Description

Technical Field

[0002] During the processing of semiconductors and electronic components, it is necessary to package the components through packaging equipment, such as a taping machine, which is an automated device used to install semiconductor chips on a specific tape carrier (usually a plastic reel). The taping machine weaves the chip into the carrier tape through precise position alignment and fixation. When the taping machine is in use, the carrier tape needs to be manually inserted into the conveying device of the taping machine first, and the carrier tape moves to the specified position through the conveying channel of the conveying device, and then the needle wheel engages with the carrier tape, so that the needle wheel drives the carrier tape to move, and the chip is placed in the acupuncture point of the carrier tape, and then the carrier tape is sealed with a cover tape, and the sealed carrier tape is reeled up by the reeling assembly. The existing carrier tape conveying channel is roughly U-shaped. Due to the long conveying channel and the existence of a curved channel, there is a large resistance when manually threading and using the tape, which is easy to get stuck and cause the needle wheel to separate from the carrier tape.

DETAILED DESCRIPTION

[0064] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0065] In this embodiment, "several" and "multiple" refer to two or more. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0066] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] This embodiment relates to a conveying device and a tape braiding machine. The carrier tape is a carrier for storing electronic components such as chips, usually in a strip shape. The materials received by the tape braiding machine are placed in the carrier tape and stored by the carrier tape. The carrier tape is conveyed along a preset path by the conveying device. The carrier tape is driven by a driving component and moves in a step-by-step manner.

[0068] <Example 1>

[0069] like Figure 1As shown, the conveying device 100 provided in this embodiment includes a conveying channel, which is a channel for the carrier tape 200 to travel. The empty carrier tape enters from one end of the conveying channel and moves in the conveying channel along the X direction. The conveying channel includes a first linear channel 10, a curved channel 30, and a second linear channel 20 connected in sequence. The carrier tape 200 enters from the first linear channel 10, passes through the curved channel 30, and enters the second linear channel 20. The second linear channel 20 is spaced apart from the first linear channel. The carrier tape 200 enters from the feed port 102 of the first linear channel 10 at a lower position, and after entering the second linear channel 20, chips and other materials are placed on the top. The two ends of the curved channel 30 are connected to the first straight channel 10 and the second straight channel 20 respectively. The carrier 200 can be raised through the curved channel 30. The curved channel 30 includes a plurality of arc segments 31 connected in sequence. There are at least two arc segments 31. Adjacent arc segments are tangent to each other to ensure a smooth transition. The curvatures of adjacent arc segments are different. A plurality of arc segments 31 are connected in sequence between the first straight channel 10 and the second straight channel 20 to form a variable curvature curved channel. The carrier has different frictions when passing through the arc segments 31 with different curvatures, thereby affecting the smoothness of the movement of the carrier in the curved channel 30. At the same time, since the carrier needs to be inserted into the conveying channel manually before processing, the curved channel affects the difficulty of inserting the tape. Under the same space constraints, the curved channel formed by splicing a plurality of arc segments 31 with different curvatures can make the carrier move more smoothly in the curved channel, with less resistance and less prone to jamming, compared with the curved channel with the same curvature.

