Description

Technical Field

[0001] The utility model relates to the welding technology of lead-acid battery electrode groups, and particularly relates to a welding device for battery electrode plate groups. Background Art

[0002] During the assembly process of lead-acid batteries, it is necessary to weld the electrode columns for the electrode plate groups. The welding of the electrode columns of lead-acid batteries is a key process in the assembly process of lead-acid batteries, which directly affects the quality and performance of the batteries; the firmness of the electrode column welding, no false soldering, no fake soldering, and no lead leakage are important indicators to ensure the battery performance.

[0003] In the patent document with the authorization announcement number CN204277343U, a heating and fusion welding fixture for lead-acid battery electrode groups is disclosed, which includes an intermediate positioning plate and ear positioning plates arranged on both sides of the intermediate positioning plate. The intermediate positioning plate is arranged above the lead-acid battery electrode group and is driven to lift by a lifting positioning device. The ear positioning plates are horizontally flush with the ears of the lead-acid battery electrode group and are driven by a horizontal positioning driving device. An ear positioning structure for positioning the ears of the lead-acid battery electrode group is arranged between the intermediate positioning plate and the ear positioning plates; the ear positioning accuracy of the utility model is higher, and since sawteeth are also arranged on the intermediate positioning plate, the cooperation between the pointed parts of the comb teeth and the tooth grooves of the sawteeth facilitates automatic guiding during shaping and positioning.

[0004] However, there is a height difference between the electrode column positioning groove and the cavity formed by the fixture in this scheme. When the lead liquid flows into the cavity, it first converges in the cavity and then spreads into the electrode column positioning groove. This makes the connection between the electrode column and the fused lead liquid relatively shallow, and more lead liquid is required to firmly weld the electrode column. Summary of the Invention

[0005] The technical problem to be solved by the utility model is that the connection between the electrode column and the fused lead liquid is relatively shallow, so that more lead liquid is required for a firm connection.

[0006] To solve the above technical problems, the present utility model provides a welding device for a battery plate group, which includes a welding mechanism and a positioning rod. The welding mechanism is arranged around the positioning rod. The welding mechanism includes a sorting row comb, which is arranged on both sides of the positioning rod. The sorting row comb can move closer to or away from the positioning rod. Fixing members are arranged at both ends of the sorting row comb, and both ends of the positioning rod are connected to the fixing members. A sliding rod is arranged on the fixing member, and a slider is movably sleeved on the sliding rod. Both ends of the sorting row comb are respectively connected to the slider; a control component is further arranged on the fixing member. The control component is located between the sliders and is connected to the slider on the same side. The slider can be controlled to slide on the sliding rod through the control component; the sorting row comb has a first plane, a second plane and a third plane, and the first plane, the second plane and the third plane are arranged in a stepped manner. A sorting part is arranged on the third plane, and the sorting parts on the sorting row combs on both sides of the positioning rod are arranged oppositely. A welding groove and a pole column positioning groove are formed by the height difference between the second plane and the third plane, and the welding groove communicates with the pole column positioning groove.

[0007] In this solution, the sorting row comb has a first plane, a second plane and a third plane, and the first plane, the second plane and the third plane are arranged in a stepped manner. A welding groove and a pole column positioning groove are formed by the height difference between the second plane and the third plane, and the welding groove communicates with the pole column positioning groove. This enables the lead liquid to directly contact the pole column first during welding, then gradually flow into the welding groove, and finally flow to the pole ear clamped between the comb teeth. Less lead liquid is required for the connection between the pole column and the lead liquid to be stable. Description of the Drawings

[0013] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0014] As Figures 1 to 5As shown in the figure, a welding device for a battery plate group includes a welding mechanism 1 and a positioning rod 2. The welding mechanism 1 is arranged around the positioning rod 2. The welding mechanism includes a sorting row comb 3. The sorting row comb 3 is arranged on both sides of the positioning rod 2. The sorting row comb 3 can move closer to or away from the positioning rod 2. Fixing members 4 are arranged at both ends of the sorting row comb 3. Both ends of the positioning rod 2 are connected to the fixing members 4.

[0015] As Figures 3 to 4 shown, in this embodiment, a sliding rod 5 is arranged on the fixing member 4. A through hole 41 is arranged on the fixing member 4. The sliding rod 5 passes through the through hole 41 and forms a first sliding rod portion 51 and a second sliding rod portion 52 on both sides of the fixing member 4. A slider 6 is movably sleeved on the sliding rod 5. The slider 6 includes a first slider 61 and a second slider 62. The first slider 61 and the second slider 62 are respectively slidably sleeved on the first sliding rod portion 51 and the second sliding rod portion 52. Both ends of the sorting row comb 3 are respectively connected to the first slider 61 and the second slider 62. By sliding the first slider 61 and the second slider 62 on the first sliding rod portion 51 and the second sliding rod portion 52, the sorting row comb 3 on both sides of the positioning rod 2 is driven to move closer to or away from the positioning rod 2.

