[0043] The present invention will be further described below in conjunction with the embodiments and drawings.

[0044] Reference Figure 1 The packaging equipment of the present invention comprises a first feeding device 1, a second feeding device 2, a double-layer rolling device 3, a pneumatic glue dispensing device 4, an electric glue device 5, a crystal expansion device 6 and a bundling device 7; the first feeding device 1 is used to automatically supply a material box carrying a plurality of frames, and the second feeding device 2 is used to automatically supply a plurality of stacked frames. Of course, according to actual needs, the manufacturer can choose to use only the first feeding device 1 or only the second feeding device 2.

[0045] The double-layer rolling device 3 has a first feeding unit and a second feeding unit. The first feeding unit is located above the second feeding unit, and the first feeding unit is used to move the frame moved by the feeding device; the pneumatic dispensing device 4 performs pneumatic dispensing on the frame carried by the first feeding unit; the electric gluing device 5 performs electric gluing on the frame carried by the first feeding unit; similarly, the manufacturer can choose to use only the pneumatic dispensing device 4, or can choose to use only the electric gluing device 5.

[0046] The crystal expansion device 6 is used to automatically expand the crystal element assembly, the bonding head device 7 is used to bond the crystal element after the crystal expansion process of the crystal expansion device 6 to the frame after glue dispensing, and the second feeding unit is used to move the frame bonded with the crystal element, so as to output the frame encapsulated with the crystal element to the required predetermined position.

[0047] It realizes automatic bonding and packaging of crystal components and frames, improving the packaging efficiency of both. It has two dispensing processing methods: pneumatic dispensing and electric dispensing, and two feeding methods: box feeding and part feeding, which improves the compatibility of packaging equipment.

[0048] Reference Figures 1 to 3 The first feeding device 1 includes a first bracket 8, a bracket lifted and lowered on the first bracket 8, a first driving member for driving the first bracket 8 to lift up and down, a push bar 9 that moves horizontally, and a second driving member for driving the push bar 9 to move. In this embodiment, the first driving member includes a motor and a screw-nut assembly. The motor drives the bracket to lift up and down via the screw-nut assembly. The second driving member is a cylinder, which drives the push bar 9 to move back and forth.

[0049] The bracket has multiple trays 11 for carrying material boxes and are arranged in parallel. The trays 11 are arranged parallel to the horizontal plane. The number of push bars 9 is multiple, and the trays 11 and the push bars 9 are staggered. That is, there is a tray 11 between any two adjacent push bars 9, and there is a push bar 9 between any two adjacent trays 11. The push bars 9 are used to move the material boxes carried by the trays 11.

[0050] The first feeding device 1 also includes a left stopper 12, a right stopper 13, a front stopper 14 and a rear stopper 15. The left stopper 12 is fixedly installed on the first bracket 8, the front stopper 14 and the rear stopper 15 slide along the length direction of the left stopper 12 respectively, and the two ends of the right stopper 13 slide along the length direction of the front stopper 14 and the length direction of the rear stopper 15 respectively. The end of the front stopper 14 away from the left stopper 12 slides along the length direction of the right stopper 13, and the end of the front stopper 14 away from the right stopper 13, the end of the rear stopper 15 away from the right stopper 13, and both ends of the right stopper 13 are provided with a baffle 16, which is extended along the moving direction of the bracket, and is used to stop the outer side of the material box or the outer side of the frame from being contacted.

[0051] During the process of lifting the material box or the frame up and down, multiple baffles 16 are used to stop and limit the outside of the material box or the outside of the frame to prevent the material box or the frame from tilting during the lifting process, ensure that the frame accurately enters the material box, and ensure that the material box is accurately pressed on the multiple support plates 11 of the bracket.

[0052] The baffle 16 is provided with a plurality of rolling bearings 17 and a plurality of first springs 18 respectively used to drive the plurality of rolling bearings 17. The plurality of rolling bearings 17 are arranged along the length direction of the baffle 16, and the first springs 18 drive the rolling bearings 17 to contact the outside of the material box or the outside of the frame. The outer ring of the rolling bearing 17 protrudes out of the outer surface of the baffle 16 and contacts the material box or the frame. During the lifting process of the material box or the frame, the movable rolling bearings 17 are used to buffer the deviation of the material box or the frame caused by the processing error, and at the same time, the sliding friction between the baffle 16 and the material box (or the frame) is converted into rolling friction, thereby reducing wear and friction noise.

