Description

Technical Field

[0001] This utility model belongs to the technical field of rubber wiper blade spray coating, and in particular relates to a rubber wiper blade spray coating transfer device. Background Technology

[0002] Rubber wiper blades are wiper devices, mostly installed on automobiles, used to wipe rainwater off the windshield. Therefore, with prolonged use and aging of the rubber wiper blades, the wear grade gradually increases, leading to a widening gap between the wiper blade and the windshield, thus reducing its wiping ability. Furthermore, the corrosive effects of rainwater, such as acid rain, further degrade the performance of the rubber wiper blades.

[0003] Therefore, in order to improve the performance of rubber wiper blades, the most common practice is to spray a protective coating on the wiper blades. The performance of the wiper blades can be improved by spraying a protective coating, including wear resistance, corrosion resistance, and aging resistance.

[0004] During processing, wiper blade blanks are laid flat on a frame-shaped structure, and then conveyed to a spraying device via a conveyor. After spraying, they are sent to a drying device for drying. After drying, the flat frame and wiper blades are simultaneously unloaded from the same conveyor to another conveyor for further processing, including cooling and cleaning.

[0005] However, because the wiper blades are laid flat on the laying frame, and the temperature of both the wiper blades and the laying frame is quite high after drying, it is difficult to transfer them to another conveyor. Furthermore, the wiper blades must be kept flat on the laying frame throughout the processing. Currently, the workshop manually transfers the laying frame and wiper blades, which not only carries a high operational risk due to the excessively high temperature of the laying frame and wiper blades, but also easily disrupts the flatness of the wiper blades on the laying frame during the transfer process. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a rubber wiper strip spray coating transfer device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rubber wiper strip coating transfer device includes a transfer mechanism that transfers a flat frame containing stacked rubber wiper strips.

[0009] The material transfer mechanism includes rails spaced apart on both sides, and a movable material transfer component is arranged between the rails. The material transfer component includes vertical frames spaced apart on both sides, and an upper lifting rod and a lower positioning rod that cooperate with each other are installed between the vertical frames; the upper lifting rod is raised and lowered by a lifting structure.

[0010] The upper lifting rod and the lower positioning rod are connected at a height by several clamping rods that hold the flat frame;

[0011] The material transfer mechanism also includes a rotating structure for driving the vertical frame to rotate, and a moving structure for driving the material transfer assembly to move horizontally.

[0012] Preferably, the upper and lower ends of the vertical frame are respectively provided with an upper sliding opening and a lower sliding opening;

[0013] The two ends of the upper lifting rod and the lower positioning rod are slidably connected to the upper sliding port and the lower sliding port, respectively;

[0014] An upper sliding rod and a lower sliding rod are fixedly connected to the upper sliding opening and the lower sliding opening respectively, and the two ends of the upper lifting rod and the lower positioning rod are slidably connected to the upper sliding rod and the lower sliding rod respectively.

[0015] A pair of positioning nuts are threaded onto the lower sliding rod, and the positioning nuts are positioned at the top and bottom of the lower positioning rod.

[0016] Preferably, a spring is sleeved on the upper sliding rod, and the two ends of the spring are respectively fixedly connected to the bottom of the upper lifting rod and the bottom of the upper sliding opening;

[0017] The lifting structure includes cylinders spaced apart on the front and rear sides. The piston rod of the cylinder is fixed to the top of the upper lifting rod, and a cylinder support for fixing and installing the cylinder is fixedly connected to the top of the vertical frame.

[0018] Preferably, the rotating structure includes a fixed support seat rotatably connected to the vertical frame, and a rotating shaft is fixedly connected to the lower end of the vertical frame, the rotating shaft being rotatably connected to the fixed support seat;

[0019] A drive motor is mounted on a fixed bracket on one side, and the output end of the drive motor is mounted on a rotating shaft.

[0020] Preferably, the movable structure includes a drive bracket fixedly mounted on a fixed support base, a roller motor mounted on the drive bracket base, and rollers mounted on the roller motor, with the rollers rolling on top of the track.

