Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery cover plate adhesive application equipment, and in particular to an L-shaped cover plate connecting piece adhesive application equipment. Background Technology

[0002] For leaded cover plates, the production process involves applying adhesive to connecting pieces. The leads are L-type, and the integrated adhesive sheet 8 needs to be bent and attached to the sides and bottom of the connecting pieces on the cover plate 7. Manual adhesive application is extremely slow and prone to generating air bubbles. Moreover, the processing efficiency is relatively low.

[0003] Therefore, this utility model proposes a bendable adhesive application device. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an L-shaped cover plate connecting piece adhesive application device.

[0005] This utility model proposes an L-shaped cover plate connecting piece adhesive application device for applying adhesive to a cover plate. Unlike the prior art, it includes a mounting frame with a bottom adsorption part mounted on the mounting frame. A side adsorption part is rotatably mounted on the bottom adsorption part. A rotating mechanism is provided between the mounting frame and the side adsorption part. The rotating mechanism is used to drive the side adsorption part to rotate so that the side adsorption part is in a horizontal position or an adhesive application position.

[0006] When the side adsorption part is in a horizontal position, the adsorption surfaces of the side adsorption part and the bottom adsorption part are on the same horizontal plane and are used to adsorb the film;

[0007] When the side adsorption part is in the adhesive application station, the side adsorption part is located above the bottom adsorption part, and the angle between the adsorption surface of the side adsorption part and the adsorption surface of the bottom adsorption part is an acute angle. That is, when the adhesive sheet of the bottom adsorption part contacts the connecting piece of the cover plate, the adhesive sheet adsorbed by the side adsorption part does not contact the connecting piece of the cover plate.

[0008] The side adsorption part has a movable space on the side near the bottom adsorption part. A scraper plate is installed on the mounting frame via a lifting component. The lifting component drives the scraper plate to move upward so as to adhere the film on the side adsorption part to the connecting piece of the cover plate and smooth it out.

[0009] As a further optimization of this utility model, the side adsorption part and the bottom adsorption part adsorb the film placed on the placement plate. The placement plate includes a first placement part and a second placement part, which are connected by a vertical connecting part. The upper surface of the first placement part is lower than the upper surface of the second placement part. The bottom adsorption part adsorbs the film portion above the second placement part, and the side adsorption part adsorbs the film portion on the first placement part.

[0010] As a further optimization of this utility model, the bottom adsorption part has a bottom adsorption hole, the bottom adsorption part has a bottom adsorption channel communicating with the bottom adsorption hole, the adsorption surface of the bottom adsorption part has a bottom breathable pad, and the bottom breathable pad covers the bottom adsorption hole.

[0011] As a further optimization of this utility model, the side adsorption part includes a first support frame and a second support frame, and the first support frame and the second support frame are connected to the bottom adsorption part through the rotating mechanism;

[0012] An active space is formed between the first support frame and the second support frame. The scraper plate is located in the active space, and the lifting component drives the scraper plate to move upward in the active space to smooth the film on the connecting piece of the cover plate, so that the film opposite to the active space is pasted on the connecting piece of the cover plate.

[0013] As a further optimization of this utility model, a clamping frame is mounted on the mounting bracket via a first telescopic member. The clamping frame is located within the movable space and has a clamping bottom surface and a clamping side surface that are perpendicular to each other for clamping the film. The first telescopic member drives the clamping frame to move horizontally so that the bottom and side of the film at the corner are clamped to the connecting piece of the cover plate. During the movement of the mounting bracket, the clamping frame can smooth out the connecting film.

[0014] As a further optimization of this utility model, the scraper plate is installed on the lifting end of the lifting component via a connecting rod, the scraper plate is slidably installed on the connecting rod laterally, and there is an elastic element between the scraper plate and the connecting rod;

[0015] The scraper plate has a smoothing station and a non-contact station. When the scraper plate is in the smoothing station, the elastic element deforms, and the scraper plate contacts the film, pressing the film against the connecting piece of the cover plate. When the scraper plate is in the non-contact station, the elastic element is at its original length, and there is a movable gap between the scraper plate and the film. Even if the mounting frame shakes during the upward movement of the mounting frame, the elastic element on the scraper plate ensures the smoothing effect of the scraper plate on the film.

