Description

TECHNICAL FIELD

[0001] The application relates to the technical field of battery production, in particular to a battery production positioning mechanism. BACKGROUND

[0002] At present, plastic trays are usually used for the transfer of battery cells during transportation. For the positioning of the battery cell tray in the corresponding position, a combination of a three-rod air cylinder, a positioning pin fixing mechanism and a positioning pin is usually adopted. During positioning, the three-rod air cylinder drives the positioning pin fixing mechanism to lift, and then the positioning pin fixing mechanism drives the positioning pin to lift, so as to complete the positioning of the battery cell tray. The three-rod air cylinder has a guide rod inside, which cooperates with the linear bearing of the cylinder body to effectively bear the radial force in the jacking process, that is, the force perpendicular to the axial direction of the guide rod.

[0003] However, since there are assembly errors between the positioning pin fixing mechanism and the three-rod air cylinder and between the positioning pin fixing mechanism and the positioning pin, the two kinds of assembly errors are continuously added in the whole transmission system, which finally leads to the decline of the positioning accuracy of the positioning pin to the battery cell tray. The decline of the positioning accuracy of the positioning pin to the battery cell tray may cause problems such as impact or short circuit when the mechanical hand grabs the battery cell on the battery cell tray due to positional deviation.

[0004] At the same time, the error accumulation in the transmission system will cause a large deviation between the positioning pin and the positioning hole of the battery cell tray, which will cause the guide rod and the linear bearing to bear a large radial force. Due to the limitation of the surrounding space, the linear bearing installed on the air cylinder cannot choose a larger diameter product. The linear bearing with a smaller diameter can only bear a limited radial force, and the liner sleeve of the linear bearing is easily damaged due to bearing a radial force beyond its capacity. Once the liner sleeve of the linear bearing is damaged, the whole positioning device cannot work normally, and the related transportation equipment also fails, which finally leads to the failure of the production and transportation process, and further causes the loss of production capacity.

[0019] As a preferred technical solution of the present application, the top end of the first guide sleeve is provided with an abutting step, and the abutting step is used for abutting against the upper end surface of the connecting step to limit the movement stroke of the positioning member.

[0029] For better understanding and implementation, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying 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.

[0031] 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 terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0032] Referring to Figure 1 and Figure 2 , the present application discloses a battery production positioning mechanism, which comprises a positioning member, a driving assembly 10 and a guide assembly. Specifically, the positioning member is provided with a first connecting portion and a positioning portion, and the positioning portion is used to position the battery cell tray. The driving assembly 10 has a power output end 11, and the power output end 11 is provided with a second connecting portion, wherein the second connecting portion is detachably connected with the first connecting portion, and the driving assembly 10 is used to drive the positioning member to ascend or descend, so as to position or disengage the positioning portion from the battery cell tray. In addition, the guide assembly is used to guide the positioning member to ascend or descend.

[0033] On the basis of this structure, when the battery production positioning mechanism of the present application is used, it can be installed on the rack of the battery cell conveying line. After the battery cell tray is stopped at a specific position of the battery cell conveying line, the battery production positioning mechanism of the present application can position the battery cell tray at the specific position through the positioning member, and then the battery cell on the battery cell tray can be grabbed by a mechanical hand to move the single battery cell to other production stations for assembly, detection and other operations.

[0034] When the positioning operation of the battery cell tray is needed, the driving assembly 10 is first started, and the power output end 11 of the driving assembly 10 drives the positioning member to ascend under the guidance of the guide assembly. When the positioning member ascends to a certain height, the positioning portion of the positioning member contacts the battery cell tray and precisely positions the battery cell tray. At this time, the battery cell tray is fixed at the predetermined position, so that the subsequent production process can be accurately and correctly performed.

[0035] When the production process is completed, the driving assembly 10 is started again and drives the positioning member to descend, so that the positioning part is separated from the contact with the battery tray, and the conveying line can move the battery tray away for the next production process or transportation to other stations.

