The laminating machine of this embodiment includes a material strip feeding device 100, a feeding device 200, a loading device 300, a pressing device 400, a pallet 500, a material strip pushing device 600, a cutting device 700, a receiving device 800 and a frame 900. The pallet 500 is locked and fixed on the frame 900. The pallet 500 is in a long strip shape, and the length direction of the pallet 500 is arranged along the left and right direction. The feeding device 200, the loading device 300, the pressing device 400, the material strip pushing device 600, the cutting device 700 and the receiving device 800 are arranged on the pallet 500 from right to left in sequence, and the material strip feeding device 100 is arranged on the rightmost side of the pallet 500.

[0048] The material strip feeding device 100 is used to provide a material strip with double-sided adhesive tape, wherein the double-sided adhesive tape is attached to the upper side of the material strip. Fig.13 ), the feeding device 200 prepares the injection molded parts 250 in batches, so that the loading device 300 can transfer the injection molded parts 250 to the material belt. The pressing device 400 is used to press the injection molded parts 250 on the double-sided adhesive tape to ensure that the injection molded parts 250 and the material belt are stably bonded. The material belt pushing device 600 is used to drag the material belt on the pallet 500 from right to left. The cutting device 700 is used to cut the material belt, thereby cutting the injection molded parts 250 into pieces. The collecting device 800 is used to collect the cut material belts and stack them together.

[0049] The material tape feeding device 100 includes a material tray 110, a first motor 120, a winding roller 130 and a transition roller 140. The material tray 110 is wound with a material tape whose protective film has not been torn off. The winding roller 130 is connected to the rotating shaft of the first motor 120. Driven by the first motor 120, the winding roller 130 rotates, and the protective film on one side of the material tape is gradually wound around the winding roller 130, thereby actively removing the protective film on one side of the material tape to expose the double-sided tape. Under the guidance of the transition roller 140, the material tape enters the pallet 500.

[0050] Reference Figures 2 to 6 , Figure 2 yes Figure 1 Axonometric view of the feeding device 200, Figure 3 yes Figure 1 Axonometric view of the middle track device 210 and the material blocking device 220, Figure 4 yes Figure 1 An exploded view of the middle track device 210 and the material blocking device 220, Figure 5 yes Figure 1 A top view of the middle stock plate 271, Figure 6 yes Figure 1Left view of the material preparation plate 271. The feeding device 200 of this embodiment includes a track device 210, a material blocking device 220, an auxiliary device 230 and a material moving device 240, the frame 900 includes a bottom plate 910 and a support plate 920, the track device 210 includes a feed plate 211 and a material preparation plate assembly 212, the feed plate 211 is arranged on the right side of the material preparation plate assembly 212, the feed plate 211 is connected to the bottom plate 910 through a direct vibration feeder, and the feed plate 211 is locked and fixed to the bottom plate 910 through two support plates 920.

[0051] A feed trough 261 is provided on the feed plate 211, and the preparation plate assembly 212 includes a preparation plate 271 and a stopper 272. The stopper 272 is locked and fixed on the left end of the preparation plate 271. A preparation trough 265 is provided on the preparation plate 271. The left end of the feed trough 261 is its feed end, the right end of the feed trough 261 is its discharge end, and the left end of the preparation trough 265 is its feed end. The discharge end of the feed trough 261 is connected with the feed end of the preparation trough 265. Therefore, after the injection molded part 250 enters from the feed end of the feed trough 261, it enters into the preparation trough 265 through the discharge end of the feed trough 261. After the injection molded part 250 enters into the preparation trough 265, it can be blocked by the stopper 272 at the right end of the feed trough 261. The stopper 272 can play a role in positioning the injection molded part 250.

