[0002] With the development of the times, industrial production technology is also developing rapidly, and automated equipment is being used more and more in industrial production. At present, O-ring picking equipment can only pick up one O-ring at a time. The picking efficiency of this type of equipment is low. Usually, multiple equipment needs to run at the same time to meet the demand for O-rings, resulting in high production costs. In the industrial field that emphasizes cost reduction and efficiency improvement, it lacks competitiveness and is not conducive to large-scale promotion and industrialized production. Summary of the Invention

[0013] The beneficial technical effects of this invention are as follows: The O-ring batch feeding device includes a base, a gantry mechanism, a pin insertion mechanism, a feeding mechanism, a buffer platform, a discharge platform, and a detection mechanism. In use, multiple O-rings are first placed into the feeding mechanism. Driven by the feeding mechanism, the O-rings move to the outlet of the feeding mechanism. When the detection sensor detects O-rings at all outlets, the pin insertion mechanism moves to the outlet of the feeding mechanism under the drive of the gantry mechanism. The pin moves downward along the Z-axis under the drive of the pin insertion mechanism, and the bottom end of the pin inserts into the O-ring. At this time, the outer peripheral wall of the pin and the inner ring of the O-ring are tightly attached and connected to the O-ring through friction. Then, the pin insertion mechanism and the O-rings move to the detection mechanism under the drive of the gantry mechanism for detection. The mechanism checks if each pin has an O-ring. If any pin is missing an O-ring, the pin insertion mechanism and O-rings move to the buffer platform under the drive of the gantry mechanism. The O-rings then detach from the pins and fall into the second groove, and the process is repeated to prevent missing O-rings during subsequent feeding. When the buffer platform is full of O-rings, they are manually cleaned and returned to the feeding mechanism to avoid waste. If the detection mechanism finds that all pins have O-rings, the pin insertion mechanism and O-rings move to the unloading platform under the drive of the gantry mechanism. The O-rings then detach from the pins and fall into the first groove. Since more than one O-ring is fed at a time, batch feeding is possible, offering the advantage of batch feeding.

[0023] In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] This specific embodiment details the O-ring batch material handling equipment described in this application, such as... Figures 1-5As shown, the O-ring batch feeding device includes: a base plate 1, a gantry mechanism, a pin insertion mechanism, a feeding mechanism, a buffer platform 2, a discharge platform, and a detection mechanism. The gantry mechanism is located next to the base plate 1, and the pin insertion mechanism is fixed to the moving end of the gantry mechanism. The feeding mechanism and the buffer platform 2 are fixed to the top surface of the base plate 1. The buffer platform 2 is adjacent to the feeding mechanism, and the detection mechanism is located between the buffer platform 2 and the discharge platform. The feeding mechanism can accommodate multiple O-rings 3, and multiple discharge ports are arranged side by side on the feeding mechanism. The O-rings 3 in the feeding mechanism can move to the discharge ports of the feeding mechanism under the drive of the feeding mechanism. The discharge ports of the feeding mechanism are equipped with detection sensors that can detect whether there are O-rings 3 at the discharge port. The needle mechanism is equipped with the same number of pins 9 as the discharge port of the feeding mechanism. One pin 9 corresponds to one discharge port. The needle mechanism can move back and forth between the discharge port of the feeding mechanism, the buffer platform 2, the detection mechanism and the unloading platform under the drive of the gantry mechanism. The pins 9 can move back and forth along the Z-axis under the drive of the needle mechanism. The pins 9 can extend into the inner ring of the O-ring 3 located at the discharge port and fit tightly with the inner ring of the O-ring 3. The O-ring 3 fitted on the pins 9 can be disengaged from the pins 9 under the drive of the needle mechanism. The top of the unloading platform is provided with a first groove that can accommodate the O-ring 3. The detection mechanism can detect whether there is an O-ring 3 on the pins 9. The top of the buffer platform 2 is provided with a second groove that can accommodate the O-ring 3. In use, multiple O-rings 3 are first placed into the feeding mechanism. Driven by the feeding mechanism, the O-rings 3 move to the outlet of the feeding mechanism. When the detection sensor detects that all outlets have O-rings 3, the pin insertion mechanism moves to the outlet of the feeding mechanism under the drive of the gantry mechanism. The pin 9 moves downward along the Z-axis under the drive of the pin insertion mechanism, and the bottom end of the pin 9 inserts into the O-ring 3. At this time, the outer peripheral wall of the pin 9 and the inner ring of the O-ring 3 are tightly attached and connected to the O-ring 3 through friction. Then, the pin insertion mechanism and the O-rings 3 move to the detection mechanism under the drive of the gantry mechanism. The detection mechanism checks whether each pin 9 has an O-ring 3. If some pins 9 do not have an O-ring 3... The pin insertion mechanism and O-ring 3 move to the buffer platform 2 under the drive of the gantry mechanism. The O-ring 3 detaches from the pin 9 and falls into the second groove under the drive of the pin insertion mechanism. Then, the feeding process is repeated to avoid missing O-rings 3 during subsequent feeding. When the buffer platform 2 is full of O-rings 3, they are manually cleaned and then placed back into the feeding mechanism to avoid waste. If the detection mechanism detects that all pins 9 have O-rings 3, the pin insertion mechanism and O-ring 3 move to the unloading platform under the drive of the gantry mechanism. Then, the O-ring 3 detaches from the pin 9 and falls into the first groove under the drive of the pin insertion mechanism. Since the number of O-rings 3 fed each time is greater than one, batch feeding is possible. This has the advantage of enabling batch feeding.

