Description

Technical Field

[0001] The utility model relates to the technical field of wire harness contraction, in particular to a blowing device. Background Art

[0002] An electronic wiring harness is an electrical component made up of multiple wires or cables tied together. It is widely used in the fields of automobiles, electronic equipment, aerospace, etc. For example, the wiring harness of an automobile sensor is mainly composed of connectors, branches, terminals, etc. The wiring harness is a bridge between different electronic components and is responsible for signal transmission. Therefore, the protection of the wiring harness is of great significance.

[0003] Nowadays, in order to protect the wiring harness from possible damage due to external forces (for example, the sensor wiring harness is damaged by friction, vibration, moisture intrusion, etc.), a protective sleeve (such as a shrink hose) and insulating materials are often used to wrap the sensor wiring harness, and then the shrink hose and the wiring harness need to be shrunk so that the two can fit fully.

[0004] At present, hot air guns are often used for manual heat shrinking. First, an operator is required to place the wire harness in the positioning block, and then another operator uses the hot air gun to manually rotate and bake the shrink hose. The entire operation process requires at least two operators to work at the same time to ensure product output. At the same time, the work intensity of the operator using the hot air gun is relatively high and the operation time is long. Utility Model Content

[0005] The utility model aims to solve the problem of high labor cost and high work intensity of manually shrinking wire harnesses with hot air guns. The utility model provides a blowing device that can realize automatic shrinking of wire harnesses, effectively reduce labor cost and time cost, and is easy to operate.

[0006] In order to solve the above technical problems, the embodiment of the utility model discloses a blowing device, comprising:

[0007] Workbench;

[0008] a heating portion, the heating portion extending along a first direction and spaced apart from the workbench along a second direction, the heating portion comprising an air inlet channel, a heater and a heating surface, the air inlet channel being used for gas to flow in, the heater being used for heating the gas flowing through the air inlet channel, the heating surface being inclined relative to the workbench along a third direction, the heating surface being provided with an air outlet, the air outlet being communicated with the air inlet channel and being arranged toward the workbench;

[0009] A bearing seat, wherein the bearing seat is provided with a receiving groove, wherein the receiving groove is used to receive a wiring harness, wherein the receiving groove includes an outlet end, wherein the outlet end is provided on a side of the bearing seat facing away from the workbench along the second direction, wherein the outlet end is used for allowing the wiring harness to extend out, wherein the bearing seat is connected to the workbench in a slidable manner along the first direction, and can move along the first direction to be located below the heating surface, wherein the first direction is perpendicular to the second direction, and the third direction is arranged at an acute angle to the second direction.

[0010] By adopting the above technical solution, heating parts capable of heating and blowing air (for example, simultaneous heating and blowing air, or heating first and then blowing air, or blowing air first and then heating air) are arranged at intervals on the workbench along the second direction, and the heating part includes a heating surface arranged toward the workbench, and the heating surface is inclined relative to the workbench, so that the heating surface can blow hot air toward the workbench; at the same time, a supporting seat capable of moving to below the heating surface along the first direction is provided, and the wiring harness to be shrunk (for example, the wiring harness and the shrink hose wrapped therearound) is placed as a whole in the supporting seat, so that the part to be shrunk (i.e., the part to be shrunk described below) extends out of the outlet end of the supporting seat, so that the part to be shrunk is baked by the hot air blown out by the heating surface, so that the parts to be shrunk of the wiring harness can fit each other.

[0011] Therefore, during the shrinking work using the blowing device of the embodiment of the present application, only one operator needs to manually place the wire harness in the supporting seat, and then the supporting seat can automatically move to the bottom of the heating part (move forward along the first direction), and the heating surface of the heating part blows out hot air to bake the wire harness, completing the shrinking work of the wire harness, and then the same operator takes out the shrunk wire harness, or the wire harness is taken out by auxiliary equipment such as a robotic arm, and then the operator continues to place subsequent wire harnesses.

[0012] The blowing device of the embodiment of the present application can realize semi-automatic shrinking of the wire harness, without the need to use a traditional hot air gun and configure multiple operators for manual baking. The above-mentioned shrinking work only requires one operator, effectively reducing labor costs and time costs, and the operator's work intensity is low and the operation is simple.

