Description

[0003] Chinese patent CN219665634U discloses a pin installation device and pin assembly equipment, including a frame, a supporting mechanism, and a pin pressing mechanism. The frame forms a working space, the supporting mechanism is mounted on the frame and is used to support the part to be pinned, and the pin pressing mechanism is mounted on the frame. The supporting mechanism and the pin pressing mechanism are arranged vertically opposite each other in the working space. The supporting mechanism has a protruding limiting post, which is used to fit into the mounting hole of the part to be pinned. The pin pressing mechanism is used to press the first end of the pin into the mounting hole of the part to be pinned, and the first end face of the limiting post abuts against the first end face of the pin. Because the limiting post limits the depth of the pin inserted into the mounting hole, this device still has the following problems in use:

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0045] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0046] In some embodiments, please refer to the accompanying drawings. Figures 1-7 A fully automatic pin assembly device includes a base plate 1, an adjustable pin assembly mechanism 2, a flipping feeding mechanism 3, a contour jig 4, and a material transfer cylinder 5; the upper front end of the base plate 1 is slidably fitted with a contour jig 4 for placing spring clips that have not been assembled with pins.

[0047] A material transfer cylinder 5 is fixedly installed at the front end of the base plate 1; the output end of the material transfer cylinder 5 is fixedly connected to the contour jig 4.

[0048] An adjustable pin assembly mechanism 2 for automatically assembling the spring clip is installed at the upper middle part of the base plate 1.

[0049] like Figure 1 As shown, the adjustable pin assembly mechanism 2 includes a mounting frame 21, a pressing assembly 22 for controlling the movement of the pins, a pin feeding assembly 23 for adaptive receiving of pins of different lengths, and a pin conveying pipe 24; the pressing assembly 22 is mounted on the mounting frame 21; the pin feeding assembly 23 is connected to the pressing assembly 22; the pin conveying pipe 24 is connected to the pin feeding assembly 23; the outside of the pin conveying pipe 24 is connected to the outlet of the pin vibratory feeder; and a blocking cylinder for blocking the pin feeding is installed at the outlet of the pin vibratory feeder.

[0050] A vibratory feeder for conveying torsion springs is fixedly installed on the upper rear side of the base plate 1;

[0051] A flipping feeding mechanism 3 is installed on the upper rear side of the base plate 1 to control the movement and flipping of the torsion spring and realize automatic assembly.

[0052] The spring clip has a pin groove in the middle for insertion of a pin.

[0053] The torsion spring is made of magnetic material;

[0054] In this utility model, the spring clip that needs to be assembled with pins is placed in the contour jig 4; then the material transfer cylinder 5 pushes the contour jig 4 to move below the pressing assembly 22;

[0055] Subsequently, the flipping feeding mechanism 3 fixes the torsion spring at the outlet of the torsion spring vibratory feeder; at this time, the flipping feeding mechanism 3 also blocks the next torsion spring from moving forward at the outlet of the torsion spring vibratory feeder; then the flipping feeding mechanism 3 drives the torsion spring to flip forward and moves the torsion spring into the spring clamp. During the movement, it also controls the torsion arms on both sides of the torsion spring to bend automatically until the middle of the torsion spring is aligned with the pin groove opened in the middle of the spring clamp.

[0056] When the pin vibratory feeder is working, it moves a pin into the pin conveying pipe 24; and when the blocking cylinder is working, it will prevent the next pin from moving out of the outlet of the pin vibratory feeder.

[0057] The pins that fall into the pin delivery tube 24 will enter the pin feeding assembly 23;

[0058] Then the pressing assembly 22 works to push the pin on the pin feeding assembly 23 into the pin groove opened in the middle of the spring clip, thereby fixing the torsion spring and the spring clip; then the spring clip with the pin assembled can be removed.

[0059] like Figure 2 As shown, the pressing assembly 22 includes a push cylinder 221, a guide rod 222, a moving plate 223, a fixed plate 224, and a pressing rod 225; the push cylinder 221 is fixedly installed in the middle of the upper end of the mounting frame 21; the fixed plate 224 is fixedly installed in the middle of the mounting frame 21.

[0060] Multiple guide rods 222 are arranged in a rectangular array on the upper end of the mounting frame 21. The upper ends of the guide rods 222 are fixedly connected to the mounting frame 21. The lower ends of the guide rods 222 are fixedly connected to the fixed plate 224. The movable plate 223 is slidably connected to the guide rods 222. The output end of the push cylinder 221 is fixedly connected to the movable plate 223. A pressure rod 225 is fixedly installed in the middle of the lower end of the movable plate 223. The lower end of the pressure rod 225 is slidably connected to the middle of the fixed plate 224.

