Description

Technical Field

[0001] This application relates to the field of brake friction pad assembly, and in particular to a brake friction pad assembly device. Background Technology

[0002] With the development of industrialization, industrial robots have been widely used. Industrial robots typically use transmission devices such as micro motors, servo motors, and stepper motors. In order to cooperate with the use of transmission devices, matching brakes are usually set up to achieve the function of braking and stopping.

[0003] Typically, a brake consists of components such as a housing, friction pads, a splined shaft, a splined sleeve, and an energizing component. The energizing component is installed inside the housing. A stepped groove is provided at the end of the housing. Glue is then injected into the stepped groove. After the glue is injected, the friction pads are installed in the stepped groove at the end of the housing. Then, the splined shaft is installed on the splined sleeve. Finally, the splined sleeve with the splined shaft is installed on the end of the housing where the friction pads are installed, thus completing the assembly of the brake.

[0004] Currently, the installation of friction pads on brakes is usually done manually. First, adhesive is applied to the housing, then the friction pads are placed inside, securing them in place with the adhesive. A pressure-holding device then maintains pressure on the friction pads within the housing. However, manually installing the friction pads is generally inefficient. Summary of the Invention

[0005] In order to improve the installation efficiency of friction pads, this application provides a brake friction pad assembly device.

[0006] This application provides a brake friction pad assembly device, which adopts the following technical solution:

[0007] A brake friction pad assembly device includes a housing, within which a conveying device is provided. The conveying device includes a turntable and a rotary drive, both of which are installed inside the housing. The rotary drive is connected to the turntable. The turntable has several workstations. Inside the housing, a gluing device, a feeding device, and a pressure holding device are sequentially arranged along the circumference of the turntable. The gluing device is used to apply glue to the brake housing. The feeding device is used to load the friction pads into the housing. The pressure holding device is used to press the friction pads and the housing together.

[0008] By adopting the above technical solution, the housing is placed on the station of the turntable. The turntable is driven to rotate by the rotary drive, so that the turntable drives the housing to the glue application device. The glue application device automatically applies glue to the housing. Then, the rotary drive continues to drive the turntable to rotate, so that the turntable drives the glued housing to the feeding device. The feeding device places the friction pad into the housing. Then, the turntable continues to rotate under the drive of the rotary drive to the pressure holding device for pressure holding, thereby realizing the installation of the friction pad. By mechanically and automatically installing the friction pad, the efficiency of friction pad installation is improved.

[0009] In one specific implementation, a positioning device is installed on the turntable at each workstation. The positioning device includes a positioning base and a cable fixing seat. The positioning base is provided with a fixing block and a positioning groove. A positioning post for positioning the brake housing is installed in the positioning groove. The cable fixing seat is located on one side of the positioning base and is provided with a positioning block. The positioning block is used to fix the cable on the brake housing between the positioning block and the cable fixing seat.

[0010] By adopting the above technical solution, the stability of the brake housing during transportation is improved by placing it in the positioning groove of the fixed block and positioning it with the positioning pin. Simultaneously, the positioning block and cable fixing seat position the cable on the housing, reducing the impact of the cable on the turntable's rotation.

[0011] In one specific implementation, a detection device is provided inside the chassis between the pressure holding device and the glue application device. The detection device includes a detection cylinder and a detection probe. The detection cylinder is mounted above the turntable, and the piston rod of the detection cylinder extends downward. The detection probe is mounted on the piston rod of the detection cylinder and is used to energize the cable located between the positioning block and the cable fixing seat.

[0012] By adopting the above technical solution, after the friction pads mounted on the housing are pressure-held, the turntable transports the housing containing the friction pads to the testing device. The testing cylinder drives the testing probe to descend, so that the testing probe can energize the cable extending from the housing, thereby realizing the detection of the resistance in the cable, so as to improve the yield of the brake.

