Description

Technical Field

[0001] The invention relates to the technical field of brake pad blanking, and in particular to a brake pad product detection and blanking device. Background Art

[0002] At present, brake pads are important safety components of vehicle braking systems, which directly affect the braking performance of vehicles. Brake pads in the prior art are generally composed of steel plates, friction blocks and ear seats. The side of the steel plate is connected to the friction block by bonding a heat insulation layer, and two ear seats are respectively installed at both ends of the steel plate. Due to the irregular shape of the brake pads, manual operation is required for the unloading of the brake pads during testing, which is difficult to meet the needs of automated testing.

[0003] In order to solve the above problems, the patent with the authorization announcement number CN206203409U discloses an automatic unloading device for brake pad product detection, including an unloading combined skateboard, the unloading combined skateboard is composed of a skateboard and a vertical rectangular plate, the skateboard of the unloading combined skateboard is provided with two parallel and symmetrical first gaskets, the upper parts of the two first gaskets are provided with two parallel and symmetrical second gaskets, the upper parts of the two second gaskets are provided with two parallel and symmetrical brake pad guide cylinders, the brake pad guide cylinders guide the brake pads smoothly, a unloading port is provided on the vertical rectangular plate of the unloading combined skateboard, a cylinder is provided above the unloading port, a brake pad baffle is welded on the cylinder, the cylinder is connected to an air source, an electromagnetic magnet is provided on the vertical rectangular plate of the unloading combined skateboard, and the electromagnetic magnet is connected to a power supply;

[0004] Although this patent solves the problem of automatic unloading of brake pads, the following defects still exist: before unloading, the brake pad is in the unloading port with only one side facing outward, and after unloading, the brake pad will fall over due to its own irregular shape, which is not conducive to detecting the brake pad from multiple angles. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a brake pad product detection and unloading device, which can enable the brake pads to be unloaded in an orderly and smooth manner. The brake pads remain in a vertical state after unloading and are conveyed along a chain. The brake pads can turn during the conveying process, which is conducive to detecting the brake pads from multiple angles. The detected defective products can be magnetically absorbed by the brake pad defective unloading mechanism, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a brake pad product detection and unloading device, comprising a seat plate, and also comprising:

[0007] The transmission gear of the present invention is connected with the transmission gear of the present invention one by one, and the transmission gear of the present invention is connected with the transmission gear of the present invention to the transmission gear of the present invention is connected with the transmission gear of the present invention to the transmission gear of the present invention. On the upper side, the inner tops of the two chains are respectively matched and connected to the tops of the two support and discharge sprockets, and the two support and discharge sprockets are fixedly connected to the longitudinal support and discharge shaft, and the two ends of the support and discharge shaft are rotatably connected to the tops of the two support brackets through bearings, and the bottom ends of the two support brackets are respectively fixedly connected to the upper side of the seat plate, and each support and discharge sprocket is respectively located between the driven sprocket and the flattening sprocket, and the horizontal position of the top of the support and discharge sprocket is higher than the top of the driven sprocket. The bottom of the flattening sprocket is arranged horizontally corresponding to the top of the driving sprocket, the driven sprocket and the driving sprocket have the same size and height, the supporting and unloading sprocket and the flattening sprocket make the upper left end of the chain in an inverted V-shaped state and the upper right end of the chain in a horizontal state. Specifically, the supporting and unloading sprocket is used to support the upper left end of the chain upward, so that the upper left end of the chain is in an inverted V-shaped state, and the flattening sprocket limits the upper middle part of the chain, so that the upper right end of the chain is in a horizontal state;

[0008] The brake pad follower longitudinal movement mechanism is installed on the material unloading mounting frame, and the brake pad follower longitudinal movement mechanism is respectively installed with a follower steering mechanism for brake pad detection and a brake pad unloading supporting mechanism;

[0009] The brake pad unloading rack installation mechanism is installed on the rear side of the left end of the seat plate, and the brake pad unloading rack is installed on the brake pad unloading rack installation mechanism.

[0010] Furthermore, the brake pad follower longitudinal movement mechanism includes a longitudinal movement groove, a longitudinal movement support block, a return spring, a rotating shaft, a rectangular bracket, a longitudinal support rod and a trapezoidal plate. The unloading mounting frame is provided with a longitudinal movement groove, and the longitudinal movement support block is slidably connected in the longitudinal movement groove. The front and rear sides in the longitudinal movement groove are respectively connected to the front and rear sides of the longitudinal movement support block through two return springs. The middle part of the longitudinal movement support block is rotatably connected to the rotating shaft through a bearing. The front side of the seat plate is located at the right side of the flattening sprocket and is fixedly connected to the rectangular bracket by screws. The rear side of the top of the rectangular bracket is fixedly connected to the front side of the horizontal trapezoidal plate through the longitudinal support rod. The left and right sides of the trapezoidal plate are both inclined surfaces, and the rear length of the trapezoidal plate is smaller than the front length of the trapezoidal plate. The trapezoidal plate is close to the inner top of the chain, and the bottom end of the rotating shaft between the tops of the right ends of the two chains is horizontally arranged corresponding to the trapezoidal plate.

