Technical Field

[0001] The utility model belongs to the technical field of object transfer equipment, and specifically relates to a multi-size adaptable universal PCB carrier device. Background Art

[0002] Molding is one of the important machining processes of PCB. Its main purpose is to perform shape processing on the circuit board by punching, milling, V-CUT, beveling, etc. according to the requirements of engineering data after the PCB production process is completed. The existing production process of the molding process includes: gong board → framing → trolley transfer → framing removal → finished product A side V-CUT → framing → trolley transfer → framing removal → B side finished product V-CUT → framing → trolley transfer → framing removal → finished product cleaning.

[0003] In the prior art, carrier carts are used for transportation from the cleaning section after molding to the final packaging section, and the universal testing machines used in the middle testing section have two types: small table and medium table, which are respectively matched with circuit boards of different sizes after molding. Correspondingly, in order to adapt to finished boards of different sizes and universal testing machines, conventional carrier carts also have two different size models, resulting in that the same carrier cart cannot be used for circuit boards of different sizes, and cannot be used for docking with the small table and the medium table of the universal testing machine at the same time, and is not universal; and the table of the existing carrier cart is usually a flat structure, which cannot be docked with the universal testing machine, AV I inspection machine, board bending and leveling machine and packaging counting machine; in addition, the existing carrier carts are usually transported by manual pushing, with a low degree of automation, resulting in low transportation efficiency and high labor intensity.

[0034] In the above, the size of the table top of the placement table is adjusted by sliding the limiting member, and the change in the table top size makes it adaptable to the use of circuit boards of different sizes and to the docking use of tables of different sizes in a universal testing machine.

[0035] In this embodiment, the trolley 1 includes a base 12, a bracket 13 arranged at the rear end of the base 12, and a placement table 10 arranged on the base 12. The rollers 11 are arranged at the bottom of the base 12, and the upper rear side of the bracket 13 is provided with an armrest 14 to facilitate pushing or pulling the trolley by hand.

[0036] Preferably, the limiting member 2 includes a bottom plate 21 slidably disposed on the placement table 10, a front baffle plate 22 perpendicular to the front end of the bottom plate 21, and a top plate 23 perpendicularly disposed on the rear side of the upper end of the front baffle plate 22, that is, the bottom plate 21 is in contact with the placement table, and in the process of its sliding, it drives the front baffle plate 22 to move forward and backward. The front baffle plate serves as a backrest after the circuit board is placed. After the bottom plate and the front baffle plate move forward, they will cover a portion of the placement table 10, thereby changing the size of the exposed part of the table top of the placement table.

[0037] Preferably, the bracket 13 is provided with an opening 15 for the bottom plate 21 and the top plate 23 to slide through backward, and the lower end of the opening 15 is provided with a first connecting rod 16 that is flush with the height of the placement table 10, and the bottom plate 21 is fixedly connected to the first connecting rod 16 by screws; the bottom plate 21 is provided with two first long holes 24 extending along its length and for the screws to pass through, and the top of the first connecting rod 16 is provided with two threaded holes 17 that correspond one to one with the first long holes 24 and are threadedly connected to the screws, so that after the limit member is adjusted front and back and moved into place, the bottom plate is fixed by the screws passing through the first long holes and cooperating with the screw holes, so that the limit member 2 cannot move during use.

[0038] Preferably, a second connecting rod 18 is provided at the upper end of the opening 15, and two connecting plates 25 are extended backward from the rear end of the top plate 23. The connecting plates 25 are fixedly connected to the second connecting rod 18 by screws.

A threaded hole 17 corresponding to the second elongated hole 16 and threadedly connected to the screw is provided at the bottom of the second connecting rod 18. Therefore, after the limit member is adjusted frontward and rearward and moved into position, the connecting plate is fixed by the screw passing through the second elongated hole and then cooperating with the screw hole, and cooperating with the limit structure of the bottom plate to form a structure of upper and lower fixed limit positions. When the position of the limit member needs to be adjusted again, it is only necessary to loosen the screws, and retighten the screws after the adjustment is completed.

[0039] In this embodiment, the limit member 2 also includes an inverted U-shaped stretching frame 27, which is arranged at the bottom of the connecting plate 25, and a through hole 271 is provided on the stretching frame 27 at a position corresponding to the second long hole 26.

[0041] In one embodiment, a vertically arranged reinforcing plate 29 is provided between the bottom plate 21 and the top plate 23 and the front baffle 22 to improve the overall strength of the limiting member and prevent it from deformation.

[0042] Preferably, the placement table 10 is composed of a plurality of support rods 19 arranged at intervals to the left and right, the support rods 19 being right-angled, one end of the support rods 19 being connected to the front end surface of the base 12, and the other end being connected to the bracket 13 and the first connecting rod 16; in the secondary structure, the placement table is a toothed structure having a plurality of docking gaps, and docking gaps with various types of equipment are formed between adjacent support rods 19 to meet the docking needs of the carrier trolley with various types of equipment, solving the problem that the table structure of the existing carrier trolley cannot be docked with a universal testing machine, AVI inspection machine, plate bending and leveling machine, and packaging counting machine; at the same time, when manufacturing the PCB carrier device, the spacing between adjacent support rods can be adjusted to achieve the minimum applicable carrier width to meet actual needs.

[0043] In one embodiment, the thickness of the support rod 19 is preferably 10 mm, and the distance between two adjacent support rods 19 is 45 mm, so that the minimum carrier width is 90 mm.

[0045] In one embodiment, the height of the AGV is 300 mm, and the lifting height of the AGV is 50 mm. In order to enable the AGV to lift the PCB carrier device upward, the bottom of the base 12 is designed to be 320 mm above the ground, that is, when the AGV is not lifted, the top is 20 mm away from the bottom of the base. After the AGV is lifted to a height of 50 mm, the AGV can lift the PCB carrier device 30 mm off the ground for suspended transportation.

[0046] In one embodiment, a cross mark 123 is provided in the middle of the bottom of the base 12, and a QR code is pasted at the cross mark position, so that after the AGV enters the PCB carrier device, the purpose of docking and alignment is achieved by reading the QR code information.
