Description

TECHNICAL FIELD

[0001] The utility model relates to material belt cutting technical field, concretely relates to a material belt loading cutting device. BACKGROUND

[0002] In the field of electronic manufacturing, the chip mounting technology refers to a technology for precisely connecting a magnet and a pin (PIN). Generally, before the mounting operation is implemented, the incoming form of the pin (PIN) is mainly divided into two categories: one is a pin with a belt, and the pin with a belt exists in a belt shape, in which a plurality of pin needles are connected to each other through a sideband and a connecting piece for transportation and storage; the other is a single pin.

[0003] Due to the difference in the incoming form of the pin, the loading process and the loading device used are also different. In particular, for the pin with a belt, the pin needle is usually loaded together with the belt in the production link before the pin needle is mounted with the magnet, and then the pin needle is precisely cut and separated from the belt by a cutting device. After that, the mounting head is responsible for picking up the cut pin needles and continues to perform the subsequent mounting process.

[0004] The existing cutting device performs lifting movement through a mechanical structure (such as a blade or a punch) arranged above the belt to cut the pin on the belt in a physical way. However, after cutting, the mounting head needs to move to the cutting position to pick up the pin, at which time the blade or punch needs to be avoided. Therefore, it is necessary to improve the existing technology to meet the avoidance requirement of the blade or punch. In addition, in the case where the pin spacing is small or the pin shape is complex, how to ensure the accuracy of cutting is also a difficult problem. SUMMARY

[0005] The utility model aims at least solve the technical problem of how to ensure the accuracy of cutting under the premise of meeting the avoidance requirement of the blade or punch in the prior art.

[0006] Therefore, the utility model provides a material belt loading cutting device, which meets the avoidance requirement of the cutting knife and ensures the accuracy of cutting.

[0007] According to the material belt loading cutting device provided by the utility model, the cutting device comprises a cutting mechanism, a positioning mechanism and a loading mechanism.

[0008] The loading mechanism comprises a loading disc and a feeding assembly, the loading disc is wound with a material belt, and the material belt has at least one workpiece to be cut;

[0009] The positioning mechanism is used for positioning the material belt.

[0010] A cutting mechanism, comprising a cutting blade, the cutting blade being reciprocating along the z-axis direction, the cutting blade being used to cut off the workpiece to be cut;

[0011] A driving mechanism is provided to drive the cutting mechanism to reciprocate along the y-axis and z-axis directions.

[0012] The feeding assembly is used to drive the material belt to move and pass through the positioning mechanism, and the cutting blade shape of the cutting blade matches the contour of the workpiece to be cut.

[0013] The beneficial effects of this utility model are as follows: By driving the cutting mechanism to reciprocate along the y-axis and z-axis, the position of the cutting blade can be controlled more flexibly. This not only meets the cutting blade's avoidance requirements but also reduces the impact on the overall production process during avoidance, allowing the placement head to pick up workpieces more quickly and further improving production efficiency. The positioning mechanism positions the material strip, and two adjacent workpieces in the material strip are connected by connecting pieces. The cutting blade is equipped with a contour-designed cutting edge, which ensures that even when the spacing between adjacent workpieces is tight or the workpiece shape is complex, the contour-designed cutting edge can still effectively separate the connecting piece from the workpiece to ensure cutting accuracy. The entire material strip feeding and cutting device integrates the feeding mechanism, positioning mechanism, cutting mechanism, and driving mechanism to realize the material strip feeding and workpiece cutting process, improving the stability and controllability of the production process and facilitating large-scale, high-efficiency chip mounting production.

[0014] According to one embodiment of this utility model, the cutting mechanism further includes a cutting cylinder and a blade holder. The cutting cylinder is disposed on the moving end of the driving mechanism, and the blade holder is disposed on the cutting cylinder. The cutting cylinder drives the blade holder to reciprocate along the z-axis, and the cutting blade is disposed on the blade holder. Thus, by driving the cutting blade to move along the small z-axis via the cutting cylinder to perform the cutting action, and by driving the cutting mechanism to move along the large z-axis, the cutting or avoidance efficiency is improved through the combined action of the large and small z-axis.

[0015] According to one embodiment of the present invention, the positioning mechanism has a first positioning hole, and the cutting mechanism is provided with a first positioning pin for insertion into the first positioning hole. Thus, the cooperation between the first positioning hole and the first positioning pin allows the cutting blade to be precisely aligned with the workpiece to be cut during the descent of the blade holder, ensuring cutting precision and accuracy without the need for complex adjustments and calibrations.

