Description

Technical Field

[0001] The invention relates to the technical field of DCR testing equipment, in particular to a backstop mechanism for feeding a DCR tray. Background Art

[0002] After the lithium battery is produced, it needs to undergo a series of tests, including the DCR test (DC resistance test). During the test, the lithium battery needs to be loaded on a DCR tray and transported to the DCR test equipment for testing.

[0003] During the feeding process, the DCR pallet will rebound when it contacts the limit buffer block due to inertia, so that the DCR pallet cannot contact the limit buffer block and cannot be effectively positioned. To solve this problem, the feeding roller plane is tilted to use the gravity force for feeding, but this method is only effective when the feeding speed is low and the inertia is small. When the feeding speed is high and the inertia is large, the rebound phenomenon will still occur.

[0004] Therefore, how to provide a back-stop mechanism for DCR tray feeding to improve the reliability of DCR tray feeding has become a technical problem to be solved urgently. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a back-stop mechanism for DCR tray feeding, so as to improve the reliability of DCR tray feeding.

[0006] The present invention is implemented as follows: a backstop mechanism for DCR tray feeding, comprising:

[0007] A base having a rotation groove, and a first rotation hole is formed through the rotation groove;

[0008] A stop buckle, the side wall of the rear end of which is penetrated by a second rotation hole, and the front end of which is extended forward side by side by two hooks; the side wall of each hook is penetrated by a mounting groove;

[0009] A buckle pin shaft passes through the first rotating hole and the second rotating hole;

[0010] A back-stop buckle spring, the bottom end of which is connected to the top end of the rotating groove, and the top end of which is connected to the bottom end of the back-stop buckle;

[0011] a pressing plate detachably connected to the top of the base;

[0012] Two release components are respectively arranged in one of the installation grooves.

[0013] Furthermore, the release assembly comprises:

[0014] A fixing plate, arranged on the outer side of the mounting groove;

[0015] A release spring, arranged on the fixing plate and located in the mounting groove;

[0016] A release arm is arranged in the installation slot and abuts against the release spring;

[0017] A tripping rotating arm pin passes through the hook and the tripping rotating arm from bottom to top;

[0018] a trip roller pin;

[0019] A release roller is rotatably connected to the movable end of the release rotating arm through the release roller pin.

[0020] Furthermore, it also includes:

[0021] A plurality of shaft elastic retaining rings are sleeved on the buckle pin shaft, the unbuckling rotating arm pin shaft and the unbuckling roller pin shaft.

[0022] Furthermore, it also includes:

[0023] A hexagonal nut, disposed on the pressing plate;

[0024] A bolt is rotatably connected to the hexagonal nut and passes through the pressure plate to abut against the backstop buckle.

[0035] The embodiment of the present invention solves the technical problem in the prior art that the DCR pallet may rebound due to inertia during the feeding process by providing a stop mechanism for feeding the DCR pallet, thereby achieving the technical effect of greatly improving the reliability of feeding the DCR pallet.

[0036] The technical solution in the embodiment of the present invention is to solve the above-mentioned problem, and the overall idea is as follows: a back-stop buckle is provided to be rotatably connected with a rotating groove by a buckle pin, a back-stop buckle spring is provided between the back-stop buckle and the rotating groove, and the back-stop buckle is lifted up by the back-stop buckle spring to clamp the card to prevent the DCR pallet from rebounding, so as to improve the reliability of DCR pallet feeding.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Please refer to Figures 1 to 4 As shown, a preferred embodiment of a backstop mechanism 100 for DCR tray feeding of the present invention comprises:

[0039] A base 1 is provided with a rotation groove 11, and a first rotation hole (not shown) is provided through the rotation groove 11; the base 1 is used to carry the backstop mechanism 100;

[0040] A back-stop buckle 2, a second rotation hole (not shown) is penetrated through the side wall of the rear end, and two hooks 21 are extended forward side by side at the front end; a mounting groove 211 is penetrated through the side wall of each hook 21; the back-stop buckle 2 is used to hook the card (convex shape) of the DCR tray (not shown) to prevent the DCR tray from rebounding;