[0021] Preferably, a long track groove for limiting rollers is provided on the top outer side of the track, and the rollers roll in the track groove.

[0022] Preferably, the bottom of the drive bracket is fixedly connected to a slide block that is slidably connected to the track, and the top inner side of the track is integrally formed with a sliding rail, on which a sliding groove adapted to the slide block is provided.

[0023] Preferably, the longitudinal cross-sectional shape of the groove and the slide block is T-shaped.

[0024] Preferably, the outer end of the clamping rod is integrally formed with a flat shovel.

[0025] This utility model has the following beneficial effects:

[0026] 1. During the operation, when the material transfer component clamps the flat frame and wiper strip from one side of the conveyor in the manner described above, the material transfer component moves to the position of the other side of the conveyor and lowers the flat frame and wiper strip. At this time, driven by the rotating structure, the vertical frame, the upper lifting rod, the lower positioning rod, the flat frame and the clamped wiper strip are simultaneously flipped to the position on the other conveyor.

[0027] The above method enables the automatic transfer of the flat frame and the wiper blades placed on it during the transfer process. This method effectively avoids various drawbacks of traditional manual transfer, such as high-temperature burns and damage to the coating on the wiper blades that have not cured under high temperatures.

[0039] Example 1

[0040] like Figure 1-5 As shown, a rubber wiper strip coating transfer device includes a transfer mechanism that transfers the flat frame 1 on which the rubber wiper strips are stacked.

[0041] Specifically, during the operation, the wiper blades are laid flat on the flat frame 3, so that the wiper blades placed on the flat frame 3 are sprayed and heated in the same way during the spraying process.

[0042] During the production process, the flat frame 3-wiper strip needs to be transferred from one production line (conveyor 2) to another production line (conveyor 2). Conveyor 1 is a roller conveyor used in the production workshop, that is, conveyor 2 has multiple rotating rollers, and the flat frame 3 is supported on the rollers and driven to move forward by the rotation of the rollers.

[0043] Therefore, in order to solve the technical problem of difficult transfer, the above-mentioned transfer mechanism 1 includes rails 1 arranged at intervals on both sides (the rails 1 are arranged between the conveyors, and according to the existing method, the height of the rails 1 is adjusted to correspond to the height of the conveyors by installing a rail support frame at the bottom of the rails 1).

[0044] A movable material transfer assembly is provided between the tracks 1. The material transfer assembly includes vertical frames 16 spaced apart on the front and rear sides. An upper lifting rod 15 and a lower positioning rod 14 are installed between the vertical frames 16. The upper lifting rod 15 is raised and lowered by a lifting structure.

[0045] Specifically, the upper and lower ends of the vertical frame 16 are respectively provided with an upper sliding port and a lower sliding port, and the front and rear ends of the corresponding upper lifting rod 15 and lower positioning rod 14 are slidably connected in the upper sliding port and the lower sliding port, respectively.

[0046] Meanwhile, an upper sliding rod 151 and a lower sliding rod are fixedly connected to the upper sliding port and the lower sliding port respectively. The two ends of the upper lifting rod 15 and the lower positioning rod 14 are slidably connected to the upper sliding rod 151 and the lower sliding rod respectively. A pair of positioning nuts 142 are threadedly connected to the lower sliding rod, and the positioning nuts 142 are positioned at the top and bottom of the lower positioning rod 14.

[0047] During operation, the distance between the upper sliding rod 151 and the lower sliding rod is adjusted according to the size and thickness of the wiper blade (blank), and the distance between the clamping rods 18 is adjusted synchronously.

[0048] The method is as follows: after loosening the positioning nut, adjust the distance between the lower positioning rod 14 and the upper lifting rod 15, and then position the positioning nut 142.

[0049] A spring 152 is sleeved on the upper sliding rod 151. The two ends of the spring 152 are fixedly connected to the bottom of the upper lifting rod 15 and the bottom of the upper sliding port, respectively. The lifting structure includes cylinders 17 spaced apart on the front and rear sides. The piston rod of the cylinder 17 is fixed to the top of the upper lifting rod 15. The top of the vertical bracket 16 is fixedly connected to a cylinder support for fixing the cylinder 17.