[0016] According to one embodiment of the present invention, the positioning mechanism includes:

[0017] A positioning base, on which a lifting cylinder and a guide shaft are provided;

[0018] A positioning platform is provided at the upper end of the guide shaft. The positioning platform has a receiving channel along the y-axis for the material strip to pass through and a cutting channel along the z-axis. The receiving channel and the cutting channel are interconnected, and the cutting blade can be inserted into the cutting channel.

[0019] A lifting plate is mounted on the guide shaft via a linear bearing and connected to the moving end of the lifting cylinder. The lifting cylinder drives the lifting plate to reciprocate along the z-axis.

[0020] A cutting base is disposed on the lifting plate and located below the cutting channel. Vacuum adsorption holes are correspondingly provided on the cutting base, each corresponding to a workpiece to be cut, and are used to adsorb the workpiece. Thus, the lifting plate is driven to reciprocate along the z-axis by a lifting cylinder, which in turn moves the cutting base on the lifting plate. This allows the vacuum adsorption holes on the cutting base to accurately adsorb the workpiece, achieving precise workpiece positioning. Because the vacuum adsorption holes have precisely positioned the workpiece, the cutting blade can be inserted into the cutting channel to complete the cutting action more accurately and quickly. This design ensures the stability and accuracy of the workpiece during the cutting process, avoiding cutting errors caused by positioning deviations. Compared with mechanical clamping, the design of the vacuum adsorption holes will not cause scratches or indentations on the surface of the workpiece, which helps protect the quality of the workpiece. The design of the lifting cylinder and guide shaft provides a stable motion trajectory for the lifting plate, ensuring smooth and vibration-free reciprocating motion of the lifting plate in the z-axis direction.

[0021] According to one embodiment of this utility model, the material strip is provided with a plurality of first insertion holes at equal intervals along its length, the positioning platform is provided with a second positioning hole, and the lifting plate is provided with a second positioning pin. The second positioning pin can be operably inserted into the second positioning hole and then into any one of the first insertion holes on the material strip. Thus, the cooperation between the second positioning hole and the second positioning pin achieves further positioning between the lifting plate and the positioning platform. After the second positioning pin is operably inserted into the second positioning hole, it can also be further inserted into any one of the first insertion holes on the material strip. This design allows the lifting plate to accurately position the material strip through the second positioning pin before it drives the cutting base to adsorb the workpiece. This helps to avoid the material strip from shifting or misaligning during movement, ensuring accurate cutting of the workpiece and further improving the accuracy of workpiece adsorption by the vacuum adsorption hole.

[0022] According to one embodiment of this utility model, a waste material lower cutter is provided on the end face of the lifting plate facing the positioning platform, and a waste material upper cutter is provided on the end face of the positioning platform facing the lifting plate, which cooperates with the waste material lower cutter. Thus, through the up-and-down movement of the lifting plate and the cooperating waste material upper and lower cutters, the cutting and separation of waste material on the upper edge of the conveyor belt is achieved.

[0023] According to one embodiment of the present invention, a first waste material chute is provided on one side of the positioning mechanism, and the first waste material chute is close to the waste material cutting blade. Thus, by providing the first waste material chute, waste material on the upper edge of the conveyor belt is discharged outside the equipment, preventing waste material accumulation from affecting equipment operation.

[0024] According to one embodiment of this utility model, a discharge hole is provided on the cutting base, and a second waste slide is provided on the other side of the positioning mechanism, the second waste slide communicating with the discharge hole. Thus, by providing the discharge hole and the second waste slide, the waste material from the connecting piece between two adjacent workpieces is discharged outside the equipment, preventing waste accumulation from affecting equipment operation.

[0025] According to one embodiment of the present invention, the feeding assembly includes:

[0026] A ratchet, wherein a plurality of pins are equally spaced along its circumference on its outer peripheral surface, and a plurality of second insertion holes for inserting the pins are equally spaced along its length on the strip.

[0027] A stepper motor is mounted on a motor mounting base and is used to drive the ratchet to rotate around the x-axis;

[0028] A feeding plate is mounted on the motor mounting base. The feeding plate has a guide channel along the y-axis for conveying the material strip. The ratchet rotates, causing the material strip within the guide channel to move. Thus, through the cooperative design of the pins on the ratchet and the second insertion holes, the pins on the outer circumference of the ratchet can accurately insert into the equally spaced second insertion holes on the material strip, allowing the material strip to move smoothly along the guide channel when the ratchet rotates. Combined with the precise control of the stepper motor, this ensures the stability and accuracy of the material strip during the feeding process, avoiding cutting errors or workpiece damage caused by feeding deviations.

