Description

Technical Field

[0001] The invention relates to the field of welding, and in particular to a welding electrode device and welding equipment. Background Art

[0002] The assembly or connection of some electronic components is achieved through welding technology. Taking the electronic component speed sensor as an example, the parts of the speed sensor include speed measuring gears, chips and terminals, etc. Among them, the chip and the terminal need to be welded by welding equipment to form a connection, and the signal transmission is guaranteed after the two are connected.

[0003] Figure 1a The schematic diagram of the connection between the chip and the terminal of the speed sensor through the welding equipment is shown. Figure 1a As shown, the welding device 1 includes an upper electrode 11 and a lower electrode 12, and the upper electrode 11 and the lower electrode 12 are arranged along a first direction ( Figure 1a The upper electrode 11 and the lower electrode 12 are relatively arranged (as shown in the X direction), the upper electrode 11 and the lower electrode 12 are respectively fixed to the welding equipment through the fixed carrier 15, and the upper electrode 11 and the lower electrode 12 can move along the first direction.

[0004] Figure 1b FIG. 1 shows a partial enlarged view of the connection between the chip 13 and the terminal 14 of the speed sensor through a welding device. Figure 1b As shown, when the chip 13 and the terminal 14 are welded, the chip 13 and the terminal 14 are placed between the upper electrode 11 and the lower electrode 12, wherein the chip 13 is located below the upper electrode 11 and the terminal 14 is located above the lower electrode 12. The upper electrode 11 is moved toward the chip 13 by controlling the welding equipment until it abuts against the chip 13, and the lower electrode 12 is moved toward the terminal 14 until it abuts against the terminal 14. Then, the welding equipment is controlled to energize the upper electrode 11 and the lower electrode 12, and the chip 13 and the terminal 14 are welded. The above process is repeated continuously to achieve welding of the chips 13 and the terminals 14 of more speed sensors.

[0005] Generally, the upper electrode 11 and the lower electrode 12 have the same structure, and the lower electrode 12 is taken as an example to describe the specific structure of the lower electrode 12. Figure 2 A stereogram of the electrode is shown, such as Figure 2As shown, the lower electrode 12 includes a head 121, a middle part 122 and a tail 123 connected in sequence along the first direction. Among them, the head 121 of the lower electrode 12 is used to abut against the welding target (such as the terminal 14), that is, the head 121 of the lower electrode 12 is used as the welding part of the lower electrode 12. Correspondingly, the head of the upper electrode 11 is used to abut against the chip 13. Exemplarily, the cross-section of the head 121 of the lower electrode 12 is square, the cross-sectional size of the head 121 of the lower electrode 12 is about 1.8*1.8mm, and the length of the head 121 in the first direction is about 6-10mm.

[0006] The middle portion 122 of the lower electrode 12 serves to connect the head portion 121 and the tail portion 123 . Exemplarily, the cross section of the middle portion 122 of the lower electrode 12 is circular, and the diameter of the cross section of the middle portion 122 of the lower electrode 12 is about 2 mm.

[0007] The tail portion 123 of the lower electrode 12 is used to be installed in the fixed support 15 of the welding equipment to fix the lower electrode 12. By way of example, the tail portion 123 of the lower electrode 12 is circular in cross section, and the cross-sectional diameter of the tail portion 123 of the lower electrode 12 is about 5 mm.

[0008] As described above, currently only the head 121 of the lower electrode 12 is used as a welding part, that is, the lower electrode 12 is not used as a welding part as a whole. Correspondingly, only the head of the upper electrode 11 is used as a welding part. That is, the middle and tail parts of the lower electrode 12 and the upper electrode 11 are not used as welding parts, which results in a waste of welding materials of the upper electrode 11 and the lower electrode 12.

[0009] In addition, since the welding equipment will weld a plurality of speed sensors, the head of the upper electrode 11 will contact the terminals 14 of different speed sensors multiple times, and the head 121 of the lower electrode 12 will contact the chips 13 of different speed sensors multiple times. Therefore, after the welding equipment welds a plurality of speed sensors, the head of the upper electrode 11 and the head 121 of the lower electrode 12 will be severely worn.

