Description

Technical Field

[0001] The present application relates to the technical field of mechanical equipment, and in particular to a pressing device and a gluing device. Background Art

[0002] The soft-pack battery cell includes a battery body and a sealing edge located around the battery body. To prevent relative movement between the sealing edge and the battery body, the sealing edge needs to be connected to the battery body with tape.

[0003] Traditional gluing mechanisms have high requirements for the positioning of the battery cell body, often requiring positioning accuracy within millimeters. If the positioning accuracy of the battery cell body cannot be achieved, or if there are defects on the surface of the battery cell body itself, the tape will not be reliably applied to the surface of the battery cell body. For example, one end of the tape is bonded to the sealing edge, and the other end is bonded to the top surface of the battery cell body. The predetermined position of the battery cell body is that the top surface is in a horizontal state. When the positioning accuracy is insufficient, causing the top surface of the battery cell body to tilt relative to the horizontal plane, the pressure roller for pressing the tape will not be able to press the tape to the top surface of the battery cell body well, which may cause problems such as bubbles between the tape and the surface of the battery cell body. Summary of the Invention

[0004] In view of this, the main technical problem to be solved by this application is to provide a pressing device and a gluing device, which can reduce the requirements for the shape and / or position accuracy of the product when pressing the flexible part onto the surface of the product.

[0005] To address the aforementioned technical issues, this application employs a technical solution: providing a pressing device comprising a driving member, a connecting assembly, and a pressing member. The pressing member is movably connected to the movable end of the driving member via the connecting assembly. When the pressing member presses the flexible member against the surface of a product, the connecting assembly enables the pressing member to adjust its posture relative to the movable end of the driving member to adaptively match the surface of the product.

[0006] In some embodiments of the present application, the connection assembly includes a connecting member, which is in the form of an elongated plate and elastically deformable when subjected to force in the thickness direction. The connecting member is disposed at the movable end of the driving member and is parallel to the surface of the product. A pressing member is disposed on the connecting member, and the connection point between the pressing member and the connecting member and the movable end is spaced apart along the length of the connecting member.

[0007] In some embodiments of the present application, the number of connection points is at least two, and the two connection points are located on both sides of the mobile terminal.

[0008] In some embodiments of the present application, the connecting assembly includes a first guide member, a second guide member, and an elastic member. The first guide member is disposed on the connecting member, with the first guide member's position on the connecting member forming a connection point. The second guide member is disposed on the pressure member and slides with the first guide member along the thickness direction of the connecting member. The elastic member is configured to apply a pair of elastic forces in opposite directions to the connecting member and the pressure member along the sliding engagement direction of the first and second guide members.

[0009] In some embodiments of the present application, the driving member is used to drive the pressing member to move in a direction parallel to the surface of the product so as to gradually press the flexible member against the surface of the product, or the driving member is used to drive the pressing member to approach the surface of the product so as to press the flexible member against the surface of the product.

[0010] In some embodiments of the present application, the pressing member is a pressing roller, which is rotatable around its own axis and is used to roll the flexible member while moving in a direction parallel to the surface of the product.

[0011] In some embodiments of the present application, the pressing member is used to grab the flexible member and, driven by the driving member, press the grabbed flexible member against the surface of the product.

[0012] In some embodiments of the present application, the pressing member has a plurality of adsorption holes connected to the negative pressure source to vacuum-adsorb the flexible member.

[0013] In order to solve the above technical problems, the present application also provides a glue application device, including a first driving member, a first connecting assembly, a grabbing member, a second driving member, a second connecting assembly and a pressing member. The grabbing member is connected to the movable end of the first driving member through the first connecting assembly and is used to grab the flexible member. The first driving member is used to drive the grabbing member to approach the first surface of the product so that the grabbing member presses the first part of the flexible member it grabs against the first surface. The pressing member is movably connected to the movable end of the second driving member through the second connecting assembly. When the pressing member presses the second part of the flexible member against the second surface of the product, the second connecting assembly enables the pressing member to adjust its posture relative to the movable end of the second driving member to adaptively match the second surface. The second driving member is used to drive the pressing member to move in a direction parallel to the second surface so as to gradually press the second part of the flexible member against the second surface.

[0014] In some embodiments of the present application, when the gripping member presses the flexible member against the first surface, the first connecting component can enable the gripping member to adjust its posture relative to the moving end of the first driving member to adaptively match the first surface.

