Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery baking, in particular to a soft package clamping claw. Background Art

[0002] The existing clamping jaws usually clamp workpieces such as batteries by using air cylinders or hydraulic cylinders. Although this method has a simple structure, a sudden power outage or air supply interruption will cause the air cylinder or hydraulic cylinder to loosen, causing the workpiece to fall, resulting in unnecessary losses. Utility Model Content

[0003] The utility model aims to provide a soft-pack clamping jaw, which can improve the stability and reliability of clamping a workpiece, reduce the probability of the workpiece falling, and reduce the loss.

[0004] The embodiment of the utility model is achieved as follows:

[0005] In a first aspect, the utility model provides a soft bag clamp, comprising:

[0006] A clamping mechanism and a driving mechanism, wherein the clamping mechanism comprises a clamping unit, wherein the clamping unit comprises an elastic member and two clamping arms; the two clamping arms are rotatably matched, and the two clamping arms jointly define a clamping space that can be switched between a closed state and an open state; the elastic member is connected to at least one of the two clamping arms, and is used to drive the two clamping arms to rotate in a direction of approaching each other, so that the clamping space has a tendency to switch from the open state to the closed state;

[0007] The driving mechanism cooperates with the clamping mechanism to overcome the elastic force of the elastic member and drive the two clamping arms to rotate in a direction away from each other, so that the clamping space has a tendency to switch from the closed state to the open state.

[0008] In an optional embodiment, the clamping mechanism further includes a connecting plate; the number of the elastic members is two, one end of the two elastic members are connected to the connecting plate, and the other ends of the two elastic members are respectively connected to the two clamping arms.

[0009] Based on the above solution, two elastic parts cooperate with two clamping arms respectively, and each elastic part provides elastic force to control the rotation of the corresponding clamping arm, which is easy to assemble, and each elastic part works independently without affecting each other, and the cost of replacement is low.

[0010] In an optional embodiment, each clamp arm is rotatably connected to a force transmission rod, and the end of the force transmission rod away from the clamp arm is connected to the elastic member, and the elastic member is used to drive the corresponding clamp arm to rotate in a direction away from the other clamp arm through the force transmission rod.

[0011] Based on the above solution, by providing a force transmission rod, the angle between the force transmission rod and the clamp arm can be increased, and the space required in the length direction of the clamp arm is small, which facilitates the arrangement of the elastic member.

[0012] In an optional embodiment, the clamp mechanism further includes a base plate and a mounting plate; the connecting plate is fixedly connected to the mounting plate and the two are distributed on both sides of the base plate, the connecting plate and the mounting plate are slidably matched with the base plate at the same time, and the driving mechanism is connected to the connecting plate to drive the connecting plate and the mounting plate to rise and fall relative to the base plate at the same time; the two clamp arms both penetrate the base plate and are rotatably connected to the mounting plate;

[0013] The clamping jaw unit also includes two linkage components, both of which are installed on the base plate. The two linkage components cooperate with the two clamping arms respectively, and each of the linkage components is used to abut against the corresponding clamping arm when the connecting plate approaches the base plate to drive the two clamping arms to rotate in a direction away from each other, thereby switching the clamping space from the closed state to the open state.

[0014] Based on the above scheme, the connection plate drives the movement of the clamping unit, and multiple groups of clamping units can be set on the connection plate, so that the multiple groups of clamping units can more stably clamp the workpieces such as battery panels. At the same time, the connection plate drives the clamping unit to rise and fall synchronously, and the lifting movement of the connection plate can be converted into the rotation of the clamping arm through the linkage component, which makes rational use of the longitudinal and lateral spaces, is conducive to the layout of the workpiece, and improves the compactness of the overall structure.

[0015] In an optional embodiment, the linkage assembly includes a support rod and a reset member, one end of the support rod is rotatably connected to the base plate, and the reset member is simultaneously connected to the support rod and the base plate; the support rod is used to abut against the clamp arm when the connecting plate is close to the base plate;

[0016] When the support rod rotates in a first direction driven by the clamp arm, the support rod drives the two clamp arms to rotate in directions away from each other; when the connecting plate moves away from the base plate, the support rod rotates in a second direction opposite to the first direction and resets under the drive of the reset member.

[0017] Based on the above scheme, the linkage assembly has a simple structure, is easy to lay out, and has high assembly efficiency. In addition, the clamp arm drives the support rod to rotate during the descent process, and the support rod can also drive the clamp arm to rotate at the same time. The two cooperate with each other to realize the clamp arm rotating and opening, thereby releasing the solar panel, which is easy to operate.