[0010] For example, the surface of the head of the upper electrode 11 and the head 121 of the lower electrode 12 may become rough. At this time, the upper electrode 11 and the lower electrode 12 need to be removed from the fixed carrier 15 of the welding equipment, and the head of the upper electrode 11 and the head 121 of the lower electrode 12 need to be re-polished. After the head of the upper electrode 11 and the head 121 of the lower electrode 12 become smooth from rough, the upper electrode 11 and the lower electrode 12 are re-installed on the fixed carrier 15 of the welding equipment.

[0011] When welding a new speed sensor, the height of the upper electrode 11 and the lower electrode 12 relative to the fixed carrier 15 in the first direction is adjusted manually accordingly, until the upper electrode 11 and the lower electrode 12 are adjusted to a suitable welding height, and the welding of the chip 13 and the terminal 14 of the new speed sensor is continued. Since the upper electrode 11 and the lower electrode 12 can only be roughly moved to a more suitable position manually to fix them, precise adjustment is impossible. Utility Model Content

[0012] The utility model aims to solve the problem of electrode material waste. The utility model provides a welding electrode device and a welding equipment, which can adjust the electrode height through a driving member, thereby improving the electrode material utilization rate and adjustment accuracy.

[0013] In order to solve the above technical problems, the embodiment of the utility model discloses a welding electrode device, comprising:

[0014] A housing, wherein the housing has a receiving portion extending along a first direction, one end of the receiving portion in the first direction has an opening, and the opening is located on an upper surface of the housing;

[0015] an electrode body, inserted into the accommodation portion along the first direction, and having one end extending out of the accommodation portion;

[0016] A driving member is disposed on the housing, and is used to drive the electrode body to move relative to the housing along a first direction.

[0017] With the above technical solution, the head of the electrode body extending out of the accommodating portion abuts against the welding target (such as a chip or terminal) to perform the welding process. When the portion of the electrode body extending out of the accommodating portion is consumed and shortened during the welding process and cannot reach the required length for welding, resulting in poor welding of the workpiece, the electrode body in the accommodating portion can be driven by the driving member to move outward relative to the outer shell along the first direction to a suitable length, and the portion of the electrode body pushed out of the accommodating portion can be used for a new welding process. Compared with the prior art, the electrode that can be used in the prior art is only the head portion, while in the present utility model, the electrode that can be used includes the portion of the initial electrode body extending out of the accommodating portion and the portion of the electrode body that can be pushed out of the accommodating portion. The present technical solution can increase the utilization rate of the electrode body material and reduce the degree of waste of the electrode body material.

[0018] According to another specific embodiment of the present invention, the cross-section of the accommodating portion is in a quadrilateral shape, and the cross-section of the electrode body is in a quadrilateral shape.

[0019] By adopting the above technical solution, the cross-section of the accommodating portion is in a quadrilateral shape, which can fit the electrode body to the maximum extent and prevent axial rotation, thereby fixing the electrode body more stably.

[0020] According to another specific embodiment of the utility model, the shell includes a first surface and a second surface arranged opposite to each other along the second direction, the first surface is provided with a first groove extending a set distance along the first direction, the second surface is provided with a second groove extending a set distance along the first direction, the first groove and the second groove are respectively connected to the accommodating portion along the second direction, and the first groove and the second groove respectively penetrate the upper surface, and the second direction is perpendicular to the first direction.

[0021] By adopting the above technical solution, when installing the electrode, the shell can be pried apart through the first groove and the second groove to allow the electrode body to enter the accommodating portion, and then the shell can be reset. When fixing the electrode body, a lateral clamping force can be provided to the electrode body by squeezing the shell, thereby fixing the electrode body.

[0022] According to another specific embodiment of the utility model, a first threaded hole is provided inside the shell, extending to a set distance along the first direction, and the driving member is a height adjustment screw, which is threadedly connected to the first threaded hole, and one end of the height adjustment screw in the first direction contacts one end of the electrode body.

[0023] By adopting the above technical solution, when the electrode body extending out of the accommodating portion is consumed and shortened during the welding process, resulting in poor welding of the workpiece, the moving distance of the height-adjusting top wire can be controlled, and a driving force can be given to the electrode through the contact surface between the height-adjusting top wire and the electrode, so as to accurately drive the electrode body in the accommodating portion to move outward relative to the outer shell along the first direction. The driving distance can be adjusted accurately to the required electrode length according to the specific operating conditions, thereby ensuring the adjustment accuracy of the electrode body during work.

