Description

Technical Field

[0001] The invention relates to a cutting device, in particular to a cutting device for an inductor protection carrier tape. Background Art

[0002] The carrier tape is a strip-shaped component that carries electronic components. It is used together with the upper sealing tape to carry and store electronic components such as inductors, resistors, capacitors, diodes, etc., and form a closed package through the upper sealing tape. The cutting device is a device used to cut the carrier tape to a fixed length during mounting.

[0003] Existing cutting devices for carrier tapes generally include a guide transport structure for guiding the unrolled carrier tape and a cutting knife for automatically cutting the carrier tape transported to a certain length. For example, a patent for a cutting device for a carrier tape for electronic component packaging (Announcement No. CN213562847U) discloses a device capable of guiding and limiting the carrier tape to improve the cutting accuracy of the carrier tape, thereby avoiding the influence of the left and right displacement of the carrier tape. However, the setting of such a guide transport structure also results in that when unrolling, the first section of the carrier tape needs to be manually inserted into the guide groove, which is time-consuming and laborious. In particular, the carrier tape is generally soft in texture. When the length of the guide groove needs to be set longer, it is necessary to manually insert the first section of the carrier tape into the guide groove when changing the roll. It takes a long time to guide and position the first section of the carrier tape, especially in large workshops with automated processing. For example, the carrier tape described in a patent for a component carrier tape (publication number CN101346287) has additional advancement holes on the edge to assist in guiding and advancing the carrier tape, thereby further improving the degree of automation in the carrier tape processing. Automated cutting can improve the production efficiency of the carrier tape, that is, a roll of carrier tape can be cut and processed in less time. However, this is accompanied by the need for frequent shutdowns for roll changing operations. In the traditional manual roll changing method, the manual guided conveying of the first section of material loading takes a long time, which will also affect the overall production line processing efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a cutting device for inductor protective carriers, which can assist manual work in the automated cutting process to guide and position the first section of the carrier more conveniently and quickly, thereby improving the processing efficiency of the overall processing procedure.

[0005] The present invention provides the following technical solutions:

[0006] A cutting device for an inductance protection carrier tape, comprising a roll changing part and a guiding and cutting part. The roll changing part includes a sliding table, a carrier tape supporting plate and a unwind rack. The guiding and cutting part includes a guiding groove and a cutting knife. The sliding table is placed on the workbench and is used to reciprocate horizontally along the workbench to drive the two groups of carrier tape supporting plates above it to alternately dock with the guiding groove. Two unwind racks are respectively arranged on one side of the two groups of carrier tape supporting plates for installing carrier tape racks. A guiding wheel for guiding the carrier tape is also arranged on the bottom side of the unwind rack. After the carrier tape wound on the carrier tape rack passes through the guiding wheel, its first section is pressed and positioned at one end of the carrier tape supporting plate by a locking rod, and then slides longitudinally into the guiding groove along with the carrier tape supporting plate. When the carrier tape supporting plate passes through the guiding groove and is aligned with the alignment holes on the guiding groove, the carrier tape supporting plate and the guiding groove are locked in position by a positioning column passing through the alignment holes, and the locking rod is removed from the carrier tape supporting plate to facilitate the fixed-length transmission of the carrier tape;

[0007] The guiding groove includes a bottom plate, side plates, a left guiding channel and a right guiding channel. The two groups of side plates are oppositely installed on both sides of the bottom plate, and two groups of oppositely arranged left guiding channels and right guiding channels are fixed on the inner sides. There is a bottom gap between the left guiding channel and the right guiding channel and the bottom plate for the two sunken bases on both sides of the carrier tape supporting plate to pass through. An intermediate channel for the middle raised base of the carrier tape supporting plate to pass through is formed between the left guiding channel and the right guiding channel. The bottom gap and the intermediate channel form a passing gap for the carrier tape supporting plate to pass through. Oppositely arranged guiding slot openings are also provided on the left guiding channel and the right guiding channel. The guiding slot openings are used for guiding and limiting both sides of the carrier tape, and their bottom sides are flush with the middle raised base for supporting the carrier tape. The cutting knife is installed at the tail end of the guiding groove, and after the carrier tape supporting plate drives the first section of the carrier tape out of the guiding groove, it is used to cut the carrier tape advancing a fixed length. The cut carrier tape breaks away from the carrier tape supporting plate and falls into the collection groove below;

