[0045] Please refer to Figure 1 and Figure 2 The present application provides a specific embodiment of a full-automatic tin bar feeding machine, comprising a storage bin 1, a lifting mechanism 11, a tightening mechanism 12, a transmission mechanism 13 and a liquid level sensor 4.

[0046] The storage bin 1 is used for storing tin bars 5; the lifting mechanism 11 is arranged in the storage bin 1, and the telescopic end of the lifting mechanism 11 is used for stacking several layers of tin bars 5; the tightening mechanism 12 is arranged in the storage bin 1, and the telescopic end of the tightening mechanism 12 is used for tightening the second layer of tin bars 5 counted from the bottom; the transmission mechanism 13 is arranged in the storage bin 1 and located directly below the first layer of tin bars 5 counted from the bottom, the discharge end of the transmission mechanism 13 is in communication with the outside of the storage bin 1, and is used for conveying the tin bars 5 into the tin furnace 2; the liquid level sensor 4 is arranged in the tin furnace 2 to detect the liquid level of the tin liquid in the tin furnace 2 in real time; and the controller is electrically connected to the lifting mechanism 11, the tightening mechanism 12, the transmission mechanism 13 and the liquid level sensor 4.

[0047] In the present embodiment, please refer to Figure 3 and Figure 4 The lifting mechanism 11 is arranged in the storage bin 1, and comprises a lifting driver 11-a and a lifting plate 11-b, the lifting plate 11-b is connected to the output shaft of the lifting driver 11-a, that is, the lifting plate 11-b serves as the telescopic end of the lifting mechanism 11, and is used for supporting several layers of tin bars 5 stacked from the bottom, the output shaft of the lifting driver 11-a is telescopic and can drive the lifting plate 11-b to move, so as to realize the layer-by-layer falling of the several layers of tin bars 5 onto the transmission mechanism 13. The lifting driver 11-a is electrically connected to the controller to realize remote automatic control of the lifting mechanism 11.

[0048] In the present embodiment, please refer to Figure 3 and Figure 4, the pressing mechanism 12 is arranged in the storage bin 1 and is higher than the preset height of the lifting mechanism 11, the preset height is set according to the thickness of the tin strip 5, so that the pressing mechanism 12 corresponds to the second layer of tin strips 5 from bottom to top, the pressing mechanism 12 comprises a pressing driver 12-a and a pressing column 12-b, the pressing column 12-b is sleeved on the output shaft of the pressing driver 12-a, that is, the pressing column 12-b serves as the telescopic end of the pressing mechanism 12, the output shaft of the pressing driver 12-a drives the pressing column 12-b to move, so as to press the second layer of tin strips 5 from bottom to top on the bin wall of the storage bin 1, prevent the remaining tin strips 5 from falling when the first layer of tin strips 5 is discharged, and ensure that the several layers of tin strips 5 are discharged layer by layer. The pressing driver 12-a is electrically connected with the controller, so as to realize remote automatic control of the pressing mechanism 12.

[0049] In the embodiment, please refer to Figure 3 and Figure 4 , the transmission mechanism 13 is arranged in the storage bin 1 and is lower than the preset height of the lifting mechanism 11, the preset height can be set according to the thickness of the tin strip 5, so that the tin strip 5 falling on the transmission mechanism 13 does not interfere with the tin strip 5 on the telescopic end of the lifting mechanism 11, that is, the lifting plate 11-b. The transmission mechanism 13 can adopt an existing synchronous belt conveying mechanism, a chain 13-b transmission mechanism 13 or other driver components, and the structure is not unique, as long as the discharge end thereof is communicated with the outside of the storage bin 1. In this way, as long as the discharge end of the transmission mechanism 13 is aligned with the furnace opening of the tin furnace 2, the tin strip 5 can be discharged into the tin furnace 2.

[0050] In the embodiment, please refer to Figure 1 , the liquid level sensor 4 adopts a liquid level sensing probe, the liquid level sensing probe penetrates through the furnace opening of the tin furnace 2 and is inserted into the inside of the tin furnace 2, the insertion depth thereof can be set according to the preset tin liquid level, so that the bottom of the liquid level sensing probe just reaches the preset tin liquid level. In this way, when the liquid level sensing probe cannot sense the tin liquid, it indicates that the tin strip 5 needs to be put into the tin furnace 2.

