Description

Technical Field

[0001] This utility model relates to the technical field of chemical forming tank cleaning devices, and in particular to a clamping device for picking up broken foil in a chemical forming tank. Background Technology

[0002] In the production process of aluminum electrolytic capacitors, aluminum foil needs to be etched and oxidized in a formation tank. During this process, foil fragments may fall off and settle at the bottom of the tank. If not cleaned in time, this can lead to short circuits or contamination of the electrolyte. However, the connecting arm length of traditional clamping devices is fixed and only applicable to formation tanks of a specific depth. If the depth of the tank varies (e.g., from 0.5m to 3m), clamping devices of different lengths need to be replaced, resulting in high costs and cumbersome operation. Summary of the Invention

[0003] In view of this, it is necessary to provide a clamping device for shredded foil in a forming tank, which is compatible with forming tanks of different depths, thereby reducing production costs and simplifying the clamping operation.

[0004] This utility model provides a clamping device for retrieving broken foil from a forming tank, comprising a telescopic sleeve, a telescopic connecting rod, an upper clamp, and a lower clamp. A first through groove is formed on the top side wall of the telescopic sleeve, and a second through groove is formed on the bottom side wall. The telescopic connecting rod passes through the telescopic sleeve.

The other arm of the upper clamp is fixedly connected to one side of the first through groove. The lower clamp is located at the bottom of the telescopic sleeve, with one arm of the lower clamp passing through the second through groove and connected to the other end of the telescopic connecting rod. Next, the other arm of the lower gripper is fixedly connected to one side of the second through groove. The distance between the two arms of the upper gripper is controlled by rotating one of the arms of the upper gripper, and the one arm of the upper gripper drives the telescopic connecting rod to rotate, so that the telescopic connecting rod drives the one arm of the lower gripper to rotate, thereby controlling the opening and closing of the two arms of the lower gripper, so that the lower gripper can grip the foil fragments. The distance between the upper gripper and the lower gripper is adjusted by controlling the extension or shortening and locking of the telescopic sleeve. At the same time, the upper gripper and the lower gripper cooperate to pull the telescopic connecting rod to extend or shorten, so as to adapt to the formation groove of different depths.

One end of the second telescopic spring is fixedly connected to the third gripping arm, and the other end of the second telescopic spring is fixedly connected to the fourth gripping arm, so that the second telescopic spring forms an arc corresponding to the outer wall of the first sleeve. When the second telescopic spring is not subjected to external force, it pulls the third gripping arm to rotate away from the fourth gripping arm in the second through groove under the guidance of the outer wall of the first sleeve.

[0011] Preferably, the bottom of the third clamping arm and the fourth clamping arm are provided with a brush plate, and multiple copper wires are evenly fixed on the brush plate to form a steel brush.

[0012] Preferably, the telescopic connecting rod includes a first sleeve, a second sleeve, a third sleeve, a first connecting post, and a second connecting post. The length of the first sleeve is adapted to the length of the first sleeve, the length of the second sleeve is adapted to the length of the second sleeve, and the length of the third sleeve is adapted to the length of the third sleeve.

The first sleeve is inserted into the first locking sleeve, and the first locking ring is fastened to the elastic clamping flaps of the first locking sleeve to fix the extension length of the first sleeve inside the second sleeve.

