Description

Technical Field

[0001] This invention belongs to the field of sheet metal slitting technology, and in particular relates to a slitting device and a slitting machine. Background Technology

[0002] To improve space utilization, boards are usually stored in a stacked manner. When it is necessary to take out the boards one by one, a robotic arm with adsorption function can be used to pick them up and separate them.

[0003] However, in some situations, using a robotic arm to grip the board is more reliable than adsorption. For example, in the PCB industry, coated boards are made by stacking a thin aluminum plate on top, a paper backing board on the bottom, and a PCB board in the middle. Then, pins and tape are used to fix the three layers of boards together. The boards are stacked back to back in a cross-stack manner.

[0004] The paper backing board for the coated sheet can be reused. Sometimes, the paper backing board is made from recycled material from the previous batch of coated sheets after drilling. Therefore, when using the adsorption method to separate the sheets, if the adsorption is applied to one side of the thin aluminum sheet, the thin aluminum sheet is prone to deformation, leading to vacuum breakage and sheet drop. If the adsorption is applied to the side with the paper backing board, the holes left from drilling will cause vacuum breakage and sheet drop. Moreover, regardless of which side is applied, the tape may not be able to withstand the weight, leading to damage and breakage, making the coated sheet prone to defects during processing.

[0040] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0041] like Figures 1 to 7 As shown, in one aspect, an embodiment of the present invention provides a board separation device. In the PCB industry, the board separation device is used to separate the upper and lower layers of the coated board. The coated board is stacked in pairs. A robotic arm places the two pairs of coated boards on the board separation device, which can separate the upper and lower coated boards.

[0042] The separating device includes a base frame 1, a lifting mechanism 2, and a brushing mechanism 3. The lifting mechanism 2 includes a clamping assembly 21 and a lifting drive 22. The lifting drive 22 is mounted on the base frame 1, and the clamping assembly 21 is mounted on the output end of the lifting drive 22. The clamping assembly 21 is used to clamp one end of the upper layer of rubber-coated board. The lifting drive 22 can drive the clamping assembly 21 to move, thereby lifting one end of the upper layer of rubber-coated board clamped by the clamping assembly 21, so that the upper layer of rubber-coated board and the lower layer of rubber-coated board are no longer stacked.

[0043] The brush plate mechanism 3 includes a brush plate drive 31, a brush plate assembly 32, and a moving assembly 33. The brush plate assembly 32 is connected to the brush plate drive 31. The brush plate drive 31 can drive the brush plate assembly 32 to move up and down. While the lifting drive 22 is in motion, the brush plate assembly 32 is inserted between the upper and lower rubber-coated plates under the drive of the brush plate drive 31. The brush plate assembly 32 abuts against the upper rubber-coated plate. The moving assembly 33 can drive the brush plate assembly 32 to move away from the lifting mechanism 2. The brush plate assembly 32 moves along the surface of the upper rubber-coated plate towards the lower rubber-coated plate to support the upper rubber-coated plate, so that the upper rubber-coated plate gradually separates from the lower rubber-coated plate. The upper rubber-coated plate is supported by the clamping assembly 21 and the brush plate assembly 32.

[0044] The separating device provided in this embodiment of the invention separates double-layer coated boards. The clamping assembly 21 clamps one end of the upper coated board, while the lifting drive 22 lifts the upper coated board. The brush drive 31 then lifts the brush assembly 32 and places it in the gap between the upper and lower boards. At this point, the moving assembly 33 moves, causing the brush assembly 32 to move, thus separating the upper and lower coated boards by a distance. This facilitates the insertion and gripping of the upper coated board by a robotic arm, avoiding the problem of vacuum breakage and board drop when using a suction cup to adsorb the upper coated board, reducing damage to the coated board, and minimizing defects.

[0045] In one embodiment, such as Figure 1 As shown, the base frame 1 is connected to multiple fixed feet 18, which provide support for the base frame 1.