[0015] The beneficial effects of the present application are as follows: Unlike the prior art, the pressing device in the present application includes a driving member, a connecting assembly, and a pressing member. The pressing member is movably connected to the movable end of the driving member via the connecting assembly. When the pressing member presses the flexible member against the surface of the product, the connecting assembly enables the pressing member to adjust its posture relative to the movable end of the driving member to adaptively match the surface of the product. This reduces the requirements for the shape and / or positional accuracy of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] When pressing a flexible component onto a product surface, high requirements are typically placed on the product's shape and / or positional accuracy. Examples of flexible components include adhesive tape. Examples of products include battery cells. Product positional accuracy refers to the deviation of the surface to be bonded from the intended position after the product is placed. Product shape accuracy refers to the deviation of the surface to be bonded from the intended shape after product manufacturing.

[0032] To reduce the requirements for product shape and / or positional accuracy, the present application provides a pressing device comprising a driving member, a connecting assembly, and a pressing member. The pressing member is movably connected to the movable end of the driving member via the connecting assembly. When the pressing member presses the flexible member against the surface of the product, the connecting assembly enables the pressing member to adjust its posture relative to the movable end of the driving member to adaptively match the surface of the product.

[0033] See also Figures 1 to 4 , Figure 1 This is a schematic structural diagram of a pressing device 300 according to an embodiment of the present application pressing the flexible member 2 against the surface of the product 1. Figures 2 to 4 The surface to be bonded of product 1 is in different states. Figure 1 Right view of .

[0034] In some embodiments, the pressing device 300 includes a driving member 331 , a connecting assembly 338 , and a pressing member 337 .

[0035] The pressure member 337 is movably connected to the movable end 332 of the driving member 331 via a connecting assembly 338. Specifically, in some embodiments, the driving member 331 is a cylinder, and the distal end of the piston rod of the cylinder is the movable end 332. The pressure member 337 is movably mounted on the piston rod of the cylinder via the connecting assembly 338 and moves under the drive of the cylinder.

[0036] The driving member 331 is used to drive the pressing member 337 to move in a direction parallel to the surface of the product 1 to gradually press the flexible member 2 against the surface of the product 1. In the illustrated embodiment, the driving member 331 drives the pressing member 337 to move in the first direction D1 to press the flexible member 2 against the top surface 101 of the product 1.

[0037] When the pressing member 337 presses the flexible member 2 against the surface of the product 1, the connecting assembly 338 enables the pressing member 337 to adjust its posture relative to the movable end 332 of the driving member 331 to adaptively match the surface of the product 1. Specifically, within the first reference plane S1 perpendicular to the top surface 101, the pressing member 337 can swing to different angles relative to the movable end 332 of the driving member 331. Figure 2 As shown, in the first state, the top surface 101 of the product 1 is horizontally arranged, and the pressing surface of the pressing member 337 is parallel to the horizontal plane. Figure 3 As shown, in the second state, the right side of the top surface 101 of the product 1 is higher than the left side, and the pressing member 337 adaptively forms a posture with the right end higher than the left end to press the flexible member 2 against the top surface 101 of the product 1. Figure 4 As shown, in the third state, the left side of the top surface 101 of the product 1 is higher than the right side, and the pressing member 337 adaptively forms a posture with the left end higher than the right end to press the flexible member 2 against the top surface 101 of the product 1. Figure 3 and Figure 4 In the figure, the inclination angle A of the top surface 101 of the product 1 relative to the horizontal plane is exaggerated to facilitate intuitive visualization. In actual production, the inclination angle A is smaller, for example, 0.5°. In some embodiments, the first to third states are three different states formed by placing the product 1 three times. In some embodiments, the first to third states are different states of the top surface 101 of the same product 1 at different positions along the first direction D1.

[0038] In this embodiment, if the surface of the product 1 is not in a predetermined posture (e.g., horizontal), the pressing member 337 can adaptively match the surface of the product 1, thereby evenly applying a pressing force to the flexible member 2 to ensure a pressing effect. As a result, this embodiment can reduce the requirements for the shape and / or position accuracy of the product 1.

[0039] In some embodiments, the pressing member 337 is a pressing roller that is rotatable about its own axis and is used to roll the flexible member 2 during movement parallel to the surface of the product 1. This reduces the resistance of the pressing member 337 relative to the flexible member 2 during movement. In other embodiments, the pressing member 337 is not able to rotate, but has a curved pressing surface that is in line contact with the flexible member 2, thereby reducing the resistance during relative movement.

