Description

Technical Field

[0001] The utility model relates to the technical field of sensor tooling, in particular to a sensor welding tooling. Background Art

[0002] The wheel speed sensor is a sensor used in the anti-lock braking system of the car to measure the wheel speed. The main parts of the wheel speed sensor include the chip and the frame. The frame is a fixed structure for installing the chip. First, insert the chip into the chip slot of the frame. At this time, the pins of the chip and the inserts of the frame are in contact with each other. Then, the chip pins and the frame inserts are welded. During welding, the chip pins and the frame inserts need to fit tightly to ensure the welding effect.

[0003] Normally, the entire skeleton with the chip installed is placed in the tooling profiling, and then the chip pins and the skeleton inserts are manually pressed to ensure that they fit as closely as possible. However, this method has some problems: 1) There is still a gap between the chip pins and the skeleton inserts, which cannot be eliminated by manual pressing, resulting in a loose weld between the two; 2) The tooling profiling cannot be adjusted, and the molded skeleton inevitably has dimensional errors. Therefore, after the skeleton is placed in the tooling profiling, the skeleton is likely to tilt, which creates risks in subsequent welding; 3) The tooling profiling cannot be adjusted, and different skeletons cannot be distinguished when they are placed, which makes it easier to misinstall and reduce processing efficiency; that is, some skeletons with different specifications and models but small size differences can be placed in the same tooling profiling; 4) It is impossible to press a large number of skeletons at one time by hand, and the welding efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the tooling profiling of the frame cannot be adjusted, and the chip pins and the frame inserts in the tooling profiling are not well fitted, resulting in poor welding. The utility model provides a sensor welding tool, which can improve the welding quality and welding efficiency between the sensor chip and the frame, and improve the overall processing efficiency of the sensor.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a welding tool for a sensor, wherein the sensor comprises a frame and a chip, the frame is provided with an insert, the chip comprises a chip pin, and the chip pin is connected to the insert; the welding tool comprises:

[0006] A workbench, provided with a plurality of placement slots, each of which is used to accommodate the skeleton and the chip;

[0007] A clamping assembly is connected to the workbench in a manner that it can move along a first direction, and a side of the clamping assembly facing the workbench includes a plurality of clamping parts, and the plurality of clamping parts correspond to the plurality of placement grooves one by one;

[0008] A clamping assembly is embedded and connected to the workbench in a manner that it can move along the second direction, and the clamping assembly includes a plurality of clamping parts, and the plurality of clamping parts correspond to the plurality of placement grooves one by one;

[0009] A driving assembly, wherein the driving assembly is capable of driving the clamping assembly to move along the first direction, and is capable of driving the clamping assembly to move along the second direction, so that the welding tool is switched between a locked state and a released state;

[0010] In the locked state, the multiple pressing parts press the chip pins and the plug-in sheets that are in contact with each other, and the skeleton is clamped by the corresponding clamping parts; in the loosened state, the multiple pressing parts are spaced apart from the corresponding chip pins and the plug-in sheets, and the skeleton is spaced apart from the corresponding clamping parts.

[0011] By adopting the above technical solution, the pressing assembly can press the sensor (i.e., the chip and the frame connected to the chip) placed in the placement groove in the first direction under the drive of the driving assembly, and the clamping assembly can clamp the frame placed in the placement groove in the second direction under the drive of the driving assembly, so that the entire welding tool is in a locked state. At this time, the pressing part in the pressing assembly can eliminate the gap between the chip pins and the frame inserts, ensure that the chip pins and the frame inserts are firmly welded, and effectively improve the welding quality and effect of the chip pins and the frame inserts.

[0012] On the other hand, the pressing assembly can be driven by the driving assembly to detach the sensor (i.e., the chip and the frame connected to the chip) placed in the placement groove in a first direction, and the clamping assembly can be driven by the driving assembly to detach the sensor placed in the placement groove in a second direction, so that the entire welding tool is in a loose state. At this time, the welded chip and frame can be taken out, or another batch of chips and frames to be welded can be placed in the placement groove, and then the locking state is switched again to perform the second welding work, eliminating the low quality and low efficiency defects brought by the traditional manual pressing welding method.