[0046] In one embodiment, such as Figure 5 As shown, the brush assembly 32 includes a brush shaft 321 and multiple brush wheels 322 disposed on the brush shaft 321. The multiple brush wheels 322 are spaced apart. The brush drive 31 includes a first brush cylinder 311 and a second brush cylinder 312. The two ends of the brush shaft 321 are respectively connected to the output ends of the first brush cylinder 311 and the second brush cylinder 312. Preferably, the two ends of the brush shaft 321 are respectively connected to a first brush shaft fixing plate 323 and a second brush shaft fixing plate 324. The first brush shaft fixing plate 323 is connected to the output end of the first brush cylinder 311, and the second brush shaft fixing plate 324 is connected to the output end of the second brush cylinder 312. The first brush cylinder 311 and the second brush cylinder 312 act simultaneously to push the brush shaft 321 to move up and down. The brush wheels 322 follow the movement of the brush shaft 321 and can abut against and support the upper coated board.

[0047] Along the axial direction of the brush shaft 321, each brush wheel 322 is provided with a stop ring on both sides. The stop ring limits the position of the brush wheel 322. The brush wheel 322 can rotate around the brush shaft 321. The brush wheel 322 and the upper rubber sheet are subjected to rolling friction, which can prevent the brush wheel 322 from scratching the upper rubber sheet.

[0048] In some preferred embodiments, four brush rollers 322 are provided, arranged in pairs, with one pair located near one edge of the upper rubber-coated plate and the other pair located near the other edge of the upper rubber-coated plate.

[0049] In one embodiment, such as Figure 4 , Figure 5As shown, the moving component 33 includes a first motor 331, a first synchronization component 332, and a second synchronization component 333. The first motor 331 is mounted on the base frame 1. The output end of the first motor 331 is connected to one end of the first synchronization component 332 and one end of the second synchronization component 333. The other ends of the first synchronization component 332 and the second synchronization component 333 are connected to the base frame 1. A first brush plate cylinder 311 is connected to the first synchronization component 332, and a second brush plate cylinder 312 is connected to the second synchronization component 333. The first synchronization component 332 drives the first brush plate cylinder 311 to move under the drive of the first motor 331, and the second synchronization component 333 drives the second brush plate cylinder 312 to move under the drive of the first motor 331. The first motor 331 can drive the first synchronization component 332 and the second synchronization component 333 to move simultaneously, thereby driving the first brush plate cylinder 311 and the second brush plate cylinder 312 to move, and thus driving the brush plate shaft 321 to move.

[0050] like Figure 4 , Figure 5 As shown, the first synchronization component 332 and the second synchronization component 333 are respectively disposed on both sides of the base frame 1. The first motor 331 is connected to the first synchronization component 332 and the second synchronization component 333 respectively through the first transmission component 34. The first transmission component 34 includes a first transmission drive pulley 341, a first transmission driven pulley 342, a first transmission synchronous belt 343, and a first drive shaft 344. The first transmission drive pulley 341 is connected to the output end of the first motor 331, the first transmission driven pulley 342 is mounted on the first drive shaft 344, and the first transmission synchronous belt 343... The first drive wheel 341 and the first driven wheel 342 are arranged around each other. The first motor 331 drives the first drive wheel 341 to rotate, which in turn drives the first driven wheel 342 to rotate via the first synchronous belt 343. This drives the first drive shaft 344 to rotate. The first drive shaft 344 is connected between the first synchronous component 332 and the second synchronous component 333 to achieve synchronous movement of the first synchronous component 332 and the second synchronous component 333. This, in turn, drives the first brush plate cylinder 311, the second brush plate cylinder 312 and the brush plate assembly 32 to move.

[0051] In one embodiment, such as Figure 5As shown, the first synchronization component 332 includes a first driving pulley 3321, a first driven pulley 3322, and a first synchronization belt 3323. The first synchronization belt 3323 is arranged around the first driving pulley 3321 and the first driven pulley 3322. The second synchronization component 333 includes a second driving pulley 3331, a second driven pulley 3332, and a second synchronization belt 3333. The second synchronization belt 3333 is arranged around the second driving pulley 3331 and the second driven pulley 3332. The first driving pulley 3321 and the second driving pulley 3331 are connected to the two ends of the first drive shaft 344. The output end of the first motor 331 is connected to the first driving pulley 3321 and the second driving pulley 3331 through the first transmission component 34. The first driven pulley 3322 and the second driven pulley 3332 are connected to the base frame 1. The first motor 331 can drive the first drive shaft 344 to rotate, and the first drive shaft 344 drives the first drive wheel 3321 and the second drive wheel 3331 to rotate, thereby causing the first synchronous belt 3323 and the second synchronous belt 3333 to drive each other. The first brush plate cylinder 311 is connected to the first synchronous belt 3323, and the second brush plate cylinder 312 is connected to the second synchronous belt 3333. The first synchronous belt 3323 can drive the first brush plate cylinder 311 to move, and the second synchronous belt 3333 can drive the second brush plate cylinder 312 to move. The brush plate shaft 321 connected between the first brush plate cylinder 311 and the second brush plate cylinder 312 will move accordingly, thereby realizing the driving of the brush plate assembly 32 by the moving component 33.