[0024] According to another specific embodiment of the present invention, the inner diameter of the first threaded hole is greater than the inner diameter of the accommodating portion.

[0025] By adopting the above technical solution, the inner diameter of the first threaded hole is larger than the inner diameter of the accommodating portion. When the height adjustment screw is offset against the inner diameter of the accommodating portion, the height adjustment screw can no longer be pushed into the interior of the outer shell. The length of the first threaded hole is the maximum adjustable length of the height adjustment screw, which limits the end position of the height adjustment screw.

[0026] According to another specific embodiment of the present utility model, the first threaded hole and the accommodating portion partially overlap in the first direction.

[0027] By adopting the above technical solution, when the electrode body is installed into the accommodating portion for the first time, part of the electrode body is placed in the first threaded hole. This part of the electrode body is the new welding part that can be pushed out to the outside of the accommodating portion by the height-adjusting top screw during the subsequent welding process, thereby increasing the usable length of the electrode body.

[0028] For example, the overall length of the electrode body is 10 cm, the length of the portion of the electrode body extending out of the accommodating portion is 2 cm, the length of the accommodating portion is 8 cm, the length of the first threaded hole is 5 cm, and the length of the overlapping portion between the two is 3 cm. The electrode body with an overlapping portion of 3 cm has an increased usable length of the electrode body compared with the prior art. At this time, the usable length of the electrode body is increased from 2 cm to 5 cm, thereby increasing the utilization rate of the electrode body material.

[0029] According to another specific embodiment of the present invention, the cross section of the shell is square.

[0030] By adopting the above technical solution, the cross section of the shell is in a quadrilateral shape, which can fit the fixed carrier to the maximum extent, so that the fixed carrier can better clamp the shell and play a role in fixing the shell.

[0031] According to another specific embodiment of the present invention, the housing is made of a metallic conductive material.

[0032] According to another specific implementation of the present invention, the metal conductive material is brass material.

[0033] With the above technical solution, the shell is made of brass material, which can achieve better electrical conductivity.

[0034] According to another specific embodiment of the utility model, the housing comprises:

[0035] A first part, the first part is used to be inserted into a first through hole of a fixed carrier along the first direction; and

[0036] The second part, the first part protrudes the second part along the second direction and / or the third direction, so that after the first part is inserted into the first through hole, the second part abuts against the fixed carrier, the accommodating portion passes through the second part along the first direction and extends a set distance in the first part, and the third direction is perpendicular to the first direction.

[0037] With the above technical solution, when the first part of the shell is inserted into the first through hole of the fixed mount and the second part abuts against the fixed mount, it means that the shell has been installed in place and there is no need to push the shell further, thus playing the role of installation limit.

[0038] According to another specific embodiment of the present invention, the cross-section of the first part and the cross-section of the second part are both square-shaped, and the cross-section of the second part is larger than the cross-section of the first part.

[0039] The embodiment of the utility model further discloses a welding device, which comprises:

[0040] Fixed carrier;

[0041] In any of the aforementioned welding electrode devices, the housing is connected to the fixed carrier.

[0042] By adopting the above technical solution, the welding electrode device can be installed on the fixed carrier for use by connecting the shell to the fixed carrier.

[0043] According to another specific embodiment of the utility model, the fixed carrier has a first through hole, the first through hole extends through the fixed carrier along the first direction, one end of the housing is inserted into the first through hole, and the side surface of the fixed carrier has a second threaded hole, and the second threaded hole extends along the third direction;

[0044] The welding device further comprises a fixed top screw, which is threadedly connected to the second threaded hole and abuts against the shell to realize the connection between the shell and the fixed carrier.

[0045] By adopting the above technical solution, when installing the welding electrode device, one end of the shell is inserted into the first through hole, and the fixing top screw is threadedly connected with the second threaded hole and abuts against the shell, providing a lateral clamping force to the shell, thereby connecting the shell with the fixed carrier and fixing the welding electrode device. When the welding electrode device needs to be disassembled, the welding electrode device can be disassembled by unscrewing the loose fixing top screw.

