Description

Technical Field

[0001] This utility model relates to the field of automotive rubber strip assembly, and in particular to a wiper cover rubber strip assembly tooling and clamping mechanism. Background Technology

[0002] Rubber strips need to be installed on the sides and top of the windshield wiper cover. The current assembly method is for the worker to place the rubber strip in the corresponding position and then press the rubber strip firmly onto the wiper cover using a pressure plate or roller. In this method, it is difficult for the worker to maintain a consistent force during the pressing process. Therefore, some rubber strips may be pressed firmly while others are not, which affects the assembly quality of the rubber strips.

[0003] CN2015207197491 discloses a tooling for assembling vehicle sunroof sealing strips. This tooling includes a working mechanism, a first handle, and a second handle interconnected by a connecting assembly. The first handle, through the connecting assembly, causes the working mechanism to press against the sealing strip, while the second handle, also through the connecting assembly, causes the working mechanism to roll along the extension direction of the sealing strip. The operator simultaneously operates the first and second handles to press the sealing strip firmly. However, this method is difficult for the operator and makes it difficult to maintain consistent pressure on the sealing strip.

[0004] The technical problem this invention aims to solve is: how to ensure that the same force is used when assembling the adhesive strips, thereby improving the assembly quality of the adhesive strips. Summary of the Invention

[0005] The main purpose of this utility model is to provide a pressing mechanism. By setting a groove on the frame and setting rollers on the moving seat, the shape of the groove matches the shape of the rubber strip mounting part. When the drive unit drives the support seat to move, the sliding part rolls in the groove and makes the rolling module move closer to or away from the wiper cover plate so that the distance between the rolling module and the rubber strip mounting part of the wiper cover plate is kept equal, thereby ensuring that the same force is used to assemble the rubber strip and improving the assembly quality of the rubber strip.

[0006] In addition, a tooling for assembling wiper cover rubber strips is also provided.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] A pressing mechanism includes a support base, a movable base, a drive module, and a rolling module for pressing an adhesive strip; the movable base is slidably connected to the support base; the rolling module is slidably connected to the movable base; the drive module is connected to the movable base; the movable base is provided with a sliding member; the sliding member contacts a groove of an external device to keep the distance between the rolling module and the wiper cover equal; the drive module is used to drive the rolling module to move toward the adhesive strip.

[0009] Preferably, the sliding element is a sliding rod or a roller.

[0010] Preferably, when the sliding element is a roller, there are multiple rollers; the bottom of the movable seat is provided with a rotatable connecting frame; the rollers are arranged in a circumferential array on the connecting frame.

[0011] Preferably, the rolling module includes a mounting base and a pressure roller; the mounting base is slidably connected to a movable base; the pressure roller is connected to the side of the mounting base near the wiper cover; a limiting plate is provided on the side of the mounting base away from the pressure roller; therefore, the limiting plate is used to control the moving distance of the pressure roller; the power output end of the drive module is connected to the mounting base.

[0012] Preferably, the mounting base has an adjusting rod on the side near the wiper cover; the pressure roller is slidably connected to the adjusting rod; the adjusting rod has a spring; one end of the spring is connected to the mounting base, and the other end is connected to the pressure roller.

[0013] Meanwhile, a wiper cover rubber strip assembly fixture is also provided, including the aforementioned pressing mechanism, frame, drive unit, and fixing unit for fixing the wiper cover onto the frame; the fixing unit is connected to the frame; the support base is slidably connected to the frame; the frame is provided with a groove; the sliding member contacts the groove to keep the distance between the rolling module and the wiper cover equal; the drive unit is used to drive the pressing mechanism to move so that the rolling module presses the rubber strip into the wiper cover.

[0014] Preferably, the groove is a blind groove or a through groove; the shape of the groove matches the shape of the rubber strip mounting part of the wiper cover.

[0015] Preferably, the drive unit includes a motor, a gear, and a rack; the movable seat is slidably connected to the support seat; the motor is connected to the support seat; the gear is connected to the power output end of the motor; the rack is connected to the frame; and the gear meshes with the rack.

[0016] Preferably, the fixing unit includes a pressing module and an overlapping boss; the overlapping boss is adapted to the shape of the wiper cover; the pressing module is used to press the wiper cover onto the overlapping boss.

[0017] Preferably, the clamping module includes a cylinder and a clamping component; the cylinder is connected to the frame; and the clamping component is connected to the power output end of the cylinder.

