Description

Technical Field

[0001] This application relates to the field of battery cell transport technology, and in particular to a battery cell transport safety blocking mechanism. Background Technology

[0002] With the rapid development of the lithium battery industry, the requirements for the efficiency and automation of cell production and transfer are becoming increasingly stringent. Currently, the industry typically uses a combination of cell trays and conveyor lines to achieve fully automated cell transfer. In the entire production process, the conveyor line plays a crucial role in connection and transmission, while the safety blocking mechanism is a vital component that ensures the cell trays accurately stop and are positioned at specific locations during transport. Its stable operation is essential for maintaining the efficiency and safety of the production line.

[0003] The existing safety blocking mechanism mainly consists of three key components: a lifting cylinder, a blocking plate, and a guide shaft. When the battery cell tray needs to stop or be transferred at a specific position, the lifting cylinder extends or retracts, causing the blocking plate to rise to the blocking position or descend to the release position, thereby achieving the blocking or release operation of the battery cell tray. The guide shaft closely cooperates with the movement of the blocking plate, providing stable and precise lifting guidance.

[0004] However, when the battery cell tray comes into contact with the blocking mechanism, the force exerted by the battery cell tray is directly transmitted to the cylinder and guide shaft through the blocking plate. Especially when the weight of the battery cell tray exceeds 300 kg, the large force exerted on the cylinder and guide shaft may damage the cylinder and guide shaft bearings, leading to a decrease in the bearing precision of the guide shaft. This can easily cause the lifting and lowering of the safety blocking mechanism to become stuck or damaged, making it unable to block the battery cell tray properly. Utility Model Content

[0005] In order to overcome at least one of the defects described in the prior art, this application provides a battery cell transportation safety blocking mechanism, in which the force exerted by the battery cell tray on the blocking member is transmitted to the base through the support member, reducing the force transmitted to the drive component and avoiding problems such as jamming when the blocking member is raised or lowered due to damage to the drive component.

[0006] The technical solution adopted in this application to solve its problem is:

[0007] A battery cell transport safety blocking mechanism includes,

[0008] Base;

[0009] A blocking assembly includes a blocking member and a support member. The blocking member has a blocking surface and a support surface that are opposite to each other along the conveying direction. The support member is disposed on the base and connected to the blocking member to support the support surface.

[0010] A driving assembly is configured to drive the blocking piece to move up and down.

[0011] According to a preferred technical scheme of the present application, the blocking piece comprises a blocking plate, and the blocking surface and the supporting surface are formed on two sides of the blocking plate respectively.

[0012] According to a preferred technical scheme of the present application, two supporting pieces are arranged at two ends of the blocking plate respectively, and each of the supporting pieces comprises a first supporting plate segment, an abutting plate segment and a second supporting plate segment.

[0013] According to a preferred technical scheme of the present application, a wear-resistant piece is arranged between the supporting piece and the blocking plate.

[0014] According to a preferred technical scheme of the present application, the bottom of the supporting piece further comprises a bottom plate, and the bottom plate is arranged on the base.

[0015] According to a preferred technical scheme of the present application, the blocking piece further comprises a connecting plate, one end of the connecting plate is connected to the lower end of the blocking plate, and the connecting plate is connected to the blocking plate at a right angle.

[0016] According to a preferred technical scheme of the present application, the driving piece comprises a driving cylinder, the driving cylinder comprises a cylinder body and a piston rod, the cylinder body is arranged on the base, one end of the piston rod is connected to the cylinder body through a piston, and the other end of the piston rod is formed as the power output end.

[0019] Preferably, the blocking surface is provided with a buffer.

[0020] In summary, the battery cell transportation safety blocking mechanism has the following technical effects:

[0021] 1) The support member is arranged on the base to support the support surface of the blocking plate. When the battery cell tray collides with the blocking member at a certain speed and inertia, the battery cell tray first contacts the blocking surface, and the blocking surface uniformly transmits most of the force of the battery cell tray to the support surface. Since the support surface is supported by the support member, the support surface can transmit the force to the support member, and then the support member transmits and disperses the force to the base. At this time, the support member stably supports the support surface of the blocking member, ensuring that the blocking member can withstand the corresponding impact force when blocking the battery cell and keeping the position stable.