[0052] Reference Figures 3 to 9 , Figure 7 yes Figure 1 A front view of the middle stop block 224, Figure 7 yes Figure 1 A top view of the middle stop block 224, Figure 8 yes Figure 1 Bottom view of the middle stopper 224. The feed end of the feed trough 261 is generally connected to the vibration plate, and the injection molded parts 250 arranged by the vibration plate are arranged one by one in the feed trough 261. In order to prevent the injection molded parts 250 from directly entering the preparation trough 265 and affecting the feeding and bonding of the injection molded parts 250, a stopper device 220 is provided. The stopper device 220 includes a photoelectric sensor, a pressure plate 222, a first elastic element, a stopper block 224 and a first mounting plate 225. The first mounting plate 225 is locked and fixed on the upper surface of the preparation plate 271. A first limit hole 263 that is transparent from top to bottom is opened in the first mounting plate 225. The stopper block 224 includes a first limit step 273 and a protrusion 274 (refer to Figure 7 ), the first limiting step 273 and the protrusion 274 are integrally arranged, the protrusion 274 is placed in the first limiting hole 263, the first limiting step 273 can be abutted against the first mounting plate 225, thereby, the blocking block 224 can slide in the up and down directions relative to the first mounting plate 225, and the first limiting step 273 can limit the length of the protrusion 274 extending from the first limiting hole 263.

[0053] The lower end of the protrusion 274 is provided with a slope 266, and the slope 266 is arranged toward the discharge end of the feed trough 261. After the protrusion 274 extends out from the first limiting hole 263, the slope 266 can abut against the injection molded part 250 entering the material preparation trough 265. As a result, the injection molded part 250 can slide along the slope 266 under the action of external force, lift the blocking block 224 upward, and then continue to slide along the material preparation trough 265 and move to the upper material position of the material preparation trough 265.

[0054] In order to enable the blocking block 224 to move downward again after being lifted upward, and to block the next injection molded part 250 through the inclined surface 266, so as to realize the orderly and rhythmic feeding of the injection molded part 250, a first elastic element is provided. The first elastic element gives the blocking block 224 an elastic force close to the bottom surface of the material preparation groove 265, thereby, under the action of the first elastic element, the blocking block 224 can move downward again after retracting upward.

[0055] In this embodiment, the first elastic element is a first compression spring 223, and a positioning hole 268 is opened on the stop block 224. The first compression spring 223 is placed in the positioning hole 268. The upper surface of the first mounting plate 225 is locked and fixed with a pressure plate 222. The upper end of the first compression spring 223 is abutted against the lower surface of the pressure plate 222. When the first compression spring 223 is installed in the positioning hole 268, the pressure plate 222 makes the first compression spring 223 in a predetermined compression state, thereby the stop block 224 is subjected to a downward elastic force.

[0056] In another embodiment, the first elastic element can use a corrugated tube installed in the same manner as the first compression spring 223, or a tension spring. When the tension spring is used, the two ends of the tension spring are respectively fixedly connected to the stop block 224 and the first mounting plate 225. When the stop block 224 moves upward, the tension spring is stretched, thereby also giving the first mounting plate 225 a restoring elastic force.

[0057] In order to count the feeding quantity of the material preparation slot 265, a first photoelectric sensor is provided. In the present embodiment, the first photoelectric sensor is selected as a reflective photoelectric sensor 221. In order to install the reflective photoelectric sensor 221 and ensure the normal operation of the reflective photoelectric sensor 221, a mounting hole 262 which is transparent from top to bottom is opened on the pressure plate 222, and a through hole 267 is opened on the material blocking block 224. The mounting hole 262 is aligned with the through hole 267. The reflective photoelectric sensor 221 is placed in the mounting hole 262 and is locked in the mounting hole 262 by a set screw. The light emitted by the reflective photoelectric sensor 221 passes through the through hole 267 and is emitted to the bottom surface of the material preparation slot 265. When an injection molded part 250 passes through the material preparation slot 265, the travel of the reflected light received by the reflective photoelectric sensor 221 changes, thereby detecting whether an injection molded part 250 passes through the material preparation slot 265. After using a counter, the feeding quantity of the material preparation slot 265 can be counted.

A push rod 297 is arranged at the upper end of the material moving rod 243. Thus, under the action of the lifting device 241, the material moving rod 243 located below the material preparation plate 271 moves upward, and the push rod 297 at the upper end of the material moving rod 243 passes through the avoidance hole 264 and enters into the material preparation groove 265. Under the action of the translation device 242, the material moving rod 243 moves in the left and right directions, and the push rod 297 pushes the injection molded part 250 to slide along the material preparation groove 265.

The second slider is locked and fixed on the lower surface of the push plate 292, and the second slide rail is locked and fixed on the upper surface of the base plate 283. The length direction of the second slide rail is set along the left and right direction. Under the constraint of the second sliding component 294, the push plate 292 can only move along the left and right direction.