[0052] In one embodiment, such as Figure 4 , Figure 5 As shown, the moving component 33 also includes a first guide 334 and a second guide 335. The first guide 334 and the second guide 335 are mounted on the base frame 1. The first guide 334 is used to guide the first brush cylinder 311, and the second guide 335 is used to guide the second brush cylinder 312.

[0053] In one embodiment, such as Figure 5 , Figure 6 As shown, the first brush plate cylinder 311 is mounted on the first mounting base 336, which is slidably connected to the first guide member 334. The first mounting base 336 is connected to the first synchronization assembly 332. The first mounting base 336 has a first vertical plate and a first horizontal plate. The first brush plate cylinder 311 is mounted on the first vertical plate. The first guide member 334 can be a first guide rod, with a first bearing sleeved on the outer side of the first guide rod. The first bearing is mounted on the first mounting base 336, and the first guide rod provides support for the first brush plate cylinder 311. The first horizontal plate extends toward the first synchronization assembly 332 and is connected to the first synchronous belt 3323 via a synchronous belt clamping plate. The first synchronous belt 3323 drives the first horizontal plate to move, thereby causing the first mounting base 336 to move axially along the first guide rod.

[0054] The second brush plate cylinder 312 is mounted on the second mounting base 337, which is slidably connected to the second guide member 335. The second mounting base 337 is connected to the second synchronization assembly 333. The second mounting base 337 has a second vertical plate and a second horizontal plate. The second brush plate cylinder 312 is mounted on the second vertical plate. The second guide member 335 can be a second guide rod, with a second bearing sleeved on the outer side of the second guide rod. The second bearing is mounted on the second mounting base 337, and the second guide rod supports the second brush plate cylinder 312. The second horizontal plate extends towards the second synchronization assembly 333 and is connected to the second synchronous belt 3333 via a synchronous belt clamping plate. The second synchronous belt 3333 drives the second horizontal plate to move, thereby causing the second mounting base 337 to move axially along the second guide rod. The first motor 331 drives the first synchronous belt 3323 and the second synchronous belt 3333 to move synchronously via the first drive shaft 344, thereby causing the first mounting base 336 and the second mounting base 337 to move synchronously.

[0055] In some alternative embodiments, the first guide 334 may be a linear guide rail, and the second guide 335 may be a linear guide rail.

[0056] In one embodiment, such as Figure 4 , Figure 5 As shown, the base frame 1 is equipped with a first driving wheel seat 11, a first driven wheel seat 12, a second driving wheel seat 13, and a second driven wheel seat 14. A first guide member 334 connects the first driving wheel seat 11 and the first driven wheel seat 12. The first guide member 334 is a first guide rod, with its two ends connected to the first driving wheel seat 11 and the first driven wheel seat 12, respectively. A second guide member 335 connects the second driving wheel seat 13 and the second driven wheel seat 14. The second guide member 335 is a second guide rod, with its two ends connected to the second driving wheel seat 13 and the second driven wheel seat 14, respectively.

[0057] The first driving wheel 3321 is mounted on the first driving wheel seat 11, the first driven wheel 3322 is mounted on the first driven wheel seat 12, the second driving wheel 3331 is mounted on the second driving wheel seat 13, and the second driven wheel 3332 is mounted on the second driven wheel seat 14.

[0058] like Figure 5As shown, the first drive wheel seat 11 is provided with a first clearance groove 111, and the first drive wheel 3321 is disposed in the first clearance groove 111. The second drive wheel seat 13 is provided with a second clearance groove 131, and the second drive wheel 3331 is disposed in the second clearance groove 131. One end of the first drive shaft 344 is inserted into the first clearance groove 111 and connected to the first drive wheel 3321, and the other end of the first drive shaft 344 is inserted into the second clearance groove 131 and connected to the second drive wheel 3331.