[0022] 2) The battery cell tray most of the force is transmitted to the base and the rack of the transportation line through the support member, reducing the force transmitted to the driving assembly by the blocking member, avoiding damage to the driving assembly and causing the blocking member to be stuck, and then effectively blocking the battery cell tray, avoiding the battery cell from falling accidentally and causing damage to the battery cell.

DETAILED DESCRIPTION

[0028] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. ​

[0029] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0031] Referring to Figures 1 to 3 The present application discloses a kind of battery transport safety blocking mechanism, it includes base 10, blocking component and drive component.Specifically, blocking component includes blocking piece 11 and support piece 12, referring to Figure 1 And Figure 2 Blocking piece 11 has mutually divergent blocking surface 13 and support surface 14 along conveying direction.Wherein, support piece 12 is arranged on base 10, and is connected with blocking piece 11, to support support surface 14.In addition, drive component is used to drive blocking piece 11 to lift.

[0032] On the basis of this structure, when using the battery transport safety blocking mechanism of the present application, the base 10 of the battery transport safety blocking mechanism can be installed on the rack of battery transport line.When it is needed to block the battery tray on the transport line, drive component will drive blocking piece 11 to rise, and after blocking piece 11 rises, blocking surface 13 is located in front of battery tray along conveying direction, and blocking battery tray continues to move forward.

[0033] When it is needed to release battery tray, drive component starts and drives blocking piece 11 to descend, so that blocking surface 13 is lower than the conveying plane of battery tray, and battery tray can pass through the position of blocking mechanism smoothly.When another batch of batteries is transported to the position that needs to be blocked, drive component drives blocking piece 11 to rise again, and restores to blocking state, so that the intermittent blocking control in the process of battery transport is realized.

[0034] Wherein, since battery tray is hindered by blocking plate 111 in horizontal direction, it will generate a reaction force in horizontal direction, i.e. impact force, to blocking plate 111;At the same time, since battery tray is acted by gravity in vertical direction, it will also generate a downward pressure to blocking plate 111.The resultant of the two forces is that the force exerted by battery tray to blocking plate 111 is towards front and downward.

[0035] It should be noted that in the prior art, the blocking piece 11 is driven to lift by the driving cylinder, and is guided to lift by the guide shaft 24. When the blocking plate 111 is subjected to the force of the battery tray towards the lower front, the force will act directly on the driving cylinder at the bottom of the blocking plate 111 and the guide shaft 24 through the blocking plate 111. As the mass of the battery tray increases, the force acting on the driving cylinder and the guide shaft 24 will increase significantly, which will cause the piston rod 21 of the driving cylinder or the bearing of the guide shaft 24 to be damaged, and further cause the guide of the blocking plate 111 to malfunction or the lifting to be stuck.

[0036] And the application sets the support piece 12 on the base 10 to support the support surface 14 of the blocking plate 111. When the battery tray rushes to the blocking piece 11 at a certain speed and inertia, the battery tray first contacts the blocking surface 13, and the blocking surface 13 uniformly transmits most of the force of the battery tray to the support surface 14 during the contact process. Since the support surface 14 is supported by the support piece 12, the support surface 14 can transmit the force to the support piece 12, and then transmit and disperse it to the base 10 by the support piece 12. At this time, the support piece 12 stably supports the support surface 14 of the blocking piece 11, ensuring that the blocking piece 11 can withstand the corresponding impact force when blocking the battery, and keeping its position stable.

[0037] Therefore, since most of the force of the battery tray acting on the blocking piece 11 is guided and transmitted to the base 10 and the rack of the transportation line by the support piece 12, the force transmitted to the driving assembly by the blocking piece 11 can be reduced, avoiding damage to the driving assembly and causing the lifting of the blocking piece 11 to be stuck, thereby effectively blocking the battery tray and avoiding the problem of accidental falling of the battery of the battery tray and causing damage to the battery.

