Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a welding dust removal device. Background Art

[0002] A battery module is composed of multiple batteries connected in series and / or in parallel. During the assembly process, connectors are used to connect the batteries and the circuit board. Specifically, one end of the connector is welded to the positive or negative electrode of the battery, and the other end is welded to the circuit board to transmit current. To ensure the quality of the welds between the connector and the battery and circuit board, welding dust generated during the welding process must be removed.

[0003] In the prior art, there are two main ways to remove welding dust. The first way is to bond high-temperature glue at the welding position to improve the protection of the welding area. Although this method can improve the protection of the welding area, the dust generated by welding can easily escape to the outside, affecting environmental hygiene, and the bonding accuracy requirements of high-temperature glue are high, which can easily lead to the problem of incorrect bonding position, resulting in poor welding quality. The second way is to set up an additional exhaust mechanism, and the exhaust mechanism performs negative pressure dust removal on the connecting piece. However, in order to ensure the normal operation of the welding device, the exhaust port of the exhaust mechanism needs to maintain a certain distance from the connecting piece. While the exhaust mechanism is exhausting the welding area of ​​the connecting piece, it will also exhaust the external environment. It cannot be guaranteed that the exhaust mechanism only exhausts the welding area of ​​the connecting piece. This results in the rated output power of the exhaust mechanism being different from the actual exhaust power, making it difficult to monitor the actual exhaust power of the exhaust mechanism, thereby affecting the actual dust removal effect.

[0004] Therefore, it is urgent to invent a welding dust removal device to solve the above problems. Utility Model Content

[0037] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0039] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0040] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0041] In the prior art, there are two main ways to remove welding dust. The first way is to bond high-temperature glue at the welding position to improve the protection of the welding area. Although this method can improve the protection of the welding area, the dust generated by welding can easily escape to the outside, affecting environmental hygiene, and the bonding accuracy requirements of high-temperature glue are high, which can easily lead to the problem of incorrect bonding position, resulting in poor welding quality. The second way is to set up an additional exhaust mechanism, and the exhaust mechanism performs negative pressure dust removal on the connecting piece. However, in order to ensure the normal operation of the welding device, the exhaust port of the exhaust mechanism needs to maintain a certain distance from the connecting piece. While the exhaust mechanism is exhausting the welding area of ​​the connecting piece, it will also exhaust the external environment. It cannot be guaranteed that the exhaust mechanism only exhausts the welding area of ​​the connecting piece. This results in the rated output power of the exhaust mechanism being different from the actual exhaust power, making it difficult to monitor the actual exhaust power of the exhaust mechanism, thereby affecting the actual dust removal effect.

[0042] In order to solve the above problems, Figures 1 to 5 As shown, this embodiment provides a welding dust removal device 1000. The welding dust removal device 1000 includes a dust removal mechanism 100, a welding mechanism 200, and a driving mechanism 300. The dust removal mechanism 100 includes a dust removal housing 110 and a negative pressure dust removal assembly 120. The dust removal housing 110 is provided with a dust removal chamber 111. One end of the dust removal housing 110 is provided with an opening 1111 that is in communication with the dust removal chamber 111. The end of the dust removal housing 110 with the opening 1111 abuts against the connecting piece 2000. The output end of the negative pressure dust removal assembly 120 extends into the dust removal chamber 111. The negative pressure dust removal assembly 120 is configured to negatively exhaust the dust removal chamber 111. The welding head 210 of the welding mechanism 200 is accommodated in the dust removal chamber 111. The welding head 210 is configured to weld the connecting piece 2000.

[0043] The welding dust removal device 1000 is configured such that the welding head 210 of the welding mechanism 200 is accommodated in the dust removal chamber 111 of the dust removal mechanism 100, and the output end of the negative pressure dust removal assembly 120 in the dust removal mechanism 100 is extended into the dust removal chamber 111. When the connecting piece 2000 abuts against the opening 1111 at one end of the dust removal chamber 111, the dust removal chamber 111 can be sealed, thereby achieving the welding of the connecting piece 2000 in the dust removal chamber 111, ensuring the welding effect of the connecting piece 2000 during the welding process, and improving the welding quality. Moreover, since the dust removal shell 110 is provided with one end of the opening 1111 abutting against the connecting piece 2000, the rated output power of the negative pressure dust removal assembly 120 can be made the same as the actual output power, thereby facilitating the monitoring of the actual output power of the negative pressure dust removal assembly 120.