[0011] Furthermore, the brake pad follower longitudinal movement mechanism also includes a rolling wheel, and one end of the rotating shaft near the inner middle of the chain is rotatably connected to the rolling wheel. Since the contact between the rotating shaft and the trapezoidal plate is frictional contact, it is easy for the rotating shaft and the trapezoidal plate to be worn. The rotating shaft is connected to the side of the trapezoidal plate in a rolling manner with the help of the rolling wheel, and the frictional contact between the rotating shaft and the trapezoidal plate is changed to rolling contact, thereby reducing the wear on the rotating shaft and the trapezoidal plate.

[0012] Furthermore, the brake pad unloading support mechanism includes a unloading support seat, an arc bracket groove, a magnetic block and a supporting bar, the end of the rotating shaft away from the inner middle part of the chain is fixedly connected to the unloading support seat, an arc bracket groove is provided on the unloading support seat, a magnetic block is arranged on one side of the arc bracket, and a supporting bar is arranged on the side of the unloading support seat away from the magnetic block.

[0013] When the unloading support seat moves gradually to the upper right along the left side of the inverted V-shaped part of the chain, the arc bracket cooperates with the bottom of the steel plate of the rightmost brake pad in the brake pad unloading rack, the magnetic block magnetically attracts the bottom of the steel plate of the brake pad, and the supporting bar also supports the bottom of the friction block of the brake pad, so that the brake pad is stably supported, ensuring that the brake pad is in a vertical state to complete the unloading operation from the brake pad unloading rack.

[0014] Furthermore, the follow-up steering mechanism for brake pad detection includes a bottom rod, a longitudinal rack and a follow-up gear. The shaft section between the rolling wheel and the longitudinal displacement support block is fixedly sleeved with a follow-up gear. The side of the unloading mounting frame is fixedly connected to the two ends of the longitudinal rack through two bottom rods, and the longitudinal rack is meshed with the follow-up gear. When the longitudinal displacement support block moves backward along the longitudinal displacement groove, the follow-up gear moves backward relative to the longitudinal rack. Since the longitudinal rack is fixed to the unloading mounting frame through the bottom rod, the follow-up gear will drive the shaft to rotate counterclockwise. When the rolling wheel rolls with the rear side of the trapezoidal plate, the shaft rotates counterclockwise by ninety degrees, so that the friction block on the steel plate faces backward. The friction block on the steel plate can be fully detected by the brake pad detection equipment on the rear side. When the longitudinal displacement support block moves forward along the longitudinal displacement groove, the shaft rotates clockwise due to the cooperation of the follow-up gear and the longitudinal rack. When the rolling wheel is separated from the trapezoidal plate, the follow-up gear and the longitudinal rack cooperate to restore the shaft to the initial state, that is, the brake pad is in the longitudinal state.

[0015] Furthermore, the brake pad unloading rack installation mechanism includes a lifting assembly, a lifting platform, a quick-release clamping and locking assembly, a quick-release plate and a positioning column. The lifting platform is installed on the left rear side of the seat plate through the lifting assembly. A slot is provided at the upper front end of the lifting platform. A positioning column is provided in the slot. The rear end of the quick-release plate is clamped with the slot, and the positioning hole on the quick-release plate is connected with the positioning column. A quick-release clamping and locking assembly is installed on the upper side of the lifting platform. The lifting assembly is used to drive the lifting platform to move up and down. When the lifting platform moves up, the brake pad unloading rack also rises with the quick-release plate. At this time, the brake pads in the brake pad unloading rack will not be supported and taken away by the brake pad unloading supporting mechanism, and the device can be controlled to stop unloading. The positioning column is used to stably clamp the quick-release plate in the slot. The quick-release clamping and locking assembly is used to quickly install the quick-release plate and the lifting platform, which is convenient for quick replacement of the quick-release plate and the brake pad unloading rack.

[0016] Furthermore, the quick-release clamping locking assembly includes a side strip, a locking plate, a handle, a spring support block and a locking spring. The left and right ends of the upper side of the lifting platform are respectively fixedly connected to two side strips, and limiting grooves are respectively provided on the two side strips. The two ends of the locking plate are respectively connected to the two limiting grooves for longitudinal sliding. A handle is installed on the top of the locking plate, and the rear side of the locking plate is connected to the spring support block through a locking spring. The spring support block is fixed on the lifting platform, and the front bottom of the locking plate corresponds to the upper side of the rear end of the quick-release plate.

[0017] Furthermore, the brake pad unloading rack includes an unloading side plate, a connecting rod, an unloading guide groove, a discharge trough and a placement guide notch. The front end of the quick-release plate is fixedly connected to a unloading side plate, and the unloading side plate is tilted with the left side higher and the right side lower. The top of the unloading side plate is connected to another unloading side plate through two connecting rods, and the right end of the unloading side plate is located on the upper side of the unloading sprocket that supports the unloading. Unloading guide grooves are respectively provided at the bottom of the side where the two unloading side plates are close to each other, and the right end of each unloading guide groove is bent to the upper right to form a discharge trough, and placement guide notches are respectively provided at the left ends of the side where the two unloading side plates are close to each other, and the bottom of each placement guide notch is respectively connected to the upper side of the left end of the unloading guide groove.