[0059] The first driven wheel seat 12 is provided with a third clearance groove 121, and the first driven wheel 3322 is connected to the third clearance groove 121 through a bearing. The second driven wheel seat 14 is provided with a fourth clearance groove 141, and the second driven wheel 3332 is connected to the fourth clearance groove 141 through a bearing.

[0060] In one embodiment, such as Figure 4 As shown, a first sensor 151 and a second sensor 152 are provided on the base frame 1, and a sensor sensing plate 153 is connected to the first mounting base 336. When the first synchronization component 332 and the second synchronization component 333 drive the brush plate assembly 32 to move, the sensor sensing plate 153 and the first sensor 151 cooperate to limit the starting position of the first mounting base 336, and the sensor sensing plate 153 and the second sensor 152 cooperate to limit the maximum stroke of the first mounting base 336. The stroke of the first brush plate mounting base should not exceed the range limited by the first sensor 151 and the second sensor 152.

[0061] Preferably, such as Figure 5 As shown, a first buffer screw 112 is threaded onto the first driving wheel seat 11, and a second buffer screw 122 is threaded onto the first driven wheel seat 12. When the first mounting seat 336 exceeds its maximum stroke, interference may occur between the brush plate mechanism 3 and the lifting mechanism 2, potentially damaging the first chuck 2131 and the second chuck 2141. The first buffer screw 112 and the second buffer screw 122 limit the extreme stroke of the first mounting seat 336. The first buffer screw 112 and the second buffer screw 122 also have a foolproof function, preventing the first mounting seat 336 from colliding with the first driving wheel seat 11 and the first driven wheel seat 12, and preventing interference between the brush plate mechanism 3 and the lifting mechanism 2. The buffer position can be adjusted by turning the first buffer screw 112 and the second buffer screw 122.

[0062] A third buffer screw 132 is threaded onto the second drive wheel seat 13, and a fourth buffer screw 142 is threaded onto the second driven wheel seat 14. When the second mounting seat 337 exceeds its maximum stroke, the third buffer screw 132 and the fourth buffer screw 142 can limit the limit stroke of the second mounting seat 337. The third buffer screw 132 and the fourth buffer screw 142 have a foolproof function to prevent the second mounting seat 337 from colliding with the second drive wheel seat 13 and the second driven wheel seat 14.

[0063] In one embodiment, such as Figure 2 , Figure 3 As shown, the clamping assembly 21 includes a clamping cylinder 211, a clamping cylinder mounting plate 212, an upper clamping plate 213, and a lower clamping plate 214. The clamping cylinder 211 is mounted on the clamping cylinder mounting plate 212, which is connected to the output end of the lifting drive member 22. The lower clamping plate 214 is mounted on the clamping cylinder mounting plate 212 and is positioned below the clamping cylinder 211 along the length of the clamping cylinder mounting plate 212. The upper clamping plate 213 is connected to the output end of the clamping cylinder 211, and the clamping cylinder 211 can drive the upper clamping plate 213 to move towards the lower clamping plate 214. When the double-layered rubber-coated sheets are placed crosswise, the upper and lower rubber-coated sheets do not completely overlap. When the sheet material is conveyed to the clamping assembly 21, one end of the upper rubber-coated sheet extends between the upper pressure plate 213 and the lower pressure plate 214. The clamping cylinder 211 drives the upper pressure plate 213 downward, and the upper pressure plate 213 and the lower pressure plate 214 together clamp the upper rubber-coated sheet. The lifting drive 22 is activated, which can drive the clamping assembly 21 to move upward as a whole, thereby lifting one end of the upper rubber-coated sheet upward. The upper and lower rubber-coated sheets are partially separated. The moving assembly 33 drives the brush assembly 32 to move, realizing the complete separation between the upper and lower rubber-coated sheets.