[0036] It should be noted that in the existing related equipment, the positioning pin is first installed on the fixed frame, and then the fixed frame is driven to rise by the cylinder, so as to realize the positioning of the battery tray by the positioning pin. However, this installation and transmission mode causes the assembly errors between the positioning pin and the fixed frame, and between the cylinder and the fixed frame to be accumulated, resulting in the decline of the positioning accuracy of the battery tray by the positioning pin, and further causing the problems of impact or short circuit when the mechanical hand grabs the battery due to the positional deviation.

[0037] However, the present application directly drives the positioning member to rise and fall by the driving assembly 10 to position the battery tray, and the positioning part of the positioning member directly acts on the battery tray to realize positioning, thereby reducing the assembly errors caused by the connection of multiple components in the middle and the superposition, and more accurately positioning the battery tray, ensuring the accuracy of the position of the battery in the subsequent production operation, avoiding the abnormality of the mechanical hand grabbing due to the insufficient positioning accuracy, and improving the reliability of the entire production link and the product quality.

[0038] Meanwhile, the present application cancels the structure for guiding the rise and fall of the cylinder by the linear bearing and the guide rod in the existing equipment, and directly guides the rise and fall of the positioning member by setting the guide assembly. The guide assembly plays the role of accurately guiding the rise and fall of the positioning member, avoiding the deviation or shaking of the positioning member during the rise and fall, so as to ensure the accuracy of the positioning. In this way, the risk of damaging the liner bushing of the linear bearing due to excessive force can be reduced, the production capacity loss caused by the damage of the components can be effectively avoided, and the efficient and orderly development of the entire battery production and transportation link can be ensured.

[0039] The second connecting part of the power output end 11 and the first connecting part of the positioning member are detachably connected, which not only ensures the stability of the two during work, but also facilitates the disassembly operation during maintenance or replacement of components.

[0040] As a preferred technical solution of the present application, the driving assembly 10 comprises a driving cylinder, specifically, the driving cylinder comprises a cylinder body and a piston rod 12, wherein the other end of the piston rod 12 is formed into the power output end 11.

[0041] On the basis of the structure, when the battery cell tray needs to be positioned, the driving cylinder starts to work to drive the piston rod 12 to extend and retract. Specifically, the driving cylinder can be a gas cylinder, a liquid cylinder, etc. In operation, the corresponding power medium (for example, if it is a gas cylinder, compressed air is introduced; if it is a liquid cylinder, hydraulic oil is introduced) is introduced into the cylinder body. Under the action of pressure, the piston rod 12 starts to extend outward from the cylinder body. Since the other end of the piston rod 12 is formed as a power output end 11, and the power output end 11 is detachably connected with the first connecting part of the positioning member, as the piston rod 12 extends, the positioning member connected therewith starts to move.

[0042] At the same time that the piston rod 12 extends, the positioning member moves stably upward along the predetermined vertical direction under the guidance of the guide assembly until it contacts and connects with the positioning structure of the battery cell tray, thereby positioning the battery cell tray and firmly fixing the battery cell tray at the predetermined production position, facilitating the smooth development of subsequent production processes such as battery cell assembly, detection, etc.

[0043] When the corresponding production process is completed, the driving cylinder receives the instruction signal from the control system again, changes the flow direction of the power medium (for example, for a pneumatic cylinder, changes the air inlet and exhaust direction of compressed air; for a hydraulic cylinder, changes the flow direction of hydraulic oil), so that the piston rod 12 starts to retract into the cylinder body, driving the positioning member to descend along the guide assembly and gradually disengage from the battery cell tray, so that the battery cell tray can be removed for the next production process or transported to other stations.

[0044] Therefore, through the extension and retraction movement of the piston rod 12, the positioning and disengagement operation between the positioning member and the battery cell tray can be accurately controlled, meeting the requirements for the position of the battery cell tray at different stages of the battery production process and realizing an automatic positioning process.

