Description

Technical Field

[0001] The invention belongs to the technical field of water cooling plates, in particular to a water cooling plate welding device and a welding method. Background Art

[0002] The water-cooling plate, also known as the cooling plate or liquid cooling plate, is used to cool or heat the power battery (when starting at low temperature, it needs to be heated in reverse). It is a key component to ensure that the power battery operates within the normal temperature range. The water-cooling plate needs to be welded during production.

[0003] The prior art also proposes some solutions for the welding of water-cooled plates. For example, a patent application with the authorization announcement number CN216151583U discloses a welding pallet for a water-cooled plate, including an outer frame, a stainless steel pipe, a steel plate support frame and a positioning block. The outer frame is a regular quadrilateral formed by splicing four groups of L-shaped structures. It not only solves the problem of low product qualification rate caused by inadequate support or poor support flatness; it also solves the problem of serious product deformation caused by slow cooling of the original welding fixture; and solves the problem of difficulty in ensuring support flatness in traditional pallet processing and manufacturing through machining.

[0004] Although the above technical solution solves the serious problem of product deformation caused by slow cooling of the welding fixture, there are still other problems in specific use. For example, there will be slag in the welding process, and the slag is generally cleaned manually by the staff. Moreover, if the slag is placed on the surface of the water-cooled plate, it will affect the molding quality of the water-cooled plate.

[0005] To this end, the present invention provides a water-cooling plate welding device and a welding method. Summary of the invention

[0012] Preferably, a support frame is installed on the surface of one of the cleaning plates, a through groove is opened inside the support frame, and a telescopic through rod is arranged on the surface of the other cleaning plate, a scraping brush plate is arranged on the surface of the telescopic through rod, and a limiting unit is arranged on the surface of the telescopic through rod, and the limiting unit is used to drive the telescopic through rod and the scraping brush plate to move at a certain speed.

[0016] A water-cooling plate welding method, which is applicable to the above-mentioned water-cooling plate welding device, comprises the following steps:

[0017] S1. When the water-cooling plate and the bottom plate are butt-jointed and welded, the water-cooling plate and the bottom plate are placed on the placement plate 1 and the placement plate 2 respectively, and then the driving mechanism is controlled to drive the placement plate 1 and the placement plate 2 to approach each other, so that the butt joint of the side wall of the bottom plate is aligned with the welding groove on the surface of the water-cooling plate, and until the butt joint is completely embedded in the welding groove.

[0023] 3. The water-cooled plate welding device and welding method described in the present invention, after one welding is completed, when the placing plate one and the placing plate two move away from each other, as the telescopic through rod is pulled out from the inside of the through groove, the limit spring on the outer surface of the telescopic through rod will be in a stretched state, and as the telescopic through rod is stretched, the telescopic pressure head on the surface of the telescopic through rod will be pulled out from the inside of the limiting groove, and the limit spring is still in a stretched state. Therefore, under the elastic force of the limit spring, the telescopic through rod will drive the scraper brush plate to reciprocate at a certain speed, and the scraper brush plate will clean the slag at the welding point, avoiding manual cleaning by the staff, and the operation is more convenient.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 4 As shown, a water-cooled plate welding device according to an embodiment of the present invention comprises a workbench 1, a support frame 2 is fixedly installed above the workbench 1, a placement plate 201 and a placement plate 202 are slidably installed above the support frame 2, the placement plate 201 and the placement plate 202 are used to place the water-cooled plate and the bottom plate, a driving mechanism is arranged inside the support frame 2, the driving mechanism is used to drive the placement plate 201 and the placement plate 202 to approach each other, a welding seat 3 is installed on the upper side of the workbench 1 through a side support rod, a welding head 4 is arranged on the surface of the welding seat 3, and a cleaning mechanism is arranged on the outer surfaces of the placement plate 201 and the placement plate 202, and the cleaning mechanism is used to clean the residual debris on the welding part of the surface of the water-cooled plate;

[0036] During operation, when the water-cooling plate and the bottom plate are docked and welded, the water-cooling plate and the bottom plate are placed above the placement plate 1 201 and the placement plate 202 respectively, and then the driving mechanism is controlled to drive the placement plate 1 201 and the placement plate 202 to approach each other, so that the docking joint of the bottom plate side wall is aligned with the welding groove on the surface of the water-cooling plate, and until the docking joint is completely embedded in the welding groove, and then the external controller drives the welding head 4 on the surface of the welding seat 3 to weld the water-cooling plate and the bottom plate. The welding method here is the existing technology and is not described in detail in this embodiment. Through the design of the driving mechanism and the cleaning mechanism, the water-cooling plate and the bottom plate can be completely matched and docked to ensure the subsequent welding effect of the water-cooling plate and the bottom plate, and the welding position before welding and the position after welding can also be cleaned to ensure the molding quality.