[0040] The specific structure of the connecting component 338 is described in detail below.

[0041] In some embodiments, the connection assembly 338 includes a connector 333 .

[0042] Connector 333 is in the shape of an elongated plate and can elastically deform when subjected to force in its thickness direction. Specifically, when the first end of connector 333 is fixed and pushed against the second end of connector 333 along its thickness direction, the second end can swing relative to the first end, causing connector 333 to form an arc-shaped plate. When the force is removed, the second end returns to its original position, and connector 333 returns to a flat plate. In some embodiments, connector 333 is made of stainless steel.

[0043] The connecting member 333 is arranged at the movable end 332 of the driving member 331 and is parallel to the surface (top surface 101 ) of the product 1 . This arrangement allows the pressing member 337 to press the flexible member 2 , with the reaction force being in the thickness direction of the connecting member 333 .

[0044] The pressing member 337 is disposed on the connecting member 333, and the connection point between the pressing member 337 and the connecting member 333 is spaced apart from the movable end 332 of the driving member 331 in the longitudinal direction of the connecting member 333. In this arrangement, the reaction force of the pressing force acts on the connection point, which can form a torque, thereby enabling the connecting member 333 to elastically deform.

[0045] When the posture of the surface to be bonded (top surface 101 ) of the product 1 changes, the connecting member 333 can be deformed to varying degrees, thereby enabling the pressing member 337 to adapt to the surface to be bonded of the product 1 .

[0046] In some embodiments, the number of connection points is at least two, and the two connection points are respectively located on both sides of the moving end 332 of the driving member 331 . Figure 1 In the illustrated embodiment, the two connection points are located at both ends of the connecting member 333, and the moving end 332 of the driving member 331 is located in the center of the connecting member 333. The two connection points are equidistant from the moving end 332 of the driving member 331.

[0047] See also Figure 5 , Figure 5This diagram illustrates a first portion 201 of a flexible member 2 attached to a first surface 102 of a product 1 in an application scenario. In some applications, a pressing device 300 is required to press the second portion 202 of the flexible member 2 against the second surface 103 of the product 1. To ensure that the second portion 202 adheres to the rounded corner 104 on the left side of the second surface 103 of the product 1, the pressing device 300 is further improved as follows.

[0048] In some embodiments, the connecting assembly 338 includes a first guide member 334 , a second guide member (not visible in the figure), and an elastic member 335 .

[0049] The first guide member 334 is disposed on the connecting member 333, and the position of the first guide member 334 on the connecting member 333 forms a connection point. The second guide member is disposed on the pressing member 337 and slides with the first guide member 334 along the thickness direction of the connecting member 333. In some embodiments, the first guide member 334 and the second guide member are a guide sleeve and a guide post, respectively.

[0050] The elastic member 335 is configured to exert a pair of oppositely directed elastic forces on the connecting member 333 and the pressing member 337 along the sliding engagement direction between the first guide member 334 and the second guide member. In some embodiments, the elastic member 335 is sleeved over the guide post, elastically pressing against the connecting member 333 and the connecting seat 336 at opposite ends of the connecting member 333 in the thickness direction. The pressing member 337 is mounted on the connecting seat 336.

[0051] See also Figure 6 , Figure 6 FIG. 1 is a schematic diagram of a process in which the pressing device 300 of an embodiment of the present application presses the second portion 202 of the flexible member 2 onto the second surface 103 of the product 1. Figure 6 The following describes the operating process of the pressing device 300. Initially, the bottom of the pressing member 337 is at a first height. This first height is lower than the second surface 103 of the product 1. The driving member 331 drives the pressing member 337 in a first direction D1. After the pressing member 337 contacts the rounded corner 104 of the product 1 (through the flexible member 2), the bottom of the pressing member 337 rises to a second height.

[0052] In this embodiment, the first guide member 334 , the second guide member and the elastic member 335 enable the pressing member 337 to rise while moving along the first direction D1 and maintain a constant pressing force, so that the flexible member 2 can be attached to the rounded corner 104 of the product 1 .

[0053] See also Figure 7 , Figure 7 FIG. 4 is a schematic diagram of a pressing device 400 according to an embodiment of the present application.

[0054] In some embodiments, the pressing device 400 includes a driving member 421 , a connecting component 423 , and a pressing member 424 .