[0018] In an optional embodiment, a limit block is provided on the base plate, and the limit block is used to abut against the support rod when the support rod is rotated and reset along the second direction, so as to limit the rotation range of the support rod in the second direction.

[0019] Based on the above scheme, when the reset member pulls the support rod to rotate, the support rod can abut against the limit block, thereby controlling the extreme position of the support rod, and the clamping arm applies force to the support rod under the action of the elastic member, and the support rod is limited by the limit block, thereby finally achieving the limitation of the clamping arm, avoiding excessive clamping force of the clamping arm to damage the solar panel.

[0020] In an optional embodiment, a slot is provided on the support rod; the force transmission rod and the clamp arm are rotatably matched via a rotating shaft, and the rotating shaft is engaged in the slot.

[0021] Based on the above solution, the card slot on the support rod is engaged with the clamp arm, which can limit the position of the clamp arm, improve the tightness of the clamp arm and the support rod, and also facilitate the linkage movement of the two, thereby improving the accuracy of control.

[0022] In an optional embodiment, the clamping mechanism further includes a straightening unit, wherein the straightening unit is mounted on the base plate, and the straightening unit is provided with a positioning space for accommodating a workpiece located in the clamping space.

[0023] Based on the above solution, when clamping workpieces such as solar panels, the workpiece enters the positioning space, which reduces shaking, improves the stability of the workpiece during clamping, and thereby reduces the risk of the workpiece falling off.

[0024] In an optional embodiment, the straightening unit includes two straightening plates, which are both connected to the base plate and arranged opposite to each other, and the positioning space is defined between the two straightening plates. The position of at least one of the two straightening plates and the base plate is adjustable, so as to adjust the width of the positioning space.

[0025] Based on the above solution, the structure of the straightening unit is simple, and the position of the straightening plate can be adjusted according to actual conditions, thereby adapting to the positioning of workpieces of different thicknesses and having a wide range of uses.

[0026] In an optional embodiment, the soft bag clamp also includes a frame, the number of the clamp mechanisms is multiple, and the multiple clamp mechanisms are all installed on the frame, and the driving mechanism cooperates with the multiple clamp mechanisms at the same time to drive the multiple clamp mechanisms to move synchronously.

[0027] Based on the above scheme, by setting up multiple clamping jaw mechanisms, multiple workpieces can be clamped at the same time, thereby improving the clamping capacity, improving the working efficiency and reducing the working cost.

[0028] The beneficial effects of the embodiments of the utility model are:

[0029] In summary, the soft-package clamp provided in this embodiment is explained by taking the clamping of a battery panel as an example. When the battery panel needs to be clamped, the driving mechanism drives the two clamp arms to rotate in a direction away from each other. The two clamp arms rotate to open the clamping space. After the battery panel is clamped by the clamping space, the driving mechanism cancels the external force applied to the clamp arms. Under the elastic force of the elastic member, the elastic member drives the two clamp arms to rotate in a direction close to each other, so that the two clamp arms clamp the battery panel. During the clamping process, the elastic member always provides elastic force to the clamp arms, so that the clamp arms always remain in the state of clamping the battery panel, that is, the two clamp arms are always in a normally closed state, which can reduce the probability of the battery panel falling and improve the stability and reliability of the clamping.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0041] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0042] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0043] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the prior art, when clamping workpieces such as soft-pack batteries or parts, general clamps are driven by cylinders, which require continuous air intake to maintain the clamping force. When the power is off or the air source is interrupted, the cylinder becomes loose and the workpiece loses its clamping force, which can easily cause the workpiece to fall and be damaged, resulting in unnecessary losses.

[0045] In view of this, the designer provides a soft-pack clamp, which is always in a normally closed state, can stably clamp the solar panel, is not easy to fall, has high safety, and is not prone to accidental falling and causing unnecessary losses.

[0046] Please combine Figure 1-Figure 4 In this embodiment, the soft bag clamp includes a clamp mechanism 100 and a driving mechanism 200. The clamp mechanism 100 includes a clamp unit 170. The clamp unit 170 includes an elastic member 171 and two clamp arms 172. The two clamp arms 172 are rotatably matched, and the two clamp arms 172 jointly define a clamping space 176 that can be switched between a closed state and an open state. The elastic member 171 is connected to at least one of the two clamp arms 172, and is used to drive the two clamp arms 172 to rotate in a direction close to each other, so that the clamping space 176 has a tendency to switch from an open state to a closed state.

[0047] The driving mechanism 200 cooperates with the clamping mechanism 100 to overcome the elastic force of the elastic member 171 and drive the two clamping arms 172 to rotate away from each other, so that the clamping space 176 has a tendency to switch from a closed state to an open state.