[0063] In order to limit the extreme position of the push plate 292 moving to the left, a buffer plate 295 and a hydraulic buffer 296 are provided. The buffer plate 295 is locked and fixed on the left end of the base plate 283, and the hydraulic buffer 296 is locked and fixed on the buffer plate 295. Through the buffering of the hydraulic buffer 296, the extreme position of the push plate 292 moving to the left can be determined.

[0064] In other embodiments, the lifting device 241 and the translation device 242 can be replaced by a combination of a motor and a lead screw nut.

[0065] Reference Figure 2 , Figure 5 and Figure 6 In order to prevent the injection molded part 250 from jumping out of the material preparation groove 265 when the push rod 297 pushes the injection molded part 250 to move along the material preparation groove 265, an auxiliary device 230 is provided.

The cover 231 is locked and fixed to the push rod of the first cylinder 232. Under the action of the first cylinder 232, the cover plate 231 can move in the left and right directions. After the push rod 297 passes through the avoidance hole 264, it is held against the injection molded part 250, and when the push rod 297 pushes the injection molded part 250 to move along the material preparation groove 265, the cover plate 231 is above the material preparation plate 271 and covers the notch of the material preparation groove 265. When the injection molded part 250 moves to the loading position, the cover plate 231 moves to the right under the action of the first cylinder 232, exposing the material preparation groove 265 to facilitate loading.

Under the action of the first driving device, the first material picking head 310 and the second material picking head 340 can move in the front-to-back direction (i.e., the first direction), so that the first material picking head 310 and the second material picking head 340 move alternately to the pallet 500. The first material picking head 310 can approach or move away from the pallet 500 in the up-down direction (i.e., the second direction), so as to place the injection molded part 250 grabbed by the first material picking head 310 on the pallet 500, and the second material picking head 340 can approach or move away from the pallet 500 in the up-down direction, so as to place the injection molded part 250 grabbed by the second material picking head 340 on the pallet 500.

[0070] Specifically, the first driving device includes a ninth driving device 320 and a tenth driving device 330, the tenth driving device 330 is arranged on the output end of the ninth driving device 320, and the first material taking head 310 and the second material taking head 340 are both arranged on the output end of the tenth driving device 330. The ninth driving device 320 includes a first sensor assembly 321, a second motor 322, a screw rod, a nut, a mounting seat 323 and a second mounting plate 324, the second motor 322 is locked and fixed on the mounting seat 323, the mounting seat 323 is locked and fixed on the frame 900, one end of the screw rod is fixed on the rotating shaft of the second motor 322, the screw rod and the nut are threadedly matched, and the second mounting plate 324 is fixedly connected to the nut, thereby, driven by the second motor 322, the second mounting plate 324 will move in the front-rear direction.

[0071] The first sensor assembly 321 includes a first baffle 351, a first through-beam photoelectric sensor 352, and a second through-beam photoelectric sensor 353. The first baffle 351 is fixed relative to the second mounting plate 324. The first through-beam photoelectric sensor 352 and the second through-beam photoelectric sensor 353 are both fixed relative to the mounting seat 323. The first through-beam photoelectric sensor 352 is distributed at the front side, and the second through-beam photoelectric sensor 353 is distributed at the rear side. When the second mounting plate 324 moves in the front-to-back direction, the first baffle 351 moves with the second mounting plate 324, thereby triggering the first through-beam photoelectric sensor 352 or the second through-beam photoelectric sensor 353.

[0072] The tenth driving device 330 includes a fourth cylinder 331, a third sliding assembly 332 and a third mounting plate 333. The cylinder body of the fourth cylinder 331 is locked and fixed on the second mounting plate 324. The third mounting plate 333 is locked and fixed on the telescopic rod of the fourth cylinder 331. The first material picking head 310 and the second material picking head 340 are both locked and fixed on the third mounting plate 333. Driven by the fourth cylinder 331, the first material picking head 310 and the second material picking head 340 can move in the up and down directions.

[0073] In another embodiment, the ninth driving device 320 and the tenth driving device 330 may be replaced by linear motors.