[0013] On the other hand, traditional manual pressing can only weld a maximum of three sensors, while the pressing assembly and clamping assembly of the welding tooling of the present application can simultaneously press and clamp sensors in multiple placement slots (for example, six placement slots), further improving welding efficiency.

[0014] In addition, traditional tooling profiling cannot adjust the placement slot in the second direction. When the clamping assembly of the embodiment of the present application switches from a loosened state to a locked state, if the skeleton in one or more of the placement slots is not suitable (for example, it is installed incorrectly as other models), the clamping assembly cannot clamp. Therefore, it is easy to identify and distinguish different models of skeletons, avoid the phenomenon of different skeletons being loaded into welding tooling, and improve processing efficiency.

[0015] At the same time, even if the skeleton is of the same model, there will be dimensional errors. In the traditional tooling profiling, the skeleton is prone to tilt even if it is placed in, which is more likely to cause risks in subsequent welding. The welding tooling of the embodiment of the present application is provided with a clamping assembly, which can clamp multiple skeletons simultaneously, ensure that multiple skeletons are placed without warping, and ensure that multiple skeletons are on the same plane, thereby improving welding stability and safety.

[0017] According to another specific embodiment of the utility model, the driving assembly also includes a first spring, one end of the first spring is connected to the workbench, and the other end is connected to the fixed plate, and in the locked state, the first spring is compressed by the fixed plate; the handle can be detached from the bottom of the stop portion, and the first spring can rebound in the direction away from the workbench along the first direction, so that the clamping assembly switches to the released state.

[0018] According to another specific embodiment of the utility model, the clamping assembly also includes a pressing plate, which is detachably nested in the fixing plate, and the multiple clamping parts are protruding from the pressing plate. The pressing plate is provided with a plurality of through grooves, and the plurality of through grooves correspond one by one to the plurality of placement grooves. The chip pins and the inserts in each of the placement grooves can be exposed to the corresponding through grooves along the first direction.

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0048] 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.

[0049] See also Figure 1 and Figure 2An embodiment of the present application provides a welding tool 1, which is used to press a sensor 2 (such as a wheel speed sensor) before welding.

[0050] See also Figure 3 and Figure 4 The sensor 2 of the embodiment of the present application includes a frame 21 and a chip 22. The frame 21 and the chip 22 are placed together in the welding tool 1 of the embodiment of the present application.

[0051] The top of the frame 21 (eg Figure 4 An insert sheet 211 is provided in the Z1 direction shown in FIG. 2 . The insert sheet 211 is located at the bottom of the chip 22 . Figure 3 and Figure 4 Only the position of the plug-in 211 is schematically shown, and the specific structure of the metal plug-in 211 is not shown. However, it is easy to understand that the plug-in 211 is a metal connecting wire embedded in the skeleton 21, which is used to electrically connect to the chip 22. The embodiment of the present application does not limit the structure of the plug-in 211.

[0052] The chip 22 includes a chip pin 221 and a chip body 222 connected to each other. The chip body 222 is fixed in the frame 21 (for example, the frame 21 is provided with a chip slot, and the chip body 222 is installed in the chip slot); the chip pin 221 is overlapped on the top of the frame 21 (such as Figure 4 The chip pin 221 is in contact with the above-mentioned inserting piece 211.

[0053] See 1 to Figure 4 After the chip pins 221 and the inserts 211 are in contact, further welding (e.g., spot welding) is required. However, although the chip pins 221 and the inserts 211 are in surface contact, there may be gaps between them. These gaps can be observed by human eyes, or they may be gaps that cannot be observed but affect the welding effect. Therefore, the welding tool 1 of the embodiment of the present application provides a clamping assembly 4 for clamping the chip pins 221 and the inserts 211.

[0054] At the same time, since the skeleton 21 in the sensor 2 has a dimensional error after injection molding, if the skeleton 21 is only placed in a tooling profiling (such as the workbench 3 in the welding tooling 1 of the embodiment of the present application), since the tooling profiling cannot be adjusted, the skeleton 21 is likely to tilt, causing risks in subsequent welding. Therefore, the welding tooling 1 of the embodiment of the present application also provides a clamping assembly 5 for clamping the skeleton 21.

[0055] The welding tool 1 according to the embodiment of the present application will be described in detail below.