[0038] As a preferred technical solution of the application, the blocking piece 11 includes the blocking plate 111, and the blocking surface 13 and the support surface 14 are formed on the two sides of the blocking plate 111. The support piece 12 includes the first support plate segment 121, and the first support plate segment 121 abuts against the support surface 14 to support the support surface 14.

[0039] Therefore, the first support plate segment 121 abuts against the support surface 14 of the blocking plate 111, providing a solid support structure for the blocking plate 111. When the battery cell tray exerts a force on the blocking plate 111, the support surface 14 transmits the force to the first support plate segment 121, which in turn disperses the force onto the base 10. This support method can effectively resist the impact force and pressure brought by the battery cell tray, ensuring that the blocking plate 111 does not deform or displace excessively under stress, maintaining the accuracy and stability of its blocking position, thereby ensuring the reliability and durability of the blocking mechanism, reducing damage to the mechanism caused by uneven or excessive stress, prolonging the service life of the mechanism, and providing strong protection for the safety of the battery cells during transportation, reducing the risk of damage to the battery cells due to accidental transportation.

[0040] As a preferred technical solution of the present application, two support members 12 are provided, and the two support members 12 are respectively arranged at the two ends of the blocking plate 111. Specifically, the support member 12 further includes a connecting plate segment 122 and a second support plate segment 123, and the first support plate segment 121 and the second support plate segment 123 are respectively connected to the two sides of the connecting plate segment 122; wherein the first support plate segment 121 and the second support plate segment 123 are oppositely arranged and spaced to form a guide interval 125, and the two ends of the blocking plate 111 are respectively installed in the guide interval 125.

[0041] On the basis of this structure, during assembly, first, the base 10 of the battery cell transportation safety blocking mechanism is fixed on the rack of the battery cell transportation line according to the predetermined position, ensuring that the entire mechanism is firmly and stably installed, and each component is in the initial state. Then, the two ends of the blocking plate 111 are respectively inserted into the guide interval 125 formed by the two support members 12, so that the blocking plate 111 is tightly connected with the support members 12, and it is ensured that the blocking plate 111 can move up and down within the guide interval 125, and at the same time, the first support plate segment 121 is completely attached to the support surface 14 of the blocking plate 111, preparing for subsequent force support.

[0042] When the battery cell tray on the transportation line approaches the blocking mechanism and needs to be blocked, the driving assembly is started to drive the blocking plate 111 to slide upward along the guide interval 125. As the blocking plate 111 rises, its blocking surface 13 gradually moves to a suitable position in front of the battery cell tray in the conveying direction. When the battery cell tray contacts the blocking surface 13, the blocking plate 111 bears the impact force and pressure from the battery cell tray. At this time, since the two ends of the blocking plate 111 are stably installed in the guide interval 125 of the support member 12, and the first support plate segment 121 provides strong support to the support surface 14 of the blocking plate 111, the blocking plate 111 can stably block the battery cell tray from moving forward, making it stop at the predetermined position, ensuring that the battery cell tray is accurately positioned according to the process during transportation.

[0043] Two support pieces 12 are respectively arranged at both ends of the blocking plate 111 and oppositely arranged with the first support plate segment 121 and the second support plate segment 123 to form a guide interval 125, which provides a precise guide path for the lifting movement of the blocking plate 111. This makes the blocking plate 111 stably rise and fall along the predetermined trajectory under the action of the driving assembly, avoids the deviation, shaking or jamming of the blocking plate 111 during the movement process, ensures the accuracy and reliability of the action of the blocking mechanism, and thus ensures that the battery cell tray can be accurately blocked and released each time, and improves the stability and working efficiency of the whole transportation system.

[0044] In addition, since the two support pieces 12 are respectively arranged at both ends of the blocking plate 111, the symmetrical support structure can balance and disperse the impact force and pressure received by the blocking plate 111 at both ends, further transmit the force to the base 10 and the transportation line rack, effectively prevent the blocking plate 111 from being deformed or damaged due to excessive local force, and greatly enhance the ability of the blocking plate 111 to resist external force.