[0018] Compared with existing technologies, this solution has the following advantages:

[0019] The clamping mechanism in this case has a groove on the frame that matches the shape of the rubber strip mounting part. The sliding member slides in the groove. When the support seat moves along the length of the rubber strip, the sliding member also slides in the groove. Since the shape of the groove matches the shape of the rubber strip mounting part, the sliding member moves the rolling module closer to or away from the rubber strip mounting part during the movement of the groove. This keeps the distance between the rolling module and the rubber strip mounting part equal, so that the rolling module can clamp each part of the rubber strip with the same clamping force, avoiding some rubber strips not being fully clamped and improving assembly quality.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Example 1

[0027] refer to Figure 1-4A pressing mechanism includes a support base 34, a movable base 23, a drive module 22, and a rolling module 24 for pressing a rubber strip 2; the movable base 23 is slidably connected to the support base 34; the rolling module 24 is slidably connected to the movable base 23; the drive module 22 is connected to the movable base 23; the movable base 23 is provided with a sliding member 21; the sliding member 21 contacts the groove 11 of an external device to keep the distance between the rolling module 24 and the wiper cover 5 equal; the drive module 22 is used to drive the rolling module 24 to move toward the rubber strip 2.

[0028] In this embodiment, the specific working process of the pressing mechanism is as follows: the drive module 22 drives the rolling module 24 to move towards the wiper cover plate 5, and the rolling module 24 presses against the rubber strip 2 of the wiper cover plate 5. The support base 34 drives the moving base 23 to move forward, thereby driving the rolling module 24 to press the rubber strip 2 forward. During the movement of the moving base 23, the sliding member 21 moves in the groove 11, driving the moving base 23 to slide on the support base 34, so that the distance between the rolling module 24 and the rubber strip mounting part remains equal during the movement, and the rolling module 24 outputs the same pressing force.

[0029] Preferably, the sliding member 21 is a sliding rod or a roller.

[0030] In this embodiment, the slider 21 is preferably a roller. The roller is in rolling contact with the groove 11, which can reduce the wear between the slider 21 and the groove 11 and improve the service life of the slider 21 and the groove 11.

[0031] Preferably, when the sliding member 21 is a roller, there are multiple rollers; the bottom of the movable seat 23 is provided with a rotatable connecting frame 231; the rollers are arranged in a circumferential array on the connecting frame 231.

[0032] In this embodiment, there are three rollers, which are I-beam rollers. The three rollers are arranged in a circumferential array on the connecting frame 231. When the rollers roll in the groove 11, at least two rollers are in contact with the groove 11. When the rollers pass through the arc-shaped position of the groove 11, the connecting frame 231 is passively rotated, so that the rollers that are not in contact with the groove 11 become in contact with the groove 11, thereby ensuring that at least two rollers are in contact with the groove 11. This ensures that the rollers can roll smoothly in the groove 11 and avoids the moving seat 23 from shaking due to unstable connection between the rollers and the groove 11, which would affect the assembly quality of the adhesive strip 2.

[0033] Preferably, the rolling module 24 includes a mounting base 241 and a pressure roller 242; the mounting base 241 is slidably connected to the movable base 23; the pressure roller 242 is connected to the side of the mounting base 241 near the wiper cover 5; a limiting plate 243 is provided on the side of the mounting base 241 away from the pressure roller 242; therefore, the limiting plate 243 is used to control the moving distance of the pressure roller 242; the power output end of the drive module 22 is connected to the mounting base 241.

[0034] In this embodiment, a guide shaft is provided on the mounting base 241, and a linear bearing is provided on the movable base 23. The mounting base 241 and the movable base 23 are slidably connected through the cooperation of the guide shaft and the linear bearing. A limiting plate 243 is provided on the side of the mounting base 241 away from the pressure roller 242. The drive module 22 drives the mounting base 241 to move toward the adhesive strip mounting part, thereby driving the pressure roller 242 to move toward the adhesive strip mounting part and press the adhesive strip 2. When the pressure roller 242 presses the adhesive strip 2, the limiting plate 243 contacts the movable base 23, thereby preventing the drive module 22 from further driving the pressure roller 242 to move toward the adhesive strip mounting part, so as to maintain a constant pressing force during the pressing of the adhesive strip 2.

[0035] The drive module 22 is cylinder 411.

[0036] Preferably, the mounting base 241 is provided with an adjusting rod 244 on the side near the wiper cover 5; the pressure roller 242 is slidably connected to the adjusting rod 244; the adjusting rod 244 is provided with a spring 245; one end of the spring 245 is connected to the mounting base 241, and the other end is connected to the pressure roller 242.

[0037] In this embodiment, the pressure roller 242 is slidably connected to the adjusting rod 244, and the spring 245 is disposed on the adjusting rod 244. The initial position of the spring 245 is the position when the pressure roller 242 is in the middle position of the adjusting rod 244.

[0038] Since the adhesive strip 2 is curved when viewed vertically and is not a straight line, an adjusting rod 244 and a spring 245 are provided so that the pressure roller 242 can slide on the adjusting rod 244. This allows the pressure roller 242 to slide on the adjusting rod 244 according to the change in the direction of the adhesive strip 2, and thus press it tightly according to the shape of the adhesive strip mounting part.