[0008] The specific cutting method for the first section of the carrier tape at this time is as follows: After the carrier tape supporting plate and the alignment holes on the guiding groove are aligned and locked, given the known distance between the cutting knife and the first section of the carrier tape, continuously pull the carrier tape forward until the carrier tape on the right side of the cutting knife reaches the standard length of the fixed-length carrier tape, then the cutting knife can be driven to cut the carrier tape. For the subsequent carrier tape, a cutting action can be performed by driving it once at a fixed length. Keep this continuous action until the cutting of the fixed-length of a roll of carrier tape is completed. Then, by replacing the carrier tape supporting plate aligned with the guiding groove, the rapid replacement of the old and new carrier tape racks can be realized. During the replacement, since the new carrier tape rack is carried out while the old carrier tape rack is performing the carrier tape cutting operation, the time for replacing the carrier tape rack can be saved, and the overall processing efficiency can be improved. And during the replacement, only the carrier tape supporting plate that has completed the carrier tape transmission needs to be pulled out of the guiding groove, then slide the sliding table, align the new carrier tape supporting plate with the guiding groove, and then drive the carrier tape supporting plate to slide into the guiding groove to complete the guiding of the first section of the carrier tape, which is more convenient and has better reliability and stability.

[0009] Preferably, the sliding table is driven by an electric cylinder on the workbench to reciprocate horizontally, and the carrier tape support plate is driven by an electric push cylinder to reciprocate longitudinally, thereby improving the automation level during the replacement of the old and new carrier tape racks, saving the time for manual replacement of the carrier tape racks, and thus improving the overall production efficiency of carrier tape processing.

[0010] Preferably, notches for installing two groups of automatic material pushing structures are also provided on the left guide path and the right guide path in the middle of the guide groove. The automatic material pushing structures are distributed on both sides of the carrier tape support plate and are used to clamp the carrier tape to make it advance a fixed length along the carrier tape support plate. Two groups of pressing cylinders are also arranged on both sides of the automatic material pushing structures. The pressing cylinders are installed on the left guide path and the right guide path and are used to press and position the carrier tape when the automatic material pushing structure relaxes and retreats. Since the two groups of automatic material pushing structures are distributed on both sides of the carrier tape support plate, the carrier tape can be synchronously clamped to drive the forward movement of the carrier tape, making the force on the carrier tape more balanced during movement, and thus further improving the stability of the carrier tape movement.

[0011] Preferably, the automatic material pushing structure includes a reciprocating groove block, a clamping block, a clamping cylinder, and a driving bar. The reciprocating groove block is laterally slidably connected to the side plate through a sliding block and is driven to reciprocate by a lead screw threadedly connected in the sliding block. The lead screw is rotatably connected to the left guide path or the right guide path and is driven to rotate by a lead screw motor. A plurality of alignment grooves are provided on the opposite sides of the two groups of reciprocating groove blocks. A driving block is slidably connected in the alignment grooves, and a support body flush with the middle convex base is extended outward from the bottom side of the driving block. The clamping blocks are connected to the driving blocks one by one, and the bottom sides thereof are relatively matched with the support body to clamp the carrier tape located therein and drive the carrier tape to advance under the drive of the lead screw. An inclined sliding surface one is provided on the top side thereof. A plurality of guide rods fixedly connected to the driving bar are provided on the reciprocating groove block, and a driving motor for driving the driving bar to move along the guide rods through a screw is provided. The screw is threadedly connected in the driving bar, and one end thereof is rotatably connected in the reciprocating groove block and is drivingly connected to the driving motor. An inclined sliding surface two slidably matched with the inclined sliding surface one is also provided on the bottom side of the driving bar. The moving direction of the driving bar along the guide rods is perpendicular to the moving direction of the clamping block. When the driving motor drives the screw to rotate, the driving bar can be driven to move along the guide rods, and then through the sliding cooperation of the inclined sliding surface one and the inclined sliding surface two, the clamping block is driven to move in a direction perpendicular to the guide rods to cooperate with the support body to limit the carrier tape.