[0064] In one embodiment, such as Figure 2 , Figure 3 As shown, the upper clamping plate 213 is provided with a plurality of first clamps 2131, which are spaced apart along the length of the upper clamping plate 213. The lower clamping plate 214 is provided with a plurality of second clamps 2141, which are spaced apart along the length of the lower clamping plate 214. The first clamps 2131 and the second clamps 2141 are provided in a one-to-one correspondence. The first clamps 2131 and the second clamps 2141 are used to clamp the upper rubber-coated plate. The first clamps 2131 and the second clamps 2141 are made of soft material, which can avoid excessive deformation caused by the rubber-coated plate being lifted on one side, thus preventing defects.

[0065] In one embodiment, such as Figure 3As shown, a first through-beam sensor 2132 is provided on the upper clamping plate 213, and a second through-beam sensor 2142 is provided on the lower clamping plate 214. One of the first through-beam sensor 2132 and the second through-beam sensor 2142 is a transmitter, and the other is a receiver. When the end of the upper rubber-coated plate enters between the first through-beam sensor 2132 and the second through-beam sensor 2142, the light emitted by the transmitter is cut off. The through-beam sensor detects that the upper rubber-coated plate has been in place, and the clamping cylinder 211 starts to operate, so that the upper clamping plate 213 and the lower clamping plate 214 clamp the upper rubber-coated plate together.

[0066] In one embodiment, such as Figure 4 , Figure 7 As shown, the plate separating device also includes a translation mechanism 4 mounted on the base frame 1. The translation mechanism 4 includes a second motor 41, a third synchronization component 42, and a fourth synchronization component 43. The output end of the second motor 41 is connected to the third synchronization component 42 and the fourth synchronization component 43. The double-layer rubber-coated plate is placed on the third synchronization component 42 and the fourth synchronization component 43. The third synchronization component 42 and the fourth synchronization component 43 are used to support the rubber-coated plate and transport the rubber-coated plate under the drive of the second motor 41. The rubber-coated plate is transported to the clamping component 21.

[0067] like Figure 4 , Figure 7 As shown, the second motor 41 is connected to the third synchronization component 42 and the fourth synchronization component 43 respectively through the second transmission component 44. The second transmission component 44 includes a second transmission drive wheel 441, a second transmission driven wheel 442, a second transmission timing belt 443, and a second drive shaft 444. The second transmission drive wheel 441 is connected to the output end of the second motor 41. The second transmission driven wheel 442 is mounted on the second drive shaft 444. The second transmission timing belt 443 is arranged around the second transmission drive wheel 441 and the second transmission driven wheel 442. When the second motor 41 moves, it drives the second transmission drive wheel 441 to rotate, which in turn drives the second transmission driven wheel 442 to rotate through the second transmission timing belt 443, thereby driving the second drive shaft 444 to rotate. The second drive shaft 444 is connected between the third synchronization component 42 and the fourth synchronization component 43, realizing the synchronous movement of the third timing belt 423 and the fourth timing belt 433, thereby realizing the conveying of the rubber sheet.

[0068] The power source for the translation mechanism 4 is not limited to the second motor; it can also be a cylinder. However, since the size range of different sheet metal specifications is relatively large, the moving distance will change in order to ensure that the center of different sheet metal specifications remains unchanged when placed in the translation mechanism 4. Therefore, in order to meet the needs of different sheet metal specifications, a motor is used as the power source, and a synchronous belt is used for transmission. The motor controls the moving distance more accurately and will not fail to stop stably when in position, which would cause damage to the front end of the rubber-coated sheet and affect the subsequent processing accuracy.

[0069] In one embodiment, such as Figure 1 , Figure 4 As shown, a material inlet sensor 17 is installed on the base frame 1. The material inlet sensor 17 is used to detect whether the translation mechanism 4 is supporting a rubber-coated plate. When the material inlet sensor 17 detects that there is material, the second motor 41 is activated, driving the third synchronous belt 423 and the fourth synchronous belt 433 to convey the plate material.

[0070] In one embodiment, such as Figure 2 As shown, the base frame 1 is provided with multiple baffles 16. The baffles 16 are located on the side of the base frame 1 near the lifting mechanism 2. The front ends of the upper and lower rubber-coated plates are not the same. In order to prevent the lower rubber-coated plate from entering the activity range of the brushing mechanism 3 when the double-layer rubber-coated plates move as a whole, thereby affecting the operation of the brushing assembly 32 and the moving assembly 33, the baffles 16 on the base frame 1 can block the lower rubber-coated plate and prevent the lower rubber-coated plate from affecting the brushing action.

