Description

A curved suction cup positioning and mounting device for aerogel heat insulation pads used in new energy batteries Technical Field

[0001] This invention relates to the technical field of aerogel heat insulation pad processing equipment, specifically to a curved suction cup positioning and framing device for aerogel heat insulation pads used in new energy batteries. Background Technology

[0002] In known technologies, aerogel heat insulation pads are used between power battery cells to prevent heat transfer between them, thus preventing the fire caused by one cell failure from spreading to other cells. Simultaneously, the aerogel heat insulation pads possess certain compression resilience, providing cushioning to accommodate the expansion and contraction stress of the cells during battery charging and discharging. Aerogel heat insulation pads typically use glass fiber or ceramic fiber as a carrier, and are formed through processes such as immersing liquid gel in the carrier and supercritical drying to achieve a certain level of heat insulation and compressibility. However, because aerogel is brittle, it is prone to chipping and breakage during manual framing (where aerogel is directly placed into a silicone frame by hand), and may even fail to fit into the frame at all, severely impacting the yield and production capacity of the heat insulation pads.

[0003] Meanwhile, the manual framing process is not only inefficient and has a low product yield, but it also easily generates dust during use. The reason for the dust is that the aerogel material is fragile and will cause collisions and friction during the assembly process, which will cause the aerogel to break and generate aerogel dust, affecting health and the cleanliness of the battery workshop, and ultimately affecting the production cost of lithium batteries. Summary of the Invention

[0004] To address the technical problems existing in the prior art, the purpose of this invention is to provide a curved suction cup positioning and framing device for aerogel heat insulation pads used in new energy batteries. This device solves the problems of low production efficiency, low product yield, dust dispersion during manual aerogel framing, which affects health, cleanliness of the battery workshop, and manufacturing costs of lithium batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning and framing device for a curved suction cup of aerogel heat insulation pad for new energy batteries includes a framing base plate, a silicone frame fixing fixture, a middle frame, a silicone frame, a hyperboloid vacuum suction cup, and a pick-and-place robot. The silicone frame fixing fixture is placed on the top surface of the framing base plate by a positioning component, the middle frame is placed on the top surface of the silicone frame fixing fixture by a positioning component, and the silicone frame is placed on the silicone frame fixing fixture. The silicone frame fixing fixture is provided with a vacuum interface, the bottom surface of the silicone frame is in contact with the vacuum interface, and the inner edge of the middle frame is in contact with the outer edge of the silicone frame. The pick-and-place robot is plugged into and connected to the framing base plate by a guide component. The hyperboloid vacuum suction cup includes a flat plate and a vacuum pipe. The top of the flat plate is fixedly connected to the pick-and-place robot. The flat plate is hollow inside and has an opening at the bottom. The vacuum pipe is installed inside the flat plate. The short and long sides of the bottom of the flat plate are both inwardly concave arc-shaped structures.

[0007] As a preferred embodiment, the vacuum pipeline includes an outer rectangular vacuum pipeline frame, an inner rectangular vacuum pipeline frame, a long-side connecting pipe, and a short-side connecting pipe. The outer rectangular vacuum pipeline frame is fixed inside a flat plate. The two ends of the long-side connecting pipe are connected to the midpoints of the two short sides of the outer rectangular vacuum pipeline frame, and the two ends of the short-side connecting pipe are connected to the midpoints of the two long sides of the outer rectangular vacuum pipeline frame, respectively. The midpoints of the two short sides of the inner rectangular vacuum pipeline frame are connected to the long-side connecting pipes, and the midpoints of the two long sides of the inner rectangular vacuum pipeline frame are connected to the short-side connecting pipes, respectively. The inner rectangular vacuum pipeline frame is located inside the outer rectangular vacuum pipeline frame. The outer rectangular vacuum pipeline frame, the inner rectangular vacuum pipeline frame, the long-side connecting pipe, and the short-side connecting pipe are all on the same horizontal plane.

[0008] As a preferred embodiment, the top surface of the silicone frame fixing fixture is provided with a silicone frame vacuum positioning groove. The structure of the silicone frame vacuum positioning groove is the same as that of the silicone frame. The inner edge of the middle frame is flush with the outer edge of the silicone frame vacuum positioning groove. The silicone frame is placed in the silicone frame vacuum positioning groove. The inner wall of the silicone frame vacuum positioning groove fits with the outer edge of the silicone frame. The inner edge of the middle frame fits with the outer edge of the silicone frame. The vacuum interface is located at the bottom of the silicone frame vacuum positioning groove.