[0037] like Figures 2 to 6As shown, the driving mechanism includes a transverse shaft 5 rotatably mounted inside the supporting frame 2, the outer surface of the transverse shaft 5 is fixedly connected with a central gear 6, the end of the transverse shaft 5 is connected to the output end of the motor, the motor is mounted inside the supporting frame 2, the lower end surface of the placement plate 1 201 is fixedly mounted with a supporting frame 1 7, the lower end surface of the supporting frame 1 7 is mounted with a rack 1 8, the lower end surface of the placement plate 2 202 is fixedly mounted with a supporting frame 2 9, the lower end surface of the supporting frame 2 9 is mounted with a rack 2 10, the central gear 6 is meshedly connected with the rack 1 8 and the rack 2 10 respectively, and the center lines of the placement plate 1 201 and the placement plate 2 202 are located on the same axis; it should be noted that, in the embodiment of the present invention, the shape and length of the placement plate 1 201 and the placement plate 2 202 are respectively adapted to the shapes of the water cooling plate and the bottom plate

[0038] During operation, when the water-cooling plate and the bottom plate are placed on the surfaces of the placement plate 1 201 and the placement plate 2 202 respectively, the control motor drives the horizontal axis 5 to rotate, and the horizontal axis 5 drives the central gear 6 to rotate. The central gear 6 will drive the meshing rack 1 8 and the rack 2 10 to move closer to each other, and the rack 1 8 and the rack 2 10 will respectively drive the supporting frame 1 7 and the placement plate 1 201 and the supporting frame 2 9 and the placement plate 2 202 to move closer to each other. Since the center lines of the placement plate 1 201 and the placement plate 2 202 are located on the same axis, the water-cooling plate and the bottom plate will completely fit and dock when the two move against each other, thereby ensuring the subsequent welding effect of the water-cooling plate and the bottom plate, which is beneficial to the subsequent use of the water-cooling plate.

[0039] The surfaces of the placement plate 1 201 and the placement plate 2 202 are both provided with placement grooves, and the placement grooves are used to place the water cooling plate and the bottom plate. The placement grooves are provided to facilitate the subsequent docking of the water cooling plate and the bottom plate.

[0040] A plurality of guide frames 11 are installed above the workbench 1, two guide shafts 12 are installed on the lower end surface of the placement plate 1 201, and two guide shafts 13 are installed on the lower end surface of the placement plate 202. The guide shafts 12 and 13 are respectively slidably installed in the guide frames 11 at different positions, and a circular guide groove compatible with the guide shafts 12 and 13 is provided inside the guide frame 11; during operation, when the placement plate 1 201 and the placement plate 2 202 are close to each other, the placement plate 1 201 and the placement plate 2 202 will respectively drive the guide shafts 12 and 13 on their surfaces to move in the guide frame 11, and under the limit of the guide frame 11, it can be ensured that the placement plate 1 201 and the placement plate 2 202 move on the same axis, which is convenient for the subsequent welding of the water-cooling plate and the bottom plate.

[0041] like Figures 2 to 7As shown, the cleaning mechanism includes L-shaped brackets 14 respectively installed on the side walls of the placement plate 1 201 and the placement plate 2 202, and a cleaning plate 15 is provided on the surface of each L-shaped bracket 14, and bristles are provided on the surface of the cleaning plate 15, and the cleaning plate 15 is arranged at the welding groove of the water cooling plate;

[0042] During operation, when the placement plate 1 201 and the placement plate 2 202 are close to each other, both will drive the cleaning plate 15 to move at the same time. The bristles on the surface of the cleaning plate 15 will clean the welding groove of the water-cooling plate during the synchronous movement, thereby improving the subsequent welding forming rate of the water-cooling plate.

[0043] A support frame 16 is installed on the surface of one of the cleaning plates 15, and a through groove 161 is provided inside the support frame 16. A telescopic through rod 17 is provided on the surface of the other cleaning plate 15, and a scraping brush plate 18 is provided on the surface of the telescopic through rod 17. A limiting unit is provided on the surface of the telescopic through rod 17, and the limiting unit is used to drive the telescopic through rod 17 and the scraping brush plate 18 to move at a certain speed.

