Description

Technical Field

[0001] This application relates to the field of lithium battery manufacturing equipment, and in particular to a detection device for a coating machine gap valve. Background Technology

[0002] As is well known, coating machines are important production equipment for lithium batteries, and coating pneumatic gap valves are important components of coating machines.

[0003] In related technologies, during the maintenance, installation, and adjustment of pneumatic gap valves for coating, the smoothness of the lever's up-and-down movement relies entirely on experience and feel. Different operators often produce varying degrees of pushing and pulling force. This difference can cause the gap valve lever to experience jerking or become overly sensitive during its up-and-down movement, affecting adjustment accuracy and preventing the valve core from reaching the precise position. Consequently, problems such as uneven coating density, thinning, or dimensional abnormalities may occur during the coating process. Utility Model Content

[0027] Although illustrative embodiments have been demonstrated and described, those skilled in the art should understand that the above embodiments should not be construed as limiting the present application, and that changes, substitutions and modifications can be made to the embodiments without departing from the spirit, principles and scope of the present application.

[0028] In existing technologies, during the maintenance, installation, and adjustment of pneumatic gap valves for coating, the smoothness of the lever's up-and-down movement relies entirely on experience and feel. Different operators often produce varying degrees of pushing and pulling force. This variation can cause the gap valve lever to experience jerking or become overly sensitive during its up-and-down movement, affecting adjustment accuracy and preventing the valve core from reaching the precise position. Consequently, problems such as uneven coating density, thinning, or dimensional abnormalities may occur during the coating process.

[0029] This application proposes a detection device 100 for the gap valve of a coating machine, with reference to... Figure 1 , Figure 1 This is a schematic diagram of the structure of a detection device 100 for a coating machine gap valve in one embodiment of this application. In some embodiments, the gap valve includes a valve body and a pull rod slidably connected to the valve body. The detection device 100 for the coating machine gap valve includes a base 110, a fixed base 120, a movable base 130, and a drive assembly 140. The fixed base 120 is disposed on the base 110 and is used to install the gap valve. The movable base 130 is movably disposed on the base 110 and spaced apart from the fixed base 120. The movable base 130 is used to install a force measuring assembly, and the measuring end of the force measuring assembly is connected to the pull rod of the gap valve. The drive assembly 140 is disposed on the base 110, and the driving part of the drive assembly 140 is connected to the movable base 130 to drive the movable base 130 to reciprocate in a direction away from or close to the fixed base 120.

[0030] In this embodiment, the base 110 is the basic structure of the entire device. Specifically, it can be a plate-shaped or block-shaped metal material, serving to support the fixed base 120, the movable base 130, and the drive assembly 140. Mounting holes for the fixed base 120, the movable base 130, and the drive assembly 140 are pre-drilled on the base 110 to facilitate their installation. The fixed base 120 is the fixed part installed on the base 110. Specifically, it can be a block structure or a cubic structure formed by multiple plates. Its upper surface is used to install the gap valve, serving to fix the valve body of the gap valve, so that the pull rod can be pushed and pulled relative to the valve body, thereby measuring the smoothness of the pull rod. The movable base 130 is a movable part movably mounted on the base 110. Movement between the movable base 130 and the base 110 can be achieved through the cooperation of a slide rail and a slider 144, or through a slide groove and rollers, or through a combination of a guide column and a sliding bearing. No further limitation is made here, as long as the movable base 130 can drive the force-measuring component on it to move linearly back and forth relative to the base 110 towards or away from the fixed base 120. Alternatively, in another embodiment, the force-measuring component is mounted on the fixed base 120, and the gap valve is mounted on the movable base 130, which can also achieve the effect of measuring the pushing and pulling forces when the pull rod moves. The drive component 140 is the mechanism that drives the movable base 130 to move. Specifically, it can be a linear motor, a lead screw 141 structure, or a ball screw structure, as long as it can drive the movable base 130 to move linearly back and forth towards or away from the fixed base 120. No further limitation is made here. The measuring end of the force measuring component and the pull rod can be connected by a probe nut 142 with internal threads at both ends, so that the force measuring component can drive the pull rod of the gap valve to move together.

[0031] It is understood that, in a preferred embodiment, by adjusting the height of the fixed base 120 and the height of the movable base 130, the pull rod of the gap valve installed on the fixed base 120 is coaxially set with the measuring end of the force measuring component installed on the movable base 130, ensuring that the measuring end and the pull rod are at the same height and the same horizontal position, preventing the pull rod from deflecting during movement and interfering with the valve body, thus affecting the accuracy of the measurement results.