[0013] According to another specific embodiment of the utility model, two heating parts are provided, and the heating surfaces of the two heating parts are arranged opposite to each other and spaced apart along a fourth direction, and the two heating surfaces are arranged to be inclined in an "eight" shape relative to the workbench; each heating surface is provided with a plurality of air outlets; and the fourth direction is perpendicular to the first direction.

[0014] By adopting the above technical scheme, the blowing device of the embodiment of the present application is equipped with two heating parts, and the two heating parts are inclined relative to each other in an "eight" shape, so that when the supporting seat moves to the bottom of the heating part, the respective heating surfaces can be jointly directed to the part to be shrunk of the wire harness, and the hot air blown out from the heating surface can fully cover the part to be shrunk, so that the part to be shrunk can be heated evenly, thereby improving the shrinkage efficiency and the quality of the wire harness, and reducing the energy consumption of the heater in the heating part.

[0015] According to another specific embodiment of the present utility model, the heating portion is provided with two air inlet passages, and each of the air inlet passages extends along the first direction.

[0016] By adopting the above technical solution, two air inlet channels are opened in the heating part. Only one air inlet channel can be used, or gas can be supplied to both air inlet channels at the same time, thereby increasing the gas supply amount and effectively improving the flexibility of the design of the heating part and the pipeline arrangement (for example, the routing design of the first pipeline between the air supply part and the air inlet channel described later).

[0017] According to another specific embodiment of the utility model, the blowing device also includes an air supply part, the air supply part and the air inlet channel are connected through a first pipe, the first pipe is provided with a first valve, and the air supply part is arranged on the workbench; the first valve can be switched between an open state and a closed state; in the open state, the first valve is used to enable the air supply part to supply the gas to the air inlet channel, and in the closed state, the first valve is used to stop the air supply part from supplying the gas.

[0018] With the above technical solution, the air supply unit (such as an air compressor) is used to supply gas to the air inlet channel of the heating unit. A first pipeline is provided between the air supply unit and the air inlet channel. The first pipeline includes a first valve (such as a solenoid valve). The first valve can switch the first pipeline between two states. For example, when the first valve is opened, the air supply unit can supply gas to the air inlet channel. When the wiring harness in the support seat is baked by hot air, the first valve is closed, and the air supply unit stops supplying air. Therefore, only the first valve needs to be opened and closed to realize the two actions of supplying and stopping air supply, which is convenient to operate and saves costs.

[0019] According to another specific embodiment of the present invention, the heating portion is provided with a heating channel, and the heating channel extends along the first direction; the heater is provided in the heating channel, and the heating portion is made of a heat-conducting material.

[0020] By adopting the above technical solution, a heating channel is provided in the heating part, and a heater (such as a heating rod) is installed in the heating channel. The heating part is made of a heat-conducting material as a whole, and the heat generated in the heating channel can be transferred to the above-mentioned air inlet channel to heat the gas flowing into the air inlet channel. This arrangement can achieve the temperature increase of the gas flowing into the heating part at a relatively low cost.

[0021] According to another specific embodiment of the utility model, the blowing device also includes a cooling part, which is arranged at a distance from the workbench along the second direction; the cooling part is provided with a connected air inlet and a cooling hole, the cooling hole is arranged toward the workbench, the support seat can move along the first direction to be located below the cooling hole, the air inlet and the air supply part are connected by a second pipe, the second pipe is provided with a second valve, and the second valve is arranged on the workbench; the second valve can switch between an open state and a closed state; in the open state, the second valve is used to enable the air supply part to supply the gas to the air inlet, and in the closed state, the second valve is used to stop the air supply part from supplying the gas.