[0016] As a further optimization of this utility model, the clamping frame has an extension plate. When the first telescopic member drives the clamping frame to move closer to the film, the extension plate presses against the scraper plate, causing the scraper plate to move closer to the film and compress the elastic member. When the elastic member is compressed a certain distance, the clamping frame contacts the film and the corner of the film contacts the corner of the connecting piece of the cover plate.

[0017] To ensure accuracy during the rotation of the side adsorption part relative to the bottom adsorption part, as a further optimization of this utility model, an arc-shaped guide rod is also included, which is mounted on the bottom adsorption part. A guide wheel is mounted on the side adsorption part, and the guide wheel rolls on the arc-shaped guide rod during the rotation of the side adsorption part relative to the bottom adsorption part.

[0018] As a further optimization of this utility model, the side adsorption part is provided with a support roller, the support roller is opposite to the guide wheel, and the arc-shaped guide rod is located between the support roller and the guide wheel. When the side adsorption part rotates relative to the bottom adsorption part, the support roller rolls relative to the arc-shaped guide rod.

[0019] A method for applying adhesive to an L-shaped cover plate connecting piece, using the aforementioned adhesive application equipment, includes the following steps:

[0020] The side adsorption section is in a horizontal position, and then the mounting frame moves the side adsorption section and the bottom adsorption section to the film with the bending part, and the side adsorption section and the bottom adsorption section adsorb the film.

[0021] The rotating mechanism drives the side adsorption part to rotate to the adhesive application station so that the adhesive sheet is in a bent state;

[0022] The mounting bracket moves the side and bottom suction units above the connecting piece of the cover plate, and moves the adhesive film so that the adhesive films corresponding to the suction surfaces of the side and bottom suction units are adhered to the connecting piece of the cover plate.

[0023] The L-shaped cover plate connecting piece adhesive application device proposed in this utility model has a simple structure. The rotating mechanism drives the side adsorption part to rotate, thereby bending the adhesive sheet. Then, the external robotic arm drives the mounting frame to move, so that the bent adhesive sheet is bonded to the connecting piece of the L-shaped cover plate.

[0024] Furthermore, in order to avoid stretching and deforming of the film during the rotation of the side adsorption part driven by the rotating mechanism, preferably, when the side adsorption part is in a horizontal position and has not adsorbed the film, the bottom of the side adsorption part and the bottom of the bottom adsorption part are in the same horizontal plane. At this time, the film to be adsorbed is in a slightly bent state, and the height of the film part opposite to the side adsorption part is slightly lower than the height of the film opposite to the bottom adsorption part.

[0025] Furthermore, in order to further achieve the bonding between the film and the cover plate, a scraper plate and a clamping plate are also provided.

[0026] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] like Figure 2 - Figure 4 The L-shaped cover plate connecting piece adhesive application equipment shown is used for applying adhesive to a mounting frame 1. The mounting frame 1 is fixed with a bottom adsorption part 2 by bolts. A side adsorption part 3 is rotatably mounted on the bottom side adsorption part 3. A rotating mechanism 4 is provided between the side adsorption part 3 and the mounting frame 1. The rotating mechanism 4 is used to drive the side adsorption part 3 to a horizontal position or an adhesive application position.

[0035] When the side adsorption part 3 is in a horizontal position, the adsorption surface of the side adsorption part 3 and the adsorption surface of the bottom adsorption part 2 are on the same horizontal plane and are used to adsorb the film 8.

[0036] When the side adsorption part 3 is in the adhesive application position, the angle between the adsorption surface of the side adsorption part 3 and the adsorption surface of the bottom adsorption part 2 is an acute angle.

[0037] The side adsorption part 3 has a dynamic space 35 on the side near the bottom adsorption part 2. A scraper plate 10 is installed on the mounting frame 1 via a lifting member 11. The lifting member 11 drives the scraper plate 110 to rise and fall so as to smooth and flatten the connecting piece on the cover plate 7 of the side adsorption part 3.