[0041] A buckle pin shaft 3 passes through the first rotation hole and the second rotation hole and is used for limiting the rotation of the stop buckle 2;

[0042] A backstop buckle spring 4, the bottom end of which is connected to the top end of the rotating groove 11, and the top end of which is connected to the bottom end of the backstop buckle 2, for providing power for the rebound of the backstop buckle 2;

[0043] a pressing plate 5 detachably connected to the top of the base 1;

[0044] Two unlocking components 6 are respectively disposed in one of the mounting slots 211 and are used to unlock the DCR tray.

[0045] The release assembly 6 comprises:

[0046] A fixing plate 61, disposed outside the mounting groove 211;

[0047] A trip spring 62, provided on the fixing plate 61 and located in the mounting slot 211, for providing power for the rebound of the trip arm 62;

[0048] A tripping arm 63 is disposed in the mounting groove 211 and abuts against the tripping spring 62;

[0049] A release arm pin 64 passes through the hook 21 and the release arm 63 from bottom to top;

[0050] a trip roller pin 65;

[0051] A release roller 66 is rotatably connected to the movable end of the release arm 63 via the release roller pin 65 .

[0052] Also includes:

[0053] A plurality of shaft elastic retaining rings 7 are sleeved on the buckle pin shaft 3 , the unbuckling rotating arm pin shaft 64 and the unbuckling roller pin shaft 65 .

[0054] Also includes:

[0055] A hexagonal nut 8, provided on the pressing plate 5;

[0056] A bolt 9 is rotatably connected to the hexagonal nut 8 and passes through the pressure plate 5 to abut against the anti-retraction buckle 2, so as to adjust the rotatable angle of the anti-retraction buckle 2, that is, to adjust the gap between the anti-retraction buckle 2 and the clamping part of the DCR tray.

[0057] Working principle of the present invention:

[0058] DCR pallet feeding stop retreat: When the card of the DCR pallet passes through the stop retreat buckle 2, the stop retreat buckle spring 4 acts on the stop retreat buckle 2, so that the stop retreat buckle 2 clamps the card, and at the same time the card presses the release roller 66, so that the release arm 63 retracts into the installation groove 211, thereby realizing the stop retreat of the DCR pallet after it is in place.

[0059] DCR pallet unbuckling: during the DCR test, the DCR pallet rises, the card part detaches from the unbuckling roller 66, and the unbuckling arm 63 resets the unbuckling roller 66; after the DCR test, the DCR pallet descends, the card part descends and contacts the unbuckling roller 66 from top to bottom, and the unbuckling roller 66 is subjected to the force from top to bottom and cannot drive the unbuckling arm 63 to rotate and retract, thereby causing the anti-retraction buckle 2 to rotate downward around the buckle pin 3, so that the anti-retraction buckle 2 cannot clamp the inner wall of the card part, so the DCR pallet can withdraw along the feeding direction to achieve automatic unbuckling.

[0060] In summary, the advantages of the present invention are:

[0061] 1. A backstop buckle is provided to be rotatably connected with the rotating groove by using the buckle pin shaft, and a backstop buckle spring is provided between the backstop buckle and the rotating groove. When the card of the DCR pallet passes through the backstop buckle, the card first presses down the backstop buckle to compress the backstop buckle spring. When the backstop buckle slides into the card, it is lifted up by the backstop buckle spring, that is, the card is buckled to prevent the DCR pallet from rebounding, thereby greatly improving the reliability of DCR pallet feeding.

[0062] 2. By setting a hexagonal nut on the pressure plate, setting a bolt to be rotatably connected with the hexagonal nut, and passing through the pressure plate to abut against the anti-retraction buckle, the gap between the anti-retraction buckle and the clamp of the DCR tray can be adjusted by rotating the bolt, that is, the tightness is adjusted, thereby greatly improving the compatibility of the anti-retraction mechanism.