[0050] During operation, driven by cylinder 17, the upper lifting rod 15 descends and approaches the lower positioning rod 14. Subsequently, the lower clamping rod 18 clamps the flattening frame 3 and the wiper blade laid flat on the flattening frame 3. During the release process, with the elastic restoring force of spring 152, the upper lifting rod 15 quickly rises and returns to its original position, and the clamping rod 18 in the upper and lower positions quickly releases.

[0051] The upper lifting rod 15 and the lower positioning rod 14 are connected by several clamping rods 18 (the clamping rods 18 are rod-shaped structures) that hold the flat frame 3.

[0052] The flat frame 3 and the wiper blades laid flat on the flat frame 3 are clamped by the clamping rods 18 at the upper and lower positions.

[0053] The aforementioned material transfer mechanism 1 also includes a rotating structure for driving the vertical frame 16 to rotate, and the material transfer mechanism 1 also includes a moving structure 13 for driving the material transfer assembly to move horizontally.

[0054] During operation, the material transfer assembly clamps the flat frame 3 and the wiper blade from one side of the conveyor in the manner described above (specifically, the clamping rod 18 extends into the bottom of the flat frame 3 when the material transfer assembly moves to the lower position; therefore, to facilitate the clamping rod 18 extending into the bottom of the flat frame 3, a flat shovel 181 is integrally formed at the outer end of the clamping rod 18 to facilitate shoveling into the bottom of the flat frame 3. Since the conveyor is a roller conveyor, it is easier for the clamping rod 18 to extend into the bottom of the flat frame 3). Then, the material transfer assembly moves to the position of the other side of the conveyor and lowers the flat frame 3 and the wiper blade.

[0055] At this time, driven by the rotating structure, the vertical frame 16, the upper lifting rod 15, the lower positioning rod 14, the flat frame 3, and the clamped wiper strip are simultaneously flipped to the upper part of another conveyor, and then the clamping rod 18 is released (driven by cylinder 17). Subsequently, the material transfer assembly continues to move away until the clamping rod 18 is disengaged from the flat frame 3.

[0056] Specifically, the rotating structure includes a fixed support base 191 rotatably connected to the vertical bracket 16 (in conventional arrangements, the fixed support base 191 is equipped with a suitable bearing). A rotating shaft is fixedly connected to the lower end of the vertical bracket 16, and the rotating shaft is rotatably connected to the fixed support base 191. Simultaneously, a drive motor 19 is mounted on the rear fixed support base 191, and the output end of the drive motor 19 is mounted on the rotating shaft. In conventional arrangements, the bottom of the drive motor 19 is fixedly mounted on the top of the fixed support base 191.

[0057] Example 2

[0058] like Figure 1-5As shown, in this embodiment, based on the structure of embodiment 1, the above-mentioned movable structure 13 includes a drive bracket 131 that is fixedly installed on the fixed bracket 191. A roller motor 132 is installed on the drive bracket 131, and a roller 133 is installed on the roller motor 132. The roller 133 rolls on the top of the track 1.

[0059] Correspondingly, in order to improve the stability of movement, a long track groove for limiting rollers 133 is opened on the top outer side of the track 1, and the rollers 133 roll in the track groove.

[0060] The bottom of the drive bracket 131 is fixedly connected to a slide block 121 that is slidably connected to the track 1. The top inner side of the track 1 is integrally formed with a sliding rail, and the sliding rail has a groove adapted to the slide block 121. The longitudinal cross-sectional shape of the groove and the slide block 121 is T-shaped. The slide block 121 maintains a limited sliding position during movement, thereby increasing the stability of linear motion and maintaining accurate positioning during lateral movement.

[0061] During operation, driven by the roller motor 132, the rollers move back and forth between the tracks 1 to transfer the flat frame 3 between the conveyors 2.

[0062] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
