Description

Technical Field

[0001] This utility model relates to the field of new energy batteries, and in particular to an adjustable welding positioning device. Background Technology

[0002] With the rapid development of new energy batteries, research on increasing the total capacity of new energy batteries is a key research project. Currently, the most direct way to increase the total capacity of new energy batteries is usually by welding multiple core packs together.

[0003] In the existing technology, during the manufacturing process of square battery cells, ultrasonic welding of the cell tabs is used to connect multiple cell packs in series to increase the total battery capacity. During the welding process, the welding positioning device for fixing the square cell packs usually uses multiple sets of fixtures of different sizes to fix the cell packs of different sizes. When a batch of cells of different sizes is produced, it is necessary to remake the corresponding welding positioning device to fix and position the cell packs to match the equipment production.

[0004] Because existing welding positioning devices have fixed dimensions, multiple sets of devices need to be manufactured to fix battery cells of different sizes, resulting in low compatibility. Utility Model Content

[0005] This utility model provides an adjustable welding positioning device that solves the problem of low compatibility in the prior art. The technical solution is as follows:

[0006] An adjustable welding positioning device includes: a base plate, a first slide rod, a first limiting plate, a first core package, and a second core package.

[0007] The base plate has a rectangular structure, and first fixing plates are vertically arranged at both ends along its length. First fixing holes are formed on the first fixing plates, and the first sliding rod is slidably disposed within the first fixing holes. Two first limiting plates are provided, vertically spaced apart on the base plate, and each first limiting plate is fixedly connected to one end of the first sliding rod.

[0008] The first core package and the second core package are arranged at intervals between the two first limiting plates. The first core package and the second core package are provided with tabs on the side close to each other. The bottom plate is provided with a limiting groove that matches the tabs.

[0009] Optionally, the base plate includes a first side and a second side that are perpendicular to each other. The first fixing plate is parallel to the first side. The first fixing plate has a first mounting hole. The first side has a second mounting hole that matches the first mounting hole. There are multiple second mounting holes, which are spaced apart along a direction perpendicular to the second side.

[0010] Optionally, it also includes a second sliding rod and a second limiting plate. The base plate is vertically provided with a second fixing plate on both sides along the width direction. The second fixing plate is provided with a second fixing hole. The second sliding rod is slidably provided in the second fixing hole. There are two second limiting plates, which are vertically spaced on the base plate. The second limiting plate is fixedly connected to one end of the second sliding rod.

[0011] Optionally, the second fixing plate is parallel to the second side surface, the second fixing plate is provided with a third mounting hole, and the second side surface is provided with a fourth mounting hole that matches the third mounting hole. There are multiple fourth mounting holes, which are spaced apart along a direction perpendicular to the first side surface.

[0012] Optionally, the first slide bar and the second slide bar are provided with scale bars.

[0013] Optionally, the second fixing plate has a locking groove in the horizontal direction, the locking groove is connected to the second fixing hole, and the second fixing plate has a locking hole perpendicular to the direction of the locking groove, and a locking screw passes through the locking hole.

[0016] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0017] This utility model provides an adjustable welding positioning device. First fixing plates are provided at both ends of a base plate along its length. Through the cooperation of a first sliding rod and a first fixing hole, the first limiting plate moves along the length of the base plate. This causes the two first limiting plates to push a first core package and a second core package towards each other, ultimately allowing the electrode tabs on the first and second core packages to engage with the limiting grooves, thus achieving the welding position. The distance between the two first limiting plates can be adjusted by sliding the first sliding rod in the first fixing hole, thereby accommodating the welding of first and second core packages of different sizes and effectively solving the problem of low compatibility in existing technologies.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the overall structure provided in an embodiment of the present utility model; Figure 2 This is a top view of the overall structure provided in an embodiment of the present utility model; Figure 3 This is a schematic diagram of the first fixing plate structure provided in this embodiment of the utility model; Figure 4 This is a schematic diagram of the second fixing plate structure provided in an embodiment of the present utility model; Figure 5 This is a schematic diagram of the base plate structure provided in an embodiment of this utility model. Figures 1 to 5An adjustable welding positioning device is shown, comprising: a base plate 1, a first sliding rod 21, a first limiting plate 31, a first core package 41, and a second core package 42. The base plate 1 has a rectangular structure, and a first fixing plate 51 is vertically arranged at both ends of the base plate 1 along its length. The first fixing plate 51 has a first fixing hole 511. The first sliding rod 21 is slidably arranged in the first fixing hole 511. Two first limiting plates 31 are provided and vertically spaced on the base plate 1. One end of the first limiting plate 31 is fixedly connected to the first sliding rod 21. The first core package 41 and the second core package 42 are arranged between the two first limiting plates 31. The first core package 41 and the second core package 42 are provided with a tab 6 on one side close to each other. The base plate 1 has a limiting groove 10 that matches the tab 6.