[0070] like Figure 2As shown in the figure, in this embodiment, the first straight channel 10 and the second straight channel 20 are parallel and the distance between them is H. The two straight channels are horizontally arranged. The curved channel 30 is tangent to the lower straight segment 101 and the upper straight segment 201, forming the first tangent point P1 and the second tangent point P2 respectively. The lower straight segment 101 and the upper straight segment 201 are the ends of the first and second straight channels. The outermost vertex D of the curved channel 30, the distance between the second straight segment 20 and the main shaft of the machine is S, and the distance between the second tangent point P2 and the vertex D is L. When L is the same as S, the position of the vertex D is the closest to the main shaft of the machine, and further increase will cause interference with the main shaft of the machine. The distance between the second tangent point P2 and the vertex D is less than the distance between the first tangent point P1 and the vertex S. The outside of the curved channel corresponds to the main shaft of the taping machine. Therefore, its distance D is limited by the space. In addition, the second tangent point P2 is limited by the first straight channel 10. There are multiple components such as sensors, blanking components, and shearing components downstream of the first straight channel 10. If the second tangent point P2 moves away from the main shaft of the machine to the left, the above-mentioned multiple components all need to be adjusted. Therefore, by making the first tangent point P1 farther from the main shaft of the machine than the second tangent point P2, the vertex D of the curved channel is avoided from interfering with the main shaft of the machine. At the same time, it can ensure the smooth movement of the carrier tape in the curved channel. The curved channel of this embodiment includes two arc segments, namely the first arc segment 31a and the second arc segment 31b. The first arc segment 31a is tangent to the second arc segment 31b at the vertex D. The central angle θ1 corresponding to the first arc segment 31a and the central angle θ2 corresponding to the second arc segment 31b are both 90°. The radius R1 of the first arc segment 31a is less than the radius R2 of the second arc segment 31b.

[0071] If only one arc M is used, restricted by the second tangent point P2 and the distance S, the curvature K1 of this arc segment = 1 / R1; if two tangent arcs are used, the average curvature K2 of the curved channel = 1 / 2*(1 / R1 + 1 / R2); Since actually H > 2R1, therefore, R2 > R1, the curvature 1 / R1 of the first arc segment 31a is greater than the curvature 1 / R2 of the second arc segment 31b, so K2 < K1. Therefore, the segmented arc has a lower degree of bending than the single-arc curved channel and has a smaller frictional resistance to the carrier tape.

[0072] <Embodiment 2>

[0073] In this embodiment, the same parts as those in Embodiment 1 are given the same reference numerals and the same textual descriptions are omitted.

[0074] As Figure 3 shown, compared with Embodiment 1, the difference in the conveying device provided in this embodiment is that the curved channel 30 is connected by three arcs:

[0075] The curved channel 30 of this embodiment includes a first arc segment 31a, a second arc segment 31b and a third arc segment 31c. The first arc segment 31a corresponds to a central angle of θ1. The first arc segment 31a is tangent to the upper straight segment 201 and the second arc segment 31b respectively. The third arc segment 31c is tangent to the second arc segment 31b and the lower straight segment 101 respectively. The second arc segment 31b corresponds to a central angle of θ2, and the third arc segment 31c corresponds to a central angle of θ3. θ2>θ3>θ1, and R1, R2, and R3 are adjusted according to the machine space and the size of the carrier resistance. In this embodiment, R1<R3<R2, the curvature of the first arc segment 31a is greater than that of the third arc segment 31c, and the curvature of the third arc segment 31c is greater than that of the second arc segment 31b. The first arc segment 31a makes a smooth transition to reduce the initial friction. When the carrier is in the second arc segment 31b, the normal force decreases and the friction decreases, wherein θ2 and R2 are relatively large, and the moving path of the carrier in the second arc segment 31b is relatively long. By reasonably allocating the radii of the three arcs and the corresponding central angles, the overall friction can be significantly reduced while satisfying the geometric constraints, making the carrier move more smoothly.

[0076] <Example 3>

[0077] In this embodiment, the same parts as those in Embodiments 1 and 2 are given the same figure marks, and the same text descriptions are omitted.