[0045] It should be noted that the support piece 12 can be made of high-strength aluminum alloy plate, stainless steel plate or other metal parts through sheet metal bending process. The support piece 12 made in this way can withstand a large external force load and will not easily deform or bend under long-term frequent stress, thereby stably supporting the blocking plate 111 and ensuring the reliable operation of the whole blocking mechanism.

[0046] As a preferred technical solution of the present application, referring to Figure 3 A wear-resistant piece 15 is arranged between the support piece 12 and the blocking plate 111.

[0047] On the basis of this structure, when assembling the battery cell transportation safety blocking mechanism, the wear-resistant piece 15 is first installed on the surface of the blocking plate 111 in contact with the support piece 12. For example, the wear-resistant piece 15 can be pasted, inlaid or bolted to ensure that the wear-resistant piece 15 is tightly attached to the blocking plate 111 and the support piece 12 and will not be displaced or fall off during the lifting of the blocking plate 111.

[0048] When the driving assembly drives the blocking plate 111 to lift, the blocking plate 111 lifts along the guide interval 125 of the support piece 12, and at this time the wear-resistant piece 15 plays a role of buffering and reducing friction between the blocking plate 111 and the support piece 12. The two ends of the blocking plate 111 stably slide in the guide interval 125 formed by the support piece 12, and the wear-resistant piece 15 bears the friction force between the blocking plate 111 and the support piece 12, so as to ensure that the blocking plate 111 can smoothly reach the predetermined blocking position and effectively block the battery cell tray from continuing to move forward.

[0049] Therefore, the wear-resistant piece 15 effectively reduces the degree of wear between the blocking plate 111 and the support piece 12, prolongs the service life of the blocking plate 111 and the support piece 12, and reduces the frequency of replacement or maintenance due to component wear. At the same time, since the wear-resistant piece 15 generally has a lower friction coefficient, the blocking plate 111 is more smooth during lifting, and the required driving force is smaller. This not only helps to improve the working efficiency of the driving assembly, but also avoids the problem of blocking plate 111 jamming or deviation caused by excessive friction.

[0050] Specifically, the wear-resistant piece 15 is a PE wear-resistant strip, and the PE wear-resistant strip is arranged in a U-shaped structure on the inner side of the support piece 12, so that it can effectively disperse the friction force in the contact area between the blocking plate 111 and the support piece 12. In addition, the wear-resistant piece 15 can also be made of PTFE wear-resistant material of the prior art.

[0051] As a preferred technical solution of the present application, the bottom of the support piece 12 is further provided with a bottom plate 124, and the bottom plate 124 is installed on the base 10.

[0052] On the basis of this structure, during installation, the bottom plate 124 is first accurately placed on the corresponding installation position of the base 10, and is connected by bolt connection, welding or other connection methods to ensure that the bottom plate 124 is stably connected with the base 10, forming a reliable bottom support structure.

[0053] Among them, the bottom plate 124 is installed at the bottom of the support piece 12 and connected with the base 10, which greatly increases the stability of the support piece 12. When the blocking plate 111 is frequently lifted and bears the force from the battery tray, the bottom plate 124 can prevent the support piece 12 from shaking, tilting and other unstable conditions, and ensure that the support piece 12 provides accurate and stable guiding and supporting effect for the blocking plate 111.

[0054] In addition, when the battery tray exerts a force on the blocking plate 111, the force will be transmitted to the support piece 12 through the blocking plate 111, and the bottom plate 124 at the bottom of the support piece 12 can more evenly and effectively disperse these forces to the base 10.

[0055] As a preferred technical solution of the present application, referring to Figure 2 , the blocking piece 11 further comprises a connecting plate 112, one end of the connecting plate 112 is connected to the lower end of the blocking plate 111, and the connecting plate 112 is connected with the blocking plate 111 at a right angle. Among them, the bottom of the connecting plate 112 is provided with a connecting seat 113, the driving assembly comprises a driving piece, and the power output end of the driving piece is connected with the connecting seat 113 and is used to drive the blocking piece 11 to lift.

