Description

Technical Field

[0002] After cold pressing, the coated lithium battery film rolls are placed on a die-cutting machine for laser die-cutting, facilitating the cutting of the tabs and the identification of defective products. For out-of-specification defective products, the die-cutting machine uses line scan cameras and area scan cameras to identify the electrodes, marking any defective products that exceed the specifications.

[0003] Marking generally requires a marking mechanism. Currently used marking mechanisms all use a counterweighted marking pressure wheel to press the bad product label paper. However, when there are too many bad cathode / anode plates, the current marking mechanism will continuously mark the plates. Due to the counterweight problem of the pressure wheel itself, the pressure wheel will bounce up, resulting in the bad product label paper not sticking tightly, causing the bad products to be rolled into the battery cell, causing quality risks to the battery cell.

[0050] Currently, after cold pressing, coated lithium battery film rolls are placed on a die-cutting machine for laser die-cutting to facilitate the cutting of the tabs and the identification and detection of defective products. For defective products that exceed specifications, the die-cutting machine can use line scan cameras and area scan cameras to identify the electrodes, and those that exceed the specifications need to be marked.

[0051] Marking generally requires a marking mechanism. Currently used marking mechanisms all use a counterweighted marking pressure wheel to press the bad product label paper. However, when there are too many bad cathode / anode plates, the current marking mechanism will continuously mark the plates. Due to the counterweight problem of the pressure wheel itself, the pressure wheel will bounce up, resulting in the bad product label paper not sticking tightly, causing the bad products to be rolled into the battery cell, causing quality risks to the battery cell.

[0052] Based on the above problems, the present application designs a marking machine and a fixing device. By arranging a fixing device on the marking machine and connecting it to the marking pressure wheel, the elastic part in the fixing device is used to realize the clamping function of the pressure wheel, so that the pressure wheel will not bounce up due to its own configuration problems during continuous marking, thereby ensuring that the label paper of the defective electrode can be accurately adhered to the electrode, thereby improving the quality of the battery cell.

[0053] Based on the above ideas, this application first provides a marking machine, such as Figure 1 As shown, the marking machine includes a marking pressure wheel 10 and a fixing device 20, the fixing device 20 is connected to the marking pressure wheel 10, and the fixing device 20 includes an elastic member 210, which can apply a force to the marking pressure wheel toward the supporting surface of the marking machine to fix the marking pressure wheel.

[0054] Among them, the marking machine of the present application refers to a machine device for pressing the label paper of the electrode, and the marking pressure wheel refers to a pressure wheel device for pressing the label paper of the battery electrode; when the marking machine is placed on the ground, the support surface of the marking machine is represented as the ground. Of course, when the marking machine is placed on other placement planes, the placement plane is the support surface of the marking machine.

[0055] The fixing device of the above design, this solution is to set a fixing device for the marking pressure wheel on the marking machine, and apply a force toward the supporting surface of the fixing device to the marking pressure wheel through the elastic part in the fixing device, thereby realizing the clamping function of the pressure wheel, so that the pressure wheel will not bounce up due to its own configuration problems during continuous marking, thereby ensuring that the label paper of the defective electrode can be accurately adhered to the electrode, thereby improving the quality of the battery cell.

[0056] As a possible implementation, Figure 2 As shown, the fixing device designed in this solution may further include a mounting block 220 and a limiting block 230 in addition to the elastic member 210 .

[0057] The mounting block 220 is connected to the marking pressure wheel 10 of the marking machine, and the elastic member 210 is partially arranged on the mounting block 220. Specifically, the first part 2110 of the elastic member 210 is fixedly connected to the mounting block 220, and the second part of the elastic member 210 extends out of the mounting block 220 to form a distributing portion 2120. The limit block 230 contacts the distributing portion 2120 of the elastic member 210. The limit block 230 can be fixedly set on the marking machine so that the position of the limit block 230 is fixed and stationary, thereby applying contact force to the elastic member 210.

[0058] In the fixing device designed above, the limit block 230 applies a force to the elastic member 210 by contacting the extension portion 2120 of the elastic member 210. Based on the force of the limit block 230, the elastic member 210 applies a force to the marking pressure wheel 10 toward the support surface (such as the ground) of the marking machine through its elastic deformation. Figure 2 As shown, the force applied by the limit block 230 to the elastic member 210 is a force toward the support surface of the marking machine (such as the ground), and the force applied by the elastic deformation to the marking pressure wheel 10 can also be a force toward the support surface of the marking machine (such as the ground). It should be noted that the electrode label paper can be set directly below the marking pressure wheel 10. In this case, the force applied by the elastic deformation to the marking pressure wheel 10 is a force toward the electrode label paper.