[0071] In one embodiment, such as Figure 7 As shown, the third synchronization component 42 includes a third driving pulley 421, a third driven pulley 422, and a third synchronization belt 423. The third synchronization belt 423 is arranged around the third driving pulley 421 and the third driven pulley 422. The fourth synchronization component 43 includes a fourth driving pulley 431, a fourth driven pulley 432, and a fourth synchronization belt 433. The fourth synchronization belt 433 is arranged around the fourth driving pulley 431 and the fourth driven pulley 432. The third driving pulley 421, the third driven pulley 422, the fourth driving pulley 431, and the fourth driven pulley 432 are connected to the base frame 1 through bearing seats. The two ends of the second drive shaft 444 are respectively connected to the third driving pulley 421 and the fourth driving pulley 431. The output end of the second motor 41 is connected to the third driving pulley 421 and the fourth driving pulley 431 through the second transmission component 44. The second motor 41 can drive the second drive shaft 444 to rotate, and the second drive shaft 444 drives the third drive wheel 421 and the fourth drive wheel 431 to rotate, thereby causing the third synchronous belt 423 and the fourth synchronous belt 433 to drive the transmission. The rubber plate is placed on the third synchronous belt 423 and the fourth synchronous belt 433, and the third synchronous belt 423 and the fourth synchronous belt 433 can drive the rubber plate to move.

[0072] In one embodiment, such as Figure 4 , Figure 7As shown, in order to support the third synchronous belt 423 and the fourth synchronous belt 433, the translation mechanism 4 also includes a first receiving member 45 and a second receiving member 46. The section of the third synchronous belt 423 located above the third driving pulley 421 and the third driven pulley 422 abuts against the first receiving member 45. The first supporting member has a supporting function to prevent the rubber sheet from crushing the third synchronous belt 423. The first receiving member 45 has a first limiting cavity. The section of the third synchronous belt 423 located below the third driving pulley 421 and the third driven pulley 422 passes through the first limiting cavity, so that the section of the third synchronous belt 423 is limited in the first limiting cavity, which can prevent the third synchronous belt 423 from tilting and detaching from the third driving pulley 421 and the third driven pulley 422.

[0073] The section of the fourth synchronous belt 433 located above the fourth driving pulley 431 and the fourth driven pulley 432 abuts against the second receiving member 46. The second supporting member has a supporting function to prevent the rubber-coated plate from pressing the fourth synchronous belt 433. The second receiving member 46 has a second limiting cavity. The section of the fourth synchronous belt 433 located below the fourth driving pulley 431 and the fourth driven pulley 432 passes through the second limiting cavity, so that the section of the fourth synchronous belt 433 is limited in the second limiting cavity, which can prevent the fourth synchronous belt 433 from tilting and detaching from the fourth driving pulley 431 and the fourth driven pulley 432.

[0074] In one embodiment, such as Figure 7 As shown, the first receiving component 45 includes a first receiving plate 451, a first connecting plate 452, and a second connecting plate 453. The first receiving plate 451 is connected to the first connecting plate 452 on both sides. The first receiving plate 451 and the first connecting plates 452 on both sides enclose a first limiting cavity. The cross-sectional shape of the first limiting cavity is U-shaped. The lower half of the third synchronous belt 423 is disposed in the first limiting cavity. The second connecting plate 453 is connected to the first connecting plate 452. The second connecting plates 453 on both sides are mounted on the base frame 1. The second connecting plate 453 and the first connecting plate 452 are not flush. The upper half of the third synchronous belt 423 is attached to the first receiving plate 451.

[0075] The second receiving component 46 includes a second receiving plate 461, a third connecting plate 462, and a fourth connecting plate 463. The second receiving plate 461 is connected to the third connecting plate 462 on both sides. The second receiving plate 461 and the third connecting plates 462 on both sides enclose a second limiting cavity. The cross-sectional shape of the second limiting cavity is U-shaped. The lower half of the fourth synchronous belt 433 is disposed in the second limiting cavity. The fourth connecting plate 463 is connected to the third connecting plate 462. The fourth connecting plates 463 on both sides are mounted on the base frame 1. The fourth connecting plate 463 and the third connecting plate 462 are not flush. The upper half of the fourth synchronous belt 433 is attached to the second receiving plate 461.
