Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor device packaging, and particularly to a conveying device, a packaging device and a method. Background Art

[0002] In the processing of semiconductors and electronic components, it is necessary to package the components through a packaging device, such as a taping machine, which is an automated device for mounting semiconductor chips on a specific tape carrier (usually a plastic tape). The taping machine inserts the chips into the tape through precise position alignment and fixation. When the taping machine is in use, the tape needs to be manually inserted into the conveying device of the taping machine first. The tape moves through the conveying channel of the conveying device to a designated position, and then meshes with the tape through a pinwheel to drive the tape to move. The chip is placed in the cavity of the tape, and then the tape is sealed with a cover tape, and the sealed tape is wound by a winding assembly. The existing conveying channel of the tape is generally U-shaped. Due to the long conveying channel and the existence of a curved channel, the manual threading and the resistance during use are large, which is easy to get stuck and cause the pinwheel to disengage from the tape.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

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

[0068] <Example 1>

[0069] As 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 along the X direction within the conveying channel. The conveying channel includes a first straight channel 10, a bending channel 30, and a second straight channel 20 that are connected in sequence. The carrier tape 200 enters from the first straight channel 10, passes through the bending channel 30, and then enters the second straight channel 20. The second straight channel 20 is arranged at an interval from the first straight channel. The carrier tape 200 enters from the feed port 102 of the first straight channel 10 at a lower position, and after entering the second straight channel 20, components such as chips are placed above it. Both ends of the bending channel 30 are respectively connected to the first straight channel 10 and the second straight channel 20. Through the bending channel 30, the carrier tape 200 can be lifted. The bending channel 30 includes a number of arc segments 31 connected in sequence. There are at least two arc segments 31, and adjacent arc segments are tangent to ensure smooth transition. The curvatures of adjacent arc segments are different. A number 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 bending channel. The carrier tape has different frictions when passing through arc segments 31 with different curvatures, which affects the smoothness of the movement of the carrier tape in the bending channel 30. At the same time, since the carrier tape needs to be threaded into the conveying channel manually or by other means before starting processing, the bending channel affects the difficulty of threading. Under the same space limitation, the bending channel formed by splicing a number of arc segments 31 with different curvatures can make the carrier tape move more smoothly in the bending channel, with less resistance and less prone to jamming compared to a bending channel with the same curvature.

[0070] As 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 table 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 table, and any further increase will cause interference with the main shaft of the machine table. 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 D. The outer side 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 second straight channel 20. There are multiple components such as sensors, blanking components, and shearing components downstream of the second straight channel 20. If the second tangent point P2 moves away from the main shaft of the machine table to the left, the above-mentioned multiple components all need to be adjusted. Therefore, by making the first tangent point P1 farther away from the main shaft of the machine table than the second tangent point P2, the vertex D of the curved channel is avoided from interfering with the main shaft of the machine table. 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 lies in that the curved channel 30 is connected by three arcs:

[0075] The bending channel 30 of this embodiment includes a first arc segment 31a, a second arc segment 31b, and a third arc segment 31c. The central angle corresponding to the first arc segment 31a is 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 central angle corresponding to the second arc segment 31b is θ2, and the central angle corresponding to the third arc segment 31c is θ3. θ2 > θ3 > θ1, and R1, R2, and R3 are adjusted according to the machine space and the magnitude of the carrier tape 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 initial friction is reduced through the smooth transition of the first arc segment 31a. When the carrier tape is in the second arc segment 31b, the normal force decreases and the frictional force decreases. Among them, θ2 and R2 are relatively large, and the moving path of the carrier tape in the second arc segment 31b is relatively long. By reasonably distributing the radii of the three arc segments and the corresponding central angle angles, the overall frictional force can be significantly reduced on the premise of meeting the geometric constraints, making the movement of the carrier tape smoother.

[0076] <Embodiment III>

[0077] In this embodiment, the parts that are the same as those in Embodiment 1 and Embodiment 2 are given the same reference numerals, and the same text descriptions are omitted.