[0018] Furthermore, it also includes a mechanism for unloading defective brake pads, which includes a unloading platform, a movable seat, a rotation control component, a telescopic control component, a rocker arm, an unloading mounting plate, a brake pad upper support rod, an electromagnet and a defective unloading trough body, the top of the rectangular bracket is fixedly connected to the unloading platform, the unloading platform is fixedly connected to the movable seat, the movable seat is connected to one end of the rocker arm through the rotation control component, the other end of the rocker arm is connected to the unloading mounting plate through the telescopic control component, an electromagnet is installed in the middle circular groove of the unloading mounting plate, two brake pad upper support rods are fixedly connected to both sides of the end of the unloading mounting plate away from the chain, and the front end of the unloading platform is connected to the defective unloading trough body.

[0019] Furthermore, it also includes an orderly collection mechanism for brake pads, which includes a collection box tilted limit bracket, a brake pad collection box, an ear seat limit collection groove and a brake pad collection support rod, the right end of the seat plate is equipped with a collection box tilted limit bracket, a brake pad collection box tilted higher on the left and lower on the right is placed on the collection box tilted limit bracket, a collection opening is provided at the left end of the brake pad collection box, and ear seat limit collection grooves are respectively provided on the front and rear sides of the top of the brake pad collection box, and a brake pad collection support rod is provided at the left end of the brake pad collection box corresponding to the bottom of the ear seat limit collection groove.

[0020] Compared with the prior art, the beneficial effects of the brake pad product testing and unloading device are:

[0021] 1. Place multiple brake pads to be unloaded in the brake pad unloading rack, and the conveying motor drives the driving shaft to rotate clockwise, and the driving shaft drives the two driving sprockets to rotate clockwise. The chain is installed with the help of the driven shaft and the driven sprocket. The rotation of the driving sprocket makes the two chains rotate clockwise, and the multiple unloading mounting frames between the two chains also move with the chain. The unloading mounting frame can drive the brake pad follower longitudinal movement mechanism, the follower steering mechanism for brake leather detection and the brake pad unloading supporting mechanism to move, when the unloading mounting frame, the brake pad follower longitudinal movement mechanism, the follower steering mechanism for brake leather detection and the brake pad unloading supporting mechanism gradually move to the upper right along the left side of the inverted V-shaped part of the chain. When the brake pad unloading supporting mechanism approaches the top of the inverted V-shaped part of the chain, the top of the brake pad unloading supporting mechanism supports the bottom of a brake pad at the rightmost end of the brake pad unloading rack. With the operation of the chain, the brake pad can be unloaded in an orderly and stable manner.

[0022] 2. When the unloading support seat moves gradually to the upper right along the left side of the inverted V-shaped part of the chain, the arc bracket cooperates with the bottom of the steel plate of the rightmost brake pad in the brake pad unloading rack, the magnetic block magnetically attracts the bottom of the steel plate of the brake pad, and the supporting bar also supports the bottom of the friction block of the brake pad, so that the brake pad is stably supported, ensuring that the brake pad is in a vertical state to complete the unloading operation from the brake pad unloading rack.

[0023] 3. The backward movement of the longitudinal support block drives the brake pad unloading supporting mechanism and the brake pad to move backward, so that the brake pad can be close to the brake pad detection equipment located at the rear side. The follow-up steering mechanism for brake pad detection can rotate the brake pad unloading supporting mechanism and the brake pad. The brake pad can turn during the transportation process, which is conducive to the detection of the brake pad from multiple angles.

[0024] 4. When the brake pad detection equipment detects that the brake pad is defective, the conveying motor stops working. At this time, the friction block in the brake pad detected as defective faces the rear side, and the rotary control component drives the swing arm to swing backward until the swing arm is in a horizontal state. Then the telescopic control component drives the unloading mounting plate to move backward relative to the swing arm. The rear side of the unloading mounting plate is close to the front side of the steel plate in the brake pad. The two brake pad upper support rods are at the bottom of the two ear seats on the steel plate. The electromagnet works to magnetically attract the steel plate, and the steel plate is close to the rear side of the unloading mounting plate. Then the rotary control component drives the swing arm to swing forward. The two brake pad upper support rods lift the two ear seats upward to allow the steel plate to separate from the magnetic block in the arc bracket. The swing arm continues to swing forward until the swing arm is in a horizontal state. The electromagnet stops working, and the brake pad falls downward due to gravity and falls onto the defective unloading trough body, completing the unloading of the defective brake pad.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For example, see Figures 1 to 10 , this embodiment provides a technical solution: a brake pad product detection and unloading device, including a seat plate 1, and also including an unloading conveying mechanism 2, a brake pad follower longitudinal movement mechanism 5 and a brake pad unloading rack installation mechanism 3;