[0013] In one specific implementation, a feeding device is also installed on the turntable at each station. The feeding device includes a knob, a control lever, a locking mechanism, and a pushing mechanism. The control lever is rotatably mounted inside the cable fixing seat, and one end of the control lever extends out of the side wall of the cable fixing seat. A reset component is installed on the control lever for controlling the control lever to reset. The knob is installed on the end of the control lever outside the cable fixing seat. The locking mechanism is installed on the cable fixing seat and is connected to the positioning block. The locking mechanism is also connected to the control lever. The pushing mechanism is installed on the positioning base and is connected to the control lever. The pushing mechanism is used to lift the brake housing from the positioning base.

[0014] By adopting the above technical solution, after being detected by the detection device, rotating the knob causes the control rod to rotate, which in turn drives the locking mechanism to rotate. This causes the locking mechanism to control the positioning block to rotate, thereby releasing the cable. At the same time, the control rod also controls the pushing mechanism to lift the housing from the positioning groove on the fixed block, thus facilitating material unloading.

[0015] In one specific implementation, the locking mechanism includes a locking spring and a locking rod. The locking rod is mounted on the positioning block, and the cable fixing seat has a locking hole for the locking rod to be inserted. The locking rod is connected to the control rod through the locking hole. The locking spring is mounted on the locking rod, with one end connected to the positioning block and the other end connected to the cable fixing seat.

[0016] By adopting the above technical solution, the control lever is separated from the unlocking lever by controlling its movement. This causes the positioning block to move upward under the action of the locking spring, thereby separating the positioning block from the cable fixing seat and making it easier to remove the cable from the cable fixing seat.

[0017] In one specific implementation, the control rod is provided with a bent portion, and the locking rod is provided with a snap-fit ​​wedge at the end away from the positioning block. The snap-fit ​​wedge engages with the bent portion of the control rod, and the bent portion is also connected to the pushing mechanism.

[0018] By adopting the above technical solution, when the locking rod is inserted into the locking hole, the locking wedge on the locking rod engages with the bent part of the control rod, thereby locking the locking rod to ensure that the positioning block fixes the cable to the cable fixing seat. At the same time, the control rod can also control the action of the pushing mechanism, thereby facilitating the unloading of the housing.

[0019] In one specific implementation scheme, the pushing mechanism includes a push plate, a first push rod, a second push rod, and a pushing spring. The fixed block has a mounting groove at one end near the positioning base. A top plate is installed in the mounting groove, and a push pin is installed on the top plate. The push pin passes through the top wall of the mounting groove and extends into the positioning groove. The first push rod is installed in the mounting groove, with one end connected to the bottom wall of the top plate and the other end slidably connected to the bottom wall of the mounting groove. The second push rod is also installed in the mounting groove, with one end connected to the bottom wall of the top plate and the other end also connected to the bottom wall of the mounting groove. The first and second push rods are rotatably connected and are arranged in a cross configuration. A connecting rod is rotatably mounted on the end of the push rod away from the top plate. One end of the connecting rod extends towards the control rod, and the end of the second push rod away from the top plate is slidably connected to the connecting rod. The push spring is mounted on the connecting rod, and one end of the push spring abuts against the side wall of the first push rod, while the other end abuts against the side wall of the second push rod. The push plate is slidably mounted on the positioning base, and one end of the push plate extends into the mounting groove and abuts against the end of the second push rod away from the top plate, while the other end extends to the control rod. A connecting groove is provided at the end of the push plate near the mounting groove, and the end of the connecting rod away from the first push rod is slidably disposed in the connecting groove. A pushing inclined surface is provided at the end of the push plate near the control rod, and the pushing inclined surface is used to abut against the bent part of the control plate.

[0020] By adopting the above technical solution, when the housing needs to be unloaded, the control rod is rotated, causing the bent part of the control rod to move the push plate away from the cable fixing seat. This causes the push plate to move the second push rod, which compresses the push spring and slides along the connecting rod towards the first push rod. This causes the first and second push rods to lift the top plate, which in turn causes the top plate to lift the ejector pin, thus facilitating the unloading of the brake housing.