[0055] The pressing member 424 is movably connected to the moving end 422 of the driving member 421 through the connecting assembly 423. The driving member 421 can be a cylinder. The driving member 421 is used to drive the pressing member 424 to approach the surface of the product to press the flexible member against the surface of the product. Figure 7 In the illustrated embodiment, the driving member 421 drives the pressing member 424 to move along a second direction D2. The second direction D2 is perpendicular to the surface of the product. When the pressing member 424 presses the flexible member against the surface of the product, the connecting assembly 423 enables the pressing member 424 to adjust its position relative to the movable end 422 of the driving member 421 to adaptively match the surface of the product. Specifically, within a second reference plane S2 perpendicular to the surface of the product, the pressing member 424 can swing to different angles relative to the movable end 422 of the driving member 421.

[0056] In some embodiments, the pressing member 424 is used to grab the flexible member and, driven by the driving member 421 , press the grabbed flexible member against the surface of the product.

[0057] In some embodiments, the pressing member 424 has a plurality of adsorption holes ( Figure 7 Not shown) to vacuum absorb the flexible parts.

[0058] In some embodiments, the connection component 423 may adopt the structure of the connection component 338 described above, which will not be described in detail here.

[0059] In some embodiments, as Figure 7 As shown, the connecting assembly 423 includes a connecting member 425 and two connecting rods 426. The connecting member 425 is in the shape of an elongated plate and can elastically deform when subjected to force in the thickness direction. The connecting member 425 is disposed at the movable end 422 of the driving member 421 and is parallel to the product surface. The movable end 422 of the driving member 421 is located in the center of the connecting member 425. The two connecting rods 426 are located at each end of the connecting member 425, respectively, and fixedly connect the connecting member 425 to the pressure member 424.

[0060] exist Figure 1 and Figure 7 In the embodiment of the pressing device shown, the pressing member is mainly adapted to change its posture adaptively by an elastic connecting member. In other embodiments, the pressing member may also be connected to the driving end of the driving member via a universal joint, thereby adaptively changing its posture.

[0061] See also Figures 8 to 12 , Figure 8 This is a structural diagram of a glue laminating device 100 according to an embodiment of the present application. Figure 9 yes Figure 8 Side view of Figure 10 yes Figure 8 A top view of Figure 11 yes Figure 8 In the BB section view, Figure 12 yes Figure 8 The schematic diagram of the gluing process of the gluing device 100 is shown.

[0062] In some embodiments, the adhesive laminating device 100 includes a first pressing device 120 and a second pressing device 130. The first pressing device 120 is used to press the first portion 201 of the flexible member 2 against the first surface 102 of the product 1. The second pressing device 130 is used to press the second portion 202 of the flexible member 2 against the second surface 103 of the product 1 after the first portion 201 is attached to the first surface 102.

[0063] Specifically, the first pressing device 120 includes a first driving member 121, a first connecting assembly 123, and a gripping member 124. The gripping member 124 is connected to the movable end of the first driving member 121 via the first connecting assembly 123 and is used to grip the flexible member 2. In some embodiments, the gripping member 124 grips the flexible member 2 through vacuum suction. The first driving member 121 is used to drive the gripping member 124 toward the first surface 102 of the product 1, so that the gripping member 124 presses the first portion 201 of the flexible member 2 it grasps against the first surface 102.

[0064] Specifically, the second pressing device 130 includes a second driving member 131, a second connecting assembly 138, and a pressing member 137. The second connecting assembly 138 includes a connecting member, which is in the shape of an elongated plate and elastically deforms when subjected to force in its thickness direction. The connecting member is disposed at the movable end of the second driving member 131 and is parallel to the second surface 103 of the product 1. The pressing member 137 is movably connected to the movable end of the second driving member 131 via the second connecting assembly 138. The pressing member 137 is disposed on the connecting member, and the connection point between the pressing member 137 and the connecting member is spaced apart from the movable end along the length of the connecting member. When the pressing member 137 presses the second portion 202 of the flexible member 2 against the second surface 103 of the product 1, the second connecting assembly 138 enables the pressing member 137 to adjust its posture relative to the movable end of the second driving member 131 to adaptively match the second surface 103. Within a reference plane perpendicular to the second surface 103, and the reference plane perpendicular to the driving direction of the second driving member 131, the pressing member 137 can swing to different angles relative to the movable end of the second driving member 131. The second driving member 131 is used to drive the pressing member 137 to move in a direction parallel to the second surface 103 to gradually press the second portion 202 of the flexible member 2 against the second surface 103.

[0065] The working process of the glue sticking equipment of this embodiment is as follows:

[0066] The grabbing member 124 grabs the flexible member 2 .

