In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components thereof have been omitted.

As shown in fig. 1 to 37, an embodiment of the present invention discloses a brake pad assembling apparatus by which a collar 400 can be automatically assembled to a brake pad 500, and the transportation of the brake pad 500 is completed by the assembling apparatus.

Before describing the assembly apparatus of the present invention, a simple description will be given of the structure and assembly requirements of the brake pad 500 and the collar 400 to be assembled.

As shown in fig. 1 and 2, the collar 400 has a generally circular outer edge, the collar 400 having opposing warped sides 401 and flattened sides 402, the warped sides 401 being higher than the flattened sides 402, and the warped sides 401 transitioning with the flattened sides 402 through the chamfer 1211; extending radially inwardly from the warp side 401 are two extensions 403, between which extensions 403 are formed grooves allowing radial passage of the parts of the strip-like structure, which grooves are not limited to what can be used as guide grooves 404, which extensions 403 are bent in an arc shape in the middle to enclose a ring 405.

As shown in fig. 3 to 5, the brake pad 500 has columns 501 arranged in a substantially matrix, and the columns 501 have mounting grooves 5011, and the mounting process requires that each column 501 is sleeved with the collar 400 and the collar 400 is clamped in the mounting grooves 5011.

Based on the above-described structure and installation requirements of the collar 400 and the brake pad 500, if an automated assembly method is adopted, it will be appreciated that the assembly apparatus of the present invention needs to have the following functions:

1. a function of continuously carrying the collar 400 to a specified position.

2. The collar 400 transported to a specified position is incorporated into the function of the brake pad 500.

3. So that each cylinder 501 on the brake pad 500 can be fitted into the collar 400 and the assembled brake pad 500 can be removed and the function of an unassembled brake pad 500 can be provided.

Based on the above functional requirements, as shown in fig. 6, the assembly device provided by the present invention includes: conveying mechanism 100, tooling mechanism 200 and moving mechanism 300. Wherein: the delivery mechanism 100 is used to continuously transport the collar 400 to a designated location; the tool mechanism 200 is used for loading the clamping ring 400 conveyed to a specified position into the brake pad 500; the movement mechanism 300 is used to enable each cylinder 501 on the brake pad 500 to be loaded into the collar 400 and to enable the assembled brake pad 500 to be removed and to provide the function of an unassembled brake pad 500.

In the present invention, the above-mentioned moving mechanism 300 is used for adjusting the horizontal position of the brake pad 500 so that each upper column 501 of the brake pad 500 is installed into the collar 400 by the fixture mechanism 200, and is used for continuously transporting the brake pad 500 and transporting the brake pad 500, thereby realizing assembly flow of the brake pad 500.

The conveying mechanism 100, the tooling mechanism 200, and the moving mechanism 300 in the assembly apparatus are described in detail below.

Conveying mechanism 100

As shown in fig. 7 to 19, the conveying mechanism 100 includes: the feeder 110, the guide 120, the guide mechanism 130, the correction mechanism 140, and the driving mechanism.

As shown in fig. 7 and 8, the feeding machine 110 is a vibration sorting feeding machine 110 in the prior art, the middle part of the feeding machine 110 is provided with a cylindrical accommodating part 111 and a spiral groove 112 surrounding the accommodating part 111, a large number of clips 400 are accommodated on the accommodating part 111, and the feeding machine 110 can sequentially enter the spiral groove 112 and move towards the port of the spiral groove 112 by vibration of the clamping ring 400. The selected prior art feeder 110 has only a function of arranging and moving the collars 400 in sequence, but is not capable of moving the collars 400 in a constant posture, for example, the collars 400 located on the spiral grooves 112 are not oriented with the guide grooves 404 or the warp sides 401 thereof being indefinite.