[0038] It should be noted that the mounting frame 1 is connected to an external robotic arm. The robotic arm is used to move the mounting frame 1 in the horizontal plane and raise and lower it in the vertical plane. It is a conventional technique for the external robotic arm to move or rotate the components in the horizontal plane or raise and lower the components in the vertical plane. Therefore, the robotic arm is not shown in the attached drawings.

[0039] The robotic arm is used to move the mounting frame 1 above the film 8 and move the mounting frame 1 downward so that the bottom adsorption part 2 and the side adsorption part 3 adsorb the film 8. Then the robotic arm moves the mounting frame 1 towards the connecting piece near the cover plate 7. Then the rotating mechanism 4 drives the side adsorption part 3 to rotate and puts the side adsorption part 3 in the adhesive application position. During this process, the film 8 is bent.

[0040] The bottom adsorption part 2 has a bottom adsorption hole and a bottom adsorption channel that communicates with the bottom adsorption hole. An external negative pressure tube communicates with the bottom adsorption channel. The negative pressure in the bottom adsorption channel adsorbs the film 8 through the bottom adsorption hole. Preferably, the adsorption surface of the bottom adsorption part 2 has a bottom breathable pad 5. The bottom breathable pad 5 covers the bottom adsorption hole and contacts and adsorbs the film 8, thereby ensuring the uniformity of adsorption of the film 8.

[0041] The side adsorption part 3 has side adsorption holes and side adsorption channels that communicate with the side adsorption holes. The external negative pressure pipe communicates with the side adsorption channels. The negative pressure in the side adsorption channels adsorbs the film 8 through the side adsorption holes. Preferably, the adsorption surface of the side adsorption part 3 has a side breathable pad. The side breathable pad covers the side adsorption holes and contacts and adsorbs the film 8, thereby ensuring the uniformity of adsorption of the film 8.

[0042] When the bottom adsorption part 2 and the side adsorption part 3 do not adsorb the film 8, as in the prior art, the film 8 is placed on the placement plate 9. The placement plate 9 adsorbs the film 8 through negative pressure. To prevent large deformation of the film 8 during bending, such as... Figure 4As shown, in this utility model, preferably, the placement plate 9 has a first placement part 90 and a second placement part 91. The first placement part 90 and the second placement part 91 are connected by a vertical connecting part 92, so that the height of the second placement part 91 is slightly higher than the height of the first placement part 90. The first placement part 90 and the second placement part 91 are connected by a vertical surface, so that the film 8 placed on the placement plate 9 is in a bent state. The bottom adsorption part 2 adsorbs part of the film 8 on the second placement part 91, and the side adsorption part 3 adsorbs part of the film 8 on the first placement part 90. When the side adsorption part 3 is in a horizontal position, there is a gap between the adsorption surface of the side adsorption part 3 and the adsorption surface of the bottom adsorption part 2. The film 8 between the side adsorption part 3 and the bottom adsorption part 2 is in a relaxed state, so as to prevent the film 8 from being pulled when the side adsorption part 3 is rotated to the adhesive application position.

[0043] During the operation, the side adsorption part 3 is in a horizontal position, and then the mounting frame 1 moves the side adsorption part 3 and the bottom adsorption part 2 to the film 8 with the bending part, and the side adsorption part 3 and the bottom adsorption part 2 adsorb the film 8.

[0044] The rotating mechanism 4 drives the side adsorption part 3 to rotate to the adhesive application station so that the adhesive sheet 8 is in a bent state;

[0045] The mounting bracket 1 moves the side adsorption part 3 and the bottom adsorption part 2 to above the connecting piece of the cover plate 7. The mounting bracket 1 moves the film 8 and makes the film 8 corresponding to the adsorption surface of the bottom adsorption part 2 stick to the connecting piece of the cover plate 7. Then the lifting member 11 moves the scraper plate 10 upward so that the film adsorbed by the side adsorption part 3 sticks to the connecting piece of the cover plate 7 and smooths it out.

