;

[0036] The automatic assembly machine for grease gun cups based on automatic alignment processing in this embodiment includes a fixed base 1, an industrial robotic arm 11 is fixedly installed on the top of the fixed base 1, and an adsorption component 2 for layered gripping of multiple parts is provided on the industrial robotic arm 11.

[0037] The fixed base 1 is provided with a fixing component 3 for multi-point clamping of the grease gun lever in a graded manner. The fixing component 3 includes two sets of clamping blocks 31 arranged in a mirror manner, and multiple staggered and inclined V-shaped fixed clamping plates 32 are fixedly connected to the opposite sides of the clamping blocks 31. The clamping blocks 31 are provided with an auxiliary component 4 that cooperates with them to compress the spring of the grease gun lever.

[0038] By combining the fixing component 3 with the auxiliary component 4, a multi-level step-by-step fixing method is used to achieve stable multi-point clamping of the grease gun pull rod to ensure verticality. Then, with the adsorption component 2, the rubber cup parts are automatically gripped and the spaced holes are aligned, realizing the non-destructive automated assembly of the rubber cup and the pull rod. This avoids the time-consuming and laborious nature of traditional manual installation methods, as well as the problems of low assembly safety.

[0039] A stepped platform 12 is fixedly connected to one side of the fixed base 1, and a conveyor platform 13 is fixedly installed on each of the three steps of the stepped platform 12 at different heights. The conveyor platforms 13 at different heights are used to achieve layered gripping of the cup components (plastic parts, cups and gaskets), laying the foundation for the subsequent alignment of the overlapping holes of the plastic parts, cups and gaskets. The highest conveyor platform 13 is used for gasket conveying, the medium-height conveyor platform 13 is used for cup conveying, and the lowest conveyor platform 13 is used for plastic parts conveying. The conveyor belt on the conveyor platform 13 has a groove in the middle or is equipped with an adapter limit seat for horizontal conveying of plastic parts.

[0040] A second conveyor platform 14 is fixedly installed at the highest point of the stepped platform 12. The second conveyor platform 14 is located above the first conveyor platform 13 at the highest point, and the two overlap on their opposite vertical surfaces. It is used for conveying the tie rod nut and for synchronously gripping the tie rod nut and the washer. Guide plates (not shown in the figure) are provided on both long sides of the first conveyor platform 13 and the second conveyor platform 14, and a limit plate is provided on one short side. It is used for positioning and conveying the plastic parts, the cup, the washer and the tie rod nut, which further lays the foundation for subsequent hole alignment.

[0041] The adsorption assembly 2 includes a mounting base 21 fixedly installed at the end of the industrial robotic arm 11. Slider 22 is symmetrically slidably connected to both sides of the bottom of the mounting base 21. Both the bottom of the slider 22 and the bottom of the mounting base 21 are fixedly connected to Y-shaped air tubes 23 by support rods. Multiple vacuum suction cups 24 are connected to the bottom of the Y-shaped air tubes 23. Through the three sets of Y-shaped air tubes 23 and the multiple vacuum suction cups 24 on the corresponding Y-shaped air tubes 23, the plastic parts of the leather cup component, the leather cup and the gasket are adsorbed and gripped. The movement of the slider 22 is used for the alignment of the holes of the plastic parts, the leather cup and the gasket.

[0042] The mounting base 21 is bolted with a first electric push rod 25 that drives the corresponding slider 22 to move. The bottom of the mounting base 21 is bolted with a servo motor 26, and the output shaft of the servo motor 26 is mounted with a nut sleeve 27 carrying a magnet. The industrial robotic arm 11 drives the fixed base 1 to move above the top of multiple conveyor platforms 13 and 14. Through the Y-shaped air tube 23 and vacuum suction cup 24, it adsorbs and grasps the plastic parts of the leather cup component, the leather cup and the gasket, and magnetically grasps the pull rod nut of the conveyor platform 14 through the nut sleeve 27 carrying the magnet.

