Description

[0002] After the PCB board is tested, it will enter the packaging stage, which is crucial to ensure the safe delivery of the product to the customer. Before the PCB board is loaded into the shipping box, it will be carefully wrapped in anti-static packaging or bubble packaging to prevent damage caused by static electricity or physical collision during transportation.

[0003] At present, when using protective packaging such as anti-static packaging and bubble packaging, a wrapping method is often used.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Example: Combination Figure 1-Figure 4As shown, it includes: a mounting seat 101, the rear lower part of the mounting seat 101 is open, and the inner bottom of the mounting seat 101 is provided with an inclined surface, which leads to the opening; a support frame 103 fixedly mounted on the front side of the mounting seat 101; a loading shaft 104 rotatably mounted on the support frame 103, and the protective package 001 is rolled on the loading shaft 104, and the loading shaft 104 can be removed from the support frame 103; a material guide device 105 arranged on the mounting seat 101, and the material guide device 105 is used to limit the position of the protective package 001 and provide tension for the protective package 001 The material guiding device 105 is composed of a mounting bar 1501, a first roller 1502 and a first spring 1503. The mounting bar 1501 is provided with two upper and lower ones, one of which is slidably installed on the mounting seat 101, and the other is fixedly installed on the mounting seat 101. There are two first rollers 1502, which are rotatably installed on the two mounting bars 1501 respectively. The first spring 1503 is provided on the mounting bar 1501 which is slidably connected to the mounting seat 101, and the two ends of the first spring 1503 are respectively fixed to the mounting seat 101 and the mounting bar 1501.

[0029] The loading shaft 104 is removed from the support frame 103, the rolled protective package 001 is passed through the loading shaft 104, and then the loading shaft 104 is placed on the support frame 103, the end of the protective package 001 is pulled out, and the protective package 001 is passed through the material guiding device 105. The first spring 1503 makes the two first rollers 1502 close to the protective package 001 and limits the position of the protective package 001. In this way, even if the height position of the protective package 001 changes with the use of the protective package 001, it will eventually be used at the height of the position of the material guiding device 105, so that the height position change of the protective package 001 will not affect the subsequent automatic packaging operation. In addition, the material guiding device 105 can also apply tension to the protective package 001 to avoid the protective package 001 from being loose, which is conducive to the protective package 001 wrapping the PCB board 002.

[0030] Combination Figure 1-Figure 4As shown, it also includes: a support 102 fixedly mounted on the right side of the mounting base 101; a rotating mechanism arranged on the support 102 for wrapping the protective package 001 around the PCB board 002 to realize automatic packaging operation, the rotating mechanism including: a rotating base 201 rotatably mounted between the support 102 and the mounting base 101; a first motor 202 fixedly mounted on the right side of the support 102, the output end of the first motor 202 is fixed to the rotating base 201 to drive it to rotate; a holding fork plate 203 slidably mounted on the left side of the rotating base 201, the holding fork plate 203 is hollow in the middle and has no edge on the left side, the holding fork plate 203 is located at the inner rear part of the mounting base 101, and the holding fork plate 203 rotates to control the protective package 001 to wrap around the PCB board 002; a first electric cylinder 204 fixedly mounted on the rotating base 201, the connecting end of the first electric cylinder 204 is fixed to the holding fork plate 203 to drive it to move left and right.

