Description

Technical Field

[0001] The present invention relates to the technical field of wire harness production, and in particular to a device and method for automatically inserting a rear cover assembly of a high-voltage wire harness for a new energy vehicle. Background Art

[0002] High-voltage wiring harnesses for new energy vehicles can be configured for internal and external wiring harness connections in electric vehicles according to different voltage levels. They are primarily used for signal distribution within distribution boxes, enabling efficient and high-quality power transmission and shielding against external signal interference. High-voltage wiring harnesses are the neural network of new energy vehicle high-voltage systems. High-voltage wiring harnesses undergo a series of production steps, including wire cutting, feeding back covers and weather plugs, threading and installation, stripping the outer covering, and cutting the shielding mesh. Currently, the back covers and weather plugs used in high-voltage wiring harnesses are often manually inserted into the wires, resulting in low efficiency, high labor intensity, and a failure to meet the requirements of automated and standardized wiring harness production.

DETAILED DESCRIPTION

[0065] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] See Figure 1As shown in FIG. 3 , the automatic insertion device for the rear cover assembly of the high-voltage wire harness of a new energy vehicle includes a wire carrier 155. The wire carrier is a running platform, that is, it can transfer the wire of a workstation to the next workstation. Two wires 156 are loaded on the wire carrier. After the two wires are loaded on the wire carrier, they are arranged at a distance. It is best if the two wires are at the same height and remain parallel.

[0067] The wire carrier includes a transport platform 157 and two wire pneumatic clamps 158 arranged on the transport platform. The wire pneumatic clamps are arranged on the transport platform with the wire pneumatic clamps facing upward, and the wire is placed on the wire pneumatic clamps from above the transport platform for clamping; one wire pneumatic clamp clamps one wire, and after the two wire pneumatic clamps clamp the corresponding wires, the two wires are arranged parallel to each other at the same height. When the wire needs to be taken away, the wire pneumatic clamps can be opened.

[0068] See Figure 4-11 As shown, the component warehouse 159 has at least one material tray 104 for storing the rear cover components, and the material tray can be moved in and out of the component warehouse; two different rear cover components are arranged side by side on the material tray; one rear cover component is the rear cover 107, and the other rear cover component is the rain plug 106, and the rear cover 107 and the rain plug 106 both have two threading holes 160 for two wires to pass through.

[0069] The component material warehouse 159 includes a material frame 100 and a material frame lifting mechanism 101. One side of the material frame 100 is the filling side, and the other side is the feeding side. The feeding side of the material frame 100 is close to the side of the waiting station; the waiting station is a station where the back cover component sent out from the component material warehouse waits to be clamped; the inside of the material frame 100 is a discharge space connected to the filling side and the feeding side. The discharge space has an upper and lower height, and a plurality of upper and lower discharge stations are arranged in the upper and lower height directions in the discharge space.

[0070] A material tray 104 is placed in the discharge station within the material frame 100. The material tray 104 is placed horizontally into the discharge station from the filling side. The material tray 104 is inserted from the filling side of the material frame 100 into the discharge station. After the material tray 104 is loaded into the discharge space, it is arranged in an upper and lower layer. During use, the material tray 104 can be moved out of the material frame 100 from the feeding side of the material frame 100, or from the filling side of the material frame 100. The specific time when the material tray 104 is inserted into the material frame 100 and moved out of the material frame 100 will be explained in the following use process. Two component placement stations 105 for different rear cover components are provided on the upper surface of the material tray 104. Each component placement station 105 includes multiple rows of component stations arranged on the upper surface of the material tray. One component station is used to place a rain plug 106, and the other component station is used to place a rear cover 107. The two rear cover components are placed together on a material tray 104 and can be transported to the corresponding positions at the same time.

[0071] The material frame lifting mechanism 101 is located outside the material frame and drives the material frame 100 to move up and down, so that one of the material trays 104 in the material frame is raised and lowered to the corresponding height of the material removal station. The material frame lifting mechanism 101 can drive the entire material frame 100, including the material trays 104 arranged vertically inside, to achieve lifting and lowering movement. During the lifting and lowering process, the material frame 100 and the material trays 104 maintain stable vertical movement without corresponding horizontal displacement.