[0022] By adopting the above technical solution, the blowing device of the embodiment of the present application can also be provided with a cooling part for automatically cooling the wire harness after shrinkage, and the cooling part includes an air inlet for air intake and a cooling hole (for example, a plurality of cooling holes) for blowing natural wind, and each cooling hole is connected to the air inlet. When the wire harness in the support seat is completely shrunk, the support seat can be reset to the initial position backward along the first direction. At this time, along the second direction, the cooling part is located above the support seat, and the cooling hole faces the support seat in the initial position. The air flowing into the cooling part through the air inlet can flow out through the cooling hole, so as to blow natural wind to the wire harness in the support seat after shrinkage to achieve cooling. There is no need to wait for the naturally cooled wire harness after shrinkage, which effectively improves the work efficiency of the entire shrinkage process, prevents operators from being scalded when taking the wire harness, and ensures personnel safety.

[0023] According to another specific embodiment of the utility model, the blowing device also includes a control box, the control box is arranged on the workbench, the control box is electrically connected to the heater in the heating channel, and the control box is used to control the heater to start or stop heating.

[0024] According to another specific embodiment of the utility model, the accommodating groove includes a first groove and a second groove that are connected; the first groove extends along the second direction, the outlet end is arranged at an end of the first groove along the second direction that is away from the second groove, and the second groove extends along a fourth direction, and the fourth direction is perpendicular to the second direction.

[0025] By adopting the above technical solution, in the bearing seat, the receiving groove for receiving the above wiring harness is L-shaped, so that the part of the wiring harness to be contracted can extend out of the above outlet end.

[0026] According to another specific embodiment of the utility model, two accommodating grooves are provided, and the two accommodating grooves are spaced apart along the first direction.

[0027] By adopting the above technical solution, two spaced-apart accommodating grooves are opened in the supporting seat, so that two wire harnesses can be shrunk at the same time. When one operator is configured, the two wire harnesses can be shrunk at the same time, which can largely ensure the employee's working time (i.e. the time for placing the wire harnesses and taking out the wire harnesses) and the overall time for the shrinking work, thereby improving the output efficiency of shrinking the wire harnesses. In addition, it can also ensure that the size of the above-mentioned heating part is small, and there is no need to further increase the volume of the heating part.

[0028] According to another specific embodiment of the utility model, the accommodating groove also includes a third groove, which extends along the fourth direction and is connected to the second groove; the first groove includes a first part and a second part that are connected, and the second groove includes a third part and a fourth part that are connected; along the first direction, the size of the third groove is a first size, the size of the first part is a second size, and the size of the second part is a third size, the third size is larger than the second size, and the second size is not smaller than the first size; the size of the third part is a fourth size, and the size of the fourth part is a fifth size, the fourth size is larger than the third size, and the fourth size is smaller than the fifth size.

[0029] By adopting the above technical solution, along the first direction, the size of each part of the first groove is smaller than the size of each part of the second groove, that is, the wiring harness remains clamped in the first groove and will not produce a large displacement along the second direction, so as to ensure that the part to be shrunk can extend out of the outlet end so as to be baked by hot air.

[0030] According to another specific embodiment of the utility model, the workbench is provided with a first sliding part and a driving member, the first sliding part extends along the first direction, and along the second direction, a second sliding part is provided at the bottom of the supporting seat, the driving member is connected to the second sliding part, and the driving member can drive the second sliding part to move forward and backward along the first sliding part.

[0031] According to another specific embodiment of the utility model, the blowing device also includes an air supply part, the driving part is a cylinder, the cylinder and the air supply part are connected by a third pipe, the third pipe is provided with a third valve, and the third valve can switch between an open state and a closed state; in the open state, the third valve is used to extend the cylinder to drive the second sliding part to move backward along the first direction, and in the closed state, the third valve is used to retract the cylinder to drive the second sliding part to move forward along the first direction.

[0032] According to another specific embodiment of the utility model, the blowing device also includes a tray, which is arranged at the top of the second sliding portion along the second direction, and is spaced apart from the supporting seat along the fourth direction, and the tray extends along the fourth direction, and the tray is used to accommodate a part of the wiring harness; the fourth direction is perpendicular to the first direction.

[0033] By adopting the above technical solution, the tray can accommodate a part of the wire harness (i.e. the part of the wire harness extending out of the second slot), thereby grouping the wire harness and ensuring that the wire harness will not be thrown on the workbench at will, thereby preventing the wire harness from being dragged or entangled during the back-and-forth movement of the supporting base, effectively improving the stability of the overall work flow of the blowing device and ensuring the quality of the wire harness.