[0059] The marking machine designed as above, this solution arranges an elastic member 210 on the mounting block 220, and then applies a force to the protruding portion 2120 of the elastic member 210 through the limit block 230, so that the elastic member 210 applies a force to the marking pressure wheel 10 toward the supporting surface of the marking machine, thereby realizing the clamping function of the pressure wheel through the coordinated action of the elastic member 210 and the limit block 230, so that the pressure wheel will not bounce up due to its own configuration problems during continuous marking, thereby ensuring that the label paper of the defective electrode can be accurately adhered to the electrode, thereby improving the quality of the battery cell.

[0060] In an optional implementation of this embodiment, if Figure 3 As shown, a groove 2210 is formed on the mounting block 220 of the present invention, and the first portion 2110 of the elastic member 210 is disposed in the groove 2210 .

[0061] For further information, please refer to Figure 3The groove 2210 designed in this scheme may include an installation groove 22110 and a limiting groove 22120. The first part 2110 of the elastic member 210 includes a first end 21110 and a first branch segment 21120. In this case, the first end 21110 of the elastic member 210 is arranged in the limiting groove 22120, and the first end 21110 of the elastic member 210 is connected to the side wall of the limiting groove 22120, and the first branch segment 21120 of the elastic member 210 is arranged in the installation groove 22110.

[0062] As one possible embodiment, to facilitate replacement of the elastic member 210, the first end portion 21110 of the elastic member 210 of this embodiment can abut against the side wall of the limiting groove 22120, and the first branch section 21120 of the elastic member 210 can be clamped in the mounting groove 22110. As another possible embodiment, to improve the secure fixation of the elastic member 210 to the mounting block 220, the first end portion 21110 of the elastic member 210 of this embodiment can be bonded or welded to the side wall of the limiting groove 22120, and the first branch section 21120 of the elastic member 210 can be bonded or welded in the mounting groove 22110.

[0063] Furthermore, the mounting groove 22110 of the present invention can be a centrally symmetrical closed graphic shape. In this case, the first branch section 21120 of the elastic member is wound around the mounting groove 22110. As a specific embodiment, the centrally symmetrical closed graphic shape can be as follows: Figure 2 and 3 As shown in the circular shape, the first branch section 21120 of the elastic member 210 is wound in the circular mounting groove 22110. Of course, the shape of the mounting groove 22110 can be other forms of centrally symmetrical closed figures besides the circle, for example, square, diamond, etc.

[0064] Furthermore, the elastic member 210 designed in this scheme can be specifically a spring. In this case, the first branch section 21120 of the spring is wound in the mounting groove 22110, and the first end 21110 of the spring is set in the limiting groove 22120, and the second end of the spring extends out of the mounting block 220 to form a distributing portion 2120, and then the spring is compressed by contacting the distributing portion 2120 through the limiting block 230, so that the spring compresses the marking pressure wheel 10 through elastic deformation.

[0065] Furthermore, since different production processes require different production speeds of marking machines, that is, different production process marking machines have different marking speeds of marking rollers, in this case, different pressing forces need to be applied to the marking roller 10 according to different marking speeds to avoid marking roller failure problems caused by the mismatch between the pressing force and the marking speed. For example, when the marking speed is fast, excessive pressing force can be applied to the marking roller 10, which may cause the marking roller 10 to remain in a relatively tight state at high speeds, thereby causing damage to the marking roller 10. In response to the above situation, the elastic member 210 designed in this solution can use springs with different elastic coefficients according to actual conditions. Then, by replacing the pressing springs with different elastic coefficients, different degrees of pressing force can be applied to the marking roller 10, so that the marking roller 10 can select springs with appropriate elastic coefficients according to different marking speeds, thereby matching the pressing force of the marking roller with its marking speed, thereby avoiding the hidden danger of marking roller damage caused by the mismatch between the pressing force and the marking speed. It should be noted here that in order to facilitate the replacement of springs with different elastic coefficients, the elastic member 210 can be detachably arranged on the mounting block 220. For example, as described above, the first end portion 21110 of the elastic member 210 can abut against the side wall of the limiting groove 22120, and the first branch segment 21120 of the elastic member 210 can be wound and then clamped in the mounting groove 22110.

[0066] In addition, the elastic member designed in this solution can be other elastic media with elastic properties in addition to the spring, and can be adaptively adjusted according to the actual application scenario.

[0067] In an optional implementation of this embodiment, as a possible implementation, in order to ensure the firmness and stability of the connection between the fixing device 20 and the marking pressure wheel 10, the mounting block 220 designed in this solution can be fixedly connected to the marking pressure wheel 10, such as by welding, etc.