[0056] See also Figure 1 and Figure 5 , Figure 5The exploded view of the welding tool 1 according to the embodiment of the present application is shown as an example. The welding tool 1 according to the embodiment of the present application comprises: a workbench 3, a pressing assembly 4, a clamping assembly 5, and a driving assembly 6.

[0057] See also Figure 1 and Figure 5 Combined with Figure 4 The workbench 3 is provided with a plurality of placement slots 30 , each placement slot 30 is used to accommodate the above-mentioned skeleton 21 and chip 22 .

[0058] Exemplarily, the workbench 3 is a rectangular plate-shaped structure, but the embodiment of the present application does not limit the shape of the workbench 3, and it can also be in a square, trapezoidal, elliptical or other shapes.

[0059] See also Figure 1 , Figure 2 and Figure 5 , Figure 1 and Figure 2 They are three-dimensional images of welding tool 1 from different perspectives. Figure 1 The N side of the welding tool 1 along the fifth direction is shown as an example. Figure 2 The M side of the welding tool 1 along the fifth direction is shown. By way of example, it can be seen that the workbench 3 includes two groups of placement slots 30, that is, the two groups of placement slots 30 are arranged along the fifth direction (eg Figure 5 The X direction shown in the figure) is located on both sides of the workbench 3, and each group of placement slots 30 includes three placement slots 30. However, the embodiment of the present application is not limited to this, that is, the workbench 3 can also be provided with only one group of placement slots 30, for example, only on the front side of the workbench 3 (for example Figure 1 The side indicated by the X2 direction, or, for example Figure 5 Alternatively, it may be arranged only on the rear side of the workbench 3 (e.g. Figure 1 The side indicated by X1 in the figure, or, for example Figure 5 The side indicated by the X2 direction); accordingly, each group of placement slots 30 may include one, two, five, or other number of placement slots 30.

[0060] See also Figure 1 , the pressing assembly 4 is pressed along a first direction (such as Figure 1 The Z direction shown in FIG. 1 is movably connected to the workbench 3, and the side of the clamping assembly 4 facing the workbench 3 (i.e. Figure 1 The side indicated by the Z2 direction in the middle) includes multiple pressing parts 41, and the multiple pressing parts 41 correspond one by one to the above-mentioned multiple placement grooves 30.

[0061] It should be noted that Figure 1Three clamping parts 41 are shown as an example. Combined with the above description, it can be seen that the three clamping parts 41 correspond to the three placement slots 30 of the same group. In addition, the embodiment of the present application also includes another three clamping parts 41, which are located at the rear side of the clamping assembly 4 (for example, Figure 1 The side indicated by the X1 direction in the middle) corresponds to the three placement slots 30 arranged on the rear side of the workbench 3. The embodiment of the present application does not limit the number of the clamping parts 41. As long as the clamping parts 41 can correspond to the above-mentioned placement slots 30, they all belong to the protection scope of the embodiment of the present application.

[0062] See also Figure 1 and Figure 5 , the clamping assembly 5 is arranged along a second direction (such as Figure 1 The clamping assembly 5 is embedded and connected with the workbench 3 in a movable manner (in the Y direction shown in FIG), that is, the clamping assembly 5 is embedded in the workbench 3, and the clamping assembly 5 can move along the second direction relative to the workbench 3. The clamping assembly 5 includes a plurality of clamping portions 51, and correspondingly, the plurality of clamping portions 51 correspond to the plurality of placement slots 30 one by one.

[0063] It should be noted that when the workbench 3 is provided with Figure 5 When the two groups of placement slots 30 are shown, the welding tool 1 is provided with two clamping assemblies 5, and the structures and movement principles of the two clamping assemblies 5 are the same, and the only difference is that the two clamping assemblies 5 are arranged along the second direction (such as Figure 1 Therefore, the above text only describes the specific structure of one of the clamping assemblies 5.

[0064] See also Figure 1 and Figure 5 , along the second direction, the drive assembly 6 can drive the clamping assembly 4 along the first direction (such as Figure 1 and Figure 5 The Z direction shown in FIG. 1 ) can also drive the clamping assembly 5 to move in a second direction (such as Figure 1 and Figure 5 Y direction shown in the figure) to move the welding tool 1 in the locked state (such as Figure 6a and Figure 6b ) and a released state (as shown in FIG. 6 ).

