Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding, and particularly relates to a transfer tray for ultrasonic welding. Background Art

[0002] The ultrasonic welding technology is widely used in the manufacturing process of various products, especially suitable for the welding of thermoplastic plastics. It can be used for welding metal foils of nickel-metal hydride batteries, lithium batteries, and polymer batteries, as well as the mutual fusion of wires, electronic components, contacts, connectors, etc. In addition, the ultrasonic welding technology is also applicable to metal welding. The ultrasonic welding technology can be used to produce clean, efficient, and firm products, reduce production costs, and ensure product quality.

[0003] For the new energy field, the transfer tray for ultrasonic welding usually includes a special mold for the battery shoulder cover to adapt to battery components of different shapes and sizes, that is, it can adapt to the size of a certain product.

[0004] Currently, for ultrasonic welding, it usually designs corresponding trays for specific products, locks different products on the corresponding trays, and welds the trays on the sliding table in cooperation with the turntable, so that the welding mold does not need to move, improving the stability of ultrasonic welding. A variety of welding molds are integrated on the multi-station turntable.

[0005] In the above operation, since the tray design is only for a single product, it is difficult for different products to adapt to the same tray. Undoubtedly, it is necessary to increase the tray design and research and development for different products, which will increase the production cost of the tray. At the same time, when using the tray, it is also difficult to find a tray suitable for the product. The whole method will increase the feeding steps before ultrasonic welding and affect the selection of the tray for the product. Summary of the Utility Model

[0006] The utility model provides a transfer tray for ultrasonic welding, which is used to solve the problem that different single products only target one kind of tray. If different products need to be produced, different trays need to be designed, increasing the production cost of the trays.

[0007] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A transfer tray for ultrasonic welding includes a bottom plate capable of accommodating a product and a positive pressure member installed on the bottom plate, and further includes a side pressure member installed on the bottom plate, which includes at least one side pressure block pressing on the side of the product; the positive pressure member includes at least one limiting block pressing on the front and back sides of the product.

[0009] In the above solution, the positive pressure member can be provided with limiting blocks on the front side and / or the rear side of the product. Two limiting blocks are used to squeeze the front side or the rear side of the product respectively, and the product is squeezed to the middle of the bottom plate. The side pressure member is the same as the positive pressure member. A single side pressure block can be used to squeeze the side of the product, so that the product leans against the plate provided on the bottom plate. Two side pressure blocks can also be used to squeeze the two sides of the product, so that the product is restricted on the bottom plate. The combination of the side pressure block and the limiting block can adapt to different products.

[0010] Preferably, the positive pressure member further includes a secondary pressure block and a main pressure block that slide along the width direction of the bottom plate. At least one pair of the secondary pressure block and the main pressure block is provided, and the tops of both are connected to the limiting block. Among them, the secondary pressure block and the main pressure block slide relative to each other along the width direction of the bottom plate through a slide rail, so that the limiting blocks on their upper parts press different positions at the top of the product respectively. At the same time, the secondary pressure block and the main pressure block press different positions at the bottom of the product, thereby restricting the product in the width direction along the bottom plate.

[0011] Preferably, the bottom plate is provided with the same number of secondary pressure cylinders and positive pressure cylinders as the secondary pressure block and the main pressure block, and the secondary pressure block and the main pressure block drive the corresponding pair of the secondary pressure block and the main pressure block to move towards each other. It is convenient for the secondary pressure cylinder and the positive pressure cylinder to provide driving force for the secondary pressure block and the main pressure block, so that the secondary pressure block and the main pressure block squeeze and position the front and rear sides of the product.

[0012] Preferably, the side pressure member further includes a squeezing block provided on the side of the product and opposite to the side pressure block, and the side pressure block and the squeezing block can move towards each other along the length direction of the bottom plate. The two sides of the product are squeezed by a side pressure block and a squeezing block, and at the same time, in cooperation with the secondary pressure block and the main pressure block, the product is fixed on the bottom plate.

[0013] Preferably, side pressure cylinders are installed at both ends of the bottom plate, and the output ends of the side pressure cylinders are fixed to the side pressure blocks. The side pressure cylinders provide power for the side pressure blocks, which is convenient for squeezing and positioning the product through the side pressure blocks.

[0014] Preferably, the secondary pressure blocks are arranged on both sides of the main pressure block, and the adjacent two secondary pressure blocks are integrally formed. The squeezing block is fixed to the integrally formed secondary pressure block through the side pressure cylinder. This setting can effectively reduce the component space between adjacent products, simplify the design, and enable a single secondary pressure cylinder to drive the integrally formed negative pressure block to act.