[0056] On the basis of the structure, when assembling, the blocking plate 111 is connected with the connecting plate 112, to ensure that the two are connected at right angles and firmly connected, specifically, they can be connected by welding or high-strength bolt connection, etc., to form a stable overall structure. Then, the connecting seat 113 is installed at the bottom of the connecting plate 112, to ensure that the installation position is accurate and the connection is reliable, so as to be connected with the driving part of the driving assembly in the subsequent stage.

[0057] Then the driving part is installed at a suitable position, generally fixed on the base 10 or the rack of the battery cell conveying line, etc. stable support structure, and then the power output end of the driving part is connected with the connecting seat 113, to realize the driving function of the blocking part 11.

[0058] Therefore, the power output by the driving part can stably drive the blocking plate 111 to move up and down along the predetermined track. This helps to accurately control the rising height and lowering position of the blocking plate 111, to ensure that the blocking plate 111 can be accurately located in front of the battery cell tray in the conveying direction each time it rises, to realize effective blocking, and can be accurately lowered to the appropriate position when released, so that the battery cell tray can pass smoothly, thereby improving the accuracy and reliability of the operation of the whole battery cell conveying safety blocking mechanism.

[0059] In addition, the blocking plate 111 and the connecting plate 112 can be made of a high-strength aluminum alloy plate, a stainless steel plate or other metal parts, which are made by sheet metal bending process. They can also be made of two aluminum alloy plates, stainless steel plates or other metal parts connected by welding or riveting. The support part 12 made in this way can withstand a large external force load and will not easily deform or bend under long-term frequent stress.

[0060] As a preferred technical solution of the present application, the driving part includes a driving cylinder, specifically, the driving cylinder includes a cylinder body 20 and a piston rod 21, wherein the cylinder body 20 is installed on the base 10, one end of the piston rod 21 is slidably connected in the cylinder body 20, and the other end of the piston rod 21 is formed as a power output end.

[0061] In this way, the driving cylinder provides power through the extension and retraction of the piston rod 21, to drive the blocking part 11 to rise and fall. This power output method can accurately and effectively change the position of the blocking plate 111, so that it can rise when needed to block the battery cell tray, and can fall when released, to meet the basic functional requirements of the intermittent blocking control of the tray during the battery cell conveying process, and to ensure the orderly progress of the conveying process.

[0062] The driving cylinder can be a gas cylinder or a hydraulic cylinder. In addition, the driving member can also be an electric push rod, and when the push rod of the electric push rod is elongated, an upward force can be applied to the connecting seat 113 through the power output end. Since the connecting seat 113 is connected to the connecting plate 112, and the connecting plate 112 is stably connected to the blocking plate 111, the upward force will drive the blocking plate 111 to move stably upward along the guide interval 125 of the support member 12.

[0063] As a preferred technical solution of the present application, the driving assembly further comprises two guide members 22, and the two guide members 22 are respectively arranged on both sides of the driving member. Specifically, the guide member 22 comprises a linear bearing 23 and a guide shaft 24, wherein the linear bearing 23 is installed on the base 10, the guide shaft 24 is installed on the linear bearing 23, and the end of the guide shaft 24 is connected to the connecting plate 112. The guide shaft 24 is used to guide the linear motion of the connecting plate 112.

[0064] On the basis of this structure, when assembling, first, the two linear bearings 23 are respectively installed on the corresponding positions of the base 10, which can be fixed by bolt connection or other stable connection mode to ensure that the linear bearing 23 is tightly combined with the base 10. Then, the guide shaft 24 is inserted into the corresponding linear bearing 23, so that the guide shaft 24 can smoothly slide in the linear bearing 23, and at the same time, the perpendicularity of the guide shaft 24 should meet the requirements to avoid the inclination and other conditions affecting the subsequent motion guiding effect.

[0065] Then, the end of the guide shaft 24 is connected to the connecting plate 112, which can be connected by welding, bolt connection or other connection mode to ensure that the connection is firm and will not affect the force transmission between the guide shaft 24 and the connecting plate 112 and the coordination of linear motion.

[0066] When the driving member drives the connecting plate 112 to rise through the power output end, the guide shaft 24 connected to the connecting plate 112 will move with the connecting plate 112. Since the guide shaft 24 is installed on the linear bearing 23 and can only slide linearly along the linear bearing 23, the guide shaft 24 will constrain the motion trajectory of the connecting plate 112, so that it moves stably upward in a straight line direction; the blocking plate 111 also rises synchronously due to the stable connection with the connecting plate 112.