[0029] According to one embodiment of the present invention, the driving mechanism includes:

[0030] A servo motor, wherein the servo motor is mounted on a motor base;

[0031] A Y-axis lead screw, which is directly connected to the servo motor;

[0032] A nut seat module, which is threadedly connected to the y-direction lead screw;

[0033] An electric cylinder is mounted on the nut seat module, and the cutting mechanism is mounted on the electric cylinder. The electric cylinder drives the cutting mechanism to move along the z-axis. Therefore, by precisely controlling the parameters of the servo motor, precise control of the position of the nut seat module on the y-axis lead screw can be achieved, thereby ensuring high-precision positioning of the cutting mechanism in the y-axis direction. The electric cylinder also drives the cutting mechanism to move rapidly along the large z-axis, improving production efficiency, ensuring the movement accuracy of the cutting mechanism, and making the cutting operation more accurate and stable.

[0054] Example 1:

[0055] like Figures 1 to 9 The diagram shows a preferred embodiment of the present invention. The material strip feeding and cutting device of this embodiment includes: a feeding mechanism 2, a positioning mechanism 3, a cutting mechanism 4, and a driving mechanism 5. The feeding mechanism 2 includes a feeding tray 201 and a feeding assembly. A material strip 1 is wound on the feeding tray 201. The material strip 1 has at least one workpiece 101 to be cut. Specifically, the material strip 1 has several groups of workpieces 101 along its length, and each group of workpieces 101 includes multiple workpieces 101 to be cut. The positioning mechanism 3 is used to position the material strip 1. The cutting mechanism 4 includes a cutting blade 401, which can reciprocate along the z-axis. The cutting blade 401 is used to cut the workpiece 101 to be cut. The driving mechanism 5 is used to drive the cutting mechanism 4 along the y-axis and z-axis (see...). Figure 1 As shown, in this embodiment, the up-down direction is defined as the z-axis, the direction from the upper left to the lower right is defined as the y-axis, and the direction from the lower left to the upper right is defined as the x-axis for ease of explanation, and the movement direction and setting direction of the cutting mechanism 4 are not actually limited.

[0056] The feeding assembly drives the material belt 1 to move along the y-axis (in this embodiment, the direction from the upper left to the lower right is defined as the y-axis for ease of explanation, and does not actually limit the movement direction and setting direction of the material belt 1) and passes through the positioning mechanism 3. The cutting blade 401 is a contouring blade, and the cutting edge of the cutting blade 401 is contoured. For details, see [link to documentation]. Figure 3 As shown, two adjacent workpieces 101 in the strip 1 are connected by a connecting piece. Thus, when the cutting blade 401 cuts along the z-axis, it separates the connection between the connecting piece and the workpiece 101.

[0057] In this embodiment, the cutting mechanism 4 further includes a cutting cylinder 402 and a blade holder 403. The cutting cylinder 402 is mounted on the moving end of the drive mechanism 5, and the blade holder 403 is mounted on the cutting cylinder 402. The cutting cylinder 402 drives the blade holder 403 to reciprocate along the z-axis, and the cutting blade 401 is mounted on the blade holder 403. Thus, the cutting cylinder 402 drives the cutting blade 401 to move along the small z-axis to perform the cutting action, and the drive mechanism 5 drives the cutting mechanism 4 to move along the large z-axis. With the dual cooperation of the large and small z-axis, the cutting or avoidance efficiency is improved.

[0058] In this embodiment, the positioning mechanism 3 has a first positioning hole 301, and the cutting mechanism 4 is provided with a first positioning pin 404 for inserting into the first positioning hole 301. Thus, the cooperation between the first positioning hole 301 and the first positioning pin 404 allows the cutting blade 401 to be precisely aligned with the workpiece 101 to be cut during the descent of the blade holder 403, ensuring cutting precision and accuracy without the need for complex adjustments and calibrations.