[0032] The coating machine gap valve testing device 100 in this application includes a base 110, a fixed base 120 disposed on the base 110, a movable base 130 movably disposed on the base 110, and a drive assembly 140 for driving the movable base 130 away from or towards the fixed base 120. During testing, the gap valve is installed on the fixed base 120 with the valve's pull rod facing the movable base 130. Simultaneously, a force measuring assembly is placed on the movable base 130 with its measuring end facing the fixed base 120. The measuring end of the force measuring assembly is connected to the gap valve's pull rod. The drive assembly 140 is controlled to drive the movable base 130 to reciprocate in the direction of approaching or moving away from the fixed base 120, thereby measuring the tension and thrust values ​​when the pull rod moves smoothly. The verified optimal empirical values ​​are solidified and quantified for control, ensuring that the smoothness of the gap valve pull rod remains consistent after maintenance, improving the adjustment accuracy of the gap valve, enhancing coating quality, and ultimately improving cell quality.

[0033] In some embodiments, the detection device 100 for the gap valve of the coating machine further includes a positioning base plate 150 and a fixing member 160. The positioning base plate 150 is disposed on the upper surface of the fixed base 120, and the two ends of the fixing member 160 are detachably connected to the opposite sides of the positioning base plate 150 to surround and fix the gap valve to the positioning base plate 150.

[0034] In this embodiment, the positioning base plate 150 is a component that directly supports the gap valve and is set on the upper surface of the fixed base 120. Specifically, it adopts a metal plate structure, such as an aluminum alloy plate. The positioning base plate 150 and the fixed base 120 can be connected by screws or welding. The fixing member 160 is a part that mounts the gap valve onto the positioning base plate 150. Specifically, it is a U-shaped plate structure with lugs at both ends and connecting holes on the lugs for threading screws or other connecting parts. The advantage of the U-shaped structure of the fixing member 160 is that it can fix the gap valve in both the vertical and horizontal directions, preventing the gap valve from tilting in the vertical and horizontal directions during measurement, thus affecting the accuracy of the measurement results. In a preferred embodiment, one side of the connecting hole on the lug of the fixing member 160 is open, allowing the connecting part to remain connected to the positioning base plate 150 without needing to be completely unscrewed, thus improving measurement efficiency.

[0035] In some embodiments, the positioning base plate 150 includes a first positioning block 151, which is disposed on the positioning base plate 150 along the width direction of the positioning base plate 150.

[0036] In this embodiment, the first positioning block 151 is a limiting structure set on the positioning base plate 150. It is set along the width direction of the positioning base plate 150. When one end of the gap valve abuts against the first positioning block 151, it indicates that the gap valve has been installed in the length direction, thus achieving the effect of positioning and limiting the gap valve in the length direction.

[0037] In some embodiments, the positioning base plate 150 further includes a second positioning block 152, which is disposed on the positioning base plate 150 along the length direction of the positioning base plate 150.

[0038] In this embodiment, the second positioning block 152 is a limiting structure set on the positioning base plate 150. It is set along the length direction of the positioning base plate 150. When one side of the gap valve abuts against the second positioning block 152, it indicates that the gap valve has been installed in the width direction, thus achieving the effect of positioning and limiting the gap valve in the width direction. With the cooperation of the first positioning block 151 and the second positioning block 152, when the tester installs the gap valve onto the positioning base plate 150, he only needs to abut the end face of the gap valve against the first positioning block 151 and the side of the gap valve against the second limiting block to complete the installation of the gap valve, achieving the effect of rapid positioning and limiting, and improving the measurement efficiency of this device.

[0039] In some embodiments, there are two second positioning blocks 152, and the two second positioning blocks 152 are spaced apart along the length direction of the positioning base plate 150.

[0040] In this embodiment, since the length of the gap valve is generally greater than the width of the gap valve, two second positioning blocks 152 are set at intervals along the length direction of the positioning base plate 150 to better position and limit one side of the gap valve, thereby achieving the effect of rapid positioning and limiting and improving the measurement efficiency of the device.

[0041] In some embodiments, the detection device 100 for the gap valve of the coating machine further includes a fastener 170. The fixing member 160 has a through hole on the side opposite to the positioning base plate 150. The fastener 170 is rotatably connected to the through hole. One end of the fastener 170 passes through the through hole and abuts against the gap valve. The other end of the fastener 170 is engaged at the edge of the through hole.

[0042] In this embodiment, the fastener 170 is a component that passes through the fixing member 160 and abuts against the gap valve. Specifically, it can be a screw or a wing screw, which facilitates rotational connection with the through hole on the fixing member 160. By rotating, the length of one end of the fastener 170 exposed in the through hole is increased, thereby locking the gap valve and preventing the gap valve from moving during the measurement process, which would make the measurement results inaccurate.

