Description

Technical Field

[0001] The embodiments of this utility model belong to the technical field of magnetic snap assembly equipment, and more specifically, relate to a semi-automatic assembly equipment suitable for magnetic snaps. Background Technology

[0002] Magnets, as an indispensable magnetic material in manufacturing, are widely used in the electronics and electrical appliance manufacturing industries for the assembly of electronic components. Currently, magnet assembly is mostly done manually. During the operation, workers rely entirely on their hand strength to directly pick up the magnet clips, align them with the product component mounting positions, and manually press them in. The entire process from picking up and positioning to assembly is completed by relying on human experience and manual operation.

[0003] This purely manual assembly method, while adaptable to product components and magnetic clasps with large differences in shape and specifications and requiring no initial equipment investment, has obvious limitations: First, efficiency is constrained by the physical strength and skill level of workers, making it difficult to cope with large-scale production and batch operations taking a long time; second, the pressure and angle applied manually are unstable, which can easily lead to improper installation, misalignment, or even damage to components, resulting in poor product quality consistency; third, workers are prone to fatigue and strain injuries from repetitive operations over long periods of time, posing occupational health hazards and further affecting assembly quality.

[0004] Therefore, there is an urgent need for a magnetic snap assembly equipment that can automatically position and assemble magnets, improve work efficiency, reduce possible offsets during manual alignment, and enhance the accuracy of magnet assembly. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages 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 only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figure 1-7 As shown, this utility model provides a semi-automatic assembly device suitable for magnetic snap fasteners, including a base 1, a sliding support 2, a drive mechanism 3, a magnetic feed column 4, a magnet positioning assembly 5, and a round nail positioning plate 6. The sliding support 2 and drive mechanism 3 are fixedly mounted on the left and right ends of the top of the base 1, respectively. The top of the sliding support 2 has a groove 202 for limiting the sliding of the magnet 8, and the depth of the groove 202 is the same as the height of the magnet 8. The drive mechanism 3 includes a horizontally arranged cylinder 31, which pushes the magnet 8 to move horizontally. The magnetic feed column 4 is vertically fixed at the top right end of the groove 202, and has a feed cavity 42 for loading the magnet 8. The magnet positioning assembly 5 includes a fixed positioning plate 51 fixed in the groove 202 and a movable push plate 52 fixed at the front end of the piston rod 312. The round nail positioning plate 6 is fixed at the middle of the top of the groove 202, and has a positioning hole 602 with an annular step 603 inside. During operation, the round nail 7 is placed in the positioning hole 602. The drive mechanism 3 moves the movable push plate 52 forward, thereby pushing the magnet 8 along the slide groove 202 until the other end of the magnet 8 contacts the fixed positioning plate 51. At this time, the magnet 8 is located directly below the annular step 603. Under the magnetic attraction, it passes through the annular step 603 and is magnetically fixed to the bottom of the round nail 7, completing the automatic assembly operation. This semi-automatic assembly equipment can realize the automatic positioning and assembly of magnets, improve work efficiency, reduce the possible offset during manual alignment, and improve the accuracy of magnet assembly.

[0037] like Figure 1-2 As shown in the embodiment of this utility model, the base 1 is an L-shaped plate structure, including a horizontally arranged base plate 11 and a cylinder fixing plate 12 vertically arranged at the right end of the base plate 11; the base plate 11 and the cylinder fixing plate 12 have corresponding countersunk holes, and the sliding support 2 can be fixed to the top left end of the base 1 by bolts passing through the corresponding countersunk holes on the base plate 11 and threadedly connected to the bottom of the sliding support 2; the cylinder 31 can be horizontally fixed to the top right end of the base 1 by bolts passing through the corresponding countersunk holes on the cylinder fixing plate 12.

[0038] The sliding support 2 is used for the sliding positioning of the magnet 8, and includes a support body 201, a sliding groove 202, a first positioning step 203, and a fixing hole 204. The support body 201 is a cuboid component with a threaded hole at the bottom, which is fixed to the top left end of the base 1 by threaded connection with a bolt. The sliding groove 202 is opened at the top of the support body 201, and its groove depth is the same as the height of the magnet 8, and its groove width is the same as the outer diameter of the annular magnet 8, thereby restricting the linear displacement of the magnet 8 along the sliding groove 202. The first positioning step 203 is located at the top left end of the side wall of the sliding groove 202 and is used to position the round nail positioning plate 6. The fixing hole 204 is located at the bottom left end of the sliding groove 202. The fixing plate 51 is fixed to the bottom of the sliding groove 202 by threaded connection of a bolt through the fixing positioning plate 51 and the fixing hole 204.

[0039] The drive mechanism 3 is used to push the magnet 8 to the assembly point for automatic assembly. It includes a cylinder 31, a manual air supply switch 32, and a solenoid valve 33. The cylinder 31 is horizontally fixed at the top right end of the base 1. It includes a cylinder body 311, a piston rod 312, and a sleeve 313. The cylinder body 311 drives the piston rod 312 to reciprocate leftward in the horizontal direction. The sleeve 313 is fixed at the front end of the piston rod 312. Its other end is provided with a clamping port in the horizontal direction. The clamping port clamps and fixes a movable push plate 52. The manual air supply switch is communicatively connected to the solenoid valve 33 and controls the solenoid valve 33 to introduce air into the cylinder 31 to provide power.