[0027] Exemplarily, in this embodiment of the present invention, the limiting groove 10 can be directly formed on the base plate 1, or a mold can be set on the base plate 1 and the limiting groove 10 can be formed on the mold. The limiting groove 10 on different molds has different shapes and sizes. When welding electrode tabs 6 of different shapes and sizes, the mold can be directly replaced to achieve the purpose of matching the electrode tabs 6 with the limiting groove 10. First fixing plates 51 are set at both ends of the base plate 1 along its length direction. The first fixing plates 51 are fixedly connected to the first side 11. The first fixing plates 51 have first fixing holes 511 facing the length direction of the base plate 1. The first fixing holes 511 provide a guiding function for the first sliding rod 21, so that the sliding rod 21 and the first limiting plate 31 can move along the length direction of the base plate 1 and push the first core package 41 and the second core package 42 closer to each other, so that the electrode tabs 6 move into the limiting groove 10 and to the predetermined welding position, thereby facilitating the welding of the electrode tabs 6 on the first core package 41 and the second core package 42. By setting the first sliding rod 21 and the first limiting plate 31, this device can adapt to first core packages 41 and second core packages 42 of different sizes. Simply pushing the first core package 41 and the second core package 42 to move the electrode tab 6 into the limiting groove 10 completes the positioning process of the core package welding station. Compared to traditional technologies where different positioning fixtures are required for each size of core package, this welding positioning device can adapt to core packages of various sizes, thus improving the device's compatibility.

[0028] Optionally, the base plate 1 includes a first side 11 and a second side 12 that are perpendicular to each other. The first fixing plate 51 is parallel to the first side 11. The first fixing plate 51 is provided with a first mounting hole 512. The first side 11 is provided with a second mounting hole 111 that matches the first mounting hole 512. Multiple second mounting holes 111 are provided and are arranged at intervals along the direction perpendicular to the second side 12.

[0029] For example, in this embodiment of the present invention, a plurality of second mounting holes 111 are provided. By cooperating the first mounting hole 512 with different second mounting holes 111, the force point of the first limiting plate 31 acting on the first core package 41 and the second core package 42 can be adjusted. Since the position of the tab 6 on each core package is different, the tab 6 may not be in the middle position of the core package. By adjusting the position of the first limiting plate 31, the first limiting plate 31 always acts the thrust on the middle position of the core package, thereby more stably pushing the first core package 41 and the second core package 42 closer to each other, thereby improving the stability of the device.

[0030] Optionally, it also includes a second slide rod 22 and a second limiting plate 32. The base plate 1 is vertically provided with a second fixing plate 52 on both sides along the width direction. The second fixing plate 52 is provided with a second fixing hole 521. The second slide rod 22 is slidably provided in the second fixing hole 521. There are two second limiting plates 32, which are vertically spaced on the base plate 1. The second limiting plate 32 is fixedly connected to one end of the second slide rod 22.

[0031] For example, in this embodiment of the present invention, two second limiting plates 32 can be provided on both sides of the first core package 41 and the second core package 42. By providing the sliding rod 22 and the second limiting plates 32, the first core package 41 and the second core package 42 can be clamped and fixed from the width direction of the base plate 1 to prevent the first core package 41 and the second core package 42 from shaking during the welding process and affecting the welding accuracy. By providing this structure, the stability of the device can be further improved.

