Description

Technical Field

[0001] This utility model belongs to the field of automated heat shrink tubing heat shrinking equipment in wire harness production, specifically relating to a multi-module heat shrink tubing heat shrinking equipment that improves heat shrinking efficiency. Background Technology

[0002] In actual wire harness production, one or more types of wires are connected together through processes such as stripping, soldering, and riveting, and then the connection points are covered with heat-shrink tubing to achieve insulation and waterproofing. This constitutes a wire harness. Typically, 50 or 100 such wires are bundled together, with the connection points tied at both ends as bundled wire harnesses for easy handling. For distinction, wire harnesses are divided into those awaiting heat shrinking and those already heat-shrinked.

[0003] For the heat shrinking of the aforementioned wire harnesses, wire harness manufacturers currently use three methods:

[0004] a) Directly heating the heat shrink tubing of the wire harness with a heat gun or similar tool to shrink it. This is a primitive heat shrinking method that will be gradually phased out and eliminated.

[0005] b. The heat-shrinkable tubing is heated and shrunk by flowing the heat-shrinkable wire harness through the heating area. This heat-shrinking method achieves better results in terms of heat shrinking effect and consistency by controlling the flow speed and the temperature of the heating area.

[0006] c. The heat-shrinkable tubing is heated and shrunk by leaving the heat-shrinkable wire harness in the heating area. This heat-shrinking method achieves better results in terms of heat shrinking effect and consistency by controlling the dwell time and temperature of the heating area.

[0007] Based on the heat shrinking process of wire harness heat shrink tubing and the current status of wire harness bundling, the current heat shrinking methods have the following problems:

[0008] As mentioned above, heat shrinking method a, directly heating the heat shrink tubing with a hot air gun or other heating methods: the heat shrinking consistency of the heat shrink tubing is poor, the heat shrinking effect depends on the worker's subjective judgment, and the worker's labor intensity is high; this is a method that wire harness production factories should eliminate.

[0009] As mentioned above, heat shrinking method b involves heating the heat shrink tubing by having the wire harness flow through the heating area. Because the flow distance is relatively large, the wire harness will be pulled to a considerable distance. Therefore, the bindings on both sides of the wire harness connection point must be loosened so that each wire harness can flow through the heating area for heat shrinking. This conflicts with the wire harness manufacturer's requirement that the bindings on both sides of the wire harness connection point not be loosened during the wire harness circulation process.

[0010] As mentioned above, heat shrinking method c involves heat shrinking the heat shrink tubing by leaving it in the heating area. Since the heat shrinking time required is longer than the time it takes for the worker to center the heat shrink tubing on the wire harness and place it in the heating area, there is a waiting time after the worker centers the heat shrink tubing on the wire harness to be heat-shrinked, resulting in wasted cycle time. This cannot meet the wire harness manufacturer's goal of improving production efficiency.

[0011] Based on the above characteristics, existing heat shrink tubing equipment cannot simultaneously meet or fulfill the needs of wire harness manufacturers. Therefore, there is an urgent need to provide a new heat shrink tubing equipment to optimize the wire harness production process and improve efficiency. Utility Model Content

[0012] The purpose of this invention is to overcome the defects in the existing technology and to provide a multi-module heat shrink tube heat shrinking device that improves heat shrinking efficiency.

[0013] The specific technical solution adopted in this utility model is as follows:

[0014] This utility model provides a multi-module heat shrink tubing heat shrinking device to improve heat shrinking efficiency, including a vertical unit and a horizontal unit fixed on a workbench; specifically, a rectangular hole is opened on the table surface of the workbench, and the device composed of the vertical unit and the horizontal unit is respectively placed in the rectangular hole of the workbench, the two are adapted to each other, and the table surface is at the same height.

[0015] The vertical unit includes a first gripper for holding the wire harness, a first heating element for heating the wire harness in the first gripper, and a first wire-springing mechanism for moving the heated wire harness upward and to one side to the wire-dropping area.

[0016] The horizontal unit includes a second clamp for holding the wire harness, a second heating element for heating the wire harness in the second clamp, and a second wire-springing mechanism for moving the heated wire harness to one side to the wire-dropping area.