[0045] As a preferred technical solution of the present application, referring to Figure 2 and Figure 3 , the guide assembly includes a first guide sleeve 30 and a mounting seat 31. Specifically, the first guide sleeve 30 is connected to the mounting seat 31, and the mounting seat 31 is connected to the cylinder body. The first guide sleeve 30 is sleeved on the outer periphery of the positioning member and the piston rod 12.

[0046] On the basis of the structure, when the positioning mechanism is assembled, the positioning member is first installed on the power output end 11 of the piston rod 12, then the mounting seat 31 is connected to the cylinder body to ensure firm connection, and then the first guide sleeve 30 is connected to the mounting seat 31 to fix the position of the first guide sleeve 30 and enable it to work stably.

[0047] When the driving cylinder starts to work, the piston rod 12 extends outward and drives the positioning member to rise, and the positioning member and the piston rod 12 move upward along the inner wall of the first guide sleeve 30. The first guide sleeve 30 limits their movement in the vertical direction, avoids the horizontal deviation or shaking of the positioning member during the rising process, enables the positioning member to gradually approach the battery tray in a stable posture, and ensures that the positioning part of the positioning member can be accurately aligned with the positioning hole or other positioning structure of the battery tray, thereby avoiding the problem of inaccurate positioning due to the deviation of the positioning member.

[0048] When the driving cylinder drives the positioning member to descend, the positioning member and the piston rod 12 move downward along the inner wall of the first guide sleeve 30 again. The first guide sleeve 30 also limits their movement direction, ensures that the positioning member can stably descend, and smoothly separates from the battery tray.

[0049] Therefore, the first guide sleeve 30 provides an accurate guide path for the lifting movement of the positioning member and the piston rod 12. By limiting their movement in the vertical direction, the accuracy of the positioning member during the positioning process with the battery tray is ensured, so that the positioning part can accurately cooperate with the positioning structure of the battery tray, thereby effectively improving the positioning accuracy.

[0050] It should be noted that when the positioning member deviates from the positioning structure of the battery tray during the rising process, part of the force acting on the positioning part of the battery tray will be transmitted to the first guide sleeve 30 outside the positioning member. Since the first guide sleeve 30 is connected to the cylinder body through the mounting seat 31, the mounting seat 31 can transmit and disperse the force to the cylinder body, thereby avoiding damage to the first guide sleeve 30 when it is subjected to excessive force, thereby ensuring the accuracy of the positioning member during repeated positioning.

[0051] As a preferred technical solution of the present application, the bottom of the mounting seat 31 has an abutting surface, and the abutting surface abuts against the cylinder body. The mounting seat 31 is provided with a communication port, and the communication port is penetrated by the abutting surface to the first guide sleeve 30. In addition, the power output end 11 extends into the first guide sleeve 30 through the communication port.

[0052] Therefore, by abutting the abutting surface at the bottom of the mounting seat 31 against the cylinder body, a stable support point is provided for the entire guide assembly, thereby ensuring the stability of the first guide sleeve 30 during the lifting process of the positioning member. When the positioning member deviates from the positioning structure of the battery tray during the positioning process, the force is transmitted from the positioning member to the first guide sleeve 30, and then uniformly transmitted to the cylinder body through the abutting surface of the mounting seat 31, thereby ensuring that the force can be dispersed by the cylinder body, and avoiding damage to the first guide sleeve 30 due to excessive force.

[0053] As a preferred technical solution of the present application, reference is made to Figure 2 and Figure 3The first connecting part includes a connecting column 20, and the second connecting part includes a connecting groove 13 arranged at the top end of the piston rod 12. The connecting column 20 is inserted into the connecting groove 13.