[0065] See also Figure 6a and Figure 6b Combined with Figure 4 , Figure 6a The schematic diagram of the structure of the welding tool 1 in a locked state is exemplarily shown; Figure 6b A partial schematic diagram of the clamping assembly 5 of the welding tool 1 in a locked state is shown as an example, wherein Figure 6b The clamping components and drive components are hidden. Figure 6aAs shown, in the locked state, each of the above-mentioned pressing parts 41 of the pressing assembly 4 presses the chip pins 221 and the inserts 211 that are in contact with each other along the first direction; Figure 6b As shown, in the locked state, the clamping portion 51 of the clamping assembly 5 moves along the second direction (eg Figure 6b The corresponding skeleton 21 is clamped (in the Y direction shown in FIG), that is, the skeleton 21 is clamped by the corresponding clamping part 51.

[0066] See also Figure 7a and Figure 7b Combined with Figure 4 , Figure 7a The schematic diagram of the structure of the welding tool 1 in a loosened state is shown as an example; Figure 7b A partial schematic diagram of the clamping assembly 5 of the welding tool 1 in the loosened state is shown as an example, wherein Figure 7b The clamping assembly and the drive assembly are also hidden. Figure 7a As shown, in the released state, the pressing portion 41 of the pressing assembly 4 and the corresponding chip pins 221 and the inserting piece 211 are aligned along a first direction (eg Figure 7a The Z direction shown in FIG. Figure 7b As shown, in the loosened state, the frame 21 and the corresponding clamping portion 51 are aligned along the second direction (eg Figure 7b The Y direction shown in FIG. 1 is spaced apart.

[0067] See also Figures 1 to 5 , adopting the above technical solution, the pressing component 4 can press the sensor 2 (i.e., the chip 22 and the frame 21 connected to the chip 22) placed in the placement groove 30 in the first direction under the drive of the driving component 6, and the clamping component 5 can clamp the frame 21 placed in the placement groove 30 in the second direction under the drive of the driving component 6, so that the entire welding tool 1 is in a locked state. At this time, the pressing part 41 in the pressing component 4 can eliminate the gap between the chip pin 221 and the frame insert 211, ensure that the chip pin 221 and the frame insert 211 are firmly welded, and effectively improve the welding quality and effect of the chip pin 221 and the frame insert 211.

[0068] On the other hand, the pressing component 4 can be driven by the driving component 6 to separate from the sensor (i.e., the chip and the frame connected to the chip) placed in the placement groove 30 along the first direction, and the clamping component 5 can be driven by the driving component 6 to separate from the sensor placed in the placement groove 30 along the second direction, so that the entire welding tool 1 is in a loose state. At this time, the chip 22 and the frame 21 after welding can be taken out, or another batch of chips 22 and frames 21 to be welded can be placed in the placement groove 30, and then switched to the above-mentioned locking state again for the second welding work, eliminating the low quality and low efficiency defects brought by the traditional manual pressing welding method.

[0069] On the other hand, traditional manual pressing can only weld a maximum of three sensors 2, while the clamping assembly 4 and clamping assembly 5 of the welding tooling of the present application can simultaneously press and clamp the sensors 2 in multiple placement slots 30 (for example, six placement slots 30), further improving the welding efficiency.

[0070] In addition, the conventional tooling profiling cannot adjust the placement slot 30 in the second direction. When the clamping assembly 5 of the embodiment of the present application switches from a loosened state to a locked state, if the skeleton in one or more of the placement slots 30 is not suitable (for example, it is mistakenly installed as other models), the clamping assembly 5 cannot be clamped. Therefore, it is easy to identify and distinguish different models of skeletons 21, avoid the phenomenon of different skeletons 21 being loaded into welding tooling, and improve processing efficiency.

[0071] At the same time, even if the skeleton 21 is of the same model, there will be dimensional errors. In the traditional tooling profiling, the skeleton 21 is prone to tilt even if it is placed in, which is more likely to cause risks in subsequent welding. The welding tooling 1 of the embodiment of the present application is provided with a clamping assembly 5, which can simultaneously clamp multiple skeletons 21, ensure that the multiple skeletons 21 are placed without warping, and ensure that the multiple skeletons 21 are on the same plane, thereby improving welding stability and safety.