[0046] According to another specific embodiment of the present utility model, the number of the second threaded holes is two, and the two second threaded holes are spaced apart along the first direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0077] refer to Figure 3The embodiment of the present application provides a welding device 2, including a welding electrode device 3 and a fixed carrier 41, wherein the welding electrode device 3 includes a housing 31, an electrode body 32 and a driving member 33, wherein the housing 31 is connected to the fixed carrier 41. Figure 3 and Figure 4 As shown, the fixed carrier 41 includes a first through hole 411, a second threaded hole 412 and a fixed top screw (not shown in the figure), and the first through hole 411 is along the first direction ( Figure 3 The outer shell 31 is inserted into the first through hole 411 and abuts against the upper surface 414 of the fixed carrier 41. The side surface 413 of the fixed carrier 41 has a second threaded hole 412. The second threaded hole 412 extends in the third direction ( Figure 3 When installing the welding electrode device 3, one end of the shell 31 is inserted into the first through hole 411 along the first direction, and the fixing top screw is threadedly connected with the second threaded hole 412 and abuts against the shell 31, providing a lateral clamping force to the shell 31, so that the shell 31 is connected with the fixed carrier 41. The welding electrode device 3 is connected with the fixed carrier 41 through the shell 31, and the welding electrode device 3 can be installed on the fixed carrier 41 for use. When the welding electrode device 3 needs to be disassembled, the welding electrode device 3 can be disassembled by loosening and unscrewing the fixing top screw.

[0078] refer to Figures 3 to 6 The housing 31 has a first direction ( Figure 4 The receiving portion 311 extending in the X direction is Figure 6 As can be seen from the figure, one end of the accommodation portion 311 in the first direction has an opening 312, and the opening 312 is located on the upper surface 322 of the housing 31. The electrode body 32, along the first direction ( Figure 5 The electrode body 32 is inserted into the receiving portion 311 in the X direction, and one end thereof extends out of the receiving portion 311. The driving member 33 is disposed on the housing 31, and the driving member 33 is used to drive the electrode body 32 to move relative to the housing 31 along the first direction.

[0079] By adopting the above technical solution, the head of the electrode body 32 extending out of the receiving portion 311 abuts against the welding target object (such as a chip or a terminal) to perform the welding process. When the portion of the electrode body 32 extending out of the receiving portion 311 is consumed and shortened during the welding process and cannot reach the required length for welding, resulting in poor welding of the workpiece, the electrode body 32 in the receiving portion 311 can be driven by the driving member 33 to move outward to a suitable length relative to the housing 31 along the first direction, and the portion of the electrode body 32 pushed out of the receiving portion 311 can be used for a new welding process. Compared with the prior art, the electrode that can be used in the prior art is only the head portion, while in the present utility model, the electrode that can be used includes the portion of the initial electrode body 32 extending out of the receiving portion 311 and the portion of the electrode body 32 that can be pushed out of the receiving portion 311. The present technical solution can increase the utilization rate of the electrode body 32 material and reduce the degree of waste of the electrode body 32 material.

[0080] In some possible implementations, the cross section of the accommodation portion 311 is in a quadrilateral shape, and the cross section of the electrode body 32 is in a quadrilateral shape.

[0081] By adopting the above technical solution, the electrode body 32 can fit the accommodating portion 311 to the greatest extent possible to prevent axial rotation, thereby fixing the electrode body 32 more stably.

[0082] It should be noted that the embodiment of the present application does not impose any specific limitation on the cross-section of the accommodating portion 311 . For example, in other possible implementations, the cross-section of the accommodating portion 311 may also be a circular, pentagonal or other shapes, as long as the accommodating portion 311 can fix the electrode body 32 .

[0083] In some possible implementations, such as Figure 6 and Figure 7 As shown, the housing 31 is arranged along the second direction ( Figure 6 The upper surface 322 is provided with a first groove 313 and a second groove 314 extending along the first direction for a set distance e. The first groove 313 and the second groove 314 are connected to the accommodating portion 311 along the second direction respectively, and the first groove 313 and the second groove 314 pass through the upper surface 322 respectively.