[0031] After the protective package 001 passes through the restriction of the material guide device 105, it will be delivered to the receiving fork plate 203. Then, the protective package 001 is controlled to be aligned with the receiving fork plate 203, and the end of the protective package 001 passes through the receiving fork plate 203, so that the protective package 001 is inserted on the receiving fork plate 203. After that, the first motor 202 is started to control the rotating seat 201 and the receiving fork plate 203 to rotate 360 ​​degrees to wrap the protective package 001 on the receiving fork plate 203. After that, every time a PCB board 002 is placed on the receiving fork plate 203, the protective package 001 is controlled to be aligned with the receiving fork plate 203, and the end of the protective package 001 passes through the receiving fork plate 203, so that the protective package 001 is inserted on the receiving fork plate 203. The holding fork plate 203 is controlled to rotate 180 degrees once, so that the protective packaging 001 can be automatically used to wrap the PCB board 002 to realize automatic packaging; when the packaging operation is completed, the first electric cylinder 204 controls the holding fork plate 203 to move rightward and retract into the rotating seat 201, and the right side wall of the mounting seat 101 will push the packaged PCB board 002 packaging material to separate the PCB board 002 packaging material from the holding fork plate 203, and finally, the PCB board 002 packaging material is discharged from the open opening along the inclined surface at the bottom of the mounting seat 101 for unified collection.

[0032] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it also includes: a material-retaining mechanism for limiting the position of the PCB board 002 arranged on the mounting seat 101, the material-retaining mechanism including: a rotating frame 301 rotatably mounted on the front part of the mounting seat 101; a second electric cylinder 302 fixedly mounted on the rotating frame 301; a connecting frame 303 fixedly mounted on the connecting end of the second electric cylinder 302; a resisting frame 304 slidably mounted on the connecting frame 303, the resisting frame 304 is used to resist the PCB board 002 against the holding fork plate 203 to prevent it from falling during the rotation of the holding fork plate 203; a second roller 305 rotatably mounted on the resisting frame 304, the second roller 305 makes the resisting frame 304 roll in contact with the PCB board 002; a second spring 306 fixedly mounted between the resisting frame 304 and the connecting frame 303.

[0033] After the PCB board 002 is placed on the receiving fork plate 203, the second electric cylinder 302 is started, controlling the connecting frame 303 to extend, and the supporting frame 304 is pressed against the PCB board 002. Then, during the subsequent rotation of the receiving fork plate 203 by 180 degrees, the supporting frame 304 will keep the PCB board 002 always close to a section of protective packaging 001 located below it, until this PCB board 002 rotates to a position below the receiving fork plate 203, at which time the PCB board 002 will be supported by a new section of protective packaging 001 delivered to the receiving fork plate 203, and the second electric cylinder 302 controls the connecting frame 303 to be retracted, and then a new PCB board 002 is added above the receiving fork plate 203, and the above steps are repeated. Such a cycle can realize the automatic packaging operation of the PCB board 002 by the packaging equipment.

[0034] Therefore, the support frame 304 is used to assist in protecting the package 001 to wrap around the PCB board 002. By restricting the PCB board 002, the PCB board 002 can be accurately and stably positioned for packaging operations, thereby ensuring the quality of the PCB board 002 packaged by this packaging equipment; the second spring 306 allows the support frame 304 to have soft contact, and the second roller 305 allows the support frame 304 to have smooth contact with the PCB board 002. The second is used to optimize the use of the support frame 304, so that the support frame 304 can better assist in the packaging operation to prevent damage to the PCB board 002.

[0035] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the material-blocking mechanism also includes: first gears 311 fixedly mounted on the left and right ends of the rotating frame 301; a moving plate 312 slidably mounted on the right side of the mounting seat 101, the moving plate 312 moves forward and backward, and the moving plate 312 is located above the rotating seat 201; a first tooth portion 313 fixedly mounted on the front end of the moving plate 312, the first tooth portion 313 meshing with the first gear 311 on the right side; a second tooth portion 314 fixedly mounted on the rear end of the moving plate 312; a track 31 is provided on the right side of the mounting seat 101 5, the track 315 is arranged on the outer ring of the rotating seat 201; two protruding teeth 316 are fixedly installed on the left side of the rotating seat 201, and the protruding teeth 316 are meshed with the second tooth portion 314. The two protruding teeth 316 are symmetrically arranged on the rotating seat 201, so that the rotating seat 201 can control the moving plate 312 to move forward by one stage every time it rotates 180 degrees. During the rotation of the rotating seat 201, the protruding teeth 316 move in the track 315. When the fork plate 203 is in a horizontal position, the position of the protruding teeth 316 is as shown in FIG. Figure 6 As shown, no engagement with the moving plate 312 will occur.