[0012] Preferably, a pushing column is also provided on the bottom side of the clamping block. The pushing column is used for plugging and cooperating with the pushing holes on both sides of the carrier tape to plug and position the carrier tape, so that it can be more stable when clamping the carrier tape and driving it forward.

[0013] Preferably, a protective sleeve is also provided on the bottom side of the clamp block and surrounds the outside of the propulsion column. The top end of the protective sleeve is limited in the protective slot of the clamp block, and the protective sleeve is pressed against the outside of the propulsion column by a pressure spring arranged in the protective slot. Therefore, when the clamp block compresses the carrier tape, elastic compression of the carrier tape can be indirectly achieved through the protective sleeve, and the propulsion column in the protective sleeve can extend out of the protective sleeve and be positioned in the propulsion hole of the carrier tape. At the same time, when the clamp block releases the carrier tape, the protective sleeve can also serve as a structure to block the carrier tape, preventing the carrier tape from getting stuck in the propulsion column and rising with the propulsion column, thereby affecting the retreat of the automatic pushing structure. That is, if the propulsion column rises after being stuck in the propulsion hole, the carrier tape can be separated from the propulsion column under the pressure of the protective sleeve and the pressure spring.

[0014] Preferably, the locking rod includes a positioning pressure rod and a locking screw rod, the top end of the positioning pressure rod is provided with a transfer block connected to the locking screw rod, and the locking screw rod is provided with an external thread that is threadedly connected to the middle raised base of the carrier support plate.

[0015] Preferably, the cutting knife includes a knife rod, a connecting block, a knife body, and a screw-connected rod. Two sets of screw-connected rods are rotatably connected to the tail ends of the left guide and the right guide, and one end of each of the screw-connected rods is connected to a screw-connected motor drive. The connecting blocks connected to the two ends of the knife rod are threadedly connected to the outside of the screw-connected rod, and the knife rod and the knife body on the knife rod are driven to rise and fall by the screw-connected rod. The knife body passes through the left guide and the right guide to cut the carrier tape in the guide groove.

[0016] Preferably, a limiting groove is further provided at one end of the carrier support plate for positioning the first section of the carrier, and limiting blocks are slidably connected in two sets of limiting grooves that are symmetrically distributed. The limiting blocks include auxiliary supporting blocks that are connected to both sides of the central raised base and limiting plates for limiting on both sides of the carrier. Before the first section of the carrier is positioned, the limiting blocks can be inserted into the limiting grooves so that the carrier can be quickly limited to the middle position of the carrier support plate. After the first section of the carrier is locked by using the locking rod, the limiting block can be taken out and the carrier support plate can be waited for to be alternated. When this carrier support plate is aligned with the guide groove, it is only necessary to manually support the first section of the carrier to enter the guide groove when introducing the carrier support plate, and the subsequent operation is carried out by the carrier support plate, which is more convenient.

[0017] The beneficial effects of the present invention are:

[0018] 1. The two groups of carrier support plates arranged on the roll changing section slide are used to alternately dock with one end of the guide groove of the guide cutting section, so that when one group of carrier support plates positions one end of the carrier and stretches the carrier to slide into the guide groove for positioning, the other group of carrier support plates can be manually operated to position one end of the new unrolled carrier to wait for the previous roll of carrier to be cut and then directly alternate positions, thereby saving the waiting time for roll changing. The carrier is driven by the carrier support plate to pass through the guide groove, which is more convenient and more stable than manually limiting the carrier in the longer guide groove.