As shown in fig. 8 to 10, the guide 120 is substantially bar-shaped, a first end of the guide 120 is abutted with an end of the spiral groove 112, and a second end of the guide 120 extends toward the guide 130 and is abutted with the guide 130. The guide part 120 is provided with a sinking groove 121, the sinking groove 121 extends along the extending direction of the guide part 120 and penetrates through two ends of the guide part 120, a first guide groove 122 and a second guide groove 123 are respectively formed on two groove walls of the sinking groove 121, the first guide groove 122 is higher than the second guide groove 123, the groove bottom of the sinking groove 121 forms an inclined surface 1211 matched with the bottom of the clamping groove, and thus, when the clamping ring 400 moving towards the guide part 120 is adjusted to an attitude that the warping side 401 corresponds to the first guide groove 122 or the flattening side 402 corresponds to the second guide groove 123, the clamping ring 400 can slide into the guide part 120.

From the above, the following actions occur in the collar 400 at the notch of the spiral groove 112: if the warp side 401 of the collar 400 corresponds to the first guide groove 122, the collar 400 smoothly enters the sink groove 121 and is ejected from the second end of the guide portion 120 along the sink groove 121; if the warp side 401 of the clip 400 does not correspond to the first guide groove 122, the first end of the guided portion 120 is stopped, and at this time, the clip 400 is frequently adjusted in posture by vibration, and finally adjusted to a posture in which the warp side 401 corresponds to the first guide groove 122, and further slid into the sinking groove 121 of the guide portion 120, and finally ejected from the second end of the guide portion 120.

The guide 120 described above has advantages in that: the guide 120 can adjust the attitude of the collars 400 such that each collar 400 can be ejected from the second end of the guide 120 in substantially the same and determined attitude.

As shown in fig. 10 to 19, the guide mechanism 130 includes: a guide platform 131 and a guide 132. The second end of the guide 120 extends to the first end of the guide land 131 so that the collar 400 ejected from the guide 120 falls into the first end of the guide land 131; and the guide 120 intersects the guide platform 131 substantially perpendicularly; the guiding platform 131 is substantially strip-shaped, so that the second end of the guiding platform 131 extends to a designated position, so as to facilitate the transportation of the collar 400 to the designated position; the guide portion 132 is substantially in a bar shape, the guide portion 132 is disposed along the extending direction of the guide platform 131, the guide portion 132 is fixed by a fixing bar 136 located at one side thereof, and the guide portion 132 is located above the table top of the guide platform 131.

In the present invention, as shown in fig. 17, a guide bar 133 is formed at the bottom of the guide portion 132, the guide bar 133 is aligned with the extending direction of the guide portion 132, the lower end of the guide bar 133 forms a certain distance with the table top of the guide platform 131, and the distance is set as follows: higher than the level of the flat side 402 of the collar 400, and thus allows the flat side 402 of the collar 400 to pass under the guide bar 133.

In the present invention, the first guide groove 122 of the guide part 120 is formed on the groove wall of the sink groove 121 closer to the guide bar 133, and the second guide groove 123 is formed on the other groove wall of the sink groove 121. As such, when the collar 400 is ejected from the port at the second end of the guide portion 120 and falls onto the guide land 131, the guide groove 404 of the collar 400 substantially corresponds to the guide bar 133, and the warp side 401 faces the guide bar 133.

As shown in fig. 10 and 11, a pad 139 is provided at the first end of the guide platform 131, the pad 139 being flush with the table top of the guide platform 131, and the collar 400 ejected from the guide 120 falls onto the pad 139. At the port of the second end of the guide 120, a stopper 1392 is provided, the stopper 1392 being driven by a cylinder 1393 mounted at the bottom of the pad 139 such that the stopper 1392 protrudes above the pad 139 for restricting ejection of the collar 400 from the port of the guide 120 and allowing the collar 400 to be ejected from the port to fall into the pad 139 by retracting below the pad 139. A mounting hole is provided in the area of the pad 139 that is shielded by the falling collar 400, and a sensor 1391 (e.g., an infrared sensor) is provided through the mounting hole, and the sensor 1391 is used to sense whether the collar 400 is present on the pad 139, for example, when the infrared rays emitted by the infrared sensor 1391 are shielded, to indicate that the collar 400 is present on the pad 139. When the sensor 1391 senses that the retainer ring 400 exists on the pad 139, the cylinder 1393 for driving the limit post 1392 enables the limit post 1392 to extend, further the port of the guide portion 120 is limited to continuously discharge the retainer ring 400, and when the sensor 1391 does not sense that the retainer ring 400 exists on the pad 139, the cylinder 1393 enables the limit post 1392 to retract, and the port of the guide portion 120 discharges the retainer ring 400 to fall onto the pad 139. Thus, the cooperation of the stop posts 1392 with the sensor 1391 serves to enable only one collar 400 to be present on the pad 139 and not two collars 400 at the same time.