[0009] As a preferred embodiment, the positioning component includes two positioning posts, which are vertically fixed to the top surface of the frame base plate and located at both ends of the frame base plate. The silicone frame fixing fixture has first positioning holes at both ends and is fitted onto the two positioning posts through the two first positioning holes. The middle frame has second positioning holes at both ends and is fitted onto the two positioning posts through the two second positioning holes.

[0010] As a preferred embodiment, the guiding component includes two rows of guide posts, which are vertically fixed on both sides of the top surface of the frame base plate. Each row of guide posts includes multiple guide posts evenly spaced along the length of the frame base plate. The two rows of guide posts are arranged in a one-to-one correspondence. The silicone frame has multiple aerogel placement slots, with two corresponding guide posts and one aerogel placement slot corresponding to each other. The silicone frame fixing fixture has two rows of first guide holes on both sides, through which the silicone frame fixing fixture is fitted onto the two rows of guide posts. The middle frame has two rows of second guide holes on both sides, through which the middle frame is fitted onto the two rows of guide posts. The pick-and-place robot has third guide holes at both ends, through which the pick-and-place robot is plugged in and connected to two corresponding guide posts via two third guide holes.

[0011] As a preferred embodiment, the pick-and-place robot includes a connecting rod and two guide sleeves. The connecting rod is vertically fixed to the top of the plate, and the two guide sleeves are fixedly connected to both ends of the plate, respectively. A third guide hole is located in the two guide sleeves, and the two guide sleeves are plugged into and connected to two guide posts in two rows of guide posts through the two third guide holes.

[0012] As a preferred embodiment, the bottom surface of the frame base plate is provided with a second pipe joint, which is connected to the vacuum interface.

[0013] In summary, the present invention has the following advantages:

[0014] 1. The vacuum suction cup of the present invention adopts a double arc surface structure. Due to the vacuum suction, the aerogel is deformed and closely adheres to the surface of the double arc surface suction cup. The aerogel has a reduced length and width on the front projection plane, which increases the assembly gap with the silicone frame. This effectively increases the frame assembly gap by more than 1mm, realizing automated mechanical frame assembly of the aerogel and improving production efficiency and product quality.

[0015] 2. The silicone frame fixing fixture of the present invention uses a silicone frame vacuum positioning groove to position the silicone frame, realizing the positioning of the silicone frame in the front-back and left-right directions, and the vacuum interface realizes the positioning of the silicone frame in the up-down direction, realizing the precise positioning of the silicone frame in the silicone frame fixing fixture, and ensuring the feasibility of aerogel being loaded into the silicone frame.

[0016] 3. The vacuum pick-and-place robot of this invention uses a linear bearing assembly (i.e., the cooperation of guide posts and guide sleeves) for working positioning. The placement error can be controlled within 0.05, which improves the yield and stability of the frame assembly. After the positioning post is inserted, blind placement can be achieved, avoiding the influence of manual release of aerogel and optimizing the operating environment. It not only realizes continuous production and reduces the manufacturing cost of new energy batteries, but also ensures product consistency. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to specific embodiments.

[0028] As shown in Figures 1-9, a curved suction cup positioning and framing device for aerogel heat insulation pads for new energy batteries according to this embodiment includes a framing base plate 1, a silicone frame fixing fixture 2, a middle frame 3, a silicone frame 24, a hyperboloid vacuum suction cup 4, and a picking and placing robot arm 5.

[0029] Frame base plate 1: Its structure is a rectangular plate. The bottom surface of the rectangular plate is provided with a second pipe joint. The second pipe joint passes through the rectangular plate from the bottom and is connected to the vacuum interface of the silicone frame fixing fixture placed on the rectangular plate.

[0030] Two positioning posts 13 are vertically fixed at both ends of the rectangular plate along its length. The fixing method can be interference fit insertion. This embodiment does not limit the fixing method. It can also be screws or welding, depending on the actual production needs.

[0031] In this embodiment, two rows of guide posts 16 are vertically fixed on both sides of the rectangular plate along its width. The fixing method can be interference fit, screws, or welding, depending on actual production needs. Each row contains six guide posts, which are evenly spaced along the length of the rectangular plate, with each row corresponding to the previous one.