[0078] As 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] Further, the curved rail assembly 130 includes a curved rail sealing strip 134 disposed on the curved rail 131 to enclose the curved rail 131. The curved rail sealing strip 134 is arc-shaped and has a certain elasticity. It can be made of a metal material. The curved rail sealing strip 134 is attached to the curved rail 131 and locked by screws. The curved rail 131 and the curved rail sealing strip 134 are respectively one-piece, that is, not formed by splicing, and can be made by 3D printing to avoid seams, further improving the smooth movement of the carrier tape. The curved rail 131 also has a rail groove 135, and bearing surfaces 136 are provided on both sides of the rail groove 135. Both sides of the carrier tape 20 are supported by the bearing surfaces 136 and move within the rail groove 135. An outlet portion 137 is provided between the upper connecting portion 132 and the curved rail sealing strip 134, and the carrier tape can be led out through the outlet portion 137. The second straight rail assembly 120 is provided with an inlet portion 121 corresponding to the outlet portion 137. The carrier tape led out from the outlet portion 137 enters the inlet portion 121 and thus enters the second straight rail assembly 120. An upper guiding slope 122 and a lower guiding slope 123 are provided between the outlet portion 137 and the inlet portion 121. The upper guiding slope 122 slopes downward in the direction of the inlet portion 121 from top to bottom, and the lower guiding slope 123 slopes upward in the direction of the inlet portion 121 from bottom to top. The lower guiding slope 123 is located downstream of the upper guiding slope 122. The upstream and downstream are divided according to the front and back of the carrier tape movement path. The upper guiding slope 122 extends above the upper connecting portion 132. The end of the curved rail sealing strip 134 abuts against the upper guiding slope 122, and the upper connecting portion 132 abuts against the lower guiding slope 123, so that the bearing surface 136 corresponds to the lower guiding slope 123. Through the above technical solution, after the carrier tape 20 passes through the bending channel, it is first guided by the upper guiding slope 122 at the position of the outlet portion 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 guiding slope 123, enabling it to smoothly enter the second straight rail assembly. Through the setting of the upper and lower guiding slopes, 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 disposed above the second straight rail 124. The upper guiding slope 122 is located below the front cover plate 126. The front cover plate 126 is used to enclose the connection between the second straight rail 124 and the curved rail. The lower guiding slope 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 guiding slopes. The width of the outlet portion 137 is smaller than the width of the inlet portion 121. The inlet portion 121 is in a flared shape, and the width at the connection between the outlet portion 137 and the inlet portion 121 is smaller than the width of the inlet portion 121. Thus, when the carrier tape enters the inlet portion 121, both sides will not be stuck. In the above technical solution, by guiding in the four directions of up, down, left, and right between the outlet portion and the inlet portion, the carrier tape can smoothly pass through the connection between the curved rail assembly and the second straight rail assembly.