[0078] like Figure 1 , Figures 4 to 9As shown, relative to the first and second embodiments, this embodiment provides a conveying device, including a track assembly, and a conveying channel is arranged in the track assembly. The track assembly includes a first straight track assembly 110, a second straight track assembly 120, and a curved track assembly 130 connected to the first and second straight track assemblies, respectively, and the first and second straight track assemblies are arranged in parallel. An upper guide slope 122 and a lower guide slope 123 are arranged between the curved track assembly 130 and the second straight track assembly 120, and the upper guide slope 122 guides the carrier tape 200 from top to bottom to enter the second straight track assembly, and the lower guide slope 123 guides the carrier tape 200 from bottom to top to enter the second straight track assembly 120. When the carrier belt 200 passes through the curved track assembly 130 and enters the second straight track assembly 120, the carrier belt bends in the curved track assembly 130. When the carrier belt passes through the intersection of the curved track assembly 130 and the second straight track assembly 120, the end of the carrier belt will be lifted up and easily get stuck at the joint position. Through the upper and lower guide slopes, the carrier belt is first guided by the upper guide slope to move toward the second straight track assembly 120, and then the carrier belt is guided by the lower guide slope to enter the second straight channel, and the upper guide slope is located upstream of the lower guide slope. Through the above technical means, the carrier belt can be more smoothly switched when switching tracks to avoid getting stuck when threading. The curved channel 30 is arranged in the curved track assembly 130, and the curved track assembly 130 includes a curved track 131, and the curved track 131 has an upper connecting portion 132 and a lower connecting portion 133. The curved channel 30 is located between the upper connecting portion 132 and the lower connecting portion 133. The upper connecting portion 132 corresponds to the upper straight segment 201, and the lower connecting portion 133 corresponds to the lower straight segment 101, that is, the upper and lower connecting portions are both arranged straight, and the curved track 131 is curved between the upper and lower connecting portions. Through the upper and lower connecting portions, it is easy to assemble the curved track assembly with the first and second straight track assemblies. After passing through the first straight track assembly 110, the carrier tape enters the curved channel of the curved track assembly through the lower connecting portion 133, and then enters the second straight track assembly through the upper connecting portion 132.

[0079] Furthermore, the curved track assembly 130 includes a curved track sealing tape 134 disposed on the curved track 131 to close the curved track 131. The curved track sealing tape 134 is arc-shaped and has a certain elasticity and can be made of metal material. The curved track sealing tape 134 is attached to the curved track 131 and is locked by screws. The curved track 131 and the curved track sealing tape 134 are respectively an integral part, that is, they are not spliced ​​together and can be formed by 3D printing to avoid seams and further improve the smoothness of the movement of the carrier tape. The curved track 131 also has a track groove 135, and bearing surfaces 136 are provided on both sides of the track groove 135. Both sides of the carrier tape 20 are supported by the bearing surfaces 136 and move in the track groove 135. An outlet portion 137 is provided between the upper connecting portion 132 and the curved track sealing tape 134, and the carrier tape can be exported through the outlet portion 137. The second straight rail assembly 120 is provided with an inlet portion 121 corresponding to the outlet portion 137, and the carrier tape guided out of the outlet portion 137 enters the inlet portion 121, and thus enters the second straight rail assembly 120. An upper guide slope 122 and a lower guide slope 123 are provided between the outlet portion 137 and the inlet portion 121. The upper guide slope 122 is inclined from top to bottom toward the inlet portion 121, and the lower guide slope 123 is inclined from bottom to top toward the inlet portion 121. The lower guide slope 123 is located downstream of the upper guide slope 122, and the upstream and downstream are divided by the front and rear of the carrier tape moving path. The upper guide slope 122 extends to the upper part of the upper connecting portion 132. The end of the curved rail sealing tape 134 abuts against the upper guide slope 122, and the upper connecting portion 132 abuts against the lower guide slope 123, so that the bearing surface 136 corresponds to the lower guide slope 123. Through the above technical solution, after the carrier tape 20 passes through the curved channel, it is first guided by the upper guide bevel 122 at the exit 137, and the end of the carrier tape 20 will not be stuck. Then the carrier tape on the bearing surface 136 contacts the lower guide bevel 123, so that it can smoothly enter the second straight rail assembly. By setting the upper and lower guide bevels, the carrier tape can be prevented from getting stuck. Specifically, the second straight rail assembly 120 includes a second straight rail 124, and a front cover plate 126 arranged above the second straight rail 124, the upper guide bevel 122 is located below the front cover plate 126, and the front cover plate 126 is used to close the connection between the second straight rail 124 and the curved rail, and the lower guide bevel 123 is located at the end of the second straight rail 124, which is convenient for the processing and installation of the upper and lower guide bevels. The width of the outlet portion 137 is smaller than the width of the inlet portion 121, and the inlet portion 121 is in a trumpet shape. The width of the junction between the outlet portion 137 and the inlet portion 121 is smaller than the width of the inlet portion 121, so that when the carrier tape enters the inlet portion 121, the two sides will not be stuck. In the above technical solution, the carrier tape can smoothly pass through the junction between the curved track assembly and the second straight track assembly by guiding in four directions of up, down, left and right between the outlet portion and the inlet portion.