[0072] The tray feeding mechanism 102 brings the tray 104 out of the component material warehouse 159 in a progressive manner, so that the rear cover components on the tray are sent to the waiting station in turn; the tray feeding mechanism 102 is on the feeding side of the material frame 100, and the tray feeding mechanism 102 includes a progressive workbench 108 and a progressive driver 109, and a waiting station is set on the progressive workbench; the material frame lifting mechanism 101 drives the material frame 100 to move up and down, so that one of the trays 104 is flush with the height of the progressive workbench 108; the progressive driver 109 brings the tray 104 flush with the height of the progressive workbench 108 out of the material frame 100 through the feeding side, and gradually moves the tray 104 toward the progressive workbench 108, so that a part of the two rear cover components on the tray 104 are at the waiting station.

[0073] A loading station is located on one side of the progressive workbench 108. The loading station has a loading trough 150 for placing two rear cover assemblies. The loading trough 150 is used to receive rear cover assemblies from the waiting station. The picking mechanism 103 is located above the progressive workbench 108. The picking mechanism 103 picks and places rear cover assemblies from the waiting station onto the loading station, placing the two rear cover assemblies in a front-to-back arrangement. After the rear cover assemblies on the waiting station on the material tray 104 are removed, the progressive driver 109 drives the material tray 104 on the progressive workbench 108 to move progressively, allowing the rear cover assemblies on the tray 104 to move progressively to the waiting station. By adopting progressive feeding and coordinating the lifting and lowering of multiple trays within the material frame, tray replacement can be achieved without stopping the machine.

[0074] See Figure 8As shown, in this application, the material frame 100 includes a base 111, a top connecting portion 112, and support portions 113 fixedly arranged on both sides above the base 111; the base 111 is arranged horizontally, and the two support portions 113 face each other to form a vertical arrangement. The lower outer side surfaces of the support portions 113 are fixedly connected to the upper surface of the base 111 via a connecting seat 114 having a reinforcing structure 110; the above-mentioned discharge space is formed between the inner sides of the two support portions 113, above the base 111, and below the top connecting portion 112; the top connecting portion 112 is located above the two support portions 113, forming a fixed connection between the tops of the two support portions 113, making the structure of the material frame 100 more solid; the discharge space is a square space with the same size from the filling side to the feeding side. Space is provided in the discharge space for the material trays 104 to be distributed up and down.

[0075] In this application, in order to reduce the material and weight of each component and reduce the driving force of the material frame lifting mechanism 101, a plurality of through holes 115 are distributed on the base 111 and / or the top connecting part 112 and / or the supporting part 113, penetrating the inner and outer surfaces of each.

[0076] In the present application, a number of slots 116 arranged horizontally are respectively provided on the upper and lower height directions of the inner side surfaces of the two supporting parts 113. The slots 116 extend to both ends of the supporting parts 113 and pass through the two ends of the corresponding supporting parts 113. The slots 116 of corresponding heights on the two supporting parts 113 constitute a discharge station for the insertion of the feed tray 104. One feed tray 104 is inserted into one discharge station. After the feed tray is installed in the discharge station, there is a certain height interval between the upper and lower adjacent feed trays 104 to avoid interference caused by movement; after the feed tray 104 is inserted into the installation station, the upper surface of the feed tray 104 is arranged in a horizontal direction, and the upper and lower adjacent feed trays 104 are also arranged parallel to each other; in order to facilitate the insertion of the feed tray 104 into the discharge station, the end and tail of the slot are set with a flared opening 117, that is, the opening size of the end and tail of the slot is conical, and the middle position of the slot is the same size. The slots on the two supporting parts 113 with the same height are arranged facing each other and are symmetrically arranged with respect to the center position between the two supporting parts 113 .

