Description

Technical Field

[0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a sheet metal roll forming tool cleaning device and a cleaning method. Background Art

[0002] During the roll forming process of the inner and outer panels of the automobile body-in-white cover, firstly, glue is applied to the joint of the inner and outer panels, then the inner and outer panels are fitted together, and finally the inner and outer panels are roll formed using a sheet metal roll forming tool. In order to ensure the bonding strength of the inner and outer panels and the sealing performance of the joint, a small amount of glue will overflow from the edge of the inner and outer panels during the above process, so that residual glue will adhere to the rolling surface of the roller of the rolling tool. The existing technology cannot remove the residual glue on the roller in time, and the residual glue randomly adheres to the rolling surface of the roller. The uneven glue will cause surface quality defects of the workpiece when the roller is rolling with the residual glue, and the workpiece after roll forming will be dirty and difficult to clean.

[0003] In order to eliminate the quality defects caused by the above reasons and reduce the workload of subsequent cleaning of residual glue in the assembly, many car manufacturers generally adopt the method of applying a small amount of glue and applying glue away from the edge of the workpiece to prevent glue from overflowing at the joints of the sheet metal. This method results in poor waterproof performance and low strength of the assembly. Summary of the invention

[0004] In order to effectively solve the problems in the above-mentioned background technology, the present invention proposes a sheet metal roll forming tool cleaning device and a cleaning method.

[0005] The specific technical solutions are as follows:

[0006] A sheet metal roll forming tool cleaning device comprises a frame unit, a drive unit, a spray unit and a glue cleaning unit, wherein the frame unit is used to support the drive unit, the spray unit and the glue cleaning unit, the drive unit is used to drive a roller pressing wheel to rotate, the spray unit is used to spray a glue cleaning agent to the roller pressing wheel, and the glue cleaning unit is used to remove dirt on the roller pressing wheel.

[0007] Preferably, the rack unit comprises a rack, a support and a collection box, the rack is fixed on the ground, and the support and the collection box are respectively fixed on the top of the rack.

[0008] Preferably, there are two brackets, which are respectively located on both sides of the collecting box.

[0009] Preferably, the drive unit includes a first locking nut, a motor bracket, a reduction motor, a transmission shaft, a key, a second locking nut, a limit block, a hexagonal ball head drive shaft, a guide rail and a spring. The motor bracket is assembled to the upper part of the frame, and the reduction motor is installed on the motor bracket. The transmission shaft passes through the output shaft hole of the reduction motor and is fixed to the reduction motor through the key, the first locking nut and the second locking nut. The hexagonal ball head drive shaft is inserted into the transmission shaft and its rotation relative to the transmission shaft is limited by the guide rail so that the hexagonal ball head drive shaft can only move along the axial direction of the transmission shaft. A spring is assembled between the transmission shaft and the hexagonal ball head drive shaft, and a limit block is assembled on the outside of the hexagonal ball head drive shaft to limit the initial assembly position of the hexagonal ball head drive shaft.

[0010] Preferably, the spray unit comprises an atomizing nozzle, a universal bracket and a mounting plate, the mounting plate is mounted on the upper part of the reducer, and the atomizing nozzle is mounted on the mounting plate through the universal bracket.

[0011] Preferably, the glue cleaning unit comprises a quick-lock knob, a scraper, a fixed seat and a pneumatic slide, the pneumatic slide is mounted on a bracket, the fixed seat is assembled to the pneumatic slide, and the scraper is fixedly assembled to the fixed seat using a quick-lock knob.

[0012] Preferably, the glue cleaning units are in two sets, which are respectively fixed on the brackets.

[0013] The present invention also discloses a sheet metal roll forming tool cleaning method, comprising the cleaning device, and the method comprises the following steps:

[0014] 1. First, set the control air pressure of the pneumatic slide and adjust the spray state of the atomizing nozzle;

[0015] 2. The robot drives the roll forming tool B to the set position. At this time, the hexagonal ball head drive shaft is pressed into the transmission shaft by the rolling wheel by 4 to 5 mm;

[0016] 3. The spray nozzle sprays out atomized clear glue liquid, which wraps the outer surface of the residual glue on the roller wheel, effectively reducing the viscosity so that it will not stick to the scraper; at the same time, the reduction motor rotates to drive the hexagonal ball head drive shaft to rotate. When the outer hexagonal surface of the hexagonal ball head drive shaft coincides with the hexagonal hole on the roller wheel, the hexagonal ball head drive shaft extends under the action of the spring, and the hexagonal ball head drive shaft can drive the roller wheel to rotate;

[0017] 4. Control the pneumatic slide to extend, and the scraper is pressed onto the roller wheel as the pneumatic slide extends;

[0018] 5. The reduction motor continues to rotate, the atomizing nozzle continues to spray out the atomized adhesive remover, and the dirt on the roller is scraped off by the scraper;

[0019] 6. The pneumatic slide table is retracted, and the scraped dirt falls into the collection box;

[0020] 7. The atomizing nozzle stops spraying, the reduction motor stops rotating, and the robot drives the roller forming tool B to leave the glue cleaning machine A. At this point, the glue cleaning work is completed.