[0080] like Figures 9 to 13As shown, further, an adjustment component 140 is provided between the second straight rail component 120 and the curved rail component 130 to adjust the relative position of the curved rail 131 and the second straight rail 124, so that the curved rail 131 and the second straight rail 124 can be adjusted during assembly, so that the inlet portion 121 and the outlet portion 137 are aligned to avoid jamming when the carrier tape passes through. The existing conveying device cannot adjust the connection position of the curved rail component and the second straight rail component. During installation, if the joint height is uneven, it will jam when the carrier tape is passed, and the carrier tape cannot pass. It is necessary to disassemble the connection mechanism of the two components and readjust the position, which consumes a lot of man-hours. In this embodiment, the end of the curved rail 131 is set on the connection platform 1241 of the second straight rail 124, and the upper part of the curved rail 131 is pressed by the front cover plate 126, and the front cover plate 126 and the curved rail 131 are locked by screws, so as to achieve locking in the up and down directions, and facilitate the assembly and disassembly of the curved rail 131 and the second straight rail 124. The adjustment assembly 140 is arranged on the side of the curved track 131, and the left and right directions of the curved track are adjusted and locked by the adjustment assembly 140. Specifically, the adjustment assembly 140 includes a first adjustment member 141, a second adjustment member 142, a locking member 143 and a mounting block 144. The locking member 143 is arranged through the mounting block 144 and is detachably connected to the second straight rail 124. The mounting block 144 can be locked or released by the locking member 143. The first adjustment member 141 passes through the mounting block 144 and is detachably connected to the curved track 131. The first adjustment member 141 drives the curved track 131 to move outward along the first direction Y, thereby moving the curved track 131 outward. The second adjustment member 142 passes through the mounting block 144 and one end corresponds to the second straight rail 124. When the end of the second adjustment member 142 abuts against the second straight rail 124, the second adjustment member 142 continues to be driven, so that the second adjustment member 142 pushes the curved track 131 to move inward along the first direction Y. Specifically, the first adjusting member 141 and the locking member 143 are both screws, which are threadedly connected to the screw holes of the curved rail and the second straight rail, and the second adjusting member 142 is a top screw, which is threadedly connected to the mounting block 144. The first adjusting member 141 passes through the mounting block 144 and is locked into the curved rail 131. The first adjusting member 141 is limited by the mounting block, and the locking member 143 passes through the mounting block 144 and is locked into the second straight rail 124. When the position of the curved rail needs to be adjusted, the first adjusting member 141 is first rotated, and the first adjusting member 141 can drive the curved rail 131 to move outward through the threaded connection. When the curved rail 131 needs to be adjusted inward, the first adjusting member 141 needs to be rotated in the opposite direction first, so that the first adjusting member 141 is withdrawn from the screw hole of the curved rail for a distance to provide an adjustment distance; then the second adjusting member 142 is rotated to push the curved rail 131 to move inward. By rotating the first and second adjusting members, the horizontal position of the curved rail can be adjusted so that it is aligned with the second straight rail 124.