[0059] In this embodiment, the drive mechanism 5 includes:

[0060] Servo motor 501 is mounted on motor base 502;

[0061] Y-axis lead screw 503, which is directly connected to servo motor 501;

[0062] Nut seat module 504 is threadedly connected to the Y-axis lead screw 503;

[0063] An electric cylinder 505 is mounted on the nut seat module 504, and the cutting mechanism 4 is mounted on the electric cylinder 505. The electric cylinder 505 drives the cutting mechanism 4 to move along the z-axis. Therefore, by precisely controlling the parameters of the servo motor 501, precise control of the position of the nut seat module 504 on the y-axis lead screw 503 can be achieved, thereby ensuring high-precision positioning of the cutting mechanism 4 in the y-axis direction. The electric cylinder 505 can drive the cutting mechanism 4 to move rapidly along the large z-axis, improving production efficiency, ensuring the movement accuracy of the cutting mechanism 4, and making the cutting operation more accurate and stable.

[0064] In this embodiment, the positioning mechanism 3 includes:

[0065] Positioning base 302, on which a lifting cylinder 303 and a guide shaft 304 are provided;

[0066] Positioning platform 305 is located at the upper end of guide shaft 304. Positioning platform 305 has a receiving channel 306 for the feeding belt 1 to pass through along the y-axis and a cutting channel 307 along the z-axis. The receiving channel 306 and the cutting channel 307 are connected to each other. Cutting blade 401 can be inserted into cutting channel 307.

[0067] The lifting plate 308 is mounted on the guide shaft 304 via a linear bearing and is connected to the moving end of the lifting cylinder 303. The lifting cylinder 303 drives the lifting plate 308 to reciprocate along the z-axis.

[0068] The cutting base 309 is disposed on the lifting plate 308 and located below the cutting channel 307. The cutting base 309 is provided with vacuum adsorption holes 310, which correspond to each workpiece 101 to be cut and are located on both sides of the bottom surface of the workpiece 101 to be cut, so as to adsorb the workpiece 101 to be cut. Therefore, the lifting cylinder 303 drives the lifting plate 308 to reciprocate along the z-axis, which in turn moves the cutting base 309 on the lifting plate 308. This allows the vacuum adsorption hole 310 on the cutting base 309 to accurately adsorb the workpiece 101 to be cut, achieving precise positioning of the workpiece 101. Since the vacuum adsorption hole 310 has accurately positioned the workpiece 101, the cutting blade 401 can be inserted into the cutting channel 307 to complete the cutting action more accurately and quickly. This design ensures the stability and accuracy of the workpiece 101 during the cutting process and avoids cutting errors caused by positioning deviations. Compared with mechanical clamping, the design of the vacuum adsorption hole 310 will not cause scratches or indentations on the surface of the workpiece 101, which is beneficial to protecting the quality of the workpiece 101. The design of the lifting cylinder 303 and the guide shaft 304 provides a stable motion trajectory for the lifting plate 308, ensuring that the reciprocating motion of the lifting plate 308 in the z-axis direction is smooth and vibration-free.

[0069] In this embodiment, the strip 1 has several first insertion holes 102 evenly spaced along its length. The positioning platform 305 has second positioning holes 311, and the lifting plate 308 is provided with a second positioning pin 312. The second positioning pin 312 can be operably inserted into the second positioning hole 311 and then into any one of the first insertion holes 102 on the strip 1. Thus, the cooperation between the second positioning hole 311 and the second positioning pin 312 achieves further positioning between the lifting plate 308 and the positioning platform 305. After the second positioning pin 312 is operably inserted into the second positioning hole 311, it can also be further inserted into any one of the first insertion holes 102 on the strip 1. This design allows the lifting plate 308 to accurately position the strip 1 through the second positioning pin 312 before driving the cutting base 309 to adsorb the workpiece 101. This helps to avoid the strip 1 from shifting or misaligning during movement, ensuring accurate cutting of the workpiece 101 and further improving the accuracy of the vacuum adsorption hole 310 adsorbing the workpiece 101.

[0070] In this embodiment, the feeding assembly includes:

[0071] Ratchet 202, with a plurality of pins 203 evenly spaced along its circumference on its outer peripheral surface, and a plurality of second insertion holes 103 for inserting the pins 203 evenly spaced along its length of the material strip 1.

[0072] Stepper motor 204 is mounted on motor mounting base 205 and is used to drive ratchet 202 to rotate around the x-axis;

[0073] A feeding plate 206 is mounted on a motor mounting base 205. A guide channel 207 for conveying the material belt 1 is formed along the y-axis on the feeding plate 206. The ratchet 202 rotates, causing the material belt 1 to move within the guide channel 207. Thus, through the cooperative design of the pins 203 on the ratchet 202 and the second insertion holes 103, the pins 203 on the outer circumference of the ratchet 202 can be precisely inserted into the equally spaced second insertion holes 103 on the material belt 1. This allows the material belt 1 to move smoothly along the guide channel 207 when the ratchet 202 rotates. Combined with the precise control of the stepper motor 204, this ensures the stability and accuracy of the material belt 1 during the feeding process, avoiding cutting errors or damage to the workpiece 101 caused by feeding deviations.