[0048] Based on the above, the working principle of the soft bag clamp provided in this embodiment is as follows:

[0049] Please combine Figure 5It should be noted that the soft-pack clamp can clamp various types of workpieces. In this embodiment, the soft-pack clamp clamps the battery panel as an example. In the initial state, the clamp arm 172 is only affected by the elastic force of the elastic member 171, and the two clamp arms 172 are in a closed state. When it is necessary to clamp the battery panel, the drive mechanism 200 overcomes the elastic force of the elastic member 171 and drives the two clamp arms 172 to rotate in a direction away from each other. The two clamp arms 172 rotate to open the clamping space 176. After the clamping space 176 is used to clamp the battery panel, the drive mechanism 200 cancels the external force applied to the clamp arm 172. Under the elastic force of the elastic member 171, the elastic member 171 drives the two clamp arms 172 to rotate in a direction close to each other, so that the two clamp arms 172 clamp the battery panel. During the clamping process, the elastic member 171 always provides elastic force to the clamping arm 172, so that the clamping arm 172 always remains in the state of clamping the solar panel, that is, the two clamping arms 172 are always in a normally closed state, which can reduce the probability of the solar panel falling and improve the stability and reliability of clamping.

[0050] The details of the soft bag clamping jaws of the embodiment of the present application are described below by way of examples.

[0051] Please combine Figure 1-Figure 3 In this embodiment, the soft bag clamp includes multiple clamp mechanisms 100, a driving mechanism 200 and a frame 300; the multiple clamp mechanisms 100 are installed on the frame 300, the driving mechanism 200 is installed on the frame 300 and is connected to the multiple clamp mechanisms 100 at the same time, and the driving mechanism 200 can drive the multiple clamp mechanisms 100 to move at the same time, so that the multiple clamp mechanisms 100 can synchronously clamp multiple solar panels or release multiple solar panels, thereby improving work efficiency.

[0052] For example, in this embodiment, the number of the clamping mechanisms 100 is sixteen, and the sixteen clamping mechanisms 100 are arranged side by side, and can clamp sixteen solar panels at the same time. It should be understood that in other embodiments, the number of the clamping mechanisms 100 is not limited to sixteen.

[0053] At the same time, in order to facilitate processing and manufacturing and reduce costs, in this embodiment, the structures of multiple clamping mechanisms 100 are set to be the same. In this embodiment, in order to avoid repeated descriptions, one clamping mechanism 100 is used as an example for detailed description.

[0054] Please combine Figure 2-Figure 3In this embodiment, optionally, the clamp mechanism 100 includes a connecting plate 110, a base plate 120, a mounting plate 130, a cam follower 140, a straightening unit 150, two guide units 160 and two clamp units 170. The cam follower 140 is connected to the connecting plate 110, and the cam follower 140 is used to connect with the driving mechanism 200. All base plates 120 are fixed on the frame 300, and the connecting plate 110 is slidably matched with the base plate 120 through two guide units 160. The two guide units 160 are arranged at intervals in the length direction of the connecting plate 110, and the mounting plate 130 is located on the side of the base plate 120 away from the connecting plate 110. The mounting plate 130 and the connecting plate 110 slide synchronously relative to the base plate 120 driven by the guide units 160. That is, the substrate 120 is located between the connecting plate 110 and the mounting plate 130, and the connecting plate 110 and the mounting plate 130 are connected together by the guide unit 160, and can slide synchronously relative to the substrate 120. Since there are two guide units 160, the guidance is stable. The straightening unit 150 is fixed to the substrate 120, and the straightening unit 150 is used to position the battery panel, thereby reducing the shaking of the battery panel during the clamping process and reducing the probability of the battery panel falling. The two clamping jaw units 170 are simultaneously cooperated with the connecting plate 110, the mounting plate 130 and the substrate 120. The two clamping jaw units 170 can cooperate to clamp the same battery panel or release the battery panel under the drive of the driving mechanism 200, and the clamping is more stable and not easy to loosen.

[0055] Optionally, each guide unit 160 includes a guide sleeve 161 and a guide rod 162, wherein the guide sleeve 161 is fixed on the base plate 120, the guide rod 162 is inserted into the guide sleeve 161 and slidably cooperates with the guide sleeve 161, and both ends of the guide rod 162 extend out of the guide sleeve 161, and both ends of the guide rod 162 are respectively fixedly connected to the connecting plate 110 and the mounting plate 130, so that when the driving mechanism 200 is connected to the cam follower 140 and drives the connecting plate 110 to move relative to the base plate 120, the mounting plate 130 is driven to move synchronously relative to the base plate 120 through the guide rod 162. The overall structure is compact and highly stable.

