Problems solved by technology
[0008] The existing automatic tin feeding structure is an open-loop system, and it is impossible to measure the actual length of the tin wire sent
If slippage occurs, it will cause a large deviation between the actual length of the tin wire and the set length of the tin wire, so that the purpose of accurate tin delivery cannot be achieved

Embodiment Construction
[0022] see figure 2 , the preferred embodiment of the present invention includes a wire chute 2, a wire feeding motor 4, a fixed frame 5 and a tin feeding tube 6, wherein a photoelectric encoder 7 is arranged between the tin feeding tube 6 and the wire feeding motor 4 , the photoelectric encoder 7 is fixed on the fixed frame 5 through the photoelectric encoder shaft sleeve 8, the wire feeding motor 4 is also fixed on the fixed frame through the wire feeding gear 3, and the photoelectric encoder contains a single-chip microcomputer or PLC, The single-chip microcomputer or PLC receives instructions to obtain the parameters of the tin-feeding speed or the tin-feeding length, thereby calculating the distance that the wire-feeding motor 4 should rotate, and the single-chip microcomputer or PLC drives the wire-feeding motor 4 to rotate accordingly, and drives the wire-feeding motor 4 to be socketed on the motor The gear rotates, and the tin wire is driven to move through the meshin...

The invention relates to an automatic tin conveying system, which comprises a wire traveling groove, a wire conveying motor, a fixing frame and a tin feeding tube. The automatic tin conveying system is characterized in that a photoelectric encoder is arranged between the tin feeding tube and the wire conveying motor and fixedly sleeved on the fixing frame by a photoelectric encoder shaft, the wire conveying motor is also fixed onto the fixing frame by a wire conveying gear, a single chip microcomputer or a PLC (programmable logic controller) is arranged in the photoelectric encoder, instructions are received by the single chip microcomputer or the PLC, parameters of the tin conveying speed or the length of conveyed tin are obtained, accordingly, the required rotation distance of the motor is computed, the single chip microcomputer or the PLC drives the motor to rotate according to the required rotation distance, the gear sleeved on the motor is driven to rotate, and a tin wire is driven to move by the aid of meshed friction force of the gear and the tin wire. The length of the actually conveyed tin wire can be measured and fed back via the tin conveying system, and errors caused by slipping of the gear and the tin wire which are meshed are avoided.
Description
technical field [0001] The invention relates to an automatic tin feeding system, and further relates to a tin feeding system capable of measuring and controlling the tin feeding length. Background technique [0002] As an important production process, soldering is widely used in different products. With the rapid development of product design, the requirements for soldering are also increasing. The size of tin spots or tin seams directly affects the performance of products. This requires accurate and reliable control of the minimum amount of tin feeding. The most typical example is that some high-end smartphones require the minimum amount of tin feeding to be within 0.3mm. [0003] There are two main ways to control the amount of tin feeding: manual tin feeding and automatic tin feeding. [0004] Manual tin feeding mainly relies on workers to manually feed tin, through visual inspection of welding conditions, and adjustments based on experience. Usually well-trained worke...