[0021] In one specific implementation, the feeding device includes a conveying mechanism, which includes a vibratory feeder and a conveying rail. The vibratory feeder is mounted on one side of the machine housing, and the conveying rail is mounted on the machine housing. One end of the conveying rail is connected to the output end of the vibratory feeder, and the other end extends toward the turntable.

[0022] By adopting the above technical solution, the friction pads are transported to the conveyor rail by the vibratory feeder, so that the friction pads are transported along the conveyor rail to the turntable, which facilitates the assembly of the friction pads and the brake housing.

[0023] In one specific implementation, the feeding device further includes a transfer mechanism, which includes a transfer platform, a transfer cylinder, a transfer assembly, and an adsorption column. The transfer cylinder is installed inside the housing and located below the conveyor rail, with the axis of the piston rod of the transfer cylinder perpendicular to the axis of the conveyor rail. The transfer platform is installed on the piston rod of the transfer cylinder and has a receiving groove for receiving materials on the conveyor rail. The adsorption column is installed inside the housing and located above the transfer platform. The transfer assembly is installed inside the housing and connected to the adsorption column, which is used to adsorb materials on the transfer platform.

[0024] By adopting the above technical solution, when the friction plate is conveyed to the receiving groove on the transfer platform, the transfer platform is moved by the transfer cylinder, so that the receiving groove is misaligned with the conveying rail. The transfer component controls the adsorption column to move to the receiving groove, and then the adsorption column picks up the friction plate from the transfer platform. The transfer component then controls the adsorption column to move to the turntable and place the friction plate in the housing of the brake, thus facilitating the automatic installation of the friction plate.

[0025] In one specific implementation, the transfer mechanism further includes a centering assembly, which includes a centering cylinder and a centering rod. The centering cylinder is installed inside the housing and is located above the adsorption column, with the piston rod of the centering cylinder facing the adsorption column. The centering rod is slidably installed inside the adsorption column along the axial direction of the adsorption column, with both ends of the centering rod extending outward from the end of the adsorption column. The end of the centering rod near the centering cylinder is connected to the piston rod of the centering cylinder.

[0026] By adopting the above technical solution, when the friction plate is picked up from the transfer table, the centering rod is first moved downward by the centering cylinder so that the centering rod is inserted into the hole on the friction plate, thereby positioning the friction plate first. Then, the friction plate is adsorbed by the adsorption column, which reduces the misalignment of the friction plate during the adsorption process, thus preventing the problem of inaccurate positioning of the friction plate when it is installed in the brake housing.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. This application, by setting up an adhesive application device, a feeding device, and a pressure holding device, facilitates the automatic assembly of friction plates through mechanical devices, thereby improving the assembly efficiency of friction plates.

[0029] 2. This application provides a feeding device to facilitate the feeding of the tested brake housing.

[0030] 3. This application provides a centering component to facilitate the positioning of the friction pad, thereby reducing the displacement of the friction pad during the adsorption process. Attached Figure Description

Detailed Implementation

[0041] The present application will be further described in detail below with reference to the accompanying drawings.

[0042] This application discloses a brake friction pad assembly device, referring to... Figure 1 It includes a chassis 1, a conveying device 2 installed inside the chassis 1, and an adhesive applicator 3, a feeding device 4 and a pressure holding device 5 installed in sequence along the circumference of the conveying device 2 inside the chassis 1.

[0043] Reference Figure 1 The brake housing is placed in the conveying device 2, which then transports it to the gluing device 3. Glue is applied to the inner wall of the brake housing by the gluing device 3. The conveying device 2 then transports the glued brake housing to the loading device 4, which feeds the friction pads into the brake housing. The conveying device 2 then transports the brake housing with the friction pads to the pressure holding device 5 for pressing and pressure holding, thereby completing the assembly of the friction pads and the brake housing and maintaining a certain pressure between them.