[0040] The magnetic feeding column 4 is used to store magnets 8 and automatically feed them. It includes a column body 41 and a feeding cavity 42. The column body 41 is a square column, which is vertically arranged at the top right end of the side wall of the slide 202. The feeding cavity 42 is arranged vertically inside the column body 41, located directly above the slide 202. It is a cylindrical cavity with an inner diameter that is the same as the outer diameter of the annular magnet 8, thereby limiting the radial displacement of the annular magnet 8 and allowing the magnet 8 to fall straight down into the slide 202 under gravity. Preferably, the bottom left end of the column body 41 is also provided with a second positioning step 43. The height of the second positioning step 43 is the same as the thickness of the round nail positioning plate, which facilitates the positioning of the column body 41.

[0041] The magnet positioning assembly 5 is used to position the magnet 8 at its installation position. It includes a fixed positioning plate 51 and a movable push plate 52. The fixed positioning plate 51 is fixed to the left end of the bottom of the slide groove 202. Its right end has a first arc-shaped part, the thickness of which does not exceed the depth of the slide groove 202. It is adapted to the outer ring of the magnet 8 and restricts the magnet 8 from moving to the left by contact. The right end of the movable push plate 52 is located in the clamping port at the left end of the sleeve 313 and is fixed with bolts to make it fixedly connected to the sleeve 313. The left end of the movable push plate 52 has a second arc-shaped part, the thickness of which does not exceed the depth of the slide groove 202. It is adapted to the outer ring of the magnet 8. The movable push plate 52 is pushed by the piston rod 312, so that the movable push plate 52 drives the magnet 8 to move linearly to the left along the slide groove 202 until it contacts the first arc-shaped part of the fixed positioning plate 51 and stops moving. This places the magnet 8 directly below the round nail 7, and the automatic assembly is completed by magnetic attraction.

[0042] The round nail positioning plate 6 is used to position and install the round nail 7 and limit the adsorption position of the magnet 8. It includes a positioning plate body 601, a positioning hole 602, and an annular step portion 603. The positioning plate body 601 is fixedly disposed at the top center of the side wall of the slide groove 202, with its left end contacting the first positioning step portion 203 and its right end contacting the second positioning step portion 43. The positioning hole 602 is formed on the positioning plate body 601, and its diameter is the same as the outer diameter of the round nail 7. The annular step portion 603 is disposed within the positioning hole 602. With the central axis aligned, the inner diameter of the annular step 603 is the same as the outer diameter of the magnet 8, but smaller than the outer diameter of the round nail 7. When installing the round nail 7, the top of the round nail 7 is placed into the positioning hole 602 until the bottom of the round nail 7 contacts the annular step 603 and stops descending. The positioning hole 602 radially limits the round nail 7, and the annular step 603 radially limits the magnet 8 in the installation position, so that the central axis of the magnet 8 and the round nail 7 in the installation position are aligned. The magnet 8 is precisely installed and fixed on the round nail 7 by magnetic attraction.

[0043] In this embodiment of the utility model, the sliding support 2, the magnetic feeding column 4, the magnet positioning assembly 5 and the round nail positioning plate 6 are all made of non-magnetic materials, such as engineering plastics or bakelite. While ensuring high mechanical strength, this avoids interference with the displacement and assembly action of the magnet 8, thus affecting the assembly accuracy.

[0044] When the semi-automatic assembly equipment of this utility model is in operation, multiple magnets 8 are installed into the magnetic suction feeding column 4, and the bottom magnet 8 is radially limited by the feeding chamber 42 and falls into the slide groove 202; the round nail 7 is placed in the positioning hole 602 of the round nail positioning plate 6; the manual air source switch 32 is pressed to control the solenoid valve 33 to introduce air into the cylinder 31, drive the piston rod 312 to move, so that the movable push plate 52 drives the bottom magnet 8 to move linearly to the left along the slide groove 202 until it contacts the first arc-shaped part of the fixed positioning plate 51 and stops the displacement, so that the magnet 8 is directly below the round nail 7; under the magnetic attraction, the magnet 8 rises and is radially limited by the annular step part 603, so that the center axis of the magnet 8 and the round nail 7 in the installation position coincides. After passing through the annular step part 603, the magnet 8 is accurately installed and fixed on the round nail 7; the finished magnetic buckle is taken out, the manual air source switch 32 is released, and the piston rod 312 is reset; the assembly operation of the next set of magnetic buckles is carried out.

[0045] This utility model of semi-automatic assembly equipment effectively improves work efficiency, eliminates the constraints of workers' physical strength and skill level, can cope with large-scale production, reduces batch operation time, reduces occupational health risks, replaces long-term repetitive manual operations, reduces the possibility of worker fatigue and strain, and also avoids the problem of decreased assembly quality caused by manual operation fatigue.

[0046] This utility model's semi-automatic assembly equipment can ensure consistent product quality. Through multiple precise positioning methods, including a cylinder-driven movable push plate, a fixed positioning plate, and an annular step, it ensures the concentricity and consistent assembly force of the magnet and the round nail, avoiding problems such as offset and incomplete positioning caused by manual assembly.

[0047] This utility model's semi-automatic assembly equipment can reduce production costs, eliminate the need for complex automation equipment investment, has a compact structure (such as an L-shaped base and modular positioning components), is easy to maintain, and balances low cost and high efficiency, making it suitable for rapid deployment by small and medium-sized enterprises.

[0048] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
