[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 and Figure 5 The utility model provides an embodiment: a steel back glue coating device for producing oil drilling rig brake pads, comprising a shell 1, a mounting sleeve 2 is fixedly connected to the bottom side of the shell 1, a mounting member 4 is arranged inside the mounting sleeve 2, a glue coating head 3 is fixedly connected to the bottom side of the mounting member 4, a positioning wheel frame 10 is arranged on the left side of the glue coating head 3, one end of the positioning wheel frame 10 is fixedly connected to the outer wall of the shell 1, a cleaning sleeve 12 is arranged on the outer wall of a roller 11 rotatably connected to the other end of the positioning wheel frame 10, and one end of the cleaning sleeve 12 is connected to the other end. The housing 1 is connected by Velcro; a sliding sleeve 15 is fixedly connected to the right side of the housing 1, a sliding rail 16 is slidably connected inside the sliding sleeve 15, an external mounting member 17 is fixedly connected to the top side of the sliding rail 16, the bottom end of the telescopic rod 13 located on the top side of the housing 1 is fixedly connected to the top side of the housing 1, the top end of the telescopic rod 13 is fixedly connected to the bottom side of the external mounting member 17, and a spring 14 is sleeved on the outer wall of the telescopic rod 13, one end of the spring 14 is connected to the top side of the housing 1, and the other end of the spring 14 is connected to the bottom side of the external mounting member 17;

[0027] Specifically, the glue coating device is located above the top side of the oil rig brake pad, and the external mounting member 17 is connected to an external xyz platform for controlling movement, which is used to move the glue coating device. The oil rig brake pad is fixed by an external fixing mechanism to prevent shaking, and the arc-shaped steel back faces upward. The roller 11 is located at the front side of the glue coating head 3 in the direction of glue coating, and its height is slightly lower than the output end of the glue coating head 3. A feed port is provided on the outer wall of the glue coating head 3, which is used to receive the glue for glue coating transported by the external pipe, and the glue drips on the output end of the bottom side toward the steel back of the brake pad. The sliding sleeve 15 slides on the slide rail 16, which can ensure the stability of the part including the shell 1 and connected to the shell 1 when it is displaced. By arranging a telescopic rod 13 in the spring 2 14, it helps to prevent the spring 2 14 from being offset and bent when the two ends of the spring 2 14 are compressed, thereby improving the stability of the spring 2 14. When applying glue, the xyz platform will move the device to the top of the oil rig brake pad, and move the device downward until the positioning wheel frame 10 and the roller 11 abut against the end of the brake pad steel back. At this time, since the positioning wheel frame 10 and the roller 11 abut against the arc portion of the steel back, the housing 1 connected to the positioning wheel frame 10 and the structure including the glue head 3 connected to the housing 1 are moved upward, the sliding sleeve 15 slides on the sliding rail 16, the telescopic rod 13 shortens and compresses the spring 2 14, and then the glue is applied forward along the steel back. The roller 11 rolls and displaces along the arc track on the arc part, and continues to abut. When gradually moving toward the trough, the spring 2 14 will reset to a certain extent, pushing the structure including the glue coating head 3 on the bottom side to move downward. When rising along the arc, the structure including the glue coating head 3 rises, and the spring 2 14 will be recompressed until the glue coating is completed. The glue coating head 3 is displaced under the guidance of the rolling abutment of the roller 11 on the arc part, and the positioning glue coating is performed, thereby greatly improving the accuracy of glue coating and improving the production quality of the brake pad. The cleaning sleeve 12 with both ends fitted on the roller 11 by Velcro will clean the part of the brake pad that needs to be glued when the roller 11 rolls on the arc part of the brake pad to prevent stains on the surface of the brake pad from affecting the glue coating, further improving the quality of glue coating.