[0014] As can be seen from the above technical solution, the present invention provides a clamping device for crushed foil in a forming tank, comprising a telescopic sleeve, a telescopic connecting rod, an upper clamp, and a lower clamp. A first through groove is formed on the top side wall of the telescopic sleeve, and a second through groove is formed on the bottom side wall of the telescopic sleeve. The telescopic connecting rod passes through the telescopic sleeve. The upper clamp is located at the top of the telescopic sleeve. One arm of the upper clamp passes through the first through groove and is connected to one end of the telescopic connecting rod. The other arm of the upper clamp is fixedly connected to one side of the first through groove. The lower clamp is located at the bottom of the telescopic sleeve. One arm of the lower clamp passes through the second through groove and is connected to the other end of the telescopic connecting rod. The other arm of the lower clamp is fixedly connected to the second through groove. On one side, when gripping broken foil, the operator can control the distance between the two arms of the upper jaw by rotating one of the gripping arms. This, in turn, causes the telescopic connecting rod to rotate, which in turn rotates one of the gripping arms of the lower jaw to control the opening and closing of the two arms, allowing the lower jaw to grip the broken foil. When facing formation tanks of different depths, the operator can adjust the distance between the upper and lower jaws by controlling the extension or retraction and locking of the telescopic sleeve. Simultaneously, the upper and lower jaws work together to pull the telescopic connecting rod to extend or retract, thus accommodating formation tanks of different depths, thereby reducing production costs and simplifying the gripping operation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please refer to Figures 1 to 5This utility model provides a clamping device 10 for handling broken foil in a forming tank, comprising a telescopic sleeve 110, a telescopic connecting rod 120, an upper clamp 130, and a lower clamp 140. A first through groove 111 is formed on the top side wall of the telescopic sleeve 110, and a second through groove 112 is formed on the bottom side wall of the telescopic sleeve 110. The telescopic connecting rod 120 passes through the telescopic sleeve 110. The upper clamp 130 is located at the top of the telescopic sleeve 110. One arm of the upper clamp 130 passes through the first through groove 111 and is connected to one end of the telescopic connecting rod 120. The other arm of the upper clamp 130 is fixedly connected to one side of the first through groove 111. The lower clamp 140 is located at the bottom of the telescopic sleeve 110. One arm of the lower clamp 140 passes through the second through groove 112 and is connected to the other end of the telescopic connecting rod 120. The other arm of the lower clamp 140... Fixedly connected to one side of the second through slot 112, when clamping broken foil, the operator can control the distance between the two arms of the upper jaw 130 by rotating one of the clamping arms of the upper jaw 130. The one clamping arm of the upper jaw 130 drives the telescopic connecting rod 120 to rotate, so that the telescopic connecting rod 120 drives one of the clamping arms of the lower jaw 140 to rotate, thereby controlling the opening and closing of the two clamping arms of the lower jaw 140, so that the lower jaw 140 can clamp the broken foil. When facing formation tanks of different depths, the operator can adjust the distance between the upper jaw 130 and the lower jaw 140 by controlling the extension or shortening and locking of the telescopic sleeve 110. At the same time, the upper jaw 130 and the lower jaw 140 cooperate to pull the telescopic connecting rod 120 to extend or shorten, thus accommodating formation tanks of different depths, thereby reducing production costs and simplifying the clamping operation.

[0025] Furthermore, to accommodate formation grooves of varying depths, the telescopic sleeve 110 includes a first sleeve 113, a second sleeve 114, a third sleeve 115, a first locking member 116, and a second locking member 117. The first sleeve 113 is fitted inside the second sleeve 114, and the second sleeve 114 is fitted inside the third sleeve 115. The first locking member 116 is fixedly disposed at the bottom end of the second sleeve 114, and the second locking member 117 is fixedly disposed at the bottom end of the third sleeve 115. A first through groove 111 is formed at the top end of the third sleeve 115, and a second through groove 112 is formed at the bottom end of the first sleeve 113. The first locking member 116 clamps the first sleeve 113 to prevent relative movement between the first sleeve 113 and the second sleeve 114. The second locking member 117 clamps the second sleeve 114 to prevent relative movement between the second sleeve 113 and the third sleeve 115. The three sleeves 115 do not move relative to each other. For example, when it is necessary to adjust the length of the telescopic sleeve 110 to match the depth of the formation tank, the operator can pull the first sleeve 113 to extend or retract within the second sleeve 114 or pull the second sleeve 114 to extend or retract within the third sleeve 115, thereby freely adjusting the relative extension or retraction between the first sleeve 113 and the second sleeve 114, and between the second sleeve 114 and the third sleeve 115, to meet the different depths of the formation tank. At the same time, the operator can use the first locking member 116 to fix the extension or retraction length of the first sleeve 113 within the second sleeve 114, thereby preventing the first sleeve 113 from accidentally retracting or extending under external force. The second locking member 117 fixes the extension or retraction length of the second sleeve 114 within the third sleeve 115, thereby preventing the second sleeve 114 from accidentally retracting or extending under external force.

[0026] Furthermore, the upper gripper 130 includes a first gripping arm 131 and a second gripping arm 132. One end of the first gripping arm 131 passes through the first through groove 111 and is connected to the telescopic connecting rod 120. The second gripping arm 132 is located on one side of the first through groove 111, and one end of the second gripping arm 132 is fixedly connected to the third sleeve 115. In use, the operator squeezes the first gripping arm 131 and rotates it in the first through groove 111 towards the second gripping arm 132 to form a clamping closure. This causes the first gripping arm 131 to drive the telescopic connecting rod 120 to rotate clockwise, and the telescopic connecting rod 120 to drive the lower gripper. One of the clamping arms of 140 rotates to control the two clamping arms of the lower jaw 140 to form a clamping closure, thereby clamping the broken foil. After the two clamping arms of the lower jaw 140 have clamped the broken foil, the operator pushes the first clamping arm 131 to rotate away from the second clamping arm 132 in the first through groove 111 to form a separation opening. This causes the first clamping arm 131 to drive the telescopic connecting rod 120 to reverse, and the telescopic connecting rod 120 drives one of the clamping arms of the lower jaw 140 to rotate to control the two clamping arms of the lower jaw 140 to form a separation opening, thereby releasing the clamped broken foil.

