Technical Field

[0001] The utility model relates to a packaging device, in particular to a packaging device for double-sided multi-layer circuit boards, belonging to the technical field of double-sided multi-layer circuit boards. Background Technique

[0002] A double-sided board has a dielectric layer in the middle and wiring layers on both sides. A multi-layer board has multiple wiring layers, with dielectric layers between every two layers, and the dielectric layers can be made very thin. A multi-layer circuit board has at least three conductive layers, two of which are on the outer surface, and the remaining one is integrated into the insulating board. The electrical connection between them is usually achieved through plated through holes on the cross-section of the circuit board. When packaging double-sided multi-layer circuit boards, a vacuum packaging machine is required.

[0003] However, when an operator installs the stretch film on the vacuum packaging machine, one hand needs to hold the stretch film to facilitate its fixation, and the placement position of the stretch film needs to be continuously adjusted during the operation, resulting in low installation efficiency, which is not conducive to improving the replacement speed of the stretch film. Content of the Utility Model

[0004] The purpose of the utility model is to provide a packaging device for double-sided multi-layer circuit boards to solve the above problems. The first clamping plate rotates to drive the limiting rod to separate from the fixing rod, so that the sleeve rod can be detached from the fixing rod, which is convenient for installing a new stretch film on the sleeve rod and is conducive to improving the replacement efficiency of the stretch film.

[0005] The utility model realizes the above purpose through the following technical solutions. A packaging device for double-sided multi-layer circuit boards includes a vacuum packaging machine body. Two symmetrically arranged support frames and a fixing mechanism are fixedly installed on the vacuum packaging machine body. A guiding mechanism and a limiting mechanism are rotated on the support frames. A rotating mechanism is clamped and installed on the limiting mechanism. The rotating mechanism includes a second clamping plate and a fixing rod. The second clamping plate is in contact with the support frame. A fixing rod is fixedly installed on the second clamping plate. A limiting rod is threadedly connected to the fixing rod. A first clamping plate is fixedly connected to the limiting rod. Clamping rods are fixedly connected to both the first clamping plate and the second clamping plate. A number of groups of balls are rotated on the fixing rod. A sleeve rod is sleeved on the fixing rod. The balls are in rolling connection with the sleeve rod.

[0006] Preferably, the cross-sectional diameters of both the first clamping plate and the second clamping plate are larger than the cross-sectional diameter of the sleeve rod, and the cross-sectional diameter of the sleeve rod is larger than the cross-sectional diameter of the fixing rod.

[0007] Preferably, both ends of the sleeve rod are rotatably connected to the first clamping plate and the second clamping plate, and the clamping rod is clamped with the support frame.

[0008] Preferably, the limiting mechanism includes a rotating block and a lead screw. The lead screw is rotatably connected to the support frame. A rotating block is fixedly installed at the top end of the lead screw. A rotating shaft is threadedly connected to the lead screw. A clamping block is fixedly connected to the bottom end of the rotating shaft. A gasket is adhered to the clamping block. A clamping groove and a sliding groove are provided on the support frame.

[0009] Preferably, a clamping rod is snap-fitted in the clamping groove, and the gasket is snap-fitted with the clamping rod.

[0010] Preferably, the clamping block and the gasket slide in the sliding groove, and the bottom ends of the clamping block and the gasket are in contact with the inner wall of the support frame.

[0011] Preferably, the guiding mechanism includes a guiding rod and a supporting block. The two support frames are both fixedly connected with a supporting block. A connecting shaft is fixedly installed on the supporting block. A guiding rod is rotatably connected to the connecting shaft. A rotating rod is rotatably connected to the support frame.