[0072] See also Figure 6a and Figure 6b Combined with Figure 1 In a possible implementation manner, the above-mentioned locking state of the welding tool 1 of the embodiment of the present application includes a first state and a second state, wherein the first state refers to the state of the clamping assembly 4 in the locking state, and the second state refers to the state of the clamping assembly 5 in the locking state.

[0073] See also Figure 7a and Figure 7b Combined with Figure 1 In a possible implementation manner, the above-mentioned loosened state of the welding tool 1 of the embodiment of the present application includes a third state and a fourth state, wherein the third state refers to the state of the clamping assembly 4 in the loosened state, and the fourth state refers to the state of the clamping assembly 5 in the loosened state.

[0074] That is to say, the driving assembly 6 can drive the pressing assembly 4 to move in a first direction (such as Figure 1 The Z direction shown in FIG. 4 is moved to switch the clamping assembly 4 between the first state and the third state; and the driving assembly 6 is capable of driving the clamping assembly 4 to move in the second direction (such as Figure 1 The clamping assembly 5 moves in the Y direction (shown in FIG. 1 ) to switch between the third state and the fourth state.

[0075] The following will combine the structures of the workbench 3, the clamping assembly 4, and the driving assembly 6 to explain in detail how the clamping assembly 4 switches between the first state and the third state.

[0076] See also Figure 1 and Figure 5 In a possible implementation, the clamping assembly 4 further includes a fixing plate 42, and the clamping portion 41 is disposed on the fixing plate 42. It can be seen that the clamping portion 41 is disposed in a direction along the first direction toward the workbench 3 (the placement groove 30) (such as Figure 1 The Z2 direction shown in FIG.

[0077] The driving assembly 6 includes a handle 61, which is arranged along a second direction (eg Figure 1 and Figure 5 The handle 61 is rotatably connected to both sides of the fixed plate 42; the workbench 3 is provided with a stop portion 31, and illustratively, the stop portion 31 corresponds to the above-mentioned handle 61.

[0078] Exemplarily, the stopping portion 31 is along the fifth direction (eg Figure 1 and Figure 5 The stop bar ( Figure 5 The structure of the stop bar is more clearly shown), but the embodiment of the present application does not limit this. As long as the handle 61 can be abutted against the stop portion 31, it falls within the protection scope of the embodiment of the present application.

[0079] Based on this, see Figure 7a The handle 61 can be moved along Figure 7a The w1 direction shown in the figure is rotated, and then refer to Figure 6a until the handle 61 and the stop portion 31 are rotated in the first direction (such as Figure 6a Further, during the above-mentioned rotation process of the handle 61, the handle 61 moves along the surface of the stop portion 31 until the bottom end of the handle 61 (i.e. Figure 6a The end indicated by the Z2 direction in the middle) is located below the stop portion 31 along the first direction (such as Figure 6a In this process, the fixing plate 42 is driven by the handle 61 to move along the first direction (such as the Z2 direction shown in FIG. Figure 6a The clamping assembly 4 moves in the direction Z2 shown in the figure toward the workbench 3 until the fixing plate 42 abuts against the workbench 3. At this time, the clamping assembly 4 is in the first state mentioned above.

The embodiment of the present application does not limit the connection method of the two ends of the first spring 62 to the workbench 3 and the fixed plate 42 respectively. The two ends of the first spring 62 can be embedded in the workbench 3 and the fixed plate 42 respectively, or other methods can be used.

[0085] Based on this, see Figure 6a Combined with Figure 5 In combination with the above description, when the pressing assembly 4 is in the first state, the first spring 62 is fixed to the fixing plate 42 along the Figure 6a Then, when the handle 61 originally abutting the lower part of the stop portion 31 is moved along Figure 6a The first spring 62 can be disengaged in the direction of W2 shown in FIG. 1 , away from the workbench 3 in the first direction (eg Figure 6a 6a, then at this time, the clamping assembly 4 is reset to switch from the first state to the above-mentioned third state.

[0086] See also Figure 5 Combined with Figure 1 In a possible embodiment, the pressing assembly 4 further includes a guide column 44 and a guide sleeve 45.