[0044] To further improve the dust removal effect during the welding process of the connecting piece 2000, during the welding process, the negative pressure dust removal assembly 120 is activated before the welding mechanism 200 or is activated synchronously with the welding mechanism 200, and the negative pressure dust removal assembly 120 is deactivated after the welding mechanism 200 is deactivated for a preset time. By ensuring that the negative pressure dust removal assembly 120 in the dust removal mechanism 100 is activated before the welding mechanism 200 or is driven synchronously with the welding mechanism 200, it is possible to ensure that the dust removal chamber 111 of the welding mechanism 200 is in a negative pressure state during welding, thereby removing welding dust generated by welding. By ensuring that the negative pressure dust removal assembly 120 is deactivated after the welding mechanism 200 is deactivated for a preset time, the negative pressure state in the dust removal chamber 111 can be maintained after welding is completed, thereby fully removing residual welding dust. It should be noted that in this embodiment, the negative pressure dust removal assembly 120 is activated before the welding mechanism 200, and the welding mechanism 200 is not activated until the preset time after the negative pressure dust removal assembly 120 is activated. The preset time for the negative pressure dust removal assembly 120 to be activated before the welding mechanism 200 is the same as the preset time for the negative pressure dust removal assembly 120 to be deactivated after the welding mechanism 200, to ensure the dust removal effect of the negative pressure dust removal assembly 120. In other embodiments, the negative pressure dust removal assembly 120 and the welding mechanism 200 may be activated synchronously, or the negative pressure dust removal assembly 120 may be activated before the welding mechanism 200 for any period of time, and this embodiment is not specifically limited thereto.

[0045] Specifically, the preset time is 4 to 10 seconds. In this embodiment, the preset time is preferably 5 seconds. After the connecting piece 2000 is sealed and docked with the opening 1111 on the dust removal housing 110, the negative pressure dust removal assembly 120 is activated to perform negative pressure dust removal on the dust removal chamber 111. 5 seconds after the negative pressure dust removal assembly 120 is activated, the welding mechanism 200 is activated, causing the welding head 210 in the dust removal chamber 111 to weld the connecting piece 2000 at the opening 1111. After the welding mechanism 200 completes welding the connecting piece 2000, the welding mechanism 200 is deactivated. At this time, the negative pressure dust removal assembly 120 remains activated and continues to remove dust from the dust removal chamber 111. 5 seconds after the welding mechanism 200 is deactivated, the negative pressure dust removal assembly 120 is deactivated, completing the welding dust removal on the connecting piece 2000. In other embodiments, the preset time can be adjusted arbitrarily within the range of 4 to 10 seconds, and this embodiment does not specifically limit this.

[0046] To further improve the dust removal effect on the connecting piece 2000, at least two groups of negative pressure dust removal components 120 are provided in the dust removal mechanism 100. The at least two groups of negative pressure dust removal components 120 are arranged at intervals along the circumference of the dust removal housing 110, and the output end of each group of negative pressure dust removal components 120 extends into the dust removal chamber 111. By arranging at least two groups of negative pressure dust removal components 120 at intervals along the circumference of the dust removal housing 110, so that the output end of each group of negative pressure dust removal components 120 extends into the dust removal chamber 111 and is activated and closed at the same time, the dust removal effect in the dust removal chamber 111 can be further improved. It should be noted that in this embodiment, two groups of negative pressure dust removal components 120 are provided in the dust removal mechanism 100, and the two groups of negative pressure dust removal components 120 are arranged relatively at equal intervals along the circumference of the dust removal housing 110. In other embodiments, the specific number of negative pressure dust removal components 120 in the dust removal mechanism 100 can also be adjusted according to actual needs. It is only necessary to ensure that the negative pressure dust removal components 120 are arranged at circumferential intervals along the dust removal shell 110. This embodiment does not make specific limitations.