[0044] During operation, when the placement plate 1 201 and the placement plate 2 202 are close to each other, the telescopic through rod 17 on the surface of one of the cleaning plates 15 will be inserted into the through groove 161, and then the limiting unit will clamp the telescopic through rod 17 and the scraper brush plate 18 in the through groove 161. When one welding is completed, the central gear 6 is controlled to reverse, so that the central gear 6 drives the rack 1 8 and the rack 2 10 to move away from each other, that is, the placement plate 1 201 and the placement plate 2 202 move away from each other. Since the water-cooled plate and the bottom plate have been welded and are not fixed on the placement plate, the water-cooled plate and the bottom plate will not move when the two move away from each other. Then, under the action of the limiting unit, the telescopic through rod 17 and the scraper brush plate 18 move at a certain speed, so that the scraper brush plate 18 can clean the welded part after welding, so that the slag falls off, thereby avoiding the slag remaining on the surface of the water-cooled plate and affecting the molding quality of the water-cooled plate.

[0045] like Figures 3 to 7As shown, the limiting unit includes a telescopic pressure head 19 installed on the outer surface of the telescopic through rod 17, and a limiting groove 20 is provided at the groove wall of the through groove 161. The shape of the telescopic pressure head 19 is adapted to the shape of the limiting groove 20, and the shape of the telescopic pressure head 19 is an arc shape. The outer surface of the telescopic through rod 17 is sleeved with a limiting spring 21; when working, after the placement plate 1 201 and the placement plate 2 202 are close to each other so that the water-cooling plate and the bottom plate are connected, the telescopic through rod 17 will extend into the inside of the through groove 161, and the telescopic pressure head 19 will be completely embedded in the inside of the limiting groove 20, and the water-cooling plate and the bottom plate are just connected; After one welding is completed, when the placement plate 1 201 and the placement plate 2 202 move away from each other, as the telescopic through rod 17 is pulled out from the inside of the through groove 161, the limit spring 21 on the outer surface of the telescopic through rod 17 will be in a stretched state. As the telescopic through rod 17 is stretched, the telescopic pressure head 19 on the surface of the telescopic through rod 17 will be pulled out from the inside of the limit groove 20. At this time, the limit spring 21 is still in a stretched state. Therefore, under the elastic force of the limit spring 21, the telescopic through rod 17 will drive the scraper brush plate 18 to reciprocate at a certain speed. The scraper brush plate 18 will clean the slag at the welding point, avoiding manual cleaning by the staff, and the operation is more convenient.

[0046] The outer surface of the telescopic pressure head 19 is sleeved with a telescopic spring 22, and the surface of the limiting groove 20 is provided with a rounded corner; the rounded corners of the telescopic spring 22 and the limiting groove 20 can facilitate the telescopic pressure head 19 and the telescopic spring 22 to be slowly pulled out of the limiting groove 20 when the limiting spring 21 is in a stretched state, thereby facilitating the subsequent limiting spring 21 to drive the telescopic through rod 17 to move.

[0047] The scraper brush plate 18 is provided with bristles on its surface, and the bristles are in contact with the surface of the water-cooled plate. Such a design can facilitate the scraper brush plate 18 to clean the welding completed position.

[0048] like Figure 8 As shown, a water-cooling plate welding method, which is applicable to the water-cooling plate welding device described above, comprises the following steps:

[0049] S1. When the water-cooling plate and the bottom plate are butt-jointed and welded, the water-cooling plate and the bottom plate are placed above the placement plate 1 201 and the placement plate 202 respectively, and then the driving mechanism is controlled to drive the placement plate 1 201 and the placement plate 202 to approach each other, so that the butt joint of the side wall of the bottom plate is aligned with the welding groove on the surface of the water-cooling plate, and until the butt joint is completely embedded in the welding groove;

[0050] S2, then the external controller drives the welding head 4 on the surface of the welding seat 3 to weld the water cooling plate and the bottom plate;

[0051] S3. After one welding is completed, when the placement plate 1 201 and the placement plate 2 202 move away from each other, as the telescopic through rod 17 is pulled out from the inside of the through groove 161, the limit spring 21 on the outer surface of the telescopic through rod 17 will be in a stretched state. As the telescopic through rod 17 is stretched, the telescopic pressure head 19 on the surface of the telescopic through rod 17 will be pulled out from the inside of the limit groove 20. At this time, the limit spring 21 is still in a stretched state. Therefore, under the elastic force of the limit spring 21, the telescopic through rod 17 will drive the scraper brush plate 18 to move back and forth at a certain speed, and the scraper brush plate 18 will clean the slag at the welding point.