As shown in fig. 10, 13 and 14, the correction mechanism 140 is located above the junction between the guide portion 120 and the guide platform 131, the correction mechanism 140 includes a ram 141 and a cylinder 142 for driving the ram 141, the ram 141 faces vertically toward the collar 400 located on the pad 139, a "one-line" shaped protruding strip 1411 is formed at the bottom of the ram 141, the protruding strip 1411 and the guide strip 133 at the bottom of the guide portion 132 are located on the same vertical platform, and both sides of the protruding strip 1411 are formed with chamfer surfaces so that the thickness of the protruding strip 1411 increases gradually from bottom to top. After the collar 400 falls onto the pad 139, the cylinder 142 drives the ram 141 to move downward so that the protruding strips 1411 vertically extend into the guide grooves 404 of the collar 400, and the ram 141 is reset by the cylinder 142, in this process, the lower ends of the protruding strips 1411 extend into the guide grooves 404 due to the smaller thickness, and have a corrective action on the clamping grooves along with the continuous extension, and the action is that: the guide slot 404 is aligned exactly with the guide bar 133.

As shown in fig. 15, 16, 18, 19, the driving mechanism is located on one side of the first end of the guide platform 131 and is opposite to the guide platform 131. The driving mechanism includes: cylinder 134, slide 1343, slider 1342, and push plate 135.

The slide rail 1343 is mounted on the guide platform 131 at one side of the guide 132, and the slide rail 1343 is strictly parallel to the guide 132; the slide 1342 is mounted on the slide rail 1343 on the one hand and is capable of sliding along the slide rail 1342, and on the other hand, the slide rail 1342 is connected to the head of the piston rod 1341 of the air cylinder 134, so that the air cylinder 134 drives the slide rail 1342 to slide along the slide rail 1343 via the piston rod 1341.

As shown in fig. 10, the pusher plate 135 is fixed to one side of the slider 1342 such that the pusher plate 135 is opposite the guide 132, such that the head of the pusher plate 135 is opposite the flat side 402 of the collar 400 on the pad 139, and an arcuate notch 1351 is machined in the head of the pusher plate 135, the arcuate notch 1351 matching the outer edge of the flat side 402 of the collar 400. Thus, after the collar 400 falls into the pad 139, the piston rod 1341 of the air cylinder 134 extends to drive the pushing plate 135 to push against the flat side 402 of the collar 400, so that the collar 400 slides into the guide bar 133 quickly, that is, the guide bar 133 slides into the guide groove 404 of the collar 400, and interference with the flat side 402 of the collar 400 can be avoided due to a certain distance between the lower end of the guide bar 133 and the guide platform 131, as shown in fig. 18, and finally the collar 400 is transported from the first end of the guide platform 131 to the outer side of the second end of the guide platform 131, that is, to a designated position by the pushing action of the pushing plate 135.

The advantages of the guide mechanism 130 described above are:

The arrangement, structure, and placement of the guide strips 133 enable the collar 400 to be transported to a designated location without changing attitude (or maintaining a constant attitude).

In some preferred embodiments, the second end of the guiding platform 131 is further provided with a mounting bracket 138, and the mounting bracket 138 and the slider 1342 are provided with a mating travel switch 137, which is used to form a switch: when the piston rod 1341 is extended to carry the collar 400 to a designated position by means of the push plate 135, the mating switch is contacted to signal the valve means controlling the extension and retraction of the cylinder 134, which valve means, after signal, retracts the piston rod 1341 of the cylinder 134 by changing the air passage to the cylinder 134, in preparation for pushing against the next collar 400 that falls onto the pad 139.