[0025] Optionally in this embodiment, the gantry mechanism includes a base 4, a first electric lead screw 5, and a second electric lead screw 6. The first electric lead screw 5 is fixed to the top surface of the base 4, the second electric lead screw 6 is fixed to the moving end of the first electric lead screw 5, and the pin insertion mechanism is fixed to the moving end of the second electric lead screw 6. The second electric lead screw 6 and the pin insertion mechanism can move back and forth along the X-axis under the drive of the first electric lead screw 5, and the pin insertion mechanism can move back and forth along the Z-axis under the drive of the second electric lead screw 6. In this embodiment, the X-axis is parallel to the ground, and the Z-axis is perpendicular to the ground.

[0026] Optionally in this embodiment, the pin insertion mechanism includes a fixed plate 7, a pin holder 8, a first cylinder 10, a first guide rail, a sleeve, a sleeve seat 11, and a second cylinder 12. The side wall of the fixed plate 7 is fixed to the moving end of the second electric lead screw. The guide rail is vertically fixed to any side of the fixed plate 7. The pin holder 8 is slidably connected to the guide rail. A first slot is provided at the bottom end of the pin holder 8. A first locking block that can engage with the first slot is provided at the top end of the pin 9. The first cylinder 10 is fixed to the top end of the base plate 1. The cylinder rod of the first cylinder 10 is connected to the pin holder 8. The second cylinder 12 is fixed to the side wall of the pin holder 8. The top end of the sleeve seat 11 is connected to the second cylinder 12. The cylinder rod of cylinder 2 has a second slot at the bottom of the sleeve seat 11. The outer peripheral wall of the sleeve is provided with a second retaining ring that can engage with the second slot. The number of sleeves is the same as the number of pins 9, with one sleeve corresponding to one pin 9. The two ends of the sleeve are connected, and the inner wall of the sleeve can slide on the pin 9. The pin seat 8, pin 9, sleeve, sleeve seat 11, and second cylinder 12 can move back and forth along the Z-axis under the drive of the first cylinder 10. The sleeve seat 11 and the sleeve can move back and forth along the Z-axis under the drive line of the second cylinder 12. The bottom end of the sleeve can press the O-ring 3 fitted on the pin 9. The bottom end of the pin 9 is provided with a tapered guide. The first cylinder 10 drives the pin 9 to descend along the Z-axis to grab the O-ring 3 located at the outlet of the feeding mechanism. The second cylinder 12 drives the sleeve to descend along the Z-axis to press the O-ring 3 on the pin 9, thereby causing the O-ring 3 to disengage from the pin 9.