[0044] Reference Figure 1The conveying device 2 includes a turntable 21 and a rotary drive 22. The turntable 21 is rotatably mounted inside the housing 1, and the rotary drive 22 is mounted inside the housing 1 and connected to the turntable 21. The rotary drive 22 is prior art in this field and will not be described in detail here. The turntable 21 is provided with several workstations. In this embodiment, four workstations are provided and are evenly arranged along the circumference of the turntable 21.

[0045] Reference Figure 2 and Figure 3 Each workstation is equipped with a positioning device 6, which includes a positioning base 61 and a cable fixing seat 62. The positioning base 61 is fixedly installed on the top wall of the turntable 21. A fixing block 611 is fixedly installed on the top wall of the positioning base 61. A positioning groove 612 for placing the brake housing is opened on the top wall of the fixing block 611. A positioning post 613 for insertion into the brake housing is fixedly installed on the bottom wall of the positioning groove 612. The cable fixing seat 62 is fixedly installed on the turntable 21 on the side of the positioning base 61 away from the edge of the turntable 21. A cable fixing groove 621 is opened on the top wall of the cable fixing seat 62. A positioning block 63 is detachably installed on the top wall of the cable fixing seat 62. A conductive copper block 631 is fixedly installed on the bottom wall of the positioning block 63 and is inserted into the cable fixing groove 621.

[0046] Reference Figure 3 and Figure 4 Each working position on the turntable 21 is equipped with a feeding device 7, which includes a knob 71, a control lever 72, a locking mechanism 74, and a pushing mechanism 75. The control lever 72 is rotatably mounted inside the cable fixing seat 62, with one end of the control lever 72 extending out of the side wall of the cable fixing seat 62. The knob 71 is fixedly mounted on the end of the control lever 72 outside the cable fixing seat 62. A reset component is also mounted on the control lever 72, which includes a torsion spring 73. One end of the torsion spring 73 is fixedly connected to the side wall of the cable fixing seat 62, and the other end is fixedly connected to the side wall of the knob 71 near the control lever 72. The portion of the control lever 72 located inside the cable fixing seat 62 has an upwardly bent portion 721. The cable fixing seat 62 has a rotating groove for the bent portion 721 to rotate. The bent portion 721 of the control lever 72 is connected to the locking mechanism 74 and the pushing mechanism 75.

[0047] Reference Figure 4 and Figure 5The locking mechanism 74 includes a locking spring 743 and a locking rod 741. The locking rod 741 is fixedly installed on the bottom wall of the positioning block 63. A locking hole 623 for the locking rod 741 to be inserted is provided on the top wall of the cable fixing seat 62. A snap-fit ​​wedge 742 is fixedly installed on the end of the locking rod 741 away from the positioning block 63. The snap-fit ​​wedge 742 snaps into the bent part 721 of the control rod 72, and the cross-section of the snap-fit ​​wedge 742 is trapezoidal, with the hypotenuse of the trapezoid abutting against the bent part 721 of the control rod 72. The locking spring 743 is installed on the locking rod 741. A buffer plate 744 is also slidably installed on the side wall of the locking rod 741. One end of the locking spring 743 abuts against the top wall of the buffer plate 744, and the other end abuts against the bottom wall of the positioning block 63.

[0048] Reference Figure 4 and Figure 5 When positioning block 63 needs to be positioned, the locking rod 741 of positioning block 63 is inserted into locking hole 623, which compresses locking spring 743 and causes the inclined side of locking wedge 742 to abut against bending portion 721 of control rod 72. As locking rod 741 moves downward, bending portion 721 of control rod 72 slides along inclined side of locking wedge 742, causing control rod 72 to rotate, thereby compressing torsion spring 73. When bending portion 721 of control rod 72 passes the end of locking wedge 742, control rod 72 rotates back to its original position under the action of torsion spring 73, thereby locking wedge 742 and bending portion 721 of control rod 72, thus locking positioning block 63.