[0036] When the fork plate 203 rotates 180 degrees every time, when it is close to completing the rotation action, the rotating seat 201 controls the movable plate 312 to move forward one stage through the cooperation of the convex tooth 316 and the second tooth portion 314, and the first tooth portion 313 controls the rotating frame 301 to rotate one stage through the cooperation with the first gear 311 on the right side, and controls the first electric cylinder 204 to lift up; as the packaging operation of the PCB board 002 progresses, the PCB board 002 packaging wrapped on the fork plate 203 gradually thickens. At the same time, the first electric cylinder 204 and the upper support frame 304 are also controlled to be continuously lifted upward, that is, the support frame 304 can change accordingly to adapt to the continuously thickening PCB board 002 packaging, thereby optimizing the use of the support frame 304.

[0037] Combination Figure 1 , Figure 2 and Figure 7As shown, it also includes: a feeding mechanism for automatically feeding the PCB board 002 arranged on the mounting seat 101, the feeding mechanism including: a mounting shaft 401 rotatably mounted on the upper part of the mounting seat 101, the mounting shaft 401 being located directly above the fork plate 203; a transfer belt 402 wound between the mounting shafts 401, the transfer belt 402 being vertically arranged, and the transfer belt 402 being provided with two front and rear layers; a support block 403 fixedly mounted on the transfer belt 402, the height positions of the support blocks 403 on the two layers of transfer belts 402 corresponding to each other, so as to cooperate together and support the PCB board 002 in a hierarchical manner; a second motor 404 fixedly mounted on the left side of the mounting seat 101, the output end of the second motor 404 being fixed to one of the mounting shafts 401; a second gear 405 arranged at the left end of the two mounting shafts 401 at the bottom, the second gears 405 being meshed, and the second gear 405 cooperating with the transfer belt 402 to make all the mounting shafts 401 rotate synchronously, and to make the rotation directions of the front and rear layers of the transfer belts 402 opposite.

[0038] The PCB board 002 is placed on the transfer belt 402, and the second motor 404 is started to control the transfer belt 402 to move the PCB board 002 downward. When the support block 403 moves to the bottom of the transfer belt 402, the transfer belt 402 will separate the support blocks 403 on the same layer from each other. Therefore, the PCB board 002 can be added from the transfer belt 402 to the holding fork plate 203, thereby realizing the accurate loading of the PCB board 002 and replacing manual loading, thereby improving the accuracy of the loading operation of the packaging equipment and avoiding the influence of the manual placement of the PCB board 002 on the operation of the rotating mechanism and the material resistance mechanism.

[0039] Combination Figure 2 , Figure 8 and Fig. 9 As shown, it also includes: a gluing mechanism arranged on the mounting base 101 for gluing the PCB board 002 packaging to prevent the PCB board 002 packaging from spreading, and the gluing mechanism includes: a bracket 501 fixedly mounted on the lower part of the mounting base 101; a guide rod 502 fixedly mounted on the bracket 501; a first threaded rod 503 rotatably mounted on the bracket 501; a third motor 504 fixedly mounted on the left side of the bracket 501, and the output end of the third motor 504 is fixed to the first threaded rod 503 to drive the first threaded rod 503 to rotate; a gluing machine 505 slidably mounted on the guide rod 502, the gluing machine 505 is threadedly mounted on the first threaded rod 503, and the gluing machine 505 will move left and right below the fork plate 203.