[0081] Furthermore, the mounting block 144 is provided with a groove 1441 for the first adjusting member 141 to pass through, and the first adjusting member 141 is arranged in the groove 1441 of the mounting block 144. When the first adjusting member 141 is locked, the mounting block 144 is pressed against, and when the first adjusting member 141 is released, the first adjusting member 141 can be separated from the mounting block 144. The mounting block 144 is located at the assembly position T of the curved rail 131 and the second straight rail 124, that is, when the adjustment assembly is adjusted into place, the mounting block 144 blocks the assembly position T, and when the first adjusting member 141, the second adjusting member 142 and the locking member 143 are released, the first adjusting member 141 no longer presses the mounting block 144, and the mounting block 144 rotates downward around the first locking member 141 until it is offset from the curved rail 131, as shown in FIG. Fig.10 As shown by the middle arrow, due to the gravity of the mounting block 144, it can rotate clockwise, thereby opening the assembly position T, so that the curved track assembly can be taken out along the outside of the first direction Y without moving along the second direction X. Since the machine spindle of the braiding machine is arranged on the outside of the curved track assembly in the second direction X, in order to make the structure of the whole machine compact, the space in the second direction is small, and it is difficult to move and disassemble the curved track assembly along the second direction, which is not easy to operate. Through the above technical solution, the curved track assembly can be separated or assembled from the second straight track assembly along the first direction Y, which improves the convenience of operation; and solves the problem that the traditional equipment needs to move along the track direction when disassembling and assembling the curved track due to the small space, which is extremely inconvenient to operate.

[0082] like Figure 5 and Figure 7 As shown, further, the first straight rail assembly 110 includes a front guide 111, and a pressure head assembly 112 arranged above the front guide 111, the pressure head assembly 112 presses or releases the front guide 111, one end of the front guide 111 is provided with the feed port 102, and the other end is connected to the curved rail assembly 130. Since the front guide 111 is suspended, the front guide 111 can be pressed by the pressure head assembly 112 to make it more stable. The pressing assembly 112 includes a pressure head 1121 and a pressure head seat 1122, the pressure head 1121 is threadedly connected to the pressure head seat 1122, the pressure head 1121 faces the front guide 111, and the front guide 111 is pressed or released by rotating the pressure head 1121. An adapter seat 113 and an upper cover 114 are provided between the front guide 111 and the curved track 131 . The adapter seat 113 is provided with a bell mouth 1131 . The carrier tape enters the curved track 131 through the bell mouth 1131 , so that the carrier tape can smoothly pass through the adapter seat 113 . The upper cover 114 is used to close the adapter seat 113 .

[0083] like Fig.12 and Fig.13As shown, further, the second straight rail assembly 120 includes a front cover plate 126 disposed on the second straight rail 124, used to shield the second straight channel 20, and a sensor assembly 127. The front cover plate 126 is provided with a feed port 1261, and the feed port 1261 is connected to the second straight channel 20. After the carrier tape passes through the second straight channel 20, the material channel feed port 1261 falls into the acupuncture point of the carrier tape. The sensor assembly 127 detects the material at the feed port 1261. The sensor assembly 127 includes a beam optical fiber sensor 1271 disposed on a sensor seat 1272. The detection range of the beam optical fiber sensor 1271 covers the feed port 1261. When the material reaches above the feed port 1261, the beam optical fiber sensor 1271 senses the material. The second straight rail 124 is provided with a pressing block 128 and a rear cover plate 129. The rear cover plate 129 is arranged between the pressing block 128 and the front cover plate 126. A cover tape inlet 1280 is provided between the rear cover plate 129 and the pressing block 12. The cover tape 300 is introduced through the cover tape inlet 1280. The cover tape is used to cover the carrier tape 200 and seal the carrier tape 200.