[0053] Reference Figures 1 to 4 The packaging equipment also includes a material transfer robot 19, which is used to transfer the frame of the first feeding device 1 or the second feeding device 2 to the first transfer unit; the material transfer robot 19 includes a first movable robot arm, a first plate 21 installed on the end of the first robot arm, a strip 22 slidably arranged on the first plate 21, a limiting member used to limit the strip 22 on the first plate 21, and a plurality of suction nozzles 23 arranged on the strip 22, the first plate 21 is provided with a first air hole 24 and a plurality of second air holes 25 respectively connected to the first air hole 24, and the plurality of second air holes 25 are respectively connected to the plurality of suction nozzles 23.

[0054] According to the actual size of the frame, the strip 22 can be slid along the first plate 21, so that the strip 22 and the nozzle 23 move, thereby changing the position of the nozzle 23 relative to the frame, ensuring that the nozzle 23 can accurately suck the frame. By setting the first air hole 24 and the second air hole 25 on the first plate 21, the first air hole 24 is connected to the external air pump, and the second air hole 25 is connected to the nozzle 23 through the air pipe, which simplifies the air path structure and improves the installation efficiency or removal efficiency of the nozzle 23.

[0055] Reference Figures 1 to 6 The double-layer rolling device 3 includes a fixed plate 26, two support plates 27 slidably arranged on the fixed plate 26, a third driving member for driving the two support plates 27 to move closer or farther away, two carrier plates 28 respectively lifted and lowered on the two support plates 27, and a fourth driving member for driving the two carrier plates 28 to move up and down. The fixed plate 26 is horizontally arranged, and the support plates 27 and the carrier plates 28 are both vertically arranged.

[0056] A first ring belt 29 and a second ring belt 31 are rotatably provided on both carriers 28. The carriers 28 are provided with a fifth driving member for driving the first ring belt 29 of the two carriers 28 to rotate and a sixth driving member for driving the second ring belt 31 of the two carriers 28 to rotate. The ring belts are formed with a straight portion for carrying and transferring the frame. The straight portion of the first ring belt 29 of the two carriers 28 forms a first feeding unit, and the straight portion of the second ring belt 31 of the two carriers 28 forms a second feeding unit.

[0057] After the suction nozzle 23 of the material transfer robot 19 sucks the frame, the first robot arm moves the frame sucked by the suction nozzle 23 to the straight part of the first ring belt 29, and then the fifth driving member drives the first ring belt 29 to rotate, and the rotating first ring belt 29 drives the frame carried by the straight part to move.

[0058] In this embodiment, the pneumatic dispensing device 4 and the electric glue device 5 are both equipped with a dispensing table, which has an automatically opening and closing double-layer clamp for clamping the frame. The automatically opening and closing double-layer clamp has roughly the same structure as the double-layer rolling device 3. The packaging equipment is also equipped with a single-layer rolling device. The single-layer rolling device has roughly the same structure as the double-layer roller device 3. The single-layer roller device is only equipped with two first ring belts 29. A lifting mechanism is provided at the lower end of the single-layer roller device. The lifting mechanism drives the single-layer rolling device to move up and down to cooperate with the automatically opening and closing double-layer clamp.

[0059] The frames of the first feeding device 1 and the second feeding device 2 are transported to the upper ring belt of the automatic opening and closing double-layer clamp, the pneumatic gluing device 4 and the electric gluing device 5 perform gluing on the frame of the automatic opening and closing double-layer clamp, the lifting mechanism drives the single-layer rolling device to lift and lower, so that the frame after gluing of the automatic opening and closing double-layer clamp is transported to the single-layer roller device, and then the crystal element after crystal expansion by the crystal expansion device 6 is fixed on the frame of the single-layer roller device, the lifting mechanism drives the single-layer roller device to descend, so that the frame after crystal bonding enters the lower ring belt of the automatic opening and closing double-layer clamp, and the lower ring belt of the automatic opening and closing double-layer clamp inputs the frame after crystal bonding into the material box.

[0060] The upper and lower ring belts of the automatic opening and closing double-layer fixture do not affect each other during rolling transmission, greatly improving the working efficiency. At the same time, the frame automatically returns to its original position after feeding, dispensing, solidifying, and collecting, realizing the unilateral entry and exit of the frame. Compared with the existing technology where the frame is operated from left to right, the collecting mechanism is eliminated, the length of the production line is shortened, and the equipment use cost is reduced.

[0061] The fixed plate 26 is provided with a support arm 32, and the support arm 32 is provided with a positioning column 33 and a magnet 34. The magnet 34 is used to attract the magnetic plate 35. The magnetic plate 35 has a positioning hole for accommodating the positioning column 33. The magnetic plate 35 is located between the two carriers 28; the carrier 28 is provided with a pressure strip 36, and the pressure strip 36 is used to press the frame on the magnetic plate 35. After the first ring belt 29 moves the frame carried by the straight part to the magnetic plate 35, the fourth driving member drives the two carriers 28 to descend until the pressure strip 36 presses the frame on the magnetic plate 35, and then the pneumatic glue device 4 or the electric glue device 5 can glue the frame clamped by the pressure strip 36 and the magnetic plate 35. Preferably, there are multiple pressure strips 36, and the multiple pressure strips 36 are arranged along the length direction of the carrier 28, and the multiple pressure strips 36 press different positions of the frame carried by the magnetic plate 35.