[0043] In some embodiments, a bolt cup head is protruding from the surface of the gap valve facing the positioning base plate 150; a countersunk hole 153 is provided on the positioning base plate 150 for accommodating the bolt cup head.

[0044] In this embodiment, a fixing plate is provided on the outer periphery of the valve body of the gap valve. The fixing plate is connected by bolts, and the bolt cup head protrudes out of the plane of the gap valve. Correspondingly, a countersunk hole 153 corresponding to the bolt cup head is formed on the positioning base plate 150 to accommodate the bolt cup head, so that the surface of the gap valve and the positioning base plate 150 fit together smoothly and efficiently, improving the accuracy of the measurement. Furthermore, the cooperation between the bolt cup head and the countersunk hole 153 can also play a certain positioning and limiting role, further improving the measurement efficiency and the stability of the measurement results.

[0045] In some embodiments, the drive assembly 140 is a lead screw 141 structure, which includes a lead screw 141 and a nut 142. The nut 142 is disposed on the movable base 130. One end of the lead screw 141 passes through the movable base 130 and is rotatably connected to the fixed base 120. The middle part of the lead screw 141 is threadedly connected to the nut 142. The other end of the lead screw 141 is driven so that the nut 142 drives the movable base 130 to reciprocate relative to the lead screw 141.

[0046] In this embodiment, the drive component 140 is a lead screw 141 structure. The lead screw 141 structure has stable operation, small jump, and high accuracy, thus improving the accuracy of the measurement. One end of the lead screw 141 passes through the movable base 130 and is rotatably connected to the fixed base 120. The nut 142 is set on the movable base 130, and the middle part of the lead screw 141 is rotatably connected to the nut 142. When the other end of the lead screw 141 is driven, the lead screw 141 and the nut 142 rotate relative to each other, causing the nut 142 to move along the length direction of the lead screw 141. This, in turn, drives the movable base 130 to move along the length direction of the lead screw 141, that is, to move away from or towards the fixed base 120, ultimately achieving the purpose of pushing and pulling the rod to measure the force when the rod moves.

[0047] In some embodiments, the drive assembly 140 further includes a guide rail 143 and a slider 144. The guide rail 143 is disposed on the base 110, one surface of the slider 144 is slidably connected to the guide rail 143, and the other surface of the slider 144 is connected to the movable base 130.

[0048] In this embodiment, in order to reduce the friction between the movable base 130 and the base 110, a guide rail 143 and slider 144 structure is provided between them. The guide rail 143 is provided on the base 110 and is provided along the interval direction from the movable base 130 to the fixed base 120. One end of the slider 144 is slidably connected to the guide rail 143, and the other end is connected to the bottom surface of the movable base 130. The slider 144 slides relative to the guide rail 143, so that the movable base 130 can slide back and forth along the extension direction of the guide rail 143, and finally achieve the effect of the movable base 130 moving away from or closer to the fixed base 120. It is understood that, in a preferred embodiment, there are two guide rails 143 and two sliders 144. The two guide rails 143 are spaced apart and parallel to each other on the base 110. One surface of the two sliders 144 is connected to the two guide rails 143 respectively, and the other surface of the two sliders 144 is connected to the bottom surface of the movable base 130. The cooperation of the two guide rails 143 and the two sliders 144 can stabilize the movement of the movable base 130 and prevent the movable base 130 from jumping or other problems that may affect the measurement results.

[0049] In some embodiments, the drive assembly 140 further includes a vertical plate 145 and an adjusting handwheel 146. The vertical plate 145 is disposed on the base 110 and located on the side of the movable base 130 opposite to the fixed base 120. The vertical plate 145 has a through hole, and the other end of the lead screw 141 passes through the through hole and is connected to the adjusting handwheel 146.

[0050] In this embodiment, the upright plate 145 is mounted on the base 110, and a through hole is provided on it for the other end of the lead screw 141. This serves to stabilize the lead screw 141 and prevent it from tilting under its own weight, thus affecting the movement of the movable base 130. The other end of the lead screw 141 passes through the through hole and is connected to the adjusting handwheel 146. The tester can drive the other end of the lead screw 141 by shaking the adjusting handwheel 146, which saves effort and improves the efficiency of the test. It is understood that, in a preferred embodiment, a rotary bearing is provided between the through hole and the outer peripheral wall of the lead screw 141 to make the rotation between the two smoother and prevent the lead screw 141 or the through hole of the upright plate 145 from being worn.

[0051] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