[0054] Based on the structure, when the positioning mechanism is assembled, first, the connecting column 20 of the positioning member is aligned with the connecting groove 13 at the top end of the piston rod 12 and is inserted until the connecting column 20 is fully inserted in place. When the piston rod 12 is extended outward, because the connecting column 20 is inserted into the connecting groove 13, the piston rod 12 exerts a force on the connecting column 20 through the connecting groove 13, thereby driving the positioning member to rise together.

[0055] Therefore, by inserting the connecting column 20 into the connecting groove 13, the piston rod 12 can effectively transmit the driving force to the positioning member. In the process of positioning the battery, the positioning member needs to be accurately raised and lowered to complete the positioning and disengagement of the battery tray. This tightly inserted connection ensures that the extension and retraction movement of the piston rod 12 can be accurately converted into the lifting movement of the positioning member, ensuring the timeliness and accuracy of the positioning action, thereby meeting the high-precision requirements of the battery tray positioning in the battery production process.

[0056] The size and shape of the connecting column 20 are adapted to the connecting groove 13 to ensure accurate insertion. Moreover, the connecting column 20 and the connecting groove 13 are clearance fit, so when the positioning member is worn, damaged, or needs to be adjusted for accuracy, the operator can relatively easily pull the connecting column 20 out of the connecting groove 13, thereby disassembling the positioning member for maintenance or replacement, without the need to disassemble and reassemble the entire driving assembly 10, greatly reducing the maintenance cost and downtime of the equipment and improving the production efficiency.

[0057] In addition, the first connecting part can also be a buckle arranged at the bottom of the positioning member. The second connecting part is a card slot or a boss with a matching buckle at the top end of the piston rod 12. During installation, the buckle of the positioning member is aligned with the card slot or the boss at the top end of the piston rod 12, and the buckle is inserted into the card slot or matched with the boss by applying a certain pressure to complete the connection. During the driving of the positioning member by the driving cylinder, the buckle and the card slot or the boss can stably transmit power. When disassembly is needed, the buckle is pressed or pried to separate it from the card slot or the boss, thereby separating the two connecting parts.

[0058] Of course, the first connecting part can also be a connecting column 20 with external threads, and the second connecting part is a connecting hole with internal threads arranged at the top end of the piston rod 12. During installation, the connecting column 20 with external threads of the positioning member is screwed into the connecting hole with internal threads at the top end of the piston rod 12, and the tightness of the connection is adjusted by rotating. When the driving cylinder drives the positioning member to rise and fall, the threaded connection can effectively transmit power. When disassembly is needed, the connecting column 20 is rotated in the opposite direction to be withdrawn from the connecting hole.

[0059] As a preferred technical solution of the present application, the positioning part comprises a positioning column 21, and the positioning column 21 is connected to the upper end of the connecting column 20, wherein the positioning column 21 is used for being inserted into the positioning hole of the battery cell tray to position the battery cell tray.

[0060] On the basis of this structure, when the battery cell tray is positioned, the driving cylinder is started, the piston rod 12 is extended, and the connecting column 20 and the positioning column 21 are driven to rise together. When the positioning column 21 is completely inserted into the positioning hole, the driving cylinder stops working, and at this time, the close fit of the positioning column 21 with the positioning hole makes the battery cell tray be accurately fixed at the predetermined position, thereby providing a stable positioning basis for subsequent production operations.

[0061] After the relevant operation on the battery cell tray is completed, the driving cylinder is reversely driven, the piston rod 12 is retracted, the positioning column 21 is pulled out of the positioning hole, and returns to the initial position, waiting for the next positioning operation.

[0062] Therefore, by inserting the positioning column 21 into the positioning hole of the battery cell tray, the displacement of the battery cell tray can be limited in the horizontal direction and to a certain extent in the vertical direction, the position accuracy of the battery cell tray in the production process is ensured, the subsequent production process can accurately act on the battery cell on the battery cell tray, and the product quality and consistency are improved.

