Description

Technical Field

[0001] This invention relates to the field of wire harness manufacturing technology, and more specifically to an automatic feeding device for high-voltage wire harness assemblies for new energy vehicles. Background Technology

[0002] High-voltage wiring harnesses for new energy vehicles can be configured for internal and external wiring connections according to different voltage levels. They are primarily used for signal distribution within the power distribution box, efficiently and effectively transmitting electrical energy, and shielding against external signal interference. High-voltage wiring harnesses form the neural network of the high-voltage system in new energy vehicles. The manufacturing process for high-voltage wiring harnesses involves a series of steps, including wire cutting, feeding rear covers and rain plugs, wire threading, stripping the outer insulation, and cutting the shielding mesh. Currently, the feeding of high-voltage wiring harness rear covers and rain plugs is mostly done manually, one by one, at the feeding station. This is inefficient, labor-intensive, and cannot meet the requirements of automated and standardized wiring harness production. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this invention is to provide an automatic feeding device for high-voltage wiring harness components in new energy vehicles that reduces the workload of workers and automatically achieves feeding.

[0004] The technical solution for implementing the present invention is as follows:

[0005] An automatic feeding device for high-voltage wiring harness components for new energy vehicles includes a material frame, a material frame lifting mechanism, a progressive working mechanism, and a material picking mechanism.

[0006] One side of the material frame is the filling side, and the other side is the feeding side. The inside of the material frame is a discharge space that is connected to the filling side and the feeding side. The discharge space has a vertical height, and at least two discharge stations are set in the vertical height direction within the discharge space.

[0007] A material tray is placed in the material feeding station inside the material frame. The material tray is placed horizontally into the material feeding station from the side of the filler. There are two different high-voltage wire harness assembly placement stations on the upper surface of the material tray. Each assembly placement station includes multiple rows of assembly stations arranged on the upper surface of the material tray.

[0008] The material frame lifting mechanism is located on the outside of the material frame, which drives the material frame to lift and lower, so that the material tray is raised and lowered to the corresponding height;

[0009] The progressive working mechanism is located on the feeding side of the material frame. The progressive working mechanism includes a progressive worktable and a progressive driver. A material-retrieving station is set on the progressive worktable. The material frame lifting mechanism drives the material frame to move up and down, so that one of the material trays is level with the height of the progressive worktable. The progressive driver brings the material tray, which is level with the height of the progressive worktable, out of the material frame, through the feeding side, and gradually moves it toward the progressive worktable, so that a portion of the two high-voltage wire harness assemblies on the material tray is in the material-retrieving station.

[0010] A loading station is set on one side of the progressive workbench, and a picking mechanism is set above the progressive workbench. The picking mechanism picks up the high-voltage wire harness assembly that is in the picking station and places it into the loading station.

[0011] The progressive drive also drives the tray on the progressive worktable to move progressively, so that the high-voltage wire harness assembly on the tray moves progressively to the pick-up station.

[0012] In this application, the material frame includes a base, a top connecting part, and support parts fixedly disposed on both sides above the base; the base is arranged horizontally, and the two support parts face each other to form a vertical arrangement, forming the aforementioned material feeding space between the inner sides of the two support parts and the top of the base; the top connecting part is located above the two support parts, and the tops of the two support parts are fixedly connected.

[0013] The inner sides of the two support parts are provided with several horizontally arranged slots in the vertical direction. The slots pass through the two ends of the corresponding support parts. The slots at the corresponding heights on the two support parts form a feeding station for inserting the feeding tray. After the feeding tray is inserted into the feeding station, the upper surface of the feeding tray is arranged in the horizontal direction. The ends and tails of the slots are flared.

[0014] In this application, the material tray includes a material placement section. A portion of the upper surface of the material placement section is arranged with several component stations for one type of high-voltage wire harness assembly, and another portion is arranged with several component stations for another type of high-voltage wire harness assembly. The component stations of adjacent high-voltage wire harness assemblies are arranged side by side and flush. The two sides of the material placement section are inserted into the material release stations.

[0015] A drive unit is fixedly installed at one end of the material feeding section, and a linkage unit that is linked with the progressive drive is fixedly installed at the other end.

[0016] In this application, the progressive worktable is located on the feeding side of the material frame. The progressive worktable includes a first platform and a second platform arranged at intervals. The progressive driver is located between the first platform and the second platform. The upper surface of the first platform and the upper surface of the second platform form a support surface that slides on the bottom surface of the feeding tray and supports the material tray. The length of the support surface is greater than the length of the material frame. The upper surface of the first platform and the upper surface of the second platform are on the same horizontal plane.