[0084] like Figures 14 to 17 As shown, further, the second straight rail 124 is installed on the partition 103 and connected to the integrated gas circuit assembly 150, the integrated gas circuit assembly 150 provides vacuum negative pressure, and the partition 103 is installed on the base through the fixed block 104. The integrated gas circuit assembly 150 includes a vacuum generator 151, an adapter 152 and a gas distribution joint 153 that are connected in sequence, and the above components are connected through a conduit to form an air circuit. The vacuum generator 151 is arranged on the first side 1031 of the partition 103 and can generate negative pressure. The adapter 152 has a plurality of joints 1521. In this embodiment, four joints are provided. The joints 1521 are respectively connected to the vacuum generator 151 so that the negative pressure is transmitted to the adapter 152. The adapter 152 is arranged on the partition 103 and passes through the partition, so that the joints 1521 are distributed on both sides of the partition so that the negative pressure can pass through the partition. The air distribution joint 153 is arranged on the second side 1032 of the partition 103, and the first side 1031 and the second side 1032 are arranged opposite to each other. The first connection port 1531 of the air distribution joint 153 is connected to the joint 1521, and a plurality of second connection ports 1532 are connected to the air joint 154 on the second straight rail 124. The number of second connection ports 1532 can be set as needed. Through the integrated air circuit assembly 150, negative pressure can be formed in the second straight rail 124, so that the materials in the carrier can be adsorbed in the carrier. Through the above technical solution, the negative pressure air circuit can be integrated on both sides of the partition, which is convenient for air circuit connection and arrangement. Fig.16 and Fig.17As shown, a cutting assembly 160 is provided downstream of the second straight rail assembly 120 for cutting the packaged carrier tape. After the carrier tape is packaged, it moves along the second straight rail 124. When it moves to the position of the cutting assembly 160, it is cut by the cutting assembly. The empty carrier tape can be cut off by the cutting assembly 160, or when the rear receiving assembly is full, the carrier tape needs to be cut to replace the new material tray for receiving. Specifically, the cutting assembly 160 includes a pneumatic scissor 161 and a mounting seat 162. The pneumatic scissor 161 is located in the moving path of the carrier tape 200 so that the carrier tape can be cut when passing through. The pneumatic scissor 161 includes a first cutting portion 1611 and a second cutting portion 1612. When the carrier tape passes between the first and second cutting portions, the first and second cutting portions are driven by a cylinder for cutting. The first and second cutting portions are provided with protective sheet metal 163 to protect the cutting portion. The mounting seat 162 is adjustable and connected to the partition 103 to facilitate the adjustment and installation of the mounting seat 162. Specifically, the mounting seat 162 and the partition 103 are respectively provided with a number of mounting holes 1621 and strip holes 1033. In this embodiment, the mounting seat 162 is provided with four mounting holes 1621, and the partition is provided with corresponding four strip holes 1033. The mounting seat 162 can be adjusted in the direction of the strip holes. The extension direction of the strip holes is consistent with the moving direction of the carrier tape in the second straight rail 124, so that the front and rear positions of the pneumatic scissors are adjustable, and the number of strip holes can be changed according to the weight of the pneumatic scissors and other conditions. The mounting holes 1621 correspond to the strip holes 1033. After the pneumatic scissors are adjusted into place, they are locked by the bolt assembly to achieve an adjustable connection. Other adjustable connection methods such as sliding connection can also be used. Since the acupuncture point spacing and size of different carrier tapes are different, their cutting positions will change. Through the above technical solution, the mounting seat 162 can be adjusted in position according to different carrier tape models to change the cutting position of the pneumatic scissors.