Tool mechanism 200

As shown in fig. 20 to 31, the tool mechanism 200 is configured such that a collar 400 to be transported to a specified position (a side of the second end of the guide table 131) by the transport mechanism 100 is mounted on a cylinder 501 of the brake pad 500. As shown in fig. 20, the tooling mechanism 200 is disposed on the second end side of the guide platform 131, i.e., on the side of the above-mentioned designated position, as shown in fig. 31, above the brake pad 500 to which the collar 400 is to be mounted.

The tooling mechanism 200 includes: the press-fitting mechanism 210 and the driving mechanism. The driving mechanism is located above the press-fitting mechanism 210 and is used for driving the press-fitting mechanism 210 to vertically move toward the cylinder 501 of the brake pad 500.

As shown in fig. 23, the tooling mechanism 200 includes: a holding member 212, an actuating member 211, a coupling member 214, a punch pin 213, a spring 215, and a guide pin 216.

As shown in fig. 20 and 21, the driving mechanism includes a cylinder 220 and a mounting plate 230, the cylinder 220 is fixed above the mounting plate 230, a piston rod of the cylinder 220 passes through the mounting plate 230, and a head of the piston rod is connected to the holding member 212 via a flange post 221.

The coupling member 214 is disposed below the holding member 212, and the actuating member 211 is disposed below the holding member 212 and coupled to the holding member 212 by a fastener. Preferably, the holding member 212, the coupling member 214, and the actuating member 211 have a substantially disk-like shape (or flat column-like shape).

In the present invention, as shown in fig. 24 to 26, a guide cavity 2171 penetrating in the axial direction is provided in the middle of the actuating member 211, and a guide rib 2172 is formed in the guide cavity 2171, and the guide ribs 2172 extend axially to a length outside both ends of the actuating member 211.

As shown in fig. 23, a through groove 2175 is formed at the interface of the actuating member 211 and the coupling member 214, the through groove 2175 extends radially inward from the coupling member 214 (or the actuating member 211) to the guide cavity 2171, a guide bar 2176 is formed on the top wall of the through groove 2175, the guide bar 2176 is opposite to the guide rib 2172 in the guide cavity 2171, and the guide bar 2176 also has a predetermined distance from the bottom wall of the through groove 2175 to allow the flat side 402 of the collar 400 to pass through, so that the collar 400 is allowed to enter the through groove 2175 from the outside of the through groove 2175, and the guide bar 2176 in the through groove 2175 can guide the collar 400 just as the guide bar 133 under the guide portion 132 so that the collar 400 slides into the guide cavity 2171 in the posture of the warp side 401 toward the guide rib 2172, and the guide rib 2172 is inserted into the guide groove 404 after the collar 2172 slides into the guide cavity 2171.

In the present invention, as shown in fig. 23 and 24, the upper end of the guide cavity 2171 is extended upward by a length to form a sheath 2177 for allowing the snap groove from the upper end surface of the actuating member 211 to be accurately slid into the guide cavity 2171.

A mounting hole 218 is also radially provided in the actuating member 211, which mounting hole 218 also extends through to the guide cavity 2171, and a sensor 219 is inserted into the mounting hole 218, which sensor 219 is adapted to sense whether the collar 400 is slid into the guide cavity 2171.

As shown in fig. 27 and 28, the upper end of the punch 213 is coaxially connected to the holding member 212 by means of a fastener, the lower end of the punch 213 is coaxial with the guide cavity 2171 of the actuating member 211 and faces the guide cavity 2171, the outer peripheral region of the punch 213 corresponding to the guide rib 2172 is formed with a relief groove 2131, the relief groove 2131 penetrates both ends of the punch 213, so that the punch 213 can be extended into the guide cavity 2171 by the relief groove 2131 to the guide rib 2172 and the lower end can be penetrated from the lower end of the guide cavity 2171.

As shown in fig. 28, the guide rib 2172 below the upper end surface of the actuator 211 has opposite tapered surfaces 2173 and cylindrical surfaces 2174 formed on both sides, the cylindrical surfaces 2174 being positioned below the tapered surfaces 2173, the lower ends of the tapered surfaces 2173 being joined to the upper ends of the cylindrical surfaces 2174, and the lower ends of the cylindrical surfaces 2174 extending to the lower ends of the guide rib 2172. Thus, as collar 400 entering guide cavity 2171 slides down past tapered surface 2173, as shown in FIGS. 29 and 30, ring portion 405 in the middle of collar 400 expands under the action of tapered surface 2173.