[0051] Therefore, by using the above-mentioned full-automatic tin strip adding machine, the tin strip 5 can be automatically put into the tin furnace 2 in real time according to the liquid level sensor 4 in the tin furnace 2, and the tin liquid level in the tin furnace 2 can be accurately controlled to always maintain at a set height. On the one hand, the influence of manual difference is eliminated, the amount of tin slag is reduced, the wave peak is more stable, and the welding quality of the PCB board is greatly improved; on the other hand, the labor cost is saved.

[0052] On the basis of the above-mentioned embodiment, please refer to Figure 4 , the application also comprises a first light eye sensor 14 electrically connected with the controller, the first light eye sensor 14 is arranged in the storage bin 1 and is used for detecting whether the first layer of tin strips 5 from bottom to top exists.

[0053] Specifically, the first light eye sensor 14 is arranged at the same horizontal plane with the telescopic end of the lifting mechanism 11 or adjacent to the telescopic end of the lifting mechanism 11, so that when the telescopic end of the lifting mechanism 11 is retracted and the first light eye sensor 14 cannot sense the tin strip 5, the first light eye sensor 14 sends a signal to the controller, and the controller starts the transmission mechanism 13 to transport the tin strip 5 into the tin furnace 2 through the transmission mechanism 13. Therefore, the first light eye sensor 14 can be used to control the transmission mechanism 13 to be opened in time, so as to improve the efficiency of putting the tin strip 5 and improve the production efficiency of the PCB board.

[0054] Based on the above embodiment, the second light eye sensor 15 electrically connected with the controller is further included, the second light eye sensor 15 is arranged in the storage bin 1 and adjacent to the discharge end of the transmission mechanism 13, and is used to detect whether the tin strip 5 is discharged. Figure 4

[0055] Therefore, if the second light eye sensor 15 senses the tin strip 5, a signal is sent to the controller to complete a tin adding count, so as to facilitate the counting of the tin adding amount. If the second light eye sensor 15 cannot sense the tin strip 5 (or the time of continuously sensing the tin strip 5 exceeds the preset time), a tin strip 5 jam alarm is sent to the controller to remind the artificial to carry out the foolproof protection, so as to ensure that the subsequent tin strip 5 adding operation is normally carried out.

[0056] Considering the specific arrangement of the lifting mechanism 11, the clamping mechanism 12 and the transmission mechanism 13 in the storage bin 1, on the basis of the above embodiment, the storage bin 1 is provided with a front clamping plate 17 and a rear clamping plate 18 which are oppositely arranged and have a space 19 therebetween. The lifting mechanism 11 is fixed on the side of the rear clamping plate 18 away from the front clamping plate 17, and the telescopic end of the lifting mechanism 11 can move forward and backward through the rear clamping plate 18. The clamping mechanism 12 is fixed on the side of the rear clamping plate 18 away from the front clamping plate 17 and is higher than the lifting mechanism 11, and the telescopic end of the clamping mechanism 12 can move through the rear clamping plate 18. The transmission mechanism 13 is fixed in the space 19 and is arranged lower than the lifting mechanism 11, and the space 19 is in communication with the outside of the storage bin 1.

[0057] Specifically, as shown in Figure 3 The front clamping plate 17 and the rear clamping plate 18 are oppositely arranged in the storage bin 1, and the space 19 for placing the tin strip 5 is left between the front clamping plate 17 and the rear clamping plate 18. Preferably, the top ends of the front clamping plate 17 and the rear clamping plate 18 abut against the detachable top cover of the storage bin 1. The top cover is manually removed to facilitate the placement of the tin strip 5 in the space 19, that is, to facilitate the replenishment of the storage bin 1.

[0058] As shown in Figure 4 ​As shown, the side of the rear clamping plate 18 facing away from the front clamping plate 17 is the rear side of the rear clamping plate 18, and the other side of the rear clamping plate 18 facing the front clamping plate 17 is the front side of the rear clamping plate 18. A detachable first mounting seat 110 is arranged on the rear side of the rear clamping plate 18. A lifting driver 11-a is arranged on the first mounting seat 110. A lifting plate 11-b connected to the lifting driver 11-a can extend through the rear clamping plate 18 into the space 19 to support the multiple layers of tin bars 5 in the space 19 between the front clamping plate 17 and the rear clamping plate 18.