[0080] Such as Figures 9 to 13As shown in the figure, further, an adjusting assembly 140 is provided between the second straight rail assembly 120 and the curved rail assembly 130 to adjust the relative positions 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 and aligned during assembly, aligning the inlet portion 121 and the outlet portion 137, and preventing the carrier tape from getting stuck when passing through. In the existing conveying device, the connection position between the curved rail assembly and the second straight rail assembly cannot be adjusted. During installation, if the joints are uneven in height, the carrier tape will get stuck when threading, and the carrier tape cannot pass through. It is necessary to disassemble the connection mechanism of the two assemblies and re-align and adjust them, which consumes a lot of man-hours. In this embodiment, the end of the curved rail 131 is arranged on the connection platform 1241 of the second straight rail 124, and the curved rail 131 is pressed by the front cover plate 126 above. The front cover plate 126 and the curved rail 131 are locked by screws, so as to achieve locking in the up and down direction and facilitate the assembly and disassembly of the curved rail 131 and the second straight rail 124. The adjusting assembly 140 is arranged on the side of the curved rail 131, and the left and right directions of the curved rail are adjusted and locked by the adjusting assembly 140. Specifically, the adjusting assembly 140 includes a first adjusting member 141, a second adjusting member 142, a locking member 143 and a mounting block 144. The locking member 143 passes through the mounting block 144 and is detachably connected to the second straight rail 124. The mounting block 144 can be locked or released through the locking member 143. The first adjusting member 141 passes through the mounting block 144 and is detachably connected to the curved rail 131. The first adjusting member 141 drives the curved rail 131 to move outward along the first direction Y, so that the curved rail 131 moves outward. The second adjusting member 142 passes through the mounting block 144 and one end corresponds to the second straight rail 124. When the end of the second adjusting member 142 abuts against the second straight rail 124, the second adjusting member 142 is continuously driven, so that the second adjusting member 142 pushes the curved rail 131 to move inward along the first direction Y. Specifically, both the first adjusting member 141 and the locking member 143 are screws, which are threadedly connected to the screw holes of the curved rail and the second straight rail. The second adjusting member 142 is a set screw, which is threadedly connected to the mounting block 144. After the first adjusting member 141 passes through the mounting block 144, it is locked into the curved rail 131. The first adjusting member 141 is limited by the mounting block. After the locking member 143 passes through the mounting block 144, it is locked into the second straight rail 124. When the position of the curved rail needs to be adjusted, first rotate the first adjusting member 141. Through threaded connection, the first adjusting member 141 can drive the curved rail 131 to move outward. When the curved rail 131 needs to be adjusted inward, it is necessary to first rotate the first adjusting member 141 in the reverse direction to make the first adjusting member 141 withdraw from the screw hole of the curved rail by a certain distance to provide an adjustment distance; then rotate the second adjusting member 142 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. Figure 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 Figure 12 and Figure 13As shown, further, the second straight rail assembly 120 includes a front cover plate 126 disposed on the second straight rail 124 for shielding the second straight channel 20, and a sensor assembly 127. The front cover plate 126 is provided with a feeding port 1261 which communicates with the second straight channel 20. After the carrier tape penetrates into the second straight channel 20, the components in the component channel fall into the cavities of the carrier tape through the feeding port 1261. The sensor assembly 127 detects the components at the feeding port 1261. The sensor assembly 127 includes an opposed fiber optic sensor 1271 disposed on a sensor seat 1272. The detection range of the opposed light sensor 1271 covers the feeding port 1261. When a component reaches above the feeding port 1261, the opposed light sensor 1271 senses the component. A pressing block 128 and a rear cover plate 129 are provided on the second straight rail 124. The rear cover plate 129 is disposed between the pressing block 128 and the front cover plate 126. There is a cover tape inlet 1280 between the rear cover plate 129 and the pressing block 128. The cover tape 300 is introduced through the cover tape inlet 1280. The cover tape is used to cover the carrier tape 200 to seal the carrier tape 200.

