Description

Technical Field

[0001] This application relates to the technical field of high-speed chip mounters, and specifically to a wire harness protection device for a high-speed chip mounter. Background Art

[0002] A wire harness, also known as a flexible printed circuit board or a flexible cable, is a connecting wire harness that can be bent, folded back arbitrarily and has a certain flexibility. It is mainly composed of insulating materials, conductors (usually copper) and other covering layers. Wire harnesses are usually used to connect various components inside a device, such as circuit boards, sensors, displays, etc., to achieve the transmission of electricity, signals and data. The characteristics of wire harnesses include: Flexibility: Wire harnesses have good flexibility and can adapt to various complex installation environments and space limitations. Reliability: Wire harnesses use high-quality insulating materials and conductors, have good electrical performance and reliability, and can ensure the stable transmission of electricity, signals and data. Lightweight: Wire harnesses are lighter than traditional cables and are easy to install and maintain. In high-speed chip mounters, wire harnesses play a crucial role. They are responsible for connecting various components inside the device, ensuring that electricity, signals and data can be accurately transmitted to each part, so as to realize the normal operation of the device. At the same time, due to the usually harsh working environment of high-speed chip mounters, such as high temperature, high humidity, high dust, etc., the quality and reliability of wire harnesses have an important impact on the stability and lifespan of the device.

[0003] During the operation of a high-speed chip mounter, various components such as the drive system and the mechanical system are running at high speed. As a medium connecting these components, the wire harness will also move accordingly. Due to the material and structural design of the wire harness, it will encounter vibrations, bending, etc. during high-speed movement, resulting in a change in the position of the wire harness. After friction occurs between wire harnesses, the service life of the wire harness will be reduced. Utility Model Content

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] The following is a further detailed description of the embodiments of the present application in conjunction with the attached Figures 1-4 drawings.

[0027] Example 1

[0028] Please refer to Figures 1-4 , this embodiment provides a technical solution: a wire arrangement protection device for a high-speed mounter, including: a protection frame 1 and a protection mechanism 2. An installation hole for installing on the high-speed mounter is opened on the protection frame 1. The protection frame 1 can be penetrated and connected to the screw on the high-speed mounter through the installation hole and fixed by a nut. At this time, the protection frame 1 can mask the wire arrangement inside to provide protection. The protection mechanism 2 is arranged inside the protection frame 1 and can limit each group of wire arrangements to avoid friction between the wire arrangements during movement.

[0029] The protection frame 1 includes a connecting rod 201 horizontally welded inside the protection frame 1. The connecting rod 201 can provide stable horizontal movement of the structure on the rod inside the protection frame 1. Horizontal grooves are opened on the outer wall of the connecting rod 201 to provide stable fixed connection of the internal structure. A first sleeve 202 is horizontally slidably connected to the connecting rod 201. The first sleeve 202 can provide stable horizontal movement of the first sleeve 202 through the holes opened inside and adapted to the connecting rod 201. An annular groove is opened on the outer wall of the first sleeve 202 to provide stable rotation of the structure outside the first sleeve 202 on the first sleeve 202 during rotation without deviation. A horizontal threaded hole is opened on the first sleeve 202 to provide displacement of the internal structure during rotation.

[0030] The protection frame 1 further includes a threaded screw rod 203 arranged in the horizontal threaded hole of the first sleeve 202. During the rotational displacement of the threaded screw rod 203, one end is pressed and fitted with the connecting rod 201 to fix the first sleeve 202 on the connecting rod 201. A second sleeve 204 is rotatably connected in the annular groove of the first sleeve 202. The second sleeve 204 can reduce friction with the wire arrangement placed above during movement. Limiting plates 205 are welded to both ends of the second sleeve 204. The limiting plates 205 can limit the wire arrangement inside to prevent deviation of the wire arrangement during displacement.

[0031] The protection frame 1 can protect the internal flexible cable, thus preventing the outside from directly contacting the internal flexible cable. By adjusting the position of the first sleeve 202 on the connecting rod 201, the first sleeve 202 can be located directly below the flexible cable. At this time, by rotating the threaded screw rod 203 in the first sleeve 202, after the threaded screw rod 203 rotates and displaces, one end of the threaded screw rod 203 can squeeze against the outer wall of the connecting rod 201, thereby fixing the first sleeve 202. The second sleeve 204 on the outer wall of the first sleeve 202 can rotate, so that the flexible cable on the second sleeve 204 can drive the second sleeve 204 to rotate during movement, thereby reducing friction. And the limiting plates 205 on both sides of the second sleeve 204 can prevent the flexible cable from shifting, so that friction between flexible cables will not occur.