[0047] See also Figure 1 The embodiment of the present application provides a blowing device 1, comprising a workbench 10, a heating unit 20 and a bearing seat 30. The workbench 10 is an operating table for the entire blowing device 1, and the bearing seat 30 is used to align the wire harness ( Figure 1 The sensor harness (not shown in the figure) is positioned, for example, a sensor harness, and another example is a car sensor harness), the heating unit 20 can blow hot air to the sensor harness in the support seat 30 (described in detail later). When the heating unit 20 bakes the sensor harness in the support seat 30 with hot air, the part of the sensor harness to be shrunk (for example, the part wrapped with the shrink hose) can shrink, so that the shrink hose can fit tightly with the harness.

[0048] like Figure 1 As shown, Figure 1 The workbench 10 shown as an example is a rectangular plate-like structure as a whole, but the embodiment of the present application is not limited to this. For example, the workbench 10 can also be circular, elliptical, trapezoidal, square, triangular and other shapes. For another example, table legs, pulleys and other components can be set at the bottom of the workbench 10. As long as it can be used as an operating table for the hair dryer 1, it belongs to the protection scope of the embodiment of the present application.

[0049] Continue reading Figure 1 , Figure 1 Two heating parts 20 are shown exemplarily, and each heating part 20 is a rectangular block structure. For example, the heating part 20 of the embodiment of the present application can be made of a copper block with good thermal conductivity. The embodiment of the present application does not limit the number, shape, and material of the heating part 20. For example, three, four, or other heating parts 20 can be set. The heating part 20 can be set to a circular, elliptical, trapezoidal, square, triangular, or other shape. The heating part 20 can be made of other metal or non-metal materials with thermal conductivity (such as aluminum, aluminum alloy, graphite, etc.). As long as the heating part 20 can face the sensor harness in the bearing seat 30 and can achieve thermal conductivity, it belongs to the protection scope of the embodiment of the present application.

[0050] It can be seen that the two heating parts 20 are respectively arranged along the first direction (such as Figure 1 The two heating parts 20 extend in the second direction (as shown in the X direction). Figure 1 ) is spaced apart from the above-mentioned workbench 10.

[0051] In one possible implementation, see Figure 1 and Figure 2The blowing device 1 of the embodiment of the present application further includes a fixing portion 70 , and the fixing portion 70 includes a fixing frame 701 and a fixing rod 702 connected to each other.

[0052] For example, Figure 1 and Figure 2 As shown, the fixing frame 701 includes two first cross bars 7011 , two vertical bars 7012 and two second cross bars 7013 .

[0053] Exemplarily, the two first cross bars 7011 are respectively arranged along a first direction (such as Figure 1 The first cross bar 7011 extends in the fourth direction (as shown in the X direction) and is fixed on the workbench 10. Figure 1 The Y direction shown in FIG. 1 is set at intervals.

[0054] The two vertical poles 7012 are respectively along the second direction (such as Figure 1 The bottom of the two vertical rods 7012 (i.e. Figure 1 One end indicated by the Z2 direction in the middle) is respectively connected to the corresponding first cross bar 7011, so that the two vertical rods 7012 are also arranged at intervals along the fourth direction.

[0055] The two second crossbars 7013 extend along the fourth direction respectively, and one of the second crossbars 7013 is connected to the top of the two vertical poles 7012 (i.e. Figure 1 Another second cross bar 7013 is connected to the bottom of the two vertical poles 7012 (i.e. Figure 1 Another second cross bar 7013 is also connected between the two first cross bars 7011 and fixed on the workbench 10.

[0056] The embodiment of the present application does not limit the arrangement of the fixing frame 701 (for example, the number, size, shape, etc. of the first cross bar 7011, the vertical bar 7012 and the second cross bar 7013). As long as it can serve as the fixing frame of the heating part 20 (which will be explained later), it belongs to the protection scope of the embodiment of the present application.

[0057] Exemplarily, the fixing portion 70 further includes the fixing rod 702. Figure 1 Four lines along the first direction (such as Figure 1 The fixing rod 702 is provided with a fixing rod 702 extending in the X direction shown in the figure, but the embodiment of the present application does not limit this. One end of the fixing rod 702 and a second cross bar 7013 (i.e. Figure 1 The second cross bar 7013) on the side indicated by the middle Z1 direction is connected.