[0084] refer to Figure 6 and Figure 7, a second through hole 320 is provided at the end of the first slot 313, and a third through hole 321 is provided at the end of the second slot 314. The second through hole 320 and the third through hole 321 penetrate the housing 31 along the second direction, and play a role in positioning the end point of the slot. The first slot 313 and the second slot 314 extend along the first direction by a set distance e, and the set distance e is, for example, 8 cm. For example, the set distance e of the first slot 313 and the second slot 314 extending along the first direction can be 7 cm, 9 cm, 10 cm, etc.

[0085] By adopting the above technical solution, when installing the electrode body 32, the shell 31 can be pried open through the first groove 313 and the second groove 314, so that the electrode body 32 enters the accommodating portion 311, and then the shell 31 is reset. When fixing the electrode body 32, a lateral clamping force can be provided to the electrode body 32 by squeezing the shell 31, thereby fixing the electrode body 32.

[0086] In some possible implementations, such as Figure 8 As shown, the housing portion 311 penetrates the second portion 319 along the first direction and extends to a set distance a in the first portion 318. The distance a is the maximum length of the electrode body 32 inside the housing portion 311. In addition, a first threaded hole 315 is provided inside the housing 31, extending to a set distance b along the first direction, an inner diameter c of the first threaded hole 315 is greater than an inner diameter d of the housing portion 311, and the first threaded hole 315 partially overlaps with the housing portion 311 in the first direction.

[0087] It should be noted that the embodiment of the present application does not limit the length of the set distance b extending along the first direction of the first threaded hole 315. For example, the set distance b extending along the first direction of the first threaded hole 315 can be 3 cm, 4 cm, 5 cm, etc.

[0088] When the electrode body 32 is first installed into the accommodating portion 311, part of the electrode body 32 is placed in the first threaded hole 315. This part of the electrode body 32 is a new welding part that can be driven out of the accommodating portion 311 by the driving member 33 during the subsequent welding process, which can increase the use length of the electrode body 32. For example, the overall length of the electrode body 32 is, for example, 10 cm, the length of the portion of the electrode body 32 extending out of the accommodating portion 311 is, for example, 2 cm, the length a of the accommodating portion 311 is, for example, 8 cm, the length b of the first threaded hole 315 is, for example, 5 cm, and the length of the overlapping portion f of the two is, for example, 3 cm. The electrode body 32 with a length of 3 cm in the overlapping portion f is the increased use length of the electrode body 32 compared with the prior art. At this time, the usable length of the electrode body 32 is increased from 2 cm to 5 cm, which increases the utilization rate of the material of the electrode body 32.

[0089] The driving member 33 is a height adjustment screw 33, which is threadedly connected to the first threaded hole 315, and one end of the height adjustment screw 33 in the first direction contacts one end of the electrode body 32. Only when one end of the height adjustment screw 33 contacts one end of the electrode body 32, can the height adjustment screw 33 give a driving force to the electrode body 32 through the contact surface between the two, so as to accurately drive the electrode body 32 in the accommodation portion 311 to move outward relative to the housing 31 along the first direction.

[0090] At the same time, since the inner diameter d of the accommodating portion 311 is smaller than the inner diameter c of the first threaded hole 315, when the length of the height adjustment screw 33 in the outer shell 31 reaches the length b of the first threaded hole 315, in other words, the height adjustment screw 33 reaches the inner diameter 323 of the accommodating portion 311, at this time, the height adjustment screw 33 cannot be pushed into the interior of the outer shell 31, and the end position of the height adjustment screw 33 can be limited.

[0091] In some possible implementations, such as Figure 3 and Figure 4 As shown, the housing 31 is divided into two parts, the first part 318 is used to move along a first direction ( Figure 4 The second portion 319 may be inserted into the first through hole 411 of the fixed carrier 41 along the second direction ( Figure 3 Y direction) and the third direction ( Figure 3 The second part 319 protrudes from the first part 318 along the second direction ( Figure 3 Y direction) protrudes from the first portion 318, or the second portion 319 is along the third direction ( Figure 3 In this way, the portion of the first portion 318 protruding from the second portion 319 is used to abut against the upper surface 414 of the fixed carrier 41, so as to define the end position of the housing 31 inserted into the first through hole 411 of the fixed carrier 41.