[0027] Furthermore, to enable the first clamping arm 131 to automatically rotate in the first through groove 111 away from the second clamping arm 132 to form a separated open state with an automatic reset function, the upper clamp 130 also includes a first telescopic spring 133. The first telescopic spring 133 surrounds the outer tube wall of the third sleeve 115 near its top end, with one end of the first telescopic spring 133 fixedly connected to the first clamping arm 131 and the other end fixedly connected to the second clamping arm 132. This allows the first telescopic spring 133 to form an arc corresponding to the outer tube wall of the third sleeve 115. When the first telescopic spring 133 is not subjected to external force applied by the operator, it pulls the first clamping arm 131 to rotate in the first through groove 111 away from the second clamping arm 132 under the guidance of the outer tube wall of the third sleeve 115. And under the constraint of the first through groove 111... The first clamping arm 131 and the second clamping arm 132 are in a predetermined open state. The operator holds the first clamping arm 131 and the second clamping arm 132 and moves the first clamping arm 131 closer to the second clamping arm 132 so that the two clamping arms of the lower jaw 140 can clamp the foil fragments. After the lower jaw 140 holding the foil fragments is removed from the forming tank, the operator releases the first clamping arm 131. The first telescopic spring 133 automatically springs back, causing the first telescopic spring 133 to pull the first clamping arm 131 to rotate away from the second clamping arm 132 in the first through groove 111. Then, through the telescopic connecting rod 120, the two clamping arms of the lower jaw 140 are driven to separate and open to release the clamped foil fragments. This simplifies the operator's clamping operation. At the same time, when the two clamping arms of the lower jaw 140 contact the foil fragments, the first telescopic spring 133 can be compressed and deformed to absorb part of the impact force, avoiding deformation or breakage of the foil fragments due to rigid clamping.

[0028] Furthermore, to prevent the first telescopic spring 133 from pulling the first clamping arm 131 to rotate away from the second clamping arm 132 within the first through groove 111, thus creating a gap between the two clamping arms of the lower clamping jaw 140 and causing the clamped foil fragments to fall off, the upper clamping jaw 130 also includes two limiting posts 134 and a locking piece 135. One limiting post 134 is fixedly disposed on the upper surface of the first clamping arm 131, and the other limiting post 134 is fixedly disposed on the upper surface of the second clamping arm 132. One end of the locking piece 135 is rotatably connected to one of the connecting posts, and the other end of the locking piece 135 is engaged with the other limiting post 134. When the first clamping arm 131 approaches the second clamping arm 132 to form a clamping closure, the locking piece 135 fixes the first clamping arm 131 and the second clamping arm 132, thereby maintaining the clamping closure state of the upper clamping jaw 130 and the lower clamping jaw 140 and preventing the foil fragments from falling off.

[0029] Furthermore, the lower gripper 140 includes a third gripping arm 141 and a fourth gripping arm 142. One end of the third gripping arm 141 passes through the second through groove 112 and is connected to the telescopic connecting rod 120. The fourth gripping arm 142 is located on one side of the second through groove 112, and one end of the fourth gripping arm 142 is fixedly connected to the first sleeve 113. In use, the operator pinches the third gripping arm 141 and rotates it in the first through groove 111 towards the second gripping arm 142 to form a clamping closure. This causes the first gripping arm 141 to drive the telescopic connecting rod 120 to rotate clockwise, and the telescopic connecting rod 120 to drive the third gripping arm 141 to rotate clockwise. The second through slot 112 rotates towards the fourth clamping arm 142 to form a clamping closure, thereby clamping the broken foil. After the third clamping arm 141 and the fourth clamping arm 142 have finished clamping the broken foil, the worker releases the first clamping arm 131, and the first telescopic spring 133 automatically springs back, causing the first telescopic spring 133 to pull the first clamping arm 131 to rotate away from the second clamping arm 132 in the first through slot 111. Then, through the telescopic connecting rod 120, the third clamping arm 141 is driven to rotate away from the fourth clamping arm 142 to form a separation opening, thereby releasing the clamped broken foil.