[0063] Compared with manual positioning or other complex positioning methods, the positioning column 21 in the form of insertion can quickly realize the positioning of the battery cell tray, reduce the positioning time, improve the production efficiency, and especially on a large-scale automatic production line, the production cycle of a single battery can be effectively shortened.

[0064] As a preferred technical solution of the present application, the outer diameter of the positioning column 21 gradually decreases from one end close to the connecting column 20 to one end away from the connecting column 20, so that a guide slope 22 is formed on the outer periphery of the positioning column 21, wherein the guide slope 22 is used for guiding the connection of the positioning column 21 with the positioning hole.

[0065] On the basis of this structure, when the driving cylinder is started to extend the piston rod 12 to drive the positioning column 21 to rise, the guide slope 22 of the positioning column 21 first contacts the edge of the positioning hole. With the further rising of the positioning column 21, the guide slope 22 will slide along the inner wall of the positioning hole to guide the positioning column 21 into the positioning hole.

[0066] In this process, even if there is a certain initial position deviation between the positioning column 21 and the positioning hole, the guide slope 22 can gradually guide the positioning column 21 into the positioning hole, so that the positioning column 21 automatically adjusts the position and gradually realizes more accurate alignment and insertion.

[0067] Therefore, the guide slope 22 can automatically compensate for a certain positional deviation when the positioning column 21 is inserted into the positioning hole, making it easier for the positioning column 21 to accurately enter the positioning hole and improving the accuracy and success rate of positioning. Even if there is a certain deviation or wobble in the initial position, the guide slope 22 can guide the positioning column 21 to the correct position through contact and sliding with the edge of the positioning hole, ensuring the accuracy of each positioning, thereby ensuring the positional accuracy of the battery cell tray during the production process, which is beneficial to improving the quality and consistency of battery production.

[0068] In addition, on the production line, quickly and accurately completing the positioning of the battery cell tray is crucial to improving production efficiency. The presence of the guide slope 22 makes the process of inserting the positioning column 21 into the positioning hole smoother and faster, reducing the time spent due to alignment difficulties, thereby shortening the positioning time of individual battery cell trays and improving the assembly efficiency of the production line as a whole, which helps to realize large-scale automated production.

[0069] As a preferred technical solution of the present application, referring to Figure 2 and Figure 3 , a connecting step 23 is provided between the positioning column 21 and the connecting column 20, and the outer diameter of the connecting step 23 is greater than the outer diameter of the positioning column 21 and the connecting column 20, wherein the lower end surface of the connecting step 23 abuts against the top end of the power output end 11.

[0070] On the basis of this structure, when the driving assembly 10 is started to make the power output end 11 rise, the power output end 11 transmits force to the positioning column 21 through the connecting step 23 and the connecting column 20, driving the positioning column 21 to rise together. During the rising process, the positioning column 21 gradually approaches the positioning hole of the battery cell tray. Since the outer diameter of the connecting step 23 is larger, the abutting area of its lower end surface with the top end of the power output end 11 is larger, which can more stably transmit power and make the rising process of the positioning column 21 more stable.

[0071] Therefore, the provision of the connecting step 23 increases the connection area between the positioning member and the power output end 11, making the connection between them more stable. Compared with direct connection, the connecting step 23 can disperse the stress borne by the connection site, reducing the risk of component damage or loose connection caused by local stress concentration, thereby improving the reliability and stability of the entire connection structure and ensuring that the positioning column 21 can accurately transmit power and perform positioning operations during long-term use.

[0072] In addition, the positioning member as a whole is made of materials such as tungsten-cobalt-based hard alloys, ceramic materials, and diamonds that have wear-resistant and high-hardness properties, which can prolong the service life of the positioning member and maintain its high-precision positioning.

[0073] As a preferred technical solution of the present application, a second guide sleeve 32 is arranged between the connecting step 23 and the first guide sleeve 30, referring to Figure 4 , and the second guide sleeve 32 is used to guide the lifting of the connecting step 23.

