Description

Technical Field

[0001] The utility model particularly relates to a rapid die change device for a positioning table of a double-station laminator. Background Art

[0002] Lithium-ion batteries have been widely used in electronic products such as mobile phones and laptop computers due to their advantages of high working voltage, long cycle life, high energy density, small size, light weight, and low pollution, and have become one of the preferred power sources for future power batteries of electric vehicles. Therefore, the requirements for related processes of lithium-ion batteries are becoming more and more stringent. With the wide application of portable electronic products, high-energy-density lithium-ion secondary batteries have emerged as the times require.

[0003] In the prior art, lithium-ion secondary batteries can be formed by the lamination method or by the winding method. Among them, the lamination method is usually to roll the positive and negative electrodes and then punch them into positive and negative small pieces according to specifications, and then stack them with the separator in a "Z" - shaped lamination method to form an electrode laminate for a lithium-ion secondary battery. Before lamination, a pole piece positioning mechanism is usually required to pre-position the pole piece. An existing pole piece positioning mechanism, such as a battery pole piece fixture disclosed in Chinese Patent Publication No. CN201146213Y, discloses a bottom plate, a pole piece clamping block group arranged on the bottom plate for clamping the pole piece in the length direction of the pole piece, and at least one group of pole piece limiting block groups arranged on the bottom plate for limiting the displacement of the pole piece in its width direction; wherein, the clamping block group includes: a first pole piece clamping block and a second pole piece clamping block arranged in the length direction of the bottom plate, and the distance between the first pole piece clamping block and the second pole piece clamping block in the length direction of the bottom plate is adjustable.

[0004] In summary, the existing positioning fixture is only suitable for positioning pole pieces of a single specification size. When it is necessary to switch to pole pieces of different specification sizes, the positioning platform needs to be replaced, and it is not compatible with multiple battery models. For different battery models, different tooling fixtures need to be matched according to the different model sizes of the batteries. Too many tooling fixtures increase the manufacturing cost. When changing the model on the production line, the tooling of the laminating table of the laminating equipment needs to be changed, which is easy to change the tooling incorrectly and lengthens the tooling die change time. Summary of the Utility Model

[0005] Aiming at the defects existing in the above-mentioned prior art, the technical problem to be solved by the utility model is: to provide a rapid die change device for a positioning table of a double-station laminator.

First positioning reference baffles and second positioning reference baffles are respectively arranged on the positioning platform. The length direction of the first positioning reference baffle is perpendicular to the length direction of the second positioning reference baffle. The positioning fixture comprises a first moving member and a second moving member with the same structure. The first moving member moves relatively close to or away from the first positioning reference baffle, and the second moving member moves relatively close to or away from the second positioning reference baffle;

[0007] The first moving member comprises a single-axis linear module and a moving seat arranged on the moving end of the single-axis linear module. Clamping pieces and a driving member capable of driving the clamping pieces to move relatively close to or away from the first positioning reference baffle are respectively arranged on the moving seat. An infrared distance measuring sensor is arranged on one side of the clamping piece corresponding to the first positioning reference baffle, and the infrared distance measuring sensor can be electrically connected to an external digital display module.

[0008] In one embodiment, the clamping piece comprises a limiting part and a supporting part which are connected. The combined outer shape of the limiting part and the supporting part is arranged in an inverted T shape or an L shape, and the supporting part is arranged on the moving seat.

[0009] In one embodiment, a guiding inclined surface is arranged on the upper side end surface of the supporting part.

[0010] In one embodiment, an avoidance groove is formed on the side part of the positioning platform, and the supporting part is movably accommodated in the avoidance groove.

[0011] In one embodiment, the upper side surface of the supporting part is coplanar with the upper side surface of the positioning platform.

[0012] In one embodiment, the driving member adopts a cylinder.

[0013] In one embodiment, the single-axis linear module adopts a ball screw module.