[0074] Reference Fig.17 and Fig.18 , Fig.18 yes Figure 1 Exploded view of the first material picking head 310. The first material picking head 310 includes a first limiting plate 311, a first vacuum suction nozzle 312, a second elastic element and a first positioning seat 313. The first vacuum suction nozzle 312 can be connected to a negative pressure gas source to adsorb the injection molded part 250. In order to prevent the first vacuum suction nozzle 312 from having a strong collision with the injection molded part 250 when the first vacuum suction nozzle 312 grabs the injection molded part 250, a second elastic element is provided. The second elastic element gives the first vacuum suction nozzle 312 an elastic force to approach the support plate 500. When the first vacuum suction nozzle 312 approaches the support plate 500 downward, the first vacuum suction nozzle 312 shrinks upward. When the first vacuum suction nozzle 312 is away from the rear preparation plate 271, the first vacuum suction nozzle 312 returns to its original position, that is, the second elastic element plays a buffering role.

[0075] A guide post 364 is provided on the first vacuum suction nozzle 312, and a guide hole 366 is provided on the first positioning seat 313. The guide post 364 is inserted into the guide hole 366, and the guide post 364 and the guide hole 366 are clearance-matched. The size of the third limiting step 363 is larger than the guide hole 366, that is, the third limiting step 363 will abut against the lower end surface of the accommodating cavity 365, thereby preventing the first vacuum suction nozzle 312 from falling off the first positioning seat 313.

[0076] In this embodiment, the second elastic element is a second compression spring, the first positioning seat 313 is locked and fixed on the third mounting plate 333, a receiving cavity 365 is provided in the first positioning seat 313, the first vacuum suction nozzle 312 is placed in the receiving cavity 365, an air guide column 362 is provided on the first vacuum suction nozzle 312, a third limiting hole 361 is provided on the first limiting plate 311, after the second compression spring is sleeved on the air guide column 362, the air guide column 362 passes through the third limiting hole 361, and the first limiting plate 311 is locked and fixed on the upper end surface of the first positioning seat 313. As a result, the upper end of the second compression spring abuts against the first limiting plate 311, and the lower end of the second compression spring abuts against the third limiting step 363 of the first vacuum suction nozzle 312, thereby giving the first vacuum suction nozzle 312 a downward elastic force.

[0077] The air guide column 362 extends out from the third limiting hole 361, which is also beneficial for the first vacuum suction nozzle 312 to be connected to the negative pressure air source through the air pipe.

[0078] In another embodiment, the second elastic element may also be a bellows.

[0079] In this embodiment, in order to adsorb multiple injection molded parts 250 at one time, four first vacuum suction nozzles 312 are provided, and the four first vacuum suction nozzles 312 are arranged in parallel. Correspondingly, four third limiting holes 361 are provided on the first limiting plate 311, and four guide holes 366 are provided on the first positioning seat 313.

[0080] In other embodiments, the number of the first vacuum nozzles 312 may be other numbers, such as two, three, or five, etc., to match the width of the material strip.

[0081] The structure of the second material taking head 340 is completely the same as that of the first material taking head 310 , and will not be described again here.

[0082] Reference Fig.16 and Fig.17, combined with the above, the loading process of the loading device 300 is explained. First, the first material picking head 310 picks up the injection molded part 250 from the rear material preparation plate 271. At this time, the second material picking head 340 releases the injection molded part 250, and the injection molded part 250 is placed on the material belt on the pallet 500. Then, under the action of the fourth cylinder 331, the first material picking head 310 and the second material picking head 340 move upward together until the piston rod of the fourth cylinder 331 moves to the first stroke end point, and the first material picking head 310 is away from the rear material preparation plate 271, and the second material picking head 340 is away from the material belt on the pallet 500. Furthermore, under the action of the ninth driving device 320, the first material picking head 310 and the second material picking head 340 move backward together until the second beam-type photoelectric sensor 353 is triggered by the first baffle 351. At this time, the first material picking head 310 is located above the support plate 500, and the second material picking head 340 is located above the front material preparation plate 271. After that, the fourth cylinder 331 is actuated, and the first material picking head 310 and the second material picking head 340 move downward together until the piston rod of the fourth cylinder 331 moves to the second stroke end point. At this time, the injection molded part 250 on the first material picking head 310 has been placed on the material belt on the support plate 500, and the second material picking head 340 drives the front material preparation plate 271.

