Description

Technical Field

[0001] This utility model relates to the field of assembly machines, and specifically to a product liquid injection detection device for assembly machines. Background Technology

[0002] In existing technologies, the production equipment for battery and capacitor products such as lithium batteries, aluminum electrolytic capacitors, and supercapacitors is an assembly machine. This manufacturing process suffers from significant efficiency bottlenecks and testing lags. Taking aluminum electrolytic capacitors as an example, after the assembly machine completes all processes, the capacitors are transported to other machines for electrical testing. Only then can it be determined whether the product has been properly injected with electrolyte. This series-process production mode is inherently lagging, meaning that defective products without electrolyte injection must go through all processes before being identified. This not only wastes raw materials but also increases rework costs. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, the technical problem this invention aims to solve is how to perform electrolyte testing on capacitor products during the assembly process. The specific technical solution is as follows:

[0004] A product electrolyte injection detection device for an assembly machine includes a detection seat, a pneumatic finger, a left test clamp, a right test clamp, a probe, and a capacitance analyzer. A capacitor product rotates with a turntable to the detection station, where the detection seat is installed. A pneumatic finger is installed at the bottom of the detection seat. A left test clamp is installed at the left end of the pneumatic finger, and a right test clamp is installed at the right end. The pneumatic finger drives the left and right test clamps to retract and clamp the product guide pin. The probe is installed on either the left or right test clamp and contacts the product guide pin. The probe's tail is electrically connected to the capacitance analyzer via a wire. When the capacitance analyzer detects that the capacitance loss value does not meet a set value, it determines that the capacitor product has not been injected with electrolyte.

[0005] As a preferred embodiment of this utility model, the probe has two rows of leads that contact the positive and negative electrodes of the product respectively. When the two rows of probes are installed on the left test clamp, a pad is installed on the right test clamp accordingly, or when the two rows of probes are installed on the right test clamp, a pad is installed on the left test clamp accordingly. The position of the pad corresponds to the position of the probe.

[0006] As a preferred embodiment of this utility model, a spring is fitted on the outer periphery of the probe, and the probe and the pad make elastic contact with the product guide needle.

[0007] As a preferred embodiment of this invention, each column of probes has at least two probes.

[0008] As a preferred embodiment of the present invention, a calibrating block is installed at the bottom of the left test clamp or the right test clamp, and correspondingly, the right test clamp or the left test clamp is provided with a clearance groove for the calibrating block to extend into, and the calibrating block is provided with a V-shaped calibrating groove for aligning the guide pin.

[0009] Beneficial effects: When the product electrolyte injection detection device of this utility model assembly machine is working, the capacitor product rotates with the turntable to reach the detection station. The pneumatic finger drives the left and right test clamps to retract and clamp the product guide pin. The probe contacts the product guide pin. If the capacitance loss meter detects that the capacitance loss value does not meet the set value, it is determined that the capacitor product has not been injected with electrolyte. Detecting whether the product is properly injected with electrolyte during the assembly process can promptly detect product defects and reduce rework costs. Attached Figure Description

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0014] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figures 1-3As shown, a product electrolyte injection detection device for an assembly machine includes a detection seat 1, a pneumatic finger 2, a left test clamp 3, a right test clamp 4, a probe 5, and a capacitance loss meter 6. The capacitor product rotates with a turntable 7 to the detection station, where the detection seat 1 is installed. The detection seat 1 can be mounted on the assembly machine via a bracket. The pneumatic finger 2 is installed at the bottom of the detection seat 1. The left test clamp 3 is installed at the left finger position of the pneumatic finger 2, and the right test clamp 4 is installed at the right finger position. The pneumatic finger 2 drives the left and right test clamps 3 and 4 to retract and clamp the product guide pin. The probe 5 is installed on either the left or right test clamp 3. When the left or right test clamps 3 and 4 retract and clamp the product guide pin, the probe 5 contacts the product guide pin. The tail of the probe 5 is electrically connected to the capacitance loss meter 6 via a wire (not shown). When the capacitance loss meter 6 detects that the capacitance loss value does not meet the set value, it determines that the capacitor product has not been injected with electrolyte.

[0017] In some embodiments, the probe 5 has two rows of probes that respectively contact the positive and negative electrodes of the product, i.e., one row contacts the positive electrode and the other row contacts the negative electrode. When the two rows of probes 5 are installed on the left test clamp 3, a pad 8 is correspondingly installed on the right test clamp 4. Alternatively, in this embodiment, when the two rows of probes are installed on the right test clamp 4, a pad 8 is correspondingly installed on the left test clamp 3, and the position of the pad 8 corresponds to the position of the probe 5.

[0018] In some embodiments, a spring 9 is fitted around the outer periphery of the probe 5, and the probe 5 and the pad 8 make elastic contact with the product guide needle. There are at least two probes 5 in each row.

[0019] In some embodiments, a calibrating block 10 is installed at the bottom of the left test clamp 3 or the right test clamp 4. Correspondingly, the right test clamp 4 or the left test clamp 3 is provided with a recess for the calibrating block to extend into, and the calibrating block 10 is provided with a V-shaped calibrating groove to align the guide pin. In this embodiment, the calibrating block 10 is installed at the bottom of the left test clamp 3, and the right test clamp 4 is provided with a recess for the calibrating block to extend into. The V-shaped calibrating groove ensures that the capacitor guide pin is aligned and contacts the probe.

[0020] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