[0014] In summary, the beneficial effects of the present utility model compared with the prior art are as follows:

[0015] Through the combination of the first positioning reference baffle and the second positioning reference baffle, the present utility model realizes the right-angle reference positioning of the pole piece, and then realizes the positioning and clamping of the pole piece by the first moving member and the second moving member respectively moving relatively close to or away from the first positioning reference baffle and the second positioning reference baffle;

[0016] Moreover, it can be effectively adjusted according to the actual size of the pole piece through the single-axis linear module in the first moving member or the second moving member. The user can make intuitive and rapid adjustments based on the real-time feedback of the distance of the infrared ranging sensor, so as to meet the adaptive clamping of different pole piece sizes and achieve the effect of rapid tool change;

[0017] Moreover, through the combined cooperation of the driving cylinder and the single-axis linear module, the driving cylinder can quickly drive the displacement of the clamping piece to position the pole piece, accelerating the positioning efficiency of the pole piece, while the single-axis linear module can play a role in quickly changing the tool during the production of different batch specifications.

[0020] The present invention will be further described below in conjunction with the drawings and detailed embodiments:

[0021] As Figures 1 to 2 shown, preferably, an embodiment of the present invention provides a rapid tool change device for the positioning table of a double-station laminator, including a positioning platform 1 and a positioning fixture arranged on the positioning platform 1. The positioning platform 1 is respectively provided with a first positioning reference baffle 2 and a second positioning reference baffle 3. The length direction of the first positioning reference baffle 2 is perpendicular to the length direction of the second positioning reference baffle 3. The positioning fixture includes a first moving member 4 and a second moving member 5 with the same structure. The first moving member 4 moves relatively close to or away from the first positioning reference baffle 2, and the second moving member 5 moves relatively close to or away from the second positioning reference baffle 3. The first moving member 4 includes a single-axis linear module 41 and a moving seat 42 arranged at the moving end of the single-axis linear module 41. The moving seat 42 is respectively provided with a clamping piece 43 and a driving member 44 that can drive the clamping piece 43 to move relatively close to or away from the first positioning reference baffle 2. One side of the clamping piece 43 is correspondingly arranged facing the first positioning reference baffle 2 with an infrared ranging sensor 45, and the infrared ranging sensor 45 can be electrically connected to an external digital display module.

[0022] Specifically, it is a relatively mature prior art that the infrared ranging sensor sends a signal to an external digital display module so that the digital display module receives and displays in real time the distance between the clamping piece and the positioning reference baffle, and the structural principle thereof will not be elaborated in detail here;

[0023] Through the combination of the first positioning reference baffle and the second positioning reference baffle, the right-angle reference positioning of the pole piece is realized. Then, the first moving member and the second moving member respectively move relatively closer to or away from the first positioning reference baffle and the second positioning reference baffle to realize the positioning and clamping of the pole piece;

[0024] Moreover, the single-axis linear module in the first moving member or the second moving member can effectively adjust according to the actual size of the pole piece. The user can make intuitive and rapid adjustment through the real-time feedback of the distance of the infrared distance sensor, so as to meet the adaptive clamping of different pole piece sizes and achieve the effect of rapid tool change.

[0025] Further, the clip 43 includes a connected limiting portion 61 and a supporting portion 62, and the combined shape of the limiting portion 61 and the supporting portion 62 is set in an inverted T shape or an L shape. The supporting portion 62 is arranged on the moving seat 42.

[0026] Further, a guiding inclined surface 63 is arranged on the upper side end surface of the supporting portion 62. Further, when the supporting portion is driven to displace and abut against the lower part of the pole piece on the positioning platform through the guiding inclined surface, the pole piece can be guided to be flush to avoid clamping damage.

[0027] Further, an avoidance groove 64 is formed on the side part of the positioning platform 1, and the supporting portion 62 is movably accommodated in the avoidance groove 64. The upper side surface of the supporting portion 62 is coplanar with the upper side surface of the positioning platform 1.

[0028] Further, the driving member 44 adopts a cylinder. Specifically, through the combined cooperation of the driving cylinder and the single-axis linear module, the driving cylinder can quickly drive the clip to displace and position the pole piece, accelerating the positioning efficiency of the pole piece, while the single-axis linear module can play a role in quickly changing the tool in the production of different batch specifications.

[0029] Further, the single-axis linear module 41 adopts a ball screw module.