It will be appreciated that the walls of the relief groove 2131 of ram 213 need to be configured as an arcuate concave surface that mates with cylindrical surface 2174 so that the lower end of ram 213 can move smoothly through actuating member 211 to the lower end of guide rib 2172 as it moves downward.

With the above structure, the punch pin 213 can push pledge against a loan down along the guide rib 2172 from the collar 400 having the through groove 2175 entered the guide cavity 2171 when moving downward relative to the actuating member 211, and the collar 400 is expanded after passing the tapered surface 2173 by the pushing action of the punch pin 213, and the ring 405 is kept expanded when passing the cylindrical surface 2174, so that the collar 400 can be in a condition of being able to fit over the cylinder 501 of the brake shoe 500.

The springs 215 (the springs 215 in the drawing are indicated by the generally columnar shape because in actual drawing, the columnar structure shape occupies less data on the drawing) include a plurality of springs 215 which are circumferentially distributed around the punch pin 213, each spring 215 being interposed between the holding member 212 and the engaging member 214, and the springs 215 being set in a slightly pressed state.

As shown in fig. 23, the guide posts 216 include a plurality of guide posts 216 circumferentially distributed around the punch posts 213, the lower end of each guide post 216 is fixedly connected to the coupling member 214, the upper end of the guide post 216 passes through the holding member 212, and the upper end of the guide 132 is provided with a sleeve-shaped restricting member 2161 for restricting the upper end of the guide post 216 from being released from the holding member 212.

Under the action of the guide post 216, the punch post 213 passes through the guide cavity 2171 of the actuating member 211 more tightly without radial play.

The function of the spring 215 is: after the lower end of ram 213 passes out of the lower end of guide cavity 2171, spring 215 may return ram 213 to the upper end of guide cavity 2171.

In the present invention, the guide mechanism 130, the tool mechanism 200, and the brake pad 500 in the conveying mechanism 100 are arranged in the following positional relationship:

as shown in fig. 20 and 21, the tooling mechanism 200 located at the second end (designated position) side of the guide platform 131, after the piston rod of the cylinder 220 drives the press-fit mechanism 210 to move up, the through groove 2175 of the press-fit mechanism 210 is horizontally opposite to the second end of the guide platform 131, and the guide bar 2176 in the through groove 2175 is strictly opposite to the guide bar 133 at the bottom of the guide portion 132, as shown in fig. 29 and 30, while after the piston rod of the cylinder 220 drives the press-fit mechanism 210 to move down, the lower end of the guide rib 2172 on the actuating member 211 can abut against the upper end of the cylinder 501 of the brake pad 500, and the retaining member 212 drives the ram 213 to move down continuously under the continued driving of the piston rod so that the ram 213 pushes the clamp groove past the guide rib 2172 and finally comes out from the lower end of the guide rib 2172.

The following describes the working procedure of the cooperation of the conveying mechanism 100 and the tooling mechanism 200:

The feeder 110 in the conveying mechanism 100 causes the collar 400 to be ejected from the port of the spiral groove 112 and enter onto the sinking groove 121 of the guide part 120, the collar 400 passes through the guide part 120 in a certain posture by the action of the two guide grooves of the sinking groove 121, the collar 400 passing through the guide part 120 falls from the port of the second end of the guide part 120 onto the pad 139 on the second end side of the guide platform 131 (whether or not the collar 400 falls into the gasket is judged by the sensor 139, the judgment method has been described above), at this time, the guide groove 404 of the collar 400 falling into the pad 139 is substantially opposed to the guide bar 133 of the bottom of the guide part 132, then the ram 141 of the correction mechanism 140 located above the pad 139 is moved downward by the driving of the cylinder 1393, so that the convex bar 1411 of the lower end of the ram 141 is inserted into the guide groove 404 of the collar 400 and then moved upward to be reset, and the posture of the collar 400 is corrected so that the guide groove 404 and the guide bar 133 of the bottom of the guide part 132 are strictly lower end; then, the cylinder 134 of the guiding mechanism 130 drives the slide block 1342 connected to the head thereof by the piston rod 1341, the slide block 1342 drives the push plate 135 positioned at one side thereof to push the collar 400 to move towards the direction of the guiding strip 133 of the guiding part 132, so that the guiding groove 404 of the collar 400 slides into the guiding strip 133 at the bottom of the guiding part 132, the collar 400 is pushed to the second end of the guiding platform 131 under the guiding of the guiding strip 133, and finally the collar 400 is ejected from the second end of the guiding platform 131; and when the piston rod 1341 of the cylinder 134 of the guide mechanism 130 pushes against the collar 400 to be ejected from the second end of the guide platform 131, the slider 1342 of the head of the piston rod 1341 contacts the mating travel switch 137 on the mounting bracket 138 of the second end of the guide platform 131, thereby retracting the piston rod 1341 back to rest in preparation for pushing against the collar 400 on the next pad 139 that falls into the second end of the guide platform 131.

Because the through groove 2175 of the press-fitting mechanism 210 is located on the side of the second end of the guide platform 131, the collar 400 ejected from the second end enters the through groove 2175 and enters the guide cavity 2171 of the actuation member 211 under the guide of the guide bar 2176 in the through groove 2175, and at the same time, the guide rib 2172 in the guide cavity 2171 is inserted into the guide groove 404 of the collar 400 slid into the guide cavity 2171; but it should be noted that: whether the retainer ring 400 slides into the guide cavity 2171 is judged by a sensor 219 installed in the actuating member 211 and facing the guide cavity 2171, when the sensor 219 judges that the retainer ring 400 slides into the guide cavity 2171, the cylinder 220 of the tool mechanism 200 extends out the piston rod, so that the whole press-fit mechanism 210 is driven to move downwards towards the brake pad 500, and finally the lower end of the guide rib 2172 of the actuating member 211 is abutted against the upper end of the cylinder 501 of the brake pad 500.

After the lower end of the guide rib 2172 abuts against the upper end of the cylinder 501 of the brake pad 500, as shown in fig. 30, the piston rod continues to extend, at this time, the actuating member 211 does not move down, and the holding member 212 drives the plunger 213 to move down, so that the lower end of the plunger 213 pushes down against the collar 400 in the guide cavity 2171, during which the collar 400 expands through the tapered surface 2173 on the guide rib 2172 and is held in the expanded state through the tapered lower cylindrical surface 2174, and finally the plunger 213 pushes the collar 400 in the expanded state out of the lower end of the guide rib 2172, thereby causing the collar 400 to slide into the cylinder 501 in the expanded state and finally fit over the annular mounting groove 5011 of the cylinder 501 by free retraction.

After the collar 400 is sleeved on the cylinder 501 of the brake pad 500 by the punch 213, the cylinder 220 of the tooling mechanism 200 retracts the piston rod, so that the press-fitting mechanism 210 moves upwards, as shown in fig. 21, and finally moves upwards to a position where the through groove 2175 is opposite to the guide platform 131 again, and in the process again, the punch 213 retracts to a position where the lower end of the punch 213 is located at the upper end of the guide cavity 2171 under the action of the spring 215, so that the next collar 400 is ready for being installed.

In some preferred embodiments, as shown in fig. 26, the lower end of the guide rib 2172 is formed with a positioning taper 21721, as shown in fig. 5, the positioning taper 21721 is configured to mate with a taper 5012 on the upper end of the post 501, thereby positioning the wire rib and the post 501 when the guide rib 2172 abuts against the upper end of the post 501.