[0032] Optionally, the second fixing plate 52 is parallel to the second side 12, and the second fixing plate 52 is provided with a third mounting hole 522. The second side 12 is provided with a fourth mounting hole 121 that matches the third mounting hole 522. There are multiple fourth mounting holes 121, which are spaced apart along a direction perpendicular to the first side 11.

[0033] For example, in this embodiment of the present invention, by providing the third mounting hole 522 and the fourth mounting hole 121, the second fixing plate 52 can be fixed at different positions along the length of the base plate. When clamping and fixing the first core package 41 and the second core package 42 of different sizes, the position of the second limiting plate 32 can be adjusted to clamp the sides of the first core package 41 and the second core package 42, which can make the second limiting plate 32 clamp and fix the core package more stably, and further improve the stability of the device.

[0034] Optionally, scale bars 7 are provided on the first slide bar 21 and the second slide bar 22.

[0035] For example, in this embodiment of the present invention, by setting the scale bar 7, the positions of the first limiting plate 31 and the second limiting plate 32 can be accurately measured. Thus, when welding a batch of core packages of the same size, the first limiting plate 31 and the second limiting plate 32 can be directly adjusted to the accurate position based on past experience, eliminating the process of slowly pushing the first limiting plate 31 and the second limiting plate 32 toward the core package, thereby saving operation time and improving the clamping efficiency of the device.

[0036] Optionally, the second fixing plate 52 has a locking groove 523 in the horizontal direction, the locking groove 523 is connected to the second fixing hole 521, and the second fixing plate 52 has a locking hole 524 perpendicular to the direction of the locking groove 523, and a locking screw 525 passes through the locking hole 524.

[0037] For example, in this embodiment of the present invention, the same locking groove 523, locking hole 524, and locking screw 525 structure can also be provided on the first fixing plate 51. Figure 4 As shown, taking the second fixed plate 52 as an example, after the position of the second sliding rod 22 is adjusted, in order to prevent the position of the second limiting plate 32 from changing due to external forces, a locking groove 523, a locking hole 524, and a locking screw 525 are provided. The locking screw 525 is inserted into the locking hole 524 and tightened, thereby causing the locking groove 523 to be subjected to force and reducing the groove width, thus increasing the friction between the second fixed hole 521 and the second sliding rod 22. This fixes the relative position of the second fixed hole 521 and the second sliding rod 22, thereby fixing the second fixed plate 52. By setting this structure, the stability of this device is further improved.

[0038] Optionally, a first limiting block 81 is provided between the first core package 41 and the second core package 42, and the two ends of the first limiting block 81 abut against the sides of the first core package 41 and the second core package 42, respectively.

[0039] For example, in this embodiment of the present invention, a first limiting block 81 can be set according to the position of the limiting groove 10 on the base plate 1. By setting the first limiting block 81, the first core package 41 and the second core package 42 can be abutted by the two ends of the first limiting block 81, thereby limiting the position of the first core package 41 and the second core package 42, preventing the position of the first core package 41 and the second core package 42 from being misaligned due to excessive pushing of the first limiting plate 31 and the second limiting plate 32, reducing the time of additional operation, and further improving the clamping efficiency of the device.

[0040] Optionally, two second limiting blocks 82 are provided between the first core package 41 and the second core package 42, and the second limiting blocks 82 are located on both sides of the first limiting block 81 along the width direction of the base plate 1.

[0041] For example, in this embodiment of the present invention, by setting a second limiting block 82, it is possible to prevent the first core package 41 and the second core package 42 from rotating and misaligning due to uneven force when they come into contact with the first limiting block 81. The second limiting block 82 can provide auxiliary support for the first limiting block 81 to receive the force, thereby making the first core package 41 and the second core package 42 more stably clamped and fixed on the welding station, thus further improving the stability of the device.