[0017] The area where the wire falls is located between the vertical unit and the horizontal unit. The trajectory of the wire bundle to be heat-shrinked and the trajectory of the wire bundle that has been heat-shrinked in the vertical and horizontal units do not affect each other.

[0018] Preferably, the first gripper is mounted on a first gripper holder, and the top of the first gripper holder is vertically provided with a first groove for placing the wire harness; the first gripper is located on both sides of the bottom of the first groove for clamping the wire harness that falls into the first groove.

[0019] Preferably, the initial position of the first heating element is located below the first gripper, and it can be moved to the first gripper under the drive of the power source; the first heating element includes two fan-shaped heating plates, which can be separated or closed into a ring by a hinge rod, and the closed ring can accommodate the wire harness to heat the heat shrink tubing.

[0020] Preferably, the first wire-picking mechanism includes a wire-picking mechanism frame and a first wire-picking lever; the wire-picking mechanism frame can move up and down in the vertical direction under the drive of a power source, and a horizontal first wire-picking lever is installed on the top; the first wire-picking lever is initially located below the bottom of the first groove, and one end is rotatably connected to the wire-picking mechanism frame; the first wire-picking lever can push the wire bundle upward out of the first groove, and throw the wire bundle into the falling area by rotation.

[0021] Preferably, the second gripper is mounted on the second gripper holder, and the second gripper holder has a horizontally opened second groove for inserting the wire harness on its side; the second gripper is located on both sides of the bottom of the second groove for clamping the wire harness that enters the second groove.

[0022] Preferably, the initial position of the second heating element is located behind the second gripper, and it can move forward to the second gripper under the drive of the power source; the second heating element includes two fan-shaped heating plates, which can be separated or closed into a ring by a hinge rod, and the closed ring can accommodate the wire harness to heat the heat shrink tubing.

[0024] Preferably, the vertical unit is located to the lower left of the drop line area, and the horizontal unit is located to the right of the drop line area.

[0025] Compared with the prior art, this utility model has the following advantages:

[0026] 1) It meets the requirement that wire harness manufacturing factories are not allowed to untie the bindings on both sides of the wire harness connection points within a short distance: such as Figure 5 As shown, since the two heating zones are spatially close, the existing binding wire harnesses can be connected at both ends without being untied, thus achieving the heat shrink process.

[0027] 2) Efficiency improvement: The reasonable layout of the two heating units and the automatic wire dropping function allow workers to alternately put heat shrink tubing on and off in the two heating zones without waiting time. The putting on and dropping of the tubing do not interfere with each other, which is convenient and greatly improves efficiency. Attached Figure Description

Detailed Implementation

[0037] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0038] In the description of this utility model, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or indirectly connected, i.e., there is an intermediate element. Conversely, when an element is said to be "directly" connected to another element, there is no intermediate element.

[0039] In the description of this utility model, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0040] In this utility model, for ease of description, ... Figure 4 The directions "left," "right," "up," and "down" are used to illustrate the positional relationships of the components in this utility model device. For the horizontal unit, "front" and "rear" refer to... Figure 4 The left and right sides of the line, i.e., the area adjacent to the drop line, are referred to as the "front," and the area farther from the drop line is referred to as the "rear." Unless otherwise specified, the positional relationships in this utility model are described in this way.

[0041] like Figure 1 The diagram shown illustrates the structure of wire harness 003. One or more wires 001 are connected together through processes such as stripping, soldering, and riveting. The connection points are then covered with heat-shrink tubing 002 to achieve insulation and waterproofing, thus forming a wire harness 003. Typically, 50 or 100 wires are bundled together, with the connection points secured at both ends (i.e., bundling points 104). The entire bundle is considered a bundled wire harness 103 for easy distribution. For differentiation, wire harness 003 is divided into wire harnesses awaiting heat shrinking 105 and wire harnesses already heat-shrinked 106.