[0017] An upwardly extending limiting part is fixedly provided on the outer side of the upper surface of the first platform and the outer side of the upper surface of the second platform, respectively, and the distance between the inner sides of the two limiting parts is greater than the width of the material tray.

[0018] The drive end of the progressive drive cooperates with the linkage on the feeding section to provide power for the movement of the material tray.

[0019] In this application, the progressive driver includes a progressive motor, a progressive lead screw, and a drive platform. The progressive motor is connected to one end of the progressive lead screw, and the drive platform is connected to the progressive lead screw. The progressive motor drives the drive platform to move through the progressive lead screw. A connection structure that engages and disengages with the linkage part is provided on the drive platform.

[0020] In this application, the linkage part includes a fixed connection part fixedly disposed at the middle position of the end of the material feeding part, and an opening part integrally disposed with the fixed connection part. The opening part is an open end on one side, and the opening direction of the opening part intersects with the movement direction of the material tray.

[0021] The connection structure includes a connection driver mounted on a drive platform and a connection motion part driven by the connection driver. A transmission part is fixedly provided on the connection motion part. The connection driver drives the connection motion part to move back and forth, so that the transmission part on the connection motion part extends into the opening to form a transmission engagement, or so that the transmission part separates from the opening.

[0022] In this application, the material handling mechanism includes a gantry bracket, a material handling translation driver, a material handling translation stage, a material handling lifting driver, a material handling lifting stage, and a material handling claw;

[0023] The gantry bracket spans across the material pick-up station and the material loading station; the material pick-up translation driver is located on the top of the gantry bracket, and the material pick-up translation table is slidably located on the top of the gantry bracket. The material pick-up translation driver and the material pick-up translation table form a transmission connection to drive the material pick-up translation table to reciprocate in the horizontal direction.

[0024] The material handling lifting driver is set on the material handling translation platform. The material handling lifting platform is driven by the material handling lifting driver to drive the material handling lifting platform to reciprocate and lift in the vertical direction. The material handling claw is installed on the material handling lifting platform. The material handling claw picks up the high-voltage wire harness assembly on the waiting station and places it on the loading station.

[0025] In this application, the loading station includes a loading driver, a loading platform, a station driver, and a station carrier;

[0026] The loading platform is mounted on the loading driver, which drives it to reciprocate horizontally; the reciprocating direction of the loading platform driven by the loading driver is the same as the direction of movement of the material tray.

[0027] The workstation driver is mounted on the loading platform and moves along with the loading platform;

[0028] The workstation driver is a dual-head telescopic driver;

[0029] The workstation carrier is provided in pairs, which are respectively assembled on the telescopic drive end of the workstation driver. The workstation driver drives the pair of workstation carriers to form a disengagement or engagement action; the disengagement and engagement direction of the workstation carriers is arranged perpendicular to the movement direction of the loading platform.

[0030] A loading and placement trough for two types of high-voltage wire harness assemblies is formed between a pair of workstation carriers, arranged one in front of the other.

[0031] The station driver drives the station carrier to separate or rejoin, thereby changing the size of the loading slots for the two types of high-voltage wire harness assemblies.

[0032] In this application, the material frame lifting mechanism includes a lifting drive motor, a lifting drive screw, and a driving lifting block located on one side of the material frame. The lifting drive motor is connected to the lifting drive screw, and the driving lift screw and the driving lifting block are connected by a threaded drive. The driving lifting block is fixedly mounted on one side outside the material frame. The lifting drive motor drives the material frame to achieve lifting movement, so as to drive the material trays in the material frame to be level with the height of the progressive worktable one by one.

[0033] In this application, the base and / or the top connecting part and / or the support part are provided with a plurality of through holes that penetrate their respective inner and outer surfaces.