[0047] In addition, the two sets of negative pressure dust removal components 120 in this embodiment are activated and deactivated synchronously to achieve rapid negative pressure extraction and dust removal within the dust removal chamber 111, and are also easy to control. In other embodiments, the two sets of negative pressure dust removal components 120 can also work independently, so that the staff can activate the negative pressure dust removal components 120 according to actual needs.

[0048] Specifically, the negative pressure dust removal assembly 120 includes a negative pressure fan and a negative pressure pipe. One end of the negative pressure pipe is connected to the negative pressure fan, and the other end of the negative pressure pipe extends into the dust removal chamber 111. The operation of the negative pressure fan achieves negative pressure treatment in the dust removal chamber 111. The specific structure of the negative pressure fan and the principle of negative pressure are both prior art and will not be described in detail here.

[0049] In this embodiment, the welding dust removal device 1000 also includes a driving mechanism 300, which can simultaneously drive the dust removal mechanism 100 and the welding mechanism 200 to move toward the direction close to the connecting piece 2000 and make the opening 1111 press against the connecting piece 2000, so that the end of the dust removal shell 110 provided with the opening 1111 presses against the connecting piece 2000, or the driving mechanism 300 can simultaneously drive the dust removal mechanism 100 and the welding mechanism 200 to move toward the direction away from the connecting piece 2000. By setting up a driving mechanism 300 to drive the dust removal mechanism 100 and the welding mechanism 200 to move toward the direction close to the connecting piece 2000 and make the opening 1111 press against the connecting piece 2000, the opening 1111 and the connecting piece 2000 can be automatically pressed against each other, thereby improving the sealing efficiency of the dust removal chamber 111. By simultaneously driving the dust removal mechanism 100 and the welding mechanism 200 to move away from the connecting piece 2000 through the driving mechanism 300, the loading and unloading of the connecting piece 2000 can be facilitated, thereby improving the welding efficiency of the connecting piece 2000.

[0050] Furthermore, the driving mechanism 300 includes a driving member and a detecting member, wherein the driving member is connected to the dust removal mechanism 100 and the welding mechanism 200, and can drive the dust removal mechanism 100 and the welding mechanism 200 to move toward or away from the connecting piece 2000. The detecting member is connected to the driving member and is used to detect the position information of the dust removal mechanism 100 and the welding mechanism 200 relative to the connecting piece 2000. By providing the driving member to drive the dust removal mechanism 100 and the welding mechanism 200 to move toward or away from the connecting piece 2000, and providing the detecting member to detect the position information of the dust removal mechanism 100 and the welding mechanism 200 relative to the connecting piece 2000, it is possible to ensure that the driving member accurately drives the dust removal mechanism 100 and the welding mechanism 200 relative to the connecting piece 2000.

[0051] Specifically, the driving mechanism 300 further includes a control member, which is connected to the detection member and the driving member. The detection member can transmit detection information to the control member, and the control member can control the activation and deactivation of the driving member based on the detection information of the detection member. When the driving member drives the dust removal mechanism 100 and the welding mechanism 200 to move toward the connecting piece 2000 and abut against the connecting piece 2000, the detection member detects that the dust removal mechanism 100 and the welding mechanism 200 have moved into place. At this time, the detection member transmits the detection information to the control member, and the control member controls the driving member to close based on the detection information to maintain the state in which the dust removal housing 110 abuts against the connecting piece 2000. When the driving member drives the dust removal mechanism 100 and the welding mechanism 200 to move in a direction away from the connecting piece 2000, the detecting member detects the relative positions of the dust removal mechanism 100 and the welding mechanism 200 relative to the connecting piece 2000 until the dust removal mechanism 100 and the welding mechanism 200 move to the initial position. At this time, the detecting member transmits the detection information to the control member, and the control member controls the driving member to close according to the detection information, so that the dust removal mechanism 100 and the welding mechanism 200 stop at the initial position.