[0052] During operation, when the water-cooling plate and the bottom plate are butt-jointed and welded, the water-cooling plate and the bottom plate are placed above the placement plate 1 201 and the placement plate 2 202, respectively. Then, the driving mechanism is controlled to drive the placement plate 1 201 and the placement plate 2 202 to approach each other, so that the butt joint of the bottom plate side wall is aligned with the welding groove on the surface of the water-cooling plate, and until the butt joint is completely embedded in the welding groove. Then, the external controller drives the welding head 4 on the surface of the welding seat 3 to weld the water-cooling plate and the bottom plate. The welding method here is the prior art and is not described in detail in this embodiment. Through the design of the driving mechanism and the cleaning mechanism, the water-cooling plate and the bottom plate can be completely matched and butt-jointed, ensuring the subsequent welding effect of the water-cooling plate and the bottom plate, and the welding position before welding and the position after welding can also be cleaned to ensure the molding quality.

[0053] When the water-cooled plate and the bottom plate are placed on the surfaces of the placement plate 1 201 and the placement plate 2 202 respectively, the control motor drives the horizontal axis 5 to rotate, and the horizontal axis 5 drives the central gear 6 to rotate. The central gear 6 drives the meshing rack 1 8 and the rack 2 10 to move closer to each other, and the rack 1 8 and the rack 2 10 respectively drive the support frame 1 7 and the placement plate 1 201 and the support frame 2 9 and the placement plate 2 202 to move closer to each other. Since the center lines of the placement plate 1 201 and the placement plate 2 202 are located on the same axis, the two are in the same direction. When moving relative to each other, the water-cooling plate and the bottom plate will completely fit and dock, which can ensure the subsequent welding effect of the water-cooling plate and the bottom plate, and is conducive to the subsequent use of the water-cooling plate; when the placement plate 1 201 and the placement plate 2 202 are close to each other, the placement plate 1 201 and the placement plate 2 202 will respectively drive the guide shaft 12 and the guide shaft 2 13 on their surfaces to move in the guide frame 11. Under the limit of the guide frame 11, it can ensure that the placement plate 1 201 and the placement plate 2 202 move on the same axis, which is convenient for the subsequent welding of the water-cooling plate and the bottom plate;

[0054] When the placement plate 1 201 and the placement plate 2 202 are close to each other, the telescopic penetration rod 17 on the surface of one of the cleaning plates 15 will be inserted into the penetration groove 161, and then the limiting unit will clamp the telescopic penetration rod 17 and the scraping brush plate 18 in the penetration groove 161. When one welding is completed, the central gear 6 is controlled to reverse, so that the central gear 6 drives the rack 1 8 and the rack 2 10 to move away from each other, that is, the placement plate 1 201 and the placement plate 2 202 are away from each other. Since the water-cooled plate and the bottom plate have been welded and are not fixed on the placement plate, the water-cooled plate and the bottom plate will not move when the two are away from each other. Then, under the action of the limiting unit, the telescopic penetration rod 17 and the scraping brush plate 18 move at a certain speed, so that the scraping brush plate 18 can clean the welded part after welding, so that the slag falls off, avoiding the slag remaining on the surface of the water-cooled plate and affecting the forming quality of the water-cooled plate.

[0055] After the placement plate 1 201 and the placement plate 202 are close to each other so that the water-cooling plate and the bottom plate are connected, the telescopic through rod 17 will extend into the through groove 161, and the telescopic pressure head 19 will be completely embedded in the limiting groove 20, and the water-cooling plate and the bottom plate are just connected; after one welding is completed, when the placement plate 1 201 and the placement plate 202 are away from each other, as the telescopic through rod 17 is pulled out from the through groove 161, the limiting spring 21 on the outer surface of the telescopic through rod 17 will be in a stretched state. As the telescopic through rod 17 is stretched, the telescopic pressure head 19 on the surface of the telescopic through rod 17 will be pulled out from the limiting groove 20. At this time, the limiting spring 21 is still in a stretched state. Therefore, under the elastic force of the limiting spring 21, the telescopic through rod 17 will drive the scraper brush plate 18 to reciprocate at a certain speed, and the scraper brush plate 18 will clean the slag at the welding point, avoiding manual cleaning by the staff, and the operation is more convenient.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