[0056] It should be understood that the guide sleeve 161 and the guide rod 162 can be matched through a linear bearing to reduce friction and make sliding more stable.

[0057] Please combine Figure 2-Figure 4Optionally, each clamping jaw unit 170 includes two elastic members 171, two clamping arms 172, two force transmission rods 173, two rotating shafts 174 and two linkage assemblies 175. Both clamping arms 172 are rotatably matched with the mounting plate 130, and the two clamping arms 172 are cross-arranged in a scissor-like shape. One end of each clamping arm 172 passes through the base plate 120 and extends toward the connecting plate 110. One end of each clamping arm 172 is rotatably connected to a force transmission rod 173 through a corresponding rotating shaft 174, and the other end of the force transmission rod 173 extends to a side away from the clamping arm 172, so that the two force transmission rods 173 are basically located on the outside of the two clamping arms 172. That is, the paired clamping arms 172 and force transmission rods 173 are rotatably matched through the corresponding rotating shaft 174. One end of each elastic member 171 is fixed on the connecting plate 110, and the other end is connected to the force transmission rod 173. For example, the elastic member 171 can be a tension spring, and the two ends of the elastic member 171 can be hooked on the connecting plate 110 and the force transmission rod 173 respectively, which is convenient for installation. The elastic member 171 is in a stretched state and always has elastic force to restore the deformation, so that it can drive the corresponding clamping arm 172 to rotate relative to the mounting plate 130, so that the two clamping arms 172 are close to each other, so that the clamping space 176 is always in a closed state. It should be understood that when one of the clamping arms 172 rotates in a first direction driven by the elastic member 171, the other clamping arm 172 rotates in a second direction opposite to the first direction driven by the other elastic member 171. In this way, the two clamping arms 172 rotate towards each other, similar to the movement of scissors. When the two clamping arms 172 rotate towards each other, the clamping space 176 between the two clamping arms 172 is reduced, and the battery panel located in the clamping space 176 can be clamped.

[0058] At the same time, the two linkage components 175 are respectively used in conjunction with the two clamping arms 172 of the same clamping jaw unit 170. The two linkage components 175 cooperate with the corresponding clamping arms 172 in the same manner. In this embodiment, the cooperation structure of one linkage component 175 and one clamping arm 172 is used as an example for description.

[0059] Please combine Figure 4Each linkage assembly 175 includes a fixed block 1751, a support rod 1752, a reset member 1753 and a limit block 1754. The fixed block 1751 is mounted on the base plate 120, and the support rod 1752 is rotatably mounted on the fixed block 1751. The support rod 1752 and the fixed block 1751 are connected by a reset member 1753. The reset member 1753 is a torsion spring, and the reset member 1753 makes the support rod 1752 always have a tendency to rotate in a set direction. The limit block 1754 is mounted on the fixed block 1751, and the limit block 1754 can abut against the support rod 1752, so that the support rod 1752 is always kept at a preset position under the action of the reset member 1753. That is, under the elastic force of the reset member 1753, the support rod 1752 rotates toward the set direction, and when it rotates to abut against the limit block 1754, the support rod 1752 stops rotating and remains at the position abutting against the limit block 1754. At the same time, a slot 1755 is provided on the support rod 1752.

[0060] When the clamping arm 172 and the corresponding linkage assembly 175 cooperate, the rotating shaft 174 is clamped in the slot 1755 on the support rod 1752, and the freedom of the rotating shaft 174 and the support rod 1752 in the length direction of the support rod 1752 is restricted, so that the rotating shaft 174 will not escape from the slot 1755.