[0083] Then, the first material picking head 310 releases the injection molded part 250, and the second material picking head 340 sucks the injection molded part 250 from the front material preparation plate 271. Afterwards, under the action of the fourth cylinder 331, the first material picking head 310 and the second material picking head 340 move upward again until the piston rod of the fourth cylinder 331 moves to the first stroke end point, the first material picking head 310 is away from the material belt on the pallet 500, and the second material picking head 340 is away from the front material preparation plate 271. Then, under the action of the ninth driving device 320, the first material picking head 310 and the second material picking head 340 move forward together until the first beam-type photoelectric sensor 352 is triggered by the first baffle 351, at which time, the first material picking head 310 is located above the rear material preparation plate 271, and the second material picking head 340 is located above the pallet 500. Afterwards, under the action of the fourth cylinder 331, the first material head 310 and the second material head 340 move downward again until the piston rod of the fourth cylinder 331 moves to the second stroke end point, the first material head 310 reaches the rear material preparation plate 271, and the second material head 340 releases the injection molded part 250, and the injection molded part 250 is placed on the material belt on the support plate 500. At this point, one feeding action is completed, and the above feeding action can be repeated later.

[0084] Reference Figure 1 , Fig.19 and Fig. 20 , Fig.19 yes Figure 1 Axonometric view of the middle pressing device 400, Fig. 20 yes Figure 1Exploded diagram of the pressing device 400. In order to make the injection molded part 250 close to the material strip and the injection molded part 250 and the double-sided tape on the material strip closely fit, a pressing mechanism 400 is provided. The pressing mechanism 400 includes a second driving device, a guide plate 420, a guide rod 430, a second fixing seat 440 and a pressing mold 450. The guide plate 420 is fixed to the frame 900. The second driving device is fixed to the guide plate 420. A guide hole 421 is provided on the guide plate 420. The guide rod 430 is placed in the guide hole 421. The guide rod 430 and the guide hole 421 are clearance-matched. Through the guiding action of the guide rod 430 and the guide hole 421, the second fixing seat 440 can move in the up and down direction relative to the guide plate 420. The pressing mold 450 is fixed to the second fixing seat 440. The fixing method can be screw-locked.

[0085] Therefore, under the action of the second driving device, the pressing mold 450 can be close to the support plate 500, so that the injection molded part 250 is pressed tightly on the material belt, so that the injection molded part 250 and the double-sided tape are tightly fitted.

[0086] In this embodiment, the second driving device is the fifth cylinder 410. In other embodiments, the second driving device may also be a linear motor.

[0087] Reference Fig.21 , Fig. 22 and Fig.24 , Fig.21 yes Figure 1 Axonometric view of the middle material belt pusher 600, Fig. 22 yes Figure 1 Axonometric view of the middle support plate 500 and the positioning device 610, Fig.24 yes Figure 1 Axonometric view of the middle frame 900, the support plate 500 and the pushing device 620. The material belt pushing device of this embodiment includes a positioning device 610 and a pushing device 620. The positioning device 610 is used to temporarily fix the material belt on the support plate 500 to prevent the material belt from moving relative to the support plate 500, thereby ensuring accurate feeding of the injection molded parts. There are two positioning devices 610, and the two positioning devices 610 are arranged on the support plate 500 at intervals along the front and rear directions, thereby facilitating the positioning devices 610 to press the material belt together at the front and rear ends to prevent the material belt from arching in the middle. There is one pushing device 620, and the pushing device 620 is used to realize the conveying of the material belt when the positioning device 610 does not press the material belt tightly. The pushing device 620 is located at the rear side.

[0088] Reference Fig.21 , Fig.24 and Fig.25 , Fig.25 yes Figure 1Exploded view of the pushing device 620 in FIG. In order to enable the material strip to be pushed on the pallet 500 in stages, a pushing device 620 is provided, and the pushing device 620 includes a fourth driving device, a first clamping plate 623, a second clamping plate 624, a fifth driving device, and a second sensor assembly 627, wherein two first clamping blocks 642 are provided on the lower side of the first clamping plate 623, and the two first clamping blocks 642 are arranged at intervals along the left and right directions, and correspondingly, a second clamping block 643 is provided at the left and right ends of the second clamping plate 624, respectively. Under the action of the fourth driving device, the first clamping block 642 approaches the second clamping block 643, thereby clamping the material strip between the first clamping block 642 and the second clamping block 643. Under the action of the fifth driving device, the first clamping block 642 and the second clamping block 643 move backward relative to the pallet 500, thereby dragging the material strip on the pallet 500 backward for a distance.

