Description

Technical Field

[0001] This utility model relates to an automatic cutting device, and more particularly to an automatic cutting device for automotive wire harnesses applied in the field of automotive wire harness processing technology. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits; without them, there would be no automotive circuitry. Automotive wires are all made of copper multi-core flexible wires, some as thin as a hair. There are many different types of wires in a wiring harness, each with different length requirements for different functions. Due to the importance of automotive wiring harnesses in automotive components, the cutting quality requirements are quite high. Different harnesses require different cutting lengths, necessitating constant monitoring of the cutting quality. However, ordinary cutting devices cannot effectively restrain automotive wiring harnesses, making them prone to deviation during cutting. It is also inconvenient to change blades and adjust the cutting length, significantly impacting cutting quality, making it difficult to observe the quality of the cut harness, and hindering the collection of waste materials.

[0003] Utility model patent CN221715535U discloses an automotive wiring harness processing and cutting device, including a main body, a fixing mechanism, and an adjusting mechanism. The fixing mechanism is located at the upper end of the main body, and the adjusting mechanism is located at the lower end of the main body. This automotive wiring harness processing and cutting device, through the installation of the main body, allows for adjustment of the cutting device's position via a slider during wiring harness cutting. After adjustment, a first electric push rod is activated, driving the cutting device downwards to cut the wiring harness with a cutting blade. When the cutting blade is damaged and needs replacement, a second electric push rod is activated, causing the fixing plates to retract, thus releasing the two fixing plates from fixing the cutting blade, allowing for replacement.

[0004] However, when the cutting device is put into use, the fixing device cannot effectively control the movement of the automotive wiring harness throughout the process, which is prone to deviation and causes cutting errors. The cutting device needs to move up and down multiple times to achieve the cutting effect, which is inefficient. In addition, the waste material is difficult to collect and dispose of during the cutting process, causing environmental pollution. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the fixing device cannot effectively control the movement of the automotive wiring harness throughout the process, which easily leads to deviation and cutting errors. The cutting device needs to move up and down multiple times to achieve the cutting effect, which is inefficient. Furthermore, the waste material is difficult to collect and dispose of during the cutting process, causing environmental pollution.

[0006] To solve the above problems, this utility model provides an automatic cutting device for automotive wiring harnesses, including a drive housing and a device base. The drive housing is disposed on the device base, and a telescopic motor and a cutting housing are disposed on the drive housing. The output end of the telescopic motor is connected to a fixing plate, and a fixing buckle is disposed at one end of the fixing plate. A telescopic measuring plate is fixed on the fixing buckle. A C-shaped drive rod that cooperates with the telescopic measuring plate is disposed inside the drive housing, and multiple springs are disposed between the drive housing and the C-shaped drive rod.

[0007] The inner cavity of the cutting shell is equipped with a drive motor, the output end of which is connected to a cutter head. The cutter head is equipped with a drive gear that mates with one end of the C-shaped drive rod. The base of the device is equipped with multiple conveyor frames and waste collection components.

[0008] In the aforementioned automatic automotive wiring harness cutting device, a telescopic motor mounted on the drive housing drives a telescopic measuring plate to move. By impacting a U-shaped drive rod, the U-shaped drive rod disengages from the drive gear. Simultaneously, a drive motor mounted inside the cutting housing controls a cutter disc to cut the delivered automotive wiring harness.

[0009] As a further improvement of this application, the telescopic ruler measuring plate is provided with multiple scales, and a fixing groove is provided on one side corresponding to each scale. An anti-collision fixing pad is provided at the end of the C-shaped drive rod near the drive gear.

[0010] As a further improvement of this application, anti-collision pads are provided at both ends of the telescopic measuring plate, and a fixing pad that cooperates with one end of the C-shaped drive rod is provided on the drive housing.

[0011] As a further improvement of this application, each conveyor frame is triangular in structure, with multiple drive rollers on the conveyor frame, a control motor at the bottom of the conveyor frame, a control gear connected to the output end of the control motor, a drive chain on the control gear, and multiple control rollers fixed on the drive chain.

[0012] As another improvement of this application, the drive roller is rotatably connected to the conveyor frame via an adjustment plate, and the adjustment plate passes through the conveyor frame and is connected to a telescopic adjustment knob.

[0013] As a further improvement to this application, the waste collection assembly includes a waste collection trough that cooperates with the cutter head and a switch door. The waste collection trough is disposed on the device base, the switch door is disposed on the inner wall of the waste collection trough, and a fixed conveyor frame that cooperates with the conveyor frame is disposed on the waste collection trough.

[0014] In summary, the telescopic motor on the drive housing drives the telescopic measuring plate to move, and the impact of the C-shaped drive rod causes the C-shaped drive rod to disengage from the drive gear. At the same time, the drive motor inside the cutting housing controls the cutter head to cut the conveyed automotive wiring harness. The back-and-forth drive of the telescopic motor ensures that the telescopic measuring plate can impact both ends of the C-shaped drive rod to disengage from the drive gear, greatly improving cutting efficiency. The telescopic measuring plate has an adjustable length to control the cutting length of the automotive wiring harness. The spring design ensures that the C-shaped drive rod returns to its original position after cutting. Multiple conveyor frames on the device base ensure that the automotive wiring harness remains straight during the cutting process, preventing deviation and cutting errors. The waste collection component collects waste during the cutting process. Attached Figure Description