[0074] On the basis of this structure, when the driving assembly 10 starts to work, the power output end 11 pushes the positioning member to rise or fall, and the connecting step 23 moves upward or downward accordingly. At this time, the second guide sleeve 32 starts to play a guiding role. The outer periphery of the connecting step 23 is in close contact with the inner wall of the second guide sleeve 32, and under the limitation of the second guide sleeve 32, the connecting step 23 can only move vertically upward and downward.

[0075] Therefore, the second guide sleeve 32 provides a precise vertical movement path for the connecting step 23 through close cooperation with the outer periphery of the connecting step 23, ensuring that the connecting step 23 can only move vertically during the rising and falling process. This precise guidance is crucial for the accurate docking of the positioning column 21 and the positioning hole of the battery tray, effectively improving the positioning accuracy and avoiding the situation that the positioning column 21 cannot be inserted into the positioning hole or is not accurately inserted due to the movement deviation of the connecting step 23.

[0076] It should be noted that when the second guide sleeve 32 guides the connecting step 23, the first guide sleeve 30 is arranged on the outer periphery of the second guide sleeve 32 and cooperates with the mounting seat 31 to form a limiting installation effect on the second guide sleeve 32, ensuring that the second guide sleeve 32 is located in the correct position and guiding the positioning member to rise and fall accurately and stably.

[0077] As a preferred technical solution of the present application, the top end of the first guide sleeve 30 is provided with an abutting step 33, and the abutting step 33 is used to abut against the upper end surface of the connecting step 23 to limit the movement stroke of the positioning member.

[0078] On the basis of this structure, when the driving assembly 10 starts to work, the power output end 11 pushes the positioning member to rise, and the connecting step 23 moves upward accordingly. Under the guidance of the second guide sleeve 32, the positioning member stably rises along the vertical direction. In this process, the connecting step 23 gradually approaches the abutting step 33 at the top end of the first guide sleeve 30.

[0079] When the upper end surface of the connecting step 23 contacts the abutting step 33, the upward movement of the positioning member is limited. At this time, the positioning member reaches the preset maximum upward stroke, and this process ensures that the positioning member will not cause damage to the battery tray or other components due to excessive upward movement. For example, in the operation of inserting the positioning column 21 into the positioning hole of the battery tray, the depth of insertion of the positioning column 21 can be accurately controlled in this way, avoiding damage to the structure of the battery tray due to excessive insertion.

[0080] When the positioning member reaches the maximum upward stroke, the positioning column 21 has just completed the positioning operation on the battery cell tray. At this time, the abutting relationship between the abutting step 33 and the connecting step 23 keeps the positioning member stable in the vertical direction, so that the battery cell tray can perform subsequent production processes in a state of accurate positioning.

[0081] Therefore, by abutting the abutting step 33 and the connecting step 23, the maximum upward position of the positioning member can be accurately budgeted, so as to ensure that the positioning column 21 can be inserted into the positioning hole of the battery cell tray with a suitable depth, or accurately cooperate with the positioning structure of the battery cell tray. This precise control helps to improve the quality and consistency of battery production, and avoids positioning errors or damage to equipment due to inaccurate positioning member stroke.

[0082] In addition, limiting the movement stroke of the positioning member can effectively protect the safety of the equipment and products. If the positioning member rises excessively, it may cause excessive extrusion or damage to the battery cell tray, and even affect other equipment components related to the battery cell tray. The arrangement of the abutting step 33 can prevent such situations from occurring, ensure that the positioning operation is performed within a safe range, prolong the service life of the equipment, and at the same time protect the integrity of the battery cell tray and the battery cell and other products, and reduce the defective rate of the products.

[0083] The technical means disclosed in the application scheme is not limited to the technical means disclosed in the above-mentioned embodiments, but also includes technical solutions composed of any combination of the above technical features. It should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which are also considered within the scope of protection of the present application.