[0043] Each support rod has a different length and is used to simultaneously grip and hold plastic parts, leather cups, and gaskets. Two sets of first electric push rods 25 push the corresponding sliders 22 to move, carrying the plastic parts and leather cups to move relative to each other, so that the plastic parts, leather cups, gaskets and the center holes of the pull rod nut are aligned. The industrial robotic arm 11 drives the mounting base 21 to move vertically downward, and puts the plastic parts, leather cups and gaskets with aligned holes onto the pull rod in sequence. At the same time that the pull rod nut contacts the pull rod, the servo motor 26 drives the nut sleeve 27 to rotate, carrying the pull rod nut, to complete the threaded connection between the pull rod nut and the pull rod.

[0044] The top of the fixed base 1 is fixedly connected to the mounting platform 33, and the middle of the mounting platform 33 is rotatably mounted with a gear 34 via a pin. The two sides of the mounting platform 33 are symmetrically slidably connected to the slide blocks 31, and the slide blocks 35 are fixedly connected to the toothed plates 36 that mesh with the gear 34. The mounting platform 33 is bolted with a second electric push rod 37 that pushes the corresponding slide block 35 to move.

[0045] An external robotic arm grasps a grease gun lever equipped with a back cover, safety clip, and handle, and places it vertically between two sets of clamping blocks 31. A second electric push rod 37 pushes the corresponding slide block 35 to move. Another set of slide blocks 35 moves synchronously relative to each other through the meshing of the toothed plate 36 and the gear 34. This causes the two sets of clamping blocks 31 to move relative to each other, carrying staggered V-shaped fixed clamping plates 32. A spring passes through the lever and contacts the lever. The V-shaped groove of the V-shaped fixed clamping plate 32 is used to center and clamp the lever, ensuring the lever's vertical position.

[0046] The auxiliary component 4 includes a vertical plate 41 slidably connected to the clamping block 31, and a V-shaped movable clamping plate 42 is obliquely slidably connected to the vertical plate 41. The clamping block 31 carries the corresponding vertical plate 41 to move synchronously. Compared with the V-shaped fixed clamping plate 32, the V-shaped movable clamping plate 42 on the vertical plate 41 first passes through the pull rod spring and contacts the pull rod, and then combines with the reset pull spring 43 to perform elastic clamping of the upper part of the pull rod.

[0047] When the V-shaped fixed clamping plate 32 clamps the pull rod, the vertical plate 41 and the V-shaped moving clamping plate 42 are in rigid contact to stabilize the upper part of the pull rod. Universal ball bearings are rolled and embedded in the V-shaped groove of the V-shaped moving clamping plate 42 to avoid increasing the sliding resistance between the V-shaped moving clamping plate 42 and the pull rod. A reset spring 43 is fixedly connected between the side of the V-shaped moving clamping plate 42 away from the V-shaped groove and the vertical plate 41.

[0048] The fixed base 1 has a through groove for the corresponding vertical plate 41 to pass through, and L-shaped guide grooves 15 are symmetrically provided on both sides of the through groove. The vertical plate 41 is fixedly connected to the guide pin 44 which is slidably connected to the corresponding L-shaped guide groove 15. During the horizontal movement of the vertical plate 41, the guide pin 44 is guided by the L-shaped guide groove 15, which causes the vertical plate 41 to move the V-shaped moving clamp 42 downward in sync, compressing the pull rod spring between the V-shaped moving clamp 42 and the V-shaped fixed clamp 32, causing the top of the pull rod spring to move below the top of the pull rod.

[0049] The replacement adsorption component 2 uses a compression treatment on the pull rod spring to avoid direct contact between the pull rod spring and the gripped plastic part during assembly. This not only protects the adsorption component 2 but also prevents the pull rod spring from bending and deforming due to compression, which could easily cause the plastic part to shift along with the vacuum suction cup 24, resulting in the problem that the hole of the leather cup component is difficult to align precisely with the pull rod during installation.