[0028] Reference Figure 2 , Figure 3 and Figure 4, the two through slots respectively provided on the left and right sides of the mounting sleeve 2 are slidably connected with abutment members 5, the outer wall of the abutment member 5 is fixedly connected with a limiting member 6, a limiting slide slot is provided inside the through slot, and the limiting member 6 is slidably connected in the limiting slide slot; a spring 7 is provided inside the spring slot provided inside the mounting member 4, and clamps 8 are provided at both ends of the spring 7, the clamps 8 are located in the through slot and abut against one side of the abutment member 5; a plug-in 9 is fixedly connected to the top side of the mounting member 4, a slot is provided on the top side of the mounting sleeve 2, the plug-in 9 is plugged into the inside of the slot, the plug-in 9 is made of a magnet, the mounting sleeve 2 is made of metal iron, and the mounting sleeve 2 and the slot are magnetically attracted to each other;

[0029] Specifically, by sliding the limit member 6 in the limit slide groove, the limit member 6 can be prevented from falling out of the through groove. The maximum diameter of the clamp 8 is larger than the opening of the spring groove, thereby preventing the clamp 8 from falling out of the spring groove. When it is necessary to replace the glue coating head 3 of different specifications or replace a new glue coating head 3 according to needs, by pressing the limit member 6 protruding from the outside, the limit members 6 at both ends will apply force to the clamp 8 abutting against its outer wall, thereby displacing the clamp 8 and disengaging it from the through groove, thereby releasing the clamping connection with the hole through groove, and then pulling the mounting member 4 to pull out the plug-in 9 magnetically attracted in the slot, and removing the mounting member 4 together with the glue coating head 3 from the mounting sleeve 2, and then installing the replaced glue coating head 3 connected to the mounting member 4, and aligning the mounting member 4 with the mounting sleeve 2. When the inclined surface structure at the opening of the mounting sleeve 2 contacts with the clamping piece 8, the clamping piece 8 will be squeezed along the inclined surface and then displaced, squeezing the internal spring 7 until it is completely contracted into the spring groove, and the mounting piece 4 continues to penetrate into the interior of the mounting sleeve 2 until the plug-in 9 is magnetically inserted into the slot. At this time, the clamping piece 8 comes to the position of the through groove and is no longer squeezed by the inner wall of the mounting sleeve 2. The spring 7 now drives the clamping piece 8 to reset, and the clamping piece 8 is snapped into the through groove, thereby completing the fixation and completing the replacement of the glue coating head 3.

[0030] Working principle: When applying glue, the xyz platform will move the device to the top of the oil rig brake pad, and move the device downward until the positioning wheel frame 10 with the roller 11 abuts against the end of the brake pad steel back. At this time, since the positioning wheel frame 10 with the roller 11 abuts against the arc part of the steel back, the housing 1 connected to the positioning wheel frame 10 and the structure including the glue head 3 connected to the housing 1 are moved upward, the sliding sleeve 15 slides on the sliding rail 16, and the telescopic rod 13 shortens and compresses the spring. The second spring 14 then moves forward along the steel back to apply glue, and the roller 11 rolls and displaces along the arc trajectory on the arc part and continues to abut. When gradually moving toward the trough, the spring 14 will reset to a certain extent, pushing the structure including the glue coating head 3 on the bottom side to move downward. When rising along the arc, the structure including the glue coating head 3 rises, which will re-compress the spring 14 until the gluing is completed. During the whole process, the glue coating head 3 is displaced under the guidance of the rolling abutment of the roller 11 on the arc part to carry out positioning and gluing. When it is necessary to replace the glue coating head 3 of different specifications or replace a new glue coating head 3 according to the needs, by pressing the protruding limit pieces 6 on the outside, the limit pieces 6 at both ends will apply force to the clamping pieces 8 abutting against the outer wall thereof, thereby displacing the clamping pieces 8 to disengage them from the through slots, thereby releasing the clamping connection with the hole through slots, and then pulling the mounting piece 4 to pull out the plug-in 9 magnetically attracted in the slot, and removing the mounting piece 4 together with the glue coating head 3 from the mounting sleeve 2, and then connecting the replaced glue coating head 3 to the mounting piece 4 for installation, and aligning the mounting piece 4 with the mounting sleeve 2. When the inclined surface structure at the opening of the mounting sleeve 2 contacts with the clamping piece 8, the clamping piece 8 will be squeezed along the inclined surface and then displaced, squeezing the internal spring 7 until it is completely contracted into the spring groove, and the mounting piece 4 continues to penetrate into the interior of the mounting sleeve 2 until the plug-in 9 is magnetically inserted into the slot. At this time, the clamping piece 8 comes to the position of the through groove and is no longer squeezed by the inner wall of the mounting sleeve 2. The spring 7 now drives the clamping piece 8 to reset, and the clamping piece 8 is snapped into the through groove, thereby completing the fixation and completing the replacement of the glue coating head 3.