[0039] Secondly, by setting the spring 245, part of the weight of the pressure roller 242 can be offset, so that when the pressure roller 242 moves along the rubber strip 2 and slides on the adjusting rod 244, it can move more smoothly, reduce the lateral force of the pressure roller 242 on the rubber strip 2, and improve the assembly quality.

[0040] Example 2

[0041] refer to Figure 1-4A wiper cover rubber strip assembly fixture includes a clamping mechanism as described above, a frame 1, a drive unit 3, and a fixing unit 4 for fixing the wiper cover 5 onto the frame 1; the fixing unit 4 is connected to the frame 1; the support base 34 is slidably connected to the frame 1; the frame 1 is provided with a groove 11; the sliding member 21 contacts the groove 11 to keep the distance between the rolling module 24 and the wiper cover 5 equal; the drive unit 3 is used to drive the clamping mechanism to move so that the clamping unit presses the rubber strip 2 onto the wiper cover 5.

[0042] In this embodiment, the specific workflow of the assembly fixture is as follows: the worker places the wiper cover 5 on the fixing unit 4, the fixing unit 4 presses the wiper cover 5, the drive module 22 is started, and the rolling module 24 moves toward the rubber strip 2, pressing the rubber strip 2 onto the rubber strip mounting part of the wiper cover 5. Then the drive unit 3 is started, and the drive unit 3 drives the support seat 34 to move forward, thereby driving the moving seat 23 and the rolling module 24 to move, so that the rolling module 24 can completely press the entire rubber strip 2 into the wiper cover 5.

[0043] Preferably, the groove 11 is a blind groove or a through groove; the shape of the groove 11 matches the shape of the rubber strip mounting part of the wiper cover 5.

[0044] In this embodiment, the groove 11 is preferably a through groove, and the sliding member 21 is an H-shaped wheel. In this embodiment, the shape of the adhesive strip mounting part is arc-shaped, so the shape of the through groove is also a corresponding arc shape. When the sliding member 21 moves in the groove 11, the sliding member 21 continuously changes position following the shape of the groove 11, so that the sliding member 21 drives the moving seat 23 and the rolling module 24 to move together, thereby realizing that the rolling module 24 maintains the distance between itself and the adhesive strip mounting part during the movement, and thus maintains a constant clamping force.

[0045] Preferably, the drive unit 3 includes a motor 31, a gear 32, and a rack 33; the motor 31 is connected to the support base 34; the gear 32 is connected to the power output end of the motor 31; the rack 33 is connected to the frame 1; the gear 32 meshes with the rack 33.

[0046] In this embodiment, by adopting the drive method of gear 32 and rack 33, the installation space required for drive unit 3 can be effectively reduced. Moreover, gear 32 and rack 33 have a long service life and low cost, making them suitable for mass production.

[0047] The support base 34 is slidably connected to the frame 1 via a slide rail. The motor 31 is connected to the support base 34. The motor 31 drives the gear 32 to roll on the rack 33, thereby moving the support base 34, which in turn moves the movable base 23 and the rolling module 24 forward.

[0048] Preferably, the movable seat 23 is provided with a sliding shaft 232; the support seat 34 is provided with a linear bearing 341; the sliding shaft 232 and the linear bearing 341 cooperate to realize the sliding connection between the movable seat 23 and the support seat 34.

[0049] In this embodiment, when the slider 21 moves within the groove 11, it causes the movable seat 23 to move closer to or further away from the rubber strip mounting portion of the wiper cover 5. The movable seat 23 and the support seat 34 are slidably connected by the sliding shaft 232 and the linear bearing 341. This not only improves the smoothness of the movable seat 23 moving toward the rubber strip mounting portion, but also allows the linear bearing 341 to withstand radial force, thus meeting the requirement of the support seat 34 driving the movable seat 23 to move forward.

[0050] Preferably, the fixing unit 4 includes a pressing module 41 and an overlapping boss 42; the overlapping boss 42 is adapted to the shape of the wiper cover 5; the pressing module 41 is used to press the wiper cover 5 onto the overlapping boss 42.

[0051] In this embodiment, multiple overlapping bosses 42 are arranged on the frame 1 according to the shape of the wiper cover 5, so that the wiper cover 5 can be placed stably on the overlapping bosses 42. After placement, the clamping module 41 is activated to clamp the wiper cover 5, so that the wiper cover 5 remains stationary when the rubber strip 2 is assembled, thus ensuring the assembly quality of the rubber strip 2.

[0052] Preferably, the clamping module 41 includes a cylinder 411 and a clamping member 412; the cylinder 411 is connected to the frame 1; and the clamping member 412 is connected to the power output end of the cylinder 411.

[0053] In this embodiment, after the wiper cover 5 is placed, the cylinder 411 is activated, causing the power output end of the cylinder 411 to move the clamping block toward the wiper cover 5 and press it against the wiper cover 5. After the rubber strip 2 is installed, the cylinder 411 is activated, and the power output end of the cylinder 411 causes the clamping block to disengage from the wiper cover 5.