[0052] It should be noted that, in this embodiment, the driving member is a linear motor, the detecting member is a laser position sensor, and the controller is a PLC controller. The dust removal mechanism 100 and the welding mechanism 200 are both connected to the output shaft of the linear motor, and the linear motor drives the dust removal mechanism 100 and the welding mechanism 200 to move toward or away from the connecting piece 2000. The laser position sensor constantly detects the position information of the dust removal mechanism 100 and the welding mechanism 200 relative to the connecting piece 2000, and the PLC controller controls the start and stop of the linear motor according to the detection information of the laser position sensor. The specific structure and working principle of the PLC controller, linear motor and laser position sensor belong to the prior art and will not be elaborated here. In other embodiments, the driving member may also be a linear cylinder, a screw nut structure or other structures capable of realizing linear drive, the detecting member may also be an ultrasonic position sensor or other position sensor, and the control member may also be other types of controllers, which are not specifically limited in this embodiment.

[0053] In order to further improve the driving accuracy of the driving member on the dust removal mechanism 100 and the welding mechanism 200, the driving mechanism 300 also includes a guide rail and a guide slider, wherein the guide rail extends from one end close to the connecting piece 2000 in a direction away from the connecting piece 2000, and the dust removal mechanism 100 and the welding mechanism 200 are both arranged on the guide slider, and the guide slider slides with the guide rail. By providing a guide rail extending from one end close to the connecting piece 2000 in a direction away from the connecting piece 2000, and providing a guide slider that slides with the guide rail, the dust removal mechanism 100 and the welding mechanism 200 are both arranged on the guide slider. When the driving member drives the dust removal mechanism 100 and the welding mechanism 200 to move in a direction away from or close to the connecting piece 2000, the dust removal mechanism 100 and the welding mechanism 200 can move relative to the connecting piece 2000 along the guide rail under the action of the guide slider, and the flip dust removal mechanism 100 and the welding mechanism 200 are offset during the movement, thereby ensuring the driving accuracy of the driving member.

[0054] It should be noted that in this embodiment, the dust removal mechanism 100 and the welding mechanism 200 are disposed directly above the connecting piece 2000. Therefore, the driving member drives the dust removal mechanism 100 and the welding mechanism 200 in the vertical direction toward or away from the connecting piece 2000, and the guide rail extends upward from the end adjacent to the connecting piece 2000 to provide guidance for the driving of the driving member. In other embodiments, the dust removal mechanism 100 and the welding mechanism 200 can also be disposed below, to the left, or to the right of the connecting piece 2000. In this case, it is only necessary to adaptively adjust the driving direction of the driving member and the extension direction of the guide rail. This embodiment does not specifically limit this.

[0055] In an alternative embodiment, the dust removal housing 110 is cylindrical or prismatic, the opening 1111 is disposed at one axial end of the dust removal housing 110, and the welding mechanism 200 is disposed at the other axial end of the dust removal housing 110. It should be noted that in this embodiment, the dust removal housing 110 is cylindrical, the opening 1111 is disposed at one axial end of the cylindrical dust removal housing 110, and the welding mechanism 200 is disposed at the other axial end of the dust removal housing 110, so that the driving mechanism 300 can drive the opening 1111 on the dust removal housing 110 to connect with the connecting piece 2000. In other embodiments, the dust removal housing 110 can also be configured as a triangular prism, a quadrangular prism, or other prismatic structure, which is not specifically limited in this embodiment.

[0056] Further, if Figure 3 As shown, the welding head 210 housed within the dust removal chamber 111 is capable of emitting a welding laser 211, which is aligned with the area to be welded on the connecting piece 2000. By ensuring that the welding laser 211 is aligned with the area to be welded on the connecting piece 2000, the welding accuracy of the welding laser 211 on the connecting piece 2000 is guaranteed, thereby improving welding precision. It should be noted that the specific structure and welding principles of the welding mechanism 200 are both conventional and will not be further described here.