[0067] Therefore, the guide 22 formed by the guide shaft 24 and the linear bearing 23 provides precise linear motion trajectory guidance for the lifting movement of the connecting plate 112 and the whole blocking piece 11, thereby improving the repeated positioning accuracy of the battery cell tray on the conveying line. During the driving of the blocking piece 11 by the driving piece, deviation, shaking or distortion is avoided, so that the blocking plate 111 can be accurately lifted to the predetermined blocking position and lowered to the release position each time, thereby ensuring the accuracy and reliability of the blocking and release operation of the battery cell tray and improving the working accuracy of the whole battery cell conveying safety blocking mechanism.

[0068] It should be noted that since the guide 22 and the driving piece are arranged at the bottom of the connecting plate 112, when the blocking piece 11 is subjected to the force of the battery cell tray, part of the force is transmitted to the guide shaft 24 and the linear bearing 23 through the connecting plate 112. When the force is too large, the accuracy of the linear bearing 23 will decrease, which will easily cause the blocking piece 11 to be stuck during lifting.

[0069] However, the application transmits and disperses most of the force of the blocking piece 11 to the base 10 by arranging the support piece 12 at both ends of the blocking piece 11, avoids the guide shaft 24 and the linear bearing 23 from bearing too much load, ensures the accuracy of the linear bearing 23, and thereby ensures the smooth lifting of the blocking piece 11.

[0070] As a preferred technical solution of the application, the connecting plate 112 and the blocking plate 111 are provided with a reinforcing piece 16, and the two ends of the reinforcing piece 16 are connected to the support surface 14 and the connecting plate 112, respectively.

[0071] On the basis of this structure, when assembling, one end of the reinforcing piece 16 can be connected to the support surface 14 of the blocking plate 111, and the connection can be realized by welding, riveting or the like, and then the other end of the reinforcing piece 16 is connected to the connecting plate 112.

[0072] The reinforcing piece 16 can be a reinforcing rib, a metal angle steel or the like.

[0073] Therefore, the reinforcing piece 16 can enhance the connection strength between the blocking plate 111 and the connecting plate 112. The reinforcing piece 16 connects the support surface 14 and the connecting plate 112 to form a stable triangular structure, which can effectively disperse stress and greatly improve the overall structural strength of the blocking piece 11, preventing the connection between the blocking plate 111 and the connecting plate 112 from loosening, deforming or breaking.

[0074] As a preferred technical solution of the application, the blocking surface 13 is provided with a buffer piece 17.

[0075] On the basis of the structure, the buffer 17 can be closely combined with the blocking surface 13 by means of sticking, inlaying or bolt fixing, and the buffer 17 is ensured to protrude from the blocking surface 13.

[0076] The buffer 17 can be a buffer pad of rubber or foam material, and can be uniformly stuck on the blocking surface 13 by using strong glue, so as to ensure that the buffer 17 covers the main area that can contact the battery tray, and in the installation process, attention should be paid to avoid wrinkles, bubbles and other conditions of the buffer 17, so as to avoid affecting the buffering performance.

[0077] When the battery tray contacts the blocking surface 13, the buffer 17 is first contacted, and the buffer 17 will be elastically deformed under the extrusion of the battery tray. The deformation will gradually absorb the kinetic energy of the battery tray, so that the speed of the battery tray is gradually reduced until it stops. When the battery tray is released, the blocking plate 111 is lowered, the buffer 17 returns to the original state, and waits for the next blocking operation.

[0078] Therefore, the buffer 17 can effectively absorb and buffer the impact force when the battery tray hits the blocking plate 111, and reduce the damage to the blocking plate 111 and the battery tray itself.

[0079] The technical means disclosed in the application scheme is not limited to the technical means disclosed in the above embodiments, and also includes the technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary skilled in the art, without departing from the principle of the application, some improvements and refinements can be made, and these improvements and refinements are also considered as the protection scope of the application.