[0015] Preferably, a guide rail is fixedly installed on the main pressure block, and the moving end of the guide rail is fixed to the limiting block connected to its top. The limiting block can move back and forth along the length direction of the bottom plate through the guide rail, and the distance between the two limiting blocks can be adjusted, which is convenient for the limiting blocks to press the product more evenly and helps with the welding of the battery shoulder cover.

[0016] As can be seen from the above technical solutions, the utility model has the following beneficial effects:

[0017] By arranging a positive pressure member and a side pressure member, the positive pressure member further includes a main pressure block and a sub-pressure block distributed on the front and rear surfaces of the product. The main pressure block and the sub-pressure block can press the front and rear surfaces of different products, while the side pressure block and the extrusion block can press the side surfaces of different products, so as to adapt to different combinations of product shapes, reduce the number of trays required, lower the production cost of the trays, and reduce the steps of selecting trays before ultrasonic welding.

[0018] The trays are automatically compatible, and the sliding table cooperates with the rotary table for welding, so that the welding die does not need to move, improving the stability of ultrasonic welding. Multiple welding dies are integrated on the multi-station rotary table, the equipment occupies a small space, and the equipment utilization rate is high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following is a detailed description of a preferred embodiment of the utility model with reference to the accompanying drawings.

[0029] AsFigure 1 and Figure 2 As shown in Figure 2 , a transfer tray for ultrasonic welding includes a bottom plate 10 capable of accommodating a product 40 and a positive pressure member 20 mounted on the bottom plate 10. It further includes a side pressure member 30 mounted on the bottom plate 10, which includes at least one side pressure block 302 that presses against the side of the product 40; the positive pressure member 20 includes at least one limiting block 204 that presses against the front and rear sides of the product 40. Among them, the product 40 is a new energy battery and is square. The bottom plate 10 can be transferred on a sliding table to transfer the product 40 to the ultrasonic welding position, and then the shoulder cover of the product 40 can be welded and formed. Multiple products 40 can be placed on the bottom plate 10. The positive pressure member 20 presses against the front and rear sides of the product 40 to position the product 40 on the bottom plate 10. The side pressure member 30 presses against the two sides of the product 40, and finally fixes the product 40 along the length and width directions of the bottom plate 10. Multiple groups of products 40 are arranged on the bottom plate 10, and corresponding multiple groups of positive pressure members 20 and side pressure members 30 are also arranged on the bottom plate 10.

[0030] Specifically, the positive pressure member 20 can be provided with a limiting block 204 on the front side and / or the rear side of the product 40. If a single limiting block 204 is used, the limiting block 204 presses against the front side or the rear side of the product 40, making the product 40 closely lean against a plate flush with multiple groups of positive pressure members 20 to position the product 40; in addition, preferably two limiting blocks 204 are used, so that the limiting blocks 204 respectively press against the front side or the rear side of the product 40, and the product 40 is squeezed to the middle of the bottom plate 10. The side pressure member 30 is the same as the positive pressure member 20. That is, a single side pressure block 302 can be used to press against the side of the product 40, making the product 40 lean against the plate provided on the bottom plate 10, or two side pressure blocks 302 can be used to press against the two sides of the product 40, making the product 40 located between the two side pressure blocks 302 and the two limiting blocks 204.

[0031] As Figures 1 - 3 shown in Figures 1 - 3 , the positive pressure member 20 further includes a secondary pressure block 203 and a main pressure block 205 that slide along the width direction of the bottom plate 10. At least one pair of secondary pressure block 203 and main pressure block 205 are provided, and the tops of both are connected to the limiting block 204. Among them, the secondary pressure block 203 and the main pressure block 205 slide relative to each other along the width direction of the bottom plate 10 through a slide rail, so that the relatively upper limiting blocks 204 respectively press against different positions at the top of the product 40. At the same time, the secondary pressure block 203 and the main pressure block 205 press against different positions at the bottom of the product 40, thereby restricting the product 40 in the width direction of the bottom plate 10.

[0032] Specifically, the bottom plate 10 is installed with the corresponding number of auxiliary pressing cylinders 201 and main pressing cylinders 202 for the auxiliary pressing blocks 203 and main pressing blocks 205. The auxiliary pressing blocks 203 and main pressing blocks 205 drive a corresponding pair of auxiliary pressing blocks 203 and main pressing blocks 205 to move towards each other. Among them, both the auxiliary pressing cylinders 201 and main pressing cylinders 202 are installed on the bottom plate 10 through the support frame 206. The shaft bodies of the auxiliary pressing cylinders 201 extend out and act on the auxiliary pressing blocks 203, causing the auxiliary pressing blocks 203 to squeeze the front and rear surfaces of the product 40 along the width direction of the bottom plate 10. The shaft bodies of the main pressing cylinders 202 extend out and act on the main pressing blocks 205, causing the main pressing blocks 205 to move along the width direction of the bottom plate 10 and squeeze the front and rear surfaces of the product 40.

