Description
Technical Field
[0001] The utility model relates to the technical field of battery assembly equipment, in particular to a steel bead punching tooling. Background Art
[0002] With the continuous development of the production technology of square aluminum shell batteries, there are usually two sealing methods for the liquid injection holes of square aluminum shell batteries in the current market. One is: plugging a sealing glue nail and welding a sealing aluminum nail, and the other is: punching steel beads and dispensing glue. For the two different sealing methods, each has its own advantages and disadvantages. Since it is impossible to truly detect whether the sealing aluminum nail is welded well after the sealing glue nail is inserted, the industry is currently exploring the use of the method of punching steel beads and dispensing glue.
[0003] Since steel beads are not easy to pick up during the assembly process and are mostly inserted by workers knocking. Therefore, there will be situations where the surrounding of the liquid injection hole is scratched or the insertion depth of the steel beads is different. Content of the Utility Model
[0004] The purpose of the utility model is to provide a steel bead punching tooling to solve the technical problem of different depths of manually punching steel beads at present.
[0005] The utility model provides a steel bead punching tooling, which includes a main tooling pipe and an auxiliary tooling pipe. The auxiliary tooling pipe is connected and communicated with the main tooling pipe, and the main tooling pipe and the auxiliary tooling pipe are arranged at an acute angle;
[0006] A lead screw is screwed in the main tooling pipe, and a ejector rod is arranged at the lower end of the lead screw; the auxiliary tooling pipe is used to fill steel beads into the main tooling pipe, and by rotating the lead screw, the ejector rod is used to drive the steel beads into the liquid injection hole of the battery cover plate.
[0007] In an optional embodiment, a buffer pipe is arranged at the lower end of the main tooling pipe, and the buffer pipe is screwed at the lower end of the main tooling pipe.

[0014] In an alternative embodiment, the guide plate has a guide surface for guiding the steel ball to the guide perforation.
[0015] In an alternative embodiment, the buffer pipe is made of rubber.
[0016] The main tooling pipe of the steel ball injection tooling provided by the present utility model corresponds to the liquid injection hole of the battery cover plate. The steel ball enters the main tooling pipe from the auxiliary tooling pipe and moves above the liquid injection hole. By rotating the lead screw, the ejector rod moves downward to inject the steel ball into the liquid injection hole; by controlling the number of rotation turns of the lead screw, the depth of the steel ball injected into the liquid injection hole is the same; the success rate and quality of assembling the steel ball to the battery cover plate are improved, and the assembly efficiency is increased; ensuring that the sealing effect meets the requirements and improving the consistency of the product.

[0031] Next, the technical solutions of the present application will be clearly and completely described with reference to the drawings.
[0032] Refer to Figures 1 - 8, the present utility model provides a steel ball punching tooling, which includes a main tooling pipe 500 and an auxiliary tooling pipe 200. The auxiliary tooling pipe 200 is connected and communicated with the main tooling pipe 500, and the main tooling pipe 500 and the auxiliary tooling pipe 200 are arranged at an acute angle;
[0033] A lead screw 700 is screwed in the main tooling pipe 500, and a ejector rod 800 is arranged at the lower end of the lead screw 700; the auxiliary tooling pipe 200 is used to fill steel balls into the main tooling pipe 500, and by rotating the lead screw 700, the ejector rod 800 is used to drive the steel balls into the liquid injection hole 110 of the battery cover plate 900.
[0034] In some embodiments, the main tooling pipe 500 of the steel ball punching tooling is vertically placed on the battery cover plate 900, and the auxiliary tooling pipe 200 and the main tooling pipe 500 are arranged at an acute angle; after the steel balls enter the auxiliary tooling pipe 200, the steel balls enter the main tooling pipe 500 along the auxiliary tooling pipe 200 and move downward along the main tooling pipe 500 into the liquid injection hole 110; by rotating the lead screw 700, the lead screw 700 moves downward, and when the lead screw 700 rotates a fixed number of turns, the lead screw 700 descends a fixed distance; that is, the ejector rod 800 drives the steel balls into the liquid injection hole 110 to the same depth; ensuring that the sealing effect meets the requirements and improving the consistency of the product.
[0035] Refer to Figure 7 , in an alternative embodiment, a buffer pipe 600 is provided at the lower end of the main tooling pipe 500, and the buffer pipe 600 is screwed to the lower end of the main tooling pipe 500.
[0036] In some embodiments, the buffer pipe 600 is made of rubber; the tooling main body abuts against the battery cover plate 900 through the buffer pipe 600, that is, the tooling main body does not directly contact the battery cover plate 900, which can avoid scratching the periphery of the liquid injection hole 110 of the battery cover plate 900 during the process of driving the steel balls into the liquid injection hole 110.
[0037] Refer to Figure 4 , in an alternative embodiment, the lead screw 700 includes an upper end portion 701, a threaded portion 702 and a lower end portion 703 arranged in sequence from top to bottom; an installation hole is provided in the lower end portion 703, and the upper end of the ejector rod 800 is screwed into the installation hole.