[0034] The technical solution of this application involves first placing two types of high-voltage wire harness assemblies (rain plugs and back covers) onto the component placement station of the material tray; then inserting the material tray from the filling side of the material frame into the feeding station of the material frame; raising the material frame via a lifting mechanism to bring the material tray to the same height as the advancing worktable; and then moving the material tray from the feeding side of the material frame towards the advancing worktable via a advancing driver, so that the two types of high-voltage wire harness assemblies at the frontmost row of the material tray are in the waiting-to-retrieve station; finally, the picking mechanism picks up the two types of high-voltage wire harness assemblies from the waiting-to-retrieve station and places them into the loading station. This invention enables the automatic transport of two types of high-voltage wire harness assemblies (rain plugs and back covers) to the loading station, requiring only the operator to load the wire harness assemblies into the material tray, reducing workload and improving automation; furthermore, by employing progressive feeding and coordinating with the lifting of multiple material trays within the material frame, material tray replacement can be achieved without stopping the machine.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1As shown in Figure 8, the automatic feeding device for high-voltage wiring harness components of new energy vehicles includes a material frame 100, a material frame lifting mechanism 101, a progressive working mechanism 102, and a material picking mechanism 103. One side of the material frame 100 is a filling side, and the other side is a feeding side. The interior of the material frame 100 is a feeding space that communicates with the filling side and the feeding side. The feeding space has a vertical height, and multiple upper and lower feeding stations are arranged in the vertical direction within the feeding space. Each feeding station in the material frame 100 contains material. The tray 104 is placed horizontally into the feeding station from the filling side; the tray 104 is inserted into the feeding station from the filling side of the material frame 100. After the tray 104 is installed in the feeding space, it forms an upper and lower layer arrangement. In use, the tray 104 can be moved out of the material frame 100 from the feeding side or from the filling side of the material frame 100. The specific time when the tray 104 is inserted into and removed from the material frame 100 will be explained in the following usage process.

[0046] Two different high-voltage wire harness assemblies are provided on the upper surface of the tray 104. Each component placement station 105 includes multiple rows of component stations arranged on the upper surface of the tray 104. One component station is used to place the rain plug 106 in the high-voltage wire harness assembly, and the other component station is used to place the back cover 107 in the high-voltage wire harness assembly. The two high-voltage wire harness assemblies are placed together on one tray 104 and can be transported to the corresponding positions at the same time.

[0047] The material frame lifting mechanism 101 is located on the outside of the material frame 100, which drives the material frame 100 to lift and lower, so that the material tray 104 is raised and lowered to the corresponding height. The material frame lifting mechanism 101 can drive the entire material frame 100, including the material tray 104 arranged vertically inside, to achieve lifting and lowering. During the lifting and lowering process, the material frame 100 and the material tray 104 maintain stable vertical movement, while there is no corresponding displacement in the horizontal direction.

[0048] The advancing mechanism 102 is located on the feeding side of the material frame 100. The advancing mechanism 102 includes an advancing worktable 108 and an advancing driver 109. A material-retrieving station is provided on the advancing worktable 108. The material frame lifting mechanism 101 drives the material frame 100 to move up and down, so that one of the material trays 104 is level with the height of the advancing worktable 108. The advancing driver 109 carries the material tray 104, which is level with the advancing worktable 108, out of the material frame 100 via the feeding side, and gradually moves the material tray 104 towards the advancing worktable 108, so that... A portion of the two types of high-voltage wire harness assemblies on the material tray 104 are in the waiting-to-receive station; a loading station is provided on one side of the progressive worktable 108, and a picking mechanism 103 is provided above the progressive worktable 108. The picking mechanism 103 picks up the high-voltage wire harness assemblies in the waiting-to-receive station and places them in the loading station; after the high-voltage wire harness assemblies in the waiting-to-receive station on the material tray 104 are picked up, the progressive driver 109 also drives the material tray 104 on the progressive worktable 108 to move progressively, so that the high-voltage wire harness assemblies on the material tray 104 progressively move to the waiting-to-receive station.