[0062] Reference Figures 1 to 8 The crystal expansion device 6 includes a second bracket 37, a loading platform 38 rotatably arranged on the second bracket 37, a seventh driving member for driving the loading platform 38 to rotate, a crystal expansion member 39 lifted and lowered on the second bracket 37, an eighth driving member for driving the crystal expansion member 39 to rise and fall, a crystal expansion pressure plate 41 rotatably arranged on the crystal expansion member 39 and used in conjunction with the loading platform 38, and a clamping unit 42 for clamping the loading platform 38. The loading platform 38 is used to carry the wafer assembly, and the crystal expansion pressure plate 41 is used to perform crystal expansion processing on the wafer assembly carried by the loading platform 38.

[0063] When it is necessary to expand the wafer assembly carried by the carrier 38, the clamping unit 42 clamps the carrier 38 to prevent the carrier 38 from rotating relative to the second bracket 37, and then the eighth driving member drives the expanding member 39 to move toward the carrier 38, and the expanding plate 41 of the expanding member 39 is used to expand the wafer assembly carried by the carrier 38. When it is necessary to rotate the wafer assembly, the clamping unit 42 releases the rotating table, and the seventh driving member drives the carrier 38 to rotate to change the angle of the wafer assembly.

[0064] The loading platform 38 is provided with an annular protruding rib 43 and a first annular groove 44, both of which are arranged around the central axis of the loading platform 38. The first driving member includes a third annular belt sleeved on the outside of the loading platform 38 and located in the first annular groove 44, and a motor for driving the third annular belt to rotate. In actual use, the motor drives the third annular belt to rotate, and the rotating third annular belt drives the loading platform 38 to rotate relative to the second bracket 37.

[0065] The second bracket 37 is rotatably provided with a plurality of wheels 45, which are arranged around the loading platform 38. The wheels 45 are provided with a second annular groove 46 around the rotation axis of the wheels 45, and the annular protruding rib 43 extends into the second annular groove 46 of the plurality of wheels 45. The arrangement of the wheels 45 allows the loading platform 38 and the second bracket 37 to be rotatably arranged on the one hand, and reduces the wear required for the relative rotation between the loading platform 38 and the second bracket 37 on the other hand.

[0066] Reference Figures 1 to 10 The bun head device 7 includes a third bracket 47, a carrier 48 rotatably arranged with the third bracket 47, a ninth driving member for driving the carrier 48 to rotate, a slide 49 lifted and lowered on the carrier 48, a slide plate 51 rotatably arranged with the slide 49 and lifted and lowered on the third bracket 47, a tenth driving member for driving the slide plate 51 to be lifted and lowered, a spring piece 52 arranged on the slide 49, and a cantilever 53 matched with the spring piece 52, the spring piece 52 is roughly flat, the middle part of the cantilever 53 is installed on the spring piece 52, one end of the cantilever 53 is provided with a picking piece 54 for picking up the crystal element after the crystal expansion process of the crystal expansion device 6, the slide 49 is provided with a dynamometer, and the other end of the cantilever 53 acts on the dynamometer.

[0067] During actual use, the ninth driving member drives the carrier 48 to rotate, and the rotating carrier 48 drives the picking member 54 to rotate via the cantilever 53, thereby changing the angle between the picking member 54 and the crystal element after expansion by the crystal expansion device 6, and then the tenth driving member drives the slide plate 51 to slide up and down, and the sliding slide plate 51 drives the slide seat 49 to move up and down, and the up and down moving slide seat 49 drives the picking member 54 to move up and down via the cantilever 53, so that the picking member 54 picks up the crystal element after expansion.

[0068] When the picking member 54 picks up the crystal component, the crystal component acts on the dynamometer via the picking member 54 and the cantilever 53. The dynamometer displays the magnitude of the force applied to the crystal component by the picking member 54. According to the magnitude of the force displayed by the dynamometer, the lifting and lowering stroke of the sliding plate 51 and the sliding seat 49 are regulated by the tenth driving member to prevent the picking member 54 from excessively descending and damaging the crystal component, thereby ensuring the accurate moving stroke of the picking member 54 and avoiding poor installation between the crystal component and the frame due to inaccurate stroke of the picking member 54.
