[0030] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0031] Embodiment 1

[0032] like Figures 1 to 9 As shown, a continuous automatic feeding stamping die for battery conjoined terminals comprises a base 1 and a track 2, templates 3 are arranged on the left and right sides of the base 1, and limiting components 4 are symmetrically arranged on the templates 3, and the limiting components 4 comprise fixed blocks 41 arranged on the upper and lower sides of the template 3 and a slider 42 slidably arranged on the fixed block 41, and a positioning block a43 for primary positioning of the conjoined terminal and a positioning block b44 for secondary positioning of the conjoined terminal are slidably arranged on the slider 42, an air blowing component 5 is arranged at the left end of the track 2, a negative pressure component 6 is arranged at the right end of the track 2, and a pushing component 7 is arranged on the track 2, the conjoined terminal is driven to be transported to the right end of the track 2 by the air blowing component 5, the conjoined terminal is driven to move to the limiting component 4 by the pushing component 7, the conjoined terminal is kept to move smoothly by the negative pressure component 6, and the air blowing rate of the air blowing component 5 is adjusted by the pushing component 7.

[0033] It is worth mentioning here that a negative pressure component 6 is provided at the right end of the track 2, the one-piece terminal is driven to be transported to the right end of the track 2 by the air blowing component 5, and the one-piece terminal is driven to move to the limiting component 4 by the pushing component 7. The one-piece terminal is kept to move smoothly by the negative pressure component 6, the air blowing rate of the air blowing component 5 is adjusted by the pushing component 7, and the one-piece terminal is slid up and down and positioned by the positioning block a43 and the positioning block b44 to prevent the side wall from being damaged during stamping, thereby improving the product qualification rate, preventing the side wall of the one-piece terminal from being damaged, and keeping the one-piece terminal to move smoothly.

[0034] like Figure 3 As shown, a transmission section 21 , a pushing section 22 and a punching section 23 are arranged on the track 2 , and a proximity switch 9 is arranged on the right side wall of the pushing section 22 .

[0035] In this example, the proximity switch 9 senses whether the connected terminal reaches the specified position.

[0036] like Figure 3 As shown, the air blowing assembly 5 includes a plurality of air blowing holes 51 and an air pump opened on the transmission section 21. The air blowing holes 51 are inclined toward the pushing section 22, and the number of the air blowing holes 51 gradually decreases from the left end to the right end of the transmission section 21.

[0037] In this example, the number of air blowing holes 51 from the left end to the right end of the transmission section 21 gradually decreases, so that the air blowing force received by the connected terminal close to the pushing section 22 is smaller, and the connected terminal slowly enters the pushing section 22, preventing the connected terminal from quickly entering the pushing section 22 and hitting the side wall of the track 2 to cause damage, and preventing the proximity switch 9 from being damaged.

[0038] like Figure 4 As shown, the negative pressure assembly 6 includes a plurality of negative pressure holes 61 arranged on the pushing section 22 .

[0039] In this example, the conjoined terminal being pushed is adsorbed by the negative pressure hole 61 to make it translate stably, to prevent the cylinder from pushing too fast and causing it to pass over the positioning block a43 or the positioning block b44, thereby preventing the conjoined terminal from being pushed out of place.

[0040] like Figure 6 As shown, the slide block 42 is provided with a slide groove 421 for the positioning block a43 and the positioning block b44 to slide.

[0041] like Figure 6 As shown, the left and right side walls of the positioning block a43 and the positioning block b44 are both provided with sliding blocks 431, a return spring 45 is provided between the sliding block 431 and the slide groove 421, and the front ends of the positioning block a43 and the positioning block b44 are both provided with arc grooves 432.

[0042] In this example, by setting the sliding block 431, the positioning block a43 and the positioning block b44 slide in the sliding groove 421. When the connected terminal is stamped, the positioning block a43 and the positioning block b44 rise and fall simultaneously with the connected terminal to prevent the positioning block a43 and the positioning block b44 from causing damage to the side wall of the connected terminal.

[0043] like Figure 5 As shown, the pushing assembly 7 includes a cylinder 71 disposed on the base 1 and a pushing rod 72 driven by the cylinder 71, and the front and rear ends of the pushing rod 72 are both rounded.

[0044] In this example, the front and rear ends of the push rod 72 are rounded, so that the push rod 72 drives the control switch 10 to extend and retract during the pushing and retracting process.

[0045] like Figure 5As shown, a through hole 24 is provided on the track 2 for the push rod 72 to pass through, and a control switch 10 for controlling the air blowing rate of the air blowing assembly 5 is provided on the side wall of the through hole 24 .

[0046] In this example, the air blowing rate of the air blowing assembly 5 is controlled by the control switch 10. When the control switch is extended, the air blowing rate is low and the connected terminal moves slowly. When the control switch is retracted, the air blowing rate is high and the connected terminal moves quickly toward the pushing section 22.

[0047] like Figure 1 As shown, a discharge port 11 is provided at the upper end of the base 1 .

[0048] like Figure 1 As shown, a punch 8 is provided between the limiting assembly 4 and the track 2 .

[0049] The working process is as follows:

[0050] The manipulator puts the conjoined terminal on the transmission section 21, and the air blowing assembly 5 drives the conjoined terminal to move toward the pushing section 22. When the conjoined terminal enters the pushing section 22, the proximity switch 9 senses the conjoined terminal, and the cylinder 71 is started, driving the pushing rod 72 to push the conjoined terminal toward the stamping section 23. The conjoined terminal being pushed is adsorbed through the negative pressure hole 61 to make it translate stably, to prevent the cylinder from pushing too fast and causing it to pass over the positioning block a43 or the positioning block b44, to prevent the conjoined terminal from being pushed into place;

[0051] The edge of the one-piece terminal is stamped and formed by the punch 8, and the one-piece terminal enters the material frame through the discharge port 11. When the push rod 72 is pushed out, the control switch extends, the air blowing rate is low, and the one-piece terminal moves slowly. When the push rod 72 is retracted, the control switch retracts, the air blowing rate is high, and the one-piece terminal moves quickly to the pushing section 22.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