[0032] Embodiment 2

[0033] Please refer to Figures 1-4 , this embodiment provides a technical solution: a flexible cable protection device for a high-speed mounter, including: a fixing plate 206, a guide rod 207, a fixing frame 208, a spring 209, a third sleeve 210 and a rotating roller 211. The protection frame 1 further includes a fixing plate 206 welded to the outer wall of the limiting plate 205. The fixing plate 206 can perform the connection work between structures, and a rectangular hole is opened inside the fixing plate 206, which can connect and fix the internal structures. The guide rod 207 is arranged in the rectangular hole of the fixing plate 206. The guide rod 207 can provide stable vertical displacement work for the structures on the rod, and both ends of the guide rod 207 are vertically welded to the inner wall of the rectangular hole of the fixing plate 206, which can stably fix and connect the guide rod 207 to the inner wall of the rectangular hole of the fixing plate 206.

[0034] A fixed frame 208 slidably connected vertically to the guide rod 207, and the cross-sectional shape of the fixed frame 208 is in the shape of a "U". The "U"-shaped fixed frame 208 can effectively fix and connect the internal structure, and can drive the connected structure to move synchronously during the vertical movement of the fixed frame 208. A spring 209 sleeved on the guide rod 207, and the two ends of the spring 209 are respectively attached to the outer wall of the fixed frame 208 and the inner wall of the rectangular hole of the fixed plate 206. The spring 209 can achieve stable fixed connection, and through the vertical extrusion of the spring 209, the fixed frame 208 on the guide rod 207 is driven to move stably in the vertical direction. A third sleeve 210 horizontally welded to both inner ends of the fixed frame 208. The third sleeve 210 can enable the internal structure to rotate stably. A rotating roller 211 rotatably connected inside the third sleeve 210, and the rotating roller 211 is arranged above the second sleeve 204. The rotating roller 211 can, during the rotation process, cooperate with the second sleeve 204 to limit the upper and lower ends of the wire arrangement, avoiding the phenomenon of the wire arrangement shifting during bending.

[0035] Through the vertical extrusion of the spring 209 on the guide rod 207 inside the fixed plate 206, at this time, the spring 209 will squeeze and displace the bottom fixed frame 208, thereby driving the bottom of the rotating roller 211 rotatably connected inside the fixed frame 208 through the third sleeve 210 to fit above the wire arrangement, avoiding the phenomenon that the wire arrangement shifts out of the second sleeve 204 during the movement and bending of the wire arrangement, and through the rotation of the rotating roller 211, the friction generated when fitting with the wire arrangement can be reduced.

[0036] The implementation principle of a wire arrangement protection device of a high-speed chip mounter in this application is as follows:

[0037] First of all, the protection frame 1 can protect the internal wire arrangement, thus preventing the outside from directly contacting the internal wire arrangement. By adjusting the position of the first sleeve 202 on the connecting rod 201, the first sleeve 202 can be located directly below the wire arrangement.

[0038] Secondly, at this time, by rotating the threaded screw rod 203 inside the first sleeve 202, after the threaded screw rod 203 rotates and displaces, one end of the threaded screw rod 203 can be squeezed against the outer wall of the connecting rod 201, thereby fixing the first sleeve 202. The second sleeve 204 on the outer wall of the first sleeve 202 can rotate, so that the wire arrangement on the second sleeve 204 can drive the second sleeve 204 to rotate during the movement process, thereby reducing friction, and the limiting plates 205 on both sides of the second sleeve 204 can prevent the wire arrangement from shifting, so that friction between wire arrangements will not occur.

[0039] Finally, a vertical extrusion is performed through the spring 209 on the guide rod 207 inside the fixing plate 206. At this time, the spring 209 will extrude and displace the fixing frame 208 at the bottom, thereby driving the bottom of the rotating roller 211 rotatably connected through the third sleeve 210 inside the fixing frame 208 to fit above the wiring harness. This avoids the phenomenon that the wiring harness deviates from the second sleeve 204 during the movement and bending of the wiring harness. Moreover, through the rotation of the rotating roller 211, the friction generated when it fits with the wiring harness can be reduced.

[0040] For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claimed rights.