[0038] The material discharging and conveying mechanism 2 comprises a driven shaft 22, a driven sprocket 23, a driving shaft 25, a driving sprocket 26, a conveying motor 27, a chain 28, a flattening bracket 29, a flattening sprocket 210, a support bracket 211, a support material discharging shaft 212, a support material discharging sprocket 213, and a material discharging mounting bracket 214. A longitudinal driven shaft 22 is rotatably mounted on the upper left end of the seat plate 1, and two driven sprockets 23 are fixedly connected to the driven shaft 22. A longitudinal driving shaft 25 is rotatably mounted on the upper right end of the seat plate 1, and two driving sprockets 26 are fixedly connected to the driving shaft 25. The two driving sprockets 26 The two driven sprockets 23 are connected respectively by two chains 28, and a plurality of unloading mounting brackets 214 are arranged at equal distances between the two chains 28. The specific number of the unloading mounting brackets 214 can be selected as needed. The front and rear ends of the unloading mounting brackets 214 are fixedly connected to the front and rear corresponding chain links on the two chains 28, respectively. The end of the driving shaft 25 is fixedly connected to the output shaft of the conveying motor 27. The middle upper sides of the two chains 28 are respectively matched to the bottoms of the two flattening sprockets 210. The two flattening sprockets 210 are respectively rotatably connected to the tops of the two flattening brackets 29 through bearings. The bottom ends of the brackets 29 are respectively fixedly connected to the upper side of the seat plate 1, and the inner tops of the two chains 28 are respectively matched to connect the tops of the two lifting and unloading sprockets 213, and the two lifting and unloading sprockets 213 are both fixedly connected to the longitudinal lifting and unloading shaft 212. The two ends of the lifting and unloading shaft 212 are respectively rotatably connected to the tops of the two lifting brackets 211 through bearings, and the bottom ends of the two lifting brackets 211 are respectively fixedly connected to the upper side of the seat plate 1, and each lifting and unloading sprocket 213 is respectively located between the driven sprocket 23 and the flattening sprocket 210, and the horizontal position of the top of the lifting and unloading sprocket 213 is higher than that of the driven sprocket 23. The top of the sprocket 23 and the bottom of the flattening sprocket 210 are arranged horizontally corresponding to the top of the driving sprocket 26. The driven sprocket 23 and the driving sprocket 26 have the same size and height. The raised unloading sprocket 213 and the flattening sprocket 210 allow the upper left side of the chain 28 to be in an inverted V-shaped state and the upper right side of the chain 28 to be in a horizontal state. Specifically, the raised unloading sprocket 213 is used to prop up the upper left side of the chain 28, so that the upper left side of the chain 28 is in an inverted V-shaped state. The flattening sprocket 210 limits the upper middle side of the chain 28, so that the upper right side of the chain 28 is in a horizontal state.

[0039] Specifically, the unloading conveying mechanism 2 also includes a driven bracket 21 and an active bracket 24. The front and rear ends of the driven shaft 22 are respectively connected to the top ends of the two driven brackets 21 through bearings, and the bottom ends of the two driven brackets 21 are fixedly connected to the seat plate 1. The front and rear ends of the active shaft 25 are respectively connected to the top ends of the two active brackets 24 through bearings, and the bottom ends of the two active brackets 24 are fixedly connected to the seat plate 1. The conveying motor 27 is installed on the corresponding active bracket 24.

[0040] The brake pad follower longitudinal movement mechanism 5 is installed on the material unloading mounting frame 214, and the brake pad follower longitudinal movement mechanism 5 is respectively installed with a brake pad detection follower steering mechanism 6 and a brake pad unloading supporting mechanism 7;

[0041] The brake pad follower longitudinal movement mechanism 5 includes a longitudinal movement groove 51, a longitudinal movement support block 53, a return spring 55, a rotating shaft 56, a rectangular bracket 58, a longitudinal support rod 59 and a trapezoidal plate 510. The unloading mounting frame 214 is provided with a longitudinal movement groove 51, and the longitudinal movement support block 53 is slidably connected in the longitudinal movement groove 51. The front and rear sides of the longitudinal movement groove 51 are respectively connected to the front and rear sides of the longitudinal movement support block 53 through two return springs 55. The middle part of the longitudinal movement support block 53 is rotatably connected to the rotating shaft 56 through a bearing. The front side of the seat plate 1 is located at the front side of the seat plate 1. A rectangular bracket 58 is fixedly connected to the right side of the flattening sprocket 210 by screws, and the rear side of the top of the rectangular bracket 58 is fixedly connected to the front side of the horizontal trapezoidal plate 510 by a longitudinal support rod 59. The left and right sides of the trapezoidal plate 510 are both inclined surfaces, and the rear length of the trapezoidal plate 510 is smaller than the front length of the trapezoidal plate 510. The trapezoidal plate 510 is close to the inner top of the chain 28, and the bottom end of the rotating shaft 56 located between the right end tops of the two chains 28 is horizontally arranged corresponding to the trapezoidal plate 510.

[0042] The brake pad follower longitudinal movement mechanism 5 also includes a longitudinal guide groove 52 and a longitudinal slide block 54. Two longitudinal guide grooves 52 are respectively provided on the left and right sides of the unloading mounting frame 214. The left and right sides of the longitudinal movement support block 53 are respectively fixedly connected to two longitudinal slide blocks 54. The two longitudinal slide blocks 54 are respectively slidably connected to the two corresponding longitudinal guide grooves 52. The longitudinal guide grooves 52 and the longitudinal slide block 54 cooperate to limit the longitudinal movement support block 53, so that the longitudinal movement support block 53 can stably move forward and backward along the longitudinal movement groove 51.