In some preferred embodiments, as shown in fig. 26, a limit bar 2172 is formed at the lower end of the guide rib 2172 at a position corresponding to the two extension sections 403 of the collar 400. Thus, after the lower end of the guiding rib 2172 abuts against the upper end of the column 501, as shown in fig. 30, the limit bar 21782 extends to a section below the upper end surface of the column 501; the limit bar 217422 has a chamfer that gradually reduces the thickness of the limit bar 217422 from top to bottom. After the collar 400 is pushed by the punch pin 213 to be separated from the lower end of the guide rib 2172, the limit bar 217422 is still located in the guide groove 404 of the collar 400, and the expansion of the collar 400 is not suddenly disappeared under the limit of the limit bar 217422, so that the expansion degree is gradually reduced, and further, the impact of the collar 400 on the column 501 caused by sudden reset after the collar 400 is sleeved on the column 501 is avoided, and the impact on the column 501 is further caused, so that the brake pad 500 vibrates and generates noise.

In some preferred embodiments, a length of sheath 2178 extends downwardly at the lower end of the actuator 211 such that the guide cavity 2171 extends below the actuator 211, thereby providing some protection to the collar 400

As shown in fig. 32 to 37, the moving mechanism 300 includes a horizontal moving mechanism 310 for adjusting the horizontal position of the brake pad 500 and a lifting mechanism 320 for conveying the brake pad 500 onto the horizontal moving mechanism 310 and conveying the brake pad 500 away from the horizontal moving mechanism 310.

Based on the above structure of the horizontal moving mechanism 310, when the brake pad 500 is placed on the longitudinal moving platform 3121 by the positioning tool mechanism 330, the horizontal position of the brake pad 500 can be adjusted by the first driving mechanism and the second driving mechanism, so that each column 501 on the brake pad 500 can be aligned with the tool mechanism 200, and then each column 501 on the brake pad 500 is provided with the collar 400 by the tool mechanism 200.

As shown in fig. 35, two slide rails extending in the lateral direction are provided at the upper end of the upper frame 602, and the lifting mechanism 320 includes a clamping mechanism 321, and a third driving mechanism and a fourth driving mechanism.

The clamping mechanism 321 is lapped on the sliding rail by virtue of the sliding plate 3214, and the sliding plate 3214 drives the clamping mechanism 321 to transversely move by virtue of the sliding block matched with the sliding rail.

The third driving mechanism is a cylinder 3213 provided on the slide plate 3214, and a piston rod of the cylinder 3213 penetrates out of the slide plate 3214 downward to be connected to a cylinder 3211 of the clamping mechanism 321, which enables vertical movement of the positioning fixture mechanism 330 clamped by the clamping jaw 3212.

The fourth driving mechanism is, for example, a screw disposed at the upper end of the upper frame 602 for driving the slide plate 3214 on the clamping mechanism 321 so that each clamping mechanism 321 can move from side to side in the lateral direction.

The following describes the operation of the moving mechanism 300:

The clamping mechanism 321 is moved to above the positioning fixture mechanism 330 provided by the external assembly line and provided with the brake pads 500 by using the fourth driving mechanism, then the clamping mechanism 321 is moved downwards by using the air cylinder 3213 as the third driving mechanism to clamp the positioning fixture mechanism 330, then the positioning fixture mechanism 330 is moved longitudinally towards the direction of the horizontal moving mechanism 310 by being driven by the fourth driving mechanism, and when the positioning fixture mechanism 330 is conveyed to above the longitudinal moving platform 3121 of the horizontal moving mechanism 310, the positioning fixture mechanism 330 is moved downwards by using the third driving mechanism to be placed on the longitudinal moving platform 3121; then, the horizontal moving mechanism 310 is used to adjust the horizontal position of the positioning tool, so that each cylinder 501 of the brake pad 500 is sequentially opposite to the press-fitting mechanism 210 of the tool mechanism 200, and the cylinders 501 are sequentially loaded into the collar 400 by the press-fitting mechanism 210. After the collars 400 are mounted on all the columns 501 on the brake pad 500, the clamping mechanism 321 transports the positioning tool mechanism 330 on the longitudinal moving platform 3121 by means of the third driving mechanism and the fourth driving mechanism, and the subsequent clamping mechanism 321 continuously transports the subsequent brake pad 500 to be assembled to the longitudinal moving platform 3121, thereby realizing continuous assembly of the brake pad 500 and further forming an automatic assembly line.

The positioning tooling mechanism 330 specifically includes: a base plate 331 and a work plate.