[0046] like Figure 4 As shown, in some preferred embodiments, the side adsorption part 3 includes a first side frame and a second side frame. The first side frame and the second side frame are both laterally rotatably mounted on the bottom adsorption part 2. The first side frame and the second side frame are both connected to the rotation mechanism 4. The rotation mechanism 4 drives the first side frame and the second side frame to rotate synchronously relative to the bottom adsorption part 2.

[0047] The first side frame includes a first support frame 30 and a first adsorption block 31 connected together, and the first support frame 30 is connected to the bottom adsorption part 2;

[0048] The second side frame includes a connected second support frame 32 and a second adsorption block 33, and the second support frame 32 is connected to the bottom adsorption part 2;

[0049] Both the first adsorption block 31 and the second adsorption block 33 have side adsorption holes and side adsorption channels, and both the first adsorption block 31 and the second adsorption block 33 are provided with side adsorption pads 6, which are used to adsorb the film 8.

[0050] A connecting interval 34 is formed between the first adsorption block 31 and the second adsorption block 33, and an active space 35 is formed between the first support frame 30 and the second support frame 32. The connecting interval 34 is connected to the active space 35.

[0051] A scraper plate 10 is mounted on the mounting frame 1 via a lifting component 11. The scraper plate 10 is located within the movable space 35, and the lifting component 11 moves the scraper plate 10 upward within the movable space 35 to smooth the film 8 attached to the connecting piece of the cover plate 7. The movement of the scraper plate 10 by the lifting component 11 within the movable space 35 achieves adhesion and smoothing of the area below the film 8, and then removes the negative pressure from the side adsorption part 3 and the bottom adsorption part 2. The mounting frame 1 then moves upward under the action of a robotic arm to achieve adhesion and smoothing of the area above the film 8. The lifting component 11 can be an electric cylinder or a pneumatic cylinder as used in the prior art.

[0052] To ensure that the bend of the film 8 fits snugly against the bend of the connecting piece of the cover plate 7, in some embodiments, preferably, a clamping frame 13 is also mounted on the mounting bracket 1 via a first telescopic member 12. The clamping frame 13 is located within the movable space 35 and has a clamping bottom surface and a clamping side surface that are perpendicular to each other for clamping the film 8. The first telescopic member 12 drives the clamping frame 13 to move horizontally, thereby causing the bottom and side of the film 8 at the corner to clamp against the connecting piece of the cover plate 7, and the bend to clamp against the bend of the connecting piece of the cover plate 7. It should be noted that the first telescopic member 12 can be an electric cylinder or a pneumatic cylinder in the prior art.

[0053] During the operation, the side adsorption part 3 is in a horizontal position, and then the mounting frame 1 moves the side adsorption part 3 and the bottom adsorption part 2 to the film 8 with the bending part, and the side adsorption part 3 and the bottom adsorption part 2 adsorb the film 8.

[0054] The side adsorption part 3 is rotated to the adhesive application station so that the adhesive sheet 8 is in a bent state;

[0055] The mounting bracket 1 moves the side adsorption part 3 and the bottom adsorption part 2 to above the connecting piece of the cover plate 7. The mounting bracket 1 moves the film 8 and attaches the film 8 corresponding to the adsorption surface of the bottom adsorption part 2 to the connecting piece of the cover plate 7.

[0056] Then the first telescopic component 12 drives the clamping frame 13 to move horizontally towards the bend of the connecting piece between the film 8 and the cover plate 7, so that the corner of the connecting piece between the film 8 and the cover plate 7 is tightly attached.

[0057] Then the lifting component 11 drives the scraper plate 10 to move upward, thereby achieving the bonding and smoothing of the film 8 opposite to the active space 35. The film 8 contacts the connecting piece of the cover plate 7 and smooths the film 8.

[0058] Then, the negative pressure on the bottom adsorption part 2 and the side adsorption part 3 is removed, and the robotic arm moves the mounting frame 1 upward to achieve the bonding of the film located outside the active space 35. Smoothing.