[0015] The beneficial effects of the present utility model are as follows: When the stretch film installed on the sleeve rod is used up, the operator can rotate the limiting mechanism by hand. When the limiting mechanism slides in the support frame, it can be separated from the clamping rod, and the sleeve rod can be supported to remove the clamping rod from the support frame. Then, rotate the first clamping plate by hand. The first clamping plate drives the limiting rod to rotate in the fixed rod, and then the limiting rod rotates out of the fixed rod. Since there are several groups of rolling balls rotating on the fixed rod, when the sleeve rod is removed, the sleeve rod slides to drive the rolling balls to rotate, thereby facilitating the reduction of the friction area between it and the fixed rod and being beneficial to improving the disassembly efficiency of the sleeve rod. After reinstalling the new stretch film on the sleeve rod, then sleeving the sleeve rod on the fixed rod and rotating the first clamping plate to reinstall the limiting rod in the fixed rod, thus facilitating the rapid replacement of the stretch film.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-7As shown in the figure, a packing device for a double-sided multi-layer circuit board includes a vacuum packaging machine body 1. Two symmetrically arranged support frames 2 and a fixing mechanism 6 are fixedly installed on the vacuum packaging machine body 1. A guiding mechanism 3 and a limiting mechanism 4 are rotatably arranged on the support frame 2. A rotating mechanism 5 is snap-fitted on the limiting mechanism 4. The rotating mechanism 5 includes a second clamping plate 503 and a fixing rod 504. The second clamping plate 503 contacts the support frame 2. A fixing rod 504 is fixedly installed on the second clamping plate 503. A limiting rod 506 is threadedly connected to the fixing rod 504. A first clamping plate 502 is fixedly connected to the limiting rod 506. Clamping rods 507 are fixedly connected to both the first clamping plate 502 and the second clamping plate 503. A number of groups of balls 505 are rotatably arranged on the fixing rod 504. A sleeve rod 501 is sleeved on the fixing rod 504. The balls 505 are in rolling connection with the sleeve rod 501.

[0026] As a technical optimization scheme of the present utility model, the cross-sectional diameters of both the first clamping plate 502 and the second clamping plate 503 are larger than the cross-sectional diameter of the sleeve rod 501, and the cross-sectional diameter of the sleeve rod 501 is larger than the cross-sectional diameter of the fixing rod 504. The sleeve rod 501 is sleeved on the fixing rod 504. When the stretching film drives the sleeve rod 501 to rotate, the sleeve rod 501 can drive the balls 505 to rotate within the fixing rod 504.

[0027] As a technical optimization scheme of the present utility model, both ends of the sleeve rod 501 are rotatably connected to the first clamping plate 502 and the second clamping plate 503. The clamping rod 507 is snap-fitted with the support frame 2, and the support frame 2 limits the clamping rod 507, thereby facilitating the support of the stretching film installed on the sleeve rod 501.

[0028] As a technical optimization scheme of the present utility model, the limiting mechanism 4 includes a rotating block 401 and a lead screw 402. The lead screw 402 is rotatably connected to the support frame 2. A rotating block 401 is fixedly installed at the top end of the lead screw 402. A rotating shaft 403 is threadedly connected to the lead screw 402. A clamping block 404 is fixedly connected to the bottom end of the rotating shaft 403. A gasket 405 is adhered to the clamping block 404. A card slot 406 and a sliding slot 407 are provided on the support frame 2. The rotating block 401 drives the lead screw 402 to rotate, so that the rotating shaft 403 drives the clamping block 404 to slide into the sliding slot 407, and thus the gasket 405 is separated from the clamping rod 507.

[0029] As a technical optimization scheme of the present utility model, the clamping rod 507 is snap-fitted at the card slot 406 part, and the gasket 405 is snap-fitted with the clamping rod 507. The card slot 406 limits the clamping rod 507, and thus can support the weight generated by the stretching film.

[0030] As a technical optimization solution of the utility model, a block 404 and a gasket 405 are slidingly arranged in the slide groove 407, and the bottom ends of the block 404 and the gasket 405 are in contact with the inner wall of the support frame 2. When the block 404 drives the gasket 405 to slide, the gasket 405 can be engaged with the top of the clamping rod 507, thereby causing the block 404 to limit the clamping rod 507.