[0019] 2. An automatic feeding structure can be arranged in the middle of the guiding groove. The automatic feeding structure is used to drive the carrier tape to advance at a fixed length, and assist the cutting knife on the guiding groove to achieve automatic cutting once after each advancement, so as to achieve an automatic cutting effect and better cutting stability;

[0020] 3. The automatic feeding structure advances by clamping the carrier tape side by side with multiple groups of clamping blocks. Compared with only driving a group of clamping blocks to clamp the carrier tape by a group of clamping cylinders, the stability is better. Because the setting of multiple groups of clamping blocks can disperse the driving force for driving the carrier tape to advance, and drive in multiple points in cooperation, the probability of tensile fracture when driven forward by a single point can be reduced. And the clamping force of multiple groups of clamping blocks is driven and clamped by a group of long strip-shaped driving bars, and the movement mode of the driving bar is perpendicular to the direction of the clamping force. Therefore, only by driving the movement of the driving bar by a group of clamping cylinders to provide clamping force for the clamping blocks, the situation that the driving force decreases successively from the clamping end of the clamping cylinder to both sides will not occur, and it can ensure that each group of clamping blocks can have an average and stable clamping force, so as to improve the stability of the carrier tape advancing and avoid the risk of the carrier tape breaking during advancement;

[0021] 4. The clamping block is provided with a pushing column for positioning in the advancing hole of the carrier tape, so as to ensure the length of the carrier tape advancing at a fixed length, and further prevent the phenomenon of uneven cutting length caused by the carrier tape slipping during advancement. And the cooperation of the structure in this way with the clamping block and the driving bar structure can also avoid that when the pushing column is inserted into the advancing hole, different advancing holes will receive different sizes of lateral pushing forces, resulting in the tearing and breaking of the advancing hole with excessive force. That is, the uniformity effect of the clamping force can achieve balanced force on multiple groups of advancing holes when the carrier tape shows a tendency to slip and the advancing hole is laterally stressed, so as to reduce the risk of the carrier tape being torn and broken;

[0022] 5. The carrier tape support plate can be manually pushed to slide into or out of the guiding groove, or can be driven by an electric push cylinder to achieve automatic sliding in or out. When manually sliding in or out, the positioning column can be inserted between one end of the guiding groove and the guiding support plate for auxiliary positioning. That is, after the carrier tape support plate slides to a certain position, the alignment holes on the carrier tape support plate and the guiding groove are aligned. At this time, the positioning column is inserted into the two groups of alignment holes, and the carrier tape support plate and the guiding groove can be positioned and fixed.

[0041] Embodiment 1

[0042] As shown Figures 1-6 in the figure, a cutting device for an inductance protection carrier tape includes a roll changing part and a guiding and cutting part in this embodiment. The roll changing part includes a sliding table 1, a carrier tape supporting plate 2, and a unwind rack 3. The guiding and cutting part includes a guiding groove 4 and a cutting knife 5. The sliding table 1 is placed on the workbench and is used to reciprocate horizontally along the workbench to drive the two groups of carrier tape supporting plates 2 above it to alternately dock with the guiding groove 4. The two unwind racks 3 are respectively arranged on one side of the two groups of carrier tape supporting plates 2 for installing the carrier tape rack 7. A guiding wheel 6 for guiding the carrier tape 10 is also provided on the bottom side of the unwind rack 3. After the carrier tape 10 wound on the carrier tape rack 7 passes around the guiding wheel 6, its first section is pressed and positioned at one end of the carrier tape supporting plate 2 by a locking rod 8, and then slides longitudinally into the guiding groove 4 along with the carrier tape supporting plate 2. When the carrier tape supporting plate 2 passes out of the guiding groove 4 and the carrier tape supporting plate 2 is aligned with the alignment holes on the guiding groove 4, the carrier tape supporting plate 2 and the guiding groove 4 are locked in position by a positioning post 9 passing through the alignment holes, and the locking rod 8 is removed from the carrier tape supporting plate 2 to facilitate the fixed-length transmission of the carrier tape 10;