[0032] Both the positioning post and the guide post have chamfered tops, which facilitates the insertion of the silicone frame fixing fixture, the middle frame and the guide sleeve. In addition, the positioning of the pick-and-place robot uses a linear bearing assembly (i.e. the cooperation of the guide post and the guide sleeve), and the placement error can be controlled within 0.05, which improves the yield and stability of the frame assembly. After the positioning post is inserted, blind placement can be achieved.

[0033] Silicone frame fixing fixture 2: Its structure is a rectangular plate. The two ends of the rectangular plate along the length direction are respectively provided with first positioning holes 14. When the silicone frame fixing fixture is placed on the mounting base plate, the positioning pins pass through the first positioning holes. That is, the silicone frame fixing fixture is fitted onto the two positioning pins through the two first positioning holes. The two positioning pins restrict the degree of freedom of the silicone frame fixing fixture in the horizontal direction, so that it can only move along the axial direction of the positioning pins.

[0034] The silicone frame fixing fixture has six first guide holes 18 on each side of its width direction. When the silicone frame fixing fixture is placed on the mounting base plate, the twelve guide posts on the mounting base plate pass through the twelve first guide holes. That is, the silicone frame fixing fixture is fitted onto the twelve guide posts through the twelve first guide holes. The guide posts further restrict the degree of freedom of the silicone frame fixing fixture in the horizontal direction, so that it can only move along the axial direction of the positioning post and the guide post.

[0035] The top surface of the silicone frame fixing fixture is provided with a silicone frame vacuum positioning groove 12 that matches the shape and structure of the silicone frame, thereby achieving all-round restriction of the silicone frame in the horizontal direction and preventing the silicone frame from being misplaced by the robotic arm due to deviation in position. The silicone frame fixing fixture is provided with a vacuum interface that runs through the silicone frame fixing fixture from bottom to top. The second pipe connector corresponds to the position of the vacuum interface. When the silicone frame fixing fixture is placed on the frame mounting base plate, the second pipe connector is inserted into the vacuum interface, thereby achieving vertical restriction of the silicone frame and preventing it from moving easily in the vertical direction.

[0036] Middle frame 3: Its structure is a flat plate with a rectangular groove running through the middle of the plate. The inner edge of the rectangular groove and the outer edge of the silicone frame vacuum positioning groove are the same size. When the middle frame is placed on the silicone frame fixing fixture, the inner edge of the rectangular groove and the outer edge of the silicone frame vacuum positioning groove are flush in the vertical direction. When the silicone frame is placed in the silicone frame vacuum positioning groove, the rectangular groove also fits with the outer edge of the silicone frame, further positioning the silicone frame.

[0037] The middle frame has outwardly extending handles along its length, making it easy to remove the middle frame from the positioning posts and guide posts.

[0038] The middle frame has two second positioning holes 15 at both ends along its length. When the middle frame is placed on the silicone frame fixing fixture, the positioning pins pass through the second positioning holes. That is, the middle frame is fitted onto the two positioning pins through the two second positioning holes. The two positioning pins restrict the middle frame's freedom in the horizontal direction, so that it can only move along the axial direction of the positioning pins.

[0039] The middle frame has six second guide holes 19 on each side of its width direction. When the middle frame is placed on the silicone frame fixing fixture, the twelve guide posts on the frame mounting base plate pass through the twelve second guide holes. That is, the middle frame is fitted onto the twelve guide posts through the twelve second guide holes. The guide posts further restrict the middle frame's freedom in the horizontal direction, so that it can only move along the axial direction of the positioning post and the guide post.

[0040] Hyperboloid vacuum suction cup 4: includes a flat plate 7 and a vacuum pipe. The top of the flat plate is fixedly connected to the pick-and-place robot. The flat plate is hollow inside and has an opening at the bottom. The vacuum pipe is installed inside the flat plate. Both the short and long sides of the bottom of the flat plate are inwardly concave arc-shaped structures. The arc shape of the long side of the bottom of the flat plate is long side arc shape 26, and the arc shape of the short side of the bottom of the flat plate is short side arc shape 27.