[0058] For example, see Figure 1It can be seen that the two fixing rods 702 are respectively fixed with the above-mentioned heating parts 20, and the two heating parts 20 are arranged along the fourth direction (such as Figure 1 , and along the third direction (as shown in the Y direction) are arranged oppositely and spaced apart. Figure 1 The two heating parts 20 are arranged obliquely relative to the workbench 10, and the two heating parts 20 are arranged along the second direction (such as Figure 1 The fourth direction is spaced from the first direction (as shown in the Z direction) and the workbench 10; Figure 1 The X direction shown in FIG.

[0059] It should be noted that the third direction is exemplarily the inclination direction of the heating surface 202 (described later) relative to the workbench 10. Figure 1 In the figure, the heating surface 202 of the left heating unit 20 (i.e., the side indicated by the Y1 direction) is exemplarily indicated as the tilting direction E direction relative to the workbench 10, and the heating surface 202 of the right heating unit 20 (i.e., the side indicated by the Y2 direction) is exemplarily indicated as the tilting direction F direction relative to the workbench 10. When the blowing device 1 is provided with only one heating unit 20, the third direction may be the E direction or the F direction, which is not limited in the embodiment of the present application.

[0060] That is, in a possible implementation manner, the fixing frame 701 is a fixing frame between the heating unit 20 and the workbench 10, and is arranged along the second direction (such as Figure 1 Z direction shown in FIG), one end of the fixing frame 701 (ie Figure 1 The side indicated by the Z2 direction in the middle) is connected to the workbench 10, and the other end of the fixed frame 701 (i.e. Figure 1 The fixing rods 702 are connected to one side of the fixing frame 701 in the Z1 direction, and the fixing rods 702 extend along the first direction, and the heating unit 20 is fixed on two of the fixing rods 702.

[0061] The embodiment of the present application does not limit the number, size, and shape of the fixing rods 702. For example, the fixing rods 702 can also be set to five, seven, or other numbers. As long as the heating part 20 can be fixed and tilted relative to the workbench 10, it falls within the protection scope of the embodiment of the present application.

[0062] Continue reading Figure 1 Furthermore, the heating unit 20 includes an air inlet passage 201 , a heater (not shown in the figure) and a heating surface 202 .

[0063] According to the above description, the heating unit 20 is arranged along the third direction (such as Figure 1The E direction and / or F direction shown in FIG. 1 ) is tilted relative to the workbench 10. Based on this, the heating surface 202 is also tilted relative to the workbench 10 along the third direction, that is, the third direction is tilted relative to the second direction (such as Figure 1 However, the heating portion 20 is tilted relative to the workbench 10 along the third direction, which is only one possible implementation. As long as the heating surface 202 can be tilted relative to the workbench 10 along the third direction, it belongs to the protection scope of the embodiment of the present application.

[0064] In a possible implementation manner, the heating surfaces 202 of the two heating units 20 are arranged opposite to each other along the fourth direction, and the two heating surfaces 202 are arranged to be inclined in an "eight" shape relative to the workbench 10 .

[0065] See also Figure 1 and Figure 2 The heating surface 202 is provided with a plurality of air outlets 2021, each of which is connected to the air inlet channel 201, and the plurality of air outlets 2021 are arranged toward the workbench 10. The embodiment of the present application does not limit the number, size, and shape of the air outlets 2021, as long as they are connected to the air inlet channel 201 and can blow air to the sensor harness in the bearing seat 30 (which will be described later), they all belong to the protection scope of the embodiment of the present application.

[0066] Each heating unit 20 is provided with an air inlet passage 201. For example, Figure 1 It is shown that each heating unit 20 is provided with two air inlet channels 201, but the embodiment of the present application does not limit the number of air inlet channels 201. The heater (not shown in the figure, such as a heating rod) is installed in at least one of the air inlet channels 201. The air inlet channel 201 is used for the flow of gas, and the heater is used to heat the gas flowing through the air inlet channel 201. For example, each air inlet channel 201 extends along a first direction (such as Figure 1 X direction shown in FIG.