[0059] like Figure 5 As shown, in some preferred embodiments, the scraper plate 10 is mounted on the lifting end of the lifting member 11 via a connecting rod 14. The scraper plate 10 is laterally slidably mounted on the connecting rod 14, and there is an elastic element 15 between the scraper plate 10 and the connecting rod 14. The elastic element 15 can be a spring in the prior art. Specifically, there is a sliding post 16 on the side of the connecting rod 14 away from the film 8, and a connecting part 92 is above the scraper plate 10. The connecting part 92 is laterally slidably mounted on the sliding post 16, and the elastic element 15 is sleeved on the sliding post 16. The scraper plate 10 has a leveling position and a non-contact position. When the scraper plate 10 is in the leveling position, the elastic element 15 is compressed, and the scraper plate 10 contacts the film 8 and presses the film 8 against the connecting piece of the cover plate 7. When the scraper plate 10 is in the non-contact position, the elastic element 15 is at its original length, and there is an active gap between the scraper plate 10 and the film 8.

[0060] like Figure 5 As shown, in some embodiments, preferably, the clamping frame 13 has an extension plate 130. When the first telescopic member 12 moves the clamping frame 13 closer to the film 8, the extension plate 130 presses against the scraper plate 10 to move it closer to the film 8, so that the scraper plate 10 contacts and abuts against the film 8, and the elastic member 15 is in a compressed state. After the elastic member 15 is compressed a certain distance, the clamping frame 13 contacts the film 8 and the corner of the film 8 contacts the corner of the connecting piece of the cover plate 7. And when the lifting member 11 moves the scraper plate 10 to the uppermost position, the extension plate 130 can also press against the scraper plate 10, so that even if the robot arm shakes during the vertical movement of the mounting frame 1, the scraper plate 10 can still press against the film 8.

[0061] It should be noted that the rotating mechanism 4 can be a structure that drives the rotating shaft in the prior art, such as... Figure 3 In this preferred embodiment, the rotating mechanism 4 includes a second telescopic member, which can be an electric cylinder or a pneumatic cylinder as in the prior art. The mounting end of the second telescopic member is laterally rotatably mounted on the mounting frame 1. The telescopic end of the second telescopic member is laterally rotatably connected to the side adsorption part 3 through a connecting frame. The axis of rotation of the second telescopic member relative to the mounting frame 1 is parallel to the axis of rotation of the second telescopic member relative to the side adsorption part 3, and the axis of rotation of the second telescopic member relative to the mounting frame 1 is parallel to the axis of rotation of the side adsorption part 3 relative to the bottom adsorption part 2. The extension and retraction of the second telescopic member causes the side adsorption part 3 to rotate laterally relative to the bottom adsorption part 2.

[0062] like Figure 3As shown, when the side adsorption part 3 includes a first side frame and a second side frame, the bottom adsorption part 2 is also provided with an arc-shaped guide rod 17. Guide wheels 18 are installed on both the first side frame and the second side frame. The guide wheels 18 are in contact with the arc-shaped guide rod 17. When the side adsorption part 3 rotates relative to the bottom adsorption part 2, the guide wheels 18 roll on the guide rod, thereby ensuring the accuracy of the axis of rotation between the side adsorption part 3 and the bottom adsorption part 2.

[0063] like Figure 3 As shown, preferably, the arc-shaped guide rod 17 has a portion extending beyond the bottom adsorption part 2, and a support roller 19 is mounted on the side adsorption part 3. Support rollers 19 are rotatably mounted laterally on both the first and second side frames. The support rollers 19 contact the arc-shaped guide rod 17, and the arc-shaped guide rod 17 is located between the guide wheel 18 and the support roller 19. During the rotation of the side adsorption part 3 relative to the bottom adsorption part 2, the support roller 19 and the guide wheel 18 roll on the arc-shaped guide rod 17, thereby ensuring accuracy. Preferably, a guide ring groove is formed on the outer surface of the guide wheel 18, and the arc-shaped guide rod 17 has a portion located within the guide ring groove, further ensuring accuracy.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0065] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0066] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

Moreover, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
