Description

Technical Field

[0001] The utility model belongs to the technical field of PCB production, and particularly relates to an adjustable material tray structure with stable feeding. Background Art

[0002] Connectors are basic components widely used in PCBs. In the SMT process, connectors are gathered on connector trays. When in use, the corresponding connectors are attached to the corresponding positions on the PCB by the patch mechanism. The weight of the entire tray of connectors exceeds the feeding pulling force of the feeding motor. During the feeding process, personnel need to manually pull the materials out of the tray. If the materials are not manually loosened in time during the operation, the machine will not feed the materials into place and an alarm will be issued, which will cause the material picking position to shift, and even problems with identifying the thrown materials and the patch offset after the furnace will occur, thereby reducing production efficiency and increasing costs. Utility Model Content

[0003] The purpose of the present utility model is to provide an adjustable material tray structure with stable feeding, so as to solve the problem proposed in the above background technology that personnel need to manually pull the material out of the material tray during feeding. If the material is not manually loosened in time during operation, the machine will not feed the material into place and an alarm will be issued, which will cause the material picking position to be offset, and even subsequent problems will occur in identifying the thrown material and the offset of the patch after the furnace, thereby reducing production efficiency and increasing costs.

[0004] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip.

[0005] The above scheme is adopted to achieve overall fixation by setting fixing bolts, and the outer support tube and inner support plate are used in combination to achieve height support adjustment, which is convenient for personnel to adjust and use according to needs. The triangular support rod is used in combination with the material tray, and the two ends of the triangular support rod are detachably connected to the connecting shaft through a cross connecting seat. The connecting shaft rotates through a rotating shaft and is used in combination with a one-way rotating bearing. When the material is fed, the bearing slides, reducing the friction between the material tray and the material rack, ensuring smooth feeding and preventing reverse sliding, effectively replacing manual pulling operations and improving production stability.

[0006] As a preferred embodiment, a plurality of limit blocks are fixed to the inner wall of the outer support tube, and a limit groove is provided on the side of the inner support plate, and the limit blocks and limit grooves at corresponding positions are used in conjunction with each other.

[0007] By adopting the above solution, the limit block is used in conjunction with the limit groove, which can not only ensure the stability of the inner support plate sliding up and down, but also prevent the inner support plate from detaching from the outer support tube when sliding upward, thereby achieving a limiting and anti-detachment effect.

[0008] As a preferred embodiment, a pushing disk is movably mounted on the inner wall of the cross connecting groove on the connecting shaft, and a strip-shaped hole for the pushing disk to slide is opened on the connecting shaft.

[0009] By adopting the above solution, the push plate is used in conjunction with the strip hole. When the triangular support rod needs to be disassembled, it is only necessary to operate the push plate to drive the cross connecting seat to move, so that the cross connecting seat can be separated from the cross connecting groove, thereby realizing the disassembly operation of the triangular support rod and improving the convenience of operation and disassembly.

[0010] As a preferred embodiment, a first spring is fixedly installed inside the accommodating groove at the end of the triangular support rod, and the first spring is fixedly connected to the cross connecting seat. A telescopic rod is provided inside the first spring, and the telescopic rod is fixed inside the accommodating groove and fixedly connected to the cross connecting seat.

[0011] By adopting the above solution, the first spring is combined with the telescopic rod. The elasticity of the first spring can drive the cross connection seat to be quickly inserted into the cross connection groove. The telescopic rod can support and guide the movement of the cross connection seat, improve the smoothness of movement, prevent shaking, and thereby achieve stable assembly and locking between the triangular support rod and the connecting shaft.

[0012] As a preferred embodiment, a positioning rod is slidably installed on the positioning plate, a pull ring is fixedly installed on one end of the positioning rod, a second spring is fixedly installed between the pull ring and the positioning plate, and a positioning groove is provided on the outer surface of the triangular support rod for inserting the other end of the positioning rod.

[0013] By adopting the above solution, the positioning rod is used in conjunction with the second spring. The elasticity of the second spring can drive the positioning rod to be quickly inserted into the positioning groove, thereby locking the positioning disk and limiting the material disk to prevent the material from shifting laterally.

[0014] As a preferred embodiment, the bearing is a one-way rotating bearing.

[0015] By adopting the above solution and setting a one-way rotating bearing, the forward feeding is smooth and the reverse sliding is prevented, which can reduce the burden on the feeder and enable the feed to be easily placed.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The adjustable feed tray structure with stable feeding is fixed as a whole by setting fixing bolts, and the outer support tube and the inner support plate are used together to realize height support adjustment, which is convenient for personnel to adjust and use according to needs. The triangular support rod is used with the feed tray, and the two ends of the triangular support rod are detachably connected to the connecting shaft through a cross connecting seat. The connecting shaft rotates through a rotating shaft and is used in conjunction with a one-way rotating bearing. When the material is fed, the bearing slides, reducing the friction between the feed tray and the material rack, ensuring smooth feeding and preventing reverse sliding, effectively replacing manual pulling operations and improving production stability.

[0027] The overall fixation is achieved by setting the fixing bolts 3, and the outer support tube 1 and the inner support plate 4 are used together to achieve height support adjustment, which is convenient for personnel to adjust and use according to needs. The triangular support rod 8 is used in conjunction with the material tray 9. The two ends of the triangular support rod 8 are detachably connected to the connecting shaft 7 through the cross connecting seat 11. The connecting shaft 7 rotates through the rotating shaft and is used in conjunction with the one-way rotating bearing 6. When the material is fed, the bearing 6 slides, reducing the friction between the material tray 9 and the material rack, making the feeding smooth and preventing reverse sliding, effectively replacing manual pulling operations and improving production stability.

[0028] Several limit blocks 12 are fixed to the inner wall of the outer support tube 1, and a limit groove is provided on the side of the inner support plate 4. The limit blocks 12 at the corresponding positions are used in conjunction with the limit grooves.