[0067] See also Figure 2 Combined with Figure 3a and Figure 3b The bearing seat 30 is provided with a receiving groove 301, and the receiving groove 301 is used to receive the wiring harness, and the receiving groove 301 includes an outlet end 30111 (such as Figure 3a The outlet end 30111 is disposed on one side of the support base 30 facing away from the workbench 10 along the second direction (ie Figure 2 The side indicated by the Z1 direction in the figure), such as Figure 2 and Figure 3a As shown, the outlet end 30111 is used to allow a portion of the wire harness 80 (ie, the to-be-contracted portion 801 to be described later) to extend out.

[0068] Continue reading Figure 2 Combined with Figure 3a and Figure 3b In a possible implementation manner, two receiving grooves 301 are provided, and the two receiving grooves 301 are arranged along a first direction (such as Figure 2 The embodiment of the present application does not limit the number of the accommodating slots 301. For example, one, three, or other accommodating slots 301 may be provided on the bearing seat 30. As long as they can be used to accommodate the wire harness 80 and allow the to-be-contracted portion 801 (described later) of the wire harness 80 to extend out of the above-mentioned outlet end 30111, they all fall within the protection scope of the embodiment of the present application.

[0069] Further, see Figure 1 and Figure 2 The supporting base 30 is arranged along a first direction (such as Figure 1 and Figure 2 The heating surface 202 is slidably connected to the workbench 10 in the X direction shown in the figure, and can move along the first direction to a position below the heating surface 202 (exemplarily, along the Figure 1 and Figure 2 The first direction is the direction indicated by X1, wherein the first direction is perpendicular to the second direction.

[0070] Using the above technical solution, along the second direction (such as Figure 1 and Figure 2 ), heating units 20 capable of heating and blowing air (for example, simultaneous heating and blowing air, or heating first and then blowing air, or blowing air first and then heating air) are arranged at intervals on the workbench 10, and the heating unit 20 includes a heating surface 202 arranged toward the workbench 10, and the heating surface 202 is inclined relative to the workbench 10, so that the heating surface 202 can blow hot air toward the workbench 10; at the same time, a supporting seat 30 capable of moving along a first direction to below the heating surface 202 is provided, and the wire harness 80 to be shrunk (for example, the wire harness 80 and the shrink hose wrapped therearound) is placed as a whole in the supporting seat 30, so that the part to be shrunk (that is, the part to be shrunk 801 described later) extends out of the outlet end of the supporting seat 30, so that the part to be shrunk 801 is baked by the hot air blown out by the heating surface 202, so that the parts to be shrunk 801 of the wire harness 80 can fit each other.

[0071] Therefore, during the shrinking work of the blowing device 1 of the embodiment of the present application, only one operator needs to manually place the wire harness 80 in the supporting seat 30, and then the supporting seat 30 can automatically move to the bottom of the heating part 20 (move forward along the first direction), and the heating surface 202 of the heating part 20 blows out hot air to bake the wire harness 80, completing the shrinking work of the wire harness 80, and then the same operator takes out the shrunk wire harness 80, or, the wire harness 80 is taken out by auxiliary equipment such as a robotic arm, and then the operator continues to place subsequent wire harnesses 80.

[0072] The blowing device 1 of the embodiment of the present application can realize semi-automatic shrinking of the wire harness 80, without the need to use a traditional hot air gun and configure multiple operators for manual baking. The above-mentioned shrinking work only requires one operator, effectively reducing labor costs and time costs, and the operator's work intensity is low and the operation is simple.

[0073] In one possible implementation, see Figure 1 and Figure 2 , two air inlet channels 201 are provided in each heating unit 20, and each air inlet channel 201 is provided along the fifth direction (such as Figure 2 The fifth direction extends along the first direction (as shown in the A direction in FIG. Figure 2 ) is parallel to or intersects the X direction shown in . Figure 1 and Figure 2 As shown in the figure, each air inlet channel 201 extends along the extension direction of the heating portion 20, that is, exemplarily, the fifth direction (such as Figure 2 A direction shown in FIG) and a first direction (as shown in FIG). Figure 2 However, the air inlet channel 201 may also extend obliquely relative to the extension direction of the heating portion 20 in the heating portion 20, that is, the fifth direction may also intersect the first direction at an angle, and the embodiment of the present application does not limit this. As long as it can ensure that the gas can pass into the heating portion 20, it belongs to the protection scope of the embodiment of the present application.