[0092] refer to Figures 8 to 10 After the first portion 318 is inserted into the first through hole 411, the second portion 319 abuts against the upper surface 414 of the fixed carrier 41. When the first portion 318 of the housing 31 is inserted into the first through hole 411 of the fixed carrier 41 and the second portion 319 abuts against the fixed carrier 41, it means that the housing 31 has been installed in place and there is no need to push the housing 31 further, which plays a role of installation limit.

[0093] In some possible implementations, such as Figure 8As shown, the cross-section of the first portion 318 and the cross-section of the second portion 319 of the housing 31 are both square, and the cross-section of the second portion 319 is larger than the cross-section of the first portion 318. The cross-section of the housing 31 is square. At this time, the housing 31 can fit the fixed carrier 41 to the maximum extent, so that the fixed carrier 41 can better clamp the housing 31 and play a role in fixing the housing 31.

[0094] It should be noted that the embodiment of the present application does not impose any specific limitation on the cross-section of the shell 31 . For example, in other possible implementations, the cross-section of the shell 31 may also be a circular, pentagonal or other shapes, as long as the shell 31 can be fixed in the fixed carrier 41 .

[0095] In some possible implementations, the housing 31 is made of a metal conductive material. For example, the housing 31 of this implementation is made of brass. During welding, the electrode body 32 needs to be energized to achieve the purpose of welding, and the brass material has a better conductive effect for welding.

[0096] In some possible implementations, such as Fig.10 As shown, the number of the second threaded holes 412 is two, and the two second threaded holes 412 are arranged along the first direction ( Fig.10 X direction) interval setting.

[0097] It should be noted that the embodiment of the present application does not impose any specific limitation on the number of the second threaded holes 412 . For example, in other possible implementations, the number of the second threaded holes 412 may be three, four, five, or the like.

[0098] The installation process of the welding electrode device 3 is described in detail below.

[0099] refer to Figure 3 , Figure 4 and Figure 8 , taking the following electrode as an example, when the electrode body 32 is installed for the first time, the first slot 313 and the second slot 314 can be aligned along the fourth direction ( Figure 4 i direction) and the fifth direction ( Figure 4 The outer shell 31 is opened in the middle j direction to allow the electrode body 32 to enter the receiving portion 311, and then the outer shell 32 is reset. When fixing the electrode body 32, the outer shell 31 can be squeezed to provide a lateral clamping force to the electrode body 32, thereby fixing the electrode body 32. Then, the outer shell 31 is placed in the fixed carrier 41 along the first direction, and the fixing screw is installed and tightened to fix the welding electrode device 3. The head of the electrode body 32 extending out of the receiving portion 311 is brought into contact with the welding target (such as the terminal 14), and then the welding device 2 is controlled to energize the lower electrode to start the welding process.

[0100] During the welding process, the portion of the electrode body 32 extending out of the accommodating portion 311 will become shorter due to consumption during multiple welding processes, and will not be able to reach the required length for welding, resulting in poor welding of the workpiece. At this time, the fixed top screw can be loosened and unscrewed to change the outer shell 31 from a fixed state to an adjustable state. Subsequently, the moving distance of the height-adjusting top screw 33 can be controlled, and a driving force can be given to the electrode body 32 through the contact surface between the height-adjusting top screw 33 and the electrode body 32, so as to accurately drive the electrode body 32 in the accommodating portion 311 to move outward relative to the outer shell 31 in the first direction. The driving distance can be adjusted to the required electrode length according to the specific operating conditions, thereby ensuring the adjustment accuracy of the electrode body 32 during work. Subsequently, the fixed top screw can be retightened, the outer shell 31 is fixed, and a new welding process can be started.

[0101] When the height adjustment screw 33 in the housing 31 reaches the length b of the first threaded hole 315, that is, the height adjustment screw 33 can no longer be pushed into the housing 31, a new electrode body 32 can be replaced. At this time, it is necessary to loosen and unscrew the fixed screw, remove the housing 31 from the fixed support 41, and align the first slot 313 and the second slot 314 along the fourth direction ( Figure 4 i direction) and the fifth direction ( Figure 4 The outer shell is opened in the middle j direction, the remaining electrode body 32 in the accommodating portion 311 is taken out, and a new electrode body 32 is reinstalled in the accommodating portion 311.