[0085] like Fig.14 , Fig.15 , Fig.18 and Fig.19As shown, further, the carrier tape 200 is driven by the driving assembly 170 so that the carrier tape 200 can move in the conveying channel, and the driving assembly 170 is arranged on the partition 103. The driving assembly 170 includes a servo motor 171, a transmission assembly 172 and a pin wheel 173. The servo motor 171 provides power, and the servo motor 171 drives the pin wheel 173 through the transmission assembly 172. The convex point on the pin wheel 173 engages with the carrier tape, so that the carrier tape is driven to move by the rotation of the pin wheel 173. The servo motor 171 is located downstream of the pin wheel 173, that is, the servo motor 171 and the pin wheel 173 are arranged at a certain distance, the pin wheel 173 is close to the inlet 121 of the second straight rail 124, and the servo motor 171 is far away from the inlet 121. The transmission assembly 172 includes a reducer 1721 connected to the pinwheel 173. The reducer 1721 is connected to the pinwheel 173. After this embodiment, the rotating axes of the reducer 1721 and the pinwheel 173 are coaxial, and the reducer drives the pinwheel to rotate. By adopting the reducer 1721, the rotation accuracy of the pinwheel can be greatly improved. For example, if the speed ratio of the reducer is 30, the driving accuracy of the pinwheel can also be improved by 30 times, which is suitable for products with higher precision requirements. A stroke adjustment assembly 174 is provided below the reducer 1721 to adjust the height of the reducer 1721 and the pinwheel 173 so that the distance between the pinwheel 173 and the carrier 200 can be adjusted to make the engagement more stable. Specifically, the stroke adjustment assembly 174 includes a stroke adjustment block 1741 and a stroke adjustment member 1742. The stroke adjustment member 1742 is threadedly connected to the stroke adjustment block 1741 and one end of the stroke adjustment member 1742 is against the reducer 1721. The stroke adjustment member 1742 is rotated to push the reducer 1721 to move. The stroke adjustment member 1742 can be an adjustment member with a threaded portion such as a screw. The transmission assembly 172 includes a synchronous wheel mechanism. The reducer 1721 and the servo motor 171 are connected through the synchronous wheel mechanism. The power of the servo motor is transmitted to the reducer through the synchronous wheel mechanism. The synchronous wheel mechanism includes a driving wheel 1722 and a driven wheel 1723. The driving wheel 1722 is arranged on the servo motor, and the driven wheel 1723 is arranged on the reducer. The driving and driven wheels are connected by a synchronous belt 1724. The pin wheel 173 is connected to the mesh handle 176 through the connecting shaft 175. The pin wheel 173 can be manually rotated through the mesh handle 176, and the carrier tape can be manually retracted, which is convenient for manual intervention when the packaging is abnormal. The reducer 1721 and the servo motor 171 are respectively disposed in the first receiving hole 1034 and the second receiving hole 1035 of the partition, and the first and second receiving holes are located below the second straight rail and are spaced apart.

[0086] like Figures 20 to 22As shown, as an improvement, this embodiment provides another implementation method of the drive assembly. The same parts as the above embodiment are given the same figure marks, and the same text descriptions are omitted. The difference from the above drive assembly is that this embodiment adopts a direct drive method. Specifically, the drive assembly 170 includes a servo motor 171 and a pin wheel 173. The servo motor 171 is connected to the pin wheel 173 and is coaxially arranged. The pin wheel 173 is directly driven by the servo motor 171. This driving method is direct drive, with a simple structure and reduced equipment space occupation. The driving accuracy of the pin wheel 173 depends on the accuracy of the servo motor, which is suitable for products with slightly lower accuracy. A stroke adjustment assembly 174 is provided below the pin wheel 173. The drive assembly 170 is arranged in the second accommodating hole 1035 of the partition 103. The partition 103 can adapt to two drive assemblies, so that the configuration of the drive assembly can be adjusted according to product requirements.

A first detection component 410 and a second detection component 420 are arranged above the conveying device 100. The first detection component 410 detects the incoming material. When the material enters the carrier tape of the second straight rail component 120, the first detection component 410 detects the appearance quality of the material. Then the carrier tape continues to move backward, and the carrier tape and the cover tape are plastic-sealed by the hot pressing plastic sealing component 440. The cover tape is discharged by the cover tape unloading component 460. After plastic sealing, the packaged material is detected by the second detection component 420 to detect whether the plastic-sealed material is abnormal and whether the plastic sealing trace meets the requirements. The first and second detection components are both existing visual inspection devices. The packaged carrier tape is rolled up by the receiving component 450 for easy storage. The cutting assembly 160 is arranged downstream of the hot pressing and molding assembly 440. When the carrier tape needs to be cut, it is cut by the cutting assembly 160.