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figures 1-4 An automatic cutting device for automotive wiring harnesses is shown, comprising a drive housing 1 and a device base 2. The drive housing 1 is disposed on the device base 2. A telescopic motor 101 and a cutting housing 102 are disposed on the drive housing 1. The output end of the telescopic motor 101 is connected to a fixing plate 103. A fixing buckle 104 is disposed at one end of the fixing plate 103. A telescopic measuring plate 105 is fixed on the fixing buckle 104. The telescopic motor 101 pushes the fixing plate 103 to move, thereby controlling the horizontal movement of the telescopic measuring plate 105. The fixing buckle 104 improves the stability of the structure. An inverted C-shaped drive rod 106 is disposed inside the drive housing 1 to cooperate with the telescopic measuring plate 105. The device is driven by the collision cooperation between the telescopic measuring plate 105 and the inverted drive rod 106. Multiple springs 107 are disposed between the drive housing 1 and the inverted drive rod 106 to achieve the effect of resetting the inverted drive rod 106.

[0026] The inner cavity of the cutting housing 102 is equipped with a drive motor 108. The output end of the drive motor 108 is connected to a cutter head 109. The drive motor 108 controls the rotation of the cutter head 109 to cut the automotive wiring harness. The cutter head 109 is equipped with a drive gear 110 that cooperates with one end of the U-shaped drive rod 106. The drive gear 110 limits the rotation of the cutter head 109 to achieve the function of delayed cutting, thereby controlling the cutting length. The device base 2 is equipped with multiple conveyor frames 201 and a waste collection assembly. The multiple conveyor frames 201 make it less likely for the automotive wiring harness to shift during the cutting process. The waste collection assembly collects waste during the cutting process.

[0027] Please see Figures 2-4 The telescopic measuring plate 105 has multiple scales, and each scale has a fixing groove 111 on one side. The required length of the automotive wiring harness to be cut is set by fixing the fixing groove 111. The telescopic measuring plate 105 can be replaced to meet different cutting requirements. The end of the C-shaped drive rod 106 near the drive gear 110 is provided with an anti-collision fixing pad 114 to mitigate the collision between the C-shaped drive rod 106 and the drive gear 110. Both ends of the telescopic measuring plate 105 are provided with anti-collision soft pads 112. The drive housing 1 is provided with a fixing soft pad 113 that cooperates with one end of the C-shaped drive rod 106 to mitigate equipment damage caused by collision.

[0028] Before the automotive wiring harness cutting process, the fixing slot 111 is adjusted to set the required length of the automotive wiring harness to be cut. After setting, the automotive wiring harness is introduced into the conveyor frame 201. At the same time, the telescopic motor 101 is started to push the fixing plate 103 to move, thereby controlling the horizontal movement of the telescopic measuring plate 105. When the telescopic measuring plate 105 collides forward with the C-shaped drive rod 106, the C-shaped drive rod 106 disengages from the drive gear 110. The limiting force controlling the rotation of the cutter head 109 by the drive motor 108 is released, and the cutter head 109 rotates to cut the automotive wiring harness. After cutting, the spring exerts pressure on the C-shaped drive rod 106. The moving rod 106 performs a reset operation, limiting the rotation of the cutter head 109. Then, the telescopic motor 101 pulls back the telescopic measuring plate 105 to collide with it, causing the U-shaped drive rod 106 to disengage from the drive gear 110 again. This controls the cutting process and improves the cutting efficiency. The anti-collision soft pad 112, the fixing soft pad 113, and the anti-collision fixing pad 114 protect the equipment during the cutting process and mitigate damage caused by collisions. The conveyor frame 201 prevents the offset of the automotive wiring harness from causing cutting deviations. The waste collection component continuously collects waste during the cutting process to prevent environmental pollution.

[0029] Second implementation method:

[0030] Figures 5-6 The illustrated automatic automotive wiring harness cutting device differs from the first embodiment in that each conveyor frame 201 has a triangular structure. Multiple drive rollers 203 are mounted on each conveyor frame 201, which secure the automotive wiring harness during the cutting process. A control motor 202 is located at the bottom of each conveyor frame 201. A control gear 208 is connected to the output of the control motor 202. A drive chain 207 is mounted on the control gear 208, and multiple control rollers 209 are fixed on the drive chain 207. The control motor 202 controls the movement of the wiring harness through a control mechanism. The control gear 208 rotates, driving the drive chain 207 to move. The control roller 209 on the drive chain 207 drives the automotive wiring harness to move horizontally and cooperates with the drive roller 203 to achieve the effect of fixedly conveying the automotive wiring harness. The drive roller 203 and the conveyor frame 201 are rotatably connected through the adjustment plate 210. The adjustment plate 210 passes through the conveyor frame 201 and is connected to the telescopic adjustment knob 211. The height of the adjustment plate 210 can be adjusted by the telescopic adjustment knob 211 to control the thickness of the conveyed wire to cope with the cutting of automotive wiring harnesses of various sizes.

[0031] Please see Figure 6The waste collection assembly includes a waste collection trough 204 that cooperates with the cutter head 109 and a switch door 205. The waste collection trough 204 is set on the device base 2, and the switch door 205 is set on the inner wall of the waste collection trough 204. A fixed conveyor frame 206 that cooperates with the conveyor frame 201 is set on the waste collection trough 204 to continuously collect waste during the cutting process to prevent environmental pollution. The switch door 205 can remove the waste in the waste collection trough 204 for secondary processing.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