[0089] By setting two first clamps 642, the two first clamps 642 are spaced apart in the left-right direction, and correspondingly, two second clamps 643 are set, one group of first clamps 642 and second clamps 643 clamp the left side of the material strip, and the other group of first clamps 642 and second clamps 643 clamp the right side of the material strip, thereby making the force on the material strip uniform. At the same time, the first clamps 642 can avoid the double-sided tape on the material strip to prevent the first clamps 642 from adhering to the double-sided tape.

[0090] In another embodiment, only one first clamping block 642 may be provided at the left end of the first clamping plate 623, and correspondingly, one second clamping block 643 may be provided at the left side of the second clamping plate 624, and the material strip may be dragged in this case. Alternatively, only one first clamping block 642 may be provided at the right end of the first clamping plate 623, and correspondingly, one second clamping block 643 may be provided at the right side of the second clamping plate 624, and the material strip may be dragged in this case.

[0091] In this embodiment, the fourth driving device includes a seventh cylinder 621 and a fifth mounting plate 622, the seventh cylinder body 633 of the seventh cylinder 621 is locked and fixed on the fifth mounting plate 622, the fifth mounting plate 622 is locked and fixed on the second clamping plate 624, and the first clamping plate 623 is locked and fixed on the seventh piston rod 634 of the seventh cylinder 621. Therefore, under the drive of the seventh cylinder 621, the first clamping block 642 can approach the second clamping block 643 to complete the clamping of the material strip. In addition, under the drive of the seventh cylinder 621, the first clamping block 642 can be away from the second clamping block 643, thereby releasing the material strip and preparing for the next clamping of the material strip.

[0092] In another embodiment, the seventh cylinder 621 in the fourth driving device can be replaced by a linear motor. In this case, the linear motor is locked and fixed on the second clamping plate 624 through the fifth mounting plate 622, and the first clamping plate 623 is fixed on the output end of the linear motor.

[0093] The fifth driving device includes a fourth sliding assembly 625, a third motor 626, a screw and a nut, one end of the screw is fixed to the rotating shaft of the third motor 626, the nut and the screw are threadedly matched, and the second clamping plate 624 is locked and fixed to the nut. Under the drive of the third motor 626, the first clamping block 642 and the second clamping block 643 can move backward, thereby dragging the material strip on the support plate 500 backward. In addition, under the drive of the third motor 626, the first clamping block 642 and the second clamping block 643 can move forward, thereby preparing for the next dragging of the material strip.

[0094] In order to guide the movement of the second clamping plate 624, a fourth sliding assembly 625 is provided. The fourth sliding assembly 625 includes a guide rail 635 and a slider 636. The guide rail 635 and the slider 636 are slidably matched. The guide rail 635 is locked and fixed on the frame 900, and the slider 636 is locked and fixed to the second clamping plate 624. Therefore, when the second clamping plate 624 moves in the front-back direction, the fourth sliding assembly 625 can play a guiding role. In addition, the fourth sliding assembly 625 can also play a load-bearing role, sharing the pressure borne by the third motor 626. In this embodiment, the fourth sliding assembly 625 is provided with two groups, and the two groups of the fourth sliding assembly 625 are respectively arranged on both sides of the support plate 500.

[0095] The second sensor assembly 627 includes a third through-beam photoelectric sensor 637 and a second baffle 638. The second baffle 638 is fixed on the nut, so that the second baffle 638 can move forward or backward together with the second clamp 643. Two third through-beam photoelectric sensors 637 are provided, and the two third through-beam photoelectric sensors 637 are arranged along the front-back direction. When the second baffle 638 triggers one of the third through-beam photoelectric sensors 637, the fifth driving device changes the movement direction of the second clamp 643, that is, when the third through-beam photoelectric sensor 637 located at the rear side is triggered, the second clamp 643 stops moving and changes from backward movement to forward movement, and when the third through-beam photoelectric sensor 637 located at the front side is triggered, the second clamp 643 stops moving and changes from forward movement to backward movement.