[0061] like Figure 4 and Figure 6As shown, the pin feeding assembly 23 includes a first rotary cylinder 231, a support connecting plate 232, a limiting plate 233, a fixed arc plate 234, and a swing cylinder 235; the fixed arc plate 234 is fixedly connected to the fixed plate 224 through a connecting frame; the support connecting plate 232 is symmetrically fixedly installed at the front and rear ends of the fixed arc plate 234; the first rotary cylinder 231 is fixedly installed at the rear end of the rear support connecting plate 232; the front and rear ends of the swing cylinder 235 are hinged to the ends of the front and rear support connecting plates 232 that are close to each other; limiting plates 233 for restricting the movement of the swing cylinder 235 are fixedly installed on both the left and right sides of the fixed arc plate 234; the output end of the first rotary cylinder 231 is fixedly connected to the swing cylinder 235.

[0062] A pressing groove 238 is provided at the middle of the upper end of the fixed arc plate 234;

[0063] A positioning groove 236 is provided in the middle of the swing cylinder 235;

[0064] Limiting baffles 2351 are hinged to the left and right sides of the lower end of the swing cylinder 235;

[0065] A reset torsion spring is wound around the rotating shaft of the limiting baffle 2351 and the swing cylinder 235. One end of the reset torsion spring is fixedly connected to the limiting baffle 2351, and the other end of the reset torsion spring is fixedly connected to the swing cylinder 235.

[0066] The upper end of the swing cylinder 235 is arc-shaped, and the upper end of the swing cylinder 235 is slidably connected to the lower arc surface of the fixed arc plate 234.

[0067] A pin groove 237 is provided on the upper left side of the fixed arc plate 234; a pin conveying pipe 24 is fixedly installed on the pin groove 237.

[0068] The pressure rod 225 is made of an elastic material, allowing it to provide clamping force to pins of different lengths. When the pressure rod 225 contacts a shorter pin, it drives the pin along the clamping groove 238 into the pin slot of the spring clip. After the pin is inserted and fixed in the slot, it presses the lower end of the pressure rod 225, causing it to deform and contract, thus keeping the lower end of the pressure rod 225 in contact with the pin. This ensures that the pressure rod 225 always provides clamping force to the pin.

[0069] like Figure 4 and Figure 5As shown, the flipping feeding mechanism 3 includes a second rotary cylinder 31, an L-shaped flipping plate 32, a de-energized electromagnet 33, a dual-axis cylinder 34, a push plate 35, a limiting pressure plate 36, and a blocking cylinder 37; the second rotary cylinder 31 is fixedly installed on the upper rear left side of the base plate 1; the output end of the second rotary cylinder 31 is fixedly connected to the long side end of the L-shaped flipping plate 32; the de-energized electromagnet 33 is fixedly installed on the short side end of the L-shaped flipping plate 32;

[0070] The de-energized electromagnet 33 consists of a coil, an iron core, and a permanent magnet. When the coil is not energized, the magnetic field of the permanent magnet makes the electromagnet magnetic and can attract magnetically conductive materials; if the coil is energized, the generated magnetic field will interact with the magnetic field of the permanent magnet, causing the magnetism to weaken or disappear, thereby achieving demagnetization.

[0071] The coil of the de-energized electromagnet 33 is electrically connected to an external power source via a wire;

[0072] The dual-axis cylinder 34 is fixedly installed on the upper rear side of the base plate 1; the output end of the dual-axis cylinder 34 is fixedly connected to the push plate 35; the front end of the push plate 35 is provided with an arc-shaped groove 351;

[0073] The opening diameter of the arc-shaped groove 351 is the same as the diameter of the middle part of the torsion spring;

[0074] A limiting pressure plate 36 is fixedly installed on the upper rear side of the base plate 1; and the left and right inner walls of the limiting pressure plate 36 are provided with inclined surfaces for controlling the bending of the torsion arms on both sides of the torsion spring; the rear side of the inclined surface is provided as a wide part; the front side of the inclined surface is provided as a narrow part.

[0075] A material-blocking cylinder 37 is also fixedly installed on the upper end of the base plate 1; a material-blocking rod for limiting the discharge of the torsion spring is fixedly installed on the output end of the material-blocking cylinder 37.