[0049] The working process of this invention is as follows: First, two types of high-voltage wire harness assemblies (rain plugs and back covers) are placed on the assembly placement station 105 on the material tray 104. Half of the material tray 104 is a rain plug assembly placement station, and the other half is a back cover assembly placement station. The number of the two types of assemblies is the same, and the number arranged in each row is also the same. The material tray 104 is then inserted horizontally from the filler side of the material frame 100 into the corresponding placement station in the material placement space, so that the two types of high-voltage wire harness assemblies are above the material tray 104. The material frame lifting mechanism 101 drives the assembly to complete the process. The material frame 100 rises, causing the uppermost material tray 104 to rise to the same height as the advancing worktable 108. A connection is formed between the tray 104 on the feeding side of the material frame 100 and the advancing driver 109. The advancing driver 109 moves the tray 104 from the feeding side of the material frame 100 toward the advancing worktable 108, placing the two high-voltage wire harness assemblies in the frontmost row of the tray 104 at the waiting-to-be-picked position. The picking mechanism 103 then picks up the two high-voltage wire harness assemblies from the waiting-to-be-picked position. At the loading station, materials are retrieved in sets of one rain plug and one back cover. After the high-voltage wire harness assemblies at the subsequent loading station are used, materials are retrieved sequentially from the waiting-to-retrieve station. Once both types of high-voltage wire harness assemblies at the retrieval station are retrieved, the advance driver 109 advances the next row of two types of high-voltage wire harness assemblies to the waiting-to-retrieve station for retrieval, until all components on the tray 104 are used. The advance driver 109 then pushes the tray 104 back into the material frame 100. After pushing it back into the material frame 100, the delivery... The feed driver 109 separates from the material frame 100, losing its transmission. The material frame lifting mechanism 101 raises the next layer of material tray 104 in the material frame 100 to a position flush with the advancing station, and then advances the material tray 104 to the advancing worktable 108 via the advancing driver 109 to perform the same material picking operation as described above. When the material tray 104 in the material frame 100 is empty, the material frame 100 can be removed from the filling side, the high-voltage wire harness assembly can be added to the material tray 104, and then inserted into the material frame 100. Based on this, it is possible to automatically transport two types of high-voltage wire harness assemblies to the loading station. The operator only needs to load the wire harness assembly into the material tray 104, thereby improving the level of automation.

[0050] One embodiment of this application: The material frame 100 includes a base 111, a top connecting portion 112, and support portions 113 fixedly disposed on both sides above the base 111; the base 111 is arranged horizontally, and the two support portions 113 are arranged vertically facing each other. The lower outer surface of the support portion 113 is fixedly connected to the upper surface of the base 111 by a connecting seat 114 with a reinforcing structure 110; the aforementioned material feeding 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, fixing the tops of the two support portions 113 together, making the structure of the material frame 100 more robust; the material feeding space is a square space with consistent dimensions from the filling side to the feeding side. Space is provided within the material feeding space to allow for the vertical distribution of the material tray 104.

[0051] In one embodiment of this application, in order to reduce the material usage 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 support part 113, which penetrate their respective inner and outer surfaces.

[0052] In one embodiment of this application: several horizontally arranged slots 116 are respectively provided on the inner side of the two support parts 113 in the vertical direction. The slots 116 extend to both ends of the support parts 113 and pass through the corresponding ends of the support parts 113. The slots 116 at corresponding heights on the two support parts 113 form a feeding station for inserting the feeding tray 104. One tray 104 is inserted into one feeding station. After the tray is inserted into the feeding station, there is a certain height gap between the upper and lower adjacent trays 104 to avoid interference caused by movement. After the tray 104 is inserted into the insertion station, the upper surface of the tray 104 is arranged in the horizontal direction, and the upper and lower adjacent trays 104 are also arranged in parallel to each other. In order to facilitate the insertion of the tray 104 into the feeding station, the ends and tails of the slots are flared 117, that is, the opening size of the ends and tails of the slots is tapered, and the middle position of the slots is the same size. The slots on the two support parts 113 are arranged facing each other with the same height, and are arranged symmetrically with the center position between the two support parts 113.

[0053] One embodiment of this application: The material tray 104 includes a material placement section 118. A portion of the upper surface of the material placement section 118 is arranged with several component stations for one type of high-voltage wire harness assembly, and another portion is arranged with several component stations for another type of high-voltage wire harness assembly. The component stations are placement slots opened on the upper surface of the material tray 104 for placing the components. After the high-voltage wire harness assembly is placed into the corresponding placement slot, a portion of the high-voltage wire harness assembly is exposed in the placement slot for subsequent clamping. The component stations of adjacent different high-voltage wire harness assemblies are arranged side by side and flush, that is, a portion of a row contains one type of high-voltage wire harness assembly (rain plug), and another portion contains another type of high-voltage wire harness assembly (back cover), and the number of the two types of high-voltage wire harness assemblies in a row is the same. The two sides of the material placement section are located at the material release station and are supported by the lower wall of the slot and blocked by the bottom surface of the slot.

[0054] A drive unit 119 is fixedly provided at one end of the material placement section, and a linkage unit 120, which is linked with the progressive drive 109, is fixedly provided at the other end. The drive unit 119 is used to push the material tray 104 into the material feeding station in the material frame 100, or to facilitate the removal of the material tray 104 from the material feeding station in the material frame 100. In this application, the drive unit 119 is configured as a handle structure for easy use by the operator. The linkage unit 120 is a structure that can be connected with the progressive drive 109 to form a transmission engagement, or can be separated to lose the transmission engagement, which will be described in detail below.