[0049] Reference Figure 4 and Figure 5The pushing mechanism 75 includes a push plate 751, a first push rod 754, a second push rod 755, and a pushing spring 756. A mounting groove 615 is provided at one end of the fixing block 611 near the positioning base 61. A top plate 758 is slidably mounted vertically within the mounting groove 615. Several push pins 759 are fixedly mounted on the top plate 758. These push pins 759 pass through the inner top wall of the mounting groove 615 and extend into the positioning groove 612, with the push pins 759 slidably connected to the inner top wall of the mounting groove 615 on the fixing block 611. A pushing groove 614 is provided within the positioning base 61, communicating with the mounting groove 615. The first push rod 754 is installed within the mounting groove 615, with one end slidably connected to the bottom wall of the top plate 758, and the other end extending into the pushing groove 614 and hinged to the bottom wall of the pushing groove 614. The second push rod 755 is installed in the mounting groove 615 in a cross configuration with the first push rod 754. The second push rod 755 and the first push rod 754 are hinged at the intersection. One end of the second push rod 755 is slidably connected to the bottom wall of the top plate 758, and the other end of the second push rod 755 is slidably connected to the bottom wall of the push groove 614. A connecting rod 757 is installed at one end of the first push rod 754 located in the push groove 614. One end of the connecting rod 757 is hinged to the first push rod 754, and the other end extends away from the first push rod 754. The connecting rod 757 is slidably connected to the end of the second push rod 755 located in the push groove 614. A push spring 756 is installed on the connecting rod 757. One end of the push spring 756 abuts against the first push rod 754, and the other end abuts against the second push rod 755.

[0050] Reference Figure 4 and Figure 5 A control groove 622 is provided on the side wall of the cable fixing base 62 near the positioning base 61. The control groove 622 communicates with the push groove 614. One end of the push plate 751 is slidably installed in the push groove 614, and the other end extends into the control groove 622. The end of the push plate 751 located in the control groove 622 is provided with a pushing slope, which is used to abut against the bent part 721 of the control rod 72. A connecting groove 752 is provided at the end of the push plate 751 located in the push groove 614. The end of the connecting rod 757 away from the first push rod 754 is slidably installed in the connecting groove 752, and the end of the push plate 751 located in the push groove 614 abuts against the end of the second push rod 755 located in the push groove 614.

[0051] Reference Figure 5 and Figure 6When the controller housing needs to be unloaded, the control lever 72 is rotated so that the bent part 721 of the control lever 72 abuts against the pushing slope of the push plate 751, thereby pushing the push plate 751 to move away from the cable fixing seat 62. This causes the push plate 751 to push one end of the second push rod 755 located in the push groove 614, thereby causing the end of the second push rod 755 located in the push groove 614 to move towards the first push rod 754. This reduces the distance between the first push rod 754 and the second push rod 755 and compresses the push spring 756, thereby lifting the top plate 758 upward. This causes the top plate 758 to drive the ejector pin 759 to lift the controller housing from the positioning groove 612, so as to facilitate the unloading of the controller housing.

[0052] Reference Figure 1 The glue application device 3 includes a glue application head 31 and a glue application drive 32. The glue application drive 32 is installed inside the chassis 1 near the turntable 21. The glue application head 31 is installed on the glue application drive 32.

The vibratory plate 411 is fixedly installed on one side of the housing 1, and the conveying rail 412 is fixedly installed on the housing 1. One end of the conveying rail 412 is connected to the output end of the vibratory plate 411, and the other end extends toward the turntable 21.

[0054] Reference Figure 7 and Figure 8 The feeding device 4 also includes a transfer mechanism 42, which includes a transfer platform 421, a transfer cylinder 425, a transfer assembly 426, and an adsorption column 423. The transfer cylinder 425 is fixedly installed inside the housing 1 and located below the turntable 21. The piston rod of the transfer cylinder 425 extends away from the turntable 21 along the radius of the turntable 21, and the axis of the piston rod of the transfer cylinder 425 is perpendicular to the axis of the conveying rail 412. The transfer platform 421 is fixedly installed on the piston rod of the transfer cylinder 425. A receiving groove 422 is provided on the side wall of the transfer platform 421 near the conveying rail 412. The receiving groove 422 is used to support the friction plates conveyed on the conveying rail 412.