[0057] Furthermore, to further improve the welding accuracy of the welding laser 211, the vertical projection of one end of the dust removal housing 110 with the opening 1111 on the connecting piece 2000 is adapted to the shape of the area to be welded on the connecting piece 2000. It should be noted that in this embodiment, the area to be welded on the connecting piece 2000 is circular, so the vertical projection of the end of the dust removal housing 110 with the opening 1111 on the connecting piece 2000 is a circular projection of the same shape as the circular area to be welded. In other embodiments, the shape of the vertical projection of the opening 1111 on the connecting piece 2000 can also be adjusted according to the actual shape of the area to be welded, and this embodiment does not specifically limit this.

[0058] As an optional solution, the dust removal housing 110 is made of a plastic material or metal material with high temperature resistance to ensure that the dust removal housing 110 has a certain rigidity, avoid the problem of the dust removal housing 110 being deformed by force during the docking process between the dust removal housing 110 and the connecting piece 2000, and ensure normal welding and dust removal of the connecting piece 2000. It should be noted that in this embodiment, the dust removal housing 110 is made of POM (Polyformaldehyde, also known as Saigang) material. Polyformaldehyde is an engineering plastic with excellent mechanical strength and dimensional stability. It has high strength, modulus, wear resistance, toughness, fatigue resistance and creep resistance, and also has excellent electrical insulation, solvent resistance and machinability. In other embodiments, the dust removal housing 110 can also be made of other plastic or metal materials with high temperature resistance such as PVC (Polyvinyl Chloride), PE (polyethylene) or PU (Polyurethane), which is not specifically limited in this embodiment.

[0059] As an optional solution, the dust removal mechanism 100 also includes an elastic sealing ring 130, wherein the elastic sealing ring 130 is fixed to one end of the dust removal housing 110 having an opening 1111, and the elastic sealing ring 130 can be compressed and clamped between the connecting piece 2000 and the dust removal housing 110. By arranging the elastic sealing ring 130 between the end of the dust removal housing 110 having an opening 1111 and the connecting piece 2000, not only can direct contact between the opening 1111 and the connecting piece 2000 be avoided, thereby improving the protection of the connecting piece 2000 and the opening 1111, but also the elastic compression of the elastic sealing ring 130 itself can be utilized to ensure that the connecting piece 2000 effectively seals the dust removal chamber 111, thereby improving the sealing effect. It should be noted that, in this embodiment, the elastic sealing ring 130 is made of rubber material. The rubber material has good elasticity, toughness and wear resistance, and has a long service life. In other embodiments, the elastic sealing ring 130 can also be made of other elastic materials, which is not specifically limited in this embodiment.

[0060] Furthermore, the elastic sealing ring 130 is bonded to the outer wall of the dust removal housing 110 at the end with the opening 1111. By bonding the elastic sealing ring 130 to the outer wall of the dust removal housing 110 at the end with the opening 1111, the elastic sealing ring 130 can be effectively fixed to the outer wall of the opening 1111. After the welding of the connecting piece 2000 is completed, when the driving member drives the dust removal housing 110 in a direction away from the connecting piece 2000, the elastic sealing ring 130 bonded to the outer wall of the opening 1111 can move along with the dust removal housing 110 in a direction away from the connecting piece 2000, thereby facilitating the welding of the next connecting piece 2000.

[0061] In order to further facilitate the understanding of the welding dust removal device 1000 provided in this embodiment. Figures 1 to 5 The specific working process of the welding dust removal device 1000 is described as follows:

[0062] 1) The driving member drives the dust removal mechanism 100 and the welding mechanism 200 to move upward to a certain height;

[0063] 2) Move the connecting piece 2000 to the bottom of the dust removal mechanism 100 and ensure that the area to be welded on the connecting piece 2000 is aligned with the opening 1111 of the dust removal housing 110 in the vertical direction;

[0064] 3) The driving member drives the dust removal mechanism 100 and the welding mechanism 200 to move downward until the elastic sealing ring 130 provided on the outer wall of the opening 1111 is compressed and clamped between the connecting piece 2000 and the outer wall of the opening 1111;

[0065] 4) Simultaneously start the two negative pressure dust removal assemblies 120 in the dust removal mechanism 100. After the two negative pressure dust removal assemblies 120 have been started for 5 seconds, start the welding mechanism 200 to weld the area to be welded of the connecting piece 2000.