[0096] Reference Figure 21 to Figure 23 , Fig.23 yes Figure 1 Exploded view of the positioning device 610. The positioning device 610 includes an eleventh driving device and a third clamping plate 613. In this embodiment, the eleventh driving device includes a fourth mounting plate 611 and a sixth cylinder 612. The sixth cylinder body 631 of the sixth cylinder 612 is locked and fixed on the fourth mounting plate 611, the fourth mounting plate 611 is locked and fixed on the support plate 500, and the third clamping plate 613 is locked and fixed on the sixth piston rod 632 of the sixth cylinder 612. Therefore, under the drive of the sixth cylinder 612, the third clamping plate 613 can be close to or away from the support plate 500.

[0097] The third clamping plate 613 has the same structure as the first clamping plate 623, that is, two third clamping blocks 641 are arranged on the lower side of the third clamping plate 613, and the two third clamping blocks 641 are arranged at intervals in the left and right directions. By setting two spaced third clamping blocks 641, the third clamping block 641 can stably clamp the material strip after cooperating with the support plate 500, and at the same time, the third clamping block 641 can also avoid the double-sided tape on the material strip to prevent the third clamping block 641 from sticking to the double-sided tape.

[0098] Reference Figure 21 to Figure 25 When the third through-beam photoelectric sensor 637 located at the rear side is triggered by the second baffle 638, the second clamp 643 stops moving under the control of the fifth driving device. At the same time, the fourth driving device controls the first clamp 642 to move upward. The first clamp 642 and the second clamp 643 no longer clamp the material strip. The third clamp 641 moves downward under the control of the eleventh driving device. The third clamp 641 cooperates with the pallet 500 to press the material strip on the pallet 500 to prevent the material strip from moving. At this time, the loading process of the injection molded part 250 can be carried out. Afterwards, the second clamp 643 moves forward under the control of the fifth driving device until the second baffle 638 triggers the third through-beam photoelectric sensor 637 located at the front side. At this time, the first clamp 642 moves downward under the control of the fourth driving device. The first clamp 642 and the second clamp 643 cooperate to clamp the material strip. At the same time, the third clamp 641 moves upward under the control of the eleventh driving device, and the material strip is no longer clamped on the pallet 500. Then, the second clamping block 643 moves backward under the control of the fifth driving device until the second blocking piece 638 triggers the third through-beam photoelectric sensor 637 at the rear side for the second time, and the material belt is dragged backward on the pallet 500 for a certain distance. At this time, the action of loading the injection molded part 250 and dragging the material belt is completed. The above-mentioned action can be repeated for the subsequent loading of the injection molded part 250 and dragging of the material belt.

[0099] Reference Figure 1 , Fig.26 and Fig. 27 , Fig.26 yes Figure 1 Axonometric view of the cutting device 700, Fig. 27 yes Figure 1 The exploded view of the cutting device 700 is provided to cut the material strip that has been bonded to the injection molded part 250 and to realize the block discharging of the material strip for the convenience of stacking and transportation. The cutting device 700 includes a cutting mechanism and a pressing device. The cutting mechanism is used to cut the material strip, and the pressing device is used to assist in cutting. That is, when the cutting mechanism cuts the material strip, the pressing device presses the material strip tightly against the pallet 500, and the material strip will not move relative to the pallet 500, so that the cut of the material strip is more neat.

[0100] The cutting mechanism includes a sixth driving device, a mounting plate 720, a knife seat 730, a guide seat 740, a first cutter 750 and a second cutter 760. In this embodiment, the sixth driving device is a sixth cylinder 710. The cylinder body of the sixth cylinder 710 is locked and fixed on the frame 900 through the mounting plate 720. The knife seat 730 is locked and fixed on the telescopic rod of the sixth cylinder 710. The first cutter 750 is locked and fixed at the lower end of the knife seat 730, and the second cutter 760 is locked and fixed on the support plate 500. Therefore, under the drive of the sixth cylinder 710, the first cutter 750 can approach the second cutter 760 to cut the material strip passing between the first cutter 750 and the second cutter 760 on the support plate 500. Under the drive of the sixth cylinder 710, the first cutter 750 can be away from the second cutter 760 to complete the next cutting.