[0042] This utility model provides a multi-module heat shrink tubing heat shrinking device to improve heat shrinking efficiency. It mainly addresses the difficulties currently encountered by wire harness manufacturing plants, combining the heat shrinking method of wire harness 003 heat shrink tubing 002, and the technical problems to be solved are as follows:

[0043] a. In the prior art, the heat shrinking methods for heat shrink tubing 002 mainly include: flow-through and stationary types. Flow-through, as in heat shrinking method b in the background art, requires the wire harness 003 to flow through a certain length of heating area. This naturally pulls the wire harness 003 from its initial position to a relatively far location. This has been verified in the actual production activities of wire harness manufacturers, and cannot meet the requirement of wire harness manufacturers not to untie the bindings 104 on both sides of the connection part of the wire harness 103. Stationary, as in heat shrinking method c in the background art, fixes the wire harness 104 in a designated position to complete the heat shrinking of the heat shrink tubing 002, without pulling on the wire harness 003. However, the production cycle of stationary heat shrinking is relatively slow and cannot keep up with the pace of worker operations. Therefore, based on stationary heat shrinking, there is room for designing other structures and methods to improve efficiency.

[0044] b. Based on the dwell-type heat shrinking method, seek solutions to improve efficiency by changing the structure and method. In actual production activities in wire harness manufacturing plants, increasing the temperature of the heating zone to shorten the heat shrinking time and improve efficiency has limited effect. This solution cannot solve the aforementioned cycle mismatch problem and also leads to the situation where the wire harness sheath at both ends of the heat shrink tubing is damaged by baking, which is unacceptable for wire harness manufacturing plants. Therefore, a module solution with multiple heating zones is considered. Multiple heating zone modules take turns performing heat shrinking, thus multiplying the heat shrinking efficiency.

[0045] c. The increase in heating area inevitably requires more space; in order to match the time it takes for workers to center the heat shrink tubing on the wire harness and place it into the heating area, based on time calculations in production practice, the structure of dual-module heating area is the best solution.

[0046] like Figure 2 The diagram shows the basic structure of a current-technology deposited heat shrink tubing machine: a module with only one horizontally arranged heating area, and an additional module with a horizontally arranged heating area above the original horizontally arranged heating area. The basic structure is shown below. Figure 3 As shown in the figure, trajectory 116 is the trajectory for delivering the heat-shrinkable wire harness 105 into the upper heating area, trajectory 117 is the trajectory for delivering the heat-shrinkable wire harness 105 into the lower heating area, and trajectory 118 is the trajectory for the heat-shrinkable wire harness 106 to fall down after heat shrinking in the upper heating area. Trajectories 117 and 118 intersect, which means there is mutual interference during actual operation, affecting worker operation and is unacceptable.

[0047] d. Therefore, the arrangement of the dual-module heating area requires the selection of the best structural form, which leads to the following technical issues: To avoid pulling on the wire harness, the distance between the two heating areas should be as small as possible, and they should be arranged at the front of the equipment; an automatic wire dropping method should be adopted to avoid workers wasting time retrieving the wires; the wire feeding and dropping arrangements in the two heating areas should not interfere with each other; the wire dropping area after heat shrinking should be isolated from the wire feeding area before heat shrinking, and they should not interfere with each other.

[0048] Based on the above-mentioned technical problems, this utility model provides a multi-module heat shrink tubing heat shrinking device to improve heat shrinking efficiency, mainly including a vertical unit 101 and a horizontal unit 102 fixed on a workbench 108. Figure 4 As shown, based on a horizontally arranged heating area in the prior art, a vertically arranged heating area is added. Here, the horizontally arranged heating area is named horizontal unit 102, and the vertically arranged heating area is named vertical unit 101; as... Figure 4 When the heat-shrinkable wire harness 105 is placed on the left side of the vertical unit 101, the heat-shrinkable wire harness 106 automatically falls between the vertical unit 101 and the horizontal unit 102.

[0049] The vertical unit 101 and the horizontal unit 102 work together to improve the efficiency of the heat shrink tubing during the heat shrinking process. The working process is described below.

[0050] In the device of this utility model, such as Figure 7 and 8 As shown, the vertical unit 101 mainly includes a first gripper 111, a first heating element 113, and a first wire-springing mechanism 107. The first gripper 111 is used to hold the wire harness 003, the first heating element 113 is used to heat the wire harness 003 in the first gripper 111, and the first wire-springing mechanism 107 is used to move the heated wire harness 003 upward and to one side to the wire-dropping area.