[0043] It also includes a detection support frame 11 and a detection platform 12. The detection support frame 11 is fixedly connected to the rear side of the seat plate 1 by screws, and the top of the detection support frame 11 is fixedly connected to the detection platform 12. The upper side of the detection platform 12 is flush with the upper side of the right end of the chain 28, and the detection platform 12 is located directly behind the rectangular bracket 58. The detection platform 12 is used to install brake pad detection equipment.

[0044] When the unloading mounting bracket 214 is located at the horizontal part of the top right end of the two chains 28, the rotating shaft 56 is in a vertical state, and the unloading mounting bracket 214 continues to move to the right with the operation of the chain 28. When the bottom of the rotating shaft 56 is in friction contact with the left inclined surface of the trapezoidal plate 510, the left inclined surface of the trapezoidal plate 510 pushes the rotating shaft 56 and the longitudinal moving support block 53 to move backward along the longitudinal moving groove 51. At this time, the return spring 55 on the rear side of the longitudinal moving support block 53 is compressed, and the return spring 55 on the front side of the longitudinal moving support block 53 is stretched. When the bottom of the rotating shaft 56 contacts the rear side of the trapezoidal plate 510, the longitudinal moving support block 53 stops moving backward, and the longitudinal moving support block 53 stops moving backward. The backward movement of the support block 53 drives the brake pad unloading supporting mechanism 7 and the brake pad 10 to move backward, allowing the brake pad 10 to be close to the brake pad detection equipment located on the rear side. During the process of frictional contact between the bottom of the rotating shaft 56 and the rear side surface of the trapezoidal plate 510, the brake pad detection equipment completes the detection of the brake pad 10, and then the bottom of the rotating shaft 56 begins to contact the right inclined surface of the trapezoidal plate 510 until the rotating shaft 56 is out of contact with the trapezoidal plate 510. During this process, the two reset springs 55 are gradually reset, allowing the longitudinal movement support block 53 to gradually restore its position to the middle of the longitudinal movement groove 51, and the brake pad 10 also gradually moves forward with the brake pad unloading supporting mechanism 7.

[0045] The brake pad follower longitudinal movement mechanism 5 further includes a rolling wheel 57, and one end of the rotating shaft 56 close to the inner middle of the chain 28 is rotatably connected to the rolling wheel 57. Since the contact between the rotating shaft 56 and the trapezoidal plate 510 is frictional contact, the rotating shaft 56 and the trapezoidal plate 510 are easily worn. The rotating shaft 56 is connected to the side of the trapezoidal plate 510 by rolling with the help of the rolling wheel 57, and the frictional contact between the rotating shaft 56 and the trapezoidal plate 510 is changed to rolling contact, thereby reducing the wear on the rotating shaft 56 and the trapezoidal plate 510.

[0046] The brake pad unloading support mechanism 7 includes a unloading support seat 71, an arc bracket groove 72, a magnetic block 73 and a supporting bar 74. The end of the rotating shaft 56 away from the inner middle part of the chain 28 is fixedly connected to the unloading support seat 71. An arc bracket groove 72 is opened on the unloading support seat 71. A magnetic block 73 is arranged on one side of the arc bracket groove 72. A supporting bar 74 is arranged on the side of the unloading support seat 71 away from the magnetic block 73.

[0047] When the unloading support seat 71 gradually moves toward the upper right along the left side of the inverted V-shaped part of the chain 28, the arc bracket 72 cooperates with the bottom of the steel plate 101 of the rightmost brake pad 10 in the brake pad unloading rack 4, the magnetic block 73 magnetically attracts the bottom of the steel plate 101 of the brake pad 10, and the supporting bar 74 also supports the bottom of the friction block 102 of the brake pad 10, so that the brake pad 10 is stably supported, ensuring that the brake pad 10 is in a vertical state to complete the unloading operation from the brake pad unloading rack 4.

[0048] The follow-up steering mechanism 6 for brake pad detection includes a bottom rod 61, a longitudinal rack 62 and a follow-up gear 63. The shaft section of the rotating shaft 56 located between the rolling wheel 57 and the longitudinal support block 53 is fixedly sleeved with the follow-up gear 63. The side of the unloading mounting frame 214 is fixedly connected to the two ends of the longitudinal rack 62 through two bottom rods 61, and the longitudinal rack 62 is meshedly connected with the follow-up gear 63. When the longitudinal moving support block 53 moves backward along the longitudinal moving groove 51, the follower gear 63 moves backward relative to the longitudinal rack 62. Since the longitudinal rack 62 is fixed to the unloading mounting frame 214 through the bottom rod 61, the follower gear 63 will drive the rotating shaft 56 to rotate counterclockwise. When the rolling wheel 57 rolls in contact with the rear side of the trapezoidal plate 510, the rotating shaft 56 rotates ninety degrees counterclockwise, so that the friction block 102 on the steel plate 101 faces backward. The friction block 102 on the steel plate 101 can be fully detected by the brake pad detection equipment on the rear side. When the longitudinal moving support block 53 moves forward along the longitudinal moving groove 51, the cooperation between the follower gear 63 and the longitudinal rack 62 allows the rotating shaft 56 to rotate clockwise. When the rolling wheel 57 is disengaged from the trapezoidal plate 510, the follower gear 63 and the longitudinal rack 62 cooperate to restore the rotating shaft 56 to its initial state, that is, the brake pad 10 is in a longitudinal state.

