[0003] In the related art, the clamp pin on the cell winding equipment cannot ensure parallelism when being assembled. When the parallelism of the discharging clamp needle changes, not only will the diaphragm be clamped and damaged, causing internal damage to the bare cell and quality risks, but also the bare cell cannot be unloaded from the circular winding needle, causing equipment failure. CONTENT OF THE UTILITY MODEL

[0005] To solve the above technical problems, in a first aspect, the present application provides a winding machine clamp pin checking device, comprising:

[0006] A support, the support comprising a first guide rod, a second guide rod and a connecting block, the first guide rod and the second guide rod being arranged in parallel along a first direction, the connecting block being arranged on the same side of the first guide rod and the second guide rod; a first through hole is arranged on the connecting block along a second direction, and the first through hole is configured to fix a first clamp pin;

[0008] In the technical scheme of the present application, after the base is moved to a preset position relative to the first guide rod and the second guide rod, the corresponding first clamp pin is fixed in the first through hole, and the second clamp pin is fixed in the second through hole. At this time, it is observed whether the distance of the base relative to the same side of the first guide rod and the second guide rod is the same. When the distance is the same, the second clamp pin can form a parallel structure relative to the first clamp pin under the limitation of the base. At this time, under the joint limitation of the support and the base, the first clamp pin and the second clamp pin remain parallel, so that the corresponding first clamp pin and second clamp pin can be fixed to the cell winding equipment.

[0009] In some embodiments, a scale is arranged on the first guide rod and the second guide rod in the first direction. In this way, it is convenient to observe the distance of the base relative to the same side of the first guide rod and the second guide rod.

[0012] Since the adapter blocks are detachably connected to the first through hole or the second through hole, during use, different models of adapter blocks can be replaced according to the diameter size of the pin, so as to adapt to all models of pins.

[0013] In some embodiments, the inner wall of the first through hole is provided with a first clamping groove and / or a second clamping groove, and the first clamping groove and the second clamping groove are distributed in a diameter direction parallel to the first direction.

[0016] In some embodiments, the first clamping groove and the second clamping groove both extend in an axial direction.

[0017] The first clamping groove has a first open end and a first closed end, and the second clamping groove has a second open end and a second closed end, and the first open end and the second open end are located on opposite sides of the adapter block in the second direction.

[0018] In this way, when the protruding portion abuts against the first closed end during fixing the adapter block into the corresponding first through hole, the adapter block can be prevented from sliding out of the first through hole.

The third open end and the fourth open end are located on opposite sides of the base along the second direction.

[0024] In this way, when the adapter block is fixed into the corresponding second through hole, the adapter block can be prevented from sliding out of the second through hole when the protrusion abuts against the third closed end.

[0025] In some embodiments, the winding machine needle clamp calibration device further includes a detection element disposed on the base and configured to detect the levelness of the base. This facilitates the detection of the levelness of the base.

[0026] In some embodiments, the winding machine needle clamping verification device further includes a fastener, which is slidably disposed on the first guide rod and / or the second guide rod;

[0027] When the base moves to a preset position relative to the first guide rod, the fastener abuts against the base and is fixed to the first guide rod and / or the second guide rod. This facilitates fixing the base to the preset position of the bracket.

[0028] In some embodiments, the fastener includes a snap-fit ​​and a rotating torque;

[0029] The buckle is slidably disposed on the first guide rod and / or the second guide rod, and the rotation knob is connected to the buckle;

[0030] When the rotating torque rotates relative to the latch, it can abut against the first guide rod and / or the second guide rod. Thus, by rotating the rotating torque so that it abuts against the corresponding first or second guide rod, the latch can be secured to the first or second guide rod.

[0031] In some embodiments, the first guide rod is provided with a sliding groove along a first direction, and the base is provided with a first guide hole and a second guide hole along the first direction, and a slider is provided on the inner wall of the first guide hole;
