[0002] The ejector pin is a key mechanical component in battery cap stamping equipment, used for demolding, positioning, and pressure transmission. It is usually installed at the bottom or side of the mold. During the stamping process of battery caps (such as positive and negative electrode caps and sealing plates of new energy batteries), the ejector pin pushes the formed cap out of the mold cavity through precise reciprocating motion, preventing the workpiece from sticking together and assisting in the completion of subsequent processes (such as trimming and punching).

[0003] However, the surface of traditional push rod devices is usually coated with a yellow layer, and the values ​​reflected by the photoelectric sensor through the yellow fixture have a large deviation, resulting in false signals.

[0004] This utility model addresses the above-mentioned problems by providing a combined push rod device for improving product yield. Utility Model Content

[0005] The purpose of this invention is to provide a combined push rod device to improve product yield, in order to solve the problem mentioned in the background art that the surface of the traditional push rod device is usually covered with a yellow coating, and the value of the detection photoelectric sensor reflected through the yellow fixture has a large deviation, resulting in false signals.

[0006] This invention addresses the aforementioned problems by improving upon the traditional top rod device, whose surface is typically coated with a yellow layer. This results in a significant deviation in the values ​​reflected by the photoelectric sensor through the yellow fixture, leading to misjudgments.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a combined top rod device for improving product yield, comprising a battery cap forming structure and a battery cap forming groove provided on the battery cap forming structure;

[0008] A insertion through hole is provided at the middle position of the pool cover forming groove;

[0009] A top rod connecting cap is provided at the middle position of the pool cover forming groove, and a top rod bottom connecting rod is provided at the bottom position of the top rod connecting cap. The outer sides of the top rod connecting cap and the top rod bottom connecting rod are covered with black coating material.

[0010] Preferably, a connecting groove for the connecting cap is provided at the middle position of the connecting cap on the top rod, and the connecting groove for the connecting cap and the connecting cap on the top rod are integral structures.

[0011] Preferably, a toggle adjustment knob is provided at the front side of the bottom connecting rod of the top rod, a lifting drive threaded column is provided at the middle position of the toggle adjustment knob, and a compression connecting conical head is provided at the upper side of the lifting drive threaded column.

[0012] Preferably, a connecting moving post is provided on the upper side of the extrusion connecting conical head, and a side connecting contact ball is provided at the middle position of the side end of the connecting moving post. The side connecting contact ball is rotatably connected to the connecting moving post through a connecting shaft provided on its side.

[0013] Preferably, a limiting connecting moving block is provided at the bottom side of the connecting moving column, a limiting moving groove is provided at the outer side of the limiting connecting moving block, and a reset connecting spring is provided at the middle position of the limiting moving groove.

[0014] Preferably, a side mounting connecting block is provided on the side of the battery cap molding structure, and the side mounting connecting block and the battery cap molding structure are an integral structure.

[0015] Preferably, a stamped connector is provided on the upper side of the battery cap molding structure, and both the stamped connector and the side mounting connector are provided with connecting thread grooves.

[0016] Preferably, a bottom drive cylinder is provided at the bottom position of the battery cap molding structure, and the bottom drive cylinder is electrically connected to an external power source.

[0017] Compared with the prior art, this utility model provides a combined push rod device to improve product yield, which has the following beneficial effects:

[0018] In the combined top rod device for improving product yield, a top rod upper connecting cap is set at the middle position of the pool cover forming groove, and a top rod bottom connecting rod is set at the bottom position of the top rod upper connecting cap. The outer side of the top rod upper connecting cap and the top rod bottom connecting rod is covered with a black coating material. The black coating material is a thin film of iron oxide generated by chemical oxidation. The black coating material improves the color of the fixture so that the value reflected by the detection photoelectric sensor through the black fixture is within the normal detection and recognition range. At the same time, the black coating material has excellent wear resistance and weather resistance.

[0019] In the combined push rod device for improving product yield, a toggle adjustment knob is provided at the front of the bottom connecting rod of the push rod. A lifting drive threaded column is provided at the middle of the toggle adjustment knob. A pressing connecting tapered head is provided at the upper side of the lifting drive threaded column. A connecting moving column is provided at the upper side of the pressing connecting tapered head. A side connecting contact ball is provided at the middle of the side end of the connecting moving column. The side connecting contact ball is rotatably connected to the connecting moving column through a connecting shaft provided at its side. A limit connecting moving block is provided at the bottom of the connecting moving column. A limit moving groove is provided on the outer side of the limit connecting moving block. A reset connection is provided at the middle of the limit moving groove. When the bottom connecting rod of the top rod is inserted into the insertion placement through hole, the adjustment knob can be turned to drive the lifting drive threaded column to rise. The rising of the lifting drive threaded column will compress the connecting moving column outward by squeezing the component force on the side of the conical slope of the connecting connection, ensuring that the side connecting contact ball can contact the inner side of the insertion placement through hole. The reverse operation can cause the connecting moving column to retract and reset due to the reset connecting spring. After the improvement of this utility model, it can effectively avoid the shaking damage caused by the gap between the bottom connecting rod of the top rod and the insertion placement through hole during stamping. At the same time, it can reduce the damage caused by sliding friction due to the tight fit, thereby effectively improving the practicality of the combined top rod device for improving product yield.