[0061] Please combine Figure 4 and Figure 5 ,in, Figure 5 The direction indicated by the arrows ab in is the first direction. Figure 5The direction indicated by the arrow ba in the figure is the second direction, and the two directions are opposite. At the same time, for the convenience of description, the movement state of one clamp arm 172 is used for explanation, and the movement state of the other clamp arm 172 is just opposite. In the initial state, the driving mechanism 200 does not apply external force to the connecting plate 110, and the connecting plate 110 does not drive the clamp arm 172 to move relative to the base plate 120. Under the action of the elastic member 171, the clamp arm 172 has a tendency to rotate in the first direction, the clamp arm 172 is in a closed position, and the support rod 1752 is in a position abutting against the limit block 1754. It can be understood that, when the clamp arm 172 and the support rod 1752 are paired for explanation, the clamp arm 172 and the support rod 1752 both have a tendency to rotate in the first direction. When it is necessary to open the clamping space 176, the driving mechanism 200 is started, driving the connecting plate 110 to approach the base plate 120, and the connecting plate 110, the elastic member 171, the clamping arm 172, the force transmission rod 173, the rotating shaft 174 and the mounting plate 130 are synchronously lowered. Since the rotating shaft 174 is close to the base plate 120, and the support rod 1752 is installed on the base plate 120, the rotating shaft 174 presses the support rod 1752 to drive the support rod 1752 to rotate in a second direction opposite to the first direction. Since the support rod 1752 and the rotating shaft 174 cooperate through the slot 1755, and the freedom of the rotating shaft 174 in the length direction of the support rod 1752 is limited by the slot 1755, when the support rod 1752 rotates in the second direction, it drives the clamping arm 172 to rotate in the second direction, so that the clamping arm 172 rotates from the closed position to the open position, and finally the clamping space 176 is switched from the closed state to the open state. During this process, both the elastic member 171 and the reset member 1753 store elastic force for restoring deformation. When the clamping is completed, the driving mechanism 200 drives the connecting plate 110 to rise and reset. At this time, the support rod 1752 rotates along the first direction under the action of the reset member 1753, and the clamping arm 172 rotates along the first direction under the action of the elastic member 171. The two clamping arms 172 cooperate to clamp the battery panel, and under the action of the elastic member 171, the two clamping arms 172 are always in a state of clamping the battery panel, and the battery panel is not easy to fall off.

[0062] It should be understood that when the solar panel enters the clamping space 176, the solar panel also cooperates with the straightening unit 150. The straightening unit 150 plays a role in positioning the solar panel, reducing the shaking of the solar panel during the clamping process and reducing the probability of the solar panel falling off.

[0063] Optionally, the straightening unit 150 includes two straightening plates 151, which are arranged in parallel and spaced apart, one end of each straightening plate 151 is connected to the base plate 120, and the other end extends vertically, the mounting plate 130 is located between the two straightening plates 151, and a clearance area for avoiding the straightening plates 151 is provided on the mounting plate 130, and the width of the mounting plate 130 will not interfere with the positioning space 152 formed between the two straightening plates 151. When in use, the solar panel is inserted into the positioning space 152, thereby playing the role of straightening the solar panel.

[0064] Furthermore, the positions of the ends of the two straightening plates 151 connected to the substrate 120 are adjustable, so that the width of the positioning space 152 can be adjusted to accommodate the straightening of solar panels of different thicknesses. For example, multiple groups of fixing holes 121 are provided on the substrate 120, and the multiple groups of fixing holes 121 are arranged at intervals in the arrangement direction of the two straightening plates 151. The straightening plates 151 are selected to be connected to the fixing holes 121 at different positions, so that the distance between the two straightening plates 151 can be adjusted, and the adjustment is convenient. When the straightening plates 151 are aligned with the corresponding fixing holes 121, screws are used to pass through the fixing holes 121 and are screwed to the straightening plates 151, which is convenient for assembly.

[0065] In this embodiment, the driving mechanism 200 optionally includes a telescope 210, a guide rod 220, a connecting block 230 and a connecting rod 240. The fixed portion of the telescope 210 is mounted on the frame 300. The telescopic portion of the telescope 210 is connected to the connecting block 230. The connecting block 230 is simultaneously connected to the guide rod 220 and the connecting rod 240. The guide rod 220 is slidably matched with the frame 300. There are multiple guide rods 220 and connecting blocks 230. Multiple guide rods 220 cooperate to guide multiple clamping mechanisms 100 to rise and fall synchronously and guide stably. Multiple guide rods 220 are respectively connected to the connecting rod 240 through multiple connecting blocks 230. The connecting rod 240 is provided with a connecting groove. The cam followers 140 of multiple clamping mechanisms 100 are plugged into the connecting groove, which is convenient for connection.

[0066] It should be understood that the telescoping device 210 can be a cylinder, etc., which is easy to operate and precisely controlled.

[0067] The soft-package clamp provided in this embodiment keeps the frame 300 stationary during actual operation, and drives the multiple clamp mechanisms 100 to rise and fall synchronously relative to the frame 300 through the driving mechanism 200, so as to realize the transfer of multiple solar panels, with high operation efficiency. The clamping arm 172 of each clamp mechanism 100 is in a normally closed state during the process of clamping the solar panel, so the solar panel is not easy to escape from the clamping space 176, and is not easy to be damaged by falling.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