[0031] As a technical optimization solution of the utility model, the guide mechanism 3 includes a guide rod 301 and a support block 303. The two support frames 2 are fixedly connected with the support blocks 303. The support blocks 303 are fixedly installed with a connecting shaft 304. The connecting shaft 304 is rotatably connected with the guide rod 301. The support frame 2 is rotatably connected with a rotating rod 302. The stretch film passes around the guide rod 301 and then around the rotating rod 302, so that it is in a straightened state when sliding, thereby facilitating improving its use effect.

[0032] As a technical optimization solution of the utility model, the guide rod 301 is rotatably connected to the support block 303, and the height of the guide rod 301 is greater than the height of the rotating rod 302 and the sleeve rod 501. The guide rod 301 stretches the stretch film, which helps to prevent the stretch film from becoming loose when sliding.

[0033] As a technical optimization solution of the utility model, the fixing mechanism 6 includes a mounting plate 601 and an operating table 603. The operating table 603 is fixedly connected to the vacuum packaging machine body 1, and the mounting plate 601 is fixedly connected to the operating table 603. The mounting plate 601 is rotatably connected to a guide wheel 602. After placing the circuit board to be packaged on the vacuum packaging machine body 1, the circuit board can be vacuum-packed by stretching film, and the vacuum-packed circuit board can be moved to the operating table 603 by pulling the pallet.

[0034] As a technical optimization solution of the utility model, the two mounting plates 601 are symmetrically arranged, and the plurality of guide wheels 602 are equidistantly arranged. When the pallet slides on the operating table 603, the pallet can be guided by the guide wheels 602 rotating inside the mounting plates 601.

[0035] When the utility model is in use, first, the operator can rotate the rotating block 401 by hand. The rotating block 401 drives the lead screw 402 to rotate in the two support frames 2 fixed on the vacuum packaging machine body 1. The rotating shaft 403 threaded on the lead screw 402 drives the clamping block 404 to slide towards the chute 407 provided in the support frame 2. When the clamping block 404 slides, the gasket 405 fixed on its inner wall can be separated from the clamping rod 507. Then, the sleeve rod 501 can be lifted by hand to take out the clamping rod 507 from the clamping groove 406 provided in the support frame 2. Rotate the first clamping plate 502 by hand. The first clamping plate 502 drives the limiting rod 506 to rotate in the fixed rod 504, so that the limiting rod 506 rotates out of the fixed rod 504. Since several groups of balls 505 are rotated on the fixed rod 504, when the sleeve rod 501 is disassembled, the sleeve rod 501 slides to drive the balls 505 to rotate, which is convenient for reducing the friction area between it and the fixed rod 504 and is beneficial to improving the disassembly efficiency of the sleeve rod 501. After reinstalling the new stretch film on the sleeve rod 501, then sleeved the sleeve rod 501 on the fixed rod 504 and rotate the first clamping plate 502 to reinstall the limiting rod 506 in the fixed rod 504, which is convenient for quickly replacing the stretch film. Install the clamping rod 507 into the support frame 2 and rotate the rotating block 401 again to limit the clamping rod 507 by the clamping block 404. Wind the stretch film around the guide rod 301 and the rotating rod 302. When the stretch film slides, it drives the guide rod 301 to rotate along the coupling shaft 304 installed on the support block 303, so that the stretch film is in a straightened state when installed in the vacuum packaging machine body 1, which is beneficial to preventing it from loosening. Stack the circuit boards to be packaged and place them on the pallet. Move the pallet from the operating table 603 to the vacuum packaging machine body 1. Turn on the control switch of the vacuum packaging machine body 1 to heat the stretch film. When the stretch film slides down and covers the circuit boards, it can vacuum pack the circuit boards. Pull the pallet to move the packaged circuit boards to the operating table 603. Two mounting plates 601 are fixed on the operating table 603. The guide wheels 602 rotating in the mounting plates 601 guide the pallet, which can improve the sliding effect of the pallet.