[0050] In addition, after assembly, the multiple Y-shaped air tubes 23 no longer adsorb and fix the plastic parts, leather cups and gaskets. The first electric push rod 25 pushes the corresponding slider 22 to reset and move. The industrial robotic arm 11 drives the fixed seat 1 away from the pull rod to grasp the next set of leather cup parts. The plastic parts, leather cups and gaskets naturally adhere and stack under their own weight. The second electric push rod 37 drives the two sets of slides 35 to move away from each other, and simultaneously drives the vertical plate 41 to move away from each other and move upward in sync.

[0051] The compressed pull spring is forced to return to its original position slowly and in a controlled manner, and flexibly contact the plastic parts. This avoids the impact that a rapid return of the pull spring could cause to the diaphragm component. It also ensures that the diaphragm component separates from the adsorption component 2 before releasing the compressed pull spring, thus preventing the diaphragm component from clamping the adsorption component 2. This prevents damage to the diaphragm and vacuum suction cup 24 during the detachment of the adsorption component 2.

[0052] Example 2: Please refer to Figure 5 , Figure 7 As shown, the following solutions can be used to avoid interfering with the installation of the pull rod spring during the clamping process of the grease gun pull rod;

[0053] In this embodiment, a T-shaped plate 38 is slidably connected to the clamping block 31, and a return spring 39 is fixedly connected between the T-shaped plate 38 and the clamping block 31. The two sets of slide blocks 35 move synchronously relative to each other through the meshing of the toothed plate 36 and the gear 34, causing the two sets of clamping blocks 31 to move synchronously relative to each other with the corresponding T-shaped plates 38. The T-shaped plates 38 are used to clamp the back cover of the grease gun, avoiding the problem of interference in the installation of the pull rod spring caused by clamping the pull rod of the grease gun before installation.

[0054] Auxiliary clamping arms 310 are rotatably connected to both sides of the T-shaped plate 38. A sliding rod is slidably connected to the T-shaped plate 38, and an arc-shaped clamping plate 311 is fixedly connected to the end of the sliding rod. An elastic plate 312 is fixedly connected between the arc-shaped clamping plate 311 and the auxiliary clamping arms 310. During the relative movement of the two sets of T-shaped plates 38, the corresponding arc-shaped clamping plate 311 contacts the rear cover on the pull rod. As the T-shaped plate 38 moves and the arc-shaped clamping plate 311 abuts and limits the movement, combined with the elastic plate 312 pulling the auxiliary clamping arms 310 to move relative to each other, and the return spring 39 between the T-shaped plate 38 and the clamping block 31, the arc-shaped clamping plate 311 and the auxiliary clamping arms 310 on both sides perform multi-point centered elastic positioning clamping of the rear cover.

[0055] The back cover is attached by the deformation of the elastic plate 312, and the back cover is wrapped and clamped in a secondary adaptive manner to complete the initial centering of the grease gun pull rod. Then, the pull rod spring is grabbed by an external robotic arm and sleeved on the outside of the pull rod to realize the automatic installation of the pull rod spring.

[0056] Example 3: Please refer to Figures 1-8 As shown, the present invention also proposes a method for using an automatic assembling machine for grease gun sleeves based on automatic alignment processing, including the following steps:

[0057] Step 1: The grease gun lever with a back cover, safety card and handle is grasped by an external robotic arm and placed vertically between two sets of clamping blocks 31, with the handle of the lever touching the top of the mounting platform 33. The second electric push rod 37 pushes the corresponding slide 35 to move. The other set of slides 35 moves synchronously relative to each other through the meshing of the toothed plate 36 and the gear 34, causing the two sets of clamping blocks 31 to move synchronously relative to each other with the corresponding T-shaped plate 38.