[0074] In one possible implementation, see Figure 1 and Figure 2 The blowing device 1 of the embodiment of the present application further includes an air supply unit 40. The air supply unit 40 and the first valve 100 are arranged on the above-mentioned workbench 10.

[0075] The air supply part 40 and the air inlet passage 201 are connected through a first pipe 110, and the first pipe 110 is provided with a first valve 100 (for example, a solenoid valve), and the first valve 100 is arranged on the workbench 10. Exemplarily, one end of the first pipe 110 is first connected to the air supply part 40 (not shown in the figure), and the other end of the first pipe 110 is then connected to the air inlet of the first valve 100, and then led out from the air outlet of the first valve 100 until it is connected to the air inlet passage 201.

[0076] The first valve 100 can be switched between an open state and a closed state. In the open state of the first valve 100, the first valve 100 is used to control the air supply unit 40 to supply gas to the air inlet passage 201. In the closed state of the first valve 100, the first valve 100 is used to control the air supply unit 40 to stop supplying gas. Exemplarily, the air supply unit 40 is an air compressor, into which compressed air is introduced.

[0077] In one possible implementation, see Figure 1 and Figure 2 The heating portion 20 is further provided with a heating channel 203 , in which the heater is arranged. Figure 1 and Figure 2 It is exemplarily shown that each heating portion 20 is provided with two heating channels 203, but the embodiment of the present application does not limit the number, size, and shape of the heating channels 20, as long as they can accommodate the above-mentioned heaters, they all fall within the protection scope of the embodiment of the present application.

[0078] Exemplarily, the heating channel 203 is arranged along the sixth direction (eg Figure 2 The sixth direction extends along the first direction (as shown in the B direction). Figure 2 ) is parallel to or intersects the X direction shown in . Figure 1 and Figure 2 As shown in the figure, each heating channel 203 extends along the extension direction of the heating portion 20, that is, exemplarily, the sixth direction (such as Figure 2 B direction shown in FIG) and the first direction (as shown in FIG. Figure 2 However, the heating channel 203 may also extend obliquely in the heating portion 20 relative to the extension direction of the heating portion 20, that is, the sixth direction may also intersect the first direction at an angle, and the embodiment of the present application does not limit this. As long as the above-mentioned heater can be arranged in the heating channel 203, it belongs to the protection scope of the embodiment of the present application.

[0079] In one possible implementation, see Figure 1 and Figure 2 The blowing device 1 of the embodiment of the present application further includes a control box 50 , and the control box 50 is disposed on the workbench 10 .

[0080] The control box 50 is electrically connected to the heater (eg, heating rod) in the heating channel 203 (wires not shown in the figure), and the control box 50 is used to control the heater to start heating, or the control box 50 can control the heater to stop heating.

[0081] In one possible implementation, see Figure 2 The blowing device 1 of the embodiment of the present application further includes a cooling portion 90, the cooling portion 90 is arranged along the second direction (such as Figure 2 10) is spaced apart from the workbench 10. Exemplarily, the cooling unit is arranged along 90 along the fourth direction (such as Figure 2 Meanwhile, one end of the cooling portion 90 along the first direction (i.e. Figure 2 The end indicated by the X1 direction in the middle) is fixed with the above four fixing rods 702.

[0082] See also Figure 2 and Figure 4 , Figure 4 The cooling unit 90 is shown in a perspective view. The cooling unit 90 is provided with an air inlet 901 and a cooling hole 902 connected to each other. Figure 2 The cooling hole 902 is arranged toward the workbench 10. Figure 4 Eight cooling holes 902 are shown by way of example, but the embodiment of the present application does not limit the number, size, and shape of the cooling holes 902. As long as the cooling holes 902 can face the workbench 10 so that the above-mentioned support seat can slide to the bottom of the cooling holes 902 along the first direction, they are all within the protection scope of the embodiment of the present application.