[0049] The brake pad unloading rack installation mechanism 3 is installed at the rear side of the left end of the seat plate 1 , and the brake pad unloading rack 4 is installed on the brake pad unloading rack installation mechanism 3 .

[0050] The brake pad unloading rack installation mechanism 3 includes a lifting assembly, a lifting platform 34, a quick-release clamping and locking assembly, a quick-release plate 310 and a positioning column 311. The lifting platform 34 is installed on the rear side of the left end of the seat plate 1 through the lifting assembly. A slot is provided at the front end of the upper side of the lifting platform 34, and a positioning column 311 is provided in the slot. The rear end of the quick-release plate 310 is clamped in the slot, and the positioning hole on the quick-release plate 310 is matched and connected with the positioning column 311. A quick-release clamping and locking assembly is installed on the upper side of the lifting platform 34.

[0051] The lifting assembly includes a column 31, a sleeve 32, and a lifting cylinder 33. Two sleeves 32 are respectively arranged on the left and right sides of the lifting platform 34. The two sleeves 32 are respectively slidably connected to the two columns 31. The bottom ends of the two columns 31 are fixedly connected to the left rear side of the seat plate 1. The bottom of the lifting platform 34 is fixedly connected to the left rear side of the seat plate 1 through the vertical lifting cylinder 33. The column 31 and the sleeve 32 cooperate to allow the lifting platform 34 to move only up and down. The extension and contraction of the lifting cylinder 33 can drive the lifting platform 34 to move up and down.

[0052] The lifting assembly is used to drive the lifting platform 34 to move up and down. When the lifting platform 34 moves up, the brake pad unloading rack 4 is also lifted up with the quick release plate 310. At this time, the brake pad 10 in the brake pad unloading rack 4 will not be supported and taken away by the brake pad unloading supporting mechanism 7, and the device can be controlled to stop unloading. The positioning column 311 is used to stably clamp the quick release plate 310 in the card slot, and the quick release clamping locking assembly is used to quickly install the quick release plate 310 and the lifting platform 34, so as to facilitate the rapid replacement of the quick release plate 310 and the brake pad unloading rack 4.

[0053] The quick-release clamping locking assembly includes a side strip 35, a locking plate 36, a handle 37, a spring support block 38 and a locking spring 39. Two side strips 35 are fixedly connected to the left and right ends of the upper side of the lifting platform 34. Limiting grooves are respectively provided on the two side strips 35. The two ends of the locking plate 36 are respectively connected to the two limiting grooves for longitudinal sliding. A handle 37 is installed on the top of the locking plate 36. The rear side of the locking plate 36 is connected to the spring support block 38 through the locking spring 39. The spring support block 38 is fixed on the lifting platform 34. The front bottom of the locking plate 36 corresponds to the upper side of the rear end of the quick-release plate 310. In a natural state, the locking spring 39 pushes the locking plate 36 to move forward along the limiting groove, and the front bottom of the locking plate 36 covers the upper side of the rear end of the quick release plate 310, so that the quick release plate 310 cannot move up and disengage from the slot, and cooperates with the positioning column 311 to lock the quick release plate 310. When the quick release plate 310 needs to be removed from the slot, the locking plate 36 is pushed backward with the help of the handle 37, and the locking spring 39 is compressed. The front side of the locking plate 36 no longer covers the quick release plate 310. At this time, the quick release plate 310 can be pulled upward to remove the quick release plate 310 from the slot, thereby completing the quick disassembly and assembly of the quick release plate 310 and the lifting platform 34.