[0068] As another possible implementation, in order to realize the pressing function of the marking machine for label papers with different lengths of electrodes, thereby improving the applicability of the marking machine, the mounting block 220 designed in this solution can be detachably connected to the marking pressure wheel 10. Specifically, as a possible implementation, Figure 4As shown, a plurality of connection holes 2220 can be provided on the mounting block 220 designed in the present scheme, and different connection holes 2220 are at different distances from the edge of the mounting block 220. Based on this, when the mounting block 220 is fixed by the first fixing member based on different connection holes 2220, the spacing between the mounting block 220 and the marking pressure wheel 10 is different, and then the connection holes 2220 at different positions can be connected by the marking pressure wheel 10 to realize adjustment of the extension length of the marking pressure wheel 10, thereby making it possible to flexibly control the position of the designed marking pressure wheel relative to the electrode, thereby realizing the pressing function of the marking machine for label paper of electrodes of different lengths. In addition, the connection holes 2220 at different positions can make the distance between the marking pressure wheel 10 and the mounting block 220 different, so that the designed fixing device can realize the connection between the mounting block 220 and marking pressure wheels 10 of different sizes through the connection holes 2220 at different positions, so that when the designed marking machine replaces marking pressure wheels 10 of different sizes, marking pressure wheels 10 of different sizes can be applied with force to the support surface of the marking machine by the fixing device, thereby improving the applicability and reliability of the marking machine.

[0069] As another possible implementation, Figure 5 As shown, a strip hole groove 2230 can also be provided on the mounting block 220 designed in the present invention. In this case, the present invention can utilize a second fixing member to fix the marking pressure wheel 10 at different positions of the strip hole groove 2230, thereby adjusting the distance between the mounting block 220 and the marking pressure wheel 10 through different positions of the strip hole groove 2230, thereby realizing adjustment of the extension length of the marking pressure wheel 10, thereby enabling flexible control of the position of the designed marking pressure wheel relative to the electrode, thereby realizing the pressing function of the marking machine for label paper with electrodes of different lengths. In addition, different installation positions in the strip hole groove 2230 can make the distance between the marking pressure wheel 10 and the mounting block 220 different, so that the designed fixing device can realize the connection between the mounting block 220 and marking pressure wheels 10 of different sizes through different installation positions in the strip hole groove 2230, so that when the designed marking machine replaces marking pressure wheels 10 of different sizes, marking pressure wheels 10 of different sizes can be applied with force to the support surface of the marking machine by the fixing device, thereby improving the applicability and reliability of the marking machine.

[0070] In an optional implementation of this embodiment, if Figure 6As shown, the limit block 230 of the present invention may include an adjustment rod 2310 and a stop rod 2320, wherein the first end of the stop rod 2320 is connected to the first end of the adjustment rod 2310, and the stop rod 2320 and the adjustment rod 2310 are perpendicular to each other, and the stop rod 2320 contacts the protruding portion 2120 of the elastic member 210. The limit block 230 may be positioned above the marking pressure wheel 10, so that the stop rod 2320 contacts the protruding portion 2120 of the elastic member 210 and applies a force toward the support surface of the marking machine, so that the elastic member 210 applies a force toward the support surface of the marking machine to the marking pressure wheel 10 through elastic deformation.

[0071] Furthermore, the limit block 230 designed above can adjust the position of the baffle rod 2320 through the adjusting rod 2310 to realize the contact position adjustment of the baffle rod 2320 and the dispensing portion 2120, thereby adjusting the force applied to the elastic member 210, so that the elastic member 210 produces different degrees of elastic deformation, and then adjusts the force applied by the elastic member 210 to the marking pressure wheel 10, so that the clamping force of the marking pressure wheel matches its marking speed, thereby avoiding the hidden danger of damage to the marking pressure wheel caused by the mismatch between the clamping force and the marking speed.

[0072] In an optional implementation manner of this embodiment, as a possible implementation manner, Figure 6 As shown, a strip mounting groove 23110 can be provided on the adjustment rod 2310, and the third fixing member is arranged at different positions of the strip mounting groove 23110, so as to realize the adjustment of different installation heights of the blocking rod 2320, thereby realizing the adjustment of the contact position of the blocking rod 2320 and the expenditure portion 2120, and then adjusting the force applied by the elastic member 210 to the marking pressure wheel 10, so that the clamping force of the marking pressure wheel matches its marking speed, thereby avoiding the hidden danger of damage to the marking pressure wheel caused by the mismatch between the clamping force and the marking speed.

[0073] In an optional implementation manner of this embodiment, as another possible implementation manner, as Figure 7 As shown, the adjustment rod 2310 designed in this scheme can also be a telescopic rod. In this case, the adjustment rod 2310 is telescopic to achieve the adjustment of different installation heights of the blocking rod 2320, thereby achieving the adjustment of the contact position of the blocking rod 2320 and the expenditure part 2120, and then achieving the adjustment of the size of the force acting on the marking pressure wheel 10, so that the clamping force of the marking pressure wheel matches its marking speed, avoiding the hidden danger of damage to the marking pressure wheel caused by the mismatch between the clamping force and the marking speed.

[0074] The present application also provides a fixing device, such as Figure 8As shown, the fixing device is the fixing device 20 in the marking machine described above. The fixing device is used to connect to the marking pressure wheel of the marking machine. The fixing device includes an elastic member, which is configured to apply a force to the marking pressure wheel toward the support surface of the marking machine to fix the marking pressure wheel. In addition, the specific features of the fixing device are consistent with the technical features of the fixing device described in the marking machine above and will not be repeated here.