[0040] When the PCB board 002 packaging material reaches the specified thickness, the protective packaging 001 is cut, and the third motor 504 is started. By controlling the first threaded rod 503 to rotate, the glue sticking machine 505 is controlled to move from left to right, and the tape is attached to the end of the protective packaging 001 on the PCB board 002 packaging material to prevent the protective packaging 001 from spreading. After fixing, the third motor 504 controls the first threaded rod 503 to rotate in the opposite direction, and moves the glue sticking machine 505 back to the left side of the mounting seat 101.

[0042] The third electric cylinder 602 is started to control the clamping plate 603 to clamp and fix the protective package 001, and then the protective package 001 is cut. At this time, the new end of the protective package 001 is clamped and fixed by the clamping plate 603; after the previous batch of PCB board 002 packages are discharged, the fourth motor 605 is started to control the second threaded rod 604 to rotate, and the installation frame 601 is controlled to move backward, and the protective package 001 is moved to the holding fork plate 203 and aligned with the holding fork plate 203, thereby realizing automatic loading of the protective package 001; after completion, the third electric cylinder 602 controls the two clamping plates 603 to separate, and the fourth motor 605 controls the installation frame 601 to move forward. At this time, the two clamping plates 603 return forward from the upper and lower sides of the protective package 001 respectively to prevent affecting the position of the protective package 001 at this time.

[0043] Combination Figure 1 , Fig.10 and Fig.11As shown, a cutting mechanism for cutting protective packaging 001 is arranged on a mounting seat 101, and the cutting mechanism includes: a cutter 701 slidably mounted on the mounting seat 101, two cutters 701 are provided, and the cutters 701 are arranged on the rear side of the clamping plate 603; a fourth electric cylinder 702 fixedly mounted on the right side of the mounting seat 101, and the connecting end of the fourth electric cylinder 702 is fixed to the cutter 701 at the lower position; racks 703 fixedly mounted on the right sides of the two cutters 701 respectively; a third gear 704 rotatably mounted on the right side wall of the mounting seat 101, and the third gear 704 is meshed with both racks 703 to control the two racks 703 to move synchronously and in opposite directions.

[0044] The fourth electric cylinder 702 is started, and with the cooperation of the third gear 704 and the rack 703, the two cutters 701 are controlled to approach each other, thereby realizing automatic cutting of the protective packaging 001. After completion, the fourth electric cylinder 702 controls the two cutters 701 to separate.

[0045] Combination Fig.12 As shown, it also includes: a locking mechanism arranged on the mounting seat 101 for cooperating with the material-resisting mechanism, the locking mechanism including: a support plate 801 fixedly mounted on the left side wall of the mounting seat 101, the support plate 801 being located behind the first gear 311 on the left side; a control arm 802 rotatably connected to the support plate 801; a clamping block 803 rotatably connected to the control arm 802, the clamping block 803 abuts against the teeth of the first gear 311 on the left side; a push rod 804 slidably connected to the side wall of the mounting seat 101, the upper end of the push rod 804 being able to contact the control arm 802, the lower end of the push rod 804 being provided with an inclined surface, and the movement of the mounting frame 601 will contact the inclined surface of the lower end of the push rod 804; a first torsion spring 805 fixedly connected between the clamping block 803 and the control arm 802; a second torsion spring 806 fixedly connected between the support plate 801 and the control arm 802.

[0046] Combination Figure 6 As shown, the material resistance mechanism also includes: a connecting rod 317 fixedly mounted on the right side of the mounting seat 101, the connecting rod 317 and the movable plate 312 are slidably mounted; a third spring 318 sleeved on the connecting rod 317, and the two ends of the third spring 318 are respectively fixed to the connecting rod 317 and the movable plate 312.