[0030] Furthermore, to improve the service life of the first telescopic spring 133 and reduce its load, the lower gripper 140 also includes a second telescopic spring 143. The second telescopic spring 143 is elastically matched with the first telescopic spring 133. The second telescopic spring 143 surrounds the outer wall of the bottom end of the first sleeve 113, and one end of the second telescopic spring 143 is fixedly connected to the third clamping arm 141, while the other end is fixedly connected to the fourth clamping arm 142, so that the second telescopic spring 133 forms a connection with the first... The second telescopic spring 143, under the guidance of the outer wall of the first sleeve 113, pulls the third clamping arm 141 in the second through groove 112 away from the fourth clamping arm 142, and under the restriction of the second through groove 112, the third clamping arm 141 and the fourth clamping arm 142 are in the same open state at a predetermined angle, so as to prevent the third clamping arm 141 from deflecting due to uneven force, and ensure the accurate alignment of the first clamping arm 131 and the third clamping arm 141.

[0031] Furthermore, in order to better clean the broken foil that has settled at the bottom of the formation tank, the bottom of the third clamping arm 141 and the fourth clamping arm 142 are both equipped with brush plates 144. Multiple copper wires are evenly fixed on the brush plates 144 to form a steel brush. Workers can use the steel brush to sweep the bottom of the tank, thereby gathering the scattered small broken foil for centralized clamping.

[0032] Furthermore, to accommodate the telescopic length of the telescopic sleeve 110, the telescopic connecting rod 120 includes a first sleeve 121, a second sleeve 122, a third sleeve 123, a first connecting post 124, and a second connecting post 125. The length of the first sleeve 121 is adapted to the first sleeve 113, the length of the second sleeve 122 is adapted to the second sleeve 114, and the length of the third sleeve 123 is adapted to the third sleeve 115. Two first connecting grooves are formed opposite each other on the side wall of the second sleeve 122, and two second connecting grooves are formed opposite each other on the side wall of the third sleeve 123. The first sleeve 121 is fitted inside the second sleeve 122, and the second sleeve 122 is fitted inside the third sleeve 123. The first connecting post 124 passes through the top end of the first sleeve 121, and the second connecting post 125 passes through the top end of the second sleeve 122. The bottom end of the sleeve 121 is fixedly connected to the third clamping arm 141, and the top end of the third sleeve 123 is fixedly connected to the first clamping arm 131. When the telescopic sleeve 110 extends or shortens, the first clamping arm 131 and the third clamping arm 141 cooperate to pull the first sleeve 121 and the third sleeve 123 together, so that the first sleeve 121 extends and retracts in the second sleeve 122, and the second sleeve 122 extends and retracts in the third sleeve 123. At the same time, the first connecting post 124 slides along the length direction of the second sleeve 122 in the first connecting groove of the second sleeve 122, and the second connecting post 125 slides along the length direction of the third sleeve 123 in the second connecting groove of the third sleeve 123. When the third sleeve 123 rotates, the first connecting post 124 drives the second sleeve 122 to move in conjunction, and the second connecting post 125 drives the first sleeve 121 to move in conjunction.

[0033] Furthermore, the first locking element 116 includes a first locking sleeve 1161 and a first locking ring 1162. The vertical cross-section of the first locking sleeve 1161 is trapezoidal. One end of the first locking sleeve 1161 is fitted onto the bottom end of the second sleeve 114 to form an interference fit. The other end of the first locking sleeve 1161 has four axisymmetric first elastic grooves 11611. An elastic clamping flap is formed between the four first elastic grooves 11611. The elastic clamping flap of the first locking sleeve 1161 is threadedly connected to the first locking ring 1162. The first sleeve 113 is inserted into the first locking sleeve 1161. The elastic clamping flap of the first locking sleeve 1161 is compressed and expands radially to form an interference fit. After reaching the target extension length, the first locking ring 1162 is fastened to the elastic clamping flap of the first locking sleeve 1161 by a threaded connection, thereby preventing the elastic clamping flap of the first locking sleeve 1161 from further expanding radially and achieving locking.

[0034] Similarly, the second locking element 117 includes a second locking sleeve 1171 and a second locking ring 1172. The vertical cross-section of the second locking sleeve 1171 is trapezoidal. One end of the second locking sleeve 1171 is fitted onto the bottom end of the third sleeve 115 to form an interference fit. The other end of the second locking sleeve 1171 has four axisymmetric second elastic grooves 11711. An elastic clamping flap is formed between the four second elastic grooves 11711. The elastic clamping flap of the second sleeve 114 is threadedly connected to the second locking ring 1172. The second sleeve 114 is inserted into the second locking sleeve 1171. The elastic clamping flap of the second locking sleeve 1171 is compressed and expands radially to form an interference fit. After reaching the target extension length, the second locking ring 1172 is fastened to the elastic clamping flap of the second locking sleeve 1171 by a threaded connection, thereby preventing the elastic clamping flap of the second locking sleeve 1171 from further expanding radially and achieving locking.

[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