[0021] The beneficial effects of the present invention are as follows: the present invention first sprays a glue cleaning agent onto the rolling working surface and the end surface of the rolling wheel by a spray unit, rotates the rolling wheel by a driving unit of a glue cleaning machine, and then uses a controllable pressure glue cleaning unit to remove dirt on the rolling wheel. The residual glue liquid and attached dirt on the rolling wheel can be quickly removed, and the working surface and end surface of the rolling wheel are kept clean, thereby effectively eliminating the surface quality defects of the workpiece after roll forming caused by the residual glue liquid and attached dirt on the rolling wheel and the workload of subsequent transition glue cleaning of the workpiece assembly, thereby improving production efficiency and reducing production costs.

It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.

[0034] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0035] like Figure 2 As shown, a sheet metal roll forming tool cleaning device includes a frame unit 100, a drive unit 200, a spray unit 300 and a glue cleaning unit 400. First, the spray unit 300 sprays a glue cleaning agent onto a rolling working surface 502-1 and an end surface 502-2 of a rolling wheel 502, and the driving unit 200 of the glue cleaning machine is used to rotate the rolling wheel 502, and then the controllable pressure glue cleaning unit 400 is used to clean the dirt on the rolling wheel 502.

[0036] like Figure 3 As shown, the rack unit 100 is mainly composed of a rack 101, a bracket 102 and a collection box 103. The rack 101 is fixed on the ground, and the bracket 102 is fixedly assembled to the upper part of the rack 101 for positioning and assembling the adhesive cleaning unit 400. The collection box 103 is arranged under the scraper 402 in the adhesive cleaning unit 400 to collect the residual adhesive and other dirt scraped by the scraper 402.

[0037] like Figure 4and Figure 5 As shown, the drive unit 200 mainly includes a locking nut 201, a motor bracket 202, a reduction motor 203, a transmission shaft 204, a key 205, a locking nut 206, a stopper 207, a hexagonal ball head drive shaft 208, a guide rail 209, and a spring 210. The motor bracket 202 is assembled to the upper part of the frame 101, and the reduction motor is mounted on the motor bracket 202 behind the bracket 102. The transmission shaft 204 passes through the output shaft hole of the reduction motor 203 and is fixedly assembled to the reduction motor 203 through the key 205, the locking nuts 201 and 206. The hexagonal ball head drive shaft 208 is inserted into the transmission shaft 204, and the guide rail 209 is used to limit its rotation relative to the transmission shaft 204, so that the hexagonal ball head drive shaft 208 can only move along the axial direction of the transmission shaft 204. A spring 210 is installed between the transmission shaft 204 and the hexagonal ball head drive shaft 208, and a limit block 207 is installed outside the hexagonal ball head drive shaft 208 to limit the initial assembly position of the hexagonal ball head drive shaft 208. The hexagonal ball head structure of the hexagonal ball head drive shaft 208 can effectively eliminate the jamming fault caused by adjusting the relative position error between the roll forming tool B and the drive unit.

[0038] like Figure 6 As shown, the spray unit 300 is composed of an atomizing nozzle 301, a universal bracket 302 and a mounting plate 303. The mounting plate 303 is mounted on the reduction motor 203, and a set of atomizing nozzles 301 and universal brackets 302 are respectively provided on both sides of the mounting plate 303, and the nozzle position and atomization state can be adjusted.

[0039] like Figure 7 As shown, the glue cleaning unit 400 includes a quick-lock knob 401, a scraper 402, a fixed seat 403 and a pneumatic slide 404. The pneumatic slide 404 is installed on the bracket 102, and the fixed seat 403 is assembled on the pneumatic slide 404. The scraper 402 is fixedly assembled to the fixed seat 403 using the quick-lock knob 401. The air pressure of the air source connected to the pneumatic slide 404 is adjustable, which can ensure that the scraper 402 and the roller wheel 502 have a small contact pressure and can effectively remove dirt, thereby effectively extending the service life of the scraper 402.

[0040] like Figure 1 , Figure 8 and Fig. 9 The specific cleaning method is as follows:

[0041] 1. First, set the control air pressure of the pneumatic slide 404 and adjust the spray state of the atomizing nozzle 301.

[0042] 2. The robot drives the roll forming tool B to the set position. At this time, the hexagonal ball head drive shaft 208 is pressed into the transmission shaft 204 by the rolling wheel 502 by 4 to 5 mm.

[0043] 3. The spray nozzle 301 sprays atomized clear glue liquid, which wraps the outer surface of the residual glue on the roller 502, effectively reducing the viscosity so that it will not stick to the scraper 402. At the same time, the reduction motor 203 rotates to drive the hexagonal ball head drive shaft 208 to rotate. When the outer hexagonal surface of the hexagonal ball head drive shaft 208 coincides with the hexagonal hole on the roller 502, the hexagonal ball head drive shaft 208 extends under the action of the spring 210, and the hexagonal ball head drive shaft 208 can drive the roller 502 to rotate.

[0044] 4. The pneumatic slide 404 is controlled to extend, and the scraper 402 is pressed onto the roller wheel 502 as the pneumatic slide 404 extends.

[0045] 5. The reduction motor 203 continues to rotate, the atomizing nozzle 301 continues to spray out the atomized adhesive remover, and the dirt on the roller 502 is scraped off by the scraper 402.

[0046] 6. The pneumatic slide is retracted, and the scraped dirt falls into the collection box 103.

[0047] 7. The atomizing nozzle 301 stops spraying, the reduction motor 203 stops rotating, and the robot drives the roller forming tool B to leave the glue cleaning machine A. At this point, the glue cleaning work is completed.

[0048] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