[0058] Step 2: During the relative movement of the two sets of T-shaped plates 38, the corresponding arc-shaped clamping plates 311 contact the back cover on the pull rod. As the T-shaped plates 38 move and the arc-shaped clamping plates 311 abut and limit the movement, combined with the elastic plate 312 pulling the auxiliary clamping arms 310 relative to each other, and the return spring 39 between the T-shaped plates 38 and the clamping blocks 31, the arc-shaped clamping plates 311 and the auxiliary clamping arms 310 on both sides perform multi-point centered elastic positioning clamping of the back cover, and the elastic plate 312 deforms and adheres to the back cover, and secondarily adaptably wraps and clamps the back cover, completing the initial centered placement of the grease gun pull rod;

[0059] Step 3: The mechanical arm grabs the pull rod spring again and puts it on the outside of the pull rod. The large diameter end of the pull rod spring contacts the back cover. The second electric push rod 37 continues to push the two sets of clamping blocks 31 to move relative to each other. The multiple staggered V-shaped fixed clamping plates 32 on the two sets of clamping blocks 31 move relative to each other and pass through the pull rod spring to contact the pull rod. Combined with the V-shaped groove of the V-shaped fixed clamping plate 32, the pull rod is centered and clamped for a second time to ensure the vertical state of the pull rod.

[0060] Step 4: During the synchronous movement of the clamping block 31 carrying the corresponding vertical plate 41, the V-shaped moving clamping plate 42 on the vertical plate 41 first passes through the pull rod spring and contacts the pull rod. Then, during the movement of the vertical plate 41, the contact limit of the V-shaped moving clamping plate 42 causes the reset pull spring 43 to be stretched. In addition, the guide pin 44 is guided by the L-shaped guide groove 15, which causes the vertical plate 41 to move the V-shaped moving clamping plate 42 downward synchronously, compressing the pull rod spring between the V-shaped moving clamping plate 42 and the V-shaped fixed clamping plate 32, causing the top of the pull rod spring to move below the top of the pull rod.

[0061] Step 5: During the secondary fixing of the pull rod, the plastic parts, leather cups, and gaskets are synchronously conveyed through multiple conveyor platforms 13 of different heights. The plastic parts, leather cups, and gaskets are conveyed sequentially through the three conveyor platforms 13 from bottom to top. The pull rod nut is conveyed through conveyor platform 24. During the conveying process, the guide plates on both sides of the top of the conveyor platform and the limiting plate at one end are used for centering the conveying. The industrial robotic arm 11 drives the fixed base 1 to move to the top of the multiple conveyor platforms 13 and conveyor platform 24. The plastic parts, leather cups, and gaskets of the leather cup component are adsorbed and gripped through three sets of Y-shaped air pipes 23 of different heights and multiple vacuum suction cups 24 on the corresponding Y-shaped air pipes 23. The pull rod nut of conveyor platform 24 is magnetically gripped by the nut sleeve 27 carrying a magnet.

[0062] Step Six: As the industrial robotic arm 11 moves the gripped plastic part, cup, washer, and pull rod nut to the top of the pull rod, the two sets of first electric push rods 25 push the corresponding sliders 22 to move, carrying the plastic part and cup to move relative to each other, so that the plastic part, cup, washer and the center hole of the pull rod nut are aligned. Then, the mounting base 21 moves vertically downward, and the plastic part, cup, and washer are sequentially put onto the pull rod. At the same time as the pull rod nut contacts the pull rod, the servo motor 26 drives the nut sleeve 27 to rotate, completing the threaded connection between the pull rod nut and the pull rod.

[0063] After the multiple Y-shaped air tubes 23 are removed from adsorbing and fixing the plastic parts, leather cups and gaskets, the first electric push rod 25 pushes the corresponding slider 22 to reset and move, and the industrial robotic arm 11 moves the fixed seat 1 away from the pull rod to grasp the next set of leather cup parts. The plastic parts, leather cups and gaskets naturally adhere and stack under their own weight. Then, the second electric push rod 37 drives the two sets of slides 35 to move away from each other, causing the vertical plate 41 to move away from each other and move upward synchronously. This causes the compressed pull rod spring to slowly reset and extend and flexibly abut against the plastic parts. Then, the clamping of the back cover is released, and the next set of grease gun pull rods is placed and clamped.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