[0076] In this utility model, the spring clip that needs to be assembled with pins is placed in the contour jig 4; the material transfer cylinder 5 works to push the contour jig 4 below the swing cylinder 235;

[0077] At this time, the de-energized electromagnet 33 works to attract and fix the torsion spring at the discharge port of the torsion spring vibratory feeder; and the baffle cylinder 37 works to drive the baffle rod to move, blocking the next torsion spring at the discharge port of the torsion spring vibratory feeder from moving forward.

[0078] Then the second rotary cylinder 31 works to drive the L-shaped flip plate 32 to flip 90 degrees, and the de-energized electromagnet 33 drives the torsion spring to move together until the torsion spring is in a horizontal state; then the dual-axis cylinder 34 works to push the push plate 35 forward. During the movement, the arc groove 351 will come into contact with the torsion spring. Then the de-energized electromagnet 33 is energized, so that the de-energized electromagnet 33 releases the attraction effect on the torsion spring.

[0079] like Figure 7 As shown, the push plate 35 then drives the torsion spring to move forward. During the movement, the torsion arms on both sides of the torsion spring contact the wide part of the inclined surface of the left and right inner walls of the limiting pressure plate 36. When the torsion spring moves from the wide part to the narrow part of the limiting pressure plate 36, the torsion arms on both sides of the torsion spring will bend under the action of the inclined surface. When the push plate 35 pushes the torsion spring to separate from the limiting pressure plate 36, the torsion arms on both sides of the torsion spring will contact the inner walls of the front and rear of the spring clip, and keep the torsion arms on both sides of the torsion spring bent until the middle part of the torsion spring is aligned with the pin groove opened in the middle part of the spring clip.

[0080] Subsequently, the dual-axis cylinder 34 operates, driving the push plate 35 to reset backward;

[0081] Then the first rotary cylinder 231 works to drive the swing cylinder 235 to rotate to the left until the left end of the swing cylinder 235 touches the limiting plate 233 on the left side of the fixed arc plate 234. At this time, the positioning groove 236 opened on the swing cylinder 235 is aligned with the pin through groove 237.

[0082] Subsequently, the pin vibratory feeder device operates, driving a pin to move into the pin conveying pipe 24; and the blocking cylinder installed at the outlet of the pin vibratory feeder device operates, preventing the next pin from moving out of the outlet of the pin vibratory feeder device.

[0083] The pins in the pin conveying pipe 24 enter the positioning groove 236 through the pin through groove 237 and are blocked by the limiting baffle 2351 set below the swing cylinder 235; then the first rotary cylinder 231 works to drive the swing cylinder 235 to rotate to the right and reset. At this time, the right end of the swing cylinder 235 is limited by the limiting plate 233 on the right side of the fixed arc plate 234; and at this time, the positioning groove 236 opened on the swing cylinder 235 is aligned with the pressing groove 238.

[0084] Then, the pusher cylinder 221 works to push the moving plate 223 downward along the guide rod 222. At this time, the pressure rod 225 follows the moving plate 223 and moves downward along the fixed plate 224. During the movement, the lower end of the pressure rod 225 will pass through the positioning groove 236 opened on the fixed arc plate 234 and enter the positioning groove 236 until the lower end of the pressure rod 225 contacts the upper end of the pin. Then, the pressure rod 225 drives the pin to continue to move downward. During the movement, the pin will push the limit baffles 2351 on the left and right sides of the lower end of the swing cylinder 235 to flip in opposite directions at the same time until the pin is inserted into the pin groove opened in the middle of the spring clip. At this time, the pin is located in the middle of the torsion spring. Then, the spring clip with the pin assembled can be removed.

[0085] The cooperation of the first rotary cylinder 231 and the swing cylinder 235 aligns the positioning groove 236 with the pin through groove 237 and the pressing groove 238 respectively. This allows pins of different sizes to first fall into the positioning groove 236 through the pin through groove 237, and then move to the pressing groove 238 for assembly. This avoids the problem of long pins directly entering the positioning groove 236 and getting stuck, which would cause material to be stuck and unable to be discharged. It also reduces the extra workload of manually inserting pins into the pin groove. The cooperation of the second rotary cylinder 31 and the de-energized electromagnet 33 enables the device to automatically position and assemble the torsion spring, further improving the efficiency of pin assembly.

[0086] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