[0051] In the device of this utility model, such as Figure 6 As shown, the horizontal unit 102 mainly includes a second gripper 112, a second heating element 109, and a second wire-springing mechanism 123. The second gripper 112 is used to hold the wire harness 003, the second heating element 109 is used to heat the wire harness 003 in the second gripper 112, and the second wire-springing mechanism 123 is used to move the heated wire harness 003 to one side to the wire-dropping area.

[0052] In the device of this utility model, the wire dropping area is located between the vertical unit 101 and the horizontal unit 102. The entry trajectory of the heat-shrinkable wire bundle 105 in the vertical unit 101 and the ejection trajectory of the heat-shrinkable wire bundle 106 in the horizontal unit 102 do not affect each other. Specifically, as shown... Figure 4As shown, the heat-shrinkable wire harness 105 and the heat-shrinkable wire harness 106 are arranged in two independent areas and will not interfere with each other; trajectory 119 is the trajectory of the heat-shrinkable wire harness 105 entering the heating area of ​​the vertical unit 101, trajectory 120 is the trajectory of the heat-shrinkable wire harness 105 entering the heating area of ​​the horizontal unit 102, trajectory 121 is the trajectory of the heat-shrinkable wire harness 106 from the heating area of ​​the vertical unit 101 to the landing area, and trajectory 122 is the trajectory of the heat-shrinkable wire harness 106 from the heating area of ​​the horizontal unit 102 to the landing area. The four trajectories are independent of each other and do not intersect, so there will be no interference in the actual working process.

[0053] In practical use, a relatively small value for L should be obtained without affecting the heat-shrinkable wire harness 106 falling into the drop area; further optimization should be performed to compress the component size within the width range of M as much as possible to obtain the minimum value of M; further, combined with practical verification, while ensuring that the bundles 104 at both ends of the bundled wire harness 103 can be heat-shrinked one by one in the two heating areas without being untied, the values ​​of L and M should be appropriately adjusted to obtain the optimal structural layout. Figure 5 As shown, this is a preferred structure of the device of this utility model: the equipment is placed in the middle of the workbench 108, and the equipment surface is flush with the workbench 108 surface; the heat-shrinkable wire harness 105 is placed at the front end of the workbench 108 surface, and the worker pulls the heat-shrinkable tubes one by one to the connection point of the wire harness 003 and puts them into the heating area for heat shrinking.

[0054] As a preferred embodiment of this utility model, the structure of the vertical unit 101 is as follows:

[0055] The first gripper 111 is mounted on the first gripper frame, and the top of the first gripper frame has a vertically formed first groove. The size of the first groove should be large enough to accommodate the wire harness 003. The first gripper 111 is located on both sides of the bottom of the first groove, capable of clamping the wire harness 003 that falls into the bottom of the first groove. The initial position of the first heating element 113 is below the first gripper 111, and it can move upward to the first gripper 111 under the drive of the power source. The first heating element 113 includes two fan-shaped heating plates, which can be separated or closed into a ring by a hinge rod, and the size of the closed ring should be large enough to accommodate the wire harness 003, thereby performing a heating and heat-shrinking operation on the heat shrink tubing 002 through the two heating plates. The first wire-clamping mechanism 107 mainly includes a wire-clamping mechanism frame 114 and a first wire-clamping lever 115. Figure 7 As shown, the wire-picking mechanism frame 114 can move vertically up and down under the drive of a power source, and a horizontal first wire-picking lever 115 is installed on top. Figure 8As shown, the initial position of the first wire-picking lever 115 is located below the bottom of the first groove. One end of the first wire-picking lever 115 is rotatably connected to the wire-spreading mechanism frame 114, and the first wire-picking lever 115 can rotate around this connection point as an axis. The first wire-picking lever 115 can push the wire bundle 003 upward out of the first groove, and throw the wire bundle 003 into the falling area by rotating around the axis.