[0055] In one embodiment of this application: a progressive worktable 108 is located on the feeding side of the material frame 100. The progressive worktable 108 includes a first platform 121 and a second platform 122 arranged horizontally at intervals. A progressive driver 109 is arranged horizontally below the first platform 121 and the second platform 122. The lower parts of the first platform 121 and the second platform 122 are supported and fixed by an I-shaped bracket 123, so that the first platform and the second platform 122 are at a certain height. The upper surface of the first platform and the upper surface of the second platform 122 are shaped... The bottom surface of the feeding tray 104 slides and forms a support surface 124 that supports the tray 104. The length of the support surface 124 is greater than the length of the material frame 100. The support surface formed by the upper surface of the first platform and the support surface formed by the upper surface of the second platform 122 are on the same horizontal plane. The height of the support surface formed by the two platforms is not lower than the height of the uppermost tray 104 in the material frame 100, and is at least flush with the material feeding operation of the uppermost tray 104 in the material frame 100, so as to ensure that all trays 104 in the material frame 100 can be fed into the support surface position.

[0056] In one embodiment of this application: to prevent the tray 104 from shifting on the support surface, upwardly extending limiting portions 125 are fixedly provided on the outer side of the upper surface of the first platform and the outer side of the upper surface of the second platform 122, respectively. The distance between the inner sides of the two limiting portions 125 is greater than the width of the tray 104. The two sides of the tray 104 are respectively stopped by the inner sides of the two limiting portions. The tray 104 only moves back and forth in the driving direction of the progressive driver 109 and will not deviate, so as to ensure the positional accuracy of the tray 104 when it moves onto the progressive worktable 108. In addition, a limiting cover plate 154 is fixedly installed above the limiting portions, and the limiting cover plate 154 extends above the support surface to restrict the upward movement of the tray 104.

[0057] One embodiment of this application: see [link] Figure 7 As shown, the support surface is composed of a sliding surface 126 and a stepped surface 127 lower than the sliding surface. The bottom side of the material tray 104 mainly has a sliding fit with the sliding surface to reduce the contact area between the support surface and the bottom surface of the material tray 104 and reduce the moving resistance of the material tray 104. The end of the support surface near the feeding side of the material frame 100 is provided with a downward inclined surface 128 to guide the material tray 104 to smoothly enter the support surface. The lowest position of the inclined surface does not exceed the lowest position of the slot flare, or the lowest position of the inclined surface is flush with the lowest position of the slot flare.

[0058] One embodiment of this application: see [link] Figure 3 , 7 As shown, the driving end of the progressive driver 109 cooperates with the linkage part 120 on the material feeding part to provide power for the movement of the material tray 104. The progressive driver 109 and the linkage part 120 can be engaged to form a transmission or disengaged to lose the transmission. Specifically, the progressive driver 109 includes a progressive motor 129, a progressive lead screw, and a drive platform 130. The progressive motor 129 is connected to one end of the progressive lead screw, and the drive platform 130 forms a threaded transmission engagement with the progressive lead screw. The progressive motor 129 drives the drive platform 130 to move through the progressive lead screw. A connection structure 131 that engages and disengages with the linkage part 120 is provided on the drive platform 130. The linkage 120 includes a fixed connection 132 fixedly disposed at the middle position of the end of the material placement part, and an opening 133 integrally disposed with the fixed connection 132. The opening 133 is open on one side, and the opening direction of the opening intersects the movement direction of the material tray 104. The opening is U-shaped groove, and the entrance of the opening is a conical guide surface 134 to facilitate the introduction of the component that mates with the opening into the opening.

[0059] One embodiment of this application: The connecting structure 131 includes a connecting driver 135 mounted on a drive platform 130, and a connecting motion part 136 driven by the connecting driver 135. A transmission part 137 is fixedly disposed on the connecting motion part 136 and arranged in an oriented manner. The connecting driver 135 drives the connecting motion part 136 to reciprocate, causing the transmission part 137 on the connecting motion part 136 to extend into the opening to form a transmission engagement, or causing the transmission part 137 to separate from the opening. The connecting driver 135 is a drive cylinder with a slide table. The connecting motion part 136 is fixedly mounted on the slide table of the drive cylinder. When the drive cylinder is working, it drives the connecting motion part 136 to slide through the slide table. One side of the connecting motion part 136 extends outward into an extension part 138.