[0083] like Figure 2 and Figure 4 As shown, the air inlet 901 and the air supply part 40 are connected via a second pipe 210 , and the second pipe 210 is provided with a second valve 200 (eg, a solenoid valve), and the second valve 200 is arranged on a workbench.

[0084] The second valve 200 can switch between an open state and a closed state. In the open state of the second valve 200, the second valve 200 is used to enable the gas supply part 40 to supply gas to the gas inlet 901. In the closed state of the second valve 200, the second valve 200 is used to stop the gas supply part 40 from supplying gas.

[0085] In one possible implementation, see Figure 2 The control box 50 includes a first display screen 501 and a second display screen 502 , and the control box is also provided with a start button 503 and a stop button 504 .

The control box 50 starts to control the heater in the heating channel 203 to heat. The first valve 100 controls the air supply unit 40 to start supplying gas to the air inlet channel 201. At this time, the gas flowing into the air inlet channel 201 can be heated and flow out through the multiple air outlets 2021 on the heating surface 202 to the portion 801 to be shrunk (such as the portion 801 to be shrunk) of the wiring harness 80 in the bearing seat 30. Figure 2 As shown), hot air is blown out to bake and shrink the part 801 to be shrunk.

[0087] When the temperature reaches the first set value, the control box 50 controls the heater in the heating channel 203 to stop heating, and when the temperature is lower than the first set value, the control box 50 controls the heater in the heating channel 203 to start heating. In this process, the first display screen 501 can display the heating temperature of the heater at any time.

[0088] The control box 50 can control the blowing of the hot air. For example, when heating is no longer needed, the stop button 504 can be pressed to stop heating, and at the same time, the first valve 100 controls the gas supply part 40 to stop supplying gas.

[0089] Afterwards, the support base 30 moves backward along the first direction (eg Figure 1 The second valve 200 controls the air supply unit 40 to start supplying gas to the air inlet 901 of the cooling unit 90, and the gas flows out through the cooling hole 902 to the wiring harness 80 (e.g. Figure 2 The part to be shrunk 801 shown in the figure blows out natural wind to cool down the shrunk part to be shrunk 801. The second display screen 502 can display the blowing time of the natural wind in this process.

[0090] Exemplarily, the control box 50 is further provided with a buzzer 505, and if the temperature rise value of the heater is higher than the first set value, the buzzer 505 can sound an alarm.

[0091] In one possible implementation, see Figure 3a and Figure 3b Combined with Figure 2 The receiving groove 301 includes a first groove 3011 and a second groove 3012 (such as Figure 3a and Figure 3b As shown), the wiring harness 80 includes a portion to be shrunk 801, a fifth portion 802, a sixth portion 803 and a seventh portion 804 connected to each other (as shown in FIG. Figure 2 shown).

At this time, the part 801 to be contracted of the wire harness 80 is moved along the Figure 3a The outlet end 30111 extends out in the Z1 direction.

[0094] Further, the second groove 3012 is used to accommodate the sixth portion 803 of the wiring harness 80, that is, the sixth portion 803 is accommodated in the second groove 3012 and will not be moved along the fourth direction (such as Figure 3a At this time, the seventh part 804 connected to the sixth part 803 extends out of the supporting seat 30 along the fourth direction.

It can be seen that the first size L1 and the second size L2 are smaller than the third size L3, and the first size L1 of the third groove 3013 is not larger than the second size L2 of the first portion 30112 of the first groove 3011. Figure 3b It is exemplarily shown that the first size L1 and the second size L2 are equal, and the third groove 3013 is used to limit the above-mentioned eighth part 805 of the wiring harness 80, that is, compared with other parts of the wiring harness 80, the eighth part 805 (such as the signal line) is smaller in size.

[0100] Along the first direction (such as Figure 3b The size of the third portion 30121 is a fourth size L4, the size of the fourth portion 30122 is a fifth size L5, the fourth size L4 is larger than the third size L3 of the second portion 30113 of the first groove 3011, and the fourth size L4 is smaller than the fifth size L5.