[0054] The brake pad unloading rack 4 includes an unloading side plate 41, a connecting rod 42, an unloading guide groove 43, a discharge groove 44 and a placement guide notch 45. The front end of the quick-release plate 310 is fixedly connected to a unloading side plate 41. The unloading side plate 41 is tilted so that it is higher on the left and lower on the right. The top of the unloading side plate 41 is connected to another unloading side plate 41 through two connecting rods 42. The right end of the unloading side plate 41 is located on the upper side of the unloading sprocket 213 that is supported. Unloading guide grooves 43 are respectively provided at the bottom of the side where the two unloading side plates 41 are close to each other. The right end of each unloading guide groove 43 is bent to the upper right to form a discharge groove 44. Placement guide notches 45 are respectively provided at the left ends of the side where the two unloading side plates 41 are close to each other. The bottom of each placement guide notch 45 is respectively connected to the upper side of the left end of the unloading guide groove 43. The unloading side plate 41 and the connecting rod 42 constitute the main body of the brake pad unloading rack. The brake pad 10 is placed between the left ends of the two unloading side plates 41. The two ear seats 103 in the brake pad 10 are respectively located in the two placement guide notches 45. Then the two ear seats 103 slide rightward into the two unloading guide grooves 43 respectively. The brake pad 10 slides to the right end of the two unloading side plates 41 through the ear seats 103. Due to gravity, the brake pad 10 is in a vertical state. The bottom of the steel plate 101 in the brake pad 10 extends to below the bottom of the right end of the two unloading side plates 41. Due to the setting of the discharge trough 44, the brake pad 1 0 will not slide out from the right end of the unloading guide groove 43, avoiding the brake pad 10 from sliding out from the right end of the two unloading side plates 41 uncontrolled due to gravity. When the brake pad 10 is supported by the brake pad unloading supporting mechanism 7 and moves to the upper right, the ear seat 103 on the steel plate 101 moves along the two discharge grooves 44, so that the brake pad 10 can be unloaded from the brake pad unloading rack 4. The setting of the placement guide notch 45 is conducive to the two ear seats 103 on the steel plate 101 to quickly align with the two unloading guide grooves 43, so as to facilitate and quickly place multiple brake pads 10 between the two unloading side plates 41.

[0055] When in use, a plurality of brake pads 10 to be unloaded are placed in the brake pad unloading rack 4. The brake pad 10 comprises a steel plate 101, a friction block 102 and an ear seat 103. The friction block 102 is arranged on the right side of the steel plate 101. The horizontal position of the bottom of the friction block 102 is higher than the bottom of the steel plate 101. Two ear seats 103 are arranged at the front and rear ends of the top of the steel plate 101 respectively. The conveying motor 27 drives the driving shaft 25 to rotate clockwise, and the driving shaft 25 drives the two driving sprockets 26 to rotate clockwise. With the help of the driven shaft 22 and The driven sprocket 23 installs the chain 28, and the rotation of the driving sprocket 26 makes the two chains 28 rotate clockwise. The multiple unloading mounting frames 214 between the two chains 28 also move with the chain 28. The unloading mounting frames 214 can drive the brake pad follower longitudinal movement mechanism 5, the follower steering mechanism 6 for brake pad detection, and the brake pad unloading supporting mechanism 7 to move. When the unloading mounting frames 214, the brake pad follower longitudinal movement mechanism 5, the follower steering mechanism 6 for brake pad detection, and the brake pad unloading supporting mechanism 7 move along the inverted V-shaped portion of the chain 28, the brake pad unloading mounting frames 214, the brake pad follower longitudinal movement mechanism 5, the brake pad detection follower steering mechanism 6, and the brake pad unloading supporting mechanism 7 move along the inverted V-shaped portion of the chain 28. The left side of the brake pad unloading support mechanism 7 gradually moves to the upper right. When the brake pad unloading support mechanism 7 approaches the top of the inverted V-shaped part of the chain 28, the top of the brake pad unloading support mechanism 7 supports the bottom of a brake pad 10 at the rightmost end of the brake pad unloading rack 4. Then the brake pad 10 on the brake pad unloading support mechanism 7 continues to move along the right side of the inverted V-shaped part of the chain 28 to the horizontal part of the chain 28. Then the brake pad follower longitudinal movement mechanism 5 allows the brake pad unloading support mechanism 7 and the brake pad 10 to move backward relative to the chain 28. The brake pad 10 It can be close to the brake pad detection equipment located on the rear side. The follow-up steering mechanism 6 for brake pad detection allows the brake pad unloading supporting mechanism 7 and the brake pad 10 to rotate ninety degrees counterclockwise, allowing the brake pad detection equipment to detect the brake pad 10 from multiple angles. The chain 28 continues to move clockwise, and the brake pad unloading supporting mechanism 7 and the brake pad 10 are gradually reset until the brake pad unloading supporting mechanism 7 and the brake pad 10 move to the rightmost end, and the brake pad 10 falls off from the brake pad unloading supporting mechanism 7, completing the entire detection and unloading process of the brake pad 10.

[0056] For example 2, please refer to Figures 1 to 10 This embodiment provides a technical solution: a brake pad product detection and unloading device. The structure of this embodiment is roughly the same as that of the first embodiment, except that:

[0057] The brake pad defective unloading mechanism 8 is also included. The brake pad defective unloading mechanism 8 includes an unloading platform 81, a movable seat 82, a rotation control component, a telescopic control component, a swing rod 87, an unloading mounting plate 811, a brake pad upper support rod 812, an electromagnet 813 and a defective unloading trough 814. The top of the rectangular bracket 58 is fixedly connected to the unloading platform 81, and the movable seat 82 is fixedly connected to the unloading platform 81. The movable seat 82 is connected to one end of the swing rod 87 through the rotation control component. The other end is connected to a material unloading mounting plate 811 through a telescopic control component, and an electromagnet 813 is installed in the middle circular groove of the material unloading mounting plate 811. Two brake pad upper support rods 812 are fixedly connected to both sides of one end of the material unloading mounting plate 811 away from the chain 28, and a defective material unloading trough body 814 is connected to the front end of the material unloading platform 81. The rotation control component is used to drive the rocker arm 87 to rotate relative to the movable seat 82, and the telescopic control component is used to drive the material unloading mounting plate 811 to move relative to the rocker arm 87.