[0027] Optionally in this embodiment, a visual positioning camera 13 is provided at the top of the fixed plate 7. The visual positioning camera 13 can provide visual navigation for the gantry mechanism, thereby improving the movement accuracy of the gantry mechanism.

[0028] Optionally, this embodiment also includes a first buffer 14 and a second buffer 16. The first buffer 14 is fixed to the fixing plate 7. A limiting member 15 is provided on the side wall of the pin holder 8 above the first buffer 14, with the buffer end of the first buffer 14 facing the limiting member 15. The limiting member 15 can press the buffer end of the first buffer 14 from top to bottom. The second buffer 16 is fixed to the side wall of the pin holder 8. A clearance opening is provided on the sleeve seat 11 to accommodate the second buffer 16. The buffer end of the second buffer 16 faces upward, and the top wall of the clearance opening can press the buffer end of the second buffer 16 from top to bottom. When the pin holder 8 descends, the first buffer 14 can provide cushioning for the pin holder 8, and when the sleeve seat 11 descends, the second buffer 16 can provide cushioning for the sleeve seat 11.

[0029] Optionally in this embodiment, the number of pins 9 is four, and the four pins 9 are arranged side by side with intervals.

[0030] Optionally in this embodiment, the feeding mechanism includes a vibratory feeder 17, a feeding platform 18, a cover plate, and a photoelectric sensor 24. The vibratory feeder 17 can accommodate multiple O-rings 3. The feeding platform 18 and the vibratory feeder 17 are arranged adjacent to each other. A feeding groove 19 is inclinedly formed on the top surface of the feeding platform 18. Strip-shaped guide grooves for the outer walls of the O-rings 3 to extend into are formed on both sides of the feeding groove 19. The cover plate is placed on the feeding platform 18. The inner wall of the feeding groove 19 and the bottom surface of the cover plate together form a feeding channel. The vibratory feeder 17 is provided with a number of discharge ports equal to the number of feeding channels. One feeding channel corresponds to one discharge port. The first end of the feed channel is higher than the second end of the feeding channel. The first end of the feeding channel is connected to the discharge port, and the second end of the feeding channel is the discharge port of the feeding mechanism. The O-rings 3 in the vibratory feeder 17 can be moved out of the discharge port and into the first end of the feeding channel under the drive of the vibratory feeder 17. The O-rings 3 in the feeding channel can slide to the second end of the feeding channel by gravity. The cover plate has an opening at the second end of the feeding channel for the O-rings 3 to move out. The detection sensor is a photoelectric sensor 24. The feeding platform 18 has a clearance opening at the second end of the feeding channel for the insertion of the pin 9. During feeding, the O-rings 3 in the vibratory feeder 17 are moved out of the discharge port and into the first end of the feeding channel under the drive of the vibratory feeder 17. Since the first end of the feeding channel is higher than the second end of the feeding channel, the O-rings 3 in the feeding channel can slide from the first end of the feeding channel to the second end of the feeding channel by gravity. In this embodiment, the photoelectric sensor 24 includes a transmitter and a receiver. The transmitter can emit laser light to the receiver. When the O-ring 3 moves to the second end of the feeding channel, the O-ring 3 can block the laser light emitted by the transmitter. At this time, the receiver cannot receive the laser light, so it can be determined whether there is an O-ring 3 at the second end of the feeding channel.

[0031] Optionally in this embodiment, two positioning pins 20 are provided at the bottom of the fixing plate 7, and a positioning hole 21 is provided on the feeding table 18 for the positioning pins 20 to extend into. Before the pin 9 picks up the O-ring 3, the positioning pins 20 are first inserted into the positioning hole 21 to fix the pin mechanism and the feeding table 18, and then the pin 9 is driven to pick up the O-ring 3. This can improve the accuracy of the pin mechanism when picking up the O-ring 3 and avoid the pin 9 from shifting during the picking process due to the shaking of the pin mechanism.

[0032] Optionally in this embodiment, the detection mechanism is a visual inspection camera 22, and two strip light sources 23 are arranged at intervals above the visual inspection camera 22.

[0033] The O-ring batch feeding device in this embodiment has the advantage of being able to feed materials in batches.