[0033] As Figures 1 - 3 shown, the side pressing member 30 further includes a pressing block 303 provided on the side of the product 40 and opposite to the side pressing block 302. The side pressing block 302 and the pressing block 303 can move towards each other along the length direction of the bottom plate 10. Among them, for squeezing the two side surfaces of the product 40, in addition to using the side pressing block 302, one of the side pressing blocks 302 can be replaced with the pressing block 303, that is, the two side surfaces of the product 40 are squeezed by one side pressing block 302 and one pressing block 303, and at the same time, in cooperation with the auxiliary pressing block 203 and the main pressing block 205, the product 40 is fixed on the bottom plate 10.

[0034] Side pressing cylinders 301 are installed at both ends of the bottom plate 10. The output ends of the side pressing cylinders 301 are fixed to the side pressing blocks 302. Among them, the side pressing cylinders 301 are fixed to the bottom plate 10 through the frame body. The shaft bodies of the side pressing cylinders 301 extend out and drive the side pressing blocks 302 to squeeze the sides of the product 40, so that the position of the product 40 is fixed.

[0035] The auxiliary pressing blocks 203 are arranged on both sides of the main pressing block 205, and are integrally formed between adjacent two auxiliary pressing blocks 203. The pressing block 303 is fixed to the integrally formed auxiliary pressing blocks 203 through the side pressing cylinder 301. Among them, for a more concise design of the entire tray, when placing multiple products 40, this application is provided with three groups of products 40, specifically as follows:

[0036] Three groups of products 40 are equidistantly placed on the bottom plate 10. Positive pressure cylinders 202 are arranged on the front and rear sides of each group of products 40. The positive pressure cylinders 202 drive the two opposite main pressure blocks 205 to squeeze the front and rear sides of the products 40. At the same time, auxiliary pressure cylinders 201 are respectively arranged on both sides of the positive pressure cylinders 202. The auxiliary pressure cylinders 201 drive the two opposite auxiliary pressure blocks 203 to move towards each other, jointly squeezing the front and rear sides of the products 40. The auxiliary pressure blocks 203 between two adjacent products 40 are integrally formed, which can further improve the stability of the extrusion force between adjacent products 40. At the same time, it also provides enough space to facilitate the installation of the mounting frame 304 of the driving extrusion block 303 on the integrally formed auxiliary pressure block 203, enabling the integrally formed auxiliary pressure block 203 to move back and forth along the width direction of the bottom plate 10, providing enough space when placing the products 40.

[0037] As Figure 3 and Figure 4 shown, a guide rail 207 is fixedly installed on the main pressure block 205. The moving end of the guide rail 207 is fixed to the limit block 204 connected to its top. Among them, multiple limit blocks 204 can be arranged on the main pressure block 205, preferably two. And to improve the stability of the limit block 204 pressing different products 40, the limit block 204 can move back and forth along the length direction of the bottom plate 10 through the guide rail 207, and the distance between the two limit blocks 204 can be adjusted, facilitating the more uniform pressing of the products 40 by the limit blocks 204, which is helpful for the shoulder cover welding of the battery.

[0038] The limit block 204 is L-shaped. In addition, various other shapes can also be set, such as wedge-shaped, trapezoidal, and isosceles right triangle-shaped.

[0039] As Figure 1 、 Figures 5 - 8 shown, the product 40 is a single battery or a combination of multiple batteries. The specific combination methods are such as a single battery, two or three batteries combined in the same direction, and four groups of batteries combined in a square shape. If it is a single battery, only the auxiliary pressure block 203 and the side pressure block 302 are required to press the product 40, and the remaining pressing methods are the ones mentioned above.

[0040] When producing a certain product 40, the multi-station turntable switches to the corresponding station. There are two trays, two picking and placing positions, and one welding position on the sliding table. When the tray at the welding position has materials, welding is carried out. The tray moves on the sliding table to complete the welding of multiple products 40 in the tray. At the same time, the other tray is picked and loaded by the handling mechanism at the picking and placing position. After the products 40 on the tray at the welding position are welded, the tray at the welding position is moved out to the picking and placing position for picking and loading. The tray after loading is moved into the welding position for welding, and so on in a cyclic manner for production.

[0041] The above-described embodiments are merely descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