[0041] As shown in Figure 7-9, plate 7 has a bottom area that is the same size as or slightly larger than the aerogel. It is a rectangular plate with an inwardly concave arc-shaped structure on its long side of the bottom surface, with a radius of 6150 mm and a distance of 1.5 mm from the apex of the arc to the bottom surface. The short side of the bottom surface also has an inwardly concave arc-shaped structure with a radius of 462 mm and a distance of 1.5 mm from the apex of the arc to the bottom surface. Due to the vacuum suction, the aerogel deforms and adheres tightly to the surface of the double-arc suction cup. The aerogel's dimensions on the forward projection plane are reduced, increasing the assembly gap with the silicone frame. This effectively increases the frame assembly gap by more than 1 mm, thus facilitating frame assembly.

[0042] Vacuum piping: includes an outer rectangular vacuum piping frame 8, an inner rectangular vacuum piping frame 9, a long-side connecting pipe 10, and a short-side connecting pipe 11. The outer rectangular vacuum piping frame is fixed inside the flat plate, mainly through a first pipe joint. The two ends of the long-side connecting pipe are respectively connected (through four-way pipe joints) to the midpoints of the two short sides of the outer rectangular vacuum piping frame, and the two ends of the short-side connecting pipe are respectively connected (through four-way pipe joints) to the midpoints of the two long sides of the outer rectangular vacuum piping frame. The midpoints of the two short sides of the inner rectangular vacuum piping frame are connected to the long-side connecting pipes (through four-way pipe joints), and the midpoints of the two long sides of the inner rectangular vacuum piping frame are connected to the short-side connecting pipes (through four-way pipe joints). The inner rectangular vacuum piping frame is located inside the outer rectangular vacuum piping frame. The outer rectangular vacuum piping frame, the inner rectangular vacuum piping frame, the long-side connecting pipe, and the short-side connecting pipe are all on the same horizontal plane.

[0043] Both the outer rectangular vacuum pipe frame and the inner rectangular vacuum pipe frame are rectangular pipe frames formed by splicing two sets of pipes in sequence. By designing the inner rectangular vacuum pipe frame to be more densely distributed than the outer rectangular vacuum pipe frame, it provides greater suction force. Thus, the suction force of the inner rectangular vacuum pipe frame is greater than that of the outer rectangular vacuum pipe frame. This allows for appropriate bending and deformation of the aerogel in the length and width directions, thereby increasing the assembly gap with the aerogel placement groove, so that the aerogel can be easily placed into the aerogel placement groove.

[0044] In this embodiment, the outer rectangular vacuum pipe frame and the first pipe joint on the pick-and-place robotic arm are connected.

[0045] In this embodiment, all the pipes included in the vacuum pipeline are the same pipes used in existing vacuum suction tubes.

[0046] The robotic arm 5 includes a connecting rod 21 and two guide sleeves 22. The connecting rod is vertically fixed to the top of the plate, and the two guide sleeves are fixedly connected to both ends of the plate. The third guide hole 20 is located in the two guide sleeves, and the two guide sleeves are plugged in and plugged in through the two third guide holes and two guide columns in the two rows of guide columns. The plate is provided with a first pipe joint 23, which is connected to a vacuum pipe. The first pipe joint is connected to an external inflation and suction device, which is a commonly used device for vacuum suction of items.

[0047] Connecting rod 21: Its function is to connect with external automated equipment. It is a round rod that is fixedly connected by a flange and a plate.

[0048] In this embodiment, the silicone frame 24 has the structure of a silicone frame used in the prior art, which is provided with six aerogel placement slots 17, two corresponding guide posts and one aerogel placement slot, the aerogel placement slot is a rectangular slot, the guide posts correspond to the midpoint of the short side of the rectangular slot, and the position of the vacuum interface corresponds to the connecting strip between two adjacent aerogel placement slots. This embodiment does not improve the structure of the silicone frame, and will not be described in detail here.

[0049] Usage process: First, place the silicone frame fixing fixture on the frame mounting base plate, then place the silicone frame on the silicone frame fixing fixture, and then place the middle frame to assist in positioning the silicone frame. Turn on the air inflator connected to the second pipe connector to achieve horizontal and vertical positioning of the silicone frame. Connect the pick-and-place robot to the corresponding automated equipment, turn on the air inflator connected to the first pipe connector, place the hyperboloid vacuum suction cup into the aerogel 25, and start working.

[0050] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