[0058] The horizontal position of the upper side of the unloading platform 81 is higher than the upper side of the right end of the chain 28 .

[0059] The rotary control assembly includes a control gear 83, a control rack 84, a limit bar 85, and a feeding cylinder 86. The control gear 83 is rotatably connected in the movable seat 82. The control gear 83 is fixedly connected to the end of the rocker arm 87, and the rocker arm 87 is distributed radially along the control gear 83. The bottom of the movable seat 82 is longitudinally slidably connected to the limit bar 85. The top of the limit bar 85 is fixedly connected to the control rack 84. The control rack 84 is meshingly connected to the control gear 83. The front end of the limit bar 85 is fixedly connected to the telescopic end on the rear side of the feeding cylinder 86, and the fixed end on the front side of the feeding cylinder 86 is fixedly installed on the feeding platform 81. The feeding cylinder 86 extends to push the limit bar 85 and the control rack 84 to move backward. The meshing of the control rack 84 and the control gear 83 can drive the rocker arm 87 to swing forward. The feeding cylinder 86 shortens to pull the limit bar 85 and the control rack 84 forward, which can drive the rocker arm 87 to swing backward.

[0060] The telescopic control assembly includes a telescopic guide groove 88, a telescopic sleeve 89, and an electric telescopic rod 810. A telescopic guide groove 88 is provided at one end of the rocker arm 87 away from the control gear 83. A telescopic sleeve 89 is slidably connected in the telescopic guide groove 88. One end of the telescopic sleeve 89 away from the rocker arm 87 is fixedly connected to a blanking mounting plate 811. The inner side of the telescopic guide groove 88 is connected to the inner side of the telescopic sleeve 89 through the electric telescopic rod 810. The extension of the electric telescopic rod 810 can drive the telescopic sleeve 89 to extend out of the telescopic guide groove 88, and the shortening of the electric telescopic rod 810 can drive the telescopic sleeve 89 to retract into the telescopic guide groove 88.

[0061] When the brake pad detection device detects that the brake pad 10 is defective, the conveying motor 27 stops working. At this time, the friction block 102 in the brake pad 10 detected as defective faces the rear side, and the rotary control component drives the swing rod 87 to swing backward until the swing rod 87 is in a horizontal state. Then the telescopic control component drives the blanking mounting plate 811 to move backward relative to the swing rod 87. The rear side of the blanking mounting plate 811 is close to the front side of the steel plate 101 in the brake pad 10, and the two brake pad upper support rods 812 are at the bottom of the two ear seats 103 on the steel plate 101. The electromagnet 813 works to magnetically attract the steel plate 101, and the steel plate 101 is close to the rear side of the blanking mounting plate 811. Then the control assembly is rotated to drive the swing rod 87 to swing forward. The two brake pad upper support rods 812 lift up the two ear seats 103 to allow the steel plate 101 to separate from the magnetic block 73 in the arc bracket 72. The swing rod 87 continues to swing forward until the swing rod 87 is in a horizontal state. The electromagnet 813 stops working, and the brake pad 10 falls downward due to gravity and falls onto the defective blanking chute 814, completing the blanking of the defective brake pad 10.

[0062] For example 3, please refer to Figures 1 to 10 This embodiment provides a technical solution: a brake pad product detection and unloading device. The structure of this embodiment is roughly the same as that of the second embodiment, except that:

[0063] It also includes a brake pad orderly collection mechanism 9, which includes a collection box tilted limit bracket, a brake pad collection box 94, an ear seat limit collection groove 95 and a brake pad collection support rod 96. A collection box tilted limit bracket is installed at the right end of the seat plate 1, and a brake pad collection box 94 tilted with the left higher and the right lower is placed on the collection box tilted limit bracket.

The brake pad collection box 94 is placed on the upper side of the inclined plate 92, and the brake pad collection box 94 is located on the inner side of the limit U-shaped frame 93. The limit U-shaped frame 93 limits the brake pad collection box 94, so that the brake pad collection box 94 is accurately placed, ensuring that with the operation of the unloading conveying mechanism 2, the two brake pad collection support rods 96 can just hold the two ear seats 103 on the front and rear sides of the steel plate 101 at the rightmost end of the unloading conveying mechanism 2, so that the brake pad 10 can be smoothly separated from the arc bracket 72.

[0065] After the inspection, the brake pad 10 that has no problems continues to move to the right along with the chain 28 and the unloading mounting frame 214. When the brake pad 10 moves to the rightmost end, the two brake pad collecting support rods 96 support the bottom of the two ear seats 103 on the front and rear sides of the steel plate 101, so that the steel plate 101 in the brake pad 10 is separated from the magnetic block 73 in the arc bracket 72, and the two ear seats 103 on the front and rear sides of the steel plate 101 slide to the lower right along the ear seat limit collecting groove 95 in the brake pad collecting box 94, and finally the brake pad 10 is collected into the brake pad collecting box 94. After the brake pad collecting box 94 is full, the brake pad collecting box 94 on the collection box tilt limit bracket can be replaced.