[0074] Example 2:

[0075] Based on Embodiment 1, the following addition is made: a waste material lower cutter 313 is provided on the end face of the lifting plate 308 facing the positioning platform 305, and a waste material upper cutter 314 that cooperates with the waste material lower cutter 313 is provided on the end face of the positioning platform 305 facing the lifting plate 308. Thus, through the up and down movement of the lifting plate 308 and the cooperating waste material upper cutter 314 and waste material lower cutter 313, the cutting and separation of the waste material on the upper edge of the material belt 1 is achieved.

[0076] In this embodiment, a first waste chute 315 is provided on one side of the positioning mechanism 3, and the first waste chute 315 is close to the waste cutting blade 313. Specifically, a first waste box for receiving edge waste is placed below the first waste chute 315. Thus, by setting the first waste chute 315, the edge waste on the conveyor belt 1 is discharged outside the equipment, avoiding the accumulation of waste and affecting the operation of the equipment.

[0077] In this embodiment, a discharge hole 316 is provided on the cutting base 309, and a second waste slide 317 is provided on the other side of the positioning mechanism 3. The second waste slide 317 is connected to the discharge hole 316. Specifically, a second waste box for receiving connecting piece waste is placed below the second waste slide 317. Thus, by providing the discharge hole 316 and the second waste slide 317, the connecting piece waste between two adjacent workpieces 101 is discharged outside the equipment, avoiding waste accumulation that may affect the operation of the equipment.

[0078] Example 3:

[0079] In this embodiment, the feeding mechanism 2 further includes a base plate 208 and a profile support 209. The profile support 209 is disposed on the base plate 208, and the feeding tray 201 is rotatably mounted on the profile support 209. Thus, the design of the base plate 208 and the profile support 209 ensures the stability and reliability of the feeding mechanism 2, making the feeding tray 201 more stable during use.

[0080] The working principle of this utility model is as follows:

[0081] The feed strip 1 is pulled out from the feed tray 201 and enters the guide channel 207. Inside the guide channel 207, the stepper motor 204 drives the ratchet 202 to rotate around the x-axis. The pins 203 on the outer circumference of the ratchet 202 can be inserted into the second insertion hole 103 on the feed strip 1, thereby driving the feed strip 1 to move along the guide channel 207. Until the feed strip 1 moves into the receiving channel 306 and the workpiece 101 to be cut moves above the cutting base 309, the lifting cylinder 303 activates the lifting plate 308. The cutting base 309 on the lifting plate 308 rises synchronously until the second positioning pin 312 is inserted into the second positioning hole 311 and then into the first insertion hole 102 on the material strip 1. At this time, the vacuum adsorption hole 310 adsorbs the corresponding strip cutting workpiece 101, thus realizing the positioning operation of the material strip 1 and the strip cutting workpiece 101 on the material strip 1. (It should be noted that when the lifting plate 308 rises, the waste lower cutter 313 moves upward and cooperates with the waste upper cutter 314.) The waste material on the edge of the material strip 1 is cut and separated, and the cut waste material is discharged from the device through the first waste material chute 315. The servo motor 501 starts and drives the nut seat module 504 and the cutting mechanism 4 to move above the cutting channel 307. The electric cylinder 505 drives the cutting mechanism 4 to descend until the first positioning pin 404 is inserted into the first positioning hole 301, realizing the positioning of the cutting blade 401. The cutting cylinder 402 is started, and the cutting blade 401 completes the cutting operation in the cutting channel 307. The vacuum adsorption hole 310 on the cutting base 309 adsorbs the cut workpiece 101, and the waste connecting piece is discharged from the device through the discharge hole 316 and the second waste slide 317. After the cutting cylinder 402 drives the cutting blade 401 to reset, the electric cylinder 505 drives the cutting mechanism 4 to reset, and the servo motor 501 drives the nut seat module 504 to reset, the mounting head moves to the top of the cutting base 309 to pick up the cut workpiece 101, and the lifting cylinder 303 drives the lifting plate 308 to reset. The above process is repeated to realize the cutting operation of the workpiece 101 on the material belt 1.