[0038] In some embodiments, the lower end portion 703 of the lead screw 700 has a mounting hole, and the ejector rod 800 is screwed onto the lower end portion 703 of the lead screw 700; that is, the ejector rod 800 is detachably connected to the lower end portion 703 of the lead screw 700. According to the different specifications of the liquid injection holes 110 of the battery cover plate 900, steel balls of different specifications need to be correspondingly installed, and each specification of steel ball corresponds to an ejector rod 800. By replacing different ejector rods 800, the ejector rod 800 can be matched with steel balls of different specifications, so that the ejector rod 800 can accurately introduce the steel balls into the liquid injection holes 110.
[0039] Referring to Figure 6 , in an alternative embodiment, an upper mounting plate 300 is provided at the upper end of the tooling main pipe 500, and a driving plate 400 is provided on the upper mounting plate 300; a threaded hole 401 is provided on the driving plate 400, and the lead screw 700 is screwed into the threaded hole 401.
[0040] To facilitate the assembly of the lead screw 700 into the tooling main pipe 500, no thread is provided in the tooling main pipe 500. An upper mounting plate 300 is provided on the tooling main pipe 500, the driving plate 400 is fixedly connected to the upper mounting plate 300, a threaded hole 401 is provided on the driving plate 400, and the lead screw 700 is screwed into the threaded hole 401. When the ejector rod 800 needs to be replaced, the bolts for fixing the upper mounting plate 300 and the driving plate 400 are removed, and at this time, the driving plate 400 and the lead screw 700 can be taken out of the tooling main pipe 500 together;
[0041] This facilitates the replacement of the ejector rod 800 on the lead screw 700. After the ejector rod 800 is replaced with the corresponding specification, the lead screw 700 is inserted into the tooling main pipe 500, and then the upper mounting plate 300 and the driving plate 400 are fixed together with bolts, so that the driving plate 400 will not move relative to the upper mounting plate 300.
[0042] In an alternative embodiment, the cross-section of the upper end portion 701 is rectangular.
[0043] In some embodiments, the upper end portion 701 of the lead screw 700 is generally rectangular. The driving device is connected to the upper end portion 701, so as to realize the rotation of the lead screw 700 by using the driving device, and then the lifting of the lead screw 700 relative to the tooling main pipe 500, so that the ejector rod 800 can move towards the steel ball and drive the steel ball into the liquid injection hole 110; accurately control the lifting range of the lead screw 700 to make the lifting distance of the ejector rod 800 fixed, so as to ensure that the depth of the steel ball driven into the liquid injection hole 110 is fixed, and further ensure that the sealing effect meets the requirements and improve the product consistency.
[0044] The upper end portion 701 can also be of other shapes, which is convenient for the lead screw 700 to be connected to the driving device through the upper end portion 701, and the driving device is used to rotate the lead screw 700.
[0045] In an alternative embodiment, the upper mounting plate 300 and the driving plate 400 are fixedly connected by bolts.
[0046] In an alternative embodiment, the ejector rod 800 is concentric with the main tooling pipe 500, and the distance between the outer wall of the ejector rod 800 and the inner wall of the main tooling pipe 500 is greater than the diameter of the steel ball.
[0047] Refer to Figure 7 , in an alternative embodiment, a guide plate is provided at the lower end of the buffer tube 600, and a guide through hole 100 is provided on the guide plate.
[0048] In an alternative embodiment, the guide plate has a guide surface 601 for guiding the steel ball to the guide through hole 100.
[0049] In some embodiments, the ejector rod 800 is concentric with the main tooling pipe 500, that is, the distance between the outer wall of the ejector rod 800 and the inner wall of the main tooling pipe 500 is fixed; when the ejector rod 800 rotates, the distance between the outer wall of the ejector rod 800 and the inner wall of the main tooling pipe 500 will not change; that is, it will not affect the steel ball entering the main tooling pipe 500 from the auxiliary tooling pipe 200 and moving along the guide surface 601 to above the liquid injection hole 110.
[0050] Then, by rotating the lead screw 700, the ejector rod 800 moves towards the steel ball and drives the steel ball into the liquid injection hole 110, and the number of rotation turns of the lead screw 700 is controlled to accurately control the depth of the steel ball driven into the liquid injection hole 110.
[0051] In an alternative embodiment, the buffer tube 600 is made of rubber.
[0052] The rubber buffer tube 600 abuts against the battery cover plate 900. In this way, during the process of assembling the steel ball, the rubber material will not cause scratches on the battery cover plate 900; a guide plate provided in the buffer tube 600 has a guide surface 601. After the steel ball falls onto the guide surface 601, it enters the guide through hole 100 under the guiding action of the guide surface 601. The guide through hole 100 corresponds to the liquid injection hole 110, that is, the steel ball moves above the liquid injection hole 110, and the ejector rod 800 drives the steel ball into the liquid injection hole 110.
[0053] The tooling supervisor 500 of the steel ball punching tooling provided by the present utility model corresponds to the liquid injection hole 110 of the battery cover plate 900. The steel ball enters the tooling main pipe 500 from the tooling auxiliary pipe 200 and moves above the liquid injection hole 110. By rotating the lead screw 700, the ejector rod 800 moves downward to punch the steel ball into the liquid injection hole 110. By controlling the number of rotation turns of the lead screw 700, the depth of the steel ball punched into the liquid injection hole 110 is the same, which improves the success rate and quality of the steel ball assembled to the battery cover plate 900 and improves the assembly efficiency.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model.