[0043] The guiding groove 4 includes a bottom plate 41, side plates 42, a left guiding channel 43, and a right guiding channel 44. The two side plates 42 are oppositely installed on both sides of the bottom plate 41, and two relatively arranged left guiding channels 43 and right guiding channels 44 are fixed on their inner sides. There is a bottom gap between the left guiding channel 43 and the right guiding channel 44 and the bottom plate 41 for the two concave bases on both sides of the carrier tape supporting plate 2 to pass through. An intermediate channel for the middle convex base of the carrier tape supporting plate 2 to pass through is formed between the left guiding channel 43 and the right guiding channel 44. The bottom gap and the intermediate channel form a passing gap for the carrier tape supporting plate 2 to pass through. Oppositely arranged guiding slot openings 45 are also provided on the left guiding channel 43 and the right guiding channel 44. The guiding slot openings 45 are used to guide and limit the two sides of the carrier tape 10, and their bottom sides are flush with the middle convex base for supporting the carrier tape 10. The cutting knife 5 is installed at the end of the guiding groove 4, and after the carrier tape supporting plate 2 drives the first section of the carrier tape 10 out of the guiding groove 4, it is used to cut the carrier tape 10 that advances a fixed length. The cut carrier tape 10 is separated from the carrier tape supporting plate 2 and falls into the collection tank below.

[0044] The sliding table 1 is driven by an electric cylinder on the workbench to reciprocate horizontally, and the carrier tape supporting plate 2 is driven by an electric push cylinder to reciprocate longitudinally, thereby improving the automation level during the replacement of the old and new carrier tape racks 7, saving the time for manual replacement of the carrier tape rack 7, and thus improving the overall production efficiency of the carrier tape 10 processing.

[0045] Notches 46 for installing two sets of automatic pushing structures 100 are also provided on the left guide 43 and the right guide 44 in the middle of the guide groove 4. The automatic pushing structures 100 are distributed on both sides of the carrier support plate 2 and are used to clamp the carrier 10 so that it can move a fixed distance along the carrier support plate 2. Two sets of clamping cylinders 200 are also provided on both sides of the automatic pushing structure 100. The clamping cylinders 200 are installed on the left guide 43 and the right guide 44, and are used to press the carrier 10 to position it when the automatic pushing structure 100 relaxes the carrier 10 and retreats. Since the two sets of automatic pushing structures 100 are structures distributed on both sides of the carrier support plate 2, they can synchronously clamp the carrier 10 to drive the carrier 10 forward, so that the force on the carrier 10 is more balanced when it moves, thereby further improving the stability of the movement of the carrier 10.

[0046] The automatic pushing structure 100 includes a reciprocating groove block 101, a clamping block 102, a clamping cylinder, and a driving bar 104. The reciprocating groove block 101 is laterally slidably connected to the side plate 42 through a sliding block 105, and is driven to reciprocate by a group of screw rods 106 threadedly connected in the sliding block 105. The screw rods 106 are rotatably connected to the left guide 43 or the right guide 44, and are driven to rotate by a screw motor. Multiple groups of alignment grooves 107 are opened on the opposite sides of the two groups of reciprocating groove blocks 101. A driving block 108 is slidably connected in the alignment groove 107. A support body 109 that is flush with the raised base in the middle extends outward from the bottom side of the groove. The clamping blocks 102 are connected to the driving blocks 108 in a one-to-one correspondence. The bottom side of the clamping blocks 102 is relatively matched with the support body 109 to clamp the carrier 10 located therein, and the carrier 10 is driven forward under the drive of the screw rod 106. An inclined The sliding surface 110 and the reciprocating groove block 101 are fixed with multiple groups of guide rods 111 guided and connected in the driving bar 104 and a driving motor that drives the driving bar 104 to move along the guide rod 111 through the screw 112. The screw 112 is threadedly connected in the driving bar 104, and one end of the screw 112 is rotatably connected in the reciprocating groove block 101 and is connected to the driving motor. The bottom side of the driving bar 104 is also provided with an inclined sliding surface 2 that slidably cooperates with the inclined sliding surface 110. The movement direction of the driving bar 104 along the guide rod 111 is perpendicular to the movement direction of the clamping block 102. When the driving motor drives the screw 112 to rotate, the driving bar 104 can be driven to move along the guide rod 111, and then the clamping block 102 can be driven to move in the direction perpendicular to the guide rod 111 through the sliding cooperation of the inclined sliding surface 110 and the inclined sliding surface 2, so as to cooperate with the support body 109 to limit the carrier 10.