[0089] The upper end of each limiting portion 46 (i.e. Figure 1 and Figure 5 The end indicated by the Z1 direction in the middle is connected to the side of the fixing plate 42, and the lower end is along the direction toward the workbench 3 (such as Figure 1 At the same time, the workbench 3 is provided with a stop pin 32. It should be noted that Figure 1 Only the position of the limit pin 32 is shown, and the specific structure of the limit pin 32 is not shown. Figure 6a and Figure 7a The structure of the limit pin 32 is shown, and it is easy to understand that the limit pin 32 is a component protruding from the side of the workbench 3, and the limit portion 46 can abut against the limit pin 32, so the embodiment of the present application does not limit the structure of the limit pin 32.

[0090] See also Figure 6a In the first state of the clamping assembly 4, along the first direction (such as Figure 6a The Z direction shown in FIG), the lower end of the limit portion 46 and the limit pin 32 are spaced apart; see Figure 7a In the second state of the clamping assembly 4, the lower end of the limiting portion 46 abuts against the bottom of the limiting pin 32 along the first direction (ie Figure 7a The side indicated by the Z2 direction).

[0091] The following will focus on the structures of the workbench 3 and the clamping assembly 5 and combine the above description of the structure of the driving assembly 6 to further explain in detail how the clamping assembly 5 switches between the second state and the fourth state.

In a possible implementation, the clamping assembly 5 further includes a guiding portion 52, which is arranged along the second direction (such as Figure 5 and Figure 8 The guide portion 52 extends in the Y direction (in the Y direction shown in FIG), and the end portion of one side of the guide portion 52 protrudes out of the workbench 3 along the second direction. The clamping portion 51 of the clamping assembly 5 is connected to the guide portion 52 at intervals along the second direction.

[0093] Exemplarily, the clamping portion 51 is arranged along a first direction (eg Figure 5 and Figure 8 A clamping block extending in the Z direction (shown in FIG. 1 ).

[0094] Exemplarily, the guiding portion 52 is a guiding block extending along the second direction. Exemplarily, the clamping portion 51 and the guiding portion 52 are integrally formed, but the embodiment of the present application does not limit this.

[0095] See also Figures 8 to 10 In a possible implementation, the workbench 3 is provided with a through slot 33 and a plurality of receiving slots 34, wherein: Fig.10 The plurality of receiving slots 34 are shown more clearly.

[0096] The through slot 33 is along the second direction (eg Figure 8 and Fig. 9 The plurality of receiving grooves 34 extend along the first direction (eg, the Y direction shown in FIG. 1 ) and penetrate the workbench along the second direction. Figure 8 and Fig. 9 The Z direction shown in FIG. 1 runs through the workbench 3 , and the plurality of accommodating grooves 34 and the plurality of clamping portions 51 correspond one to one.

[0097] See also Figure 8 and Fig.10 , the length L1 of the receiving groove 34 along the second direction (eg Fig.10 ) is greater than the length L2 of the clamping portion 51 along the second direction (as shown Figure 8 As shown), the clamping portion 51 can move in the receiving groove 34 along the second direction.

Correspondingly, a boss 331 is provided inside the through groove 33 of the workbench 3. When the guiding portion 52 is inserted into the through groove 33, there is a receiving space between the groove 520 and the boss 331 along the second direction. The driving assembly 6 further includes a second spring 63, which is arranged in the receiving space. That is, the guiding portion 52 is arranged in the groove 520 and extends along the second direction. One end of the second spring 63 (i.e. Figure 8 The end indicated by the Y2 direction in the middle) is connected to the inner wall of the groove 520, and the other end of the second spring 63 (i.e. Figure 8 The end indicated by the Y1 direction in the figure is connected to the boss 331.

[0106] Based on this, participation Figure 6a In combination with the above description, when the clamping assembly 5 is in the second state, the second spring 63 moves along the Figure 6a Then, when the handle 61 originally abutting against the stop portion 31 below is separated from the stop portion 31, the second spring can move to the left along the second direction (ie, the fourth direction, as shown in FIG. Figure 6a 6a, then at this time, the clamping assembly 4 is reset to switch from the second state to the fourth state.