[0101] In order to make the first cutter 750 move more smoothly and accurately in the up and down directions and the cutting of the material strip more stable, a guide seat 740 is provided. The guide seat 740 is locked and fixed on the frame 900. A guide groove 741 is provided in the guide seat 740. The knife seat 730 is placed in the guide groove 741. Under the restriction of the guide groove 741, the knife seat 730 can slide in the up and down directions relative to the guide seat 740, and the movement is more stable.

[0102] In order to cut the material strip smoothly, the angle between the ends of the first cutter 750 and the second cutter 760 that are close to each other is an acute angle. Therefore, when the first cutter 750 and the second cutter 760 cut the material strip, they gradually cut the material strip from one side of the material strip. The first cutter 750 and the second cutter 760 have a more concentrated force on the material strip, ensuring smooth cutting.

[0103] In this embodiment, there is an acute angle between the end of the first cutter 750 close to the second cutter 760 and the horizontal plane, and the end of the second cutter 760 close to the first cutter 750 is parallel to the horizontal plane, thereby making the angle between the ends of the first cutter 750 and the second cutter 760 close to each other an acute angle.

[0104] In another embodiment, one end of the first cutter 750 close to the second cutter 760 may be parallel to the horizontal plane, and one end of the second cutter 760 close to the first cutter 750 may have an acute angle with the horizontal plane, thereby making the forces exerted on the material strip by the first cutter 750 and the second cutter 760 more concentrated, thereby ensuring smooth cutting.

[0105] In another embodiment, the sixth driving device may also be a linear motor, and the first cutter 750 is fixed on the output end of the linear motor.

[0106] The pressing device includes a seventh driving device and a pressing block 780. In the present embodiment, the seventh driving device is the eighth cylinder 770. The cylinder body of the eighth cylinder 770 is locked and fixed on the frame 900. The pressing block 780 is locked and fixed on the telescopic rod of the eighth cylinder 770. Driven by the eighth cylinder 770, the pressing block 780 can approach or move away from the support plate 500, thereby tightening or loosening the material strip.

The collecting mechanism 800 includes a suction mechanism 810, a tray mechanism 820, a material box 830 and a material box switching mechanism 840. In order to cooperate with the cutting mechanism 700 for cutting and prevent the material strip from being unsupported and in a state of sagging at one end, a tray mechanism 820 is provided. The tray mechanism 820 includes a tenth cylinder 821 and a tray 822. The tray 822 is fixed on the output end of the tenth cylinder 821. When the cutting mechanism 700 cuts the material strip, the tray 822 supports the material strip.

[0108] In order to ensure that the cut material strip can fall into the material box 830 and will not stay on the tray 822 when the tenth cylinder 821 drives the tray 822 to retract, a suction mechanism 810 is provided. The suction mechanism 810 includes a ninth cylinder 811, a suction nozzle mounting plate 812 and a second suction nozzle 813. The suction nozzle mounting plate 812 is fixed on the output end of the ninth cylinder 811, and the second suction nozzle 813 is fixed on the suction nozzle mounting plate 812. Driven by the ninth cylinder 811, the second suction nozzle 813 can approach the material strip and, under the action of air pressure, absorb the cut material strip, and then, under the action of the ninth cylinder 811, move the material strip upward and away from the tray 822.

[0109] In this embodiment, in order to firmly absorb the material belt, four second suction nozzles 813 are provided, and the four second suction nozzles 813 are evenly distributed on the suction nozzle mounting plate 812 .

[0110] In order to continuously receive materials and remove the injection molded parts 250 in time, two material boxes 830 are provided. In order to enable the two material boxes 830 to automatically receive materials in turn, a material box switching mechanism 840 is provided. The material box switching mechanism 840 includes an eleventh cylinder 841, a material box tray 842 and a sliding pair 843. The guide rail of the sliding pair 843 is fixed on the frame 900, and the material box 830 is fixed on the slider of the sliding pair 843. At the same time, the material box 830 is also fixed on the output end of the eleventh cylinder 841. Driven by the eleventh cylinder 841, the two material boxes 830 move on the guide rail and receive materials in turn.