[0047] In the normal state, the mounting frame 601 is located at the lower end of the push rod 804, and the mounting frame 601 limits the push rod 804 to fix its position, and limits the control arm 802 through the push rod 804, so that the control arm 802 cannot rotate. At this time, the block 803 is against the teeth of the first gear 311 on the left side. Therefore, at this time, the first gear 311 on the left side can only rotate forward, and the first torsion spring 805 is deformed by squeezing the block 803, but cannot be reversed, because the first gear 311 on the left side is limited by the block 803 in this direction, and the first torsion spring 805 is not rotated. The spring 805 cannot be deformed, that is, after the rotating frame 301 rotates upward, it cannot rotate back downward, that is, in the process of controlling the protective packaging 001 to wrap around the PCB board 002 and perform the packaging operation, the support frame 304 can only be controlled to rotate upward step by step; when the packaging operation is completed and the PCB board 002 packaging is unloaded, the installation frame 601 moves backward to add the next section of protective packaging 001 to the fork plate 203 to perform the packaging operation of the next batch of PCB boards 002. The rod 804 is separated, and the top rod 804 moves downward under the action of gravity, unlocking the restriction on the control arm 802. The control arm 802 rotates downward under the action of the second torsion spring 806, thereby driving the block 803 to rotate away from the first gear 311. Previously, the moving plate 312 was continuously moved forward in stages, and the third spring 318 was compressed. Therefore, at this time, the third spring 318 can return the moving plate 312 to its original position, and the first tooth portion 313 reversely rotates the first gear 311 on the right side, so that the rotating frame 301 and the support frame 304 return to their original positions. , so as to cooperate with the next batch of PCB boards 002 and protective packaging 001. During the process; after the clamping plate 603 moves the protective packaging 001, the installation frame 601 moves forward and returns to its position, and the installation frame 601 moves the push rod 804 on the inclined surface of the lower end of the push rod 804, so that the control arm 802 rotates upward, the second torsion spring 806 is deformed, and the control arm 802 drives the block 803 to rotate and contact the first gear 311, so that the block 803 again restricts the one-way rotation of the first gear 311 on the left side.

[0048] In summary, the complete sequence of this packaging equipment is: First, the protective package 001 is loaded onto the support frame 103, the end of the protective package 001 is pulled out and passed through the material guide device 105, and is placed on the receiving fork plate 203, the second electric cylinder 302 is started, and the support frame 304 is controlled to pass the protective package 001 through the receiving fork plate 203, the first motor 202 is started, and the receiving fork plate 203 is controlled to rotate, and the protective package 001 is wrapped around the receiving fork plate 203; secondly, the PCB board 002 is placed on the unloading mechanism, and the second motor 404 is started to control the transfer belt 402 to move the PCB board 002 002 is accurately added to the fork plate 203. From then on, each time a PCB board 002 is placed, the support frame 304 is controlled to abut against the newly added PCB board 002, and then the fork plate 203 is controlled to rotate 180 degrees to wrap the protective package 001 around each PCB board 002. At the same time, the rotating frame 301 and the support frame 304 are gradually controlled to rotate upward; when the PCB board 002 packaging reaches the specified thickness value, the PCB board 002 is stopped from being added, and the third electric cylinder 602 is started to control the clamping plate 603 to fix the protective package 001, the fourth electric cylinder 702 is started to control the cutting knife 701 to cut off the protective packaging 001, and the holding fork plate 203 is controlled to rotate 180 degrees again, so that the last PCB board 002 is located above the holding fork plate 203; then, the third motor 504 is started to control the glue sticking machine 505 to move from left to right to stick and fix the PCB board 002 packaging; then, the first electric cylinder 204 moves the holding fork plate 203 to the right to separate the protective packaging 001 and the PCB board 002 from the holding fork plate 203, The open discharge port at the rear of the mounting seat 101; finally, the fourth motor 605 is started to control the clamping plate 603 to move backward to protect the package 001, and add the end of the protective package 001 to the fork plate 203. At the same time, during this process, the top rod 804 unlocks the control arm 802 and the block 803, so that the rotating frame 301 can be rotated back to its original position. After completion, the clamping plate 603 moves forward to return to its original position, and the control arm 802 is locked by the top rod 804, and the rotating frame 301 is restricted again. Then the above steps are repeated to continue the packaging operation.