[0056] As a preferred embodiment of this utility model, the structure of the horizontal unit 102 is as follows:

[0057] The second gripper 112 is mounted on the second gripper holder, on the side of the second gripper holder (e.g., Figure 6 As shown in the diagram (in this embodiment, on the left), a second groove is horizontally formed. The second groove should be large enough to accommodate the wire harness 003. Second grippers 112 are located on both sides of the bottom of the second groove, capable of clamping the wire harness 003 that enters the second groove. The initial position of the second heating element 109 is located behind the second grippers 112 (e.g., ...). Figure 4 As shown (right side in this embodiment), it can move forward (left side in this embodiment) to the second gripper 112 under the drive of the power source. The second heating element 109 includes two fan-shaped heating plates, which can be separated or closed into a ring by a hinge rod. The closed ring can accommodate the wire harness 003, and then the heat shrink tubing 002 is heated and heat-shrinked by the two heating plates. The second wire-springing mechanism 123 mainly includes a second wire-pulling rod 110. The second wire-pulling rod 110 is horizontally arranged and initially located below the second groove. One end of the second wire-pulling rod 110 is rotatably connected to the worktable 108, and the second wire-pulling rod 110 can rotate around the connection point. The second wire-pulling rod 110 can throw the wire harness 003 into the wire-dropping area by rotating.

[0058] In addition to the heat shrink tubing heat shrinking device with the aforementioned multi-module design to improve heat shrinking efficiency, this utility model also provides a heating method, which is as follows:

[0059] Place the heat-shrinkable wire harness 105 at the front end of the workbench 108, and slide the heat-shrink tubing 002 to the connection point of the wire 001. Then, sequentially insert it into the first groove of the vertical unit 101 and the second groove of the horizontal unit 102 for heat shrinking. Once the heat-shrinkable wire harness 105 is clamped on the first clamp 111 or the second clamp 112, the heating process for the next heat-shrinkable wire harness 105 can begin.

[0060] When the heat shrink tubing 002 is placed into the first groove of the vertical unit 101, the first gripper 111 clamps the wire harness 003. The two heating plates of the first heating element 113 open and move upward, closing at the position of the wire harness 003, thus beginning the heat shrinking of the heat shrink tubing 002 on the wire 001. After the heat shrinking time is over, the two heating plates of the first heating element 113 open and move downward to their original position before closing again, and the first gripper 111 releases the heat-shrinkable wire harness 106. The wire-splitting mechanism frame 114 of the first wire-splitting mechanism 107 moves upward vertically under the drive of the power source, driving the first wire-picking lever 115 to push the wire harness 003 upward out of the first groove. The first wire-picking lever 115 then rotates around the connection point and rotates a certain angle under the drive of the power source, dropping the heat-shrinkable wire harness 106 into the dropping area. Then, the wire-splitting mechanism frame 114 and the first wire-picking lever 115 of the first wire-splitting mechanism 107 return to their original positions.

[0061] When the heat shrink tubing 002 is placed into the second groove of the horizontal unit 102, the second gripper 112 clamps the wire harness 003. The two heating plates of the second heating element 109 open and move towards the second gripper 112, closing at the position of the wire harness 003, thus beginning the heat shrinking of the heat shrink tubing 002 on the wire 001. After the heat shrinking time is over, the two heating plates of the second heating element 109 open and move to the side to their original position before closing again, and the second gripper 112 releases the heat-shrinked wire harness 106. Driven by the power source, the second wire-picking lever 110 of the second wire-picking mechanism 123 rotates around its axis at the connection point and rotates a certain angle, dropping the heat-shrinked wire harness 106 into the dropping area. Then, the second wire-picking lever 110 rotates and returns to its original position.

[0062] In this embodiment, the heating method is as follows:

[0063] like Figure 5 As shown, the equipment is placed in the middle of the workbench 108, with the equipment surface flush with the workbench 108 surface. The heat-shrinkable wire harness 105 is placed at the front end of the workbench 108 surface, and the worker pulls the heat-shrink tubing one by one to the connection point of the wire harness 003 and places it into the heating area for heat shrinking.