[0059] As shown in Figure 4 , a detachable second mounting seat 111 is arranged on the rear side of the rear clamping plate 18, and the second mounting seat 111 is arranged higher than the first mounting seat 110. A tightening driver 12-a is arranged on the second mounting seat 111. A tightening column 12-b connected to the tightening driver 12-a can extend through the rear clamping plate 18 into the space 19 to tightly press the second layer of tin bars 5 from bottom to top on the front clamping plate 17.

[0060] As shown in Figure 5 , a transmission mechanism 13 is arranged below the lifting plate 11-b in the space 19 between the rear clamping plate 18 and the front clamping plate 17. The lifting driver 11-a drives the lifting plate 11-b to retract away from the space 19, and the first layer of tin bars 5 from bottom to top falls into the transmission mechanism 13. The left and right ends of the space 19 are both open ends, that is, the space 19 is in communication with the outside of the storage bin 1, so that the transmission mechanism 13 can drive the tin bars 5 to move out of the storage bin 1.

[0061] Therefore, by arranging the lifting mechanism 11, the tightening mechanism 12, and the transmission mechanism 13 in the storage bin 1 in the above manner, the space 19 structure in the storage bin 1 can be reasonably utilized, and the three mechanisms can cooperate to orderly put the tin bars 5 into the tin furnace 2.

[0062] Further considering the stability of the tin bars 5, on the basis of the above embodiment, please refer to Figure 3 and Figure 4 , the lifting mechanism 11 is provided as two and symmetrically arranged at a first preset distance; and the tightening mechanism 12 is provided as two and symmetrically arranged at a second preset distance.

[0063] It can be understood that the tin bar 5 has a certain length, in order to ensure that the tin bar 5 is stably placed in the space 19 between the rear clamping plate 18 and the front clamping plate 17, at least two lifting mechanisms 11 are provided for supporting the tin bar 5, the two lifting mechanisms 11 are symmetrically arranged at a first preset distance, the first preset distance can be set according to the length of the tin bar 5, so that the two lifting mechanisms 11 are respectively supported at both ends of the tin bar 5, to ensure that the multiple layers of tin bar 5 are stably placed. Similarly, at least two tightening mechanisms 12 are also required to tighten the tin bar 5, the two tightening mechanisms 12 are symmetrically arranged at a second preset distance, to ensure that the multiple layers of tin bar 5 are tightly and stably placed, and to avoid tilting of the tin bar 5.

[0064] Preferably, the second preset distance is smaller than the first preset distance, so that the two tightening mechanisms 12 are located between the two lifting mechanisms 11, to avoid interference between the mounting seats of the tightening mechanism 12 and the lifting mechanism 11, thereby facilitating installation of the tightening mechanism 12 and the lifting mechanism 11.

[0065] Considering the specific arrangement of the first light eye sensor 14 in the storage bin 1, on the basis of the above embodiment, please refer to Figure 4 , the first light eye sensor 14 is fixed on the side of the rear clamping plate 18 away from the front clamping plate 17 and is located between the lifting mechanism 11 and the tightening mechanism 12 in the height direction, and the rear clamping plate 18 is provided with a first light source through hole corresponding to the position of the first light eye sensor 14.

[0066] Specifically, the first light eye sensor 14 is detachably arranged on the rear side of the rear clamping plate 18 through the third mounting seat 112, and the third mounting seat 112 is located between the first mounting seat 110 and the second mounting seat 111 in the height direction, that is, the first light eye sensor 14 is aligned with the first layer of tin bar 5 placed on the lifting plate 11-b, to ensure the accuracy of the first light eye sensor 14 sensing the first layer of tin bar 5. It should be noted that the first light source through hole is provided on the rear clamping plate 18 for the light source of the first light eye sensor 14 to emit onto the first layer of tin bar 5.

It should be noted that the third preset distance needs to be set according to the length of the left and right ends of the space 19, so that the discharge end of the chain 13-b is adjacent to the end of the space 19, that is, the end of the rear clamping plate 18 or the front clamping plate 17, and the motor 13-c is in electrical signal connection with the controller.

[0068] In this way, the motor 13-c drives one sprocket 13-a to rotate, the sprocket 13-a drives another sprocket 13-a to rotate through the chain 13-b, so as to tension the chain 13-b and drive the chain 13-b to rotate 360°, thereby realizing the conveying of the tin strip 5 by the chain 13-b. The sprocket 13-a and the chain 13-b conveying mechanism is suitable for conveying the slender tin strip 5, and the transmission ratio is accurate, and the tin strip 5 can be stably conveyed.