[0084] As Figures 14 to 17 shown, further, the second straight rail 124 is installed on the partition plate 103 and connected to the integrated air circuit assembly 150. The integrated air circuit assembly 150 provides vacuum negative pressure. The partition plate 103 is installed on the base through a fixing block 104. The integrated air circuit assembly 150 includes a vacuum generator 151, a adapter 152 and an air distribution joint 153 which are connected in sequence. The above components are connected through conduits to form an air circuit. The vacuum generator 151 is disposed on the first side surface 1031 of the partition plate 103 and can generate negative pressure. The adapter 152 has a plurality of joints 1521. In this embodiment, there are four joints. The joints 1521 are respectively connected to the vacuum generator 151 to transmit the negative pressure to the adapter 152. The adapter 152 is disposed on the partition plate 103 and penetrates through the partition plate, so that the joints 1521 are distributed on both sides of the partition plate, enabling the negative pressure to pass through the partition plate. The air distribution joint 153 is disposed on the second side surface 1032 of the partition plate 103. The first side surface 1031 and the second side surface 1032 are opposite to each other. The first connection port 1531 of the air distribution joint 153 is docked with the joint 1521. A plurality of second connection ports 1532 are connected to the air joints 154 on the second straight rail 124. The number of the second connection ports 1532 can be set as required. Through the integrated air circuit assembly 150, a negative pressure can be formed in the second straight rail 124, so that the components in the carrier tape can be adsorbed in the carrier tape. Through the above technical solution, the negative pressure air circuit can be integrated on both sides of the partition plate, facilitating the connection and arrangement of the air circuit. As Figure 16 and Figure 17As shown, a cutting component 160 is provided downstream of the second straight rail component 120 for cutting the completed 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 component 160, it is cut off by the cutting component. The cutting component 160 can cut off the empty carrier tape, or when the rear material receiving component is full, the carrier tape needs to be cut off to replace a new material tray for material receiving. Specifically, the cutting component 160 includes a pneumatic scissors 161 and a mounting seat 162. The pneumatic scissors 161 is located on the moving path of the carrier tape 200 so that when the carrier tape passes through, it can be cut off. The pneumatic scissors 161 includes a first cutting part 1611 and a second cutting part 1612. When the carrier tape passes between the first and second cutting parts, the first and second cutting parts are driven by a cylinder to perform cutting. A protective sheet metal 163 is provided on the first and second cutting parts to protect the cutting parts. The mounting seat 162 is adjustably connected to the partition plate 103, which is convenient for adjusting and installing the mounting seat 162. Specifically, the mounting seat 162 and the partition plate 103 are respectively provided with a plurality of mounting holes 1621 and strip-shaped holes 1033. In this embodiment, the mounting seat 162 is provided with four mounting holes 1621, and the partition plate is provided with corresponding four strip-shaped holes 1033. The mounting seat 162 can be adjusted in position along the direction of the strip-shaped holes. The extending direction of the strip-shaped 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. The number of strip-shaped holes can be changed according to the weight of the pneumatic scissors and other conditions. The mounting holes 1621 correspond to the strip-shaped holes 1033. After the pneumatic scissors are adjusted in place, they are locked by a bolt assembly, thereby realizing the adjustable connection. Other adjustable connection methods such as sliding connection can also be used. Since the acupoint spacing and dimensions of different carrier tapes are different, the cutting positions will change. Through the above technical solutions, 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] As Figure 14 , Figure 15 , Figure 18 and Figure 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. The driving assembly 170 is arranged on the partition plate 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. The servo motor 171 drives the pin wheel 173 through the transmission assembly 172. The bumps on the pin wheel 173 engage 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 apart. The pin wheel 173 is close to the inlet portion 121 of the second straight rail 124, and the servo motor 171 is far from the inlet portion 121. The transmission assembly 172 includes a speed reducer 1721 connected to the pin wheel 173. The speed reducer 1721 is connected to the pin wheel 173. In this embodiment, the rotation axes of the speed reducer 1721 and the pin wheel 173 are coaxial, and the speed reducer drives the pin wheel to rotate. By adopting the speed reducer 1721, the rotation accuracy of the pin wheel can be greatly improved. For example, if the speed ratio of the speed reducer is 30, the driving accuracy of the pin wheel can also be improved by 30 times, which is suitable for products with high precision requirements. A stroke adjustment assembly 174 is arranged below the speed reducer 1721 to adjust the heights of the speed reducer 1721 and the pin wheel 173 so that the distance between the pin wheel 173 and the carrier tape 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 abuts against the speed reducer 1721. By rotating the stroke adjustment member 1742, it pushes the speed 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 pulley mechanism. The speed reducer 1721 and the servo motor 171 are connected through the synchronous pulley mechanism. The power of the servo motor is transmitted to the speed reducer through the synchronous pulley mechanism. The synchronous pulley mechanism includes a driving pulley 1722 and a driven pulley 1723. The driving pulley 1722 is arranged on the servo motor, and the driven pulley 1723 is arranged on the speed reducer. The driving and driven pulleys are connected by a synchronous belt 1724. The pin wheel 173 is connected to a knurled handle 176 through a connecting shaft 175. The pin wheel 173 can be manually rotated through the knurled handle 176, and the carrier tape can be manually retracted, which is convenient for manual intervention when packaging abnormalities occur. The speed reducer 1721 and the servo motor 171 are respectively arranged in the first receiving hole 1034 and the second receiving hole 1035 of the partition plate. The first and second receiving holes are located below the second straight rail and are arranged at intervals.