[0047] The locking rod 8 includes a positioning pressure rod 81 and a locking screw rod 82. The top of the positioning pressure rod 81 is provided with an adapter block connected to the locking screw rod 82. The locking screw rod 82 is provided with an external thread that is threadedly connected to the middle raised base of the carrier support plate 2.

[0048] The cutting knife 5 includes a knife rod 51, a connecting block 52, a knife body, and a screw rod 53. Two sets of screw rods 53 are rotatably connected to the tail ends of the left guide 43 and the right guide 44, and one end of each set of screw rods 53 is connected to a screw motor drive. The connecting blocks 52 connected to both ends of the knife rod 51 are threadedly connected to the outside of the screw rod 53, and the screw rod 53 drives the knife rod 51 and the knife body on the knife rod 51 to rise and fall. The knife body passes through the left guide 43 and the right guide 44 to cut the carrier tape 10 in the guide slot 45.

[0049] A limiting groove 21 is further provided at one end of the carrier support plate 2 for positioning the first section of the carrier 10, and limiting blocks 22 are slidably connected in two groups of limiting grooves 21 distributed symmetrically. The limiting blocks 22 include auxiliary supporting blocks 221 connected to both sides of the central raised base and limiting plates 222 used for limiting on both sides of the carrier 10. Before the first section of the carrier 10 is positioned, the limiting blocks 22 can be inserted into the limiting grooves 21, so that the carrier 10 can be quickly limited to the middle position of the carrier support plate 2, and then the first section of the carrier 10 can be locked by using the locking rod 8, and then the limiting blocks 22 can be taken out to wait for the carrier support plate 2 to be replaced, and when this carrier support plate 2 is aligned with the guide groove 4, it is only necessary to manually support the first section of the carrier 10 to enter the guide groove 4 when introducing the carrier support plate 2, and the subsequent operation is carried out by the carrier support plate 2, which is more convenient.

[0050] Example 2

[0051] like Figures 7-8 As shown, a cutting device for an inductor protective carrier 10 is provided. In this embodiment, a push column 113 is further provided on the bottom side of the clamping block 102. The push column 113 is used to be inserted into the push holes on both sides of the carrier 10 for inserting and positioning the carrier 10 so that the carrier 10 can be clamped and driven forward more stably.

[0052] Example 3

[0053] like Figure 9As shown, a cutting device for an inductor protective carrier tape 10 is provided. In this embodiment, a protective sleeve 114 surrounding the outside of the push column 113 is further provided on the bottom side of the clamp block 102. The top end of the protective sleeve 114 is limited in the protective card slot of the clamp block 102, and the protective sleeve 114 is pressed against the outside of the push column 113 by a pressing spring 115 placed in the protective card slot. Therefore, when the clamp block 102 presses the carrier tape 10, the protective sleeve 114 can be indirectly used to elastically press the carrier tape 10, and the protective sleeve 114 is The propulsion column 113 can extend out of the protective sleeve 114 and be positioned in the propulsion hole of the carrier 10. At the same time, when the clamp 102 releases the carrier 10, the protective sleeve 114 can also serve as a structure to block the carrier 10, preventing the carrier 10 from getting stuck in the propulsion column 113 and rising with the propulsion column 113, thereby affecting the retreat of the automatic pushing structure 100. That is, if the propulsion column 113 is stuck in the propulsion hole, the propulsion column 113 rises, and the carrier 10 can be separated from the propulsion column 113 under the pressure of the protective sleeve 114 and the pressure spring 115.

[0054] The working principle of the present invention is as follows: when in use, after the alignment holes of the carrier support plate 2 and the guide groove 4 are aligned and locked, the distance between the cutting knife 5 and the first section of the carrier 10 is known, and the carrier 10 is continuously pulled forward, so that the carrier 10 on the right side of the cutting knife 5 has reached the standard length of the fixed-length carrier 10, and the cutting knife 5 can be driven to cut the carrier 10, and the subsequent carrier 10 can be driven once according to the fixed-length, and the cutting action is continued until the fixed-length cutting of a roll of carrier 10 is completed, and then by replacing the carrier aligned with the guide groove 4 The belt support plate 2 is used to realize the rapid replacement of the new and old carrier racks 7. During the replacement, since the new carrier rack 7 is installed when the old carrier rack 7 is cutting the carrier tape 10, the time for replacing the carrier rack 7 can be saved, and the overall processing efficiency can be improved. During the replacement, only the carrier support plate 2 that has completed the transmission of the carrier tape 10 needs to be pulled out of the guide groove 4, and then the slide 1 is slid to align the new carrier support plate 2 with the guide groove 4, and then the carrier support plate 2 is driven to slide into the guide groove 4, so as to complete the guidance of the first section of the carrier tape 10, which is more convenient and has better reliability and stability.