[0055] Reference Figure 7 and Figure 8The transfer assembly 426 includes a transfer frame 4261, a transverse cylinder 4262, and a lifting cylinder 4264. The transfer frame 4261 is fixedly installed inside the housing 1, and the transfer frame 4261 is located on the side of the transfer cylinder 425 away from the conveyor rail 412. A slide plate 4263 is slidably installed on the upper end of the transfer frame 4261 in the horizontal direction. The transverse cylinder 4262 is fixedly installed on the upper end of the transfer frame 4261, and the axis of the piston rod of the transverse cylinder 4262 is parallel to the axis of the piston rod of the transfer cylinder 425. The piston rod of the transverse cylinder 4262 is fixedly connected to the side wall of the slide plate 4263. The lifting cylinder 4264 is fixedly installed on the side wall of the slide plate 4263, and the piston rod of the lifting cylinder 4264 extends downward. The lifting frame 4265 is fixedly installed on the piston rod of the lifting cylinder 4264. The adsorption column 423 is fixedly installed on the side wall of the lifting frame 4265, and the lower end of the adsorption column 423 is provided with an adsorption port. The adsorption port of the adsorption column 423 is connected to an external air source, and the adsorption column 423 adsorbs the friction plate in the receiving groove 422 through the adsorption port.

[0056] Reference Figure 7 and Figure 8 The transfer mechanism 42 also includes a centering assembly 427, which includes a centering cylinder 4272 and a centering rod 4271. A centering hole 424 is provided at the axis of the adsorption column 423. The centering rod 4271 is slidably installed in the centering hole 424 in the vertical direction, with the upper end of the centering rod 4271 extending upward out of the adsorption column 423 and the lower end of the centering rod 4271 extending downward out of the adsorption column 423. The lower end of the centering rod 4271 is used to insert into the shaft hole at the axis of the friction plate. The centering cylinder 4272 is fixedly installed on the side wall of the lifting frame 4265, and the piston rod of the centering cylinder 4272 extends downward and is fixedly connected to the upper end of the centering rod 4271.

[0057] Reference Figure 7 and Figure 8The vibratory feeder 411 transports the friction plates to the transfer table 421 via the conveyor rail 412. Once a friction plate is transported into the receiving groove 422, the transfer cylinder 425 controls the transfer table 421 to move away from the turntable 21, causing the side wall of the transfer table 421 to block the end of the conveyor rail 412 near the transfer table 421, thus stopping the transport of the friction plate. Simultaneously, the transverse cylinder 4262 controls the slide plate 4263 to move above the transfer table 421, causing the slide plate 4263 to move the lifting cylinder 4264 above the transfer table 421. Then, the lifting cylinder 4264 controls the lifting frame 4265 to descend, causing the suction column 423 and the centering rod 4271 on the lifting frame 4265 to descend. Finally, the centering cylinder 4272 controls the centering rod 4271 to descend. The friction plate is moved and inserted into the shaft hole of the friction plate to reduce the movement of the friction plate during adsorption. Then, the external air source controls the adsorption column 423 to pick up the friction plate from the receiving groove 422. Then, the lifting cylinder 4264 controls the lifting frame 4265 to rise, and the lateral cylinder 4262 controls the slide plate 4263 to move towards the turntable 21, so that the adsorption column 423 drives the friction plate to the work position above the turntable 21. Then, the lifting cylinder 4264 controls the lifting frame 4265 to fall, so that the adsorption column 423 sends the friction plate into the housing of the brake. Finally, the adsorption column 423 releases the friction plate, the lateral cylinder 4262 controls the slide plate 4263 to reset, the lifting cylinder 4264 controls the lifting frame 4265 to reset, and the centering cylinder 4272 controls the centering rod 4271 to reset.