[0086] As Figures 20 to 22As shown, as an improvement, this embodiment provides another implementation manner of the driving component. For the parts that are the same as those in the above embodiment, the same reference numerals are given and the same text descriptions are omitted. The difference from the above driving component is that this embodiment adopts a direct drive method. Specifically, the driving component 170' includes a servo motor 171' and a pinwheel 173'. The servo motor 171' is connected to the pinwheel 173' and arranged coaxially. The pinwheel 173' is directly driven by the servo motor 171'. This driving method is a direct drive, with a simple structural form, reducing the space occupied by the equipment. The driving accuracy of the pinwheel 173' depends on the accuracy of the servo motor and is suitable for products with slightly lower accuracy. A stroke adjustment component 174 is provided below the pinwheel 173'. The driving component 170' is arranged in the second accommodation hole 1035 of the partition plate 103. The partition plate 103 can accommodate two driving components, so that the configuration of the driving component can be adjusted according to product requirements.

[0087] <Embodiment IV>

[0088] In this embodiment, for the parts that are the same as those in the above embodiment, the same reference numerals are given and the same text descriptions are omitted.

[0089] As Figure 23 、 Figure 24 shown, this embodiment provides a packaging device 400 for chip packaging. The chip is placed in the carrier tape of the packaging device and encapsulated by the cover tape. The packaging device 400 includes a base 430. A conveying device 100 is provided on the base 430. The base 430 can support the conveying device 100 and can adjust the position of the conveying device 100 at the same time. A first detection component 410 and a second detection component 420 are arranged at intervals above the conveying device 100. The first detection component 410 detects the incoming workpiece. When the workpiece enters the carrier tape of the second straight rail component 120, the appearance quality of the workpiece is detected by the first detection component 410. Then the carrier tape continues to move backward, and the carrier tape and the cover tape are heat-pressed and sealed by the hot pressing and sealing component 440. The cover tape is fed by the cover tape feeding component 460. After sealing, the packaged workpiece is detected by the second detection component 420 to check whether the packaged workpiece is abnormal and whether the sealing trace meets the requirements. Both the first and second detection components are existing vision detection devices. The packaged carrier tape is rolled up by the material receiving component 450 for easy storage. The cutting component 160 is arranged downstream of the hot pressing and sealing component 440. When the carrier tape needs to be cut, it is cut by the cutting component 160. The packaging device 400 is controlled by a control module, and the control module is arranged in the electric control cabinet 470. The packaging method of the packaging device in this embodiment will be further described below.

[0090] Referring to Figure 25 shown, the packaging method of the packaging device 400 includes the following steps:

[0091] S100: Thread the carrier tape 200 through the first linear channel 10. The carrier tape 200 enters the second linear channel 20 through the bending channel 30, and then thread the cover tape 300 through the second linear channel 20. The cover tape 300 is located above the carrier tape 200. In this embodiment, the carrier tape and the cover tape are manually threaded. The carrier tape is threaded through the feed port 102 until it enters the second linear channel 20 and engages with the pinwheel. The cover tape is threaded through the cover tape inlet 1280. After threading the carrier tape and the cover tape, the pinwheel returns to zero.

[0092] S200: Receive the workpiece through the second linear channel 20. After the workpiece is picked up by a picking mechanism such as a suction nozzle and placed into the inlet 1261 of the second linear channel 20, the pinwheel 173 rotates step by step to advance the carrier tape. When the carrier tape moves below the first detection component 410, the inlet workpiece is detected by the first detection component 410.

[0093] S300: The carrier tape 200 and the cover tape 300 are heat-pressed and sealed by the heat-pressing and sealing component 400, and then detected by the second detection component 420.

[0094] S400: The take-up component 450 winds up the carrier tape. After it is full, the carrier tape is cut off by the cutting component 160.

[0095] In the above Embodiments 1 to 4, during the working process, with different working environments, some technical implementation manners of Embodiments 1 to 4 can be combined or replaced.

[0096] The technical principle of the present invention has been described above in combination with specific implementation manners. However, it should be noted that the above descriptions are only for explaining the principle of the present invention and cannot be construed as a specific limitation on the protection scope of the present invention in any way. Based on this explanation, those skilled in the art can think of other specific implementation manners or equivalent replacements of the present invention without creative labor, and all will fall within the protection scope of the present invention.