[0064] If the wire harness 003 is first placed in the heating area of ​​the vertical unit 101, the first gripper 111 of the vertical unit 101 will clamp it tightly. The first heating element 113 of the vertical unit 101 will open, move upward, and close again when it reaches the position of the wire harness 003, starting to heat shrink the heat shrink tube 002 on the wire harness 003. The device will heat shrink the heat shrink tube 002 according to the set time. After the heat shrinking time is over, the first heating element 113 of the vertical unit 101 will open, return downward to its original position, and then close again. The first gripper 111 of the vertical unit 101 will release the heat-shrinked wire harness 106, and the first wire spring mechanism 107 of the vertical unit 101 will... Figure 7As shown by the middle arrow, first lift the heat-shrinkable wire harness 106, and the first wire-pulling lever 115 of the vertical unit 101 will... Figure 8 The wire harness 106 is flipped as indicated by the central arc arrow and then moved to the area where the heat-shrinked wire harness has been placed. After these actions are completed, the first wire-springing mechanism 107 of the vertical unit 101 is reset. At this point, one cycle of the vertical unit 102 is completed, and the next wire harness is ready to be placed for heat shrinking.

[0065] Following the previous section, the heat-shrinkable wire harness 105 is placed into the heating area of ​​the vertical unit 101. The first gripper 111 of the vertical unit 101 clamps the heat-shrinkable wire harness 105, allowing the worker to proceed with the next heat-shrinkable wire harness 105. The heat-shrink tubing on the heat-shrinkable wire harness 105 is then aligned with the connection point of the wire harness and placed into the heating area of ​​the horizontal unit 102. The second gripper 112 of the horizontal unit 102 clamps the heat-shrinkable wire harness 105, and the second heating element of the horizontal unit 102... 109 opens and moves forward, reaching the position of the heat-shrinkable wire harness 105 before closing, beginning the heat-shrinking of the heat-shrinkable tube 002 on the wire harness 003. The device will heat-shrink the heat-shrinkable tube 003 according to the set time. After the heat-shrinking time ends, the second heating element 109 of the horizontal unit 102 opens first, returns to its original position, and then closes. The second gripper 112 of the horizontal unit 102 releases the heat-shrinkable wire harness 106, and the second wire-pulling lever 110 of the horizontal unit 102... Figure 6 As indicated by the circular arrow, the heat-shrinkable wire harness 106 is pulled down into the wire drop area, and the second wire pull rod 110 of the horizontal unit 102 is then reset; at this point, one working cycle of the horizontal unit 102 is completed, and the subsequent wire harness 105 to be heat-shrinked is put in for heat shrinking.

[0066] The working processes of the vertical unit 101 and the horizontal unit 102 are carried out alternately. After the heat-shrinkable wire harness 105 is clamped on the first clamp 111 or the second clamp 112, the next heat-shrinkable wire harness 105 can be processed.

[0067] like Figure 6 As shown, this is the wire-picking mode of the horizontal unit 102: After heat shrinking is completed, the second gripper 112 of the horizontal unit 102 opens to release the heat-shrinked wire harness 106, and the second wire-picking lever 110 of the horizontal unit 102 rotates at a certain angle to pull the heat-shrinked wire harness 106 from the heating area of ​​the horizontal unit 102 to the wire-dropping area, thereby realizing the transfer of the heat-shrinked wire harness 106 from the heating area of ​​the horizontal unit 102 to the wire-dropping area; after this action is completed, the second wire-picking lever 110 of the horizontal unit 102 immediately resets.

[0068] like Figure 7As shown, there is a height difference between the heat-shrinkable wire harness 105 and the heating area of ​​the vertical unit 101. To ensure that the heat-shrinkable wire harness 106 can smoothly cross this height from the heating area of ​​the vertical unit 101 and fall smoothly into the wire dropping area, the first wire spring mechanism 107 of the vertical unit 101 has been optimized. See details below. Figure 8 and Figure 7 The first wire-springing mechanism 107's wire-springing mechanism frame 114 will lift the heat-shrinkable wire harness 106 to a certain height. Then, the first wire-pulling lever 115 of the vertical unit 101 will flip, pulling the heat-shrinkable wire harness 106 towards the wire-dropping area. The heat-shrinkable wire harness 106 will fall into the wire-dropping area under the action of gravity, thereby realizing the transfer of the heat-shrinkable wire harness 106 from the heating area of ​​the vertical unit 101 to the wire-dropping area. After completing this series of actions, the first wire-springing mechanism 107 of the vertical unit 101 will then reset.

Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