[0077] See Figure 9As shown, in the present application, the material tray 104 includes a material placement portion 118, a portion of the upper surface of the material placement portion 118 is arranged with several assembly stations of one type of rear cover assembly, and another portion is arranged with several assembly stations of another type of rear cover assembly. The assembly station is a placement slot opened on the upper surface of the material tray 104 for placing the assembly. After the rear cover assembly is placed in the corresponding placement slot, a portion of the rear cover assembly is exposed from the placement slot for subsequent clamping; the assembly stations of adjacent different rear cover assemblies are arranged side by side in a flush manner, that is, one portion in a row is one type of rear cover assembly (rain plug), and the other portion is another type of rear cover assembly (rear cover), and the number of the two types of rear cover assemblies in a row is the same; both sides of the material placement portion are at the discharge station, and are supported by the lower wall of the slot and blocked by the bottom surface of the slot.

[0078] A drive unit 119 is fixedly mounted at one end of the loading section, and a linkage unit 120 is fixedly mounted at the other end, which is linked to the progressive driver 109. The drive unit 119 is used to push the material tray 104 into the material discharging station in the material frame 100, or to facilitate the extraction of the material tray 104 from the material discharging station in the material frame 100. In this application, the drive unit 119 is configured as a handle structure to facilitate operator use; the linkage unit 120 is a structure that can connect with the progressive driver 109 to form a transmission connection, or disconnect and lose the transmission connection. The details will be described in detail below.

[0079] See Figure 6 、 7 As shown in Figures 1 and 11, in the present application, the progressive workbench 108 is located on the feeding side of the material frame 100. The progressive workbench 108 includes a first carrier 121 and a second carrier 122 that are arranged at intervals and in a horizontal direction. The progressive driver 109 is arranged horizontally below the first carrier 121 and the second carrier 122. The first carrier 121 and the second carrier 122 are supported and fixed below by an I-shaped bracket 123, so that the first carrier 121 and the second carrier 122 are at a certain height; the upper surface of the first carrier 121 and the upper surface of the second carrier 122 are shaped The bottom surface of the feed tray 104 slides and forms a supporting surface 124 for supporting the feed tray 104. The length of the supporting surface 124 is greater than the length of the material frame 100. The supporting surface formed by the upper surface of the first carrier and the supporting surface formed by the upper surface of the second carrier 122 are on the same horizontal plane. The height of the supporting surface formed by the two carriers is not lower than the height of the uppermost feed tray 104 in the material frame 100, and is at least flush with the material discharge work of the uppermost feed tray 104 in the material frame 100, so as to ensure that all feed trays 104 in the material frame 100 can be delivered to the supporting surface position.

[0080] In the present application, to prevent the material tray 104 from deflecting on the supporting surface, upwardly extending limiters 125 are fixedly installed on the outer sides of the upper surfaces of the first carrier and the second carrier 122. The distance between the inner sides of the two limiters 125 is greater than the width of the material tray 104. The inner sides of the two limiters form a stop on the two side surfaces of the material tray 104. The material tray 104 can only move back and forth in the driving direction of the progressive driver 109 without deflecting, thereby ensuring the position accuracy of the material tray 104 when it moves to the progressive workbench 108. A limit cover plate 154 is fixedly installed above the limiter, extending above the supporting surface to limit the upward movement of the material tray 104.

[0081] In the present application, the supporting surface is composed of a bearing sliding surface 126 and a step surface 127 lower than the bearing sliding surface. The bottom side of the material tray 104 mainly has a bearing sliding surface to form a sliding fit to reduce the contact area between the supporting surface and the bottom surface of the material tray 104, thereby reducing the movement resistance of the material tray 104; and the end of the supporting surface close to the feeding side of the material frame 100 is formed with a downward inclined surface 128 to guide the material tray 104 to smoothly enter the supporting surface. The lowest position of the inclined surface does not exceed the lowest position of the expansion of the slot, or the lowest position of the inclined surface is flush with the lowest position of the expansion of the slot.

[0082] In the present application, the driving end of the progressive driver 109 cooperates with the linkage portion 120 on the material placement portion to provide power for the movement of the material tray 104. The progressive driver 109 and the linkage portion 120 can be combined to form a transmission or separated to lose transmission. Specifically, the progressive driver 109 includes a progressive motor 129, a progressive screw, and a drive platform 130. The progressive motor 129 is connected to one end of the progressive screw in a transmission manner. The drive platform 130 forms a threaded transmission with the progressive screw. The progressive motor 129 drives the drive platform 130 to move through the progressive screw.