[0058] Reference Figure 1 The pressure holding device 5 includes a pressure holding cylinder 51, a pressure holding block 52, and a pressure holding frame. The pressure holding frame is fixedly installed inside the housing 1. The pressure holding cylinder 51 is fixedly installed on the pressure holding frame and is located above the turntable 21. The piston rod of the pressure holding cylinder 51 extends downward. The pressure holding block 52 is fixedly installed on the piston rod of the pressure holding cylinder 51. The pressure holding block 52 is used to press the friction plate against the housing.

[0059] Reference Figure 1 and Figure 2 Inside the housing 1, between the pressure holding device 5 and the glue application device 3, a detection device 8 is also installed. The monitoring device includes a detection cylinder 81 and a detection probe 83. The detection cylinder 81 is fixedly installed inside the housing 1 and is located above the turntable 21. The piston rod of the detection cylinder 81 extends downward. A detection block 82 is fixedly installed on the piston rod of the detection cylinder 81. The detection probe 83 is fixedly installed on the detection block 82 and is used to contact the conductive copper block 631 on the positioning block 63.

[0060] The working principle of this embodiment is as follows: the brake housing is mounted on the positioning base 61 at the work station of the detection device 8, so that the brake housing is positioned by the positioning pin 613 and the positioning groove 612, and the cable extending from the brake housing is placed in the cable fixing groove 621. Then, the positioning block 63 is mounted on the cable fixing seat 62, so that the conductive copper block 631 on the positioning block 63 presses the cable, and the locking rod 741 on the positioning block 63 is inserted into the locking hole 623, thereby compressing the locking spring 743. After the locking rod 741 is inserted into the locking hole 623, the inclined edge of the locking wedge 742 on the locking rod 741 abuts against the bent portion 721 of the control rod 72, thereby pushing the control rod 72 to rotate through the bent portion 721. When the bent portion 721 of the control rod 72 passes the end point of the locking wedge 742 away from the locking rod 741, the control rod 72 rotates upward and resets under the action of the torsion spring 73, so that the bent portion 721 of the control rod 72 rotates to the top of the locking wedge 742 and abuts against the top wall of the locking wedge 742, thereby engaging with the locking wedge 742 and thus positioning the positioning block 63.

[0061] Next, the rotary drive 22 controls the turntable 21 to rotate, thereby causing the brake housing to rotate to the glue application device 3, where glue is applied into the brake housing. Then, the rotary drive 22 drives the turntable 21 to continue rotating, thereby moving the brake housing to the feeding device 4, where the friction pads are fed into the brake housing. Then, the rotary drive 22 continues to drive the turntable 21 to rotate, causing the turntable 21 to move the brake housing to the pressure holding device 5, where the pressure holding cylinder 51 controls the pressure holding block 52 to descend, thereby pressing the friction pads and the brake housing together.

[0062] Finally, the rotary drive 22 drives the turntable 21 to rotate, rotating the brake housing back to the detection device 8. The detection cylinder 81 controls the detection block 82 to descend, thereby driving the detection probe 83 to descend and contact the conductive copper block 631. By energizing the detection probe 83, the resistance and load performance of the cable on the brake housing are tested.

[0063] After the cable inspection is completed, the knob 71 is rotated in the direction of the positioning base 61, which causes the control lever 72 to rotate. This causes the bent part 721 of the control lever 72 to separate from the locking wedge block 742, and the locking lever 741 to move upward under the action of the locking spring 743. This causes the positioning block 63 to separate the conductive copper block 631 from the cable, thereby releasing the cable from its fixation. When the bent portion 721 of the control lever 72 separates from the snap-fit ​​wedge 742, the bent portion 721 of the control lever 72 abuts against the pushing slope of the push plate 751, and pushes the push plate 751 away from the cable fixing seat 62, thereby causing the push plate 751 to push the second push rod 755, thereby shortening the distance between the second push rod 755 and the first push rod 754 and compressing the push spring 756, thereby causing the first push rod 754 and the second push rod 755 to drive the top plate 758 to move upward, so that the ejector pin 759 on the top plate 758 pushes the brake housing off the fixing block 611 to facilitate unloading.

[0064] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