[0055] The two groups of carrier support plates 2 arranged on the roll-changing slide 1 are used to alternately dock with one end of the guide groove 4 of the guide cutting section, so that when one group of carrier support plates 2 positions one end of the carrier 10 and stretches the carrier 10 to slide into the guide groove 4 for positioning, the other group of carrier support plates 2 can be manually operated to position one end of the new unrolled carrier 10, and wait for the previous roll of carrier 10 to be cut, and then directly perform position alternation, thereby saving the waiting time for roll changing, and the carrier support plates 2 drive the carrier 10 through the guide groove 4, which is more convenient than manually limiting the carrier 10 in the longer guide groove 4, and the stability is also better;

[0056] An automatic material pushing structure 100 can be arranged in the middle of the guiding groove 4. The automatic material pushing structure 100 is used to drive the carrier tape 10 to advance at a fixed length, and assist the cutting knife 5 on the guiding groove 4 to achieve automatic cutting once after each advancement, so as to achieve an automatic cutting effect and better cutting stability;

[0057] The automatic material pushing structure 100 advances by clamping the carrier tape 10 side by side with multiple groups of clamping blocks 102. Compared with only driving a group of clamping blocks 102 to clamp the carrier tape 10 by a group of clamping cylinders, the stability is better. Because the setting of multiple groups of clamping blocks 102 can disperse the driving force for driving the carrier tape 10 to advance, and drive in multi-point cooperation, which can reduce the probability of tensile fracture when driving forward with a single point of force. Moreover, the clamping force of multiple groups of clamping blocks 102 is driven by a long strip-shaped driving bar 104 to clamp, and the movement mode of the driving bar 104 is perpendicular to the direction of the clamping force. Therefore, only driving the driving bar 104 to move by a group of clamping cylinders to provide clamping force for the clamping blocks 102 will not cause the driving force to decrease sequentially from the clamping end of the clamping cylinder to both sides, and can ensure that each group of clamping blocks 102 can have an average and stable clamping force, so as to improve the stability of the carrier tape 10 advancing and avoid the risk of the carrier tape 10 breaking during advancement;

[0058] The clamping block 102 is provided with a pushing column 113 for positioning in the advancing hole of the carrier tape 10, so as to ensure the length of the carrier tape 10 advancing at a fixed length, and further prevent the phenomenon of uneven cutting length caused by the carrier tape 10 slipping during advancement. Moreover, the cooperation of the structure in this way with the structures of the clamping block 102 and the driving bar 104 can also avoid different lateral pushing forces acting on different advancing holes when the pushing column 113 is inserted into the advancing hole, resulting in the tearing and breaking of the advancing hole with excessive force. That is, the uniformity effect of the clamping force can balance the forces of multiple groups of advancing holes when the carrier tape 10 shows a tendency to slip and the advancing hole is laterally stressed, so as to reduce the risk of the carrier tape 10 being torn and broken;

[0059] The carrier tape support plate 2 can be manually pushed to slide into or out of the guiding groove 4, or can be driven by an electric push cylinder to achieve automatic sliding in or out. When manually sliding in or out, the positioning column 9 can be inserted between one end of the guiding groove 4 and the guiding support plate for auxiliary positioning. That is, after the carrier tape support plate 2 slides to a certain position, the alignment holes on the carrier tape support plate 2 and the guiding groove 4 are aligned. At this time, the positioning column 9 is inserted into the two groups of alignment holes, and the carrier tape support plate 2 and the guiding groove 4 can be positioned and fixed.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