[0016] In this embodiment, baffles 53 are arranged at the ends of the first sliding rod portion 51 and the second sliding rod portion 52. By the blocking of the baffles 53, the first slider 61 and the second slider 62 will not slide off the first sliding rod portion 51 and the second sliding rod portion 52 when sliding on the first sliding rod portion 51 and the second sliding rod portion 52.

[0017] In this embodiment, a control assembly 7 is further arranged on the fixing member 4. The control assembly 7 is located between the sliders 6. The control assembly 7 includes a connecting member 71, a rotating member 72 and a control member 73. Both the connecting member 71 and the control member 73 are connected to the rotating member 72. A connecting rod 42 is further arranged on the fixing member 4. The rotating member 72 and the control member 73 are rotatably sleeved on the connecting rod 42. A control rod 74 is connected between the control members 73. By driving the control rod 74, the control member 73 is driven to rotate on the connecting rod 42. A connecting plate 8 is further arranged above the fixing member 4. A driving device is connected through the connecting plate 8 to control the horizontal movement and lifting movement of the welding device.

[0018] In this embodiment, the connecting member 71 is in the shape of a U-shaped rod. One end thereof is connected to the slider 6 on the same side, and the other end is hinged to the rotating member 72. The connecting member 71 includes an upper connecting member 711 and a lower connecting member 712. One ends of the upper connecting member 711 and the lower connecting member 712 are respectively connected to the first slider 61 and the second slider 62, and the other ends are hinged to both sides of the rotating member 72. When the control rod 74 is pushed upward, the control member 73 drives the rotating member 72 to rotate on the connecting rod 42. The rotating member 72 drives the upper connecting member 711 to move upward and drives the lower connecting member 712 to move downward, thereby driving the first slider 61 and the second slider 62 to approach the positioning rod 2, and finally driving the sorting comb 3 to approach the positioning rod 2. Conversely, when the control rod 74 is pulled downward, the sorting comb is moved away from the positioning rod 2.

[0019] As Figures 2 to 3 shown, in this embodiment, the sorting comb 3 has a first plane 31, a second plane 32 and a third plane 33. The first plane 31, the second plane 32 and the third plane 33 are arranged in a stepped manner. A sorting portion 34 is provided on the third plane 33. The sorting portions 34 on the sorting comb 3 on both sides of the positioning rod 2 are arranged oppositely. The sorting portion 34 is composed of a plurality of comb teeth 37 arranged at intervals. A pointed head portion 371 is provided at the head of the comb tooth 37. When the sorting comb 3 approaches the positioning rod 2, the pointed head portion 371 approaches the side surface of the positioning rod 2 until the pointed head portion 371 abuts against the side surface of the positioning rod 2. Due to the pointed head design of the pointed head portion 371, the comb teeth 37 can more easily pass through the gaps between the tab ears. Since the positioning rod 2 will fall between the tab ears on both sides, the sorting comb 3 can better sort the tab ears.

[0020] In this embodiment, a welding groove 35 and a pole column positioning groove 36 are formed by the height difference between the second plane 32 and the third plane 33. The welding groove 35 communicates with the pole column positioning groove 36. The pole column positioning groove 36 is semicircular, and the welding groove 35 is trumpet-shaped. When the sorting comb 3 positions the tab ears, the tab ears are located between the comb teeth 37, and the height of the tab ears is less than the depths of the pole column positioning groove 36 and the welding groove 35. When welding, the lead liquid can better immerse the tab ears, so that the tab ears are not damaged and the connection with the pole column is more stable.

[0021] During use, the welding device is pushed above the clamping assembly by the driving device. At this time, the arranging comb 3 is horizontally flush with the bottom of the tab. At this time, the control rod 74 is located above the outer arranging comb 3. Push the control rod 74 above the inner arranging comb 3. During the process, the arranging combs 3 on both sides of the positioning rod 2 approach the positioning rod 2 until the arranging part 34 on the arranging comb 3 abuts against the side surface of the positioning rod 2. The tab is located between the comb teeth 37. Then, place the pole column to be welded into the pole column positioning groove 36. Spray a flame through the spray gun to melt the welding rod into a liquid and fill it into the pole column positioning groove 36 and the welding groove 35 until the pole column positioning groove 36 and the welding groove 35 are filled. At this time, the welding liquid submerges the tab, and a firm connection can be formed after cooling.