[0067] like Figure 12 As shown in part a, the first driving member 121 drives the grabbing member 124 to move along the third direction D3 , approaching the first surface 102 of the product 1 , and pressing the first portion 201 of the flexible member 2 against the first surface 102 .

[0068] The gripping member 124 releases the flexible member 2 .

[0069] like Figure 12 As shown in part b, the first driving member 121 drives the grabbing member 124 to move in the opposite direction of the third direction D3, so that the grabbing member 124 is away from the product 1.

[0070] like Figure 12 As shown in section c, the pressing member 137 is in a preset position, with the bottom of the pressing member 137 lower than the second surface 103 of the product 1. In some embodiments, a driving member may be provided to drive the pressing member 137 from another position to the preset position. As the gripping member 124 approaches or moves away from the first surface 102, the pressing member 137 is in the other position, avoiding obstruction of the gripping member 124's movement.

[0071] like Figure 12 As shown in part d, the second driving member 131 drives the pressing member 137 to move along the third direction D3 , so that the pressing member 137 presses the second portion 202 of the flexible member 2 against the second surface 103 of the product 1 .

[0072] In some embodiments, when the gripping member 124 presses the flexible member 2 against the first surface 102 , the first connecting component 123 can enable the gripping member 124 to adjust its posture relative to the moving end of the first driving member 121 to adaptively match the first surface 102 .

[0073] In some embodiments, the first pressing device 120 is the pressing device 400 described above. In some embodiments, the second pressing device 130 is the pressing device 300 described above.

[0074] In some embodiments, the gluing device 100 further includes a cutting assembly 110. The cutting assembly 110 is used to cut a predetermined length of the flexible member 2 from the continuous flexible member 2. The first pressing device 120 grabs the cut flexible member 2 and presses the first portion 201 of the flexible member 2 onto the first surface 102 of the product 1.

[0076] The cutting assembly 110 includes a base 111 , a movable base 112 , two rollers 1152 , a conveyor belt 116 , a motor 1151 , a first cylinder 113 , a pair of clamping jaws 114 , a second cylinder 117 , a pair of clamping jaws 118 , a third cylinder 1191 and a cutter 1192 .

[0077] The movable seat 112 is slidably arranged on the base 111. Figure 8 Can move left and right.

[0078] Two rollers 1152 are rotatably disposed at intervals on the base 111. The conveyor belt 116 is wound around the two rollers 1152 and connected to the movable base 112. A motor 1151 is disposed on the base 111 and is used to drive the rollers 1152 to rotate, thereby driving the conveyor belt 116 to move, and further driving the movable base 112 to move.

[0079] The first cylinder 113 is disposed on the movable base 112. A pair of clamping jaws 114 are disposed at the movable end of the first cylinder 113. The first cylinder 113 may be a clamping jaw cylinder. The first cylinder 113 is used to drive the pair of clamping jaws 114 to move closer or apart to clamp or release the flexible member 2.

[0080] The second cylinder 117 is disposed on the base 111. A pair of clamping jaws 118 are disposed at the movable end of the second cylinder 117. The second cylinder 117 may be a clamping jaw cylinder. The second cylinder 117 is used to drive the pair of clamping jaws 118 to move closer or apart to clamp or release the flexible member 2.

[0081] The third cylinder 1191 is disposed on the base 111. The cutter 1192 is disposed at the moving end of the third cylinder 1191 and is used for cutting the flexible member 2.

[0082] Operation: A pair of jaws 114 grip the leading end of the continuous flexible member 2. The movable base 112 moves rightward to a set position. During this process, the pair of jaws 114 drags the continuous flexible member 2, transporting it to the right. The pair of jaws 118 grips the continuous flexible member 2. The first pressing device 120 grasps the flexible member 2 between the pair of jaws 114 and the pair of jaws 118. The third cylinder 1191 drives the cutter 1192 to cut the continuous flexible member 2. The pair of jaws 114 releases the cut flexible member 2.

[0084] In some embodiments, the gluing system 1000 includes a holding component 500 and at least two gluing devices 100 .

[0085] The holding assembly 500 is used to hold the product. In some embodiments, the holding assembly 500 holds the product by vacuum adsorption.

[0086] The two gluing devices 100 are respectively disposed on opposite sides of the holding component 500 and are used to simultaneously stick the flexible member on the product.

[0087] Compared with a one-sided gluing mechanism, the gluing system 1000 of the present application has doubled efficiency.
